  1. Concluding remarks

    Patrick, W.C.


    This section contains the concluding remarks of the workshop on rock mechanics issues in repository design and performance assessment. Technical issues such as spatial variability of rock properties, rock mass strength, measurement of loads, evaluation of long-term seal performance, and integration of data into design were discussed. Programmatic issues such as development of a coherent and consistent design methodology and implementation of that methodology were also reiterated

  2. Concluding remarks

    This document provides the speech presented by Hideki Nariai on May 2007 at the workshop on transparency of nuclear regulatory activities. It aims to propose concluding remarks concerning nuclear safety and the necessity to be transparent to the general public. (A.L.B.)

  3. Concluding remarks: Faraday Discussion on chemistry in the urban atmosphere.

    Jimenez, Jose L


    This article summarises the Concluding remarks from the Faraday Discussion on Chemistry in the Urban Atmosphere. The following themes are addressed: (a) new results that inform our understanding of the evolving sources and composition of the urban atmosphere ("News"); (b) results that identify gaps in our understanding that necessitate further work ("Gaps"); (c) the emerging instrumentation revolution and some of the challenges that it brings; (d) the structural issues of insufficient support for the analysis of field campaigns; and (e) some important areas that were missing from this Faraday Discussion and that should receive an increasing focus in the future.

  4. Concluding remarks

    Vogt, E.


    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

  5. Concluding remarks

    McCrea, W.H.


    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.)

  6. Concluding remarks

    Collier, J.G.


    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)

  7. Concluding theoretical remarks

    Ellis, J.


    My task in this talk is to review the happenings of this workshop from a theoretical perspective, and to emphasize lines for possible future research. My remarks are organized into a theoretical overview of the what, why, (mainly the hierarchy problem) how, (supersymmetry must be broken: softly or spontaneously, and if the latter, by means of a new U tilde(1) gauge group or through the chiral superfields) when (how heavy are supersymmetric partner particles in different types of theories) and where (can one find evidence for) supersymmetry. In the last part are discussed various ongoing and future searches for photinos γ tilde, gravitinos G tilde, the U vector boson, shiggses H tilde, squarks q tilde and sleptons l tilde, gluinos g tilde, winos W tilde and other gauginos, as well as hunts for indirect effects of supersymmetry, such as for example in baryon decay. Finally there is a little message of encouragement to our experimental colleagues, based on historical precedent. (orig.)

  8. Summary and concluding remarks

    Vogt, E.


    Although most talks and discussions at the Bad Honnef conference were devoted to the science of the KAON Factory, it is the prospect of the imminent emergence of Canada's KAON Factory that evoked this meeting. Because of the many different kinds of beams provided by KAON, it will offer science opportunities pertinent to many of the current important issues. These include strong interaction physics problems such as hadron spectroscopy, hypernuclei, K + -nucleus scattering, and spin effects in N N scattering; antiproton physics issues; and electroweak physics issues involving tests of the standard model. It is expected that the cost of KAON will be shared among the governments of Canada and other participating countries

  10. Quark Matter '87: Concluding remarks

    Gyulassy, M.


    This year marked the beginning of the experimental program at BNL and CERN to probe the properties of ultra dense hadronic matter and to search for the quark-gluon plasma phase of matter. Possible implications of the preliminary findings are discussed. Problems needing further theoretical and experimental study are pointed out. 50 refs

  11. Concluding remarks for ECRIS '02

    Lyneis, Claude


    ECRIS'02 was held in Jyvaeskylae Finland at the edge of Lake Jyvaeskylae, which was beautiful location to meet and discuss the state of Electron Cyclotron Resonance ion sources. It was the 15th ECR Ion Source Workshop in a series stretching back to the first workshop held November 6, 1978 in Karlsruhe Germany. Overall, the workshop reports could be characterized as showing solid achievements and steady progress without any spectacular breakthroughs or highly controversial new ideas. In this short report, I will mention some of the highlights and surprises of the workshop that I observed during the meeting and reported on at the close of the meeting. As such, it will be relatively brief and not meant to be all encompassing. A short list of items that made this workshop memorable is given

  12. Development of REI meetings (concluding remarks)

    Roessler, K.


    It is an honour and a pleasure to deliver the concluding remarks of this Fourth International Conference on Radiation Effects in Insulators. After commenting upon the present meeting, the genesis of REI conferences, their aims and position relative to related meetings in radiation and ion implantation research will be treated, particularly in order to inform new-comers. The development of the last four REI meetings will be discussed on the base of a statistical analysis. Some recommendations and an outlook of future trends will be given. (orig.)

  13. Chemical physics of electroactive materials: concluding remarks.

    Rutland, Mark W


    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!

  14. Single molecule microscopy and spectroscopy: concluding remarks.

    van Hulst, Niek F


    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.

    Carpenter, J.M.


    This paper is the transcription of remarks made at the conclusion of the Workshop on Cold Neutron Sources held at the Los Angeles National Laboratory, Los Alamos, New Mexico, March 5--7, 1990. Areas of interest include the following: scattering functions; cold moderator materials; radiation mixing of chemical composition; comparison of some pulsed moderator spectra; hydrogen mixtures; premoderators and shields; composite reflectors; exotic moderator materials; deuterated methanes; mixed moderator materials; and test facility availabilities. 2 refs., 4 figs., 1 tab

  17. Concluding remarks: a progress report on our understanding of jets

    Perola, G.C.; Ferrari, A.


    The authors comment on the talks given at the Torino Workshop on astrophysical jets. The observations presented have not revealed a clear picture of nuclear jets. Concerning large scale jets, people begin to find systematic patterns in the variety of parameters and morphologies. So, this kind of jets is paid most attention to during the Workshop. The authors discuss the general consensus in the basic parameters of jets arisen from the preliminary data. Propagation and confinement of jets, the role of magnetic fields, and some observational tests are briefly reviewed. A final paragraph deals with the origin and termination of jets. (G.J.P.)

  18. Concluding remarks

    Okano, Kunihiko; Kikuchi, Mitsuru


    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.)

  19. Concluding remarks

    Wilkinson, D.H.


    This paper reviews the shift in the emphasis of the conference series that began as the International Conference on High Energy Physics and Nuclear Structure (1963) and evolved to the Particle and Nuclei International Conferences, PANIC, the latest of which was held at CEBAF in 1996. The author reviews the papers presented leading to a better appreciation of the EMC effect,, recent understanding of QCD-based effects and the quark structure of the neutron. The author examines the future roles of HERA and CEBAF in the extension of improved experiments on nuclear structure

  20. Concluding remarks

    Rosen, L.


    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

  1. Concluding Remarks

    Budker, G. I. [Institute of Nuclear Physics, Siberian Department of the USSR Academy Of Sciences, Novosibirsk, Union Of Soviet Socialist Republics (Russian Federation)


    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.

  2. Nanoparticles and self-organisation: the emergence of hierarchical properties from the nanoparticle soup (i.e., the small is getting bigger). Concluding remarks for Faraday Discussion: Nanoparticle Synthesis and Assembly.

    Schiffrin, David J


    Some four years ago, one of the participants in this Discussion (Prof. Nicholas Kotov) predicted that: "within five years we shall see multiple examples of electronic, sensor, optical and other devices utilizing self-assembled superstructures" (N. A. Kotov, J. Mater. Chem., 2011, 21, 16673-16674). Although this prediction came partially to fruition, we have witnessed an unprecedented interest in the properties of materials at the nanoscale. The point highlighted by Kotov, however, was the importance of self-assembly of structures from well characterised building blocks to yield hierarchical structures, hopefully with predictable properties, a concept that is an everyday pursuit of synthetic chemists. This Discussion has brought together researchers from a wide range of disciplines, i.e., colloid science, modelling, nanoparticle synthesis and organisation, magnetic and optical materials, and new imaging methods, within the excellent traditional Faraday Discussion format, to discuss advances in areas relevant to the main theme of the meeting.

  3. Concluding remarks of international symposium on highly excited states in nuclear reactions

    Bernstein, A. M.; Ikegami, H.; Muraoka, M. [eds.


    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.

  4. Concluding remarks. International Conference on Nuclear Physics, Berkeley, California, August 1980

    Feshbach, H.


    Not a conference summary, these concluding remarks consider five major themes that were illuminated during the conference and the problems within them that need to be resolved in the future. The five topics considered and the following: new degrees of freedom (single-particle motion, giant resonances, nuclear molecular resonances, nuclear matter, kaon-produced hypernuclei, implications of the bag model and quantum chromodynamics), new forms of matter, new reaction mechanisms (direct vs compound-nucleus reactions, heavy-ion reactions), new aspects of the weak interactions in nuclei (weak neutral currents, P invariance), and new symmetries. 4 figures

  5. Concluding remarks and outlook: Europhysics conference on flavor-mixing in weak interactions

    Chau, L.L.


    Some comments are offered on the present knowledge of the mixing matrix of Kobayashi and Maskawa and of the dynamics of nonleptonic decay. Also, remarks are made concerning CP violation. Plans for research from 1984 to 1989 are listed briefly. The history of studies on weak interactions is briefly reviewed, and several unanswered questions are stated, such as where are the truth particles, how may they be discovered, what is the mass-generating mechanism for the gauge bosons, how many Z 0 's and W's are there, do neutrinos have mass, and how long do protons live

  6. Concluding remarks presented at the Symposium on heavy ion reaction dynamics on the tandem energy region

    Betts, R.R.


    This paper discusses the divisions between different heavy ion reaction processes. Fusion, deep inelastic, quasi-elastic and elastic interactions are discussed in terms of coupled channel calculations. 20 refs., 8 figs

  7. Concluding Remarks: The Current Status and Future Prospects for GRB Astronomy

    Gehrels, Neil


    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.

  8. Concluding remarks of the International symposium on structure and reactions of unstable nuclei

    Mueller, A.C.


    A brief history of unstable beams is given, followed by a short description of the experimental facilities. The structure and reaction of unstable nuclei is discussed, and the neutron-halo nuclei are studied. Some considerations are given related to exotic-beam facilities. (K.A.) 14 refs., 2 figs

  9. Concluding remarks: overall impacts on biodiversity and future perspectives for conservation in the Pantanal biome.

    Alho, C J R


    The Pantanal biome is characterised by seasonal flooding which determines specific ecosystem processes, with the occurrence of adapted plants and animals to the annual shrinking and expansion of habitats due to the seasonal hydrological regime. Biodiversity abundance varies during the dry and wet seasons. The Pantanal's biodiversity is a fundamental component of ecosystem services for human society, including nutrient cycling, fish production, ecotourism, carbon storage, flood control, among others, which are relevant to regional and global environmental consequences. The biome has been impacted by the conversion of natural vegetation into agricultural fields and pasture for cattle raising, with alteration and loss of natural habitats and biodiversity. Major negative impacts occur in uplands, with drastic deforestation of savanna vegetation, where main rivers feeding the Pantanal have their springs. This article discusses future needs and priorities for ecological research, in order to better understand the biome's natural system, to achieve conservation and sustainable use.

  11. Concluding Remarks%序

    Sunney I.Chan


    @@ Thank you for your kind introduction, T.L. I am, of course, honored to have been the Honorary Chairman of ISOC 4, and I thank the Organizing Committee for bestowing this honoron me. As you know, I am not a card- carrying organic chemist, and one might wonder what a physical biochemist could really contribute to this Symposium. But, as Professor Chi - Huey Wong noted during his keynote address, I am over the hill in my own field. Perhaps, my colleagues at CUHK think I might be able to begin a second career as an organic chemist. Lest you question the seriousness of this suggestion, my students and I have recently published in the Journal of Organic Chemistry and Tetrahedron Letters!

    Campbell, S. J.


    An overview of the main aspects of ICAME2011 – tutorial lectures, oral and poster presentations, evening sessions - is presented along with a brief outline of several of the scientific highlights. Among other topics considered are the involvements of young scientists and female scientists, and operation of the oral and poster sessions. Despite the most challenging combinations of circumstances in the lead up to ICAME2011 that resulted in the change of venue at an advanced stage from Tokyo to Kobe, the Committee organised a high quality conference with many positive outcomes for the future. The Mössbauer community acknowledges and appreciates these efforts greatly.

  15. Concluding remarks on future facilities

    Jean-Marie, B.


    The principles of some of the facilities and projects for the study of hadron spectroscopy are summarized. The work is focalized on e + e - machines, which are classified according to the quark family they can study: U,D,S quark families, C quark and τ studies and B quark family. The analysis leads to the conclusion that high luminosity e + e - machines are needed to progress in the hadron spectroscopy exploration

  16. Concluding Remarks and Future Outlook

    Durrani, S. A.; Ilić, R.

    Any reader who has perused the whole of this book with some care will, we believe, be struck by the great breadth and depth of the studies that have been, and are being, carried out on the whole gamut of radon research. These range from geological considerations and investigations that form the essential background to the causes and rates of emission of radon, through economically beneficial applications of the gas such as mineral exploration and search for geothermal energy sources, all the way to indoor and outdoor surveys of radon concentration levels, and critical appraisals of the health hazards of excessive exposure to radon and the measures that can be taken to minimize any deleterious effects - whether to the general public or to those working in mines and caves. And all through the book runs the unifying thread, linking its various parts: the theme-line of Solid State Nuclear Track Detection (SSNTD). This, as we stated in the Preface, is the technique that is most commonly used today for studying the many and various aspects of radon measurements and applications. Several sections of the book have, therefore, been devoted to giving the reader a broad background to the SSNTD discipline and also providing him or her with detailed descriptions of all the various types of instrumentation and devices (both "passive" and "active") used in applications ranging from simple determination of radon concentration levels in homes to earthquake prediction and volcanic surveillance - not to forget the important subject of calibration and standardization of the detectors…

  1. Anticoagulant rodenticides and wildlife: Concluding remarks

    van den Brink, Nico W.; Elliott, John E.; Shore, Richard F.; Rattner, Barnett A.


    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 and bait placement. Another key factor that affects the interaction between ARs and wildlife is the development of resistance in target species. The development of resistance has resulted in higher use of SGARs, thereby increasing the potential of non-target and secondary exposure. AR use has increasingly become more strictly regulated, increasing the need for alternatives. Alternatives are available, including non-anticoagulant rodenticides, but these may also pose significant risk to environmental organisms, humans and pets. There are also various mitigation measures that can be implemented when using ARs, including bait protection, pulsed baiting at the onset of infestation, restricting use by non-professionals, and avoiding use in areas of high non-target density. Reduction in secondary exposure may result from e.g. non-chemical control, habitat management, and, in agricultural habitats, the use of lure crops and supplemental feeding. Such Integrated Pest Management (IPM) may not only reduce non-target exposure but also benefit resistance management. Barriers to adopt IPM approaches however, include the perception that they do not work or too slowly and are more laborious, expensive and time consuming. It is therefore important that the expectations of stakeholders are considered and managed. Nevertheless, further development of alternatives and IPM measures is essential, so the key research priority related to rodent control may ultimately be to address the lack of scientific assessment of the effectiveness of both specific AR mitigation measures and of IPM approaches to rodent control.

  2. Critical remarks on the risk/benefit discussion on mammography from the clinical point of view

    Frischbier, H.J.; Wuerthner, K.


    Arguments pro and contra mammographical mass radiology are discussed. The control intervals should be adjusted, according to the age or, in the individual cases, to the individual risk; this could help to reduce radiation exposition of women below the age of 50 without totally leaving mammography out of prevention. Technical improvements could make dose saving possible. (VJ) [de

  3. Remarks presented (questions/answers discussed) at public regional meetings to discuss regulations (10 CFR Part 21) for reporting of defects and noncompliance, July 12--26, 1977


    In enacting the Energy Reorganization Act of 1974, Congress included Section 206 which requires the reporting of defects and noncompliances directly to the Nuclear Regulatory Commission (NRC). This congressional action required that the NRC promulgate rules and regulations, as necessary, to assure appropriate implementation of Section 206. In response to this mandate, the NRC drafted a new regulation. Following a period of public comment and revision, the regulation identified as 10 CFR Part 21, Reporting Defects and Noncompliance, was published in a Federal Register Notice on June 6, 1977. To assist NRC licensees and other firms and organizations covered by the new Part 21 regulation, public regional meetings were conducted by staff representatives to explain the rule. At these meetings the staff presented prepared remarks and answered questions on the meaning and application of the rule. Staff remarks contained in the original publication of this document were also provided to those in attendance. At each meeting the staff received a request for the questions and answers discussed by the staff to be made available for use as guidance by the nuclear industry covered by the rule. It was announced that a consolidation of the staff position question/answer guidance would be made available to each organization or firm attending these meetings and for others where a request is made in accordance with the directions printed insidethe front cover of the document. The staff will be guided in its implementation and enforcement of Part 21 by the positions set forth in the document. The revision of NUREG-0302 includes the following three parts relating to 10 CFR Part 21: (1) remarks presented by staff representatives; (2) Federal Register Notice material; and (3) a consolidation of questions and answers from the public regional meetings

  4. Chairperson's concluding statement

    Bennett, B.G.


    The Chairperson, on behalf of organizers and sponsors of this conference, expressed his gratitude for the many specialists from many countries, who compiled the expert reports that form the basis of the conclusions and recommendations of the Chernobyl Forum. The expert reports were prepared in a remarkably short time frame. Obviously those involved made considerable effort to complete their work in a timely fashion. They addressed the most important issues related to the accident and the recovery process, and they produced the most complete and useful compilation of information and results available at present. Their clarity and objective presentation have enabled not only scientists but also government representatives and politicians to accept the conclusions. The Chernobyl Forum will be judged successful in large part from the good work of the expert groups. The Chernobyl Forum will also be judged successful from the participation all along of government representative of Belarus, the Russian Federation, and Ukraine. Their good will and understanding have ensured that there will be wide acceptance of the Forum's recommendations and effective measures will be taken with the encouragement of international organizations. We all have great expectations for progress and continued alleviation of the consequences of the accident, for the economic development of the whole region, and for the improvement in public health that we all aspire and strive for. He also extended his thanks to the International Atomic Energy Agency for organizing the Chernobyl Forum. Personal words of thanks went to Mr. ElBaradei for the original initiative that he proposed to bring agreement from disputes, to bring concerted and coordinated efforts to measures still needed to improve public health and to bring consensus as the basis for future actions. He also thanks the many other international organizations that have joined with IAEA in sponsoring the Chernobyl Forum. The World Health

    Hoekman, Bernard; Martin, Will; Mattoo, Aaditya


    The Doha Round must be concluded not because it will produce dramatic liberalization but because it will create greater security of market access. Its conclusion would strengthen, symbolically and substantively, the WTO s valuable role in restraining protectionism in the current downturn. What is on the table would constrain the scope for tariff protection in all goods, ban agricultural ex...

  6. Concluding remarks: Reflections on the forty year's history of TNF

    Martin, L.W.


    The History of NATO's TNF policy is much wider than it may first appear, for NATO TNF policy has been the heart of the whole nuclear question since shortly after it was first so dramatically posed in 1945. Admittedly the ultimate foundation of deterrence has been the overarching balance of strategic nuclear weapons between the two Superpowers. These have provided the strategic open-quotes monitorclose quotes of ultimately unacceptable damage that inspires cautious behavior at lower levels of conflict. But if the strategic weapons inculcate the caution, it has been with TNF that the opposing blocs have chiefly tried to harness nuclear weapons to particular situations and manipulate them to their advantage. The key characteristic of nuclear weapons that distinguishes them from all others is their virtually unlimited destructive potential. Powers disposing of large strategic nuclear forces cannot readily, perhaps ever, be deprived of an ultimate capacity to do outrageous harm. If they are to be defeated, it must therefore be by outmaneuvering them so that they yield the essential prizes without recourse to their worst possibilities. If nuclear weapons are to be used in this process, whether actually or by latent influence on particular issues, it must be in some limited form. NATO's TNF policy constitutes the best example of this so far in nuclear history

  9. Concluding remarks: Where do we go from here?

    Farland, W.H. [Environmental Protection Agency, Washington, DC (United States)


    Where do we go from here in terms of access and use of information resources in assessing health risks from chemical exposure? We will need to look at new applications of relevant information available to programs at the federal, regional, and state levels and try to develop additional hands-on tools that will allow all of us to do our jobs. The application of available information to program decision-making and to risk management is one of the most important things that confronts us.

  10. A neurologist's reflections on boxing. V. Conclude remarks.

    Unterharnscheidt, F


    Clinical and morphological publications have shown convincingly, that participation in boxing leads to a severe permanent brain damage. The extent of the brain damage is correlated to the number of bouts fought, which correspondents in a certain way how many blows against his head a boxer received and to his weight class. The intensity of a boxing blow of a heavyweight is much more severe than those achieved by boxers of lighter weight classes. The permanent brain damage in a boxer, the amateur and the professional boxer, manifests itself in several clinical syndromes in which the pyramidal, the extrapyramidal and the cerebellar systems are involved. A traumatic Parkinsonism, in its complete or abortive form, develops as the result of the numerous boxing blows a boxer sustains in his boxing career. Especially lateral parts of the substantia nigra are affected and reveal at macroscopical and microscopical examination a severe loss of pigmented neurons. Melanin pigment is visible free in the tissue and/or is phagozytosed in macrophages and glial cells. The traumatic Parkinson syndrome, often only in an abortive form, is combined in a boxer with additional clinical and morphological findings due to traumatic lesions in other areas of the brain. It is not as pure as in a patient with a Parkinson syndrome sui generis. The permanent brain damage in a boxer is diffuse, involving all areas of the brain. Especially involved are the large neurons of different layers of the cerebral cortex, the neurons of the Ammons horn formation, the Purkinje cells of the cerebellum. In place of destroyed and lost neurons, proliferation of glial elements, especially astroglial cells, has occurred. The defects are first replaced by protoplasmatic astroglial elements, and later by fibrillary astroglia. The destroyed neurons are replaced by glial scar tissue, which cannot perform the functions of the lost neurons. It is a process which is called partial necrosis of brain tissue. There is no reparation or restitution of the destroyed neural tissue of the brain. What is destroyed remains so, a restitution ad integrum does not occur. As the result of the diffuse loss of neurons in the brain a cerebral atrophy exists. The septum pellucidum, which consists of two thin lamellae, and is small or very small in a normal brain, forms a Cavum septi pellucidi, which is considerably enlarged. The walls of this structure, especially in its dorsal parts are considerably thinned; they show fenestrations and are, in dorsal parts no longer detectable, so that a direct connection between the two lateral ventricles exists. The clinically and morphologically existing permanent brain damage is the result of the boxing activity. Diagnostically, processes of another origin, such as alcoholism, luetic processes, other forms of dementia, etc. can undoubtedly be excluded. A permanent brain damage develops in professional and amateur boxers. The objection, which are voiced by members of the different Amateur Boxing Association, that such permanent brain damage in amateur boxers today no longer exists, after stricter protective measurements were introduced, is not tenable. Individuals who represent today the opinion, that a permanent brain damage or punch drunkenness in boxers does not occur, are not familiar with the pertinent medical literature. The argument, the injury quotient in boxing is lower than in all other athletic activities is not sound, since the statistics show only the inconsequential injuries of boxers, as lesions of the skin of the face, injuries of the hand, fractures, etc. but not the much more important and severe permanent brain damage, which is not taken into consideration in these so-called statistics. Besides of the permanent brain damage of former boxers as the result of the repeated and numerous blows against their head, severe permanent damage of the eyes and the hearing organ exists.

  11. Discussion

    Mittleman, M.H.


    The positive energy projection operators, just described by Prof. Sucher, convert the sick Hamiltonian, H/sub DC/, into a more robust one which can support bound states. They are however still a subject of some controversy. Prof. Grant pointed out that existing computer codes produce remarkable accuracy in numerical calculations which start from H/sub DC/ (with no projection operators) and so he questioned whether these operators were indeed necessary. In response, it was pointed out by several people in the audience that the codes implicitly limit the Dirac-Hartee-Fock wave functions to a normalizable sub-space and that this operation can be described as a projection operator which has the effect of eliminating the negative energy states which are not normalizable. This operation is however, not any of the three projection operators described by Sucher and so the question arises as to the sensitivity of the results (for the energy and wave functions) to the particular projection operators which are used. This appears to be an open question

  17. Welcome remarks

    Zhao Hong


    In his opening remarks Mr. Zhao Hong stressed the importance of nuclear power for further economic development. He noticed that one of the main factors to obstruct the progress of nuclear energy is nuclear dread in public psychology and that enhancement of the public acceptance of nuclear power is an important task to promote the development of nuclear power. Than he described activities in China in public relation work in the field of nuclear energy. Importance of international cooperation on peaceful use of nuclear energy and supporting non-proliferation regime was stressed

  18. Opening remarks

    Southwood, Richard


    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.)

  19. Introductory remarks by Augusto Ancarani[Roundtable discussion on whether the advocates of nuclear power and the adversaries are listening to each other

    Ancarani, Augusto [Commission of the European Communities, Brussels (Belgium)


    The subject proposed for the present roundtable is in the form of a twofold question. To assert that advocates and adversaries of nuclear power are listening to each other will hopefully result from what will be said. But, as far as the chance of a dialogue is concerned, one can answer in the positive from the start. Indeed a dialogue is always possible, even among deaf people, provided they are polite. This has been and still is the situation in many instances. If we consider the politics situation in a worldwide perspective, we hove to acknowledge that the mood is favorable to the dialogue on almost every possible subject. If this is true among the great powers, it will also be the case, at all the Levels, inside our democratic and articulate societies, O rice set in motion the solution of the great problems concerning peace among notions, still remain to be tackled the ones about the welfare of humankind. Such welfare rests heavily on the availability of energy; besides, energy cannot bp produced without some consequences upon the environment. This process will bi a Long and a difficult one; it will be exhausted only through confrontations, exchanges of view, dialogues, discussions - any term that you will care to choose.

    Full Text Available An energy system that is based on the use of renewable energy resources must be service –oriented and should be able to cover the varying energy demands. Moreover it must be flexible and cost effective by using on optimal mix of predominantly renewable energy sources. Agriculture will play an important role in the future if an optimal mix between food/feed production and energy plant production could be found. The present examples in the world to gain agricultural land for energy plants on the expenses of forests is going into the wrong direction. The cost intensive investments at present performed in Europe for biofuel and bioenergy production will certainly influence prices for crops and biomass supply. In this paper, strategies are questioned and discussed if the goals of the EU-commission to replace substantial parts of the fossile energy demands by bioenergy supply is feasible and can be realistic. As an example for a national agricultural situation, Austria, as am member of the PBBA, has elaborated a study about the timely development how much of the arable land can be utilized in the period between 2005 and 2020 for various bioenergy sources .The results demonstrate that, at the maximum , agriculture can only supply about 22 % of the total arable land for additional bioenergy as biofuel and biogas without interfering the national self food/feed supply and the protection of the sensible environment and emission situation. Finally, recent University research studies are presented about new processes to achieve a better and more efficient use of cereal and maize straw for biogas production already performed in the present 358 local biogas plants in Austria.

  2. Closing remarks

    Reig, J.


    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)

  3. Introductory remarks

    Soyeur, Madeleine.


    This paper introduces the discussion of the new aspects of nuclear studies with electrons and photons. It is mainly concerned with the short range part of the nuclear force and with the quark and gluon degrees of freedom that we believe are associated with it. The present description of the nucleon-nucleon force in non relativistic quark models and in bag models is reviewed. The assumption of a '6 quark' component in the deuteron and the possible existence of dibaryons are discussed

  7. Concluding Remarks on the International Symposium on Exotic Nuclear Systems ENS'05

    Habs, D.


    In nuclear physics within Europe we observe a strong concentration onto a few large-scale facilities like FAIR, ALICE and EURISOL, which at the same time results in a strong focus of all resources towards these facilities. My personal belief is, that we need in Europe in addition a broad network of smaller institutes with local nuclear physics for a healthy structure of our science. I propose two fields of nuclear science onto which these smaller institutes may focus: (i) Fundamental Physics, studying physics beyond the Standard Model with high precision measurements at low energies and (ii) joining Advanced Photon Science, where new high energy photon and particle beams become available in compact devices at low cost. While such networks are planned or exist already among different universities in Germany for these two subjects, I propose to extend these towards a European networks within the 7th framework. A first starting point could be associations with the German networks, funded by the German Science Foundation DFG

  9. Concluding Remarks: A View of the Past through the Lens of the Present.

    Bensaude-Vincent, Bernadette


    Reflecting on the upsurge of interest among historians of chemistry in the material, artisanal, and commercial aspects of early modern chemistry, this essay argues that they are attracting attention because of a number of similarities between the style of chemistry cultivated in this period and the new cultures of chemistry being developed today. The close interactions between knowing and making, academic knowledge and practical applications, the social value and prestige attached to chemistry, the public engagement in chemical culture, the concern with recycling, and even a specific relational ontology instantiated in the term "rapport" are characteristic features of the current technoscientific culture. However, these analogies between early modern chemistry and the technoscientific paradigm may turn into obstacles if they end up in hasty rapprochements and whiggish interpretations of the past. In keeping with the attempts displayed in many articles in this volume to identify and understand the meaning of the actors' categories, this essay emphasizes the contrast between the visions of the past and the future developed by eighteenth-century chemists and the concept of time that prevails nowadays. The concept of "regime of historicity" provides a useful conceptual tool to take a view of chemistry as embedded in a culture and integral part of the horizon of expectation of an epoch. On the basis of this contrast between the regimes of historicity, the essay recommends the pluralism of concepts of time (polychronism) as an antidote to anachronisms.

  10. Remarks on superconductive networks

    Dominguez, D.; Lopez, A.R.N.; Simonin, J.M.


    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)

  11. IAEA Remediation Mission to Japan Concludes


    classifying removed materials that do not warrant special radiation protection measures as ''radioactive waste''; - Japan is advised to consider explaining to the public the importance of focusing on radiation doses that may actually be received by people rather than on data indicating contamination levels; and - Japan is encouraged to continue its remediation efforts. In doing so, Japan is encouraged to take into account the advice provided by the Mission. The IAEA stands ready to support Japan as it considers new and appropriate criteria for such activities. The authorities and local residents in Japan fully assisted the IAEA international team in its endeavor to conclude its mission successfully. ''The team also appreciates the openness with which our discussions were conducted and the high level of cooperation and access we were granted by Japan,'' says Mr. Lentijo. ''This was an invaluable opportunity for us to learn from this important decontamination initiative. We would like to continue our support to Japan in this very challenging task. We look forward to sharing our findings with the international community.'' The final report of the mission will be presented to the Government of Japan in the next month. Background. The accident at the Fukushima Dai-ichi Nuclear Power Plant has led to elevated levels of radiation over large areas. The Government of Japan has been formulating a strategy and plans to implement countermeasures to remediate these areas. The IAEA organized an International Fact Finding Expert Mission of the Fukushima Dai-ichi Nuclear Power Plant Accident Following The Great East Japan Earthquake and Tsunami, which took place between 24 May and 2 June 2011. The mission concluded today is a follow-up to the fact-finding mission held earlier in the year and an essential component of the IAEA's Nuclear Safety Action Plan, approved by the IAEA Board of Governors on 13 September and endorsed by all 151 Member States at the recent IAEA General Conference in

  18. IAEA Director General's concluding remarks. Meeting of the Contracting Parties to the Convention on Nuclear Safety. Vienna, 26 April 2002

    ElBaradei, M.


    The Convention on Nuclear Safety is considered as a part of the overall nuclear safety regime. That regime has many components, but they all have one single objective - to make sure that safety is at as high a level as possible. The Convention is a living process, a process which should eventually lead to increasingly greater safety. The Meting has focused on a number of issues that are also priorities for the Agency; one such issue is safety culture. The effectiveness and transparency are key issues. A second issue which is highlighted is management of nuclear knowledge. Other high priority issues which were identified include: planned life extension; the need during life extension to look into the ageing of equipment and structures; deregulation and its impact on safety; and the question of periodic safety reviews. The question of co-operation between regulatory bodies is one that was given emphasis to over the last few years. It is very important that there be exchange of experience and exchange of expertise between regulatory bodies, and between the manufacturers of power reactors and the countries where the reactors are operated. Also of importance in terms of international co-operation is the development of adequate emergency response everywhere. A major point that which is left to the participating countries is that although safety is a national responsibility - there is absolutely no question about that -many issues need international co-operation

  19. Concluding remarks: what's in a name? "Negritos" in the context of the human prehistory of Southeast Asia.

    Ulijaszek, Stanley J


    The "negrito" hypothesis posits that various indigenous groups throughout Island and Mainland Southeast Asia have a shared phenotype due to common descent from a putative ancestral population, representing a pre-agricultural substrate of humanity in the region. This has been examined and tested many times in the past, with no clear resolution. With many new resources to hand, the articles in this volume reexamine this hypothesis in a range of different ways. The evidence presented in this double issue of Human Biology speaks more against the category of "negrito" than for it. While populations with the negrito phenotype form a small proportion of all contemporary populations in this region, they have remained a persistent presence. And without a fascination about their origins, there would not be such a depth of knowledge about the human biology of this region more broadly as there is now.

  20. Remarks of Joseph Marrone

    Marrone, J.


    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

  1. Remarks on stellar clusters

    Teller, E.


    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)

  3. [Some remarks on the present discussion on underdevelopment].

    Khalatbari, P


    Along with the threat of atomic war, the chronic poverty of 3/4 of the world's population is a further aspect of the crisis of today's civilization. Underdevelopment and backwardness are not identical concepts, as the latter is rooted in traditional, manual agricultural production that over 300 years of colonial capitalistic production upset without transforming by using colonies for raw material production and eventually after the First World War for industrial production. Today 75% of peasant families in Latin America and 97% in Africa cultivate their land using backward traditional methods, and 60% of land in developing countries is owned by large estate landlords. Vaccination against epidemics and public health measures of new independent countries lowered mortality without a corresponding reduction of fertility resulting in increasing population and a youthful structure. The number of women in reproductive age was 397 million in 1956, rose to 812 million in 1985, and is expected to soar to over 1.7 billion by 2025. Even if the birth rate were to drop to 18.6/1000 by 2025 as the UN estimates, this will continue the increase of world population for decades. The disturbance of the demoeconomical balance, the inability to absorb the ever increasing population is the dilemma of developing countries. The number of unemployed will rise to 800 million by 2000 from 500 million in 1989. There are 600 million malnourished people, and every year 14-15 million die because of deficient diet and hunger. The shortage of land leads to deforestation: 12% of tropical forests will be cut down by 2000 and desert areas will triple. Peasants displaced by modern agricultural mass production and landlessness flock to cities expanding the numbers of paupers that are easy to radicalize by adventurers who could resort to solutions by atomic blackmail.

  4. Seven remarkable days

    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...

  5. Remarkable resilience of teeth.

    Chai, Herzl; Lee, James J-W; Constantino, Paul J; Lucas, Peter W; Lawn, Brian R


    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.

  6. IAEA Expert Team Concludes Mission to Onagawa NPP


    Full text: An IAEA team of international experts today delivered its initial report at the end of a two-week mission to gather information about the effects of the Great East Japan Earthquake on the Onagawa Nuclear Power Station (NPS), saying the plant was 'remarkably undamaged'. Findings from the visual investigation will be added to an IAEA data base being compiled by its International Seismic Safety Centre (ISSC) to provide knowledge for Member States about the impact of external hazards on nuclear power plants. The ISSC data bank makes an important contribution to the IAEA's Action Plan on Nuclear Safety, which was unanimously endorsed by the Agency's Member States following last year's nuclear accident at Fukushima Daiichi NPS. Onagawa, facing the Pacific Ocean on Japan's north-east coast, was the nuclear power plant closest to the epicentre of the 11 March 2011 magnitude 9.0 earthquake that struck Japan and resulted in a devastating tsunami. The plant experienced very high levels of ground shaking - among the strongest of any plant affected by the earthquake - and some flooding from the tsunami that followed, but was able to shut down safely. In its draft report the team said that 'the structural elements of the NPS were remarkably undamaged given the magnitude of ground motion experienced and the duration and size of this great earthquake'. The mission's objective was to observe how structures, systems and components with significance to the safety of the plant responded to the earthquake and heavy shaking. At the damaged Fukushima Daiichi NPS, nearly 120 km south of Onagawa NPS, the effects of the earthquake, tsunami and hydrogen explosions make it impossible to single out the impact of external hazards on safety-related parts of the power station. The Government of Japan and the IAEA therefore agreed to deploy a mission to the three-unit Onagawa NPS. The team's 19 members from six countries, including IAEA staff, held discussions with the operators of the

  7. Remarks on energetic biomass

    Mathis, Paul; Pelletier, Georges


    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

  10. Remarks on entanglement swapping

    Song, Daegene


    In two partially entangled states, entanglement swapping by Bell measurement will yield the weaker entanglement of the two. This scheme is optimal because the average entanglement cannot increase under local operation and classical communication. However, for more than two states, this scheme does not always yield the weakest link. We consider projective measurements other than Bell-type measurement and show, numerically, that while Bell measurement may not be unique, it is indeed optimal among these projective measurements. We also discuss the non-uniqueness of Bell measurements. (letter to the editor)

  11. Remarks on transparent adverbs

    Daria Protopopescu


    Full Text Available The paper explores the contrast arising between subject/object oriented depictives and manner adverbs. We adopt Geuder’s (2004 label of “transparent” adverbs and embark upon a comparison between this particular class and manner adverbs in English and Romanian, with a look at depictive constructions as well. The problem discussed here is the ambiguity arising in Romanian where most such adverbs seem to overlap their corresponding adjectival forms. Tests will show where they have to be adjoined and the possible readings which they are attached.

  12. Closing Remarks and Awards

    Whitaker, M.; Van der Meer, K.; Hamilton, A.


    M. Whitaker: On behalf of the Institute of Nuclear Materials Management, we are grateful for the opportunity to support this symposium. The number of symposium events-presentations, posters, technical demonstrations, panel discussions, and receptions - has been completely overwhelming and truly impressive. My compliments to the IAEA organization staff for a spectacular event. I have gained a much better appreciation for why these are only once every four years. This symposium has provided an important opportunity to reengage with friends and colleagues from around the globe to discuss international safeguards topics. The theme this year is very appropriate. So much of our work relies upon people. Together we work to develop the strategies that ensure that international safeguards are effectively implemented to provide the world the assurances that they expect from us. Thank you for this opportunity to share in the organization and execution of this symposium. K. Van der Meer: It is my pleasure to give the last poster awards. We have had two award ceremonies already this week on Wednesday and Thursday to recognize the best posters in those sessions. Today it will be two parts. First we will give the award for the best posters for this morning's sessions, and then we have four special awards: Gold, Silver, Bronze and the New Generation Symposium Award. These are the awards for the best posters for the whole week. The New Generation Symposium Award is for recognition of a younger participant and the prize is also for a younger participant. The full list of award winners is available under the symposium website. The IAEA recognizes the generous donations by INMM and ESARDA of the following prizes given as awards for the best posters: · Best e-poster advertisement per session: free subscription to the ESARDA Bulletin; · Best e-poster per session: free membership in INMM; · Best poster of the week ''Bronze'': free registration for the 8th INMM

  13. Closing remarks: astronomical

    Pecker, J.-C.


    During the discussions we have covered many facets of the basic interactions between solar activity and the Earth's climate. Solar activity is not the only astronomical or astrophysical phenomenon to influence physical conditions in the biosphere. Over timescales an order of magnitude less, the location of the Solar System in the Galaxy may have influenced life on Earth. The Sun is a complex generator of radiation, particles and magnetic fields sent far into space. Even if the total radiation emitted is constant, the amount of radiation received by the Earth changes with time: this change is complex and involved with a redistribution of energy emitted at different solar latitudes than to a real change in solar luminosity. These changes in the Earth's illumination may be a function of the wavelength, and have various effects in different layers of the Earth's atmosphere. The Sun also emits particles of all energies. Some of them find their way through the magnetopause, giving rise to auroras, to magnetic storms, to ionospheric disturbances and the like. The possible climatological effects are yet obscure. To understand the solar terrestrial relations better, regular, routine observations from ground-based stations and from space of solar phenomena must be continued. The sensitivity of human life to small changes in climatic conditions is very large. A good knowledge of solar-physics is therefore important and relevant. (author)

  14. Momentum distributions: opening remarks

    Weigold, E.


    The problem of the hydrogen atom has played a central role in the development of quantum mechanics, beginning with Bohr's daring speculations. It was also the first problem tackled by Schroedinger with his new wave mechanics and similarly it was used by Heisenberg in his first papers as a prime example of the success of quantum mechanics. It has always played a central role in the teaching of quantum physics and has served as a most important heuristic tool, shaping our intuition and inspiring many expositions. The Schroedinger equation for the hydrogen atom is usually solved in the position representation, the solution to the equation being the wave functions psi/sub nlm/(r). If Schroedinger's equation is solved in the momentum representation instead of the coordinate representation, the absolute square of the corresponding momentum state wave function phi/sub nlm/(p) would give the momentum probability distribution of the electron in the state defined by the quantum numbers n, l and m. Three different types of collisions which can take place in the (e,2e) reaction on atomic hydrogen, which is a three body problem, are discussed

  15. Plenary presentations - opening remarks

    Simon, R.M.


    I am pleased to be here today as one of the U.S. Co-Chairs for the Second U.S./Japan Workshop on Global Change. This series of workshops is an outgrowth of the 1988 bilateral agreement between the U.S. and Japanese governments on scientific and technological cooperation. That agreement called for comparable access to, and exchange of, information in scientific and technological fields, as well as the joint undertaking of cooperative activities for peaceful purposes in nationally important areas of science and technology. Meetings such as this were envisioned under the agreement to allow experts from both sides to discuss and exchange information on scientific and technological aspects of important problems and to identify research and development projects that might usefully be undertaken on a cooperative basis. The first U.S./Japan Workshop on Global Change focused on research needed to better understand how the global climate system operates, what the interactions are between the climate system and marine and terrestrial ecosystems, and how Earth systems might respond to global climatic changes.

  17. Editorial - a remark you made

    Yngve Nordkvelle


    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

  20. IAEA Mission Concludes Peer Review of UK's Nuclear Regulatory Framework


    Full text: Senior international nuclear safety and radiation protection experts today concluded a ten-day International Atomic Energy Agency (IAEA) mission to review the regulatory framework for nuclear and radiation safety in the United Kingdom (UK). The Integrated Regulatory Review Service (IRRS) mission team said in its preliminary findings that the UK had made considerable progress since reviews in 2006 and 2009. It also identified good practices in the country's nuclear regulatory system. In addition to following up previous missions, a key objective was to review the effectiveness of the role of the Office of Nuclear Regulation (ONR), the UK's nuclear regulator, in ensuring the safety of radioactive waste management and decommissioning, occupational radiation protection, and public and environmental exposures, including emergency planning and response. The mission also considered the response of the UK's regulatory regime to the implications of the Fukushima Daichi accident had been timely and effective. Recommendations and suggestions were made to the ONR and the Government aimed at strengthening the effectiveness of the country's regulatory framework and functions in line with IAEA Safety Standards, the control of radioactive discharges and environmental monitoring. 'The staff of ONR is clearly dedicated to their mission to secure the protection of people and society from the hazards of the nuclear industry. I am confident that ONR will use the results of this mission to further enhance their regulatory programs', said Bill Borchardt, mission leader and former Executive Director of the United States Nuclear Regulatory Commission (NRC). 'The staff were open and cooperative in their discussions; they provided the fullest practicable assistance, and accepted advice from the Team for continuous improvement in their regulatory work'. ONR's Chief Executive, John Jenkins, said that the full report of the IRRS mission will enhance regulatory effectiveness in the UK

  1. IAEA Mission Concludes Peer Review of Pakistan's Nuclear Regulatory Framework


    An international team of senior nuclear safety experts today concluded a nine-day International Atomic Energy Agency (IAEA) mission to review the regulatory framework for the safety of operating nuclear power plants in the United States of America (USA). The Integrated Regulatory Review Service (IRRS) mission was a follow-up to the IRRS mission to the US Nuclear Regulatory Commission (NRC) that was conducted in 2010, with the key additional aim of reviewing whether the response of the US regulatory regime to the implications of the accident at TEPCO's Fukushima Daiichi Plant had been timely and effective. The mission team concluded that the recommendations and suggestions made by the 2010 IRRS mission have been taken into account systematically under the NRC's subsequent action plan, with significant progress in many areas and many improvements carried out. One of two recommendations and 19 out of 20 suggestions made by the 2010 IRRS mission have been effectively addressed and can therefore be considered closed. The outstanding recommendation relates to the NRC's review of its Management System, which is in the process of being finalised. The IRRS team also found that the NRC acted promptly and effectively after the Fukushima accident in the interests of public health and safety, and that the report of its Near-Term Task Force represents a sound and ample basis for taking into account the lessons learned from the accident

  2. Team of experts concludes review of safety issues at Temelin


    Full text: At the request of the Czech Government, the International Atomic Energy Agency (IAEA) assembled a team of national experts from Bulgaria, France, Germany, Spain, and the United Kingdom, with an observer from Austria, to review safety issues at the Temelin power plant that were identified in 1996 as relevant to reactors of the generic Temelin design (WWER-1000/320 type). Following a detailed on-site review from 18 to 23 November 2001, the experts concluded that most identified issues had been addressed and resolved. Work is continuing on the few remaining issues. These issues, however, are not judged by them to be significant and would not from the experts' standpoint preclude the safe operation of the Temelin nuclear power plant. The final report of the team of experts will be available to the Czech Government in one month's time. (author)

  4. The Contracting Parties' Ability To Conclude The Employment Contract

    Carmen Constantina NENU


    Full Text Available This study's main objective is to analyze certain effects produced by the changes of the Labor Code and by the entry into force of the current Romanian Civil Code. These effects refer to one of the fundamental conditions for the valid conclusion of the individual employment contract, that is, to the legal capacity of employers and employees. Thus, a complete analysis of legal regulations and of the correlations between different provisions on the legal capacity of parties to the individual employment contract is required to identify the existing noncompliance and to propose solutions. The research demonstrated that the current regulatory framework governing the legal capacity of the parties to an individual employment contract does not entirely correspond to the social reality. Therefore, only the employer benefits from a relatively comprehensive statutory regulation on the legal capacity to conclude an individual employment contract. The employee, however, does not benefit from the same attention from legislature. Considering the above, the study represents a significant scientific contribution, whose value lies in the proposed changes to modify legislature, so that the legal capacity of job holders would benefit from fair regulation, in accordance with the principle of legal protection of employee rights.

  5. Concluding talk: fundamental lessons and challenges from neutrinos

    Altarelli, G


    We present a concise review of the experimental developments on neutrino mixing and their theoretical implications as presented and discussed at this Conference. The recent data disfavour many models but the surviving ones still span a wide range going from Anarchy (no structure, no symmetry in the neutrino sector) to a maximum of symmetry, as for the models based on discrete non-abelian flavour groups which can be improved following the indications from the recent data.

  6. IAEA Mission Concludes Peer Review of Slovenia's Nuclear Regulatory Framework


    Senior international nuclear safety and radiation protection experts today concluded an eight-day International Atomic Energy Agency (IAEA) mission to review the regulatory framework for nuclear and radiation safety at the Slovenian Nuclear Safety Administration (SNSA). The team reviewed measures taken to address the recommendations and suggestions made during an earlier Integrated Regulatory Review Service (IRRS) mission conducted in 2011. The IRRS team said in its preliminary findings that Slovenia had made significant progress since the review in 2011. The team identified a good practice in the country's nuclear regulatory system additional to those identified in 2011 and made new recommendations and suggestions to SNSA and the Government to strengthen the effectiveness of the country's regulatory framework in line with IAEA Safety Standards. ''By hosting a follow-up mission, Slovenia demonstrated its commitment to enhance its regulatory programmes, including by implementing the recommendations of the 2011 mission,'' said Petr Krs, mission leader and Vice Chairman of the Czech Republic's State Office for Nuclear Safety. SNSA's Director, Andrej Stritar, welcomed the progress noted by the team, while also emphasizing that the mission highlighted important future nuclear safety challenges for Slovenia. The five-member review team, comprising experts from Belgium, the Czech Republic, France and Romania, as well as four IAEA staff members, conducted the mission at the request of the Slovenian Government from 9 to 16 September 2014. The main observations of the IRRS Review team included the following: SNSA has made significant progress in addressing the findings of the 2011 IRRS mission and has demonstrated commitment to effective implementation of the IRRS programme; The economic situation in Slovenia might in the short and long term affect SNSA's ability to maintain its capacity and competence; and A radioactive waste disposal project is stalled and the licensing

  7. IAEA Mission Concludes Peer Review of Jordan's Nuclear Regulatory Framework


    Senior international nuclear safety and radiation protection experts today concluded an 11-day International Atomic Energy Agency (IAEA) Integrated Regulatory Review Service (IRRS) mission to review the regulatory framework for nuclear and radiation safety in Jordan. The mission team said in its preliminary findings that Jordan's nuclear regulator, the Energy and Minerals Regulatory Commission (EMRC), faces challenges because it is a relatively new body that handles a high workload while also working to recruit, train and keep competent staff. The team also noted that a recent merger provided the regulator with more of the resources it needs to perform its duty. The team made recommendations and suggestions to the regulatory body and the Government to help them strengthen the effectiveness of Jordan's regulatory framework and functions in line with IAEA Safety Standards. The main observations of the IRRS Review team comprised the following: The regulatory body, founded in 2007 and merged with other regulators in April 2014 to form EMRC, faces large challenges in terms of its regulatory workload, management system building and staff recruitment and training; The new EMRC structure and revision of the radiation and nuclear safety law represents an important opportunity to strengthen Jordan's radiation and nuclear safety infrastructure; The Government has shown commitment to radiation and nuclear safety through measures including becoming party to international conventions. It could further demonstrate its commitment by adopting a formal national policy and strategy for safety that defines the role of the Minister of Energy in relation to EMRC and protects the independence of regulatory decision-making

  8. International IAEA Emergency Response Workshop in Fukushima Concludes


    Full text: An IAEA workshop aimed at further strengthening nuclear and radiological emergency preparedness and response capabilities concluded today in Fukushima, Japan. More than 40 participants from 18 countries took part in the four-day Response and Assistance Network (RANET) workshop, which included a field exercise in areas affected following the March 2011 accident at TEPCO's Fukushima Daiichi Nuclear Power Station. During the exercise, participants conducted radiation monitoring and environmental sampling and analysis. They measured the contamination level of the ground surface and conducted gamma spectrum analysis and vehicle-based monitoring - activities that are conducted following any nuclear or radiological incident or emergency. Results were then compared amongst participants. RANET is a network currently comprising 22 countries through which the IAEA can facilitate the provision of expert support and equipment on request under the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency. Pat Kenny, IAEA RANET Officer, said the workshop provided an opportunity to practice cooperation between international teams that would be deployed through RANET following an emergency. 'By bringing together so many experts from different countries in one place, the workshop helped us learn how international teams can work together to provide assistance in a nuclear or radiological emergency situation,' he said. 'It also enabled us to improve the coordination of such assistance, and it gave participants the opportunity to learn from each other.' The workshop was the first activity conducted from the IAEA RANET Capacity Building Centre, a new training centre based in the city of Fukushima that was designated earlier this week with the support of the Japanese Foreign Ministry and Fukushima Prefecture. The Centre will host RANET and other training courses, workshops and exercises aimed at enhancing nuclear emergency preparedness and response

  9. Remarks on High Energy Evolution

    Kovner, Alex; Lublinsky, Michael


    We make several remarks on the B-JIMWLK hierarchy. First, we present a simple and instructive derivation of this equation by considering an arbitrary projectile wave function with small number of valence gluons. We also generalize the equation by including corrections which incorporate effects of high density in the projectile wave function. Second, we systematically derive the dipole model approximation to the hierarchy. We show that in the dipole approximation the hierarchy has a simplifyin...

  10. IAEA Concludes Safety Review at Gravelines Nuclear Power Plant, France


    Full text: An IAEA-led international team of nuclear safety experts noted a series of good practices and made recommendations to reinforce some safety measures during a review of operational safety at France's Gravelines Nuclear Power Plant (NPP) that concluded today. The Operational Safety Review Team (OSART) was assembled at the French Government's request. The in-depth review, which began 12 November 2012, focused on aspects essential to the safe operation of the NPP. The team was composed of experts from Bulgaria, China, Germany, Hungary, Japan, Romania, Slovakia, South Africa, Spain, Ukraine and the IAEA. The review covered the areas of management, organization and administration; training and qualification; operations; maintenance; technical support; operating experience; radiation protection; chemistry; emergency planning and preparedness; and severe accident management. The conclusions of the review are based on the IAEA's Safety Standards. The OSART team has identified good plant practices, which will be shared with the rest of the nuclear industry for consideration of their possible use elsewhere. Examples include the following: - The Power Plant uses a staff-skills mapping process that significantly enhances knowledge of the facility's collective and individual skills and provides proactive management to address the loss of such skills; - As a measure to reduce the risk of workers' radiation exposure, the Power Plant uses a system to ensure that dose rate measurements are carried out at a precise distance from the source of radiation; and - Flood protection of the Power Plant is supported by special technical guidance documents and associated arrangements. The team identified a number of proposals for improvements to operational safety at Gravelines NPP. Examples include the following: - The Power Plant should reinforce its measures to prevent foreign objects from entering plant systems; - The Power Plant should ensure the 24-hour presence of an operator

  11. What do review papers conclude about food and dietary patterns?

    Elisabet Wirfält


    Full Text Available Nutrients and other bioactive constituents of foods may interact with each other and the surrounding food matrix in complex ways. Therefore, associations between single nutrients and chronic disease may be difficult to identify and interpret, but when dietary patterns (DPs are examined the combination of many food factors will be considered. An explorative literature search of published review articles was conducted to obtain a fuller understanding of current DPs in epidemiological research, to discuss pros and cons of DPs in nutrition research, and to identify results of studies linking DPs to chronic disease risk in adults. Randomized feeding trials providing the experimental diets to study participants have repeatedly demonstrated that diets based on current dietary recommendations are associated with important health benefits. Systematic reviews of feeding trials and prospective population studies of DPs and chronic disease risk reach similar conclusions regardless of the methodology used to construct DPs. However, to date only a few review articles of DP studies have followed a systematic process using independent reviewers with strict inclusion, exclusion, and study quality criteria. Diets with plenty of plants foods, fish, and seafood that preferably include vegetable oils and low-fat dairy products are associated with a lower risk of most chronic diseases. In contrast, Western-type DPs with food products low in essential nutrients and high in energy, like sugar-sweetened beverages, sweets, refined cereals and solid fats (e.g. butter, and high in red and processed meats, are associated with adverse health effects. An emphasis on high-quality original research, and systematic reviews following a structured process to objectively select and judge studies, is needed in order to enforce a strong future knowledge base regarding DPs and chronic disease.

  12. Women's rights advocates achieve victories as UN conference concludes.


    On September 15, 1995, government delegations finished the Platform for Action of the United Nations Fourth World Conference on Women in Beijing, China. In this historic document, individual governments and the international community committed themselves to the advancement of women worldwide. Human rights issues (violence against women and female children, and reproductive freedom and health) were discussed and affirmed. Paragraph 2 of the human rights section states that "the human rights of women and the girl child are an inalienable, integral and indivisible part of universal human rights." Paragraph 9 adds "full realization of all human rights and fundamental freedoms of all women is essential for the empowerment of women." Acknowledging "the significance of national and regional particularities and various historical, cultural and religious backgrounds," the document still calls for "states, regardless of their political, economic and cultural systems, to promote and protect all human rights and fundamental freedoms." The human rights section "reaffirms that [reproductive rights] rest on the recognition of the basic right of all couples and individuals to decide freely and responsibly the number, spacing, and timing of their children and to have the information and means to do so, and the right to attain the highest standard of sexual and reproductive health. It also includes their right to make decisions concerning reproduction free of discrimination, coercion and violence, as expressed in human rights documents." The platform recognizes violence against women and girls in all societies (physical, psychological, and sexual abuse that includes murder; systematic rape; forced pregnancy, sterilization, contraception, and abortion; female infanticide; battering; and trafficking in women that is perpetrated by state and nonstate actors). The section on women and armed conflict declares that "rape in the conduct of armed conflict constitutes a war crime and under

  14. The Social Interplay of Disciplinarity and Interdisciplinarity. Some Introductory Remarks

    Reinhold Hedtke


    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..

  17. Concluding Remarks: Connecting Relativistic Heavy Ion Collisions and Neutron Star Mergers by the Equation of State of Dense Hadron- and Quark Matter as signalled by Gravitational Waves

    Hanauske, Matthias; Steinheimer, Jan; Bovard, Luke; Mukherjee, Ayon; Schramm, Stefan; Takami, Kentaro; Papenfort, Jens; Wechselberger, Natascha; Rezzolla, Luciano; Stöcker, Horst


    The underlying open questions in the fields of general relativistic astrophysics and elementary particle and nuclear physics are strongly connected and their results are interdependent. Although the physical systems are quite different, the 4D-simulation of a merger of a binary system of two neutron stars and the properties of the hot and dense matter created in high energy heavy ion collisions, strongly depend on the equation of state of fundamental elementary matter. Neutron star mergers represent optimal astrophysical laboratories to investigate the QCD phase structure using a spectrogram of the post-merger phase of the emitted gravitational waves. These studies can be supplemented by observations from heavy ion collisions to possibly reach a conclusive picture on the QCD phase structure at high density and temperature. As gravitational waves (GWs) emitted from merging neutron star binaries are on the verge of their first detection, it is important to understand the main characteristics of the underlying merging system in order to predict the expected GW signal. Based on numerical-relativity simulations of merging neutron star binaries, the emitted GW and the interior structure of the generated hypermassive neutron stars (HMNS) have been analyzed in detail. This article will focus on the internal and rotational HMNS properties and their connection with the emitted GW signal. Especially, the appearance of the hadon-quark phase transition in the interior region of the HMNS and its conjunction with the spectral properties of the emitted GW will be addressed and confronted with the simulation results of high energy heavy ion collisions.

  18. Plutonium roundtable discussion

    Penneman, R.A.


    The roundtable discussion began with remarks by the chairman who pointed out the complicated nature of plutonium chemistry. Judging from the papers presented at this symposium, he noticed a pattern which indicated to him the result of diminished funding for investigation of basic plutonium chemistry and funding focused on certain problem areas. Dr. G.L. silver pointed to plutonium chemists' erroneous use of a simplified summary equation involving the disproportionation of Pu(EV) and their each of appreciation of alpha coefficients. To his appreciation of alpha coefficients. To his charges, Dr. J.T. Bell spoke in defense of the chemists. This discussion was followed by W.W. Schulz's comments on the need for experimental work to determine solubility data for plutonium in its various oxidation states under geologic repository conditions. Discussion then turned to plutonium pyrachemical process with Dana C. Christensen as the main speaker. This paper presents edited versions of participants' written version

  19. Faraday Discussions meeting Catalysis for Fuels.

    Fischer, Nico; Kondrat, Simon A; Shozi, Mzamo


    Welcome to Africa was the motto when after more than 100 years the flag ship conference series of the Royal Society of Chemistry, the Faraday Discussions was hosted for the first time on the African Continent. Under the fitting topic 'Catalysis for Fuels' over 120 delegates followed the invitation by the conference chair Prof. Graham Hutchings FRS (Cardiff Catalysis Institute), his organizing committee and the co-organizing DST-NRF Centre of Excellence in Catalysis c*change (). In the presentations of 21 invited speakers and 59 posters, cutting edge research in the field of catalysis for fuels, designing new catalysts for synthetic fuels, hydrocarbon conversion in the production of synthetic fuels and novel photocatalysis was presented over the two-day meeting. The scene was set by the opening lecture of Prof. Enrique Iglesias (UC Berkeley) and wrapped-up with the concluding remarks by Philip Gibson (SASOL).

    Using a definition of conditional entropy given by Hanen and Neveu [5, 10, 11] we discuss in this paper some properties of conditional entropy and mean entropy, in particular an integral representation of conditional entropy (§ 2), and the decomposition theorem of the KolmogorovSina¯i invariant (§

  2. Some remarks on modeling uncertainties

    Ronen, Y.


    Several topics related to the question of modeling uncertainties are considered. The first topic is related to the use of the generalized bias operator method for modeling uncertainties. The method is expanded to a more general form of operators. The generalized bias operator is also used in the inverse problem and applied to determine the anisotropic scattering law. The last topic discussed is related to the question of the limit to accuracy and how to establish its value. (orig.) [de

  4. Remarks on finite W algebras

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


    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)

  5. New remarks on chiral bosonization

    Souza Dutra, A. de


    We discuss a certain duality between the constraints appearing in ordinary Lagrangian density and its first order counterpart for the gauged Siegel chiral boson. It is demonstrated the equivalence, at the classical level, of the two versions of the gauged Siegel chiral boson to its corresponding gauged Floreanini-Jackiw chiral bosons. It is also argued that the most general constrained Lagrangian density, that leads to a bosonic field obeying a first order differential equation of motion and preserve simultaneously Lorentz invariance, is just the Floreanini-Jackiw one.

    Billal, Masum


    We dedicate this paper to investigate the most generalized form of Fibonacci Sequence, one of the most studied sections of the mathematical literature. One can notice that, we have discussed even a more general form of the conventional one. Although it seems the topic in the first section has already been covered before, but we present a different proof here. Later I found out that, the auxiliary theorem used in the first section was proven and even generalized further by F. T. Howard. Thanks...

  7. Enlarging the bounds of moral philosophy: Why did Isaac Newton conclude the Opticks the way he did?

    Henry, John


    This paper draws attention to the remarkable closing words of Isaac Newton's Optice (1706) and subsequent editions of the Opticks (1718, 1721), and tries to suggest why Newton chose to conclude his book with a puzzling allusion to his own unpublished conclusions about the history of religion. Newton suggests in this concluding passage that the bounds of moral philosophy will be enlarged as natural philosophy is ‘perfected’. Asking what Newton might have had in mind, the paper first considers the idea that he was foreshadowing the ‘moral Newtonianism’ developed later in the eighteenth century; then it considers the idea that he was perhaps pointing to developments in natural theology. Finally, the paper suggests that Newton wanted to at least signal the importance of attempting to recover the true original religion, and perhaps was hinting at his intention to publish his own extensive research on the history of the Church.

  8. Remark on Trautman's Radiation Condition

    Walker, M.


    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.)

  10. Introductory remarks by Augusto Ancarani

    Ancarani, Augusto


    The subject proposed for the present roundtable is in the form of a twofold question. To assert that advocates and adversaries of nuclear power are listening to each other will hopefully result from what will be said. But, as far as the chance of a dialogue is concerned, one can answer in the positive from the start. Indeed a dialogue is always possible, even among deaf people, provided they are polite. This has been and still is the situation in many instances. If we consider the politics situation in a worldwide perspective, we hove to acknowledge that the mood is favorable to the dialogue on almost every possible subject. If this is true among the great powers, it will also be the case, at all the Levels, inside our democratic and articulate societies, O rice set in motion the solution of the great problems concerning peace among notions, still remain to be tackled the ones about the welfare of humankind. Such welfare rests heavily on the availability of energy; besides, energy cannot bp produced without some consequences upon the environment. This process will bi a Long and a difficult one; it will be exhausted only through confrontations, exchanges of view, dialogues, discussions - any term that you will care to choose

  11. Are the advocates of nuclear power and the adversaries listening to each other? Does Dialogue have a chance? Introductory remarks by John A. Macpherson[Roundtable discussion on whether the advocates of nuclear power and the adversaries are listening to each other

    Macpherson, John A [Atomic Energy of Canada Ltd., Mississauga, ON (Canada)


    Are the advocates of nuclear power and the adversaries listening to each other? Does dialogue have a chance? My short answer to both questions posed as the title for this discussion is 'no'. And I would add: There is no point in trying to bring opposite poles together, it requires too much investment for too little return. A nuclear dialogue will have a chance only it a distinction can be shown between physics and metaphysics, between chemistry and alchemy, and if the gap can be bridged between the polarized views of the world's societal needs which, incidentally, create the nuclear issue in the first place. This is a daunting task Movements in search of a cause have a passion for preaching rather than a love for listening.

    Gibson, B. F.


    These remarks represent the author’s personal perspective regarding ideas presented at this fifth Asia Pacific Conference on Few-Body Problems in Physics. They are not intended as a comprehensive summary of what we witnessed during this week of stimulating presentations and intense discussions. However, these remarks do characterize some of the physics we heard and some of the key questions raised. The ideas presented will hopefully outlive the rapporteurs who brought their work and that of others to our attention here in the International Hall of the Sungkyunkwan University in Seoul, Republic of Korea.

  13. Remarks on theoretical hot-atom chemistry

    Inokuti, Mitio


    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.)

  14. Clear progress in nuclear safety worldwide: Convention on nuclear safety concludes


    It has been concluded that a significant progress has been observed in a number of key areas, such as strengthened legislation, regulatory independence, the availability of financial resources, enhanced emergency preparedness and safety improvements at nuclear power plants built to earlier standards. The objective of the Convention is to achieve and maintain a high level of nuclear safety worldwide. During the two week Review Meeting, parties engaged in a 'peer review' process in which the National Reports from individual States were collectively examined and discussed, with written replies provided to all the questions raised. Clear improvement was noted in the quality of the National Reports, the number of questions and the openness and quality of discussion and answers. The Contracting Parties praised the IAEA's various safety review missions and services, which they use widely to help enhance the effectiveness of their national safety arrangements. Forty-six contracting parties participated at the Review Meeting with over 400 delegates attending, including many heads and senior officers from regulatory bodies and experts from industry. To date, the Convention has been signed by sixty-five States and ratified by fifty-four, representing 428 of the 448 nuclear power reactors worldwide

  15. Opening remarks for a panel discussion on short-term vs long-term procurement

    Courtenay, R.H.


    Long-term contracting in the late 1970's and early 1980's is blamed for some of the inequities that plague the uranium industry today. Utilities are obliged to pay prices far above prevailing levels and relatively low cost producers are forced to shut down while watching less efficient suppliers stay in business thanks to their long term supply agreements. Furthermore, it is argued that long-term contracts have contributed to supply instability by forcing the buildup of surplus inventories and by supporting excess incremental production by suppliers who have a baseload of long-term contracts. The depressed prices resulting from this oversupply are in turn jeopardizing future resource development and damaging supply reliability. In summary, the author's argument is that supply reliability will be greatly enhanced by the assurance of adequate primary supply from traditional sources such as Canada. This will not happen without long-term contracts. This conclusion may not be expected coming from a representative of Canada's largest uranium producer. But the final comment is less self serving. Many of the critics of long term contracts apparently expect a continuing and plentiful supply of East Bloc uranium to the spot market. A further question is to what extent East Bloc suppliers will eventually require long-term contracts in order to maintain production facilitates in economies that are no longer centrally planned, and where there is open competition for capital. Ultimately, reliability of supply from the non-traditional suppliers may also depend on long-term contracts

  16. IAEA concludes follow-up mission to Kashiwazaki-Kariwa nuclear power plant


    Full text: An IAEA follow-up fact-finding mission to the Kashiwazaki-Kariwa nuclear power plant in Japan has concluded from the examination of the plant's key safety areas that there was no significant damage to safety equipment from a strong earthquake last year. 'The first objective of the team has been to confirm that there appears to be no significant damage to the integrity of the plant,' said Phillipe Jamet, whose team was able to view key internal components in the plant inaccessible during their first visit in August last year. The IAEA team's site visit followed three days of open and constructive discussions with Japanese regulatory officials, the plant's operators, and other experts. The mission concluded that significant data about the earthquake has been gathered and efforts to obtain remaining information are underway. Overall interpretation of all the data will still be necessary to reach a full understanding of the 16 July 2007 earthquake and to assess the possibility of future ones. The team recommended an international cooperative effort which could expand on-going Japanese studies and make a contribution to the evolution of international safety standards. Last year's earthquake significantly exceeded the level of seismic activity for which the Kashiwazaki-Kariwa plant, in the coastal prefecture of Niigata, north-west of Tokyo, was designed. The Director General of the IAEA, Mohamed ElBaradei, said today that an international response to the earthquake is appropriate because of its relevance to other nuclear plants worldwide. He welcomed Japan's continued cooperation with the effort. The earthquake also caused fractures on the surface of the site. Before the reactors at the Tokyo Electric Power Company (TEPCO) owned plant started up, between 1985 and 1997, it was acknowledged that geological faults ran deep beneath the site but were considered stable, the team said. Geologists are investigating if surface fractures caused by the earthquake

  17. Empowerment: a conceptual discussion.

    Tengland, Per-Anders


    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

  18. Remarks about the hypothesis of limiting fragmentation

    Chou, T.T.; Yang, C.N.

  19. Remarkable recoveries: research and practice from a patient's perspective.

    Barasch, Marc Ian


    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.

  20. Legislation and patients' rights: some necessary remarks.

    Mujovic-Zornic, Hajrija


    The essence of a patient's rights and legislation framework requires an answer to the question on how legislation can work towards better defining, respecting, protecting and effectiveness of these rights. First, it is necessary to give a short introduction to patients' rights, their definition and different classifications. In the long list of human rights, patients' rights obviously take one of the very important places. Human life and health are the values, which, in comparison with all other human values, are considered as values of the highest rank. Patients' rights represent a legal expression of something, which every person basically and naturally expects from a doctor, medical staff, and from a health care system in general. The subject of the second part of this paper presents the intention, scope and conception of necessary legislation. How should it be considered - in a wider sense or as a special law? Some theoretical and practical questions regarding interaction between medical ethics regulation, confidentiality, and legislation are discussed as well. In the European context there are numerous examples of laws with the specific purpose of protecting patients' rights. Special attention and critical review will be paid to the situation of patients' rights in Serbia. The paper concludes with the point that the role of legislation is evidently important, but the traditional view should be replaced with a new one, due to the reason that modem health law puts the protection of patients' rights on a higher level. De lege lata, the whole system of health law in its diversity (civil, penal and administrative) is characterized by better understanding of rights, duties and legal relations, either through regulation or the protection of patients' rights.

    This contribution comprises two remarks of ecological rather than physiological character. Contrary to Herter (1952), Herreid (1967), and Harmata (1969), I did not examine the temperature preference, or thermopreferendum, of bats under experimental conditions but concluded on it only on grounds of

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

    Jônadas Techio


    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.

  3. Summary of presentations and discussions

    Takeuchi, Mitsuo


    In December 2007, the Forum on Stakeholder Confidence discussed its theme entitled 'Link between research, development and demonstration (RD and D) and stakeholder confidence'. It was remarked that regulators need a technical demonstration to aid in evaluating the safety case. Local stakeholders appreciate the opportunity to visualise technological arrangements. In both cases, demonstration adds to confidence in the feasibility of solutions. Some believe there is an important role for analogues in communication with stakeholders, if handled with integrity. To explore and benchmark current practices, it was decided to hold a topical session at the 9. regular meeting of the FSC on 4 June 2008 regarding the use of analogues for confidence building. The session opened with an introductory presentation by the session rapporteur. This incorporated input provided for the purpose by FSC members in cooperation with their country's representative to the NEA RWMC 'Integration Group on the Safety Case'. Three speakers then presented the various uses of analogues by implementers, regulators and scientists to build their own confidence; a fourth speaker dealt with the experience of using natural analogues in public information. The presentations addressed the use of analogues in the field of geological disposal of high-level waste (HLW) and long-lived intermediate level (ILW-LL) radioactive waste. Then the FSC participants split into two working groups for discussion. The outcome of these discussions was reported in plenary on 6 June 2008 and it was agreed to publish proceedings of the session. The present summary, prepared by the session rapporteur with input from the NEA Secretariat, captures the main points heard in the course of the event. It combines data from the formal presentations and remarks made in discussion. The latter represent viewpoints expressed by a group whose primary focus is not natural analogues but rather stakeholder interests. The summary and viewpoints

    Petersen, Marianne Graves


    The vision of ubiquitous computing is floating into the domain of the household, despite arguments that lessons from design of workplace artefacts cannot be blindly transferred into the domain of the household. This paper discusses why the ideal of unremarkable or ubiquitous computing is too narrow...... with respect to the household. It points out how understanding technology use, is a matter of looking into the process of use and on how the specific context of the home, in several ways, call for technology to be remarkable rather than unremarkable....

  6. Some remarks about large p/sub perpendicular/ spin effects

    Field, R.D.


    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

  9. Economic and legal consequences of concluded apparent legal on national interests in Montenegro

    Vuksanović Draginja


    Full Text Available Concluding contracts on long-term leases of state-owned properties, beaches and bathing grounds should bring about positive economic effects through the payment of lease fees and the construction of tourist complexes, which in turn should be reflected on the development of tourism, and therefore on a better quality of life of citizens. In order to have legal effect, a contract as a legal transaction must be concluded in accordance with positive legal regulations. The respect for the institution of public order is the only condition limiting the fundamental principle of the law of obligations - the freedom of contract (autonomy of will. Through a detailed legal analysis, we want to draw attention to the examples of contracts on long-term leases that are unlawful. It is a particular type of apparent legal transactions (simulated contracts, because in concluding contracts on long-term leases of state-owned property, leases are simulated in public, while the contracts actually contain elements of sales. It is particularly interesting that the lessor in the concluded contracts is a relevant state authority (a ministry, on whose behalf the contract is signed by an authorized representative who had also led the negotiations with foreign investors. The consequences of such contracts negatively influence the economic development, tourism industry, and therefore also the standard of living of citizens.

    Full text: An IAEA-led international team of nuclear safety experts noted good practices and made recommendations to reinforce safety measures during a review of operational safety at France's Chooz Nuclear Power Plant (NPP) that concluded today. The Operational Safety Review Team (OSART) was assembled at the French Government's request. The in-depth review, which began 17 June, focused on aspects essential to the safe operation of the NPP. The team comprised experts from Switzerland, Belgium, Germany, China, India, United Kingdom, Czech Republic, Canada, Hungary and the IAEA. The review covered the areas of management, organization and administration; training and qualification of personnel; operations; maintenance; technical support; operating experience; radiation protection; chemistry; emergency planning and preparedness; and severe accident management. The conclusions of the review are based on the IAEA's Safety Standards. The OSART team identified good plant practices that will be shared with the rest of the nuclear industry for consideration. Examples include: The plant has a professional development programme as part of a joint employment effort shared by the plant and its contractors. This enables trainees to develop professional capability, understand practices and gain experience from other nuclear power plants in terms of work planning and coordination; The plant has built a strong relationship between the on-shift response team of the plant and the local fire brigade to improve firefighting and rescue operations; Self-assessment groups discuss and resolve specific issues within operations, empowering operations personnel to take ownership of improvement programmes; and The plant has improved warnings at entrances to all o range zones , areas of elevated dose rates to which only authorized staff have access. The team identified a number of improvements to operational safety at Chooz NPP. Examples include: The plant should review its process for the

  12. Nuclear Power Remains Important Energy Option for Many Countries, IAEA Ministerial Conference Concludes


    Full text: Nuclear power remains an important option for many countries to improve energy security, provide energy for development and fight climate change, the International Ministerial Conference on Nuclear Power in the 21st Century concluded today. Participants also emphasised the importance of nuclear safety in the future growth of nuclear power, noting that nuclear safety has been strengthened worldwide following the March 2011 accident at TEPCO's Fukushima Daiichi Nuclear Power Station. The Conference was organised by the International Atomic Energy Agency (IAEA) in cooperation with the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-operation and Development (OECD), and hosted by the Government of the Russian Federation through the State Atomic Energy Corporation ROSATOM. Sergei Kirienko, Director General of the State Atomic Energy Corporation ROSATOM, said: ''The Conference has achieved its main goal: to confirm that nuclear energy is an important part of the world's energy-mix. The innovative character of this type of energy provides us with sustainable development in the future. The closed nuclear fuel cycle and fusion may open for humanity absolutely new horizons. The Conference underlined the leading role of the IAEA in promoting the peaceful use of nuclear power and provision of the non-proliferation regime. Russia as a co-founder of the IAEA will always support its efforts to develop and expand safety and security standards all over the world.'' ''I believe we can look ahead with confidence and optimism to the future of nuclear power in the 21st century,'' said IAEA Director General Yukiya Amano. After the accident at the Fukushima Daiichi Nuclear Power Plant in Japan in March 2011, ''effective steps have been taken to make nuclear power plants safer everywhere,'' he stressed. ''Nuclear power will make a significant and growing contribution to sustainable development in the coming decades. The IAEA is committed to ensuring that the

  13. Remarks about the displaced spectra techniques

    Behringer, K.; Pineyro, J.


    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)

  14. IAEA Team Concludes Peer Review of Sweden's Nuclear Regulatory Framework, 17 February 2012, Stockholm, Sweden


    Full text: An international team of senior nuclear safety and radiation protection experts today concluded a 12-day mission to review the regulatory framework for nuclear and radiation safety in Sweden. The Integrated Regulatory Review Service (IRRS) mission, which was conducted at the request of Sweden, noted good practices in the country's nuclear regulatory system and also made recommendations and suggestions for the Swedish Radiation Safety Authority (SSM) and the government. These are aimed at strengthening the effectiveness of the country's regulatory framework and functions in line with IAEA Safety Standards. ''Throughout the mission, the IRRS team received full cooperation from SSM staff in its review of Sweden's regulatory, technical and policy issues,'' said Georg Schwarz, mission leader and Deputy Director General of the Swiss nuclear regulator (ENSI). 'The staff were open and candid in their discussions and provided the fullest practicable assistance', he commented. The main observations of the IRRS Review team included the following: SSM operates as an independent regulator in an open and transparent manner with well-organized regulatory processes; SSM is receptive to feedback and strives to maintain a culture of continuous learning; and Following the TEPCO Fukushima Daiichi accident, SSM responded promptly to public demand for information and communicated effectively with the national government, the public and other interested parties. Good practices identified by the IRRS team included, though they are not limited to, the following: The consolidation of the two previous national regulatory authorities into SSM was successful; Overall, SSM's management system is comprehensive and contributes to staff efficiency and effectiveness; The nuclear power plant refurbishment programme as required by SSM enhanced safety; and Sweden's regulatory framework for high-level waste disposal is comprehensive and technically sound. The IRRS Review team identified

  15. EDITORIAL: Dialog on Science and Policy to Address the Climate Crisis to conclude the International Association of Research Universities Climate Congress, Copenhagen, Denmark Dialog on Science and Policy to Address the Climate Crisis to conclude the International Association of Research Universities Climate Congress, Copenhagen, Denmark

    Baer, Paul; Kammen, Daniel M.


    This is not the usual Editor-in-Chief letter, namely one that focuses on the accomplishments of the journal—and for ERL they have been numerous this year—but a recognition of the critical time that we are now in when it comes to addressing not only global climate change, but also the dialog between science and politics. In recognition of the many 'tipping points' that we now confront—ideally some of them positive social moments—as well as the clear scientific conclusion that environmental tipping points are points of long-lasting disruption, this paper takes a different form than I might have otherwise written. While the scientific body of knowledge around global environmental change mounts, so too, do the hopeful signs that change can happen. The election of Barack Obama is unquestionably one such sign, witnessed by the exceptional interest that his story has brought not only to US politics, but also to global views of the potential of the United States, as well as to the potential role of science and investigation in addressing pressing issues. In light of these inter-related issues, reproduced here—largely due to the efforts of Paul Baer to transcribe a remarkable conversation—is a dialog not only on the science of global warming and the potential set of means to address this issue, but also on the interaction between research, science and the political process. The dialog itself is sufficiently important that I will dispense with the usual discussion of the exciting recognition that ERL has received with an ISI rating (a factor rapidly increasing), the high levels of downloads of our papers (for some articles over 5000 and counting), and the many news and scientific publications picking up ERL articles (in recent days alone Science, Environmental Science and Technology, and The Economist). This conversation was the concluding plenary session of the 10-12 March International Association of Research Universities (IARU) Conference on Climate Change

  16. IAEA Team Concludes Peer Review of Greece's Regulatory Framework for Radiation Safety


    Full text: An international team of senior nuclear safety and radiation protection experts yesterday concluded an 11-day mission to review the regulatory framework for nuclear and radiation safety in Greece. The Integrated Regulatory Review Service (IRRS) mission, which was conducted at the request of the Government of the Hellenic Republic, noted good practices in the country's nuclear regulatory system and also identified issues for improvement for the Greek Atomic Energy Commission (GAEC) and the Greek competent authorities. These are aimed at strengthening the effectiveness of the country's regulatory framework and functions in line with IAEA Safety Standards. ''The IRRS team enjoyed excellent cooperation from the GAEC throughout its mission,'' said Tom Ryan, mission leader and Director of Regulations and Information Management at the Radiological Protection Institute of Ireland. ''The GAEC staff were very open and candid in their discussions and provided the fullest practicable assistance.'' The main observations of the IRRS Review team included: While the Greek Government's commitment to safety is being demonstrated through its actions, the development of a comprehensive national policy and strategy expressed in a consolidated statement would provide a valuable framework and guidance for future actions in terms of safety; and GAEC has effective independence. The Greek government has ensured that GAEC is effectively independent in its safety-related decision-making and that it has functional separation from entities having responsibility or interests that could unduly influence its decision making. Strengths and good practices identified by the IRRS team included: Greece actively participates in the global safety regime including all relevant safety conventions; The nation's radiation monitoring system for the detection of illicit trafficking contributes significantly to identifying potential radiation emergencies due to events within or outside the country

  17. International Nuclear and Radiation Safety Experts Conclude IAEA Peer Review of Slovenia's Regulatory System


    Full text: An international team of senior nuclear safety experts today concluded a 10-day mission to review the regulatory framework for nuclear and radiation safety in Slovenia. The team identified good practices and gave advice on areas for future improvements. The IAEA has conveyed the team's main conclusions to the Government of Slovenia and a final report will be submitted by the end of 2011. At the request of the Slovenian Government, the IAEA assembled a team of 10 senior regulatory experts from nine nations to conduct the Integrated Regulatory Review Service (IRRS) mission involving the Slovenian Nuclear Safety Administration (SNSA). The mission is a peer review based on the IAEA Safety Standards. Andrej Stritar, Director of Slovenian Nuclear Safety Administration, stressed ''how important it is for a small country like Slovenia to tightly follow international standards in the area of nuclear safety.'' He also expressed his gratitude to the IAEA, and the countries from which team members came, for their support and for their intensive work during the last ten days. Mission Team Leader Colin Patchett, Deputy Chief Inspector from the UK's Office for Nuclear Regulation commended ''the Slovenian authorities for their commitment to nuclear and radiation safety regulation and for sharing their experience.'' The IRRS team reviewed Slovenia's current regulatory framework and all SNSA-regulated facilities and activities, as well as the regulatory implications of the TEPCO Fukushima Daiichi accident. The IRRS team identified particular strengths in the Slovenian regulatory system, including: Through its legal framework, the Slovenian government has appointed SNSA to regulate its nuclear safety program and SNSA has in place an effective process for carrying out this responsibility; and Slovenia's response to the accident at the TEPCO Fukushima Daiichi power plant has been prompt and effective. Communications with the public, development of actions for improvement

  18. International Expert Team Concludes IAEA Peer Review of Bulgaria's Regulatory Framework for Nuclear and Radiation Safety


    Full text: An international team of senior nuclear safety and radiation protection experts today concluded a 12-day mission to review the regulatory framework for nuclear and radiation safety in Bulgaria. The Integrated Regulatory Review Service (IRRS) mission, conducted at the request of the Government of Bulgaria, identified a series of good practices and made recommendations to help enhance the overall performance of the regulatory system. IRRS missions, which were initiated in 2006, are peer reviews based on the IAEA Safety Standards; they are not inspections or audits. ''Bulgaria has a clear national policy and strategy for safety, which are well in line with international standards and practices and contribute to a high level of nuclear safety,'' said Mission Team Leader Marta Ziakova, Chairperson of the Nuclear Regulatory Authority of the Slovak Republic. The mission team, which conducted the review from 8 to 19 April, was made up of 16 senior regulatory experts from 16 nations, and six IAEA staff. ''The results of the IRRS mission will be valuable for the future development and reinforcement of the Bulgarian Nuclear Safety Agency (BNRA). The use of international standards and good practices helps to improve global harmonization in all areas of nuclear safety and radiation protection,'' said Sergey Tzotchev, Chairman of the BNRA. Among the main observations in its preliminary report, the IRRS mission team found that BNRA operates as an independent regulatory body and conducts its regulatory processes in an open and transparent manner. In line with the IAEA Action Plan on Nuclear Safety, the mission reviewed the regulatory implications for Bulgaria of the March 2011 accident at TEPCO's Fukushima Daiichi Nuclear Power Station in Japan. It found that the BNRA's response to the lessons learned from that accident was both prompt and effective. Strengths and good practices identified by the IRRS team include the following: A no-blame policy is enshrined in law for

  19. SPECT Myocardial Blood Flow Quantitation Concludes Equivocal Myocardial Perfusion SPECT Studies to Increase Diagnostic Benefits.

    Chen, Lung-Ching; Lin, Chih-Yuan; Chen, Ing-Jou; Ku, Chi-Tai; Chen, Yen-Kung; Hsu, Bailing


    Recently, myocardial blood flow quantitation with dynamic SPECT/CT has been reported to enhance the detection of coronary artery disease in human. This advance has created important clinical applications to coronary artery disease diagnosis and management for areas where myocardial perfusion PET tracers are not available. We present 2 clinical cases that undergone a combined test of 1-day rest/dipyridamole-stress dynamic SPECT and ECG-gated myocardial perfusion SPECT scans using an integrated imaging protocol and demonstrate that flow parameters are capable to conclude equivocal myocardial perfusion SPECT studies, therefore increasing diagnostic benefits to add value in making clinical decisions.

  20. The end of a remarkable era


    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...

  2. Discussion in Postsecondary Classrooms

    Curt Dudley-Marling


    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

  3. Some remarks on the design of HIF current multiplication rings

    Reich, K.H.


    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.

  4. HM Sagittae - a most remarkable star

    Kwok, S.


    The author summarises recent observations of HM Sagittae, a symbiotic star that displays activity in every spectral band from X-ray to radio. He concludes that it is best described as a binary system consisting of a late M giant and a hot compact object which is similar to central stars of planetary nebulae. The presence of a wind from the M giant implies that Roche-lobe overflow is not a necessary condition for mass transfer. The complex structure of the circumstellar nebula is possibly the result of wind interactions. The ongoing spectral evolution of HM Sge after its recent outburst makes it an ideal candidate to test models of the symbiotic phenomenon. (Auth.)

  5. Statement on current progress of the EPR project. Basic Design phase concluded

    Lamprecht, F.


    Against the background of expected increasing demand for electric power worldwide it is obvious that any existing technology for electricity generation will be required in the future to meet the demand, just as well as technology improvements. Nuclear industry's answer to this challenge are activities for further evolution of the PWR concept as a joint venture of France and Germany for development of the European Pressurized Water Reactor (EPR). The project participants are reactor manufacturers and operators of both countries as well as organisations responsible for reactor safety. The Basic Design phase which started in 1995, after prior definition of the common safety philosophy, has recently been concluded. The results have been presented at a meeting in October 1997 in Cologne, organised by KTG and SFEN, the countries' respective nuclear societies. The broad statement is that project work was successful in achieving two major objectives: A well-balanced safety concept, and a competitive design. (orig./CB) [de

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

    Morrissey, Michael B; Hadfield, Jarrod D


    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).

  7. Encouraging Classroom Discussion

    Robert Joseph McKee


    Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

  15. Concluding comments: maximizing good patient care and minimizing potential liability when considering complementary and alternative medicine.

    Gilmour, Joan; Harrison, Christine; Vohra, Sunita


    Our goal for this supplemental issue of Pediatrics was to consider what practitioners, parents, patients, institutions, and policy-makers need to take into account to make good decisions about using complementary and alternative medicine (CAM) to treat children and to develop guidelines for appropriate use. We began by explaining underlying concepts and principles in ethical, legal, and clinical reasoning and then used case scenarios to explore how they apply and identify gaps that remain in practice and policy. In this concluding article, we review our major findings, summarize our recommendations, and suggest further research. We focus on several key areas: practitioner and patient/parent relationships; decision-making; dispute resolution; standards of practice; hospital/health facility policies; patient safety; education; and research. Ethical principles, standards, and rules applicable when making decisions about conventional care for children apply to decision-making about CAM as well. The same is true of legal reasoning. Although CAM use has seldom led to litigation, general legal principles relied on in cases involving conventional medical care provide the starting point for analysis. Similarly, with respect to clinical decision-making, clinicians are guided by clinical judgment and the best interests of their patient. Whether a therapy is CAM or conventional, clinicians must weigh the relative risks and benefits of therapeutic options and take into account their patient's values, beliefs, and preferences. Consequently, many of our observations apply to conventional and CAM care and to both adult and pediatric patients.

  16. The wide range in-core neutron measurement system used in the Windscale AGR concluding experiments

    Goodings, A.; Budd, J.; Wilson, I.


    The Windscale AGR Concluding Experiments included a comparison of theoretical and experimental power transients and required measurements of neutron flux as a function of position and time within the reactor core. These measurements were specified to cover as wide as possible working range and had to be made against the in-core gamma background of up to 4 x 10 7 R(hr) - 1 . The detectors were required to operate in special, channels cooled by reactor inlet carbon dioxide and the overall system needed a response time such that it could follow transients with doubling times down to 2s with an accuracy of 2 or 3%. These problems were solved by the use of gas ion fission chambers operating in the current fluctuation or Campbelling mode with unusually low filling pressures and fitted with special trilaminax mineral insulated cables. Ten detectors were built and nine were installed in the reactor, three in each of three special stringers at different radial positions. The paper describes the specification against which this system was built, the design process for the detectors, and commissioning experiments together with some of the problems which were encountered.

  17. Prepared remarks of Martin L. Allday

    Allday, M.L.


    This paper discusses the need for removing needless regulatory obstacles to natural gas industry which prevents competitiveness with other energy sources. The author presents three points which he believes will help reach this goal. The first point is to remove all regulatory pricing controls on wellhead prices. The second point is the development of a good distribution system, especially pipelines, which can quickly respond to serve new or emerging market areas. Finally, the author promotes pipeline rates that promote efficiency, allow for reasonable stability in long-term delivery, and send the right signals to the construction industry. The paper goes on to discuss the deregulation needed to promote pipeline construction activities and allow for transportation of natural gas to become competitive among the various transportation sectors

  1. Chandra Sees Remarkable Eclipse of Black Hole


    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.

  3. IAEA Mission Concludes Peer Review of Viet Nam's Radiation and Nuclear Regulatory Framework


    Senior international nuclear safety and radiation protection experts today concluded a 10-day International Atomic Energy Agency (IAEA) mission to review how Viet Nam's regulatory framework for nuclear and radiation safety has incorporated recommendations and suggestions from an earlier review, conducted in 2009. The Integrated Regulatory Review Service (IRRS) follow-up mission, requested by the Viet Nam Agency for Radiation and Nuclear Safety (VARANS), also reviewed the development of the regulatory safety infrastructure to support Viet Nam's nuclear power programme. The eight-member team comprised senior regulatory experts from Canada, France, Pakistan, Slovenia, United Arab Emirates and the United States of America, as well as three IAEA staff members. The IRRS team said in its preliminary assessment that Viet Nam had made progress since 2009, but that some key recommendations still needed to be addressed. Particular strengths identified by the team included: The commitment of VARANS staff to develop legislation and regulations in the field of nuclear and radiation safety; VARANS' efforts to implement practices that are in line with IAEA Safety Standards and internationally recognized good practices; A willingness to receive feedback regarding the efforts to establish and implement a regulation programme; and Progress made in developing the regulatory framework to support the introduction of nuclear power. The team identified the following areas as high-priority steps to further strengthen radiation and nuclear safety in Viet Nam: The effective independence of the regulatory decision-making process needs to be urgently addressed; Additional resources are needed to regulate existing radiation facilities and activities, as well as the country's research reactor; Efforts to increase the capacity of VARANS to regulate the developing nuclear power programme should continue; The draft Master Plan for the Development of Nuclear Power Infrastructure should be finalized

  4. The wide range in-core neutron measurement system used in the Windscale AGR concluding experiments

    Goodings, A.; Budd, J.; Wilson, I.


    The Windscale AGR concluding experiments included a comparison of theoretical and experimental power transients and required measurements of neutron flux as a function of position and time within the reactor core. These measurements were specified to cover a working range as wide as possible and had to be made against the in-core gamma background of up to 4 x 10 7 R(hr) - 1 . The detectors were required to operate in special channels cooled by reactor inlet CO 2 and the overall system needed a response time such that it could follow transients with doubling times down to 2s with an accuracy of 2 or 3%. These problems were solved by the use of gas ion fission chambers operating in the current fluctuation or ''Campbelling'' mode. Their neutron to gamma sensitivity ratio was optimised by the use of unusually low filling pressures and they were fitted with special ''trilaminax'' mineral insulated cables to minimise the effects of electrical interference at the 100 kHz channel centre frequency. Ten detectors were built and nine were installed in the reactor, three in each of three special stringers at different radial positions. All were processed and tested for operation at 350 deg. C and their fissile coatings (430 μg cm - 1 of natural uranium) were matched to give individual neutron sensitivities with a population spread better than +- 6% about the mean. The mean absolute sensitivities were determined to about +- 5% against manganese foils in the NESTOR reactor at AEE Winfrith. The detectors were complemented by special signal processing channels which provided current fluctuation sensitivity and appropriate output signals to the experiment data acquisition system. These channels also permitted dc measurement of chamber current for more precise flux determination near reactor full power

  6. Some remarks on quasi-Hermitian operators

    Antoine, Jean-Pierre, E-mail: [Institut de Recherche en Mathématique et Physique, Université Catholique de Louvain, B-1348 Louvain-la-Neuve (Belgium); Trapani, Camillo, E-mail: [Dipartimento di Matematica e Informatica, Università di Palermo, I-90123, Palermo (Italy)


    A quasi-Hermitian operator is an operator that is similar to its adjoint in some sense, via a metric operator, i.e., a strictly positive self-adjoint operator. Whereas those metric operators are in general assumed to be bounded, we analyze the structure generated by unbounded metric operators in a Hilbert space. Following our previous work, we introduce several generalizations of the notion of similarity between operators. Then we explore systematically the various types of quasi-Hermitian operators, bounded or not. Finally, we discuss their application in the so-called pseudo-Hermitian quantum mechanics.

  7. Remarks on twisted noncommutative quantum field theory

    Zahn, J. [Hamburg Univ. (Germany). 2. Inst. fuer Theoretische Physik


    We review recent results on twisted noncommutative quantum field theory by embedding it into a general framework for the quantization of systems with a twisted symmetry. We discuss commutation relations in this setting and show that the twisted structure is so rigid that it is hard to derive any predictions, unless one gives up general principles of quantum theory. It is also shown that the twisted structure is not responsible for the presence or absence of UV/IR-mixing, as claimed in the literature. (Orig.)

  8. Remarks on the quantization of conformal fields

    Bakas, I.


    The quantization of a general (b,c) system in two dimensions is formulated in terms of an infinite hierarchy of modules for the Virasoro algebra that interpolate between the space of classical conformal fields of weight j and the Dirac sea of semi-infinite forms. This provides a natural framework in which to study the relation between algebraic geometry and representations of the Virasoro algebra with central charge c j = -2(6j 2 -6j+1). The importance of the construction is discussed in the context of string theory. (orig.)

  9. Some remarks on unilateral matrix equations

    Cerchiai, Bianca L.; Zumino, Bruno


    We briefly review the results of our paper LBNL-46775: We study certain solutions of left-unilateral matrix equations. These are algebraic equations where the coefficients and the unknown are square matrices of the same order, or, more abstractly, elements of an associative, but possibly noncommutative algebra, and all coefficients are on the left. Recently such equations have appeared in a discussion of generalized Born-Infeld theories. In particular, two equations, their perturbative solutions and the relation between them are studied, applying a unified approach based on the generalized Bezout theorem for matrix polynomials

  10. Supersimplicity: a Remarkable High Energy SUSY Property

    Gounaris, G.J.; Renard, F.M.


    It is known that for any 2-to-2 process in MSSM, only the helicity conserving (HC) amplitudes survive asymptotically. Studying many such processes, at the 1-loop Electroweak (EW) order, it is found that their high energy HC amplitudes are determined by just three forms: a log-squared function of the ratio of two of the (s, t, u) variables, to which a π 2 is added; and two Sudakov-like ln- and ln 2 -terms accompanied by respective mass-dependent constants. Apart from a possible additional residual constant (which is also discussed), these HC amplitudes, may be expressed as linear combinations of the above three forms, with coefficients being rational functions of the (s, t, u) variables. This 1-loop property, called supersimplicity, is of course claimed for the 2-to-2 processes considered; but no violating examples are known at present. For ug → dW, supersimplicity is found to be a very good approximation at LHC energies, provided the SUSY scale is not too high. SM processes are also discussed, and their differences are explored.

  11. Some remarks about engineering factor determination

    Svarny, J.


    The problem of the power distribution uncertainties is in general a multidimensional problem of random vector and problem of multidimensional Probability Density Function. The standard methodology of derivation WWER engineering factors is based on representation of analyzed power peaking in the linear form of random factors and on presumption about their normal Probability Density Function. In this paper is presented the derivation of locally defined engineering factors and for mechanical factors has been performed their reformulation. Final formulation of engineering factors as a statistics of relative deviations involves new parameter-mean. Engineering factors definition from so called endpoints of uncertainty tolerance interval is recommended. Approach (95%/95%) for normal Probability Density Function is discussed in detail, the relation to present standard uncertainty methodology of power distribution is found and problem of optimality in tolerance factor finding including limitation of sample size is discussed. On the bases of statistically based uncertainty kinf analysis for linear model has been shown that multivariate outputs vector of power peaking has nearly normal Probability Density Function independently on the Probability Density Function character of input multivariate vector from under its small dimension (lower than number of fuel assemblies in 1/6 core symmetry). Finally the development of the methodological part of the engineering factors for WWER-1000 design macrocode MOBY-DICK is described and their calculation direct on the bases of self-powered detector experimental data of Temelin NPP and Volgodonsk NPP has been performed with inclusion the variability of detector (self-powered detector).

  12. International Nuclear Safety Experts Conclude IAEA Peer Review of Korea's Regulatory System


    Full text: An international team of senior nuclear safety experts concluded today a two-week mission to review the regulatory framework for nuclear safety in the Republic of Korea. The team identified good practices and gave advice on areas for future improvements. The IAEA has conveyed the team's main conclusions to the Government of Korea, while the final report will be submitted by the end of summer 2011. At the request of the Korean Government, the IAEA assembled a team of 16 senior regulatory experts from 14 nations to conduct the Integrated Regulatory Review Service (IRRS) mission involving the Korean Ministry for Education, Science and Technology (MEST) and the Korean Institute for Nuclear Safety (KINS). The mission is a peer-review based on the IAEA Safety Standards. ''This was the first IRRS mission organized after Japan's Fukushima Daiichi nuclear accident and it included a review of the regulatory implications of that event,' explains Denis Flory, IAEA Deputy Director General and Head of the Department of Nuclear Safety and Security. William Borchardt, Executive Director of Operations from the US Nuclear Regulatory Commission and Team Leader of this mission commended the Korean authorities for their openness and commitment to sharing their experience with the world's nuclear safety community. ''IRRS missions such as the one that was just concluded here in the Republic of Korea are crucial to the enhancement of nuclear safety worldwide,'' he said. The IRRS team reviewed Korea's current regulatory framework while acknowledging the fact that the country's Government has already decided to establish, as of October 2011, a new independent regulatory body to be called Nuclear Safety Commission (NSC). As a consequence, KINS role will be as a regulatory expert organization reporting to the NSC, while MEST's role will be restricted to promoting the utilization of nuclear energy. The IRRS team identified particular strengths in the Korean regulatory system

  13. Summary of group discussions


    A key aspect of the workshop was the interaction and exchange of ideas and information among the 40 participants. To facilitate this activity the workshop participants were divided into five discussions groups. These groups reviewed selected subjects and reported back to the main body with summaries of their considerations. Over the 3 days the 5 discussion groups were requested to focus on the following subjects: the characteristics and capabilities of 'good' organisations; how to ensure sufficient resources; how to ensure competence within the organisation; how to demonstrate organisational suitability; the regulatory oversight processes - including their strengths and weaknesses. A list of the related questions that were provided to the discussion groups can be found in Appendix 3. Also included in Appendix 3 are copies of the slides the groups prepared that summarised their considerations

    Hennink, Monique M


    The Understanding Research series focuses on the process of writing up social research. The series is broken down into three categories: Understanding Statistics, Understanding Measurement, and Understanding Qualitative Research. The books provide researchers with guides to understanding, writing, and evaluating social research. Each volume demonstrates how research should be represented, including how to write up the methodology as well as the research findings. Each volume also reviews how to appropriately evaluate published research. Focus Group Discussions addresses the challenges associated with conducting and writing focus group research. It provides detailed guidance on the practical and theoretical considerations in conducting focus group discussions including: designing the discussion guide, recruiting participants, training a field team, moderating techniques and ethical considerations. Monique Hennink describes how a methodology section is read and evaluated by others, such as journal reviewers or ...

  15. Theological remarks on the Accra Confession

    Hans-Wilfried Haase


    Full Text Available This article provides a critical evaluation of the Accra Confession (WARC 2004. The misery in various regions of the southern hemisphere poses an extreme ethical challenge for the Christian faith; the outcry for justice should not be left unheeded. It is necessary that the causes of this misery should be clearly described before viable strategies for overcoming it can be developed. The Accra Confession seems to be rather one-dimensional in its evaluation of reality. The ethical charge implied by the term ‘confession’ is of little use when dealing with complex global fields of action that only rarely allow a simple equation of cause and reaction. It is not so much a ‘confession’ (or Bekenntnis that is needed but rather a renewed discussion among all concerned on the best ways to achieve more justice.

  16. Remarks on crack-bridging concepts

    Bao, G.; Suo, Z.


    The article draws upon recent work by us and our colleagues on metal and ceramic matrix composites for high temperature engines. The central theme here is to deduce mechanical properties, such as toughness, strength and notch-ductility, from bridging laws that characterize inelastic processes associated with fracture. A particular set of normalization is introduced to present the design charts, segregating the roles played by the shape, and the scale, of a bridging law. A single material length, γ 0 E/σ 0 , emerges, where γ 0 is the limiting-separation, σ 0 the bridging-strength, and E the Young's modulus of the solid. It is the huge variation of this length-from a few manometers for atomic bond, to a meter for cross-over fibers - that underlies the richness in material behaviors. Under small-scale bridging conditions, γ 0 E/σ 0 is the only basic length scale in the mechanics problem and represents, with a pre-factor about 0.4, the bridging zone size. A catalog of small-scale bridging solutions is compiled for idealized bridging laws. Large-scale bridging introduces a dimensionless group, a/(γ 0 E/σ 0 ), where a is a length characterizing the component. The group plays a major role in all phenomena associated with bridging, and provides a focus of discussion in this article. For example, it quantifies the bridging scale when a is the unbridged crack length, and notch-sensitivity when a is hole radius. The difference and the connection between Irwin's fracture mechanics and crack bridging concepts are discussed. It is demonstrated that fracture toughness and resistance curve are meaningful only when small-scale bridging conditions prevail, and therefore of limited use in design with composites. Many other mechanical properties of composites, such as strength and notch-sensitivity, can be simulated by invoking large-scale bridging concepts. 37 refs., 21 figs., 3 tabs

  17. Concluding Statement to IAEA Ministerial Conference on Nuclear Safety, 24 June 2011, Vienna, Austria

    Amano, Y.


    must be translated into action - and it will be. This will require hard work from all Member States, and from the IAEA, in the years ahead. This week's deliberations will give me valuable guidance as I prepare the Action Plan on the way ahead, which will be submitted to the IAEA Board of Governors and General Conference in September. Important meetings on nuclear safety are already planned in the next 18 months. The primary goal is to make nuclear power plants as safe as humanly possible, as quickly as possible. But it is also important to rebuild long-term public confidence in the safety of nuclear power. For that, tangible outcomes are needed, and we must maintain our sense of urgency. We must also be fully transparent. I have been in touch with the Commission on Safety Standards to suggest that it begin reviewing IAEA standards on the basis of the views expressed by Member States this week. Likewise, I am inviting the INES Advisory Committee to consider ways of making the International Nuclear and Radiological Event Scale more effective as a communication and information tool. We will also press ahead with detailed proposals in other areas for which we have direct responsibility, such as implementing an expanded programme of expert peer reviews. I would like to conclude by thanking you once again for making this Ministerial Conference a success, for your support for the work of the IAEA and for your guidance. I am confident that, as a result of your work here this week, measurable and lasting improvements will be made in the safety of all nuclear power plants throughout the world. Thank you. (IAEA)

  18. International Expert Team Concludes IAEA Peer Review of Poland's Regulatory Framework for Nuclear and Radiation Safety


    Full text: International safety experts last week concluded a two-week International Atomic Energy Agency (IAEA) mission to review the regulatory framework for nuclear and radiation safety in Poland. In its preliminary report, the Integrated Regulatory Review Service (IRRS) mission team found that Poland's nuclear regulator, Panstwowa Agencja Atomistyki (PAA), has a clear commitment to safety, a high level of transparency, competent staff and leadership, and a good recognition of challenges ahead related to Poland's efforts to develop nuclear power. ''Poland's regulatory framework and the work of PAA give high confidence of strong radiation protection for the Polish people. Further, there has been significant progress in the development of Poland's regulatory framework in preparation for the challenge of regulating nuclear power,'' said team leader Robert Lewis, a senior executive in the US Nuclear Regulatory Commission. The mission was conducted at the request of the Government of Poland from 15-25 April. The team was made up of 11 regulatory experts from Belgium, the Czech Republic, Finland, France, the Republic of Korea, Slovakia, Slovenia, Sweden, the United Arab Emirates, the United Kingdom and the United States, as well as five IAEA staff members. The IRRS review team was very thorough in its review, and we welcome its advice on how to continue to improve our programmes to protect people and the environment , said Janusz Wlodarski, President of PAA. The team interviewed members of PAA and officials from various ministries, as well as key players in the Polish safety framework. Such IRRS missions are peer reviews based on IAEA Safety Standards, not inspections or audits. Among its main observations the IRRS review team identified the following good practices: Applying the considerable experience of PAA's senior management to regulatory issues; The introduction of changes to Poland's laws and regulations following broad public consultation at an early stage in

  6. Several remarks on the fuel cycle economy

    Roman Kubin; Rudolf Vespalec


    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)

  7. Remarks on determinants and the classical polynomials

    Henning, J.J.; Kranold, H.U.; Louw, D.F.B.


    As motivation for this formal analysis the problem of Landau damping of Bernstein modes is discussed. It is shown that in the case of a weak but finite constant external magnetic field, the analytical structure of the dispersion relations is of such a nature that longitudinal waves propagating orthogonal to the external magnetic field are also damped, contrary to normal belief. In the treatment of the linearized Vlasov equation it is found convenient to generate certain polynomials by the problem at hand and to explicitly write down expressions for these polynomials. In the course of this study methods are used that relate to elementary but fairly unknown functional relationships between power sums and coefficients of polynomials. These relationships, also called Waring functions, are derived. They are then used in other applications to give explicit expressions for the generalized Laguerre polynomials in terms of determinant functions. The properties of polynomials generated by a wide class of generating functions are investigated. These relationships are also used to obtain explicit forms for the cumulants of a distribution in terms of its moments. It is pointed out that cumulants (or moments, for that matter) do not determine a distribution function

  8. General remarks. Regional revitalization in Fukushima Prefecture

    Fujita, Reiko


    With a focus on the efforts of the Atomic Energy Society of Japan for the accident of TEPCO Fukushima Daiichi Nuclear Power Station, this paper introduces the movement of decommissioning and decontamination, as well as the efforts for regional revitalization. After the accident, the Atomic Energy Society of Japan performed information collection / analysis / evaluation, held a variety of symposiums, listened to the opinions of experts and knowledgeable persons in and out of Japan, discussed the measures for the accident, and expressed its opinions. The investigation committee academically summarized a wide variety of information about the accident, and published a report. In its accident investigation report, it analyzed the underlying factors of the accident, and proposed recommendations of 50 items. It has continued for an additional contribution to complete the decommissioning project. It is disseminating accurate and easy-to-understand information as the standpoints of residents as well as a nuclear expert. It dispatches specialists to 'Decontamination Information Plaza' to continuously carry out the decontamination advisory job. As part of regional revitalization, it has been implementing a support, such as the provision of counselling and accurate information for the decision-making on the returning-home of refugees. Its contents are as follows; (1) provision of information on the decontamination situation of each site, (2) consultation about the health effects of radiation, and (3) dispatch cooperation of lecturers for education of the staff of municipalities.

  9. International Expert Team Concludes IAEA Peer Review of Finland's Regulatory Framework for Nuclear and Radiation Safety


    Full text: International safety experts today concluded a two-week International Atomic Energy Agency (IAEA) mission to review the regulatory framework for nuclear and radiation safety in Finland. In its preliminary report, the Integrated Regulatory Review Service (IRRS) mission team found that the Radiation and Nuclear Safety Authority of Finland (STUK) is a competent and highly credible regulator that is open and transparent and derives great strength from the technical competence of its staff. ''Finland's comprehensive regulatory framework allows STUK to operate in practice as an independent regulatory body,'' said team leader Philippe Jamet, a commissioner of the French regulatory body ASN. The mission was conducted at the request of the Government of Finland from 15-26 October. The team interviewed members of STUK and officials from various ministries, as well as key players in the Finnish safety framework. Such IRRS missions are peer reviews based on IAEA Safety Standards, not inspections or audits. The team was made up of 18 members from Bulgaria, Canada, the Czech Republic, France, Germany, Iceland, Ireland, Romania, the Russian Federation, South Africa, Slovakia, Slovenia, Spain, Sweden, the United Arab Emirates, the United Kingdom and the United States, as well as six IAEA staff members. 'The IRRS mission and preparation for it was a unique occasion that involved the whole organization, provided motivation for improvement of the safety framework in Finland and assists STUK review its mission', said Tero Varjoranta, Director General of STUK. The IRRS team identified a number of good practices and achievements, including: - STUK's excellence in its safety assessment of nuclear power plants and waste repositories, in particular its demonstration that long-term political commitment is a necessity to sustain the creation of a waste repository as well as its regulatory oversight of medical applications of radiation sources; and - STUK's excellent record in

  10. International Expert Team Concludes IAEA Peer Review of Slovakia's Regulatory Framework for Nuclear Safety


    Full text: An international team of senior nuclear safety and radiation protection experts today concluded an 11-day mission to review the regulatory framework for nuclear safety in Slovakia. At the request of the Slovak Government, the IAEA assembled a team of 12 senior regulatory experts from 12 nations to conduct the Integrated Regulatory Review Service (IRRS) mission involving the Nuclear Regulatory Authority of the Slovak Republic (UJD SR). The international experts also met officials from the Public Health Authority of the Slovak Republic (UVZ SR) regarding the regulation of occupational radiation protection in nuclear facilities. The mission is a peer review based on the IAEA Safety Standards. Marta Ziakova, Chairperson of the Nuclear Regulatory Authority of Slovak Republic, declared that ''The IRRS mission has a great value for the future development and orientation of the UJD SR.'' ''Slovakia has established a regulatory framework for nuclear safety which is in line with international standards and practice,'' said Mission Team Leader Andrej Stritar, Director of the Slovenian Nuclear Safety Administration. The main observations of the IRRS Review team included: UJD SR operates with independence and transparency; UJD SR has developed and implemented a systematic training approach to meet its competence needs; and in response to the accident at TEPCO's Fukushima Daiichi Nuclear Power Station, UJD SR has reacted and communicated to interested parties, including the public. The good practices identified by the IRRS Review Team include: UJD SR has a comprehensive and well-formalized strategic approach to informing and consulting interested parties; UJD SR has developed and implemented a structured approach to training and developing its staff; and Detailed legal requirements provide a solid basis for on-site and off-site response in nuclear emergencies coordinated with local authorities. The IRRS Review team identified areas for further improvement and believes

  11. Remarks on some rock neutron parameters

    Czubek, J.A.


    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

    This session presented highlights of the comments of 8 panelists who discussed the issue of contract design. The new electricity market in Ontario has introduced the energy trader, who enters into a contract with the consumer, based on the spot price set by the Independent Electricity Market Operator. Every contract has a fixed price payer as well as floating-price payers. If the floating price for a given amount of energy is higher than the fixed price, then the consumer gets the difference. Confusion, however, arises with the purchase of retail physical power in the market, particularly in deciding a fixed rate that the consumer will be paying. Different billing options were also discussed with emphasis on mid to large retail customers that have portfolios in the tens of MW and up to 100 MW or more. figs.

  17. International Nuclear Safety Experts Conclude IAEA Peer Review of Swiss Regulatory Framework


    Full text: A team of international nuclear safety experts today completed a two-week International Atomic Energy Agency (IAEA) review of the regulatory framework for nuclear safety in Switzerland. The Integrated Regulatory Review Service (IRRS) mission noted good practices in the Swiss system and also made recommendations for the nation's nuclear regulatory authority, the Swiss Federal Nuclear Safety Inspectorate (ENSI). ''Our team developed a good impression of the independent Swiss regulator - ENSI - and the team considered that ENSI deserves particular credit for its actions to improve Swiss safety capability following this year's nuclear accident in Japan,'' said IRRS Team Leader Jean-Christophe Niel of France. The mission's scope covered the Swiss nuclear regulatory framework for all types of nuclear-related activities regulated by ENSI. The mission was conducted from 20 November to 2 December, mainly at ENSI headquarters in Brugg. The team held extensive discussions with ENSI staff and visited many Swiss nuclear facilities. IRRS missions are peer reviews, not inspections or audits, and are conducted at the request of host nations. For the Swiss review, the IAEA assembled a team of 19 international experts from 14 countries. The experts came from Belgium, Brazil, the Czech Republic, Finland, France, Germany, Italy, the Republic of Korea, Norway, Russia, Slovakia, Sweden, the United Kingdom, and the United States. ''The findings of the IRRS mission will help us to further improve our work. That is part of our safety culture,'' said ENSI Director General Hans Wanner. ''As Switzerland argued at international nuclear safety meetings this year for a strengthening of the international monitoring of nuclear power, we will take action to fulfil the recommendations.'' The IRRS team highlighted several good practices of the Swiss regulatory system, including the following: ENSI requires Swiss nuclear operators to back-fit their facilities by continuously upgrading

  18. Panel discussion: Nuclear cardiology

    Schwaiger, M.


    The panel discussion opened with a question concerning whether true quantification of myocardial sympathetic presynaptic function or receptor density can be obtained with currently available radiopharmaceuticals. What are the relative advantages of the two general approaches that have been proposed for quantification: (1) The assessment of tracer distribution volume in tissue following bolus injection and (2) quantification based on tracer displacement kinetics following administration of excess unlabeled tracer. It was pointed out that tracer kinetics for the delineation of presynaptic and postsynaptic binding sites by radiopharmaceuticals or radiolabeled receptor antagonists are rather complex, reflecting several physiologic processes that are difficult to separate. Several approaches were examined. The possibility of regional definition of receptor density by PET was questioned and it was noted that regions of interest can be applied to calculate regional receptor kinetics. However, due to the limited spatial resolution of PET, only average transmural values can be determined. The discussion then turned to the discrepancy between the known sparse parasympathetic innervation of the heart and the high density of muscarinic receptors observed with PET. Experiences with MIBG imaging were reported, including uptake in the transplanted heart and interaction of drugs with MIBG uptake

  19. Opening Remarks: SciDAC 2007

    Strayer, Michael


    Good morning. Welcome to Boston, the home of the Red Sox, Celtics and Bruins, baked beans, tea parties, Robert Parker, and SciDAC 2007. A year ago I stood before you to share the legacy of the first SciDAC program and identify the challenges that we must address on the road to petascale computing—a road E E Cummins described as `. . . never traveled, gladly beyond any experience.' Today, I want to explore the preparations for the rapidly approaching extreme scale (X-scale) generation. These preparations are the first step propelling us along the road of burgeoning scientific discovery enabled by the application of X- scale computing. We look to petascale computing and beyond to open up a world of discovery that cuts across scientific fields and leads us to a greater understanding of not only our world, but our universe. As part of the President's America Competitiveness Initiative, the ASCR Office has been preparing a ten year vision for computing. As part of this planning the LBNL together with ORNL and ANL hosted three town hall meetings on Simulation and Modeling at the Exascale for Energy, Ecological Sustainability and Global Security (E3). The proposed E3 initiative is organized around four programmatic themes: Engaging our top scientists, engineers, computer scientists and applied mathematicians; investing in pioneering large-scale science; developing scalable analysis algorithms, and storage architectures to accelerate discovery; and accelerating the build-out and future development of the DOE open computing facilities. It is clear that we have only just started down the path to extreme scale computing. Plan to attend Thursday's session on the out-briefing and discussion of these meetings. The road to the petascale has been at best rocky. In FY07, the continuing resolution provided 12% less money for Advanced Scientific Computing than either the President, the Senate, or the House. As a consequence, many of you had to absorb a no cost extension for your

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

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


    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

  5. Fuel ethanol discussion paper


    In recognition of the potential benefits of ethanol and the merits of encouraging value-added agricultural development, a committee was formed to develop options for the role of the Ontario Ministry of Agriculture and Food in the further development of the ethanol industry in Ontario. A consultation with interested parties produced a discussion paper which begins with an outline of the role of ethanol as an alternative fuel. Ethanol issues which require industry consideration are presented, including the function of ethanol as a gasoline oxygenate or octane enhancer, environmental impacts, energy impacts, agricultural impacts, trade and fiscal implications, and regulation. The ethanol industry and distribution systems in Ontario are then described. The current industry consists of one ethanol plant and over 30 retail stations. The key issue for expanding the industry is the economics of producing ethanol. At present, production of ethanol in the short term depends on tax incentives amounting to 23.2 cents/l. In the longer term, a significant reduction in feedstock costs and a significant improvement in processing technology, or equally significant gasoline price increases, will be needed to create a sustainable ethanol industry that does not need incentives. Possible roles for the Ministry are identified, such as support for ethanol research and development, financial support for construction of ethanol plants, and active encouragement of market demand for ethanol-blended gasolines

  2. Accountability for the human right to health through treaty monitoring: Human rights treaty bodies and the influence of concluding observations.

    Meier, Benjamin Mason; De Milliano, Marlous; Chakrabarti, Averi; Kim, Yuna


    Employing novel coding methods to evaluate human rights monitoring, this article examines the influence of United Nations (UN) treaty bodies on national implementation of the human right to health. The advancement of the right to health in the UN human rights system has shifted over the past 20 years from the development of norms under international law to the implementation of those norms through national policy. Facilitating accountability for this rights-based policy implementation under the right to health, the UN Committee on Economic, Social and Cultural Rights (CESCR) monitors state implementation by reviewing periodic reports from state parties, engaging in formal sessions of 'constructive dialogue' with state representatives, and issuing concluding observations for state response. These concluding observations recognise the positive steps taken by states and highlight the principal areas of CESCR concern, providing recommendations for implementing human rights and detailing issues to be addressed in the next state report. Through analytic coding of the normative indicators of the right to health in both state reports and concluding observations, this article provides an empirical basis to understand the policy effects of the CESCR monitoring process on state implementation of the right to health.

    Fano, U.


    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

  4. A remark on the energy conditions for Hawking's area theorem

    Lesourd, Martin


    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.

    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.

  7. Concluding statement by the President of the Conference [International Ministerial Conference on Nuclear Energy in the 21st Century

    Li Yizhong


    develop and maintain appropriate effective physical protection measures, with due regard to IAEA guidance. To this end, international cooperation and communication on nuclear safety and security should be encouraged. -Consideration should be given to measures that will help to ensure reliable access to nuclear fuel supply, while maintaining the normal operation of the international nuclear fuel market. The international community should conduct in-depth discussions and thorough analysis of the technical, legal, political and economic aspects of proposals to establish multilateral nuclear fuel cycle mechanisms for reliable access to nuclear fuel cycle services under the auspices of IAEA. The Director General of the IAEA expressed his hope to bring proposals to the June Board. -The safe management of spent fuel, which for some countries includes reprocessing and recycling, as well as the disposal of radioactive waste are of great importance for the sustainable development of nuclear power. Each State remains responsible for the management of its spent fuel and radioactive waste. The participants encourage international cooperation in these fields. Each State should take appropriate steps to ensure that adequate financial resources are available to support the safety of nuclear installations throughout their life, including during the decommissioning phase, and the safety of the management of spent fuel and radioactive waste. -Countries developing nuclear power programmes are responsible for the development of the necessary infrastructure. Some countries, including developing countries, may seek assistance and support from countries with existing infrastructures and capability. Support should be given to the developing countries to help them to address their particular needs and responsibilities in the development of necessary infrastructures. Specific support could include, inter alia, helping with how to establish laws and regulatory frameworks, supporting training and the

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

  14. Unbound color, prefaced by remarks on baryon spectroscopy

    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

  15. Remarkable rates of lightning strike mortality in Malawi.

    Mulder, Monique Borgerhoff; Msalu, Lameck; Caro, Tim; Salerno, Jonathan


    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.

  18. Nationwide Genomic Study in Denmark Reveals Remarkable Population Homogeneity.

    Athanasiadis, Georgios; Cheng, Jade Y; Vilhjálmsson, Bjarni J; Jørgensen, Frank G; Als, Thomas D; Le Hellard, Stephanie; Espeseth, Thomas; Sullivan, Patrick F; Hultman, Christina M; Kjærgaard, Peter C; Schierup, Mikkel H; Mailund, Thomas


    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.

  1. Discussion of the Porter hypothesis


    In the reaction to the long-range vision of RMNO, published in 1996, The Dutch government posed the question whether a far-going and progressive modernization policy will lead to competitive advantages of high-quality products on partly new markets. Such a question is connected to the so-called Porter hypothesis: 'By stimulating innovation, strict environmental regulations can actually enhance competitiveness', from which statement it can be concluded that environment and economy can work together quite well. A literature study has been carried out in order to determine under which conditions that hypothesis is endorsed in the scientific literature and policy documents. Recommendations are given for further studies. refs

  2. Emotional discussions reduce memory recall.

    Soleti, Emanuela; Wright, Daniel B; Curci, Antonietta


    People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses' discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.

    Rusche, B.C.


    A substantial amount of new generating capacity must be added in the United States before the turn of the century. Noting that the Light Water Reactor (LWR) has enjoyed a remarkably good safety record, the United States Department of Energy (DOE) is working actively to restore public and investor confidence in nuclear power. DOE is working with U.S. industry to encourage licensing reform, simplification and standardization of large plant designs, and resolution of the waste managment issues. We also are pursuing new, more tolerant, lower cost designs and are prepared to share our technology advances with other nations under mutually acceptable conditions and are determined to be a reliable supplier of equipment and enrichment services.

  9. Allotropes of Phosphorus with Remarkable Stability and Intrinsic Piezoelectricity

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


    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.

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

    Hilan Bensusan


    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.

  11. Spectroscopic and asteroseismic analysis of the remarkable main-sequence A star KIC 11145123

    Takada-Hidai, Masahide; Kurtz, Donald W.; Shibahashi, Hiromoto; Murphy, Simon J.; Takata, Masao; Saio, Hideyuki; Sekii, Takashi


    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.

  12. Discussion on Papers 8 - 10

    Full Text Available The article is devoted to the importance of selecting the optimal methods of stimulation and motivation for learning. In modern conditions it is very important that the teacher did not give the students ready knowledge, but pointed out the way for the acquisition of knowledge, taught them to gain knowledge. This demands from the philologist the choice of effective forms of working with texts of different types and styles of speech, listening, speaking. In this connection a special attention should be paid to the lessons of speech development. There is a special group of methods to stimulate the development of communicative competence. Among them, the method of discussion, which is increasingly being used during the Russian language lessons. The specificity of using this method in class for teaching Russian as a foreign language, its basic functions (teaching, developing, educating are considered. The key rules for conducting a discussion at the Russian language classes, the main and additional functions-roles of the teacher, the participants, the minute-taker are analyzed. The advantages of the discussion in Russian in comparison to the discussion in the students’ native language are summarized.

  20. Closing remarks at the symposium in honour of Daniel Bellus. Pharmacenter, University of Basel, February 6, 2009.

    Ganter, Camille


    In the Closing Remarks at the Symposium on 'Frontiers in Bioorganic Chemistry' (Friday, February 6, 2009, Pharmacenter, University of Basel) in honour of Daniel Bellus, his arrival in Zürich in fall 1967 and especially his postdoctoral work at the Laboratorium für Organische Chemie at the Eidgenössische Technische Hochschule (ETH) in Zürich throughout the year 1967/68 were mentioned. In his most remarkable paper (published in 1969 in Helv. Chim. Acta), the photochemistry of the alpha,beta-unsaturated cyclohexenones O-acetyl-testosterone and 10-methy-delta1,9-octalon-(2) is described in detail. Change of solvent leads to lowering or increasing of the n,pi*- and (pi,pi*)-triplet energies, resulting in a crossing of the two energy levels. Personal remarks on Daniel Bellus and warmest thanks to him, to Profs. Beat Ernst and Bernd Giese (the organizers of the symposium) and to all the speakers concluded this most special event.

  1. Comprehension of direct and indirect sarcastic remarks in children and adolescents with Tourette's syndrome.

    Drury, Helena; Shah, Shivani; Stern, Jeremy S; Crawford, Sarah; Channon, Shelley


    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.

  2. The remarkably high excitation planetary nebula GC 6537.

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


    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.

  3. Remarkable reduction of thermal conductivity in phosphorene phononic crystal

    Xu, Wen; Zhang, Gang


    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)

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

    Liliane SANTOS


    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.

  5. Remark on state vector construction when flavor mixing exists

    Fujii, K.; Shimomura, T.


    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

    Charles-Jones, S.; Muirhead, S.; Wilson, E.A.; Jefferson, M.; Binnie, C.J.A.; O'Connor, B.A.; Rothwell, P.; Cowie, D.


    Further observations were made on the great potential for tidal power developments in NW Australia. Discussion on the Severn Barrage paper and environmental effects of tidal power plants centred mainly around the impact on bird populations. The topics covered were: the adaptability of birds to changes in their environment with particular reference to the importance of inter-tidal areas for wildfowl and wading birds in the United Kingdom; the creation of mudflats as replacement feeding areas for wading birds; whether there is a danger that pressure from the construction industry might result in a barrage being built before the uncertainties in the environmental impact assessment are removed. Separate abstracts have been prepared for the three papers under discussion. (UK)

  7. Qualitative discussion of quantitative radiography

    Berger, H.; Motz, J.W.


    Since radiography yields an image that can be easily related to the tested object, it is superior to many nondestructive testing techniques in revealing the size, shape, and location of certain types of discontinuities. The discussion is limited to a description of the radiographic process, examination of some of the quantitative aspects of radiography, and an outline of some of the new ideas emerging in radiography. The advantages of monoenergetic x-ray radiography and neutron radiography are noted

  8. Characterization of remarkable floods in France, a transdisciplinary approach applied on generalized floods of January 1910

    Boudou, Martin; Lang, Michel; Vinet, Freddy; Coeur, Denis


    The 2007 Flood Directive promotes the integration and valorization of historical and significant floods in flood risk management (Flood Directive Text, chapter II, and article 4). Taking into account extreme past floods analysis seems necessary in the mitigation process of vulnerability face to flooding risk. In France, this aspect of the Directive was carried out through the elaboration of Preliminary Flood Risk Assessment (PFRA) and the establishment of a 2000 floods list. From this first list, a sample of 176 floods, considered as remarkable has been selected. These floods were compiled in discussion with local authorities in charge of flood management (Lang et al., 2012) and have to be integrated in priority in local risk management policies. However, a consideration emerges about this classification: how a remarkable flood can be defined? According which criteria can it be considered as remarkable? To answer these questions, a methodology has been established by building an evaluation grid of remarkable floods in France. The primary objective of this grid is to analyze the remarkable flood's characteristics (hydrological and meteorological characteristics, sociological- political and economic impacts), and secondly to propose a classification of significant floods selected in the 2011 PFRA. To elaborate this evaluation grid, several issues had to be taken into account. First, the objective is to allow the comparison of events from various periods. These temporal disparities include the integration of various kinds of data and point out the importance of historical hydrology. It is possible to evaluate accurately the characteristics of recent floods by interpreting quantitative data (for example hydrological records. However, for floods that occurred before the 1960's it is necessary resorting to qualitative information such as written sources is necessary (Coeur, Lang, 2008). In a second part the evaluation grid requires equitable criteria in order not to

  15. Student decision making in large group discussion

    Kustusch, Mary Bridget; Ptak, Corey; Sayre, Eleanor C.; Franklin, Scott V.


    It is increasingly common in physics classes for students to work together to solve problems and perform laboratory experiments. When students work together, they need to negotiate the roles and decision making within the group. We examine how a large group of students negotiates authority as part of their two week summer College Readiness Program at Rochester Institute of Technology. The program is designed to develop metacognitive skills in first generation and Deaf and hard-of-hearing (DHH) STEM undergraduates through cooperative group work, laboratory experimentation, and explicit reflection exercises. On the first full day of the program, the students collaboratively developed a sign for the word ``metacognition'' for which there is not a sign in American Sign Language. This presentation will focus on three aspects of the ensuing discussion: (1) how the instructor communicated expectations about decision making; (2) how the instructor promoted student-driven decision making rather than instructor-driven policy; and (3) one student's shifts in decision making behavior. We conclude by discussing implications of this research for activity-based physics instruction.

  16. Disgust discussed: introduction to the special section.

    Pole, Nnamdi


    The author introduces a special section of Psychological Bulletin devoted to the study of disgust. After discussing conflicts between its supposed role as a basic emotion and its more recently understood involvement in responding to moral transgressions, the author summarizes 3 articles contained in the special section. Widen and Russell (2013) present a developmental account of disgust highlighting the ages at which children experience, express, understand, verbalize, and recognize disgust. The article shows that disgust is present early but that recognition of disgust in others is considerably delayed. Chapman and Anderson (2013) review evidence pertaining to the question of whether genuine disgust is elicited by moral transgressions. Their review covers data from self-report, brain imaging, facial behavior, and implicit measures gathered from both experimental and correlational studies. They conclude that moral transgressions elicit genuine disgust. Russell and Giner-Sorolla (2013) ask what types of moral transgressions are most likely to elicit pure disgust. They find that moral transgressions involving body violations are more likely than others to elicit such disgust. Moreover, they suggest that disgust elicited by body violations is likely to be more resistant to modification by context, situation, and efforts at rationalization. Taken together, the reviews support the view that rudiments of disgust to physical objects are present early in life but later become adapted to social influence and new moral purposes. Social implications are discussed. © 2013 American Psychological Association

  17. Earth Summit Science, policy discussed

    Leath, Audrey T.

    The United Nations Conference on Environment and Development, the “Earth Summit,” convenes in Rio de Janeiro on June 3. President Bush has pledged to attend part of the 2-week conference. The highlight of the summit will be the signing of an international framework convention to reduce emissions of greenhouse gases. The final elements of the agreement were negotiated in New York last week by representative of 143 countries. In anticipation of the Rio conference, the Senate Committee on Energy and Natural Resources held two standing-roomonly hearings, reviewing the scientific basis for global warming due to greenhouse gases and discussing the details of the proposed convention.

  18. Axelrod model: accepting or discussing

    Dybiec, Bartlomiej; Mitarai, Namiko; Sneppen, Kim


    Agents building social systems are characterized by complex states, and interactions among individuals can align their opinions. The Axelrod model describes how local interactions can result in emergence of cultural domains. We propose two variants of the Axelrod model where local consensus is reached either by listening and accepting one of neighbors' opinion or two agents discuss their opinion and achieve an agreement with mixed opinions. We show that the local agreement rule affects the character of the transition between the single culture and the multiculture regimes.

  19. On the Motivation and Foundation of Natural Time Analysis: Useful Remarks

    Varotsos, Panayiotis A.; Sarlis, Nicholas V.; Skordas, Efthimios S.


    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.

  20. Remarks on ''Neutrino masses and mixing angles in a predictive theory of fermion masses''

    Lavoura, L.; Silva, J.P.


    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

  2. Water, food, and population -- a panel discussion.


    This paper summarizes a conference panel discussion among parliamentarians and researchers on water and food supplies and population growth in Asia. The Western Samoa legislator urged delegates to be aware of human development that was no more than the promotion of values associated with a market economy. Samoans increased their per capita caloric consumption. The food supply is provided locally, and 90% of exports are food products. Food security would be jeopardized by a fivefold increase in population. Samoan human development indicators were relatively good for a developing country. However, the country was still ranked as a low-income, food-deficit country. The Pakistani delegate explained that Pakistan's agriculture used the largest, continuous irrigation system in the world. However, the system operated inefficiently. There was concern that future high population growth would jeopardize food security. Another barrier was institutional mismanagement of irrigation and reliance on imports for staple items. Agricultural productivity must increase to meet the increased needs of continued population growth. All available land is currently under cultivation. Future strategies will necessitate international cooperation and innovative and environmentally sound technology. Professor Xuan remarked that increased population growth and rising demand, decreased water quality, and changing consumption patterns were a threat to water supplies. Sustainable increases in food production would entail better water management: reforestation to reduce and prevent water runoff, better technological exploitation of rain water, and more efficient use of irrigation systems. Better international financing schemes were needed for support of these policy changes. Professor Ness suggested free markets in water in order to price water at actual rates of consumption. Polluters should pay. Water management was also threatened by global warming.

  3. Remarkable Women in a Remarkable Age. On the Genesis of the English Public Sphere, 1642-1752

    Eleonora Cappuccilli


    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.

  4. The remarkable cell: Intelligently designed or by evolutionary process?

    Mark Pretorius


    Full Text Available The objective of this article was to deal with the challenging theme of the Origin of Life. Science has been arguing the when and how of the beginning of life for centuries. It is a subject which remains perplexing despite all the technological advances made in science. The first part of the article dealt with the idea of a universe and earth divinely created to sustain life. The second part dealt with the premise that the first life forms were the miraculous work of an intelligent designer, which is revealed by the sophisticated and intricate design of these first life forms. The article concluded with an explanation that these life forms are in stark contrast to the idea of a random Darwinian type evolution for life�s origin, frequently referred to as abiogenesis or spontaneous generation.

  5. A remark on fractional differential equation involving I-function

    Mishra, Jyoti


    The present paper deals with the solution of the fractional differential equation using the Laplace transform operator and its corresponding properties in the fractional calculus; we derive an exact solution of a complex fractional differential equation involving a special function known as I-function. The analysis of the some fractional integral with two parameters is presented using the suggested Theorem 1. In addition, some very useful corollaries are established and their proofs presented in detail. Some obtained exact solutions are depicted to see the effect of each fractional order. Owing to the wider applicability of the I-function, we can conclude that, the obtained results in our work generalize numerous well-known results obtained by specializing the parameters.

    Ikeda, S.


    The gauge fields introduced to accomplish gauge invariance under Poincare and Weyl gauge transformations in general relativity are found a new to be absorbed into the covariant derivative operators. Some torsional properties associated with them are also discussed in connection with the principle of minimally coupling and the equivalence principle

  12. Some remarks on chiral symmetry in dense matter

    Kaellman, C.G.; Montonen, C.


    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.

  17. Summary of the presentations and discussions

    Massaut, Vincent


    The first two presentations were given by specialists in human science, and focused more on the ethical aspects of the funding for decommissioning. Some new aspects or approaches were presented, which allowed to highlight the egalitarian and utilitarian approaches of inter-generational equity. The different ethical principles led to conclude on the need of a democratic debate on the subject, and the need of ethical guidance at international level. Some other key points, like the preservation of competences, funding and resources, were also considered in the light of the inter-generational community. The session was concluded by a presentation on the application of the ethical principles for the funding. Session 2: Actual experience in funding. The various mechanisms for funding have been analyses on their principle, current practice and merits. Three main aspects were analysed: How funds are raised? How are the funds managed? How to disburse when needed? The actual experience in different countries showed different mechanisms and return of experience. Session 3: Uncertainties. In most large industrial projects (construction, civil works, aerospace...), the return of experience shows that overrun (in time and cost) is a rather general tendency. But it depends on the type of project, on the degree of innovation, etc. Some means to avoid these overrun were presented. In the case of D and D, the main uncertainties affecting funding can be found in: cost estimate, inflow of resources, management of resources, time factor: when will the costs occur? Moreover, these uncertainties sources can also be inter-linked. One of the conclusions from this analysis is that the existing uncertainties in funding are good reasons not to postpone decommissioning operations to a too distant future. Presentations on return of experience were presented by several countries. Plenary discussions: The plenary discussions allowed to tackle the different aspects presented during the day. Some

  18. To discuss illicit nuclear trafficking

    Balatsky, Galya I [Los Alamos National Laboratory; Severe, William R [Los Alamos National Laboratory; Wallace, Richard K [Los Alamos National Laboratory


    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

  19. Consultant radiographer leadership - A discussion

    Hogg, Peter; Hogg, Dianne; Henwood, Suzanne


    Effective leadership can be defined in many ways and is an essential element of successful organisations; poor leadership can result in problems such as low staff morale, high staff turnover and reduced productivity. Effective leadership behaviours are well documented in the literature and various leadership models have been proposed that illustrate these behaviours. This discussion paper does not focus on any particular model. Instead it considers the 'Leadership Qualities Framework' which was developed specifically for use within the UK National Health Service. This framework draws upon a range of leadership models and as such it gives a broad indication of leadership behaviours. The framework comprises three components - 'personal qualities', 'setting direction' and 'delivering the service'. This paper commences with an argument as to why effective leadership is important in organisations generally, and specifically within healthcare organisations. Various examples of leadership are illustrated from within and outside the NHS in order to demonstrate effective leadership behaviours. The Leadership Qualities Framework is then examined, along with scenarios to illustrate effective leadership behaviours in context (i.e. within a healthcare organisation). Subsequent reflections on the scenarios aim to identify leadership behaviours that are explained within the framework. The final element of this paper draws on [limited] published evidence of where consultant radiographers have demonstrated effective leadership behaviours. In this section the published evidence is examined and reflected upon. At the end of the article we indicate additional reading for those who wish to further develop their theoretical and practical leadership skills

    Gupton, P


    The metal failure cases discussed by P. Gupton (Monsanto Chem. Co.) at a joint meeting of the American Society of Metals (ASM) and the National Association of Corrosion Engineers Calgary Section (Calgary 1978) include a high-temperature (1775/sup 0/-1800/sup 0/F) failure in an HK 40 outside heater tube in a synthesis gas steam-methane reformer, resulting in two major fissures caused by carbonization and oxide deposits with high carbon and lead contents due to the use of remelt scrap material with high lead content; separation of a support pad from a 30 in. pipeline due to corrosion caused by molybdenum-peroxide action; oxidation of a section of 180/sup 0/ U-bend in a thermal ethylene cracking furnace due to fluxing reaction of a high sodium and calcium feed which collected in the return bed; stress corrosion cracking of an austenitic stainless cracker tube from high temperature and electrolytic attack; and other cases of metal failure caused by weld quality problems, use of contaminated material and inadequate designs, processing, and fabrication.

  1. Emission trading: A discussion paper


    Emission trading is a market-based incentive program designed to control air emissions in which a cap is placed on the total quantity of pollutants allowed to be emitted in an airshed. Appropriate shares of this amount are allocated among participating emission sources, and participants can buy or sell their shares. Advantages of emission trading include its potential to achieve air emission targets at a lower cost than the traditional command and control approach, and its ability to accommodate economic growth without compromising environmental quality. A study was conducted to evaluate the potential use of emission trading programs to achieve emission reduction goals set for nitrogen oxides, volatile organic compounds (VOC), and sulfur oxides. Emission trading programs in the USA are reviewed and a set of factors important for the success of emission trading are identified. Key policy and design issues related to an emission trading program are identified, explained, and discussed. Administrative issues are then analyzed, such as legislative authority, monitoring and enforcement requirements, and trading between jurisdictions. A preliminary assessment of emission trading for control of NOx and VOC in the Lower Fraser Valley indicates that emission trading would be feasible, but legislative authority to implement such a program would have to be introduced

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


    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

  4. Remarks on the classical limit of quantum field theories

    Eckmann, J.P.


    Recently, there has been an increasing interest in computing quantum mechanical corrections to solutions of classical field equations. In this note, proceeding in the opposite way, theorems about the classical limit of relativistic quantum field models are summarized. These results are a byproduct of the so called 'constructive' approach to quantum field theory. Section 1 deals with generalities; in Section 2 the situation where no phase transitions occur is discussed in the limit h→0; and in Section 3 one result in the case where such a transition occurs is reformulated (Glimm et al). The validity of the loop expansion is discussed. It seems however that the tools to show the rigorous validity of soliton calculations are not yet prepared. (Auth.)

  5. Clocking In Turbines: Remarks On Physical Nature And Geometric Requirements

    Swirydczuk Jerzy


    Full Text Available The article discusses two issues relating to the clocking phenomenon in turbines, which are the physical course of stator wake deformation in rotor passages and its further interaction with downstream stator blades, and turbine geometry parameters which are believed to be most favourable for clocking. In both cases, the results presented in the article have made it possible to verify and reformulate the previously accepted opinions.

  6. Remarks to the local power oscillation phenomenon at BWRs

    Lange, Carsten; Hennig, Dieter; Hurtado, Antonio


    In the framework of BWR stability analysis, local neutron-flux oscillation events have attracted the attention of a number of researchers. In 1996, an unusual instability event occurred at Forsmark-1 in which superimposed on the classical, spatial mode oscillations, there were relatively large-amplitude, highly localised oscillations. Subsequent time-series analysis of the local power range monitor (LPRM) signals resulted in a space-dependent decay ratio, an inexplicable result. Furthermore, noise analysis-based localization techniques pointed towards the existence of two strong 'perturbation sources' in the two halves of the core, one of them coinciding with the radial position of an unseated bundle. In the scope of a theoretical work, the possibility of a space-dependent decay ratio was discussed but not comprehensively understood. Motivated by these findings the effect of local neutron-flux oscillations on the BWR stability behaviour is discussed and one possible interpretation is proposed which is able to explain the space dependent decay ratio and the long term oscillation pattern as well. The effect of the local neutron flux oscillating sources on the space and time dependent neutron field is described by a rigorous application of the mode expansion approach. The consequences to signal analysis are then discussed. It will be pointed out in the paper that when a BWR system is stable regarding power oscillations but driven by local neutron-flux oscillating sources, the decay ratio is on the one hand not space-dependent and on the other hand it does not indicate the real BWR stability behaviour. The RAM-ROM method is applied to the Forsmark case M2 and an operational point (KKB-B8) of NPP Brunsbüttel, where a local neutron-flux oscillation is superimposed on an unstable global power oscillation. The results of the bifurcation analysis, using BIFDD, and of the numerical integration are presented for KKB-B8 and Forsmark M2. (author)

  7. Remarks on the ''beginning'' and the ''end'' of the universe

    Deppert, W.


    The concept of time is discussed. If time is defined with physical objects, one is led to the contradiction of eternity with finite duration. It is possible to avoid this contradiction by the introduction of different types of time. The concepts of superspace and ''many-fingered time'' are expressions for the variety of times, and not for the breakdown of the concept of time. With the aid of the distinctions of different well-defined notions of time, knowledge about the time-dependent laws of Nature increases

  8. Some remarks on stochastic collective oscillations in ECRIS plasmas

    Golovanivsky, K.S.


    It is proposed that the thermal fluctuations in plasmas in general and in ECRIS plasmas in particular create rather strong stochastic electrical fields affecting both confinement and heating of an ECRIS plasma. The amplitude, range and characteristic frequency of the stochastic fields as well as the perpendicular diffusion coefficient and the upper density limit for the mirror confinement are determined on the level of the approximate evaluations. Some aspects of the ECRIS plasma's peculiarities due to the stochastic electrical fields are discussed. (author) 7 refs., 5 figs

  9. Remarks on Fermion-Boson equivalence in three dimensions

    Dutra, A. de Souza; Natividade, C.P.


    Starting from a decomposition of the self-dual field in (2+1) dimensions, we build up an alternative quantum theory which consists of a self-dual model coupled to a Maxwell-generalized Chern-Simons theory. We discuss the fermion-boson equivalence of this quantum theory by comparing it to the Thirring model. Using these results we were able to compute the mass of the bosonized fermions up to third order in (1/m). Some problems related to the number of poles of the effective propagator are also addressed.

  10. Some remarks on coherent nonlinear coupling of waves in plasmas

    Wilhelmsson, H.


    The analysis of nonlinear processes in plasma physics has given rise to a basic set of coupled equations. These equations describe the coherent nonlinear evolution of plasma waves. In this paper various possibilities of analysing these equations are discussed and inherent difficulties in the description of nonlinear interactions between different types of waves are pointed out. Specific examples of stimulated excitation of waves are considered. These are the parametric excitation of hybrid resonances in hot magnetized multi-ion component plasma and laser-plasma interactions. (B.D.)

  12. General remarks concerning some laser-initiated fusion proposals

    Wood, L.; Nuckolls, J.; Zimmerman, G.


    The advent of very high power, high energy pulsed laser systems has stimulated considerable thinking regarding how such systems might be used to engender thermonuclear microexplosions, and, in particular, explosions which may produce more energy than the inputted laser energy or even more energy than that used to pump the laser. Some of the basic physical principles and processes constraining laser-CTR proposals will be discussed, and application of them made to establish basic levels of feasibility of these published types of CTR schemes. It is demonstrated that this class of thermonuclear microexplosions has no potential CTR utility with lasers likely to be available in the next few years

  13. Some Remarks on Group Bundles and C* Dynamical Systems

    Vasselli, Ezio


    We introduce the notion of fibred action of a group bundle on a C(X)-algebra. By using such a notion, a characterization in terms of induced C*-bundles is given for C*-dynamical systems such that the relative commutant of the fixed-point C*-algebra is minimal (i.e., it is generated by the centre of the given C*-algebra and the centre of the fixed-point C*-algebra). A class of examples in the setting of the Cuntz algebra is given, and connections with superselection structures with nontrivial centre are discussed.

  14. Remarks at reception for Member States, 9 December 2009, Vienna, Austria

    Amano, Y.


    help to mitigate the impact of global warming. Many Member States have made it clear that they attach great importance to launching new nuclear power programmes, or expanding existing programmes. We have already significantly re-focussed our activities to help meet the needs of newcomers to nuclear power. I plan to build on our achievements and make the assistance we provide in capacity-building and other areas as practical and recipient-friendly as possible. My hope is that, as a result of the Agency's efforts, Member States will start to see tangible progress within four years on the path towards introducing nuclear power. As far as assurances of supply of nuclear fuel are concerned, the Secretariat will facilitate follow-up discussions in light of the recent deliberations in the Board of Governors, with a view to achieving a framework acceptable to all. Enhancing nuclear safety and security will remain indispensable. I will encourage all Member States that have not yet done so to implement all of the relevant safety conventions and codes of conduct. President Obama's decision to host a summit on nuclear security in April highlights the importance of this issue. I am looking forward to attending that meeting. In the area of non-proliferation, I see my role as being to ensure that safeguards agreements are concluded and fully implemented, to provide Member States with factual and objective information and analysis, and to act in accordance with relevant resolutions of the UN Security Council and the Agency's Board of Governors. I trust the Agency will have the full cooperation of all Member States. The bringing into force, and implementation, of additional protocols are of vital importance for the Agency to be able to provide assurances about the exclusively peaceful nature of a country's nuclear programme. I hope we will pass the threshold of 100 additional protocols in force early in my tenure as Director General. The modernisation of our Safeguards Analytical

  15. Remarks on a gauge theory for continuous spin particles

    Rivelles, Victor O. [Universidade de Sao Paulo, Instituto de Fisica, Sao Paulo, SP (Brazil)


    We discuss in a systematic way the gauge theory for a continuous spin particle proposed by Schuster and Toro. We show that it is naturally formulated in a cotangent bundle over Minkowski spacetime where the gauge field depends on the spacetime coordinate x{sup μ} and on a covector η{sub μ}. We discuss how fields can be expanded in η{sub μ} in different ways and how these expansions are related to each other. The field equation has a derivative of a Dirac delta function with support on the η-hyperboloid η{sup 2} + 1 = 0 and we show how it restricts the dynamics of the gauge field to the η-hyperboloid and its first neighbourhood. We then show that on-shell the field carries one single irreducible unitary representation of the Poincare group for a continuous spin particle. We also show how the field can be used to build a set of covariant equations found by Wigner describing the wave function of one-particle states for a continuous spin particle. Finally we show that it is not possible to couple minimally a continuous spin particle to a background abelian gauge field, and we make some comments about the coupling to gravity. (orig.)

  16. Treatment of Bulbar Urethral Strictures. A Review, with Personal Critical Remarks

    Willem Oosterlinck


    Full Text Available This is a review article on treatment of bulbar urethral strictures with personal critical remarks on newer developments. As a treatment of first intention there exists 4 options : dilatation, urethrotomy, end to end anastomosis and free graft, open urethroplasty. Success rate of dilatation and visual urethrotomy after 4 years is only 20 en 40 % respectively. Laser urethrotomy could not fulfill expectations. End to end anastomosis obtains a very high success rate but is only applicable for short strictures. Free graft urethroplasty obtains success rates of ± 80 %. There is considerable debate on the best material for grafting. Buccal mucosa graft is the new wave, but this is not based on scientific data. Whether this graft should be used dorsally or ventrally is also a point of discussion. In view of the good results published with both techniques it is probably of no importance. Intraluminal stents are not indicated for complicated cases and give only good results in those cases which can easily be treated with other techniques. Metal self-retaining urethral stent , resorbable stents and endoscopic urethroplasty is briefly discussed. Redo’s and complicated urethral strictures need often other solutions. Here skin flap from the penile skin and scrotal flap can be used. Advantages and drawbracks of both are discussed. There is still a place for two-stage procedures in complicated redo�s. The two-stage mesh-graft urethroplasty offers advantage over the use of scrotal skin. Some other rare techniques like substitution with bowel and pudendal thigh flap, to cover deep defects, are also discussed.

  17. Review paper Personality and genes: remarks from a biological perspective

    Grzegorz Węgrzyn


    Full Text Available Although there is no doubt that genes’ functions influence human personality, years of studies provided no clear picture on regulation of particular traits by specific genes. In this article, an overview of the complexity of the system of genetic control of personality is presented, and the level of complications of biological processes operating in this system is underlined. The methodology of studies devoted to determine effects of genes on personality traits is discussed, and limitations of various methods in such studies are indicated. Finally, suggestions for further research are listed and commented on. It is likely that to increase the level of our understanding of genetic mechanisms that modulate human personality, researchers conducting further studies will have to focus on using large sample sizes, performing independent replications, considering experiments on animal models, integrating cross-cultural data and epigenetic measures, and performing interdisciplinary experiments which combine methods of various disciplines, such as biology and psychology.

  18. A remark concerning 20 plet dominance in charm decays

    Bigi, Ikaros I


    Based on V spin consideration, it is argued that 20 plet dominance in the effective weak Lagrangian does not strongly reduce the inclusive decay rate of D/sup +/ mesons.

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


    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.

  20. The role of research in nuclear regulation: Opening remarks

    Taylor, J.M.


    More than 20 years ago, the Energy Reorganization Act of 1974 created the USNRC and that same act provided for an office of nuclear regulatory research. It's what is called a statutory office within the NRC. In providing for an NRC research program, our Congress had several things to say about the character of the research that would be performed. First, NRC should perform such research as is necessary for the effective performance of the Commission's licensing and related regulatory functions. Second, the research may be characterized as confirmatory reassessment related to the safe operation and the protection of commercial reactors and other nuclear materials. Third, the NRC should have an independent capability for developing and analyzing technical information related to reactor safety, safeguards, and environmental protection in support of both the licensing and regulatory processes. Fourth, the research should not go beyond the need for confirmatory assessment, because the NRC should never be place in a position of having generated and then having to defend basic design data of its own. This has been and continues to be the role of research at the NRC. Somewhat different purposes might apply for regulatory agencies in other countries. Several regulatory agencies are represented here on this panel, so some of these difference may be discussed

  1. Biomimetics and the case of the remarkable ragworms

    Hesselberg, Thomas


    Biomimetics is a rapidly growing field both as an academic and as an applied discipline. This paper gives a short introduction to the current status of the discipline before it describes three approaches to biomimetics: the mechanism-driven, which is based on the study of a specific mechanism; the focused organism-driven, which is based on the study of one function in a model organism; and the integrative organism-driven approach, where multiple functions of a model organism provide inspiration. The first two are established approaches and include many modern studies and the famous biomimetic discoveries of Velcro and the Lotus-Effect, whereas the last approach is not yet well recognized. The advantages of the integrative organism-driven approach are discussed using the ragworms as a case study. A morphological and locomotory study of these marine polychaetes reveals their biomimetic potential, which includes using their ability to move in slippery substrates as inspiration for novel endoscopes, using their compound setae as models for passive friction structures and using their three gaits, slow crawling, fast crawling, and swimming as well as their rapid burrowing technique to provide inspiration for the design of displacement pumps and multifunctional robots.

  2. Welcome and Opening Remarks of the Technical Plenary

    Chin, S.F.


    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

  3. Toxicological comments to the discussion about REACH.

    Greim, Helmut; Arand, Michael; Autrup, Herman; Bolt, Hermann M; Bridges, James; Dybing, Erik; Glomot, Rémi; Foa, Vito; Schulte-Hermann, Rolf


    It is the ultimate goal of the intended REACH process (Registration, Evaluation and Authorization of Chemicals) of the European Union to identify substances of hazardous properties and to evaluate the risks of human and environmental exposure. During the last few months there has been a controversial discussion as to what extent in vitro studies and consideration of structure activity relationship provide sufficient information to waive repeated exposure studies. Industry as well as certain regulatory agencies or NGOs support this approach and propose that repeated dose studies may only be required beyond 100 t/a. From a toxicological point of view it has to be stressed that this discussion primarily considers the cost reduction and protection of animals, whereas protection of human health and the environment are secondary. In vitro studies only allow identification of specific hazardous properties which can be detected by the specific test system. Moreover, appropriate information on the dose response of adverse effects, identification of thresholds and NOELs that are essential for risk characterization cannot be obtained from these studies. Consequently, identification of all relevant hazardous properties and endpoints of adverse effects can only be determined in the intact animal by repeated dose studies such as 28-day or 90-day studies. In the absence of such information the hazard identification is incomplete and there is no basis for appropriate risk assessment of human exposure. Thus, any waiving of repeated dose studies in animals bears the probability of unforeseen effects in case of acute or continuous human exposure. From this the undersigning European Toxicologists conclude: 1. The intention of REACH is to identify hazardous properties in order that a reliable risk assessment can be made and measures taken to deal with chemicals posing a significant risk. 2. The recent debate has centered on ways in which the well established in vivo methods for risk

  7. Discovery of remarkable subpulse drifting pattern in PSR B0818-41

    Bhattacharyya, B.; Gupta, Y.; Gil, J.; Sendyk, M.

    The study of pulsars showing systematic subpulse drift patterns provides important clues for understanding of pulsar emission mechanism. Pulsars with wide profiles provide extra insights because of the presence of multiple drift bands (e.g PSR B0826-34). We report the discovery of a remarkable subpulse drift pattern in a relatively less studied wide profile pulsar, PSR B0818-41, using the GMRT. We find simultaneous occurrence of three drift regions with two drift rates, an inner region with steeper apparent drift rate flanked on each side by a region of slower apparent drift rate. Furthermore, the two closely spaced drift regions always maintain a constant phase relationship. These unique drift properties seen for this pulsar is very rare. We interpret that the observed drift pattern is created by intersection of our line of sight (LOS) with two conal rings in a inner LOS (negative beta) geometry. We argue that the carousel rotation periodicity (P_4) and the number of sparks (N_sp) are the same for the rings and claim that P_4 is close to the measured P_3. Based on our analysis results and interpretations, we simulate the radiation from B0818-41. The simulations support our interpretations and reproduce the average profile and the observed drift pattern. The results of our study show that PSR B0818-41 is a powerful system to explore the pulsar radio emission mechanism, the implications of which are also discussed in our work.

    recruitment of professionals with incomplete education. In most LA countries only one MP responsible for each Center is currently mandated. Currently there is a large disparity among MP training programs and there is significant debate about the standards of MP graduate education in many LA countries. There are no commonly recognized academic programs, not enough clinical training sites and clinical training is not typically considered as part of the MP work. Economic pressures and high workloads also impede the creation of more training centers. The increasing need of qualified MPs require establishing a coordinated system of national Education & Training Centers (ETC), to meet the international standards of education and training in Medical Physics. This shortfall calls for support of organizations such as the IOMP, AAPM, ALFIM, IAEA, etc. Examples from various LA countries, as well as some proposed solutions, will be presented.

    Andreea-Teodora Stănescu


    Full Text Available Initially, the concept of unfair terms characterized only the contracts concluded between consumers and professionals. Currently, the concept is also incident in other types of contracts. This study only concerns the concept of unfair terms applicable to contracts concluded between consumers and professionals. Main regulations applicable are represented by Law no. 193/2000 on unfair terms in contracts concluded between professionals and consumers and Directive 93/13 / EEC on unfair terms in consumer contracts (interpreted by the ECJ. Scientific work is proposed to set up the concept of unfair terms. In order to do so, several steps are to be followed: 1. determining the scope (contracts on the sale of goods or services concluded between professionals and consumers 2. analysis of unfair terms defining features: (a the absence of negotiation between the contracting parties, (b the presence of a significant imbalance between the rights and obligations of the parties, to the detriment of consumers and (c the breach of good faith 3. the identification of the incident sanctions 4. the highlighting of some procedural features (especially in terms of the effects of court decisions finding the unfairness of a contractual term.

  12. Closing Remarks.



    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.

  14. Introductory remarks

    Panofsky, W.K.H.


    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

  16. Introductory remarks

    Pecker, J.-C.; Runcorn, S.K.


    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

  2. Opening remarks

    Foster, B. [Coal Association of Canada, Calgary, AB (Canada)


    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.

  3. Discussions about safety criteria and guidelines for radioactive waste management.

    Yamamoto, Masafumi


    In Japan, the clearance levels for uranium-bearing waste have been established by the Nuclear Safety Commission (NSC). The criteria for uranium-bearing waste disposal are also necessary; however, the NSC has not concluded the discussion on this subject. Meanwhile, the General Administrative Group of the Radiation Council has concluded the revision of its former recommendation 'Regulatory exemption dose for radioactive solid waste disposal', the dose criteria after the institutional control period for a repository. The Standardization Committee on Radiation Protection in the Japan Health Physics Society (The Committee) also has developed the relevant safety criteria and guidelines for existing exposure situations, which are potentially applicable to uranium-bearing waste disposal. A new working group established by The Committee was initially aimed at developing criteria and guidelines specifically for uranium-bearing waste disposal; however, the aim has been shifted to broader criteria applicable to any radioactive wastes.

  8. Review: Ralf Bohnsack, Aglaja Przyborski & Burkhard Schäffer (Eds. (2010. Das Gruppendiskussionsverfahren in der Forschungspraxis [The Group Discussion Technique in Research Practice

    Diana Schmidt-Pfister


    Full Text Available This edited volume comprises a range of studies that have employed a group discussion technique in combination with a specific strategy for reconstructive social research—the so-called documentary method. The latter is an empirical research strategy based on the meta-theoretical premises of the praxeological sociology of knowledge, as developed by Ralf BOHNSACK. It seeks to access practice in a more appropriate manner, namely by differentiating between various dimensions of knowledge and sociality. It holds that habitual collective orientations, in particular, are best accessed through group discussions. Thus this book does not address the group discussion technique in general, as might be expected from the title. Instead, it presents various contributions from researchers interpreting transcripts of group discussions according to the documentary method. The chapters are grouped into three main sections, representing different frameworks of practice and habitual orientation: childhood, adolescence, and organizational or societal context. A fourth section includes chapters on further, potentially useful ways of employing this particular technique and approach, as well as a chapter on teaching it in a meaningful way. Each chapter is structured in the same way: introduction to the research field and focus; methodological discussion; exemplary interpretation of group discussions; and concluding remarks. Whilst the transcripts referred to by the authors are very helpfully presented in the chapters, there is a lack of methodological reflection on the group discussion technique itself, which, as mentioned above, is only evaluated in regard to the documentary method.

  9. A remark on the motivic Galois group and the quantum coadjoint action

    Grosse, H.; Schlesinger, K.-G.


    It has been suggested that the Grothendieck-Teichmueller group GT should act on the Duflo isomorphism of su(2), but the corresponding realization of GT turned out to be trivial. We show that a solvable quotient of the motivic Galois group - which is supposed to agree with GT - is closely related to the quantum coadjoint action on U q (sl 2 ) for q a root of unity, i.e. in the quantum group case one has a nontrivial realization of a quotient of the motivic Galois group. From a discussion of the algebraic properties of this realization we conclude that in more general cases than U q (sl 2 ) it should be related to a quantum version of the motivic Galois group. Finally, we discuss the relation of our construction to quantum field and string theory and explain what we believe to be the 'physical reason' behind this relation between the motivic Galois group and the quantum coadjoint action. This might be a starting point for the generalization of our construction to more involved examples. (orig.)

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.

  14. The economy of climatic change. Discussion

    Boot, P.


    In a previous article in this magazine by Aalbers and Vollebergh it was concluded that good economic arguments are available for the precautionary principle in the climate control policy. That also pleads for a far-going Dutch climate control policy. It is the opinion of the author that the foundations of their arguments are not good enough. The above-mentioned authors reply with the one-page article 'De economie van Utopia' (The economy of Utopia) to Boot's article. 7 refs

  15. Review of intense irradiation data and discussion on structural integrity

    Suzuki, K.; Jitsukawa, S.; Okubo, N. [Japan Atomic Energy Agency, Tokai-mura, Naga-gun, Ibaraki-ken (Japan)


    Full text of publication follows: Mechanical property data on austenitic stainless steels and F82H have been reviewed to discuss for developing structural integrity methodologies of intensely irradiated components such as first walls. The following have been already clarified: (1) Fracture ductility is still high even though tensile rupture elongation is reduced remarkably. (2) Strain-hardening occurs in true stress-logarithmic strain (true strain) relationship. Work-softening behavior observed in nominal stress-nominal strain curves is simply resulted from a reduction of work hardening rate accompanied by the increase of flow stress level by irradiation. The review lead to an innovative design concept for application to intensely irradiated components. A special consideration is given to unique feature of bending moment in developing design methodology for preventing ductile fracture of intensely irradiated materials. Another discussion is also made on how to simulate mechanical behavior of intensely irradiated components, because mechanical testing of component-wise specimens after intense irradiation is inevitable for the development of design concepts, although irradiation on such a large scale specimen seems to be almost impossible with current irradiation facilities.

  16. Closing Remarks of the Workshop OnGlobal University System & E-Learning

    Ali YAIZCI


    Full Text Available The Workshop on Global University System & E-Learning was held on the 19th of October, 2006 at TOBB Economics & Technology University. The workshop attracted around 40 people from the Ministry of Education, Turkish Satellite Corporation (TURKSAT, Anadolu University, and various academic staff from different universities in Ankara. All together, there were 8 presentations each followed by a discussion. Main contributors, their brief CV’s, and the workshop program are included in the preceding part of this document.Here, I would try to put together various important points and remarks made by the speakers according to the order in the program.The first talk was presented by Professor Tapio Varis, Acting President of GUS, about the Global University System (GUS. He started his talk by reviewing the trends of the 21st Century in terms of education and technology. He emphasized the need to humanize the globalization process by adding “solidarity”, “sprit of caring for”, and “sharing with others”. It was stated that, content development, especially for educational purposes, is a difficult issue in achieving this process. Professor Varis, declared “digital literacy” as being a right for all. He mentioned “phonetic alphabet” as a tool to alleviate the problems associated with the communication among different nationalities. He mentioned the need to exchange ideas, opinions and experience to create a successful working environment and stressed the importance of cultural issues such as quality assurance, translation and assessment. He also talked about open courseware, “education for all”, offered by MIT and UNESCO. Finally, Professor Varis summarized the mission of GUS as to offer a global quality education (described as a renaissance education program for developing countries and/or regions by taking into account cultural sensitivities.The second talk was presented by Professor Takeshi Utsumi about the Global Collaborative

  17. Discussion on massive gravitons and propagating torsion in arbitrary dimensions

    Hernaski, C.A.; Vargas-Paredes, A.A.; Helayel-Neto, J.A.


    Full text. Massive gravity has been an issue of particular interest since the early days of Quantum Gravity. More recently, in connection with models based on brane-world scenarios, the discussion of massive gravitons is drawing a great deal of attention, in view of the possibility of their production at LHC and the feasibility of detection of quantum gravity effects at the TeV scale. In this paper, we reassess a particular R 2 -type gravity action in D dimensions, recently studied by Nakasone and Oda, taking now torsion effects into account. Considering that the vielbein and the spin connection carry independent propagating degrees of freedom, we conclude that ghosts and tachyons are absent only if torsion is non-propagating, and we also conclude that there is no room for massive gravitons. To include these excitations, we understand how to enlarge Nakasone-Oda's model by means of explicit torsion terms in the action and we discuss the unitarity of the enlarged model for arbitrary dimensions. To make this we construct a complete basis of operators that projects the degrees of freedom of the dynamical fields of the model in their irreducible spin decomposition. The outcome is that we find a set of Lagrangians with a massive graviton that, in D=4, reproduce those already studied in the literature. (author)

  18. Launching the chaotic realm of iso-fractals: A short remark

    O' Schmidt, Nathan [Department of Mathematics, Boise State University, 1910 University Drive, Boise, ID 83725 (United States); Katebi, Reza [Department of Physics, California State University in Fullerton, 800 North State College Boulevard, Fullerton, CA 92831 (United States); Corda, Christian [Institute for Theoretical Physics and Advanced Mathematics Einstein-Galilei (IFM), Via Santa Gonda 14, 59100 Prato (Italy)


    In this brief note, we introduce the new, emerging sub-discipline of iso-fractals by highlighting and discussing the preliminary results of recent works. First, we note the abundance of fractal, chaotic, non-linear, and self-similar structures in nature while emphasizing the importance of studying such systems because fractal geometry is the language of chaos. Second, we outline the iso-fractal generalization of the Mandelbrot set to exemplify the newly generated Mandelbrot iso-sets. Third, we present the cutting-edge notion of dynamic iso-spaces and explain how a mathematical space can be iso-topically lifted with iso-unit functions that (continuously or discretely) change; in the discrete case examples, we mention that iteratively generated sequences like Fibonacci’s numbers and (the complex moduli of) Mandelbrot’s numbers can supply a deterministic chain of iso-units to construct an ordered series of (magnified and/or de-magnified) iso-spaces that are locally iso-morphic. Fourth, we consider the initiation of iso-fractals with Inopin’s holographic ring (IHR) topology and fractional statistics for 2D and 3D iso-spaces. In total, the reviewed iso-fractal results are a significant improvement over traditional fractals because the application of Santilli’s iso-mathematics arms us an extra degree of freedom for attacking problems in chaos. Finally, we conclude by proposing some questions and ideas for future research work.

  20. Original article Determinants of personality in the scope of motivation for maintaining abstinence in the case of male alcohol-dependent individuals concluding therapy

    Jan Chodkiewicz


    Full Text Available Background The results of numerous studies indicate strong associations of personality with the occurrence, and also with the treatment, of alcohol dependence. However, there is no agreement regarding the role of particular dimensions of temperament and character in the course of, and for the results of, alcohol rehabilitation therapy. The objective of the present research was to investigate the relationships between the dimensions of temperament and character as they are presented by Robert Cloninger and motivation for maintaining abstinence in the case of male alcohol-dependent individuals concluding the therapy. Participants and procedure Eighty-nine male alcohol-dependent individuals, concluding alcohol rehabilitation therapy in an outpatient setting, were studied. The following research tools were applied: the Temperament and Character Inventory (TCI of R. Clo­ninger in the Polish adaptation of E. Hornowska (2003, and the Motivation for Maintaining Abstinence Inventory, the author of which is M. Ziółkowski. Results Two clusters, differing in the aspect of motivation for maintaining abstinence after the conclusion of the treatment, were distinguished: of individuals manifesting weaker motivation (n = 39 and those manifesting stronger motivation (n = 50. The patients with stronger motivation manifested the following major features: a lower level of harm avoidance, a higher level of reward dependence, and a higher level of cooperativeness. Conclusions Personality as it is presented by Cloninger manifests connections with motivation for maintaining abstinence. The research confirms the need for diagnosing addicted patients in the scope of temperament and character traits.

  1. Critical comparison of intravenous injection of TiO2 nanoparticles with waterborne and dietary exposures concludes minimal environmentally-relevant toxicity in juvenile rainbow trout Oncorhynchus mykiss

    Boyle, David; Al-Bairuty, Genan A.; Henry, Theodore B.; Handy, Richard D.


    A critical comparison of studies that have investigated tissue accumulation and toxicity of TiO 2 -NPs in fish is necessary to resolve inconsistencies. The present study used identical TiO 2 -NPs, toxicological endpoints, and fish (juvenile rainbow trout Oncorhynchus mykiss) as previous studies that investigated waterborne and dietary toxicity of TiO 2 -NPs, and conducted a critical comparison of results after intravenous caudal-vein injection of 50 μg of TiO 2 -NPs and bulk TiO 2 . Injected TiO 2 -NPs accumulated only in kidney (94% of measured Ti) and to a lesser extent in spleen; and injected bulk TiO 2 was found only in kidney. No toxicity of TiO 2 was observed in kidney, spleen, or other tissues. Critical comparison of these data with previous studies indicates that dietary and waterborne exposures to TiO 2 -NPs do not lead to Ti accumulation in internal tissues, and previous reports of minor toxicity are inconsistent or attributable to respiratory distress resulting from gill occlusion during waterborne exposure. -- Highlights: •Critical comparison of TiO 2 -NP toxicity studies in rainbow trout. •No evidence of TiO 2 -NP absorption in internal tissues. •Conclude minimal environmentally relevant toxicity of TiO 2 -NPs in rainbow trout. -- Critical evaluation of directly comparable investigations of TiO 2 -NP toxicity by waterborne, dietary, and intravenous injection exposures conclude minimal toxicity in juvenile rainbow trout

  4. Online discussion: Enhancing students' critical thinking skills

    Rathakrishnan, Mohan; Ahmad, Rahayu; Suan, Choo Ling


    Online discussion has become one of the important strategies for the teacher to teach the students to think critically when conveying their ideas and become more proactive and creative. In this paper, padlet online discussion communication was conducted to examine its effectiveness in enhancing critical thinking. In this study, there are two types of critical thinking: macro and micro critical thinking. A total of 70 Universiti Utara Malaysia Management Foundation Programme students involved in this experimental research design. The students in treatment class are divided to few groups. Every group uses padlet online discussion to discuss the topic given. All the group members discuss and write their ideas in padlet. Ideas that are posted in padlet will be displayed in front of the class so that the entire group in the treatment class could see the given ideas. Paul's (1993) model was used to analyze student's macro and micro critical thinking in padlet online discussion and communication. The finding shows that students who used padlet online discussion backchannel communication have greater macro and micro critical thinking level than students who do not use online discussion.

  1. Chinese women's participation in fertility discussions.

    Li, L


    In an attempt to better understand the process through which the family planning (FP) programs and socioeconomic developments in China affect fertility, women's participation in fertility discussions with their husbands are examined as an intermediate factor in a study based on results of a random survey of 6654 ever-married women of reproductive age from 7 cities and 30 counties of Guangdong. First, it must be noted that Chinese couples do have individual choices (albeit quite limited ones) about their fertility; they can choose to follow or ignore government policy or they can choose to remain childless. The present study has 3 major hypotheses: 1) the more a woman is involved in fertility discussions with her husband, the fewer children she will have; 2) urban women with a higher educational status will be more likely to have such discussions; and 3) women who are contacted individually by FP personnel are more likely to be involved in fertility discussions. After a discussion of data collection and variables (number of living children, education of wife and husband, age at marriage, residence, living with parents, contacted by FP personnel, and discussion with husband), the results are presented in terms of zero-order correlation coefficients indicating their relationships. The bivariate analysis supported the hypotheses. Multiple regression analysis showed that age at marriage, education of wives and husbands, FP contacts, and participation in discussions remain significant fertility determinants (but the correlation between fertility and residence becomes trivial). A further regression model indicated that a woman's educational attainment is the most significant positive indication of their participation in fertility discussions. These results imply that as women's status continues to improve in China and the deeply-rooted patriarchal tradition loses hold, increased gender equity and education will influence a fertility decline. FP personnel could also

  2. Concluding report by the committee of experts on the Brunsbuettel and Kruemmel nuclear power stations. Vattenfall to implement the set of measures and all recommendations

    Hassa, R.


    The independent Committee of Experts appointed by Vattenfall Europe after the events of June 28, 2007 in the Brunsbuettel and Kruemmel nuclear power stations concluded its investigations. The Committee had been asked to investigate and evaluate the situation associated with the events, and to elaborate proposals for improvement on this basis. The analysis by the Committee of Experts boils down to the finding that the Brunsbuettel and Kruemmel nuclear power stations represent a modern standard as far as design concepts and technical safety features are concerned. Besides technical preconditions, also the administrative features are in place for safe plant oepration. No indications were found of any deficits in safety culture which would justify doubt about the reliability of the operator or the staff responsible under the Atomic Energy Act, nor is there any doubt about the level of technical expertise. Vattenfall directly ordered the findings to be implemented by applying, for part of the technical measures, for implementation with the Kiel State Ministry for Social Affairs as the competent regulatory agency. The Vattenfall Group is going to establish a new safety organization and safety controlling for the nuclear power plants operated by the company. These measures are to ensure an optimum safety level and the highest safety standards. With Vattenfall, safety enjoys top priority. (orig.)

  3. On the legal nature of electricity supply contracts concluded by electricity companies and power stations generating electricity from renewable energy sources

    Herrmann, B.J.


    Section 2 of the German Act for enhanced use of electricity from renewable energy sources (StEG) defines the obligation to contract but not the contractual obligations, i.e. the conditions of performance of the contract (supply and purchase of electricity and the legal obligations of contractors). The analysis here shows that characterising this mandatory contract required by the act as an agreement of purchase and sale more appropriately describes the legal nature of the contract and the intent of the legislator than other contracts for supply and purchase of electricity, as for instance those concluded by electric utilities and their customers. One specific aspect elaborated by the author is that the StEG does not constitute an obligation to supply on the part of the renewable energy generating power station, so that the power station operator is not obliged to ensure availability of the electricity at any time or in terms of supplies that can be called off by the purchasing utility, whereas the electric utility is obliged by section 2 of the StEG to purchase the contractual amounts from the generating station.

    Interactive communication on the Internet, as illustrated by the e-mail-based breast cancer discussion group, provides an alternative to the telephone, the fax machine and regular mail, and is a resource for communications research, the potential of which is only beginning to be appreciated. At least some of the messages posted to such discussion groups could be regarded as a form of "journaling". Such messages are eminently suitable for qualitative data analysis.

  10. Notas sobre o Behaviorismo de ontem e de hoje Remarks on former and current Behaviorism

    Emmanuel Zagury Tourinho


    Full Text Available Este artigo busca oferecer algumas referências históricas sobre as origens e desenvolvimentos da Psicologia behaviorista. O artigo parte das contribuições de Watson, destacando seu afastamento do modo causal selecionista, inaugurado na Psicologia por Thorndike. Em seguida, discute alguns desenvolvimentos do behaviorismo sob a liderança de Skinner, apontando que seus avanços resultam em grande medida do retorno ao selecionismo. O artigo argumenta, por fim, que ao final do século XX a abordagem inaugurada por Skinner estende-se a em muitas direções, configurando a análise do comportamento como um sistema multidimensional. O artigo conclui com a indicação de que uma visão histórica do processo de investigação comportamental oferece um quadro mais preciso do que essa abordagem tem representado enquanto sistema na Psicologia.This paper aims at offering some historical references concerning the origins and development of behaviorist Psychology. It begins with Watson's contributions and highlights his detachment from the causal mode of selection by consequence started in Psychology by Thorndike. Then, the paper discusses some developments of behaviorism under the leadership of Skinner and argues that some achievements have largely resulted from a recovery of selectionism. Finally, it contends that, by the end of the 20th century, the approach started by Skinner extended to new directions, engendering behavior analysis as a multidimensional system. The paper concludes by pointing out that a historical view of the process of behavioral investigation provides a more precise frame of what this approach has represented as a psychological system.

    This is the concluding Progress Report for Project 1.1 of the U.S./Russia Joint Coordinating Committee on Radiation Effects Research (JCCRER). An overwhelming majority of our work this period has been to complete our primary obligation of providing a new version of the Techa River Dosimetry System (TRDS), which we call TRDS-2009D; the D denotes deterministic. This system provides estimates of individual doses to members of the Extended Techa River Cohort (ETRC) and post-natal doses to members of the Techa River Offspring Cohort (TROC). The latter doses were calculated with use of the TRDS-2009D. The doses for the members of the ETRC have been made available to the American and Russian epidemiologists in September for their studies in deriving radiogenic risk factors. Doses for members of the TROC are being provided to European and Russian epidemiologists, as partial input for studies of risk in this population. Two of our original goals for the completion of this nine-year phase of Project 1.1 were not completed. These are completion of TRDS-2009MC, which was to be a Monte Carlo version of TRDS-2009 that could be used for more explicit analysis of the impact of uncertainty in doses on uncertainty in radiogenic risk factors. The second incomplete goal was to be the provision of household specific external doses (rather than village average). This task was far along, but had to be delayed due to the lead investigator’s work on consideration of a revised source term.

  12. [Computer mediated discussion and attitude polarization].

    Shiraishi, Takashi; Endo, Kimihisa; Yoshida, Fujio


    This study examined the hypothesis that computer mediated discussions lead to more extreme decisions than face-to-face (FTF) meeting. Kiesler, Siegel, & McGuire (1984) claimed that computer mediated communication (CMC) tended to be relatively uninhibited, as seen in 'flaming', and that group decisions under CMC using Choice Dilemma Questionnaire tended to be more extreme and riskier than FTF meetings. However, for the same reason, CMC discussions on controversial social issues for which participants initially hold strongly opposing views, might be less likely to reach a consensus, and no polarization should occur. Fifteen 4-member groups discussed a controversial social issue under one of three conditions: FTF, CMC, and partition. After discussion, participants rated their position as a group on a 9-point bipolar scale ranging from strong disagreement to strong agreement. A stronger polarization effect was observed for FTF groups than those where members were separated with partitions. However, no extreme shift from their original, individual positions was found for CMC participants. There results were discussed in terms of 'expertise and status equalization' and 'absence of social context cues' under CMC.

  13. Proceeding of human exoskeleton technology and discussions on future research

    Li, Zhiqiang; Xie, Hanxing; Li, Weilin; Yao, Zheng


    After more than half a century of intense efforts, the development of exoskeleton has seen major advances, and several remarkable achievements have been made. Reviews of developing history of exoskeleton are presented, both in active and passive categories. Major models are introduced, and typical technologies are commented on. Difficulties in control algorithm, driver system, power source, and man-machine interface are discussed. Current researching routes and major developing methods are mapped and critically analyzed, and in the process, some key problems are revealed. First, the exoskeleton is totally different from biped robot, and relative studies based on the robot technologies are considerably incorrect. Second, biomechanical studies are only used to track the motion of the human body, the interaction between human and machines are seldom studied. Third, the traditional developing ways which focused on servo-controlling have inborn deficiency from making portable systems. Research attention should be shifted to the human side of the coupling system, and the human ability to learn and adapt should play a more significant role in the control algorithms. Having summarized the major difficulties, possible future works are discussed. It is argued that, since a distinct boundary cannot be drawn in such strong-coupling human-exoskeleton system, the more complex the control system gets, the more difficult it is for the user to learn to use. It is suggested that the exoskeleton should be treated as a simple wearable tool, and downgrading its automatic level may be a change toward a brighter research outlook. This effort at simplification is definitely not easy, as it necessitates theoretical supports from fields such as biomechanics, ergonomics, and bionics.

  7. Discussing the theological grounds of moral principles.

    Heller, Jan C


    Discussing the theological beliefs that ground Catholic moral principles can make some people uncomfortable, even while others will appreciate it. But these reactions will sometimes be revealed not as the emotions they are, but as objections to the relative independence or dependence of morality on foundational beliefs. In the end, context should dictate whether one displays the theological beliefs that ground Catholic moral principles.

  14. Conflicting perspectives compromising discussions on cardiopulmonary resuscitation.

    Groarke, J


    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    Under the auspices of Bacchus! Acutissimins, natural flavano-ellagitannins, occur in oak-aged wine as a result of a diastereoselective condensation reaction of the flavan-3-ol catechin, a component of grapes, with the C-glucosidic ellagitannin vescalagin, found in oak. The acutissimins are further converted into natural mongolicains and analogues of camelliatannin G in a remarkably chemoselective fashion by simple aerobic oxidation.

In these letters the pursuit for the Holy Spirit as the foundation of knowledge is remarkably noticeable, so that it could be argued that this experience contributes and gives rise to the rejection both of rationalism and of materialism of the philosophy.

  12. In quest of a relativistic constituent quark model - some constructive remarks

    Hofsaess, T.; Schierholz, G.


    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

  14. Can warming particles enter global climate discussions?

    Bond, Tami C


    'Soot' or 'black carbon', which comes from incomplete combustion, absorbs light and warms the atmosphere. Although there have been repeated suggestions that reduction of black carbon could be a viable part of decreasing global warming, it has not yet been considered when choosing actions to reduce climatic impact. In this paper, I examine four conceptual barriers to the consideration of aerosols in global agreements. I conclude that some of the major objections to considering aerosols under hemispheric or global agreements are illusory because: (1) a few major sources will be addressed by local regulations, but the remainder may not be addressed by traditional air quality management; (2) climate forcing by carbon particles is not limited to 'hot spots'-about 90% of it occurs at relatively low concentrations; (3) while aerosol science is complex, the most salient characteristics of aerosol behavior can be condensed into tractable metrics including, but not limited to, the global warming potential; (4) despite scientific uncertainties, reducing all aerosols from major sources of black carbon will reduce direct climate warming with a very high probability. This change in climate forcing accounts for at least 25% of the accompanying CO 2 forcing with significant probability (25% for modern diesel engines, 90% for superemitting diesels, and 55% for cooking with biofuels). Thus, this fraction of radiative forcing should not be ignored

  15. Axial nonimaging characteristics of imaging lenses: discussion.

    Siew, Ronian


    At observation planes away from the image plane, an imaging lens is a nonimaging optic. We examine the variation of axial irradiance with distance in image space and highlight the following little-known observation for discussion: On a per-unit-area basis, the position of the highest concentration in image space is generally not at the focal plane. This characteristic is contrary to common experience, and it offers an additional degree of freedom for the design of detection systems. Additionally, it would also apply to lenses with negative refractive index. The position of peak concentration and its irradiance is dependent upon the location and irradiance of the image. As such, this discussion also includes a close examination of expressions for image irradiance and explains how they are related to irradiance calculations beyond the image plane. This study is restricted to rotationally symmetric refractive imaging systems with incoherent extended Lambertian sources.

  3. A licensing discussion: SMRs in Canada

    De Vos, M.


    The CNSC (Canadian AECB) is ready to regulate Small Modular Reactors (SMR) facilities in Canada. The CNSC is well situated to engage with proponents of SMR reactors in design reviews or licensing discussions. A risk-informed (graded) approach is possible in many instances for reactors but it is not a relaxation of requirements. The vendor design review process helps reduce regulatory risks by encouraging early engagement.

  4. Round table discussion during session 1

    Aebersold, M.


    The round table discussions of the first session of the Belgium Workshop addressed the following questions: - Accepting or refusing a person, an institution or a grouping as a legitimate Stakeholder who makes the decision and how? - How are the local partnerships built and organised? - How to obtain community support for the partnership's legitimate decisions/findings? - Experience teaches that no decision is reached solely by formal and legal processes. What role do informal processes play? - How can the informal procedures be accepted? Do they need to be made explicit? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. After the discussion, each table's findings were reported to the plenary. Most of the discussion concerned the local partnerships. Important findings were that the statutes for the partnerships were developed by the partnerships themselves and there were no legally binding rules handed down by the federal level. The partnerships are part of an informal process. A legally binding participation (i.e. within the EIA) will be initiated at a later stage. As the partnerships function outside of the formal legal procedure, they can function in a more flexible way. It was noted that the partnerships make recommendations, but it is not clear what the government will do with these recommendations. It was also argued that the process may cause conflicts between neighboring communities. As in other contexts visited by the FSC, the importance of the right of veto of the community was stressed, although this may cause a conflict between technical suitability and social acceptance. Access of the community to the local partnership is necessary. Finally it was accepted that time is needed to explain the recommendations to the broader community before any decisions are taken.

  12. Round table discussion during session 2

    Mays, C.


    The round table discussions of the second session of the FSC Belgium Workshop addressed the following questions: - Do local stakeholders have, internally or externally, all the expertise they need in order to address the issues raised by radioactive waste management projects? - Do institutional stakeholders have all the expertise they need to take local impacts into account? - What kinds of expert input are sought and attained by the different stakeholders? - Were any formal methods used to aid local partnerships perform technology assessments? Or other types of assessment? - How to maintain the knowledge and expertise achieved by the stakeholders? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. As in Session I, most of the round table discussion focussed specifically on the experience of the local partnerships. Many insights were shared about the nature and role of expertise in complex decision making. They are summarised below, on the basis of the feedback provided to the plenary by each round table. Some of these insights can be generalised to other contexts. All in all, a profile emerged of the local partnerships as a unique and effective tool to deal with knowledge issues in managing risk.

  14. The debate about death: an imperishable discussion?



    Full Text Available In this concise review we discuss some of the complex edges of the concept of death that arose after the notorious advances in science and medicine over the last 50 years, in which the classical cardio-pulmonary criteria have led to the neurological criteria of death. New complicated questions like the definition of death and the operational criteria for diagnosing it have arisen and we think that they are far from being adequately and satisfactorily solved. A number of important issues -like the reliability and differences between cardio-pulmonary versus brain based criteria of death, if death is an event or a process, the meaning of integration and irreversibility- have not yet received sufficient attention. Here we have approached the death problem from two (biological complex system perspectives: the organism level and the cellular-molecular level. We also discuss issues from a third systemic approach, that is, the entire society, thus involving legal, religious, bioethical and political aspects of death. Our aim is to integrate new perspectives in order to promote further discussion on these critical yet frequently neglected issues

  15. Nuclear waste under glass, further discussion

    O'Keefe, J. A.; Barkatt, A.; Glass, B. P.; Alterescu, S.

    J. J. Crovisier and J. Honnorez [1988] discuss an article by W. W. Maggs, “Mg May Protect Waste Under Glass” [Maggs, 1988] summarizing work by A. Barkatt (Catholic University, Washington, D.C.), B. P. Glass (University of Delaware, Newark), and S. Alterescu and J. A. O'Keefe (NASA/GSFC, Greenbelt, Md.). We found that seawater is orders of magnitude less corrosive t h an fresh water in attacking tektite glass; traced the protective effect to the presence of magnesium, at a level of about 1.3 g/L in seawater; and suggested that the effect might be useful in protecting nuclear waste glasses from corrosion.Crovisier and Honnorez first make the point that the rate of corrosion of glass is, in principle, a function of the ratio of surface area 5 to the effective volume V. This concept, which is usually discussed in American literature under the name of S/V effects, is discussed by Crovisier and Honnorez in terms of the “permeability of the environment.” These effects have been carefully considered throughout our work (see, for example, Barkatt et al. [19867rsqb;). It turns out that in the sea the effective S/V is so small that the effects referred to by Crovisier and Honnorez can be ignored.

  16. Focus group discussion in mathematical physics learning

    Ellianawati; Rudiana, D.; Sabandar, J.; Subali, B.


    The Focus Group Discussion (FGD) activity in Mathematical Physics learning has helped students perform the stages of problem solving reflectively. The FGD implementation was conducted to explore the problems and find the right strategy to improve the students' ability to solve the problem accurately which is one of reflective thinking component that has been difficult to improve. The research method used is descriptive qualitative by using single subject response in Physics student. During the FGD process, one student was observed of her reflective thinking development in solving the physics problem. The strategy chosen in the discussion activity was the Cognitive Apprenticeship-Instruction (CA-I) syntax. Based on the results of this study, it is obtained the information that after going through a series of stages of discussion, the students' reflective thinking skills is increased significantly. The scaffolding stage in the CA-I model plays an important role in the process of solving physics problems accurately. Students are able to recognize and formulate problems by describing problem sketches, identifying the variables involved, applying mathematical equations that accord to physics concepts, executing accurately, and applying evaluation by explaining the solution to various contexts.

  17. Discussion of some issues in risk study

    Qu Jingyuan; Liu Yuanzhong


    The concept of risk, the methods for assessing risk and the acceptability of risk are discussed. The emphasis was laid on the three components for complete description of a risk: scenario, probability and consequence of an event. The disadvantages of the concept and presentation of risk used in some risk analysis were pointed out. The paper emphasized that it is necessary to explicitly consider the multi-dimensionality of risk in the assessment and management of risk. Several important factors influencing the acceptability of risk and the methodology for evaluating the acceptability of risk were also described

  18. Experts' discussion on reactor safety research


    The experts' discussion on reactor safety research deals with risk analysis, political realization, man and technics, as well as with the international state of affairs. Inspite of a controversy on individual issues and on the proportion of governmental and industrial involvment in reactor safety research, the continuation and intensification of corresponding research work is said to be necessary. Several participants demanded to consider possible 'conventional accidents' as well as a stronger financial commitment by the industry in this sector. The ratio 'man and technics' being an interface decisive for the proper functioning or failure of complex technical systems requires even more research work to be done. (GL) [de

The discussion will include comments from speakers from different parts of the nuclear industry and other industries regarding benefits and weaknesses of performance-based regulation. (authors)

  4. Discussing the Prospects of European Democracy with Alexis de Tocqueville

    Dalia Eidukienė


    Full Text Available This article analyses the concept of democracy proposed by Alexis de Tocqueville, a famous French historian and sociologist. Special attention is paid to the definition of democracy, the dialectics of freedom and equality as well as the issues of relationship between democracy and centralization of power, democracy and individualism, and democracy and the tyranny of the majority. Tocqueville‘s liberal theory is an excellent example of the political project of the early modern period; it was in step with or, in many cases, ahead of France‘s political evolution, thereby contributing to the formation of the intellectual climate of the later 20th century. More than that, Tocqueville‘s political thought remains relevant even today. He is valued as an innovator, who, as Zbigniew Brzezinski put it, „understood earlier and interpreted better than anyone the uniqueness of the American experiment... His judgements are to this day remarkably prescient and incisive“ (Brzezinski 2011. Consequently, Tocqueville‘s book Democracy in America is a text that is worth being reread. In each political period the readers of this text rediscover anew the meaning of the messages communicated by the author. This depends on the political consciousness, political culture and the „quality“ of the recipients, i.e. on their ability to process and adapt the received information to their times, their state, their specific situation or a specific subject. Tocqueville invites his readers to engage in communicative reading (i.e. dialogue and discussions, which is an important part of modern political communication and political practice. It is also one of the most important attributes of politics and a reliable instrument that makes it easier to form modern political theories and solve political problems. 

  5. Local Information Commission of Dampierre-en-Burly, meeting of November 25, 2011. Additional safety assessment. Collection of remarks by the members of the Commission on the report presented by the CNPE to the ASN on 15/9/2011

    De Ganay, C.


    This report first discusses the specifications of the additional nuclear safety assessment. The authors state that this procedure is limited to the robustness of installations and to some climatic events. They formulate several and questions on issues which are not sufficiently or even not at all addressed in these specifications. In a second part, they make remarks on the report made about the Dampierre nuclear power plant. These remarks address the different issues of the assessment: earthquakes, flooding, other extreme natural phenomena, loss of electricity supplies and cooling systems, severe accidents

  6. Accelerating Cleanup: Focus on 2006. Discussion draft


    This executive summary addresses the activities associated with the National Transuranic (TRU) Program managed by the Carlsbad Area Office (CAO). The CAO programmatically reports to the Assistant Secretary for Environmental Management and receives administrative support through the Albuquerque Operations Office. The mission of the Carlsbad Area Office (CAO) is to protect human health and the environment by opening and operating the Waste Isolation Pilot Plant for site disposal of TRU waste and by establishing an effective system for management of TRU waste from generation to disposal. It includes personnel assigned to the CAO, the Waste Isolation Pilot Plant (WIPP) site operations, and other activities associated with the National TRU Program. The CAO develops and directs implementation of the program, while the DOE Headquarters establishes policy and guidelines. The CAO assesses compliance with the program guidance, as well as the commonality of activities and assumptions among all the sites. Since the development of the February 28, 1997, database used to develop this Discussion Draft, the opening of the WIPP facility for receipt of Contact Handled waste has been delayed from November 1997 to May 1998. This slippage is significant enough to require a change in the milestones and volumes included in the documents to be reviewed by our stakeholders. Changes have been incorporated into this Discussion Draft and its supporting Project Baseline Summaries (PBSs)

  7. Brain plasticity, memory, and aging: a discussion

    Bennett, E.L.; Rosenzweig, M.R.


    It is generally assumed that memory faculties decline with age. A discussion of the relationship of memory and aging and the possibility of retarding the potential decline is hampered by the fact that no satisfactory explanation of memory is available in either molecular or anatomical terms. However, this lack of description of memory does not mean that there is a lack of suggested mechanisms for long-term memory storage. Present theories of memory usually include first, neurophysiological or electrical events, followed by a series of chemical events which ultimately lead to long-lasting anatomical changes in the brain. Evidence is increasing for the biochemical and anatomical plasticity of the nervous system and its importance in the normal functioning of the brain. Modification of this plasticity may be an important factor in senescence. This discussion reports experiments which indicate that protein synthesis and anatomical changes may be involved in long-term memory storage. Environmental influences can produce quantitative differences in brain anatomy and in behavior. In experimental animals, enriched environments lead to more complex anatomical patterns than do colony or impoverished environments. This raises fundamental questions about the adequacy of the isolated animal which is frequently being used as a model for aging research. A more important applied question is the role of social and intellectual stimulation in influencing aging of the human brain.

  8. Best Friends’ Discussions of Social Dilemmas

    McDonald, Kristina L.; Malti, Tina; Killen, Melanie; Rubin, Kenneth H.


    Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4% female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend's reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents’ social and moral development. PMID:23666555

  10. Panel discussion: Chemistry aspects of pet radiotracers

    Kilbourn, M.R.


    A panel discussion on the radiotracer development process opened with a question regarding the role of toxicological studies in the process of obtaining a physician-sponsored Investigational New Drug (IND) for a new radiopharmaceutical. Panel members were uniformly supportive of new radiotracer development, expressing their opinions that the regulatory hurdles were there but could be overcome. Several institutions are actively working with regulatory agencies to determine just what toxicology data are relevant to new radiopharmaceutical development in the PET field. The FDA is beginning to understand that the pharmacology of PET tracer doses may be completely different from what is usually important in drug trials. The second part of the panel discussion centered on the role, if any, of the pharmaceutical companies in new radiotracer development. It was pointed out that what the radiochemist is looking for in a radiopharmaceutical is different from what these companies are searching for in a therapeutic drug. Panel and audience members responded to the question: What would a pharmaceutical company gain from collaboration with radiopharmaceutical research laboratories? Several examples were given such as providing crucial data from humans rather than animals; determining individualized drug doses to maximize the therapeutic index of a new drug regimen; and replacing the large amounts of time and money currently invested by drug companies in the radiolabeling and evaluation of metabolites of new drugs

The library has tried to fulfill this request while attempting to preserve these treasures for future generations. As small university, without a trained archivist or preservationist, we have utilized resources outside our library and contiue to pursue sources to assist us in the maintenance of these special collections while still engaging them in the educational process.

  12. A remarkable new genus of Protosmylinae (Neuroptera: Osmylidae) from late Eocene Florissant, Colorado.

    Makarkin, Vladimir N


    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.

  13. Spent nuclear fuel reprocessing and international law. Germany's obligations under international law in matters of spent fuel reprocessing and the relevant contracts concluded with France and the United Kingdom

    Heintschel v Heinegg, W.


    The review presented is an excerpt from an expert opinion written by the author in December last year, in response to changes in nuclear energy policy announced by the new German government. The reprocessing of spent nuclear fuels from German power reactors in the reprocessing facilities of France (La Hague) and the UK (Sellafield) is not only based on contracts concluded by the German electric utilities and the French COGEMA or the British BNFL, but has been agreed as well by an exchange of diplomatic notes between the French Ministry of Foreign Affairs and the German ambassador in Paris, the German Foreign Ministry and the French ambassador as well as the British ambassador in Bonn. The article therefore first examines from the angle of international law the legal obligations binding the states involved, and Germany in particular, in matters of spent fuel reprocessing contracts. The next question arising in this context and discussed by the article is that of whether and how much indemnification can be demanded by the reprocessing companies, or their governments, resp., if Germany should discontinue spent fuel reprocessing and thus might be made liable for breach of the bilateral agreements.

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 5, 2007) following the short presentations—each reported as a separate article in the present volume—by Joseph Smith Jr., Howard Butler, Andrew Foley, Kimberly Hamad-Schifferli, Bernhardt Trout, Jeffery Lewins, Enzo Zanchini, and Michael von Spakovsky. All panelists and the audience were asked to address the following questions • Why is the second law taught in so many different ways? Why so many textbooks on thermodynamics? Why so many schools of thought? • Some say that thermodynamics is limited to equilibrium, others that it extends to nonequilibrium. How is entropy defined for nonequilibrium states?

  15. An uplifting discussion of T-duality

    Harvey, Jeffrey A.; Moore, Gregory W.


    It is well known that string theory has a T-duality symmetry relating circle compactifications of large and small radius. This symmetry plays a foundational role in string theory. We note here that while T-duality is order two acting on the moduli space of compactifications, it is order four in its action on the conformal field theory state space. More generally, involutions in the Weyl group W ( G) which act at points of enhanced G symmetry have canonical lifts to order four elements of G, a phenomenon first investigated by J. Tits in the mathematical literature on Lie groups and generalized here to conformal field theory. This simple fact has a number of interesting consequences. One consequence is a reevaluation of a mod two condition appearing in asymmetric orbifold constructions. We also briefly discuss the implications for the idea that T-duality and its generalizations should be thought of as discrete gauge symmetries in spacetime.

  16. Is rational discussion of open access possible?

    Rick Anderson


    Full Text Available Open Access (OA, like any other model or strategy for the dissemination of knowledge, carries with it clear benefits as well as costs and downsides. These vary depending on the OA strategy in question, and in order for OA to bring maximum benefit to the world of scholarship, its costs and benefits need be examined carefully and dispassionately so that the former can be maximized and the latter minimized. Unfortunately, the OA advocacy community tends to resist all attempts to examine OA in this way, to the point that those who approach OA in a spirit of critical analysis (rather than celebration and evangelism are attacked and punished. This article describes the problem, provides examples of it, and proposes strategies for promoting a more rigorous and analytical discussion of OA.

  17. WTC. A discussion on built space regeneration

    Marina Mihăilă


    Full Text Available Before 9/11 WTC was an international landmark. The definition of the two high-rise buildings identity, their tourist, social, visual and economic significance, disappeared with the destruction of their materiality. As a result, the contemplative visual and unwritten discourse of the Lower Manhattan disappeared together with the architectural, urban, technological essence and also with the philosophy of stability and equilibrium of a prosperous society. At the social-mental level this event triggers a crisis in personal and collective consciences (of the American Nation but also of the Nations, and a crisis of humanity. The architectural - urban and ideas competition organized to select the best urban-social-architectural concept proved to be a difficult task. Not only it had to “fill” a particular place on earth, but it also needed to configure a philosophy of place that would ‘heal” the wounds of the local and international communities, namely the lack of security and prosperity brought on by a no longer hidden technology of aggression bringing cities and communities under threats never experienced before at times of peace. In its first part the article discusses the competition, proposals and the finalized urban project. The particular challenges related to the selection of design in the case of WTC are doubled by a certain complexity related to the institutional arrangements common to most large urban development projects. It is also clear that there is interdependency between the project governance and the project results. These aspects are discussed in the second part of the article.

  18. Round-table discussion on food irradiation


    The possibilities of using radiation for food preservation as a way of alleviating the food deficiency problem in a large part of the world has been studied for some 20 years. Since the idea was recognized as a viable one, scientists had to develop it along three levels: firstly, the technological problems and economic viability had to be faced; at the same time tests had to be initiated to prove the wholesomeness of the irradiated foodstuffs, and then public acceptance and confidence in the end product had to be established. Work is proceeding along these three lines and in some cases, success has been won on all fronts. In others, it is continuing. As a FLASHBACK to the situation TWO YEARS AGO, we thought it interesting to reprint excerpts from a round-table discussion at which scientists from five countries sat down to discuss the pros and cons of food irradiation. ost at the gathering was Dr. Rocco Basson, Director of Chemistry at Pelindaba, South Africa, and the man responsible for directing radiation processing in that country. With him were Dr. Lapidot, Head of the Radiation and Engineering and Processing Section of the Israel Atomic Energy Commission at Soreq; Dr. Saint-Lebe of the Radioagronomy Service, French Atomic Energy Commission, at Cadarache; Dr. Ulmann, then Director of the Food Irradiation Pilot Plant at Wageningen in Holland; and Mr. Roy Hickman, leader of the International Project in the Field of Irradiation, sponsored by the FAO, IAEA and the OECD Nuclear Energy Agency, centred at Karlsruhe in Germany.

  19. Eugenol—From the Remote Maluku Islands to the International Market Place: A Review of a Remarkable and Versatile Molecule

    Alvaro M. Viljoen


    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.

  20. A remarkable finding that suggests the existence of a new groundwater biome based on chemoautotrophic resources, named

    Ştefan Negrea


    Full Text Available An important work of subterranean biology, signed by Francis Dov Por, Ophel: a groundwater biome based on chemoautotrophic resources. The global significance of the Ayyalon cave finds, Israel is presented and discussed in the present paper. The subject is a remarkable discovery suggesting the existence of a new aquatic subterranean biome autonomous energy based the author calls Ophel, the Hebrew word for “darkness” and “netherworld”. For F.D. Por, this biome links different marine chemosynthetic ecosystems in a global biospheric entity. Finally, F.D. POR hypothesizes on the existence of three overlapped biospheres: the bacteriosphere in the depths of the planet’s crust, which does not require light or oxygen; the aphotic, subterranean deuterobiosphere, formed of bacterial chemosynthesis based eukaryotes and limited-supplied dissolved oxygen from above-ground; the above-ground eubiosphere, based on aerobic photosynthesis. I would like to emphasize that, at my suggestion, Prof. Dr. F.D. Por participated at the 18th International Symposium of Biospeleology from Cluj-Napoca (Romania at 10th to 15th July 2006 where he mentioned for the first time orally some data on the Ayyalon Cave and the Ophel biome.
