    Full Text Available The 20th century’s epistemological turn in social sciences (Denzin & Lincoln, 1994; Punch, 2013 acknowledged the importance of qualitative research methods. The need for this turn was also pointed out by Habermas (1979, who noticed that the way data was collected in social sciences affected the analysis and data interpretation. Research gained a comprehensive character and proposed a phenomenological approach of reality (Guba & Lincoln, 1994; Willig, 2008; Lindlof & Taylor, 2011. Nowadays, we notice a “more confident community of scholars” whose earlier endeavors had “opened up the study of cultures, meanings, symbolic performances, and social practices” (Lindlof & Taylor, 2002, p. xi.

    A review is given of certain applications of NAA in geology. The emphasis is placed on reactor activation and the efficiency of NAA in gelogical research. The statements made are illustrated by a few examples showing the determination of rare elements in granites and fluorites, measurement of osmium and intercomparisons of accuracy of NAA by comparing results of the same sample analyzed by several laboratories

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

    2008-08-01

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

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

    International Nuclear Information System (INIS)

    Taylor, J.M.

    1997-01-01

    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

    Full Text Available In the online environment, the users have more control regarding what they want to see and this affects the advertising they are exposed to (due to the profiles created by the websites they have visited. Organizations can personalize the advertising campaigns designed at a higher level, to better meet the needs of the consumers. This paper offers an in-depth view about online advertising from 12 Romanian experts, who represent companies or digital advertising agencies and who employ this tool in order to promote themselves or to develop campaigns for their clients. The empirical research undertaken has a qualitative nature, semi-structured detailed interviews with the professionals have taken place in February-March 2015, in Bucharest. Online advertising was mostly defined by the specialists as being dynamic; and some of the attributes that characterizes this domain are measurability and personalization. Clear objectives settled, correct targeting of users, a well-established strategy and planning are the key elements that would lead to a successful online advertising campaign. The Romanian agencies offer integrated online advertising services, from research and market analysis to implementation and results’ assessment of the campaigns. The formats they have been using are: search, display, video, social media advertising, affiliated marketing and sponsorship. Most of the representatives interviewed suggest that their companies’ offers might / will change due to the dynamics of the medium. Online advertising helps the other online marketing tools perform better and develop the online presence of the companies. All the respondents have confirmed that following the introduction and great use of smartphones, their companies have adjusted the online advertising campaigns to better target the potential customers that use mobile devices. Most of the companies that invest in online advertising campaigns come from sectors such as: retail, telecom

    FRJ-2 (MERLIN), the swimming pool reactor cooled and moderated by light water, was built at the then Juelich Nuclear Research Establishment (KFA) between 1958 and 1962. In the period between 1964 and 1985, it was used for. The reactor was decommissioned in 1985. Since 1996, most of the demolition work has been carried out under the leadership of a project team. The complete secondary cooling system was removed by late 1998. After the cooling loops and experimental installations had been taken out, the reactor vessel internals were removed in 2000 after the water had been drained from the reactor vessel. After the competent authority had granted a license, demolition of the reactor block, the central part of the research reactor, was begun in October 2001. In a first step, the reactor operating floor and the reactor attachment structures were removed by the GNS/SNT consortium charged with overall planning and execution of the job. This phase gave rise to approx. The reactor block proper is dismantled in a number of steps. A variety of proven cutting techniques are used for this purpose. Demolition of the reactor block is to be completed in the first half of 2003. (orig.) [German] Der mit Leichtwasser gekuehlte und moderierte Schwimmbad-Forschungsreaktor FRJ-2 (MERLIN) wurde von 1958 bis 1962 fuer die damalige Kernforschungsanlage Juelich (KFA) errichtet. Von 1964 bis 1985 wurde er fuer Experimente mit zunaechst 5 MW und spaeter 10 MW thermischer Leistung bei einem maximalen thermischen Neutronenfluss von 1,1.10{sup 14} n/cm{sup 2}s genutzt. Im Jahr 1985 stellte der Reaktor seinen Betrieb ein. Die Brennelemente wurden aus der Anlage entfernt und in die USA und nach Grossbritannien verbracht. Seit 1996 erfolgen die wesentlichen Abbautaetigkeiten unter Leitung eines verantwortlichen Projektteams. Bis Ende 1998 wurde das komplette Sekundaerkuehlsystem entfernt. Dem Abbau der Kuehlkreislaeufe und Experimentiereinrichtungen folgte im Jahr 2000 der Ausbau der

    Full Text Available This full-scale research pavilion exercises the application of timber and polymer concrete in architectural production (Figure 1. It attempts to develop and test a new hybrid construction technique using composite joints [as introduced in Schober et al. (2014] within a modular geometric system and no need for formwork. The structure was designed and erected by students and instructors of the Digital Design and Full-Scale Fabrication seminar taught at the Institute of Architecture, University of Applied Arts Vienna. CNC milled, 3-layer spruce laminated timber boards are used for construction, which are temporarily fixed, then rigidized with polymer concrete. The cured composite node proves high structural capabilities, as polymer concrete withstands both pressure and tensile forces, and the bond between the materials is as strong as the wood itself. Compared to traditional timber construction, no metal bolting is needed for the creation of the node, while at the same time, the node geometry becomes more flexible, meaning any three-dimensional layout can be produced, as long as a temporary containment and fixation can be implemented until the chemical curing process is completed (Schober et al., 2016. The geometry is developed as an interpretation of the Zollinger (Menges et al., 2016 grid, where members originally are of twice the grid length (Figure 2 and reciprocally reliant on each other (Figure 3. Instead, every second grid cell is made a joint node when cast out with concrete, making the structural members a lost formwork at the same time (Figure 4. Double-layering each member (see detail explanation of the construction process in Section “Construction Method” below makes it possible to cast all 122 nodes of the pavilion structure separately and flat-bolt them together on-site with metal screws. Alternative fixation techniques (i.e., glue of the nodes can be tested in future. The software plugin RhinoVault is used as a design tool to

    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

    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.)

    1989-05-01

    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

    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)

    The Papapetrou equations of motion of a spinning particle do not allow the unequivocal determination of the world-line described by the particle. The motion should be completely determined in adding a supplementary condition. For macroscopic particles, characterized by the conditions of Corinaldesi-Papapetrou and Tulczyjew, moving in a Schwarzschild field we obtain additional term in the expression for the advance of perihelion. For microscopic particles we summarize the results obtained using the conditions of Weyssenhoff, Nakano, Hoenl-Papapetrou and Wessel. (author) [French] Les equations de Papapetrou decrivant le mouvement d'une particule a spin ne permettent pas de fixer de maniere univoque la ligne d'univers que parcourt la particule. Le mouvement sera completement determine en imposant une condition supplementaire arbitraire.

    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

    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.)

    Full Text Available In this essay attention is drawn to the type of response that the institutional apparatus of prison provides to the principle of rehabilitation of the convicted, as stated in Article 27 of the Italian Constitution. Particular importance is given to the representation that it is provided by professionals working in the prison, where the needs of rehabilitation often clash with those of security. The research is based on semi-structured interviews, whose content was analyzed with the technique of grounded theory. The concepts expressed by the operators were coded and placed in relation to each other, in order to obtain a coherent conceptual framework. This allowed the identification of three different categories of operators, which we called the negotiators, innovators and traditionalists, corresponding to specific cognitive maps. The results show the rehabilitation paths of the offender in prisons, according to the operators, are the result of the combination of different variables: personal resources, relationships and employment available to the inmate; the type of penitentiary, the opportunity to serve their sentences outside, and the content and quality of the relationship between the offender and institutional operators encountered whilst serving the sentence.Dans cet essai on attire l'attention sur le type de réponse que l’institution de la prison donne à la question du principe de réinsertion sociale du condamné, comme prévu par l'article n° 27 de la Constitution italienne. On accorde une importance particulière à la représentation que les travailleurs pénitentiaires ont du sujet, car en prison les exigences de rééducation sont souvent en contradiction avec celles de sécurité. Cette recherche est basée sur des entretiens semi-structurés dont le contenu a été analysé par la technique de la grounded theory. Les idées exprimées par ces professionnels ont été codifiées et mises en relation les unes avec les autres

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.)

    This research thesis reports a radiobiological study of Dianthus periclinal chimeras performed by submitting plants and plant cuttings at different physiological stages to cobalt-60 gamma irradiation under different dose conditions and rates. The effects of these treatments are studied while growing the so-processed plants and by microscopic examination of sections of irradiated meristems [French] Une etude radiobiologique de chimeres periclinales d'oeillet est effectuee en soumettant au rayonnement gamma du cobalt 60, sous differentes conditions de doses et debits de dose, des plantes entieres et des boutures a des stades physiologiques differents. Les effets des traitements sont observes au cours de la culture des plantes traitees et par l'examen microscopique de coupes des meristemes irradies. La destruction de cellules meristematiques, dans des proportions variables avec les modalites d'irradiation, provoque des modifications de structure des chimeres dont les plus frequentes sont la formation de tiges genetiquement homogenes a partir des differents genotypes existants dans la plante irradiee. Le traitement aux radiations ionisantes constitue donc une methode pratique de detection des chimeres periclinales qui, a l'image de ce qui se passe pour l'oeillet, sont tres repandues chez les plantes cultivees a propagation vegetative. Mais, comme il existe generalement plus de deux ensembles cellulaires meristematiques independants, cette methode ne permet pas, a elle seule, de definir la repartition des differents genotypes dans ces ensembles; elle doit alors etre completee par des etudes genetiques ou des marquages cellulaires tels que des mutations chlorophylliennes ou de genomes. Ainsi la structure de deux varietes d'oeillet a fleurs oranges, qui produisent, apres irradiation, des fleurs rouges et des fleurs jaunes, a ete determinee grace a l'obtention, par traitement a la colchicine, de cytochimeres 4 - 2 - 2 et 2 - 4 - 4.

    In a first part, the author gives a fast retrospective of the evaluations of the uranium deposits in the French Union. The author established a method of prospecting and studying, modifiable at all times following the experiences and the results, permitting to make the general inventory of uranium resources on the territory. The method is based on: 1 - the determination of geological guides in order to mark the most promising deposits, 2 - the definition of a methodology adapted to every steps of the research, 3 - the choice of the material adapted for each of the steps. This method, originally established for the prospecting in crystalline massifs, is adaptable to the prospecting of the sedimentary formations. (M.B.) [French] Dans une premiere partie, l'auteur donne une retrospective rapide des estimations des gites uraniferes dans l'Union Francaise.

La methode est base sur: 1 - la determination de guides geologiques afin de reperer les gisements les plus prometteurs, 2 - la definition d'une methodologie adaptee a chaque stade de la recherche, 3 - le choix du materiel adapte pour chacun des stades. Cette methode, a l'origine etablie pour la prospection en massifs cristallins, est adaptable a la prospection des formations sedimentaires. (M.B.)

    Full Text Available Present study has been constructed to determine scientific research competencies of prospective teachers and identify the extent of effect of prospective teachers’ attitudes toward scientific research and scientific research methods course on their research skills and attitudes towards research. This study has two dimensions: it is a descriptive study by virtue of identifying prospective teachers’ research skills and attitudes toward research, also an experimental study by virtue of determining the effect of scientificresearch methods course on prospective teachers’ skills and their attitudes toward research. In order to obtain the data related to identified sub-problems “Scale for Identifying Scientific Research Competencies” and “Scale for Identifying the Attitude toward Research” have been utilized. Data collection tools were applied to 445 prospective teachers. It has thus been concluded in this study that scientific research methods course had no significant effect in gaining scientific research competencies to prospective teachers and that this effect demonstrated no differentiation with respect to departments. On the other hand it has been explored that scientific research methods course had a negative effect onthe attitudes of prospective teachers toward research and that there was a differentiation to the disadvantage of prospective teachers studying at Primary Education Mathematics Teaching Department.

    1985-01-01

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

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

    The research reactor BER II is sited at the periphery of Berlin in the neighborhood of residential areas. The operational license is limited until December 31, 2019. The reactor is funded by the Federal Government (90%) and the city of Berlin (10%). The stress test has shown that the reactor is not secured against an aircraft crash (airliner or fast flying military jet), meltdown with remarkable radiological consequences to the public would be the consequence. Further hazards result from the radioactive waste transport, explosions and fires. The emergency measures cannot be considered to be sufficient. The city of Berlin would not be able to fulfill the required measures in case of a radiation accident.

    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)

  17. Seven remarkable days

    CERN Document Server

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

    2009-05-05

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

    By the end of 1998 the complete secondary cooling system and the major part of the primary cooling system were dismantled. Furthermore, the experimental devices, including a rabbit system conceived as an in-core irradiation device, were disassembled and disposed of. In total, approx. 65 t of contaminated and/or activated material as well as approx. 70 t of clearance-measured material were disposed of within the framework of these activities. The dismantling of the coolant loops and experimental devices was followed in 2000 by the removal of the reactor tank internals and the subsequent draining of the reactor tank water. The reactor tank internals were essentially the core support plate, the core box, the flow channel and the neutron flux bridges (s. Fig. 2, detailed reactor core). All components consisted of aluminium, the connecting elements such as bolts and nuts, however, of stainless steel. Due to the high activation of the core internals, disassembly had to be remotely controlled under water. All removal work was carried out from a tank intermediate floor (s. Fig. 2). These activities, which served for preparing the dismantling of the reactor block, were completed in summer 2001. The waste parts arising were transferred to the Service Department for Decontamination of the Research Centre. This included approx. 2.5 t of waste parts with a total activity of approx. 8 x 10{sup 11} Bq. (orig.)

    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.

    Attendees are welcomed to the conference. The general scope of the problem is touched on, and the driving point is made, that the development of new technology is necessary to meet the environmental restoration goals for the Hanford Reservation with a reasonable expenditure of funds and resources. If present technology in treating radioactive waste has to be applied to the wastes prior to final disposal, then the processing costs, and the resultant disposal costs, because of the volume of material to be disposed of, will be tremendous. This conference brings together researchers from national laboratories, universities, and industry to present the scope of the problem, the present status of separation science, and to encourage new technological development

    This special issue contains the proceedings of the 37th Annual Meeting of the National Council on Radiation Protection and Measurements held 4-5 April 2001 in Arlington, Virginia. The theme of the meeting was 'Fallout from Atmospheric Nuclear Tests-Impact on Science and Society.' Between 1945 and 1980, over 500 nuclear weapons tests were conducted in the atmosphere by the United States, Russia, United Kingdom, France, and China. This practice resulted in the release of large quantities of radioactive materials, which dispersed widely in the atmosphere and deposited on Earth's surface. The measurement of these so-called 'fallout' radionuclides in air, soil, and water and the evaluation of the transfer of these materials to the human body became a significant scientific endeavor. Many national and international monitoring projects were initiated, and extended studies were made of the fallout behavior. An historical overview of the testing and resultant monitoring programs, fallout mechanisms, and estimates of the resultant deposition of fallout is presented in the first paper in this Symposium. University and national laboratory scientists conducted a large number of research programs during the course of weapons tests and fallout. This research resulted in substantial improvements in low-level radioactivity metrology as well as significant advances in the understanding of atmospheric, ecological, and oceanographic processes. Many of these results are still highly pertinent to present-day environmental radiation issues related to the cleanup of contaminated sites, the decommissioning of contaminated facilities, and the assessment of accidents such as occurred at Three Mile Island and at Chernobyl. The results of these investigations were published in thousands of research papers and presented at a number of international conferences held over the processes. The radionuclides served as tracer materials in this regard. The initiation of research on radioactive fallout

  7. Editorial - a remark you made

    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

    For more than 60 years, research reactors have been centres of innovation and productivity for nuclear science and technology programmes in 67 countries around the world. Research reactors provide a multidisciplinary environment to catalyse scientific, industrial, medical and agricultural development. They are facilities for nuclear education and training of young scientists and technicians, and they can contribute to the development of nuclear power programmes. According to the IAEA Research Reactor Database, there are 246 research reactors currently in operation in 55 countries, and close to 30 new research reactor projects are at different stages of implementation. Many of the operating reactors are several decades old and face ageing management issues. These reactors must be operated and maintained with due regard to safety and security. Some reactors face challenges with sustainable supply of fresh fuel. Others are looking to improve utilization, which is linked to justifying adequate resources for operation, maintenance and refurbishment. As some of the fuel return programmes are expected to wind down in the near term, the community will need to find solutions for spent fuel and waste management. And taking into account the large number of reactors, about 140, no longer in operation, as well as ageing reactors coming to the end of their lifecycles, decommissioning is an important area of sharing experience and best practice. You will have an opportunity to discuss these and other issues over the course of the conference.

    This report covers the MHD power generation research and development project which has been under way for 7 years since fiscal 1966, and contains guidelines to follow in the next 3 years during which studies will continue toward the consummation of the project. Subjected to research and development under this project are the development of superconductive magnets and helium refrigeration/liquefaction equipment, clarification of the power generation characteristics of the 1,000kW-class MHD (magnetohydrodynamic) power generator and of a test machine designed for a long-term operation, etc. Since they contain many basic studies, the efforts are being exerted primarily by the Electrotechnical Laboratory. In the research and development of MHD power generation characteristics, a power generation experiment is conducted through oxygen combustion in a hot wall channel, with the combustor and insulation against the Hall voltage improved. In this test, a maximum output of 1,182kW is achieved under the conditions of a flow rate of 2.9kg/s, a thermal input of 24.6MW, and a flux density of 3.2T. Since there are some problems to solve in connection with the stability of MHD power generation characteristics, durability of the MHD power generation channel, characteristics of heat exchanger system, measures for NOx reduction, etc., some more deliberation is necessary before taking the next research and development step.

    First, the authors define the operation and organisation lay-out of the research reactors. This out lay is then used as a basis for an examination of the conception, realisation and exploitation of irradiation devices. They then analyse the different operations carried out in placing an irradiation device in the reactor. They point out that the time necessary for decision of construction, conception, for material provision, for construction, out-of-pile tests and security examination is in general longer than the irradiation time. To minimize this time they advise a closer collaboration between the personnel of the experimentation laboratory and the reactor personnel for the conception of the design. They think it would be preferable to construct the prototypes in the research centre and leave the fabrication of small series to the industry. The methods used for the in-pile operation of the device are also indicated. Considering the evolution of the construction techniques they mention that the requirements for the irradiation conditions are put higher and higher (reactor stability and homogeneity). Also described are the performances of the main irradiation devices in operation in research reactor in the C.E.A. (authors) [fr

    Directory of Open Access Journals (Sweden)

    Lorenzo Pubblici

    2017-09-01

    Full Text Available Objective: For decades the slave trade was very lucrative for the Italian merchants who travelled to the East. The formation of the Mongol Empire, and the economic and demographic growth occurred in Europe, have contributed to the increase of both, the demand of slaves and the supply human merchandise. Trade increased with the simultaneous increase in the number of journeys of western merchants to the East. The creation of a structured trading system on the Black Sea coast has allowed Genoa and Venice to strengthen their trade relations with the dominant centers of power in loco: the Golden Horde of the Mongols and the Mamluks of Egypt. Materials: This article is a preliminary critical mapping of a larger project I’m working on, and which aims to explore the relationship between Italian commercial immigration and the slave trade in the Venetian settlement of Tana, situated in the mouth of the Don, and representing the easternmost outpost of all Latin Trading System in the East in the 13th and 14th centuries. Based on a solid historiographical tradition and the Venetian documentary sources, I’m trying to restore the perception of a slave in the unique context of the Golden Horde, where the western urban mercantile and the eastern nomadic factors came into contact. Results and novelty of the research: While many of the conclusions of this research are still to be confirmed, a primary investigation has shown that slaves were not only the primary and most profitable resource for Italian merchants, but also the most direct and effective means to penetrate and understand an ethnic and culturally stranger context.

    Full Text Available The article deals with some methodological topics related to researches on drug phenomena. The main consideration pertains to that kind of “crime without victim” that is largely hidden (dark figure. The solutions adopted to approach these and other problems include the rigorous logical and semantic definition of the objects and the use of specific analysis criteria taken from other disciplines, like demography and urban topography. Official statistics figures must be corrected by specific criteria; on the one hand by the statistical projection of the outcome data, and on the other hand by the case studies. Cet article aborde le sujet des méthodes de recherche qui doivent être utilisées par les études empiriques des phénomènes liés à la drogue. À ce propos il faut avant tout étudier ce phénomène en tant que « crime sans victime » qui alimente le chiffre noir. Les solutions adoptées pour essayer de résoudre ce problème particulier et d’autres problèmes typiques incluent la rigureuse définition logique et sémantique des termes objet d’étude et l’utilisation de critères d’analyse empruntés à d’autres disciplines, notamment à la démographie et à la topographie urbaine. Les données provenantes des statistiques officielles doivent être corrigées de la façon suivante : d’un côté par la projection statistique des résultats et, de l’autre côté, par l’étude de cas.L’articolo discute alcuni elementi di metodo da tenere presenti nell’ambito dello studio dei fenomeni connessi alla droga. Prioritaria al riguardo è la considerazione di tale fenomeno criminale come “reato senza vittima” e la preponderante presenza della cifra oscura. Le soluzioni adottate per bilanciare questi e altri problemi tipici includono la rigorosa definizione logico/semantica dei termini oggetto di studio e il ricorso a criteri di analisi mutuati da altre discipline, su tutti la demografia e la topografia urbana.

    Deep eutectic solvents (DESs) are basically molten salts that interact by forming hydrogen bonds between two added components at a ratio where eutectic point reaches a melting point lower than that of each individual component. Their remarkable physicochemical properties (similar to ionic liquids) with remarkable green properties, low cost and easy handling make them a growing interest in many fields of research. Therefore, the objective of pursuing this study is to analyze the potential of alcohol-based DES as an extraction medium for rotenone extraction from Derris elliptica roots. DES was prepared by a combination of choline chloride, ChCl and 1, 4-butanediol at a ratio of 1/5. The structure of elucidation of DES was analyzed using FTIR, {sup 1}H-NMR and {sup 13}C-NMR. Normal soaking extraction (NSE) method was carried out for 14 hours using seven different types of solvent systems of (1) acetone; (2) methanol; (3) acetonitrile; (4) DES; (5) DES + methanol; (6) DES + acetonitrile; and (7) [BMIM] OTf + acetone. Next, the yield of rotenone, % (w/w), and its concentration (mg/ml) in dried roots were quantitatively determined by means of RP-HPLC. The results showed that a binary solvent system of [BMIM] OTf + acetone and DES + acetonitrile was the best solvent system combination as compared to other solvent systems. It contributed to the highest rotenone content of 0.84 ± 0.05% (w/w) (1.09 ± 0.06 mg/ml) and 0.84 ± 0.02% (w/w) (1.03 ± 0.01 mg/ml) after 14 hours of exhaustive extraction time. In conclusion, a combination of the DES with a selective organic solvent has been proven to have a similar potential and efficiency as of ILs in extracting bioactive constituents in the phytochemical extraction process.

    Further details are provided of a soon-to-be published dialog [Phys. Fluids 29 (July, 1986)] which discussed the role of the small scales in fluid clump theory. It is argued that the approximation of the clump lifetime which is compatible with exponentially rapid separation of adjacent orbits is inappropriate for the description of the dynamically important large scales. Various other remarks are made relating to the analytic treatment of strong drift-wave-like turbulence

    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...

    The author correlates and analyses the experimental data obtained over the past two or three years regarding the biological effects of neutrons and high-energy protons, and shows that it is a matter of prime concern for present-day radiobiology to investigate the relative biological effectiveness of the various types of radiation under various irradiation conditions and the reasons for the qualitative differences in their effect on the animal organism. Attention is drawn to the need for more research into the combined effect of various types of radiation and other agents. Specific examples are cited to demonstrate the main progress achieved in studying the prophylaxis of radiation injury induced by neutrons or high-energy protons and to show the contribution such research can make towards understanding the specific way in which various types of radiation act.

    Checking on radioactive preparations for medical use is complicated by difficulties due to the radioactivity, the instability and the methods of using these solutions. In effect it is necessary, in order to draw up a practicable set of rules governing such checks, to know both the method of preparation and the properties of the radioelement, as well as special and often contradictory features of its use. These tests fall into three categories: physical, chemical and biological. Preparations of chromium 51, iron 59 and arsenic 76 have been dealt with in recent studies. In each case special tests were necessary, and these will be described in this paper. The practice of these tests is of twofold interest: firstly they provide a maximum guarantee to the user, and secondly they guide the chemist in his manipulations, immediately and thoroughly. (author) [French] Le controle des preparations radioactives a usage medical est complexe par suite des difficultees dues a la radioactivite, a l'instabilite et aux modalites d'utilisation de ces solutions. En effet, l'etablissement justifie d'un protocole de controle necessite la connaissance aussi bien du mode de preparation, que des proprietes du radioelement et des particularites parfois contradictoires de son emploi. Ces controles sont de trois ordres physiques, chimiques, biologiques. Des etudes recentes ont porte sur des preparations de chrome 51, de fer 59, d'arsenic 76. Dans chaque cas, il est apparu necessaire de pratiquer des controles particuliers qui seront exposes dans la communication. La pratique de ces derniers presente un double interet; d'une part, ils assurent a l'utilisateur un maximum de garantie, d'autre part, ils orientent le chimiste dans ses mises au point, immediatement et de facon approfondie.

    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!

    After the new radiation protection ordinance has come into effect with July 20th, 2001 the approval process for application of radiation substances or ionizing radiation in medical research changed considerably with respect to the responsibility of the Federal Office for Radiation Protection as the approval authority, the participation of an approved ethic committee, the inclusion of an expert for medical physics for planning and execution of the study as well as stricter regulations for cover clause. On the contrary, existing regulations have been facilitated since the effective dose limit for volunteers has been increased from 10 to 20 mSv and a central procedure for approval of multicenter studies has been introduced. Moreover, the application of radioactive substances or ionizing radiation for research in people without or with restricted legal capacity is no more totally prohibited. At present, changes of the radiation protection ordinance and the atomic law cover clause ordinance with respect to medical research are in discussion. (orig.) [German] Nach In-Kraft-Treten der neuen Strahlenschutzverordnung vom 20.07.2001 ergeben sich wesentliche Aenderungen des Genehmigungsverfahrens fuer die Anwendung radioaktiver Stoffe oder ionisierender Strahlung in der medizinischen Forschung bezueglich der Zustaendligkeit des Bundesamts fuer Strahlenschutz als Genehmigungsbehoerde, der Einschaltung einer akkreditierten Ethikkommission, der Hinzuziehung eines Medizinphysik-Experten bei der Studien-Planung und -Anwendung sowie verschaerfter Regelungen zur Deckungsvorsorge. Eine gewisse Erleichterung bisher bestehender Regelungen ist in der Erhoehung des Grenzwerts der effektiven Dosis fuer Probanden von 10 auf 20 mSv sowie dem zentralen Genehmigungsverfahren fuer Multizenter-Studien zu sehen. Ausserdem ist eine Anwendung radioaktiver Stoffe oder ionisierender Strahlung in der Forschung an geschaeftsunfaehigen und beschraenkt geschaeftsfaehigen Probanden nicht mehr voellig

    Following the Kyoto demands the budgets allocated to the renewable energies researches are more and more important. Among these energies the biomass is very popular in Japan because it does not increase the carbon dioxide level in the atmosphere. Since the years 1990 the Japan implemented three ministries to promote the biomass energy in the country.

    Full Text Available One of the more challenging issues in epidemiological research is being able to provide an unbiased estimate of the causal exposure-disease effect, to assess the possible etiological mechanisms and the implication for public health. A major source of bias is confounding, which can spuriously create or mask the causal relationship. In the last ten years, methodological research has been developed to better de_ne the concept of causation in epidemiology and some important achievements have resulted in new statistical models. In this review, we aim to show how a technique the well known by statisticians, i.e. standardization, can be seen as a method to estimate causal e_ects, equivalent under certain conditions to the inverse probability treatment weight procedure.

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

    Full Text Available Les mobilités pendulaires semblent être en augmentation en Europe depuis une dizaine d’années. Cette croissance du temps passé à se déplacer amène à remettre en question la conjecture de Zahavi et apparaît relativement inexplicable en regard du paradigme classique de l’acteur rationnel traditionnellement utilisé dans le champ des transports. Si, dans la littérature, les temps de déplacements sont principalement expliqués par le contexte résidentiel, la forme urbaine et le travail, ce cadre explicatif ne dit rien des processus de décision eux-mêmes qui amènent aux pendularités intensives.À partir d’une enquête qualitative menée auprès de pendulaires français, suisses et belges, cette contribution propose d’analyser les arbitrages et les éléments déterminants des processus de la grande pendularité. Les mobilités quotidiennes pendulaires apparaissent comme le résultat de compromis entre activité professionnelle, attachement résidentiel et choix de vie et prennent ainsi la forme de stratégies de conciliation entre vie privée et vie professionnelle. Ces mobilités spatiales permettent alors paradoxalement la préservation des ancrages résidentiels, sociaux et familiaux.Roots and wings. Long-distance commuting patterns, or how to conciliate professional and personal lifeLong-distance commuting patterns appear to be increasing in Europe over the last ten years. These raising mobility patterns lead to reappraise the Zahavi conjecture and appear largely inexplicable by the classical rational actor paradigm traditionally used in transportation research. In literature, commuting is mainly explained by residential contexts, urban forms and job. Nevertheless this theoretical frame says little about the decision-making processes themselves. Based on a qualitative survey conducted in three European countries - France, Belgium and Switzerland – among a population of high commuters, this paper proposes an analysis of

    More than forty years have passed since the discovery of Mossbauer effect; one of the most brilliant findings in modern physics. This effect proved itself to be the powerful tool in almost all disciplines of the natural sciences and technology. Its unique feature is that it gives the possibility to get the results which cannot be obtained by any other physical methods. Mossbauer effect has been used as a key to unlock some basic physical, chemical and biological phenomena, as a guide for finding the new ways of solving applied scientific and technical problems of electronics, metallurgy, civil engineering, and even fine arts and archaeology. Very few scientific techniques can claim entry into as many countries as Mossbauer spectroscopy. Due to its wide application in an education and research processes the community of Mossbauer spectroscopists extends to almost 100 different countries. Laboratory equipment necessary for conducting gamma resonance spectroscopy, do not require large investments, premises, personnel. The spectrometer is rather small in size and could be installed on the ordinary laboratory table. That is why Mossbauer effect is widely used at numerous Universities all over the world as an universal instrument for tuition and research

    The electron beam welding of metals is performed by the travelling of the focusing point along the junction of two pieces to be connected. Welding parameters are the electron gun power W, the value of the electron impact surface S, the welding speed s. From the beginning of our research in 1954, the preponderant part played by specific power W/s on the shape of the welded zone and the penetrating depth, became evident. A more methodical research has been undertaken in the laboratories of C.E.N. under the patronage of Professor CHAUDRON, in order to define in a better way the importance of the different welding parameters and to determine their influence on the metallurgical qualities of welded assemblies. This research induced us to define an electron gun adapted as well as possible to the performance of weldings, not only from the point of view of behaviour, especially during the passage from the atmospheric to a low pressure at 10{sup -5} Torr, necessary for the carrying out of a welding, but also from the point of view of adjustment conveniences of the different welding parameters, indispensable to the intended research work. The variations of welding parameters show that the shape of the molten zone turns from a circle segment to that of a very high triangle, which implies a continual change of the mode of heat transmission. Tests have been made, in order to confirm this way of looking, especially in order to achieve isotherms in dynamic operating and also the comparison of these isotherms with that recorded while using a method of argon arc welding. The thermal balance of energy supplied to the part, the necessary welding energy, and the energy loss (through conduction, radiation and evaporation) has also been established. These results proved that almost the whole of energy has been used for melting, that the different losses are negligible and that heat transmission can not occur by thermal conduction through the part during 'welding' time, when operating

  8. Concluding Remarks and Future Outlook

    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…

    The authors successively examine the different research reactors in use in the French C.E.A. Nuclear Centres. They trace briefly their histories, describing how they have been used up to the present, and how they have been adapted to changes in programme by means of certain modifications. They also describe the reasons which have led to the elaboration of the project for the new reactor Osiris. Zoe, the oldest reactor in the CEA, has been in service in the Centre de Fontenay-aux-Roses since 1948. It is used mainly for measurements of absorption cross-sections in graphite, and for various short irradiations which do not require high fluxes. The reactor EL 2, in service since 1952, was used for the first studies on gas cooling. It has also been widely used for the production of radioisotopes and for a large number of experiments in the fields of physics, metallurgy and physical chemistry. The ageing of certain elements of the reactor has led to the decision to close it down in the near future The reactor EL 3 has been widely used for experiments in physics and in the investigation of fuels. The possibilities of the reactor in fast neutron irradiations will be considerably improved by the adoption of a new type of core (the 'snow crystal' structure). Triton-I, a 2 MW swimming-pool reactor, is used for the most part for fast neutron and gamma irradiations. The modifications being carried out on it at present should result in an increase in the power of the reactor up to 4 or 5 MW. In a neighbouring compartment is housed Triton-II which is of the same general structure, as Triton-I, but whose maximum power is 100 kW. Triton-II is used solely for studies on shielding. Melusine, a 2 MW swimming-pool reactor, has been in use in the Centre d'Etudes Nucleaires de Grenoble since 1959. It has supported a very high programme concerned mainly with solid state physics, fundamental research into refractory fissile materials and special graphites, and the study of the behaviour of

    In the first part of the report, the author attempts to draw an historical scheme of successive research working hypotheses in radiobiology since 1924. Less than a generation ago the effect of radiation exposure were viewed as being direct, immediate, irreparable and unmodifiable. Now it is generally accepted that radiation lesion can also be indirect, delayed, reparable and often modified with appropriate chemical or biochemical treatment. It was however in 1962-1964 that came the decisive breakthrough in radiobiology with the discovery that the cell possesses a natural active self-defense mechanism against whatever stress would affect the integrity of the genetic message contained in the DNA structure itself. The existence of what could be considered as a fourth DNA function i.e. self-repair by enzymatic action under genetic control-brings at least to radiobiology the missing molecular biology basis it needed to get out of its 'phenomenological night' after abandon of the generalization of Lea's theory through lack of experimental evidence. In the second part, which is a prospective one, the author tries to set an enlarged synthesis considering the possible role of DNA repair system not only in cell survival - in presence or absence of dose modifiers or mutagens - but also in the artificial and natural evolution of biological system exposed to sub-lethal doses of radiation. Most recent data from the literature fit well with what must be still considered as a general working hypothesis. Studies dealing with phenotypic and genotypic characters linked with the acquisition of gamma and UV radiation resistance in 'Escherichia coli K12' has been started by the author, in collaboration with O. Tremeau, in order to bring a new experimental contribution in this respect.

    The VGB research project was to examine and characterize various, operation-induced impacts on the crack formation in stabilized austenitic steels, caused by intercrystalline stress corrosion cracking as a result of sensitization after chromium depletion at the grain boundaries. The results of this project as well as available operating experience show that the measures taken so far for the future operation of the German BWR plants, for avoiding in these plants intercrystalline stress corrosion cracking, correspond to the state of the art and achieve the wanted purpose. These measures are: use of optimized material W-No. 1.4550 with reduced carbon contents; use of optimized welding techniques for reducing the heat input and the welding shrinkage (cold deformation.); optimized preparation of welding work in order to avoid shape defects during welding (eg. edge misalignment, defective mash welds); reduction of tensile stresses occurring during welding; compliance with the recent VGB water chemistry code.

Aus den Forschungsergebnissen dieses VGB-Programms sowie den bisher vorliegenden Betriebserfahrungen ist festzuhalten, dass die bisher durchgefuehrten Massnahmen fuer den zukuenftigen Betrieb der deutschen SWR-Anlagen zur Vermeidung von interkristalliner Spannungsrisskorrosion zielgerichtet waren und dem heutigen Wissensstand entsprechen. Diese Massnahmen sind: 1. Einsatz von optimiertem Werkstoff W.-Nr. 1.4550 mit abgesenktem Kohlenstoffgehalt; 2.

    The authors discuss the difficulties encountered in the exploration of a typical deposit in the Nord-Limousin, using the resistivity measurement method. In the zone in question the over-thrust was very variable and difficult to predict. The uraniferous deposits had two types of aspect, the passage from one to the other being often very sudden: long thin veins without gangue; short and thick lens-shape deposits which were strongly contaminated by clay towards their edges. After several unsatisfactory attempts, the device known as the 'rectangular map' was adopted and gave an acceptable structural representation rapidly and cheaply. For the placing of the probes however, methods are required which are more refined and sensitive. It is in any case useless to expect to obtain a satisfactory representation and a sufficient accuracy using a single technique; especially in the region under consideration. (author) [French] Les auteurs exposent les difficultes rencontrees pour l'exploration, par la methode des mesures de resistivite, d'un gisement type du Nord-Limousin: il s'agissait d'une zone a recouvrement tres variable et difficilement previsible. Les occurences uraniferes y affectaient deux facies passant brutalement de l'un a l'autre: longs filonnets minces et sans gangue; lentilles courtes et puissantes avec alteration argileuses tres etendue aux epontes. Apres plusieurs essais peu satisfaisants, le dispositif dit 'carte des rectangles' a ete adopte pour obtenir rapidement et a bon compte un schema structural suffisant. Mais des methodes plus fines et plus sensibles sont necessaires pour guider l'implantation des sondages. Il est d'ailleurs vain d'esperer trouver a la fois la representativite d'ensemble et la precision, dans l'utilisation d'une seule technique, surtout dans la region envisagee. (auteur)

    The present report gives the actual point of studies on vitrification of concentrated solutions of fission products. An active cell, giving glasses in crucibles, permitted to study various glass compositions. The leaching rate from the glass raises 1 to 2 10{sup -7} g of glass/cm{sup 2}/day. Activity loss by volatility during vitrification remains weak and often below 0.1 per cent of total activity. Off gas cleaning is made easier by presence of filter which is compound of granules including iron oxide. After saturation the content of this filter can be melt. Moreover different processes are in experimentation for a more important production. Daily 72 liters of solution containing tracer activity are treated in a continuous calcination and vitrification plant. The loss in {sup 106}Ru is still important and a modification of installation has been necessary. A pot vitrification plant is in study. In order to reduce cost of processing the possibility to pour glass after melting is actuality in study. A production set of very active glass is also in project. (authors) [French] Le present rapport fait le point des etudes menees sur la vitrification des solutions concentrees de produits de fission. Une installation active, produisant des verres en creusets, a permis d'etudier plusieurs compositions de verres. Le taux de perte d'activite par lixiviation a l'eau atteint 1 a 2 10{sup -7} gramme de verre/cm{sup 2}/jour. Les pertes d'activite par volatilite au cours de la cuisson restent faibles et souvent inferieures a 0,1 pour cent de l'activite totale. L'epuration des gaz de cuisson est facilitee par la presence d'un filtre a granules riches en oxyde de fer, dont le contenu peut etre fondu apres saturation. Differentes techniques sont, en outre, en experimentation pour une production plus importante: Une installation de calcination et vitrification continue traite 72 litres par jour de solution contenant une activite traceur.

    Investigations have shown that even the very first forest generation on spoil banks already have high vitality. However, it is well known that pioneering terrestrial ecosystems have a high water and material turnover dynamics which will quickly influence the soil at that site but is not an indication of the development of a stable ecosystem. Long-term measurements were therefore made in oak forest ecosystems on quaternary spoil bank sands in order to achieve a quantification (Boxberg: Q. rubra L., 2 years; Kleinleipisch: Q. rubra L., 21 years; Annahuetter: Q. rubra L., 63 years). The results were compared with a virgin soil reference site (Neusorgefeld: Q. rubra L., 41 years). [German] Seit Jahrzehnten praegen Braunkohlentagebaue das Landschaftsbild und den Wasserhaushalt der Niederlausitz. Bislang wurden ca. 770 km{sup 2} ueberwiegend forstlich genutzter Flaechen devastiert und auf 2.100 km{sup 2} rund 9,5 Mrd. m{sup 3} statischer Grundwasservorraete entnommen. Im Zuge der seit 1990 drastisch verringerten Kohlefoerderung und forcierten Bergbausanierung erreicht die Rekultivierungsflaeche zwischenzeitlich rund 450 km{sup 2}, wobei die forstliche Folgenutzung mit 60% der Flaeche dominiert. Zahlreiche wachstumskundliche Untersuchungen belegen, dass sich bereits in der ersten Waldgeneration auf Kippe wuechsige und vitale Bestaende etablieren. Vegetations- und ertragskundliche Parameter wie z.B. Artenzusammensetzung, Naehrstoffversorgung, laufender Zuwachs oder Vorratshaltung sind jedoch per se noch keine hinreichenden Kriterien zur Einschaetzung der Entwicklungsdynamik und damit des angestrebten Rekultivierungserfolgs. Bekannterweise zeichnen sich im Aufbau befindliche terrestrische Oekosysteme generell durch eine ausgepraegte Wasser- und Stoffdynamik aus, welche im Zuge bodengenetischer Prozesse meist eine rasche Standortveraenderung bewirkt. Da das Standortpotential zum Rekultivierungszeitpunkt nicht prognostiziert werden kann, ist offen, ob sich bereits in der

    One of the main objectives of CANMET's Energy Research program is to develop the technologies required to conserve and to increase the supply of liquid fossil fuels in Canada to bridge the gap that exists between domestic supply and demand (both internal demand and export opportunities). The Energy Research Laboratories (ERL) respond to this R D objective on matters related to the upgrading of oil sands; heavy oil and synthetic crude production; coal/bitumen coprocessing; and improved oil and gas domestic heating furnaces. Another major objective is to develop the technologies to burn fossil fuels, mainly coal, under environmentally acceptable conditions; ERL responds to this objective through research in the areas of coal combustion and gasification. This report summarizes the activities of ERL during the fiscal year 1984/85. A recent reorganization of the ERL is summarily described. The total expenses of ERL in 1984/85 were 169 persons/year, $6.375 million in salaries, $3.499 million in operating costs, $2.740 million in capital investments, and $10,000 million in contracts. Included in the report are listings of employees, patents, publications, technical committees, and contracts. 2 figs., 2 tabs.

    This research thesis reports a study in which the author examined whether modifications of sodium flows noticed during the adaptation to environments displaying a different salinity would result from a hormonal determinism. The author first reports in vitro studies which aimed at determining whether the neuro-hypophysis hormone was itself able to explain noticed observations. Knowing that for mammals, a sodium-rich regime results in a resting mineralotropic function of the adrenal cortex, the author studied, by in vivo administering of aldosterone, whether the sodium flow variations through the animal skin due to a prolonged stay in a high salinity bath would result from a similar mechanism. [French] Chez Rana esculenta, la conservation prolongee dans une solution de NaCl isotonique au plasma d'une part, dans de l'eau desionisee d'autre part modifie les flux de sodium a travers la peau mesures dans une solution diluee de NaCl (25 μg Na/ml). La conservation dans une solution de NaCl 7 0/00 entraine: une diminution du transport actif de sodium a travers la peau, in vivo et in vitro et d'autre part une augmentation de la diffusion passive de cet ion a travers la peau (flux de sortie augmente). La conservation dans un milieu appauvri en Na entraine les modifications inverses (augmentation du flux d'entree de sodium a travers la peau, flux net nul). Par ailleurs une forte salinite du milieu exterieur entraine une surcharge sodique plasmatique et tissulaire, la conservation dans un milieu pauvre en sodium une depletion sodique plasmatique et tissulaire. In vitro, l'ocytocine ne peut pas, a elle seule, rendre compte des modifications du transport actif de sodium a travers la peau des animaux conserves au prealable dans des milieux de salinite differente. Par contre, in vivo, des injections repetees d'aldosterone provoquent une augmentation du flux d'entree de sodium a travers la peau des animaux conserves dans la solution de NaCl a 7 0/00 comparable a celle observee chez

    In the fall of 1978 six houses in Sweden were found to have unacceptably high radon concentrations. These houses were built on land where shale ash had been used as landfill. Radon levels were reduced significantly by increasing ventilation rates or by removing the shale ash. In five houses built of aerated concrete based on alum shale attempts are being made to reduce the radon concentration by papering the walls with aluminum foil. Further work is being done on the relation between elevated activity in rock and soil and indoor concentrations of radon, and on the exhalation of radon from building materials

  13. Remarks about the displaced spectra techniques

    International Nuclear Information System (INIS)

    Behringer, K.; Pineyro, J.

    1989-01-01

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

    Rats conditioned to take their dally meal between midnight and 2 a.m. are given at midnight, by stomach tubing, 0,5 mg 4-{sup 14}C-cholesterol, and are sacrificed in the following hours. During the most active phase of intestinal absorption, specific radioactivities of free and esterified liver cholesterol and of serum cholesterol are practically equal. Consequently, captation of absorbed cholesterol by the liver is not detectable. The results obtained exclude, on the other hand, the possibility that the lungs might play a similar role. The problem of the fate of chylomicron cholesterol is discussed. In order to avoid any ambiguity in this discussion, we have determined the concentration and specific radioactivity of free and esterified cholesterol in chylomicrons and lymph obtained by continuous drainage of chyle. 5 p. 100 of the radioactive cholesterol of chyle are found in lymph: in chylomicrons, the radioactivity of free cholesterol is higher than that of esterified cholesterol.

En consequence, la captation par le foie du cholesterol d'absorption n'est pas decelable.

    2011-01-01

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

  18. Remarks on theoretical hot-atom chemistry

    International Nuclear Information System (INIS)

    Inokuti, Mitio

    1993-01-01

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

    Lymphocyte-predominant Hodgkin disease (LPHD) is rare and has a natural history different from that of classic Hodgkin disease. There is little information in the literature regarding the role of chemotherapy in patients with early-stage LPHD. The objective of this study was to examine recurrence free survival (RFS), overall survival (OS), and patterns of first recurrence in patients with LPHD who were treated with radiotherapy alone or with chemotherapy followed by radiotherapy. From 1963 to 1996, 48 consecutive patients ages 16-49 years (median, 28 years) with Ann Arbor Stage I (n = 30 patients) or Stage II (n = 18 patients), very favorable (VF; n = 5 patients) or favorable (F; n = 43 patients) LPHD, according to the European Organization for Research and Treatment of Cancer and Groupe d'Etude des Lymphomes de l'Adulte (EORTC-GELA) criteria, received radiotherapy alone (n = 37 patients) or received chemotherapy followed by radiotherapy (n = 11 patients). The percentages of patients with VF disease (11% vs. 9% in the radiotherapy group vs. the chemotherapy plus radiotherapy group, respectively) or F disease (89% vs. 91%, respectively) within the two treatment groups were similar (P = 1.00). A median of three cycles of chemotherapy with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) or with mitoxantrone, vincristine, vinblastine, and prednisone (NOVP) was given initially to six patients and five patients, respectively. A median total radiotherapy dose of 40 grays (Gy) given in daily fractions of 2.0 Gy was delivered to both treatment groups. The median follow-up was 9.3 years, and 98% of patients were observed for > or = 3.0 years. RFS was similar for patients who were treated with radiotherapy alone and patients who were treated with chemotherapy followed by radiotherapy (10-year survival rates: 77% and 68%, respectively; P = 0.89). The OS rate also was similar for the two groups (10-year survival rates: 90% and 100%, respectively; P = 0

    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.

    Since 1954, at the Commissariat a l'energie atomique, geophysics and geochemistry have been added to routine geological surveying and radiometric observations. Geophysical prospecting reveals the tectonic structures linked with French uranium deposits and gives an idea of favorable zones. Geochemistry adds to the geophysical indirect methods further details on the distribution of uranium traces in the soils. This method is direct and specific. Uranium assay in waters and alluvial deposits find its use in preliminary exploration.

    Full Text Available Filling potteries missing parts with plaster raises now complex problems during the de-restoration treatments. Ceramics restorers have recurrently questions on the use of plaster in the field of archaeological ceramics restoration. Some researches point to the choice of other filling materials. At the present time other methods can be devised by proposing plaster replacement by a lightened composite material: syntactic foams and pastes.Le comblement des lacunes des poteries à partir du plâtre pose actuellement des problèmes complexes lors des traitements de dérestauration. Les restaurateurs de céramiques s'interrogent de manière récurrente sur l'utilisation du plâtre dans le domaine de la restauration des céramiques archéologiques. Des recherches s'orientent vers le choix d'autres matériaux d'obturation. Actuellement, d'autres méthodes peuvent être mises en place en proposant le remplacement du plâtre par un matériau composite allégé, les mousses et les pâtes syntactiques.

  10. Chandra Sees Remarkable Eclipse of Black Hole

    Science.gov (United States)

    2007-04-01

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

  11. La territorialisation des politiques environnementales

    Directory of Open Access Journals (Sweden)

    Amédée Mollard

    2010-10-01

    Full Text Available Le point de départ de cet article est la grande variabilité de la pollution nitrique diffuse de l’eau due à l’agriculture. Celle-ci dépend en particulier du climat, des types de sol et des systèmes de production agricole. Nos recherches réalisées de façon interdisciplinaire à partir de deux sites différents en France, montrent que cette hétérogénéité spatio-temporelle conditionne les pratiques agricoles mises en œuvre pour réduire la pollution au niveau de la norme admise. De ce fait, les pratiques les plus « coût-efficaces » diffèrent d’un territoire à l’autre, en fonction des caractéristiques locales. Ces résultats mettent donc en évidence une efficacité potentielle d’une territorialisation des politiques publiques. En théorie, de telles politiques sont considérées comme optimales par les économistes, car elles incitent les agents à moduler leurs efforts en fonction de la sensibilité du milieu. Mais, selon les études empiriques, cet avantage serait annulé par un coût élevé de mise en œuvre, de contrôle et de surveillance. Pour maintenir leur avantage sur des politiques uniformes, les politiques territorialisées devraient être mises en œuvre à un niveau spatial optimal. Un tel niveau devrait au minimum atteindre un compromis entre l’économie réalisée grâce à une modulation adaptée aux conditions locales et les sur-coûts dus à la décentralisation des solutions mises en œuvre. Cet article analyse la pertinence d’une prise en compte de ces spécificités par des politiques territorialisées. L’efficacité d’une régulation différenciée de la pollution nitrique est étudiée ici en évaluant l’importance de la variabilité spatiale des paramètres physiques et des coûts de la territorialisation.The paper starts with the wide variability of nonpoint water nitrogenous pollution generated by agriculture. This variability depends especially on climate, soil types and farming

  3. The globalization of epidemiology: introductory remarks.

    Science.gov (United States)

    Pearce, Neil

    2004-10-01

    We are all living in the era of globalization, and like it or not, it is going to change the way we practice epidemiology, the kinds of questions we ask, and the methods we use to answer them. Increasingly, pubic health problems are being shifted from rich countries to poor countries and from rich to poor populations within Western countries. There is increasing interest and concern about the situation in non-Western populations on the part of Western epidemiologists, with regards to collaborative research, skills transfer, and 'volunteerism' to enable the 'benefits' of Western approaches to epidemiology to be shared by the non-Western world. However, most existing collaborations benefit Western epidemiologists rather than the countries in which the research is conducted. Even when research in non-Western populations is conducted as a genuine collaboration, it can too often 'export failure' from the West. On the other hand, non-Western epidemiologists are increasingly developing new and innovative approaches to health research that are more appropriate to the global public health issues they are addressing. These include recognition of the importance of context and the importance of diversity and local knowledge, and a problem-based approach to addressing the major public health problems using appropriate technology. These debates formed the background for a plenary session on 'International Epidemiology and International Health' at the recent International Epidemiological Association (IEA) meeting in Montreal, and the papers from this session are presented here. The development of a truly global epidemiology can not only better address the public health problems in non-Western populations, but can shed light on the current limitations of epidemiology in addressing the major public health problems in the West.

  5. Californium-252: a remarkable versatile radioisotope

    International Nuclear Information System (INIS)

    Osborne-Lee, I.W.; Alexander, C.W.

    1995-01-01

    A product of the nuclear age, Californium-252 ( 252 Cf) has found many applications in medicine, scientific research, industry, and nuclear science education. Californium-252 is unique as a neutron source in that it provides a highly concentrated flux and extremely reliable neutron spectrum from a very small assembly. During the past 40 years, 252 Cf has been applied with great success to cancer therapy, neutron radiography of objects ranging from flowers to entire aircraft, startup sources for nuclear reactors, fission activation for quality analysis of all commercial nuclear fuel, and many other beneficial uses, some of which are now ready for further growth. Californium-252 is produced in the High Flux Isotope Reactor (HFIR) and processed in the Radiochemical Engineering Development Center (REDC), both of which are located at the Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. The REDC/HFIR facility is virtually the sole supplier of 252 Cf in the western world and is the major supplier worldwide. Extensive exploitation of this product was made possible through the 252 Cf Market Evaluation Program, sponsored by the United States Department of Energy (DOE) [then the Atomic Energy Commission (AEC) and later the Energy Research and Development Administration (ERDA)]. This program included training series, demonstration centers, seminars, and a liberal loan policy for fabricated sources. The Market Evaluation Program was instituted, in part, to determine if large-quantity production capability was required at the Savannah River Laboratory (SRL). Because of the nature of the product and the means by which it is produced, 252 Cf can be produced only in government-owned facilities. It is evident at this time that the Oak Ridge research facility can meet present and projected near-term requirements. The production, shipment, and sales history of 252 Cf from ORNL is summarized herein

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

  8. Psychology of collective protests: preliminary remarks

    Directory of Open Access Journals (Sweden)

    Cojocaru Natalia

    2016-12-01

    Full Text Available In this article, we present some theoretical syntheses pertaining to the psychology of collective protests, concerning particular factors that determine adherence to and resignation from protest actions, the role of emotions and rituals in the collective protests and new forms of mobilization through online networks. Studies show that mobilization is significantly correlated with the degree of identification with the in-group, identity threat and perception of success, while resignation may be caused by uncertainty about the use of protest or by repressive measures imposed by security forces. One aspect scarcely clarified is what was called the paradox of participation – the persistence of protest despite failures, causing individuals to join again protest actions. Regarding the role of emotions, researchers found that negative emotions against the out-group have an essential role in maintaining the protest action on a longer period. Currently, researchers are particularly interested in the implications of online communication networks (forums, Twitter, Facebook in the organization and unfolding of protest events.

    Full Text Available User perceptions can become vital especially at beach preferences as cleanliness, safety and amenities are some of the apparent factors that will affect. With the awareness of probable adaptation of beach users’ demands into policy recommendations, a case study has been carried out at Black Sea Coast of İstanbul at Şile beaches. Şile has been chosen in this study purposefully as it is a touristic district of İstanbul which has aimed to earn Blue Flag award previously. Secondly, it receives high amount of visitors especially during the peak periods in weekends; as it has a very close location to the city, people are choosing here most of the time just for the day. In this research with factors about human use of beach and impacts like cleanliness and sufficiency of amenities (showers, toilets, changing cubicles, parks etc. and the number of lifeguards are studied. Regarding the findings, the researchers consequently highlight recommendations for Şile beach management which could enhance the visitor experience.

    Science.gov (United States)

    Strayer, Michael

    2007-09-01

    SciDAC work. I am pleased that the President's FY08 budget restores the funding for SciDAC. Quoting from Advanced Scientific Computing Research description in the House Energy and Water Development Appropriations Bill for FY08, "Perhaps no other area of research at the Department is so critical to sustaining U.S. leadership in science and technology, revolutionizing the way science is done and improving research productivity." As a society we need to revolutionize our approaches to energy, environmental and global security challenges. As we go forward along the road to the X-scale generation, the use of computation will continue to be a critical tool along with theory and experiment in understanding the behavior of the fundamental components of nature as well as for fundamental discovery and exploration of the behavior of complex systems. The foundation to overcome these societal challenges will build from the experiences and knowledge gained as you, members of our SciDAC research teams, work together to attack problems at the tera- and peta- scale. If SciDAC is viewed as an experiment for revolutionizing scientific methodology, then a strategic goal of ASCR program must be to broaden the intellectual base prepared to address the challenges of the new X-scale generation of computing. We must focus our computational science experiences gained over the past five years on the opportunities introduced with extreme scale computing. Our facilities are on a path to provide the resources needed to undertake the first part of our journey. Using the newly upgraded 119 teraflop Cray XT system at the Leadership Computing Facility, SciDAC research teams have in three days performed a 100-year study of the time evolution of the atmospheric CO2 concentration originating from the land surface. The simulation of the El Nino/Southern Oscillation which was part of this study has been characterized as `the most impressive new result in ten years' gained new insight into the behavior of

    This paper reviews the status of research on radiation- pasteurization of fish and shell fish in the United States and describes plans for commercialization of the process. The authors discuss: (a) laboratory studies at universities and governmental research institutions on quality and microbiological aspects of irradiated sea food; (b) developmental investigations on irradiating fish ashore and at sea; and (c) United States clearance of radiation pasteurized sea food and use of the process in the fishing industry. Quality studies indicate that irradiation with cobalt-60 at levels of 150 000 at 450 000 rad can at least double the refrigerated shelf life of 16 species of fish and shell fish, which include the major species marketed as fresh or frozen in the United States. Storage temperature, quality of raw material, and dose level significantly affect product quality and shelf life; packaging is of less significance. Synergistic systems, using bactericidal salts or heat, in conjunction with radiation, effectively destroy bacteria and offer promise in reducing radiation levels and extending product shelf life over that when radiation is used alone. Irradiation at very low levels significantly changes the microbial flora of fish fillets, but interestingly enough this change is no greater than that which occurs when storing the product in an anaerobic environment. In discussing microbiological changes in irradiated and non- irradiated fish, the authors point out that treated fish fillets are as safe and wholesome as the non-treated fish. Work on safety aspects of irradiated fish fillets is discussed in detail. Developmental studies received emphasis with construction and operation of a 250 000 Ci cobalt-60 fish-processing facility at Gloucester, Mass. Tests on packaging and shipping irradiated products under simulated commercial conditions show that pasteurized fish can be handled in the same manner as fresh fish, with a resultant doubling of shelf life for the former

  16. Generation IV international forum 2002 - remarks

    International Nuclear Information System (INIS)

    Abraham, S.

    2002-01-01

    Analyses and forecasts underscore the important role of nuclear power in energy supply in the 21st century. Important aspects in this respect are the conservation of fossil resources, the protection of the world's climate, and the continuity of supply. Present 1st and 2nd generation nuclear power plants ensure an economical and technically mature electricity supply. Advanced systems offering, e.g., higher efficiency of fuel utilization, simplified systems technology, and advanced safety characteristics, can make available additional benefits in using nuclear power. Upon an initiative of the U.S. Department of Energy (DOE), ten countries combine their efforts in developing such reactor concepts in the Generation IV International Forum (GIF). Argentina, Brazil, Canada, France, Japan, South Africa, South Korea, Switzerland, the United Kingdom, and the United States pursue the common objective in GIF to identify suitable nuclear power systems and promote their development up to the envisaged readiness for construction in 2030. Besides technical and economic questions of nuclear power generation, also other aspects must be considered with a view to the future use of nuclear power. The particularly relevant issues, such as the management of radioactive waste, the intensification of research and development, and international cooperation, have been taken up by the Bush administration at an early point in time and have been, or will be, incorporated in practical solutions, as in the case of the Yucca Mountain repository project.

    This is the twelfth international Safeguards Symposium, hosted by the IAEA. And once again it is being held in cooperation with the Institute of Nuclear Materials Management and the European Safeguards Research and Development Association. Our theme is Strategy, Implementation and People. Linking the three core processes of any business - the strategy, its implementation and the people doing the work - determines the success or failure of every organization. And the strength of the link between these three processes determines the degree to which a business is able to deliver what it wants to achieve. The IAEA is no exception. To achieve our vision, meet our obligations and fulfill the expectation of our Member States requires the careful and successful linking of strategy, implementation and people, and that is what we will all be focusing on during our deliberations this week. The primary objective of this symposium is to foster dialogue and information exchange between the IAEA and experts from Member States, the nuclear industry and the broader nuclear non-proliferation community

  1. OPENING REMARKS: Scientific Discovery through Advanced Computing

    Good morning. Welcome to SciDAC 2006 and Denver. I share greetings from the new Undersecretary for Energy, Ray Orbach. Five years ago SciDAC was launched as an experiment in computational science. The goal was to form partnerships among science applications, computer scientists, and applied mathematicians to take advantage of the potential of emerging terascale computers. This experiment has been a resounding success. SciDAC has emerged as a powerful concept for addressing some of the biggest challenges facing our world. As significant as these successes were, I believe there is also significance in the teams that achieved them. In addition to their scientific aims these teams have advanced the overall field of computational science and set the stage for even larger accomplishments as we look ahead to SciDAC-2. I am sure that many of you are expecting to hear about the results of our current solicitation for SciDAC-2. I’m afraid we are not quite ready to make that announcement. Decisions are still being made and we will announce the results later this summer. Nearly 250 unique proposals were received and evaluated, involving literally thousands of researchers, postdocs, and students. These collectively requested more than five times our expected budget. This response is a testament to the success of SciDAC in the community. In SciDAC-2 our budget has been increased to about 70 million for FY 2007 and our partnerships have expanded to include the Environment and National Security missions of the Department. The National Science Foundation has also joined as a partner. These new partnerships are expected to expand the application space of SciDAC, and broaden the impact and visibility of the program. We have, with our recent solicitation, expanded to turbulence, computational biology, and groundwater reactive modeling and simulation. We are currently talking with the Department’s applied energy programs about risk assessment, optimization of complex systems - such

    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.

    High energy physics is a basic research domain with a well established European and international cooperation. Cooperation can be of different type depending on the size of the facilities involved (accelerators), on their financing, and on the type of experiments that use these facilities. The CERN, the European center for nuclear research, created in October 1954, is the best example of such a cooperation. This article examines first the juridical and scientifical structure of the CERN and the mode of organization of big experiments. Then, it presents the role of international committees in the establishment of a common scientific policy in Europe and in the rest of the world. Finally, the possible future evolution of the CERN towards a worldwide project is evoked. (J.S.)

  8. Preface: Introductory Remarks: Linear Scaling Methods

    It has been just over twenty years since the publication of the seminal paper on molecular dynamics with ab initio methods by Car and Parrinello [1], and the contribution of density functional theory (DFT) and the related techniques to physics, chemistry, materials science, earth science and biochemistry has been huge. Nevertheless, significant improvements are still being made to the performance of these standard techniques; recent work suggests that speed improvements of one or even two orders of magnitude are possible [2]. One of the areas where major progress has long been expected is in O(N), or linear scaling, DFT, in which the computer effort is proportional to the number of atoms. Linear scaling DFT methods have been in development for over ten years [3] but we are now in an exciting period where more and more research groups are working on these methods. Naturally there is a strong and continuing effort to improve the efficiency of the methods and to make them more robust. But there is also a growing ambition to apply them to challenging real-life problems. This special issue contains papers submitted following the CECAM Workshop 'Linear-scaling ab initio calculations: applications and future directions', held in Lyon from 3-6 September 2007. A noteworthy feature of the workshop is that it included a significant number of presentations involving real applications of O(N) methods, as well as work to extend O(N) methods into areas of greater accuracy (correlated wavefunction methods, quantum Monte Carlo, TDDFT) and large scale computer architectures. As well as explicitly linear scaling methods, the conference included presentations on techniques designed to accelerate and improve the efficiency of standard (that is non-linear-scaling) methods; this highlights the important question of crossover—that is, at what size of system does it become more efficient to use a linear-scaling method? As well as fundamental algorithmic questions, this brings up

Le GERP regroupe actuellement des membres scientifiques multidisciplinaires Malgaches et étrangers dont la majorité d’entre eux est constituée par des primatologues. Les principales actions du GERP se focalisent sur les travaux de recherche sur les Primates Prosimiens de Madagascar, l’établissement de leur plan de conservation, la découverte de nouvelles espèces de lémuriens, la translocation et le transfert des lémuriens vivant dans des milieux défrichés ou précaires, le suivi et l’abondance des lémuriens ainsi que la révision de leurs aires de distribution. Les résultats des recherches effectuées sur la conservation ont permis de publier des articles dans des revues de renommée nationale et internationale sur la Primatologie. En outre, le renforcement de capacité et l’éducation de la communauté de base, des systèmes éducatifs primaires et supérieurs sur la conservation des lémuriens et l’appui aux activités de développement durable de la population locale s’avèrent nécessaires pour que la conservation des lémuriens soit pérenne.The Madagascar Primate Research Group (GERP - Groupe d’Etude et de Recherche sur les Primates de Madagascar is a conservation-focused association created in 1994 by the initiative of researcher lecturers and students from the Department of Paleontology and Biological Anthropology and the Department of Animal Biology of the University of Antananarivo.

Les auteurs analysent les enjeux méthodologiques qui se sont posés sur ce terrain particulier relevant de la sociologie de la déviance. Ceux-ci sont liés, notamment, à la participation de chaque groupe d’acteurs aux différentes étapes de la recherche, à la présence d’intérêts différents portés par chacun d’entre eux, et à la conciliation entre les principes habituellement de rigueur dans l’enquête sociologique et les principes de la recherche-action.Research-Action has two main objectives: to allow different players to cooperate, and to transform social reality. This methodology has both the strengths and the weaknesses of strictly cognitive research. In this article, the authors discuss a research-action project which brought together sociologists, social workers and squatters from the Ile-de-France region (Paris and surrounding region. Methodological issues that arise specifically in the context of deviance are addressed, notably the participation of the different players at different stages of the research project, their different areas of interest, as well as the reconciliation between more conventional sociological research and the principles of research-action.

    Aujourd'hui, les façons de produire, d'organiser, d'évaluer et d'utiliser les savoirs sont en profond débat. De plus en plus, l'Etat, la société civile et l'économie tentent d'influencer les activités des universités et des laboratoires de recherche. Ces développements mettent à l'épreuve tout à la fois les fondements des systèmes d'enseignement supérieur et de recherche, l'autonomie des institutions scientifiques, la définition des frontières des savoirs et l'acceptation des sciences. Dans des contextes suisses et européens, cet ouvrage s'intéresse aux manières dont les sciences et les technologies sont fabriquées, en analysant leurs institutions et les pratiques. A partir d'une approche relationnelle, les sciences et les technologies sont conçues comme des phénomènes profondément sociaux, culturels et politiques.

    The functions of a nuclear materials management scheme are reviewed in relation to the activities of research establishments. Since these activities are normally non-repetitive, there is little opportunity to establish statistical quality and quantity control. The risks of an error in the material accounts must therefore be established from relatively few analytical measurements and the implications of this are discussed. Similar arguments are applied to illustrate the difficulties of quality control on suppliers when a large variety of materials are being purchased in small quantities. (author) [French] Les auteurs examinent le role d'un systeme de gestion des matieres nucleaires applique aux activites des centres de recherche. Comme ces activites ne sont normalement pas appelees a se repeter, il n'est guere possible d'organiser un controle statistique quantitatif et qualitatif. Il faut donc determiner les possibilites d'erreurs dans la comptabilite matieres en s'appuyant sur un nombre relativement restreint de mesures analytiques et les auteurs examinent les conclusions a tirer de cette situation. Ils recourent a une argumentation analogue pour illustrer les difficultes inherentes au controle de la qualite des matieres livrees par les fournisseurs lorsqu'il doit porter sur une grande diversite de matieres en petites quantites.

Franç. du Pétrole, vol. 45, n°6, novembre-décembre 1990 concernant l'application des techniques de diffusion de la lumière, des rayons X et des neutrons à l'étude des systèmes colloïdaux et plus précisément à la présentation théorique des trois méthodes. L'objet de cette deuxième partie est la présentation non exhaustive de quelques domaines d'applications. Nous nous attacherons tout particulièrement à présenter les potentialités des méthodes pour la caractérisation de systèmes colloïdaux ou divisés rencontrés dans de nombreuses branches d'activité de l'industrie pétrolière. Nous aborderons dans une première partie les solutions polymériques et colloïdales. En particulier nous nous attarderons sur l'importance des techniques de diffusion pour la caractérisation des polymères en solution et des solutions micellaires. Nous verrons également quelles informations la diffusion centrale peut apporter sur la macrostructure des polymères cristallisés ou amorphes à l'état solide. De nombreux systèmes présentent une structure de type fractal ; après présentation de quelques exemples, nous montrerons que les méthodes de diffusion peuvent apporter certaines informations sur ces matériaux, notamment la dimension fractale. This article is the second one (the first one was published in Revue de l'Institut Français du Pétrole No. 6, NovemberDecember 1990 concerning the application of techniques of light scattering, X rays and neutrons to the analysis of colloidal systems and more specifically to the theoretical description of the three methods. The aim of this second part is to make a nonexhaustive description of several fields of applications. A special effort is made to describe the potential of these methods for characterizing colloidal or divided systems encountered in a great many activities involving the petroleum industry.

    Full Text Available The European Directive 2010/63/EU on the protection of animals used for scientific purposes requires that a feasibility study must be conducted by the European Commission to determine if all sourcing of non-human primates from parents bred in captivity (F2 or from self-sustaining colonies can be achieved. This study should also include an assessment of animal health and welfare. Prior to the initiation of the European Commission’s study, it was considered by EFPIA and FELASA that the criteria to be used in the feasibility, health and welfare assessment should be established by experts to help expedite such a study. This paper identifies those criteria which may be useful in making policy decisions on the confirmation or reconsideration of the timetable for implementation of the F2 requirement. A key requirement before a number of criteria can be assessed is the generation of base-line data relating to the supply and future demand of non-human primates and the health and welfare status of current breeding colonies supplying the European market. Three groups of criteria have been indentified, namely feasibility, science and research and welfare. Within each group, a number of parameters are defined and their rationale for inclusion, together with suggested information points, is discussed.La directive européenne 2010/63/EU sur la protection des animaux utilisés à des fins scientifiques exige qu'une étude de faisabilité soit conduite par la Commission européenne afin de déterminer si l’approvisionnement en primates non-humains à partir de géniteurs élevés en captivité (F2 ou de colonies d'élevage autosuffisantes, peut être possible. Cette étude devra également inclure une évaluation de la santé des animaux et de leur bien-être. Avant le début de cette étude par la Commission européenne, l'EFPIA et FELASA ont estimé que les critères à utiliser pour les évaluations de la faisabilité, de la santé des animaux et du bien

    Research in geology may be divided into three categories according to the degree of containment required for the waste in order to assure conformance with generally accepted standards of health and safety. I. Maximum containment environments are intended to retain for centuries or for millenia essentially all waste materials stored in them. Two general types are under investigation, salt deposits and deep permeable formations. In both cases various laboratory experiments are being performed to study the interaction between waste solutions and appropriate earth materials, and, in the case of salt, a field experiment is in progress utilizing simulated (non-radioactive) high-activity waste. II. Intermediate containment environments are intended to slow down significantly the mobility of radioactive wastes to provide sufficient time for radioactive decay before the wastes come into contact with man or his food chain. Examples of intermediate containment are shallow burial of packaged waste, and discharge of bulk liquid waste into seepage pits. Research is in progress to study the combined effect of transport of radionuclides by ground water and retention of radionuclides by sorption on earth materials. III. Environments of no containment are those in which radionuclides are immediately brought into contact with man or with any of the biota of his food chain. Research is under way both to determine the capacity of individual environments to receive such waste within health and safety limits, and to improve techniques for doing so. Current research includes (a) classification of terrains as related to waste disposal problems, (b) study of diffusion characteristics of streams, (c) the effect of organic and inorganic stream solids on radioactivity concentration, and (d) the effect of suspended sediment and river-bed material on the transportation of radionuclides.

    A review of the waste-disposal research and development carried out in the United States of America is given. The major research effort concerns the conversion of high-level liquid wastes into solids. At Hanford and Oak Ridge low-level wastes are disposed to the ground in pits, cribs and lagoons. Geochemical studies related to waste disposal are conducted at Hanford, Oak Ridge and the University of North Carolina. Experiments with soil columns ate described ; these are more effective for the decontamination of waste streams than either cribs or pits. The most suitable exchange materials for the soil columns are found to be vermiculite supported by rock phosphate and the latter supported by graded gravel. The progress of research work on the possibility of injecting radioactive liquid wastes into porous formations through deep wells and disposing of radioactive wastes in impermeable formations by hydraulic fracturing is outlined. (author) [French] L'auteur passe en revue les recherches effectuees aux Etats-Unis en matiere d'elimination des dechets radioactifs et les progres accomplis dans ce domaine. En matiere de recherche, on s'attache principalement a la conversion en solides des dechets liquides de haute activite. A Hanford et a Oak Ridge, les dechets de faible activite sont elimines par decharge terrestre dans des coffres, puits et depots lagunaires. Des etudes de geochimie se rapportant a l'elimination des dechets sont en cours a Hanford, a Oak Ridge et l'Universite de Caroline du Nord. Le memoire decrit les experiences faites avec des colonnes ; pour decontaminer les dechets liquides, ces dernieres sont plus efficaces que les coffres ou les puits. Les substances echangeuses d'ions les plus appropriees pour les colonnes sont vermiculite-phosphate naturel-gravier trie.

    Full Text Available Prenant les déchets électriques et électroniques comme terrain d’observation, cette recherche étudie les fondements du commerce illégal de déchets dangereux des pays développés vers les PED. En effet, malgré la multiplication des législations, le problème des déchets dans les pays développés, loin d’être traité en amont, l’est en grande partie en aval par leur délocalisation dans les PED. Les deux lectures proposées, économique et institutionnelle, permettent de montrer comment les contraintes de coût de gestion des déchets dans les pays développés conjuguées à l’imperfection et à la non-application des législations conduisent à des comportements socialement irresponsables. À partir de là, l’implication des parties prenantes est suggérée comme solution pour éliminer ce type de comportements.Based on the analysis of the waste electrical and electronic equipments (WEEE, the research investigates the motivations for the illegal cross-border trade in hazardous wastes from developed countries to developing countries. Although many developed countries have implemented waste shipment regulations, they are passing the risks and costs of E-waste to developing countries. Indeed, E-waste is often sent for recycling and refurbishing in developing countries. The two-side proposed approach (i.e. economical and institutional suggests that both the cost for firms to comply with increasing regulations and the imperfect implementation of regulatory restrictions lead to socially irresponsible behaviours. An increasing and better involvement of stakeholders may be put forward as a solution.

    Écrire l'histoire de l'Univers, tel est l'objectif commun des physiciens des particules et des astrophysiciens. Pour y parvenir, deux approches s'épaulent : la voie de l'infiniment petit, que l'on emprunte via de gigantesques accélérateurs de particules, et celle de l'infiniment grand, dont le laboratoire est l'Univers. Un Univers qui est bien loin d'avoir livré tous ses secrets. On connaît à peine 4,8 % de la matière qui le constitue, le reste étant composé de matière noire (25,8 %) et d'énergie noire (69,4 %), toutes deux de nature inconnue. Et si la récente découverte du boson de Higgs valide le Modèle standard de la physique des particules, celui-ci est toujours incomplet et doit être étendu à ou dépassé.

    Mnif, Thameur

    Le travail presente ici est un bilan du travaux de recherche effectues sur l'injectabilite des coulis de ciment dans lu milieux fissures. Un certain nombre de coulis a base de ciment Portland et microfin ont ete selectionnes afin de caracteriser leur capacite a penetrer des milieux fissures. Une partie des essais a ete menee en laboratoire. L'etude rheologique des differents melanges a permis de tester l'influence de l'ajout de superplastifiant et/ou de fumee de silice sur la distribution granulometrique des coulis et par consequent sur leur capacite a injecter des colonnes de sable simulant un milieu fissure donne. La classe granulometrique d'un coulis, sa stabilite et sa fluidite sont apparus comme les trois facteurs principaux pour la reussite d'une injection. Un facteur de finesse a ete defini au cours de cette etude: base sur la classe granulometrique du ciment et sa stabilite, il peut entrer dans la formulation theorique du debit d'injection avant application sur chantier. La deuxieme et derniere partie de l'etude presente les resultats de deux projets de recherche sur l'injection realises sur chantier. L'injection de dalles de beton fissurees a permis le suivi de l'evolution des pressions avec la distance au point d'injection. L'injection de murs de maconnerie a caractere historique a montre l'importance de la definition de criteres de performance des coulis a utiliser pour traiter un milieu donne et pour un objectif donne. Plusieurs melanges peuvent ainsi etre predefinis et mis a disposition sur le chantier. La complementarite des ciments traditionnels et des ciments microfins devient alors un atout important. Le choix d'utilisation de ces melanges est fonction du terrain rencontre. En conclusion, cette recherche etablit une methodologie pour la selection des coulis a base de ciment et des pressions d'injection en fonction de l'ouverture des fissures ou joints de construction.

    Full Text Available Un inventaire exact des gîtes de houille était lié à la réorganisation des rapports de propriété dans la région de la Ruhr (Fondation de la Ruhrkohle AG. Du fait que dans les domaines de gîtes de houille en exploitation les réserves de houille ne suffiront pas à assurer à long terme un rendement d'extraction suffisant, on commença une vaste exploration dans des parties de quartier encore inconnues. Il fut ainsi possible d'élargir considérablement les connaissances sur la situation géologique des gîtes de houille grâce à des études par réflexion sismique, des forages profonds et des enregistrements de forages géophysiques. An accurate inventory of the coal beds was dependent upon the reorganization of property reports in the Ruhr region (Ruhrkohle Fondation AG. Because the working coal fields do not contain sufficient coal reserves to guarantee satisfactory productivity rates on a long-term basis, extensive exploration in previously unexplored parts of the area was undertaken. Thus, it became possible to extend considerably our knowledge of the geological structure of the coal beds through refraction shooting, deep drilling, and the well logging.

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

  15. Mykotische Infektionen des Penis

    Directory of Open Access Journals (Sweden)

    1999-01-01

    Full Text Available Die häufigste mykotische Infektion des Penis stellt die Balanitis/Balonoposthitis durch Candida albicans dar. Sie weist eine steigende Inzidenz auf und scheint vornehmlich durch Genitalverkehr übertragen zu werden. Penile Infektionen durch Dermatophyten sind sehr selten, obwohl die Tinea inguinalis zu den häufigeren Erkrankungen zählt. Eine Mitbeteiligung des Penis im Rahmen von Systemmykosen kennzeichnet zumeist ein schwer verlaufende Erkrankung. Ursächlich kann beim immunoinkompetenten Patienten nahezu jeder Erreger in Frage kommen. Biopsie sowie Gewebekultur aus den meist ulzerativen Veränderungen können die Diagnose sichern. Die meisten superfiziellen Infektionen sprechen zufriedenstellend auf eine topische antimykotische Behandlung an, insbesondere wenn Provokationsfaktoren und die Möglichkeit der sexuellen Transmission berücksichtigt werden. Ausgedehnte Infektionen durch Dermatophyten, Hefen und natürlich systemische Infektionen erfordern eine systemische antimykotische Therapie.

    Die Organtransplantation stellt eine verbreitete Therapie dar, um bei krankheitsoder unfallbedingter Schädigung eines Organs die Gesamtheit seiner Funktionen wieder herzustellen, indem es durch ein Spenderorgan ersetzt wird. Organtransplantationen werden für die Leber, die Niere, die Lunge, das Herz oder bei schweren grossflächigen Verbrennungen der Haut vorgenommen. Der grosse apparative, personelle und logistische Aufwand und die Risiken der Transplantationschirurgie (Abstossungsreaktionen) sowie die mangelnde Verfügbarkeit von immunologisch kompatiblen Spenderorganen führen jedoch dazu, dass der Bedarf an Organtransplantaten nur zu einem sehr geringen Teil gedeckt werden kann. Sind Spenderorgane nicht verfügbar, können in einzelnen Fällen lebenswichtige Teilfunktionen, wie beispielsweise die Filtrationsfunktion der Niere durch die Blutreinigung mittels Dialyse ersetzt oder, bei mangelnder Funktion der Bauchspeicheldrüse (Diabetes), durch die Verabreichung von Insulin ein normaler Zustand des Gesamtorganismus auch über Jahre hinweg erhalten werden. Bei der notwendigen lebenslangen Anwendung apparativer oder medikamentöser Therapie können für den Patienten jedoch häufig schwerwiegende, möglicherweise lebensverkürzende Nebenwirkungen entstehen. Daher werden in der Forschung Alternativen gesucht, um die Funktionen des ausgefallenen Organs durch die Implantation von Zellen oder in vitro gezüchteten Geweben möglichst umfassend wieder herzustellen. Dies erfordert biologisch aktive Implantate, welche die für den Stoffwechsel des Organs wichtigen Zellen enthalten und einen organtypischen Stoffwechsel entfalten.

Cette étude confronte l’analyse des phénomènes visuels engendrés par le jaunissement du vernis et son retrait, à des entretiens réalisés à dessein. Le retrait d’un vernis jauni change considérablement l’image. L’heure, le climat, la saison et l’activité même des personnages s’en trouvent ainsi modifié. La patine peut être perçue, soit comme un obstacle à l’exploration, soit pour ceux qui l’apprécient, comme le medium d’une relation plus intime entre l’œuvre et l’observateur.The purpose of this article is to understand the semiotic impact of the cleaning of a painting and the cognitive effects induced on the observer. This study analyses conjointly the visual phenomenon generated by yellowing varnish and its removal and controlled interviews of observers.The removal of yellowing varnish modifies considerably the perception of the picture. Daytime, climate, season and characters activities are modified. The patina may be perceived either as an obstacle to the painting exploration, or, for those who appreciate it, as a medium for a closer relationship between the painting and the observer.

    For studying these reactions, the detection of the final particles emitted in coincidence in the directions {theta}{sub 1} and {theta}{sub 2}, together with the bi-parametric analysis of the corresponding pulses are used. This method enables us to obtain the orthogonal Dalitz diagrams (E{sub 1}, E{sub 2}). An examination of the spectra obtained shows that the sequential mechanism appears to predominate. The contribution of the purely statistical process is less than 15 per cent of the total spectrum. In the case of {sup 10}B (d, 3 {alpha}), for E{sub d} = 1.5 MeV, 2,66 MeV and 3 MeV, the width of the peak of the first particles emitted, with respect to {sup 8}Be excitations close to 11 MeV, is found to be equal to 2.6 {+-} 0.6 MeV, much less than the width of the 2. excited state observed by {alpha} - {alpha} scattering. The coincidence spectra and the free spectra give an excitation energy of E{sub x} = 2.68 {+-} 0.07 MeV for the first excited state of {sup 8}Be.

    Signogneau, A

    1995-11-22

    The goal of this thesis is to analyse how the academic domain of a research entity can be defined by a panel of scientific journals. The aim of this work is to contribute to the creation of information tools as a help in research management. The first part gives an analysis of the scientific journals as markers of the scientific development: the production and diffusion of scientific journals and their ``scientometrical`` analysis (references, citation reports, citation indexes etc..). In the second part, a research unit is analyzed according to its related scientific journals and to its research domain. The SPAM (Photons, Atoms and Molecules Service) of the CEA was chosen for this task (main journals and co-publications network, specialization, main topics, collaborations and competition). The OST (Observatory of Sciences and Techniques) has in charge the production of scientific and technical indicators for research operators. The third part evaluates the methods used by the OST (analyses of reviews and journals) to provide a documentary corpus, taking the topic of the environment as an example. Finally the relevance of the information products obtained is evaluated. (J.S.).

    The resource-efficient handling of raw materials also includes the knowledge of already processed raw materials in the meanings of the recycling management. The research project 'Hybride Lithiumgewinnung', which is funded by the Federal Ministry of Education and Research (BMBF) and GC Potential (German: WK Potential), will investigate the raw material Lithium in particular. The study of the recovery of secondary raw materials focuses on the device batteries. The findings of the market study on device batteries will be presented with the priority for Lithium device batteries. A status analysis of resent battery systems focusing Lithium batteries and a stockpile analysis in a German sorting facility for used Lithium batteries were conducted. The aim of the investigation is the varying kinds of chemical composition of Lithium batteries and to determine the age distribution of the used Lithium batteries. (orig.)

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

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

    Numerous physical, chemical and biological processes influence the distribution of radioactive materials and their return to man. These include vertical and horizontal advection, turbulent diffusion, precipitation and sedimentation, uptake concentration, and transport by organisms, and transfer to man through his food from the sea. Research is urgently needed on the flushing characteristics of typical harbours, estuaries and open coastal waters, on diffusion and sedimentation processes in inshore waters, and on the passage of radioactive elements through the food web in this portion of the sea. Research is needed to delineate present and potential fishing areas, and non-fishing areas, by basic studies of biological productivity and other means. Studies are also required to determine rates of transfer of radioactive materials between areas by horizontal advection and turbulent diffusion, rates of dilution by diffusion, sedimentation, and vertical transport, and rates of uptake and transfer by the biota. Research is required on efficient means of monitoring waste disposal areas. The ability of certain organisms selectively to concentrate particular elements offers a possible economical basis of monitoring radioactive wastes in the sea at very low concentrations. Specific research proposals have been recently developed by several groups of oceanographers in the United States. These are summarized, together with cost estimates.

    An important research programme on heavy water reactor physics has been carried out in France for quite a few years. The decision to build the EL 4 prototype and so to choose the heavy water gas cooled type has renewed the interest in this programme and at the same time given to it a more specific orientation A summary of the results gained in this field is presented in this paper. In the first part are described the experimental investigations, most of them were carried out in the criticality facility AQUILON II. The experiments are grouped in four parts - Systematic studies of lattices Buckling measurements. - Specific studies of gas-cooled lattices. - Fine structure, spectral indices measurements etc... - Measurements on lattices or samples containing Uranium of various enrichment or Plutonium. The second part is devoted to a summary of the theoretical studies. The whole results have allowed an improvement of the calculation methods, have led to a better understanding of the neutron balance in lattices, and have permitted the establishment of a set of formula to predict not only the clean fuel conditions but also the evolution of the nuclear properties with irradiation. Some specific studies on power reactor are quoted. (authors) [French] Un important programme d'etudes sur la physique des reacteurs a eau lourde est mene en France depuis assez longtemps.

    Galle, P.

    Proposed in 1960 by R. Castaing and G. Slodzian, secondary ion emission microanalysis is a microanalytical method which is now largely used for the study of inert material. The instrument called the analytical ion microscope can also be used for the study of biological spécimens ; images representing the distribution of a given stable or radioactive isotope in a tissue section are obtained with a resolution of 0.5 μm. Among the characteristics of this method, two are of particular interest in biological research : its capacity for isotopic analysis and its very high sensitivity which makes possible for the first time a chemical analysis of element at a very low or even at a trace concentration in a microvolume. Proposé en 1960 par R. Castaing et G. Slodzian, la microanalyse par émission ionique secondaire est une méthode qui permet, entre autre, d'obtenir des images représentant la distribution des isotopes présents à la surface d'un échantillon solide avec une résolution de 0,5 μm. D'intérêt très général, cette méthode a été d'abord largement utilisée pour l'étude des matériaux inertes. Elle offre en outre des possibilités entièrement nouvelles dans le domaine de la recherche biomédicale. L'instrument réalisé, le microscope ionique analytique présente deux caractéristiques particulièrement intéressantes pour la biologie : la possibilité d'analyse isotopique, et l'extrême sensibilité permettant de détecter et de localiser dans une coupe histologique des éléments à des concentrations très faibles voire à l'état de trace.

    This report deals with the components and use of resistivity probes in bubble flow. With a single probe, we have studied the longitudinal and radial structure of the flow. The very complicated evolution of the radial structure is shown by the measurement of the mean bubble flux at several points in the tube. A double probe associated with a device the principle of which is given in this report, permits the measure of the local velocity of bubbles. Unlike the mean bubble flux profile, the change in the velocity profile along the tube is not significant. We have achieved the synthesis of these two pieces of information, mean local bubble flux and local velocity, by computing the mean weighed velocity in the tube.

    Les compactifications diverses de variétés de modules sont un thème important et récurrent des mathématiques modernes, et elles connaissent un grand nombre d'applications. Ce livre traite le cas de cellules de Schubert minces, qui sont de sous-variétés naturelles de grassmanniennes. L'auteur a été amené à traiter ces questions par un cas particulier lié à ses travaux sur le programme de Langlands. Dans cette monographie, il en développe une théorie plus systématique, présentant le fortes similarités avec celle des modules du courbes stables. The various compactifications of moduli spaces are an important recurrent theme of modern mathematics, and they have a large number of applications. This book treats the case of thin Schubert varieties, which are natural subvarieties of Grassmannians.

  12. Remarks on the 'Grenelle Environnement' portfolio of measures

    International Nuclear Information System (INIS)

    2009-01-01

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

  13. Remarks on Hamiltonian structures in G2-geometry

    International Nuclear Information System (INIS)

    Cho, Hyunjoo; Salur, Sema; Todd, A. J.

    2013-01-01

    In this article, we treat G 2 -geometry as a special case of multisymplectic geometry and make a number of remarks regarding Hamiltonian multivector fields and Hamiltonian differential forms on manifolds with an integrable G 2 -structure; in particular, we discuss existence and make a number of identifications of the spaces of Hamiltonian structures associated to the two multisymplectic structures associated to an integrable G 2 -structure. Along the way, we prove some results in multisymplectic geometry that are generalizations of results from symplectic geometry

  14. Unbound color, prefaced by remarks on baryon spectroscopy

    International Nuclear Information System (INIS)

    Greenberg, O.W.

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

  15. Remarkable rates of lightning strike mortality in Malawi.

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

    2012-01-01

    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.

    1977-01-01

    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

    Piccolo, Lidia Del; Finset, Arnstein; Mellblom, Anneli V; Figueiredo-Braga, Margarida; Korsvold, Live; Zhou, Yuefang; Zimmermann, Christa; Humphris, Gerald

    2017-12-01

    To discuss the theoretical and empirical framework of VR-CoDES and potential future direction in research based on the coding system. The paper is based on selective review of papers relevant to the construction and application of VR-CoDES. VR-CoDES system is rooted in patient-centered and biopsychosocial model of healthcare consultations and on a functional approach to emotion theory. According to the VR-CoDES, emotional interaction is studied in terms of sequences consisting of an eliciting event, an emotional expression by the patient and the immediate response by the clinician. The rationale for the emphasis on sequences, on detailed classification of cues and concerns, and on the choices of explicit vs. non-explicit responses and providing vs. reducing room for further disclosure, as basic categories of the clinician responses, is described. Results from research on VR-CoDES may help raise awareness of emotional sequences. Future directions in applying VR-CoDES in research may include studies on predicting patient and clinician behavior within the consultation, qualitative analyses of longer sequences including several VR-CoDES triads, and studies of effects of emotional communication on health outcomes. VR-CoDES may be applied to develop interventions to promote good handling of patients' emotions in healthcare encounters. Copyright © 2017 Elsevier B.V. All rights reserved.

    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.

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

    Directory of Open Access Journals (Sweden)

    Jônadas Techio

    2012-12-01

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

    2010-01-01

    Document available in extended abstract form only. ANDRA is directly responsible for all scientific data acquired in real time and wire-line at the Meuse Haute- Marne underground research laboratory. To fulfil the needs for the acquisition, storage and display of realtime data, Andra decided to develop and install a system called SAGD (Systeme d'Acquisition et de Gestion des Donnees). With this view, a system was designed to: - Determine the acquisition tools and methods so that technical failures would not result in the loss of data or the acquisition of erroneous data, - Store (conservation) in the long-term all data in a single place in a single form, - Allow the diffusion and free access of data to the large community of ANDRA researchers, partners and service contractors in a single fluid way whatever the source of the data. - Help external communication through a user friendly and easy to understand presentation of the recorded data. S.A.G.D fulfils these objectives by: - Making available in real time, and through a single system, all experimental data under acquisition at the MHM Center and Mont Terri laboratory, - Displaying the recorded data on temporal windows and specific time step, - Allowing remote control of the experimentations, - Ensuring the traceability of all recorded information, - Ensuring data storage in a data base. S.A.G.D has been deployed in the first experimental drift at -445 m in November 2004. It was subsequently extended to the underground Mont Terri laboratory in Switzerland in 2005 and to the entire surface logging network of the Meuse / Haute-Marne Center in 2008. The SAGD computer network is an autonomous network consisting of optical fiber links which transmits experimentation data to the servers and computers in the control room, whether they originate from the bottom of a borehole or surface level. A high speed link between Mont Terri and Bure allows remote control of all the experimentations and the centralization of all

Les réactions de pyrolyse, d'oxydation et de combustion mises en jeu par ces techniques sont discutées, en particulier la cinétique des principaux mécanismes réactionnels, l'importance du dépôt de coke et l'exothermicité des réactions d'oxydation et de combustion. Les résultats d'essais de déplacement unidirectionnel du front de combustion dans des cellules de laboratoire sont présentés et discutés. Enfin on indique les conditions pratiques d'application des méthodes de combustion in situ sur champ. Possible variations of in situ combustion technique ore as follows : forward or reverse combustion depending on the relative directions of the air flow and the combustion front, dry combustion if air is the only fluid injected into the oil-bearing formation, or fixe/woter flooding if water is injected along with air. The chemical reactions of pyrolysis, oxidation and combustion involved in these processes are described. The kinetics of these reactions is discussed as well as fuel availability in forward combustion and the exothermicity of the oxidation and combustion reactions. The results obtained in the laboratory when a combustion front propagates in unidirectional adiabatic tells are described and discussed. This type of experimentation provides extensive information on the characteristics of the processes. Screening criteria for the practical application of in situ combustion techniques are presented.

    Benoit, Louis

    En 1984 Belavin, Polyakov et Zamolodchikov revolutionnent la theorie des champs en explicitant une nouvelle gamme de theories, les theories quantiques des champs bidimensionnelles invariantes sous les transformations conformes. L'algebre des transformations conformes de l'espace-temps presente une caracteristique remarquable: en deux dimensions elle possede un nombre infini de generateurs. Cette propriete impose de telles conditions aux fonctions de correlations qu'il est possible de les evaluer sans aucune approximation. Les champs des theories conformes appartiennent a des representations de plus haut poids de l'algebre de Virasoro, une extension centrale de l'algebre conforme du plan. Ces representations sont etiquetees par h, le poids conforme de leur vecteur de plus haut poids, et par la charge centrale c, le facteur de l'extension centrale, commune a toutes les representations d'une meme theorie. Les theories conformes minimales sont constituees d'un nombre fini de representations. Parmi celles-ci se trouvent des theories unitaires dont les representation forment la serie discrete de l'algebre de Virasoro; leur poids h a la forme h_{p,q}(m)=[ (p(m+1) -qm)^2-1] (4m(m+1)), ou p,q et m sont des entiers positifs et p+q= 2. Ces representations possedent un sous-espace invariant engendre par deux sous-representations avec h_1=h_{p,q} + pq et h_2=h_{p,q} + (m-p)(m+1-q) dont chacun des vecteurs de plus haut poids portent le nom de vecteur singulier et sont notes respectivement |Psi _{p,q}> et |Psi_{m-p,m+1-q}>. . Les theories super-conformes sont une version super-symetrique des theories conformes. Leurs champs appartiennent a des representation de plus haut poids de l'algebre de Neveu-Schwarz, une des deux extensions super -symetriques de l'algebre de Virasoro. Les theories super -conformes minimales possedent la meme structure que les theories conformes minimales.

    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.

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

    International Nuclear Information System (INIS)

    Reich, K.H.

    1983-12-01

    The conceptual design of heavy ion fusion drivers has now reached a state, where the overall approach has become fairly clear. One design features an RF linac plus current and beam multiplication rings. The present remarks concern the assignment of multiturn injection, beam storage and bunching to an optimized number of rings and transport lines, as well as some criteria for their designs. The main parameter constraints are discussed, showing how they can be met, although there is little flexibility at the present stage of understanding and technology.

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

    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.

    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.

Le cadre politico-juridique favorable aux migrations antillaises vers leur métropole rend compte de la vigueur des courants migratoires issus des territoires dépendants de la région ainsi que de leur orientation quasi-exclusive vers les métropoles. La problématique migratoire se pose en des termes différents concernant les territoires indépendants. L’analyse de trois populations caribéennes – les Portoricains, les Franco-antillais, les Haïtiens – interroge la particularité des contextes politico-institutionnels des sociétés d’origine en lien avec les modalités singulières de leur colonisation. Au regard de la remarquable diversité des statuts politiques des territoires de la Caraïbe, l’analyse du lien entre migration et fait colonial nécessite de s’interroger sur l’influence de ces derniers sur la temporalité, l’ampleur, la composition et la spatialisation des mouvements de populations.The making of Caribbean societies is indissociable from long-term migration movements. The favourable politico-legal framework of Caribbean migrations towards their metropoles accounts for the strength of migration streams from politically dependent territories in the region. It also accounts for their spatial configuration as ‘migratory couples’. The issue is different as far as independent territories are concerned. The analysis of three Caribbean populations – Puerto Ricans, French West Indians, Haitians – questions the particularity of the politico-institutional contexts of source societies in relation with the singular modalities of their colonization. Given the remarkable diversity of political statuses in the Caribbean, the analysis of the relation between migration and the colonial history requires to question the influence of these statuses on the temporality, the scale, the

    The current trend towards establishing the national programme on food irradiation appears to be maturing with great interest in fundamental and practical problems. Efforts of the Atomic Energy Commission to devise a programme on development studies, and their practical application, which will probably commence in 1967, are now being made. The collaboration of researchers in this field has resulted in the setting-up of the Japanese Research Association. for Food Irradiation. This organization is expected to play an important role in promoting the national programme. At present there are in Japan about 30 kCi-scale sources of radioisotopes, and almost the same number of electron generators, including some pilot-scale irradiation facilities. Practical studies on food irradiation in Japan are classified into three categories, in terms of their purpose. The first is radiation preservation, to which major efforts have been devoted. Sprout inhibition of potatoes, onions and sweet potatoes, disinfestation of rice, wheat and their products, low-dose treatment of vacuum-sealed fish and shell-fish with doses of less than 0.5 Mrad, and of some fruits, such as strawberry and orange, are the examples which are considered to be potential subjects for radiation treatment. The first interesting observation was in rice irradiation where, at 5000 to 20 000 rad disinfestation dose, quality changes detectable immediately after irradiation became insignificant after eight months' storage according to the statistical analysis of organoleptic data. The second was in connection with studies on the elimination of harmful biological and biochemical factors in foods from the viewpoint of public health. Radiation sensitivity of the toxin produced by Cl. botulinum, Type E| was investigated in studying the wholesomeness of irradiated foods. The third was concerned with the utilization of the chemical effect of radiation. For example, studies were made of the irradiation of marine algae with 0

    The present communication is devoted to a body of theoretical and experimental work carried out at the C.E.A. with the aim of adding to the current knowledge on the evolution of the reactivity (during fuel irradiation) in natural or slightly enriched Uranium reactors. The difficulties of performing direct experiments on large amounts of irradiated fuels are reviewed - especially in operating power reactors - and the necessity is underlined for fundamental research in two directions: on one hand, the change in the composition of the fuels (chains of heavy nuclei, fission products), and on the other hand the effect of changes in composition on the neutron balance. Before presenting three types of experiments which have been carried out, the importance of the problems associated with the neutron spectra is stressed and the practical methods used for the calculations are briefly described. The systematic irradiation of several types of fuel, followed by their chemical and isotopic analysis has been going on for several years. An outline of the experimental programme is given with a description of the methods employed: {alpha}, {beta}, {gamma} chain for the preparation of samples determination of the plutonium content by coulometry and double isotopic dilution, separation of Boron used in some cases for the measurement of integrated neutron densities. The interpretation of the measurements is discussed with some examples. A second and more recent series of experiments deals with the investigation of lattices, using synthetic fuels (Uranium-Plutonium alloys) as compared to slightly depleted or enriched Uranium Various experiments are considered on heavy water and on cold graphite, then on graphite heated up to 500 C Some results already obtained are listed. These experiments, requiring nearly a metric ton of each type of fuel cannot be pursued in a systematic manner. This is why is developed since several years a method of differential measurement by oscillation, which

    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.

  2. Remarkable reduction of thermal conductivity in phosphorene phononic crystal

    2016-01-01

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

    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.

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

    2012-02-01

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

  5. Remark on state vector construction when flavor mixing exists

    International Nuclear Information System (INIS)

    2006-01-01

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

    The first three chapters of these lecture notes are devoted to generalities concerning current algebra. The weak currents are defined, and their main properties given (V-A hypothesis, conserved vector current, selection rules, partially conserved axial current,...). The SU (3) x SU (3) algebra of Gell-Mann is introduced, and the general properties of the non-leptonic weak Hamiltonian are discussed. Chapters 4 to 9 are devoted to some important applications of the algebra. First one proves the Adler- Weisberger formula, in two different ways, by either the infinite momentum frame, or the near-by singularities method. In the others chapters, the latter method is the only one used. The following topics are successively dealt with: semi leptonic decays of K mesons and hyperons, Kroll- Ruderman theorem, non leptonic decays of K mesons and hyperons ( {delta}I = 1/2 rule), low energy theorems concerning processes with emission (or absorption) of a pion or a photon, super-convergence sum rules, and finally, neutrino reactions.

After describing the basic technique used in sediment movement studies (injection of a labelled sediment or a simulator into the current, followed by tracking the radioactivity), the author enumerates as fully as possible the problems that can be solved with the help of this technique. Essentially, these problems fall into two groups: 1. Problems related to civil engineering works in coastal areas: the siltation of harbour channels and docks, the formation of banks and bars, the choice of sites for disposing of dredged sediment, the siting of ports, coastline protection, etc. Problems associated with civil engineering works in and near rivers; siting of the water intakes of hydroelectric and nuclear power stations, the effects of construction work on the transport of solids, the construction of dams, the protection of river banks, the construction of jetties, the siltation of lakes, etc. Problems common to these include the transport of effluent and the calibration of hydraulic models. The bibliography is based mainly on fairly recent references and on current research work. 2. Problems related to basic or applied research conducted mainly by universities and research centres: the study of the Quarternary of a particular region, pure sedimentology, the investigation of major sediment transport currents, the confirmation or refutation of transport theories, research into fundamental transport phenomena associated with channel experiments. After referring to the possible exploitation of natural tracers (contained in radioactive waste and fallout), the author discusses the technical aspects of using artificial tracers: the choice of radioisotope

    . The January 1910's flood is one of these remarkable floods. This event is foremost known for its aftermaths on the Seine basin, where the flood remains the strongest recorded in Paris since 1658. However, its impacts were also widespread to France's Eastern regions (Martin, 2001). To demonstrate the evaluation grid's interest, we propose a deep analysis of the 1910's river flood with the integration of historical documentation. The approach focus on eastern France where the flood remains the highest recorded for several rivers but were often neglected by scientists in favor of Paris's flood. Through a transdisciplinary research based on the evaluation grid method, we will describe the January 1910 flood event and define why it can be considered as a remarkable flood for these regions.

    2015-06-01

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

    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.

    The uranium bearing shale ore-body at St-Hippolyte was mainly proved by drillings, the results of which were studied through statistical methods. The author gives an account of his conclusions regarding the distribution of mineralization, its origin and, the estimate of reserves. The uranium mineralization is irregularly distributed in shales. On a vertical line, levels could be singled out: they are similar, as far as lithology is concerned, but each of them is characterized by a grade-population, according to a lognormal distribution. Horizontally, a connection is noted between grades and the overlying barren sandstone bed. These considerations, as well as a statistical study of U/Ra ratio, induced the author to consider that the mineralization of the richest level has an hydrothermal origin. It is only through an uranium diffusion from that level that the others are mineralized. The uranium which is contained in poorest beds has a syn-genetic origin. Furthermore, statistical methods bring us to an evaluation of reserves. In such a case, the evaluation is equivalent to the ore obtained by common arithmetical methods. Moreover, we are able to state precisely the upper and lower limits where a true tonnage or a true grade could be given with a definite value of statistical certainty. Then the author has been able to study the separation of reserves in grade-groups and to foresee the effect of sorting in connection with the lower possible grade and with extraction units (wagons, lorries, etc...), on which the sorting will be done. To conclude, the author indicates the value of both classical and statistical methods. These two techniques are completing each other and they solve different problems.

    Full Text Available Des méthodes de résolution analytiques et numériques ont été proposées, pour déterminer les distributions de contraintes autour de forages pétroliers dans le cas de matériaux peu résistants. Le calcul de ces distributions aboutit à la détermination des pressions de fracturation. Le critère de plasticité de Mohr-Coulomb a été choisi pour la résolution analytique. Cette étude permet d'établir trois schémas types de distribution de contraintes, au moment de la fracturation, pour un régime permanent d'écoulement. La géométrie axisymétrique du modèle a permis d'utiliser une méthode numérique par schéma aux différences finies. La loi de comportement du matériau est déduite du critère de plasticité de Drucker. Cette résolution permet le chargement incrémental en pression dans le forage et de simuler une injection rapide par un couplage simplifié fluide-squelette. Le modèle élastoplastique à deux surfaces de charge de Lade-Shao a finalement été retenu pour décrire l'écrouissage du matériau. La comparaison des résultats des différentes méthodes de calcul s'effectue sur la base de l'influence respective du coefficient de poussée au repos Ko, du coefficient de Poisson et de la résistance à la compression, Co, du matériau. Analytical and numerical methods are proposed, in order to determine stresses distribution around borehole for axisymetric problems in the case of low strengh materials.

    This final report describes the results of the techno-economic accompanying research of the competition of bioenergy regions. The competition was realized as a three-year funding project of the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), wherein the DBFZ analyzed the bioenergy development in the project regions and effects for regional development. The aim of the techno-economic accompanying research was to evaluate the project regions regarding the use of bioenergy. To this end, the bioenergy plants and supply chains of bioenergy as well as the raw materials used were the focus of investigations. Hereby the comparison between the regions and classification of the national average should be made possible. It was also necessary to be able to make statements about the climate protection contribution of funding the project. Not least the DBFZ supported the office of competition and the regions in answering technical-economic issues. The report is divided into a theoretical part A and the result Part B. After a summary of the results (chapter 1) and a brief overview of important and higher-level indicators (Chapter 2) the background and objectives of the competition are in Part A, first presented (Chapter 3). This is followed by Chapter 4 of the explanation of the methodological approach. Part B contains the results of the accompanying research project. The individual chapters are based respectively on the specific questions or thematic blocks of techno-economic accompanying research (Section 5-8). The final chapter 9 takes a brief look at the second funding phase from 2012 to 2015.

    This paper describes a study of the physico-chemical state of radio-cerium in dilute solutions on the tracer scale, as a function of the pH of the solution. The way in which this radioelement is transported in the blood is studied in vitro and in vivo, with reference to the ionic or colloidal state of the radio-cerium used. The distribution of cerium amongst the various components of the blood is studied by a new method of blood fractionation and by paper electrophoresis. Evidence of a cerium globulin connection is shown in the case of ionic cerium. A study of the initial distribution of radio-cerium in rats, after intravenous administration of ionic or colloidal solutions, shows considerable differences according to the physico-chemical state of the cerium injected.

    The waste from an atomic centre is very varied in nature, in form, and in activity, going from weakly contaminated laboratory waste to objects actuated in a pile and strongly radioactive. After one year's working of a pilot plant, a factory has been built, in which solide waste is treated and then conditioned in concrete blocks. The present communication describes the treatment and conditioning techniques in this factory which uses to a maximum remotely controlled operation.

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

    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.

    Full Text Available Osteoporose ist in hohem Maß genetisch determiniert. Neue Wege der molekularbiologischen Forschung haben sich in den letzten Jahren auf diesem Gebiet etabliert. "Gene mapping" mit polymorphen genetischen Markern auf der Suche nach Phänotyp-assoziierten Genen ist ein aufwendiges, aber vielversprechendes Verfahren und wird durch die Erkenntnisse des Human Genome Projects beschleunigt. So wurde jüngst u. a. das Low-density Lipoprotein 5-Gen als wichtig für den Knochenstoffwechsel identifiziert. Kandidaten-gene wie Hormonrezeptor-, Cytokin- oder Kollagen-Gene werden hinsichtlich ihrer Gen-Gen- und Gen-Umwelt- Interaktionen untersucht und erlauben neue funktionelle Einsichten in Erkrankungen des Knochenstoffwechsels. Mutationen der Kollagen-Gene sind bei einigen seltenen Erkrankungen, wie dem Osteoporose-Pseudogliom-Syndrom oder der Osteogenesis imperfecta gefunden worden, könnten aber auch für häufige Varianten von Bindegewebsstörungen wie der congenitalen Hüftdysplasie verantwortlich sein, die etwa 10 % der weiblichen kaukasischen Bevölkerung in unterschiedlichem Ausmaß betrifft. Osteoporose am Schenkelhals und erhöhte Gelenkslaxizität sowie andere generalisierte Veränderungen des Knochen- und Kollagenstoffwechsels können hier möglicherweise ebenfalls durch Störungen des Kollagen I alpha 1-Gens erklärt werden. In Summe können wir zahlreiche neue Einsichten in die Pathophysiologie des Skelettsystems erwarten, die uns auch neue Zugangswege für Diagnostik und Therapie unserer Patienten ermöglichen werden.

    Quelle que soit la civilisation à laquelle il appartient, l'être humain cherche dans le ciel des réponses aux questions qu'il se pose sur son origine, son avenir et sa finalité. Le premier mérite de ce livre est de nous rappeler que l'astronomie a commencé ainsi à travers les mythes célestes imaginés par les Anciens pour expliquer l'ordre du monde et la place qu'ils y occupaient. Mais les savoirs astronomiques passés étaient loin d'être négligeables et certainement pas limités aux seuls travaux des Grecs : c'est ce que l'auteur montre à travers une passionnante enquête, de Stonehenge à Gizeh en passant par Pékin et Mexico, fondée sur l'étude des monuments anciens et des sources écrites encore accessibles. Les tablettes mésopotamiennes, les annales chinoises, les chroniques médiévales, etc. sont en outre d'une singulière utilité pour les astronomes modernes : comment sinon remonter aux variations de la durée du jour au cours des siècles, ou percer la nature de l'explosion qui a frappé tant d'observateurs en 1054 ? Ce livre offre un voyage magnifiquement illustré à travers les âges, entre astronomie et archéologie.

Papaya fruits show promise for gamma-ray control of the Hawaiian fruit fly. Irradiated fruits have 3 to 5 days longer shelf-life than fruits subjected to ethylene dibromide fumigation. The present outlook for the radiation treatment of various fruits and vegetables is discussed. (author) [French] On s'interesse beaucoup au fait que l'irradiation des fruits et legumes apres la recolte permet de lutter contre les maladies affectant la commercialisation, de detruire les insectes qui y sont presents, de retarder la maturation et de prevenir la germination. L'action fongicide des rayonnements est particulierement interessante en raison de ses effets therapeutiques. Malheureusement, dans de nombreux cas, la dose applicable est considerablement reduite par la sensibilite de l'hote. La tolerance a l'irradiation varie suivant l'espece et la variete, et elle est fonction du degre de maturation au moment du traitement. Si les denrees alimentaires sont destinees a etre enmagasinees, il est parfois necessaire de n'utiliser qu'une faible dose de rayonnements, pour eviter des effets nuisibles differes. La suppression d'un agent pathogene est essentiellement fonction de sa sensibilite aux rayonnements et du degre d'alteration. En regle generale, dans le cas des alterations de faible etendue provoquees par des champignons, une grande partie des organismes pathogenes sont inactives et les autres se developpent plus lentement. A ce jour, l'irradiation a donne les meilleurs resultats dans les cas ou les problemes poses par la presence d'organismes pathogenes etaient particulierement graves, par exemple, pour le traitement des denrees tres perissables que l'on recolte lorsqu'elles sont parvenues a maturation et qui presentent des alterations bien definies au moment de la recolte.

    West, S.C.

    1997-01-01

    In his opening address, the Alberta Minister of Energy outlined the role of the Alberta government in the development of the petrochemical industry in that province. A large portion of Alberta's petrochemical production is based on ethane extracted from natural gas. Several world class petrochemical plant expansions are planned for the near future in an effort to maximize the economic benefits from gas production. The goal of the Alberta government is to maximize the economic benefits from gas production and value added gas liquids upgrading within the province to benefit all Albertans. At the same time, gas producers want to sell their product at full market value, while Alberta's petrochemical industry is interested in securing an adequate supply of ethane to allow the industry to expand to its full potential in a global marketplace. According to the Minister, these goals will be best achieved through cooperation between the government, regulatory authorities, gas producers, petrochemical producers and pipeline companies. Simplification of the royalty regime, pipeline tolling issues, the jurisdictional issues yet to be resolved with the federal government regarding ways to respond to climate change challenge, and natural gas/electricity convergence were some of the other issues addressed by the Minister

  2. Remarks concerning the determination of burn-out in research reactors

    International Nuclear Information System (INIS)

    Fabrega, S.; Lafay, J.; Vernier, P.

    1969-01-01

    The operation of reactors cooled by water at low pressure is quite safe as long as the margin existing between nominal conditions and certain conditions leading to burn-out is known. The phenomena which can cause such an effect are defined here. A distinction is made between primary burnout, which is completely localized, and secondary burn-up. This latter can be the result either of a flow reduction, or of the onset of a hydrodynamic oscillation, or again of the attainment of sonic flow conditions. Once the planner is aware of the varied nature of these phenomena, it is shown which are the precautions to be taken during the construction and operation of an out-of-pile test-loop so that such phenomena may subsequently be detected. In the first experiment on a loop with a 600 x 53 x 2 mm rectangular channel, there resulted either primary (critical) burn-out (down-stream pressurization), or secondary critical burn-out (up-stream pressurization) resulting from instability. Another experiment has shown that in the case of the reactor PEGASE, critical burn-out was due to flow reduction in nominal and steady-state operational conditions. (authors) [fr

    Full Text Available Different linguistic theories of meaning (semantic theories imply different methods to discuss meaning. Discussing meaning is what legal practitioners frequently do to decide legal issues and, subsequently, legal scholars analyse in their studies these discursive practices of parties, judges and legal experts. Such scholarly analysis reveals a methodical choice on how to discuss meaning and therefore implies positioning oneself towards a semantic theory of meaning, whether the scholar is aware of this or not. Legal practitioners may not be bound to be consistent in their commitment to semantic theories, as their task is to decide legal issues. Legal scholars, however, should be consistent because commitment to a semantic theory implies a distinct position towards important legal theoretical doctrines. In this paper three examples are discussed that require an articulated position of the legal scholar because the discursive practices of legal practitioners show inconsistencies. For each of these examples it can be shown that a scholar’s methodic choice implies commitment to a specific semantic theory, and that adopting such a theory implies a distinct position towards the meaning of the Rule of Law, the separation of powers doctrine and the institutional position of the judge.

  5. Calvin as an exegete of Scripture: a few remarks with reference to Calvin research in general

    Directory of Open Access Journals (Sweden)

    V. E. d’Assonville

    2010-07-01

    Full Text Available Calvin did not start his famous vocation as an interpreter of Scripture with Scripture itself. After a thorough training in interpreting classical literature as a philologist, he made his debut before turning 23, with a highly respected commentary on Seneca’s “De Clementia”. His focus shifted to Scripture shortly thereafter. Certain features of his exegetical approach as part of his “Word of God theology” can thus be observed, especially as they relate to his use of the concept of “doctrina”. His exegesis used not only the principle of “sola Scriptura” as point of departure, but also the principle of “tota Scriptura”, i.e. to take the whole of Scripture into account when expositing a certain biblical text. For Calvin the original intention of the writer of a particular (Bible book is of crucial importance. The exegesis should be done using a sound theological-methodological, historical-grammatical method. Knowledge of the original lang- uages of Scripture is therefore a prerequisite for any exegesis. In his exegesis Calvin emphasises the point that Scripture as the Word of God and the Holy Spirit cannot be separated. As the truth is simple, Calvin avoids any traces of allegory in his exegetical activities and aims to keep his exegesis and ex- position of Scripture simple, brief, clear and understandable – exegesis should always exhibit the quality of clarity and brevity. In all exegesis, Scripture as the Word of God should be accepted as the final authority on any issue, not the church as institute.

  6. La production mondiale des vins

    Directory of Open Access Journals (Sweden)

    Pierre GALET

    1970-06-01

    On sait peu de choses précises sur l'origine de la culture de la vigne en Gaule. Il est probable qu'il existait des lambrusques sauvages dans les forêts et les sous-bois dont les habitants récoltaient les raisins pour les consommer à l'état frais et peut-être en tiraient-ils aussi une boisson fermentée comme ils le faisaient pour l'orge ou pour le miel (hydromel. Il est vraisemblable aussi que les navigateurs phocéens, venus commercer sur les rivages de la Méditerranée, apportèrent du vin aux gaulois, leur apprirent à tailler la vigne et finalement, en établissant des comptoirs, amenèrent des boutures de vignes de leur propre pays. On sait que les gaulois apprécièrent très vite le vin et ce fut une des raisons de leurs invasion de la Toscane pour y consommer sur place cette « boisson magique ». Plus tard avec l'occupation romaine la culture de la vigne s'étendit dans toute la province narbonnaise, dans la vallée du Rhône jusqu'aux portes de Lyon, puis en Aquitaine. A leur tour les romains se mirent à apprécier les vins gaulois, de qualité supérieure à ceux récoltés en Italie sur les Hautains. A l'aide de la navigation fluviale sur le Rhône les vins gagnèrent Rome, ainsi que ceux embarqués dans les petits ports du rivage méditerranéen. Puis au cours des siècles et grâce notamment aux religieux catholiques la vigne se répandit dans toutes les provinces. A la veille de la Révolution, en 1788, on estimait la superficie cultivée à 1.567.000 hectares, produisant 27 millions d'hectolitres. Au cours du XIXe siècle, les plantations augmentèrent en raison des facilités de transport que permettait l'établissement des lignes de chemin de fer. Le ravitaillement des grandes villes fut assuré par la création d'un important vignoble dans le Midi. En 1875, la superficie cultivée dépassait 2,4 millions d'hectares et la France produisit 83,8 millions d'hectolitres, record absolu qui ne fut jamais plus atteint depuis. La crise phyllox

    Full Text Available Cet article, résultat d’une enquête sur des associations familiales catholiques, en France et au Portugal, se propose de montrer à quelles conditions des mouvements conservateurs peuvent favoriser la prise de responsabilité des femmes. Dans ces mouvements où l’adhésion se fait en couple et où la différence de nature entre les sexes est en permanence réaffirmée, on observe une nette division sexuelle du travail militant. Les postes les plus prestigieux sont occupés par les hommes, qui sont également majoritairement en charge des tâches de réflexion et d’impulsion politique. Les femmes, quant à elles, prennent en charge l’essentiel des services fournis aux familles, ainsi que la plus grande partie des tâches d’organisation et d’exécution. Cependant, certaines femmes peuvent connaître une ascension très rapide au sein des mouvements et traverser les frontières de la division sexuelle du travail, à condition de disposer d’un capital social important et, surtout, d’une expérience professionnelle. Pour les femmes, peu nombreuses, qui cumulent ces propriétés, l’engagement dans ces mouvements familiaux conservateurs peut constituer le point de départ d’une véritable carrière militante et politique.Este artículo es el resultado de una investigación acerca de unas asociaciones familiares católicas, en Francia y en Portugal.

    The research project was started with the objective of developing the essential geological-technical-technological parts of the utilisation of highly-mineralised thermal waters for heating. It is based on the findings from the drilling and testing of 29 deep geothermal wells, the erection and operation of Geothermal Heating Stations in Northeast Germany until 1990. The operation of the Waren (Mueritz) and Neubrandenburg Geothermal Heating Stations including their modernisation and the solution of problems which occurred sometimes give proof of the principal technical-technological implementability of thermal water utilisation for energetic purposes. Matter of concern is the recirculation of the thermal water after being used for balneological purposes to the main flow of water used for energetic purposes without affecting subsequent reinjection. The conditioning of the thermal water before and after use for bathing and balneo-therapeutic purposes is another problrm. The essential results are presented here. (orig.)

    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.

    The temperatures needed to produce thermonuclear reactions are of the order of several million degrees Kelvin. Devising methods for measuring such temperatures has been the subject of research in many countries. In order to present the problem clearly and to demonstrate its importance, the author reviews the various conditions which must be fulfilled in order that reactions may be qualified as thermonuclear. The relationship between the temperature and the cross-section of the reactions is studied, and it is shown that the notion of temperature in the plasmas is complex, which leads to a consideration of the temperature of the ions and that of the electrons. None of the methods for the temperature measurements is completely satisfactory because of the hypotheses which must be made, and which are seldom fulfilled during high-intensity discharges in the plasmas. In practice it is necessary to use several methods simultaneously. (author) [French] Les temperatures necessaires pour produire des reactions thermonucleaires sont de l'ordre de plusieurs millions de degres Kelvin. Les methodes envisagees pour mesurer ces temperatures font l'objet de recherches dans de nombreux pays. Afin de preciser le probleme et de montrer son importance, l'auteur rappelle les conditions qui doivent etre reunies pour que des reactions puissent etre qualifiees thermonucleaires. Il etudie la relation entre la temperature et la section efficace des reactions et montre que la notion de temperature dans les plasmas est complexe, ce qui amene a considerer la temperature des ions et celle des electrons. Aucune des methodes de mesure des temperatures n'est completement satisfaisante en raison des hypotheses qu'elles exigent et qui sont rarement realisees lors des decharges a haute intensite dans les plasmas. En pratique, il est necessaire d'utiliser plusieurs methodes simultanement. (auteur)

    An overview is presented of applications of multicharged-ion electron capture and, through the qualitative assessment of availability of information, the general status of current understanding of such capture. A chart is given on which the various ion collision processes are related to other pertinent fields of physical research notably fusion, astrophysics, the solar corona, and lasers. The production and transport of ions is also noted. The symposium considers collision velocities less than 4 x 10 8 cm/s, where the capture cross sections are largest and where most of the available results are quite recent

    1996-01-01

    Helen Hart was a Professor of Plant Pathology at the University of Minnesota from 1924 until retirement in 1966. Born in Janeville, Wisconsin, she died at Grants Pass, Oregon. Her scholarly research concentrated on wheat stem rust to understand host pathogen relationships and to develop rust-resistant cultivars. She did not teach formal courses but was heavily involved in making seminars a vital part of instruction, in teaching languages needed for graduate studies, and as an informal advisor for most rust research theses. She had common sense, excellent scientific judgment, and sound instincts on personnel matters that served the department well. A talented science writer, Hart served as editor of hundreds of theses and departmental manuscripts for publication. Her writing and editing skills were used as associate editor of Phytopathology for two years and as editor-in-chief from 1944-1951. A strong advocate of The American Phytopathological Society, Helen Hart served on Council for 12 years and as President in 1956. Helen Hart was a great professional scientist who had a far-reaching impact on plant pathology during the twentieth century.

    Because of the low rate of water renewal in the recipient, Roskilde Fiord, an efficient decontamination plant incorporating an evaporator has been constructed at the Risoe research establishment. It is intended that the activity of the fiord-water at a distance of ten metres from the discharge point shall be less than one-tenth of the drinking-water tolerance. This will correspond to ca. 1 millicurie per month contained in ca. 5000 m{sup 3} of effluent. A description of the control and collection of laboratory effluents, of the decontamination plant and of the residue storage building will be given. The results of current experiments dealing with the decontamination factor and the economic aspects of the problem will also be given.

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

    Science.gov (United States)

    2004-05-01

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

Puis plus tard, à chaque avance de la colonisation, les vignes se répandirent sur les bords du Danube et dans les vallées latérales, l'extension étant favorisée par les communautés religieuses catholiques qui devinrent propriétaires de grands vignobles.

    This research aimed at improving fast-neutron electronic detectors based on n-p elastic scattering. The first part concerns proportional counters; careful constructional methods have made it possible to plot mono-energetic neutron spectra in the range 700 keV - 3 MeV with a resolution of 7 per cent. The second part concerns scintillation counters: an organic scintillator and an inorganic scintillator covered with a thin layer of a scattering agent. An exact study of the types of scintillation has made it possible to develop efficient discriminator circuits. Different neutron spectra plotted in the presence of a strong gamma background are presented. The last part deals with the development of form discrimination methods for the study, in the actual beam, of the elastic scattering of 14.58 MeV electrons. With hydrogen, the distribution f ({phi}) of the recoil protons is f({phi}) = 1 + 0.034 cos {phi} + 0.042 cos{sup 2} {phi}. With tritium the scattering is strongly anisotropic; the curve representing the variation of the differential cross-section for the elastic scattering in the centre of mass system is obtained with a target containing 1 cm{sup 3} of tritium.

  10. The Remarkable Metrological History of Radiocarbon Dating [II].

    Currie, Lloyd A

    2004-01-01

    This article traces the metrological history of radiocarbon, from the initial breakthrough devised by Libby, to minor (evolutionary) and major (revolutionary) advances that have brought (14)C measurement from a crude, bulk [8 g carbon] dating tool, to a refined probe for dating tiny amounts of precious artifacts, and for "molecular dating" at the 10 µg to 100 µg level. The metrological advances led to opportunities and surprises, such as the non-monotonic dendrochronological calibration curve and the "bomb effect," that gave rise to new multidisciplinary areas of application, ranging from archaeology and anthropology to cosmic ray physics to oceanography to apportionment of anthropogenic pollutants to the reconstruction of environmental history. Beyond the specific topic of natural (14)C, it is hoped that this account may serve as a metaphor for young scientists, illustrating that just when a scientific discipline may appear to be approaching maturity, unanticipated metrological advances in their own chosen fields, and unanticipated anthropogenic or natural chemical events in the environment, can spawn new areas of research having exciting theoretical and practical implications.

    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)

    La fabrication de l'aluminium est realisee dans une cellule d'electrolyse, et cette operation utilise des anodes en carbone. L'evaluation de la qualite de ces anodes reste indispensable avant leur utilisation. La presence des fissures dans les anodes provoque une perturbation du procede l'electrolyse et une diminution de sa performance. Ce projet a ete entrepris pour determiner l'impact des differents parametres de procedes de fabrication des anodes sur la fissuration des anodes denses. Ces parametres incluent ceux de la fabrication des anodes crues, des proprietes des matieres premieres et de la cuisson. Une recherche bibliographique a ete effectuee sur tous les aspects de la fissuration des anodes en carbone pour compiler les travaux anterieurs. Une methodologie detaillee a ete mise au point pour faciliter le deroulement des travaux et atteindre les objectifs vises. La majorite de ce document est reservee pour la discussion des resultats obtenus au laboratoire de l'UQAC et au niveau industriel. Concernant les etudes realisees a l'UQAC, une partie des travaux experimentaux est reservee a la recherche des differents mecanismes de fissuration dans les anodes denses utilisees dans l'industrie d'aluminium. L'approche etait d'abord basee sur la caracterisation qualitative du mecanisme de la fissuration en surface et en profondeur. Puis, une caracterisation quantitative a ete realisee pour la determination de la distribution de la largeur de la fissure sur toute sa longueur, ainsi que le pourcentage de sa surface par rapport a la surface totale de l'echantillon. Cette etude a ete realisee par le biais de la technique d'analyse d'image utilisee pour caracteriser la fissuration d'un echantillon d'anode cuite. L'analyse surfacique et en profondeur de cet echantillon a permis de voir clairement la formation des fissures sur une grande partie de la surface analysee. L'autre partie des travaux est basee sur la caracterisation des defauts dans des echantillons d'anodes crues
