    Soviet theater nuclear forces were a major pillar of Soviet superpower strength, rising sharply under Krushchev in the latter 1950s to their zenith under Brezhnev twenty years later. Most recently they have begun their decline under Gorbachev, and while not yet facing extinction, may be headed for a much reduced role under the new thinking in the USSR. This paper deals with the Soviet TNF in six periods of their life: The Post-war Stalin Period (1945-1953), the Post-Stalin Period (1953-1955), The Transition Period (1955-1959), The Period of Nuclear Revolution (1960-1964), The Period of Modern TNF Planning (1965-1980), and The Period of Non-nuclear Planning (1980-1987)

    In the brief period between May 1978 and December 12, 1979, U.S. policy, and the policy of the NATO Alliance, toward theater nuclear forces (TNF) changed dramatically. The consequences of this change now dominate the political agenda in East-West (and West-West) relations. The ultimate outcome of the now renamed intermediate-range nuclear force (INF) debate will have far-reaching consequences for the future of the Atlantic Alliance. How did this issue emerge? Why did the US change its policy? How did it work with its Alliance to change NATO policy? These questions, among others, are now figuring in the debate. The answers to these questions are discussed in detail

    To determine the safety of definitive in-theater facial fracture repair on American military personnel wounded during Operation Iraqi Freedom. A retrospective review of all patients with head and neck trauma treated at the 322nd Expeditionary Medical Group/Air Force Theater Hospital, Balad Air Base, Iraq, from May 7, 2005, through September 18, 2005, was performed. This study focused on the outcomes of wounded American military personnel whose facial fractures were definitively repaired in theater. The criteria used to determine candidacy for definitive in-theater facial fracture repair on American military personnel were (1) the fracture site was exposed through either a soft tissue wound or because of an adjacent surgical approach, (2) treatment would not delay evacuation from theater, and (3) treatment would allow the military member to remain in theater. From May 2005 to September 2005, 207 patients were taken to the operating room and required 388 procedures. A total of 175 patients (85%) were operated on for traumatic injuries, and 52 of these patients required open reduction and internal fixation (ORIF) of a facial fracture. Of the 52 patients who underwent an ORIF, 17 were American military personnel. Of the 17 American patients who were definitively treated for their facial fractures in theater, 16 were contacted and/or followed up on the global military medical database. None of these patients developed an Acinetobacter baumannii infection or had a complication caused by the definitive in-theater ORIF. The range of follow-up was 2 months to 11 months, with a mean of 8.3 months. Definitive repair of facial fractures with ORIF on American military personnel in theater is advised when the aforementioned criteria are observed. An otolaryngologist is a crucial member of the head and neck trauma team.

    In this paper the present status of the meson theory of nuclear forces is reviewed. After some introductory remarks about the relevance of the meson exchange concept in the era of QCD and the empirical features of the NN interaction, the exciting history of nuclear forces is briefly outlined. In the main part, the author gives the basic physical ideas and sketch the derivation of the one-boson-exchange model of the nuclear force, in the Feynman approach. Secondly we describe, in a qualitative way, various necessary extensions, leading to the Bonn model of the N interaction. Finally, points to some interesting pen questions connected with the extended quark structure of the hadrons, which are topics of current research activity

  13. Various Stagings of Cankar’s Works at the Slovenian National Theater in Ljubljana and Other Slovenian Theaters in the Interwar Period (1918–1941

    Full Text Available Plays by Ivan Cankar unequivocally marked Slovenian theater in the period from 1918 to 1941. In addition to Shakespeare’s works, it was Cankar’s plays that were most frequently performed on the Slovenian stage. His works especially appealed to directors that were seeking deeper, symbolic meanings of the text, which they tried to present to the audience to the best of their ability. Thus, Cankar’s narrative was intensified through directing and acting, whereas the scenery was of secondary importance in most performances. These mostly included painted scenes or backdrops to represent the setting. Only the stagings of Pohujšanje v dolini Šentflorjanski (The Scandal in the St. Florian Valley, Kralj na Betajnovi (The King of Betajnova, Hlapec Jernej in njegova pravica (The Servant Jernej and His Justice, and Lepa Vida (The Beautiful Vida contained more developed scenography. However, until the 1930s, scenery design for Cankar’s plays performed on the professional stage varied between painted backdrops and expressionist sets. It was not until the appearance of the director and scenographer Bojan Stupica that the scenery of these plays reached the boundaries of new realism and modern avant-garde. Until then, an unspoken rule had been in force that the scenery of Cankar’s plays should not extend beyond the boundaries of expressionism. This rule was observed even by the avant-garde painter Avgust Černigoj. However, Cankar’s plays were staged completely differently in workers’ theaters and popular theaters. With new avant-garde staging, they often surpassed the development of theater design in professional theaters, and caught up with contemporary formal ideas in Slovenian and European fine arts. Here, Cankar’s works were staged as anti-political propaganda. In order to better express their new ideas, these theaters also used new tools, such as projectors and film clips, and experimented with spotlights. The most original among these

  18. Judge upholds closing of theater that was site of high-risk sex.

    1995-05-05

    New York City's decision to close a gay movie theater where inspectors found male patrons engaging in unsafe sexual activity with other men was upheld by Justice Marilyn G. Diamond of the Supreme Court in Manhattan. She rejected the theater owner's argument that the city's March 31, 1995 closure of the New David Cinema on West 54th Street violated the Constitution's guarantee of freedom of speech. The city based its action on a provision in the state health code which prohibits oral, anal or vaginal sex in commercial establishments. Despite several warnings from the city, the movie house did not follow the demands that it move forcefully to prevent high-risk sexual activity among patrons. The New David was one of two theaters and one sex club shut down by the Health Department in recent weeks, but the only one still closed at press time. Some gay activists contend the action was unjustified, since most of the sex that occurs in those establishments in consensual and involves solo or mutual masturbation. Others point out that a good deal of unsafe sex does occur. Because men often have several sexual liaisons during a single night at a theater or club, the risk of HIV transmission is magnified many-fold.

    1977-01-01

    The charge symmetry breaking (CSB) component of the nuclear forces yields the charge asymmetric term Esub(a)(N-Z)/A in the nuclear binding energy of nuclear matter. Calculation performed with several models of the CSB nuclear forces, and accounting for the strong short-range two-body correlations, gives Esub(a) approximately -0.2 MeV at the normal nuclear density. The charge asymmetry of the effective nucleon-nucleon interaction is determined primarily by the CSB nuclear forces at the neutron excess, observed in finite nuclei. The exclusion principle and dispersion (self-consistency) effects of the nuclear medium decrease this charge asymmetry. (author)

    Full Text Available The aim of this study is to explore organizational policies and strategies regarding the institutional memory of Belgrade’s repertoire theaters. The concept of institutional (organizational memory has not been developed within the culture of memory theory. The role of theater in the culture of memory has been researched mostly through studies of its repertoire, corresponding to how theaters deal with issues of glory, guilt, or shame. This study explores how theaters rethink their own past and organizational culture, how they use their capacity for re-imagining themselves, for clarifying their role and function in different historical moments. The objective of this research is to identify the main institutional policies and types of strategies used for preserving institutional memory through key narratives of remembering, and key methods of inter-generational transfer. The sample comprises of four Belgrade-based public repertoire theaters: the Yugoslav Dramatic Theater (JDP, the Belgrade Dramatic Theater (BDP, Atelje 212, and Bitef Theater. Specific attention is given to the means of transmission, of individual (episodic memories into the collective consciousness, influencing organizational cultures and shaping a theater’s identity (semantic memory. Research has shown that there are important differences in active policies of preserving institutional memory among Belgrade’s theaters. Different organizational and programming strategies were implemented in order to safeguard institutional identity and memory, particularly in theaters with a permanent ensemble. The major difference is between theaters whose culture of memory might be called “non-existent” (Bitef, or “in storage” (BDP, and those succeeding in creating a functional memory (JDP, Atelje 212.

    Full Text Available In Japan, most of children haven't read the Fairy Tales or tales of old Japan because the high technology video games are more exciting than most of picture books. But they must be effective to bring up the children's cultivation of aesthetic sensitivity. And we have heard from teachers of elementary schools that most of themes of computer education in school are the operation of Painting Tool or Game Software. To improve these problems and to aid the courses of computer-based education in elementary school, we developed new educational support tool named Cyber Theater. Cyber Theater provides the capability of easy making the 3D-CG animation of children's story by using Script language named CTSL (Cyber Theater Scenario Language. We hope schoolteachers will be able to use Cyber Tales as teaching materials in elementary schools. We also hope that upper-aged students (including junior high school students are able to make their original CG-animation stories as the Creative Lesson.

  7. Three-particle forces and nuclear models

    International Nuclear Information System (INIS)

    Krutov, V.A.

    1980-01-01

    Different nuclear models accounting and unaccounting for three-particle internucleon forces (TIF) are reviewed. At present only two nuclear models use manifestly TIP: the Vautherin-Brink-Skyrme (VBS) model and the model proposed by the author of the review and called the semiphenomenological (SP) nuclear model. There is a short discussion of major drawbacks of models unaccounting for TIF: multiparticle shell model, ''superfluid model'', Harty-Fock calculations with two-particle forces, Bruckner-Hartry-Fock calculations, the relativistic self-consistent nuclear model. The VBS and SP models are discussed in detail. It is concluded, that the employment of TIF even in a very simplified form (extremely short-range) puts away a lot of problems characteristic to models limited by two-particle forces (collapse at iteratious in Hartry-Fock, simultaneous fitting of the binding energy of a nucleus and the binding energy of a nucleon, etc.) and makes it possible to obtain in a rather simple way such nuclear characteristics as nuclear binding energy, nuclear mean square root radii, nucleon density of a nucleus

  9. Nuclear force from string theory

    We compute the nuclear force in a holographic model of QCD on the basis of a D4-D8 brane configuration in type IIA string theory. The repulsive core of nucleons is important in nuclear physics, but its origin has not been well understood in strongly coupled QCD. We find that the string theory via gauge/string duality deduces this repulsive core at a short distance between nucleons. Since baryons in the model are realized as solitons given by Yang-Mills instanton configuration on flavor D8-branes, ADHM construction of two instantons probes well the nucleon interaction at short scale, which provides the nuclear force quantitatively. We obtain a central force, as well as a tensor force, which is strongly repulsive as suggested in experiments and lattice results. In particular, the nucleon-nucleon potential V(r) (as a function of the distance) scales as r -2 , which is peculiar to the holographic model. We compare our results with the one-boson exchange model using the nucleon-nucleon-meson coupling obtained in our previous paper. (author)

  10. New concept for nuclear force: implications for nuclear structure and hadronic processes

    International Nuclear Information System (INIS)

    Kukulin, V.I.

    2005-01-01

    Full text: A new concept for nuclear force is discussed. The concept is based on idea about production of the intermediate six-quark bag (dibaryon) dressed with meson fields main of which are π-, σ-, p-, and ω-fields. The whole approach has been strongly motivated by our previous detailed analysis of various inner contradictions and inconsistencies in the conventional meson-exchange (i.e. Yukawa like) mechanism of nuclear force. The new force model predicts inevitable strong attractive 3N-force of scalar nature originated from σ-exchange between the dressed dibaryon and third nucleon. This new 3N-force has been demonstrated earlier to result in, at least, a half the total binding energy in lightest nuclei and contribute strongly to all nuclear properties like r. m. s. charge radius, nucleon momentum distribution, new electromagnetic currents and leads, very likely, to new understanding of saturation properties in nuclear matter. In the talk many other implications of the suggested new force model in hadronic and nuclear physics will be discussed

  11. Nuclear Forces from Effective Field Theory

    Krebs, H.

    2011-01-01

    Chiral effective field theory allows for a systematic and model-independent derivation of the forces between nucleons in harmony with the symmetries of the quantum chromodynamics. After a brief review on the current status in the development of the chiral nuclear forces I will focus on the role of the Δ-resonance contributions in the nuclear dynamics.We find improvement in the convergence of the chiral expansion of the nuclear forces if we explicitly take into account the Δ-resonance degrees of freedom. The overall results for two-nucleon forces with and without explicit Δ-resonance degrees of freedom are remarkably similar. We discussed the long- and shorter-range N 3 LO contributions to chiral three-nucleon forces. No additional free parameters appear at this order. There are five different topology classes which contribute to the forces. Three of them describe long-range contributions which constitute the first systematic corrections to the leading 2π exchange that appear at N 2 LO. Another two contributions are of a shorter range and include, additionally to an exchange of pions, also one short-range contact interaction and all corresponding 1/m corrections. The requirement of renormalizability leads to unique expressions for N 3 LO contributions to the three-nucleon force (except for 1/m-corrections). We presented the complete N 2 LO analysis of the nuclear forces with explicit Δ-isobar degrees of freedom. Although the overall results in the isospin-conserving case are very similar in the Δ-less and Δ-full theories, we found a much better convergence in all peripheral partial waves once Δ-resonance is explicitly taken into account. The leading CSB contributions to nuclear forces are proportional to nucleon- and Δ-mass splittings. There appear strong cancellations between the two contributions which at leading order yield weaker V III potentials. This effect is, however, entirely compensated at subleading order such that the results in the theories

    YAP is a mechanosensitive transcriptional activator with a critical role in cancer, regeneration, and organ size control. Here, we show that force applied to the nucleus directly drives YAP nuclear translocation by decreasing the mechanical restriction of nuclear pores to molecular transport. Exposure to a stiff environment leads cells to establish a mechanical connection between the nucleus and the cytoskeleton, allowing forces exerted through focal adhesions to reach the nucleus. Force transmission then leads to nuclear flattening, which stretches nuclear pores, reduces their mechanical resistance to molecular transport, and increases YAP nuclear import. The restriction to transport is further regulated by the mechanical stability of the transported protein, which determines both active nuclear transport of YAP and passive transport of small proteins. Our results unveil a mechanosensing mechanism mediated directly by nuclear pores, demonstrated for YAP but with potential general applicability in transcriptional regulation.

  13. Nuclear reaction matrix and nuclear forces

    International Nuclear Information System (INIS)

    Nagata, Sinobu; Bando, Hiroharu; Akaishi, Yoshinori.

    1979-01-01

    An essentially exact method of solution is presented for the reaction- matrix (G-matrix) equation defined with the orthogonalized plane-wave intermediate spectrum for high-lying two-particle states. The accuracy is examined for introduced truncations and also in comparison with the Tsai-Kuo and Sauer methods. Properties of the G-matrix are discussed with emphasis on the relation with the saturation mechanism, especially overall saturation from light to heavy nuclei. Density and starting-energy dependences of the G-matrix are separately extracted and discussed. It is demonstrated that the triplet-even tensor component of the nuclear force is principally responsible for these dependences and hence for the saturation mechanism. In this context different nuclear potentials are used in the renormalized Brueckner calculation for energies of closed-shell nuclei in the harmonic oscillator basis. A semi-phenomenological ''two-body potential'' is devised so that it can reproduce the saturation energies and densities of nuclear matter and finite nuclei in the lowest-order Brueckner treatment. It is composed of a realistic N-N potential and two additional parts; one incorporates the three-body force effect and the other is assumed to embody higher-cluster correlations in G. The tensor component in the triplet-even state of this potential is enhanced by the three-body force effect. The G-matrix is represented in the effective local form and decomposed into central, LS and tensor components. (author)

    Full Text Available Background: Quality communication skills and increased multicultural sensitivity are universal goals, yet teaching them have remained a challenge for educators. Objective: To document the process and participant responses to Interactive Theater when used as a method to teach physician-patient communication and cross-cultural competency. Design, setting, and participants: Three projects are reported. They were collaborations between Theater Delta, the UNC Center for Functional GI and Motility Disorders, the Rome Foundation, the World Gastroenterology Organization, and the American Gastroenterological Association. Outcome measures: 8 forced choice and 6 open ended were collected from each participant using a post-performance evaluation form. Results: Responses to the 8 indicators relating to a positive experience participating in the Interactive Theater. The vast majority either agreed or strongly agreed with the statements on the evaluation form. Written comments explained why. Conclusions: Data indicates that Interactive Theater stimulates constructive dialogue, analysis, solutions, and intended behavior change with regard to communication skills and adapting to patients from multicultural backgrounds. Interactive Theater directly focuses on communication itself (active listening, empathy, recognizing cultural differences, etc. and shows promise as an effective way to improve awareness and skills around these issues.

    Micromechanical sensing of magnetic force was used to detect nuclear magnetic resonance with exceptional sensitivity and spatial resolution. With a 900 angstrom thick silicon nitride cantilever capable of detecting subfemtonewton forces, a single shot sensitivity of 1.6 x 10 13 protons was achieved for an ammonium nitrate sample mounted on the cantilever. A nearby millimeter-size iron particle produced a 600 tesla per meter magnetic field gradient, resulting in a spatial resolution of 2.6 micrometers in one dimension. These results suggest that magnetic force sensing is a viable approach for enhancing the sensitivity and spatial resolution of nuclear magnetic resonance microimaging

This article is a report of nursing students' experience in guiding children through theater in a public nursery located in the interior of São Paulo state. The objective was to report on the benefits of using theatre with children. The methodology to develop the study was a dialogue based on literature review articulated with the account of experience. It was concluded that theater can be used as an important educational tool, diversifying the way of teaching children, surpassing the simple pass on of knowledge, increasing involvement and integration.

    The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

    This short research paper addresses two topics that have emerged in the debate about whether, when, and how to modernize U.S. nuclear forces.1 The first topic relates to the size and scale of the planned nuclear force, with some critics of the modernization plan arguing that the United States is simply replicating the Cold War force for a very different era. The second topic relates to the cost of the modernization effort, with some critics arguing that the cost is unaffordable.2 This paper begins with a review of the changes in the size and scale of U.S. nuclear forces since the Cold War. It then examines the expected costs of modernization in a comparative perspective.

    Full Text Available The anthropology of performance, as understood by Victor Turner, provides interesting perspectives for the analysis of what may be referred to as the "theater of bóias-frias". Conversely, this theater may be of special interest for purposes of rethinking some of the main propositions which have arisen on the borders between anthropology and performance. Considering the specificity of "the practice which calculates the place from which one views things" of this theater, several topics present themselves as guidelines for the text which follows: 1 social dramas, 2 relations between social and aesthetic dramas, 3 symbols and montage, and 4 theater paradigms in anthropology. In this exercise to rethink some of the "classic" contributions of Victor Turner, Erving Goffman, and Richard Schechner, "elective affinities" have been found between, on the one hand, the writings of Walter Benjamin and Brechtian theater, and, on the other, the dramaturgical principles of the bóias-frias.

    This bibliographical note presents a book in which the author, after having recalled the history of the French nuclear force since the first nuclear test in 1960, and outlined the fact that France has been living under the protection of its own nuclear deterrence force since that date, presents the components of this nuclear strike force with its four nuclear submarines equipped to launch new generation missiles, its fifty fighter bomber aircraft equipped with the ASMP-A missile. He presents and discusses the mission of this nuclear force, discusses the relevancy of the deterrence strategy in the present context, and the significance of such a strategy for a European country like France. He wanders whether this strike force is still affordable for our country, which can be its benefits, whether this arsenal remains useful as it has been designed in the Cold War context. He also discusses the disarmament perspectives in an unsteady international environment where power and arms race logics prevail again

    Since 2001, U.S. military personnel and active duty, uniformed physicians providing medical support have been deployed to Afghanistan. Medical toxicologists are among the physicians deployed. There is a paucity of information present in the literature that has documented cases treated by toxicologists in theater. This prospective observational study describes 15 male patients treated in theater by a military medical toxicologist. We performed a prospective observational study in which a medical toxicologist consulted and reported on deployed toxicology cases occurring during a 5-month deployment to Bagram, Afghanistan. Fifteen toxicology cases were collected during the 5-month period. The patients included three Afghan civilians, three U.S. civilians, and nine U.S. military personnel. Eight cases were attempts at recreational euphoria, two were self-harm attempts, two were from performance-enhancing supplements, two were accidental occupational exposures and one was alcohol withdrawal. Methanol was the most common exposure followed by dextromethorphan, supplements, opiates, and chlorine gas. In our study, we found that toxic alcohols and nonprescription medications were the most common exposures. In addition, this is the first study to describe bedside toxicology consults for U.S. combat forces in theater and the use of an observation unit for critically ill patients.

    Latina teen pregnancy rates continue to be a health disparity in the United States. This study evaluated a parenting intervention using interactive theater to facilitate Latino parent-adolescent communication about sexuality and pregnancy prevention. The intervention, conducted in Spanish and with teen actors, consisted of scenes involving the audience. Fifty-nine parents participated in this 3-month prospective study. Spanish measures of comfort with communication, general communication, and parent-child sexual communication were employed comparing paired t tests for each scale. Acceptability of the intervention was assessed and demonstrated. Eighty-six percent of parents used information from the performance to talk to their child. Improvements in general communication (p < .02), sexual communication (p < .001), and comfort (p < .001) occurred. Interactive theater is an innovative approach to facilitate Latino parent communication about sexuality and pregnancy prevention.

    The techniques of adiabatic demagnetization and brute force are described extensively. Special attention is paid to the thermostatic aspects and the problems caused by heat leaks and thermal barriers. Some thermometric experiments on copper are reported concerning the heat exchange between the nuclear spin system and the conduction electron system. A brute force experiment on 95 Nb yielded a nuclear magnetic moment of μ = (6.3 +- 0.1)μsub(n). A feasibility study is made on the use of PrCu 6 hyperfine enhanced paramagnet instead of the paramagnetic salt used as a intermediate cooling stage between the dilution refrigerator and the purely nuclear refrigeration stage. This will allow for experiments of long duration (one hour and more) in the sub-milli-kelvins temperature region

  10. Three-Body Nuclear Forces from a Matrix Model

    2010-01-01

    We compute three-body nuclear forces at short distances by using the nuclear matrix model of holographic QCD proposed in our previous paper with P. Yi. We find that the three-body forces at short distances are repulsive for (a) aligned three neutrons with averaged spins, and (b) aligned proton-proton-neutron / proton-neutron-neutron. These indicate that in dense states of neutrons such as cores of neutron stars, or in Helium-3 / tritium nucleus, the repulsive forces are larger than the ones estimated from two-body forces only.

    During the past two decades, it has been demonstrated that chiral effective field theory represents a powerful tool to deal with nuclear forces in a systematic and model-independent way. Two-, three-, and four-nucleon forces have been derived up to next-to-next-to-next-to-leading order (N 3 LO) and (partially) applied in nuclear few- and many-body systems—with, in general, a good deal of success. This may suggest that we are finally done with the nuclear force problem; but that would be too optimistic. There are still some pretty basic open issues that have been swept under rug and, finally, need our full attention, like the proper renormalization of the two-nucleon potential. Moreover, the order-by-order convergence of the many-body force contributions is at best obscure at this time. (author)

  13. Theater and the Discourse on Power: Jose Rizal’s Participation in Philippine Theater in the Last Decades of the Nineteenth Century

    Apolonio B. Chua

    2007-06-01

    Full Text Available The study focuses on Jose Rizal’s participation in Philippine Theater during the last decades of the nineteenth century. It starts with a careful inventory of attitudes towards existing theater forms and a description of the culture of theater as conceived and imagined in Rizal’s Noli Me Tangere (1887 and El Filibusterismo (1891. In Chapter 20: “The Town Council’s Meeting” in Noli Me Tangere, the study zooms in on the debate on what would be the best and most appropriate theatre piece for the town fiesta. Here, Rizal delineates theater enmeshed in issues of power and Spanish colonialism. He notes as significant the ilustrados’ claim to theatre space and ideology, thereby interrogating Spanish hegemony. The debate becomes the central imagery and situation for Rizal’s analysis and construction of the history of Philippine theater in the novel. Conservative and radical elements duel. The conflict becomes sharper as Rizal continues his critique by putting into his fictional world the very historical actors known at that time; namely, Nemesio Ratia, Jose Carvajal and Praxedes Julia Fernandez (also known as “Yeyeng”. They were part of the comedia troupe hired by the town for the fiesta. In Rizal’s second novel, El Filibusterismo, we encounter the events surrounding the presentation by a French opera troupe in Teatro de Variedades, which Rizal considers as the Manila theater model. The features of this model include a particular ticket system, various kinds of audiences, imported dramatic texts which were largely incomprehensible, actors behaving as actors both on-stage and off-stage, and the Teatro de Variedades space as stage for seizure or possession of power. When the students in the audience stage a walk-out in the theatre of the city and when in provincial San Diego, a stampede cuts short a comedia performance, the interrelationships between society and a discourse of power are revealed.Rizal’s annotations of Philippine

  14. In-theater piracy: finding where the pirate was

    2008-02-01

    Pirate copies of feature films are proliferating on the Internet. DVD rip or screener recording methods involve the duplication of officially distributed media whereas 'cam' versions are illicitly captured with handheld camcorders in movie theaters. Several, complementary, multimedia forensic techniques such as copy identification, forensic tracking marks or sensor forensics can deter those clandestine recordings. In the case of camcorder capture in a theater, the image is often geometrically distorted, the main artifact being the trapezoidal effect, also known as 'keystoning', due to a capture viewing axis not being perpendicular to the screen. In this paper we propose to analyze the geometric distortions in a pirate copy to determine the camcorder viewing angle to the screen perpendicular and derive the approximate position of the pirate in the theater. The problem is first of all geometrically defined, by describing the general projection and capture setup, and by identifying unknown parameters and estimates. The estimation approach based on the identification of an eight-parameter homographic model of the 'keystoning' effect is then presented. A validation experiment based on ground truth collected in a real movie theater is reported, and the accuracy of the proposed method is assessed.

    A brief outline is given of a possible theory of the nuclear force and the strong interactions between elementary particles, which is supposed responsible for nuclear matter. The theory is known as quantum chromodynamics because of its association with a new kind of nuclear charge called colour and its resemblance to quantum electrodynamics. Early ideas on the nuclear force and the emergence of the quark model and the QCD Lagrangian are described first. Then properties of this theory and the problem of quark confinement, the perturbative phase of QCD, and the non-perturbative or confinement phase of QCD and the description of hadrons and their interactions are discussed

Such publications are important for the quantity and the diversity, revealing not only the place occupied by the theater in the capital, but also for the recognition of the press as a means of disclosure of plays, public education and opinion, artist projection, etc, not to mention personal affairs and requests, and the exchange of favors among managers and journalists. Even more, the press production of the dramatic amateurs clubs demonstrate the understanding of its role in the dissemination of ways to act and think beyond the stage and in the everyday life.

    Full Text Available Theatrical art had a significant influence on the formation of social and cultural space of the city at all times. Currently Khabarovsk is one of the theatrical art centres in the Russian Far East. In this regional center theaters of different genres and periods exist. To study the Khabarovsk puppet theater is relevant because of growing interest of viewers of different ages to its activity, as well as the increasing role of the theater in the cultural and social development of the Far Eastern region. The puppet theater was created and later revived in the period of social modernization of the 1920s and 1990s. The paper attempts to identify the causes of the popularization of puppet theaters in certain historical periods. The peculiarities of a puppet genre can be explained by the Russian Far East situation at that time that created the appearance of the city puppeteers in the theatrical space whose work accumulated all the best traditions of Russian and the world puppet genre. Archive documentation analysis allowed creating a holistic view of the puppet theater major directions in the period of radical transformation of the 1990s.

    Full Text Available The article examines “theater” as a cultural and artistic universal that served as a means ofThe article examines “theater” as a cultural and artistic universal that served as a means of developing mindset and self-identity of the Austrian literary group “Young Vienna” at the thth turn of the 19 and 20 centuries. Theater as a metaphor of the human life becomes integral part of the poetics in the works of the group members. The essay examines ideas and fictional worlds of the writers belonging to the group against the context of their contemporary culture. It touches upon Russian perception of the aesthetics of Viennese theater (A. Block, A.J. Tairov and involves retrospective evidences and reflections of Austrian authors (Stefan thth weig, G. Broch on Vienna at the turn of the 19 and 20centuries. As soon as Habsburgs’ empire loses its political positions, the theatrical illusion becomes more and more important. Yet it is the “Young Vienna” that makes the idea of the theater all-pervading: this concept includes both the motif of hopeless masquerade (Schnitzler and the motif of liberation from the false play of masks (Hofmannsthal. According to the concept of the group’s mastermind H. Bahr, the theater played essential role in the spiritual and aesthetic integration of Austria. References to the mystery genre, the street theater, the puppet theater may be traced in the plays written by the members of the group. Austrian authors reconstructed folk plays that enabled the mactualize primordial theatrical forms and inspired them to subtly play with these forms. For the “Young Vienna” group, theater becomes a projection of doubts and misgivings of their time. In place of a jaded actor, there comes a person without a mask who appears at once unprotected and open to acquire his or her “true” face.

    1996-01-01

    This book offers a historical development of our understanding of the fundamental theories of nuclear forces from 1932 to 1950, in order to allow present day researchers a sense of perspective. The book is divided into four parts, which relate to specific periods in the development of nuclear forces theories, and concludes by considering subsequent related developments, with particular regard to the elementary particles. The first sections describes the ideas which lead towards the goal of a unified theory of nuclear forces. Yukawa's Heavy Quantum and the Mesotron are considered in the second part. The third section looks at how the meson theory came to fit among ideas on elementary particles. The fourth section describes the growing understanding of meson physics that took place between 1939 and 1950 and how this understanding led to the discovery of the pion and the development of the Standard Model.

    2016-01-01

    This study aims to explore the views of members of theater teams regarding the proposed introduction of a workplace-based assessment of nontechnical skills of surgeons (NOTSS) into the Intercollegiate Surgical Curriculum Programme in the United Kingdom. In addition, the previous training and familiarity of the members of the surgical theater team with the concept and assessment of NOTSS would be evaluated. A regional survey of members of theater teams (consultant surgeons, anesthetists, scrub nurses, and trainees) was performed at 1 teaching and 2 district general hospitals in South Yorkshire. There were 160 respondents corresponding to a response rate of 81%. The majority (77%) were not aware of the NOTSS assessment tool with only 9% of respondents reporting to have previously used the NOTSS tool and just 3% having received training in NOTSS assessment. Overall, 81% stated that assessing NOTSS was as important as assessing technical skills. Trainees attributed less importance to nontechnical skills than the other groups (p ≤ 0.016). Although opinion appears divided as to whether the presence of a consultant surgeon in theater could potentially make it difficult to assess a trainee's leadership skills and decision-making capabilities, overall 60% agree that the routine use of NOTSS assessment would enhance safety in the operating theater and 80% agree that the NOTSS tool should be introduced to assess the nontechnical skills of trainees in theater. However, a significantly lower proportion of trainees (45%) agreed on the latter compared with the other groups (p = 0.001). Our survey demonstrates acceptability among the theater team for the introduction of the NOTSS tool into the surgical curriculum. However, lack of familiarity highlights the importance of faculty training for assessors before such an introduction. Copyright © 2015 Association of Program Directors in Surgery.

  8. Short-range components of nuclear forces: Experiment versus mythology

    International Nuclear Information System (INIS)

    Kukulin, V. I.; Platonova, M. N.

    2013-01-01

    The present-day situation around the description of various (central, spin-orbit, and tensor) components of short-range nuclear forces is discussed. A traditional picture of these interactions based on the idea of one-meson exchange is contrasted against numerous results of recent experiments. As is shown in the present study, these results often deviate strongly from the predictions of traditional models. One can therefore state that such models are inapplicable to describing short-range nuclear forces and that it is necessary to go over from a traditional description to some alternative QCD-based (or QCD-motivated) picture. This means that, despite the widespread popularity of traditional concepts of short-range nuclear forces and their applicability in many particular cases, these concepts are not more than scientific myths that show their inconsistency when analyzed from the viewpoint of the modern experiment

    Poggio, M; Degen, C L

    2010-08-27

    We review recent efforts to detect small numbers of nuclear spins using magnetic resonance force microscopy. Magnetic resonance force microscopy (MRFM) is a scanning probe technique that relies on the mechanical measurement of the weak magnetic force between a microscopic magnet and the magnetic moments in a sample. Spurred by the recent progress in fabricating ultrasensitive force detectors, MRFM has rapidly improved its capability over the last decade. Today it boasts a spin sensitivity that surpasses conventional, inductive nuclear magnetic resonance detectors by about eight orders of magnitude. In this review we touch on the origins of this technique and focus on its recent application to nanoscale nuclear spin ensembles, in particular on the imaging of nanoscale objects with a three-dimensional (3D) spatial resolution better than 10 nm. We consider the experimental advances driving this work and highlight the underlying physical principles and limitations of the method. Finally, we discuss the challenges that must be met in order to advance the technique towards single nuclear spin sensitivity-and perhaps-to 3D microscopy of molecules with atomic resolution.

    Little is known about the effects of combat exposure on women's health after service in Operation Iraqi Freedom (OIF). Our purpose was to describe the incidence and nature of physical heath symptoms reported by deployed women to identify problematic areas where early intervention or better surveillance might be directed. Using a random, stratified sample (theater vs. non-theater; parent vs. non-parent; and military component including active, guard, and reserve members) of 1,114 Air Force women, we provide descriptive statistics, group comparisons, and multiple regression models to identify health concerns and potential predictors of physical health outcomes. Findings revealed that those in the reserve/guard forces (vs. active duty) and those in the theater of operations (vs. elsewhere during the same time period) reported greater physical health problems (β = -0.07, p social functioning (β = 0.08, p war-related predictors of health among women serving in deployed locations around the world.

    Theoretical and phenomenological approaches to parity-non-conserving nuclear forces are reviewed. Recent developments in the calculation of weak meson-nucleon coupling constants, whose knowledge is necessary to determine theoretically the parity-non-conserving nucleon-nucleon potential, are described. The consistency of different measurements of parity-non-conserving effects is discussed and the information they provide is compared to theoretical predictions

  14. Vocal Qualities in Music Theater Voice: Perceptions of Expert Pedagogues.

    To gather qualitative descriptions of music theater vocal qualities including belt, legit, and mix from expert pedagogues to better define this voice type. This is a prospective, semistructured interview. Twelve expert teachers from United States, United Kingdom, Asia, and Australia were interviewed by Skype and asked to identify characteristics of music theater vocal qualities including vocal production, physiology, esthetics, pitch range, and pedagogical techniques. Responses were compared with published studies on music theater voice. Belt and legit were generally described as distinct sounds with differing physiological and technical requirements. Teachers were concerned that belt should be taught "safely" to minimize vocal health risks. There was consensus between teachers and published research on the physiology of the glottis and vocal tract; however, teachers were not in agreement about breathing techniques. Neither were teachers in agreement about the meaning of "mix." Most participants described belt as heavily weighted, thick folds, thyroarytenoid-dominant, or chest register; however, there was no consensus on an appropriate term. Belt substyles were named and generally categorized by weightedness or tone color. Descriptions of male belt were less clear than for female belt. This survey provides an overview of expert pedagogical perspectives on the characteristics of belt, legit, and mix qualities in the music theater voice. Although teacher responses are generally in agreement with published research, there are still many controversial issues and gaps in knowledge and understanding of this vocal technique. Breathing techniques, vocal range, mix, male belt, and vocal registers require continuing investigation so that we can learn more about efficient and healthy vocal function in music theater singing.

  16. Chiral nucleon-nucleon forces in nuclear structure calculations

    Directory of Open Access Journals (Sweden)

    Coraggio L.

    2016-01-01

    Full Text Available Realistic nuclear potentials, derived within chiral perturbation theory, are a major breakthrough in modern nuclear structure theory, since they provide a direct link between nuclear physics and its underlying theory, namely the QCD. As a matter of fact, chiral potentials are tailored on the low-energy regime of nuclear structure physics, and chiral perturbation theory provides on the same footing two-nucleon forces as well as many-body ones. This feature fits well with modern advances in ab-initio methods and realistic shell-model. Here, we will review recent nuclear structure calculations, based on realistic chiral potentials, for both finite nuclei and infinite nuclear matter.

  17. Jan Fabre: death and rebirth of the theater

    Directory of Open Access Journals (Sweden)

    Roberto Giambrone

    2012-11-01

    Full Text Available Jan Fabre is one of the most controversial European scene figures. His interests range from visual arts to theater and dance. His works, disturbing and provocative, are very contemporary in style and language, while referring to the tradition of Flemish painting. With his performances Fabre demolishes traditional theatre conventions. Theatrical device questioning leads him to disorganize dynamics of representation and to elaborate the concept of crisis until death and apocalypse boundaries. In representing death, Fabre revives theater, according to the principle of metamorphosis. His entire choreography can be defined by balance seeking between opposite poles, good and evil, stasis and movement, beauty and chaos, life and death.

    2013-01-01

    This paper is contributed to the planed title of 'Thirty Years History of The Playing Fields of Physics'. These thirty years are exactly the period while the author has devoted himself to the research and study of physics. The title is centered on the papers on experiments. He wishes, however, to write based on his experience as a theoretical physicist on the nuclear physics as it should be and in which direction to be developed. He would like to dedicate this paper to the late Professors M. Muraoka and K. Sugimoto of Osaka University. In the section 2 of 'Overwhelming Power and Difficulty of π Mesons', the fundamental pictures of '2.1 Start of the Yukawa's π Meson theory', '2.2 Mayer-Jensen's shell model', '2.3 Nambu's chiral symmetry and its spontaneous breaking' are introduced briefly. In the section 3 of 'Physics Lead by the Nuclear Forces Including π Mesons', the subsection '3.1 Phenomenological nuclear force' is taken up at first, then '3.2 Structure of D and tensor forces', '3.3 Structure of triton and three body forces', '3.4 Tensor forces in α-particles' and '3.5 Shell structure of light nuclei developed by the Argonne group' are explained successively. In section 4 of 'Tensor Best Fitting Shell-Model', problems on '4.1 Halo structure of 11 Li brought about by the tensor force' and '4.2 Strong tensor correlated Hartree-Fock theory' are explained. In section 5 of 'Nuclear Structure in the age of K computer', present and future view is given in '5.1 Nuclear forces described on Quantum Chromo Dynamics', '5.2 Present status of the nuclear structure derived on the lattice QCD', '5.3 Three-body forces created by π mesons' and '5.4 Role of K computer in nuclear physics'. In section 6 of 'Fusion of D', a new way to reconsider this problem as one of the nuclear physics is presented. In the final section 7 of 'Exciting Nuclear Physics' a short summary and memories of Professor Sugimoto are given. (S. Funahashi)

  5. Plasma wake and nuclear forces on fragmented H+ transport

    International Nuclear Information System (INIS)

    Barriga-Carrasco, Manuel D; Deutsch, Claude

    2006-01-01

    The objective of the present work is to study the target electronic and nuclear interactions produced when a H + ion traverses classical plasma matter. Electronic interactions are treated by means of the dielectric formalism while nuclear interactions are dealt within the classical dispersion theory through a Monte Carlo computer code. The interactions through plasma electronic medium among close ions are called wake forces. We checked that these forces screen the Coulomb explosions of the two fragmented protons from the same H + ion decreasing their relative distance in the analysed cases. These forces align the interproton vector along the motion direction. They also tend the two-proton energy loss to the value of two isolated protons when at early times it is rather larger. Nevertheless most parts of these wake effects cannot be corroborated experimentally as they are masked by the projectile collisions with target nuclei in our numerical experiment. These collisions cancel the screening produced by the wake forces, increasing the interproton distance even faster than for bare Coulomb explosion. Also they misalign the interproton vector along the motion direction and contribute moderately to increase the energy loss of the fragmented H + ion. These nuclear collisions effects are more significant in reducing projectile velocity

    The expansion of knowledge and technological advances in nuclear medicine and radiology require physicians to have more expertise in functional and anatomic imaging. The convergence of these two specialties into the new discipline of molecular imaging has also begun to place demands on residency training programs for additional instruction in physiology and molecular biology. These changes have unmasked weaknesses in current nuclear medicine and radiology training programs. Adding to the impetus for change are the attendant realities of the job market and uncertain employment prospects for physicians trained in nuclear medicine but not also trained in diagnostic radiology. With this background, the ACR and the Society of Nuclear Medicine convened the Task Force on Nuclear Medicine Training to define the issues and develop recommendations for resident training.

    The properties of exotic nuclei on the verge of existence play a fundamental part in our understanding of nuclear interactions. Exceedingly neutron-rich nuclei become sensitive to new aspects of nuclear forces. Calcium, with its doubly magic isotopes $^{40}$Ca and $^{48}$Ca, is an ideal test for nuclear shell evolution, from the valley of stability to the limits of existence. With a closed proton shell, the calcium isotopes mark the frontier for calculations with three-nucleon forces from chiral effective field theory. Whereas predictions for the masses of $^{51}$Ca and $^{52}$Ca have been validated by direct measurements$^4$, it is an open question as to how nuclear masses evolve for heavier calcium isotopes. Here we report the mass determination of the exotic calcium isotopes $^{53}$Ca and $^{54}$Ca, using the multi-reflection time-of-flight mass spectrometer of ISOLTRAP at CERN. The measured masses unambiguously establish a prominent shell closure at neutron number N = 32, in excellent agreement with our t...

This book analyzes the geo-political situation in this region of the world and asks some important questions about the new strategic map of Asia: what is the impact of the development of nuclear activities on the security of Asia? Will the deployment of anti-missile defenses lead to a new weapons rush? Is there a nuclear warfare risk? (J.S.)

    The attempts to find the right (underlying) theory for the nuclear force have a long and stimulating history. Already in 1953, Hans Bethe stated that “more man-hours have been given to this problem than to any other scientific question in the history of mankind”. In search for the nature of the nuclear force, the idea of sub-nuclear particles was created which, eventually, generated the field of particle physics. I will review this productive history of hope, error, and desperation. Finally, I will discuss recent ideas which apply the concept of an effective field theory to low-energy QCD. There are indications that this concept may provide the right framework to properly understand nuclear forces.

    Full Text Available Current theaters of operations are not limited to battlefields, but they are much morediversified, including the fight against the international terrorism phenomenon, the social conflicts (ofreligious, political, economic and separatist nature within several countries, thus supplying somepolitical-military conflicts within different states and areas of the world. The armed interference mustbe done based on some highly accurate information that must be gathered without endangering thehuman lives. This is the role currently played by the unmanned air vehicles (UAVs; they can performseveral functions: surveillance, information gathering, data storage and their transmission to theground stations, including the function of interference, when needed. This paper presents, within theabove context, the status of the current theaters of operations and of the UAVs performing differentmissions within these theaters, together with their role and importance in warfare operations.

    Theater, music, dance, the literary and the visual arts can convey the joys and controversies of science. We describe a program at the Graduate Center entitled Science & the Arts which is designed to communicate to the public the excitement and wonder of science, technology, engineering and mathematics. Over the past few years there have been major successes in communicating science to the public through the arts. This is especially evident in theater, film and opera with such recent plays as Copenhagen, the Oscar winning film A Beautiful Mind and the opera Doctor Atomic at the Met. The performance series Science & the Arts has been developed and tested at the Graduate Center of the City University of New York (CUNY) in mid-Manhattan for more than nine years, see http://web.gc.cuny.edu/sciart/ . We have established working relationships with actors, playwrights, dancers, choreographers, musicians, composers, artists and scientists who work at the intersection of science and the arts. In this presentation we will illustrate many of our collaborations in theater, dance, music and art. Faculty members, professionals and students from the university, other educational institutions, museums, theaters and government laboratories as well as the public with an interest science and arts programs should find this presentation of particular interest.

    2011-07-22

    Force majeure clauses can be found in any commercial contract. Though more or less clear guidelines for the applicability of force majeure (clauses) exist in the form of international and national law, the applicability and enforceability of force majeure clauses with respect to nuclear incidents or disasters, however, remain ambiguous. Until the Japanese nuclear disaster, no major trade region was affected by any of the historical nuclear incidents. This case-study is based on the events surrounding the Tohoku earthquake, respective tsunami and nuclear incidents, especially at the Daiichi NPP and radiological contamination released there. The applicability and enforceability of force majeure clauses with their wide legal and economical implications are analyzed and evaluated according to the CISG and national domestic Japanese law. It is found that the assertion of force majeure is generally highly fact-specific and circumstance-sensitive. In general, the potential of nuclear disaster as an event triggering the force majeure defence is clearly evident, according to both international and Japanese law. Any claim must, however, be substantiated according to the principles of the different legal regimes under which the contract falls. In consequence, a company located within the evacuated areas will probably be able to successfully assert for majeure, whilst the success of any other claim will depend on the presentation of evidence, such as radiation levels and its effects in hindering performance of contractual obligations.

  19. Origins of the Tactical Nuclear Weapons Modernization Program: 1969-1979

    Science.gov (United States)

    Yaffe, Michael David

    On December 12, 1979, the North Atlantic Treaty Organization decided to deploy new long-range theater nuclear forces, Pershing II and Ground-Launched Cruise Missiles. This marked the first major change in NATO's nuclear stockpile since the adoption of the flexible response strategy in 1967. The decision was controversial inasmuch as the Allies disagreed on the fundamental role of nuclear weapons in this strategy and, thereby, the types and number of weapons required for an effective deterrent posture. Europeans generally preferred long-range weapons capable of striking the Soviet Union and small conventional forces while Americans preferred shorter-range nuclear weapons and a stalwart conventional defense. Thus, the December decision is often described as purely politically motivated, in which the Americans reluctantly acquiesced to a European initiative for long-range weapons, prominently expressed by West German Chancellor Helmut Schmidt in 1977. Recently declassified US government documents reveal, however, that long-range missiles were part of a long-term comprehensive nuclear modernization program conceived in the Pentagon under Defense Secretary James Schlesinger during the period of 1973 through 1975, and presented to skeptical European elites who favored arms control negotiations over costly new deployments. This program was motivated as much by changes in the American national security culture as by an increase in the Soviet military threat to Europe. It was grounded on a clear military rationale: "that a feasible and affordable conventional defense is only possible if NATO has modern nuclear forces" that can effectively hold at risk Warsaw Pact ground and air forces throughout the depth of their employment from the inner-German border to the western military districts of the Soviet Union. When the new US administration in 1977 disagreed with the modernization plan and its rationale, opting instead for more conventional forces, the Allies in a reversal of

    Diabetes treatment involves a demanding self-management regime that is particularly challenging to adolescents. There is a need for qualitative research into the specific contexts in which adolescents attempt to balance self-management demands with the needs and desires of adolescent life. This study investigates the usefulness of image theater, a participatory form of theater using the body as an expressive tool, to articulate these dilemmas in daily life contexts. We performed a qualitative analysis of two image theater workshops with 12- to 18-year-old adolescents living with diabetes. Our results show three areas of application: (a) unraveling the contextual complexity of lived experience, (b) the articulation of implicit understandings and underlying motives, and (c) the playful exploration of new behavior. We conclude that image theater is a promising method, especially with respect to the opportunities of a more contextual and action-oriented understanding of the trade-offs made in self-management provide for diabetes education and counseling.

  5. Spin Modes in Nuclei and Nuclear Forces

    International Nuclear Information System (INIS)

    Suzuki, Toshio; Otsuka, Takaharu

    2011-01-01

    Spin modes in stable and unstable exotic nuclei are studied and important roles of tensor and three-body forces on nuclear structure are discussed. New shell model Hamiltonians, which have proper tensor components, are shown to explain shell evolutions toward drip-lines and spin properties of both stable and exotic nuclei, for example, Gamow-Teller transitions in 12 C and 14 C and an anomalous M1 transition in 17 C. The importance and the necessity of the repulsive monopole corrections in isospin T = 1 channel to the microscopic two-body interactions are pointed out. The corrections are shown to lead to the proper shell evolutions in neutron-rich isotopes. The three-body force, in particular the Fujita-Miyazawa force induced by Δ excitations, is pointed out to be responsible for the repulsive corrections among the valence neutrons. The important roles of the three-body force on the energies and transitions in exotic oxygen and calcium isotopes are demonstrated.

    Somal translocation in long bipolar neurons is regulated by actomyosin contractile forces, yet the precise spatiotemporal sites of force generation are unknown. Here we investigate the force dynamics generated during somal translocation using traction force microscopy. Neurons with a short leading process generated a traction force in the growth cone and counteracting forces in the leading and trailing processes. In contrast, neurons with a long leading process generated a force dipole with opposing traction forces in the proximal leading process during nuclear translocation. Transient accumulation of actin filaments was observed at the dipole center of the two opposing forces, which was abolished by inhibition of myosin II activity. A swelling in the leading process emerged and generated a traction force that pulled the nucleus when nuclear translocation was physically hampered. The traction force in the leading process swelling was uncoupled from somal translocation in neurons expressing a dominant negative mutant of the KASH protein, which disrupts the interaction between cytoskeletal components and the nuclear envelope.

    Creative arts have been increasingly implemented in medical education. This study investigated the use of interactive theater and role play with professional actors in teaching breaking bad news to medical students. The objectives were to explore the contexts, approaches, experiences, and reactions in giving and receiving bad news. Second-year medical students participated in a required educational session that utilized interactive theater which helps students learn about the issues of breaking bad news to a patient with cancer. Following the interactive theater piece, professional actors provided students role play experiences in small groups with breaking bad news. Anonymous evaluation surveys were given out to all second-year medical students at the conclusion of the breaking bad news session. Surveys contained quantitative and qualitative responses. Three years of evaluations were analyzed. A total of 451 (88 %) students completed the evaluations. Comments were thematically analyzed. Ninety-four percent agreed that the theater piece prompted reflection on patient-provider communications, and 89 % agreed that it stimulated discussion on complex issues with breaking bad news. The two most common themes in student comments concerned the importance of realism in the theater piece, and the value of experiencing multiple perspectives. Use of professional actors during the role play exercises enhances the realism and pushed the students out of their own "comfort zones" in ways that may more closely approximate real life clinical situations. Interactive theater can be a potentially powerful tool to teach breaking bad news during medical school.

    Full Text Available To prevent surgical site infection (SSI, the airborne microbial concentration in operating theaters must be reduced. The air quality in operating theaters and nearby areas is also important to healthcare workers. Therefore, this study assessed air quality in the post-operative recovery room, locations surrounding the operating theater area, and operating theaters in a medical center. Temperature, relative humidity (RH, and carbon dioxide (CO2, suspended particulate matter (PM, and bacterial concentrations were monitored weekly over one year. Measurement results reveal clear differences in air quality in different operating theater areas. The post-operative recovery room had significantly higher CO2 and bacterial concentrations than other locations. Bacillus spp., Micrococcus spp., and Staphylococcus spp. bacteria often existed in the operating theater area. Furthermore, Acinetobacter spp. was the main pathogen in the post-operative recovery room (18% and traumatic surgery room (8%. The mixed effect models reveal a strong correlation between number of people in a space and high CO2 concentration after adjusting for sampling locations. In conclusion, air quality in the post-operative recovery room and operating theaters warrants attention, and merits long-term surveillance to protect both surgical patients and healthcare workers.

    Full Text Available The analysis of archival sources, published memories of the corypheus (the leading actors of the Ukrainian theatre Marko Kropivnitskiy, Larisa Staryts’ka-Chernyakhivs’ka, Sofia Tobilevych, materials of the periodical press (the newspapers «Trud», «Zarya», «Kievlianin» allowed to examine the question of the first performance by the Ukrainian Professional Drama Theatre the play «Nazar Stodolya» by Taras Shevchenko in Kyiv in January 1882. The question of what preceded and caused the holding of the first performance in the Ukrainian language by the Ukrainian Professional Drama Theatre in January 1882 in Kyiv was investigated. The importance of this event for the Ukrainian society and the development of the Ukrainian Professional Drama Theatre as a whole was revealed. It is noted that in her memories L.M. Staryts’ka-Cherniakhivs’ka emphasized the value of the performance of Ukrainian Professional Drama Theater in Kyiv for the Ukrainian community. She wrote that the spectators filled the lobby and corridors, faces of all present viewers were burning from ardor and enthusiasm, their eyes were shining, there was a lively noise, the native Ukrainian language rang everywhere in the theater.  She noted that the spectators were dressed in Ukrainian national clothes, there were visible bright suits of Ukrainian women in the theater lodges, many children and parents were dressed in Ukrainian costumes in the theater lodges, there could be heard everywhere the native Ukrainian language in the theater. There was the abundance of the heart everywhere. It is found that the partial lifting of restrictions on the Ukrainian staging plays in 1881, made possible for Kyiviets to see the first performance of the Ukrainian Professional Drama Theatre in the Ukrainian language in 1882. It is found that the very first performance of the play «Nazar Stodolya» by the Ukrainian professional actors’ troupe consolidated the Ukrainian speaking Kyiviets and

    The American Association of Physicists in Medicine (AAPM) and the Society of Nuclear Medicine and Molecular Imaging (SNMMI) recognized the need for a review of the current state of nuclear medicine physics training and the need to explore pathways for improving nuclear medicine physics training opportunities. For these reasons, the two organizations formed a joint AAPM/SNMMI Ad Hoc Task Force on Nuclear Medicine Physics Training. The mission of this task force was to assemble a representative group of stakeholders to: Estimate the demand for board‐certified nuclear medicine physicists in the next 5–10 years,Identify the critical issues related to supplying an adequate number of physicists who have received the appropriate level of training in nuclear medicine physics, andIdentify approaches that may be considered to facilitate the training of nuclear medicine physicists. As a result, a task force was appointed and chaired by an active member of both organizations that included representation from the AAPM, SNMMI, the American Board of Radiology (ABR), the American Board of Science in Nuclear Medicine (ABSNM), and the Commission for the Accreditation of Medical Physics Educational Programs (CAMPEP). The Task Force first met at the AAPM Annual Meeting in Charlotte in July 2012 and has met regularly face‐to‐face, online, and by conference calls. This manuscript reports the findings of the Task Force, as well as recommendations to achieve the stated mission. PACS number: 01.40.G‐ PMID:26699325

    A terrorist attack or sabotage at a nuclear facility could lead result in a great amount of loss of life and social chaos, in addition to serious radiological damage. As threats have been evolved more intelligent, divergent, advanced, the international societies including IAEA encourage for all member states to establish the performance-based regulation using Forceon- Force (FOF) exercise, computer simulation. Consequently, the performance evaluation for physical protection at nuclear facilities should focus on properly reacting to threat scenarios. Physical protection should also include detecting, blocking, delaying, interrupting including the human and technical factors the adversary having malicious intention of the realistic main threat element before he accomplishes the goal based on Design Basis Threat (DBT). After the completion of the FOF evaluation system, KINAC will evaluate, and later strengthen its overall security program in response to changes in the threat environment, technological advancements, and lessons learned. As a result, substantial improvements to a nuclear facility security can be predicted. These improvements will focus on a plant security force, physical barriers, intrusion detection systems, surveillance systems, and access controls. Through the building a Force-on-Force scientific evaluation system, KINAC will establish an efficient physical protection implementation system for nuclear energy facilities.

    Beck, David F.

    The Space Nuclear Thermal Propulsion (SNTP) Program is an initiative within the US Air Force to acquire and validate advanced technologies that could be used to sustain superior capabilities in the area or space nuclear propulsion. The SNTP Program has a specific objective of demonstrating the feasibility of the particle bed reactor (PBR) concept. The term PIPET refers to a project within the SNTP Program responsible for the design, development, construction, and operation of a test reactor facility, including all support systems, that is intended to resolve program technology issues and test goals. A nuclear test facility has been designed that meets SNTP Facility requirements. The design approach taken to meet SNTP requirements has resulted in a nuclear test facility that should encompass a wide range of nuclear thermal propulsion (NTP) test requirements that may be generated within other programs. The SNTP PIPET project is actively working with DOE and NASA to assess this possibility.

    The objective of the present work is to study the target electronic and nuclear interactions produced when a H{sub {sup +}} ion traverses classical plasma matter. Electronic interactions are treated by means of the dielectric formalism while nuclear interactions are dealt within the classical dispersion theory through a Monte Carlo computer code. The interactions through plasma electronic medium among close ions are called wake forces. We checked that these forces screen the Coulomb explosions of the two fragmented protons from the same H{sub {sup +}} ion decreasing their relative distance in the analysed cases. These forces align the interproton vector along the motion direction. They also tend the two-proton energy loss to the value of two isolated protons when at early times it is rather larger. Nevertheless most parts of these wake effects cannot be corroborated experimentally as they are masked by the projectile collisions with target nuclei in our numerical experiment. These collisions cancel the screening produced by the wake forces, increasing the interproton distance even faster than for bare Coulomb explosion. Also they misalign the interproton vector along the motion direction and contribute moderately to increase the energy loss of the fragmented H{sub {sup +}} ion. These nuclear collisions effects are more significant in reducing projectile velocity.

  1. NATO's requirements and policy for LRTNF

    International Nuclear Information System (INIS)

    Davis, L.E.

    1994-01-01

    In a special meeting of Foreign and Defense Ministers, the NATO alliance on 12 December 1979 decided to modernize its long range theater nuclear forces (LRTNF) through the deployment in Europe of 572 Pershing II and ground launched cruise missiles (GLCM). This decision was accompanied by an offer from the US to the U.S.S.R. to negotiate limitations on these LRTNF which would be global, equal, and verifiable. The story of NATO's dual-track decision as well as the INF Treaty is well chronicled. What is missing is a detailed study of the processes within the US government and the NATO alliance by which the LRTNF decisions were made. The role that analysis played, and the lessons that can be drawn for future policies on NATO's theater nuclear forces are discussed

  5. Variational method for infinite nuclear matter with noncentral forces

    International Nuclear Information System (INIS)

    Takano, M.; Yamada, M.

    1998-01-01

    Approximate energy expressions are proposed for infinite zero-temperature nuclear matter by taking into account noncentral forces. They are explicitly expressed as functionals of spin- (isospin-) dependent radial distribution functions, tensor distribution functions and spin-orbit distribution functions, and can be used conveniently in the variational method. A notable feature of these expressions is that they automatically guarantee the necessary conditions on the spin-isospin-dependent structure functions. The Euler-Lagrange equations are derived from these energy expressions and numerically solved for neutron matter and symmetric nuclear matter. The results show that the noncentral forces bring down the total energies too much with too dense saturation densities. Since the main reason for these undesirable results seems to be the long tails of the noncentral distribution functions, an effective theory is proposed by introducing a density-dependent damping function into the noncentral potentials to suppress the long tails of the non-central distribution functions. By adjusting the value of a parameter included in the damping function, we can reproduce the saturation point (both the energy and density) of symmetric nuclear matter with the Hamada-Johnston potential.

    Predictive power in theoretical nuclear physics has been a major concern in the study of nuclear structure and reactions. The Effective Field Theory (EFT) based on chiral expansions provides a model independent hierarchy for many body forces at long distances but their predictive power may be undermined by the regularization scheme dependence induced by the counterterms and encoding the short distances dynamics which seem to dominate the uncertainties. We analyze several examples including zero energy NN scattering or perturbative counterterm-free peripheral scattering where one would expect these methods to work best and unveil relevant systematic discrepancies when a fair comparison to the Granada-2013 NN-database and partial wave analysis (PWA) is undertaken.

    Singing styles in Musical Theater singing might differ in many ways from Western Classical singing. However, vocal tract adjustments are not understood in detail. Vocal tract shapes of a single professional Music Theater female subject were analyzed concerning different aspects of singing styles using dynamic real-time magnetic resonance imaging technology with a frame rate of 8 fps. The different tasks include register differences, belting, and vibrato strategies. Articulatory differences were found between head register, modal register, and belting. Also, some vibrato strategies ("jazzy" vibrato) do involve vocal tract adjustments, whereas others (classical vibrato) do not. Vocal tract shaping might contribute to the establishment of different singing functions in Musical Theater singing. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc.

    Full Text Available Based on archival research, this article presents a succinct history of the street theater movement in China through the 1930s. It examines how complex discourses and competing visions, as well as historical events and practices—in particular the War of Resistance against Japan—both shaped and propelled the movement. The author focuses on theoretical and practical issues that promoters and practitioners of street theater dealt with and reflected on in three succeeding stages. Observing that the street theater movement hastened the formation of a modern national imagination, the author argues that the movement presented a paradigmatic development as it foregrounded the imperative to engage rural China as well as the need for participants to acquire new subject positions.

  9. Can Sweden be forced to manage nuclear waste from other countries?

    International Nuclear Information System (INIS)

    Bergstroem, Ulf; Lindgren, Jonas; Nordfors, Lennart; Hallerby, Christer

    2005-06-01

    This report tries to answer two questions: Can Sweden, through supranational decisions, be forced to dispose of other nations nuclear waste within its own borders? and How can a Swedish stakeholder follow and influence EU-agendas, in particular concerning nuclear waste? Sometimes it has been argued that, through the EU-membership, Sweden could be forced to accept foreign radioactive waste for disposal in Sweden. However, the Swedish Nuclear Technology Act clearly states that license for final disposal spent nuclear fuels can not be given for fuel from another country than Sweden. At the Swedish EU entry it was found that the national legislation were compatible with the EU regulations, and as a consequence waste from foreign nuclear plants can not be disposed of in Sweden, even if the plant is owned by a Swedish company. Other conclusions in the report are: The system for decision making in EU is complex and slow and must be supported by supranational and international organs. The process is complex, but offers many opportunities for following-up and influencing. The risk for anything happening 'over-night' in the radioactive waste question is minimal. The issue of regulating radioactive waste management in a supranational way, i.e. by forcing a country to accept wastes from another country is not on the agenda. The Euratom treaty is interpreted in the way that such decision can not be made. The international discussions about regional repositories build upon voluntary agreements. Scenarios leading to coersive legislation are judged to be politically unrealistic - and needing important changes to be realised

    2003-11-01

    This thesis reports on the study of the acoustic properties of 18 theaters belonging to the Andalusian historical and architectural heritage. These theaters have undergone recent renovations to modernize and equip them appropriately. Coincident with this work, evaluations and qualification assessments with regard to their acoustic properties have been carried out for the individual theaters and for the group as a whole. Data measurements for this purpose consisted of acoustic measurements in situ, both before the renovation and after the renovation. These results have been compared with computer simulations of sound fields. Variables and parameters considered include the following: reverberation time, rapid speech transition index, back-ground noise, definition, clarity, strength, lateral efficiency, interaural cross-correlation coefficient, volume/seat ratio, volume/audience-area ratio. Based on the measurements and analysis, general conclusions are given in regard to the acoustic performance of theaters whose typology and size are comparable to those that were used in this study (between 800 and 8000 cubic meters). It is noted that these properties are comparable to those of the majority of European theaters. The results and conclusions are presented so that they should be of interest to architectural acoustics practitioners and to architects who are involved in the planning of renovation projects for theaters Thesis advisors: Juan J.

  13. Many-body forces in nuclear shell-model

    Rath, P.K.

    1985-01-01

    In the microscopic derivation of the effective Hamiltonian for the nuclear shell model many-body forces between the valence nucleons occur. These many-body forces can be discriminated in ''real'' many-body forces, which can be related to mesonic and internal degrees of freedom of the nucleons, and ''effective'' many-body forces, which arise by the confinement of the nucleonic Hilbert space to the finite-dimension shell-model space. In the present thesis the influences of such three-body forces on the spectra of sd-shell nuclei are studied. For this the two common techniques for shell-model calculations (Oak Ridge-Rochester and Glasgow representation) are extended in such way that a general three-body term in the Hamiltonian can be regarded. The studies show that the repulsive contributions of the considered three-nucleon forces become more important with increasing number of valence nucleons. By this the particle-number dependence of empirical two-nucleon forces can be qualitatively explained. A special kind of effective many-body force occurs in the folded diagram expansion of the energy-dependent effective Hamiltonian for the shell model. Thereby it is shown that the contributions of the folded diagrams with three nucleons are just as important as those with two nucleons. Thus it is to be suspected that the folded diagram expansion contains many-particle terms with arbitrary particle number. The present studies however show that four nucleon effects are neglegible so that the folded diagram expansion can be confined to two- and three-particle terms. In shell-model calculations which extend over several main shells the influences of the spurious center-of-mass motion must be regarded. A procedure is discussed by which these spurious degrees of freedom can be exactly separated. (orig.) [de

    High-performance computing is now enabling the calculation of certain hadronic interaction parameters directly from Quantum Chromodynamics, the quantum field theory that governs the behavior of quarks and gluons and is ultimately responsible for the nuclear strong force. In this paper we briefly describe the state of the field and show how other aspects of hadronic interactions will be ascertained in the near future. We give estimates of computational requirements needed to obtain these goals, and outline a procedure for incorporating these results into the broader nuclear physics community.

    In 1981, the Director of the Office of Nuclear Reactor Regulation (NRR) of the Nuclear Regulatory Commission (NRC) chartered a task force to assess the office program of technical assistance and to recommend improvements. The task force divided the technical assistance program into four areas, and the practices in each area were assessed through a series of surveys of staff, management, and contractor personnel. The task force placed emphasis in its interview and assessment process on the problem areas that exist in the technical assistance program. The report thus reflects a weight on the faults found as a result of the inquiries made. The four major areas of technical assistance contracting studied were program planning, program management and execution, program control and management information systems, and program administration and coordination

    A country which decides to develop a militarily significant nuclear force after conducting an acknowledged test of a nuclear explosive device must progress up a series of costs. This chapter examines cases in which the economic costs of moving from one force level to the next are sufficient to limit the rate of growth of capability. It finds that when economic barriers are severe, there seems to be some economic strategies for managing in terms of limiting force improvement through the manipulation of economic factors. These economic levers sometimes go against the grain of traditional politico-military approaches. In all cases, it is necessary to consider whether the overall and long-term effects of the levers applied to a specific country strengthen or weaken the overall strategy, which is to limit and restrain the proliferation of nuclear weapons in general and not just in specific cases. 16 references, 5 figures, 3 tables

    Full Text Available Strategic marketing instruments such as segmentation and targeting can benefit performing arts institutions and render their offer more competitive. To segment classical performing arts audiences, however, the traditionally used variable is social class. In this paper, it is argued that such often suggested traditional segmentation criteria can prove to be context-insensitive and as such cannot be applied invariably across different settings. Based on an analysis of Czech National Theater audiences and its motivations, we propose the sought benefit of the theater visit as an alternative segmentation basis that may prove to be more context-sensitive.

    There are 431 commercial nuclear power plants around the world. On 14 April 2015, 193 of these power plants were covered by a nuclear liability instrument (118 power plants by the Paris Convention and 75 by the Vienna Convention). With the entry into force of the Convention on Supplementary Compensation for Nuclear Damage (CSC)4 on 15 April 2015, the number of power plants covered by a nuclear liability instrument increased to 340. Thus, the entry into force of the CSC marked a major milestone towards the establishment of a global nuclear liability regime. This article discusses several events that have promoted progress towards a global nuclear liability regime and then addresses several questions that may arise as countries consider actions necessary to achieve such a regime.

  8. Condensins Exert Force on Chromatin-Nuclear Envelope Tethers to Mediate Nucleoplasmic Reticulum Formation in Drosophila melanogaster

    Although the nuclear envelope is known primarily for its role as a boundary between the nucleus and cytoplasm in eukaryotes, it plays a vital and dynamic role in many cellular processes. Studies of nuclear structure have revealed tissue-specific changes in nuclear envelope architecture, suggesting that its three-dimensional structure contributes to its functionality. Despite the importance of the nuclear envelope, the factors that regulate and maintain nuclear envelope shape remain largely unexplored. The nuclear envelope makes extensive and dynamic interactions with the underlying chromatin. Given this inexorable link between chromatin and the nuclear envelope, it is possible that local and global chromatin organization reciprocally impact nuclear envelope form and function. In this study, we use Drosophila salivary glands to show that the three-dimensional structure of the nuclear envelope can be altered with condensin II-mediated chromatin condensation. Both naturally occurring and engineered chromatin-envelope interactions are sufficient to allow chromatin compaction forces to drive distortions of the nuclear envelope. Weakening of the nuclear lamina further enhanced envelope remodeling, suggesting that envelope structure is capable of counterbalancing chromatin compaction forces. Our experiments reveal that the nucleoplasmic reticulum is born of the nuclear envelope and remains dynamic in that they can be reabsorbed into the nuclear envelope. We propose a model where inner nuclear envelope-chromatin tethers allow interphase chromosome movements to change nuclear envelope morphology. Therefore, interphase chromatin compaction may be a normal mechanism that reorganizes nuclear architecture, while under pathological conditions, such as laminopathies, compaction forces may contribute to defects in nuclear morphology.

  10. Russia's Nuclear Forces: Between Disarmament and Modernization

    International Nuclear Information System (INIS)

    2011-01-01

    Nuclear weapons have traditionally occupied an important place in Russia's national security strategy. This tradition goes back to the Soviet times, when the country invested considerable efforts into building its nuclear arsenal and achieving strategic parity with the United States. As Russia and the United States have been reducing their nuclear arsenals since the end of the Cold War, their relationship has undergone a complex transformation toward cooperation and partnership mixed with suspicion and rivalry. The focus of Russia's nuclear policy, however, has remained essentially unchanged - it still considers strategic balance with the United States to be an important element of national security and pays considerable attention to maintaining the deterrent potential of its strategic forces. Russia does recognize the emergence of new threats - it cannot ignore the threats related to regional instabilities and conflicts on its own territory and in bordering states, such as the tensions in the Caucasus or the war in Afghanistan, the terrorist activity that is associated with these conflicts, as well as the problems that stem from nuclear and missile proliferation. These, however, are not given a high priority in Russia's security policy. For example, the new military doctrine adopted in February 2010, opens the list of military threats with the expansion of geographical and political reach of NATO, which is followed by the threat to strategic stability and then by deployment of missile defense. Nuclear proliferation, terrorism, and destabilizing local conflicts are placed much further down the list. Even when it comes to confronting the issues of local instabilities and terrorism, Russia's leadership tends to see these issues through the prism of its strategic strength, alleging that terrorist attacks are a reaction to Russia's perceived weakness. This way of looking at the issues effectively redefines national security problems to conform to the traditional view

    The creative process is fun, complex, and sometimes frustrating, but it is critical to the future of our nation and progress in science, technology, engineering, mathematics (STEM), as well as other fields. Thus, we set out to see if implementing methods of active learning typical to the theater department could impact the creativity of senior capstone design students in the bioengineering (BE) department. Senior bioengineering capstone design students were allowed to self-select into groups. Prior to the beginning of coursework, all students completed a validated survey measuring engineering design self-efficacy. The control and experimental groups both received standard instruction, but in addition the experimental group received 1 h per week of creativity training developed by a theater professor. Following the semester, the students again completed the self-efficacy survey. The surveys were examined to identify differences in the initial and final self-efficacy in the experimental and control groups over the course of the semester. An analysis of variance was used to compare the experimental and control groups with p engineering design following the semester of creativity instruction. The results of this pilot study indicate that there is a significant potential to improve engineering students' creative self-efficacy through the implementation of a "curriculum of creativity" which is developed using theater methods.

    Full Text Available From 1948 to 2007, the academic community produced about a hundred titles of theses and dissertations on drama and theater, or made use of data from drama and theater for larger spheres of studies. The current article looked into identifying trends and points of emphasis, as the researches and studies progressed through roughly half a century of research production in the academic setting. Inductive in approach and tentative and exploratory in its analysis, the study identified four trends and points of emphasis in research production. In the fifties and sixties, the emphasis was more on studying the play text or drama; studies veered towards a literary reading and orientation. Eventually, this trend gave way to studying the larger phenomenon of mounting, and the mise en scéne and the spectator became additional units of concern for research. Studies began to have sections on props, costumes, and staging techniques. In the eighties, a larger concern for looking at theater as social production followed. Participant observation, field work and ethnography gave equal emphasis on the social context of theater. Marxism and other perspectives from the social sciences framed theater studies then; correlations between theater and society became useful. Towards the last decade of the century, theater studies aimed at a more conceptual approach, emphasizing core concepts like panata and other related or equivalent terms, elevating and defining the study of theater as a study of culture itself.

    Influenza is an acute respiratory infectious disease with a high incidence rate in the Chinese army, which directly disturbs military training and affects soldiers' health. Influenza surveillance systems are widely used around the world and play an important role in influenza epidemic prevention and control. As a theater centers for disease prevention and control, we established an influenza monitoring platform (IMP) in 2014 to strengthen the monitoring of influenza-like illness and influenza virus infection. In this study, we introduced the constitution, influenza virus detection, and quality control for an IMP. The monitoring effect was also evaluated by comparing the monitoring data with data from national influenza surveillance systems. The experiences and problems associated with the platform also were summarized. A theater IMP was established based on 3 levels of medical units, including monitoring sites, testing laboratories and a checking laboratory. A series of measures were taken to guarantee the quality of monitoring, such as technical training, a unified process, sufficient supervision and timely communication. The platform has run smoothly for 3 monitoring years to date. In the 2014-2015 and 2016-2017 monitoring years, sample amount coincided with that obtained from the National Influenza Surveillance program. In the 2015-2016 monitoring year, due to the strict prevention and control measures, an influenza epidemic peak was avoided in monitoring units, and the monitoring data did not coincide with that of the National Influenza Surveillance program. Several problems, including insufficient attention, unreasonable administrative intervention or subordination relationships, and the necessity of detection in monitoring sites were still observed. A theater IMP was established rationally and played a deserved role in the prevention and control of influenza. However, several problems remain to be solved.

    Birds in the infraorder Corvida [1] (ravens, jays, bowerbirds) are renowned for their cognitive abilities [2-4], which include advanced problem solving with spatial inference [4-8], tool use and complex constructions [7-10], and bowerbird cognitive ability is associated with mating success [11]. Great bowerbird males construct bowers with a long avenue from within which females view the male displaying over his bower court [10]. This predictable audience viewpoint is a prerequisite for forced (altered) visual perspective [12-14]. Males make courts with gray and white objects that increase in size with distance from the avenue entrance. This gradient creates forced visual perspective for the audience; court object visual angles subtended on the female viewer's eye are more uniform than if the objects were placed at random. Forced perspective can yield false perception of size and distance [12, 15]. After experimental reversal of their size-distance gradient, males recovered their gradients within 3 days, and there was little difference from the original after 2 wks. Variation among males in their forced-perspective quality as seen by their female audience indicates that visual perspective is available for use in mate choice, perhaps as an indicator of cognitive ability. Regardless of function, the creation and maintenance of forced visual perspective is clearly important to great bowerbirds and suggests the possibility of a previously unknown dimension of bird cognition.

    2012-03-01

    Along with the success of the digitally revived stereoscopic cinema, events beyond 3D movies become attractive for movie theater operators, i.e. interactive 3D games. In this paper, we present a case that explores possible challenges and solutions for interactive 3D games to be played by a movie theater audience. We analyze the setting and showcase current issues related to lighting and interaction. Our second focus is to provide gameplay mechanics that make special use of stereoscopy, especially depth-based game design. Based on these results, we present YouDash3D, a game prototype that explores public stereoscopic gameplay in a reduced kiosk setup. It features live 3D HD video stream of a professional stereo camera rig rendered in a real-time game scene. We use the effect to place the stereoscopic effigies of players into the digital game. The game showcases how stereoscopic vision can provide for a novel depth-based game mechanic. Projected trigger zones and distributed clusters of the audience video allow for easy adaptation to larger audiences and 3D movie theater gaming.

    Highlights: • A probabilistic model on long-term degradation of tendon force is developed. • By using the model, we performed reliability evaluation of nuclear containment. • The analysis is also performed for the case with the strict maintenance programme. • We showed how to satisfy the target safety in the containments facing life extension. - Abstract: The long-term reliability of nuclear containment is important for operating nuclear power plants. In particular, long-term reliability should be clarified when the service life of nuclear containment is being extended. This study focuses not only on determining the reliability of nuclear containment but also presenting the reliability improvement by strengthening the containment itself or by running a strict maintenance programme. The degradation characteristics of tendon force are estimated from the data recorded during in-service inspection of containments. A reliability analysis is conducted for a limit state of through-wall cracking, which is conservative, but most crucial limit state. The results of this analysis indicate that reliability is the lowest at 3/4 height of the containment wall. Therefore, this location is the most vulnerable for the specific limit state considered in this analysis. Furthermore, changes in structural reliability owing to an increase in the number of inspecting tendons are analysed for verifying the effect of the maintenance program's intensity on expected containment reliability. In the last part of this study, an example of obtaining target reliability of nuclear containment by strengthening its structural resistance is presented. A case study is conducted for exemplifying the effect of strengthening work on containment reliability, especially during extended service life

    The importance of maintaining performance of a hospital operating theater is to establish an adequate circulation of clean air within the room. The parameter of air distribution in a space should be based on Air Changes per Hour (ACH) to maintain a positive room pressure. The dispersion of airborne particles in the operating theater was governed by regulating the air distribution so that the operating theater meets clean room standards ie ISO 14664 and ASHRAE 170. Here, we introduced several input parameters in a simulation environment to observe the pressure distribution in the room. Input parameters were air temperature, air velocity and volumetric flow rate entering and leaving room for existing and designed condition. In the existing operating theatre, several observations were found. It was found that the outlet air velocity at the HEPA filter above the operating table was too high thus causing a turbulent airflow pattern. Moreover, the setting temperature at 19°C was found to be too low. The supply of air into the room was observed at lower than 20 ACH which is under the standard requirement. Our simulation using FloVent 8.2™ program showed that not only airflow turbulence could be reduced but also the amount of particle contamination could also be minimized.

Nuclear force is in principle the manifestation of dynamics of quarks and gluons but no trial has been successful yet in describing the nuclear force by using QCD, the fundamental theory of the strong interactions. Phenomenon related to the chiral symmetry and the spontaneous breaking of the chiral symmetry is one of the important phenomena for the understanding of hadron physics. Nambu-Jona-Lasinio (NJL) model is one of the quark system models to explain the phenomena concerning the chiral symmetry. Although the method to deduce the Lagrangian describing mesons by applying the path integral to NJL model has been well known as the bosonization, it has been difficult to extend it to baryons because baryons are three-body system. In this paper, a method is reported to deduce Lagrangian which describes baryon-meson from quark-diquark Lagrangian by assuming that baryons are the bound states of quark and diquark. (S. Funahashi)

    The finite temperature Brueckner-Hartree-Fock (FTBHF) approach is extended by introducing a microscopic three-body force. Within the extended approach, the three-body force effects on the equation of state of hot nuclear matter and its temperature dependence have been investigated. The critical properties of the liquid-gas phase transition of hot nuclear matter have been calculated. It is shown that the three-body force provides a repulsive contribution to the equation of state of hot nuclear matter. The repulsive effect of the three-body force becomes more pronounced as the density and temperature increase and consequently inclusion of the three-body force contribution in the calculation reduces the predicted critical temperature from about 16 MeV to about 13 MeV. By separating the contribution originated from the 2σ-exchange process coupled to the virtual excitation of a nucleon-antinucleon pair from the full three-body force, the connection between the three-body force effect and the relativistic correction from the Dirac-Brueckner-Hartree-Fock has been explored. It turns out that the contribution of the 2σ-N(N-bar) part is more repulsive than that of the full three-body force and the calculated critical temperature is about 11 MeV if only the 2σ-N(N-bar) component of the three-body force is included which is lower than the value obtained in the case of including the full three-body force and is close to the value predicted by the Dirac-Brueckner-Hartree-Fock (DBHF) approach. Our result provides a reasonable explanation for the discrepancy between the values of critical temperature predicted from the FTBHF approach including the three-body force and the DBHF approach.

    A simple prescription for estimating the energy at which nuclear forces begin to play a role in heavy-ion Coulomb excitation and Coulomb fission experiments is presented. The method differs from most commonly used recipes in accounting for projectile and target nucleus deformation effects. Using a single adjustable parameter the formula reproduces the energy for the onset of Coulomb-nuclear interference effects for a broad range of heavy-ion systems. It is suggested that most Coulomb fission experiments which have been done involve both Coulomb and nuclear excitation processes and should more properly be termed Coulomb-nuclear fission experiments

    Since 9 March 2006 the United Nations Security Council has been examining the report on Iran by the IAEA, which noted the failure of years of negotiations between Iran and the EU3 nations representing Europe (Britain, France and Germany). Following the June 2005 election of Mr Ahmadinejad, relations with the international community have become notably tense, with the resumption of nuclear activity (reprocessing, enrichment, etc.). The West is now convinced that this civil programme is enabling Iran to conceal a military programme, which, if it is completed, will shatter relationships, political and economic, in an area of strategic importance. The tensions generated by the policy adopted by Iran, in its forced march towards a nuclear capability, brings to the fore the nuclear proliferation problem, which is likely to become one of the major threats of the twenty-first century.

    INtraoperative Video Enhanced Surgical procedure Training (INVEST) is a new training method designed to improve the transition from basic skills training in a skills lab to procedural training in the operating theater. Traditionally, the master-apprentice model (MAM) is used for procedural training in the operating theater, but this model lacks uniformity and efficiency at the beginning of the learning curve. This study was designed to investigate the effectiveness and efficiency of INVEST compared to MAM. Ten surgical residents with no laparoscopic experience were recruited for a laparoscopic cholecystectomy training curriculum either by the MAM or with INVEST. After a uniform course in basic laparoscopic skills, each trainee performed six cholecystectomies that were digitally recorded. For 14 steps of the procedure, an observer who was blinded for the type of training determined whether the step was performed entirely by the trainee (2 points), partially by the trainee (1 point), or by the supervisor (0 points). Time measurements revealed the total procedure time and the amount of effective procedure time during which the trainee acted as the operating surgeon. Results were compared between both groups. Trainees in the INVEST group were awarded statistically significant more points (115.8 vs. 70.2; p < 0.001) and performed more steps without the interference of the supervisor (46.6 vs. 18.8; p < 0.001). Total procedure time was not lengthened by INVEST, and the part performed by trainees was significantly larger (69.9 vs. 54.1 %; p = 0.004). INVEST enhances effectiveness and training efficiency for procedural training inside the operating theater without compromising operating theater time efficiency.

  3. A common body of care: the ethics and politics of teamwork in the operating theater are inseparable.

    In the operating theater, the micro-politics of practice, such as interpersonal communications, are central to patient safety and are intimately tied with values as well as knowledge and skills. Team communication is a shared and distributed work activity. In an era of "professionalism," that must now encompass "interprofessionalism," a virtue ethics framework is often invoked to inform practice choices, with reference to phronesis or practical wisdom. However, such a framework is typically cast in individualistic terms as a character trait, rather than in terms of a distributed quality that may be constituted through intentionally collaborative practice, or is an emerging property of a complex, adaptive system. A virtue ethics approach is a necessary but not sufficient condition for a collaborative bioethics within the operating theater. There is also an ecological imperative-the patient's entry into the household (oikos) of the operating theater invokes the need for "hospitality" as a form of ethical practice.

  5. The Coulomb-nuclear force interference in the system 32S + 60Ni

    1980-01-01

    For the reaction 60 Ni( 32 S, 32 S*) 60 Ni* using particle-γ-coincidences the excitation functions of 32 S(2 + 1 ) and 60 Ni(2 + 1 ) for projectile energies of 70-100 MeV as well as with Si single counters the angular distribution of the elastically and inelastically scattered 32 S ions for incident energies of 90, 95, and 100 MeV were measured. A comparison of the measurements with the results of different computer codes led to following results: 1.) At the determination of the static quadrupole moment Q 2 of 32 S using the reorientation effect the influence of the nuclear force can be neglected for projectile energies Esub(P) 32 S the value Q 2 = -0.18 +- 0.04 eb was found. (Hereby destructive interference with the virtual excitation of the 2 + 2 -state is assumed). 3.) For projectile energies Esub(P) >= 72 MeV at which the excitation by nuclear forces was small against the Coulomb excitation, an evaluation of the excitation function of 32 S(2 + 1 ) by the semiclassical code NCL, which regards the influence of the nuclear interaction approximatively, yielded values for the static quadrupole moment, which agree within the measurement errors with the above value. 4.) For the quantitative analysis of the measured angular distributions a quantum mechanical CC-code was required. 5.) Using the semiclassical CC-code NCL an illustrative and detailed interpretation of the excitation functions of 32 S(2 + 1 ) and 60 Ni(2 + 1 ) could be given. 6.) The code NCL allows the study of the influence of the Coulomb-nuclear force interference on the temporal behaviour of the excitation process. 7.) Using the code NCL the angular distribution of the decay γ quanta for a fixed particle-scattering angle theta approx. 0 in dependence on the incident energy was calculated. (orig.) [de

    2018-02-01

    The spin-dependent nature of the nuclear tensor force is studied in detail within the relativistic Hartree-Fock approach. The relativistic formalism for the tensor force is supplemented with an additional Lorentz-invariant tensor formalism in the σ-scalar channel, so as to take into account almost fully the nature of the tensor force brought about by the Fock diagrams in realistic nuclei. Specifically, the tensor sum rules are tested for the spin and pseudo-spin partners with and without nodes, to further understand the nature of the tensor force within the relativistic model. It is shown that the interference between the two components of nucleon spinors causes distinct violations of the tensor sum rules in realistic nuclei, mainly due to the opposite signs on the κ quantities of the upper and lower components, as well as the nodal difference. However, the sum rules can be precisely reproduced if the same radial wave functions are taken for the spin/pseudo-spin partners in addition to neglecting the lower/upper components, revealing clearly the nature of the tensor force.

    2014-01-01

    In this paper, the role of three-nucleon forces in ab initio calculations of nuclear systems is investigated. The difference between genuine and induced many-nucleon forces is emphasized. Induced forces arise in the process of solving the nuclear many-body problem as technical intermediaries toward calculationally converged results. Genuine forces make up the Hamiltonian. They represent the chosen underlying dynamics. The hierarchy of contributions arising from genuine two-, three- and many-nucleon forces is discussed. Signals for the need of the inclusion of genuine three-nucleon forces are studied in nuclear systems, technically best under control, especially in three-nucleon and four-nucleon systems. Genuine three-nucleon forces are important for details in the description of some observables. Their contributions to observables are small on the scale set by two-nucleon forces. (author)

  15. Russia's Nuclear Forces: Between Disarmament and Modernization

    Energy Technology Data Exchange (ETDEWEB)

    Nuclear weapons have traditionally occupied an important place in Russia's national security strategy. This tradition goes back to the Soviet times, when the country invested considerable efforts into building its nuclear arsenal and achieving strategic parity with the United States. As Russia and the United States have been reducing their nuclear arsenals since the end of the Cold War, their relationship has undergone a complex transformation toward cooperation and partnership mixed with suspicion and rivalry. The focus of Russia's nuclear policy, however, has remained essentially unchanged - it still considers strategic balance with the United States to be an important element of national security and pays considerable attention to maintaining the deterrent potential of its strategic forces. Russia does recognize the emergence of new threats - it cannot ignore the threats related to regional instabilities and conflicts on its own territory and in bordering states, such as the tensions in the Caucasus or the war in Afghanistan, the terrorist activity that is associated with these conflicts, as well as the problems that stem from nuclear and missile proliferation. These, however, are not given a high priority in Russia's security policy. For example, the new military doctrine adopted in February 2010, opens the list of military threats with the expansion of geographical and political reach of NATO, which is followed by the threat to strategic stability and then by deployment of missile defense. Nuclear proliferation, terrorism, and destabilizing local conflicts are placed much further down the list. Even when it comes to confronting the issues of local instabilities and terrorism, Russia's leadership tends to see these issues through the prism of its strategic strength, alleging that terrorist attacks are a reaction to Russia's perceived weakness. This way of looking at the issues effectively redefines national security problems to conform

    Bonded tendons have been used in reactor buildings of heavy water reactors and the light water reactors of some nuclear power plants operating in Korea. The assessment of prestressed forces on those bonded tendons is becoming an important issue in assuring their continuous operation beyond their design life. In order to assess the effective prestressed force on the bonded tendon, indirect assessment techniques have been applying to the test beams which were manufactured on construction time. Therefore, this research mainly forced to establish the assessment methodology to measure directly the effective prestressed force on the bonded tendon of containment buildings using System Identification (SI) technique. To accomplish this purpose, simple SI method was proposed and adapted three dimensional finite element analysis of the 1:4 scale prestressed concrete containment vessel (PCCV) tested by Sandia National Laboratory in 2000

    In the phenomenological description of the nuclear interaction an important role is traditionally played by the exchange of a scalar I=0 meson, the sigma, of mass 500-600 MeV, which however is not seen clearly in the particle spectrum and which has a very ambiguous status in QCD. I show that a remarkably simple and reasonably controlled combination of ingredients can reproduce the features of this part of the nuclear force. The use of chiral perturbation theory calculations for two pion exchange supplemented by the Omnes function for pion rescattering suffices to reproduce the magnitude and shape of the exchange of a supposed σ particle. I also attempt to relate this description to the contact interaction that enters more modern descriptions of the internucleon interaction

    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a very important treaty, not only for Japan but also for the world, because it prohibits any nuclear weapon test explosion or any other nuclear explosion anywhere in the world. The treaty however will not enter into force until it has been signed and ratified by all the 44 states listed in Annex 2 to the treaty. Many efforts to facilitate the treaty's early entry into force are being done by many countries and many international organizations. As one of result of these efforts, a Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization had be established at a meeting of State Signatories on 19 November 1996, and the Commission started activities to establish global verification regime of the treaty and to prepare for its entry into force. Under the CTBT activities, the Japan Atomic Energy Research Institute (JAERI) is expected to play an important role as supporter for the Japanese Government, especially in a field of an International Monitoring System (IMS). However, there is no appropriate guide book on the CTBT for JAERI staff at present. This report provides some introduction of the CTBT regime and preparatory activities for its entry into force. Only open source information is used for making the report. If anyone need more detail information, it should be asked to contact competent authorities. (author)

    Full Text Available Theaterplakate gehören zur Tätigkeit des Theaters. Anfangs erfüllten sie eine reine Gebrauchsfunktion, indem sie über ein kulturelles Ereignis informierten, das an einem bestimmten Tag, zu einer bestimmten Uhrzeit, an einem bestimmten Ort stattfinden wird. Mit der Zeit bekamen sie jedoch die Eigenschaften eines Zeugens aus der Vergangenheit, indem sie die Geschichte ihres Urhebers zeigten, das Profil seiner Tätigkeit, die in seiner Struktur vor sich gehenden Veränderungen. Die Wurzeln der Theaterplakate sind schon in der Antike zu suchen, sie wurden von Ägyptern, Römern und Griechen geschaffen. Das älteste neuzeitliche Plakat erschien 1429 in London und ist heute ein Exponat im Londoner Theatermuseum. Die Geschichte der polnischen Plakate reicht bis ins 16. oder 17. Jahrhundert zurück, hier sind sich die Forscher nicht einig, und ist entweder mit einem Jesuitenkollegium oder mit dem königlichen Theater verbunden. Die im Text analysierten Thorner Plakate stammen aus den Jahren 1922-1975 und werden in den Sammlungen der Kopernikus-Bücherei und in den Beständen des Staatsarchivs in Thorn aufbewahrt. Geschaffen wurden sie vom Theater in Thorn. Heute ist es das Wilam-Horzyca-Theater, doch sein Name, sein Tätigkeitsfeld, seine Organisationsstruktur und auch sein Profil und die Art seiner Tätigkeit änderten sich im Laufe der besprochenen Jahre vielmals. Die Plakate wurden in chronologischer Ordnung mit einer Aufteilung in Gruppen besprochen. Die Autorinnen beachteten den Inhalt, seine Anordnung und die Form der Aufzeichnung, das Format der Plakate, ihre Farbgebung, Ornamentik und die verwendete Ikonographie. Jede Gruppe wurde detailliert besprochen und illustriert. Nicht allein das Theater in Thorn schuf in der Stadt Theaterplakate. Eine ähnliche aktenkundliche Analyse lässt sich in Bezug auf das Puppentheater „Baj Pomorski” durchführen, doch ist das schon Material für einen gesonderten Artikel.

    Full Text Available Dance, music, and oral narratives are an important and vibrant part of cultural practice and heritage in Timor-Leste. But while Timorese people have used such creative methods and processes during rituals, celebrations, and their fight for independence, today arts and artistic expression become an increasingly popular strategy in development cooperation. Especially diff erent forms of so-called participatory theater with origins in development cooperation, arts, and social movements, present themselves as innovative, participatory, and well applicable in terms of capacity building and stimulating positive social transformation. Based on the author’s experience and observations, this article critically examines the alliance between various stakeholders in Timor-Leste engaging with the fact that the current scene of participatory theater can hardly be seen as an independent grassroots or even social movement, rather than an initiated top-down process by donors with specific agendas.

    Combat injuries are more often associated with blast, penetrating, and high-energy mechanisms than civilian trauma, generating controversy about the management of combat colonic injury. Despite implementation of mandatory colostomy in World War II, recent civilian data suggest that primary repair without diversion is safe and feasible. This study describes the modern management of battle-related colonic injuries and seeks to determine whether management strategy affects early complications. Records from the combat theater (downrange) and tertiary referral center in Germany were retrospectively reviewed from 2005 to 2006. Patient characteristics, management strategy, treatment course, and early complications were recorded. Comparison groups by management strategy were as follows: primary repair, diversion, and damage control. A total of 133 (97% male) patients sustained colonic injuries from penetrating (71%), blunt (5%), and blast (23%) mechanisms. Average injury severity score was 21 and length of stay in the referral center was 7.1 days. Injury distribution was 21% ascending, 21% descending, 15% transverse, 27% sigmoid, and 25% rectum. Downrange complications for primary repair, initial ostomy, and damage control groups were 14%, 15%, and 30%, respectively. On discharge from the center, 62% of patients had undergone a diversion. The complication rate was 18% overall and was unrelated to management strategy (P = .16). Multivariate analysis did not identify independent predictors of complications. Early complications were similar by mechanism, anatomic location, severity of injury, and management strategy. More diversions were performed for rectosigmoid injury. Good surgical judgment allows for low morbidity and supports primary repair in selected cases. Damage control surgery is effective in a multinational theater of operations.

  6. Forced cooling of a nuclear waste repository mine drift - a scoping analysis

    Energy Technology Data Exchange (ETDEWEB)

    1982-12-01

    Nuclear waste repositories, with decay heat generation beneath the mine drift floors, are force-cooled with air so that re-entrance is possible many years after the waste has been buried. A numerical model has been developed which uses heat transfer coefficients as input. It has been demonstrated that mixed (forced and free) convective and surface roughness effects are significant and must be included in future experiments if reliable predictions are to be made of the time required to cool the repository. For example, when repository mine drifts in volcanic tuff are force-cooled, with forced convection being the only energy transport mechanism, it takes approx.= 0.1 year to cool the mine surface to a safe temperature. However, when mixed convection is the primary transport mechanism it takes approx.= 1.0 year to cool the mine. In addition to mixed convection, other effects are delineated.

    The possibility of constructing such new versions of effective nucleon-nucleon forces that would make it possible to describe simultaneously the cross sections for nucleon-nucleus scattering and quantities characterizing nuclear matter and the structure of finite even-even nuclei is investigated on the basis of a microscopic nucleon-nucleus optical potential that is calculated by using effective Skyrme interaction. A procedure for optimizing the parameters of Skyrme forces by employing fits to specific angular distributions for neutron-nucleus scattering and by simultaneously testing the features of nuclear matter, the binding energy of the target nucleus, and its proton root-mean-square radius is proposed. A number of versions of modified Skyrme forces that ensure a reasonable description of both nucleon-nucleus scattering and the properties of nuclear structure are found on the basis of this procedure.

    2017-04-01

    Full Text Available We describe a teaching strategy, namely, the Great Theater of Physics, which stages a series of eight nontrivial demonstrations in the areas of mechanics, electricity, magnetism and waves. The aim was to generate feelings and attitudes that would promote the learning of physics, and to explore the motivation of Chemistry and Biology students towards classes in physics. The strategy was applied with a group of new students in Physics and Mathematics at the Faculty of Sciences at the Universidad Central de Venezuela. The method used was exploratory-descriptive.  Information was collected using a questionnaire with closed questions. In general, students from Physics and Mathematics disciplines experienced a significant increase in positive feelings towards physics after attending the theater; and negative feelings decreased, though not significantly. A greater percentage of women than men experienced an increase in positive feelings, though men experienced more intense positive feelings. This was not the case for negative feelings.

    Every year, millions of Americans visit planetariums and are captivated by their strikingly realistic portrayal of the night sky. Today, it is indeed difficult to imagine astronomy education without these magnificent celestial theaters. But projection planetariums, first developed in Germany, have been a part of American museum pedagogy only since the early twentieth century and were not widespread until the 1960s. In this unique social history, former planetarium director and historian of science Jordan D. Marché II offers the first complete account of the community of individuals and institu

    2015-07-01

    Full Text Available The aim of this paper is to demonstrate how Jaques Rancière’s pedagogical theory, intellectual emancipation, esthetics and politics as used as a basis to understand the Theater of the Oppressed as a form of re-distribution of the sensible inside contemporary society. The Theater of the Oppressed practices, able to provide social and political emancipation with esthetical resources, can renew the ways of sensible appropriation, as well as the snip of this appropriation. The “intelligentsia equality” assumption, allied to several mechanisms that can give the oppressed people the artistic means of production, will be exposed here as a voice capable of answering the contemporary challenges of political emancipation. This article has the intention to articulate an interdisciplinary perspective, because it works with conceptions from politics, philosophy, theater and education.

    Oyama, Yukio; Baba, Mamoru; Watanabe, Yukinobu

    1998-11-01

    JENDL High Energy File (JENDL-HE) is being produced by Japanese Nuclear Data Committee (JNDC) to provide common fundamental nuclear data in the intermediate energy region for many applications concerning a basic research, an accelerator-driven nuclear waste transmutation, a fusion material study, and medical applications like the radiation therapy. The first version of JENDL-HE, which contains the evaluated nuclear data up to 50 MeV, is planned to release in 1998. However, a method of integral test with which we can validate the high-energy nuclear data file has not been established. The validation of evaluated nuclear data through the integral tests is necessary to promote utilization of JENDL-HE. JNDC set up a task force in 1997 to discuss the problems concerning the integral tests of JENDL-HE. The task force members have surveyed and studied the current status of the problems for a year to obtain a guideline for development of the high-energy nuclear database. This report summarizes the results of the survey and study done by the task force for JNDC. (author)

    : Although multiple sources chronicle the practice of vascular surgery in the North African, Mediterranean, and European theaters of World War II, that of the Pacific campaign remains undescribed. Relying on primary source documents from the war, this article provides the first discussion of the management of vascular injuries in the island-hopping battles of the Pacific. It explains how the particular military, logistic, and geographic conditions of this theater influenced medical and surgical care, prompting a continued emphasis on ligation when surgeons in Europe had already transitioned to repairing arteries.

    Pion condensation in the symmetric nuclear matter is investigated on the basis of the ALS (alternating-layer-spin) model which provides a good description for the π^0 condensation. We perform energy calculations in a realistic way where the isobar (Δ)-mixing, the short range effects and the exchange energy of the interaction are taken into account. The Δ-mixing effect is built in the model state as previously done in the neutron matter. We preferentially employ G-0 force of Sprung and Banerje...

  18. Impact Force Applied on the Spent Nuclear Fuel Disposal Canister that Accidentally Drops and Collides onto the Ground

    International Nuclear Information System (INIS)

    Kwon, Young Joo

    2016-01-01

    In this paper, a mathematical methodology was theoretically studied to obtain the impact force caused by the collision between rigid bodies. This theoretical methodology was applied to compute the impact force applied on the spent nuclear fuel disposal canister that accidentally drops and collides onto the ground. From this study, the impact force required to ensure a structurally safe canister design was theoretically formulated. The main content of the theoretical study concerns the rigid body kinematics and equation of motion during collision between two rigid bodies. On the basis of this study, a general impact theory to compute the impact force caused by the collision between two bodies was developed. This general impact theory was applied to theoretically formulate the approximate mathematical solution of the impact force that affects the spent nuclear fuel disposal canister that accidentally falls to the ground. Simultaneously, a numerical analysis was performed using the computer code to compute the numerical solution of the impact force, and the numerical result was compared with the approximate mathematical solution

  20. A new equation of state for core-collapse supernovae based on realistic nuclear forces and including a full nuclear ensemble

    Furusawa, S; Togashi, H; Nagakura, H; Sumiyoshi, K; Yamada, S; Suzuki, H; Takano, M

    2017-01-01

    We have constructed a nuclear equation of state (EOS) that includes a full nuclear ensemble for use in core-collapse supernova simulations. It is based on the EOS for uniform nuclear matter that two of the authors derived recently, applying a variational method to realistic two- and three-body nuclear forces. We have extended the liquid drop model of heavy nuclei, utilizing the mass formula that accounts for the dependences of bulk, surface, Coulomb and shell energies on density and/or temperature. As for light nuclei, we employ a quantum-theoretical mass evaluation, which incorporates the Pauli- and self-energy shifts. In addition to realistic nuclear forces, the inclusion of in-medium effects on the full ensemble of nuclei makes the new EOS one of the most realistic EOSs, which covers a wide range of density, temperature and proton fraction that supernova simulations normally encounter. We make comparisons with the FYSS EOS, which is based on the same formulation for the nuclear ensemble but adopts the relativistic mean field theory with the TM1 parameter set for uniform nuclear matter. The new EOS is softer than the FYSS EOS around and above nuclear saturation densities. We find that neutron-rich nuclei with small mass numbers are more abundant in the new EOS than in the FYSS EOS because of the larger saturation densities and smaller symmetry energy of nuclei in the former. We apply the two EOSs to 1D supernova simulations and find that the new EOS gives lower electron fractions and higher temperatures in the collapse phase owing to the smaller symmetry energy. As a result, the inner core has smaller masses for the new EOS. It is more compact, on the other hand, due to the softness of the new EOS and bounces at higher densities. It turns out that the shock wave generated by core bounce is a bit stronger initially in the simulation with the new EOS. The ensuing outward propagations of the shock wave in the outer core are very similar in the two simulations, which

    1979-01-01

    This study provides a discussion of the origins and evolution of US strategic nuclear policy, the objectives an requirements of US nuclear forces, and an assessment of present and emerging US stategic nuclear policy and force structure options. It identifies the distinctive phases of US strategic nuclear policy, the conditions of the military environments in which those policies were developed, the interaction of US-Soviet strategic force and arms control processes during these phases, and the domestic debates which have accompanied US strategic nuclear policy developments. In particular, the study focuses on the major contending views which continue to characterize the debate concerning US strategic nuclear policy. The study assesses the implications of the contending views represented in what is commonly referred to as the counterforce-countervalue debate, particularly as they relate to the perception of what constitutes a credible US deterrent posture, and the corresponding alternatives that these views bring with them for making US strategic nuclear policy and force structure decisions. The arms control process, in general, and SALT I and SALT II in particular, is discussed as an integral and dynamic component of the strategic debate, fundamentally affecting the nation's security policies. The implications of modern weapons technology, and the problems inherent in preserving strategic stability between adversary nations with asymmetries in military force structures and doctrines, are also discussed. Further, the study focuses on the question of whether or not nuclear superiority can be considered relevant under the contemporary international conditions

    Full Text Available The article deals with the issues of artwork impact on ballet artists’ and ballet masters’ creativity – creation of choreographic works based on artworks. Facts (examples demonstrating such borrowing are involved, but more significantly, the range of potential opportunities, which may enrich modern ballet theater, is outlined. The matter of figurative material takes on particular importance, i.e. the issue to what extent a choreographic work reflects the essence of an artwork accurately, deeply, and adequately. The article considers the connection and mutual benefit of the processes of creative interpenetration of graphics, art, sculpture, arts and crafts, and ballet theater. Different techniques of figurative sources are studied: illustration, statement, demonstration, comparison, event localization, generalization, stylistic device, and their visualization by means of choreographic dynamics. It’s concluded the synthetic nature of ballet theatergives rise to new polygenre structures that can intensify both expressive and semantic content of choreographic image, create original stage solutions.

  5. Report of Task Force for review of nuclear waste management. Draft

    International Nuclear Information System (INIS)

    1978-02-01

    Some of the findings of the Task Force are: a majority of independent technical experts have concluded that high-level waste can be safely disposed in geological media, but validation of the specific technical choices will be an important element of the licensing process. Reprocessing is not required for the safe disposal of commercial spent fuel. Consideration should be given to an early demonstration of the geologic disposal of a limited number of spent fuel assemblies in the waste Isolation Pilot Plant. The Spent Fuel Policy announced by President Carter in October 1977 must be integrated with the Waste Management Policy. The Task Force report highlights the importance of away from reactor storage that occurs between on-site storage of spent fuel at utilities and ultimate disposal. The target for initial operation in 1985 os a National Waste Repository for the permanent disposal of commercial high-level waste as spent fuel may not be met; this does not affect the early 1980s schedule for the Waste Isolation Pilot Plant. The responsibility for the ultimate disposal for all forms of nuclear waste should be with the Federal Government and long-term waste disposal facilities should be subject to NRC licensing. The NEPA process is an essential part of the nuclear waste management program and Department of Energy efforts in this regard must be strengthened. Policy and program management responsibility for Waste Management should be raised to a higher level in the Department of Energy. There are substantial budgetary impacts of the Task Force recommendations and legislation would be required to carry out many of the suggested changes

    In this paper, evaluation of tensile force on bonded seven-wire strand embedded in nuclear reactor containments has been nondestructively investigated. For this purpose, a total of eight prestressed concrete beam specimens with different tension force levels have been fabricated and tested in terms of using an impact pulse at one end of the strand. Subsequently, various longitudinal vibration characteristics excited by the pulse have been analyzed in detailed. In short, the present study has demonstrated that longitudinal frequency, elastic wave velocity, and elastic modulus are nonlinearly increased as the tensile force level is increased. It is thus postulated that the longitudinal vibration characteristics of the existing bonded tendons can be of promising indicators for the inspection of a tensile force loss.

    Full Text Available Youth is one of the challenging issues to social development policies in Latin America. When socially vulnerable, this age group is at risk of losing future prospects in case minimum conditions are not ensured for active participation in the process of gaining citizenship. In this sense, it is important to develop actions to enable a reduction of the vulnerability process impacts in their daily lives. In this study, we aimed to describe and analyze the use of drama as a therapeutic resource with young people in occupational social vulnerability in the process of awareness and youth participation. To this end, we carried out a case study with qualitative approach in a philanthropic institution in the state of Minas Gerais. Ten meetings were conducted using drama the activities proposed by Augusto Boal, a theatrical presentation to the community using the technique of the theater-forum and focus groups. Data collection occurred through filming and the production of journals analyzed by Content Analysis. We developed three thematic categories: drama as an instrument of expression of the vulnerability conditions of young people; drama and social microcosm of the group and the family; and Theatre Forum and the development of coping strategies. Throughout the process, the technique of the theater of the oppressed enabled the critical thinking development of young people regarding the problems experienced, which helped to promote a dialogue with the community and the family. The community realized the social role of theater, reflecting on the problems experienced by youth.

    2016-12-01

    Full Text Available In this work, a creative way to teach Physics to the students in Regular Education is suggested, by presenting the following aspects: how it happened, outcomes, and the way to present it to the readers. The theater was chosen, considering that scientific knowledge can be represented beyond its rigidity, at the same time that art provokes reflections in the actor and in the spectator. A group of scientific theater was created in a school in Brejo Santo, Ceará, and besides staging, a website was elaborated. The characters "Traditional Teaching" and "New Physics" are the protagonists of the story and they will show us in their dialogues, how difficult it is, however possible, to show possibilities of Physics teaching through an entertaining approach in regular schools. Among the results, positive changes were noticed in the group, as the student's posture in classroom, besides receptivity and respect among the friends and with the teacher. Besides, they began to see Physics in another way, becoming more motivated to learn this science. In that sense, considering the current brazilian education, the objective of this work focuses on the teacher's need to act in a differentiated way, through strategies and new methodologies. Therefore, the theatrical practice, more specifically, the scientific theater, can be a tool of great didactic potential in teachers’ practice, contributing for teaching process and learning of Physics.

Hot off the SGI-Onyx Graphics-Supercomputer are NASA's visualizations of Hurricanes Mitch, Georges, Fran and Linda. These storms have been recently featured on the covers of National Geographic, Time, Newsweek and Popular Science. Highlights will be shown from the NASA hurricane visualization resource video tape that has been used repeatedly this season on National and International network TV. Results will be presented from a new paper on automatic wind measurements in Hurricane Luis from 1-min GOES images that appeared in the November BAMS. The visualizations are produced by the NASA Goddard Visualization and Analysis Laboratory (VAL/912), and Scientific Visualization Studio (SVS/930), as well as other Goddard and NASA groups using NASA, NOAA, ESA, and NASDA Earth science datasets. Visualizations will be shown from the Earth Science E-Theater 1999 recently presented in Tokyo, Paris, Munich, Sydney, Melbourne, Honolulu, Washington, New York, and Dallas. The presentation Jan 11-14 at the AMS meeting in Dallas used a 4-CPU SGI/CRAY Onyx Infinite Reality Super Graphics Workstation with 8 GB RAM and a Terabyte Disk at 3840 X 1024 resolution with triple synchronized BarcoReality 9200 projectors on a 60ft wide screen.

    International Nuclear Information System (INIS)

    Hebel, L.C.

    1991-01-01

    As the United States and the Soviet government agree on major reductions in nuclear weapon delivery systems, they need to address the disposal of the nuclear warheads and bombs for those systems. Such measures could be strongly reinforced if the two nations also institute restraints and reductions in the total amount of fissionable materials available for weapons. Many metric tonnes of such materials would be made surplus by the reductions in strategic nuclear weapons due to the Strategic Arms Reduction Treaty (START-I). Equally large reductions in short-range (theater) nuclear weapons are expected in the wake of the recent Treaty on Conventional Forces in Europe (CFE)

    A workshop sponsored by the Los Alamos National Laboratory in cooperation with the Woodrow Wilson International Center for Scholars was held at the Wilson Center in Washington, DC, on October 28, 2010. The workshop addressed evolving nuclear forces and their impacts on nonproliferation in the context of the new strategic environment, the Obama Administration's Nuclear Posture Review and the 2010 NPT Review Conference. The discussions reflected the importance of the NPR for defining the role of US nuclear forces in dealing with 21st century threats and providing guidance for National Nuclear Security Administration (NNSA) and Department of Defense (DoD) programs and, for many but not all participants, highlighted its role in the successful outcome of the NPT RevCon. There was widespread support for the NPR and its role in developing the foundations for a sustainable nuclear-weapon program that addresses nuclear weapons, infrastructure and expertise in the broader nonproliferation, disarmament and international security contexts. However, some participants raised concerns about its implementation and its long-term effectiveness and sustainability.

    In 1979, NATO announced its decision to deploy American intermediate-range nuclear missiles throughout Western Europe. From then until 1987, when the historic Intermediate-range Nuclear forces (INF) treaty provided for the withdrawal of these weapons as well as those deployed by the Soviets in Eastern Europe, the issue of nuclear weapons preoccupied many Europeans, particularly Germans. Beginning in 1980, fear of nuclear war, with the two Germanies as a potential battlefield, mobilized the largest peace movement that the Federal Republic had witnessed since the fifties, occasioned a massive increase in peace propaganda in East Germany, and brought to public notice that country's first unofficial peace movement. Throughout most of the eighties, writers in both German states opposed missile deployment. This study examines their aims and achievements in this effort and investigates the implications of political engagement for the aesthetic production of selected authors. Analysis of press reports, writers' speeches, interviews, essays and literary texts yielded the following results: INF deployment motivated writers of all political persuasions to take up a variety of peace-oriented pursuits

    Senior farmers have a 2.6-fold risk of fatal injury compared to their younger counterparts. Usual educational interventions have resulted in limited success in reducing injury. An innovative strategy, didactic readers theater, was piloted. Farmers' stories provided the foundation for the scripts. The approach incorporated adult learning strategies based on Ajzen's Theory of Planned Behavior. The intervention was marketed as a "dinner theater" to farm couples. Three short socio-novels (plays) were presented by local farmers who served as actors. Following each play participants completed a reaction form and participated in a short discussion about the play's content. One week later a phone survey was completed that tapped further reaction to the content and behavior changes. Thirty-three farm household individuals (including 16 couples) participated. Participants expressed favorable reaction to the intervention. Within one week post intervention, 42% had made safety changes and 67% were "thinking about/intending" to make changes. The use of real stories contributed to the success of this intervention. Farmers identified with the stories and began to think and talk about the impact that aging exerts on their health and safety. Interaction among the group identified work modifications which empowered the farmers to make positive changes in their own work behavior. Educational interventions with farmers have met with limited success in reducing farm-related injuries. Moreover, few interventions have utilized the family unit. This novel program, incorporating local organizations and using limited financial resources, resulted in swift behavior changes. Total Worker Health includes not only the worker, but also the family. Interventions that include family units should be considered when possible. This format is effective, easily adapted to local issues, can be delivered using existing infrastructure, and is acceptable to the farm community. It is currently being tested

    This dissertation examines the American nuclear theatre - works that directly explore nuclear technology (weapons and energy). Background chapters describe the history of nuclear development, discourse, and strategy; the response of the arts; and the history of the American nuclear theatre, which began in 1946 and burgeoned after 1980. Five recent, representative productions - four stage dramas and one nonviolent symbolic action - are examined as theatrical strategies: Dead End Kids: a History of Nuclear Power (1980), by JoAnne Akalaitis/Mabour Mines; the Story of One Who Set Out to Study Fear (1981), by Peter Schumann/Bread and Puppet Theater; Factwino vs. Armageddonman (1982), by the San Francisco Mime Troupe ; Ashes, Ashes, We All Fall Down (1982), by Martha Beosing/At the Foot of the Mountain; and the Plowshares 8 events (1980-1984). All five productions were created collaboratively. All assaulted the boundaries between art and life. All were dialectical and tried to create a fundamental shift in consciousness about nuclear weapons. All suggested that the nuclear age is a new historical situation: war and business are interconnected with a new technology which makes possible the end of the world. Three productions employed historical images of mass death to provide emotional and moral comparisons. All finally called for each audience member to take responsibility for the current nuclear situation

  8. Can Sweden be forced to manage nuclear waste from other countries?; Kan Sverige tvingas ta emot andra laenders kaernavfall?

    2005-06-01

    This report tries to answer two questions: Can Sweden, through supranational decisions, be forced to dispose of other nations nuclear waste within its own borders? and How can a Swedish stakeholder follow and influence EU-agendas, in particular concerning nuclear waste? Sometimes it has been argued that, through the EU-membership, Sweden could be forced to accept foreign radioactive waste for disposal in Sweden. However, the Swedish Nuclear Technology Act clearly states that license for final disposal spent nuclear fuels can not be given for fuel from another country than Sweden. At the Swedish EU entry it was found that the national legislation were compatible with the EU regulations, and as a consequence waste from foreign nuclear plants can not be disposed of in Sweden, even if the plant is owned by a Swedish company. Other conclusions in the report are: The system for decision making in EU is complex and slow and must be supported by supranational and international organs. The process is complex, but offers many opportunities for following-up and influencing. The risk for anything happening 'over-night' in the radioactive waste question is minimal. The issue of regulating radioactive waste management in a supranational way, i.e. by forcing a country to accept wastes from another country is not on the agenda. The Euratom treaty is interpreted in the way that such decision can not be made. The international discussions about regional repositories build upon voluntary agreements. Scenarios leading to coersive legislation are judged to be politically unrealistic - and needing important changes to be realised.

    In this paper, by using data obtained in experiments on reduced scale specimens of actual size of X type braces and by analyzing data previously obtained from K type brace experiments, we will propose simple and practical restoring force characteristics models of both types of the braces in the steel framed buildings. X and K type braces are the principal earthquake resistant elements in the steel frames of nuclear power station buildings. Therefore the results of past research and experiments were examined, and 11 reduced scale models simulating actual X type braced frames were subjected to static lateral loading tests. The simple and practical restoring force characteristics models were proposed for the design of the X and K braces. (J.P.N.)

    This report describes the methodology and results of independent verification and validation performed on a combat model in its design stage. The combat model is the Future Theater Level Model (FTLM), under development by The Joint Staff/J-8. J-8 has undertaken its development to provide an analysis tool that addresses the uncertainties of combat more directly than previous models and yields more rapid study results. The methodology adopted for this verification and validation consisted of document analyses. Included were detailed examination of the FTLM design documents (at all stages of development), the FTLM Mission Needs Statement, and selected documentation for other theater level combat models. These documents were compared to assess the FTLM as to its design stage, its purpose as an analytical combat model, and its capabilities as specified in the Mission Needs Statement. The conceptual design passed those tests. The recommendations included specific modifications as well as a recommendation for continued development. The methodology is significant because independent verification and validation have not been previously reported as being performed on a combat model in its design stage. The results are significant because The Joint Staff/J-8 will be using the recommendations from this study in determining whether to proceed with develop of the model.

    2013-01-01

    A series of atomic force microscopy (AFM) images of etched nuclear tracks has been obtained and used to calculate the nuclear track registration sensitivity parameter V(x) = Vt(x)/Vb. Due to the AFM limitations the samples were irradiated normally to the surface, and with energies attenuated in order to include the Bragg peak region in the AFM piezo-scanner z movement range. The simulation of the track profile evolution was then obtained. The different stages of etched nuclear track profiles were rendered. - Highlights: ► Using AFM we reach that Bragg peak region of etched tracks in CR-39. ► The etched track sensitivity V was calculated by data obtained by AFM. ► The evolucion of etched nuclear tracks was simulated by data achieved by AFM

    We use QCD sum rules to investigate isospin-breaking effects in nuclear matter. The isospin-breaking condensate left angle NM vertical stroke uu-dd vertical stroke NM right angle is shown to play an important role. In a reasonable model the neutron becomes (0.9±0.6) MeV more bound than the proton, providing a possible solution for the Nolen-Schiffer anomaly. The various contributions to the value are analysed. The possible consequences for nucleon-nucleon isospin-breaking forces are discussed. ((orig.))

    Musical theater performers are the "triathletes" in the performing arts. The field requires versatility in a combination of skills including dancing, singing, and drama in a high frequency of performances. The aim of this study was to analyze and evaluate the health situation of musical theater students using a complete musical educational institute as an example (n = 37). The basis for the evaluation was a questionnaire survey (standardized F 1000). All students of the school participated (20 males, 17 females). Of the students, 62% have a part-time job for financial reasons, and 67.7% state only a "partial satisfaction" with their body. Regarding injury, 45.9% claim to sustain an orthopaedic injury up to twice a year, and 29.7% up to three or four times. A total of 49 acute injuries (1.3/student) and 42 chronic complaints (1.1/student) were stated. The lower extremity was the most common acutely injured region (65.3%), followed by the spine (16.3%) and upper extremity (14.3%). Of chronic complaints, the lumbar spine was the most commonly affected area, followed by the hip joint and pelvic area. Thirty-three and 24% of acute injuries occurred during "spins" and/or "stretching," respectively. There were various causes for physical and mental problems. The results show both parallels and differences to the relevant literature. It is shown that health hazards already arise in the education of musical performers. This provides particulars for the implementation of injury prevention measures during the theoretical and practical education of musical students.

    Recent Supreme Court decisions, which interpret the 200-year-old Fourth Amendment of the US Constitution, are used to provide a brief overview of some search and seizure subjects important to management and officers responsible for physical protection of nuclear facilities. The overview is framed in practical terms in order to make the comments applicable to the everyday activity of nuclear-protective-force persons. The Supreme Court has described several exceptions where searches and seizures (arrests) are permitted without a warrant, despite the Fourth Amendment which states that warrants are always required. The seven exceptions briefly discussed are search incidents to a lawful arrest, the automobile-search exception, the suitcase or container exception, the hot-pursuit or emergency exception, the stop-and-frisk exception, the plain-view exception, and consent to be searched.

    Highlights: • A fine aircraft model of A320 was built and verified by available limited prototype impacting tests. • The influences of aircraft longitudinal crushing strength on the impact process were analyzed. • The influences of NPP containment radius on the impact force were numerically studied. • The Riera function was modified by considering the radius effect of NPP containment. - Abstract: The aircraft impact force directly influences the local failure and global response of the nuclear power plant (NPP) containment, while the existing theoretical models and the field tests were almost based on the flat target. In order to analyze the radius effect of the circular sectional containment on the impact force, a fine FE model of the commercial aircraft A320 was established and validated by the available limited full-scale F-4 Phantom impact experiment. In order to determine the force to crush the A320 FE model, the influences of aircraft longitudinal crushing strength on the impact process were analyzed based on the Riera function. Considering the containment decaying effect to aircraft impact velocity, the impact impulse was theoretically calculated, while the influences of the losses of mass and energy were not included. The numerical simulations of A320 aircrafts impacting on simplified NPP containments with different radii were conducted, which could well reproduce the airframe crushing and debris scattering. By comparison of the simulated impact impulses and the calculation values by the Riera function, the coefficients corresponding to different containment radii are derived and a fitting formula is obtained. Finally, an improved Riera function dependent on the dimensionless ratio of nuclear containment radius and aircraft wingspan is proposed.

  4. Charge symmetry of the nuclear force as off-shell constraint

    International Nuclear Information System (INIS)

    Sauer, P.U.

    1975-01-01

    Off-shell changes are generated in the 1 S 0 nucleon-nucleon interaction using the Reid soft-core potential and unitary transformations of short range. Charge symmetry is assumed for the nuclear force. The same off-shell variations of the Reid potential are employed as the hadronic part of the proton-proton interaction and as neutron-neutron interaction. The Reid potential fits the experimental proton-proton data. It also accounts for the neutron-neutron scattering length with satisfying accuracy. The off-shell behavior of the Reid potential is varied in two different ways. First, off-shell changes consistent with the experimental proton-proton data can be selected. (auth) are performed which preserve the fit to the proton-proton data. Most transformed potentials of the type attempted here are unable to yield the correct experimental value of the neutron-neutron scattering length and have to be rejected. A simple practical rule is given according to which the off-shell changes consistent with the neutron-neutron scattering length can be selected. Second, off-shell changes are performed which leave the neutron-neutron scattering length unaltered. Transformed potentials of this type have usually been employed in nuclear-structure calculations. The potentials which exhibit large off-shell effects in nuclear structure are unable to account for the experimental proton-proton data. Their off-shell effects are therefore of no physical significance, and the potentials have to be rejected. A simple practical rule is given according to which the off-shell changes consistent with the experimental proton-proton data can be selected. (U.S.)

  5. Dressed dibaryon production as a new mechanism for basic nuclear force and meson-exchange currents

    International Nuclear Information System (INIS)

    Kukulin, V.I.

    2003-01-01

    A novel concept for the nuclear force is introduced. The approach assumes that a specific dressed six-quark state (dressed dibaryon) is generated in NN collision at intermediate and short ranges. The new dressing mechanism providing π-, σ-, ρ- and ω-meson clouds around the six quark core is discussed. These novel components produce both strong intermediate-range attraction and short-range repulsion in the NN sector due to the s-channel exchange mechanism which is supplemented with conventional π- and 2π- Yukawa exchanges at intermediate and long ranges. The model developed is demonstrated to lead to numerous new effects and contributions in many fields of nuclear physics. (author)

  6. Three-body forces in nuclear matter from intermediate Δ-states in three-nucleon clusters

    International Nuclear Information System (INIS)

    Kouki, T.; Smulter, L.E.W.; Green, A.M.

    1976-10-01

    The three-body force contribution in nuclear matter is treated as a three-nucleon cluster, in which one of the nucleons becomes, in an intermediate state, a Δ(1236). All exchange diagrams are calculated and found to significantly reduce the energy per particle from the direct graph. This is contrary to earlier estimates of the exchanges, using more approximate approaches. The resulting attractive contribution is rather small, -1.1 MeV at ksub(F)=1.4 fm -1 , but the roughly linear density dependence has a crucial effect on the saturation properties. The sensitivity of the results to the correlations used, and to the two-body force spin structure, is displayed. The energy per particle from clusters with three intermediate Δ's is also estimated.

    Cells sense physical cues at the level of focal adhesions and transduce them to the nucleus by biochemical and mechanical pathways. While the molecular intermediates in the mechanical links have been well studied, their dynamic coupling is poorly understood. In this study, fibroblast cells were adhered to micropillar arrays to probe correlations in the physical coupling between focal adhesions and nucleus. For this, we used novel imaging setup to simultaneously visualize micropillar deflections and EGFP labeled chromatin structure at high spatial and temporal resolution. We observed that micropillar deflections, depending on their relative positions, were positively or negatively correlated to nuclear and heterochromatin movements. Our results measuring the time scales between micropillar deflections and nucleus centroid displacement are suggestive of a strong elastic coupling that mediates differential force transmission to the nucleus. - Highlights: • Correlation between focal adhesions and nucleus studied using novel imaging setup. • Micropillar and nuclear displacements were measured at high resolution. • Correlation timescales show strong elastic coupling between cell edge and nucleus.

    Tsuruga Unit No.2 Nuclear Power Station of the Japan Atomic Power Company is the first PWR-type 4-loop plant constructed in Japan with a prestressed concrete containment vessel (PCCV). This report describes forced vibration tests carried out on the reactor building of this plant. The following were obtained as results: (1) The results of the forced vibration tests corresponded well on the whole with design values. (2) The vibration characteristics of the PCCV observed in the tests after prestressing are no different from the ones before prestressing. This shows that the vibration properties of the PCCV are practically independent of prestressing loads. (3) A seismic response analysis of the design basis earthquake was made on the design model reflecting the test results. The seismic safety of the plant was confirmed by this analysis. (author)

    Full Text Available The reduction of risk behaviors in secondary schools is a key concern for parents, teachers, and school administrators. School is one of the primary contexts of socialization for young people; thus, the investment in school-based programs to reduce risk behaviors is essential. In this study, we report on youth who participated in an intervention designed to improve decision-making skills based on positive youth development approaches. We examine changes in decision-making skills before and after involvement in the Teen Interactive Theater Education (TITE program and retrospective self-assessment of change in knowledge, abilities, and beliefs as a result of participating in TITE (n = 127. Youth that reported increases in knowledge, abilities, and beliefs due to the intervention (n = 89 were more likely to think about the consequences of their decisions and list options before making a decision compared to their counterparts that reported less overall learning (n = 38. Implications for intervention research and stakeholders are discussed.

    2017-04-01

    Although a number of existing reviews document the health and social benefits of arts participation by older people, there are none which focus specifically on theater and drama. This article presents the findings of a study conducted as part of the UK's Arts and Humanities Research Council "Cultural Value Project." The 2-year (2013-2015) "Cultural Value Project" sought to make a major contribution to how we think about the value of arts and culture to individuals and to society. It made 72 awards: 19 critical reviews of existing bodies of research, 46 research development awards to carry out new research, and 7 expert workshop awards to facilitate discussions among academics and practitioners. Together, these awards explored the components of cultural value and the ways in which cultural value is evidenced and evaluated. Following an extensive search of academic databases and E-mail requests via relevant organizations and networks, 77 publications formed the basis for our own critical review. Our findings highlight the benefits and value of older people's theater and drama participation on health and well-being, group relationships, learning and creativity, and draw attention to the importance of the esthetic value and quality of older people's drama. Despite the recent surge of interest in this field (a third of the reviewed literature was published between 2010 and 2014), we suggest that there are multiple areas for further research. © The Author 2016.

  18. Enhancing Teaching, Adaptability and Presentation Skills through Improvisational Theater

    Directory of Open Access Journals (Sweden)

    Thomas J. Marlowe

    2014-10-01

    Full Text Available Improvisational theater, creative role-playing and open-ended scenarios are increasingly being used as ways to emphasize the importance of combining planning with flexibility and evolution to respond to changes in context. These skills and capabilities are extremely valuable in teaching, especially for strengthening communication and interpersonal skills, as well as the capacity for critical thinking and problem solving. Further, this combination of planning with flexibility is also a major theme of agile software development and a number of other problem-solving domains, and in the collaborative development of intellectual property in technical areas. With improvisation, the plan becomes less of a fixed framework, and more of a guideline. In software engineering, it becomes a mutable structure on which to hang goals and objectives, progress, processes, artifacts, and properties. In this submission, we explore the ramifications of this approach.

  1. Nuclear forces the making of the physicist Hans Bethe

    2012-01-01

    On the fiftieth anniversary of Hiroshima, Nobel-winning physicist Hans Bethe called on his fellow scientists to stop working on weapons of mass destruction. What drove Bethe, the head of Theoretical Physics at Los Alamos during the Manhattan Project, to renounce the weaponry he had once worked so tirelessly to create? That is one of the questions answered by "Nuclear Forces", a riveting biography of Bethe's early life and development as both a scientist and a man of principle. As Silvan Schweber follows Bethe from his childhood in Germany, to laboratories in Italy and England, and on to Cornell University, he shows how these differing environments were reflected in the kind of physics Bethe produced. Many of the young quantum physicists in the 1930s, including Bethe, had Jewish roots, and Schweber considers how Liberal Judaism in Germany helps explain their remarkable contributions. A portrait emerges of a man whose strategy for staying on top of a deeply hierarchical field was to tackle only those problems h...

    The establishment of a federal security force has been suggested as an additional step to protect nuclear material. The force would be given the responsibility for guarding nuclear facilities and shipments of nuclear materials. This paper summarizes a study to identify the issues that are relevant to choosing between the private guard forces that are presently employed by industry or a guard force under federal authority. To examine the issues which would be relevant, three possible types of security force structures were selected for comparison: a federal force under central authority, a private guard force employed by or under contract to a facility, and a private arrangement to employ local police officers similar to the arrangement for armed guards at airports. The issues were divided into seven categories: (1) Legal Considerations, (2) Liability, (3) Staffing and Operations, (4) Costs, (5) Relationship to Off-site Forces, (6) Management and Control, (7) Transportation

  4. Nuclear scales

    1998-12-01

    Nuclear scales are discussed from the nuclear physics viewpoint. The conventional nuclear potential is characterized as a black box that interpolates nucleon-nucleon (NN) data, while being constrained by the best possible theoretical input. The latter consists of the longer-range parts of the NN force (e.g., OPEP, TPEP, the {pi}-{gamma} force), which can be calculated using chiral perturbation theory and gauged using modern phase-shift analyses. The shorter-range parts of the force are effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spin-orbit-type observables are noted.

  7. The Ay puzzle and the nuclear force

    1999-01-01

    The nucleon-deuteron analyzing power A y in elastic nucleon-deuteron scattering poses a longstanding puzzle. At energies E lab below approximately 30 MeV, A y cannot be described by any realistic NN force. The inclusion of existing three-nucleon forces does not improve the situation. Because of recent questions about the 3 P J NN phases, we examine whether reasonable changes in the NN force can resolve the puzzle. In order to do this, we investigate the effect on the 3 P J waves produced by changes in different parts of the potential (viz., the central force, tensor force, etc.), as well as on the 2-body observables and on A y . We find that it is not possible with reasonable changes in the NN potential to increase the 3-body A y , and at the same time to keep the 2-body observables unchanged. We therefore conclude that the A y puzzle is likely to be solved by new three-nucleon forces, such as those of spin-orbit type, which have not yet been taken into account. Refs. 7, tab. 1 (author)

    1998-01-01

    Decontamination and maintenance in hot cells are some new emerging applications of industrial robots in the nuclear fuel cycle plants. Industrial robots are low cost, accurate and reliable manipulator arms which are used in manufacturing industries usually. Thanks to the recent evolution of robotics technologies, some industrial robots may be adapted to nuclear environment. These robots are transportable, sealed and can be decontaminated, and they may be 'hardened' up to a level of irradiation dose sufficient for operation in low and medium irradiating/contaminating environments. Although industrial robots are usually programmed to perform specific and repetitive tasks, they may be remotely tele-operated by human operators as well. This allows industrial robots to perform usual tele-manipulation tasks encountered in the nuclear plants and more. The paper presents the computer based tele-operation control system TAO2000 TM , developed by the Tele-operation and Robotics Service of CEA, which has been applied to the RX90 TM industrial robot from ST-UBLI company. This robot has been selected in order to perform various maintenance and decontamination tasks in COGEMA plants. TAO2000 provides the overall tele-robotic and robotic functions necessary to perform any remote tele-operation application in hostile environment: force-feedback master-slave control; computer- assisted tele-operation of mechanical processes; trajectory programming as well as various robotics functions; graphical modelling of working environment and simulation; automatic path planning with obstacle avoidance; man-machine interface for tasks programming and mission execution. Experimental results reported in the paper demonstrate the feasibility of force-feedback master-slave control of standard industrial robots. Finally, the design of new, cost effective. tele-operation systems based on industrial robots may be intended for nuclear plants maintenance. (author)

  12. Nuclear performance and reliability

    International Nuclear Information System (INIS)

    Rothwell, G.

    1993-01-01

    If fewer forced outages are a sign of improved safety, nuclear power plants have become safer and more productive. There has been a significant improvement in nuclear power plant performance, due largely to a decline in the forced outage rate and a dramatic drop in the average number of forced outages per fuel cycle. If fewer forced outages are a sign of improved safety, nuclear power plants have become safer and more productive over time. To encourage further increases in performance, regulatory incentive schemes should reward reactor operators for improved reliability and safety, as well as for improved performance

  13. Recent advances in the theory of nuclear forces and its relevance for the microscopic approach to dense matter

    International Nuclear Information System (INIS)

    Machleidt, R.

    2010-01-01

    The theory of nuclear forces has made great progress since the turn of the millenium using the framework of chiral effective field theory (ChEFT). The advantage of this approach, which was originally proposed by Weinberg, is that it has a firm basis in quantum-chromodynamics and allows for quantitative calculations. Moreover, this theory generates two-nucleon forces (2NF) and many-body forces on an equal footing and provides an explanation for the empirically known fact that 2NF ≫ 3NF ≫ 4NF. I will present the recent advances in more detail and put them into historical context. In addition, I will also provide a critical evaluation of the progress made including a discussion of the limitations of the ChEFT approach. (author)

  14. Baryonic forces and hyperons in nuclear matter from SU(3) chiral effective field theory

    2016-02-12

    In this work the baryon-baryon interaction is studied at next-to-leading order in SU(3) chiral effective field theory and applied to hyperon-nucleon scattering. The properties of hyperons in isospin-symmetric as well as asymmetric nuclear matter are calculated within the Bruecker-Hartree-Fock formalism. Moreover, the leading three-baryon interaction is derived and its low-energy constants are estimated from decuplet intermediate states. We conclude, that chiral effective field theory is a well-suited tool to describe the baryonic forces.

  16. Effects of tensor forces in nuclei

    International Nuclear Information System (INIS)

    Tanihata, Isao

    2013-01-01

    Recent studies of nuclei far from the stability line have revealed drastic changes in nuclear orbitals and reported the appearance of new magic numbers and the disappearance of magic numbers observed at the stability line. One of the important reasons for such changes is considered to be because of the effect of tensor forces on nuclear structure. Although the role of tensor forces in binding very light nuclei such as deuterons and 4 He has been known, direct experimental evidence for the effect on nuclear structure is scarce. In this paper, I review known effects of tensor forces in nuclei and then discuss the recently raised question of s–p wave mixing in a halo nucleus of 11 Li. Following these reviews, the development of a new experiment to see the high-momentum components due to the tensor forces is discussed and some of the new data are presented. (paper)

    Full Text Available This article is a dialogue between two practitioners of Image theater—a technique which involves using the body to share stories. Working in Quebec and Scotland, we discuss the potential ways such a form of performative inquiry (FELS, 1998 can, through an online medium, be documented and disseminated in ways that are coherent with, and build on, the principles of interactive theater. Our hope is that such an exploration will enable the participants in the work, ourselves, and our readers as performative social science researchers, so that we may engage as spect-actors (BOAL, 1979 with the material and build communities of practice through reflection on action (praxis. A key aspect we consider is ways in which physical dialogue through the body evolves—first as a method of enacting the world, where collective meaning emerges and secondly, as a concept that uses symbolic/metaphoric aesthetic language through what one colleague calls "body-storming" (like "brain-storming," but with the emotional and sensory body as a source and language of expression.

    1982-01-01

    A computer code was developed as one of the tools needed for analysis of piping dynamic loading on nuclear power plant high energy piping systems, including reactor safety and relief value upstream and discharge piping systems. The code calculates the transient hydraulic data and dynamic forces within the one-dimensional system, caused by a pipe rupture or sudden value motion, using a fixed space and varying time grid-method of characteristics. Subcooled, superheated, homogeneous two-phase and transition flow regimes are considered. A non-equilibrium effect is also considered in computing the fluid specific volume and fluid local sonic velocity in the two-phase mixture. Various hydraulic components such as a spring loaded or power operated value, enlarger, orifice, pressurized tank, multiple pipe junction (tee), etc. are considered as boundary conditions. Comparisons of calculated results with available experimental data shows a good agreement. (Author)

  1. Exotic Nuclei and Yukawa's Forces

    International Nuclear Information System (INIS)

    Otsuka, Takaharu; Suzuki, Toshio; Utsuno, Yutaka

    2008-01-01

    In this plenary talk, we will overview the evolution of the shell structure in stable and exotic nuclei as a new paradigm of nuclear structure physics. This shell evolution is primarily due to the tensor force. The robust mechanism and some examples will be presented. Such examples include the disappearance of existing magic numbers and the appearance of new ones. The nuclear magic numbers have been believed, since Mayer and Jensen, to be constants as 2, 8, 20, 28, 50, ... This turned out to be changed, once we entered the regime of exotic nuclei. This shell evolution develops at many places on the nuclear chart in various forms. For example, superheavy magic numbers may be altered. Thus, we are led to a new paradigm as to how and where the nuclear shell evolves, and what consequences arise. The evolution of the shell affects weak process transitions, and plays a crucial role in deformation. The π and ρ mesons generate tensor forces, and are the fundamental elements of such intriguing phenomena. Thus, physics of exotic nuclei arises as a manifestation of Yukawa's forces

    2017-01-01

    This article deals with the problem of the control mode choice for a power supply system in case of force majeure circumstances. It is not known precisely, when a force majeure incident occurs, but the threatened period is given, when the incident is expected. It is supposed, that force majeure circumstances force nuclear reactor shutdown at the moment of threat coming. In this article the power supply system is considered, which consists of a nuclear reactor and a reserve power supply, for example, a hydroelectric pumped storage power station. The reserve power supply has limited capacity and it doesn’t undergo the threatened incident. The problem of the search of the best reserve supply time-distribution in case of force majeure circumstances is stated. The search is performed according to minimization of power loss and damage to the infrastructure. The software has been developed, which performs automatic numerical search of the approximate optimal control modes for the reserve power supply.

  3. Benchmarking of thermalhydraulic loop models for lead-alloy-cooled advanced nuclear energy systems. Phase I: Isothermal forced convection case

    International Nuclear Information System (INIS)

    2012-06-01

    Under the auspices of the NEA Nuclear Science Committee (NSC), the Working Party on Scientific Issues of the Fuel Cycle (WPFC) has been established to co-ordinate scientific activities regarding various existing and advanced nuclear fuel cycles, including advanced reactor systems, associated chemistry and flowsheets, development and performance of fuel and materials and accelerators and spallation targets. The WPFC has different expert groups to cover a wide range of scientific issues in the field of nuclear fuel cycle. The Task Force on Lead-Alloy-Cooled Advanced Nuclear Energy Systems (LACANES) was created in 2006 to study thermal-hydraulic characteristics of heavy liquid metal coolant loop. The objectives of the task force are to (1) validate thermal-hydraulic loop models for application to LACANES design analysis in participating organisations, by benchmarking with a set of well-characterised lead-alloy coolant loop test data, (2) establish guidelines for quantifying thermal-hydraulic modelling parameters related to friction and heat transfer by lead-alloy coolant and (3) identify specific issues, either in modelling and/or in loop testing, which need to be addressed via possible future work. Nine participants from seven different institutes participated in the first phase of the benchmark. This report provides details of the benchmark specifications, method and code characteristics and results of the preliminary study: pressure loss coefficient and Phase-I. A comparison and analysis of the results will be performed together with Phase-II

    This case report describes the first case in intraoperative magnetic resonance imaging operating theater (iMRI OT) (BrainSuite®) of awake craniotomy for frontal lobe glioma excision in a 24-year-old man undergoing eloquent cortex language mapping intraoperatively. As he was very motivated to take pictures of him while being operated upon, the authors adapted conscious sedation technique with variable depth according to Ramsey's scale, in order to revert to awake state to perform the intended neurosurgical procedure. The patient tolerated the situation satisfactorily and was cooperative till the finish, without any event. We elicit in this report the special environment of iMRI OT for lengthy operation in pinned fixed patient having craniotomy. PMID:25885085

    Training medical students to understand the effects of culture and marginalization on health outcomes is important to the future health of increasingly diverse populations. We devised and evaluated a short training module on working with diversity to challenge students’ thinking about the role of both patient and practitioner culture in health outcomes. The workshop combined didactic teaching about culture as a social determinant of health using the cultural humility model, interactive exercises, and applied theater techniques. We evaluated changes in the students’ perceptions and attitudes over time using the Reaction to Diversity Inventory. There was initial significant improvement. Women and students with no past diversity training responded best. However, scores largely reverted to baseline over 12 months. PMID:29349320

    Full text: The Third Conference on Facilitating the Entry into Force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) is being held at a time of major challenges to the nuclear arms control and disarmament regime. A verified, permanent, global ban on all types of nuclear explosive tests has been a key item on the international security agenda for nearly half a century. More than 2,000 nuclear explosive detonations have taken place since 1945, with the most recent ones in 1998. The CTBT has been characterized as the longest sought, hardest fought prize in the history of arms control. The Treaty, when implemented, will prohibit all nuclear explosions, in all environments, for all time. It will curb the development and testing of new, more advanced and more dangerous nuclear weapons, and will limit the possibilities for further nuclear proliferation. The Treaty will lead to the establishment of a comprehensive International Monitoring System to provide independent, impartial verification of compliance. The CTBT, along with the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), and a future Treaty Banning the Production of Fissile Material for Nuclear Weapons and Other Nuclear Explosive Devices (FMCT), forms an essential element of a network of negotiated, global treaties that will strengthen international efforts to prevent the further spread of nuclear weapons and to promote nuclear disarmament leading in time hopefully to a world without nuclear weapons. In the meantime, with the early entry into force of the CTBT, it would indeed be a significant achievement if this new century were to remain free of any nuclear test explosions. In this context, I encourage all signatory States to ratify the CTBT, and all those States that have yet to sign to do so and to ratify the Treaty, as soon as possible - so that another crucial pillar can be raised to support the edifice of global nuclear non-proliferation and nuclear disarmament norms.

    Sun protection in childhood is important to reduce the risk of developing skin cancer later in life. The "Periods-of-Life-Program" for primary prevention of skin cancer introduces a combination of individual and environmental interventions for the preschool period. Within this pilot study, an intervention group received cognitive-behavioral and environmental interventions. A control group had solely received the environmental intervention, and a wait-control group received no intervention. Nursery school children (n = 80, 3 to 6 years of age) of four nursery schools were randomly assigned to these groups on school level. The ability of the cognitive-behavioral intervention (a theater play) to enhance sun protection knowledge was examined. The theater play improved knowledge over all age groups (p < .05 η(2) = .06). Age-specific analyses showed better results for children aged 5 to 6 (p < .05 η(2) = .20) compared to children aged 3 to 4 years (p = .17 η(2) = .04). In combining cognitive-behavioral and environmental interventions, the "Periods-of-Life-Program" is a promising strategy for primary prevention of skin cancer.

    Full Text Available The aim of the study was to know the response of the relatives attending the squint surgery of their ward. A trained secretary administered an eight item questionnaire by live / telephonic interview. Of the 44 attendees, two left the Operation Theater before completion of the surgery. Mean age of the patients was 7.2 years ± 7.8 and that of the attendees was 36.1 years ± 8.5. Forty patients had a surgery under general anesthesia and four under local anesthesia. Eleven (25% attendees experienced an increase in anxiety. Thirty-six (82% attendees reported increased transparency, 38 (86% reported increased confidence, and 43 (98% reported increased awareness. None found any disadvantage. Twenty-seven (61% recommended this practice for all and 16 (36% recommended the practice selectively. The internal validity of the questionnaire was fair (Cronbach′s Alpha = 0.6. It was concluded that the presence of relatives in the Operation Theater during the surgery could bring in more transparency, accountability, confidence, awareness, and trust.

    Exposure therapy (ET) has been observed to be an effective modality for the treatment of combat-related posttraumatic stress disorder (PTSD). Recently, efforts have been made to use virtual reality (VR) to enhance outcome with modes of ET. How such therapy applies to service members who are facing the reality of a combat deployment has been unknown. This case series documents the first use of VR-based therapy to the treatment of PTSD in a combat theater. Results of therapy are reported from a mental health clinic in Camp Fallujah, Iraq. Combat PTSD constituted a relatively small percentage of overall mental health patients seen. Those who did present with PTSD were offered VR-based ET or traditional ET. Patients who received either treatment modality showed significant gains, and no service member in treatment had to be medically evacuated because of ongoing PTSD symptoms. This demonstrates that ET, with or without the use of VR, can be an effective means of helping service members with mental health issues while they serve in theater.

  12. Europe's nuclear superpowers

    1984-01-01

    Both Great Britain and France are on the verge of nuclear buildups ambitious enough to turn either one into the world's third nuclear superpower. The authors note that the expansion of British and French arsenals will add greatly to the West's nuclear firepower, but on balance these forces will actually weaken Western security. The reason is that they will be deployed largely in potentially vulnerable and destabilizing modes. In addition, they will threaten the unity of the North Atlantic Treaty Organization (NATO) and the viability of the alliance's nuclear doctrine. Perhaps most important, these forces will almost certainly spark a counterbuild-up by the Soviets and fatally complicate the task of arms control. The authors feel, therefore, that the time to include British and French forces in nuclear arms talks is now - before the planned increase in their nuclear might takes place. London and Paris have authorized programs that can give them unprecedented influence with the superpowers and should use this opportunity to slow the arms race, not supercharge it

    While the responsibility for nuclear security at the national level rests entirely with each state, international co-operation can be crucial in helping states to fulfil their nuclear security responsibilities and obligations. The central role of the International Atomic Energy Agency (IAEA) in strengthening the nuclear security framework and leading the co-ordination of international activities in the field of nuclear security is now widely recognised. Although much has been done to help states in improving nuclear security, by and under the auspices of the IAEA and other intergovernmental organisations, nuclear terrorism has gained a global recognition as one of the most challenging threats to global security in the 21. century Reports by IAEA member states to the IAEA's Incident and Trafficking Database (ITDB) indicate that nuclear material continues to go missing. Also, too many nuclear facilities are still inadequately protected and sabotage thereof is a threat. Border security remains lax in too many places and the possibility for nuclear smuggling may exist. Attempts by individuals and groups of persons are still made to acquire nuclear material for terrorist and other malicious purposes. The threat of nuclear terrorism remains real. Adopted under the auspices of the IAEA on 8 July 2005, the Amendment to the Convention on the Physical Protection of Nuclear Material ('Amendment') and the existing convention, the Convention on the Physical Protection of Nuclear Material (CPPNM or 'Convention') of 1980, are one of a number of treaties comprising the international legal framework on nuclear security. As will be explained later in the article, the Amendment expands and deepens the effect of the CPPNM. However, more than nine years after its adoption and despite the perceived threat and recognised need to strengthen the CPPNM dating back some 15 years ago, the Amendment is still not in force. Although to some CPPNM states parties, the pressing need for the

    This book is about change: in the Soviet Union, in Eastern Europe, and how we in the West should respond. Few observers of the international scene, even in their wildest dreams, could have imagined the course of events that have taken place in Europe since early 1989. The communist system came to a dead end. Old social, economic, political, and psychological recipes no longer were acceptable, either in the Soviet Union or in Eastern Europe. Soviet leadership had only two choices: repress change in Eastern Europe and demand continued sacrifices from its own people, or press forward on the road of economic reform and political restructuring at home and the pursuit of new relationships abroad. The three volumes on Alternative Conventional Defense Postures in the European Theater contributed significantly to the current debate in Europe and in the United States on the future of European security. As an outgrowth of a German-American workshop at the Army War College in Carlisle, Pennsylvania, the two editors have succeeded in bringing together statesmen, soldiers, and civilian defense specialist from the Federal Republic, the United States, and the Soviet Union, who represent a variety of schools of political and strategic thinking

    Full Text Available Training medical students to understand the effects of culture and marginalization on health outcomes is important to the future health of increasingly diverse populations. We devised and evaluated a short training module on working with diversity to challenge students’ thinking about the role of both patient and practitioner culture in health outcomes. The workshop combined didactic teaching about culture as a social determinant of health using the cultural humility model, interactive exercises, and applied theater techniques. We evaluated changes in the students’ perceptions and attitudes over time using the Reaction to Diversity Inventory. There was initial significant improvement. Women and students with no past diversity training responded best. However, scores largely reverted to baseline over 12 months.

    1982-01-01

    As one of the projects at the National Laboratory of High Energy Physics (KEK), the measurement of parity non-conservation component in nuclear force was proposed. The theoretical survey of this proposal is reported. The non-relativistic parity non-conserving potential between nucleons can be obtained from the interaction between a quark and a gauge boson. The wave function of a nucleus, which includes the inverse components of the parity, can be written. A practical experiment was designed. The mixing of the inverse components and the interference of an inverse component in the 1042 keV and 1081 keV levels of F 18 may produce the parity non-conservation. The processes which suggest the existence of parity non-conservation were studied. The processes are the circular polarization of gamma-ray emitted from a nucleus, the angular distribution of gamma-ray emitted from polarized nuclei, the collision of the proton beam with helicity of plus and minus on other nuclei, the spin rotation of neutrons, and the alpha decay of the parity non-conservation. The preliminary results of the experiment on the effects of parity non-conservation in the collision process of polarized proton beam have been reported, and the theoretical analyses were performed. The violation of parity conservation in large momentum collision is discussed. The comparison of the theoretical results with the experimental ones is presented. (Kato, T.)

    Most critically ill injured patients are transported out of the theater by Critical Care Air Transport Teams (CCATTs). Fever after trauma is correlated with surgical complications and infection. The purposes of this study are to identify the incidence of elevated temperature in patients managed in the CCATT environment and to describe the complications reported and the treatments used in these patients. We performed a retrospective review of available records of trauma patients from the combat theater between March 1, 2009, and March 31, 2010, who were transported by the US Air Force CCATT and had an incidence of hyperthermia. We then divided the cohort into 2 groups, patients transported with an elevation in temperature greater than 100.4°F and patients with no documented elevation in temperature. We used a standardized, secure electronic data collection form to abstract the outcomes. Descriptive data collected included injury type, temperature, use of a mechanical ventilator, cooling treatment modalities, antipyretics, intravenous fluid administration, and use of blood products. We also evaluated the incidence of complications during the transport in patients who had a recorded elevation in temperature greater than 100.4°F. A total of 248 trauma patients met the inclusion criteria, and 101 trauma patients (40%) had fever. The mean age was 28 years, and 98% of patients were men. The mechanism of injury was an explosion in 156 patients (63%), blunt injury in 11 (4%), and penetrating injury in 45 (18%), whereas other trauma-related injuries accounted for 36 patients (15%). Of the patients, 209 (84%) had battle-related injuries and 39 (16%) had non-battle-related injuries. Traumatic brain injury was found in 24 patients (24%) with an incidence of elevated temperature. The mean temperature was 101.6°F (range, 100.5°F-103.9°F). After evaluation of therapies and treatments, 80 trauma patients (51%) were intubated on a mechanical ventilator (P cooling interventions

    Live theater is typically designed to alter the state of mind of the audience. Indeed, the perceptual inputs issuing from a live theatrical performance are intended to represent something else, and the actions, emphasized by the writing and staging, are the key prompting the adhesion of viewers to fiction, i.e., their belief that it is real. This phenomenon raises the issue of the cognitive processes governing access to a fictional reality during live theater and of their cerebral underpinnings. To get insight into the physiological substrates of adhesion we recreated the peculiar context of watching live drama in a functional magnetic resonance imaging (fMRI) experiment, with simultaneous recording of heart activity. The instants of adhesion were defined as the co-occurrence of theatrical events determined a priori by the stage director and the spectators' offline reports of moments when fiction acted as reality. These data served to specify, for each spectator, individual fMRI time-series, used in a random-effect group analysis to define the pattern of brain response to theatrical events. The changes in this pattern related to subjects' adhesion to fiction, were investigated using a region of interest analysis. The results showed that adhesion to theatrical events correlated with increased activity in the left BA47 and posterior superior temporal sulcus, together with a decrease in dynamic heart rate variability, leading us to discuss the hypothesis of subtle changes in the subjects' state of awareness, enabling them to mentally dissociate physical and mental (drama-viewing) experiences, to account for the phenomenon of adhesion to dramatic fiction.

Um conceito central é o de partilha do sensível, formulado por Jacques Rancière. O texto discute as formas que a partilha do sensível configura tanto no teatro quanto na psicologia comunitária quando estes se propõem a ser vetores da transformação social, e aponta entraves quando estes se limitam à representação convencional dos conflitos sociais. Outro aspecto considerado é a necessidade de dar mais relevo aos processos de produção de desejo na comunidade.This essay aims to discuss psychology and theater, their relations and possible effects when they are both involved with the production of subjectivity in popular communities. One main concept is the distribution of the sensible, created by Jacques Rancière. The text analyses the distribution of the sensible performed by the theater and by community psychology when they search social transformation. This study's conclusions indicate that the persistence of the conventional representation of the social conflicts constitutes an obstacle shared by psychology and theater, and point to the necessity of giving more relevance to the production of desire in the community.

    A new table of the nuclear equation of state (EOS) based on realistic nuclear potentials is constructed for core-collapse supernova numerical simulations. Adopting the EOS of uniform nuclear matter constructed by two of the present authors with the cluster variational method starting from the Argonne v18 and Urbana IX nuclear potentials, the Thomas–Fermi calculation is performed to obtain the minimized free energy of a Wigner–Seitz cell in non-uniform nuclear matter. As a preparation for the Thomas–Fermi calculation, the EOS of uniform nuclear matter is modified so as to remove the effects of deuteron cluster formation in uniform matter at low densities. Mixing of alpha particles is also taken into account following the procedure used by Shen et al. (1998, 2011). The critical densities with respect to the phase transition from non-uniform to uniform phase with the present EOS are slightly higher than those with the Shen EOS at small proton fractions. The critical temperature with respect to the liquid–gas phase transition decreases with the proton fraction in a more gradual manner than in the Shen EOS. Furthermore, the mass and proton numbers of nuclides appearing in non-uniform nuclear matter with small proton fractions are larger than those of the Shen EOS. These results are consequences of the fact that the density derivative coefficient of the symmetry energy of our EOS is smaller than that of the Shen EOS.

    2016-10-01

    Full Text Available Discourse is made of several voices, a premise that was announced since Bakhtin’s studies. The advances in the field of intertextuality allowed a wider specification of the term and broaden the discussion of many different occurrence of the intertext in literature. The work of a German contemporary playwright, Dea Loher, brings the recurrence of intertext, and the present paper aims to investigate this manifestation in two of her plays, Olgas Raum and Licht. Loher uses citation, references and allusions, cutting pieces of other texts and pasting them into her writing. This game of cutting and pasting is also visible inside her aesthetic, as she uses elements that are part of other theatrical aesthetics and adapts them in her work, creating an original style. Representing the political side of theater, Loher provides her reader with the possibility of reflecting and, in the considered two plays, she does it through the deconstruction of the canonic discourse, showing how discourses are made and how they are connected to power maintenance. This way, intertext, the hybrid aesthetic and other aesthetical and linguistic resources are organized to receive these political themes that come to the reader as questions and inquires.

  19. Sacral Theater, a code to simulate the propagation of the superconducting magnet LHC atlas barrel toroid transition

    Gastineau, B.

    2000-06-01

    Sacral Theater has been developed for the toroid magnet Atlas of the CERN LHC project. This three dimensional calculations code calculates the propagation of the transition of a superconducting coil in 25 m long hippodrome. Procedures to study low currents have been included. This work is a part of the magnet safety system because the coils protection is made by warmers activating the quench propagation in case of default detection. This allows the complete dissipation of storage energy that can reach 1080 MJ on Atlas. (N.C.)

  20. Epilepsy and secondary perceived stigma in a social setting: A night at the theater.

    Stigma impacts >50% of persons with epilepsy (PWE) and is a key factory in quality of life. Stigma can be both enacted (external factors) and felt (internal factors). In this article, felt/perceived stigma is more broadly defined as a combination of internal factors and perceptions of external factors. Secondary perceived stigma is felt/perceived stigma by a third party. A key, but often underappreciated, consideration in felt/perceived stigma may occur when a seemingly innocuous statement by a speaker is perceived as stigmatizing by the PWE and/or even by an unintended third party. This autobiographic short report addresses secondary perceived stigma in a social setting, the theater. Copyright © 2016 Elsevier Inc. All rights reserved.

  1. Three lectures on macroscopic aspects of nuclear dynamics

    International Nuclear Information System (INIS)

    Swiatecki, W.J.

    1979-03-01

    These lectures concentrate on macroscopic aspects of nuclear dynamics, those aspects that come into prominence when the number of nucleons, A, is large, A >> 1. An attempt is made to set up a theory of the dynamics of nuclear shape changes, for small (sub-sonic) collective velocities. To set up the equations of motion one needs three forces: conservative, dissipative, and inertial. The first lecture deals with statics, i.e., it discusses methods of treating the Potential Energy Function of nuclear systems. From the Potential Energy the conservative forces that drive the time evolution of a nuclear configuration can be deduced. The division of the underlying potential energy into Local, Proximity, and Global terms is stressed. The second lecture deals with dynamical aspects, especially with the nuclear Dissipation Function, which describes how dissipative frictional forces oppose the conservative driving forces. The underlying physics is the approximate validity of the Independent-Particle model. This, combined with the Randomization Hypothesis, leads to simple formulas that suggest that dissipative forces may often overshadow the inertial forces. The third lecture outlines the kind of dynamics that results from the balance of these forces, and describes a number of applications to nuclear fission and heavy-ion collisions of this New Dynamics. Particularly simple equations of motion are set up, and some of the consequences are explored. 18 references, 31 figures, 3 tables

  2. Theoretical studies in nuclear reactions and nuclear structure

    International Nuclear Information System (INIS)

    1992-05-01

    Research in the Maryland Nuclear Theory Group focusses on problems in four basic areas of current relevance. Hadrons in nuclear matter; the structure of hadrons; relativistic nuclear physics and heavy ion dynamics and related processes. The section on hadrons in nuclear matter groups together research items which are aimed at exploring ways in which the properties of nucleons and the mesons which play a role in the nuclear force are modified in the nuclear medium. A very interesting result has been the finding that QCD sum rules supply a new insight into the decrease of the nucleon's mass in the nuclear medium. The quark condensate, which characterizes spontaneous chiral symmetry breaking of the late QCD vacuum, decreases in nuclear matter and this is responsible for the decrease of the nucleon's mass. The section on the structure of hadrons contains progress reports on our research aimed at understanding the structure of the nucleon. Widely different approaches are being studied, e.g., lattice gauge calculations, QCD sum rules, quark-meson models with confinement and other hedgehog models. A major goal of this type of research is to develop appropriate links between nuclear physics and QCD. The section on relativistic nuclear physics represents our continuing interest in developing an appropriate relativistic framework for nuclear dynamics. A Lorentz-invariant description of the nuclear force suggests a similar decrease of the nucleon's mass in the nuclear medium as has been found from QCD sum rules. Work in progress extends previous successes in elastic scattering to inelastic scattering of protons by nuclei. The section on heavy ion dynamics and related processes reports on research into the e + e - problem and heavy ion dynamics

  3. On the dynamic fracture toughness and crack tip strain behavior of nuclear pressure vessel steel: Application of electromagnetic force

    International Nuclear Information System (INIS)

    Yagawa, G.; Yoshimura, S.

    1986-01-01

    This paper is concerned with the application of the electromagnetic force to the determination of the dynamic fracture toughness of materials. Taken is an edge-cracked specimen which carries a transient electric current and is simply supported in a steady magnetic field. As a result of their interaction, the dynamic electromagnetic force occurs in the whole body of the specimen, which is then deformed to fracture in the opening mode of cracking. Using the electric potential and the J-R curve methods to determine the dynamic crack initiation point in the experiment, together with the finite element method to calculate the extended J-integral with the effects of the electromagnetic force and inertia, the dynamic fracture toughness values of nuclear pressure vessel steel A508 class 3 are evaluated over a wide temperature range from lower to upper shelves. The strain distribution near the crack tip in the dynamic process of fracture is also obtained by applying a computer picture processing. (orig.)

  4. The mechanisms underlying corrosion product formation and deposition in nuclear power plant circuits through the action of galvanic and thermal electromotive forces

    1983-01-01

    From a theoretical standpoint, the processes of formation of corrosion products in nuclear power plant circuits, deposition of corrosion products on the circuit surfaces, formation of an equilibrium concentration of corrosion products in the coolant, and distribution of radionuclides resulting from corrosion in different parts of the circuit are considered. It is shown that the main driving forces for the mass-transfer processes in the circuits are the thermal and galvanic electromotive forces (EMF) of the microcouples. On the basis of the theoretical concepts developed the authors have obtained analytical dependences for calculating the individual stages of the process of corrosion product transfer in the circuits. The mechanisms underlying the processes which occur as a result of thermal and galvanic EMFs are considered, together with the factors influencing these processes. The results of verification of the dependences by computational methods are given and they are compared with operational data from nuclear and conventional thermal power plants and with experimental data.

    2018-02-23

    Currently, networking has not progressed in the treatment room. Almost every medical device in the treatment room operates as a stand-alone device. In this project, we aim to develop a networked operating room called "Smart Cyber Operating Theater (SCOT)". Medical devices are connected using Open Resource interface for the Network (ORiN) technology. In this paper, we describe the concept of the SCOT project. SCOT is integrated using the communication interface ORiN, which was originally developed for industry. One feature of ORiN is that the system can be constructed flexibly. ORiN creates abstracts of the same type of devices and increases the robustness of the system for device exchange. By using ORiN technology, we are developing new applications, such as decision-making navigation or a precision guided treatment system.

  12. Family planning uses traditional theater in Mali.

    Science.gov (United States)

    Schubert, J

    1988-01-01

    Mali's branch of the International Planned Parenthood Federation has found a vehicle that effectively conveys the idea of family planning through the use of contraception, a method that blends the country's cultural heritage and modern technology. Despite becoming the first sub-Saharan francophone country to promote family planning, Mali only counted 1% of its population using a modern method of contraception. So with the aid of The Johns Hopkins University/Population COmmunication Services (JHU/PCS), the Association Malienne pour la Protection et la Promotion de la Famille (AMPPF) developed several programs to promote contraception, but none were more successful than the Koteba Project, which used Mali's traditional theater form to communicate the message. While comical, the Koteba generally deals with social issues -- it informs and entertains. This particular Koteba told the story of two government employees, one with two wives and many children, the other with one wife and few children. The first one sees nothing but family problems: fighting wives and delinquent children. The second one, who had used family planning, enjoys a peaceful home. Upon hearing of his friend's successes with family planning, the tormented government employee becomes convinced of its needs, and persuades his wives to accompany him to a family planning clinic. Developed at a cost of approximately US $3000 and televised nationwide, the Koteba proved effective. A survey of 500 people attending an AMPPF clinic revealed that 1/4 of them remembered the program. With the success of the Koteba, JHU/PCS and AMPPF are now exploring other traditional channels of communication.

    2015-01-01

    This report first outlines that nuclear installations are subject to illegal intrusions which challenge their safety and security. It outlines that these installations are extremely sensitive and particularly threatened (the energy sector, as a key sector, is submitted to a specific regulation, and threats are potentially serious), that, beyond the terrorist threat and the risk of sabotage, nuclear installations are regularly facing other illegal behaviours (illegal intrusions are a recurrent issue, and drones are emerging as a new kind of threat), that the protection of nuclear installations is carried out by forces dedicated to this mission (a specialised military force for EDF sites, civil forces for the CEA and Areva, the role of the French Air Force to protect airspace), and that recent legal advances must be deepened. The second part outlines that the present legal protection framework in inadequate and incomplete. The French legal regime is presented and some foreign examples are evoked, and the need of creation of a specific penal regime is outlined. The general discussion and the discussion of the bill project articles are reported. A table proposes a comparative overview between the existing arrangement, the bill project text, and the Commission's text

  16. Project ATTACK and Project VISTA: Benchmark studies on the road to NATO's early TNF policy

    International Nuclear Information System (INIS)

    Garrity, P.J.

    1994-01-01

    This paper is concerned with those studies and analyses that affected early NATO nuclear policy and force structure. The discussion focuses specifically on two open-quotes benchmarkclose quotes activities. Project VISTA and Project ATTACK. These two studies were chosen less because one can document their direct impact on NATO nuclear policy and more because they capture the state of thinking about tactical nuclear weapons at a particular point of time. Project VISTA offers an especially important benchmark in this respect. Project ATTACK is a rather different kind of benchmark. It is not a pathbreaking study. It is much narrower and more technical than VISTA. It appears to have received no public attention. Project ATTACK is interesting because it seems to capture a open-quotes nuts-and-boltsclose quotes feel for how U.S. (and thereby NATO) theater nuclear policy was evolving prior to MC 48. The background and context for Project VISTA and Project ATTACK are presented and discussed

    International Nuclear Information System (INIS)

    Udagawa, Takeshi

    2006-01-01

    Yukawa and Tomonaga made epoch-making contributions to the development of elementary particle physics; Yukawa proposed the meson theory of the nuclear force and Tomonaga developed renormalization theory in QED. The nuclear force is, of course, the basis of all nuclear physics. In this sense, Yukawa's work set the foundations for nuclear physics. Tomonaga worked in his late years on problems of collective motion appearing in many many-particle-systems, nuclear systems being one of the examples. Yukawa and Tomonaga were also deeply involved in founding the Institute of Fundamental Physics and Institute for Nuclear Study, through which they made invaluable contributions to the development of the field of nuclear physics. It is almost impossible to report in this short article on all of what they have achieved and thus I would like to discuss here their contributions to nuclear physics only in a limited scope, based on my personal reminiscence of them.

  18. Three-body forces: a status report

    International Nuclear Information System (INIS)

    Coon, S.A.

    1976-01-01

    Real three-body forces due to meson exchange are distinguished from effective three-body interactions of a nuclear Hamiltonian. The long-range part of the real three-body force is proportional to the off-mass-shell sup(PI)N scattering amplitude. Its contribution to the binding energy of nuclear matter is quite dependent upon the treatment of correlations (due to the two-body potential) in the three-body wave function. A recent improvemrnt in the amplitude implies a very small contribution. But, a recent improvement in the treatment of correlations implies a large contribution. Work towards including both these improvements in a single calculation is in progress. (author)

    This paper reports on the evolution of western nuclear capabilities. Presidents Truman and Eisenhower largely cast the die that determined the role, size, and organization of today's nuclear forces. The milestones were Truman's vast expansion of the nuclear weapons stockpile, followed by a series of seminal decisions by Eisenhower: transfer of peacetime civilian custody of nuclear weapons to the military; creation of a streamlined chain of command and a centrally coordinated war plan for all U.S. strategic forces; and the commitment to develop and deploy land- and submarine-based missiles of intercontinental range. The current U.S. strategic forces have some 11,000 widely dispersed nuclear warheads, of which more than 6,000 are ready for launch within minutes, can be traced back to these initiatives. Naturally, they were not taken in a geopolitical vacuum. Truman and Eisenhower had to contend with the Berlin Blockade in 1948, followed shortly thereafter by the Korean War

  20. Optimized reinforcement of nuclear power plant structures for aircraft impact forces

    International Nuclear Information System (INIS)

    1976-01-01

    Reactor buildings of nuclear power plants and, to some extent also other buildings of the plant, according to the present safety requirements, have to be able to withstand aircraft impact forces. The building has to withstand this loading only once since afterwards it will be out of use. Accordingly, other criteria for design and the necessary safety measures are valid than in the case of service loads. Large deformations and the development of large cracks due to such loadings are insignificant from a construction point of view for reinforced concrete structures i.e. the stresses can build up to the ultimate load carrying capacity. From the nuclear safety point of view, however, some restrictions are possible in this regard e.g. to obstruct the penetration of fuel through the cracks. Basically all mild steels, with large ducility and without brittle fracture under sudden load increase, are suitable for this purpose. High stresses in the structure would, however, require uneconomical concentrations of mild steel. It is for this reason that the use of high strength steels e.g. St 110/135, has been introduced in Germany for this kind of loading. Through the use of wire strands or cables of high strength steel it is possible to reach a condition of cracks and large deformations due to ultimate loads in zone of point loading. The reinforcement takes on a distinctly curved shape and is able to carry the normal loads and shears through a suspension-structure action. The deformability of the structure for the analysed limit load state can be further increased through a bond-free net. This measure allows a more uniform sketching of the cables or strands over a larger zone. (Auth.)

    2011-01-01

    In the twentieth century, race-based residential and commercial segregation that supported racial oppression and inequality became an elemental characteristic of urban black communities. Conflict-ridden, black-white relationships were common. However, the Chicago Defender Charities, Inc., the entity that sponsors the largest African American parade in the country and that emerged in 1947, embodied a tradition of charitable giving, self-help, and community service initiated in 1921 by Chicago Defender newspaper founder and editor, Robert S. Abbott. The foundation of this charitable tradition matured as a result of an early and sustained collaboration between Chicago’s white-owned Regal Theater and the black-owned Chicago Defender newspaper. Thus, in segregated African American communities, black and white commercial institutions, under certain conditions, were able to find important points of collaboration to uplift the African American communities of which they were a part.

    1984-01-01

    If continued construction on uncompleted nuclear plants causes Ohio and Michigan utility rates to jump anywhere from 44 to 97%, industry may flee the area and throw 54,000 people out of work, according to recent studies. At issue are the Midland 2 nuclear plant in Jackson, Michigan and the Zimmer Plant outside Cincinnati, which is scheduled to be converted to a coal-fired plant. Other factors would influence the job exodus, but higher power costs would have a major impact on area industries. Unemployment will also result when construction workers are no longer needed for the plants. Other areas of the country face similar power price increases. Both the Ohio and Michigan reports are based on power demand and cost projections

  7. A finite range pairing force for density functional theory in superfluid nuclei

    Tian, Y.; Ma, Z.Y.; Ring, P.

    2009-01-01

    The problem of pairing in the 1 S 0 channel of finite nuclei is revisited. In nuclear matter forces of separable form can be adjusted to the bare nuclear force, to any phenomenological pairing interaction such as the Gogny force or to exact solutions of the gap equation. In finite nuclei, because of translational invariance, such forces are no longer separable. Using well-known techniques of Talmi and Moshinsky we expand the matrix elements in a series of separable terms, which converges quickly preserving translational invariance and finite range. In this way the complicated problem of a cut-off at large momenta or energies inherent in other separable or zero range pairing forces is avoided. Applications in the framework of the relativistic Hartree-Bogoliubov approach show that the pairing properties are depicted on almost the same footing as by the original pairing interaction not only in nuclear matter, but also in finite nuclei. This simple separable force can be easily applied for the investigation of pairing properties in nuclei far from stability as well as for further investigations going beyond mean field theory.

  11. Implications of QCD for soft hadronic and nuclear processes

    International Nuclear Information System (INIS)

    1981-01-01

    Physical implications of QCD for strong forces in soft processes are discussed. Topics include long-range force, Van der Waals force, nuclear force, hadron and quark structures. In the absence of a reliable calculational scheme, phenomenological models have been built that incorporate QCD ideas as far as possible. In the framework of those models calculations have been made that provide an understanding of the soft processes in terms of quarks and gluons. We review recent work on nuclear potential, form factors at low Q 2 , pion decay constant, inclusive distribution of low p/sub T/, and radiation length of fast quark in nuclear matter

  12. Recent and prospective developments in nuclear arsenals

    International Nuclear Information System (INIS)

    Brown, M.

    1993-01-01

    Arms controllers have long complained that the only weapons states give up in arms control negotiations are strategically insignificant weapons. This is why the United States and Soviet Union shied away from giving up much in SALT I and SALT II: each side felt that it could not significantly reduce its nuclear forces, or take any step that might give the other side an advantage. Do not be fooled: policy makers in Washington and Moscow still believe that it is important to hang on to strategically significant weapons. But, because the world has changed in fundamental ways, fewer weapons are strategically significant today. Now that extended deterrence requirements have virtually disappeared, the main reason for having nuclear weapons is to deter other nuclear powers from attacking with their nuclear weapons. There is, therefore, no compelling reason for having large nuclear forces. Given concerns about unauthorized attacks, accidental launches, and high levels of defense spending, there are good reasons for deploying smaller forces. This is why Washington and Moscow have been cutting their nuclear arsenals to levels that were unimaginable even in 1990. How far this process will go is impossible to say at this juncture. What is clear is that Washington and Moscow can - and should - make even deeper cuts in their nuclear forces. If the United States and Russia retain arsenals with thousands of nuclear weapons, Britain, France, and China - whose arsenals contain hundreds of nuclear weapons - will not join the arms reduction process. Countries that have promised to give up the nuclear weapons currently stationed on their territory - Kazakhstan, the Ukraine, and Belorussia - will be more inclined to retain them, on the grounds that nuclear weapons are seen to have strategic and political value. For the same reasons, countries on the nuclear threshold, such as India, will be more inclined to acquire nuclear weapons. If the United States and Russia retain massive nuclear

    Madic, C.

    1997-01-01

    The separation of actinide elements from various waste materials, either produced in nuclear fuel cycle or in the past during nuclear weapon production, represent a significant issue facing developed countries. Improvements in the efficiencies of the separation processes can be expected from a better knowledge of the chemistry of these elements in these complex matrices. The Nuclear Science Committee of the OECD/NEA has established a task force of experts in actinide chemistry to review the current and developing separation techniques and chemical processes. Recommendations were made for future research and development programs. This article presents briefly the work of the Task Force which will be published soon as an OECD/NEA/NSC Report. (author)

  14. Theoretical studies in nuclear reactions and nuclear structure. Progress report

    Energy Technology Data Exchange (ETDEWEB)

    1992-05-01

    Research in the Maryland Nuclear Theory Group focusses on problems in four basic areas of current relevance. Hadrons in nuclear matter; the structure of hadrons; relativistic nuclear physics and heavy ion dynamics and related processes. The section on hadrons in nuclear matter groups together research items which are aimed at exploring ways in which the properties of nucleons and the mesons which play a role in the nuclear force are modified in the nuclear medium. A very interesting result has been the finding that QCD sum rules supply a new insight into the decrease of the nucleon`s mass in the nuclear medium. The quark condensate, which characterizes spontaneous chiral symmetry breaking of the late QCD vacuum, decreases in nuclear matter and this is responsible for the decrease of the nucleon`s mass. The section on the structure of hadrons contains progress reports on our research aimed at understanding the structure of the nucleon. Widely different approaches are being studied, e.g., lattice gauge calculations, QCD sum rules, quark-meson models with confinement and other hedgehog models. A major goal of this type of research is to develop appropriate links between nuclear physics and QCD. The section on relativistic nuclear physics represents our continuing interest in developing an appropriate relativistic framework for nuclear dynamics. A Lorentz-invariant description of the nuclear force suggests a similar decrease of the nucleon`s mass in the nuclear medium as has been found from QCD sum rules. Work in progress extends previous successes in elastic scattering to inelastic scattering of protons by nuclei. The section on heavy ion dynamics and related processes reports on research into the e{sup +}e{sup {minus}} problem and heavy ion dynamics.

    The Energy Reorganization Act of 1974 brought about markedly increased security requirements at nuclear power plants. NRC established a threat level against which the security forces were expected to defend. It is asserted that an inadequate legal basis exists for the NRC requirement that nuclear plants be defended by the use of deadly force, if necessary, and that complex issues such as apprehension, retention, and pursuit of intruders are left vague. Security measures patterned after the airline industry, resolution of the deadly force issue, and definition of a creditable threat level are proposed

    The problem of the non-proliferation of nuclear weapons is one of great concern today despite the entry into force in the early '70s of the NPT. To master civilian nuclear technology implies the ability to develop nuclear explosive devices; therefore in recent years contacts have strengthened between countries exporting nuclear equipment, specially in the frame of the 'London Club' so as to ensure that their exports will not result in disseminating nuclear weapons.

  17. The Sandys White Paper of 1957 and the move to the British new look. An analysis of nuclear weapons, conventional forces and strategic planning 1955-57

    Navias, Martin Stephen

    1989-01-01

    This study seeks to analyse the significance of the 1957 Defence White Paper in the context of British strategic planning during the mid-1950s. Claims that the White Paper represented a culmination of trends already prevalent in British defence planning are assessed while continuities and discontinuities in strategic policies are identified. This is done by highlighting the main features of the document and then tracing their development in the 1955-57 period. A major theme throughout is the relationship between the growing declaratory emphasis on nuclear deterrence and the determination of the shape and size of conventional forces and capabilities. It is contended that the defence decision making process that was in place prior to January 1957 was incapable of generating a British New Look - that is a consistent set of declaratory and action policies which reflected a cutback in conventional forces accompanied by a greater reliance on the threat of nuclear retaliation. Prior to Duncan Sandys becoming Minister of Defence, the inability of that ministry to readily impose itself on the service departments meant that the latter's attachment to preparations for global war and the national service programme could not be overruled. It is also unclear whether during the 1955-56 period the basis for a truly independent deterrent was being established. An analysis of the negotiations surrounding the 1957 White Paper indicates that Sandys was able to overrule traditional service preferences. The result was a policy which rejected the imposition of a conventional strategy on a nuclear one in favour of a British New Look. Consequently, conventional forces were reduced, greater relative importance was placed on the nuclear deterrent, but once more the requirements of a unilateral independent deterrent did not receive priority.

    On 8 May 2016, the Amendment to the Convention on the Physical Protection of Nuclear Material (CPPNM) finally entered into force, almost eleven years after its adoption. The world will be a more secure place as a result of the commitments that States party to the Amendment have made. The Amendment establishes legally binding commitments for countries to protect nuclear facilities as well as nuclear material in domestic use, storage and transport. Under the Amendment, countries are required to establish appropriate physical protection regimes for nuclear material. They also take on new obligations to share information on sabotage, including on credible threats of sabotage. The entry into force of the Amendment demonstrates the international community’s resolve to act together to strengthen nuclear security globally. It also helps reduce the risk of an attack involving nuclear material, which could have catastrophic consequences.

    1976-01-01

    We examine the feasibility of using the 2 H(p, pp) n reaction as a means of extracting information about the short-range behavior of the nuclear force not obtainable from N-N scattering experiments. To do this we use several separable potentials and examine the predicted cross section in various regions of phase space and for beam energies between 14 and 65 MeV. The questions that we address are likely to be insensitive to Coulomb effects. Both the form factor and the energy dependence of the potentials have been modified from the usual Yamaguchi form. The form of the energy dependence is chosen to obtain phase-shift equivalence for two different form factors while guaranteeing a unitary two-body scattering amplitude. The sensitivity of breakup results to the on-shell and off-shell aspects of the nuclear force is examined and discussed. Significant on-shell sensitivity occurs for breakup amplitudes in all states and for cross sections over all regions of phase space. Off-shell sensitivity appears only in the S = 1/2, L = 0 breakup amplitudes, with all S = 3/2 and all L > 0 amplitudes exhibiting negligible off-shell dependence. This result leads to only a very small (< or = 5%) off-shell sensitivity for quasifree scattering. However, cross sections far from quasifree scattering, and in particular cross sections in the final-state interaction region of phase space, exhibit as much as a 50% variation for phase-shift-equivalent potentials. This sensitivity is small at low beam energy and increases with increasing energy. The energy dependence at negative energies of one potential is also altered to adjust the triton binding energy. This enables us to compare phase-shift-equivalent potentials differing off shell but predicting the same triton binding energy. The energy dependence of this potential is somewhat unconventional. Fixing of the triton binding energy reduces the off-shell sensitivity appreciably only for E approximately-less-than 20 MeV

    Just as data from civilian trauma registries have been used to benchmark and evaluate civilian trauma care, data contained within the Joint Theater Trauma Registry (JTTR) present a unique opportunity to benchmark combat care. Using the iterative steps of the benchmarking process, we evaluated data in the JTTR for suitability and established benchmarks for 24-hour mortality in casualties with polytrauma and a moderate or severe blunt traumatic brain injury (TBI). Mortality at 24 hours was greatest in those with polytrauma and a severe blunt TBI. No mortality was seen in casualties with polytrauma and a moderate blunt TBI. Secondary insults after TBI, especially hypothermia and hypoxemia, increased the odds of 24-hour mortality. Data contained in the JTTR were found to be suitable for establishing benchmarks. JTTR data may be useful in establishing benchmarks for other outcomes and types of combat injuries.

    We have applied an economic model to the transfer of nuclear-power reactors from industrialized nations to the less developed nations. The model includes demand and supply factors and predicts the success of US nonproliferation positions and policies. We conclude that economic forces dominate the transfer of power reactors to less developed nations. Our study shows that attempts to either restrict or promote the spread of nuclear-power technology by ignoring natural economic incentives would have only limited effect. If US policy is too restrictive, less developed nations will seek other suppliers and thereby lower US Influence substantially. Allowing less developed nations to develop nuclear-power technology as dictated by economic forces will result in a modest rate of transfer that should comply with nuclear-proliferation objectives

    Is a nuclear power renaissance likely to occur in the United States? This paper investigates the many driving forces that will determine the answer to that question. This analysis reveals some frequently overlooked truths about the current state of nuclear technology: An examination of the issues also produces some noteworthy insights concerning government regulations and related technologies. Public opinion will play a major role in the unfolding story of the nuclear power renaissance. Some observers are betting that psychological, sociological, and political considerations will hod sway over public attitudes. Others wager that economic and technical concerns will prevail. The implications for the nuclear power renaissance are striking

    2011-01-01

    A prove of equations of motion for the nuclear shape variables which establish a direct connection of the memory effects with the dynamic distortion of the Fermi surface is suggested. The equations of motion for the nuclear Fermi liquid drop are derived from the collisional kinetic equation. In general, the corresponding equations are non-Markovian. The memory effects appear due to the Fermi surface distortions and depend on the relaxation time. The main purpose of the present work is to apply the non-Markovian dynamics to the description of the nuclear giant multipole resonances (GMR) and the large amplitude motion. We take also into consideration the random forces and concentrate on the formation of both the conservative and the friction forces to make more clear the memory effect on the nuclear dynamics. In this respect, the given approach represents an extension of the traditional liquid drop model (LDM) to the case of the nuclear Fermi liquid drop. In practical application, we pay close attention to the description of the descent of the nucleus from the fission barrier to the scission point.

    Unbiased stochastic sampling of the one- and two-body reduced density matrices is achieved in full configuration interaction quantum Monte Carlo with the introduction of a second, “replica” ensemble of walkers, whose population evolves in imaginary time independently from the first and which entails only modest additional computational overheads. The matrices obtained from this approach are shown to be representative of full configuration-interaction quality and hence provide a realistic opportunity to achieve high-quality results for a range of properties whose operators do not necessarily commute with the Hamiltonian. A density-matrix formulated quasi-variational energy estimator having been already proposed and investigated, the present work extends the scope of the theory to take in studies of analytic nuclear forces, molecular dipole moments, and polarisabilities, with extensive comparison to exact results where possible. These new results confirm the suitability of the sampling technique and, where sufficiently large basis sets are available, achieve close agreement with experimental values, expanding the scope of the method to new areas of investigation

    This paper presents a mathematical model that takes into account the bubble radius variation that take place in a boiling water nuclear reactor during transients with changes in the pressure vessel, changes in the inlet core mass flow rate, density-wave phenomena or flow regime instability. The model with expansion effects was developed considering the interaction force between a dilute dispersion of gas bubbles and a continuous liquid phase. The closure relationships were formulated as an associated problem with the spatial deviation around averaging variables as a function of known variables. In order to solve the closure problem, a geometric model given by an eccentric unit cell was applied as an approach of heterogeneous structure of the two-phase flow. The closure relationship includes additional terms that represent combined effects between translation and pulsation due to displacement and size variation of the bubbles, respectively. This result can be implanted straightforward in best estimate thermo-hydraulics models. An example, the implementation of the closure relationships into TRAC best estimate computer code is presented

    Of the permanent members of the UN Security Council, the United Kingdom has the smallest deterrent force, with fewer than 200 warheads and a single delivery system. Successive British governments policies for nuclear interdependence with the United States over the past 50 years have led to a growing technological dissymmetry with the Americans. This politico-strategic choice now considerably restricts Britain options for remaining a member of the club of nuclear powers into the future. (author)

    High-energy electron cooling, presently considered as an essential tool for several applications in high-energy and nuclear physics, requires an accurate description of the friction force which ions experience by passing through an electron beam. Present low-energy electron coolers can be used for a detailed study of the friction force. In addition, parameters of a low-energy cooler can be chosen in a manner to reproduce regimes expected in future high-energy operation. Here, we report a set of dedicated experiments in CELSIUS aimed at a detailed study of the magnetized friction force. Some results of the accurate comparison of experimental data with the friction force formulas are presented

    1998-01-01

    Since utilities and fuel venders have adopted the fuel design of high burn-up and improved thermal margin flow mixing vane, several PWR nuclear power plants have in recent years experienced fretting wear fuel rod failure due to flow induced vibration. Flow induced vibration can be resulted from fluidelastic instability, periodic shedding, turbulence-induced excitation, and acoustic resonance (1). Among these mechanisms found in the core of nuclear power plant, the governing mechanism that is fluidelastic instability, could be inferred from the analysis of fuel failure patterns. Therefore, to simulate the fuel failure in nuclear power plants, Tanaka's model (2) was chosen as most suitable one, which is well explaining the damage pattern, in particular it's second row damage characteristics. In the model, unsteady fluid dynamic forces acting on the vibrating cyclinders were included which consists of the inertia forces due to the added mass of fluid, damping forces of fluid in phase to the cylinder vibrating velocity, and stiffness forces proportional to cylinder displacements. However, the model did not account for radiation effect-spring forces deflection. So, the model was modified to account for the spring force relaxation due to radiation exposure. The stiffness of spring was fitted with experimental data. Finally the critical velocities were calculated with the modified spring force at beginning and end of cycle

    The cell nucleus is the largest and stiffest organelle rendering it the limiting compartment during migration of invasive tumor cells through dense connective tissue. We here describe a combined atomic force microscopy (AFM)-confocal microscopy approach for measurement of bulk nuclear stiffness together with simultaneous visualization of the cantilever-nucleus contact and the fate of the cell. Using cantilevers functionalized with either tips or beads and spring constants ranging from 0.06-10 N m-1, force-deformation curves were generated from nuclear positions of adherent HT1080 fibrosarcoma cell populations at unchallenged integrity, and a nuclear stiffness range of 0.2 to 2.5 kPa was identified depending on cantilever type and the use of extended fitting models. Chromatin-decondensating agent trichostatin A (TSA) induced nuclear softening of up to 50%, demonstrating the feasibility of our approach. Finally, using a stiff bead-functionalized cantilever pushing at maximal system-intrinsic force, the nucleus was deformed to 20% of its original height which after TSA treatment reduced further to 5% remaining height confirming chromatin organization as an important determinant of nuclear stiffness. Thus, combined AFM-confocal microscopy is a feasible approach to study nuclear compressibility to complement concepts of limiting nuclear deformation in cancer cell invasion and other biological processes.

    The well-know 1980 joke, according to which the Soviet Union was nothing else than Upper Volta armed with nuclear missiles, was literally not quite correct. On top of its nuclear missiles, the former Soviet Union had a lot of nuclear and conventional submarines, combat aircraft, tanks and other deadly weaponry. Yet it was true that the global ambitions of the high military commanders, the captains of the Soviet military-industrial complex, and the CPSU chiefs burdened the weak Soviet economy. In fact, military related expenditures, mounting up to 25 percent of the USSR GDP, were among the most fundamental causes of the Soviet economic and political collapse. By the 1990, the joke had become even more credible. Yeltzin Russia, affected by severe economic and social crises, kept only two attributes of its former superpower status: a seat on the UN Security Council and a substantial yet decreasing nuclear arsenal. Russia recent economic revival and political transformation, from the embryonic and chaotic democracy of Yeltzin into an authoritarian regime pillaring itself on the security sector and the post-Soviet bureaucracy, provoke critical questions in regards to the nation future role in the emerging international system, primarily in the Eurasian region. Two of these questions are whether Russia will be able to maintain the world second largest strategic nuclear arsenal, and how Russia ruling class will view the roles and missions of nuclear weapons. To answer these questions it is necessary to assess (a) the governmental policy that determines the development of Russian nuclear force; (b) the structure and quantity of the current nuclear force; and (c) the capacity of missile and submarine-building industries.

    1979-01-01

    An approach to a unified description of nuclear reactions and nuclear structure based on the formalism of the quantum Green functions and on the ideas of the theory of finite Fermi systems has been formulated. New structural vertices are introduced, which are responsible for nucleon collectivization in an atomic nucleus and for the excitation of many-phonon, quasideuteron, quasitriton and other configurations. The vertices define both the processes of particle scattering by atomic nuclei (T matrix and optical potentials) and the nuclear structure (secular equations and wave functions). The vertices are determined from the equations with effective many-particle forces Fsub(nm)sup(c). In their turn the Fsub(nm)sup(c) forces are either determined from a comparison of theory and experiment, or calculated from the equations with more fundamental nucleon-nucleon forces in a nucleus. The effective forces Fsub(nm)sup(c) are more universal than the constants of the theory of finite Fermi-systems, which extends the boundaries of applicability of the particle-hole formalism in the description of nuclear processes. In this approach the traditional methods of description of the nuclear structure, based on particular models of hamiltonian and wave functions, acquire a natural interpretation

    The Department of Energy's Nuclear Physics program is a comprehensive program of interdependent experimental and theoretical investigation of atomic nuclei. Long range goals are an understanding of the interactions, properties, and structures of atomic nuclei and nuclear matter at the most elementary level possible and an understanding of the fundamental forces of nature by using nuclei as a proving ground. Basic ingredients of the program are talented and imaginative scientists and a diversity of facilities to provide the variety of probes, instruments, and computational equipment needed for modern nuclear research. Approximately 80% of the total Federal support of basic nuclear research is provided through the Nuclear Physics program; almost all of the remaining 20% is provided by the National Science Foundation. Thus, the Department of Energy (DOE) has a unique responsibility for this important area of basic science and its role in high technology. Experimental and theoretical investigations are leading us to conclude that a new level of understanding of atomic nuclei is achievable. This optimism arises from evidence that: (1) the mesons, protons, and neutrons which are inside nuclei are themselves composed of quarks and gluons and (2) quantum chromodynamics can be developed into a theory which both describes correctly the interaction among quarks and gluons and is also an exact theory of the strong nuclear force. These concepts are important drivers of the Nuclear Physics program

These techniques are useful methods allowing direct observation of surface morphologies. Particularly in the nuclear track fields, they offer a new tool to give many new informations on track formation. In this paper we present the preliminary results of a new use of this technique to characterize continuously the formation of the revealed track in a cellulose nitrate detector (LR115) after an alpha particle irradiation. For that, a specific cell has been used to observe, by nano-observations, the evolution of track shapes simultaneously with chemical treatment. Thus, the track shape evolution has been studied; visualizing the evolution of the tracks in real time, in situ during the chemical etching process.

  9. Find and neutralize clandestine nuclear weapons

    The objective of finding nuclear material at entry portals is to provide a secure perimeter as large as a weapon damage radius so that operations could be conducted within it relatively unencumbered. The objective of wide area search for nuclear material to provide a safe zone of similar dimensions in an area in which it is not possible to maintain a secure perimeter, to provide assurance for civilians living at an area at risk, or to provide rapid, wide area search of regions that could conceal nuclear threats to forces in the field. This rapid, wide-area, and confident detection of nuclear materials is the essential first step in developing the ability to negate terrorist nuclear assemblies or weapons. The ability to detect and negate nuclear materials are necessary to prevent the forced, massive evacuation of urban populations or the disruption of military operations in response to terrorist threats. This paper describes the limitations to current sensors used for nuclear weapon detection and discusses a novel approach to nuclear weapon detection using a combination of directional information (imaging) and gamma ray energy (color) to produce a gamma ray color camera

  10. Nuclear forces and quark degrees of freedom

    Attempts to derive the NN forces from the quark and gluon degrees of freedom have been made so far in the framework of the nonrelativistic quark-cluster model (QCM). The justification of such a model is based on the remarkable success in describing the static properties of single hadrons. In the earlier calculations, the NN s-wave phase shifts obtained with the QCM show that the model produces repulsive NN forces at short distances, which constitutes a success for the model, but fails to provide the intermediate range attraction indispensable for binding nucleons in nuclei. This drawback is amended within the context of these models, at the expense of introducing by hand intermediate-range attraction through meson-exchange potentials between quarks or/and between nucleons (quark clusters). This procedure improves the results for the phase shifts and it is often concluded that the QCM provides a good description of the short-range (SR) part of the NN potential. In our opinion, the above procedure does not provide a rigorous test of the validity of the quark-cluster model. In order to get a clear-cut conclusion one should consider the QCM in association with an accurate and well founded model for the long-medium-range (LR+MR) forces. For these reason we study a NN interaction model which satisfies this requirement. In this model, the LR+MR parts are given by the Paris NN potential and the SR part by the QCM. The quality of the model is then tested by confronting directly its predictions with data on observables rather then, as it is usually done, with phase shifts. We compute all the observables for pp and np scattering at energies below the pion production threshold for different QCM versions corresponding to different qq interactions. The results are then compared with the existing world set data. Preliminary results show that the agreement with experiment is not good. (authors)

    This paper reports on the conventional wisdom which is that if Warsaw Pact forces attacked NATO they would probably win the war in a few weeks unless NATO used battlefield nuclear weapons to stop the advancing Warsaw Pact forces. This means, of course, also the risk of having to use nuclear weapons on West German territory; this use would inevitably result in the death of a large number of West German civilians and great damage to property. The cost to NATO in death and collateral damage of using battlefield nuclear weapons would be so high as to make this use incredible

  12. Applications of nuclear safety probabilistic risk assessment to nuclear security for optimized risk mitigation

    2016-06-15

    Critical infrastructure assets such as nuclear power generating stations are potential targets for malevolent acts. Probabilistic methodologies can be applied to evaluate the real-time security risk based upon intelligence and threat levels. By employing this approach, the application of security forces and other protective measures can be optimized. Existing probabilistic safety analysis (PSA) methodologies and tools employed. in the nuclear industry can be adapted to security applications for this purpose. Existing PSA models can also be adapted and enhanced to consider total plant risk, due to nuclear safety risks as well as security risks. By creating a Probabilistic Security Model (PSM), safety and security practitioners can maximize the safety and security of the plant while minimizing the significant costs associated with security upgrades and security forces.

    2014-01-01

    After a temporary halt following the Fukushima nuclear disaster in March 2011, China resumed its fast, yet cautious, expansion of nuclear energy programme. Nuclear energy is considered as part of the general strategy to deal with the challenges of energy security and climate change and to advance with ‘state of the art’ technology in its development. This article briefly discusses recent development in and driving forces behind nuclear industry in China, and several challenges it has been facing: how to adopt, adapt, standardise and indigenise whose technologies, and how to address the shortage of qualified nuclear engineers, scientists, skilled labour force and qualified regulators. More importantly, it argues that safe and secure nuclear development requires consistent policies and effective regulations. Therefore, it is crucial to build policy and regulatory capacities based on coordination, planning and management of government agencies and the industry. - Highlights: • Nuclear energy development in China. • Nuclear technology selection. • Human capital. • Regulatory regime. • Safe and secure development

    Stewart-Parker, Emma; Galloway, Robert; Vig, Stella

    Possessing adequate nontechnical skills (NTS) in operating theaters is of increasing interest to health care professionals, yet these are rarely formally taught. Teams make human errors despite technical expertise and knowledge, compromising patient safety. We designed a 1-day, multiprofessional, multidisciplinary course to teach, practice, and apply these skills through simulation. The course, "S-TEAMS," comprised a morning of lectures, case studies, and interactive teamworking exercises. The afternoon divided the group into multiprofessional teams to rotate around simulated scenarios. During the scenarios, teams were encouraged to focus on NTS, including communication strategies, situational awareness, and prompts such as checklists. A thorough debrief with experienced clinician observers followed. Data was collected through self-assessments, immediate and 6-month feedback to assess whether skills continued to be used and their effect on safety. In total, 68 health care professionals have completed the course thus far. All participants felt the course had a clear structure and that learning objectives were explicit. Overall, 95% felt the scenarios had good or excellent relevance to clinical practice. Self-assessments revealed a 55% increase in confidence for "speaking up" in difficult situations. Long-term data revealed 97% of the participants continued to use the skills, with 88% feeling the course had prevented them from making errors. Moreover, 94% felt the course had directly improved patient safety. There is a real demand and enthusiasm for developing NTS within the modern theater team. The simple and easily reproducible format of S-TEAMS is sustainable and inclusive, and crucially, the skills taught continue to be used in long term to improve patient safety and teamworking.

  19. Superpower nuclear minimalism

    Energy Technology Data Exchange (ETDEWEB)

    Graben, E.K.

    1992-01-01

    During the Cold War, the United States and the Soviet Union competed in building weapons -- now it seems like America and Russia are competing to get rid of them the fastest. The lengthy process of formal arms control has been replaced by exchanges of unilateral force reductions and proposals for reciprocal reductions not necessarily codified by treaty. Should superpower nuclear strategies change along with force postures President Bush has yet to make a formal pronouncement on post-Cold War American nuclear strategy, and it is uncertain if the Soviet/Russian doctrine of reasonable sufficiency formulated in the Gorbachev era actually heralds a change in strategy. Some of the provisions in the most recent round of unilateral proposals put forth by Presidents Bush and Yeltsin in January 1992 are compatible with a change in strategy. Whether such a change has actually occurred remains to be seen. With the end of the Cold War and the breakup of the Soviet Union, the strategic environment has fundamentally changed, so it would seem logical to reexamine strategy as well. There are two main schools of nuclear strategic thought: a maximalist school, mutual assured destruction (MAD) which emphasizes counterforce superiority and nuclear war- fighting capability, and a MAD-plus school, which emphasizes survivability of an assured destruction capability along with the ability to deliver small, limited nuclear attacks in the event that conflict occurs. The MAD-plus strategy is based on an attempt to conventionalize nuclear weapons which is unrealistic.

  20. Nuclear fuel element

    1978-01-01

    A nuclear fuel element comprises an elongated tube having upper and lower end plugs fixed to both ends thereof and nuclear fuel pellets contained within the tube. The fuel pellets are held against the lower end plug by a spring which is supported by a setting structure. The setting structure is maintained at a proper position at the middle of the tube by a wedge effect caused by spring force exerted by the spring against a set of balls coacting with a tapered member of the setting structure thereby wedging the balls against the inner wall of the tube, and the setting structure is moved free by pushing with a push bar against the spring force so as to release the wedge effect

  1. Noise exposure in movie theaters: a preliminary study of sound levels during the showing of 25 films.

    2010-09-01

    The harmful effects of noise exposure during leisure-time activities are beginning to receive some scrutiny. We conducted a preliminary study to investigate the noise levels during the showings of 25 different films. During each screening, various sound measurements were made with a dosimeter. The movies were classified on the basis of both their Motion Picture Association of America (MPAA) rating and their genre, and the size of the theater and the size of the audience were taken into consideration in the final analysis. Our findings suggest that the sound levels of many movies might be harmful to hearing, although we can draw no definitive conclusions. We did not discern any relationship between noise levels and either MPAA rating or genre. Further studies are recommended.

  2. The future of U.S.-Russia nuclear arms control

    Pifer, Steven

    2017-11-01

    Nuclear arms control has long made contributions to U.S.-Soviet and U.S.-Russian security, but the current regime is at risk. The 1987 Intermediate-range Nuclear Forces Treaty may be headed for collapse. Both the United States and Russia are modernizing their strategic forces, and the fate of the 2010 New Strategic Arms Reduction Treaty is unclear. In the unlikely case that the sides are prepared to go beyond New START, there are ways to address further reductions and related issues. A collapse of the arms control regime, on the other hand, would mean the end of constraints on U.S. and Russian nuclear forces, a significant loss of transparency, and potential costs to U.S. security.

    A density-dependent effective potential for the baryon–baryon interaction in the presence of the (hyper)nuclear medium is constructed, based on the leading (irreducible) three-baryon forces derived within SU(3) chiral effective field theory. We evaluate the contributions from three classes: contact terms, one-pion exchange and two-pion exchange. In the strangeness-zero sector we recover the known result for the in-medium nucleon–nucleon interaction. Explicit expressions for the ΛN in-medium potential in (asymmetric) nuclear matter are presented. Our results are suitable for implementation into calculations of (hyper)nuclear matter. In order to estimate the low-energy constants of the leading three-baryon forces we introduce the decuplet baryons as explicit degrees of freedom and construct the relevant terms in the minimal non-relativistic Lagrangian. With these, the constants are estimated through decuplet saturation. Utilizing this approximation we provide numerical results for the effect of the three-body force in symmetric nuclear matter and pure neutron matter on the ΛN interaction. A moderate repulsion that increases with density is found in comparison to the free ΛN interaction.

  5. Exploring domestic violence and social distress in Australian-Indian migrants through community theater.

    In many parts of the world, young adult women have higher levels of common mental disorders than men. The exacerbation of domestic violence (DV) by migration is a salient social determinant of poor mental health. Ecological models describe factors contributing to DV as operating at individual, family, cultural, and societal levels. We explored the interplay among these factors in an Indian community living in Melbourne, Australia, in a qualitative participatory action research study using a modified Forum Theater approach. We here present findings on connections between migration, societal factors, and social/family/cultural factors in DV. The study captured the voices of women living in the community as they describe how DV contributes to their emotional difficulties. Improved understanding of the sociocultural dynamics of DV and the associated social distress in this migrant Indian community can be used to guide the development of culturally sensitive prevention and response programs to assist migrant women from the Indian subcontinent who present with psychopathology and suicidal behaviors associated with DV. © The Author(s) 2015.

  6. Tourniquets and exsanguinators: a potential source of infection in the orthopedic operating theater?

    LENUS (Irish Health Repository)

    Brennan, Stephen A

    2009-04-01

    BACKGROUND AND PURPOSE: Fomites are increasingly being recognised as a source of hospital-acquired infection. We have therefore assessed tourniquets and exsanguinators for the presence of bacterial pathogens in 1 elective and 2 trauma orthopedic hospitals. MATERIAL AND METHODS: Swabs were taken prior to and after decontaminating these devices with 1 of 3 different cleaning modalities. These were then assessed for colony counts and organisms identified. RESULTS: Bacteria commonly implicated in surgical site infections such as coagulase-negative staphylococci, Staphylococcus aureus and Proteus spp. were prevalent. We also found a resistant strain of Acinetobacter and Candida. Exsanguinators were the most heavily contaminated devices, and colony counts in the trauma hospitals were up to 400% higher than in the elective hospital. Alcohol- and non-alcohol-based sterile wipes were both highly effective in decontaminating the devices. INTERPRETATION: Infectious organisms reside on the tourniquets and exsanguinators presently used in the orthopedic theater. These fomites may possibly be a source of surgical site infection. We have demonstrated a simple and effective means of decontaminating these devices between cases.

    1983-01-01

    Economics and the futility of arms competition with the US and USSR has forced China to shift its nuclear effort to peaceful uses, although its current nuclear-deterrent warrants including China in arms negotiations. China's nuclear program began during the 1950s with an emphasis on weaponry and some development in space technology. Proponents of nuclear power now appear to have refuted the earlier arguments that nuclear-plant construction would be too slow, too dangerous and polluting, and too expensive and the idea that hydro resources would be adequate. The current leadership supports a serious nuclear-power-plant construction program. 6 references

  13. Nuclear movement in fungi.

    Science.gov (United States)

    Xiang, Xin

    2017-12-11

    Nuclear movement within a cell occurs in a variety of eukaryotic organisms including yeasts and filamentous fungi. Fungal molecular genetic studies identified the minus-end-directed microtubule motor cytoplasmic dynein as a critical protein for nuclear movement or orientation of the mitotic spindle contained in the nucleus. Studies in the budding yeast first indicated that dynein anchored at the cortex via its anchoring protein Num1 exerts pulling force on an astral microtubule to orient the anaphase spindle across the mother-daughter axis before nuclear division. Prior to anaphase, myosin V interacts with the plus end of an astral microtubule via Kar9-Bim1/EB1 and pulls the plus end along the actin cables to move the nucleus/spindle close to the bud neck. In addition, pushing or pulling forces generated from cortex-linked polymerization or depolymerization of microtubules drive nuclear movements in yeasts and possibly also in filamentous fungi. In filamentous fungi, multiple nuclei within a hyphal segment undergo dynein-dependent back-and-forth movements and their positioning is also influenced by cytoplasmic streaming toward the hyphal tip. In addition, nuclear movement occurs at various stages of fungal development and fungal infection of plant tissues. This review discusses our current understanding on the mechanisms of nuclear movement in fungal organisms, the importance of nuclear positioning and the regulatory strategies that ensure the proper positioning of nucleus/spindle.

    1979-01-01

    Experiments are described in which an enhanced nuclear system is used as a precoolant for a nuclear demagnetisation stage. The results show the promising advantages of such a system in those circumstances for which a large cooling power is required at extremely low temperatures. A theoretical review of nuclear enhancement at the microscopic level and its macroscopic thermodynamical consequences is given. The experimental equipment for the implementation of the nuclear enhanced refrigeration method is described and the experiments on two-stage nuclear demagnetisation are discussed. With the nuclear enhanced system PrCu 6 the author could precool a nuclear stage of indium in a magnetic field of 6 T down to temperatures below 10 mK; this resulted in temperature below 1 mK after demagnetisation of the indium. It is demonstrated that the interaction energy between the nuclear moments in an enhanced nuclear system can exceed the nuclear dipolar interaction. Several experiments are described on pulsed nuclear magnetic resonance, as utilised for thermometry purposes. It is shown that platinum NMR-thermometry gives very satisfactory results around 1 mK. The results of experiments on nuclear orientation of radioactive nuclei, e.g. the brute force polarisation of 95 NbPt and 60 CoCu, are presented, some of which are of major importance for the thermometry in the milli-Kelvin region.

    1984-01-01

    A remotely maintainable force-reflecting servomanipulator concept is being developed at the Oak Ridge National Laboratory as part of the Consolidated Fuel Reprocessing Program. This new manipulator addresses requirements of advanced nuclear fuel reprocessing with emphasis on force reflection, remote maintainability, reliability, radiation tolerance, and corrosion resistance. The advanced servomanipulator is uniquely subdivided into remotely replaceable modules which will permit in situ manipulator repair by spare module replacement. Manipulator modularization and increased reliability are accomplished through a force transmission system that uses gears and torque tubes. Digital control algorithms and mechanical precision are used to offset the increased backlash, friction, and inertia resulting from the gear drives. This results in the first remotely maintainable force-reflecting servomanipulator in the world. 10 references, 4 figures, 1 table

  19. Strategic forces: Future requirements and options

    Energy Technology Data Exchange (ETDEWEB)

    Speed, R.D.

    1990-11-01

    In the wake of the collapse of the Warsaw Pact and the apparent ending of the Cold War, there have been renewed calls for radical cuts in US strategic forces to levels far below the 10,000 or so warheads allowed each side under the current START proposal. Since it now appears that NATO for the first time will have the capability to defeat a Soviet conventional attack without the necessity of threatening to resort to nuclear weapons, this should pave the way for the rethinking of US strategy and the reduction of US strategic weapons requirements. In this new environment, it seems plausible that, with a modification of the Flexible Response doctrine to forego attempts to disarm the Soviet Union, deterrence could be maintained with 1500 or so survivable strategic weapons. With a new strategy that confined US strategic weapons to the role of deterring the use of nuclear weapons by other countries, a survivable force of about 500 weapons would seem sufficient. With this premise, the implications for the US strategic force structure are examined for two cases: a treaty that allows each side 3000 warheads and one that allows each side 1000 warheads.

  1. Three-body forces, relativistic effects, isobars, and pions in nuclear systems

    International Nuclear Information System (INIS)

    Wiringa, R.B.

    1983-01-01

    Conventional microscopic calculations in nuclear physics start from a nonrelativistic Hamiltonian. The many-body Schroedinger equation is then solved to obtain the ground state energy, wave function, and expectation values of other quantities of interest. Such a procedure gives a qualitative description of nuclear saturation properties, but it is now well established that the simple H is quantitatively inadequate. For example, the light nuclei are underbound with too large a charge radius, while nuclear matter is overbound at far too high a density. This note reviews recent studies that go beyond the simple H. These include 1) the introduction of three-nucleon potentials, 2) estimates of relativistic effects, 3) the introduction of isobar degrees of freedom in the two-body potential, and 4) probing the influence of pion degrees of freedom on nuclear systems

    Nuclei and nuclear reactions offer a unique setting for investigating three (and in some cases even all four) of the fundamental forces in nature. Nuclei have been shown – mainly by performing scattering experiments with electrons, muons, and neutrinos – to be extended objects with complex internal structures: constituent quarks; gluons, whose exchange binds the quarks together; sea-quarks, the ubiquitous virtual quark-antiquark pairs and, last but not least, clouds of virtual mesons, surrounding an inner nuclear region, their exchange being the source of the nucleon-nucleon interaction.   The interplay between the (mostly attractive) hadronic nucleon-nucleon interaction and the repulsive Coulomb force is responsible for the existence of nuclei; their degree of stability, expressed in the details and limits of the chart of nuclides; their rich structure and the variety of their interactions. Despite the impressive successes of the classical nuclear models and of ab-initio approaches, there is clearly no ...

  5. Keeping the LINC: the importance of nucleocytoskeletal coupling in intracellular force transmission and cellular function.

    Providing a stable physical connection between the nucleus and the cytoskeleton is essential for a wide range of cellular functions and it could also participate in mechanosensing by transmitting intra- and extra-cellular mechanical stimuli via the cytoskeleton to the nucleus. Nesprins and SUN proteins, located at the nuclear envelope, form the LINC (linker of nucleoskeleton and cytoskeleton) complex that connects the nucleus to the cytoskeleton; underlying nuclear lamins contribute to anchoring LINC complex components at the nuclear envelope. Disruption of the LINC complex or loss of lamins can result in disturbed perinuclear actin and intermediate filament networks and causes severe functional defects, including impaired nuclear positioning, cell polarization and cell motility. Recent studies have identified the LINC complex as the major force-transmitting element at the nuclear envelope and suggest that many of the aforementioned defects can be attributed to disturbed force transmission between the nucleus and the cytoskeleton. Thus mutations in nesprins, SUN proteins or lamins, which have been linked to muscular dystrophies and cardiomyopathies, may weaken or completely eliminate LINC complex function at the nuclear envelope and result in impaired intracellular force transmission, thereby disrupting critical cellular functions.

    Well depth parameter S or range correction factor S-1 is computed for several nuclear potentials such as square, Gaussian, exponential and Yukawa wells. A simple central force is assumed for nuclear potential between nucleons. We adopted only two parameters for potentials and attempted to clarify the fundamental nature of the nuclear forces that bind a proton and a neutron into a deuteron. Results thus obtained were used for an estimate of first order correction to simple square well model. (Author)

    Davies, K.T.R.; Managan, R.A.; Nix, J.R.; Sierk, A.J.

    1977-01-01

    We introduce a degree of freedom to describe the rupture of the neck in nuclear fission and calculate the point at which the neck ruptures as the nucleus descends dynamically from its fission saddle point. This is done by mentally slicing the system into two portions at its minimum neck radius and calculating the force required to separate the two portions while keeping their shapes fixed. This force is obtained by differentiating with respect to separation the sum of the Coulomb and nuclear interaction energies between the two portions. For nuclei throughout the Periodic Table we calculate this force along dynamical paths leading from the fission saddle point. The force is initially attractive but becomes repulsive when the neck reaches a critical size. For actinide nuclei the neck radius at which rupture occurs is about 2 fm. This increases the calculated translational kinetic energy of the fission fragments at infinity relative to that calculated for scission occurring at zero neck radius. With the effect of neck rupture taken into account, we calculate and compare with experimental results fission-fragment kinetic energies for two types of nuclear dissipation: ordinary two-body viscosity and one-body dissipation

    The Skyrme force is a zero-range force that allows the construction of the mean field inside the nucleus in a simple way. Skyrme forces are reasonably predictive but some features of the infinite nuclear matter or the mass of heavy nuclei are not well computed. The aim of this work is to propose an expanded parametrization of the Skyrme force in order to improve its predictive power. The first part is dedicated to the construction of the expansion of the parametrization. We recall how the effective forces are linked to the nucleon-nucleon interaction then we show the limits of the standard Skyrme forces and we propose a relatively natural improvements based on the integration of spin and isospin instabilities. The second part deals with the validation of the model, first by describing infinite nuclear matter then by studying β-balanced nuclear matter which has enabled us to reproduce some features of neutron stars like mass and radius. The computation of properties of nuclei like binding energy, mass, radii depends strongly on the adjustment procedure. (A.C.)

    A dynamic simulation of a security force-adversary engagement has been developed to obtain a better understanding of the complexities involved in security systems. Factors affecting engagement outcomes were identified and interrelated to represent an ambush of an escorted nuclear fuel truck convoy by an adversary group. Other forms of engagement such as assault and skirmish also can be simulated through suitable parameter changes. The dynamic model can provide a relative evaluation of changes in security force levels, equipment, training, and tactics. Continued application and subsequent refinements of the model are expected to augment the understanding of component interaction within a guard-based security system

  17. Relativistic quasiparticle random phase approximation with a separable pairing force

    International Nuclear Information System (INIS)

    Tian Yuan; Ma Zhongyu; Ring Peter

    2009-01-01

    In our previous work, we introduced a separable pairing force for relativistic Hartree-Bogoliubov calculations. This force was adjusted to reproduce the pairing properties of the Gogny force in nuclear matter. By using the well known techniques of Talmi and Moshinsky it can be expanded in a series of separable terms and converges quickly after a few terms. It was found that the pairing properties can be depicted on almost the same footing as the original pairing interaction, not only in nuclear matter, but also in finite nuclei. In this study, we construct a relativistic quasiparticle random phase approximation (RQRPA) with this separable pairing interaction and calculate the excitation energies of the first excited 2 + states and reduced B(E2; 0 + →2 + ) transition rates for a chain of Sn isotopes in RQRPA. Compared with the results of the full Gogny force, we find that this simple separable pairing interaction can describe the pairing properties of the excited vibrational states as well as the original pairing interaction.

    The objective of this study was to develop force-time impact signature data for use in the design or evaluation of nuclear power plant structures subject to tornado-borne automotive vehicle impact. The approach was based on the use of analytical vehicle models to calculate imact forces. To assess the significance of vehicle/structure interaction for head-on impact force-histories, a lumped-mass model of a reinforced concrete wall panel was coupled to a one-dimensional vehicle model for numerous panel design configurations within the range of practical interest. Vehicle-structure interaction was found to have relatively little effect on the force histories

    Two force reconstruction techniques were used to evaluate the slapdown response of a 1/3 scale model solid steel, spent fuel cask dropped 30 ft onto an unyielding target. The two techniques are: the sum of weighted acceleration technique (SWAT) and the deconvolution technique (DECON). A brief description and the calibration of the techniques as applied to the cask are presented. For the slapdown test, both techniques yielded very similar resultant forces and provided more accurate definition of the force-time history for the cask than is available from conventional data reduction methods. An applied moment, a measurement previously unobtainable from conventional cask accelerometer data reduction techniques, was determined with SWAT. The angular velocity calculated with SWAT was verified with photometric measurements. 9 refs., 22 figs

    1975-01-01

    The legal regime in force before entry into force of the 1971 Brussels Convention relating to civil liability for the maritime carriage of nuclear material created serious difficulties for maritime carriers, regarding both the financial risks entailed and restrictions on enjoyment of the rights granted by civil liability conventions. The 1971 Convention exonerates from liability any person likely to be held liable for nuclear damage under maritime law, provided another person is liable under the nuclear conventions or an equivalent national law. A problem remaining is that of compensation of nuclear damage to the means of transport for countries not having opted for re-inclusion of such damage in the nuclear law regime; this does not apply however to countries having ratified the Convention to date. A feature of the latter is that it establishes as extensively as possible the priority of nuclear law over maritime law. Furthermore the new regime continues to preserve efficiently the interests of victims of nuclear incidents. It is therefore to be hoped that insurers will no longer hesitate to cover international maritime carriage of nuclear material [fr

    Catudal, H.M.

    1989-01-01

    This book examines the nature of the Soviet nuclear threat and how it has evolved over the years. Too often in the past U.S. officials, in shaping and directing plans for American nuclear forces, have tended to see Soviet military forces and strategy as a reflection of their own stance or simply as projecting the worst plausible case of Soviet intentions and capabilities. The result has been a distorted if not dangerous portrayal of the real threat. Soviet nuclear strategy, as explained in this detailed book, has evolved significantly since the days when the Soviets first possessed nuclear weapons under Joseph Stalin. Today there is in development a new Soviet military and strategic doctrine reflected in Gorbachev's words, We require a radical break with traditions of political thinking. This new doctrine promises to have a profound impact on European security and the overall East-West relationship

    ABSTRACT Nuclear positioning is a crucial cell function, but how a migrating cell positions its nucleus is not understood. Using traction-force microscopy, we found that the position of the nucleus in migrating fibroblasts closely coincided with the center point of the traction-force balance, called the point of maximum tension (PMT). Positioning of the nucleus close to the PMT required nucleus–cytoskeleton connections through linker of nucleoskeleton-to-cytoskeleton (LINC) complexes. Although the nucleus briefly lagged behind the PMT following spontaneous detachment of the uropod during migration, the nucleus quickly repositioned to the PMT within a few minutes. Moreover, traction-generating spontaneous protrusions deformed the nearby nucleus surface to pull the nuclear centroid toward the new PMT, and subsequent retraction of these protrusions relaxed the nuclear deformation and restored the nucleus to its original position. We propose that the protruding or retracting cell boundary transmits a force to the surface of the nucleus through the intervening cytoskeletal network connected by the LINC complexes, and that these forces help to position the nucleus centrally and allow the nucleus to efficiently propagate traction forces across the length of the cell during migration.

  14. Coriolis force and nuclear deformation: cadmium and lead isotopes results with the EUROBALL gamma multidetector

    International Nuclear Information System (INIS)

    2001-01-01

    This work is devoted to the study of the nuclear matter at high rotational frequency. Thanks to the new generation of γ-ray multidetector array, as EUROGAM then EUROBALL, we propose to identify two sorts of nuclei belonging to two different mass region. Their identification is based on the detection of their γ-rays of des-excitation. We will follow the evolution of the influence of the Coriolis force at the microscopic scale. The cadmium nuclei 113-116 Cd have been populated using heavy-ion induced fission reaction ( 28 Si+ 176 Yb at 145 MeV). Decoupled bands have been identified in odd-nuclei, produced for the first time at high spin. As they were considered as the best example of vibrational nuclei during their studies by radioactivity, they exhibit a small prolate deformation, confirmed by our microscopic calculations performed for even-even nuclei. The odd superdeformed nucleus 197 Pb have been studied via a fusion-evaporation reaction ( 18 O+ 186 W at 117 MeV). We have established the cross-talk transitions between the two signature partners. The experimental measurement of the branching ratio B(M1)/B(E2) allows us to extract the magnetic properties of the superdeformed matter, conforming the lack of quenching for the neutrons. The Coriolis force depends on the nuclei deformation and on the individual configuration. In cadmium nuclei, the single neutron νh 11/2 , Ω=1/2 is decoupled from the motion of the core, whereas in superdeformed nuclei, the Coriolis effect is much weaker on the νj 15/2 , Ω = 5/2 neutron.

    In view of the fact that the regulation of maritime transport of nuclear materials comes under both maritime and nuclear law has raised problems which it was attempted to solve by specific standards. As regards the prevention of nuclear hazards, these standards are based on the recommendations of competent international organizations, while concerning compensation of nuclear damage, a Convention which has just come into force lays down that nuclear law has priority over maritime law. Despite the progress made, a study of the situation in this field shows that it can be further improved. (N.E.A.) [fr

    The proposed acquisition of nuclear-powered submarines by the Canadian Armed Forces raises a number of legitimate concerns, including that of their potential impact on the environment. The use of nuclear reactors as the propulsion units in these submarines merits special consideration. Radioactivity, as an environmental pollutant, has unique qualities and engenders particular fears among the general population. The effects of nuclear submarines on the environment fall into two distinct categories: those deriving from normal operations of the submarine (the chief concern of this paper), and those deriving from a reactor accident. An enormous body of data must exist to support the safe operation of nuclear submarines; however, little information on this aspect of the proposed submarine program has been made available to the Canadian public.

    Declaring nuclear preparedness 'immoral' helps to recreate the pacifism of 50 years ago. War itself is a dilemma, not the weapons with which it is waged. We must ask of the anti-war proposals: whom do they benefit. On the whole people concerned are ordinary citizens who are fearful of nuclear incineration. But marching with them is a spectrum of forces with other motivations and purposes. In a real life situation of international tension or crises, numbers of weapons in combination with their particular charateristics could mean the difference between peace and outbreak of war.

    1977-01-01

    Nuclear power plant structures are designed to withstand severe postulated seismic forces. Structures subjected to such forces may be found to ''overturn'', if the factor of safety is computed in the traditional way, treating these forces as static. This study considers the transient nature of the problem and draws distinction between rocking, tipping and overturning. Responses of typical nuclear power plant structures to earthquake motions are used to assess their overturning potential more realistically. Structures founded on both rock and soil are considered. It is demonstrated that the traditional factor of safety, when smaller than unity, indicates only minimal base rotations and not necessarily overturning. (auth.)

  2. Fernando Arrabal's "Ars Amandi": The Theme of Love in Selected Plays

    1977-09-01

    Full Text Available The evolution in Arrabal's treatment of the theme of love reflects both the development and enrichment of his dramatic techniques and the resolution of his own deep-seated psychological conflicts. Arrabal's theater utilizes his concept of dramatic ceremony to project his intense desire for personal, political and artistic liberation. Psychological and social forces combine to frustrate the fulfillment of love in his early theater ( Fando and Lis , 1956 but ultimately love functions to obviate both internal and external constraints. Sexual union, which receives its most rapturous affirmation in Arrabal's plays written during the late 1960's ( The Law of Barabbas , Ars Amandi , and Erotic Bestiality , reflects the reconciliation of dialectical forces present in man's psyche. Women come to serve as intermediaries between man and the world. And in the broadest sense, the dramatic structure of Arrabal's mature plays can be depicted as the movement from psychic fragmentation to psychic unity, effected by the force of love.

    Steel-concrete (SC) composite walls being considered and used as an alternative to conventional reinforced concrete (RC) walls in safety-related nuclear facilities due to their construction economy and structural efficiency. However, there is a lack of standardized codes for SC structures, and design guidelines and approaches are still being developed. This paper presents the development and verification of: (a) mechanics based model, and (b) detailed nonlinear finite element model for predicting the behavior and failure of SC wall panels subjected to combinations of in-plane forces. The models are verified using existing test results, and the verified models are used to explore the behavior of SC walls subjected to combinations of in-plane forces and moments. The results from these investigations are used to develop an interaction surface in principle force (S p1 –S p2 ) space that can be used to design or check the adequacy of SC wall panels. The interaction surface is easy to develop since it consists of straight line segments connecting anchor points defined by the SC wall section strengths in axial tension, in-plane shear, and compression. Both models and the interaction surface (for design) developed in this paper are recommended for future work. However, in order to use these approaches, the SC wall section should be detailed with adequate shear connector and tie bar strength and spacing to prevent non-ductile failure modes

    This paper describes a study conducted by the National Laboratory for Civil Engineering of Portugal (LNEC), in cooperation with the Defense University Center at the Spanish Naval Academy and "La Sapienza," University of Rome, to assess the health and safety conditions of the Noble Hall floor in the São Carlos National Theater (Lisbon, Portugal). In a multidisciplinary approach, extensive fieldwork was carried out. The survey included the location and characterization of beams in the various areas of the floor by using two ground penetrating radar (GPR) systems equipped with two different ground- or air-coupled antennas, local inspection openings to visually assess the geometry, timber species and conservation state of structural members, and an assessment of the conservation state of the timber beam ends using drilling equipment. All the tests performed and the results obtained are presented. The potential of using non-destructive tests for the inspection of timber cultural heritage structures, particularly GPR, is discussed, and some practical recommendations are made.

  7. Hadronic and nuclear interactions in QCD

    International Nuclear Information System (INIS)

    1982-01-01

    Despite the evidence that QCD - or something close to it - gives a correct description of the structure of hadrons and their interactions, it seems paradoxical that the theory has thus far had very little impact in nuclear physics. One reason for this is that the application of QCD to distances larger than 1 fm involves coherent, non-perturbative dynamics which is beyond present calculational techniques. For example, in QCD the nuclear force can evidently be ascribed to quark interchange and gluon exchange processes. These, however, are as complicated to analyze from a fundamental point of view as is the analogous covalent bond in molecular physics. Since a detailed description of quark-quark interactions and the structure of hadronic wavefunctions is not yet well-understood in QCD, it is evident that a quantitative first-principle description of the nuclear force will require a great deal of theoretical effort. Another reason for the limited impact of QCD in nuclear physics has been the conventional assumption that nuclear interactions can for the most part be analyzed in terms of an effective meson-nucleon field theory or potential model in isolation from the details of short distance quark and gluon structure of hadrons. These lectures, argue that this view is untenable: in fact, there is no correspondence principle which yields traditional nuclear physics as a rigorous large-distance or non-relativistic limit of QCD dynamics. On the other hand, the distinctions between standard nuclear physics dynamics and QCD at nuclear dimensions are extremely interesting and illuminating for both particle and nuclear physics

    The technology of telerobotic control through a universal and transparent Man-Machine Interface is a growing field of robotics research in today's industrial scenario because of its promising application in hazardous and unstructured environments. The joystick, a sophisticated information receiver-translator-transmitter device, serves as a Man-Machine Interface for telerobots. The present paper describes the development paradigms of a remote control system for a planar four degrees-of-freedom joystick following position feed-forward force/torque feedback strategy in a bi-lateral mode. This joystick based control technology is designed to actuate an industrial robot working in nuclear power plant. The remote control system has been illustrated with model, algorithm, electronic hardware and software routines along with experimental results in order to have effective telemanipulation

  10. Feeding the nuclear pipeline: Enabling a global nuclear future

    Full text: There is nothing more vital to the advancement of human civilization than the abundance of usable and affordable energy. It underpins national security, economic prosperity, and global stability. Nuclear energy, which exhibits a unique combination of environmental and sustainable attributes, appears strongly positioned to play a much larger and more pivotal role in the mix of future global energy supplies than it has played in the past. Unfortunately, after a fairly rapid growth period within the industrialized nations in the 1960 to 1980 time frame, a variety of factors led to a substantial reduction in commercial nuclear power plant construction (with the possible exception of several Pacific Rim countries). This, in turn, led to a serious erosion in the enrollment patterns of nuclear engineering programs - causing alarmingly low enrollment levels in many counties by the turn of the century. Numerous studies conducted over the past five years have soberly come to the consistent conclusion that the nuclear pipeline cannot keep up with the needs of the nuclear industry. In fact, when combining the aging work force with low matriculation rates in most nuclear engineering academic programs, a huge (and unacceptable) mismatch between needs and supply is strikingly evident. This is further exasperated by the lack of meaningful efforts to capture the knowledge of the 'first nuclear era' professionals in a form that can be effectively transferred to the upcoming generation. Methods must be found to better capture the enormous body of experience already accumulated and both document it and then mentor the new nuclear engineers that do enter the work force to enable them to build upon this experience, rather than having to re-create it. On the positive side, enrollment patterns in the majority of nuclear engineering programs still in existence within the United States are now generally on the rise, at least at the undergraduate level. Some programs have

    Full Text Available Objective: To understand the importance of theater as an occupational therapy resource for the prevention of substance abuse by teens enrolled in a community-based psychosocial project. Methods: A qualitative, descriptive study with a critical reflection approach held at a community center in the Community of Dendê, Fortaleza-Ceará, Data were collected from March to May 2009 in a group of ten (10 teenagers of both sexes, aged 12 to 18 years, who lived in socially vulnerable situations and participated in the GESTTO group (Group of Socio-theatrical Expressions in Occupational Therapy. A structured interview was used with a simple observation of groups of theatrical activities and a field book. The analysis of the empirical material was based on Orlandi’s discourse analysis. Results: It was found that theatrical activities used as an occupational therapy resource constitute a powerful tool for the prevention of substance abuse, promoting increased self-esteem, the restructuring of the model of social identity, and the discovery of potentialities and abilities by teenagers so that they can become peer educators for the prevention of substance abuse in the community. Conclusion: The theatrical activity provided teenagers with a clear understanding of the use and abuse of illicit drugs, making them more sensitive to prevention and self-identity, making a significant change in their lives. doi:10.5020/18061230.2013.p333

    Although the ventilation system is widely employed in the operating theater, a strictly sterile surgical environment still cannot be ensured because of laminar disturbance, which is mainly caused by the surgical lighting system. Abandoning traditional products, we propose an LED surgical lighting system, which can alleviate the laminar disturbance and provide an appropriate lighting condition for surgery. It contains a certain amount of LED lens units, which are embedded in the ceiling and arranged around the air supply smallpox. The LED lens unit integrated with an LED light source and a free-form lens is required to produce a uniform circular illumination with a large tolerance to the change of lighting distance. To achieve such a dedicated lens, two free-form refractive surfaces, which are converted into two ordinary differential equations by the design method presented in this paper, are used to deflect the rays. The results show that the LED surgical lighting system can provide an excellent illumination environment for surgery, and, apparently, the laminar disturbance also can be relieved.

    Full Text Available The Opera of the National Theater in Belgrade was founded in 1920, but it is well known that opera performances were held long before its official opening. Despite the fact that this is the sole opera house in Belgrade (and one of the only two in Serbia, as well as the fact that it did not face any strong audience fluctuation, it is unusual that no one ever tried to investigate and profile its audience. During the last decades we were witnessing the popularization of the opera via various medias, as well as development and extention of the music industry, which surely changed its social status. The aim of the investigation that is going to be presented is to discover if this social life of opera changed its audience and does it still consists of - according to stereotypes - elderly, high educated individuals of certain professions and high material standards, i.e. at which level the opera is present in the private and public sphere of their lives.

    Policies to control the spread of nuclear weapons have assumed that the rapid worldwide spread of nuclear power is essential to replace oil, is both economically desirable and inevitable, and that the international political order must remain inherently discriminatory and dominated by the nuclear arms race. These assumptions are challenged as contrary to economic fact and market behavior. The authors feel that the link between nuclear reactors and nuclear bombs is inextricable, making proliferation inevitable and nuclear power a dangerous and costly alternative to oil. Instead, they suggest that nuclear power will collapse in response to market forces because only a few centrally-planned economies can override economic pressures. Acknowledgement of this collapse should be encouraged and the benefits of nuclear power accepted as illusory, according to the authors. 349 references, 2 figures

    The NEA Table on Nuclear Operator Liability Amounts and Financial Security Limits (NEA 'Liability Table'), which covers 71 countries, aims to provide one of the most comprehensive listings of nuclear liability amounts and financial security limits. The current and revised Paris and Brussels Supplementary Conventions ('Paris-Brussels regime'), the original and revised Vienna Conventions ('Vienna regime') and the Convention on Supplementary Compensation for Nuclear Damage, newly entered into force in April 2015, provide for the minimum amounts to be transposed in the national legislation of states parties to the conventions, and have served as guidelines for non-convention states. This article examine in more detail increases in the liability amounts provided for under these conventions, as well as examples of non-convention states (China, India and Korea)

    A component-scale thermal-hydraulics analysis module, the CUPID code has been being developed for a transient three-dimensional two-phase flow analysis of nuclear reactor components. The CUPID is based on a two-fluid, three-field model, which is solved by using an unstructured finite volume method. In the two-fluid momentum equation, the most important term to be modeled is the interfacial surface force. The simplest way to model this force is to formulate as the linear combination of various known interfacial forces such as the standard drag force, the virtual mass force, the Basset force, the lift force, the wall lift force, and the turbulent dispersion force. The standard drag force and the virtual mass force, which is essential for two-fluid computational models, are already considered in the CUPID code. In this paper, the wall lubrication force, the lift force, and the turbulent dispersion force including turbulence models, which play an important role on a radial distribution of the void in a two-phase flow, were implemented into the CUPID code, and the effect of these forces were verified qualitatively.
