    1994-05-01

    In this issue of Arms Control and Nonproliferation Technologies we present the initial findings of the recent Non-Proliferation Experiment (NPE), conducted by the Department of Energy at the Nevada Test Site. Through an introduction and pictorial walk-through, Marv Denny and Jay Zucca of Lawrence Livermore National Laboratory describe the overall experiment. This is followed by scientific and technical abstracts of the complex suite of experiments and analyses, which were presented at the Symposium on Non-Proliferation Experiment Results and Implications for Test Ban Treaties, April 19--21, 1994. Questions regarding the ongoing analysis and conclusions from the NPE should be directed to Leslie Casey in the Office of Research and Development within the Office of Nonproliferation and National Security of DOE. Her phone number is 202-586-2151.

  2. Comparison of chemical and nuclear explosions: Numerical simulations of the Non-Proliferation Experiment

    In this paper the authors discuss numerical simulations of the Non-Proliferation Experiment (NPE), which was an underground explosion conducted in September 1993 in the volcanic tuff of the Nevada Test Site. The NPE source consisted of 1.29 {times} 10{sup 6} kg of ANFO-emulsion blasting agent, with the approximate energy of 1.1 kt, emplaced 389 m beneath the surface of Rainier Mesa. The authors compare detailed numerical simulations of the NPE with data collected from that experiment, and with calculations of an equally energetic nuclear explosion in identical geology. Calculated waveforms, at ranges out to approximately 1 km, agree moderately well in the time domain with free-field data, and are in qualitative agreement with free-surface records. Comparison of computed waveforms for equally energetic chemical and nuclear sources reveals relatively minor differences beyond the immediate near-source region, with the chemical source having an {approximately}25% greater seismic moment but otherwise indistinguishable (close-in) seismic source properties. 41 refs., 67 figs., 7 tabs.

    To address a critical verification issue for the current Non-Proliferation Treaty (NPT) and for a possible future Comprehensive Test Ban Treaty (CTBT), the Department of Energy sought to measure certain differences between an underground nuclear test and a chemical test in the same geology, so that other explosions could be identified. This was done in a field experiment code-named the NonProliferation Experiment (NPE).This comprehensive experiment was designed to determine the signatures of chemical explosions for a broad range of phenomena for comparison with those of previous nuclear tests. If significant differences can be measured, then these measures can be used to discriminate between the two types of explosions. In addition, when these differences are understood, large chemical explosions can be used to seismically calibrate regions to discriminate earthquakes from explosions. Toward this end, on-site and off-site measurements of transient phenomena were made, and on-site measurements of residual effects are in progress.Perhaps the most striking result was that the source function for the chemical explosion was identical to that of a nuclear one of about twice the yield. These proceedings provide more detailed results of the experiment.

  4. Constructing a large-scale 3D Geologic Model for Analysis of the Non-Proliferation Experiment

    Wagoner, J; Myers, S

    2008-04-09

    We have constructed a regional 3D geologic model of the southern Great Basin, in support of a seismic wave propagation investigation of the 1993 Nonproliferation Experiment (NPE) at the Nevada Test Site (NTS). The model is centered on the NPE and spans longitude -119.5{sup o} to -112.6{sup o} and latitude 34.5{sup o} to 39.8{sup o}; the depth ranges from the topographic surface to 150 km below sea level. The model includes the southern half of Nevada, as well as parts of eastern California, western Utah, and a portion of northwestern Arizona. The upper crust is constrained by both geologic and geophysical studies, while the lower crust and upper mantle are constrained by geophysical studies. The mapped upper crustal geologic units are Quaternary basin fill, Tertiary deposits, pre-Tertiary deposits, intrusive rocks of all ages, and calderas. The lower crust and upper mantle are parameterized with 5 layers, including the Moho. Detailed geologic data, including surface maps, borehole data, and geophysical surveys, were used to define the geology at the NTS. Digital geologic outcrop data were available for both Nevada and Arizona, whereas geologic maps for California and Utah were scanned and hand-digitized. Published gravity data (2km spacing) were used to determine the thickness of the Cenozoic deposits and thus estimate the depth of the basins. The free surface is based on a 10m lateral resolution DEM at the NTS and a 90m lateral resolution DEM elsewhere. Variations in crustal thickness are based on receiver function analysis and a framework compilation of reflection/refraction studies. We used Earthvision (Dynamic Graphics, Inc.) to integrate the geologic and geophysical information into a model of x,y,z,p nodes, where p is a unique integer index value representing the geologic unit. For seismic studies, the geologic units are mapped to specific seismic velocities. The gross geophysical structure of the crust and upper mantle is taken from regional surface

  5. Bearing Condition Recognition and Degradation Assessment under Varying Running Conditions Using NPE and SOM

    Full Text Available Manifold learning methods have been widely used in machine condition monitoring and fault diagnosis. However, the results reported in these studies focus on the machine faults under stable loading and rotational speeds, which cannot interpret the practical machine running. Rotating machine is always running under variable speeds and loading, which makes the vibration signal more complicated. To address such concern, the NPE (neighborhood preserving embedding is applied for bearing fault classification. Compared with other algorithms (PCA, LPP, LDA, and ISOP, the NPE performs well in feature extraction. Since the traditional time domain signal denoising is time consuming and memory consuming, we denoise the signal features directly in feature space. Furthermore, NPE and SOM (self-organizing map are combined to assess the bearing degradation performance. Simulation and experiment results validate the effectiveness of the proposed method.

  8. IAEA safeguards and non-proliferation

    1995-02-01

    An overview is given of efforts to contain the nuclear weapons proliferation during half a century of man-controlled nuclear fission. An initial policy of denial did not work, a following period of cooperation needed a gradual strengthening of international assurances on the peaceful character of the flourishing use of nuclear techniques for power generation and of other applications. The focus of the nuclear weapon proliferation concern changed from the highly developed states to developing states. The Non-Proliferation Treaty laid the basis for a unique system of voluntarily accepted international inspections to verify the peaceful use of nuclear energy. The IAEA got the task to implement this `Full Scope Safeguards` on all nuclear material and all nuclear activities in the non-nuclear weapon states. Thanks to the structure of the IAEA, in which both proponent and states with a critical attitude take part in the decision making process on the IAEA execution of its tasks, a balanced, and widely acceptable system emerged. International developments necessitated additional improvements of the non-proliferation system. The increase of strength of sub-national groups triggered international cooperation on physical protection, about a quarter of a century ago. More recently, it appeared that NPT states with assumed nuclear weapon ambitions operated in the margins between the interpretation of IAEA safeguards and the spirit and purpose of NPT. Improvements of the IAEA safeguards and a stronger cooperation between states, including the constraints which exporting states have imposed on nuclear supplies, strengthen the safeguards system. The important reductions in the two largest nuclear weapon arsenals lead, together with the delay in the fast breeder implementation, to large stockpiles of nuclear weapon usable materials. Also in this areas new internationally credible assurances have to be obtained, that these materials will never return to nuclear weapon applications.

    The objective of this study is to analyze and foresee trends of international nuclear non-proliferation regimes focused on the nuclear non-proliferation policy of the Obama administration, and suggest national policy directions which promote utilization and development of nuclear energy in Korea. For the effective and efficient implementation of the national nuclear use and development program in current international nuclear environment, many efforts should be made: to actively and positively participate in the international nuclear non-proliferation regime; to strengthen nuclear diplomacy in a more systematic manner; and to strengthen the international nuclear cooperation

    Latin America`s incorporation into the international nuclear non-proliferation regime is well advanced. The 1967 Tlatelolco Treaty, which established a regional nuclear-weapon-free zone (NWFZ), is nearing completion. A signal event occurred January 18, when Argentina and Chile deposited instruments of ratification to the treaty, leaving Brazil and Cuba the only major countries in Latin America that are not yet contracting parties. And after more than two decades of concern about the nuclear programs and policies in Argentina and Brazil, there is room for great optimism that Brazil may now be moving quickly on important non-proliferation issues. Even Cuba, the {open_quotes}bad boy of the neighborhood{close_quotes} in the eyes of many, which held aloof from the Tlatelolco process for three decades, has stated its willingness to join the zone in the future.

    The purpose of this project was to compile a course material that covers how the nuclear safeguards system has emerged and how it works today. The produced compendium is directed to both university students and people concerned by safeguards from the industry. The primary aim of the first part of this paper is to describe the historical development of this global non-proliferation system and its central tasks. A second purpose is to discuss the advantages and disadvantages of its current design in order to answer the following question: Can we today say that we have a functioning global non-proliferation system? Does it require further strengthening, and, if so, how can this be achieved? In the second section we review the verification regime within nuclear safeguards, i. e. describe the methods and techniques that are available to reassure the world community that concluded treaties are adhered to

    1984-01-01

    When a topic has been under discussion for almost 40 years there is a danger that the literature will become excessively esoteric and that, as Philip Grummett suggests, '...a new scholasticism will arise' (p.79). Originating in a November l982 seminar co-sponsored by the British International Studies Association and the Foreign and Commonwealth Office, this volume is a refreshing, well conceived, and well written antidote to that trend. It is also well timed for the 1985 NPT Review Conference. The eight chapters of the volume are divided into three sections. Following an introduction by Anthony McGrew that touches on all the major themes of the volume, the first section deals with the existing non-proliferation system. In three chapters the historical, institutional and policy-making elements of the present system are outlined. There is a vignette on the Nuclear Suppliers Group in Wilmshurst's chapter one (pp. 28-33). Fischer's informative chapter on the IAEA is followed by Gummett's examination of policy options, including, for example, the linking of conventional weapons transfer to non-proliferation policies. The second section, also of three chapters, examines current issues: the state of the international nuclear industry, and the non-proliferation policies of the United States and Britain. Walker's chapter focuses chiefly on change in the industry-from monopoly to pluralism in suppliers, the effect of the economic recession, and the combined effect of these two factors on international politics. Devine's American non-proliferation chapter is a statement of the State Department view, whilst Keohane's chapter on Britain attempts to put the Trident procurement into a proliferation context. The British chapter is present because of ethnocentric considerations.

    Agreements to reduce nuclear arms and prevent proliferation of nuclear weapons are technical as well as political documents. They must be both technically sound and politically acceptable. This presentation illustrates technical aspects of arms control and non-proliferation agreements, with examples from SALT I, INF, the HEU Agreement, START, and the Iran nuclear negotiations, drawing on 44 years of personal experience in the negotiation of these agreements. The lecture is designed to convey an appreciation of the role that individuals with technical training can play in diplomatic efforts to reduce nuclear forces and prevent nuclear proliferation.

    Since the end of the Cold War, the importance of non-proliferation of weapons of mass destruction(WMD) has been enhanced constantly in the U.S. national security strategy and on the agenda of the U.S. foreign policy, and non-proliferation gradually has becomes one of its most important policy objectives. As the sole superpower, the U.S. non-proliferation policy has not only influenced and changed the international non-proliferation regime dramatically, but also greatly affected the non-proliferation effect of the international community. To prevent WMD proliferation, the United States has to abandon the practice of selective non-proliferation, group politics, prejudice on different ideologies and social systems, and maintenance of the U.S. hegemony. While pursuing its and allies interests, it must also attach great importance to other countries interests.

    Historic Facts and Philosophy: In August, 1947, I participated in a secret meeting concerning the validity and use of a hydrogen bomb. I vigorously supported a ``Super Manhattan Project" to build an ``H" bomb. My philosophy at the time was `bigger and better,' to ensure that no nation attacked the U.S. Our retaliation with ``H" bombs vs. ``A" bombs would be too overwhelming for any nation to risk attacking us should they obtain their own ``A" bombs. Thus, all nations would be forced to use diplomacy. I am older and wiser, and am now convinced that World Test Ban Treaties, non-proliferation of nuclear weapons, and space free of any military weapons is the best policy for all nations and humanity. With current nuclear testing at nearby Yucca Flats, Nevada, Vandenberg AF/Missile site, Cal Tech, etc., I therefore propose that our new APS California Division form a three-person committee to tabulate all pertinent data and submit it to a qualified expert for review and further action. Comments and suggestions are invited.

    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) prohibits all kinds of nuclear explosions. The International Monitoring System (IMS) is in place and at about 90% complete to verify compliance with the CTBT. The stations of the waveform technologies are capable to detect seismic, hydro-acoustic and infrasonic signals for detection, localization, and characterization of explosions. For practicing Comprehensive Nuclear-Test-Ban Treaty (CTBT) verification procedures and interplay between the International Data Centre (IDC) and National Data Centres (NDC), prepardness exercises (NPE) are regularly performed with selected events of fictitious CTBT-violation. The German NDC's expertise for radionuclide analyses and operation of station RN33 is provided by the Federal Office for Radiation Protection (BfS) while Atmospheric Transport Modelling (ATM) for CTBT purposes is performed at the Federal Institute for Geosciences and Natural Resources (BGR) for the combination of the radionuclide findings with waveform evidence. The radionuclide part of the NPE 2015 scenario is tackled in a joint effort by BfS and BGR. First, the NPE 2015 spectra are analysed, fission products are identified, and respective activity concentrations are derived. Special focus is on isotopic ratios which allow for source characterization and event timing. For atmospheric backtracking the binary coincidence method is applied for both, SRS fields from IDC and WMO-RSMC, and for in-house backward simulations in higher resolution for the first affected samples. Results are compared with the WebGrape PSR and the spatio-temporal domain with high atmospheric release probability is determined. The ATM results together with the radionuclide fingerprint are used for identification of waveform candidate events. Comparative forward simulations of atmospheric dispersion for candidate events are performed. Finally the overall consistency of various source scenarios is assessed and a fictitious government briefing on

    We report on the investigation of dielectron production in tagged quasi-free neutron-proton collisions by using a deuteron beam of kinetic energy 1.25GeV/u impinging on a liquid hydrogen target. Our measurements with HADES confirm a significant excess of e+e- pairs above the π0 mass in the exclusive channel dp → npe+e-(p_{spect}) as compared to the exclusive channel ppe+e- measured in proton-proton collisions at the same energy. That excess points to different bremsstrahlung production mechanisms. Two models were evaluated for the role of the charged pion exchange between nucleons and double- Δ excitation combined with intermediate ρ-meson production. Differential cross sections as a function of the e+e- invariant mass and of the angles of the virtual photon, proton and electrons provide valuable constraints and encourage further investigations on both experimental and theoretical sides.

    The paper is organized in three parts. The first one analyses the Treaty on the Non-proliferation of Nuclear Weapons (NPT) mentioning the arrangements and registered agreements between the IAEA and Member States. Also, the most important international legal instruments concerned the peaceful uses of nuclear energy are considered. In the second part, other international, regional or national legal instruments are discussed, particularly the London Club Guidelines, Treaty of Tlatelolco, the EURATOM and the Commission of the European Communities (CEC) Treaties, besides the American law of 18 Mars, 1978 - Nuclear Non-proliferation Act (NNPA) about the exportation of materials and services or nuclear technology; An appreciation about the laws and treaties are presented in the third part. Special attention is given to reinforce the non-proliferation dispositives face the actions after Iraq`s event (1990): new installations and nuclear activities moratorium extension export controls extension established by the London Club Guidelines and full scope safeguards adoption to accomplish controls and protect of dual-use nuclear-related technologies. 3 refs.

  8. Preparation for the Nuclear Non-Proliferation Treaty Extension Conference in 1995. Workshop summary

    Energy Technology Data Exchange (ETDEWEB)

    Chrzanowski, P.L.

    1993-05-07

    About 30 specialists in non-proliferation participated in a workshop to explore ideas for US Government preparatory steps leading to the 1995 Nuclear Non-Proliferation Treaty (NPT) Extension Conference. To that end, workshop sessions were devoted to reviewing the lessons learned from previous Review Conferences, discussing the threats to the non-proliferation regime together with ways of preserving and strengthening it, and examining the management of international nuclear commerce. A fundamental premise shared by workshop participants was that extension of the NPT is immensely important to international security. The importance of stemming proliferation and, more specifically, extending the Treaty, is growing as a result of the significant changes in the world. If the conferees of the Extension Conference decide on no extension or extension for a short limited duration, some technically advanced states that have foregone development of nuclear weapons may begin to rethink their options. Also, other arms control measures, such as the Chemical Weapons Convention, could start to unravel. The US must provide strong international leadership to ensure that the Extension Conference is a success, resulting in Treaty extension, perhaps through successive terms, into the indefinite future. Workshop participants were struck by the urgent need for the US to take organizational steps so that it is highly effective in its advance preparations for the Extension Conference. Moreover, the Extension Conference provides both a challenge and an opportunity to mold a cohesive set of US policy actions to define the future role of nuclear weapons and combat their proliferation.

  9. Finland and nuclear non-proliferation: The evolution and cultivation of a norm

    Energy Technology Data Exchange (ETDEWEB)

    1998-03-01

    Finland``s entrance on the non-proliferation scene was in 1963 when President Kekkonen suggested a Nordic nuclear-weapons-free zone (NWFZ). This started a debate in and among the Nordic countries and it created a Finnish profile towards the Soviet Union. In most cases, the Soviets tried to bring Finland into a much closer relationship with the USSR. The mere prospect and debate on a Nordic NWFZ reduced the incentive for the Soviets to undermine Finnish neutrality or their desire to suggest consultations according to the Treaty of Friendship, Cooperation and Mutual Assistance on military assistance in the case of a threat to Soviet and/or Finnish security. During the negotiations on the Non-Proliferation Treaty, 1965-1968, Finland played a very active role as a bridge-builder, first between the superpowers and later between the developed and the developing world. This activity gave Finland a name in the UN, strengthened its neutrality and established good relations with the West as well. In 1978, Kekkonen brought up the Nordic NWFZ once more, this time under influence of certain strategic challenges to Finland and general East-West developments. In this Kekkonen had much backing by the public in Finland whereas other states reacted very reluctantly. Politics in Finland has to a large extent been marked by the relations with Russia and later the Soviet Union. However, nuclear non-proliferation was used to ease the weight of this imposing neighbour; a strategy that certainly must be regarded as successful. While achieving this, it was also possible to increase contacts with western states and remain accepted as a neutral state. For Finland, non-proliferation policy was initially a suitable issue to solve other problems than those related exclusively to proliferation. But it was also a policy with a high degree of persistence, pragmatism and willingness to work with concrete issues that maybe do not reach the international limelight in the short run but that work in

    At the request of the Swedish Government, the Swedish Nuclear Power Inspectorate has established a support and co-operation programme in the area of nuclear non-proliferation with Russia and several of the republics of the former Soviet Union. The Programme was initiated in 1991 and an overall goal is to accomplish national means and measures for control and protection of nuclear material and facilities, in order to minimise the risk of proliferation of nuclear weapons and illicit trafficking of nuclear material and equipment. The objective of the Swedish Support Programme is to help each, so called, recipient State to be able to, independently and without help from outside, take the full responsibility for operating a national non-proliferation system and thereby fulfil the requirements imposed through the international legal instruments. This would include both the development and implementation of a modern nuclear legislation system, and the establishment of the components making up a national system for combating illicit trafficking. The support and co-operation projects are organised in five Project Groups (i.e. nuclear legislation, nuclear material control, physical protection, export/import control, and combating of illicit trafficking), which together cover the entire non-proliferation area. Up till June 2000, support and co-operation projects, completed and on-going, have been carried out in ten States, namely Armenia, Azerbaijan, Belarus, Georgia, Kazakstan, Latvia, Lithuania, Moldova, Russia and Ukraine. Furthermore, programmes have been initiated during the first part of 2000 with Estonia, Uzbekistan, Kyrgyzstan and Tajikistan. In addition, assistance has been given to Poland on a specific nuclear material accountancy topic. All projects are done on request by and in co-operation with these States. The total number of projects initiated during the period 1991 to June 2000 is 109, thereof 77 have been completed and 32 are currently on-going. It is the

    Swedish research on nuclear weapons started at a modest scale in 1945 but was soon expanded. By the early 1950s the research programme started to face some of the problems that were going to accompany it for the rest of its life: different priorities and cost-estimates were made by the sectors that wanted to develop nuclear energy and those working on the bomb. Moreover, an introduction of nuclear weapons would lead to a major redistribution of resources to the disadvantage of the navy and army. The public and political debates intensified during the 1950s and culminated in 1960. At first, pro-nuclear voices had been strongest but were soon challenged by interest groups, unions and peace movements. 1960, a committee within the government had established a compromise: Nuclear weapons research for production of weapons would be terminated, while research on the consequences of nuclear weapons would continue. It was a cosmetic decision that could cover for a continued research on weapons design. Nevertheless, there are some general qualities from the debates that indicate why the outcome was that Sweden signed the NPT in 1968. First, the number of interested persons, groups movements and party politicians engaged in the issue increased every time the issue came up. Secondly, the segments of society that supported the nuclear option remained roughly the same. No strong movements rallied to the defence of this position. On the other hand, the anti-nuclear wing received more and more followers. Third, there was a marked tendency by virtually all actors (except the military) to include every sign of progress in international disarmament and non-proliferation efforts as arguments against Swedish proliferation. Since 1968, the non-proliferation choice has ben manifested through Sweden``s adherence to the NPT and this has been accompanied by a strong commitment to other non-proliferation initiatives. Refs.

    This study analyzed the trends of the nonproliferation regimes in the following three aspects. First, this study analyzed the trends of the international nuclear non-proliferation regime, which includes the NPT, the IAEA safeguards system, the international nuclear export control regime and multilateral nuclear approach. Second, this study forecast the future trends of the nonproliferation systems with the reflection of current international situations. Third, this study also analyzed outstanding issues in nuclear control regimes and derived some factors to reflect national nuclear foreign policy.

    Extension of the Nuclear Non-Proliferation Treaty indefinitely was a historic decision. The Treaty is the most extensive international agreement on security policy to date; now its obligations have become a permanent part of international justice. Moreover, the NPT represents a political and moral obligation. Through the NPT, the international community has made a permanent commitment to restrict the proliferation of nuclear weapons. Increasing pressures will be applied to the few countries still outside the NPT, making it more likely that these countries will eventually change their views. The likelihood of regional bans on nuclear weapons in the Middle East and in Asia, too, will increase. The Treaty promotes the establishment of new nuclear-free zones. The nuclear-free zone in Latin America - the countries covered by the Tlatelolco Treaty - is already very close to its full implementation. Finland is firmly committed to the obligations of the Non-Proliferation Treaty. The NPT Conference of 1995 was among the first international meetings in which Finland participated, and took an active role, as a Member State of the European Union. (orig.).

    Latently infected resting CD4(+) T cells are a major barrier to HIV cure. Understanding how latency is established, maintained and reversed is critical to identifying novel strategies to eliminate latently infected cells. We demonstrate here that co-culture of resting CD4(+) T cells and syngeneic myeloid dendritic cells (mDC) can dramatically increase the frequency of HIV DNA integration and latent HIV infection in non-proliferating memory, but not naïve, CD4(+) T cells. Latency was eliminated when cell-to-cell contact was prevented in the mDC-T cell co-cultures and reduced when clustering was minimised in the mDC-T cell co-cultures. Supernatants from infected mDC-T cell co-cultures did not facilitate the establishment of latency, consistent with cell-cell contact and not a soluble factor being critical for mediating latent infection of resting CD4(+) T cells. Gene expression in non-proliferating CD4(+) T cells, enriched for latent infection, showed significant changes in the expression of genes involved in cellular activation and interferon regulated pathways, including the down-regulation of genes controlling both NF-κB and cell cycle. We conclude that mDC play a key role in the establishment of HIV latency in resting memory CD4(+) T cells, which is predominantly mediated through signalling during DC-T cell contact.

    2008-09-01

    The nuclear development programs of both Argentina and Brazil have, since the 1970s, been premised on the desire for self-sufficiency and assurance of nuclear fuel supply. While military rivalry and mutual distrust led to nuclear weapons related development programs in the 1970s and 1980s, both countries have since terminated these programs. Furthermore, the governments of both countries have pledged their commitment to exclusively non-explosive use of nuclear energy and have signed the Non Proliferation Treaty (NPT). Utilizing rights provided for under the NPT, both Argentina and Brazil have nuclear fuel production facilities, with the notable exception of enrichment plants, that provide much of the current indigenous fuel requirements for their nuclear power plants. However, both countries are actively developing enrichment capability to fill this gap. The purpose of this report is to assess the economic basis and non-proliferation policy considerations for indigenous enrichment capability within the context of their desired self-sufficiency and to evaluate possible United States Government policy options.

    Non-proliferation and nuclear safeguards are intimately connected with the peaceful development and use of nuclear power. The contractual obligation to forgo any misuse aimed at the construction of atom boms has been, and is, an important basis of all activities in the nuclear field. For the Federal Republic of Germany and the other participating states, subdivided into nuclear weapon states and non-nuclear-weapon states, the 1954 Brussels Treaty, which contains a fundamental clause waiving the production of nuclear weapons, the establishment of the European Atomic Energy Community, EURATOM, within the framework of the 1957 Treaties of Rome, and the Treaty on the Non-proliferation of Nuclear Weapons (Non-proliferation Treaty) within the framework of IAEA are the underlying basic legal instruments. These treaties, and the extended agreements based on them, operated on the basis of the 'old' system of surveillance of fissile material (nuclear safeguards). Both the inspection effort to be coped with by IAEA, which has kept rising steadily since the eighties and for which no additional budget funds were made available, and the violation by Iraq of the treaty as corroborated by a UN inspection team discovering a program for the production of weapons of mass destruction, boosted efforts in the early nineties to revise the existing system of treaties and controls. The International Atomic Energy Agency, among other measures, decided to improve nuclear safeguards by introducing immediate measures and optimization programs and upgrading inspection possibilities by a new model agreement. The model protocol, INFCIRC/153, adopted by the Board of Governors in September 1997 among other things serves to supplement the existing system of verification of the correctness of information received by another system verifying the completeness of such information. It incorporates an extended duty to supply information and extended rights of access. This includes activities not

    The Nuclear Control Institute welcomes this DOE-sponsored technical workshop on stabilization and immobilization of weapons plutonium (W Pu) because of the significant contribution it can make toward the ultimate non-proliferation objective of eliminating weapons-usable nuclear material, plutonium and highly enriched uranium (HEU), from world commerce. The risk of theft or diversion of these materials warrants concern, as only a few kilograms in the hands of terrorists or threshold states would give them the capability to build nuclear weapons. Military plutonium disposition questions cannot be addressed in isolation from civilian plutonium issues. The National Academy of Sciences has urged that {open_quotes}further steps should be taken to reduce the proliferation risks posed by all of the world`s plutonium stocks, military and civilian, separated and unseparated...{close_quotes}. This report discusses vitrification and a mixed oxide fuels option, and the effects of disposition choices on civilian plutonium fuel cycles.

    The Department of Energy is analyzing long-term storage and disposition alternatives for surplus weapons-usable fissile materials. A number of different disposition alternatives are being considered. These include facilities for storage, conversion and stabilization of fissile materials, immobilization in glass or ceramic material, fabrication of fissile material into mixed oxide (MOX) fuel for reactors, use of reactor based technologies to convert material into spent fuel, and disposal of fissile material using geologic alternatives. This paper will focus on how the objectives of reducing security and proliferation risks are being considered, and the possible facility impacts. Some of the areas discussed in this paper include: (1) domestic and international safeguards requirements, (2) non-proliferation criteria and measures, (3) the threats, and (4) potential proliferation, safeguards, and security issues and impacts on the facilities. Issues applicable to all of the possible disposition alternatives will be discussed in this paper. However, particular attention is given to the plutonium immobilization alternatives.

    The nuclear weapons non-proliferation treaty (NPT), signed on July 1, 1968 and enforced on March 5, 1970, has been progressively considered as the headstone of the international non-proliferation and disarmament regime. The sixth NPT examination conference took place at New York (USA) in the year 2000, 5 years after the previous conference but also after the first nuclear weapon tests of India and Pakistan. This article recalls up the main non-proliferation events that took place between the 1995 and 2000 conferences and presents the progresses and results of the New York conference. Finally, it wonders about the ambiguities in the conclusions of this last conference. (J.S.)

    The ILG has worked as an independent group under the Swedish Support Programme on Nuclear Non-Proliferation in Central and Eastern Europe and Central Asia. The ILG's mission is concluded with this report. When developing the seven Law Concepts on national nuclear legislation that are presented in this report, the ILG has applied certain basic principles, which are firmly established in modern Western legislation. A summary of these principles is made here. They are essential cornerstones in laws and regulations that apply both to the nuclear industry and to other high technology areas, characterised by advanced safety and security requirements. Of essential importance is that the Operator alone is responsible for the fulfilment of requirements stipulated in laws and authority directives. The technical complexity of the nuclear industry and the far-reaching requirements on safety and security necessitate a qualified and complete national system of legislation and regulations. As all legislation in general, the nuclear legislation should be clear, easy to understand and give little room for misunderstandings and loopholes. It should also present the legally established requirements on safety and security in a form that facilitates the application and implementation by both state authorities, facility operators and individuals. The investigations of the causes of the Three Mile Island and Chernobyl accidents brought into focus the impact on nuclear safety from human failure. As a consequence, increased emphasis has since then been put on the development of an overall high safety culture in the nuclear field. It is recognised that a good safety culture also promotes the non-proliferation systems and safeguards measures and helps to reduce the risk of illicit trafficking. In a high safety culture environment, each individual facility employee has to be motivated and encouraged to carry out the assigned duties and responsibilities in accordance with rules and

    The Nuclear Non-Proliferation Treaty (NPT) is the most important international security arrangement that we have that is protecting the world community and this has been true for many years. But it did not happen by accident, it is a strategic bargain in which 184 states gave up the right forever to acquire the most powerful weapon ever created in exchange for a commitment from the five states allowed to keep nuclear weapons under the NPT (U.S., U.K., Russia, France and China), to share peaceful nuclear technology and to engage in disarmament negotiations aimed at the ultimate elimination of their nuclear stockpiles. The most important part of this is the comprehensive nuclear test ban (CTBT); the thinking by the 184 NPT non-nuclear weapon states was and is that they understand that the elimination of nuclear weapon stockpiles is a long way off, but at least the NPT nuclear weapon states could stop testing the weapons. The CTBT has been ratified by 161 states but by its terms it can only come into force if 44 nuclear potential states ratify; 36 have of the 44 have ratified it, the remaining eight include the United States and seven others, most of whom are in effect waiting for the United States. No state has tested a nuclear weapon-except for complete outlier North Korea-in 15 years. There appears to be no chance that the U.S. Senate will approve the CTBT for ratification in the foreseeable future, but the NPT may not survive without it. Perhaps it is time to consider an interim measure, for the UN Security Council to declare that any future nuclear weapon test any time, anywhere is a "threat to peace and security", in effect a violation of international law, which in today's world it clearly would be.

    Full Text Available Abstract Background Our objectives are to analyse and to compare the stress distribution and displacement of the craniofacial structures, following the application of forces from quad-helix and Nickel Titanium Palatal Expander-2 (NPE2 using finite element analysis. Methods Three-dimensional finite element models of young dried human skull, quad-helix appliance and NPE2 were constructed, and the initial activation of the expanders was stimulated to carry out the analysis and to evaluate the Von Misses stresses and displacement. Results Both the models demonstrated the highest stresses at the mid-palatal suture, with maximum posterior dislocation. The second highest stress was recorded at the fronto-zygomatic suture. The pattern of stress distribution was almost similar in both the groups, but NPE2 revealed lower magnitude stresses than quad-helix. The only exception being quad-helix model showed high stress levels around pterygo-maxillary suture whereas minimal stress around pterygo-maxillary suture was noticed after NPE2 activation. The cusp of the erupting canine and the erupting mesiobuccal cusp of the second molar showed outward, backward and downward displacement signifying increase in their eruption pattern following maxillary expansion. Conclusions Maxillary expansion using quad-helix and NPE2 can be used in posterior crossbite correction in cases where maximum skeletal changes are desirable at a younger age; it is furthermore effective in treating young patients with impacted or displaced teeth. Quad-helix and NPE2 produced acceptable forces for orthopaedic treatment even after being orthodontic appliances; their clinical application should be correctly planned as the effects of these appliances are largely age dependent.

    Efforts are made to analyze the project, the Advanced Spent Fuel Management Technology (ASFMT), which is currently carried out at Korea Atomic Energy Research Institute, on the technical feasibility and validity as well as on the nuclear non-proliferation concerns. The project is a part of a program under the 'Long and Midterm Nuclear Development Program'. On the technical analysis, reviewed the papers presented at the national and international meetings on the subject by KAERI staffs, and also participated to various technical discussions on the 'Mock-up Test', currently in progress. On the non-proliferation concerns, the ASFMT project was reviewed and analyzed in reference to various programs currently in progress or in a formulation stages in US, such as the DOE TOPS and ATW. Further reviewed the past JASNEC process and programs for possible application of the ASFMT project for JASNEC project. Provided a few thoughts for effectively carrying out the ASFMT project, and a plan for the next phase is presented.

    The Swedish Radiation Safety Authority (SSM) is trusted with the task of implementing Sweden's bilateral cooperation with Russia, Ukraine, Georgia, Belarus and Armenia in the fields of reactor safety, nuclear waste management, nuclear non-proliferation as well as radiation protection and emergency preparedness. In these fields, SSM also participates in a number of projects financed by the European Union. This report gives an overview of the cooperation projects in 2009 as well as the framework in which they are performed. Summaries of each project are given in an Appendix. The project managers in the Section for Cooperation and Development in the Department of International Affairs are responsible for the cooperation projects and the implementation of the bilateral programmes. But the positive outcome of the projects is also dependent on a large number of experts at SSM who work with the regulatory functions in the nuclear and radiation protection fields in a Swedish context as well as on external consultants. Together, their experience is invaluable for the implementation of the projects. But the projects also give experience of relevance for the SSM staff.

    The U.S. Department of Energy (DOE) had a 35-year program for the sale and receipt (for reprocessing) of high-enriched research reactor fuel for foreign research reactors, executed pursuant to bilateral agreements with nuclear trading partners. In 1988, DOE abruptly let this program lapse, citing environmental obstacles. DOE promised to renew the program upon completion of an environmental review which was to take approximately six months. After three and a half years, an environmental assessment was finally produced.Over a year and half elapsed since publication of the assessment before DOE finally took action to renew the program. The paper sets forth the nuclear non-proliferation and related foreign policy considerations which support renewal of the program. It also summarized the contractual and other commitments made to foreign research reactors and foreign governments and aspects of U.S. environmental law as they apply to continuation of the program.

    2012-12-01

    Full Text Available Much has been written about perceived weaknesses of the NPT and the challenges it has been facing over the last decades. Analysing the most important provisions of the NPT, this article demonstrates how the treaty has managed to maintain its central role in the non-proliferation regime since its conclusion, and how it retains enough flexibility within its review mechanism and its managerial approach to supervision to keep this position for the decades to come. The theoretical framework of the article is formed by theory of arms control law, relevant features of which are: a large influence of politics and national interests of states on the rule of law; its flexible yet treaty-based nature; and the distinctive role of supervision in order to ensure compliance with primary rules. The article analyses key NPT provisions. Based on Article VIII, the NPT Review Conferences have both an important political and legal function. They are the NPT’s mechanism for review, implementation and supervision; in legal terms, they enable the evolution of the NPT based on subsequent agreement and practice. The NPT articles on non-proliferation and disarmament illustrate how the NPT has evolved to close off loopholes (Articles I and II and retains its flexibility whilst providing a global platform for negotiations on nuclear disarmament (Article VI. Article III evolved and must be understood to oblige NPT states to sign an Additional Protocol (AP with the IAEA. Article IV sets the parameters for the peaceful uses of nuclear energy, but leaves room for negotiation and conflict. The supervision of the NPT, illustrated by the case of Iran, is a complicated process involving international organisations such as the IAEA and the UNSC; while these may play important roles, however, the enforcement of the NPT is ultimately left to the NPT states themselves.

    Full Text Available The Non-Proliferation Treaty (NPT is an international treaty that should be implemented during both peace and wartime. However, the obligations included in the treaty are dependent upon states' attitudes regarding other issues. Non-use of nuclear weapons is directly related to negotiations done for the purpose of non-proliferation of nuclear weapons, non-production or accumulation by other means and disarmament. In our day, prevention of the proliferation of nuclear weapons has been one of the issues of international law.The present study is of crucial significance due to its endeavor to clarify the general principles of Humanitarian Law in a relationship to the threat of nuclear weapons' up to now, a special norm; significantly limiting or completely prohibiting the use of nuclear weapons, has not been accepted in international law. However, customary international humanitarian law regarding the use of nuclear weapons holds great value because of its purpose in eliminating nuclear weapons as a means of war through ascertaining their non-use and also appeasing the importance of nuclear ascendancy. In this respect, the NPT regime and its relationship with international humanitarian law will be discussed. Firstly, the NPT background, formation, main objectives and principles will be analyzed. In order to evaluate the relationship between the NPT and humanitarian law, the humanitarian obligations in general, humanitarian obligations in the context of the NPT and fulfillmen t of these obligations under the NPT should be studied. One of the main parts of the study is nuclear disarmament obligation included in the NPT. In this section, nuclear disarmament obligation in the context of the NPT and the legal framework of possible, general and comprehensive disarmament will be examined.

    This article discusses the role of the International Atomic Energy Agency (IAEA) in the prevention of the spread of nuclear weapons. The IAEA verifies States compliance with their non-proliferation commitments through the application of safeguards on their civilian nuclear programmes to ensure that they are being used solely for peaceful purposes. The IAEA safeguards have evolved in the course of five decades and have become an integral part of the international non-proliferation regime and the global security system. To continue to serve the international community, they need to continue to move with the times, especially in light of the renewed interest in nuclear energy. (Author)

    The Swedish Radiation Safety Authority (SSM) is trusted with the task of implementing Sweden's bilateral assistance to Russia, Ukraine, Georgia, Belarus and Armenia in the fields of reactor safety, nuclear waste management, nuclear non-proliferation as well as radiation protection and emergency preparedness. In these fields, SSM also participates in various projects financed by the European Union. The purpose of this project-oriented report is to provide the Swedish Government and other funding agencies as well as other interested audiences in Sweden and abroad with an encompassing understanding of our work and in particular the work performed during 2008. the activities are divided into four subfields: Nuclear waste management; Reactor safety; Radiation safety and emergency preparedness; and, Nuclear non-proliferation. SSM implements projects in the field of spent nuclear fuel and radioactive waste management in Russia. The problems in this field also exist in other countries, yet the concentration of nuclear and radioactive materials are nowhere higher than in north-west Russia. And given the fact that most of these materials stem from the Cold War era and remain stored under conditions that vary from 'possibly acceptable' to 'wildly appalling' it is obvious that Sweden's first priority in the field of managing nuclear spent fuel and radioactive waste lies in this part of Russia. The prioritisation and selection of projects in reactor safety are established following thorough discussions with the partners in Russia and Ukraine. For specific guidance on safety and recommended safety improvements at RBMK and VVER reactors, SSM relies on analyses and handbooks established by the IAEA in the 1990s. In 2008, there were 16 projects in reactor safety. SSM implements a large number of projects in the field of radiation protection and emergency preparedness. The activities are at a first glance at some distance from the activities covered and

    The regulatory control of nuclear materials (i.e. nuclear safeguards) is a prerequisite for the peaceful use of nuclear energy in Finland. Safeguards are required for Finland to comply with international agreements on nuclear non-proliferation - mainly the Non-Proliferation Treaty (NPT). This regulatory control is exercised by the Nuclear Materials Section of the Finnish Radiation and Nuclear Safety Authority (STUK). The results of STUK's nuclear safeguards inspection activities in 2011 continued to demonstrate that the Finnish licence holders take good care of their nuclear materials. There were no indications of undeclared nuclear materials or activities and the inspected materials and activities were in accordance with the licence holders' declarations.

    Although Nuclear Non-Proliferation Treaty is a product of power politics, it objectively plays an active role in the prevention of nuclear proliferation. As the foundation stone of nuclear non-proliferation regime, the treaty has experienced a lot of severe tests and nowadays is facing many challenges, which will have a bright future. In order to achieve the goal of Nuclear Non-Proliferation Treaty, nuclear disarmament and the right of non-nuclear states to peacefully use nuclear energy should be paid more attention in the future. Only in this way can the glorious desire of nuclear-free world be realized.%《不扩散核武器条约》虽然是强权政治的产物,但它在客观上为防止核扩散起着积极作用,是核不扩散体制的基石。该条约经历了许多严峻的考验,当今也面临不少的挑战,不扩散核武器条约的未来还是美好的。为了实现不扩散核武器条约的目标,今后更应关注核裁军和无核国家和平利用核能的权利。只有这样,无核世界的美好愿望才能实现。

    This report first gives an overview of nuclear disarmament and non proliferation twenty years after the end of Cold War: evolution and status of Russia's and United States' nuclear weapon arsenals, France's and United Kingdom's trend to reduce their nuclear armament, reinforcement of China's nuclear armament, effects and limitations of the Non Proliferation Treaty (NPT). It notices that the new international context gave birth to some expectations and may lead to a lower nuclear pressure, notably with the influence of START negotiations between Russia and the United States, provided that the Comprehensive Nuclear Test Ban Treaty is ratified by more countries, and that negotiations promote a Fissile Material Cut-off Treaty. The report also outlines the importance of the promotion of better controlled peaceful uses of nuclear energy. It discusses the relationship between maintaining the world nuclear order and the reduction of international and regional tensions, and the importance of struggle against all forms of proliferation. It analyses the French nuclear posture in terms of security requirements, and in front of the zero nuclear option, in a context of ballistic missile proliferation, and in relationship with the issue of tactical nuclear weapons in Europe

    The issue of nuclear weapons continues to appear as a focal point of International Relations. The efforts and concrete actions on disarmament, non-proliferation, and nuclear arms control are still issues that generate recurring tensions between States. However, in Brazil, there is little analysis of an academic nature about these issues and, with respect to current and prospective position of the Brazilian State in the Nuclear Weapons Non- Proliferation Regime, studies and analysis are even more scarce, or incipient. The present dissertation has as its object of study to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Regime arisen from NPT, and the Brazilian State insertion process in this Regime. Therefore our research work is structured in three areas: the first one is about the role of nuclear weapons in States security perception, the second is about NPT and its Regime, the third runs over the insertion of the Brazilian state in this regime. So, in summary, the research performed included the reasons that make a State to develop nuclear weapons, the NPT genesis and evolution of the perception of the meaning of that Treaty by the States, and the process and the degree of insertion of Brazil in the Nuclear Weapons Non- Proliferation Regime. The inquiry sought to place this object of study in the broader debate on Foreign Relations, based on the approaches of the discipline devoted to the question of managing the security of States, id est, the two approaches that constitute the mainstream of the discipline: the perspective theoretical liberal (and neoliberal variants) and realistic thinking (and neo-realist). Thus, we have used different theoretical lenses, which we think necessary for understanding the specific parts and causal connections between these parts of a complex issue. (author)

    The regimes of accountability, the organizations of global governance and institutional arrangements of global governance of nuclear non-proliferation and of Mutual Vigilance Brazilian-Argentine of Nuclear Safeguards are the subject of research. The starting point is the importance of the institutional model of global governance for the effective control of non-proliferation of nuclear weapons. In this context, the research investigates how to structure the current arrangements of the international nuclear non-proliferation and what is the performance of model Mutual Vigilance Brazilian-Argentine of Nuclear Safeguards in relation to accountability regimes of global governance. For that, was searched the current literature of three theoretical dimensions: accountability, global governance and global governance organizations. In relation to the research method was used the case study and the treatment technique of data the analysis of content. The results allowed: to establish an evaluation model based on accountability mechanisms; to assess how behaves the model Mutual Vigilance Brazilian-Argentine Nuclear Safeguards front of the proposed accountability regime; and to measure the degree to which regional arrangements that work with systems of global governance can strengthen these international systems.

    We discuss the feasibility of using the detection of electron antineutrinos produced in fission to monitor the time dependence of the Plutonium content of nuclear power reactors and large (> 1 MWatt) research reactors. If practical such a scheme would allow world-wide, automated monitoring of reactors and, thereby, the detection of proliferation attempts. Although this idea shows some promise, we find that a practical scheme is difficult to envision. We also consider using fission antineutrino spectra to determine and attribute the fuel in an unexploded nuclear device. We find it would not be possible to determine the isotopic content of such a device in this manner. Finally, we examine the possibility of antineutrino detection of an unannounced low-yield (~ 1kton) nuclear explosion. We argue this can be ruled out completely.

    The purpose of this paper is to discuss the value of 'security guarantees', that is, positive security assurances that include a formal or informal defense commitment, in preventing nuclear proliferation. It demonstrates that such guarantees have proven to be a very effective instrument in preventing States from going nuclear. It would thus seem logical to reinforce or extend them. However, this path is fraught with obstacles and dilemmas

  3. Fusion energy and nuclear non-proliferation

    Neutrons from DT fusion can be used to produce {sup 239}Pu or {sup 233}U. However since no fertile nor fissile material need be present in a pure fusion power plant, it would be relatively easy to detect significant covert transmutation in a declared facility. Clandestine fusion-based transmutation does not appear credible. Furthermore, no fissile materials are immediately available in a fusion breakout scenario. DT fusion systems produce and burn 400g of tritium per day, a small fraction of which, if diverted, could be used to enhance the efficiency, reliability and/or safety of a nuclear weapon. Very accurate T accountancy needs to be developed for fusion energy systems. Finally, the spread of inertial fusion energy R and D may result in dissemination of knowledge relevant to the design of nuclear weapons. International agreements to restrain information transfer are required. In summary, fusion is much safer from a proliferation standpoint than fission, but still requires verification and control.

    Japan and the United States signed in 1968 a new atomic energy agreement through which US light-water nuclear reactors, including those of the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company, were to be introduced into Japan. This paper studies the history of negotiations for the 1968 agreement using documents declassified in the 1990s in the US and Japan. After the success of the Chinese nuclear test in October 1964, the United States became seriously concerned about nuclear armament of other countries in Asia including Japan. Expecting that Japan would not have its own nuclear weapons, the US offered to help the country to demonstrate its superiority in some fields of science including peaceful nuclear energy to counter the psychological effect of the Chinese nuclear armament. Driven by his own political agenda, the newly appointed Prime Minister Eisaku Sato responded to the US expectation favorably. When he met in January 1965 with President Johnson, Sato made it clear that Japan would not pursue nuclear weapons. Although the US continued its support after this visit, it nevertheless gave priority to the control of nuclear technology in Japan through the bilateral peaceful nuclear agreement. This paper argues that the 1968 agreement implicitly meant a strategic measure to prevent Japan from going nuclear and also a tactic to persuade Japan to join the Nuclear Non -Proliferation Treaty.

    The direct measuring method is considered to get nuclear reactor antineutrino spectrum. We suppose to isolate partial spectra of the fissile isotopes by using the method of antineutrino spectrum extraction from the inverse beta decay positron spectrum applied at Rovno experiment. This admits to increase the accuracy of partial antineutrino spectra forming the total nuclear reactor spectrum. It is important for the analysis of the reactor core fuel composition and could be applied for non-proliferation purposes.

    The purpose of this paper is to report on the results of a project investigating support concepts for the information treatment needs of the International Atomic Energy Agency (IAEA, also referred to as the Agency) and its attempts to strengthen international safeguards. The aim of the research was to define user/computer interface concepts and intelligent support features that will enhance the analyst`s access to voluminous and diverse information, the ability to recognize and evaluate uncertain data, and the capability to make decisions and recommendations. The objective was to explore techniques for enhancing safeguards analysis through application of (1) more effective user-computer interface designs and (2) advanced concepts involving human/system collaboration. The approach was to identify opportunities for human/system collaboration that would capitalize on human strengths and still accommodate human limitations. This paper documents the findings and describes a concept prototype, Proliferation Analysis Support System (PASS), developed for demonstration purposes. The research complements current and future efforts to enhance the information systems used by the IAEA, but has application elsewhere, as well.

  9. The current perspectives of nuclear energy and non-proliferation

    Energy Technology Data Exchange (ETDEWEB)

    Gilinsky, Victor

    2012-07-01

    The main reason given nowadays for supporting nuclear plant construction around the world is that the plants do not produce CO{sub 2}. The negative aspects are costs so high as to require subsidies, the possible connection with proliferation, and since the Fukushima accident, a renewed concern about nuclear safety. To make a dent on global climate, we would need many power reactors, perhaps a thousand worldwide, perhaps more. Such a scale-up is not likely in view of nuclear power's high cost. Fukushima demonstrated that LWRs are capable of large accidental releases of radioactivity, roughly comparable to that at Chernobyl. While effective evacuation can protect people, the evacuates may never be able to return. The half- life of cesium 137, the main contaminant, is about 30 years, and it may take several half-lives to make an area acceptable for rehabilitation. In Fukushima about 100,000 persons were evacuated from an area of about 1000 square kilometer. When it comes to proliferation, there are strong arguments over whether we can have nuclear power without nuclear weapons. The 1946 US Acheson-Lilienthal Report argued that gaining nuclear energy's benefits without proliferation required strict international control. Inspection alone couldn't afford any reasonable security against the diversion of such materials to the purposes of war. The authors view is that the connection between technologies for nuclear power and nuclear weapons is still so close that you can't get the benefits of power without increasing the risks of weapons spread. Up to now we have allowed our interest in nuclear power to trump our bomb worries. It is time to rethink the proliferation risk of a large increase in nuclear power capacity.

    2005-07-01

    In this thorough study of the Nuclear Nonproliferation Treaty (NPT), the author looks at the origins of the NPT, its original bargains, and the current 'global crisis of compliance'. Then he looks to the 2005 NPT Review Conference for approaches 'to preserve the integrity and the credibility of the Treaty'. He suggests a new set of bargains centered around two issues: increase rewards for members in good standing of their obligations, but promote sanctions for those cheating; and recognize that nuclear disarmament is a distant goal, but satisfy the legitimate worries of NNWS (Non-Nuclear Weapon States)

    State space modeling, which includes techniques such as the Kalman filter, has been used to analyze many non-stationary time series. The ability of these dynamic models to adapt and track changes in the underlying process makes them attractive for application to the real-time analysis of three-component seismic waveforms. The authors are investigating the application of state space models formulated as Bayesian time series models to phase detection, polarization, and spectrogram estimation of seismograms. This approach removes the need to specify data windows in the time series for time averaging estimation (e.g., spectrum estimation). They are using this model to isolate particular seismic phases based on polarization parameters that are determined at a spectrum of frequencies. They plan to use polarization parameters, frequency spectra, and magnitudes to discriminate between different types of seismic sources. They present the application of this technique to artificial time series and to several real seismic events including the Non-Proliferation Experiment (NPE) two nuclear tests and three earthquakes from the Nevada Test site, as recorded on several regional broadband seismic stations. A preliminary result of this analysis indicates that earthquakes and explosions can potentially be discriminated on the bass of the polarization characteristics of scattered seismic phases. However, the chemical (NPE) and nuclear explosions appear to have very similar polarization characteristics.

    Full Text Available A fim de se entender como podemos explicar o comportamento das potências emergentes diante das instituições internacionais, este artigo analisa o caso de Brasil, Índia e do Tratado de Não Proliferação com maior profundidade e mostrar que nem os realistas nem os institucionalistas liberais podem explicar plenamente o comportamento de ambos os países. Argumenta-se, no artigo, que status e identidade, ambos amplamente negligenciados pelo realismo e pelo liberalismo, desempenham um papel-chave. Tanto o Brasil quanto a Índia compartilham uma convicção fundamental de que são "grandes potências" (ou estão no caminho de se tornarem uma, e sua decisão de integrar uma instituição particular depende da habilidade dessa instituição em conferir um status às potências emergentes que seja compatível com a identidade das potências emergentes. Como mostra o exemplo do TNP, status e identidade superam outros determinantes mais comumente aceitos para o comportamento dos Estados, como as preocupações com segurança.In order to understand how we can explain rising powers' behavior towards international institutions, this article analyzes the case of Brazil, India and the Non-Proliferation Treaty (NPT in more depth and shows that neither realists nor liberal institutionalists can fully explain both countries' behavior. In the article it is argued that status and identity, both largely overlooked by realism and liberalism, play a key role. Both Brazil and India share a fundamental conviction that they are 'great powers' (or on their way to becoming one, and their decision to integrate into a particular institution depends on this institutions' ability to confer status on the emerging powers that is compatible with the rising powers' identity. As the example of the NPT shows, status and identity override other, more commonly accepted determinants for states' behavior such as security concerns.

    Understanding the acoustic and infrasound source generation mechanisms from underground explosions is of great importance for usage of this unique data type in non-proliferation activities. One of the purposes of the Source Physics Experiments (SPE), a series of underground explosive shots at the Nevada National Security Site (NNSS), is to gain an improved understanding of the generation and propagation of physical signals, such as seismic and infrasound, from the near to far field. Two of the SPE shots (SPE-1 and SPE-4') were designed to be small "Green's Function" sources with minimal spall or permanent surface deformation. We analyze infrasound data collected from these two shots at distances from ~300 m to ~1 km and frequencies up to 20 Hz. Using weather models based upon actual observations at the times of these sources, including 3-D variations in topography, temperatures, pressures, and winds, we synthesized full waveforms using Sandia's moving media acoustic propagation simulation suite. Several source mechanisms were simulated and compared and contrasted with observed waveforms using full waveform source inversion. We will discuss results of these source inversions including the relative roll of spall from these small explosions. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

    Heavy quarks are suitable probes to study the properties of Quark-Gluon Plasma (QGP), a strongly interacting medium, which can be created in ultrarelativistic heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC). Non-photonic electrons (NPE) that originate from semileptonic decays of D and B mesons can serve as a good proxy for heavy flavor quarks. Nuclear modification factor RAA of NPE is measured in heavy-ion collisions, which is sensitive to the effect of QGP on heavy quarks. Measurements of NPE RAA in Au+Au collisions at √sNN = 200 GeV reveal that NPE production is strongly suppressed. In year 2012 STAR collected data from U+U collisions at √sNN = 193 GeV. In most central collisions higher energy density can be achieved in comparison to collisions of gold nuclei. In this proceedings the preliminary results on NPE in 0-5% most central U+U collisions at a transverse momentum range 1.2 < pT < 6 GeV/c are presented. The nuclear modification factor in U+U collisions is compared to that in Au+Au collisions and theoretical models.

    Neurogenic pulmonary edema (NPE) is a potentially catastrophic but treatable systemic event after subarachnoid hemorrhage (SAH). The development of NPE most frequently occurs immediately after SAH, and the severity is usually self-limiting. Despite extensive research efforts and a breadth of collective clinical experience, accurate diagnosis of NPE can be difficult, and effective hemodynamic treatment options are limited. Recently, a bedside transpulmonary thermodilution device has been introduced that traces physiological patterns consistent with current theories regarding the mechanism (hydrostatic or permeability PE) of NPE. This article provides an overview of the clinical usefulness of the advanced technique for use in the neurointensive care unit for the diagnosis and management of post-SAH NPE.

  18. Balancing Opposing Forces—A Nested Process Evaluation Study Protocol for a Stepped Wedge Designed Cluster Randomized Controlled Trial of an Experience Based Codesign Intervention

    Full Text Available Background: Process evaluations are essential to understand the contextual, relational, and organizational and system factors of complex interventions. The guidance for developing process evaluations for randomized controlled trials (RCTs has until recently however, been fairly limited. Method/Design: A nested process evaluation (NPE was designed and embedded across all stages of a stepped wedge cluster RCT called the CORE study. The aim of the CORE study is to test the effectiveness of an experience-based codesign methodology for improving psychosocial recovery outcomes for people living with severe mental illness (service users. Process evaluation data collection combines qualitative and quantitative methods with four aims: (1 to describe organizational characteristics, service models, policy contexts, and government reforms and examine the interaction of these with the intervention; (2 to understand how the codesign intervention works, the cluster variability in implementation, and if the intervention is or is not sustained in different settings; (3 to assist in the interpretation of the primary and secondary outcomes and determine if the causal assumptions underpinning the codesign interventions are accurate; and (4 to determine the impact of a purposefully designed engagement model on the broader study retention and knowledge transfer in the trial. Discussion: Process evaluations require prespecified study protocols but finding a balance between their iterative nature and the structure offered by protocol development is an important step forward. Taking this step will advance the role of qualitative research within trials research and enable more focused data collection to occur at strategic points within studies.

  1. Issues Involving The OSI Concept of Operation For Noble Gas Radionuclide Detection

    Energy Technology Data Exchange (ETDEWEB)

    Carrigan, C R; Sun, Y

    2011-01-21

    The development of a technically sound protocol for detecting the subsurface release of noble gas radionuclides is critical to the successful operation of an on site inspection (OSI) under the CTBT and has broad ramifications for all aspects of the OSI regime including the setting of specifications for both sampling and analysis equipment used during an OSI. With NA-24 support, we are investigating a variety of issues and concerns that have significant bearing on policy development and technical guidance regarding the detection of noble gases and the creation of a technically justifiable OSI concept of operation. The work at LLNL focuses on optimizing the ability to capture radioactive noble gases subject to the constraints of possible OSI scenarios. This focus results from recognizing the difficulty of detecting gas releases in geologic environments - a lesson we learned previously from the LLNL Non-Proliferation Experiment (NPE). Evaluation of a number of important noble gas detection issues, potentially affecting OSI policy, has awaited the US re-engagement with the OSI technical community. Thus, there have been numerous issues to address during the past 18 months. Most of our evaluations of a sampling or transport issue necessarily involve computer simulations. This is partly due to the lack of OSI-relevant field data, such as that provided by the NPE, and partly a result of the ability of LLNL computer-based models to test a range of geologic and atmospheric scenarios far beyond what could ever be studied in the field making this approach very highly cost effective. We review some highlights of the transport and sampling issues we have investigated during the past year. We complete the discussion of these issues with a description of a preliminary design for subsurface sampling that is intended to be a practical solution to most if not all the challenges addressed here.

    2008-03-01

    This report evaluates transportation issues for nuclear material in the proposed Global Nuclear Energy Partnership (GNEP) fuel cycle. Since many details of the GNEP program are yet to be determined, this document is intended only to identify general issues. The existing regulatory environment is determined to be largely prepared to incorporate the changes that the GNEP program will introduce. Nuclear material vulnerability and attractiveness are considered with respect to the various transport stages within the GNEP fuel cycle. Physical protection options are then outlined for the transportation of this nuclear material. It is determined that increased transportation security will be required for the GNEP fuel cycle, particularly for international transport. Finally, transportation considerations for several fuel cycle scenarios are discussed. These scenarios compare the current "once-through" fuel cycle with various aspects of the proposed GNEP fuel cycle. 3

    2012-10-01

    Full Text Available La Unión Europea has sido un actor relevante en las negociaciones con Irán desde el principio de la crisis nuclear iraní en el 2002. Sin embargo, la política de la Unión no se puede reducir únicamente al plano de la no proliferación nuclear. Principalmente, en los últimos 20 años ha estado promoviendo derechos humanos y democracia en el país. En otras palabras, la política Europea hacia Irán ha sido una política de múltiples planos cuyo objetivo ha sido la difusión de diferentes tipos de normas. Este artículo examina las consecuencias de la promoción simultánea por parte de la Unión Europea de normas en el campo de la buena gobernanza y en seguridad internacional, en particular en relación con las implicaciones de la clásica caracterización de la Unión Europea como un “poder normativo”. Se fija particularmente en los diferentes mecanismos e instrumentos de la Unión para la promoción de sus esfuerzos normativos. En contraste con los estudios existentes sobre la Europa del Poder Normativo, se concluye que en la práctica la Unión se enfrente a un dilema: puede bien intentar promover todas sus normas que representa de una manera coherente y pagar el precio en términos de efectividad de su política exterior; bien tratar de centrarse efectivamente en una única norma y ser objeto de acusaciones de doble estándar.

  6. Large-scale Gadolinium-doped Water Cerenkov Detector for Non-Proliferation

    2011-01-01

    Fission events from Special Nuclear Material (SNM), such as highly enriched uranium or plutonium, can produce simultaneous emission of multiple neutrons and high energy gamma-rays. The observation of time correlations between any of these particles is a significant indicator of the presence of fissionable material. Cosmogenic processes can also mimic these types of correlated signals. However, if the background is sufficiently low and fully characterized, significant changes in the correlated event rate in the presence of a target of interest constitutes a robust signature of the presence of SNM. Since fission emissions are isotropic, adequate sensitivity to these multiplicities requires a high efficiency detector with a large solid angle with respect to the target. Water Cerenkov detectors are a cost-effective choice when large solid angle coverage is required. In order to characterize the neutron detection performance of large-scale water Cerenkov detectors, we have designed and built a 3.5 kL water Cerenko...

    This journal article analyzes nuclear and security related events of the past 15 years to illustrate the changes in geopolitics and the shifting balance of power following the collapse of the Soviet Union. Reflection upon these events establishes the context for strengthening the nonproliferation regime. The author concludes that post Soviet communism hastened the movement towards a unipolar system with hegemonic power vested in the United States, and this geopolitical imbalance fostered insecurities and greater threats. Multilateral cooperation and commitment from the US would help this leader achieve its goal of security through increased global confidence in the international system.

    The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion.

  19. Mixture Experiments

    Energy Technology Data Exchange (ETDEWEB)

    Piepel, Gregory F.

    2007-12-01

    A mixture experiment involves combining two or more components in various proportions or amounts and then measuring one or more responses for the resulting end products. Other factors that affect the response(s), such as process variables and/or the total amount of the mixture, may also be studied in the experiment. A mixture experiment design specifies the combinations of mixture components and other experimental factors (if any) to be studied and the response variable(s) to be measured. Mixture experiment data analyses are then used to achieve the desired goals, which may include (i) understanding the effects of components and other factors on the response(s), (ii) identifying components and other factors with significant and nonsignificant effects on the response(s), (iii) developing models for predicting the response(s) as functions of the mixture components and any other factors, and (iv) developing end-products with desired values and uncertainties of the response(s). Given a mixture experiment problem, a practitioner must consider the possible approaches for designing the experiment and analyzing the data, and then select the approach best suited to the problem. Eight possible approaches include 1) component proportions, 2) mathematically independent variables, 3) slack variable, 4) mixture amount, 5) component amounts, 6) mixture process variable, 7) mixture of mixtures, and 8) multi-factor mixture. The article provides an overview of the mixture experiment designs, models, and data analyses for these approaches.

    My name is Nicoara Floarea and I am teacher at Secondary School Calatele and I teach students from preparatory class and the second grade . They are six-eight years old. In my activity, for introducing scientific concepts to my students, I use various and active methods or traditional methods including experiments. The experiment stimulates students' curiosity, their creativity, the understanding and knowledge taught accessibility. I propose you two such experiments: The life cycle of the plants (long-term experiment, with rigorous observation time):We use beans, wheat or other; They are grown in pots and on the cotton soaked with water,keeping under students' observation protecting them ( just soak them regularly) and we waiting the plants rise. For discussions and comments of plant embryo development we use the plants which rose on the cotton soaked with water plants at the end of the first week. Last school year we had in the pot climbing beans which in May made pods. They were not too great but our experiment was a success. The students could deduce that there will develop those big beans which after drying will be planted again. The influence of light on plants (average duration experiment with the necessary observation time): We use two pots in which plants are of the same type (two geraniums), one of them is situated so as to get direct sunlight and other plant we put in a closed box. Although we wet both plants after a week we see that the plant that benefited from sunlight has turned strain in direct sunlight, developing normally in return the plant out of the box I have yellowed leaves, photosynthesis does not She has occurred . Students will understand the vital role of the Sun in plants' life, both in the classroom and in nature. The experiment is a method of teaching students extremely pleasant, with a remarkable percentage of acquiring more knowledge.

  9. Aesthetic experience.

    Science.gov (United States)

    Sirois, François J

    2008-02-01

    An initial clinical question, 'Why does an analysand talk about his/her relationship with an aesthetic object?' opens an investigation into the nature of aesthetic experience. Three principal aspects of the psychoanalytic approach are presented: sublimation, a Freudian concept concerning the vicissitudes of the drives; reparation, a Kleinian concept linked to depressive anxiety; and transformation, a concept of object-relations theory about primitive ego-states. The article discusses the psychic function of aesthetic feelings in mastering anxiety as related to ego, id and superego. The transformation of the experience of passivity is a common link underlying these aspects. Such transformation relies on tolerating ambiguous and contrary feelings within the self, fostered by contact with an aesthetic object. This balance can, however, be upset: two excessive forms of aesthetic experience ensue, namely, fascination and bewitchment. The first belongs to the experience of awe; the second can lead to claustrophobic anxiety. The initial clinical question requires an elaboration of aesthetic transference, a variant of the narcissistic transference, whereby the analysand invites the analyst to share his/her internal state as a common unspoken object.

    The main objective of DIRAC experiment is the measurement of the lifetime tau of the exotic hadronic atom consisting of pi /sup +/ and pi /sup -/ mesons. The lifetime of this atom is determined by the decay mode pi /sup +/ pi /sup -/ to pi /sup 0/ pi /sup 0/ due to the strong interaction. Through the precise relationship between the lifetime and the S-wave pion-pion scattering length difference a/sub 0/-a/sub 2/ for isospin 0 and 2 (respectively), a measurement of tau with an accuracy of 10% will allow a determination of a/sub 0/-a/sub 2/at a 5% precision level. Pion-pion scattering lengths have been calculated in the framework of chiral perturbation theory with an accuracy below 5%. In this way DIRAC experiment will provide a crucial test of the chiral symmetry breaking scheme in QCD effective theories at low energies. (19 refs).

    ZrO2 crucible experiments were carried out in the laboratory to study the formation of low-melting-point inclusions in steel, during which aluminum deoxidization and a high-basicity calcium aluminate refining slag (CaO/SiO2: 6 to 8, Al2O3 40 to 45 pct) were used. Four experiments were done with different slag/steel reaction times (30, 60, 90, and 180 minutes). It was found that inclusions were mainly composed of CaO-Al2O3-ZrO2 with very limited SiO2, in spherical morphology and with sizes mainly less than 5 μm. They can be classified into two types according to the ZrO2 content. The first type contained much lower ZrO2, whereas a much higher level of ZrO2 was detected in the other type. An evolution of inclusions with the reaction time was observed and studied. The obtained results indicated that chemical compositions of inclusions were widely scattered in the CaO-Al2O3-ZrO2 phase diagram after 30 min reaction. However, the composition of inclusions became much more uniform and concentrated in low-melting-temperature regions at 60, 90, and 180 minutes, which would be favorable to prevent nozzle clogging and fatigue problems. Compared with the authors' previous results obtained in MgO crucible experiments, it was found that low-melting-temperature inclusions can be targeted in shorter time in ZrO2 crucible experiments, without any degradation of cleanliness.

    The measurement of the production of particles coming from hard scattering processes covers a fundamental role in the characterization of the system formed in heavy-ion collisions, allowing to probe the microscopic processes underlying the interaction of high energy partons with the medium. An impressive amount of measurements related to jet, quarkonia, open heavy flavor, and electroweak signal production in nucleus-nucleus as well as p(d)-nucleus collisions was delivered by experiments at RHIC and LHC in past years. In these proceedings, the main experimental results presented during the Hard Probes conference are summarized.

  15. Thomson Experiment

    CERN Multimedia

    This experiment, conducted by JJ Thomson in 1897, established the existence of the electron. Thomson won the Nobel physics prize for this work in 1906. A beam of electrons crosses the chamber emitting blue light. Adding an electric field (E) or a magnetic field (B) exerts a force on the moving electrons.Use switch E to turn on the electric field in the chamber. Then, by turning knob B, you can increase the current in the coils, generating a magnetic field. By balancing the electric and magnetic fields, Thomson was able to keep the electron beam level and deduce the ratio of the electron's charge to its mass.

For the development of a set of guidelines for the facilitation of citizens’ initiatives by local governments, we are experimenting with this method. It offers good opportunities for modeling interventions by testing their instrumental validity –the usefulness for the intended practical purposes. At the same time design experiments are also useful for evaluating the empirical validity of theoretical arguments and the further development of these arguments in the light of empirical evidence (by using e.g. the technique of pattern matching. We describe how we have applied this methodology in two cases and discuss our research approach. We encountered some unexpected difficulties, especially in the cooperation with professionals and citizens. These difficulties complicate the valid attribution of causal effects to the use of the new instrument. However, our preliminary conclusion is that design experiments are useful in our field of study

    This experiment, carried out by Ernest Rutherford in 1910, revolutionised understanding of the structure of matter, showing that almost all the mass of an atom is concentrated in a very small, positively charged nucleus. Alpha particles emitted at bombard a thin gold foil. A detector records the number of alpha particles crossing the foil per second. The number is displayed on the counter and updated every minute. Alpha particles are helium nuclei, they consist of 2 protons and 2 neutrons. Rotate the central knob to change the angle between the foil and the detector. The number of alpha particles detected depends on the angle. Most of the alpha particles travel straight through the foil because the gold atoms are mainly empty space. However some hit the atomic nucleus and are deflected.

By this online study one presents both the obstacles encountered and the recommendations for such a type of management that the present and future mangers must take into account. What motivated the respondent Romanian managers most to open their own business is the independence it offered them. They work in the field they have liked since they were young. The second reason was the perspective to have an additional income from the business development. The third argument in favour of opening a business is the possibility to assure the balance between personal life and career.

    This contract was awarded in response to a proposal in which a deployable plume and aerosol release prediction and tracking system would be designed, fabricated, and tested. The system would gather real time atmospheric data and input it into a real time atmospheric model that could be used for plume predition and tracking. The system would be able to be quickly deployed by aircraft to points of interest or positioned for deployment by vehicles. The system would provide three dimensional (u, v, and w) wind vector data, inversion height measurements, surface wind information, classical weather station data, and solar radiation. The on-board real time computer model would provide the prediction of the behavior of plumes and released aerosols.

    Full Text Available This article examines how the the fight against international terrorism, as a new organising principle in U.S. foreign policy and security policy, has conditioned and modified the American conception of and strategy for combatting nuclear arms proliferation. On the one hand, it analyses the concepts of “axis of evil” or “rogue states” as instruments of automatic and forced connection between international terrorism and nuclear armsproliferating states. On the other hand, it also deals with the changes in American nonproliferation and disarmament strategy, characterised by a distrust towards international cooperation and a clear preference for using means of a unilateral nature, which challenge, and even scorn, international institutions and the rules of international law in this area.

EO 9 (Lanasan LT as NPE-1 and EO 40 (Disponil AA P43 as NPE-2 were selected with the purpose to evaluate the influence of hydrophobicity of nonionic surfactants on wool dyeing efficiency. Anionic C.I. Acid Orange 7 dye was used to carry out an experiment in dyeing of wool fibre at 30 °C or 60 °C temperature using wool fabric which was prepared for dyeing by extraction of the lipid materials soluble in chloroform and methanol mixture. The surfactant with a shorter hydrophilic chain (NPE-1 intensified the adsorption of the dye. This fact allowed to presume that the dye diffusion into wool fibre might be influenced by hydrophobic interaction between the surfactant and hydrophobic sites of wool fibre. The results of surfactants adsorption showed that the interaction of NPE-2 with the fibre was weak as compared to that of NPE-1. The results of the investigation suggest that the ethoxylated nonylphenol of a lower hydrophility index might interact with the active sites of wool fibre more intensively than that of a higher index of hydrophility.http://dx.doi.org/10.5755/j01.ms.17.3.596

    The goal of the Grid is to provide a coherent access to distributed computing resources. All LHC experiments are using several Grid infrastructures and a variety of the middleware flavors. Due to the complexity and heterogeinity of a distributed system the monitoring represents a challenging task. Independently of the underlying platform , the experiments need to ave a complete and uniform picture of their activities on the Grid ideally seen by the users as a single powerful computing resource. Overall operation of the infrastructure used by experiments is defined both by the quality of the Grid and the quality of the tools and services developed/used by the experiments. Correspondingly the required monitoring information should combine both Grid-related and experiment/application specific data. On the other hand, users of the LHC experiments have various roles and need different levels of details regarding monitoring data. The paper will focus on the Grid monitoring from the experiment/user perspectives with...

  5. Atmospheric Model Effects on Infrasound Source Inversion from the Source Physics Experiments

    Science.gov (United States)

    Preston, L. A.; Aur, K. A.

    2016-12-01

    The Source Physics Experiments (SPE) consist of a series of underground explosive shots at the Nevada National Security Site (NNSS) designed to gain an improved understanding of the generation and propagation of physical signals in the near and far field. Characterizing the acoustic and infrasound source mechanism from underground explosions is of great importance in non-proliferation activities. To this end we perform full waveform source inversion of infrasound data collected from SPE shots at distances from 300 m to 1 km and frequencies up to 20 Hz. Our method requires estimating the state of the atmosphere at the time of each shot, computing Green's functions through these atmospheric models, and subsequently inverting these signals in the frequency domain to obtain a source time function. To estimate the state of the atmosphere at the time of the shot, we utilize two different datasets: North American Regional Reanalysis data, a comprehensive but lower resolution dataset, and locally obtained sonde and surface weather observations. We synthesize Green's functions through these atmospheric models using Sandia's moving media acoustic propagation simulation suite. These models include 3-D variations in topography, temperature, pressure, and wind. We will compare and contrast the atmospheric models derived from the two weather datasets and discuss how these differences affect computed source waveforms and contribute to modeling uncertainty.

    The Structural Assembly Demonstration Experiment concept is to erect a hybrid deployed/assembled structure as an early space experiment in large space structures technology. The basic objectives can be broken down into three generic areas: (1) by performing assembly tasks both in space and in neutral buoyancy simulation, a mathematical basis will be found for the validity conditions of neutral buoyancy, thus enhancing the utility of water as a medium for simulation of weightlessness; (2) a data base will be established describing the capabilities and limitations of EVA crewmembers, including effects of such things as hardware size and crew restraints; and (3) experience of the M.I.T. Space Systems Lab in neutral buoyancy simulation of large space structures assembly indicates that the assembly procedure may create the largest loads that a structure will experience during its lifetime. Data obtained from the experiment will help establish an accurate loading model to aid designers of future space structures.

    1986-10-01

    The frequency of occurrence of behavioral estrus without subsequent development of functional luteal tissue (termed nonpuberal estrus, NPE), was determined in 43 Simmental X Hereford-Brahman heifers. Blood samples were collected weekly from the start of the study to first behavioral estrus and then daily from d 1 (d 0 = estrus) through d 14 following first and subsequently observed estrous behaviors. All blood samples were analyzed for serum progesterone (P4) concentrations by radioimmunoassay. More heifers (62.8%) exhibited NPE than had luteal development after their first behavioral estrus (37.2%). There was a tendency for fewer light-weight heifers (less than or equal to 240 kg at the start of the experiment) to exhibit a puberal first estrus compared with the heavy-weight (greater than 240 kg at the start of the experiment) heifers (31.2% vs 68.8%, respectively; P = .12). Heifers that had a puberal first estrus were older (376 +/- 12 d vs 334 +/- 9 d, P less than .05) compared with heifers that had NPE. Weight at first behavioral estrus was similar between heifers that had a puberal first estrus and those that had NPE (298 +/- 8 kg and 289 +/- 6 kg, respectively). More heifers that had a puberal first estrus also had an elevation in serum P4 concentrations before that first estrus (64.3% vs 20.0%, P less than .05), and the serum P4 elevation was greater (2.5 +/- .4 ng vs 1.2 +/- .1 ng, P less than .05) than heifers that had NPE. We have concluded from these results that NPE is a common occurrence in heifers approaching puberty.(ABSTRACT TRUNCATED AT 250 WORDS)

    Popper's original thought experiment probed some fundamental and subtle rules of quantum mechanics. Two recent experiments have tested Popper's hypothesis, but they seem to give contrasting results and one suggests a violation of Heisenberg's uncertainty principle. The equations governing these two experiments and Popper's thought experiment will be derived from basic principles. The experimental constants will be inputted and it will show that the two experiments agree with each other. It will be shown that no uncertainty relations are violated and that Popper's thought experiment was fundamentally flawed.

    The personal view for the next to the next neutrino detector, the ultimate experiment, is discussed. Considering the size, cost and head winds against the basic science, the ultimate experiment will be the only experiment in the world. Here two such experiments one for the neutrino oscillation and the other for the double beta decay were discussed. The ultimate experiment needs to include a bread and butter science and to have a discovery potential for an unexpected phenomenon. There are many technical challenges and international co-operations are absolutely necessary.

    We describe how virtual experiments can be utilized in a learning design that prepares students for hands-on experiments at large-scale facilities. We illustrate the design by showing how virtual experiments are used at the Niels Bohr Institute in a master level course on neutron scattering....... In the last week of the course, students travel to a large-scale neutron scattering facility to perform real neutron scattering experiments. Through student interviews and survey answers, we argue, that the virtual training prepares the students to engage more fruitfully with experiments by letting them focus...... on physics and data rather than the overwhelming instrumentation. We argue that this is because they can transfer their virtual experimental experience to the real-life situation. However, we also find that learning is still situated in the sense that only knowledge of particular experiments is transferred...

  13. Experiments with Individual Photons

    Beck, Mark

    2004-05-01

    I describe several different experiments we have performed with individual photons. For example, while well known experiments involving phenomena such as the photoelectric effect and Compton scattering strongly suggest the existence of photons, they do not prove the existence of light quanta. To prove the existence of light quanta one must perform an experiment whose results cannot be explained using classical waves. We have performed such an experiment--it demonstrates the localization of light quanta by showing that a single photon only goes one way when it leaves a beamsplitter [1]. In a second experiment we demonstrate that this single photon will interfere with itself when it transits an interferometer. The experiments have been performed by undergraduates, and the goal of this project is to develop a series of experiments exploring fundamental aspects of quantum mechanics for an undergraduate teaching lab.

  15. Popper's Thought Experiment Reinvestigated

    Science.gov (United States)

    Richardson, Chris; Dowling, Jonathan

    2012-02-01

    Karl Popper posed an interesting thought experiment in 1934. With it, he meant to question the completeness of quantum mechanics. He claimed that the notion of quantum entanglement leads to absurd scenarios that cannot be true in real life and that an implementation of his thought experiment would not give the results that QM predicts. Unfortunately for Popper, it has taken until recently to perform experiments that test his claims. The results of the experiments do not refute QM as Popper predicted, but neither do they confirm what Popper claimed QM predicted. Kim and Shih implemented Popper's thought experiment in the lab. The results of the experiment are not clear and have instigated many interpretations of the results. The results show some correlation between entangled photons, but not in the way that Popper thought, nor in the way a simple application of QM might predict. A ghost-imaging experiment by Strekalov, et al. sheds light on the physics behind Popper's thought experiment, but does not try to directly test it. I will build the physics of Popper's thought experiment from the ground up and show how the results of both of these experiments agree with each other and the theory of QM, but disprove Popper.

  16. Experiment, right or wrong

    CERN Document Server

    Franklin, Allan

    2008-01-01

    In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

  12. USML-1 Glovebox experiments

    Science.gov (United States)

    Naumann, Robert J.

    1995-01-01

    This report covers the development of and results from three experiments that were flown in the Materials Science Glovebox on USML-1: Marangoni convection in Closed Containers (MCCC), Double Float Zone (DFZ), and Fiber Pulling in Microgravity (FPM). The Glovebox provided a convenient, low cost method for doing simple 'try and see' experiments that could test new concepts or elucidate microgravity phenomena. Since the Glovebox provided essentially one (or possibly two levels of confinement, many of the stringent verification and test requirements on the experiment apparatus could be relaxed and a streamlined test and verification plan for flight qualification could be implemented. Furthermore, the experiments were contained in their own carrying cases whose external configurations could be identified early in the integration sequence for stowage considerations while delivery of the actual experiment apparatus could be postponed until only a few months before flight. This minimized the time fluids must be contained and reduced the possibility of corrosive reactions that could ruin the experiment. In many respects, this exercise was as much about developing a simpler, cheaper way of doing crew-assisted science as it was about the actual scientific accomplishments of the individual experiments. The Marangoni Convection in Closed Containers experiment was designed to study the effects of a void space in a simulated Bridgman crystal growth configuration and to determine if surface tension driven convective flows that may result from thermal gradients along any free surfaces could affect the solidification process. The Fiber Pulling in Microgravity experiment sought to separate the role of gravity drainage from capillarity effects in the break-up of slender cylindrical liquid columns. The Stability of a Double Float Zone experiment explored the feasibility of a quasi-containerless process in which a solidifying material is suspended by two liquid bridges of its own melt.

    2007-02-01

    Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention.

    The three eggs experiment concerns 37 pre-service science teachers’ predictions about the impact shapes of three uncooked eggs dropped from different heights. This experiment looks at energy transformation from potential to kinetic energy, where the smaller parts of the egg shell spread far from the center of the impact. This experience encouraged the pre-service science teachers to use their familiar models, such as a fried egg, omelet, puddle, dropping or explosions, to explain their predictions. These models from everyday life presented can be used as a tool to explain unfamiliar phenomena.

    The Red Sage campaign is a series of subcritical dynamic plutonium experiments designed to measure ejecta. Nightshade, the first experiments in Red Sage scheduled for fiscal year 2019, will measure the amount of ejecta emission into vacuum from a double-­shocked plutonium surface. To address the major technical risks in Nightshade, a Level 2 milestone was developed for fiscal year 2016. Silverleaf, a series of four experiments, was executed at the Los Alamos National Laboratory in July and August 2016 to demonstrate a prototype of the Nightshade package and to satisfy this Level 2 milestone. This report is documentation that Red Sage Level 2 milestone requirements were successfully met.

    1992-01-01

    Ways in which heat is useful in organic synthesis experiments are described, and experiments on the hydrothermal destruction and synthesis of organic compounds are discussed. It is pointed out that, if heat can overcome kinetic barriers to the formation of metastable states from reduced or oxidized starting materials, abiotic synthesis under hydrothermal conditions is a distinct possibility. However, carefully controlled experiments which replicate the descriptive variables of natural hydrothermal systems have not yet been conducted with the aim of testing the hypothesis of hydrothermal organic systems.

    Full Text Available History of philosophy is built upon rigid discrimination between various human experiences. Human experiences are divided mainly into two major experiences: Perceptual and intelectual. Perceptual experience is deined by empiricism as an aposteriori experience of empirical sensations. Meanwhile, rationalism claims that the only acceptable experience is apriori experience of intelectual object (natural laws, mathematical equations and logical operations. There is no other experience outside those two philosophical account of experiences. All other experiences must be subsumed either within perceptual or intelectual experience.

    Full Text Available In this article we wish to introduce and discuss a theoretical framework for a possible conceptualisation of the differences between reading a printed book and listening to an audiobook. We tend to introduce similarities and differences between reading with the eyes and reading with the ears, implying that we should not discuss the audiobook experience as a remediation of the printed book experience only, but as an entirely different experience that could be conceptualised in continuation of mobile listening practises. As a methodological strategy we will emphasise the differences between the literary practices, reading with the eyes and reading with the ears. These different perspectives on reading are used to accentuate the distinct experiences, and future thorough analyses in continuation of this framework would appear much more complex and connected than in the present article.

    Every 21st century student is expected to develop science literacy skills. As this is not part of Serbian national curriculum yet, we decided to introduce it with this project. Experiment-o-mania provides students to experience science in different and exciting way. It makes opportunity for personalized learning offering space and time to ask (why, where, how, what if) and to try. Therefore, we empower young people with skills of experimenting, and they love science back. They ask questions, make hypothesis, make problems and solve them, make mistakes, discuss about the results. Subsequently this raises the students' interest for school curriculum. This vision of science teaching is associated with inquiry-based learning. Experiment-o-mania is the unique and recognizable teaching methodology for the elementary school Drinka Pavlović, Belgrade, Serbia. Experiment-o-mania implies activities throughout the school year. They are held on extra class sessions, through science experiments, science projects or preparations for School's Days of science. Students learn to ask questions, make observations, classify data, communicate ideas, conduct experiments, analyse results and make conclusions. All science teachers participate in designing activities and experiments for students in Experiment-o-mania teaching method. But they are not alone. Teacher of fine arts, English teachers and others also take part. Students have their representatives in this team, too. This is a good way to blend knowledge among different school subject and popularize science in general. All the experiments are age appropriate and related to real life situations, local community, society and the world. We explore Fibonacci's arrays, saving energy, solar power, climate change, environmental problems, pollution, daily life situations in the country or worldwide. We introduce great scientists as Nikola Tesla, Milutin Milanković and sir Isaac Newton. We celebrate all relevant international days, weeks

    Radiochemical experiments have been crucial to solar neutrino research. Even today, they provide the only direct measurement of the rate of the proton-proton fusion reaction, p + p --> d + e^+ + nu_e, which generates most of the Sun's energy. We first give a little history of radiochemical solar neutrino experiments with emphasis on the gallium experiment SAGE -- the only currently operating detector of this type. The combined result of all data from the Ga experiments is a capture rate of 67.6 +/- 3.7 SNU. For comparison to theory, we use the calculated flux at the Sun from a standard solar model, take into account neutrino propagation from the Sun to the Earth and the results of neutrino source experiments with Ga, and obtain 67.3 ^{+3.9}_{-3.5} SNU. Using the data from all solar neutrino experiments we calculate an electron neutrino pp flux at the earth of (3.41 ^{+0.76}_{-0.77}) x 10^{10}/(cm^2-s), which agrees well with the prediction from a detailed solar model of (3.30 ^{+0.13} _{-0.14}) x 10^{10}/(cm^...

    Karapanos, Evangelos; Hassenzahl, Marc

    2009-01-01

    This paper presents iScale, a survey tool that aims at eliciting users' experiences with a product from memory. iScale employs sketching in imposing a process in the reconstruction of one's experiences. Two versions of iScale, the Constructive and the Value-Account iScale, were motivated by two distinct theories on how people reconstruct emotional experiences from memory. These two versions were tested in two separate studies. Study 1 aimed at providing qualitative insight into the use of iScale and compared its performance to that of free-hand sketching. Study 2 compared the two iScale versions to a control condition: that of reporting one's experiences without employing any form of sketching. Significant differences between iScale and the "no-sketching" tool were found. Overall, iScale resulted in a) an increase in the number of experience reports that subjects provided, b) an increase in the amount of contextual information for the reported experiences, and c) an increase in subjects' accuracy in recalling...

  12. Experiments in computing: a survey.

    Science.gov (United States)

    Tedre, Matti; Moisseinen, Nella

    2014-01-01

    Experiments play a central role in science. The role of experiments in computing is, however, unclear. Questions about the relevance of experiments in computing attracted little attention until the 1980s. As the discipline then saw a push towards experimental computer science, a variety of technically, theoretically, and empirically oriented views on experiments emerged. As a consequence of those debates, today's computing fields use experiments and experiment terminology in a variety of ways. This paper analyzes experimentation debates in computing. It presents five ways in which debaters have conceptualized experiments in computing: feasibility experiment, trial experiment, field experiment, comparison experiment, and controlled experiment. This paper has three aims: to clarify experiment terminology in computing; to contribute to disciplinary self-understanding of computing; and, due to computing's centrality in other fields, to promote understanding of experiments in modern science in general.

    We present the design and characterization of the POLARBEAR experiment. POLARBEAR will measure the polarization of the cosmic microwave background (CMB) on angular scales ranging from the experiment's 3.5 arcminute beam size to several degrees. The experiment utilizes a unique focal plane of 1,274 antenna-coupled, polarization sensitive TES bolometers cooled to 250 milliKelvin. Employing this focal plane along with stringent control over systematic errors, POLARBEAR has the sensitivity to detect the expected small scale B-mode signal due to gravitational lensing and search for the large scale B-mode signal from inflationary gravitational waves. POLARBEAR was assembled for an engineering run in the Inyo Mountains of California in 2010 and was deployed in late 2011 to the Atacama Desert in Chile. An overview of the instrument is presented along with characterization results from observations in Chile.

I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which...... was in a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology.

    The Insertable B-Layer (IBL) is the inner most pixel layer in the ATLAS experiment, which was installed at 3.3 cm radius from the beam axis in 2014 to improve the tracking performance. To cope with the high radiation and hit occupancy due to proximity to the interaction point, a new read-out chip and two different silicon sensor technologies (planar and 3D) have been developed for the IBL. After the long shut-down period over 2013 and 2014, the ATLAS experiment started data-taking in May 2015 for Run-2 of the Large Hadron Collider (LHC). The IBL has been operated successfully since the beginning of Run-2 and shows excellent performance with the low dead module fraction, high data-taking efficiency and improved tracking capability. The experience and challenges in the operation of the IBL is described as well as its performance.

    1996-12-01

    Flavorings in foods and fragrances in personal care products is a topic often discussed in chemistry classes designed for the general education of non-science majors. A laboratory experiment has been designed to accompany the lecture topic. Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell. Students are permitted to create their own fragrance based on the results of the experiment. Student response has been favorable. The experiment rectifies misconceptions students have about structure and odor, and gives positive reinforcement to the lecture material.

  2. Experiments in Particle Astrophysics

    2004-07-01

    During the last decade, the field of what is currently called particle astrophysics (that I prefer to the shaky neologism astroparticle physics) has experienced a surprising growth. It is interesting to understand why the cosmic rays, the poor man's accelerator not no long ago, are becoming the object of scrutiny for a continuously growing community of theoreticians and experimentalists. In this article, we made an arbitrary choice of a small number of experiments to illustrate today's state of the art and the future perspectives in this domain. Our choice is based on three facts: the objects detected in each experiment are different, all the selected experiments are in their starting phase and all are spectacular for various reasons. Our aim is to convince the reader of the enormous discovery potential of these ongoing projects and share with him the excitement experienced by those involved in them. (Author) 37 refs.

    The oceans are an equal partner with the atmosphere in the global climate system. The World Ocean Circulation Experiment is presently being implemented to improve ocean models that are useful for climate prediction both by encouraging more model development but more importantly by providing quality data sets that can be used to force or to validate such models. WOCE is the first oceanographic experiment that plans to generate and to use multiparameter global ocean data sets. In order for WOCE to succeed, oceanographers must establish and learn to use more effective methods of assembling, quality controlling, manipulating and distributing oceanographic data.

    In 1977, in a record-time of 9 months, the magnets of the g-2 experiment were modified and used to build a proton/antiproton storage ring: the "Initial Cooling Experiment" (ICE). It served for the verification of the cooling methods to be used for the "Antiproton Project". Stochastic cooling was proven the same year, electron cooling followed later. Also, with ICE the experimental lower limit for the antiproton lifetime was raised by 9 orders of magnitude: from 2 microseconds to 32 hours. For its previous life as g-2 storage ring, see 7405430.

    Following the Super-Kamiokande findings on atmospheric neutrinos, accelerator neutrinos have started to be exploited to confirm the indication for neutrino oscillations and perform more complete measurements of the mass differences and mixing parameters. In Europe, the long baseline beam CERN Neutrino to Gran Sasso CNGS is aimed at direct appearance searches of nu /sub mu / to nu /sub tau /. The OPERA experiment in Gran sasso will use photographic emulsions in a large hybrid detector to point at nu , interactions coming from the CNGS beam in a "zero background" approach. The principles of the experiment and its projected performances are described. (12 refs).

    Belief elicitation in economics experiments usually relies on paying subjects according to the accuracy of stated beliefs in addition to payments for other decisions. Such incentives, however, allow risk-averse subjects to hedge with their stated beliefs against adverse outcomes of other decisions...... in the experiment. This raises two questions: (i) can we trust the existing belief elicitation results, (ii) can we avoid potential hedging confounds? Our results instill confidence regarding both issues. We propose an experimental design that eliminates hedging opportunities, and use this to test for the empirical...

    Atmospheric, solar, reactor and accelerator neutrino oscillation experiments have measured $ m_{12}^{2}$, sin2 12, $| m_{23}^{2} |$ and sin2 223. The next stage of the oscillation studies should be the observation of a finite sin2 213. If a non-zero sin2 213 is observed, the subsequent goals should be the observation of the CP violation and the determination sign of $ m_{23}^{2}$. Possible future neutrino oscillation experiments that could assess these questions are discussed.

  5. The Transgender Military Experience

    Full Text Available Although there have been studies that focus on the experiences of the gay and lesbian population serving in the United States military, few have focused on the experience of active duty transgender service members. Transgender individuals transgress the binary conception of gender by deviating from societal gender norms associated with assigned sex at birth. The Department of Defense has set policies and standards that reflect a binary conception of gender, with a focus on conformity. We argue that able-bodied gender variant service personnel are just as capable of serving their country as anyone else. Because of the repercussions associated with active duty transgender military personnel, our sample is small and involves nine clandestine service members and two international service members who wanted to share their stories from a different perspective. Snowball sampling was aimed at finding current active duty and reserve transgender service members. Using a combination of telephone interviews and questionnaires, data were collected from active duty transgender service personnel throughout the United States and two from international militaries that allow transgender people to serve. Data collection focused on the overall experiences of the participants along with questions regarding workplace discrimination, suggestions for policy changes, and their views about the overturn of Don’t Ask, Don’t Tell. Our findings add to a growing source of information about the transgender military experience in the U.S. armed forces and the importance of overturning discriminatory workplace policies that negatively impact transgender service members.

    An experiment proposed by Karl Popper is considered by many to be a crucial test of quantum mechanics. Although many loopholes in the original proposal have been pointed out, they are not crucial to the test. We use only the standard interpretation of quantum mechanics to point out what is fundamentally wrong with the proposal, and demonstrate that Popper's basic premise was faulty.

    2007-01-01

    The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

    2013-12-15

    The OLYMPUS experiment was designed to measure the ratio between the positron-proton and electron-proton elastic scattering cross sections, with the goal of determining the contribution of two-photon exchange to the elastic cross section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, {mu}{sub p}G{sup p}{sub E}/G{sup p}{sub M}, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25 -75 . Symmetric Moeller/Bhabha calorimeters at 1.29 and telescopes of GEM and MWPC detectors at 12 served as luminosity monitors. A total luminosity of approximately 4.5 fb{sup -1} was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

  3. Electrophoresis experiments in microgravity

    Science.gov (United States)

    Snyder, Robert S.; Rhodes, Percy H.

    1991-01-01

    The use of the microgravity environment to separate and purify biological cells and proteins has been a major activity since the beginning of the NASA Microgravity Science and Applications program. Purified populations of cells are needed for research, transplantation and analysis of specific cell constituents. Protein purification is a necessary step in research areas such as genetic engineering where the new protein has to be separated from the variety of other proteins synthesized from the microorganism. Sufficient data are available from the results of past electrophoresis experiments in space to show that these experiments were designed with incomplete knowledge of the fluid dynamics of the process including electrohydrodynamics. However, electrophoresis is still an important separation tool in the laboratory and thermal convection does limit its performance. Thus, there is a justification for electrophoresis but the emphasis of future space experiments must be directed toward basic research with model experiments to understand the microgravity environment and fluid analysis to test the basic principles of the process.

  10. Parabolic aircraft solidification experiments

    Workman, Gary L. (Principal Investigator); Smith, Guy A.; OBrien, Susan

    1996-01-01

    A number of solidification experiments have been utilized throughout the Materials Processing in Space Program to provide an experimental environment which minimizes variables in solidification experiments. Two techniques of interest are directional solidification and isothermal casting. Because of the wide-spread use of these experimental techniques in space-based research, several MSAD experiments have been manifested for space flight. In addition to the microstructural analysis for interpretation of the experimental results from previous work with parabolic flights, it has become apparent that a better understanding of the phenomena occurring during solidification can be better understood if direct visualization of the solidification interface were possible. Our university has performed in several experimental studies such as this in recent years. The most recent was in visualizing the effect of convective flow phenomena on the KC-135 and prior to that were several successive contracts to perform directional solidification and isothermal casting experiments on the KC-135. Included in this work was the modification and utilization of the Convective Flow Analyzer (CFA), the Aircraft Isothermal Casting Furnace (ICF), and the Three-Zone Directional Solidification Furnace. These studies have contributed heavily to the mission of the Microgravity Science and Applications' Materials Science Program.

  16. Transformations of emotional experience.

    Science.gov (United States)

    de Cortiñas, Lia Pistiner

    2013-06-01

    In this paper the author approaches mental pain and the problems in a psychoanalytic treatment of patients with difficulties in the psychic transformation of their emotional experiences. The author is interested in the symbolic failure related to the obstruction of development of phantasies, dreams, dream-thoughts, etc. She differentiates symbolization disturbances related to hypertrophic projective identification from a detention of these primitive communications and emotional isolation. She puts forward the conjecture that one factor in the arrest of this development is the detention of projective identifications and that, when this primitive means of communication is re-established in a container-contained relationship of mutual benefit, this initiates the development of a symbolization process that can replace the pathological 'protection'. Another hypothesis she develops is that of inaccessible caesuras that, associated with the detention of projective identification, obstruct any integrative or interactive movement. This caesura and the detention of projective identifications affect mental functions needed for dealing with mental pain. The personality is left with precarious mental equipment for transforming emotional experiences. How can a psychoanalytical process stimulate the development of creative symbolization, transforming the emotional experiences and leading towards mental growth? The author approaches the clinical problem with the metaphor of the psychic birth of emotional experience. The modulation of mental pain in a container-contained relationship is a central problem for the development of the human mind. For discovering and giving a meaning to emotional experience, the infant depends on reverie, a function necessary in order to develop an evolved consciousness capable of being aware, which is different from the rudimentary consciousness that perceives but does not understand. The development of mature mental equipment is associated with the

    1992-01-01

    The serious scientific debate about spontaneous generation which raged for centuries reached a climax in the nineteenth century with the work of Spallanzani, Schwann, Tyndall, and Pasteur. These investigators demonstrated that spontaneous generation from dead organic matter does not occur. Although no aspects of these experiments addressed the issue of whether organic compounds could be synthesized abiotically, the impact of the experiments was great enough to cause many investigators to assume that life and its organic compounds were somehow fundamentally different than inorganic compounds. Meanwhile, other nineteenth-century investigators were showing that organic compounds could indeed be synthesized from inorganic compounds. In 1828 Friedrich Wohler synthesized urea in an attempt to form ammonium cyanate by heating a solution containing ammonia and cyanic acid. This experiment is generally recognized to be the first to bridge the artificial gap between organic and inorganic chemistry, but it also showed the usefulness of heat in organic synthesis. Not only does an increase in temperature enhance the rate of urea synthesis, but Walker and Hambly showed that equilibrium between urea and ammonium cyanate was attainable and reversible at 100 C. Wohler's synthesis of urea, and subsequent syntheses of organic compounds from inorganic compounds over the next several decades dealt serious blows to the 'vital force' concept which held that: (1) organic compounds owe their formation to the action of a special force in living organisms; and (2) forces which determine the behavior of inorganic compounds play no part in living systems. Nevertheless, such progress was overshadowed by Pasteur's refutation of spontaneous generation which nearly extinguished experimental investigations into the origins of life for several decades. Vitalism was dealt a deadly blow in the 1950's with Miller's famous spark-discharge experiments which were undertaken in the framework of the Oparin

  18. LCLS The First Experiments

    Galayda, John N

    2003-02-10

    The Scientific Advisory Committee (SAC) for the Linac Coherent Light Source (LCLS) has selected six scientific experiments for the early phase of the project. The LCLS, with proposed construction in the 2003-2006 time frame, has been designed to utilize the last third of the existing Stanford Linear Accelerator Center (SLAC) linac. The linac produces a high-current 5-15 GeV electron beam that is bunched into 230 fs slices with a 120 Hz repetition rate. When traveling through a sufficiently long (of order of 100 m) undulator, the electron bunches will lead to self amplification of the emitted x-ray intensity constituting an x-ray free electron laser (XFEL). If funded as proposed, the LCLS will be the first XFEL in the world, operating in the 800-8,000 eV energy range. The emitted coherent x-rays will have unprecedented brightness with 10{sup 12}-10{sup 13} photons/pulse in a 0.2-0.4% energy bandpass and an unprecedented time structure with a design pulse length of 230 fs. Studies are under way to reduce the pulse length to tens of femtoseconds. This document presents descriptions of the early scientific experiments selected by SAC in the spring of 2000. They cover a wide range of scientific fields. The experimental teams consist of many internationally recognized scientists who are excited about the unprecedented x-ray capabilities of LCLS that surely will lead to new scientific frontiers. More generally, this document serves to forward the scientific case for an accelerator-based XFEL source, as requested by the BESAC subpanel on Novel Coherent Light Sources, chaired by Stephen R. Leone. Two general classes of experiments are proposed for the LCLS. The first class consists of experiments where the x-ray beam is used to probe the sample without modifying it, as is done in most experiments at current synchrotron sources. In the second class, the LCLS beam is used to induce non-linear photo-processes or matter in extreme conditions. The same source can be used for

  20. Infrastructures as Ontological Experiments

    Full Text Available Ontology has recently gained renewed attention in science and technology studies and anthropology (e.g. Gad, Jensen and Winthereik 2015; Holbraad, Pedersen and Viveiros de Castro 2014; Woolgar and Lezaun 2013. Yet, it has a considerably longer pedigree than these recent debates might lead one to think. Experiments, of course, have long held the attention of sociologists, historians, and philosophers of science (Collins 1985; Gooding 1990; Shapin and Schaffer 1985. And infrastructures have been the focus of sustained inquiry in the sociology and history of technology (Bowker 1994; Hughes 1983. Once these terms are put into conjunction, however, each gets a somewhat different inflection. The following note briefly explores the conceptual purchase of considering infrastructures as ontological experiments.

  1. Quantum Gravity Experiments

    2015-10-01

    Full Text Available A new quantum gravity experiment is reported with the data confirming the generali- sation of the Schrödinger equation to include the interaction of the wave function with dynamical space. Dynamical space turbulence, via this interaction process, raises and lowers the energy of the electron wave function, which is detected by observing conse- quent variations in the electron quantum barrier tunnelling rate in reverse-biased Zener diodes. This process has previously been reported and enabled the measurement of the speed of the dynamical space flow, which is consistent with numerous other detection experiments. The interaction process is dependent on the angle between the dynamical space flow velocity and the direction of the electron flow in the diode, and this depen- dence is experimentally demonstrated. This interaction process explains gravity as an emergent quantum process, so unifying quantum phenomena and gravity. Gravitational waves are easily detected.

    In particle physics experiments, the discovery of increasingly more massive particles has brought deep understanding of the basic constituents of matter and of the fundamental forces among them. In order to explore Nature in its deepest elementary secrets, the Large Hadron Collider (LHC) was built at CERN, Geneva. The LHC provides the highest energy collisions in a laboratory, at very high rates to allow one to study very rare reactions. Two independent sophisticated huge instruments, called ATLAS and CMS detectors, are operated to explore in a most broad way the physics of these collisions. In addition to these two general-purpose detectors, smaller specialized experiments (LHCb, ALICE and some others) are collecting collision data as well.

    This article, as well as the book, investigates the ways in which new digital media may enhance the experience of the art-archive. Taken as a whole, the new media is a vital component of a 'transdisciplinary' and transformative field, a cultural landscape that is changing rapidly the conditions...... on paper but seldom succeeds in reality. Such websites often ignore the physical and social experience of a museum visit. Curiously, when they are most successful, websites often compete with the actual museum, possibly reducing the number of visitors and diluting the effect of seeing art first hand....... The book discusses the challenges of the archive and the (art)museum in the age of digital media. It is based upon documentation from a research project, MAP - Media Art Platform, that drew upon the talents and collaboration of many institutions, artists, programmers, art historians, designers and others...

    The Shooting Star Experiment (SSE) is designed to develop and demonstrate the technology required to focus the sun's energy and use the energy for inexpensive space Propulsion Research. Pictured is an engineering model (Pathfinder III) of the Shooting Star Experiment (SSE). This model was used to test and characterize the motion and deformation of the structure caused by thermal effects. In this photograph, alignment targets are being placed on the engineering model so that a theodolite (alignment telescope) could be used to accurately measure the deformation and deflections of the engineering model under extreme conditions, such as the coldness of deep space and the hotness of the sun as well as vacuum. This thermal vacuum test was performed at the X-Ray Calibration Facility because of the size of the test article and the capabilities of the facility to simulate in-orbit conditions

    A Gross Decontamination Experiment was conducted on various levels and surfaces of the TMI - Unit 2 reactor building in March 1982. The polar crane, D-rings, missile shields, refueling canals, refueling bridges, equipment, and elevations 305' and 347'-6'' were flushed with low pressure water. Additionally, floor surfaces on elevation 305' and floor surfaces and major pieces of equipment on elevation 347'-6'' were sprayed with high pressure water. Selective surfaces were decontaminated with a mechanical scrubber and chemicals. Strippable coating was tested and evaluated on equipment and floor surfaces. The effectiveness, efficiency, and safety of several decontamination techniques were established for the large, complex decontamination effort. Various decontamination equipment was evaluated and its effectiveness was documented. Decontamination training and procedures were documented and evaluated, as were the support system and organization for the experiment.

An antiproton annihilates a proton in the nucleus of a cancer cell, producing a pair of gamma rays, destroying the entire cell and some surrounding cells. Many fewer antiprotons are required in this treatment than in the equivalent proton hadron therapy, so there is less risk of healthy tissue damage.

    An experiment, proposed by Karl Popper, is considered by many, to be a crucial test of quantum mechanics. While many loop holes have been pointed out in the original proposal, it turned out that they are not crucial to the test. We point out what is fundamentally wrong with the proposal. Using just the standard interpretation of quantum mechanics, we demonstrate that Popper's basic premise was faulty.

    Employee-centric strategies have moved from employee satisfaction and brand awareness to employee "affinity" or "attachment." In today's marketplace, occupational health nurses understand that differentiation (i.e., the perception of uniqueness) is the direct result of superior employee interactions, which lead to better employee care, enduring employee relationships, loyal employees, and satisfied employers. What drives employees to occupational health nurse attachment? The answer is a passion for rising above the competition to create ideal employee experiences.

    Our experiments were involving inductive magnetic levitation. A Halbach array is a system in which a series of magnets is arranged in a manner such that the magnetic field is cancelled on one side of the array while strengthening the field on the other. We constructed two circular Halbach wheels, making the strong magnetic field on the outer rim of the ring. Such system is usually dubbed as an Electrodynamic Wheel (EDW). Rotating this wheel around a horizontal axis above a flat conducting surface should induce eddy currents in said surface through the variable magnetic flux. The eddy currents produce, in turn, their own magnetic fields which interact with the magnets of the EDW. We demonstrated that these interactions produce both drag and lift forces on the EDW which can theoretically be used for lift and propulsion of the EDW. The focus of our experiments is determining how to maximize the lift-to-drag ratio by the proper choice of the induction element. We will also describe our experiments with a rotating circular Halbach array having the strong magnetic field of about 1 T on the flat side of the ring, and acting as a hovercraft.

    Full Text Available There is a lack of research in health psychology on the subjective experience of adolescents with mental health disorders. The aim of this study was to explore the experience of depression and the journey into therapy of young people (YP diagnosed with depression. Semi-structured interviews were carried out with six YP (5 female, aged 15–19. Interviews were analyzed using Interpretative Phenomenological Analysis. The following four key themes were identified: “Suffering is experienced as overwhelming,” “An experience of loneliness and isolation,” “Struggling to understand the suffering,” and “Therapy as a last resort.” Reasons for a delay in accessing treatment were not knowing what is “normal,” the feeling that they have to deal with it by themselves, and/or the lack of a caring adult who supports the YP in getting help. The findings suggest the ongoing importance of reducing stigma and promoting mental health education for YP as well as parents, school staff, and health professionals.

    Following the discovery of neutrino oscillations by the Super-Kamiokande collaboration, recently awarded with the Nobel Prize, two generations of long baseline experiments had been setup to further study neutrino oscillations. The first generation experiments, K2K in Japan, Minos in the States and Opera in Europe, focused in confirming the Super-Kamiokande result, improving the precision with which oscillation parameters had been measured and demonstrating the ντ appearance process. Second generation experiments, T2K in Japan and very recently NOνA in the States, went further, being optimized to look for genuine three neutrino phenomena like non-zero values of θ13 and first glimpses to leptonic CP violation (LCPV) and neutrino mass ordering (NMO). The discovery of leptonic CP violation will require third generation setups, at the moment two strong proposals are ongoing, Dune in the States and Hyper-Kamiokande in Japan. This review will focus a little more in these future initiatives.

    A sequential design of experiments strategy is being developed and implemented that allows for adaptive learning based on incoming results as the experiment is being run. The plan is to incorporate these strategies for the NCCC and TCM experimental campaigns to be run in the coming months. This strategy for experimentation has the advantages of allowing new data collected during the experiment to inform future experimental runs based on their projected utility for a particular goal. For example, the current effort for the MEA capture system at NCCC plans to focus on maximally improving the quality of prediction of CO2 capture efficiency as measured by the width of the confidence interval for the underlying response surface that is modeled as a function of 1) Flue Gas Flowrate [1000-3000] kg/hr; 2) CO2 weight fraction [0.125-0.175]; 3) Lean solvent loading [0.1-0.3], and; 4) Lean solvent flowrate [3000-12000] kg/hr.

    In support of LLNL efforts to develop multiscale models of a variety of materials, we have performed a set of eight gas gun impact experiments on 2169 steel (21% Cr, 6% Ni, 9% Mn, balance predominantly Fe). These experiments provided carefully controlled shock, reshock and release velocimetry data, with initial shock stresses ranging from 10 to 50 GPa (particle velocities from 0.25 to 1.05 km/s). Both windowed and free-surface measurements were included in this experiment set to increase the utility of the data set, as were samples ranging in thickness from 1 to 5 mm. Target physical phenomena included the elastic/plastic transition (Hugoniot elastic limit), the Hugoniot, any phase transition phenomena, and the release path (windowed and free-surface). The Hugoniot was found to be nearly linear, with no indications of the Fe phase transition. Releases were non-hysteretic, and relatively consistent between 3- and 5-mmthick samples (the 3 mm samples giving slightly lower wavespeeds on release). Reshock tests with explosively welded impactors produced clean results; those with glue bonds showed transient releases prior to the arrival of the reshock, reducing their usefulness for deriving strength information. The free-surface samples, which were steps on a single piece of steel, showed lower wavespeeds for thin (1 mm) samples than for thicker (2 or 4 mm) samples. A configuration used for the last three shots allows release information to be determined from these free surface samples. The sample strength appears to increase with stress from ~1 GPa to ~ 3 GPa over this range, consistent with other recent work but about 40% above the Steinberg model.

    The Moon is, together with the Sun, the very first astronomical object that we experience in our life. As this is an exclusively visual experience, people with visual impairments need a different mode to experience it too. This statement is especially true when events, such as more and more frequent public observations of sky, take place. This is the reason why we are preparing a special package for visual impaired people containing three brand new items: 1. a tactile 3D Moon sphere in Braille with its paper key in Braille. To produce it we used imaging data obtained by NASA's mission Clementine, along with free image processing and 3D rendering software. In order to build the 3D small scale model funding by Europlanet and the Italian Ministry for Research have been used. 2. a multilingual web site for visually impaired users of all ages, on basic astronomy together with an indepth box about the Moon; 3. a book in Braille with the same content of the Web site mentioned above. All the items will be developed with the collaboration of visually impaired people that will check each step of the project and support their comments and criticism to improve it. We are going to test this package during the next International Observe the Moon Night event. After a first testing phase we'll collect all the feedback data in order to give an effective form to the package. Finally the Moon package could be delivered to all those who will demand it for outreach or educational goals.

  14. Situating Emotional Experience

    Full Text Available Psychological construction approaches to emotion suggest that emotional experience is situated and dynamic. Fear, for example, is typically studied in a physical danger context (e.g., threatening snake, but in the real world, it often occurs in social contexts, especially those involving social evaluation (e.g., public speaking. Understanding situated emotional experience is critical because adaptive responding is guided by situational context (e.g., inferring the intention of another in a social evaluation situation vs. monitoring the environment in a physical danger situation. In an fMRI study, we assessed situated emotional experience using a newly developed paradigm in which participants vividly imagine different scenarios from a first-person perspective, in this case scenarios involving either social evaluation or physical danger. We hypothesized that distributed neural patterns would underlie immersion in social evaluation and physical danger situations, with shared activity patterns across both situations in multimodal sensory regions and in circuitry involved in integrating salient sensory information, and with unique activity patterns for each situation type in coordinated large-scale networks that reflect situated responding. More specifically, we predicted that networks underlying the social inference and mentalizing involved in responding to a social threat (in regions that make up the default mode network would be reliably more active during social evaluation situations. In contrast, networks underlying the visuospatial attention and action planning involved in responding to a physical threat would be reliably more active during physical danger situations. The results supported these hypotheses. In line with emerging psychological construction approaches, the findings suggest that coordinated brain networks offer a systematic way to interpret the distributed patterns that underlie the diverse situational contexts characterizing

    During the 1979 Megagauss II conference the hypervelocity potential of railguns and the pulsed power technology needed to power them were discussed. Since then, many laboratories have initiated railgun R and D projects for a variety of potential applications. Los Alamos and Lawrence Livermore National Laboratories initiated a collaborative experimental railgun project which resulted in several successes in accelerating projectiles to high velocities, emphasized the limits on railgun operation, and indicated that the numerical modeling of railgun operation was in good agreement with the experiments.

    A fundamental obstacle to routine space access is the specific energy limitations associated with chemical fuels. In the case of vertical take-off, the high thrust needed for vertical liftoff and acceleration to orbit translates into power levels in the 10 GW range. Furthermore, useful payload mass fractions are possible only if the exhaust particle energy (i.e., exhaust velocity) is much greater than that available with traditional chemical propulsion. The electronic binding energy released by the best chemical reactions (e.g., LOX/LH2 for example, is less than 2 eV per product molecule (approx. 1.8 eV per H2O molecule), which translates into particle velocities less than 5 km/s. Useful payload fractions, however, will require exhaust velocities exceeding 15 km/s (i.e., particle energies greater than 20 eV). As an added challenge, the envisioned hypothetical RLV (reusable launch vehicle) should accomplish these amazing performance feats while providing relatively low acceleration levels to orbit (2-3g maximum). From such fundamental considerations, it is painfully obvious that planned and current RLV solutions based on chemical fuels alone represent only a temporary solution and can only result in minor gains, at best. What is truly needed is a revolutionary approach that will dramatically reduce the amount of fuel and size of the launch vehicle. This implies the need for new compact high-power energy sources as well as advanced accelerator technologies for increasing engine exhaust velocity. Electromagnetic acceleration techniques are of immense interest since they can be used to circumvent the thermal limits associated with conventional propulsion systems. This paper describes the Magnetohydrodynamic Augmented Propulsion Experiment (MAPX) being undertaken at NASA Marshall Space Flight Center (MSFC). In this experiment, a 1-MW arc heater is being used as a feeder for a 1-MW magnetohydrodynamic (MHD) accelerator. The purpose of the experiment is to demonstrate

    Despite a fall in the number of nuclear power plants under construction, the construction technology continues to improve and the new plants now being built in Asia are dramatically cutting lead times. These Asian projects are becoming the benchmark for what can be achieved in the construction of new nuclear plant. The article focuses on the Lungmen Advanced Boiling Water Reactor now under construction in Taiwan. Excavation started in early 1998 and commercial operation is expected in spring 2004. Lungmen's approach to construction of the plant was based on its experience in Japan: the approach is described.

    The Maryland Centrifugal Experiment (MCX) Project has investigated the concepts of centrifugal plasma confinement and stabilization of instabilities by velocity shear. The basic requirement is supersonic plasma rotation about a shaped, open magnetic field. Overall, the MCX Project attained three primary goals that were set out at the start of the project. First, supersonic rotation at Mach number upto 2.5 was obtained. Second, turbulence from flute interchange modes was found considerably reduced from conventional. Third, plasma pressure was contained along the field, as evidenced by density drops of x10 from the center to the mirror throats.

    We report the first quantum frequency downconversion experiment. Using the difference frequency generation process in a periodically poled lithium niobate waveguide, we successfully observed the phase-preserved frequency downconversion of a coherent pulse train with an average photon number per pulse of $<$1, from the 0.7-$\\mu$m visible wavelength band to the 1.3-$\\mu$m telecom band. We expect this technology to become an important tool for flexible photonic quantum networking, including the realization of quantum repeater systems over optical fiber using atom-photon entanglement sources for the visible wavelength bands.

    The Apollo 15 soil-mechanics experiment has offered greater opportunity for study of the mechanical properties of the lunar soil than previous missions, not only because of the extended lunar-surface stay time and enhanced mobility provided by the lunar roving vehicle (rover), but also because four new data sources were available for the first time. These sources were: (1) the self-recording penetrometer (SRP), (2) new, larger diameter, thin-walled core tubes, (3) the rover, and (4) the Apollo lunar-surface drill (ALSD). These data sources have provided the best bases for quantitative analyses thus far available in the Apollo Program.

    The present status of experimental solar neutrino research is reviewed. Updated results from the Homestake, Kamiokande, GALLEX and SAGE detectors all show a deficit when compared to recent standard solar model calculations. Two of these detectors, GALLEX and SAGE, have recently been checked with artificial {sup 51}Cr neutrino sources. It is shown that astrophysical scenarios to solve the solar neutrino problems are not favoured by the data. There is hope that the results of forthcoming solar neutrino experiments can provide the answers to the open questions. (author) 6 figs., 3 tabs., 36 refs.

    The CMS Tracker was repaired, recalibrated and commissioned successfully for the second run of Large Hadron Collider. In 2015 the Tracker performed well with improved hit efficiency and spatial resolution compared to Run I. Operations successfully transitioned to lower temperatures after commissioning environmental control and monitoring. This year the detector is expected to withstand luminosities that are beyond its design limits and will need a combined effort of both online and offline team to yield the high quality data that is required to reach our physics goals. We present the experience gained during the second run of the LHC and show the latest performance results of the CMS Tracker.

    Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that stirling machines are capable of reliable and lengthy operating lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and are not expected to operate for lengthy periods of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered. The record in this paper is not complete, due to the reluctance of some organizations to release operational data and because several organizations were not contacted. The authors intend to repeat this assessment in three years, hoping for even greater participation.

    The ELBE center for high power radiation sources is the largest user facility in the Helmholtz-Zentrum Dresden- Rossendorf. The facility is based on a 36 MeV superconducting RF Linac which can be operated up to 1.6 mA in cw mode. The electron beam is used to generate secondary radiation, such as infrared light (Free Electron Lasers), coherent THz radiation, MeV-Bremsstrahlung, fast neutrons and positrons for a wide range of basic research like semiconductor physics, nuclear astrophysics and radio biological investigations. Two high power laser systems (500 TW Ti:Sa laser, 2 PW diode pumped laser) are under construction for laser acceleration experiments and X-ray generation by Thomson scattering. The FELs are in operation since 2004 (mid-IR FEL, 4-22μm) and 2006 (far-IF FEL, 20-250μm). The fundamental features of the ELBE IR FELs, the FEL instrumentation and advanced beam diagnostics for the photon beam are described.

    Full Text Available Introduction: There is very little published literature about experience with osteoporosis treatment from our country. Materials and Methods: It is a retrospective analysis of first 50 patients enrolled in our clinic for osteoporosis. Postmenopausal women with T score of less than -2.5 or history suggestive fragility fracture with supportive bone mineral density (BMD were included. Patients having hypercalcemia, abnormal renal function, myeloma and on long-term steroids were also excluded. Results: Nearly 34% subjects were below the age of 60 years, 47% of subjects were between 60 and 70 years, whereas 18% were above 70 years. Nearly 6% had family history of osteoporosis s or history of osteoporotic fractures. Nearly 20% subjects had fracture prior to starting of any treatment. A total of 86% (40/46 had evidence of Vitamin D (VD deficiency. Nearly 80% of patients were treated with bisphosphonates, 12% were treated with injectable bisphosphonates, and 8% were treated with teriperatide. Nearly 16% patients had duration of more than 5 years of experience with bisphosphonates. Follow up BMD was available in 25 subjects. BMD had improved significantly in 68% of subjects. In 24% the BMD was stable (the change was less than least significant change (LSC. In 8% BMD had shown a significant decline while being on treatment. Conclusion: Postmenopausal osteoporosis occurs in relatively younger women in our country. Majority of them are VD deficient. Oral bisphosphonates is the most common used drug; it is fairly well tolerated and effective.

    2014-01-01

    NEXT (Neutrino Experiment with a Xenon TPC) is an experiment to search neutrinoless double beta decay processes (bb0nu) in Xe136. The NEXT technology is based in the use of time projection chambers operating at a typical pressure of 15 bar and using electroluminescence to amplify the signal (HPXE). The main advantages of the experimental technique are: a) excellent energy resolution; b) the ability to reconstruct the trajectory of the two electrons emitted in the decays, which further contributes to the suppression of backgrounds; c) scalability to large masses; and d) the possibility to reduce the background to negligible levels thanks to the barium tagging technology (BATA). The NEXT roadmap was designed in four stages: i) Demonstration of the HPXE technology with prototypes deploying a mass of natural xenon in the range of 1 kg, using the NEXT-DEMO (IFIC) and NEXT-DBDM (Berkeley) prototypes; ii) Characterisation of the backgrounds to the bb0nu signal and measurement of the bb2nu signal with the NEW detecto...

    2002-01-01

    The study of hyperfine interactions offers the possibility to use radioactive nuclei as probes in matter. The @g-@g perturbated angular correlation (PAC) technique following implantation has found widespread application in this field. At ISOLDE we have been investigating electric field gradients at impurities in non-cubic metals in an ongoing series of experiments. \\\\ \\\\ The small number of probe atoms necessary for these measurements make them also ideally suited for studies of surface problems like diffusion, structure and dynamics. Cd on a molybdenum O110? surface will be studied as first system. For this purpose 10|1|0~atoms of |1|1|1|mCd will be evaporated onto the clean surface and the electric field gradient for isolated adatoms on terrace sites will be determined by PAC. The UHV system constructed for such experiments at ISOLDE is shown in the schematic drawing. It is coupled to the beam line through differential pumping stations and contains standard surface treatment and analysis equipment.

    EBEX is a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background radiation. The measurements would probe the inflationary epoch that took place shortly after the big bang and would significantly improve constraints on the values of several cosmological parameters. EBEX is unique in its broad frequency coverage and in its ability to provide critical information about the level of polarized Galactic foregrounds which will be necessary for all future CMB polarization experiments. EBEX consists of a 1.5 m Dragone-type telescope that provides a resolution of less than 8 arcminutes over four focal planes each of 4 degree diffraction limited field of view at frequencies up to 450 GHz. The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave pla...

    1993-06-01

    The Advanced Liquid Feed Experiment (ALFE) is a Hitchhiker experiment flown on board the Shuttle of STS-39 as part of the Space Test Payload-1 (STP-1). The purpose of ALFE is to evaluate new propellant management components and operations under the low gravity flight environment of the Space Shuttle for eventual use in an advanced spacecraft feed system. These components and operations include an electronic pressure regulator, an ultrasonic flowmeter, an ultrasonic point sensor gage, and on-orbit refill of an auxiliary propellant tank. The tests are performed with two transparent tanks with dyed Freon 113, observed by a camera and controlled by ground commands and an on-board computer. Results show that the electronic pressure regulator provides smooth pressure ramp-up, sustained pressure control, and the flexibility to change pressure settings in flight. The ultrasonic flowmeter accurately measures flow and detects gas ingestion. The ultrasonic point sensors function well in space, but not as a gage during sustained low-gravity conditions, as they, like other point gages, are subject to the uncertainties of propellant geometry in a given tank. Propellant transfer operations can be performed with liquid-free ullage equalization at a 20 percent fill level, gas-free liquid transfer from 20-65 percent fill level, minimal slosh, and can be automated.

    Full Text Available It has been shown theoretically in the past that homogeneous dynamos may occur in electrically conducting fluids for various vortical velocity fields. Roberts (1972 investigated spatially periodic, infinitely extended fields of vortices which Busse (1978, 1992 confined to a finite cylindrical domain. Based on Busse's vortex arrangement a conceptual design for an experimental homogeneous dynamo has been developed and a test facility was setup at the Forschungszentrum Karlsruhe. The first experiments demonstrated that permanent dynamo action can be generated in a cylindrical container filled with liquid sodium in which by means of guide tubes counterrotating and countercurrent spiral vortices are established. The dynamo is self-exciting and the magnetic field saturates at a mean value for fixed super-critical flow rates. The instantaneous magnetic field fluctuates around this mean value by an order of about 5%. As predicted by theory the mode of the observed magnetic field is non-axisymmetric. In a series of experiments a phase- and a bifurcation diagram has been derived as a function of the spiral and axial flow rates.

    EBEX is a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background radiation. The measurements would probe the inflationary epoch that took place shortly after the big bang and would significantly improve constraints on the values of several cosmological parameters. EBEX is unique in its broad frequency coverage and in its ability to provide critical information about the level of polarized Galactic foregrounds which will be necessary for all future CMB polarization experiments. EBEX consists of a 1.5 m Dragone-type telescope that provides a resolution of less than 8 arcminutes over four focal planes each of 4. diffraction limited field of view at frequencies up to 450 GHz. The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave plate. EBEX is currently in the design and construction phase, and first light is scheduled for 2008.

    The Halogen Occultation Experiment (HALOE) uses solar occultation to measure vertical profiles of O3, HCl, HF, CH4, H2O, NO, NO2, aerosol extinction, and temperature versus pressure with an instantaneous vertical field of view of 1.6 km at the earth limb. Latitudinal coverage is from 80 deg S to 80 deg N over the course of 1 year and includes extensive observations of the Antarctic region during spring. The altitude range of the measurements extends from about 15 km to about 60-130 km, depending on channel. Experiment operations have been essentially flawless, and all performance criteria either meet or exceed specifications. Internal data consistency checks, comparisons with correlative measurements, and qualitative comparisons with 1985 atmospheric trace molecule spectroscopy (ATMOS) results are in good agreement. Examples of pressure versus latitude cross sections and a global orthographic projection for the September 21 to October 15, 1992, period show the utility of CH4, HF, and H2O as tracers, the occurrence of dehydration in the Antarctic lower stratosphere, the presence of the water vapor hygropause in the tropics, evidence of Antarctic air in the tropics, the influence of Hadley tropical upwelling, and the first global distribution of HCl, HF, and NO throughout the stratosphere. Nitric oxide measurements extend through the lower thermosphere.

  3. Experience in open markets

    Bachman, G.; Way, R.; O`Donnell, J.

    1997-05-01

    The topic of discussion in this session was experience in open markets. The session was led by Guido Bachman, President of the Independent Power Producers` Society of Alberta (IPPSA), assisted by panel members Richard Way, Director of Energy Risk Management at TransAlta, John O`Donnell, Professor of Finance at Michigan State University, and Kelly Lail, Manager of Power Acquisition at B.C. Hydro. Way spoke of the experiences with market restructuring in Alberta, describing the consultative and legislative process which determined the structure of the Alberta Power Pool (APP). The Pool began operations in January 1996. Currently there are 33 participants from generators, to distributors and marketers. Supply and demand are managed by APP by setting an hourly price based on offers and bids. Both generators and distributors get the hourly pool price, so the input price and export price of the pool are the same, however, generators and distributors are free to enter into `contract for difference` agreements. O`Donnell discussed the status of competition in Michigan. He stressed the importance of Ontario to the Michigan market, echoing the conviction of U.S. regulators that a freer economy works better. Kelly Lail spoke of the unbundling of B.C. Hydro into several generating, transmission and distribution companies in preparation for moving from exclusive service to exclusive wholesale competition. He predicted that the fierce competition will lead to a an industry shakeout, leaving only one big (B.C. Hydro) and a few niche players.

    Experiments with Ξ- atoms are proposed in order to study the nuclear interaction of Ξ hyperons. The production of Ξ- in the (K-,K+) reaction, the Ξ- stopping in matter, and its atomic cascade are incorporated within a realistic evaluation of the results expected for Ξ- x-ray spectra across the periodic table, using an assumed Ξ-nucleus optical potential Vopt. Several optimal targets for measuring the strong-interaction shift and width of the x-ray transition to the ``last'' atomic level observed are singled out: F, Cl, I, and Pb. The sensitivity of these observables to the parameters of Vopt is considered. The relevance of such experiments is discussed in the context of strangeness -2 nuclear physics and multistrange nuclear matter. Finally, with particular reference to searches for the H dibaryon, the properties of Ξ-d atoms are also discussed. The role of Stark mixing and its effect on S and P state capture of Ξ- by the deuteron together with estimates of the resulting probability for producing the H dibaryon are considered in detail.

    In nuclear reactors, a large number of antineutrinos are generated in the decay chains of the fission products; thus a survey of the antineutrino flux could provide valuable information related to the uranium and plutonium content of the core. This application generated interest by the IAEA in using antineutrino detectors as a potential safeguard tool. Here we present the Nucifer experiment, developed in France, by CEA and CNRS/IN2P3. The design of this new antineutrino detector has focused on safety, size reduction, reliability and high detection efficiency with a good background rejection. The Nucifer detector is currently taking data at the OSIRIS research reactor, inside CEA-Saclay. Presently, the ongoing analyses are considering the main sources of background for the antineutrino detection; the first antineutrino result is expected in 2013. A possible contribution to the understanding of the so called “reactor antineutrino anomaly” is also discussed. Finally, we present a brief description of the proposed experiments at very short baselines (VSBL) from reactors in France.

    Petascale High-Performance Computing (HPC) systems are among the largest systems in the world. Intrepid, one such system, is a 40,000 node, 556 teraflop Blue Gene/P system that has been deployed at Argonne National Laboratory. In this paper, we provide some background about the system and our administration experiences. In particular, due to the scale of the system, we have faced a variety of issues, some surprising to us, that are not common in the commodity world. We discuss our expectations, these issues, and approaches we have used to address them. HPC systems are a bellwether for computing systems at large, in multiple regards. HPC users are motivated by the need for absolute performance; this results in two important pushes. HPC users are frequently early adopters of new technologies and techniques. Successful technologies, like Infiniband, prove their value in HPC before gaining wider adoption. Unfortunately, this early adoption alone is not sufficient to achieve the levels of performance required by HPC users; parallelism must also be harnessed. Over the last 15 years, beowulf clustering has provided amazing accessibility to non-HPC-savvy and even non-technical audiences. During this time, substantial adoption of clustering has occurred in many market segments unrelated to computational science. A simple trend has emerged: the scale and performance of high-end HPC systems are uncommon at first, but become commonplace over the course of 3-5 years. For example, in early 2003, several systems on the Top500 list consisted of either 1024 nodes or 4096-8192 cores. In 2008, such systems are commonplace. The most recent generation of high-end HPC systems, so called petascale systems, are the culmination of years of research and development in research and academia. Three such systems have been deployed thus far. In addition to the 556 TF Intrepid system at Argonne National Laboratory, a 596 TF Blue Gene/L-based system has been deployed at Lawrence Livermore

    2012-12-01

    To commemorate the once-in-a-lifetime event of Arizona's hundredth birthday, the Centennial Commission and the Governor of Arizona envisioned a museum and companion website that would capture the state's history, celebrate its people, and embrace its future. Working with world-renowned museum designers, the state began to seek ideas from across Arizona to create plans for a journey of discovery through science and the humanities. The museum would introduce visitors to some of the people who nurtured the state through its early years and others who are innovating its tomorrows. Showcases would include the resources and experiences that shaped the state's history and are transforming its present day, highlighting the ingenuity that tamed the wild frontier and is envisioning Arizona's next frontiers through science and technology. The Arizona Experience (www.arizonaexperience.org) was initially intended to serve as the web presence for the physical museum, but as delays occurred with the physical museum, the site has quickly developed an identify of its own as an interactive, multimedia experience, reaching a wider audience with functions that would be difficult or expensive to produce in a museum. As leaders in scientific and technological innovation in the state, the Arizona Geological Survey was tasked with designing and creating the Arizona Experience site. The general themes remain the same; however, the site has added content and applications that are better suited to the online environment in order to create a rich, dynamic supplement to a physical museum experience. The website offers the features and displays of the future museum with the interactive nature and learning environment of the web. This provides an encyclopedic overview of the State of Arizona by subject matter experts in a manner that is free and open to the public and erases socio-economic, political, and physical boundaries. Over the Centennial Year of 2012 the site will release a new theme and

  8. Aesthetic experience of dance performances

    2012-01-01

    Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

    The paper explores how concrete urban experiments can challenge the pecuniary version of the experience city and stimulate a locally rooted and democratic version of an experience based city using heterotopias and concrete utopias as the link between top down planning and bottom up experiments...... in an emerging  experience city.  The first part of the article describes the growing and uncritical interest in the concepts of the ‘creative economy’, ‘creative class’ (Florida 2002) and their relationship with cultural production and economic growth (Bille & Schulze 2006), many of which, however, are driven...... mainly by political discourses producing more strategies and reports or commodified ´experience projects´ that are not rooted in real democratic experiments. Instead, the experience based development should emphasize a more object-oriented and a critical approach where real urban experiments link public...

    One of the purposes of the SQA effort at LLNL is to attempt to determine the 'goodness' of the research codes used for various scientific applications. Typically these are two and three dimensional multi-physics simulation and modeling codes. These legacy research codes are used for applciations such as atmospheric dispersion modeling and analysis and prediction of the performance of engineered systems. These codes are continually subjected to automated regression test suites consisting of verified and validated expected results. Code is managed in repositories. Experience level of developers is high in the knowledge domain, platforms, and languages used. Code size of the multi-physics code used in this study was 578,242 lines excluding comment and blank lines or 5538.7 function points. Languages were 70% C++, 20% C, and 10% Fortran. The code has 130 users and a development team of 14 and an embedded SQE. The code has achieved 100% prime feature test coverage, 73.6% functional test coverage, and 71.5% statement test coverage. The average cyclomatic complexity of the code was 6.25. The codes have evolved over 10 years. Research codes are challenging because there is a desire to balance agility with discipline as well as compliance with DOE standards. Agility is important to allow experimentation with new algorithms and addition of the latest physics features. Discipline is important to increase the quality of the codes. Automation of processes and defect prevention/detection are deployed throughout the software development process. Since resarch codes are a small segment of the software industry, not much information exists in terms of reliability studies on these types of codes. This paper describes attempts to determine the goodness of these research codes. Goodness defined as both correctness of the codes and their fault densities. Correctness is determined by user interviews, peer review; feature based automated testing, and coverage measurement. This

    This experiment observed the evolution of metabolite plumes from a human trapped in a simulation of a collapsed building. Ten participants took it in turns over five days to lie in a simulation of a collapsed building and eight of them completed the 6 h protocol while their breath, sweat and skin metabolites were passed through a simulation of a collapsed glass-clad reinforced-concrete building. Safety, welfare and environmental parameters were monitored continuously, and active adsorbent sampling for thermal desorption GC-MS, on-line and embedded CO, CO(2) and O(2) monitoring, aspirating ion mobility spectrometry with integrated semiconductor gas sensors, direct injection GC-ion mobility spectrometry, active sampling thermal desorption GC-differential mobility spectrometry and a prototype remote early detection system for survivor location were used to monitor the evolution of the metabolite plumes that were generated. Oxygen levels within the void simulator were allowed to fall no lower than 19.1% (v). Concurrent levels of carbon dioxide built up to an average level of 1.6% (v) in the breathing zone of the participants. Temperature, humidity, carbon dioxide levels and the physiological measurements were consistent with a reproducible methodology that enabled the metabolite plumes to be sampled and characterized from the different parts of the experiment. Welfare and safety data were satisfactory with pulse rates, blood pressures and oxygenation, all within levels consistent with healthy adults. Up to 12 in-test welfare assessments per participant and a six-week follow-up Stanford Acute Stress Response Questionnaire indicated that the researchers and participants did not experience any adverse effects from their involvement in the study. Preliminary observations confirmed that CO(2), NH(3) and acetone were effective markers for trapped humans, although interactions with water absorbed in building debris needed further study. An unexpected observation from the NH(3

    The main topic of this thesis is design and analysis of computer and simulation experiments and is dealt with in six papers and a summary report. Simulation and computer models have in recent years received increasingly more attention due to their increasing complexity and usability. Software...... that the sources of variation of the simulation model can be divided in two components corresponding to changes in the environmental factors (the uncontrollable factor settings) and to random variation. Moreover, the structure of the environmental effects can be estimated, which can be used to put the system...... in a more robust operating mode. The interpolation technique called Kriging is the topic of Paper F, which is a widely applied technique for building so called models-for-the-model (metamodels). We propose a method that handles both qualitative and quantitative factors, which is not covered by the standard...

    The determination of the neutrino mass is an open issue in modern particle physics and astrophysics. The direct mass measurement is the only theory-unrelated experimental tool capable to probe such quantity. The HOLMES experiment will measure the end-point energy of the electron capture decay of ^{163}Ho, aiming at a statistical sensitivity on the neutrino mass around 1 eV/c^2. In order to acquire the large needed statistics by keeping the pile-up contribution as low as possible, 1000 transition edge sensors will be readout simultaneously with the frequency domain readout, a multiplexing technique where the multiplex factor is only limited by the bandwidth of the available commercial fast digitizers. We outline here the HOLMES project with its technical challenges, and its status and perspectives.

    The SNO+ experiment is the follow-up to the Sudbury Neutrino Observatory (SNO). The heavy water that was in SNO will be replaced with a liquid scintillator of linear alkylbenzene (plus fluor). SNO+ has many physics goals including detecting pep and CNO solar neutrinos, detecting geo-neutrinos, studying reactor neutrino oscillations, serving as a supernova neutrino detector and carrying out a search for neutrinoless double beta decay by adding neodymium to the liquid scintillator. Since a large amount of 150Nd isotope can be added to SNO+, a competitive search would be possible, with sensitivity below 100 meV using natural Nd and sensitivity below 40 meV with enriched neodymium.

    Buchmann, Boris; 10.3150/10-BEJ328

    2012-01-01

    GARCH is one of the most prominent nonlinear time series models, both widely applied and thoroughly studied. Recently, it has been shown that the COGARCH model (which was introduced a few years ago by Kl\\"{u}ppelberg, Lindner and Maller) and Nelson's diffusion limit are the only functional continuous-time limits of GARCH in distribution. In contrast to Nelson's diffusion limit, COGARCH reproduces most of the stylized facts of financial time series. Since it has been proven that Nelson's diffusion is not asymptotically equivalent to GARCH in deficiency, in the present paper, we investigate the relation between GARCH and COGARCH in Le Cam's framework of statistical equivalence. We show that GARCH converges generically to COGARCH, even in deficiency, provided that the volatility processes are observed. Hence, from a theoretical point of view, COGARCH can indeed be considered as a continuous-time equivalent to GARCH. Otherwise, when the observations are incomplete, GARCH still has a limiting experiment, which we ...

    2010-01-01

    The cell radiation experiment system (CRES) is a perfused-cell culture apparatus, within which cells from humans or other animals can (1) be maintained in homeostasis while (2) being exposed to ionizing radiation during controlled intervals and (3) being monitored to determine the effects of radiation and the repair of radiation damage. The CRES can be used, for example, to determine effects of drug, radiation, and combined drug and radiation treatments on both normal and tumor cells. The CRES can also be used to analyze the effects of radiosensitive or radioprotectant drugs on cells subjected to radiation. The knowledge gained by use of the CRES is expected to contribute to the development of better cancer treatments and of better protection for astronauts, medical-equipment operators, and nuclear-power-plant workers, and others exposed frequently to ionizing radiation.

    The rapid expansion of remote sensing capability over the last two decades will take another major leap forward with the advent of the Earth Observing System (Eos). An approach is presented that will permit experiments and demonstrations in onboard information extraction. The approach is a non-intrusive, eavesdropping mode in which a small amount of spacecraft real estate is allocated to an onboard computation resource. How such an approach allows the evaluation of advanced technology in the space environment, advanced techniques in information extraction for both Earth science and information science studies, direct to user data products, and real-time response to events, all without affecting other on-board instrumentation is discussed.

    2007-01-01

    Creation of significant learning experiences follows basic steps of instructional design related to situational factors, goals and objectives, feedback and evaluation methods, teaching and learning activities, alignment of the preceding elements, and course evaluation. Goals should reflect what students will learn at the end of the course and what will still be with them several years later. Objectives should focus on learner performance, not teacher performance, and on behavior, not subject matter; there should be only one learning outcome per objective. Students learn more and retain their knowledge longer if they acquire it in an active rather than a passive manner. The situational factors, goals and objectives, feedback and evaluation, and teaching and learning activities should all reflect and support each other. The act of course evaluation closes the educational loop of design, implement, evaluate, and modify. (c) RSNA, 2007.

  19. Coblation Tonsillectomy our experience

    2014-03-01

    Full Text Available Tonsillectomy happens to be the commonly performed surgery these days. Like any other surgical procedure this surgical procedure has also undergone tremendous technological changes. One such evolving change happens to be coblation tonsillectomy. Coblation technology is actually an offshoot of radiofrequency surgery. This technique involves passing radiofrequency energy through a conductive medium like isotonic sodium chloride or potassium chloride solution. This produces a plasma field which is composed of sodium and hydroxyl ions which ablates tissue. This tissue ablation takes place at (60-70° C which is much lower than that achieved during other electro surgical techniques (400 – 600° C. This article attempts to discuss the use of this technology to perform tonsillectomy with special emphasis on sharing our experience with the system. This study involves critical appraisal of 25 coblation tonsillectomy surgeries performed at Stanley Medical college during the year 2013.

    Recent advances in studies of electron-ion recombination processes at low relative energies with the electron cooler of the heavy-ion storage ring CRYRING are shown. Through the use of an adiabatically expanded electron beam, collisions down to 10{sup -4}eV relative energies were measured with highly charged ions stored in the ring at around 15 MeV/amu energies. Examples of recombination measurements for bare ions of D{sup +}, He{sup 2+}, N{sup 7+}, Ne{sup 10+} and Si{sup 14+} are presented. Further on, results of an experiment measuring laser-induced recombination (LIR) into n=3 states of deuterium with polarized laser light are shown.

    Hay, D

    2001-01-01

    Flammable gases are often used in detectors for physics experiments. The storage, distribution and manipulation of such flammable gases present several safety hazards. As most flammable gases cannot be detected by human senses, specific well-placed gas detection systems must be installed. Following a request from the user group and in collaboration with CERN safety officers, risk analyses are performed. An external contractor, who needs to receive detailed user requirements from CERN, performs the installations. The contract is passed on a guaranteed results basis. Co-ordination between all the CERN groups and verification of the technical installation is done by ST/AA/AS. This paper describes and focuses on the structured methodology applied to implement such installations based on goal directed project management techniques (GDPM). This useful supervision tool suited to small to medium sized projects facilitates the task of co-ordinating numerous activities to achieve a completely functional system.

    This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

    1987-01-01

    Tribology, the study of friction and wear of materials, has achieved a new interest because of the need for energy conservation. Fundamental understanding of this field is very complex and requires a knowledge of solid-state physics, material science, chemistry, and mechanical engineering. This paper is meant to be didactic in nature and outlines some of the considerations needed for a tribology research program. The approach is first to present a simple model, a field emission tip in contact with a flat surface, in order to elucidate important considerations, such as contact area, mechanical deformations, and interfacial bonding. Then examples from illustrative experiments are presented. Finally, the current status of physical theories concerning interfacial bonding are presented.

  6. INITIAL COOLING EXPERIMENT (ICE)

    CERN Multimedia

    1979-01-01

    ICE was built in 1977, using the modified bending magnets of the g-2 muon storage ring (see 7405430). Its purpose was to verify the validity of stochastic and electron cooling for the antiproton project. Stochastic cooling proved a resounding success early in 1978 and the antiproton project could go ahead, now entirely based on stochastic cooling. Electron cooling was experimented with in 1979. The 26 kV equipment is housed in the cage to the left of the picture, adjacent to the "e-cooler" located in a straight section of the ring. With some modifications, the cooler was later transplanted into LEAR (Low Energy Antiproton Ring) and then, with further modifications, into the AD (Antiproton Decelerator), where it cools antiprotons to this day (2006).

    The Cibola Flight Experiment (CFE) is an experimental small satellite carrying a reconfigurable processing instrument developed at the Los Alamos National Laboratory that demonstrates the feasibility of using FPGA-based high-performance computing for sensor processing in the space environment. The CFE satellite was launched on March 8, 2007 in low-earth orbit and has operated extremely well since its deployment. The nine Xilinx Virtex FPGAs used in the payload have been used for several high-throughput sensor processing applications and for single-event upset (SEU) monitoring and mitigation. This paper will describe the CFE system and summarize its operational results. In addition, this paper will describe the results from several SEU detection circuits that were performed on the spacecraft.

    Full Text Available The aim of this paper is to describe the experience of careeroriented activities carried out with students of schools in developed and developing countries. Career Guidance in Russia, despite the vast experience of its implementation, is experiencing serious difficulties. In this regard, it is important to take into account the international experience career-oriented activities, such as in the developed countries of North America and the European Union as well as in several Asian countries with rapidly growing economies and a large demographic potential, taking into account the best variants for the Russian education system. Methods. The experience of career-oriented work undertaken with pupils of the USA, Canada, Israel, France, UK, Germany, Denmark, Sweden, Japan, Singapore, China and India is shown on the basis of the comparative analysis of different publications and information sources. The author has made an attempt to generalize the principles of psycho-pedagogical and administrative assistance in professional self-determination of senior pupils abroad. Scientific novelty. The approaches to career-oriented activities in countries with different levels of economic development are compared for the first time. Some principles are revealed. Firstly, the higher the income level per capita in the country, the greater attention is given to vocational guidance. The politics in the developed countries is based on interests of the individual: children’s acquaintance with the world of professions begins already at younger school and the moment of definitive selfdetermination is postponed till the end of their senior stage of education; the possibility of direction change of professional preparation in case of detection of discrepancy of qualities of the pupil to originally selected profile is provided. Career-oriented activity in developing countries, on the contrary, is rigidly coordinated to requirements of economy and a labour market

  10. The Bumpy Torus Experiment

    2016-06-09

    This document summarizes the Bumpy Torus Experiment as a viable fusion reactor concept. Conclusions reached include the following: In 30 years, order-of-magnitude technological advances have occurred in multiple areas of plasma heating and confinement. The ORNL bumpy torus of the 1970s was technology limited. Now that ITER is technology limited, an alternate concept is needed. A device built on such a concept should be current free, CW, modular, have a gentle shutdown, and demonstrable stability. The bumpy torus meets or has the potential to meet all of these criteria. Earlier, stability was not possible due to power limits; it has not been fully tested. It is time to revisit the bumpy-torus concept with a modest new machine.

    When a high-voltage direct-current is applied to two beakers filled with water or polar liquid dielectrica, a horizontal bridge forms between the two beakers. This experiment was first carried out by Lord Armstrong in 1893 and then forgotten until recently. Such bridges are stable by the action of electrohydrodynamic (EHD) forces caused by electric field gradients counteracting gravity. Due to these gradients a permanent pumping of liquid from one beaker into the other is observed. At macroscopic scale several of the properties of a horizontal water bridge can be explained by modern electrohydrodynamics, analyzing the motion of fluids in electric fields. Whereas on the molecular scale water can be described by quantum mechanics, there is a conceptual gap at mesoscopic scale which is bridged by a number of theories including quantum mechanical entanglement and coherent structures in water - theories that we discuss here. Much of the phenomenon is already understood, but even more can still be learned from it, since such "floating" liquid bridges resemble a small high voltage laboratory of their own: The physics of liquids in electric fields of some kV/cm can be studied, even long time experiments like neutron or light scattering are feasible since the bridge is in a steady-state equilibrium and can be kept stable for hours. It is also an electro-chemical reactor where compounds are transported through by the EHD flow, enabling the study of electrochemical reactions under potentials which are otherwise not easily accessible. Last but not least the bridge provides the experimental biologist with the opportunity to expose living organisms such as bacteria to electric fields without killing them, but with a significant influence on their behavior, and possibly, even on their genome.

    The overall objective of this experiment is exploratory reconnaissance of Jupiter, Saturn, their satellites, and Saturn's rings. Such reconnaissance, at resolutions and phase angles unobtainable from Earth, can be expected to provide much new data relevant to the atmospheric and/or surface properties of these bodies. The experiment also has the following specific objectives: Observe and characterize the global circulation of the atmospheres of Jupiter and Saturn; Determine the horizontal and vertical structure of the visible clouds and establish their relationship to the belted appearance and dynamical properties of the planetary atmospheres; Determine the vertical structure of high, optically-thin, scattering layers on Jupiter and Saturn; Determine the nature of anomalous features such as the Great Red Spot, South Equatorial Belt disturbances, etc.; Characterize the nature of the colored material in the clouds of Jupiter and Saturn, and identify the nature and sources of chromophores on Io and Titan; Perform comparative geologic studies of many satellites at less than 15-km resolution; Map and characterize the geologic structure of several satellites at high resolution (???1 km); Investigate the existence and nature of atmospheres on the satellites; Determine the mass, size, and shape of many of the satellites by direct measurement; Determine the direction of the spin axes and periods of rotation of several satellites, and establish coordinate systems for the larger satellites; Map the radial distribution of material in Saturn's rings at high resolution; Determine the optical scattering properties of the primaries, rings, and satellites at several wavelengths and phase angles; Search for novel physical phenomena, e.g., phenomena associated with the Io flux tube, meteors, aurorae, lightning, or satellite shadows. ?? 1977 D.

  16. Examining Changes in Radioxenon Isotope Activity Ratios during Subsurface Transport

    Annewandter, Robert

    2014-05-01

    The Non-Proliferation Experiment (NPE) has demonstrated and modelled the usefulness of barometric pumping induced gas transport and subsequent soil gas sampling during On-Site inspections. Generally, gas transport has been widely studied with different numerical codes. However, gas transport of radioxenons and radioiodines in the post-detonation regime and their possible fractionation is still neglected in the open peer-reviewed literature. Atmospheric concentrations of the radioxenons Xe-135, Xe-133m, Xe-133 and Xe-131m can be used to discriminate between civilian releases (nuclear power plants or medical isotope facilities), and nuclear explosion sources. It is based on the multiple isotopic activity ratio method. Yet it is not clear whether subsurface migration of the radionuclides, with eventual release into the atmosphere, can affect the activity ratios due to fractionation. Fractionation can be caused by different mass diffusivities due to mass differences between the radionuclides. Cyclical changes in atmospheric pressure can drive subsurface gas transport. This barometric pumping phenomenon causes an oscillatoric flow in upward trending fractures or highly conductive faults which, combined with diffusion into the porous matrix, leads to a net transport of gaseous components - a so-called ratcheting effect. We use a general purpose reservoir simulator (Complex System Modelling Platform, CSMP++) which is recognized by the oil industry as leading in Discrete Fracture-Matrix (DFM) simulations. It has been applied in a range of fields such as deep geothermal systems, three-phase black oil simulations, fracture propagation in fractured, porous media, and Navier-Stokes pore-scale modelling among others. It is specifically designed to account for structurally complex geologic situation of fractured, porous media. Parabolic differential equations are solved by a continuous Galerkin finite-element method, hyperbolic differential equations by a complementary finite

    López-Caniego, Marcos

    The QUIJOTE (Q-U-I JOint Tenerife) Experiment† (Rubiño-Martín et al. 2010)) is observing the polarization of the Cosmic Microwave Background and other Galactic and extragalactic signals at medium and large angular scales in the frequency range of 10-40 GHz. This experiment is going to provide valuable information about the polarization properties of synchrotron and anomalous microwave emission at these frequencies. It consists of two telescopes and three instruments located at the the Teide Observatory (2400 m) in Tenerife, Canary Islands, Spain. This project has two phases: Phase I, the first telescope (QT1) and a multi-frequency instrument (MFI) are in operations since November 2012 observing between 10 and 20 GHz. A second instrument (TGI) with 31 polarimeters working at 30 GHz is expected to start operations in Autumn 2015 and will be devoted to primordial B-mode science. This instrument will include a fixed polariser and 90 and 180 phase switches to generate four polarization states to minimize the different systematics in the receiver; Phase II, a second QUIJOTE telescope (QT2), already in operation, and a third instrument (FGI) with 40 polarimeters working at 41 GHz, safely below the 60-GHz oxygen absorption band, will significantly increment the sensitivity of the QUIJOTE project to detect the r parameter (tensor-to-scalar ratio). The reason for this is not only the significant reduction of noise due to the number of polarimeters that will incorporate but also the lower synchrotron signal from our galaxy expected at these higher frequencies. The maps obtained with the multi-frequency instrument (10-20 GHz), in combination with data from other experiments like Planck and the VLA, will be used to clean the diffuse and compact foreground emission at 30 and 40 GHz, the cosmological channels. After three years of effective observations we expect to reach the required sensitivity to detect a primordial gravitational-wave component if the tensor

    The Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), USA has provided scientific data management support for the US Department of Energy and international climate change science since 1982. Among the many data activities CDIAC performs are design and implementation of the data systems. One current example is the data system and network for SPRUCE experiment. The SPRUCE experiment (http://mnspruce.ornl.gov) is the primary component of the Terrestrial Ecosystem Science Scientific Focus Area of ORNL's Climate Change Program, focused on terrestrial ecosystems and the mechanisms that underlie their responses to climatic change. The experimental work is to be conducted in a bog forest in northern Minnesota, 40 km north of Grand Rapids, in the USDA Forest Service Marcell Experimental Forest (MEF). The site is located at the southern margin of the boreal peatland forest. Experimental work in the 8.1-ha S1 bog will be a climate change manipulation focusing on the combined responses to multiple levels of warming at ambient or elevated CO2 (eCO2) levels. The experiment provides a platform for testing mechanisms controlling the vulnerability of organisms, biogeochemical processes and ecosystems to climatic change (e.g., thresholds for organism decline or mortality, limitations to regeneration, biogeochemical limitations to productivity, the cycling and release of CO2 and CH4 to the atmosphere). The manipulation will evaluate the response of the existing biological communities to a range of warming levels from ambient to +9°C, provided via large, modified open-top chambers. The ambient and +9°C warming treatments will also be conducted at eCO2 (in the range of 800 to 900 ppm). Both direct and indirect effects of these experimental perturbations will be analyzed to develop and refine models needed for full Earth system analyses. SPRUCE provides wide range continuous and discrete measurements. To successfully manage SPRUCE data flow

    2010-01-01

    Full Text Available In contemporary aesthetics exists an belief, that the experience of art is the primary fact, which initiates and leads theoretical reflection, as also is the state basis of creating, valuing and the opinion on art. Present text is the test of philosophical recognition of relationship between field of products of new art as well as with context formative it experiences. Author motivates thesis, that radical changes in present art have their source in of meanings consisting on primary notion of experience changes. The present artistic practice goes away from aesthetical experience as empiria and the contemplation and used the notion of experience as experiment and investigation, which dismisses art from her proper functions and brings it rather to aggressive ideology of scientism. The recognition of this progressive change of meanings in founding the art notion of experience has the important consequences both for understanding of present art and for describing it theory.

    Nepal's panchayat system of partyless democracy with 5 class organizations of peasants, youth, women, labor, and ex-servicemen, is an effort in community development. Panchayat training centers train panchayat secretaries and women workers. The government tried out the Mobile Training Scheme (MTS) methodology to train panchayat training center instructors in 1974-75 when 5 courses were given for 76 participants. The MTS methodology included several new assumptions: the necessity of knowing the field situation, a realistic problem solving orientation, learning by actual field experience, and interdependence rather than teacher dependence. The multipurpose role of the panchayat secretary was studied and clarified. Role performance led to the development of a realistic job description from which a task-focused curriculum could be developed. Field work tools included maintaining a daily diary, collecting information and developing a present and past project history, and compiling a village profile. The trainees played the roles of front line workers in the field when they returned from the villages played the roles of supervisors and trainers. The key concept in the multipurpose role of the panchayat secretary was collaboration. The panchayat secretary-trainee had to understand the social roles in the community, and work within the social context to get cooperation from other agencies, village and informal organizations, in order to fulfill their role. Tutorial and team teaching methods were used to provide partnership in learning; the old roles of lecturer and lectured were seen as ineffective when actual field experience was the criteria. The role performing and role analysis group analyzed the front line workers' roles and evolved job descriptions which led to course outlines. The teaching methods and materials group produced indigenous teaching materials for classroom use based on problems faced in the field. The action research and technical collaboration groups

    Full Text Available The article presents the experience of the Institute of Socio-Economic Development of Territories of RAS in conducting sociological research on the territory of the Vologda Oblast and the Northwestern Federal District. It describes the historical aspects of formation of the system for public opinion monitoring and examines its theoretical and methodological foundations. The author of the article analyzes the structure of monitoring indicators and provides a brief interpretation of research findings that reflect social wellbeing and social perception trends. In addition, the paper analyzes people’s attitude toward the activities of federal and regional authorities, trends in social well-being, consumer sentiment and also the complex indicator – the index of public sentiment in the region – developed by ISEDT RAS researchers. The results of sociological studies carried out at ISEDT RAS correlate with the dynamics of the all-Russian public opinion polls conducted by the Institute of Sociology of the Russian Academy of Sciences, the Russian Public Opinion Research Center (VCIOM, Levada-Center, etc. They indicate that Russian society gradually adapts to new conditions of life after the collapse of the USSR. Besides, opinion polls show the most important features of the post-Soviet Russian history at its present stage; they are associated with the intensification of international political relations, the consequences of the “Crimean spring” and the new challenges Russia’s economy is facing now. The article concludes that as global community, of which Russian society is part, is evolving, sociological knowledge begins to play an increasingly important role in administration and national security; this is associated with the greater importance attached to intangible development factors. Therefore, a necessary prerequisite for administration effectiveness in all its stages is to implement the results of sociological research on social

    1998-12-31

    This presentation discusses the technology and experience of Petrobras in the development of deep-water exploitation off the coast of Brazil. The company recently found important oil deposits in waters over 300 m deep in Campos Basin, the main petroleum province in Brazil, located offshore Rio de Janeiro State. It is estimated that 50% of the new discoveries will take place in waters deeper than 1000 m. Unlike other companies, Petrobras made an option to develop its offshore fields by means of sub-sea equipment and floating production units. This was possible mainly because of the characteristics of the reservoirs and the mild environmental conditions in Campos Basin. Petrobras has 288 subsea trees on the seabed, 48 subsea manifolds and 21 floating production units in operation. The company has constantly moved on to deeper and deeper waters and by the end of 1998 a new milestone will be achieved with a Roncador field subsea well at 1853 m. Procap-2000, a strategic research and development corporate programme for ultra-deep water technology, was developed. Other innovations by Petrobras are also discussed. 3 figs.

    Full Text Available Lepton Flavour Violation in the charged lepton sector (CLFV is forbidden in the Minimal Standard model and strongly suppressed in extensions of the model to include finite neutrino mixing. On the other hand, a wide class of Supersymmetric theories, even coupled with Grand Unification models (SUSY-GUT models, predict CLFV processes at a rate within the reach of new experimental searches operated with high resolution detectors at high intensity accelerators. As the Standard model background is negligible, the observation of one or more CLFV events would provide incontrovertible evidence for physics beyond Standard model, while a null effect would severely constrain the set of theory parameters. Therefore, a big experimental effort is currently (and will be for incoming years accomplished to achieve unprecedented sensitivity on several CLFV processes. In this paper we review past and recent results in this research field, with focus on CLFV channels involving muons and tau's. We present currently operating experiments as well as future projects, with emphasis laid on how sensitivity enhancements are accompanied by improvements on detection techniques. Limitations due to systematic effects are also discussed in detail together with the solutions being adopted to overcome them.

    Full Text Available It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote laboratories have tackled this issues providing online reusable and shared workbenches unconstrained by neither geographical nor time considerations. Thereby, they have extremely proliferated among universities and integrated into engineering curricula over the last decade. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR, on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well. In addition, the paper address the next challenges and future works carried out at several universities within the VISIR community.

    To explore the experience and value of overlay tympanoplasty. Sixty-three ears with overlay tympanoplasty were reviewed and followed up for the external auditory canal, tympanic membrane and hearing. The diseases of the patients included middle ear cholesteatoma in 25 ears and chronic suppurative otitis media in 38 ears. The surgical techniques involved three kinds: overlay tympanoplasty, overlay tympanoplasty with canal wall up mastoidectomy and overlay tympanoplasty with canal wall down mastoidectomy. In middle ear cholesteatoma and suppurative otitis media patients, the case received the three techniques are 4, 17, 4 ears and 19, 18, 1 ears respectively. All patients gained stage I incision cure. Followed up for 0.5 to 3.5 years respectively, the external auditory canal was wide and tympanic membrane gained a good shape. The hearing in all case kept intact or increased while hearing decrease did not occur. Complications were free in patients with punctual visit. Overlay tympanoplasty has positive significance in treating the chronic otitis media with the merits of standard procedure, sufficient operative field and thorough erosion elimination.

    1998-11-01

    We seek a better understanding of the atomization of paints for purposes of limiting the environmental impact of spray painting. However, to do so one must confront both the shear and extensional rheology of mobile non-Newtonian fluids whose very composition is often complex and even unknown. A conventional Couette rheometer yields data on paint shear behavior, but no commercial instrument is available to measure the extensional viscosity, which is believed to govern ligamentary breakup in spray painting. Here a converging-flow extensional rheometer has been built for this purpose. Flow rate and orifice pressure drop are measured and related to the rheological properties of the fluid. At first, experience was gained by visualizing in this device the flow of clear aqueous solutions of both Newtonian (glycerol) and non-Newtonian (polyacrylamide) thickeners. Commercial latex and marine paints were then tested, with the goal of characterizing their extensional behavior and the hope that they might be replaceable by simpler aqueous rheological "substitute" fluids insofar as their atomization behavior is concerned.

    Cosmic ray particles hit the Earth's atmosphere and induce extensive air showers (EAS). These EAS mainly consist of electrons and positrons that produce radio emission due to their interaction with the Earth's magnetic field. Measuring this radio emission is the purpose of the LOPES (LOFAR Prototype Station) experiment. LOPES is located at Campus North of the Karlsruhe Institute of Technology at the same site as the EAS particle detector KASCADE-Grande. Since the first measurements in 2003, LOPES was improved by various experimental setups and could establish the radio technique. By now, detailed studies of the measured radio signal are performed, like the behaviour of the lateral distribution or the polarization of the electric field. Furthermore, with LOPES the dependence of the radio pulse on properties of the incoming cosmic ray, like primary energy, primary mass, or incoming direction is investigated. In this article we describe the different LOPES setups, next we explain our standard analysis procedure and then we discuss some highlights of our recent results.

  16. Single-nucleon experiments

    Energy Technology Data Exchange (ETDEWEB)

    Deur, Alexandre

    2009-12-01

    We discuss the Jefferson Lab low momentum transfer data on moments of the nucleon spin structure functions $g_1$ and $g_2$ and on single charged pion electroproduction off polarized proton and polarized neutron. A wealth of data is now available, while more is being analyzed or expected to be taken in the upcoming years. Given the low momentum transfer selected by the experiments, these data can be compared to calculations from Chiral Perturbation theory, the effective theory of strong force that should describe it at low momentum transfer. The data on various moments and the respective calculations do not consistently agree. In particular, experimental data for higher moments disagree with the calculations.The absence of contribution from the $\\Delta$ resonance in the various observables was expected to facilitate the calculations and hence make the theory predictions either more robust or valid over a larger $Q^2$ range. Such expectation is verified only for the Bjorken sum, but not for other observables in which the $\\Delta$ is suppressed. Preliminary results on pion electroproduction off polarized nucleons are also presented and compared to phenomenological models for which contributions from different resonances are varied. Chiral Perturbation calculations of these observables, while not yet available, would be valuable and, together with these data, would provide an extensive test of the effective theory.

  17. Gathering positive experience

    2009-01-01

    Last Monday, the new CERN Machine Advisory Committee (CMAC) met for the first time, and we had good news to tell its members. Over the weekend, injection tests for both LHC beams were successfully carried out. In other words, we’ve had beam in the LHC for the first time since September 2008. That’s a good feeling, but it’s no reason for complacency. There’s still a long way to go before first physics at the new energy frontier. As the Bulletin has reported over recent weeks, we’re gathering a lot of positive experience with the new quench detection and protection system (QPS), which is already allowing us to monitor the LHC far better than we were able to in the past. So far, the QPS for three of the LHC’s eight sectors has been put through its paces, and we’ve also power tested those sectors to 2000 amperes, the equivalent of around 1.2 TeV per beam. The next step is to slowly increase the current to 4000 amperes, and...

  18. My experience in arbitration

    2011-12-01

    Full Text Available This paper deals with the nature of arbitration as one of the alternatives in dispute resolution processes different from mediation and conciliation, and obviously, from judicial adjudication. Unlike a mediator or a conciliator, an arbitrator is empowered to pass a judgement, like a court. In other words, the arbitrator will render a decision which is binding for the parties. The arbitrator has the jurisdictio, like a judge. Although the office of a judge and an arbitrator is the same, the source of their power is different. The judge’s power originates from a State, whereas the power of the arbitrator results primarily from a contract. Unlike the court, the arbitrator lacks the imperium, i.e. the power to make the award enforceable. When a party refuses to enforce the award, enforceability can only be provided by the judge or an authority of the state where the award has to be enforced. In a certain sense the state thus provides the back up for the arbitration system. This paper presents personal thoughts drawn from the author’s professional experience as an arbitrator in Franco-German disputes.

    Overall, the worldwide experience on enalapril to date is very encouraging. The drug produces good to excellent responses in 54 to 66 percent of patients with essential hypertension and is at least as effective as either diuretics or beta blockers. The effects of enalapril compared with those of diuretics confirm that patients more dependent upon the renin-angiotensin system respond better. When hydrochlorothiazide is administered concomitantly with enalapril, almost all patients respond, with good long-term maintenance. In patients with severe hypertension, Blocadren or Aldomet may be added in addition to hydrochlorothiazide and will produce additional benefit. Enalapril attenuates the adverse metabolic effects of hydrochlorothiazide, particularly hypokalemia. Overall, although the efficacy of enalapril and that of captopril are similar, enalapril is better tolerated and does not appear to be associated with any significant occurrence of captopril-type side effects, particularly the skin rash and loss of taste. As expected, enalapril and other converting inhibitors may be associated with azotemia in patients with bilateral renovascular hypertension.

    Up to now, the experiments carried out throughout the world with enalapril have been most encouraging. The drug gives good, even excellent responses in 54 to 66 % of patients with essential hypertension, and it is at least as effective as diuretics and beta-blockers. Compared with those of diuretics, the effects of enalapril confirm that the best responders are those patients who are most dependent on the renin-angiotensin system. When a diuretic is administered concomitantly with enalapril, almost all patients respond and the therapeutic effect is well maintained in long term. Blocadren or alpha-methyldopa can be added to hydrochlorothiazide, thus providing additional benefits to patients with severe hypertension. Enalapril reduces the undesirable metabolic effects of hydrochlorothiazide, particularly hypokalaemia. Altogether, enalapril and captopril have similar effectiveness, but enalapril is better tolerated and does not seem to produce the side-effects encountered with captopril, notably skin rashes and ageusia. As expected, enalapril and other angiotensin-converting enzyme inhibitors may be associated with azotaemia in patients with bilateral renovascular hypertension.

    Full Text Available RationaleParalysed human volunteers (n=6 participated in an electroencephalographic study after which they undertook studies of attempted eye movement. The interventions tested a central, intentional component to one’s internal visual model.Methods Six subjects reclined in a supported chair and were ventilated after paralysis (cisatracurium, 20 mg intravenously. In illumination, subjects were requested to focus alternately on the faces of investigators standing on the left and the right within peripheral vision. In darkness, subjects were instructed to look away from a point source of light. Subjects were to report their experiences after reversal of paralysis.Results During attempted eye movement in illumination, one subject had an illusion of environmental movement but four subjects perceived faces as clearly as if they were in central vision. In darkness, four subjects reported movement of the target light in the direction of attempted eye movements and three could control the movement of the light at will. ConclusionThe hypothesis that internal visual models receive intended ocular-movement-information directly from oculomotor centres is strengthened by this evidence.

    Use of unmanned systems is rapidly growing within the military and civilian sectors in a variety of roles including reconnaissance, surveillance, explosive ordinance disposal (EOD), and force-protection and perimeter security. As utilization of these systems grows at an ever increasing rate, the need for unmanned systems teaming and inter-system collaboration becomes apparent. Collaboration provides a means of enhancing individual system capabilities through relevant data exchange that contributes to cooperative behaviors between systems and enables new capabilities not possible if the systems operate independently. A collaborative networked approach to development holds the promise of adding mission capability while simultaneously reducing the workload of system operators. The Joint Collaborative Technology Experiment (JCTE) joins individual technology development efforts within the Air Force, Navy, and Army to demonstrate the potential benefits of interoperable multiple system collaboration in a force-protection application. JCTE participants are the Air Force Research Laboratory, Materials and Manufacturing Directorate, Airbase Technologies Division, Force Protection Branch (AFRL/RXQF); the Army Aviation and Missile Research, Development, and Engineering Center Software Engineering Directorate (AMRDEC SED); and the Space and Naval Warfare Systems Center - Pacific (SSC Pacific) Unmanned Systems Branch operating with funding provided by the Joint Ground Robotics Enterprise (JGRE). This paper will describe the efforts to date in system development by the three partner organizations, development of collaborative behaviors and experimentation in the force-protection application, results and lessons learned at a technical demonstration, simulation results, and a path forward for future work.

    The discovery of neutrino oscillations marks a major milestone in the history of neutrino physics, and opens a new window to the still mysterious origin of masses and flavour mixing. Many current and forthcoming experiments will answer open questions; however, a major step forward, up to and possibly including CP violation in the neutrino-mixing matrix, requires the neutrino beams from a neutrino factory. The neutrino factory is a new concept for producing neutrino beams of unprecedented quality in terms of intensity, flavour composition, and precision of the beam parameters. Most importantly, the neutrino factory is the only known way to generate a high-intensity beam of electron neutrinos of high energy. The neutrino beam from a neutrino factory, in particular the electron-neutrino beam, enables the exploration of otherwise inaccessible domains in neutrino oscillation physics by exploiting baselines of planetary dimensions. Suitable detectors pose formidable challenges but seem within reach with only moderate extrapolations from existing technologies. Although the main physics attraction of the neutrino factory is in the area of neutrino oscillations, an interesting spectrum of further opportunities ranging from high-precision, high-rate neutrino scattering to physics with high-intensity stopped muons comes with it.

    The objective of the Nordic Snow Radar Experiment (NoSREx) campaign was to provide a continuous time series of active and passive microwave observations of snow cover at a representative location of the Arctic boreal forest area, covering a whole winter season. The activity was a part of Phase A studies for the ESA Earth Explorer 7 candidate mission CoReH2O (Cold Regions Hydrology High-resolution Observatory). The NoSREx campaign, conducted at the Finnish Meteorological Institute Arctic Research Centre (FMI-ARC) in Sodankylä, Finland, hosted a frequency scanning scatterometer operating at frequencies from X- to Ku-band. The radar observations were complemented by a microwave dual-polarization radiometer system operating from X- to W-bands. In situ measurements consisted of manual snow pit measurements at the main test site as well as extensive automated measurements on snow, ground and meteorological parameters. This study provides a summary of the obtained data, detailing measurement protocols for each microwave instrument and in situ reference data. A first analysis of the microwave signatures against snow parameters is given, also comparing observed radar backscattering and microwave emission to predictions of an active/passive forward model. All data, including the raw data observations, are available for research purposes through the European Space Agency and the Finnish Meteorological Institute. A consolidated dataset of observations, comprising the key microwave and in situ observations, is provided through the ESA campaign data portal to enable easy access to the data.

    Full Text Available The LHCf experiment has taken data in 2009 and 2010 p-p collisions at LHC at √s = 0.9 TeV and √s = 7 TeV. The measurement of the forward neutral particle spectra produced in proton-proton collisions at LHC up to an energy of 14 TeV in the center of mass system are of fundamental importance to calibrate the Monte Carlo models widely used in the high energy cosmic ray (HECR field, up to an equivalent laboratory energy of the order of 1017 eV. In this paper the first results on the inclusive photon spectrum measured by LHCf is reported. Comparison of this spectrum with the model expectations show significant discrepancies, mainly in the high energy region. In addition, perspectives for future analyses as well as the program for the next data taking period, in particular the possibility to take data in p-Pb collisions, will be discussed.

    The Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrinos (CAPTAIN) program is designed to make measurements of scientific importance to long-baseline neutrino physics and physics topics that will be explored by large underground detectors. The experiment employs two liquid Argon time projection chambers (LArTPCs), a primary detector with a mass of approximately 10 ton that will be deployed at different facilities for physics measurements and a two ton prototype detector for configuration testing. The physics programs for CAPTAIN include measuring neutron interactions at the Los Alamos Neutron Science Center, measuring neutrino interactions in the high-energy regime (1.5-5 GeV) at Fermilab NuMI beam, and measuring neutrino interactions in the low-energy regime (<50 MeV) at stopped pion sources for supernova neutrino studies. The prototype detector (Mini-CAPTAIN) has been commissioned and the first UV laser track has been seen in its TPC. This paper gives an overview of the CAPTAIN pr...

    In order to conduct the shield design calculation of the Large Hadron Collider (LHC) under planning in CERN at present, the radiation group of CERN uses FLUKA (Monte Carlo High Energy Radiation Transport Code). Here is introduced on outline of FLUKA and use experience of FLUKA in the LHC-B detector shield design calculation in LHC plan. FLUKA can be said to be the highest standard in the high energy radiation transportation code of the world at every points of the physical model, the Monte Carlo calculation technique and the convenience at usage of the code. In Japan Atomic Energy Research Institute (JAERI), a using right of FLUKA for the target neutronics and facility shielding design at the neutron science research center is obtained and it seems to be an effective design means in these future designs. However, because FLUKA is allowed a limited opening and no own verification on the code, it will be supposed to be a large problem on investigating a validity in design. (K.G.)

    ascination with materials and chemical change is a hallmark of chemists, and it is also an important pedagogical tool. A fringe benefit of editing JCE is that I encounter so many nice people who send interesting and helpful communications. One of the first of these to cross my desk this year was from E. J. Behrman, who recommended that I read and call to your attention "Brilliant Light: A Chemical Boyhood" by Oliver Sacks, noted neurologist and author. It appeared in the December 20, 1999, issue of The New Yorker and is well worth your time and effort to find and read. Sacks's reminiscence of his boyhood interest in chemistry is fascinating. His obvious love of our science is inspiring. And he has expressed both in words that are brilliantly chosen and a joy to read. In a profile of Sacks that appeared in Chemical and Engineering News (January 10, 2000), Madeleine Jacobs relates that he is writing a book on his boyhood encounters with chemistry (to be published by Alfred A. Knopf). I am looking forward to that with great anticipation. During 1999 he also wrote an article on the periodic table in the New York Times Magazine (April 18) and an op-ed piece on chemistry sets in the New York Times (May 13). In the latter he describes how hard it is these days for a nonchemist, especially a young one, to obtain chemicals to experiment with. Chemistry sets are not what they used to be! Sacks's writings contain important messages for all of us who teach chemistry and all who are involved in piquing students' interest in our subject. A brief excerpt from his New Yorker article illustrates my point. I knew zinc--the dull, slightly bluish birdbath in the garden was made of zinc--and tin, from the heavy tinfoil in which sandwiches were wrapped for a picnic. My mother showed me that when tin or zinc was bent it uttered a special "cry." "It's due to deformation of the crystal structure," she said, forgetting that I was five and could not understand her--and yet her words made me

    1998-01-01

    First there was agriculture, then manufactured goods, and eventually services. Each change represented a step up in economic value--a way for producers to distinguish their products from increasingly undifferentiated competitive offerings. Now, as services are in their turn becoming commoditized, companies are looking for the next higher value in an economic offering. Leading-edge companies are finding that it lies in staging experiences. To reach this higher level of competition, companies will have to learn how to design, sell, and deliver experiences that customers will readily pay for. An experience occurs when a company uses services as the stage--and goods as props--for engaging individuals in a way that creates a memorable event. And while experiences have always been at the heart of the entertainment business, any company stages an experience when it engages customers in a personal, memorable way. The lessons of pioneering experience providers, including the Walt Disney Company, can help companies learn how to compete in the experience economy. The authors offer five design principles that drive the creation of memorable experiences. First, create a consistent theme, one that resonates throughout the entire experience. Second, layer the theme with positive cues--for example, easy-to-follow signs. Third, eliminate negative cues, those visual or aural messages that distract or contradict the theme. Fourth, offer memorabilia that commemorate the experience for the user. Finally, engage all five senses--through sights, sounds, and so on--to heighten the experience and thus make it more memorable.

    Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

    The criteria for the selection of the experimental areas and individual experiments were that the experiment or area must make a meaningful contribution to the field of material science and that the space environment was either an absolute requirement for the successful execution of the experiment or that the experiment can be more economically or more conveniently performed in space. A number of experimental areas and individual experiments were recommended for further consideration as space experiments. Areas not considered to be fruitful and others needing additional analysis in order to determine their suitability for conduct in space are also listed. Recommendations were made concerning the manner in which these materials science experiments are carried out and the related studies that should be pursued.

    The Galileo ultraviolet spectrometer experiment uses data obtained by the Ultraviolet Spectrometer (UVS) mounted on the pointed orbiter scan platform and from the Extreme Ultraviolet Spectrometer (EUVS) mounted on the spinning part of the orbiter with the field of view perpendicular to the spin axis. The UVS is a Ebert-Fastie design that covers the range 113-432 nm with a wavelength resolution of 0.7 nm below 190 and 1.3 nm at longer wavelengths. The UVS spatial resolution is 0.4 deg x 0.1 deg for illuminated disk observations and 1 deg x 0.1 deg for limb geometries. The EUVS is a Voyager design objective grating spectrometer, modified to cover the wavelength range from 54 to 128 nm with wavelength resolution 3.5 nm for extended sources and 1.5 nm for point sources and spatial resolution of 0.87 deg x 0.17 deg. The EUVS instrument will follow up on the many Voyager UVS discoveries, particularly the sulfur and oxygen ion emissions in the Io torus and molecular and atomic hydrogen auroral and airglow emissions from Jupiter. The UVS will obtain spectra of emission, absorption, and scattering features in the unexplored, by spacecraft, 170-432 nm wavelength region. The UVS and EUVS instruments will provide a powerful instrument complement to investigate volatile escape and surface composition of the Galilean satellites, the Io plasma torus, micro- and macro-properties of the Jupiter clouds, and the composition structure and evolution of the Jupiter upper atmosphere.

    I have had the opportunity to support the analytical laboratories in chemical analysis of unknown samples, using Optical Microscopy (OM), Polarizing Light Microscopy (PLM), Fourier-Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEMEDS), and X-ray Powder Diffraction (XPD). I have assisted in characterizing fibers pulled from a spacecraft, a white fibrous residue discovered in a jet refueler truck, brown residue from a plant habitat slated for delivery to the ISS (International Space Station), corrosion on a pipe from a sprinkler, and air filtration material brought back from the ISS. I also conducted my own fiber study in order to practice techniques and further my understanding of background concepts. Furthermore, I had the opportunity to participate in diverse work assignments, where I was assigned to work with other branches of the engineering department for 1-2 days each. The first was in the Materials Science branch where I participated in the construction of the plant habitat intended for use in research aboard the ISS. The second was in the Testing Design branch where I assisted with tensile and hardness testing of over 40 samples. In addition, I have had the privilege to attend multiple tours of the NASA KSC campus, including to the Astronaut Crew Quarters, the VAB (the main area, the Columbia room, and the catwalk), the Visitor Center housing the shuttle Atlantis, the Saturn-V exhibit, the Prototype laboratory, SWAMP WORKS, the Shuttle Landing Facility, the Crawler, and the Booster Fabrication Facility (BFF). Lastly, much of my coursework prepared me for this experience, including numerous laboratory courses with topics diverse as chemistry, physics, and biology.

    1988-03-01

    A sensor calibration experiment was proposed as part of SIR-B experiments in Japan, together with the rice crop experiment and the ocean oil-pollution detection experiment. This sensor calibration experiment was intended (1) to establish a transfer function from image data to radar backscattering characteristics, (2) to evaluate 3-dB resolutions, (3) to verify the ability to resolve two closely-spaced targets, and (4) to clarify sidelobe structures due to range and azimuth compressions. The disused Akita Airport was chosen as the main test site for the calibration experiment on the first three objectives. This paper describes the test site, the design of the corner reflectors, and briefly predicts the results.

  7. Sleep paralysis as spiritual experience.

    Science.gov (United States)

    Hufford, David J

    2005-03-01

    This article presents an overview of the sleep paralysis experience from both a cultural and a historical perspective. The robust, complex phenomenological pattern that represents the subjective experience of sleep paralysis is documented and illustrated. Examples are given showing that, for a majority of subjects, sleep paralysis is taken to be a kind of spiritual experience. This is, in part, because of the very common perception of a non-physical 'threatening presence' that is part of the event. Examples from various cultures, including mainstream contemporary America which has no widely known tradition about sleep paralysis, are used to show that the complex pattern and spiritual interpretation are not dependent on cultural models or prior learning. This is dramatically contrary to conventional explanations of apparently 'direct' spiritual experiences, explanations that are summed up as the 'Cultural Source Hypothesis.' This aspect of sleep paralysis was not recognized through most of the twentieth century. The article examines the way that conventional modern views of spiritual experience, combined with medical ideas that labeled 'direct' spiritual experiences as psychopathological, and mainstream religious views of such experiences as heretical if not pathological, suppressed the report and discussion of these experiences in modern society. These views have resulted in confusion in the scientific literature on sleep paralysis with regard to its prevalence and core features. The article also places sleep paralysis in the context of other 'direct' spiritual experiences and offers an 'Experiential Theory' of cross-culturally distributed spiritual experiences.

    In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC)[1] experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG[2]/EGEE[3], OSG[4], NDGF[5]) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications.

    A simple, flexible and very low cost hardware plus software framework for developing computer-interfaced science experiments is presented. It can be used for developing computer-interfaced science experiments without getting into the details of electronics or computer programming. For developing experiments this is a middle path between push-button systems and the develop-from-scratch approach. Emphasis is on leveraging the power of personal computers for experiment control, data acquisition and the mathematical analysis of data. The language 'Python' is chosen for data acquisition and analysis. This article explains the architecture of Phoenix (Physics with Home-made Equipment and Innovative Experiments) along with some sample experiments. The hardware design is open and the project is totally based on free software.

    The use of volunteers is becoming more visible and important in the experience economy also in the light of the financial crisis. From a management perspective within both public and private organizations the use of volunteers is an important element partly because they strengthen the brand...... and they help in the product development but also because they are seen as a cheap resource. From an employee perspective you often hear that it creates a sense of fear for cuts or loss of professionalism, but can also be seen as a helpful resource and dynamic element in the organization. In the Experience...... economy volunteers create a new set of dimensions, because they shift between being part of the experience producer and being one of the experience consumers. Volunteers are becoming increasingly more important in the experience economy as they contribute to the overall experience for users or customers...

    Tourism is an experience-intensive sector in which customers seek and pay for experiences above everything else. Remembering past tourism experiences is also crucial for an understanding of the present, including the predicted behaviours of visitors to tourist destinations. We adopt a longitudinal...... approach to memory data collection from psychological science, which has the potential to contribute to our understanding of tourist behaviour. In this study, we examine the impact of remembered tourist experiences in a safari park. In particular, using matched survey data collected longitudinally and PLS...... path modelling, we examine the impact of positive affect tourist experiences on the development of revisit intentions. We find that longer-term remembered experiences have the strongest impact on revisit intentions, more so than predicted or immediate memory after an event. We also find that remembered...

    Young, Joseph G.; Ridzal, Denis

    2013-06-01

    In the following paper, we discuss how to design an ensemble of experiments through the use of compressed sensing. Specifically, we show how to conduct a small number of physical experiments and then use compressed sensing to reconstruct a larger set of data. In order to accomplish this, we organize our results into four sections. We begin by extending the theory of compressed sensing to a finite product of Hilbert spaces. Then, we show how these results apply to experiment design. Next, we develop an efficient reconstruction algorithm that allows us to reconstruct experimental data projected onto a finite element basis. Finally, we verify our approach with two computational experiments.

  16. Heidegger, lived experience and method.

    2014-07-01

    A discussion of the assumption that Heidegger's philosophy in Being And Time provides a warrant for the study of lived experience. It is generally assumed, in nursing as in other disciplines, that Heidegger's philosophy points, uncontroversially, to the study of lived experience. It is also assumed that studies of this type will take the form of qualitative interviews which seek to explore the respondent's experience of a particular phenomenon and to elicit the meanings which the individual concerned attaches to that experience. Being And Time; the philosophical literature on Heidegger since 1999; the literature of experimental social psychology, 1970-2012. According to Heidegger, there is no such thing as 'lived experience'. The concept is embedded in the subject-object dualism that he is attempting to dismantle. In Heideggerian terms, interviews intended to explore 'lived experience' can only reproduce the voice of das Man, the 'They', not the voice of unique individuals. Methods more in keeping with Heidegger's philosophy include observation, naturalistic experiments, some forms of discourse analysis and conceptually associated lines of enquiry involving vocabularies of motive, scripts and the performative aspects of language use. Nursing researchers who wish to embrace Heidegger's philosophy as a basis for their work should abandon 'lived experience' interviews and adopt one of the alternative methods suggested above. Nursing researchers who wish to continue with 'lived experience' interviews should seek an alternative philosophical or theoretical basis for their work. © 2013 John Wiley & Sons Ltd.

  17. Popper's Experiment: A Modern Perspective

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available Karl Popper had proposed an experiment to test the standard interpretation of quantum mechanics. The proposal survived for many year in the midst of no clear consensus on what results it would yield. The experiment was realized by Kim and Shih in 1999, and the apparently surprising result led to lot of debate. We review Popper's proposal and its realization in the light of current era when entanglement has been well studied, both theoretically and experimentally. We show that the "ghost-diffraction" experiment, carried out in a different context, conclusively resolves the controversy surrounding Popper's experiment.Quanta 2012; 1: 19–32.

    Residues of chemicals on clothing products were examined by direct analysis in real-time (DART) mass spectrometry. Our experiments have revealed the presence of more than 40 chemicals in 15 different clothing items. The identification was confirmed by DART tandem mass spectrometry (MS/MS) experiments for 14 compounds. The most commonly detected hazardous substances were nonylphenol ethoxylates (NPEs), phthalic acid esters (phthalates), amines released by azo dyes, and quinoline derivates. DART-MS was able to detect NPEs on the skin of the person wearing the clothing item contaminated by NPE residuals. Automated data acquisition and processing method was developed and tested for the recognition of NPE residues thereby reducing the analysis time.

  20. DHS Research Experience Summary

    Venkatachalam, V

    2008-10-24

    I learned a great deal during my summer internship at Lawrence Livermore National Laboratory (LLNL). I plan to continue a career in research, and I feel that my experience at LLNL has been formative. I was exposed to a new area of research, as part of the Single Particle Aerosol Mass Spectrometry (SPAMS) group, and I had the opportunity to work on projects that I would not have been able to work on anywhere else. The projects both involved the use of a novel mass spectrometer that was developed at LLNL, so I would not have been able to do this research at any other facility. The first project that Zachary and I worked on involved using SPAMS to detect pesticides. The ability to rapidly detect pesticides in a variety of matrices is applicable to many fields including public health, homeland security, and environmental protection. Real-time, or near real-time, detection of potentially harmful or toxic chemical agents can offer significant advantages in the protection of public health from accidental or intentional releases of harmful pesticides, and can help to monitor the environmental effects of controlled releases of pesticides for pest control purposes. The use of organophosphate neurotoxins by terrorists is a possibility that has been described; this is a legitimate threat, considering the ease of access, toxicity, and relatively low cost of these substances. Single Particle Aerosol Mass Spectrometry (SPAMS) has successfully been used to identify a wide array of chemical compounds, including drugs, high explosives, biological materials, and chemical warfare agent simulants. Much of this groundbreaking work was carried out by our group at LLNL. In our work, we had the chance to show that SPAMS fulfills a demonstrated need for a method of carrying out real-time pesticide detection with minimal sample preparation. We did this by using a single particle aerosol mass spectrometer to obtain spectra of five different pesticides. Pesticide samples were chosen to
