    Although it has been a stated policy goal of American and Soviet leaders since 1958 (with the exception of Ronald Reagan), the world today is still without a Comprehensive Test Ban Treaty. Throughout their history, test an negotiatins have been plagued by a number of persistent problems. Chief among these is East-West differences on the verification question, with the United States concerned about the problem of possible Soviet cheating and the USSR concerned about the protection of its national sovereignty. In addition, internal bureaucratic politics have played a major role in preventing the successful conclusion of an agreement. Despite these problems, the superpowers have concluded several significant partial meausres: a brief (1958-1961) total moratorium on nuclear weapons tests; the Limited Test Ban Treaty of 1963, banning tests in the air, water and outer space; the Threshold Test Ban Treaty of 1974 (150 KT limit on underground explosions); and the Peaceful Nuclear Explosions Treaty of 1976 (150 KT limit on individal PNEs). Today, the main U.S. objections to a CTBT center is the nuclear weapons laboratories, the Department of Energy, and the Pentagon, who all stress the issues of stockpile reliability and verification. Those who remain committed to a CTBT emphasize and the potential political leverage it offers in checking both horizontal and vertical proliferation.

  3. The Limited Test Ban Treaty

    Loeb, B.S.

    1991-01-01

    This paper discusses the Limited Test Ban Treaty which came at the end of nearly five years of frustrated efforts to obtain a comprehensive test ban. Negotiations toward that end had begun in October 1958. At the same time a voluntary, informal moratorium on tests was initiated. The negotiations soon stalled over the Soviet Union's resistance to internationally supervised inspections on its soil. In April 1959 a phased ban that was to be limited at first to atmospheric tests conducted below an altitude of 50 kilometers. Such tests were thought to be easily verifiable. The Soviets rejected this idea and continued to insist that a complete test ban need not require numerous inspections. The two sides nevertheless appeared to be nearing agreement on a treaty to ban all but relatively small underground tests when, in May 1960, an U.S. U-2 reconnaissance plane was shot down over Soviet territory. After a thorough review of the U.S. position, the Kennedy administration proposed in April 1961 a draft treaty that made several concessions toward the Soviet position. Nevertheless, the Soviets, still disagreeing with the provisions for verification and with the makeup of the control organization, rejected it

    This report describes verification and its rationale, the basic tasks of seismic verification, the physical basis for earthquake/explosion source discrimination and explosion yield determination, the technical problems pertaining to seismic monitoring of underground nuclear tests, the basic problem-solving strategy deployed by the forensic seismology resarch team at the University of Toronto, and the scientific significance of the team's research. The research carried out at the Univeristy of Toronto has two components: teleseismic verification using P wave recordings from the Yellowknife Seismic Array (YKA), and regional (close-in) verification using high-frequency L g and P n recordings from the Eastern Canada Telemetered Network. Major differences have been found in P was attenuation among the propagation paths connecting the YKA listening post with seven active nuclear explosion testing areas in the world. Significant revisions have been made to previously published P wave attenuation results, leading to more interpretable nuclear explosion source functions. (11 refs., 12 figs.)

    1985-01-01

    The conclusion of a comprehensive nuclear test ban is of critical importance for the future of arms limitation and disarmament. As the 1980 report of the Secretary-General concluded, a comprehensive nuclear test ban is regarded as the first and most urgent step towards the cessation of the nuclear arms race and, in particular, of its qualitative aspects. It could serve as an important measure for the non-proliferation of nuclear weapons, both vertical and horizontal. It would have a major arms limitation impact in that it would make it difficult, if not impossible, to develop new designs of nuclear weapons and would also place constraints on the modification of existing weapon designs. The permanent cessation of all nuclear-weapon tests has long been sought by the world community and its achievement would be an event of great international significance

    In 1986 and again in 1987 the General Assembly adopted resolutions by which it called on States conducting nuclear-test explosions to notify the Secretary-General, within one week of each explosion, of the time, place, yield and site characteristics of the test and also invited all other States to provide any such data on nuclear explosions that they might have. Over the years, in the Conference on Disarmament, members of the Group of 21 (mostly neutral and non-aligned countries) have continued to attach the utmost importance to the urgent conclusion of a comprehensive test-ban treaty as a significant contribution to the aim of ending the qualitative refinement of nuclear weapons and the development of new types of such weapons as well as of reversing the nuclear-arms race and achieving nuclear disarmament. In 1995 a conference will be convened to decide whether the non-proliferation Treaty will continue in force indefinitely, or will be extended for an additional fixed period or periods. Many States support the view that a comprehensive test ban would be a significant contribution to the non-proliferation of nuclear weapons; and some believe that, without a cessation of nuclear testing, it may not be possible to extend the NPT well beyond 1995. Other States, however, are of the opinion that the NPT, independently, offers benefits for the security of all States and, by its extension, will continue to do so

    The author examines why the Comprehensive Nuclear Test Ban (CTB) treaty might not make it through the political minefields. Negotiators at the 60-nation U.N. The conference on Disarmament in Geneva reached an impasse, prompted by India`s assertions that the treaty was an inadequate document that perpetuated {open_quotes}nuclear apartheid{close_quotes} while violating India`s sovereignty. Because the Conference on Disarmament-often called the {open_quotes}Geneva Conference{close_quotes} or the {open_quotes}CD{close_quotes}-operates by consensus, India was able to veto the adoption of the treaty, which the conference had planned to transmit to the United Nations in early September. Australia saved the treaty with a last minute decision to bypass the Geneva Conference and take the CTB directly to the General Assembly in the form of a resolution. Some 127 nations co-sponsored Australia`s resolution, to which the treaty draft was attached. The General Assembly endorsed the treaty by a vote of 158 to three. India, Bhutan, and Libya voted against it. Despite the overwhelming vote, the treaty`s long-range outlook is uncertain. On the day of the vote, India`s chief test-ban negotiator, declared that India would {open_quotes}never sign this unequal treaty because Article XIV of the treaty, which requires that all 44 nuclear-capable nations who also belong to the Conference on Disarmament must sign and ratify the treaty. That requirement was viewed as contrary to international law because it denied India`s right of voluntary consent to an international treaty, thus violating India`s sovereignty.

    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a cornerstone of the international regime on the non-proliferation of nuclear weapons and an essential foundation for the pursuit of nuclear disarmament. Its total ban of any nuclear weapon test explosion will constrain the development and qualitative improvement of nuclear weapons and end the development of advanced new types of these weapons. The Comprehensive Nuclear-Test-Ban Treaty was adopted by the United Nations General Assembly, and was opened for signature in New York on 24 September 1996. The Treaty will enter into force after it has been ratified by the 44 States listed in its Annex 2. These states possess nuclear power or research reactors. The Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO Preparatory Commission) is an international organization established by the States Signatories to the Treaty on 19 November 1996. It carries out the necessary preparations for the effective implementation of the Treaty, and prepares for the first session of the Conference of the States Parties to the Treaty. The Treaty has been signed and ratified by the Republic of Croatia and National Commission for the implementation of the Treaty has been established. Basic obligations of the Treaty, as specified in Article I, are: (1) Each State Party undertakes not to carry out any nuclear weapon test explosion or any other nuclear explosion, and to prohibit and prevent any such nuclear explosion at any place under its jurisdiction or control. (2) Each State Party undertakes, furthermore, to refrain from causing, encouraging, or in any way participating in the carrying out of any nuclear weapon test explosion or any other nuclear explosion.(author)

    1989-01-01

    A survey of international efforts from the partial test-ban Treaty (in atmosphere, in outer space and under water) in 1963 to the Soviet-USA negotiations on verification measures for the threshold test-ban Treaty is given. As was the case in the bilateral and trilateral negotiations, the question of adequate verification procedures has remained one of the major problems in the multilateral considerations on a comprehensive test ban. Over the years, a number of proposals have been made in order to solve the issue, in particular by Sweden and by the Soviet Union. In 1988, the four experimental data centres, situated in Canberra, Moscow, Stockholm and Washington, carried out separate and joint experiments in analysis methodology. Communication techniques between the four international data centres and a number of national seismological stations were also tested. In addition, a global data-gathering experiment was conducted, resulting in the creation of an initial research data base at the experimental data centre in Canberra. Further technical experiments are planned for 1989, an in 1990 a large-scale experiment in data exchange and analysis, involving up to a hundred seismological stations globally and lasting several months, is foreseen

  11. Test ban compliance: is seismology enough

    The treaties under debate were signed more than a decade ago: the Threshold Test Ban Treaty (TTBT) by President Nixon in 1974 and the Peaceful Nuclear Explosions Treaty (PNET) by President Ford in 1976. Between them, they prohibit all underground nuclear blasts with an explosive yield greater than 150 kilotons. When negotiated, verification of the testing agreements was entrusted to seismology, but the remote seismic techniques they must rely on today to monitor Soviet nuclear tests, do not provide yield estimates with the accuracy required for effective verifications of compliance. The alternative seized upon was hydrodynamics. The US technique is called CORRTEX, a mercifully terse acronym for Continuous Reflectometry for Radius versus Time Experiments. A cable connected to a suitcase-sized electrical unit and a microcomputer is buried in a deep satellite hole roughly 50 feet away from the emplacement hole holding the nuclear device. The rate at which the CORRTEX cable is crushed and short-circuited by the shock wave generated by the exploding device provides the yield estimate. The paper compares the accuracy and constraints of both methods, and discusses the Soviet reaction to CORRTEX

    Treaty on limitation of underground nuclear weapon tests and treaty on world banning of nuclear tests contribute to and accompany the process of nuclear disarmament. Test ban in three (Moscow treaty of 1963) as well as the Threshold Test Ban up to 1991 was controlled only with national means. But since 1991 nuclear test threshold of 150 kt has been measured with hydrodynamic and tele seismic methods and checked by the inspection. Distinctive feature of this control is that control is that it is bilateral. This conforms to Treaty on limitation of underground nuclear weapon tests signed by two countries - USA and USSR. The inspection at the place of tests requires monitoring of the test site of the party conducting a test and geological information of rock in the area of explosion. In the treaty of the World Nuclear Test Ban the following ways of international control are provided for: - seismologic measurements; - radionuclide measurements; - hydro-acoustics measurements; - infra-sound measurements; - inspection at the place of the tests conduction

    Dahlman, O.; Israelson, H.

    1980-06-01

    Verification of the compliance with a comprehensive test ban on nuclear explosions is expected to be carried out by a seismological verification system of some fifty globally distributed teleseismic stations designed to monitor underground explosions at large distances (beyond 2000 km). The internal stations, which are intended to operate at much shorter distances, have however also been discussed. Such internal stations would be set up in the USSR and in the US and possibly also in the UK. Estimates partaining to currently used detection techniques (P waves) indicate that a limited number (less than 30) of such stations would not improve significantly upon the detection capability that a global network of stations would have throughout the territories of the US and the USSR. Observations in certain areas in eastern North America indicate that Lg-waves would be more suitable for detection purposes than would P-waves. Internal stations would provide a substantial lowering of detection threshold. Firm conclusions on this point have however to await further studies on Lg-waves. Internal stations would probably provide supplementary identification at short distances. Such data could contribute to more confident identification of seismic events detected by a global network and thereby reduce the risk for misinterpreting earthquakes as clandestine nuclear explosions. According to the estimated detection capabilities in this paper 10 internal stations would not improve significantly upon the detection capability that a global network would have in the US and the USSR. They might however serve an essential political purpose. (author)

    2015-12-01

    In mid-July 2013, New Zealand passed the Psychoactive Substances Act (PSA), which allowed 'low risk' psychoactive products ('legal highs') to be approved for legal sale. In early May 2014, following public protest, the Psychoactive Substances Amendment Act (PSAA) was passed banning animal testing of psychoactive products, potentially making the new regime unworkable. To investigate strategies to overcome the impasse created by the animal testing ban. Solutions to the impasse were investigated using 'scenario' and 'stakeholder' analysis. Legislation, parliamentary debates, and regulatory statements related to the PSA and animal testing were reviewed. Strategies to resolve the impasse were discussed with stakeholders including the Psychoactive Substances Regulatory Authority (PSRA) officials, health officials, a legal high industry lawyer, and a leading legal highs manufacturer. This process generated six possible scenarios and five decision-making criteria of key importance to major stakeholders. Scenarios were then evaluated based on feedback from the industry and regulators. The six scenarios were: (1) pragmatic modification of the animal testing ban; (2) waiting until new non-animal test models are internationally accepted; (3) use of non-validated replacement test methods; (4) judicial challenge of the animal testing ban; (5) 'creative compliance' by only presenting human clinical trial results; and (6) philosophical re-conceptualisation of the 'benefits' from psychoactive products. Options 1 and 5 appear to be the most attractive overall solutions. However, both rely on a new political consensus and astute framing of the issues by political communicators. Political decision makers may be happy to accept Scenario 2 which would impose significant delays. A 'failed' pharmaceutical product with psychoactive effects may have the test data required to be approved under Scenarios 1 and 5. Ultimately, the pleasurable benefits from psychoactive products may need to be

    For nearly three years now, the US, UK, and USSR have been working on the draft of a treaty that would ban all nuclear explosions (both peaceful applications and weapon tests) and institute verification and monitoring provisions to ensure compliance with the treaty. The status of the draft treaty is summarized. The question, Is a CTBT really in the interest of US national security. is analyzed with arguments used by both proponents and opponents of the CTBT. It is concluded that there are arguments both for and against a CTBT, but, for those whose approach to national security can be expressed as peace through preparedness, the arguments against a CTBT appear persuasive

    Seismological monitoring is one of the four technologies used by the International Monitoring System to verify compliance with the Comprehensive Nuclear-Test-Ban Treaty. When fully operational, two seismic networks, one primary (50 stations) and one auxiliary (120 stations), will enable global detection and event characterisation of sources with equivalent magnitude as low as 4. The basic principles of seismological theory and practice applied to verification are summarised, with particular emphasis on the new requirements imposed by the needs of the Treaty. (orig.) [de

    The post-nuclear period has rendered Pakistan's strategic calculations more vulnerable. The decision to go nuclear after seventeen days of debate have started proving costly to Pakistan. This is revealed by the economic crisis resulting out of the foreign currency shortage, leading the country to default on the payment of debts. The pressure imposed by the International Monetary Fund (IMF) and World Bank and their patrons to sign the Comprehensive Test Ban Treaty (CTBT) have exposed Pakistan's economic vulnerability. Under this growing pressure, many have started questioning the decision to go nuclear

    1994-06-01

    Full Text Available The problem of verifying compliance with a nuclear test ban treaty is mainly a technical one. However the problem of detecting, locating and identifying nuclear explosions has, since the late 1950s, been intimately involved with the political problems associated with negotiating a treaty. In fact there are few other areas in which policy, diplomacy and science have been so interwoven. This paper attempts to illustrate how technology can. be applied to solve some of the political problems which arise when considering the role of an On Site Inspection (OSI to determine whether or not a nuclear explosion, in violation of a treaty, has occurred or not. It is hoped that the reader, with a scientific background, but with little or no experience of treaty negotiations, will gain an. insight as to how technical matters can interact with political requirements. The demands made on scientists to provide technical support for negotiating and rnonitoring compliance of a treaty have increased significanfly over the last 40 years. This is a period in which a number of major treaties have contained a significant technical component e.g. the Limited Test Ban Treaty (Threshold Treaty and the Chemical Weapon Convention. This paper gives an indication of some of the political decisions which will have to be made and suggests some of the technical methods which are of value in the identification of a clandestine nuclear explosion.

  4. Forensic Seismology and the Comprehensive Nuclear-Test-Ban Treaty

    2009-05-01

    One application of forensic seismology is to help verify compliance with the Comprehensive Nuclear-Test-Ban Treaty. One of the challenges facing the forensic seismologist is to discriminate between the many thousands of earthquakes of potential interest each year and potential Treaty violations (underground explosions). There are four main methods: (a) ratio of body- to surface-wave magnitudes, (b) ratio of high-frequency P to S energy, (c) model-based methods, and (d) source depth. Methods (a) and (b) have an empirical basis. The weakness of methods (a)-(c) is the lack of an equivalent elastic source for an underground explosion fired in the range of geological media found around the world. Reliable routine source-depth determination has proved difficult. However, experience gained in the past decade at identifying suspicious seismic sources suggests that although no single method works all of the time, intelligent and original application of complementary methods is usually sufficient to satisfactorily identify the source in question.

  5. Test ban treaty verification with regional data: a review

    International Nuclear Information System (INIS)

    Pomeroy, P.W.; Best, W.J.; McEvilly, T.V.

    1982-01-01

    This paper summarizes the use of regional (Δ ≤ 30 0 ) seismic data in a test ban context for detecting, locating, identifying, and determining the yield of underground nuclear explosions. In many areas of the world (Eastern North America, Africa, Eastern USSR), Lg is the largest amplitude wave recorded on standard seismograph systems and thus is the most appropriate phase for monitoring small magnitude events. Excellent location capability for near-regional events has been demonstrated at the Norwegian small aperture array (NORESS) using Lg and P waves. Lg and other regional phases may contain information on source depth, but such information has not been exploited to date. Fifteen classes of regional discriminants are listed. Most have been tested only on limited data, usually from one geographic region and only one or two recording stations. No systematic analyses have been done to determine the best individual discriminant or combination of them. Preliminary evaluation of the use of Lg for yield determination suggests that regional waves hold promise in this application. Theoretical studies have contributed significantly to the understanding of propagation characteristics of regional waves but further studies are required emphasizing modeling for realistic anisotropic sources. The major conclusion of this study is that a systematic and comparative evaluation of all the proposed regional discriminants is now required, utilizing a common data base derived from all present-day test sites. This evaluation would suggest the optimal discrimination procedure using regional waves, and would also define areas of needed research. Without such an integrated evaluation, it is still possible to speculate, using existing results, on the most promising regional discriminants

    The benefits of a global ban on nuclear testing for international security and for protecting human health and the environment from radioactive fallout are obvious. The relevance of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) for climate change research may not, however, be evident at first glance. The CTBT bans all nuclear explosions on Earth. To monitor compliance with the Treaty, the CTBTO Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), is establishing a verification regime capable of detecting clandestine nuclear tests. As the only international body operating its own system of monitoring stations that literally spans the globe, the CTBTO is in a unique position to contribute to the UN's efforts in the area of climate knowledge.

    On-site inspections (OSI) are a key aspect of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Preparations to be able to conduct such inspections are going well. In particular, realistic major field exercises in Kazakhstan in 2008 and Jordan in 2014 enabled the Preparatory Commission of the Comprehensive Test-Ban-Treaty Organization (CTBTO) to learn valuable lessons regarding both the technical and human factors involved in being able to successfully implement the treaty's provisions.

    Cadwallader, Amy B; Murray, Bob

    2015-08-01

    Whenever athletes willfully or accidentally ingest performance-enhancing drugs or other banned substances (such as drugs of abuse), markers of those drugs can be detected in biological samples (e.g., biofluids: urine, saliva, blood); in the case of some drugs, that evidence can be apparent for many weeks following the last exposure to the drug. In addition to the willful use of prohibited drugs, athletes can accidentally ingest banned substances in contaminated dietary supplements or foods and inadvertently fail a drug test that could mean the end of an athletic career and the loss of a good reputation. The proliferation of performance-enhancing drugs and methods has required a corresponding increase in the analytical tools and methods required to identify the presence of banned substances in biofluids. Even though extraordinary steps have been taken by organizations such as the World Anti-Doping Agency to limit the use of prohibited substances and methods by athletes willing to cheat, it is apparent that some athletes continue to avoid detection by using alternative doping regimens or taking advantage of the limitations in testing methodologies. This article reviews the testing standards and analytical techniques underlying the procedures used to identify banned substances in biological samples, setting the stage for future summaries of the testing required to establish the use of steroids, stimulants, diuretics, and other prohibited substances.

    How do you monitor (verify) a CTBT? It is a difficult challenge to monitor the entire world for nuclear tests, regardless of size. Nuclear tests 'normally' occur underground, above ground or underwater. Setting aside very small tests (let's limit our thinking to 1 kiloton or more), nuclear tests shake the ground, emit large amounts of radioactivity, and make loud noises if in the atmosphere (or hydroacoustic waves if underwater)

    After W.W.II., the U.S. continued its program for the development of nuclear weapons. Winds carried radioactive debris far beyond the Nevada test site, and these fission products were deposited by rain, to enter the human food chain. The isotopes of greatest concern were Sr90 and I131, that, after ingestion, become concentrated in bone and thyroid respectively. There was a growing public anxiety about possible heath hazards posed by radiation from this fallout. In March 1958, the Greater St. Louis Citizens' Committee for Nuclear Information (C.N.I.) was formed. Among the leaders of C.N.I. were E. U. Condon and Barry Commoner. The aim of C.N.I. was ``to collect and distribute in the widest possible manner information which the public requires to understand the present and future problems which arise from potential large-scale use of nuclear weapons in war; testing of nuclear weapons; and nonmilitary uses of nuclear energy.'' In accordance with its objectives, members of C.N.I. gave many nontechnical talks, where we described the various forms of radiation and what was then known about the biological effects of radiation. Some of our members testified at Congressional committee hearings. We published a newsletter, initially titled Nuclear Information, and later Scientist and Citizen. In this presentation, I will describe some of the activities of this idealistic organization.

    Surface and underground mining operations generate seismic ground motions which are created by chemical explosions and ground failures. It may come as a surprise to some that the ground failures (coal bumps, first caves, pillar collapses, rockbursts, etc.) can send signals whose magnitudes are as strong or stronger than those from any mining blast. A verification system that includes seismic, infrasound, hydroacoustic and radionuclide sensors is being completed as part of the CTBT. The largest mine blasts and ground failures will be detected by this system and must be identified as distinct from signals generated by small nuclear explosions. Seismologists will analyze the seismic records and presumably should be able to separate them into earthquake-like and non earthquake-like categories, using a variety of so-called seismic discriminants. Non-earthquake essentially means explosion- or implosion-like. Such signals can be generated not only by mine blasts but also by a variety of ground failures. Because it is known that single-fired chemical explosions and nuclear explosion signals of the same yield give very similar seismic records, the non-earthquake signals will be of concern to the Treaty verification community. The magnitude of the mine-related events is in the range of seismicity created by smaller nuclear explosions or decoupled tests, which are of particular concern under the Treaty. It is conceivable that legitimate mining blasts or some mine-induced ground failures could occasionally be questioned. Information such as shot time, location and design parameters may be all that is necessary to resolve the event identity. In rare instances where the legitimate origin of the event could not be resolved by a consultation and clarification procedure, it might trigger on On-Site Inspection (OSI). Because there is uncertainty in the precise location of seismic event as determined by the International Monitoring System (IMS), the OSI can cover an area of up to 1

    Reviews of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) by the National Academy of Sciences concluded that the United States has the technical expertise and physical means to i) maintain a safe, secure and reliable nuclear-weapons stockpile without nuclear-explosion testing, and ii) effectively monitor global compliance once the Treaty enters into force. Moreover, the CTBT is judged to help constrain proliferation of nuclear-weapons technology, so it is considered favorable to U.S. security. Review of developments since the studies were published, in 2002 and 2012, show that the study conclusions remain valid and that technical capabilities are better than anticipated.

    In 2014 the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) undertook the Integrated Field Exercise (IFE) in Jordan. The exercise consisted of a simulated 0.5 – 2 kT underground explosion triggering an On-site Inspection (OSI) to search for evidence of a Treaty violation. This research evaluates two of the OSI techniques, including laboratory-based gamma-spectrometry of soil samples and in situ gamma-spectrometry for 17 particulate radionuclides indicative of nuclear weapon tests. The detection sensitivity is evaluated using real IFE and model data. It indicates that higher sensitivity laboratory measurements are the optimum technique during the IFE and OSI timeframes.

    The Laboratory Directed Research and Development (LDRD) Program at the DOE National Laboratories was established to ensure the scientific and technical vitality of these institutions and to enhance the their ability to respond to evolving missions and anticipate national needs. LDRD allows the Laboratory directors to invest a percentage of their total annual budget in cutting-edge research and development projects within their mission areas. We highlight a selected set of LDRD-funded projects, in chronological order, that have helped provide capabilities, people and infrastructure that contributed greatly to our ability to respond to technical challenges in support of test ban treaty verification and nonproliferation.

  1. Sensing the danger. Can tsunami early warning systems benefit from test ban monitoring?

    International Nuclear Information System (INIS)

    An editorial in the February 2005 edition of the Magazine for European Research pointed to the very issue of responsibility: Improvements are always possible, of course, but the very nature of a 'natural disaster' is that while not entirely absolving humans of responsibility it surpasses our means to deal with and even understand the forces at work. But science can help enhance our knowledge. For if there is one subject that the Asian tragedy has highlighted, it is the importance of putting in place coordinated early warning systems for earthquakes and, in particular, the absence of effective monitoring of tsunamis in the Indian Ocean. A concerted effort is now being made to develop a coordinated system of systems - bringing together organizations and initiatives that together can put in place an early warning system. The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), set-up to monitor adherence to the Comprehensive Nuclear-Test-Ban Treaty, is one organization seen to contribute to a coordinated early warning system

    Full Text Available The Comprehensive Nuclear-Test-Ban Treaty (CTBT is one of important international nuclear non-proliferation and disarmament measures. One of its pillars is the verification mechanism that has been built as an international system of nuclear testing detection to enable the control of observance of the obligations anchored in the CTBT. Despite the great relevance to the global non-proliferation and disarmament efforts, the CTBT is still not in force. The main aim of the article is to summarize the importance of the CTBT and its entry into force not only from the international relations perspective but also from the perspective of the technical implementation of the monitoring system.

    The Comprehensive Test Ban Treaty (CTBT) prohibits nuclear weapons testing at any yield. The detection and positive identification of any evasive test presents a challenge to the technical community, however. Low yield testing can be masked by normal background seismic noise or permissible chemical explosions for mining or other purposes. Cavity decoupling can reduce the seismic signal from the nuclear explosion by a factor of 50 or more. The combination of decoupling and high explosive masking represents a particular technical challenge for positive identification. To address this problem, a technical program in cooperation with the Kazakhstan National Nuclear Center has been initiated to conduct a series of tests in the Balapan area of the Semipalatinsk Test Site to provide fundamental data on the depth of burial effects on seismic signals emanating from an explosion. If the depth of burial can be positively determined from the characteristics of the seismic waveform, near-surface mining blasts can be distinguished from deep underground evasive nuclear explosions, thus eliminating the capability to easily mask the nuclear event. This paper will briefly describe the basic concepts of some evasive nuclear testing options and discuss the cooperative test program that is being carried out to improve the capability to positively identify such tests. The paper will also discuss possible additional cooperative tests that might be done in 1998 to further improve the identification capability

  5. EU sales ban on new cosmetics tested on animals: impact on alternative methods, WTO implications and animal welfare aspects.

    Science.gov (United States)

    Ruhdel, Irmela W

    2004-06-01

    In 1993, the European Union (EU) adopted Directive 93/35/EEC, calling for a sales ban on new cosmetic products containing ingredients tested on animals after 1 January, 1998, provided that alternative methods had been developed by then. In May 2000, for the second time, the European Commission postponed that ban. The Commission justified the repeated postponement of the sales ban by saying that no animal-free methods were available, although three in vitro methods were scientifically approved in 1997. With three years delay, these methods have been published and therefore "made available" in the EU. OECD acceptance is still awaited. Another reason for the postponement was the fear of possible World Trade Organisation (WTO) conflicts. However, according to WTO rules, the protection of public morality or animal health could justify a restriction of the free trade principle. From the animal welfare point of view, an unqualified EU sales ban, combined with an animal testing ban, would provide the incentive to further promote the development and acceptance of alternative methods and to prove that ethical standards are legitimate concerns under WTO rules.

  6. Inverse transport for the verification of the Comprehensive Nuclear Test Ban Treaty

    J.-P. Issartel

    2003-01-01

    Full Text Available An international monitoring system is being built as a verification tool for the Comprehensive Test Ban Treaty. Forty stations will measure on a worldwide daily basis the concentration of radioactive noble gases. The paper introduces, by handling preliminary real data, a new approach of backtracking for the identification of sources of passive tracers after positive measurements. When several measurements are available the ambiguity about possible sources is reduced significantly. The approach is validated against ETEX data. A distinction is made between adjoint and inverse transport shown to be, indeed, different though equivalent ideas. As an interesting side result it is shown that, in the passive tracer dispersion equation, the diffusion stemming from a time symmetric turbulence is necessarily a self-adjoint operator, a result easily verified for the usual gradient closure, but more general.

    Recognizing that the debate in the U.S. Senate on whether to ratify the Comprehensive Test Ban Treaty (CTBT) could benefit from a clear analysis of the technical limits to monitoring nuclear explosions, AGU joined with the Seismological Society of America (SSA) to carry out such an analysis. In the following policy statement, approved by both societies, seismologists speak with essentially one voice about this crucial aspect of the CTBT. This is the first time that AGU has prepared a policy statement jointly with another society, and this is the first policy statement SSA has adopted.The policy regarding AGU's procedures for developing position statements on public issues, the Union's role in advocacy of the statements, and all current AGU position statements are available online at http://www.agu. org/sci_soc/policy/sci_ pol.html.

    Hydroacoustics is one of the four monitoring technologies of the International Monitoring System (IMS) established under the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The hydroacoustic network, designed to monitor the major world oceans, contains eleven stations located with an emphasis on the vast ocean areas of the Southern Hemisphere. Two different sensing techniques are employed; hydrophone sensors, which effectively cover large ocean areas, but are quite complex and expensive, and seismic detectors on small islands which are less effective, but considerably simpler and cheaper. The hydroacoustic stations transmit data in real time via satellite to the International Data Centre (IDC). The IDC analyses the hydroacoustic data in combination with the other three technologies to produce bulletins of detected events for the States Party to the Treaty. (orig.) [de

    1996-03-01

    To monitor compliance with a Comprehensive Test Ban Treaty (CTBT), a sensing network, referred to as the International Monitoring System (IMS), is being deployed. Success of the IMS depends on both its ability to preform its function and the international community`s confidence in the system. To ensure these goals, steps must be taken to secure the system against attacks that would undermine it; however, it is not clear that consensus exists with respect to the security requirements that should be levied on the IMS design. In addition, CTBT has not clearly articulated what threats it wishes to address. This paper proposes four system-level threats that should drive IMS design considerations, identifies potential threat agents, and collects into one place the security requirements that have been suggested by various elements of the IMS community. For each such requirement, issues associated with the requirement are identified and rationale for the requirement is discussed.

    1994-12-31

    The large amounts of chemical explosives used worldwide in mining, quarrying, and civil engineering projects presents a challenge for policy makers molding a test ban, since their use could provide the necessary cover for a clandestine nuclear test. The Non-Proliferation Experiment (NPE) seeks to measure certain differences between an underground nuclear test and a chemical explosion in the same geology. Two chemical explosions were detonated at the Nevada Test Site to compare their signatures with previous nuclear tests. This conference presents results of these tests and discusses implications for test ban treaties. Conference papers are divided into the following sections: Background; Test preparations; EOS and code simulations; Rainier Mesa structure; Ground motion measurements; Non-seismic technologies; On-site inspection technologies; and a panel discussion. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

  12. Should Australia Ban the Use of Genetic Test Results in Life Insurance?

    2017-12-01

    Full Text Available Under current Australian regulation, life insurance companies can require applicants to disclose all genetic test results, including results from research or direct-to-consumer tests. Life insurers can then use this genetic information in underwriting and policy decisions for mutually rated products, including life, permanent disability, and total income protection insurance. Over the past decade, many countries have implemented moratoria or legislative bans on the use of genetic information by life insurers. The Australian government, by contrast, has not reviewed regulation since 2005 when it failed to ensure implementation of recommendations made by the Australian Law Reform Commission. In that time, the Australian life insurance industry has been left to self-regulate its use of genetic information. As a result, insurance fears in Australia now are leading to deterred uptake of genetic testing by at-risk individuals and deterred participation in medical research, both of which have been documented. As the potential for genomic medicine grows, public trust and engagement are critical for successful implementation. Concerns around life insurance may become a barrier to the development of genomic health care, research, and public health initiatives in Australia, and the issue should be publicly addressed. We argue a moratorium on the use of genetic information by life insurers should be enacted while appropriate longer term policy is determined and implemented.

    The Comprehensive Test Ban Treaty (CTBT) is gaining renewed attention in light of growing worldwide interest in mitigating risks of nuclear weapons proliferation and testing. Since the International Monitoring System (IMS) installed the first suite of sensors in the late 1990's, the IMS network has steadily progressed, providing valuable support for event diagnostics. This progress was highlighted at the recent International Scientific Studies (ISS) Conference in Vienna in June 2009, where scientists and domain experts met with policy makers to assess the current status of the CTBT Verification System. A strategic theme within the ISS Conference centered on exploring opportunities for further enhancing the detection and localization accuracy of low magnitude events by drawing upon modern tools and techniques for machine learning and large-scale data analysis. Several promising approaches for data exploitation were presented at the Conference. These are summarized in a companion report. In this paper, we introduce essential concepts in machine learning and assess techniques which could provide both incremental and comprehensive value for event discrimination by increasing the accuracy of the final data product, refining On-Site-Inspection (OSI) conclusions, and potentially reducing the cost of future network operations.

    A method of weapon detection for the Comprehensive nuclear-Test-Ban-Treaty (CTBT) consists of monitoring the amount of radioxenon in the atmosphere by measuring and sampling the activity concentration of 131m Xe, 133 Xe, 133m Xe, and 135 Xe by radionuclide monitoring. Several explosion samples were simulated based on real data since the measured data of this type is quite rare. These data sets consisted of different circumstances of a nuclear explosion, and are used as training data sets to establish an effective classification model employing state-of-the-art technologies in machine learning. A study was conducted involving classic induction algorithms in machine learning including Naive Bayes, Neural Networks, Decision Trees, k-Nearest Neighbors, and Support Vector Machines, that revealed that they can successfully be used in this practical application. In particular, our studies show that many induction algorithms in machine learning outperform a simple linear discriminator when a signal is found in a high radioxenon background environment.

    1984-01-01

    This dissertation is a narrative history and organizational study of the formative years of Women Strike for Peace (1961-1963) and its campaign for a nuclear test ban treaty. WSP, a grass roots, participatory movement of American Women, was born on November 1, 1961 when an estimated 50,000 women in 60 communities across the nation walked out of their kitchens and off their jobs in a one day protest against Russian and American nuclear policies. In the process of transforming this one day strike into a national woman's movement, WSP developed a feminine political style characterized by an anti-heirarchical, anti-organizational format, simple, womanly rhetoric, and spontaneous, innovative national and international direct action. At a time when foreign policy dissenters were dismissed by the press and the public either as commies or kooks, the image that WSP projected to respectable middle-class, middle-aged peace mothers wearing white gloves and flowered hats while picketing the White House to save their children from nuclear holocaust caught the favorable attention of large sections of the media, the public, and even the President. Through an investigation of the program, internal debates, rhetoric, organizational structure, and tactics of WSP, along with the backgrounds of its leaders and members, this study uncovers the political and gender consciousness of the women who joined the movement

  17. Role reversal and problem solving in international negotiations: the Partial Nuclear Test Ban case

    1978-01-01

    To facilitate finding bargaining space and to reinforce cooperative potential, a number of analysts have promoted the use of role reversal and problem solving. Role reversal involves restating the positions of one's adversary to demonstrate understanding and to develop empathy, while problem solving involves searching for alternatives that promote joint interests. The case of the negotiations in the Eighteen Nation Disarmament Conference from 1962--1963 leading to the Partial Nuclear Test Ban Treaty provided the context for examining bargaining relationships involving role reversal and problem solving. Interactions among the United States, the United Kingdom, and the Soviet Union, as recorded in transcripts of 112 sessions, were coded using Bargaining Process Analysis II, a content analysis instrument used to classify negotiation behaviors. Role reversal was measured by the frequency of paraphrases of the adversary's positions. Problem solving was measured by the frequency of themes promoting the exploration of alternatives and the search for mutually beneficial outcomes. The findings on the use of paraphrasing suggest that it can be used to restrict exploration as well as to promote it. The exploratory focus of problem solving was somewhat limited by its use in association with demands, suggesting that problem solving was interpreted as a sign of weakness

    The mission of the Comprehensive Nuclear-Test-Ban Treaty International Data Centre (IDC) is to: (a) acquire data over a Global Communications Infrastructure from a global network of 337 facilities of the International Monitoring Systems (IMS), (b) to process and analyze these data, and (c) to provide the IMS data, IDC products and services to Member States. In effect, the IDC symbolizes a new brand of arms control for the information age, leveraging Internet communications, knowledge-based data fusion, graphical decision support systems and Web-based user interfaces to achieve its mission. During 2000, the IDC was disseminating products based on data from about 90 seismic, hydroacoustic, infrasound and radionuclide stations of the future network. The number of events in the reviewed seismo-acoustic bulletins ranged from 40 to 360 each day. On average, some 200 radionuclide spectra were processed and analysed each month. Users from 45 Member States received an average of close to 18,000 data and product deliveries per month from the IDC. As the IDC continues to prepare for entry-into-force of the CTBT, it will continue to integrate the state-of-the-art in science and technology in order to meet the demands of the increasing volume of new types of IMS data, expanded IDC services, and a growing base of users.

    SHAMAN is an expert for qualitative and quantitative radionuclide identification in gamma spectrometry. SHAMAN requires as input the calibrations, peak search, and fitting results from reliable spectral analysis software, such as SAMPO. SHAMAN uses a comprehensive reference library with 2600 radionuclides and 80 000 gamma-lines, as well as a rule base consisting of sixty inference rules. Identification results are presented both via an interactive graphical interface and in the form of configurable text reports. An organization has been established for monitoring the recent Comprehensive Test Ban Treaty. For radionuclide monitoring, 80 stations will be set up around the world. Air-filter gamma-spectra will be collected from these stations on a daily basis and they will need to be reliably analyzed with minimum turnaround time. SHAMAN is currently being evaluated within the prototype monitoring system as an automated radionuclide identifier, in parallel with existing radionuclide identification software. In air-filter monitoring, very low concentrations of radionuclides are measured from bulky sources in close geometry and with long counting time. In this case true coincidence summing and self-absorption become important factors. SHAMAN is able to take into account these complicated phenomena, and the results it produces have been found to be very reliable and accurate. (author)

The detection sensitivity is evaluated using real IFE and model data. It indicates that higher sensitivity laboratory measurements are the optimum technique during the IFE and within the Treaty/Protocol-specified OSI timeframes. - Highlights: • The 2014 Integrated Field Exercise occurred in Jordan. • The detection sensitivity for two On-site Inspection techniques was evaluated. • The techniques search for 17 particulate radionuclides indicative of nuclear explosions. • Laboratory-based gamma-spectrometry of soil samples was the optimum technique.

  1. The Nuclear Non-Proliferation Treaty and the Comprehensive Nuclear-Test-Ban Treaty, the relationship

    International Nuclear Information System (INIS)

    Graham, Thomas Jr.

    2014-01-01

    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

  2. Structure and behavior as determinants: United States nuclear test ban and chemical and biological arms control policy

    US efforts to control chemical and biological warfare and nuclear testing are examined with the aim of explaining the paucity of US backed agreements in these areas. Two theoretical perspectives, the behavioral and structural approaches, are used to explore US arms control outcomes. In the behavioral approach, the effects of governmental organization and the bargaining dynamics of policy-making elites with different cognitive styles are posited as important influences on US nuclear test ban and chemical and biological arms control policy outcomes. The behavioral perspective accounts for the timing of all US failed and successful entries (with one exception) into nuclear test bans and chemical and biological warfare restraints. A shortcoming of the behavior approach, however, is that it tends to overemphasize the chances for successful US entry into nuclear test and chemical and biological warfare limitations. Analysis of the same events from the structural perspective helps to correct for expectations generated by behavioral variables for a higher success rate than ultimately resulted. In the structural approach, the focus is on the effect of the organization of international politics on US nuclear test ban and chemical and biological arms control policy outcomes

    The Department of Energy (DOE) is responsible for the United States Government`s (USG) research and development (R&D) functions for monitoring nuclear explosions in the context of a Comprehensive Test Ban Treaty (CTBT). This responsibility includes the November 1993 transfer of the Department of Defense`s (DoD) CTBT R&D responsibility to DOE. The DOE research program builds on the broad base of USG expertise developed historically and includes R&D for detecting, locating, identifying, and characterizing nuclear explosions in all environments. The Office of Research and Development (NN-20), within the Department of Energy`s Office of Nonproliferation and National Security, formulates and executes the efforts necessary to meet the Department`s responsibilities. The following DOE laboratories as a team will support NN-20 in implementing the program plan: Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Pacific Northwest Laboratory, and Sandia National Laboratories. DOE has committed to a cooperative program that draws upon the core competencies of the national laboratories and upon the strengths of other government agencies and the private sector (academia and industry). The integration of resources under a common direction will allow the program to be flexible and responsive to changing technical and policy requirements while maximizing the effectiveness of funding appropriations. DOE will develop and demonstrate appropriate technologies, algorithms, procedures, and integrated systems in a cost-effective and timely manner. The program comprises seismic, radionuclide, hydroacoustic, and infrasound monitoring; on-site inspection; space-based monitoring; and automated data processing elements.

    Underground nuclear explosions produce a unique but evanescent set of radionuclide gases that potentially can be used in the context of an on-site, test-ban monitoring program to differentiate them from other detected events such as earthquakes or mining activity. In Part I of this report we describe an experiment to evaluate the upward transport of gases from an underground explosion using two gas tracers with very different diffusivities that were released in a 400-m-deep, chemical explosive detonation. The less diffusive (more massive) tracer was detected on a nearby geologic fault 50 days following the detonation while the more diffusive tracer was detected 375 days after release. Computer simulations indicate that the arrival time and the chromatographic behavior of transport are characteristic of barometrically induced flow in a fractured, porous matrix regime. For a hypothetical 1-kiloton fission explosion subject to the same weather and gas transport conditions of the chemical explosion, simulations predict the detectability of argon-37 after 80 days in spite of depletion by radioactive decay. Largely because of the earlier arrival of xenon-133, owing to its lower binary gas diffusivity, the exceedingly short lived isotope should also be detectable - arriving about 30 days earlier than argon. In Part II we consider that our prediction of the detectability of argon and xenon is based upon the small volume (0.00001 m 3 ) sampling technique of the NPE tracer-gas sampling study while actual sampling for radionuclides would involve drawing much larger volume (possibly 0.1-1 m 3 ) gas samples from the near-surface. Extraction of such a large volume of gas from 1-5 meter depths in the soil raises the possibility of significant atmospheric infiltration, leading to substantial dilution of the extracted gas sample. However, an infiltration experiment suggests that significant dilution would not, in fact, occur at the most prolific sampling stations of the earlier gas

    It is disappointing that an important treaty that has been high on the international agenda ever since it was first introduced by the Indian Prime Minister Nehru in 1954, is still not in force. The fate of the treaty depends on political developments, especially in the key countries listed above. The treaty has, however, already established a global norm against nuclear testing, a norm that only India and Pakistan have broken. The Preparatory Commission and its Provisional Technical Secretariat (PTS) were established in Vienna in 1996 to implement the treaty and to prepare for its entry into force. The Preparatory Commission has enjoyed a close cooperation among the States Signatories in implementing the treaty and its elaborate verification regime. The key task for the PTS is to establish the verification arrangements specified in the treaty. The PTS has a staff of 300 people and a yearly budget of $100 million. The treaty demands the most elaborate international verification regime ever created. The assessment of compliance or non-compliance is a political process among the States. The verification regime provided by the treaty facilitates this process by giving all States a common base of information to use in their assessment. Individual treaty parties might have additional national technical means and additional capabilities of their own to analyze raw data. The verification regime consists of two complementary parts; an International Monitoring System and an On-Site Inspection regime. In addition, there are provisions for consultations and clarification. The International Monitoring System has a global reach with a total of 321 monitoring stations in 92 countries. It uses four different technologies to monitor all possible testing environments underground, in the oceans and in the atmosphere

    1999-01-01

    With the signing of a comprehensive test ban treaty in 1996, the ability to detect the presence of anthropogenic radionuclides in the atmosphere for verification purposes is increasingly important. A trigger detector is a concept designed to aid in this purpose by giving timely notice of suspicious concentrations of radionuclides in the atmosphere adjacent to a radionuclide monitoring station (RMS) (DeGeer, Nuclear Detection Group, Division of Nuclear Weapons Physics, National Defence Research Establishment, S-17290 Stockholm, Sweden, De Geer, Paper presented at the ARPA sponsored meeting on CTBT Monitoring Technologies, San Diego, 26-29 September 1994). In this research, the evaluation and performance analysis of two different trigger detectors was studied. Point source experiments were performed to characterize the detector response. Limits of detection for each detector were determined using a simulated atmosphere (∼100 gal of water) contaminated with a gamma-ray emitting radioisotope. Three different analytical models of radioactive clouds were developed to predict detectability: (1) uniformly contaminated hemisphere; (2) uniformly contaminated slabs; and (3) a series of infinitely long line sources (representing rectangular segments of a uniformly contaminated atmosphere). The simulation of a contaminated atmosphere yielded a detectable concentration, for 1.0 MeV photons, of approximately 0.5 Bq/m 3 by the NaI detector. The study indicates that the NaI crystal is the detector of choice for a RMS triggering system

    Global monitoring for relevant radionuclides in the atmosphere serves as part of the International Monitoring System to verify compliance with the Comprehensive Nuclear-Test-Ban-Treaty (CTBT). Atmospheric transport modelling can be applied to support these measurements and to get indications for possible source locations of detected relevant anthropogenic nuclides. This paper puts a focus on those issues that are of relevance to the International Data Centre (IDC). Possible methods of atmospheric transport modelling are outlined. The current tentative implementation at the IDC is described here. (orig.) [de

    The radionuclide monitoring network is one of the four technical components of the compliance-verification system associated with the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Concentrations of radionuclides in the air are monitored at 80 stations worldwide from which spectral and counting data, together with meteorological and state-of-health data, are transmitted through a Global Communication Infrastructure to the Provisional Technical Secretariat in Vienna where the data are analyzed and reported as bulletins for States Parties. Support is provided by 16 Radionuclide Laboratories, which conduct sample analyses if necessary. (orig.) [de

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

    The use of the xenon isotopes for detection of nuclear explosions is of great interest for monitoring compliance with the comprehensive nuclear-test-ban treaty (CTBT). Recently, the automated radioxenon sampler-analyzer (ARSA) was tested at the Institute for Atmospheric Radioactivity (IAR) in Freiburg, Germany to ascertain its use for the CTBT by comparing its results to laboratory-based analyses, determining its detection sensitivity and analyzing its results in light of historical xenon isotope levels and known reactor operations in the area. Xe-133 was detected nearly every day throughout the test at activity concentrations ranging between approximately 0.1 mBq/m 3 to as high as 120 mBq/m 3 . Xe-133m and 135 Xe were also detected occasionally during the test at concentrations of less than 1 to a few mBq/m 3

    These proceedings contain papers prepared for the 21st Seismic Research Symposium: Technologies for Monitoring The Comprehensive Nuclear-Test-Ban Treaty, held 21-24 September 1999 in Las Vegas, Nevada. These papers represent the combined research related to ground-based nuclear explosion monitoring funded by the National Nuclear Security Administration (NNSA), Defense Threat Reduction Agency (DTRA), Air Force Technical Applications Center (AFTAC), Department of Defense (DoD), the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), and other invited sponsors. The scientific objectives of the research are to improve the United States capability to detect, locate, and identify nuclear explosions. The purpose of the meeting is to provide the sponsoring agencies, as well as potential users, an opportunity to review research accomplished during the preceding year and to discuss areas of investigation for the coming year. For the researchers, it provides a forum for the exchange of scientific information toward achieving program goals, and an opportunity to discuss results and future plans. Paper topics include: seismic regionalization and calibration; detection and location of sources; wave propagation from source to receiver; the nature of seismic sources, including mining practices; hydroacoustic, infrasound, and radionuclide methods; on-site inspection; and data processing.

    2010-07-01

    The object and purpose of the CTBT is to ban comprehensively nuclear weapon test explosions and any other nuclear explosion in any environment in an effectively verifiable manner. The CTBT aims at eliminating nuclear weapons by constraining the development and qualitative improvement of new or more advanced nuclear weapons. It plays a crucial role in the prevention of nuclear proliferation and in nuclear disarmament, thus contributing to a safer and more secure world. When the Treaty enters into force it will establish a treaty-implementing body (the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO)), including an on-site inspection mechanism and confidence-building measures as well as an International Monitoring System (IMS) and International Data Centre (IDC). The IMS and IDC are already being created and are being provisionally operated during the preparatory phase by the Preparatory Commission for the CTBTO and its Provisional Technical Secretariat in Vienna. Seismic, hydroacoustic, infrasound and radionuclide data are collected through the stations of the IMS and transmitted to Member States via the IDC. The IDC also processes the raw data received from the stations to derive objective products and services which will support the Treaty verification responsibilities. If the collected and analysed data indicate an ambiguous event, States may address concerns about possible noncompliance with the Treaty through a consultation and clarification process after it enters into force and may request an on-site inspection by the CTBTO.

  16. The banning of sportsmen and women who fail drug tests is unjustifiable.

    2013-01-01

    The use of performance enhancing drugs among elite athletes has been in the headlines recently, particularly with Lance Armstrong's fall from grace and his admission about widespread doping. Many argue that the use of drugs confers an unfair advantage and is ultimately dangerous to the health of the athletes. Others, like Professor Shuster, argue that the use of drugs is no different from other techniques employed by athletes to boost their performance: swimmers shaving their body hair; skiers wearing sleek body armour; archers and shooters having laser eye surgery to improve their accuracy. Professor Shuster puts forward the provocative argument that since 'there is no acceptable proof (that) drugs improve competitive performance and their use is no different from accepted sports practice, banning them is wrong and immoral.' JW Devine argues the other side, that the use of performance enhancing drugs poses a 'significant risk to the health of athletes' and perhaps more importantly, 'threatens to undermine the very purpose of sport' by disrupting the 'balance of excellences'.

    This paper is intended to serve as a scientific basis to start discussions of the available environmental sampling techniques and equipment that have been used in the past that could be considered for use within the context of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) on-site inspections (OSI). This work contains information on the techniques, equipment, costs, and some operational procedures associated with environmental sampling that have actually been used in the past by the United States for the detection of nuclear explosions. This paper also includes a discussion of issues, recommendations, and questions needing further study within the context of the sampling and analysis of aquatic materials, atmospheric gases, atmospheric particulates, vegetation, sediments and soils, fauna, and drill-back materials.

    In preparation for verification of the Comprehensive Nuclear-Test-Ban-Treaty, automated radioxenon monitoring is performed in two distinctive environments: Ottawa and Tahiti. These sites are monitored with SPALAX (Systeme de Prelevement d'air Automatique en Ligne avec l'Analyse des radioXenons) technology, which automatically extracts radioxenon from the atmosphere and measures the activity concentrations of (131m,133m,133,135)Xe. The resulting isotopic concentrations can be useful to discern nuclear explosions from nuclear industry xenon emissions. Ambient radon background, which may adversely impact analyser sensitivity, is discussed. Upper concentration limits are reported for the apparently radioxenon free Tahiti environment. Ottawa has a complex radioxenon background due to proximity to nuclear reactors and medical isotope facilities. Meteorological models suggest that, depending on the wind direction, the radioxenon detected in Ottawa can be characteristic of the normal radioxenon background in the Eastern United States, Europe, and Japan or distinctive due to medical isotope production.

    On-Site Inspection (OSI) is a key component of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Measurements of radionuclide isotopes created by an underground nuclear explosion are a valuable signature of a Treaty violation. Argon-37 is produced from neutron interaction with calcium in soil, 40Ca(n,α)37Ar. For OSI, the 35-day half-life of 37Ar provides both high specific activity and sufficient time for completion of an inspection before decay limits sensitivity. This paper presents a low-background internal-source gas proportional counter with an 37Ar measurement sensitivity level equivalent to 45.1 mBq/SCM in whole air.

    A method of high performance liquid chromatography-linear ion trap/orbitrap highresolution mass spectrometry (HPLC-LTP/Orbitrap MS) was ued to screen and confirm-banned azo colorants in textiles rapidly. The analytes were reduced to carcinogenic aromatic amines with sodium dithionite in citrate buffer solution. The reduced solution was extracted bydiatomite, and loadd onto an Acquity UPLC BEH C18 column (50 mm x 2.1 MM. 1.7 microm) with a gradient elution of methanol and 0.1% (v/v) methane acid aqueous solution, and finally detected by linear ion trap/orbitrap high-resolution mass spectrometry in positive ESI mode. In mass spectrometry method, the MS spectrum of high-resolution and the collision induced dissociation (CID) spectrum of data-dependent scan mode were used for screening analysis and conformation, respectively. The calibration curves showed a good linearity in the range of 0.05 -2.00 mg/b, and the correlation coefficients (r) were higher than 0.99. By detecting spiked samples, the limits of quantification were 0.08 mg/kg for all the residues and the recoveries were in the range of 65.5% - 111.5% with the relative standard deviations (RSDs) between 0.87% and 2.49%. The results indicate that the method is simple, rapid, sensitive and suitable for the qualitative and quantitative analysis of carcinogenic aromatic amines in textiles.

    South Africa signed and ratified the Comprehensive Nuclear Test-Ban-Treaty (CTBT) and accordingly made commitments to the Organization (CTBTO). Of the obligations are the establishment of a Radionuclide Laboratory, the design, installation and operation and maintenance of a radionuclide particulate and noble-gas monitoring station and the nomination of one radionuclide specialist South African to serve on an international team for On-Site Inspection (OSI). The last to provide expertise when the worldwide monitoring network provides strong indications that an illegal nuclear test has been performed at the territory of a State Party. The inspection team will be equipped with amongst others radiation monitors and nuclide specific measuring equipment limited to report on specific radionuclides agreed upon by all State Parties. In real-time operational circumstances one may assume that all members of the team will not be registered radiation workers and accordingly be regarded as members of the public when radiation hazard is to be evaluated. Radionuclides of interest are categorized and radiological risk to the OSI-team due to inhalation of airborne radioactive particulate matter during the survey at the site of an anticipated nuclear test is evaluated. From this study recommendations will be made to the CTBTO for possible implementation of portable sampling and analysis equipment to allow on-site evaluation of the potential internal exposure of OSI-team members.

    Casey, Leslie A.

    1994-01-01

    This newsletter contains reprinted papers discussing technology options and associated measures for monitoring a Comprehensive Test Ban Treaty (CTBT). These papers were presented to the Conference on Disarmament (CD) in May and June 1994. An interagency Verification Monitoring Task Force developed the papers. The task force included participants from the Arms Control and Disarmament Agency, the Department of Defense, the Department of Energy, the Intelligence Community, the Department of Interior, and the Department of State. The purpose of this edition of Arms Control and Nonproliferation Technologies is to share these papers with the broad base of stakeholders in a CTBT and to facilitate future technology discussions. The papers in the first group discuss possible technology options for monitoring a CTBT in all environments (underground, underwater, atmosphere, and space). These technologies, along with on-site inspections, would facilitate CTBT monitoring by treaty participants. The papers in the second group present possible associated measures, e.g., information exchanges and transparency measures, that would build confidence among states participating in a CTBT.

    The Integrated Field Exercise of 2014 (IFE14) was a field event held in the Hashemite Kingdom of Jordan (with concurrent activities in Austria) that tested the operational and technical capabilities of a Comprehensive Test Ban Treaty's (CTBT) on-site inspection (OSI). During an OSI, up to 40 inspectors search a 1000km2 inspection area for evidence of a nuclear explosion. Over 250 experts from ~50 countries were involved in IFE14 (the largest simulation of an OSI to date) and worked from a number of different directions, such as the Exercise Management and Control Teams to execute the scenario in which the exercise was played, to those participants performing as members of the Inspection Team (IT). One of the main objectives of IFE14 was to test Treaty allowed inspection techniques, including a number of geophysical and remote sensing methods. In order to develop a scenario in which the simulated exercise could be carried out, a number of physical features in the IFE14 inspection area were designed and engineered by the Scenario Task Force Group (STF) that the IT could detect by applying the geophysical and remote sensing inspection technologies, as well as other techniques allowed by the CTBT. For example, in preparation for IFE14, the STF modeled a seismic triggering event that was provided to the IT to prompt them to detect and localize aftershocks in the vicinity of a possible explosion. Similarly, the STF planted shallow targets such as borehole casings and pipes for detection by other geophysical methods. In addition, airborne technologies, which included multi-spectral imaging, were deployed such that the IT could identify freshly exposed surfaces, imported materials and other areas that had been subject to modification. This presentation will introduce the CTBT and OSI, explain the IFE14 in terms of goals specific to geophysical and remote sensing methods, and show how both the preparation for and execution of IFE14 meet those goals.

    The Integrated Field Exercise of 2014 (IFE14) was an event held in the Hashemite Kingdom of Jordan (with concurrent activities in Austria) that tested the operational and technical capabilities of an on-site inspection (OSI) within the CTBT verification regime. During an OSI, up to 40 international inspectors will search an area for evidence of a nuclear explosion. Over 250 experts from ~50 countries were involved in IFE14 (the largest simulation of a real OSI to date) and worked from a number of different directions, such as the Exercise Management and Control Teams (which executed the scenario in which the exercise was played) and those participants performing as members of the Inspection Team (IT). One of the main objectives of IFE14 was to test and integrate Treaty allowed inspection techniques, including a number of geophysical and remote sensing methods. In order to develop a scenario in which the simulated exercise could be carried out, suites of physical features in the IFE14 inspection area were designed and engineered by the Scenario Task Force (STF) that the IT could detect by applying the geophysical and remote sensing inspection technologies, in addition to other techniques allowed by the CTBT. For example, in preparation for IFE14, the STF modeled a seismic triggering event that was provided to the IT to prompt them to detect and localize aftershocks in the vicinity of a possible explosion. Similarly, the STF planted shallow targets such as borehole casings and pipes for detection using other geophysical methods. In addition, airborne technologies, which included multi-spectral imaging, were deployed such that the IT could identify freshly exposed surfaces, imported materials, and other areas that had been subject to modification. This presentation will introduce the CTBT and OSI, explain the IFE14 in terms of the goals specific to geophysical and remote sensing methods, and show how both the preparation for and execution of IFE14 meet those goals.

    The forthcoming luminosity upgrade of LHC to super-LHC (sLHC) will increase the expected background rate in the forward region of the ATLAS Muon Spectrometer by approximately the factor of five. Some of the present Muon Spectrometer components will fail to cope with these high rates and will have to be replaced. The results of a test of a device consisting of Thin Gap Chambers (TGC) and a fast small-diameter Muon Drift Tube Chamber (sMDT) using the 180 GeV/c muons at the SPS-H8 muon beam at CERN are presented. The goal of the test was to study the combined TGC-sMDT system as tracking and triggering device in the ATLAS muon spectrometer after high-luminosity upgrades of the LHC. The analysis of the recorded data shows a very good correlation between the TGC and sMDT track position and inclination. This technology offers the combination of trigger and tracking and has good angular and spatial resolutions. The angular resolution is 0.4 mrad for each system individually. For the spatial resolution, the width of t...

  10. Uncertainty quantification for discrimination of nuclear events as violations of the comprehensive nuclear-test-ban treaty

    Enforcement of the Comprehensive Nuclear Test Ban Treaty (CTBT) will involve monitoring for radiologic indicators of underground nuclear explosions (UNEs). A UNE produces a variety of radioisotopes which then decay through connected radionuclide chains. A particular species of interest is xenon, namely the four isotopes 131m Xe, 133m Xe, 133 Xe, and 135 Xe. Due to their half lives, some of these isotopes can exist in the subsurface for more than 100 days. This convenient timescale, combined with modern detection capabilities, makes the xenon family a desirable candidate for UNE detection. Ratios of these isotopes as a function of time have been studied in the past for distinguishing nuclear explosions from civilian nuclear applications. However, the initial yields from UNEs have been treated as fixed values. In reality, these independent yields are uncertain to a large degree. This study quantifies the uncertainty in xenon ratios as a result of these uncertain initial conditions to better bound the values that xenon ratios can assume. We have successfully used a combination of analytical and sampling based statistical methods to reliably bound xenon isotopic ratios. We have also conducted a sensitivity analysis and found that xenon isotopic ratios are primarily sensitive to only a few of many uncertain initial conditions. - Highlights: • Analytical solutions of radioxenon radioactivities and their uncertainties from complex chain reactions. • A generalized method for uncertainty quantification for isotopic ratios in user-defined nuclear decay chains. • Global sensitivity analysis for identifying influential independent yields to xenon isotopic ratios. • Probabilistic discrimination of nuclear explosions from civilian applications

    Abstract The International Monitoring System (IMS) is part of the verification regime for the Comprehensive Nuclear-Test-Ban-Treaty Organization (CTBTO). At entry-into-force, half of the 80 radionuclide stations will be able to measure concentrations of several radioactive xenon isotopes produced in nuclear explosions, and then the full network may be populated with xenon monitoring afterward (Bowyer et al., 2013). Fission-based production of 99Mo for medical purposes also releases radioxenon isotopes to the atmosphere (Saey, 2009). One of the ways to mitigate the effect of emissions from medical isotope production is the use of stack monitoring data, if it were available, so that the effect of radioactive xenon emissions could be subtracted from the effect from a presumed nuclear explosion, when detected at an IMS station location. To date, no studies have addressed the impacts the time resolution or data accuracy of stack monitoring data have on predicted concentrations at an IMS station location. Recently, participants from seven nations used atmospheric transport modeling to predict the time-history of 133Xe concentration measurements at an IMS station in Germany using stack monitoring data from a medical isotope production facility in Belgium. Participants received only stack monitoring data and used the atmospheric transport model and meteorological data of their choice. Some of the models predicted the highest measured concentrations quite well (a high composite statistical model comparison rank or a small mean square error with the measured values). The results suggest release data on a 15 min time spacing is best. The model comparison rank and ensemble analysis suggests that combining multiple models may provide more accurate predicted concentrations than any single model. Further research is needed to identify optimal methods for selecting ensemble members and those methods may depend on the specific transport problem. None of the submissions based only

  14. Multiphase, multicomponent flow and transport models for Nuclear Test-Ban Treaty monitoring and nuclear waste disposal applications

    Science.gov (United States)

    Jordan, Amy

    Open challenges remain in using numerical models of subsurface flow and transport systems to make useful predictions related to nuclear waste storage and nonproliferation. The work presented here addresses the sensitivity of model results to unknown parameters, states, and processes, particularly uncertainties related to incorporating previously unrepresented processes (e.g., explosion-induced fracturing, hydrous mineral dehydration) into a subsurface flow and transport numerical simulator. The Finite Element Heat and Mass (FEHM) transfer code is used for all numerical models in this research. An experimental campaign intended to validate the predictive capability of numerical models that include the strongly coupled thermal, hydrological, and chemical processes in bedded salt is also presented. Underground nuclear explosions (UNEs) produce radionuclide gases that may seep to the surface over weeks to months. The estimated timing of gas arrival at the surface may be used to deploy personnel and equipment to the site of a suspected UNE, if allowed under the terms of the Comprehensive Nuclear Test-Ban Treaty. A model was developed using FEHM that considers barometrically pumped gas transport through a simplified fractured medium and was used to quantify the impact of uncertainties in hydrologic parameters (fracture aperture, matrix permeability, porosity, and saturation) and season of detonation on the timing of gas breakthrough. Numerical sensitivity analyses were performed for the case of a 1 kt UNE at a 400 m burial depth. Gas arrival time was found to be most affected by matrix permeability and fracture aperture. Gases having higher diffusivity were more sensitive to uncertainty in the rock properties. The effect of seasonality in the barometric pressure forcing was found to be important, with detonations in March the least likely to be detectable based on barometric data for Rainier Mesa, Nevada. Monte Carlo modeling was also used to predict the window of

    A resolution calling for a ban on genetic engineering of human reproductive cells has been signed by leaders of almost every major church group in the United States. Some of the religious leaders, while not certain that a total moratorium should be placed on altering germline cells, signed the statement in order to stimulate public debate on the issue. Legislation has recently been introduced in Congress to set up a committee to monitor genetic engineering and its human applications, but author Jeremy Rifkin, the impetus behind the church leaders' resolution, argues that such tampering threatens the gene pool and should be banned altogether.

    The Great Belt Sonar (GBS) is a multi-functional sub-bottom profiling and buried object detection sonar system that can provide a wide variety of selectable operations based on user needs and environmental characteristics. In order to assess the bottom penetration and pipe tracking performance of the sonar system, controlled laboratory tests with known environmental parameters are required. Once the general characteristic and the potential for pipe detection of the system under the laboratory environment are established, field tests can be carried out to fully exercise all the system operations under the real ocean environment. Theoretical small scale system test considerations and a system setup for proof-of-concept trials have been proposed in `Pipe Tracking Sonar`, technical report. This report describes recent testing of the GBS system under small scale controlled laboratory environment. The experiment objectives given the size limitations of the laboratory environment, and the test equipment configuration and setup are described. The GBS system test measurements and findings are given. Finally, conclusions and future design and test considerations are discussed. The report assumes familiarity with the GBS system specifications and operational characteristics as well as theoretical background on acoustic propagation through the water-bottom interface. (EG)

    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.

    Monitoring atmospheric concentrations of radioxenons is relevant to provide evidence of atmospheric or underground nuclear weapon tests. However, when the design of the International Monitoring Network (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) was set up, the impact of industrial releases was not perceived. It is now well known that industrial radioxenon signature can interfere with that of nuclear tests. Therefore, there is a crucial need to characterize atmospheric distributions of radioxenons from industrial sources—the so-called atmospheric background—in the frame of the CTBT. Two years of Xe-133 atmospheric background have been simulated using 2013 and 2014 meteorological data together with the most comprehensive emission inventory of radiopharmaceutical facilities and nuclear power plants to date. Annual average simulated activity concentrations vary from 0.01 mBq/m3 up to above 5 mBq/m3 nearby major sources. Average measured and simulated concentrations agree on most of the IMS stations, which indicates that the main sources during the time frame are properly captured. Xe-133 atmospheric background simulated at IMS stations turn out to be a complex combination of sources. Stations most impacted are in Europe and North America and can potentially detect Xe-133 every day. Predicted occurrences of detections of atmospheric Xe-133 show seasonal variations, more accentuated in the Northern Hemisphere, where the maximum occurs in winter. To our knowledge, this study presents the first global maps of Xe-133 atmospheric background from industrial sources based on two years of simulation and is a first attempt to analyze its composition in terms of origin at IMS stations.

    There are numerous scientific applications of InSAR methods in tectonics, earthquake analysis and other geologic and geophysical fields. Ground motion on local and regional scale measured and monitored via the application of the InSAR techniques provide scientists and engineers with plenty of new insights and further understanding of subsurface processes. However, the operational use of InSAR is not yet very widespread. To foster the operational utilization of the Copernicus Sentinel Satellites in the day-to-day business of federal, state and municipal work and planning BGR (Federal Institute for Geosciences and Natural Resources) initiated workshops with potential user groups. Through extensive reconcilement of interests and demands with scientific, technical, economic and governmental stakeholders (e.g. Ministries, Mining Authorities, Geological Surveys, Geodetic Surveys and Environmental Agencies on federal and state level, SMEs, German Aerospace Center) BGR developed the concept of the InSAR based German National Ground Motion Service. One important backbone for the nationwide ground motion service is the so-called Persistent Scatterer Interferometry Wide Area Product (WAP) approach developed with grants of European research funds. The presentation shows the implementation of the ground motion service and examples for product developments for operational supervision of mining, water resources management and spatial planning. Furthermore the contributions of Copernicus Sentinel 1 radar data in the context of CTBT are discussed. The DInSAR processing of Sentinel 1 IW (Interferometric Wide Swath) SAR acquisitions from January 1st and 13th Jan. 2016 allow for the first time a near real time ground motion measurement of the North Korean nuclear test site. The measured ground displacements show a strong spatio-temporal correlation to the calculated epicenter measured by teleseismic stations. We are convinced this way another space technique will soon contribute even

    STORM is a recently developed super-resolution microscopy technique with up to 10 times better resolution than standard fluorescence microscopy techniques. However, as the image is acquired in a very different way than normal, by building up an image molecule-by-molecule, there are some significant challenges for users in trying to optimize their image acquisition. In order to aid this process and gain more insight into how STORM works we present the preparation of 3 test samples and the methodology of acquiring and processing STORM super-resolution images with typical resolutions of between 30-50 nm. By combining the test samples with the use of the freely available rainSTORM processing software it is possible to obtain a great deal of information about image quality and resolution. Using these metrics it is then possible to optimize the imaging procedure from the optics, to sample preparation, dye choice, buffer conditions, and image acquisition settings. We also show examples of some common problems that result in poor image quality, such as lateral drift, where the sample moves during image acquisition and density related problems resulting in the 'mislocalization' phenomenon.

    The Comprehensive Test Ban Treaty (CTBT) has been signed by many countries, including the US. The US Senate will start discussions of CTBT ratification in the near future. The Treaty aims to prevent any nuclear explosion from being conducted. A verification system is being implemented. It includes the possibility of On-Site Inspections (OSI) in a country where a suspicious seismic signal has been identified, which could come from a clandestine nuclear test. As part of an OSI, the use of drilling is allowed by the CTBT so as to obtain irrefutable proof of a Treaty violation. Such proof could be in the form of diagnostics of very high gamma radiation levels and high temperatures underground, which could not be explained by a natural source. A typical situation is shown in Figure 1, where the OSI team must find a nuclear cavity underground when only an approximate location is inferred. This calls for the ability to do directional drilling. Because there is no need for large borings and to minimize the cost and size of the equipment, slim-hole drilling is adequate. On that basis, an initial study by Lawrence Livermore National Laboratory[1] concluded that coiled-tubing (C-T) was the most attractive option for OSI drilling (Figure 2). Then, a preliminary design of a C-T Rapid Deployment Drilling System (RDDS) was performed by Maurer Engineering of Houston, TX[2]. Although a drilling mud system is also included in the RDDS definition, the preferred mode of operation of the RDDS would be drilling with air and foam. This minimizes water requirements in cases when water may be scarce at the OSI site. It makes the required equipment smaller than when a mud system is included. And it may increase the drilling rates, by eliminating the ''chip hold-down'' effect of a mud column. Following this preliminary design study, it was determined that the preferred bottom-hole assembly for such a system would be the Viper system of Schlumberger Anadrill, with one essential modification

    This crescent view of Earth's Moon in infrared wavelengths comes from a camera test by NASA's Mars Reconnaissance Orbiter spacecraft on its way to Mars. The mission's High Resolution Imaging Science Experiment camera took the image on Sept. 8, 2005, while at a distance of about 10 million kilometers (6 million miles) from the Moon. The dark feature on the right is Mare Crisium. From that distance, the Moon would appear as a star-like point of light to the unaided eye. The test verified the camera's focusing capability and provided an opportunity for calibration. The spacecraft's Context Camera and Optical Navigation Camera also performed as expected during the test. The Mars Reconnaissance Orbiter, launched on Aug. 12, 2005, is on course to reach Mars on March 10, 2006. After gradually adjusting the shape of its orbit for half a year, it will begin its primary science phase in November 2006. From the mission's planned science orbit about 300 kilometers (186 miles) above the surface of Mars, the high resolution camera will be able to discern features as small as one meter or yard across.

    This article analyses the possible reasons that have led the US Senate to reject the treaty of comprehensive nuclear test ban. Even if this decision did not retained the attention of the international public opinion, it appears as surprising because the USA have worked a lot for the elaboration of this treaty and were considered as the main beneficiaries of it. Three interpretations are proposed by the author: some purely internal disputes inside Clinton's administration, a real will of the USA to abandon the arms control policy, or an intermediate attitude which allows the USA to act on different levels and to get rid of common rules.

    The Acuityscope projects an image of a three bar resolution test target onto the patient's retina, where it is viewed and read by an observer. The test target consists of a series of three bar targets varying in size on a logarithmic scale. Individual targets are identified in the projected image by Bailey-Lovie log visual acuity equivalents. The projected image includes only those target sizes which are useful for estimating visual acuity. The Acuityscope is used for assessing the quality of retinal image formation, and is thus able to differentiate between poor visual acuity due to image degradation, (e.g. cataract or corneal disease) and poor visual acuity due to image handling defects (e.g. retinal or optic nerve disease). The use of the instrument is relevant to both clinical situations (e.g. pre-operative assessment of opacification of optical media) and experimental situations (e.g. clinical trials).

    The design concept and results of feasibility tests for a vertex detector intended for use in the TPC-PEP4/9 experiment are presented. The detector is based on a slow radial drift in dimethyl ether. High resolution localization of the avalanches at the sense wire is accomplished with nearby pickup wires and the utilization of waveform sampling electronics. The avalanche angular coordinate measurements, combined with knowledge of the electric field distribution and drift velocity permit reconstruction of the trajectory using essentially all track information. Measurements with a test chamber constructed to study characteristics of avalanche localization indicate that the recoverable track information in one centimeter of dimethyl ether at 1.5 atm is equivalent to 30 measurements of 40 μm accuracy.

    temporal auditory processing is defined as the perception of sound or of sound alteration within a restricted time interval and is considered a fundamental ability for the auditory perception of verbal and non verbal sounds, for the perception of music, rhythm, periodicity and in the discrimination of pitch, duration and of phonemes. to compare the performance of normal Brazilian adults in two temporal resolution tests: the Gaps-in-Noise Test (GIN) and the Random Gap Detection Test (RGDT), and to analyze potential differences of performance in these two tests. twenty-five college students with normal hearing (11 males and 14 females) and no history of educational, neurological and/or language problems, underwent the GIN and RGDT at 40dB SL. statistically significant gender effects for both tests were found, with female participants showing poorer performance on both temporal processing tests. In addition, a comparative analysis of the results obtained in the GIN and RGDT revealed significant differences in the threshold measures derived for these two tests. In general, significantly better gap detection thresholds were observed for both male and female participants on the GIN test when compared to the results obtained for the RGDT. male participants presented better performances on both RGDT and GIN, when compared to the females. There were no differences in performance between right and left ears on the GIN test. Participants of the present investigation, males and females, performed better on the GIN when compared to the RGDT. The GIN presented advantages over the RGDT, not only in terms of clinical validity and sensibility, but also in terms of application and scoring.

  14. Thoughts on Book Banning

    Full Text Available This article, written by the author who used to be one of the former ministers of national education, includes some instances that took place in different date ranges in Turkey and different countries around the world about book censorship. It is emphasized in the article that censorship has been in public agenda since history of religions, some books with various subjects in different periods has been censored especially due to public safety and decency. The author states that philosophers particularly such as authors, publishers, journalists and scientists have been suppressed in each period by indicating that censorship is mainly derived from differences of ideas and the root of the problem is violation of freedom of thought and thought broadcast. The article supports the idea that book censorship is against democracy by citing quotations from famous statesmen, scientists, lawyers and litterateurs from past to present. Suggestions were made for governments about subjects such as freedom of thought and freedom of press which are the basis of democracy by referring to the “banned books week” as an example from the USA. It is suggested that such practices should be initiated in Turkey as well on the path towards the solution of the problem.

    Test-retest variability (TRV) of visual field (VF) data seriously degrades our capacity to recognize true VF progression. We conducted repeated high-resolution perimetry with a test interval of 0.5° to investigate the sources of TRV. In particular, we examined whether the spatial variance of the observed sensitivity changes or if their absolute magnitude was of more importance. Sixteen eyes of 16 glaucoma patients were each tested three times at 61 VF locations along the superior-temporal 45° meridian using a modified protocol of the Octopus 900 perimeter. TRV was quantified as the standard deviation of the repeats at each point (retest-SD). We also computed the mean sensitivity at each point (retest-MS) and the running spatial-SD along the tested meridian. Multiple regression models investigated whether any of those variables (and also age, sex, and VF eccentricity) were significant independent determinants of TRV. The main independent determinants of TRV were the retest-MS at -0.04 dB TRV/dB loss ( P retest-SD at 0.47 dB spatial variance/dB loss ( P < 0.0001, t -statistic 12.5). The larger effect for the spatial-SD suggested that it was perhaps a stronger determinant of TRV than scotoma depth per se. This might support the hypothesis that interactions between small perimetric stimuli, rapidly varying sensitivity across the field, and normal fixational jitter are strong determinants of TRV. Our study indicates that methods that might reduce the effects of jagged sensitivity changes, such as increasing stimulus size or better gaze tracking, could reduce TRV.

    International Nuclear Information System (INIS)

    Hassard, J.

    1992-01-01

    A critique of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is presented. While five nations known to have openly tested nuclear weapons (the United States, Britain, France, the Soviet Union and India) have agreed, at least at present, to observe a moritorium on testing nuclear weapons, only China dissenting, there are many other ''threshold'' nations interested in nuclear weapons, but not bound by Treaty restrictions. Double standards by the NPT nations do nothing to encourage threshold nations to hold back their nuclear programs. The threshold nations, including Iran, Iraq, Israel, Libya, Syria, Pakistan, India, Brazil, Argentina, South Africa, Algeria, North Korea and the Ukraine and Kazakhstan, four Soviet Republics, have been stockpiling weapons material or reactor technology and many see themselves as threatened by traditional political opponents. The author urges conformity to Rajv Gandhi's the former Indian prime minister, three-stage set of proposals aimed at producing a worldwide end to nuclear proliferation. (UK)

    This paper describes the research on the energy and position resolution of the MWPC used in the e/π Test Beam on BEPC (Beijing Electron Positron Collider), which localizes the particles of e/π by the readout method of gravity center of the induced charges on the cathode strips. The spatial resolution of about 0.24 mm and energy resolution of 17% for 5.9 keV γ photons are attained at the 3700 V anode voltage. For the 1.1 GeV electrons, the spatial resolution of 0.3 mm is obtained. The contributions of various factors to energy resolution are analysed. It is found that energy resolution is changed with the anode voltage and there exists a least energy resolution. The reasons for these are discussed. (authors)

    This article argues that now that the East-West conflict is over, nuclear-powered vessels should be retired. Nuclear-powered ships and submarines lack military missions, are expensive to build and operate, generate large amounts of long-lived deadly nuclear waste from their normal operations and when they are decommissioned, and are subject to accidents or deliberate attack which can result in the sinking of nuclear reactors and the release of radiation. With the costs of nuclear-powered vessels mounting, the time has come to ban nuclear power at sea. (author)

  3. The Impact of Banning Juvenile Gun Possession.

    OpenAIRE

    A 1994 federal law bans possession of handguns by persons under 18 years of age. Also in 1994, 11 states passed their own juvenile gun possession bans. Eighteen states had previously passed bans, 15 of them between 1975 and 1993. These laws were intended to reduce homicides, but arguments can be made that they have no effect on or that they even increase the homicide rate. This paper estimates the laws' impacts on various crime measures, primarily juvenile gun homicide victimizations and suic...

    Aji, RNB; Artono; Liana, C.

    2018-01-01

    The prohibition of books conducted by the government through its apparatus without any due process of law is unfortunate. The Constitutional Court of the Republic of Indonesia (MKRI) in 2010 was decided that book banning is contradictory to the 1945 Constitution (UUD 1945). The purpose of this paper is to know Indonesia, according to the Constitutional Court must absolutely carry out the function of due process of law that is law enforcement in a judicial system when it wants to prohibit printed material which is a book, whether it is a book that is considered criticism and books that teach radicalism. It would be wise for anyone who disagrees with a book, and then responds by writing through a book. The result of this article is to support and suggest that the government and its apparatus in the state of the law should not arbitrarily impose a book ban. Likewise, people should not take violence action to respond this issue. In historical records, the prohibition of books without due process of law is always followed by the withdrawal of books and make people unable to deal with differences, especially in knowledge. That’s why, the government and its apparatus must create a conducive situation and support the creation of various perspectives in the framework of the progress of science through a book. It would implicate that people can respect in any perspective and thought.

  12. Experimental economics' inconsistent ban on deception.

    Science.gov (United States)

    Hersch, Gil

    2015-08-01

    According to what I call the 'argument from public bads', if a researcher deceived subjects in the past, there is a chance that subjects will discount the information that a subsequent researcher provides, thus compromising the validity of the subsequent researcher's experiment. While this argument is taken to justify an existing informal ban on explicit deception in experimental economics, it can also apply to implicit deception, yet implicit deception is not banned and is sometimes used in experimental economics. Thus, experimental economists are being inconsistent when they appeal to the argument from public bads to justify banning explicit deception but not implicit deception. Copyright © 2015 Elsevier Ltd.

    To examine youth exposure to smoking in cars following 7 provincial bans on smoking in cars with children in Canada. Repeated cross-sectional data from the 2004-2012 Youth Smoking Survey (n=91,800) were examined. Using a quasi-experimental design, contrasts of the interaction of survey year and province included in the logistic regression analyses were used to test whether exposure significantly declined pre-post implementation of a ban on smoking in cars relative to control provinces not implementing a ban. Exposure across all provinces declined from 26.5% in 2004 to 18.2% of youth in 2012. Exposure declined significantly from pre to post implementation of a ban on smoking in cars with children in Ontario at time 1 post ban (Pre-Ban=20.4% T1post=10.3%, OR=0.45), time 2 post ban (12.1%, OR=0.61) and time 3 post ban (11.6%, OR=0.58) relative to control provinces that did not implement a ban. In British Columbia exposure to smoking in cars declined significantly at pre-post ban time 3 compared to the control group (Pre-Ban=21.2%, T3post=9.6%, OR=0.51). No other provinces had a significant change in exposure pre-post ban relative to the control provinces. Although rates declined, significant differences were only found in Ontario relative to control provinces in the immediate and long term. Copyright © 2015 Elsevier Inc. All rights reserved.

    (1) BACKGROUND: The home environment is a major source of Environmental Tobacco Smoke (ETS) exposure among children especially in early childhood. ETS exposure is an important health risk among children and can cause severe and chronic diseases, such as asthma, bronchitis, and premature death. However, ETS exposure at home has often been neglected in the Chinese families. Identification of factors that facilitate or otherwise hamper the adoption of home smoking ban will help in the design and implementation of evidence-based intervention programs. This study identifies factors correlated with home smoking bans in Chinese families with children. (2) METHODS: A cross-sectional survey of parents living in Nanning city, Guangxi Province, China with at least one smoker and a child in the household was conducted between September, 2013 and January, 2014. A Chi-square test was used to compare categorical variables differences between the parents who had home smoking bans and those with no home smoking ban. Multiple logistic regression analyses were used to identify factors correlated with home smoking bans. (3) RESULTS: 969 completed questionnaires were collected with a response rate of 92.29% (969/1050). Of the respondents (n = 969), 14.34% had complete home smoking bans. Factors that were associated with home smoking bans were: having no other smokers in the family (OR = 2.173), attaining education up to high school (OR = 2.471), believing that paternal smoking would increase the risk of lower respiratory tract illnesses (OR = 2.755), perceiving the fact that smoking cigarettes in the presence of the child will hurt the child's health (OR = 1.547), believing that adopting a no smoking policy at home is very important (OR = 2.816), and being confident to prevent others to smoke at home (OR = 1.950). Additionally, parents who perceived difficulty in adopting a no smoking policy at home would not have a home smoking ban (OR = 0.523). (4) CONCLUSIONS: A home smoking ban is

  7. Trans fat bans and human freedom.

    Science.gov (United States)

    Resnik, David

    2010-03-01

    A growing body of evidence has linked consumption of trans fatty acids to cardiovascular disease. To promote public health, numerous state and local governments in the United States have banned the use of artificial trans fats in restaurant foods, and additional bans may follow. Although these policies may have a positive impact on human health, they open the door to excessive government control over food, which could restrict dietary choices, interfere with cultural, ethnic, and religious traditions, and exacerbate socioeconomic inequalities. These slippery slope concerns cannot be dismissed as far-fetched, because the social and political pressures are place to induce additional food regulations.

    A growing body of evidence has linked consumption of trans fatty acids to cardiovascular disease. To promote public health, numerous state and local governments in the United States have banned the use of artificial trans fats in restaurant foods, and additional bans may follow. Although these policies may have a positive impact on human health, they open the door to excessive government control over food, which could restrict dietary choices, interfere with cultural, ethnic, and religious traditions, and exacerbate socioeconomic inequalities. These slippery slope concerns cannot be dismissed as far-fetched, because the social and political pressures are place to induce additional food regulations. To protect human freedom and other values, policies that significantly restrict food choices, such as bans on types of food, should be adopted only when they are supported by substantial scientific evidence, and when policies that impose fewer restrictions on freedom, such as educational campaigns and product labeling, are likely to be ineffective.

    Lamb wave testing is promising for damage detection and evaluation in large-area structures. The dispersion of Lamb waves is often unavoidable, restricting testing resolution and making the signal hard to interpret. A smoothed Capon algorithm is proposed in this paper to estimate the accurate path length of each wave packet. In the algorithm, frequency domain whitening is firstly used to obtain the transfer function in the bandwidth of the excitation pulse. Subsequently, wavenumber domain smoothing is employed to reduce the correlation between wave packets. Finally, the path lengths are determined by distance domain searching based on the Capon algorithm. Simulations are applied to optimize the number of smoothing times. Experiments are performed on an aluminum plate consisting of two simulated defects. The results demonstrate that spatial resolution is improved significantly by the proposed algorithm.

    2001-01-01

    For the second time the European Commission has postponed the sales ban on cosmetics products that have been developed and tested in animal experiments now until 2002. In the meantime the Commission wants to adopt the Seventh Amendment of the EU Cosmetics Directive. In its draft the Commission proposes to scrap the sales ban and replace it with an animal testing ban. This change would avoid possible conflicts with the WTO, however, from the animal welfare point of view would result in animal testing moving into third countries instead of avoiding them. This is because cosmetics products tested on animals outside the EU could be sold in the EU without any restrictions. As a consequence this measure would take the pressure from authorities and industry to further develop and adopt alternative methods. Other proposed measures are not acceptable from the animal welfare point of view, e.g. because they contradict Directive 86/609 and would result in a delay of the application of validated alternative methods. The Deutscher Tierschutzbund therefore still demands an immediate and complete sales ban in connection with an animal testing ban within the EU.

    2016-01-01

    Super-resolution optical fluctuation imaging (SOFI) allows one to perform sub-diffraction fluorescence microscopy of living cells. By analyzing the acquired image sequence with an advanced correlation method, i.e. a high-order cross-cumulant analysis, super-resolution in all three spatial dimensions can be achieved. Here we introduce a software tool for a simple qualitative comparison of SOFI images under simulated conditions considering parameters of the microscope setup and essential properties of the biological sample. This tool incorporates SOFI and STORM algorithms, displays and describes the SOFI image processing steps in a tutorial-like fashion. Fast testing of various parameters simplifies the parameter optimization prior to experimental work. The performance of the simulation tool is demonstrated by comparing simulated results with experimentally acquired data.

  17. Resolution improvement of ultrasonic echography methods in non destructive testing by adaptative deconvolution

    1989-01-01

    The ultrasonic echography has a lot of advantages which make it attractive for nondestructive testing. But the important acoustic energy useful to go through very attenuating materials can be got only with resonant translators, that is a limit for the resolution on measured echograms. This resolution can be improved by deconvolution. But this method is a problem for austenitic steel. Here is developed a method of time deconvolution which allows to take in account the characteristics of the wave. A first step of phase correction and a second step of spectral equalization which gives back the spectral contents of ideal reflectivity. The two steps use fast Kalman filters which reduce the cost of the method

    The Italian smoking ban entered into force on January 10th, 2005, and banned smoking from enclosed workplaces and hospitality premises (HPs), even though provided separated smoking areas. Actually, only 1-2%of HPs built these areas, while no figures are available on the prevalence of smoking rooms in workplaces other than HPs. Italians were more in favour of the law after the ban. In 2008 Italians were the Europeans most in favour of a national smoking ban (88%). Measurements of environmental nicotine and particulate matter with a diameter hospitality sector against the ban in 2004, no studies on impact of the ban on hospitality industry businesses were conducted in Italy. We used the conceptual model for the evaluation of the impact of smoke-free policies, proposed by the International Agency for Research on Cancer (IARC), to compare Italian and Scottish evaluations of the bans. The Scottish evaluation was planned some years before the implementation, and was based on a network of researchers of different disciplines. The quantification of decrease in second-hand smoke (SHS) exposure in the general population and in hospitality workers was one of the main objectives of the Scottish evaluation. The Italian evaluation devoted more attention to distal (reduction of hospital admissions) and incidental effects of the law (trend in smoking prevalence, cigarette consumption). Qualitative studies in bars, homes, and communities recording changes in attitudes on tobacco smoking after the introduction of the ban, were conducted only in Scotland. In Italy the main problem was to develop and fund a network of researchers involved on a shared evaluation plan.

    This study was undertaken to determine prevalence, extent, and severity of focal airtrapping at expiratory high-resolution CT, and to compare focal airtrapping with age, gender, pulmonary function tests, and blood gas analysis. Two-hundred seventeen patients with and without pulmonary disease underwent paired inspiratory/expiratory high-resolution CT. Six scan pairs with corresponding scan levels were visually assessed for focal - not diffuse - airtrapping using a four-point scale. Pulmonary function tests and blood gas analysis were available for correlation in all patients (mean interval 5 days). Focal airtrapping with lower lung predominance was observed in 80 % of patients. Twenty-six of 26 patients with restrictive lung function impairment exhibited focal airtrapping (mean score 2.4), whereas only 72 of 98 (74 %) patients with obstruction did (mean score 1.5; p < 0.05). Fifty-eight of 70 (83 %) patients with normal lung function (mean score 1.8) and 19 of 23 (83 %) patients with mixed impairment (mean score 1.8) had focal airtrapping. Focal airtrapping showed negative correlations with static lung volumes (-0.27 to -0.37; p < 0.001) in all patients and moderate positive correlations with dynamic parameters (0.3-0.4; p < 0.001) in patients with obstruction. No significant correlations were found with age, gender, and blood gas analysis. Visual assessment of focal - not diffuse - airtrapping at expiratory high-resolution CT does not correlate with physiological evidence of obstruction as derived from pulmonary function tests since the perception of focal airtrapping requires an adequate expiratory increase in lung density.

    2010-01-01

    Purpose To quantify the difference between recognition (letter) and resolution (Landolt) visual acuity (VA) in a group of normally sighted subjects. Is it reasonable to assume that the two acuity measures are clinically equivalent? Methods A pair of 6 m acuity test charts was produced: one comprised letters and the other Landolt broken rings. Construction of both charts conformed to the logMAR design format. Monocular VA was determined for the dominant eye of 300 screened and normally sighted optometric patients aged 16 to 40, each wearing an optical refractive (spectacle) correction. Results Letter acuity was superior to Landolt acuity (P≤0.0001). The mean paired acuity difference was -0.041 logMAR (standard deviation 0.034): the 95% limits of agreement were ±0.067 logMAR units or ±3.3 chart optotype. Repeatability was high and similar for each chart type (±2.1 and ±2.4 optotype for letter and Landolt, respectively). Gender, test sequence, and laterality of the dominant eye (left or right) were each non-statistically significant variables. Conclusions For normally sighted subjects wearing an optimal refractive correction, a bias was recorded in favour of recognition over resolution acuity: the clinical difference amounted to approximately 40% of one logMAR chart line, with similar high repeatability for either chart optotype. We conclude that the assumption of clinical equivalence between letter and Landolt acuity is reasonable under optimum test conditions.

    Optical coherence tomography (OCT) systems are becoming more commonly used in biomedical imaging and, to enable continued uptake, a reliable method of characterizing their performance and validating their operation is required. This paper outlines the use of femtosecond laser subsurface micro-inscription techniques to fabricate an OCT test artifact for validating the resolution performance of a commercial OCT system. The key advantage of this approach is that by utilizing the nonlinear absorption a three dimensional grid of highly localized point and line defects can be written in clear fused silica substrates.

    Full Text Available Objectives: This research was undertaken with the aim of assessing the indoor air quality in popular hospitality venues, as also to evaluate the effectiveness of the nationwide comprehensive public smoking ban. The analysis was split into two halves - baseline study taken up prior to implementation of the said ban on 2 nd October 2008, and the follow-up study after it came into effect. Materials and Methods: Twenty-five venues including five restaurants, fourteen resto-bars, two hookah (smoking water-pipe cafes and four pubs were selected using a mix of random, convenience and purposeful sampling. Particulate matter (PM 2.5 measurements at these venues were made using TSI SidePak AM510 Personal Aerosol Monitor. Results: The average PM 2.5 level in venues where smoking was permitted prior to implementation of ban was found to be 669.95 ΅g/m 3 in the baseline study. Post ban, the average PM 2.5 level in same test venues reduced to 240.8 ΅g/m 3 . The hookah cafes were an exception as the average PM 2.5 levels exceeded the permissible limits before as well as post ban. Conclusion: The baseline study showed that the hospitality venues had hazardous levels of PM 2.5 particles arising from second-hand smoke prior to smoking ban. These decreased by a maximum of 64% after the law took effect. A substantial improvement in air quality at these venues post implementation of the smoking ban indicated the effectiveness of the law.

  7. Resolution enhancement for ultrasonic echographic technique in non destructive testing with an adaptive deconvolution method

    International Nuclear Information System (INIS)

    Vivet, L.

    1989-01-01

    The ultrasonic echographic technique has specific advantages which makes it essential in a lot of Non Destructive Testing (NDT) investigations. However, the high acoustic power necessary to propagate through highly attenuating media can only be transmitted by resonant transducers, which induces severe limitations of the resolution on the received echograms. This resolution may be improved with deconvolution methods. But one-dimensional deconvolution methods come up against problems in non destructive testing when the investigated medium is highly anisotropic and inhomogeneous (i.e. austenitic steel). Numerous deconvolution techniques are well documented in the NDT literature. But they often come from other application fields (biomedical engineering, geophysics) and we show they do not apply well to specific NDT problems: frequency-dependent attenuation and non-minimum phase of the emitted wavelet. We therefore introduce a new time-domain approach which takes into account the wavelet features. Our method solves the deconvolution problem as an estimation one and is performed in two steps: (i) A phase correction step which takes into account the phase of the wavelet and estimates a phase-corrected echogram. The phase of the wavelet is only due to the transducer and is assumed time-invariant during the propagation. (ii) A band equalization step which restores the spectral content of the ideal reflectivity. The two steps of the method are performed using fast Kalman filters which allow a significant reduction of the computational effort. Synthetic and actual results are given to prove that this is a good approach for resolution improvement in attenuating media [fr

    2012-05-01

    The Irish workplace smoking ban has been described as possibly a tipping point for public health worldwide. This article presents the first analysis of the newspaper coverage of the ban over the duration of the policy formation process. It adds to previous studies by analyzing how health communication strategists engaged, over time, with a newsworthy topic, viewed as being culturally controversial. It analyzes a sample of media content (n = 1,154) and firsthand accounts from pro-ban campaigners and journalists (n = 10). The analysis shows that the ban was covered not primarily as a health issue: Economic, political, social, democratic, and technical aspects also received significant attention. It shows how coverage followed controversy and examines how pro-ban campaigners countered effectively the anti-ban communication efforts of influential social actors in the economic and political spheres. The analysis demonstrates that medical-political sources successfully defined the ban's issues as centrally concerned with public health.

    As millions of immigrants moved to Hong Kong (HK) from China in the recent decades, large amount of residential housings were built in the early years and a substantial proportion of those buildings used asbestos-containing materials (ACMs). Since the number of new cases of ARDs diagnosed has increased year by year since 1990’s, the remarkable increase of incidences had drawn the attention of the public and most importantly the HK government. It became one of the trigger points leading to asbestos ban in HK history. Comparatively, non-governmental organizations (NGOs), labor unions and patients’ self-help organizations demonstrated a more aggressive and proactive attitude than the HK government and have played a key role in the development of asbestos banning policy in HK. After numerous petitions and meetings with the government representatives by those parties in the past decade, the HK government eventually changed its attitude and started to consider terminating the endless threat from asbestos by amending the policy, and the new clause of legislation for banning of all forms of asbestos was enacted on 4 April 2014. Other than the restriction of asbestos use, the compensation system about ARDs has also made some great moves by the effort of those parties as well. Based on the experience we learnt through the years, efforts from different stakeholders including patients’ self-help organizations, NGOs, legislative councilors, and media power are absolutely essential to the success of progression and development in today’s asbestos banning in HK.

    Admitting banking in emissions trading systems reduces overall compliance costs by allowing for inter-temporal flexibility: cost savings can be traded over time. However, unless individual EU Member States (MS) decide differently, the transfer of unused allowances from the period of 2005-2007 into the first commitment period under the Kyoto Protocol, i.e. 2008-2012, will be prohibited. In this paper, we first explore the implications of such a ban on banking when initial emission targets are lenient. This analysis is based on a simulation which was recently carried out in Germany with companies and with a student control group. The findings suggest that a EU-wide ban on banking would lead to efficiency losses in addition to those losses which arise from the lack of inter-temporal flexibility. Second, we use simple game-theoretic considerations to argue that, under reasonable assumptions, such a EU-wide ban on banking will be the equilibrium outcome. Thus, to avoid a possible prisoners' dilemma, MS should have co-ordinated their banking decisions

    Full Text Available This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke and respiratory (chronic obstructive pulmonary disease and asthma conditions were examined before and after the smoking ban.Crude annual and monthly admission rates for the above conditions were calculated from April 1, 1995 to December 31, 2008 in all PEI acute care hospitals. Autoregressive Integrated Moving Average time series models were used to test for changes in mean and trend of monthly admission rates for study conditions, control conditions and a control province after the comprehensive smoking ban. Age- and sex-based analyses were completed.The mean rate of acute myocardial infarctions was reduced by 5.92 cases per 100,000 person-months (P = 0.04 immediately after the smoking ban. The trend of monthly angina admissions in men was reduced by -0.44 cases per 100,000 person-months (P = 0.01 in the 67 months after the smoking ban. All other cardiovascular and respiratory admission changes were non-significant.A comprehensive smoking ban in PEI reduced the overall mean number of acute myocardial infarction admissions and the trend of angina hospital admissions.

  15. An Efficient Implementation of Fixed Failure-Rate Ratio Test for GNSS Ambiguity Resolution.

    Hou, Yanqing; Verhagen, Sandra; Wu, Jie

    2016-06-23

    Ambiguity Resolution (AR) plays a vital role in precise GNSS positioning. Correctly-fixed integer ambiguities can significantly improve the positioning solution, while incorrectly-fixed integer ambiguities can bring large positioning errors and, therefore, should be avoided. The ratio test is an extensively used test to validate the fixed integer ambiguities. To choose proper critical values of the ratio test, the Fixed Failure-rate Ratio Test (FFRT) has been proposed, which generates critical values according to user-defined tolerable failure rates. This contribution provides easy-to-implement fitting functions to calculate the critical values. With a massive Monte Carlo simulation, the functions for many different tolerable failure rates are provided, which enriches the choices of critical values for users. Moreover, the fitting functions for the fix rate are also provided, which for the first time allows users to evaluate the conditional success rate, i.e., the success rate once the integer candidates are accepted by FFRT. The superiority of FFRT over the traditional ratio test regarding controlling the failure rate and preventing unnecessary false alarms is shown by a simulation and a real data experiment. In the real data experiment with a baseline of 182.7 km, FFRT achieved much higher fix rates (up to 30% higher) and the same level of positioning accuracy from fixed solutions as compared to the traditional critical value.

  16. Compliance and enforcement of a partial smoking ban in Lisbon taxis: an exploratory cross-sectional study

    Full Text Available Abstract Background Research evaluating enforcement and compliance with smoking partial bans is rather scarce, especially in countries with relative weak tobacco control policies, such as Portugal. There is also scarce evidence on specific high risk groups such as vehicle workers. In January 2008, Portugal implemented a partial ban, followed by poor enforcement. The purpose of this study was to explore the effectiveness of a partial smoking ban in a pro-smoking environment, specifically transportation by taxi in the city of Lisbon. Ban effectiveness was generally defined by ban awareness and support, compliance and enforcement. Methods Exploratory cross-sectional study; purposive sampling in selected Lisbon streets. Structured interviews were conducted by trained researchers while using taxi services (January 2009-December 2010. Participants: 250 taxi drivers (98.8% participation rate. Chi-square, McNemar, Man Whitney tests and multiple logistic regression were performed. Results Of the participants, 249 were male; median age was 53.0 years; 43.6% were current smokers. Most participants (82.8% approved comprehensive bans; 84.8% reported that clients still asked to smoke in their taxis; 16.8% allowed clients to smoke. Prior to the ban this value was 76.9% (p  Conclusions Despite the strong ban support observed, high smoking prevalence and poor enforcement contribute to low compliance. The findings also suggest low compliance among night-shift and vehicle workers. This study clearly demonstrates that a partial and poorly-enforced ban is vulnerable to breaches, and highlights the need for clear and strong policies.

    Rebourgeard, P.

    1991-01-01

    We present the design of a particle detector involving a coherent array of 100 000 plastic scintillating microfibers, with an individual core diameter around 50 micrometers, and an intensified bidimensional CCD array. We investigate both theoretically and experimentally the use of polystyrene based scintillators in optical multimodal fibers. The isotropic excitation of modes and the characteristics of energy transfers between the polystyrene matrix and the added fluorescent dyes are of particular interest. An experimental approach is proposed and applied to the development of a new binary scintillator. In order to study the transmission of the signal from the interaction area to the output face, we specify the loss factors, the resolution and the signal to noise ratio within the fiber array. The low light level at the output face of the detector leads us to use image intensifiers in photon counting mode. This requires a detailed analysis of resolutions, gain, noise and detectivity concepts. We propose to describe these strongly correlated notions by the moment generation formalism. Thus, a previous modelisation of the photoelectronic devices allows us to evaluate the performance of the readout chain. A complete detector has been assembled and tested on a high energy hadron beam; the measurements are in good agreement with the modelisation [fr

    Environmental legislation and proper implementation are critical in environmental protection. In the past, beehive coke ovens (BCOs) were popular in China, resulting in enormous emissions of benzo[ a ]pyrene (BaP), a common indicator of carcinogenic polycyclic aromatic hydrocarbons. BCOs were banned by the Coal Law in 1996. Although BCO numbers have declined since the ban, they were not eliminated until 2011 due to poor implementation. Here, we present the results of a quantitative evaluation of the health effects of historical BCO operation, the health benefits of the ban, and the adverse impacts of the poor implementation of the ban. With only limited official statistics available, historical and geospatial data about BCOs were reconstructed based on satellite images. Emission inventories of BaP from BCOs were compiled and used to model atmospheric transport, nonoccupational population exposure, and induced lung cancer risk. We demonstrated that more than 20% of the BaP in ambient air was from BCOs in the peak year. The cumulative nonoccupational excess lung cancer cases associated with BaP from BCOs was 3,500 (±1,500) from 1982 to 2015. If there was no ban, the cases would be as high as 9,290 (±4,300), indicating the significant health benefits of the Coal Law. On the other hand, if the ban had been fully implemented immediately after the law was enforced in 1996, the cumulative cases would be 1,500 (±620), showing the importance of implementing the law.

    2017-04-01

    Sintering in snow is very active due to a high homologous temperature and has a major effect on the evolution of the snow mechanical properties. We investigated the sintering rate of snow using high-resolution penetration tests performed with the Snow Micro Penetrometer (SMP) in a cold room at -10°C. To this end, we prepared several samples by sieving rounded grain snow with different sieve sizes (0.8, 1 and 1.6 mm) and conducted numerous SMP tests at different times during the first day of sintering. The SMP was modified such that only the measuring tip was in contact to the snow and we mounted three different tips with diameters of 4, 5 and 8 mm. The increase of the measured mean penetration resistance is shown to follow a power law whose exponent is defined as the sintering rate. The sintering rate mean value is about 0.25, which is consistent with values reported in the literature and it increases with specific surface area and depth. However, the sintering rate diminishes when SMP tip size increases, which is counterintuitive for a material property. An advanced analysis is thus required to extract relevant material properties, as the deflection at rupture, individual rupture force of bonds, and spatial intensity of rupture events, out of the SMP signal. A Poisson shot noise model [Löwe and Herwijnen 2012] was used, in which a depth-dependence of the parameters was assumed. The individual rupture force follows a power law with exponents around 0.3 with almost no dependency on the tip size. In comparison, the time evolution of intensity and deflection at rupture were negligible. This approach exploits the high-resolution of the SMP to give new insights on the sintering mechanisms in snow.

  1. Epistemic Dependence and the EU Seal Ban Debate

    Directory of Open Access Journals (Sweden)

    Lars Christian Blichner

    2015-03-01

    Full Text Available On September 2009 the European Union (EU adopted a regulation banning the import of seal products into the EU or placing seal products on the EU market. The European Parliament was the main driving force behind the regulation and the EU has been criticised by affected countries outside the EU for not basing this decision on the available expert knowledge. The questions asked are how, given epistemic dependence, non-experts may challenge an expert based policy proposal. Can non-experts hold experts accountable, and if so in what way? Three main tests and ten subtests of expert knowledge are proposed and these tests are then used to assess whether the European Parliament did in fact argue in a way consistent with available expert knowledge in amending the Commission proposal for a regulation.

    Northwest directed slip from the southern San Andreas Fault is transferred to the Mission Creek, Banning, and Garnet Hill fault strands in the northwestern Coachella Valley. How slip is partitioned between these three faults is critical to southern California seismic hazard estimates but is poorly understood. In this paper, we report the first slip rate measured for the Banning fault strand. We constrain the depositional age of an alluvial fan offset 25 ± 5 m from its source by the Banning strand to between 5.1 ± 0.4 ka (95% confidence interval (CI)) and 6.4 + 3.7/-2.1 ka (95% CI) using U-series dating of pedogenic carbonate clast coatings and 10Be cosmogenic nuclide exposure dating of surface clasts. We calculate a Holocene geologic slip rate for the Banning strand of 3.9 + 2.3/-1.6 mm/yr (median, 95% CI) to 4.9 + 1.0/-0.9 mm/yr (median, 95% CI). This rate represents only 25-35% of the total slip accommodated by this section of the southern San Andreas Fault, suggesting a model in which slip is less concentrated on the Banning strand than previously thought. In rejecting the possibility that the Banning strand is the dominant structure, our results highlight an even greater need for slip rate and paleoseismic measurements along faults in the northwestern Coachella Valley in order to test the validity of current earthquake hazard models. In addition, our comparison of ages measured with U-series and 10Be exposure dating demonstrates the importance of using multiple geochronometers when estimating the depositional age of alluvial landforms.

    Full Text Available The Securities and Exchange Commission’s 2008 emergency order introduced a shorting ban of some 800 financials traded in the US. This paper provides an empirical analysis of the options market around the ban period. Using transaction level data from OPRA (The Options Price Reporting Authority, we study the options volume, spreads, pricing measures and option trade volume informativeness during the ban. We also consider the put–call parity relationship. While mostly statistically significant, economic magnitudes of our results suggest that the impact of the ban on the equity options market was likely not as dramatic as initially thought.

    Comprehensive bans on tobacco advertising and promotion were introduced through tobacco control legislation in Viet Nam, but it has been established that violations of the bans are very common. This study was conducted to explore the trend in violations of bans on tobacco advertising and promotion at points of sale in Viet Nam in the past six years and to explore any differences in the violation situations before and after the Law on Tobacco Control came into effect on 1st May 2013. Quantitative data were collected through observation of violations of the bans on tobacco advertising and promotion at points of sale in 10 provinces throughout Viet Nam in four survey rounds (2009, 2010, 2011, and 2015). Variation in violation prevalence over time was examined by chi-square test using a Bonferini method. Binary logistic regression was employed to identify the factors that may have influences on different types of violation. A level of significance of padvertising increased while violations on promotion ban and on displaying tobacco decreased through time. Some factors associated with the tobacco advertising and promotion bans included surveyed years, types of points of sale, regions and areas where the points of sale were located. The enforcement of the bans did not improve even after the issuance and the enactment of the Law on Tobacco Control. This suggests that the monitoring and enforcement of bans on tobacco advertising and promotion at points of sale should be strengthened. Penalties should be strictly applied for violators as indicated in the current tobacco control legislation.

    Accurate identification of individuals with TB infection, is required to achieve the WHO's End TB Strategy goals. While there is general acceptance that the T-SPOT.TB test borderline category provides an opportunity to increase test resolution of results around the test cut-off point, this has not been investigated. 645,947 tests were analyzed to determine frequency of borderline results, effect of age and time between tests and associations between subjects' clinical risk factors and retest results. 645,947 tests produced 93.5% negatives, 4% positives, 0.6% invalids, and 1.8% borderlines. Within the borderline results, 5044 were repeated, with 59.2%, 20.0% and 20.2% resolving to negative, positive and borderline, respectively. Age of subject did not affect retest results; however, time between tests indicated that retest resolution occurred with greatest frequency after 90 days. TB risk factors were provided for 2640 subjects and 17% of low risk subjects with a high initial borderline resolved to negative while 27.6% of subjects with high risk and an initial low borderline resolved to positive, suggesting that these subjects could have been inappropriately classified if using a single cut-off point test with no borderline category. This study demonstrates the utility of the T-SPOT.TB test's borderline category to increase test resolution around the test cut-off point. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    2017-04-01

    Accurate estimation of precipitation is one of the most difficult and significant tasks in the area of weather diagnostic and forecasting. In the Korean Peninsula, heavy precipitations are caused by various physical mechanisms, which are affected by shortwave trough, quasi-stationary moisture convergence zone among varying air masses, and a direct/indirect effect of tropical cyclone. In addition to, various geographical and topographical elements make production of temporal and spatial distribution of precipitation is very complicated. Especially, localized heavy rainfall events in South Korea generally arise from mesoscale convective systems embedded in these synoptic scale disturbances. In weather radar data with high temporal and spatial resolution, accurate estimation of rain rate from radar reflectivity data is too difficult. Z-R relationship (Marshal and Palmer 1948) have adapted representatively. In addition to, several methods such as support vector machine (SVM), neural network, Fuzzy logic, Kriging were utilized in order to improve the accuracy of rain rate. These methods show the different quantitative precipitation estimation (QPE) and the performances of accuracy are different for heavy precipitation cases. In this study, in order to improve the accuracy of QPE for localized heavy precipitation, ensemble method for Z-R relationship and various techniques was tested. This QPE ensemble method was developed by a concept based on utilizing each advantage of precipitation calibration methods. The ensemble members were produced for a combination of different Z-R coefficient and calibration method.

    2017-04-01

    Fiber Reinforced Polymer or Plastic (FRP) composites have been rapidly increasing in the aerospace, automotive and marine industry, and civil engineering, because these composites show superior characteristics such as outstanding strength and stiffness, low weight, as well as anti-corrosion and easy production. Generally, the advancement of materials calls for correspondingly advanced methods and technologies for inspection and failure detection during production or maintenance, especially in the area of nondestructive testing (NDT). Among numerous inspection techniques, microwave sensing methods can be effectively used for NDT of FRP composites. FRP composite materials can be produced using various structures and materials, and various defects or flaws occur due to environmental conditions encountered during operation. However, reliable, low-cost, and easy-to-operate NDT methods have not been developed and tested. FRP composites are usually produced as multilayered structures consisting of fiber plate, matrix and core. Therefore, typical defects appearing in FRP composites are disbondings, delaminations, object inclusions, and certain kinds of barely visible impact damages. In this paper, we propose a microwave NDT method, based on synthetic aperture radar (SAR) imaging algorithms, for stand-off imaging of internal delaminations. When a microwave signal is incident on a multilayer dielectric material, the reflected signal provides a good response to interfaces and transverse cracks. An electromagnetic wave model is introduced to delineate interface widths or defect depths from the reflected waves. For the purpose of numerical analysis and simulation, multilayered composite samples with various artificial defects are assumed, and their SAR images are obtained and analyzed using a variety of high-resolution wideband waveforms.

    The Inilchek Glacier, located in the Tien Shan Mountains, central Asia, is unique among mid-latitude glaciers because of its relatively large average annual accumulation. In July 2000, two ice cores of 162 and 167 meters (m) in length were collected from the Inilchek Glacier for (chlorine-36) 36Cl analysis a part of a collaborative international effort to study the environmental changes archived in mid-latitude glaciers worldwide. The average annual precipitation at the collection site was calculated to be 1.6 m. In contrast, the reported average annual accumulations at the high-latitude Dye-3 glacial site, Greenland, the mid-latitude Guliya Ice Cap, China, and the mid-latitude Upper Fremont Glacier, Wyoming, USA, were 0.52, 0.16 and 0.76 m, respectively. The resolution of the 36Cl record in one of the Inilchek ice cores was from 2 to 10 times higher than the resolution of the records at these other sites and could provide an opportunity for detailed study of environmental changes that have occurred over the past 150 years. Despite the differences in accumulation among these various glacial sites, the 36Cl profile and peak concentrations for the Inilchek ice core were remarkably similar in shape and magnitude to those for ice cores from these other sites. The 36Cl peak concentration from 1958, the year during the mid-1900s nuclear-weapons-tests period when 36Cl fallout was largest, was preserved in the Inilchek core at a depth of 90.56 m below the surface of the glacier (74.14-m-depth water equivalent) at a concentration of 7.7 ?? 105 atoms of 36Cl/gram (g) of ice. Peak 36Cl concentrations from Dye-3, Guliya and the Upper Fremont glacial sites were 7.1 ?? 105, 5.4 ?? 105 and 0.7 ?? 105 atoms of 36Cl/g of ice, respectively. Measurements of 36Cl preserved in ice cores improve estimates of historical worldwide atmospheric deposition of this isotope and allow the sources of 36Cl in ground water to be better identified. ?? 2004 Published by Elsevier B.V.

    2004-06-01

    Full Text Available This paper examines the impacts of the l998 ban on Oman fish exports to the EU markets and ensuing the internationalization of Oman fish companies. The ban raises two concerns that the paper intends to answer: (i how firms have responded to surmount the ban, and (ii which strategies are more effective in the process of internationalization. The paper distinguishes three sets of actions: during the ban and immediate actions; short term actions; and long term actions. Besides government support for the implementation of international norms of quality and safety control, firms have responded individually to the EU ban. The actions subsequently undertaken by firms in response to the ban were selected: identification of new markets (alternatives; implementation of the required regulations and needed support to continue exporting to traditional European markets (competence; and long term business and marketing strategies (strategic thinking. These actions or steps represent the internationalization process or approach followed by the fisheries firms in Oman. All these actions have been undertaken after the EU ban, which leads to the conclusion that the ban has indeed worked as a driving force to internationalize, i.e. to develop the requisites of international markets.

  18. Should selecting saviour siblings be banned?

    Science.gov (United States)

    Sheldon, S; Wilkinson, S

    2004-12-01

    By using tissue typing in conjunction with preimplantation genetic diagnosis doctors are able to pick a human embryo for implantation which, if all goes well, will become a "saviour sibling", a brother or sister capable of donating life-saving tissue to an existing child. This paper addresses the question of whether this form of selection should be banned and concludes that it should not. Three main prohibitionist arguments are considered and found wanting: (a) the claim that saviour siblings would be treated as commodities; (b) a slippery slope argument, which suggests that this practice will lead to the creation of so-called "designer babies"; and (c) a child welfare argument, according to which saviour siblings will be physically and/or psychologically harmed.

  19. Experience of Japan in Achieving a Total Ban on Asbestos

    Sugio Furuya

    2017-10-01

    Full Text Available This paper aims to examine the process through which a total ban on asbestos was achieved in Japan. We reconstructed the process, analyzed the roles of involved parties/events, and drew lessons from the Japanese experience of achieving the ban. In Japan, a bill to phase out asbestos was proposed in 1992 but rejected without deliberation. Wide support for such a ban subsequently grew, however, largely due to the actions of trade unions and civil societies in establishing a coalition, raising awareness, organizing asbestos victims and their families, and propagating information on international developments. A governmental decision towards a ban was made in 2002 based on several national and international factors. A huge asbestos scandal in 2005 preponed the achievement of a total ban and led to the establishment of comprehensive measures to tackle asbestos issues. However, challenges remain for the elimination of asbestos-related diseases.

  1. To ban or not to ban: direct-to-consumer advertising and human rights analysis

    Directory of Open Access Journals (Sweden)

    Alex Wellington

    2010-12-01

    Full Text Available The issues surrounding Direct-To-Consumer Advertising of pharmaceuticals are ripe for scrutiny through the lens of Human Rights analysis. Among the human rights most decisively engaged by DTCA is the right to autonomy in health-related decision making, which in turn incorporates right of access to health-related information. The latter incorporates, in part, right of access to reliable and beneficial information through the avenues of commercial speech among others. Another crucial human right is the right not to be harmed by unsafe consumer products through corporate malfeasance or negligence. The most commonly invoked policy options in the context of DTCA are either an outright ban or strengthening regulatory oversight in combination with voluntary guidelines. Banning Direct-To-Consumer Advertising risks being both over inclusive and under inclusive as a policy option. A wholesale ban risks being over inclusive in that it could deprive consumers of information about medications with a positive benefit-risk profile, ones that could enhance their quality of health and well being. Thus it risks being overly paternalistic. Banning DTCA, by itself, is under inclusive in that it is insufficient to address the ways that unadvertised drugs can pose significant risks to consumers. Other policy measures would be most optimal to deal with the very serious deficits in the processes by which prescription drugs undergo clinical trials, and garner regulatory approval prior to their promotion in the marketplace. A more finely tuned approach to regulatory oversight is endorsed, one involving a proactive and precautionary approach reliant upon prior approval. Such an approach could help to address the very serious concerns about potential infringements of the human right not to be harmed by unsafe consumer products through corporate malfeasance or negligence.

  2. OpenBAN: An Open Building ANalytics Middleware for Smart Buildings

    Directory of Open Access Journals (Sweden)

    Pandarasamy Arjunan

    2016-03-01

    Full Text Available Towards the realization of smart building applications, buildings are increasingly instrumented with diverse sensors and actuators. These sensors generate large volumes of data which can be analyzed for optimizing building operations. Many building energy management tasks such as energy forecasting, disaggregation, among others require complex analytics leveraging collected sensor data. While several standalone and cloud-based systems for archiving, sharing and visualizing sensor data have emerged, their support for analyzing sensor data streams is primitive and limited to rule-based actions based on thresholds and simple aggregation functions. We develop OpenBAN, an open source sensor data analytics middleware for buildings, to make analytics an integral component of modern smart building applications. OpenBAN provides a framework of extensible sensor data processing elements for identifying various building context, which different applications can leverage. We validate the capabilities of OpenBAN by developing three representative real-world applications which are deployed in our test-bed buildings: (i household energy disaggregation, (ii detection of sprinkler usage from water meter data, and (iii electricity demand forecasting. We also provide a preliminary system performance of OpenBAN when deployed in the cloud and locally.

    Food subsidies have the potential to modify ecosystems and affect the provision of goods and services. Predictable Anthropogenic Food Subsidies (PAFS) modify ecosystems by altering ecological processes and food webs. The global concern over the effects of PAFS in ecosystems has led to development of environmental policies aimed at curbing the production or ultimately banning of PAFS. However, the effects of reducing or banning PAFS are not known. We explore the consequences of PAFS removal in a marine ecosystem under two scenarios: 1) gradual reduction, or 2) an abrupt ban, using a mass balance model to test these hypotheses-The reduction or loss of PAFS will: i) modify trophic levels and food webs through effects on foraging by opportunistic species, ii) increase the resilience of opportunistic species to food shortages, and iii) modify predator-prey interactions through shifts in prey consumption. We found that PAFS lower the trophic levels of opportunistic scavengers and increase their food pathways. Scavengers are able to switch prey when PAFS are reduced gradually but they decline when PAFS are abruptly banned. PAFS reduction to a certain minimal level causes a drop in the ecosystem's stability. We recommend gradual reduction of PAFS to a minimal level that would maintain the ecosystem's stability and allow species exploiting PAFS to habituate to the food subsidy reduction.

    Full Text Available Food subsidies have the potential to modify ecosystems and affect the provision of goods and services. Predictable Anthropogenic Food Subsidies (PAFS modify ecosystems by altering ecological processes and food webs. The global concern over the effects of PAFS in ecosystems has led to development of environmental policies aimed at curbing the production or ultimately banning of PAFS. However, the effects of reducing or banning PAFS are not known. We explore the consequences of PAFS removal in a marine ecosystem under two scenarios: 1 gradual reduction, or 2 an abrupt ban, using a mass balance model to test these hypotheses-The reduction or loss of PAFS will: i modify trophic levels and food webs through effects on foraging by opportunistic species, ii increase the resilience of opportunistic species to food shortages, and iii modify predator-prey interactions through shifts in prey consumption. We found that PAFS lower the trophic levels of opportunistic scavengers and increase their food pathways. Scavengers are able to switch prey when PAFS are reduced gradually but they decline when PAFS are abruptly banned. PAFS reduction to a certain minimal level causes a drop in the ecosystem's stability. We recommend gradual reduction of PAFS to a minimal level that would maintain the ecosystem's stability and allow species exploiting PAFS to habituate to the food subsidy reduction.

    Much academic attention has been directed at analysing energy efficiency investments through the lens of ‘behavioural failure’. These studies have challenged the neoclassical framing of regulation which emphasises the efficiency benefits of price based policy, underpinned by the notion of rational individual self-mastery. The increasing use of a regulatory ban on electric lamps in many countries is one of the most recent and high profile flash points in this dialectic of ‘freedom-versus-the-state’ in the public policy discourse. This paper interrogates this debate through a study of electric lamp diffusion in Germany. It is argued that neoclassical theory and equilibrium analysis is inadequate as a tool for policy analysis as it takes the formation of market institutions, such as existing regulations, for granted. Further still, it may be prone to encourage idealistic debates around such grand narratives which may in practice simply serve those who benefit most from the status quo. Instead we argue for an evolutionary approach which we suggest offers a more pragmatic framing tool which focuses on the formation of market institutions in light of shifting social norms and political goals—in our case, progress towards energy efficiency and environmental goals. - Highlights: • Empirical data on the ban of incandescent lamps in Germany is presented. • The political debate on the ban is positioned within key bodies of theory. • Discourse was found to have positively influenced diffusion of efficient lighting. • Tools for the reframing of political debate are proposed for policy makers

    Understanding how heat is transported, stored and exchanged across fractured media is becoming increasingly relevant in our society, as manifested from the growing popularity of modern technologies relying on the subsurface to either source or store heat. One good example is the utilization of heat from deep hydrothermal or petrothermal systems to generate electricity for base load power generation, a technology also known as deep geothermal energy (DGE). While very attractive in principle, the number of geothermal fields producing economical levels of electricity to this day is still very limited - largely due to the difficulty of either locating deep reservoirs that are both sufficiently hot and permeable or, in the absence of the latter, creating them. In this context, the Swiss Competence Center for Energy Research - Supply of Electricity (SCCER - SoE) is carrying out an in situ stimulation and circulation (ISC) experiment at the Grimsel Test Site (GTS), an underground rock lab located in the Aar massif, in the Swiss Alps. The circulation experiment planned for the post-stimulation phase represents one of the key components of this experimental research program, and the outcome of this test is expected to ultimately provide key insights in the factors controlling the performance of enhanced geothermal reservoirs. Therefore, to support the design of this experiment, short-term thermal tracer tests (TTT) were conducted with the objective to (i) assess the feasibility of conducting TTTs in a relatively intact granite (where fluid flow is controlled by a limited number of discrete fractures); (ii) determine optimal experimental setups; and to ultimately (iii) monitor thermal breakthroughs at high spatial and temporal resolution, providing insights on heat transport and complementing the characterization of hydrogeological conditions carried out through conventional means (e.g. hydraulic and/or solute tracer tests). Presented herein are the results of a 10-day

    This study examined whether a policy of banning tobacco product retailers from operating within 1000 feet of schools could reduce existing socioeconomic and racial/ethnic disparities in tobacco retailer density. We geocoded all tobacco retailers in Missouri (n = 4730) and New York (n = 17 672) and linked them with Census tract characteristics. We then tested the potential impact of a proximity policy that would ban retailers from selling tobacco products within 1000 feet of schools. Our results confirmed socioeconomic and racial/ethnic disparities in tobacco retailer density, with more retailers found in areas with lower income and greater proportions of African American residents. A high proportion of retailers located in these areas were in urban areas, which also have stores located in closer proximity to schools. If a ban on tobacco product sales within 1000 feet of schools were implemented in New York, the number of tobacco retailers per 1000 people would go from 1.28 to 0.36 in the lowest income quintile, and from 0.84 to 0.45 in the highest income quintile. In New York and Missouri, a ban on tobacco product sales near schools would either reduce or eliminate existing disparities in tobacco retailer density by income level and by proportion of African American. Proximity-based point of sale (POS) policies banning tobacco product sales near schools appear to be more effective in reducing retailer density in lower income and racially diverse neighborhoods than in higher income and white neighborhoods, and hold great promise for reducing tobacco-related disparities at the POS. Given the disparities-reducing potential of policies banning tobacco product sales near schools, jurisdictions with tobacco retailer licensing should consider adding this provision to their licensing requirements. Since relatively few jurisdictions currently ban tobacco sales near schools, future research should examine ways to increase and monitor the uptake of this policy, and assess

    Background All forms of asbestos are now banned in 52 countries. Safer products have replaced many materials that once were made with it. Nonetheless, many countries still use, import, and export asbestos and asbestos-containing products, and in those that have banned other forms of asbestos, the so-called “controlled use” of chrysotile asbestos is often exempted from the ban. In fact, chrysotile has accounted for > 95% of all the asbestos used globally. Objective We examined and evaluated the literature used to support the exemption of chrysotile asbestos from the ban and how its exemption reflects the political and economic influence of the asbestos mining and manufacturing industry. Discussion All forms of asbestos, including chrysotile, are proven human carcinogens. All forms cause malignant mesothelioma and lung and laryngeal cancers, and may cause ovarian, gastrointestinal, and other cancers. No exposure to asbestos is without risk. Illnesses and deaths from asbestos exposure are entirely preventable. Conclusions All countries of the world have an obligation to their citizens to join in the international endeavor to ban the mining, manufacture, and use of all forms of asbestos. An international ban is urgently needed. There is no medical or scientific basis to exempt chrysotile from the worldwide ban of asbestos. PMID:20601329

    2017-07-01

    We sought to evaluate changes in countries' enacting advertising bans after the effect of ratifying the WHO Framework Convention on Tobacco Control (FCTC). We compared adoption of advertising bans on five areas (TV and radio, print media, billboards, point-of-sale, sponsorship) in countries that did versus did not ratify the FCTC, accounting for years since the ratification of the Convention. On average, passage of complete advertising bans accelerated after FCTC ratification. The development was strongest among lower middle-income countries. Lack of state capacity was associated with lower likelihood of countries implementing complete advertising bans. Implementation of complete advertising bans slowed after 2007. Implementation of FCTC Article 13 was followed by increased progress towards complete advertising bans, but progress is incomplete, especially among low-income countries. Low-income countries need comprehensive support to implement FCTC as part of a broad effort to reinvigorate progress on global implementation of the FCTC. Enforcing complete bans requires constant monitoring and attacking of tobacco industry efforts to circumvent them. Published by the BMJ Publishing Group Limited.

    Many flash lidar applications continue to demand higher three-dimensional image resolution beyond the current state-of-the-art technology of the detector arrays and their associated readout circuits. Even with the available number of focal plane pixels, the required number of photons for illuminating all the pixels may impose impractical requirements on the laser pulse energy or the receiver aperture size. Therefore, image resolution enhancement by means of a super-resolution algorithm in near real time presents a very attractive solution for a wide range of flash lidar applications. This paper describes a superresolution technique and illustrates its performance and merits for generating three-dimensional image frames at a video rate.

    A muon detection system using segmented and instrumented absorber has been designed for high-energy heavy-ion collision experiments to be held at GSI, Darmstadt, Germany. The muon detector system is mounted downstream of a Silicon Tracking System. The reconstructed tracks from the STS are to be matched to the hits in the GEM detector. For reconstructing track in the GEM Detector, track point resolution is an important issue. We report her first time the track point resolution of the GEM detector.

    Recent advances in medical and electronic technologies have introduced the use of Body Area Networks as a part of e-health, for constant and accurate monitoring of patients and the transmission as well as processing of the data to develop a holistic Electronic Health Record. The rising global population, different BAN manufacturers and a variety of medical systems pose the issue of interoperability between BANs and systems as well as the proper way to propagate medical data in an organized and efficient manner. In this paper, we describe BANs and propose the use of certain web technologies to address this issue.

    The spatial resolution of the pain system has not been studied in depth, and results are contradictory regarding the gradient of spatial resolution. Microneurographic recordings have revealed smaller receptive fields and higher density of nociceptors in more distal than proximal leg regions, whereas histological studies report higher density of C-fibers in more proximal than distal body regions. Due to this controversy, we conducted various psychophysical tests in order to examine the nociceptive spatial resolution and its gradient. Heat-pain threshold (HPT), perceived pain intensity, spatial summation (SS) of pain, two-point discrimination (2PD) of pain, and pain localization were measured in four body regions: upper back, thigh, lower leg, and foot. The highest HPT was demonstrated in the lower leg as compared with more proximal regions (P resolution has a proximal-to-distal pattern of performance, namely that the spatial resolution of pain is finer in more distal than proximal body regions, similar to that of the touch system.

    Wildlife trade is a major pathway for introduction of invasive species worldwide. However, how exactly wildlife trade influences invasion risk, beyond the transportation of individuals to novel areas, remains unknown. We analyze the global trade network of wild-caught birds from 1995 to 2011 as reported by CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). We found that before the European Union ban on imports of wild-caught birds, declared in 2005, invasion risk was closely associated with numbers of imported birds, diversity of import sources, and degree of network centrality of importer countries. After the ban, fluxes of global bird trade declined sharply. However, new trade routes emerged, primarily toward the Nearctic, Afrotropical, and Indo-Malay regions. Although regional bans can curtail invasion risk globally, to be fully effective and prevent rerouting of trade flows, bans should be global.

    Anti-personnel (AP) landmines have historically been used as a military tool. The humanitarian consequences of AP mines have generated support for an absolute ban on their use. Based on pre-existing principles of humanitarian law, non-governmental organizations (NGOs) campaigned for an international agreement banning AP mines. Canada and a group of like-minded states and NGOs provided the leadership and momentum necessary to gain a broad support for the Ottawa Treaty, which prohibits AP mines...

    Full Text Available Many developed countries have banned the use of asbestos, but not the United States. There have, however, been multiple efforts in the US to establish strict exposure standards, to limit asbestos use, and to seek compensation through the courts for asbestos-injured workers’ In consequence of these efforts, asbestos use has declined dramatically, despite the absence of a legally mandated ban. This manuscript presents a historical review of these efforts.

    In Korea, registration of paraquat-containing herbicides was canceled in November 2011, and sales thereof were completely banned in November 2012. We evaluated the effect of the paraquat ban on the epidemiology and mortality of herbicide-induced poisoning. This retrospective study analyzed patients treated for herbicide poisoning at 17 emergency departments in South Korea between January 2010 and December 2014. The overall and paraquat mortality rates were compared pre- and post-ban. Factors associated with herbicide mortality were evaluated using logistic analysis. To determine if there were any changes in the mortality rates before and after the paraquat sales ban and the time point of any such significant changes in mortality, R software, version 3.0.3 (package, bcp) was used to perform a Bayesian change point analysis. We enrolled 2257 patients treated for herbicide poisoning (paraquat=46.8%). The overall and paraquat poisoning mortality rates were 40.6% and 73.0%, respectively. The decreased paraquat poisoning mortality rate (before, 75% vs. after, 67%, p=0.014) might be associated with increased intentionality. The multivariable logistic analysis revealed the paraquat ban as an independent predictor that decreased herbicide poisoning mortality (p=0.035). There were two major change points in herbicide mortality rates, approximately 3 months after the initial paraquat ban and 1 year after complete sales ban. This study suggests that the paraquat ban decreased intentional herbicide ingestion and contributed to lowering herbicide poisoning-associated mortality. The change point analysis suggests a certain timeframe was required for the manifestation of regulatory measures outcomes. © Copyright: Yonsei University College of Medicine 2017

  19. DYNAMIC SOFTWARE TESTING MODELS WITH PROBABILISTIC PARAMETERS FOR FAULT DETECTION AND ERLANG DISTRIBUTION FOR FAULT RESOLUTION DURATION

    2016-07-01

    Full Text Available Subject of Research.Software reliability and test planning models are studied taking into account the probabilistic nature of error detection and discovering. Modeling of software testing enables to plan the resources and final quality at early stages of project execution. Methods. Two dynamic models of processes (strategies are suggested for software testing, using error detection probability for each software module. The Erlang distribution is used for arbitrary distribution approximation of fault resolution duration. The exponential distribution is used for approximation of fault resolution discovering. For each strategy, modified labeled graphs are built, along with differential equation systems and their numerical solutions. The latter makes it possible to compute probabilistic characteristics of the test processes and states: probability states, distribution functions for fault detection and elimination, mathematical expectations of random variables, amount of detected or fixed errors. Evaluation of Results. Probabilistic characteristics for software development projects were calculated using suggested models. The strategies have been compared by their quality indexes. Required debugging time to achieve the specified quality goals was calculated. The calculation results are used for time and resources planning for new projects. Practical Relevance. The proposed models give the possibility to use the reliability estimates for each individual module. The Erlang approximation removes restrictions on the use of arbitrary time distribution for fault resolution duration. It improves the accuracy of software test process modeling and helps to take into account the viability (power of the tests. With the use of these models we can search for ways to improve software reliability by generating tests which detect errors with the highest probability.

    Full Text Available Abstract Background Tobacco smoking remains the leading cause of preventable death in America, claiming 450,000 lives annually. Chronic Obstructive Pulmonary Disease, caused by smoking in the vast majority of cases, became the third leading cause of death in the U.S. in 2008. The burden of asthma, often exacerbated by tobacco exposure, has widespread clinical and public health impact. Despite this considerable harm, we know relatively little about the natural history of lung disease and respiratory impairment in adults, especially after smoking cessation. Methods/Design Our paper describes the design and rationale for using the 2004 Federal Bureau of Prisons tobacco ban to obtain insights into the natural history of respiratory diseases in adult men and women of different races/ethnicities who are imprisoned in federal medical facilities. We have developed a longitudinal study of new prison arrivals, with data to be collected from each participant over the course of several years, through the use of standardized questionnaires, medical chart reviews, lung function tests, six-minute walk tests, and stored serum for the analysis of present and future biomarkers. Our endpoints include illness exacerbations, medication and health services utilization, lung function, serum biomarkers, and participants’ experience with their health and nicotine addiction. Discussion We believe the proposed longitudinal study will make a substantial contribution to the understanding and treatment of respiratory disease and tobacco addiction.

    Objectives. A common critique of direct democracy posits that minority rights are endangered by citizen legislative institutions. By allowing citizens to directly create public policy, these institutions avoid the filtering mechanisms of representative democracy that provide a check on the power of the majority. Empirical research, however, has produced conflicting results that leave the question of direct democracy's effect on minority rights open to debate. This article seeks to empirically test this critique using a comparative, dynamic approach.Methods. I examine the diffusion of same-sex marriage bans in the United States using event-history analysis, comparing direct-democracy states to non-direct-democracy states.Results. The results show that direct-democracy states are significantly more likely than other states to adopt same-sex marriage bans.Conclusion. The findings support the majoritarian critique of direct democracy, suggesting that the rights of minority groups are at relatively higher risk under systems with direct democracy.

    Smoking bans are considered one of the most effective policies to reduce population exposure to tobacco smoke and prevent adverse health outcomes. However, evidence on the effect of contextual variables on the effectiveness of smoking bans is still lacking. The patchwork of cantonal smoke-free laws in Switzerland was used as a quasi-experimental setting to assess changes after their introduction in: hospitalisations and mortality due to cardiorespiratory diseases in adults; total hospitalisations and hospitalisations due to respiratory disorders in children; and the modifying effects of contextual factors and the effectiveness of the laws. Using hospital and mortality registry data for residents in Switzerland (2005-2012), we conducted canton-specific interrupted time-series analyses followed by random effects meta-analyses to obtain nationwide smoking ban estimates by subgroups of age, sex and causes of hospitalisation or death. Heterogeneity of the impact caused by strictness of the ban and other smoking-related characteristics of the cantons was explored through meta-regression. Total hospitalisation rates due to cardiovascular and respiratory diseases did not significantly change after the introduction of the ban. Post-ban changes were detected in ischaemic heart disease hospitalisations, with a 2.5% reduction (95% confidence interval [CI)] -6.2 to 1.3%) for all ages and 5.5% (95% CI -10.8 to -0.2%) in adults 35-64 years old. Total mortality due to respiratory diseases decreased by 8.2% (95% CI -15.2 to -0.6%) over all ages, and chronic obstructive pulmonary disease mortality decreased by 14.0% (95% CI -22.3 to -4.5%) in adults ≥65 years old. Cardiovascular mortality did not change after the introduction of the ban, but there was an indication of post-ban reductions in mortality due to hypertensive disorders (-5.4%, 95% CI -12.6 to 2.3%), and congestive heart failure (-6.0%, 95% CI -14.5 to 3.4%). No benefits were observed for hospitalisations due to

    The combination of resting-state functional MRI (R-fMRI) technique and graph theoretical approaches has emerged as a promising tool for characterizing the topological organization of brain networks, that is, functional connectomics. In particular, the construction and analysis of high-resolution brain connectomics at a voxel scale are important because they do not require prior regional parcellations and provide finer spatial information about brain connectivity. However, the test-retest reliability of voxel-based functional connectomics remains largely unclear. This study tended to investigate both short-term (∼20 min apart) and long-term (6 weeks apart) test-retest (TRT) reliability of graph metrics of voxel-based brain networks. Based on graph theoretical approaches, we analyzed R-fMRI data from 53 young healthy adults who completed two scanning sessions (session 1 included two scans 20 min apart; session 2 included one scan that was performed after an interval of ∼6 weeks). The high-resolution networks exhibited prominent small-world and modular properties and included functional hubs mainly located at the default-mode, salience, and executive control systems. Further analysis revealed that test-retest reliabilities of network metrics were sensitive to the scanning orders and intervals, with fair to excellent long-term reliability between Scan 1 and Scan 3 and lower reliability involving Scan 2. In the long-term case (Scan 1 and Scan 3), most network metrics were generally test-retest reliable, with the highest reliability in global metrics in the clustering coefficient and in the nodal metrics in nodal degree and efficiency. We showed high test-retest reliability for graph properties in the high-resolution functional connectomics, which provides important guidance for choosing reliable network metrics and analysis strategies in future studies. © 2015 John Wiley & Sons Ltd.

    Using a 47 GeV electron beam, the Final Focus Test Beam (FFTB) produces vertical spot sizes around 70 nm. These small beam sizes introduce an excellent opportunity to develop and test high resolution Radio Frequency Beam Position Monitors (RF-BPMs). These BPMs are designed to measure pulse to pulse beam motion (jitter) at a theoretical resolution of approximately 1 nm. The beam induces a TM{sub 110} mode with an amplitude linearly proportional to its charge and displacement from the BPM's (cylindrical cavity) axis. The C-band (5,712 MHz) TM{sub 110} signal is processed and converted into beam position for use by the Stanford Linear Collider (SLC) control system. Presented are the experimental procedures, acquisition, and analysis of data demonstrating resolution of jitter near 25 nm. With the design of future e{sup +}e{sup -} linear colliders requiring spot sizes close to 3 nm, understanding and developing RF-BPMs will be essential in resolving and controlling jitter.

    High-resolution satellite imagery is a promising tool for providing coarse information about polar species abundance and distribution, but current applications are limited. With polar bears (Ursus maritimus), the technique has only proven effective on landscapes with little topographic relief that are devoid of snow and ice, and time-consuming manual review of imagery is required to identify bears. Here, we evaluated mechanisms to further develop methods for satellite imagery by examining data from Rowley Island, Canada. We attempted to automate and expedite detection via a supervised spectral classification and image differencing to expedite image review. We also assessed what proportion of a region should be sampled to obtain reliable estimates of density and abundance. Although the spectral signature of polar bears differed from nontarget objects, these differences were insufficient to yield useful results via a supervised classification process. Conversely, automated image differencing—or subtracting one image from another—correctly identified nearly 90% of polar bear locations. This technique, however, also yielded false positives, suggesting that manual review will still be required to confirm polar bear locations. On Rowley Island, bear distribution approximated a Poisson distribution across a range of plot sizes, and resampling suggests that sampling >50% of the site facilitates reliable estimation of density (CV in certain areas, but large-scale applications remain limited because of the challenges in automation and the limited environments in which the method can be effectively applied. Improvements in resolution may expand opportunities for its future uses.

    Modifications to the ILL high-resolution powder diffractometer D1A will improve its efficiency by an order of magnitude. Novel features include a monochromator take-off angle of 122deg giving high resolution at high angles, a bank of eight 20 x 100 mm high efficiency mylar collimators with He 3 counters, and the possibility of working at high pressures (up to 45 kbar), or low and very high temperatures (1.5K to 2800K). The performance expected of the instrument is illustrated by the refinement of data collected on a standard Al 2 O 3 sample supplied by the Neutron Diffraction Commission. Anisotropic vibrational amplitudes as well as atomic co-ordinates have been determined quite precisely. When completed, D1A will be unique for the precise measurement of moderately complex crystal structures under 'difficult' conditions, especially for the study of phase transitions. But in fact, it is only an indication of a type of more powerful machine described recently in Nuclear Instruments and Methods which could be built on a beam tube of a high-flux reactor

    2000-01-01

    The purpose of this work is a demonstration of the basic possibility of the practical realization of the 'moving source' idea for X-ray diffraction with nanosecond time resolution. The idea of 'moving source' was published earlier. The principle of this idea is: a quick change of electron trajectory by the kicker is responsible for a quick change of direction of synchrotron radiation (SR). In such a way a 'moving source' can be created. Using the 'moving source' it is possible to scan a sample with the SR beam. As a result, diffraction with nanoseconds time resolution can be achieved . The experiment at the VEPP-3 storage ring has confirmed such a possibility. The following answers to the main questions were received: (1) SR intensities are enough for obtaining satisfactory statistics from one bunch (2) it is possible to realize synchronization of an impact with the motion of electrons in the storage ring and with the systems of image registration ; (3) it is possible to compensate the betatron oscillation wh...

    The capability of the noble gas component of the International Monitoring System as a verification tool for the Comprehensive Nuclear-Test-Ban Treaty is deteriorated by a background of radioxenon emitted by civilian sources. One of the possible approaches to deal with this issue, is to simulate the daily radioxenon concentrations from these civilian sources at noble gas stations by using atmospheric transport models. In order to accurately quantify the contribution from these civilian sources, knowledge on the releases is required. However, such data are often not available and furthermore it is not clear what temporal resolution such data should have. In this paper, we assess which temporal resolution is required to best model the 133 Xe contribution from civilian sources at noble gas stations in an operational context. We consider different sampling times of the noble gas stations and discriminate between nearby and distant sources. We find that for atmospheric transport and dispersion problems on a scale of 1000 km or more, emission data with subdaily temporal resolution is generally not necessary. However, when the source-receptor distance decreases, time-resolved emission data become more important. The required temporal resolution of emission data thus depends on the transport scale of the problem. In the context of the Comprehensive Nuclear-Test-Ban Treaty, where forty noble gas stations will monitor the whole globe, daily emission data are generally sufficient, but for certain meteorological conditions, better temporally resolved emission data are required.

    Following the passage of the Family Smoking Prevention and Tobacco Control Act in 2009, flavoured cigarettes, including clove cigarettes, were banned based on the rationale that such cigarettes appealed to youth. However, the ban on characterising flavours was not extended to cigars. This study reviewed industry documents from Kretek International, the parent company behind Djarum clove cigars, to document the changes in their marketing and production strategies following the flavour ban on cigarettes. To assess sales trends following the ban, data for clove cigar sales in the USA from 2009 to 2012 were analysed using Nielsen's Convenience Track retail scanner database. Additionally, data on tobacco imports to the USA from Indonesia were obtained from the USDA Foreign Agricultural Service's Global Agricultural Trade System for the years 2008-2012. In anticipation of Food and Drug Administration's (FDA) flavour ban on cigarettes and recognising the regulatory advantages of cigars, Kretek International began developing Djarum clove cigars in 2007. Immediately following the flavour ban, sales of this product increased by more than 1400% between 2009 and 2012. During this same period, tobacco imports to the USA from Indonesia, a leader in clove tobacco production, shifted from cigarettes to almost exclusively cigars. Kretek International, like other tobacco manufacturers, manipulated its products following the Family Smoking Prevention and Tobacco Control Act as a way to capitalise on regulatory loopholes and replace its now banned clove cigarettes. As a result, consumption of the company's Djarum clove cigars increased exponentially in recent years. Published by the BMJ Publishing Group Limited.

    2001-01-01

    With the first version of the IDC software all known radionuclides, less the natural ones and one 'naturalised' man-made one, caused a spectrum measured in the IMS network to be characterised as interesting from a CTBT point of view. But this is really not true for the majority of nuclides, so a change has been made to let only nuclides from a limited set of so called CTBT relevant nuclides have an impact on the characterization scheme. In the present paper the concept of CTBT relevance is analysed and a set of 96 relevant nuclides are defined. Out of these 51 are fission products and 41 are neutron activation products. There are also 4 nuclides which are residues from the nuclear fuel itself or added tracers. (orig.) [de

    The important issue of data integrity in the CTBT International Monitoring System (IMS) is discussed and a brief tutorial on data authentication techniques is offered. The utilization of data authentication as a solution to the data integrity problem is evaluated. Public key data authentication is recommended for multilateral monitoring regimes such as the CTBT. The ramifications and system considerations of applying data authentication at various locations in the IMS, or not at all, are reviewed in a data surety context. The paper concludes with a recommendation of authenticating data at all critical monitoring stations

    Full Text Available This study explored the influence of the spatial resolution of a gridded weather dataset when inputted in the soil and water assessment tool (SWAT over the Garonne River watershed. Several datasets are compared: ground-based weather stations, the 8-km SAFRAN product (Système d’Analyse Fournissant des Renseignements Adaptés à la Nivologie, the 0.5° CFSR product (Climate Forecasting System Reanalysis and several derived SAFRAN grids upscaled to 16, 32, 64 and 128 km. The SWAT model, calibrated on weather stations, was successively run with each gridded weather dataset. Performances with SAFRAN up to 64 or 128 km were poor, due to a contraction of the spatial variance of daily precipitation. Performances with 8-km SAFRAN are similar to that of the aggregated 16- and 32-km SAFRAN grids. The ~30-km CFSR product was found to perform well at some sites, while in others, its performance was considerably inferior because of grid points where precipitation was overestimated. The same problem was found in the calibration, where data at some weather stations did not appear to be representative of the subwatershed in which they are used to compute hydrology. These results suggest that the difference in the representation of the climate was more influential than its spatial resolution, an analysis that was confirmed by similar performances obtained with the SWAT model calibrated on the 16- and 32-km SAFRAN grids. However, the better performances obtained from these two weather datasets than from the ground-based stations’ dataset confirmed the advantage of using the SAFRAN product in SWAT modelling.

    Using an isolated Milky Way-mass galaxy simulation, we compare results from nine state-of-the-art gravito-hydrodynamics codes widely used in the numerical community. We utilize the infrastructure we have built for the AGORA High-resolution Galaxy Simulations Comparison Project. This includes the common disk initial conditions, common physics models (e.g., radiative cooling and UV background by the standardized package Grackle) and common analysis toolkit yt, all of which are publicly available. Subgrid physics models such as Jeans pressure floor, star formation, supernova feedback energy, and metal production are carefully constrained across code platforms. With numerical accuracy that resolves the disk scale height, we find that the codes overall agree well with one another in many dimensions including: gas and stellar surface densities, rotation curves, velocity dispersions, density and temperature distribution functions, disk vertical heights, stellar clumps, star formation rates, and Kennicutt–Schmidt relations. Quantities such as velocity dispersions are very robust (agreement within a few tens of percent at all radii) while measures like newly formed stellar clump mass functions show more significant variation (difference by up to a factor of ∼3). Systematic differences exist, for example, between mesh-based and particle-based codes in the low-density region, and between more diffusive and less diffusive schemes in the high-density tail of the density distribution. Yet intrinsic code differences are generally small compared to the variations in numerical implementations of the common subgrid physics such as supernova feedback. Our experiment reassures that, if adequately designed in accordance with our proposed common parameters, results of a modern high-resolution galaxy formation simulation are more sensitive to input physics than to intrinsic differences in numerical schemes.

    The objective of this study was to examine reimbursement trends for emergency provider professional services following the balance billing ban in California. We conducted a blinded web-based survey to collect claims data from emergency providers and billing companies. Members of the California Chapter of the American College of Emergency Physicians (California ACEP) reimbursement committee were invited to participate in the survey. We used a convenience sample of claims to determine payment rates before and after the balance billing ban. We examined a total of 55,243 claims to determine the percentage of charges paid before and after the balance billing ban took effect on October 15, 2008. The overall reduction in percentage of charges paid was 13% in the first year and 19% in the second year following the balance billing ban. The average percentage of charges paid by health plans decreased from 91% to 86% from 2008 to 2010. Payments by risk-bearing organizations decreased from 72% to 46% of charges during the same time frame. Payment rates by subcontracted risk-bearing organizations for non-contracted emergency department professional services declined significantly following the balanced billing ban whereas payment rates by health plans remained relatively stable.

    This paper estimated the association between the U.S. Food and Drug Administration's 2009 ban on flavored cigarettes (which did not apply to menthol cigarettes or tobacco products besides cigarettes) and adolescents' tobacco use. Regression modeling was used to evaluate tobacco use before and after the ban. The analyses controlled for a quadratic time trend, demographic variables, prices of cigarettes and other tobacco products, and teenage unemployment rate. Data from the 1999-2013 National Youth Tobacco Surveys were collected and analyzed in 2016. The sample included 197,834 middle and high schoolers. Outcomes were past 30-day cigarette use; cigarettes smoked in the past 30 days among smokers; rate of menthol cigarette use among smokers; and past 30-day use of cigars, smokeless tobacco, pipes, any tobacco products besides cigarettes, and any tobacco products including cigarettes. Banning flavored cigarettes was associated with reductions in the probability of being a cigarette smoker (17%, pcigarettes smoked by smokers (58%, p=0.005). However, the ban was positively associated with the use by smokers of menthol cigarettes (45%, pcigarette ban did achieve its objective of reducing adolescent tobacco use, but effects were likely diminished by the continued availability of menthol cigarettes and other flavored tobacco products.

    Full Text Available Reliable and optimal exploitation of rapidly developing airborne imaging methods requires geometric and radiometric quality assurance of production systems in operational conditions. Permanent test sites are the most promising approach for cost-efficient performance assessment. Optimal construction of permanent radiometric test sites for high resolution airborne imaging systems is an unresolved issue. The objective of this study was to assess the performance of commercially available gravels and painted and unpainted concrete targets for permanent, open-air radiometric test sites under sub-optimal climate conditions in Southern Finland. The reflectance spectrum and reflectance anisotropy and their stability were characterized during the summer of 2009. The management of reflectance anisotropy and stability were shown to be the key issues for better than 5% reflectance accuracy.

    Proton beam writing is a direct-write technique and a promising method for the micromachining of commodity plastics such as acrylic resins. Herein, we describe the fabrication of microscopic devices made from a relatively thick (∼75 μm) acrylic sheet using proton beam writing. In addition, a software package that converts image pixels into coordinates data was developed, and the successful fabrication of a very fine jigsaw puzzle was achieved. The size of the jigsaw puzzle pieces was 50 × 50 μm. For practical use, a prototype of a line and space test-chart was also successfully fabricated for the determination of spatial resolution in neutron radiography

    The accurate identification of botanical origin in commercial products is important to ensure food authenticity and safety for consumers. The Dendrobium species have long been commercialised as functional food supplements and herbal medicines in Asia. Three valuable Dendrobium species, namely Dendrobium officinale, D. huoshanense and D. moniliforme, are often mutually adulterated in trade products in pursuit of higher profit. In this paper, a rapid and reliable semi-quantitative method for identifying the botanical origin of Dendrobium products in terminal markets was developed using high-resolution melting (HRM) analysis with specific primer pairs to target the trnL-F region. The HRM analysis method detected amounts of D. moniliforme adulterants as low as 1% in D. huoshanense or D. officinale products. The results have demonstrated that HRM analysis is a fast and effective tool for the differentiation of these Dendrobium species both for their authenticity as well as for the semi-quantitative determination of the purity of their processed products. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Objective: To correlate tomographic findings with pulmonary function findings, as well as to compare chest X-ray findings with high-resolution computed tomography (HRCT) findings, in patients with silicosis. Methods: A cross-sectional study was conducted in 44 non-smoking patients without a history of tuberculosis. Chest X-ray findings were classified according to the International Labour Organization recommendations. Using a semiquantitative system, the following HRCT findings were measured: the full extent of pulmonary involvement; parenchymal opacities; and emphysema. Spirometry and forced oscillation were performed. Pulmonary volumes were evaluated using the helium dilution method, and diffusing capacity of the lung for carbon monoxide was assessed. Results: Of the 44 patients studied, 41 were male. The mean age was 48.4 years. There were 4 patients who were classified as category 0 based on X-ray findings and as category 1 based on HRCT findings. Using HRCT scans, we identified progressive massive fibrosis in 33 patients, compared with only 23 patients when X-rays were used. Opacity score was found to correlate most closely with airflow, DLCO and compliance. Emphysema score correlated inversely with volume, DLCO and airflow. In this sample of patients presenting a predominance of large opacities (75% of the individuals), the deterioration of pulmonary function was associated with the extent of structural changes. Conclusions: In the early detection of silicosis and the identification of progressive massive fibrosis, HRCT scans are superior to X-rays. (author)

    Objective: To correlate tomographic findings with pulmonary function findings, as well as to compare chest X-ray findings with high-resolution computed tomography (HRCT) findings, in patients with silicosis. Methods: A cross-sectional study was conducted in 44 non-smoking patients without a history of tuberculosis. Chest X-ray findings were classified according to the International Labour Organization recommendations. Using a semiquantitative system, the following HRCT findings were measured: the full extent of pulmonary involvement; parenchymal opacities; and emphysema. Spirometry and forced oscillation were performed. Pulmonary volumes were evaluated using the helium dilution method, and diffusing capacity of the lung for carbon monoxide was assessed. Results: Of the 44 patients studied, 41 were male. The mean age was 48.4 years. There were 4 patients who were classified as category 0 based on X-ray findings and as category 1 based on HRCT findings. Using HRCT scans, we identified progressive massive fibrosis in 33 patients, compared with only 23 patients when X-rays were used. Opacity score was found to correlate most closely with airflow, DLCO and compliance. Emphysema score correlated inversely with volume, DLCO and airflow. In this sample of patients presenting a predominance of large opacities (75% of the individuals), the deterioration of pulmonary function was associated with the extent of structural changes. Conclusions: In the early detection of silicosis and the identification of progressive massive fibrosis, HRCT scans are superior to X-rays. (author)

    One-third of Mexican-American children, in addition to nonsmoker adults, are exposed to secondhand smoke at home, yet few interventions target Mexican-American households. An effective, brief English language program, tested with United Way 2-1-1 callers in Atlanta, increased home smoking bans (confirmed by air monitors). Two randomized controlled trials in North Carolina and Texas replicated those results. We explored factors determining adoption and enforcement of smoking bans in Mexican-American households to inform program linguistic and cultural adaptation to broaden program reach and relevance. Bilingual interviewers recruited convenience samples of Mexican-American smokers and nonsmokers living with at least one smoker in Houston and San Diego households and asked open-ended questions regarding conditions for implementing home and vehicle smoking bans and conditions for varying acceptance of bans. Investigators independently reviewed English transcripts and completed a descriptive analysis using ATLAS.ti. Participants (n = 43) were predominantly female (n = 31), current smokers (n = 26), interviewed in Spanish (n = 26), had annual household incomes less than $30000 (n = 24), and allowed smoking inside the home (n = 24). Themes related to difficulty creating and enforcing bans included courtesy, respect for guests and heads of household who smoke, and gender imbalances in decision making. Participants viewed protecting children's health as a reason for the ban but not protecting adult nonsmokers' health. A dual-language, culturally adapted intervention targeting multigenerational Mexican-American households should address household differences regarding language and consider influences of cultural values on family dynamics and interactions with guests that may weaken bans. Qualitative interviews suggested cultural and family considerations to address in adapting a brief evidence-based smoke-free homes intervention for Mexican Americans, including traditional

    The Conservatism in Typical Vibration Tests was Demonstrated: Vibration test at component level produced conservative force reactions by approximately a factor of 4 (approx.12 dB) as compared to the integrated acoustic test in 2 out of 3 axes. Reaction Forces Estimated at the Base of Equipment Using a Finite Element Based Method were Validated: FEM based estimate of interface forces may be adequate to guide development of vibration test criteria with less conservatism. Element Forces Estimated in Secondary Structure Struts were Validated: Finite element approach provided best estimate of axial strut forces in frequency range below 200 Hz where a rigid lumped mass assumption for the entire electronics box was valid. Models with enough fidelity to represent diminishing apparent mass of equipment are better suited for estimating force reactions across the frequency range. Forward Work: Demonstrate the reduction in conservatism provided by; Current force limited approach and an FEM guided approach. Validate proposed CMS approach to estimate coupled response from uncoupled system characteristics for vibroacoustics.

    The U.S. Senate has approved anti-drug legislation which permanently bans Federal funding for needle-exchange programs. Senator Paul Coverdell of Georgia added the anti-drug legislation to a tobacco bill that is very important to many politicians. During the Senate approval process of this tobacco bill, needle exchange programs were hardly mentioned. If the combined bill reaches the President, it is believed that he will sign it because of the Administration's interest in tobacco legislation. If, however, the tobacco bill is not approved, the funding ban may be attached to other, less controversial legislation.

    The purpose of this study was to examine the proportion of paraquat use among farmers and to describe their epidemiologic characteristics after the paraquat ban in 2012. We interviewed 249 farmers in Korea in 2014. Approximately 20% of the farmers reported using paraquat in 2014. Farmers with longer farming experience, longer pesticide application years, and upland farming reported an increased risk of paraquat use although the trend was not statistically significant. The majority of the farmers used preexisting paraquat (85.7%), but some farmers purchased it illegally (14.3%). Farmers who used paraquat perceived paraquat as a dangerous chemical; however, they disagreed with the necessity of the paraquat ban.

    Of all the methods used for investigating petroleum reservoirs, Well Testing is of particular interest because it proves reservoir potential and confirms well performance. Well testing involves flowing the well at a control rate and measuring the reservoir response. Conventional well testing is performed in a completed well while high resolution well testing applies to uncompleted well, using wireline technology. This paper describes the use of high technology wireline formation testers to improve reservoir characterization. The Schlumberger formation testing tools (PressureXpress and Modular Reservoir Dynamic Tester) are presented, with applications in geological modeling, drilling, completion and testing optimization as well as formation evaluation. One of the main goal of the study was to identify the gas (oil) saturated layers, to avoid testing unproductive zones. In well K4 utilization of formation tester allowed to point only the potential layers in a sand shale reservoir and a thorough study of these zones has allow the determination of potential reserves. Second successful objective was also to determine eventual compartments in the reservoir, i.e. which reservoir where in the same hydrodynamic system. Last but no least it has allowed an estimation of the free water level. Combination of formation tester with FMI has also helped to visualize the Free Water Level (FWL) in the well, and to determine, in real time, the different points to be tested with XPT. FMI was also of huge benefits in these fractured reservoirs. The determination of free water level and the identification of hydrocarbon saturated layers reduce the cost of completion and conventional testing. Downhole fluid analysis provides a unique solution to the understanding of complex reservoirs. Based on the lessons learned, Improvements have been proposed for future operations.

    The ICH M7 Guideline requires low level control of mutagenic impurities in pharmaceutical products to minimize cancer risk in patients (ICHM7, 2014). Bacterial mutagenicity (Ames) data is generally used to determine mutagenic and possible carcinogenic potential of compounds. Recently, a publication on experiences of using two in silico systems to identify potentially mutagenic impurities highlighted the importance of performing a critical review of published Ames data utilized as part of a mutagenicity assessment of impurities (Greene et al., 2015). Four compounds (2-amino-5-hydroxybenzoic acid, 2-amino-3-chlorobenzoic acid, methyl 2-amino-4-chlorobenzoate and 4-morpholinopyridine) reported mutagenic were identified in a two system in silico assessment and expert review of the structuresas non-mutagenic. Likely reasons for mutagenicity could not be identified and the purity of the compounds tested was proposed. In the current investigation, the purest available sample of the four compounds was tested in an OECD-compliant Ames test. The compounds were all found to be non-mutagenic. Possible reasons for the discrepancy between previously reported and current results are discussed. Additionally, important points to consider when conducting an expert review of available Ames data are provided particularly in cases where reported Ames results are discrepant with a two system in silico assessment.

    The traditional assessment tools for dementia, such as the MMSE, have only limited ability to follow subjects with severe dementia because they show a floor effect. Specific observational and performance-based instruments were recently developed. To directly compare an observational scale to a performance-based instrument in moderate to severe dementia. We compared a slightly modified version of the performance-based Test for Severe Impairment (mTSI) to the observer-based Bedford Alzheimer Nursing Severity Scale (BANS-S). Both scales were administered, together with the Mini-Mental State Examination (MMSE) and the Clinical Dementia Rating scale (CDR), to a nursing-home sample of 130 women suffering from different types of dementia (CDR range:1-4; MMSE range:0-18), defined according to DSM-IV criteria. Mean age was 86.9 +/- 7.3 years and mean education was 2.7 +/- 1.1 years. The BANS-S could be applied to all patients, the mTSI to 87 subjects (66.9%). Mean mTSI score decreased progressively from CDR stage 2 to CDR stage 4, whereas no difference was detectable between CDR stages 1 and 2. By contrast, the BANS-S was not significantly different for CDR stages 1 to 3, and the mean BANS-S score worsened only in CDR stage 4. Results were similar for AD and non AD dementia. Both scales were independent from age and education and their test-retest and inter-rater reliabilities were satisfactory. The mTSI looks promising in the moderate-to-severe range, whereas the BANS-S seems more useful in the very late stage of dementia. However, neither scale was optimal and additional instruments should be tested in future studies. Copyright (c) 2005 John Wiley & Sons, Ltd.

    Background Ireland introduced a comprehensive workplace smoke-free legislation in March, 2004. Smoking-related adverse birth outcomes have both health care and societal cost implications. The main aim of this study was to determine the impact of the Irish smoke-free legislation on small-for-gestationa- age (SGA) births. Methods and Findings We developed a population-based birthweight (BW) percentile curve based on a recent study to compute SGA (BW <5th percentile) and very SGA (vSGA - BW<3rd percentile) for each gestational week. Monthly births born between January 1999 and December 2008 were analyzed linking with monthly maternal smoking rates from a large referral maternity university hospital. We ran individual control and CUSUM charts, with bootstrap simulations, to pinpoint the breakpoint for the impact of ban implementation ( = April 2004). Monthly SGA rates (%) before and after April 2004 was considered pre and post ban period births, respectively. Autocorrelation was tested using Durbin Watson (DW) statistic. Mixed models using a random intercept and a fixed effect were employed using SAS (v 9.2). A total of 588,997 singleton live-births born between January 1999 and December 2008 were analyzed. vSGA and SGA monthly rates declined from an average of 4.7% to 4.3% and from 6.9% to 6.6% before and after April 2004, respectively. No auto-correlation was detected (DW = ∼2). Adjusted mixed models indicated a significant decline in both vSGA and SGA rates immediately after the ban [(−5.3%; 95% CI −5.43% to −5.17%, p<0.0001) and (−0.45%; 95% CI: −0.7% to −0.19%, p<0.0007)], respectively. Significant gradual effects continued post the ban periods for vSGA and SGA rates, namely, −0.6% (p<0.0001) and −0.02% (p<0.0001), respectively. Conclusions A significant reduction in small-for-gestational birth rates both immediately and sustained over the post-ban period, reinforces the mounting evidence of the positive health effect of a successful

    Testing Summary Pacific Northwest National Laboratory (PNNL) has been tasked by Bechtel National Inc. (BNI) on the River Protection Project-Hanford Tank Waste Treatment and Immobilization Plant (RPP-WTP) project to perform research and development activities to resolve technical issues identified for the Pretreatment Facility (PTF). The Pretreatment Engineering Platform (PEP) was designed and constructed and is to be operated as part of a plan to respond to issue M12, “Undemonstrated Leaching Processes.” The PEP is a 1/4.5-scale test platform designed to simulate the WTP pretreatment caustic leaching, oxidative leaching, ultrafiltration solids concentration, and slurry washing processes. The PEP replicates the WTP leaching processes using prototypic equipment and control strategies. The PEP also includes non-prototypic ancillary equipment to support the core processing. Two operating scenarios are currently being evaluated for the ultrafiltration process (UFP) and leaching operations. The first scenario has caustic leaching performed in the UFP-2 ultrafiltration feed vessels (i.e., vessel UFP-VSL-T02A in the PEP and vessels UFP-VSL-00002A and B in the WTP PTF). The second scenario has caustic leaching conducted in the UFP-1 ultrafiltration feed preparation vessels (i.e., vessels UFP-VSL-T01A and B in the PEP; vessels UFP-VSL-00001A and B in the WTP PTF). In both scenarios, 19-M sodium hydroxide solution (NaOH, caustic) is added to the waste slurry in the vessels to leach solid aluminum compounds (e.g., gibbsite, boehmite). Caustic addition is followed by a heating step that uses direct injection of steam to accelerate the leaching process. Following the caustic leach, the vessel contents are cooled using vessel cooling jackets and/or external heat exchangers. The main difference between the two scenarios is that for leaching in UFP-1, the 19-M NaOH is added to un-concentrated waste slurry (3 to 8 wt% solids), while for leaching in UFP-2, the slurry is

    In response to the dramatic increase in alcohol-related problems in Lithuania, policy measures, including alcohol advertising and availability restrictions combined with taxation increase, were implemented in 2007-08. Simultaneously, a full alcohol advertising ban was adopted to take effect from 1 January 2012. Therefore, the alcohol industry responded with extensive lobbying aiming to revoke this ban, and ultimately they succeeded at the end of December 2011. To document and analyse actions of stakeholders and events during the alcohol advertising ban cancellation process in Lithuania. Policy analysis includes a development of event time-line, description of key stakeholders' actions and a review of policy context. The alcohol industry in Lithuania used similar tactics as the tobacco industry globally, such as creating strong and diverse opposing groups. The industry successfully exerted pressure to change alcohol control legislation, while non-governmental organizations had the important role of a watchdog, blunting industry's efforts. Unequal power distribution made it difficult to withstand combined local and international lobbying to cancel the ban. Given the global nature of the alcohol industry, there is a need for international regulation to limit the influence of vested interests on national lawmaking. © 2014 Society for the Study of Addiction.

    2017-06-01

    To examine state statutes banning powdered alcohol, we identified relevant statutes in all 50 states and the District of Columbia through a search (initial search March 2016; follow-up search November 2016) using the legal research database LexisNexis. To identify the laws, we used the following search terms: "concentrated alcohol," "crystalline alcohol," "granulated alcohol," "palcohol," and "powdered alcohol." As of November 2016, 31 states had statutory bans on powdered alcohol. Statutes in 22 states outline penalties for violating the state's ban on powdered alcohol. Five states include suspension and revocation of alcohol beverage licenses and permits among the penalties. Thirteen states provide exceptions to their ban on powdered alcohol for bona fide scientific research. Twelve states have exceptions for powdered alcohol designed for commercial use or not intended for human consumption. With concerns expressed that powdered alcohol may lead to greater alcohol consumption, particularly among minors, the majority of state legislatures have demonstrated their willingness to restrict access to novel alcohol products to protect the public's health. However, the effectiveness of these laws should be evaluated if the product does become available.

    The Connecticut Conference of the United Church of Christ, which represents the largest Protestant denomination in the state, has passed a resolution affirming an ethical duty to do research on human gene therapy and is planning to form local church groups to study the scientific and ethical issues involved. The resolution is intended to counter an earlier one proposed by Jeremy Rifkin to ban all efforts at engineering specific traits into the human germline. The Rifkin proposal had been endorsed by a large number of religious leaders, including the head of the U.S. United Church of Christ, but was subsequently characterized by many of the church leaders as overly restrictive.

  10. Field testing of a convergent array of acoustic Doppler profilers for high-resolution velocimetry in energetic tidal currents

    Harding, Samuel F.; Sellar, Brian; Richmond, Marshall C.

    2016-04-25

    An array of single-beam acoustic Doppler profilers has been developed for the high resolution measurement of three-dimensional tidal flow velocities and subsequently tested in an energetic tidal site. This configuration has been developed to increase spatial resolution of velocity measurements in comparison to conventional acoustic Doppler profilers (ADPs) which characteristically use divergent acoustic beams emanating from a single instrument. This is achieved using geometrically convergent acoustic beams creating a sample volume at the focal point of 0.03 m3. Away from the focal point, the array is also able to simultaneously reconstruct three-dimensional velocity components in a profile throughout the water column, and is referred to herein as a convergent-beam acoustic Doppler profiler (C-ADP). Mid-depth profiling is achieved through integration of the sensor platform with the operational commercial-scale Alstom 1MW DeepGen-IV Tidal Turbine deployed at the European Marine Energy Center, Orkney Isles, UK. This proof-of-concept paper outlines the C-ADP system configuration and comparison to measurements provided by co-installed reference instrumentation.

  11. Testing the Potential of Vegetation Indices for Land Use/cover Classification Using High Resolution Data

    Karakacan Kuzucu, A.; Bektas Balcik, F.

    2017-11-01

    Accurate and reliable land use/land cover (LULC) information obtained by remote sensing technology is necessary in many applications such as environmental monitoring, agricultural management, urban planning, hydrological applications, soil management, vegetation condition study and suitability analysis. But this information still remains a challenge especially in heterogeneous landscapes covering urban and rural areas due to spectrally similar LULC features. In parallel with technological developments, supplementary data such as satellite-derived spectral indices have begun to be used as additional bands in classification to produce data with high accuracy. The aim of this research is to test the potential of spectral vegetation indices combination with supervised classification methods and to extract reliable LULC information from SPOT 7 multispectral imagery. The Normalized Difference Vegetation Index (NDVI), the Ratio Vegetation Index (RATIO), the Soil Adjusted Vegetation Index (SAVI) were the three vegetation indices used in this study. The classical maximum likelihood classifier (MLC) and support vector machine (SVM) algorithm were applied to classify SPOT 7 image. Catalca is selected region located in the north west of the Istanbul in Turkey, which has complex landscape covering artificial surface, forest and natural area, agricultural field, quarry/mining area, pasture/scrubland and water body. Accuracy assessment of all classified images was performed through overall accuracy and kappa coefficient. The results indicated that the incorporation of these three different vegetation indices decrease the classification accuracy for the MLC and SVM classification. In addition, the maximum likelihood classification slightly outperformed the support vector machine classification approach in both overall accuracy and kappa statistics.

    The future of nano-food largely hinges on public perceptions and willingness to accept this novel technology. The present study utilizes the scientific literacy model and psychometric paradigm as the key theoretical frameworks to examine the factors influencing public support for labeling and banning of nano-food in Singapore. Using data collected from a nationally representative survey of 1001 respondents, the findings demonstrated that attitudes toward technology, preference for natural product, science knowledge, and risk perception were found to substantially affect public support for both labeling and banning of nano-food. Conversely, attention to food safety news on traditional media and attention to nano-news on new media were only associated with public support for labeling of nano-food. Similarly, benefit perception was only significantly associated with public support for banning of nano-food. Theoretically, these findings support the growing body of literature that argues for the significant role played by predispositions, media use, science knowledge, and risk and benefit perceptions on attitude formation toward nano-food. It serves as the pioneering piece to address the aspect of banning in the field of nano-food. Practically, insights drawn from this study could aid relevant stakeholders in enlisting effecting strategies to convey the benefits of nano-food while mitigating the risk perceptions among the public.

    2012-01-01

    Objective: High resolution computed tomography (HRCT) and pulmonary function tests (PFT) are the two main methods, currently used for investigation of pulmonary complications in sulfur mustard gas exposed patients. According to different types of injuries in mustard gas exposed individuals, we decided to test the correlation between PFT and HRCT in these victims. Methodology: Fifty one randomly selected cases from 12000 mustard gas exposed patients during Iran-Iraq war (1983-1989) were studied. HRCT and PFT were conducted based on standard protocols. HRCT scores were tested for correlation to PFT measures. Results: A significant differences between PFT findings were found within HRCT groups (score=3, score 4-6 and score =7). There was a significant correlation between HRCT scores and FEV1, MMEF and FEV1: FVC ratio (P<0.05) in all subjects. Conclusion: HRCT and PFT results showed an acceptable correlation in mustard gas exposed patients. It seems to be useful to use each of these two diagnostic tools based on clinical judgment and feasibility. (author)

    The paper presents the first results from the Front- End Board (FEB) with the biggest Cyclone R V E FPGA 5CEFA9F31I7N, supporting 8 channels sampled up to 250 MSps at 14-bit resolution. Considered sampling for the SD is 120 MSps, however, the FEB has been developed with external anti-aliasing filters to keep a maximal flexibility. Six channels are targeted to the SD, two the rest for other experiments like: Auger Engineering Radio Array and additional muon counters. More channels and higher sampling generate larger size of registered events. We used the standard radio channel for a radio transmission from the detectors to the Central Data Acquisition Station (CDAS) to avoid at present a significant modification of a software in both sides: the detector and the CDAS (planned in a future for a final design). Seven FEBs have been deployed in the test detectors on a dedicated Engineering Array in a hexagon. Several variants of the FPGA code were tested for 120, 160, 200 and even 240 MSps DAQ. Tests confirmed a stability and reliability of the FEB design in real pampas conditions with more than 40 deg. C daily temperature variation and a strong sun exposition with a limited power budget only from a single solar panel. (authors)

    Recent proposals to punish athletes for taking drugs or to impose mandatory drug testing cannot be defended in ethical terms. Nor is it possible to distinguish consistently between ethical and unethical uses of restorative drugs, additive drugs, painkillers, and recreational drugs. We oppose drugs in sports because they violate the majority notion of acceptable behavior. But such opposition has more to do with defending the ideals of the community than with creating policies that are ethically sound.

    Objective sales data have indicated that the Norwegian indoor smoke-free regime implemented in June 2004 did not affect the hospitality business negatively. This paper investigates whether self-reports on the economic impact of the smoking ban from employees in the hospitality sector gave similar results, and whether post-ban self-reports on the economic impact of the ban were influenced by pre-ban attitudes towards smoke-free policies. A random sample of 516 employees in bars and restaurants stated their attitudes towards smoke-free policies shortly before the ban became effective. One year later, the same respondents gave their perceptions of changes in patronage for their workplace. Data were collected using self-administered questionnaires and telephone interviews. 56.4% of the hospitality workers stated that the ban on smoking had led to a large reduction (28.2%) or some reduction (28.2%) in the number of patrons, a result inconsistent with analysis of sales data. After adjusting for demographic and smoking-related variables, a negative pre-ban attitude significantly increased the odds for reporting a negative economic impact post ban (odds ratio 2.48, confidence interval 1.48-4.14). Subjective reports of the economic impact from an indoor ban on smoking are influenced by attitudes towards smoke-free policies and should not be considered as a valid measure of the economic effect.

    Quantitative analysis of high-resolution lava flow morphology can improve our understanding of past effusive eruptions by providing insight into eruptive processes and the rheological properties of erupted magmas. We report the results of an ongoing investigation into the young dacite lava flows of the Kameni islands, Santorini volcano, Greece, which were emplaced during both subaerial and shallow submarine eruptions over the past 3000 years. Historical eruptions of the Kameni islands since 1866 have been very carefully documented in contemporaneous scientific reports. Eruptions since 1573 appear to be time-predictable, with a close relationship between eruption length, the size of extruded lava domes, and the time elapsed since the previous eruption. A new NERC - Airborne Survey and Research Facility LiDAR survey of the Kameni islands was completed in May 2012, using a Leica ALS50 Airborne Laser Scanner mounted on a Dornier 228 aircraft. The topographic surface was mapped at an average point density of 2.1 points per square metre, and covers the entire extent of the youngest subaerial lava flow fields on Santorini. A 2-m DEM derived from the 2012 LiDAR dataset was merged with a 5-m resolution bathymetric grid, based on multibeam surveys carried out by the Hellenic Centre for Marine Research, during cruises in 2001 and 2006, using a SEABEAM 2120 hull-mounted swath system. The resultant grid provides the first high resolution map of both subaerial and submarine historic lava flows emplaced in the centre of the Santorini caldera, and includes several previously unidentified submarine flows and cones. Attribute maps were used to delineate and identify discrete lava flows both onshore and offshore; and morphometric profiles were used to compute accurate volumetric estimates for each of the historic flows, and to determine bulk rheological properties of the lavas, assuming a Bingham rheology. This ongoing work will improve our analysis of the relationship between

    As part of an ongoing effort to increase image reproducibility and fidelity in addition to improving cross-instrument consistency we have developed four separate instrument quality tests to augment the ones previously reported. 1) Objective lens quality 2) Resolution 3) Spectral accuracy of the wavelength information from spectral detectors 4) Spectral Separation tested the accuracy and quality of un-mixing algorithms. To ascertain the usefulness of these tests as well as to determine the current ““state”” of microscopes in use, test specimens and detailed protocols were made available worldwide free-of-charge. 55 laboratories located in 18 countries provided data. Objective lens quality: good with most issues arising from user errors or stage/focus drift, approximately 10% of lenses had aberrations. Resolution: within an average of approximately 25% of theoretical values. Spectral accuracy: excellent, even for low resolution systems. Spectral un-mixing: good, poor data collection was the main cause of low quality data.

    Purpose: To evaluate the prevalence and significance of the pathological effects of cigarette smoking on the lung and the sensitivity of high-resolution CT (HRCT) in the recognition of early smoking-induced lesions in asymptomatic former of current smokers. Materials and methods: We performed a prospective and consecutive analysis of 36 volunteers (16 males, 20 females), 10 non-smokers (3 males, 7 females) and 26 smokers (13 males, 13 females / 17 current smokers; 9 former smokers), all asymptomatic and with normal respiratory flows. These subjects underwent lung function testing and HRCT, after providing written informed consent for the study. The HRCT scans were obtained at three pre-selected levels (aortic arch, tracheal carina and venous hilum). The same scans were obtained in post-expiration phase. At the level of the apical segmental bronchus of the right upper lobe, we measured on the monitor wall thickening, and the total and internal diameters using the techniques reported in literature. Each study was independently evaluated by two radiologists that were blinded to all clinical and functional data: they also evaluated the presence, prevalence and type of emphysema, areas of patchy hyperlucency and oligoemia in the inspiration phase and areas of expiratory air trapping. The extension was evaluated with the visual score method. The data obtained were analysed with the Windows SPSS package for statistical analysis. Results: The two groups (non smokers and smokers) showed significant differences in some functional tests such as FEV1 (p [it

    Noninvasive techniques to assess subclinical spread of nonmelanoma skin cancer (NMSC) may improve surgical precision. High-resolution ultrasound has shown promise in evaluating the extent of NMSC. To determine the accuracy of high-resolution ultrasound to assess the margins of basal cell (BCC) and squamous cell carcinomas (SCC) before Mohs micrographic surgery (MMS). We enrolled 100 patients with invasive SCC or BCC. Before the first stage of MMS, a Mohs surgeon delineated the intended surgical margin. Subsequently, a trained ultrasound technologist independently evaluated disease extent using the EPISCAN I-200 to evaluate tumor extent beyond this margin. The accuracy of high-resolution ultrasound was subsequently tested by comparison with pathology from frozen sections. The test characteristics of the high-resolution ultrasound were sensitivity=32%, specificity=88%, positive predictive value=47%, and negative predictive value=79%. Subgroup analyses demonstrated better test characteristics for tumors larger than the median (area>1.74 cm(2)). Qualitative analyses showed that high-resolution ultrasound was less likely to identify extension from tumors with subtle areas of extension, such as small foci of dermal invasion from infiltrative SCC and micronodular BCC. High-resolution ultrasound requires additional refinements to improve the preoperative determination of tumor extent before surgical treatment of NMSC.

  4. Welfare impact of a ban on child labor.

    Science.gov (United States)

    Soares, Jorge

    2010-01-01

    This article presents a new rationale for imposing restrictions on child labor. In a standard overlapping generation model where parental altruism results in transfers that children allocate to consumption and education, the Nash-Cournot equilibrium results in suboptimal levels of parental transfers and does not maximize the average level of utility of currently living agents. A ban on child labor decreases children's income and generates an increase in parental transfers bringing their levels closer to the optimum, raising children's welfare as well as average welfare in the short run and in the long run. Moreover, the inability to work allows children to allocate more time to education, and it leads to an increase in human capital. Besides, to increase transfers, parents decrease savings and hence physical capital accumulation. When prices are flexible, these effects diminish the positive welfare impact of the ban on child labor.

    Ban Huang oral liquid was developed as a veterinary compound preparation by the Lanzhou Institute of Husbandry and Pharmaceutical Sciences of the Chinese Academy of Agricultural Sciences (CAAS). The purpose of this study was to determine whether the oral liquid preparation of traditional Chinese medicine, Ban Huang, is safe and effective for treating respiratory diseases in cattle. Acute oral toxicity experiments were conducted in Wistar rats and Kunming mice via oral administration. The minimum inhibitory concentration of the drug against Mycoplasma bovis in vitro with the double dilution method was 500 mg/mL, indicating good sensitivity. The results of laboratory pathogen testing, analysis of clinical symptoms, and analysis of pathological anatomy were combined to diagnose bovine respiratory diseases in 147 Simmental cattle caused by mixed infections of M. bovis , bovine respiratory syncytial virus, bovine parainfluenza virus type 3, and Mannheimia haemolytica . These cattle were randomly divided into three groups: drug treatment group 1 (treated via Tilmicosin injection), drug treatment group 2 (treated with Shuang Huang Lian oral liquid combined with Tilmicosin injection), and drug treatment group 3 (treated with Ban Huang oral liquid combined with Tilmicosin injection). Treatment effects were observed within 7 days. The results showed no toxicity and a maximum tolerated dose greater than 20 g/kg BW. For the 87 cattle in drug-treatment group, the cure rate was 90.80%, whereas the response rate was 94.25%. The cure rate of drug treatment group was increased by 14.13% in comparison with that of drug control group 1 and by 7.47% in comparison with that of drug control group 2 (both P bovine respiratory diseases, especially for mixed infection caused by M. bovis , bacteria, and viruses.

  6. The impact of tobacco advertising bans on consumption in developing countries.

    2008-07-01

    Tobacco advertising bans have become commonplace in developed nations but are less prevalent in developing countries. The importance of advertising bans as part of comprehensive tobacco control strategies has been emphasised by the Framework Convention on Tobacco Control which calls for comprehensive bans on tobacco advertising. The empirical literature suggests that comprehensive advertising bans have played a role in reducing consumption in developed countries but that limited policies have not. This paper extends this analysis to include 30 developing countries and finds that bans do play an important role in reducing tobacco consumption in these countries. It finds that both comprehensive as well as limited policies are effective in reducing consumption although comprehensive bans have a far greater impact than limited ones. Furthermore, it finds that advertising bans may be even more effective in the developing world than they are in the developed world.

  12. Why ban the sale of cigarettes? The case for abolition.

    Science.gov (United States)

    Proctor, Robert N

    2013-05-01

    The cigarette is the deadliest artefact in the history of human civilisation. Most of the richer countries of the globe, however, are making progress in reducing both smoking rates and overall consumption. Many different methods have been proposed to steepen this downward slope, including increased taxation, bans on advertising, promotion of cessation, and expansion of smoke-free spaces. One option that deserves more attention is the enactment of local or national bans on the sale of cigarettes. There are precedents: 15 US states enacted bans on the sale of cigarettes from 1890 to 1927, for instance, and such laws are still fully within the power of local communities and state governments. Apart from reducing human suffering, abolishing the sale of cigarettes would result in savings in the realm of healthcare costs, increased labour productivity, lessened harms from fires, reduced consumption of scarce physical resources, and a smaller global carbon footprint. Abolition would also put a halt to one of the principal sources of corruption in modern civilisation, and would effectively eliminate one of the historical forces behind global warming denial and environmental obfuscation. The primary reason for abolition, however, is that smokers themselves dislike the fact they smoke. Smoking is not a recreational drug, and abolishing cigarettes would therefore enlarge rather than restrict human liberties. Abolition would also help cigarette makers fulfil their repeated promises to 'cease production' if cigarettes were ever found to be causing harm.

    Purpose: To assess the presence and extent of air trapping (AT) on chest high-resolution CT (HRCT) in sarcoidosis and to correlate such findings with patterns, lesion extent on inspiratory CT and pulmonary function tests (PFT). Material and Methods: Thirty patients with sarcoidosis underwent inspiratory and expiratory HRCT and PFT. HRCT images were evaluated for presence, distribution and AT extent as well as the predominant HRCT pattern and the extent of lesions at inspiration. Attenuation difference in the AT regions at expiration and at inspiration were calculated. The presence and extent of AT were correlated with PFT, extent of involvement and predominant inspiratory patterns. Results: AT was present in 25/30 patients with no lung zone predilection. AT was the only CT indication of pulmonary sarcoidosis in 3/30 patients who also had normal PFT. Attenuation difference between inspiration and expiration ranged from -40 HU to 106 HU. In 2 patients, a paradoxical decrease of lung attenuation was observed at expiration. A significant correlation was found between AT extent at expiration, with residual volume-total lung capacity ratio and residual volume. Conclusion: AT is an additional HRCT finding in sarcoidosis. AT may involve any lung zone, including costophrenic angles and may be the only CT feature of pulmonary sarcoidosis. Strong correlation is only found with PFT values that are specific for incomplete lung emptying at expiration

    New methods are needed in microsystems technology for evaluating microelectromechanical systems (MEMS) because of their reduced size. The assessment and characterization of mechanical and structural relations of MEMS are essential to assure the long-term functioning of devices, and have a significant impact on design and fabrication. Within this study a concept for the investigation of mechanically loaded MEMS materials on an atomic level is introduced, combining high-resolution X-ray diffraction (HRXRD) measurements with finite element analysis (FEA) and mechanical testing. In situ HRXRD measurements were performed on tensile loaded single crystal silicon (SCSi) specimens by means of profile scans and reciprocal space mapping (RSM) on symmetrical (004) and (440) reflections. A comprehensive evaluation of the rather complex XRD patterns and features was enabled by the correlation of measured with simulated, 'theoretical' patterns. Latter were calculated by a specifically developed, simple and fast approach on the basis of continuum mechanical relations. Qualitative and quantitative analysis confirmed the admissibility and accuracy of the presented method. In this context [001] Poisson's ratio was determined providing an error of less than 1.5% with respect to analytical prediction. Consequently, the introduced procedure contributes to further going investigations of weak scattering being related to strain and defects in crystalline structures and therefore supports investigations on materials and devices failure mechanisms.

    Modelling the empirical relationships between habitat quality and species distribution patterns is the first step to understanding human impacts on biodiversity. It is important to build on this understanding to develop a broader conceptual appreciation of the influence of surrounding landscape structure on local habitat quality, across multiple spatial scales. Traditional models which report that 'habitat amount' in the landscape is sufficient to explain patterns of biodiversity, irrespective of habitat configuration or spatial variation in habitat quality at edges, implicitly treat each unit of habitat as interchangeable and ignore the high degree of interdependence between spatial components of land-use change. Here, we test the contrasting hypothesis, that local habitat units are not interchangeable in their habitat attributes, but are instead dependent on variation in surrounding habitat structure at both patch- and landscape levels. As the statistical approaches needed to implement such hierarchical causal models are observation-intensive, we utilise very high resolution (VHR) Earth Observation (EO) images to rapidly generate fine-grained measures of habitat patch internal heterogeneities over large spatial extents. We use linear mixed-effects models to test whether these remotely-sensed proxies for habitat quality were influenced by surrounding patch or landscape structure. The results demonstrate the significant influence of surrounding patch and landscape context on local habitat quality. They further indicate that such an influence can be direct, when a landscape variable alone influences the habitat structure variable, and/or indirect when the landscape and patch attributes have a conjoined effect on the response variable. We conclude that a substantial degree of interaction among spatial configuration effects is likely to be the norm in determining the ecological consequences of habitat fragmentation, thus corroborating the notion of the spatial context

  16. Why Banning Embedded Sales Commissions Is a Public Policy Issue

    Directory of Open Access Journals (Sweden)

    Henri-Paul Rousseau

    2017-07-01

    Full Text Available Regulatory authorities have consulted on the option of banning embedded sales commissions for Canadian financial advisors. Such an action would create more problems than it would solve. It would have serious ramifications for Canadians’ access to financial advice and raise issues of choice, industry concentration and price transparency for clients seeking advice on investments and retirement. Financial advisors have much greater knowledge of investments than their clients, who rightly expect value from their advisors’ services. Advisors may also face conflicts of interest when they make recommendations about a financial product whose manufacturer might be paying the advisor for selling its products. Banning sales commissions from the manufacturers and having the client pay the advisor directly instead brings its own problems. This is because financial advice is a good with peculiar characteristics. Firstly, financial advice has three fundamental components – the alpha, beta and gamma factors. Together, they define the roles financial advisors play: (alpha asset or portfolio manager, (beta asset allocator (rebalancing a client’s portfolio, and (gamma coach with regard to savings discipline and financial planning. Financial advice has value thanks to the interplay between the three factors. Studies of the issue which have focused on one factor at a time, usually the alpha, produce results that are skewed; however, when studies measure all three factors, the evidence shows that financial advice has significant value, greater than the usual cost charged to clients. Secondly, financial advice is an “experience good”, meaning that clients don’t know ahead of time how good financial advice is until they see how it works out. Assessing the value of financial advice may take many years. Since they can’t immediately measure what they’re paying for, clients with modest incomes or wealth are usually willing only to pay low fees, or not pay

    Full Text Available Although previous studies have provided strong evidence that Chinese individuals are exposed to secondhand smoke (SHS and lack knowledge of its harmful effects, there has not been an in-depth exploration of the variability in exposure and knowledge by geographic region, occupation, and socioeconomic status. The objectives of this study were to examine: (1 the demographic factors associated with the level of knowledge of the harmful effects of smoking; (2 the factors related to implementation of in-home and workplace smoking bans; and (3 geographic differences in being exposed to SHS in government buildings, healthcare facilities, restaurants, public transportations, and schools. We used data from the 2010 Global Adult Tobacco Survey-China. Chi-square tests were used for statistical analysis. The results suggested that among Chinese citizens age 15 years and older, there is poor knowledge of the harmful effects of tobacco, and knowledge varies with region and socioeconomic status. Over three-quarters of the households had no smoking restrictions, and a large percentage of workers reported working in places with no smoking ban. In public places, exposure to SHS was high, particularly in rural areas and in the Southwest. These results suggest Chinese individuals are not well informed of smoking and SHS associated risks and are regularly exposed to SHS at home, work and public places.

    2011-09-01

    Full Text Available Abstract Background Several studies have investigated attitudes to and compliance with smoking bans, but few have been conducted in healthcare settings and none in such a setting in Portugal. Portugal is of particular interest because the current ban is not in line with World Health Organization recommendations for a "100% smoke-free" policy. In November 2007, a Portuguese teaching-hospital surveyed smoking behaviour and tobacco control (TC attitudes before the national ban came into force in January 2008. Methods Questionnaire-based cross-sectional study, including all eligible staff. Sample: 52.9% of the 1, 112 staff; mean age 38.3 ± 9.9 years; 65.9% females. Smoking behaviour and TC attitudes and beliefs were the main outcomes. Bivariable analyses were conducted using chi-squared and MacNemar tests to compare categorical variables and Mann-Whitney tests to compare medians. Multilogistic regression (MLR was performed to identify factors associated with smoking status and TC attitudes. Results Smoking prevalence was 40.5% (95% CI: 33.6-47.4 in males, 23.5% (95% CI: 19.2-27.8 in females (p Conclusions Smoking prevalence was high, especially among the lower socio-economic groups. The findings showed a very high level of support for smoking bans, despite the pro-smoking environment. Most staff reported passive behaviour, despite high SHS exposure. This and the high smoking prevalence may contribute to low compliance with the ban and low participation on smoking cessation activities. Smoking behaviour had greater influence in TC attitudes than health professionals' education. Our study is the first in Portugal to identify potential predictors of non-compliance with the partial smoking ban, further emphasising the need for a 100% smoke-free policy, effective enforcement and public health education to ensure compliance and promote social norm change.

    Since Iceland became the first country to impose a ban on point-of-sale (POS) tobacco product displays in 2001, 20 countries have implemented POS display bans as of 2016. This study examined the effect that POS display bans have on smoking prevalence. Data were sourced from Euromonitor International and the WHO MPOWER package for 2007-2014 from 77 countries worldwide. generalised linear models with country and year fixed effects were estimated to analyse the effect of POS display bans on smoking prevalence. Having a POS display ban reduced overall adult daily smoking, male smoking and female smoking by about 7%, 6% and 9%, respectively. Having a POS display ban is likely to reduce smoking prevalence and generate public health benefits. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    This study compares self-reports on compliance with a workplace smoking ban with on-site inspections of the same workplace, in the Netherlands, to assess the validity of self-reported compliance by employees. A total of 360 companies had participated in the telephone survey (in October and November 2006) and were also visited by inspectors directly after the survey to establish compliance. The sampling frame included companies with 5 or more employees, stratified according to the number of employees and type of economic activity. We calculated the agreement, the under- or overestimation and the predictive values, and explored nonresponse research. The percent agreement on compliance between the two measures was 77.5%, the McNemar test was not significant, and the agreement coefficient with first order correction was .68, indicating moderately strong agreement. Furthermore, the results indicate a slight overestimation of compliance. Concerning the predictive values, we found most variance among the self-reported noncompliance: 55.2% of those reporting noncompliance did in fact comply. This study allows to conclude that self-reports on compliance with a workplace smoking ban are largely valid and that social desirability is negligible. For agencies enforcing the workplace smoking ban, these results indicate that a strategy to identify noncompliance among responding companies might be useful. Moreover, such a strategy reduces the burden of inspecting among complying companies.

    Full Text Available Objectives: Electronic cigarette (e-cigarette use is increasing in the U.S. Although marketed as a safer alternative for cigarettes, initial evidence suggests that e-cigarettes may pose a secondhand exposure risk. The current study explored the prevalence and correlates of support for e-cigarette bans. Methods: A sample of 265 current/former smokers completed a cross-sectional telephone survey from June–September 2014; 45% Black, 31% White, 21% Hispanic. Items assessed support for home and workplace bans for cigarettes and e-cigarettes and associated risk perceptions. Results: Most participants were aware of e-cigarettes (99%. Results demonstrated less support for complete e-cigarette bans in homes and workplaces compared to cigarettes. Support for complete e-cigarette bans was strongest among older, higher income, married respondents, and former smokers. Complete e-cigarette bans were most strongly endorsed when perceptions of addictiveness and health risks were high. While both e-cigarette lifetime and never-users strongly supported cigarette smoking bans, endorsement for e-cigarette bans varied by lifetime use and intentions to use e-cigarettes. Conclusions: Support for indoor e-cigarette bans is relatively low among individuals with a smoking history. Support for e-cigarette bans may change as evidence regarding their use emerges. These findings have implications for public health policy.

    Alcohol-related harm in and around licensed venues is associated with substantial costs. Many interventions have been introduced in an effort to combat these harms, and one such intervention is known as patron banning. Patron banning involves prohibiting patrons who have been violent or disorderly in a licensed venue in an attempt to reduce alcohol-related harm. It can be implemented by the venue, by members of police, or by liquor accords. This study aimed to obtain key informant perspectives on the benefits of patron banning as well as on the effectiveness of patron banning in reducing alcohol-related harm. Thirty-six key informants provided perspectives on patron banning through in-depth interviews that were part of a larger study. Key informants were supportive of patron banning for reducing alcohol-related harm, noting that it had many benefits including increased venue safety, general risk management, and deterrence of antisocial behavior. Although processes for banning were not always consistent, identification scanners were generally recognized as a way to ensure that patron banning was enforced. Key informants viewed patron banning as an effective measure for increasing patron safety and reducing alcohol-related harms.

    Most Internet cigarette sales have violated taxation and youth access laws, leading to landmark 2005 agreements with credit card companies, PayPal, and private shippers (United Parcel Service, Federal Express, DHL) to cease participation in these transactions. Despite their promise at the time, loopholes allowed for check payment and U.S. Postal Service (USPS) shipping. This study assessed actual vendor compliance with the payment and shipping bans using a purchase survey. In late 2007 and early 2008, an adult buyer attempted to order cigarettes from the 97 most popular Internet cigarette vendors (ICVs) using banned payment and shipping methods. When banned payment or shipping methods were unavailable, purchases were attempted with alternate methods (e.g., checks, e-checks, USPS). Twenty-seven of 100 orders were placed with (banned) credit cards; 23 were successfully received. Seventy-one orders were placed with checks (60 successfully received). Four orders were delivered using banned shippers; 79 of 83 successfully received orders were delivered by the USPS. About a quarter of ICVs violated the payment ban, others adapted by accepting checks. Most vendors complied with the shipping ban, perhaps because USPS was an easy substitute shipping option. Better enforcement of the bans is needed; the 2009 Prevent All Cigarette Trafficking Act closed the USPS loophole by making cigarettes nonmailable material; evaluation of enforcement efforts and adaptations by vendors are needed. These sorts of bans are a promising approach to controlling the sale of restricted goods online.

    In 2004 the Dutch government instituted a workplace-smoking ban. This study focuses on differences in compliance over time and between occupational sectors, and describes the background variables. Telephone interviews were conducted with company employees across industry, public and service sectors in 2004 (n=705), 2006 (n=2201) and 2008 (n=2034). The questions concerned smoking policy, aspects of awareness and motivation to implement this ban. Compliance rates increased between 2006 (83%) and 2008 (96%) after an initial stagnation in the rate of compliance between 2004 and 2006. The increase in compliance was accompanied by a less negative attitude and an increase in confidence in one's ability to comply (self-efficacy). Differences in compliance between sectors with the highest compliance (public sector) and the lowest compliance (industry) decreased from about 20% to nearly 4%. Simultaneously, in the industry there was a stronger increase for risk perception of enforcement, social influence and self-efficacy. The initial stagnation in increase of compliance might be due to the lack of a (new) coherent package of policy measures to discourage smoking. Over the entire period there was a stronger increase in compliance in the industry sector, probably due to the intensification of enforcement activities and additional policy like legislation, which might increase awareness and social support.

    Tobacco endgame policies are increasingly advocated to end tobacco use. This study investigated public support for a total ban on tobacco sales, use and possession in Hong Kong. A telephone survey was conducted among 1537 randomly selected residents in 2012 to assess their support for a total ban on tobacco sales, usage and possession. Information on sociodemographic characteristics, smoking, and second hand smoke exposure were collected. Logistic regression was used to investigate factors associated with support for a total ban. Most of the never smokers (75.3%), ex-smokers (63.9%), and nearly half of current smokers (48.9%) backed some form of a total ban on tobacco. A total ban on tobacco sales was the most popular option among the three groups, with over half (64.8%) of all respondents supporting a ban within 10 years. Current smoking and higher educational attainment were associated with less support for a total ban on tobacco sales. Among current smokers, having quit intentions and attempts to quit were associated with support for a total ban. A total ban on tobacco sales was supported by most respondents. Ex-smokers and current smokers also voiced substantial support, although less than never smokers. A total ban on tobacco sales before 2022 should be the goal as it is supported by most of the respondents. Interim tobacco control measures, such as tax increases, expansion of smoking cessation services and plain packaging should be implemented to help current smokers quit and reduce smoking initiation before implementation of the ban.

    Tobacco use and the involuntary exposition to secondhand smoke (SHS) is one of the leading causes of cancer. The objective of this study was to assess the effect of the smoke free workplace ban implemented in March of 2007 in Puerto Rico on the exposure of casino workers to secondhand smoke measured in terms of fine particulate matter and cotinine level. This study used a pre-post comparison design to measure exposure to secondhand smoke before (February, 2007) and after (December, 2007 to February, 2008) the workplace smoking ban was implemented. The samples included level of cotinine in saliva from 20 randomly sampled casino union workers and indoor concentrations of fine particulate matter (2.5 microm diameter, PM2.5) in 10 casinos located in the San Juan metropolitan area. Paired t-tests were used to test any statistically significant change in particulate matter and cotinine levels before and after the ban went into effect. The average PM2.5 level in San Juan metropolitan area casinos decreased by 88.5% (95% CI: 63.9%, 96.3%) and the average cotinine level for the sample of nonsmoking casino workers decreased by 52.1% (95% CI: 40.6%, 61.4%). Both reductions were statistically significant (p smoke free workplace ban in 2007 resulted in a significant reduction of the exposure to secondhand smoke to casino workers in the San Juan metropolitan area of Puerto Rico.

    Full Text Available Drug ‘doping’ and the use of banned performance enhancing products (PEPs remains an issue in virtually all competitive sports despite penal consequences and known health risks. The lines distinguishing “fair” and “unfair” performance enhancement have become increasingly blurred. Few studies have explored how attitudes towards legal performance enhancers (drugs/substances, diet, and equipment modifications may influence motivations to use banned PEPs. In the present study, 68 competitive cyclists completed a survey examining the importance of choosing banned and non-banned PEPs using World Anti-Doping Agency (WADA and Union Cycliste Internationale (UCI criteria. Results showed that over 60 percent of cyclists used non-banned PEPs while 8 percent used banned PEPs. Health was overall the most important factor in choosing a PEP while apprehension by a doping agency was least important. Mixed- model ANOVA analyses revealed that motivations to use banned PEPs were complex, as the importance of health, violating the sprit of the sport, performance improvement, and getting caught were differentially influenced by PEP legality (p 0.05. Our findings illustrate the multifactorial nature of PEP use/doping attitudes and highlight the unique role that “legal” performance enhancement may plays in influencing banned and/or unethical sports behaviors.

  18. Trust in Science: CRISPR-Cas9 and the Ban on Human Germline Editing.

    Science.gov (United States)

    Guttinger, Stephan

    2017-06-26

    In 2015 scientists called for a partial ban on genome editing in human germline cells. This call was a response to the rapid development of the CRISPR-Cas9 system, a molecular tool that allows researchers to modify genomic DNA in living organisms with high precision and ease of use. Importantly, the ban was meant to be a trust-building exercise that promises a 'prudent' way forward. The goal of this paper is to analyse whether the ban can deliver on this promise. To do so the focus will be put on the precedent on which the current ban is modelled, namely the Asilomar ban on recombinant DNA technology. The analysis of this case will show (a) that the Asilomar ban was successful because of a specific two-step containment strategy it employed and (b) that this two-step approach is also key to making the current ban work. It will be argued, however, that the Asilomar strategy cannot be transferred to human genome editing and that the current ban therefore fails to deliver on its promise. The paper will close with a reflection on the reasons for this failure and on what can be learned from it about the regulation of novel molecular tools.

    2001-01-01

    When President Bill Clinton attempted to lift the U.S. military's ban on gay and lesbian soldiers, Congress reacted by enacting a law that prohibits known homosexuals from serving in the U.S. armed forces. The official justification for the new policy is the unit cohesion rationale, the notion that if known gays and lesbians were allowed to serve, unit cohesion, performance, readiness and morale would decline. The thesis of this paper is that the evidence that advocates of discrimination invoke to support the plausibility of the unit cohesion rationale does not constitute scientifically valid data. This paper was delivered originally as a lecture at the Commonwealth Club of California and broadcast subsequently on National Public Radio.

  1. Arms Control: US and International efforts to ban biological weapons

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-01

    The Bacteriological (Biological) and Toxin Weapons Convention, the treaty that bans the development, production, and stockpiling and acquisition of biological weapons was opened for signature in 1972 and came into force in 1975 after being ratified by 22 governments, including the depository nations of the USA, the United Kingdom, and the former Soviet Union. In support of the Convention, the USA later established export controls on items used to make biological weapons. Further, in accordance with the 1990 President`s Enhanced Proliferation Control Initiative, actions were taken to redefine and expand US export controls, as well as to encourage multilateral controls through the Australia Group. Thus far, the Convention has not been effective in stopping the development of biological weapons. The principal findings as to the reasons of the failures of the Convention are found to be: the Convention lacks universality, compliance measures are effective, advantage of verification may outweigh disadvantages. Recommendations for mitigating these failures are outlined in this report.

  2. Impact of Denmark's ban on antimicrobials for growth promotion.

    Jensen, Helen H; Hayes, Dermot J

    2014-06-01

    Denmark was among the first countries to ban the use of antimicrobials for growth promotion (AGPs) in animal production through an on-going series of actions and regulations since 1995. In 2010 the Yellow Card scheme was adopted to decrease total antimicrobial consumption in pig production through additional restrictions on pig farmers. The withdrawal of AGPs and other restrictions have reduced total antimicrobial use, but at the same time therapeutic drug use has increased and resistance in key zoonotic bacteria has not decreased. Improved use of vaccines and management practices can help reduce losses especially for weaner pigs, but come with additional costs to producers. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Coughlin, Steven S; Anderson, Jennifer; Smith, Selina A

    2015-01-01

    Secondhand smoke, which is also referred to as environmental tobacco smoke and passive smoke, is a known human carcinogen. Secondhand smoke also causes disease and premature death in nonsmoking adults and children. We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans. To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other countries, have the potential to influence social norms and reduce smoking behavior. Through legislative smoking bans for reducing secondhand smoke exposure and smoking prevalence, opportunities exist to protect the health of Georgians and other Americans and to reduce health care costs. These opportunities include increasing the comprehensiveness of smoking bans in public places and ensuring adequate funding to quit line services.

    2010-04-01

    Despite the national trend that 90% of prisons have smoke-free indoors policies, compliance and enforcement remain barriers to policy success. Key informant interviews about policy compliance and enforcement were conducted with 10 staff and inmates at two North Carolina prison facilities, one with a complete ban (indoors and outdoors) and one with a partial ban (indoors only). Communication of the tobacco bans was consistent and well understood in both facilities. Barriers to compliance and enforcement, especially in the complete ban facility, included policy ''buy in,'' the emerging black market for cigarettes, staff support, and access to nicotine replacement therapy. Despite these barriers, most informants reported that implementation and enforcement of complete bans is possible with adequate communication about the policy and access to cessation therapy.

    2013-06-03

    The objective of this study was to conduct an audit of point-of-sale (POS) tobacco advertising and assess compliance with an advertising ban in a large district of Beirut, Lebanon. The audit was conducted 3 months following the ban on tobacco advertising. Trained students observed all tobacco retail outlets (n = 100) and entered data into a web-based form using iPad(®) technology. Presence of tobacco advertisements was assessed to determine compliance with the national advertising ban. Among the 100 tobacco retail outlets, 62% had tobacco advertisements, including 7% with a tobacco brand logo as part of the main exterior store sign. POS tobacco advertising is widespread in Beirut despite the national advertising ban. These findings point to an urgent need for the enforcement of the advertisement ban with tobacco retail outlets in Lebanon.

  6. A holistic approach to assessing the impact of a smoke-free ban in Romania

    2017-05-01

    Full Text Available A smoke-free ban in full compliance with FCTC recommendations entered into force in Romania as of March 2016, after an intense advocacy effort and with strong argumentation support provided by international tobacco control organizations. The ban has been under heavy challenge from policy-makers and interest groups including a constitutional appeal and two attempts to relax its' provisions. As such, fundamentation of the benefits and direct impact of the smoke-free ban on health, economic and social indicators became a crucial defense pillar. As of September 2016, part of the 2035 Tobacco-Free Romania Initiative project, funded by a grant from Campaign for Tobacco Free Kids, several research polls and studies have been conducted to assess the ban's impact. Subsequent external communication to decision makers and media increased the awareness of the positive impact of the ban and helped adress its' key critical challenge areas.

  7. Insider trading under trading ban regulation in China’s A-share market

    Directory of Open Access Journals (Sweden)

    Chafen Zhu

    2015-09-01

    Full Text Available This study examines the effects of China’s 2008 trading ban regulation on the insider trading of large shareholders in China’s A-share market. It finds no evidence of insider trading during the ban period (one month before the announcement of a financial report, due to high regulation risk. However, the ban only constrains the profitability of insider trades during the ban period, while trades outside it remain highly profitable. Informed insider trading before the ban period is 2.83 times more profitable than uninformed trading. The regulation has changed insider trading patterns, but has been ineffective in preventing insider trading by large shareholders due to rigid administrative supervision and a lack of civil litigation and flexible market monitoring. This study enhances understanding of large shareholders’ trading behavior and has important implications for regulators.

    2014-10-01

    The aim of this study was to examine the effect of a smoking ban on lung function, fractional exhaled nitric oxide, and respiratory symptoms in nonsmoking hospitality workers. Secondhand smoke exposure at the workplace, spirometry, and fractional exhaled nitric oxide were measured in 92 nonsmoking hospitality workers before as well as twice after a smoking ban. At baseline, secondhand smoke-exposed hospitality workers had lung function values significantly below the population average. After the smoking ban, the covariate-adjusted odds ratio for cough was 0.59 (95% confidence interval, 0.36 to 0.93) and for chronic bronchitis 0.75 (95% confidence interval, 0.55 to 1.02) compared with the preban period. The below-average lung function before the smoking ban indicates chronic damages from long-term exposure. Respiratory symptoms such as cough decreased within 12 months after the ban.

  9. The Impact of Smoking Bans on Smoking and Consumer Behavior: Quasi-Experimental Evidence from Switzerland.

    Boes, Stefan; Marti, Joachim; Maclean, Johanna Catherine

    2015-11-01

    In this paper, we exploit the progressive implementation of smoking bans in public venues at the state level in Switzerland to evaluate both the direct effects on smoking and the potential unintended consequences of these legislations on consumer behaviors as measured by visiting restaurants/bars and discos ('going out'). Our results indicate that public venue smoking bans in Switzerland reduce smoking rates, but the findings do not emerge until 1 year following the ban. This pattern of results is consistent with delays in ban enforcement on the part of business owners, difficulties in changing addictive behaviors such as smoking, and/or learning on the part of smokers. We find evidence that smoking bans influence going-out behavior and there is substantial heterogeneity across venue and consumer characteristics. Copyright © 2014 John Wiley & Sons, Ltd.

    2012-01-01

    Full Text Available Purpose. We aimed to clearly visualize heterogeneous distribution of hypoxia-inducible factor 1α (HIF activity in tumor tissues in vivo. Methods. We synthesized of 125I-IPOS, a 125I labeled chimeric protein probe, that would visualize HIF activity. The biodistribution of 125I-IPOS in FM3A tumor-bearing mice was evaluated. Then, the intratumoral localization of this probe was observed by autoradiography, and it was compared with histopathological findings. The distribution of 125I-IPOS in tumors was imaged by a small animal SPECT/CT scanner. The obtained in vivo SPECT-CT fusion images were compared with ex vivo images of excised tumors. Fusion imaging with MRI was also examined. Results. 125I-IPOS well accumulated in FM3A tumors. The intratumoral distribution of 125I-IPOS by autoradiography was quite heterogeneous, and it partially overlapped with that of pimonidazole. High-resolution SPECT-CT fusion images successfully demonstrated the heterogeneity of 125I-IPOS distribution inside tumors. SPECT-MRI fusion images could give more detailed information about the intratumoral distribution of 125I-IPOS. Conclusion. High-resolution SPECT images successfully demonstrated heterogeneous intratumoral distribution of 125I-IPOS. SPECT-CT fusion images, more favorably SPECT-MRI fusion images, would be useful to understand the features of heterogeneous intratumoral expression of HIF activity in vivo.

    Cheelo, Chilala; Nzala, Selestine; Zulu, Joseph M

    2016-10-21

    In 2010 the government of the republic of Zambia stopped training traditional birth attendants and forbade them from conducting home deliveries as they were viewed as contributing to maternal mortality. This study explored positive and negative maternal health related experiences and effects of the ban in a rural district of Kazungula. This was a phenomenological study and data were collected through focus group discussions as well as in-depth interviews with trained traditional birth attendants (tTBAs) and key informant interviews with six female traditional leaders that were selected one from each of the six zones. All 22 trained tTBAs from three clinic catchment areas were included in the study. Content analysis was used to analyse the data after coding it using NVIVO 8 software. Home deliveries have continued despite the community and tTBAs being aware of the ban. The ban has had both negative and positive effects on the community. Positive effects include early detection and management of pregnancy complications, enhanced HIV/AIDS prevention and better management of post-natal conditions, reduced criticisms of tTBAs from the community in case of birth complications, and quick response at health facilities in case of an emergency. Negatives effects of the ban include increased work load on the part of health workers, high cost for lodging at health facilities and traveling to health facilities, as well as tTBAs feeling neglected, loss of respect and recognition by the community. Countries should design their approach to banning tTBAs differently depending on contextual factors. Further, it is important to consider adopting a step wise approach when implementing the ban as the process of banning tTBAs may trigger several negative effects.

  14. Acute respiratory and cardiovascular admissions after a public smoking ban in Geneva, Switzerland.

    Directory of Open Access Journals (Sweden)

    Jean-Paul Humair

    Full Text Available BACKGROUND: Many countries have introduced legislations for public smoking bans to reduce the harmful effects of exposure to tobacco smoke. Smoking bans cause significant reductions in admissions for acute coronary syndromes but their impact on respiratory diseases is unclear. In Geneva, Switzerland, two popular votes led to a stepwise implementation of a state smoking ban in public places, with a temporary suspension. This study evaluated the effect of this smoking ban on hospitalisations for acute respiratory and cardiovascular diseases. METHODS: This before and after intervention study was conducted at the University Hospitals of Geneva, Switzerland, across 4 periods with different smoking legislations. It included 5,345 patients with a first hospitalisation for acute coronary syndrome, ischemic stroke, acute exacerbation of chronic obstructive pulmonary disease, pneumonia and acute asthma. The main outcomes were the incidence rate ratios (IRR of admissions for each diagnosis after the final ban compared to the pre-ban period and adjusted for age, gender, season, influenza epidemic and secular trend. RESULTS: Hospitalisations for acute exacerbation of chronic obstructive pulmonary disease significantly decreased over the 4 periods and were lowest after the final ban (IRR=0.54 [95%CI: 0.42-0.68]. We observed a trend in reduced admissions for acute coronary syndromes (IRR=0.90 [95%CI: 0.80-1.00]. Admissions for ischemic stroke, asthma and pneumonia did not significantly change. CONCLUSIONS: A legislative smoking ban was followed by a strong decrease in hospitalisations for acute exacerbation of chronic obstructive pulmonary disease and a trend for reduced admissions for acute coronary syndrome. Smoking bans are likely to be very beneficial for patients with chronic obstructive pulmonary disease.

  15. Large-sized soda ban as an alternative to soda tax.

    This Note examines New York City's Sugary Drinks Portion Cap Rule (Soda Ban), which was originally set to become effective March 12, 2013. The New York County Supreme Court's decision in New York Statewide Coalition of Hispanic Chambers of Commerce v. New York City Department of Health and Mental Hygiene suspended the Soda Ban on March 11, 2013. The First Department of the Appellate Division of New York State Supreme Court affirmed the suspension on July 30, 2013. However, the complex economic policy and constitutional issues arising from the proposed Soda Ban deserve as much attention as the ultimate result of the legal challenge to the ban. Both courts struck down the Soda Ban on the grounds that it violated the separation of powers doctrine. The lower court further held that the Soda Ban was arbitrary and capricious. This Note does not focus solely on the holdings of the two courts, but takes a broader approach in analyzing the issues involved in the Soda Ban. By comparing and contrasting tobacco products with sugary beverages, this Note explains why the public seems to find the Soda Ban less appealing than tobacco regulations. Specifically, this Note addresses how the failed attempts of numerous states and cities to implement soda taxes demonstrate the complexity of policies geared toward curbing obesity; how fundamental values, such as health, fairness, efficiency, and autonomy factor into obesity policies; and the fact that legislatures and courts are struggling to determine the scope of public health law intervention. The Note explores how the Soda Ban, despite its judicial suspension, could represent a stepping-stone in combating the obesity epidemic.

    Drug 'doping' and the use of banned performance enhancing products (PEPs) remains an issue in virtually all competitive sports despite penal consequences and known health risks. The lines distinguishing "fair" and "unfair" performance enhancement have become increasingly blurred. Few studies have explored how attitudes towards legal performance enhancers (drugs/substances, diet, and equipment modifications) may influence motivations to use banned PEPs. In the present study, 68 competitive cyclists completed a survey examining the importance of choosing banned and non-banned PEPs using World Anti-Doping Agency (WADA) and Union Cycliste Internationale (UCI) criteria. Results showed that over 60 percent of cyclists used non-banned PEPs while 8 percent used banned PEPs. Health was overall the most important factor in choosing a PEP while apprehension by a doping agency was least important. Mixed- model ANOVA analyses revealed that motivations to use banned PEPs were complex, as the importance of health, violating the sprit of the sport, performance improvement, and getting caught were differentially influenced by PEP legality (p PEP use (p PEP use (p > 0.05). Our findings illustrate the multifactorial nature of PEP use/doping attitudes and highlight the unique role that "legal" performance enhancement may plays in influencing banned and/or unethical sports behaviors. Key PointsUse of performance enhancers is high even among non-professional athletesCyclists overall rated "risk to health" as the most important factor in choosing to use a performance enhancing product.Motivations to use banned performance enhancer are complex and are significantly influenced by whether an athlete utilizes "legal" performance enhancers.

    In 2005 the SCC decided that there would be a total smoking ban in all restaurants and satellite cafeterias on the CERN site, except for the designated area in Restaurant No.1. Unfortunately, it seems that this ban is often over-looked, resulting in an unhealthy and unpleasant environment for the users and staff of these facilities. You are asked to respect this ban and are reminded that smoking is only permitted in the room in Restaurant 1 specially installed for this purpose. The CSR Restaurant Monitoring Committee

    A dual-resolution (DR) version of a regional ensemble Kalman filter (EnKF)-3D ensemble variational (3DEnVar) coupled hybrid data assimilation system is implemented as a prototype for the operational Rapid Refresh forecasting system. The DR 3DEnVar system combines a high-resolution (HR) deterministic background forecast with lower-resolution (LR) EnKF ensemble perturbations used for flow-dependent background error covariance to produce a HR analysis. The computational cost is substantially reduced by running the ensemble forecasts and EnKF analyses at LR. The DR 3DEnVar system is tested with 3-h cycles over a 9-day period using a 40/˜13-km grid spacing combination. The HR forecasts from the DR hybrid analyses are compared with forecasts launched from HR Gridpoint Statistical Interpolation (GSI) 3D variational (3DVar) analyses, and single LR hybrid analyses interpolated to the HR grid. With the DR 3DEnVar system, a 90% weight for the ensemble covariance yields the lowest forecast errors and the DR hybrid system clearly outperforms the HR GSI 3DVar. Humidity and wind forecasts are also better than those launched from interpolated LR hybrid analyses, but the temperature forecasts are slightly worse. The humidity forecasts are improved most. For precipitation forecasts, the DR 3DEnVar always outperforms HR GSI 3DVar. It also outperforms the LR 3DEnVar, except for the initial forecast period and lower thresholds.

    A high-resolution three-dimensional Eulerian transport and transformation model has been developed to simulate concentrations of tropospheric sulfate for specific times and locations; it was applied over the North Atlantic and adjacent continental regions during October and November, 1986. The model represents emissions of anthropogenic SO{sub 2} and sulfate and of biogenic sulfur species, horizontal and vertical transport, gas-phase oxidation of SO{sub 2} and dimethylsulfide, aqueous-phase oxidation of SO{sub 2}, and wet and dry deposition of SO{sub 2}, sulfate, and methanesulfonic acid (MSA). The meteorological driver is the 6-hour output from the forecast model of the European Centre for Medium-Range Weather Forecasts. Calculated sulfate concentrations and column burdens, examined in detail for October 15 and October 22 at 6Z, are related to existing weather patterns. These results exhibit rich temporal and spatial structure; the characteristic (1/e) temporal autocorrelation time for the sulfate column burdens over the central North Atlantic averages 20 hours; 95% of the values were 25 hours or less. The characteristic distance of spatial autocorrelation over this region depends on direction and averages 1,600 km; with 10{sup th} percentile value of 400 km and 90{sup th} percentile value of 1,700 km. Daily average model sulfate concentrations at the lowest vertical accurately represent the spatial variability, temporal episodicity, and absolute magnitudes of surface concentrations measured by monitoring stations in Europe, Canada and Barbados.

    This report discusses the influence of defects on the failure behavior of ceramic materials under four-point bending stress. In this connection various Si 3 N 4 and SiC materials with and without artificially introduced defect particles (Fe, WC, Si, pores) were examined by the following non-destructive test methods: photoacoustic microscopy, scanning laser acoustic microscopy, microfocus roentgenoscopy and ultrasound transit-time measurements. Finally, a four-point bending test and a fracture-mechanical evaluation of the fracture-incuding defects were carried out at the Institute for reliability and failure studies in mechanical engineering of the University of Karlsruhe. According to the type of stress the samples predominantly failed in the case of defects in the surface zone of the side in tension. Among the ndt methods applied the photoacoustic microscopy as a typical surface testing method could predict most of the fracture-inducing defects (30-50 %) without causing destruction. In this connection a different detection sensitivity which corresponds to the thermal reflection factors became apparent according to the type of defect. Furthermore the reports describes the results of some preliminary tests on ndt of green ceramics. In these investigations both the microfocus roentgenoscopy test and the roentgen computed tomography showed a high potential of detecting inhomogeneities and defects in green Si 3 N 4 and SiC components.

    Pacific Northwest National Laboratory (PNNL) has been tasked by Bechtel National Inc. (BNI) on the River Protection Project-Hanford Tank Waste Treatment and Immobilization Plant (RPP-WTP) project to perform research and development activities to resolve technical issues identified for the Pretreatment Facility (PTF). The Pretreatment Engineering Platform (PEP) was designed, constructed and operated as part of a plan to respond to issue M12, “Undemonstrated Leaching Processes” of the External Flowsheet Review Team (EFRT) issue response plan.( ) The PEP is a 1/4.5-scale test platform designed to simulate the WTP pretreatment caustic leaching, oxidative leaching, ultrafiltration solids concentration, and slurry washing processes. The PEP replicates the WTP leaching processes using prototypic equipment and control strategies. The PEP also includes non-prototypic ancillary equipment to support the core processing. The work described in this report addresses caustic leaching under WTP conditions, based on tests performed with a Hanford waste simulant. Because gibbsite leaching kinetics are rapid (gibbsite is expected to be dissolved by the time the final leach temperature is reached), boehmite leach kinetics are the main focus of the caustic-leach tests. The tests were completed at the laboratory-scale and in the PEP, which is a 1/4.5-scale mock-up of key PTF process equipment. Two laboratory-scale caustic-leach tests were performed for each of the PEP runs. For each PEP run, unleached slurry was taken from the PEP caustic-leach vessel for one batch and used as feed for both of the corresponding laboratory-scale tests.

    To examine whether the nationwide smoking ban, imposed in 2007, had an impact on the profitability of Belgian restaurants. Objective financial reporting data on 1613 restaurants were analysed with return on assets as the outcome measure. The data were collected from the Belfirst database and cover the period 2004-2009. To assess the impact of the smoking ban, a differences-in-differences estimation method was used, with bars serving as the control group. The regression model was estimated, while controlling for firm-specific characteristics and unobserved firm-level heterogeneity. The variable of interest is the interaction between the smoking ban dummy and the dummy for the treatment group. The coefficient of this variable is insignificant. The adoption of the nationwide smoking ban did not affect the profitability of Belgian restaurants.

    Correlations between mapping units of costal sedimentary basin and interpretation of piezocone test results are presented and discussed based on examples from Caravelas strandplain, (State of Bahia), Paranaguá (State of Paraná) and Guarujá bays (State of São Paulo), Brazil. Recognizing that the sedimentary environment was mainly controlled by sea level fluctuations led to the interpretation of transgressive and regressive sedimentary sequences, which is in a good agreement with the sea level fluctuation curves currently accepted for these regions. The interpretation of piezocone test results shows that the sedimentary sequences of Caravelas and Guarujá sites are similar and they have a good correlation to the sea level fluctuation curve accepted for Salvador region, State of Bahia. On the other hand, the piezocone test results from Paranaguá site indicate a different sedimentary sequence from the previous ones, relating to the sea level fluctuation curve accepted for Paranaguá region. The results show the high applicability of piezocone testing for stratigraphical logging and suggest that it is possible to integrate it with other current techniques used for paleo-environmental studies in Brazil, in accordance with recent approaches used in international research on the subject.

    Australian states have introduced an outright ban on commercial artificial tanning sunbeds. This was based on evidence from systematic reviews affirming a strong association between tanning bed use and increased risk of melanoma. The implementation of the ban provides an opportunity to assess the effectiveness of the legislation in preventing access to artificial UV radiation. Compliance with the ban has been enforced and monitored by government departments. We additionally monitored online tanning bed advertisements before and after the ban, showing a decline over time in the number of sunbeds advertised for sale on gumtree.com.au and ebay.com.au, from a peak of 115 advertisements in May 2014 to 50 or fewer per month from February 2015. There was also an increase in advertised price, with the percentage of sunbeds offered in Victoria on gumtree.com.au at higher than $2 000 increasing from around 25% between January and June 2014 to 65% in the quarter following the introduction of the ban. Advertisements on gumtree.com.au from individuals wishing to access a sunbed in a private home in Victoria increased from only isolated instances in the months immediately prior to the ban, to between 25 and 77 advertisements per month in the quarter following the ban. In summary, the introduction of an outright ban of commercial sunbeds has achieved a dramatic reduction in the availability of harmful artificial UV radiation sources in Australia. Long-term benefits to the health of the population and a reduction in costs to the health system are expected to result. © 2016 British Association of Dermatologists.

    Background: On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Methods: Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Results: Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. Conclusion: The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments. PMID:22294782

    Hospitality workers are a population particularly at risk from the noxious effects of environmental tobacco smoke (ETS). The Canton of Vaud, Switzerland banned smoking in public places in September 2009. This prospective study addresses the impact of the ban on the health of hospitality workers. ETS exposure was evaluated using a passive sampling device that measures airborne nicotine; lung function was assessed by spirometry; health-related quality of life, ETS exposure symptoms and satisfaction were measured by questionnaire. 105 participants (smokers and non-smokers) were recruited initially and 66 were followed up after one year. ETS exposure was significantly lower after the ban. Hospitality workers had lower pre-ban forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) values than expected. FEV1 remained stable after the ban, with a near-significant increase in the subgroup of asthmatics only. FVC increased at one year follow-up from 90.42% to 93.05% (p = 0.02) in the entire cohort; women, non-smokers and older participants gained the greatest benefit. The health survey showed an increase in physical wellbeing after the ban, the greatest benefit being observed in non-smokers. ETS exposure symptoms were less frequent after the ban, especially red and irritated eyes and sneezing. The new law was judged useful and satisfactory by the vast majority of employees, including smokers. The recent cantonal ban on smoking in public places brought about an improvement in lung function, physical well-being and ETS symptoms of hospitality workers, including smokers.

  14. City mayors on the march. Hiroshima leading citizen campaign to ban nuclear weapons

    International Nuclear Information System (INIS)

    Akiba, T.

    2003-01-01

    Led on our tragic experience 58 years ago, Hiroshima has continually called for the abolition of nuclear weapons and the realization of genuine and lasting world peace. Unfortunately, despite our efforts, this planet still bristles with enormous arsenals of nuclear weapons, and today we face an increasingly perilous nuclear crisis. We see States that have nuclear weapons taking more rigid positions regarding disarmament, and non-nuclear-weapon States frightened into seeking their own nuclear bombs. The global Nuclear Non-Proliferation Treaty (NPT). the pivotal international agreement regarding nuclear weapons, is teetering on the brink of collapse. The world's leading superpower, the United States, for example, has refused to sign the Comprehensive Nuclear-Test-Ban Treaty and is resuming research into small nuclear weapons. These steps run contrary to the enshrined commitment of nuclear powers to reduce atomic arsenals and move toward a nuclear-weapon free world. We cannot sit quietly as the world plunges toward unspeakable violence and misery. We must let our leaders know, first and foremost, that we demand immediate freedom from the nuclear threat. Nuclear weapons are heinous, cruel, inhumane weapons that threaten our entire species. In 1996, the International Court of Justice issued an advisory opinion declaring them illegal. At the Meeting of the Preparatory Committee to the 2005 NPT Review Conference held in April 2003 in Geneva the president of the World Conference of Mayors for Peace, a non-governmental organization (NGO) that now has 554 member cities in 107 countries and regions, the following demands, were made: A complete and total ban on all nuclear weapons everywhere; Removal of all nuclear weapons from hair-trigger alert immediately and withdrawal of all nuclear weapons deployed on foreign territory; It is high time for all recognized nuclear-weapon States to join in a multilateral process of nuclear disarmament and for de-facto nuclear-weapon States

    Full Text Available Background: Point-of-sale (POS tobacco advertising has been linked to youth smoking susceptibility and experimental smoking. However, there is limited evidence of the association between POS advertising bans and youth smoking participation. This study aims to examine how such bans are associated with current smoking, daily smoking, and regular smoking (≥1 cigarettes per day participation among youth. Methods: one to two waves (primarily one wave of the Global Youth Tobacco Survey were conducted in 130 countries between 2007 and 2011. These surveys were linked to the WHO “MPOWER” data using country and year identifiers to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans and smoking participation in the past month. Weighted logistic regressions were employed to analyze this association while controlling for age, gender, parents’ smoking status, 6 MPOWER policy scores, and GDP per capita. Results and Conclusions: We find that in countries with POS advertising bans, current smoking (OR = 0.73, p ≤ 0.1, daily smoking (OR = 0.70, p ≤ 0.1, and regular smoking (OR = 0.75, p ≤ 0.05 participation in the past month is significantly lower, suggesting that POS promotion bans can potentially reduce youth smoking. This study provides evidence to support the implementation of POS promotion regulations by the US FDA and implementation of the WHO FCTC guidelines regarding restrictions on tobacco POS promotion.

  16. Banning is not enough: The complexities of oceanic shark management by tuna regional fisheries management organizations

    Directory of Open Access Journals (Sweden)

    Mariana Travassos Tolotti

    2015-07-01

    Full Text Available Recently, declining populations of several pelagic shark species have led to global conservation concerns surrounding this group. As a result, a series of species-specific banning measures have been implemented by Regional Fishery Management Organizations (RFMOs in charge of tuna fisheries, which include retention bans, finning bans and trading bans. There are both positive and negative aspects to most management measures, but generally, the positive aspects outweigh the negatives, ensuring the measure is beneficial to the resource and its users in the long term. Banning measures are a good first step towards the conservation of pelagic shark species, especially since they improve conservation awareness among fishers, managers and the public. Measures that impose total bans, however, can lead to negative impacts that may jeopardize the populations they were intended to protect. The majority of pelagic shark catches are incidental and most sharks die before they reach the vessel or after they are released. The legislation set out by RFMOs only prevents retention but not the actual capture or the mortality that may occur as a result. Managers should be fully aware that the development and implementation of mitigation measures are critical for a more effective conservation strategy.

    Norway passed legislation banning smoking in restaurants, bars and other public spaces in 2004. This study tracks changes in hospitality workers' attitudes towards Norway's ban over three time points, using growth modelling analysis to examine predictors of attitude change. Participants were a national sample of 1525 bar and restaurant workers. Surveys were conducted, by phone or internet, one month before the ban's implementation and at 4 and 12 months thereafter. Exploratory principal components analysis of nine survey items revealed one primary attitude component. A latent growth model was fitted to the data to examine trajectories of attitude change and individual differences in rate of change. Respondents supported the ban before implementation and increased support at 4 months (p=0.021) and again at 12 months (p=0.001). Concern for one's job followed a quadratic trend, increasing at 4 months and decreasing at 12 months (phospitality workers increased their support of the ban over its first year. The strong influence of the within-person variables leads to two primary policy recommendations. First, support should be provided to assist cessation efforts and prevent relapse. Second, informational campaigns should inform hospitality workers about evidence that smoking bans are not economic threats to the industry.

However, there is limited evidence of the association between POS advertising bans and youth smoking participation. This study aims to examine how such bans are associated with current smoking, daily smoking, and regular smoking (≥ 1 cigarettes per day) participation among youth. one to two waves (primarily one wave) of the Global Youth Tobacco Survey were conducted in 130 countries between 2007 and 2011. These surveys were linked to the WHO "MPOWER" data using country and year identifiers to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and smoking participation in the past month. Weighted logistic regressions were employed to analyze this association while controlling for age, gender, parents' smoking status, 6 MPOWER policy scores, and GDP per capita. We find that in countries with POS advertising bans, current smoking (OR = 0.73, p ≤ 0.1), daily smoking (OR = 0.70, p ≤ 0.1), and regular smoking (OR = 0.75, p ≤ 0.05) participation in the past month is significantly lower, suggesting that POS promotion bans can potentially reduce youth smoking. This study provides evidence to support the implementation of POS promotion regulations by the US FDA and implementation of the WHO FCTC guidelines regarding restrictions on tobacco POS promotion.

    To identify banned and discouraged-use ingredients, such as ephedra, 1,3-dimethylamylamine, and beta-methyl-phenylethylamine, in readily available weight loss dietary supplements within a 10-mile radius of Regis University. A list of banned and discouraged-use ingredients was compiled with the use of the Food and Drug Administration (FDA) dietary supplement website which provides information on supplement ingredients that are no longer legal or are advised against owing to adverse event reporting. Investigators visited all retail outlet stores within a 10-mile radius of Regis University in Denver, Colorado. Retail chains were not duplicated and only one of each chain was evaluated. A total of 51 weight loss supplement products from retail stores were found with banned or discouraged-use substances listed on their labels. At least one banned ingredient was found to be listed on the product labels in 17 of the 51 studied supplements (33%). At least one discouraged-use ingredient was found in 46 of the 51 products (90%). Retail outlet stores dedicated to supplements and sports nutrition alone were found to have the greatest number of weight loss supplements that included banned and discouraged-use ingredients. The FDA has taken action to remove some weight loss supplements from the market that contain banned ingredients. Unfortunately, based on the findings of this study, it is evident that products containing these ingredients remain on the market today. Copyright © 2016 American Pharmacists Association®.

    We examine the determinants governing both countries' enactment of smoking bans in public places and their ability to successfully put these bans into effect. Using a large sample (N = 99-184) of low-, middle- and high-income countries, econometric techniques are used to estimate the influence of several variables on cross-national variations in the adoption and compliance of second-hand smoke laws (2010). We find similarities in the determinants of adoption and compliance. Yet more notable are the differences, with several political economy factors which have a statistically significant influence on countries' level of compliance with existing smoke-free laws in public places found not to consistently influence their propensity to adopt bans in the first place. Possible explanations for this discrepancy are that governments are motivated to adopt smoking bans for reasons other than protecting the health of their citizens and that the real costs of smoking bans are predominantly borne at the compliance stage. More effort needs to be made to ensure that governments realize their existing policy commitments through effective enforcement of bans.

    Restriction enzymes have previously shown the ability to cleave DNA substrates with mismatched base(s) in recognition sequences; in this study, Ban I endonuclease demonstrated this same ability. Single base substitutions were introduced, and fragments containing various types of unpaired base(s) (heteroduplex fragments) within the Ban I endonuclease recognition sequence, 5'-G|GPyPuCC-3', were generated. Each of the heteroduplex fragments was treated with Ban I endonuclease and analyzed by denaturing gradient gel electrophoresis. Our results showed that heteroduplex fragments containing mismatched bases at either the first or third position of the Ban I recognition sequence or, because of the symmetrical structure of the sequence, the sixth or fourth position on the opposite strand were cleaved by the enzyme. Furthermore, these cleaved fragments contained at least one strand corresponding to the original Ban I recognition sequence. Fragments with mismatches formed by an A (noncanonical, nc) opposite a purine (canonical, ca) or a T (nc) opposite a pyrimidine (ca) were cleaved more efficiently than other types of mismatched bases. These results may help elucidate the mechanisms by which DNA and protein interact during the process of DNA cleavage by Ban I endonuclease. Copyright © 2017 John Wiley & Sons, Ltd.

  2. A total ban on alcohol advertising: presenting the public health case.

    Evidence from burden of disease and economic costing studies amply indicate that the public health burden from hazardous and harmful use of alcohol in South Africa warrants drastic action. Evidence that banning alcohol advertising is likely to be an effective intervention is reflected in WHO strategy documents on non-communicable diseases and harmful use of alcohol. Studies on young people furthermore support arguments refuting the claim that advertising only influences brand choice. Given the weakness of relying on industry self-regulation, the government is considering legislation to ban alcohol advertising, resulting in heated debate. Tobacco control and studies investigating the effect of alcohol advertising bans on consumption and alcohol-related deaths point to the effectiveness of such action - ideally supplemented by other policy interventions. Arguments against an advertising ban include possible communication sector job losses, but these are likely to have been exaggerated. Banning alcohol advertising will necessitate greater scrutiny of digital media, satellite television and merchandising to reduce the likelihood of subverting the ban.

    Test particle simulations of electron injection by the bursty bulk flows (BBFs) have been done using a test particle tracer code [1], and the output fields of the Lyon-Feddor-Mobarry global magnetohydro- dynamics (MHD) code[2]. The MHD code was run with high resolu- tion (oct resolution), and with specified solar wind conditions so as to reproduce the observed qualitative picture of the BBFs [3]. Test par- ticles were injected so that they interact with earthward propagating BBFs. The result of the simulation shows that electrons are pushed ahead of the BBFs and accelerated into the inner magnetosphere. Once electrons are in the inner magnetosphere they are further energized by drift resonance with the azimuthal electric field. In addition pitch angle scattering of electrons resulting in the violation conservation of the first adiabatic invariant has been observed. The violation of the first adiabatic invariant occurs as electrons cross a weak magnetic field region with a strong gradient of the field perturbed by the BBFs. References 1. Kress, B. T., Hudson,M.

    To determine the utility of HRCT in the diagnosis of chronic airflow obstruction and to correlate the morphologic abnormalities revealed by this modality with functional impairment in patients with chronic airflow obstruction. This study involved 80 patients with chronic airflow obstruction who underwent HRCT and a pulmonary function test. Final clinical diagnosis in these patients was determined by a chest physician on the basis of clinical features, bronchoscopy, pulmonary function test, and HRCT. In order to diagnose and determine the extent of areas of decreased attenuation revealed by HRCT (the CT score), the findings of HRCT were retrospectively reviewed by two radiologists, who reached a consensus. Clinical and HRCT diagnoses were then compared, and the rate of agreement between them was calculated. The relationship between the extent of areas of decreased attenuation revealed by HRCT and by FEV1/FVC was evaluated using Correl's account and Student's unpaired t-test. The agreement rate between clinical and HRCT diagnoses was 77.5% (62/80). The rates for bronchiectasis (88.9%, 24/27), emphysema (93.9%, 31/33), and bronchiolitis obliterans (100%, 6/6) were considerably higher than those for chronic bronchitis and bronchial asthma. The correlation rate between CT score and FEV1/FVC was significant in bronchiectasis (p less than 0.05; r: -0.76) and bronchiolitis obliterans (p less than 0.01; r: -0.66), but not in cases involving emphysema, bronchial asthma, or chronic bronchitis (p greater than 0.05). HRCT is valuable in the diagnosis and prediction of physiologic impairment in patients with bronchiectasis and bronchiolitis obliterans, but has limited value in those with emphysema, chronic bronchitis or asthma.

    Full Text Available Correlations between mapping units of costal sedimentary basin and interpretation of piezocone test results are presented and discussed based on examples from Caravelas strandplain, (State of Bahia, Paranaguá (State of Paraná and Guarujá bays (State of São Paulo, Brazil. Recognizing that the sedimentary environment was mainly controlled by sea level fluctuations led to the interpretation of transgressive and regressive sedimentary sequences, which is in a good agreement with the sea level fluctuation curves currently accepted for these regions. The interpretation of piezocone test results shows that the sedimentary sequences of Caravelas and Guarujá sites are similar and they have a good correlation to the sea level fluctuation curve accepted for Salvador region, State of Bahia. On the other hand, the piezocone test results from Paranaguá site indicate a different sedimentary sequence from the previous ones, relating to the sea level fluctuation curve accepted for Paranaguá region. The results show the high applicability of piezocone testing for stratigraphical logging and suggest that it is possible to integrate it with other current techniques used for paleo-environmental studies in Brazil, in accordance with recent approaches used in international research on the subject.Correlações entre unidades de mapeamento em bacias sedimentares costeiras e a interpretação dos resultados de ensaios de piezocone são apresentadas e discutidas, a partir de exemplos da planície de Caravelas (Estado da Bahia e das baias do Guarujá (Estado de São Paulo e Paranaguá (Estado do Paraná, Brasil. O reconhecimento de que o ambiente de sedimentação foi controlado principalmente pelas flutuações do nível do mar levou a interpretação de seqüências de sedimentos transgressivos e regressivos, que têm um bom ajuste com as curvas de variação do nível do mar aceitas para estas regiões.

    The objective of this study is to determine whether R(-)-methamphetamine inhaled from nasal inhalers produces positive methamphetamine results in currently used urine drug screening procedures and to present a rapid method for distinguishing the optical isomers of methamphetamine. Urine from three subjects inhaling from a Vicks Nasal Inhaler every 20 min for six hours tested positive for methamphetamine by EMIT, Toxilab, TDx, and GC/MS. The chiral derivatizing reagent N-trifluoroacetyl-L-prolyl chloride (L-TPC) was used to form methamphetamine diastereomers allowing rapid identification of each stereoisomer of methamphetamine present in the urine samples. Urine samples positive for amphetamines during routine drug screening were determined to consist of a racemic mixture of methamphetamine. The isomeric composition of methamphetamine present in a urine sample indicates the probable source of the drug.

    The ban of processed animal proteins (PAPs) in feed for farmed animals introduced in 2001 was one of the main EU measures to control the bovine spongiform encephalopathy (BSE) crisis. Currently, microscopy and polymerase chain reaction (PCR), are the official methods for the detection of illegal PAPs in feed. However, the progressive release of the feed ban, recently with the legalization of non-ruminant PAPs for the use in aquaculture, requires the development of alternative methods to determine the species origin and the source (legal or not). Additionally, discussions about the need for quantitative tests came up, particularly if the zero-tolerance-concept is replaced by introducing PAP thresholds. To address this issue, we developed and partially validated a multiplex mass spectrometry-based immunoassay to quantify ruminant specific peptides in vegetal cattle feed. The workflow comprises a new sample preparation procedure based on a tryptic digestion of PAPs in suspension, a subsequent immunoaffinity enrichment of the released peptides and a LC-MS/MS based analysis for peptide quantification using isotope labelled standard peptides. For the very first time, a mass spectrometry-based method is capable of detecting and quantifying illegal PAPs in animal feed over a concentration range of four orders of magnitude with a detection limit in the range of 0.1 % to 1 % (w/w).

    A dielectric logging tool, electromagnetic propagation tool (EPT), was deployed in 2007 in the BPXA-DOE-USGS Mount Elbert Gas Hydrate Stratigraphic Test Well (Mount Elbert Well), North Slope, Alaska. The measured dielectric properties in the Mount Elbert well, combined with density log measurements, result in a vertical high-resolution (cm-scale) estimate of gas hydrate saturation. Two hydrate-bearing sand reservoirs about 20 m thick were identified using the EPT log and exhibited gas-hydrate saturation estimates ranging from 45% to 85%. In hydrate-bearing zones where variation of hole size and oil-based mud invasion are minimal, EPT-based gas hydrate saturation estimates on average agree well with lower vertical resolution estimates from the nuclear magnetic resonance logs; however, saturation and porosity estimates based on EPT logs are not reliable in intervals with substantial variations in borehole diameter and oil-based invasion.EPT log interpretation reveals many thin-bedded layers at various depths, both above and below the thick continuous hydrate occurrences, which range from 30-cm to about 1-m thick. Such thin layers are not indicated in other well logs, or from the visual observation of core, with the exception of the image log recorded by the oil-base microimager. We also observe that EPT dielectric measurements can be used to accurately detect fine-scale changes in lithology and pore fluid properties of hydrate-bearing sediments where variation of hole size is minimal. EPT measurements may thus provide high-resolution in-situ hydrate saturation estimates for comparison and calibration with laboratory analysis. ?? 2010 Elsevier Ltd.

    To assess the impact of the Western Australian tobacco point-of-sale display ban on spontaneous purchase behaviours. Daily adult smokers (n=402) observed purchasing cigarettes were recruited via exit interviews either 2 months before or after the implementation of the display ban. Smokers were asked if they had intended to purchase cigarettes before entering the store to assess spontaneous purchase behaviours. Whether smokers had noticed the displays before their purchase and the extent to which this influenced their purchase decision was also assessed via non-prompting questions. When compared with before the ban, fewer smokers after the ban noticed the displays (27.1% vs 1.1%, p<0.001), fewer reported making spontaneous purchases (28.2% vs 19.8%, p<0.05) and fewer claimed the displays influenced their purchase decisions (free recall 5.0% vs 1.1%, p<0.05; cued recall 22.1% vs 3.8%, p<0.001). Before the ban, spontaneous purchasers were more likely than planned purchasers to suggest the displays influenced their purchase decisions (free recall 9.7% vs 3.2%, p<0.05; cued recall 40.0% vs 17.9%, p<0.01). After the ban, spontaneous purchasers nominating the influence of displays fell substantially (free recall 9.7% vs 5.6%, p=NS; cued recall 40.0% vs 11.1%, p<0.01) as it did for planned purchasers (free recall 3.2% vs 0.0%, p<0.05; cued recall 17.9% vs 2.1%, p<0.01). We observed a 30% reduction in smokers making spontaneous tobacco purchases after implementation of the Western Australian tobacco display ban and between a fivefold and sixfold reduction in the proportion suggesting displays influenced their decision to purchase cigarettes. These data are consistent with previous research suggesting tobacco displays encourage spontaneous purchases and their removal corresponds to reductions in the same.

    Following Cambodia's implementation of the 100% condom use program with enforcement of condom use and STI treatment services for sex workers in 2001, sexually transmitted infection and HIV declined markedly. In 2008, Cambodia implemented a law to ban brothel-based sex work. We reported trends in unprotected vaginal intercourse with sex workers among heterosexual men buying sex before (2003-2008) and after (2009-2012) the brothel ban in Cambodia. We also determined the association of brothel ban with these men's reports of unprotected intercourse with sex workers. In this serial cross-sectional study, we collected yearly behavioural data on random cross-sectional samples of heterosexual men buying sex who attended the only government health centre in Siem Reap for voluntary confidential counselling and testing (VCCT) between 2003 and 2012. We used multivariable Poisson regression analysis on the 10-year data of 976 men to obtain the adjusted prevalence ratio (aPR) of unprotected intercourse in the last 6 months by brothel closure. Men buying sex from non-brothel-based sex workers increased almost 3-fold from 17% in 2007-2008 before brothel closure to 55% in 2011-2012 after brothel closure (p < 0.001). Unprotected intercourse with sex workers in the last week increased significantly from 37% (2003-2004) before brothel closure to 65% (2011-2012) after brothel closure. This increase corresponded closely with the increase in self-reported unprotected intercourse from 35% to 61% by the sex workers (n = 1805) attending the same clinic for VCCT. Brothel closure was associated with an increased risk (aPR: 1.65; 95% CI: 1.40-1.94) of unprotected intercourse with sex workers. HIV prevalence in the heterosexual men declined significantly from 26% in 2003-2004 to 4.8% in 2007-2008 and 0 case in 2009-2010 before increasing to 5.6% in 2011-2012. Our findings suggest that the brothel ban had led to an increase in unprotected intercourse with all sex workers for men buying

    the grain boundaries. The glide model incorporates a slip resistance evolution model that characterizes the solute-drag creep effects and can capture well the stress-strain and stress time response of fatigue and creep-fatigue tests at various strain ranges and hold times. In order to accurately capture the creep strains that accumulate particularly at relatively low stress levels, a dislocation climb model has been incorporated into the crystal plasticity modeling framework. The dislocation climb model parameters are calibrated and verified through experimental creep tests performed at 950°. In addition, a cohesive zone model has been fully implemented in the context of the crystal plasticity finite element model to capture the intergranular creep damage. The parameters of the cohesive zone model have been calibrated using available experimental data. The numerical simulations illustrate the capability of the proposed model in capturing damage initiation and growth under creep loads as compared to the experimental observations. The microscale analysis sheds light on the crack initiation sites and propagation patterns within the microstructure. The model is also utilized to investigate the hybrid-controlled creep-fatigue tests and has been found to capture reasonably well the stress-strain response with different hold times and hold stress magnitudes.

    We designed and built two high resolution (0.6-0.55mm special resolution [1.1-1.2mm separation]) thermometry arrays prototypes out of the Allen Bradley 90-120 ohm 1/8 watt resistor to measure surface temperature profiles on SRF cavities. One array was designed to be physically flexible and conform to any location on a SRF cavity; the other was modeled after the common G-10/stycast 2850 thermometer and designed to fit on the equator of an ILC (Tesla 1.3GHz) SRF cavity. We will discuss the advantages and disadvantages of each array and their construction. In addition we will present a case study of the arrays performance on a real SRF cavity TB9NR001. TB9NR001 presented a unique opportunity to test the performance of each array as it contained a dual (4mm separation) cat eye defect which conventional methods such as OST (Oscillating Superleak second-sound Transducers) and full coverage thermometry mapping were unable to distinguish between. We will discuss the new arrays ability to distinguish between the two defects and their preheating performance.

  13. Non-destructive testing of layer-to-layer fusion of a 3D print using ultrahigh resolution optical coherence tomography

    Within the last decade, 3D printing has moved from a costly approach of building mechanical items to the present state-of-the-art phase where access to 3D printers is now common, both in industry and in private places. The plastic printers are the most common type of 3D printers providing prints that are light, robust and of lower cost. The robustness of the structure printed is only maintained if each layer printed is properly fused to its previously printed layers. In situations where the printed component has to accomplish a key mechanical role there is a need to characterize its mechanical strength. This may only be revealed by in-depth testing in order to discover unwanted air-gaps in the structure. Optical coherence tomography (OCT) is an in-depth imaging method, that is sensitive to variations in the refractive index and therefore can resolve with high resolution translucid samples. We report on volume imaging of a 3D printed block made with 100% PLA fill. By employing ultrahigh resolution OCT (UHR-OCT) we show that some parts of the PLA volume reveal highly scattering interfaces which likely correspond to transitions from one layer to another. In doing so, we document that UHR-OCT can act as a powerful tool that can be used in detecting fractures between layers stemming from insufficient fusion between printed structure layers. UHR-OCT can therefore serve as an useful assessment method of quality of 3D prints.

    Although the use of nutritional supplements by adult athletes has been extensively studied, information on supplements consumption by adolescent athletes is still limited. The present study reports on the use of nutritional supplements contaminated with banned doping substances among 170 recreational adolescent athletes from eleven, randomly selected, gym centres, in Athens, Greece. Nutritional supplements consumption was reported by almost 60% of the study population, with proteins/amino acids and vitamins being the most popular. Nine per cent of the users were found to consume nutritional supplements contaminated with anabolic steroids, prohormones, selective androgen receptor modulators (SARMs) and aromatase inhibitors, all pharmacological substances with endocrine modulating properties not stated on the label. None of these individuals had previously consulted a physician or a nutritionist. A representative sample (ca 15%) of the protein/aminoacids and creatine preparations used by the study population were also tested and found free from doping substances. The majority (63%) of adolescents purchased products from the internet. In conclusion, exercising adolescents can have easy access to contaminated nutritional supplements and "black market" products, which could constitute a risk for public health. Low level of awareness and low involvement of medical care professionals among recreational adolescent athletes is also observed. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Although increasing numbers of countries are implementing outdoor school ground smoking bans at secondary schools, less attention is paid to the post-implementation period even though sustainability of a policy is essential for long-term effectiveness. Therefore, this study assesses the level of sustainability and examines perceived barriers/facilitators related to the sustainability of an outdoor school ground smoking ban at secondary schools. A mixed-method design was used with a sequential explanatory approach. In phase I, 438 online surveys were conducted and in phase II, 15 semi-structured interviews were obtained from directors of relevant schools. ANOVA (phase I) and a thematic approach (phase II) were used to analyze data. Level of sustainability of an outdoor school ground smoking ban was high at the 48% Dutch schools with an outdoor smoking ban. Furthermore, school size was significantly associated with sustainability. The perceived barriers/facilitators fell into three categories: (i) smoking ban implementation factors (side-effects, enforcement, communication, guidelines and collaboration), (ii) school factors (physical environment, school culture, education type and school policy) and (iii) community environment factors (legislation and social environment). Internationally, the spread of outdoor school ground smoking bans could be further promoted. Once implemented, the ban has become 'normal' practice and investments tend to endure. Moreover, involvement of all staff is important for sustainability as they function as role models, have an interrelationship with students, and share responsibility for enforcement. These findings are promising for the sustainability of future tobacco control initiatives to further protect against the morbidity/mortality associated with smoking. © The Author 2017.

    Callinan, Joanne E

    2010-01-01

    BACKGROUND: Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and smoking behaviour of those populations they affect. OBJECTIVES: To assess the extent to which legislation-based smoking bans or restrictions reduce exposure to SHS, help people who smoke to reduce tobacco consumption or lower smoking prevalence and affect the health of those in areas which have a ban or restriction in place. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL, Conference Paper Index, and reference lists and bibliographies of included studies. We also checked websites of various organisations. Date of most recent search; July 1st 2009. SELECTION CRITERIA: We considered studies that reported legislative smoking bans and restrictions affecting populations. The minimum standard was having a ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. We included randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before and after studies, interrupted-time series as defined by the Cochrane Effective Practice and Organization of Care Group, and uncontrolled pre- and post-ban data. DATA COLLECTION AND ANALYSIS: Characteristics and content of the interventions, participants, outcomes and methods of the included studies were extracted by one author and checked by a second. Because of heterogeneity in the design and content of the studies, we did not attempt a meta-analysis. We evaluated the studies using qualitative narrative synthesis. MAIN RESULTS: There were 50 studies included in this review. Thirty-one studies reported exposure to secondhand smoke (SHS) with 19 studies measuring it using biomarkers. There was

  19. The Asbestos Ban in Korea from a Grassroots Perspective: Why Did It Occur?

    Full Text Available In 2009, asbestos was finally banned in Korea, about 70 years after the first opening of asbestos mines under Japanese control. After having presented the history of asbestos industry, together with its regulations and health effects over time, we constructed narrative analyses of how the asbestos issue under the prevailing risk system was managed by whom and for what purpose, to provide context for the change. We could identify five different phases: laissez-faire, politico-technical, economic–managerial, health-oriented cultural, and human rights-based post-cultural risk systems. The changes leading to the asbestos ban evolved over different phases, and each phase change was necessary to reach the final ban, in that, without resolving the previous issues by examining different categories of potential alternatives, either the final ban was not possible or, even if instituted, could not be sustained. An asbestos ban could be introduced when all the alternatives to these issues, including legitimate political windows, economic rationalizations, health risk protections, and human rights sensitivities, were available. We think the alternatives that we had were not in perfect shape, but in more or less loosely connected forms, and hence we had to know how to build solidarities between different stakeholders to compensate for the imperfections.

    Individuals may compensate for workplace smoking bans by smoking more before or after work, or escaping bans to smoke, but no studies have conducted a detailed, quantitative analysis of such compensatory behaviors using real-time data. 124 daily smokers documented smoking occasions over 3weeks using ecological momentary assessment (EMA), and provided information on real-world exposure to smoking restrictions and type of workplace smoking policy (full, partial, or no bans). Mixed modeling and generalized estimating equations assessed effects of time of day, weekday (vs weekend), and workplace policy on mean cigarettes per hour (CPH) and reports of changing location to smoke. Individuals were most likely to change locations to smoke during business hours, regardless of work policy, and frequency of EMA reports of restrictions at work was associated with increased likelihood of changing locations to smoke (OR=1.11, 95% CI 1.05-1.16; pbusiness hours across weekdays and weekends. Smokers largely compensate for exposure to workplace smoking bans by escaping restrictions during business hours. Better understanding the effects of smoking bans on smoking behavior may help to improve their effectiveness and yield insights into determinants of smoking in more restrictive environments.

    Thailand is internationally renowned for its stringent tobacco control measures. In Thailand, a regulation banning smoking in air-conditioned hotel lobbies was issued in late 2006, causing substantial apprehension within the hospitality industry. A survey of tourists' attitudes toward the ban was conducted. A cross-sectional survey of 5550 travellers staying in various hotels in Bangkok, Surat Thani, Phuket, Krabi and Songkhla provinces, October 2005 to December 2006. Travellers aged 15 years or older with a check-in duration of at least one day and willing to complete the questionnaire were requested by hotel staff to fill in the 5-minute questionnaire at check-in or later at their convenience. Secondhand cigarette smoke was recognised as harmful to health by 89.7% of respondents. 47.8% of travellers were aware of the Thai regulation banning smoking in air-conditioned restaurants. 80.9% of the respondents agreed with the ban, particularly female non-smokers. 38.6% of survey respondents indicated that they would be more likely to visit Thailand again because of the regulation, 53.4% that the regulation would not affect their decision and 7.9% that they would be less likely to visit Thailand again. Banning smoking in air-conditioned hotel lobbies in Thailand is widely supported by tourists. Enforcement of the regulation is more likely to attract tourists than dissuade them from holidaying in Thailand.

    The European Commission's new health strategy for improving health at the European Union (EU) level includes tackling alcohol consumption. This study aimed to assess the prevalence of alcohol consumption and problem drinking, as well as students' attitudes towards banning the sale of alcohol on campus. In total, 5826 students from universities in seven European countries (Denmark, Germany, Spain, Lithuania, Poland, Bulgaria and Turkey) took part in this cross-sectional study. A self-administered questionnaire assessed sociodemographic information, frequency of alcohol consumption, problem drinking and attitudes towards banning the sale of alcohol on campus. The highest prevalence of drinking alcohol more than once per week was reported in Bulgarian (males 46%, females 64%) and Spanish students (males 59%, females 64%). Among those students who drank alcohol (n=3170), problem drinking (CAGE score >1) was found in 24% of males and 13% of females. Male gender, depressive moods and a low importance of good grades at university were risk factors for drinking alcohol more than once per week as well as for problem drinking. There were substantial country differences in the proportion of students who would support a ban of alcohol sales on campus (23% in Denmark, 88% in Poland). Support for a ban was higher among female students and among students who drank alcohol once or less per week. Problem drinking is a concern among students in many European countries, especially among males. Students' support for banning the sale of alcohol on campus varies between countries and should be considered in developing EU policy.

    Background Secondhand smoke, which is also referred to as environmental tobacco smoke and passive smoke, is a known human carcinogen. Secondhand smoke also causes disease and premature death in nonsmoking adults and children. Methods We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans. Results To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other countries, have the potential to influence social norms and reduce smoking behavior. Conclusions Through legislative smoking bans for reducing secondhand smoke exposure and smoking prevalence, opportunities exist to protect the health of Georgians and other Americans and to reduce health care costs. These opportunities include increasing the comprehensiveness of smoking bans in public places and ensuring adequate funding to quit line services. PMID:26345719

    The aim of this paper is to report compliance with the smoking ban and the spread of smoke-free homes after 3-8 years since the Italian smoking ban implementation, according to the ongoing Italian surveillance system for behavioural risk factors (PASSI). PASSI is based on representative annual samples of the Italian population aged 18-69 years. We considered questions on smoking habits, self-reported compliance with the ban, and on smoke-free homes of 176,236 interviews conducted in 2008-2012. Ninety percent of respondents in 2012 reported that the smoking ban was enforced in hospitality premises (HPs), with a significant 3% increase from 2008. Similarly, 91.3% in 2012 reported a high compliance in workplaces other than HPs, with a significant 5% increase. Perception of compliance did not change among smokers and non-smokers. Seventy-eight percent of respondents in 2012 reported smoke-free homes, with a significant increase from 2008 to 2012. The high compliance with the ban that is still increasing even after 8 years since its implementation may partially have caused the concurrent increase in smoke-free homes.

    To investigate the awareness and use of banned pesticides among vegetable greenhouse farmers in a town of Ledu County, Qinghai Province, China and to provide a basis for the management and control of banned pesticides. Local residents who lived in a town of Ledu County for more than 5 years were selected as subjects in August 2012. A questionnaire survey was conducted in 267 vegetable greenhouse farmers who were selected from five villages of the town by cluster random sampling. Of the 267 subjects, 249 (93.26%) completed and returned the questionnaires. Eighty-seven (34.9%) of the 249 subjects were aware of banned pesticides, and the banned pesticide awareness rate varied significantly among the subjects with different education levels (χ(2) = 11.061, P = 0.011). Only education level entered the regression equation in non-conditional logistic regression analysis. Only five (2.0%) of the 249 subjects knew the banned pesticides as well as the details. All the 249 subjects used banned pesticides to varying degrees in the past 5 years. Only 9.0% (17/189) of the vegetable greenhouse farmers knew the time pesticides were initially banned in China. The banned pesticide awareness rate is relatively low in the town of Ledu County, and this rate is influenced by education level. It is needed to spread the knowledge and hazards of banned pesticides.

    With an objective to develop a coal gas manufacturing system for fuel cells, research and development has been performed on a oxygen-blown coal gasifier and researches on a technology to purify gases for fuel cells. This paper summarizes the achievements in fiscal 1999. The current fiscal year has performed, among other the pilot plant construction works, execution of the above-the-ground constructions for the operation center and compressor room building, construction of the cooling water tanks, and partial improvement of roads in the plant site. In the gasifier facilities, items of equipment were fabricated, some of the outsourced articles were procured, and the installations thereof were carried out. For the gas purifying equipment, installation of the gas analyzer room was executed. In the trial run design, discussions were given on the systematic improvements in the test items, the gas sampling procedures, the unit protecting interlock, and the facility protecting logic. For the trial run design, establishment has been implemented on the efficient and functional test plans by establishing priority on the tests to be executed, so that the development items demanded in the pilot test and research can be achieved within the limited test processes.

  8. Resolution and super-resolution.

    Many papers have claimed the attainment of super-resolution, i.e. resolution beyond that achieved classically, by measurement of the profile of a feature in the image. We argue that measurement of the contrast of the image of a dark bar on a bright background does not give a measure of resolution, but of detection sensitivity. The width of a bar that gives an intensity at the center of the bar of 0.735 that in the bright region (the same ratio as in the Rayleigh resolution criterion) is λ/(13.9×numerical aperture) for the coherent case with central illumination. This figure, which compares with λ/(numerical aperture) for the Abbe resolution limit with central illumination, holds for the classical case, and so is no indication of super-resolution. Theoretical images for two points, two lines, arrays of lines, arrays of bars, and grating objects are compared. These results can be used a reference for experimental results, to determine if super-resolution has indeed been attained. The history of the development of the theory of microscope resolution is outlined. © 2017 Wiley Periodicals, Inc.

    The authors investigated the impact of a complete smoking ban on 349 employees of a cancer treatment center. A questionnaire administered approximately 4 months after the ban was initiated queried smokers on the impact of the ban on their smoking habits, their experience of withdrawal symptoms during the workday, and changes in work habits. A separate questionnaire asked nonsmokers about changes in the work environment. Results showed that few smokers quit while a majority decreased their consumption. Withdrawal symptoms were a problem in less than half the smokers, but those reporting signs of physical dependency on nicotine tended to smoke more before and after work and reported negative changes in work performance. Nonsmokers in general reported positive effects on the work environment.

    Iron ore was mined from the banded iron formations of Goa, India, and transported through the Mandovi and Zuari estuaries for six decades until the ban on mining from September 2012. Here we focus on the environmental magnetic properties of sediments from the catchment area, upstream and downstream of these estuaries, and adjacent shelf during peak mining time. Magnetic susceptibility (χ lf) and saturation isothermal remanent magnetization (SIRM) values of sediments were highest in upstream (catchment area and estuaries), decreased gradually towards downstream (catchment area and estuaries), and were lowest on the adjacent shelf. The χ lf values of the Mandovi estuary were two to fourfold higher than those in the Zuari. The sediments of these two estuaries after the mining ban showed enrichment of older magnetite and sharp decrease in the SIRM values. Although the input of ore material has been reduced after mining ban, more flushing of estuarine sediments is required for healthier environment.

  11. The cigarette advertising broadcast ban and magazine coverage of smoking and health.

    At the time of the cigarette broadcast advertising ban, which took effect in 1971, cigarette manufacturers rapidly shifted advertising expenditures from the broadcast media to the print media. In the last year of broadcast advertising and the first year of the ban, cigarette ad expenditures in a sample of major national magazines increased by 49 and then 131 percent in constant dollars. From an 11-year period preceding the ban to an 11-year period following it, these magazines decreased their coverage of smoking and health by 65 percent, an amount that is statistically significantly greater than decreases found in magazines that did not carry cigarette ads and in two major newspapers. This finding adds to evidence that media dependent on cigarette advertising have restricted their coverage of smoking and health. This may have significant implications for public health, as well as raising obvious concerns about the integrity of the profession of journalism.

    The ability to measure metallicities and α-element abundances in individual red giant branch (RGB) stars using medium-resolution spectra (R ≈ 6000) is a valuable tool for deciphering the nature of Milky Way dwarf satellites and the history of the Galactic halo. Extending such studies to more distant systems like Andromeda is beyond the ability of the current generation of telescopes, but by co-adding the spectra of similar stars, we can attain the necessary signal-to-noise ratio (S/N) to make detailed abundance measurements. In this paper, we present a method to determine metallicities and α-element abundances using the co-addition of medium-resolution spectra. We test the method of spectral co-addition using high-S/N spectra of more than 1300 RGB stars from Milky Way globular clusters and dwarf spheroidal galaxies obtained with the Keck II telescope/DEIMOS spectrograph. We group similar stars using photometric criteria and compare the weighted ensemble average abundances ([Fe/H], [Mg/Fe], [Si/Fe], [Ca/Fe], and [Ti/Fe]) of individual stars in each group with the measurements made on the corresponding co-added spectrum. We find a high level of agreement between the two methods, which permits us to apply this co-added spectra technique to more distant RGB stars, like stars in the M31 satellite galaxies. This paper outlines our spectral co-addition and abundance measurement methodology and describes the potential biases in making these measurements.

    Part 1 of this series presented a Monte Carlo Bayesian method for constraining a complex statistical model of global circulation model (GCM) sub-gridcolumn moisture variability using high-resolution Moderate Resolution Imaging Spectroradiometer (MODIS) cloud data, thereby permitting parameter estimation and cloud data assimilation for large-scale models. This article performs some basic testing of this new approach, verifying that it does indeed reduce mean and standard deviation biases significantly with respect to the assimilated MODIS cloud optical depth, brightness temperature and cloud-top pressure and that it also improves the simulated rotational-Raman scattering cloud optical centroid pressure (OCP) against independent (non-assimilated) retrievals from the Ozone Monitoring Instrument (OMI). Of particular interest, the Monte Carlo method does show skill in the especially difficult case where the background state is clear but cloudy observations exist. In traditional linearized data assimilation methods, a subsaturated background cannot produce clouds via any infinitesimal equilibrium perturbation, but the Monte Carlo approach allows non-gradient-based jumps into regions of non-zero cloud probability. In the example provided, the method is able to restore marine stratocumulus near the Californian coast, where the background state has a clear swath. This article also examines a number of algorithmic and physical sensitivities of the new method and provides guidance for its cost-effective implementation. One obvious difficulty for the method, and other cloud data assimilation methods as well, is the lack of information content in passive-radiometer-retrieved cloud observables on cloud vertical structure, beyond cloud-top pressure and optical thickness, thus necessitating strong dependence on the background vertical moisture structure. It is found that a simple flow-dependent correlation modification from Riishojgaard provides some help in this respect, by

    Position emission tomography (PET) imaging using [ 18 F]-setoperone to quantify cortical 5-HT 2A receptors has the potential to inform pharmacological treatments for geriatric depression and dementia. Prior reports indicate a significant normal aging effect on serotonin 5HT 2A receptor (5HT 2A R) binding potential. The purpose of this study was to assess the test-retest variability of [ 18 F]-setoperone PET with a high resolution scanner (HRRT) for measuring 5HT 2A R availability in subjects greater than 60 years old. Methods: Six healthy subjects (age range = 65–78 years) completed two [ 18 F]-setoperone PET scans on two separate occasions 5–16 weeks apart. The average difference in the binding potential (BP ND ) as measured on the two occasions in the frontal and temporal cortical regions ranged between 2 and 12%, with the lowest intraclass correlation coefficient in anterior cingulate regions. We conclude that the test-retest variability of [ 18 F]-setoperone PET in elderly subjects is comparable to that of [ 18 F]-setoperone and other 5HT 2A R radiotracers in younger subject samples

  16. Has the tobacco industry evaded the FDA's ban on 'Light' cigarette descriptors?

    Science.gov (United States)

    Connolly, Gregory N; Alpert, Hillel R

    2014-03-01

    Under the Family Smoking Prevention and Tobacco Control Act (FSPTCA), the Food and Drug Administration (FDA) banned the use of "Lights" descriptors or similar terms on tobacco products that convey messages of reduced risk. Manufacturers eliminated terms explicitly stated and substituted colour name descriptors corresponding to the banned terms. This paper examines whether the tobacco industry complied with or circumvented the law and potential FDA regulatory actions. Philip Morris retailer manuals, manufacturers' annual reports filed with the Massachusetts Department of Public Health, a national public opinion survey, and market-wide cigarette sales data were examined. Manufacturers substituted "Gold" for "Light" and "Silver" for "Ultra-light" in the names of Marlboro sub-brands, and "Blue", "Gold", and "Silver" for banned descriptors in sub-brand names. Percent filter ventilation levels, used to generate the smoke yield ranges associated with "Lights" categories, appear to have been reassigned to the new colour brand name descriptors. Following the ban, 92% of smokers reported they could easily identify their usual brands, and 68% correctly named the package colour associated with their usual brand, while sales for "Lights" cigarettes remained unchanged. Tobacco manufacturers appear to have evaded a critical element of the FSPTCA, the ban on misleading descriptors that convey reduced health risk messages. The FPSTCA provides regulatory mechanisms, including banning these products as adulterated (Section 902). Manufacturers could then apply for pre-market approval as new products and produce evidence for FDA evaluation and determination whether or not sales of these products are in the public health interest.

    Outdoor smoking bans have been implemented to reduce secondhand smoke exposure and cigarette littering. We aimed to explore outdoor smoking behaviours, cigarette littering, and support towards a recently enacted outdoor smoking ban in Baja California, Mexico. From October 2013 to April 2014 a representative sample of 800 adults from urban areas of Baja California was surveyed to obtain information on demographics, smoking status, opinion towards outdoor smoking bans in general and in specific locations, and perceptions and habits regarding cigarette littering. Descriptive statistics and Poisson regression analyses were conducted to estimate prevalence ratios and corresponding 95% CI taking into account the complex survey design. Outdoor smoking was frequently observed, as 86.8% of the population reported having seen people smoking in parks and beaches and 94.4% in open venues such as concerts or stadiums. A smoking ban in all outdoor areas was supported by 71.8% of Baja California residents. Site-specific support ranged from 80% (stadiums) to 89% (public parks). Support for the ban was higher among never and ex-smokers than in current smokers. Cigarette littering was negatively perceived by 98% of the participants, yet 45% of all cigarettes smoked were thrown on the ground. Based on cigarette consumption and butt littering reported in the survey, we estimated that 27 million cigarette butts become litter every month in urban areas of Baja California. Outdoor smoking is still frequent in outdoor areas where people gather, and an important source of littering. We found substantial public support towards the outdoor smoking ban, which should translate into easier implementation and compliance in Baja California, Mexico. © The Author 2015.

    To determine the effects of a 1988 Maryland law that banned "Saturday night special" handguns on the types of guns used in crime. To determine if controls on the lawful market for handguns affect the illegal market as well. Baltimore, Maryland, and 15 other US cities participating in a crime gun tracing project. Cross sectional comparison of the proportion of crime guns that are banned by the Maryland law, comparing Baltimore, MD with 15 other cities outside of Maryland. Multivariate linear regression analysis to determine if observed differences between Baltimore and 15 other cities are explained by demographic or regional differences among the cities rather than Maryland's law. Among crime guns, a gun banned by Maryland's law is more than twice as likely (relative risk (RR) 2.3, 95% confidence interval (CI) 2.0 to 2.5) to be the subject of a crime gun trace request in 15 other cities combined, than in Baltimore. Among homicide guns, a crime especially relevant for public safety, a comparable difference (RR 2.1, 95% CI 1.1 to 4.2) was observed. The proportion of Baltimore's crime guns that are banned is 12 percentage points lower than would be expected based on its demographic and regional characteristics alone. Among crime guns purchased after 1990, a much smaller proportion in Baltimore are banned models than in 15 other cities. Maryland's law has reduced the use of banned Saturday night specials by criminals in Baltimore. Contrary to the claims of some opponents of gun control laws, regulation of the lawful market for firearms can also affect criminals.

  19. Tribal communities and coal in Northeast India: The politics of imposing and resisting mining bans

    International Nuclear Information System (INIS)

    McDuie-Ra, Duncan; Kikon, Dolly

    2016-01-01

    Bans on coal mining have been implemented in two tribal majority states in India's north-east frontier; Nagaland and Meghalaya. In Nagaland the state government imposed the ban in an attempt to capture control of coal extraction and trade, while in Meghalaya India's National Green Commission imposed the ban over concern for the environment and labour conditions. In both cases local communities have opposed the bans, and in some areas resumed mining under the authority of tribal councils and powerful civil society actors. In this paper we explore the politics of coal extraction that resulted in these bans and the response of communities and authorities. In doing so we made three main arguments that contribute to understanding of coal and communities in frontier regions where state control is partial and the legacy of armed conflict is powerful. First, in both locations the majority of the coal mining activity has been initiated and managed by members of tribal communities rather than profit-driven outsiders. Second, in contrast to other contexts in India (notably Orissa and Jharkhand) where large state or private enterprises seek to modify the law to enable coal extraction, in Nagaland and Meghalaya it has been communities that resent and challenge state and national laws being applied to their lands. Third, the right to extract coal is connected to the right of tribal communities to determine what happens on their lands. - Highlights: • Tribal communities initiate and manage coal mining in Nagaland and Meghalaya. • Laws banning coal extraction have been challenged and resisted by local communities. • The right to extract coal is tied to protecting tribal land rights. • Tribal autonomy in coal policy is progressive, yet enables capture by local elites. • Where there has been regulation of coal mining it has come from unexpected sources.

    Objectives—To determine the effects of a 1988 Maryland law that banned "Saturday night special" handguns on the types of guns used in crime. To determine if controls on the lawful market for handguns affect the illegal market as well. Setting—Baltimore, Maryland, and 15 other US cities participating in a crime gun tracing project. Methods—Cross sectional comparison of the proportion of crime guns that are banned by the Maryland law, comparing Baltimore, MD with 15 other cities outside of Maryland. Multivariate linear regression analysis to determine if observed differences between Baltimore and 15 other cities are explained by demographic or regional differences among the cities rather than Maryland's law. Results—Among crime guns, a gun banned by Maryland's law is more than twice as likely (relative risk (RR) 2.3, 95% confidence interval (CI) 2.0 to 2.5) to be the subject of a crime gun trace request in 15 other cities combined, than in Baltimore. Among homicide guns, a crime especially relevant for public safety, a comparable difference (RR 2.1, 95% CI 1.1 to 4.2) was observed. The proportion of Baltimore's crime guns that are banned is 12 percentage points lower than would be expected based on its demographic and regional characteristics alone. Among crime guns purchased after 1990, a much smaller proportion in Baltimore are banned models than in 15 other cities. Conclusions—Maryland's law has reduced the use of banned Saturday night specials by criminals in Baltimore. Contrary to the claims of some opponents of gun control laws, regulation of the lawful market for firearms can also affect criminals. PMID:10628912

    In March 2004, Ireland became the first country to introduce a nationwide workplace smoking ban. The smoking ban increased the non-monetary cost of smoking by prohibiting smoking in the majority of indoor workplaces. The aim of this paper is to examine whether the extra non-monetary cost of smoking was concentrated on the employed. Using two waves of the nationally representative Slán survey, a difference-in-differences approach is used to measure changes in smoking behaviour among the employ...

    We analyse the effects of the advertising ban on French public television, which came into effect on the 5th of January 2009. The ban forbids commercial advertising on public TV in the time slot 20.00-6.00. By using a difference-in-difference approach we show that advertising which was previously broadcasted on public TV in the time slot 20.00-6.00 did not switch to private channels in the same time slot (nor did the price per second in that time slot on private channels rise). Rather adverti...

    The Centre for Accelerator Science facility at ANSTO has been expanded with the new NEC 6 MV ;SIRIUS; accelerator system in 2015. In this paper we present a detailed description of the new nuclear microprobe-Confocal Heavy Ion Micro-Probe (CHIMP) together with results of the microprobe resolution testing and the elemental analysis performed on typical samples of mineral ore deposits and hyper-accumulating plants regularly measured at ANSTO. The CHIMP focusing and scanning systems are based on the OM-150 Oxford quadrupole triplet and the OM-26 separated scan-coil doublet configurations. A maximum ion rigidity of 38.9 amu-MeV was determined for the following nuclear microprobe configuration: the distance from object aperture to collimating slits of 5890 mm, the working distance of 165 mm and the lens bore diameter of 11 mm. The overall distance from the object to the image plane is 7138 mm. The CHIMP beamline has been tested with the 3 MeV H+ and 6 MeV He2+ ion beams. The settings of the object and collimating apertures have been optimized using the WinTRAX simulation code for calculation of the optimum acceptance settings in order to obtain the highest possible ion current for beam spot sizes of 1 μm and 5 μm. For optimized aperture settings of the CHIMP the beam brightness was measured to be ∼0.9 pA μm-2 mrad-2 for 3 MeV H+ ions, while the brightness of ∼0.4 pA μm-2 mrad-2 was measured for 6 MeV He2+ ions. The smallest beam sizes were achieved using a microbeam with reduced particle rate of 1000 Hz passing through the object slit apertures several micrometers wide. Under these conditions a spatial resolution of ∼0.6 μm × 1.5 μm for 3 MeV H+ and ∼1.8 μm × 1.8 μm for 6 MeV He2+ microbeams in horizontal (and vertical) dimension has been achieved. The beam sizes were verified using STIM imaging on 2000 and 1000 mesh Cu electron microscope grids.

  7. The need for combining IEA and IE tools. The potential effects of a global ban on PVC on climate change

    2008-01-01

    Over the last decades the concepts of Integrated Environmental Assessment (IEA) and Industrial Ecology (IE), both claiming to provide analyses and solutions for sustainability issues, have been developed separately as they emerged in response to questions from different policy-fields. In both fields, specific tools are used to support national and international environmental policy. The focus of IEA and IE tools, however, is different. IEA tools focus on one or a limited number of specific environmental issues. They often model the chain environmental processes with high spatial (and temporal) resolution, but have a low resolution for the material structure of the economy and only partly take into account indirect effects that occur via physical and socio-economic linkages. IE tools take into account all environmental issues related to a specific substance or product. They have a high resolution for the material structure of the economy and take into account indirect effects that occur via physical linkages, however, their environmental modelling is very limited. Both IE and IEA tools have proven to be very useful and neither is superior to the other. However, a combination of both can provide additional information that can be used for more effective policy making. We use the case of a hypothetical world-wide ban on PVC to show that a measure that is not directly related to climate change could still have significant climate effects. This indirect effect is a result of the linkages of material flows in society. We show that IEA tools are not well suited to include these types of effects and that IE tools can fill this gap partially. What is really needed is a broader systems perspective that takes into account the full range of possible side-effects of environmental policy measures. (author)

    Real-Time PCR-High Resolution Melting (qPCR-HRM) analysis has been recently described for rapid drug susceptibility testing (DST) of Mycobacterium leprae. The purpose of the current study was to further evaluate the validity, reliability, and accuracy of this assay for M. leprae DST in clinical specimens. The specificity and sensitivity for determining the presence and susceptibility of M. leprae to dapsone based on the folP1 drug resistance determining region (DRDR), rifampin (rpoB DRDR) and ofloxacin (gyrA DRDR) was evaluated using 211 clinical specimens from leprosy patients, including 156 multibacillary (MB) and 55 paucibacillary (PB) cases. When comparing the results of qPCR-HRM DST and PCR/direct DNA sequencing, 100% concordance was obtained. The effects of in-house phenol/chloroform extraction versus column-based DNA purification protocols, and that of storage and fixation protocols of specimens for qPCR-HRM DST, were also evaluated. qPCR-HRM results for all DRDR gene assays (folP1, rpoB, and gyrA) were obtained from both MB (154/156; 98.7%) and PB (35/55; 63.3%) patients. All PCR negative specimens were from patients with low numbers of bacilli enumerated by an M. leprae-specific qPCR. We observed that frozen and formalin-fixed paraffin embedded (FFPE) tissues or archival Fite's stained slides were suitable for HRM analysis. Among 20 mycobacterial and other skin bacterial species tested, only M. lepromatosis, highly related to M. leprae, generated amplicons in the qPCR-HRM DST assay for folP1 and rpoB DRDR targets. Both DNA purification protocols tested were efficient in recovering DNA suitable for HRM analysis. However, 3% of clinical specimens purified using the phenol/chloroform DNA purification protocol gave false drug resistant data. DNA obtained from freshly frozen (n = 172), formalin-fixed paraffin embedded (FFPE) tissues (n = 36) or archival Fite's stained slides (n = 3) were suitable for qPCR-HRM DST analysis.

  10. The ban on "off-label" pharmaceutical promotion: constitutionally permissible prophylaxis against false or misleading commercial speech?

    Science.gov (United States)

    Greenwood, Kate

    2011-01-01

    Critics of the Food & Drug Administration's ban on off-label promotion often claim that it violates the First Amendment because it suppresses pharmaceutical manufacturers' truthful speech about their legal--and beneficial--products. Characterizing the ban on off-label promotion in this way has more than rhetorical significance. Bans on truthful, non-misleading speech elicit special skepticism because of the belief that they "usually rest solely on the offensive assumption that the public will respond 'irrationally' to the truth." The legislative history of the provisions of the Food Drug and Cosmetic Act that underlie the ban on off-label promotion, however, reveals that Congress was concerned that physicians were responding rationally to false and misleading promotional claims. In this Article, I explore the doctrinal questions raised by conceiving of the ban on off-label promotion not as a ban on "truthful speech to physicians" but instead as a prophylaxis against false and misleading pharmaceutical promotion. I review the evidence that false and misleading claims were commonplace before the ban's adoption and persist today, along with the enforcement challenges the FDA confronted at that time and would confront were the ban lifted, and conclude the government likely could develop the factual record necessary to establish that Congress' rejection of an after-the-fact case-by-case approach to combating false and misleading prescription drug promotion is constitutional.

  11. Substance abuse treatment counselors and tobacco use: a comparison of comprehensive and indoor-only workplace smoking bans.

    Knudsen, Hannah K; Boyd, Sara E; Studts, Jamie L

    2010-11-01

    While indoor smoking bans reduce employee tobacco use, less is known about whether comprehensive bans, which prohibit smoking in both indoor and outdoor areas, are associated with lower rates of tobacco use than indoor-only bans. This study integrated data collected via mailed surveys from 1,910 substance abuse treatment counselors and telephone interviews with 417 administrators of substance abuse treatment organizations. Multinomial logistic regression was used to estimate the associations between counselors' self-reported tobacco use and administrators' reports about organizational smoking bans while controlling for counselors' professional and demographic characteristics. In this sample, 20.3% of counselors were current tobacco users, 47.7% identified as former users, and 32.0% reported never using tobacco products. Only 19.5% of counselors worked in a treatment organization that had a comprehensive smoking ban. The likelihood of being a current tobacco user, compared with being a former user or nonuser, was significantly lower for counselors in organizations with comprehensive bans even after controlling for professional and demographic characteristics. Although relatively few substance abuse counselors worked in treatment organizations with comprehensive bans, such bans may represent a promising direction for tobacco control. Given recent research documenting how tobacco use is negatively associated with the delivery of smoking cessation services by health care workers, additional research on the impact of comprehensive environmental tobacco policies is needed.

    A workplace-smoking ban in the Netherlands was introduced on January 1, 2004. Before the ban male and low educated employees were at higher risk for exposure to environmental tobacco smoke (ETS). Effective implementation of the ban should result not only in an overall decline of exposure, but also in the disappearance of systematic differences in exposure between subgroups of employees. Data from a Dutch continuous Internet survey were used. From July 2003 through June 2005, 200 respondents were randomly selected each week. The sample consisted of 11,291 non-smoking, working respondents, aged 16-65 years. ETS exposure decreased among all employees and among subgroups at higher risk before the ban. However, also after the ban, males and low educated employees were still most likely to be exposed to ETS. The workplace-smoking ban was effective in reducing ETS exposure among employees. However, after the ban still 52.2% of non-smoking workers reported to be exposed. We did not find the expected stronger effect among employees who were at higher risk. Both before and after implementation of the ban, males and lower educated employees were about two times more likely to be exposed to ETS.

    An accurate in vivo measure of myelin content is essential to deepen our insight into the mechanisms underlying demyelinating and dysmyelinating neurological disorders, and to evaluate the effects of emerging remyelinating treatments. Recently [(11)C]PIB, a positron emission tomography (PET) tracer originally conceived as a beta-amyloid marker, has been shown to be sensitive to myelin changes in preclinical models and humans. In this work, we propose a reference-region methodology for the voxelwise quantification of brain white-matter (WM) binding for [(11)C]PIB. This methodology consists of a supervised procedure for the automatic extraction of a reference region and the application of the Logan graphical method to generate distribution volume ratio (DVR) maps. This approach was assessed on a test-retest group of 10 healthy volunteers using a high-resolution PET tomograph. The [(11)C]PIB PET tracer binding was shown to be up to 23% higher in WM compared with gray matter, depending on the image reconstruction. The DVR estimates were characterized by high reliability (outliers 0.95). [(11)C]PIB parametric maps were also found to be significantly correlated (R(2)>0.50) to mRNA expressions of the most represented proteins in the myelin sheath. On the contrary, no correlation was found between [(11)C]PIB imaging and nonmyelin-associated proteins.

    Since its release as anti-anemic drug, recombinant erythropoietin (rEPO) gradually entered the illicit way to sports competitions as endurance-enhancing drug. Novel modifications biopharmaceutically introduced into the rEPO molecule in the form of carbohydrate or polyethylene glycol moieties made robust and sensitive test methods vital to doping controls in order to provide the necessary tools enabling the conviction of dishonest athletes. Modern protein analysis by means of gel electrophoretic separation and western blotting represents the status quo in rEPO anti-doping analysis. However, new therapeutically promising erythropoietin receptor activating compounds have been developed that exhibit cytokine hormone-mimicking properties but lack any protein structure. Progression to evade parenteral application and substitute for rEPO by low molecular mass and orally available compounds is still one of the major objectives in pharmaceutical research. In this approach, four promising in-house synthesized nonpeptidic erythropoietin mimetic agents, namely compound 129, compound 163, A1B10C1, and A5B10C4 were thoroughly evaluated by employing high-resolution/high-accuracy liquid chromatography tandem mass spectrometry experiments. Characteristic product ions were determined supporting the identification of these drugs and putative metabolites as well as related compounds in future doping controls. Test methods employing direct urine injection and receptor affinity purification strategies were assessed, which demonstrated that EPO receptor purification is of limited utility for nonpeptidic EPOR agonists while direct urine injection allowed for comprehensive method characterization. Thereby, achieved limits of detection were 1 ng/mL for compounds 129/163 and 5 ng/mL for A1B10C1/A5B10C4.

    A novel strategy which combines iteratively cubic spline fitting baseline correction method with discriminant partial least squares qualitative analysis is employed to analyze the surface enhanced Raman scattering (SERS) spectroscopy of banned food additives, such as Sudan I dye and Rhodamine B in food, Malachite green residues in aquaculture fish. Multivariate qualitative analysis methods, using the combination of spectra preprocessing iteratively cubic spline fitting (ICSF) baseline correction with principal component analysis (PCA) and discriminant partial least squares (DPLS) classification respectively, are applied to investigate the effectiveness of SERS spectroscopy for predicting the class assignments of unknown banned food additives. PCA cannot be used to predict the class assignments of unknown samples. However, the DPLS classification can discriminate the class assignment of unknown banned additives using the information of differences in relative intensities. The results demonstrate that SERS spectroscopy combined with ICSF baseline correction method and exploratory analysis methodology DPLS classification can be potentially used for distinguishing the banned food additives in field of food safety.

    Forest protection policies potentially reduce deforestation and re-direct agricultural expansion to already-cleared areas. Using satellite imagery, we assessed whether deforestation for conversion to pasture and cropland decreased in the lowlands of northern Costa Rica following the 1996 ban on forest clearing, despite a tripling of area under pineapple cultivation in the last decade. We observed that following the ban, mature forest loss decreased from 2.2% to 1.2% per year, and the proportion of pineapple and other export-oriented cropland derived from mature forest declined from 16.4% to 1.9%. The post-ban expansion of pineapples and other crops largely replaced pasture, exotic and native tree plantations, and secondary forests. Overall, there was a small net gain in forest cover due to a shifting mosaic of regrowth and clearing in pastures, but cropland expansion decreased reforestation rates. We conclude that forest protection efforts in northern Costa Rica have likely slowed mature forest loss and succeeded in re-directing expansion of cropland to areas outside mature forest. Our results suggest that deforestation bans may protect mature forests better than older forest regrowth and may restrict clearing for large-scale crops more effectively than clearing for pasture.

  18. The ban on reprocessing as seen from the perspective of European law

    International Nuclear Information System (INIS)

    Hanenburg, E.; Warg, G.

    1999-01-01

    The plan of the German federal government to opt out of the peaceful uses of nuclear power for electricity generation initially was to incorporate also a ban on reprocessing spent fuel elements. On February 22, 1999, Federal Minister for the Environment Trittin finally announced that his revised draft for the time being would contain no ban on reprocessing. That ban, as originally planned, raises a number of issues of European law which are analyzed in the article by Hanenburg and Warg, especially the question whether the ban on reprocessing constitutes a violation of the principles and objectives of the Common Market. The legal principles underlying the Common Market, especially the Euratom Treaty among the member countries, constitute the basis of the analysis in which, inter alia, aspects such as cross-border reprocessing and secondary European law or the legal consequences of the Euratom Treaty for the opting-out policy of the German federal government are dealt with. The analysis arrives at the finding that a final opt-out as planned by the German federal government in the amendments to the Atomic Energy Act, and the complete substitution of nuclear electricity by other sources of energy, violate the purpose of the Euratom Treaty at least to keep open the structural possibility of generating electricity by nuclear power.

    Full Text Available While extant research on the impacts of smoke-free legislation on hospitality employees and industries has centered on developed countries, the research on the effects of smoking bans in transition countries has received very little attention. Hoping to assist in filling this void, this research empirically explores the relationships among restaurant employees’ attitudes, demographics, work-related variables (WRV, and job satisfaction after the introduction of a smoke-free legislation in one transition economy, i.e. Croatia. Results revealed that gender, education, age, restaurant seating allocation, hospitality work experience, smoking status, average weekly workload, and the restaurant area served were for the most part not significant in explaining different perceptions toward a smoking ban. However, the respondents’ preferred restaurant smoking policy somewhat influenced how respondents view the smoking ban. In terms of the respondents’ preferred restaurant smoking policy, results revealed no significant differences in regards to demographics and WRV. With regard to job satisfaction, staff with more positive post-implementation attitudes towards the ban exhibit somewhat higher levels of satisfaction with the current job. Overall, respondents appear willing to make concessions for both pro- and anti-smoking patrons, staff, and owners/managers. Therefore, lawmakers should consider population characteristics, seating allocation, and the combination thereof when devising restaurant smoking policies.

    2017-10-01

    Full Text Available This article describes the history of the asbestos use regulation process in Taiwan and the associated factors leading to its total ban in 2018. Despite the long history of asbestos mining and manufacturing since the Japanese colonial period, attempts to understand the impact of asbestos on the health of the population and to control its use did not emerge until the early 1980s. We attempted to investigate the driving forces and obstructions involved in asbestos regulations by reviewing available public sources and scientific journal articles and conducting interviews with key propagators of the asbestos regulation and ban. Correlation between asbestos exposure and asbestos-related diseases has already been established; however, authorities have been unable to effectively regulate the extensive application of asbestos in various light industries that support economic growth since the 1960s. More stringent regulations on asbestos use in industries and an eventual ban were caused indirectly by appeals made by visionary scholars and healthcare professionals but also due to the subsidence of asbestos-related industries. With the elucidation of factors that affect asbestos regulation and ban, a thorough long-term healthcare plan for the neglected victims of asbestos-related diseases and upstream measures for policy change must be developed.

    Healthy public policy is an important tool for creating environments that support human health and wellbeing. At the local level, municipal policies, such as zoning bylaws, provide an opportunity for governments to regulate building location and the type of services offered. Across North America, there has been a recent proliferation of municipal bylaws banning fast food drive-through services. Research on the utilization of this policy strategy, including bylaw adopters and adopter characteristics, is limited within the Canadian context. The aim of this study was to identify and characterize Canadian municipalities based on level of policy innovation and nature of their adopted bylaw banning fast food drive-through services. A multiple case history methodology was utilized to identify and analyse eligible municipal bylaws, and included development of a chronological timeline and map of adopter municipalities within Canada. Grey literature and policy databases were searched for potential adopters of municipal fast food drive-through service bylaws. Adopters were confirmed through evidence of current municipal bylaws. Geographic diffusion and diffusion of innovations theories provided a contextual framework for analysis of bylaw documents. Analysis included assignment of adopter-types, extent and purpose of bans, and policy learning activities of each adopter municipality. From 2002 to 2016, 27 municipalities were identified as adopters: six innovators and twenty-one early adopters. Mapping revealed parallel geographic diffusion patterns in western and eastern Canada. Twenty-two municipalities adopted a partial ban and five adopted a full ban. Rationales for the drive-through bans included health promotion, environmental concerns from idling, community character and aesthetics, traffic concerns, and walkability. Policy learning, including research and consultation with other municipalities, was performed by nine early adopters. This study detailed the adoption of

  5. Resolution Enhancement of Multilook Imagery

    Energy Technology Data Exchange (ETDEWEB)

    Galbraith, Amy E. [Univ. of Arizona, Tucson, AZ (United States)

    2004-07-01

    This dissertation studies the feasibility of enhancing the spatial resolution of multi-look remotely-sensed imagery using an iterative resolution enhancement algorithm known as Projection Onto Convex Sets (POCS). A multi-angle satellite image modeling tool is implemented, and simulated multi-look imagery is formed to test the resolution enhancement algorithm. Experiments are done to determine the optimal con guration and number of multi-angle low-resolution images needed for a quantitative improvement in the spatial resolution of the high-resolution estimate. The important topic of aliasing is examined in the context of the POCS resolution enhancement algorithm performance. In addition, the extension of the method to multispectral sensor images is discussed and an example is shown using multispectral confocal fluorescence imaging microscope data. Finally, the remote sensing issues of atmospheric path radiance and directional reflectance variations are explored to determine their effect on the resolution enhancement performance.

    Full Text Available Objectives: More and more countries introduce a total ban on smoking tobacco in public places. The aim of this work was to evaluate the effectiveness of “The Act of 8 April 2010 on amendment of the act on protection of health against the consequences of consumption of tobacco and tobacco products and act on National Sanitary Inspectorate” and assess the frequency of complying with the smoking bans by the students of the Medical University of Lodz, Poland. Material and Methods: Between 2007–2011, at the Social Medicine Institute of the Medical University of Lodz, a study using random survey was carried out involving students who were starting their studies at the Health Department of the Medical University of Lodz. The analysis of the collected material showed that 1038 people reported being smokers at the time of the study. Among that group, 530 students were included in the study prior to, and 508 after the introduction of the amendment. In order to verify their compliance with the smoking ban, the respondents were asked whether they smoked only in designated areas or wherever they wanted to. Results: The ratio of people claiming they smoked anywhere they wanted to, disregarding the smoking ban, was 60% (N = 318 and after the amendment had been introduced, this ratio was 62.2% (N = 316, it increased by 2.2 percentage points. The observed difference was statistically irrelevant (Chi2 = 0.530, p > 0.05. Conclusions: The Act ”On amendment of the act on protection of health against the consequences of consumption of tobacco and tobacco products and Act on National Sanitary Inspectorate” in Poland did not result in the expected changes in the frequency of complying with the smoking ban by the 1st year students.

    To investigate the extent of cigarette smoking, knowledge of health hazards and attitudes towards the ban of smoking in Shantou, China, as causes for failure to control smoking. Environmental monitoring and population survey. Particulate matter (PM2.5) measurements were conducted in randomly selected public places (restaurants, non-alcoholic drink shops and internet bars) and exposure-related health hazards were evaluated. University students and adult citizens were randomly selected to determine their extent of cigarette smoking, knowledge of health hazards and attitude towards the ban of smoking in public places. The collected data were used to evaluate possible causes and solutions to the smoking problem. From PM2.5 measurements, the average indoor to outdoor concentrations in non-smoking restaurants were 33.4 vs. 30.6 μg/m(3), P > 0.05; average indoor of smoking restaurants was 350.0% higher, P  0.001. From our survey of 1100 university students: 1) 17.5% and 7.5% were active male and female smokers, respectively; and 2) 57.5% of students would accept a smoke-ban policy. From 502 adult citizens: 1) 27.5% were active male smokers; 2) Approximately 40 and 60% had inadequate knowledge of health hazards from smoking and second-hand smoke exposure; and 3) >90% of them would accept a smoke-ban policy. Our data indicate that failure to ban smoking was not caused by resistance from smokers but inadequate (national and local) government effort to educate the public and to enforce existing policy. The data suggest that development of a citizen-based approach, in collaboration with willing officials, may be highly successful in the control of cigarette smoking in China.

    The study aimed to assess the effect of the introduction on 1 January 2003 of a legal tobacco sales ban in The Netherlands on tobacco purchases by smoking and non-smoking adolescents aged <16 years. Two cross-sectional surveys were conducted among adolescents aged 13 through 15 years, one at end 1999 (n = 4751) and the other at end 2003 (n = 13 298). The percentage of adolescents buying tobacco decreased significantly from 26.3% in 1999 to 10.8% in 2003 (P < 0.001). Further analysis showed that, after the ban, the proportion of smokers among buyers almost tripled [Odds Ratio (OR) = 2.9], while the likelihood of non-smokers buying tobacco decreased strongly (OR = 0.17). A difference in the pattern of purchasing tobacco also emerged after the ban. In 2003, the proportion of smokers buying at least weekly in commercial outlets was larger than in 1999. For non-smokers there was no difference between 1999 and 2003 in the proportion buying weekly. The variety of commercial outlets in which purchases were made increased among both smoking and non-smoking purchasers of tobacco. Implementation of the 2003 tobacco sales ban has had the (intended) effect of lowering tobacco purchases among adolescents. This was mainly due to the decrease in the likelihood of buying tobacco among those who regard themselves as a non-smoker. The decrease in buying tobacco is associated with a decrease in prevalence of smoking. The sales ban has probably contributed to a stronger decrease in prevalence of smoking.

      The US Food and Drug Administration must consider whether to ban the use of menthol in cigarettes. This study examines how current smokers might respond to such a ban on menthol cigarettes.   Convenience sample of adolescent and adult smokers recruited from an online survey panel.   United States, 2010.   A total of 471 adolescent and adult current cigarette smokers.   Respondents were asked a series of questions about how they might react if menthol cigarettes were banned. In addition, participants completed a simulation purchase task to estimate the demand for menthol and non-menthol cigarettes across a range of prices.   Overall, 36.1% of respondents said they always (18.9%) or usually (17.2%) smoked menthol cigarettes. When asked how they might respond to a ban on menthol cigarettes, 35% of current menthol smokers said they would stop smoking, and 25% said they would 'find a way to buy a menthol brand'. Those who reported they might quit tended to have greater current intentions to quit [odds ratio (OR) = 4.47], while those who reported that they might seek illicit menthol cigarettes were far less likely to report current intentions to quit (OR = 0.06). Estimates for demand elasticity for preferred cigarette type were similar for menthol (α = 0.0051) and non-menthol (α = 0.0049) smokers. Demand elasticity and peak consumption were related to usual cigarette type and cigarettes smoked per day, but did not appear to differ by race, gender or age.   Preliminary evidence suggests that a significant minority of smokers of menthol cigarettes in the United States would try to stop smoking altogether if such cigarettes were banned. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    2009-01-01

    Background: Mixed connective tissue disease (MCTD) is associated with several chest manifestations. Only a few studies have focused on chest manifestations in juvenile-onset MCTD (jMCTD), and the true prevalence of pulmonary abnormalities on high-resolution computed tomography (HRCT) in these patients is unknown. Purpose: To investigate the occurrence of pulmonary abnormalities in jMCTD with particular reference to interstitial lung disease (ILD), and to evaluate a possible association between pulmonary findings and disease-related variables. Material and Methods: Twenty-four childhood-onset MCTD patients with median disease duration of 10.5 years (range 1-21 years) were investigated in a cross-sectional study by means of HRCT, pulmonary function tests (PFT), and clinical assessment. Results: Discrete ILD was identified in six patients (25%). Median extent of ILD was 2.0%, and all except one of the patients had very mild disease in which 5% or less of the parenchyma was affected. The CT features of fibrosis were mainly microcystic and fine intralobular. The most frequently abnormal PFT was carbon monoxide uptake from the lung, which was abnormal in 33% of the patients. PFT and disease duration were not significantly associated with HRCT findings of ILD. Conclusion: The prevalence of ILD in childhood-onset MCTD patients was lower than previously believed. In most of the patients with ILD, the findings were subtle and without clinical correlation. The results suggest a low extent of ILD in childhood-onset MCTD, even after long-term disease duration

  13. Monte Carlo Bayesian Inference on a Statistical Model of Sub-gridcolumn Moisture Variability Using High-resolution Cloud Observations . Part II; Sensitivity Tests and Results

    da Silva, Arlindo M.; Norris, Peter M.

    2013-01-01

    Part I presented a Monte Carlo Bayesian method for constraining a complex statistical model of GCM sub-gridcolumn moisture variability using high-resolution MODIS cloud data, thereby permitting large-scale model parameter estimation and cloud data assimilation. This part performs some basic testing of this new approach, verifying that it does indeed significantly reduce mean and standard deviation biases with respect to the assimilated MODIS cloud optical depth, brightness temperature and cloud top pressure, and that it also improves the simulated rotational-Ramman scattering cloud optical centroid pressure (OCP) against independent (non-assimilated) retrievals from the OMI instrument. Of particular interest, the Monte Carlo method does show skill in the especially difficult case where the background state is clear but cloudy observations exist. In traditional linearized data assimilation methods, a subsaturated background cannot produce clouds via any infinitesimal equilibrium perturbation, but the Monte Carlo approach allows finite jumps into regions of non-zero cloud probability. In the example provided, the method is able to restore marine stratocumulus near the Californian coast where the background state has a clear swath. This paper also examines a number of algorithmic and physical sensitivities of the new method and provides guidance for its cost-effective implementation. One obvious difficulty for the method, and other cloud data assimilation methods as well, is the lack of information content in the cloud observables on cloud vertical structure, beyond cloud top pressure and optical thickness, thus necessitating strong dependence on the background vertical moisture structure. It is found that a simple flow-dependent correlation modification due to Riishojgaard (1998) provides some help in this respect, by better honoring inversion structures in the background state.

    Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and the smoking behaviour of those populations they affect. Since the first version of this review in 2010, more countries have introduced national smoking legislation banning indoor smoking. To assess the effects of legislative smoking bans on (1) morbidity and mortality from exposure to secondhand smoke, and (2) smoking prevalence and tobacco consumption. We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL and reference lists of included studies. We also checked websites of various organisations. Date of most recent search; February 2015. We considered studies that reported legislative smoking bans affecting populations. The minimum standard was having an indoor smoking ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. Our search included a broad range of research designs including: randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before-and-after studies, interrupted time series as defined by the Cochrane Effective Practice and Organisation of Care Group, and uncontrolled pre- and post-ban data. One author extracted characteristics and content of the interventions, participants, outcomes and methods of the included studies and a second author checked the details. We extracted health and smoking behaviour outcomes. We did not attempt a meta-analysis due to the heterogeneity in design and content of the studies included. We evaluated the studies using qualitative narrative synthesis. There are 77 studies included in this updated review. We retained 12 studies from the original review and identified 65 new studies. Evidence from 21 countries is

    Full Text Available Abstract Background Implementation of smoke free policies has potentially substantial effects on health by reducing secondhand smoke exposure. However little is known about whether the introduction of anti-smoking legislation translates into decreased secondhand smoke exposure. We examined whether smoking bans impact rates of secondhand smoke exposure in public places and rates of complete workplace smoking restriction. Methods Canadian Community Health Survey was used to obtain secondhand smoking exposure rates in 15 Ontario municipalities. Data analysis included descriptive summaries and 95% confidence intervals were calculated and compared across groups Results Across all studied municipalities, secondhand smoke exposure in public places decreased by 4.7% and workplace exposure decreased by 2.3% between the 2003 and 2005 survey years. The only jurisdiction to implement a full ban from no previous ban was also the only setting that experienced significant decreases in both individual exposure to secondhand smoke in a public place (-17.3%, 95% CI -22.8, -11.8 and workplace exposure (-18.1%, 95% CI -24.9, -11.3. Exposures in vehicles and homes declined in almost all settings over time. Conclusions Implementation of a full smoking ban was associated with the largest decreases in secondhand smoke exposure while partial bans and changes in existing bans had inconsistent effects. In addition to decreasing exposure in public places as would be expected from legislation, bans may have additional benefits by decreasing rates of current smokers and decreasing exposures to secondhand smoke in private settings.

    Implementation of smoke free policies has potentially substantial effects on health by reducing secondhand smoke exposure. However little is known about whether the introduction of anti-smoking legislation translates into decreased secondhand smoke exposure. We examined whether smoking bans impact rates of secondhand smoke exposure in public places and rates of complete workplace smoking restriction. Canadian Community Health Survey was used to obtain secondhand smoking exposure rates in 15 Ontario municipalities. Data analysis included descriptive summaries and 95% confidence intervals were calculated and compared across groups Across all studied municipalities, secondhand smoke exposure in public places decreased by 4.7% and workplace exposure decreased by 2.3% between the 2003 and 2005 survey years. The only jurisdiction to implement a full ban from no previous ban was also the only setting that experienced significant decreases in both individual exposure to secondhand smoke in a public place (-17.3%, 95% CI -22.8, -11.8) and workplace exposure (-18.1%, 95% CI -24.9, -11.3). Exposures in vehicles and homes declined in almost all settings over time. Implementation of a full smoking ban was associated with the largest decreases in secondhand smoke exposure while partial bans and changes in existing bans had inconsistent effects. In addition to decreasing exposure in public places as would be expected from legislation, bans may have additional benefits by decreasing rates of current smokers and decreasing exposures to secondhand smoke in private settings.

    The radionuclide network of the IMS consists of 80 radionuclide stations monitoring radioactive airborne particulate. The air sampling systems at these stations require high technical standards regarding robustness, calibration and reliability. These systems are and will be deployed at locations where very different and often very harsh environmental conditions can dominate. An overview of sampling systems is given taking in consideration environmental and operational constraints. Because of lack of experience running radionuclide stations at the required standards, several issues are still open and need consideration for future installations and operation. (orig.) [German] Das Internationale Ueberwachungssystem des Vertrages ueber das umfassende Verbot von Nuklearversuchen besteht unter anderem aus 80 Radionuklidstationen, die radioaktive Partikeln in der Luft messen. Die Luftprobenahmesysteme an diesen Stationen muessen einem hohen technischen Standard in bezug auf Widerstandsfaehigkeit, Zuverlaessigkeit und Kalibrierung entsprechen, da sie auch an Standorten mit wechselhaften und oft sehr rauhen Umweltbedingungen installiert werden. Ein Ueberblick verschiedener Luftprobenahmesysteme, der Betriebseinschraenkungen und der lokal vorhandenen Infrastruktur beruecksichtigt, wird gegeben. Aufgrund mangelnder Erfahrung beim Betrieb von Radionuklidstationen unter den vorgeschriebenenStandards, sind viele Aspekte noch nicht geklaert und beduerfen weiterer Ueberlegungen bezueglich des Betriebes und zukuenftiger Installationen.

    In order to keep abreast on issues related to CTBT in Malaysia, Malaysian Nuclear Agency (Nuklear Malaysia), as the CTBT National Authority in Malaysia, has collaborated with local partners to implement various stakeholder engagement programme. This paper aims at highlighting Malaysia’s approach in promoting CTBT through stakeholder engagement programme targeted at multilevel stakeholders, both national and international. Such programmes includes participation in the international forums, inter-agency meetings, awareness seminars, training courses, technical visits to IMS station, promoting civil and scientific application of International Monitoring System (IMS) data and International Data Centre (IDC) products using Virtual Data Exploitation Center (vDEC), inviting youth groups to participate in the CTBTO Youth Group, and publications of CTBT-related topics. This approach has successfully fortify Malaysia’s commitments at the international level, enhanced national awareness of global multilateral framework, increased stakeholders awareness and their roles related to CTBT, as well as building domestic capacity on CTBT matters. In conclusion, stakeholder engagement is crucial in promoting and enhancing stakeholders understanding on CTBT. Continuous engagement with relevant stakeholders will enable effective dissemination and smooth implementation of CTBT related matters that will eventually support global universalization of CTBT.

    The Treaty provides for a comprehensive global verification regime, which consists of an International Monitoring System (IMS), consultation and clarification procedures, provisions for requesting on-site inspections, and confidence-building measures. The present verification regime is the result of many years of negotiations led by an international Group of Scientific Experts (GSE) at the Conference on Disarmament in Geneva to ensure that non-compliance with the provisions of the Treaty can be detected in a timely manner. The 337 IMS monitoring facilities (170 seismic, 11 hydroacoustic, 60 infrasound, 80 radionuclide stations and 16 radionuclide laboratories) are located all over the world including in some of the most remote regions such as the Arctic and Antarctica. The seismic, hydroacoustic, infrasound and radionuclide monitoring technologies are designed to register sound and energy vibrations underground, in the sea and in the air, and to detect radionuclides released into the atmosphere. IMS data is collected and transmitted via the state-of-the-art, satellite-based Global Communications Infrastructure (GCI) to the International Data Centre (IDC) at the Commission's headquarters in Vienna. Here the data are processed and, together with IDC products such as Reviewed Event Bulletins and other event screening services, released to Member States for final analysis.

    CVS Health has taken a strategic marketing move by banning tobacco sales. They risk losing customers who buy medications and cigarettes at their drugstores. They estimate they will lose 2 billion dollars by banning cigarette sales. CVS Health believes they will benefit from being regarded as health care partner by insurers and banning cigarette sales is an important step in being recognized as such. The Affordable Care Act expanded access to pharmacy-based medical clinics, increased affordability of medications, and expanded the clinical role of pharmacists. CVS Health is positioning itself to take advantage of these changes.

    This paper investigates the impact of the public smoking ban which came into effect in Italy on January 2005 on individual smoking behaviour. Current empirical evidence supports the existence of a negative effect of the Italian ban on smoking prevalence and consumption in the general population. This is in contrast to what has been found in some other European coun- tries. Our analysis shows that the apparent success of the Italian smoking ban is due to the fact that existing results do not t...

  5. The impacts of the export ban on Alaskan crude oil trade

    The authors investigated the petroleum markets impacts of lifting the ban on Alaska North Slope (ANS) crude oil exports. This paper reports on some aspects of this investigation. The economic analysis relied heavily on the modeling of the ANS crude trade conducted on behalf of GAO by the Energy Information Administration (EIA) using the Transportation and Refining of International Petroleum model (TRIP). In contrast to previous studies, this one suggests that transportation costs may not be the only major factor in the realignment of ANS crude trade in response to lifting the ban. The differences in the yields of ANS crude and various crudes used by refiners in Pacific Rim countries on the one hand, and the product demand slates of the US West Coast and the potential buyers of ANS crude in Pacific Rim may also figure prominently in determining the reallocation of ANS crude if exports are permitted

    The glycopeptide growth promoter avoparcin was banned from animal production in the EU in 1997 due to concern for the spread of vancomycin-resistant enterococci (VRE) from food animals to humans. In recent Norwegian and Danish studies, extensive occurrence of VRE on broiler farms and in broiler...... flocks after the avoparcin ban has been reported. The present study was undertaken to investigate the epidemiology of VRE on broiler farms in the absence of the selective pressure exerted by avoparcin. Environmental samples were obtained from five broiler houses after depopulation, cleaning......, and disinfection of the houses between rotations, and two consecutive broiler flocks from each house were sampled by taking cloacal swabs from the broilers at the time of slaughter. A total of 69 vancomycin-resistant Enterococcus faecium isolates obtained from broiler flocks and broiler houses were subjected...

    Secondhand smoke exposure is estimated to account for 3000 cancer deaths per year. While several countries and states in the U.S. have passed comprehensive smoke-free laws to protect all employees, a significant number of workers are still not protected. The purpose of this study was to determine the effects of passing a comprehensive smoking ban that included bars and restaurants on biomarkers of nicotine and carcinogen exposure. The urines of non-smoking employees (N=24) of bars and restaurants that allowed smoking prior to the smoke-free law were analyzed before and after the law was passed in Minnesota. The results showed significant reductions in both total cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) (free plus glucuronidated) after the ban was instituted. These results provide further support for the importance of protecting employees working in all venues. PMID:20354127

    2016-01-01

    Shot from hunting adds toxic lead to environments worldwide. Existing lead shot regulations have been instituted with little understanding of hunter beliefs and attitudes. This study applied the Theory of Reasoned Action, using a multilevel, multivariate approach, to clarify how positive and negative beliefs relate to attitudes about a ban on lead shot. Structure coefficients and commonality analysis were employed to further examine relationships between beliefs and attitudes. Results suggest that while both positive and negative outcomes influence attitudes, positive outcomes were more influential for supporters and negative beliefs for opposers. Management may need to focus on the results from hunters who indicated that they would be unlikely to support a ban, as these hunters include those who may actively oppose additional efforts to regulate lead.

    2010-01-01

    Smoking is a well-established risk factor for cardiovascular disease (CVD) and acute myocardial infarction (AMI). Exposure to tobacco smoke is associated with an estimated 35,000 cardiovascular deaths per year in nonsmokers. In addition, the risk of CVD decreases with the cessation of exposure to smoking. Association of smoking with CVD has been well known for years; however, association of secondhand smoke with CVD has been a topic of great interest, especially for the past 2 decades. Multiple studies and articles have evaluated the impact of smoking ban on the incidence of AMI-related hospitalizations. In this article, we discuss the effect of smoking ban on the economy and on human health in general, as well as its potential effects on the prevalence of smoking.

    2006-10-01

    To study the effect of a teachers' ban on supervising sports-related extracurricular physical activities (ECAs), levels of physical activity among 979 grade 7 students (mean age=12.7 [0.5] years at baseline) were compared during and after the ban in seven schools that fully implemented the ban, and three schools that did not implement the ban fully. On average, schools offered 18.0 (SD=5.1) ECAs during a no-ban school year. Students attending full implementation schools were significantly more likely than students in nonimplementation schools to be active after the ban ended (odds ratio for being active=1.89 [95% confidence interval: 1.39, 2.58]). They also increased the number of physical activities in which they participated (coefficient=4.04; SE=1.01). Ending a teachers' ban on sports-related ECAs was associated with increased involvement in physical activity among secondary school students.

    Although it is intuitive and morally compelling that the worst forms of child labour should be eliminated, banning them in poor countries is unlikely to be welfare improving and can come at the expense of human capital accumulation. We show that the existence of harmful forms of child labour, in fact, has an economic role: it helps keep wages for child labour high enough to allow human capital accumulation. Therefore, unless appropriate mechanisms are designed to mitigate the decline in child...

    2016-09-27

    Resource nationalism encompasses a broad range of political and economic actions taken by Governments to regulate the extraction of natural resources within their borders. Policies such as increased tariffs or export restrictions can have far-reaching economic effects on international trade. As the Governments of several developing countries consider enacting nationalistic policies, an examination of the 2014 mineral export ban in Indonesia provides an instructive example of the possible impacts of resource nationalism. Significant changes in the production and trade of unprocessed (that is, ores and concentrates) and processed (that is, refined metal) aluminum, copper, and nickel before and after the export ban form the basis of this study.The U.S. Geological Survey (USGS) National Minerals Information Center (NMIC) tracks production and trade of mineral commodities between producer and consumer countries. Materials flow studies clarify the effects of an export ban on different mineral commodities by assessing changes in production, processing capacity, and trade. Using extensive data collection and monitoring procedures, the USGS NMIC investigated the effects of resource nationalism on the flow of mineral commodities from Indonesia to the global economy.

  19. DTCA of prescription medicines in the European Union: is there still a need for a ban?

    Science.gov (United States)

    Poser, Mareen

    2010-12-01

    The pharmaceutical sector is one of the main markets in the European Union. The consumption of medicines is high and steadily increasing. However, the pharmaceutical market is subject to a wider range of restrictions than almost any other sector. The restrictions mainly apply to information provision and advertising practice within the community. One of the main features in pharmaceutical regulation is the ban on direct-to-consumer advertising (DTCA) of prescription medicines. However, an abolition of the ban is controversial in the European Community, especially as the pharmaceutical industry keeps pleading for its ability to use the highly effective marketing strategy of DTCA to promote prescription medicines to the general public. Such advertising is only allowed in two jurisdictions in the world, New Zealand and the United States. In both systems the impact of DTCA on the consumer and the economy has been subject to research. The outcome of these studies is outlined in this article. Since the European Commission has provided a new proposal to amend the current information practice regarding prescription medicines in 2008 (European Commission, Proposal for a Directive of the European Parliament and of the Council Amending, as Regards Information to the General Public on Medicinal Products Subject to Medical Prescription, Directive 2001/83/EC on the Community Code Relating to Medicinal Products for Human Use, COM/2008/0663 final) it is time to examine different options to regulate the provision of information and discuss the need for a ban of DTCA.

  20. Gender and Power Dynamics in Transnational Marriage Brokerage: The Ban on Commercial Matchmaking in Taiwan Reconsidered

    Directory of Open Access Journals (Sweden)

    Hsun-Hui Tseng

    2015-06-01

    Full Text Available Taiwan attracted a considerable number of marriage migrants from Southeast Asia and China through brokers in the late 1990s and early 2000s. With widely circulated, sensational news stories about foreign spouses being abused and advertisements of foreign brides as objects for sale, women involved in the business were gradually seen by the public as victims of transnational marriage brokerage. Under pressure from some women’s groups in Taiwan and the anti-trafficking campaign in the international community, the Taiwanese government eventually banned transnational commercial matchmaking in 2008. This article examines the gender politics behind the ban by reviewing the debate over this policy. It also provides an ethnographic study of women’s power relationships with other parties involved in the marriage business. By exposing the market and cultural logic that made this business blossom, this article challenges the binaries of perpetrator/victim and exploitation/freedom in the dominant representations of the transnational marriage market. It calls for a transnational and transclass perspective to understand these women’s “active submission” to the market and concludes that, without this consideration, the enforcement of the 2008 ban ends up serving only to save the international reputation of the host country and fulfill the liberal middle-class imaginary of moral order of the host society, rather than solving women’s problems per se.

  1. Banning smoking in parks and on beaches: science, policy, and the politics of denormalization.

    Science.gov (United States)

    Bayer, Ronald; Bachynski, Kathleen E

    2013-07-01

    Campaigns to limit tobacco use started in the 1970s and have led to bans on public smoking, which have been extended to parks and beaches. A review of state and local statutes shows that during 1993-2011, smoking was banned in 843 parks and on 150 beaches across the United States. Three justifications for these restrictions have been invoked: the risk of passive smoke to nonsmokers, the pollution caused by cigarette butts, and the long-term risks to children from seeing smoking in public. Our analysis of the evidence for these claims found it far from definitive and in some cases weak. What, then, accounts for the efforts to impose such bans? We conclude that the impetus is the imperative to denormalize smoking as part of a broader public health campaign to reduce tobacco-related illness and death. Although invoking limited evidence may prove effective in the short run, it is hazardous for public health policy makers, for whom public trust is essential.

  2. Impact of banning of two-stroke engines on airborne particulate matter concentrations in Dhaka, Bangladesh.

    2006-01-01

    Vehicular air pollution is common in growing metropolitan areas throughout the world. Vehicular emissions of fine particles are particularly harmful because they occur near ground level, close to where people live and work. Two-stroke engines represented an important contribution to the motor vehicle emissions where they constitute approximately half of the total vehicle fleet in Dhaka city. Two-stroke engines have lower fuel efficiency than four-stroke engines, and they emit as much of an order of magnitude and more particulate matter (PM) than four-stroke engines of similar size. To eliminate their impact on air quality, the government of Bangladesh promulgated an order banning all two-stroke engines from the roads in Dhaka starting on December 31, 2002. The effect of the banning of two-stroke engines on airborne PM was studied at the Farm Gate air quality-monitoring station in Dhaka (capital of Bangladesh), a hot spot with very high-pollutant concentrations because of its proximity to major roadways. The samples were collected using a "Gent" stacked filter unit in two fractions of 0-2.2 microm and 2.2-10 microm sizes. Samples of fine and coarse fractions of airborne PM collected from 2000 to 2004 were studied. It has been found that the fine PM and black carbon concentrations decreased from the previous years because of the banning of two-stroke engine baby taxies.

    Fine particles in hospitality venues with insufficient smoking bans indicate health risks from passive smoking. In a random sample of Viennese inns (restaurants, cafes, bars, pubs and discotheques) effects of partial smoking bans on indoor air quality were examined by measurement of count, size and chargeable surface of ultrafine particles (UFPs) sized 10-300 nm, simultaneously with mass of particles sized 300-2500 nm (PM2.5). Air samples were taken in 134 rooms unannounced during busy hours and analyzed by a diffusion size classifier and an optical particle counter. Highest number concentrations of particles were found in smoking venues and smoking rooms (median 66,011 pt/cm(3)). Even non-smoking rooms adjacent to smoking rooms were highly contaminated (median 25,973 pt/cm(3)), compared with non-smoking venues (median 7408 pt/cm(3)). The particle number concentration was significantly correlated with the fine particle mass (Plaw in Austria is ineffective to protect customers in non-smoking rooms of hospitality premises. Health protection of non-smoking guests and employees from risky UFP concentration is insufficient, even in rooms labeled "non-smoking". Partial smoking bans with separation of smoking rooms failed.

    Exposure to secondhand smoke occurs primarily in the home due to passage of smoke-free legislation. Creation of a total household smoking ban can reduce associated health conditions such as asthma, lung cancer, heart disease and stroke. This paper describes the results of a randomized control trial of a minimal intervention to create smoke-free homes. 2-1-1 callers were invited to participate in the trial and were randomized to an intervention (mailings and a coaching call) or a control group (no intervention). We assessed reach, dose, fidelity, and receptivity to the intervention through program records and a 3-month follow-up survey with intervention participants. For the intervention materials, materials were mailed to 244 participants (99.2%) and 227 participants (92.3%) received the coaching call intervention. 92.3% received all intervention components. Participants who had full household bans at 3 months were more likely to conduct behaviors leading to a smoke-free home (i.e., making a list of reasons, having a family talk, posting a pledge) than were those with no/partial ban. The intervention materials also were rated higher in relevance and usefulness by non-smokers than smokers. Results demonstrate that this minimal intervention had high fidelity to the delivery of components and relatively high receptivity. PMID:26795538

    2017-12-01

    The Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) has developed the capability to run high-resolution atmospheric transport modelling by employing WRF and Flexpart-WRF. This new capability is applied to simulate the impact of stack emission data on simulated concentrations and how the availability of such data improves the overall accuracy of atmospheric transport modelling. The presented case study focuses on xenon-133 emissions from IRE, a medical isotope production facility in Belgium, and air concentrations detected at DEX33, a monitoring station close to Freiburg, Germany. The CTBTO is currently monitoring the atmospheric concentration of xenon-133 at 25 stations and will further expand the monitoring efforts to 40 stations worldwide. The incentive is the ability to detect xenon-133 that has been produced and released from a nuclear explosion. A successful detection can be used to prove the nuclear nature of an explosion and even support localization efforts. However, xenon-133 is also released from nuclear power plants and to a larger degree from medical isotope production facilities. The availability of stack emission data in combination with atmospheric transport modelling can greatly facilitate the understanding of xenon-133 concentrations detected at monitoring stations to distinguish between xenon-133 that has been emitted from a nuclear explosion and from civilian sources. Newly available stack emission data is used with a high-resolution version of the Flexpart atmospheric transport model, namely Flexpart-WRF, to assess the impact of the emissions on the detected concentrations and the advantage gained from the availability of such stack emission data. The results are analyzed with regard to spatial and time resolution of the high-resolution model and in comparison to conventional atmospheric transport models with and without stack emission data.

    Temporal change in tributyltin (TBT) levels in Jinhae Bay, which has various TBT sources, was investigated in water, sediments, and oysters from 2003 to 2013 after its total ban in South Korea. The seawater TBT levels decreased over 500-fold from 1995/97 to 2008/09. The oyster TBT levels were about fourfold lower in 2012/13 than in 1995/97. However, the sediment TBT levels did not significantly change, even 10 years after the partial TBT ban on small ships and 7 years after the total TBT ban on all oceangoing vessels in Korea. The total ban of TBT use effectively reduced water and oyster TBT levels in Jinhae Bay, but TBT levels in water, oysters, and sediment remained above the global environmental quality standards established to protect marine organisms.

    The temporal changes in the frequency and degree of imposex and tributyltin (TBT) levels in gastropod (Reishia clavigera) were evaluated in Jinhae Bay, 5 and 10 years after the total ban on TBT usage in South Korea. The frequency and degree of imposex decreased significantly after the ban, accompanied by an increase in the female-to-male ratio. The TBT concentrations in R. clavigera also decreased significantly after the ban. There were good correlations between the TBT concentration in rock shell and both the degree of imposex and the female-to-male ratio. The total TBT ban effectively reduced the TBT levels and the frequency and degree of imposex in R. clavigera. However, the current low exposure level in the study area is still sufficient to cause imposex in R. clavigera. More time is needed to reduce the TBT levels to levels that do not have adverse biological effects on R. clavigera.

  8. Striving for quality use of medicines: how effective is Australia's ban on direct-to-consumer prescription medicine advertising?

    The potential for both positive and negative effects arising from direct-to-consumer advertising of prescription medicines challenges health policymakers to develop regulatory schemes which selectively capture the positive aspects of the practice. Australia has dealt with this quandary by banning the practice, while New Zealand and the United States permit it. However, in recent times pharmaceutical companies have been increasingly successful in introducing promotional materials into the Australian market. This article demonstrates that the Australian ban is consistent with striving for the major policy goal of quality use of medicines, thus providing the basis for arguing that solutions to strengthen the ban against the identified threats ought to be implemented. Quality use of medicines can be most effectively achieved via the combined effect of the strengthened ban and the mimicking of the limited positive aspects of direct-to-consumer advertising by government provision of non-promotional information to consumers.

    Active and passive smoking are well-known causes of disease, including respiratory and cardiovascular disease and cancer. In 2004 the Dutch government introduced new legislation to regulate smoking in the workplace. However, smoking is still allowed in hotels, bars and restaurants, despite the fact that two-thirds of the Dutch population support a total ban on smoking in public places. Several other European countries and American states have banned smoking in public places. Studies performed in these regions show that the new smoking regulations have had no negative economic effects. Moreover, various studies have shown that smoking bans have a positive impact on public health, even in the short-term, including a significant decrease in respiratory and cardiovascular disease. There is therefore no reason to continue to exclude hotels, bars and restaurants from the smoking ban in all public places in The Netherlands.

    Full Text Available Basically, construction of road pavement has 2 (two types, are rigid pavement and flexible pavement. Rigid pavement has many advantages: the design is simple, the maintenance is easy and it is suitable for heavy load traffic as well as for sub grade with low CBR value However, the main disadvantage of rigid pavement is its inflexibility because the flexural strength of concrete is low. To increase the flexibility of concrete, adding elastic material (waste tire into concrete mixture is needed. This is very possible, because waste tire has high modulus of elasticity value and low density. This research is conducted to find the influence of waste tire fiber addition towards the increase of flexural strength and compressive strength of rigid pavement. This research uses tire shreds 4 mm x 4 mm x 60 in mm size which are mixed randomly into various concentrations. Concrete mechanic behaviors, flexural strength and compressive strength, are measured by testing cylinder and beam concrete specimens. The research results show that the addition of waste tire fiber can increase flexural strength of concrete up to 20.84% and compressive strength of concrete up to 4.73% higher than normal concrete when the waste tire fiber content is 0.75%.

    The aim of the study was to investigate possible effects of a total smoke-ban in Norwegian bars and restaurants (introduced on June 1st 2004) on employees' job satisfaction. A national representative sample was randomly selected from the public registry of all companies in the hospitality business. A baseline survey was conducted in May 2004, follow-up measurements were performed in September/October 2004 and May 2005. Altogether, 1525 employees agreed to participate in the baseline survey. Among respondents at baseline, 894 (59.4%) remained in the sample at the first follow-up and 758 (49.7%) at the second follow-up. Analysis of variance for repeated measures revealed a significant three-way interaction between personal smoking behaviour, attitudes towards the ban before it was enacted and time from baseline to the second follow-up. A small decline in job satisfaction was found between baseline and the first follow-up among employees who were daily smokers and had a negative attitude towards the ban. There was, however, an increase in job satisfaction between the first and second follow-up among the others (non-smokers and smokers with a positive attitude towards the ban). While job satisfaction was higher among smokers with negative attitudes towards the ban than among other employees before the ban entered into force, the opposite was the case one year later. The work environments in bars and restaurants seem to have changed towards being more satisfactory for non-smokers and smokers with positive attitudes towards the ban before it was enacted. In contrast, a small but persisting worsening of job satisfaction was found among employees that were daily smokers and had a negative attitude towards the ban.

    Germany's 16 states regulate smoking differently within health protection principles laid down in the federal law. All state smoke-free laws in Germany have undergone at least one change since taking effect. We systematically review federal and state laws regulating smoking, as well as petitions, popular initiatives and referenda that aimed at changing statutory smoking bans. Data generated through the systematic review were correlated with state smoking rates. The protection from the dangers of secondhand smoke is the primary motive for smoking bans in Germany. The first smoke-free laws affecting smoking in pubs, restaurants and several other public places were introduced in 2007. In 2008, the Federal Constitutional Court of Germany ruled in a leading decision on the smoke-free laws of two states that some common smoking ban exemptions of the introduced smoke-free laws violate the basic right to freely exercise a profession and mandated revisions. All states but Bavaria and Saarland, whose smoking bans were more and less comprehensive than those judged by the constitutional court, respectively, needed to change the smoking ban exemptions to reconcile their smoke-free laws with the constitution. Direct democracy initiatives to change smoking bans were only successful in Bavaria in 2010, but a total of 15 initiatives by citizens' or interest groups attempted to influence non-smokers protection legislation through direct democratic procedures. Early ratification of a smoking ban in a federal state correlates with a higher reduction in the smoking rate from 2005 to 2009 (Spearman's ρ = 0.51, p = 0.04). The federal government structure and direct democratic participation in smoke-free legislation in Germany has produced a diversity of local smoking bans and exemptions.

    Background The tobacco industry uses point-of-sale (POS) advertising, promotion, and product display to increase consumption of its products among current users, to attract new consumers, and to encourage former customers to resume tobacco use. As part of a comprehensive tobacco control effort, Russia—having one of the highest tobacco use prevalence rates in the world—enacted legislation that banned tobacco POS advertising, effective November 15, 2013, and banned the display of tobacco and the sale of cigarettes in kiosks, effective June 1, 2014. Objective The objective of the study was to evaluate the implementation of the national law by assessing the state of POS advertising, promotion, and product display, and sales in kiosks across Russia. Methods Two waves of observations were conducted to measure compliance with the POS restrictions: wave 1 took place in April-May 2014 after the advertising ban was in effect and again in August-September 2014 after the display ban and elimination of tobacco sales in kiosks came into effect. Observations were conducted by local trained staff that traveled to 5 populous cities in different regions of Russia (Moscow, St. Petersburg, Kazan, Ekaterinburg, and Novosibirsk). Staff followed a published POS evaluation protocol and used mobile phones to collect data. Observations were conducted in a roughly equal number of supermarket chains, convenience stores, and kiosks. Observed items included advertising at POS, product displays, and cigarette sales in kiosks. Results Observations were made in 780 venues in wave 1 and in 779 revisited venues in wave 2. In wave 1, approximately a third of supermarkets and convenience stores (34.2%, 184/538) were advertising cigarettes using light boxes, and over half of observed venues (54.3%, 292/538) had signage such as banners or shelf liners that used colors or images related to cigarette brands. Product displays were common in wave 1. In wave 2, compliance with advertising restrictions

    Gap Resolution is a software package that was developed to improve Newbler genome assemblies by automating the closure of sequence gaps caused by repetitive regions in the DNA. This is done by performing the follow steps:1) Identify and distribute the data for each gap in sub-projects. 2) Assemble the data associated with each sub-project using a secondary assembler, such as Newbler or PGA. 3) Determine if any gaps are closed after reassembly, and either design fakes (consensus of closed gap) for those that closed or lab experiments for those that require additional data. The software requires as input a genome assembly produce by the Newbler assembler provided by Roche and 454 data containing paired-end reads.

    Despite the great progress made towards smoke-free environments, only 9% of countries worldwide mandate smoke-free restaurants and bars. Smoking was generally not regulated in restaurants and bars in China before 2008. This study was designed to examine the public attitudes towards banning smoking in these places in China. A convenience sample of 814 restaurants and bars was selected in five Chinese cities and all owners of these venues were interviewed in person by questionnaire in 2007. Eighty six percent of current nonsmoking subjects had at least one-day exposure to secondhand smoke (SHS) at work in the past week. Only 51% of subjects knew SHS could cause heart disease. Only 17% and 11% of subjects supported prohibiting smoking completely in restaurants and in bars, respectively, while their support for restricting smoking to designated areas was much higher. Fifty three percent of subjects were willing to prohibit or restrict smoking in their own venues. Of those unwilling to do so, 82% thought smoking bans would reduce revenue, and 63% thought indoor air quality depended on ventilation rather than smoking bans. These results showed that there was support for smoking bans among restaurant or bar owners in China despite some knowledge gaps. To facilitate smoking bans in restaurants and bars, it is important to promote health education on specific hazards of SHS, provide country-specific evidence on smoking bans and hospitality revenues, and disseminate information that restricting smoking and ventilation alone cannot eliminate SHS hazards.
