    Recent events, involving inter alia France and Denmark, have stimulated renewed interest in the introduction of different forms of border controls at the internal borders within the European Union. These border control measures are aimed at checking either persons or goods or both. Against...... the background of these events, this article analyses the existing rules regulating controls of persons and goods, and explores how these rules may or may not stand in the way of introducing border controls at the European Union’s internal borders. These events have resulted in a call for reforms of the current...

  2. Measures to detect and control radioactive contaminated metallurgical scrap at border checkpoints in Poland

    International Nuclear Information System (INIS)

    Smagala, G.

    1999-01-01

    The issue of radioactive contaminated metallurgical scrap has never received a high priority in Poland and in the international community. Since the dissolution of the former Soviet Union a higher attention has been given to the problem. Poland which is located between the West and East Europe has the obligation to develop and implement an effective prevention and detection system. The reasons to increase national control and detection system at the border checkpoints in Poland are to avoid the following risks: post Chernobyl contamination transports of commodities; transport of contaminated metal scrap; transfer of radioactive waste for their disposal or utilization; high risk of becoming a transit country of illicit trafficking of nuclear materials and radioactive sources. In order to avoid the above-mentioned risks, Poland initiated in 1990, a deployment of the portable radiation devices at the border checkpoints and, as of 1998, the number of installed instruments exceeded a hundred. This paper presents Poland's activities to detect contaminated scrap at its border checkpoints. (author)

    Full Text Available In the early stages of Pandemic (H1N1 2009, border control measures were taken by quarantine stations to block the entry of infected individuals into Japan and community containment measures were implemented to prevent the spreading. The objectives of this study were to describe these measures and the characteristics of infected individuals, and to assess the measures' effectiveness.Border control and community containment measures implemented from April to June (Period I: April 28-May 21, Period II: May 22-June 18 2009 were described. Number of individuals identified and disease characteristics were analyzed. For entry screening, a health declaration form and an infrared thermoscanner were used to detect symptomatic passengers. Passengers indicated for the rapid influenza test underwent the test followed by RT-PCR. Patients positive for H1N1 were isolated, and close contacts were quarantined. Entry cards were handed out to all asymptomatic passengers informing them about how to contact a health center in case they developed symptoms. Nine individuals were identified by entry screening and 1 during quarantine to have Pandemic (H1N1 2009. Health monitoring by health centers was performed in period I for passengers arriving from affected countries and in period II for those who had come into contact with the individuals identified by entry screening. Health monitoring identified 3 infected individuals among 129,546 in Period I and 5 among 746 in Period II. Enhanced surveillance, which included mandatory reporting of details of the infected individuals, identified 812 individuals, 141 (18% of whom had a history of international travel. Twenty-four of these 141 passengers picked up by enhanced surveillance had been developing symptoms on entry and were missed at screening.Symptomatic passengers were detected by the various entry screening measures put in place. Enhanced surveillance provided data for the improvement of public health measures in

  4. Temporary reintroduction of border controls at French borders inside the Schengen Area

    2006-01-01

    Full Text: The limits of optical measurements are the subject to many recent works. It has been shown how by using non-classical photonic states, spatial resolution can exceed the diffraction limit [1]. The same states also improve interference measurements beyond the shot noise and up to the quantum Heisenberg limit [2]. On the other hand, a few methods have been suggested that improve the optical resolution by exploiting classical optical nonlinearities [3]. First, we will present a scheme that exploits the non-local quantum correlations of a second order entangled state produced by optical parametric down-conversion [4]. The scheme results with a non-classical state that can be used in quantum limited interferometry. It is also simply extendable to states of any photon number. Another method will be presented, where nonlinear measurements are induced by projecting the state of light onto the Fock space [5]. This process simulated optical nonlinearities up to the 7th order. We used those measurements to characterize the output of a standard polarization interferometer. Improved resolution was demonstrated, but a detailed analysis reveals the differences to the previous nonclassical approach

    These principles have been applied to our air ambulance system based from Lanseria International Airport. By combining preventative and control measures, there has been no breach in our infection control strategies, as evidenced by no growth noted on specific and random swabs even when more and more ”super bugs” are being identified in hospital. As an air ambulance service flying patients from various African countries, we have the responsibility to conduct our own ”Border Security” to keep our hospitals, patients, aircraft and crews clean and safe. In this presentation we will share our ”Border Security” principles and experiences with the audience.

  17. Border screening vs. community level disease control for infectious diseases: Timing and effectiveness

    Science.gov (United States)

    Kim, Sehjeong; Chang, Dong Eui

    2017-06-01

    There have been many studies of the border screening using a simple math model or a statistical analysis to investigate the ineffectiveness of border screening during 2003 and 2009 pandemics. However, the use of border screening is still a controversial issue. It is due to focusing only on the functionality of border screening without considering the timing to use. In this paper, we attempt to qualitatively answer whether the use of border screening is a desirable action during a disease pandemic. Thus, a novel mathematical model with a transition probability of status change during flight and border screening is developed. A condition to check a timing of the border screening is established in terms of a lower bound of the basic reproduction number. If the lower bound is greater than one, which indicates a pandemic, then the border screening may not be effective and the disease persists. In this case, a community level control strategy should be conducted.

    In Thailand's northwestern Tak province, contextual conditions along the border with Myanmar pose difficulties for TB control among migrant populations. Incomplete surveillance data, migrant patient mobility, and loss to follow-up make it difficult to estimate the TB burden and implement effective TB control measures. This multi-methods study examined tuberculosis, tuberculosis and human immunodeficiency virus co-infection, and multidrug-resistant tuberculosis treatment accessibility for migrants and refugees in Tak province, health system response, and public health surveillance. In this study we conducted 13 interviews with key informants working in public health or TB treatment provision to elicit information on TB treatment availability and TB surveillance practices. In addition we organized 15 focus group discussions with refugee and migrant TB, TB/HIV, and MDR-TB patients and non-patients to discuss treatment access. We analyzed the data using thematic analysis and created treatment availability maps with Google maps. The study identified surveillance, treatment, and funding gaps. Migrant TB cases are underreported in the provincial statistics due to jurisdictional interpretations and resource barriers. Our results suggest that TB/HIV and MDR-TB treatment options are limited for migrants and a heavy reliance on donor funding may lead to potential funding gaps for migrant TB services. We identified several opportunities that positively contribute to TB control in Tak province: improved diagnostics, comprehensive care, and collaboration through data sharing, planning, and patient referrals. The various organizations providing TB treatment to migrant and refugee populations along the border and the Tak Provincial Public Health Office are highly collaborative which offers a strong foundation for future TB control initiatives. Our findings suggest the need to enhance the surveillance system to include all migrant TB patients who seek treatment in Tak province and

  3. Managing Migration: Is border control fundamental to anti-trafficking and anti- smuggling interventions?

    Directory of Open Access Journals (Sweden)

    Rebecca Miller

    2013-09-01

    Full Text Available Over the last several decades, globalisation and a growing concern over security issues, including transnational crime and terrorism, has shaped migration policies and the priorities of states. As migration rose to the top of many government agendas, a rapid tightening and regularisation of borders ensued in an attempt to keep undesirable, high-risk migrants out of potential destination countries. Concomitantly, transnational crimes, such as trafficking in persons and the smuggling of migrants, have been increasingly defined as border security problems. This article examines the extent to which border control is fundamental to anti-trafficking and anti-smuggling interventions, situating the debate within the wider nexus of globalisation and the securitisation of migration. Based upon their work with the United Nations Office on Drugs and Crime (UNODC Regional Centre for Southeast Asia and the Pacific, the authors take the standpoint that given it is the sovereign right of each state to control its border and regulate migration, the human rights of migrants must be considered within this realpolitik. Clearly, though, this claim is highly political and contentious. In the article, we explore some of the tensions and contradictions that have emerged in this debate, and then develop an argument to suggest that it is possible for states to combine managed migration and strict border controls with the protection of human rights in the current context of globalisation.

    2013-06-01

    Full Text Available The increasing request for safety, security and environment protection at local and national level reveal the deficiency of the traditional surveillance and control centers to satisfy the needs and requirements of modern border control systems for homeland protection where land border is expected to be monitored as well as the maritime one. This is, for instance, the case of any land border affected by hidden immigration and/or illegal traffics as well as any small areas such as critical infrastructures or military/ civilian posts in forest or jungle environment characterized by vegetation. In such challenging environment, logistics constraints strongly recommend to have very low power devices able to operate months or years without maintenance. A such scenario should be the perfect place for implementing an Unattended Ground Sensors (UGS network making use FOliage PENetration (FOPEN radar for border control. The paper aims to present the basic characteristics and preliminary results of a Surveillance Unattended FOPEN (SUF radar suitable for detecting moving targets, people or vehicles, in dense forest environment.

  5. MIGRATION POLICIES AND STATE CONTROL IN ARGENTINA: EXPERIENCES OF VULNERABLE BOLIVIAN WOMEN WHO CROSS THE BORDERS

    Directory of Open Access Journals (Sweden)

    Cynthia Pizarro

    2015-01-01

    Full Text Available This paper analyzes the way in which migration policies impact in the trajectories of Bolivian women who live and work in the outskirts of the main cities of Argentina. It focuses on three cases representative of the experiences of women laborers who, coming from the poorest rural areas of Bolivia, crossed the international border when Argentine migration policy was very restrictive. It shows that symbolic and socio-economic borders keep on excluding them, as well as other labor migrants, within the Argentine territory even when the current Migration Law enacted in 2004 is more inclusive, since it grants human and social rights to the migrants. It highlights the way in which particular state control mechanisms operate nowadays both at the international border and within the Argentine territory, and analyses the difficulties that these women experience due to their positions of class, ethnic, gender, nationality and migratory status. It remarks that despite the changes in the immigration policy of Argentina, state policies keep on controlling labor migrations in accordance with the paradigm of the governance of migration. It also analyses the strategies that these women develop in order to sort out state control policies. Therefore, it considers that they are active agents even though they still have feelings of fear and trauma associated with the crossing of borders.

  6. The “Fake Marriage” Test in Taiwan: Gender, Sexuality, and Border Control

    Directory of Open Access Journals (Sweden)

    Mei-Hua Chen

    2015-06-01

    Full Text Available According to many reports, migrant sex workers often use marriages of convenience to cross national borders in order to avoid laws criminalizing commercial sex in many destination countries. Taiwan is one of the countries developing strategies to prevent this illicit migration, particularly through the application of a fake marriage test. Based on in-depth interviews with eighteen Chinese migrant sex workers and thirteen officers of Taiwan’s National Immigration Agency (NIA, this article argues, first, that the discourse of “national security” has been widely drawn on to justify Taiwan’s rigid border control at the expense of stigmatized Chinese prostitutes who have been scapegoated. Border control is therefore not only racialized or classed but also sexualized, to the extent that all Chinese migrant women are considered potential prostitutes. Second, this article reveals how the exclusion of and hostility toward Chinese sex workers are simultaneously linked with a gender regime that seeks to exclude Chinese spouses who deviate from Taiwanese gender and social norms. The border is therefore a contested site where gender, sexuality, and nationality are interwoven.

  7. Concepts on border control of the immigration movements supporters in the Great Britain

    Directory of Open Access Journals (Sweden)

    Mariya D. Lada

    2016-01-01

    Full Text Available Due to the current activization of immigration movements towards Europe the problem of border control and possibility of free migration has become especially topical and critical in political and social discussion in the countries of the European Union and Great Britain in particular. The arguments of free border supporters in modern Great Britain are reviewed in terms of the research of works by Teresa Hayter. Teresa Hayter – scientist, publicist, active participant of the antiracist movement and one of the most radical supporters of «free migration» in Great Britain Her views were fully presented in the monograph «Open borders: case against immigration controls» (first edition 2000, second – 2004, third – 2015. The key arguments of the supporters of active migration movements include the very idea of such movements being objectively and historically predetermined, while their control or preventing is a form of discrimination. Teresa Hayter debunks a range of myths and stereotypes concerning this problem, in particular the effectiveness of repressive methods of control and absolutely negative consequences for the population and country caused by these movements. The researcher states that the only way to ensure that the refuges are truly protected is to eliminate immigration control. Such sphere of government policy as immigration regulation and control is a form of racism. The majority of her arguments have moral and political context. On the other hand, they can be a special source of studying social discussion of the issue of free borders and migration processes in Great Britain.

    2008-01-01

    Full text: Prevention of illicit trafficking in radioactive and nuclear materials through state borders as well as the disperse of radioactive materials in urban area is a challenging task of national security departments in many countries. To solve this task, appropriate actions of personnel on-site equipped by radiation detectors such as fixed radiation portal monitors or mobile personal radiation detectors are required. However, users of radiation equipment such as Customs, Border Guard and Police Services often perform radiation control as additional responsibility to their main duties. Furthermore, these users have no sufficient expertise in radiation control and need real-time remote expert help to interpret readings of radiation equipment and expert support in decision making process. Polimaster has developed complete solution called Nuclear Protection Network system (NPNET) for high-effective radiation control on State Borders as well as inside a country. NPNET system intended for efficient interaction and on-line data exchange between a user, radiation control instrument, for example a personal radiation detector or radioisotope identifier, and remote Command Center. Availability of such system allows to solve more efficiently tasks of detection, localization and identification of ionizing radiation sources, to properly interpret false alarms (e.g. at detention of a passenger having passed radio-therapy etc.) and effectively prevent illicit trafficking radioactive and nuclear materials. The NPNET system can cover territory as large as city or even a state and provides assistant of infinite number of independent user groups. NPNET has a module structure and could be easily adapted to any specific user's requirements. Thus, the radiation mobile system NPNET is an effective tool for prevention of illicit trafficking of nuclear and radioactive materials and is recommended for use by Border guards, Customs, Securities and emergency situations services.

    2015-01-01

    Malaria control along the Vietnam–Cambodia border presents a challenge for both countries' malaria elimination targets as the region is forested, inhabited by ethnic minority populations, and potentially characterized by early and outdoor malaria transmission. A mixed methods study assessed the vulnerability to malaria among the Jarai population living on both sides of the border in the provinces of Ratanakiri (Cambodia) and Gia Lai (Vietnam). A qualitative study generated preliminary hypotheses that were quantified in two surveys, one targeting youth (N = 498) and the other household leaders (N = 449). Jarai male youth, especially in Cambodia, had lower uptake of preventive measures (57.4%) and more often stayed overnight in the deep forest (35.8%) compared with the female youth and the adult population. Among male youth, a high-risk subgroup was identified that regularly slept at friends' homes or outdoors, who had fewer bed nets (32.5%) that were torn more often (77.8%). The vulnerability of Jarai youth to malaria could be attributed to the transitional character of youth itself, implying less fixed sleeping arrangements in nonpermanent spaces or non-bed sites. Additional tools such as long-lasting hammock nets could be suitable as they are in line with current practices. PMID:26283747

  10. How recruitment, intraspecific interactions, and predation control species borders in a tidal estuary.

    Leonard, George H; Ewanchuk, Patrick J; Bertness, Mark D

    1999-03-01

    We examined the relative contribution of recruitment, intraspecific species interactions, and predation in controlling the upper intertidal border of the northern acorn barnacle, Semibalanusbalanoides, in a tidal estuary in Maine. We hypothesized that the contracted border at sites that experienced low tidal currents was due to flow-mediated recruitment that resulted in reduced survival due to the absence of neighbor buffering of thermal stress (i.e., positive intraspecific interactions). We tested this hypothesis by manipulating the density of recently settled barnacles and their thermal environment in a field experiment. Counter to our original hypothesis, barnacles with neighbors suffered severe mortality at low-flow sites. When density-dependent predation by the green crab (Carcinusmaenus) was experimentally eliminated, however, we did detect evidence for positive interactions at the low-flow sites but not at the high-flow sites. In spite of the close proximity of the sites, maximum daily rock temperatures at the low-flow sites were slightly, but consistently, greater than those at high-flow sites. Our findings suggest that the upper intertidal border of S. balanoides in the Damariscotta River is limited at low-flow sites by a combination of reduced recruitment, elevated mortality from thermal stress and enhanced predation by green crabs. More generally, our findings highlight how physical stress and predation interact to alter the nature of density-dependent species interactions in natural assemblages.

  12. Airport Casualties: Non-Admission and Return Risks at Times of Internalized/Externalized Border Controls

    Directory of Open Access Journals (Sweden)

    Maybritt Jill Alpes

    2015-09-01

    Full Text Available This article analyzes what can happen to forced returnees upon arrival in their country of nationality. Subjective configurations of state agents in the Global South have created return risks, which in turn transform subjectivities of post-colonial citizens. The article contributes to this Special Issue by tracing repercussions of the externalization and internalization of border controls. In the case of Cameroon, these connections have resulted in the criminalization of emigration. Aspiring migrants are prosecuted if their departure projects fail to respect the entry requirements of countries in the Global North. The article is based on research conducted in Douala, Cameroon, in the form of discussions with control agents at the international airport, investigations at a prison, a review of related case law, police registers and interviews with Cameroonians returnees (November 2013–January 2014. Border controls and connected anti-fraud programs suppress family-based forms of solidarity and allow only for subjectivities rooted in state-managed forms of national identity. The article illustrates how efforts to combat fraud fuel corruption in returnees’ social networks, whereby, instead of receiving remittances, families in emigration countries have to mobilize financial resources in order to liberate returnees from police stations or prison complexes. Migration related detention of nationals in the Global South highlights the growing significance of exit controls in migration management.

This study presents descriptive findings on a new measure, the Border Community & Immigration Stress Scale (BCISS). Methods The data were from two community surveys as part of community based participatory projects conducted in the Southwestern US border region. This scale includes stressful experiences reflected in extant measures, with new items reflecting heightened local migration pressures and health care barriers. Results Stressors representing each main domain, including novel ones, were reported with frequency and at high intensity in the predominantly Mexican-descent samples. Total stress was also significantly associated with mental and physical health indicators. Discussion The study suggests particularly high health burdens tied to the experience of stressors in the US border region. Further, many of the stressors are also likely relevant for other communities within developed nations also experiencing high levels of migration. PMID:22430894

  16. Examining the Body through Technology: Age disputes and the UK border control system

    2013-09-01

    Full Text Available In an effort to ascertain whether certain migrants and refugees have been telling the ‘truth’ about their age, the UK border control system has, in the past, relied on the use of skeletal x- ray to estimate the applicant’s age, and in recent years has sought to use dental x-ray for the same purpose. However using x-ray for age assessment purposes has been criticised as inaccurate in providing a reasonable estimate of age and as an unnecessary medical risk, which infringes the human rights of the applicant. This is particularly pertinent in the case of children who are victims of trafficking and unaccompanied young people who may be vulnerable to exploitation, because if declared as children, they can access a higher level of care and protection under childcare law. The article argues that the deferment to the use of x-ray to reveal the ‘truth’ in age disputes is evidence that the border control system is more concerned with keeping ‘undesirable’ people out of the UK than observing the human rights of the vulnerable people who come into contact with the system.

    Full Text Available Mergers and acquisitions are basic channels for modern companies’ growth. With globalization speeding up, multinational companies increasingly take on M_A activities to strengthen global market positions and raise competitiveness. In recent years, M_A activities have played an important role in Chinese companies. Financial risk is inherent to M_A processes in cross-border companies. Also, more than 50% of Chinese companies did not achieve their M_A goals. Therefore, recognizing and controlling financial risk is essential. This paper analyses the financial risk from different perspectives and then provides suggestions by analysing a typical M_A case: Bohai Leasing merger with Seaco Company. Complete due diligence and clear M_A strategies, combination of various financing instrument, strategic paying methods and finance integration are some ways for controlling and decreasing finance risk.

    Full Text Available In the framework of the C-BORD project of the H2020 programme to provide a safety chain for container inspection at border control points, CEA-DAM is involved to develop an identification method of Special Nuclear Material. Using active interrogation the main purpose is to specifically discriminate fissile actinides from fertile ones through the detection of γ-rays emitted by very short-lived isomers. We present here the interdependance of such a project with nuclear data. We first introduce the SNM identification method. Then, will be detailed the needs in nuclear data and first yields of specific short-lived isomers of 252Cf spontaneous fission. Perspectives and conclusions will end the article.

  3. The limits of European data protection law in EU border control

    2015-12-01

    Full Text Available In the 1980s, the EU began collecting the personal data of people arriving from third countries in order to control migratory flows within the EU. However, since the 9/11 attacks function creep has led to this information, which was originally collected for EU border management, being used by police authorities. Information systems such as SIS, VIS, CIS and Eurodac have been amending their own regulations to permit access by police authorities from the member states and Europol. This paper analyses the potential conflict arising from these practises and the fundamental right to data protection in the EU. First, general and sectoral data protection rules applicable to the data processed by SIS, VIS, CIS and Eurodac will be examined. After that, this study will assess whether allowing law enforcement authorities to access such EU information systems could violate the EU principles of necessity and purpose limitation.

  4. Border control for stowaway alien species should be prioritised based on variations in establishment debt.

    2016-09-15

    Border control is one of the major approaches used by countries to limit the number of organisms introduced as stowaways. However, it is not feasible to inspect all passengers, cargo and vehicles entering a country, and so efforts need to be prioritised. Here we use South Africa as a case study to assess, based on tourism and trade data and climate matching techniques, the number of stowaway species that might be introduced ('colonisation pressure') and the likelihood that once introduced, these organisms will establish ('likelihood of establishment'). These results were used to explore how the number of species that are likely to establish ('establishment debt') varies across donor regions and seasons. A simple theoretical model was then used to compare four strategies for prioritising border control inspections: no prioritisation; based on colonisation pressure; based on likelihood of establishment; and based on both colonisation pressure and likelihood of establishment. Establishment debt was greatest in southern hemisphere spring and autumn when South Africa is climatically similar to northern hemisphere countries with which there are strong, consistent trade and tourism links (i.e. colonisation pressure varied little seasonally, but likelihood of establishment did vary across the seasons). Prioritising inspections based on both colonisation pressure and the likelihood of establishment was clearly the most effective strategy, with this strategy detecting at least 6% more potential invaders than the other strategies. While there are many practical limitations to the implementation of such prioritised inspection strategies, the results highlight the importance of national and regional studies of establishment debt.

    The implementation of climate policies in the US and EU in light of uncertainties about future international climate policy has shifted attention to two interrelated concerns, namely competitiveness and carbon leakage. Although various policy measures are available to address these concerns, there has been much discussion about one such measure in particular: the use of offsetting measures at the border. This article compares policy discussions in the US and the EU on how to address competitiveness and carbon leakage concerns, with a focus on the role of import-related border adjustment measures. It analyses the kinds of measures that so far have been put forward with a view to addressing competitiveness and carbon leakage; compares the approaches to the problems in the US and the EU; and provides a preliminary discussion of international cooperation on border adjustment measures. It concludes that two kinds of cooperation are needed between the EU and the US - not only cooperation through formal international negotiations, but also cooperation through international learning processes, in which the EU and the US learn from each other about design and implementation issues as they develop their respective cap-and-trade systems.

    Photographic identity documents (IDs) are commonly used despite clear evidence that unfamiliar face matching is a difficult and error-prone task. The current study set out to examine the performance of seven individuals with extraordinary face recognition memory, so called "super recognisers" (SRs), on two face matching tasks resembling border control identity checks. In Experiment 1, the SRs as a group outperformed control participants on the "Glasgow Face Matching Test", and some case-by-case comparisons also reached significance. In Experiment 2, a perceptually difficult face matching task was used: the "Models Face Matching Test". Once again, SRs outperformed controls both on group and mostly in case-by-case analyses. These findings suggest that SRs are considerably better at face matching than typical perceivers, and would make proficient personnel for border control agencies.

    2003-01-01

    In our department, in the last years, a new line of production has been developed devoted to the radioactivity measurements (portal monitor, gamma source detector, neutron monitor). Instruments of different design (hand-held, portals or steady-state) are intended for detection and locating of radioactive sources. Monitors are intended to detect radioactive and special nuclear materials in vehicles, pedestrians, luggage, as well as for illegal traffic prevention of radioactive sources. Monitors provide audio and visual alarm signals when radioactive and/or special nuclear materials are detected. Neutron dosimeters are designed for the determination of dose equivalent rate around neutron generators or sources. All devices can be recommended for use to officers of customs, border guard and emergency services, civil defense, fire brigades, police and military departments, nuclear research or power facilities. Incorporating micro controllers and new design, our products span almost all the spectra of radioactivity detection (gamma, beta, X and neutrons). No special knowledge is needed to operate these instruments as all service functions are performed automatically (self-tests, background updating and threshold calculation). The Portal monitor is intended to be a checkpoint in contamination control or in unauthorized traffic of radioactive materials. The portal monitor can be installed both in open, unprotected to environmental conditions areas or in enclosed areas. It may be used at pedestrian cross border points, at check points of Nuclear Power Plants, enterprises of nuclear industry, weapons manufacturing and storage plants, nuclear waste disposal and storage sites, at the entrances to steel plants, the post-offices and airports, the governmental offices, banks, private companies etc. The monitor provides audio alarming signals when radioactive and/or special nuclear materials are detected. The monitor consists in a portal frame, which sustains 5 detectors. Each

    1988-01-01

    Border installations cover all nuclear plants located near the border with a neighbouring state. However, the actual distance depends on the context. The distance can vary considerably. Also the prohibition on siting near a heavily populated area also defines the actual distance variably. The distance criteria may be modified by other factors of topography, prevailing climate and so on. Various examples which illustrate the problems are given. For example, the Creys-Melville nuclear power plant is 80km from Geneva and the Cattonam installation is 12km from the French border with Luxembourg and Germany. The Cattenom case is explained and the legal position within the European Institutions is discussed. The French licensing procedures for nuclear power stations are described with special reference to the Cattenom power plant. Border installations are discussed in the context of European Community Law and Public International Law. (U.K.)

    Directory of Open Access Journals (Sweden)

    Ana Lopez-Sala

    2017-06-01

    Full Text Available Over the last 25 years the southern maritime border of the European Union witnessed the interaction of considerable and increasingly complex irregular migration flows in the Mediterranean with the progressive construction and implementation of restrictive migration control policies by the European Union and its member states at their external borders. The article describes the evolving migration patterns and changes in migration routes both as a stimulus and a consequence of locally stepping up migration control at the emerging hotspots at different parts of the border, creating deviation effects in migration routes with alternative points of entry and higher costs and risks for migrants. Special attention is given to the impact of the 2015 refugee crisis on border management and the new challenges it poses to the asylum system and the protection of fundamental rights.

    2017-04-01

    Full Text Available Countries’ effective and efficient border security is becoming increasingly important in today’s global world of economy and trade. To ensure these, customs organisations are responsible for the prevention of illicit goods’ transportation across borders, particularly upon entry. The predicament of the customs administrations will soon be aggravated by both the increase of global trade and the trend towards 100% screening. It is therefore a goal to advance inspection methods to enable successful cargo handling, a scope towards which this research was aimed at. This work was carried out as part of the project ACXIS “Automated Comparison of X-ray Images for cargo Scanning” a European research project within the seventh framework programme answering the call SEC-2012.3.4-1: « Research on Automated Comparison of X-ray Images for cargo Scanning », to improve the process with the largest impact to trade flow: the procedures of freight X-ray scanning. As such, this project was focused on to implementing a manufacturer independent reference database for X-ray images of illicit and non-illicit cargo, developing procedures and algorithms in order to uniform X-ray images of different cargo scanners, and developing a training simulator for inspection officers and a toolbox enclosing several assisted and automated identification techniques for potentially illicit cargo.

  1. Metrics for border management systems.

    Energy Technology Data Exchange (ETDEWEB)

    Duggan, Ruth Ann

    2009-07-01

    There are as many unique and disparate manifestations of border systems as there are borders to protect. Border Security is a highly complex system analysis problem with global, regional, national, sector, and border element dimensions for land, water, and air domains. The complexity increases with the multiple, and sometimes conflicting, missions for regulating the flow of people and goods across borders, while securing them for national security. These systems include frontier border surveillance, immigration management and customs functions that must operate in a variety of weather, terrain, operational conditions, cultural constraints, and geopolitical contexts. As part of a Laboratory Directed Research and Development Project 08-684 (Year 1), the team developed a reference framework to decompose this complex system into international/regional, national, and border elements levels covering customs, immigration, and border policing functions. This generalized architecture is relevant to both domestic and international borders. As part of year two of this project (09-1204), the team determined relevant relative measures to better understand border management performance. This paper describes those relative metrics and how they can be used to improve border management systems.

    2008-01-01

    A new solution to control the illicit transportation of nuclear and radioactive materials is proposed and described. This solution consists in the creation of a system of gamma and gamma-neutron radiation monitors and fundamentally new software/hardware package RAVEN (Radiation Alarm and Video Event Notification) which integrates different type monitors in a single network. The main purpose of this system is to analyze and store data coming from radiation monitors, to process these data and to help the user to interpret them. This ensures the user's correct response to all the alarms triggered by radiation monitors and indicating the presence of radioactive and/or nuclear materials in scanned objects. The developed system can integrate fixed radiation monitors that can be installed in different sites within not only one country but in different sites worldwide in a single network. The system can be adapted to the local conditions and allows the user: (i) To detect minimum quantities of special nuclear and radioactive materials (specified by the national and international requirements) by their gamma and/or neutron radiation; (ii) To acquire, store and analyze digital data and video images related to cargos with radioactive materials crossing a state border or an object limits; (iii) To make these data accessible to users at different levels ensuring effective operation of both central alarm stations (state, regional or agency center) and local alarm stations (border cross points or object limits).

    Full Text Available The urge to increase the performance of company processes is ongoing. Surveys indicate however, that many companies do not measure the controlling performance with a defined set of key performance indicators. This paper will analyze three categories of controlling key performance indicators based on their degree of measurability and their impact on the financial performance of a company. Potential measures to optimize the performance of the controlling department will be outlined and put in a logical order. The aligning of the controlling activity with the respective management expectation will be discussed as a key success factor of this improvement project.

  4. The Enemy at the Gates: International Borders, Migration and Human Rights

    Directory of Open Access Journals (Sweden)

    Pia Oberoi

    2013-07-01

    Full Text Available This article considers contemporary border management regimes from a human rights perspective. It demonstrates how a preoccupation with border controls and enforcement has led to serious concerns for the safety and protection of migrants. As border zones have expanded, border crossing has become a more stigmatized and dangerous activity, and even as globalization has given rise to easier and faster international travel, for some, such movement has been outlawed and stigmatized. Measures to strengthen and “secure” borders have paradoxically made migrants, particularly irregular and vulnerable migrants, more at risk of violence and exploitation by non-State and State actors. Migration governance regimes at international borders are thus increasingly located within security and enforcement frameworks that pay little attention to the principles and standards of international human rights law. The paper argues that a human rights-based approach to such regimes is urgently needed, in order to address a growing human rights crisis at international borders.

    The aim of this study was to determine the time course for adaptation of the reticulo-rumen, omasum, abomasum, and small intestine in response to an abrupt increase in the proportion of grain in the diet. Adaptive responses include tissue and digesta mass, small intestinal length, and brush border enzyme activity in the duodenum, proximal jejunum, and ileum. Twenty-five Holstein steers (213 ± 23 kg; 5 to 7 mo of age) were blocked by body weight, and within block were randomly assigned to 1 of 5 treatments: the control diet (CTRL; 92% chopped grass hay and 8% mineral and vitamin supplement on a dry matter basis) or a moderate grain diet (MGD; 50% chopped grass hay, 42% rolled barley grain, and 8% mineral and vitamin supplement) that was fed for 3 (MGD3), 7 (MGD7), 14 (MGD14), or 21 d (MGD21). Dry matter intake was limited to 2.25% of body weight to ensure that changes in dry matter intake did not confound the results. On the last day of the dietary exposure, steers were slaughtered 2 h after feeding. Reticulo-rumen tissue mass and ruminal epithelium mass in the ventral sac of the rumen were not affected by the MGD. Wet reticulo-ruminal digesta mass decreased from CTRL to MGD7 and then increased, but reticulo-ruminal digesta dry matter mass did not differ between treatments. Omasal mass, omasal tissue mass, and omasum digesta mass decreased linearly with the number of days fed MGD, but abomasal tissue mass tended to increase linearly. Duodenal tissue mass tended to increase linearly, and ileal length increased linearly with the number of days fed MGD. Lactase activity in the proximal jejunum increased linearly and maltase activity in duodenum tended to increase linearly with days fed MGD. Aminopeptidase N activity in the proximal jejunum increased cubically with days fed MGD, and dipeptidylpeptidase IV activity in ileum tended to decrease from CTRL to MGD14 and then tended to increase. Adaptation to a diet with a greater proportion of concentrate involves changes in

    Pulses to steer the time evolution of quantum systems can be designed with optimal control theory. In most cases it is the coherent processes that can be controlled and one optimizes the time evolution towards a target unitary process, sometimes also in the presence of non-controllable incoherent processes. Here we show how to extend the GRAPE algorithm in the case where the incoherent processes are controllable and the target time evolution is a non-unitary quantum channel. We perform a gradient search on a fidelity measure based on Choi matrices. We illustrate our algorithm by optimizing a measurement pulse for superconducting phase qubits. We show how this technique can lead to large measurement contrast close to 99%. We also show, within the validity of our model, that this algorithm can produce short 1.4 ns pulses with 98.2% contrast.

  7. Border poetics

    Directory of Open Access Journals (Sweden)

    Liv Lundberg

    2014-07-01

    Full Text Available The language of poetry is a language of inquiry, not the language of a genre. Poetry has the capacity of entering those zones known as borderlands, where you meet strange things and foreign people. In this poetic world view, the border is not an edge along the fringe of lands, societies and experiences, but rather their very middle – and their in-between. The structures of language are social structures in which meanings and intentions are already in place, always fighting for power and dominance, with rhetorical figures and more violent weapons.

    Full text: Preventing the illicit nuclear and radioactive materials transportation across the state borders has recently taken on a special significance due to ongoing threat of utilizing these materials for terrorist purposes. Currently more and more countries are gaining better understanding of the importance of creating the national security system. It is obvious that the threat of nuclear terrorism is not the only reason to stimulate these efforts and actions. Another reason is existence of 'orphan' sources which number in the world is approaching to 200 000 including the ones with a very high activity. Uncontrolled presence of such sources and materials in the human environment can be hazardous to human health and it may cause significant economical losses. Radiation control at the borders of the countries in this case is the first line of defense on the route of illicit nuclear and radioactive material movement and therefore vitally important for country/state radiation protection. Radiation control at the borders of the states requires three steps: 1) primary control or detecting the presence of radioactive sources on a controlled object; 2) additional radiation control or locating the exact place of the radioactive source on the person, within the vehicle or inside the container; 3) identification of the nature of the radioactive source. To accomplish the first and the main step of radiation control process the high sensitive gamma-neutron portal monitors operating in automatic mode are utilized. They are used to alert authorities to the appearance of any radioactive source in the controlled area. These monitors are developed and manufactured in some countries and currently deployed at the borders of the countries and also in areas where the radioactive sources may appear. However, the experience of deploying the portal monitors in various countries (Poland, Russia, Belarus) (1-3) has proved that the installation even the best of the best monitors is just

    Background Parameters of myocardial deformation have been suggested to be superior to conventional measures of ventricular function in patients with tetralogy of Fallot (ToF), but have required non-routine, tagged cardiovascular magnetic resonance (CMR) techniques. We assessed biventricular myocardial function using CMR cine-based feature tracking (FT) and compared it to speckle tracking echocardiography (STE) and to simple endocardial border delineation (EBD). In addition, the relation between parameters of myocardial deformation and clinical parameters was assessed. Methods Overall, 28 consecutive adult patients with repaired ToF (age 40.4 ± 13.3 years) underwent standard steady-state-free precession sequence CMR, echocardiography, and cardiopulmonary exercise testing. In addition, 25 healthy subjects served as controls. Myocardial deformation was assessed by CMR based FT (TomTec Diogenes software), CMR based EBD (using custom written software) and STE (TomTec Cardiac Performance Analysis software). Results Feature tracking was feasible in all subjects. A close agreement was found between measures of global left (LV) and right ventricular (RV) global strain. Interobserver agreement for FT and STE was similar for longitudinal LV global strain, but FT showed better inter-observer reproducibility than STE for circumferential or radial LV and longitudinal RV global strain. Reproducibility of regional strain on FT was, however, poor. The relative systolic length change of the endocardial border measured by EBD yielded similar results to FT global strain. Clinically, biventricular longitudinal strain on FT was reduced compared to controls (P < 0.0001) and was related to the number of previous cardiac operations. In addition, FT derived RV strain was related to exercise capacity and VE/VCO2-slope. Conclusions Although neither the inter-study reproducibility nor accuracy of FT software were investigated, and its inter-observer reproducibility for regional

    Better understanding of three-dimensional (3D) morphology of the pelvis at the area of inferior border of the arcuate line is very important, which could guide the surgeons to treat pelvic and acetabular fractures more efficiently. The objective of this study is to provide references for screw placement and design of anatomical internal fixators for the fixation route along the pelvic inferior border of the arcuate line. Seventy five cases of computed tomography (CT) scan data were collected using Medical Image Database in Shanghai General Hospital between December 2009 and November 2010. 44 males and 31 females, aging from 21 to 91 years (average: 57.8 years) were enrolled. Using MIMICS 13.0, these data were used for three dimensional (3D) reconstructions of pelvic model. A curve from the pubic tubercle, along the inferior border of the arcuate line, to the sacroiliac joint was depicted and then divided into 11 equal parts. The measurements of whole length of the curve, the radius of the curvature and the thickness of bone at each decile point were performed, respectively. The thinnest bone thickness at acetabular area was 17.24 ± 2.90 mm and 9.94 ± 2.69 mm for male and female, respectively. The radius of curvature at the decile points 1, 8 and 10 were smaller compared with the surrounding points. Using a screw shorter than 10 mm perpendicular to the bone surface along the inferior border of the arcuate line can avoid intra-articular screw penetration. There should be more recontouring of the plate at the areas of pubic tubercle and posterior edge of the acetabulum when placing a fixator along this fixation route. This study provides solid guidance for pelvic and acetabular surgeries as well as designing of anatomical fixators along inferior border fixation route at this area.

    This chapter highlights the legal problems raised by the concept of a border installation. Using the Cattenom nuclear power plant as an example, the author describes the different stages of the legal conflict raised by construction of the plant and analyses the relationship between French administrative law and some provisions of the Euratom Treaty. Based on the Treaty, the Community institutions have adopted directives to strengthen inter-State co-operation and consultation between neighbouring countries. He observes that these principles of co-operation, consultation and vigilance already exist in public international law; however, international case law has not yet made it possible to establish the strict liability of the constructing state in case of a nuclear accident (NEA) [fr

    Full Text Available El número de casos de tuberculosis registrados en los Estados Unidos de América (EE.UU. disminuyó entre 1990 y 1999, pero la proporción de casos ocurridos en personas nacidas en el extranjero aumentó de 24 a 43%. Gran parte de estas personas habían venido de México y de Centroamérica y entre ellas había individuos y familias que habían entrado en los EE.UU. legalmente, así como otras sin permiso ni documentación. El problema de la tuberculosis en los EE.UU. está concentrado en gran medida en los cuatro estados fronterizos con México: Arizona, California, Nuevo México y Tejas. Como reacción a estas tendencias, en junio de 1999 los Centros para el Control y la Prevención de Enfermedades (CDC de los EE.UU. organizaron una reunión de los funcionarios responsables del control de la tuberculosis en estos cuatro estados, con el fin de desarrollar una estrategia nacional coordinada. Este grupo de trabajo especial ha elaborado recientemente un documento con información sobre los antecedentes del problema y propuestas para acciones futuras por parte de los organismos gubernamentales de los EE.UU. y de los programas estatales y locales. El informe se centra en cuatro áreas principales: 1 necesidades de la vigilancia; 2 tratamiento de los casos y su cumplimiento; 3 indicadores de rendimiento y evaluación del programa, y 4 necesidades de investigación. El grupo especial de trabajo identificó los problemas clave, los objetivos y los recursos necesarios en cada una de estas áreas para potenciar los esfuerzos para prevenir y controlar la tuberculosis a lo largo de la frontera.

    "This article examines how data on INS [Immigration and Naturalization Service] border apprehensions are related to the flow of undocumented migrants crossing the southern U.S. border. Its centerpiece is a demographic model of the process of unauthorized migration across the Mexico-U.S. frontier. This model is both a conceptual framework that allows us to see theoretical linkages between apprehensions and illegal migrant flows, and a methodological device that yields estimates of the gross number of undocumented migrants. One implication of the model is that, for the first time, the relation between apprehensions and illegal flows can be examined empirically. We show that the ratio in each period between apprehensions and the undocumented flow is simply the odds of being located and arrested on any given attempt to enter the United States clandestinely." excerpt

En la época actual, transformaciones recientes y procesos de integración económica plantean serios desafíos a los mecanismos tradicionales para el control y la regulación de la dinámica fronteriza. Pero más importante, la frontera México-Guatemala ha confirmado su papel histórico como un ámbito de intensa movilidad poblacional, la cual requiere una regulación apropiada que no atente contra los derechos humanos o -en su caso- laborales de los migrantes, ni tampoco contra el bienestar y el desarrollo sustentable de las regiones de origen y de destino de estas personas.

  16. BOOK REVIEW Quantum Measurement and Control Quantum Measurement and Control

    Science.gov (United States)

    Kiefer, Claus

    2010-12-01

    In the last two decades there has been an enormous progress in the experimental investigation of single quantum systems. This progress covers fields such as quantum optics, quantum computation, quantum cryptography, and quantum metrology, which are sometimes summarized as `quantum technologies'. A key issue there is entanglement, which can be considered as the characteristic feature of quantum theory. As disparate as these various fields maybe, they all have to deal with a quantum mechanical treatment of the measurement process and, in particular, the control process. Quantum control is, according to the authors, `control for which the design requires knowledge of quantum mechanics'. Quantum control situations in which measurements occur at important steps are called feedback (or feedforward) control of quantum systems and play a central role here. This book presents a comprehensive and accessible treatment of the theoretical tools that are needed to cope with these situations. It also provides the reader with the necessary background information about the experimental developments. The authors are both experts in this field to which they have made significant contributions. After an introduction to quantum measurement theory and a chapter on quantum parameter estimation, the central topic of open quantum systems is treated at some length. This chapter includes a derivation of master equations, the discussion of the Lindblad form, and decoherence - the irreversible emergence of classical properties through interaction with the environment. A separate chapter is devoted to the description of open systems by the method of quantum trajectories. Two chapters then deal with the central topic of quantum feedback control, while the last chapter gives a concise introduction to one of the central applications - quantum information. All sections contain a bunch of exercises which serve as a useful tool in learning the material. Especially helpful are also various separate

    Many studies have found that international borders represent large barriers to trade. But how do international borders compare to domestic border barriers? We investigate international and domestic border barriers in a unified framework. We consider a data set of exports from individual US states to foreign countries and combine it with trade flows between and within US states. After controlling for distance and country size, we estimate that relative to state-to-state trade, crossing an indi...

    For the most rapidly growing economic entity in the world, China, a new logistics operation called the indirect cross-border supply chain model has recently emerged. The primary idea of this model is to reduce logistics costs by storing goods at a bonded warehouse with low storage cost in certain Chinese regions, such as the Pearl River Delta (PRD). This research proposes a performance measurement system (PMS) framework to assess the direct and indirect cross-border supply chain models. The PMS covers four categories including cost, time, quality and flexibility in the assessment of the performance of direct and indirect models. Furthermore, a survey was conducted to investigate the logistics performance of third party logistics (3PLs) at the PRD regions, including Guangzhou, Shenzhen and Hong Kong. The significance of the proposed PMS framework allows 3PLs accurately pinpoint the weakness and strengths of it current operations policy at four major performance measurement categories. Hence, this helps 3PLs further enhance the competitiveness and operations efficiency through better resources allocation at the area of warehousing and transportation.

    Full Text Available Leadership measurement, feedback, and development have grown in importance for the field of management. The Mexico–US Border defined as the area of land within 100 km (62.5 miles north and south of the international boundary, shares common challenges, and requires the development of multicultural change agents who conduct binational actions toward the improvement of public health and quality of life of the population in the region. Leaders across Borders (LaB was established in 2010 as an advanced certified binational leadership development program aimed at building the capacity of public health, health care, and other community sector leaders working to improve the health of the communities in the Mexico–US Border region. Leadership as a social interaction process requires leader skills development to achieve goals promoting unity and reducing polarization to optimize interactions between all resources, thus improving teamwork. Therefore, measurement and feedback model of general values and beliefs that guide effective behavior, not only individual personality assessments need to drive a proactive learning and action plan development to improve interactions in a team, thus optimizing leadership. Starting 2014, we administered a new model named Systemic Multiple Level Observation of Groups (SYMLOG to measure the values and beliefs that guide the behavior of learners and team facilitators. We also evaluated the effectiveness of each team of the program and established benchmarks and action plans to optimize interactions and communication between all the learners during the 8-month program. This leads to a stronger systemic network upon graduation from the program. The SYMLOG approach measured initial and improved situations of individual leadership and team performance effectiveness because of the LaB Program training and skills development sessions. The SYMLOG also provided positive feedback to each participant, which had a direct impact

    The prevalence of diabetes is alarmingly high among Mexican American adults residing near the U.S.-Mexico border. Depression is also common among Mexican Americans with diabetes, and may have a negative influence on diabetes management. Thus, the purpose of the current study was to evaluate the associations of depression and anxiety with the behavioral management of diabetes and glycemic control among Mexican American adults living near the border. The characteristics of Mexican Americans with diabetes living in Brownsville, TX (N = 492) were compared by depression/anxiety status. Linear regression models were conducted to evaluate the associations of depression and anxiety with BMI, waist circumference, physical activity, fasting glucose, and glycated hemoglobin (HbA1c). Participants with clinically significant depression and/or anxiety were of greater age, predominantly female, less educated, more likely to have been diagnosed with diabetes, and more likely to be taking diabetes medications than those without depression or anxiety. In addition, anxious participants were more likely than those without anxiety to have been born in Mexico and to prefer study assessments in Spanish rather than English. Greater depression and anxiety were associated with poorer behavioral management of diabetes (i.e., greater BMI and waist circumference; engaging in less physical activity) and poorer glycemic control (i.e., higher fasting glucose, HbA1c). Overall, depression and anxiety appear to be linked with poorer behavioral management of diabetes and glycemic control. Findings highlight the need for comprehensive interventions along the border which target depression and anxiety in conjunction with diabetes management.

    Evaluate the association between driving distance to the US-Mexico border and rural-urban differences in the use of health services in Mexico by US border residents from Texas. Data for this study come from the Cross-Border Utilization of Health Care Survey, a population-based telephone survey conducted in the Texas border region in spring 2008. Driving distances to the border were estimated from the nearest border crossing station using Google Maps. Outcome measures included medication purchases, physician visits, dentist visits, and inpatient care in Mexico during the 12 months prior to the survey. A series of adjusted logit models were estimated after controlling for relevant confounding factors. The average driving distance to the nearest border crossing station among rural respondents was 4 times that of urban respondents (42.0 miles vs 10.3 miles [P Rural respondents were more likely to be dissatisfied than urban respondents with the health care provided on the US side of the border, yet they were less likely to use health services in Mexico. Driving distance to the border largely explained the observed rural-urban differences in medication purchases from Mexico. In the case of inpatient care, however, rural respondents reported a higher utilization rate than urban respondents and this rural-urban difference became more pronounced after adjusting for the effect of driving distance to the border. Dissatisfaction with US health care services in rural communities in the US-Mexico border region seems to be compounded by the lack of access to health care services in Mexico due to travel distance constraints. No claim to original US government works.

    The series reports how general people, who are not radiological experts, have faced and understood the problems and tasks of radiation by the Fukushima Nuclear Power Plant Accident (Mar. 11, 2011). The section 4 is reported by a mother having 3 school children living in Kosugo, Shiroishi City, Miyagi Prefecture, localizing at the border to Fukushima Prefecture, 65 km distant from the Plant. Just after the Accident, the author was first eased by the government view, no immediate radiation effects by the Accident, and then became anxious, particularly about children, by the similar Miyagi prefectural view despite American recommendation for evacuation to the area 80 km far from the Plant and Kosugo's enrollment in the contaminated region. Major trend in the town was against the interest in radiation problems as the region was not in Fukushima and there were fears about the reputational risk. Under these circumstances, dosimeters and surveymeters, which had been lent by neither Miyagi nor Shiroishi, were lent thanks to the favor of Tohoku University, and have been used to measure the radiation doses in the school zone. Decontamination of Kosugo primary school garden of which dose had been 0.95 mc-Sv/hr in April, 2011, was conducted as lately as in July, 2012. The exposure dose to pupils was conceivably higher than that in the neighboring Fukushima school whose decontamination had been conducted in July, 2011. Is this really 'No problem'? Differing from Fukushima where the prefectural health project started already, Kosugo children have come to receive the pay thyroid echo examination since January, 2014, and 64% of pupils wish to have the diagnosis. The author prays for science to let children be safe for their bright future beyond the border. (T.T.)

    A PDP 11/35 computer system is used in evaluating analytical chemistry measurements quality control data at the Barnwell Nuclear Fuel Plant. This computerized measurement quality control system has several features which are not available in manual systems, such as real-time measurement control, computer calculated bias corrections and standard deviation estimates, surveillance applications, evaluaton of measurement system variables, records storage, immediate analyst recertificaton, and the elimination of routine analysis of known bench standards. The effectiveness of the Barnwell computer system has been demonstrated in gathering and assimilating the measurements of over 1100 quality control samples obtained during a recent plant demonstration run. These data were used to determine equaitons for predicting measurement reliability estimates (bias and precision); to evaluate the measurement system; and to provide direction for modification of chemistry methods. The analytical chemistry measurement quality control activities represented 10% of the total analytical chemistry effort

In addition, focus group discussions were carried out in 12 villages involving 248 people using a standardized list of questions. The outcome suggested that there was a very low level of awareness of biosecurity practices amongst smallholder farmers. We conclude that adoption of specific biosecurity practices by smallholder farmers is feasible but requires institutional support. There is a clear requirement for government authorities to sensitize farmers using approaches that allow active participation of farmers in the design, planning and implementation of biosecurity practices to enable enhanced adoption.

    Engel and Rogers (1996) find that crossing the US-Canada border can considerably raise relative price volatility and that exchange rate fluctuations explain about one-third of the volatility increase. In reevaluating the border effect, this study shows that cross-country heterogeneity in price volatility can lead to significant bias in measuring the border effect unless proper adjustment is made to correct it. The analysis explores the implication of symmetric sampling for border effect estim...

    A set of measurment control data analyses was selected for use by analysts responsible for maintaining measurement quality of nuclear materials accounting instrumentation. The analyses consist of control charts for bias and precision and statistical tests used as analytic supplements to the control charts. They provide the desired detection sensitivity and yet can be interpreted locally, quickly, and easily. The control charts provide for visual inspection of data and enable an alert reviewer to spot problems possibly before statistical tests detect them. The statistical tests are useful for automating the detection of departures from the controlled state or from the underlying assumptions (such as normality). 8 refs., 3 figs., 5 tabs

    Many studies have found that international borders represent large barriers to trade. But how do international borders compare to domestic border barriers? We investigate international and domestic border barriers in a unified framework. We consider a unique data set of exports from individual U.S. states to foreign countries and combine it with trade flows within and between U.S. states. After controlling for distance and country size, we find that relative to state-to-state trade, crossing ...

    Online self-presentation assumes that individuals intentionally control how others perceive them based on their online behaviors. Existing tools are limited in their ability to measure this notion of perception control and there is little understanding around factors which may affect the desire for perception control. This article reports on the development of a perception control scale and comparisons of perception control across age and between genders. A total of 222 participants completed an online survey with items measuring perception control and participant demographics. A principal component analysis revealed a one-factor, 12-item scale explaining 41.14% of the variance. Perception control was found to increase with age and did not differ between genders. Results are consistent with existing impression management research suggesting that while participants of both genders desire to control how others perceive them, as a person's sense of self stabilizes over time, they are less motivated to change their behaviors to control others' impressions of them.

    2018-01-01

    In the Colorado River downstream of Glen Canyon Dam in the Grand Canyon, USA, controlled floods are used to resupply sediment to, and rebuild, river sandbars that have eroded severely over the past five decades owing to dam-induced changes in river flow and sediment supply. In this study, we examine whether controlled floods, can in turn resupply aeolian sediment to some of the large source-bordering aeolian dunefields (SBDs) along the margins of the river. Using a legacy of high-resolution lidar remote-sensing and meteorological data, we characterize the response of four SBDs (a subset of 117 SBDs and other aeolian-sand-dominated areas in the canyon) during four sediment-laden controlled floods of the Colorado River in 2012, 2013, 2014, and 2016. We find that aeolian sediment resupply unambiguously occurred in 8 of the 16 instances of controlled flooding adjacent to SBDs. Resupply attributed to individual floods varied substantially among sites, and occurred with four, three, one, and zero floods at the four sites, respectively. We infer that the relative success of controlled floods as a regulated-river management tool for resupplying sediment to SBDs is analogous to the frequency of resupply observed for fluvial sandbars in this setting, in that sediment resupply was estimated to have occurred for roughly half of the instances of recent controlled flooding at sandbars monitored separately from this study. We find the methods developed in this, and a companion study, are effective tools to quantify geomorphic changes in sediment storage, along linked fluvial and aeolian pathways of sedimentary systems.

    Full Text Available Past studies of postural control during standing have employed wide range of procedures including the outcome measures use to quantify postural control, the duration of the sample collected, sampling frequency and methods for data processing. Due to these differences there remains little, if any, common grounds for comparisons between studies to establish a concrete understanding of the features and bouns which characterize normal healthy postural control. This article deals with terms such as reliability and repeatability of stabilometric measurements, stabilometric data quantification and analysis. To clear up those terms is suggested, by the author of this paper, very important. The stabilometric measurements remain, nevertheless, different when dealing with aging adults. Though, we notes some alterations of the aging systems, this article is not entirely dedicated to the seniors population. Measurements of COP and technical notes remain the main axis of present paper.

    1987-04-01

    This report summarizes the design of the measurement control (MC) program for the New Special Recovery facility. The MC program is divided into two levels. Level 1 MC checks are performed at the individual instrument computer and will always be functional even when the instrument-control computer is down. The level 1 MCs are divided into statistical checks for both bias and precision, and diagnostic checks. All the instruments are connected on line to an instrument-control computer to which the measurement results can be communicated. Level 2 MC analyses are performed at this computer. The analyses consist of control charts for bias and precision and statistical tests used as analytic supplements to the control charts. They provide the desired detection sensitivity and yet can be interpreted quickly and easily. Recommendations are also made in terms of the frequency of the tests, the standard used, and other operational aspects of the MC program. 16 refs., 11 figs., 10 tabs

    1999-03-01

    This document is an analysis of options for unilateral and cooperative action to improve the security of Jordan's borders. Sections describe the current political, economic, and social interactions along Jordan's borders. Next, the document discusses border security strategy for cooperation among neighboring countries and the adoption of confidence-building measures. A practical cooperative monitoring system would consist of hardware for early warning, command and control, communications, and transportation. Technical solutions can expand opportunities for the detection and identification of intruders. Sensors (such as seismic, break-wire, pressure-sensing, etc.) can warn border security forces of intrusion and contribute to the identification of the intrusion and help formulate the response. This document describes conceptual options for cooperation, offering three scenarios that relate to three hypothetical levels (low, medium, and high) of cooperation. Potential cooperative efforts under a low cooperation scenario could include information exchanges on military equipment and schedules to prevent misunderstandings and the establishment of protocols for handling emergency situations or unusual circumstances. Measures under a medium cooperation scenario could include establishing joint monitoring groups for better communications, with hot lines and scheduled meetings. The high cooperation scenario describes coordinated responses, joint border patrols, and sharing border intrusion information. Finally, the document lists recommendations for organizational, technical, and operational initiatives that could be applicable to the current situation.

    Full Text Available Polish and Russian cross-border cooperation is governed by lawful agreements. The enlargement of the Schengen Area had a significant impact on Kaliningrad Oblast relations and cross-border cooperation with its neighbours. The introduction of visas between Poland and Russia hindered and restricted local border trade which had for years been the only measure mitigating social and economic problems of the cross-border regions. Nevertheless, border traffic between Poland and Kaliningrad grew steadily, to exceed four million in 2012.

    Norman, Elisabeth; Price, Mark C; Jones, Emma

    2011-12-01

    In response to concerns with existing procedures for measuring strategic control over implicit knowledge in artificial grammar learning (AGL), we introduce a more stringent measurement procedure. After two separate training blocks which each consisted of letter strings derived from a different grammar, participants either judged the grammaticality of novel letter strings with respect to only one of these two grammars (pure-block condition), or had the target grammar varying randomly from trial to trial (novel mixed-block condition) which required a higher degree of conscious flexible control. Random variation in the colour and font of letters was introduced to disguise the nature of the rule and reduce explicit learning. Strategic control was observed both in the pure-block and mixed-block conditions, and even among participants who did not realise the rule was based on letter identity. This indicated detailed strategic control in the absence of explicit learning. Copyright © 2011 Elsevier Inc. All rights reserved.

  16. Ras-dva1 small GTPase regulates telencephalon development in Xenopus laevis embryos by controlling Fgf8 and Agr signaling at the anterior border of the neural plate

    Directory of Open Access Journals (Sweden)

    Maria B. Tereshina

    2014-07-01

    Full Text Available We previously found that the small GTPase Ras-dva1 is essential for the telencephalic development in Xenopus laevis because Ras-dva1 controls the Fgf8-mediated induction of FoxG1 expression, a key telencephalic regulator. In this report, we show, however, that Ras-dva1 and FoxG1 are expressed in different groups of cells; whereas Ras-dva1 is expressed in the outer layer of the anterior neural fold, FoxG1 and Fgf8 are activated in the inner layer from which the telencephalon is derived. We resolve this paradox by demonstrating that Ras-dva1 is involved in the transduction of Fgf8 signal received by cells in the outer layer, which in turn send a feedback signal that stimulates FoxG1 expression in the inner layer. We show that this feedback signal is transmitted by secreted Agr proteins, the expression of which is activated in the outer layer by mediation of Ras-dva1 and the homeodomain transcription factor Otx2. In turn, Agrs are essential for maintaining Fgf8 and FoxG1 expression in cells at the anterior neural plate border. Our finding reveals a novel feedback loop mechanism based on the exchange of Fgf8 and Agr signaling between neural and non-neural compartments at the anterior margin of the neural plate and demonstrates a key role of Ras-dva1 in this mechanism.

    Full Text Available System-on-a-chip (SoC bus systems are typically confined on-chip and rely on higher level components to communicate with the outside world. The idea behind the EtherBone (EB protocol is to extend the reach of the SoC bus to remote field-programmable gate arrays or processors. The EtherBone core implementation connects a Wishbone (WB Ver. 4 Bus via a Gigabit Ethernet based network link to remote peripheral devices. EB acts as a transparent interconnect module towards attached WB Bus devices. EB was developed in the scope of the WhiteRabbit Timing Project at CERN and GSI/FAIR. WhiteRabbit will make use of EB as a means to issue commands to its timing nodes and control connected accelerator hardware.

    Over the past few ears, the preparation of ITER-relevant plasma scenarios has been the main focus experimental activity on tokamaks. The development of integrated, simultaneous, real-time controls of plasma shape, current, pressure, temperature, radiation, neutron profiles, and also impurities, ELMs (edge localized modes) and MHD are now seen to be essential for further development of quasi-steady state conditions with feedback, or the stabilisation of transient phenomena with event-driven actions. For this thrust, the EFDA JET Real Time Project has developed a set of real-time plasma measurements, experiment control, and communication facilities. The Plasma Diagnostics used for real-time experiments are Far Infra Red interferometry, polarimetry, visible, UV and X-ray spectroscopy, LIDAR, bolometry, neutron and magnetics. Further analysis systems produce integrated results such as temperature profiles on geometry derived from MHD equilibrium solutions. The Actuators include toroidal, poloidal and divertor coils, gas and pellet fuelling, neutral beam injection, radiofrequency (ICRH) waves and microwaves (LH). The Heating/Fuelling Operators can either define a power or gas request waveform or select the real-time instantaneous power/gas request from the Real Time Experiment Central Control (RTCC) system. The Real Time Experiment Control system provides both a high-level, control-programming environment and interlocks with the actuators. A MATLAB facility is being developed for the development of more complex controllers. The plasma measurement, controller and plant control systems communicate in ATM network. The EFDA Real Time project is essential groundwork for future reactors such as ITER. It involves many staff from several institutions. The facility is now frequently used in experiments. (authors)

    A fluidic Turbine Inlet Gas Temperature (TIGIT) Measurement and Control System was developed for use on a Pratt and Whitney Aircraft J58 engine. Based on engine operating requirements, criteria for high temperature materials selection, system design, and system performance were established. To minimize development and operational risk, the TIGT control system was designed to interface with an existing Exhaust Gas Temperature (EGT) Trim System and thereby modulate steady-state fuel flow to maintain a desired TIGT level. Extensive component and system testing was conducted including heated (2300F) vibration tests for the fluidic sensor and gas sampling probe, temperature and vibration tests on the system electronics, burner rig testing of the TIGT measurement system, and in excess of 100 hours of system testing on a J58 engine.

    Tengchong County experienced a decreasing malaria prevalence period in 2005-2014 but the factors contributing to the trend are unclear. Herein, the malaria epidemiological data in years of 2005-2014 were collected and analysed, in order to provide evidence for subsequent effective strategic planning of malaria elimination that may be referenced by other counties with the similar elimination programmes along the China-Myanmar border. A retrospective study was conducted to explore malaria-endemic characteristics in years 2005-2014 in Tengchong County. All individual cases from a web-based reporting system were reviewed and analysed. Local infections and imported cases were obtained from an annual reporting system. In total, 8321 confirmed malaria cases were recorded in this period, and 91.5% of them were reported during 2005-2010. Plasmodium vivax was the major species (n = 5867, 70.5%). Most cases (92.9%) were found in males, mainly in the age group 30-34 years. Only five deaths resulting from Plasmodium falciparum were reported, of which three occurred in 2005. The cases were mainly reported in the townships of Wuhe (18.5%), Mangbang (12.8%) and Gudong (9.3%). In addition, 147 local malaria (1.8%) and 8174 imported malaria (98.2%) were observed during 2005-2014. However, the proportion of imported malaria was more than 95% all the time and no local transmission has been observed since 2013. Moreover, Myanmar was the main imported source, with 716 cases (94.6%, 716/757) from Myanmar in 2011-2014. Tengchong County has made achievements in controlling malaria, with incidence at historically its lowest level. However, imported malaria has increased and poses a great threat to malaria elimination. To achieve the elimination goal and prevent the re-introduction of malaria, surveillance systems need to be well planned and managed to ensure timely case detection and prompt response targeted to the mobile and migrate population at elimination stage.

  14. Partition of distinct chromosomal regions: negotiable border and fixed border.

    Science.gov (United States)

    Kimura, Akatsuki; Horikoshi, Masami

    2004-06-01

    Chromosomes are partitioned into distinct functional regions. For example, heterochromatin regions consist of condensed chromatin and contain few transcriptionally active genes, whereas euchromatin regions are less condensed and majority of active genes reside in the euchromatin regions. Because distinct regions reside in each chromosome, borders are accordingly established between these regions. A prevailing view of the borders is that they are 'walls' that actively inhibit communication between distinct regions on chromosomes. Although little is known about the molecular bases of these walls, specific DNA elements are considered to recruit these walls to define the positions of the borders. We call the borders established with this mechanism as 'fixed borders'. Past studies have identified various insulators (boundary DNA elements) that have been suggested to recruit fixed borders to them. Another mechanism, which we introduce and focus on in this review, does not require walls recruited by specific DNA elements at the chromosomal borders. Instead, the borders are defined by a balance of opposing enzymatic activities located at the opposite sides of the resultant borders. We name these borders 'negotiable borders'. Here we review some of the recent progress in the field that offer valuable insight into mechanisms of establishing structural and functional borders on chromosomes.

    2017-04-01

    The Bay of Biscay-Pyrenean geological system is an inverted hyperextended rift that illustrates in its deep structure the transition between an oceanic underthrusting in the west to a continent-continent collision in the east. We developed a structural analysis of the south-western reactivated rift system, which represents at present-day the western branch of the Cantabrian-Pyrenean collisional chain, including the Cantabrian Mountains onshore and the central and western segments of the North Iberian margin in the southern Bay of Biscay. This passive margin was structured during polyphase Triassic to Lower Cretaceous rifting events and subsequently inverted in the Cenozoic during the Alpine orogeny, when the Cantabrian-Pyrenean realm formed in the Iberian-European plate boundary. The reactivated rift system shows a significant structural variability resulting from the strong segmentation and strain partitioning during the subsequent tectonic events. Thus, it is a natural laboratory to study the constraints imposed by tectonic inheritance in the successive stages of an almost complete orogenic cycle. From the interpretation of offshore geological and geophysical data and the integration of onshore wide-angle results, where Mesozoic fossil remnants are very scarce, we analyzed the crustal structure of the reactivated rift system and mapped the now inverted rift domains. Our results show that the inherited rift architecture controlled the subsequent compressional reactivation of the hyperextended rift system. Of particular interest are the structural variations observed in proximal areas. Offshore, the proximal domain includes classical shallow grabens and half-grabens with low degrees of extension developed during an early Permo-Triassic rift event governed by stretching processes. Its NW-SE distal limit runs parallel to the Cantabrian Fault. Following this trend, a major structure, called Ventaniella fault, has been traditionally mapped onshore, interpreted as a

    Previous studies in the border-effect literature surprisingly found that domestic border effects are larger than international border effects (e.g., in the United States or Brazil). One interpretation of this result is that these estimates include the effects of producer agglomeration. Therefore, in this study, we estimate those border effects exclusively for transactions for final consumption, in which such agglomeration forces will be weak, in China and Japan. As a result, we found larger i...

    Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is determined by multiple factors affecting it. In U.S. portions of the bi-national Santa Cruz Watershed (SCW), situated at the Arizona-Sonora International border, natural amenities like the riparian corridor and green space have been documented as positive amenities that boost local real estate.

    2015-11-17

    Between September 2014 and February 2015, the number of Ebola virus disease (EVD) cases reported in Sierra Leone declined in many districts. During this period, a major international response was put in place, with thousands of treatment beds introduced alongside other infection control measures. However, assessing the impact of the response is challenging, as several factors could have influenced the decline in infections, including behavior changes and other community interventions. We developed a mathematical model of EVD transmission, and measured how transmission changed over time in the 12 districts of Sierra Leone with sustained transmission between June 2014 and February 2015. We used the model to estimate how many cases were averted as a result of the introduction of additional treatment beds in each area. Examining epidemic dynamics at the district level, we estimated that 56,600 (95% credible interval: 48,300-84,500) Ebola cases (both reported and unreported) were averted in Sierra Leone up to February 2, 2015 as a direct result of additional treatment beds being introduced. We also found that if beds had been introduced 1 month earlier, a further 12,500 cases could have been averted. Our results suggest the unprecedented local and international response led to a substantial decline in EVD transmission during 2014-2015. In particular, the introduction of beds had a direct impact on reducing EVD cases in Sierra Leone, although the effect varied considerably between districts.

    The ongoing refugee crisis in Europe has seen many countries rush to construct border security fencing to divert or control the flow of people. This follows a trend of border fence construction across Eurasia during the post-9/11 era. This development has gone largely unnoticed by conservation biologists during an era in which, ironically, transboundary cooperation has emerged as a conservation paradigm. These fences represent a major threat to wildlife because they can cause mortality, obstruct access to seasonally important resources, and reduce effective population size. We summarise the extent of the issue and propose concrete mitigation measures. PMID:27331878

    Using large national databases, we investigated how living in the US-Mexico border region further limited access to healthcare among the non-elderly Hispanic adult population after controlling individual and county-level characteristics. The 2008-2012 individual-level data of non-elderly Hispanic adults from the Behavioral Risk Factor Surveillance System (BRFSS) were merged with county-level data from Area Health Resources File (AHRF). Multivariate logistic analyses were performed to predict insurance status and access to doctors using residency in the US-Mexico border region as the key predictor, adjusting individual and county-level factors. Controlling only individual characteristic, Hispanics living in the US-Mexico border region had significantly lower odds of having health insurance (adjusted odds ratio [AOR] = 0.51; 95% confidence interval [CI], 0.49-0.54) and access to doctors (AOR = 0.69; 95% CI, 0.66-0.72). After including county-level measurements of healthcare system capacity and other local characteristics, the border region continued to be associated with lower likelihood of healthcare access. Hispanic residents in the U.S.-Mexico border had less access to healthcare than their inland counterparts. The findings highlight unique features in this region and support policies and initiatives to improve minority healthcare access, particularly among disadvantaged populations in this region.

    2011-05-01

    As providing a reporting of their greenhouse gas emissions has become mandatory for a large number of French companies, this publication proposes a methodology to perform an assessment or measurement, and a control of such emissions. In its first part, it explains why measurements are required: indication of concerned gases, international consensus to limit temperature rise, definition and chronology of the main steps adopted at the international level and which must be considered in the approach adopted by enterprises in this respect. It outlines the benefits of such a measurement for the enterprise in terms of competitiveness, personnel commitment, new markets and products, image, compliance with the law, operational and financial aspects, and so on. It identifies the various stakeholders to be informed: civil society, financial community, public authorities, clients and consumers, personnel, suppliers. It outlines the diversity and evolution of legal frameworks at the international level as well as at national levels. While evoking many examples of French companies (SNCF, EDF, Seche Environnement, RTE, Michelin, Arcelormittal, AREVA, Air France, EADS-Airbus, AXA, Veolia, and so on), the next part addresses how to measure emissions. It outlines the complexity of the methodological landscape with its various criteria, evokes the various existing standards, outlines the distinction between organisation-based, product-based and project-based approaches, and the distinction between direct and indirect emissions in relationship with the notion of scope. It comments the existence of sector-based methodologies and guidelines, and discusses some difficulties and methodological decisions. The third part proposes some lessons learned from the experience which could lead to a harmonisation of methodologies, proposes a synthesis of reporting approaches, outlines risks and opportunities related to communication

    The author demonstrates the Border Trade Facilitation System (BTFS), an agent-based bilingual e-commerce system built to expedite the regulation, control, and execution of commercial trans-border shipments during the delivery phase. The system was built to serve maquila industries at the US/Mexican border. The BTFS uses foundation technology developed here at Sandia Laboratories' Advanced Information Systems Lab (AISL), including a distributed object substrate, a general-purpose agent development framework, dynamically generated agent-human interaction via the World-Wide Web, and a collaborative agent architecture. This technology is also the substrate for the Multi-Agent Simulation Management System (MASMAS) proposed for demonstration at this conference. The BTFS executes authenticated transactions among agents performing open trading over the Internet. With the BTFS in place, one could conduct secure international transactions from any site with an Internet connection and a web browser. The BTFS is currently being evaluated for commercialization.

  12. Microneedle Manufacture: Assessing Hazards and Control Measures

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Transdermal microneedles have captured the attention of researchers in relation to a variety of applications, and silicone-based moulds required to produce these systems are now widely available and can be readily manufactured on the lab bench. There is however some concern over the potential for accidental needlestick injuries and, as with any sharp hazard, the potential for blood-borne pathogen transmission must be considered. This follows from recent governmental concerns over the use of microneedle systems in dermabrasion. Despite the piercing nature of the microneedle patch sharing many similarities with conventional hypodermic needles, there are notable factors that mitigate the risk of contamination. A range of microneedle systems has been prepared using micromoulding techniques, and their puncture capability assessed. A critical assessment of the potential for accidental puncture and the control measures needed to ensure safe utilisation of the patch systems is presented.

  14. Cardiac output measurement instruments controlled by microprocessors

    International Nuclear Information System (INIS)

    Spector, M.; Barritault, L.; Boeri, C.; Fauchet, M.; Gambini, D.; Vernejoul, P. de

    The nuclear medicine and biophysics laboratory of the Necker-Enfants malades University Hospital Centre has built a microprocessor controlled Cardiac flowmetre. The principle of the cardiac output measurement from a radiocardiogram is well established. After injection of a radioactive indicator upstream from the heart cavities the dilution curve is obtained by the use of a gamma-ray precordial detector. This curve normally displays two peaks due to passage of the indicator into the right and left sides of the heart respectively. The output is then obtained from the stewart Hamilton principle once recirculation is eliminated. The graphic method used for the calculation however is long and tedious. The decreasing fraction of the dilution curve is projected in logarithmic space in order to eliminate recirculation by determining the mean straight line from which the decreasing exponential is obtained. The principle of the use of microprocessors is explained (electronics, logics) [fr

    The cross-border region of the Netherlands (NL) and the two German states of North Rhine Westphalia (NRW) and Lower Saxony (LS) is a large and highly integrated livestock production area. This region increasingly develops towards a single epidemiological area in which disease introduction is a shared veterinary and, consequently, economic risk. The objectives of this study were to examine classical swine fever (CSF) control strategies' veterinary and direct economic impacts for NL, NRW and LS given the current production structure and to analyse CSF's cross-border causes and impacts within the NL-NRW-LS region. The course of the epidemic was simulated by the use of InterSpread Plus, whereas economic analysis was restricted to calculating disease control costs and costs directly resulting from the control measures applied. Three veterinary control strategies were considered: a strategy based on the minimum EU requirements, a vaccination and a depopulation strategy based on NL and GER's contingency plans. Regardless of the veterinary control strategy, simulated outbreak sizes and durations for 2010 were much smaller than those simulated previously, using data from over 10 years ago. For example, worst-case outbreaks (50th percentile) in NL resulted in 30-40 infected farms and lasted for two to four and a half months; associated direct costs and direct consequential costs ranged from €24.7 to 28.6 million and €11.7 to 26.7 million, respectively. Both vaccination and depopulation strategies were efficient in controlling outbreaks, especially large outbreaks, whereas the EU minimum strategy was especially deficient in controlling worst-case outbreaks. Both vaccination and depopulation strategies resulted in low direct costs and direct consequential costs. The probability of cross-border disease spread was relatively low, and cross-border spread resulted in small, short outbreaks in neighbouring countries. Few opportunities for further cross-border harmonization and

    2007-01-01

    High level of environmental and occupational noise remain a problem all over the world. As problems and complaints increased dramatically by the end of the 19th and beginning of the 20th centuries focusing on the problem was intensified. In this thesis occupational noise levels at different places were measured and compared with the international permissible levels using the integrating sound level meter (Quest 2800). The calibration of the instrument was carried out before and after each measurement using the acoustic calibrator (Quest CA-12B calibrator). The method which was followed was measuring the sound pressure level of the different noise sources over a broad frequency band covering the audible frequency range using the (octave band filter, model OB-100), disregrading variation with time. Since the human ear is most sensitive in the 2-5 khz range of frequencies and least sensitive at extremely high and low frequencies the instrument was adjusted on the A weighting net work which varies with frequencies in a very similar way as that of the human ear. From the obtained results, some noise levels which were recorded were within the permissible levels i.e. below 90 dba and some noise levels were higher than the permissible limit as in janzour textile factory (95 dba), The welding workshop (120 dba), Benghazi Macaroni factory (100 dba), and near the air blowers at Zletin cement factory, Benghazi cement factory (97-10-dba) in these cases suggestions were made to minimize the problem. Concerning the noise control, four methods of noise control were tested, these methods were: reducing noise by sound absorbing material at Sirt local broadcasting radio, reducing noise by keeping a distance from the noise source, at the Boilers hall at REWDC, reducing noise by enclosures, at the compressors room at Zletin cement factory, and finally reducing noise by performing regular maintenance at Garabolli photo development centre. The percentage of noise reduction was 21%, 12

  19. Who’s Who at the Border? A rights-based approach to identifying human trafficking at international borders

    Directory of Open Access Journals (Sweden)

    Marika McAdam

    2013-09-01

    Full Text Available International borders are widely touted as bastions in the fight against trafficking in persons. This article acknowledges the important role border officials play in preventing human trafficking, but calls for expectations to be tempered by deference to the conceptual complexity of cross-border trafficking and the migration processes involved. The fact that many trafficked victims begin their journeys as irregular or smuggled migrants highlights the challenge posed to border officials in identifying trafficked persons among the people they encounter. Indicators of trafficking generally relate to the exploitation phase, leaving border officials with little guidance as to how persons vulnerable to trafficking can be accurately identified before any exploitation has occurred. Ultimately, this paper advocates a pragmatic rights-based approach in designating anti-trafficking functions to border officials. A rights-based approach to border control acknowledges the core work of border officials as being to uphold border integrity, while ensuring that their performance of this role does not jeopardise the rights of those they intercept nor result in missed opportunities for specialists to identify trafficked persons and other vulnerable people among them.

  20. Extracellular Trapping of Soil Contaminants by Root Border Cells: New Insights into Plant Defense

    Directory of Open Access Journals (Sweden)

    Martha C. Hawes

    2016-01-01

    Full Text Available Soil and water pollution by metals and other toxic chemicals is difficult to measure and control, and, as such, presents an ongoing global threat to sustainable agriculture and human health. Efforts to remove contaminants by plant-mediated pathways, or “phytoremediation”, though widely studied, have failed to yield consistent, predictable removal of biological and chemical contaminants. Emerging research has revealed that one major limitation to using plants to clean up the environment is that plants are programmed to protect themselves: Like white blood cells in animals, border cells released from plant root tips carry out an extracellular trapping process to neutralize threats and prevent injury to the host. Variability in border cell trapping has been found to be correlated with variation in sensitivity of roots to aluminum, and removal of border cell results in increased Al uptake into the root tip. Studies now have implicated border cells in responses of diverse plant roots to a range of heavy metals, including arsenic, copper, cadmium, lead, mercury, iron, and zinc. A better understanding of border cell extracellular traps and their role in preventing toxin uptake may facilitate efforts to use plants as a nondestructive approach to neutralize environmental threats.

    Social and cultural conditions (including U.S. border and inland influence, role models within the family, and educational background) which affect locus of control and achievement motivation among Mexican entrepreneurs were explored among 64 selected entrepreneurs in two Mexican towns, one on the Mexico-U.S. border, the other located inland. Analyses showed that the border subsample scored higher on External locus of control; however, in both subsamples the father was an important element in the locus of control variable and the entrepreneur status. No statistically significant mean difference was noted for achievement motivation. Practical applications and limitations are discussed.

In a business environment where transaction costs are extremely high, we find that decentralized networks are well adapted to the various uncertainties induced by long-distance trade. We also find that long-distance trade relies both on the trust...... and cooperation shared among local traders, and on the distant ties developed with foreign partners from a different origin, religion or culture. Studying the spatial structure of trade networks, we find that in those markets where trade is recent and where most of the traders are not native of the region...

  4. GEOCHEMICAL CONTROLS ON NUCLEAR MAGNETIC RESONANCE MEASUREMENTS

    2008-01-01

    Proton nuclear magnetic resonance (NMR) is used in the Earth Sciences as a means of obtaining information about the molecular-scale environment of fluids in porous geological materials. Laboratory experiments were conducted to advance our fundamental understanding of the link between the NMR response and the geochemical properties of geological materials. In the first part of this research project, we studied the impact of both the surface-area-to-volume ratio (S/V) of the pore space and the surface relaxivity on the NMR response of fluids in sand-clay mixtures. This study highlighted the way in which these two parameters control our ability to use NMR measurements to detect and quantify fluid saturation in multiphase saturated systems. The second part of the project was designed to explore the way in which the mineralogic form of iron, as opposed to simply the concentration of iron, affects the surface relaxation rate and, more generally, the NMR response of porous materials. We found that the magnitude of the surface relaxation rate was different for the various iron-oxide minerals because of changes in both the surface-area-to-volume ratio of the pore space, and the surface relaxivity. Of particular significance from this study was the finding of an anomalously large surface relaxivity of magnetite compared to that of the other iron minerals. Differences in the NMR response of iron minerals were seen in column experiments during the reaction of ferrihydrite-coated quartz sand with aqueous Fe(II) solutions to form goethite, lepidocrocite and magnetite; indicating the potential use of NMR as a means of monitoring geochemical reactions. The final part of the research project investigated the impact of heterogeneity, at the pore-scale, on the NMR response. This work highlighted the way in which the geochemistry, by controlling the surface relaxivity, has a significant impact on the link between NMR data and the microgeometry of the pore space.

    Non-destructive Assay is applied to machines and components quality tests. These elements would not have a good performance if they were conceived without concern about the mechanical project quality, used materials, manufacture processes and inspection and maintenance methodology. In this work, a measure and control system of non destructive processes was developed, using a radioactive source with a defined energy in function of the material to be analyzed. This system involves: interface of input/output (I/O) (hardware) and graphical interface (software). In the non destructive analysis, it is made the comparison of the signal proceeding from the sensor with a signal preset (set point) or analogical signal of reference (Base Line), which is adjusted in the I/O interface. Analyzed the signal, the system will make the decision: to reject or to accept the analyzed material. The I/O interface is implemented by electronic equipment with a MCS51. The purpose of this interface is to supply conditions to exchange information, using serial RS232, between the sensor and the microcomputer. The graphical interface (software) is written in visual C++ language. (author)

    1 - Description of problem or function: The Safeguards Analytical Laboratory Evaluation (SALE) program is a statistical analysis program written to analyze the data received from laboratories participating in the SALE quality control and evaluation program. The system is aimed at identifying and reducing analytical chemical measurement errors. Samples of well-characterized materials are distributed to laboratory participants at periodic intervals for determination of uranium or plutonium concentration and isotopic distributions. The results of these determinations are statistically evaluated and participants are informed of the accuracy and precision of their results. 2 - Method of solution: Various statistical techniques produce the SALE output. Assuming an unbalanced nested design, an analysis of variance is performed, resulting in a test of significance for time and analyst effects. A trend test is performed. Both within- laboratory and between-laboratory standard deviations are calculated. 3 - Restrictions on the complexity of the problem: Up to 1500 pieces of data for each nuclear material sampled by a maximum of 75 laboratories may be analyzed

    Recent scholarship suggests a significant association between cross-border ties, or ties maintained with family and friends in countries and communities of origin, and the mental health of immigrants and their descendants. To date, this research has been exclusively cross-sectional, precluding conclusions about a causal association between cross-border ties and mental health outcomes. In the present study we undertake a longitudinal analysis of the relationship between cross-border ties and depression measured over a ten-year period for a sample of immigrant and U.S.-born Latinos. Data are from the Sacramento Area Latino Study on Aging (1998-2008), a population-based, prospective study of Latin American-origin adults 60 years and older. We find that cross-border ties reported at baseline were significantly associated with depression in subsequent study waves, even after controlling for the presence of depression at baseline, albeit with substantial differences by gender and nativity. Specifically, communication with family and friends in Latin America and travel to Latin America at baseline were each significantly associated with greater odds of depression for immigrant women, but with lower odds of depression for U.S.-born Latina women over the study period. Travel to Latin America at baseline was significantly associated with lower odds of depression for Latino men across the study. Across all models we control for depressive symptomatology at baseline to account for the reciprocal nature of depressive symptoms and engagement with social ties, including cross-border ties. Our findings suggest that cross-border ties may represent a unique source of both resilience and risk for the long-term mental health of immigrant Latinos and their descendants.

    In Punjab, the principal hydro spheric problems of industrial origin occur in stream and drainage channels where large industries and located. A typical example of this situation is the pollution of Barianwala drain which ultimately discharges into river Ravi. This drain is at present serving as an industrial effluent carrier for fourteen polluting industries, the majority of which are of pulp and paper type. The main objective of this study is to investigate the impact of their effluents on the drain and to suggest measures for control so as to save river Ravi from further pollution. The total effluent discharges from these industries on average basis is 86640 m-3/3. The range of their average characteristics being: pH 7.0 to 7.8, total solids 834 to 2918 mg/L suspended solids 118 to 1096 mg/L total dissolved, solids 08 to 1293 mg/L BODs 9564 to 2000 mg/L and COD 1755 to 3494 mg/L. The values are indicative of very high pollution entering the drain. Condition in the drain was investigated at the upstream and downstream sides and results of the investigations have been summarized. 96 percent increase in BOD and COD load at downstream in attributed to industrial effluent discharges. To certain extent wastewater reuse activity like manufacturing of crude paper board from the sedimented fibrous materials and extraction of oil by local population and going on at site at an increasing rate. Investigations revealed that pollution load of the drain can be reduced to certain extent, if the industries are asked to install sedimentation tanks or primary setting tanks within their premises. Because the majority of the plants are of pulp and paper type, NEQS levels can be achieved by a combined treatment plant consisting of anaerobic WSPs followed by aerated Lagoons at the downstream side.

  13. The possible role of pancreatic proteases in the turnover of intestinal brush border proteins.

    Alpers, D H; Tedesco, F J

    1975-08-05

    1. Intestinal brush border enzymes have heterogeneous rates of turnover, the largest proteins having the fastest turnover. Since the membrane faces the intestinal lumen, the effects of pancreatic factors were examined in mediating this turnover. Surgical subtotal pancreatectomy was used as an experimental model to study the turnover of brush border proteins in the absence of most pancreatic secretions. 2. Subtotal (95%) pancreatectomy of rats was found to cause elevations by about 50% of total activity and specific activities of certain brush border enzymes (maltase, sucrase, lactase), but not of others (alkaline phosphatase, trehalase). Rats were judged to be functionally deficient in pancreatic proteolytic enzymes (a) by demonstration of vitamin B-12 malabsorption, which was corrected by trypsin, and (b) by the finding of only about 20% of proteolytic activity appearing in the lumen after a test meal when compared to control. 3. To measure protein turnover in vivo the method of double labelling was used, where [3H]- and [14C]valine were administered intraduodenally in sequence 10 h apart. With this technique, a high 3H/14C ratio is correlated with rapid turnover. Proteins with apparent molecular weights of about 200 000-270 000 were found to turn over more rapidly than smaller proteins. 3H/14C ranged from 4.7 to 6.2 in animals without pancreatic insufficiency. In the face of decreased pancreatic proteolysis, the 3H/14C ratio was 2.3-3.1, similar to that of proteins with a slow half life. 4. Estimates of relative synthetic rates of large brush border proteins were lower than normal in pancreatectomized animals, but were constant over the period of the labelling experiment. The high enzyme levels in the face of lower synthetic rates confirms that, at the new steady rate, degradation rates must be slower for large brush border proteins in pancreatic insufficiency. 5. In vitro, using purified brush borders, unfractionated pancreatic enzymes were found to remove

    Full Text Available Modernity has been creating spaces, new boundaries and borders, as metaphysical, mythological and symbolic marks of physical and imaginary territories. Modern space and its borders are metaphors, boundaries that are created, walls that rise to identify with some and categorize others. In this short paper we want to approach the problem of the transformation of the idea of border (geographical, cultural, symbolic, etc., for a reflection on the transformations of that civilized obsession called border. The border has always been a reference in facing the identities, names, symbols, different imaginary: it is more confrontational line between two otherness. From the previous framework, we reflect on Turnerian mythology, as we believe that behind the creation of the imagination of the northern border is the mythical vision of the American frontier as ideological canon that explains and confirms the presence of the white race in a border re–made in the image and likeness of the “American Dream”. Frederick Turner’s reflection on the role of the frontier in American history is not only the study of the importance of progress towards the West but –even more so, is the analysis of meaning that had the American frontier as a historical process that ended in 1893, as Turner said, but rather extended into the twentieth century and continues to constantly shaping the process of territorialization of the border.

    A top concern in homeland security efforts is the lack of ability to monitor the thousands of miles of open border with our neighbors. It is not currently feasible to continually monitor the borders for illegal intrusions. The MicroSensor System (MSS) seeks to achieve a low-cost monitoring solution that can be efficiently deployed for border patrol applications. The modifications and issues regarding the unique requirements of this application will be discussed and presented. The MicroSensor System was developed by the Defense Microelectronics Activity (DMEA) for military applications, but border patrol applications, with their unique sensor requirements, demand careful adaptation and modification from the military application. Adaptation of the existing sensor design for border applications has been initiated. Coverage issues, communications needs, and other requirements need to be explored for the border patrol application. Currently, border patrol has a number of deficiencies that can be addressed with a microsensor network. First, a distributed networked sensor field could mitigate the porous border intruder detection problem. Second, a unified database needs to be available to identify aliens attempting to cross into the United States. This database needs to take unique characteristics (e.g. biometrics, fingerprints) recovered from a specialized field unit to reliably identify intruders. Finally, this sensor network needs to provide a communication ability to allow border patrol officers to have quick access to intrusion information as well as equipment tracking and voice communication. MSS already addresses the sensing portion of the solution, including detection of acoustic, infrared, magnetic, and seismic events. MSS also includes a low-power networking protocol to lengthen the battery life. In addition to current military requirements, MSS needs a solar panel solution to extend its battery life to 5 years, and an additional backbone communication link

  1. Effect of the US-Mexico border region in cardiovascular mortality: ecological time trend analysis of Mexican border and non-border municipalities from 1998 to 2012.

    An array of risk factors has been associated with cardiovascular diseases, and developing nations are becoming disproportionately affected by such diseases. Cardiovascular diseases have been reported to be highly prevalent in the Mexican population, but local mortality data is poor. The Mexican side of the US-Mexico border has a culture that is closely related to a developed nation and therefore may share the same risk factors of cardiovascular diseases. We wanted to explore if there was higher cardiovascular mortality in the border region of Mexico compared to the rest of the nation. We conducted a population based cross-sectional time series analysis to estimate the effects of education, insurance and municipal size in Mexican border (n = 38) and non-border municipalities (n = 2360) and its association with cardiovascular age-adjusted mortality rates between the years 1998-2012. We used a mixed effect linear model with random effect estimation and repeated measurements to compare the main outcome variable (mortality rate), the covariates (education, insurance and population size) and the geographic delimiter (border/non-border). Mortality due to cardiovascular disease was consistently higher in the municipalities along the US-Mexico border, showing a difference of 78 · 5 (95% CI 58 · 7-98 · 3, p Mexico border region is disproportionately affected by cardiovascular disease mortality as compared to the non-border region of Mexico. This was not explained by education, population density, or insurance coverage. Proximity to the US culture and related diet and habits can be explanations of the increasing mortality trend.

  3. Advancements in bait technology to control Glossina swynnertoni Austen, the species of limited distribution in Kenya and Tanzania border: A review.

    Nagagi, Yakob P; Silayo, Richard S; Kweka, Eliningaya J

    2017-01-01

    Glossina swynnertoni is a savannah tsetse that is largely confined to the Serengeti-Mara [a very small part of East Africa covering northern Tanzania (Arusha and Manyara regions and parts of Shinyanga and Mara regions) extending Maasai Mara ecosystem in southwestern Kenya]. Nevertheless, it is of great concern to human and animal health and is one of the top target tsetse species for eradication. To achieve this eradication objective, it is important to know about its behaviour so that the appropriate tools/measures especially the right traps can be applied against it. In this paper G. swynnertoni is reviewed in terms of its behaviour, and development of traps for its survey and control. Glossina swynnertoni control is of paramount importance in Tanzania tourism industry and country's income. Since, G. swynnertoni is also distributed in national parks, control is vital as it might reduce tourists excursion/movement, by transmitting the African trypanosomiasis among travelers. Different literature search engines such as Google Scholar and PubMed were deployed for literature search. It was found that the behaviour of G. swynnertoni is relatively similar but unique from other tsetse flies. Its feeding cycle is 2½-3 days as opposed to 3-4 days observed in other tsetse species. The flight activity pattern varied between sex, with male having their peak at 1100-1200 hrs and females 1400-1600 hrs. The activity in both sexes decline rapidly towards the dusk (1700-1800 hrs). It was further that host odours, relatively smaller and vertically oriented devices, as well as host movement are the main attractive factors to this tsetse species, which can be exploited to design efficient artificial devices for control of G. swynnertoni . Therefore, due to its restricted distribution and threat it poses on tourism industry, deliberate efforts need to be made against G. swynnertoni as a next candidate to be eradicated using artificial bait technology.

  8. Do microbial exudates control EH electrode measurements?

    Science.gov (United States)

    Markelova, E.; Parsons, C. T.; Smeaton, C. M.; Van Cappellen, P.

    2017-12-01

    Redox electrodes are widely used as simple, inexpensive monitoring devices to rapidly measure redox potentials (EH) of waterlogged soils, sediments, and aquifers. While a variety of physicochemical and biogeochemical factors have been involved to explain measured EH values, the role of microorganisms remains comparatively understudied and uncertain. Besides catalyzing many inorganic redox reactions (e.g., nitrate reduction), microorganisms produce a variety of redox-active organic compounds (e.g., NAD+/NADH, GSSG/2GSH, FAD/FADH2), which can be released into the surrounding environment via active secretion, passive diffusion, or cell lysis. To isolate different microbial effects on EH measurements, we performed batch experiments using S. oneidensis MR-I as a model heterotrophic microorganism and flavins as example microbial exudates [1]. We monitored EH and pH along with flavin production (fluorescence measurements) during dissimilatory nitrate reduction to ammonium (DNRA). Dissolved flavins increased to 0.2 mM (riboflavin equivalent) under anoxic conditions during complete consumption of 1 mM nitrate by DNRA at pH 7.4 and 30 °C over 80 hours. The observed redox cascade from +255 to -250 mV did not follow the EH predicted for the reduction of NO3- to NO2- and NO2- to NH4+ by the Nernst equation. However, a set of separate abiotic experiments on the photoreduction of synthetic flavins (LMC, RF, FMN, and FAD, Sigma Aldrich) under the same conditions indicated that measured EH values are buffered at +270 ± 20 mV and -230 ± 50 mV when oxidized and reduced flavin species dominate, respectively. Moreover, based on the temporal changes in EH, we speculate that NO3- reduction by S. oneidensis consumes reduced flavins (i.e., NO3- accepts electrons from reduced flavins) and generates oxidized flavins, thus buffering EH at +255 mV. By contrast, NO2- reduction to NH4+ is independent of flavin speciation, which leads to the accumulation of reduced flavins in the solution and

  14. Detection of contaminated metallurgical scrap at borders: a proposal for an 'investigation level'

    International Nuclear Information System (INIS)

    Duftschmid, K.E.

    1999-01-01

    In 1995 the IAEA started a program to combat illicit trafficking in nuclear and other radioactive materials which includes the problem of cross-border movement of contaminated metallurgical scrap. A major activity in this program is the elaboration of a Safety Guide on 'Preventing, Detecting and Responding to Illicit Trafficking', co-sponsored by the World Customs Organization (WCO) and INTERPOL. The guide will provide advice to the Member States, in particular on technical and administrative procedures for detection of radioactive materials at borders. Radiation monitoring systems for contaminated scrap metals have been successfully used in steel plants and larger scrap yards since several years and suitable products are on the market today. Using sophisticated software and dynamic scanning techniques such systems allow for detection of an artificial increase in radiation background level as low as by 20%, even if the natural background signal is substantially suppressed by the vehicle itself entering the monitor. However, the measurement conditions at borders are essentially different from those in plants. Large traffic crossing major borders limits the time for detection and response to a few seconds and multiple checks are nearly impractical. Shielded radioactive sources - even of high activity - which are deeply buried in scrap, cannot be detected without unloading the vehicle, a procedure generally ruled out at borders. Highly sensitive monitoring systems necessarily cause frequent false alarms or nuisance alarms due to innocent radioactive materials such as naturally occurring radioactivity e.g. in fertilizers, scale in pipes used in the oil industry or medical radioisotopes. A particular, rather frequent problem is the unnecessary reject of scrap transports on borders due to the inherent low level contamination of steel with 60 Co, even in sheet metal used for lorries or railroad cars. Such contamination can easily be caused by the routine method to control

    Human control strategy is measured through use of a psychologically-based computer simulation which reflects a broader theory of control behavior. The simulation is called the human operator performance emulator, or HOPE. HOPE was designed to emulate control learning in a one-dimensional preview tracking task and to measure control strategy in that setting. When given a numerical representation of a track and information about current position in relation to that track, HOPE generates positions for a stick controlling the cursor to be moved along the track. In other words, HOPE generates control stick behavior corresponding to that which might be used by a person learning preview tracking.

    In feedback controls, measurement is an essential step in designing protocols according to outcomes. For quantum mechanical systems, measurement has another effect; to supply energy to the measured system. We verify that in feedback-controlled quantum engines, measurement plays a dual role; not only as an auxiliary to perform feedback control but also as an energy supply to drive the engines. We consider a specific engine cycle exploiting feedback control followed by projective measurement and show that the maximum bound of the extractable work is set by both the efficacy of the feedback control and the energy change caused by projective measurement. We take a concrete example of an engine using an immobile spin-1/2 particle as a working substance and suggest two possible scenarios for work extraction.

  18. Changes in the Transnational Family Structures of Mexican Farm Workers in the Era of Border Militarization.

    Historically, undocumented Mexican farm workers migrated circularly, leaving family behind in Mexico on short trips to the United States. Scholars have argued that border militarization has disrupted circular migration as the costs of crossing the border lead to longer stays, increased settlement, and changing transnational family practices. Yet, no study has explored changes in the transnational family structures of Mexico-U.S. migrants that span the era of border militarization. Using data from the National Agricultural Workers Survey, we document a dramatic shift away from transnational family life (as measured by location of residence of dependent children) among undocumented Mexican farm workers and a less dramatic shift among documented Mexican farm workers in the United States between 1993 and 2012. These trends are not explained by changes in the sociodemographic characteristics of farm workers or by changing demographic conditions or rising violence in Mexico. One-half of the trend can be accounted for by lengthened duration of stay and increased connections to the United States among the undocumented, but none of the trend is explained by these measures of settlement among the documented, suggesting that some Mexican farm workers adopt new family migration strategies at first migration. Increases in border control are associated with lower likelihood that children reside in Mexico-a finding that holds up to instrumental variable techniques. Our findings confirm the argument that U.S. border militarization-a policy designed to deter undocumented migration-is instead disrupting transnational family life between Mexico and the United States and, in doing so, is creating a permanent population of undocumented migrants and their children in the United States.

  1. Smuggling and cross border shopping of tobacco in Europe.

    Joossens, L; Raw, M

    1995-05-27

    Governments have recently become concerned about cross border shopping and smuggling because it can decrease tax revenue. The tobacco industry predicted that, with the removal of border controls in the European Union, price differences between neighbouring countries would lead to a diversion of tobacco trade, legally and illegally, to countries with cheaper cigarettes. According to them this diversion would be through increased cross border shopping for personal consumption or through increased smuggling of cheap cigarettes from countries with low tax to countries with high tax, where cigarettes are more expensive. These arguments have been used to urge governments not to increase tax on tobacco products. The evidence suggests, however, that cross border shopping is not yet a problem in Europe and that smuggling is not of cheap cigarettes to expensive countries. Instead, more expensive "international" brands are smuggled into northern Europe and sold illegally on the streets of the cheaper countries of southern Europe.

  2. The Belief in Personal Control Scale: a measure of God-Mediated and Exaggerated Control.

    1987-01-01

    Combining and extending previous conceptions of the construct of perceived control, a self-report measure based on a proposed multidimensional model was developed and validated. The Belief in Personal Control Scale (BPCS), measures of locus of control, depression, mania, anxiety, self-esteem, and social desirability were administered to several samples. A factor analysis revealed three interpretable components of the control construct: a general External Control factor, an Exaggerated Internal Control factor, and a God-Mediated Control factor. The results of this article provide preliminary support for the model and for the BPCS as a multidimensional measure of perceived control with reliable and valid subscales. Consistent with the proposed model of control, the three factors correlated differentially with the various measures of psychological adjustment. Of particular interest is the positive correlation between the Exaggerated Internal Control factor and a measure of mania.

    This paper presents a scenario of legal control of software in measuring instruments. Such control is hampered by intrinsic problems related to software analysis and verification. To circumvent these difficulties, several projects are being developed to attack different stages of legal control, such as the model type approval, periodic verifications and metrological expertise. The proposals that will arise from these projects will be discussed among the parts and may be incorporated into the measuring instruments. (author)

    An Analytical Chemistry Measurements Quality Control Program assures the reliability of analytical measurements performed at the Barnwell Nuclear Fuel Plant. The program includes training, methods quality control, replicate samples and measurements, mass measurements, interlaboratory sample exchanges, and standards preparation. This program has been designed to meet the requirements of 10CFR70.57. Portions of the program have been automated by using a PDP 11/35 computer system to provide features which are not readily available in manual systems. These include such items as realtime measurement control, computer calculated bias and precision estimates, various surveillance applications, and evaluation of measurement system variables. The efficiency of the computer system has been demonstrated in gathering and assimilating the results of over 1100 quality control samples during a recent cold chemical checkout campaign. These data were used to determine equations for predicting measurements reliability estimates; to evaluate measurement performance of the analysts, equipment, and measurement period; and to provide directions for chemistry methods modifications and additional training requirements. A procedure of replicate sampling and measuring provides random error estimates. The analytical chemistry measurement quality control activities during the campaign represented about 10% of the total analytical chemistry effort

    The paper deals with a possible realization of eliminating the effect of noise in scalar hysteresis measurements. The measured signals have been transformed into the frequency domain, and, after applying digital filter, the spectrums of the filtered signals have been transformed back to the time domain. The proposed technique results in an accurate noise-removal algorithm. The paper illustrates a fast controlling algorithm applying the inverse of the actually measured hysteresis loop, and another proportional one to measure distorted flux pattern. By developing the mentioned algorithms, it aims at the controlling of a more complicated phenomena, i.e. measuring the vector hysteresis characteristics

    1999-01-01

    Radiation and radioactive substances are natural and permanent features of the environment; additionally the use of human made radiation is widespread. Sources of radiation are essential to modern health care, disposable medical supplies sterilized by intense radiation have been central to combating disease, radiology is a vital diagnostic tool and radiotherapy is commonly part of the treatment of malignancies. Nuclear techniques are in growing use in industry, agriculture, medicine and many fields of research, benefiting hundreds of millions of people and giving employment to millions of people in the related occupations, Irradiation is used around the world to preserve and reduce wastage and sterilization techniques have been used to eradicate disease carrying insects and pests. Industrial radiography is in routine use, for example to examine welds and detect cracks and help prevent the failure of engineered structures. It is also known that exposure to ionizing radiation can result to injuries that manifest themselves in the individual and his descendants. It is therefore imperative that the use of radiation sources be accompanied with the methods necessary for the prevention of the harmful effects of the radiation. These methods are referred to as control measures. Control measures that have been applied in establishments can be classified into physical control measures and administrative control measures. Physical control measures involve the technical aspects while administrative control measures augment physical measures. The guidelines and recommendations for the safe use of radiation and radioactive materials are provided through legislative and regulatory controls

    Each nation's laws should prohibit development, acquisition, or transfer of WMD-critical items and should make it a crime to violate that prohibition for hostile purposes. Thus, WMD proliferation should be illegal everywhere, powerfully reinforcing the norm against acquisition of such weapons as well as facilitating law enforcement and trans-national legal cooperation. Provisions applicable to threats should be harmonized. National laws should address threats and should ensure prosecution of offenders or extradition to another State for prosecution. The scope of legal jurisdiction over such crimes should broadly reach the behaviour of legal entities in trans-national smuggling and weapons development conspiracies. A priority question is precisely which activity should constitute a criminal offence. It is relatively straightforward to make the use of WMD a crime; but it will be necessary to reach preparatory steps that can encompass innocent behaviour or even legitimate scientific inquiry. Bio-terror preparations, for example, may employ the same materials, equipment and techniques as undertaking legitimate disease research. Standards must be developed to instruct law enforcers as to what behaviour merits criminal investigation to prevent a hostile attack. Similarly, legal measures must define 'WMD' items, including chemical and biological agents that are non-lethal but incapacitating to humans as well as agents that are lethal as to animal or plant life. If WMD proliferation is criminalized, each State's law enforcement officials must work jointly with their counterparts in other States by sharing information, conducting investigations, and prosecuting apprehended terrorists. State cooperation both in gathering intelligence and using that information to prevent criminal activity is undermined, however, by lack of coherent legal instruments. Currently, there is no integrated database of State laws concerning production or use of WMD; it is difficult to know what

    The prevention of hospital acquired pressure ulcers in critically ill patients remains a significant clinical challenge. The aim of this trial was to investigate the effectiveness of multi-layered soft silicone foam dressings in preventing intensive care unit (ICU) pressure ulcers when applied in the emergency department to 440 trauma and critically ill patients. Intervention group patients (n = 219) had Mepilex(®) Border Sacrum and Mepilex(®) Heel dressings applied in the emergency department and maintained throughout their ICU stay. Results revealed that there were significantly fewer patients with pressure ulcers in the intervention group compared to the control group (5 versus 20, P = 0·001). This represented a 10% difference in incidence between the groups (3·1% versus 13·1%) and a number needed to treat of ten patients to prevent one pressure ulcer. Overall there were fewer sacral (2 versus 8, P = 0·05) and heel pressure ulcers (5 versus 19, P = 0·002) and pressure injuries overall (7 versus 27, P = 0·002) in interventions than in controls. The time to injury survival analysis indicated that intervention group patients had a hazard ratio of 0·19 (P = 0·002) compared to control group patients. We conclude that multi-layered soft silicone foam dressings are effective in preventing pressure ulcers in critically ill patients when applied in the emergency department prior to ICU transfer. © 2013 The Authors.

    Accurate lip contour identification is demanding since variations in color, form and surface texture, even in normal lips, introduce artifacts in non-adapted segmentation algorithms. Herein, a method for vermilion border detection and quantification in healthy and diseased lower lips is presented. To quantify the morphological irregularities of lower lip border, to validate its discriminative power in solar cheilosis diagnosis and to provide supportive tools toward, cost effective, non invasive, disease monitoring. Segmentation algorithm for lower lip border was based on spatial fuzzy c-means clustering algorithm with adaptive selection of fuzzy exponent m. Lip features measuring morphological lip border deviations were estimated. The method of lip border extraction and quantitative description was evaluated in a gold standard set of 25 young volunteers without onset of lip diseases. Quantitative descriptors were evaluated in terms of correct classification rates in differentiating 30 healthy control cases from 41 patients with solar cheilosis and were further applied to quantify the therapeutic outcome after immunocryosurgery in eight patients with solar cheilosis. Adaptive estimation of fuzzy exponent m substantially boosted the segmentation quality in gold standard cases yielding quite smooth lip contours and uniformly low values of lip irregularity features. Discriminant analysis highlighted the distance between the extracted and modeled vermilion border as a feature with excellent diagnostic accuracy (sensitivity and specificity 98% and 93% respectively). Results on patients with solar cheilosis followed up after treatment with immunocryosurgery showed that proposed quantitative lip marker was able to trace the improvement of disease after treatment. Correct lip border recognition is the prerequisite for extracting essential morphological descriptors from lips with epithelial diseases like solar cheilosis. In this paper we presented an efficient method for the

    We apply a fixed-effects model to examine the impact of trade and environmental policies on air quality at ports along the U.S.-Mexico border. We control for other factors influencing air quality, such as air quality of cities near the border, volume of traffic flows and congestion. Results show the air quality improved after 2004, when the diesel engine policy was applied. We see mixed results for the trade policy, whose implementation time varies across ports along the international border. Controlling for air quality in cities near the border is essential for assessing the policy contributions to air quality. Copyright © 2010. Published by Elsevier Ltd.

    Due to increasing discrimination and marginalization, Arab Americans are at a greater risk for mental health disorders. Social networks that include ties to the country of origin could help promote mental well-being in the face of discrimination. The role of countries of origin in immigrant mental health receives little attention compared to adjustment in destination contexts. This study addresses this gap by analyzing the relationship between nativity, cross-border ties, and psychological distress and happiness for Arab Americans living in the greater Detroit Metropolitan Area (N=896). I expect that first generation Arab Americans will have more psychological distress compared to one and half, second, and third generations, and Arab Americans with more cross-border ties will have less psychological distress and more happiness. Data come from the 2003 Detroit Arab American Study, which includes measures of nativity, cross-border ties – attitudes, social ties, media consumption, and community organizations, and the Kessler-10 scale of psychological distress and self-reported happiness. Ordered logistic regression analyses suggest that psychological distress and happiness do not vary much by nativity alone. However, cross-border ties have both adverse and protective effects on psychological distress and happiness. For all generations of Arab Americans, cross-border attitudes and social ties are associated with greater odds of psychological distress and for first generation Arab Americans, media consumption is associated with greater odds of unhappiness. In contrast, for all generations, involvement in cross-border community organizations is associated with less psychological distress and for the third generation, positive cross-border attitudes are associated with higher odds of happiness. These findings show the complex relationship between cross-border ties and psychological distress and happiness for different generations of Arab Americans. PMID:26999416

    In order to reduce the time needed to perform control rod calibrations and improve the accuracy of the results, a technique for a measurement, analysis, and tabulation of integral rod worths has been developed. A single series of critical rod positions are determined at constant low power to reduce the waiting time between positive period measurements and still assure true stable reactor period data. Reactivity values from positive period measurements and control rod drop measurements are used as input data for a non-linear fit to the expected control rod integral worth shape. With this method, two control rods can be calibrated in about two hours, and integral and differential calibration tables for operator use are printed almost immediately. Listings of the BASIC computer programs for the non-linear fitting and calibration table preparation are provided. (author)

Proper storage measures and methods can extend the shelf life of the grain. In the process of grain storage, the technical indicators, such as temperature and humidity of the stored grain, indoor temperature and air humidity, should be strictly controlled. The intelligent network-based measurement and control system composed by the PCI bus- based intelligent network interface card, the measurement nodes with the neuron chip as the core and LON bus is used to perform real-time measurement on various condition parameters of the grain bin, and transmit the measurement results to the server over the network for controlling and regulating the device after the server processes the results to ensure the safety of grain storage.

    The consumption of electricity by maquiladora industries in the Mexican border states is an important driver for determining future powerplant needs in that area. An industrial electricity forecasting model is developed for the border states' maquiladoras, and the outputs are compared with a reference forecasting model developed for the US industrial sector, for which considerably more data are available. This model enables the prediction of the effect of implementing various energy efficiency measures in the industrial sector. As an illustration, here the impact of implementing energy-efficient lighting and motors in the Mexican border states' maquiladoras was determined to be substantial. Without such energy efficiency measures, electricity consumption for these industries is predicted to rise by 64% from 2001 to 2010, but if these measures are implemented on a gradual basis over the same time period, electricity consumption is forecast to rise by only 36%.

    The Radiation Safety Without Borders (RSWB) initiative provides peer support to radiation safety professionals in developing countries, which bolsters the country's infrastructure and may lead the way for IRPA Associate membership. The Health Physics Society (HPS) recognizes that many nations do not possess the infrastructure to adequately control and beneficially use ionizing radiation. In a substantial number of countries, organized radiation protection programs are minimal. The RSWB initiative relies on HPS volunteers to assist their counterparts in developing countries with emerging health physics and radiation safety programs, but whose resources are limited, to provide tools that promote and support infrastructure and help these professionals help themselves. RSWB experience to date has shown that by providing refurbished instruments, promoting visits to a HPS venue, or visiting a country just to look provide valuable technical and social infrastructure experiences often missing in the developing nation's cadre of radiation safety professionals. HPS/RSWB with the assistance of the International Atomic Energy Agency (IAEA) pairs chapters with a country, with the expectation that the country's professional radiation safety personnel will form a foreign HPS chapter, and the country eventually will become an IRPA Associate. Although still in its formative stage, RSWB nonetheless has gotten valuable information in spite of the small number of missions. The RSWB initiative continues to have significant beneficial impacts, including: Improving the radiation safety infrastructure of the countries that participate; Assisting those countries without professional radiation safety societies to form one; Strengthening the humanitarian efforts of the United States; Enhancing Homeland Security efforts through improved control of radioactive material internationally. Developing countries, including those in Latin America, underwritten by IAEA, may take advantage of resources

    The problem of radon 222 in buildings as a contributor to radiation exposure is described. Five different control methods and the dose reductions that would result from each are analysed. The annualized cost for each control measure was evaluated and the cost effectiveness of each control measure was calculated on the basis of dollars per person-sievert dose reduction. The use of unipolar ion generators for particle removal appears to be the most cost effective and the use of ceiling fans to increase air circulation the least cost effective. 3 figs., 1 tab

    Full Text Available Abstract Background Recently, wearable technology has been used in various health-related fields to develop advanced monitoring solutions. However, the monitoring function alone cannot meet all the requirements of customizing machine-based exercise on an individual basis by relying on biosignal-based controls. We propose a new wearable unit design equipped with measurement and control functions to support the customization process. Methods The wearable unit can measure the heart rate and electromyogram signals during exercise performance and output workload control commands to the exercise machines. The workload is continuously tracked with exercise programs set according to personally customized workload patterns and estimation results from the measured biosignals by a fuzzy control method. Exercise programs are adapted by relying on a computer workstation, which communicates with the wearable unit via wireless connections. A prototype of the wearable unit was tested together with an Internet-based cycle ergometer system to demonstrate that it is possible to customize exercise on an individual basis. Results We tested the wearable unit in nine people to assess its suitability to control cycle ergometer exercise. The results confirmed that the unit could successfully control the ergometer workload and continuously support gradual changes in physical activities. Conclusion The design of wearable units equipped with measurement and control functions is an important step towards establishing a convenient and continuously supported wellness environment.

    2013-11-01

    Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective, we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border management policies should reflect the change of international context.

  1. Old Borders and New Bordering Capabilities: Cities as Frontier Zones

    Directory of Open Access Journals (Sweden)

    Saskia Sassen

    2015-12-01

    Full Text Available The global city is a new frontier zone. Deregulation, privatization, and new fiscal and monetary policies create the formal instruments to construct their equivalent of the old military “fort”. The city is also a strategic frontier zone for those who lack power, and allows the making of informal politics. At the same time the border is a mix of regimes, marked by protections and opportunities for corporations and high-level professionals, and implies confinement, capture and detention for migrants. The essay discusses the transformation of the city in a frontier zone and analyses the separation between the capabilities entailed by territoriality and the geographic territory tout court. The analysis focuses on the effects of neoliberal policies that, far from making this a borderless world, have actually multiplied the bordered spaces that allow firms and markets to move across conventional borders. Cities are therefore one of the key sites where new neoliberal norms are made and where new identities emerge.

  2. Dynamics of immigration control.

    Djajic, S

    1999-01-01

    This paper examines the dynamic implications of US border control policies and internal enforcement measures for the pattern of illegal immigration and the sectoral allocation of clandestine foreign workers. Efforts to counteract illegal immigration into the US have been increasing steadily following the passage of the Immigration Reform and Control Act of 1986. The purpose of the Act is to reduce illegal immigration with the aid of three instruments: 1) employer sanctions; 2) increased controls along the border; and 3) a legalization program designed to meet the existing demand for agricultural labor in geographic locations that are in proximity of Mexico, the principal source of clandestine foreign labor. The effect of tougher border control measures increases the cost of illegal entry, discouraging clandestine inflows. On the other hand, these measures induce migrants to increase their own anti-detection efforts, reducing the probability of detection and the deportation rate. If the latter effect should dominate, the steady-state stock of clandestine foreign labor will actually increase in response to more vigorous border control measures. Explicit consideration of the role of networks in the clandestine labor market suggests the need for a drastic policy change. This policy change should target illegal migration in areas with high concentrations of clandestine foreign workers. Complementary measures should accompany this policy change to prevent unbalanced enforcement measures.

  3. Metrology and process control: dealing with measurement uncertainty

    Potzick, James

    2010-03-01

    Metrology is often used in designing and controlling manufacturing processes. A product sample is processed, some relevant property is measured, and the process adjusted to bring the next processed sample closer to its specification. This feedback loop can be remarkably effective for the complex processes used in semiconductor manufacturing, but there is some risk involved because measurements have uncertainty and product specifications have tolerances. There is finite risk that good product will fail testing or that faulty product will pass. Standard methods for quantifying measurement uncertainty have been presented, but the question arises: how much measurement uncertainty is tolerable in a specific case? Or, How does measurement uncertainty relate to manufacturing risk? This paper looks at some of the components inside this process control feedback loop and describes methods to answer these questions.

    2008-10-01

    Full Text Available Abstract Background Malaria control in remote, forested areas of the Mekong region relies on personal protection from mosquito bites. Uptake of these methods may be limited by knowledge of the link between mosquitoes and malaria as well as social and economic aspects. Understanding barriers to uptake will inform malaria control programmes on targets for improvement of delivery. Methods A total 748 key respondents: health providers and village heads, from 187 villages and 25 different ethnic groups, were interviewed using structured questionnaires. Differences in use of personal protection, and knowledge of malaria between groups were analysed using chi-square; and binary logistic regression used for multivariate analysis. Results Malaria knowledge was poor with 19.4% of women and 37.5% of men linking mosquitoes with malaria, although 95.6% knew one or more methods of mosquito control. Virtually all respondents used personal protection at some time during the year; and understanding of malaria transmission was strongly associated with bednet use. Those working in forest agriculture were significantly more likely to know that mosquitoes transmit malaria but this did not translate into a significantly greater likelihood of using bednets. Furthermore, use of personal protection while woing outdoors was rare, and less than 3% of respondents knew about the insecticide impregnation of bednets. The use of bednets, synthetic repellents and mosquito coils varied between ethnic groups, but was significantly more frequent among those with higher income, more years of education and permanent housing. The reported use of repellents and coils was also more common among women despite their low knowledge of malaria transmission, and low likelihood of having heard information on malaria within the last year. Conclusion The use of personal protection must be increased, particularly among outdoor workers that have higher malaria risk. However, personal protection

  6. Delayless acceleration measurement method for motion control applications

    Delayless and accurate sensing of angular acceleration can improve the performance of motion control in motor drives. Acceleration control is, however, seldom implemented in practical drive systems due to prohibitively high costs or unsatisfactory results of most acceleration measurement methods. In this paper we propose an efficient and accurate acceleration measurement method based on direct differentiation of the corresponding velocity signal. Polynomial predictive filtering is used to smooth the resulting noisy signal without delay. This type of prediction is justified by noticing that a low-degree polynomial can usually be fitted into the primary acceleration curve. No additional hardware is required to implement the procedure if the velocity signal is already available. The performance of the acceleration measurement method is evaluated by applying it to a demanding motion control application. (orig.) 12 refs.

    2015-01-01

    The purpose of this review is to synthesize the current knowledge on the international movement of patients and biopsied embryo cells for pre-implantation genetic diagnosis and its different applications. Thus far, few attempts have been made to identify the specific nature of this phenomenon called 'cross-border reprogenetic services'. There is scattered evidence, both empirical and speculative, suggesting that these services raise major issues in terms of service provision, risks for patients and the children-to-come, the legal liabilities of physicians, as well as social justice. To compile this evidence, this review uses the narrative overview protocol combined with thematic analysis. Five major themes have emerged from the literature at the conjunction of cross-border treatments and reprogenetics: 'scope', 'scale', 'motivations', 'concerns', and 'governance'. Similar themes have already been observed in the case of other medical tourism activities, but this review highlights their singularity with reprogenetic services. It emphasizes the diagnostic and autologous feature of reprogenetics, the constant risk of misdiagnosis, the restriction on certain tests for medically controversial conditions, and the uncertain accessibility of genetic counseling in cross-border settings. © 2014 John Wiley & Sons A/S.

    1997-09-01

    Yunnan Province, due its international borders with Myanmar, Vietnam and Lao PDR has a large number of imported cases of malaria, including a high proportion of Plasmodium falciparum, as a result of the mobility of the population. This movement is due to workers coming from other provinces where there is no malaria to work in the productive tropical lowlands. Chinese nationals who have gone to work in neighboring countries, border trade and refugees from Myanmar. Much of Yunnan is peopled by ethnic minorities living in remote mountainous and forested areas which are difficult to reach. However, surveillance has been strengthened by training 3,900 primary health care workers and combining the search for visiting foreigners, returning Chinese and people from other provinces with public security, customs formalities and employers. Any visitor detected by these services is obliged to have a blood slide taken. This has resulted in an earlier and more complete detection of malaria cases, reducing incidence from 19.19 to 12.12/10,000 in the border area over the last 10 years. This is despite a considerable increase in population movement and the threat of drug resistant malaria.

    2017-07-01

    Full Text Available Vampire bat-transmitted rabies was first recognized in Trinidad during a major outbreak reported in 1925. Trinidad is the only Caribbean island with vampire bat-transmitted rabies. We conducted a literature review to describe the changing epidemiology of rabies in Trinidad and give a historical perspective to rabies prevention and control measures on the island. The last human case of rabies occurred in 1937 and although no case of canine-transmitted rabies was reported since 1914, sporadic outbreaks of bat-transmitted rabies still occur in livestock to date. Over the last century, seven notable epidemics were recorded in Trinidad with the loss of over 3000 animals. During the 1950s, several measures were effectively adopted for the prevention and control of the disease which led to a significant reduction in the number of cases. These measures include: vampire bat population control, livestock vaccination, and animal surveillance. However, due to lapses in these measures over the years (e.g., periods of limited vampire control and incomplete herd vaccination, epidemics have occurred. In light of the significant negative impact of rabies on animal production and human health, rabies surveillance in Trinidad should be enhanced and cases evaluated towards the design and implementation of more evidence-based prevention and control programs.

    Full Text Available Abstract Background Clinicians need a practical, objective test of postural control that is sensitive to mild neurological disease, shows experimental and clinical validity, and has good test-retest reliability. We developed an instrumented test of postural sway (ISway using a body-worn accelerometer to offer an objective and practical measure of postural control. Methods We conducted two separate studies with two groups of subjects. Study I: sensitivity and experimental concurrent validity. Thirteen subjects with early, untreated Parkinson’s disease (PD and 12 age-matched control subjects (CTR were tested in the laboratory, to compare sway from force-plate COP and inertial sensors. Study II: test-retest reliability and clinical concurrent validity. A different set of 17 early-to-moderate, treated PD (tested ON medication, and 17 age-matched CTR subjects were tested in the clinic to compare clinical balance tests with sway from inertial sensors. For reliability, the sensor was removed, subjects rested for 30 min, and the protocol was repeated. Thirteen sway measures (7 time-domain, 5 frequency-domain measures, and JERK were computed from the 2D time series acceleration (ACC data to determine the best metrics for a clinical balance test. Results Both center of pressure (COP and ACC measures differentiated sway between CTR and untreated PD. JERK and time-domain measures showed the best test-retest reliability (JERK ICC was 0.86 in PD and 0.87 in CTR; time-domain measures ICC ranged from 0.55 to 0.84 in PD and from 0.60 to 0.89 in CTR. JERK, all but one time-domain measure, and one frequency measure were significantly correlated with the clinical postural stability score (r ranged from 0.50 to 0.63, 0.01 Conclusions Based on these results, we recommend a subset of the most sensitive, reliable, and valid ISway measures to characterize posture control in PD: 1 JERK, 2 RMS amplitude and mean velocity from the time-domain measures, and 3 centroidal

We show that an arbitrary state can indeed be prepared, provided that the available measurements satisfy certain requirements. Our results shed light on the role that measurement-induced back-action plays in quantum feedback control and the extent to which this back-action can be exploited in quantum-control protocols.

    Full Text Available Border issues have always been an inherent part of the Post-Soviet realities within Central Asia. Since the collapse of the Soviet Union, Central Asia had to face numerous structural challenges including the management of the borders. Today when all five Central Asian countries are celebrating the 25th anniversary of their independence, there are significant border issues that remain unresolved and in most cases are overcomplicated. Over the years many disputed parts of the borders emerged, predominantly in the Fergana valley, where Kyrgyzstan, Tajikistan and Uzbekistan territories meet, converge and in some cases clash. All three Republics found themselves with some portion of the territory whose population could not identify itself with the host nation. What was once in fact a part of a single country run from Moscow that easily handled any slight ethnic territorial, political and economic tensions, now it is under the control of three different countries with different legislation, foreign policies and approaches to border management and regulation

    2015-12-01

    Full Text Available Common unique ETRS89 coordinates of the state boundaries are crucial for cross-border data harmonization for international projects. In the frame of European Location Framework (ELF project Czech Office for Surveying, Mapping and Cadastre (ČÚZK cooperates with Poland on egde-matching on the state border. During the preliminary phase of the project was some difficulty identified. If the state boundary is measured and administered in the national coordinate system, the accuracy of the transformation into the ETRS89 is influenced by discrepancies of the local trigonometric network, which results in two slightly different state boundaries. Final solution for Europe – international treaties on the state borders based on the ETRS89 coordinates – is necessary, but it will take years.

    2018-01-20

    The goal of this work was to experimentally quantify the uncertainty of three-dimensional (3D) and three-component (3C) velocity measurements using tomographic particle image velocimetry (tomo-PIV). Controlled measurements were designed using tracer particles embedded in a solid sample, and tomo-PIV measurements were performed on the sample while it was moved both translationally and rotationally to simulate various known displacement fields, so the 3D3C displacements measured by tomo-PIV can be directly compared to the known displacements created by the sample. The results illustrated that (1) the tomo-PIV technique was able to reconstruct the 3D3C velocity with an averaged error of 0.8-1.4 voxels in terms of magnitude and 1.7°-1.9° in terms of orientation for the velocity fields tested; (2) view registration (VR) plays a significant role in tomo-PIV, and by reducing VR error from 0.6° to 0.1°, the 3D3C measurement accuracy can be improved by at least 2.5 times in terms of both magnitude and orientation; and (3) the use of additional cameras in tomo-PIV can extend the 3D3C velocity measurement to a larger volume, while maintaining acceptable accuracy. These results obtained from controlled tests are expected to aid the error analysis and the design of tomo-PIV measurements.

    Boisde, G; Blanc, F; Perez, J J

    1988-02-01

    Several aspects of remote in situ spectrophotometric measurement by means of optical fibers are considered in the context of chemical process control. The technique makes it possible to measure a species in a particular oxidation state, such as plutonium(VI), sequentially, under the stringent conditions of automated analysis. For the control of several species in solution, measurements at discrete wavelengths on the sides of the absorption peaks serve to increase the dynamic range. Examples are given concerning the isotopic separation of uranium in the Chemex process. The chemical control of complex solutions containing numerous mutually interfering species requires a more elaborate spectral scan and real-time processing to determine the chemical kinetics. Photodiode array spectrophotometers are therefore ideal for analysing the uranium and plutonium solutions of the Purex process. Remote on-line control by ultraviolet monitoring exhibits limitations chiefly due to Rayleigh scattering in the optical fibers. The measurement of pH in acidic (0.8-3.2) and basic media (10-13) has also been attempted. Prior calibration, signal processing and optical spectra modeling are also discussed.

    2011-01-01

    Power-Over-Ethernet (PoE) technology (IEEE standard 802.3af) allows Remote Measurement and Control in harsh environment where human access is difficult in various nuclear research fields. The terminal measurement and control unit receives power for its operation and communicates data over the same LAN cable, without needing to provide power supplies from different source. Almost all data acquisition systems require both data connectivity and a power supply. In a familiar example, telephones are powered from the telephone exchange through the same twisted pair that carries the voice. Now we can do the same thing with Ethernet devices by combining power and data. Only one set of wires is required to bring to the end measurement and control unit which will simplify installation and save space. Remote unit can be easily moved, to wherever a LAN cable can be laid with minimal disruption to the workplace. It is safer as no mains supply is required. Uninterrupted power supply can be guaranteed to the terminal unit during mains power failure. The terminal unit can be shut down and reset remotely without needing for a reset button and power switch. Simple Network Management Protocol (SNMP) can be used to monitor and control the remote unit. PoE will enable to deploy many more embedded systems in nuclear and other industry like Voice over Internet Protocol (VoIP), Security Camera, Tele-information System, Remote Access Control System, Intruder Detection System, and Tele-Medicine System, etc. (author)

  8. Border adjustment for European emissions trading: Competitiveness and carbon leakage

    Unilateral or sub-global policies to combat climate change are potentially sensitive to free-riding and carbon leakage. One way of dealing with carbon leakage and competitiveness is the imposition of border adjustment measures for competing imports, for example in the form of the obligation to importers of goods to purchase and surrender emissions allowances to the authorities when importing. In this paper, we explore some implications of border adjustment measures in the EU ETS, for sectors that might be subject to carbon leakage. We examine the implications of two variants of these measures on the competitiveness of these sectors and on the global environment with the help of a multi-sector, multi-region computable general equilibrium (CGE) model of the global economy. Our calculations suggest that border adjustment might reduce the sectoral rate of leakage of the iron and steel industry rather forcefully, but that the reduction would be less for the mineral products sector, including cement. The reduction of the overall or macro rate of leakage would be modest. So, from an environmental point of view border tax adjustments would not be a very effective policy measure, but might mainly be justified by considerations of sectoral competitiveness.

    Full Text Available Nowdays, using the concentrated sunlight is a big issue because the amount of energy is very high and the light is concentrated in a very small area. The main problem in this situation is the heating, and in order to make safe measurements a remote controlled robot is needed. After that, a remote controlled robot will assume the duty of protect the measured sample and to expose it for a precise time to the concentrated sun in order to reduce heating of the sample. For easy operating, and for automatize the process, all the duties, starting with initial conditions, continuing with triggering the measurements, and conditioning the signals and finalizing with data saving must be assured by the robot.

  12. Spectrally controlled interferometry for measurements of flat and spherical optics

    Salsbury, Chase; Olszak, Artur G.

    2017-10-01

    Conventional interferometry is widely used to measure spherical and at surfaces with nanometer level precision but is plagued by back reflections. We describe a new method of isolating the measurement surface by controlling spectral properties of the source (Spectrally Controlled Interferometry - SCI). Using spectral modulation of the interferometer's source enables formation of localized fringes where the optical path difference is non-zero. As a consequence it becomes possible to form white-light like fringes in common path interferometers, such as the Fizeau. The proposed setup does not require mechanical phase shifting, resulting in simpler instruments and the ability to upgrade existing interferometers. Furthermore, it allows absolute measurement of distance, including radius of curvature of lenses in a single setup with possibility of improving the throughput and removing some modes of failure.

    1980-01-01

    The electronic circuits of two digital temperature meters developed for the thermocouple of Ni-NiCr type are described. The output thermocouple signal as converted by means of voltage-to-freguency converter. The frequency is measured by a digital scaler controled by quartz generator signals. One of the described meter is coupled with digital temperature controler which drives the power stage of the reactor rig heater. The internal rig temperature is measured by the thermocouple providing the input signal to the mentioned voltage-to-frequency converter, that means the circuits work in the negative feedback loop. The converter frequency-to-voltage ratio is automatically adjusted to match to thermocouple sensitivity changes in the course of the temperature variations. The accuracy of measuring system is of order of +- 1degC for thermocouple temperature changes from 523 K up to 973 K (50degC up to 700degC). (author)

    Jacobson, Jake H; Boon, June A; Bright, Janice M

    2013-06-01

    The objectives of this study were to obtain standard echocardiographic measurements from healthy Border Collies and to compare these measurements to those previously reported for a general population of dogs. Standard echocardiographic data were obtained from twenty apparently healthy Border Collie dogs. These data (n = 20) were compared to data obtained from a general population of healthy dogs (n = 69). Border Collies were deemed healthy based on normal history, physical examination, complete blood count, serum biochemical profile, electrocardiogram, and blood pressure, with no evidence of congenital or acquired heart disease on echocardiographic examination. Standard two dimensional, M-mode, and Doppler echocardiographic measurements were obtained and normal ranges determined. The data were compared to data previously obtained at our hospital from a general population of normal dogs. Two dimensional, M-mode, and Doppler reference ranges for healthy Border Collies are presented in tabular form. Comparison of the weight adjusted M-mode echocardiographic means from Border Collies to those from the general population of dogs showed Border Collies to have larger left ventricular systolic and diastolic dimensions, smaller interventricular septal thickness, and lower fractional shortening. There are differences in some echocardiographic parameters between healthy Border Collies and the general dog population, and the echocardiographic reference ranges provided in this study should be used as breed specific reference values for Border Collies.

    Full Text Available OBJETIVE: To determine prevalence of blood pressure control, hypertension, hypertension awareness, and antihypertensive treatment among adults (> 18 years old with diabetes living in the border region between the United States of America and Mexico, and to explore variation in those variables between all adults on the Mexican side of the border ("Mexicans" and three groups on the U.S. side of the border ("all U.S. adults," "U.S.-born Hispanics," and "Mexican immigrants". METHODS: Using data from Phase I (February 2001-October 2002 of the U.S.-Mexico Border Diabetes Prevention and Control Project, a prevalence study of type 2 diabetes and its risk factors, age-adjusted prevalence of hypertension-related variables was calculated for the sample (n = 682 and differences between the border groups were examined through logistic regression. RESULTS: Less than one-third of the sample had controlled blood pressure (140/90 mm Hg, and hypertension awareness and treatment were inadequate. After adjusting for demographics, body mass index, and access to health care, there were no differences in blood pressure control, hypertension, hypertension awareness, or treatment between Mexicans and both U.S. adults and Mexican immigrants. However, compared to Mexicans and Mexican immigrants, U.S.-born Hispanics, particularly younger individuals, had the lowest rates of blood pressure control (17.3% and the highest rates of coexisting hypertension (54.8%. Compared to Mexicans, U.S.-born Hispanics had lower odds of controlled blood pressure (odds ratio [OR] 0.30, 95% confidence interval [CI] 0.09-0.95 and greater odds of hypertension (OR 3.75, 95% CI 1.51-9.29 and hypertension awareness (OR 6.19, 95% CI 1.46-26.15. CONCLUSION: Co-occurrence of diabetes and hypertension is a major public health problem among U.S.-Mexico border residents. The low rate of blood pressure control among various border groups, especially younger U.S.-born Hispanics, suggests that initiatives

    Full Text Available Abstract Background An array of risk factors has been associated with cardiovascular diseases, and developing nations are becoming disproportionately affected by such diseases. Cardiovascular diseases have been reported to be highly prevalent in the Mexican population, but local mortality data is poor. The Mexican side of the US-Mexico border has a culture that is closely related to a developed nation and therefore may share the same risk factors of cardiovascular diseases. We wanted to explore if there was higher cardiovascular mortality in the border region of Mexico compared to the rest of the nation. Methods We conducted a population based cross-sectional time series analysis to estimate the effects of education, insurance and municipal size in Mexican border (n = 38 and non-border municipalities (n = 2360 and its association with cardiovascular age-adjusted mortality rates between the years 1998–2012. We used a mixed effect linear model with random effect estimation and repeated measurements to compare the main outcome variable (mortality rate, the covariates (education, insurance and population size and the geographic delimiter (border/non-border. Results Mortality due to cardiovascular disease was consistently higher in the municipalities along the US-Mexico border, showing a difference of 78 · 5 (95% CI 58 · 7-98 · 3, p < 0 · 001 more cardiovascular deaths after adjusting for covariates. Larger municipal size and higher education levels showed a reduction in cardiovascular mortality of 12 · 6 (95% CI 11 · 4-13 · 8, p < 0 · 001 deaths and 8 · 6 (95% CI 5 · 5-11 · 8, p < 0 · 001 deaths respectively. Insurance coverage showed an increase in cardiovascular mortality of 3 · 6 (95% CI 3 · 1-4 · 0, p < 0 · 001 deaths per decile point increase. There was an increase in cardiovascular mortality of 0 · 3 (95% CI −0 · 001-0 · 6

  18. Dynamical Behaviors of Rumor Spreading Model with Control Measures

    2014-01-01

    Full Text Available Rumor has no basis in fact and flies around. And in general, it is propagated for a certain motivation, either for business, economy, or pleasure. It is found that the web does expose us to more rumor and increase the speed of the rumors spread. Corresponding to these new ways of spreading, the government should carry out some measures, such as issuing message by media, punishing the principal spreader, and enhancing management of the internet. In order to assess these measures, dynamical models without and with control measures are established. Firstly, for two models, equilibria and the basic reproduction number of models are discussed. More importantly, numerical simulation is implemented to assess control measures of rumor spread between individuals-to-individuals and medium-to-individuals. Finally, it is found that the amount of message released by government has the greatest influence on the rumor spread. The reliability of government and the cognizance ability of the public are more important. Besides that, monitoring the internet to prevent the spread of rumor is more important than deleting messages in media which already existed. Moreover, when the minority of people are punished, the control effect is obvious.

    2012-12-01

    The paper presents an anti-lock braking system (ABS) control logic based on the measurement of the longitudinal forces at the hub bearings. The availability of force information allows to design a logic that does not rely on the estimation of the tyre-road friction coefficient, since it continuously tries to exploit the maximum longitudinal tyre force. The logic is designed by means of computer simulation and then tested on a specific hardware in the loop test bench: the experimental results confirm that measured wheel force can lead to a significant improvement of the ABS performances in terms of stopping distance also in the presence of road with variable friction coefficient.

    2003-01-01

    The ISIS 800 MeV proton synchrotron presently provides 2.5*10/sup 13/ protons per pulse at 50 Hz, corresponding to a mean power of 160 kW. A dual harmonic RF system upgrade, now being installed, is expected to increase the intensity and power to about 3.75*10/sup 13/ ppp and 240 kW respectively. This paper describes work presently underway to understand and optimise beam loss control, which is a dominant factor determining operational performance. The main features of the collimation system are described, and Monte Carlo simulations of the loss control process are used to understand variations of efficiency with beam loss mode (growth rate, plane). Results of simulations are compared with measurements and operational data. Improvements to measurements are also outlined.

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Nonlinear model predictive control has been established as a powerful methodology to provide feedback for dynamic processes over the last decades. In practice it is usually combined with parameter and state estimation techniques, which allows to cope with uncertainty on many levels. To reduce the uncertainty it has also been suggested to include optimal experimental design into the sequential process of estimation and control calculation. Most of the focus so far was on dual control approaches, i.e., on using the controls to simultaneously excite the system dynamics (learning as well as minimizing a given objective (performing. We propose a new algorithm, which sequentially solves robust optimal control, optimal experimental design, state and parameter estimation problems. Thus, we decouple the control and the experimental design problems. This has the advantages that we can analyze the impact of measurement timing (sampling independently, and is practically relevant for applications with either an ethical limitation on system excitation (e.g., chemotherapy treatment or the need for fast feedback. The algorithm shows promising results with a 36% reduction of parameter uncertainties for the Lotka-Volterra fishing benchmark example.

  8. Nuclear risk behind the border?

    International Nuclear Information System (INIS)

    Varjoranta, T.

    1995-01-01

    The condition of nuclear wastes and facilities in Russia and in the Baltic countries arouses concern in Finland. Russia has two large nuclear power plants, nuclear weapons, over 300 nuclear submarine reactors and more than ten icebreaker reactors in close proximity to Finland's eastern border. The Lithuanian Ingalina nuclear power plant is also situated close to Finland. Following the Chernobyl accident, considerable improvements have been made to the technology and safety culture of Russian nuclear power plants, for instance, through international support programmes. The unstable social climate in Russia is, however, slowing progress down. Yet it is certain that no accident in the power plants near Finland's borders would cause immediate health risks in Finland, or would threaten the health of large numbers of people in the long term, either. Russia has not always taken proper care of its nuclear waste. In particular, spent fuel from nuclear submarines stored in Northern Russia causes problems. Russians have disposed of some waste by dumping ship reactors, with their fuel, into the Arctic Ocean. Some nuclear-powered submarines have sunk with all their crew. Russia has also conducted many nuclear tests in the vicinity of Finland. (orig.)

    Full Text Available The use of tobacco products is a major problem having a serious effect on public health. Deaths from external causes are those that can be prevented by ensuring environmental safety and educating the society about the effect of lifestyle habits and behaviour on health of an individual. Not only research data reveal the prevalence of tobacco use but also the rate of tobacco sales. Tobacco industry marketing includes advertising, sales promotion and sponsorship strategies that are aimed at promotion of tobacco use. Demand for tobacco products is influenced also by changes in legislation relating to ban on tobacco advertising and sponsorship. Therefore it is necessary to introduce an agreed strategy for reducing tobacco use. The countries that have ratified the World Health Organisation (WHO Framework Convention on Tobacco Control (the Convention should develop and implement an effective tobacco control programme. In Latvia the number of daily smokers gradually decreases thanks to the extensive smoking restrictions though tobacco manufacturers use all the available media, radio and television, newspapers, magazines, advertisements and Internet, to advertise their products. Therefore in order to combat the prevalence of smoking first of all it is necessary to limit cigarette marketing and sales and to carry out monitoring and development of tobacco control measures on the state level. The sales of legal cigarettes have decreased in Latvia starting from 2009. However, the increase in tax rates and prices has contributed to the movement of illegal goods therefore it is necessary to take additional restrictive measures concerning the movement of illegal goods. Though amendments to legislation of Latvia relating to tobacco control comply with the requirements of the WHO Convention it is necessary to evaluate the efficiency of control measures and to improve them. Systematic and comprehensive education of the public is required to encourage the change of

    2015-01-01

    After having described the vicious circle existing between disarmament and security as it appeared before and during the first World War, the author deals with the specific case of nuclear disarmament as it was first addressed just after the Second World War, and was then not accepted by the Russians. He comments the political and strategical approach adopted by the Kennedy administration, notably within the context of severe crises (Berlin and Cuba). This resulted in the re-establishment of a relationship between war and policy as defined by Clausewitz, but based on a trilogy of three inseparable pairs: deterrence and armament control, armament control and non proliferation, armament control and confidence-building measures. The author shows that this trilogy has been somehow operating until the end of Cold War, and that nothing works anymore since the end of Cold War and of the bipolar world

    Gorter, Rosalie; Fox, Jean-Paul; Apeldoorn, Adri; Twisk, Jos

    2016-11-01

    In randomized controlled trials (RCTs), outcome variables are often patient-reported outcomes measured with questionnaires. Ideally, all available item information is used for score construction, which requires an item response theory (IRT) measurement model. However, in practice, the classical test theory measurement model (sum scores) is mostly used, and differences between response patterns leading to the same sum score are ignored. The enhanced differentiation between scores with IRT enables more precise estimation of individual trajectories over time and group effects. The objective of this study was to show the advantages of using IRT scores instead of sum scores when analyzing RCTs. Two studies are presented, a real-life RCT, and a simulation study. Both IRT and sum scores are used to measure the construct and are subsequently used as outcomes for effect calculation. The bias in RCT results is conditional on the measurement model that was used to construct the scores. A bias in estimated trend of around one standard deviation was found when sum scores were used, where IRT showed negligible bias. Accurate statistical inferences are made from an RCT study when using IRT to estimate construct measurements. The use of sum scores leads to incorrect RCT results. Copyright © 2016 Elsevier Inc.

  14. Automatic control system for measuring currents produced by ionization chambers

    International Nuclear Information System (INIS)

    Brancaccio, Franco

    2002-01-01

    Ionization Chambers in current mode operation are usually used in Nuclear Metrology. Activity measurements are quickly performed by Ionization Chambers, with very good precision. For this purpose measurements of very low ionization currents, carried out by high quality instrumentation, are required. Usually, electrometers perform the current integration method under command of signals from an automation system, in order to reduce the measurement uncertainties. Among the measurement systems at the Laboratorio de Metrologia Nuclear (LMN) of IPEN, there are two ionization chamber systems. In the present work, an automation system developed for current integration measurements is described. This automation system is composed by software (graphic interface and control) and an electronic module connected to a microcomputer, by means of a commercial data acquisition card. Several test measurements were performed in order to determine the intrinsic uncertainty, linearity and stability of the system. Using calibrated radioactive solutions, the IG12/A20 chamber calibration factors for 18 F and 153 Sm were obtained, making possible to determine activities of these radionuclides. (author)

  15. Observer-based Coal Mill Control using Oxygen Measurements

    This paper proposes a novel approach to coal flow estimation in pulverized coal mills, which utilizes measurements of oxygen content in the flue gas. Pulverized coal mills are typically not equipped with sensors that detect the amount of coal injected into the furnace. This makes control...... into the furnace and oxygen concentration in the flue gas is designed to estimate the actual coal flow injected into the furnace. With this estimate, it becomes possible to close an inner loop around the coal mill itself, thus giving a better disturbance rejection capability.

  17. The Borders of "Shopluk" and/or Shops without Borders

    Directory of Open Access Journals (Sweden)

    P. Hristov

    2015-08-01

    Full Text Available A historic and cultural region exists at the heart of the Balkans, known in geographic and ethnographic research as Shopluk. This is a region in which, over the last 150 years, state boundaries were moved several times as a result of 5 different wars. Today, the historic Shopluk is where the borders of three nations converge – Republic of Bulgaria, Republic of Serbia and the Republic of Macedonia – and, during the last decade, the region was declared one of the “Euroregions” on the Balkans. Despite the historical similarities in traditional culture and language of this population, in the 19th century it became a subject of nationalist ambitions and a propaganda “wars” between the new national states of Serbia and Bulgaria. The joining of Bulgarian-inhabited parts of Shopluk (the regions of today’s Dimitrovgrad and Bosilegrad in Serbia to the Kingdom of Serbs, Slovenes and Croats in 1919 created a long-lasting tension between the two countries, some residues of which can be felt in everyday relations even today. On the other hand, it has been a century-long tradition for men in this region to take part in seasonal labour migrations all over the Balkan Peninsula, despite political borders. In this way, preserving their cultural and lingual specifics, the groups of seasonal workers – migrants from Shopluk, became a bridge for cultural interaction and exchange with other regions in the neighbour countries. Even though today the population of Shopluk exhibits different national identities, historical similarities in culture and language can turn the Euroregion between Nish, Sofia and Skopje from one of the poorest on the Balkans to one of the most integrated and prosperous.

    Fischer, H.; Blieck, L.; Jescheck, M.; Neubert, W.; Kunze, D.

    1990-01-01

    The publication refers to the new VDE/VDI guideline 3511 and explains its practical intentions and implications by thoroughly discussing the applications of temperature sensors and their limits of use. The current state of the art in temperature measuring is fully described by the discussion of the new temperature scale introduced recently, the ITS '90. The authors of the book look in detail at the particular requirements and conditions of infrared measuring techniques using radiation thermometers as defined in DIN 5496, the applications of microprocessors (DIN-measuring-field-bus, etc.), time program emitters, and measuring transducers (EX ib, etc.). A full chapter has been devoted to the subject of surface temperature measurement. Examples referring to practical applications in industry serve as an introduction to thermal control engineering, in particular with infrared sensors, for processes such as thermal forming. New, optical thermometers for the low temperature range have been given much attention. An annex presents comprehensive tables for calculation and conversion of thermal quantities.

    2013-12-01

    The Eastern border of the European Union (EU) consists of 10 countries after the expansion of the EU in 2004 and 2007. These 10 countries border to the East to countries with high tuberculosis (TB) notification rates. We analyzed the notification data of Europe to quantify the impact of cross-border TB at the Eastern border of the EU. We used TB surveillance data of 2010 submitted by 53 European Region countries to the European Centre for Disease Prevention and Control and the World Health Organization Regional Office for Europe. Notified TB cases were stratified by origin of the case (national/foreign). We calculated the contribution of foreign to overall TB notification. In the 10 EU countries located at the EU Eastern border, 618 notified TB cases (1.7% of all notified TB cases) were of foreign origin. Of those 618 TB cases, 173 (28.0%) were from countries bordering the EU to the East. More specifically, 90 (52.0%) were from Russia, 33 (19.1%) from Belarus, 33 (19.1%) from Ukraine, 13 (7.5%) from Moldova and 4 (2.3%) from Turkey. Currently, migrants contribute little to TB notifications in the 10 EU countries at the Eastern border of the EU, but changes in migration patterns may result in an increasing contribution. Therefore, EU countries at the Eastern border of the EU should strive to provide prompt diagnostic services and adequate treatment of migrants.

  2. Air-Sea Interaction Measurements from the Controlled Towed Vehicle

    2014-12-01

    The Controlled Towed Vehicle (CTV) uses improved towed drone technology to actively maintain via a radar altimeter and controllable wing a user-set height that can be as low as the canonical reference height of 10 m above the sea surface. After take-off, the drone is released from the tow aircraft on a ~700-m stainless steel cable. We have instrumented the 0.23 m diameter and 2.13 m long drone with high fidelity instruments to measure the means and turbulent fluctuations of 3-D wind vector, temperature, humidity, pressure, CO2 and IR sea surface temperature. Data are recorded internally at 40 Hz and simultaneously transmitted to the tow aircraft via dedicated wireless Ethernet link. The CTV accommodates 40 kg of instrument payload and provides it with 250 W of continuous power through a ram air propeller-driven generator. Therefore its endurance is only limited by that of the tow aircraft.We will discuss the CTV development, the engineering challenges and solutions that have been successfully implemented to overcome them. We present results from recent flights as low as 9 m over the coastal ocean and comparisons of profiles and turbulent fluxes from the CTV and the tow aircraft. Manned aircraft operation at low-level boundary-layer flights is very limited. Dropsondes and UAS (Unmanned Aerial Systems) and UAS are alternates for measurements near the ocean surface. However, dropsondes have limited sensor capability and do not measure fluxes, and most present UAS vehicles do not have the payload and power capacity nor the low-flying ability in high winds over the oceans. The CTV therefore, fills a needed gap between the dropsondes, in situ aircraft, and UAS. The payload, capacity and power of the CTV makes it suitable for a variety of atmospheric research measurements. Other sensors to measure aerosol, chemistry, radiation, etc., could be readily accommodated in the CTV.

  11. Problems concerned with scrap metal monitoring at borders

    International Nuclear Information System (INIS)

    Duftschmid, K.E.

    1997-01-01

    Since the early 1980's numerous incidents have been reported in which radioactive material or empty labelled containers for radioactive sources have been found in scrap metal. Apart from the potential health hazard to employees and the general public resulting costs for decontamination, shutdown of production and waste of products already amounted to multi-million dollar figures. Since the opening of the ''iron border'' in Europe, incidents of illicit trafficking of radioactive sources across borders and contamination of scrap metal imported from the former ''Eastern Countries'' have considerably increased, as a result of the lack of a suitable radiation protection infrastructure in some of these countries. This initiated monitoring of scrap metal transports at the borders of several European countries, such as Austria, Finland, Germany and Italy. Up to now neither universally accepted clearance levels for scrap contamination, nor an agreed standardised procedure for its control exist, although the IAEA as well as the European Commission have proposed some recommendations. As a pragmatic solution for border monitoring it is suggested to apply, as practical clearance level, a dose rate on the outside of the vehicle in the order of 0,1 μSv/h, which is approximately equivalent to double natural environmental background. This dose rate would correspond to an activity concentration for 60 Co in the order of 1 kBq/kg and therefore be in a tolerable range, even in view of products coming in close contact with the public.

  12. Role of measurements in material control and accountability (abstract)

    International Nuclear Information System (INIS)

    Mahmud, T.

    2011-01-01

    Analytical techniques are widely used for verification and accountancy of nuclear materials. Nuclear Material (NM) inventories are based on sampling followed by Destructive Analysis. Destructive Analyses range from traditional chemical techniques to recent implementations of radiometric methods. These techniques are performed to quantify the amount of nuclear material (elemental assay and isotopic composition) present in a specific item, container, or in some cases facility and resolving shipper-receiver differences. Analytical techniques used for the MC and A of nuclear material normally require more attention than that for process control because the largest contribution to Material Unaccounted For is in measurement uncertainty. Therefore analytical techniques selected for material control and accountability are highly precise and they comply with accepted 'International Target Values 2010'. (author)

  13. Development of an integrated control and measurement system

    International Nuclear Information System (INIS)

    Manges, W.W.

    1984-03-01

    This thesis presents a tutorial on the issues involved in the development of a minicomputer-based, distributed intelligence data acquisition and process control system to support complex experimental facilities. The particular system discussed in this thesis is under development for the Atomic Vapor Laser Isotope Separation (AVLIS) Program at the Oak Ridge Gaseous Diffusion Plant (ORGDP). In the AVLIS program, we were careful to integrate the computer sections of the implementation into the instrumentation system rather than adding them as an appendage. We then addressed the reliability and availability of the system as a separate concern. Thus, our concept of an integrated control and measurement (ICAM) system forms the basis for this thesis. This thesis details the logic and philosophy that went into the development of this system and explains why the commercially available turn-key systems generally are not suitable. Also, the issues involved in the specification of the components for such an integrated system are emphasized

  14. Accurate fluid force measurement based on control surface integration

    Science.gov (United States)

    Lentink, David

    2018-01-01

    Nonintrusive 3D fluid force measurements are still challenging to conduct accurately for freely moving animals, vehicles, and deforming objects. Two techniques, 3D particle image velocimetry (PIV) and a new technique, the aerodynamic force platform (AFP), address this. Both rely on the control volume integral for momentum; whereas PIV requires numerical integration of flow fields, the AFP performs the integration mechanically based on rigid walls that form the control surface. The accuracy of both PIV and AFP measurements based on the control surface integration is thought to hinge on determining the unsteady body force associated with the acceleration of the volume of displaced fluid. Here, I introduce a set of non-dimensional error ratios to show which fluid and body parameters make the error negligible. The unsteady body force is insignificant in all conditions where the average density of the body is much greater than the density of the fluid, e.g., in gas. Whenever a strongly deforming body experiences significant buoyancy and acceleration, the error is significant. Remarkably, this error can be entirely corrected for with an exact factor provided that the body has a sufficiently homogenous density or acceleration distribution, which is common in liquids. The correction factor for omitting the unsteady body force, {{{ {ρ f}} {1 - {ρ f} ( {{ρ b}+{ρ f}} )}.{( {{{{ρ }}b}+{ρ f}} )}}} , depends only on the fluid, {ρ f}, and body, {{ρ }}b, density. Whereas these straightforward solutions work even at the liquid-gas interface in a significant number of cases, they do not work for generalized bodies undergoing buoyancy in combination with appreciable body density inhomogeneity, volume change (PIV), or volume rate-of-change (PIV and AFP). In these less common cases, the 3D body shape needs to be measured and resolved in time and space to estimate the unsteady body force. The analysis shows that accounting for the unsteady body force is straightforward to non

    Directory of Open Access Journals (Sweden)

    Hannah M Edwards

    Full Text Available Human population movement across country borders presents a real challenge for malaria control and elimination efforts in Cambodia and its neighbouring countries. To quantify Plasmodium infection among the border-crossing population, including asymptomatic and artemisinin resistant (AR parasites, three official border crossing points, one from each of Cambodia's borders with Thailand, Laos and Vietnam, were selected for sampling.A total of 3206 participants (of 4110 approached were recruited as they crossed the border, tested for malaria and interviewed. By real-time polymerase chain reaction (RT-PCR, 5.4% of all screened individuals were found to harbour Plasmodium parasites. The proportion was highest at the Laos border (11.5%. Overall there were 97 P. vivax (55.7%, 55 P. falciparum (31.6%, two P. malariae (1.1% and 20 mixed infections (11.5%. Of identified infections, only 20% were febrile at the time of screening. Of the 24 P. falciparum samples where a further PCR was possible to assess AR, 15 (62.5% had mutations in the K13 propeller domain gene, all from participants at the Laos border point. Malaria rapid diagnostic test (RDT pLDH/HRP-2 identified a positivity rate of 3.2% overall and sensitivity compared to RT-PCR was very low (43.1%. Main individual risk factors for infection included sex, fever, being a forest-goer, poor knowledge of malaria prevention methods and previous malaria infection. Occupation, day of the week and time of crossing (morning vs. afternoon also appeared to play an important role in predicting positive cases.This study offers a novel approach to identify asymptomatic infections and monitor AR parasite flow among mobile and migrant populations crossing the borders. Similar screening activities are recommended to identify other hot borders and characterise potential hot spots of AR. Targeted "customised" interventions and surveillance activities should be implemented in these sites to accelerate elimination efforts

    2003-01-01

    Presently, HB-Line work at the Savannah River Site consists primarily of the stabilization and packaging of nuclear materials for storage and the characterization of materials for disposition in H-Area. In order to ensure compliance with Material Control and Accountability (MC and A) Regulations, accountability measurements are performed throughout the HB-Line processes. Accountability measurements are used to keep track of the nuclear material inventory by constantly updating the amount of material in the MBAs (Material Balance Area) and sub-MBAs. This is done by subtracting the amount of accountable material that is added to a process and by adding the amount of accountable material that is put back in storage. A Physical Inventory is taken and compared to the ''Book Value'' listed in the Nuclear Material Accounting System. The difference (BPID) in the Book Inventory minus the Physical Inventory of a sub-account for bulk material must agree within the measurement errors combined in quadrature to provide assurance that nuclear material is accounted for. This work provides an overview of HB-Line processes and accountability measurements. The Scrap Recovery Line and Neptunium-237/Plutonium-239 Oxide Line are described and sampling and analyses for Phase II are provided. Recommendations for improvements are provided to improve efficiency and cost effectiveness

    2011-01-01

    A microcontroller (AT89C51) based electronics has been designed and developed for high precision calibrator based on Digiquartz pressure transducer (DQPT) for the measurement of high hydrostatic pressure up to 275 MPa. The input signal from DQPT is converted into a square wave form and multiplied through frequency multiplier circuit over 10 times to input frequency. This input frequency is multiplied by a factor of ten using phased lock loop. Octal buffer is used to store the calculated frequency, which in turn is fed to microcontroller AT89C51 interfaced with a liquid crystal display for the display of frequency as well as corresponding pressure in user friendly units. The electronics developed is interfaced with a computer using RS232 for automatic data acquisition, computation and storage. The data is acquired by programming in Visual Basic 6.0. This system is interfaced with the PC to make it a computer controlled system. The system is capable of measuring the frequency up to 4 MHz with a resolution of 0.01 Hz and the pressure up to 275 MPa with a resolution of 0.001 MPa within measurement uncertainty of 0.025%. The details on the hardware of the pressure measuring system, associated electronics, software and calibration are discussed in this paper.

    In this work, a novel junction profile measurement method is proposed. A serial of junctions were fabricated by B+ implantation. Then a beveled bar which was about 10mm long and several micrometers deep was formed by carefully controlled wet-etching. The remaining depth of n region changes from the full depth that is about 5.3mm after ion implantation to zero depending on its lateral position and the slope of the etching bar. Voltage-current and Laser Beam Induced Current (LBIC) measurements were applied to determine the HgCdTe junction edge. The LBIC signal orrectification characteristic indicates the existence of a PN junction. The junction depth is extracted from the position where the PN junction disappears and the slope of the etching bar. The junction depth of intrinsic doped HgCdTe was measured, which is about 2.4μm. A significant 0.4mm thick N-region was observed. Moreover, junction depths of samples annealed for different time were also investigated. By this method, it's possible to measure the three dimensional profile of a planar PN junction.

  5. Revitalising Borders: Memory, Mobility and Materiality in a Latvian-Russian Border Region

    Directory of Open Access Journals (Sweden)

    Aija Lulle

    2016-04-01

    Full Text Available In this paper I investigate how an international border is 'revitalised' in political discourses as opposed to lived experiences. Based on narratives I have collected from border dwellers on both sides of the current border between Latvia and Rus-sia and placing them into a broader context of current border debates, I analyse how geographical and social mobility is remembered from Soviet times and reworked in current contexts. I argue that while politically the border is revitalised through aban-doning and forgetting the Soviet past and through the idea of constant threats in the future, locally it is revitalised through giving a life to the abandoned: memories of 'vigorous times' in life-courses and material things. People who dwell at the border did not move themselves: the international border moved several times in one cen-tury leaving border dwellers' memories and significant places on the 'other' side. I focus on how these borders were crossed in the past, how they are (not crossed now, and the social meanings assigned to these circumstances. In the current con-text I follow diverse paths of reasoning that describe how the uneven flow of goods and people through the Latvian-Russian border shapes the power dynamic against which the people living in the border area used to reconstruct imaginaries of 'Soviet times' versus 'Europe' and 'vigorous times' versus decline.

    Purpose: Breast density is a significant breast cancer risk factor. Although various methods are used to estimate breast density, there is no standard measurement for this important factor. The authors are developing a breast density standardization method for use in full field digital mammography (FFDM). The approach calibrates for interpatient acquisition technique differences. The calibration produces a normalized breast density pixel value scale. The method relies on first generating a baseline (BL) calibration dataset, which required extensive phantom imaging. Standardizing prospective mammograms with calibration data generated in the past could introduce unanticipated error in the standardized output if the calibration dataset is no longer valid. Methods: Sample points from the BL calibration dataset were imaged approximately biweekly over an extended timeframe. These serial samples were used to evaluate the BL dataset reproducibility and quantify the serial calibration accuracy. The cumulative sum (Cusum) quality control method was used to evaluate the serial sampling. Results: There is considerable drift in the serial sample points from the BL calibration dataset that is x-ray beam dependent. Systematic deviation from the BL dataset caused significant calibration errors. This system drift was not captured with routine system quality control measures. Cusum analysis indicated that the drift is a sign of system wear and eventual x-ray tube failure. Conclusions: The BL calibration dataset must be monitored and periodically updated, when necessary, to account for sustained system variations to maintain the calibration accuracy.

    EPA's Storm Water Management Model (SWMM) is a computational code heavily relied upon by industry for the simulation of wastewater and stormwater infrastructure performance. Many municipalities are relying on SWMM results to design multi-billion-dollar, multi-decade infrastructure upgrades. Since the 1970's, EPA and others have developed five major releases, the most recent ones containing storm control measures modules for green infrastructure. The main objective of this study was to quantify the accuracy with which SWMM v5.1.10 simulates the hydrologic activity of previously monitored low impact developments. Model performance was evaluated with a mathematical comparison of outflow hydrographs and total outflow volumes, using empirical data and a multi-event, multi-objective calibration method. The calibration methodology utilized PEST++ Version 3, a parameter estimation tool, which aided in the selection of unmeasured hydrologic parameters. From the validation study and sensitivity analysis, several model improvements were identified to advance SWMM LID Module performance for permeable pavements, infiltration units and green roofs, and these were performed and reported herein. Overall, it was determined that SWMM can successfully simulate low impact development controls given accurate model confirmation, parameter measurement, and model calibration.

    In California, significant progress has been made to control emissions from industrial sources as well as from motor vehicles. Nonetheless, policy analysts still debate over whether it makes sense to control motor vehicle emissions through legislated reductions in vehicle use, especially when new vehicle emission standards are becoming even more stringent in California. In this paper, the emission reduction benefits of California's new low-emission vehicles and clean fuels program are reviewed. The air quality management plans of three major metropolitan areas in California are examined, to identify emission reductions needed to meet federal and state air quality standards. For each of these three areas, emission reductions expected from transportation control measure implementation are presented. Then, the extent to which the reductions are open-quotes significantclose quotes and relied upon in each of the local attainment efforts is analyzed. The emission reductions expected from the stringent exhaust emission standards of California's new low-emission vehicles and clean fuels program will not be sufficient to meet mandated clean air standards in the study areas. Based upon our review, transportation control measures appear to be necessary components of the air quality management plans in California's major metropolitan areas. The paper concludes that cost-effective transportation control measures (TCMs) will be needed as a complementary strategy to California's stringent tail-pipe standards in moderate to extreme nonattainment areas

    The machine is designed for the automatic measurement of fuel pins after irradiation in the fast reactors and is a modified version of a machine which has been in use for several years. These modifications consist of mechanical improvements and solid state control circuitry but the design criteria are unchanged. Irradiated fuel pins with diameters up to 0.875 in. are measured at fixed axial positions and angular intervals. Axial stepping of either 1 cm or 1 in. with a standard deviation of 5 x 10 -4 in. and angular rotation by multiples of 18 0 with a non-cumulative error of 1 0 can be selected. Data on axial position to 0.1 in. or 0.1 cm and fuel element diameter to 5 x 10 -5 in. are both punched and printed out for computer evaluation. The standard deviation of a single measurement on cylindrical specimens with an eccentricity of up to at least 0.1 in. should be no worse than 1 x 10 -4 in. No operator attention is required after the pin is positioned in the machine and 40 sets of 10 diameter readings at 36 0 intervals can be performed in an hour. Switches can be set between 1 and 99 to terminate an examination when power is switched off with the machine in its rest position. (author)

    Full Text Available Jean-Philippe Baguet1,21Department of Cardiology, University Hospital, 2Bioclinic Radiopharmaceutics Laboratory, INSERM U1039, Joseph Fourier University, Grenoble, FranceAbstract: Hypertension is an important risk factor for the development of cardiovascular disease, and is a major cause of morbidity and mortality worldwide. Traditionally, hypertension diagnosis and treatment and clinical evaluations of antihypertensive efficacy have been based on office blood pressure (BP measurements; however, there is increasing evidence that office measures may provide inadequate or misleading estimates of a patient’s true BP status and level of cardiovascular risk. The introduction, and endorsement by treatment guidelines, of 24-hour ambulatory BP monitoring and self (or home BP monitoring has facilitated more reliable and reproducible estimations of true BP, including the identification of white-coat and masked hypertension, and evaluation of BP variability. In addition, ambulatory BP monitoring enables accurate assessment of treatment effectiveness over 24 hours and both ambulatory and self BP monitoring may lead to better tailoring of therapy according to BP profile and concomitant disease. This review describes the clinical benefits and limitations of out-of-office assessments and their applications for effective management of hypertension and attainment of BP control.Keywords: ambulatory, ABPM, SBPM, blood pressure measurement, hypertension

    Full Text Available Clinical mobility assessment is traditionally performed in laboratories using complex and expensive equipment. The low accessibility to such equipment, combined with the emerging trend to assess mobility in a free-living environment, creates a need for body-worn sensors (e.g., inertial measurement units—IMUs that are capable of measuring the complexity in motor performance using meaningful measurements, such as joint orientation. However, accuracy of joint orientation estimates using IMUs may be affected by environment, the joint tracked, type of motion performed and velocity. This study investigates a quality control (QC process to assess the quality of orientation data based on features extracted from the raw inertial sensors’ signals. Joint orientation (trunk, hip, knee, ankle of twenty participants was acquired by an optical motion capture system and IMUs during a variety of tasks (sit, sit-to-stand transition, walking, turning performed under varying conditions (speed, environment. An artificial neural network was used to classify good and bad sequences of joint orientation with a sensitivity and a specificity above 83%. This study confirms the possibility to perform QC on IMU joint orientation data based on raw signal features. This innovative QC approach may be of particular interest in a big data context, such as for remote-monitoring of patients’ mobility.

    A measurement evaluation program (MEP) is one of a number of valuable tools that analytical chemists can use to ensure that the data produced in the laboratory are fit for their intended purpose and consistent with expected performance values at a given time. As such, participation in a MEP is an important indicator of the quality of analytical data, and is recognized as such by independent regulatory and/or accreditation bodies. With the intent to implement such a program in Brazil, in November 2012 the Nuclear Energy Commission of Brazil (CNEN), with support from the Department of Energy of the United States' (US-DOE International Safeguards and Engagement Program), decided to initiate a technical cooperation project aiming at organizing a Safeguards Measurement Evaluation Program (SMEP) for Brazilian facilities. The project, entitled Action Sheet 23, was formalized under the terms of the Agreement between the US-DOE and the CNEN concerning research and development in nuclear material control, accountancy, verification, physical protection, and advanced containment and surveillance technologies for International Safeguards Applications. The work, jointly performed by the CNEN's Safeguards Laboratory (LASAL) and the New Brunswick Laboratory (NBL), has the objective to strengthen the traceability of accountability measurements and ensure adequate quality of safeguards measurements for facilities within Brazil, utilizing test samples characterized and provided by NBL. Recommendations to participants included measurement frequency, number of results per sample and format for reporting results using ISO methods for calculating and expressing measurement uncertainties. In this paper, we discuss the main steps taken by CNEN and NBL aiming at implementing such a program and the expected results, in particular the impact of uncertainty estimation on the evaluation of performance of each participant laboratory. The program is considered by Brazilian safeguards authorities

    The GRASP nursing workload management system was used over a five-month period by both the infection control nurses (ICNs) in an infection control team (ICT) in a 1200-bedded university teaching hospital trust. GRASP data were used to quantify and qualify patient and Trust requirements for infection control (IC). The results indicated that care was being prioritised as the average daily patient care requirement was 15.9 h, whereas the ICNs were only able to provide 12.7 h to meet this. Infection control nurses spent 5.3 h dealing with methicillin-resistant Staphylococcus aureus (MRSA), and only 3.9 h in preparation and delivery of education. A 'fire brigade service' was being provided at the expense of developmental and strategic issues. GRASP provided a method of quantifying, recording and analysing workload. It was used to support recommendations from the Health Quality Service Organizational Audit (Kings Fund), the Department of Health (DoH), the National Audit Office (NAO), and the Health and Safety Executive (HSE) for an increased focus on education and risk management in IC. It was also used in a skill-mix exercise, and resulted in the appointment of additional staffing to the ICT. GRASP data could be used for benchmarking with other institutions to provide a flexible system which may be adapted to meet the changing demands of the health service. It provides a means for ICNs to measure and manage their workload, and may be adapted to other members of the ICT. Copyright 2001 The Hospital Infection Society.

    2008-01-01

    The Department of Homeland Security National Cyber Security Division supported development of a small set of security ideals as a framework to establish measurable control systems security. Based on these ideals, a draft set of proposed technical metrics was developed to allow control systems owner-operators to track improvements or degradations in their individual control systems security posture. The technical metrics development effort included review and evaluation of over thirty metrics-related documents. On the bases of complexity, ambiguity, or misleading and distorting effects the metrics identified during the reviews were determined to be weaker than necessary to aid defense against the myriad threats posed by cyber-terrorism to human safety, as well as to economic prosperity. Using the results of our metrics review and the set of security ideals as a starting point for metrics development, we identified thirteen potential technical metrics - with at least one metric supporting each ideal. Two case study applications of the ideals and thirteen metrics to control systems were then performed to establish potential difficulties in applying both the ideals and the metrics. The case studies resulted in no changes to the ideals, and only a few deletions and refinements to the thirteen potential metrics. This led to a final proposed set of ten core technical metrics. To further validate the security ideals, the modifications made to the original thirteen potential metrics, and the final proposed set of ten core metrics, seven separate control systems security assessments performed over the past three years were reviewed for findings and recommended mitigations. These findings and mitigations were then mapped to the security ideals and metrics to assess gaps in their coverage. The mappings indicated that there are no gaps in the security ideals and that the ten core technical metrics provide significant coverage of standard security issues with 87% coverage. Based

    This occasional paper identifies applicable cooperative monitoring techniques and develops models for possible application in the context of the border between China and India. The 1993 and 1996 Sino-Indian agreements on maintaining peace and tranquility along the Line of Actual Control (LAC) and establishing certain confidence building measures (CBMs), including force reductions and limitation on military exercises along their common border, are used to examine the application of technically based cooperative monitoring in both strengthening the existing terms of the agreements and also enhancing trust. The paper also aims to further the understanding of how and under what conditions technology-based tools can assist in implementing existing agreements on arms control and confidence building. The authors explore how cooperative monitoring techniques can facilitate effective implementation of arms control agreements and CBMS between states and contribute to greater security and stability in bilateral, regional, and global contexts.

    Most arms-control-treaty-monitoring scenarios involve a host party that makes a declaration regarding its nuclear material or items and a monitoring party that verifies that declaration. A verification system developed for such a use needs to be trusted by both parties. The first concern, primarily from the host party's point of view, is that any sensitive information that is collected must be protected without interfering in the efficient operation of the facility being monitored. This concern is addressed in what can be termed a 'certification' process. The second concern, of particular interest to the monitoring party, is that it must be possible to confirm the veracity of both the measurement system and the data produced by this measurement system. The monitoring party addresses these issues during an 'authentication' process. Addressing either one of these concerns independently is relatively straightforward. However, it is more difficult to simultaneously satisfy host party certification concerns and monitoring party authentication concerns. Typically, both parties will want the final access to the measurement system. We will describe an alternative approach that allows both parties to gain confidence simultaneously. This approach starts with (1) joint development of the measurement system followed by (2) host certification of several copies of the system and (3) random selection by the inspecting party of one copy to be use during the monitoring visit and one (or more) copy(s) to be returned to the inspecting party's facilities for (4) further hardware authentication; any remaining copies are stored under joint seal for use as spares. Following this process, the parties will jointly (5) perform functional testing on the selected measurement system and then (6) use this system during the monitoring visit. Steps (1) and (2) assure the host party as to the certification of whichever system is eventually used in the monitoring visit

  4. From “Customary” to “Illegal”: Yao Ethnic Marriages on the Sino-Vietnamese Border

    Elena Barabantseva

    2015-06-01

    Full Text Available This article examines changing governing practices in the context of the Sino-Vietnamese border in the Guangxi Autonomous Region of China. The groups inhabiting the mountainous ranges of this ethnically diverse part of Southeast Asia evaded the reach of the state until the 1970s, when China and Vietnam started tightening control over the land border after the border war. With an increasingly rigid and clearly delimited Sino-Vietnamese borderland, binary forms of classification began to replace earlier fluid identifications, and the room for diverse social and cultural expressions became restricted. It is within this context that the ethnic marriage practices straddling the borders of China and its southern neighboring states discussed in this article took place. Cross-border ethnic Yao marriages have gone from customary to illegal in recent years as a result of China’s strict population control, its changing demography, and the accelerated shortage of manual labor in its border area. Border politics have permeated the private sphere, transforming common ethnic marriage partners into illegal migrants. Although ethnic marriage partners are relegated to an illegal status, they are indispensible in the local labor market and moral economy as mothers, caretakers, translators, guides, and manual workers. This article argues that, despite being antithetical to the bordering logic of state sovereignty, they are important agents who depend on and capitalize on the border economy.

    ITER in-vessel components such as blankets and divertors are categorized as scheduled maintenance components because they are subjected to severe plasma heat and particle loads. Blanket maintenance requires remote handling equipment and tools able to handle Heavy payloads of about 4 tons within a 2 mm precision tolerance. Divertor maintenance requires remote replacement of 60 cassettes with a dead weight of about 25 tons each. In the ITER R and D program, full-scale remote handling equipment for blanket and divertor maintenance has been designed and assembled for demonstration tests. This paper reviews the measurement and control system developed for full-scale remote handling equipment, the Japan Home Team contribution. (author)

  6. Languaging the Borders of Europe

    Full Text Available Emerging from a discomfort with the blind spots encountered within and across theorizations of language and space in the field of human geography, in this article, we argue for “making space” for conceptualizations that speak from and through the everyday territories of migrants in Europe today. Inspired by a range of writers thinking postcolonially and multi/trans-lingually, the authors draw on their own embodied migrant experience to argue for re-envisioning Europe’s borders through multiple languaging practices. “Languaging”, in this view, takes linguistic practices in a migrant context as an inherently prosthetic activity, whereby any dominant, national host language is inevitably subject to the subterranean rumblings of all the languages a migrant brings with her on her global journeys. Conceived as being saturated with prosthetic “absence(s”, migrant languaging practices rework cultural geography’s bounded, inward-looking, and security-fixated understanding of the language/territory nexus, the better to open a vital space for re-envisioning language’s everyday territories as sites for translational solidarity and becoming.

    Full Text Available “Borders, boundaries and desirable wishes” is the title of the residential workshop offered to a group of young adults (aged 18-25 of the Centro di Salute Mentale (Mental Health Center of the DSM Basaglia of ASL TO2 in Turin. The idea of the workshop, the definition of the objectives and the topics, which are clearly expressed in the title, come from the work of the team dedicated to group psychotherapies, which has been offering group psychodrama sessions to young adults of this age since 2008. In the delicate move to the adult age, these young adults are lost and stuck in static realities where it is not possible to open up to the dimension of desire nor to the transforming encounter with the Other, since they didn’t have the experience of boundaries and lack. These two elements are necessary to acquire the ability to make projects for oneself. During the workshop the following instruments were used: group, psychodrama and art therapy. The group, as a paternal function, ensured the presence of safe boundaries enabling individuals to experiment; psychodrama and art therapy enabled the bodies to experience encounters and transformations, using doing as a metaphor for the movement against the inhibition of doing and as a way to show oneself to the Other and be able to see the Other. 

  8. Semantic Borders and Incomplete Understanding.

    Science.gov (United States)

    Silva-Filho, Waldomiro J; Dazzani, Maria Virgínia

    2016-03-01

    In this article, we explore a fundamental issue of Cultural Psychology, that is our "capacity to make meaning", by investigating a thesis from contemporary philosophical semantics, namely, that there is a decisive relationship between language and rationality. Many philosophers think that for a person to be described as a rational agent he must understand the semantic content and meaning of the words he uses to express his intentional mental states, e.g., his beliefs and thoughts. Our argument seeks to investigate the thesis developed by Tyler Burge, according to which our mastery or understanding of the semantic content of the terms which form our beliefs and thoughts is an "incomplete understanding". To do this, we discuss, on the one hand, the general lines of anti-individualism or semantic externalism and, on the other, criticisms of the Burgean notion of incomplete understanding - one radical and the other moderate. We defend our understanding that the content of our beliefs must be described in the light of the limits and natural contingencies of our cognitive capacities and the normative nature of our rationality. At heart, anti-individualism leads us to think about the fact that we are social creatures, living in contingent situations, with important, but limited, cognitive capacities, and that we receive the main, and most important, portion of our knowledge simply from what others tell us. Finally, we conclude that this discussion may contribute to the current debate about the notion of borders.

The motivation behind the approach lies in the fact that scientific collaboration...... in border regions, in general, and the studied region, in particular, has rarely been discussed in the academic literature. The integration model of cross-border regional innovation systems provides the conceptual framework for the task. The paper, thus, gives methodological insights for the measurement...

    Lan, Jun

    In the era of economic globalization, strengthen of international cooperation on network education is a general trend. Although China has not made commitments about the market access and national treatment of cross-border supply in Schedule of Specific Commitments on Services, the basic conditions of network education development in China have been met. The Chinese government should formulate strategies for the development of cross-border network education and take relevant measures to implement them. In the near future, the carrying out of cross-border network education in China will become an irreversible trend, and will possess broad prospect with the advance of globalization of Chinese education.

    The concentration of nuclear power plants in border areas raises the problem of protection of the population and the environment in border lands. The author recalls the fundamental legal principle according to which no country may cause a prejudice to a neighbouring country due to installations harmful to the environment which are located in its own territory. Several legal systems are reviewed which provide for participation by neighbouring states in nuclear plant projects and licensing; the recourse procedure against such plants is also discussed. Finally, consideration is given to problems to be solved in order to coordinate legal and administrative measures in case of construction of nuclear plants in border areas. (NEA) [fr

    Full Text Available OBJECTIVES This study examines recently revised Korean government legislation addressing global infectious disease control for public health emergency situations, with the aim of proposing more rational, effective and realistic interpretations and applications for improvement of law. METHODS The Korea reported its first laboratory-confirmed case of Middle East Respiratory Syndrome (MERS coronavirus on May 20, 2015. Since the first indexed case, Korean public health authorities enforced many public health measures that were not authorized in the law; the scope of the current law was too limited to cover MERS. Korea has three levels of government: the central government, special self-governing provinces, and si/gun/gu. Unfortunately, the Infectious Disease Control and Prevention Act does not designate the specific roles of each level of government, and does not state how these governmental branches should be vertically integrated in a state of emergency. RESULTS When thinking about these policy questions, we should be especially concerned about introducing a new act that deals with all matters relevant to emerging infectious diseases. The aim would be to develop a structure that specifies the roles of each level of government, and facilitates the close collaboration among them, then enacting this in law for the prevention and response of infectious disease. CONCLUSIONS To address this problem, after analyzing the national healthcare infrastructure along with the characteristics of emerging infectious diseases, we propose the revision of the relevant law(s in terms of governance aspects, emergency medical countermeasure aspects, and the human rights aspect.

    To determine the frequency of application of prevention and control measures for type 2 diabetes in Mexican population. ENSANUT 2012 is a nationally and by-state representative survey. Sample design was probabilistic, multistage, stratified and clustered. The information of 46 277 adults≥20 was used for this analysis. A weighted analysis was performed using Stata 12. Prevalence of diabetes by previous diagnosis was 9.2% (6.4 millions) in ENSANUT 2012, 7.3% (3.7 millions) in 2006 and 4.6% (2.1 millions) in 2000. In 2012, the mean of medical examinations in the previous year related to diabetes control was 7.3. However, the percentage of cases in which preventive actions for chronic complications were performed (such as foot care [14.6%], ophthalmology [8.6%] and determination of HbA1c [9.6%]) was low. Patients with diabetes have frequent access to medical services. However, preventive actions are applied insufficiently both in quality and quantity.

    1985-01-01

    The Defense Waste Processing Facility (DWPF) for immobilizing Savannah River Plant (SRP) high-level radioactive waste is now under construction. Previously stored waste is retrieved and processed into a glass matrix for permanent storage. The equipment operates in an entirely remote environment for both processing and maintenance due to the highly radioactive nature of the waste. A fine powdered glass frit is mixed with the waste prior to its introduction as a slurry into an electric glass furnace. The slurry is Bingham plastic in nature and of high viscosity. This combination of factors has created significant problems in flow measurement and control. Specialized pieces of equipment have been demonstrated that will function properly in a highly abrasive environment while receiving no maintenance during their lifetime. Included are flow meters, flow control technology, flow switching, and remote connections. No plastics or elastomers are allowed in contact with fluids and all electronic components are mounted remotely. Both two- and three-way valves are used. Maintenance is by crane replacement of process sections, utilizing specialized connectors. All portions of the above are now operating full scale (radioactively cold) at the test facility at SRP. 4 references, 8 figures

    This article reflects on European borders and their everyday dynamics from a cross-border perspective. The article begins with a discussion of recent events that question current border policies in the European Union, reviews the literature on borders and border territories, and finally moves on to a discussion of the everyday effects of cross-border practices on the inhabitants of border spaces. Occasional reference is made to borders in the Americas to complete the picture of this topic. Although the issue of security is indeed relevant, we focus on the economic and social dimensions of cooperation. Three aspects are essential for border residents who attempt to use the advantages of the territories for their global nature: work, shopping, and place of residence. In conclusion, there has been a tendency toward the softening of borders and greater integration of border zones in the European Union.

Since then, the disease has increased its incidence and geographical distribution. In the 2006-2012 period, 107 human cases were detected (11 deaths. The presence of Lutzomyia longipalpis was detected in peridomiciles in Puerto Iguazú urban area in 2010; some of these findings were associated with households where cases of canine VL had already been reported. The objective of this study was to ascertain the abundance and spatial distribution of Lu. longipalpis in Puerto Iguazú City, on the Argentina-Brazil-Paraguay border. Lu. longipalpis proved to be exclusively urban and was found in 31% of the households sampled (n = 53, 67% of which belonged to areas of low abundance, 20% to areas of moderate abundance and 13% to areas of high abundance. Nyssomyia whitmani was the only species found both in urban and peri-urban environments, and Migonemyia migonei was registered only on the outskirts of the city. Due to the fact that Puerto Iguazú is considered to be at moderate risk at the moment, it is necessary to intensify human and canine case controls, as well as take integrated prevention and control measures regarding the environment, vectors and reservoirs on the Argentina-Brazil-Paraguay border area.

    The emissions of zinc along roads originating from tyre wear, corrosion of safety fence and other traffic-related sources have been quantified and validated by measured long-term loads in road run-off and airborne solids (drift) for 29 published case studies. The distribution pattern over the road border at various distances from the edge of the paved surface is assessed on the basis of 38 published case studies with measured concentrations in soil. For the impact assessment, the road border is differentiated into a zone that is part of the 'technosphere' and the 'target zone' beyond that technosphere that can be considered as part of the receiving environment. The 'technosphere' of the road includes the central reservation, the hard and the soft shoulder or, if one or both shoulders are not present, the so-called obstacle 'free zone' that is defined by road engineers. Pollution within the technosphere may require appropriate management of solid disposal and isolation from groundwater to prevent further distribution of pollutants to the environment. In the target zone along regional roads, the zinc load is about 4 mg/m{sup 2} year and this is of the same order of magnitude as that of atmospheric deposition in areas beyond the influence of roads (background). In the target zone along highways, the zinc load is increased in comparison to the background deposition. The average load of about 38 mg/m{sup 2} year is similar to that in fertilised agricultural land. Because most of the emitted zinc stays in the technosphere, the total amount entering this target zone along highways is limited. From the 140 tons of zinc per year that is released from tyre wear in The Netherlands, 64 tons is emitted in the urban area, 6.5 tons reaches to the target zones of all roads and only 1.1 tons of zinc will enter the target zone along highways. This amount will be further decreased by the application of porous asphalt in the near future. The

    Full Text Available International borders greatly influence tourism development. In 2012 and 2013, a decline in tourists to Zimbabwe from South Africa was partially attributed to tourist border facilitation issues. It is against this background that this study sought to establish the nature of challenges faced by tourists when using the Beitbridge border post (Zimbabwean side. Questionnaire responses were thematically analysed and the study concluded that border administrative management related issues are a major barrier to tourism. Key among the study's recommendations is that the depressed tourists' border experiences obtaining at Beitbridge border post among other constraints have to be addressed as a matter of urgency. This will enhance Zimbabwe's accessibility, tourist satisfaction and the image of the country as a destination. The paper further identifies several destination managerial implications and future research priorities.

    Full Text Available Discourse theory is useful for understanding the creation of borders, whether material or imaginary. This paper addresses three situations on Mexico’s southern border between 2000 and 2015 in which elements of discourse theory may be applied. The outcomes were the following: 1 correlations may be made between the elements of the discourse moving from the northern to the southern border, but not in the opposite direction; 2 the process of securitising the discourse about migrants is continuous, and new securitising elements are regularly added; 3 an “elastic borders” phenomenon exists, where borders extend or retract, thereby creating new border regions; and 4 discourses around the southern border are constructed with more pejorative elements than the northern, despite the fact that crime rates are higher in the north.

Some conservatives also endorse libertarian principles of legitimacy. It is not clear though that this sort of defence of closed borders is somehow coherent with these libertarian ideals. I argue that conservative libertarians of this kind must reject this defence of closed borders because either it collapses into a form of statism incoherent with libertarian principles of legitimacy, or into an ideal precept without appeal regarding reality in the here and now that could only be applied to changing the very nature of the societies we know. As a result, at least conservative libertarians need to find a different source of justification for closed borders.

    2000-01-01

    As compared to electron storage rings, one advantage of recirculating linear accelerators is that the beam properties at target are no longer dominated by the equilibrium between quantum radiative diffusion and radiation damping because new beam is continually injected into the accelerator. This allows the energy spread from a CEBAF-type machine to be relatively small; the measured energy spread from CEBAF at 4 GeV is less than 100 parts per million accumulated over times of order several days. In this paper, the various subsystems contributing to the energy spread of a CEBAF-type accelerator are reviewed, as well as the machine diagnostics and controls that are used in CEBAF to ensure that a small energy spread is provided during routine running. Examples of relevant developments are (1) stable short bunches emerging from the injector, (2) precision timing and phasing of the linacs with respect to the centroid of the beam bunches on all passes, (3) implementing 2 kHz sampling rate feedback systems for final ...

    1999-01-01

    The paper describes the design and preliminary results of an extended pilot study of commercially available monitoring systems for the detection of nuclear and other radioactive materials at borders. The study consists of a laboratory test phase and field tests at the Austrian/Hungarian border and the Vienna airport, each for a duration of one year. The results will be used to derive realistic performance requirements for border control systems in view of optimized technical and economic conditions as well as to propose an 'investigation level'. The ITRAP study consists of three phases. In the first phase equipment currently available on the market is subjected to laboratory testing at the Austrian Research Centres Seibersdorf. The instrument categories include hand-held, portable, and fixed-installed equipment. The test criteria defined as minimum requirements have been established together with the manufacturers. The laboratory tests started in May 1998 and will last until end of this year. During the second phase, the field study, equipment passing the laboratory tests will be installed at a major Austrian-Hungarian border crossing (Nickelsdorf) for monitoring of cars, trucks and trains, as well as at the Vienna airport for pedestrians, luggage and cargo. In this phase the results gained from the lab tests about the 'fitness for use' will be verified in practice, in close co-operation with the law enforcement officers at the borders. Also training issues and questions of maintenance and support shall be evaluated. In the third phase, realistic specifications and performance requirements shall be derived with the help of international experts and selected specialists from the users and manufacturers. The results of the field study will focus not only on the technical aspects of monitoring equipment (e.g. detection threshold and rate of false alarms) but also on the operational (e.g. ease of use, reliability, training requirements, field support) and economic

    Full Text Available There are hundreds of departments and organizations working on border health issues in the California/Baja California border region trying to protect and improve health without a collaborative structure that integrates jurisdictions and organizations. As a result, there is a need to effectively improve the health in the border region by coordinating these organizations to work together and benefit from each other’s best practices. The newly developed California Border Health Collaborative (CBHC can provide the leadership and collaborative culture to positively improve the health of the border region. This article aims to describe the development process of this collaborative to include key ingredients to success, the roles of mulit-level jurisdictions, and policy implications.This article describes the methods used to develop key aspects of collaborative leadership, strategic alignment and a common vision toward the building of this collective impact approach to border health.

    Stella Regina Martins

    Full Text Available ABSTRACT Objective: To determine the level of agreement with effective tobacco control measures recommended by the World Health Organization and to assess the attitudes toward, knowledge of, and beliefs regarding smoking among third-year medical students at University of São Paulo School of Medicine, located in the city of São Paulo, Brazil. Methods: Between 2008 and 2012, all third-year medical students were invited to complete a self-administered questionnaire based on the Global Health Professionals Student Survey and its additional modules. Results: The study sample comprised 556 students. The level of agreement with the World Health Organization recommendations was high, except for the components “received smoking cessation training” and “raising taxes is effective to reduce the prevalence of smoking”. Most of the students reported that they agree with banning tobacco product sales to minors (95%, believe that physicians are role models to their patients (84%, and believe that they should advise their patients to quit cigarette smoking (96% and using other tobacco products (94%. Regarding smoking cessation methods, most of the students were found to know more about nicotine replacement therapy than about non-nicotine therapies (93% vs. 53%. Only 37% of the respondents were aware of the importance of educational antismoking materials, and only 31% reported that they believe in the effectiveness of encouraging their patients, during medical visits. In our sample, the prevalence of current cigarette smoking was 5.23%; however, 43.82% of the respondents reported having experimented with water-pipe tobacco smoking. Conclusions: Our results revealed the need to emphasize to third-year medical students the importance of raising the prices of and taxes on tobacco products. We also need to make students aware of the dangers of experimenting with tobacco products other than cigarettes, particularly water-pipe tobacco smoking.

  1. On the control of irrigation through soil moisture measurement using a neutron depth probe in horizontal subsurface measuring circuits

    An outline is given of the advantages inherent in soil moisture measurement by means of a neutron probe in horizontal subsurface measuring circuits for irrigation control. Preliminary experience for the setting up of a field calibration curve and for practical measurement are submitted. This technique includes the following advantages: almost complete covering of the upper soil range which is of interest to irrigation control; good measuring density; suitable distribution of measuring points per unit area; possibility of continuous probe passage; optimal repeatability of measurements; exploration of a unit area with but few measuring circuits; no obstacles to tillage, drilling, intercultivation and harvest operations; and complete conservation of crop and plot which is not reached with any other soil moisture measurement technique so far available. Making use of the above advantages, the new technique allows automatic irrigation control with only one neutron depth probe. (author)

    Baseline entomological surveys were conducted in four sentinel sites along the Thailand-Myanmar border to address vector bionomics and malaria transmission in the context of a study on malaria elimination. Adult Anopheles mosquitoes were collected using human-landing catch and cow-bait collection in four villages during the rainy season from May-June, 2013. Mosquitoes were identified to species level by morphological characters and by AS-PCR. Sporozoite indexes were determined on head/thoraces of primary and secondary malaria vectors using real-time PCR. A total of 4,301 anopheles belonging to 12 anopheline taxa were identified. Anopheles minimus represented >98% of the Minimus Complex members (n=1,683), whereas the An. maculatus group was composed of two dominant species, An. sawadwongporni and An. maculatus. Overall, 25 Plasmodium-positive mosquitoes (of 2,323) were found, representing a sporozoite index of 1.1% [95%CI 0.66-1.50]. The transmission intensity as measured by the EIR strongly varied according to the village (ANOVA, F=17.67, df=3, PThailand-Myanmar border that represent a formidable challenge for malaria control and elimination. © 2017 The Society for Vector Ecology.

  4. Cross-border mobility and social networks: Laotians seeking medical treatment along the Thai border.

    2015-01-01

    Drawing upon research conducted on cross-border patients living in Laos and seeking care in Thailand, this paper examines the important role played by social networks in patients' decision-making and on the itineraries they choose to seek treatment on the Thai side of the border. Due to the vastly contrasting situations between the two countries in terms of healthcare supply, and considering Laotians' increasing demand for high quality healthcare, a number of them have managed to satisfy their needs by combining cross-border treatment with the use of the healthcare facilities provided by their own country. This study consisted first of household surveys conducted in five border areas (2006-2007) in Laos in order to quantify and map out cross-border healthcare-related travel patterns. Afterwards, interviews were conducted with cross-border patients (55), Laotian and Thai medical doctors (6), Thai social workers (5), and officials working in public institutions (12). While socioeconomic and spatial factors partly explain cross-border mobility, patients' social networks significantly influence treatment itineraries throughout the decision-making process, including logistical and financial considerations. The social networks existing at different geographical levels (neighbourhood, regional and global) are therefore a powerful analytical tool not only for understanding the emergence of these cross-border movements but also for justifying them in an authoritarian political environment such as Lao PDR's.

  5. Border regions as the tourist destination

    Directory of Open Access Journals (Sweden)

    Majstorović Vukica

    2013-01-01

    Full Text Available Tourism, as a global phenomenon, has found its place in every corner of the world. During a certain period of time, the tourism market has become saturated by mass tourism causing the creation of new attractive destinations for tourists. Thus, some of the border areas in the world attract and keep passers-by while transforming into the new tourist destinations. In this paper, it is possible to see relations and interconnections between tourism and international boundaries. Tourism in border regions has an opportunity to activate these areas that are often neglected by the state. Some European countries have taken advantage of this opportunity and they improved their tourism industry by developing their border regions. This kind of tourism development can be applied in Serbia and, in that way, activate the border areas of our country. However, in order to develop tourism in these areas, it is necessary to have an adequate international cooperation between two or more states. This can be achieved by various instruments of cross-border cooperation in tourism through the engagement of neighbouring countries in joint plans and cooperation.

  6. Quantum Zeno Effects from Measurement Controlled Qubit-Bath Interactions

    Science.gov (United States)

    Harrington, P. M.; Monroe, J. T.; Murch, K. W.

    2017-06-01

    The Zeno and anti-Zeno effects are features of measurement-driven quantum evolution where frequent measurement inhibits or accelerates the decay of a quantum state. Either type of evolution can emerge depending on the system-environment interaction and measurement method. In this experiment, we use a superconducting qubit to map out both types of Zeno effect in the presence of structured noise baths and variable measurement rates. We observe both the suppression and acceleration of qubit decay as repeated measurements are used to modulate the qubit spectrum causing the qubit to sample different portions of the bath. We compare the Zeno effects arising from dispersive energy measurements and purely dephasing "quasimeasurements," showing energy measurements are not necessary to accelerate or suppress the decay process.

  8. Analysis of mechanical-hydraulic bedload deposition control measures

    Science.gov (United States)

    Schwindt, S.; Franca, M. J.; De Cesare, G.; Schleiss, A. J.

    2017-10-01

    During floods, the bedload transport of steep headwaters can exceed the hydraulic transport capacity of milder downstream reaches where settlements are often situated. Therefore, sediment retention barriers are typically installed upstream of such sensible areas. These barriers trigger bedload trapping via two control mechanisms, either hydraulic or mechanical. Both deposition controls, pertaining to instream sediment trapping structures, are analyzed experimentally in this study. Bedload trapping by hydraulically controlled barriers is prone to sediment flushing, i.e., the remobilization of formerly deposited sediment, in particular when the barrier is simultaneously under- and overflown. In this case, the remobilization rate is close to the bedload transport capacity of the nonconstricted channel. Mechanical deposition control by screens is in turn sensible to the grain size. Thus, both deposition control concepts may fail, and bedload may be transported downstream at a rate corresponding to the transport capacity of headwaters, thereby endangering urban areas. This study shows that the combination of both deposition control concepts is suitable for improving the control of bedload retention. With this combination, undesired sediment flushing of upstream deposits in the channel caused by insufficient hydraulic control is prevented. Furthermore, the uncertainty related to the estimation of the representative grain size in the design of mechanical control barriers is reduced.

  15. Power control of water reactors using nitrogen 16 activity measurements

    International Nuclear Information System (INIS)

    1964-01-01

    At the Grenoble Nuclear Research Centre, the open-core swimming pool reactors Melusine (2 MW) and Siloe (15 MW) are controlled at a constant overall power using nitrogen-16 channels. The conventional linear control channels react instantaneously to the rapid power fluctuations, this being necessary for the safety of the reactors, but their power indications are erroneous since they are affected by local deformations of the thermal flux caused by the compensation movements of the control rods. The nitrogen-16 channels on the other hand give an indication of the overall power proportional to the mean fission flux and independent of the rod movements, but their response time is 15 seconds, A constant overall power control is thus possible by a slow correction of the reference signal given by the automatic control governed by thu linear channels by means of a correction term given by the 'N-16' channels: This is done automatically in Melusine and manually in Siloe.

  17. Interpretation of the source-specific substantive control measures of the Minamata Convention on Mercury.

    Science.gov (United States)

    You, Mingqing

    2015-02-01

    Being persistent, toxic, and bio-accumulative, Mercury (Hg) seriously affects the environment and human health. Due to Hg's attribute of long-range environmental transport across national borders, especially through atmospheric transport, no country can fully protect its environment and human health with its own efforts, without global cooperation. The Minamata Convention on Mercury, which was formally adopted and opened for signature in October 2013, is the only global environmental regime on the control of Hg pollution. Its main substantive control measures are source-specific: its phasing-out, phasing-down, and other main substantive requirements all direct to specific categories of pollution sources through the regulation of specific sectors of the economy and social life. This Convention does not take a national quota approach to quantify the Parties' nationwide total allowable consumption or discharge of Hg or Hg compounds, nor does it quantify their nationwide total reduction requirements. This paper attempts to find the underlying reasons for this source-specific approach and offers two interpretations. One possible interpretation is that Hg might be a non-threshold pollutant, i.e., a pollutant without a risk-free value of concentration. The existence of a reference dose (RfD), reference concentration (RfC), provisional tolerable weekly intake (PTWI), minimal risk level (MRL) or other similar reference values of Hg does not necessarily mean that Hg cannot be regarded as non-threshold because such reference values have scientific uncertainties and may also involve policy considerations. Another interpretation is that Hg lacks a feasibly determinable total allowable quantity. There is evidence that negotiators might have treated Hg as non-threshold, or at least accepted that Hg lacks a feasibly determinable total allowable quantity: (1) The negotiators were informed about the serious situations of the current emissions, releases, and legacy deposition; (2

  19. TACTICS OF BORDER CROSSING MOVEMENT: EXPLORING THE MOBILITY OF BRAZILIANS THROUGH THE SCHENGEN AND UK AIRSPACE

    Directory of Open Access Journals (Sweden)

    Gustavo Dias

    2015-08-01

    Full Text Available This paper addresses the relations between migrants, mobility, tactics, negotiation, and the contemporary definition of borders in the aftermath of 9/11.The empirical focus of this paper is how Brazilians from Alto Paranaiba journey through airports located in the Schengen area and in the British territory to London. As a main research orientation, I use the notion of journey as approached by mobility studies, where actions and skills remain an important link between the wayfarer and the social space in which s/he moves through, the embodied practice to how we grasp the world. Migrants deal and struggle against border regime, but they are not powerless social actors. They rather produce creative resistance to reinvent their journey through the surveillance apparatus, which manage and delimit places with targets and threats. In this process, I explore the notion of border crossing movement as a tactical mobility developed by migrants to overcome the border control imposed by governments in airports. The article was drawn through fieldwork conducted initially in London, between 2009 and 2013, and afterwards in Alto Paranaiba, during 2013. The ethnographic study consisted in semi-structured interviews, participant observation through snowball technique, which enabled me to access a considerable number of participants in these two regions explored. The argument that I develop is that migrants as social actors are part important in the dialogue produced between border crossing and border reinforcement.

  20. Economic integration and cross-border economic organizations: The case of San Diego-Tijuana

    Jorge Eduardo Mendoza Cota

    2017-01-01

    Full Text Available The economic integration between the United States and Mexico has affected the economic, political and social relations in the border region. The paper seeks to relate the increasing economic integration and business cycles of the economies of San Diego and Tijuana to the development of both national and binational economic organizations in the border region. The methodology of analysis uses both statistical estimations of the economic integration of San Diego and Tijuana and semi-structured interviews of economic organizations to analyze the increasing economic integration and the role and achievements of the cross-border economic organizations. The results showed that cross-border cooperation is predominately controlled by federal and state governments on both sides of the border. However, the main achievements of cross-border economic cooperation have been accomplished by local private organizations. The perspective of further local economic development greatly depends on both the possibility of increased involvement of federal governments and the growing encouragement of regional organizations.

    A few months after the signature of the agreement giving the go-ahead for the expansion of CERN into French territory (see Bulletin no.24/2004), work began on the Super Proton Synchrotron (SPS). Two years later, on 31 July 1974, the Robbins tunnel-boring machine excavating the SPS tunnel returned to its starting point (see photograph). It had excavated a tunnel with a circumference of 7 kilometres, at an average depth of 40 metres below the surface. The tunnel straddled the Franco-Swiss border, making the SPS the first cross-border accelerator. More than a thousand magnets were needed to equip the ring. The civil engineering and installation work was completed in record time after only four years. The SPS was equipped with a control system which was ahead of its time, consisting of 24 small control computers distributed in the tunnel and the control room and communicating by means of a high-rate data transmission system. The main control room housed only four consoles as opposed to the banks of electronic ...

  11. Crossing the Borders: An Eco-cinecritical Analysis of Plant Wars and Bird Without Borders

    Hsiao-Ching Li

    2011-01-01

    Full Text Available This essay reads two Asian nature-oriented films from the perspective of ecocinecriticism,an ecologically minded film criticism. Plant Wars, produced by PTSTaiwan, questions the demarcation between native plants and exotic plants as well asbetween plants and human beings so as to remap the in-between border area. Thestorytelling method it applies is to feature 14 currently native plants as the maincharacters, and illustrates their relationship to aboriginal people, farmers, beekeepersand to other insect species. Bird Without Borders, also produced by PTS, tells the storyof the migration journey of a group of black-faced spoonbills flying 16,000 kilometersall the way from Tainan, Taiwan, to Japan, along the border of South and North Korea,to a remote island of China to look for feeding places and then back to Taiwan to spendthe winter. Different layers of border-crossing are shown in Bird. One similarity ofthese two PTS productions is the search for border-crossing so as to redefine or revisewhat the border means. Plant questions the biological categorization of the native plantsand the exotic plants; Bird illustrates how the crew physically follows the route of thebirds’ flight which crosses the national borders to provide a vision of remapping thenatural territory through challenging the idea of a fixed “place.” Both are seeking forways to trespass the man-made borders: Plant via environmental imagination; Bird viasome physical movement. While the title of Plant Wars seemingly expresses its positionmore strongly through “wars,” Bird Without Borders explicitly asserts a dream of noborders.

    This paper examines alcohol-related social problems among Mexican Americans living along the U.S.-Mexico border and in non-border areas. Interviews were conducted among Mexican Americans in the border regions of California, Arizona, New Mexico, and Texas (N=1307). Non-border respondents were interviewed primarily in Houston and Los Angeles (N=1288) as part of the Hispanic Americans Baseline Alcohol Survey (HABLAS). Both the border and HABLAS surveys employed multistage cluster sample designs (response rates were 67% and 76%, respectively). In the bivariate analysis, there were no significant differences between border and non-border areas in the proportion of those with one or more social problem. In non-border areas, the prevalence of alcohol problems did not differ significantly by age. However, along the border the prevalence of alcohol problems was significantly different across age groups, with 18 to 29year old men and women having the highest prevalence. The final models showed no residence effect on problem likelihood. Drinking was strongly associated with problems. Although young border residents had higher problem prevalence rates than older residents, the logistic regression models showed no effect of border residence on the likelihood of problems, indicating that problems are due to alcohol consumption, not the border environment. The border, however, did appear to influence more drinking among young people. Regardless of residence, alcohol treatment and preventive interventions tailored to Mexican Americans are essential and special attention should be focused on younger individuals near the border.

    2017-08-01

    This paper concerns the issues of construction and experimental tests of a temperature stabilization system for small resistance increments measurement circuits. After switching the system on, a PCB board heats up and the long-term temperature drift altered the measurement result. The aim of this work is reducing the time of achieving constant nominal temperature by the measurement system, which would enable decreasing the time of measurements in the steady state. Moreover, the influence of temperatures higher than the nominal on the measurement results and the obtained heating curve were tested. During the working process, the circuit heats up to about 32 °C spontaneously, and it has the time to reach steady state of about 1200 s. Implementing a USART terminal on the PC and an NI USB-6341 data acquisition card makes recording the data (concerning temperature and resistance) in the digital form and its further processing easier. It also enables changing the quantity of the regulator settings. This paper presents sample results of measurements for several temperature values and the characteristics of the temperature and resistance changes in time as well as their comparison with the output values. The object identification is accomplished due to the Ziegler-Nichols method. The algorithm of determining the step characteristics parameters and examples of computations of the regulator settings are included together with example characteristics of the object regulation.

    2015-01-01

    This paper provides an overview of the diagnostics implemented on WEST and gives more details on the infra-red system which is one of the main systems used to analyze the heat loads and ensure the machine protection. The modification of the CODAC and communications networks is also discussed. The new functionalities and architecture of the WEST PCS are detailed; especially it ensures the orchestration of many subsystems such as diagnostics, actuators and allows handling asynchronous off-normal events during the plasma discharge. In correlation the plasma discharge is now seen as a set of elementary pieces (called segments) joints together. Development of new plasma controllers will be addressed. An overview of the first wall monitoring activity and development is provided. Finally preparing the plasma restart requires control oriented modelling and simulations devoted to the control of the plasma shape will be presented

    2005-01-01

    Utilization of cement as building material is gaining more importance. Cement industries around the world are contributing in global and as well as local pollution. In Pakistan most of the cement industries are constructed in remote areas without any proper environmental impact assessment. Unawareness of peoples toward sustainable environment and due to lack of job opportunities, dwellers are demanding employment rather than clean environment from title-holder of the industry. Air pollution caused by cement industries is harmful to the human's health, spoils and erodes building surface, corrodes metals, weakens textiles, deteriorates atmospheric visibility, affects plant life and leads to ecological imbalances. To investigate environmental impact of cement industries in Pakistan, environmental conditions around and inside the five cement industries in the vicinity of Taxila city are studied. To inspect the whole scenario, air pollution control devices in these industries were also examined in detail. These industries are using Electrostatic Precipitators and Baghouses to control air pollution (dust particulates). Proper caring of these equipment is necessary for better results. Detailed study shows that emissions from their stacks and dust particulates are causing problems. Health consultants in study area are much worry about the health of workers and environmental degradation in the vicinity of these industries. The comparison of air pollution control devices shows that Baghouses are environmental friendly. Considering the field conditions it is also concluded that involvement of government and environmental pollution control agencies is much more necessary. (author)

This paper discusses the history of copper leaching, the need for solution mining development, and solution mining process descriptions. It discusses measurement requirements for deposit evaluation and the injection and production wellfields. It is concluded with a listing of desirable but unavailable instrumentation for further development of this technology

  16. Mathematical Modelling of Bacterial Meningitis Transmission Dynamics with Control Measures

    Directory of Open Access Journals (Sweden)

    Joshua Kiddy K. Asamoah

    2018-01-01

    Full Text Available Vaccination and treatment are the most effective ways of controlling the transmission of most infectious diseases. While vaccination helps susceptible individuals to build either a long-term immunity or short-term immunity, treatment reduces the number of disease-induced deaths and the number of infectious individuals in a community/nation. In this paper, a nonlinear deterministic model with time-dependent controls has been proposed to describe the dynamics of bacterial meningitis in a population. The model is shown to exhibit a unique globally asymptotically stable disease-free equilibrium E0, when the effective reproduction number RVT≤1, and a globally asymptotically stable endemic equilibrium E1, when RVT>1; and it exhibits a transcritical bifurcation at RVT=1. Carriers have been shown (by Tornado plot to have a higher chance of spreading the infection than those with clinical symptoms who will sometimes be bound to bed during the acute phase of the infection. In order to find the best strategy for minimizing the number of carriers and ill individuals and the cost of control implementation, an optimal control problem is set up by defining a Lagrangian function L to be minimized subject to the proposed model. Numerical simulation of the optimal problem demonstrates that the best strategy to control bacterial meningitis is to combine vaccination with other interventions (such as treatment and public health education. Additionally, this research suggests that stakeholders should press hard for the production of existing/new vaccines and antibiotics and their disbursement to areas that are most affected by bacterial meningitis, especially Sub-Saharan Africa; furthermore, individuals who live in communities where the environment is relatively warm (hot/moisture are advised to go for vaccination against bacterial meningitis.

  17. Control device intended for a gamma radiation measuring instrument

    International Nuclear Information System (INIS)

    1976-01-01

    This invention concerns a monitoring device for a gamma radiation measuring instrument or radiation meter, in which the radiation to be measured brings about, inter alia, the ionisation of a gas and the generation of current pulses. The dial of this meter is generally calibrated in roentgens per hour, i.e. in radiation rate units. This instrument of very simple design is remarkable for its operating reliability. Preferably placed at the inlet to a radioactive area, it enables every user of a ratemeter to check, over the entire measuring range of this instrument, its proper operation prior to entering the area. To this effect, the monitoring device in question has a thick wall lead castle, having an internal cavity in which is mounted a radioactive source delivering a gamma radiation with given constant characteristics, through a measurement window closed by a calibrated plug. Lead doors articulated on the castle can be superimposed on this window to bring about a given attenuation of the radiation coming from the source and delivered to the exterior of the castle [fr

  3. Challenges in reducing dengue burden; diagnostics, control measures and vaccines.

    Science.gov (United States)

    2013-09-01

    Dengue is a major public health concern worldwide, with the number of infections increasing globally. The illness imposes the greatest economic and human burden on developing countries that have limited resources to deal with the scale of the problem. No cure for dengue exists; treatment is limited to rehydration therapy, and with vector control strategies proving to be relatively ineffective, a vaccine is an urgent priority. Despite the numerous challenges encountered in the development of a dengue vaccine, several vaccine candidates have shown promise in clinical development and it is believed that a vaccination program would be at least as cost-effective as current vector control programs. The lead candidate vaccine is a tetravalent, live attenuated, recombinant vaccine, which is currently in Phase III clinical trials. Vaccine introduction is a complex process that requires consideration and is discussed here. This review discusses the epidemiology, burden and pathogenesis of dengue, as well as the vaccine candidates currently in clinical development.

    An examination is conducted of the Skyship 500's dynamic response to control inputs from elevators, rudders, and throttles at zero, 25, and 40 kts indicated airspeed. Input frequency sweeps were made with pitch and turn controls at 25 and 40 kts, ranging in frequency from about 0.03 to 1.5 Hz. FFT data analysis was then applied to compute describing functions for each run. Frequency responses are noted to be very smooth, and comparisons between repeat runs indicate excellent agreement. Summary plots of the faired describing functions from each run form the core of the data presented. These data constitute a comprehensive and reliable data base on which to predicate future dynamic simulation mathematical models of small airship dynamic response.

  6. Environmental insecticide residues from tsetse fly control measures in Uganda

    International Nuclear Information System (INIS)

    Sserunjoji-Sebalija, J.

    1976-01-01

    Up to June 1974 areas in Uganda totalling 8600km 2 have been successfully reclaimed from tsetse fly infestation by ground spray of 3% dieldrin water emulsions. A search for equally effective but less persistent and toxic compounds against tsetse flies has been unsuccessful. Fourteen insecticide formulations have been tested for their persistence on tree bark surfaces and, therefore, their availability and toxicity to the target tsetse flies. Only those compounds with a high immediate insecticidal activity (some higher than dieldrin) like endosulfan, Chlorfenvinphos and propoxur could merit further consideration in tsetse control. While some were toxic to tsetse as fresh deposits, they lacked sufficient persistence. A study of the environmental implication from the continued use of the highly persistent and toxic dieldrin has provided useful data on residues likely to be found both in terrestrial and aquatic fauna and flora. These are generally low. Moreover, there is evidence of degradation in some fish species (Protopterus aethiopicus and Clarias). Also, dilution factors and adsorption involving the muddy nature of water run-off, etc., and controlled burning of grasses after tsetse eradication would tend to inactivate the residual insecticide and protect aquatic systems. The general findings have indicated less risk than anticipated of the environmental contamination from tsetse control by application of persistent and toxic insecticides. (author)

  12. Improved FPGA controlled artificial vascular system for plethysmographic measurements

    Directory of Open Access Journals (Sweden)

    Laqua Daniel

    2016-09-01

    Full Text Available The fetal oxygen saturation is an important parameter to determine the health status of a fetus, which is until now mostly acquired invasively. The transabdominal, fetal pulse oximetry is a promising approach to measure this non-invasively and continuously. The fetal pulse curve has to be extracted from the mixed signal of mother and fetus to determine its oxygen saturation. For this purpose efficient algorithms are necessary, which have to be evaluated under constant and reproducable test conditions. This paper presents the improved version of a phantom which can generate artificial pulse waves in a synthetic tissue phantom. The tissue phantom consists of several layers that mimic the different optical properties of the fetal and maternal tissue layers. Additionally an artificial vascular system and a dome, which mimics the bending of the belly of a pregnant woman, are incorporated. To obtain data on the pulse waves, several measurement methods are included, to help understand the behavior of the signals gained from the pulse waves. Besides pressure sensors and a transmissive method we integrated a capacitive approach, that makes use of the so called “Pin Oscillator” method. Apart from the enhancements in the tissue phantom and the measurements, we also improved the used blood substitute, which reproduces the different absorption characteristics of fetal and maternal blood. The results show that the phantom can generate pulse waves similar to the natural ones. Furthermore, the phantom represents a reference that can be used to evaluate the algorithms for transabdominal, fetal pulse oximetry.

  13. Porosity Measurements and Analysis for Metal Additive Manufacturing Process Control.

    Science.gov (United States)

    Slotwinski, John A; Garboczi, Edward J; Hebenstreit, Keith M

    2014-01-01

    Additive manufacturing techniques can produce complex, high-value metal parts, with potential applications as critical metal components such as those found in aerospace engines and as customized biomedical implants. Material porosity in these parts is undesirable for aerospace parts - since porosity could lead to premature failure - and desirable for some biomedical implants - since surface-breaking pores allows for better integration with biological tissue. Changes in a part's porosity during an additive manufacturing build may also be an indication of an undesired change in the build process. Here, we present efforts to develop an ultrasonic sensor for monitoring changes in the porosity in metal parts during fabrication on a metal powder bed fusion system. The development of well-characterized reference samples, measurements of the porosity of these samples with multiple techniques, and correlation of ultrasonic measurements with the degree of porosity are presented. A proposed sensor design, measurement strategy, and future experimental plans on a metal powder bed fusion system are also presented.

    2004-12-01

    This work presents the development of a streak camera 'jitter free' sweep unit synchronized on a femtosecond laser. This application of high voltage photoconductive switches ('High voltage Auston switch') yields subpicosecond resolution for accumulated images on streak camera on a few hundreds micro joule femtosecond laser. Two others applications of these photoconductive switches are studied: - ultrafast optical commutation by a Pockels cell directly driven by a photoconductive switch (rising edge < 100 ps and jitter < 2 ps), - laser pulse energy self-stabilization experimentally proving that driving a Pockels cell by a photoconductive switch can increase the stability of the laser pulse energy from 7 % to 0.7 % rms. Additionally, the application of the acoustic-optical programmable dispersive filter (Dazzler) to the self referenced spectral phase measurement is presented. As these measurements require a linear filter combined with a non linear filter, it is possible to replace the complete linear part (generally a complex optical set-up) by the Dazzler leading to new kind of linear filters and new measurements. Thus base band autocorrelation and time-domain SPIDER (SPIDER by Fourier transform spectroscopy) have been demonstrated experimentally for the first time. (author)

  15. Hmong Across Borders or Borders Across Hmong? Social and Political Influences Upon Hmong People

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward. However, even within the context of Southeast Asia and southern China, the Hmong are a transnational ethnic group, due to state boundaries and the enforcement of international laws.Scholars speak as though the Hmong population has crossed political and legal borders by their movement across state boundaries and international borders. However, I argue that it is the political, social, and legal borders that have cut across the Hmong people and subjected them to be citizens of different modern nation-states. Even in the present time, these borders still, and continuously, play important roles that cross and divide the Hmong people into distinctive subgroups and fragments. In this article, I will start by describing the generally understood situation of Hmong being across national borders, and then will explain my argument that borders are across the Hmong.

    Air pollution in large cities is still a matter of concern. Especially the concentration of fine particles (PM10 and PM2.5) is largest in large cities leading to severe health impacts. Furthermore the PM10 thresholds of the EU Air Quality Directive are frequently exceeded. Thus the question arises, whether the initiated policies and measures for mitigating air pollution are sufficient to meet the air quality targets and - if not - which efficient further pollution mitigation measures exist. These questions have been addressed in the EU research project MEGAPOLI for the four European megacities respectively agglomerations London, Paris, Rhine-Ruhr area and Po valley. Firstly, a reference scenario of future activities and emissions has been compiled for the megacities for the years 2020, 2030 and 2050 for all relevant air pollutants (CO, NH3, NMVOC, NOx, PM10, PM2.5 and SO2) and greenhouse gases (CO2, CH4 and N2O). The reference scenario takes into account as well population changes as technical progress and economic growth. As pollution flowing in from outside the city is about as important as pollution caused by emissions in the city, the analysis covers the whole of Europe and not only the city area. Emissions are then transformed into concentrations using atmospheric models. The higher concentrations in cities were estimated with a newly developed 'urban increment' model. Results show, that in the megacities the limits of the Air Quality Directive (2008/50/EC) will be exceeded. Thus additional efforts are necessary to reduce emissions further. Thus, a number of further measures (not implemented in current legislation) were selected and assessed. These included mitigation options for road transport, other mobile sources, large combustion plants, small and medium combustion plants and industry. For each measure and in addition for various bundles of measures a cost-benefit analysis has been carried out. Benefits (avoided health risks and climate change risks) have

  20. An Institutional Approach to Bordering in Islands: The Canary Islands on the African-European Migration Routes

    2012-05-01

    Full Text Available Islands play a significant role in international irregular maritime migration. Frequently they are part of maritime interstitial spaces between states, and their location, combined with institutional membership, makes them part of international migration routes and subject to border management strategies. In this paper borders are analysed as social institutions used for regulating relative permeability through rules of entry and exit for persons, goods and capital. Borders institutionalize territoriality and are politically implemented by states. They are selective, also in migration, and irregular border transit is not always indicative of an inability to control. The Canary Islands are used as an illustrative example of how border management at the southern edge of the European Union has evolved towards more coercive deterrence and tighter surveillance. The Canary Islands experienced irregular maritime immigration from the west African coasts during the first decade of the 21st century and most of these migrants intended to use the islands as transit space towards the European continent. Increasing surveillance in countries of origin, enforcement of border controls and stricter return policies were used to stop flows. The so-called “cayuco crisis” in 2006 induced institutional change in border management and forced the active involvement of the EU through FRONTEX.

    2002-01-01

    Fuel processing systems for low temperature polymer electrolyte membrane (PEM) fuel cell systems require control of the carbon monoxide concentration to less than 100 ppm to 10 ppm in the anode feed. Conventional hydrocarbon fuel processors use a water-gas shift (WGS) reactor to react CO with water to form H2 and reduce the CO concentration. The CO conversion is limited by equilibrium at the outlet temperature of the WGS reactor. The WGS outlet CO concentration can range from over 1% to 2000 ppm depending on the system and its operating parameters. At these concentrations, CO poisons low temperature PEM fuel cells and the concentrations needs to be reduced further.

    2015-12-01

    Full Text Available In recent years, the border shared by Peru, Colombia and Brazil has become an enclave of drug production and trafficking for the international markets. It is a territory whose control is disputed by non-state actors and where state security forces suffer from severe material and transport limitations. This paper takes an ethnographic approach to explain the limitations of border security and the institutional challenges of controlling drug and wood trafficking in this context. It places the ideas of reproduction and social change at the centre of the discussion on drugs and borders, as key ways of thinking about the dynamics of growing and processing coca-derived drugs in the global South.

    Tai Chi for Arthritis (TCA) is recognized by the CDC as an evidenced-based program to prevent falls in older adults. Although seated Tai Chi is recommended for those unable to stand, little is known about balance control during seated TCA. To explore the use of posturography to assess differences between experts and non-expert practitioners of seated TCA. Twenty-three participants were recruited from those attending a Tai cChi workshop. While seated in a hard back chair centered on a force platform, participants performed selected forms from TCA and then did them in a continuous sequence. Center of pressure (CoP) indices to assess balance were normalized by height and then compared between expert and non-expert participants. Experts had significantly greater average velocity and path length (p = 0.02) for the entire sequence and open/close, but not for CoP 95% Confidence ellipse area. No significant differences in the CoP were found for commencement, wave hands, or single whip. A few differences in balance control while performing seated TCA movements were found. Future studies are needed to determine whether these can be accounted for by quality of the Tai Chi movements or factors associated with the seated position.

    2003-10-01

    The recording and reproducing capabilities of a Yamaha Disklavier grand piano and a Bösendorfer SE290 computer-controlled grand piano were tested, with the goal of examining their reliability for performance research. An experimental setup consisting of accelerometers and a calibrated microphone was used to capture key and hammer movements, as well as the acoustic signal. Five selected keys were played by pianists with two types of touch (``staccato'' and ``legato''). Timing and dynamic differences between the original performance, the corresponding MIDI file recorded by the computer-controlled pianos, and its reproduction were analyzed. The two devices performed quite differently with respect to timing and dynamic accuracy. The Disklavier's onset capturing was slightly more precise (+/-10 ms) than its reproduction (-20 to +30 ms); the Bösendorfer performed generally better, but its timing accuracy was slightly less precise for recording (-10 to 3 ms) than for reproduction (+/-2 ms). Both devices exhibited a systematic (linear) error in recording over time. In the dynamic dimension, the Bösendorfer showed higher consistency over the whole dynamic range, while the Disklavier performed well only in a wide middle range. Neither device was able to capture or reproduce different types of touch.

    1998-11-01

    As a result of major political and societal changes in the past several years, methods of nuclear material control may no longer be as effective as in the past in Russia, the Newly Independent States (NIS), and the Baltic States (BS). The objective of the Department of Energy (DOE) Material Protection, Control, and Accounting Program (MPC and A) is to reduce the threat of nuclear proliferation by collaborating with Russia, NIS, and BS governments to promote western-style MPC and A. This cooperation will improve the MPC and A on all weapons useable nuclear materials and will establish a sustainable infrastructure to provide future support and maintenance for these technology-based improvements. Nuclear materials of proliferation concern include materials of the types and quantities that can be most easily and directly used in a nuclear weapon. Sabotage of nuclear material is an event of great concern and potentially disastrous consequences to both the US and the host country. However, sabotage is currently beyond the scope of program direction and cannot be used to justify US-funded MPC and A upgrades. Judicious MPC and A upgrades designed to protect against insider and outsider theft scenarios would also provide addition, although not comprehensive, protection against saboteurs. This paper provides some suggestions to establish consistency in prioritizing system-enhancement efforts at nuclear material facilities. The suggestions in this paper are consistent with DOE policy and directions and should be used as a supplement to any policy directives issued by NN-40, DOE Russia/NIS Task Force.

    Full Text Available Background. The evolution from quadrupedalism to bipedalism has adjusted the balance of the upper limb to extensive movement at the shoulder. The scapular angles provide the point of attachment and control to various muscles and have been associated with the different movements of the shoulder girdle and joint. This has made the morphometric and anthropometric study of scapula a subject of extensive investigation. Aim. In the present study, the angle at the medial border was measured in the South-Southern Nigerian population and an anatomical name was ascribed to the angle. Method. The study was conducted on 173 scapulae (75 right and 98 left obtained from various Anatomy Department of South-Sothern Nigerian Universities. The angle at medial border was obtained by pinning the edge of the superior and inferior angles, the lined traced out, and the angle measured using a protractor. SPSS version 20 was used to analyse the data. t-test was used to determine mean angular difference in the sides. Result. The mean ± SD of the medial angle was observed to be 136.88 ± 7.70° (R = 138.13 ± 7.06° : L = 135.92 ± 8.05°. Statistical analysis using the Z-test for mean difference showed the medial angle was found to be higher in the right side of the scapula (mean difference of 2.214 ± 1.152°, but the observed difference was not statistically significant (P > 0.05. The above findings have adjusted the scapula from three to four angles (lateral, superior, inferior, and medial formed from four borders (lateral, superior, inferior, and superomedial and inferomedial. The medial angle because of its anatomical location was named “spinovertebral” angle, owing to its position at the scapulae spine, and located in medial proximity to the vertebra column. Conclusion. The medial angle (now referred to as the spinovertebral angle of the right side of the scapula is wider than the left. The representation of the spinovertebral angle is very important, as

    The result of the magnetic measurements after the cold mass assembly is a holding point for the production of the LHC main dipoles. Here we describe how the magnetic measurements are screened to validate them and to work out faulty components or assembly procedures. The control limits are based on the experience acquired on the first 13 measured cold masses, and comparison to collared coil magnetic measurements. These limits are applied to 58 cold masses to carry out the quality control. The strategy used to set control limits and the main results of the quality control are discussed.

  6. The Nature and Functions of European Political Borders

    Full Text Available The political border limits a state’s territory and symbolizes the extent of a state’s power and ownership. Borders give integrity to the inner state territory which they enclose (the role of establishing national integrity and at the same time form an outer boundary segregating the state territory from the surrounding politicial entities (the segregation role. European borders are old and reflect the political history of an old continent. The last major border changes happened after World War II. Over the centuries borders were merely lines separating one territory from another. Such borders were understood as »frontiers«. Forming an effective barrier against enemies was the overriding function of borders. Many borders were fortified and further enhanced by means of various defensive systems. In the second half of the 20th century the character of political borders changed. They became a contact area between countries, nations and cultures. Contemporary European borders reflect the colourful history of an old continent. They are predominantely functional markers: they represent the political and juridical delimitation of territories, they mark economic barriers and show their defensive nature and reveal the extent of cultural contact. As a result of European integration processes, the nature of political borders has changed: instead of division, their integration role is brought to the fore. A united Europe is nevertheless still not a borderless Europe! The borders within the »Schengen-area« have retained their political and administrative functions, it is just that the customs and security checks at the borders have been removed. During the period of European integration, borderlines were stabilized in accordance with the 1974 Helsinki Agreement. But despite this we can still observe ongoing changes to state borders, particularly in areas of conflict such as the Balkan peninsula. It seems after all that the process of demarcation

  7. Opportunities for Cross-Border Entrepreneurship Development in a Cluster Model Exemplified by the Polish–Czech Border Region

    Directory of Open Access Journals (Sweden)

    Joanna Kurowska-Pysz

    2016-03-01

    Full Text Available The subject of the paper is the analysis and evaluation of cross-border entrepreneurship development opportunities on the basis of cross-border cooperation, which has gradually evolved from consisting of bilateral partnerships to a networking model or even a cluster. The study conducted at the Polish–Czech border area indicates that, in terms of the development of cross-border cooperation, the economic sphere is lagging far behind social activities such as culture, education and tourism. At the same time, Polish and Czech enterprises are not sufficiently mobilized to develop cross-border entrepreneurship, although a number of support instruments in this regard have been proposed. Sustainable development of the border should take into account both social and economic aspects. An important research problem therefore becomes determining the possibility of boosting the development of cross-border entrepreneurship on the basis of the existing forms of cross-border cooperation, including cooperation in the social sphere. The aim of this paper is to define the conditions and opportunities for the development of cluster cooperation in the area of cross-border entrepreneurship. The author has attempted to resolve whether the intensity of cross-border cooperation can be a factor which mobilizes companies to develop their cross-border entrepreneurship and whether cross-border entrepreneurship can be further developed within the cluster model.

  8. Traceability and quality control in mammography: measurements and models

    International Nuclear Information System (INIS)

    Peixoto, Jose Guilherme Pereira

    2002-10-01

    The success of a treatment or diagnosis using radiation, depends on the optimization of the dose determination to be administered for the patient and on the beam radiation quality. It is recognized by the international guidelines that it is necessary to improve calibration services for mammography beams in order to improve the quality of clinical diagnosis. Major efforts have been made by several laboratories in order to establish an appropriate and traceable calibration infrastructure and to provide the basis for a quality control program in mammography. The contribution of the radiation metrology network to the mammography services is reviewed in this work. Steps required for the implementation of a mammography calibration system using a constant potential x-ray and a clinical mammography x-ray machine are presented. The various qualities of mammography radiation discussed in this work are in accordance with the IEC 61674 and the AAPM recommendations. This work also presents the methodology and the procedures to maintain and to disseminate the traceability at the x-ray mammography range, describing the interlaboratory comparison performed at LNMRI/IRD/CNEN and at the IPEN/CNEN using the secondary standard ionization chambers traceable with the international standard. It assesses the inter-laboratory comparison consistency and decides whether a questionable value should or not be accepted, using the residual method. This thesis discusses the uncertainties involved in all steps of the calibration chain in accord once with the ISO recommendations. (author)

    This article presents a method for measuring the geometry of crane rails with terrestrial laser scanning (TLS). Two sets of crane rails were divided into segments, their planes were adjusted, and the characteristic rail lines were defined. We used their profiles to define the positional and altitude deviations of the rails, the span and height difference between the two rails, and we also verified that they complied with the Eurocode 3 standard. We tested the method on crane rails at the hydroelectric power plant in Krško and the thermal power plant in Brestanica. We used two scanning techniques: "pure" TLS (Riegel VZ-400) and "hybrid" TLS (Leica MS50) scanning. This article's original contribution lies in the detailed presentation of the computations used to define the characteristic lines of the rails without using the numeric procedures from existing software packages. We also analysed the influence of segment length and point density on the rail geometry results, and compared the two laser scanning techniques. We also compared the results obtained by terrestrial laser scanning with the results obtained from the classic polar method, which served as a reference point for its precision.

    A two-year old, male entire Border collie was presented with a one-year history of exercise-induced collapsing on the pelvic limbs. Physical examination revealed generalised muscle atrophy. Neurological examination supported a generalised neuromuscular disorder. Electromyography revealed spontaneous electrical activity in almost all muscles. Unfixed and formaldehyde-fixed biopsy samples were collected from the triceps brachii, longissimus and vastus lateralis muscles. Histopathological, histochemical and ultrastructural examinations of biopsy specimens were consistent with either centronuclear or myotubular myopathy. The dog clinically improved with supportive treatment with L-carnitine, co-enzyme Q10 and vitamin B compound. To the authors' knowledge, this is the first report of centronuclear/myotubular myopathy in a Border collie. © 2012 British Small Animal Veterinary Association.

    During 2014, Denmark received nearly 15,000 asylum seekers, almost twice the number from the previous year as more people fleeing Syria’s war fled to Europe. By 2016, Denmark succeeded in making the country highly unattractive as a destination for refugees fleeing war torn countries. The country...... introduced a controversial “jewellery bill”, placed adverts in a newspaper in Lebanon dissuading refugees from contemplating a trip to Denmark, and cut assistance benefits for refugees by half. These state bordering practices aimed at securing some kind of “Danishness”. This article aims at ascribing agency...... to young Syrian refugees in Denmark who have experienced these bordering practices and who seek to counter these practices by participating in meaningful social interactions with their Danish counterparts. The empirical focus is an artistic enactment – a weeklong dance workshop that brought...

    Neuronal ceroid lipofuscinosis (NCL) constitutes a group of recessively inherited lysosomal storage diseases that primarily affect neuronal cells. Such diseases share certain clinical and pathologic features in human beings and animals. Neuronal ceroid lipofuscinosis in Border Collie dogs was first detected in Australia in the 1980s, and the pathogenic mutation was shown to be a nonsense mutation (c.619C>T) in exon 4 in canine CLN5 gene. In the present study, novel rapid genotyping assays including polymerase chain reaction (PCR)-restriction fragment length polymorphism, PCR primer-induced restriction analysis, mutagenically separated PCR, and real-time PCR with TaqMan minor groove binder probes, were developed. The utility of microchip electrophoresis was also evaluated. Furthermore, a genotyping survey was carried out in a population of Border Collies in Japan using these assays to determine the current allele frequency in Japan, providing information to control and prevent this disease in the next stage. All assays developed in the current study are available to discriminate these genotypes, and microchip electrophoresis showed a timesaving advantage over agarose gel electrophoresis. Of all assays, real-time PCR was the most suitable for large-scale examination because of its high throughput. The genotyping survey demonstrated that the carrier frequency was 8.1%. This finding suggested that the mutant allele frequency of NCL in Border Collies is high enough in Japan that measures to control and prevent the disease would be warranted. The genotyping assays developed in the present study could contribute to the prevention of NCL in Border Collies.

    Border interactions have reached unprecedented levels in recent decades, not only due to their potential for territorial integration but also considering their role in supranational processes, such as landscape reclamation, infrastructure development and land use planning on European territory. In this scenario, successful examples related to the redevelopment of degraded areas have been showing positive impacts at several levels, such as the social, economic, environmental and aesthetic ones which have ultimately related this process, positively, to sustainability issues. However, concerning to border areas, and due to their inherent legislative and bureaucratic conflicts, the intervention in these areas is more complex. Still, and taking into account previously developed projects and strategies of cross-border cooperation (CBC) in European territory it is possible to identified that the definition of common master plans and common objectives are critical issues to achieve the desired territorial success. Additionally, recent studies have put forward some noteworthy ideas highlighting that it is possible to establish a positive correlation between CBC processes and an increasing redevelopment of degraded border areas, with special focus on the reclamation of derelict landscapes fostering soil reuse and redevelopment. The present research, throughout case study analysis at the Mediterranean level - considering case studies from Portugal, Spain, Monaco and Italy - which presents specific data on border landscape redevelopment, enables us to conclude that CBC processes have a positive influence on the potential redevelopment of degraded border areas, considering not only urban but also rural land. Furthermore, this paper presents data obtained through a public participation process which highlights that these areas present a greater potential for landscape reclamation, fostering resource sustainability and sustainable growth.

    The inherent limitation in performance of building envelop components and heating ventilating and air conditioning (HVAC) equipment necessitates the examination of operational strategies for improvement in energy-efficient operation of buildings. Due to the ease of installation and increasing availability of electronic controllers, operational strategies that could be programmed are of particular interest. The Iowa Energy Center in the US has taken the initiative to conduct the necessary assessment of current HVAC technology and the commonly-used operational strategies for commercial and industrial buildings, as applied to the midwestern part of the country, with weather and energy cost data for Des Moines, Iowa. The first part of this study focused on the energy consumption and cost effectiveness of HVAC systems. The objectives of the second part is concerned with examination of various operational strategies, namely, night purge (NP), fan optimum start and stop (OSS), condenser water reset (CWR), and chilled water reset (CHWR) applied to order and newer-type commercial office buildings. The indoor air quality requirement are met and the latest applicable energy rates from local utility companies are used. The results show that, in general, NP is not an effective strategy in buildings with low thermal mass storage, OSS reduced fan energy, and CWR and CHWR could be effective and require chillers with multi-stage unloading characteristics. The most operationally efficient strategies are the combination of OSS, CWR, and CHWR for the older-type building, and OSS for the newer-type building. Economically, the most effective is the OSS strategy for the older-type building and the CHWR strategy for the newer-type building.(Author)

    Five Border Collie dogs with ceroid-lipofuscinosis developed progressive neurological disease between 18 and 22 months of age. These dogs had behavioural abnormalities, gait and visual deficits and became progressively demented. All dogs examined had common ancestors. Light microscopic examination of tissues demonstrated extensive accumulation of granular, sudan black-staining autofluorescent material in the cytoplasm of neurones, retinal ganglion cells and some visceral cells. At ultrastructural examination inclusions of variable morphology were observed.

    We develop a North-South model of foreign aid and cross-border pollution resulting from production activities in the recipient country. There is both private and public abatement of pollution, the latter being financed through emissions tax revenue and foreign aid. We characterise a Nash equilibrium where the donor country chooses the amount of aid, and the recipient chooses the fraction of aid allocated to pollution abatement and/or the emission tax rate. At this equilibrium, an increase in ...
