  1. A quantitative risk assessment model to evaluate effective border control measures for rabies prevention

    Weng, Hsin-Yi; Wu, Pei-I; Yang, Ping-Cheng; Tsai, Yi-Lun; Chang, Chao-Chin


    Border control is the primary method to prevent rabies emergence. This study developed a quantitative risk model incorporating stochastic processes to evaluate whether border control measures could efficiently prevent rabies introduction through importation of cats and dogs using Taiwan as an example. Both legal importation and illegal smuggling were investigated. The impacts of reduced quarantine and/or waiting period on the risk of rabies introduction were also evaluated. The results showed...

  2. Developing Effective Border Control

    Great progress that has been made in nuclear security measures for counter-proliferation capacity building for effective border controls. However, there is evidence that illicit transfers of military and dual-use items as well as the illicit trafficking of nuclear and other radioactive materials persist. Consequently, there remains an urgent need for continuing and enhancing effective border controls responsive to this threat. Developing and sustaining effective border controls for global defence to combat nuclear security threats is a complex challenge. Following a defence-in-depth approach, border control measures at official ports of entry and green and blue borders form one layer of a national nuclear detection architecture. It is important that the border control measures are both fully integrated into a comprehensive national strategy with achievable nuclear security program objectives and fully sustainable within the national infrastructure. The operations, maintenance and management of effective border control measures rely on a cyclic process of establishing objectives, design, implementation, training and evaluation. All relevant authorities and competencies engage in the process. The design is based on a full assessment of the nuclear security capabilities and associated infrastructure within the context of specific objectives within the national nuclear security strategy. A poor design or badly executed implementation can prevent the effective operation of the system in the short and long run. International cooperation and assistance play an important role in all aspects of developing effective border controls. Donor-recipient relations provide not only the requisite funds, but also the experience and technical expertise that promote effective and sustainable border controls. As the global detection architecture matures, many international organizations, such as International Atomic Energy Agency (IAEA), DOE, European Commission- Joint Research Centre

  3. A quantitative risk assessment model to evaluate effective border control measures for rabies prevention.

    Weng, Hsin-Yi; Wu, Pei-I; Yang, Ping-Cheng; Tsai, Yi-Lun; Chang, Chao-Chin


    Border control is the primary method to prevent rabies emergence. This study developed a quantitative risk model incorporating stochastic processes to evaluate whether border control measures could efficiently prevent rabies introduction through importation of cats and dogs using Taiwan as an example. Both legal importation and illegal smuggling were investigated. The impacts of reduced quarantine and/or waiting period on the risk of rabies introduction were also evaluated. The results showed that Taiwan's current animal importation policy could effectively prevent rabies introduction through legal importation of cats and dogs. The median risk of a rabid animal to penetrate current border control measures and enter Taiwan was 5.33 x 10(-8) (95th percentile: 3.20 x 10(-7)). However, illegal smuggling may pose Taiwan to the great risk of rabies emergence. Reduction of quarantine and/or waiting period would affect the risk differently, depending on the applied assumptions, such as increased vaccination coverage, enforced custom checking, and/or change in number of legal importations. Although the changes in the estimated risk under the assumed alternatives were not substantial except for completely abolishing quarantine, the consequences of rabies introduction may yet be considered to be significant in a rabies-free area. Therefore, a comprehensive benefit-cost analysis needs to be conducted before recommending these alternative measures. PMID:19822125

  4. Internal Border Controls in the European Union

    Jørgensen, Carsten Willemoes; Sørensen, Karsten Engsig


    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...

  5. Strengthening border control and management

    The world has experienced monumental changes in recent years. Globalization has brought many benefits. Business and commerce have increased and, as a result, brought us cheaper, more accessible goods from all regions of the world. We have access to relatively cheap and certainly much easier travel. We now live in a world of instant communications with mobile phones, laptops and 'BlackBerries'. However, there is a downside to globalization - transnationally organized crime and the reality of terrorism have grown. As more people cross borders, it is harder to detect criminals and terrorists. In the European Union, the internal borders of the now 27 member States have been dismantled. Effective international measures to counter organized crime and terrorist groups are of crucial importance. It is important to think globally and to act locally. The paper looks at some of the crime challenges and provides insight into the role and work of the United Nations Office on Drugs and Crime (UNODC) in drugs and crime control. It focuses on border control initiatives conducted by the UNODC. (author)

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


    The French authorities have informed CERN that, in view of the upcoming COP21 Paris Climate Conference, France will exceptionally reintroduce controls at its borders with Schengen states for one month from 13 November to 13 December 2015. All border posts and crossing points between France and Switzerland will be affected by this measure.   Members of the personnel are therefore reminded that, when crossing borders within the Schengen Area*, they must carry: either, in the case of citizens of European Economic Area (EEA) countries and Switzerland, an official identity document (identity card or passport); or, in the case of non-EEA and non-Swiss citizens, an identity document together with a Schengen visa if they are subject to this obligation, or an identity document together with a residence permit issued by a Schengen state** if they have one.   The French authorities will make every effort to limit the impact of this measure on cross-border traffic, and wish to thank the members of th...

  7. Usability in Public Services and Border Control

    Pirelli, Giuliano

    The paper starts with a brief overview of the scale of disability and associated challenges and puts them in the context of the public policy on disability. It then analyses the usability challenges in public services and border control, including the issues of accessibility, safety and communication. These need to be addressed in future policy proposals, to provide the best assistance by new technologies to elderly people and people with disabilities, avoiding creating new barriers due to incorrect or incomplete initial conception. With increasing flux of novel security technology in mass transportation systems, and particularly the use of biometric identification in airports, the challenge of usability is recognized. This paper analyses these issues in the context of users with disability in an idealized process of Simplifying Passenger Travel (SPT).

  8. Nuclear security projects related to border control in Lebanon

    Full text: For the last two years, Lebanese customs have been under increasing national and international pressure to tighten control and security at its borders. In this context, attention was brought to the uncontrolled movement of radioactive material across the borders. In order to address this issue, and in close coordination with the Lebanese Customs, the Project Administration Office (PAO) at the Presidency of Council of Ministers initiated an EU-funded project entitled 'Strengthening National Infrastructure related to Lebanese Trade and Border Control'. This initiative led to the establishment of several other projects in 2008 between the Lebanese government and international and foreign organizations/agencies to address the related issue of control of radioactive material movement across the borders. These are more generally described as nuclear security projects that directly beneficiate Lebanese Customs and are listed as the following: the above listed EU-funded project, the IAEA-funded project for Masnaa border, the IAEA Coordinated Research Project and the US-DOE Megaport project. They are under current implementation and come as complementary to the Northern Border Pilot Project that promotes the integrated management of Lebanon's borders, led by Germany and with contributions by the EU Commission and various countries. This paper describes the various projects involved, their programmatic plans, and the coordination needed for reaching the common objectives. (author)

  9. The Treaty of Lisbon and the European Border Control Regime

    Marianne Takle


    Full Text Available The question raised in the article is how the new provisions of the Lisbon Treaty and the Stockholm programme concerning the EU’s asylum and migration policy might consolidate existing trends within the European border control regime. The regime is defined by a combination of three features: (i a harmonisation of categories among the EU/Schengen member states, (ii a growing use of new technology in networked databases and (iii an increasing sorting of individuals based on security concerns. Although none of these features is new, the combination gives a new impetus to the European border control regime. The article concludes that the Lisbon Treaty and the Stockholm programme consolidate and strengthen existing trends. This implies that policies on border control, asylum, immigration, judicial cooperation and police cooperation are consolidated in a broader approach to border control, and that there is a strengthening of EU foreign policy within the European border control regime. The boundaries between previously dispersed policy areas are blurred. The combination of different aspects of security and various levels of authority requires coordination of policies with substantially different goals, and goes beyond mere border control.

  10. Beyond the borders of classical optical measurements

    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

  11. Inconsistency in precipitation measurements across the Alaska-Yukon border

    Scaff, L.; Yang, D.; Li, Y.; Mekis, E.


    This study quantifies the inconsistency in gauge precipitation observations across the border of Alaska and Yukon. It analyses the precipitation measurements by the national standard gauges (National Weather Service (NWS) 8 in. gauge and Nipher gauge) and the bias-corrected data to account for wind effect on the gauge catch, wetting loss and trace events. The bias corrections show a significant amount of errors in the gauge records due to the windy and cold environment in the northern areas of Alaska and Yukon. Monthly corrections increase solid precipitation by 136 % in January and 20 % for July at the Barter Island in Alaska, and about 31 % for January and 4 % for July at the Yukon stations. Regression analyses of the monthly precipitation data show a stronger correlation for the warm months (mainly rainfall) than for cold month (mainly snowfall) between the station pairs, and small changes in the precipitation relationship due to the bias corrections. Double mass curves also indicate changes in the cumulative precipitation over the study periods. This change leads to a smaller and inverted precipitation gradient across the border, representing a significant modification in the precipitation pattern over the northern region. Overall, this study discovers significant inconsistency in the precipitation measurements across the USA-Canada border. This discontinuity is greater for snowfall than for rainfall, as gauge snowfall observations have large errors in windy and cold conditions. This result will certainly impact regional, particularly cross-border, climate and hydrology investigations.

  12. Dynamic data-driven sensor network adaptation for border control

    Bein, Doina; Madan, Bharat B.; Phoha, Shashi; Rajtmajer, Sarah; Rish, Anna


    Given a specific scenario for the border control problem, we propose a dynamic data-driven adaptation of the associated sensor network via embedded software agents which make sensor network control, adaptation and collaboration decisions based on the contextual information value of competing data provided by different multi-modal sensors. We further propose the use of influence diagrams to guide data-driven decision making in selecting the appropriate action or course of actions which maximize a given utility function by designing a sensor embedded software agent that uses an influence diagram to make decisions about whether to engage or not engage higher level sensors for accurately detecting human presence in the region. The overarching goal of the sensor system is to increase the probability of target detection and classification and reduce the rate of false alarms. The proposed decision support software agent is validated experimentally on a laboratory testbed for multiple border control scenarios.

  13. Cross-Border Listings, Capital Controls, and U.S. Equity Flows to Emerging Markets

    Hali J. Edison; Francis E. Warnock


    We analyze capital flows to emerging markets in a framework that incorporates two quantitative measures of financial integration, the intensity of capital controls and the extent of cross border listings, while controlling for traditional global (push) and country specific (pull) factors. Two important results emerge. First, the cross listing of an emerging market firm on a U.S. exchange is an important but short lived capital flows event, suggesting that the cross listed stock is in effect a...

  14. Border beam against nuclear smuggling

    At present man can cross the borders with nuclear materials in a luggage without problems. A supervision system could be installed at the border as a measuring help to control the possible illicit traffic. Therefore, a pilot study was performed to compile its technical requirements and to assessing its feasibilities. The main finding was that a control system at the border is feasible. (nevyjel)

  15. Extraterritorial Border Controls and Responsibility to Protect: A View From ECRE

    Bjarte Vandvik


    Recent times have witnessed a significant decline in the number of persons seeking asylum on the territory of European Union (EU) countries. When these trends are observed in the light of Member States' continuous tightening of their border controls, it seems evident that access to the territory and to the asylum procedure is being seriously obstructed in the EU. Border management activities are no longer confined to the physical frontiers of the Member States or to the external borders of th...

  16. Measuring cross-border regional integration with composite indicators: The Oresund integration index

    Makkonen, Teemu


    Earlier quantitative studies on cross-border regional integration processes have commonly neglected science, technology and innovation (STI) indicators: even the most notable example of a composite indicator approach to measuring cross-border regional integration, i.e. the Oresund index, lacks a ...

  17. Travel and Border Health Measures to Prevent the International Spread of Ebola.

    Cohen, Nicole J; Brown, Clive M; Alvarado-Ramy, Francisco; Bair-Brake, Heather; Benenson, Gabrielle A; Chen, Tai-Ho; Demma, Andrew J; Holton, N Kelly; Kohl, Katrin S; Lee, Amanda W; McAdam, David; Pesik, Nicki; Roohi, Shahrokh; Smith, C Lee; Waterman, Stephen H; Cetron, Martin S


    During the 2014-2016 Ebola virus disease (Ebola) epidemic in West Africa, CDC implemented travel and border health measures to prevent international spread of the disease, educate and protect travelers and communities, and minimize disruption of international travel and trade. CDC staff provided in-country technical assistance for exit screening in countries in West Africa with Ebola outbreaks, implemented an enhanced entry risk assessment and management program for travelers at U.S. ports of entry, and disseminated information and guidance for specific groups of travelers and relevant organizations. New and existing partnerships were crucial to the success of this response, including partnerships with international organizations, such as the World Health Organization, the International Organization for Migration, and nongovernment organizations, as well as domestic partnerships with the U.S. Department of Homeland Security and state and local health departments. Although difficult to assess, travel and border health measures might have helped control the epidemic's spread in West Africa by deterring or preventing travel by symptomatic or exposed persons and by educating travelers about protecting themselves. Enhanced entry risk assessment at U.S. airports facilitated management of travelers after arrival, including the recommended active monitoring. These measures also reassured airlines, shipping companies, port partners, and travelers that travel was safe and might have helped maintain continued flow of passenger traffic and resources needed for the response to the affected region. Travel and border health measures implemented in the countries with Ebola outbreaks laid the foundation for future reconstruction efforts related to borders and travel, including development of regional surveillance systems, cross-border coordination, and implementation of core capacities at designated official points of entry in accordance with the International Health Regulations

  19. An Improved Objective Evaluation Measure for Border Detection in Dermoscopy Images

    Celebi, M Emre; Iyatomi, Hitoshi; Stoecker, William V; Malters, Joseph M; Grichnik, James M; 10.1111/j.1600-0846.2009.00387.x


    Background: Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, dermoscopy image analysis has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. Although numerous methods have been developed for the detection of lesion borders, very few studies were comprehensive in the evaluation of their results. Methods: In this paper, we evaluate five recent border detection methods on a set of 90 dermoscopy images using three sets of dermatologist-drawn borders as the ground-truth. In contrast to previous work, we utilize an objective measure, the Normalized Probabilistic Rand Index, which takes into account the variations in the ground-truth images. Conclusion: The results demonstrate that the differences between four of the evaluated border detection methods are in fact smaller than those predicted by ...


    Gaveika, Artūrs


    This paper reflects the problematic issues regarding the legal framework of Latvian airspace border control. Currently the legal framework in relation to airspace border control in Latvia is rather confusing and incomplete since there is no specific division between responsibilities of certain authorities and compliance to international airspace regulations as well as the competence of the NATO in the control of national airspace regime. Therefore it is essential to evaluate the functions and...

  2. Improving the measurement of cross-border securities holdings: the Treasury International Capital SLT

    Erika Brandner; Fang Cai; Ruth Judson


    In the wake of the financial crisis, growing interest in improving the measurement of cross-border securities positions and flows spurred the introduction of a new Treasury International Capital (TIC) reporting form, the TIC Security Long Term (SLT). This article reviews the existing structure of TIC cross-border position and flow data, the benefits that the new SLT can provide, and the incoming information from the first two reporting months of SLT data, September and December 2011. While so...

  3. Border Control of Nuclear and Other Radioactive Materials

    In the second half of year 2006, stationary detection systems for nuclear and other radioactive materials were installed on Border Crossing Bregana, Croatia. Yantar 2U, which is the commercial name of the system, is integrated automatic system capable of detection of nuclear and other radioactive materials prepared for fixed-site customs applications (Russian origin). Installed system contains portal monitors, camera, communication lines and communication boxes and server. Two fully functional separate systems has been installed on BC Bregana, one on truck entrance and another one on car entrance. In this article the operational experience of installed system is presented. This includes statistical analysis of recorded alarms, evaluation of procedures for operational stuff and maintenance and typical malfunction experience, as well as some of the recommendation for future use of detection systems.(author)

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

    Rebecca Miller


    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.

  5. Surveillance Unattended Foliage Penetrating Radar for Border Control and Homeland Protection

    Felicia Amato


    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.

  6. Threat of nuclear terrorism: Issues of international law, border protection, security and export control cooperation

    In 1970-1991 the IAEA dealt mainly with loyal signatories to NPT, after 1991 met challenges of non-loyal states aiming at clandestine nuclear programs (Iraq and North Korea), while after 2001 must also meet new challenge of non-loyal non-state actors aiming at obtaining nuclear materials and weapons. The task of protecting 450 tons of separated weapon grade plutonium, 1700 tons of separated HEU outside military use, as well as 2,7 tons of HEU in civilian and training reactors spread in 43 countries requires more active cooperation between the IAEA and state and inter-state structures responsible for fight against international crime, intelligence, control of borders and domestic law and order. UN SC resolutions 1269, 1368, 1373 provide some important legal basis for fight against nuclear terrorism, but special Convention on Fight Against Nuclear Terrorism need to be adopted through UN procedures. Protocol on Fight against International terrorism is required to supplement the Palermo (2000) Convention on Fight Against Transnational Organized Crime (signed as for now by 128 states). Treaty on Cooperation in Fight against Terrorism signed by the CIS states in 1999, as well as creation of the CIS Anti-Terrorist Center in 2000 could contribute to the legal means of such fight. Russia also employs Bishkek security group (within Shanghai Cooperation Organization) and 'Borjomi Four' group (security services cooperation between Russia, Armenia, Georgia, Azerbaijan) for anti-terrorist coordination. Obligations under START-1, START-II and other treaties on nuclear disarmament require from Russia to dismantle in foreseeable future about 250 nuclear reactors from submarines, about 700 SLBMs, about 150 ICBMs of SS-18 type and 400 more of other types. All that would increase stocks of fissile material beyond direct military use and would require additional protection measures. In time this task coincides for Russia with necessity to reprocess 40,000 tons of chemical weapons (task

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

    Mei-Hua Chen


    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.

  8. Some of the results of the protection measures in the field of ionizing radiation at FRY border crossings

    Full text: SUMMARY: The paper describes some of the results of the protection measures in the field of ionizing radiation at FRY border crossings where there were placed stationary monitors of gamma-radiation. The Institute of Security as licensed institution for ionizing radiation detection, designed and placed stationary devices MZ - 100 at border crossings check points named Kelebija, Horgos, Vatin, Gradina, Presevo, Djeneral Jankovic, Batrovci and the ship lock 'Djerdap-I'. CONCLUSION: Over the several years ago IAEA and its member states as well as other international organizations have become increasingly aware of the consequences which might result from illegal activities involving these materials. Therefore initiatives to strengthen physical protection regime are strongly supported and steps towards improving security of nuclear and other radioactive material have already been taken. Yugoslavia as IAEA member state wishes to contribute to the all together efforts in reducing the possibility of illegal activities such as theft, sabotage and trafficking, involving nuclear materials and other radioactive materials, and on the associated proliferation threat and radiation risks. Therefore relevant national bodies prepare project proposal titled 'PREVENTION OF ILLICIT TRAFFICKING IN NUCLEAR AND RADIOACTIVE MATERIALS IN THE FEDERAL REPUBLIC OF YUGOSLAVIA'. Significant work is ahead in this field, since harmonization of radiological control at our border crossings must be achieved. (author)

  9. Networked solutions of radiation control of state borders and urban areas

    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.

  10. Extraterritorial Border Controls and Responsibility to Protect: A View From ECRE

    Bjarte Vandvik


    Full Text Available Recent times have witnessed a significant decline in the number of persons seeking asylum on the territory of European Union (EU countries. When these trends are observed in the light of Member States' continuous tightening of their border controls, it seems evident that access to the territory and to the asylum procedure is being seriously obstructed in the EU. Border management activities are no longer confined to the physical frontiers of the Member States or to the external borders of the EU; instead, their scope has been extended well beyond these, towards the high seas and into the territory of third countries. From the European Council on Refugees and Exiles (ECRE, a pan-European network of refugee-assisting NGOs working in 30 countries, we emphasise that Member States' obligations under international and European refugee and human rights law do not stop at the physical boundaries of the EU. This includes interception operations taking place in the high seas or in the territorial waters of third countries. The EU and the Member States should recognise that the power to prevent access to the territory carries with it the responsibility to protect those in need.

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

    Maybritt Jill Alpes


    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.

    Mazurek, Tomasz; Barwiński, Marek


    1. Apart from Finnish-Russian border, Polish eastern border is one of the longest external European Union and Schengen Agreement land borders under the control of a single country. 2. For the last few years, Polish Government has significantly improved the infrastructure of Border Guard at the eastern border in order to prevent “flooding” of Europe by illegal immigrants and smuggled goods. 3. Despite this fact, Polish eastern border does not have sufficient infrastructure, especially wh...

  13. Cosmic-ray-induced ship-effect neutron measurements and implications for cargo scanning at borders

    Neutron measurements are used as part of the interdiction process for illicit nuclear materials at border crossings. Even though the natural neutron background is small, its variation can impact the sensitivity of detection systems. The natural background of neutrons that is observed in monitoring instruments arises almost entirely from cosmic-ray-induced cascades in the atmosphere and the surrounding environment. One significant source of variation in the observed neutron background is produced by the 'ship effect' in large quantities of cargo that transit past detection instruments. This paper reports on results from measurements with typical monitoring equipment of ship effect neutrons in various materials. One new result is the 'neutron shadow shielding' effect seen with some low neutron density materials

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

    Faulkner, Katelyn T; Robertson, Mark P; Rouget, Mathieu; Wilson, John R U


    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.

  15. Networked solutions of radiation control of illicit trafficking in radioactive and nuclear materials through State borders

    The radiation mobile Nuclear Protection Network system (NPNETTM) was developed. The purpose of the system is to facilitate the investigation and decision making process in the case of detection of a radiation source. NPNETTM allows on-line data exchange between a user equipped with radiation detectors, e.g. spectroscopic personal radiation detectors (SPRDs) PM1703GNB, and a remote command centre. NPNETTM is recommended for use by border guards, customs, security and emergency services. The prevention of illicit trafficking in radioactive and nuclear materials as well as the dispersion of radioactive materials in urban areas is a challenging task of national security departments in many countries. To solve this task, appropriate actions of on-site personnel equipped with radiation detectors such as fixed radiation portal monitors or mobile personal radiation detectors are required. However, users of radiation equipment such as customs, border guards and police services often perform radiation control as an additional responsibility to their main duties. Furthermore, these users do not have sufficient expertise in radiation control and need real time remote expert help to interpret readings of radiation equipment and expert support in the decision making process.

  16. Europe facing climate change - a border adjustment measure to prepare the after-Kyoto?

    Considering the different relationships between the trade framework and that of the struggle against climate change, the authors address the European Union (EU) environmental strategy within the perspective of a multilateral governance of climate changes for the after-Kyoto period. After having recalled what is at stake in a border adjustment measure and outlined the difficulties of implementation of a tax-based solution at a multilateral level, the authors present the available strategies for the EU. Then, they address the strategy based on trade liberalization as incentive to the struggle against climate changes. They discuss the derogation to standard rules and finally propose a governance system between the United Nations Framework Convention on Climate Change (UNFCCC or FCCC) and the WTO

  19. [Health control at International Borders: the role of foreign health during the containment phases of the pandemic (H1N1) 2009].

    Dávila Cornejo, Miguel; Aramburu Celigueta, Carmen; Morte Esteban, Susana; Vera Gil, Inmaculada; Iglesias García, Maria José; González Gutiérrez-Solana, Oscar


    As a public health strategy in responding to epidemics, sanitary checks at borders to delay the entry of the pandemic virus into Spain are part of the containment phases activities. Their implementation is the responsibility of the Foreign Health Department and requires a coordinated action with other agencies involved in the response. This paper describes the actions undertaken at international airports during these phases and evaluates its efficacy in the execution of their objective. We establish a hypothesis to explain how the measures undertaken by Foreign Health and the collaboration with the National Surveillance System may have contributed to delay the spread of the virus into our country. We want to emphasize the need for consolidating the border control surveillance system and improving collaboration, as well as the importance of designing a clear communication strategy for the population in these settings. Together these measures, along with others, will prevent situations of uncertainty. PMID:21203716

  20. Force-displacement measurements of earlywood bordered pits using a mesomechanical tester.

    Zelinka, Samuel L; Bourne, Keith J; Hermanson, John C; Glass, Samuel V; Costa, Adriana; Wiedenhoeft, Alex C


    The elastic properties of pit membranes are reported to have important implications in understanding air-seeding phenomena in gymnosperms, and pit aspiration plays a large role in wood technological applications such as wood drying and preservative treatment. Here we present force-displacement measurements for pit membranes of circular bordered pits, collected on a mesomechanical testing system. The system consists of a quartz microprobe attached to a microforce sensor that is positioned and advanced with a micromanipulator mounted on an inverted microscope. Membrane displacement is measured from digital image analysis. Unaspirated pits from earlywood of never-dried wood of Larix and Pinus and aspirated pits from earlywood of dried wood of Larix were tested to generate force-displacement curves up to the point of membrane failure. Two failure modes were observed: rupture or tearing of the pit membrane by the microprobe tip, and the stretching of the pit membrane until the torus was forced out of the pit chamber through the pit aperture without rupture, a condition we refer to as torus prolapse.

  4. RhoB controls endothelial barrier recovery by inhibiting Rac1 trafficking to the cell border.

    Marcos-Ramiro, Beatriz; García-Weber, Diego; Barroso, Susana; Feito, Jorge; Ortega, María C; Cernuda-Morollón, Eva; Reglero-Real, Natalia; Fernández-Martín, Laura; Durán, Maria C; Alonso, Miguel A; Correas, Isabel; Cox, Susan; Ridley, Anne J; Millán, Jaime


    Endothelial barrier dysfunction underlies chronic inflammatory diseases. In searching for new proteins essential to the human endothelial inflammatory response, we have found that the endosomal GTPase RhoB is up-regulated in response to inflammatory cytokines and expressed in the endothelium of some chronically inflamed tissues. We show that although RhoB and the related RhoA and RhoC play additive and redundant roles in various aspects of endothelial barrier function, RhoB specifically inhibits barrier restoration after acute cell contraction by preventing plasma membrane extension. During barrier restoration, RhoB trafficking is induced between vesicles containing RhoB nanoclusters and plasma membrane protrusions. The Rho GTPase Rac1 controls membrane spreading and stabilizes endothelial barriers. We show that RhoB colocalizes with Rac1 in endosomes and inhibits Rac1 activity and trafficking to the cell border during barrier recovery. Inhibition of endosomal trafficking impairs barrier reformation, whereas induction of Rac1 translocation to the plasma membrane accelerates it. Therefore, RhoB-specific regulation of Rac1 trafficking controls endothelial barrier integrity during inflammation. PMID:27138256

  5. Addressing competitiveness and leakage concerns in climate policy. An analysis of border adjustment measures in the US and the EU

    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.

  6. Solving the Border Control Problem: Evidence of Enhanced Face Matching in Individuals with Extraordinary Face Recognition Skills.

    Bobak, Anna Katarzyna; Dowsett, Andrew James; Bate, Sarah


    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. PMID:26829321

  12. Pollution Control Effort at China's River Borders: When Does Free Riding Cease?

    Kahn, Matthew E.; Pei Li; Daxuan Zhao


    At political boundaries, local leaders often have weak incentives to reduce polluting activity because the social costs are borne by downstream neighbors. This paper exploits a natural experiment set in China in which the central government changed the local political promotion criteria and hence incentivized local officials to reduce border pollution along specific criteria. Using a difference in difference approach, we document evidence of pollution progress with respect to targeted criteri...

  13. Radioactivity measurements and control solutions

    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

  15. Providing training and technical assistance to customs officers and border guards: An effective mechanism to improve export controls

    With the disintegration of the Soviet Union, an increasing international concern requiring attention is illegal trafficking in nuclear and nuclear-related dual-use commodities. For the past few years, the US government, including the Department of Energy (DOE), has assisted the former Soviet Union in establishing and enhancing national export control systems. Although US assistance has been targeted to help control approved transfers, part of the focus has shifted to prevent the illegal exit of special nuclear material, dual-use items, and other nuclear-related materials. As part of a State Department initiative, a Nonproliferation and Disarmament Fund (NDF) was established to address various nonproliferation concerns. One project, funded by NDF, US Customs Service (Customs), and the DOE, focuses on assisting transit countries to prevent illegal trafficking. DOE is providing technical expertise to seven countries in the Baltics and Central Europe to help identify materials, equipment, and technology that might transit their borders. Although there are many mechanisms to prevent illegal trafficking, this paper will discuss the importance of providing international customs officials and border guards with training and technical assistance on nuclear materials and nuclear-related dual-use items. More specifically, detail of the DOE training plan will be discussed

  16. Metrics for border management systems.

    Duggan, Ruth Ann


    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.

  17. Control of unauthorized transportation of nuclear and radioactive materials across state territories and borders - Detection, response and decision support

    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).

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

    Pia Oberoi


    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.

    textabstractInstead of abolishing internal border controls in 1992, the European Union (EU) replaced them with VAT and statistical requirements that appear to be just as onerous and costly. This paper shows that the compliance costs of the new requirements are on average 5 percent of the value of intra-EU trade of Dutch businesses. Clearly, the costs constitute a (differentiated) border tax that impedes intra-EU trade and violates the Treaty of Rome. The paper analyses the magnitude and deter...

Using a multi-dimensional measure of national cultural distance and controlling for oth...

  4. Modern technical and technological solutions of radiation control to combat illicit trafficking of nuclear and radioactive materials across borders

    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

  6. Irradiation as a Quarantine Control Measure

    One hundred and eighty-six million people passed through US borders in 1965. Of 446000 consignments inspected at US ports of entry last year, 32 000 were infested. This vast increase in international travel, exchange of goods in trade and the speed of movement from one part of the world to another, requires strict measures to prevent worldwide dissemination of ''unwanted'' insect species. Once an exotic species is established, quarantine surveys of pest abundance, distribution and jump spread, require great efforts in containment campaigns with a view to eradication. Is ''inspection'' the most economic means of combating the introduction of undesirable insect species? Is the establishment of irradiation facilities for the treatment of certain commodities, at import or export, or interstate collecting centres, a possible answer to this problem? Can irradiation of certain products replace existing techniques of fumigation? Examples are given of the possible use of irradiation to treat passengers' baggage at airports, to prevent the spread of pests of fruit crops across inter-state boundaries and for the treatment of timber at import. Sustained release of sterilized insects as a continuous control operation is considered as a possible replacement for quarantine survey and treatment of pest containment areas. (author)

  7. Identification of Novel Regulators of the JAK/STAT Signaling Pathway that Control Border Cell Migration in the Drosophila Ovary

    Saadin, Afsoon; Starz-Gaiano, Michelle


    The Janus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) signaling pathway is an essential regulator of cell migration both in mammals and fruit flies. Cell migration is required for normal embryonic development and immune response but can also lead to detrimental outcomes, such as tumor metastasis. A cluster of cells termed “border cells” in the Drosophila ovary provides an excellent example of a collective cell migration, in which two different cell types coordinate their movements. Border cells arise within the follicular epithelium and are required to invade the neighboring cells and migrate to the oocyte to contribute to a fertilizable egg. Multiple components of the STAT signaling pathway are required during border cell specification and migration; however, the functions and identities of other potential regulators of the pathway during these processes are not yet known. To find new components of the pathway that govern cell invasiveness, we knocked down 48 predicted STAT modulators using RNAi expression in follicle cells, and assayed defective cell movement. We have shown that seven of these regulators are involved in either border cell specification or migration. Examination of the epistatic relationship between candidate genes and Stat92E reveals that the products of two genes, Protein tyrosine phosphatase 61F (Ptp61F) and brahma (brm), interact with Stat92E during both border cell specification and migration.

  8. Radiation measurements and quality control

    Accurate measurements are essential to research leading to a successful radiation process and to the commissioning of the process and the facility. On the other hand, once the process is in production, the importance to quality control of measuring radiation quantities (i.e., absorbed dose, dose rate, dose distribution) rather than various other parameters of the process (i.e. conveyor speed, dwell time, radiation field characteristics, product dimensions) is not clearly established. When the safety of the product is determined by the magnitude of the administered dose, as in radiation sterilization, waste control, or food preservation, accuracy and precision of the measurement of the effective dose are vital. Since physical dose measurements are usually simpler, more reliable and reproducible than biological testing of the product, there is a trend toward using standardized dosimetry for quality control of some processes. In many industrial products, however, such as vulcanized rubber, textiles, plastics, coatings, films, wire and cable, the effective dose can be controlled satisfactorily by controlling process variables or by product testing itself. In the measurement of radiation dose profiles by dosimetry, it is necessary to have suitable dose meter calibrations, to account for sources of error and imprecision, and to use correct statistical procedures in specifying dwell times or conveyor speeds and source and product parameters to achieve minimum and maximum doses within specifications.

  9. Investigation and control of a Plasmodium falciparum malaria outbreak in Shan Special Region Ⅱ of Myanmar along the China-Myanmar Border from June to December 2014

    Hui Liu; Jian-Wei Xu; Heng-Lin Yang; Mei Li; Cheng-De Sun; Yi-Jie Yin; Zhi-Liang Zheng


    Background:From 2007 to 2013,intensive control measures reduced malaria burden by 90 % along the China-Myanmar border.However,despite these measures a P.falciparum malaria outbreak was reported in the Shan Special Region Ⅱ of Myanmar in June of 2014.Methods:Epidemiological,parasitological and entomological investigations were performed.Dihydroartemisinin piperaquine (DAPQ) was immediately administered to treat parasite positive individuals.Long lasting insecticidal nets (LLIN),indoor residual spraying ORS) with insecticides and behavior change communication (BCC) were also provided for outbreak control.An embedded efficacy study was conducted evaluating DP.Molecular genotyping via polymerase chain reaction (PCR) was performed on the Kelch gene on chromosome 13.Results:All infections were identified as Plasmodium falciparum by RDT and microscopy.Two fatalities resulted from the outbreak.The attack rate was 72.8 % (67/92) and the incidence density rate was 14.2 per 100 person-weeks.The positive rate of rapid diagnostic test (RDT) was 72.2 % (65/90) and microscopically-determine parasite rate 42.2 % (38/90).Adjusted odds ratio (OR) of multivariate logistic regression analysis for aged <15 years,15-45 years,inappropriate treatment from a private healer and lack of bed nets were 13.51 (95 % confidence interval,2.21-105.89),7.75 (1.48-44.97),3.78 (1.30-46.18) and 3.21 (1.21-15.19) respectively.In the six surrounding communities of the outbreak site,positive RDT rate was 1.2 % (4/328) and microscopically-determine parasite rate 0.6 % (2/328).Two light traps collected a total of 110 anopheline mosquitoes including local vectors,An.minimus,An.sinensis and An.maculates.After intensive control,the detection of malaria attacks,parasites and antigen were reduced to zero between July 1 and December 1,2014.The cure rate of P.falciparum patients at day 42 was 94.3 % (95 % Cl,80.8-99.3 %).The PCR did not detect K13-propeller mutations.Conclusion:Imported P

  10. Hazard control measures for lasers

    Considerable attention has been paid to the establishment of exposure limits (EL's) for laser radiation, but is has been generally not well recognized that EL's are infrequently measured in actual hazard evaluations of laser installations. Inasmuch as many laser beam irradiances are at least a thousandfold higher than applicable EL's, a very careful measurement is seldom needed. A movement of a measuring instrument a few mm from the beam axis may result in completely missing the beam. Recognition of these difficulties led to an approach in laser safety that departs from the methods followed in evaluating and controlling ionizing radiation sources

  11. Is the international border effect larger than the domestic border effect? Evidence from US trade

    Cletus C. Coughlin; Novy, Dennis


    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 U.S. states to foreign countries and combine it with trade flows between and within U.S. states. After controlling for distance and country size, we estimate that relative to state-to-state trade, crossing an ...

  13. Statistical Control of Measurement Quality

    Effective nuclear materials management, and hence design and operation of associated material control systems, depend heavily on the quality of the quantitative data on which they are based. Information concerning the reliability of the measurement methods employed is essential to both the determination of data requirements and the evaluation of results obtained. Any method of analysis should be (1) relatively free from bias and (2) reproducible, or, in more usual terminology, precise. Many statistical techniques are available to evaluate and control the reproducibility of analytical results. Economical and effective experimental designs have been developed for the segregation of different sources of measurement error. Procedures have been developed or adapted tot use in maintaining and controlling the precision of routine measurements. All of these techniques require that at least some measurements must be duplicated, but duplication of all measurements can be justified only when the detection of every gross error, or mistake, is extremely important. Three types of measurement bias can be considered: (1) bias relative to a standard, (2) bias relative to prior experience, and (3) bias relative to a group. The first refers to the degree to which the measurements obtained deviate systematically from some ''standard'' which is unbiased either (1) by definition, or (2) because all known sources of bias have been removed. The second in concerned with the presence of systematic differences over a period of time. The third type of bias concerns the relationship between different physical entities or individuals at a given time. Recent developments in statistical methodology applicable to the evaluation of all three types of bias are discussed. Examples of the use of the statistical techniques discussed on Hanford data are presented. (author)

  14. Radiation measurements and quality control

    The association between radiation measurements and quality control is established for radiation sterilization of medical products and food irradiation. Good quality control implies accurate radiation dosimetry and a discussion of the factors which can affect the accuracy of in-plant dosimetry is presented. It is argued that if systematic errors are to be avoided in in-plant dosimetry the plant operators will have to spend more time and effort in developing the skills associated with the accurate use of radiation dosemeter systems. The aims and merits of an international intercomparison programme recently set up by the IAEA are discussed. The benefits of accurate in-plant dosimetry for the operator, approving authority and purchaser are balanced against the extra dosimetric efforts required for good quality control. (author)

  15. BOOK REVIEW Quantum Measurement and Control Quantum Measurement and Control

    Kiefer, Claus


    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

  17. A model for international border management systems.

    Duggan, Ruth Ann


    To effectively manage the security or control of its borders, a country must understand its border management activities as a system. Using its systems engineering and security foundations as a Department of Energy National Security Laboratory, Sandia National Laboratories has developed such an approach to modeling and analyzing border management systems. This paper describes the basic model and its elements developed under Laboratory Directed Research and Development project 08-684.

    Panday, Arnico; Praveen, Ps; Adhikary, Bhupesh; Bhave, Prakash; Surapipith, Vanisa; Pradhan, Bidya; Karki, Anita; Ghimire, Shreta; Thapa, Alpha; Shrestha, Sujan


    The Indo-Gangetic Plains (IGP) in northern South Asia are among the most polluted and most densely populated places in the world, and they are upwind of vulnerable ecosystems in the Himalaya mountains. They are also fragmented across 5 countries between which movement of people, data, instruments and scientific understanding have been very limited. ICIMOD's Atmosphere Initiative has for the past three years been working on filling data gaps in the region, while facilitating collaborations across borders. It has established several atmospheric observatories at low and mid elevations in Bhutan and Nepal that provide new data on the inflow of pollutants from the IGP towards the mountains, as well as quantify the effects of local emissions on air quality in mountain cities. EGU will be the first international conference where these data will be presented. ICIMOD is in the process of setting up data servers through which data from the region will be shared with scientists and the general public across borders. Meanwhile, to promote cross-border collaboration among scientists in the region, while addressing an atmospheric phenomenon that affects the lives of the several hundred million people, ICIMOD' Atmosphere Initiative has been coordinating an interdisciplinary multi-year study of persistent winter fog over the Indo-Gangetic Plains, with participation by researchers from Pakistan, India, China, Nepal, Bhutan and Bangladesh. Using a combination of in-situ measurements and sample collection, remote sensing, modeling and community based research, the researchers are studying how changing moisture availability and air pollution have led to increases in fog frequency and duration, as well as the fog's impacts on local communities and energy demand that may affect air pollution emissions. Preliminary results of the Winter 2015-2016 field campaign will be shown.

  19. Surveillance and Control of Aedes albopictus in the Swiss-Italian Border Region: Differences in Egg Densities between Intervention and Non-intervention Areas.

    Tobias T Suter


    Full Text Available Aedes albopictus, the Asian tiger mosquito, originates from the tropical and subtropical regions of Southeast Asia. Over the recent decades it has been passively spread across the globe, primarily through the used tyre trade and passive transportation along major traffic routes. A. albopictus is a proven vector for many arboviruses, most notably chikungunya and dengue, with recent outbreaks also in continental Europe. In southern Switzerland, in the Canton of Ticino A. albopictus was spotted for the first time in 2003. Since then the local authorities have implemented a control programme based on larval source reduction. Despite these efforts, mosquito densities have increased over the last decade, casting doubts on the effectiveness of such larval control programmes.The Italian communities just across the Swiss-Italian border lack a control programme. This motivated us to compare the intervention and the non-intervention areas side by side in an attempt to find evidence for, or against, the effectiveness of larval A. albopictus control. Using ovitraps and a randomised sampling scheme, we examined the seasonal and spatial abundance of A. albopictus in sylvatic and urban environments across the Swiss-Italian border in 2012 and 2013. In the urban environments of the non-intervention area, egg densities were 2.26 times higher as compared to the intervention area. In the sylvatic environments, as compared to the urban environments, egg densities were 36% in the intervention area and 18% in the non-intervention area.Though alternative explanations are also valid, the results support the hypothesis that the Ticino intervention programme does have an impact. At the same time the data also suggest that current larval interventions fall short in gaining full control over the mosquito, calling for the evaluation of additional, or alternative, approaches. Ideally, these should also consider inclusion of the neighbouring Italian communities in the

  4. Enhancing knowledge and awareness of biosecurity practices for control of African swine fever among smallholder pig farmers in four districts along the Kenya-Uganda border.

    Nantima, Noelina; Davies, Jocelyn; Dione, Michel; Ocaido, Michael; Okoth, Edward; Mugisha, Anthony; Bishop, Richard


    A study was undertaken along the Kenya-Uganda border in four districts of Tororo and Busia (Uganda) and Busia and Teso (Kenya) to understand smallholder farmers' knowledge, practices and awareness of biosecurity measures. Information was collected by administering questionnaires to 645 randomly selected pig households in the study area. 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.

    In 1997, the Centers for Disease Control and Prevention, the Mexican Secretariat of Health, and border health officials began the development of the Border Infectious Disease Surveillance (BIDS) project, a surveillance system for infectious diseases along the U.S.-Mexico border. During a 3-year period, a binational team implemented an active, sentinel surveillance system for hepatitis and febrile exanthems at 13 clinical sites. The network developed surveillance protocols, trained nine surveillance coordinators, established serologic testing at four Mexican border laboratories, and created agreements for data sharing and notification of selected diseases and outbreaks. BIDS facilitated investigations of dengue fever in Texas-Tamaulipas and measles in California–Baja California. BIDS demonstrates that a binational effort with local, state, and federal participation can create a regional surveillance system that crosses an international border. Reducing administrative, infrastructure, and political barriers to cross-border public health collaboration will enhance the effectiveness of disease prevention projects such as BIDS. PMID:12533288

    The "border effect" literature finds that political borders have a very large impact on relative prices, implicitly adding several thousands of miles to trade. In this paper we show that the standard empirical specification suffers from selection bias, and propose a new methodology based on quantile regressions. Using a novel data set from Uruguay, we apply our procedure to measure the segmentation introduced by city borders. City borders should matter little for trade. We find that when the ...

  13. Probabilistic Quantum Control Via Indirect Measurement

    Mandilara, A


    The most basic scenario of quantum control involves the organized manipulation of pure dynamical states of the system by means of unitary transformations. Recently, Vilela Mendes and Mank'o have shown that the conditions for controllability on the state space become less restrictive if unitary control operations may be supplemented by projective measurement. The present work builds on this idea, introducing the additional element of indirect measurement to achieve a kind of remote control. The target system that is to be remotely controlled is first entangled with another identical system, called the control system. The control system is then subjected to unitary transformations plus projective measurement. As anticipated by Schrodinger, such control via entanglement is necessarily probabilistic in nature. On the other hand, under appropriate conditions the remote-control scenario offers the special advantages of robustness against decoherence and a greater repertoire of unitary transformations. Simulations c...

  14. Measurement and control for mechanical compressive stress

    Li, Qing; Ye, Guang; Pan, Lan; Wu, Xiushan


    At present, the indirect method is applied to measuring and controlling mechanical compressive stress, which is the measurement and control of rotating torque of screw with torque transducer during screw revolving. Because the friction coefficient between every screw-cap and washer, of screw-thread is different, the compressive stress of every screw may is different when the machinery is equipped. Therefore, the accurate measurement and control of mechanical compressive stress is realized by the direct measurement of mechanical compressive stress. The author introduces the research of contrast between compressive stress and rotating torque in the paper. The structure and work principle of a special washer type transducer is discussed emphatically. The special instrument cooperates with the washer type transducer for measuring and controlling mechanical compressive stress. The control tactics based on the rate of compressive stress is put to realize accurate control of mechanical compressive stress.

  16. Cooperative Monitoring Center Occasional Paper/8: Cooperative Border Security for Jordan: Assessment and Options

    Qojas, M.


    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.

  18. Uzbekistan: Radiation monitoring on the borders, experience and perspectives

    Full text: The measures and actions on prevention, detection and response to criminal or unauthorized acts involving radioactive materials in Uzbekistan are presented. The geographical location of Uzbekistan is convenient for illicit trafficking of nuclear and other radioactive materials. The history of technical equipping of Customs checkpoints on Uzbekistan borders with radiation detectors is presented. To solve the problem of radiation monitoring at Uzbekistan borders was possible by installing stationary radiation portal monitors (RPM) at main customs border crossings or entry points. In our case radiation portal monitors 'Yantar' produced by Russian company 'Aspect' were used. These commercial RPMs were adjusted for use in sharply continental climate of Uzbekistan by sun-protection system. Up to date in Uzbekistan 31 checkpoints were equipped with such RPMs, total amount of monitors being 200. The experience of operation of radiation monitors has shown that the majority of alarms were innocent ones caused by NORM radionuclides, mainly K-40, Th-232, U-238 in various industrial products such as building materials, ceramics, mineral fertilizers etc. Several cases of radioactivity detection in trucks, railway cars and pedestrians are analyzed. The analysis of failures occurred in RPMs and its constituents during several years of their operation is presented. The activities for further development of radiation control on the borders are presented. The experience of Uzbekistan in establishing radiation monitoring systems on its borders, their operation and technical maintenance will be useful for other countries of the region in their efforts to strengthen measures to prevent illicit trafficking of nuclear and other radioactive materials.

  19. Border control! Capillary pressure / saturation relationships in a diphasic flow in a random medium: Influence of the boundary conditions

    Fiorentino, Eve-Agnès; Toussaint, Renaud; Moura, Marcel; Jankov, Mihailo; Schäfer, Gerhard; Jørgen Måløy, Knut


    Solving problems involving biphasic flows in porous media, at a scale larger than the pore one, normally requires the use of relationships between pressure and saturation. These allow the closure of generalized Darcy flow models for two phases, commonly used in hydrology or large scale problems of diphasic flow in porous media. There are mathematical models which approximate experimental records with curve-fitting equations. The two most common models are the Brooks-Corey and van Genüchten ones, they are used to complete a system of generalized Darcy equations. The purpose of the current study is the influence of the boundary conditions on the relationship between pressure and saturation. We perform numerical simulations of drainage experiments. Water is the wetting fluid and air is the non wetting fluid. The results highlight the fact that a filter which allows only water to flow at the exit face of the system modifies both the shape of the curve and the value of the residual saturation. The pressure of the models that are commonly used does not match with the pressure of real flows since there is no filter to cross, to flow from an elementary volume to another. Experiments performed in transparent Hele-Shaw cells exhibit the same features, showing the influence of the semi permeable boundary conditions on the pressure-saturation measures obtained. This effect corresponding to the formation of localized plugging clusters at the boundaries, is obtained in slow flow conditions, and is independent of any dynamic fingering, also known to affect such relations (1,2,3). Modeling flows in open media thus would require to use the central part of the curves pressure saturation where the effect of the boundaries is the least important, or to modify properly these relationships to extract the behavior unaffected by boundaries.

  20. Border Malaria Associated with Multidrug Resistance on Thailand-Myanmar and Thailand-Cambodia Borders: Transmission Dynamic, Vulnerability, and Surveillance

    Adisak Bhumiratana


    Full Text Available This systematic review elaborates the concepts and impacts of border malaria, particularly on the emergence and spread of Plasmodium falciparum and Plasmodium vivax multidrug resistance (MDR malaria on Thailand-Myanmar and Thailand-Cambodia borders. Border malaria encompasses any complex epidemiological settings of forest-related and forest fringe-related malaria, both regularly occurring in certain transmission areas and manifesting a trend of increased incidence in transmission prone areas along these borders, as the result of interconnections of human settlements and movement activities, cross-border population migrations, ecological changes, vector population dynamics, and multidrug resistance. For regional and global perspectives, this review analyzes and synthesizes the rationales pertaining to transmission dynamics and the vulnerabilities of border malaria that constrain surveillance and control of the world’s most MDR falciparum and vivax malaria on these chaotic borders.

  13. Developments in a Cross-Border Bank Exposure "Network"

    Masazumi Hattori; Yuko Suda


    In this paper we explore the developments in the cross-border bank exposures using the BIS International Banking Statistics. To this end, we treat the web of the cross-border bank exposures as a "network" and investigate the characteristics of the network topology, and compute various statistical measures for the network topology. We find that the network of cross-border bank exposure has become more tightly connected over time. The network now has higher connectivity, a shorter average path ...

  14. Detection of radioactive materials at borders

    of Understanding (MOU) (1998) to promote co-operation at the international level in order to improve the control of radioactive materials. At the time of the drafting of this report, a similar MOU between the IAEA and the International Criminal Police Organization (INTERPOL) is pending. There are a number of measures that must be undertaken by States to combat the illicit trafficking and inadvertent movements of radioactive materials. These measures are, generally, shared between the regulatory and law enforcement agencies as part of a State's national arrangements. One of these measures id the subject of this TECDOC, namely detection of radioactive materials at borders. While effective detection involves many components of regulatory and law enforcement strategies, the major focus of this publication is on radiation detection and in particular, the instrumentation necessary for such purposes. Its intent is to assist Member State organizations in effectively detecting radioactive materials crossing their borders, whether importations, exportations, or shipments in transit. The purpose of this publication is to provide guidance for Member States for use by customs, police or other law enforcement bodies on the radiation monitoring of vehicles, people and commodities at border crossing facilities as a countermeasure to illicit trafficking and also to find inadvertent movement of radioactive materials. Such monitoring may be one component of efforts towards finding radioactive materials that have been lost from control and which may enter a Member State

    Hayakawa, Kazunobu; 早川, 和伸


    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...

  17. Real-time measurement and control at Jet. Experiment Control

    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)

    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

  3. Making transuranic assay measurements using modern controllers

    This paper describes methodology and computer-controlled instrumentation developed at the Los Alamos National Laboratory that accurately performs nondestructive assays of large containers bearing transuranic wastes and nonradioactive matrix materials. These assay systems can measure fissile isotopes with 1-mg sensitivity and spontaneous neutron-emitting isotopes at a 10-mg sensitivity. The assays are performed by neutron interrogation, detection, and counting in a custom assay chamber. An International Business Machines Personal Computer (IBM-PC) is used to control the CAMAC-based instrumentation system that acquires the assay data. 6 refs., 7 figs

    An improved beta backscatter instrument for the nondestructive measurement of the thickness of thin coatings on a substrate is described. Included therein is the utilization of a bank of memory stored data representative of isotope, substrate, coating material and thickness range characteristics in association with a control card having predetermined indicia thereon selectively representative of a particular isotope, substrate material, coating material and thickness range for conditioning electronic circuit means by memory stored data selected in accord with the predetermined indicia on a control card for converting backscattered beta particle counts into indicia of coating thickness

  5. High resolution coherent control measurements on KRb

    We present high resolution optimal control on KRb in a molecular beam. Isotopomer selective ionization is performed by closed loop experiments with a pulse shaper consisting of two liquid crystal masks with 640 pixels each. This yields a spectral resolution of 1.84 cm-1/pixel which is according to our knowledge the highest that have been used for coherent control measurements until now. The isotopomer ratio 124KRb/126KRb is optimized by pure and combined phase and amplitude modulation and the optimized pulse shapes indicate which isotopic composition of the heavier isotopomer mass 126KRb mainly contributes to our measurements. Moreover, the involved vibronic transitions are exposed in the optimized spectra

  6. BTFS: The Border Trade Facilitation System

    Phillips, L.R.


    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.

  7. Simulation of Cross-border Impacts Resulting from Classical Swine Fever Epidemics within the Netherlands and Germany.

    Hop, G E; Mourits, M C M; Oude Lansink, A G J M; Saatkamp, H W


    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

  8. Editorial: Human rights at the border

    Sverre Molland


    Full Text Available t is with great honour that I introduce the second issue of the Anti-Trafficking Review (ATR. The first issue received an overwhelming response and has placed the journal at the forefront of rigorous analysis and debate relating to human trafficking and human rights. It raised the topic of accountability in anti-trafficking. This issue hopes to further strengthen the ATR’s position as a global, reputable journal on human trafficking. Strengthening the quality of research, analysis, and reflexivity in the trafficking sector is much needed, and I echo Anne Gallagher’s observation as guest editor of the first issue that standards in anti-trafficking research tend to be less rigorous than in other fields of study. My aim as a guest editor is to contribute to addressing this shortfall by bringing together a set of diverse and insightful articles focussing on the nexus of borders and human rights. It is also my hope that this issue will work towards narrowing the divide between practitioners and academics in anti-trafficking. This is reflected in the varied range of contributors. The last few years have witnessed a significant increase in publishing relating to human trafficking worldwide. However, there is limited measured debate and appraisal of this literature within the anti-trafficking sector. For this reason we have decided to include a book review as a way of highlighting recent major publications. The question of borders, migration control, trafficking and human rights raise contested and controversial questions. The editorial team has attempted to include different perspectives, reflected in the debate section in particular. Needless to say, all papers have been subject to double blind peer review.

  10. Cardiology without borders

    Michael Wolk


    @@ Cardiovascular disease takes place in a border-free world. The challenge at the American College of Cardiology (ACC) and anywhere else in the world is to hold patient care above the artificial barriers raised by geopolitical issues. Fundamentally, the goal of ACC members or of any cardiology societies in the world is to provide excellent patient care. Cardiovascular disease is essentially the same throughout the world. Where there are minor variations among individuals, as clinicians we find priceless opportunity to learn. Expanding- rather contracting -our experience base helps us as individuals to realize our best potential as practitioners.

  11. Social and cultural influences among Mexican border entrepreneurs.

    Díaz Bretones, Francisco; Cappello, Héctor M; Garcia, Pedro A


    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. PMID:19708411

  12. Using Community Indicators to Assess Nutrition in Arizona-Mexico Border Communities

    Jacob Abarca, PharmD


    Full Text Available Introduction Community indicators are used to measure and monitor factors that affect the well-being of a community or region. Community indicators can be used to assess nutrition. Evaluating nutrition in communities along the Arizona-Mexico border is important because nutrition is related to an individual’s risk of overweight or obesity; obesity is a risk factor for developing type 2 diabetes. Methods Local grocery store purchases were selected as a community indicator for nutrition. A structured 26-question interview was developed and administered to grocery store managers in communities along the Arizona-Mexico border that were targeted by the Border Health Strategic Initiative, a program implemented by community groups and the University of Arizona. In addition, data from milk distributors serving the border communities were collected. Results Residents of these communities favor food items with a higher fat and higher caloric content. This trend held across several food categories. Major barriers to customer acceptance of healthier food items include lack of knowledge concerning healthy foods and their prices. Conclusion The demand for healthy food items is relatively low along the Arizona-Mexico border. Interventions should continue to target this population with the aim of changing dietary patterns as one method of improving the health of the community and preventing and controlling diabetes.

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

    Martha C. Hawes


    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.

  14. 碳边界调节措施对中国出口产品影响评估%The Evaluation of the Impact of Potential Border Carbon Adjustment Measures on Chinese Exports

    邱薇; 张汉林


    Copenhagen and Cacun meetings failed to reach an agreement on post-2012 global emissions reduction mechanism, however, developed economies have proposed a policy proposal on climate change and energy, including implementing unilateral trade measures. The paper evaluates how Chinese exports are vulnerable to potential border carbon adjustments based on the assessment of cost increases from the application of carbon price of $20/t CO2 equivalent or $50/t CO2 equivalent, and clearly shows that there are many uncertainties in how border carbon adjustment might be designed. The application of carbon price, the methodology of assessing the carbon content of goods, and the design detail of schemes are key factors for the vulnerability of Chinese exports to potential border carbon adjustment measures.%虽然2012年后全球温室气体减排机制尚未达成,但各国纷纷制定气候和能源法案以促进减排。为维持国内企业竞争力,防止碳泄露和能源密集型产业转移.部分国家可能会实施单边贸易措施。文章主要结合美国相关法案,作出合理政策假设,利用IPCC氧化碳排放计算方法和投入产出模型,考察潜在碳边界调节措施对中国出口影响。结果发现.中国整体出口受碳成本上升影响有限,但基本钢铁产业、化学制造产业和非矿物制造产业的出口产品受冲击较大。

  15. Quality control for overcoring stress measurement data

    The in situ state of stress is one of the key rock mechanical factors considering the safety and stability of underground excavations for civil and mining engineering purposes in greater depth, but at the same time measuring and interpretation of stress comes more difficult. Normally the in situ stress interpretation is based on final strain readings and there have not been practical and objective tools to judge transient strain behaviour during overcoring. This study was set up by nuclear waste management companies Posiva Oy (Finland) and Svensk Kaernbraenslehantering AB (Sweden) to improve the quality of interpretation of overcoring stress measurement results. The primary product of the project is quality control capability of overcoring stress measurement data. For this purpose a computer program was developed which can simulate the transient strains and stresses during the overcoring in any in situ stress and coring load conditions. The solution is based on superpositioning of elastic stresses and the basic idea can be applied also for different overcoring probes with minor modifications and recalculation of stress tensors. The measured strains can be compared to calculated ones to check if the measured transient behaviour is accordant with interpreted in situ state of stress. If not, the in situ state of stress can be calculated based any transient or final strain values. The transient stresses can be compared to strength envelope of intact rock and thereby estimate core damage potential. Technically the developed OCS-code fulfilled all the objectives and the numerical error was found to be less than 5%. The analysed case studies showed clearly the advance of having objective method study the reliability of stress measurement data. On the other hand, the interpretation of in situ state of stress from on early strains is difficult because the solution is very sensitive for measured strains and coring advance. The report also includes a comprehensive list of

  16. On the reconstruction of conductivity of bordered two-dimensional surface in R^3 from electrical currents measurements on its boundary

    Henkin, Gennadi


    An electrical potential U on bordered surface X (in Euclidien three-dimensional space) with isotropic conductivity function sigma>0 satisfies equation d(sigma d^cU)=0, where d^c is real operator associated with complex (conforme) structure on X induced by Euclidien metric of three-dimensional space. This paper gives exact reconstruction of conductivity function sigma on X from Dirichlet-to-Neumann mapping (for aforementioned conductivity equation) on the boundary of X. This paper extends to the case of the Riemann surfaces the reconstruction schemes of R.Novikov (1988) and of A.Bukhgeim (2008) given for the case of domains in two-dimensional Euclidien space. The paper extends and corrects the statements of Henkin-Michel (2008), where the inverse boundary value problem on the Riemann surfaces was firstly considered.

  17. Best available control measures for prescribed burning

    Section 190 of the Clean Air Act (CAA) as amended in 1990 requires the US Environmental Protection Agency (EPA) to issue guidance on Best Available Control Measures (BACM) of PM10 (particulate matter with a nominal aerodynamic diameter less than or equal to 10 micrometers) from urban fugitive dust, residential wood combustion, and prescribed silvicultural and agricultural burning (prescribed burning). The purpose of this guidance is to assist states (especially, but not exclusively, those with PM10 nonattainment areas which have been classified as serious) in developing a control measure for these three source categories. This guidance is to be issued no later than May 15, 1992 as required under the CAA. The guidance will be issued in the form of a policy guidance generic to all three BACM and in the form of Technical Information Documents (TIDs) for each of the three source categories. The policy guidance will provide the analytical approach for determining BACM and the TID will provide the technical information. The purpose of this paper is to present some insight from the forthcoming TID on what BACM might entail for prescribed burning in a serious PM10 nonattainment area

  18. A longitudinal analysis of cross-border ties and depression for Latino adults.

    Torres, Jacqueline M; Lee, Anne; González, Hector M; Garcia, Lorena; Haan, Mary N


    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. PMID:27239901

  19. Small islands and pandemic influenza: Potential benefits and limitations of travel volume reduction as a border control measure

    Wilson Nick


    Full Text Available Abstract Background Some island nations have explicit components of their influenza pandemic plans for providing travel warnings and restricting incoming travellers. But the potential value of such restrictions has not been quantified. Methods We developed a probabilistic model and used parameters from a published model (i.e., InfluSim and travel data from Pacific Island Countries and Territories (PICTs. Results The results indicate that of the 17 PICTs with travel data, only six would be likely to escape a major pandemic with a viral strain of relatively low contagiousness (i.e., for R0 = 1.5 even when imposing very tight travel volume reductions of 99% throughout the course of the pandemic. For a more contagious viral strain (R0 = 2.25 only five PICTs would have a probability of over 50% to escape. The total number of travellers during the pandemic must not exceed 115 (for R0 = 3.0 or 380 (for R0 = 1.5 if a PICT aims to keep the probability of pandemic arrival below 50%. Conclusion These results suggest that relatively few island nations could successfully rely on intensive travel volume restrictions alone to avoid the arrival of pandemic influenza (or subsequent waves. Therefore most island nations may need to plan for multiple additional interventions (e.g., screening and quarantine to raise the probability of remaining pandemic free or achieving substantial delay in pandemic arrival.

  20. Control measures for practices causing exposure

    Over the last 20 years, we have witnessed increasing public and government concern about the effects of technology on health and the environment in fields as varied as industry, agriculture, medicine and research. Anticipating these concerns, the International Commission for Radiological Protection (ICRP) established a system of protection applying to human activities which involve exposure from ionizing radiation emanating from an artificial or natural radiation source. This system, reflected in international regulations, enshrines the idea that, on the basis of the latest scientific knowledge, risks associated with radiation exposure can only be reduced, not entirely eliminated. The paper does not deal with the linear no threshold dose response debate. In its preamble, the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources stresses the fact that the acceptance by society of risks associated with radiation is conditional on the benefits to be gained from the use made of radiation. The search for an acceptable compromise between the risks and benefits associated with activities involving exposure to radiation constitutes the key issue as concerns the measures of control to be implemented. The strength of this system lies in its consistent application to a wide range of situations. However, over the last decade, the ICRP has developed the system by highlighting different degrees of controllability which 'influence the judgements about the reasonableness of the various control procedures'. A distinction has therefore been drawn between two types of situation: practices and interventions. The paper deals with the control measures for practices, and more specifically with the description of the categories of activities to be considered, the features of the regulatory system (scope, objective, principles) and the acceptable levels of risks. The presentation of all these topics can be found in ICRP, IAEA

  1. The Open Border

    Yago Mellado López


    Full Text Available The objective of this article is to consider the volition of boundary as an opening in otherness, establishing a dialogue with Giorgio Agamben’s work La Comunidad que viene [The community to come]. Beyond the conception of borders as demarcation, this article approaches the boundary as a construction through contact, and which produces the articulation of us/them and of the Other, and not the other way round. In this way, the volition of boundaries appears, without any desire to escape towards a common abstract space or toward an elimination of categorisation, but simply as the registering of an opening in the never-ending fabric of our identities.

  5. Border mythology: Turner and modernity

    Jorge E. Brenna B.


    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.

  6. Measurement and control of occupational noise

    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

  7. Geographical, Sociological and Metaphysical Borders

    Jacinto Choza Armenta


    Full Text Available During the different ages of history and prehistory, borders have possessed different kinds of natures. Sometimes they did not exist, at other times they have been very diffuse, while at others they have been impassable. There were no borders in the Paleolithic age, or during Greece’s Heroic Age. It was not until the creation of the city-states and the empires that borders began to be consolidated. Territorial demarcations were not very strict during the Middle Ages, either. It was in the modern age that borders acquired an impassable nature, following the birth of the modern State, and they began to weaken with the crisis of the modern State that began in the 20th century. Thus, the author claims, the construction of borders is not a fundamentally political-administrative event. Instead, it seems to be primarily a phenomenon of a cultural nature and, more specifically, of a metaphysical nature.

  8. The impact of Border policy effect on cross-border ethnic areas

    Q. L. Bie; Zhou, S. Y.; Li, C S


    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 ...


    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.

  10. SALE, Quality Control of Analytical Chemical Measurements

    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

  11. Control Measures for Human Respiratory Viral Infection.

    Bennett, Lesley; Waterer, Grant


    New viral respiratory pathogens are emerging with increasing frequency and have potentially devastating impacts on the population worldwide. Recent examples of newly emerged threats include severe acute respiratory syndrome coronavirus, the 2009 H1N1 influenza pandemic, and Middle East respiratory syndrome coronavirus. Experiences with these pathogens have shown up major deficiencies in how we deal globally with emerging pathogens and taught us salient lessons in what needs to be addressed for future pandemics. This article reviews the lessons learnt from past experience and current knowledge on the range of measures required to limit the impact of emerging respiratory infections from public health responses down to individual patient management. Key areas of interest are surveillance programs, political limitations on our ability to respond quickly enough to emerging threats, media management, public information dissemination, infection control, prophylaxis, and individual patient management. Respiratory physicians have a crucial role to play in many of these areas and need to be aware of how to respond as new viral pathogens emerge. PMID:27486741

  12. Firemen without borders


    Fire knows no borders and neither should the tools for fighting it. It was with this aim in mind that delegates from 14 different countries came to CERN at the beginning of April to take part in the twentieth of a series of twice-yearly international conferences organised by the Federation of European Union Fire Officer Associations (FEU). This latest conference allowed participants to keep abreast of new developments with a view to improving the safety techniques used in their own countries. The first in the series was held in Tampere, Finland, in 1994. The FEU network's objective is to harmonise safety policies and modernise the fire-fighting programme. In particular, it aims to develop an international system for testing hotels' fire alarm systems and to improve language learning in all countries' fire-fighting services. "We want authorities throughout Europe to be aware of the importance of a good joint fire-prevention policy in order to avoid catastrophes such as the fire that destroyed Madrid's Winds...

    THE large-scale dance drama The Border Town performed by the Hunan Provincial Troupe attracted a large audience with its natural human touch, strong local flavour and elegant literature, provoking reverie from the people. The Border Town dance drama was adapted from the novel of the same name by Shen Congwen, an influential writer on Chinese modern literature. The Border Town, written in 1934, was his masterpiece, which gives a delicate account of the young love between the orphan girl Cuicui (who was a...

  16. Border effects and border regions: Lessons from the German unification

    Nitsch, Volker


    This paper examines data on trade flows between West German Bundesländer (federal states) and East Germany to explore the effect of national borders on trade. Although the data cover only a small fraction of intra-German trade flows, I find a home bias of about factor 2.2; West German shipments to East Germany are about 120% larger than deliveries to an otherwise similar foreign country. Based on this result, possible implications for border regions are discussed

  17. Toward Definition and Measurement of Pupil Control Behaviour

  18. Measuring control structure complexity through execution sequence grammars

    MacLennan, Bruce J.


    A method for measuring the complexity of control structures is presented. It is based on the size of a grammar describing the possible execution sequences of the control structure. This method is applied to a number of control structures, including Pascal's control structures, Dijkstra's operators, and a structure recently proposed by Parnas. The verification of complexity measures is briefly discussed. (Author)

  19. Pollution of Barianwala drain and control measure

    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.

  20. The Cosmopolitanization of the EU’s Borders?

    Damian Spruce


    Full Text Available For centuries the political geography of Europe has been based around borders of its nation states. The ability of the nation state to control its territory has been essential to the practices of war and diplomacy, the legitimacy of governments, immigration policies and trade. But processes of globalization and EU integration have transformed the borders of the European nation state. While globalization theorists tend to posit an opening up of borders to global flows of capital, information and people, the changed nature of the border is itself often left unexamined and is assumed to have simply disappeared. But scholars and activists are now arguing that, rather than fading away, borders are proliferating in the globalized world and their functions spreading into many different areas of society. This article examines the transformation of the ‘classical’ border of the nation-state into its recent forms, using the work of theorists such as Balibar, Mezzadra, Rigo and Walters. It then examines how these theories have been applied in recent literature, and in particular Chris Rumford’s analysis of the European Neighbourhood policy and his argument that this represents a ‘cosmopolitanisation’ of European borders.

  3. Recent Trends in Border Economics

    Thomas M Fullerton Jr


    Greater cross-border economic integration in many regions has caused the field of border economics to expand rapidly. It has also occurred as a growing recognition of the necessity to examine economic phenomena within the unique contexts imposed by geo-political market segmentation. Some of the areas in which substantial research efforts are being directed include population, business cycle transmission, exchange rates, industrial development, labor markets, environment, and natural resources.

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

    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 60Co, even in sheet metal used for lorries or railroad cars. Such contamination can easily be caused by the routine method to control

  8. Distance and Political Boundaries. Estimating Border Effects under Inequality Constraints

    Fernando Borraz; Alberto Cavallo; Roberto Rigobon; Leandro Zipitría


    The “border effect” literature finds that political boundaries have a large impact on relative prices, implicitly adding several thousands of miles to trade. In this paper we show that the standard empirical specification suffers from selection bias, and propose a new methodology based on quantile regressions. Using a novel data set from Uruguay, we apply our procedure to measure the segmentation introduced by city borders. We find that when the standard methodology is used, two supermarkets ...

    Emmanuelle Lavallée; Vincent Vicard


    The fact that crossing a political border dramatically reduces trade flows has been widely documented in the literature. The increasing number of borders has surprisingly attracted much less attention. The number of independent countries has indeed risen from 72 in 1948 to 192 today. This paper estimates the effect of political disintegration since World War II on the measured growth in world trade. We first show that trade statistics should be considered carefully when assessing globalizatio...

  11. Borders in Education and Living- a Case of Trench Warfare.

    Hviid, Pernille


    In this paper the notion of border will be examined in a cultural life course perspective. I will investigate borders as psycho-cultural constructions created to enable and control meaning-making in the intersection between subjects engagements and concerns and collectively constructed and guiding meanings. An empirical analysis of one boy's life course in and between home, school and a Leisure Time Activity Center in the years 1st to 3rd grade demonstrates a systemic construction of borders involving him, his teachers and his parents and renders the boy to choose between becoming an engaged pupil or a dedicated son. As such, the analysis can illuminate processes of school - home interactions that work opposite of what is intended and become detrimental to children's life. In a cultural life course perspective borders show how life is maintained as meaningful and not only guide the present living but also serve as directional guides into the future. PMID:26205071

  12. Cross-Border Cholera Outbreaks in Sub-Saharan Africa, the Mystery behind the Silent Illness: What Needs to Be Done?

    Godfrey Bwire

    Full Text Available Cross-border cholera outbreaks are a major public health problem in Sub-Saharan Africa contributing to the high annual reported cholera cases and deaths. These outbreaks affect all categories of people and are challenging to prevent and control. This article describes lessons learnt during the cross-border cholera outbreak control in Eastern and Southern Africa sub-regions using the case of Uganda-DRC and Malawi-Mozambique borders and makes recommendations for future outbreak prevention and control.We reviewed weekly surveillance data, outbreak response reports and documented experiences on the management of the most recent cross-border cholera outbreaks in Eastern and Southern Africa sub-regions, namely in Uganda and Malawi respectively. Uganda-Democratic Republic of Congo and Malawi-Mozambique borders were selected because the countries sharing these borders reported high cholera disease burden to WHO.A total of 603 cross-border cholera cases with 5 deaths were recorded in Malawi and Uganda in 2015. Uganda recorded 118 cases with 2 deaths and CFR of 1.7%. The under-fives and school going children were the most affected age groups contributing 24.2% and 36.4% of all patients seen along Malawi-Mozambique and Uganda-DRC borders, respectively. These outbreaks lasted for over 3 months and spread to new areas leading to 60 cases with 3 deaths, CRF of 5%, and 102 cases 0 deaths in Malawi and Uganda, respectively. Factors contributing to these outbreaks were: poor sanitation and hygiene, use of contaminated water, floods and rampant cross-border movements. The outbreak control efforts mainly involved unilateral measures implemented by only one of the affected countries.Cross-border cholera outbreaks contribute to the high annual reported cholera burden in Sub-Saharan Africa yet they remain silent, marginalized and poorly identified by cholera actors (governments and international agencies. The under-fives and the school going children were the most

  15. Counterproliferation, Border Security and Counterterrorism Subject-Related Laws and Regulations, Including Export Control Regimes in South-Eastern European Countries

    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




    We address the question of how to identify and measure the degree of intelligence in systems. We define the presence of intelligence as equivalent to the presence of a control relation. We contrast the distinct atomic semioic definitions of models and controls, and discuss hierarchical and anticipatory control. We conclude with a suggestion about moving towards quantitative measures of the degree of such control in systems.

    P. Goldsmith


    Full Text Available The precision and programmability of robotic manipulators makes them suitable for biomechanics research, particularly when an experimental procedure must be accurately repeated multiple times. This paper describes a robotic system used to investigate biomechanical mechanisms of stroke in humans. A parallel robot manipulator is used to reproduce chiropractic manipulations on animal subjects using a 3-D vision system. An algorithm for calibrating the system is proposed and tested on the robot. An iterative learning control scheme is then introduced to improve positional accuracy. Experimental results demonstrate that the calibration procedure and learning scheme are both effective.

  18. Variation Analysis and Stability Control for Measurement Process

    ZHAO Feng-yu; MA Yi-zhong; Bo Bergman; XU Ji-chao


    Based on a two-section measuring method, a data collection sheet is formed. According to the data collected, the variation sources of a measurement process are analyzed and general guidelines for variation diagnosis are suggested. In our previous study, a method is presented to control the deviation of measurement system, but it is not sensitive to mean value variation and mean value drift. In this paper, a simplified data collection scheme via two-section measuring method is introduced to control both variation and center drift of measurement process. Based on this scheme, traditional SPC charts for variation control and EWMA chart for mean value drift are given.

    The number of possible methods of generalizing binary classification to multi-class classification increases exponentially with the number of class labels. Often, the best method of doing so will be highly problem dependent. Here we present classification software in which the partitioning of multi-class classification problems into binary classification problems is specified using a recursive control language.

  1. Technical and functional specifications for border monitoring equipment. Reference manual

    Illicit trafficking of nuclear and other radioactive material has been an issue of concern since the first seizures in the early 1990s. By the end of 2004 Member States had confirmed 540 cases, while about another 500 remain unconfirmed. Most of the confirmed cases have a criminal dimension, even if they were not for known terrorist purposes. The attacks of September 2001 in the USA dramatically emphasized the requirement for the enhanced control and security of nuclear and other radioactive material. In response to a resolution by the IAEA General Conference in September 2002 the IAEA has adopted an integrated approach to protection against nuclear terrorism. This brings together IAEA activities concerned with the physical protection of nuclear material and nuclear installations, nuclear material accountancy, detection and response to illicit nuclear trafficking, the security and safety of radioactive sources, emergency response measures - including pre-emergency measures in Member States and at the IAEA - and the promotion of State adherence to relevant international instruments. States have the responsibility for combating illicit trafficking and the inadvertent movements of radioactive material. The IAEA cooperates with Member States and other international organizations in joint efforts to prevent incidents of illicit trafficking and inadvertent movements and to harmonize policies and measures by providing relevant advice through a range of technical assistance and documents. In this context the IAEA issued a group of three technical documents, co-sponsored by the World Customs Organization, Europol and Interpol, on the inadvertent movement and illicit trafficking of radioactive material. The first is Prevention of the Inadvertent Movement and Illicit Trafficking of Radioactive Material (IAEA-TECDOC-1311), the second is called Detection of Radioactive Material at Borders (IAEA-TECDOC- 1312) and the third is Response to Events Involving the Inadvertent Movement

  2. Cross-border ties and Arab American mental health.

    Samari, Goleen


    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

  3. On Borders: From Ancient to Postmodern Times

    Bellezza, G.


    The article deals with the evolution of the concept of borders between human groups and with its slow evolution from the initial no men's land zones to the ideal single-dimension linear borders. In ancient times the first borders were natural, such as mountain ranges or large rivers until, with the development of Geodesy, astronomical borders based on meridians and parallels became a favourite natural base. Actually, Modern States adopted these to fix limits in unknown conquered territories. The postmodern thought led give more importance to cultural borders until, in the most recent times, is becoming rather impossible to fix borders in the virtual cyberspace.

  6. Radiation safety without borders initiative

    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

  7. Determinants of Cross-border Mergers and Acquisitions: A Comprehensive Review and Future Direction

    Reddy, Kotapati Srinivasa


    The purpose of this paper is to review and summarize earlier studies analyzing the determinants of cross-border mergers and acquisitions (M&As). We primarily describe the motives of cross-border acquisitions and present the market performance for corporate control transactions over the period 1994-2013. Then, we illustrate the factors affecting cross-border investments and acquisitions in various taxonomies, namely deal-specific factors, firm- and industry-specific attributes, organizational ...

    The present experiment investigated the relationship between laboratory measures of self-control and delay of gratification in children and explored several other factors that may influence self-control. In the self-control paradigm, 30 four-year-old children repeatedly chose between three reinforcers received after a delay and one reinforcer…

  9. Forecasting the electricity consumption of the Mexican border states maquiladoras

    Flores, C.E.; Phelan, P.E. [Arizona State Univ., Dept. of Mechanical and Aerospace Engineering, Tempe, AZ (United States); Mou, J.-I. [Taiwan Semiconductor Manufacturing Co., Operation Planning Div., Hsin-Chu (Taiwan); Bryan, H. [Arizona State Univ., School of Architecture, Tempe, AZ (United States)


    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%.

  10. 弱管理控制与中国企业的跨国知识转移%Low-Level Management Control and Chinese Firms' Cross-Border Knowledge Transfer

    李自杰; 李毅; 肖雯娟; 吴剑峰


    This paper employs organizational learning theory to provide an understanding of the relationship be-tween management control policy of acquired firm and Chinese firm's knowledge-transfer. Through multiple-case study of three Chinese firms, this paper examines the mechanism under which low-level control of acquired firm facilitates Chinese firm's knowledge-transfer. Based on organizational learning theory and results of case study, this paper comes up with the theoretical model of management control and cross-border knowledge transfer, which indi-cates that cooperation willingness of acquired firm's employees and culture barrier influenced by management con-trol policy will have an impact on effective knowledge transfer.%  基于组织学习理论探讨跨国并购中的管理控制策略与中国企业知识转移之间的关系。通过对三家中国企业的案例比较研究发现,对目标公司的弱控制会促进中国企业知识转移的进程,提出了管理控制与跨国知识转移的理论模型,并认为管理控制策略主要是通过作用于员工的合作意愿和文化差异对知识转移的有效性产生影响的。

  11. Analytical chemistry measurements quality control program using computer applications

    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

  12. Control Rights, Pyramids, and the Measurement of Ownership Concentration

    Edwards, Jeremy S.S.; Alfons J. Weichenrieder


    Abstract The recent corporate governance literature has emphasised the distinction between control and cash-flow rights but has disregarded measurement issues. Control rights may be measured by immediate shareholder votes, the voting rights as traced through ownership chains, or voting power indices that may or may not trace ownership through chains. We compare the ability of various measures to identify the effects of ownership concentration on share valuation using a German panel...

  17. Impact of European Food Safety Border Inspections on Agri-Food Exports: Evidence from Chinese Firms

    Beestermöller, Matthias; Disdier, Anne-Célia; Fontagné, Lionel Gérard


    The cost of complying with a sanitary standard is certain. However, such regulatory measure is a source of uncertainty for exporting firms in relation to border rejections. Shipments may fail to pass inspections and may be refused entry into the importing country. We examine how the risk of rejection at European borders is affecting Chinese agri-food exporters. We combine information on rejections with Chinese firm-level export data. Border rejections amplify the turnover among firms at the e...

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

    Saskia Sassen


    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.

  3. Cross-border merger and domestic welfare

    Arijit Mukherjee


    We consider the welfare effect of cross-border merger in presence of international R&D competition. Cross-border merger increases domestic welfare if the bargaining power of the foreign firm and the slope of the marginal cost of R&D are sufficiently low. Otherwise, domestic welfare is lower under cross-border merger.

  4. The impact of Border policy effect on cross-border ethnic areas

    Bie, Q. L.; Zhou, S. Y.; Li, C. S.


    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.

    Full Text Available The present study is focused on one of the main economic problems of our time, the study of regional economic convergence and economic growth with consideration to institutions. The study conducts a literature review on the theoretical and empirical works of economic growth, with emphasis in regional economic convergence and institutions. The empirical and theoretical analysis is centered on the regional convergence of the Mexican states taking into consideration institutional and border state factors. The empirical analysis estimates an annual rate of convergence that varies from -0.018% to 4.1% for the period between 1970 and 2001, when controlling for human capital, institutional and border effects.

  19. Root Border Cells and Their Role in Plant Defense.

    Hawes, Martha; Allen, Caitilyn; Turgeon, B Gillian; Curlango-Rivera, Gilberto; Minh Tran, Tuan; Huskey, David A; Xiong, Zhongguo


    Root border cells separate from plant root tips and disperse into the soil environment. In most species, each root tip can produce thousands of metabolically active cells daily, with specialized patterns of gene expression. Their function has been an enduring mystery. Recent studies suggest that border cells operate in a manner similar to mammalian neutrophils: Both cell types export a complex of extracellular DNA (exDNA) and antimicrobial proteins that neutralize threats by trapping pathogens and thereby preventing invasion of host tissues. Extracellular DNases (exDNases) of pathogens promote virulence and systemic spread of the microbes. In plants, adding DNase I to root tips eliminates border cell extracellular traps and abolishes root tip resistance to infection. Mutation of genes encoding exDNase activity in plant-pathogenic bacteria (Ralstonia solanacearum) and fungi (Cochliobolus heterostrophus) results in reduced virulence. The study of exDNase activities in plant pathogens may yield new targets for disease control. PMID:27215971

  8. Computerized interactive measurement control system at the Rocky Flats Plant

    Traditionally, measurement control for the Rocky Flats Plant Analytical Laboratories has been administered by the Chemistry Standards Laboratory (CSL); both groups are under the jurisdiction of the Quality Engineering and Control Department. In the past, control samples were prepared by CSL, submitted to an Anlaytical Laboratory, and results were compiled by hand and submitted to the plant's central computing center which then generated a statistical report. The old paper-driven system has been replaced by the IMECS, an acronym for ''Interactive Measurement Evaluation and Control System.'' The IMECS is a computerized, interactive measurement control system developed in-house with the cooperation of computer programmers, statisticians, analytical chemists, and standards engineers. The software is structured in three parts: (1) a data base section; (2) a statistical analysis section; and (3) supporting routines used for file maintenance, updating, scheduling, and control. This paper describes how the system was conceived and designed. The paper also details the implementation of the system (scheduled for January 1985), and how it compares to the previous measurement control system

  9. Web interface for control of spent fuel measurements at FCF

    The material control and accountancy system for the Fuel Conditioning Facility (FCF) initially uses calculated values for the mass flows of irradiated EBR-11 driver fuel to be processed in the electrorefiner. These calculated values are continually verified by measurements performed by the Analytical Laboratory (AL) on samples from the fuel element chopper retained for each chopper batch. Measured values include U and Pu masses, U and Pu isotopic fractions, and burnup (via La and Tc). When the measured data become available, it is necessary to determine if the measured and calculated data are consistent. This verification involves accessing two databases and performing standard statistical analyses to produce control charts for these measurements. These procedures can now be invoked via a Web interface providing: a timely and efficient control of these measurements, a user-friendly interface, off-site remote access to the data, and a convenient means of studying correlations among the data. This paper will present the architecture of the interface and a description of the control procedures, as well as examples of the control charts and correlations

  10. Measurements of Control Rod Worths in Critical and Exponential Assemblies

    Control rods of cadmium, stainless steel and a Cd -In -A g alloy have been investigated by means of three different methods: (a) Measurements of buckling differences and migration areas in a zero-power reactor (R0); (b ) Pulsed subcritical measurements in RO with a compact neutron pulse generator; and (c ) Buckling measurements in an exponential assembly (ZEBRA). The measurements were made in different lattices of natural uranium metal rods and heavy water. Radial and axial statistical weights for one and two control rods were measured by means of method (a) with an accuracy in ΔB2 of 0.005 m-2. The upper limit in the value of ΔB2 is about -1.5 m-2, equivalent to -4% of reactivity. The accuracy in the pulsed measurements is of the order of 5%, but in this case it is possible to measure very large negative reactivities. In the exponential assembly we have tried to separate the thermal and epithermal absorption effects by measuring the control-rod worths with only moderator in the tank as well as in different reactor lattices. The accuracy was of the same order as in the critical measurements. (author)

  11. Capacitary measures for completely monotone kernels via singular control

    Alfonsi, Aurélien


    We give a singular control approach to the problem of minimizing an energy functional for measures with given total mass on a compact real interval, when energy is defined in terms of a completely monotone kernel. This problem occurs both in potential theory and when looking for optimal financial order execution strategies under transient price impact. In our setup, measures or order execution strategies are interpreted as singular controls, and the capacitary measure is the unique optimal control. The minimal energy, or equivalently the capacity of the underlying interval, is characterized by means of a nonstandard infinite-dimensional Riccati differential equation, which is analyzed in some detail. We then show that the capacitary measure has two Dirac components at the endpoints of the interval and a continuous Lebesgue density in between. This density can be obtained as the solution of a certain Volterra integral equation of the second kind.

  12. An alternative approach to control measurements of crane rails.

    Marjetič, Aleš; Kregar, Klemen; Ambrožič, Tomaž; Kogoj, Dušan


    Horizontal and vertical positions of points for the control assessment of crane rails are classically determined separately. The procedure is time consuming and causes non-homogenous accuracy of the horizontal and vertical position of control points. The proposed alternative approach is based on polar measurements using a high accuracy total station instrument and a special platform with two precise surveying prisms fixed on it. Measurements are carried out from a single station thus ensuring a common coordinate system and homogenous accuracy. The position of the characteristic point of a rail is derived from the measured positions of both prisms with known geometry of the platform. The influence of platform non-horizontality is defined, along with its elimination procedure. Accuracy assessment is ensured with redundant measurements. Result of the proposed procedure is a numerical and graphical presentation of characteristic points. The control parameters required in international Eurocode standards are easily determined from them. PMID:22778621

  13. State borders in ETRS89 coordinates – reality or fiction ?

    Jiří Poláček


    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.

  14. Tracing of border trap behavior by noise analysis in microelectronics

    The present state of art of this work is to study the electrical defects of the silicon- silicon dioxide interface created by gamma rays (Co60) in submicron MOS devices used in telecommunication systems. We focus our investigation on a particular class of trapped charge located near the interface characterized as the border traps. The expected physical location and chemical structure of the traps were discussed. The low frequency 1/f noise measurement is used in the estimation of border trap densities before and after irradiation; the results are reported for n-MOS transistor exposed to doses (0.3, 0.5, 1 and 10 Mrad). The border trap population in the irradiated samples increased from 7.6*1010 up to 1.03*1011 eV-1 Cm-2

  15. Alignment control network scheme design and measurement of HLS upgrade

    Background: In order to open up the application field and improve the source, the Hefei Light Source (HLS) is taken a major upgrade. Purpose: The paper mainly introduces the way of building and measuring of alignment control network during the HLS upgrade. Methods: The global horizontal control network points' data are measured by total station. All control network points' 3D-measurement data are obtained by laser tracker and elevation data are got by N3 Level. The function of Unified Spatial Metrology Network (USMN) of SA software is used to make a three dimensional adjustment combining data from different devices. The concept of measurement uncertainty is used to describe the measurement quality of network points. In order to check the correctness of the adjustment result, the software of MAA was employed to make three-dimensional adjustment as well as plane adjustment done by SURVEY adding elevation adjustment by NASEW2003. Results: Through the actual measurement and data processing, the accuracy of actual measurement is 0.09 mm, better than the designed accuracy of 0.15 mm. Compared with the results adjustment by different software, the result of SA is demonstrated to be reliable. Conclusion: The result demonstrates that the designed scheme of alignment control network of HLS upgrade is reasonable and feasible. (authors)

  16. 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.

    Unilateral or sub-global policies to combat climate change are potentially sensitive to free-riding and carbon leakage.

  19. Volume-controlled hydrologic property measurements in triaxial systems

    Olsen, Harold W.; Willden, Arthur T.; Kiusalaas, Nicholas J.; Nelson, Karl R.; Poeter, Eileen P.


    New capabilities for hydrologic property measurements in triaxial systems include: (1) volume-controlled and simultaneous measurements of hydraulic conductivity and one-dimensional consolidation (or specific storage) of a saturated test specimen; and (2) volume-controlled measurements of hydraulic conductivity, matric potential, and the variation of these properties with the moisture content of an unsaturated test specimen. Data on saturated kaolinite demonstrate simultaneous hydraulic-conductivity and one-dimensional consolidation tests with continuous monitoring of both vertical and horizontal effective stresses. Data on well-graded silty sand demonstrate the feasibility of concurrent constant-flow hydraulic conductivity and mattic potential measurements, and the variation of these properties with moisture content, for undisturbed and unsaturated specimens mounted in triaxial cells. Refinements needed to realize the full potential of these capabilities include a more rigid triaxial cell to minimize compliance, and an improved technique for measuring hydraulic-head differences within an unsaturated test specimen.

  20. Labour-market in a border-area; searching for jobs and the influence of borders

    B. Martin R. van der Velde


    At the moment borders, border-related problems, and the process of tearing down borders are very much in the centre of interest. Especially in Europe a lot of scientific work is done with regard to borders of countries, to determine their role in the ongoing integration process. In this respect border-regions are considered to be able to play a catalytic role. The borderland economies on both sides of a national border in this view have to be changed into one transborder economy. Initiatives ...



    A new concept called intelligent virtual control (IVC), which can be driven by measuring functions, is put forward. This small "intelligent measurement instrument unit (IMIU)", carrying with functions of instrument, consists of different types of intelligent virtual instrument (IVI) through individual components together as building blocks and can be displayed directly on the computer screen. This is a new concept of measuring instrument, and also an important breakthrough after virtual instrument (VI). Virtual control makes instrument resources obtain further exploitation. It brings about a fundamental change to the design and manufacturing mode. The instrument therefore, can not only be produced directly inside a PC, but the product is involved in the "green product" system. So far, all the present digital instruments will grow to be replaced by intelligent control with green characteristics.

  2. Delayless acceleration measurement method for motion control applications

    Vaeliviita, S.; Ovaska, S.J. [Helsinki University of Technology, Otaniemi (Finland). Institute of Intelligent Power Electronics


    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.

  3. Global Observer-based Attitude Controller Using Direct Inertial Measurements

    Saâdi Bouhired


    Full Text Available In this work, we address the problem of global attitude control using direct inertial measurements. When using direct inertial measurement to observe the rigid body attitude, it is shown that due to a geometrical obstruction, it is impossible to achieve global asymptotic stability. In fact, for a particular initial condition the tracking error quaternion converges to a pure imaginary quaternion formed by an eigenvector of a characteristic matrix related to the inertial constant and known vectors. Our proposition consists of adding a dynamic signal to force the rigid body to escape from such a situation. The proposed observer-based controller is synthesized based on a single Lyapunov function and a stability analysis shows that the controller stabilizes globally and asymptotically the rigid body attitude at the desired one. The effectiveness of the proposed observer-based controller is confirmed by simulation results.

  5. Buddhism on the Border: Shan Buddhism and Transborder Migration in Northern Thailand

    Tadayoshi Murakami


    Full Text Available This paper examines the transformation of Shan Buddhism in the border area of Northern Thailand. Shan and other ethnic groups have a long history of migration between Northern Thailand and the Shan State of Myanmar; the migration continued even after the border was demarcated at the end of the nineteenth century. Recently, the migration has become unidirectional—from Myanmar to Thailand— and the number of migrants is growing steadily. An anomalous situation exists in this area: a fluid border crossing of people, goods, and information in spite of rigid border control by the Thai government. In the religious sphere, the Thai government has been institutionalizing and standardizing “Thai Buddhism” since the early twentieth century. The government’s efforts seem to have succeeded, resulting in the unified organization of “State Sangha” and a systematized curriculum for monastic education. In the process, local Sanghas (Buddhist monastic communities in the kingdom have been integrated into the State Sangha of Thailand. However, Shan Buddhism in the border area has not been totally assimilated into Thai Buddhism and maintains its unique seasonal festivals, religious rites of passage, practices using Shan manuscripts, and temple architecture. By focusing on the movement of people in the border area, where strong state control and a porous border coexist, this paper analyzes the important role of border migration in the continuation and development of Shan Buddhist practices in Northern Thailand.

  6. Individual pitch control of wind turbines using local inflow measurements

    Thomsen, Sven Creutz; Niemann, Hans Henrik; Poulsen, Niels Kjølstad


    This paper describes a model based control approach for individually adjusting the pitch of wind turbine blades and thereby attenuating the effect of asymmetric wind loads. It is assumed that measurements of local inflow along each blade are available. This effectively provides an estimate of the...... load distribution along the blades. The load estimates are used in a predictive setup where inflow measured by one blade is used as basis for calculating future loads for the other blades. Simulations with a full stochastic wind field illustrate the effectiveness of the individual pitch controller as...

    Federica Cerina; Alessandro Chessa; Fabio Pammolli; Massimo Riccaboni


    We investigate the impact of borders on the topology of spatially embedded networks. Indeed territorial subdivisions and geographical borders significantly hamper the geographical span of networks thus playing a key role in the formation of network communities. This is especially important in scientific and technological policy-making, highlighting the interplay between pressure for the internationalization to lead towards a global innovation system and the administrative borders imposed by t...
