    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

    International Nuclear Information System (INIS)

    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

    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

    2012-01-01

    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

    International Nuclear Information System (INIS)

    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

    CERN Multimedia

    2015-01-01

    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

    Science.gov (United States)

    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

    International Nuclear Information System (INIS)

    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

    Directory of Open Access Journals (Sweden)

    2012-08-01

    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

    International Nuclear Information System (INIS)

    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

    2015-12-01

    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

    2013-06-01

    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.

    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

    2010-01-01

    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 ...

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?

    Directory of Open Access Journals (Sweden)

    Rebecca Miller

    2013-09-01

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

    Directory of Open Access Journals (Sweden)

    Felicia Amato

    2013-06-01

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

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

    International Nuclear Information System (INIS)

    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

    Directory of Open Access Journals (Sweden)

    Mei-Hua Chen

    2015-06-01

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

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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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.

    2008-09-01

    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

    Directory of Open Access Journals (Sweden)

    Maybritt Jill Alpes

    2015-09-01

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

    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

    International Nuclear Information System (INIS)

    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

    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

    International Nuclear Information System (INIS)

    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?

    International Nuclear Information System (INIS)

    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

    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

    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.

    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

    International Nuclear Information System (INIS)

    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.

    2016-01-01

    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

    2011-08-01

    Full Text Available The main security problem that any state faces today is protecting itscitizens in countering organised crime and terrorism. Wars between states are lessfrequent than in previous eras. Border defence and border security are distinctmissions requiring different forces with different training and different equipment.Border defence is predominately against the armed forces of other states requiringtanks, aircraft and ships. Traditionally, border security includes the mission roles ofimmigration, crime, agriculture, finance, disease control and terrorism. Intelligencegathering and analysis using three methodologies - trends and patterns, frequency,and probability – provides a solution to the large and expensive armed forces forterritorial border defence and defines the ability to succeed in border security.

  13. Radioactivity measurements and control solutions

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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.

    Energy Technology Data Exchange (ETDEWEB)

    Duggan, Ruth Ann

    2009-07-01

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

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

    International Nuclear Information System (INIS)

    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

    Directory of Open Access Journals (Sweden)

    Pia Oberoi

    2013-07-01

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

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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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)

    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

    International Nuclear Information System (INIS)

    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.

    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

    International Nuclear Information System (INIS)

    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

    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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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)

    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

    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.

    Directory of Open Access Journals (Sweden)

    Tobias T Suter

    2016-01-01

    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

    2016-04-01

    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

  13. Probabilistic Quantum Control Via Indirect Measurement

    CERN Document Server

    Mandilara, A

    2004-01-01

    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...

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

    2001-12-01

    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.

    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.

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

    International Nuclear Information System (INIS)

    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.

    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.

    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.

    The objective of this paper is to show how a formal approach to networks can make a significant contribution to the study of cross-border trade in West Africa. Building on the formal tools and theories developed by Social Network Analysis, we examine the network organization of 136 large traders in...... and cooperation shared among local traders, and on the distant ties developed with foreign partners from a different origin, religion or culture. Studying the spatial structure of trade networks, we find that in those markets where trade is recent and where most of the traders are not native of the...... region, national borders are likely to exert a greater influence than in those regions where trade has pre-colonial roots. Combining formal network analysis and ethnographic studies, we argue, can make a significant contribution to the current revival of interest in cross-border trade in the policy field....

  14. Detection of radioactive materials at borders

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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)

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 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

    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.

    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.

    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.

    Jacob Abarca, PharmD

    2005-01-01

    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

    Directory of Open Access Journals (Sweden)

    Martha C. Hawes

    2016-01-01

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

    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

    International Nuclear Information System (INIS)

    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.

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

    2010-01-01

    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

    International Nuclear Information System (INIS)

    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

    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

    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

    International Nuclear Information System (INIS)

    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

    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

    2011-07-01

    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

    International Nuclear Information System (INIS)

    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

    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.

  9. GEOCHEMICAL CONTROLS ON NUCLEAR MAGNETIC RESONANCE MEASUREMENTS

    International Nuclear Information System (INIS)

    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.

    International Nuclear Information System (INIS)

    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

    2016-08-01

    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

    International Nuclear Information System (INIS)

    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?

    Directory of Open Access Journals (Sweden)

    Damian Spruce

    2007-08-01

    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.

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

    International Nuclear Information System (INIS)

    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

    Abstract: This paper investigates household purchasing behavior in response to differing alcohol and tobacco taxes near an international border. Our study suggests that large tax differentials near borders induce economically important tax avoidance behavior that may limit a government’s ability to raise revenue and potentially undermine the pursuit of important health and social policy goals. We match novel supermarket scanner and consumer expenditure data to measure the size and scope of...

    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.

    2016-03-01

    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?

    Directory of Open Access Journals (Sweden)

    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

    International Nuclear Information System (INIS)

    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.

    2006-01-01

    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.

    2002-01-01

    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.

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

    International Nuclear Information System (INIS)

    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.

    Science.gov (United States)

    Samari, Goleen

    2016-04-01

    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.

    2013-11-01

    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

    International Nuclear Information System (INIS)

    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

    2004-07-01

    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%.

    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。

    International Nuclear Information System (INIS)

    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

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

    Directory of Open Access Journals (Sweden)

    Saskia Sassen

    2015-12-01

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

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

    2013-11-01

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

    This paper investigates the geographical and organizational patterns of scientific collaboration, in terms of co-authored scientific articles, in the Danish-German border region of Southern Jutland-Schleswig. The motivation behind the approach lies in the fact that scientific collaboration in...... border regions, in general, and the studied region, in particular, has rarely been discussed in the academic literature. The integration model of cross-border regional innovation systems provides the conceptual framework for the task. The paper, thus, gives methodological insights for the measurement of...... cross-border integration of knowledge infrastructures. The analysis reveals that collaborating with partners close but on the opposite side of the border is rare. Instead, cross-border collaboration takes place with partners from more faraway international research organizations. The reasons behind this...

    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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    CERN Document Server

    Alfonsi, Aurélien

    2012-01-01

    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.

    2012-01-01

    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 ?

    2015-12-01

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

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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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.

    1994-01-01

    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.

    2002-01-01

    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.

    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

    Directory of Open Access Journals (Sweden)

    Saâdi Bouhired

    2014-04-01

    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

    Directory of Open Access Journals (Sweden)

    Tadayoshi Murakami

    2012-08-01

    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.

    2001-02-01

    Full Text Available A two-dimensional sagittally symmetric human-body model was established to simulate an optimal trajectory for manual material handling tasks. Nonlinear control techniques and genetic algorithms were utilized in the optimizations to explore optimal lifting patterns. The simulation results were then compared with the experimental data. Since the kinetic measures such as joint reactions and moments are vital parameters in injury determination, the importance of comparing kinetic measures rather than kinematical ones was emphasized.

    International Nuclear Information System (INIS)

    For the calibration of noise standards the output signal of a standard measuring system has to be recorded and averaged over large time intervals. The output signal is a low-frequency noise signal, which is recorded with a fast data acquisition system, using a Siemens on-line computer. This system is also used for data processing and for the evaluation of parameters to control the standard measuring system. (orig./RW)

  13. Measures for product control during the treatment of radioactive waste

    International Nuclear Information System (INIS)

    Process control during conditioning of the wastes can be used as a very appropriate measure to perform the task of quality assurance. This contribution aims to outline what such a process control would look like in practice. A number of examples is examined dealing with wastes typically arising during the operation of nuclear power plants and during MOX fuel fabrication. The examples also cover treatment by the waste generator or a hired service company, with stationary or mobile facilities. It is found that the system of process control as introduced by the paper could be adopted for all examples. (orig./PW)

  14. Obtaining the borders of urban areas

    CERN Document Server

    Comin, Cesar Henrique; Costa, Luciano da Fontoura

    2015-01-01

    The access to an ever increasing amount of information in the modern world gave rise to the development of many quantitative indicators about urban regions in the globe. Therefore, there is a growing need for a precise definition of how to delimit urban regions, so as to allow proper respective characterization and modeling. Here we present a straightforward methodology to automatically detect urban region borders. The method is based on the density of street crossings around a single seed point associated to the urban area of interest. We exemplify the potential of the methodology by characterizing the geometry and topology of 21 urban regions obtained from 8 distinct countries. The geometry is studied by employing the lacunarity measurement, which is associated to the regularity of holes contained in a pattern. The topology is analyzed by associating the betweenness centrality of the streets with their respective class, such as motorway or residential, obtained from a database.

    The paper constitutes the slightly revised version of a legal opinion given to those local authorities in Germany which are affected by the construction of the Cattenom powerplant centre in France near to her borders with Germany and Luxembourg. In this opinion, especially claims were examined which might be raised by local authorities according to public and private law, or by the inhabitants of frontier areas, constituting, among other things, claims to the information required, to necessary measures to be taken for the safety of the population and for environmental protection, and ways and means of enforcing them. In addition, the power plant owner's civil liability for the damaging effects of power plant operation are examined as well as the international liability of the state which builds power plants.

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

    Directory of Open Access Journals (Sweden)

    P. Hristov

    2015-08-01

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

  5. Power-over-ethernet for remote measurement and control

    International Nuclear Information System (INIS)

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

  12. Measurement and Control of Emission in Two Wheelers

    Directory of Open Access Journals (Sweden)

    Sarin K Kumar

    2014-05-01

    Full Text Available Vehicle emissions are a significant contributor to ambient pollution, especially in urban areas. In general, developing countries experience higher levels of traffic-related pollution compared to developed countries due to the lack of pollution control measures. Since numerous studies document adverse health effects from vehicle emission exposure, there is a need of developing some measures for the control of exhaust and non –exhaust emissions produced by the two wheelers. In four wheeler vehicles many measures are taken to reduce the exhaust and non –exhaust emission. In my thesis work I worked to understand those steps which can be implemented with the two wheelers for to reduce the formation of emission like CO, HC, NOX, and CO2.

    2014-01-01

    Purpose: The purpose of this paper is to describe the food landscape of Texas using the CDC’s Modified Retail Food Environment (mRFEI) and to make comparisons by border/non-border. Methods: The Modified Retail Food Environment index (mRFEI (2008)) is an index developed by the CDC that measures what percent of the total food vendors in a census track sell healthy food. The range of values is 0 (unhealthy areas with limited access to fruits and vegetables) to (100—Healthy). These data were linked to 2010 US Census socioeconomic and ethnic concentration data. Spatial analysis and GIS techniques were applied to assess the differences between border and non-border regions. Variables of interest were mRFEI score, median income, total population, percent total population less than five years, median age, % receiving food stamps, % Hispanic, and % with a bachelor degree. Results: Findings from this study reveal that food environment in Texas tends to be characteristic of a “food desert”. Analysis also demonstrates differences by border/non-border location and percent of the population that is foreign born and by percent of families who receive food stamps. Conclusions: Identifying the relationship between socioeconomic disparity, ethnic concentration and mRFEI score could be a fundamental step in improving health in disadvantage communities, particularly those on the Texas-Mexico border.

  3. Novel Cross-Border Approaches to Optimise Identification of Asymptomatic and Artemisinin-Resistant Plasmodium Infection in Mobile Populations Crossing Cambodian Borders.

    Directory of Open Access Journals (Sweden)

    Hannah M Edwards

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

    International Nuclear Information System (INIS)

    Projects are constructed with huge investments in money, time and effort and therefore it is essential that they perform well during the intended life period. The reliability so expected can only be ensured by achieving the desired quality in construction. Quality mainly depends upon the effective controlling of materials used in construction, work procedures adopted, personnel performing the important functions and work environment and also ensuring proper documentation. The above fact has been well recognized during construction of the Project at Kalpakkam under Dept. of Atomic Energy. The control measures which have been designed and successfully implemented for achieving the quality are presented. (author)

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

    Directory of Open Access Journals (Sweden)

    Aija Lulle

    2016-04-01

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

Three microscopes were employed to check the parallelism and can therefore guarantee a delicate measurement of the distance between the target and the stopper. This new plunger made a successful performance in the test experiment and the measured lifetime of the 2+→0+ transition in 78Kr is in agreement with the previous value. (authors)

    Full Text Available To cooperate means to work and act together for a common advantage or purpose. The cooperation across borders, between different countries and regions sharing the same border, to reach common goals, is aimed to increase the overall competitiveness of the regional economy and to improve the quality of living standards for the these areas. European Union’s programmes are good accelerators for cross-border cooperation. The paper is focused on cross-border cooperation programmes at the external border of the EU and the expected impact of the allocated funds. The cross-border cooperation programmes are creating the conditions to exist the relationships between different social and economic stakeholders in order to contribute to economic and social development by supporting SME development, innovation, human resources development, civil society and local communities, increasing educational, social, cultural and sporting exchanges, improving local governance in different cross-border areas.

  12. Halon inerting as a hydrogen control measure for Sequoyah

    International Nuclear Information System (INIS)

    Halon inerting after accident initiation has been proposed as a hydrogen control measure for the Sequoyah nuclear plant containment building. A literature search was carried out and simple analyses were performed in order to assess the pros and cons of using Halon and to develop a design concept for an inerting system. The most significant problem associated with Halon use in a nuclear plant appears to be decomposition of the Halon into corrosive gases and liquids

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

    2013-09-01

    Full Text Available Trends in telecommunications show that customers require still more and more bandwidth. If the telecommunication operators want to be successful, they must invest a lot of money to their infrastructure and they must ensure required quality of service. The telecommunication operators would devote to development in this area. The article deals with quality of service in IP networks. Problems of quality of service can be solved through admission control methods based on measurements. These admission control methods take care of control of incoming traffic load. New flow can be accepted only if needed quality of service is ensured for it and without quality of service breach causing of already accepted flows. In the article were made description of simulations and results of simulations for Voice over IP, constant bit rate and video sources. Simulations were realized in Network simulator 2 environment. These simulations were evaluated on the base of some parameters such as: estimated bandwidth, utilization and loss rate.

    We tested refugee camp residents on the Thailand-Myanmar border for Taenia solium infection. Taeniasis prevalence was consistent with that for other disease-endemic regions, but seropositivity indicating T. solium taeniasis was rare. Seropositivity indicating cysticercosis was 5.5% in humans, and 3.2% in pigs. Corralling pigs and providing latrines may control transmission of these tapeworms within this camp. PMID:26401787

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

    International Nuclear Information System (INIS)

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

    1999-08-01

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

    Science.gov (United States)

    Silva-Filho, Waldomiro J; Dazzani, Maria Virgínia

    2016-03-01

    In this article, we explore a fundamental issue of Cultural Psychology, that is our "capacity to make meaning", by investigating a thesis from contemporary philosophical semantics, namely, that there is a decisive relationship between language and rationality. Many philosophers think that for a person to be described as a rational agent he must understand the semantic content and meaning of the words he uses to express his intentional mental states, e.g., his beliefs and thoughts. Our argument seeks to investigate the thesis developed by Tyler Burge, according to which our mastery or understanding of the semantic content of the terms which form our beliefs and thoughts is an "incomplete understanding". To do this, we discuss, on the one hand, the general lines of anti-individualism or semantic externalism and, on the other, criticisms of the Burgean notion of incomplete understanding - one radical and the other moderate. We defend our understanding that the content of our beliefs must be described in the light of the limits and natural contingencies of our cognitive capacities and the normative nature of our rationality. At heart, anti-individualism leads us to think about the fact that we are social creatures, living in contingent situations, with important, but limited, cognitive capacities, and that we receive the main, and most important, portion of our knowledge simply from what others tell us. Finally, we conclude that this discussion may contribute to the current debate about the notion of borders. PMID:26111737

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

    2007-01-01

    Full Text Available We analyze Test Driven Development (TDD from cognitive and social perspectives. Based on our analysis, we suggest a technique for controlling and monitoring the TDD process by examining measures that relate to the size and complexity of both code and tests. We call this approach Measured TDD. The motivation for TDD arose from practitioners' tendency to rush into code production, skipping the required testing needed to manufacture quality products. The motivation for Measured TDD is based on difficulties encountered by practitioners in applying TDD. Specifically, with the need to frequently refactor the unit, after every few test and code steps have been performed. We found that the suggested technique enables developers to gain better control over the development process.

    Khelif, D.; Bluth, R. T.; Jonsson, H.; Barge, J.

    2014-12-01

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

  6. Control Rod Worth Measurement in Monju Restart Core

    International Nuclear Information System (INIS)

    The Japanese prototype fast breeder reactor (FBR) Monju resumed the system startup test (SST) in May 2010 after fourteen year and five month suspension since the sodium leakage of the secondary heat transport system in December 1995. Core confirmation test (CCT) is the first step of SST which consists of three steps, and finished in July 2010. Valuable basic data for FBR development was obtained in CCT, such as reactor physics data of the core which contained 1.5wt%/HM in average of Am-241 accumulated due to the Pu-241 decay during the long-term suspension. Control rod reactivity worth measurement was carried out to calibrate the reactivity worth of control rods and to confirm the core characteristics such as excess reactivity and reactivity shutdown margin to be satisfied with safety criteria. The high prediction accuracy of the core management code system was demonstrated based on the measured data. Furthermore, the examination was conducted to shorten the measurement period. (author)

  7. Measurements and simulation of controlled beamfront motion in the Laser Controlled Collective Accelerator

    Yao, R.L.; Destler, W.W.; Striffler, C.D.; Rodgers, J.; Scgalov, Z.

    1989-01-01

    In the Laser Controlled Collective Accelerator, an intense electron beam is injected at a current above the vacuum space charge limit into an initially evacuated drift tube. A plasma channel, produced by time-sequenced, multiple laser beam ionization of a solid target on the drift tube wall, provides the necessary neutralization to allow for effective beam propagation. By controlling the rate of production of the plasma channel as a function of time down the drift tube, control of the electron beamfront can be achieved. Recent experimental measurements of controlled beamfront motion in this configuration are presented, along with results of ion acceleration experiments conducted using two different accelerating gradients. These results are compared with numerical simulations of the system in which both controlled beamfront motion and ion acceleration is observed consistent with both design expectations and experimental results. 5 refs., 6 figs.

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

  9. Environmental exposure of road borders to zinc

    International Nuclear Information System (INIS)

    The emissions of zinc along roads originating from tyre wear, corrosion of safety fence and other traffic-related sources have been quantified and validated by measured long-term loads in road run-off and airborne solids (drift) for 29 published case studies. The distribution pattern over the road border at various distances from the edge of the paved surface is assessed on the basis of 38 published case studies with measured concentrations in soil. For the impact assessment, the road border is differentiated into a zone that is part of the 'technosphere' and the 'target zone' beyond that technosphere that can be considered as part of the receiving environment. The 'technosphere' of the road includes the central reservation, the hard and the soft shoulder or, if one or both shoulders are not present, the so-called obstacle 'free zone' that is defined by road engineers. Pollution within the technosphere may require appropriate management of solid disposal and isolation from groundwater to prevent further distribution of pollutants to the environment. In the target zone along regional roads, the zinc load is about 4 mg/m2 year and this is of the same order of magnitude as that of atmospheric deposition in areas beyond the influence of roads (background). In the target zone along highways, the zinc load is increased in comparison to the background deposition. The average load of about 38 mg/m2 year is similar to that in fertilised agricultural land. Because most of the emitted zinc stays in the technosphere, the total amount entering this target zone along highways is limited. From the 140 tons of zinc per year that is released from tyre wear in The Netherlands, 64 tons is emitted in the urban area, 6.5 tons reaches to the target zones of all roads and only 1.1 tons of zinc will enter the target zone along highways. This amount will be further decreased by the application of porous asphalt in the near future. The emission from safety fence corrosion does not enter the

    Full Text Available Lymphatic filariasis caused by Wuchereria bancrofti and Brugia malayi is an important public health problem in India. Both parasites produce essentially similar clinical presentations in man, related mainly to the pathology of the lymphatic system. Filariasis is endemic in 17 States and six Union Territories, with about 553 million people at risk of infection. The Government of India has accorded a high priority for elimination of this infection through mass chemotherapy programme (annual, single dose of Diethylcarbamazine citrate, i.e. DEC - 6 mg/kg of bodyweight, plus Albendazole repeated four to six times. This campaign has become a part of the National Vector-Borne Disease Control Programme in 2003 under the National Health Policy 2002 and aims to eliminate filariasis by 2015. We discuss here the epidemiology and current control strategy for filariasis; highlighting key issues, challenges and options in the implementation of the programme, and suggesting measures for mid-course corrections in the elimination strategy.

    2016-01-01

    Visceral leishmaniasis is a deadly parasitic disease that is transmitted via the bite of a female sand fly, Phlebotomus argentipes. The highest burden of this disease is in northern India. In 2005, India embarked on an initiative with Nepal, Bangladesh, and the World Health Organization to eliminate visceral leishmaniasis by 2015. With the goal of 1 case in 10,000 people still unmet, it is prudent to evaluate the tools that have been used thus far to reduce vector numbers and cases of the disease. Herein, we present a review of studies conducted on vector-control strategies in India to combat visceral leishmaniasis including indoor residual spraying, insecticide-treated bed nets, environmental modification, and feed-through insecticides. This review suggests that the quality of indoor residual spraying may enhance control measures while a combination of spraying, nets, and feed-through insecticides would best confront the diverse habitats of P. argentipes.

  12. Development of an integrated control and measurement system

    International Nuclear Information System (INIS)

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

This technique is based on the observation of the rotational Brownian motion of gold nanocrescent particles, which possess a strong anisotropic light interaction due to their plasmonic properties. Rotational scattering correlation spectroscopy performed on a single nanoparticle is able to determine the local temperature with high accuracy. These nano-thermometers can simultaneously play the role of nano-heaters when absorbing the light of a focused laser beam. (paper)

    Full Text Available The purpose of this paper is to emphasize the linkage between establishing crossborder relations and tourism development by focusing on ten tourism projects implemented under Hungary-Romania Cross-Border Co-operation Programme (2007-2013. The study area comprises the two neighbouring counties of Satu Mare and Szabolcs-Szatmár-Bereg, the border connecting two areas characterised by social and economic similarities. Building on a solid foundation, as the first Hungarian-Romanian cross-border initiatives were launched nearly two decades ago, the two counties work together towards the shared aim of developing business infrastructure, cross-border trade, culture and tourism. The present study examines the relevance of cross-border projects viewed from the perspective of sustainable tourism development in two peripheral counties featuring similar resources. Moreover, the investigation is based on consultation of project documents, reports and promotional materials, against the theoretical framework of cross-border cooperation and regional development.

    Official crime data is generally limited by restrictions of quality and access. Rio de Janeiro in Brazil provides an example of the problems involved in measuring the homicide rate in a developing country, including the lack of proper crime reporting and the use of separate categories to reduce the number of homicides in official crime reports. Using longitudinal data, we can explain differences between the official homicide rate and alternative calculations that consider otherwise neglected categories. The interests of politicians, police, business, and citizens contribute to the difficulties in measuring and controlling homicides in the city.

    International Nuclear Information System (INIS)

    This paper reports on EPA Compliance which is a large factor in the cost of producing steam. Much of this cost stems from maintenance of optical and/or extractive SO2 Monitors. Downstream from a wet scrubber, the optical or extractive monitor usually does not work. A newly developed in situ SO2 Probe that uses the solid electrolyte technique of measurement, provides an accurate, continuous, on line measurement of SO2 for Certification to EPA Performance Specifications and control of the SO2 removal system. Moreover, the system is justifiable on the basis of cost savings in operation and maintenance. The virtually maintenance free in situ SO2 Analyzer is similar to and used with the field proven in situ zirconium oxide SO2 Analyzer. The SO2 Probe uses a potassium sulfate electrochemical cell for the determination of stack gas SO2 levels

    2013-01-01

    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 and highlights the interplay of the internationalization pressure toward a global innovation system against the administrative borders imposed by the national and continental institutions. In this study we introduce an outreach index to quantify the impact of borders on the community structure and apply it to the case of the European and US patent co-inventors networks. We find that (a) the US connectivity decays as a power of distance, whereas we observe a faster exponential decay for Europe; (b) European network communities essentially correspond to nations and contiguous regions while US communities span multiple states across the whole country without any characteristic geog...

  2. The role of transportation control measures in California's air pollution control strategy

    International Nuclear Information System (INIS)

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

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

  4. HB-Line Material Control and Accountability Measurements at SRS

    International Nuclear Information System (INIS)

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

    REX Control System is a professional advanced tool for design and implementation of complex control systems that belongs to softPLC category. It covers the entire process starting from simulation of functionality of the application before deployment, through implementation on real-time target, towards analysis, diagnostics and visualization. Basically it consists of two parts: the development tools and the runtime system. It is also compatible with Simulink environment, and the way of implementation of control algorithm is very similar. The control scheme is finally compiled (using RexDraw utility) and uploaded into a chosen real-time target (using RexView utility). There is a wide variety of hardware platforms and real-time operating systems supported by REX Control System such as for example Windows Embedded, Linux, Linux/Xenomai deployed on SBC, IPC, PAC, Raspberry Pi and others with many I/O interfaces. It is modern system designed both for measurement and control applications, offering a lot of additional functions concerning data archiving, visualization based on HTML5, and communication standards. The paper will sum up possibilities of its use in educational process, focused on control of case studies of physical models with classical and advanced control algorithms.

    Like many other countries in the world, China and Vietnam are now faced with criminals who abduct and sell women and children, which is the ugliest form of human behavior. The purpose for this crime is a common concern and different social situations and changes will generate different purposes, which can be roughly divided into categories such as sex exploitation, labor exploitation, marriage of the poor, reproduction of the male offspring and old age care. Besides, the purposes of cross-border crime might be different because of their different nationalities. The Chinese government spares no effort to crack down such crimes, no matter whether they are committed inside or outside its territory. However, to eradicate the crimes needs the uprooting of their bases and the full cooperation in the international community.

  10. Some lessons learned from developing, testing and using border monitoring equipment for the last decade

    International Nuclear Information System (INIS)

    An experience gained by several countries in creating systems of border (customs) radiation control for the last decade since the beginning of the well-known ITRAP program provides a possibility to learn definite lessons and to assess the promising progress of international efforts aimed to combat illicit trafficking in nuclear and other radioactive materials across the state borders and territories. The main result and lessons learned are that the specialized equipment is required to solve tasks of border (customs) radiation control; at the same time, developers and manufacturers of equipment, on one hand, and developers of standards and recommendations, on the other hand, are much concerned with the only technical part of radiation control; the main efforts are made to search new technical solutions, detectors, electronics, etc.; new and very expensive equipment has appeared (spectroscopic portal monitors, radiation scanners, etc). However recent research indicated that the effectiveness of using such equipment significantly depends on the operation procedures, e.g. according to developed concept of 'two-tier approach' the plastic based portal monitors are used for the primary control in the 'pass-through' mode at the first tier, and the spectroscopic portal monitor is used at the second tier in the 'stand-in' mode. The recent tests of this approach showed promising results. Previous research made by the authors for gamma-neutron personal radiation detectors and backpacks also showed that, without properly elaborated operation procedures, the use of these instruments in the real field conditions is very questionable and, sometimes, even not possible. Operation procedures means here: (i) definition of scenarios of radiation control; (ii) analysis of possible places of installation or application of equipment; (iii) definition of the maximum distance between a detector and the probable worst case of appearance of a radioactive source; (iv) definition of the minimum

  11. Radiation monitoring at the borders - Important part of nuclear security

    International Nuclear Information System (INIS)

    Full text: Three factors place Central Asia and Uzbekistan as its part in a key global non-proliferation position: the proximity of nuclear neighbours, the proximity of states and other groups seeking nuclear/radioactive material and know-how, and indigenous sources of nuclear/radioactive material. The nuclear threat is of special concern because of the proximity of major nuclear states such as Russia and China, states with nuclear ambitions such as Iran, and non-state actors potentially seeking nuclear and/or radioactive materials. In addition, Central Asia possesses currently functioning nuclear facilities widely using powerful radioactive sources from Soviet times and active uranium mines. The geographical location of Uzbekistan is convenient for illicit trafficking of nuclear materials. In conditions of increasing threat of nuclear terrorism, when extremist organizations arc threatening to mankind with terrorist attacks including the use of nuclear devices or radiological dispersal and exposure devices ('dirty' bomb), the problem to stop illicit trafficking of nuclear and radioactive materials is becoming the world one. In the frame of the Second Line of Defence (SLD) Core Program which is part of the Office of the Second Line of Defence, in the Office of International Material Protection and Cooperation of the US Department of Energy's National Nuclear Security Administration Uzbekistan borders were equipped with radiation control devices. The mission of the Core Program is to rapidly reduce the risk of nuclear proliferation and illicit trafficking of special nuclear and other radiological materials by cooperating with host countries to improve their detection and interdiction capabilities at strategic international border crossings, mid-sized seaports, and airports. To solve the problem of radiation monitoring in Uzbekistan was possible by installing stationary portal radiation monitors at main customs border crossings or entry points. Their high sensitivity

    We have developed a surgical robotic system for femoral fracture reduction employing indirect traction. Indirect traction in fracture reduction is a generally used surgical method for preventing complications such as bone splits caused by high stress on bones. For traction, a patient's foot is gripped by a jig and pulled to the distal side. Indirect traction has the advantage of distributing bone stress by utilizing a strong traction force; however, this procedure does not accurately control the proper positioning of fractured fragments when a surgical robot is used. The human leg has knee and an ankle joints, and thus robotic motion presents problems in not being able to directly propagate reduction motion to a fractured femoral fragment, rendering control of bone position difficult. We propose a control method for fracture reduction robots using external force/torque measurements of the human leg to achieve precise fracture reduction. Results showed that the proposed method reduced repositioning error from 6.8 mm and 15.9 degrees to 0.7 mm and 5.3 degrees, respectively. PMID:19163404

    The acceleration of investigations in Speech Recognition allows to augur, in the next future, a wide establishment of Vocal Control Systems in the production units. The communication between a human and a machine necessitates technical devices that emit, or are submitted to important noise perturbations. The vocal interface introduces a new control problem of a deterministic automaton using uncertain information. The purpose is to place exactly the automaton in a final state, ordered by voice, from an unknown initial state. The whole Speech Processing procedure, presented in this paper, has for input the temporal speech signal of a word and for output a recognised word labelled with an intelligibility index given by the recognition quality. In the first part, we present the essential psychoacoustic concepts for the automatic calculation of the loudness of a speech signal. The architecture of a Time Delay Neural Network is presented in second part where we also give the results of the recognition. The theory of the fuzzy subset, in third part, allows to extract at the same time a recognised word and its intelligibility index. In the fourth part, an Anticipatory System models the control of a Sequential Machine. A prediction phase and an updating one appear which involve data coming from the information system. A Bayesian decision strategy is used and the criterion is a weighted sum of criteria defined from information, minimum path functions and speech intelligibility measure.

    Coal-fired electric power generation accounts for 65% of U.S. emissions of sulfur dioxide (SO2), 22% of nitrogen oxides (NOx), and 37% of mercury (Hg). The proposed Clear Air Interstate Rule (CAIR) and Clean Air Mercury Rule (CAMR) will attempt to regulate these emissions using a cap-and-trade program to replace a number of existing regulatory requirements that will impact this industry over the next decade. Mercury emissions remain the largest source that has not yet been efficiently controlled, in part because this is one of the most expensive to control. Mercury is a toxic, persistent pollutant that accumulates in the food chain. During the coal combustion process, when both sampling and accurate measurements are challenging, we know that mercury is present in three species: elemental, oxidized and particulate. There are three basic types of mercury measurement methods: Ontario Hydro Method, mercury continuous emission monitoring systems (CEMS) and sorbent-based monitoring. Particulate mercury is best captured by electrostatic precipitators (ESP). Oxidized mercury is best captured in wet scrubbers. Elemental mercury is the most difficult to capture, but selective catalytic reduction units (SCRs) are able to convert elemental mercury to oxidized mercury allowing it to be captured by wet flue gas desulfurization (FGD). This works well for eastern coals with high chlorine contents, but this does not work well on the Wyoming Powder River Basin (PRB) coals. However, no good explanation for its mechanism, correlations of chlorine content in coal with SCR performance, and impacts of higher chlorine content in coal on FGD re-emission are available. The combination of SCR and FGD affords more than an 80% reduction in mercury emissions in the case of high chlorine content coals. The mercury emission results from different coal ranks, boilers, and the air pollution control device (APCD) in power plant will be discussed. Based on this UAEPA new regulation, most power plants

    Modeling traffic flow is stochastic in nature due to randomness in variables such as vehicle arrivals and speeds. Due to this and due to complex vehicular interactions and their manoeuvres, it is extremely difficult to model the traffic flow through analytical methods. To study this type of complex traffic system and vehicle interactions, simulation is considered as an effective tool. Application of homogeneous traffic models to heterogeneous traffic may not be able to capture the complex manoeuvres and interactions in such flows. Hence, a microscopic simulation model for heterogeneous traffic is developed using object oriented concepts. This simulation model acts as a tool for evaluating various control measures at signalized intersections. The present study focuses on the evaluation of Right Turn Lane (RTL) and Channelised Left Turn Lane (CLTL). A sensitivity analysis was performed to evaluate RTL and CLTL by varying the approach volumes, turn proportions and turn lane lengths. RTL is found to be advantageous only up to certain approach volumes and right-turn proportions, beyond which it is counter-productive. CLTL is found to be advantageous for lower approach volumes for all turn proportions, signifying the benefits of CLTL. It is counter-productive for higher approach volume and lower turn proportions. This study pinpoints the break-even points for various scenarios. The developed simulation model can be used as an appropriate intersection lane control tool for enhancing the efficiency of flow at intersections. This model can also be employed for scenario analysis and can be valuable to field traffic engineers in implementing vehicle-type based and lane-based traffic control measures.

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

  20. Measurement and timing-control techniques of femtosecond electron pulse

    International Nuclear Information System (INIS)

    Updated techniques and results on the measurement and timing-control of femtosecond electron pulses are presented. Radiation emitted by an electron pulse was measured by a femtosecond streak camera, a Michelson interferometer, a 10-channel polychromator and a fluctuation method in order to estimate a longitudinal pulse shape of the electron pulse. Measurements by the streak camera, the interferometer and the polychromator agree with one another within the error of 20%, while that by the fluctuation method was different. The numerical simulation explained the reason for it that the transverse emittance of the electron pulse affects the fluctuation of incoherent Cherenkov radiation. The synchronization of the electron pulse with the femtosecond laser pulse was also carried out. The timing jitter was 330 fs in rms and the hours-long drift was more than 1 ps. The suppression of the drift is under way by introducing a stable water cooler (within 0.01 deg. C) for the accelerator tubes and RF gun, and an air-conditioner (within 2 deg. C)

    2008-01-01

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

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

    This article aims to analyze the malaria surveillance situation on the triple border between Brazil, Colombia, and Peru. This was a qualitative study using questionnaires in the border towns in 2011. The results were analyzed with the SWOT matrix methodology, pointing to significant differences between the malaria surveillance systems along the border. Weaknesses included lack of linkage between actors, lack of trained personnel, high turnover in teams, and lack of malaria specialists in the local hospitals. The study also showed lack of knowledge on malaria and its prevention in the local population. The strengths are the inclusion of new institutional actors, improvement of professional training, distribution of insecticide-treated bed nets, and possibilities for complementary action between surveillance systems through cooperation between health teams on the border. Malaria control can only be successful if the region is dealt with as a whole. PMID:24356695

    International Nuclear Information System (INIS)

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

    The feasibility of developing a new online monitoring technique based on the characteristic acoustic response of gas bubbles in a liquid has been investigated. The method is intended to monitor the chemistry of the liquid through its relation to the bubble sound frequency. A low-temperature model consisting of water and alcohol mixtures was established, and the frequency of bubbles rising under varying concentrations of methanol was measured. It was shown that the frequency of the sound created by bubble pulsation varies with the percentage of alcohol in water. The frequency drops sharply with the increase in methanol content up to 20 wt pct, after which the decreases is gradual. Surface tension seems to be a critical liquid property affecting the sound frequency through its two-fold effects on the bubble size and the pulsation domain. The dependence between the frequency and the liquid composition suggests the feasibility of developing an acoustic-based technique for process control purposes.

  8. Control of authenticity of Tyrolean milk by stable isotope measurements

    International Nuclear Information System (INIS)

    Full text: Consumers are willing to pay elevated prices for specific product qualities, e.g. for food from a certain region, therefore the declaration of origin of these products needs to be controlled. Conventionally this is done by estimating the flow of goods and by controlling the documentation accompanying the products. However, this means are often not sufficient to detect intentional deception. The measurement of the stable isotope composition of products offers the possibility to investigate the product itself. The stable isotope ratios of the elements H, C, N, O and S are varying geographically due to diverse environmental conditions (e.g.: climate, geology, soil, altitude, geography) thus creating individual patterns for each region. These patterns are transferred in different ways into plants and animals originating from a certain region. Therefore analysis of the stable isotope pattern is a potent tool for geographic differentiation. Tyrolean milk is regarded as a high quality good produced under strict regulations in a special (alpine) environment. To protect Tyrolean milk from incorrectly declared milk originating from other regions/countries, stable isotope investigations have been carried out over a period of one year on samples from all regions of Tyrol. Samples have been measured for isotopic composition of H, C, N and O. The observed variation in the isotopic pattern of the Tyrolean milk within the year can be explained by different feeding regimes during summer and winter. Comparison of the isotopic pattern of the Tyrolean milk and milk samples of the same age from other regions gives evidence for significant differences in the isotope ratios. As the investigated 'non-Tyrolean' samples have been produced in neighbouring regions that should have similar isotopic signals due to comparable environmental conditions, presumably it should be even easier to distinguish between milk from farther regions and milk from Tyrol.

    Full Text Available One of the objectives of the European Union enshrined in 67 alin.(1 (ex-art. 61 TCE and ex-art. 29 TUE of the consolidated version of the Treaty on European Union is to create a common European space of security and justice without internal frontiers, in which to ensure the free movement of people, corralated with appropriate measures on external border controls , asylum , immigration, and crime prevention and combating. This is a long term goal that requires active cooperation of Member States and multiple efforts by EU institutions. The institutional functioning practice has shown that the clasic forms of judicial cooperation do not have the ability to complete this objective and that is necessary to create specialized structures. In this context the First European institutional structure was established in 2002, a specialized agency of the European Union, named Eurojust, with the main objective to promote and improve coordination and cooperation between the judicial authorities of the Member States in the fight against serious cross-border crime affecting the European Union. Tasks of Eurojust and relations with other European bodies, particularly the Council and Commission are established by Decision 2002/187 / JHA amended by Decision 2009/426 / JHA Council of 16 December 2008 It is exercised by College Eurojust or through its national members.

    Full Text Available Abstract Background The systolic dyssynchrony index (SDI has been introduced as a measure of mechanical dyssynchrony using three-dimensional echocardiography to select patients who may benefit from cardiac resynchronization therapy (CRT. However, three-dimensional echocardiography may be inadequate in a number of patients with suboptimal acoustic window and no single echocardiographic measure of dyssynchrony has proven to be of value in selecting patients for CRT. Thus, the aim of this study was to determine the value of cardiovascular magnetic resonance (CMR for the assessment of the SDI in patients with reduced LV function as well as in healthy controls using semi-automatic border tracking. Methods We investigated a total of 45 patients including 35 patients (65 ± 8 years with reduced LV function (EF 30 ± 11% and a wide QRS complex as well as 10 control subjects (42 ± 21 years, EF 70 ± 11%. For cine imaging a standard SSFP imaging sequence was used with a temporal resolution of 40 frames per RR-interval. Quantitative analysis was performed off-line using a software prototype for semi-automatic border detection. Global volumes, ejection fraction and the SDI were calculated in each subject. SDI was compared with standard echocardiographic parameters of dyssynchrony. Results The mean SDI differed significantly between patients (14 ± 5% and controls (5 ± 2%, p Conclusion The results of this preliminary study suggest that CMR with semi-automatic border detection may be useful for the assessment of mechanical dyssynchrony in patients with reduced LV function. No trial registration due to recruitment period between October 2004 and November 2006

  12. A modified GHG intensity indicator: Toward a sustainable global economy based on a carbon border tax and emissions trading

    International Nuclear Information System (INIS)

    It will be difficult to gain the agreement of all the actors on any proposal for climate change management, if universality and fairness are not considered. In this work, a universal measure of emissions to be applied at the international level is proposed, based on a modification of the Greenhouse Gas Intensity (GHG-INT) measure. It is hoped that the generality and low administrative cost of this measure, which we call the Modified Greenhouse Gas Intensity measure (MGHG-INT), will eliminate any need to classify nations. The core of the MGHG-INT is what we call the IHDI-adjusted Gross Domestic Product (IDHIGDP), based on the Inequality-adjusted Human Development Index (IHDI). The IDHIGDP makes it possible to propose universal measures, such as MGHG-INT. We also propose a carbon border tax applicable at national borders, based on MGHG-INT and IDHIGDP. This carbon tax is supported by a proposed global Emissions Trading System (ETS). The proposed carbon tax is analyzed in a short-term scenario, where it is shown that it can result in a significant reduction in global emissions while keeping the economy growing at a positive rate. In addition to annual GHG emissions, cumulative GHG emissions over two decades are considered with almost the same results. - Highlights: ► An IHDI-adjusted GDP (IHDIGDP) is introduced to universally account the activities of nations. ► A modified GHG emission intensity (MGHG-INT) is introduced based on the IHDIGDP. ► Based on green and red scenarios, admissible emissions and RED percentage are introduced. ► The RED percentage is used to define a border carbon tax (BCT) and emission trading system. ► The MGHG-INT can provide a universal control on emissions while allowing high economical growth

    Territorial subdivisions and geographic borders are essential for understanding phenomena in sociology, political science, history, and economics. They influence the interregional flow of information and cross-border trade and affect the diffusion of innovation and technology. However, most existing administrative borders were determined by a variety of historic and political circumstances along with some degree of arbitrariness. Societies have changed drastically, and it is doubtful that currently existing borders reflect the most logical divisions. Fortunately, at this point in history we are in a position to actually measure some aspects of the geographic structure of society through human mobility. Large-scale transportation systems such as trains and airlines provide data about the number of people traveling between geographic locations, and many promising human mobility proxies are being discovered, such as cell phones, bank notes, and various online social networks. In this chapter we apply two optimiz...

    Laser beam propagation underwater is becoming an important research topic because of high demand for its potential applications. Namely, ability to image underwater at long distances is highly desired for scientific and military purposes, including submarine awareness, diver visibility, and mine detection. Optical communication in the ocean can provide covert data transmission with much higher rates than that available with acoustic techniques, and it is now desired for certain military and scientific applications that involve sending large quantities of data. Unfortunately underwater environment presents serious challenges for propagation of laser beams. Even in clean ocean water, the extinction due to absorption and scattering theoretically limit the useful range to few attenuation lengths. However, extending the laser light propagation range to the theoretical limit leads to significant beam distortions due to optical underwater turbulence. Experiments show that the magnitude of the distortions that are caused by water temperature and salinity fluctuations can significantly exceed the magnitude of the beam distortions due to atmospheric turbulence even for relatively short propagation distances. We are presenting direct measurements of optical underwater turbulence in controlled conditions of laboratory water tank using two separate techniques involving wavefront sensor and LED array. These independent approaches will enable development of underwater turbulence power spectrum model based directly on the spatial domain measurements and will lead to accurate predictions of underwater beam propagation.

  15. Measurement approaches to support future warhead arms control transparency

    International Nuclear Information System (INIS)

    Transparency on warhead stockpiles, warhead dismantlement, and fissile material stockpiles in nuclear weapons states will become increasingly important in the move beyond START II toward lower quantities of warheads. Congressional support for further warhead reductions will likely depend on the degree of irreversibility, or in other words, the rapidity with which warhead inventories could be reconstituted. Whether irreversibility considerations can be satisfied will depend on monitoring dismantlement as well as constraining the available stockpile of fissile materials for possible refabrication into warheads. Measurement techniques designed to address the above problems will need to consider NPT Article 1 obligations as well as Russian and US classification regulations, which prohibit or restrict the transfer of nuclear warhead design information to other states. Classification considerations currently limit the potential completeness of future inspections of weapons materials. Many conventional international safeguards approaches are not currently viable for arms control applications because they would reveal weapons design information. The authors discuss a variety of technical measures that may help to improve transparence of warhead and fissile material stockpiles and may enable limited warhead dismantlement transparency

  16. Physical measurements for quality control in industrial radiation sterilization

    International Nuclear Information System (INIS)

    The use of ionizing radiation has brought about a growing industry for the sterilization of disposable surgical equipment, medical supplies, and containers for biological specimens. For many products, irradiation has become an alternative to autoclaving or gas treatment by ethylene oxide. Over fifteen years of experience with industrial sterilization by cobalt-60 gamma radiation have shown that radiation methods provide a clear advantage over gas sterilization, in that sterilization can be performed on non-permeable sealed packages. Moreover, regulatory agencies, such as the Food and Drug Administration in the U.S.A., are reappraising the requirements for sterility assurance. For products released to the public, consideration is now being given to the use of physical dosimetry, i.e., the measurement of radiation dose by physical methods. This is based on a knowledge of the microbial burden of the product before sterilization and on the probability of killing microorganisms by a given radiation dose. Because physical dosimetry is easier to control and less complicated than biological tests, it may be considered in the future the basis for quality assurance of the sterilized product. Some of the problems associated with standardized measurement techniques in radiation sterilization include the choice of dosimetry and its calibration, as well as methods and procedures used to minimize errors due to variations in radiation flux density, source geometry with respect to the product, and environmental factors.

    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 the national and regional institutions. In this study we introduce an outreach index to quantify the impact of borders on the community structure and apply it to the case of the European and US patent co-inventors networks. We find that (a) the US connectivity decays as a power of distance, whereas we observe a faster exponential decay for Europe; (b) European network communities essentially correspond to nations and contiguous regions while US communities span multiple states across the whole country without any characteristic geographic scale. We confirm our findings by means of a set of simulations aimed at exploring the relationship between different patterns of cross-border community structures and the outreach index. PMID:24686380

    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, computerized analysis of dermoscopy images has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. Methods: In this article, we present a systematic overview of the recent border detection methods in the literature paying particular attention to computational issues and evaluation aspects. Conclusion: Common problems with the existing approaches include the acquisition, size, and diagnostic distribution of the test image set, the evaluation of the results, and the inadequate description of the employed methods. Border determination by dermatologists appears to depend upon higher-level knowledge, therefore it is likely that the incorporation of domain knowledge in automated methods will enable them to perform better, especially in ...

  9. Quality control scheme for thyroid related hormones measured by radioimmunoassay

    International Nuclear Information System (INIS)

    A regional quality control scheme for thyroid related hormones measured by radioimmunoassay is being established in the Middle East. The scheme started in January 1985, with eight laboratories which were all from Iraq. At the present nineteen laboratories from Iraq, Jordan, Kuwait, Saudi Arabia and United Arab Emirates (Dubai) are now participating in the scheme. The scheme was supported by the International Atomic Energy Agency. All participants received monthly three freeze dried quality control samples for assay. Results for T3, T4 and TSH received from participants are analysed statistically batch by batch and returned to the participants. Laboratories reporting quite marked bias results were contacted to check the assay performance for that particular batch and to define the weak points. Clinical interpretation for certain well defined samples were reported. A regular case study report is recently introduced to the scheme and will be distributed regularly as one of the guidelines in establishing a trouble shooting programme throughout the scheme. The overall mean between the laboratory performance showed a good result for the T4, moderate but acceptable for T3 and poor for TSH. The statistical analysis of the results based on the concept of a ''target'' value is derived from the believed correct value the ''Median''. The overall mean bias values (ignoring signs) for respectively low, normal and high concentration samples were for T4 18.0 ± 12.5, 11.2 ± 6.4 and 11.2 ± 6.4, for T3 28.8 ± 23.5, 11.2 ± 8.4 and 13.4 ± 9.0 and for TSH 46.3 ± 50.1, 37.2 ± 28.5 and 19.1 ± 12.1. The scheme proved to be effective not only in improving the overall performance but also it helped to develop awareness of the need for internal quality control programmes and gave confidence in the results of the participants. The scheme will continue and will be expanded to involve more laboratories in the region. Refs, fig and tabs

Two years later, on 31 July 1974, the Robbins tunnel-boring machine excavating the SPS tunnel returned to its starting point (see photograph). It had excavated a tunnel with a circumference of 7 kilometres, at an average depth of 40 metres below the surface. The tunnel straddled the Franco-Swiss border, making the SPS the first cross-border accelerator. More than a thousand magnets were needed to equip the ring. The civil engineering and installation work was completed in record time after only four years. The SPS was equipped with a control system which was ahead of its time, consisting of 24 small control computers distributed in the tunnel and the control room and communicating by means of a high-rate data transmission system. The main control room housed only four consoles as opposed to the banks of electronic ...

    Directory of Open Access Journals (Sweden)

    Giuseppe Campesi

    2014-09-01

    Full Text Available The article explores the ambiguous dialectic between the technocratic ideology of risk management and the recurrent call for emergency measures which characterizes Euro-Mediterranean border control policies, showing how Frontex has ultimately succeeded in capitalising on the recurring cry to humanitarian emergencies coming from some Member Countries. Far from seeing its legitimacy undermined as a risk management agency that should predict and prevent potential migratory crisis, it has incorporated the emergency rethoric into its official communication, making it a legitimating tool for a steady expansion of its role, prerogatives and resources to the detriment of alternative actors in migration policy. This reproduces the paradoxes of a humanitarian policy which is intended at protecting the bare life of migrants and asylum seekers, while violating their fundamental rights to escape and find asylum elsewhere.

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

    Directory of Open Access Journals (Sweden)

    Gustavo Dias

    2015-08-01

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

    There are hundreds of people and organizations working on border health issues in the California-Baja California border region trying to protect and improve health. These efforts are being conducted without a collaborative structure that integrates jurisdictions and organizations. Thus, there is a need to coordinate these organizations to work together and benefit from their collective effort and each other's best practices. The outcome of such an effort could effectively improve the health in the border region. The newly developed "California Border Health Collaborative" unites organizations and provides the leadership and collaborative culture to positively improve the health of the border region; it is referred to as the "Collaborative." This article describes the developmental process of this Collaborative, including partner engagement, governance, strategic planning, key elements for success, the roles of multi-level jurisdictions, and policy implications. This paper focuses on describing the preparation and processes that created the U.S./California side of this binational collaborative effort and is a strong reflection of the theory of border collaboration as described by Denman and De Sonora (1) in "Working beyond Borders: A Handbook for Transborder Projects in Health."

    In this thesis, it is intended to benefit from the potential uses of advanced nuclear spectroscopic measurements in both environmental control and non-destructive material testing . It is subdivided into three main chapters including, the introduction, the experimental and the results and related discussions.Chapter-1, the introduction includes in its first part, a number of definitions about toxicity hazards and related damaging effects to our environment, as well as those related to natural radioactivity in different environmental compartments and the different natural radioactive decay series. The second part of this chapter includes sufficient information about the effect of radiation exposure on human health, and the different exposure pathways of radioactive pollutants to man, through atmospheric dispersion, dispersion of radioactivity in liquid effluents, water resources and nutrition materials causing indirect exposure to man. This part also includes a preliminary approach of the major elements in different environmental surveillance programmes, assessment procedures and the different methods mostly used in monitoring radioactivity in food materials, and other environmental samples including water of various resources, different soil, analysis of milk as well as those used in emergency surveys which are mostly referred to when dealing with different types and levels of nuclear accidents

  15. Measuring and test equipment control through bar-code technology

    International Nuclear Information System (INIS)

    Over the past several years, the use, tracking, and documentation of measuring and test equipment (M ampersand TE) has become a major issue. New regulations are forcing companies to develop new policies for providing use history, traceability, and accountability of M ampersand TE. This paper discusses how the Fast Flux Test Facility (FFTF), operated by Westinghouse Hanford Company and located at the Hanford site in Rich- land, Washington, overcame these obstacles by using a computerized system exercising bar-code technology. A data base was developed to identify M ampersand TE containing 33 separate fields, such as manufacturer, model, range, bar-code number, and other pertinent information. A bar-code label was attached to each piece of M ampersand TE. A second data base was created to identify the employee using the M ampersand TE. The fields contained pertinent user information such as name, location, and payroll number. Each employee's payroll number was bar coded and attached to the back of their identification badge. A computer program was developed to automate certain tasks previously performed and tracked by hand. Bar-code technology was combined with this computer program to control the input and distribution of information, eliminate common mistakes, electronically store information, and reduce the time required to check out the M ampersand TE for use

  18. An Automatic Statistical Method to detect the Breast Border in a Mammogram

    Directory of Open Access Journals (Sweden)

    Wai Tak (Arthur Hung

    2007-03-01

    Full Text Available Segmentation is an image processing technique to divide an image into several meaningful objects. Edge enhancement and border detection are important components of image segmentation. A mammogram is a soft x-ray of a woman's breast, which is read by radiologists to detect breast cancer. Recently, digital mammography is also available. In order to do computer aided detection on mammogram, the image has to be either in digital form or digitized. A preprocessing step to a digital/digitized mammogram is to detect the breast border so as to minimize the area to search for breast lesion. An enclosed curve is used to define the breast area. In this paper we propose a modified measure of class separability and used it to select the best segmentation result objectively, which leads to an improved border detection method. This new method is then used to analyze a test set of 35 mammograms. The breast border of these 35 mammograms was also traced manually twice to test for their repeatability using Hung's method1. The borders obtained from the proposed automatic border detection method are shown to be of better quality than the corresponding ones traced manually.

    Recent studies of border effects have focused on the intra-country and inter-country comparison of trade flows. It is found that borders have a negative impact on the size of cross-border trade. In order to estimate border effects on a regional level one needs not only data on inter-country but also on intra-country trade. For many countries (regional) data on intra-country trade are simply lacking, which makes an analysis of border effects and border regions cumbersome. In this paper we take...

    He, Jun; Fallahi, Mahmoud; Norwood, Robert A.; Peyghambarian, Nasser

    2011-06-01

    Wireless sensor networks have been proposed as promising candidates to provide automated monitoring, target tracking, and intrusion detection for border surveillance. In this paper, we demonstrate an ad-hoc wireless sensor network system for border surveillance. The network consists of heterogeneously autonomous sensor nodes that distributively cooperate with each other to enable a smart border in remote areas. This paper also presents energy-aware and sleeping algorithms designed to maximize the operating lifetime of the deployed sensor network. Lessons learned in building the network and important findings from field experiments are shared in the paper.

    Aims and Objectives: The purpose of the study was to determine the effect of border molding on the retention of the maxillary denture base. Materials and Methods: Two special trays, one with full extensions to the periphery and one 2 mm short from the borders were made on the cast obtained from the preliminary impression. Border molding was done on the tray which was short from borders. On both trays, the final impression was made with zinc oxide eugenol impression paste. Heat cure denture bases were fabricated on the prepared casts and retention was measured using specially designed instrument. Observations and Results: Mean force with border molding (2765.0 g) was larger than mean force without border molding (1805.0 g) at P < 0.01 level. In terms of percentage, too, the mean improvement (59.4%) in force of dislodgement was statistically highly significant (i.e. P < 0.01). Clinical Significance: The results of the present study suggest that the dentures made with border molding will provide better retentive force than the dentures made without border molding.

  12. A NEW APPROACH FOR BORDER EXTRACTION USING MORPHOLOGICAL METHODS

    Directory of Open Access Journals (Sweden)

    M Rama Bai

    2010-08-01

    Full Text Available The objective of border detection is to mark the points in a digital image at which the luminous intensity changes sharply. Acute changes in image features usually reflect important events and changes inproperties of the world. These include (a discontinuities in depth (b discontinuities in surface orientation (c changes in material properties and (d variations in scene illumination. A novel algorithm based on multi-scale morphological method for the purpose of border detection is introduced. Standard morphological border detection methods use single and symmetrical structure elements which are used exhaustively in image processing. They could detect the alterations of gray level, but are difficult to detect complex border feature because they are only sensitive to image border which has the same direction of structure elements. A new border detection method based on multi-structure element morphology of eight different directions is proposed. The ability of the proposed detection method is that we get eight different border detection results by using morphological gradient algorithm respectively and final border result is obtained by using synthetic weighted method. The experimental result shows that the proposed algorithm obtains clear and exact borders of the image by retaining the image details and it out performs the conventional morphological border detection algorithms and differential border detection operators. This technique shows the worth of border detection and the ability of detecting sharp complex borders.

  13. Measurement and control of electron-phonon interactions in graphene

    Science.gov (United States)

    Remi, Sebastian

    Despite the weak interaction between electrons and atomic vibrations (phonons) in the one-atom thick crystal of carbon called graphene, the scattering of electrons off phonons limits coherent electron transport in pristine devices over mesoscopic length scales. The future of graphene as a replacement to silicon and other materials in advanced electronic devices will depend on the success of controlling and optimizing electronic transport. In this dissertation, we explore the electron-phonon interaction via Raman scattering, elucidating the effects of filling and emptying charge states on the phonons in both the metallic state and when levels are quantized by an applied perpendicular magnetic field. In zero magnetic field, the phonon energy shifts due to electronic screening by charge carriers. Previously, a logarithmic divergence of the phonon energy was predicted as a function of the charge carrier density. For the first time, we observe signatures of this logarithmic divergence at liquid He temperatures after vacuum annealing on single layers. We also measure the electron-phonon coupling strength, Fermi velocity, and broadening of electronic quantum levels from Raman scattering and correlate these parameters to electronic transport. In a strong perpendicular magnetic field, the energy bands split into discrete Landau levels. Here, we observe kinks and splitting of the optical phonon energy, even when the Landau level transitions are far from resonant with the phonons. We discover that the kinks are attributed to charge filling of Landau levels, as understood from a linearized model based on electron-phonon interactions. Moreover, we show that material parameters determined without magnetic fields also describe phonon behavior in high magnetic fields.

  14. Measuring and controlling the transport of magnetic nanoparticles

    increases with pore diameter. We find that fluxes are faster in aqueous solutions than in hexane, which is attributed to the hydrophilic nature of the porous membranes and differences in wettability. The impact of an applied magnetic flux gradient, which induces magnetization and motion, on permeation is also examined. Surface chemistry plays an important role in determining flux through porous media such as in the environment. Diffusive flux of nanoparticles through alkylsilane modified porous alumina is measured as a model for understanding transport in porous media of differing surface chemistries. Experiments are performed as a function of particle size, pore diameter, attached hydrocarbon chain length and chain terminus, and solvent. Particle fluxes are monitored by the change in absorbance of the solution in the receiving side of a diffusion cell. In general, flux increases when the membranes are modified with alkylsilanes compared to untreated membranes, which is attributed to the hydrophobic nature of the porous membranes and differences in wettability. We find that flux decreases, in both hexane and aqueous solutions, when the hydrocarbon chain lining the interior pore wall increases in length. The rate and selectivity of transport across these membranes is related to the partition coefficient (Kp) and the diffusion coefficient (D) of the permeating species. By conducting experiments as a function of initial particle concentration, we find that KpD increases with increasing particle size, is greater in alkylsilane--modified pores, and larger in hexane solution than water. The impact of the alkylsilane terminus (--CH3, --Br, --NH2, --COOH) on permeation in water is also examined. In water, the highest KpD is observed when the membranes are modified with carboxylic acid terminated silanes and lowest with amine terminated silanes as a result of electrostatic effects during translocation. Finally, the manipulation of magnetic nanoparticles for the controlled formation

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

    Directory of Open Access Journals (Sweden)

    2014-12-01

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

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

    Directory of Open Access Journals (Sweden)

    Dirk Godenau

    2012-05-01

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

    This paper describes a digital radiography (DR) quality control protocol for DR detectors from the forthcoming report from the Institute of Physics and Engineering in Medicine (IPEM). The protocol was applied to a group of six identical caesium iodide (CsI) digital x-ray detectors to assess reproducibility of methods, while four further detectors were assessed to examine the wider applicability. Twelve images with minimal spatial frequency processing are required, from which the detector response, lag, modulation transfer function (MTF), normalized noise power spectrum (NNPS) and threshold contrast-detail (c-d) detectability are calculated. The x-ray spectrum used was 70 kV and 1 mm added copper filtration, with a target detector air kerma of 2.5 µGy for the NNPS and c-d results. In order to compare detector performance with previous imaging technology, c-d data from four screen/film systems were also acquired, at a target optical density of 1.5 and an average detector air kerma of 2.56 µGy. The DR detector images were typically acquired in 20 min, with a further 45 min required for image transfer and analysis. The average spatial frequency for the 50% point of the MTF for six identical detectors was 1.29 mm-1 ± 0.05 (3.9% coefficient of variation (cov)). The air kerma set for the six systems was 2.57 µGy ± 0.13 (5.0% cov) and the NNPS at this air kerma was 1.42 × 10-5 mm2 (6.5% cov). The detective quantum efficiency (DQE) measured for the six identical detectors was 0.60 at 0.5 mm-1, with a maximum cov of 10% at 2.9 mm-1, while the average DQE was 0.56 at 0.5 mm-1 for three CsI detectors from three different manufacturers. Comparable c-d performance was found for these detectors (5.9% cov) with an average threshold contrast of 0.46% for 11 mm circular discs.

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

    International Nuclear Information System (INIS)

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

  8. Imagining and Imaging Borders: Understanding Borderlands for Global Sustainability

    Science.gov (United States)

    Konrad, V.

    2013-11-01

    Borders are increasingly complex human responses and social constructions in a world where globalizing forces confront basic human concerns for security and certainty. In an effort to provide a background to assess research directions for imaging borders, this paper explores what we know about borders, and what we do not know well about borders. Borders in globalization are the meeting points of globalizing forces of security, trade and migration flows with emerging technologies, self determination and regionalization around the world. We need to know more about how: self determination fuels secessions and new borders; borders result from complex rather than simple policy and governance issues; borders depend on the political clout of borderland communities; market and migration flows impact borders; and borders are always in motion. The paper shows how these organizing principles underlie the basic themes of border governance, flows, culture, history, security and sustainability. Finally, the paper offers two brief illustrations of border imaging to link this presentation to the following discussion of the workshop.

    Full Text Available The special clustering algorithm is attractive for the task of grouping arbitrary shaped database into several proper classes. Up to now, a wide variety of clustering algorithms designed for this task have been proposed, the majority of these algorithms is density-based. But the effectivity and efficiency still is the great challenges for these algorithms as far as the clustering quality of such task is concerned. In this paper, we propose an arbitrary shaped clustering method with border grids (PNMBG, PNMBG is a crisp partition method. It groups objects to point neighborhoods firstly, and then iteratively merges these point neighborhoods into clusters via grids, only bordering grids are considered during the merging stage. Experiments show that PNMBG has a good efficiency especially on the database with high dimension. In general, PNMBG outperforms DBSCAN in the term of efficiency and has an almost same effectivity with the later.

    2011-10-01

    Astronomers Without Borders (AWB) brings together astronomy enthusiasts of all types - amateur astronomers, educators, professionals and "armchair" astronomers for a variety of online and physicalworld programs. The AWB web site provides social networking and a base for online programs that engage people worldwide in astronomy activities that transcend geopolitical and cultural borders. There is universal interest in astronomy, which has been present in all cultures throughout recorded history. Astronomy is also among the most accessible of sciences with the natural laboratory of the sky being available to people worldwide. There are few other interests for which people widely separated geographically can engage in activities involving the same objects. AWB builds on those advantages to bring people together. AWB also provides a platform where projects can reach a global audience. AWB also provides unique opportunities for multidisciplinary collaboration in EPO programs. Several programs including The World at Night, Global Astronomy Month and others will be described along with lessons learned.

    2010-09-01

    The remote sensing technology has many practical applications in different fields of science and industry. There is also a need to examine its usefulness for the purpose of land border surveillance. This research started with analysis of potential direct use of Earth Observation technology for monitoring migrations of people and preventing smuggling. The research, however, proved that there are still many fields within which the EO technology needs to be improved. From that point the analysis focused on improving Border Permeability Index which utilizes EO techniques as a source of information. The result of BPI analysis with use of high resolution data provides new kind of information which can support and make more effective work of authorities from security domain.

    2012-10-01

    A two-year old, male entire Border collie was presented with a one-year history of exercise-induced collapsing on the pelvic limbs. Physical examination revealed generalised muscle atrophy. Neurological examination supported a generalised neuromuscular disorder. Electromyography revealed spontaneous electrical activity in almost all muscles. Unfixed and formaldehyde-fixed biopsy samples were collected from the triceps brachii, longissimus and vastus lateralis muscles. Histopathological, histochemical and ultrastructural examinations of biopsy specimens were consistent with either centronuclear or myotubular myopathy. The dog clinically improved with supportive treatment with L-carnitine, co-enzyme Q10 and vitamin B compound. To the authors' knowledge, this is the first report of centronuclear/myotubular myopathy in a Border collie. PMID:23013377

  19. The Nature and Functions of European Political Borders

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

    Auler; Neukater; Franz; Krebs

    2000-07-01

    Large amounts of dismantled materials from nuclear power plants show such a weak level of radioactivity that they could be released after decision measurements. Till some years ago, the decision measurements taken for the release were based only on determining the mass-specific activity of samples by means of gamma spectrometry and/or manual sequential measurements of the surface activity with large area gas flow counters. The choice of an appropriate measuring method, the layout of the release measurement facility (RMF), the way of preparing the material and the development of smart release procedures are very important for a large throughput and an economic performance of the release process. NIS and RADOS have developed RMF based on gross gamma activity. The NIS-RMFs have been applied for the last 10 years for decision measurements in different operated but also in dismantled nuclear power plants. Together with RMFs from RADOS, more than 12,000 Mg of various types of materials have been measured up to now with this method in Germany. PMID:10879881

    This color infrared view of the Chiapas Forest, Mexico and Guatemala border (17.0N, 92.0W) illustrates the usefulness of this type of film in determining vegetated vs non vegetated areas. As can be seen, most of this part of Guatemala remains in closed canopy woodland (dark red), while most of the Mexican land to the north has been cleared for pasture and farmland (pink). The pale green areas north of the river are bare soil or fallow fields.

    The aim of this paper is to propose the notion of culture as a symbolic moving border. Departing from both, Boesch's (1991) concept of culture as a symbolic field of action, and Herbst's (1995) co-genetic logic, I will discuss the dynamics of self-other relationships in terms of their potentiality as sources of movement in culture. A brief analysis of an empirical material is given in illustrative character of the ideas here exposed. PMID:26245862

    This article considers how chauvinistic welfare policies operate as a bordering practice. Taking the UK as an example, it examines a process in which welfare provisions have increasingly been withdrawn from a group of people designated as undeserving. It points out a close link between chauvinism based on ethnicity and based on class. This relation is explored in detail for the case of social housing culminating in today’s “social housing for local people” approach. A second case, access t...

  11. Cultural Borders in an Autobiographical Narrative

    Directory of Open Access Journals (Sweden)

    Tiiu Jaago

    2012-12-01

    Full Text Available This article examines the life story of a woman born in a village in southern Estonia in 1918. It is based on two life stories told in Estonian and one told in Russian, as well as a story about her home. The stories were written at the initiative of the researcher between 1996 and 2004 and are stored in public archives. These texts have been chosen in that they are characteristic of the multifaceted phenomenon of inter-cultural contact: the narrator is of Estonian descent; she was imprisoned during the German occupation and taken to Germany, where she lived among local Germans and Red Army soldiers after the war; she married a man of Russian descent who served in the Red Army; from 1948, she and her family lived in a culturally diverse environment in Kohtla-Järve. The focus of this research is on the manifestation of cultural borders at the levels of life history, self-description and cultural context. The narrator presents herself as a person who is not constrained by cultural borders. The relative importance of various cultures in her life and her self-perception is dependent on the general historical and political context and the context of everyday life at the stage of her life that is being described. This aspect emphasises the flexible and volatile nature of cultural borders; however, the analysis of the text reveals the permanence of cultural borders – the narrator cannot step out of her cultural background when describing a culture that she sees as ‘other’.

    2010-10-01

    Full Text Available Soil pollution results from the build up of contaminants, toxic compounds, radioactive materials, salts, chemicals and cancer-causing agents. The most common soil pollutants are hydrocarbons, heavy metals (cadmium, lead, chromium, copper, zinc, mercury and arsenic, herbicides, pesticides, oils, tars, PCBs and dioxins. Soil Electrical Conductivity (EC is one of the soil physical properties w hich have a good relationship with the other soil characteristics. As measuring soil electrical conductivity is easier, less expensive and faster than other soil properties measurements, using a detector that can do on the go soil EC measurements is a good tool for obtaining useful information about soil pollution condition.

    2011-11-01

    Neuronal ceroid lipofuscinosis (NCL) constitutes a group of recessively inherited lysosomal storage diseases that primarily affect neuronal cells. Such diseases share certain clinical and pathologic features in human beings and animals. Neuronal ceroid lipofuscinosis in Border Collie dogs was first detected in Australia in the 1980s, and the pathogenic mutation was shown to be a nonsense mutation (c.619C>T) in exon 4 in canine CLN5 gene. In the present study, novel rapid genotyping assays including polymerase chain reaction (PCR)-restriction fragment length polymorphism, PCR primer-induced restriction analysis, mutagenically separated PCR, and real-time PCR with TaqMan minor groove binder probes, were developed. The utility of microchip electrophoresis was also evaluated. Furthermore, a genotyping survey was carried out in a population of Border Collies in Japan using these assays to determine the current allele frequency in Japan, providing information to control and prevent this disease in the next stage. All assays developed in the current study are available to discriminate these genotypes, and microchip electrophoresis showed a timesaving advantage over agarose gel electrophoresis. Of all assays, real-time PCR was the most suitable for large-scale examination because of its high throughput. The genotyping survey demonstrated that the carrier frequency was 8.1%. This finding suggested that the mutant allele frequency of NCL in Border Collies is high enough in Japan that measures to control and prevent the disease would be warranted. The genotyping assays developed in the present study could contribute to the prevention of NCL in Border Collies. PMID:22362793

  18. Measuring Effectiveness of Persuasive Games Using an Informative Control Condition

    Directory of Open Access Journals (Sweden)

    Mara Soekarjo

    2015-06-01

    Full Text Available Research about the effectiveness of persuasive games is still emerging. This article presents a literature review of studies that empirically evaluate the effectiveness of persuasive games. The review concluded that limited empirical evidence is currently available to prove their effectiveness in attitude change. It further revealed that almost no study employed an informative control condition, making it difficult to conclude that the game was more effective than a control condition. Next, in a pretest-posttest design an empirical study tested whether change in attitude was different for people playing the persuasive game "EnerCities" compared to a control condition where participants read a document with highly similar information. No significant differences in increase of attitude or knowledge between participants that played the game and participants in the informative control condition were found. Based on the results of the literature review and the empirical study presented, it hence cannot be concluded that playing a game leads to a greater change in attitude or knowledge acquisition than experiencing conventional media would. Future work should employ designs with proper control conditions and focus on which game features lead to significant effects.

    In tactile scanning profiler, the measuring force would change in a wide range when it was used for profile measurement in a large range, which could possibly destroy the measured surface. To solve the problem, measuring force control system for tactile scanning profiler was needed. In the paper, a voice coil motor-based measuring force control system for tactile scanning profiler was designed. In the design, a low stiffness coefficient spring was used to provide contact force, while a voice coil motor (VCM) to balance the spring force so that the contact force could be kept for constant measuring force. A VCM was designed specially, and for active measuring force control, a precision current source circuit under the control of a DSP unit was designed to drive the VCM. The performance of voice coil motor based measuring force control system had been tested, and its good characteristics were verified.

  6. Assessing Measurement Noise Effect in Run-to-Run Process Control: Extends EWMA Controller by Kalman Filter

    Tzu-Wei Kuo

    2011-09-01

    Full Text Available Recently, the Exponentially Weighted Moving Average (EWMA controller has become a popular control method in Run-to-Run (RtR process control, but the issue of measurement noise from metrology tools has not been addressed in RtR EWMA controllers yet. This paper utilizes a Kalman Filter (KF controller to deal with measurement noise in RtR process control and investigates the output properties for steady-state mean and variance, and for closed-loop stability. Five disturbance models modeling semiconductor process disturbances are investigated. These disturbance models consist of Deterministic Trend (DT, Random Walk with Drift (RWD, Integrated Moving Average process (IMA(1,1, AutoRegressive Moving Average (ARMA(1,1, and Autoregressive Integrated Moving Average (ARIMA(1,1,1.  Analytical results show that a KF controller can be considered as an extended version of a RtR EWMA controller. In particular, the EWMA controller is a special case of KF in a filtering form without the capability of measuring noise. Simulation results also show that the KF has a better ability to deal with measurement noise than the EWMA controller.

    Territorial subdivisions and geographic borders are essential for understanding phenomena in sociology, political science, history, and economics. They influence the interregional flow of information and cross-border trade and affect the diffusion of innovation and technology. However, it is unclear if existing administrative subdivisions that typically evolved decades ago still reflect the most plausible organizational structure of today. The complexity of modern human communication, the ease of long-distance movement, and increased interaction across political borders complicate the operational definition and assessment of geographic borders that optimally reflect the multi-scale nature of today's human connectivity patterns. What border structures emerge directly from the interplay of scales in human interactions is an open question. Based on a massive proxy dataset, we analyze a multi-scale human mobility network and compute effective geographic borders inherent to human mobility patterns in the United States. We propose two computational techniques for extracting these borders and for quantifying their strength. We find that effective borders only partially overlap with existing administrative borders, and show that some of the strongest mobility borders exist in unexpected regions. We show that the observed structures cannot be generated by gravity models for human traffic. Finally, we introduce the concept of link significance that clarifies the observed structure of effective borders. Our approach represents a novel type of quantitative, comparative analysis framework for spatially embedded multi-scale interaction networks in general and may yield important insight into a multitude of spatiotemporal phenomena generated by human activity.

  10. Changing European borders: from separation to interface? An introduction

    Directory of Open Access Journals (Sweden)

    Jen Nelles

    2011-03-01

    Full Text Available The aim of this special issue is to address the evolution of European borders from a comparative perspective. This collection of papers spans a wide variety of topics in the realm of borderland studies. Although each engages with a single empirical or theoretical case collectively they identify nuances relevant to the theoretical elaboration of borders, and particularly contribute to the field of sub-national cross-border cooperation. In the course of its analysis each paper contributes to a broader understanding of the definition of cross-border regions; identifies a set of barriers to cooperation in these contexts; explores the role of identities on cooperation and of the role of borders in constructing those identities; and reflects on the socio-political meanings and uses of these international boundaries. This introduction discusses theoretical significance of these contributions to major debates in the study of borders and border regions.

  11. Left ventricular border recognition using a dynamic search algorithm

    International Nuclear Information System (INIS)

    Initial results obtained with a simple, fully automated algorithm for detection of left ventricular boundaries are presented. The strength of this approach is the use of dynamic programming search techniques, which allow determination of local border points to be influenced by the entire global border location. The relative contributions of mask mode subtraction and the dynamic search technique are evaluated with respect to accurate border definition. These computer-determined ventricular borders are compared with hand-traced borders on subtracted and unsubtracted images. The modular dynamic search algorithm is shown to perform better than previously described algorithms, which generally require operator interaction. It is also shown that for both manual and automated techniques, ventricular borders derived from subtracted images may be significantly different from borders derived from nonsubtracted images

This book addresses multiple issues on advanced innovative methods of multi-level control of both ground (UGVs) and aerial drones (UAVs). Those objects combined with innovative algorithms become autonomous objects capable of patrolling chosen borderland areas by themselves and automatically inform the operator of the system about potential place of detection of a specific incident. This is achieved by using sophisticated methods of generation of non-collision trajectory for those types of objects and enabling automatic integration of both ground and aerial unmanned vehicles. The topics included in this book also cover presentation of complete information and communication technology (ICT) systems capable of control, observation and detection of various types of incidents and threats. This book is a valuable source of information for constructors and developers of such solutions for uniformed servi...

  13. Impacts of cement industries on environment and control measure

    International Nuclear Information System (INIS)

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

    Level monitoring instrumentation is an essential part of hydrocarbon processing facilities, and has, together with separator technology, been widely addressed over the last decade. Key issues are production capacity, product enhancement, and well-flow control. The reliability and accuracy of the level instrumentation, and its ability to monitor all the interface layers of the separator, including the thickness of the foam and the oil-water emulsion, are particularly important when considering the level instrumentation as the main sensing element in the automatic control of the separator vessel. Lately, industry focus has been placed on optimal automatic control to improve the quality of the production output, and to minimize the use of expensive and environmentally undesirable separation enhancing chemicals. Recent developments in hydrocarbon production include subsea separation stations, where the constraints placed on the reliability and accuracy of the level instrumentation are especially demanding. This paper presents level interface monitoring developments based on electrical, ultrasonic, thermal, and nucleonic physical principles for three-phase hydrocarbon separators, and introduces the notion of tomometry, meaning multi-point cross-sectional metering aiming to acquire information on the cross-sectional flow-component distribution in the process vessel intended for control purposes.

    Wireless sensor networks (WSNs) have emerged as means of providing automated monitoring, target tracking, and intrusion detection. Solar-powered WSNs that adopt innovative sensors with low power consumption and forefront networking technologies can provide rapidly deployable situational awareness and effective security control at the border at low cost. In our paper, we introduce the prototype of our new solar-powered WSN platform for Border Security. We consider practical issues in WSNs, including sensing environment classification, survivability under harsh weather conditions, and efficient solar energy harvesting. Experimental results demonstrate the performance of our new solar-powered WSN.

    The article deals with the new opportunities for EU member state citizens to go abroad for medical treatment. The European Court of Justice has facilitated the access to medical treatment for EU citizens in other EU states. This development has worried national governments since they feared reduced control in their healthcare systems. The cross-border project "healthacross" between Austria and the Czech Republic however illustrates in which way authorities can respond to patients needs in two different countries. Nevertheless a plethora of administrative and practical problems have to be solved for cross-border co-operation in the provision of healthcare. PMID:21391444

  18. Microprocessor: controlled extensometer for fuel cladding strain measurements

    International Nuclear Information System (INIS)

    An instrument for measuring strain of cladding for nuclear fuels has been developed for use during in-core characterization tests of candidate materials. Employing a microwave sensor of coaxial geometry, a strain of several microinches can be detected. At the opposite extreme, the large dynamic range of the instrument permits measuring strain equal to ten percent of the original specimen dimension. In all configurations tested, the sensor comprises a hollow metal cylinder enclosing a test specimen positioned coaxially within the cylinder. Microwave energy is absorbed by the specimen/sensor unit at particular frequencies related to size of the specimen. Consequently, determination of specimen size results from measurement of the resonant absorption frequencies of the sensor

  20. Analytical estimation of control rod shadowing effect for excess reactivity measurement of HTTR

    International Nuclear Information System (INIS)

    The fuel addition method is generally used for the excess reactivity measurement of the initial core. The control rod shadowing effect for the excess reactivity measurement has been estimated analytically for High Temperature Engineering Test Reactor (HTTR). 3-dimensional whole core analyses were carried out. The movements of control rods in measurements were simulated in the calculation. It was made clear that the value of excess reactivity strongly depend on combinations of measuring control rods and compensating control rods. The differences in excess reactivity between combinations come from the control rod shadowing effect. The shadowing effect is reduced by the use of plural number of measuring and compensating control rods to prevent deep insertion of them into the core. The measured excess reactivity in the experiments is, however, smaller than the estimated value with shadowing effect. (author)

  1. Examining hidden coercion at state borders: why carrier sanctions cannot be justified

    Directory of Open Access Journals (Sweden)

    Tendayi Bloom

    2014-05-01

    Full Text Available Sanctions placed upon airlines and other operators transporting persons without the required paperwork are called ‘carrier sanctions’. They constitute a key example of how border control mechanisms are currently being outsourced, privatized, delegated, and moved from the border itself to new physical locations. These practices can lead to a phenomenon referred to in this paper as ‘hidden coercion’. This paper argues that, while hidden coercion is commonplace in the reality of migration policy in most states, it is so far neglected in theoretical discussions of state coercion. Moreover, the discussion of carrier sanctions demonstrates that this neglect is problematic, since hidden coercion is not justifiable even within a framework that legitimizes state border coercion.

    2012-01-01

    Full Text Available Borders and border areas require security measures, which are very important to create security on the borders. The paper also analyzes the role of ethnic groups living near borderlines. Iran is an ethnically varied country and distinguishing characteristics of ethnic groups from each other in Iran is particularly concentrated on language, religion and ethnic components. These ethnic groups have been scattered as certain minority groups in border provinces and areas. The presence of Iranian nationals in the Western, Eastern and Northern borders which are contiguous with countries with the same religion and language creates by itself an appropriate context for the occurrence of ethnic crises in border areas and boundary underdevelopment is an another cause for this problem. In addition, the three components, namely religion, ethnicity, and language, should be taken into consideration in adopting policies and strategies to deal with these areas. In Sistan and Baluchestan, Iran, there are effective national strategies taking advantage of the presence and existence of religious and ethnic groups in the border towns, adopting security and development policies taking into account these two issues. They have a deep effect on regional development and national solidarity due to construction activities and infrastructure investments on the one hand and reducing insecurity and trafficking on the other hand.

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

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

    International Nuclear Information System (INIS)

    Up to June 1974 areas in Uganda totalling 8600km2 have been successfully reclaimed from tsetse fly infestation by ground spray of 3% dieldrin water emulsions. A search for equally effective but less persistent and toxic compounds against tsetse flies has been unsuccessful. Fourteen insecticide formulations have been tested for their persistence on tree bark surfaces and, therefore, their availability and toxicity to the target tsetse flies. Only those compounds with a high immediate insecticidal activity (some higher than dieldrin) like endosulfan, Chlorfenvinphos and propoxur could merit further consideration in tsetse control. While some were toxic to tsetse as fresh deposits, they lacked sufficient persistence. A study of the environmental implication from the continued use of the highly persistent and toxic dieldrin has provided useful data on residues likely to be found both in terrestrial and aquatic fauna and flora. These are generally low. Moreover, there is evidence of degradation in some fish species (Protopterus aethiopicus and Clarias). Also, dilution factors and adsorption involving the muddy nature of water run-off, etc., and controlled burning of grasses after tsetse eradication would tend to inactivate the residual insecticide and protect aquatic systems. The general findings have indicated less risk than anticipated of the environmental contamination from tsetse control by application of persistent and toxic insecticides. (author)

    Political borders are controversial and contested spaces. In an attempt to better understand movement along and through political borders, this project applied the metaphor of a membrane to look at how people, ideas, and things ''move'' through a border. More specifically, the research team employed this metaphor in a system dynamics framework to construct a computer model to assess legal and illegal migration on the US-Mexico border. Employing a metaphor can be helpful, as it was in this project, to gain different perspectives on a complex system. In addition to the metaphor, the multidisciplinary team utilized an array of methods to gather data including traditional literature searches, an experts workshop, a focus group, interviews, and culling expertise from the individuals on the research team. Results from the qualitative efforts revealed strong social as well as economic drivers that motivate individuals to cross the border legally. Based on the information gathered, the team concluded that legal migration dynamics were of a scope we did not want to consider hence, available demographic models sufficiently capture migration at the local level. Results from both the quantitative and qualitative data searches were used to modify a 1977 border model to demonstrate the dynamic nature of illegal migration. Model runs reveal that current US-policies based on neo-classic economic theory have proven ineffective in curbing illegal migration, and that proposed enforcement policies are also likely to be ineffective. We suggest, based on model results, that improvement in economic conditions within Mexico may have the biggest impact on illegal migration to the U.S. The modeling also supports the views expressed in the current literature suggesting that demographic and economic changes within Mexico are likely to slow illegal migration by 2060 with no special interventions made by either government.

  1. Temporal measures and controls in ultrafast laser domain

    International Nuclear Information System (INIS)

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

    A series of experiments demonstrating that on-line measurements of intracellular NADH by culture fluorescence can be used to monitor and control the fermentation process are described. A distinct advantage of intercellular NADH measurements over other monitoring techniques such as pH and dissolved oxygen is that it directly measures real time events occurring within the cell rather than changes in the environment. When coupled with other measurement parameters, it can provide a finer degree of sophistication in process control.

    2000-10-01

    Current control methods for the black carpenter ant, Camponotus pennsylvanicus (De Geer), include the use of remedial and preventative residual sprays as well as toxic baits. We evaluated the acceptance of three baits (Maxforce, Niban, and Baygon) to field colonies of the black carpenter ant in the spring and fall. Maxforce bait granules were more readily accepted than either Niban or Baygon bait granules in the spring. A change in food preference from protein to sugar by the black carpenter ant appeared to reduce the number of Maxforce bait granules removed in the fall, resulting in no differences in bait acceptability. The longevity of Dursban 50W and Tempo 20WP were evaluated in the summer and fall on painted wood panels. Panels aged outside for 15 d under prevailing weather conditions exhibited increased LT50 values. For each sampling period, panels aged on the south face (in the sun) exhibited less insecticidal activity (i.e., large LT50 values) than panels on the north face (shaded; small LT50 values). At each sampling period, Tempo 20WP provided smaller LT50 values than Dursban 50W. Because of changing dietary preferences, our data highlight the importance of using various bait types for carpenter ant control. Moreover, the application of residual spays should be made to locations protected from direct sunlight. PMID:11057723

Energy resolution, spatial resolution, temporal resolution sensitivity, uniformity, linearity, center of rotation and multi window energy registration were performed according to NEMA standards. In addition to the above mentioned tests MTF was obtained for various collimators of both systems. Apart from the linearity and uniformity of ADAC system which were unacceptable and later were corrected by the company engineers, all the above factors were within acceptable range for both systems. Comparison of MLF curves at various frequencies for SOPHA HEGP collimator and ADAC HEAP collimator shows superior performance of SOPHA system using this collimator

  11. Abrasion measuring method for rod of control rod assembly of reactor

    International Nuclear Information System (INIS)

    The present invention provides a method of easily measuring abrasion caused on the outer surface of control rods of a control assembly to be used in a PWR type reactor. Namely, the control rod assembly comprise a plurality of control rods assembled in a cluster-like manner. Light is irradiated to a control rod to be measured from an optical measuring device for measuring the extent of abrasion on the surface of the control rods. The distance is measured by receiving the reflected light. The depth of abrasion is determined by comparing the thus measured distance to the abraded portion and the distance to an integral portion. Then, the depth of the abrasion is adjusted based on the control rod position and the angle to determine final depth of abrasion. The abrasion of control rods can be measured by remote control using one kind of light sensor. The device can be reduced in the size and the time for the measuring operation can also be shortened.

  12. Nuclear materials control and accountability criteria for upgrades measures

    International Nuclear Information System (INIS)

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

    We model simultaneous inter and within identity-group conflict in two territories connected by cross-territorial spill-overs. Within each territory, two groups contest the division of a group-specific public good, and all members contest the division of group income. Each group has a cross-border affiliate. Greater success (share) of its affiliate 'spills over' into higher efficiency of a group in inter-group conflict. We find that inter-group and total conflict move together within a territo...

    At the end of the year 2006, France proposed the introduction of a 'climatic tariff' into the discussion of the international climatic protection. The 'climatic tariff' shall adjust extra costs, which result from the domestic production by means of environmental protection instruments and to which the import goods are not exposed, with import/export compensatory payments in the form of import duties and/or taxes on import goods. The introduction of an import/export compensatory payment system aims to load imported goods equivalent to domestic products in order to adjust competitive disadvantages. In the contribution under consideration the authors report on possibilities and problems of design for an import/export tax compensatory. The authors examine the validity of the measures of import/export compensation from legal view the World Trade Organization (Geneva, Switzerland) based on the General Agreement on Tariffs and Trade.

    The NSF Nanomanufacturing Program supports fundamental research in novel methods and techniques for batch and continuous processes, and top-down and bottom-up processes leading to the formation of complex nanostructures, nanodevices and nanosystems. The program leverages advances in the understanding of nano-scale phenomena and processes, nanomaterials discovery, novel nanostructure architectures, innovative nanodevice and nanosystem design. It seeks to address issues such as quality, efficiency, scalability, reliability, safety and affordability. The program encourages research in the development of new nano-scale processes and production systems based on computation, modeling and simulation and use of process sensing, monitoring, and control. Research in instrumentation and metrology is an integral part of the program. Additionally, the program supports education of the next generation of researchers, and encourages building a workforce trained in nanotechnology and nanomanufacturing systems. It is also interested in understanding long-term societal implications of large-scale production and use of nano-scale materials. For this, it encourages the development of standards. This paper will describe the program philosophy.

  16. Fact and fiction in ECP measurement and control

    International Nuclear Information System (INIS)

    A review is presented of various electrochemical potentials, including the electrochemical corrosion potential, ECP, and the redox potential (Eredox) that are used in describing corrosion processes that occur in aqueous systems and for controlling and mitigating stress corrosion cracking in the primary coolant circuits of nuclear power reactors (primarily BWRs). Attention is paid to carefully defining each potential in terms of fundamental electrochemical concepts, so as to counter the confusion that has arisen amongst practitioners and theorists alike, due to the misuse of previously accepted terminology. A brief discussion is also included of reference electrodes and it is shown that the use of a platinum redox sensor as a reference electrode in the monitoring of ECP in BWR primary coolant circuits is inappropriate unless it is demonstrated to yield a potential that is invariant with changes in the composition of the medium. Data from laboratory experiments in simulated BWR coolant and model calculations argue that the potential of the Pt redox sensor is not invariant with respect to composition under the conditions that exist in BWR pressure vessels and hence the use of a Pt sensor as a reference electrode is inappropriate.

    Globally, rotavirus diarrhea results in 453,000 deaths in children younger than 5 y—37% of deaths attributable to diarrhea and 5% of all deaths in children younger than 5 y. India alone accounts for 22% (~100,000 deaths) of all deaths attributable to rotavirus infection. Two oral rotavirus vaccines are available: Rotarix, a monovalent P1A[8] G1 vaccine (GlaxoSmithKline), and RotaTeq, a pentavalent bovine-human reassortant vaccine (Merck). Rotarix is administered in a 2-dose schedule with the first and second doses of DTP (DTP1, DTP2). RotaTeq requires a 3-dose schedule with DTP1, DTP2 and DTP3 with an interval of 4–10 weeks between doses. The first dose of either vaccine should be administered to infants aged 6–15 weeks irrespective of the history of previous rotavirus infection, and the maximum age for administering the last dose of either vaccine should be 32 weeks. Although India would require funding from international health organizations/GAVI until new indigenous rotavirus vaccine candidates are developed at a cheaper price, introduction of vaccination into the national immunization program would be a cost-effective step toward control of the rotavirus diarrhea-related morbidity and mortality in India.

    Full Text Available The article investigates the challenging task of governing cross-border investment in peripheral regions. The main objective is to identify common opportunities and obstacles in the Pomerania Euroregion by taking the case study of Polish citizens/ entrepreneurs investing in northeast Germany. This relatively new phenomenon is accompanied by large uncertainties and risks, and lacks further empirical insights. At the same time it breaks new ground, creates alternatives, calls for the development of efficient modes of cross-border cooperation and addresses mutual governance issues on an inter-regional basis between manifold stakeholders on both sides of the border. The case study summarises findings from fieldwork, elaborates a quantitative and qualitative assessment of cross-border governance measures within formal and informal institutions, and tries to formulate policy recommendations for prospective approaches
