Methodology: A web-based search was conducted to identify learning resources meeting defined inclusion criteria with a particular focus on the resources available in the Western Canadian provinces. Information was extracted using a standardized template, and we contacted IEHP programs for additional information if necessary. Members of the research team reviewed preliminary findings, identified missing information from their respective provinces, and contacted organizations to fill in any gaps. Results: The scan identified 26 learning resources for IEHPs in Western Canadian provinces and 15 in other provinces focused on support for IEHPs to meet their profession-specific licensing requirements and to acquire knowledge and competencies relevant to working in the Canadian health care system. Most learning resources, such as those found in bridging programs for IEHPs, included an orientation to the Canadian health care system, components of cultural competence, and at least one aspect of interprofessional competence (eg, communication skills. None of the 41 learning resources provided comprehensive training for IEHPs to cover the six interprofessional competency

  4. Are environmental scanning units effective?

    Science.gov (United States)

    Stubbart, C

    1982-06-01

    Many authorities have urged companies to set up environmental scanning to assist corporate planning. Some advocates have recommended a unit at corporate level. This would give breadth of view and penetration into the future. It would arm decision makers with accurate forecasts. The information would be broad in scope and future directed. It could provide also assumptions for long-range planning. The Fahey and King study produced a model of corporate scanning types. The data showed that environmental information was built into the plan. Though the political environment was important, scanning was inadequate. The best location for scanning was not at corporate level and most firms used irregular methods. The Thomas study concluded that effective environmental scanning was permanent and multi level and that 'best practice' was continuous scanning. In 1978 the sample organizations were revisited. Five of the twelve have not changed their practice. The factors which encouraged a continuous model were the attitudes of academics and business media, demonstrated success of the units, the right kind of personnel. Contrary influences were changes in top management, decentralization moves, resource cuts, defining the environment and its significance, the availability of scanning competent personnel, surprise itself, and the availability of alternatives e.g. external forecasts.

    Full Text Available This paper identifies and analyses the factors internal to the organization, which affect the activity of environmental scanning, understood here as the information seeking activity of managers, directed at the company's external environment. These factors include individual factors, such as information consciousness and exposure to information, and organizational factors such as information climate and "outwardness". The main relationships among them are also analysed. These factors were identified in the course of research aiming to provide a comprehensive understanding of the environmental scanning process (Correia & Wilson, 1996. The methodology used - a case-study approach coupled with the grounded theory method of qualitative analysis - was of major importance in obtaining information that is grounded largely on the personal experience of managers.

  13. Environmental scanning as information seeking and organizational learning

    Directory of Open Access Journals (Sweden)

    2001-01-01

    Full Text Available Environmental scanning is the acquisition and use of information about events, trends, and relationships in an organization's external environment, the knowledge of which would assist management in planning the organization's future course of action. Depending on the organization's beliefs about environmental analyzability and the extent that it intrudes into the environment to understand it, four modes of scanning may be differentiated: undirected viewing, conditioned viewing, enacting, and searching. We analyze each mode of scanning by examining its characteristic information needs, information seeking, and information use behaviours. In addition, we analyze organizational learning processes by considering the sensemaking, knowledge creating and decision making processes at work in each mode.

    We empirically investigate the responsiveness of international trade to the stringency of environmental regulation. Stringent environmental regulation may impair the export competitiveness of 'dirty' domestic industries, and as a result, 'pollution havens' emerge in countries where environmental regulation is 'over-lax.' We examine the impact of pollution abatement and control costs on net exports in order to grasp this phenomenon. Theoretically, our analysis is related to a general equilibrium model of trade and pollution nesting the pollution haven motive for trade with the factor endowment motive. We analyze data on two-digit ISIC manufacturing industries during the period 1977-1992 in Germany, the Netherlands and the US, and show that trade patterns in 'dirty' commodities are jointly determined by relative factor endowments and environmental stringency differentials.

  15. Internal scanning method as unique imaging method of optical vortex scanning microscope

    Popiołek-Masajada, Agnieszka; Masajada, Jan; Szatkowski, Mateusz

    2018-06-01

    The internal scanning method is specific for the optical vortex microscope. It allows to move the vortex point inside the focused vortex beam with nanometer resolution while the whole beam stays in place. Thus the sample illuminated by the focused vortex beam can be scanned just by the vortex point. We show that this method enables high resolution imaging. The paper presents the preliminary experimental results obtained with the first basic image recovery procedure. A prospect of developing more powerful tools for topography recovery with the optical vortex scanning microscope is discussed shortly.

    2015-01-01

    A transmission environmental scanning electron microscope with use of a scintillation gaseous detection device has been implemented. This corresponds to a transmission scanning electron microscope but with addition of a gaseous environment acting both as environmental and detection medium. A commercial type of low vacuum machine has been employed together with appropriate modifications to the detection configuration. This involves controlled screening of various emitted signals in conjunction with a scintillation gaseous detection device already provided with the machine for regular surface imaging. Dark field and bright field imaging has been obtained along with other detection conditions. With a progressive series of modifications and tests, the theory and practice of a novel type of microscopy is briefly shown now ushering further significant improvements and developments in electron microscopy as a whole. - Highlights: • Novel scanning transmission electron microscopy (STEM) with an environmental scanning electron microscope (ESEM) called TESEM. • Use of the gaseous detection device (GDD) in scintillation mode that allows high resolution bright and dark field imaging in the TESEM. • Novel approach towards a unification of both vacuum and environmental conditions in both bulk/surface and transmission mode of electron microscopy

SLEAF is a new generation of laser fluorosensor designed to provide prompt reliable detection and mapping of oil pollution in different marine and terrestrial environments. It consists of a high-power excimer laser, high-resolution range-gated intensified diode-array spectrometer, and a pair of variable speed and angular displacement scanning mirrors. SLEAF is capable of detecting narrow bands of oil that can pile up along the high tide lines of beaches and shorelines, including those that contain ice and snow. It also has the added benefit of providing real-time detection. SLEAF will be declared operational for emergency response personnel when the initial test flight program will be completed in the near future. 9 refs., 2 figs

  6. Challenges imposed by International Environmental Law to Classical International Law

    2010-05-01

    Full Text Available The emergence of international environmental law has produced important challenges to the very foundations of public international law. Traditional concepts such as state sovereignty, subjects of international law, and the early perspectives of national security are being transformed. The needs of the contemporary international society differ from the ones of the Wesphalian conception, situations which clearly explains the raise of alternative views for the understanding of the current dynamics of international law, where concepts like res communis, common concerns and simply “commons” take a privileged place in the study of international law. The foregoing has been strengthened by the international development of the so called erga ommnes obligations, label which is being used by international environmental law as the perfect explanation of its own existence. This academic article presents and studies the abovementioned concepts trying to compare what international law used to be before the emergence of international environmental law and what it is and what it should be in order to attend the developments and challenges imposed by the contemporary international society, particularly by international environmental law, a new fi eld of the corpus juris of public international law.

    Problems and opportunities frequently cross national borders. Informal and formal international arrangements-loosely termed regimes, defined in this paper as systems of rule or government that have widespread influence-arise for the collective management of such transboundary issues. Regimes are pervasive; their number and extent have grown markedly in the 20th century, especially since the Second World War. Students of the international system study the conditions under which regimes are formed and the factors that contribute to their success. These include distribution of power among states, the nature of the issue, its linkages to other issues, the roles and functions of international organizations, the processes of bargaining and rule-making, and the influence of domestic politics. Scholars also theorize how regimes are maintained and changed. In the past two decades students of international cooperation have increasingly applied their tools to issues of the environment and natural resources

    The exploration of remote planetary surfaces calls for the advancement of low power, highly-miniaturized instrumentation. Instruments of this nature that are capable of multiple types of analyses will prove to be particularly useful as we prepare for human return to the moon, and as we continue to explore increasingly remote locations in our Solar System. To this end, our group has been developing a miniaturized Environmental-Scanning Electron Microscope (mESEM) capable of remote investigations of mineralogical samples through in-situ topographical and chemical analysis on a fine scale. The functioning of an SEM is well known: an electron beam is focused to nanometer-scale onto a given sample where resulting emissions such as backscattered and secondary electrons, X-rays, and visible light are registered. Raster scanning the primary electron beam across the sample then gives a fine-scale image of the surface topography (texture), crystalline structure and orientation, with accompanying elemental composition. The flexibility in the types of measurements the mESEM is capable of, makes it ideally suited for a variety of applications. The mESEM is appropriate for use on multiple planetary surfaces, and for a variety of mission goals (from science to non-destructive analysis to ISRU). We will identify potential applications and range of potential uses related to planetary exploration. Over the past few of years we have initiated fabrication and testing of a proof-of-concept assembly, consisting of a cold-field-emission electron gun and custom high-voltage power supply, electrostatic electron-beam focusing column, and scanning-imaging electronics plus backscatter detector. Current project status will be discussed. This effort is funded through the NASA Research Opportunities in Space and Earth Sciences - Planetary Instrument Definition and Development Program.

    Muon tomography is a potential non-invasive technique for internal structure scanning. It has already interesting applications in geophysics and can be used for archaeological purposes. Muon tomography is based on the measurement of the muon flux after crossing the structure studied. Differences on the mean density of these structures imply differences on the detected muon rate for a given direction. Based on this principle, Monte Carlo simulations represent a useful tool to provide a model of the expected muon rate and angular distribution depending on the composition of the studied object, being useful to estimate the expected detected muons and to better understand the experimental results. These simulations are mainly dependent on the geometry and composition of the studied object and on the modelling of the initial muon flux at surface. In this work, the potential of muon tomography in archaeology is presented and evaluated with Monte Carlo simulations by estimating the differences on the muon rate due to the presence of internal structures and its composition. The influence of the chosen muon model at surface in terms of energy and angular distributions in the final result has been also studied.

Results of research show that the beginning of the XXI century is distinguished by the development of new types of political concepts that explain interaction of elements in modern international relations in the area of environmental protection. The reason of these changes lies in the phenomena of environmentalism integration into Three paradigms of international relations. However, we cannot say that any of the examined paradigms accumulated all features of environmentalism without their modification. Better to say, it's rather similar to adaptation of environmental ideas. Therefore, to understand modern international relations processes, it is necessary to take into account their environmental element. Purchase on Elibrary.ru > Buy nowDOI: http://dx.doi.org/10.12731/2070-7568-2014-3-4

  17. Probing Individual Ice Nucleation Events with Environmental Scanning Electron Microscopy

    2016-04-01

    Heterogeneous ice nucleation is one of the processes of critical relevance to a range of topics in the fundamental and the applied science and technologies. Heterogeneous ice nucleation initiated by particles proceeds where microscopic properties of particle surfaces essentially control nucleation mechanisms. Ice nucleation in the atmosphere on particles governs the formation of ice and mixed phase clouds, which in turn influence the Earth's radiative budget and climate. Heterogeneous ice nucleation is still insufficiently understood and poses significant challenges in predictive understanding of climate change. We present a novel microscopy platform allowing observation of individual ice nucleation events at temperature range of 193-273 K and relative humidity relevant for ice formation in the atmospheric clouds. The approach utilizes a home built novel ice nucleation cell interfaced with Environmental Scanning Electron Microscope (IN-ESEM system). The IN-ESEM system is applied for direct observation of individual ice formation events, determining ice nucleation mechanisms, freezing temperatures, and relative humidity onsets. Reported microanalysis of the ice nucleating particles (INP) include elemental composition detected by the energy dispersed analysis of X-rays (EDX), and advanced speciation of the organic content in particles using scanning transmission x-ray microscopy with near edge X-ray absorption fine structure spectroscopy (STXM/NEXAFS). The performance of the IN-ESEM system is validated through a set of experiments with kaolinite particles with known ice nucleation propensity. We demonstrate an application of the IN-ESEM system to identify and characterize individual INP within a complex mixture of ambient particles.

    This paper investigates the determinants of nations' commitment to environmental protection at the international level by focusing on the role of national intelligence and the level of democracy. The national intelligence is measured by nation's IQ scores. The findings based on a sample of 152 nations provide strong evidence that intelligence has statistically significant impact on ratification of international environmental agreements, and the countries with IQ 10-points above global average are 23% more likely to sign multilateral environmental agreements than others. The findings also demonstrate that it is the combination of high-level of intelligence of nations and democracy, that likely result in international environmental commitments.

  19. Internalizing Externalities through Payments for Environmental Services

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Forest ecosystems, including plantation forests, provide goods and services that are marketable and non-marketable. Positive externalities produced by forest ecosystems are rarely considered in pricing of marketable products that result in economic inefficiencies. Internalizing externalities is required to improve the economic efficiency. The traditional way to internalize an externality is by providing subsidies or imposing taxes. Recently, payments for environmental services  are receiving more attention as an instrument for internalizing externalities provided by forest ecosystems. This promising alternative to improve our environment needs to be studied more extensively. In this paper, it can be indicated theoretically that the Pigovian tax, as a traditional way of addressing environmental problems, is able to mimic the result derived from the employment of environmental services payment. The difference is that environmental services payment improves the welfare of environmental service producers, whereas the Pigovian tax reduces it. A positive Pigovian tax increases the optimal rotation, which is positively associated with environmental improvement, but certainly reduces forest owner's welfare. This difference should be taken into account in the public policymaking so that perverse incentive may be avoided. Payment for environmental services  as an additional income to forest growers, not as alternative source of income, is a potential tool to address simultaneously issues of environment and poverty that are frequently contested.Keywords: externalities, payments for environmental services, tax, perverse incentive, social welfare

  20. Measuring the effectiveness of international environmental regimes

    1999-05-01

    While past research has emphasized the importance of international regimes for international governance, systematic assessments of regime effects are missing. This article derives a standardized measurement concept for the effectiveness of international environmental regimes by developing an operational rational choice calculus to evaluate actual policy simultaneously against a non-regime counterfactual and a collective optimum. Subsequently, the empirical feasibility of the measurement instrument is demonstrated by way of two international treaties regulating transboundary air pollution in Europe. The results demonstrate that the regimes indeed show positive effects - but fall substantially short of the collective optima. (orig.)

    We performed a directed environmental scan to identify and categorize quality indicators unique to critical care that are reported by key stakeholder organizations. We convened a panel of experts ( n = 9) to identify key organizations that are focused on quality improvement or critical care, and reviewed their online publications and website content for quality indicators. We identified quality indicators specific to the care of critically ill adult patients and then categorized them according to the Donabedian and the Institute of Medicine frameworks. We also noted the organizations' rationale for selecting these indicators and their reported evidence base. From 28 targeted organizations, we identified 222 quality indicators, 127 of which were unique. Of the 127 indicators, 63 (32.5%) were safety indicators and 61 (31.4%) were effectiveness indicators. The rationale for selecting quality indicators was supported by consensus for 58 (26.1%) of the 222 indicators and by published research evidence for 45 (20.3%); for 119 indicators (53.6%), the rationale was not reported or the reader was referred to other organizations' reports. Of the 127 unique quality indicators, 27 (21.2%) were accompanied by a formal grading of evidence, whereas for 52 (40.9%), no reference to evidence was provided. There are many quality indicators related to critical care that are available in the public domain. However, owing to a paucity of rationale for selection, supporting evidence and results of implementation, it is not clear which indicators should be adopted for use.

  3. Environmental policies in an international mixed duopoly

    Science.gov (United States)

    Ferreira, Fernanda A.; Ferreira, Flávio

    2009-11-01

    The purpose of this paper is to study the effects of environmental and trade policies in an international mixed duopoly serving two markets. We suppose that the firm in the home country is a welfare-maximizing public firm, while the firm in the foreign country is its own profit-maximizing private firm. We find that the environmental tax can be a strategic instrument for the home government to distribute production from the foreign private firm to the home public firm. An additional effect of the home environmental tax is the reduction of the foreign private firm's output for local consumption, thereby expanding the foreign market for the home public firm.

    Full Text Available This paper analysis international regulation of the precautionary principle as one of environmental principles. This principle envisages that when there are threats of serious and irreparable harm, as a consequence of certain economic activity, the lack of scientific evidence and full certainty cannot be used as a reason for postponing efficient measures for preventing environmental harm. From economic point of view, the application of precautionary principle is problematic, because it creates larger responsibility for those who create possible risks, comparing to the previous period. The precautionary principle can be found in numerous international treaties in this field, which regulate it in a very similar manner. There is no consensus in doctrine whether this principle has reached the level of international customary law, because it was interpreted differently and it was not accepted by large number of countries in their national legislations. It represents a developing concept which is consisted of changing positions on adequate roles of science, economy, politics and law in the field of environmental protection. This principle has been discussed in several cases before International Court of Justice and International Tribunal for the Law of the Sea.

  9. Paying for international environmental public goods.

    Arriagada, Rodrigo; Perrings, Charles

    2011-11-01

    Supply of international environmental public goods must meet certain conditions to be socially efficient, and several reasons explain why they are currently undersupplied. Diagnosis of the public goods failure associated with particular ecosystem services is critical to the development of the appropriate international response. There are two categories of international environmental public goods that are most likely to be undersupplied. One has an additive supply technology and the other has a weakest link supply technology. The degree to which the collective response should be targeted depends on the importance of supply from any one country. In principle, the solution for the undersupply lies in payments designed to compensate local providers for the additional costs they incur in meeting global demand. Targeted support may take the form of direct investment in supply (the Global Environment Facility model) or of payments for the benefits of supply (the Payments for Ecosystem Services model).

  10. Analysis of DOE international environmental management activities

    Energy Technology Data Exchange (ETDEWEB)

    Ragaini, R.C.

    1995-09-01

    The Department of Energy`s (DOE) Strategic Plan (April 1994) states that DOE`s long-term vision includes world leadership in environmental restoration and waste management activities. The activities of the DOE Office of Environmental Management (EM) can play a key role in DOE`s goals of maintaining U.S. global competitiveness and ensuring the continuation of a world class science and technology community. DOE`s interest in attaining these goals stems partly from its participation in organizations like the Trade Policy Coordinating Committee (TPCC), with its National Environmental Export Promotion Strategy, which seeks to strengthen U.S. competitiveness and the building of public-private partnerships as part of U.S. industrial policy. The International Interactions Field Office task will build a communication network which will facilitate the efficient and effective communication between DOE Headquarters, Field Offices, and contractors. Under this network, Headquarters will provide the Field Offices with information on the Administration`s policies and activities (such as the DOE Strategic Plan), interagency activities, as well as relevant information from other field offices. Lawrence Livermore National Laboratory (LLNL) will, in turn, provide Headquarters with information on various international activities which, when appropriate, will be included in reports to groups like the TPCC and the EM Focus Areas. This task provides for the collection, review, and analysis of information on the more significant international environmental restoration and waste management initiatives and activities which have been used or are being considered at LLNL. Information gathering will focus on efforts and accomplishments in meeting the challenges of providing timely and cost effective cleanup of its environmentally damaged sites and facilities, especially through international technical exchanges and/or the implementation of foreign-development technologies.

  11. Environmental and social footprints of international trade

    Science.gov (United States)

    Wiedmann, Thomas; Lenzen, Manfred

    2018-05-01

    Globalization has led to an increasing geospatial separation of production and consumption, and, as a consequence, to an unprecedented displacement of environmental and social impacts through international trade. A large proportion of total global impacts can be associated with trade, and the trend is rising. Advances in global multi-region input-output models have allowed researchers to draw detailed, international supply-chain connections between harmful production in social and environmental hotspots and affluent consumption in global centres of wealth. The general direction of impact displacement is from developed to developing countries—an increase of health impacts in China from air pollution linked to export production for the United States being one prominent example. The relocation of production across countries counteracts national mitigation policies and may negate ostensible achievements in decoupling impacts from economic growth. A comprehensive implementation of the United Nations Sustainable Development Goals therefore requires the inclusion of footprint indicators to avoid loopholes in national sustainability assessments.

    A litany of dismal happenings - global warming, ozone layer depletion, desertification, destruction of biodiversity, acid rain, and nuclear and water accidents - are but some of the subjects covered by this book, a problem-solving casebook authored by three educators. This new book makes the obvious but important point, that environmental issues are not limited by national boundaries. The book is divided into three parts. The first three chapters of part I discuss the basic principals of traditional international law without any reference to environmental issues. Part II, comprised of seven chapters, deals with hypothetical problems that affect various aspects of the environment vis-a-vis the norms, institutions, and procedures through which the international legal system operates. The book concludes with two chapters dealing with future environmental concerns. The book focuses on issue-spotting, problem-solving, and synthesis over the assimilation and comprehension of raw, disembodied knowledge. The book helps to manage our common future on this planet, for which we will need a new global regime based essentially on the extension into international life of the rule of law, together with reliable mechanisms for accountability and enforcement that provide the basis for the effective functioning of national societies

  13. Understanding the development of international environmental agreements

    Stærdahl, Jens

    There are many different theoretical schools concerned with how international regimes develop, and each supplies its own interpretation focusing on one or a few aspects of the process. Such ‘one shot’ explanations may be fruitful for scientific debate, but less useful as conceptual frameworks...... for practitioners and planners manoeuvring in a complex world. On the basis of a review of selected theories of international and environmental regulation, this article initiates the development of a conceptual framework for understanding the development of internationalenvironmental agreements. The point...... of departure for developing the model is the actor-structure debate within social science and theory of international relations. Based on critical realism, a framework is developed specifying the relation between collective action problem situations and negotiation situations. It is argued that the main...

  14. Programmatic Environmental Scans: A Survey Based on Program Planning and Evaluation Concepts

    Directory of Open Access Journals (Sweden)

    Donna J. Peterson

    2015-10-01

    Full Text Available Within Extension, environmental scans are most commonly used to assess community or organizational issues or for strategic planning purposes. However, Extension has expanded the use of environmental scans to systematically identify “what programs exist” on a given topic or focus area. Yet, despite recent attention to the topic of environmental scanning in Extension, survey instruments used to conduct environmental scans have not been published. Given the emphasis on implementation of evidence-based practices and programs, having a ready-made survey that can be used to identify programs on a specific topic and that could subsequently lead to an evaluability assessment of those programs would be a useful resource. To encourage the use of environmental scans to identify existing evidence-based programs, this article describes a survey instrument developed for the purpose of scanning for 4-H Healthy Living programs ready for rigorous outcome evaluation and/or national replication. It focuses on the rationale for survey items, as well as provides a summary and definition of those items. The survey tool can be easily adapted for future programmatic environmental scans both within and outside Extension.

    Full Text Available Abstract The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape. Polyvinyl siloxane impressions and Type IV gypsum models were also obtained and scanned with a benchtop laboratory scanner (3Shape D700. Ten zirconia copings were fabricated for each group using CAD-CAM technology. The marginal and internal fit of the zirconia copings was assessed by the silicone replica technique. Four sections of each replica were obtained, and each section was evaluated at four points: marginal gap (MG, axial wall (AW, axio-occlusal edge (AO and centro-occlusal wall (CO, using an image analyzing software. The data were submitted to one-way ANOVA and Tukey’s test (α = 0.05. They showed statistically significant differences for MG, AO and CO. Regarding MG, intraoral scanning showed lower gap values, whereas gypsum model scanning showed higher gap values. Regarding AO and CO, intraoral digital scanning showed lower gap values. Polyvinyl siloxane impression scanning and gypsum model scanning showed higher gap values and were statistically similar. It can be concluded that intraoral digital scanning provided a lower mean gap value, in comparison with conventional impressions and gypsum casts scanned with a standard benchtop laboratory scanner.

    Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening

    Ulph, A.; Maddison, D.

    1997-01-01

    In this paper we construct a simple model of global warming which captures a number of key features of the global warming problem: (1) environmental damages are related to the stock of greenhouse gases in the atmosphere; (2) the global commons nature of the problem means that these are strategic interactions between the emissions policies of the governments of individual nation states; (3) there is uncertainty about the extent of the future damages that will be incurred by each country from any given level of concentration of greenhouse gases but there is the possibility that at a future date better information about the true extent of environmental damages may become available; an important aspect of the problem is the extent to which damages in different countries may be correlated. In the first part of the paper we consider a simple model with two symmetric countries and show that the value of perfect information is an increasing function of the correlation between damages in the two countries in both the cooperative and non-cooperative equilibria. However, while the value of perfect information is always non-negative in the cooperative equilibrium, in the non- cooperative equilibrium there is a critical value of the correlation coefficient below which the value of perfect information will be negative. In the second part of the paper we construct an empirical model of global warming distinguishing between OECD and non-OECD countries and show that in the non-cooperative equilibrium the value of perfect information for OECD countries is negative when the correlation coefficient between environmental damages for OECD and non-OECD countries is negative. The implications of these results for international agreements are discussed. 3 tabs., 26 refs

  2. Issues management - Internet in environmental scanning. A strategic weapon or just another fancy toy? (situation in Finland)

    1998-01-01

    The objective of the study is to find out how different international industrial companies in Finland use the Internet as a tool in the environmental scanning process and in issues management as well. Is Internet used at all in this respect? Prime target is to find an easy way to monitor future developments via Internet and in that sense be able to forecast the future issues and develop the process of issues management. The study is descriptive and its purpose is not to shake walls but realistically describe Internet's scanning possibilities in everyday life. Communication managers in eight different Finnish companies were interviewed. Issues management and environmental scanning are parts of an organisation's strategic planning. Strategic plans are not available even for academic researchers unless the results of the study are kept secret. The level of the results of this study is therefore practical and simplistic. This chapter tells briefly some of the results gained from research. It seems that at least big forest companies use Internet a lot but because of the strategic matters involved they did not reveal all their scanning details. In general it seems that communication managers in Finland don't yet use all the available possibilities that the Internet can offer to the process of environmental scanning. Internet is still quite a new tool. Traditional information gathering techniques are still more appreciated, for instance personal contacts with environmental activists are highly valued and a common way to get information about the future events. The culture of environmental activism in Finland has moved towards quite an open direction recently. Activists can call the companies' information personnel to let them know that they are going to demonstrate in the backyard of a company and invite international press to film the show - the actions are open. There are some militant groups, however, that operate differently and hints about their actions and current

    Investigating the hygroscopic behavior of haze aerosol particles is essential for understanding their physicochemical properties and their impacts on regional weather and visibility. An environmental scanning electron microscope equipped with a home-made transmission-scattering electron imaging setup and an energy dispersive spectrometer was used for in-situ observations of pure water-soluble (WS) salts and Beijing haze particles. This imaging setup showed obvious advantages for improving the resolution and acquiring internal information of mixed particles in hydrated environments. We measured the deliquescence relative humidity of pure NaCl, NH4NO3, and (NH4)2SO4 by deliquescence-crystallization processes with an accuracy of up to 0.3% RH. The mixed haze particles showed hygroscopic activation like water uptake and morphological changes when they included WS components such as nitrates, sulfates, halides, ammoniums, and alkali metal salts. In addition, the hygroscopic behavior provides complementary information for analyzing possible phases in mixed haze particles.

    On lifting a heavy case, a 51-year-old male experienced a sudden onset of headache with giddiness and clouded vision. A week later, vertigo and right hand numbness were added to his symptoms. The next day anisocoria (right > left) and dilation of the left retinal veins were noted. Cranial computed tomography (CT) scan appeared normal and there were no other remarkable neurological findings. The patient was treated conservatively for cerebral infarction, however, the headache worsened and diplopia occurred. Neurological examination on admission revealed nothing unusual except for left Horner's syndrome. Physical examination showed a palpable sausage-like painless tumor on the left side of the neck. Angiography showed a narrowing of the internal carotid artery in the cervical region with a small dissecting aneurysm at the C3 level. Cervical CT scan at the upper C3 level showed a low density lunar defect in the high density section of the enlarged left internal carotid artery. The patient was operated on by superficial temporal artery-middle cerebral artery anastomosis to increase the intracranial blood flow. Postoperatively the symptoms were quickly relieved. Angiography 1 month later showed less narrowing of the carotid artery, though the dissecting aneurysm still remained. Postoperative cervical CT scan showed the left internal carotid artery to be of normal size. The patient returned to his work in normal condition 2 months later. It is emphasized that cervical CT scan may be useful in the diagnosis of this unusual type of cervical dissecting aneurysm.

    This in vitro study compared the tooth color and the ultrastructure of internal dental tissues before and after internal bleaching. Sodium perborate was placed in the pulp chamber of endodontically treated molars and sealed with intermediate restorative material. The test samples were stored in a physiologic solution, and the bleaching agent was replaced every 7 days. A control group was used. After 1 month, the colors of the test and control samples were measured with a colorimeter, and the internal surfaces were observed under field emission scanning electron microscopy (FESEM). Statistically significant differences were found between the test and control sample colors. The FESEM ultrastructure analysis of the internal enamel and dentin surfaces did not show any changes after the internal bleaching. The results of the present study show that sodium perborate is effective in bleaching nonvital teeth and does not produce ultrastructural changes in the dental tissues.

    2014-01-01

    This paper presents the findings of a systematic review of scholarly publications that report empirical findings from studies of environmentally-related international migration. There exists a small, but growing accumulation of empirical studies that consider environmentally-linked migration that spans international borders. These studies provide useful evidence for scholars and policymakers in understanding how environmental factors interact with political, economic and social factors to influence migration behavior and outcomes that are specific to international movements of people, in highlighting promising future research directions, and in raising important considerations for international policymaking. Our review identifies countries of migrant origin and destination that have so far been the subject of empirical research, the environmental factors believed to have influenced these migrations, the interactions of environmental and non-environmental factors as well as the role of context in influencing migration behavior, and the types of methods used by researchers. In reporting our findings, we identify the strengths and challenges associated with the main empirical approaches, highlight significant gaps and future opportunities for empirical work, and contribute to advancing understanding of environmental influences on international migration more generally. Specifically, we propose an exploratory framework to take into account the role of context in shaping environmental migration across borders, including the dynamic and complex interactions between environmental and non-environmental factors at a range of scales.

    Middeke, A.

    1994-01-01

    In consideration of the awful ecological situation, the further development of environmental protection is the task of the Community institutions and the individual member states. The environmentalists advance this improvement by increasingly setting further protectionist measures within their power, such as those already existing in other member states or those community established. The legally motivated environment protection measures of individual member states could create a non-tariff trade barrier between member states; business and industry situated there must adapted to the environmental conditions of the particular member state, if they wish to launch their product in that state. These safeguard clauses, concerning environmental law are of different nature, are thoroughly analysed and systematized by the author. The thesis gives priority to Article 100A, paragraph 4 and 5, and to Article 130T or 130R, paragraph 2, subparagraph 2, which has recently been introduced by the Treaty of Maastricht for the European Union. These articles are represented concerning their substantive and adjective requirements and are critically reviewed. Problems that have arisen in the course of the review are dealt with dogmatically and are discussed at length. The problems of national discrimination and the consideration of fundamental rights in the Community law are treated as well as the mixture of competences in the environmental law of the Community or the options on legal protection against national environmental acts, which can be made use of by Community institutions and by member states.

    1993-01-01

    Transboundary environmental problems with their far-reaching consequences impinge on vital interests of the affected countries. As states interdepend not only ecologically but also, or even primarily, economically, environmental problems usually engender a clash between ecological and economic interests. Although economic power is central to getting one's way, economically powerful states by no means always succeed in realising their aims. This topical monograph deals with the subject of regional and global debates and conflicts about transboundary environmental problems. The author points out the prerequisites for realising ecological interests in conditions of complex interdependence, illustrating his findings with two case studies. One is about the establishment of a regime for climate protection, while the other concerns the new ruling on transalpine commercial road transport. (orig./HP) [de

    Full Text Available The “environmental crisis” we experience today and the international community’s struggle to develop environmental standards to reach the epic “sustainable development” are widely known topics. What is needed, then, is an urgent and determined practice, which is only possible if international governance is structured, coherent and effective. The optimization of Environmental Multilateralism (the joining of what are considered the “driving forces” of Environmental International Relations: Law, Politics and international Diplomacy contributes greatly to this end. To understand its basic concepts and systems, as for example, its actors, negotiation and implementation of Multilateral Environmental Agreements (MEAs and the carrying out of their Regimes, as well as their development in the United Nations, these are all crucial elements for its improvement and optimization. The United Nations Conference on Environment and Development (Rio de Janeiro, 1992 and “its” Conventions are important examples in the history of Environmental Multilateralism, still very up-to-date not only due to the 20th anniversary of the “Rio Conference” but also due to the continuity and importance that the “Rio Conventions” and their Conferences of Parties (COP still have. This papers aims to analyze this area of studies transversal to International Relations and to the Environment, namely by studying the relation between the theory of Environmental Multilateralism and its practice.

    (1) To provide other organizations with useful information when implementing paediatric navigation programs and (2) to inform the implementation of a navigation care centre in New Brunswick for children with complex health conditions. This environmental scan consisted of a literature review of published and grey literature for paediatric patient navigation programs across Canada. Additional programs were found following discussions with program coordinators and navigators. Interviews were conducted with key staff from each program and included questions related to patient condition; target population and location; method delivery; navigator background; and navigator roles. Data analysis included analysis of interviews and identification of common themes across the different programs. We interviewed staff from 19 paediatric navigation programs across Canada. Programs varied across a number of different themes, including: condition and disease type, program location (e.g., hospital or clinic), navigator background (e.g., registered nurse or peer/lay navigator) and method of delivery (e.g., phone or face-to-face). Overall, navigator roles are similar across all programs, including advocacy, education, support and assistance in accessing resources from both within and outside the health care system. This scan offers a road map of Canadian paediatric navigation programs. Knowledge learned from this scan will inform stakeholders who are either involved in the delivery of paediatric patient navigation programs or planning to implement such a program. Specifically, our scan informed the development of a navigation centre for children with complex health conditions in New Brunswick.

    Sever posterior epistaxis is one of the serious clinical problems. Nasal bleeding usually occurs in the anterior septal region, where it can be seen easily and controlled with topical cautery or localized packing. When the bleeding occurs in the posterior nose, it becomes a more serious problem. Many methods have been used to control posterior epistaxis. Some of these are electrocautery, posterior nasal packing, vascular ligation and therapeutic percutaneous embolization. Between 1997 and 2000, nineteen patients were admitted to our hospital because of intractable epistaxis. There were 16 male and 3 female patients whose average age was 55 years. Ten of 19 patients were hypertensive, and none of these had undergoing treatment. Five of 19 patients received maxillary artery ligation. Clinical applications of 3D imaging of the internal maxillary artery using helical CT scan were done for 5 patients. These images were helpful for planning of ligation of the internal maxillary artery. (author)

    International Environmental Agreements (IEAs) are a form of cooperation ratified by countries which can improve the management of shared environmental resources. The authors analyze the stability of International Environmental Agreements in leadership model. In 2006, Diamantoudi & Sartzetakis found that a stable coalition consists of either 2, 3, or 4 members if the number of countries is greater than 4. Their model is reconsidered. It is shown that the size of stable IEAs decreases from 3 to 2 when the total number of countries involved increases. However, a situation that can guarantee 4 to be the size of stable IEAs could not be found.

    We present an alternative approach to realize structured illumination microscopy (SIM), which is capable for live cell imaging. The prototype utilizes two sets of scanning galvo mirrors, a polarization converter and a piezo-platform to generate a fast shifted, s-polarization interfered and periodic variable illumination patterns. By changing the angle of the scanning galvanometer, we can change the position of the spots at the pupil plane of the objective lens arbitrarily, making it easy to switch between widefield and total internal reflection fluorescent-SIM mode and adapting the penetration depth in the sample. Also, a twofold resolution improvement is achieved in our experiments. The prototype offers more flexibility of pattern period and illumination orientation changing than previous systems.

    Prenatal screening tests for Down syndrome (DS) are routine in many developed countries and new tests are rapidly becoming available. Decisions about prenatal screening are increasingly complex with each successive test, and pregnant women need information about risks and benefits as well as clarity about their values. Decision aids (DAs) can help healthcare providers support women in this decision. Using an environmental scan, we aimed to identify publicly available DAs focusing on prenatal screening/diagnosis for Down syndrome that provide effective support for decision making. Data sources searched were the Decision Aids Library Inventory (DALI) of the Ottawa Patient Decision Aids Research Group at the Ottawa Health Research Institute; Google searches on the internet; professional organizations, academic institutions and other experts in the field; and references in existing systematic reviews on DAs. Eligible DAs targeted pregnant women, focused on prenatal screening and/or diagnosis, applied to tests for fetal abnormalities or aneuploidies, and were in French, English, Spanish or Portuguese. Pairs of reviewers independently identified eligible DAs and extracted characteristics including the presence of practical decision support tools and features to aid comprehension. They then performed quality assessment using the 16 minimum standards established by the International Patient Decision Aids Standards (IPDASi v4.0). Of 543 potentially eligible DAs (512 in DALI, 27 from experts, and four on the internet), 23 were eligible and 20 were available for data extraction. DAs were developed from 1996 to 2013 in six countries (UK, USA, Canada, Australia, Sweden, and France). Five DAs were for prenatal screening, three for prenatal diagnosis and 12 for both). Eight contained values clarification methods (personal worksheets). The 20 DAs scored a median of 10/16 (range 6-15) on the 16 IPDAS minimum standards. None of the 20 included DAs met all 16 IPDAS minimum standards

This kind of transboundary damages have given rise to theories of State responsibility and a worldwide demand for increased environmental protection. "Under the principles of international law...no State has the right to use or permit the use of its territory in such a manner as to cause [environmental] injury ... in or to the territory of another or the properties of persons therein, when the case is of serious consequence and the injury is established by clear and convincing evidence."

    Full Text Available One of the most important areas of development during the last 15 years, as far as accounting is concerned, has been the environmental reporting and accounting, generating interests beyond the restrictions imposed by purely academic discussions or the professional accountants community. The objective of the paper is represented by the analysis of scientific knowledge and existing practices in the area of environmental reporting. Mathews (1997, 2001 and Parker (2005 are one of the most representative studies that examine the evolution and status of researches in the area of accounting and environmental reporting. Because of the fact that reports offered by the traditional financial accounting system are insufficient for reflecting a clear and complete image of the company's environmantal impact, I monitored the frameworks or mechanisms of environmental information. Also, the paper analysis the articles treating international environmental reporting, articles publised in ISI quoted or BDI indexed journals. The collection and analysis of reporting frames, the interpretation and analysis thereof represent the main instruments used in order to bring to the forefront the main existing reporting frames for environmental information, found at international level. The quantitative, applicative research is used to reflect the current status of researches in the field of environmental reporting, using the non-participative observation to reflect the current status of researches in the field of environmental reporting, by using the non-participative observation, the collection and analysis of articles as main research instruments. The study concludes that environmental reporting continues to represent the main attraction of researchers in the field of environmental accounting. The main reason for researches on environmental reporting is represented by the description, investigation and improvement of practices on accounting and reporting environmental

    Due to its ultrahigh electron transmissivity in a wide electron energy range, molecular impermeability, high electrical conductivity and excellent mechanical stiffness, suspended graphene membranes appear to be a nearly ideal window material for in situ (in vivo) environmental electron microscopy of nano- and mesoscopic objects (including bio-medical samples) immersed in liquids and/or in dense gaseous media. In this paper, taking advantage of a small modification of the graphene transfer protocol onto metallic and SiN supporting orifices, reusable environmental cells with exchangeable graphene windows have been designed. Using colloidal gold nanoparticles (50 nm) dispersed in water as model objects for scanning electron microscopy in liquids as proof of concept, different conditions for imaging through the graphene membrane were tested. Limiting factors for electron microscopy in liquids, such as electron beam induced water radiolysis and damage of the graphene membrane at high electron doses, are discussed.

  14. Theoretical Aspects of Analysis of International Environmental Security

    Juliya A. Rusakova

    2015-01-01

    Full Text Available Abstract: International environmental security is a very hot contemporary issue of world politics, which in a large part defines the future of our environment. Dealing with this issue is of outmost importance since its failure will render all other issues and challenges as negligible. The article examines the theoretical aspects of solving the problem of environmental security. In particular, it analyzes the problem of negative social externalities, and the related concept of "tragedy of the commons." These problems create a fundamental obstacle to the implementation of environmental security at the global level. Traditionally, the problem of externalities in the environmental field have been approached economically, states and their manufacturers were to pay for the externalities in the form of additional taxes. However, experience shows that the economic tools of dealing with environmental security are not effective. The author suggests alternative non-economic approaches: strengthening and developing the system of permanent institutions of international negotiations on environmental security and promotion of environmental awareness. Solving the acute environmental problems is impossible without a change of the political philosophy of the ruling elites in most states.

    Ferromanganese crusts are chemical sedimentary rock composed mainly of iron-manganese oxide. Because the ferromanganese crusts grow very slowly on the sea floor at rates of 3-10 mm/Ma, long-term deep-sea environmental changes can be reconstructed from the ferromanganese crusts. Thus, it is important to provide reliable age model for the crusts. For the past decades 10Be/9Be dating method has been used extensively to give age models for crusts younger than 15 Ma. Alternatively, sub-millimeter scale magnetostratigraphic study on a ferromanganese crust sample using a scanning SQUID (superconducting quantum interference device) microscope (Kawai et al., 2016; Oda et al., 2016) has been applied successfully (e.g. Oda et al., 2011; Noguchi et al. 2017). Also, environmental magnetic mapping was successful for the ferromanganese crust from the Takuyo Daigo Seamount (Noguchi et al., 2017). The ferromanganese crust used in this study was sampled from the Hanzawa Seamount, Ryukyu trench and the Shotoku Seamount. The vertical component of the magnetic field above thin section samples of the ferromanganese crust was measured using the scanning SQUID microscope on 100 μm grids. Magnetic mapping of the Hanzawa Seamount shows sub-millimeter scale magnetic stripes parallel to lamina. By correlating the boundaries of magnetic stripes with known geomagnetic reversals, we estimated that average growth rate of the Hanzawa Seamount is 2.67 +/- 0.04 mm/Ma , which is consistent with that deduced from the 10Be/9Be dating method (2.56 +/- 0.04 mm/Ma). The crust sample from the Shotoku Seamount used by Oda et al. (2011) shows prominent periodical lamination. Further details are going to be discussed together with the environmental magnetic mapping.

    Objectives Culture and religion are important in advance care planning (ACP), yet it is not well understood how this is represented in ACP online resources. The aim of the present study was to identify the availability of Australian-based ACP websites and online informational booklets containing cultural and religious information. Methods An environmental scanning framework was used with a Google search conducted from 30 June 2015 to 5 July 2015. Eligible Australian-based ACP websites and online informational booklets were reviewed by two analysts (APS & PM) for information pertaining to at least one culture or religion. Common characteristics were agreed upon and tabulated with narrative description. Results Seven Australian-based ACP websites were identified with varying degrees of cultural and religious information. Seven Australian-based ACP informational booklets were identified addressing culture or religion, namely of Aboriginal and Torres Strait Islander (n=5), Sikh (n=1) and Italian (n=1) communities. Twenty-one other online resources with cultural and religious information were identified, developed within the context of health and palliative care. Conclusions There is no comprehensive Australian-based ACP website or informational booklet supporting ACP across several cultural and religious contexts. Considering Australia's multicultural and multifaith population, such a resource may be beneficial in increasing awareness and uptake of ACP. What is known about the topic? Health professionals and consumers frequently use the Internet to find information. Non-regulation has resulted in the proliferation of ACP online resources (i.e. ACP websites and online informational booklets). Although this has contributed to raising awareness of ACP, the availability of Australian-based ACP online resources with cultural and religious information is not well known. What does this paper add? This paper is the first to use an environmental scanning methodology to identify

    Ironstones or petroplinthites are common materials in soils under humid tropical climate, generally defined as the result of Fe oxide accumulation in areas where the water table oscillates, and may exhibit considerable morphological variability. The aim of this study was to examine the internal structure and porosity of an ironstone fragment from a Petroferric Acrudox in Minas Gerais, Brazil, by computed tomography (CT) and conventional techniques. The sample analyzed had total porosity of 59.5 %, with large macropores in the form of tubular channels and irregular vughs, the latter with variable degrees of infilling by material released from the ironstone walls or the soil matrix. The CT scan also showed that the ironstone has wide variation in the density of the solid phase, most likely due to higher concentrations or thick intergrowths of hematite and magnetite/maghemite, especially in its outer rims. The implications of these results for water retention and soil formation in ironstone environments are briefly discussed. (author)

    Results are presented of the AERTOs project (Associated European Research and Technology Organisations). The objective is to identify, design and implement joint, long-term, sustainable cooperation activities between RTOs (Research and Technology Organisations). The purpose of this work is a bottom-up approach to develop and deploy joint activities towards a Bio-based Economy. The results of this report will deliver input for a more extensive paper about the position of the RTOs in Europe. This report contains a quick scan of various biomass value chains that could emerge. Together with the AERTOs partners several bio-based chains were selected for further evaluation. Next, the technological, economical and environmental aspects of each step of the production chain were determined. By integrating this data over the full chain, the chains could be compared to each other in a consistent way. A sensitivity analysis then provided insight into the bottlenecks in the value chain.

    Observing reacting single atoms on the solid catalyst surfaces under controlled reaction conditions is a key goal in understanding and controlling heterogeneous catalytic reactions. In-situ real time aberration corrected environmental (scanning) transmission electron microscopy (E(S)TEM permit the direct imaging of dynamic surface and sub-surface structures of reacting catalysts. In this paper in-situ AC ETEM and AC ESTEM studies under controlled reaction environments of oxide catalysts and supported metal nanocatalysts important in chemical industry are presented. They provide the direct evidence of dynamic processes at the oxide catalyst surface at the atomic scale and single atom dynamics in catalytic reactions. The ESTEM studies of single atom dynamics in controlled reaction environments show that nanoparticles act as reservoirs of ad-atoms. The results have important implications in catalysis and nanoparticle studies

    Purpose: In proton radiotherapy, the production of neutrons is a wellknown problem since neutron exposure can lead to increased risk of secondary cancers later in the patient’s lifetime. The assessment of neutron exposure is, therefore, important for the overall quality of proton radiotherapy. This study investigates the secondary neutrons created inside the patient from uniform scanning proton beams. Methods: Dose equivalent due to secondary neutrons was measured outside the primary field as a function of distance from beam isocenter at three different angles, 45, 90 and 135 degree, relative to beam axis. Plastic track nuclear detector (CR-39 PNTD) was used for the measurement of neutron dose. Two experimental configurations, in-air and cylindrical-phantom, were designed. In a cylindrical-phantom configuration, a cylindrical phantom of 5.5 cm diameter and 35 cm long was placed along the beam direction and in an in-air configuration, no phantom was used. All the detectors were placed at nearly identical locations in both configurations. Three proton beams of range 5 cm, 18 cm, and 32 cm with 4 cm modulation width and a 5 cm diameter aperture were used. The contribution from internal neutrons was estimated from the differences in measured dose equivalent between in-air and cylindrical-phantom configurations at respective locations. Results: The measured ratio of neutron dose equivalent to the primary proton dose (H/D) dropped off with distance and ranged from 27 to 0.3 mSv/Gy. The contribution of internal neutrons near the treatment field edge was found to be up to 64 % of the total neutron exposure. As the distance from the field edge became larger, the external neutrons from the nozzle appear to dominate and the internal neutrons became less prominent. Conclusion: This study suggests that the contribution of internal neutrons could be significant to the total neutron dose equivalent.

    The evolution of the environmental aspects of international petroleum exploration and exploitation is outlined. Four case studies of modern petroleum contracts from four developing countries are presented. These are Thailand's modern concession contract, Indonesia's production sharing contract, Brazil's risk service contract and China's hybrid contract. The failure of these four countries to provide adequate environmental regulation through their petroleum contracts is typical of many countries in the developing world. An urgent need exists to recognise that important environmental and resource consequences are associated with the developments authorised by petroleum contracts and that appropriate legal changes must be made to take them into account. Environmental sustainability should be an explicit part of all investment arrangements. (UK)

  7. A compact atomic force-scanning tunneling microscope for studying microelectronics and environmental aerosols

    Chen, G.

    1996-06-01

    This dissertation describes the characteristics and the construction of a compact atomic force/scanning tunneling microscope (AFM/STM). The basics and the method of preparing a tunneling junction between a chemically etched tunneling tip and a micro-manufactured cantilever is outlined by analyzing the forces between tunneling tip and cantilever as well as between force-sensing tip and sample surfaces. To our best knowledge this instrument is the first one using a commercial cantilever with only one piezoelectric tube carrying the whole tunneling sensor. The feedback control system has been optimized after a careful analysis of the electronic loop characteristics. The mode of operation has been determined by analyzing the dynamic characteristics of the scan heads and by investigating the time characteristics of the data acquisition system. The vibration isolation system has been calibrated by analyzing the characteristics of the damping setup and the stiffness of the scan head. The calculated results agree well with the measured ones. Also, a software package for data acquisition and real time display as well as for image processing and three-dimensional visualization has been developed. With this home-made software package, the images can be processed by means of a convolution filter, a Wiener filter and other 2-D FFT filters, and can be displayed in different ways. Atomic resolution images of highly oriented pyrolytic graphite (HOPG) and graphite surfaces have been obtained in AFM and STM mode. New theoretical explanations have been given for the observed anomalous STM and AFM images of graphite by calculating the asymmetric distribution of quantum conductance and tip-surface forces on a graphite surface. This not only resolved the theoretical puzzles of STM and AFM of graphite, but also revealed the relation between atomic force microscopy and scanning tunneling microscopy of graphite. Applications of STM and AFM to micro-electronic devices have been investigated

    Proteus mirabilis is a human pathogen able to form biofilms on the surface of urinary catheters. Little is known about P. mirabilis biofilms on natural or industrial surfaces and the potential consequences for these settings. The main aim of this work was to assess and compare the adhesion and biofilm formation of P. mirabilis strains from different origins on chitin and stainless steel surfaces within 4 to 96 h. Using environmental scanning electron microscopy, the biofilms of a clinical strain grown on chitin at 4 h showed greater adhesion, aggregation, thickness, and extracellular matrix production than those grown on stainless steel, whereas biofilms of an environmental strain had less aggregation on both surfaces. Biofilms of both P. mirabilis strains developed different structures on chitin, such as pillars, mushrooms, channels, and crystalline-like precipitates between 24 and 96 h, in contrast with flat-layer biofilms produced on stainless steel. Significant differences ( p  biofilm formation. This represents the first study of P. mirabilis showing adhesion, biofilm formation, and development of different structures on surfaces found outside the human host.

  9. Environmental protection and international law: the case of nuclear energy

    Given the very hazardous nature of its activity, the nuclear industry has often been considered to be without a future. Concerns over climate change and increasing international energy needs have, however, shone a new light on the positive aspects of nuclear energy. As the only clean, stable and inexpensive energy source, available, nuclear energy promises a constant supply of electricity while protecting the atmosphere. This new relationship between the environment and nuclear energy calls for an analysis of the international regulation of the risks posed by nuclear energy production. Since the beginning of the nuclear age, the long term, unknown, and large geographic scope of the risks and effects of this activity have led to the adoption of a set of normative rules outside of the scope of international environmental law. The norms that now regulate this new, ultra-hazardous activity resulted in a set of rules aimed at protecting the environment in the face of high risk activities that now form the heart of international environmental law. Unwilling relinquish national sovereignty, States adopted a system of non-binding regulation to protect the environment and promote the nuclear industry. The Chernobyl accident later pointed to the weakness of this approach. Despite this weakness, the adoption of a soft law approach has led to progress in environmental protection in an area where States have been loathe to give up their sovereignty. (author)

    In this paper, we study the effects of environmental and trade policies in an international mixed duopoly serving two markets, in which the public firm maximizes the sum of consumer surplus and its profit. We also analyse the effects of privatization. The model has two stages. In the first stage, governments choose environmental taxes and import tariffs, simultaneously. Then, the firms engage in a Cournot competition, choosing output levels for the domestic market and to export. We compare the results obtained in the three different ways of moving on the decision make of the firms.

  11. Incentives to participate in an international environmental agreement

    1997-01-01

    For international environmental problems involving many countries, such as the climate problem, it is unlikely that all countries will participate in an international environmental agreement. If some countries commit themselves to cooperate, while the remaining countries act independently and in pure self-interest, it appears to be possible to achieve a Pareto improvement if the non-signatory countries reduce their emissions, in exchange for transfers from the countries which sign an agreement. However, the paper shows that the prospect of receiving a transfer for reducing one's emissions provided the country does not commit itself to cooperation, tends to reduce the incentive a country might have to commit itself to cooperation. Moreover, if the disincentive effect of such side payments is strong, total emissions will be higher in a situation with side payments than in a situation in which the signatory countries commit themselves to not give transfers to free riding countries. 4 figs., 2 tabs., 2 appendices, 13 refs

    Environmental scanning electron microscopy (ESEM) allows the examination of hydrated and dried specimens without a conductive metal coating which could be advantageous in the imaging of biological and medical objects. The aim of this study was to assess the performance and benefits of wet-mode and low vacuum ESEM in comparison to high vacuum scanning electron microscopy (SEM) using the choroid plexus of chicken embryos as a model, an organ of the brain involved in the formation of cerebrospinal fluid in vertebrates. Specimens were fixed with or without heavy metals and examined directly or after critical point drying with or without metal coating. For wet mode ESEM freshly excised specimens without any pre-treatment were also examined. Conventional high vacuum SEM revealed the characteristic morphology of the choroid plexus cells at a high resolution and served as reference. With low vacuum ESEM of dried but uncoated samples the structure appeared well preserved but charging was a problem. It could be reduced by a short beam dwell time and averaging of images or by using the backscattered electron detector instead of the gaseous secondary electron detector. However, resolution was lower than with conventional SEM. Wet mode imaging was only possible with tissue that had been stabilized by fixation. Not all surface details (e.g. microvilli) could be visualized and other structures, like the cilia, were deformed. In summary, ESEM is an additional option for the imaging of bio-medical samples but it is problematic with regard to resolution and sample stability during imaging. Copyright © 2011 Elsevier GmbH.

  13. International Environmental Agreements with Endogenous or Exogenous Risk

    OpenAIRE

    2014-01-01

    We examine the effect of endogenous and exogenous risk on the equilibrium (expected) membership of an International Environmental Agreement when countries are risk averse. Endogenous risk arises when countries use mixed rather than pure strategies at the participation game, and exogenous risk arises from the inherent uncertainty about the costs and benefits of increased abate- ment. Under endogenous risk, an increase in risk aversion increases expected participation. Under exogenous risk and ...

  14. Response of international shipping to the current environmental challenges

    2016-01-01

    Full Text Available The international shipping industry directly facilitates the growth of the world trade, economic development and improvement of the global living standards. As the world economy and population continue to expand, the volume of maritime trade is expected to increase significantly as well. Maritime transport already contributes significantly to the three pillars of sustainable development – social, environmental and economic. Maritime transportation is generally considered environmental friendly when compared to other transportation means, especially if the energy efficiency is measured per tonne transported/per mile. Nevertheless, emissions from the growing maritime transport sector represent a significant and growing source of air pollution. One of future goals in international shipping is to reduce CO2 emissions. The International Maritime Organization is the United agency responsible for the protection of the environment from the impact of maritime transport. All parts of shipping industry are examining a number of ways to reduce CO2 emissions, which are primarily linked to reducing fuel consumption. The paper identifies the main areas that should be addressed if maritime sustainable development is to be achieved. It presents analysis of activities focused on environmentally friendly solutions as a form of IMO support for realization of the strategy of sustainable development.

    2018-02-01

    Introduction In a 2015 report, the Institute of Medicine (IOM; Washington, DC USA), now the National Academy of Medicine (NAM; Washington, DC USA), stated that the field of Emergency Medical Services (EMS) exhibits signs of fragmentation; an absence of system-wide coordination and planning; and a lack of federal, state, and local accountability. The NAM recommended clarifying what roles the federal government, state governments, and local communities play in the oversight and evaluation of EMS system performance, and how they may better work together to improve care. This systematic literature review and environmental scan addresses NAM's recommendations by answering two research questions: (1) what aspects of EMS systems are most measured in the peer-reviewed and grey literatures, and (2) what do these measures and studies suggest for high-quality EMS oversight? To answer these questions, a systematic literature review was conducted in the PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA), Web of Science (Thomson Reuters; New York, New York USA), SCOPUS (Elsevier; Amsterdam, Netherlands), and EMBASE (Elsevier; Amsterdam, Netherlands) databases for peer-reviewed literature and for grey literature; targeted web searches of 10 EMS-related government agencies and professional organizations were performed. Inclusion criteria required peer-reviewed literature to be published between 1966-2016 and grey literature to be published between 1996-2016. A total of 1,476 peer-reviewed titles were reviewed, 76 were retrieved for full-text review, and 58 were retained and coded in the qualitative software Dedoose (Manhattan Beach, California USA) using a codebook of themes. Categorizations of measure type and level of application were assigned to the extracted data. Targeted websites were systematically reviewed and 115 relevant grey literature documents were retrieved. A total of 58 peer-reviewed articles met inclusion

    The last international features proposed by the Organization for Economic Cooperation Development (OECD) and United Nations (UN) are analyzed in the use of the environmental indicators, in typology, selection criteria, and models, for organizing the information for management, environmental performance, and decision making. The advantages and disadvantages of each model are analyzed, as well as their environmental index characteristics. The analyzed models are Pressure - State - Response (PSR) and its conceptual developments: Driving Force - State Response (DSR), Driving Force - Pressure - State - Impact - Response (DPSIR), Model- Flow-Quality (MFQ), Pressure - State - Impact - Effect - Response (PSIER), and, finally, Pressure-State - Impact - Effect - Response - Management (PSIERM). The use of one or another model will depend on the quality of the available information, as well as on the proposed objectives

    An environmental scan (ES) is an efficient mixed-methods approach to collect and interpret relevant data for strategic planning and project design. To date, the ES has not been used nor evaluated in the clinical cancer genetics setting. We created and implemented an ES to inform the design of a quality improvement (QI) project to increase the rates of adherence to national guidelines for cancer genetic counseling and genetic testing at three unique oncology care settings (OCS). The ES collected qualitative and quantitative data from reviews of internal processes, past QI efforts, the literature, and each OCS. The ES used a data collection form and semi-structured interviews to aid in data collection. The ES was completed within 6 months, and sufficient data were captured to identify opportunities and threats to the QI project's success, as well as potential barriers to, and facilitators of guideline-based cancer genetics services at each OCS. Previously unreported barriers were identified, including inefficient genetic counseling appointment scheduling processes and the inability to track referrals, genetics appointments, and genetic test results within electronic medical record systems. The ES was a valuable process for QI project planning at three OCS and may be used to evaluate genetics services in other settings.

    1987-01-01

    Internal scanning of wood by microwaves presents many advantages for the automatic detection of defects and the evaluation of the characteristics of wood in the dry wood processing industries. Advantages are: access to more than one variable, efficient coupling in the air, easy automation and reasonable cost. Microwaves are electromagnetic waves the speed and attenuation of which depend of the medium in which they are propagated, especially its electric permittivity which depends on its moisture content and its density. Since wood is anisotropic, this dielectric constant also varies with the direction of fibers. An experimental apparatus was set up that allows to test the feasibility of automatic detection of wood characteristics and defects. It automatically measures the attenuation and dephasing of an ultra high frequency wave sent through a board and moving through two rotating antennas. The graphs and results obtained gave significant information of physical characteristics of wood (density, moisture content, slope of grain) and the detection of defects (knots, metallic objects, sapwood)

    Full Text Available Ironstones or petroplinthites are common materials in soils under humid tropical climate, generally defined as the result of Fe oxide accumulation in areas where the water table oscillates, and may exhibit considerable morphological variability. The aim of this study was to examine the internal structure and porosity of an ironstone fragment from a Petroferric Acrudox in Minas Gerais, Brazil, by computed tomography (CT and conventional techniques. The sample analyzed had total porosity of 59.5 %, with large macropores in the form of tubular channels and irregular vughs, the latter with variable degrees of infilling by material released from the ironstone walls or the soil matrix. The CT scan also showed that the ironstone has wide variation in the density of the solid phase, most likely due to higher concentrations or thick intergrowths of hematite and magnetite/maghemite, especially in its outer rims. The implications of these results for water retention and soil formation in ironstone environments are briefly discussed.

    To determine the number of patients considered not appropriate to approach for assent within the first 24 hours of PICU admission. Exploratory prospective 1-month environmental scan. Two tertiary Canadian PICUs. Ninety patients age newborn to 17 years old admitted to the PICU during September 2016 (Site 1) or May 2017 (Site 2). None. At PICU admission, 81% of patients were deemed not appropriate to approach for assent most commonly due to age, influence of psychotropic medications, and/or mechanical ventilation. At PICU discharge, 74% of patients were considered not appropriate to approach, most commonly due to age and/or developmental delay. There was moderate to good agreement between the research team and care team assessments of appropriateness for assent. Only 8% of patients considered not approachable at admission become appropriate to approach for assent by PICU discharge. Very few patients were considered approachable for assent during the first 24 hours of PICU admission. Those who were considered appropriate to approach were less ill, spent less time in PICU, and were unlikely to be considered for enrollment in pediatric critical care research.

    Environmental Scanning Electron Microscopy (ESEM) is used to study the origin of micro-crack healing in an Engineered Cementitious Composite (ECC). ESEM images were acquired from ECC specimens cut from pre-cracked, dog-bone samples which then subjected to submerged curing followed by exposure to the natural environment. The mineralogical and chemical compositions of the healing products were determined using the EDX facility in the ESEM. It is shown that the precipitation of calcium carbonate is the main contributor to micro-crack healing at the crack mouth. The healing products initially appeared in an angular rhombohedral morphology which then underwent a discernable transformation in size, shape and surface texture, from relatively flat and smooth to irregular and rough, resembling the texture of the original surface areas surrounding the micro-cracks. It is also shown that exposure to the natural environment, involving intermittent wetting/drying cycles, promotes additional crystal growth, which indicates enhanced self-healing capability in this environment. - Highlights: •ESEM with EDX used to characterize the origin of micro-crack healing in an ECC •Evolution of healing precipitates studied at three specific locations over four weeks •Specimens exposed to laboratory environment, followed by the natural environment •Calcium carbonate is the main contributor to crack healing at the crack mouth. •Outdoor exposure involving intermittent rain promotes additional crystal growth.

    2014-02-01

    The evidence supporting chronic disease self-management warrants further attention. Our aim was to identify existing policies, strategies and frameworks that support self-management initiatives. This descriptive study was conducted as an environmental scan, consisting of an Internet search of government and other publicly available websites, and interviews with jurisdictional representatives identified through the Health Council of Canada and academic networking. We interviewed 16 representatives from all provinces and territories in Canada and found 30 publicly available and relevant provincial and national documents. Most provinces and territories have policies that incorporate aspects of chronic disease self-management. Alberta and British Columbia have the most detailed policies. Both feature primary care prominently and are not disease specific. Both also have provincial level implementation of chronic disease self-management programming. Canada's northern territories all lacked specific policies supporting chronic disease self-management despite a significant burden of disease. Engaging patients in self-management of their chronic diseases is important and effective. Although most provinces and territories have policies that incorporate aspects of chronic disease self-management, they were often embedded within other initiatives and/or policy documents framed around specific diseases or populations. This approach could limit the potential reach and effect of self-management.

    1998-01-01

    The development and construction of a remote sensing system used to detect and map oil and related petroleum products in complex marine and shoreline environments was reviewed. The Scanning Laser Environmental Airborne Fluorosensor (SLEAF) system will be integrated into Environment Canada's DC-3 aircraft and will be undergoing extensive testing to verify its functionality in an airborne environment. Laser fluorosensors are the only sensors that can successfully detect oil in most environments including snow and ice. One of the roles of SLEAF will be to confirm or reject suspected oil contamination sites that have been targeted by infrared or visible spectral cameras. The ability of the SLEAF system to detect, classify and estimate oil coverage has been tested using a total of twenty-one oils ranging from light refined crude through to heavy refined oils. The aromatic content of the oils varied between 13 and 52 per cent and the API gravities of the oils tested varied from 11.9 to 48.6. 10 refs., 2 tabs., 2 figs

    Full Text Available Systems navigation services provided by a designated provider or team have the potential to address health and social disparities. We conducted an environmental scan of navigation activities in a large urban Canadian community to identify and describe: service providers who engage in systems navigation; the clients who require systems navigation support and the issues they face; activities involved; and barriers and facilitators in providing systems navigation support to clients. Using an online survey and convenience sampling, we recruited individuals who self-identified as community navigators or practiced systems navigation activities as part of their role. The majority of respondents ( n  = 145 were social workers, social services workers, or nurses. Clients of navigators struggled with mental health or addictions issues, disabilities, chronic diseases, and history of trauma or abuse. The most frequently reported activities of navigators were building professional relationships, managing paperwork, and communicating with relevant agencies or organizations. Barriers to navigation were time available in the work day, difficulty partnering due to bureaucratic structures, differing philosophies and ways of working, and a lack of central information repository in the community. Facilitators were a client-centered organization, the availability of multiple community resources in the region, and organizational support. Participants struggled with client waitlists, system issues such as lack of resources and interagency collaboration, and role clarity.

    Purpose. To investigate the structure and irregularity of the capsulotomy cutting edges created by two femtosecond (FS) laser platforms in comparison with manual continuous circular capsulorhexis (CCC) using environmental scanning electron microscopy (eSEM). Methods. Ten anterior capsulotomies were obtained using two different FS laser cataract platforms (LenSx, n = 5, and Victus, n = 5). In addition, five manual CCC (n = 5) were obtained using a rhexis forceps. The specimens were imaged by eSEM (FEI Quanta 400, OR, USA). Objective metrics, which included the arithmetic mean deviation of the surface (Sa) and the root-mean-square deviation of the surface (Sq), were used to evaluate the irregularity of both the FS laser capsulotomies and the manual CCC cutting edges. Results. Several microirregularities were shown across the FS laser capsulotomy cutting edges. The edges of manually torn capsules were shown, by comparison of Sa and Sq values, to be smoother (P < 0.05) than the FS laser capsulotomy edges. Conclusions. Work is needed to understand whether the FS laser capsulotomy edge microirregularities, not seen in manual CCC, may act as focal points for the concentration of stress that would increase the risk of capsular tear during phacoemulsification as recently reported in the literature.

    Full Text Available Purpose. To investigate the structure and irregularity of the capsulotomy cutting edges created by two femtosecond (FS laser platforms in comparison with manual continuous circular capsulorhexis (CCC using environmental scanning electron microscopy (eSEM. Methods. Ten anterior capsulotomies were obtained using two different FS laser cataract platforms (LenSx, n=5, and Victus, n=5. In addition, five manual CCC (n=5 were obtained using a rhexis forceps. The specimens were imaged by eSEM (FEI Quanta 400, OR, USA. Objective metrics, which included the arithmetic mean deviation of the surface (Sa and the root-mean-square deviation of the surface (Sq, were used to evaluate the irregularity of both the FS laser capsulotomies and the manual CCC cutting edges. Results. Several microirregularities were shown across the FS laser capsulotomy cutting edges. The edges of manually torn capsules were shown, by comparison of Sa and Sq values, to be smoother (P<0.05 than the FS laser capsulotomy edges. Conclusions. Work is needed to understand whether the FS laser capsulotomy edge microirregularities, not seen in manual CCC, may act as focal points for the concentration of stress that would increase the risk of capsular tear during phacoemulsification as recently reported in the literature.

    Bioprosthetic heart valve tissue and associated calcification were studied in their natural state, using environmental scanning electron microscopy (ESEM). Energy dispersive X-ray micro-analysis, X-ray diffraction, Fourier-transform infrared and Raman spectroscopy were used to characterize the various calcific deposits observed with ESEM. The major elements present in calcified valves were also analyzed by inductively coupled plasma-optical emission spectroscopy. To better understand the precursor formation of the calcific deposits, results from the elemental analyses were statistically correlated. ESEM revealed the presence of four broad types of calcium phosphate crystal morphology. In addition, two main patterns of organization of calcific deposits were observed associated with the collagen fibres. Energy dispersive X-ray micro-analysis identified the crystals observed by ESEM as salts containing mainly calcium and phosphate with ratios from 1.340 (possibly octacalcium phosphate, which has a Ca/P ratio of 1.336) to 2.045 (possibly hydroxyapatite with incorporation of carbonate and metal ion contaminants, such as silicon and magnesium, in the crystal lattice). Raman and fourier-transform infrared spectroscopy also identified the presence of carbonate and the analyses showed spectral features very similar to a crystalline hydroxyapatite spectrum, also refuting the presence of precursor phases such as beta-tricalcium phosphate, octacalcium phosphate and dicalcium phosphate dihydrate. The results of this study raised the possibility of the presence of precursor phases associated with the early stages of calcification.

    Online training for systematic review methodology is an attractive option due to flexibility and limited availability of in-person instruction. Librarians often direct new reviewers to these online resources, so they should be knowledgeable about the variety of available resources. The objective for this project was to conduct an environmental scan of online systematic review training resources and evaluate those identified resources. The authors systematically searched for electronic learning resources pertaining to systematic review methods. After screening for inclusion, we collected data about characteristics of training resources and assigned scores in the domains of (1) content, (2) design, (3) interactivity, and (4) usability by applying a previously published evaluation rubric for online instruction modules. We described the characteristics and scores for each training resource and compared performance across the domains. Twenty training resources were evaluated. Average overall score of online instructional resources was 61%. Online courses (n=7) averaged 73%, web modules (n=5) 64%, and videos (n=8) 48%. The top 5 highest scoring resources were in course or web module format, featured high interactivity, and required a longer (>5hrs) time commitment from users. This study revealed that resources include appropriate content but are less likely to adhere to principles of online training design and interactivity. Awareness of these resources will allow librarians to make informed recommendations for training based on patrons' needs. Future online systematic review training resources should use established best practices for e-learning to provide high-quality resources, regardless of format or user time commitment.

    2006-04-15

    This paper maps the domain of earth and environmental sciences (EES) and investigates the relationship between cognitive problem structures and internationalisation patterns, drawing on the concepts of systemic versus cumulative global environmental change (GEC) and mutual task dependence in scientific fields. We find that scientific output concentration and internationalisation are significantly higher in the systemic GEC fields of Meteorology and Atmospheric Sciences and Oceanography than in the cumulative GEC fields Ecology and Water Resources. The relationship is explained by stronger mutual task dependence in systemic GEC fields. In contrast, the portion of co-authorships with developing, emerging and transition countries among all international publications is larger for Water Resources than for the three other fields, consistent with the most pressing needs for STI capacity development in these countries.

    An, X; Rainforth, W M; Chen, L

    2003-01-01

    The internal oxidation of Cr-Mn carburizing steel was studied. Internal oxidation was induced using a commercial carburizing process. Sputter erosion coupled with glow discharge optical emission spectroscopy (GDOES) was used to determine the depth profile elemental distribution within the internal oxidation layer (<10 mu m). In addition, scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS) studies were carried out on selected sputter eroded surfaces. Oxide type was identified primarily by transmission electron microscopy (TEM). The carburized surface was found to consist of a continuous oxide layer, followed by a complex internal oxidation layer, where Cr and Mn oxides were found to populate grain boundaries in a globular form in the near surface region. At greater depths (5-10 mu m), Si oxides formed as a grain boundary network. The internal oxides (mainly complex oxides) grew quickly during the initial stages of the carburizing process (2 h, 800 deg. C+3 h, 930 deg. C). G...

  19. Environmental risk comparisons with internal methods of UST leak detection

    Durgin, P.B.

    1993-01-01

    The past five years have seen a variety of advances in how leaks can be detected from within underground storage tanks. Any leak-detection approach employed within a storage tanks must be conducted at specific time intervals and meet certain leak-rate criteria according to federal and state regulations. Nevertheless, the potential environmental consequences of leak detection approaches differ widely. Internal, volumetric UST monitoring techniques have developed over time including: (1) inventory control with stick measurements, (2) precision tank testing, (3) automatic tank gauging (ATG), (4) statistical inventory reconciliation (SIR), and (5) statistical techniques with automatic tank gauging. An ATG focuses on the advantage of precise data but measured for only a brief period. On the other hand, stick data has less precision but when combined with SIR over extended periods it too can detect low leak rates. Graphs demonstrate the comparable amounts of fuel than can leak out of a tank before being detected by these techniques. The results indicate that annual tank testing has the greatest potential for large volumes of fuel leaking without detection while new statistical approaches with an ATG have the least potential. The environmental implications of the volumes of fuel leaked prior to detection are site specific. For example, if storage tank is surrounded by a high water table and in a sole-source aquifer even small leaks may cause problems. The user must also consider regulatory risks. The level of environmental and regulatory risk should influence selection of the UST leak detection method

  20. Assessing the Effectiveness of International Environmental Agreements (IEAs

    2014-02-01

    Full Text Available It is commonly claimed that assessing the effectiveness of International Environmental Agreements (IEAs from the environmental problem-solving perspective is challenging because environmental data are not available. However, not much research has been done on the characterization of the nature and causes of such data unavailability. This article analyzes the term “data unavailability” and provides three typologies for data unavailability: (a “true unavailability,” where data collection complexities and resource constraints limit data collection and analysis; (b “false unavailability,” which refers to the existence of relevant data, but failure to report due to various causes; and (c “external availability,” which refers to the existence of relevant data in several organizations and research institutions, but with no established networks for data sharing between such institutions and the IEA institutions. This article discusses the causes for the various types of data unavailability and makes recommendations for promoting data availability.

    Cooperative Agreement (DE-FC21-95EW55101) between the U.S. Department of Energy (DOE) and the Florida State University's Institute for International Cooperative Environmental Research (IICER) was designed to facilitate a number of joint programmatic goals of both the DOE and the IICER related to international technology identification, development, demonstration and deployment using a variety of mechanisms to accomplish these goals. These mechanisms included: laboratory and field research; technology demonstrations; international training and technical exchanges; data collection, synthesis and evaluation; the conduct of conferences, symposia and high-level meetings; and other appropriate and effective approaches. The DOE utilized the expertise and facilities of the IICER at Florida State University to accomplish its goals related to this cooperative agreement. The IICER has unique and demonstrated capabilities that have been utilized to conduct the tasks for this cooperative agreement. The IICER conducted activities related to technology identification, development, evaluation, demonstration and deployment through its joint centers which link the capabilities at Florida State University with collaborating academic and leading research institutions in the major countries of Central and Eastern Europe (e.g., Czech Republic, Hungary, Poland) and Russia. The activities and accomplishments for this five-year cooperative agreement are summarized in this Final Technical Report.

  2. Fast Focal Point Correction in Prism-Coupled Total Internal Reflection Scanning Imager Using an Electronically Tunable Lens

    2018-02-01

    Full Text Available Total internal reflection (TIR is useful for interrogating physical and chemical processes that occur at the interface between two transparent media. Yet prism-coupled TIR imaging microscopes suffer from limited sensing areas due to the fact that the interface (the object plane is not perpendicular to the optical axis of the microscope. In this paper, we show that an electrically tunable lens can be used to rapidly and reproducibly correct the focal length of an oblique-incidence scanning microscope (OI-RD in a prism-coupled TIR geometry. We demonstrate the performance of such a correction by acquiring an image of a protein microarray over a scan area of 4 cm2 with an effective resolution of less than 20 microns. The electronic focal length tuning eliminates the mechanical movement of the illumination lens in the scanning microscope and in turn the noise and background drift associated with the motion.

  3. Focusing on Environmental Biofilms With Variable-Pressure Scanning Electron Microscopy

    2006-12-01

    Since the term biofilm has been coined almost 30 years ago, visualization has formed an integral part of investigations on microbial attachment. Electron microscopic (EM) biofilm studies, however, have been limited by the hydrated extracellular matrix which loses structural integrity with conventional preparative techniques, and under required high-vacuum conditions, resulting in a loss of information on spatial relationships and distribution of biofilm microbes. Recent advances in EM technology enable the application of Variable Pressure Scanning Electron Microscopy (VP SEM) to biofilms, allowing low vacuum and hydrated chamber atmosphere during visualization. Environmental biofilm samples can be viewed in situ, unfixed and fully hydrated, with application of gold-sputter-coating only, to increase image resolution. As the impact of microbial biofilms can be both hazardous and beneficial to man and his environment, recognition of biofilms as a natural form of microbial existence is needed to fully assess the potential role of microbial communities on technology. The integration of multiple techniques to elucidate biofilm processes has become imperative for unraveling complex phenotypic adaptations of this microbial lifestyle. We applied VP SEM as integrative technique with traditional and novel analytical techniques to (1)localize lignocellulosic microbial consortia applied for producing alternative bio-energy sources in the mining wastewater industry, (2) characterize and visualize wetland microbial communities in the treatment of winery wastewater, and (3)determine the impact of recombinant technology on yeast biofilm behavior. Visualization of microbial attachment to a lignocellulose substrate, and degradation of exposed plant tissue, gave insight into fiber degradation and volatile fatty acid production for biological sulphate removal from mining wastewater. Also, the 3D-architecture of complex biofilms developing in constructed wetlands was correlated with

    1977-01-01

    Environmental and facility effluent radioactivity monitoring at Atomics International (AI) is performend by the Radiation and Nuclear Safety Unit of the Health, Safety, and Radiation Services Department. Soil, vegetation, and surface water are routinely sampled to a distance of 10 miles from AI sites. Continuous ambient air sampling and thermoluminescent dosimetry are performed on site for monitoring airborne radioactivity and site ambient radiation levels. Radioactivity in effluents discharged to the atmosphere from AI facilities is continuously sampled and monitored to ensure that levels released to unrestricted areas are within appropriate limits, and to identify processes which may require additional engineering safeguards to minimize radioactivity levels in such effluents. In addition, selected nonradioactive constituents in surface water discharged to unrestricted areas are determined. This report summarizes and discusses monitoring results for 1976. The results of a special soil plutonium survey performed during the year are also summarized

    2012-11-01

    In the run-up to the Rio+20 summit, which takes place in June 2012, this study investigates the current system for financing international environmental governance (IEG). The current architecture for IEG finance consists of a growing number of bilateral and multilateral actors, funds and financial mechanisms which leads to incoherence, inefficiencies and extra burdens on recipient countries. The resulting intransparency is exerbated by the lack of a comprehensive system for tracking. Against this background, this study investigates the current state of the IEG funding system from a qualitative and - to a lesser degree - quantitative angle. Some of its flaws are discussed as are options for its improvement - all with a view to formulating recommendations for the Rio+20 summit.

  8. International recommendations for managing environmental risk from nuclear energy production

    International Nuclear Information System (INIS)

    Clarke, R.H.

    1996-01-01

    The establishment of any recommendations relating to the control of radiation exposure requires decisions on the management of the associated risk. Those decisions must reflect attitudes towards the acceptable levels of risk for both workers and the public. The environmental impact of nuclear energy principally concerns radiation doses and risks to members of the public. The author shows how the considerations of risk and acceptability are used internationally to set standards for protection. The results differ as between limiting doses for normal operations, for restricting the likelihood of accidents, intervening after an accident, or reducing doses from a chronic exposure situation. It is concluded that there is a coherent pattern in the resulting protection system

    Based on the results of a pilot study at ORNL in 1973, a more comprehensive international intercomparison of integrating dosimeters for the assessment of external penetrating environmental radiation fields was carried out. Forty-one laboratories from eleven countries participated in this study. A total of 56 sets of six detectors each were mailed to and from Houston, Texas, where they were exposed for three months (July to September 1974) as follows: two in an unprotected space out-of-doors 1 m above ground; two in an air-conditioned shielded area with a known, low exposure rate; and two with the second group, but with an additional exposure to 30 mR. Evaluation of the dosimeters provides information on the calibration precision, the accuracy of field measurement, and transit exposure. Results are discussed. (U.S.)

    The Environmental Measurements Laboratory of the U.S. Department of Energy has conducted international intercomparisons of environmental dosemeters at regular intervals since 1974. This paper reports the results obtained in the 10th and 11th intercomparisons by JFB and JGY at the Australian Radiation Laboratory (in 1992 and 1996 respectively) and in the 12th intercomparison by JFB and DRCT at the Australian Radiation Protection and Nuclear Safety Agency and by JGY and JJ at Australian Radiation Serviceces during 2000 and 2001. The ARL/ARPANSA measurements used a simple dosemeter holder containing two CaSO 4 :Dy impregnated Teflon discs, one unshielded and the other shielded by approximately 2.4 mm of Cu. The ARS measurements used a commercially available TLD badge case containing a CaSO 4 :Dy impregnated Teflon card. The commercial badge case was not symmetrical in design. The filtration in the front and rear sections of the commercial badge case varied from an open area to an area shielded by copper, tin and cadmium. The results obtained were generally within ±15% of the reference values measured by EML using high-pressure ionisation chambers for dosemeters exposed hi the field to environmental radiation and for dosemeters given a single exposure to 137 Cs or 241 Am at EML or an associated laboratory. Similar agreement was obtained for dosemeters exposed in the field and also given a single exposure to 137 Cs radiation. In order to obtain this measure of agreement, the dosemeters were individually calibrated and the readouts corrected for fading. Copyright (2002) Australasian Radiation Protection Society Inc

  11. Coordination vs. voluntarism and enforcement in sustaining international environmental cooperation.

    Science.gov (United States)

    Barrett, Scott

    2016-12-20

    The fates of "transboundary" environmental systems depend on how nation states interact with one another. In the absence of a hegemon willing and able to coerce other states into avoiding a "tragedy of the commons," shared environments will be safeguarded if international cooperation succeeds and degraded or even destroyed if it fails. Treaties and related institutions of international law give form to these efforts to cooperate. Often, they implore states to act in their collective (as opposed to their national) interests. Sometimes, they impel cooperating states to punish free riders. A few agreements coordinate states' behavior. Here, I present simple game-theoretic models showing whether and how treaties and related institutions can change incentives, aligning states' self-interests with their collective interests. I show that, as a general matter, states struggle to cooperate voluntarily and enforce agreements to cooperate but that they find it relatively easy to coordinate actions. In some cases, the need for coordination is manifest. In other cases, it requires strategic thinking. Coordination may fall short of supporting an ideal outcome, but it nearly always works better than the alternatives.

    The oil industry is dynamic and global, being performed worldwide and by investors from several countries. In this sense, it is essential for investors to be informed of the legal frameworks in target countries and the differences between the legislation in those countries and their own legal systems. In this article, we will analyze the main differences on the environmental liability in Brazil, which is, currently, one of the most attractive markets in the oil and gas industry, the United States of America (US), the largest consumer of oil and the third producer around the world; and the European Union (EU) which concentrates the second largest global consumer, besides being the main player in the international and diplomatic relationships. Thus, the present paper, without the intent to exhaust the subject matter, aims at presenting comparisons between the legal environment of the three main players in the international oil and gas scenario, specifying not only the legal aspects of each of them, but also outlining the economic impacts generated over business investors from the oil industry, determining that although the differences in the basis of legal framework, all players have presented the liability and the duty to compensate.

    Full Text Available Negative attitudes and beliefs about individuals with obesity (also known as weight bias have negative consequences for physical and mental health for individuals with obesity and impact the quality of care provided by health professionals. A preliminary environmental scan of college and university training programs was conducted consisting of 67 degree and diploma granting programs from 22 institutions in Alberta, targeting programs training future health professionals. Publicly available online course descriptions were examined for weight-related keywords. Keyword frequency was used to determine the extent that coursework addressed weight-related issues. The results suggested that courses are structured to include learning about general health promotion as well as lifestyle factors that may contribute to obesity but may not systematically include learning about weight bias or its potential impact. Our findings highlight the need for further in-depth investigations as well as the need to enhance current curricula in higher education by including information related to weight, obesity and weight bias. Les attitudes et les croyances négatives concernant les personnes obèses (également connues comme partialité contre les obèses ont des conséquences négatives sur la santé physique et mentale des personnes obèses et affectent la qualité des soins qui leur sont prodigués par les professionnels de la santé.

    2005-05-01

    Delay between the time when natural disaster, for example, oil accident in coastal water, occurred and the time when environmental protection actions, for example, water and shoreline clean-up, started is of significant importance. Mostly remote sensing techniques are considered as (near) real-time and suitable for multiple tasks. These techniques in combination with rapid environmental assessment methodologies would form multi-tier environmental assessment model, which allows creating (near) real-time datasets and optimizing sampling scenarios. This paper presents the idea of three-tier environmental assessment model. Here all three tiers are briefly described to show the linkages between them, with a particular focus on the first tier. Furthermore, it is described how large-scale environmental assessment can be improved by using an airborne 3-D scanning FLS-AM series hyperspectral lidar. This new aircraft-based sensor is typically applied for oil mapping on sea/ground surface and extracting optical features of subjects. In general, a sampling network, which is based on three-tier environmental assessment model, can include ship(s) and aircraft(s). The airborne 3-D scanning FLS-AM series hyperspectral lidar helps to speed up the whole process of assessing of area of natural disaster significantly, because this is a real-time remote sensing mean. For instance, it can deliver such information as georeferenced oil spill position in WGS-84, the estimated size of the whole oil spill, and the estimated amount of oil in seawater or on ground. All information is produced in digital form and, thus, can be directly transferred into a customer"s GIS (Geographical Information System) system.

    Human exploration of the solar system is an ambitious goal. Future human missions to Mars or other planets will require the cooperation of many nations to be feasible. Exploration goals and concepts have been gathered by the International Space Exploration Coordination Group (ISECG) at a very high level, representing the overall goals and strategies of each participating space agency. The Global Exploration Roadmap published by ISECG states that international partnerships are part of what drives the mission scenarios. It states "Collaborations will be established at all levels (missions, capabilities, technologies), with various levels of interdependency among the partners." To make missions with interdependency successful, technologists and system experts need to share information early, before agencies have made concrete plans and binding agreements. This paper provides an overview of possible ways of integrating NASA, ESA, and JAXA work into a conceptual roadmap of life support and environmental monitoring capabilities for future exploration missions. Agencies may have immediate plans as well as long term goals or new ideas that are not part of official policy. But relationships between plans and capabilities may influence the strategies for the best ways to achieve partner goals. Without commitments and an organized program like the International Space Station, requirements for future missions are unclear. Experience from ISS has shown that standards and an early understanding of requirements are an important part of international partnerships. Attempting to integrate systems that were not designed together can create many problems. Several areas have been identified that could be important to discuss and understand early: units of measure, cabin CO2 levels, and the definition and description of fluids like high purity oxygen, potable water and residual biocide, and crew urine and urine pretreat. Each of the partners is exploring different kinds of technologies

    This Special Session is devoted to the secular evolution of disk galaxies. Here `secular' means `slow' i.e., evolution on time scales that are generally much longer than the galaxy crossing or rotation time. Internal and environmentally driven evolution both are covered. I am indebted to Albert Bosma for reminding me at the 2011 Canary Islands Winter School on Secular Evolution that our subject first appeared in print in a comment made by Ivan King (1977) in his introductory talk at the Yale University meeting on The Evolution of Galaxies and Stellar Populations: `John Kormendy would like us to consider the possibility that a galaxy can interact with itself.. . . I'm not at all convinced, but John can show you some interesting pictures.' Two of the earliest papers that followed were Kormendy (1979a, b); the first discusses the interaction of galaxy components with each other, and the second studies these phenomena in the context of a morphological survey of barred galaxies. The earliest modeling paper that we still use regularly is Combes & Sanders (1981), which introduces the now well known idea that box-shaped bulges in edge-on galaxies are side-on, vertically thickened bars. It is gratifying to see how this subject has grown since that time. Hundreds of papers have been written, and the topic features prominently at many meetings (e.g., Block et al. 2004; Falcoń-Barroso & Knapen 2012, and this Special Session). My talk here introduces both internal and environmental secular evolution; a brief abstract follows. My Canary Islands Winter School review covers both subjects in more detail (Kormendy 2012). Kormendy & Kennicutt (2004) is a comprehensive review of internal secular evolution, and Kormendy & Bender (2012) covers environmental evolution. Both of these subject make significant progress at this meeting. Secular evolution happens because self-gravitating systems evolve toward the most tightly bound configuration that is reachable by the evolution processes

    Human impact on the planet is causing a set of global environmental problems that threaten the wellbeing of current and future generations. Examples of these environmental problems include climate change, decline of biodiversity, alteration of biogeochemical cycles, ocean acidification, etc. These environmental Global Challenges (GCs) are transnational and complex, combining elements of both natural and social factors. Providing solutions for these challenges can be significantly enhanced through the collaboration of various related institutions, governments and stakeholders. A deeper understanding of the causes and consequences of GCs, as well as the processes which control them is required. Environmental Research Infrastructures (DANUBIUS-RI) are key players in this learning process. Covering many fields of research, it is through RIs collaboration that GCs can be more fully addressed. However, the collaboration among environmental RIs is still limited nationally as well as internationally. Although contact is encouraged and interactions are common practice, there are few cases where RI managers initiate and foster transnational collaborations in order to address specific problems. The COOP+ project aims to explore and strengthen cooperation among global RIs by bringing various RIs together and working on the identification of requirements, strengths, knowledge gaps and other relevant items in regard to the selected GCs. For this purpose, 13 GCs have been selected: coral bleaching, marine debris, noise impact on marine fauna, Arctic sea ice melting, pollinators decline, threatened species, agriculture pollutants, nitrogen cycle, carbon and GHG, geohazards and extreme events, estuaries, global urbanization process, and ozone depletion. These GCs are being analysed and described by multidisciplinary teams of experts composed of scientists, RIs operators and other stakeholders. This assessment will derive a list of tasks and requirements to be fulfilled by the

    A hollow circular cylinder specimen with an annular U-notch of chrome molybdenum steel with 0.20 mass% C (SCM420) was carburized in carrier gas and quenched in oil bath. In order to determine the case depth, the specimen was cut off and carbon content and Vickers hardness gradients were measured experimentally near the carburized surface. The residual strain mapping in the interior of carburized cylinder was conducted nondestructively by neutron strain scanning. In this study, the neutron diffraction from Fe-211 plane was used for strain scanning. The neutron wavelength was tuned to 0.1654nm so that diffraction angle became about 90deg. Radial, hoop and axial residual strains were measured by scanning diffracting volume along the axial direction of cylinder specimen. Each residual strain was calculated from lattice spacing change. Unstressed lattice spacing was determined experimentally using reference coupon specimens that were cut from the interior of same carburized cylinder. As a result, the diffraction peak width at half height, FWHM, near the carburized surface was about 3.7 times wider than that of coupon specimens. On the other hand, the most peak widths in the interior equaled to that of coupon specimens. Peak width broadened slightly as the diffracting volume approached the carburized case layer. From the center to the quarter of cylinder specimen, the hoop and axial strains were tensile, and the radial one was compressive in the interior. From the quarter to the edge of the cylinder specimen, the hoop tensile strain increased, radial and axial strains changed to tensile and compressive, respectively. Therefore, the interior of the cylinder specimen was found to be deformed elastically to balance the existence of compressive residual stresses in the carburized case layer. (author)

    The internal oxidation of Cr-Mn carburizing steel was studied. Internal oxidation was induced using a commercial carburizing process. Sputter erosion coupled with glow discharge optical emission spectroscopy (GDOES) was used to determine the depth profile elemental distribution within the internal oxidation layer (<10 μm). In addition, scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS) studies were carried out on selected sputter eroded surfaces. Oxide type was identified primarily by transmission electron microscopy (TEM). The carburized surface was found to consist of a continuous oxide layer, followed by a complex internal oxidation layer, where Cr and Mn oxides were found to populate grain boundaries in a globular form in the near surface region. At greater depths (5-10 μm), Si oxides formed as a grain boundary network. The internal oxides (mainly complex oxides) grew quickly during the initial stages of the carburizing process (2 h, 800 deg. C+3 h, 930 deg. C). GDOES proved to be an excellent tool for the quantification of oxidation and element distribution as a function of depth, particularly when combined with SEM and TEM to identify oxide type and morphology

    Full Text Available The participation and influence of non-governmental actors in areas of international environmental governance has increased tremendously over the last decades. Some of these non-governmental organization (NGOs, like International Union for Conservation of Nature, World Wide Fund for Nature or Greenpeace, have a global character and an intense activity in promoting environmental protection. Of great importance is the fact that some NGOs have gained a consultative status in international and regional organizations influencing the process of drafting and adopting norms of international environmental law. The study analyses the contribution of NGOs in international environmental field and their essential role as ,,guardians of the environment” in promoting and respecting the provisions of international environmental agreements, in particular of Aarhus Convention.

    Somatic embryogenesis (SE) is an important biotechnological technique used for the propagation of many pine species in vitro. However, in bog pine, one of the most endangered tree species in the Czech Republic, limitations were observed, which negatively influenced the development and further germination of somatic embryos. Although initiation frequency was very low-0.95 %, all obtained cell lines were subjected to maturation. The best responding cell line (BC1) was used and subjected to six different variants of the maturation media. The media on which the highest number of early-precotyledonary/cotyledonary somatic embryos was formed was supplemented with 121 μM abscisic acid (ABA) and with 6 % maltose. In the end of maturation experiments, different abnormalities in formation of somatic embryos were observed. For visualization and identification of abnormalities in meristem development during proliferation and maturation processes, the environmental scanning electron microscope was used. In comparison to the classical light microscope, the non-commercial environmental scanning electron microscope AQUASEM II has been found as a very useful tool for the quick recognition of apical meristem disruption and abnormal development. To our knowledge, this is the first report discussing somatic embryogenesis in bog pine. Based on this observation, the cultivation procedure could be enhanced and the method for SE of bog pine optimized.

  10. Prospects for international trade in environmental services: An analysis of international carbon emission off-sets

    International Nuclear Information System (INIS)

    Swisher, J.N.

    1991-01-01

    This dissertation presents a case study analysis in which the costs to a US electric utility of reducing its carbon dioxide (CO 2 ) emissions are compared with the costs of carbon-saving forestry projects in Costa Rica and Guatemala. The results show that a large electric utility in the south-central US would find it relatively inexpensive, even profitable given a conducive regulatory treatment, to reduce its CO 2 emissions by a few percent over the next ten years, through direct investment in energy end-use efficiency improvements. In comparison, the costs of the forestry projects studied in Central America range from $1/TC to a worst-case value of about $55/TC, with most project costs between $5 and $13/TC, depending on the type of project, the climate, and the opportunity cost of land. The total amount of CO 2 storage potential is significant, about 100 million tons per country, but not enough to suggest that forestry can offset more than a few percent of global CO 2 emissions from fossil fuel use. These case studies suggest that international trade in the environmental service of reducing global CO 2 accumulation could have significant economic and ecological benefits. A transaction in which a utility pays for forestry projects in exchange for credit against an emission reduction policy is an example of an international carbon emission offset (ICEO). ICEO's could provide a currency for funding carbon-saving services as a way to comply with national policies to reduce CO 2 emissions, as long as compliance is allowed through investments in other countries. This type of North-South transfer is necessary to reconcile economic efficiency and international equity, because of the disparity between the national allocations of responsibility for greenhouse gas emissions and opportunities for emission reductions

    As the next generation of scientists enters the field of environmental health, it is imperative that they view their contributions in the context of global environmental stewardship. In this commentary, a group of international graduate students facilitated by three experienced environmental health scientists present their views on what they consider to be the global environmental health concerns of today. This group convened initially in October 2004 at an international health conference in Prague, Czech Republic. In this report we identify perceived environmental health concerns that exist around the world, with a focus on Central and Eastern Europe. Additionally, we address these perceived problems and offers some potential solutions. At the meeting, students were invited to participate in two panel discussions. One group of young international scientists identified several significant global environmental health concerns, including air pollution, occupational hazards, and risk factors that may exacerbate current environmental health issues. The second panel determined that communication, education, and regulation were the mechanisms for addressing current environmental challenges. In this commentary we expand on the views presented at the meeting and represent the concerns of young investigators from nine different countries. We provide ideas about and support the exchange of information between developed and developing countries on how to handle the environmental health challenges that face the world today.

    Aim: An online survey has been used to assess the use of abdominal lead shielding on pregnant patients undergoing CT scans. The aim of the study was to identify potential geographical variations in the use of such shielding as well as the opinions of the users in terms of the weight, manoeuvrability and ergonomics of the lead shields. Materials and methods: The online questionnaire was distributed to CT Radiographers in the UK, Europe, North America and Australia and responses were gathered electronically over a six month period. All completed responses were downloaded and subsequently analysed for each geographical region. Results: In total, 390 completed questionnaires were received with over 100 from each of the UK, North America and Australia. The use of lead shielding was found to vary significantly across the globe with the highest usage in North America (94.5%) and the lowest usage in Europe (46.3%). Approximately 20% of all respondents said that they experienced occupationally related back pain and 25% of all respondents said that patients complained about the weight of the shielding. Conclusion: Significant geographical variations in both the use of lead shielding for foetal radiation protection and the users' opinions of the shielding devices that are used have been identified and it has become clear that existing shielding solutions are not optimised for this task.

  13. ISO 14000 - the International Environmental Management Standard: Potential impacts on environmental management and auditing in the electric power generation industry

    In the framework of environmental management, the concept of voluntary environmental compliance auditing is not in itself a new development. Environmentally conscious firms have for more than a decade, undertaken voluntary audits to help achieve and maintain compliance with environmental regulations and to help identify and correct unregulated or poorly regulated environmental hazard. The firms undertaking the audits were motivated by a desire to mitigate legal and financial risks and/or the desire to be a highly responsible member of the corporate community. Much of the early attention to environmental auditing was in the chemical process industries. Today, there are four current trends affecting environmental auditing: (1) the practice is becoming widespread in all industry groups in both large and small firms; (2) environmental management and audit methodolgies and approaches are being codified in the form of written national and International standards; (3) environmental management programs and in-house audits are increasingly being certified by independent auditors (who are not associated with regulatory agencies); and (4) the certifications are being viewed as marketing and public relations tools. The adoption of ISO 14000 is destined to become the most significant development in international environmental management and auditing. International standards for the development of Environmental Management Systems and the execution of environmental audits do not currently exist. Individual countries, such as England and France, have national standards. One multi-national standard currently exists--the European Economic Community's Eco-Management and Audit Scheme (EMAS). The United States does not have a national environmental management and auditing standard

    The standard view is that situations where no transborder environmental externalities occur are most efficiently dealt with by national environmental policies rather than by international co-operation. Though this may be the general case, non-coordinated national policies do not always produce the most efficient international allocation. This paper presents four cases in which the allocative outcome of non-coordinated domestic policy choices can be improved upon by international environmental co-operation. The first case refers to the use of environmental policy as a strategic trade instrument. The other cases refer to the existence of discrete technologies, set-up costs and increasing returns to scale. The form of international environmental co-operation should be adapted to the situation. Formal international agreements between countries are characterised by high transaction costs and may not always be the most efficient form of co-operation

  15. Optimal Differentiation of International Environmental Taxes in the Presence of National Labor Market Distortions

    2000-01-01

    We explore the implication of the 'double dividend' debate for international environmental taxes. In our scenario, small open economies with different labor market distortions follow a common environmental policy and use national environmental tax revenues to finance labor tax cuts. Since the double dividend hypothesis does not hold, a high labor tax implies a low environmental tax relative to other countries. The optimal differentiation of international environmental taxes is proven to be a function of the national labor tax rates and the uncompensated elasticities of labor supply. 20 refs

    We have designed, fabricated, and tested a compact gas-phase reactor for performing in situ soft x-ray scanning transmission x-ray microscopy (STXM) measurements. The reactor mounts directly to the existing sample holder used in the majority of STXM instruments around the world and installs with minimal instrument reconfiguration. The reactor accommodates many gas atmospheres, but was designed specifically to address the needs of measurements under water vapor. An on-board sensor measures the relative humidity and temperature inside the reactor, minimizing uncertainties associated with measuring these quantities outside the instrument. The reactor reduces x-ray absorption from the process gas by over 85% compared to analogous experiments with the entire STXM instrument filled with process gas. Reduced absorption by the process gas allows data collection at full instrumental resolution, minimizes radiation dose to the sample, and results in much more stable imaging conditions. The reactor is in use at the STXM instruments at beamlines 11.0.2 and 5.3.2.2 at the Advanced Light Source.

    The NASA Space Biology program funded two multi-year studies to catalogue International Space Station (ISS) environmental microbiome. The first Microbial Observatory (MO) experiment will generate a microbial census of the ISS surfaces and atmosphere using advanced molecular microbial community analysis "omics" techniques, supported by traditional culture-based methods and state-of-the art molecular techniques. The second MO experiment will measure presence of viral and select bacterial and fungal pathogens on ISS surfaces and correlate their presence on crew. The "omics" methodologies of the MO experiments will serve as the foundation for an extensive microbial census, offering significant insight into spaceflight-induced changes in the populations of beneficial and potentially harmful microbes. The safety of crewmembers and the maintenance of hardware are the primary goals for monitoring microorganisms in this closed habitat. The statistical analysis of the ISS microbiomes showed that three bacterial phyla dominated both in ISS and Earth cleanrooms, but varied in their abundances. While members of Actinobacteria were predominant on ISS, Proteobacteria dominated the Earth cleanrooms. Alpha diversity estimators indicated a significant drop in viable microbial diversity. To better characterize the shared community composition among samples, beta-diversity metrics analysis were conducted. At the bacterial species level characterization, the microbial community composition is strongly associated with sampling site. Results of the study indicate significant differences between ISS and Earth cleanroom microbiomes in terms of community structure and composition. Bacterial strains isolated from ISS surfaces were also tested for their resistance to nine antibiotics using conventional disc method and Vitek 2 system. Most of the Staphylococcus aureus strains were resistant to penicillin. Five strains were specifically resistant to erythromycin and the ermA gene was also

    The focal point of connecting trade and environment is what kind of influence over a national competitiveness of a national economy can be brought by enhancing environmental regulations. Traditionally it was accepted that the enhancement of environmental policy had a negative impact on competitiveness. However, recent study results show that the enhancement of environmental policy can strengthen industrial competitiveness for a long term. This study analyzes the significance of enhancing the international environmental regulation from a developing country's standpoint in association with this. 27 refs., 8 tabs.

  2. Near IR Scanning Angle Total Internal Reflection Raman Spectroscopy at Smooth Gold Films

    Energy Technology Data Exchange (ETDEWEB)

    McKee, Kristopher; Meyer, Matthew; Smith, Emily

    2012-04-13

    Total internal reflection (TIR) Raman and reflectivity spectra were collected for nonresonant analytes as a function of incident angle at sapphire or sapphire/smooth 50 nm gold interfaces using 785 nm excitation. For both interfaces, the Raman signal as a function of incident angle is well-modeled by the calculated interfacial mean square electric field (MSEF) relative to the incident field times the thickness of the layer being probed in the Raman measurement (D{sub RS}). The Raman scatter was reproducibly enhanced at the interface containing a gold film relative to the sapphire interface by a factor of 4.3–4.6 for aqueous pyridine or 2.2–3.7 for neat nitrobenzene, depending on the analyzed vibrational mode. The mechanism for the increased Raman signal is the enhanced MSEF at incident angles where propagating surface plasmons are excited in the metal film. The background from the TIR prism was reduced by 89–95% with the addition of the gold film, and the percent relative uncertainty in peak area was reduced from 15 to 1.7% for the 1347 cm–1 mode of nitrobenzene. Single monolayers of benzenethiol (S/N = 6.8) and 4-mercaptopyridine (S/N = 16.5) on gold films were measured by TIR Raman spectroscopy with 785 nm excitation (210 mW) without resonant enhancement in 1 min.

    The author analyses the current provisions in international law and international private law for their suitability to establish liability for damages due to transfrontier pollution, also taking into account damage occurred through the operation of nuclear power plants. As a result the author suggests that the national goverments should jointly set up standards and catalogues of environmentally detrimental effects and impacts, and of the seriousness thereof, and to make these form part of international conventions and agreements which also should unambigiously state liability for compensation for damages. For activities involving special hazards, liability for risks should be introduced in such a body of international regulations. (CB) [de

  4. International Environmental Agreements: Emissions Trade, Safety Valves and Escape Clauses

    Karp, Larry; Zhao, Jinhua

    2010-01-01

    We explain how the structure of multi-national or multi-regional environmental agreements affect their chance of success. Trade in emissions permits has ambiguous and in some cases surprising effects on both the equilibrium level of abatement, and on the ability to persuade nations or regions to participate in environmental agreements. An escape clause policy and a safety valve policy have essentially the same properties when membership in environmental agreement is pre-determined, but they create markedly different effects on the incentives to join such an agreement. The two policies lead to a qualitative difference in the leverage that a potential member of the agreement exercises on other members

    An environmental cell with a 50-nm-thick cathodoluminescent window was attached to a scanning electron microscope, and diffraction-unlimited near-field optical imaging of unstained living human lung epithelial cells in liquid was demonstrated. Electrons with energies as low as 0.8 - 1.2 kV are sufficiently blocked by the window without damaging the specimens, and form a sub-wavelength-sized illumination light source. A super-resolved optical image of the specimen adhered to the opposite window surface was acquired by a photomultiplier tube placed below. The cells after the observation were proved to stay alive. The image was formed by enhanced dipole radiation or energy transfer, and features as small as 62 nm were resolved.

It brought together a distinguished group of experts from Europe and abroad to address current issues of international and European environmental law. The main objective of the symposium was to take stock of the actors and principles of international and European environmental law, and to analyze how and to what extent these principles have been implemented on the supranational and domestic legal levels.

    Proteus mirabilis is a common cause of catheter-associated urinary tract infections and frequently leads to blockage of catheters due to crystalline biofilm formation. Scanning electron microscopy (SEM) has proven to be a valuable tool in the study of these unusual biofilms, but entails laborious sample preparation that can introduce artefacts, undermining the investigation of biofilm development. In contrast, environmental scanning electron microscopy (ESEM) permits imaging of unprocessed, fully hydrated samples, which may provide much insight into the development of P. mirabilis biofilms. Here, we evaluate the utility of ESEM for the study of P. mirabilis crystalline biofilms in situ, on urinary catheters. In doing so, we compare this to commonly used conventional SEM approaches for sample preparation and imaging. Overall, ESEM provided excellent resolution of biofilms formed on urinary catheters and revealed structures not observed in standard SEM imaging or previously described in other studies of these biofilms. In addition, we show that energy-dispersive X-ray spectroscopy (EDS) may be employed in conjunction with ESEM to provide information regarding the elemental composition of crystalline structures and demonstrate the potential for ESEM in combination with EDS to constitute a useful tool in exploring the mechanisms underpinning crystalline biofilm formation. © 2014 The Authors.

    Ongoing efforts by Health Canada intended to modernize the legislation and regulation of pharmaceuticals will help improve the safety and effectiveness of drug products. It will be imperative to ensure that comprehensive and specialized training sites are available to train researchers to support the regulation of therapeutic products. The objective of this educational institution inventory was to conduct an environmental scan of educational institutions in Canada able to train students in areas of post-market drug evaluation research. A systematic web-based environmental scan of Canadian institutions was conducted. The website of each university was examined for potential academic programs. Six core programmatic areas were determined a priori as necessary to train competent post-market drug evaluation researchers. These included biostatistics, epidemiology, pharmacoepidemiology, health economics or pharmacoeconomics, pharmacogenetics or pharmacogenomics and patient safety/pharmacovigilance. Twenty-three academic institutions were identified that had the potential to train students in post-market drug evaluation research. Overall, 23 institutions taught courses in epidemiology, 22 in biostatistics, 17 in health economics/pharmacoeconomics, 5 in pharmacoepidemiology, 5 in pharmacogenetics/pharmacogenomics, and 3 in patient safety/pharmacovigilance. Of the 23 institutions, only the University of Ottawa offered six core courses. Two institutions offered five, seven offered four and the remaining 14 offered three or fewer. It is clear that some institutions may offer programs not entirely reflected in the nomenclature used for this review. As Heath Canada moves towards a more progressive licensing framework, augmented training to increase research capacity and expertise in drug safety and effectiveness is timely and necessary.

  9. The role of international organizations with regard to environmental protection - the situation in Europe

    The international organisations more readily than most of the states accepted the idea that environmental protection cannot be achieved by compensation for damage or remedial actions in case of emergencies. They soon fostered an environmental policy intended to prevent pollution by creating a suitable, internationally accepted concept of requirements and procedures. Their activities in the last two decades largely contributed to an eventual reappraisal of approach by the states, which lead from a rather incoherent series of regional or national activities to an international, much more coherent concept of environmental policy. The international organisations also realised that efficient enforcement of pollution control measures will be guaranteed only by an adequate system of international laws, which still is to be agreed upon by the states. There still is a considerable lack of certainty of the law, with environmental problems increasingly pressing for a solution. (orig./HSCH) [de

    From the industrial revolution until the late 1960s, development and the environment were largely viewed as mutually exclusive. In the late 1960s a change in public awareness and attitude emerged, and since the U.N Conference on the Human Environment in 1972 there has been a significant change in the global perception of the relationship between the environment and development. Recognition that renewable resources, such as forests, atmospheric oxygen, and soil, can be harvested indefinitely through sound management practices has led to the current focus on sustainable development. When the National Environmental Policy Act was adopted in 1969, a comprehensive environmental management process was set in place. The impact of these regulations was felt by different industries at different levels, with the initial brunt being borne by the power industry, followed by the petroleum industry. In recent years the mining industry has been heavily impacted. Although industry has been increasingly regulated in the US since 1969, development in many other countries was not subject to environmental review or regulation. In recent years, however, this picture has changed dramatically. Currently, most other industrialized, and many developing countries have environmental laws, regulations, and review processes in place. For example, Indonesia, Thailand, Republic of China, Ecuador, Venezuela, Saudi Arabia, and Russia all have environmental laws, standards, and/or review requirements applicable to petroleum and other industrial developments. Most Western European and Pacific Rim countries have environmental standards and review processes in place. In Eastern Europe, Asia and South America, about half of the countries have regulations, and in Africa a small but growing number of countries have some level of environmental regulation

  15. An international comparison of the outcomes of environmental regulation

    Whilst there is much discussion about the stringency of environmental regulations and the variability of industrial environmental performance in different countries, there are very few robust evaluations that allow meaningful comparisons to be made. This is partly because data scarcity restricts the ability to make ‘like for like’ comparisons across countries and over time. This paper combines data on benzene emissions from Pollution Release and Transfer Registers with data on industrial production from oil refineries to generate normalized measures of industrial environmental performance across eight Organisation for Economic Cooperation and Development countries and the EU-15. We find that normalized emissions levels are improving in nearly all countries, and that there is some convergence in emissions performance between countries, but that there are still very significant variations across countries. We find that average emissions levels are lower in Japan and Germany than in the USA and Australia, which in turn are lower than in Canada and the EU-15, but we note that average emissions in the EU-15 are significantly affected by particularly high emissions in the UK. These findings have significant implications for wider debates on the stringency of environmental regulations and the variability of industrial environmental performance in different countries.

    The increased awareness of the transboundary pollution problems resulted in a number of international treaties, such as the Montreal protocol on ozone-depleting substances (1987), and the Basel Convention on hazardous waste (1989). Most authors writing on efficient environmental instruments make a sharp distinction between domestic and transboundary environmental problems. While the former should be abated by domestic environmental instruments, an efficient treatment of the latter requires international instruments. The underlying logic is that in case of non-transboundary pollution both the costs and benefits of environmental policies are strictly domestic, the trade-off between benefits and costs of abatement should also be a strictly domestic issue. In contrast, with transboundary pollution the trade-off between abatement costs and benefits becomes an international issue. In this paper we analyse four cases where international environmental co-ordination is required to achieve an efficient outcome, even though the environmental externality is non-transboundary in nature. Section two sketches the standard view on efficient intervention levels with regard to transborder and non-transborder pollution. In the third section we deal with cases where environmental policy is used in a trade-strategic way. The section pays attention to the motives for using domestic environmental policy as a disguise for trade policies. It will be argued that the resulting allocative efficiency can be improved upon by international co-operation. Sections 4-6 analyse three cases where international co-operation may improve the international outcome on the basis of non-coordinated domestic allocation decisions. These cases refer in particular to the situation of developing countries, when there is a high export dependency on the polluting good in combination with the existence of discrete technologies, set-up costs of environment-friendly technologies, and the existence of increasing

    We examine the optimal environmental regulation of three Norwegian power projects: energy conservation, a natural gas fired CCGT and a new hydro project. All projects reduce emissions elsewhere in the Nordic region, and the environmental costs of these emissions are not, in general, fully reflected in market prices. We develop a theory of second best optimal regulation for this case. The optimal regulation is found to deviate substantially from a purely domestic regulation. For instance, we find it optimal to grant a substantial credit to energy conservation. The credit is sensitive to the value of reduced CO 2 emissions and whether the current Norwegian end user tax should be interpreted as an environmental or a fiscal tax

    This report focuses on the possibility of establishing a High Commissioner for the Environment and transforming the UNEP Governing Council into a Council for the Environment. For this purpose, it considers the parallels between human rights regimes and environmental regimes. It provides a short-list of functions to be covered by a reformed environmental governance regime, and discusses how the reform can be coordinated with UNEP, as well as with the current and future institutional framework for sustainable development. The report also discusses how the reform can be related to fifteen core multilateral environmental agreements. Finally, the report considers how the reform can be carried out through a discussion of five separate options: a decision by the UN General Assembly, by the ECOSOC, or by the UNEP Governing Council, as well as through agreements between conferences of parties of environmental agreements, or directly between states. A main purpose of the report, which has been commissioned by the Norwegian Ministry for the Environment, is to provide input to the preparations for the Rio+20 Conference in 2012.(auth)

    Although there is evidence that environmental consequences for displaying tics and internalizing symptoms are related to tic severity in children with TS, less is known about the inter-relationships of these variables or how these factors jointly contribute to tic severity. This study included 45 children with Tourette syndrome. Caregivers reported on children's environmental consequences for displaying tics, internalizing symptoms, and tic severity. Results indicated that children with higher levels of internalizing symptoms experienced significantly more environmental consequences for displaying tics. Children with higher levels of separation anxiety symptoms demonstrated significantly greater tic severity. Environmental consequences for displaying tics accounted for significantly more variance in predicting tic severity than anxiety symptoms. This preliminary evidence suggests that environmental consequences for displaying tics, such as receiving accommodations or attention from others, have a greater influence on children's tic severity than emotional factors.

    The Space Communications and Navigation (SCaN) is a facility developed by NASA and hosted on board the International Space Station (ISS) on an external truss since 2013.It has the objective of testing navigation and communication experimentations with a Software Defined Radio (SDR) approach, which permits software updates for testing new experimentations.NASA has developed the Space Telecommunications Radio System (STRS) architecture standard for SDRs used in space and ground-based platforms to provide commonality among radio developments to provide enhanced capability. The hardware is equipped with both L band front-end radios and the NASA space network communicates with it using S-band, Ku-band and Ka-band links.In May 2016 Qascom started GARISS (GPS and Galileo Receiver for the ISS), an activity of experimentation in collaboration with ESA and NASA that has the objective to develop and validate the acquisition and processing of combined GPS and Galileo signals on board the ISS SCaN testbed. This paper has the objective to present the mission, and provide preliminary details about the challenges in the design, development and verification of the waveform that will be installed on equipment with limited resources. GARISS is also the first attempt to develop a waveform for the ISS as part of an international collaboration between US and Europe. Although the final mission objective is to target dual frequency processing, initial operations will foresee a single frequency processing. Initial results and trade-off between the two options, as well as the final decision will be presented and discussed. The limited resources on board the SCaN with respect to the challenging requirements to acquire and track contemporaneously two satellite navigation systems, with different modulations and data structure, led to the need to assess the possibility of aiding from ground through the S-band. This option would allow assistance to the space receiver in order to provide

    In the standard emission problem, each country’s ruling party decides on an optimal level of emissions by analyzing the cost and benefit to the country. However, such policy decisions are often influenced by political parties’ incentives to be elected. Voters tend to give higher priority to economic issues than they do to environmental ones. As a result, political parties have additional incentives to reach a critical economic benefit level, at a cost of higher emission level, in order to sat...

    Environmental protection of natural ecosystems against the effects of radiation has been largely predicated upon human radiological protection regimes. It has been explicitly assumed that if human populations are adequately protected then this will also confer protection to other species at the population level and hence to the 'environment'. Accordingly, non-human organisms have principally been incorporated into regulatory and assessment frameworks in recognition of their role as part of diverse critical pathways of radionuclide transfer to human populations. Hence, the utility of these non-human organisms in assessing hazards to ecosystems is strictly limited since their selection for monitoring purposes relates more to human perspectives than to their role and importance in natural ecosystems. By contrast, a multispecies ecosystem level approach should work on the basis of selecting 'keystone' species and evaluating the effects of radiation upon natural ecosystem dynamics. This would accommodate the full range of sub-lethal effects, differential life-stage sensitivity, reproductive sensitivity and interspecific interactions. While such an approach would undoubtedly improve the current situation, experience from chemical ecotoxicology suggests that the selection and verification of suitable endpoints will prove difficult beyond an organismal level. Thus, a regulatory regime based upon this approach is almost certain to be less than effective at protecting the environment. The precautionary approach to environmental protection has largely grown from an awareness of the limitations of ecotoxicological studies and protocols. This paper, therefore, considers the need for application of such an approach in relation to environmental protection requirements of the nuclear industry

    The COMPASS experiment at CERN uses a secondary pion beam from the Super Proton Synchrotron (SPS) at CERN to explore the spin structure of nucleons. A new drift chamber, DC5, will be integrated into the COMPASS spectrometer to replace an aging straw tube detector. DC5 will detect muon pairs from Drell-Yan scattering of a pion-beam off a transversely polarized proton target. This data will be used to determine the correlation between transverse proton spin and the intrinsic transverse momentum of up-quarks inside the proton, the Sivers effect. DC5 is a large area planar drift chamber with 8 layers of anode-frames made of G10 fiberglass-epoxy. The G10 frames support printed circuit boards for soldering 20 μm diameter anode and 100 μm diameter field wires. The anode planes are sandwiched by 13 graphite coated Mylar cathode planes. To ensure a well-functioning of DC5, the wires were carefully tested. An optical inspection and a spectral analysis was performed with an Environmental Scanning Electron Microscope (ESEM) to verify the composition and dimensions and the integrity of the gold plating on the surface of these wires. The spectra of the wires were studied at 10 and 30 keV.

    The present investigation provides novel information on the topographical distribution of macrophages and dendritic cells (DCs) in normal meninges and choroid plexus of the rat central nervous system (CNS). Whole-mounts of meninges and choroid plexus of Lewis rats were incubated with various anti-leucocyte monoclonal antibodies and either visualised with gold-conjugated secondary antibody followed by silver enhancement and subsequent examination by environmental scanning electron microscopy or by the use of fluorochromes and confocal microscopy. Large numbers of MHC class II(+) putative DCs were identified on the internal or subarachnoid aspect of dural whole-mounts, on the surface of the cortex (pia/arachnoid) and on the surface of the choroid plexus. Occupation of these sites would allow DCs access to cerebrospinal fluid (CSF) and therefore allow antigens into the subarachnoid space and ventricles. By contrast, macrophages were less evident at sites exposed to CSF and were more frequently located within the connective tissue of the dura/arachnoid and choroid plexus stroma and also in a sub-pial location. The present data suggest that DC may be strategically located within the CNS to sample CSF-borne antigens. Furthermore, the data suggest that CNS tissue samples collected without careful removal of the meninges may inadvertently be contaminated by DCs and meningeal macrophages.

    Environmental models using radioecological parameters are essential for predicting the behavior of radionuclides in the environment. Due to the complex behaviors of radionuclides in the environment, simplified models and parameters with ample margins are used for the safety assessment of nuclear facilities to ensure the safety of people in the surrounding area. As a consequence, radiation exposure doses from the radionuclides have generally been overestimated. Information with more precise predictions of the fate of the radionuclides in the environment and realistic radiation dose estimates are necessary for the public acceptance of nuclear facilities. Realistic dose estimates require continuous improvement of the models and their parameters as well as using state of the art modeling techniques and radioecological knowledge. The first commercial nuclear fuel reprocessing plant in Japan has been built in Rokkasho, Aomori, and the Institute for Environmental Sciences was established for the purpose of assessing the effects of radionuclides released from the plant. Test runs by the plant using actual spent nuclear fuel began in March 2006. With commercial operation soon to begin, there is increasing concern regarding the behavior of radionuclides in the environment. This was a good time to hold a symposium here in Rokkasho to discuss recent progress in the field of environmental modeling and studies of the behaviors of radionuclides in the environment. The exchange of up-to-date information between modelers and experiments was an important aspect of the symposium. The symposium featured 26 oral lectures and 32 poster presentations. The 57 of the presented papers are indexed individually. (J.P.N.)

    According to this report, voluntary agreements have a potential as instruments for environmental policy. Such agreements can be national or international. Through an international voluntary agreement the authorities in one country may make contracts with factories in another country about emission reductions against some kind of compensation. A supranational organisation of voluntary agreements may ensure equal environmental political conditions for factories in different countries and be a useful means for the regulation of environmental problems of regional or global extent. It is most realistic to establish a supranational system of voluntary agreements in a group of countries that have already institutionalized their relations, such as the European Union. 14 refs., 1 table

    According to the agreed burden sharing within the European Union the overall EU emission reduction target as agreed by in the Kyoto protocol is converted into national greenhouse gas reduction-targets for each of the member states. In parallel with national emission reduction initiatives common EU policies for emission reductions are considered. Currently discussed is the introduction of a market for tradable permits for CO 2 -emissions to achieve emission reductions within the power industry and other energy intensive industries. In parallel with this markets for green certificates to deploy renewable energy technologies seem to be appearing in a number of countries, among these Denmark, Italy, Sweden, Belgium (Flanders), England and Australia. Although these national initiatives for a green certificate market are fairly different, they could be a starting point for establishing a common EU certificate market. But interactions between national targets for greenhouse gas emissions and these international instruments for emission reduction are not a trivial matter, especially not seen in relation to the possible contributions of these instruments in achieving national GHG-reduction targets. The paper is split into three parts all taking a liberalised power market as starting point: The first part discusses the consequences of a general deployment of renewable energy technologies, using planning initiatives or national promotion schemes (feed-in tariffs). In the second part an international green certificate market is introduced into the liberalised power market context, substituting other national promotion schemes. Finally, in the third part a combination of an international green certificate market (TGC) and an international emission-trading scheme for CO 2 is analysed within the liberalised international power market set-up. The main conclusion is that neither the use of national renewable support schemes nor the introduction of a TGC-market into a liberalised

    There exists a connection between the economic structural orientation and international competitiveness on the one hand as well as the environmental political requirements on the other hand. The environmental protection economy fits quite well the profile that Germany is demanded in the international change. Under this aspect, the authors of the contribution under consideration report on the production structure and on the international competition position of the German environmental protection economy. The authors report on (a) the production structure and production dynamics of the environmental protection industry; (b) German environmental protection economy in the international comparison; (c) Goods, building works and services for environmental protection in Germany.

    The resolution of a 33+-3 μm microprobe focussed with quadrupole doublet installed at the 3 MV Van de Graaff of the National Institute of Radiological Sciences, Japan, was used for the present analysis. Brown algae, Hizikia fusiforme was the sample target bombarded with a 2 MeV proton beam collimated mechanically into a rectangular image of 100 μm x 700 μm. Scanning across the sample target prepared into a longitudinal section from the caulis of the algae provided the following observations. More than 12 elements such as Al, Si, P, Cl, Ca, Mn, Fe, Cu, Zn, As, Br and Sr were determined simultaneously, together with their distributional information across the diameter. In the medullary layer, Mn and Zn were specific in their accumulation, while the deposition of Fe, Cu, As and Br were observed to be high in the epithelial layer, especially Fe and Cu which were found on the surface, where they contacted ambient sea water, but no significant change in pattern was indicated for such elements as Al, P and Cl. The PIXE microprobe analysis was, therefore, effective in its detectability for elements below a few ppm level, resultantly providing further possibilities for collecting information from bio-medical and environmental samples on trace characterization of elements.

    Approximately 24,000 Ontarians live in remote Indigenous communities with no road access. These communities are a subset of Nishnawbe Aski Nation (NAN), a political grouping of 49 First Nations communities in Northern Ontario, Canada. Limited information is available regarding the status of emergency care in these communities. We aimed to understand emergency response systems, services, and training in remote NAN communities. We used an environmental scan approach to compile information from multiple sources including community-based participatory research. This included the analysis of data collected from key informant interviews (n=10) with First Nations community health leaders and a multi-stakeholder roundtable meeting (n=33) in October 2013. Qualitative analysis of the interview data revealed four issues related to emergency response systems and training: (1) inequity in response capacity and services, (2) lack of formalised dispatch systems, (3) turnover and burnout in volunteer emergency services, and (4) challenges related to first aid training. Roundtable stakeholders supported the development of a community-based emergency care system to address gaps. Existing first response, paramedical, and ambulance service models do not meet the unique geographical, epidemiological and cultural needs in most NAN communities. Sustainable, context-appropriate, and culturally relevant emergency care systems are needed.

    Full Text Available Dyed natural rubber (NR and styrene butadiene rubber (SBR, designed for outdoor applications, were exposed to an accelerated artificial aging in xenon light. The aging results in the deterioration of the exposed surface material properties. The ability of dyed polymers to withstand prolonged sunlight exposure without fading or undergoing any physical deterioration is largely determined not only by the photochemical characteristics of the absorbing dyestuff itself but also by the polymer structure and fillers. Results obtained by laser mass spectrometry, UV-visible spectroscopy, and environmental scanning electron microscopy indicate that dyed filled NR and SBR samples behave differently during the photo-oxidation. The fading of the dyed polymers was found to be promoted in the NR sample. This can be correlated with LDI-FTICRMS results, which show the absence of [M-H]− orange pigment pseudomolecular ion and also its fragment ions after aging. This is confirmed by both EDX and UV/Vis spectroscopy. EDX analysis indicates a concentration of chlorine atoms, which can be considered as a marker of orange pigment or its degradation products, only at the surface of SBR flooring after aging. Reactivity of radicals formed during flooring aging has been studied and seems to greatly affect the behavior of such organic pigments.

    The potential relationship between domestic environmental regulation and international competitiveness has evoked various speculations. The common neoclassical train of thought is that strict environmental regulation is detrimental to the competitiveness of industry, and that it induces phenomena such as ecological dumping, ecological capital flight, and regulatory 'chill' in environmental standards. A different view is that strict environmental regulation triggers industry's innovation potential, and subsequently increases its competitiveness. The impact of environmental regulation on competitiveness has been analyzed in terms of international capital movements, new firm formation, and international trade. This paper focuses on a statistically rigorous analysis of international trade studies, using a technique that is known as meta-analysis. The paper presents a statistically supported evaluation of the literature, in order to assess what the main conclusions regarding the relationship between environmental regulation and competitiveness are when it comes to studies on international trade flows. The synthesis of the literature is subsequently used to present guidelines for future primary research in this area.

    Full Text Available The main purpose of this paper is to use the fuzzy analytic hierarchy process (FAHP approach to evaluate the key environmental risk factors for pollution at international ports in Taiwan. Relying on the literature and experts’ opinions, a hierarchical structure with three risk aspects and thirteen risk factors is first constructed, and a FAHP model then proposed. Based on data from the AHP experts’ questionnaires, we use the FAHP approach to determine key environmental risk factors. Finally, the results show that: (1 Air pollution is the most important aspect of environmental pollution at international ports in Taiwan. (2 In order of relative importance, the top five key environmental risk factors for pollution at international ports in Taiwan are the oil leaks from ships, volatile organic compounds (VOCs, exhaust emissions from ships at berth, harmful coatings on ships' hulls, and ships' failure to use low-pollution fuel. Furthermore, some discussions are provided for port authority in Taiwan.

  7. International cooperation as a mechanism for the development of environmental management Theoretical approach to the Global Environmental Management Structure

    Miranda Morales, Paola Maria

    2011-01-01

    This work presents a theoretical study of a global environmental management structure. This structure can be made possible after a new Global Environmental Order (CID) is established. The new order should be supported by the international development politics. It also has to be funded in the understanding of the interaction dynamics: ecosystem- culture. The theoretical studies of this work on global environmental Management allowed identifying the main difficulties to be overcome by the CID in order to fulfill its role as a leading actor in the global environmental transformation. The first issue to be considered by the CID is related to the fact that the actual regulation and follow up politics are insufficient. A second difficulty has to do with the very few results obtained on guaranteeing fair exchange of information and technology between Northern and Southern countries.

    Numerous studies on HNC services have been carried out by signifying their needs, efficiency and effectiveness. However, no study has ever been performed to determine the critical factors associated with HNC's positive results despite the deluge of positive studies on the service. This study included all of the 89 training hospitals that were practising HNC service in Korea as of November 2006. The input factors affecting the performance were classified as either internal or external environmental factors. This analysis was conducted to understand the impact that the corresponding factors had on performance. Data were analysed by using multiple linear regressions. The internal and external environment variables affected the performance of HNC based on univariate analysis. The meaningful variables were internal environmental factors. Specifically, managerial resource (the number of operating beds and the outpatient/inpatient ratio) were meaningful when the multiple linear regression analysis was performed. Indeed, the importance of organizational culture (the passion of HNC nurses) was significant. This study, considering the limited market size of Korea, illustrates that the critical factor for the development of hospital-led HNC lies with internal environmental factors rather than external ones. Among the internal environmental factors, the hospitals' managerial resource-related factors (specifically, the passion of nurses) were the most important contributing element. © 2011 The Authors.

    Where financing is concerned, two major players for US based international power projects are The World Bank and the Export-Import Bank of the US (Ex-Im Bank). The concern for environmental protection is a global issue, yet many countries still have no enforceable environmental regulations for power generation facilities. In the past, many projects were developed with little or no environmental controls. However, designing a power generation project to meet The World Bank environmental guidelines is now generally regarded as standard practice for independent power projects in the developing world (Price et al, 1994). The World Bank standards are mandatory for projects financed by The World Bank, through the International Finance Corporation (IFC), or associated programs like the Expanded Cofinancing Program of the International Bank for Reconstruction and Development (IBRD). The Ex-Im Bank has recently established new environmental procedures and guidelines that went into effect on February 1, 1995. In order to avoid a competitive disadvantage for US exporters and still provide a means for global environmental protection, Ex-Im Bank has taken a leadership role in encouraging the adoption of common environmental procedures and standards by leading export credit agencies around the world. Until such procedures are established, Ex-Im Bank is seeking to establish common lines in specific cases with the Organization for Economic Cooperation and Development (OECD) on environmental standards for appropriate projects (Ex-Im, 1994)

    The Space Communications and Navigation (SCaN) Program Office at NASA Headquarters oversees all of NASAs space communications activities. SCaN manages and directs the ground-based facilities and services provided by the Deep Space Network (DSN), Near Earth Network (NEN), and the Space Network (SN). Through the SCaN Program Office, NASA GRC developed a Software Defined Radio (SDR) testbed experiment (SCaN testbed experiment) for use on the International Space Station (ISS). It is comprised of three different SDR radios, the Jet Propulsion Laboratory (JPL) radio, Harris Corporation radio, and the General Dynamics Corporation radio. The SCaN testbed experiment provides an on-orbit, adaptable, SDR Space Telecommunications Radio System (STRS) - based facility to conduct a suite of experiments to advance the Software Defined Radio, Space Telecommunications Radio Systems (STRS) standards, reduce risk (Technology Readiness Level (TRL) advancement) for candidate Constellation future space flight hardware software, and demonstrate space communication links critical to future NASA exploration missions. The SCaN testbed project provides NASA, industry, other Government agencies, and academic partners the opportunity to develop and field communications, navigation, and networking technologies in the laboratory and space environment based on reconfigurable, software defined radio platforms and the STRS Architecture.The SCaN testbed is resident on the P3 Express Logistics Carrier (ELC) on the exterior truss of the International Space Station (ISS). The SCaN testbed payload launched on the Japanese Aerospace Exploration Agency (JAXA) H-II Transfer Vehicle (HTV) and was installed on the ISS P3 ELC located on the inboard RAM P3 site. The daily operations and testing are managed out of NASA GRC in the Telescience Support Center (TSC).

    The importance of measuring the quality of end-of-life care provision is undisputed, but determining how best to achieve this is yet to be confirmed. This study sought to identify and describe national end-of-life care quality indicators and supporting policies used by countries leading in their end-of-life care provision. A systematic environmental scan that included a web search to identify relevant national policies and indicators; hand searching for additional materials; information from experts listed for the top 10 (n=15) countries ranked in the 'quality of care' category of the 2015 Quality of Death Index study; and snowballing from Index experts. Ten countries (66%) have national policy support for end-of-life care measurement, five have national indicator sets, with two indicator sets suitable for all service providers. No countries mandate indicator use, and there is limited evidence of consumer engagement in development of indicators. Two thirds of the 128 identified indicators are outcomes measures (62%), and 38% are process measures. Most indicators pertain to symptom management (38%), social care (32%) or care delivery (27%). Measurement of end-of-life care quality varies globally and rarely covers all care domains or service providers. There is a need to reduce duplication of indicator development, involve consumers, consider all care providers and ensure measurable and relevant indicators to improve end-of-life care experiences for patients and families. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  16. Experimental study of water sorption and clays swelling by environmental scanning electron microscopy (ESEM) and digital image analysis

    Montes-Hernandez, G.

    2002-10-01

    This work deals with the study of water sorption and clays swelling (MX80 bentonite and Paris basin argilites). A new approach by environmental scanning electron microscopy (ESEM) coupled to digital image analysis is proposed to estimate the swelling with time and the relative humidity. The ESEM is a new generation tool, not much used in the clays domain, which allows to study hydrated materials in different conditions of relative humidity. In this work, it is shown that qualitative and quantitative information about clays swelling at the aggregate scale can be obtained. The study of the kinetics allows to identify three swelling steps which are described by a first order kinetic model. The study of water sorption by raw bentonite and the exchange of different cation (Na + , Li + , K + , Ca 2+ , Mg 2+ ) has permitted to analyze the cation influence on the swelling potential. The adsorption kinetics, described by a second order model, depends directly on the relative humidity, on the mass of the sample and on the compensating cation. The study of the texture of the compacted MX80 bentonite in dry and humid conditions has permitted to observe the morphological evolution of the porous network (macro-porosity) during the hydration/dehydration. From different analytical approaches, a diminution of the macro-pores and/or meso-pores size and the opening of inter-aggregate pores is observed when the apparent density increases. The study of the influence of the instantaneous water condensation/evaporation on the argilites shows that the sensitiveness to water increases when the proportion of clay increases. In particular, it is characterized by a cracking partially reversible or irreversible after several condensation/evaporation cycles. (J.S.)

    Background Newer behavior genetic methods can better elucidate gene-environment (G-E) interplay in the development of internalizing (INT) disorders (i.e., major depression and anxiety disorders). However, no study to date has conducted a comprehensive analysis examining multiple environmental risks with the purpose of delineating how general G-E mechanisms influence the development of INT disorders. Methods The sample consisted of 1315 male and female twin pairs participating in the age 17 assessment of the Minnesota Twin Family Study. Quantitative G-E interplay models were used to examine how genetic and environmental risk for INT disorders changes as a function of environmental context. Multiple measures and informants were employed to construct composite measures of INT disorders and 6 environmental risk factors including: stressful life events, mother-child and father-child relationship problems, antisocial and prosocial peer affiliation, and academic achievement and engagement. Results Significant moderation effects were detected between each environmental risk factor and INT such that in the context of greater environmental adversity, nonshared environmental factors became more important in the etiology of INT symptoms. Conclusion Our results are consistent with the interpretation that environmental stressors have a causative effect on the emergence of INT disorders. The consistency of our results suggests a general mechanism of environmental influence on INT disorders regardless of the specific form of environmental risk. PMID:19594836

    The aim of this research is to expand the knowledge on the integration of environmental issues in the organisation and management of multinational corporations (MNCs). The present study analyses the characteristics and determining factors of the environmental strategy and the organisation of environmental management (structure) in the petroleum industry, driven by the following general question: (1) Which factors influence the relationship between environmental strategy and environmental structure in a multinational corporation? Sub-questions have been formulated to enable this analysis for the international petroleum industry: Q1: How can external contextual characteristics be classified in such a way that a relationship with environmental strategy and environmental structure can be studied?; Q2: How can internal characteristics of MNCs be characterised, in such a way that a relationship with environmental strategy and environmental structure can be studied?; and Q3: How can environmental strategy and structure of large MNCs be characterised, in such a way that influencing factors can be identified? To these ends, the research project has adjusted the strategic alignment model for environmental issues in MNCs. It is introduced as the 'International Environmental Alignment Framework'. As further discussed in Chapter 3, strategic alignment examines the cooperative and/or conflicting relationship between strategy and structure with the aim of improving efficiency and performance. Building on the concepts of strategic fit and functional integration, this model assumes that decisions need to be coordinated to achieve value. The International Environmental Alignment Framework copied the distinction between an internal, functional domain and an external, strategic domain. This allows for the inclusion of company, sector and country variables. Furthermore, the framework distinguishes three different orders of alignment (simple consistency, mutual reinforcement

    Tritiated water (HTO) released from the nuclear facilities can easily be absorbed by plants via their stomata and incorporated into organics by metabolic processes such as photosynthesis. Organically bound tritium (OBT) in plant cells is mostly inexchangeable and remains at harvest to contribute some to the ingestion radiation dose (Barry et al., 1999). In assessing the ingestion dose due to an accidental release of HTO, a dynamic model simulating its environmental behaviors is needed. Various types of dynamic HTO models have been developed in many different countries. Joint international researches have been conducted many times for model comparisons and validations (BIOMOVS II, 1996a, 1996b). In 2003, however, with the understanding of an insufficiency in the validation test, the IAEA started on a joint international research program for the validation of environmental models (EMRAS : Environmental Modelling for Radiation Safety) as a successor to the BIOMASS (2001). The KAERI submitted 'a scenario of an acute soybean exposure to HTO' to the Tritium Working Group (Theme 1) in the EMRAS program. It was accepted as Task 2 of the working group. This report is the result of a joint research for the KAERI scenario carried out by the EMRAS tritium working group with the KAERI playing a role of a coordinator.

  13. International jurisprudence on trade and environmental health: one step forward, two steps back?

    Science.gov (United States)

    Timmermans, Karin

    2008-01-01

    Since the creation of the World Trade Organization (WTO), there has been considerable debate regarding the impact of its rules on public health. By contrast, the role of the WTO dispute settlement mechanism has received little attention, even though the bodies responsible for settling disputes are the ultimate interpreters of WTO rules and agreements. To date, three WTO disputes that relate to occupational and/or environmental health have been fully litigated. A review of the decisions and reasoning in these cases indicates that WTO jurisprudence is evolving, as Panels and the Appellate Body try--with varying degrees of success--to balance countries' rights and obligations under international trade agreements with their right to protect occupational and environmental health. Disputes between nations can have an impact beyond the parties concerned, and raise questions about the relationship between trade agreements and other international agreements, especially multilateral environmental agreements (MEAs).

  15. MISSION AND VISION, ENVIRONMENTAL SCANNING AND FORMALITY OF STRATEGIC PLANNING AS PREDICTORS OF THE PERFORMANCE OF SMALL AND MEDIUM ENTERPRISES (SMES IN THE GAUTENG PROVINCE OF SOUTH AFRICA

    Directory of Open Access Journals (Sweden)

    Maxwell SANDADA

    2014-07-01

    Full Text Available Faced with volatile business conditions and the hyper competitive market environment, SMEs are continuously focusing on finding ways to improve their performance. This paper attempts to establish the effect of mission and vision, environmental scanning and the formality of the strategic planning process on the performance of SMEs. A quantitative research approach was pursued through a self-administered survey questionnaire. Descriptive statistics, correlation analysis and regression analysis were used to analyse the data. The main findings of the study suggest that, the mission and vision statements, environmental scanning and the formality of strategic planning have a positive effect on the performance of SMEs. The formality of strategic planning emerged as the factor with a stronger impact on SME performance than environmental scanning and mission and vision. The study provides some practical insights for SMEs for improving their performance in line with the identified effect of these three factors. Ultimately, improving their performance along these factors is set to reinforce SME sustainability and which will further stimulate their profitability.

    Recent work on procrastination has begun to unravel the genetic and environmental correlates of this problematic behavior. However, little is known about how strongly procrastination is associated with internalizing and externalizing psychopathology, and the extent to which shared genetic/environmental factors or relevant personality constructs (e.g., fear of failure, impulsivity, and neuroticism) can inform the structure of these associations. The current study examined data from 764 young adult twins who completed questionnaires assessing procrastination and personality and structured interviews regarding psychopathology symptoms. Results indicated that procrastination was positively correlated with both internalizing and externalizing latent variables, and that these correlations were driven by shared genetic influences. Moreover, the association between procrastination and internalizing was accounted for by fear of failure and neuroticism, whereas the association between procrastination and externalizing was primarily explained by impulsivity. The role of procrastination in psychopathology is discussed using a framework that highlights common and broadband-specific variance.

  17. Fulfilling environment related international commitments through implementation of multilateral environmental agreements (meas) in pakistan

    2014-01-01

    Multilateral Environmental Agreements (MEAS) help addresses the environmental problem being faced by the international community as a whole. The ultimate goal of reaching MEAs is to realize sustainable development across the globe. According to World Bank (2006), Pakistan's economy loses Rs.365 billion annually to environmental hazards. A key mechanism available under international law for countries to work together on global environmental issues is through MEAs. Pakistan is signatory to several MEAs and has acceded to other non-legally binding instruments, such as Agenda-21, Rio Principles and Johannesburg Plan of Implementation aiming at sustainable development of natural resources. As a party to various Conventions and Protocols, Pakistan has participating in different Conferences of Parties (COPs), Meetings of Parties (MOPs), and international consultative and technical meetings regarding MEAs organized by the United Nations and other international forum. Pakistan has been actively participating in and keeping liaison with institutional elements of each of these MEAs, i.e. COPs, the secretariat, advisory bodies, subsidiary bodies, clearing-house mechanisms, for effective decision making regarding the overall implementation and development of programme of work and strategic plans, budget and the revision of annexes to the treaties. Priorities and objectives of MEAs vary significantly from one international instrument to another while the common aspects include the sustainable development and use of natural resources and the protection of the environment in such a way as to ensure its judicious use. Based on different stages of implementation of these MEAs, the spectrum in priorities of Pakistan has quite broad. Pakistan attaches greater emphasis to crosscutting themes for MEAs that are primarily of a functional nature, such as strengthening of the capacities to meet the country's obligations or responsibilities under these agreements; enhancing coordination

    The analysis on the economic factor environment and the German environmental industry on international competition is faced to methodological limits, since the environmental industry does not present itself as an homogeneous sector. The study is organized in the following chapters: introduction - the importance of environmental industry; classification of environmental and climate protection industry; productivity volume and production structure; international competition for potential environmental protection products; environmental protection industry and innovative performance. Integrated environmental solutions are of increasing significance, avoiding emissions and products and production process from beginning on. All known forecast indicate an expansive market development. In addition the rising prices for crude oil may push the search for innovative solutions to substitute fossil energy sources. The environmental industry should look for globally transferable solutions in order to promote global sustainable growth.

  19. International Approach to Environmental and Lung Health. A Perspective from the Fogarty International Center.

    Glass, Roger I; Rosenthal, Joshua P

    2018-04-01

    The global burden of lung disease is substantial, accounting for an estimated 7.5 million deaths per year, approximately 14% of annual deaths worldwide. The prime illnesses include, in descending order, chronic obstructive pulmonary disease, lung cancer, tuberculosis, acute respiratory infections, asthma, and interstitial lung fibrosis. Key risk factors include smoking, both indoor and outdoor air pollution, and occupational exposures. Although the distribution of both the diseases and the risk factors varies greatly by age, geography, and setting, the greatest burden falls on populations living in low- and middle-income countries. Improvements in these metrics will require major public health interventions to curb smoking; improving air quality both in the community and the household; addressing the ever-present burden of infections, including tuberculosis, flu, and the many agents that cause acute respiratory disease; and identifying and protecting workers from the hazards of exposure to toxic substances. Although research over the years has identified many ways to reduce or prevent the enormous burden of disease, a huge gap exists between what we know and what we can do. This "implementation gap" is the greatest challenge we face in this field today. Research on how best to address and implement the changes needed will require not only biomedical advances to improve treatment but also social, economic, and policy research. We still need to elaborate more effective evidence-based policies and interventions to control tobacco use, address ambient and household air pollution, and improve the prevention and treatment of tuberculosis and acute respiratory infections with vaccines and drugs and reduce exposures to environmental and occupational hazards. Until these efforts receive greater prioritization, the burden of disease is unlikely to diminish a great deal more.

  20. Conservation of 19th and early 20th century oil paintings - in situ studies using the environmental scanning electron microscope

    Full text: Most 19th and early 20th century oil paintings suffer from fading, discolouration, pitting, cracking swelling or the loss of material due to the embrittlement or the extreme friability of the paint layers. As a consequence of this deterioration, they require special care by experienced conservators to ensure their continued preservation. These aging processes are a consequence of (i) chemical interactions between pigments, oils and binders used by the artist and (ii) the action of air, water and ultra-violet irradiation on these materials. The influence of chemical interactions is pertinent for paintings of this era as the industrial revolution brought forth new colourful chemicals that were quickly adopted as pigments with varying success. The conservation of oil paintings requires an understanding of the individual structure of each work of art and what mechanisms underlie its deterioration. This generally involves the need for (i) correct identification of the pigments used by the artist, (ii) a detailed knowledge of the chemical interaction between these pigments, (iii) an understanding of the artist's method of mixing colours and laying paint on the canvas and (iv) a detailed knowledge of the role of the atmosphere, moisture and UV irradiation on painting deterioration. In addition to dealing with the deterioration that occurs within the painting, conservators spend a large portion of their time correcting earlier failed conservation attempts. Most oil paintings from this era are valuable from an artistic or historic perspective and only an extremely small sample may be excised from the work, hence microscopy is an indispensable technique in art preservation. Optical microscopy is the core analysis technique used, however, in recent years a limited number of conservators have begun to use Environmental scanning electron microscopy (ESEM) technology to examine paint layers to take advantage of the accurate and rapid identification of elements present

  1. An overview of international institutional mechanisms for environmental management with reference to Arctic pollution

    International Nuclear Information System (INIS)

    Perkins, Patricia E.

    1994-01-01

    Evidence is mounting of the environmental impact in the Far North of economic and industrial activity elsewhere in the world. While the sources of pollutants found in the Arctic are many and widespread, it is up to just a few countries - notably Canada, the former Soviet Union, Finland, Norway and Greenland - to assess the damage and deal with the impacts. This paper discusses the issue of Arctic pollution in the context of trends in world economic growth, globalization of economic activity, international trade and related institutional arrangements (such as trade and environmental agreements). The importance of tracing the sources of particular contaminants is stressed; this is a first step towards internalization of environmental costs of production, and is also politically a key in efforts to control emissions. Trade and investment agreements commonly discuss rules for cross-border flows of goods, services, personnel and investment capital, as well as matters specific to particular economic sectors. Cross-border flows of pollutants and other 'bads' also merit detailed sectoral attention. This linkage would make explicit the connections between production and pollution (making possible the 'polluter pays' approach), and also widen the scope for redistribution of economic resources to equilibrate the situation (via trade and investment measures, among others) if flows of goods are related directly to flows of 'bads'. The paper examines the outlook for addressing Arctic pollution via international environmental agreements (along the lines of the Basel Convention, the Montreal Protocol, CITES, etc.), existing and future trade agreements (such as GATT), or new institutional approaches

    The challenges faced by states seeking to implement Environmental Remediation works are many. To this end, the International Atomic Energy Agency attempts to provide assistance and guidance to Member States wherever possible. This review article provides a brief overview of these challenges and highlights the international sources of financial and implementation support discussed at an international conference on the topic in Astana, Kazakhstan in 2009. The conference concluded the importance of institutional structures as a pre-requisite for remediation work, recognized privatization as a useful but limited financing tool for remediation and illustrated the need for better coordination between international funding organizations to reduce overlap and optimization of resources to secure the best outcomes.

    1995-01-01

    Plasma technology is an extremely versatile and powerful means of obtaining very high temperatures that can be used in a variety of environmental situations. Since most types of waste products and contaminants can be treated effectively and efficiently, plasma systems have been developed to address the disposal and annihilation domestic of medical, hazardous, radioactive, military, and miscellaneous wastes. Plasma technologies can also be implemented to recycle and recover usable materials from metallic wastes. The International Symposium on Environmental Technologies: Plasma Systems and Applications was held at the Omni Hotel in Atlanta, Georgia on October 8--12, 1995 to bring together a large group of technical experts working on the use of plasma for solving environmental problems. The Symposium is a sequel to the 1994 Metatechnies Conference on Stabilization and Volarization of Ultimate Waste by Plasma Processes that was held in September of 1994 at Bordeaux Lac, France. The proceedings to this second international conference contain the written contributions from eleven sessions and are published in two volumes. A total of 65 papers address the use of plasma systems for environmental applications and include topics concerning the development and use of innovative technologies for waste treatment, environmental remediation, recycling, characterization of the plasma and solid residue, off-gas analyses, as well as case studies and regulatory policies

    This investigation evaluated a multilevel model of dispositional and environmental factors contributing to the development of internalizing problems from preschool-age to school-age. In a sample of 375 families (185 daughters, 190 sons) drawn from three independent samples, preschoolers' behavioral inhibition, cortisol and gender were examined as moderators of the links between mothers' negative parenting behavior, negative emotional characteristics, and socioeconomic status when children were 3.95 years, and their internalizing problems when they were 8.34 years. Children's dispositional characteristics moderated all associations between these environmental factors and mother-reported internalizing problems in patterns that were consistent with either diathesis-stress or differential-susceptibility models of individual-environment interaction, and with gender models of developmental psychopathology. Greater inhibition and lower socioeconomic status were directly predictive of more teacher reported internalizing problems. These findings highlight the importance of using multilevel models within a bioecological framework to understand the complex pathways through which internalizing difficulties develop.

    Japan as an ISO member country identifies the state of discussions in the environmental management standard deliberation committee at ISO. Investigations were performed on international standardization of environmental management systems for the purpose of participating and cooperating in preparing and establishing international standards related to environmental management, and playing part in working, solving and improving environmental problems. Under the circumstances that environmental problems are drawing worldwide interest, the International Organization for Standardization (ISO) has been carrying out since 1993 deliberations on environmental management standards to institutionalize environmental management rules to check effects of business activities on the environment. The International Organization for Standardization/Environmental Management Technical Committee (ISO/TC207) was installed, at which series number of 1400 order was allotted for environmental management related standards, and major standards have come to a final stage of standard formulation at the TC207 Oslo conference in June 1995. In Japan, the Ministry of International Trade and Industry has established an environmental management standard deliberation committee composed of people of experience or academic standing to advance discussions on how the environmental management should be in business entities through deliberations on ISO standards.

    Mean-levels of thin-ideal internalization increase during adolescence and pubertal development, but it is unknown whether these phenotypic changes correspond to developmental changes in etiological (i.e., genetic and environmental) risk. Given the limited knowledge on risk for thin-ideal internalization, research is needed to guide the identification of specific types of risk factors during critical developmental periods. The present twin study examined genetic and environmental influences on thin-ideal internalization across adolescent and pubertal development. Participants were 1,064 female twins (ages 8-25 years) from the Michigan State University Twin Registry. Thin-ideal internalization and pubertal development were assessed using self-report questionnaires. Twin moderation models were used to examine if age and/or pubertal development moderate genetic and environmental influences on thin-ideal internalization. Phenotypic analyses indicated significant increases in thin-ideal internalization across age and pubertal development. Twin models suggested no significant differences in etiologic effects across development. Nonshared environmental influences were most important in the etiology of thin-ideal internalization, with genetic, shared environmental, and nonshared environmental accounting for approximately 8%, 15%, and 72%, respectively, of the total variance. Despite mean-level increases in thin-ideal internalization across development, the relative influence of genetic versus environmental risk did not differ significantly across age or pubertal groups. The majority of variance in thin-ideal internalization was accounted for by environmental factors, suggesting that mean-level increases in thin-ideal internalization may reflect increases in the magnitude/strength of environmental risk across this period. Replication is needed, particularly with longitudinal designs that assess thin-ideal internalization across key developmental phases. © 2014 Wiley

  16. Domestic Environmental Policy and International Factor Mobility: A General Equilibrium Analysis

    1995-01-01

    This paper studies the conditions under which a green tax reform not only benefits the environment but also enhances the efficiency of the tax system. The focus is on the consequences of international factor mobility for the scope of a double dividend. The investigation of the double-dividend claim is based on a general equilibrium model of a stylised small open economy. The simulations of equal-yield tax reform scenarios indicate that an environmental tax on consumption yields a double divid...

    Somatic embryogenesis is an important biotechnological technique which can be used in studies associated with environmental stress. Four embryogenic cell lines of Norway spruce were grown on media enriched with copper and arsenic in concentration ranges 50-500 μM and 10-50 μM, respectively. The effects were observed during subsequent stages of somatic embryogenesis, the characteristics evaluated being proliferation potential, average number of somatic embryos obtained per g/fresh weight, morphology of developed somatic embryos, metal uptake, and microanalysis of macro- and micronutrients uptake. Copper and arsenic at higher concentrations significantly reduced the growth of early somatic embryos. In almost all treatments, the cell line V-1-3 showed the best performance compared with the other lines tested. Environmental scanning electron microscopy was used to visualize and identify morphological abnormalities in the development of somatic embryos. Abnormalities observed were classified into several categories: meristemless somatic embryos, somatic embryos with disrupted meristem, reduced number of cotyledons, single cotyledon and fused cotyledons. With the application of a low temperature method for the environmental scanning electron microscope, samples were stabilized and whole meristems could be investigated in their native state. As far as we are aware, this is the first report of the effect of copper and arsenic during the process of somatic embryogenesis and the first to evaluate the content of macro and micronutrients uptake in Norway spruce.

    This paper integrates themes from psychology and economics to analyze pro-environmental behavior. Increasingly, both disciplines share an interest in understanding internal and external influences on behavior. In this study, we analyze data from a mail survey of participants and non-participants in a premium-priced, green electricity program. Internal variables consist of a newly developed scale for altruistic attitudes based on the Schwartz norm-activation model, and a modified version of the New Ecological Paradigm scale to measure environmental attitudes. External variables consist of household income and standard socio-demographic characteristics. The two internal variables and two external variables are significant in a logit model of the decision to participate in the program. We then focus on participants in the program and analyze their specific motives for participating. These include motives relating to several concerns: ecosystem health, personal health, environmental quality for residents in southeastern Michigan, global warming, and warm-glow (or intrinsic) satisfaction. In a statistical ranking of the importance of each motive, a biocentric motive ranks first, an altruistic motive ranks second, and an egoistic motive ranks third. (author)

  20. The effects of R&D investments in international environmental agreements with asymmetric countries

    2015-01-01

    The paper examines the stability of international environmental agreements (IEAs) in a dynamic context where abatement levels are associated with the stock pollutant evolution. We underline two meaningful aspects of this matter. Firstly, we consider asymmetry among countries, dividing them in two types: developed countries that have a considerable environmental awareness and developing ones that pay a less attention to environmental preservation. Secondly, we introduce a positive externality in the cooperation where countries coordinate their R&D activities sharing the investments in order to avoid duplication of green activities. Otherwise, the non-cooperators support completely their R&D investments for clean technologies. These two aspects encourage the formation of stable coalitions till to determine conditions for which also the grand coalition is stable.

    1993-10-01

    The Prague Conference on nuclear waste management and environmental remediation provided extensive interchange of ideas and insight into new technologies and management approaches throughout the world. A variety of environmental remediation technologies have potential application to Department of Energy facilities; others illustrate pitfalls to be avoided. This paper presents the highlights from the first environmental remediation (ER) technical program in the American Society of Mechanical Engineers' series of international nuclear waste management conferences. This program covers ER technologies, decontamination and decommissioning (D ampersand D) technologies and experience, ER site characterization and modeling, management of and results from actual clean up actions, and data on several major international environmental problems. Focusing on direct benefits to the Department of Energy's (DOE) ER Program, this paper summarizes pertinent technical information, identifies useful technical papers, lists key technical contacts, and identifies specific actions to obtain additional information. US attendance at meetings like this is normally quite limited compared to attendance at North American meetings. The purpose of this paper then is to increase general awareness of this meeting in US technical circles and to broadly disseminate key information to US ER programs and contractors. To do this, the paper is organized to present background information on the conference itself, document the beneficial technical information, and outline ongoing information exchange activities

    The aim of the present work was to compare the elastic properties and internal structure of 4 different CAD/CAM chairside materials, by the method of Scanning Impulse Acoustic Microscopy (SIAM). Four chairside CAD/CAM materials with different structures from hybrid ceramic (VITA Enamic, VITA Zahnfabrik), feldspatic ceramic (VITABlocs Mark II, VITA Zahnfabrik), leucite glass-ceramic (IPS Empress CAD, Ivoclar Vivadent) and PMMA (Telio CAD, Ivoclar Vivadent) were examined by Scanning Impulse Acoustic Microscope (SIAM). The results of micromorphological research of CAD/CAM chairside materials using SIAM method showed differences between the internal structures of these materials. The internal structure of feldspatic and glass-ceramic samples revealed the presence of pores with different sizes, from 10 to 100 microns; the structure of polymer materials rendered some isolated defects, while in the structure of hybrid material, defects were not found. Based on the results obtained from the present study, in cases of chairside production of dental crowns, it would be advisable to give preference to the blocks of hybrid ceramics. Such ceramics devoid of quite large porosity, glazing for CAD/CAM crowns made from leucite glass-ceramic and feldspatic ceramic may be an option. For these purposes, commercially available special muffle furnace for clinical and laboratory individualization and glazing of ceramic prostheses were provided. Further studies are needed to confirm the evidence emerging from the present research.

    The purpose of this book (monograph) is to describe various environmental consequences of NATO bombing in Federal Republic of Yugoslavia (FRY) from March 24 to June 10, 1999, and to give some recommendations for the environmental recovery of Yugoslavia. During the NATO bombing campaign in 1999, 78 industrial facilities and 45 energy installations were damaged or destroyed, releasing thousands of tons of various carcinogenic, mutagenic and toxic chemicals, including some persistent organic pollutants banned by the Stockholm convention for human use. Over 150,000 tons of oil and oil derivates and 367,000 tons of kerosene were burned, more than 20,000 residential buildings were destroyed, and at least 31,000 rounds of thirty millimeter DU munitions were fired. G17 group has estimated the damage to the infrastructure at over US$30 billion. The monograph is based on the papers presented at the First International Conference on Environmental Recovery of Yugoslavia, Belgrade, September 27 to 30, 2001 (ENRY2001). The conference included 142 presentations by 320 authors from 21 countries as well as three teleconference presentations from the U.S. Environmental Protection Agency(EPA). About 80 papers are included in the presented form, and some papers(about 30) are included in a modified (extended or completed) form. In order to have a more complete coverage in the book of important relevant topics,several contributions not presented at ENRY2001 are also included. An assessment of environmental damage and prospects for environmental remediation are presented. The status of the region up to 1991 (including preexisting ecological characteristics, as well as social and economical development), and the changes between 1991 and 2001 that include the effects of external economic sanctions, civil wars, and the NATO bombing in 1999 are included in the assessments. The ENRY2001 Activity Report and the Conference Conclusions and Recommendations are also included. These reports give a

  5. Combining Environmental and Spatial Discount Rates for Valuation of Assets According to International Financial Reporting Standards

    Full Text Available Application of discount rate in finance and accounting is founded on the concept of time value of money. Discounted cash flow model is widely used for asset valuation under the International Financial Reporting Standards (in abbreviation, IFRS. The discount rate applied in valuation models normally is the best rate of return that investors would earn alternative investments. With emergence of ecological economics as a separate branch of economics, the concept of ecological (or in other words, environmental discount rate has been elaborated. Muller (2013 in his paper ‘The Discounting Confusion: an Ecological Economics Perspective’, argues that traditional discounting can undermine long-term sustainability of the economy. In his work, Frank G. Muller considered adjusting the traditional discount rate in order to arrive at an environmental discount rate, which would help to ensure the sustainability of the economy. Hannon (2001 and Perrings (2001 in their paper ‘An Introduction to Spatial Discounting’ consider another variation of the discount rate - spatial discount rate. Spatial discount rate represents the rate at which the diffusion of environmental effects of economic activities is discounted over space. By February 2016, neither the application of environmental nor spatial discount rates under IFRS has been considered. The purpose of this paper is to analyse the implications that environmental and spatial discounting would have for the application of discounted cash flow model according to IFRS. The research methods applied are methods of economic analysis and synthesis.

    A reproducible way to transfer a single crystalline sample into a gas environmental cell holder for in situ transmission electron microscopic (TEM) analysis is shown in this study. As in situ holders have only single-tilt capability, it is necessary to prepare the sample precisely along a specific zone axis. This can be achieved by a very accurate focused ion beam lift-out preparation. We show a step-by-step procedure to prepare the sample and transfer it into the gas environmental cell. The sample material is a GaP/Ga(NAsP)/GaP multi-quantum well structure on Si. Scanning TEM observations prove that it is possible to achieve atomic resolution at very high temperatures in a nitrogen environment of 100,000 Pa.

    Advances in atomic resolution Environmental (Scanning) Transmission Electron Microscopy (E(S)TEM) for probing gas-solid catalyst reactions in situ at the atomic level under controlled reaction conditions of gas environment and temperature are described. The recent development of the ESTEM extends the capability of the ETEM by providing the direct visualisation of single atoms and the atomic structure of selected solid state heterogeneous catalysts in their working states in real-time. Atomic resolution E(S)TEM provides a deeper understanding of the dynamic atomic processes at the surface of solids and their mechanisms of operation. The benefits of atomic resolution-E(S)TEM to science and technology include new knowledge leading to improved technological processes with substantial economic benefits, improved healthcare, reductions in energy needs and the management of environmental waste generation. xml:lang="fr"

  8. Scanning personnel for internal deposition of radioactive material with personnel contamination whole body friskers and portal monitors

    Lobdell, J.L.

    1996-01-01

    The potential for using personnel contamination devices such as whole body friskers and portal monitors for internal contamination monitoring was evaluated. Internally deposited radioactive material is typically determined with whole body counting systems. Whole body counts have traditionally been performed on personnel when they report for work, on a periodic basis (i.e., annually), when an uptake is suspected, and on termination. These counts incur significant expense. The monitored personnel pass through whole body friskers and portal monitors daily. This investigation was performed to determine if the external contamination monitors could provide an alternative to the more Costly whole body counting. The ability to detect 1% of a DAC for critical radioisotopes was applied as a detection criteria for this investigation. The results of whole body counts were used to identify the typical internal contamination radionuclides. From this list, the radioisotopes that would be the most difficult to measure were identified. From this review, 60 Co and 131 I were determined to be the critical radionuclides. One percent of a DAC for each isotope was placed, one at a time, in a humanoid phantom. The phantom was placed in the whole body frisker and open-quotes countedclose quotes. The phantom was carried through the portal monitor at a speed equivalent to a person walking through the monitor. Frequency of detection was derived for both systems. Practical aspects of integrating this screening system with traditional internal dosimetry programs are discussed

    The environmental technology is one of the most important growth markets worldwide. In the light of the unique environmental political challenges predictions refer to an expansionary trend towards market development - especially in the international context, with particular emphasis on the climate protection. The companies of the German environmental industry increasingly operate in global markets. A major share of that growth has been developed there. Temporarily, only the foreign market offered expansion opportunities. Even if the companies are not active on the export markets, the companies in the domestic market compete with their international export markets. Insofar, the question of the international competitiveness of the environmental industry is a key issue.

    For the past 16 years, the International Training and Research in Environmental and Occupational Health program (ITREOH) has supported projects that link U.S. academic scientists with scientists from low- and middle-income countries in diverse research and research training activities. Twenty-two projects of varied duration have conducted training to enhance the research capabilities of scientists at 75 institutions in 43 countries in Asia, Africa, Eastern Europe, and Latin America, and have built productive research relationships between these scientists and their U.S. partners. ITREOH investigators and their trainees have produced publications that have advanced basic sciences, developed methods, informed policy outcomes, and built institutional capacity. Today, the changing nature of the health sciences calls for a more strategic approach. Data-rich team science requires greater capacity for information technology and knowledge synthesis at the local institution. More robust systems for ethical review and administrative support are necessary to advance population-based research. Sustainability of institutional research capability depends on linkages to multiple national and international partners. In this context, the Fogarty International Center, the National Institute of Environmental Sciences and the National Institute for Occupational Safety and Health, have reengineered the ITREOH program to support and catalyze a multi-national network of regional hubs for Global Environmental and Occupational Health Sciences (GEOHealth). We anticipate that these networked science hubs will build upon previous investments by the ITREOH program and will serve to advance locally and internationally important health science, train and attract first-class scientists, and provide critical evidence to guide policy discussions.

    The precision of fit of chairside computer-aided design and computer-aided manufacturing (CAD-CAM) complete crowns is affected by digital impression and restorative material. The purpose of this in vitro study was to evaluate by microcomputed tomography (μCT) the marginal and internal adaptation of composite resin and ceramic complete crowns fabricated with 2 different intraoral cameras and 2 restorative materials. Ten extracted human third molars received crown preparations. For each prepared molar, 2 digital impressions were made with different intraoral cameras of the CEREC system, Bluecam and Omnicam. Four groups were formed: LB (Lava Ultimate+Bluecam), EB (Emax+Bluecam), LO (Lava Ultimate+Omnicam), and EO (Emax+Omnicam). Before measuring the precision of fit, all crowns were stabilized with a silicone material. Each unit (crown + prepared tooth) was imaged with μCT, and marginal and internal discrepancies were analyzed. For the 2D analysis, 120 measurements were made of each crown for marginal adaptation, 20 for marginal discrepancy (MD), and 20 for absolute marginal discrepancy (AMD); and for internal adaptation, 40 for axial space (AS) and 40 for occlusal space (OS). After reconstructing the 3D images, the average internal space (AIS) was calculated by dividing the total volume of the internal space by the contact surface. Data were analyzed with 2-way ANOVA and quantile regression. Regarding marginal adaptation, no significant differences were observed among groups. For internal adaptation measured in the 2D evaluation, a significant difference was observed between LO and EO for the AS variable (Mann-Whitney test; POmnicam, and composite resin crowns showed less discrepancy than did ceramic crowns. The marginal adaptations assessed in all groups showed values within the clinically accepted range. Moreover, the composite resin blocks associated with the Bluecam intraoral camera demonstrated the best results for AIS compared with those of the other groups

    A wealth of evidence documents associations between various aspects of the rearing environment and later development. Two evolutionary-inspired models advance explanations for why and how such early experiences shape later functioning: (a) the external-prediction model, which highlights the role of the early environment (e.g., parenting) in regulating children's development, and (b) the internal-prediction model, which emphasizes internal state (i.e., health) as the critical regulator. Thus, by using data from the NICHD Study of Early Child Care and Youth Development, the current project draws from both models by investigating whether the effect of the early environment on later adolescent functioning is subject to an indirect effect by internal-health variables. Results showed a significant indirect effect of internal health on the relation between the early environment and adolescent behavior. Specifically, early environmental adversity during the first 5 years of life predicted lower quality health during childhood, which then led to problematic adolescent functioning and earlier age of menarche for girls. In addition, for girls, early adversity predicted lower quality health that forecasted earlier age of menarche leading to increased adolescent risk taking. The discussion highlights the importance of integrating both internal and external models to further understand the developmental processes that effect adolescent behavior.

    Highlights: ► Dynamic flow models are presented for remanufactured, reused or recycled products. ► Early loss and stochastic return are included for fast and slow cycling products. ► The reuse-to-input flow ratio (Internal Cycle Factor, ICF) is determined. ► The cycle rate, which is increasing with the ICF, monitors eco-performance. ► Early internal cycle losses diminish the ICF, the cycle rate and performance. - Abstract: Dynamic annual flow models incorporating consumer discard and usage loss and featuring deterministic and stochastic end-of-cycle (EOC) return by the consumer are developed for reused or remanufactured products (multiple cycle products, MCPs), including fast and slow cycling, short and long-lived products. It is shown that internal flows (reuse and overall consumption) increase proportionally to the dimensionless internal cycle factor (ICF) which is related to environmental impact reduction factors. The combined reuse/recycle (or cycle) rate is shown capable for shortcut, albeit effective, monitoring of environmental performance in terms of waste production, virgin material extraction and manufacturing impacts of all MCPs, a task, which physical variables (lifetime, cycling frequency, mean or total number of return trips) and conventional rates, via which environmental policy has been officially implemented (e.g. recycling rate) cannot accomplish. The cycle rate is shown to be an increasing (hyperbolic) function of ICF. The impact of the stochastic EOC return characteristics on total reuse and consumption flows, as well as on eco-performance, is assessed: symmetric EOC return has a small, positive effect on performance compared to deterministic, while early shifted EOC return is more beneficial. In order to be efficient, environmental policy should set higher minimum reuse targets for higher trippage MCPs. The results may serve for monitoring, flow accounting and comparative eco-assessment of MCPs. They may be useful in identifying

    2013-01-01

    Full Text Available The paper contains an analysis of choice of law rules in the field of non-contractual liability for damage caused to environment in national legislations of European countries as well as in Private International Law of the European Union. Before the adoption of Regulation of the European Parliament and of the Council on the law applicable to non-contractual obligations (Rome II, special choice of law rules for environmental torts existed in a small number of European national legal orders. This is the fact that gives the rule contained in Article 7 of the Rome II Regulation a particular importance. From the Serbian Private International Law perspective, the significance of that provision is highlighted by the fact that the working draft of the new Serbian Private International Law Act has strictly followed the choice of law rule envisaged by the European legislator for environmental damage. For that reason, a significant part of the paper is dedicated to analysis of said rule, to its interpretation and potential problems which its application could create.

    Billions of dollars are being invested to achieve environmental compliance at the Hanford Site. The 30-yr-plan for the Site calls for remediation and restoration followed by rampdown and closure of the US Department of Energy's (DOE) mission at the Site. The investment of the Federal government during this restoration period provides a real opportunity to go beyond the cleanup mission and convert the Site's assets to other uses that benefit the region, nation, and world. The International Environmental Institute (Institute) was created to help realize this opportunity. This is accomplished by utilizing the assets of the Site -- it's land, equipment, facilities, technologies, and people -- to achieve economic growth and worldwide spinoff benefits from the Hanford investment. The Institute is developing new ways of getting the private sector involved with the Hanford Site. We are working with local and state governments, academia, and the private sector, to jointly develop and commercialize environmental technologies and to redeploy, loan, or lease those assets that are no longer needed by the DOE. The Institute is also interacting with other communities around the world to assess models, issues, and performance measures for successful defense conversion. Through these various worldwide partnerships, the investment in Hanford can be successfully leveraged to help create the desired economic future for the Northwest and environmental industry for the world

    The ITER Project includes design and assessment activities to ensure the safety and environmental attractiveness of ITER and demonstrate that it can be sited in any of the sponsoring Parties with a minimum of site-specific redesign. This paper highlights some of the efforts to develop an international consensus approach for ITER safety design and assessment, including: development of general safety and environmental design criteria; development of quantitative dose-release assessment criteria; development of a radiation protection program; waste characterization; and development of safety analysis guidelines. The high level of interaction, cooperation and collaboration between the Joint Central Team and the Home Teams, and between the safety team and designers, and the spirit of consensus that has guided them have resulted in a safe design for ITER and a safety design and assessment that can meet the needs of the potential host countries.

    The settlement of important energy- and environmental-policy issues hoped for in 1992 has not been reached, and 'wait and see' has become the ruling attitude in matters of energy economy. The investments planned for eastern Germany are stagnating, and the German-German integration suffers from political uncertainties in addition to its market risks. The utilities have been left without the necessary reliable long-term data. Disillusionment also prevails in the European integration process and at the international level. (orig.) [de

    The authors report the application of the internal standard method to the simultaneous determination of trace elements in environmental reference materials. The standard soil material used was IAEA CRM Soil-5. The power plant fly ash reference used was NBS SRM-1633a. Fifteen target elements, including As, Ba and Ce, were determined. Internal standards were supplied by six elements, including Na and Mg. Although there were several interfering elements, their effect could be eliminated by utilizing more than one gamma-ray peak and carrying out appropriate corrections. The values determined for most of the target elements were well within the certified range. Measured concentrations were of the orders of 10 to 1000 ..mu..g/g. 6 references, 2 figures, 5 tables.

    Presently, all the organizations involved with nuclear activities must be one step ahead of what happens in the specific activity areas in order to avoid surprises, to guarantee their activity continuity and the objective extents, and taking into account the external environment influence exercised by the organization on their activities. So, it is necessary a continuous follow up of their transformations. This paper aims to structure a model of the environmental monitoring system oriented to the strategic planning of the Brazilian Nuclear Energy Commission, as function of that new informational needs viewing the fulfilment of that observed gap.

  10. Multi-Level Integration of Environmentally Perturbed Internal Phenotypes Reveals Key Points of Connectivity between Them

    Full Text Available The genotype and external phenotype of organisms are linked by so-called internal phenotypes which are influenced by environmental conditions. In this study, we used five existing -omics datasets representing five different layers of internal phenotypes, which were simultaneously measured in dietarily perturbed mice. We performed 10 pair-wise correlation analyses verified with a null model built from randomized data. Subsequently, the inferred networks were merged and literature mined for co-occurrences of identified linked nodes. Densely connected internal phenotypes emerged. Forty-five nodes have links with all other data-types and we denote them “connectivity hubs.” In literature, we found proof of 6% of the 577 connections, suggesting a biological meaning for the observed correlations. The observed connectivities between metabolite and cytokines hubs showed higher numbers of literature hits as compared to the number of literature hits on the connectivities between the microbiota and gene expression internal phenotypes. We conclude that multi-level integrated networks may help to generate hypotheses and to design experiments aiming to further close the gap between genotype and phenotype. We describe and/or hypothesize on the biological relevance of four identified multi-level connectivity hubs.

    A better understanding of key processes in the aquatic environment, responsible for its future development and its protection, were at the forefront of the IAEA's International Conference on Isotopes in Environmental Studies - AQUATIC FORUM 2004 convened in Monaco from 25 to 29 October 2004, which was the most important gathering of the year of isotope environmental scientists. Over 320 experts from 60 IAEA Member States and 6 international organizations delivered 185 oral presentations in 6 plenary and 31 parallel sessions and made 130 poster presentations. The conference reviewed the present state of the art isotopic methods for investigation of the aquatic environment. The main conference subjects considered were: (i) behaviour, transport and distribution of isotopes in the aquatic environment; (ii) climate change studies using isotopic records in the marine environment; (iii) groundwater dynamics, modelling and management of freshwater sources; (iv) important global projects, such as WOCE, WOMARS, SHOTS, GEOTRACES; (v) joint IAEA-UNESCO submarine groundwater investigations in the Mediterranean Sea, the Southwest Atlantic and Pacific Oceans; (vi) new trends in radioecological investigations, concentrating on the protection of marine biota against radioactive contamination; (vii) transfers in analytical technologies from bulk analyses to particle and compound specific analyses of environmental samples; (viii) development of new isotopic techniques, such as AMS and ICPMS, and their successful applications in environmental studies; and many other exciting topics which were presented and discussed during the Conference. Four workshops were held simultaneously: - ATOMS-Med Workshop - development of a project proposal for oceanographic investigations in the Eastern Mediterranean. - El Nino - Research Co-ordination Meeting of the new IAEA Coordinated Research Project investigating climate change using isotopic records in the marine environment. - CELLAR Workshop

    Full Text Available Background: This study aimed to investigate sternal healing over time and the incidence of poor sternal healing in patients undergoing coronary artery bypass graft (CABG surgery using bilateral internal thoracic arteries. Methods: This study enrolled 197 patients who underwent isolated CABG using skeletonized bilateral internal thoracic arteries (sBITA from 2006 through 2009. Postoperative computed tomography (CT angiography was performed on all patients at monthly intervals for three to six months after surgery. In 108 patients, an additional CT study was performed 24 to 48 months after surgery. The axial CT images were used to score sternal fusion at the manubrium, the upper sternum, and the lower sternum. These scores were added to evaluate overall healing: a score of 0 to 1 reflected poor healing, a score of 2 to 4 was defined as fair healing, and a score of 5 to 6 indicated complete healing. Medical records were also retrospectively reviewed to identify perioperative variables associated with poor early sternal healing. Results: Three to six months after surgery, the average total score of sternal healing was 2.07±1.52 and 68 patients (34.5% showed poor healing. Poor healing was most frequently found in the manubrium, which was scored as zero in 72.6% of patients. In multivariate analysis, the factors associated with poor early healing were shorter post-surgery time, older age, diabetes mellitus, and postoperative renal dysfunction. In later CT images, the average sternal healing score improved to 5.88±0.38 and complete healing was observed in 98.2% of patients. Conclusion: Complete sternal healing takes more than three months after a median sternotomy for CABG using sBITA. Healing is most delayed in the manubrium.

  13. Signalling in international environmental agreements. Using pre-agreement emission level as a signalling device

    Steiner, U.

    1997-12-31

    This paper addresses the question about strategic incentives in international environmental agreements and tries to give a positive description of how the design of the agreement influences the strategic behaviour of potential participants before they enter the treaty. A common feature of the design of agreements is that the reduction obligations (RO) are made contingent on a pre-agreement or baseline emission. As it is assumed that countries posses better information about their reduction costs than does the international body in charge of deciding the RO, countries might have incentives to signal higher costs by increasing their baseline emission, and thereby reducing the costs of entering the agreement. The appropriate analytical framework is to use a signalling game approach, where the pre-agreement emission level conveys information about the privately informed country`s reduction cost. In this paper two types of agreement design are considered, one with uniform obligations, and one with differentiated obligations. This enables us to make a comparison between two different reduction regimes. The result is that the predicted outcomes vary with regard to both the environmental effectiveness and the associated expected costs for the participating countries. This means that when private information is considered, the anticipation of a given institutional framework has significant impact on the resulting distortion of the total emission level, highlighting the necessity of taking this into consideration when future designs are proposed.

    The Department of Energy Office of Environmental Management (DOE-EM) Office of Engineering and Technology is responsible for implementing EM's international cooperative program. The Office of Engineering and Technology's international efforts are aimed at supporting EM's mission of risk reduction and accelerated cleanup of the environmental legacy of the nation's nuclear weapons program and government-sponsored nuclear energy research. To do this, EM pursues collaborations with government organizations, educational institutions, and private industry to identify and develop technologies that can address the site cleanup needs of DOE. Currently, DOE-EM is performing collaborative work with researchers at the Khlopin Radium Institute (KRI) and the SIA Radon Institute in Russia and the Ukraine's International Radioecology Laboratory (IRL). Additionally, a task was recently completed with the Nuclear Engineering Technology Institute (NETEC) in South Korea. The objectives of these collaborations were to explore issues relating to high-level waste management and to investigate technologies that could be leveraged to support EM site cleanup needs. The initiatives in Russia and South Korea were aimed at evaluating and advancing technologies to support U.S. high-level waste vitrification initiatives. The work at KRI was targeted at improving the throughput of current vitrification processes by increasing melting rate and/or waste loading. The objectives of the efforts conducted at SIA Radon and NETEC were to evaluate advanced melter technologies to make dramatic increases in waste loading and throughput. The collaborative effort conducted with the IRL in the Ukraine has the following objectives: - Assess the long-term impacts to the environment from radiation exposure within the Chernobyl Exclusion Zone (ChEZ); - Provide information on remediation guidelines and ecological risk assessment within radioactively contaminated territories based on the results of long-term field

    2015-01-01

    The present work provides an international comparison of the energy intensity and the carbon dioxide intensity in road transport for a group of 90 countries over the period 1980–2012. This paper attempts to perform a comparative analysis to find the most appropriate mapping of the energy performance in road transport taking into account the three dimensions of sustainable energy development, namely road transport-related energy consumption, economic growth and carbon dioxide emissions. An important result of the study is the inverse relationship between energy efficiency and environmental efficiency. Through the calculated Theil coefficient, our empirical findings highlight the existence of spatial and temporal disparities between countries. In 2012, Tunisia occupies the 48th and the 38th rank respectively in terms of energy and environmental efficiency. Based on a general index of energy performance in the road transport sector, it is deemed to have a medium–high energy performance by occupying the 34th rank. The study shows the importance of enhancing a number of policies for the road transport system through the joint improvement of the fuel price policy, of the road infrastructure policy and of the fuel-efficient road vehicles policy, in order to maintain sustainable energy road transport. - Highlights: • The paper presents an international comparative analysis of the energy performance. • The road transport is analyzed for a group of 90 countries over the period 1980–2012. • There is no convergence between energy and environmental efficiencies. • Tunisia has a medium-high energy performance by occupying the 34th rank in 2012. • The findings show the importance of enhancing some policies for the road transport.

    Environmental problems have gone, when it comes to their discussion, beyond the purely scientific arena, to being also discussed at a political stage, giving birth to what has been called political ecology. The dimensions of the problem, as well as its global nature, have created some sort of political institutionalism, which ranges from international organisms, UNO, World Bank; etc, to very local organizations. This approach has two conceptual positions al its base: environmentalism, which gives preeminence to man over nature, with its trends of Eco-development which leans on local ecology and culture; and sustainable development which leans on economic growth which should generate resources to alleviate environmental damage and social inequities. On the other hand all the unbreakable links with the other living beings and the physical surroundings. It also has two trends: Deep Ecology which advocates respect for nature as a systemic unit within which man is immerse; and Global Eco-ethics which stand for political action that departs from accepting current man's responsibility towards the forthcoming human societies, whose well-being will depend on our respect for natural dynamics

  19. Sharing R&D investments in international environmental agreements with asymmetric countries

    2018-05-01

    This paper studies the coalition formation and the stability of the International Environmental Agreements (IEAs) in a pollution abatement dynamic model. We point out two meaningful aspects of this topic. Firstly, we consider asymmetry among countries, dividing them into two types: developed countries with a considerable environmental awareness and developing ones that pay less attention to environmental preservation. In addition, the former have a high-technology industry that allows for a unit abatement cost lower than the latter, and that are characterized by a labour-intensive industrial structure. Secondly, we introduce a positive externality in the cooperation by considering the R&D investment as two costs, namely the research investment and the developing cost. We assume that countries can coordinate their R&D activities by sharing their fixed research investments in order to avoid duplication of green activities. Moreover, by collaborating developing efforts, cooperators benefit from a reduction of a unit abatement cost higher than defectors. On the other hand, although non-cooperators completely support R&D investments for clean technologies, they realize lower abatements and benefits of a spillover effect due to development investments realized by cooperators. These two aspects could encourage the formation of stable coalitions.

    Fish scale has the potential to be a rapid biomarker due to its structure and high possibility to come into contact with any pollutant in the aquatic environment. The scale structure consists of osteoblastic cells and other bone materials such as collagen where it is possible to form a molecular complex with heavy metals such as aluminum and iron. Hence, aluminum and iron in water could possibly destroy the scale material and marked as a scale deformation that quantitatively could be analyzed by comparing it to the normal scale structure. Water sampling and fish cage experiment were performed between June and July 2011 in Porong river which represented the water body that has high aluminum and iron contamination. The filtered water samples were preserved and extracted using the acid-mixture procedure prior to measurement of the aluminum and iron concentrations using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), while samples for total suspended solid (TSS) analysis were kept at 4 °C in cool-boxes. The scales were cleaned with sterile water, then dehydrated in 30, 50, 70, and 90% ethanol and dried on filter papers. They were then mounted on an aluminum stub and coated with gold in a sputter coater prior to Scanning Electron Microscope (SEM) observation. According to the SEM analysis, it was found that there were several deformations on the scale samples taken from sites that have high concentrations of aluminum and iron i.e. the increasing number of pits, deformation and decreasing number of spherules and ridges while the control scale exhibited the normal features. However, the site with higher TSS and pH indicated lower aluminum effect. A moderate correlation was found between the number of pits with aluminum (r=0.43) and iron (r=0.41) concentrations. Fish scale deformation using SEM analysis can potentially be a rapid biomarker in aquatic monitoring of aluminum and iron contamination. However, the measurement must be accompanied by pH and

    The production of electricity creates environmental insults whose costs are not fully reflected in the prices paid by consumers for electricity services. Failure to incorporate these external costs leads to economically inefficient production and consumption decisions. The present work reviews two related efforts to address this market distortion. The first concerns progress in estimating the uninternalized environmental costs of electricity production. The second concerns market-based approaches to internalizing these costs in electricity production and consumption decisions. 10 tabs.; 41 refs

    Long-term settlement magnitude is influenced by changes in external and internal factors that control the microbiological activity in the landfill waste body. To improve the understanding of settlement phenomena, it is instructive to study lysimeters filled with MSW. This paper aims to understand the settlement behavior of MSW by correlating internal and external factors that influence waste biodegradation in a lysimeter. Thus, a lysimeter was built, instrumented and filled with MSW from the city of Campina Grande, the state of Paraíba, Brazil. Physicochemical analysis of the waste (from three levels of depth of the lysimeter) was carried out along with MSW settlement measurements. Statistical tools such as descriptive analysis and principal component analysis (PCA) were also performed. The settlement/compression, coefficient of variation and PCA results indicated the most intense rate of biodegradation in the top layer. The PCA results of intermediate and bottom levels presented fewer physicochemical and meteorological variables correlated with compression data in contrast with the top layer. It is possible to conclude that environmental conditions may influence internal indicators of MSW biodegradation, such as the settlement.

    Full Text Available While the greatest potential for environmental displacement occurs in poorer nations, internal displacement has resulted from environmental change and disasters in the United States; and climate change will likely amplify this movement. I describe how environmental displacement is a policy drift that reduces the effectiveness of current welfare state policies to protect US populations from the risk of impoverishment. Evidence from previous disasters indicates environmental displacees have particular assistance needs. I identify the four main assistance needs in my Environmental Displacement and Resilience Model then use this model to evaluate whether current policies address housing, finances, health, and discrimination needs of those displaced. My analysis highlights a gap between the country’s response to disasters and the current welfare state social safety nets. Without disaster and welfare policy changes environmental displacement will continue to be a policy drift that leave displacees vulnerable to social and economic marginalization. Mientras que el mayor potencial de desplazamientos por causas medioambientales se da en los países más pobres, en los Estados Unidos se ha producido un desplazamiento interno como resultado de cambios ambientales y desastres; y es probable que el cambio climático aumente estos movimientos. Se describe cómo los desplazamientos por causas ambientales suponen un fallo político que reduce la eficacia de las actuales políticas del estado de bienestar que se deben desarrollar para proteger a la población de Estados Unidos contra el riesgo de empobrecimiento. Evidencias de desastres anteriores indican que los desplazados por causas medioambientales tienen necesidades de asistencia especiales. Se identifican las cuatro necesidades de asistencia principales que recoge Modelo de Desplazamiento Medioambiental y Resiliciencia de la autora, para después usar este modelo para evaluar si las políticas actuales

A Statement of Intent was recently signed between DOE-EM and the U.K. Nuclear Decommissioning Authority (NDA) to work cooperatively on areas of mutual interest. Under this umbrella, discussions were held with NDA representatives to identify potential areas for collaboration. Information and technical exchanges were identified as near-term actions to help meet the objectives of the Statement of Intent. Technical exchanges in identified areas are being pursued in FY09.

    When optimizing the performance of complex systems, a logical area for concern is improving the efficiency of useful energy. The energy available for a system to perform work is defined as a system's energy content. Interactions between a system's subsystems and the surrounding environment can be accounted for by understanding various subsystem energy efficiencies. Energy balance of reactants and products, and enthalpies and entropies, can be used to represent a chemical process. Heat transfer energy represents heat loads, and flow energy represents system flows and filters. These elements allow for a system level energy balance. The energy balance equations are developed for the subsystems of the Environmental Control and Life Support (ECLS) system aboard the International Space Station (ISS). The use of these equations with system information would allow for the calculation of the energy efficiency of the system, enabling comparisons of the ISS ECLS system to other systems as well as allows for an integrated systems analysis for system optimization.

    One of the principal objectives of the International Technology Exchange Program (ITEP) is the exchange of waste management and environmental restoration (WM/ER) technologies between the US and other nations. The current emphasis of ITEP is the transfer of technologies to the US that could provide better, faster, cheaper, or safer solutions to the needs of the DOE complex. The 10 candidate technologies that have been identified thus far by ITEP are discussed. The highlights of preliminary evaluations of these technologies through a systems approach are also described. The technologies have been evaluated by a screening process to determine their applicability to the leading WM/ER needs of the DOE complex. The technologies have been qualitatively compared with the known or anticipated capabilities of domestic, base case technologies

    Considerations on priorities are presented in connection with the broad development of bilateral and multilateral international cooperation to solve global environmental problems. Emphasis is placed on the problem of global climate change, on optimizing the global climate observation system, and on substantiating the (1) inadequacy of the 'greenhouse' stereotype of global climate warming which has long predominated in Russian cooperation programs, and (2) the need to realize real climatic prorities (the role of biosphere dynamics, the interaction of atmosphere and ocean, cloud cover and radiation, the colloidal nature of the atmosphere, etc.). The thermal balance of the earth and the dynamics of the biosphere are considered as the key problems of global ecodynamics. Particular attention is given to socio-economic aspects of ecology. 62 refs.

  15. Harmonization of health related environmental measurements using nuclear and isotopic techniques. Proceedings of an international symposium

    1997-01-01

    One of the particular strengths of nuclear methods is in analytical quality assurance, including the validation of analytical methods and the development of new analytical reference materials. These methodologies are therefore helping to harmonize the data produced not only by nuclear techniques themselves, but also by other non-nuclear methods of analysis. The aim of this symposium was to provide an international forum for discussion of these topics. Its programme covered a wide variety of applications of nuclear (and related) analytical techniques (mainly neutron activation analysis, energy dispersive X ray fluorescence, particle induced X ray emission and inductively coupled plasma-mass spectrometry) as used in the study of air particulates, solid waste products, sediments, food, water, human tissues, biomonitors and other kinds of environmental samples

    In ecology and evolution, the primary challenge in understanding the processes that shape biodiversity is to assess the relationship between the phenotypic traits of organisms and the environment. Here we tested for selection on physio-morphological traits measured by scanning flow-cytometry at the individual level in phytoplankton communities under a temporally changing biotic and abiotic environment. Our aim was to study how high-frequency temporal changes in the environment influence biodiversity dynamics in a natural community. We focused on a spring bloom in Lake Zurich (Switzerland), characterized by rapid changes in phytoplankton, water conditions, nutrients and grazing (mainly mediated by herbivore ciliates). We described bloom dynamics in terms of taxonomic and trait-based diversity and found that diversity dynamics of trait-based groups were more pronounced than those of identified phytoplankton taxa. We characterized the linkage between measured phytoplankton traits, abiotic environmental factors and abundance of the main grazers and observed weak but significant correlations between changing abiotic and biotic conditions and measured size-related and fluorescence-related traits. We tested for deviations in observed community-wide distributions of focal traits from random patterns and found evidence for both clustering and even spacing of traits, occurring sporadically over the time series. Patterns were consistent with environmental filtering and phenotypic divergence under herbivore pressure, respectively. Size-related traits showed significant even spacing during the peak of herbivore abundance, suggesting that morphology-related traits were under selection from grazing. Pigment distribution within cells and colonies appeared instead to be associated with acclimation to temperature and water chemistry. We found support for trade-offs among grazing resistance and environmental tolerance traits, as well as for substantial periods of dynamics in which

    During the fall 2012 semester, students in two introductory courses at Susquehanna University - EENV:101 Environmental Science and POLI:131 World Affairs - will participate together in an online international relations simulation called Statecraft (www.statecraftsim.com). In this strategy game, students are divided into teams representing independent countries, and choose their government type (democracy, constitutional monarchy, communist totalitarian, or military dictatorship) and two country attributes (industrial, green, militaristic, pacifist, or scientific), which determine a set of rules by which that country must abide. Countries interact over issues such as resource distribution, war, pollution, immigration, and global climate change, and must also keep domestic political unrest to a minimum in order to succeed in the game. This simulation has typically been run in political science courses, as the goal is to allow students to experience the balancing act necessary to maintain control of global and domestic issues in a dynamic, diverse world. This semester, environmental science students will be integrated into the simulation, both as environmental advisers to each country and as independent actors representing groups such as Greenpeace, ExxonMobil, and UNEP. The goal in integrating the two courses in the simulation is for the students in each course to gain both 1) content knowledge of certain fundamental material in the other course, and 2) a more thorough, applied understanding of the integrated nature of the two subjects. Students will gain an appreciation for the multiple tradeoffs that decision-makers must face in the real world (economy, resources, pollution, health, defense, etc.). Environmental science students will link these concepts to the traditional course material through a "systems thinking" approach to sustainability. Political science students will face the challenges of global climate change and gain an understanding of the nature of

    The overall program objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is one or more environmental benign, a.k.a. ''green'' products that can be applied to maintain the structure and dependability of the natural gas infrastructure. Capsicum sp. extracts and pure compounds were screened for their antimicrobial activity against MIC causing bacteria. Studies on the ability of these compounds to dissociate biofilm from the substratum were conducted using microtiter plate assays. Tests using laboratory scale pipeline simulators continued. Preliminary results showed that the natural extracts possess strong antimicrobial activity being comparable to or even better than the pure compounds tested against strains of sulfate reducers. Their minimum inhibitory concentrations had been determined. It was also found that they possess bactericidal properties at minimal concentrations. Biofilm dissociation activity as assessed by microtiter plate assays demonstrated varying degrees of differences between the treated and untreated group with the superior performance of the extracts over pure compounds. Such is an indication of the possible benefits that could be obtained from these natural products. Confirmatory experiments are underway.

    The overall program objective is to develop and evaluate environmentally benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. Previous testing indicated that the growth, and the metal corrosion caused by pure cultures of sulfate reducing bacteria were inhibited by hexane extracts of some pepper plants. This quarter tests were performed with mixed bacterial cultures obtained from natural gas pipelines. Treatment with the pepper extracts affected the growth and metabolic activity of the microbial consortia. Specifically, the growth and metabolism of sulfate reducing bacteria was inhibited. The demonstration that pepper extracts can inhibit the growth and metabolism of sulfate reducing bacteria in mixed cultures is a significant observation validating a key hypothesis of the project. Future tests to determine the effects of pepper extracts on mature/established biofilms will be performed next.

The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. Previous testing of pepper extracts resulted in preliminary data indicating that some pepper extracts inhibit the growth of some corrosion-associated microorganisms. This quarter additional tests were performed to more specifically investigate the ability of three pepper extracts to inhibit the growth, and to influence the metal corrosion caused by two microbial species: Desulfovibrio vulgaris, and Comomonas denitrificans. All three pepper extracts rapidly killed Desulfovibrio vulgaris, but did not appear to inhibit Comomonas denitrificans. While corrosion rates were at control levels in experiments with Desulfovibrio vulgaris that received pepper extract, corrosion rates were increased in the presence of Comomonas denitrificans plus pepper extract. Further testing with a wider range of pure bacterial cultures, and more importantly, with mixed bacterial cultures should be performed to determine the potential effectiveness of pepper extracts to inhibit MIC.

Previous testing indicated that the growth, and the metal corrosion caused by pure cultures of sulfate reducing bacteria were inhibited by hexane extracts of some pepper plants. This quarter tests were performed to determine if chemical compounds other than pepper extracts could inhibit the growth of corrosion-associated microbes and to determine if pepper extracts and other compounds can inhibit corrosion when mature biofilms are present. Several chemical compounds were shown to be capable of inhibiting the growth of corrosion-associated microorganisms, and all of these compounds limited the amount of corrosion caused by mature biofilms to a similar extent. It is difficult to control corrosion caused by mature biofilms, but any compound that disrupts the metabolism of any of the major microbial groups present in corrosion-associated biofilms shows promise in limiting the amount/rate of corrosion.

    The overall program objective is to develop and evaluate environmentally benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. Various chemicals that inhibit the growth and/or the metabolism of corrosion-associated microbes such as sulfate reducing bacteria, denitrifying bacteria, and methanogenic bacteria were evaluated to determine their ability to inhibit corrosion in experiments utilizing pure and mixed bacterial cultures, and planktonic cultures as well as mature biofilms. Planktonic cultures are easier to inhibit than mature biofilms but several compounds were shown to be effective in decreasing the amount of metal corrosion. Of the compounds tested hexane extracts of Capsicum pepper plants and molybdate were the most effective inhibitors of sulfate reducing bacteria, bismuth nitrate was the most effective inhibitor of nitrate reducing bacteria, and 4-((pyridine-2-yl)methylamino)benzoic acid (PMBA) was the most effective inhibitor of methanogenic bacteria. All of these compounds were demonstrated to minimize corrosion due to MIC, at least in some circumstances. The results obtained in this project are consistent with the hypothesis that any compound that disrupts the metabolism of any of the major microbial groups present in corrosion-associated biofilms shows promise in limiting the amount/rate of corrosion. This approach of controlling MIC by controlling the metabolism of biofilms is more environmentally benign than the current approach involving the use of potent biocides, and warrants further investigation.

    Full Text Available This paper compares and contrasts a number of international approaches to the hydraulic control of surface water runoff from new development and redevelopment, known as sustainable drainage systems (SuDS or low impact development (LID. The paper provides a commentary on the progress and current status of national standards for SuDS in the UK to control the frequency, flow rate and volume of runoff from both frequent and extreme rainfall events, and the best practice design criteria presented in the revised UK CIRIA SuDS Manual, published in November 2015. The paper then compares these design criteria and standards with those developed and applied in China, USA, France and Germany and also looks at the drivers behind their development. The benefits of these different approaches are assessed in the context of flood risk mitigation, climate resilience and wider environmental protection objectives, including water quality, morphology and ecology. The paper also reviews the design approaches promoted by the new SuDS Manual and internationally for delivering additional benefits for urban spaces (such as recreation, visual character, education and economic growth through multi-functional urban design.

    The International Classification of High-resolution Computed Tomography (HRCT) for Occupational and Environmental Respiratory Diseases (ICOERD) has been developed for the screening, diagnosis, and epidemiological reporting of respiratory diseases caused by occupational hazards. This study aimed to establish a correlation between readings of HRCT (according to the ICOERD) and those of chest radiography (CXR) pneumoconiotic parenchymal opacities (according to the International Labor Organization Classification/International Classification of Radiographs of Pneumoconioses [ILO/ICRP]). Forty-six patients with and 28 controls without mineral dust exposure underwent posterior-anterior CXR and HRCT. We recorded all subjects' exposure and smoking history. Experts independently read CXRs (using ILO/ICRP). Experts independently assessed HRCT using the ICOERD parenchymal abnormalities grades for well-defined rounded opacities (RO), linear and/or irregular opacities (IR), and emphysema (EM). The correlation between the ICOERD summed grades and ILO/ICRP profusions was evaluated using Spearman's rank-order correlation. Twenty-three patients had small opacities on CXR. HRCT showed that 21 patients had RO; 20 patients, IR opacities; and 23 patients, EM. The correlation between ILO/ICRP profusions and the ICOERD grades was 0.844 for rounded opacities (p<0.01). ICOERD readings from HRCT scans correlated well with previously validated ILO/ICRP criteria. The ICOERD adequately detects pneumoconiotic micronodules and can be used for the interpretation of pneumoconiosis.

    Hospital-associated infections cause considerable morbidity and mortality, and are expensive to treat. Organisms causing these infections can be sourced from the inanimate environment around a patient. Could the difficulty in eradicating these organisms from the environment be because they reside in dry surface biofilms? The intensive care unit (ICU) of a tertiary referral hospital was decommissioned and the opportunity to destructively sample clinical surfaces was taken in order to investigate whether multidrug-resistant organisms (MDROs) had survived the decommissioning process and whether they were present in biofilms. The ICU had two 'terminal cleans' with 500 ppm free chlorine solution; items from bedding, surrounds, and furnishings were then sampled with cutting implements. Sections were sonicated in tryptone soya broth and inoculated on to chromogenic plates to demonstrate MDROs, which were confirmed with the Vitek2 system. Genomic DNA was extracted directly from ICU samples, and subjected to polymerase chain reaction (PCR) for femA to detect Staphylococcus aureus and the microbiome by bacterial tag-encoded FLX amplicon pyrosequencing. Confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM) were performed on environmental samples. Multidrug-resistant bacteria were cultured from 52% (23/44) of samples cultured. S. aureus PCR was positive in 50%. Biofilm was demonstrated in 93% (41/44) of samples by CLSM and/or SEM. Pyrosequencing demonstrated that the biofilms were polymicrobial and contained species that had multidrug-resistant strains. Dry surface biofilms containing MDROs are found on ICU surfaces despite terminal cleaning with chlorine solution. How these arise and how they might be removed requires further study.

  11. Organizational choices for international cooperation: East-West European cooperation on regional environmental problems

    Science.gov (United States)

    Connolly, Barbara Mary

    This dissertation applies theoretical insights from transaction cost economics to explain and predict the organizational form of cooperative agreements between Eastern and Western Europe in areas of regional environmental and political concern. It examines five contracting problems related to nuclear power safety and acid rain, and describes the history of international negotiations to manage these problems. It argues that the level of interdependence in a given issue area, or costly effects experienced in one state due to activities and decisions of other states, along with the level of transactional vulnerability, or sunk costs invested in support of a particular contractual relationship among these states, are key determinants of the governance structures states choose to facilitate cooperation in that issue area. Empirically, the dissertation traces the evolution of three sets of institutional arrangements related to nuclear safety: governance for western nuclear safety assistance to Eastern Europe, negotiations of a global convention on safety standards for nuclear power plants, and contracts among utilities and multilateral banks to build new nuclear power plants in Eastern Europe. Next it studies European acid rain, chronicling the history of international acid rain controls within the UNECE Convention on Long-Range Transboundary Air Pollution (LRTAP) and the European Union, and finally examining institutional arrangements for burden-sharing to promote European bargains on emissions reduction, including bilateral aid transfers and proposals for multilateral burden sharing. Political actors have a wide range of choice among institutional arrangements to facilitate international cooperation, from simple market-type exchanges, to arbitration-type regimes that provide information and enhance reputation effects, to self-enforcing agreements such as issue-linkage, to supranational governance. The governance structures states devise to manage their cooperative

    Full Text Available Second generation area-based indices of multiple deprivation have been extensively used in the UK over the last 15 years. They resulted from significant developments in political, technical, and conceptual spheres for deprivation data. We review the parallel development of environmental justice research and how and when environmental data was incorporated into these indices. We explain the transfer of these methods from the UK to Germany and assess the progress internationally in developing such indices.

    Ward closure is a method of controlling hospital-acquired infectious diseases outbreaks and is often coupled with other practices. However, the value and efficacy of ward closures remains uncertain. To understand the current practices and perceptions with respect to ward closure for hospital-acquired infectious disease outbreaks in acute care hospital settings across Canada. A Web-based environmental scan survey was developed by a team of infection prevention and control (IPC) experts and distributed to 235 IPC professionals at acute care sites across Canada. Data were analyzed using a mixed-methods approach of descriptive statistics and thematic analysis. A total of 110 completed responses showed that 70% of sites reported at least 1 outbreak during 2013, 44% of these sites reported the use of ward closure. Ward closure was considered an "appropriate," "sometimes appropriate," or "not appropriate" strategy to control outbreaks by 50%, 45%, and 5% of participants, respectively. System capacity issues and overall risk assessment were main factors influencing the decision to close hospital wards following an outbreak. Results suggest the use of ward closure for containment of hospital-acquired infectious disease outbreaks in Canadian acute care health settings is mixed, with outbreak control methods varying. The successful implementation of ward closure was dependent on overall support for the IPC team within hospital administration.

    In this study, we applied Environmental Scanning Electron Microscopy-Energy Dispersive Spectroscopy (ESEM-EDS) and Atomic Force Microscopy (AFM) analysis to three different cereal caryopses: barley, oat and einkorn wheat. The morphological structures, chemical elemental composition and surface characteristics of the three cereals were described. Regarding the morphology, barley showed the thickest pericarp, providing a strong barrier digestion and absorption of nutrients. The aleurone layer of each cereal type contained protein body globoids within its cells. Large type-A and small type-B starchy granules were revealed in the endosperm of barley and einkorn wheat, whereas irregular starchy granules were found in oats. The starchy granule elemental composition, detected by ESEM-EDS, was rather homogenous in the three cereals, whereas the pericarp and protein body globoids showed heterogeneity. In the protein body globoids, oats showed higher P and K concentrations than barley and einkorn wheat. Regarding the topographic profiles, detected by AFM, einkorn wheat starchy granules showed a surface profile that differed significantly from that of oats and barley, which were quite similar to one another. The present work provides insights into the morphological and chemical makeup of the three grains shedding light on the higher bio-accessibility of einkorn wheat nutrients compared to barley and oats, providing important suggestions for human nutrition and technological standpoints.

    Ferromanganese crusts record long-term deep-sea environmental changes. Thus, providing their reliable high-resolution age models is important. We applied a magnetostratigraphic technique to estimate the growth rate of a ferromanganese crust using scanning SQUID (superconducting quantum interference device) microscope (SSM). SSM is designed to map the magnetic field across thin sections with submillimeter resolution. The crust sample was taken from the Takuyo-Daigo Seamount, northwestern Pacific, and recorded a limited supply of dust and sediment from continents. After drift correction and removal of spike noises, the magnetic field values were stacked within the areas of high signal-to-noise ratios. By correlating the obtained profiles with a standard geomagnetic polarity timescale, we obtained an average growth rate of 3.37 ± 0.06 mm/Ma, which is consistent with that obtained by 10Be/9Be geochronology (2.93 ± 0.15 mm/Ma). S ratio mapping shows low values after 3 Ma, associated with voids between columnar structures.

So, essentially preventive severe conditions such as mandatory use of protective devices and soundproof acoustic shortening service personnel are needed for these people.

  19. Radionuclide scanning

    Shapiro, B.

    1986-01-01

    Radionuclide scanning is the production of images of normal and diseased tissues and organs by means of the gamma-ray emissions from radiopharmaceutical agents having specific distributions in the body. The gamma rays are detected at the body surface by a variety of instruments that convert the invisible rays into visible patterns representing the distribution of the radionuclide in the body. The patterns, or images, obtained can be interpreted to provide or to aid diagnoses, to follow the course of disease, and to monitor the management of various illnesses. Scanning is a sensitive technique, but its specificity may be low when interpreted alone. To be used most successfully, radionuclide scanning must be interpreted in conjunction with other techniques, such as bone radiographs with bone scans, chest radiographs with lung scans, and ultrasonic studies with thyroid scans. Interpretation is also enhanced by providing pertinent clinical information because the distribution of radiopharmaceutical agents can be altered by drugs and by various procedures besides physiologic and pathologic conditions. Discussion of the patient with the radionuclide scanning specialist prior to the study and review of the results with that specialist after the study are beneficial

    The scholars comprising journal editorial boards play a critical role in defining the trajectory of knowledge in their field. Nevertheless, studies of editorial board composition remain rare, especially those focusing on journals publishing research in the increasingly globalized fields of science, technology, engineering, and math (STEM). Using metrics for quantifying the diversity of ecological communities, we quantified international representation on the 1985-2014 editorial boards of 24 environmental biology journals. Over the course of 3 decades, there were 3,827 unique scientists based in 70 countries who served as editors. The size of the editorial community increased over time-the number of editors serving in 2014 was 4-fold greater than in 1985-as did the number of countries in which editors were based. Nevertheless, editors based outside the "Global North" (the group of economically developed countries with high per capita gross domestic product [GDP] that collectively concentrate most global wealth) were extremely rare. Furthermore, 67.18% of all editors were based in either the United States or the United Kingdom. Consequently, geographic diversity-already low in 1985-remained unchanged through 2014. We argue that this limited geographic diversity can detrimentally affect the creativity of scholarship published in journals, the progress and direction of research, the composition of the STEM workforce, and the development of science in Latin America, Africa, the Middle East, and much of Asia (i.e., the "Global South").

    Measurements have been carried out on the concentration of low levels of long-lived isotopes of 239+240 Pu and 90 Sr in the environmental materials such as atmospheric particulates, drinking water and food. The estimation of daily intake of these isotopes through inhalation and ingestion is a pre-requisite for the assessment of internal exposure. This paper presents temporal distribution of 239+240 Pu and 90 Sr in rain water, drinking water and total diet samples collected at Trombay site. The annual committed effective dose due to 90 Sr through inhalation and diet to the population of Bombay has been estimated to be 0.06 nSv/y and 0.48 μSv/y, respectively, and the same for 239+240 Pu is 1.3 nSv/y and 0.9 nSv/y, respectively. The data is discussed in relation to previous years' values to assess for any significant increase. (author). 9 refs., 3 figs., 2 tabs

  6. Power and knowledge in international environmental politics: The case of stratospheric ozone depletion

    1992-01-01

    Most analyses of science in world politics suffer from the modern misreading of the relationship between knowledge and power. The availability of scientific knowledge to the relevant decision makers was a necessary condition for the negotiation of the Montreal Protocol on Substances that Deplete the Ozone Layer, but it was far from being a sufficient one. The power of science was a function of the political context in which it was debated, a context which was defined substantially by the discovery of the Antarctic ozone 'hole.' The prominence of knowledge-based power in at least some situations means that conventional materialist notions of power should be expanded to include a more discursive and productive conception of power. Environmental problems are not merely physical events, but informational phenomena. A case study methodology is used to develop an interactive conception of power and knowledge. A detailed study of the Montreal Protocol is offered, as well as less detailed studies of the international policy processes for acid rain and global climate change

    Full Text Available Wetland ecosystems have many economic and ecological functions and values, but today their security and existence have been heavily influenced by various natural and human factors. Therefore, the present study was conducted to identify, rank and assess environmental risks threatening Khur-e- Azini International wetland located in Hormozgan province. In order to identify risk factors, the Delphi method and the multi-criteria decision-making methods, AHP and TOPSIS were used for prioritizing risks. According to the results of the technique AHP, fuel smuggling, marine transportation and oil pollution were respectively ranked first to third. The results of TOPSIS technique based on the relative proximity (Cj + indicate that the oil pollution (1 and the fuel smuggling (0.9154 are ranked first to second. In general, based on the ranking of risks, 8.6 percent of risks were placed in the unbearable category, 8.6 percent of risks were placed in the significant category, 26.08 percent of risks were placed in the average category, and 30.43 percent of risks were placed in the category of tolerable risks. According to the results, management priorities and planning should be considered seriously to minimize the risks and consequences that have irreversible effects on the environment and wetlands function.

  8. Identifying and categorizing cobenefits in state-supported Australian indigenous environmental management programs: international research implications

    Full Text Available Significant natural resource management investment is flowing to bioculturally diverse areas occupied by indigenous and other socioeconomically and politically marginalized groups. Such investment focuses on environmental benefit but may also generate ancillary economic, social, and other cobenefits. Increased investor interest in such cobenefits is driving the emerging research literature on cobenefit identification, categorization, and assessment. For local people undertaking community-based natural resource management, this emerging cobenefit discourse creates opportunities for more holistic program assessments that better reflect local perspectives, but it also contains risks of increased reporting burdens and institutional capture. Here, we synthesize and critically review the cobenefit literature arising from Australian indigenous cultural and natural resource management programs, a context in which there is a strong investor interest in cobenefits, particularly from government. We identify a wide suite of cobenefits in the existing literature and highlight previously unrecognized conceptual gaps and elisions in cobenefit categorization, including inconsistencies in category definition, the underanalysis of key categories, and a lack of systematic attention to beneficiaries as well as benefits. We propose a clarified and expanded conceptual framework to identify consistently the full suite of benefits, thereby enabling further assessment, valuation, and development of incentive mechanisms, standards, and guidelines. Our analysis has implications for community-based natural resource management assessment in a wide range of international contexts.

    This study seeks to contribute to the recent literature by empirically investigating the causal effect of urban population growth and international trade on environmental pollution of China, for the period 1980-2014. The Johansen cointegration confirmed a long-run cointegration association among the utilised variables for the case of China. The direction of causality among the variables was, consequently, investigated using the recent bootstrapped Granger causality test. This bootstrapped Granger causality approach is preferred as it provides robust and accurate critical values for statistical inferences. The findings from the causality analysis revealed the existence of a bi-directional causality between import and urban population. The three most paramount variables that explain the environmental pollution in China, according to the impulse response function, are imports, urbanisation and energy consumption. Our study further established the presence of an N-shaped environmental Kuznets curve relationship between economic growth and environmental pollution of China. Hence, our study recommends that China should adhere to stricter environmental regulations in international trade, as well as enforce policies that promote energy efficiency in the urban residential and commercial sector, in the quest to mitigate environmental pollution issues as the economy advances.

    Full Text Available Introduction: While planning radiation therapy (RT for a carcinoma of the urinary bladder (CaUB, the intra-fractional variation of the urinary bladder (UB volume due to filling-up needs to be accounted for. This internal target volume (ITV is obtained by adding internal margins (IM to the contoured bladder. This study was planned to propose a method of acquiring individualized ITVs for each patient and to verify their reproducibility. Methods: One patient with CaUB underwent simulation with the proposed ‘bladder protocol’. After immobilization, a planning CT scan on empty bladder was done. He was then given 300 ml of water to drink and the time (T was noted. Planning CT scans were performed after 20 min (T+20, 30 min (T+30 and 40 min (T+40. The CT scan at T+20 was co-registered with the T+30 and T+40 scans. The bladder volumes at 20, 30 and 40 min were then contoured as CTV20, CTV30 and CTV40 to obtain an individualized ITV for our patient. For daily treatment, he was instructed to drink water as above, and the time was noted; treatment was started after 20 min. Daily pre- and post-treatment cone beam CT (CBCT scans were done. The bladder visualized on the pre-treatment CBCT scan was compared with CTV20 and on the post-treatment CBCT scan with CTV30. Results: In total, there were 65 CBCT scans (36 pre- and 29 post-treatment. Individualized ITVs were found to be reproducible in 93.85% of all instances and fell outside in 4 instances. Conclusions: The proposed bladder protocol can yield a reproducible estimation of the ITV during treatment; this can obviate the need for taking standard IMs.

    To study the three-dimensional movement of internal tumor bed fiducial and breast skin markers, using 320-multislice computed tomography (CT); and to analyze intrafractional errors for breast cancer patients undergoing breast irradiation. This study examined 280 markers on the skin of the breast (200 markers) and on the primary tumor bed (80 markers) of 20 patients treated by external-beam photon radiotherapy. Motion assessment was analyzed in 41 respiratory phases during 20 s of cine CT in the radiotherapy position. To assess intrafractional errors resulting from respiratory motion, four-dimensional CT scans were acquired for 20 patients. Motion in the anterior-posterior (A/P) and superior-inferior (S/I) directions showed a strong correlation (|r| > 0.7) with the respiratory curve for most markers (79% and 70%, respectively). The average marker displacements between maximum and minimum value during 20 s for the 200 breast skin metal markers were 1.1 ± 0.3 mm, 2.1 ± 0.6 mm, and 1.6 ± 0.4 mm in the left-right, A/P, and S/I directions, respectively. For the 80 tumor bed clips, displacements were 0.9 ± 0.2 mm in left-right, 1.7 ± 0.5 mm in A/P, and 1.1 ± 0.3 mm in S/I. There was no significant difference in the motion between breast quadrant regions or between the primary site and the other regions. Motion in primary breast tumors was evaluated with 320-multislice CT. Very little change was detected during individual radiation treatment fractions. Copyright © 2012 Elsevier Inc.

    This study aimed to identify screening tools, technologies and strategies that vision and hearing care specialists recommend to front-line healthcare professionals for the screening of older adults in long-term care homes who have dementia. An environmental scan of healthcare professionals took place via telephone interviews between December 2015 and March 2016. All interviews were audio recorded, transcribed, proofed for accuracy, and their contents thematically analysed by two members of the research team. A convenience sample of 11 professionals from across Canada specialising in the fields of vision and hearing healthcare and technology for older adults with cognitive impairment were included in the study. As part of a larger mixed-methods project, this qualitative study used semistructured interviews and their subsequent content analysis. Following a two-step content analysis of interview data, coded citations were grouped into three main categories: (1) barriers, (2) facilitators and (3) tools and strategies that do or do not work for sensory screening of older adults with dementia. We report on the information offered by participants within each of these themes, along with a summary of tools and strategies that work for screening older adults with dementia. Recommendations from sensory specialists to nurses working in long-term care included the need for improved interprofessional communication and collaboration, as well as flexibility, additional time and strategic use of clinical intuition and ingenuity. These suggestions at times contradicted the realities of service provision or the need for standardised and validated measures. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The present study served to gain further insight into the bactericidal effects of ellagitannins from Acalypha wilkesiana var. macafeana hort. against pathogenic bacteria. Ellagitannins from the aerial parts of A. wilkesiana var. macafeana hort. (EAW) inhibited the growth of Bacillus cereus (ATCC 11778), Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 11632) and Methicillin-resistant Staphylococcus aureus (MRSA) clinical strain with inhibition zones equal to 11.01 ± 1.53 mm, 16.63 ± 0.11 mm, 11.40 ± 1.10 mm and 8.22 ± 0.19 mm, respectively. The minimal inhibition concentration and the minimal bactericidal concentration of ellagitannins from A. wilkesiana var. macafeana hort. (EAW) against MRSA were 750 µg/mL and 3000 µg/mL, respectively. We then examined the synergistic effect of EAW with three antibiotics, i.e. ampicillin, streptomycin and tetracycline, via the checkerboard assay and time-kill assay and observed that EAW is synergistic with ampicillin against S. aureus (ATCC 11632). Environmental electron scanning microscopy analysis showed cell lysis against S. aureus (ATCC 11632) upon treatment with the ellagitannin fraction. The ellagitannin fraction from A. wilkesiana var. macafeana hort. is bactericidal against gram-positive bacteria tested and works synergistically with ampicillin against S. aureus. Morphology analysis of the cell suggests that the bactericidal property of the ellagitannin fraction mechanism involves lysis of the cell wall. In summary, our studies demonstrate that A. wilkesiana var. macafeana hort. produces bactericidal ellagitannins of clinical and/or cosmetological value. Copyright © 2012 John Wiley & Sons, Ltd.

    This presentation will review the evolution of the workshops from a scientific and personal perspective. From their modest beginning in 1983, the workshops have developed into larger international meetings, regularly held every two years. Their initial focus on the aquatic sphere soon expanded to include properties and effects on atmospheric and terrestrial species, including man. Concurrent with this broadening of their scientific scope, the workshops have become an important forum for the early dissemination of all aspects of qualitative and quantitative structure-activity research in ecotoxicology and human health effects. Over the last few decades, the field of quantitative structure/activity relationships (QSARs) has quickly emerged as a major scientific method in understanding the properties and effects of chemicals on the environment and human health. From substances that only affect cell membranes to those that bind strongly to a specific enzyme, QSARs provides insight into the biological effects and chemical and physical properties of substances. QSARs are useful for delineating the quantitative changes in biological effects resulting from minor but systematic variations of the structure of a compound with a specific mode of action. In addition, more holistic approaches are being devised that result in our ability to predict the effects of structurally unrelated compounds with (potentially) different modes of action. Research in QSAR environmental toxicology has led to many improvements in the manufacturing, use, and disposal of chemicals. Furthermore, it has led to national policies and international agreements, from use restrictions or outright bans of compounds, such as polychlorinated biphenyls (PCBs), mirex, and highly chlorinated pesticides (e.g. DDT, dieldrin) for the protection of avian predators, to alternatives for ozone-depleting compounds, to better waste treatment systems, to more powerful and specific acting drugs. Most of the recent advances

    The co-organisers of the International Symposium on Health and Environmental Criteria and Standards for Radioactive Waste Disposal are pleased to present these proceedings. This Symposium succeeded in bringing together a wide range of participants and perspectives in order to address in a common forum the technical and non-technical issues related to long-term storage of radioactive waste. The papers presented herein reflect both the diversity of the participants and the complexity of the issues addressed. The sessions, panels, and papers developed for the symposium focused on some of the daunting challenges posed by long-term isolation and storage of high level radioactive waste. Panel sessions addressed the basic principles of criteria and standards, the context of the risks involved, and an overview of relevant philosophical, social, and ethical issues. Paper sessions considered national laws, policies and experiences; criteria formulation; environmental protection; compliance; human intrusion; and fundamental philosophical, social, and ethical issues. The presentations stimulated lively discussion and debate, and the contributors received valuable feedback. The interplay between technical and social aspects reflected in some papers and in the discussion highlights the changing role of the public in radioactive waste issues. The average citizen has become more aware of and more involved in radioactive waste matters in recent years. Solutions that were previously analysed through a technological lens are now being viewed in a much broader perspective that better addresses the concerns of local communities as well as national and international interests. Public involvement must begin earlier, last longer, and improve in quality so as to create an ongoing dialogue and debate rather than cycles of dictates and discord. The symposium has offered suggestions as to how government, industry, and the public can foster a broader dialogue on the formulation and

    Promoting young researchers is a major priority of the German Helmholtz Association. Since more than five years graduate and postgraduate education in the field of Earth System and Environmental Science has been established in Bremen and Bremerhaven, north-western Germany. Using the network and collaboration of experts and specialists on observational and paleoclimate data as well as on statistical data analysis and climate modelling from two Universities and the Helmholtz research institute on Polar and Marine Research, master and PhD students are trained to understand, decipher and cope with the challenges of recent climate change on an highly interdisciplinary and inter-institutional level. The existing research infrastructure at the Alfred Wegener Institute in Bremerhaven (AWI), University of Bremen, and Jacobs University Bremen offers a unique research environment to study past, present and future changes of the climate system, with special focus on high latitudinal processes. It covers all kind of disciplines, climate science, geosciences and biosciences, and provides a consistent framework for education and qualification of a new generation of expertly trained, internationally competitive master and PhD students. On postgraduate level, the Postgraduate Programme Environmental Physics (PEP) at the University of Bremen (www.pep.uni-bremen.de) educates the participants on the complex relationship between atmosphere, hydrosphere (ocean), cryosphere (ice region) and solid earth (land). Here, the learning of experimental methods in environmental physics at the most advanced level, numerical data analysis using supercomputers, and data interpretation via sophisticated methods prepare students for a scientific career. Within cooperation with the Ocean University of China (OUC) students are participating one year in the PEP programme during their master studies since 2006, to get finally a double degree of both universities.

    The Convention on the Protection of the Marine Environment of the Baltic Sea Area signed in 1974 in Helsinki is probably the most important environmental agreement consummated in the Baltic Sea region. This article is the first study that explores the history of this agreement, also known as the Helsinki Convention, by using primary archival sources. The principal sources are the archives of the Ministry for Foreign Affairs of Finland. We examine the role of Finland in the process that led to the signing of the Helsinki Convention from the perspective of international politics. The study focuses primarily on Finnish, Swedish, and Soviet state-level parties from the end of the 1960s to 1974. We show that Cold War politics affected in several ways negotiations and contents of the Helsinki Convention. We also argue that the Soviet Union used the emerging international environmental issues as a new tool of power politics.

    The globalization of agricultural trade has dramatically altered global nitrogen flows by changing the spatial pattern of nitrogen utilization and emissions at a global scale. As a major trading country, China uses a large amount of nitrogen, which has a profound impact on global nitrogen flows. Using data on food production and trade between China and 26 other countries and regions, we calculated nitrogen inputs and outputs in food production ecosystem in each country. We estimated nitrogen flows in international food trade and analyzed their impact on nitrogen pollution in China. We divided nitrogen flows into embodied and virtual nitrogen flows. Embodied nitrogen is taken up by the plant and incorporated into the final food product, whereas virtual nitrogen is lost to the environment throughout the food production process and is not contained in the final food product. Our results show that China mainly imports food products from America and Asia, accounting for 95 % of all imported food. Asia (mainly Japan) and Europe are the main exporters of food from China, with Japan and the EU accounting for 17 and 10 % of all exported food, respectively. Total nitrogen inputs and outputs in food production in China were 55,400 and 61,000 Gg respectively, which were much higher than in other countries. About 1440 and 950 Gg of embodied and virtual nitrogen respectively flow into China through the food trade, mainly from food-exporting countries such as the USA, Argentina, and Brazil. Meanwhile, 177 and 160 Gg of embodied and virtual nitrogen respectively flow out of China from the export of food products, mainly to Japan. China's net food imports have reduced 720 and 458 Gg for nitrogen utilization and outputs, respectively, which accounted for 1.3 and 0.78 % of total nitrogen inputs and outputs in China. These results suggest that food trade in China has a profound effect on nitrogen flows and has greatly reduced environmental impacts on nitrogen pollution in China.

  10. 3D Micro-topography of Transferred Laboratory and Natural Ice Crystal Surfaces Imaged by Cryo and Environmental Scanning Electron Microscopy

    Recent work has highlighted micro-scale roughness on the surfaces of ice crystals grown and imaged in-situ within the chambers of environmental scanning electron microscopes (ESEM). These observations appear to align with theoretical and satellite observations that suggest a prevalence of rough ice in cirrus clouds. However, the atmospheric application of the lab observations are indeterminate because the observations have been based only on crystals grown on substrates and in pure-water vapor environments. In this work, we present details and results from the development of a transfer technique which allows natural and lab-grown ice and snow crystals to be captured, preserved, and transferred into the ESEM for 3D imaging. Ice crystals were gathered from 1) natural snow, 2) a balloon-borne cirrus particle capture device, and 3) lab-grown ice crystals from a diffusion chamber. Ice crystals were captured in a pre-conditioned small-volume (~1 cm3) cryo-containment cell. The cell was then sealed closed and transferred to a specially-designed cryogenic dewer (filled with liquid nitrogen or crushed dry ice) for transport to a new Hitachi Field Emission, Variable Pressure SEM (SU-5000). The cryo-cell was then removed from the dewer and quickly placed onto the pre-conditioned cryo transfer stage attached to the ESEM (Quorum 3010T). Quantitative 3D topographical digital elevation models of ice surfaces are reported from SEM for the first time, including a variety of objective measures of statistical surface roughness. The surfaces of the transported crystals clearly exhibit signatures of mesoscopic roughening that are similar to examples of roughness seen in ESEM-grown crystals. For most transported crystals, the habits and crystal edges are more intricate that those observed for ice grown directly on substrates within the ESEM chamber. Portions of some crystals do appear smooth even at magnification greater than 1000x, a rare observation in our ESEM-grown crystals. The

    Natali, S.

    1984-01-01

    This chapter reports on the scanning of 1000 holograms taken in HOBC at CERN. Each hologram is triggered by an interaction in the chamber, the primary particles being pions at 340 GeV/c. The aim of the experiment is the study of charm production. The holograms, recorded on 50 mm film with the ''in line'' technique, can be analyzed by shining a parallel expanded laser beam through the film, obtaining immediately above it the real image of the chamber which can then be scanned and measured with a technique half way between emulsions and bubble chambers. The results indicate that holograms can be analyzed as quickly and reliably as in other visual techniques and that to them is open the same order of magnitude of large scale experiments

    Oftentimes, in managing podiatric complaints, clinical and conventional radiographic techniques are insufficient in determining a patient's problem. This is especially true in the early stages of bone infection. Bone scanning or imaging can provide additional information in the diagnosis of the disorder. However, bone scans are not specific and must be correlated with clinical, radiographic, and laboratory evaluation. In other words, bone scanning does not provide the diagnosis but is an important bit of information aiding in the process of diagnosis. The more useful radionuclides in skeletal imaging are technetium phosphate complexes and gallium citrate. These compounds are administered intravenously and are detected at specific time intervals postinjection by a rectilinear scanner with minification is used and the entire skeleton can be imaged from head to toe. Minification allows visualization of the entire skeleton in a single image. A gamma camera can concentrate on an isolated area. However, it requires multiple views to complete the whole skeletal image. Recent advances have allowed computer augmentation of the data received from radionucleotide imaging. The purpose of this chapter is to present the current radionuclides clinically useful in podiatric patients

    Never before has human kind been facing bigger environmental challenges than today. The challenges are overwhelming: growing human population, increasing ecological footprints, accelerated climate change, severe soil degradation, eutrophication of vital fresh water resources, acidification of oceans, health threatening air pollution and rapid biodiversity loss, to name just a few. It is the task of environmental scientists to transmit established knowledge on these complex and interdisciplinary challenges while demonstrating that management and engineering solutions exist to meet these threats. In this presentation I will outline the concept of my environmental impact (EI) assessment course, where prospective engineering students can select a topic of their choice, assess the environmental impacts, discuss with relevant stakeholders and come up with innovative solutions. The course is structured in three parts: i) lecturing of theoretical methods frequently used within the EI assessment process, ii) interaction with local businesses to acquire first-hand experience and iii) hands on training by writing an EI statement on a selected topic (see link below). Over the course of three years over 70 prospective engineering students from all over the world have not only acquired environmental system understanding, but also enhanced their awareness and developed potential solutions to mitigate, compensate and reverse the persistent environmental challenges. Most importantly, during this process all involved stakeholders (students, teachers, industry partners, governmental bodies and NGO partners) will hopefully develop a mutual understanding of the above mentioned environmental challenges and engage in an open and constructive dialogue necessary to generate acceptable solutions.

    This report describes the process and results from an effort to develop metrics for program accomplishments for the FY 1997 budget submission of the U.S. Department of Energy Environmental Management International Technology Integration Program (EM-ITI). The four-step process included interviews with key EM-ITI staff, the development of a strawman program logic chart, and all day facilitated workshop with EM-ITI staff during which preliminary performance plans and measures were developed and refined, and a series of follow-on discussions and activities including a cross-organizational project data base. The effort helped EM-ITI to crystallize and develop a unified vision of their future which they can effectively communicate to their own management and their internal and external customers. The effort sets the stage for responding to the Government Performance and Results Act. The metrics developed may be applicable to other international technology integration programs. Metrics were chosen in areas of eight general performance goals for 1997-1998: (1) number of forums provided for the exchange of information, (2) formal agreements signed, (3) new partners identified, (4) customers reached and satisfied, (5, 6) dollars leveraged by EM technology focus area and from foreign research, (7) number of foreign technologies identified for potential use in remediation of DOE sites, and (8) projects advanced through the pipeline

  2. A new international environmental order? An assessment of the impact of the global warming epistemic community

    Smith, H.A.

    1993-12-01

    Global warming is a problem which ignores national boundaries, making international cooperation essential. The role of epistemic communities, or those composed of professionals who share a commitment to a common causal model and a set of political values, in affecting the international response to the global warming problem is examined. It is claimed that the epistemic global warming community can affect the policy process, both domestically and internationally, and facilitate cooperation in an era of ecological interdependence. This claim is explored and eventually supported through the examination of two case studies: the responses of Canada and Britain to the issue of global warming between 1988 and November 1990. The case studies are supplemented with a more general discussion of the issues surrounding the international politics of global warming through the same period. Through these studies, it is found that a global warming community can be identified and that its efforts have played a significant role in framing the global warming issue. 121 refs

    1998-12-01

    This document examines the optimal environmental regulation of three Norwegian power projects, energy conservation, a natural gas fired combined cycle gas turbine and a new hydro project. All projects reduce emissions elsewhere in the Nordic region, and in general the environmental costs of these emissions are not optimally reflected in market prices. A theory of second best optimal regulation is developed for this case. The optimal regulation is found to deviate considerably from a purely domestic regulation. For instance, it is found optimal to grant a substantial credit to energy conservation. The credit is sensitive to the value of reduced CO{sub 2} emissions and whether the current Norwegian end user tax should be interpreted as an environmental or a fiscal tax. 27 refs., 4 tabs.

    The US Department of Energy (DOE) has collected, and will continue to collect, large amounts of information on its environmental waste sites and associated technology development efforts. This information is being gathered in a variety of formats for various purposes. Integration and delivery of this information WW benefit decision makers, waste site managers, technology developers, regulators, and the private sector. No computer system currently exists that acts as an easy-to-use computer umbrella over all of the DOE's environmental information. The EnviroTRADE Information System, currently under development for the DOE's Environmental Restoration and Waste Management's (EM's) Office of Technology Development, provides access to a wide variety of information within a single architecture. Ongoing system development is expected to result in an extensive, networked interface to EM's diverse data benefiting a variety of users. This paper discusses the present status of the EnviroTRADE Information System as well as current and future development activities

    Illegal trade in hazardous waste and harmful chemicals has caused severe damage on human health and the environment, and brought big challenges to countries to meet their commitments to related multilateral environmental agreements. Synergy-building, like organising law enforcement operations, is critical to address illegal trade in waste and chemicals, and further improve the effectiveness of environmental enforcement. This article discusses how and why law enforcement operations can help countries to implement chemical and waste-related multilateral environmental agreements in a more efficient and effective way. The research explores key barriers and factors for organising law enforcement operations, and recommends methods to improve law enforcement operations to address illegal trade in hazardous waste and harmful chemicals. © The Author(s) 2016.

    As a follow-up to our first paper in this journal, this paper discusses projects involving intensive and multiple use of space recently completed or still being developed around railway stations in London (Broadgate and Canary Wharf), Paris (Seine Rive Gauche and La Défense) and Amsterdam (Zuidas and Bijlmer). The cases were compared on the basis of spatial, functional and environmental indicators, as treated in our first paper. The environmental performance of each of the cases was determined through comparison with a theoretic reference project for an equal number of users, yet with average West-European urban values for spatial, functional and environmental properties. The case studies revealed that a high floor space index is easily achievable in urban plans, implying efficient use of land and preservation of green area outside the city. For a mono-functional office area it is easier to achieve a high FSI than for a functionally diverse area with, e.g. apartments and shops. Therefore, with respect to a reference functionally equal to the cases, the predominant office character of Canary Wharf, Broadgate and La Défense results in good environmental performance. However, on the basis of a functionally diverse reference, for which monofunctional cases were enlarged with additional area for housing and amenities, the varied areas of Zuidas and Seine Rive Gauche perform best. With respect to average urban plans, the cases achieved environmental improvement of factor 1.5. This performance is restricted by the energy consumption of buildings, which has by far the most influence on the end result.

    2005-01-01

    Full Text Available Introduction. This paper examines the business external environment scanning theory for information in the context of Greece. Method. A questionnaire was developed to explore the relationships between general and task business environment, perceived uncertainty, scanning strategy, and sources of information with respect to type of environment, size and industry.The research was based on a sample of 144 private organizations operating in North Greece. Analysis. Data collected were analysed using SPSS. The statistical procedures of chi-squared homogeneity test, ANOVA, Duncan's test of homogeneity of means, and related samples t-test were followed for testing the hypotheses developed. Results. The results show that perceived uncertainty of the general and task business external environment factors depend on the type of the environment, size of organization, and industry where the organizations operate; organizations adapt their scanning strategy to the complexity of the environment; personal sources of information seem to be more important than impersonal sources; external sources of information are equally important with internal sources; and higher levels of environmental uncertainty are associated with higher levels of scanning the various sources. Conclusion. Business external environment scanning of information is influenced by the characteristics of the organizations themselves and by the characteristics of the external environment within which the organizations operate. The study contributes to both environmental scanning theory and has important messages for practitioners.

  9. The significance of hair mineral analysis as a means for assessing internal body burdens of environmental pollutants

    International Nuclear Information System (INIS)

    1993-01-01

    In recent years there has been a considerable growth of interest in problems of environmental pollution from industrial and agricultural substances and the harmful impact of such pollution on human health. There has been an increasing interest in using hair mineral analysis for biological monitoring of human population exposure to environmental mineral pollutants. This is because hair has some ideal attributes for such purposes. It can be collected by simple, non-invasive methods, and is easily sampled and stored. Concentrations of most of the toxic trace elements, i.e. mercury and lead, in scalp hair are at least an order of magnitude higher than those in body fluids or other easily accessible tissues. In addition, mineral elements in hair can easily be determined with good precision and sensitivity by nuclear as well as conventional methods of chemical analysis. Despite these apparent advantages of using hair as a biomonitor, serious uncertainty existed, and to some extent still exist, as to the meaningful interpretation of human hair mineral data in environmental health studies. The Co-ordinated Research Programme (CRP), which is the subject of this report, has attempted to tackle this problem by promoting a variety of studies (as distinct from routine monitoring) to investigate the quantitative relationships between internal body burdens of a number of elements of environmental health significance and their respective concentrations in hair.

    It is hard to draw a boundary between those impacts on the environment which are specifically related to energy and those which are a general consequence of the concentration of human activities. This survey of international activities on energy and the environment will be restricted to those effects which commonly operate across international boundaries and will not include such problems as the airborne chemical problems at Bhopal, the Rhine spill at Basel or the ozone depletion by chlorofluorocarbons. The major international energy-related concerns are: (1) carbon dioxide and the possible warming of the earth; (2) sulfur oxides, nitrogen oxides and photochemical oxidant effects on lakes, streams, forests, and structures; (3) nuclear radioactive releases from weapons testing and power plants as they affect human health; and (4) the disposal of radioactive waste as a possible threat for the future ground water supplies or oceans

  3. Energy tax harmonization in the European Union: a proposal based on the internalization of environmental external costs

    International Nuclear Information System (INIS)

    Dorigoni, S.; Gulli, F.

    2002-01-01

    Energy tax harmonization is a crucial step towards the creation of a single market. In this article the possibility of achieving such an objective is discussed. The paper consists of two sections. In the first the European taxation on energy products is analysed. This analysis is useful in showing the differences that exist between the European countries that account for the difficulties met so far in the process of harmonization. In this respect we comment on the recent proposal of the Directive of the European Union, which lays down the obligation of minimum levels of taxation in all European member states. In the second section, after simulating the effects related to the adoption of a common environmental taxation (a first best solution based on the internalization of environmental external costs), we propose, as a second best solution, an excise tax harmonization model taking into consideration the specificity of each country and being, as far as possible, coherent with the environmental objective. This model proposes: the introduction of a minimum level of taxation on all products equal to the external cost due to the greenhouse effect (a common carbon tax); the possibility, given to the member states, of deviating from such minimum levels, in accordance with their specific requirements, internalizing in the price of the different products, by means of taxes additional to that CO 2 minimum, the external costs associated with other pollutant agents (the same in all countries); the opportunity, in case it should be necessary to exceed the entire external cost, for the member states to apply increases that are in accordance with the environmental objective.

    Aishlin, P. S.; Selker, J. S.

    Climate change understanding and impacts vary by community, yet the global nature of climate change requires international collaboration to address education, monitoring, adaptation and mitigation needs. We propose that effective climate change monitoring and education can be accomplished via student-led local and international community partnerships. By empowering students as community leaders in climate-environmental monitoring and education, as well as exploration of adaptation/mitigation needs, well-informed communities and young leadership are developed to support climate change science moving forward. Piloted 2013-2015, the SLICEIT1 program partnered with TAHMO2 to connect student leaders in North America, Europe and Africa. At the international level, schools in the U.S.A and Netherlands were partnered with schools in Ghana, Kenya, and Uganda for science and cultural exchange. Each school was equipped with a climate or other environmental sensing system, real-time data publication and curricula for both formal and informal science, technology, engineering and math education and skill development. African counterparts in TAHMO's School-2-School program collect critically important data for enhanced on-the-ground monitoring of weather conditions in data-scarce regions of Africa. In Idaho, student designed, constructed and installed weather stations provide real time data for classroom and community use. Student-designed formal educational activities are disseminated to project partners, increasing hands-on technology education and peer-based learning. At the local level, schools are partnered with a local agency, research institute, nonprofit organization, industry and/or community partner that supplies a climate science expert mentor to SLICEIT program leaders and teachers. Mentor engagement is facilitated and secured by program components that directly benefit the mentor's organization and local community via climate/environment monitoring, student workforce

  8. International classifications of accounting systems as a result of influence of various environmental factors

    2012-12-01

    Full Text Available Activities of various environmental factors resulted in the emergence of accounting clusters that in- clude equal or similar countries, observed through evaluation (measurement criteria and publishing, which has led to group formation, i.e. clusterisation of accounting systems within similar or equal groups, subgroups and clusters. The key principle of group formation of accounting systems within certain clusters implies similar accounting practices, primarily the practice of measuring (evaluating positions and publishing information in financial reports. The measurement level and the quantity of published information is related to the environmental factors, primarily to cultural heritage, which, according to claims of numerous authors, is of crucial importance. If accounting practices of the com- pared countries are observed according to this factor, then it is possible to form at least two or more clusters, which is significant in the world of financial reporting as there are some controversies in the relation between IASB and FASB even today.

  9. CISM-IUTAM International Summer School on Continuum Mechanics in Environmental Sciences and Geophysics

    CERN Document Server

    1993-01-01

    Modern continuum mechanics is the topic of this book. After its introduction it will be applied to a few typical systems arising in the environmental sciences and in geophysics. In large lake/ocean dynamics peculiar effects of the rotation of the Earth will be analyzed in linear/nonlinear processes of a homogenous and inhomogenous water body. Strong thermomechanical coupling paired with nonlinear rheology affects the flow of large ice sheets (such as Antarctica and Greenland) and ice shelves. Its response to the climatic forcing in an environmental of greenhouse warming may significantly affect the life of future generations. The mechanical behavior of granular materials under quasistatic loadings requires non-classical mixture concepts and encounters generally complicated elastic-plastic-type constitutive behavior. Creeping flow of soils, consolidation processes and ground water flow are described by such theories. Rapid shearing flow of granular materials lead to constitutive relations for the stresses whic...

  11. Acoustic mode coupling induced by shallow water nonlinear internal waves: sensitivity to environmental conditions and space-time scales of internal waves.

    Science.gov (United States)

    Colosi, John A

    2008-09-01

    While many results have been intuited from numerical simulation studies, the precise connections between shallow-water acoustic variability and the space-time scales of nonlinear internal waves (NLIWs) as well as the background environmental conditions have not been clearly established analytically. Two-dimensional coupled mode propagation through NLIWs is examined using a perturbation series solution in which each order n is associated with nth-order multiple scattering. Importantly, the perturbation solution gives resonance conditions that pick out specific NLIW scales that cause coupling, and seabed attenuation is demonstrated to broaden these resonances, fundamentally changing the coupling behavior at low frequency. Sound-speed inhomogeneities caused by internal solitary waves (ISWs) are primarily considered and the dependence of mode coupling on ISW amplitude, range width, depth structure, location relative to the source, and packet characteristics are delineated as a function of acoustic frequency. In addition, it is seen that significant energy transfer to modes with initially low or zero energy involves at least a second order scattering process. Under moderate scattering conditions, comparisons of first order, single scattering theoretical predictions to direct numerical simulation demonstrate the accuracy of the approach for acoustic frequencies upto 400 Hz and for single as well as multiple ISW wave packets.

    2000-01-01

    As the International Space Station's (ISS) various habitable modules are placed in service on orbit, the need to provide for sustaining engineering becomes increasingly important to ensure the proper function of critical onboard systems. Chief among these are the Environmental Control and Life Support System (ECLSS) and the Internal Thermal Control System (ITCS). Without either, life onboard the ISS would prove difficult or nearly impossible. For this reason, a ground-based ECLSS/ITCS hardware performance simulation capability has been developed at NASA's Marshall Space Flight Center. The ECLSS/ITCS Sustaining Engineering Test Bed will be used to assist the ISS Program in resolving hardware anomalies and performing periodic performance assessments. The ISS flight configuration being simulated by the test bed is described as well as ongoing activities related to its preparation for supporting ISS Mission 5A. Growth options for the test facility are presented whereby the current facility may be upgraded to enhance its capability for supporting future station operation well beyond Mission 5A. Test bed capabilities for demonstrating technology improvements of ECLSS hardware are also described.

Cross-sectional, observational cohort. Community. A sample of community-dwelling adults with stroke, spinal cord injury, and traumatic brain injury (N=568). None. EFIB covering domains of the built and natural environment; systems, services, and policies; social environment; and access to information and technology; the Craig Hospital Inventory of Environmental Factors (CHIEF) short form; the Facilitators and Barriers Survey/Mobility (FABS/M) short form; the Home and Community Environment Instrument (HACE); the Measure of the Quality of the Environment (MQE) short form; and 3 of the Patient Reported Outcomes Measurement Information System's (PROMIS) Quality of Social Support measures. The EFIB and legacy instruments assess most of the International Classification of Functioning, Disability and Health (ICF) environmental factors chapters, including chapter 1 (products and technology; 75 items corresponding to 11 codes), chapter 2 (natural environment and human-made changes; 31 items corresponding to 7 codes), chapter 3 (support and relationships; 74 items corresponding to 7 codes), chapter 4 (attitudes; 83 items corresponding to 8 codes), and chapter 5 (services, systems, and policies; 72 items corresponding to 16 codes). Construct validity is provided by moderate correlations between EFIB measures and the CHIEF, MQE barriers, HACE technology mobility, FABS/M community built features, and PROMIS item banks and by small correlations with other legacy instruments. Only 5 of the 66 legacy instrument correlation coefficients are moderate, suggesting they measure unique aspects of the environment, whereas all intra-EFIB correlations were at least moderate. The EFIB measures provide a brief and focused assessment of ICF

    The paper examines the following points in connection with claims for compensation and to protection against abridgement of legal rights involving foreign persons or legal entities: - The limits set by international law to national judicial authority, - the international competence of courts, i.e. under which conditions national courts can have jurisdiction in cases involving foreign persons or legal entities, - the applicable law, and finally the question of - under which conditions judgements of the judiciary state must be observed abroad and foreign judgements must be observed in the judiciary state, i.e. acknowledged and executed. In the case of impairments of the environment the particular problem arises of the effect of licences issued under public law. The paper discusses the former practice, the qualification, the ways of observing the legal rules governing licences and their effects, and the question as to the unconditional enforcement of national licences against foreign affected parties.

    Biomass plays a key role to achieve the EU's 20-20-20 energy and climate targets. Because of rising European demand and limited domestic resources, the EU relies on worldwide imports. Given this framework, the present thesis explores the influences on wood pellet supply chains considering different environmental policies, price risks and the effect of torrefaction pretreatment. The examinations refer to three real case studies for pellet trade from Australia, Canada, and Russia to Europe. In the first investigation, the efficiency of co-firing imported wood pellets in terms of CO{sub 2} savings and related subsidy schemes is analysed. Scenarios show that co-firing biomass is efficient to contribute to the EU energy targets. Though, policy makers could use these instruments more effective when directing sourcing decision towards options with even less environmental impacts. The second analysis explores the influence of statistically derived price risks on total supply chain economics. It is shown that price risks can effect strong fluctuations in the short term, which seriously affect the profitability of individual trade routes. Securing the supply chain is mainly based on individual producer-buyer agreements, personal branch experiences and fast reactions on the subsidy system. Systematic evaluation of supply chains could contribute to a more reliable market and thus foster investment decisions. In the last investigation, the economic and environmental performance of potential torrefaction-based supply chains is assessed. As a result, torrefaction-based supply chains turn out to be a certain alternative to conventional ones. Though, still huge research efforts and industrial demonstration are required to make torrefied biomass a real alternative on the market.

    The International Conference on Mathematics and Computations, Reactor Physics, and Environmental Analyses marks the sixteenth biennial topical meeting of the Mathematics and Computation (M ampersand C) Division of the American Nuclear Society (ANS). This conference combines many traditional features of M ampersand C conferences with several new aspects. The meeting is, for the first time, being held in Portland, Oregon and sponsored by the ANS Eastern Washington Section. Three of the cosponsors - the ANS Reactor Physics Division, the European Nuclear Society, and the Atomic Energy Society of Japan - have participated in a series of such meetings, with very successful results. The fourth cosponsor, the ANS Environmental Science Division, is participating for the first time as a cosponsor of a M ampersand C topical meeting, as a result of the M ampersand C Division's decision to formally include the area of environmental analyses as a major focus of the conference, another 'first.' Separate abstracts have been submitted to the energy database for contributions to this conference

    1995-09-01

    The Nordic EIA-effectiveness (Environmental Impact Assessment) workshop met in Tuusula, Finland 10-12 april 1994. EIA-experts from all Nordic countries and Canada discussed cases in which environmental impact assessment procedures had been applied with varying success. Nordic cases are included in the proceedings as separate chapters. The problems and successes of diverse cases allowed experts to identify key issues and avenues for future development. The reports of the working groups cover all stages of the EIA-process and provide reference material for future studies. `How can we ensure that EIA, which now has legal backing in all Nordic countries, becomes an efficient way to improve public participation and to avoid deleterious changes in the environment?` is the basic theme. Several recommendations were put forward for building on the results of the workshop, i.e. to: 1) elaborate and consolidate the criteria developed by the working groups and cross reference with the results of other international workshops; 2) review their application of EIA capacity building in countries with transitional economies; 3) test the proposed guidelines of good practice in EIAs in Nordic countries and disseminate the results; establish ecosystem specific approaches for sensitive and distinctive bioregions; and 5) focus on the Arctic as a priority area shared by eight northern countries and covered by a regional environmental strategy.

    Pesticides are an integral component of agricultural systems throughout the world. It is generally accepted that this will continue for the foreseeable future if production of food of acceptable quality is to increase. However, pesticide use has costs as well as benefits. Concerning the environment, information must be provided before a product is registered in order to provide assurance that it can be used without unacceptable hazard to non-target organisms. In addition, post-registration surveillance and monitoring studies are necessary to check that the fate and environmental effects of pesticides under field conditions are consistent with predictions. Much of the data are generated using radioisotopes and other nuclear or related methods that can be applied in studies related to the fate and effects of pesticides in the various environmental compartments (soil, water and air), and in terrestrial (agricultural and non-agricultural) and marine ecosystems. For a variety of reasons, developing countries often have to rely on data generated elsewhere in order to assess the acceptability of a compound, particularly if it is off-patent. This Symposium was organized to examine the circumstances under which extrapolation from one environment to another is valid on the basis of data generated under comparable conditions. It also considered ways in which relatively simple methods can be used to verify the field applicability of data obtained under sophisticated experimental conditions. Refs, figs, tabs

  3. Proceedings of the international symposium on post-Chernobyl environmental radioactivity studies in East European countries

    International Nuclear Information System (INIS)

    2004-01-01

    The Chernobyl accident on 26th April 1986 reminded the world that the threat coming from nuclear power-plants is not fictitious. The societies of the neighbouring countries suffered a real shock caused not only by the accident itself, but also by the fact that information was restricted and hardly available. Even now, our knowledge about the scale and consequences of the accident is limited. After the accident many international organizations and institutions dealing with environment protection and others started to investigate different aspects of this case. As a result of this interest, many symposia and conferences have been organized. The aim has been not only to estimate the consequences of this single case, to investigate the level of environment protection or to elaborate the new, better methods of environment monitoring. Also moral, legal and psychological aspects of the situation are being investigated. The territory of Poland, lying close to the accident place, suffered its direct influence. Thus, not only government and scientific institutions deal with the subject, but there is also a growing interest of the society, which demands more and more reliable information about the Chernobyl accident effects. Many Central- and East-European countries are in similar situation. Following general interest of Chernobyl accident effects, the Maria Curie-Sklodowska University in Lublin (Poland) and the Jozef Stefan Institute in Ljubljana (Yugoslavia) organized on 17-19th September 1990 in Kazimierz on the Vistula (Poland) a joint international conference having the character of workshop. The conference was organized on the basis of already existing scientific collaboration of these institutions with the co-operation of the European Community (Brussels, Belgium) and International Atomic Energy Agency (Vienna, Austria)

    Full Text Available ¿Como se resuelve el problema de la objetivación del vínculo de conexión cuando intervienen daños civiles y daños ambientales? Es decir, ¿podemos sostener que el fuero "lugar del hecho dañoso" puede determinarse con independencia de los sujetos que intervienen? ¿Es relevante el principio favor laesi en los casos de daño ambiental? Proponemos abordar estos problemas desde la relación que existe entre los principios de Competencia Judicial Civil Internacional y los principios de protección del medioambiente. Así, advertiremos que la mayor o menor extensión del fuero "lugar del hecho dañoso", adquiere connotaciones especiales si interpretamos armónicamente los principios de competencia judicial internacional y los principios de protección internacional del medio ambiente. En efecto, la política de protección ambiental, constituye un "valor superior del ordenamiento", y por tanto incide directamente en el juicio razonabilidad que el juez debe realizar sobre el vínculo de conexión. Si bien abordamos el problema desde la experiencia europea, las conclusiones tendrán validez universal.How to solve the problem of objectivity in the link between the court and the action, when engaging civil damages and environmental damages? In other words ¿ can we argue that the place of the harmful event can be determined independently of the persons involved? ¿Is favor Iaesi principle relevant in cases of environmental damage? We propose analyze those problems through the connections between International Civil Jurisdiction principles and environmental protection principles. In fact, environmental protection policy constitutes a "superior value". Therefore it affects directly the judge opinion about the connection link. Our approach is European, but the findings have universal validity.

    Lead is a recognized neurotoxicant, but estimating effects at the lowest measurable levels is difficult. An international pooled analysis of data from seven cohort studies reported an inverse and supra-linear relationship between blood lead concentrations and IQ scores in children. The lack...... of a clear threshold presents a challenge to the identification of an acceptable level of exposure. The benchmark dose (BMD) is defined as the dose that leads to a specific known loss. As an alternative to elusive thresholds, the BMD is being used increasingly by regulatory authorities. Using the pooled data...... yielding lower confidence limits (BMDLs) of about 0.1-1.0 μ g/dL for the dose leading to a loss of one IQ point. We conclude that current allowable blood lead concentrations need to be lowered and further prevention efforts are needed to protect children from lead toxicity....

  12. A shock and wear system under environmental conditions subject to internal failures, repair, and replacement

    International Nuclear Information System (INIS)

    Montoro-Cazorla, Delia; Pérez-Ocón, Rafael

    2012-01-01

    A system in a random environment is considered. The influence of the external conditions is governed by a Markovian arrival process. The internal structure of failure and repair are governed by phase-type distributions. The maintenance is performed by policy N. Under these assumptions, the Markov process governing the system is constructed, and it is studied in transient and stationary regime, calculating the availability and the rate of occurrence of failures. The renewal process due to the replacements of the system is studied, and expressions for the number of replacements and for the number of repairs between replacements are calculated. This paper extends other previously published since it incorporates a shock arrival process with dependence among the interarrival times and the renewal process associated to the replacements. A numerical application illustrates the calculations.

    Nov 2, 2014 marked the completion of the 14th year of continuous human presence in space on board the International Space Station (ISS). After 42 expedition crews, over 115 assembly & utilization flights, over 180 combined Shuttle/Station, US & Russian Extravehicular Activities (EVAs), the post-Assembly-Complete ISS continues to fly and the engineering teams continue to learn from operating its systems, particularly the life support equipment. Problems with initial launch, assembly and activation of ISS elements have given way to more long term system operating trends. New issues have emerged, some with gestation periods measured in years. Major events and challenges for each U.S. Environmental Control and Life Support (ECLS) subsystem occurring during calendar years 2010 through 2014 are summarily discussed in this paper, along with look-aheads for what might be coming in the future for each U.S. ECLS subsystem.

    The paper describes a regular events CITES consisting of young scientists school and international conference as a tool for training and professional growth. The events address the most pressing issues of application of information-computational technologies in environmental sciences and young scientists’ training, diminishing a gap between university graduates’ skill and concurrent challenges. The viability of the approach to the CITES organization is proved by the fact that single event organized in 2001 turned into a series, quite a few young participants successfully defended their PhD thesis and a number of researchers became Doctors of Science during these years. Young researchers from Russia and foreign countries show undiminishing interest to these events.

    Kohlhaas, Michael; Schumacher, Katja; Diekmann, Jochen; Schumacher, Dieter; Carmes, Martin

    2005-01-01

    In October 2003, the European Union introduced a Directive, which widens the scope of the EU's minimum taxation system from mineral oils to all energy products including coal, natural gas and electricity. It aims at reducing distortions that currently exist between Member States as well as between energy products. In addition, it increases previous minimum tax rates and thus the incentive to use energy more efficiently. The Directive will lead to changes in the energy tax schemes in a number of countries, in particular some southern Member Countries (Greece, Spain, Portugal) and most of the new Member States. In this paper, we analyze the effects of the EU energy tax harmonization with GTAP-E, a computable general equilibrium model. Particular focus is placed on the Eastern European countries, which became new members of the EU in May 2004. We investigate the effects of the tax harmonization on overall economic growth and sectoral development. Special attention is paid to international trade in order to analyze if competitiveness concerns, which have been forwarded in the context of energy taxation are valid. Furthermore, the effect on energy consumption and emissions and thus the contribution to the EU's climate change targets is analyzed

    A method, apparatus, and system for improved VA-TIRFM microscopy. The method comprises automatically controlled calibration of one or more laser sources by precise control of presentation of each laser relative a sample for small incremental changes of incident angle over a range of critical TIR angles. The calibration then allows precise scanning of the sample for any of those calibrated angles for higher and more accurate resolution, and better reconstruction of the scans for super resolution reconstruction of the sample. Optionally the system can be controlled for incident angles of the excitation laser at sub-critical angles for pseudo TIRFM. Optionally both above-critical angle and sub critical angle measurements can be accomplished with the same system.

  19. The Lisbon new international airport: The story of a decision-making process and the role of Strategic Environmental Assessment

    Partidario, Maria R.; Coutinho, Miguel

    2011-01-01

    This is the brief story of a decision process and the role of Strategic Environmental Assessment in government political decision-making. Following a prolonged, and agitated, decision process, initiated in the 1960s, the Government of Portugal in 2005 took the final decision to build the new international airport of Lisbon at the controversial location of Ota, 40 km north of Lisbon. The detailed project design and EIA were started. However this decision would change in 2007 due to the challenge raised by a private sponsored study that identified an alternative location for the airport at Campo de Tiro de Alcochete (CTA). This new site, which had never been considered as an option before, appeared to avoid many of the problems that caused public controversy at the Ota site. The Government, pressured by this challenge, promoted a strategic comparative assessment between the two sites. The result of this study was the choice of CTA as the preferred location. This paper discusses this radical change in the decision from a socio-political perspective. It will highlight the relevance of Strategic Environmental Assessment (SEA), and the strategic and constructive approach it enables in mega-project decision-making.

  20. International technology catalogue: Foreign technologies to support the environmental restoration and waste management needs of the DOE complex

    Matalucci, R.V.

    1995-07-01

    This document represents a summary of 27 foreign-based environmental restoration and waste management technologies that have been screened and technically evaluated for application to the cleanup problems of the Department of Energy (DOE) nuclear weapons complex. The evaluation of these technologies was initiated in 1992 and completed in 1995 under the DOE's International Technology Coordination Program of the Office of Technology Development. A methodology was developed for conducting a country-by-country survey of several regions of the world where specific environmental technology capabilities and market potential were investigated. The countries that were selected from a rank-ordering process for the survey included: then West Germany, the Netherlands, France, Japan, Taiwan, the Czech and Slovak Republics, and the Former Soviet Union. The notably innovative foreign technologies included in this document were screened initially from a list of several hundred, and then evaluated based on criteria that examined for level of maturity, suitability to the DOE needs, and for potential cost effective application at a DOE site. Each of the selected foreign technologies that were evaluated in this effort for DOE application were subsequently matched with site-specific environmental problem units across the DOE complex using the Technology Needs Assessment CROSSWALK Report. For ease of tracking these technologies to site problem units, and to facilitate their input into the DOE EnviroTRADE Information System, they were categorized into the following three areas: (1) characterization, monitoring and sensors, (2) waste treatment and separations, and (3) waste containment. Technical data profiles regarding these technologies include title and description, performance information, development status, key regulatory considerations, intellectual property rights, institute and contact personnel, and references

  2. Environmental mitigation for SCC initiation of BWR core internals by hydrogen injection during start-up

    International Nuclear Information System (INIS)

    Dozaki, K.; Abe, A.; Nagata, N.; Takiguchi, H.

    2004-01-01

    Hydrogen injection into the reactor water has been applied to many BWR power stations. Since hydrogen injected accelerates recombination of oxidant generated by water radiolysis, oxidant concentration, such as dissolved oxygen concentration in reactor water can be reduced. As the result of the reduction of oxidant concentration, Electrochemical Corrosion Potential (ECP) at the surface of structural material can be lowered. Lowered ECP moderates Stress Corrosion Cracking (SCC) sensitivity of structural materials, such as stainless steels. As usual, hydrogen injection system begins to work after the plant start-up is finished, when the condition of normal operation is established. Accordingly, Hydrogen Water Chemistry (HWC) does not cover all the period of plant operation. As far as SCC crack growth is considered, loss of HWC during plant start-up does not result in significant crack growth, because of duration of plant start-up is much shorter than that of plant normal operation, when HWC condition is being satisfied. However, the reactor water environment and load conditions during a plant start-up may contribute to the initiation of SCC. It is estimated that the core internals are subjected to the strain rate that may cause susceptibility to SCC initiation during start-up. Dissolved oxygen (DO) and hydrogen peroxide (H 2 O 2 ) has a peak, and ECP is in high levels during start-up. Therefore it is beneficial to perform hydrogen injection during start-up as well in order to suppress SCC initiation. We call it HWC During Start-up (HDS) here. (orig.)

  3. Best-Matched Internal Standard Normalization in Liquid Chromatography-Mass Spectrometry Metabolomics Applied to Environmental Samples.

    2018-01-16

    The goal of metabolomics is to measure the entire range of small organic molecules in biological samples. In liquid chromatography-mass spectrometry-based metabolomics, formidable analytical challenges remain in removing the nonbiological factors that affect chromatographic peak areas. These factors include sample matrix-induced ion suppression, chromatographic quality, and analytical drift. The combination of these factors is referred to as obscuring variation. Some metabolomics samples can exhibit intense obscuring variation due to matrix-induced ion suppression, rendering large amounts of data unreliable and difficult to interpret. Existing normalization techniques have limited applicability to these sample types. Here we present a data normalization method to minimize the effects of obscuring variation. We normalize peak areas using a batch-specific normalization process, which matches measured metabolites with isotope-labeled internal standards that behave similarly during the analysis. This method, called best-matched internal standard (B-MIS) normalization, can be applied to targeted or untargeted metabolomics data sets and yields relative concentrations. We evaluate and demonstrate the utility of B-MIS normalization using marine environmental samples and laboratory grown cultures of phytoplankton. In untargeted analyses, B-MIS normalization allowed for inclusion of mass features in downstream analyses that would have been considered unreliable without normalization due to obscuring variation. B-MIS normalization for targeted or untargeted metabolomics is freely available at https://github.com/IngallsLabUW/B-MIS-normalization .

    Each day, people in the communities of the Arctic face challenges to their health and well-being from changing climatic and environmental conditions and increasing levels of pollution to emerging infectious diseases. For this reason, it is critical that Arctic researchers and residents have access to timely, accurate, and relevant information addressing their unique concerns. To meet this need, the National Library of Medicine (NLM) and the University of Alaska Anchorage (UAA) have developed the Arctic Health website, www.arctichealth.org. The website provides an easy-to-use one-stop shop for information on the diverse health-related aspects of the Arctic region. It is organized around relevant topics, including climate change and environmental health, traditional healing and telehealth/telemedicine. The Arctic Health website provides links to the most reliable resources available from local, state, and international agencies, universities, and professional organizations. Two major goals of the site are to create a comprehensive, accessible repository for various media and a listing of research projects, past and present that relate to climate change and human health in the Arctic. To increase the site's relevance, the project has established and continues to create collaborations with researchers, communities, and other organizations to supply publications not available elsewhere, including gray literature, streaming video of traditional healers, and oral histories. These collaborations will also help ensure a database with a comprehensive list of research projects being done in the Arctic, from the international to the local level. Finding ways to negotiate the legal, cultural and national concerns of data sharing are a continuing job for the management team. All of this helps to create a system that will eventually track and ensure that data and reports from the research database translate to the publications database. As part of these efforts, the site is

  5. The Interplay between Social and Environmental Degradation in the Development of the International Political Economy*

    Directory of Open Access Journals (Sweden)

    Robert Biel

    2015-08-01

    Full Text Available This article considers capitalism as a dissipative system, developing at the expense of exporting disorder into two sorts of ‘environment’: the physical ecosystem; and a subordinate area of society which serves to nourish mainstream order without experiencing its benefits. Particularly significant is the relationship between the two forms of dissipation. The paper begins by assessing the dangers of translating systems theory into social relations, concluding that the project is nevertheless worthwhile, provided that exploitation and struggle are constantly borne in mind. Exploring the concepts of ‘core’ and ‘periphery,’ the paper highlights the contradictory nature of an attribute of chaos which is both ascribed to the out-group, and also really exported to it. If the core’s growth merely destroyed peripheral order, the entropy of capitalism would be starkly exposed in the form of an exhaustion of future room for maneuver. This problem can be kept at bay by maintaining a self-reproducing ‘low’ order within the subordinate social system; however the fundamental entropy is still there, and will sooner or later manifest itself in the shape of threats to the sustainability of that subordinate system. At the level of the international political economy (IPE, this dialectic unfolds against the background of a ‘lumpy’ development whereby (following structural crises order can be reconstituted, but at a cost which must be absorbed somewhere. In the case of the post-World War II reordering, this cost was massively exported to the physical environment. Since a high level of ecological depletion now appears permanently embedded within the capitalist IPE, future major efforts of order-building cannot rely on this dimension to the same degree, and must instead access some new forms of dissipative relationship with the social environment. The paper argues that this is the fundamental significance of the ‘sustainable development’ discourse: it

    Science.gov (United States)

    Ghosal, Sutapa; Wagner, Jeff

    2013-07-07

    We present correlated application of two micro-analytical techniques: scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) and Raman micro-spectroscopy (RMS) for the non-invasive characterization and molecular identification of flame retardants (FRs) in environmental dusts and consumer products. The SEM/EDS-RMS technique offers correlated, morphological, molecular, spatial distribution and semi-quantitative elemental concentration information at the individual particle level with micrometer spatial resolution and minimal sample preparation. The presented methodology uses SEM/EDS analyses for rapid detection of particles containing FR specific elements as potential indicators of FR presence in a sample followed by correlated RMS analyses of the same particles for characterization of the FR sub-regions and surrounding matrices. The spatially resolved characterization enabled by this approach provides insights into the distributional heterogeneity as well as potential transfer and exposure mechanisms for FRs in the environment that is typically not available through traditional FR analysis. We have used this methodology to reveal a heterogeneous distribution of highly concentrated deca-BDE particles in environmental dust, sometimes in association with identifiable consumer materials. The observed coexistence of deca-BDE with consumer material in dust is strongly indicative of its release into the environment via weathering/abrasion of consumer products. Ingestion of such enriched FR particles in dust represents a potential for instantaneous exposure to high FR concentrations. Therefore, correlated SEM/RMS analysis offers a novel investigative tool for addressing an area of important environmental concern.

    Purpose: To investigate the three-dimensional movement of internal fiducial markers placed near esophageal cancers using 320-multislice CT. Methods and Materials: This study examined 22 metal markers in the esophageal wall near the primary tumors of 12 patients treated with external-beam photon radiotherapy. Motion assessment was analyzed in 41 respiratory phases during 20 s of cine CT in the radiotherapy position. Results: Motion in the cranial-caudal (CC) direction showed a strong correlation (R 2 > 0.4) with the respiratory curve in most markers (73%). The average absolute amplitude of the marker movement was 1.5 ± 1.6 mm, 1.6 ± 1.7 mm, and 3.3 ± 3.3 mm in the left-right (LR), anterior-posterior (AP), and CC directions, respectively. The average marker displacements in the CC direction between peak exhalation and inhalation for the 22 clips were 1.1 mm (maximum, 5.5 mm), 3.0 mm (14.5 mm), and 5.1 mm (16.3 mm) for the upper, middle, and lower thoracic esophagus, respectively. Conclusions: Motion in primary esophagus tumor was evaluated with 320-multislice CT. According to this study, 4.3 mm CC, 1.5 mm AP, and 2.0 mm LR in the upper, 7.4 mm CC, 3.0 mm AP, and 2.4 mm LR in the middle, and 13.8 mm CC, 6.6 mm AP, and 6.8 mm LR in the lower thoracic esophagus provided coverage of tumor motion in 95% of the cases in our study population.

  11. Evidence for highly localized damage in internal tin and powder-in-tube Nb{sub 3}Sn strands rolled before reaction obtained from coupled magneto-optical imaging and confocal laser scanning microscopy

    Nb{sub 3}Sn strands for high-current, high-field magnets must be cabled before reaction while the conductor is still composed of ductile components. Even though still in the ductile, deformable state, significant damage can occur in this step, which expresses itself by inhomogeneous A15 formation, Sn leakage or even worse effects during later reaction. In this study, we simulate cabling damage by rolling recent high performance powder-in-tube (PIT) and internal tin (IT) strands in controlled increments, applying standard Nb{sub 3}Sn reaction heat treatments, and then examining the local changes using magneto-optical imaging (MOI), scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM). These combined characterizations allow any local damage to the filament architecture to be made clear. MOI directly reveals the local variation of superconductivity while CLSM is extremely sensitive in revealing Sn leakage beyond the diffusion barrier into the stabilizing Cu. These techniques reveal a markedly different response to deformation by the PIT and IT strands. The study demonstrates that these tools can provide a local, thorough, and detailed view of how strands degrade and thus complement more complex extracted strand studies.

    Mutual information exchange at international levels is important for practical application of global environment preservation technologies, whereas the APEC Virtual Center was established in fiscal 1997. Fiscal 1998 has discussed the future functions of the Virtual Center, and carried out the following matters to improve the functions and achieve its stable operation. Discussions were given on common use with the centers of other countries and regions of the specifications of classification systems for information areas and provided information that are provided by the Virtual Center. Visits were made to sub-managing countries and regions for smooth operation of the study groups, and opinions were exchanged. Visits were made to coordinators and contact points established in each country and region when the Center was founded in fiscal 1997. A visit was made to the U.S. Environmental Protection Agency to exchange opinions on coordination measures with the Cleaner Production Strategy of the U.S.A. being a project similar to the subject project. In order to strengthen the Japan's Center, attempts were made to expand the linking information to wider scope. Special pages publishing concentratedly the items of information that the users are interested were prepared as part of the information provision. (NEDO)

  17. The Elaborated Environmental Stress Hypothesis as a Framework for Understanding the Association between Motor Skills and Internalizing Problems: A mini-review

    Full Text Available Poor motor skills have been shown to be associated with a range of psychosocial issues, including internalizing problems (anxiety and depression. While well-documented empirically, our understanding of why this relationship occurs remains theoretically underdeveloped. The Elaborated Environmental Stress Hypothesis by Cairney, Rigoli, and Piek (2013 provides a promising framework that seeks to explain the association between motor skills and internalizing problems, specifically in children with Developmental Coordination Disorder (DCD. The framework posits that poor motor skills predispose the development of internalizing problems via interactions with intermediary environmental stressors. At the time the model was proposed, limited direct evidence was available to support or refute the framework. Several studies and developments related to the framework have since been published. This mini-review seeks to provide an up-to-date overview of recent developments related to the Elaborated Environmental Stress Hypothesis. We briefly discuss the past research that led to its development, before moving to studies that have investigated the framework since it was proposed. While originally developed within the context of DCD in childhood, recent developments have found support for the model in community samples. Through the reviewed literature, this article provides support for the Elaborated Environmental Stress Hypothesis as a promising theoretical framework that explains the psychosocial correlates across the broader spectrum of motor ability. This evidence promotes the external validity of the framework for use across the broader spectrum of motor ability. However, given its recent conceptualisation, ongoing evaluation of the Elaborated Environmental Stress Hypothesis is recommended.

    The design and manufacturing of the main Environmental Control and Life Support Systems (ECLSS) for the United States segments of the International Space Station (ISS) was an involved process that started in the late 1980's, with the assessment and testing of competing technologies that could be used to clean the air and recycle water. It culminated in 2009 with the delivery and successful activation of the Water Recovery System (WRS) water processor (WP). The ECLSS required the work of a team of engineers and scientist working together to develop systems that could clean and/or recycle human metabolic loads to maintain a clean atmosphere and provide the crew clean water. One of the main goals of the ECLSS is to minimize the time spent by the crew worrying about vital resources not available in the vacuum of space, which allows them to spend most of their time learning to live in a microgravity environment many miles from the comforts of Earth and working on science experiments. Microorganisms are a significant part of the human body as well as part of the environment that we live in. Therefore, the ISS ECLSS design had to take into account the effect microorganisms have on the quality of stored water and wastewater, as well as that of the air systems. Hardware performance issues impacted by the accumulation of biofilm and/or microbiologically influenced corrosion were also studied during the ECLSS development stages. Many of the tests that were performed had to take into account the unique aspects of a microgravity environment as well as the challenge of understanding how to design systems that could not be sterilized or maintained in a sterile state. This paper will summarize the work of several studies that were performed to assess the impacts and/or to minimize the effects of microorganisms in the design of a closed loop life support system.

    The recently developed environmental DNA (eDNA) analysis has been used to estimate the distribution of aquatic vertebrates by using mitochondrial DNA (mtDNA) as a genetic marker. However, mtDNA markers have certain drawbacks such as variable copy number and maternal inheritance. In this study, we investigated the potential of using nuclear DNA (ncDNA) as a more reliable genetic marker for eDNA analysis by using common carp (Cyprinus carpio). We measured the copy numbers of cytochrome b (CytB) gene region of mtDNA and internal transcribed spacer 1 (ITS1) region of ribosomal DNA of ncDNA in various carp tissues and then compared the detectability of these markers in eDNA samples. In the DNA extracted from the brain and gill tissues and intestinal contents, CytB was detected at 95.1 ± 10.7 (mean ± 1 standard error), 29.7 ± 1.59 and 24.0 ± 4.33 copies per cell, respectively, and ITS1 was detected at 1760 ± 343, 2880 ± 503 and 1910 ± 352 copies per cell, respectively. In the eDNA samples from mesocosm, pond and lake water, the copy numbers of ITS1 were about 160, 300 and 150 times higher than those of CytB, respectively. The minimum volume of pond water required for quantification was 33 and 100 mL for ITS1 and CytB, respectively. These results suggested that ITS1 is a more sensitive genetic marker for eDNA studies of C. carpio. © 2016 John Wiley & Sons Ltd.

    Gamma-ray scanning, often referred to as 'column scanning', is a convenient, cost effective, fast, efficient and non-invasive technique to examine internal characteristics of a certain equipment, like alcohol distillation columns, while it is in operation. Column scanning allows to engineers, to study hydraulics tray inside of distillation column in on-line condition. It provides essential data to optimize the performance of columns, extend column run times, to evaluate effects of defective track and to identify maintenance requirements. This knowledge can reduce repair times significantly. In the year 2014, the Environmental Radiological Surveillance Laboratory from Center of Radiation Protection and Hygiene, introduced this service in the 'Hector Molina' Distillery. The diagnosis carried out allowed the detection of some anomalies in its operation. In this work the results obtained during gamma-ray scanning of the column are shown. (Author)

    Day, George S; Schoemaker, Paul J H

    2005-11-01

    Companies often face new rivals, technologies, regulations, and other environmental changes that seem to come out of left field. How can they see these changes sooner and capitalize on them? Such changes often begin as weak signals on what the authors call the periphery, or the blurry zone at the edge of an organization's vision. As with human peripheral vision, these signals are difficult to see and interpret but can be vital to success or survival. Unfortunately, most companies lack a systematic method for determining where on the periphery they should be looking, how to interpret the weak signals they see, and how to allocate limited scanning resources. This article provides such a method-a question-based framework for helping companies scan the periphery more efficiently and effectively. The framework divides questions into three categories: learning from the past (What have been our past blind spots? What instructive analogies do other industries offer? Who in the industry is skilled at picking up weak signals and acting on them?); evaluating the present (What important signals are we rationalizing away? What are our mavericks, outliers, complainers, and defectors telling us? What are our peripheral customers and competitors really thinking?); and envisioning the future (What future surprises could really hurt or help us? What emerging technologies could change the game? Is there an unthinkable scenario that might disrupt our business?). Answering these questions is a good first step toward anticipating problems or opportunities that may appear on the business horizon. The article concludes with a self-test that companies can use to assess their need and capability for peripheral vision.

    In march 1994 the Central Planning Bureau (CPB) in the Hague, the National Institute of Public Health and Environmental Protection (RIVM) in Bilthoven and the Institute of Environmental Studies (IES) in Amsterdam started the first phase of a joint research program aimed at creating integrated scenarios of the global economy, GHG emissions, and climate impacts. The goal of the first phase of this project was to design and test a linked version of the economic model WORLD SCAN of the former, and the climate model IMAGE 2 of the latter institute. This first phase has resulted in the planned test runs with an operational version of the linked models by May 1995. The experiences in the first year were encouraging, both in the scientific and the organizational sense. In a sense, a link was made between scientific disciplines: a coupling of disciplines concerning with global economic development and the global physical climate system is difficult and novel. The goal of the project was to integrate long-term economic developments and effects of climate change. Both the WORLD SCAN model and IMAGE 2 provide a consistent analysis of the global system, but from different perspectives. IMAGE 2 simulates climate change and its effects in a global context but treats the economic system as exogenous. WORLD SCAN covers the world economic system in a consistent manner but does not take into account the global environment. The links are constructed in the area of agriculture and energy. The basic idea is that WORLD SCAN determines demand and supply on economic principles, while IMAGE 2 provides information on changes of land area and average quality of productive land, and other damage costs based on its three sub-systems. The demand for energy is fed into IMAGE 2's Energy Industry subsystem (EIS), which in turn determines emissions of greenhouse gases. Furthermore, some additional output from WORLD SCAN on activity levels, prices and capital structure can be used to determine

    The environmental performance indicators in the tourism sector represents the necessary element to quantify and to simplify information about the environmental performance of a particular field in order to make the comprehension of the interactions between tourist activities and environment understood by the customers and decision makers. This indicators will have to be quantified in order to contribute to focus and explain improvements in environmental management. One of the most important elements to pursue a Sustainable Development is the definition of a series of the right indicators. Basically performance indicators can be applied in the environmental analyses effected for defining the politics of management of tourist development and, particularly, in the procedures of Environmental Impact Assessment and Strategic Environmental Assessment disciplined by the European Directives 85/337/CEE, 97/11/CEE, from the proposal of Directive on the SEA and from the relative national normative. This tools should allow to esteem environmental conditions and the impacts caused by the tourist activities to find actions to balance the budget between the economic development and the social and environmental issues i a determined territorial context [it
