  1. Active fault and other geological studies for seismic assessment: present state and problems

    International Nuclear Information System (INIS)

    Evaluation system of earthquakes from an active fault is, in Japan, based on the characteristic earthquake model of a wide sense that postulates essentially the same (nearly the maximum) magnitude and recurrence interval during the recent geological times. Earthquake magnitude M is estimated by empirical relations among M, surface rupture length L, and surface fault displacement D per event of the earthquake faults on land in Japan. Recurrence interval R of faulting/earthquake is calculated from D and the long-term slip rate S of a fault as R=D/S. Grouping or segmentation of complicatedly distributed faults is an important, but difficult problem in order to distinguish a seismogenic fault unit corresponding to an individual characteristic earthquake. If the time t of the latest event is obtained, the 'cautiousness' of a fault can be judged from R-t or t/R. According to this idea, several faults whose t/R exceed 0.5 have been designated as the 'precaution faults' having higher probability of earthquake occurrence than the others. A part of above evaluation has been introduced at first into the seismic-safety examination system of NPPs in 1978. According to the progress of research on active faults, the weight of interest in respect to the seismic hazard assessment shifted gradually from the historic data to the fault data. Most of recent seismic hazard maps have been prepared in consideration with active faults on land in Japan. Since the occurrence of the 1995 Hyogoken-Nanbu earthquake, social attention has been concentrated upon the seismic hazard due to active faults, because this event was generated from a well-known active fault zone that had been warned as a 'precaution fault'. In this paper, a few recent topics on other geological and geotechnical researches aiming at improving the seismic safety of NPPs in Japan were also introduced. (J.P.N.)

  3. United States panel presentations

    International Nuclear Information System (INIS)

    Before I begin I have to make a disclaimer. That is that I am going to be talking about public perception because I think that is very important. But I do not want to give the impression that I think the public is wrong. I happen to agree with the public's perception of nuclear power, and I want to make that clear. I do not like the current generation of nuclear plants as I have made clear in many statements that I have made. On the other hand, in the long term, I feel that we have only two choices on the supply side, and that is nuclear power and solar electricity. And although I think solar electricity has the best chance, I am realistic enough to know that technologies do not always work the way I want. And so I think it is necessary to have at least some kind of nuclear option available. On the other hand, I do not think just any kind of nuclear technology will do. I want to talk to you about the conditions that I think you have to take into account when you try to design reactors that are publicly acceptable. I look at this as an insurance policy. Again, I do not want to be misquoted: I think nuclear power should be considered as an insurance policy, not as our first line of defense. Having made those disclaimers, what we need to do is set out a problem statement. The problem statement I set out is, 'How could one design and demonstrate a nuclear reactor that would regain public confidence in the United States, if one chose to do that?' By regaining confidence, I mean regaining sufficient confidence to site reactors at a number of locations. It is a pretty heavy task because the public cannot judge the technical issues. They have to judge the players by their characters and their histories, just as the way we calibrate anyone that knows things that we do not. I have three theses that I think are crucial. The first is that people do not believe in the claims of advocates, of any point of view, not just nuclear power, once the advocates have been proved wrong on

  5. Present and potential nitrogen outputs from Norwegian soft water lakes – an assessment made by applying the steady-state First-order Acidity Balance (FAB model

    Full Text Available The steady-state First-order Acidity Balance (FAB model for calculating critical loads of sulphur (S and nitrogen (N is applied to 609 Norwegian soft-water lakes to assess the future nitrate (NO3‾ leaching potential under present (1992-96 S and N deposition. The lakes were separated into five groups receiving increasing levels of N deposition (-2yr-1. Using long-term sustainable N sink rates presently recommended for FAB model applications, N immobilisation, net N uptake in forests, denitrification and in-lake N retention were estimated for each group of lakes. Altogether, the long-term N sinks constituted 9.9 ± 3.2 to 40.5 ± 11.4 meq m-2yr-1 in the lowest and highest N deposition categories, respectively. At most sites, the current N deposition exceeds the amount of N retained by long-term sustainable N sinks plus the NO3‾ loss via the lake outlets. This excess N, which is currently retained within the catchments may, according to the FAB model, leach as acidifying NO3‾ in the future. If these predictions are fulfilled, NO3‾ leaching at sites in the various N deposition categories will increase dramatically from present (1995 mean levels of 1-20 meq m-2yr-1, to mean levels of 7-70 meq m-2yr-1 at future steady state. To illustrate the significance of such an increase in NO3‾ leaching, the mean Acid Neutralising Capacity (ANC at sites in the highest N deposition category may decrease from -18 ± 15 μeq L-1 at present, to -40 ± 20 μeq L-1. Under present S and N deposition levels, the FAB model predicts that 46% of the Norwegian lakes may experience exceedances of critical loads for acidifying deposition. In comparison, the Steady-State Water Chemistry model (SSWC, which considers only the present N leaching level, estimates critical load exceedances in 37% of the lakes under the same deposition level. Thus far, there are great uncertainties regarding both the time scales and the extent of future N leaching, and it is largely unknown

    2010-01-01

    The Energy Independence and Security Act of 2007 (EISA), Section 712, authorizes the U.S. Department of the Interior to develop a methodology and conduct an assessment of the Nation's ecosystems focusing on carbon stocks, carbon sequestration, and emissions of three greenhouse gases (GHGs): carbon dioxide, methane, and nitrous oxide. The major requirements include (1) an assessment of all ecosystems (terrestrial systems, such as forests, croplands, wetlands, shrub and grasslands; and aquatic ecosystems, such as rivers, lakes, and estuaries), (2) an estimation of annual potential capacities of ecosystems to increase carbon sequestration and reduce net GHG emissions in the context of mitigation strategies (including management and restoration activities), and (3) an evaluation of the effects of controlling processes, such as climate change, land use and land cover, and wildlfires. The purpose of this draft methodology for public review is to propose a technical plan to conduct the assessment. Within the methodology, the concepts of ecosystems, carbon pools, and GHG fluxes used for the assessment follow conventional definitions in use by major national and international assessment or inventory efforts. In order to estimate current ecosystem carbon stocks and GHG fluxes and to understand the potential capacity and effects of mitigation strategies, the method will use two time periods for the assessment: 2001 through 2010, which establishes a current ecosystem GHG baseline and will be used to validate the models; and 2011 through 2050, which will be used to assess future potential conditions based on a set of projected scenarios. The scenario framework is constructed using storylines of the Intergovernmental Panel on Climate Change (IPCC) Special Report Emission Scenarios (SRES), along with initial reference land-use and land-cover (LULC) and land-management scenarios. An additional three LULC and land-management mitigation scenarios will be constructed for each

  8. Present states of radiopharmaceuticals unregistered in Japan

    International Nuclear Information System (INIS)

    Described are present states of radiopharmaceuticals (RP) registered abroad but yet unregistered in Japan, together with their clinical and basic findings, essentially aiming at their early introduction in the country. Most of RP registered and to be approved in the nearest future either by Food and Drug Administration (FDA) or European Medicines Agency (EMA) are subjected to this paper. Clinical and basic features of those RP are mainly explained about their development and registration process, clinical outcome, pharmacokinetics and safety items like adverse reactions. Unregistered RP in Japan listed in this paper include total 18 RP: for therapy; 223Ra-radium chloride, 131I-tositumomab, 153Sm-lexidronam pentasodium, 90Y-yttrium chloride: for PET; 13N-ammonia, 18F-florbetapir, -fluorocholine, -fluorodopa, -fluoride, 82Rb-rubidium chloride: and for SPECT; 99mTc-arcitumomab, -sulesomab, -fanolesomab, -besilesomab, -red blood cells, 123I-ioflupane, 111In-pentetreotide, and -capromab pendetide. As well, also listed are those RP registered abroad but not actually marketed: 99mTc-apcitide, -depreotide, -nofetumomab and 111In-satumomab pendetide: and those registered by FDA as medical devices, not as RP, 90Y-microsphere and -glass microsphere, since which are to be given in the body similarly to RP. In development of RP, economical (commercial) problems are pointed out to be a rather globally common task and it is a fact that there are RP registered in Japan alone such as 123I-iofetamine and -iomazenil, of which registration has been either abandoned or not conducted in foreign countries.

  9. State of risk assessment

    International Nuclear Information System (INIS)

    In view of the growing importance assumed in recent years by scientific work on the calculation, quantification, evaluation and acceptance as well as behavior in the face of risks in general and more specifically, the risks of large industrial plants, the report attempts to provide a survey of the current situation, results and evaluation of this new branch of research, risk assessment. The emphasis of the report is on the basic discussion and criticism of the theoretical and methodological approaches used in the field of risk assessment (section 3). It is concerned above all with - methodical problems of determining and quantifying risks (3.1) - questions of the possibility of risk evaluation and comp arison (3.1, 3.2) - the premises of normative and empirical studies on decision making under risk (3.2, 3.3) - investigations into society's acceptance of risks involved in the introduction of new technologies (3.4) - attempts to combine various aspects of the field of risk assessment in a unified concept (3.5, 3.6, 3.7). Because risk assessment is embedded in the framework of decision theory and technology assessment, it can be implicitly evaluated at a more general level within this framework, as far as its possibilities and weaknesses of method and application are concerned (section 4). Sections 2 and 5 deal with the social context of origin and utilization of risk assessment. Finally, an attempt is made at a summary indicating the possible future development of risk assessment.

  11. Present state of radiosterilization of medical products

    International Nuclear Information System (INIS)

    Standards of the methods for radiosterilization were first gazetted in 1970 in Japan and have been studied especially according to the practical experience. 2.5 M rad is generally used as a dose for sterility assurance with a surviving probability of bacteria of 10-6. In determining the actual dose, it is necessary to burden indicator bacteria to the objective medical products to reproduce the state of the attachment of contamination bacteria. Simultaneously, it should be noted whether or not materials composing the product are changed due to radiation. In performing radiosterilization, the following three systems are used: (1) continuous motion system in which cardboards containing medical products move at a given rate surrounding the source, (2) shuffle and dwell system in which they are kept in a case for irradiation and move in an irradiation chamber, and (3) the system in which they pass through the source frames arranged in parallel. The management during the process of radiosterilization is the same as that of the other sterilization methods. A test for sterility assurance is sometimes considered unnecessary, if the management during radiosterilization is complete. However, a bacteriological test using biological indicators and an extraction test for sterility assurance are combined in Japan. (Namekawa, K.)

    We present a recently developed method of potential analysis of time series data, which comprises (1) derivation of the number of distinct global states of a system from time series data, and (2) derivation of the potential coefficients describing the location and stability of these states, using the unscented Kalman filter (UKF). We test the method on artificial data and then apply it to climate records spanning progressively shorter time periods from 5.3 Myr ago to the recent observational record. We detect various changes in the number and stability of states in the climate system. The onset of Northern Hemisphere glaciation roughly 3 Myr BP is detected as the appearance of a second climate state. During the last ice age in Greenland, there is a bifurcation representing the loss of stability of the warm interstadial state, followed by the total loss of this state around 25 kyr BP. The Holocene is generally characterized by a single stable climate state, especially at large scales. However, in the historical record, at the regional scale, the European monthly temperature anomaly temporarily exhibits a second, highly degenerate (unstable) state during the latter half of the eighteenth century. At the global scale, temperature is currently undergoing a forced movement of a single stable state rather than a bifurcation. The method can be applied to a wide range of geophysical systems with time series of sufficient length and temporal resolution, to look for bifurcations and their precursors. (orig.)

    In this survey of the Andersen-Lempert theory we present the state of the art in the study of the density property (which means that the Lie algebra generated by completely integrable holomorphic vector fields on a given Stein manifold is dense in the space of all holomorphic vector fields). There are also two new results in the paper one of which is the theorem stating that the product of Stein manifolds with the volume density property possesses such a property as well. The second one is a meaningful example of an algebraic surface without the algebraic density property. The proof of the last fact requires Brunella's technique.

    2010-05-01

    In order to protect waters from damages, improve water-environmental quality and mitigate water-related disasters need the advanced science and technology, sufficient investment and appropriate management. All of these need an effective education and training in the hydrology as the part of water - related sciences. The education in the hydrology is the part of national water-related activity in Ukraine. The needs in the quality of hydrological education will increase as the introduction of new ideas and techniques into practice of water resources planners and managers become comparative. Environmentally oriented water resources development, inherent challenges of man-made and climate change impact on waters have to be tackled worldwide by well trained engineers and scientist relying on modern technology. Ukraine has more than 70 years of experience in the training of hydrologists. At the present hydrologists of B.Sc., M. Sc. and Ph D levels are trained at the Odesa State Environmental University (on the engineering basis) and at the Faculty of Geography of the Kyiv National University (on the geographical basis). The Geographical training of hydrologists at the Kyiv National University provides deeper understanding of natural processes in rivers, lakes and reservoirs, to view them in geographical complex with other physiogeographical phenomena. For this purpose students study geology, geomorphology, biology, meteorology, soil science, physical geography etc. The graduate hydrologists work in the organizations of the State Hydrometeorological Service, the State Committee for Water Management, the Academy of Sciences, others governmental and private organizations. The requirements for hydrologists of these organizations are different in context and scope. This leads to the conclusion that a level of training of hydrologists should have a wide-scope in education. This is achieved by the university-wide fundamental and general geographic training during first and

  8. Present state of nuclear power business in China

    International Nuclear Information System (INIS)

    This article presented present state of nuclear power business in China based on latest information obtained at visit at nuclear power related facilities in December 2010. China Atomic Energy Authority (CAEA) promoted nuclear power, while National Nuclear Safety Administration (NNSA) was an independent regulatory body of nuclear power. Construction of nuclear power was promoted by three national nuclear engineering development corporations: China National Nuclear Corporation (CNNC), China Guangdon Nuclear Power Corporation (CGNPC) and State Nuclear Power Technology Corporation (SNPTC). In China, 13 nuclear power reactors were in operation and 27 under construction. Shortage of nuclear engineers became evident with rapid growth of nuclear power, which forced delay of nuclear power construction schedule. Future strategies of reactor type varied domestic, French and US ones respectively dependent on CNNC, CGNPC and SNPTC, CNNC seemed to change from third generation reactor (CNP 1000) to second one (CP 1000) due to regulatory licensing difficulty of NNSA. As for advanced reactor development, large scale PWR project, HTR project and FBR development project were proceeding. As HTR project was selected as high-priority project, an experimental reactor (HTR-10) was critical in 2000 and construction of demonstration reactor started in 2009. (T. Tanaka)

    Full Text Available Since admission of Poland to the European Union Polish enterprises can make use of the state support in various forms including support in investments, investigations and developments, consulting, higher qualification, financing of exhibition participation, salary additional payments for invalid workers, repayment of loan portions. The purpose of the given publication is to make an analysis of accounting method for state support which is granted for an organization within the frameworks of the accounting policy depending on the obtained grants.Enterprises must select themselves a grant accounting form as in account books so while presenting financial reporting and these accounting and reporting forms must be reflected in the enterprise policy of accounting. The enterprise accounting policy indicates principles for creation of reserves and conditional obligations related with grants. Enterprises can use some simplifications and they can exclude creation of reserves and withhold conditional obligations concerning the grants if these measures are considered as insignificant.In accordance with the enterprise accounting policy account books must contain recordings on grant provision when a grant is transferred to the bank account or when an enterprise receives a written notice confirming final decision about payments from a financing institution. The accounting policy must determine principles of bank operation break-up on grant accounts and security system of data and files including accounting documents, accounts and other documents related to the obtained grant and the required archivation term

    Full Text Available The purpose of this study was to replicate the research of Davis (1989 to test the decision usefulness of different information presentations as alternatives to financial information that would normally be represented as numbers. A laboratory experiment, based upon Davis’ (1989 study, was conducted using a within subject experimental design to test for information effects. The experiment consisted of two groups with fifteen subjects in each. Decision usefulness was measured from the perspective of a user’s efficiency and effectiveness (operationalised as accuracy and response time in answering questions of different levels of complexity. Evidence of the superior effectiveness and efficiency of one form of information presentation over another was found only at the lowest level of question complexity. The results of this study are not consistent across the range of findings expressed by Davis (1989 and So and Smith (2004. The model does however provide a robust tool for assessing the decision usefulness of different forms of information presentations. The restricted number of subjects and the use of surrogates may present as a limitation to generalisability. However, the nature of the financial information and the task were suitably matched to the expectations of the knowledge and experience of the student surrogates. The results suggest that tables, bar graphs and line graphs are appropriate information presentations to use in general purpose financial reports when decision performance is being measured in terms of a user’s efficiency and effectiveness.

    1990-11-01

    This minireview presents the state of the art with respect to automated detection of micronuclei (MN) in binucleated lymphocytes. Emphasis is on an image analysis technique, based on the principles of mathematical morphology (pattern recognition), which combines a personal computer with an image processing board and a board for microscope control. The basic idea behind this procedure is that nuclei plus MN and cytoplasms are analysed separately and sequentially by capturing images from gallocyanin-stained nuclei plus MN and naphthol yellow-S stained cytoplasms from one microscope field by using different filters. Major steps in the identification of nuclei and MN are separation of nuclei and MN from background by determination of periphery of the nuclei and MN, and artefact rejection procedures. After changing the filter, a binary image is constructed from cytoplasms and artefacts. Finally, stored information from selected binucleated objects with/without MN is combined with the cytoplasm image to check whether selected objects belong to the same cytoplasm. The procedure described above allows automated detection of binucleated lymphocytes with or without MN. The current capacity to detect 63% of binucleated cells and 57% of the MN within them is quite acceptable. To avoid false positives, artefact rejection procedures need to be improved before the method can be used routinely. PMID:1977825

    Full Text Available Apart from very contaminated spatial areas, there are places with attractive and non-polluted environment, that are suitable for tourism and recreation. Such places are spa resorts, characterized by numerous and various natural elements having significant health and recreative functions (thermo-mineral springs, rare gases, favorable climatic conditions, rich vegetation, etc., which attract attention of ample tourist demand. Serbia is welknown as a 'country of spa resorts', because of a great number of thermo-mineral springs, long tradition and their significance for tourism economy. Official statistical service keeps records of tourist flows only at 30 spa resorts (approximately, having participation at 95% of the total tourist trade in Serbia's spas. The topic of this paper is devoted to estimation of the present state and perspectives of spa tourism in Serbia. Special attention is focused on: analysis of resources for spa tourism, discussion of key factors for tourist valorization of Serbia's spas, investigation of structural features of spa tourism, comparison of Serbia's experiences in domain of spa tourism with contemporary trends in certain spa resorts in other European countries, and, finally, defining the most important tasks for spa tourism improvement.

  16. Assessment of UF6 Equation of State

    2009-02-11

    A common assumption in the mathematical analysis of flows of compressible fluids is to treat the fluid as a perfect gas. This is an approximation, as no real fluid obeys the perfect gas relationships over all temperature and pressure conditions. An assessment of the validity of treating the UF{sub 6} gas flow field within a gas centrifuge with perfect gas relationships has been conducted. The definition of a perfect gas is commonly stated in two parts: (1) the gas obeys the thermal equation of state, p = {rho}RT (thermally perfect), and, (2) the gas specific heats are constant (calorically perfect). Analysis indicates the thermally perfect assumption is valid for all flow conditions within the gas centrifuge, including shock fields. The low operating gas pressure is the primary factor in the suitability of the thermally perfect equation of state for gas centrifuge computations. UF{sub 6} is not calorically perfect, as the specific heats vary as a function of temperature. This effect is insignificant within the bulk of the centrifuge gas field, as gas temperatures vary over a narrow range. The exception is in the vicinity of shock fields, where temperature, pressure, and density gradients are large, and the variation of specific heats with temperature should be included in the technically detailed analyses. Results from a normal shock analysis incorporating variable specific heats is included herein, presented in the conventional form of shock parameters as a function of inlet Mach Number. The error introduced by assuming constant specific heats is small for a nominal UF{sub 6} shock field, such that calorically perfect shock relationships can be used for scaling and initial analyses. The more rigorous imperfect gas analysis should be used for detailed analyses.

    This article reported present state of nuclear power and electric power business in United States and Europe after Fukushima Daiichi Accident. As for the trend of demand and supply of electric power and policy, the accident forced Germany possibly to proceed with phase-out of nuclear power, but France and United States to sustain nuclear power with no great change of energy policy at this moment. As for the trend of electric power market, there was not state in United States with liberalized retail market of electric power after rolling blackouts occurred in California State in the early 2000s. In Germany proceeding with renewable energy introduction, renewable electricity fed into the grid was paid for by the network operators at fixed tariffs and the costs passed on to electricity consumers were increasing. Renewable Portfolio Standards (RPS) in United States forced the state to introduction of renewable energy to some ratio, and Feed-in Tariff (FIT) introduced in EU in 1990s lead to introduction of a large amount of renewable electricity targeted in 2020. Huge amount of wind power introduction brought about several problems to solve such that excess electric power above domestic demand had bad effects on grids in neighboring region. Enforcement of power transmission lines was also needed with increase of maximum electric power as well as introduction of a large amount of renewable electricity. (T. Tanaka)

  3. Assessing Lay Understanding of Common Presentations of Earthquake Hazard Information

    Science.gov (United States)

    Thompson, K. J.; Krantz, D. H.

    2010-12-01

    The Working Group on California Earthquake Probabilities (WGCEP) includes, in its introduction to earthquake rupture forecast maps, the assertion that "In daily living, people are used to making decisions based on probabilities -- from the flip of a coin (50% probability of heads) to weather forecasts (such as a 30% chance of rain) to the annual chance of being killed by lightning (about 0.0003%)." [3] However, psychology research identifies a large gap between lay and expert perception of risk for various hazards [2], and cognitive psychologists have shown in numerous studies [1,4-6] that people neglect, distort, misjudge, or misuse probabilities, even when given strong guidelines about the meaning of numerical or verbally stated probabilities [7]. The gap between lay and expert use of probability needs to be recognized more clearly by scientific organizations such as WGCEP. This study undertakes to determine how the lay public interprets earthquake hazard information, as presented in graphical map form by the Uniform California Earthquake Rupture Forecast (UCERF), compiled by the WGCEP and other bodies including the USGS and CGS. It also explores alternate ways of presenting hazard data, to determine which presentation format most effectively translates information from scientists to public. Participants both from California and from elsewhere in the United States are included, to determine whether familiarity -- either with the experience of an earthquake, or with the geography of the forecast area -- affects people's ability to interpret an earthquake hazards map. We hope that the comparisons between the interpretations by scientific experts and by different groups of laypeople will both enhance theoretical understanding of factors that affect information transmission and assist bodies such as the WGCEP in their laudable attempts to help people prepare themselves and their communities for possible natural hazards.

    The paper presented assessment of sealed fire states in underground coal mines by so-called "fire characteristic", which graphically described tendencies of fire gas components - oxygen, nitrogen, carbon dioxide, carbon monoxide and hydrocarbons - in time. In order to mark gas components tendencies in time the authors applied the time series analysis. The case studied confirmed, that analysis of fire gas components tendencies in time and their correlation allow to elicit proper conclusions about fire state assessment. Assessment of fire states based on single value of fire indexes without considering their trends in time and correlation between trends of gas components would give wrong results. The suggested method can appropriately indicate fire states in a sealed area.

    2006-11-01

    The evaluation of QOL (Quality of Life) in the medical field has revolved around the development of self-measurement scales comprising two or more questions based on psychometric theory. QOL research in the field of child health progressed in the latter half of the 80s in the United States, and aspects of ambiguity and adaptation to the environment of children were recognized. Objective health and subjective health differ significantly among children and are strongly influenced by environmental factors. In addition, QOL in early life anticipates the later health status in adolescence and youth. For these reasons, QOL research in the field of child health is very important. More than 20 scales, exemplified by CHQ, PedsQL, TACQOL/TAPQOL, and COOP charts, exist as standard generic QOL indices for children. Disease-specific scales cover epilepsy, asthma, and allergic disease, as discussed in a number of early studies. Diabetes, skin disease, and cancer are also major research subjects. Self-evaluation is one of the principles of QOL research; it is stated that children in the age group of 5-6 years are already capable of expressing pain and their physical condition and that the competency to describe abstract concepts such as pride and happiness matures around the age of 9-10 years. Sources of information such as the computer have developed and spread remarkably in recent years. The use of such technology facilitates the evaluation of young children with a high level of accuracy. The problems currently faced are the low reliability of responses of children, difficulties in cross-cultural comparison, and transformation of the sense of values according to growth. In conclusion, the development of QOL research in the field of child health should allow realization of an improved health situation in which children's points of view are included in the decision-making process for required treatments and health care policy. Further, health administration can be expected to

    2015-10-01

    Myofibrillar myopathies (MFM) have been described in the mid-1990s as a group of diseases sharing common histological features, including an abnormal accumulation of intrasarcoplasmic proteins, the presence of vacuoles and a disorganization of the intermyofibrillar network beginning at the Z-disk. The boundaries of this concept are still uncertain, and whereas six genes (DES, CRYAB, LDB3/ZASP, MYOT, FLNC and BAG3) are now classically considered as responsible for MFM, other entities such as FHL1 myopathy or Hereditary Myopathy with Early Respiratory Failure linked to mutations of titin can now as well be included in this group. The diagnosis of MFM is not always easy; as histological lesions can be focal, and muscle biopsy may be disappointing; this has led to a growing importance of muscle imaging, and the selectivity of muscle involvement has now been described in several disorders. Due to the rarity of these myopathies, if some clinical patterns (such as distal myopathy associated with cardiomyopathy due to desmin mutations) are now well known, surprises remain possible and should lead to systematic testing of the known genes in case of a typical histological presentation. In this paper, we aim at reviewing the data acquired on the six main genes listed above as well as presenting the experience from two French reference centres, Paris and Marseilles. PMID:26342832

  19. Present state of the controversy about the grain boundary relaxation

    International Nuclear Information System (INIS)

    An analysis of the internal friction produced by grain boundary relaxation in metals, alloys and ceramics is presented. The different interpretations given in the literature to relaxation phenomena occurring at temperatures above about half the melting point which include the influence of grain boundaries and their interaction with solutes and precipitates are discussed in detail. A complete set of the experimental data disposable in this field since 1972 until today is reviewed. Finally, some recent experiments are discussed and new ones are suggested. They might solve the actual controversy about the real origin of the relaxation phenomena observed. If this is the case, a considerable amount of information already published can be taken into account with a good degree of confidence. This information contributes to the description of the structure and behaviour of grain boundaries, both being important topics for materials science. (author). 119 refs, 21 figs, 1 tab

    In the era of information technology, the elderly and disabled can be monitored with numerous intelligent devices. Sensors can be implanted into their home for continuous mobility assistance and non-obtrusive disease prevention. Modern sensor-embedded houses, or smart houses, cannot only assist people with reduced physical functions but help resolve the social isolation they face. They are capable of providing assistance without limiting or disturbing the resident's daily routine, giving him or her greater comfort, pleasure, and well-being. This article presents an international selection of leading smart home projects, as well as the associated technologies of wearable/implantable monitoring systems and assistive robotics. The latter are often designed as components of the larger smart home environment. The paper will conclude by discussing future challenges of the domain. PMID:18367286

  2. Present state of hydro power development in Austria

    International Nuclear Information System (INIS)

    The austrian electricity is based on a combination of hydro and thermal production with the main contribution coming from hydro power. About 70% of the total Austrian electricity demands is covered by hydro power. Due to its location in the Alps, Austria has an exploitable hydro power potential of approx. 56 TWh/a (including small plants and renewals) of which only about 70% is being used at the moment. Thus there is quite a remarkable potential that is still to be exploited mainly in Tyrol and along the Danube east of Vienna. In order to stimulate the further exploitation of hydro power, fuel costs for oil and gas would have to be noticeably raised at simultaneous reduction of costs for hydro power plants. From the strictly technical point of view, cost reductions - even when reducing safety and availability requirements -are of minor importance. Hydro power plants can never be produced in series production and the same time they are multi-purpose plants serving - apart from electricity generation - also for improving conditions for navigation, bed stabilisation (on the Danube), ground water management, flood prevention, drinking water supply and infrastructure. Thus they are important for the national economy and environmental protection measures account for up to 30% of total plant costs. Accompanying measures are nowadays an absolute must in state-of-the-art power station planning and they have to be paid for. Attempts to reduce the costs should be directed towards cost sharing in view of the plant's multiple advantages: those who draw advantage from the plant should also participate in the financing. So far financial contribution was only made by the Federal Government for the improvement of conditions for navigation on the Danube. In the case of the power station Freudenau the the Republic of Austria provided for ATS 1.5 billion, for previous plants the contribution amounted 30% of total costs.

  4. Present state of the combined treatment with radiation and chemicals

    International Nuclear Information System (INIS)

    Of malignancies in which the results have been markedly improved by combined treatment with radiation and chemicals for the past decade, non-Hodgkin's lymphoma localized in head and neck and intra-oral carcinoma are presented. In the management of non-Hodgkin's lymphoma, the authors stressed the following: 1) Rappaport's classification has been a help to evaluate the prognosis; 2) lymphoma of the Waldeyer's ring should not be included in nodal lymphoma, and also it should be separated from extranodal lymphoma as well, because of different prognosis; 3) It seems that some kinds of chemotherapy would have a role in improving the results of radiotherapy in the management of radiotherapy, even in localized cases. In some types of intra-oral carcinomas, bleomycin was found to be useful in the combined treatment with radiation as follows: 1) A minimum required dose for local control of intra-oral carcinomas could be a combination of 30Gy in 3 weeks and 100mg bleomycin during the same period. 2) Although the end results of patients with carcinoma of tongue or floor of mouth have not been improved by this approach, there was marked improvement in patients with carcinoma of the lower gum. 3) For the treatment, the side effect as limiting factor was mucositis, and none of the cases of the series developed pulmonary complication. In the cases controlled by initial combined treatment, no one developed troubles of the mandible, in the follow-up study for the past 10 years. (author)

    The RAdial Velocity Experiment (RAVE) is an ambitious survey to measure the radial velocities, temperatures, surface gravities, metallicities and abundance ratios for up to a million stars using the 1.2-m UK Schmidt Telescope of the Anglo-Australian Observatory (AAO), over the period 2003 - 2011. The survey represents a big advance in our understanding of our own Milky Way galaxy. The main data product will be a southern hemisphere survey of about a million stars. Their selection is based exclusively on their I--band colour, so avoiding any colour-induced bias. RAVE is expected to be the largest spectroscopic survey of the Solar neighbourhood in the coming decade, but with a significant fraction of giant stars reaching out to 10 kpc from the Sun. RAVE offers the first truly representative inventory of stellar radial velocities for all major components of the Galaxy. Here we present the first scientific results of this survey as well as its second data release which doubles the number of previously released ra...

  6. Aquaglyceroporins in the kidney: present state of knowledge and prospects.

    Michalek, K

    2016-04-01

    Aquaporins belong to a family of small, transmembrane proteins that form channels selectively permeable for water. Some of them known as aquaglyceroporins also enable transportation of other small molecules such as glycerol, urea or ammonia. To date, 13 isoforms of aquaporins has been discovered in mammals (AQP0 - AQP12), 9 of which is localized in different parts of the renal tubular epithelium. In recent years, particular interest has been paid to aquaporins selectively permeable only to water molecules, determination of their localization and expression allowed to define the role of these proteins in renal excretion of water and their importance in the development of diseases. Alas, thus far the role in the physiological processes of the aquaglyceroporins localized in the kidneys has not been fully determined. This review summarizes our current knowledge on additional transport functions of renal AQPs (AQP3, AQP6, AQP7 and AQP8). On the basis of the information gathered and the opinions by many authors, it has been found that aquaglyceroporins are most probably the key element in the renal regulation of nitrogen balance and maintenance of the correct pH of body fluids. Elucidating additional transport functions of AQPs in the kidney will improve our understanding of the renal function in heath and diseases. The presented in this article prospect on renal aquaglyceroporin hopefully will stimulate future research in both basic and clinical fields. PMID:27226178

    Full Text Available As was the case at the conference, "Humanities professions in the knowledge society", the Director of Humanities and Philology Studies at the UOC, Isidor Marí, presents this Dossier, and the subsequent virtual debate, with the aim of gaining useful conclusions, with specific repercussions on the organisation of the degree studies and its professional projection, especially at this time, which requires study plans to be redesigned in line with the Bologna process. In the author's opinion, we can only make the right operative decisions when we are able to understand the transformations taking place in the humanistic culture framed by the knowledge society, and to do so, debate has to be opened in which students, graduates, academics, researchers, professionals and analysts can all take part.In this article, Isidor Marí analyses the tensions and contradictions that arise when attempts are made to relate the concepts of the professional world, Humanities and the knowledge society. Firstly, neither are Humanities a profession nor the study of Humanities seen by students or society to be adaptable to the definition of professional profiles. However, this highlights an important paradox, as the culture economy, (and, thus, occupations in the cultural sector, is growing increasingly throughout western societies. Likewise, in terms of the relationship between Humanities and the knowledge society, the author describes and analyses how there currently coexist voices foreseeing the worst alongside those that see information and communications technologies opening the way for an enormously positive transformation in human civilisation and a new cultural era.

    Protein therapeutics are a rapidly growing portion of the pharmaceuticals market and have many significant advantages over traditional small molecule drugs. As this market expands, however, critical regulatory and quality control issues remain, most notably the problem of protein aggregation. Individual target proteins often aggregate into larger masses which trigger an immune response in the body, which can reduce the efficacy of the drug for its intended purpose, or cause serious anaphylactic side-effects. Although detecting and minimizing aggregate formation is critical to ensure an effective product, aggregation dynamics are often highly complicated and there is little hope of reliable prediction and prevention from first principles. This problem is compounded for aggregates in the subvisible range of 100 nm to 10 micrometers where traditional techniques for detecting aggregates have significant limitations. Here, we present an integrated optofluidic platform for detecting nanoscale protein aggregates and characterizing interactions between these aggregates and a reference surface. By delivering light to a solution of proteins with an optical waveguide, scattered light from individual protein aggregates can be detected and analyzed to determine the force profile between each particle and the waveguide surface. Unlike existing methods which only determine size or charge, our label-free screening technique can directly measure the surface interaction forces between single aggregates and the glass substrate. This direct measurement capability may allow for better empirical predictions of the stability of protein aggregates during drug manufacturing and storage.

  13. Hydrothermal systems on Mars: an assessment of present evidence.

    Farmer, J D

    1996-01-01

    Hydrothermal processes have been suggested to explain a number of observations for Mars, including D/H ratios of water extracted from Martian meteorites, as a means for removing CO2 from the Martian atmosphere and sequestering it in the crust as carbonates, and as a possible origin for iron oxide-rich spectral units on the floors of some rifted basins (chasmata). There are numerous examples of Martian channels formed by discharges of subsurface water near potential magmatic heat sources, and hydrothermal processes have also been proposed as a mechanism for aquifer recharge needed to sustain long term erosion of sapping channels. The following geological settings have been identified as targets for ancient hydrothermal systems on Mars: channels located along the margins of impact crater melt sheets and on the slopes of ancient volcanoes; chaotic and fretted terranes where shallow subsurface heat sources are thought to have interacted with ground ice; and the floors of calderas and rifted basins (e.g. chasmata). On Earth, such geological environments are often a locus for hydrothermal mineralization. But we presently lack the mineralogical information needed for a definitive evaluation of hypotheses. A preferred tool for identifying minerals by remote sensing methods on Earth is high spatial resolution, hyperspectral, near-infrared spectroscopy, a technique that has been extensively developed by mineral explorationists. Future efforts to explore Mars for ancient hydrothermal systems would benefit from the application of methods developed by the mining industry to look for similar deposits on Earth. But Earth-based exploration models must be adapted to account for the large differences in the climatic and geological history of Mars. For example, it is likely that the early surface environment of Mars was cool, perhaps consistently below freezing, with the shallow portions of hydrothermal systems being dominated by magma-cryosphere interactions.

  1. Pesticide risk assessment in the United States

    International Nuclear Information System (INIS)

    In recognition of potential risks, all pesticides distributed and sold in the United States must fulfil extensive registration requirements for the Environmental Protection Agency (EPA). Registration is a licensing procedure where industry must submit data to demonstrate the safety of pesticidal substances and products before they can be used commercially. The regulatory control of pesticides is unique among chemicals in the U.S. in that testing beyond initial registration may be imposed by the Agency throughout the commercial life of the chemical, as long as there is adequate justification. Registration requirements are gauged to the nature of potential exposures. For instance, more data are generally needed for food use registrations than for non-food uses because of direct consumption of treated foods by the whole U.S. population. Unlike pesticide practices in many countries and authorities, as in the European Community where agricultural pesticides, non-agricultural pesticides and genetically engineered microbial agents are handled by separate directives, all pesticide activities are covered in the U.S. by the Federal Insecticide, Fungicide and Rodenticide Act. This statute covers pesticide uses on foods and animal feed and a number of non-food applications like forest and horticultural uses, residential lawn care, in-home applications, and disinfectants/sterilants. Traditional inorganic and organic chemicals are covered, as well as biological agents like pheromones. Naturally occurring and genetically altered microorganisms also come under the definition of pesticides, but multicellular animals are exempt from regulation as pesticides. Pesticide registration in the U.S. as in many other countries may be a long-term, resource intensive undertaking. Not uncommonly the process from beginning to complete registration may take 4 to 10 years and cost about $10 million.

  2. Steady state security assessment in deregulated power systems

    Science.gov (United States)

    Manjure, Durgesh Padmakar

    Power system operations are undergoing changes, brought about primarily due to deregulation and subsequent restructuring of the power industry. The primary intention of the introduction of deregulation in power systems was to bring about competition and improved customer focus. The underlying motive was increased economic benefit. Present day power system analysis is much different than what it was earlier, essentially due to the transformation of the power industry from being cost-based to one that is price-based and due to open access of transmission networks to the various market participants. Power is now treated as a commodity and is traded in an open market. The resultant interdependence of the technical criteria and the economic considerations has only accentuated the need for accurate analysis in power systems. The main impetus in security analysis studies is on efficient assessment of the post-contingency status of the system, accuracy being of secondary consideration. In most cases, given the time frame involved, it is not feasible to run a complete AC load flow for determining the post-contingency state of the system. Quite often, it is not warranted as well, as an indication of the state of the system is desired rather than the exact quantification of the various state variables. With the inception of deregulation, transmission networks are subjected to a host of multilateral transactions, which would influence physical system quantities like real power flows, security margins and voltage levels. For efficient asset utilization and maximization of the revenue, more often than not, transmission networks are operated under stressed conditions, close to security limits. Therefore, a quantitative assessment of the extent to which each transaction adversely affects the transmission network is required. This needs to be done accurately as the feasibility of the power transactions and subsequent decisions (execution, curtailment, pricing) would depend upon the

It has ignored aspects of EIA to which agencies funding development have paid little attention--assessing alternatives, monitoring outcomes and enforcing consent conditions. This infers the Fijian state is not serious about using EIA to control environmental quality. Factors other than technical shortcomings are shaping the way the state constrains EIA practice.

    Full Text Available Our research into 52 profiles of the littoral zone of the Macedonian part of Lake Ohrid and numerous samples taken from its surroundings has resulted in a detailed picture of the composition of the Charophyta vegetation in the lake. The results of the research also include data regarding the species composition and present state of Nitella. The dominant species of Nitella is Nitella opaca, which is characterized by a specific distribution, morphological variability and ecology. The present state of Nitella is not steady, especially in the watershed of the lake, since in this area there are some permanent changes in the hydrology of the terrain. Therefore, there is a need to establish long-term and complex monitoring which will result in the prompt detection of risk factors and influences, thereby enabling a rapid reaction to a possible newly emerged negative state.

  2. Initial state report for the safety assessment SR-Can

    International Nuclear Information System (INIS)

    A comprehensive description of the initial state of the engineered parts of the repository system is one of the main bases for the safety assessment. There is no obvious definition of the time of the initial state. For the engineered part of their repository system, the time of deposition is a natural starting point and the initial state in SR-Can is, therefore, defined as the state at the time of deposition for the engineered barrier system. The initial state of the engineered parts of the repository system is largely obtained from the design specifications of the repository, including allowed tolerances or allowance for deviations. Also the manufacturing, excavation and control methods have to be described in order to adequately discuss and handle hypothetical initial states outside the allowed limits in the design specifications. It should also be noted that many parts of the repository system are as yet not finally designed, there can be many changes in the future. The design and technical solutions presented here are representative of the current stage of development. The repository system is based on the KBS-3 method, in which copper canisters with a cast iron insert containing spent nuclear fuel are surrounded by bentonite clay and deposited at 400-700 m depth in saturated granitic rock. The facility design comprises rock caverns, tunnels, deposition positions etc. Deposition tunnels are linked by tunnels for transport and communication and shafts for ventilation. One ramp and five shafts connect the surface facility to the underground repository. The ramp is used for heavy and bulky transports and the shafts are for utility systems and for transport of excavated rock, backfill and staff. For the purposes of the safety assessment, the engineered parts of the repository system have been sub-divided into a number of components or sub-systems.

    A comprehensive description of the initial state of the engineered parts of the repository system is one of the main bases for the safety assessment. There is no obvious definition of the time of the initial state. For the engineered part of their repository system, the time of deposition is a natural starting point and the initial state in SR-Can is, therefore, defined as the state at the time of deposition for the engineered barrier system. The initial state of the engineered parts of the repository system is largely obtained from the design specifications of the repository, including allowed tolerances or allowance for deviations. Also the manufacturing, excavation and control methods have to be described in order to adequately discuss and handle hypothetical initial states outside the allowed limits in the design specifications. It should also be noted that many parts of the repository system are as yet not finally designed, there can be many changes in the future. The design and technical solutions presented here are representative of the current stage of development. The repository system is based on the KBS-3 method, in which copper canisters with a cast iron insert containing spent nuclear fuel are surrounded by bentonite clay and deposited at 400-700 m depth in saturated granitic rock. The facility design comprises rock caverns, tunnels, deposition positions etc. Deposition tunnels are linked by tunnels for transport and communication and shafts for ventilation. One ramp and five shafts connect the surface facility to the underground repository. The ramp is used for heavy and bulky transports and the shafts are for utility systems and for transport of excavated rock, backfill and staff. For the purposes of the safety assessment, the engineered parts of the repository system have been sub-divided into a number of components or sub-systems. These are: The fuel, (also including cavities in the canister since strong interactions between the two occur if the

    2014-06-01

    Northeast India is one of the most highly seismically active regions in the world with more than seven earthquakes on an average per year of magnitude 5.0 and above. Reliable seismic hazard assessment could provide the necessary design inputs for earthquake resistant design of structures in this region. In this study, deterministic as well as probabilistic methods have been attempted for seismic hazard assessment of Tripura and Mizoram states at bedrock level condition. An updated earthquake catalogue was collected from various national and international seismological agencies for the period from 1731 to 2011. The homogenization, declustering and data completeness analysis of events have been carried out before hazard evaluation. Seismicity parameters have been estimated using G–R relationship for each source zone. Based on the seismicity, tectonic features and fault rupture mechanism, this region was divided into six major subzones. Region specific correlations were used for magnitude conversion for homogenization of earthquake size. Ground motion equations (Atkinson and Boore 2003; Gupta 2010) were validated with the observed PGA (peak ground acceleration) values before use in the hazard evaluation. In this study, the hazard is estimated using linear sources, identified in and around the study area. Results are presented in the form of PGA using both DSHA (deterministic seismic hazard analysis) and PSHA (probabilistic seismic hazard analysis) with 2 and 10% probability of exceedance in 50 years, and spectral acceleration (T = 0.2 s, 1.0 s) for both the states (2% probability of exceedance in 50 years). The results are important to provide inputs for planning risk reduction strategies, for developing risk acceptance criteria and financial analysis for possible damages in the study area with a comprehensive analysis and higher resolution hazard mapping.

    regionalized cluster-based water isotope prediction model (RCWIP) which uses fuzzy clustering to delineate regions of climatic similarity, and to determine regionalized regression models for each climatic cluster in order to lower prediction uncertainty of isotope values. Here, we present new data and figures on the spatial and temporal evolution of the GNIP network, including station spatial density and coverage analysis. Moreover, we assess outstanding deficits in the spatial coverage of the GNIP network by applying the clustering structure of the RCWIP approach to identify those regions which would benefit most from an improved GNIP sampling. Finally, we present an updated global meteoric water (GMWL) line based on different calculation methods (ordinary least squares method, weighted least squares, or based on weighted means).

    The capital intensive nature of clean energy technologies suggests that manufacturing clean energy equipment has the potential to support state and local economic development efforts. However, manufacturing siting decisions tend to be complex and multi-variable decision processes that require in-depth knowledge of specific markets, the logistical requirements of a given technology, and insight into global clean tech trends. This presentation highlights the potential of manufacturing in supporting economic development opportunities while also providing examples of the financial considerations affecting manufacturing facility siting decisions for wind turbine blades and solar PV. The presentation also includes discussion of other more qualitative drivers of facility siting decisions as gleaned from NREL industry interviews and discusses strategies state and local policymakers may employee to bolster their chances of successfully attracting clean energy manufacturers to their localities.

    2015-04-01

    The Chiapas State, in southeastern Mexico, is a very active seismic region due to the interaction of three tectonic plates: Northamerica, Cocos and Caribe. We present a probabilistic seismic hazard assessment (PSHA) specifically performed to evaluate seismic hazard in the Chiapas state. The PSHA was based on a composited seismic catalogue homogenized to Mw and was used a logic tree procedure for the consideration of different seismogenic source models and ground motion prediction equations (GMPEs). The results were obtained in terms of peak ground acceleration as well as spectral accelerations. The earthquake catalogue was compiled from the International Seismological Center and the Servicio Sismológico Nacional de México sources. Two different seismogenic source zones (SSZ) models were devised based on a revision of the tectonics of the region and the available geomorphological and geological maps. The SSZ were finally defined by the analysis of geophysical data, resulting two main different SSZ models. The Gutenberg-Richter parameters for each SSZ were calculated from the declustered and homogenized catalogue, while the maximum expected earthquake was assessed from both the catalogue and geological criteria. Several worldwide and regional GMPEs for subduction and crustal zones were revised. For each SSZ model we considered four possible combinations of GMPEs. Finally, hazard was calculated in terms of PGA and SA for 500-, 1000-, and 2500-years return periods for each branch of the logic tree using the CRISIS2007 software. The final hazard maps represent the mean values obtained from the two seismogenic and four attenuation models considered in the logic tree. For the three return periods analyzed, the maps locate the most hazardous areas in the Chiapas Central Pacific Zone, the Pacific Coastal Plain and in the Motagua and Polochic Fault Zone; intermediate hazard values in the Chiapas Batholith Zone and in the Strike-Slip Faults Province. The hazard decreases

  18. Emerging contaminants: Presentations at the 2009 Toxicology and Risk Assessment Conference

    International Nuclear Information System (INIS)

    A session entitled 'Emerging Contaminants' was held in April 2009 in Cincinnati, OH at the 2009 Toxicology and Risk Assessment Conference. The purpose of the session was to share information on both programmatic and technical aspects associated with emerging contaminants. Emerging contaminants are chemicals or materials that are characterized by a perceived or real threat to human health or environment, a lack of published health standards or an evolving standard. A contaminant may also be 'emerging' because of the discovery of a new source, a new pathway to humans, or a new detection method or technology. The session included five speakers representing the Department of Defense (DoD), the Environmental Protection Agency (EPA), and each of the military services. The DoD created the Emerging Contaminant Directorate to proactively address environmental, health, and safety concerns associated with emerging contaminants. This session described the scan-watch-action list process, impact assessment methodology, and integrated risk management concept that DoD has implemented to manage emerging contaminants. EPA presented emerging trends in health risk assessment. Researchers made technical presentations on the status of some emerging contaminates in the assessment process (i.e. manganese, RDX, and naphthalene).

  20. Formulation and Presentation of Risk Assessments to Address Risk Targets for Radioactive Waste Disposal

    International Nuclear Information System (INIS)

    The Swedish regulators have been active in the field of performance assessment of radioactive waste disposal facilities for many years and have developed sophisticated approaches to the development of scenarios and other aspects of assessments. These assessments have generally used dose as the assessment end-point. Regulations recently established in Sweden (SSI FS 1998:1) have introduced a risk criterion for radioactive waste disposal: the annual risk of harmful effects after closure of a disposal facility should not exceed 10-6 for a representative individual in the group exposed to the greatest risk. This report evaluates different approaches to the definition and use of probabilities in the context of risk assessments, and examines the presentation of the results of risk assessments in safety cases to meet risk targets. The report illustrates the strengths and weaknesses of different possible approaches to risk assessment by reference to assessments in other countries, and provides suggestions for future activity and development in this area by the Swedish regulators. The review of experience in other countries has led to a number of key observations relevant to the conduct of regulatory work on risk assessments and preparations for review. These highlight the importance of developing a protocol for conducting calculations, and linking such a protocol to the requirements of risk assessment calculations and to existing code and model capabilities. There are a number of decisions and assumptions required in developing a risk assessment methodology that could potentially affect the calculated results. These assumptions are independent of the analysis of performance, and relate to issues such as the expectation value of risk, risk dilution, the definition of probability density functions and achieving convergence. A review of a proponent's risk assessment should address these issues in determining the appropriateness and validity of the results presented

  4. Development of Risk Assessment Methodology for State's Nuclear Security Regime

    International Nuclear Information System (INIS)

    Threats of nuclear terrorism are increasing after 9/11 terrorist attack. Treats include nuclear explosive device (NED) made by terrorist groups, radiological damage caused by a sabotage aiming nuclear facilities, and radiological dispersion device (RDD), which is also called 'dirty bomb'. In 9/11, Al Qaeda planed to cause radiological consequences by the crash of a nuclear power plant and the captured airplane. The evidence of a dirty bomb experiment was found in Afganistan by the UK intelligence agency. Thus, the international communities including the IAEA work substantial efforts. The leaders of 47 nations attended the 2010 nuclear security summit hosted by President Obama, while the next global nuclear summit will be held in Seoul, 2012. Most states established and are maintaining state's nuclear security regime because of the increasing threat and the international obligations. However, each state's nuclear security regime is different and depends on the state's environment. The methodology for the assessment of state's nuclear security regime is necessary to design and implement an efficient nuclear security regime, and to figure out weak points. The IAEA's INPRO project suggests a checklist method for State's nuclear security regime. The IAEA is now researching more quantitative methods cooperatively with several countries including Korea. In this abstract, methodologies to evaluate state's nuclear security regime by risk assessment are addressed

    In 1990, the lipid nanoparticles were invented in the laboratories, the first patent filings took place in 1991. The lipid nanoparticles were developed as alternative to traditional carriers such as polymeric nanoparticles and liposomes. After 20 years of lipid nanoparticles, the present state of development is reviewed - academic progress but also the development state of pharmaceutical products for the benefit of patients. Meanwhile many research groups are active worldwide, their results are reviewed which cover many different administration routes: dermal and mucosal, oral, intravenous/parenteral, pulmonary but also ocular. The lipid nanoparticles are also used for peptide/protein delivery, in gene therapy and various miscellaneous applications (e.g. vaccines). The questions of large scale production ability, accepted regulatory status of excipients, and - important for the public perception - lack of nanotoxicity are discussed, important pre-requisites for the use of each nanocarrier in products. Identical to the liposomes, the lipid nanoparticles entered first the cosmetic market, product examples are presented. Presently the pharmaceutical product development focuses on products for unmet needs and on niche products with lower development costs (e.g. ocular delivery), which can be realized also by smaller companies. A pharmaceutical perspective for the future is given, but also outlined the opportunities for non-pharmaceutical use, e.g. in nutraceuticals. PMID:21291409

    Rhodopsin, the light-sensing molecule in the outer segments of rod photoreceptors, is responsible for converting light into neuronal signals in a process known as phototransduction. Rhodopsin is thus a functional biomarker for rod photoreceptors. We developed a novel technology based on visible-light optical coherence tomography (VIS-OCT) for in vivo molecular imaging of rhodopsin. The depth resolution of OCT allows the visualization of the location where the change of optical absorption occurs and provides a potentially accurate assessment of rhodopsin content by segmentation of the image at the location. A broadband supercontinuum laser, whose filtered output was centered at 520 nm, was used as the illuminating light source. To test the capabilities of the system on rhodopsin mapping we imaged the retina of albino rats. The rats were dark adapted before imaging. An integrated near infrared OCT was used to guide the alignment in dark. VIS-OCT three-dimensional images were then acquired under dark- and light- adapted states sequentially. Rhodopsin distribution was calculated from the differential image. The rhodopsin distributions can be displayed in both en face view and depth-resolved cross-sectional image. Rhodopsin OCT can be used to quantitatively image rhodopsin distribution and thus assess the distribution of functional rod photoreceptors in the retina. Rhodopsin OCT can bring significant impact into ophthalmic clinics by providing a tool for the diagnosis and severity assessment of a variety of retinal conditions.

    2011-01-01

    The Earth, like other planets with a relatively thick atmosphere, is not locally in radiative equilibrium and the transport of energy by the geophysical fluids (atmosphere and ocean) plays a fundamental role in determining its climate. Using simple energy-balance models, it was suggested a few decades ago that the meridional energy fluxes might follow a thermodynamic Maximum Entropy Production (MEP) principle. In the present study, we assess the MEP hypothesis in the framework of a minimal climate model based solely on a robust radiative scheme and the MEP principle, with no extra assumptions. Specifically, we show that by choosing an adequate radiative exchange formulation, the Net Exchange Formulation, a rigorous derivation of all the physical parameters can be performed. The MEP principle is also extended to surface energy fluxes, in addition to meridional energy fluxes. The climate model presented here is extremely fast, needs very little empirical data and does not rely on ad hoc parameterizations. We in...

    At the present time, it is nearly impossible to treat pediatric functional gastrointestinal disorders associated with pain in an evidence based fashion. This is due to the overall lack of controlled studies and, even more importantly, the complexity of the contributors to disease phenotype which are not controlled or accounted for in most therapeutic trials. In this manuscript, we review the challenges of defining entry criteria, controlling for the large number of biopsychosocial factors which may effect outcomes, and understanding pharmacokinetic and pharmacodynamic factors when designing therapeutic trials for abdominal pain in children. We also review the current state of pediatric abdominal pain therapeutics and discuss trial design considerations as we move forward.

  10. Towards intraoperative assessment of tumor margins in breast surgery using optical coherence elastography (Conference Presentation)

    Surgical excision of tumor is a critical factor in the management of breast cancer. The most common surgical procedure is breast-conserving surgery. The surgeon's goal is to remove the tumor and a rim of healthy tissue surrounding the tumor: the surgical margin. A major issue in breast-conserving surgery is the absence of a reliable tool to guide the surgeon in intraoperatively assessing the margin. A number of techniques have been proposed; however, the re-excision rate remains high and has been reported to be in the range 30-60%. New tools are needed to address this issue. Optical coherence elastography (OCE) shows promise as a tool for intraoperative tumor margin assessment in breast-conserving surgery. Further advances towards clinical translation are limited by long scan times and small fields of view. In particular, scanning over sufficient areas to assess the entire margin in an intraoperative timeframe has not been shown to be feasible. Here, we present a protocol allowing ~75% of the surgical margins to be assessed within 30 minutes. To achieve this, we have incorporated a 65 mm-diameter (internal), wide-aperture annular piezoelectric transducer, allowing the entire surface of the excised tumor mass to be automatically imaged in an OCT mosaic comprised of 10 × 10 mm tiles. As OCT is effective in identifying adipose tissue, our protocol uses the wide-field OCT to selectively guide subsequent local OCE scanning to regions of solid tissue which often present low contrast in OCT images. We present promising examples from freshly excised human breast tissue.

    The human memory is a complex cognitive system whose close relationship with executive functions implies that, in many occasions, a mnemonic deficit comprises difficulties to operate with correctly stored contents. Traditional memory tests, more focused in the information storage than in its processing, may be poorly sensitive both to subjects' daily life functioning and to changes originated by rehabilitation programs. In memory assessment, there is plenty evidence with regards to the need of improving it by means of tests which offer a higher ecological validity, with information that may be presented in various sensorial modalities and produced in a simultaneous way. Virtual reality reproduces three-dimensional environments with which the patient interacts in a dynamic way, with a sense of immersion in the environment similar to the presence and exposure to a real environment, and in which presentation of such stimuli, distractors and other variables may be systematically controlled. The current review aims to go deeply into the trajectory of neuropsychological assessment of memory based in virtual reality environments, making a tour through existing tests designed for assessing learning, prospective, episodic and spatial memory, as well as the most recent attempts to perform a comprehensive evaluation of all memory components.

Recent advances in molecular biology, immunology, and development of robust production platforms will drive the development of more MAb's suitable to treat an ever increasing number of disease states. This circumstance combined with the fact that many of the original antibody therapies from the 1980 s and 1990 s will soon be coming off patent will attract a great deal of investment in the development of larger industrial facilities to increase monoclonal antibody to meet increasing demand. In this review, the present state of the science that underlies the development of new antibodies therapies in Chinese hamster ovary cells combined with a description of the present challenges facing the industry in terms of the limitations of output and compliance with current good manufacturing practices and FDA regulations. Also addressed are future challenges to overcome production bottlenecks, description of critical quality control attributes particular to antibodies, and detailed treatment of scale-up considerations.

    The practical development of quantum plasmonic circuits incorporating non-classical interference [1] and sources of entangled states calls for a versatile quantum theoretical framework which can fully describe the generation and detection of entangled photons and plasmons. However, majority of the presently used theoretical approaches are typically limited to the toy models assuming loss-less and nondispersive elements or including just a few resonant modes. Here, we present a rigorous Green function approach describing entangled photon-plasmon state generation through spontaneous wave mixing in realistic metal-dielectric nanostructures. Our approach is based on the local Huttner-Barnett quantization scheme [2], which enables problem formulation in terms of a Hermitian Hamiltonian where the losses and dispersion are fully encoded in the electromagnetic Green functions. Hence, the problem can be addressed by the standard quantum mechanical perturbation theory, overcoming mathematical difficulties associated with other quantization schemes. We derive explicit expressions with clear physical meaning for the spatially dependent two-photon detection probability, single-photon detection probability and single-photon density matrix. In the limiting case of low-loss nondispersive waveguides our approach reproduces the previous results [3,4]. Importantly, our technique is far more general and can quantitatively describe generation and detection of spatially-entangled photons in arbitrary metal-dielectric structures taking into account actual losses and dispersion. This is essential to perform the design and optimization of plasmonic structures for generation and control of quantum entangled states. [1] J.S. Fakonas, H. Lee, Y.A. Kelaita and H.A.

    Louis Pasteur described the first measurements of airborne microorganisms in 1861. A century later, the inhalation of spores from thermophilic microorganisms was shown to induce attacks of farmers' lung in patients with this disease, while endotoxins originating from Gram-negative bacteria were identified as causal agents for byssinosis in cotton workers. Further epidemiological and toxicological studies have demonstrated inflammatory, respiratory, and pathogenic effects following exposure to bioaerosols. Exposure assessment is often confounded by the diversity of bioaerosol agents in the environment. Microorganisms represent a highly diverse group that may vary in toxicity. Fungi and bacteria are mainly quantified as broad groups using a variety of viable and nonviable assessment methods. Endotoxins and β(1 → 3)-glucans are mainly measured by their activity in the Limulus amebocyte lysate assay, enzymes by immuno-chemical methods and mycotoxins by liquid chromatography-mass spectrometry. Few health-based occupational exposure limits (OELs) are available for risk assessment. For endotoxins, a health-based OEL of 90 endotoxin units m(-3) has been proposed in the Netherlands. A criteria document for fungal spores recently proposed a lowest observed effect level of 100,000 spores m(-3) for non-pathogenic and non-mycotoxin producing species based on inflammatory respiratory effects. Recent developments in bioaerosol assessment were presented at the Organic Dust Tromsø Symposium including molecular biological methods for infectious agents and organisms that are difficult to cultivate; studies of submicronic and hyphal fragments from fungi; the effect of biodiversity of microorganisms in asthma studies; and new/improved measurement methods for fungal antigens, enzymes and allergens. Although exposure assessment of bioaerosol agents is complex and limited by the availability of methods and criteria, the field is rapidly evolving. PMID:22267210

  17. A state-impact-state methodology for assessing environmental impact in land use planning

    International Nuclear Information System (INIS)

    The implementation of land use planning (LUP) has a large impact on environmental quality. There lacks a widely accepted and consolidated approach to assess the LUP environmental impact using Strategic Environmental Assessment (SEA). In this paper, we developed a state-impact-state (SIS) model employed in the LUP environmental impact assessment (LUPEA). With the usage of Matter-element (ME) and Extenics method, the methodology based on the SIS model was established and applied in the LUPEA of Zoucheng County, China. The results show that: (1) this methodology provides an intuitive and easy understanding logical model for both the theoretical analysis and application of LUPEA; (2) the spatial multi-temporal assessment from base year, near-future year to planning target year suggests the positive impact on the environmental quality in the whole County despite certain environmental degradation in some towns; (3) besides the spatial assessment, other achievements including the environmental elements influenced by land use and their weights, the identification of key indicators in LUPEA, and the appropriate environmental mitigation measures were obtained; and (4) this methodology can be used to achieve multi-temporal assessment of LUP environmental impact of County or Town level in other areas. - Highlights: • A State-Impact-State model for Land Use Planning Environmental Assessment (LUPEA). • Matter-element (ME) and Extenics methods were embedded in the LUPEA. • The model was applied to the LUPEA of Zoucheng County. • The assessment shows improving environment quality since 2000 in Zoucheng County. • The method provides a useful tool for the LUPEA in the county level

    Regardless of cost and performance some wind projects are unable to proceed to commissioning as a result of deployment barriers. Principal deployment barriers in the industry today include: wildlife, public acceptance, access to transmission, and radar. To date, methods for understanding these non-technical barriers have failed to accurately characterize the costs imposed by deployment barriers and the degree of impact to the industry. Analytical challenges include limited data and modeling capabilities. Changes in policy and regulation, among other factors, also add complexity to analysis of impacts from deployment barriers. This presentation details preliminary results from new NREL analysis focused on quantifying the impact of deployment barriers on the wind resource of the United States, the installed cost of wind projects, and the total electric power system cost of a 20% wind energy future. In terms of impacts to wind project costs and developable land, preliminary findings suggest that deployment barriers are secondary to market drivers such as demand. Nevertheless, impacts to wind project costs are on the order of $100/kW and a substantial share of the potentially developable windy land in the United States is indeed affected by deployment barriers.

  20. Present state of JAERI National Data Center (NDC) for CTBT verification

    International Nuclear Information System (INIS)

    The Japan Atomic Energy Research Institute (JAERI) has developed the National Data Center (NDC) for radionuclide as part of the international monitoring regime related to the Comprehensive Nuclear-Test-Ban Treaty (CTBT). JAERI NDC already started to input gamma-ray spectrum data obtained from several International Monitoring System (IMS) stations into a database. Data analysis reports made by the International Data Center (IDC) are also stored in the database. Some software tools are under development for the NDC's independent analysis such as investigation of existence of the radionuclides derived from nuclear explosion and presumptive analysis of source location of radionuclide release. The NDC system will also be able to post IMS data and analysis results to the authorized users on the Internet. This paper presents the role, current state of system development and future plan of JAERI NDC. (author)

  1. Groundwater governance in Asia: present state and barriers to implementation of good governance

    Science.gov (United States)

    Tanaka, T.

    2014-09-01

    The present state of groundwater governance in Asia was reviewed. The main problem regarding groundwater resources in each Asian country is overexploitation, causing water level decline, land subsidence and salt water intrusion. For those groundwater hazards, many countries have established regulations such as laws and regulations as countermeasures. However, those laws and regulations are not the basic laws on groundwater resources, but only for countermeasures to prevent groundwater hazards. Common problems and barriers for implementing groundwater governance in Asian countries are that there is more than one institute with different and sometimes overlapping responsibilities in groundwater management. To overcome those conflicts among institutions and establishment of good governance, it is necessary to establish an agency in the government as one coordinate function reinforcing the direct coordination and facilitation of groundwater policy-making and management. As one such framework, the conceptual law called the Water Cycle Basic Law, which is under planning in Japan, is examined in this paper.

  2. The present state and the future of nuclear power development in the world

    Some studies have indicated that the capacity of self-assessment of affective state is more compromised during mania than during depression. In the present study, we investigated whether the reliability of self-assessment in bipolar disorder varies as a function of actual affective state (i.e., euthymia, mania, or depression). Sixty-five patients with a diagnosis of type I and type II bipolar disorder were evaluated with regard to the occurrence of an affective syndrome using the Clinical Global Impressions Scale for use in bipolar illness, the Positive and Negative Syndrome Scale, and the Global Assessment of Functioning scale. In parallel, we applied the Analog Visual Mood Scale, a self-assessment tool to evaluate mood changes. The same individual prospectively completed the self-assessment scale in different affective states. During depression, the patients' evaluation was significantly different from when they were in manic or euthymic mood states. However, when in mania, the patients evaluated their mood state similarly to when they were euthymic. The bipolar patients in mania but not in depression did not reliably evaluate themselves with regard to their affective state. PMID:24727726

    Heath, G.

    2014-04-01

    Natural gas (NG) is a potential "bridge fuel" during transition to a decarbonized energy system: It emits less carbon dioxide during combustion than other fossil fuels and can be used in many industries. However, because of the high global warming potential of methane (CH4, the major component of NG), climate benefits from NG use depend on system leakage rates. Some recent estimates of leakage have challenged the benefits of switching from coal to NG, a large near-term greenhouse gas (GHG) reduction opportunity. During this presentation, Garvin will review evidence from multiple perspectives - life cycle assessments (LCAs), inventories and measurements - about NG leakage in the US. Particular attention will be paid to a recent article in Science magazine which reviewed over 20 years of published measurements to better understand what we know about total methane emissions and those from the oil and gas sectors. Scientific and policy implications of the state of knowledge will be discussed.

    Full Text Available National parks in the United States are protected areas wherein the natural habitat is to be conserved for future generations. Deposition of anthropogenic nitrogen (N transported from areas of human activity (fuel combustion, agriculture may affect these natural habitats if it exceeds an ecosystem-dependent critical load (CL. We quantify and interpret the deposition to Class I US national parks for present-day and future (2050 conditions using the GEOS-Chem global chemical transport model with 1/2° × 2/3° horizontal resolution over North America. We estimate CL values in the range 2.5–5 kg N ha−1 yr−1 for the different parks with the goal of protecting the most sensitive ecosystem receptors. For present-day conditions, we find 24 out of 45 parks to be in CL exceedance and 14 more to be marginally so. Many of these are in remote areas of the West. Most (40–85% of the deposition originates from NOx emissions (fuel combustion. We then project future changes in N deposition using the Representative Concentration Pathway (RCP emission scenarios for 2050. These feature 52–73% declines in US NOx emissions relative to present but 19–50% increases in US ammonia (NH3 emissions. Nitrogen deposition at US national parks then becomes dominated by domestic NH3 emissions. While deposition decreases in the East relative to present, there is little progress in the West and increases in some regions. We find that 17–25 US national parks will have CL exceedances in 2050 based on the RCP scenarios. Even in total absence of anthropogenic NOx emissions, 14–18 parks would still have a CL exceedance. Returning all parks to N deposition below CL by 2050 will require at least a 55% decrease in anthropogenic NH3 emissions relative to RCP-projected 2050 levels.

  10. Carbonate mineral saturation states in the East China Sea: present conditions and future scenarios

    Directory of Open Access Journals (Sweden)

    W.-C. Chou

    2013-10-01

    Full Text Available To assess the impact of rising atmospheric CO2 and eutrophication on the carbonate chemistry of the East China Sea shelf waters, saturation states (Ω for two important biologically relevant carbonate minerals – calcite (Ωc and aragonite (Ωa – were calculated throughout the water column from dissolved inorganic carbon (DIC and total alkalinity (TA data collected in spring and summer of 2009. Results show that the highest Ωc (∼9.0 and Ωa (∼5.8 values were found in surface water of the Changjiang plume area in summer, whereas the lowest values (Ωc = ∼2.7 and Ωa = ∼1.7 were concurrently observed in the bottom water of the same area. This divergent behavior of saturation states in surface and bottom waters was driven by intensive biological production and strong stratification of the water column. The high rate of phytoplankton production, stimulated by the enormous nutrient discharge from the Changjiang, acts to decrease the ratio of DIC to TA, and thereby increases Ω values. In contrast, remineralization of organic matter in the bottom water acts to increase the DIC to TA ratio, and thus decreases Ω values. The projected result shows that continued increases of atmospheric CO2 under the IS92a emission scenario will decrease Ω values by 40–50% by the end of this century, but both the surface and bottom waters will remain supersaturated with respect to calcite and aragonite. Nevertheless, superimposed on such Ω decrease is the increasing eutrophication, which would mitigate or enhance the Ω decline caused by anthropogenic CO2 uptake in surface and bottom waters, respectively. Our simulation reveals that, under the combined impact of eutrophication and augmentation of atmospheric CO2, the bottom water of the Changjiang plume area will become undersaturated with respect to aragonite (Ωa = ∼0.8 by the end of this century, which would threaten the health of the benthic ecosystem.

  11. Present state and problems of the measures for securing stable supply of uranium resources

    International Nuclear Information System (INIS)

    The long-term stable supply of uranium resources must be secured in order to accelerate the development and utilization of nuclear power in Japan. All uranium required in Japan is imported from foreign countries, and depends on small number of suppliers. On the use of uranium, various restrictions have been imposed by bilateral agreements from the viewpoint of nuclear non-proliferation policy. At present, the demand-supply relation in uranium market is not stringent, but in the latter half of 1980s, it is feared that it will be stringent. The prospect of the demand and supply of uranium resources, the state of securing uranium resources, the present policy on uranium resources, the necessity of establishing the new policy, and the active promotion of uranium resource measures are described. The measures to be taken are the promotion of exploration and development of mines, the participation in the management of such foreign projects, the promotion of diversifying the supply sources, the establishment of the structure to accept uranium resources, the promotion of the storage of uranium, and the rearrangement of general coordination and promotion functions for uranium resource procurement.

    Galabov, Vasko

    2015-01-01

    In this paper we present a study of the present state of the Black Sea wave energy. The studies of other authors are based on the use of input data from atmospheric reanalysis or a downscaling of such reanalysis. Instead of reanalysis data, we use input data from the operational limited area numerical weather prediction model ALADIN. We showed that the estimations of the Black Sea wave energy based on reanalyses deviate significantly from the real potential. We showed also that the highest values of the mean annual wave power flux is between 4.5 and 5.0 kW/m2 and the near shore areas with the highest wave energy potential are the southernmost Bulgarian coast and the coast of Turkey north of Istanbul. While we showed that the wind data from the reanalysis are not useful for the estimation of the actual wave energy potential, we claimed that the reanalysis data is useful to study the long term changes of the wave energy of the Black Sea. We used the 10m winds from the recent ERA-20C reanalysis, which covers the...

    1979-01-01

    The geothermal resource assessment presented is a refinement and updating of USGS Circular 726. Nonproprietary information available in June 1978 is used to assess geothermal energy in the ground and, when possible, to evaluate the fraction that might be recovered at the surface. Five categories of geothermal energy are discussed: conduction-dominated regimes, igneous-related geothermal systems, high-temperature (> 150/sup 0/C) and intermediate-temperature (90 to 150/sup 0/C) hydrothermal convection systems, low-temperature (< 90/sup 0/C) geothermal waters, and geopressured-geothermal energy (both thermal energy and energy from dissolved methane). Assessment data are presented on three colored maps prepared in cooperation with the National Oceanic and Atmospheric Administration. Separate abstracts were prepared for papers on these five categories.

  14. Seismic hazard assessment of the Hanford region, Eastern Washington State

    International Nuclear Information System (INIS)

    A probabilistic seismic hazard assessment was made for a site within the Hanford region of eastern Washington state, which is characterized as an intraplate region having a relatively low rate of seismic activity. Probabilistic procedures, such as logic trees, were utilized to account for the uncertainties in identifying and characterizing the potential seismic sources in the region. Logic trees provide a convenient, flexible means of assessing the values and relative likelihoods of input parameters to the hazard model that may be dependent upon each other. Uncertainties accounted for in this way include the tectonic model, segmentation, capability, fault geometry, maximum earthquake magnitude, and earthquake recurrence rate. The computed hazard results are expressed as a distribution from which confidence levels are assessed. Analysis of the results show the contributions to the total hazard from various seismic sources and due to various earthquake magnitudes. In addition, the contributions of uncertainties in the various source parameters to the uncertainty in the computed hazard are assessed. For this study, the major contribution to uncertainty in the computed hazard are due to uncertainties in the applicable tectonic model and the earthquake recurrence rate. This analysis serves to illustrate some of the probabilistic tools that are available for conducting seismic hazard assessments and for analyzing the results of these studies. 5 references, 7 figures

    Asthma affects hundreds of millions of people worldwide, and the prevalence of the disease appears to be increasing. One of the most important aspects of asthma is the excessive bronchoconstriction that results in many of the symptoms experienced by asthma sufferers, but the relationship between bronchoconstriction and airway morphology is not clearly established. We present the imaging results of a study involving a segmental allergen challenge given to both allergic asthmatic (n = 12) and allergic non-asthmatic (n = 19) human volunteers. Using OCT, we have imaged and assessed baseline morphology in a right upper lobe (RUL) airway, serving as the control, and a right middle lobe (RML) airway, in which the allergen was to be administered. After a period of 24 hours had elapsed following the administration of the allergen, both airways were again imaged and the response morphology assessed. A number of airway parameters were measured and compared, including epithelial thickness, mucosal thickness and buckling, lumen area, and mucus content. We found that at baseline epithelial thickness, mucosal thickness, and mucosal buckling were greater in AAs than ANAs. We also observed statistically significant increases in these values 24 hours after the allergen had been administered for both the ANA and AA sets. In comparison, the control airway which received a diluent showed no statistically significant change.

    2015-10-01

    Full Text Available Development of the comprehensive care plan (CCP is a requirement for nursing homes participating in the federal Medicare and Medicaid programs, referred to as skilled nursing facilities. The plan must be developed within the context of the comprehensive interdisciplinary assessment framework—the Resident Assessment Instrument (RAI. Consistent compliance with this requirement has been difficult to achieve. To improve the quality of CCP development within this framework, an increased understanding of complex factors contributing to inconsistent compliance is required. In this commentary, we examine the history of the comprehensive care plan; its development within the RAI framework; linkages between the RAI and registered nurse staffing; empirical evidence of the CCP’s efficacy; and the limitations of extant standards of practices in CCP development. Because of the registered nurse’s educational preparation, professional practice standards, and licensure obligations, the essential contributions of professional nurses in CCP development are emphasized. Recommendations for evidence-based micro and macro level practice changes with the potential to improve the quality of CCP development and regulatory compliance are presented. Suggestions for future research are given.

  20. Present status of alpha-particle condensate states in self-conjugate 4n nuclei

    International Nuclear Information System (INIS)

    Low density states near the 3α and 4α breakup threshold in 12C and 16O, respectively, are discussed in terms of the α-particle condensation. Calculations are performed in OCM (Orthogonality Condition Model) and THSR (Tohsaki-Horiuchi-Schuck-Roepke) approaches. The 02+ state in 12C and the 06+ state in 16C are shown to have dilute density structures and give strong enhancement of the occupation of the S-state c.o.m. orbital of the α-particles. The 06+ state in 16C has a large component of α + 12C(02+) configuration, which is another reliable evidence of the state to be of 4α condensate nature. The possibility of the existence of α-particle condensed states in heavier nα nuclei is also discussed. (author)

    Full Text Available Abstract Background Few studies exist on the validity of food frequency questionnaires (FFQs administered to elderly people. The aim of this study was to assess the validity of a short FFQ on present dietary intake, developed specially for the AGES-Reykjavik Study, which includes 5,764 elderly individuals. Assessing the validity of FFQs is essential before they are used in studies on diet-related disease risk and health outcomes. Method 128 healthy elderly participants (74 y ± 5.7; 58.6% female answered the AGES-FFQ, and subsequently filled out a 3-day weighed food record. Validity of the AGES-FFQ was assessed by comparing its answers to the dietary data obtained from the weighed food records, using Spearman's rank correlation, Chi-Square/Kendall's tau, and a Jonckheere-Terpstra test for trend. Result For men a correlation ≥ 0.4 was found for potatoes, fresh fruits, oatmeal/muesli, cakes/cookies, candy, dairy products, milk, pure fruit juice, cod liver oil, coffee, tea and sugar in coffee/tea (r = 0.40-0.71. A lower, but acceptable, correlation was also found for raw vegetables (r = 0.33. The highest correlation for women was found for consumption of rye bread, oatmeal/muesli, raw vegetables, candy, dairy products, milk, pure fruit juice, cod liver oil, coffee and tea (r = 0.40-0.61. An acceptable correlation was also found for fish topping/salad, fresh fruit, blood/liver sausage, whole-wheat bread, and sugar in coffee/tea (r = 0.28-0.37. Questions on meat/fish meals, cooked vegetables and soft drinks did not show a significant correlation to the reference method. Pearson Chi-Square and Kendall's tau showed similar results, as did the Jonckheere-Terpstra trend test. Conclusion A majority of the questions in the AGES-FFQ had an acceptable correlation and may be used to rank individuals according to their level of intake of several important foods/food groups. The AGES-FFQ on present diet may therefore be used to study the relationship between

  2. Present state and prospects of using monocrystals at relativistic particle accelerators

    International Nuclear Information System (INIS)

    The present state and prospects of producing quasimonochromatic linearly-polarized high-energy photon beams in electron-positron interactions with monocrystals are described. Experiments performed on the Kharkov linear accelerator showed a sharp decrease in the positron radiation intensity as compared with electron intensity depending on the silicon crystal orientation. Data about the effect of the positrons and electrons moving parallel to the silicon monocrystal axis proved that an increase in thermal variations of lattice atoms results in a still greater suppression of positron radiation and in a rise in radiation of electrons. The intensity of channeling positron radiation in the range of photon energies from 0.3 to 0.8 MeV exceeds the radiation intensity in a disoriented crystal. Experiments on 1 GeV positrons showed a decrease in multiple scattering. It is shown that in devising accelerating structures the monocrystals can be used to produce beams with a limiting current density and to form high-energy beams

    Although an estimated 6.5 million United States (US) children aged 6-17 practiced a martial art in 2004, there have been no nationally representative studies comparing pediatric injuries among the three most popular disciplines, karate, taekwondo, and judo. Describe pediatric martial arts injuries presenting to a representative sample of US Emergency Departments (EDs) from 1990 to 2003. We reviewed all martial arts injuries captured by the US Consumer Product Safety Commission's (CPSC), National Electronic Injury Surveillance System (NEISS). An estimated 128,400 children mechanism of injury was being kicked (25.6%), followed by falling (20.6%) and kicking (18.0%). The majority of injuries occurred to the lower leg/foot/ankle (30.1%) and hand/wrist (24.5%). The most common injury diagnoses were sprains/strains (29.3%), contusions/abrasions (27.8%), and fractures (24.6%). Participants in judo sustained significantly higher proportions of shoulder/upper arm injuries than karate (IPR=4.31, 95% CI: 2.84-6.55) or taekwondo (IPR=9.75, 95% CI: 3.53-26.91) participants. There were also higher proportions of neck injuries sustained by judo participants compared to karate (IPR=4.73, 95% CI: 1.91-11.70) or taekwondo (IPR=4.17, 95% CI: 1.02-17.06) participants. Pediatric martial arts injuries differ by discipline. Understanding these injury patterns can assist with the development of discipline-specific preventive interventions. PMID:16914371

  4. Present state of research and development of atomic energy in five Asian countries

    International Nuclear Information System (INIS)

    The survey group for Asian atomic energy cooperation was dispatched by the Japanese government, and toured Philippines, Indonesia, Malaysia, Thailand and Bangladesh from September 7 to 19, 1980. The present state of atomic energy development and the energy situation in respective countries were surveyed through the exchange of opinion and the inspection of related facilities. The Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology was concluded in June, 1972, and 12 countries have participated in it. It was impressive that respective countries have the peculiar energy policies corresponding to their objective conditions. They regard atomic energy as the important substitute energy for petroleum, but the fear about the safety of atomic energy and the movement against nuclear power generation have been growing considerably. The research and development on atomic energy are carried out very actively in respective countries, and the construction of large-scale research centers was commenced in Indonesia, Malaysia and Bangladesh. Research reactors have been operated in Philippines, Indonesia and Thailand since about 20 years ago, and the utilization of radioisotopes and radiation has been studied. The cooperation of Japan with these countries is far behind that of other advanced countries. (Kako, I.)

  5. Present state and future trends of pine forests of malam jabba, swat district, Pakistan

    International Nuclear Information System (INIS)

    Present state and future trend of pine forests of Malam Jabba, Swat district, Pakistan explored. We focused on vegetation composition, structure, diversity and forests dynamics. Thirteen stands were sampled by Point Centered Quarter method. Among all stands four monospecific forests of Pinus wallichiana attained highest density ha-1 except in one stand where Picea smithiana attained 401 trees ha-1. Unlike density, the basal area m2 ha-1 of these stands varies stand to stand. Based on floristic composition and importance value index, five different communities viz Pinus wallichiana-Picea smithiana; Picea smithiana-Pinus wallichiana; Abies pindrow-Pinus wallichiana; Pinus wallichiana-Abies pindrow; Abies pindrow-Picea smithiana and 4 monospecific forests of Pinus wallichiana were recognized. Size class structure of forests showed marked influence of anthropogenic disturbance because not a single stand showed ideal regeneration pattern (inverse J shape distribution). Future of these forests is worst due to absence trees in small size classes. Gaps are also evident in most of the forest stands. Stand diversity, richness, equitability and Simpson dominance values formulated on single stand basis. Diversity of Abides pindrow and Pinus wallichiana stand was highest because these stand occupied dominant species, while lowest diversity observed in some Pinus wallichiana and Picea smithiana stand as these stands have mark difference between the dominance of two species. In the monospecific forests, the diversity level was zero, suggesting the monopolization of resources by one species or elimination of other tree species in these stands. (author)

  6. Assessing the state of environmental quality in cities - A multi-component urban performance (EMCUP) index.

    2015-11-01

    Urban environmental quality indices can provide policy makers and the public with valuable information. However, common assessment tools have several shortcomings: most indices do leave out some important components of the state of urban environmental quality; they use a relative assessment in which urban environmental performance is evaluated relative to other cities, not against established environmental benchmarks; and only a few assessment tools compare urban performance to environmental quality standards. This paper presents a new multi component urban performance (EMCUP) index aiming to tackle those shortcomings. It analyses the overall state of urban environmental quality by using a list of indicators to evaluate key urban environmental quality topics such as air, water, open space, sanitation and solid waste. It presents an absolute score calculated in relation to both the standard and desired optimum levels. The use of the index is demonstrated by three Israeli cities. PMID:26334706

  7. Extended block diagram method for a multi-state system reliability assessment

    International Nuclear Information System (INIS)

    The presented method extends the classical reliability block diagram method to a repairable multi-state system. It is very suitable for engineering applications since the procedure is well formalized and based on the natural decomposition of the entire multi-state system (the system is represented as a collection of its elements). Until now, the classical block diagram method did not provide the reliability assessment for the repairable multi-state system. The straightforward stochastic process methods are very difficult for engineering application in such cases due to the 'dimension damnation'-huge number of system states. The suggested method is based on the combined random processes and the universal generating function technique and drastically reduces the number of states in the multi-state model

  9. Presentation on the role or risk assessment in FUSRAP remedial planning

    International Nuclear Information System (INIS)

    Although the primary emphasis of the FUSRAP program is to mitigate hazards by removing and disposing of contamination exceeding relevant generic guidelines, current FUSRAP protocol allows for application of supplemental risk-based standards in unique cases where generic standards are inappropriate. This presentation provides background information on the rationale supporting current generic cleanup standards, and how site-specific, risk-based standards can be applied to improve the cost effectiveness of overall remedial strategies. The current DOE process for development, review and granting of supplemental standards is discussed. The discussion includes a description of experience being gained through development of supplemental standards for the Albany Research Center (ARC) FUSRAP site. In particular, the presentation focuses on the methodology used to assess potential exposure risks posed by residual contamination at the ARC, cost and cost-benefit information compiled to support application of supplemental standards at ARC, and general issues identified during the development of supplemental standards. Criteria used to evaluate the appropriateness of applying supplemental standards to a specific situation are discussed. Finally, several examples of residual contamination at FUSRAP sites which may be considered for supplemental standards are identified and discussed

    Climate change impacts ecosystems in many ways, from effects on species to phenology to wildfire dynamics. Assessing the potential vulnerability of ecosystems to future changes in climate is an important first step in prioritizing and planning for conservation. Although assessments of climate change vulnerability commonly are done for species, fewer have been done for ecosystems. To aid regional conservation planning efforts, we assessed climate change vulnerability for ecosystems in the Southeastern United States and Caribbean.First, we solicited input from experts to create a list of candidate ecosystems for assessment. From that list, 12 ecosystems were selected for a vulnerability assessment that was based on a synthesis of available geographic information system (GIS) data and literature related to 3 components of vulnerability—sensitivity, exposure, and adaptive capacity. This literature and data synthesis comprised “Phase I” of the assessment. Sensitivity is the degree to which the species or processes in the ecosystem are affected by climate. Exposure is the likely future change in important climate and sea level variables. Adaptive capacity is the degree to which ecosystems can adjust to changing conditions. Where available, GIS data relevant to each of these components were used. For example, we summarized observed and projected climate, protected areas existing in 2011, projected sea-level rise, and projected urbanization across each ecosystem’s distribution. These summaries were supplemented with information in the literature, and a short narrative assessment was compiled for each ecosystem. We also summarized all information into a qualitative vulnerability rating for each ecosystem.Next, for 2 of the 12 ecosystems (East Gulf Coastal Plain Near-Coast Pine Flatwoods and Nashville Basin Limestone Glade and Woodland), the NatureServe Habitat Climate Change Vulnerability Index (HCCVI) framework was used as an alternative approach for assessing

  16. Using fiction to assess mental state understanding: a new task for assessing theory of mind in adults.

    Directory of Open Access Journals (Sweden)

    David Dodell-Feder

    Full Text Available Social functioning depends on the ability to attribute and reason about the mental states of others--an ability known as theory of mind (ToM. Research in this field is limited by the use of tasks in which ceiling effects are ubiquitous, rendering them insensitive to individual differences in ToM ability and instances of subtle ToM impairment. Here, we present data from a new ToM task--the Short Story Task (SST--intended to improve upon many aspects of existing ToM measures. More specifically, the SST was designed to: (a assess the full range of individual differences in ToM ability without suffering from ceiling effects; (b incorporate a range of mental states of differing complexity, including epistemic states, affective states, and intentions to be inferred from a first- and second-order level; (c use ToM stimuli representative of real-world social interactions; (d require participants to utilize social context when making mental state inferences; (e exhibit adequate psychometric properties; and (f be quick and easy to administer and score. In the task, participants read a short story and were asked questions that assessed explicit mental state reasoning, spontaneous mental state inference, and comprehension of the non-mental aspects of the story. Responses were scored according to a rubric that assigned greater points for accurate mental state attributions that included multiple characters' mental states. Results demonstrate that the SST is sensitive to variation in ToM ability, can be accurately scored by multiple raters, and exhibits concurrent validity with other social cognitive tasks. The results support the effectiveness of this new measure of ToM in the study of social cognition. The findings are also consistent with studies demonstrating significant relationships among narrative transportation, ToM, and the reading of fiction. Together, the data indicate that reading fiction may be an avenue for improving ToM ability.

    2016-03-01

    Here, we present the first catheter-based optical coherence elasticity measurement using a newly developed super fast intravascular optical coherence tomography (OCT) system. The system is based on a 1.5 MHz Fourier Domain Mode Locked laser and a 1.2 mm outer diameter motorized catheter. To detect the local elastic properties, the micro-motor is programmed to actuate the laser beam in a "step-by-step" mode at 1 revolution per second; which can potentially be increased to > 10 revolutions/s. The beam is scanned in a limited number (up to 50) of angular steps, at each of which the beam position is held stable. When the laser beam is stable, the phase difference across a variable number of A-lines can be computed to assess the elastic displacement. Choosing a proper window delay, local elastic tissue displacement and strain can be quantified based on the phase shift. We conducted ex-vivo experiments with a cylindrical phantom where the elastic property changes at different angular positions. A syringe pump was used to generate variable pressure loading, which is synchronized to the motor driving signal. The experimental results show that the elastic displacements are detected to be different at different angular positions. The results of elastic properties detection in human artery will also be demonstrated.

    Full-field optical coherence tomography (FFOCT) offers a non-invasive method of obtaining images of biological tissues at ultrahigh resolution (1µm in all 3 directions) approaching traditional histological sections. Previous clinical studies have shown the high efficiency of this imaging technique for the detection of cancer on various organs. This promises great potential of the technique for an ex-vivo quick analysis of surgical resections or biopsy specimens, in the aim to help the surgeon/radiologist decide on the course of action. Here we will present some of the latest technical developments on a FFOCT system which can produce 1cm2 images with 1 µm resolution in 1 minute. Larger samples, up to 50mm diameter, can also be imaged. Details on the large sample handling, high-speed image acquisition, optimized scanning, and accelerated GPU tiles stitching will be given. Results on the clinical applications for breast, urology, and digestive tissues will also be given. They highlight the relevance of the system characteristics for the detection of cancer on ex-vivo specimens. FFOCT now appears clearly as a very fast and non-destructive imaging technique that provides a quick assessment of the tissue morphology. With the benefit of both new technical developments and clinical validation, it turned into a mature technique to be implemented in the clinical environment. In particular, the technique holds potential for the fast ex-vivo analysis of excision margins or biopsies in the operating room.

However, usability of previously collected samples and the effects of environmental conditions on the samples during collection have not been assessed in detail. In five studies we document the effects of sample volume, handling and storage conditions, type of collection device, and oral sampling location, on quantity, quality, and genetic assessment of DNA extracted from cells present in saliva. Methods Saliva samples were collected from ten adults in each study. Saliva volumes from .10-1.0 ml, different saliva collection devices, sampling locations in the mouth, room temperature storage, and multiple freeze-thaw cycles were tested. One representative single nucleotide polymorphism (SNP in the catechol-0-methyltransferase gene (COMT rs4680 and one representative variable number of tandem repeats (VNTR in the serotonin transporter gene (5-HTTLPR: serotonin transporter linked polymorphic region were selected for genetic analyses. Results The smallest tested whole saliva volume of .10 ml yielded, on average, 1.43 ± .77 μg DNA and gave accurate genotype calls in both genetic analyses. The usage of collection devices reduced the amount of DNA extracted from the saliva filtrates compared to the whole saliva sample, as 54-92% of the DNA was retained on the device. An "adhered cell" extraction enabled recovery of this DNA and provided good quality and quantity DNA. The DNA from both the saliva filtrates and the adhered cell recovery provided accurate genotype calls. The effects of storage at room temperature (up to 5 days, repeated freeze-thaw cycles (up to 6 cycles, and oral sampling location on DNA extraction and on genetic analysis from saliva were negligible. Conclusions Whole saliva samples with volumes of at least .10 ml were sufficient to extract good quality and quantity DNA. Using

    Siberian forests occupy a significant part of the Asian continent. Their role as an essential component of the Earth's surface, biomass and oxygen producer is increasing annually. Expanded reproduction of taiga forests necessitated by the intensive development of Siberian productive forces, results in an evergrowing need of forest productivity constancy and increase. Proper forest exploitation is a crucial part of the solution of such important problems as the rational use of land and water resources, stable crop yields, and the creation of favourable conditions for human life.To solve these important economic problems, the Siberian branch of the USSR Academy of Sciences has devised a long-term programme of ecological monitoring of Siberian forest resources using aerospace techniques. The programme provides for the establishment and improvement of ecogeographical and physicotechnological principles of the remote sensing of forests and the development of fundamental forest-biological research based on new methodologies, the results of which are used to solve urgent forestry and nature protection problems. The research is carried out in the following major directions: studying spectral characteristics of forest vegetation for forest-state indication; thematic mapping of taiga territories; assessing biological productivity of natural complexes; environmental state monitoring; fire protection of forests; pest and disease control; developin instruments and methods for automatized aerospace data processing for real-time use.We consider forest-state monitoring to be one of the crucial tools in providing the optimum use of forest ecosystems for resource and ecological functions.

    The immune system is a complex organization system possessing its hierarchical structure of morphological and functional elements united into an integral unity. Therefore the immune system state should be characterized as an integral unity. The use of the NovoSpark Visualisation approach (Canada) to multidimensional data visualization provides the visual image representing the immune system state as an integral unity. This uniform visual characteristic is formed by values of individual immunological parameters in every person. The curves appropriating the immune system states in breast cancer patients with and without cancer progression (hematogenous metastases) during a 3-year follow-up are located in disjoint areas of the multidimensional data space. The obtained data suggest that the immune system greatly influences the course and outcome of breast cancer. In prospect this approach can be useful for a breast cancer outcome prognosis.

  10. Assessment of radiological risk due to natural radioactivity present in some building materials used around Kalpakkam

    International Nuclear Information System (INIS)

    Building materials cause direct radiation exposure because of their uranium, thorium and potassium content. The need for determination of natural radioactivity content in building materials arises from the growing attention paid to its potential radiation effects and consequent concern of many producers of such materials. In this paper around 97 samples of commonly used building materials have been collected randomly around Kalpakkam and analyzed for natural radioactivity due to presence of primordial radionuclide 238U, 232Th and 40K using gamma spectrometry. The activity of different building material obtained in this study ranged from ≤ 3-72 Bq/kg for 238U, ≤ 5-163 Bq/kg for 232Th and ≤ 38-1481 for 40K, respectively. The highest 238U, 232Th and 40K was found in asbestos, red soil and granite, respectively. The minimum values of 238U, 232Th and 40K were found in wood. The radium equivalent activity (Raeq), external hazard index (Hex), internal hazard index (Hin), absorbed dose rate (D) in air, annual effective dose equivalent (Eeff) and activity concentration index (I) were evaluated to assess the radiation hazard for people living in dwelling made of building materials studied. All the building materials showed radium equivalent activity (Raeq) values lower than the limit of 370 Bq/kg set in United Nations Scientific Committee on the Effects of Atomic Radiation Report (UNSCEAR,1988).The resulting annual effective dose equivalent due to total external terrestrial radiation is less than 1 mSv/year. The results presented indicate that commonly used building material in Kalpakkam does not exceed the proposed radioactivity criterion level. (author)

  11. Assessment of mercury emissions inventories for the Great Lakes states

    International Nuclear Information System (INIS)

    Anthropogenic mercury (Hg) air emissions for the eight Great Lakes states in 1999-2000 were evaluated by analyzing three inventories. The US Environmental Protection Agency (EPA) National Emissions Inventory (NEI) had the most complete coverage for all states, and total Hg emissions ranged from 4226 lb in Minnesota to 15,828 lb in Pennsylvania. Coal-fired electric utilities accounted for 52.7% of the region's Hg emissions, varying from 20.2% of the total in New York to 67.5% in Ohio. Other important contributors to regional emissions included municipal waste combustion (5.6%), mercury-cell chlor-alkali plants and hazardous-waste incinerators (4% each), stationary internal combustion engines (ICEs) (3.5%), industrial, commercial, and institutional (ICI) boilers (3.3%), and lime manufacturing (3.0%). Although medical waste incineration accounted for just over 1% of regional emissions using the original classifications, the inclusion of health care facilities that may have been inappropriately identified with other sectors would increase the sector to 4.5% of regional emissions (and decrease the stationary ICE sector to 1.4% of the regional total). There were substantial differences for some sectors between the NEI and the Great Lakes Regional Air Toxics Emissions Inventory (GLEI), as well as unexplained differences within inventories between states (particularly for the cement, lime, and asphalt industries, and for lamp breakage). Toxics Release Inventory data for 2000 mainly covered electric utilities, and differences from the NEI were significant for several states. An independent assessment indicates the possibility of underestimated Hg emissions by about twofold for ICI boilers, although data for the sector (in particular concerning fuel oil emissions) are highly uncertain. Limited data indicate the likelihood of significant underestimates of electric arc furnace mercury emissions in the NEI and GLEI inventories. Several measures are here identified for improving

    Full Text Available Abstract We assessed CD4 count at initial presentation for HIV care among ≥50-year-olds from 1997-2007 in 13 US and Canadian clinical cohorts and compared to 3 and 95% confidence intervals ([,] were determined using linear regression stratified by age category and adjusted for gender, race/ethnicity, HIV transmission risk and cohort. From 1997-2007, the proportion of individuals presenting for HIV care who were ≥50-years-old increased from 17% to 27% (p-value 3; ≥50-year-olds: 7 [5 , 9] cells/mm3, after adjusting for sex, race/ethnicity, HIV transmission risk group and cohort; however, increases in the two groups were similar after 2000. A greater proportion of older individuals had an AIDS-defining diagnosis at, or within three months prior to, first presentation for HIV care compared to younger individuals (13% vs. 10%, respectively. Due to the increasing proportion, consistently lower CD4 counts, and more advanced HIV disease in adults ≥50-year-old at first presentation for HIV care, renewed HIV testing efforts are needed.

  1. Ecological effects assessment: requirements vs state-of-the-art

    International Nuclear Information System (INIS)

    Concerns for environmental quality, the ecologist's understanding of ecosystems, and the ability to quantitatively sample and evaluate hypotheses have contributed to current requirements and the state-of-the-art in ecological effects assessments in refard to nuclear power plants. The current cooling system approaches, data collection programs, and ecological effects assessments reflect these contributions. Over a decade of experience provides the basis for a timely review and evaluation of current proactice. The magnitude of economic and environmental resources being committed to cooling system alternatives mandates that the decision-making process result in as many optimal choices as possible. In addition, the resources being devoted to environmental data collection and integration provide considerable motivation for providing meaningful input to the decision-making process. It is maintained that the input should be as quantitative and as free from subjective content as is reasonably possible. An alternative viewpoint suggests that the past several decades of experience be considered but a first step, and the current task to be one of designing a second step

  4. 1944 Water Treaty Between Mexico and the United States: Present Situation and Future Potential

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Historically and culturally, water has always been considered to be a critical issue in Mexico- USA agenda. Along the 3 140-km border between Mexico and the United States, there is intense competition over the adequate availability of water. Water uses in urban border areas have continued to increase exponentially due to steadily increasing levels of population growth. Rapid industrialisation and urbanisation have resulted in more intensive patterns of water consumption and use. Agricultural water demands continue to be high. Mexico and the United States have established institutions and agreements to manage and protect rivers in the border region. The Treaty between Mexico and the United States for the Utilisation of Waters of the Colorado and Tijuana Rivers and of the Rio Grande was signed in 1944. With the turn of the century, the growing urban centers along the Rio Grande (Rio Bravo, where the river becomes the international boundary, started increasingly to depend on groundwater. This situation was not specifically addressed in the 1944 Treaty, especially as groundwater use at that time was not so significant.

    Full Text Available Surface mining of brown coal changed Iron mountains basin region fundamentally. Hundreds of millions of hauled masses significantly affected the landscape appearance. Involvement of government authorities and citizens of the affected towns and villages is essential and participation is expected. For proper assessment of the projected mining intent with subsequent remediation of the consequences, processing of 3D models and interactive visualizations options shared with web technology is an important factor. Creation of dump body 3D model, including internal composition, can play important role in various tasks solving, for example in hydrology or geotechnics. High-quality processing of these materials requires use of modern surveying technology, CAD systems and various tools of computer graphics processing.

    We are constructing a new computerized test of reading comprehension called the Reading Strategy Assessment Tool (R-SAT). R-SAT elicits and analyzes verbal protocols that readers generate in response to questions as they read texts. We examined whether the amount of information available to the reader when reading and answering questions influenced the extent to which R-SAT accounts for comprehension. We found that R-SAT was most predictive of comprehension when the readers did not have access to the text as they answered questions. PMID:17695345

    The territory of the Republic of Armenia (RA) occupies an area 29.8 sq. km, the major part of which - 2077 hectares - falls on farmlands located at a height 400-3200m a.s.l. Such a variation in altitude complicates development of territories especially in the case they have an extensive character stemmed from the Soviet era: land plough-up on sites lying at a very steep angle of decline - >20 grade, unregulated grazing and so on. A long-term, unplanned and unregulated use of farmlands entailed intense washout of upper soil horizon, which subsequently provoked intense development of erosion and degradation of lands. A practicable solution to this problem is a scientifically and methodically grounded assessment of ecological state of farmlands and economically 'competent' planning and management of agricultural resources. With the view of developing animal husbandry and managing pastures/hayfields, in 2011-2012 the Government of the Republic of Armenia under support of the World Bank implemented a Farm Resources Management and Competitiveness Program. The goal of the Program is ceasing a trend to overgrazing and degradation of close-to-village sites, using remote pastures/hayfields in the best effective manner, improving feed production and animal feeding networks, and promoting a growth in animal feed production volumes. To achieve that, the following works were planned and implemented successfully in 23 rural communities of 6 marzes of the RA, which was done by 3 stages. In preparatory stage • Accessible web resources - programs and sites (Google Earth, www.landcocer.org) with a view of identifying information to support implementation of the planned activities, were explored and evaluated. • Cartographic material (topographic maps sc.1:10000, landscape maps, panchromatic and multi-spectral high- and medium - resolution satellite images /LANDSAT ETM, QuickBird/ and other thematic cartographic and archival material) required for subsequent treatment of

    Full Text Available Entrepreneurship is one of the main driving forces of the national economies. In Poland, more and more jobs are created in private enterprises, set up and running by entrepreneurs. Entrepreneurs are characterized as people, which seize the opportunity to act, have higher self-esteem and a greater sense of control over their lives, and they, usually become successful people. This causes a widespread conviction, that the promotion of entrepreneurship, may result in maximizing the success of both, individual and in the scale of the national economy as well. Therefore, it becomes important to develop standards in the field of entrepreneurship education, the greater numbers of people would have been able to achieve a professional success. This article presents the essence of the entrepreneurship and the role of education, in entrepreneurship’s excitation or strengthening. Also a practical example of the implementation of these provisions by one of the Polish Universities - Czestochowa University of Technology, is presented.

  4. CT and the heart: Present state of the art and its future

    International Nuclear Information System (INIS)

    Overview of non-invasive cardiac computed tomography (CCT) presently technologically feasible - with an outlook on the future. CCT seems to be an addition to the cardiodiagnostic imaging spectrum of cardiac isotope scanning and cardiosonography already firmly established; and it will probably soon have to establish its rank. The indications for CCT already proven and those avaited in the future will be systematically analyzed in this presentation. Conventional present-day CCT with long scanning times of 3-5 seconds has already provided satisfactory clinical information, considering the fact that there is slow motion of the damaged area in myocardial desease as experimentally shown by an over 20 min long arrest of contrast-material (given i.v.) in the infarcted areas. EKG-gated scanning and reconstruction techniques under development will provide better spatial and chronological resolution. However, much development is yet to be done, it is to be expected that CCT will eventually render data about the function of a specific area of the ventricular wall. Decreased scanning times and scanning intervals will provide dynamic studies of cardiac function and alow time/concentration examinations. These latter studies will be especially valuable to demonstrate the intracavitary cardiac flow in detail. (orig.)

    Overview of non-invasive cardiac computed tomography (CCT) presently technologically feasible - with an outlook on the future. CCT seems to be an addition to the cardiodiagnostic imaging spectrum of cardiac isotope scanning and cardiosonography already firmly established; and it will probably soon have to establish its rank. The indications for CCT already proven and those awaited in the future will be systematically analyzed in this presentation. Conventional present-day CCT with long scanning times of 3-5 seconds has already provided satisfactory clinical information, considering the fact that there is slow motion of the damaged area in myocardial desease as experimentally shown by an over 20 min long arrest of contrast-material (given i.v.) in the infarcted areas. EKG-gated scanning and reconstruction techniques under development will provide better spatial and chronological resolution. However, much development is yet to be done, it is to be expected that CCT will eventually render data about the function of a specific area of the ventricular wall. Decreased scanning times and scanning intervals will provide dynamic studies of cardiac function and alow time/concentration examinations. These latter studies will be especially valuable to demonstrate the intracavitary cardiac flow in detail.

  7. LIBERALISATION OF THE ELECTRICITY SECTOR IN THE EUROPEAN UNION: PRESENT STATE AND SOME OPEN QUESTIONS

    Energy Technology Data Exchange (ETDEWEB)

    Nunez, A.

    2007-07-01

    The liberalisation of the electricity sector started approximately 10 to 15 years ago, depending on the country. Nonetheless, there is still no general agreement on the liberalisation model this sector should follow, mainly because of the discussion of whether the liberalisation is an end in itself, or a means for -basically- lower energy prices. The complexity of the sector and the resilience of the incumbents' market power have currently placed the liberalisation process at a crossroad. In the EU, entrenched national interests are another obstacle to deal with. In this article, we first give an overview of the different liberalisation processes in the electricity sector and then summarize the pending challenges from an EU perspective. Next, we argue that the EU should focus on conditions aiming at implementing an effective liberalisation process, rather than on a formal liberalisation approach. We show how asymmetries between non-sector regulations in the European states and among companies create an uneven playing field, contrary to the European vision of an internal competitive energy market. We end the article studying the compatibility of the current European regulatory framework with the upcoming challenges in the energy sector. (auth)

    Voltage-gated sodium channels represent important drug targets. The implementation of higher throughput electrophysiology assays is necessary to characterize the interaction of test compounds with several conformational states of the channel, but has presented significant challenges. We describe a novel high throughput approach to assess the effects of test agents on voltage-gated sodium currents. The multiple protocol mode of the automated electrophysiology instrument IonWorks Barracuda was used to control the level of inactivation and monitor current stability. Good temporal stability of currents and spatial uniformity of inactivation were obtained by optimizing the experimental conditions. The resulting assay allowed for robust assessment of state-dependent effects of test agents and enabled direct comparison of compound potency across several sodium channel subtypes at equivalent levels of inactivation.

    Additive manufacturing (AM) is a technology that first emerged in 1987 with stereolithography (SL) of plastic materials from 3D Systems. It saw light use for rapid prototyping and very low volume production for a number of years. However, in the past few years AM of metallic materials has become a practical fabrication technology, use is rapidly increasing and is projected to continue with double digit growth in coming years. The promise and flexibility shown by AM has spurred efforts to begin standardization of this type of process. This paper provides an assessment of the state of the art for in-situ process monitoring of AM processes with an emphasis on the production of metallic components. It is seen that with the implementation of proper process control there is potential to create reliable and reproducible materials and geometries previously unachievable using metal removal based means of production. A reliable methodology for detection and control of microstructure and defects would be of great value in terms of enabling broader AM utilization.

  14. Assessment of terrestrial gamma-radiation in Northern State

    International Nuclear Information System (INIS)

    This study is primarily conducted at the request of Northern State government to investigate the present of abnormal radioactivity in Northern State as claimed publicly. Activity concentration of 238 U, 232 Th, 40 K and 137Cs in soil samples collected from different locations have been measured using high resolution γ-spectrometry. The average concentration were 19±4 Bg/kg for 238U, 47±11 Bq/kg for 232Th, 317±65 Bq/kg for 40K and 2.26 Bq/kg for 137Cs which means a very little contribution to the total exposure. The obtained results were found to be lower than the corresponding global values reported in the UNSCEAR publication for normal background areas. Absorbed dose rate in air at a height of 1m from the ground was calculated using six sets of dose rate conversion factors and corresponding annual effective dose was estimated. On the average, the values obtained were 52.90, 50.43, 50.41, 43.54, 44.07 and 45.85 nGy.h-1 with corresponding annual effective doses of 64.93, 61.89, 61.87, 53.43, 54.08 and 56.27 μSv/y respectively. These values lie with in the worldwide range for normal radiation areas. The results obtained using these different DRCFs, although the approach used for their estimation was different, revealed no remarkable variation. Using Geographical Information System (GIS), prediction maps for concentration of 238U, 232Th, 40K and 137Cs was produced. Also a map for absorbed dose rate in air at a height of one-meter above ground level was produced, which showed a trend of increase form the west towards south-east of the State.(Author)

    Full Text Available The aim of this paper is to show how international standards dealing with library statistics and indicators (ISO 2789, ISO 11620 and others projects which are still under development can be used as reference documents and strategic tools in a performance assessment process. The task is not an easy one, because it requires linking up somewhat complex entities such as the standardization work characteristics, the capacity of statistics to account for reality and, lastly, the variety and speed of libraries’ advancement. Nevertheless, ISO 2789 (International Library Statistics and ISO 11620 (Performance indicators for libraries, which are based on an international consensus of experts, take into account, as much as possible, the recent evolutions in library structures and services. In addition, they are related to classical and shared assessment models. So, although their aim is not to draw up an assessment framework, they reveal themselves useful for basic operations in such a framework: to define objects and services, and to classify, count and build appropriate indicators. Moreover, as the issue of quantifying and promoting intangible assets becomes a concern in the public sector, these standards can be seen as a first attempt to define library resources and services as such intangible assets. Finally, the challenge of forthcoming evolutions of these standards is the ability to stay up-to-date in a very quickly evolving context. More precisely, the increase in the usability of these standards must be based on an ongoing search for more consistent data and relevant indicators. The question of improvement of the general design of the statistics and indicators standards family should also be addressed.

    A 70-year-old man was referred by his rheumatologist to our dermatology clinic for evaluation of dermatitis on his right arm that appeared 3 months earlier. The skin lesion was asymptomatic and the patient denied current systemic symptoms, including fever, chills, and joint pain; however, 10 months prior to this presentation he experienced arthritis in the left knee. At that time, Borrelia serology revealed positive IgG (6.07; <0.8 negative, 0.8 to 0.99 borderline, ≥1 positive) and negative IgM titers. The patient had not received treatment for Lyme disease in the past. He was referred to rheumatology for evaluation of possible Lyme disease but did not follow up until 10 months later. The arthritis has since resolved. He travels frequently to France and recalls multiple tick bites during these trips. PMID:27502263

    @@ Primary osteoporosis, a commonly encountered metabolic bone disease in the postmenopausal women and the aged people, can be classified by modern medicine into postmenopausal osteoporosis (Type I) and senile osteoporosis (Type II). The disease seriously affects health and quality of life of the people as it often cause ostealgia, fracture and the secondary symptoms or diseases. Presently, the pharmacotherapy (including both Chinese herbal drugs and western drugs) remains the first among all other therapeutic methods which are mainly adopted in treatment of the disease at home and abroad. Studies related have been curried out quite early and systematically, and considerable progress has been made, but limit of the pharmacotherapy has also been found. Certain non-drug treatments (such as dietetic therapy, physical exercise, acupuncture and moxibustion, and qigong, especially acupuncture and moxibustion therapy, although with a late start, have been proved effective with satisfactory results. The following is a summary of all the contributions concerned.

    FFOCT (Full Field Optical Coherence Tomography) is a novel optical technology that gives access to very high resolution tomography images of biological tissues within minutes, non-invasively. This makes it an attractive tool to bridge the gap between medical imaging modalities (MRI, ultrasound, CT) used for cancer lesion identification or targeting and histological diagnosis. Clinical tissue specimens, such as surgical cancer margins or biopsies, can potentially be assessed rapidly, by the clinician, in the aim to help him decide on the course of action. A fast FFOCT prototype was built, that provides 1cm2 images with 1 µm resolution in 1 minute, and can accommodate samples up to 50mm diameter. Specific work was carried out to implement a large sample holder, high-speed image acquisition system, optimized scanning, and accelerated GPU tiles stitching. Results obtained on breast, urology, and digestive tissues show the efficiency of the technique for the detection of cancer on clinical tissue specimens, and reinforce the clinical relevance of the technique. The technical and clinical results show that the fast FFOCT system can successfully be used for a fast assessment of cancer excision margins or biopsies providing a very valuable tool in the clinical environment.

Two types of training against the act of terrorism had been held in Tokai Works of the Japan Nuclear Cycle Development Institute (JNC) to grasp the present situation of JNC Tokai Works and improve the countermeasure against the terrorism. The first training was for the incendiarism and the second one was for the injury. Consequently the revealed points to be improved were the followings. (1) Keeping a sense of crisis. The countermeasure against terrorism should be instructed and trained to realize the sense of crisis, that is, uncertainty of the time and the kind of terrorism. (2) Organization of the structure against the terrorism. The structure for the contingency should to organized to strengthen the guard structure by forming the pursuit team, the guard team and so on constituted by JNC's staff members. (3) Preparation of equipments against the terrorism. The coloring ball, club, two-pronged weapon, shield, knifeproof vest and so on should be provided the guards of to strengthen the countermeasure before the police's arrival. (4) Preparation and announcement of manuals. The manuals against terrorism for the ordinary stuff members should be prepared and used in the training to make the ordinary stuff's countermeasure more effective. (author)

  6. The present state of research on the vitrification of concentrated solutions of fission products (1962)

    International Nuclear Information System (INIS)

    The present report gives the actual point of studies on vitrification of concentrated solutions of fission products. An active cell, giving glasses in crucibles, permitted to study various glass compositions. The leaching rate from the glass raises 1 to 2 10-7 g of glass/cm2/day. Activity loss by volatility during vitrification remains weak and often below 0.1 per cent of total activity. Off gas cleaning is made easier by presence of filter which is compound of granules including iron oxide. After saturation the content of this filter can be melt. Moreover different processes are in experimentation for a more important production. Daily 72 liters of solution containing tracer activity are treated in a continuous calcination and vitrification plant. The loss in 106Ru is still important and a modification of installation has been necessary. A pot vitrification plant is in study. In order to reduce cost of processing the possibility to pour glass after melting is actuality in study. A production set of very active glass is also in project. (authors)

    2012-04-01

    An engineering geological map can be defined as a geological map with a generalized representation of all the components of a geological environment which are strongly required for spatial planning, design, construction and maintenance of civil engineering buildings. In Wallonia (Belgium) 24 engineering geological maps have been developed between the 70s and the 90s at 1/5,000 or 1/10,000 scale covering some areas of the most industrialized and urbanized cities (Liège, Charleroi and Mons). They were based on soil and subsoil data point (boring, drilling, penetration test, geophysical test, outcrop…). Some displayed data present the depth (with isoheights) or the thickness (with isopachs) of the different subsoil layers up to about 50 m depth. Information about geomechanical properties of each subsoil layer, useful for engineers and urban planners, is also synthesized. However, these maps were built up only on paper and progressively needed to be updated with new soil and subsoil data. The Public Service of Wallonia and the University of Liège have recently initiated a study to evaluate the feasibility to develop engineering geological mapping with a computerized approach. Numerous and various data (about soil and subsoil) are stored into a georelational database (the geotechnical database - using Access, Microsoft®). All the data are geographically referenced. The database is linked to a GIS project (using ArcGIS, ESRI®). Both the database and GIS project consist of a powerful tool for spatial data management and analysis. This approach involves a methodology using interpolation methods to update the previous maps and to extent the coverage to new areas. The location (x, y, z) of each subsoil layer is then computed from data point. The geomechanical data of these layers are synthesized in an explanatory booklet joined to maps.

    Rice, E. E.

    1978-01-01

    An approach to analyze the total energy required for overall support of space launch vehicles is outlined along with some of the basic data required for such analyses. Selected results obtained by using this approach are presented for various past (some are already phased out), present, and future NASA launch vehicles, including an estimate of the total annual energy required to support one projected NASA launch vehicle traffic model. The material presented is expected to give a better insight into the details of an energy impact analysis. Major conclusions are that: (1) for expendable launch vehicle systems, the energy required to manufacture hardware and support launch operations is most significant; (2) for totally reusable systems, the energy required to process/manufacture propellants and fluids is by far the most significant contributor; and (3) up to 1991, the projected highest annual energy requirement for the NASA launch vehicles does not constitute a significant energy impact relative to the nation's total energy needs.

  10. Accessibility assessment in municipal schools of Uberaba, Minas Gerais state

    Directory of Open Access Journals (Sweden)

    Victor Ruan Carvalho Soares

    2015-03-01

    Full Text Available Introduction: Architectural barriers generate difficulties, significantly impair people’s access to different environments, and limit accessibility. In the Brazilian public school system, these questions become more relevant when the process of school inclusion of students with special needs for mobility is analyzed. The process of school inclusion is intrinsically associated with the accessibility condition of schools. Through the ‘Accessible School Program‘, schools have received financial incentive to adapt their physical spaces according to accessibility. Objective: To describe the accessibility of the schools that have taken part in the ‘Accessible School Program’ in the municipality of Uberaba, Minas Gerais state. The study also aimed to identify the materials purchased and the adjustments and repairs implemented, evaluating whether the changes attend the technical standard of accessibility and agree with the recommended proposals. Methodology: This is an exploratory-descriptive study of quantitative nature; it was conducted in two phases through documental research and field study. Eleven municipal schools that participated in the ‘Accessible School Program’ were identified. Results: Most of the schools presented problems in almost all the items evaluated: sidewalks, common inside area, door squares, restrooms, locker rooms, swimming pools, parking, cinemas or theatres, auditoriums, stadiums, gymnasiums, concert halls, conference rooms and school furniture. Conclusion: The public schools evaluated present limitations regarding accessibility; the physical barriers erected in the past have not been eliminated and they still represent obstacles to be overcome by students with special needs.

  11. Present status of reactor physics in the United States and Japan-II. 6. Present Status of GNF New Nodal Simulator

    International Nuclear Information System (INIS)

    This paper presents core simulator consolidation work done at Global Nuclear Fuel (GNF). The unified simulator needs to supersede the capabilities of past simulator packages from the original GNF partners: GE (Ref. 1), Hitachi (Ref. 2), and Toshiba (Ref. 3). At the same time, an effort is being made to produce a simulation package that will be a state-of-the-art analysis tool when released, in terms of the physics solution methodology and functionality. The core simulator will be capable and qualified for (a) high-energy cycles in the U.S. markets, (b) mixed-oxide (MOX) introduction in Japan, and (c) high-power density plants in Europe, etc. The unification of the lattice physics code is also in progress based on a transport model with collision probability methods. The AETNA core simulator is built upon the PANAC11 software base. The goal is to essentially replace the 1.5-energy group model with a higher-order multigroup nonlinear nodal solution capable of the required modeling fidelity, while keeping highly automated library generation as well as functionality. All required interfaces to PANAC11 will be preserved, which minimizes the impact on users and process automation. Preliminary results show statistical accuracy improvement over the 1.5- group model. The status of the GNF new nodal simulator is presented. It is built on a highly automated software base by combining the best technologies of GE, Hitachi, and Toshiba and will provide a BWR core analysis tool with high functionality and fidelity.

    2011-01-01

    Full Text Available The Common European Framework of Reference (CEFR describes the B2 level as having limited operational proficiency, where speakers have an adequate response to situations normally encountered. In the spoken domain a B2 user is said to interact with a degree of fluency and spontaneity, to produce clear, detailed text on a wide range of subjects and to explain a viewpoint on a topical issue giving the advantages and disadvantages of various options. Besides that, a B2 user should be able to spontaneously depart from the previously prepared presentation material and to interact with an audience to develop interesting parts of his/her presentation. This paper, accordingly, focuses on oral presentations of university students who were put at the B2 level of CEFR. The sample comprises students who study English as their major and students of other departments who take classes of English as a foreign language. The primary method of research is observation done by the teacher while students present previously chosen and prepared topics. The aim of the research is to determine whether the students from the sample, representative of their population, fit into the description and criteria of the B2 level.

  19. Assessment of the quality of drinking water in Khartoum State

    International Nuclear Information System (INIS)

    Assessment of drinking water quality in Khartoum State was the main purpose of this study. Seven sites were selected to represent the area of wells water, relevance to environmental pollution in Khartoum area, Ummbadah near industrial area, Elthawra near a power station, Elfiteihap near the White Nile, Elriyadh near a petroleum station, Elkalakla in the last bus station, Elhag Yousif in the market, as well Eldroshap as control area. Raw and treated water samples were collected from the White Nile, the Blue Nile and the River Nile, wells water and treated water from the three Niles these samples stored in metallic and fiber glass tanks in the rainy and dry seasons. Standard methods were used for samples collection and preparation for the measurements using Atomic Absorption Spectroscopy (AAS) and flame photometer. Thirteen elements were observed and their concentrations determined in the various locations, those are Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mg, Mn, Na, Ni, Pb and Zn. The concentration levels for Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were lower than the detection limits for (AAS), and pre-concentration by physical method was found necessary for these elements, the evaporation method of the drinking water samples were used. The data obtained were compared with the data from literature. The results are generally comparable except the concentration of Fe of the raw water for the River Nile in the two seasons as well as the treated water for the River Nile, the treated water for the River Nile stored in fiber glass tank (rainy season), and the treated water for the White Nile stored in metallic tank (rainy season) are lower than the maximum permissible international levels provided by the World Health Organization (WHO) and the concentration of trace elements in drinking water permitted by the Sudanese Standards and Metrology Organization (SSMO). There is no pollution in the ground water resulting from human activities can be made.(Author)

  1. Assessment of present and future risk to Italian forests and human health: Modelling and mapping

    International Nuclear Information System (INIS)

    A review of ozone pollution in Italy shows levels largely above the thresholds established by EU regulation for vegetation and human health protection. The Italian air quality monitoring network appears quantitatively inadequate to cover all the territorial surface, because of scarcity and unequal distribution of monitoring sites. By applying the integrated assessment model RAINS-Italy to the year 2000, the whole of Italy exceeds the AOT40 critical level for forest, while Northern and central areas show strong potential of O3 impact on human health with ∼11% of territory >10 O3-induced premature deaths. Two scenarios for the year 2020, the Current Legislation and the Maximum Technical Feasible Reduction, show a reduction of AOT40Forest by 29% and 44%, SOMO35 by 31% and 47%, and O3-induced premature deaths by 32% and 48%, compared to 2000. RAINS-Italy can be used to improve the map quality and cover areas not reached by the national monitoring network. - AOT40 and SOMO35 are and will be high enough to affect forest and human health all over Italy.

    The role of hemodynamics in early heart development is poorly understood. In order to successfully assess the impact of hemodynamics on development, we need to monitor and perturb blood flow, and quantify the resultant effects on morphology. Here, we have utilized cardiac optical pacing to create regurgitant flow in embryonic hearts and OCT to quantify regurgitation percentage and resultant morphology. Embryonic quail in a shell-less culture were optically paced at 3 Hz (well above the intrinsic rate or 1.33-1.67 Hz) on day 2 of development (3-4 weeks human) for 5 minutes. The pacing fatigued the heart and led to a prolonged period (> 1 hour) of increased regurgitant flow. Embryos were kept alive until day 3 (cardiac looping - 4-5 weeks human) or day 8 (4 chambered heart - 8 weeks human) to quantify resultant morphologic changes with OCT. All paced embryos imaged at day 3 displayed cardiac defects. The extent of regurgitant flow immediately after pacing was correlated with cardiac cushion size 24-hours post pacing (p-value develop into abnormal valves and septa. Our model produces similar phenotypes as found in our fetal alcohol syndrome and velo-cardio-facial/DiGeorge syndrome models suggesting that hemodynamics plays a role in these syndromes as well. Utilizing OCT and optical pacing to understand hemodynamics in development is an important step towards determining CHD mechanisms and ultimately developing earlier treatments.

    Inayat, Faisal; Hurairah, Abu; Shaikh, Faiq

    2016-01-01

    The Marfan syndrome (MFS) is a pleiotropic, autosomal dominant disorder of connective tissue with highly variable clinical manifestations. It primarily involves the skeletal, cardiovascular, and ocular systems; however, gastrointestinal complications are rare. Herein, we describe the case of a 31-year-old male who initially presented with acute abdominal pain for one day. His imaging features revealed a dilated sigmoid colon, consistent with sigmoid volvulus that was immediately decompressed. Surgical resection was recommended to treat the sigmoid volvulus. Preceding the treatment, the patient underwent an extensive workup, including an echocardiography that revealed aortic root dilatation. His clinical history, physical exam, and echocardiographic findings raised the suspicion for MFS. Subsequently, the diagnosis of MFS was confirmed on genetic testing. This is a case that highlights the multidisciplinary (clinical, radiological, endoscopic, molecular/genetic) approach to diagnose a patient with MFS who presented with symptomatic sigmoid volvulus. As this presentation may be a harbinger of more severe manifestations of MFS, it is important to identify it as such in order to accomodate for timely management. PMID:27382527

    Full Text Available Riverine dams alter both the physical environment and water chemistry, thus affecting species assemblages within these environments. In the United States, dam construction is on the decline and there is a growing trend for dam removal. The Choctawhatchee, Pea, and Yellow Rivers Watershed Management Authority had initiated the permitting process for placing a reservoir dam on the Little Choctawhatchee River (LCR, a tributary to the Choctawhatchee River. The purpose of the proposed reservoir was water supply, and while the permit application has been suspended, history shows that this or related projects are likely to arise in the future. This study collected data on nutrient quality seasonally (four times from 12 sites in the LCR watershed from October 2007 to June 2008 in order to determine pre-dam conditions and to compare these data to historical and regional information. Historical and current nutrient concentrations were elevated throughout the watershed, in most cases above suggested criteria, and indicated that water quality of the river was and continues to be nutrient rich. A future reservoir at recent levels of water quality will likely be highly eutrophic, and anthropogenic influences will further stress this ecosystem and its water quality as the urban region expands.

    Batrachochytrium dendrobatidis (Bd), the cause of chytridiomycosis, is a pathogenic fungus that is found worldwide and is a major contributor to amphibian declines and extinctions. We report results of a comprehensive effort to assess the distribution and threat of Bd in one of the Earth's most important biodiversity hotspots, the Albertine Rift in central Africa. In herpetological surveys conducted between 2010 and 2014, 1018 skin swabs from 17 amphibian genera in 39 sites across the Albertine Rift were tested for Bd by PCR. Overall, 19.5% of amphibians tested positive from all sites combined. Skin tissue samples from 163 amphibians were examined histologically; of these two had superficial epidermal intracorneal fungal colonization and lesions consistent with the disease chytridiomycosis. One amphibian was found dead during the surveys, and all others encountered appeared healthy. We found no evidence for Bd-induced mortality events, a finding consistent with other studies. To gain a historical perspective about Bd in the Albertine Rift, skin swabs from 232 museum-archived amphibians collected as voucher specimens from 1925-1994 were tested for Bd. Of these, one sample was positive; an Itombwe River frog (Phrynobatrachus asper) collected in 1950 in the Itombwe highlands. This finding represents the earliest record of Bd in the Democratic Republic of Congo. We modeled the distribution of Bd in the Albertine Rift using MaxEnt software, and trained our model for improved predictability. Our model predicts that Bd is currently widespread across the Albertine Rift, with moderate habitat suitability extending into the lowlands. Under climatic modeling scenarios our model predicts that optimal habitat suitability of Bd will decrease causing a major range contraction of the fungus by 2080. Our baseline data and modeling predictions are important for comparative studies, especially if significant changes in amphibian health status or climactic conditions are encountered

    Full Text Available The encouragement of sustainable consumption and production (SCP in order to continuously improve the well-being of present and future generations is the most important goal stated in the European Union (EU Sustainable Development Strategy, which was renewed in 2006. The challenge for every company on the way to SCP is not only to use appropriate methods and measures to solve their specific sustainability problems, but, first of all, to select appropriate performance indicators and implement an effective sustainability performance evaluation system. It may be useful to apply an integrated indicator as a single comparable index, reducing the number of sustainability decision-making criteria that need to be considered. However, despite various approaches to create frameworks and methodologies for the development of integrated sustainability indicators that measure, monitor and assess the progress of an enterprise towards sustainability, there is still no comprehensive framework for integrated sustainability assessment of the overall company state on the basis of manufacturing processes, products/services as well as relationship with various stakeholders. An algorithm is here presented in respect of this demand. This algorithm offers methodical suggestions to assess the customers’ opinion about the presence of company’s environmental and social sustainability activities and initiatives, to identify and select most appropriate sustainability indicators, to determine their significance according to analytic hierarchy process (AHP, and to solve the most important sustainability problems in 3 aforementioned levels by adapting most suitable tools. The final suggestions are based on the values of 3 sub-indices of a new integrated index for the overall assessment of the SCP state in the company, ISCP.DOI: http://dx.doi.org/10.5755/j01.erem.71.3.11482

  10. United States panel presentations

    International Nuclear Information System (INIS)

    According to studies by the Department of Energy, toward the latter part of this decade, we will have to add five or six baseload plants, and in the period from 2000 to 205, we are going to need some sixty additional baseload plants. So in the next fifteen years we will need some sixty-five or seventy baseload plants. One can argue over the accuracy of those numbers, but tens of new baseload plants are going to be needed, and that means we are going to have to start the design of these plants in the next few years to get them online by the end of the century. I think there is going to be a change in attitude towards new plants. My view is that when the American public is faced with the decision of what kind of new energy source they need versus 'do I let the lights dim?', that nuclear power will be one of their choices. We will see as a result the revival of nuclear power - the water reactors in the near term, and I will leave for later discussion the question of whether we will use breeders and gas-cooled reactors for the longer term

  11. United States panel presentations

    International Nuclear Information System (INIS)

    I think, as a priority before we can move forward with new plants, from a public perception standpoint, we are going to have to do something credible about wastes. I am very optimistic now that the National Research Council has said that the existing waste disposal criteria and standards are not credible, that they are unattainable because technically we cannot prove that a technical scheme will continue to work far into the future. It is time for us to get back and figure out what we can demonstrate to be true in order to show people that the repository siting process we are about to go through is, in fact, credible. I think no new reactor design is going to be purchased unless the safety regulatory system is changed. I am not talking about design standardization here. I am talking about a basic review of all the rules and regulations in order to determine whether they are doing anything productive. The current set of rules and regulations is immense. Many of them are no longer relevant or current. That has to be changed rather dramatically. I think we are only treating the symptoms of our problems if we think that standardization, or one-step licensing, will solve them. The rules also apply after the plant starts up as well, and that is where those of us who operate nuclear power plants are now suffering. Clearly, one of the things that is obvious for the future of nuclear power is that we must maintain good operations. I think if you were to take a realistic look, in the next five or ten years, you would probably see more of an evolutionary design than a revolutionary design being used in actual practice. My sense is that if we continue to operate our plants well, public support will be there. Clearly we do not need any more Three Mile Islands to occur in this country

    The Department of Energy is supporting a number of programs directed at improving nuclear power's ability to compete by the mid 1990s in providing some of what will be urgently needed new baseload capacity, and at meeting both utility requirements and public goals. More specifically, we are co-funding demonstration by 1993 of the process for life extension of current nuclear plants. We are supporting the development of new ALWR designs which rely more on methods such as natural circulation, gravity, reduced power density, or the characteristics of materials, rather than engineered systems to provide safety. These designs will meet the criteria set forth in EPRI's Utility Requirements Documents. We have established a cost-sharing program to demonstrate the success of the nuclear plant standardization and licensing process by obtaining NRC certification by 1992 or 1993 of two evolutionary 1300MWe ALWR designs. We are also cost-sharing a program to certify by 1995 passively safe 600MWe ALWRs employing more natural safety features and modular construction. These programs will involve a rule-making hearing process. We are supporting the development and possible certification early in the next century of modular high temperature gas reactor and advanced liquid metal reactor plant designs. We are planning to demonstrate the early site approval licensing process through a cost-sharing arrangement with the private sector by 1995. In developing the National Energy Strategy, we are examining the issue of a fully satisfactory regulatory process, including the possibility of legislation codifying 10 CFR Part 52, limiting the possible delays associated with a potential second hearing and dealing with emergency planning issues before start of construction. We recently announced a restructured plan to develop a permanent waste repository by 2010. By 1995 we expect to have made significant progress in evaluating the suitability of Yucca Mountain. We expect to have selected a monitored retrievable storage site and submitted a license application to the NRC, pointing toward first operation of an MRS facility in 1998. Also on the waste front, we are beginning to study recycling of actinides in spent nuclear fuel to possibly benefit future long-term nuclear waste management. We will encourage and support an effective dialogue with the public on the benefits and risks of nuclear power relative to other alternatives

  13. Present state of reprocessing

    International Nuclear Information System (INIS)

    The operation of several reprocessing plants - industrial size and pilot plants - has made it possible to build up substantial experience in the processing of irradiated fuels. More than 28,000 tons of fuels from gas-graphite reactors were processed on an industrial basis in Britain and France. For the treatment of both metallic fuels and high burn-up UO2-fuels, a solvent extraction process is applied which is based on the Purex process with a TBP kerosene mixture as extractant. A shear-leach technique is used for the break-down of the bundle elements and dissolution of the uranium oxide in nitric acid. Mechanically agitated extractors and pulsed columns have proved to be reliable equipment. The products are uranyl nitrate and plutonium nitrate. Process chemicals are recycled to minimize the volume of radioactive waste and precautions are taken to prevent uncontrolled escape of radioactivity. The technical status will be described as well as experience from pilot operation. (orig.)

  14. Assessing the state-level consequences of global warming: Socio-economic and energy demand impacts

    International Nuclear Information System (INIS)

    The large body of research on climate change has begun to recognize a significant deficiency: the lack of analysis of the impact of climate change at a spatial level consistent with the anticipated occurrence of climate change. Climate change is likely to vary by region, while impact analysis has focused on much larger political units. Clearly, adaptation/mitigation strategies must be developed at a level consistent with political and policy-making processes. This paper specifically addresses this deficiency by identifying the potential socio-economic and energy demand consequences of climate change for subnational regions. This is accomplished via the development and application of a regional simultaneous equation, econometric simulation model that focuses on five states (Illinois, Indiana, Michigan, Ohio, and Wisconsin) in the Great Lakes region of the US. This paper presents a process for obtaining state-specific assessments of the consequences of climate change for the socio-economic system. As such, it provides an indication of which economic sectors are most sensitive to climate change for a specific state (Indiana), a set of initial mitigation/adaptation strategies for this state, and the results of testing these strategies in the policy analysis framework enabled by the model. In addition, the research demonstrates an effective methodology for assessing impacts and policy implications of climate change at a level consistent with policy making authority

    Grasslands cover the majority of the world's agricultural area, provide the feedstock for animal production, contribute to the economy of farms, and deliver a variety of ecological and societal services. Assessing responses of grassland ecosystems to climate change, in particular climate-related risks, is therefore an important step toward identifying adaptation options necessary to secure grassland functioning and productivity. Of particular concern are risks in relation to drought and extreme temperatures, on the one hand because grasslands are very sensitive to water stress, on the other hand also because global warming is expected to increase the occurrence and intensity of these events in many agricultural areas of the world. In this contribution we review findings of ongoing experimental and modelling activities that aim at examining the implications of climate extremes and climate change for grassland vegetation dynamics and herbage productivity. Data collected at the Jura foot in western Switzerland indicate that water scarcity and associated anomalous temperatures slowed plant development in relation to both the summer drought of 2003 as well as the spring drought of 2011, with decline in annual yields of up to 40%. Further effects of drought found from the analysis of recent field trials explicitly designed to study the effects of different water management regimes are changes in the functional composition and nutritive value of grasslands. Similar responses are disclosed by simulations with a process based grassland ecosystem model that was originally developed for the simulation of mixed grass/clover swards. Simulations driven with historical weather records from the Swiss Plateau suggest that drought and extreme temperature could represent one of the main reasons for the observed yield variability in productive systems. Simulations with climate change scenarios further reveal important changes in ecosystem dynamics for the current century. The results

  19. Anticipating the Future, Influencing the Present: Assessing the Societal Implications of Emerging Technologies

    Science.gov (United States)

    Michelson, Evan S.

    A growing challenge for the American policymaking system is to respond effectively to a wide range of interconnected, complex, long-term science and technology issues. Simultaneously, current approaches and institutions of governance are ill suited to address these multidimensional challenges. As the next generation of innovations in science and technology is arriving at an accelerating rate, the governance system is lagging behind. This realization leads to a vital overarching consideration that steers this study: What approaches are well suited to anticipate the longer-term societal implications of emerging technologies in the 21st Century? This study identifies and examines strategies for anticipating the longer-term societal implications of emerging technologies by way of a qualitative case study. It explores one area of technology (nanotechnology), in one particular governance system (the United States), and with a focus on one high profile non-governmental organization (NGO) involved in addressing a range of nanotechnology's societal and policy implications: the Project on Emerging Nanotechnologies (PEN). Based at the Woodrow Wilson International Center for Scholars, PEN's goal was to ensure "that as nanotechnologies advance, possible risks are minimized, public and consumer engagement remains strong, and the potential benefits of these new technologies are realized." The conceptual framework of anticipatory governance guides the research, which offers a real-world example about how anticipatory governance applies in the nongovernmental sector and shows how this idea links to broader theoretical debates about the policymaking process. The study's main conclusion is that PEN utilized a set of interconnected strategies related to advancing foresight, operating in a boundary-spanning role, and promoting communications and public engagement in its attempt to influence, anticipate, and shape the societal implications of emerging technologies. The findings are

The present study demonstrates the value of collecting data directly from deliverers of home visiting programs across a state. This study was conducted in response to the Patient Protection and Affordable Care Act, which requires states to conduct a needs assessment of home visiting programs for pregnant women and young children to receive federal funding. In this paper, we provide a descriptive analysis of a needs assessment of home visiting programs in Ohio. Methods All programs in the state that met the federal definition of home visiting were included in this study. Program staff completed a web-based survey with open- and close-ended questions covering program management, content, goals, and characteristics of the families served. Results Consistent with the research literature, program representatives reported great diversity with regard to program management, reach, eligibility, goals, content, and services delivered, yet consistently conveyed great need for home visiting services across the state. Conclusions Results demonstrate quantitative and qualitative assessments of need have direct implications for public policy. Given the lack of consistency highlighted in Ohio, other states are encouraged to conduct a similar needs assessment to facilitate cross-program and cross-state comparisons. Data could be used to outline a capacity-building and technical assistance agenda to ensure states can effectively meet the need for home visiting in their state. PMID:26576591

  1. Special RADMIL report. Assessment of the past and present implications of radioactive contamination of Lancashire

    The county of Lancashire in the United Kingdom has a unique relationship with the nuclear industry in respect of the number of nuclear facilities within or close to its boundaries. This special Radiation Monitoring in Lancashire (RADMIL) report collates data collected from 1976 to 1994 to provide a dose reconstruction for that period. It is shown that the radiation exposure of the population of Lancashire has decreased over the past twenty years. This has been due largely to a decrease in the authorised discharges from the facilities at Sellafield. Despite the fact that the advisory public dose limits have been reduced fivefold over the period, the dose to the most exposed groups has been consistently below those limits. Present contamination of the Lancashire environment is much reduced by comparison with earlier years. The accumulated effect of past discharges will mean that little further improvement can be expected, however. Similarly, dose levels to the populations are also expected to remain steady unless discharges increase again. This data compilation will form a baseline against which RADMIL can compare the results of future monitoring. (17 figures, 38 tables, 182 references) (UK).

  3. Risk assessment of landfill disposal sites - State of the art

    International Nuclear Information System (INIS)

    A risk assessment process can assist in drawing a cost-effective compromise between economic and environmental costs, thereby assuring that the philosophy of 'sustainable development' is adhered to. Nowadays risk analysis is in wide use to effectively manage environmental issues. Risk assessment is also applied to other subjects including health and safety, food, finance, ecology and epidemiology. The literature review of environmental risk assessments in general and risk assessment approaches particularly regarding landfill disposal sites undertaken by the authors, reveals that an integrated risk assessment methodology for landfill gas, leachate or degraded waste does not exist. A range of knowledge gaps is discovered in the literature reviewed to date. From the perspective of landfill leachate, this paper identifies the extent to which various risk analysis aspects are absent in the existing approaches

    Depression and negative symptoms can be difficult to distinguish in schizophrenia. Assessments for negative symptoms usually account for the longitudinal nature of these symptoms, whereas instruments available to measure depression mainly assess current or recent symptoms. This construct difference may confound comparison of depressive and negative symptoms in schizophrenia because both domains may have trait-like aspects.

    Full Text Available Abstract This paper presents a novel methodology in which the Unified Parkinson's Disease Rating Scale (UPDRS data processed with a rule-based decision algorithm is used to predict the state of the Parkinson's Disease patients. The research was carried out to investigate whether the advancement of the Parkinson's Disease can be automatically assessed. For this purpose, past and current UPDRS data from 47 subjects were examined. The results show that, among other classifiers, the rough set-based decision algorithm turned out to be most suitable for such automatic assessment.

  8. Past, Present, and Future Sea Level Change Assessments of Storm Surge: A Case Study Using Hurricane Katrina

    2012-12-01

    Major Gulf hurricanes have a high probability of impacting the northern Gulf of Mexico, especially coastal Mississippi (Resio, 2007). Due to the wide and flat continental shelf, this area provides near-perfect geometry for high water levels under tropical cyclonic conditions. Further, it is generally agreed that global sea levels due to climate change will rise anywhere from 18 to 100 cm by the year 2100 (Donoghue, 2011, IPCC, 2007) with some projecting even higher. Further, it is recognized that coastal Mississippi is highly susceptible to a retreating shoreline from sea level rise coupled with predictions for less frequent, more intense tropical storms from an increase in sea surface temperature (SST) (Trenberth, 2005, Webster, et al., 2005). A fully-validated, state-of-the-art ADCIRC+UnSWAN hydrodynamic model of coastal Mississippi was utilized to simulate Hurricane Katrina with present day sea level conditions. Using present day as a base scenario, past and future sea level changes were simulated. A regression was performed at local tide gauges to estimate past and project future sea levels. Also, surface roughness (i.e. Manning's n and wind reduction factors) was adjusted to reflect past landcover conditions as well as estimate future landcover change. Here, past, present and future sea level scenarios are modeled using a dynamic approach, along with Hurricane Katrina, and compared to present dynamic responses to sea level rise. The dynamic results will be compared and contrasted with a simpler bathtub model (static) approach. It will be demonstrated that water levels do not change linearly with modeled sea level cases (i.e. a 50 cm rise in sea level will not result in an additional 50 cm of water level at a given location) and are highly variable to changes in local conditions (e.g. topography, bathymetry, and surface roughness). Further, nearshore wind-wave conditions are affected by changes in local sea level due to the changes in momentum transfer from the

  10. Earthquake Hazard and Risk Assessment based on Unified Scaling Law for Earthquakes: State of Gujarat, India

    Science.gov (United States)

    Nekrasova, Anastasia; Kossobokov, Vladimir; Parvez, Imtiyaz

    2016-04-01

    The Gujarat state of India is one of the most seismically active intercontinental regions of the world. Historically, it has experienced many damaging earthquakes including the devastating 1819 Rann of Kutch and 2001 Bhuj earthquakes. The effect of the later one is grossly underestimated by the Global Seismic Hazard Assessment Program (GSHAP). To assess a more adequate earthquake hazard for the state of Gujarat, we apply Unified Scaling Law for Earthquakes (USLE), which generalizes the Gutenberg-Richter recurrence relation taking into account naturally fractal distribution of earthquake loci. USLE has evident implications since any estimate of seismic hazard depends on the size of the territory considered and, therefore, may differ dramatically from the actual one when scaled down to the proportion of the area of interest (e.g. of a city) from the enveloping area of investigation. We cross compare the seismic hazard maps compiled for the same standard regular grid 0.2°×0.2° (i) in terms of design ground acceleration (DGA) based on the neo-deterministic approach, (ii) in terms of probabilistic exceedance of peak ground acceleration (PGA) by GSHAP, and (iii) the one resulted from the USLE application. Finally, we present the maps of seismic risks for the state of Gujarat integrating the obtained seismic hazard, population density based on 2011 census data, and a few model assumptions of vulnerability.

    2015-03-01

    Full Text Available Twenty water samples were obtained in Akungba Akoko, Ondo State, Nigeria in order to determine the groundwater quality in the area. Thirteen samples were obtained from hand-dug wells, two samples were obtained from a spring while the remaining five samples were collected from boreholes. These samples were subjected to both physical and chemical analyses with a view to comparing the results obtained with the World Health Organization’s (WHO standard for quality drinking water. The results of the physical parameters measured shows that the colour ranges from 5°H to 50°H, turbidity ranges from 2NTU to 40NTU and the electrical conductivity ranges from 2.2×102 mho/cm to 1.4×103 mho/cm. Chemical analysis results on the other hand show that all the samples have pH within the weakly acidic range except for sample HDW 3 that falls within the weakly alkaline range. Furthermore, the Total Dissolved Solids (TDS range from 154 to 980 mg/L while the Total Hardness of the water samples range from 24 to 280 mg/L. Ionic studies show that the Ca2+, Na+, K+ and Mg2+ occur in order of decreasing abundance in the samples with the concentrations ranging from 10 to 160 mg/L, 20 to 90 mg/L, 10 to 90 mg/L and 14 to 150 mg/L, respectively. The anions present in the water samples in order of decreasing abundance are HCO3-, Cl-, SO2-4 and NO-3 with their concentrations ranging from 44 to 292 mg/L, 10 to 77 mg/L, 0.01 to 50 mg/L and 0.01 to 4.0 mg/L, respectively. It has been shown that anthropogenic inputs can continually ruin the suitability of the water for safe drinking purpose. Therefore, the ability to quickly control the anthropogenic inputs to the groundwater system in Akungba Akoko area will assist in keeping the quality of groundwater in Akungba Akoko to be maintained.

    Major factors for desertification are soil deterioration phenomena such as decrease in the covering by plants, water erosion, weathering, and decrease of organic matter. The current state of desertification and the trend of soil conservation are introduced quoting the case of Niger, and the current state of facing the problem on the spot is introduced lastly. Increase of the population and tight situation of the utilization of land in such severe environment as unstable rainfalls and poor soil are the causes for the poor production basis. Another cause is farming of the extensive style even at present. Effective measures for soil conservation are the improvement of productivity and conservation by water harvesting and fertility management. However, self-help soil conservation by the inhabitants themselves is currently difficult because of the present state of the social economy. It is required that soil conservation is positioned in the overall development of farming village and is developed simultaneously with the improvement of the rate of self-supporting, securing of cash income, and improvement of living environment. 10 refs., 9 figs., 3 tabs.

  14. Nuclear Waste State-of-the-Art reports 2007. The responsibility of the present generation, and the freedom of the coming ones

    International Nuclear Information System (INIS)

    KASAM presents a report on the state of knowledge in the nuclear waste area every third year. The present report is number nine in this series, and is published as one main report (this one) accessible to the layman, and four sub-reports that go into more detail (These four reports are titled: 1. Final disposal of spent nuclear fuels - regulations and the roles of different stakeholders during the decision making; 2. Safety analysis of final disposal of nuclear waste - significance, development and challenges; 3. Time for final disposal of nuclear waste - society, technology and nature; 4. Risk perspective on final disposal of nuclear waste - Individuals, society and communication (all available at the KASAM homepage)) We hope that this main report will give an overall picture of our assessments from the first report in 1986 up until today. The development has outdated parts of the assessment, but a surprisingly large share is still relevant. Our aim is also to describe the development within which these assessments were done in order to contribute to a fundamental understanding of the complex of problem around the nuclear waste issue

  15. Seismic risk assessment and application in the central United States

    Science.gov (United States)

    Wang, Z.

    2011-01-01

    Seismic risk is a somewhat subjective, but important, concept in earthquake engineering and other related decision-making. Another important concept that is closely related to seismic risk is seismic hazard. Although seismic hazard and seismic risk have often been used interchangeably, they are fundamentally different: seismic hazard describes the natural phenomenon or physical property of an earthquake, whereas seismic risk describes the probability of loss or damage that could be caused by a seismic hazard. The distinction between seismic hazard and seismic risk is of practical significance because measures for seismic hazard mitigation may differ from those for seismic risk reduction. Seismic risk assessment is a complicated process and starts with seismic hazard assessment. Although probabilistic seismic hazard analysis (PSHA) is the most widely used method for seismic hazard assessment, recent studies have found that PSHA is not scientifically valid. Use of PSHA will lead to (1) artifact estimates of seismic risk, (2) misleading use of the annual probability of exccedance (i.e., the probability of exceedance in one year) as a frequency (per year), and (3) numerical creation of extremely high ground motion. An alternative approach, which is similar to those used for flood and wind hazard assessments, has been proposed. ?? 2011 ASCE.

    Acute myocardial infarction, caused by the rupture of vulnerable coronary plaques, is the leading cause of death worldwide. Collagen is the primary extracellular matrix macromolecule that imparts the mechanical stability to a plaque and its reduction causes plaque instability. Intracoronary polarization sensitive optical coherence tomography (PS-OCT) measures the polarization states of the backscattered light from the tissue to evaluate plaque birefringence, a material property that is elevated in proteins such as collagen with an ordered structure. Here we investigate the dependence of the PS-OCT parameters on the quantity of the plaque collagen and fiber architecture. In this study, coronary arterial segments from human cadaveric hearts were evaluated with intracoronary PS-OCT and compared with Histopathological assessment of collagen content and architecture from picrosirius-red (PSR) stained sections. PSR sections were visualized with circularly-polarized light microscopy to quantify collagen birefringence, and the additional assessment of color hue indicated fibril thickness. Due to the ordered architecture of thick collagen fibers, a positive correlation between PS-OCT retardation and quantity of thick collagen fibers (r=0.54, p=0.04), and similarly with the total collagen content (r=0.51, p=0.03) was observed. In contrast, there was no perceivable relationship between PS-OCT retardation and the presence of thin collagen fibers (r=0.08, p=0.07), suggesting that thin and disorganized collagen fiber architecture did not significantly contribute to the PS-OCT retardation. Further analysis will be performed to assess the relationship between PS-OCT retardation and collagen architecture based on immunohistochemical analysis of collagen type. These results suggest that intracoronary PS-OCT may open the opportunity to assess collagen architecture in addition total collagen content, potentially enabling an improved understanding of coronary plaque rupture.

    The objective of this study was to identify and assess opportunities for demonstration and large scale deployment of solar electric facilities in the southeast region and to define the technical, economic, and institutional factors that can contribute to an accelerated use of solar energy for electric power generation. Graphs and tables are presented indicating the solar resource potential, siting opportunities, energy generation and use, and socioeconomic factors of the region by state. Solar electric technologies considered include both central station and dispersed solar electric generating facilities. Central stations studied include solar thermal electric, wind, photovoltaic, ocean thermal gradient, and biomass; dispersed facilities include solar thermal total energy systems, wind, and photovoltaic. The value of solar electric facilities is determined in terms of the value of conventional facilities and the use of conventional fuels which the solar facilities can replace. Suitable cost and risk sharing mechanisms to accelerate the commercialization of solar electric technologies in the Southeast are identified. The major regulatory and legal factors which could impact on the commercialization of solar facilities are reviewed. The most important factors which affect market penetration are reviewed, ways to accelerate the implementation of these technologies are identified, and market entry paths are identified. Conclusions and recommendations are presented. (WHK)

  6. Transparency in risk assessments - Presenting the 'expectation value' of post-closure risks from radioactive waste repositories

    International Nuclear Information System (INIS)

    derived from site characterisation or laboratory experiments might be more suitably assessed through 'what-if' calculations outside the risk assessment. Transparency might be enhanced by a wide-ranging debate, involving developer, regulator and other stakeholders, about the types of low probability or speculative events and processes to be examined in this way. If there was a consensus view that a particular event or process of this nature should be given greater emphasis, steps might be taken to modify the safety case, and possibly the design of the facility. The developer would maintain a basis for proceeding, while stakeholders would have the assurance that a mechanism existed for addressing their concerns in the overall safety case presented to the regulator. The study also concluded that the uncertainties concerning future populations were likely to be too great for assessments of group risk to be useful in regulatory decision-making. Comparative analyses of group risk may however be beneficial in making and explaining design decisions

    Full Text Available Atmospheric mercury is a toxic air and water pollutant that is of significant concern because of its effects on human health and ecosystems. A mechanistic representation of the atmospheric mercury cycle is developed for the state-of-the-art global climate-chemistry model, CAM-Chem (Community Atmospheric Model with Chemistry. The model simulates the emission, transport, transformation and deposition of atmospheric mercury (Hg in three forms: elemental mercury (Hg(0, reactive mercury (Hg(II, and particulate mercury (PHg. Emissions of mercury include those from human, land, ocean, biomass burning and volcano related sources. Land emissions are calculated based on surface solar radiation flux and skin temperature. A simplified air–sea mercury exchange scheme is used to calculate emissions from the oceans. The chemistry mechanism includes the oxidation of Hg(0 in gaseous phase by ozone with temperature dependence, OH, H2O2 and chlorine. Aqueous chemistry includes both oxidation and reduction of Hg(0. Transport and deposition of mercury species are calculated through adapting the original formulations in CAM-Chem. The CAM-Chem model with mercury is driven by present meteorology to simulate the present mercury air quality during the 1999–2001 periods. The resulting surface concentrations of total gaseous mercury (TGM are then compared with the observations from worldwide sites. Simulated wet depositions of mercury over the continental United States are compared to the observations from 26 Mercury Deposition Network stations to test the wet deposition simulations. The evaluations of gaseous concentrations and wet deposition confirm a strong capability for the CAM-Chem mercury mechanism to simulate the atmospheric mercury cycle. The results also indicate that mercury pollution in East Asia and Southern Africa is very significant with TGM concentrations above 3.0 ng m−3. The comparison to wet deposition indicates that wet deposition patterns of

  9. Environmental assessments of alternative energy strategies in the United States

    International Nuclear Information System (INIS)

    The Regional Issues Identification and Assessment (RIIA) program is an evaluation of the regional impacts of future energy development. These studies are conducted for the Department of Energy. The impacts described in this paper for 1990 are based on a national energy projection (scenario) that assumes medium energy demand and fuel supply through 1990, but does not incorporate the policies of the 1978 National Energy Act. The RIIA study plan uses the predicted fuel mixes derived from the PIES scenario as a starting point for its analysis. County level patterns for utility, industry and mining activities for 1990 were then developed from the federal region totals. Energy sources addressed were coal, nuclear, oil, oil shale, gas, geothermal, hydroelectric, and solar. The impact of these county-level patterns of utility, industry, and mining activities on the air, water, and land resources of the country and on the socioeconomic and health and safety aspects of the nation's welfare are analyzed

  10. State of the Art and Trends in Wind Resource Assessment

    Directory of Open Access Journals (Sweden)

    Oliver Probst

    2010-06-01

    Full Text Available Given the significant rise of the utilization of wind energy the accurate assessment of the wind potential is becoming increasingly important. Direct applications of wind assessment techniques include the creation of wind maps on a local scale (typically 5 20 km and the micrositing of wind turbines, the estimation of vertical wind speed variations, prospecting on a regional scale (>100 km, estimation of the long-term wind resource at a given site, and forecasting. The measurement of wind speed and direction still widely relies on cup anemometers, though sonic anemometers are becoming increasingly popular. Moreover, remote sensing by Doppler techniques using the backscattering of either sonic beams (SODAR or light (LIDAR allowing for vertical profiling well beyond hub height are quickly moving into the mainstream. Local wind maps are based on the predicted modification of the regional wind flow pattern by the local atmospheric boundary layer which in turn depends on both topographic and roughness features and the measured wind rose obtained from one or several measurement towers within the boundaries of the planned development site. Initial models were based on linearized versions of the Navier-Stokes equations, whereas more recently full CFD models have been applied to wind farm micrositing. Linear models tend to perform well for terrain slopes lower than about 25% and have the advantage of short execution times. Long-term performance is frequently estimated from correlations with nearby reference stations with concurrent information and continuous time series over a period of at least 10 years. Simple methods consider only point-to-point linear correlations; more advanced methods like multiple regression techniques and methods based on the theory of distributions will be discussed. Both for early prospecting in regions where only scarce or unreliable reference information is available, wind flow modeling on a larger scale (mesoscale is becoming

    Climate change is likely to affect forests and the forest industry during the 21{sup st} century. Different processes in forest ecosystems and the forest sector are sensitive to climate and many different projects have been conducted, in which the scale of study varied from the individual leaf to the whole globe. Several attempts have been made to link impact models (e.g., ecological and socio-economic models), and to integrate them in national or regional climate impact assessment studies. However, integration of climate impact assessments for the forestry sector is still a relatively new issue on the research agenda. From November 10 to 13, 1999 the Postdam Institue for Climate Impact Research and the European Forest Institute organised a workshop in Wenddoche near Belzig (Germany) to bring together individuals and research groups from the currently developing research community, to provide a forum for the exchange of experience, and to stimulate further research collaboration. The workshop attracted 31 scientists from 12 countries, representing a wide range of disciplines covering ecophysiology, soils, forest ecology, growth and yield, silviculture, remote sensing, forest policy, and forest economics. Several presentations investigated possible impacts of climate change on forest growth and development. A second major topic was the carbon budget and the possible contribution of forestry to carbon dioxide mitigation. The third important focus was the application of economic models to estimate socio-economic consequences of changes in forest productivity and the linkage of ecological and economic models. Non-timber forest benefits were addressed in one regional impact assessment and in two national integrated assessments from the U.S. and Germany. The latter also included social components with the involvement of stakeholders and the decision making of forest owners under global change.

  13. A graphical editor for the presentation of technical components and their states at the COSY accelerator ring

    International Nuclear Information System (INIS)

    The graphical editor is written in the Language C and the command 'bild' calls it. The presentation of technical components at the COSY accelerator ring was realized by presentations which are offered by the program RB. These pictograms can only be loaded. The states of these components are realized by push-button editors from the Xr library. These buttons can be newly generated or loaded. By the graphical operations for instance connections or cables can be presented. An editor must perform functions by which such objects can be influenced. This is erasing or moving these objects. In the submenus for the pictograms, buttons, and in the submenu 'Zeichnen' corresponding items are implemented. Single lines or a line from a line chain can be rotated. In the graphical operations line chains, rectangles, circles, and circular arcs can be filled with the foreground color. In the graphical editor also for the foreground respectively background color one from eight different colors can be chosen. These colors are used by all following functions. These colors are also taken for the buttons, which are however not used permanently, but can be changed locally. (orig.)

    This report is a background report for the biosphere analysis of the SR-Site Safety Assessment. This work aims to describe the future development of the chemical conditions at Forsmark, based on the present chemical conditions at landscape level taking landscape development and climate cases into consideration. The results presented contribute to the overall understanding of the present and future chemistry in the Forsmark area, and specifically, to the understanding of the behaviour of some selected radionuclides in the surface system. The future development of the chemistry at the site is qualitatively discussed with focus on the interglacial within the next 10,000 years. The effects on the chemical environment of future climate cases as Global Warming and cold permafrost climates are also briefly discussed. The work is presented in two independent parts describing background radionuclide activities in the Forsmark area and the distribution and behaviour of a large number of stable elements in the landscape. In a concluding section, implications of the future chemical environment of a selection of radionuclides important in the Safety Assessment are discussed based on the knowledge of stable elements. The broad range of elements studied show that there are general and expected patterns for the distribution and behaviour in the landscape of different groups of elements. Mass balances reveal major sources and sinks, pool estimations show where elements are accumulated in the landscape and estimations of time-scales give indications of the potential future development. This general knowledge is transferred to radionuclides not measured in order to estimate their behaviour and distribution in the landscape. It could be concluded that the future development of the chemical environment in the Forsmark area might affect element specific parameters used in de radionuclide model in different directions depending on element. The alternative climate cases, Global Warming

  16. Response-time evidence for mixed memory states in a sequential-presentation change-detection task.

    2016-02-01

    Response-time (RT) and choice-probability data were obtained in a rapid visual sequential-presentation change-detection task in which memory set size, study-test lag, and objective change probabilities were manipulated. False "change" judgments increased dramatically with increasing lag, consistent with the idea that study items with long lags were ejected from a discrete-slots buffer. Error RTs were nearly invariant with set size and lag, consistent with the idea that the errors were produced by a stimulus-independent guessing process. The patterns of error and RT data could not be explained in terms of encoding limitations, but were consistent with the hypothesis that long retention lags produced a zero-stimulus-information state that required guessing. Formal modeling of the change-detection RT and error data pointed toward a hybrid model of visual working memory. The hybrid model assumed mixed states involving a combination of memory and guessing, but with higher memory resolution for items with shorter retention lags. The work raises new questions concerning the nature of the memory representations that are produced across the closely related tasks of change detection and visual memory search. PMID:26706291

    In support of the U.S. Department of Energy (DOE) Wind and Water Power Technologies Office (WWPTO) goals, researchers from DOE's National Renewable Energy Laboratory (NREL), National Wind Technology Center (NWTC) are investigating the Distributed Wind Resource Assessment (DWRA) process, which includes pre-construction energy estimation as well as turbine site suitability assessment. DWRA can have a direct impact on the Wind Program goals of maximizing stakeholder confidence in turbine performance and safety as well as reducing the levelized cost of energy (LCOE). One of the major components of the LCOE equation is annual energy production. DWRA improvements can maximize the annual energy production, thereby lowering the overall LCOE and improving stakeholder confidence in the distributed wind technology sector by providing more accurate predictions of power production. Over the long term, one of the most significant benefits of a more defined DWRA process could be new turbine designs, tuned to site-specific characteristics that will help the distributed wind industry follow a similar trajectory to the low-wind-speed designs in the utility-scale industry sector. By understanding the wind resource better, the industry could install larger rotors, capture more energy, and as a result, increase deployment while lowering the LCOE. a direct impact on the Wind Program goals of maximizing stakeholder confidence in turbine performance and safety as well as reducing the levelized cost of energy (LCOE).

    Failure mechanisms of power transformers are complex and uncertain; it is difficult to determine index weights of insulation state.Therefore,it is a challenge to acquire an accurate assessment of insulation state of power transformers.In this paper,an assessing strategy for transformer insulation is proposed base on part-division of transformer and a comprehensive weight determination method.An index system of transformer is established on the basis of part-division of transformer.Each index's weight is consisted of two parts,the constant weight and the variable weight,which are determined by improved analytic hierarchy process (AHP) and entropy method respectively.After categorizing insulation state into four levels and standardizing assessing indexes,a Cauchy membership function is forged,and a fuzzy algorithm is employed to simulate the uncertainty of the insulation state.Finally,a confidence criterion is employed to perform part-division based condition assessment of transformer.Case studies reveal that the proposed assessing strategy method is effective,convenient,and practical; with the new strategy,potential failures of transformers can be forecasted and insulation state of transformer parts can also be assessed.Furthermore,the assessing results can be used to guide condition-based maintenance.

    1992-03-01

    Hoping the reader will not find the title overly pompous, we offer a brief and decidedly informal view of the state of the edge detection art, as we see it, in early 1992. We make no claim to clairvoyance, nor even to being especially insightful. But we have looked over the recent literature and made some attempt to evaluate where we are as a community with respect to this most ubiquitous problem and where we should be headed. We also briefly summarize the work of this session and our own recent contributions to compare the spectrum of philosophies represented to the community at large. This paper should be taken in the spirit in which it was written, which is to say not too seriously. Our aim is by no means frivolous, but we did try to have a little fun while dabbling as futurists. The ultimate goal of this paper is to stimulate some interesting interchange not so much on the `how to' of edge detection as on the `what next.'

    International Nuclear Information System (INIS)

    This paper presents a brief review and evaluation of the analytical methods, design methods, and design standards used in the seismic design of nuclear power plants with emphasis on US practice. Three major areas were investigated: a) soils, siting, and seismic ground motion specification, b) soil-structure interaction, c) the response of major nuclear power plant structures and components. The purpose of this review and evaluation program was to prepare an independent assessment of the state-of-the-art of the seismic design of nuclear power plants and to identify seismic analysis and design research areas meriting support by the nuclear power industry. Criteria used for evaluating the relative importance of alternative research areas included the potential research impact on nuclear power plant siting, design, construction, cost, safety, licensing, and regulation.

    The vermicompost produced from flower waste inoculated with biofertilizers was subjected to compost maturity test: (i) physicochemical method (pH, OC, TN, C:N); (ii) solid state spectroscopic analysis (FTIR and (13)C CPMAS NMR); and (iii) plant bioassay (germination index). The pH of vermicompost was decreased toward neutral, C:N ratio vermicomposts result shows reduction of complex organic materials into simple minerals which indicates the maturity of the experimental vermicompost product than the control. The increased aliphatic portion incorporated with flower residues may be due to the synthesis of alkyl, O-alkyl, and COO groups by the microbes present in the gut of earthworm. Plant bioassays are considered the most conventional assessment of compost maturity analysis, and subsequently, it shows the effect of vermicompost maturity on the germination index of Vigna mungo .

    The United States town of Aurora, Missouri, USA, stockpiled lead (Pb) and zinc (Zn) mining wastes from the early to mid-1900s in the form of chat piles. Clean-up actions were undertaken at intervals in subsequent years including land leveling and removal of chat. This study assessed the current state of contamination by identifying areas where metals are present at toxic levels. For this purpose, stream sediment samples (N = 100) were collected over a 9 × 12 km area in and around Aurora. Their content of cadmium (Cd), Pb, and Zn were measured, and concentration maps were generated using ArcGIS to categorize affected areas. Metal concentrations varied over a wide range of values with the overall highest values observed in the north-northeast part of Aurora where abundant chat piles had been present. Comparison between observed concentrations and sediment-quality guidelines put the contaminated areas mentioned are above-toxic levels for Cd, Pb and Zn. In contrast, levels in rural areas and the southern part of Aurora were at background levels, thus posing no threat to aquatic habitats. The fact that contamination is constrained to a relatively small area can be advantageously used to implement further remediation and, by doing so, to help protect the underlying karst aquifer.

    Effective and efficient reduction of natural hazard risks requires a thorough understanding of the costs of natural hazards in order to develop sustainable risk management strategies. The current methods that assess the costs of different natural hazards employ a diversity of terminologies and approaches for different hazards and impacted sectors. This makes it difficult to arrive at robust, comprehensive and comparable cost figures. The CONHAZ (Costs of Natural Hazards) project aimed to compile and synthesise current knowledge on cost assessment methods in order to strengthen the role of cost assessments in the development of integrated natural hazard management and adaptation planning. In order to achieve this, CONHAZ has adopted a comprehensive approach, considering natural hazards ranging from droughts, floods and coastal hazards to Alpine hazards, as well as different impacted sectors and cost types. Its specific objectives have been 1) to compile the state-of-the-art methods for cost assessment; 2) to analyse and assess these methods in terms of technical aspects, as well as terminology, data quality and availability, and research gaps; and 3) to synthesise resulting knowledge into recommendations and to identify further research needs. This presentation summarises the main results of CONHAZ. CONHAZ differentiates between direct tangible damages, losses due to business interruption, indirect damages, intangible effects, and costs of risk mitigation. It is shown that the main focus of cost assessment methods and their application in practice is on direct costs, while existing methods for assessing intangible and indirect effects are rather rarely applied and methods for assessing indirect effects often cannot be used on the scale of interest (e.g. the regional scale). Furthermore, methods often focus on single sectors and/or hazards, and only very few are able to reflect several sectors or multiple hazards. Process understanding and its use in cost assessment

    The use of LANDSAT for water resources applications in U.S. state demonstration projects is reviewed. The most common single application undertaken between 1976 and 1981 was found to be water condition assessment. The majority of projects, however, fell into the general category of watershed hydrology. Some of the states are attempting to use LANDSAT data in an operational mode for water quality assessment. Two of these state projects from Vermont and Wisconsin are described in brief. The basic information requirements of Section 314 of the U.S. Pollution Control Act are given with the type of input LANDSAT data could potentially provide toward those requirements. Surveys were performed to determine: (1) how its states were responding in 1980 to 1981 to the federal and state water quality laws; and (2) the status of LANDSAT analysis capabilities of each state.

    2015-01-01

    Full Text Available Background: In India, approximately 40,000 new cases of cancer in children are diagnosed each year. However, there are no good studies analyzing their nutritional status. Also, since accurate and sensitive nutritional assessment is critical for optimal clinical outcomes through timely remediation of malnutrition, it is important to assess the relative sensitivity and feasibility of commonly used nutritional screening tools. Methods: This observational study analyzed height/length (cm, weight (kg, mid-upper arm circumference (MUAC, triceps skinfold thickness (TSFT as well as their Z-scores or percentiles, albumin levels and history of weight loss at diagnosis in children aged 2–15 years being treated for cancer between November 2008 to December 2013. Body mass index (BMI and arm muscle circumference (AMC were calculated respectively from height and weight, and MUAC and TSFT. Results: A total of 1693 new patients were enrolled; 1187 had all anthropometric measurements performed. The prevalence of malnutrition was 38%, 57%, 76%, 69% and 81% on the basis of BMI, TSFT, MUAC, AMC, and arm TSFT + MUAC respectively with the highest prevalence in solid abdominal tumours. Addition of BMI and serum albumin to arm anthropometry increased the proportion classified as severely nutritionally depleted by a mere 2% & 1.5% respectively. Positive history of significant weight loss additionally identified 16.5% at nutritional risk over arm anthropometry. Conclusions: The prevalence of malnutrition in Indian children with cancer at presentation is very high ranging from 40% and 80% depending on the method used for assessment, being higher with MUAC and lowest with BMI. Either MUAC alone or TSFT + MUAC (wherever feasible should be used for screening for malnutrition in children with cancer at diagnosis to plan timely nutritional interventions, reduce the treatment-related morbidity and optimise their chance of long-term cure.

    2016-03-01

    Incomplete excision of tumour margins is a major issue in breast-conserving surgery. Currently 20 - 60% of cases require a second surgical procedure required as a result of cancer recurrence. A number of techniques have been proposed to assess margin status, including frozen section analysis and imprint cytology. However, the recurrence rate after using these techniques remains very high. Over the last several years, our group has been developing optical coherence elastography (OCE) as a tool for the intraoperative assessment of tumour margins in breast cancer. We have reported a feasibility study on 65 ex vivo samples from patients undergoing mastectomy or wide local excision demonstrates the potential of OCE in differentiating benign from malignant tissue. In this study, malignant tissue was readily distinguished from surrounding relative tissue by a distinctive heterogeneous pattern in micro-elastograms. To date the largest field of view for a micro-elastogram is 20 x 20mm, however, lumpectomy samples are typically ~50 x 50 x 30mm. For OCE to progress as a useful clinical tool, elastograms must be acquired over larger areas to allow a greater portion of the surface area of lumpectomies to be assessed. Here, we propose a wide-field OCE scanner that utilizes a piezoelectric transducer with an internal diameter of 65mm. In this approach partially overlapped elastograms are stitched together forming a mosaic with overall dimensions of 50 x 50mm in a total acquisition time of 15 - 30 minutes. We present results using this approach on both tissue-mimicking phantoms and tissue, and discuss prospects for shorter acquisitions times.

    Full Text Available Abstract Background Screening for mental disorders among disability claimants is important, since mental disorders seem to be seriously under-recognized in this population. However, performance of potentially suitable scales is unknown. We aimed to evaluate the psychometric properties of three scales, the 10- and 6-item Kessler Psychological Distress Scale (K10, K6 and the 12-item General Health Questionnaire (GHQ-12, to predict present state mental disorders, classified according to the Diagnostic and Statistical Manual of Mental Disorders, 4thEdition (DSM-IV among disability claimants. Methods All scales were completed by a representative sample of persons claiming disability benefit after two years sickness absence (n=293. All diagnoses, both somatic and mental, were included. The gold standard was the Composite International Diagnostic Interview (CIDI 3.0 to diagnose present state DSM-IV disorder. Cronbach’s α, sensitivity, specificity, positive (PPV and negative predictive values (NPV, and the areas under the Receiver Operating Characteristic curve (AUC were calculated. Results Cronbach’s alpha’s were 0.919 (K10, 0.882 (K6 and 0.906 (GHQ-12. The optimal cut-off scores were 24 (K10, 14 ( K6 and 20 (GHQ-12. The PPV and the NPV for the optimal cut point of the K10 was 0.53 and 0.89, for the K6 0.51 and 0.87, and for the GHQ-12 0.50 and 0.82. The AUC’s for 30-day cases were 0.806 (K10; 95% CI 0.749-0.862, 0.796 (K6; 95% CI 0.737-0.854 and 0.695 (GHQ-12; 95% CI 0.626-0.765. Conclusions The K10 and K6 are reliable and valid scales to screen for present state DSM-IV mental disorder. The optimal cut-off scores are 24 (K10 and 14 (K6. The GHQ-12 (optimal cut-off score: 20 is outperformed by the K10 and K6, which are to be preferred above the GHQ-12. The scores on separate items of the K10 and K6 can be used in disability assessment settings as an agenda for an in-depth follow-up clinical interview to ascertain the presence of present state

    Full Text Available This article discusses the problem of user identification and psychophysiological state assessment while writing a signature using a graphics tablet. The solution of the problem includes the creation of templates containing handwriting signature features simultaneously with the hidden registration of physiological parameters of a person being tested. Heart rate variability description in the different time points is used as a physiological parameter. As a result, a signature template is automatically generated for psychophysiological states of an identified person. The problem of user identification and psychophysiological state assessment is solved depending on the registered value of a physiological parameter.

  15. Assessment of present day geomorphological dynamics to decipher landscape evolution around the Paleolithic sites of Melka Kunture, Ethiopia

    2014-05-01

    The area of Melka Kunture (central Ethiopia) is one of the most important clusters of Paleolithic sites in Eastern Africa. The archaeological record spans from c. 1.7 Ma onwards, with a number of stratified occurrences of Oldowan, Acheulean, Middle Stone Age and Late Stone Age industries, together with faunal remains and human fossils. However, the archaeological sites are endangered by flooding and soil erosion. The main excavation area lies close to the convergence of the Awash river with the Atabella river, one of the main tributaries of the upper Awash catchment. In the semi-arid Ethiopian highlands, gully networks develop especially in the vicinity of the active and inactive river meanders. Various erosion processes are linked to specific driving factors such as the rainfall regime, the land use/cover changes and vertic soils with a specific hydrological behaviour. It was documented in the field and by previous research that the origin of most of the man made erosion channels is due to animal pathways and car tracks. However, paleolandscape features increase the general erosion risk. Former wetland areas and deposition zones are particularly affected by soil erosion processes. Hence, the spatial distribution and characteristics of present day geomorphic processes also reveal information on the paleolandscape. In order to assess landscape evolution and present day geomorphologic dynamics, we mapped the geomorphology describing in detail the present-day slope processes at a 10.000 scale. We performed a detailed terrain analysis based on high resolution DEMs such as SRTM-X with 25m resolution and ALOS/PRISM with 10m resolution to characterize the main erosion processes and surface runoff dynamics. The latter ones are simulated using a Soil Conservation Service Curve Number method. Landuse was delineated for a larger area using ASTER 25m multispectral data. Finally, using calibrated topographic indices and a simple hydrological model we were able to detect and

  16. Dynamic availability assessment and optimal component design of multi-state weighted k-out-of-n systems

    International Nuclear Information System (INIS)

    Availability/reliability is a main feature of design and operation of all engineering systems. Recently, availability evaluation of multi-state systems with different structures is at the center of attention due to the wide applications in engineering. In this paper, a dynamic model is developed for the availability assessment of multi-state weighted k-out-of-n systems. Then, in a design optimization problem, the availability and capacity for the components of such systems are optimized by genetic algorithm. In the dynamic model, the probabilities and capacities of components in different states are allowed to be changed over time. For availability assessment, universal generating function and Markov process are adopted. Application of the proposed model is illustrated using a real-world marine transportation system in order to evaluate and compare the presented optimization problems in assessing system availability. - Highlights: • A dynamic availability model is developed for multi-state weighted k-out-of-n systems. • Optimization problems for the design of multi-state weighted k-out-of-n systems are formulized based on the dynamic availability model. • Dynamic optimal design is not necessarily only one best solution during the time

    1,3-Propanediol and 2,3-butanediol are two promising chemicals which have a wide range of applications and can be biologically produced. The separation of these diols from fermentation broth makes more than 50% of the total costs in their microbial production. This review summarizes the present state of methods studied for the recovery and purification of biologically produced diols, with particular emphasis on 1,3-propoanediol. Previous studies on the separation of 1,3-propanediol primarily include evaporation, distillation, membrane filtration, pervaporation, ion exchange chromatography, liquid-liquid extraction, and reactive extraction. Main methods for the recovery of 2,3-butanediol include steam stripping, pervaporation, and solvent extraction. No single method has proved to be simple and efficient, and improvements are especially needed with regard to yield, purity, and energy consumption. Perspectives for an improved downstream processing of biologically produced diols, especially 1,3-propanediol are discussed based on our own experience and recent work. It is argued that separation technologies such as aqueous two-phase extraction with short chain alcohols, pervaporation, reverse osmosis, and in situ extractive or pervaporative fermentations deserve more attention in the future.

    Hirudinea is a small and ecologically important group of aquatic organisms. However, up to date, the leech fauna of Kazakhstan is poorly studied. The presence of large under-collected areas, such as the Upper Irtysh basin, makes biodiversity studies concerning these invertebrates from Kazakhstan relevant. In this paper, the latest information on species diversity of the freshwater hirudofauna of the Upper Irtysh cascade of water reservoirs, the Kazakhstan part of Irtysh River, is presented. It includes 10 free-living and parasitic species, of which 7 and 9 inhabit the Shulbinsk and the Bukhtarma reservoirs, respectively. These species belong to 2 orders, 3 families and 6 genera. The faunal list highlights four potentially new morphological species (Alboglossiphonia sp., Erpobdella sp., Piscicola sp. 1 and Piscicola sp. 2). Besides them, another three species Erpobdella vilnensis, Helobdella stagnalis and Theromyzon tessulatum recorded for the first time in the area. The exact systematic position is stated for all leech taxa. Each species from the list accompanied with information on taxonomic synonymy, data on its geographic distribution, and brief summary of morphological and ecological characteristics. PMID:27408572

    The mining operation game SIMBERG (SIMBERG - Simulation of Mining-Technical/-Economical Operation Processes for a Hard Coal Mine) has been introduced for the development of the upcoming junior management members. The general aim of the decision taking training persued by this game lies in the improvement of the decision taking capabilities and the increase of the decision taking willingness. The existing simulation model facilitates the representation of complex decision taking situations with links between technical-organisational and economical management responsability, between strategical and tactical management tasks in hierarchically different horizontal and vertical management positions. The education-oriented application for either advanced students or upcoming junior executives in advaced or operational management courses is made possible by the present state of development of the simulation model. The computer-supported planning game exercise based on a consequent data base concept is available in different languages: German, English, Polish, Chinese and Turkish. Further developments of the SIMBERG Model concern - a quantitative model extension and qualitative model up-dating for the preparation of applying the planning game technique to a real mining operation planning situation and - an extended inclusion of 'decision taking tools': Special analysis for operations research applications, information aquisition systems as well as decision supporting, specific mining expert systems.

    2016-03-01

    In this work the effects of incident intensity and effective camera dynamic range on image acquisition of both frozen and time-averaged dynamic speckle patterns, and their effects on laser speckle contrast imaging are addressed. A nematic liquid crystal, phase-only, spatial light modulator (SLM) was employed to generate laser speckle in a controlled and repeatable fashion. By addressing the calculated spatial contrast of frozen and time-averaged dynamic speckle patterns imaged across a wide range of intensities, we present a description of optimum intensity characteristics that should be observed when using LSCI. The results indicate the importance of assessing the intensity of the signal quantized by the camera in LSCI. By analyzing intensity PDF's during image acquisition of speckle patterns used in LSCI, an optimum incident intensity can be detected when a single, polarized speckle frame displays the first order statistics characteristic of fully developed speckle. Our results indicate that there is a range of laser power densities where the ensuing imaged speckle exhibit optimum sensitivity to flow as well as relatively constant calculated contrast values. It is clear that at high intensities, high frequency information is lost due to camera saturation, resulting in a decrease in contrast. When imaging speckle at low intensity, there is a risk for loss of data during the digital quantization process. The results are presented in a generalized fashion, so they should be applicable to any LSCI system, regardless of incident laser power or camera depth.

  4. Life cycle assessment of renewables: present issues, future outlook and implications for the calculation of external costs

    International Nuclear Information System (INIS)

    In principle, Life Cycle Assessment (LCA) is certainly appropriate for estimating external costs of renewables, since major environmental impacts of the latter are generated in phases of the life cycle other than use. In practice however, several issues still remain. They are related to the availability and quality of Life Cycle Inventory (LCI) data, to the frit technological development of renewable energy technologies (RET), to the existence of many different applications of the latter and to a strong dependency on local conditions. Moreover, a 'static' picture of present technologies is not enough for policy indications. Therefore some kind of dynamic LCA is needed. These LCA issues are reflected in the calculation of external costs. First, the paper discusses these issues on the examples of two main technologies, namely photovoltaic (PV) and wind. Second, it discusses the results of ExternE for these two specific technologies and gives an outlook for the future. Future needs for a better use of LCA as a support tool for the calcination of external costs are identified. Finally, a new research project funded by the European Commission focused on LCI of renewables is briefly introduced and presented. (author)

    Air pollutants pose a risk to forest health and vitality in the United States. Here we present the major findings from a national scale air pollution assessment that is part of the United States' 2003 Report on Sustainable Forests. We examine trends and the percent forest subjected to specific levels of ozone and wet deposition of sulfate, nitrate, and ammonium. Results are reported by Resource Planning Act (RPA) reporting region and integrated by forest type using multivariate clustering. Estimates of sulfate deposition for forested areas had decreasing trends (1994-2000) across RPA regions that were statistically significant for North and South RPA regions. Nitrate deposition rates were relatively constant for the 1994 to 2000 period, but the South RPA region had a statistically decreasing trend. The North and South RPA regions experienced the highest ammonium deposition rates and showed slightly decreasing trends. Ozone concentrations were highest in portions of the Pacific Coast RPA region and relatively high across much of the South RPA region. Both the South and Rocky Mountain RPA regions had an increasing trend in ozone exposure. Ozone-induced foliar injury to sensitive species was recorded in all regions except for the Rocky Mountain region. The multivariate analysis showed that the oak-hickory and loblolly-shortleaf pine forest types were generally exposed to more air pollution than other forest types, and the redwood, western white pine, and larch forest types were generally exposed to less. These findings offer a new approach to national air pollution assessments and are intended to help focus research and planning initiatives related to air pollution and forest health. PMID:15195820

  7. Hawaii Geothermal Resource Assessment Program: western state cooperative direct heat resource assessment, Phase I. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1978-01-01

    A regional geothermal resource assessment has been conducted for the major islands in the Hawaiian chain. The assessment was made through the compilation and evaluation of the readily accessible geological, geochemical, and geophysical data for the Hawaiian archipelago which has been acquired during the last two decades. The geologic criteria used in the identification of possible geothermal reservoirs were: age and location of most recent volcanism on the island and the geologic structure of each island. The geochemical anomalies used as traces for geothermally altered ground water were: elevated silica concentrations and elevated chloride/magnesium ion ratios. Geophysical data used to identify subsurface structure which may have geothermal potential were: aeromagnetic anomalies, gravity anomalies, and higher than normal well and basal spring discharge temperatures. Geophysical and geochemical anomalies which may be the result of subsurface thermal effects have been identified on the islands of Hawaii, Maui, Molokai and Oahu.

  8. On Birnbaum importance assessment for aging multi-state system under minimal repair by using the Lz-transform method

    International Nuclear Information System (INIS)

    This paper considers a reliability importance evaluation for components in an aging multi-state system. In practical reliability engineering a “curse of dimensionality” (the large number of states that should be analyzed for a multi-state system model) is a main obstacle for importance assessment. In order to challenge the problem, this paper proposes a new method that is based on an LZ-transform of the discrete-state continuous-time Markov process and on Ushakov's Universal Generating Operator. The paper shows that the proposed method can drastically reduce a computational burden. In order to illustrate the method, a solution of a real world problem is presented as a numerical example. - Highlights: • Aging multi-state system under minimal repair is studied. • A new method for Birnbaum importance assessment is developed. • The method is based on the LZ-transform. • The proposed method provides a drastic reduction of computation burden. • Numerical example is presented in order to illustrate the method

  9. A novel manifold–manifold distance index applied to looseness state assessment of viscoelastic sandwich structures

    International Nuclear Information System (INIS)

    Viscoelastic sandwich structures (VSS) are widely used in mechanical equipment; their state assessment is necessary to detect structural states and to keep equipment running with high reliability. This paper proposes a novel manifold–manifold distance-based assessment (M2DBA) method for assessing the looseness state in VSSs. In the M2DBA method, a manifold–manifold distance is viewed as a health index. To design the index, response signals from the structure are firstly acquired by condition monitoring technology and a Hankel matrix is constructed by using the response signals to describe state patterns of the VSS. Thereafter, a subspace analysis method, that is, principal component analysis (PCA), is performed to extract the condition subspace hidden in the Hankel matrix. From the subspace, pattern changes in dynamic structural properties are characterized. Further, a Grassmann manifold (GM) is formed by organizing a set of subspaces. The manifold is mapped to a reproducing kernel Hilbert space (RKHS), where support vector data description (SVDD) is used to model the manifold as a hypersphere. Finally, a health index is defined as the cosine of the angle between the hypersphere centers corresponding to the structural baseline state and the looseness state. The defined health index contains similarity information existing in the two structural states, so structural looseness states can be effectively identified. Moreover, the health index is derived by analysis of the global properties of subspace sets, which is different from traditional subspace analysis methods. The effectiveness of the health index for state assessment is validated by test data collected from a VSS subjected to different degrees of looseness. The results show that the health index is a very effective metric for detecting the occurrence and extension of structural looseness. Comparison results indicate that the defined index outperforms some existing state-of-the-art ones. (papers)

  10. The history, development and the present status of the radon measurement programme in the United States of America

    International Nuclear Information System (INIS)

    The US radon measurement programme began in the late 1950's by the US Public Health Service in Colorado, New Mexico and Utah during the uranium frenzy. After the 1967 Congressional Hearings on the working conditions in uranium mines, the US Atomic Energy Commission (AEC) was asked to conduct studies in active uranium mines to assess the exposure of the miners on the Colorado Plateau and in New Mexico. From 1967 to 1972, the Health and Safety Laboratory of the US AEC in New York investigated more than 20 uranium mines for radon and radon decay product concentrations and particle size in 4 large uranium mines in New Mexico. In 1970, the US Environmental Protection Agency (EPA) was established and took over some of the AEC radon measurement activities. Between 1975 and 1978, the Environmental Measurements Laboratory of the US Department of Energy conducted the first detailed indoor radon survey in the USA. Later in 1984, the very high concentrations of radon found in Pennsylvania homes set the wheels in motion and gave birth to the US Radon Industry. The US EPA expanded its involvement in radon issues and assumed an active role by establishing the National Radon Proficiency Program to evaluate the effectiveness of radon measurement and mitigation methods. In 1998, due to limited resources EPA privatised the radon programme. This paper presents a personal perspective of past events and current status of the US radon programme. It will present an update on radon health effects, the incidence rate of lung cancer in the USA and the number of radon measurements made from 1988 to 2013 using short-term test methods. More than 23 million measurements were made in the last 25 y and as a result more than 1.24 million homes were mitigated successfully. It is estimated that <2 % of the radon measurements performed in the USA are made using long-term testing devices. The number of homes above the US action level of 148 Bq m-3 (4 pCi l-1) may be ∼8.5 million because ∼50

    This publication presents a database of geologic analogs useful for the assessment of undiscovered oil and gas resources. Particularly in frontier areas, where few oil and gas fields have been discovered, assessment methods such as discovery process models may not be usable. In such cases, comparison of the assessment area to geologically similar but more maturely explored areas may be more appropriate. This analog database consists of 246 assessment units, based on the U.S. Geological Survey 2000 World Petroleum Assessment. Besides geologic data to facilitate comparisons, the database includes data pertaining to numbers and sizes of oil and gas fields and the properties of their produced fluids.

  15. Performance assessment of multi-state systems with critical failure modes: Application to the flotation metallic arsenic circuit

    International Nuclear Information System (INIS)

    This paper considers a number of alternative measures of multi-state systems with two failure modes. Almost all of them are based on a probabilistic model and the extent to which the multi-state system performance analysis may typically lead. The conventional multi-state theory is used to assess the fundamental problems of the performance of complex systems. In real life, it may be difficult to obtain sufficient data to estimate the precise values of the performance levels of modern engineering systems. This paper suggests reliability measures for multi-state systems with two failure modes, and presents a procedure for evaluating these measures. Generalized assumptions of multiple factors that may affect the reliability of such systems are introduced by developing multi-state operators that obey the commutative and the associative laws. The concepts of relevancy, coherency, and equivalence are used to characterize the properties of such systems. Mathematical problems raised by applications of multi-state system model in system failure engineering are addressed. Engineering case study of the flotation circuit of mineral processing plant is modeled as a homogeneous coherent multi-state system composed of homogeneous coherent multi-state subsystems, and its reliability is calculated.

  16. Transit time distributions to assess present and future contamination risk of karst aquifers over Europe and the Mediterranean

    Karst develops through the dissolution of carbonate rock. Karst groundwater in Europe is a major source of fresh water contributing up to half of the total drinking water supply in some countries. Climate model projections suggest that in the next 100 years, karst regions will experience a strong increase in temperature and a serious decrease of precipitation - especially in the Mediterranean region. Previous work showed that the karstic preferential recharge processes result in enhanced recharge rates and future climate sensitivity. But as there is fast water flow form the surface to the aquifer, there is also an enhanced risk of groundwater contamination. In this study we will assess the contamination risk of karst aquifers over Europe and the Mediterranean using simulated transit time distributions. Using a new type of semi-distributed model that considers the spatial heterogeneity of the karst system by distribution functions we simulated a range of spatially variable pathways of karstic groundwater recharge. The model is driven by the bias-corrected 5 GCMs of the ISI-MIP project (RCP8.5). Transit time distributions are calculated by virtual tracer experiments. These are repeated several times in the present (1991-2010) and the future (2080-2099). We can show that regions with larger fractions of preferential recharge show higher risks of contamination and that spatial patterns of contamination risk change towards the future.

    2011-01-01

    Flow cytometry is now a recognized methodology within animal spermatology, and has moved from being a research tool to become routine in the assessment of animal semen destined to breeding. The availability of 'bench-top' flow cytometers and of newer and versatile markers for cell structure and function had allowed the instrumentation to measure more sperm parameters, from viability to reactiveness when exposed to exogenous stimuli, and to increase our capabilities to sort spermatozoa for potential fertilizing capacity, or chromosomal sex. The present review summarizes the state of the art regarding flow cytometry applied to animal andrology, albeit keeping an open comparative intent. It critically evaluates the present and future capabilities of flow cytometry for the diagnostics of potential fertility and for the development of current reproductive technologies such as sperm freezing, sperm selection and sperm sorting. The flow cytometry methods will probably further revolutionize our understanding of the sperm physiology and their functionality, and will undoubtedly extend its application in isolating many uncharacterized features of spermatozoa. However, continuous follow-up of the methods is a necessity owing to technical developments and the complexity of mapping spermatozoa.

    Full Text Available Global wetlands are believed to be climate sensitive, and are the largest natural emitters of methane (CH4. Increased wetland CH4 emissions could act as a positive feedback to future warming. The Wetland and Wetland CH4 Inter-comparison of Models Project (WETCHIMP investigated our present ability to simulate large-scale wetland characteristics and corresponding CH4 emissions. To ensure inter-comparability, we used a common experimental protocol driving all models with the same climate and carbon dioxide (CO2 forcing datasets. The WETCHIMP experiments were conducted for model equilibrium states as well as transient simulations covering the last century. Sensitivity experiments investigated model response to changes in selected forcing inputs (precipitation, temperature, and atmospheric CO2 concentration. Ten models participated, covering the spectrum from simple to relatively complex, including models tailored either for regional or global simulations. The models also varied in methods to calculate wetland size and location, with some models simulating wetland area prognostically, while other models relied on remotely sensed inundation datasets, or an approach intermediate between the two.

    Four major conclusions emerged from the project. First, the suite of models demonstrate extensive disagreement in their simulations of wetland areal extent and CH4 emissions, in both space and time. Simple metrics of wetland area, such as the latitudinal gradient, show large variability, principally between models that use inundation dataset information and those that independently determine wetland area. Agreement between the models improves for zonally summed CH4 emissions, but large variation between the models remains. For annual global CH4 emissions, the models vary by ±40% of the all-model mean (190 Tg CH4 yr−1. Second, all

    The traditional lecturing method is still one of the most common forms of delivering content to students in dental education, but innovative learning technologies have the potential to improve the effectiveness and quality of teaching dental students. What challenges instructors is the extent to which these learning tools have a direct impact on student learning outcomes. The aim of this study was to assess the impact of a voice-over screen-captured learning tool by identifying a positive, nil, or negative impact on student learning as well as student engagement (affective, behavioral, and cognitive) when compared to the traditional face-to-face lecture. Extraneous variables thought to impact student learning were controlled by the use of baseline measures as well as random assignment of second-year dental students to one of two teaching conditions: voice-over screen-captured presentation delivered online and the traditional classroom lecture. A total of 28 students enrolled in the preclinical course in endodontics at a Canadian dental school participated in the study, 14 in each of the two teaching conditions. The results showed that, in most cases, the students who experienced the online lecture had somewhat higher posttest scores and perceived satisfaction levels than those in the face-to-face lecture group, but the differences did not achieve statistical significance except for their long-term recognition test scores. This study found that the students had comparable learning outcomes whether they experienced the face-to-face or the online lecture, but that the online lecture had a more positive impact on their long-term learning. The controls for extraneous variables used in this study suggest ways to improve research into the comparative impact of traditional and innovative teaching methods on student learning outcomes.

    Full Text Available Many agricultural species have undergone selection for traits that are consistent with those that increase the probability that a species will become invasive. However, the risk of invasion may be accurately predicted for the majority of plant species tested using the Australian Weed Risk Assessment (WRA. This system has been tested in multiple climates and geographies and, on average, correctly identifies 90% of the major plant invaders as having high invasion risk, and 70% of the noninvaders as having low risk. We used this tool to evaluate the invasion risk of 38 Eucalyptus taxa currently being tested and cultivated in the USA for pulp, biofuel, and other purposes. We predict 15 taxa to have low risk of invasion, 14 taxa to have high risk, and 9 taxa to require further information. In addition to a history of naturalization and invasiveness elsewhere, the traits that significantly contribute to a high invasion risk conclusion include having prolific seed production and a short generation time. Selection against these traits should reduce the probability that eucalypts cultivated in the USA will become invasive threats to natural areas and agricultural systems.

    Phosphorus (P) is an important macronutrient that can limit aquatic primary production and the risk of harmful algal blooms. Although there is considerable evidence that P release from sediments can represent a significant source of P and burial in sediments returns P to the geological sink; these processes have been poorly characterised. In this study, we applied a non-steady state reactive transport diagenetic model to gain insights into the dynamics of phosphorus binding forms in sediments and the phosphorus cycling of the Bay of Quinte, an embayment of Lake Ontario, Canada. The three basins of the bay (Belleville, Hay Bay and Napanee) that we investigated had differences in their phosphorus binding forms and phosphorus release, reflecting the distinct spatial temporal patterns of land use and urbanization levels in the watershed. Sediment cores from the three stations were collected during summer and under ice cover in 2013-14. Oxygen, pH and redox potential were monitored by microsensors; porewater and sediment solid matter were analyzed for P content, and a sequential extraction was used to analyze P binding forms. In the reaction-transport model, total phosphorus was divided into adsorbed phosphorus, phosphorus bound with aluminium, organic phosphorus, redox sensitive and apatite phosphorus. Using the fluxes of organic and inorganic matter as dynamic boundary conditions, we simulated the depth profiles of solute and solid components. The model closely reproduced the fractionation data of phosphorus binding forms and soluble reactive phosphorus. The past and present P fluxes were calculated and estimated; they related to geochemical conditions, and P binding forms in sediments. Our results show that P release from sediments is dominated by the redox-sentive P fraction accounting for higher percentage at Napanee station. The main P binding form that can be immobilized through diagenesis is apatite P contributing highest P retention at HayBay station. The mass

    Threats of nuclear terrorism are increasing after 9/11 terrorist attack. Treats include nuclear explosive device (NED) made by terrorist groups, radiological damage caused by a sabotage aiming nuclear facilities, and radiological dispersion device (RDD), which is also called 'dirty bomb'. In 9/11, Al Qaeda planed to cause radiological consequences by the crash of a nuclear power plant and the captured airplane. The evidence of a dirty bomb experiment was found in Afganistan by the UK intelligence agency. Thus, the international communities including the IAEA work substantial efforts. The leaders of 47 nations attended the 2010 nuclear security summit hosted by President Obama, while the next global nuclear summit will be held in Seoul, 2012. Most states established and are maintaining state's nuclear security regime because of the increasing threat and the international obligations. However, each state's nuclear security regime is different and depends on the state's environment. The methodology for the assessment of state's nuclear security regime is necessary to design and implement an efficient nuclear security regime, and to figure out weak points. The IAEA's INPRO project suggests a checklist method for State's nuclear security regime. The IAEA is now researching more quantitative methods cooperatively with several countries including Korea. In this abstract, methodologies to evaluate state's nuclear security regime by risk assessment are addressed

  5. A state-of-practice survey of policy, plan, and program assessment in Canadian provinces

    International Nuclear Information System (INIS)

    Since the introduction of the 1999 Canadian Cabinet Directive on the environmental assessment of policies, plans, and programs (PPPs), higher-order environmental assessment has been receiving increased attention in Canada. However, while practices and systems are advancing at the federal level, there has been very little attention given to recent developments in PPP assessment at the provincial level. This paper presents the results of a Canada-wide survey of PPP assessment principles and practices in 10 Canadian provincial EA jurisdictions. The findings indicate that there exists considerable variability in the provisions for and practice of PPP assessment amongst Canadian provinces, with only Saskatchewan, Ontario, and Quebec identifying recent practice experience. Included amongst the main barriers to effective implementation at the provincial level are the lack of legislative requirements for strategic EA, and the limited understanding of the nature and benefits of higher-order impact assessment

    Efficiently reducing natural hazard risks requires a thorough understanding of the costs of natural hazards. Current methods to assess these costs employ a variety of terminologies and approaches for different types of natural hazards and different impacted sectors. This may impede efforts to ascertain comprehensive and comparable cost figures. In order to strengthen the role of cost assessments in the development of integrated natural hazard management, a review of existing cost assessment approaches was undertaken. This review considers droughts, floods, coastal and Alpine hazards, and examines different cost types, namely direct tangible damages, losses due to business interruption, indirect damages, intangible effects, and the costs of risk mitigation. This paper provides an overview of the state-of-the-art cost assessment approaches and discusses key knowledge gaps. It shows that the application of cost assessments in practice is often incomplete and biased, as direct costs receive a relatively large amount of attention, while intangible and indirect effects are rarely considered. Furthermore, all parts of cost assessment entail considerable uncertainties due to insufficient or highly aggregated data sources, along with a lack of knowledge about the processes leading to damage and thus the appropriate models required. Recommendations are provided on how to reduce or handle these uncertainties by improving data sources and cost assessment methods. Further recommendations address how risk dynamics due to climate and socio-economic change can be better considered, how costs are distributed and risks transferred, and in what ways cost assessment can function as part of decision support.

  13. Assessment of buckling-restrained braced frame reliability using an experimental limit-state model and stochastic dynamic analysis

    Institute of Scientific and Technical Information of China (English)

    Blake M. Andrews; Junho Song; Larry A. Fahnestock

    2009-01-01

    Buckling-restrained braces (BRBs) have recently become popular in the United :States for use as primary members of seismic lateral-force-resisting systems. A BRB is a steel brace that does not buckle in compression but instead yields in both tension and compression. Although design guidelines for BRB applications have been developed, systematic procedures for assessing performance and quantifying reliability are still needed. This paper presents an analytical framework for assessing buckling-restrained braced frame (BRBF) reliability when subjected to seismic loads. This framework efficiently quantifies the risk of BRB failure due to low-cycle fatigue fracture of the BRB core. The procedure includes a series of components that: (1) quantify BRB demand in terms of BRB core deformation histories generated through stochastic dynamic analyses; (2) quantify the limit-state of a BRB in terms of its remaining cumulative plastic ductility capacity based on an experimental database; and (3) evaluate the probability of BRB failure, given the quantified demand and capacity, through structural reliability analyses. Parametric studies were conducted to investigate the effects of the seismic load, and characteristics of the BRB and BRBF on the probability of brace failure. In addition, fragility curves (i.e., conditional probabilities of brace failure given ground shaking intensity parameters) were created by the proposed framework. While the framework presented in this paper is applied to the assessment of BRBFs, the modular nature of the framework components allows for application to other structural components and systems.

The other aspects which are also very important, relate to its ease of using, user understanding and faith in the results, and method reliability (Hobbs et al., 1992.This section presents a new systematic MCDM approach, RALSPI, for evaluating and ranking alternatives. In fact, the RALSPI is a systematic method for decision problems with many criteria and alternatives. The algorithm for the proposed approach will be developed in eight steps. In this method, decisional process is decomposed into a hierarchy of criteria clusters, criteria, and alternatives. The RALSPI procedure is as follows: (In the RALSPI method, the decision matrix and the weight vector w are given as crisp values a priori.Step 1: classifying all criteria into some major categories First, it is necessary to categorize criteria according to thematic homogeneity. It is preferred that the number of criteria lie in various groups be balanced. This rule facilitates the management of studied criteria. (N: number of all studied criteria; k: number of criteria categories; n: number of criteria related to each categoryStep 2: Normalization of the criteria The RALSPI method first converts the various criteria dimensions into non-dimensional criteria. For a sets of benefit attributes, each normalized criterion Iij is calculated as follows: The value of the Iij is computed on a scale of 0–1 where 0 corresponds to the minimum, and 1 to the maximum assigned value for the corresponding indicator.Step 3: Classifying the amount of Iij into three levelsIn this step, three levels for each criterion are defined so that different values are

  15. Assessment of domino effect: State of the art and research Needs

    International Nuclear Information System (INIS)

    High-impact low-probability (HILP) accident scenarios in industrial sites are raising a growing concern. Domino effect was responsible of several catastrophic accidents that affected the chemical and process industry, as well as critical infrastructures for energy as oil refineries. However, there is still a poor agreement on assessment procedures to address escalation hazard resulting in domino scenarios. The present study presents a review of the work done in the last 30 years in the field, and a critical analysis of available tools and knowledge gaps concerning domino effect assessment. The analysis of scientific publications concerning domino effect in the process industry resulted in a database of more than 60 documents, addressing three main issues: past accident analysis, models for equipment damage, risk assessment and safety management of domino scenarios. The methods, models and tools developed make now possible the quantitative assessment of domino scenarios in risk analysis and in safety management of industrial sites. Nevertheless, a number of open points still remain, where existing tools may be improved and uncertainty may be reduced. - Highlights: • Research work and related publications concerning domino effect in the last 30 years were revised. • Three main research topics in domino effect were identified. • Currently available tools allow the quantitative assessment and management of domino scenarios. • Escalation assessment may benefit from more detailed equipment damage models. • Dynamic tools for consequence assessment may improve impact assessment of domino scenarios

    on GL GH’s review of U.S. ports infrastructure and its readiness to support the development of proposed offshore wind projects in U.S. waters. Specific examples of facility costs and benefits are provided for five coastal regions (North Atlantic, South Atlantic, Gulf of Mexico, Great Lakes, and Pacific) around the country. GL GH began this study by identifying the logistical requirements of offshore wind ports to service offshore wind. This review was based on lessons learned through industry practice in Northern Europe. A web-based port readiness assessment tool was developed to allow a capability gap analysis to be conducted on existing port facilities based on the identified requirements. Cost models were added to the assessment tool, which allowed GL GH to estimate the total upgrade cost to a port over the period 2014-2030 based on a set of regional project build-out scenarios. Port fee information was gathered from each port allowing an estimate of the potential revenue to the port under this same set of scenarios. The comparison of these revenue and improvement cost figures provides an initial indication of the level of offshore wind port readiness. To facilitate a more in-depth infrastructure analysis, six ports from different geographic regions, with varied levels of interest and preparedness towards offshore wind, were evaluated by modeling a range of installation strategies and port use types to identify gaps in capability and potential opportunities for economic development. Commonalities, trends, and specific examples from these case studies are presented and provide a summary of the current state of offshore wind port readiness in the U.S. and also illustrate the direction some ports have chosen to take to prepare for offshore wind projects. For example, the land area required for wind turbine and foundation manufacturing is substantial, particularly due to the large size of offshore wind components. Also, the necessary bearing capacities of the

    Full Text Available In this article the state of implementation of anti-corruption policy in Ukraine has been analyzed. The basic legal and regulatory backgrounds of the country’s anti-corruption activities are examined. Based on analysis of the ways of improving the state anticorruption policy, improve the efficiency of its practical implementation in Ukraine. Corruption remains a major problem in Ukraine and continues to threaten its economic development, political stability, reputation (confidence level of the public authorities. Analyzing the phenomenon of corruption, it is necessary to emphasize that corruption is reformed in a reliable instrument to implement or achieve certain goals not only in individual format, but like leverage in the form of inter-state relations. This article shows the Ukraine’s achievement in the field of development the legislating basis for anticorruption policy, the practical instruments of its implementation on the institutional level. Steps made by the new elected authority involving publicity in order to improve the transparency and integrity building are reviewed as well as main tasks of the country to combat the corruption and the recommendations for its capability development. Combating corruption, our country has made considerable progress through the adoption of the anti-corruption legislation. It also covers reform of relevant government institutions that are unconditional guarantee of performance and implementing the rules. Many changes occurred and continue to occur with the support and under the close supervision of the foreign community, as well as a number of international organizations and institutions. At the same time, while preparing this materiel the influence of the international lessons learned experience had been taking in to consideration, which found its reflection and was actively implemented in the creating of anticorruption programs of governmental establishments as well as in Ministry of Defence.

    Full Text Available Background. Sparse data limit the interpretation of Montreal Cognitive Assessment (MoCA scores, particularly in minority populations. Additionally, there are no published data on how MoCA scores compare to the widely used Modified Mini Mental State Examination (3MSE. We provide performance data on the MoCA in a large cohort of African Americans and compare 3MSE and MoCA scores, providing a “crosswalk” for interpreting scores. Methods. Five hundred and thirty African Americans with type 2 diabetes were enrolled in African American-Diabetes Heart Study-MIND, a cross-sectional study of cognition and structural and functional brain imaging. After excluding participants with possible cognitive impairment (n=115, mean (SD MoCA and 3MSE scores are presented stratified by age and education. Results. Participant mean age was 58.2 years (range: 35-83; 61% were female; and 64.9% had >12 years of education. Mean (SD 3MSE and MoCA scores were 86.9 (8.2 and 19.8 (3.8, respectively. 93.5% of the cohort had a “positive” screen on the MoCA, scoring <26 (education-adjusted, compared with 47.5% on the 3MSE (cut-point < 88. A 3MSE score of 88 corresponded to a MoCA score of 20 in this population. Conclusion. The present data suggest the need for caution when applying proposed MoCA cutoffs to African Americans.

    1981-12-01

    Reported herein is a summary of work conducted under the Resource Assessment Program-Task 2, for the Utah State Prison Geothermal Space Heating Project at Crystal Hot Springs, Draper, Utah. Assessment of the geothermal resource in and around the Utah State Prison property began in october of 1979 with an aeromagnetic and gravity survey. These tasks were designed to provide detailed subsurface structural information in the vicinity of the thermal springs so that an informed decision as to the locations of test and production holes could be made. The geophysical reconnaissance program provided the structural details needed to focus the test drilling program on the most promising production targets available to the State Prison. The subsequent drilling and well testing program was conducted to provide information to aid fin the siting and design of a production well and preliminary design activities. As part of the resource assessment portion of the Utah State Prison Geothermal Project, a program for periodic geophysical monitoring of the Crystal Hot Springs resource was developed. The program was designed to enable determination of baseline thermal, hydraulic, and chemical characteristics in the vicinity of Crystal Hot Springs prior to production and to provide a history of these characteristics during resource development.

  1. Global assessments of the state of the marine environment: Contemporary initiatives

    International Nuclear Information System (INIS)

    A large number of assessments of regional marine areas have been conducted in recent years for a variety of purposes. Periodic reviews of the state of the marine environment have been undertaken by the United Nations Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP). The most recent of these global assessments was published in 1990. The international adoption of a Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities in 1995 has led to additional demand for regional assessments and a global review. The regional assessments are either completed or in train largely through mechanisms associated with the UNEP Regional Seas Programme. The global assessment has been assigned to GESAMP and incorporated into its plans for the preparation of a new global review to be completed in the year 2002. The Intergovernmental Oceanographic Commission, (IOC) the Scientific Committee for Oceanic Research (SCOR) and the Scientific Committee on Problems of the Environment (SCOPE) are collaborating in a review of ocean science. The Global Environment Facility (GEF) recently approved funding for a 'Global International Waters Assessment' (GIWA) partly as a means of determining priorities within its International Waters Portfolio. This paper outlines the nature of, and contemporary activities within, these various assessments. (author)

  3. Present status of solid state photoelectrochemical solar cells and dye sensitized solar cells using PEO-based polymer electrolytes

    International Nuclear Information System (INIS)

    Due to energy crises in the future, much effort is being directed towards alternate sources. Solar energy is accepted as a novel substitute for conventional sources of energy. Out of the long list of various types of solar cells available on the market, solid state photoelectrochemical solar cells (SSPECs) and dye sensitized solar cells (DSSCs) are proposed as an alternative to costly crystalline solar cell. This review provides a common platform for SSPECs and DSSCs using polymer electrolyte, particularly on polyethylene oxide (PEO)-based polymer electrolytes. Due to numerous advantageous properties of PEO, it is frequently used as an electrolyte in both SSPECs as well as DSSCs. In DSSCs, so far high efficiency (more than 11%) has been obtained only by using volatile liquid electrolyte, which suffers many disadvantages, such as corrosion, leakage and evaporation. The PEO-based solid polymer proves its importance and could be used to solve the problems stated above. The recent developments in SSPECs and DSSCs using modified PEO electrolytes by adding nano size inorganic fillers, blending with low molecular weight polymers and ionic liquid (IL) are discussed in detail. The role of ionic liquid in modifying the electrical, structural and photoelectrochemical properties of PEO polymer electrolytes is also described. (review)

Fayzul K. [California State University, Fresno; Oubeidillah, Abdoul A [ORNL; Smith, Brennan T [ORNL

    2014-04-01

    The rapid development of multiple national geospatial datasets related to topography, hydrology, and environmental characteristics in the past decade have provided new opportunities for the refinement of hydropower resource potential from undeveloped stream-reaches. Through 2011 to 2013, the Oak Ridge National Laboratory (ORNL) was tasked by the Department of Energy (DOE) Water Power Program to evaluate the new stream-reach development (NSD) resource potential for more than 3 million US streams. A methodology was designed that contains three main components: (1) identification of stream-reaches with high energy density, (2) topographical analysis of stream-reaches to estimate inundated surface area and reservoir storage, and (3) environmental attribution to spatially join information related to the natural ecological systems, social and cultural settings, policies, management, and legal constraints to stream-reaches of energy potential. An initial report on methodology (Hadjerioua et al., 2013) was later reviewed and revised based on the comments gathered from two peer review workshops. After implementing the assessment across the entire United States, major findings were summarized in this final report. The estimated NSD capacity and generation, including both higher-energy-density (>1 MW per reach) and lower-energy-density (<1 MW per reach) stream-reaches is 84.7 GW, around the same size as the existing US conventional hydropower nameplate capacity (79.5 GW; NHAAP, 2013). In terms of energy, the total undeveloped NSD generation is estimated to be 460 TWh/year, around 169% of average 2002 2011 net annual generation from existing conventional hydropower plants (272 TWh/year; EIA, 2013). Given the run-of-river assumption, NSD stream-reaches have higher capacity factors (53 71%), especially compared with conventional larger-storage peaking-operation projects that usually have capacity factors of around 30%. The highest potential is identified in the Pacific Northwest

  6. Assessment of brain activities during an emotional stress state using fMRI

    International Nuclear Information System (INIS)

    We investigated cerebrum activation using functional magnetic resonance imaging during a mental stress state. Thirty-four healthy adults participated. Before the experiment, we assessed their stress states using the Stress Self-rating Scale and divided the participants into Stress and Non-stress groups. The experiment consisted of 6 trials. Each trial consisted of a 20-s block of emotional audio-visual stimuli (4-s stimulation x 5 slides) and a fixation point. These processes were performed 3 times continuously (Relaxed, Pleasant, Unpleasant stimuli) in a random order. These results showed that the Non-stress group indicated activation of the amygdala and hippocampus in the Pleasant and Unpleasant stimuli while the Stress group indicated activation of the hippocampus in Pleasant stimuli, and the amygdala and hippocampus in Unpleasant stimuli. These findings suggested that the mental stress state engages the reduction of emotional processing. Also, the responsiveness of the memory system remained during and after the emotional stress state. (author)

    Full Text Available This study examined the influence of continuous assessment in the teaching of mathematics in secondary schools in Edo State. Four research questions and hypotheses guided the study. The research employed a survey design. Seventy (70 mathematics teachers were randomly selected from a population of over (240 mathematics teachers in secondary schools in Edo State, Nigeria. A well structured likert type of questionnaire containing (20 items was employed while chi square goodness of fit was the major statistical tool used for data analysis. A co-efficient of 0.75 was obtained for the instrument using Cronbach high co-efficient reliability test. The results showed that the practice of continuous assessment has a significant relationship with students’ academic performance in mathematics and also help to motivate students’ in the teaching and learning of mathematics. Based on these results, conclusions and recommendations were made. Some of these are: The government should frequently organize workshops, seminars and conferences for serving mathematics teachers on the practice of continuous assessment in secondary schools. Institutions of higher learning should make continuous assessment a major course in their pre-service teachers training programme. The undergraduate education mathematics course should be widened to cover all aspects of continuous assessment.

    2016-01-01

    Full Text Available Many researchers have highlighted the central role that assessment plays in second language (L2 classrooms and have expressed the need for research into classroom-based language assessment (CBLA, an area that is gradually coming into its own in the field of language testing and assessment (e.g., Hasselgreen, 2008; Leung, 2014; Hill & McNamara, 2012; Turner, 2012. Motivated by the prominence of CBLA in recent discussions, the present study set out to investigate the CBLA practices, knowledge and skills of Greek and Cypriot primary school EFL teachers. The data was collected through teacher interviews and classroom-based tests. The results showed that teachers employ a summative orientation towards evaluating their students’ performance and seem to have unclear ideas about the purposes and implementation of formative assessment, mainly due to lack of professional training in language assessment. The paper concludes with suggestions as to how EFL teachers’ CBLA literacy can be enhanced.

    2007-01-01

    Using the theory and method of unascertained measure, an unascertained measure model and the related confidence rule are established to assess the safety state of ship. Thus, the dangerous factors in the hull system can be identified, and the accident possibility, loss, and injury degree can be forcasted. An application result shows that the the proposed method is effective in assessment of the traffic safety of ships, and it is more simple in computation than the fuzzy synthetic evaluation method. The proposed method can provide a scientific basis for realizing shipping transportation security and formulating preventive measures.

  10. Risk management and the vulnerability assessment process of the United States Department of Energy

    International Nuclear Information System (INIS)

    Full text: Risk management is an essential element in influencing how the United States Department of Energy's safeguards and security mission is executed. Risk management exists as a function of a target's attractiveness, along with the potential consequences associated with the unauthorized use of that target. The goal of risk management encompasses the fielding and operating of appropriate, cost-effective protection systems generating sufficient deterrence to protect sensitive programs and facilities. Risk mitigation and risk prevention are accomplished through the vulnerability assessment process. The implementation and continued validation of measures to prevent or mitigate risk to acceptable levels constitute the fundamental approach of the Department's risk management program. Due to the incomplete knowledge inherent in any threat definition, it is impossible to precisely tailor a protective system to defend against all threats. The challenge presented to safeguards and security program managers lies in developing systems sufficiently effective to defend against an array of threats slightly greater than can be hypothetically postulated (the design basis threat amended for local conditions). These systems are then balanced against technological, resource, and fiscal constraints. A key element in the risk assessment process is analyzing the security systems against the Design Basis Threat (DBT). The DBT is used to define the level and capability of the threat against the DOE facilities and their assets. In particular it defines motivation, numbers of adversaries, capabilities, and their objectives. Site Safeguards and Security Plans (SSSPs) provide the basis and justification for safeguards and security program development, budget, and staffing requirements. The SSSP process examines, describes, and documents safeguards and security programs, site-wide and by facility; establishes safeguards and security program improvement priorities; describes site and

    2D surface maps of light distribution and temperature increase were recorded in wild type anesthetized rats brains during 90s light stimulation at 478nm (blue) and 638nm (red) with continuous or pulsed optical stimulations with corresponding power ranging from 100 up to 1200 mW/mm² at the output of an optical fiber. Post mortem maps were recorded in the same animals to assess the cooling effect of blood flow. Post mortem histological analysis were carried out to assess whether high power light stimulations had phototoxic effects or could trigger non physiological functional activation. Temperature increase remains below physiological changes (0,5 -1°) for stimulations up to 400mW/mm² at 40Hz. . Histology did not show significant irreversible modifications or damage to the tissues. The spatial profile of light distribution and heat were correlated and demonstrate as expected a rapid attenuation with diatnce to the fiber.

    Otolaryngologists utilize a variety of diagnostic techniques to assess middle ear health. Tympanometry, audiometry, and otoacoustic emissions examine the mobility of the tympanic membrane (eardrum) and ossicles using ear canal pressure and auditory tone delivery and detection. Laser Doppler vibrometry provides non-contact vibrational measurement, and acoustic reflectometry is used to assess middle ear effusion using sonar. These technologies and techniques have advanced the field beyond the use of the standard otoscope, a simple tissue magnifier, yet the need for direct visualization of middle ear disease for superior detection, assessment, and management remains. In this study, we evaluated the use of portable optical coherence tomography (OCT) and pneumatic low-coherence interferometry (LCI) systems with handheld probe delivery to standard tympanometry, audiometry, otoacoustic emissions, laser Doppler vibrometry, and acoustic reflectometry. Comparison of these advanced optical imaging techniques and current diagnostics was conducted with a case study subject with a history of unilateral eardrum trauma. OCT and pneumatic LCI provide novel dynamic spatiotemporal structural data of the middle ear, such as the thickness of the eardrum and quantitative detection of underlying disease pathology, which could allow for more accurate diagnosis and more appropriate management than currently possible.

    2010-12-01

    Full Text Available Ever since the emigration from the Nordic countries the Old world and the New world have maintained an exchange of ideas, customs, and material culture. This cultural heritage consists of more than remnants of the past. Drawing on theories of material culture and performance this article highlights the role of gifts in mate-rializing relationships between individuals, families and organizations in the wake of migration. First, I build on a suggested coinage of the term heritage gifts as a way of materializing relationships. Thereafter, I map out the numerous roles which a Swedish bridal crown play in the United States: as museum object, object of display and loaned to families for wedding ceremonies in America. The trans-fers and transformations of the bridal crown enhances a drama of a migration her-itage. This dynamic drama brings together kin in Sweden and America and maps specific locations into a flexible space via the trajectory of crown-clad female bodies.

  14. State of the art on the probabilistic safety assessment (P.S.A.)

    International Nuclear Information System (INIS)

    The use of Probabilistic Safety Assessment (PSA) is internationally increasing as a means of assessing and improving the safety of nuclear and non-nuclear facilities. To support the development of a competence on Probabilistic Safety Assessment, a set of states of the art regarding these tools and their use has been made between 2001 and 2005, in particular on the following topics: - Definition of the PSA of level 1, 2 and 3; - Use of PSA in support to design and operation of nuclear plants (risk-informed applications); - Applications to Non Reactor Nuclear Facilities. The report compiled in a single document these states of the art in order to ensure a broader use; this work has been done in the frame of the Project 'Reliability and Safety of Nuclear Facility' of the Nuclear Development and Innovation Division of the Nuclear Energy Division. As some of these states of the art have been made in support to exchanges with international partners and were written in English, a section of this document is written in English. This work is now applied concretely in support to the design of 4. Generation nuclear systems as Sodium-cooled Fast Reactors and especially Gas-cooled Fast Reactor, that have been the subject of communications during the conferences ANS (Annual Meeting 2007), PSA'08, ICCAP'08 and in the journal Science and Technology of Nuclear Installations.

    Thanks to advances in medical care, an increased number of patients recover from coma. However, some remain in vegetative/unresponsive wakefulness syndrome or in a minimally conscious state. Detection of awareness in severely brain-injured patients is challenging because it relies on behavioral assessments, which can be affected by motor, sensory and cognitive impairments of the patients. Other means of evaluation are needed to improve the accuracy of the diagnosis in this challenging population. We will here review the different altered states of consciousness occurring after severe brain damage, and explain the difficulties associated with behavioral assessment of consciousness. We will then describe a non-invasive technique, transcranial magnetic stimulation combined with high-density electroencephalography (TMS-EEG), which has allowed us to detect the presence or absence of consciousness in different physiological, pathological and pharmacological states. Some potential underlying mechanisms of the loss of consciousness will then be discussed. In conclusion, TMS-EEG is highly promising in identifying markers of consciousness at the individual level and might be of great value for clinicians in the assessment of consciousness.

    2007-12-01

    Full Text Available Old growth in the frequent-fire conifer forests of the western United States, such as those containing ponderosa pine (Pinus ponderosa, Jeffrey pine (P. jeffreyi, giant sequoia (Sequioa giganteum and other species, has undergone major changes since Euro-American settlement. Understanding past changes and anticipating future changes under different potential management scenarios are fundamental to developing ecologically based fuel reduction or ecological restoration treatments. Some of the many changes that have occurred in these forests include shifts from historically frequent surface fire to no fire or to stand-replacing fire regimes, increases in tree density, increased abundance of fire-intolerant trees, decreases in understory productivity, hydrological alterations, and accelerated mortality of old trees. Although these changes are widespread, the magnitude and causes of changes may vary within and among landscapes. Agents of change, such as fire exclusion or livestock grazing, likely interacted and had multiple effects. For example, historical ranching operations may have altered both fire regimes and understory vegetation, and facilitated institutional fire exclusion through fragmentation and settlement. Evidence exists for large variation in presettlement characteristics and current condition of old growth across this broad forest region, although there are many examples of striking similarities on widely distant landscapes. Exotic species, climate change, unnatural stand-replacing wildfires, and other factors will likely continue to degrade or eradicate old growth in many areas. As a policy of fire exclusion is proving to be unsustainable, mechanical tree thinning, prescribed fire, or wildland fire use will likely be key options for forestalling continued eradication of old growth by severe crown fires. For many practical and societal reasons, the wildland–urban interface may afford some of the most immediate opportunities for re

  17. Present status of fast neutron personnel dosimetry system based on CR-39 solid state nuclear track detectors

    International Nuclear Information System (INIS)

    Neutron sources are of different types depending upon the method of production such as nuclear reactors, particle accelerators and laboratory sources. Neutron sources depending upon their energy, flux, size etc. are used for variety of applications in basic and applied sciences, neutron scattering experiments and in industry such as oil well - digging, coal mining and processing, ore processing etc. Personnel working in nuclear installations such as reactors, accelerators, spent fuel processing plants, nuclear fuel cycle operations and those working in various industries such as oil refining, oil well-digging, coal mining and processing, ore processing, etc. need to be monitored for neutron exposures, if any. Neutron monitoring is especially necessary in view of the fact that the radiation weighting factor for neutron is much higher than gamma rays and also it varies with energy. Radiological Physics and Advisory Division is involved in monitoring of personnel working in neutron fields. Around 2100 workers from 70 institutions (DAE and Non-DAE) are monitored on a quarterly basis. Neutron personnel monitoring, carried out in the country is based on Solid State Nuclear Track Detection (SSNTD) technique. In this technique, neutrons interact with hydrogen in CR-39 polymer to produce recoil protons. These protons create damages in the polymer, which are enlarged and appear as tracks when subjected to electrochemical etching (ECE). These tracks are counted in an optical system to evaluate the neutron dose. The neutron dosimetry system based on SSNTD has undergone a significant development, since it was started in 1990. The development includes upgradation of image analysis system for counting tracks, introduction of chemical etching (CE) at elevated temperatures for evaluation of dose equivalents above 10 mSv and use of carbon laser for cutting of CR-39 detectors. The entire dose evaluation process has been standardized, which includes calibration and performance tests

  18. Planning Science Instruction for Critical Thinking: Two Urban Elementary Teachers’ Responses to a State Science Assessment

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available Science education reform standards have shifted focus from exploration and experimentation to evidence-based explanation and argumentation to prepare students with knowledge for a changing workforce and critical thinking skills to evaluate issues requiring increasing scientific literacy. However, in urban schools serving poor, diverse populations, where the priority is on students’ assessment results in reading and math, students may not receive reform-based science. The rationale for this qualitative study was to examine how two elementary teachers from high-poverty urban schools planned for reform-based science in response to a quality state science assessment in conjunction with their training and resources. Their state assessment included an inquiry task requiring students to construct responses to questions based on their investigation data. From evaluating evidence using Zembal-Saul’s continuum for teaching science as argument, the findings indicated that both teachers adopted an investigation-based and evidence-based approach to science teaching to prepare students for the inquiry task. However, one teacher provided argument-based science teaching from her explicit training in that approach. The results suggested that the teachers’ training and resources informed their interpretation of the focus areas on the science assessment inquiry task and influenced the extent to which they offered students an equitable opportunity to develop higher-order thinking from reform-based science.

    Created by the US National Organ Transplant Act in 1984, the Scientific Registry of Transplant Recipients (SRTR) is obligated to publicly report data on transplant program and organ procurement organization performance in the United States. These reports include risk-adjusted assessments of graft and patient survival, and programs performing worse or better than expected are identified. The SRTR currently maintains 43 risk adjustment models for assessing posttransplant patient and graft survival and, in collaboration with the SRTR Technical Advisory Committee, has developed and implemented a new systematic process for model evaluation and revision. Patient cohorts for the risk adjustment models are identified, and single-organ and multiorgan transplants are defined, then each risk adjustment model is developed following a prespecified set of steps. Model performance is assessed, the model is refit to a more recent cohort before each evaluation cycle, and then it is applied to the evaluation cohort. The field of solid organ transplantation is unique in the breadth of the standardized data that are collected. These data allow for quality assessment across all transplant providers in the United States. A standardized process of risk model development using data from national registries may enhance the field. PMID:26814440

  20. Assessment of exposures to 131I in the continental United States resulting from the Nevada atmospheric nuclear tests

    International Nuclear Information System (INIS)

    The National Cancer Institute (NCI) is conducting an assessment of the exposure to 131I that the American people received from the fallout resulting from the atmospheric bomb tests carried out at the Nevada Test Site (NTS). It is estimated that about 5 EBq of 131I were released into the atmosphere as a result of approximately 100 tests carried out mainly in the 1950s. The most important source of human exposure from fallout 131I was due to the ingestion of cows' milk but other routes of exposure (ingestion of goats' milk, leafy vegetables, eggs, and cottage cheese as well as inhalation) are also considered. The exposure to 131I are assessed on a test-by-test and county-by-county basis. In order to make these estimates for locations throughout the United States, it is necessary to determine: The activities of 131I deposited on soil and vegetation, the amount of 131I consumed by dairy cows and the resulting 131I concentrations in cow's milk, and the 131I ingested by people. The overall methodology currently used in the assessment of the 131I exposures is presented. Particular attention is devoted to the methodology developed to estimate the intake of contaminated pasture by dairy cows, milk production, and milk distribution for each county of the continental United States during the 1950s

  1. From Site Data to Safety Assessment: Analysis of Present and Future Hydrological Conditions at a Coastal Site in Sweden

    International Nuclear Information System (INIS)

    This paper presents an analysis of present and future hydrological conditions at the Forsmark site in Sweden, which has been proposed as the site for a geological repository for spent nuclear fuel. Forsmark is a coastal site that changes in response to shoreline displacement. In the considered time frame (until year 10 000 ad), the hydrological system will be affected by landscape succession associated with shoreline displacement and changes in vegetation, regolith stratigraphy, and climate. Based on extensive site investigations and modeling of present hydrological conditions, the effects of different processes on future site hydrology are quantified. As expected, shoreline displacement has a strong effect on local hydrology (e.g., groundwater flow) in areas that change from sea to land. The comparison between present and future land areas emphasizes the importance of climate variables relative to other factors for main hydrological features such as water balances

    Full Text Available The Istanbul Strait has intense maritime traffic while, at the same time, it poses significant navigational challenges. Due to these properties, there is always a high risk arising from maritime shipping in this region. Especially, substandard ships threaten life, as well as the marine environment. In this aspect, Black Sea Memorandum of Understanding (MOU Port State Control Inspections are important for maritime safety in the Istanbul Strait, because they directly reflect the performance of ships passing through the Istanbul Strait. Stringent and effective inspections assist in the enhancement of navigation safety and help to develop sustainable environment management. In this context, this study aims to assess maritime safety for the Strait region concerning passing flag states. Firstly, to assess the performance of flag states in general, the Black Sea MOU Black-Grey-White lists were generated for the period 2004–2014 and the change in the performance of these flags was examined. Secondly, the risk level of each flag state passing from the Strait region was determined using the method of weighted points based on the Black-Grey-White List, deficiency index level, casualty index level, and passing index level.

    2016-05-30

    The efficacy and safety of a novel isoxazoline parasiticide, sarolaner (Simparica™), for the control of fleas on dogs was evaluated in a randomized, controlled clinical study conducted in 19 general veterinary practices throughout the United States. Four hundred and seventy nine (479) dogs from 293 households were enrolled. Each household was randomly assigned to treatment with either sarolaner oral tablets (Simparica™, Zoetis) at the proposed label dose or an approved comparator product at the label dose (spinosad, Comfortis(®), Elanco). Dogs were dosed by their owners at home on Day 0 and on approximately Days 30 and 60. Dogs were examined at the clinics for general health, flea and tick infestation, and clinical signs of flea allergy dermatitis (FAD) at the initial visit and Days 14, 30, 60 and 90. Blood was collected for clinical pathology at screening and Day 90. Sarolaner was well-accepted by dogs with the majority of flavored chewable tablets (91.5%) accepted free choice, by hand or in food. Geometric mean live flea counts were reduced by >99% at the first time measured (14 days) after initiation of treatment and continued to reduce through the study. Treatment success (proportion of dogs with ≥90% reduction in fleas) for the sarolaner-treated dogs was superior to that for spinosad-treated dogs at Days 14 and 30 and non-inferior on Days 60 and 90 (P≤0.025) The rapid reduction in flea infestations resulted in a similar rapid resolution of the clinical signs associated with FAD. Sarolaner chewable tablets were well tolerated with no treatment related adverse reactions. Most of the clinical signs reported were consistent with allergies and dermatitis or sporadic occurrences of conditions commonly observed in the general dog population. A wide variety of concomitant medications, including many commercially available heartworm preventatives and other anthelmintic drugs, were administered to study dogs and all were well tolerated. Sarolaner administered

    During the past 50 years the number of badgers (Meles meles) in Denmark has declined by c. 50%. To assess the genetic consequences of the demographic decline, six DNA-microsatellite loci were used to analyse 139 badger tissue-samples, which were collected in 1995-98 from three zones (1, 2 and 3) in...... Jutland (Denmark). Results from contemporary samples were compared to data obtained from DNA extracted from teeth belonging to 39 badgers collected from zones 1 and 2 in 1957-66. The microsatellites showed a low to moderate polymorphism, and the within area genetic diversity (H-E) was relatively low (0.......308 0.05). Despite the drastic recent decline, Danish badgers did not show apparent signs of genetic bottlenecks in both recent and historical samples. The use of molecular techniques which allowed us to work with small amounts of degraded DNA extracted from old teeth, allowed us to exclude the...

    Full Text Available The paper presents results of the research in wood fuels consumption for house-hold needs in Serbia. Research was performed during the period from October 2010 until April 2011, i. e. in the period of heating season in order to get the actual situation regarding the presence of certain fuel types in the consumption of households with special highlight on types and amounts of wood fuels. For this purpose, an adequate methodological concept was defined with the aim to primarily get relevant and reliable data on wood fuels consumption and afterwards, by using FAO WISDOM methodology and adequate GIS software packages to perform their analysis, mapping, and graphic representation. One of the most significant elements of the adopted methodological concept was field research-questionnaire of households which was conducted on the sample of 36.946 households out of which 20.725 urban and 16.221 rural in 22 municipalities in Serbia, which was 1.46% of the total number of households in Serbia. Results of the survey showed that 23.2% of the total number of households in Serbia used district heating system (based on conventional fossil fuels as dominant, 25.3% used electricity, and 10.6% used gas for heating purposes. Most households (40.9% used solid fuels such as fuelwood, coal, briquettes, pellets, agricultural residues and combinations of solid and other fuels.

  10. Present state of the perception gap of nuclear energy between Japanese nuclear energy supplying region and an energy consuming region

    International Nuclear Information System (INIS)

    Public opinion surveys have been carried out since 1998 on what phase and on what extent of the perception of nuclear energy differs between Japanese dwelling in energy supplying region and an energy-consuming region. Southern Fukui rural district where 15 nuclear reactors are now installed and Osaka urban region of about 100 km apart from Fukui were selected as the respective targets for the energy supplying and consuming regions. Analyses of the data of about 3000 samples have revealed the followings. (1) The public in the nuclear energy supplying region are very friendly to nuclear energy so that only about 20 and 39 of the public are resistive to the general promotion of nuclear energy in Japan and to the construction of another nuclear reactor in their dwelling region, respectively. (2) On the other hand, in the energy-consuming region those respective fractions are 41 and 70 implying strong resistance to nuclear energy in the urban region. (3) Both the degree of interest in and the degree of knowledge on nuclear energy are very low, whereas the extent of fear to nuclear is high for the urban public. (4) Not only the fraction of the public who are satisfied with their present life, but the public fraction who is eagerly support the thought of return-to-nature are very high in the urban region. (5) On the other hand, in the energy supplying region, many peoples eagerly want their life to become more convenient than it is now, and 6) all those trends (I)-(5) are revealed more pronouncedly in the woman than the man. The perception gap of nuclear energy thus became clear between Japanese dwelling in rural and urban regions. On the basis of this knowledge, discussions on the nature of the so-called NIMBY will be made from the socio-psychological viewpoint and propositions will also be made on the methods to dissolve the perception gap of that soft.

    1993-12-01

    The mandate of this research report was to provide the state of Hawaii with an assessment of the potential opportunities and drawbacks of relying on coal-fired generating technologies to diversify its fuel mix and satisfy future electric power requirements. This assessment was to include a review of existing and emerging coal-based power technologies-including their associated costs, environmental impacts, land use, and infrastructure requirements-to determine the range of impacts likely to occur if such systems were deployed in Hawaii. Coupled with this review, the report was also to (1) address siting and safety issues as they relate to technology choice and coal transport, (2) consider how environmental costs associated with coal usage are included in the integrated resource planning (ERP) process, and (3) develop an analytical tool from which the Department of Business, Economic Development & Tourism of the State of Hawaii could conduct first-order comparisons of power plant selection and siting. The prepared report addresses each element identified above. However, available resources and data limitations limited the extent to which particular characteristics of coal use could be assessed. For example, the technology profiles are current but not as complete regarding future developments and cost/emissions data as possible, and the assessment of coal technology deployment issues in Hawaii was conducted on an aggregate (not site-specific) basis. Nonetheless, the information and findings contained in this report do provide an accurate depiction of the opportunities for and issues associated with coal utilization in the state of Hawaii.

    2004-07-01

    A thorough description of the initial state of the engineered parts of the repository system is one of the main bases for the SR-Can safety assessment. The initial state refers to the state at the time of deposition for the spent fuel and the engineered barriers and the natural, undisturbed state at the time of beginning of excavation for the repository for the geosphere and the biosphere. The repository system is based on the KBS-3 method, where copper canisters with a cast iron insert containing spent nuclear fuel are surrounded by bentonite clay and deposited at approximately 500 m depth in saturated, granitic rock. For the purpose of the safety assessment the engineered portion of the repository system has been divided into a number of consecutive barriers or sub-systems. The importance of a particular feature for safety has influenced the resolution into components. In principle, components close to the source term and those that play an important role for safety are treated in more detail than more peripheral components. For the option with 40 years of reactor operation, the quantity of BWR fuel is estimated at 7200 tonnes and the quantity of PWR fuel at 2300 tonnes. The fuel burn-up may vary from 15 MWd/kgU up to 60 MWd/kg. Geometric aspects of the fuel cladding tubes of importance in the safety assessment are, as a rule, handled sufficiently pessimistically in analyses of radionuclide transport that differences between different fuel types are irrelevant. The relative differences in radionuclide inventory with respect to burn-up are small. Deviations in inventory and deviating or damaged fuel are not considered in the SR-Can interim reporting but will be handled in the final reporting of SR-Can. The canister consists of an inner container, the insert of cast iron and an outer shell of copper. The cast iron insert provides mechanical stability and the copper shell protects against corrosion in the repository environment. The copper shell is 5 cm thick and

  15. Identification and assessment of organisational factors related to the safety of NPPs - State-of-the-Art Report

    International Nuclear Information System (INIS)

    The initiation of this State-of-the-Art Report (SOAR) on Organisational Factors Identification and Assessment comes from operating experience associated with a number of major events world-wide which caused power plants to be shutdown for a significant period of time. Root cause assessments of these events identified weaknesses in organisational factors as contributing to these events. There is general recognition that organisational factors need to be evaluated for their contribution to plant safety performance and risk to prevent their recurrence in events. There is a need to collect and analyse operational and event data from the nuclear environment to determine the safety and risk significance of organisational factors, to identify assessment methods for those factors, and to gain peer review of the results to ensure credibility and acceptability of these methods and possibly their measures. The SOAR presents a representative view of developments in this field and addresses the following topics: - identification of organisational factors; - identification of methods for the evaluation of organisational factors; - identification of methods for the evaluation of whole organisations; - identification of gaps in knowledge and needed research to evaluate adequately the influence of organisation and management on safety and risk. The workshop participants identified 12 organisational factors as important to assess in determining organisational safety performance. They are: external influences; goals and strategies; management functions and overview; resource allocation; human resource management; training; co-ordination of work; organisational knowledge; proceduralization; organisational culture; organisational learning; and communication. Different cultural backgrounds of participants using their own terminology sometimes made it difficult to have a common definition for certain factors. Some factors could be defined by consensus; other factors such as

  16. The Colorado Climate Preparedness Project: A Systematic Approach to Assessing Efforts Supporting State-Level Adaptation

    Science.gov (United States)

    Klein, R.; Gordon, E.

    2010-12-01

    Scholars and policy analysts often contend that an effective climate adaptation strategy must entail "mainstreaming," or incorporating responses to possible climate impacts into existing planning and management decision frameworks. Such an approach, however, makes it difficult to assess the degree to which decisionmaking entities are engaging in adaptive activities that may or may not be explicitly framed around a changing climate. For example, a drought management plan may not explicitly address climate change, but the activities and strategies outlined in it may reduce vulnerabilities posed by a variable and changing climate. Consequently, to generate a strategic climate adaptation plan requires identifying the entire suite of activities that are implicitly linked to climate and may affect adaptive capacity within the system. Here we outline a novel, two-pronged approach, leveraging social science methods, to understanding adaptation throughout state government in Colorado. First, we conducted a series of interviews with key actors in state and federal government agencies, non-governmental organizations, universities, and other entities engaged in state issues. The purpose of these interviews was to elicit information about current activities that may affect the state’s adaptive capacity and to identify future climate-related needs across the state. Second, we have developed an interactive database cataloging organizations, products, projects, and people actively engaged in adaptive planning and policymaking that are relevant to the state of Colorado. The database includes a wiki interface, helping create a dynamic component that will enable frequent updating as climate-relevant information emerges. The results of this project are intended to paint a clear picture of sectors and agencies with higher and lower levels of adaptation awareness and to provide a roadmap for the next gubernatorial administration to pursue a more sophisticated climate adaptation agenda

We describe an example of institutionalization in the United States through Alaska's early experience with institutionalization of HIA. Literature review . HIA arose from a series of health conferences in the 1970s that affirmed the importance of “health for all.” A number of key milestones eventually defined HIA as a unique field of impact assessment. There are several approaches to institutionalization, and one common approach in the United States is through the National Environmental Policy Act (NEPA. NEPA formed the basis for the earliest HIAs in Alaska. Program description . Early HIAs in Alaska led to conferences, working groups, a state guidance document and the institutionalization of a HIA program within the Department of Health and Social Services in 2010. A medical epidemiologist staffs the program, which utilizes contractors to meet rising demand for HIA. The HIA program has sustainable funding from the state budget and from the state's natural resource permitting process. The HIA document is the main deliverable, but the program performs other tasks, including fieldwork and technical reviews. The HIA program works closely with a host of collaborative partners. Conclusion . Alaska's institutionalized HIA program benefits from sustainable funding that promotes continuous quality improvement and involves the program in the entire life cycle of a development project. The program structure adapts well to variations in workflow and supports a host of quality control activities. Currently, the program focuses on HIAs for natural resource development projects.

  18. Community, State, and Federal Approaches to Cumulative Risk Assessment: Challenges and Opportunities for Integration

    2015-04-01

    Full Text Available Community, state, and federal approaches to conventional and cumulative risk assessment (CRA were described and compared to assess similarities and differences, and develop recommendations for a consistent CRA approach, acceptable across each level as a rigorous scientific methodology, including partnership formation and solution development as necessary practices. Community, state, and federal examples were described and then summarized based on their adherence to CRA principles of: (1 planning, scoping, and problem formulation; (2 risk analysis and ranking, and (3 risk characterization, interpretation, and management. While each application shared the common goal of protecting human health and the environment, they adopted different approaches to achieve this. For a specific project-level analysis of a particular place or instance, this may be acceptable, but to ensure long-term applicability and transferability to other projects, recommendations for developing a consistent approach to CRA are provided. This approach would draw from best practices, risk assessment and decision analysis sciences, and historical lessons learned to provide results in an understandable and accepted manner by all entities. This approach is intended to provide a common ground around which to develop CRA methods and approaches that can be followed at all levels.

    [This paper is part of the Focused Collection on Upper Division Physics Courses.] Standardized assessment tests that allow researchers to compare the performance of students under various curricula are highly desirable. There are several research-based conceptual tests that serve as instruments to assess and identify students' difficulties in lower-division courses. At the upper-division level assessing students' difficulties is a more challenging task. Although several research groups are currently working on such tests, their reliability and validity are still under investigation. We analyze the results of the Colorado Upper-Division Electrostatics diagnostic from Oregon State University and compare it with data from the University of Colorado. In particular, we show potential shortcomings in the Oregon State University curriculum regarding separation of variables and boundary conditions, as well as uncover weaknesses of the rubric to the free-response version of the diagnostic. We also demonstrate how the diagnostic can be used to obtain information about student learning during a gap in instruction. Our work complements and extends the previous findings from the University of Colorado by highlighting important differences in student learning that may be related to the curriculum, illuminating difficulties with the rubric for certain problems and verifying decay in post-test results over time.

  20. Phytotoxic risk assessment of ambient air pollution on agricultural crops in Selangor State, Malaysia

    International Nuclear Information System (INIS)

    The phytotoxic risk of ambient air pollution to local vegetation was assessed in Selangor State, Malaysia. The AOT40 value was calculated by means of the continuously monitored daily maximum concentration and the local diurnal pattern of O3. Together with minor risks associated with the levels of NO2 and SO2, the study found that the monthly AOT40 values in these peri-urban sites were consistently over 1.0 ppm.h, which is well in exceedance of the given European critical level. Linking the O3 level to actual agricultural crop production in Selangor State also indicated that the extent of yield losses could have ranged from 1.6 to 5.0% (by weight) in 2000. Despite a number of uncertainties, the study showed a simple but useful methodological framework for phytotoxic risk assessment with a limited data set, which could contribute to appropriate policy discussion and countermeasures in countries under similar conditions. - There is a large potential of phytotoxic risk on vegetation in Selangor State, Malaysia

    Effective planning for community health partnerships requires understanding how initial readiness-that is, contextual factors and capacity-influences implementation of activities and programs. This study compares the context and capacity of drug and violence prevention coalitions in Mexico to those in the United States. Measures of coalition context include community problems, community leadership style, and sense of community. Measures of coalition capacity include the existence of collaborative partnerships and coalition champions. The assessment was completed by 195 members of 9 coalitions in Mexico and 139 members of 7 coalitions in the United States. Psychometric analyses indicate the measures have moderate to strong internal consistency, along with good convergent and discriminant validity in both settings. Results indicate that members of Mexican coalitions perceive substantially more serious community problems, especially with respect to education, law enforcement, and access to alcohol and drugs. Compared to respondents in the United States, Mexican respondents perceive sense of community to be weaker and that prevention efforts are not as valued by the population where the coalitions are located. The Mexican coalitions appear to be operating in a substantially more challenging environment for the prevention of violence and substance use. Their ability to manage these challenges will likely play a large role in determining whether they are successful in their prevention efforts. The context and capacity assessment is a valuable tool that coalitions can use in order to identify and address initial barriers to success. PMID:26205249

  2. Plant-wide quantitative assessment of a process industry system's operating state based on color-spectrum

    2015-08-01

    This paper presents a general theoretical framework to assess the operating state of a process industry system quantitatively based on meshing the theory of scientific data visualization and digital image processing. First, a series of color-spectrum, which represent the operating state of the system, is formed by mapping the monitor data set to a group of digital color images. Second, the common feature of color-spectrum, which is named benchmark-color-spectrum, is extracted as a standard of the normal state. Third, the abnormal degree can be quantified by calculating the difference of the benchmark-color-spectrum with observed color-spectrum. At last, a plant-wide operating state of the system in a period of time can be shown by plotting quantitative abnormal degree. Two case is included to illustrate the proposed method and its appropriateness. One is a general process industry system simulator named Tennessee Eastman Process. Another is an air compressor group which belongs to a real chemical plant.

We used the last version of the code without major changes for these exercises in order to properly obtain the keys for the improvement of BaCo. (author)

  5. Successful global assessments and monitoring: The roles of the international community and the United States

    International Nuclear Information System (INIS)

    Successful global assessments and monitoring of natural resources requires teamwork between participating nations and the international communities charged with the responsibility for collecting and disseminating information. In an attempt to identify emerging information needs and to promote coordination, the International Union of Forestry Research Organizations (IUFRO) and other national and international groups held a major conference and workshop in Venice, Italy, on global monitoring last September. The results of the meeting and subsequent events in Montreal indicated a need for more aggressive leadership at the international level and more cooperation at the national level. This paper reports on the outcome of the Venice conference and list some things that the international community and the United States must do to make global assessments and monitoring a reality

  6. State-of-the-art and research needs for oil spill impact assessment modelling

    International Nuclear Information System (INIS)

    Many oil spill models focus on trajectory and fate in aquatic environments. Models designed to address subsurface oil concentrations typically overlay fates model concentration results on maps or grids of biological distributions to assess impacts. This paper discussed a state-of-the-art biological effects model designed to evaluate the impacts and dose of oil spill hydrocarbons on aquatic biota including birds, mammals, reptiles, fish, invertebrates and plants. The biological effects model was coupled to an oil trajectory and fates spill impact model application package (SIMAP) in order to obtain accurate spatial and temporal quantifications of oil distributions and hydrocarbon component concentrations. Processes simulated in the model included slick spreading, evaporation of volatiles from surface oil, transport on the water surface, and various types of oil dispersion and emulsification. The design of the model was discussed, as well as strategies used for applying the model for hindcasts and risk assessments. 204 refs., 3 tabs., 5 figs

    Background: Despite the continued growth of Health Impact Assessment (HIA) in the US, there is little research on HIA capacity-building. A comprehensive study of longer-term training outcomes may reveal opportunities for improving capacity building activities and HIA practice. Methods: We conducted in-depth interviews with HIA trainees in the United States to assess their outcomes and needs. Using a training evaluation framework, we measured outcomes across a spectrum of reaction, learning, behavior and results. Results: From 2006 to 2012, four organizations trained over 2200 people in at least 75 in-person HIA trainings in 29 states. We interviewed 48 trainees, selected both randomly and purposefully. The mean duration between training and interview was 3.4 years. Trainees reported that their training objectives were met, especially when relevant case-studies were used. They established new collaborations at the trainings and maintained them. Training appeared to catalyze more holistic thinking and practice, including a range of HIA-related activities. Many trainees disseminated what they learned and engaged in components of HIA, even without dedicated funding. Going forward, trainees need assistance with quantitative methods, project management, community engagement, framing recommendations, and evaluation. Conclusions: The research revealed opportunities for a range of HIA stakeholders to refine and coordinate training resources, apply a competency framework and leverage complimentary workforce development efforts, and sensitize and build the capacity of communities. - Highlights: • We interviewed HIA trainees in the United States to assess longer-term outcomes. • Training appeared to catalyze a range of beneficial partnerships and activities. • Trainees reported outstanding needs for specific skills and competencies. • There are various opportunities to improve training and capacity-building.

  11. Present state of quantum supergravity

    International Nuclear Information System (INIS)

    This is a brief summary of the review talk given at the Seminar. The accent was made on the results of the last three years. The talk consisted of the four parts: 1. Ordinary N ≤ 8 supergravities in D = 4 dimensions; 2. Higher dimensional D ≤ 11 supergravities; 3. Conformal (N = 4, D = 4) supergravities; 4. Superstring theory (D = 10). The main conclusion of the first part was that in spite of a number of interesting quantum properties (cancellation of one- and two-loop infinities on the mass shell, cancellation of quartic and quadractic infinities, etc.) ordinary (gauged) supergravities cannot be seriously considered as candidates for a fundamental unified theory valid at arbitrarily small distances. The reason is in the dimensional nature of gravitational coupling constant, i.e. in the presence of the infinite number of invariants which may formally appear as infinites at three and higher loops. It is very unlikely that the infinite number of coefficients of these invariants in the effective action may appear to be vanishing in a theory with a finite number of fields and finite dimensional symmetry group

  12. Probabilistic safety assessment to 1000 MW PWR plant during shutdown state

    International Nuclear Information System (INIS)

    This paper initiates a study focused on level 1 Probability Safety Assessment (PSA) for shutdown operation at 1000 MWe PWR. Shutdown PSA models considering different plant outage types are constructed respectively to evaluate the risk of LOI-RRA operation. The application of SPAR-X-method is also evaluated. The results show that the potential risk during shutdown should not be ignored; PSA for shutdown states could help to prompt the improvement in procedure to reduce the risk in shutdown condition. Going through the LOI-RRA operation at cool shutdown refueling outage significantly increases the plant risk; the dominant factor contributing to CDF is human error. (authors)

  13. The state-of-the-art for seismic design of nuclear power plants. An assessment

    International Nuclear Information System (INIS)

    Applied Nucleonics Company (ANC) has recently completed an independent assessment of the state-of-the-art of seismic design. Besides the state-of-the-art evaluation, ANC has delineated areas of research in seismic design and analysis which require further work. Three general areas were investigated: soils, siting and seismic ground motion specification; soil-structure interaction; and the response of major nuclear power plant structures and components. Major findings include the necessity of improving knowledge of seismicity and soil dynamic parameters; improved specification of seismic inputs used for design (the Safe Shutdown Earthquake (SSE) and Operating Basis Earthquake (OBE)) and validation of models and methods used for soil-structure interaction calculations. Also considered important are the acquisition of additional experimental and test data on equipment and structures; certain changes to Regulations and Standards; and the development of simplified design methods suitable for industry-wide application

    The greatest weakness in existing design strategies for brittle fracture is in the narrow range of conditions for which the strategies are adequate. The primary reason for this weakness is the use of simplistic mechanical models of fracture processes and unverified statistical models of materials. To improve the design methodology, the models must first be improved. Specifically recommended research goals are: to develop models of cracks with realistic geometry under arbitrary stress states; to identify and model the most important relationships between fracture processes and microstructural features; to assess the technology available for acquiring statistical data on microstructure and flaw populations, and to establish the amount of data required for verification of statistical models; and to establish a computer-based fracture simulation that can incorporate a wide variety of mechanical and statistical models and crack geometries, as well as arbitrary stress states. 204 refs., 2 tabs.

    Policy makers will most likely need to make decisions about climate policy before climate scientists have resolved all relevant uncertainties about the impacts of climate change. This study demonstrates a risk-assessment methodology for evaluating uncertain future climatic conditions. We estimate the impacts of climate change on U.S. state- and national-level economic activity from 2010 to 2050. To understand the implications of uncertainty on risk and to provide a near-term rationale for policy interventions to mitigate the course of climate change, we focus on precipitation, one of the most uncertain aspects of future climate change. We use results of the climate-model ensemble from the Intergovernmental Panel on Climate Change's (IPCC) Fourth Assessment Report 4 (AR4) as a proxy for representing climate uncertainty over the next 40 years, map the simulated weather from the climate models hydrologically to the county level to determine the physical consequences on economic activity at the state level, and perform a detailed 70-industry analysis of economic impacts among the interacting lower-48 states. We determine the industry-level contribution to the gross domestic product and employment impacts at the state level, as well as interstate population migration, effects on personal income, and consequences for the U.S. trade balance. We show that the mean or average risk of damage to the U.S. economy from climate change, at the national level, is on the order of $1 trillion over the next 40 years, with losses in employment equivalent to nearly 7 million full-time jobs.

    Full Text Available This paper shows an empirical assessment of social unrest dynamics in the Eurasian countries. We use a big database of social events (GDELT to build up several real time indexes of social unrest escalation by social agents divided in several stages consistent with the Unrest Lifecycle Theory (vindication, protest and conflict and alternatives measures of state response (repression and cooperation. We build a Vector Autoregressive (VAR model to analyse the unrest dynamic cycle of social agents and state response. Our results show that Eurasia is a fairly volatile region in what shock-generation and inertia relates. Social reactivity is also relevant but we find that this is stronger at the initial stages of unrest while it decays as the intensity of shocks increases. Repressive state response is a fact but it decays too in intensity as the conflict escalates along the unrest cycle, falling even into an accommodative mode. We attribute this behaviour to the limited state enforcing ability of among other things. Unrest and government action are not homogenous across the region, West and Central Eurasia are more prone to conflict escalation and their enforcing ability of the state is also lower. This gives an insight were prevalent unrest theories such as unrest lifecycle; deterrence and backslash seem more dominant. We also find traces of spill over-effects or contagion among countries who share boundaries but the intensity and sign is undefined. We compare these stylized facts against the MENA region and suggest that Eurasia carries similar though milder dynamics in all terms, volatility and reactivity of social unrest, state response and enforcing inability and contagion.

    Full Text Available The study assessed risk in the Internally Generated Revenue structure of Abia State, Nigeria. The specific objectives included (I estimation of factors and significant input variables influencing risk in IGR structure of the State and (II examination of risk reducing practices. Data which were collected from 50 management staffs of revenue yielding Ministries, departments and agencies in Abia State were analysed with factor analysis, Tobit regression analysis and descriptive statistics. The results of the factor analysis grouped the significant input variables which scored 0.33 and above into institutional and non-institutional sources of risk while that of Tobit regression analysis revealed that significant variables which cause variation between expected and realised IGR of the State are lack of database; mismanagement of fund by government; delay in payment of revenue by tax payers; difficulty in tracking tax evaders; and weak internal control mechanism. The results point to the fact that policy on tax identification number (TIN should be strengthened and linked to the bank account of the tax payer so that relevant revenues are deducted at source.

    This report evaluates a newly-available, high-definition, video camera coupled with a zoom optical system for microscopic imaging of micro-electro-mechanical systems. We did this work to support configuration of three document-camera-like stations as part of an installation in a new Microsystems building at Sandia National Laboratories. The video display walls to be installed as part of these three presentation and training stations are of extraordinary resolution and quality. The new availability of a reasonably-priced, cinema-quality, high-definition video camera offers the prospect of filling these displays with full-motion imaging of Sandia's microscopic products at a quality substantially beyond the quality of typical video microscopes. Simple and robust operation of the microscope stations will allow the extraordinary-quality imaging to contribute to Sandia's day-to-day research and training operations. This report illustrates the disappointing image quality from a camera/lens system comprised of a Sony HDC-X310 high-definition video camera coupled to a Navitar Zoom 6000 lens. We determined that this Sony camera is capable of substantially more image quality than the Navitar optic can deliver. We identified an optical doubler lens from Navitar as the component of their optical system that accounts for a substantial part of the image quality problem. While work continues to incrementally improve performance of the Navitar system, we are also evaluating optical systems from other vendors to couple to this Sony camera.

    The major resources used by the Bureau of Environment, and Environmental Epidemiology (EEP) for risk assessment are: the Integrated Risk Information System (IRIS), Health and Environmental Effects Summary Table (HEAST), Agency for Toxic Substances and disease Registry (ATSDR) Toxicological Profiles, databases at the National Library of Medicine (NLM), World Health Organization (WHO) ENvironmental Criteria, and documents that the Environmental Protection Agency (EPA) has published on Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) risk assessment activities. The Risk Assessment Review has been helpful in providing information about availability of new documents or information. No systematic method has been made available to us to locate information resources. IRIS User`s Support has been helpful in making appropriate and timely referrals. Most other EPA resources were located by serendipity and persistence. The CERCLA methodology for risk assessments is being used in environmental programs, and at present, one person is responsible for all risk assessment activities in the department, but plans are underway to train one or two people from each program area. 2 figs.

  1. Identification and assessment of organisational factors related to the safety of NPPs - State-of-the-Art Report

    International Nuclear Information System (INIS)

    The initiation of this State-of-the-Art Report (SOAR) on Organisational Factors Identification and Assessment comes from operating experience associated with a number of major events world-wide which caused power plants to be shutdown for a significant period of time. Root cause assessments of these events identified weaknesses in organisational factors as contributing to these events. There is general recognition that organisational factors need to be evaluated for their contribution to plant safety performance and risk to prevent their recurrence in events. A special recommendation to create a SOAR was presented in the NEA report on Research Strategies for Human Performance [NEA/CSNI/R(97)24]. Based on this recommendation the Principle Working Group 1 (PWG1) requested, as a top priority, that the Expanded Task Force (ETF) on Human Factors develop a SOAR for the September 1998 meeting. The ETF members were aware that it was a challenging topic. The field of organisational behaviour is not yet fully developed for the nuclear organisation. There is a need to collect and analyse operational and event data from the nuclear environment to determine the safety and risk significance of organisational factors, to identify assessment methods for those factors, and to gain peer review of the results to ensure credibility and acceptability of these methods and possibly their measures. This SOAR reports on the results of the workshop on Organisational Factors Identification and Assessment held in Boettstein Castle, Switzerland, on 14-19 June 1998. Twenty-eight participants from twelve Member countries and Russia represented three different environments: nuclear utilities; regulatory bodies and inspectorates; and the research and academic community. The various approaches discussed in the SOAR reflect the perspective of these entities. The SOAR addresses the following topics: - identification of organisational factors; - identification of methods for the evaluation of

    Full Text Available Background : Chronic damage to the central nervous system resulting in cognitive impairment has been shown with repeated, low doses of organophosphorus (OP exposure over month or years. Aim: The study aimed to find out whether there is any cognitive impairment following acute OP exposure that could be detected by a simple screening instrument, the Mini Mental State Examination (MMSE, in clinical settings. Settings and Design: A cohort study. Materials and Methods: The study was conducted with matched controls. Consecutive patients admitted to the hospital with acute ingestion of OP were recruited. Cognitive function was assessed with the MMSE, digit span test, test of long-term memory function and concentration. Patients were assessed twice: at 1 and 6 weeks of exposure. Statistical Analysis: Continuous variables were analyzed with the paired and unpaired T-tests. Non-normally distributed data were analyzed with the Mann-Whitney U test and Wilcoxon Signed Rank test. Discrete variables were analyzed with the Chi-square test. Results: There were 60 patients and 61 controls. The mean age (SD of the patients and controls was 31.5 (11.6 and 31.3 (11.8 years, respectively. Forty-two patients turned up for the second assessment. Significant impairment of cognitive function was seen in the total score of MMSE (95% CI -2.5 to -0.3, orientation (95% CI -1 to -0.2 and language (95% CI -0.9 to -0.1 domains of MMSE, digit span test (95% CI 0.1-1.7 and test of long-term memory function (95% CI 0.3-2.3 in the first assessment compared with the controls. When the results of the second assessment were compared with the controls, no significant differences were seen. Conclusion: Although there was a slight transient cognitive impairment detected with the screening tests following acute OP ingestion, no long-term cognitive defects was detected.

  5. Using safety assessment techniques to build confidence in repository performance: The United States experience

    International Nuclear Information System (INIS)

    The United States Department of Energy (US DOE) has prepared detailed safety assessments (called performance assessments or total system performance assessments in the US regulations and practice) during the last 20 years for two deep geologic repositories for the disposal of radioactive wastes: the Waste Isolation Pilot Plant (WIPP) in south-eastern New Mexico, and the proposed Yucca Mountain repository in Nevada for spent nuclear fuel and high-level radioactive waste. The DOE is currently conducting generic safety assessment analyses of disposal concepts that are potentially viable alternatives for the US in the future, and anticipates that performance assessments will continue to be an important part of the process of evaluating the suitability of disposal alternatives. For both the WIPP and the proposed Yucca Mountain repository, the performance assessment was an essential part of the DoE's application to the regulator, which in the US serves the same function as the safety case as defined by the international radioactive waste disposal community (OECD/NEA, 2004). For both sites, performance assessments provided quantitative estimates of the long-term performance of the disposal system (10 000 years for WIPP and 1 000 000 years for Yucca Mountain), and at both sites the performance assessments matured through a series of iterations over a decade or more, with increasing sophistication in the data, models and methods used in the analyses. Current performance assessment analyses for hypothetical generalised disposal systems build on the experience gained from both the WIPP and Yucca Mountain programmes, and, although they are unavoidably simplified compared to those done for specific sites, they use the same basic approaches. Confidence in the overall long-term safety of a disposal system comes through a sound understanding of the geologic and engineered barriers relied on to isolate the waste. Performance assessments can contribute to this confidence in multiple

    The Florida Gap (FI-Gap) project provides an assessment of the degree to which native animal species and natural communities are or are not represented in existing conservation lands. Those species and communities not adequately represented in areas being managed for native species constitute 'gaps' in the existing network of conservation lands. The United States Geological Survey Gap Analysis Program is a national effort and so, eventually, all 50 states will have completed it. The objective of FI-Gap was to provide broad geographic information on the status of terrestrial vertebrates, butterflies, skippers and ants and their respective habitats to address the loss of biological diversity. To model the distributions and potential habitat of all terrestrial species of mammals, breeding birds, reptiles, amphibians, butterflies, skippers and ants in Florida, natural land cover was mapped to the level of dominant or co-dominant plant species. Land cover was classified from Landsat Thematic Mapper (TM) satellite imagery and auxiliary data such as the national wetlands inventory (NWI), soils maps, aerial imagery, existing land use/land cover maps, and on-the-ground surveys, Wildlife distribution models were produced by identifying suitable habitat for each species within that species' range, Mammalian models also assessed a minimum critical area required for sustainability of the species' population. Wildlife species richness was summarized against land stewardship ranked by an area's mandates for conservation protection. ?? 2002 Elsevier Science Ltd. All rights reserved.

    A methodological approach and results on water resources assessment in large areas are described with the case study of Ceará State (148,016 km2, northeast Brazil), where the scarceness of water resources is one of the main challenges in territorial planning and development. This work deals with the quantification and the mapping of water resources potential, being part of methodological approaches applied to the quantification of hydric diversity and geodiversity. Water resources potential is here considered as the sum of the hydric elements rainfall, groundwater specific discharge, water reservoirs, and river hierarchy. The assessment was based in a territorial organization by drainage sub-basins and in vector maps generated and treated with GIS software. Rainfall, groundwater specific discharge and hydrographical data were obtained in official institutions and allowed the construction of the annual mean rainfall map for a forty year period (1974-2014), the annual mean groundwater specific discharge map for a thirty-four year period, and the river and drainage basin hierarchy maps. These delivered rainfall, groundwater specific discharge, water reservoirs and river hierarchy partial indices expressed on quantitative maps with normalized values distributed by level 3 drainage basins. The sum of the partial indices originated the quantitative map of water resources potential index and by the Gaussian interpolation of this quantitative data a map of hydric diversity in Ceará state was created. Therefore, the water resources potential index is higher in 4 regions of the state (Noroeste Cearense, Zona Metropolitana de Fortaleza e da Zona Norte, Vale do Jaguaribe and Zonas Centro-sul e Sul Cearense). The index is low or very low in the whole region of Sertões Cearenses, confirming the important role of climatic features in hydrological diversity. Water resources management must consider technical tools for water resources assessment, in the line of other methods for

  8. Assessment of the economic impacts of porcine epidemic diarrhea virus in the United States.

    Porcine epidemic diarrhea virus (PEDV), which first emerged in the United States in 2013, spread throughout the U.S. hog population. Limited preemptive knowledge impeded the understanding of PEDV introduction, spread, and prospective economic impacts in the United States. To assess these impacts, this article reviews the timeline of PEDV in the United States and the corresponding impacts. PEDV is a supply-impacting disease and is not demand inhibiting, as pork demand remained strong since PEDV first appeared. Pig losses reached significant levels during September 2013 through August 2014, with the majority of pork production impacts occurring in 2014. PEDV had differing impacts for subsectors of the pork industry. A budget model demonstrates that producers could have had pig losses and decreases in productivity proportionally smaller than price increases, resulting in net returns above what was expected before the major outbreak of PEDV. Previous literature is reviewed to identify the potential main industry beneficiaries of the PEDV outbreaks in the United States. As a result of reduced volumes of available pig and hog supplies, reductions in annual returns likely occurred for packers, processors, distributors, and retailers. In addition, pork consumers who experienced reduced-supply-induced pork-price increases were likely harmed directly by higher prices paid for pork and indirectly as prices of competing meats were also likely strengthened by PEDV. This article also identifies future considerations motivated by the appearance of PEDV in the United States, such as discussions of industry-wide efficiency and competitive advantage, the future role of PEDV vaccines, enhancement in biosecurity measures, and consumer perceptions of food safety and insecurity.

    Exploitation of coal seams in the Upper Silesian Coal Basin is conducted in complex and difficult conditions. These difficulties are connected with the occurrence of many natural mining hazards and limitations resulting from the existing in this area surface infrastructure. One of the most important problems of Polish mining is the rock burst hazard and reliable evaluation of its condition. During long-years' mining practice in Poland a comprehensive system of evaluation and control of this hazard was de-veloped. In the paper the main aspects of rock burst hazard state evaluation will be presented, comprising: 1) rock mass inclination for rock bursts, I.e., rock strength properties investigation, comprehensive parametric evaluation of rock mass inclination for rock bursts, prognosis of seismic events induced by mining operations, methods of computer-aided modelling of stress and rock mass deformation parameters distribution, strategic rock mass classification under rock burst degrees; 2) immediate seismic and rock burst hazard state evaluation, I.e., low diameter test drilling method, seismologic and seismoacoustic method, comprehensive method of rock burst hazard state evaluation, non-standard methods of evaluation; 3) legal aspects of rock burst hazard state evaluation. Selected elements of the hazard state evaluation system are illustrated with specific practical examples of their applica-tion.

    Full Text Available In recent times, many zoonotic diseases have emerged with serious negative consequences on humans. In the light of this, ante-mortem inspections were conducted, using body condition scoring to assess the health status of livestock presenting for slaughter, and to identify issues relating to meat inspection in four purposively selected government approved abattoirs in Benue State, Nigeria. The result of our assessment showed that 5.0% of the cattle and goats presented for slaughter during the investigation period were highly emaciated animals with a prevalence range of 0.0–12.1% with variance between abattoirs, whereas 37.9% were moderately emaciated and 57.2% had good body condition. Extreme emaciation was higher in cattle (6.7% compared to the goats (3.2%. The moderately high prevalence of emaciated animals intended for human consumption coupled with unorganized and inappropriate meat inspection in the studied abattoirs has serious public health implications. To prevent consumers from contacting zoonotic diseases, education of butchers and traders is necessary for thorough and effective inspections. In addition, animal traders should be encouraged to seek veterinary assistance for their sick animals. Meat inspectors should treat all emaciated animals as suspects, as emaciation could be a cause from underlying health problems.

  13. Technology assessment of vertical and horizontal air drilling potential in the United States. Final report

    The objective of the research was to assess the potential for vertical, directional and horizontal air drilling in the United States and to evaluate the current technology used in air drilling. To accomplish the task, the continental United States was divided into drilling regions and provinces. The map in Appendix A shows the divisions. Air drilling data were accumulated for as many provinces as possible. The data were used to define the potential problems associated with air drilling, to determine the limitations of air drilling and to analyze the relative economics of drilling with air versus drilling mud. While gathering the drilling data, operators, drilling contractors, air drilling contractors, and service companies were contacted. Their opinion as to the advantages and limitations of air drilling were discussed. Each was specifically asked if they thought air drilling could be expanded within the continental United States and where that expansion could take place. The well data were collected and placed in a data base. Over 165 records were collected. Once in the data base, the information was analyzed to determine the economics of air drilling and to determine the limiting factors associated with air drilling.

  14. A state-of-the-art methodology for impact assessment of covered uranium mill tailings

    International Nuclear Information System (INIS)

    An impact assessment methodology is being developed that integrates several advanced modelling and characterisation techniques for the purpose of assessing the current and future environmental and health impact of a surface repository containing wastes from uranium milling and radium processing. The former radium processing plant at Olen, Belgium, accumulated during nearly half a century considerable amounts of radium-containing wastes. Also present at the site are uranium mill tailings. These wastes were disposed of in a heavily engineered surface repository at the occasion of a remediation plan carried out in the mid eighties. The repository contains several concrete bunkers covered with a multi-layer hydraulic barrier. In the current impact assessment study the only exposure pathway discussed is by contamination of groundwater. For this purpose we calculated variably-saturated water flow in the multi-layer barrier and the underlying waste zones and used geochemical modelling to estimate the chemical species and their solubility's in the aqueous phase of the various waste forms. The assessment further includes modelling of contaminant leaching from the tailings towards the groundwater, contaminant transport in the surrounding groundwater towards a water well, and evaluation of the doses for ingestion, inhalation and external irradiation resulting from use of groundwater from the well. Details of the waste and site characterisation as well as contaminant modelling are discussed. (author)

  19. Weed risk assessment for aquatic plants: modification of a New Zealand system for the United States.

    Directory of Open Access Journals (Sweden)

    Doria R Gordon

    Full Text Available We tested the accuracy of an invasive aquatic plant risk assessment system in the United States that we modified from a system originally developed by New Zealand's Biosecurity Program. The US system is comprised of 38 questions that address biological, historical, and environmental tolerance traits. Values associated with each response are summed to produce a total score for each species that indicates its risk of invasion. To calibrate and test this risk assessment, we identified 39 aquatic plant species that are major invaders in the continental US, 31 species that have naturalized but have no documented impacts (minor invaders, and 60 that have been introduced but have not established. These species represent 55 families and span all aquatic plant growth forms. We found sufficient information to assess all but three of these species. When the results are compared to the known invasiveness of the species, major invaders are distinguished from minor and non-invaders with 91% accuracy. Using this approach, the US aquatic weed risk assessment correctly identifies major invaders 85%, and non-invaders 98%, of the time. Model validation using an additional 10 non-invaders and 10 invaders resulted in 100% accuracy for the former, and 80% accuracy for the latter group. Accuracy was further improved to an average of 91% for all groups when the 17% of species with scores of 31-39 required further evaluation prior to risk classification. The high accuracy with which we can distinguish non-invaders from harmful invaders suggests that this tool provides a feasible, pro-active system for pre-import screening of aquatic plants in the US, and may have additional utility for prioritizing management efforts of established species.
