    The development of a tool to assess the quality of indoor air for buildings in the residential and commercial sector was presented. The computer software program was designed to allow a building operator to set an optimal target to reflect the greatest economies in energy consumption. Air quality was assessed in terms of carbon dioxide, volatile organic compounds, and other common indoor pollutants

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

    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.)

    Beyea, J.

    1990-01-01

    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

    Unlike other techniques, nuclear cardiologic imaging enables evaluation of cardiac function employing radioactive tracers. This procedure can be used to assess myocardial blood flow, metabolism, viability, cardiac innervation and receptor status. Therefore, this noninvasive imaging modality can be regarded as supplementary to the screening methods in cardiology and also to angiography. General clinical use was not possible until the rapid development of nuclear medicine in the fifties began. With increasing wide-spread of positron emission tomography more detailed information on metabolic tissue characterization can be expected and will be of enormous relevance in clinical decision making and in selecting patients for interventions.

    solicited to construct these scenarios.The methods for mapping the current LULC and ecosystem disturbances will require the extensive use of both remote-sensing data and field-survey data (for example, forest inventories) to capture and characterize landscape-changing events. For potential LULC changes and ecosystem disturbances, key drivers such as socioeconomic and climate changes will be used in addition to the biophysical data. The result of these analyses will be a series of maps for each future year for each scenario. These annual maps will form the basis for estimating carbon storage and GHG emissions. For terrestrial ecosystems, carbon storage, carbon-sequestration capacities, and GHG emissions under the present conditions and future scenarios will be assessed using the LULC-change and ecosystem-disturbance estimates in map format with a spatially explicit biogeochemical ensemble modeling system that incorporates properties of management activities (such as tillage or harvesting) and properties of individual ecosystems (such as energy exchange, vegetation characteristics, hydrological cycling, and soil attributes). For aquatic ecosystems, carbon burial in sediments and fluxes of GHG are functions of the present and future potential stream flow and sediment transport and will be assessed using empirical hydrological modeling methods. Validation and uncertainty analysis methods described in the methodology will follow established guidelines to assess the quality of the assessment results.The U.S. Environmental Protection Agency’s Level II ecoregions map will be the practical instrument for developing and delivering assessment results. Consequently, the ecoregion (there are 22 modified ecoregions) will be the reporting unit of the assessment because the scenarios, assessment results, validation, and uncertainty analysis will be produced at that scale. The implementation of these methods will require collaborations among various Federal agencies, State agencies

    Separate, extended series of positive, negative, and neutral pictures were presented to 24 (12 men, 12 women) undergraduates. Each series was presented on a different day, with full counterbalancing of presentation orders. Affective state was measured using (a) orbicularis oculi activity in response to acoustic startle probes during picture presentation, (b) corrugator supercilii activity between and during picture presentation, and (c) changes in self-reports of positive and negative affect. Participants exhibited larger eyeblink reflex magnitudes when viewing negative than when viewing positive pictures. Corrugator activity was also greater during the negative than during the positive picture set, during both picture presentation and the period between pictures. Self-reports of negative affect increased in response to the negative picture set, and self-reports of positive affect were greatest following the positive picture set. These findings suggest that extended picture presentation is an effective method of manipulating affective state and further highlight the utility of startle probe and facial electromyographic measures in providing on-line readouts of affective state.

    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

    A special determination method allowed to confirm the transferability of fracture mechanics parameters for crack initiation. A correlation was found between notch impact energy and crack initiation value for the higher shelf of toughness. Carrying and deformation behaviour of components can be determined when stress condition and multi-axis degree are known. The onset of stable and cyclical crack expansion can be verfied by sound emission techniques under corrosive conditions, too. The operational influence of corrosion and radiation can be quantified for specific conditions and states. (DG) [de

    As Taiwan is poor in its energy source as well as Japan is, nuclear power generation is one of important energy sources. Management and disposal (backend) of radioactive wastes accompanied with application to nuclear generation is a large problem for Taiwan which had 36,000 square kilometer of national area (about twice area of Shikoku in Japan) than that for Japan. In Taiwan, as the radioactive waste management policy (RWMP) was established in 1977 to arrange a basic indication of the backend policy, final disposal sites for both low and high level radioactive wastes (spent fuel) are not specified yet. For management of low level radioactive waste, the Taiwan Electric Power Corp. (TPC) reported the most promising area for the final disposal site to Taiwan Committee of Atomic Energy on February, 1998. And, for the high level radioactive waste, TPC intends to specify the final disposal site in 2016, to be under selection of site on aiming at beginning of its operation on 2032. And, on the backend policy in Taiwan its reprocessing option has not been abandoned yet, to remain feasibility of option in disposal of the low level radioactive waste on abroad. Here was introduced on present condition of the backend in Taiwan. (G.K.)

    1978-03-01

    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.

    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.)

    As the methods of uranium enrichment, gas diffusion method and centrifugal separation method in which power consumption is less and the cost is low have been carried out. On the other hand, as the future technology, the research and development of laser isotope separation technology have been carried out. There are the atomic laser separation process in which the laser beam of visible light is irradiated to atomic state uranium and the molecular laser separation process in which far infrared laser beam is irradiated to uranium hexafluoride molecules. The atomic process is divided into three steps, that is, the processes of uranium evaporation, the reaction of uranium with laser beam and the recovery of enriched uranium. The principle of the laser separation is explained. The state of development of laser equipment and separation equipment is reported. The principle and the present state of development of the molecular separation process which consists of the cooling of UF 6 gas, the generation of high power 16 μm laser pulses and the collection of the reaction product are explained. The present state of both processes in foreign countries is reported. (K.I.)

    The earliest known comprehensive karst map of the entire USA was published by Stringfield and LeGrand (1969), based on compilations of William E. Davies of the U.S. Geological Survey (USGS). Various versions of essentially the same map have been published since. The USGS recently published new digital maps and databases depicting the extent of known karst, potential karst, and pseudokarst areas of the United States of America including Puerto Rico and the U.S. Virgin Islands (Weary and Doctor, 2014). These maps are based primarily on the extent of potentially karstic soluble rock types, and rocks with physical properties conducive to the formation of pseudokarst features. These data were compiled and refined from multiple sources at various spatial resolutions, mostly as digital data supplied by state geological surveys. The database includes polygons delineating areas with potential for karst and that are tagged with attributes intended to facilitate classification of karst regions. Approximately 18% of the surface of the fifty United States is underlain by significantly soluble bedrock. In the eastern United States the extent of outcrop of soluble rocks provides a good first-approximation of the distribution of karst and potential karst areas. In the arid western states, the extent of soluble rock outcrop tends to overestimate the extent of regions that might be considered as karst under current climatic conditions, but the new dataset encompasses those regions nonetheless. This database will be revised as needed, and the present map will be updated as new information is incorporated.

    2011-01-01

    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

  10. MR tomography in myocardial ischaemia: present state of the art

    1996-01-01

    Recent developments in MR imaging have opened up new avenues in the investigation of ischaemic heart disease. Conventional unenhanced spin-echo sequences have been used to detect and quantify myocardial infarction. Along with the technical advances aimed at reducing motion artifacts and imaging time, the advent of contrast media for MR imaging has further strengthened its diagnostic capacities. The applications of MR contrast media are increasing, and they are becoming more specific, to enable differentiation of occlusive and reperfused myocardial infarctions and to discriminate between reversible and irreversible myocardial injury. Previous studies have also indicated that dual administration of both relaxivity-based and susceptibility-based contrast media can be used to determine whether viable myocardium is present in the reperfused ischaemic area. Magnetic susceptibility MR contrast media have the potential to demonstrate a region of the ischaemically injured myocardium in which myocardial necrosis is present. A cornestone in the MR assessment of ischaemic heart disease has been achieved with the advent of fast MR imaging techniques. Ultrafast gradient-recalled-echo sequences or echoplanar imaging allow to monitor the first passage of the contrast medium through the heart. With the aid of MR contrast media, these techniques may be useful in estimating regional myocardial perfusion and blood volume. Experimental and clinical perfusion studies indicate that perfusion-sensitive MR imaging, particularly in concert with coronary vasodilators, can detect compromised myocardium. Combining myocardial perfusion imaging with the anatomic and functional information provided by other MR imaging techniques such as cine and velocity-encoded sequences could make MR imaging a comprehensive noninvasive diagnostic tool for the assessment of ischaemic heart disease.

    Storage capacity of spent nuclear fuel storage pools in nuclear power station is reaching to a condition near its limit, and under a condition inevitable on delay of the Pu-thermal utilization plan importance on interim storage of the spent nuclear fuels is further rising. In U.S.A., Germany, and so on, a condition incapable of presenting nuclear energy business itself without its intermediate storage is approaching, so in Japan it will also be a key to smoothly promote the nuclear energy business how the interim storage is used and operated. Under such condition, in Japan storage facilities using a system called by 'metal cask' are established at areas of nuclear power stations to begin their operations. As on the system expensive metal containers are used for storage in themselves, it has a demerit of its high cost. On the other hand, on foreign countries, a storing system called by concrete cask, horizontal silo, or vault is occupying its main stream. Here was introduced present states and future views on vault storage system. (G. K)

    This paper presents results of several imbalanced learning techniques applied to operator functional state assessment where the data is highly imbalanced, i.e., some function states (majority classes) have much more training samples than other states (minority classes). Conventional machine learning techniques usually tend to classify all data samples into majority classes and perform poorly for minority classes. In this study, we implemented five imbalanced learning techniques, including random undersampling, random over-sampling, synthetic minority over-sampling technique (SMOTE), borderline-SMOTE and adaptive synthetic sampling (ADASYN) to solve this problem. Experimental results on a benchmark driving lest dataset show thai accuracies for minority classes could be improved dramatically with a cost of slight performance degradations for majority classes,

    2014-01-01

    Fall prevention is an important and complex multifactorial challenge, since one third of people over 65 years old fall at least once every year. A novel application of Disease State Fingerprint (DSF) algorithm is presented for holistic visualization of fall risk factors and identifying persons with falls history or decreased level of physical functioning based on fall risk assessment data. The algorithm is tested with data from 42 older adults, that went through a comprehensive fall risk assessment. Within the study population the Activities-specific Balance Confidence (ABC) scale score, Berg Balance Scale (BBS) score and the number of drugs in use were the three most relevant variables, that differed between the fallers and non-fallers. This study showed that the DSF visualization is beneficial in inspection of an individual's significant fall risk factors, since people have problems in different areas and one single assessment scale is not enough to expose all the people at risk.

In the last year, the function of research was given to the Agency by the revision of the related law. The full-scale repair works for Mutsu were started in August, 1980, and various equipments and shields in the containment vessel and the upper shields of the containment vessel have been removed. Subsequently, new shields are being installed. According to the report by the committee of nuclear ship research and development, the development of Mutsu, which is valuable as the experimental ship, is continued. Moreover, it is proposed to do the research and development of an improved marine nuclear plant for the purposes of securing the economic efficiency, the proving of the reliability of nuclear merchant ships, and the establishment of safety. As the home port for Mutsu, the new port will be constructed on the open sea side in Aomori Prefecture, and as a candidate, Sekine beach in Mutsu City was named. Till the completion of the new home port, Mutsu will be berthed in Ominato home port. The conditions for entering and berthing in Ominato port will be decided later. (Kako, I.)

    Full Text Available The growing importance of quality of life in diverse domains, such as health, school performance and social participation, has led to the development of new conceptualisations and assessments of the construct. This diversity of perspectives brings about many benefits, but it also creates an obstacle for the formulation of a single unifying definition of the construct and, therefore, an agreed instrument or assessment framework. The aim of this study is to discuss the current methodological challenges in the measurement of quality of life. Firstly, we provide a brief description of the construct as defined in various areas, then we examine the new methodological developments and different applications. We also present an overview of the different possibilities for future developments in defining and measuring quality of life in national and international studies.

    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)

    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.

Initial biopsy revealed granulomas, but Ziehl-Neelsen and Gram stain were negative for TB so antibiotics were prescribed for abscess until culture came positive for tuberculosis. She was started on triple therapy for extrapulmonary tuberculosis, an exceedingly rare presentation that requires high clinical suspicion in the Western world.

    1976-01-01

    A review is given of the state of the theory of a MHD-dynamo, that is, the theory of self-excited magnetic fields in homogeneous moving liquids. A description is given of two basic approaches-the turbulent dynamos of Steinbeck, Krause and Redler and the high-conductivity dynamo of Braginski, and a look is also taken at the relation between these dynamos. Finally a look is taken at the results of recent studies of the total problem of a MHD-dynamo, that is, at the results of recent attempts to solve the electro- and hydrodynamic equations and to obtain self-excited fields. 6 figs., 122 ref.

    Describes the low technological state of Yugoslav coal enterprises,in particular of those that exploit low grade lignite and brown coal with high ash and sulfur content. Unadjusted coal prices (almost the same price level for low and high energy coal) and absence of stringent laws on environmental pollution are regarded as main reasons for the low technological level of coal preparation and beneficiation plants. Modern preparation equipment for coal classification, coal washing, coal drying and briquetting is pointed out. Advanced coal carbonization and gasification should have a wider application in Yugoslavia for reducing environmental pollution and producing clean fuel.

    Process analytical technology (PAT), the regulatory initiative for incorporating quality in pharmaceutical manufacturing, is an area of intense research and interest. If PAT is effectively applied to bioprocesses, this can increase process understanding and control, and mitigate the risk from substandard drug products to both manufacturer and patient. To optimize the benefits of PAT, the entire PAT framework must be considered and each elements of PAT must be carefully selected, including sensor and analytical technology, data analysis techniques, control strategies and algorithms, and process optimization routines. This chapter discusses the current state of PAT in the biopharmaceutical industry, including several case studies demonstrating the degree of maturity of various PAT tools.

  17. State of the art in crystal oscillators - Present and future

    Science.gov (United States)

    Rosati, V. J.; Filler, R. L.; Schodowski, S. S.; Vig, J. R.

    It is pointed out that most military communication, navigation, surveillance and IFF systems which are currently under development require stable oscillators for frequency control and/or timing. Examples of such systems are the Single Channel Ground and Airborne Radio System (SINCGARS), MILSTAR, the Global Positioning System (GPS), the Combat Identification System (CIS), and several radar systems. In 1981, a survey and evaluation program was initiated with the aim to determine the state-of-the-art of both TCXOs (temperature compensated crystal oscillators) and OCXOs (oven controlled crystal oscillators). This program is continuing. The results obtained to date are considered because they can provide useful guidance to system users on the availability of stable oscillators.

    1996-01-01

    Despite the high level of development that probabilistic safety assessment (PSA) methods have reached, a number of issues place constraints on its use in supporting decision making on safety matters. A recent publication of the International Nuclear Safety Advisory Group (INSAG) represents an important step in reaching international consensus on the use of PSA. PSA is ''strongly encouraged'' by INSAG; however, it is noted that ''PSA methodology is not sufficiently mature for its present status to be frozen''. The main aspects of the report are discussed in this paper. The paper next discusses three main categories of PSA application, namely the adequacy of design and procedures, optimization of operational activities and regulatory applications. For each of the applications, the objectives, specific modelling requirements and the prospects for implementation are presented. Consistent with its statutory functions, an important aspect of the work of the IAEA is to reach international consensus on the possibilities of and limitations on the use of PSA methods. Whereas past efforts have been concentrated on promotion and assistance to perform Level 1 PSAs, work is now extending with emphasis on PSA applications, Level 2 and Level 3 analysis, external events and shutdown risks. The main elements of IAEA's PSA Programme are discussed. Finally some challenges related to the use of PSA in the backfitting of nuclear power plants in Eastern Europe and countries of the former USSR are addressed. (orig.)

    Full Text Available The SMS (Short Message Service,which emerged at the beginning of the 90s as a result of the telephone services’ need for diversification, it is now used in the communication campaigns involving customized messaging, but also in general messaging campaigns sent both to the existing clients and to the potential ones. Thus, the SMS became widely used, turning into one of the most popular instruments of Mobile marketing and, soon becoming a separate concept named the SMS Marketing. Although there is the preconception that the mobile marketing and, namely, the SMS marketing is intended to be used primarily by the big corporations, which have the power and also the availability to invest substantial amounts of money in this sort of programs, the present paper intends precisely to debunk these preconceptions and, hence, to present the advantage of such marketing campaigns for the segment consisting of small and middle companies in Romania.

    Treatment of malignant pheochromocytoma and neuroblastoma stage III and IV is unsatisfactory. Locally invasive tumors may be cured by radical extirpation. The role of irradiation and/or chemotherapy in malignant pheochromocytoma is disappointing, in neuroblastoma in many cases debatable. From 1981 to the present we studied more than 250 patients by MIBG scintigraphy. 5 patients with malignant pheochromocytoma, one female patient with an intra-adrenal, probably benign pheochromocytoma and 3 children with neuroblastoma stage IV were treated with I-131-MIBG

    2018-03-01

    In accordance with the Paris Climate Agreement (2015) and the more recent European Union Winter Package of November 2016, the European nations have committed to drastically cut CO2 emissions during the next decades, especially in the power sector. To this end, Spain as well as many other European countries are initiating plans for a large deployment of variable renewable energy sources (VRES), especially motivated by the huge lowering in prices of solar and wind installations. In the first part of this work, a detailed analysis of the current Spanish electricity mix is carried out, especially of the present generation by VRES. To this end, we present hourly and daily fan charts, for the different days of the week as well as months or seasons of the year. These studies show that the current power system is quite varied and presents a large installed capacity in relation to peak demand. Other aspects, that will surely assist the transition to lower emission targets are the following: the recent adjudication of 9000MW of VRES, which will be operational within the next 2-3 years; a large overcapacity of Combined Cycle Gas Turbines (CCGT) plants, which could be used during the transition as backup plants; and the relatively large hydro-pump potential for the storage of possible VRES surpluses. Finally, the possibility of decommissioning several nuclear plants in a few years is also discussed.

    Continuum Damage Mechanics (CDM) has developed since the initial works of Kachanov and Rabotnov. The paper gives a review of its main features, of the present possibilities and of further developments. Several aspects are considered successively: damage definitions and measures, damage growth equations and anisotropy effects, and use of CDM for local approaches of fracture. Various materials, loading conditions and damaging processes are incorporated in the same general framework. Particular attention is given to the possible connections between different definitions of damage, especially between the CDM definition and the information obtained from material science. (orig.)

    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.

    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.

    When being presented to work the operation personnel of the reactor, on Monday January 10, 1983, they noticed that the reactor pool was overflowing of water and the floor of the room was partially flooded. The personnel proceeded to revise the feedwater systems to the pool, the Emergency Cooling System of the core and that of Water of Reinstatement, was found that the passing valve of this last it was lightly open. It was discovered that the water that was flooded in the floor of the room it came from the relief valves of the ports TW-1 and RW-2 and of three glides that were in the Thermal Column area. It was proceeded to lower the one level of water of the pool to their normal position and it was clean the water flooded in the salts. (Author)

    1990-04-01

    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

  9. Skin banking in the United States - past, present and future

    1999-01-01

    Utilizing skin from a suicide victim to treat bums of a young boy struck by lightening, Girdner introduced skin transplantation to the United States in 1881. In the 1930's Padgett introduced the first instrument designed specifically to procure split thickness skin grafts. Padgett's dermatome allowed for reproducible recovery of large areas of fairly uniform skin grafts. This opened the way for the coverage of large wound areas. Fundamental advances in cryopreservation methodologies by the US Navy Tissue Bank in the 1950's paved the way for the preservation and storage of tissues for transplant. In the 60's and 70's the development of dedicated bum units to treat the complexity of bum injuries resulted in an increase demand for allograft skin. To supply local needs, numerous hospital based skin banks began operating throughout the US. By the early 1980's, there were approximately 50 skin banks operating in the U.S. Interestingly, as interest in transplantation of other musculoskeletal tissues increased, many tissue banks chose to focus their attention on the recovery of bone and ligaments and curtailed or eliminated skin recovery programs. Additionally, as the cost of operating tissue banks began to increase, many banks elected to consolidate their services, procure multiple tissues from each donor, and to supply these tissues to centers outside their immediate community The 1990's has revealed the emergence of M ega-Tissue Banks, as smaller, independent banks, faced with ever increasing regulations and pressure for cost containment, merged together or contracted with others for processing or distribution services. Currently, an estimated 120 musculoskeletal tissue banks operate in the U.S. Of these, less than 10 could be considered dedicated skin banks. While the number of skin banks has dwindled, the need to treat large integumental injuries remains. In the US, many biotechnology companies have recognized this need and have focused on the development of allograft

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

    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.

    2003-10-01

    This statement shortly describes the changes in the telecommunication market that have taken place in the last 12 years, during the socio-economical transformation in Poland. It concerns economical, legal and technical problems related to the development of the telecommunications in Poland based on the principles of the market economy. Especially it is related to the commercialization of this sector, what has been a result of the changes of the principal law ruling the national economy including changes ot the telecommunication law. Changes of the law enabled the creation of the commercial company Polish Telecom and opened the way to the privatization of this company. Due to the changed law the way to the step-by-step liberalization and de-monopolization process has been also opened in Poland. It has caused fully digital modernization of telecommunication network, introduction new services such as cellular communications and Internet services, as well as rapid development of the market, what has expressed in multiplication of number of subscribers of stationary telephony, creation of the big cellular market and new increasing Internet market. The statemnet also refers to present difficulties in development of this market and as well as to the prospects for the future developments.

    The businesses of uranium fuel fabrication converting uranium hexafluoride to uranium dioxide powder and forming fuel assemblies are the field of most advanced industrialization among nuclear fuel cycle industries in Japan. At present, five plants of four companies engage in this business, and their yearly sales exceeded 20 billion yen. All companies are planning the augmentation of installation capacity to meet the growth of nuclear power generation. The companies of uranium fuel fabrication make the nuclear fuel of the specifications specified by reactor manufacturers as the subcontractors. In addition to initially loaded fuel, the fuel for replacement is required, therefore the demand of uranium fuel is relatively stable. As for the safety of enriched uranium flowing through the farbicating processes, the prevention of inhaling uranium powder by workers and the precaution against criticality are necessary. Also the safeguard measures are imposed so as not to convert enriched uranium to other purposes than peacefull ones. The strict quality control and many times of inspections are carried out to insure the soundness of nuclear fuel. The growth of the business of uranium fuel fabrication and the regulation of the businesses by laws are described. As the problems for the future, the reduction of fabrication cost, the promotion of research and development and others are pointed out. (Kako, I.)

    Koechlin, L.

    2012-12-01

    The Pic du Midi coronagraph (CLIMSO) is a group of four instruments in parallel, taking images of the whole solar photosphere and low corona. It provides series of 2048*2048 pixels images taken nominally at 1 minute time intervals, all year long, weather permitting. A team of ≃q 60 persons, by groups of 2 or 3 each week, operate the instruments. Their work is programmed in collaboration with Institut de Recherches en astrophysique et planétologie (IRAP) of Observatoire Midi Pyrénées (OMP), and with Programme National Soleil Terre (PNST). The four instruments of CLIMSO (L1, C1, L2 and C2) collect images of the Sun as following: 1) L1 : photosphere in H-α (656.28 nm) ; 2) L2 : photosphere in Ca-II (393.37 nm) ; 3) C1 : prominences in H-α ; 4) C2 : prominences in He-I (1083.0 nm). The data taken are stored in fits format images and mpeg films. They are available publicly on data bases such as BASS 2000 Meudon ({http://bass2000.obspm.fr/home.php?lang=en} and BASS2000 Tarbes ({http://bass2000.bagn.obs-mip.fr/base/sun/index.php}). Several solar studies are carried in relation with these data. In addition to the raw fits images, new images will soon be sent to the data bases: they will be calibrated in solar surface emittance, expressed in W/m^2/nm/steradian. Series of mpeg films for each day are presented in superposed color layers, so as to visualize the multispectral information better. New instrumental developments are planned for the next years and already financed. They will use spectropolarimetry to measure the magnetic field and radial velocities in the photosphere and corona. The data will cover the entire solar disc and have a sample rate of one map per minute.

    Mental illness, including depression, anxiety and bipolar disorder, accounts for a significant proportion of global disability and poses a substantial social, economic and heath burden. Treatment is presently dominated by pharmacotherapy, such as antidepressants, and psychotherapy, such as cognitive behavioural therapy; however, such treatments avert less than half of the disease burden, suggesting that additional strategies are needed to prevent and treat mental disorders. There are now consistent mechanistic, observational and interventional data to suggest diet quality may be a modifiable risk factor for mental illness. This review provides an overview of the nutritional psychiatry field. It includes a discussion of the neurobiological mechanisms likely modulated by diet, the use of dietary and nutraceutical interventions in mental disorders, and recommendations for further research. Potential biological pathways related to mental disorders include inflammation, oxidative stress, the gut microbiome, epigenetic modifications and neuroplasticity. Consistent epidemiological evidence, particularly for depression, suggests an association between measures of diet quality and mental health, across multiple populations and age groups; these do not appear to be explained by other demographic, lifestyle factors or reverse causality. Our recently published intervention trial provides preliminary clinical evidence that dietary interventions in clinically diagnosed populations are feasible and can provide significant clinical benefit. Furthermore, nutraceuticals including n-3 fatty acids, folate, S-adenosylmethionine, N-acetyl cysteine and probiotics, among others, are promising avenues for future research. Continued research is now required to investigate the efficacy of intervention studies in large cohorts and within clinically relevant populations, particularly in patients with schizophrenia, bipolar and anxiety disorders.

  18. Assessment of UF6 Equation of State

    Energy Technology Data Exchange (ETDEWEB)

    Brady, P; Chand, K; Warren, D; Vandersall, J

    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.

    With the slow but constant progress in the coherent control of quantum systems, it is now possible to create large quantum superpositions. There has therefore been an increased interest in quantifying any claims of macroscopicity. We attempt here to motivate three criteria which we believe should...... enter in the assessment of macroscopic quantumness: The number of quantum fluctuation photons, the purity of the states, and the ease with which the branches making up the state can be distinguished. © 2014....

    Full Text Available The aim of the present study was to investigate the effects of video presentations of natural landscapes on European starlings' (Sturnus vulgaris stereotypic behaviours (SBs and other abnormal repetitive behaviours (ARBs and to evaluate the impact of past experience by comparing wild-caught and hand-reared starlings' reactions. Ten wild-caught and five hand-reared starlings were presented 1-hour videos of landscapes twice a day for five successive days, while a control group of eight wild-caught and four hand-reared starlings was presented a grey screen for the same amount of time. The analysis of the starlings' behaviour revealed that the video presentations of landscapes appeared to have a positive but limited and experience-dependent effect on starlings' SBs and other ARBs compared to the controls. Indeed, whereas video presentations seemed to modulate high rates of SBs and ARBs, they did not appear to be enriching enough to prevent the emergence or the development of SBs and ARBs in an impoverished environment. They even appeared to promote a particular type of SB (somersaulting that is thought to be linked to escape motivation. The fact that this effect was observed in hand-reared starlings suggests that videos of landscapes could elicit motivation to escape even in birds that never experienced outdoor life. These results highlight the importance of investigating stereotypic behaviour both quantitatively and qualitatively in order to provide crucial clues on animal welfare.

    Prospective delineation of viable from nonviable myocardium in patients with coronary artery disease in an important factor in deciding whether a patient should be revascularized or treated medically. Two common techniques--single-photon emission computed tomography (SPECT) and positron-emission computed tomography (PET)--are used in nuclear medicine using various radiopharmaceuticals for the detection of myocardial viability in patients. Thallium-201 (201Tl) and technetium-99m (99mTc)-sestamibi are the common radiopharmaceuticals used in different protocols using SPECT, whereas fluoride-18 (18F)-fluorodeoxyglucose (FDG) and rubidium-82 (82Rb) are most widely used in PET. The SPECT protocols involve stress/redistribution, stress/redistribution/reinjection, and rest/redistribution imaging techniques. Many studies have compared the results of 201Tl and (99mTc)-sestamibi SPECT with those of FDG PET; in some studies, concordant results have been found between delayed thallium and FDG results, indicating that 201Tl, although considered a perfusion agent, shows myocardial viability. Discordant results in a number of studies have been found between sestamibi and FDG, suggesting that the efficacy of sestamibi as a viability marker has yet to be established. Radiolabeled fatty acids such as iodine-123 (123I)-para-iodophenylpentadecanoic acid and carbon-11 (11C)-palmitic acid have been used for the assessment of myocardial viability with limited success. 11C-labeled acetate is a good marker of oxidative metabolism in the heart and has been used to predict the reversibility of wall motion abnormalities. (18F)-FDG is considered the marker of choice for myocardial viability, although variable results are obtained under different physiological conditions. Detection of myocardial viability can be greatly improved by developing new equipment and radiopharmaceuticals of better quality.

    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.

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

    Science.gov (United States)

    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. Given the smaller

  11. DETERMINATION OF THE PRESENT VEGETATION STATE OF A WETLAND WITH UAV RGB IMAGERY

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available The compositional and structural characteristics of wetland vegetation play a vital role in the services that a wetland supplies. Apart from being important habitats, wetland vegetation also provide services such as flood attenuation and nutrient retention. South Africa is known to be a water scarce country. The protection and continuous monitoring of wetland ecosystems is therefore important. Factors such as site transformation and disturbance may completely change the vegetation of a wetland and the use of Unmanned Aerial Vehicle (UAV imagery can play a valuable role in high-resolution monitoring and mapping. This study assessed if the use of UAV RGB imagery can enhance the determination of the present vegetation state of a wetland. The WET-Health level two (detailed on-site evaluation methodology was followed for the vegetation assessment, where wetland health is a measure of the deviation of a wetland’s structure and function from its natural reference condition. The mapping of the disturbances classes was then undertaken using ultra-high resolution orthophotos, point clouds and digital surface models (DSM. The WET-Health vegetation module completed with the aid of the UAV products still indicates that the vegetation of the wetland is largely modified (“D” PES Category and that the vegetation of the wetland will further deteriorate (change score. These results are the same as determined in the baseline study. However a higher impact (activities taking place within the wetland score were determined. The assessment of various WET-Health vegetation indicators were significantly enhanced using the UAV imagery and derived products. The UAV products provided an accurate vantage point over the wetland and surroundings, and assisted to easily refine the assessment of the disturbance classes and disturbance units.

    1990-07-01

    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

    Much of what is known about the significance of human papillomavirus (HPV) in oropharyngeal squamous cell carcinoma is derived from single-institution retrospective studies, post hoc analyses of tissue specimens from clinical trials, and tissue bank studies with a small sample size. The objective of this study is to investigate the impact of HPV on the frequency and clinical presentation of oropharyngeal carcinoma in a large, national sample with information from patients who underwent HPV testing. Retrospective, cross-sectional study. We identified a comprehensive national sample of 8,359 patients with oropharyngeal carcinoma and known HPV status diagnosed between 2010 and 2011 within the National Cancer Database. Multivariable logistic regression was used to assess correlates of patient and tumor characteristics on HPV status. Among patients with oropharyngeal carcinoma, the frequency of HPV-related squamous cell carcinoma in the United States was 65.4%. HPV-related oropharyngeal carcinoma was associated with younger age, male sex, and white race (P presentation (P clinical profile, supporting efforts to re-evaluate the staging and treatment paradigm for HPV-associated oropharyngeal cancer. 4.

  15. Examination of cortisol and state anxiety at an academic setting with and without oral presentation.

    Merz, Christian Josef; Wolf, Oliver Tobias

    2015-01-01

    Holding oral presentations in a university course is perceived as stressful and can increase stress hormone concentrations and state anxiety. In such a naturalistic setting, further attention should be paid to the relationship between psychological and hormonal measures of acute stress, as well as women's intake of hormonal contraceptives as a potential moderating variable. In the present study, 76 healthy students gave saliva samples before and after their oral presentations in a university course as well as on a second, control day in the same course without giving an oral presentation. Anticipatory state anxiety was rated on both days. Cortisol concentrations as well as state anxiety were substantially higher on the presentation relative to the control day. During the oral presentation, an increase in cortisol concentrations was observed, whereas a decrease occurred on the control day. Nearly the same picture emerged for both variables when looking at men, women taking hormonal contraceptives and free-cycling women separately. A positive correlation was found between the change in anticipatory state anxiety in the presentation compared to the control day and cortisol concentrations before and after the oral presentation. Concluding, oral presentations constitute a potent stressor and do not seem to be substantially different between men, free-cycling women and women taking hormonal contraceptives. Future studies may want to explore changes associated with specific menstrual cycle phases and with specific hormonal contraceptives.

  18. Distribution, morphological variability, ecology and the present state of Nitella from Lake Ohrid and its surroundings

    Directory of Open Access Journals (Sweden)

    Trajanovska Sonja

    2012-01-01

    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.

  1. Assessment and presentation of uncertainties in probabilistic risk assessment: how should this be done

    International Nuclear Information System (INIS)

    Garlick, A.R.; Holloway, N.J.

    1987-01-01

    Despite continuing improvements in probabilistic risk assessment (PRA) techniques, PRA results, particularly those including degraded core analysis, will have maximum uncertainties of several orders of magnitude. This makes the expression of results, a matter no less important than their estimation. We put forward some ideas on the assessment and expression of highly uncertain quantities, such as probabilities of outcomes of a severe accident. These do not form a consistent set, but rather a number of alternative approaches aimed at stimulating discussion. These include non-probability expressions, such as fuzzy logic or Schafer's support and plausibility which abandon the purely probabilistic expression of risk for a more flexible type of expression, in which other types of measure are possible. The 'risk equivalent plant' concepts represent the opposite approach. Since uncertainty in a risk measure is in itself a form of risk, an attempt is made to define a 'risk equivalent' which is a risk with perfectly defined parameters, regarded (by means of suitable methods of judgement) as 'equally undesirable' with the actual plant. Some guidelines are given on the use of Bayesian methods in data-free or limited data situations. (author)

    1992-07-01

    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.

    Lundgren, Lawrence

    Environmental geology as practiced in the United States confronts issues in three large areas: Threats to human society from geologic phenomena (geologic hazards); impacts of human activities on natural systems (environmental impact), and natural-resource management. This paper illustrates present U.S. practice in environmental geology by sampling the work of 7 of the 50 state geological surveys and of the United States Geological Survey as well. Study of the work of these agencies provides a basis for identifying avenues for the training of those who will deal with environmental issues in the future. This training must deal not only with the subdisciplines of geology but with education to cope with the ethical, interdisciplinary, and public-communication aspects of the work of the environmental geologist.

    Full Text Available The state of sleep is the natural physiological state of a person that is necessary to continue life, therefore this state can be described in a work of art when characterizing the characters, especially when the dream is broken, and also in the event of dreams. Dreams in the artistic text allow the reader to penetrate into the depths of the psychic sphere of the character. In the story by A.P. Chekhov «Drama on Hunting» dreams that contain certain events and represent certain substances are associated with those phenomena that occurred in the life of the main character Zinoviev. At the same time, they describe the unreal substances and events, which, as it becomes clear later, have a prophetic character. The state of sleep, its violation, the idea of what can dream, why this dreaming occur, the characterization of sleep given by another character has to do with the inner psychological state of different characters. Thus, the reader is presented with the sphere of the unconscious, it is possible to determine the significance of this sphere in the life of the characters of the story.

Today these constructions have reached heights of over 150 m and may be built still higher. From the point of view of safety and relibility this is undoubtedly possible. From an economical point of view, new constructional elements will probably have to be introduced into the design. (orig./AK) [de

  20. 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

  1. Gender, Party, and Presentation of Family in the Social Media Profiles of 10 State Legislatures

    Directory of Open Access Journals (Sweden)

    James M. Cook

    2016-04-01

    Full Text Available Recent research has identified neither consistent gendered stereotypes about legislators among constituents, nor a link between legislators’ gender and their electoral success, nor consistent gender coalitions in legislative voting and co-sponsorship. However, it would be premature to declare that gender is irrelevant to legislative politics. This article considers state legislators’ choice to discuss or omit family in their social media profiles and interprets the choice as a gendered presentation of self. The social media platform Twitter is notable for its status as an especially public stage and for the narrow choice that limited profile space imposes. Different strains in gender theory lead to competing predictions: that women will avoid references to family to avoid making gender salient, that women will highlight references to family to avoid backlash for non-normativity, or that differing gender expectations in different political parties lead to different gender effects. Apart from gender, family references may be more or less available to legislators as a function of their own family status and life stage. Analysis of Twitter profiles of state legislators in 10 US states (N = 911 reveals that party and gender effects interact; controlling for family and life stage circumstances, non-Republican women are moderately more likely to mention family than non-Republican men, but Republican women are much less likely to mention family than Republican men. Gender matters in the social media presentation of legislators’ selves, but in a manner strongly conditioned by party expectations.

    2013-01-01

    Competency measurement is central to the optimisation of outcome oriented educational processes in nursing, similar to the concept of evidence based practice. The classification of measurement tools provides the basis for describing the current state of research and development in relation to competence measurement in nursing science, and any gaps are identified. The article concludes with questioning the importance of outcome oriented quality orientation in order to achieve an increase in quality during training. Further methodological developments and qualitative studies are needed to examine the context specific processes of interaction and learning, beyond competence diagnostics. Copyright © 2012.

    2012-01-01

    Full Text Available Assessing a patient's competence to give informed consent in pre-hospital care is difficult. In the presented case an elderly patient attempted suicide by division of a chronically infected and externalised prosthetic arterial graft. He was able to comprehend his situation and understand the consequences of declining treatment. Without prior knowledge of his medical care and psychological state, however, we did not believe we could fully assess the patient's ability to act in his own best interest. After sedation and resuscitation he was transferred to hospital. This case report discusses a unique method of suicide and the challenge of obtaining valid consent in prehospital care.

    Full Text Available The article analyzes the development of EU — Russia energy relations through the lens of the evolution of three parameters: the political agenda (the Energy Dialogue, the institutional structure, and the legal modalities. The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

  5. Present state and future of CFD based on three-dimensional RANS analysis

    International Nuclear Information System (INIS)

    Kim, Kwang Yong

    2004-01-01

    Computational Fluid Dynamics (CFD) based on Navier-Stokes equations has been developed rapidly for several decades with the developments of high speed computers and numerical algorithms, and presently is regarded as an essential analysis tool in the engineering applications containing fluid flow and convective heat transfer. It is known that for turbulent flow the Navier-Stokes equations can be calculated precisely by Direct Numerical Simulation (DNS). However, DNS needs huge computing time even for simple low-Reynolds number flows, and thus is not practical. Large Eddy Simulation (LES) can be an alternative. But, LES also needs considerable computing time for the analysis of engineering flows, and have some problem in the methods. Therefore, the analysis methods using Reynolds-averaged Navier-stokes equations (RANS) and turbulence closure models are still regarded as the major techniques for the analysis of turbulent flows in spite of the inaccuracy of the prediction. In this presentation, the present state and the prospect of CFD based on three-dimensional RANS analysis are introduced for physical models and numerical algorithms with the engineering examples. Especially, for the analysis of two-phase flows in nuclear reactor, the recently developed techniques are also introduced. And, the presentation includes the methods of design optimization using RANS analysis and numerical optimization techniques with variety of the applications

  6. On importance assessment of aging multi-state system

    Science.gov (United States)

    Frenkel, Ilia; Khvatskin, Lev; Lisnianski, Anatoly

    2017-01-01

    Modern high-tech equipment requires precise temperature control and effective cooling below the ambient temperature. Greater cooling efficiencies will allow equipment to be operated for longer periods without overheating, providing a greater return on investment and increased in availability of the equipment. This paper presents application of the Lz-transform method to importance assessment of aging multi-state water-cooling system used in one of Israeli hospitals. The water cooling system consists of 3 principal sub-systems: chillers, heat exchanger and pumps. The performance of the system and the sub-systems is measured by their produced cooling capacity. Heat exchanger is an aging component. Straightforward Markov method applied to solve this problem will require building of a system model with numerous numbers of states and solving a corresponding system of multiple differential equations. Lz-transform method, which is used for calculation of the system elements importance, drastically simplified the solution. Numerical example is presented to illustrate the described approach.

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 SOR-ring was initially designed so as to do steady operation at 300 MeV, but at present, it is used by injecting electrons at 308 MeV, and thereafter, accelerating to 380 MeV. The beam transport system carrying electrons from an electron synchrotron as the injector to the SOR-ring and the arrangement of the SOR-ring proper are shown. The action of the electron synchrotron and the SOR-ring is outlined. There are eight deflecting electromagnets and four sets of quadrupole electromagnets in the SOR-ring. The length of the straight parts is 1.3 m, and a high frequency accelerating cavity is placed in one of the straight parts, while exhaust pumps are installed in other parts. The arrangement of the electromagnets and the action of various equipments are explained. There are five beam lines in the SOR-ring. The way of using these beam lines is described. The research using the SOR-ring is classified into the research on the state of electrons in solids, the research on the state of electrons by optical reaction, absorption and light emission, the effect of vacuum ultraviolet irradiation to living things, and the research on beam dynamics in the ring. The mode of operation is explained. (Kako, I.)

  14. The past, present, and future of manatees in the southeastern United States: realities, misunderstandings and enigmas

    Science.gov (United States)

    O'Shea, T.J.

    1988-01-01

    A review of the historical and recent (1970s-1980s) literature on the distribution, abundance, and mortality of West Indian manatees (Trichechus manatus) in the southern United States is presented. Recent unpublished data on mortality, Florida boat registrations, size of certain manatee wintering populations, and records outside of Florida are also given. Manatees never regularly occurred outside of Florida, except during the summer in Georgia. Current distribution is also limited largely to Florida and coastal Georgia in summer, with extralimital records in other southeastern states. In winter the range contracts and is centered around warm water sources in Florida. The historical record on past abundance is inconclusive, but does not provide any compelling evidence to claim that manatees ever nearly became extinct. There are no satisfactory means to estimate manatee population size. However, within Florida, manatees have become more widespread and possibly more abundant during the past 30 years due to protection, greater availability of warm water in winter, and in some areas, increased exotic vegetation. Deliberate killing for food was long a historical pressure on manatee populations in Florida, but is not almost non-existent. Nevertheless, recent increasing trends in accidental mortality caused by boats, coupled with an understanding of manatee population dynamics, suggests that the future for manatees is not secure. Ample justification exists for continued manatee conservation efforts.

  15. 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.

    In recent years, built-operate-transfer (BOT) projects have profoundly been accepted under project financing for infrastructure developments in many countries. It requires high financing and involves complex mutual risk. The assessment of the risks is vital to avert huge financial loss. Net present value is widely applied to BOT project where the uncertainties in cash flows are deemed to be deterministic values. This study proposed a fuzzy net present value model taking consideration the assessment of risks from the BOT project. The proposed model is adopted to provide more flexible net present valuation of the project. It is shown and proven that the improved fuzzy cash flow model will provide a valuation that is closed to the real value of the project.

    2006-10-15

    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

  2. Environmental impact assessment in the Fijian state sector

    International Nuclear Information System (INIS)

    2003-01-01

    For over 20 years, the South Pacific state of Fiji has required developers to conduct more than 70 environmental impact assessments (EIA), without specifying the environmental quality or impacts it considers (in)appropriate. 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. Unless these factors change, the comprehensive EIA system proposed in Sustainable Development legislation will not prevent environmental degradation

    State-of-the-art magnetic resonance imaging (MRI) generates high-resolution images of the cardiovascular system. Conventional MRI techniques provide images in six to ten minutes per tomographic slice. New strategies have substantially improved the speed of imaging. The technology is relatively expensive, and its cost-effectiveness remains to be defined in relation to other effective, less expensive, and noninvasive technologies, such as echocardiography and nuclear medicine. The ultimate role of MRI will depend on several factors, including the development of specific applications such as (1) noninvasive angiography, especially of the coronary arteries;(2) noninvasive, high-resolution assessment of regional myocardial blood flow distribution (e.g., using paramagnetic contrast agents); (3) characterization of myocardial diseases using proton-relaxation property changes; and (4) evaluation of in vivo myocardial biochemistry. The three-dimensional imaging capability and the ability to image cardiovascular structures without contrast material give MRI a potential advantage over existing noninvasive diagnostic imaging techniques. This report analyzes current applications of MRI to the cardiovascular system and speculates on their future

    Favez, Nicolas; Frascarolo, France; Grimard, Nathalie

    2016-05-01

    The aim of this article is to present a situation of observation designed for the assessment of family interactions: The PicNic Game (PNG). In this situation, families are invited to play at having a picnic together. This can be done with any number of children, aged from a few weeks to adolescence. A companion assessment tool, the Revised-Picnic Assessment Scale (Re-PAS), allows evaluation of interactions in the family on several dimensions. This article presents the PNG and a preliminary study of the validation of the Re-PAS dimensions in a sample of families (N = 67) with 18-month-old infants and their siblings. The PNG was well-received by the families. Construct validity of the Re-PAS was tested, first against self-reported data by mothers and fathers regarding marital satisfaction, coparenting behavior, and division of household tasks, and then against observed maternal and paternal sensitivity and controlling behaviors assessed during free-play. Results show satisfactory preliminary reliability and validity. Two contrasting cases are presented to illustrate the different interactions highlighted in the PNG. This situation is useful for researchers and clinicians, particularly as a basis for video-feedback work with the family. © 2016 Michigan Association for Infant Mental Health.

    1982-01-01

    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.

    In the maintenance works in nuclear power facilities such as checkup, inspection and repair, for the main purpose of radiation protection, remote operation technology was introduced since relatively early stage, and at present, the robots that carry out the inspection works for confirming the soundness of main equipment have been developed and put to practical use. At the time of introducing these technologies, in addition to the research and development of robots proper, the coordination with the design of plant machinery and equipment facilities as the premise of introducing robots is an important requirement. In this report, the present state of the development of remote inspection technology for fast breeder reactors is introduced, and the matters to which attention is paid in the plant design for introducing robots are explained. First, fast breeder reactors are described. The needs of robotizing and adopting remote operation in nuclear power facilities are explained, using the examples of the inspection system for a reactor vessel and the inspection system for steam generator heat transfer tubes.

    A variety of sources contribute to nutrients in rivers and nutrients may subsequently take various pathways and undergo different transformation processes. We first review representative types of isotopes and the roles of isotope techniques that have been or could be used for nutrient assessment and management. We then present technical, financial and logistical matters to be considered in selecting appropriate isotope techniques for nutrient assessment and management. Lastly we propose several approaches on the application of isotope techniques to make more effective the studies and management of nutrients in rivers in the near future. (author)

    This paper summarizes developmental activities aiming at improving, the status of the Japan's System of safeguards. The integral tests are described which are now being implemented by the Japanese Government to check the effectiveness of the State's System, which must be maintained by the Government under the Safeguards Agreement between Japan and the IAEA under the Treaty on Non-Proliferation of Nuclear Weapons, ratified by Japan in June 1976. A joint experiment has been now implemented by the Nuclear Safety Bureau and the NMCC for knowing and improving the precision and accuracy of analytical measurements used at the bulk-facilities. JAERI, is conducting various R and D work on its own, and through cooperation with NMCC, NSB etc. The authors describe the results of non-destructive γ-spectrometry for the development of isotopic correlation techniques, as well as for the identification, and also refer briefly to measurement methods using the Fast Critical Assembly in JAERI. Measurement methods used in the Pu-fabrication facility of the PNC, and the problem of spent fuels application of safeguards for the reprocessing plant are discussed. The accounting reports coming from Japanese facilities are processed by the computer at the NMCC, and converted into (a) the State's material balance, and (b) the formats to be sent to IAEA. The authors discuss the experience of such data-processing as well as the developmental works for analysing MUF. As a part of the integral test, the experiences concerning planning and performance of inspection are discussed. The present status and future plans of the system of national analytical laboratories are described

    1984-01-01

    An experimental laboratory study has been conducted to assess the criteria for cathodic protection of a buried pipeline. The specific cathodicprotection potential requirements to prevent pitting and general corrosion of steel were determined in six natural soils with various amounts of moisture and oxygen (aerated or deaerated), and were compared to the criteria values of -0.85 V (Cu/CuSO 4 ), 100 mV polarization, 300 mV voltage shift, and Tafel potential. The effects of temperature 60 0 C (140 0 F) anaerobic bacteria, and steel surface condition (bare or mill scaled) on the specific requirements in selected soils were assessed also. Overall, the research concluded the present criteria were generally valid in concept; however, the critical values for the present criteria could vary with the environment, but with one noted exception. This experimental study concluded that the 100 mV polarization criterion was the most generally valid and applicable criterion

    When children require mental health services, clinicians need to conduct assessments that are developmentally sensitive and that include the child's point of view. Drawing is a popular tool that is commonly used in clinical settings. Research on drawing in experimental settings has confirmed that the opportunity to draw while talking increases the amount of verbal information that children report during an interview. The present research examined whether drawing also facilitates children's self reports during a mental health assessment. A total of 33 5-12-year-old children were asked either to draw and tell about their presenting problem or to tell only. Children who drew and told provided twice as much verbal information as children who told only. Further, interviewers in the draw and tell condition used a greater number of minimal responses than did interviewers in the tell only condition. These data have important implications for clinical practice. © The Author(s) 2013.

    2011-01-01

    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).

    Epidemiological studies have reported that a higher perceived age is associated with poor health and higher mortality. However, the method used for the assessment of perceived age differs between studies with regard to age, gender, the number and occupation of assessors as well as the presentation of participants. It is not known whether the clinical experience of the assessor or photographic presentation have an influence on the assessment of perceived age, which the present study aimed to investigate. In a cross-sectional study of 460 women aged 25-93 years, 10 consultants and 10 residents were asked to estimate the age of each participant using three different photographic presentations: facial photograph, whole-body photograph, and combined facial and whole-body photographs. Data were analyzed by means of summary statistics and linear mixed models. The inter-class correlation coefficient within each assessor group and photographic presentation varied from 0.66 to 0.75. Limits of agreement were in a broad range but were similar in the two assessor groups. The best inter-assessor agreement was obtained from photographs of both the face and the whole body. Intra- and inter-assessor agreements between photographic presentations were similar among both assessor groups. The accuracy in age assessment was significantly influenced by the photographic presentation but not by the clinical experience of the assessor. The difference in the mean perceived age of a participant of average age was estimated as +0.40 years (95% CI: -1.80; 2.59) for consultants versus residents, -2.05 years (95% CI: -2.90; -1.19) for facial photographs versus both facial and whole-body photographs, and -1.44 years (95% CI: -2.30; -0.58) for whole-body photographs versus both facial and whole-body photographs. A regression towards the mean age was seen. The assessment of perceived age was influenced by the photographic presentation but not by the clinical experience of the assessor. © 2015 S

    One poorly understood consequence of climate change is its effects on extreme events such as wildfires. Robust associations between wildfire frequency and climatic variability have been shown to exist, indicating that future climate change may continue to have a significant effect on wildfire activity. The Northeastern United States (NEUS) has seen some of the most infamous and largest historic fires in North America, such as the Miramichi Fire of 1825 and the fires of 1947. Although return intervals for large fires in the NEUS are long (hundreds of years), wildfires have played a critical role in ecosystem development and forest structure in the region. Understanding and predicting fire occurrence and vulnerability in the NEUS, especially in a changing climate, is economically and culturally important yet remains difficult due to human impacts (i.e. fire suppression activities and human disturbance). Thus, an alternative method for investigating fire risk in the NEUS is needed. Here, we present a compilation of meteorological data collected from Automated Surface Observing Systems (ASOS) from the NEUS throughout the 20th century through present day. We use these data to compute fifteen common "fire danger indices" employed in the USA and Canada to investigate changes in the region's fire risk over time, as well as the skill of each of these indices at predicting wildfire activity relative to the historical record of fires in the NEUS. We use dynamically-downscaled regional climate model output for the 21st century to project future wildfire activity based on the fire danger indices capable of capturing historical fire activity in the NEUS. These projections will aid in predicting how fire risk in the NEUS will evolve with anticipated climate change.

  20. U.S. Natural Gas System Methane Emissions: State of Knowledge from LCAs, Inventories, and Atmospheric Measurements (Presentation)

    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.

    The optical elements of femtosecond high peak power lasers have to fulfill more and more strict requirements in order to support pulses with high intensity and broad spectrum. In most cases chirped pulse amplification scheme is used to generate high peak power ultrashort laser pulses, where a very precise control of spectral intensity and spectral phase is required in reaching transform-limited temporal shape at the output. In the case of few cycle regime, the conventional bulk glass, prism-, grating- and their combination based compressors are not sufficient anymore, due to undesirable nonlinear effects in their material and proneness to optical damages. The chirped mirrors are also commonly used to complete the compression after a beam transport system just before the target. Moreover, the manufacturing technology requires quality checks right after production and over the lifetime of the mirror as well, since undesired deposition on the surface can lead alteration from the designed value over a large part of the aperture. For the high harmonic generation, polarization gating technology is used to generate single attosecond pulses [1]. In this case the pulse to be compressed has various polarization state falling to the chirped mirrors. For this reason, it is crucial to measure the dispersion of the mirrors for the different polarization states. In this presentation we demonstrate a simple technique to measure the dispersion of arbitrary mirror at angles of incidence from 0 to 55 degree, even for a 12" optics. A large aperture 4" mirror has been scanned over with micrometer accuracy and the dispersion property through the surface has been investigated with a stable interference fringes in that robust geometry. We used Spectrally Resolved Interferometry, which is based on a Michaelson interferometer and a combined visible and infrared spectrometer. Tungsten halogen lamp with 10 mW coupled optical power was used as a white-light source so with the selected

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

    1981-01-01

    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.

    Full Text Available This paper presents the current state of knowledge concerning the examination of the impact of increased temperatures on changes of geomechanical properties of rocks. Based on historical data, the shape of stress–strain characteristics that illustrate the process of the destruction of rock samples as a result of load impact under uniaxial compression in a testing machine, were discussed. The results from the studies on changes in the basic strength and elasticity parameters of rocks, such as the compressive strength and Young’s modulus were compared. On their basis, it was found that temperature has a significant effect on the change of geomechanical properties of rocks. The nature of these changes also depends on other factors (apart from temperature. They are, among others: the mineral composition of rock, the porosity and density. The research analysis showed that changes in the rock by heating it at various temperatures and then uniaxially loading it in a testing machine, are different for different rock types. Most of the important processes that cause changes in the values of the strength parameters of the examined rocks occured in the temperature range of 400 to 600 °C.

    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)

    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

    This paper presents a French battery designed to assess emotional and sociocognitive abilities in neurological patients in clinical practice. The first part of this battery includes subtests assessing emotions: a recognition task of primary facial emotions, a discrimination task of facial emotions, a task of expressive intensity judgment, a task of gender identification, a recognition task of musical emotions. The second part intends to assess some sociocognitive abilities, that is mainly theory of mind (attribution tasks of mental states to others: false believe tasks of first and second order, faux-pas task) and social norms (moral/conventional distinction task, social situations task) but also abstract language and humour. We present a general description of the battery with special attention to specific methodological constraints for the assessment of neurological patients. After a brief introduction to moral and conventional judgments (definition and current theoretical basis), the French version of the social norm task from RJR Blair (Blair and Cipolotti, 2000) is developed. The relevance of these tasks in frontal variant of frontotemporal dementia (fvFTD is illustrated by the report of the results of a study conducted in 18 patients by the Cambridge group and by the personal study of a patient with early stage of vfFTD. The relevance of the diagnostic of sociocognitive impairment in neurological patients is discussed.

    Past attempts to estimate flood risk across the USA either have incomplete coverage, coarse resolution or use overly simplified models of the flooding process. In this paper, we use a new 30m resolution model of the entire conterminous US (CONUS) with realistic flood physics to produce estimates of flood hazard which match to within 90% accuracy the skill of local models built with detailed data. Socio-economic data of commensurate resolution are combined with these flood depths to estimate current and future flood risk. Future population and land-use projections from the US Environmental Protection Agency (USEPA) are employed to indicate how flood risk might change through the 21st Century, while present-day estimates utilize the Federal Emergency Management Agency (FEMA) National Structure Inventory and a USEPA map of population distribution. Our data show that the total CONUS population currently exposed to serious flooding is 2.6 to 3.1 times higher than previous estimates; with nearly 41 million Americans living within the so-called 1 in 100-year (1% annual probability) floodplain, compared to only 13 million according to FEMA flood maps. Moreover, socio-economic change alone leads to significant future increases in flood exposure and risk, even before climate change impacts are accounted for. The share of the population living on the 1 in 100-year floodplain is projected to increase from 13.3% in the present-day to 15.6 - 15.8% in 2050 and 16.4 - 16.8% in 2100. The area of developed land within this floodplain, currently at 150,000 km2, is likely to increase by 37 - 72% in 2100 based on the scenarios selected. 5.5 trillion worth of assets currently lie on the 1% floodplain; we project that by 2100 this number will exceed 10 trillion. With this detailed spatial information on present-day flood risk, federal and state agencies can take appropriate action to mitigate losses. Use of USEPA population and land-use projections mean that particular attention can be

    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.

    Full Text Available Background and aims: The property loss and physical injuries due to fire events in buildings demonstrate the necessity of implementation of efficient and performance based fire safety measures. Effective and high efficiency protection is possible when design and selection of protection measures are based on risk assessment. This study aims at presenting a software method to make possible selection and design of building fire safety measures based upon quantitative risk assessment and building characteristics. Methods: based on “Fire Risk Assessment Method for Engineer (FRAME” a program in MATLB software was written. The first section of this program, according to the FRAME method and based on the specification of a building, calculates the potential risk and acceptable risk level. In the second section, according to potential risk, acceptable risk level and the fire risk level that user want, program calculate concession of protective factor for that building.Results: The prepared software make it possible to assign the fire safety measure based on quantitative risk level and all building specifications. All calculations were performed with 0.001 of precision and the accuracy of this software was assessed with handmade calculations. During the use of the software if an error occurs in calculations, it can be distinguished in the output. Conclusion: Application of quantitative risk assessment is a suitable tool for increasing of efficiency in designing and execution of fire protection measure in building. With using this software the selected fire safety measure would be more efficient and suitable since the selection of fire safety measures performed on risk assessment and particular specification of a building. Moreover fire risk in the building can be managed easily and carefully.

    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 injuries from 1990 to 2003. Injured tended to be male (73.0%) and had a mean age of 12.1 years. Most injuries were attributed to karate (79.5%). The most common 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.

    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

  6. Penetrating and blunt trauma to the neck: clinical presentation, assessment and emergency management.

    Penetrating and blunt trauma to the neck: clinical presentation, assessment ana emergency management. In Belgium, and even in Western Europe, penetrating and blunt injury to the neck is relatively uncommon in both the civilian and military populations. Pre-hospital and emergency assessment and management will therefore always prove challenging, as individual exposure to this specific type of injury remains low. Historically, the neck has been divided into three anatomical zones with specific landmarks to guide the diagnostic and therapeutic approach to penetrating neck injuries. Most penetrating injuries need to be explored surgically, although with the advent of multi-detector computed tomographic angiography (MDCTA), which yields high diagnostic sensitivity, this inflexible approach has recently changed to a more targeted management, based on clinical, radiographic and, if deemed necessary, endoscopic findings. However, some authors have addressed their concern about this novel, 'no-zone' approach, since the risk of missing less apparent aerodigestive tract injuries may increase. It is recommended, therefore, that all patients with penetrating neck injuries be closely observed, irrespective of the initial findings. The incidence of blunt neck injury is much lower, and this makes risk assessment and management even more difficult in comparison with penetrating injuries. Again, MDCTA is most often the first diagnostic tool if a blunt neck injury is suspected, due to its good sensitivity for blunt cerebrovascular injuries (BCVI) as well as for aerodigestive tract injuries. Specific patterns of injury and unexpected neurological and neuro-radiological findings in trauma patients should always warrant further investigation. Despite ongoing debate, systemic anticoagulation is recommended for most BCVI, sometimes combined with endovascular treatment. Aerodigestive tract injuries may present dramatically, but are often more subtle, making the diagnosis more difficult

    Anecdotal evidence suggests retail E85 prices may track retail gasoline prices rather than wholesale costs. This indicates E85 prices may be higher than they would be if priced on a cost basis hence limiting adoption by some price-sensitive consumers. Using publicly available and proprietary E85 and regular gasoline price data, we examine pricing behavior in the market for E85. Specifically, we assess the extent to which local retail competition in E85 markets decreases E85 retail prices. Results of econometric analysis suggest that higher levels of retail competition (measured in terms of station density) are associated with lower E85 prices at the pump. While more precise causal estimates may be produced from more comprehensive data, this study is the first to our knowledge that estimates the spatial competition dimension of E85 pricing behavior by firms.

    Anastomosis, the connection of two structures, is a critical procedure for reconstructive surgery with over 1 million cases/year for visceral indication alone. However, complication rates such as strictures and leakage affect up to 19% of cases for colorectal anastomoses and up to 30% for visceral transplantation anastomoses. Local ischemia plays a critical role in anastomotic complications, making blood perfusion an important indicator for tissue health and predictor for healing following anastomosis. In this work, we apply a real time multispectral imaging technique to monitor impact on tissue perfusion due to varying interrupted suture spacing and suture tensions. Multispectral tissue images at 470, 540, 560, 580, 670 and 760 nm are analyzed in conjunction with an empirical model based on diffuse reflectance process to quantify the hemoglobin oxygen saturation within the suture site. The investigated tissues for anastomoses include porcine small (jejunum and ileum) and large (transverse colon) intestines. Two experiments using interrupted suturing with suture spacing of 1, 2, and 3 mm and tension levels from 0 N to 2.5 N are conducted. Tissue perfusion at 5, 10, 20 and 30 min after suturing are recorded and compared with the initial normal state. The result indicates the contrast between healthy and ischemic tissue areas and assists the determination of suturing spacing and tension. Therefore, the assessment of tissue perfusion will permit the development and intra-surgical monitoring of an optimal suture protocol during anastomosis with less complications and improved functional outcome.

  13. Comprehensive Care Plan Development Using Resident Assessment Instrument Framework: Past, Present, and Future Practices

    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.

    Full Text Available The field of treatment wetlands (TWs is rapidly expanding and, arguably, is tasked with studying and understanding one of the most complex water treatment systems available. Microbial communities are generally considered to be responsible for the majority of wastewater constituent degradation in TWs. However, they are also known to be spatially heterogeneous, temporally dynamic, as well as structurally and functionally diverse. Presented here is a meta-analysis of all peer reviewed TW journal articles which utilized a microbial community assessment methodology over the period of 1988 to July 2016. A total of 1101 papers were reviewed, 512 from 1988 to 2012, 215 of which included a microbial community assessment aspect and were subsequently classified as representing past research, and 589 from 2013 to July 2016, 196 of which were classified as representing current TW microbial community research. In general, TW microbial community research has increased over time, with a marked surge in the past four years. Microbial community structure is currently the most commonly used methodological type followed by activity, enumeration and function, respectively. Areas of research focus included nitrogen transformations (156, organic degradation (33, and emerging contaminants (32, with general characterization studies also accounting for a significant proportion (243. Microbial communities from a range of TW systems have been investigated over the last four years with meso-scale (10–1000 L being the most commonly studied system size followed by large-scale (>100,000 L, micro-scale (<10 L, and pilot-scale (1000–100,000 L. Free water surface flow (SF, horizontal subsurface flow (HF, and vertical flow (VF systems are being studied in approximately equal proportions with the majority of studies focused on gaining fixed media/biofilm samples for analysis (rather than from the rhizosphere or interstitial water.

    This study sought to determine the anatomic characteristics and clinical presentation associated with a calcified nodule (CN) as assessed by optical coherence tomography. CN is an unusual but demonstrable cause of acute coronary syndromes (ACS). We studied 889 de novo culprit lesions in 889 patients (48% ACS) who underwent optical coherence tomography before intervention. CN was defined as an eruptive accumulation of nodular calcification (small fractured calcifications). Using quantitative coronary angiography, the change in the angle of the lesion between diastole and systole was measured (angiographic Δ angle). CN was seen in 4.2% of all lesions and was located more frequently in the ostial or mid right coronary artery. Hemodialysis (odds ratio: 4.0; 95% confidence interval: 1.1 to 13.4; p = 0.04), in-lesion angiographic Δ angle (odds ratio: 1.09; 95% confidence interval: 1.05 to 1.14; p presentation, there was a smaller minimum lumen area (1.04 mm 2 [first quartile, third quartile: 0.69, 1.26] vs. 1.61 [first quartile, third quartile: 1.03, 2.06] mm 2 ; p = 0.02) accompanied by more thrombus (82.4% vs. 20.0%; p presentation. In lesions with severe calcification (maximum calcium arc >180°), 30% of ACS culprit lesions contained a CN, and the presence of a CN was associated with ACS presentation independent of other vulnerable plaque morphologies. The presence of a CN was associated with severe calcification and larger hinge movement of the coronary artery (especially ostial and mid right coronary artery). One-third of the underlying plaque morphology of severely calcified culprit lesions in patients with ACS was caused by a CN. Copyright © 2017 American College of Cardiology Foundation.

    Saltman, Richard B

    2002-06-01

    The desire of national policymakers to encourage entrepreneurial behavior in the health sector has generated not only a new structure of market-oriented incentives, but also a new regulatory role for the State. To ensure that entrepreneurial behavior will be directed toward achieving planned market objectives, the State must shift modalities from staid bureaucratic models of command-and-control to more sensitive and sophisticated systems of oversight and supervision. Available evidence suggests that this structural transformation is currently occurring in several Northern European countries. Successful implementation of that shift will require a new, intensive, and expensive strategy for human resources development, raising questions about the financial feasibility of this incentives-plus-regulation model for less-well-off CEE/CIS and developing countries.

    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.

    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

    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

    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

    Noroviruses are the leading cause of foodborne disease in the United States. Foodborne transmission of norovirus is often associated with contamination of food during preparation by an infected food worker. The U.S. Food and Drug Administration's Food Code provides model food safety regulations for preventing transmission of foodborne disease in restaurants; however, adoption of specific provisions is at the discretion of state and local governments. We analyzed the food service regulations of all 50 states and the District of Columbia (i.e., 51 states) to describe differences in adoption of norovirus-related Food Code provisions into state food service regulations. We then assessed potential correlations between adoption of these regulations and characteristics of foodborne norovirus outbreaks reported to the National Outbreak Reporting System from 2009 through 2014. Of the 51 states assessed, all (100%) required food workers to wash their hands, and 39 (76%) prohibited bare-hand contact with ready-to-eat food. Thirty states (59%) required exclusion of staff with vomiting and diarrhea until 24 h after cessation of symptoms. Provisions requiring a certified food protection manager (CFPM) and a response plan for contamination events (i.e., vomiting) were least commonly adopted; 26 states (51%) required a CFPM, and 8 (16%) required a response plan. Although not statistically significant, states that adopted the provisions prohibiting bare-hand contact (0.45 versus 0.74, P =0.07), requiring a CFPM (0.38 versus 0.75, P =0.09), and excluding ill staff for ≥24 h after symptom resolution (0.44 versus 0.73, P =0.24) each reported fewer foodborne norovirus outbreaks per million person-years than did those states without these provisions. Adoption and compliance with federal recommended food service regulations may decrease the incidence of foodborne norovirus outbreaks.

  9. Positive animal welfare states and reference standards for welfare assessment.

    Science.gov (United States)

    Mellor, D J

    2015-01-01

    Developments in affective neuroscience and behavioural science during the last 10-15 years have together made it increasingly apparent that sentient animals are potentially much more sensitive to their environmental and social circumstances than was previously thought to be the case. It therefore seems likely that both the range and magnitude of welfare trade-offs that occur when animals are managed for human purposes have been underestimated even when minimalistic but arguably well-intentioned attempts have been made to maintain high levels of welfare. In light of these neuroscience-supported behaviour-based insights, the present review considers the extent to which the use of currently available reference standards might draw attention to these previously neglected areas of concern. It is concluded that the natural living orientation cannot provide an all-embracing or definitive welfare benchmark because of its primary focus on behavioural freedom. However assessments of this type, supported by neuroscience insights into behavioural motivation, may now carry greater weight when used to identify management practices that should be avoided, discontinued or substantially modified. Using currently accepted baseline standards as welfare reference points may result in small changes being accorded greater significance than would be the case if they were compared with higher standards, and this could slow the progress towards better levels of welfare. On the other hand, using "what animals want" as a reference standard has the appeal of focusing on the specific resources or conditions the animals would choose themselves and can potentially improve their welfare more quickly than the approach of making small increments above baseline standards. It is concluded that the cautious use of these approaches in different combinations could lead to recommendations that would more effectively promote positive welfare states in hitherto neglected areas of concern.

  10. Employing Computer Assisted Assessment (CAA to facilitate formative assessment in the State Secondary School: a case study

    2012-02-01

    Full Text Available Based on theories of assessment as well as on the pedagogical and administrative advantages Computer Assisted Assessment (CAA has to offer in foreign language learning, the study presented in this paper examines how computers can facilitate the formative assessment of EFL learners and enhance their feeling of responsibility towards monitoring their progress. The subjects of the study were twenty five 14-year-old students attending the third class of a State Gymnasium in Greece. The instruments utilized were questionnaires on motivation and learning styles, three quizzes designed with the software Hot Potatoes, a self–assessment questionnaire and an evaluation questionnaire showing the subjects’ attitudes towards the experience of using computers for assessing purposes. After reviewing formative assessment, CAA and how these two can be combined, the paper focuses on the description of the three class quizzes used in the study. Ιnformation from the questionnaires filled in by students combined with the results of the quizzes, shows how computers can be used to provide continuous ongoing measurement of students’ progress needed for formative assessment. The results are also used to show how students and teachers can benefit from formative CAA and the extent to which such kind of assessment could be applicable in the Greek state school reality.

    Cell blocks are an integral part of cytology, but their utility is recognized probably more now than ever before, largely owing to the significant role they play in ancillary testing, particularly molecular diagnostics. Modifications to improve the cell block method initially introduced more than a century ago have been made over the years. Though their value is acknowledged and they are widely used across laboratories, cell block preparations are not standardized and results of ancillary testing performed on them are inconsistent. This article reviews the state of cell blocks-summarizes the more common, currently available and used methods and their corresponding advantages and shortcomings, outlines the role of alternative techniques (eg, smears), and proposes methods to optimize results.

In some states the answer is clear: State policies either allow or prohibit state assessment opt-outs, or…

  5. Birth in the United States: an overview of trends past and present.

    The picture of birth in the United States today is complex and, as the data above indicates, difficult to describe in simplistic terms. Though many women today have come to believe that there are choices surrounding pregnancy and birth, the beliefs and practices of providers, insurers, and hospital administrators play a major role in either influencing those choices or dictating how they will be manifested. On one hand, technological advances have given women greater options with regard to the outcomes of pregnancy and birth. On the other hand, these very same technological advances place limits on the choices available to the individual. For example, increased efficiency in the placement and use of epidural anesthesia has made this a pain-control option for most of the childbearing women in the United States. The use of an epidural, however, puts limits on the choice of an institution at which to give birth and on the movements/activities of the woman during labor. Twentieth-century developments led to the almost complete demise of midwifery practice in the United States, thus taking birth away from the control of the individual woman and her close, matriarchal support system, and placing it in the hands of the patriarchal world of medicine and the institutions (i.e., hospitals) at which this approach to health care is practiced. Most births went from being normal, home-based events to becoming illness-oriented, hospital-based procedures. Just as some steps were being taken in the latter part of the twentieth century to return some of the control of birth back to pregnant women (e.g., childbirth education classes, the modern home-birth movement, increases in the number of midwifery-tended births), technological advances contributed to continued control by physicians and the hospitals of their practice (e.g., fetal monitoring, epidural anesthesia). Advances in technology have made birth possible for many individuals who otherwise would not have had the opportunity

    2015-05-01

    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.

    2017-01-01

    Full Text Available The Magic Garden of Bogosav Živković in the Leskovac village is a 23.32 acres large complex, spontaneously formed in the 1970s. The spatial concept of the artist was to adjust the artistic creativity and presentation to daily household life. In addition to the valuable works of art exhibited in both the open space and interior, the residential and other buildings do not display particular architectural significance; yet, each of these buildings bears impressive marks of the artist in the form of paintings, reliefs, brass eaves or even household items that, when placed in an unusual setting, become exhibits. The aim of the paper is to present the condition of the site, to draw attention to the value of this space and to propose measures for its protection.

    The Preliminary Assessment of Spatial Competition in the Market for E85 presentation and supplementary report from the U.S. Department of Energy’s National Renewable Energy Laboratory examine how the spacing of E85 fueling stations impacts E85 retail pricing. The analysis finds an inverse correlation between station density and E85 prices, with local competition putting downward pressure on E85 prices. A gas station with E85 whose nearest competitor is within a 0.5 mile radius is associated with a lower E85 price per gallon than an otherwise identical station with E85 whose nearest competitor is farther away. The analysis also finds a higher level of correlation between E85 and both E10 and wholesale gasoline prices than with ethanol costs. This indicates that E85 may, in fact, be priced with respect to its substitute fuel, and not based on the cost of its inputs. These findings help identify key trends and barriers in E85 markets and highlight data gaps that, if addressed, could help enable competitive E85 markets. The analysis was released in February 2017 and uses national and Minnesota-specific price data.

  11. A new parameter to simultaneously assess antioxidant activity for multiple phenolic compounds present in food products.

    Yang, Hong; Xue, Xuejia; Li, Huan; Tay-Chan, Su Chin; Ong, Seng Poon; Tian, Edmund Feng

    2017-08-15

    In this work, we established a new methodology to simultaneously assess the relative reaction rates of multiple antioxidant compounds in one experimental set-up. This new methodology hypothesizes that the competition among antioxidant compounds towards limiting amount of free radical (in this article, DPPH) would reflect their relative reaction rates. In contrast with the conventional detection of DPPH decrease at 515nm on a spectrophotometer, depletion of antioxidant compounds treated by a series of DPPH concentrations was monitored instead using liquid chromatography coupled with quadrupole time-of-flight (LC-QTOF). A new parameter, namely relative antioxidant activity (RAA), has been proposed to rank these antioxidants according to their reaction rate constants. We have investigated the applicability of RAA using pre-mixed standard phenolic compounds, and also extended this application to two food products, i.e. red wine and green tea. It has been found that RAA correlates well with the reported k values. This new parameter, RAA, provides a new perspective in evaluating antioxidant compounds present in food and herbal matrices. It not only realistically reflects the antioxidant activity of compounds when co-existing with competitive constituents; and it could also quicken up the discovery process in the search for potent yet rare antioxidants from many herbs of food/medicinal origins.

    This history of the events, forces, and factors that have brought the world to the brink of nuclear holocaust probes two basic questions: what factors perpetuate the nuclear arms race and why is it so difficult to end. Starting with the opening days of World War II, this study traces the escalating arms race up to the present and notes that, while nuclear arsenals continue to grow, nuclear arms treaties are on the verge of collapse.

    Several topics on taeniasis and cysticercosis in Asia and the Pacific are overviewed. In Asia and the Pacific, three human taeniid species have been recognized: Taenia solium, Taenia saginata and Taenia asiatica. The first topic is on evolution of T. solium. Mitochondrial DNA polymorphisms of T. solium worldwide are discussed with emphasis of two specific genotypes: American-African and Asian. The second topic is recent major advances in sero- and molecular-diagnosis of T. solium cysticercosis in humans, pigs and dogs. The third is the present situation of T. solium taeniasis/cysticercosis in Papua (Irian Jaya), Indonesia. The forth is the present situation of T. solium cysticercosis and T. saginata taeniasis in Bali, Indonesia. The fifth is the present situation of T. asiatica taeniasis in Asia and the Pacific and in North Sumatra, Indonesia. The sixth is on the debate of the exact definition of T. asiatica. Because T. asiatica can not be differentiated from T. saginata morphologically, it is time to re-evaluate T. saginata in Asia and the Pacific. New and broad-based surveys across this region are necessary from epidemiological and public health perspectives, based on evidence.

  14. 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)

    Billock, Rachael M; Chounthirath, Thiphalak; Smith, Gary A

    2017-06-01

    This study characterizes the epidemiology of nonfatal pediatric firework-related injuries in the United States among children and adolescents by analyzing data from the National Electronic Injury Surveillance System from 1990 through 2014. During this 25-year period, an estimated 136 991 (95% CI = 113 574-160 408) children firework-related injuries. The annual injury rate decreased significantly by 30.4% during this period. Most of those injured were male (75.7%), mean patient age was 10.6 years, and 7.6% required hospital admission. The hands (30.0%) were the most commonly injured body region, followed by head and neck (22.2%), and eyes (21.5%). Sixty percent of injuries were burns. Injuries were most commonly associated with firecrackers (26.2%), aerial devices (16.3%), and sparklers (14.3%). Consumer fireworks pose a serious injury risk to pediatric users and bystanders, and families should be encouraged to attend public firework displays rather than use consumer fireworks.

  16. New medical schools in the United States: forces of change past and present.

    Science.gov (United States)

    Smith, Lawrence

    2009-01-01

    The new millennium has ushered in a growth phase in the number of American medical schools. Historically the United States has built schools during bursts of activity with relative quiescence in between these periods. We had a twenty-two year period with no growth in medical school size or number. During that time there were significant changes in patient characteristics, student culture, financial reimbursement, quality, and manpower needs that have put stress on medical schools, hospitals, clinical practice and healthcare systems. In addition, there have been remarkable new opportunities in the way we teach, including changes in teaching methodology, educational technology, and a better understanding of how students actually learn. All of these advances have taken place during a period of enormous pressure to change residency programs, reorganize medical and clinical science, and question the very need for traditional departmental structures. It is likely that the new medical schools will emerge looking different from the older schools and they are likely to catalyze a period of curricular change.

  17. Estimate of the Geothermal Energy Resource in the Major Sedimentary Basins in the United States (Presentation)

    Energy Technology Data Exchange (ETDEWEB)

    Esposito, A.; Porro, C.; Augustine, C.; Roberts, B.

    2012-09-01

    Because most sedimentary basins have been explored for oil and gas, well logs, temperatures at depth, and reservoir properties such as depth to basement and formation thickness are well known. The availability of this data reduces exploration risk and allows development of geologic exploration models for each basin. This study estimates the magnitude of recoverable geothermal energy from 15 major known U.S. sedimentary basins and ranks these basins relative to their potential. The total available thermal resource for each basin was estimated using the volumetric heat-in-place method originally proposed by (Muffler, 1979). A qualitative recovery factor was determined for each basin based on data on flow volume, hydrothermal recharge, and vertical and horizontal permeability. Total sedimentary thickness maps, stratigraphic columns, cross sections, and temperature gradient information was gathered for each basin from published articles, USGS reports, and state geological survey reports. When published data were insufficient, thermal gradients and reservoir properties were derived from oil and gas well logs obtained on oil and gas commission databases. Basin stratigraphy, structural history, and groundwater circulation patterns were studied in order to develop a model that estimates resource size, temperature distribution, and a probable quantitative recovery factor.

    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.

    1979-01-01

    The observed seismic amplitudes of HFT (high-frequency teleseismic) events do not vary with distance as expected for surface sources, but are consistent with sources in the upper mantle of the moon. Thus, the upper mantle of the moon is the only zone where tectonic stresses deriving from differential thermal contraction and expansion of the lunar interior are presently high enough to cause moonquakes. The distribution of shallow moonquake epicenters suggests a possible correlation with impact basins, implying a lasting tectonic influence of impact basins long after their formation. The finite depths now assigned to these shallow moonquakes necessitate further revision to the seismic structural model of the lunar interior.

    Mikhailov, A. V.; Depuev, V. H.; Depueva, A. H.

    An analysis of the F2-layer short-term forecast problem has been done. Both objective and methodological problems prevent us from a deliberate F2-layer forecast issuing at present. An empirical approach based on statistical methods may be recommended for practical use. A forecast method based on a new aeronomic index (a proxy) AI has been proposed and tested over selected 64 severe storm events. The method provides an acceptable prediction accuracy both for strongly disturbed and quiet conditions. The problems with the prediction of the F2-layer quiet-time disturbances as well as some other unsolved problems are discussed

    A 4-year-old girl presented with an intrathoracic tumour that was pleural in origin, invading the right lower lobe. The patient underwent urgent right thoracotomy and surgical excision of the tumour and right lower lobectomy as the tumour was invading that lobe. The histological report initially reported it as a rhabdomyosarcoma, embryonal type, but after consultation it was changed to type III pleuropulmonary blastoma. The patient was treated with chemotherapy but succumbed to the disease 12 months after the diagnosis. Relevant literature on pleuropulmonary blastoma is reviewed.

    Youngs, R.R.; Coppersmith, K.J.; Power, M.S.; Swan, F.H. III

    1985-01-01

    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

    2011-12-01

    Full Text Available Abstract Background Technical advances following the Human Genome Project revealed that high-quality and -quantity DNA may be obtained from whole saliva samples. 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

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

    International Nuclear Information System (INIS)

    Lisnianski, Anatoly

    2007-01-01

    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

    2003-01-01

    This report provides an assessment of the state of the biopower industry and the technology for producing electricity and heat from biomass. Biopower (biomass-to-electricity generation), a proven electricity generating option in the United States and with about 11 GW of installed capacity, is the single largest source of non-hydro renewable electricity. This 11 GW of capacity encompasses about 7.5 GW of forest product industry and agricultural industry residues, about 3.0 GW of municipal solid waste-based generating capacity and 0.5 GW of other capacity such as landfill gas based production. The electricity production from biomass is being used and is expected to continue to be used as base load power in the existing electrical distribution system. An overview of sector barriers to biopower technology development is examined in Chapter 2. The discussion begins with an analysis of technology barriers that must be overcome to achieve successful technology pathways leading to the commercialization of biomass conversion and feedstock technologies. Next, an examination of institutional barriers is presented which encompasses the underlying policies, regulations, market development, and education needed to ensure the success of biopower. Chapter 3 summarizes biomass feedstock resources, characteristics, availability, delivered prices, requirements for processing, and the impediments and barriers to procurement. A discussion of lessons learned includes information on the California biomass energy industry, lessons from commercial biopower plants, lessons from selected DOE demonstration projects, and a short summary of the issues considered most critical for commercial success is presented in Chapter 4. A series of case studies, Chapter 5, have been performed on the three conversion routes for Combined Heat and Power (CHP) applications of biomass--direct combustion, gasification, and cofiring. The studies are based on technology characterizations developed by NREL and EPRI

    When the U.S. Congress passed the Federal Water Pollution Control Act in 1972, later amended by the Clean Water Act (CWA) of 1977, it tasked the newly created U.S. Environmental Protection Agency (EPA), in cooperation with the states, with periodically assessing the quality of U.S. waters and reporting on progress toward meeting the goals of the CWA. In subsequent decades, reviews by various governmental and nongovernmental organizations consistently have found available water quality data and reporting to be inadequate to evaluate the nation's progress [Shapiro et al., 2008]. In response to these concerns, in 1989 EPA's Office of Research and Development initiated the Environmental Monitoring and Assessment Program (EMAP) to develop and demonstrate scientific tools to monitor the status of, and trends in, U.S. aquatic resources and environmental stressors affecting them. Recent EPA-led efforts involve monitoring wadeable perennial streams (streams or rivers shallow enough to be wadeable during seasonal low flows), which make up an estimated 90% of the total length of all perennial flowing waters in the United States [EPA, 2006]. Selected results from the first national survey of these streams, the national Wadeable Streams Assessment (WSA) [EPA, 2006; Paulsen et al., 2008], illustrate how such surveys can provide critical information to guide management of this important resource. Nonmonitoring applications of data from the WSA and earlier regional surveys show the wide-ranging applicability of these rich data sets.

    When being presented to work the operation personnel of the reactor, on Monday January 10, 1983, they noticed that the reactor pool was overflowing of water and the floor of the room was partially flooded. The personnel proceeded to revise the feedwater systems to the pool, the Emergency Cooling System of the core and that of Water of Reinstatement, was found that the passing valve of this last it was lightly open. It was discovered that the water that was flooded in the floor of the room it came from the relief valves of the ports TW-1 and RW-2 and of three glides that were in the Thermal Column area. It was proceeded to lower the one level of water of the pool to their normal position and it was clean the water flooded in the salts. (Author)

    The President and CEO of the Murray Energy Corporation presented his observations on and concerns about the coal and energy industries in the USA, as a coal miner and an energy trader. He outlines the coal mining operations of the Murray Energy Corporation. He offers critical comments about, for example, some unscrupulous energy trading activities, the future of Powder River Basin coal (which he believes may be curtailed by the introduction of clean coal technologies), the lack of expertise in coal mining, the need to revise the law concerning coal company bankruptcies, the need for the government to provide a means to secure bonds, the need to liberalize black lung disease benefits, and the factors deterring improvement of the performance of the eastern coal industry. He criticises current policy and puts forward some recommendations.

    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.

    The aim was to make an inventory of the structures and buildings relating to the history of the use of hydropower along the River Kullaa, which runs into the River Kokemaeki, and to determine how they could be conserved and used in future. Their history and the 1990-91 status will serve as starting points for a master scheme, local plans and plans for individual rapids. The publication first gives a general account of the history of the use of hydropower and the development of hydropower plants. Information has been collected on the establishment and development of structures along the River Kullaa. The 1990-91 status has been established on the basis of inventories and measurements made in the field. The master scheme first examines the River Kullaa and its structures as a whole. Along the river there are three areas, whose development is discussed in the local plans. Finally, plans for the individual rapids are presented for three sites. (author)

  17. Present state of the safety concept of natural-draught cooling towers

    1977-01-01

    Safety and reliability of a building depend on the mechanical model chosen, on the shape deviations of the structure, as well as on the distribution functions and fractile values of the main influences and strength properties of the materials. For the shell, the supports, and the foundation of a natural-draught cooling tower, the wind plays a special, safety-reducing role due to the fact that its upper limit remains unknown. This role is still enhanced by the dead weight of the concrete which partially exceeds the tensile load. This requires a dimensioning concept with partial safety coefficients which is established in the present paper. So far, it has been successfully used in the construction of more than 50 cooling towers. (orig.) [de

    To describe epidemiologic features of sports-related genitourinary (GU) injuries and determine patient cohorts and particular sporting activities associated with increased GU injury risk. The National Electronic Injury Surveillance System, a data set validated to provide a probability sample of injury-related US emergency department (ED) presentations, was analyzed to characterize GU injuries between 2002 and 2010. A total of 13,851 observations were analyzed to derive national estimates. Between 2002 and 2010, an estimated 137,525 individuals (95% confidence interval, 104,490-170,620) presented to US EDs with GU injuries sustained during sporting activities. Nearly three-quarters of injuries occurred in the pediatric population. The most common product involved was a bicycle, representing approximately one-third of injuries in both adult and pediatric populations. Injuries related to team sports such as football, baseball or softball, basketball, and soccer were also common, particularly among boys where they represented a combined third of all injuries. Eighty-nine percent of all patients were evaluated and treated in the ED without inpatient admission. The large majority of injuries involved the external genitalia (60%), and significant injuries of paired GU organs (kidneys and testicles) requiring inpatient admission were rare (8.5%). Sports-related GU injuries are most commonly sustained during the use of a bicycle. However, there are other associated activities with identifiable high-risk cohorts, products, and situations. Consumers, practitioners, and injury-prevention experts can use our epidemiologic data to prioritize and develop strategies aimed at the prevention and limitation of such injuries, particularly when counseling at-risk cohorts, such as those with solitary kidneys or testicles.

    Full Text Available A novel multisensor system with incomplete data is presented for traffic state assessment. The system comprises probe vehicle detection sensors, fixed detection sensors, and traffic state assessment algorithm. First of all, the validity checking of the traffic flow data is taken as preprocessing of this method. And then a new method based on the history data information is proposed to fuse and recover the incomplete data. According to the characteristics of space complementary of data based on the probe vehicle detector and fixed detector, a fusion model of space matching is presented to estimate the mean travel speed of the road. Finally, the traffic flow data include flow, speed and, occupancy rate, which are detected between Beijing Deshengmen bridge and Drum Tower bridge, are fused to assess the traffic state of the road by using the fusion decision model of rough sets and cloud. The accuracy of experiment result can reach more than 98%, and the result is in accordance with the actual road traffic state. This system is effective to assess traffic state, and it is suitable for the urban intelligent transportation system.

  1. Tropospheric Ozone Assessment Report: Present-day ozone distribution and trends relevant to human health

    2018-02-01

    Full Text Available This study quantifies the present-day global and regional distributions (2010–2014 and trends (2000–2014 for five ozone metrics relevant for short-term and long-term human exposure. These metrics, calculated by the Tropospheric Ozone Assessment Report, are: 4th highest daily maximum 8-hour ozone (4MDA8; number of days with MDA8 > 70 ppb (NDGT70, SOMO35 (annual Sum of Ozone Means Over 35 ppb and two seasonally averaged metrics (3MMDA1; AVGMDA8. These metrics were explored at ozone monitoring sites worldwide, which were classified as urban or non-urban based on population and nighttime lights data. Present-day distributions of 4MDA8 and NDGT70, determined predominantly by peak values, are similar with highest levels in western North America, southern Europe and East Asia. For the other three metrics, distributions are similar with North–South gradients more prominent across Europe and Japan. Between 2000 and 2014, significant negative trends in 4MDA8 and NDGT70 occur at most US and some European sites. In contrast, significant positive trends are found at many sites in South Korea and Hong Kong, with mixed trends across Japan. The other three metrics have similar, negative trends for many non-urban North American and some European and Japanese sites, and positive trends across much of East Asia. Globally, metrics at many sites exhibit non-significant trends. At 59% of all sites there is a common direction and significance in the trend across all five metrics, whilst 4MDA8 and NDGT70 have a common trend at ~80% of all sites. Sensitivity analysis shows AVGMDA8 trends differ with averaging period (warm season or annual. Trends are unchanged at many sites when a 1995–2014 period is used; although fewer sites exhibit non-significant trends. Over the longer period 1970–2014, most Japanese sites exhibit positive 4MDA8/SOMO35 trends. Insufficient data exist to characterize ozone trends for the rest of Asia and other world regions.

    In the present study, a risk assessment of plant food supplements (PFS), traditional Chinese medicines (TCM) and herbal teas containing alkenylbenzenes was performed using the Margin of Exposure (MOE) approach. The levels of alkenylbenzenes in botanical preparations collected on the Chinese market were quantified and the combined estimated daily intake (EDI) was determined using dose additivity. The combined EDI values obtained assuming equal potency of all alkenylbenzenes detected in the PFS, TCM and herbal teas were 0.3 to 14.3, 0.05 to 539.4 and 0.04 to 42.5 μg/kg bw/day, respectively. Calculating combined EDI values taking into account the toxic equivalency (TEQ) approach, the values for PFS, TCM and herbal teas were 0.3 to 7.7, 0.05 to 278.0 and 0.02 to 16.5 μg estragole equivalents/kg bw/day, respectively. The MOE values resulting from consumption of these PFS, TCM and one cup of herbal tea per day during life-time were generally lower than 10 000, suggesting a potential priority for risk management. For short-term exposure such as two weeks consumption, applying Haber's rule, only one TCM 6 () still had an MOE value below 10 000. It is concluded that selected consumption of Chinese botanical preparations raise a concern because of exposure to alkenylbenzenes, especially when exposure is for longer periods of time.

    Unacceptably large percentage (20-40%) of breast cancer lumpectomy patients are required to undergo multiple surgeries when positive margins are found upon post-operative histologic assessment. If the margin status can be determined during surgery, surgeon can resect additional tissues to achieve tumor-free margin, which will reduce the need for additional surgeries. Spectrally encoded confocal microscopy (SECM) is a high-speed reflectance confocal microscopy technology that has a potential to image the entire surgical margin within a short procedural time. Previously, SECM was shown to rapidly image a large area (10 mm by 10 mm) of human esophageal tissue within a short procedural time (15 seconds). When used in lumpectomy, SECM will be able to image the entire margin surface of ~30 cm2 in around 7.5 minutes. SECM images will then be used to determine margin status intra-operatively. In this paper, we present results from a study of testing accuracy of SECM for diagnosing malignant breast tissues. We have imaged freshly-excised breast specimens (N=46) with SECM. SECM images clearly visualized histomorphologic features associated with normal/benign and malignant breast tissues in a similar manner to histologic images. Diagnostic accuracy was tested by comparing SECM diagnoses made by three junior pathologists with corresponding histologic diagnoses made by a senior pathologist. SECM sensitivity and specificity were high, 0.91 and 0.93, respectively. Intra-observer agreement and inter-observer agreement were also high, 0.87 and 0.84, respectively. Results from this study showed that SECM has a potential to accurately determine margin status during breast cancer lumpectomy.

    Full Text Available Background: Teenage pregnancies are pregnancies between the age group of 13 and 19 years. Such pregnancies are categorized as high-risk pregnancies worldwide. This makes monitoring during the antenatal, intrapartum, and puerperal periods highly important. Objectives: The aim of this study is to determine the incidence, the mode of presentation, and the materno-fetal outcome in teenage parturients and compare with a control group. Materials and Methods: this prospective case–control study, recruited 63 teenage parturients who presented in labor ward in active phase labour between February 2013 and January 2015. These teenage parturients were matched with a control group in terms of parity and cervical dilatation of not less than or more than 1 cm (+1 cm, but are of age, 22–30 years. Thus, a total number of 126 parturients were studied. The mothers and their babies were followed up until the first 7th day postpartum. Results: In this study, 39 (61.90% and 24 (38.10% were married and unmarried, respectively, among the teenage parturients, whereas 60 (95.24% and 3 (4.7% were married and unmarried among the control group. Majority of the teenage parturients, 57 (90.47% had only primary and secondary education, while 59 (93.47% among the controls had secondary and tertiary levels of education. There were statistically significant differences in the incidences of genital lacerations (9 [14.28%] and 2 [3.18%]: P < 0.05, and the incidences of anemia in pregnancy (9 [14.28%] vs. 2 [3.18%]: P < 0.05 in the teenage and the older parturients. The other outcome measures in the two groups were similar. Conclusion: This study showed that teenage pregnancies with good antenatal, intrapartum, and neonatal care, gives almost the same materno-fetal outcomes as the control group. The determining factors for poor maternal and fetal outcomes are poor socioeconomic status and lack or poor quality of antenatal, intrapartum, and puerperal care.

    A series of attacks on America by terrorism on September 11, 2001 gave us a terrible shock. 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)

    Full Text Available In comparing to both ores and energetical minerals there are occurences of extremly rich non-methallics minerals on the Slovak territory. These minerals represent very large-scale sortiment with a considerable amount of verified reserves. Reserves of magnesite, salt rock, dolomite, limestone, talc, bentonite, clays and another construction minerals present many possibilities of their industrial utilization. A specific case is the mining of dimension stones such as stable ingeneous,sedimentary and metamorphic rocks that are mined in the open-pit blocks. Applicable to the production of both ingeneous stone and gross stone [3].The open-pit mining and dimension stone processing by the both above mentioned stone productions forms are focused mainly to the external and internal building industry. Despite of the fact that the natural reserves of dimension stone are limited at the Slovak territory, being distributed at large numbers of open-pits mines, from the point of view of the next development of the dimension stone industry its technical and economic vitalitycan be expected. The paper deals with both the technological and ecological mining problems of dimension stone and shows the possibilities how to improve both the works productivity and quality of products including the ecological impacts by the dimension stone mining.

    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/cm 2 /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 106 Ru 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) [fr

    2005-01-01

    This presentation is the continuation of the article published in Critical Reviews of Biomedical Engineering, 29(5-6), 2001. That issue contained topics dealing with components and geometry of the human head, classification of head injuries, some early experimental studies, and tolerance considerations. It then dealt with head motion and load characterization, investigations during the period from 1939 to 1966, injury causation and early modeling efforts, the 1966 Head Injury Conference and its sequels, mechanical properties of solid tissues, fluid characterization, and early investigation of the mechanical properties of cranial materials. It continued with a description of the systematic investigations of solid cranial components and structural properties since 1966, fetal cranial properties, analytical head modeling, and numerical solutions of head injury. The paper concluded with experimental dynamic loading of human living and cadaver heads, dynamic loading of surrogate heads, and head injury mechanics. This portion of the paper describes physical head injury experimentation involving animals, primarily primates, human cadavers, volunteers, and inanimate physical models. In order to address the entire domain of head injury biomechanics in the two-part survey, it was intended that this information be supplemented by discussions of head injury tolerance and criteria, automotive and sports safety considerations, and the design of protective equipment, but Professor Goldsmith passed away before these sections could be completed. It is nevertheless anticipated that this attenuated installment will provide, in conjunction with the first part of the survey, a valuable resource for students and practitioners of head injury biomechanics.

    Demidov, V.P.; Bityutskij, P.G.; Sorokina, N.A.; Kozhanov, L.G. (Akademiya Meditsinskikh Nauk SSSR, Moscow. Inst. Onkologii)

    A study was made of an X-ray picture of the larynx and the state of the pharyngoesophageal anastomosis after salvage operations in 72 patients. Horizontal resection was performed in 42 patients, frontal-lateral in 27 and reconstructive laryngectomy in 3. An analysis of clinicoroentgenological changes showed that their nature depended on the type of resection and the area of resected anatomical structures and elements in the larynx as well as on concomitant manifestations of tumor recurrence or inflammatory disorders. Accurate data on resection type and the area of resectable laryngeal structures are indispensable in assessing X-ray changes.

    Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for "Weightlifting." Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as "accidental" if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4,111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2,565) showed that the oldest categories (19-22 and 23-30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to "dropping" and "pinching" in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines.

    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.

    The objective of the research is to analyze the legal regulation in the transplantology field at the present stage in Ukraine. To address identified challenges, the author investigates the foreign countries experience and suggests ways of improving certain mechanism for legal regulation in the field of organ transplantation and anatomical materials. The empiric material of the study included a wide range of legal instruments regulating this sphere of legal relationships, information regarding the problems of their application, statistics, expert analysis of Ukrainian and foreign researchers. Methodological mechanism of current research includes such methods: systematic, logical and formal, structural-functional, comparative. The research found that the most world's successful model for the organization of transplantation is in Spain. Additionally, the criteria for the reception of such a model are singled out as well as certain aspects of their application in Ukraine are analyzed. Particularly, the most important criteria are: universal and general territorial proliferation of national health systems; relevant economic resources (special attention is paid to the fact that transplantation is not a medicine of luxury, and an adequate compensation to hospitals for transplantation operations should serve as a main economic aspect); an adequate and necessary number of doctors and nurses; the availability of advanced technical options for medical mechanical ventilation (air conditioning of dead bodies). The research led to the following overall findings. Due to the rapid development of medical and biological sciences, there is an urgent need on further investigation of legal, moral and ethical, general medical aspects of transplantation with subsequent proposals for improving legislation in the field of human organs transplantation and other anatomical materials. At the same time, development of appropriate legislation by complex groups of cross-disciplinary specialists

    The Institute for Nuclear Research and Nuclear Energy is the biggest one within Bulgarian Academy of Sciences and it is a leading complex center for research and application of the nuclear physics in Bulgaria. The year 2003 was the first for the functioning of the new organization structure of INRNE consisting of 26 laboratories and 4 scientific experimental bases joined according their thematic in 7 scientific directions governed by the correspondent Expert Councils and Specialised Seminars. The scientific staff of the Institute has been worked on about 104 problems during the 2003 mainly on our traditional scientific areas, in particular, in the field of: theory of the elementary particles, field theory, atomic nuclei and quantum phenomena; experimental physics of the elementary particles, nuclear reactions, structure of atomic nuclei, cosmic rays and gamma-astrophysics at ultra high energies; neutron interactions and cross sections, physics of the fission; reactor physics, nuclear energy and nuclear safety and security ect. Now the results are already present and, as can been seen, almost half of the developments are connected with the problems of scientific support of the national nuclear energy production, radioactive waste, monitoring and management of the environment. With few exceptions, all these tasks are financially supported by national, foreign and international organizations. The fundamental end applied research results for 2003 have been accepted for publication or published in more than 300 articles in journals and proceeding of many international conferences. Large amount of these results has been obtained in close collaboration with international and foreign research centers, universities and institutions. Essential progress was obtained by the modernization of the scientific experimental bases of INRNE. The technical design project for the reconstruction of the old research reactor IRT 2000 in the new IRT 200 was successfully finished. The

    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.

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

    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.

    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

    Full Text Available Introduction: Children may present motor development delays that can influence their learning process, hence the need for specific assessment for the early detection of such delays in an attempt to resolve or mitigate possible future damage. Objective: Profile of motor development in children aged 9-11 years old presenting low academic achievement in the municipal education system of Maceio, Alagoas state. Methodology: An exploratory, descriptive, transversal study which uses the Motor Development Scale (MDS to analyze the main components of performance. Evaluations were carried out with 43 children of both genders. Results: The children assessed presented motor profiles ranging from “normal” to “far below average”, corroborating the findings in the literature. Conclusions: The results obtained are in agreement with the literature, showing a close relation between motor development and low school performance, emphasizing the importance of psychomotor intervention for the maturation of more complex motor patterns.

  7. Present state of reprocessing

    1977-01-01

    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 UO 2 -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.) [de

    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

    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

    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

    2018-07-01

    All-solid-state lithium-ion batteries (ASSBs) are considered as next generation energy storage systems. A model might be very useful, which describes all contributions to the internal cell resistance, enables an optimization of the cell design, and calculates the performance of an open choice of cell architectures. A newly developed one-dimensional model for ASSBs is presented, based on a design concept which employs the use of composite electrodes. The internal cell resistance is calculated by linking two-phase transmission line models representing the composite electrodes with an ohmic resistance representing the solid electrolyte (separator). Thereby, electrical parameters, i.e. ionic and electronic conductivity, electrochemical parameters, i.e. charge-transfer resistance at interfaces and lithium solid-state diffusion, and microstructure parameters, i.e. electrode thickness, particle size, interface area, phase composition and tortuosity, are considered as the most important material and design parameters. Subsequently, discharge curves are simulated, and energy- and power-density characteristics of all-solid-state cell architectures are calculated. These model calculations are discussed and compared with experimental data from literature for a high power LiCoO2-Li10GeP2S12/Li10GeP2S12/Li4Ti5O12-Li10GeP2S12 cell.

  20. Assessment report on uranium in the United States of America

    International Nuclear Information System (INIS)

    1980-10-01

    Assessment of the uranium resources in the United States as of October 1, 1980, indicates a range of reserves, in mean values, from 645 thousand tons of U 3 O 8 (in the $30 per pound of U 3 O 8 cost category) to 1.122 million tons (in the $100 per pound of U 3 O 8 category). Ranges of potential resources are also shown for the same cost categories: from 885 thousand to over 2 million tons of U 3 O 8 in the probable class; 346 thousand to over 1 million tons in the possible class; and 311 thousand to nearly 700 thousand tons in the speculative class. There are an estimated 140 thousand tons of U 3 O 8 that could be recovered as a byproduct of phosphate and copper mining through the year 2009. Production capability studies indicate that the demand could be satisfied from currently estimated resources if there is a transition from current production of lower cost resources to production from the $50 per pound of U 3 O 8 resources by the mid 1990s. If, due to foreign competition or other market forces, production incentives are not maintained, domestic production potential will not be realized, and the United States could become dependent on foreign sources for much of its U 3 O 8

    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

    Embedded combat medical personnel require accurate and timely biometric data to ensure appropriate life saving measures. Injured warfighter's operating in remote environments require both assessment and monitoring often while still engaged with enemy forces. Small wearable devices that can be placed on injured personnel capable of collecting essential biometric data, including the capacity to remotely deliver collected data in real-time, would allow additional medical monitoring and triage that will greatly help the medic in the battlefield. These new capabilities will provide a force multiplier through remote assessment, increased survivability, and in freeing engaged warfighter's from direct monitoring thus improving combat effectiveness and increasing situational awareness. Key questions around what information does the medic require and how effective it can be relayed to support personnel are at their early stages of development. A low power biometric wearable device capable of reliable electrocardiogram (EKG) rhythm, temperature, pulse, and other vital data collection which can provide real-time remote monitoring are in development for the Soldier.

    For the first time, in situ electromagnetic field exposure of the general public to fields from long term evolution (LTE) cellular base stations is assessed. Exposure contributions due to different radiofrequency (RF) sources are compared with LTE exposure at 30 locations in Stockholm, Sweden. Total exposures (0.2-2.6 V/m) satisfy the International Commission on Non-Ionizing Radiation Protection (ICNIRP) reference levels (from 28 V/m for frequency modulation (FM), up to 61 V/m for LTE) at all locations. LTE exposure levels up to 0.8 V/m were measured, and the average contribution of the LTE signal to the total RF exposure equals 4%.

    Conclusion: This study identified 11.4% diabetics among TB patients presenting to a tertiary care facility. Despite the high diabetes incidence in Pakistan, 71% of the diabetics in the group studied did not know their status. Given the negative impact of diabetes on treatment outcomes of TB, it is important that screening for diabetes be included as initial workup for TB patients. Identification and management of diabetes would result in improved outcomes for TB treatment.

    Following normal neuronal activity, there is an increase in cerebral blood flow and cerebral blood volume to provide oxygenated hemoglobin to active neurons. For abnormal activity such as epileptiform discharges, this hemodynamic response may be inadequate to meet the high metabolic demands. To verify this hypothesis, we developed a novel hyperspectral imaging system able to monitor real-time cortical hemodynamic changes during brain surgery. The imaging system is directly integrated into a surgical microscope, using the white-light source for illumination. A snapshot hyperspectral camera is used for detection (4x4 mosaic filter array detecting 16 wavelengths simultaneously). We present calibration experiments where phantoms made of intralipid and food dyes were imaged. Relative concentrations of three dyes were recovered at a video rate of 30 frames per second. We also present hyperspectral recordings during brain surgery of epileptic patients with concurrent electrocorticography recordings. Relative concentration maps of oxygenated and deoxygenated hemoglobin were extracted from the data, allowing real-time studies of hemodynamic changes with a good spatial resolution. Finally, we present preliminary results on phantoms obtained with an integrated spatial frequency domain imaging system to recover tissue optical properties. This additional module, used together with the hyperspectral imaging system, will allow quantification of hemoglobin concentrations maps. Our hyperspectral imaging system offers a new tool to analyze hemodynamic changes, especially in the case of epileptiform discharges. It also offers an opportunity to study brain connectivity by analyzing correlations between hemodynamic responses of different tissue regions.

    In compliance with its mandate to accelerate the development and use of energy technologies in furtherance of the state's economic growth and the best interests of its population, the New York State Energy Research and Development Authority (NYSERDA) initiated, in March 1977, an assessment of energy research and development priorities. This report presents a view of the energy supply-demand future of the state, and the ways in which this future can be affected by external contingencies and concerted policies. That view takes into consideration energy supplies that may be available to the state as well as energy demands as they are affected by demographic and economic changes within the state. Also included are the effects of national energy policies and technological developments as they modify both supplies and demands in New York State. Finally, this report proceeds to identify those general technological areas in which the Authority's program can be of greatest potential benefit to the state's social and economic well being. This effort aims at a cost/benefit analysis determination of RD and D priorities. The preliminary analysis thus far indicates these areas as being of highest priority: energy conservation in buildings (promotion and execution of RD and D) and industry; district heating; fuel cell demonstration;solar heating and cooling (analysis, demonstration, and information dissemination); energy-environment interaction (analysis); energy information services; and, in general, the attraction of Federal RD and D programs to the state.

    The determination of heat requirements in the first developing phases of plants has been expressed as Growing Degree Days (GDD). The current study focuses on three selected study areas in Greece that are characterised by different climatic conditions due to their location and aims to assess the future variation and spatial distribution of Growing Degree Days (GDD) and how these can affect the main cultivations in the study areas. Future temperature data were obtained and analysed by the ENSEMBLES project. The analysis was performed for the future periods 2021-2050 and 2071-2100 with the A1B and B1 scenarios. Spatial distribution was performed using a combination of dynamical and statistical downscaling technique through ArcGIS 10.2.1. The results indicated that for all the future periods and scenarios, the GDD are expected to increase. Furthermore, the increase in the Sperchios River basin will be the highest, followed by the Ardas and the Geropotamos River basins. Moreover, the cultivation period will be shifted from April-October to April-September which will have social, economical and environmental benefits. Additionally, the spatial distribution indicated that in the upcoming years the existing cultivations can find favourable conditions and can be expanded in mountainous areas as well. On the other hand, due to the rough topography that exists in the study areas, the wide expansion of the existing cultivations into higher altitudes is unaffordable. Nevertheless, new more profitable cultivations can be introduced which can find propitious conditions in terms of GDD.

    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 137 Cs in soil samples collected from different locations have been measured using high resolution γ-spectrometry. The average concentration were 19±4 Bg/kg for 238 U, 47±11 Bq/kg for 232 Th, 317±65 Bq/kg for 40 K and 2.26 Bq/kg for 137 Cs 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 238 U, 232 Th, 40 K and 137 Cs 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)

    To examine the number and rates of head injuries occurring in the community as a whole for the team sports of ice hockey, soccer, and football by analyzing data from patients presenting to US emergency departments (EDs) from 1990 to 1999. Retrospective analysis. Data compiled for the US Consumer Product Safety Commission using the National Electronic Injury Surveillance System were used to generate estimates for the total number of head injuries, concussions, internal head injuries, and skull fractures occurring on a national level from the years 1990 to 1999. These data were combined with yearly participation figures to generate rates of injuries presenting to the ED for each sport. There were an estimated 17,008 head injuries from ice hockey, 86,697 from soccer, and 204,802 from football that presented to US EDs from 1990 to 1999. The total number of concussions presenting to EDs in the United States over the same period was estimated to be 4820 from ice hockey, 21,715 from soccer, and 68,861 from football. While the rates of head injuries, concussions, and combined concussions/internal head injuries/skull fractures presenting to EDs per 10,000 players were not always statistically similar for all 3 sports in each year data were available, they were usually comparable. While the total numbers of head injuries, concussions, and combined concussions/skull fractures/internal head injuries presenting to EDs in the United States are different for ice hockey, soccer, and football for the years studied, the yearly rates for these injuries are comparable among all 3 sports.

    Different brain regions exhibit complex information processing even at rest. Therefore, assessing temporal correlations between regions permits task-free visualization of their `resting state connectivity'. Although functional MRI (fMRI) is widely used for mapping resting state connectivity in the human brain, it is not well suited for `microvascular scale' imaging in rodents because of its limited spatial resolution. Moreover, co-registered cerebral blood flow (CBF) and total hemoglobin (HbT) data are often unavailable in conventional fMRI experiments. Therefore, we built a customized system that combines laser speckle contrast imaging (LSCI), intrinsic optical signal (IOS) imaging and fluorescence imaging (FI) to generate multi-contrast functional connectivity maps at a spatial resolution of 10 μm. This system comprised of three illumination sources: a 632 nm HeNe laser (for LSCI), a 570 nm ± 5 nm filtered white light source (for IOS), and a 473 nm blue laser (for FI), as well as a sensitive CCD camera operating at 10 frames per second for image acquisition. The acquired data enabled visualization of changes in resting state neurophysiology at microvascular spatial scales. Moreover, concurrent mapping of CBF and HbT-based temporal correlations enabled in vivo mapping of how resting brain regions were linked in terms of their hemodynamics. Additionally, we complemented this approach by exploiting the transit times of a fluorescent tracer (Dextran-FITC) to distinguish arterial from venous perfusion. Overall, we demonstrated the feasibility of wide area mapping of resting state connectivity at microvascular resolution and created a new toolbox for interrogating neurovascular function.

    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

    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

  8. What is the evidence that poster presentations are effective in promoting knowledge transfer? A state of the art review.

    2013-03-01

    Poster presentations are a common form of presenting health information at conferences and in the community. Anecdotal evidence within the discipline indicates that health information framed in a poster presentation may be an effective method of knowledge transfer. A state of the art review of the literature was performed to determine the effectiveness of poster presentations on knowledge transfer. Electronic searches of various electronic databases were performed for studies published until 2012. Studies were eligible for inclusion if they provided empirical data on the effectiveness of poster presentations on changes in participant knowledge, attitude or behaviour. A total of 51 studies were identified through the database searches, of which 15 met the inclusion criteria. No study evaluated the effectiveness of posters in comparison with other educational interventions. Most studies utilised a before/after methodology, with the common conclusion that posters elicit greatest effectiveness in knowledge transfer when integrated with other educational modalities. The poster presentation is a commonly used format for communicating information within the academic and public health fields. Evidence from well-designed studies comparing posters to other educational modalities is required to establish an evidence base on the effectiveness of utilising posters in achieving knowledge transfer. © 2013 The authors.

    Saiki, Lori S; Cloyes, Kristin G

    2014-01-01

    Female urinary incontinence is a significant health concern that often remains undisclosed to healthcare providers, often because of embarrassment and fear of a negative response. The purpose of this study was to explore communication patterns found in blog text regarding self-presentation by women living with incontinence for clues to facilitate disclosure. This is a descriptive, empirical study of publically archived blog text (years inclusive 2006-2011; N = 16,629 words from 19 bloggers) by women communicating about urinary incontinence, utilizing methods of content analysis. Valence and word concordance analysis showed that words indicative of facilitating social connections were used more often in proximity with close contacts (Z = -2.68, p = .004) and words indicative of blocking social connections were used more often in proximity with community contacts (Z = -2.97, p = .002). Differences between descriptions of facilitative and blocking reactions from healthcare providers were not significant (Z = -0.28, p = .39). Cluster analysis indicated a decreasing level of negatively charged descriptors of incontinence-related communications as the context moved from the hidden self to close contacts and then to the public sphere. Word frequency analysis identified a pattern in the blog text about urinary incontinence of self-presenting as otherwise fit, healthy, and competent. Study results suggest that any report of incontinence concerns, including joking or casual references, should be addressed because women may not disclose the degree to which symptoms affect their psychosocial health. Further research is needed to explore whether providers might facilitate disclosure of urinary incontinence by first acknowledging the woman's strengths, thereby creating a sense of safety and acceptance.

  10. 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

    2001-01-01

    This paper analyzes four generations of Maintenance Resource Management (MRM) programs implemented by aviation maintenance organizations in the United States. Data collected from over ten years of survey research and field observations are used for this analysis; they are presented in a case-study format. The first three generations of MRM programs were episodic efforts to increase safety through teamwork, focus group discussions, and awareness courses, respectively. Now, the fourth generation programs, characterized by a commitment to long-term communication and behavioral changes in maintenance, are set to build on those earlier generations, toward a culture of mutual trust between mechanics, their managers, and regulators.

    Recently, many organizational accidents have occurred in the electric power, railroad, airline, chemical, food and medical industries due to a lack of knowledge and technology indispensable for effective management. This raises the question of how important transfer of technology and knowledge management is in organizations. This paper clarified present state and related subjects of this problem in terms of human and organizational factors and introduced some advanced cases for the solution so as to find a way to practice the situation-dependent combined approach of existing organizational training and latest knowledge science.

    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).

    Full Text Available Aquatic ecosystems are an essential component of the biogeochemical cycle of mercury (Hg, as inorganic Hg can be converted to toxic methylmercury (MeHg in these environments and reemissions of elemental Hg rival anthropogenic Hg releases on a global scale. Quantification of effluent Hg releases to aquatic systems globally has focused on discharges to the global oceans, rather than contributions to freshwater systems that affect local exposures and risks associated with MeHg. Here we produce a first-estimate of sector-specific, spatially resolved global aquatic Hg discharges to freshwater systems. We compare our release estimates to atmospheric sources that have been quantified elsewhere. By analyzing available quantitative and qualitative information, we estimate that present-day global Hg releases to freshwater environments (rivers and lakes associated with anthropogenic activities have a lower bound of ~1000 Mg· a−1. Artisanal and small-scale gold mining (ASGM represents the single largest source, followed by disposal of mercury-containing products and domestic waste water, metal production, and releases from industrial installations such as chlor-alkali plants and oil refineries. In addition to these direct anthropogenic inputs, diffuse inputs from land management activities and remobilization of Hg previously accumulated in terrestrial ecosystems are likely comparable in magnitude. Aquatic discharges of Hg are greatly understudied and further constraining associated data gaps is crucial for reducing the uncertainties in the global biogeochemical Hg budget.

    Traditionally, written examination and clinical practice assessments are the main ways of deeming midwifery students fit and competent for practice. Contemporary academics in an effort to engage the students in the learning process have employed alternative teaching and assessment strategies. Among the alternative strategies are group projects after which members of the group are awarded the same grade, and peer assessment. With the purpose of informing the midwifery curricular, we utilised a qualitative descriptive approach to explore midwifery students' experiences and views on the use of group poster presentation for learning and assessment. The participants consisted of a purposive sample of 14 higher diploma midwifery students who were registered in a third level institution in Ireland. Semi-structured individual interviews were conducted following the completion of the poster presentation assessment. Permission to undertake the study was obtained from the college ethics committee. In this paper, we focus on the participants' views of group marking and peer assessment which are among the key elements that emerged in this study. While awarding a group mark was overall accepted, peer assessment proved a more contentious issue. Most of the participants found it challenging marking their friends. Reactions to group marks were very much influenced by the group dynamics. Copyright © 2012 Elsevier Ltd. All rights reserved.

    We use GCAM-USA to examine the sensitivity of energy demands and resulting pollutant emissions and health impacts to differing population projections. The population projections are based on future fertility, mortality, migration and education assumptions consistent with the five Shared Socioeconomic Pathways (SSPs) (Jones and O'Neill, 2016). By using a state-level integrated assessment model, we capture the energy and emissions implications of population changes. Additionally, we overlay heating degree days and cooling degree days calculated from climate change projections to assess the individual and combined impacts of population shifts and climate change. A unique aspect of this work is the explicit representation of important regulatory drivers, such as the Cross-State Air Pollution Rule and vehicle efficiency standards. Preliminary results indicate there are significant differences across population scenarios in both U.S. national and state-level emissions. In this presentation, we will examine the influence of underlying factors such as climate, population, and technology changes on emissions and environmental impacts at 2050.

    From 2001, developmental contract studies with Ministry of Education, Culture, Sports, Science and Technology for a compact accelerator for heavy ion radiotherapy of cancer started in National Institute of Radiological Sciences (NIRS) with use of fixed field alternating gradient (FFAG) accelerator, which had been developed in High Energy Accelerator Research Organization (KEK). This paper describes the present state of those studies. Described are FFAG accelerator design for repeated acceleration for 200 Hz or more toward the carbon ion at 400 MeV/u with the range of 25 cm in water, FFAG optical systems for these purposes by linear analyses, and the present situation of the design. Technological problems yielded and future study plan are also commented. (N.I.)

  2. The Impact of Pecha Kucha Presentations in the Assessment of a Translation Studies Unit at The University of Western Australia

    Full Text Available Results of a case study on the implementation of Pecha Kucha presentations undertaken at The University of Western Australia in 2015 are presented and discussed here. Pecha Kucha, a fast-paced presentation format consisting of 20 slides set to proceed automatically every 20 seconds, was used in the assessment of the unit “Translation Localisation” for two reasons: it is a time-effective method to assess a large number of students in a short time, and it has the potential to teach students whilst also assessing them, thus killing two birds with one stone. Recent studies show that the Pecha Kucha style can improve presenting skills and English speaking skills in general. This has particular relevance when teaching large numbers of international students, such as in “Translation Localisation”, where 84% of students spoke English as their second language. The paper ultimately shows how the use of Pecha Kucha presentations in the assessment of a unit carries important pedagogical implications for students of English for Academic Purposes.

    The 2009 Toxicology and Risk Assessment Conference (TRAC) session on 'Advances in Exposure and Toxicity Assessment of Particulate Matter' was held in April 2009 in West Chester, OH. The goal of this session was to bring together toxicology, geology and risk assessment experts from the Department of Defense and academia to examine issues in exposure assessment and report on recent epidemiological findings of health effects associated with particulate matter (PM) exposure. Important aspects of PM exposure research are to detect and monitor low levels of PM with various chemical compositions and to assess the health risks associated with these exposures. As part of the overall theme, some presenters discussed collection methods for sand and dust from Iraqi and Afghanistan regions, health issues among deployed personnel, and future directions for risk assessment research among these populations. The remaining speakers focused on the toxicity of ultrafine PM and the characterization of aerosols generated during ballistic impacts of tungsten heavy alloys.

    Full Text Available Currently, the governments of many countries are facing with a lack of funds for financing programs for social protection of population. Among the causes of this problem, we can indicate the high unemployment rate, which, among other things, is due to implementation of labor-saving technologies. The purpose of this work is to study the impact of technological changes on the sustainability of the state social security system in Ukraine. The general approaches to the assessment of the stability of the state social security system are described. The simulation of the effect of economically efficient technological changes on the company’s income and expenses was carried out. Some patterns of such changes are established. The group of productive technological changes types is presented. The model is developed, and an indicator of the impact estimation of efficiently effective technological changes on the stability of the state social security system is proposed. The analysis of the main indicators of the state social security system functioning of Ukraine is carried out. The dynamics of indicators characterizing the labor market of Ukraine is analyzed. The influence of changes in labor productivity on costs and profits by industries of Ukraine is estimated. The evaluation of the impact of economically efficient technological changes in the industries of Ukraine on the stability of its state social security system is carried out. The different state authorities can use the obtained results for developing measures to manage the sustainability of the state social security system.

    The aim of this study was to describe the current state of home visit nursing services in the Korean context and to suggest future policy directions. First, the three home visit nursing services that have developed in Korea are compared using the analytic framework provided by Gilbert and Terrell in 2012. The framework is based on four dimensions of social welfare: users, services, source of funds, and service delivery process. Second, we perform a strength, weakness, opportunity, and threat analysis to suggest comprehensive and constructive home visit nursing service policies for the future. Specifically, we advocate the creation of an organization that steers the central government to operate an integrated management organization to distribute services and reduce redundancy for preventing the waste of both medical and state financial resources. This study also recommends the development of educational programs to improve the quality of services and service evaluation criteria for the objective assessment of those services. These policy guidelines may prove useful both for Korea and for other countries that intend to prepare or revise their home visit nursing service systems. © 2014 Wiley Periodicals, Inc.

  6. Development of a music therapy assessment tool for patients in low awareness states.

    2007-01-01

    People in low awareness states following profound brain injury typically demonstrate subtle changes in functional behaviors which challenge the sensitivity of measurement tools. Failure to identify and measure changes in functioning can lead to misdiagnosis and withdrawal of treatment with this population. Thus, the development of tools which are sensitive to responsiveness is of central concern. As the auditory modality has been found to be particularly sensitive in identifying responses indicating awareness, a convincing case can be made for music therapy as a treatment medium. However, little has been recommended about protocols for intervention or tools for measuring patient responses within the music therapy setting. This paper presents the rationale for an assessment tool specifically designed to measure responses in the music therapy setting with patients who are diagnosed as minimally conscious or in a vegetative state. Developed over fourteen years as part of interdisciplinary assessment and treatment, the music therapy assessment tool for low awareness states (MATLAS) contains fourteen items which rate behavioral responses across a number of domains. The tool can provide important information for interdisciplinary assessment and treatment particularly in the auditory and communication domains. Recommendations are made for testing its reliability and validity through research.

    In the event of a major radiological emergency, the U.S. Federal Radiological Emergency Response Plan authorises the creation of the Federal Radiological Monitoring and Assessment Center (FRMAC). The FRMAC is established to co-ordinate the Federal off-site monitoring and assessment activities, and is comprised of representatives from several Federal agencies and Department of Energy contractors who provide assistance to the state(s) and Lead Federal Agency. The Evaluation and Assessment (E and A) Division of the FRMAC is responsible for receiving, storing, and interpreting environmental surveillance data to estimate the potential health consequences to the population in the vicinity of the accident site. The E and A Division has commissioned the preparation of a methodology and procedures manual which will result in a consistent approach by Division members in carrying out their duties. The first edition of this manual is nearing completion. In this paper, a brief review of the structure of the FRMAC is presented, with emphasis on the E and A Division. The contents of the E and A manual are briefly described, as are future plans for its expansion. (author)

    Wesseloo, Johan

    2018-06-01

    Mining-induced seismic hazard assessment is an important component in the management of safety and financial risk in mines. As the seismic hazard is a response to the mining activity, it is non-stationary and variable both in space and time. This paper presents an approach for implementing a probabilistic seismic hazard assessment to assess the current hazard state of a mine. Each of the components of the probabilistic seismic hazard assessment is considered within the context of hard rock underground mines. The focus of this paper is the assessment of the in-mine hazard distribution and does not consider the hazard to nearby public or structures. A rating system and methodologies to present hazard maps, for the purpose of communicating to different stakeholders in the mine, i.e. mine managers, technical personnel and the work force, are developed. The approach allows one to update the assessment with relative ease and within short time periods as new data become available, enabling the monitoring of the spatial and temporal change in the seismic hazard.

    2017-03-01

    Pesticide risk assessment in the European regulatory framework is mandatory performed for active substances (pesticides) and the plant protection products they are constituents of. The aim is to guarantee that safe use can be achieved for the intended use of the product. This paper provides a feedback on the regulatory environmental risk assessment performed for pesticide registration at the EU and member state levels. The different steps of pesticide registration are addressed considering both exposure and hazard. In this paper, we focus on the environmental fate and behaviour in surface water together with the aquatic ecotoxicity of the substances to illustrate pesticide regulatory risk assessment performed for aquatic organisms. Current methodologies are presented along with highlights on potential improvements. For instance, as regards exposure aspects, moving from field based to landscape risk assessments is promising. Regarding ecotoxicology, ecological models may be valuable tools when applied to chemical risk assessment. In addition, interest and further developments to better take into account mitigation measures in risk assessment and management are also presented.

    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)

    The Alaskan landscape is changing, both in terms of effects of human activities as a consequence of increased population, social and economic development and their effects on the local and broad landscape; and those effects that accompany naturally occurring hazards such as volcanic eruptions, earthquakes, and tsunamis. Some of the most prevalent changes, however, are those resulting from a changing climate, with both near term and potential upcoming effects expected to continue into the future. Alaska's average annual statewide temperatures have increased by nearly 4°F from 1949 to 2005, with significant spatial variability due to the large latitudinal and longitudinal expanse of the State. Increases in mean annual temperature have been greatest in the interior region, and smallest in the State's southwest coastal regions. In general, however, trends point toward increases in both minimum temperatures, and in fewer extreme cold days. Trends in precipitation are somewhat similar to those in temperature, but with more variability. On the whole, Alaska saw a 10-percent increase in precipitation from 1949 to 2005, with the greatest increases recorded in winter. The National Climate Assessment has designated two well-established scenarios developed by the Intergovernmental Panel on Climate Change (Nakicenovic and others, 2001) as a minimum set that technical and author teams considered as context in preparing portions of this assessment. These two scenarios are referred to as the Special Report on Emissions Scenarios A2 and B1 scenarios, which assume either a continuation of recent trends in fossil fuel use (A2) or a vigorous global effort to reduce fossil fuel use (B1). Temperature increases from 4 to 22°F are predicted (to 2070-2099) depending on which emissions scenario (A2 or B1) is used with the least warming in southeast Alaska and the greatest in the northwest. Concomitant with temperature changes, by the end of the 21st century the growing season is expected

    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 period. 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 general reproduction of global TGM concentrations and the overestimation on South Africa indicate that model simulations of TGM are seriously affected by emissions. The comparison to wet deposition indicates that wet deposition patterns

    ? Is it legitimacy that the states are losing, or are we misidentifying the effect? This paper argues that hypocrisy has very little effect on the legitimacy of states given our current understanding of legitimacy in international relations. Instead, it posits that the primary effect of hypocrisy on states......This paper seeks to do is to unpack the relationship between state hypocrisy and its effects through asking several questions: If states potentially lose their legitimacy when they act hypocritically, in what way does this happen? What does it mean in this context for a state to lose its legitimacy...... is not on their legitimacy, but on their trustworthiness – but even here only under very specific theoretical understandings of trust and under certain conditions....

    Refined risk assessments for birds exposed to flowable and granular formulations ofCPY were conducted for a range of current use patterns in the United States. Overall,the collective evidence from the modeling and field study lines of evidence indicate that flowable and granular CPY do not pose significant risks to the bird communities foraging in agro-ecosystems in the United States. The available information indicates that avian incidents resulting from the legal, registered uses of CPY have been very infrequent since 2002 (see SI Appendix 3). The small number of recent incidents suggests that the current labels for CPY are generally protective of birds.However, incident data are uncertain because of the difficulties associated with finding dead birds in the field and linking any mortality observed to CPY.Plowable CPY is registered for a variety of crops in the United States including alfalfa, brassica vegetables, citrus, corn, cotton, grape, mint, onion, peanut, pome and stone fruits, soybean, sugar beet, sunflower, sweet potato, tree nuts, and wheat under the trade name Lorsban Advanced. The major routes of exposure for birds to flowable CPY were consumption of treated dietary items and drinking water. The Liquid Pesticide Avian Risk Assessment Model (Liquid PARAM) was used to simulate avian ingestion of CPY by these routes of exposure. For acute exposure,Liquid PARAM estimated the maximum retained dose in each of 20 birds on each of1,000 fields that were treated with CPY over the 60-d period following initial application.The model used a 1-h time step. For species lacking acceptable acute oral toxicity data (all focal species except northern bobwhite (C. virginianus) and redwinged blackbird (A. phoeniceus)), a species sensitivity distribution (SSD) approach was used to generate hypothetical dose-response curves assuming high, median and low sensitivity to CPY. For acute risk, risk curves were generated for each use pattern and exposure scenario. The risk

    Neuropsychological testing is considered crucial for differential diagnosis of Alzheimer's disease (AD) and behavioural variant frontotemporal dementia (bvFTD). In-depth neuropsychological assessment revealed specific dysfunctions in the two dementia syndromes. However, a significant overlap of cognitive impairments exists in early disease stages. We questioned whether a standard neuropsychological assessment at initial clinical presentation can delineate patients with AD versus bvFTD. In a retrospective approach, we evaluated and compared how cognitive profiles assessed at initial clinical presentation predicted the diagnosis of later verified AD (n = 43) and bvFTD (n = 26). Additionally, the neuropsychological standard domains memory, language, visuospatial skills, executive functions, praxis and social cognition were subjected to stepwise discriminant analysis to compare their differential contribution to diagnosis. Regardless of diagnosis, a percentage of patients presented with major deterioration in a wide range of cognitive domains when compared with age-matched normative data. Only few significant differences were detected on the group level: Patients with AD were relatively more impaired in the verbal recall, verbal recognition, figure copy, and surprisingly in the executive subdomains, set shifting and processing speed whereas bvFTD was characterised by more deficits in imitation of face postures. A combination of tests for verbal recall, imitation of limb and face postures, and figure copy showed the greatest discriminatory power. Our results imply that the contribution of a standard neuropsychological assessment is limited for differential diagnosis of AD and bvFTD at initial presentation. In contrast to current clinical guidelines, executive functions are neither particularly nor exclusively impaired in patients with bvFTD when assessed within a standard clinical neuropsychological test battery.

    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

    Humans can be exposed to multiple chemicals, but current risk assessment is usually carried out on one chemical at a time. Mycotoxins are commonly found in a variety of foods including those intended to consumption by children namely breakfast cereals. The present study aims to perform, the risk assessment of single and multiple mycotoxins present in breakfast cereals consumed by children (1-3 years old) from Lisbon region, Portugal. Daily exposure of children to ochratoxin A, fumonisins and trichothecenes showed no health risks to the children population considering individual mycotoxins, while exposure to aflatoxin B1 (AFB1) suggested a potential health concern for the high percentiles of intake (P90, P95 and P99). The combined exposure to fumonisins and trichothecenes are not expected to be of health concern. The combined margin of exposure (MoET) for the aflatoxins group could constitute a potential health concern and AFB1 was the main contributor for MoET. Legal limits and control strategies regarding the presence of multiple mycotoxins in foodstuffs is an urgent need. To the best of our knowledge, this is the first time a cumulative risk assessment was performed on multiple mycotoxins present in breakfast cereals consumed by children.

    This article discussed the feasibility of assessing health state by detecting redox state of human body. Firstly, the balance of redox state is the basis of homeostasis, and the balance ability of redox can reflflect health state of human body. Secondly, the redox state of human body is a sensitive index of multiple risk factors of health such as age, external environment and psychological factors. It participates in the occurrence and development of multiple diseases involving metabolic diseases and nervous system diseases, and can serve as a cut-in point for treatment of these diseases. Detecting the redox state of high risk people is signifificantly important for early detection and treatment of disease. The blood plasma and urine could be selected to detect, which is convenient. It is pointed that the indexes not only involve oxidation product and antioxidant enzyme but also redox couple. Chinese medicine constitution reflflects the state of body itself and the ability of adapting to external environment, which is consistent with the connotation of health. It is found that there are nine basic types of constitution in Chinese population, which provides a theoretical basis of health preservation, preventive treatment of disease and personalized treatment. With the combination of redox state detection and the Chinese medicine constitution theory, the heath state can be systemically assessed by conducting large-scale epidemiological survey with classifified detection on redox state of human body.

    Each year the National Low-Level Waste Management Program publishes a state-by-state assessment report. This report provides both national and state-specific disposal data on low-level radioactive waste commercially disposed in the US. Data in this report are categorized according to disposal site, generator category, waste class, volumes, and radionuclide activity. Included in this report are tables showing the distribution of waste by state for 1996 and a comparison of waste volumes and radioactivity by state for 1992 through 1996; also included is a list of all commercial nuclear power reactors in the US as of December 31, 1996. This report distinguishes between low-level radioactive waste shipped directly for disposal by generators and waste that was handled by an intermediary, a reporting change introduced in the 1988 state-by-state report.

    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.

    Full Text Available At present, information technologies (IT are intensively used all over the world in various sectors, and today medical institutions cannot do without them when organizing the process of medical diagnostic. The IT efficiency is determined by the degree of their intellectualization that is by including knowledge bases as their component and by the transition from data processing to the processing of knowledge. The efficiency of making decisions in various areas of activity is determined by the quality and quick delivery of information. Medicine constitutes no exception in this sense. The advanced level of computer technology, applied tools, diagnostics on the basis of automated systems of decision support made it possible to solve the tasks of assessing the state of the object at a qualitatively new level. The subject matter of this study is to ensure the mathematical support of the intelligent information system (IS of assessing the state of the object. The object is understood as a patient who came through a myocardial infarction (MI. The goal of the study is to develop mathematical support of the intelligent IS of assessing and predicting a patient’s condition. To achieve the stated goal, the following tasks were solved: statistically valid and uncorrelated signs were specified; these signs enable distinguishing the group of patients who survived from those who died, “decisive rules” were formulated for predicting the MI clinical outcome. In the process of the study, the mathematical IT of assessing the state of the object was developed. The following result was obtained: the suggested mathematical models for predicting the outcome of myocardial infarction that were developed with the use of the method of discriminant function and took into account human blood values can prevent sudden coronary death and improve the diagnostic efficiency. Conclusions. Mathematical models were developed to predict the state of the object in the event of

    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

    To describe patterns of response to, and assess sexual function and activity elicited by, a self-administered assessment incorporated into a new patient intake form for gynecologic oncology consultation. A cross-sectional study of patients presenting to a single urban academic medical center between January 2010 and September 2012. New patients completed a self-administered intake form, including six brief sexual activity and function items. These items, along with abstracted medical record data, were descriptively analyzed. Logistic regression was used to assess the association between sexual activity and function and disease status, adjusting for age. Median age was 50 years (range 18-91, N=499); more than half had a final diagnosis of cancer. Most patients completed all sex-related items on the intake form; 98% answered at least one. Among patients who were sexually active in the prior 12 months (57% with cancer, 64% with benign disease), 52% indicated on the intake form having, during that period, a sexual problem lasting several months or more. Of these, 15% had physician documentation of the sexual problem. Eighteen women were referred for care. Providers reported no patient complaints about the inclusion of sexual items on the intake form. Nearly all new patients presenting for gynecologic oncology consultation answered self-administered items to assess sexual activity and function. Further study is needed to determine the role of pre-treatment identification of sexual function concerns in improving sexual outcomes associated with cancer diagnosis and treatment.

  1. The 1985 state-by-state assessment of low-level radioactive wastes shipped to commercial disposal sites

    International Nuclear Information System (INIS)

    1986-12-01

    The 1985 report uses the volume of low-level waste reported as received at each commercial disposal site as the national baseline figure. A volume of 75,909 m 3 of radioactive waste containing 748,903 Ci of activity was reported disposed at the commercial sites in 1985. The distribution of these waste volumes by disposal site is presented in Table 1. Table 2 displays typical radionuclides in low-level wastes by sector. Table 3 presents predominant waste forms associated with low-level waste by sector. The total volume and curie values tabulated for each state were obtained directly from the commercial disposal site operators. The total is the sum of the volume and radioactivity reported by Chem Nuclear and US Ecology for each state. Figure 1 displays the disposal capacity remaining at Barnwell, Richland, and Beatty commercial disposal sites as of December 31, 1985. Summary information on commercial nuclear power plant wastes was obtained from semiannual waste and effluent reports submitted to the NRC in accordance with the NRC Regulatory Guide 1.21. Where reported data were not available, data were obtained by communication with the utility. Nonreactor waste volumes are actual amounts recorded as received at the commercial waste repositories in 1985. Waste categories are defined as academic, medical, government, and industrial. New to the 1985 report is Appendix B, 1985 Assessments Listed By Ratified Compacts, as well as the proposed Western and Appalachian compacts. Inclusion of the most accurate information available from all sources has resulted in an improved national waste distribution profile of generator sectors. 11 refs

    1996-01-01

    The State of Idaho and the U.S. DOE have agreed to a one year pilot program to review and analyze DOE's off-site transportation of radioactive materials within Idaho on a shipping-campaign basis. As a part of that effort, the State of Idaho INEL Oversight Program conducts independent transportation risk assessments. These risk assessments are performed for both highway and railroad shipments using the computer codes RADTRAN4 ,and RISKIND 1.11. Some input parameters are customized with. Idaho-specific data, such as population density, accident rates and meteorological data. The dose and risk (to the public, handlers, crew, etc.) are estimated for both incident free and accident scenarios. Source term files are being built for past, current, and future shipments in Idaho. These include transuranic waste. shipments to WIPP, low level waste, mixed waste, spent fuel, and high level waste. Each shipment is analyzed for two types of transportation route segments: county segments and ten-mile segments. Risk estimation for each county segment provides information for allocation of emergency preparedness resources. Risk estimation for each ten-mile segment helps to identify higher risk segments. The dose and risk results are presented in appropriate formats for various audiences. The quantitative risk measures are used to guide appropriate levels of emergency preparedness. GIS tools are being used to graphically present risk information to elected officials and to the general public

  6. Fish stock assessments in the Mediterranean: state of the art

    Directory of Open Access Journals (Sweden)

    Jordi Lleonart

    2003-04-01

    Full Text Available The Mediterranean fisheries are characterised by fragmented fleets, usually composed by relatively small vessels, use of a large number of landing sites, multi-species catches and low CPUEs. Fish are commercialised mainly fresh and the prices are relatively high. These factors make it difficult and expensive to get extensive and reliable data time series and to get biological samples. Most of the fish caught in the Mediterranean are the recruits (0-1 year old of the main target species. Since the recruitment is much more uncertain than the abundance of the adult stages, the assessments are also more uncertain. Furthermore, no TAC or adaptive management is in place, so the administrations do not require monitoring in order to manage the fisheries. The continental shelf is narrow (with some exceptions and there are few stocks shared between two or more countries. Consequently, the international management structures have not been sufficiently enforced, and until recently no regular assessments were made by international working groups. These characteristics have led to a situation in which most of the assessments have been done in the framework of scientific projects, and therefore do not have continuity in time. The results of these assessments have rarely been incorporated in management.

  9. 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.

    2002-01-01

    Decommissioning of nuclear submarines, disposal of highly enriched uranium and defense plutonium as well as processing of high-level wastes are among the most challenging issues of addressing radiation legacy of the 20th century. USA and Russia are the two primary countries that have to deal with the challenge and where most of the fissile materials to be processed are concentrated, nuclear fuel and high-level radioactive waste are stored, and multiple industrial sites and nuclear weapons production facilities are located. In the US, CH2M HILL is managing two of the most important nuclear projects being conducted by the US Department of Energy at the Rocky Flats Environmental Technology Site and at the DOE Hanford Site (177 underground tanks at this site contain 60 percent of the United States' high-level radioactive wastes). Within the framework of the Russian Federal special program 'Radioactive Waste and Spent Nuclear Materials Management, Utilization and Disposal for 1996-2005' works were carried out on the Karachai lake covering with soil, highly active radwaste vitrification and fractionation at the 'Mayak' combine. Currently there is a discussion of launching joint Russian-American initiatives including comparative studies of environmental and public health impacts from high-level waste vitrification and plutonium stabilization processes in Russia and high-level waste removal from tanks in the USA and of continuing comprehensive research with the RADSITE project (USA, European Union, Japan, China and India) using coordinated approaches in 2000-2003. This paper presents comparative studies, technical approaches, and regulatory strategies to address the challenges of managing and closing highly enriched uranium, plutonium, and high level waste sites.

    Myer, GD, Quatman, CE, Khoury, J, Wall, EJ, and Hewett, TE. Youth versus adult “weightlifting” injuries presenting to united states emergency rooms: accidental versus nonaccidental injury mechanisms. J Strength Cond Res 23(7): 2054–2060, 2009—Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for “Weightlifting.” Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as “accidental” if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4, 111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2, 565) showed that the oldest categories (19–22 and 23–30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to “dropping” and “pinching” in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially

    2010-12-01

    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 US radon measurement programme began in the late 1950s 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 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 million homes were added since 1990 to the home

    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

    2000-07-01

    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.

    2012-01-01

    This study was conducted to evaluate the biosafety precautions that applied by diagnostic laboratories in Khartoum state, 2009. A total number of 190 laboratories were surveyed about their compliance with standard biosafety precautions. These laboratories included 51 (27%) laboratories from government, 75 (39%) from private sectors and 64 (34%) laboratories belong to organization providing health care services. The study found that 32 (16.8%) of laboratories appointed biosafety officers. Only, ten (5.2%) participated in training about response to fire emergency, and 28 (14.7%) reported the laboratory accident occurred during work. 45 (23.7%) laboratories had a written standard operation procedures (SOPs), and 35 (18.4%) had written procedures for the lean-up of spills. Moreover, biosafety cabinet was found in 11 (5.8%) laboratories, autoclave in 28 (14.7%) and incinerator in only two (1.1%) laboratories. Sharp disposable containers were found in 84 (44.2%). Fire alarm system was found in 2 (1.1%) laboratories, fire extinguisher in 39 (20.5%) laboratories, and fire emergency exit found in 14 (7.4%) laboratories. Furthermore, 19 (10%) laboratories had a hepatitis B virus vaccination programme, 5 (6.2%) applied BCG vaccine, and 2 (1.1%0) vaccinated the staff against influenza. The study concluded that the standards biosafety precautions adopted by the diagnostic laboratories in Khartoum state was very low. Further, the laboratory personnel awareness towards biosafety principles implementation was very low too.

    2011-01-01

    The number of state policies aimed at fostering biomass utilization has proliferated in recent years in the United States. Several states aim to increase the use of forest and agriculture biomass through renewable energy production. Several more indirectly encourage utilization by targeting aspects of the supply chain from trees standing in the forest to goods sold. This research classifies 370 state policies from across the United States that provides incentives for forest biomass utilization. We compare those policies by types of incentives relative to the supply chain and geographic clustering. We then develop a framework for policy evaluation building on the supply chain steps, which can be used to assess intended and unintended consequences of policy interactions. These findings may inform policy development and identify synergies at different steps in the supply chain to enhance forest biomass utilization.

    Each year the National Low-Level Waste Management Program publishes a state-by-state assessment report. This report provides both national and state-specific disposal data on low-level radioactive waste commercially disposed in US. Data in this report are categorized according to disposal site, generator category, waste class, volumes, and radionuclide activity. Included are tables showing the distribution of waste by state for 1995 and a comparison of waste volumes and radioactivity by state for 1991 through 1995; also included is a list of all commercial nuclear power reactors in US as of Dec. 31, 1994. This report distinguishes low-level radioactive waste shipped directly for disposal by generators and waste handled by an intermediary.

    Assessment of potential impacts and adaptations to global environmental change evaluate the continuously evolving state of science through the lens of relevance to challenges such as planning long-lived infrastructure and managing risks to property, ecosystems, public health, and other valued assets or objectives. These planning and decision contexts present varied challenges, including: multiple attributes at risk from interacting environmental and socioeconomic trends; uncertainties (scientific and otherwise); partial solutions with indefinite costs and benefits; and tradeoffs across stakeholder groups. Research and evaluation of assessments indicate they convey information that is more usable and relevant to decision makers if they are designed as sustained interactions of pertinent scientific and user communities and result in products beyond written reports. This talk will report on the work of a Federal Advisory Committee for the Sustained National Climate Assessment (SNCA) to develop recommendations to increase the SNCA's relevance and usability. The recommendations build on the conclusions of a 2013 report by the predecessor SNCA advisory committee and suggest next steps for (1) engagement, (2) provision of core scientific products, (3) tailoring of information and tools to provide insights under uncertainty, and (4) evaluation of products and outcomes. The recommended process focuses on providing insights relevant to consideration of risks and solutions. While resulting in a wide range of products and outcomes on an ongoing basis, aggregation and assessment of emerging insights and good practice for supporting decision making under uncertainty would recur over a four-year adaptive management cycle in the context of the preparation of the US national assessment report mandated under the Global Change Research Act.

    Literature from academia, industry, and other Government agencies was surveyed to assess the state of the art in current Integrated Resilient Aircraft Control (IRAC) aircraft technologies. Over 100 papers from 25 conferences from the time period 2004 to 2009 were reviewed. An assessment of the general state of the art in adaptive flight control is summarized first, followed by an assessment of the state of the art as applicable to 13 identified adverse conditions. Specific areas addressed in the general assessment include flight control when compensating for damage or reduced performance, retrofit software upgrades to flight controllers, flight control through engine response, and finally test and validation of new adaptive controllers. The state-of-the-art assessment applicable to the adverse conditions include technologies not specifically related to flight control, but may serve as inputs to a future flight control algorithm. This study illustrates existing gaps and opportunities for additional research by the NASA IRAC Project

    2008-05-01

    This review deals with the current state of knowledge on the use of the benchmark dose (BMD) concept in health risk assessment of chemicals. The BMD method is an alternative to the traditional no-observed-adverse-effect level (NOAEL) and has been presented as a methodological improvement in the field of risk assessment. The BMD method has mostly been employed in the USA but is presently given higher attention also in Europe. The review presents a number of arguments in favor of the BMD, relative to the NOAEL. In addition, it gives a detailed overview of the several procedures that have been suggested and applied for BMD analysis, for quantal as well as continuous data. For quantal data the BMD is generally defined as corresponding to an additional or extra risk of 5% or 10%. For continuous endpoints it is suggested that the BMD is defined as corresponding to a percentage change in response relative to background or relative to the dynamic range of response. Under such definitions, a 5% or 10% change can be considered as default. Besides how to define the BMD and its lower bound, the BMDL, the question of how to select the dose-response model to be used in the BMD and BMDL determination is highlighted. Issues of study design and comparison of dose-response curves and BMDs are also covered. Copyright (c) 2007 John Wiley & Sons, Ltd.

    1979-01-01

    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

    The Chilean government has determined that a renewable energy quota of up to 10% of the electrical energy generated must be met by 2024. This plan has already sparked interest in wind, geothermal, hydro and biomass power plants in order to introduce renewable energy systems to the country. Solar energy is being considered only for demonstration, small-scale CSP plants and for domestic water heating applications. This apparent lack of interest in solar energy is partly due to the absence of a valid solar energy database, adequate for energy system simulation and planning activities. One of the available solar radiation databases is 20-40 years old, with measurements taken by pyranographs and Campbell-Stokes devices. A second database from the Chilean Meteorological Service is composed by pyranometer readings, sparsely distributed along the country and available from 1988, with a number of these stations operating intermittently. The Chilean government through its National Energy Commission (CNE) has contracted the formulation of a simulation model and also the deployment of network of measurement stations in northern Chile. Recent efforts by the authors have resulted in a preliminary assessment by satellite image processing. Here, we compare the existing databases of solar radiation in Chile. Monthly mean solar energy maps are created from ground measurements and satellite estimations and compared. It is found that significant deviation exists between sources, and that all ground-station measurements display unknown uncertainty levels, thus highlighting the need for a proper, country-wide long-term resource assessment initiative. However, the solar energy levels throughout the country can be considered as high, and it is thought that they are adequate for energy planning activities - although not yet for proper power plant design and dimensioning.

  9. 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

    1980-07-01

    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)

  11. Qualitative assessment of the value of the Ohio State University TRIGA reactor

    International Nuclear Information System (INIS)

    Binney, S.E.; Johnson, A.G.

    1989-01-01

    The Oregon State University (OSU) TRIGA Reactor (OSTR) is a major regional research, training, and service facility. The OSTR supports a wide variety of organizations at the local, state, regional, national, and international levels. Examples of usage of the OSTR are given in this paper to serve as a basis for assessing the value of the OSTR to its user organizations. It is difficult to assess the value of a facility such as the OSTR quantitatively, primarily because a dollar value cannot be assigned to many of the services that the OSTR performs, e.g., forensic analysis to assist police agencies in criminal cases. Significant qualitative statements can be made, however, to demonstrate the fact that the value of a research reactor facility such as the OSTR substantially outweighs the capital and operating costs of such a facility. Analysis of the data presented above clearly indicates that the value of the OSTR facility is overwhelmingly positive, i.e., the benefits associated with the services provided by the OSTR facility outweigh the cost of providing such services by perhaps as much as an order of magnitude

    An assessment has been made of the doses that could be received by people who make use of the Cumbrian coastal area. Current doses have been estimated for residents and visitors to different parts of the area. By making assumptions about changes in waste management practices at the BNFL Sellafield plant and in the geography of the coastal area, the development of doses over the next 200 years has been assessed. The study was confined to exposure pathways in the terrestrial environment, although the influence of liquid discharges on terrestrial pathways was taken into account. Consumption of marine foodstuffs was outside the scope of the study. As expected, the highest doses would be received by those people who live closest to Sellafield. However, in all cases doses to average individuals were well below the present limit for members of the public specified by ICRP. The general future trend was for doses to decline. Doses were also estimated for particular population groups such as those who spend more time on beaches. While the resultant values were higher than those for average individuals, they were still well within the ICRP limit in all cases. (author)

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

    Maerker, Michael; Schillaci, Calogero; Melis, Rita; Mussi, Margherita

    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

    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).

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

    Frankl, P.

    2002-01-01

    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)

    The core objective of the RE-Shaping project is to assist Member State governments in preparing for the implementation of Directive 2009/28/EC (on the promotion of the use of energy from renewable sources) and to guide a European policy for RES (renewable energy sources) in the mid- to long term. The past and present success of policies for renewable energies will be evaluated and recommendations derived to improve future RES support schemes. The core content of this collaborative research activity comprises: Developing a comprehensive policy background for RES support instruments; Providing the European Commission and Member States with scientifically based and statistically robust indicators to measure the success of currently implemented RES policies; Proposing innovative financing schemes for lower costs and better capital availability in RES financing; Initiation of National Policy Processes which attempt to stimulate debate and offer key stakeholders a meeting place to set and implement RES targets as well as options to improve the national policies fostering RES market penetration; Assessing options to coordinate or even gradually harmonize national RES policy approaches. It is the objective of this report to assess the performance of Member States in promoting renewable energy technologies (RET) that has been achieved during recent years. The report was originally published in late 2010 and has now been updated using the latest available data. The focus shall be on the following aspects: Monitoring the historic success of RET-support with quantitative indicators; Extension of existing Policy Effectiveness Indicator and economic indicators; New: Deployment Status Indicator and Electricity Market Preparedness indicator; followed by Conclusions and recommendations.

    Continuous-variable quantum key distribution is a practical application of quantum information theory that is aimed at generation of secret cryptographic key between two remote trusted parties and that uses multi-photon quantum states as carriers of key bits. Remote parties share the secret key via a quantum channel, that presumably is under control of of an eavesdropper, and which properties must be taken into account in the security analysis. Well-studied fiber-optical quantum channels commonly possess stable transmittance and low noise levels, while free-space channels represent a simpler, less demanding and more flexible alternative, but suffer from atmospheric effects such as turbulence that in particular causes a non-uniform transmittance distribution referred to as fading. Nonetheless free-space channels, providing an unobstructed line-of-sight, are more apt for short, mid-range and potentially long-range (using satellites) communication and will play an important role in the future development and implementation of QKD networks. It was previously theoretically shown that coherent-state CV QKD should be in principle possible to implement over a free-space fading channel, but strong transmittance fluctuations result in the significant modulation-dependent channel excess noise. In this regime the post-selection of highly transmitting sub-channels may be needed, which can even restore the security of the protocol in the strongly turbulent channels. We now report the first proof-of-principle experimental test of coherent state CV QKD protocol using different levels Gaussian modulation over a mid-range (1.6-kilometer long) free-space atmospheric quantum channel. The transmittance of the link was characterized using intensity measurements for the reference but channel estimation using the modulated coherent states was also studied. We consider security against Gaussian collective attacks, that were shown to be optimal against CV QKD protocols . We assumed a

    Cultural competence in health care has come to the forefront with the changing demographics in the United States. Standards have been created by the Office of Minority Health for culturally appropriate health care. This article presents the findings of one hospital system's cultural competency assessment. Employee surveys and patient and physician focus groups were conducted to gain insight into cultural differences and challenges encountered in this system. Statistically significant effects of ethnicity and gender on language skills and awareness, as well as differences in awareness and knowledge by the respondent's employment position, were found. Patient concerns included access to care and respect from staff. The need for cross-cultural education and training for all health care delivery personnel was reinforced. Cultural competency will not be achieved if education, attention to diversity, trained interpreters, and the understanding that social factors have a profound influence on health and health outcomes are not considered.

    Vector-borne diseases are illnesses that are transmitted by vectors, which include mosquitoes, ticks, and fleas. The seasonality, distribution, and prevalence of vector-borne diseases are influenced significantly by climate factors, primarily high and low temperature extremes and precipitation patterns. In this presentation we summarize key findings from Chapter 5 ("Vector-borne Diseases") of the recently published USGCRP Scientific Assessment of the Impacts of Climate Change on Human Health in the United States. Climate change is expected to alter geographic and seasonal distributions of vectors and vector-borne diseases, leading to earlier activity and northward range expansion of ticks capable of carrying the bacteria that cause Lyme disease and other pathogens, and influencing the distribution, abundance and prevalence of infection in mosquitoes that transmit West Nile virus and other pathogens. The emergence or reemergence of vector-borne pathogens is also likely.

    Models of the performance of primary Li/SOCl{sub 2} cells can provide for realistic comparisons between technical information from different sources, and set standards that electronic circuit designers may refer to in the generation of high-quality products. Data from various investigators were used to derive mathematical- statistical relationships with physical design features (e.g. size and materials), operating parameters (e.g. current and temperature) and storage conditions (time and temperature). These efforts were substantially promoted by normalization procedures. For example, current loads were converted into current densities, or if appropriate, into current per unit cathode volume. Similarly, cell capacities were standardized with the maximum values observed at low current and also with respect to the cathode volume. Particular emphasis was placed on evaluations of voltage-delay, cell capacity and self-discharge, for which several equations were established. In spite of a considerable expenditure in time to find high-quality datasets, the reality is that all of the reviewed studies are flawed in one way or another. Specifically, all datasets are afflicted with sizable experimental errors and the precision of the regression equations is much lower than is deemed necessary for a universal model of the lithium thionyl chloride cell. Each of the equations has some definite truth content, but is generally incapable of bridging the gap between different studies. The basic failure to come up with a unifying model for Li/SOCl{sub 2} batteries leaves only one benefit of the present analysis, namely to provide guidance for future investigations. Several recommendations are made based on the insight gained during the search for good data in the relevant literature.

    Several direct coal liquefaction processes have been demonstrated at the pilot plant level in the United States. Presently only one plant remains operational, namely, the Hydrocarbon Technologies, Inc., 4.0- ton-per-day process development unit in Lawrenceville, New Jersey. The period from 1974 to 1982 saw the greatest amount of development of direct coal liquefaction in the United States with four major pilot plants being devoted to variants of this technology. The plants included the SRC-I plant at Wilsonville, Alabama, which operated from 1974 to 1992; the SRC-I/II plant at Fort Lewis, Washington, which operated from 1974 to 1981; the H-Coal plant at Catlettsburg, Kentucky, which operated from 1980 to 1982; and the Exxon Coal Liquefaction Pilot Plant at Baytown, Texas, which operated from 1980 to 1982. Oak Ridge National Laboratory scientists and engineers were actively involved in many phases and technical disciplines at all four of these plants, especially in materials testing, evaluation, and failure analyses. In addition, ORNL materials scientists and engineers conducted reviews of the demonstration and commercial plant designs for materials selections. The ORNL staff members worked closely with materials engineers at the pilot plants in identifying causes of materials degradation and failures, and in identifying solutions to these problems. This report provides a comprehensive summary of those materials activities. Materials performance data from laboratory and coal liquefaction pilot plant tests, failure analyses, and analyses of components after use in pilot plants were reviewed and assessed to determine the extent and causes of materials degradation in direct coal liquefaction process environments. Reviews of demonstration and commercial plant design documents for materials selections were conducted. These reviews and assessments are presented to capture the knowledge base on the most likely materials of construction for direct coal liquefaction plants.

    The Accreditation Council for Graduate Medical Education requires scholarly activity within general surgery residency programs. The association between in-training research presentations and postgraduation publications is unknown. We hypothesized that surgical trainee presentations at an American College of Surgeons (ACS) state chapter meeting resulted in peer-reviewed publications and future scholarly activity. The ACS Wisconsin state chapter meeting agendas from 2000 to 2014 were reviewed to identify all trainees who delivered podium presentations. A literature search was completed for subsequent publications. Program coordinators were queried and an electronic search was performed to determine practice location and type for each residency graduate. Wisconsin state chapter ACS meeting. General surgery residents, fellows, and medical students in Wisconsin. There were 288 podium presentations by trainees (76% residents, 20% medical students, and 4% fellows). Presentations were clinical (79.5%) and basic science (20.5%). There were 204 unique presenters; 25% presented at subsequent meetings. Of these unique presenters, 46% published their research and 31% published additional research after residency. Among presenters who completed residency or fellowship (N = 119), 34% practiced in a university setting, and 61% practiced in a community setting; 31% practiced in Wisconsin. When comparing clinical vs basic science presenters, there was no difference in fellowship completion (37% vs 44%; p = 0.190) or practice type (38% vs 46% in a university setting; p = 0.397). Repeat presenters were more likely to pursue a fellowship vs those presenting once (76% vs 37%; p = 0.001). Research presentations by surgical trainees at an ACS state chapter meeting frequently led to peer-reviewed publications. Presenters were likely to pursue research opportunities after residency. Repeat presenters were more likely to pursue a fellowship. ACS Wisconsin chapter meetings provide an

    Context Public health enabling authorities establish the legal foundation for financing, organizing, and delivering public health services. State laws vary in terms of the content, depth, and breadth of these fundamental public health activities. Given this variance, the Institute of Medicine has identified state public health laws as an area that requires further examination. To respond to this call for further examination, the Centers for Disease Control and Prevention’s Public Health Law Program conducted a fundamental activities legal assessment on state public health laws. Objective The goal of the legal assessment was to examine state laws referencing frameworks representing public health department fundamental activities (ie, core and essential services) in an effort to identify, catalog, and describe enabling authorities of state governmental public health systems. Design In 2013, Public Health Law Program staff compiled a list of state statutes and regulations referencing different commonly-recognized public health frameworks of fundamental activities. The legal assessment included state fundamental activities laws available on WestlawNext as of July 2013. The results related to the 10 essential public health services and the 3 core public health functions were confirmed and updated in June 2016. Results Eighteen states reference commonly-recognized frameworks of fundamental activities in their laws. Thirteen states have listed the 10 essential public health services in their laws. Eight of these states have also referenced the 3 core public health functions in their laws. Five states reference only the core public health functions. Conclusions Several states reference fundamental activities in their state laws, particularly through use of the essential services framework. Further work is needed to capture the public health laws and practices of states that may be performing fundamental activities but without reference to a common framework. PMID

    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)

    Full Text Available Mixed affective episodes can be misdiagnosed, especially in patients with intellectual disability (ID. We describe the case of an 18-year-old girl with mild ID, who presented with features of catatonia during the first mixed episode. These symptoms responded well to electroconvulsive therapy, following which clear affective symptoms emerged. Her affective episode did not respond adequately to olanzapine but improved significantly after the addition of sodium valproate. The difficulties of diagnosing affective episodes in persons with intellectual disabilities are discussed. This case suggests that mixed affective episodes should be considered in the differential diagnosis when poorly elaborated affective and psychotic symptoms are present in a patient with ID.

    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.

    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

    Diffuse optical spectroscopy (DOS) and diffuse optical imaging (DOI) are emerging non-invasive imaging modalities that have wide spread potential applications in many fields, particularly for structural and functional imaging in medicine. In this article, we review time-resolved diffuse optical imaging (TR-DOI) systems using solid-state detectors with a special focus on Single-Photon Avalanche Diodes (SPADs) and Silicon Photomultipliers (SiPMs). These TR-DOI systems can be categorized into two types based on the operation mode of the detector (free-running or time-gated). For the TR-DOI prototypes, the physical concepts, main components, figures-of-merit of detectors, and evaluation parameters are described. The performance of TR-DOI prototypes is evaluated according to the parameters used in common protocols to test DOI systems particularly basic instrumental performance (BIP). In addition, the potential features of SPADs and SiPMs to improve TR-DOI systems and expand their applications in the foreseeable future are discussed. Lastly, research challenges and future developments for TR-DOI are discussed for each component in the prototype separately and also for the entire system.

  13. Dressed in a Present from the Past The Transfers and Transformations of a Swedish Bridal Crown in the United States

    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.

    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.

    The physical reasons for the generation of the visible cooling tower plumes are explained. Today, there are several methods by which the visibility of the plumes can be suppressed. As the studies carried out show, a parallel connection of the wet and dry system on the air side is the most economical solution. Models for large-scale plants are presented, their operational performance is explained, and the cost is discussed. It is shown that wet/dry cooling is more economical than dry cooling alone, even with a relatively high proportion of dry heat discharge. (orig.) [de

    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 L Z -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 L Z -transform. • The proposed method provides a drastic reduction of computation burden. • Numerical example is presented in order to illustrate the method

    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

  20. Past, Present, and Future Old Growth in Frequent-fire Conifer Forests of the Western United States

    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
