    Rasmussen's encephalitis (RE) is a rare disease with unknown pathophysiology. To disclose whether anti-neuronal autoimmunity participates in the aetiology of RE, various neuronal autoantibodies (NAAbs) were investigated in sera of patients with RE and controls. The study included five patients who fulfilled the RE diagnostic criteria (clinical, EEG, and MRI findings) as the patient group, and 50 multiple sclerosis patients and 50 healthy subjects as the control groups. Sera were evaluated for various NAAbs by radioimmunoassay or cell-based assays. All sera were also screened for uncharacterized antibodies to neuronal cell surface or synapse antigens by indirect immunofluorescence using hippocampal cell cultures. The mean age at onset of seizures was 8.3±3.4 years (range: 4-13.5) and mean follow-up time was 11.2±5.4 years (range: 5-19). All patients had unihemispheric atrophy of the cerebral cortex and epilepsia partialis continua. Two of the patients had moderate cognitive impairment, while the others were severely affected, as shown by neuropsychological testing. NAAb positivity was not detected in any of the patients. Immune aetiology is thought to have a role in RE, but the responsible players have not yet been elucidated. Our extensive antibody screening in a small number of patients does not support the presence of antigen-specific anti-neuronal autoimmunity in RE pathophysiology. PMID:27248684

    2016-06-01

    Severe focal motor epilepsy is considered a clinical hallmark of Rasmussen encephalitis (RE). The authors report a 6-year-old girl with progressive right sided hemiparesis, loss of language skills, left sided hemispheric atrophy, and brain pathologic features characteristic for RE. The patient did not experience seizures over a 2year period after symptom onset and for several months during follow-up. This report expands the clinical spectrum of RE and suggests that seizures are not a universal symptom of RE. Our patient's quite remarkable neurologic deficits along with active inflammation in the absence of epilepsy supports that, at least in some individuals, unilateral hemispheric progressive inflammation can occur without active seizure activity.

    Full Text Available Rasmussen's encephalitis is a devastating syndrome of multifocal brain dysfunction and focal seizures. Magnetic resonance (MR findings, associated with clinical data and electroencephalogram (EEG, may indicate the diagnosis and could be an indicative of prognosis. We studied 5 patients with Rasmussen's encephalitis, assessing clinical history and MR images. All patients had refractory focal seizures with a predominant motor component associated with hemispheric atrophy, that was proportional to severity of disease and neurological deficits in these patients. Gray and white matter abnormal signal on T2 MR images were found in patients who had hemiparesis. It was not related to the duration of the disease but to aggressiveness. MR proton spectroscopy in severe disease showed lactate and choline increase and decreased NAA, reflecting neuronal and axonal loss, gliosis and elevated membrane turnover and recent - crisis (not controlled. MR studies, in addition to help in diagnosis, may be useful for monitoring metabolic changes and progression of disease in Rasmussen's encephalitis.A encefalite de Rasmussen é uma devastadora síndrome com disfunção cerebral multifocal e convulsões focais.

    Rasmussen encephalitis is associated with severe seizures that are unresponsive to antiepileptic drugs, as well as immunosuppressants. Transcranial direct current stimulation (t-DCS) is a non-invasive and safe method tried mostly for focal epilepsies with different aetiologies. To date, there is only one published study with two case reports describing the effect of t-DCS in Rasmussen encephalitis. Our aim was to investigate the effect of t-DCS on seizures in Rasmussen encephalitis and to clarify its safety. Five patients (mean age: 19; three females), diagnosed with Rasmussen encephalitis were included in this study. Patients received first cathodal, then anodal (2 mA for 30 minutes on three consecutive days for non-sham stimulations), and finally sham stimulation with two-month intervals, respectively. Three patients received classic (DC) cathodal t-DCS whereas two patients received cathodal stimulation with amplitude modulation at 12 Hz. Afterwards, all patients received anodal stimulation with amplitude modulation at 12 Hz. In the last part of the trial, sham stimulation (a 60-second stimulation with gradually decreasing amplitude to zero in the last 15 seconds) was applied to three patients. Maximum current density was 571 mA/m2 using 70 mm x 50 mm wet sponge electrodes with 2-mA maximum, current controlled stimulator, and maximum charge density was 1028 C/m2 for a 30-minute stimulation period. After cathodal stimulation, all but one patient had a greater than 50% decrease in seizure frequency. Two patients who received modulated cathodal t-DCS had better results. The longest positive effect lasted for one month. A second trial with modulated anodal stimulation and a third with sham stimulation were not effective. No adverse effect was reported with all types of stimulations. Both classic and modulated cathodal t-DCS may be suitable alternative methods for improving seizure outcome in Rasmussen encephalitis patients. PMID:26842560

  11. Rasmussen aneurysm - a case report in a child and review of the literature

    International Nuclear Information System (INIS)

    The authors report a case of an 11-year-old boy with a Rasmussen aneurysm presenting with dyspnea, fever and hemoptysis. The patient underwent radiological, tomographic and angiographic assessments. The pathogenesis of the aneurysm was related to the erosion of a pulmonary artery branch with replacement of the adventitia and media layers by granulation tissue, due to an adjacent tuberculous cavity. A plain chest x-ray showed bilateral nodular opacities, largest on the right lung, which enhanced simultaneously with the mediastinal vessels on CT. Its vascular nature was confirmed by angiographic studies. (author)

  12. What is the fate of disconnected brain tissue in a child with Rasmussen syndrome? A case report

    International Nuclear Information System (INIS)

    We describe a case of Rasmussen syndrome in a 7-year-old boy, presenting with epilepsia partialis continua, hemiplegia, and progressive mental deterioration. The initial MRI examination was normal, followed by progressive left hemispheric cortical atrophy and abnormal high signal intensity over the left occipital, parietal, and cingulate gyral areas over an 18-month period. On the basis of the clinical diagnosis and biopsy findings of Rasmussen syndrome, functional hemispherectomy was carried out at 7.5 years of age with alleviation of clinical seizures for the following 44 months. The follow-up MRI demonstrated atrophic changes involving the remaining left hemisphere with increased signal and cortical volume loss, as well as the absence of abnormal signal in the right hemisphere at 10 years of age. Our MRI findings are consistent with the progression of Rasmussen syndrome in the ipsilateral hemisphere even after functional-hemispherectomy without clinical seizures. (orig.)

  13. Possible universal quantum algorithms for generalized Khovanov homology and the Rasmussen's invariant

    Science.gov (United States)

    Vélez, Mario; Ospina, Juan

    2012-06-01

    Possible quantum algorithms for generalized Khovanov homology and the Rasmussen's invariant are proposed. Such algorithms are resulting from adaptations of the recently proposed Kauffman's algorithm for the standard Khovanov homology. The method that was applied consists in to write the relevant quantum invariant as the trace of a certain unitary operator and then to compute the trace using the Hadamard test. We apply such method to the quantum computation of the Jones polynomial, HOMFLY polynomial, Chromatic polynomial, Tutte polynomial and Bollobàs- Riordan polynomial. These polynomials are quantum topological invariants for knots, links, graphs and ribbon graphs respectively. The Jones polynomial is categorified by the standard Khovanov homology and the others polynomials are categorified by generalized Khovanov homologies, such as the Khovanov-Rozansky homology and the graph homologies. The algorithm for the Rasmussen's invariant is obtained using the gauge theory; and the recently introduced program of homotopyfication is linked with the super-symmetric quantum mechanics. It is claimed that a new program of analytification could be development from the homotopyfication using the celebrated Atiyah-Singer theorem and its super-symmetric interpretations. It is hoped that the super-symmetric quantum mechanics provides the hardware for the implementation of the proposed quantum algorithms.

    Rasmussen encephalitis (RE) is a chronic inflammatory disease leading to unilateral hemispheric atrophy, associated with progressive neurological dysfunction and intractable seizures. The best approach to RE is hemispherectomy. However long-term immunotherapy seems to prevent or slow down hemispheric tissue loss and the associated functional decline. We describe a girl with epilepsia partialis continua (EPC) and progressive neurological dysfunction compatible with RE. The brain MRI showed a lesion that was initially interpreted as focal cortical dysplasia. Combined antiepileptic and immunomodulation were administered for two years with initial beneficial effects. The follow-up MRI, 4 year later showed. atrophic change in right parietal region. The association of antiepileptic and immunomodulation therapies may inhibit pathogenetic mechanisms responsible for neuronal loss in RE, slowing down the progression of the disease. PMID:21885203

  17. Diagnostic imaging in 13 cases of Rasmussen's encephalitis. Can early MRI suggest the diagnosis?

    International Nuclear Information System (INIS)

    Rasmussen's encephalitis (RE) is a rare, progressive, chronic encephalitis characterised by drug-resistant epilepsy, progressive hemiparesis and mental impairment. It typically involves only one cerebral hemisphere, which becomes atrophic. We present neuroradiological findings in 13 children with RE. MRI was performed in all patients, fluorodeoxyglucose positron-emission tomography (PET) in three, Tc-99m hexamethylpropylenamine oxime single-photon emission computed tomography (SPECT) in two and proton MR spectroscopy (1HMRS) in two. MRI showed progression of the hemisphere atrophy, always prevalent in the region primarily involved (13 patients), spread of the abnormal signal in white matter (11) and cortex (10) and progression of atrophy of the head of the caudate nucleus (nine). Associated secondary changes were: atrophy of the contralateral cerebellar hemisphere (in four patients), the ipsilateral hippocampus (in five) and the brain stem (in five). The earliest CT and MRI abnormalities, seen between 1 day and 4 months after the first seizure (in 12 patients examined, nine of whom had MRI) in one cerebral hemisphere included: high signal on T2-weighted images in the cortex (seven patients) and white matter (nine), cortical atrophy usually involving the frontoinsular region, with mild or severe enlargement of the lateral ventricle (eight) and moderate atrophy of the head of the caudate nucleus (seven).

Cortical swelling in the early stage of the disease was recognisable only in two patients. PET revealed hypometabolism, SPECT decreased perfusion, and (1)HMRS reduction of N-acetylaspartate in the affected hemisphere. PET and SPECT were usually performed in the late stages and did not provide specific findings. MRI thus demonstrates the progression of RE and may suggest the diagnosis in the early stages, often before the appearance of neurological deficits. Early diagnosis of RE may be crucial for selecting patients for aggressive medical therapy or major surgical

  19. Vaccination and Infection as Causative Factors in Japanese Patients With Rasmussen Syndrome: Molecular Mimicry and HLA Class I

    Full Text Available Rasmussen syndrome is an intractable epilepsy with a putative causal relation with cellular and humoral autoimmunity. Almost half of the patients have some preceding causative factors, with infections found in 38.2%, vaccinations in 5.9% and head trauma in 8.9% of Japanese patients. In a patient with seizure onset after influenza A infections, cross-reaction of the patient's lymphocytes with GluRε2 and influenza vaccine components was demonstrated by lymphocyte stimulation test. Database analyses revealed that influenza A virus hemagglutinin and GluRε2 molecules contain peptides with the patient's HLA class I binding motif (HLA ࢤ A*0201. The relative risks of HLA class I genotypes for Rasmussen syndrome are 6.1 (A*2402, 6.4 (A*0201, 6.3 (A*2601 and 11.4 (B*4601. The relative risks of HLA class I-A and B haplotypes are infinity (A*2601+B*5401, 21.1 (A*2402+B*1501, 13.3 (A*2402+B*4801 and 5.1 (A*2402+B*5201. Some alleles and haplotypes of HLA class I may be the risk factors in Japanese patients. Cross-reactivity of cytotoxic T lymphocytes may contribute to the processes leading from infection to the involvement of CNS.

    The study carried out on behalf of former USAEC (United States Atomic Energy Commission) led by Prof. Rasmussen and published in reworked form as WASH 1400 by the USNRC (United States Nuclear Regulatory Commission) in 1975, assessed in 3,300 pages the risks that can be deducted from severe accidents in nuclear power plants. The results, often quoted and criticised, were so far the most conclusive statements to this question. In his lecture at the reactor meeting in 1976, Prof. Rasmussen tried to trace back the conclusion of the results to the question: Is the use of larger nuclear power plants, in accordance to experiences and calculations so far, acceptable? His risk assessment, related to American power plants and cites, on behalf of the BMI is currently evaluated by the IRS together with the LRA on specific occurrences within the Federal Republic of Germany.

  2. Probabilistic safety analysis of the containment spray system of Angra-1 reactor

    International Nuclear Information System (INIS)

    The calculation of the unavailability of the containment spray system of Angra-1, is done. The referred system has two different modes of operation (injection and recirculation) which were separately studied using the fault tree methodology. Besides equipment and human error failures, the contributions of test, maintenance and common-mode failures have also been considered. The quantitative evaluation was carried out by the computer code SAMPLE, which considers the uncertainties in the failures data and gives a distribution for the top event unavailability. The input data were obtained from the well-known Rasmussen Report. An importance analysis of the basic events of the trees was performed and a study of the viability of some suggestions for system design modification was also conducted. A comparison between the results obtained in this work and the corresponding ones in the Rasmussen Report has shown the fact that the unavailability of both systems are of the same order of magnitude.

  4. Radiocaesium concentration factors of Chernobyl-contaminated fish: a study of the influence of potassium, and 'blind' testing of a previously developed model

    International Nuclear Information System (INIS)

    The radiocaesium concentration factors (CF) of different fish species in 10 lakes in Russia, Belarus and Ukraine were measured between 6 and 11 yr after the Chernobyl accident. Clear inverse relations were observed between fish CF and lakewater K+ concentration. Perch (a predatory species) had CFs which were two times higher than non-predatory fish. No differences in CFs were observed between different species of non-predatory fish. An empirical model for the prediction of radiocaesium CFs in fish (Rowan and Rasmussen, 1994) was blind-tested against our measurements. The model predictions, based on measurements of K+ and suspended solids concentrations in the lakewater, were in good agreement with measured values. Our observations, however, implied a stronger effect of K+ on CF than that used in the Rowan and Rasmussen (1994) model. Further improvements in models could also be made by accounting for the effect of fish size on CF

  7. Probability and consequences of severe reactor accidents. 60th year atw

    International Nuclear Information System (INIS)

    The study carried out on behalf of former USAEC (United States Atomic Energy Commission) led by Prof. Rasmussen and published in reworked form as WASH 1400 by the USNRC (United States Nuclear Regulatory Commission) in 1975, assessed in 3,300 pages the risks that can be deducted from severe accidents in nuclear power plants. The results, often quoted and criticised, were so far the most conclusive statements to this question. In his lecture at the reactor meeting in 1976, Prof. Rasmussen tried to trace back the conclusion of the results to the question: Is the use of larger nuclear power plants, in accordance to experiences and calculations so far, acceptable? His risk assessment, related to American power plants and cites, on behalf of the BMI is currently evaluated by the IRS together with the LRA on specific occurrences within the Federal Republic of Germany.

  10. On the Nature of Severe Orographic Thunderstorms near the Andes in Subtropical South America

    Science.gov (United States)

    Rasmussen, Kristen Lani Emi

    Identifying common features and differences between the mechanisms producing extreme convection near major mountain ranges of the world is an essential step toward a general understanding of orographic precipitation on a global scale. The overarching objective of this dissertation is to understand and examine orographic convective processes in general, while specifically focusing on systems in the lee of the Andes Mountains. Diagnosing the key ingredients necessary for generating high impact weather near extreme topography is crucial to our understanding of orographic precipitating systems. An investigation of the most intense storms in 11 years of TRMM Precipitation Radar (PR) data has shown a tendency for squall lines to initiate and develop east of the Andes with a mesoscale organization similar to storms in the U.S. Great Plains (Rasmussen and Houze 2011). In subtropical South America, however, the topographical influence on the convective initiation and maintenance of the mesoscale convective systems (MCSs) is unique. The Andes and other mountainous terrain of Argentina focus deep convective initiation in the foothills of western Argentina (Romatschke and Houze 2010; Rasmussen and Houze 2011). Subsequent to initiation, the convection often evolves into propagating MCSs similar to those seen over the U.S. Great Plains sometimes producing damaging tornadoes, hail and floods across a wide agricultural region (Rasmussen and Houze 2011; Rasmussen et al. 2014b). The TRMM satellite was designed to determine the spatial and temporal variation of tropical and subtropical rainfall amounts and storm structures around the globe with the goal of understanding the factors controlling the precipitation. However, the TRMM PR algorithm significantly underestimates surface rainfall in deep convection over land (Nesbitt et al. 2004; Iguchi et al. 2009; Kozu et al. 2009). When the algorithm rates are compared to a range of conventional Z-R relations, the rain bias tends to be

  11. Water-Level Responses to Barometric-Pressure Fluctuations in Wells in Semi-Confined Aquifers

    Science.gov (United States)

    Jin, W.; Butler, J. J.

    2009-12-01

    Hydrologists have long recognized that changes in barometric pressure can produce changes in water levels in wells. The relationship between barometric pressure and water level has traditionally been characterized using the barometric efficiency (BE), the ratio of the change in water level to the change in barometric pressure head. Although BE has proven to be an effective means of characterizing the short-term response of a well to a change in barometric pressure, the barometric response function (BRF) is a more effective means to characterize the longer-term response. The BRF, which can be determined through a regression deconvolution procedure developed by Rasmussen and co-workers (Rasmussen and Crawford, 1997; Toll and Rasmussen, 2007), characterizes the water level response over time to a step change in barometric pressure, essentially BE as a function of the time since the imposed load. We have extended earlier work of Rasmussen and Spane (Rasmussen and Crawford, 1997; Spane, 2002) to show that the BRF can be utilized to glean important insights into semi-confined aquifer systems. The form of the BRF indicates the degree of aquifer confinement, while a comparison of BRFs from different wells provides insight into aquitard continuity. Recently, we have developed a new approach for estimating aquitard K by fitting type curves to experimentally determined BRFs. We will demonstrate the power of the BRF using field data from a long-term monitoring site of the Kansas Geological Survey at which a four-day pumping test has previously been performed. The aquitard K estimates obtained from the BRFs are in good agreement at this site with the estimate determined from the pumping test. We will also show how the BRF for a well in a semi-confined aquifer can be used to gain insights into conditions in the overlying unconfined aquifer and vadose zone. Although the BE is considered an invariant parameter of a well, we will show that the BRF of a well in a semi

    The pathogenesis of disease progression in drug-refractory epilepsy is poorly understood. We report the case of a young woman with a four-year history of epilepsy that progressed rapidly as evidenced by the development of progressive focal cortical atrophy. She underwent biopsy that showed perinatal ischemia and a prominent inflammatory response, including T-cell infiltration and microglial activation. There was no consensus reached on the final diagnosis although the hypothesis of dual pathology (adult variant of Rasmussen's encephalitis and perinatal stroke) was considered. The possible role of inflammation in the progression of epilepsy caused by a “static” lesion (perinatal stroke) is discussed. PMID:25667879

De acordo com os resultados, ambos os setores analisados foram considerados setores-chave com base apenas no índice de Rasmussen-Hirschman e no campo de influência, ou seja, apresentaram maior relevância quando considerados os seus impactos na demanda final e os seus poderes de encadeamento na economia. Apesar de não terem sido considerados setores-chave pelo GHS, os setores de produção e abate e processamento apresentaram grande potencialidade de impactos para trás. Em face desses resultados e dado que esses setores continuaram aumentando a sua participação na economia de Minas Gerais nos anos subseqüentes a 1995, tem-se indicação de que estes devam ter prioridade na alocação de recursos e na estratégia de promoções industriais por meio de políticas estaduais.The main objective of this study was to establish the importance and the enchainment of the production sector and butchery/making up sector of pork chain in Minas Gerais, in the years of 1980 and 1995, applying the Rasmussen-Hirschman index, the influence field index and GHS index.

Particular interest is given to the release from the reactor core at temperatures which let the fuel rod cladding burst leading to meltdown of the fuel elements and evaporation from the core melt. The special case of the steam explosion with small nuclear fuel particles pouring out into an oxidating atmosphere is touched upon. The Rasmussen study is the basis of the statements. (orig./LH)

  1. Something important is missing from PRA

    International Nuclear Information System (INIS)

    This paper provides some views on priorities and directions for the future or risk management. There are some problems with the priorities and directions that now seem dominant. Norm Rasmussen of MIT and the late Saul Levine, who was then with the U.S. Atomic Energy Commission (AEC) (the NRC's predecessor), and their colleagues deserve much credit for the invention of the art of Probabilistic Risk Assessment. Certainly the elements of risk analysis were well known and used, at least implicitly, in much of engineering and technology. But, WASH-1400, The Reactor Safety Study issued in 1975, put these elements together in a comprehensive and courageously rational way

    Full Text Available Hemispherectomy, as well as hemispherotomy, is an effective treatment for children and adolescents with drug-resistant epilepsy. The procedure is considered in children and adolescents with hemispheric damage due to congenital (e.g. malformation of cortical development, acquired (e.g. perinatal cerebral infarction or progressive diseases (e.g. Rasmussen encephalitis. As the main objective of this procedure, seizure control can be achieved in up to 80% of selected cases. Besides, the cognitive and motor function as well as the quality of life has shown good outcome. DOI: 10.3969/j.issn.1672-6731.2015.11.016

  3. Small chances - great consequences or the consequences of a large-scale accident in a nuclear power plant

    International Nuclear Information System (INIS)

    This report is a sequel to the previous Boerderijcahier (no. 7502) which discussed long-term effects of soil contamination in case of a nuclear power plant accident. In this report the short-term health effects are discussed. Models describing the local consequences of a severe accident are developed, taking into account the possible weather conditions (meteorological model), the evacuation possibilities and the inhabitability of certain areas. In each case long-term and short-term effects are discussed. The safety studies by various departments of the Netherlands' government and the Rasmussen report are commented on

  5. Advances in the evaluation of wind-induced undercatch using CFD-based simulations of snow gauge performance

    2016-04-01

    Despite its importance, accurate measurements of precipitation remains a challenge. Measurement errors for solid precipitation, which are often ignored for automated systems, frequently range from 20% to 70% due to undercatch in windy conditions. While solid precipitation measurements have been the subject of many studies, there have been only a limited number of numerical modeling efforts to estimate the collection efficiency of solid precipitation gauges when exposed to the wind, in both shielded and unshielded configurations. The available models use CFD simulations of the airflow pattern generated by the aerodynamic response of the gauge/shield geometry to perform the Lagrangian tracking of solid precipitation particles (Thériault et al., 2012; Colli et al. 2016a and 2016b). Validation of the results against field observations yields similarities in the overall behavior, but the model output only approximately reproduces the dependence of the experimental collection efficiency on wind speed. We present recent developments of such a modelling approach including various gauge/shield configurations, the influence of the drag coefficient calculation on the model performance, and the role of the particle size distribution in explaining the scatter of the collection efficiency observed at any particular wind speed (Colli et al. 2015). Comparison with observations at the Marshall (CO) field test site is used to validate results of the various modelling schemes and to support the analysis of the microphysical characteristics of ice crystals.

  10. Plant operator performance evaluation from the viewpoint of crew communications

    International Nuclear Information System (INIS)

    Elucidation of a plant operator's cognitive processes is required to improve the man-machine interface that supports operators' diagnoses and decisions. Experiments to clarify operators' cognitive processes have been performed in which operator performance under abnormal conditions was evaluated by protocol analyses and interviews using a plant dynamics simulator. The cognitive processes had been previously analyzed by using the information-processing model developed based on Rasmussen's idea. The authors have had the working hypothesis, based on the experimental observations, that crew communications can be divided into various types, and operator performance can be evaluated by analysis of crew communications. Differences in operator crew performance were evaluated in the present study

    Analyses of air trapped in polar ice cores in conjunction with recent atmospheric measurements, indicate that the atmospheric methane concentration increased by about 250% during the past two or three hundred years (Rasmussen and Khalil, 1984). Because methane is a potent ``greenhouse`` gas, the increasing concentrations are expected to contribute to global warning (Dickinson and Cicerone, 1986). The timing of the methane increase suggests that it is related to the rapid growth of the human population and associated industrialization and agricultural development. The specific causes of the atmospheric methane concentration increase are not well known, but may relate to either increases in methane sources, decreases in the strengths of the sinks, or both.

    A lattice model of critical dense polymers O(n) is considered for finite cylinder geometry. Due to the presence of noncontractible loops with a fixed fugacity ξ, the model at n=0 is a generalization of the critical dense polymers solved by Pearce, Rasmussen, and Villani. We found the free energy for any height N and circumference L of the cylinder. The density ρ of noncontractible loops is obtained for N→∞ and large L. The results are compared with those found for the anisotropic quantum chain with twisted boundary conditions. Using the latter method, we derived ρ for any O(n) model and an arbitrary fugacity.

  3. Utilization of plant operating experience in new plant designs - a consultant's viewpoint

    International Nuclear Information System (INIS)

    One specific area which should be considered in the transfer of nuclear technology to countries beginning development of a nuclear industry is the utilization and transfer of existing operating plant experience. With the event of the Rasmussen Study, a methodology now exists that can provide the systematic review of the plant design and quantify its probability of being an optimum system. Generally, the most important criteria for definition of the optimum system would be initial capital cost, projected maintenance costs, and plant availability. The fault tree analysis methodology used on the Rasmussen study allows system availability to be placed on a firm numerical footing. The area of each plant system contributing most to its unavailability is readily identifiable. Once identified, various methods for system improvement can be analyzed to determine which will provide the best results at lowest cost. The actual costs of the improvements vs the resultant savings from improved plant availability can be calculated, thus optimizing the solution. Simple financial considerations of initial costs, escalation, and overall nuclear plans provide the final loop in the iteration to establish the optimum plant design, most attention being paid to discussions of the fault-tree construction and utilization.

  4. Some useful characteristics of performance models

    International Nuclear Information System (INIS)

    This paper examines the demands placed upon models of human cognitive decision processes in application to Probabilistic Risk Assessment. Successful models, for this purpose, should, 1) be based on proven or plausible psychological knowledge, e.g., Rasmussen's mental schematic, 2) incorporate opportunities for slips, 3) take account of the recursive nature, in time, of corrections to mistaken actions, and 4) depend on the crew's predominant mental states that accompany such recursions. The latter is equivalent to an explicit coupling between input and output of Rasmussen's mental schematic. A family of such models is proposed with observable rate processes mediating the (conscious) mental states involved. It is expected that the cumulative probability distributions corresponding to the individual rate processes can be identified with probability-time correlations of the HCR Human Cognitive Reliability type discussed elsewhere in this session. The functional forms of the conditional rates are intuitively shown to have simple characteristics that lead to a strongly recursive stochastic process with significant predictive capability. Models of the type proposed have few parts and form a representation that is intentionally far short of a fully transparent exposition of the mental process in order to avoid making impossible demands on data

    Full Text Available This book by Rasmunssen examines London with an extraordinary spatial expanse, character-ized by its free and original layout, made up of the union of different towns, and with an abun-dance of free spaces. It is an interesting analysis of the British capital, which examines small urban structures such as squares with a special emphasis, as well as their attractive vertical houses. The author of the review makes note of the passion shown by Rasmussen, which causes him to forget certain defects present within the city, such as the positive view upon the continuity of the layout found in the City. The author finds this last element to be something negative, which explains the unsatisfactory present situation. It also explains the unconvincing Victorian London, which the Danish professor ignores, as well as the inability to convert the river into a true city center after having relegated Southwark to the condition of a suburb.

  10. Variation and correlation of hydrologic properties

    Energy Technology Data Exchange (ETDEWEB)

    Wang, J.S.Y. [Lawrence Berkeley Lab., CA (United States)

    1991-06-01

    Hydrological properties vary within a given geological formation and even more so among different soil and rock media. The variance of the saturated permeability is shown to be related to the variance of the pore-size distribution index of a given medium by a simple equation. This relationship is deduced by comparison of the data from Yucca Mountain, Nevada (Peters et al., 1984), Las Cruces, New Mexico (Wierenga et al., 1989), and Apache Leap, Arizona (Rasmussen et al., 1990). These and other studies in different soils and rocks also support the Poiseuille-Carmen relationship between the mean value of saturated permeability and the mean value of capillary radius. Correlations of the mean values and variances between permeability and pore-geometry parameters can lead us to better quantification of heterogeneous flow fields and better understanding of the scaling laws of hydrological properties.

    Healthcare is a complex adaptive system. This paper discusses, healthcare in the context of complex systems architecture and an agent based modeling framework. The paper demonstrates complications of healthcare system improvement and it's impact on patient safety, economics and workloads. Further an application of safety dynamics model proposed by Cook and Rasmussen4 is explored using a hypothetical simulation of an emergency department. By means of simulation, this paper demonstrates the nonlinear behaviors of a health service unit and its complexities; and how the safety dynamic model may be used to evaluate various aspects of healthcare. Further work is required to apply this concept in a 'real life environment' and its consequence to societal, organizational and operational levels of healthcare.

  16. Accidents, probabilities and consequences

    International Nuclear Information System (INIS)

    Following brief discussion of the safety of wind-driven power plants and solar power plants, some aspects of the safety of fast breeder and thermonuclear power plants are presented. It is pointed out that no safety evaluation of breeders comparable to the Rasmussen investigation has been carried out and that discussion of the safety aspects of thermonuclear power is only just begun. Finally, as an illustration of the varying interpretations of risk and safety analyses, four examples are given of predicted probabilities and consequences in Copenhagen of the maximum credible accident at the Barsebaeck plant, under the most unfavourable meterological conditions. These are made by the Environment Commission, Risoe Research Establishment, REO (a pro-nuclear group) and OOA (an anti-nuclear group), and vary by a factor of over 1000. (JIW)

  20. Minimizing the human error rate by understanding the relationship between skill and rule-based errors

    International Nuclear Information System (INIS)

    The rate of equipment failure caused events at nuclear power plants has been decreasing steadily, while the rate of human error caused events has not been decreasing nearly as rapidly. Using the skill-rule-knowledge based model of Rasmussen, many day-to-day operations are classified as skill-based actions and, consequently most of the errors in day-to-day operations are skill-based errors. In order to reduce the rate of skill-based errors, rules (procedures, forms, and checklists) have been developed. However, the increasing complexity and redundancy in rules leads to an increasing rate of errors in making rules and in carrying them out. To minimize the error rate, a compromise must be chosen. This article suggests a practical method to understand why human error caused events are not decreasing as rapidly as equipment caused events, and how to develop effective actions to reduce the human error rate

    Gil et al. (2015) present new and existing data in core OCE326 GGC14 from the Laurentian Fan off of the Laurentian Channel. In their study, they criticize data published from the same core by Obbink et al. (2010) and from a nearby core by Carlson et al. (2007). One major conclusion of Gil et al. (2015) is that "The YD [Younger Dryas cold event; 12.9-11.7 ka; Rasmussen et al., 2006] cannot be regarded as an event triggered by a fresh water input through the Laurentian Channel since only a weak brief input nearly 1000 yrs after its onset is recorded." Here we show that their study misrepresents existing data, and ignores their own data and its uncertainty, which leads to different conclusions than in Gil et al. (2015).

  11. Dose rate calculations inside the containment shell of a PWR in case of an accident

    International Nuclear Information System (INIS)

    The aim of the study is the evaluation of γ dose rates. In view to treat the different aspects of partial or total melting of the reactor core, leading to emission of a great quantity of fission radioactive products in the containement shell, implying the loss of integrity of the first two containement barriers, the study comprises: 1) Calculation of the γ dose rate as a function of time, normalized in considering a total release of fission products present in the core at the moment of the accident: it is done by taking into account the fission products in suspension in the containement shell, deposited on the internal surfaces and trapped by the water drain. 2) Transfer hypotheses of fission products (the release kinematics are linked to the accident scenario). The hypotheses of emission and deposit in this work are those of Rasmussen

  13. Cognitive process in plant diagnosis using an operator cognitive model

    International Nuclear Information System (INIS)

    An operator cognitive model has been constructed referring to Rasmussen's ladder model, and a simulation system of operator performance has been developed. Computer simulation was then performed to investigate subjects' behavior in a cognitive experiment concerning PWR nuclear power plant diagnosis. The knowledge bases used in the simulation were constructed from the interview to the subjects. Confidence on each hypothesis and performance history of operators were compared between the experiment and the simulation, and the simulation could well explain the behavior of the subjects in the results of event identification, confidence on the results, hypotheses conceived during diagnosis, and plant parameters observed, which indicates the validity of the operator model. The order of parameter observation, however, disagreed, and it has been clearly shown that knowledge on system configuration of the plant as well as the physical layout of interface should be considered.

    Full Text Available Birgit Brander Rasmussen’s Queequeg’s Coffin: Indigenous Literacies and Early American Literature is a fascinating discussion of various non-alphabetic writing by indigenous peoples. According to its blurb, it “recovers previously overlooked moments of textual reciprocity in the colonial sphere, from a 1645 French-Haudenosaunee Peace Council to Herman Melville’s youthful encounters with Polynesian hieroglyphics.” The text reproduced here takes on Melville’s iconic novel Moby Dick and explores Ishmael’s description of the tattoos on the body of the Polynesian harpooner Queequeg and on his coffin. Rasmussen posits these as a fictionalized embodiment of actual Polynesian writing.

  5. Applying the Skill-Rule-Knowledge Framework to Understanding Operators’ Behaviors and Workload in Advanced Main Control Rooms

    International Nuclear Information System (INIS)

    Highlights: • Operator behaviors were analyzed according to Rasmussen's SRK classification. • Different job positions connote different abilities to perform the job successfully. • Rule-based behavior comprised the main behavior patterns of the operating crew. - Abstract: For the past years, a number of researches have focused on operators’ behaviors and workloads in advanced main control rooms (MCRs) in either the procedure-domain or knowledge-domain and in either workload-increased or workload-decreased conditions. Different job positions connote different responsibilities and abilities that are required to perform the job successfully. However, it may be inappropriate to apply a dichotomy in these issues. In this study, we clarified these controversial points through the analysis of the time, frequency, and workload of the behaviors based on Rasmussen's skill–rule–knowledge classification (SRK framework) according to the supervisor operator (SRO), reactor operator (RO), and assistant reactor operator (ARO). The results showed that, for the SRO, rule- and knowledge-based behaviors occurred more often than skill-based behavior in terms of time and frequency, and knowledge-based behavior was the main source of workload. For the RO, no significant differences were found among the three behavior types in terms of frequency and workload, but more time was spent on rule-based behaviors than on skill- and knowledge-based behaviors. The ARO spent more time performing skill-based behaviors than rule- and knowledge-based behaviors, but in terms of frequency and workload, rule-based behavior was the predominant type. Operators’ behaviors contribute to a plant's defense-in-depth approach to safety and serve a vital function in ensuring its safe operation. Research on behavioral taxonomies of advanced MCRs has many significant benefits in both scientific-theoretical and applied practical fields

    Highlights: • Operator behaviors were analyzed according to Rasmussen's SRK classification. • Different job positions connote different abilities to perform the job successfully. • Rule-based behavior comprised the main behavior patterns of the operating crew. - Abstract: For the past years, a number of researches have focused on operators’ behaviors and workloads in advanced main control rooms (MCRs) in either the procedure-domain or knowledge-domain and in either workload-increased or workload-decreased conditions. Different job positions connote different responsibilities and abilities that are required to perform the job successfully. However, it may be inappropriate to apply a dichotomy in these issues. In this study, we clarified these controversial points through the analysis of the time, frequency, and workload of the behaviors based on Rasmussen's skill–rule–knowledge classification (SRK framework) according to the supervisor operator (SRO), reactor operator (RO), and assistant reactor operator (ARO). The results showed that, for the SRO, rule- and knowledge-based behaviors occurred more often than skill-based behavior in terms of time and frequency, and knowledge-based behavior was the main source of workload. For the RO, no significant differences were found among the three behavior types in terms of frequency and workload, but more time was spent on rule-based behaviors than on skill- and knowledge-based behaviors. The ARO spent more time performing skill-based behaviors than rule- and knowledge-based behaviors, but in terms of frequency and workload, rule-based behavior was the predominant type. Operators’ behaviors contribute to a plant's defense-in-depth approach to safety and serve a vital function in ensuring its safe operation. Research on behavioral taxonomies of advanced MCRs has many significant benefits in both scientific-theoretical and applied practical fields.

  7. The role of climate in balancing soil production and sediment yield in New Zealand

    New Zealand hosts some of the highest specific sediment yields on the planet reaching up to nearly 30,000 t km-2 yr-1. Sediment yields measure the export of sediment from a basin and give an indication of erosion from hillslopes. In New Zealand high sediment yields correlate with high annual precipitation and high rates of tectonic strain (Hicks et al., 1996). It is, however, unclear how soil production keeps pace with such extreme erosion. Here, this question is investigated by modelling soil production as a function of local climate parameters. Two simple models for building climate into soil production are through effective energy and mass transfer, EEMT, (Rasmussen and Tabor, 2007) and primary chemical weathering. When applied to ~30 year climate data, these models highlight the variability of potential soil production across New Zealand. Due partially to high annual rainfall, some of the fastest erosion rates on the west coast of the South Island are nearly in balance with soil production. In other regions such as the east coast of the North Island, hotspots exist where annual sediment yields exceed reasonable soil production rates such that additional mechanisms must operate to generate sediment and make up this deficit. Globally, precipitation tends to increase and temperature decreases with increasing elevation. In New Zealand, increasing elevations also roughly correlate with an increase in mean basin slope angle and the percent of a basin at >30° slopes. As a result, modelled soil production also tends to increase with increasing mean basin slope angle. This correlation occurs independent of erosion feedbacks on the modelled soil production rates. This relationship presents an intriguing scenario in which the topography of the mountain range may be maintained by climate through variations in soil production. Even with rapid modelled soil production at high precipitation rates and/or high temperatures and/or high temperatures, many basins cannot keep pace

    Two parameters have been added to the Extended UNIQUAC model of Thomsen and Rasmussen [Thomsen, K., Rasmussen, P., 1999. Modeling of vapor-liquid-solid equilibrium in gas-aqueous electrolyte systems. Chem. Eng. Sci. 54, 1787-1802] to account for the pressure dependency of mineral solubility. The improved model has been used for correlating and predicting vapor-liquid-solid equilibrium for different carbonate systems (CaCO{sub 3}, MgCO{sub 3}, BaCO{sub 3} and SrCO{sub 3}) causing mineral scaling problems. The solubility of NaCl and CO{sub 2} in pure water and the solubility of CO{sub 2} in NaCl and Na{sub 2}SO{sub 4} solutions have also been correlated. The results show that the Extended UNIQUAC model, with the added pressure parameters, is able to represent binary (NaCl-H{sub 2}O, CaCO{sub 3}-H{sub 2}O, BaCO{sub 3}-H{sub 2}O, SrCO{sub 3}-H{sub 2}O, MgCO{sub 3}-H{sub 2}O, Mg(OH){sub 2}-H{sub 2}O and CO{sub 2}-H{sub 2}O), ternary (CaCO{sub 3}-CO{sub 2}-H{sub 2}O, BaCO{sub 3}-CO{sub 2}-H{sub 2}O, SrCO{sub 3}-CO{sub 2}-H{sub 2}O, MgCO{sub 3}-CO{sub 2}-H{sub 2}O, CO{sub 2}-NaCl-H{sub 2}O and CO{sub 2}-Na{sub 2}SO{sub 4}-H{sub 2}O), and quaternary (CO{sub 2}-NaCl-Na{sub 2}SO{sub 4}-H{sub 2}O) solubility data within the experimental accuracy in the range of temperatures and pressures considered in the study, i.e. from 0 to 250{sup o}C, and from 1 to 1000bar, respectively. The modified Extended UNIQUAC model will be a useful tool for predicting and quantifying the scaling problems that may occur in wells and surface equipment during geothermal operations. This would allow adequate preventive measures to be taken before mineral deposition becomes troublesome. (author)

    Full Text Available The classic “Halstedian” apprenticeship model for surgical training takes place into the operating theater under the strict coordination of a senior surgeon. The development of minimally invasive surgery (MIS rapidly revealed that this apprenticeship model is insufficient to successful fulfill the well known three stages of training of Rasmussen model – skill-based behavior (SBB, rule-based behavior (RBB and knowledge-based behavior (KBB – due to ethical, medico-legal and economic considerations and a specific training using different methods (theoretical and hands-on courses using simulators, animal models and web resources is mandatory. However it isn’t a worldwide accepted laparoscopic training curriculum. We present our experience with different types of teaching methods; in this way we retrospectively reviewed our experience in laparoscopic education, presenting data using Rasmussen model, as a dynamic three stages model: 1 first stage (the beginning, from 1993 until 1995, our staff acquired SBB, RBB and KBB for basic MIS procedures: cholecystectomy, appendectomy, surgical ablation of ovarian cysts; 2 the second stage, from 1996 until 1999, characterized by continuous training of our surgical staff until the achievement of the KBB level for basic MIS procedures and training for other operations (laparoscopic treatment of the groin hernias, eso-gastric and bariatric surgery and the teaching of the residents and the surgeons from Moldova region to achieve SBB and RBB for basic MIS procedures; 3 the third stage, from 2000 until present characterized by a continuous improvement of the surgical teams’ laparoscopic skills for different procedures, and developing a modern curricula for laparoscopic education. CONCLUSIONS: There is no universal method for laparoscopic training. Our experience demonstrates good results using a combination of training methods which allowed acquiring: SBB (Basic skills using virtual reality (VR simulators

  10. Nuclear structure research. Annual progress report

    International Nuclear Information System (INIS)

    The most significant development this year has been the realization that EO transition strength is a fundamental manifestation of nuclear mean-square charge radius differences. Thus, EO transitions provide a fundamental signature for shape coexistence in nuclei. In this sense, EO transitions are second only to E2 transitions for signaling (quadrupole) shapes in nuclei and do so when shape differences occur. A major effort has been devoted to the review of EO transitions in nuclei. Experiments have been carried out or are scheduled at: ATLAS/FMA (α decay of very neutron-deficient Bi isotopes); MSU/NSCL (β decay of 56Cu); and HRIBF/RMS (commissioning of tape collector, internal conversion/internal-pair spectrometer; β decay of 58Cu). A considerable effort has been devoted to planning the nuclear structure physics that will be pursued using HRIBF. Theoretical investigations have continued in collaboration with Prof. K. Heyde, Prof. D.J. Rowe, Prof. J.O. Rasmussen, and Prof. P.B. Semmes. These studies focus on shape coexistence and particle-core coupling

  11. Simulation and dynamics of entropy-driven, molecular self-assembly processes

    International Nuclear Information System (INIS)

    Molecular self-assembly is frequently found to generate higher-order functional structures in biochemical systems. One such example is the self-assembly of lipids in aqueous solution forming membranes, micelles, and vesicles; another is the dynamic formation and rearrangement of the cytoskeleton. These processes are often driven by local, short-range forces and therefore the dynamics is solely based on local interactions. In this paper, we introduce a cellular automata based simulation, the lattice molecular automaton, in which data structures, representing different molecular entities such as water and hydrophilic and hydrophobic monomers, share locally propagated force information on a hexagonal, two-dimensional lattice. The purpose of this level of description is the simulation of entropic and enthalpic flows in a microcanonical, molecular ensemble to gain insight about entropy-driven processes in molecular many-particle systems. Three applications are shown, i.e., modeling structural features of a polar solvent, cluster formation of hydrophobic monomers in a polar environment, and the self-assembly of polymers. Processes leading to phase separation on a molecular level are discussed. A thorough discussion of the computational details, advantages, and limitations of the lattice molecular automaton approach is given elsewhere [B. Mayer and S. Rasmussen (unpublished)]. copyright 1997 The American Physical Society

  12. Representing cognitive activities and errors in HRA trees

    International Nuclear Information System (INIS)

    This paper discusses development of a means by which to present cognitive information in human reliability assessment (HRA) event trees. The descriptions found in probabilistic risk assessments (PRAs) regarding the demands on, and the resulting performance of, nuclear power plant (NPP) crews often make use of the technique for human error rate prediction (THERP), which provides a mechanism, the HRA event tree, for presenting the analyst's conceptualization of the activities underlying performance and the errors associated with that performance. When using THERP, analysts have often omitted the more complex elements of human cognition from these trees. There has yet to be a concerted effort to take theory, principles, and data from cognitive psychology and wed it to the logic structure of the HRA event tree. This paper attempts to do so. The COGENT modeling scheme (cognitively based HRA event trees) adds two taxonomies to the HRA event tree proposed by Swain and Guttman. The first taxonomy, the one proposed by Norman and Reason, describes the type of error committed and implies something about the underlying cognition as well. The second of these, the Rasmussen taxonomy, provides description regarding the skill-based, rule-based, or knowledge-based behavior underlying the execution of tasks. It is not apparent and must be deduced from the pattern of errors exhibited by personnel

    Burlington Bottoms, consisting of approximately 417 acres of riparian and wetland habitat, was purchased by the Bonneville Power Administration in November 1991. The site is located approximately 1/2 mile north of the Sauvie Island Bridge (T2N R1W Sections 20, 21), and is bound on the east side by Multnomah Channel and on the west side by the Burlington Northern Railroad right-of-way and U.S. Highway 30 (Figures 1 and 2). Wildlife habitat values resulting from the purchase of this site will contribute toward the goal of mitigating for habitat lost as outlined in the Columbia and Willamette River Basin's Fish and Wildlife Program and Amendments. Under this Program, mitigation goals were developed as a result of the loss of wildlife habitat due to the development and operation of Federal hydro-electric facilities in the Columbia and Willamette River Basins. In 1993, an interdisciplinary team was formed to develop and implement quantitative Habitat Evaluation Procedures (HEP) to document the value of various habitats at Burlington Bottoms. Results of the HEP will be used to: (1) determine the current status and habitat enhancement potential of the site consistent with wildlife mitigation goals and objectives; and (2) develop a management plan for the area. HEP participants included; Charlie Craig, BPA; Pat Wright, Larry Rasmussen, and Ron Garst, U. S. Fish and Wildlife Service; John Christy, The Nature Conservancy; and Doug Cottam, Sue Beilke, and Brad Rawls, Oregon Department of Fish and Wildlife.

  14. Comparison of the THERP quantitative tables with the human reliability analysis techniques of second generation

    International Nuclear Information System (INIS)

    The methodology THERP is classified as a Human Reliability Analysis (HRA) technique of first generation and its emergence was an important initial step for the development of HRA techniques in the industry. Due to the fact of being a first generation technique, THERP quantification tables of human errors are based on a taxonomy that does not take into account the human errors mechanisms. Concerning the three cognitive levels in the Rasmussen framework for the cognitive information processing in human beings, THERP deals in most cases with errors that happen in the perceptual-motor level (stimulus-response). In the rules level, this technique can work better using the time dependent probabilities curves of diagnosis errors, obtained in nuclear power plants simulators. Nevertheless, this is done without processing any error mechanisms. Another deficiency is the fact that the performance shaping factors are in limited number. Furthermore, the influences (predictable or not) of operational context, arising from operational deviations of the most probable (in terms of occurrence probabilities) standard scenarios beside the consequent operational tendencies (operator actions) are not estimated. This work makes a critical analysis of these deficiencies and it points out possible solutions in order to modify the THERP tables, seeking a realistic quantification, that does not underestimate or overestimate the human errors probabilities when applying the HRA techniques to nuclear power plants. The critical analysis is accomplished through a qualitative comparison between THERP, a HRA technique of first generation, with CREAM, as well as ATHEANA, which are HRA techniques of second generation.

  16. The dual face of reactor safety

    International Nuclear Information System (INIS)

    Reactor safety is nowadays treated theoretically by a probabilistic approach. This means that events which may lead to accidents are considered as random events, and probability calculus is employed to predict potential damage. However, it has been found in practice that there are also failures in no way connected with chance, i.e., the so-called deterministic ones. This lends a dual face to reactor safety, a probabilistic and a deterministic one. In this contribution, the author resumes studies he had once initiated under the heading of Deterministic and Probabilistic Theses on Reactor Safety. He examines the present state of reactor safety under the aspect of deterministic and probabilistic failures and the significance of active and passive safety systems, estimating whether and to what extent earlier proposals have been incorporated in present technology. The two most prominent studies dealing with the risk of nuclear power plants, the American Rasmussen Study, WASH 1400, and the German Risk Study, were calculated by the most recent probabilistic methods. The causes of deterministic failures can be traced back to deterministic errors. There are errors in planning, in design, in fabrication, errors caused by maloperation, premature aging, sabotage and war. Since they are due to certain causes, it is possible in principle to discover and control them already by mental experiments. (orig./HP)

  17. On the characterization of risk

    International Nuclear Information System (INIS)

    The concept of risk is associated with the concepts of event, harmful consequence, and probability. Initiating events and their possible developments, together with their associated probabilities, induce a probability space on the space of consequences. The risk is defined as a probability density function (or distribution) on the space of harmful consequences. The risks involved in nuclear power plants are taken as an example. Possible presentations of the risk (e.g. radiation-dose space and health-effects space) are discussed and the relationship between them is analysed. The relationship of some presentations in common use (such as the presentation of the risk in the Rasmussen report) to the above definition of the risk is also discussed. Some of the implications of the definition are explored further and the different receptors of risk, social and personal risks, and the possibility (or impossibility) of comparing risks are discussed. Ways of refining the description of the risk in risk assessments are outlined as an application of the definition. It is argued that personal risk, social risk, and correlations between consequences are necessary. (author)

    Previous research has emphasized the need to consider the social dimension featuring organizations in order to maximize organizational efficiency (Rasmussen, 1997). In the road transport sector, previous research has focused on the relationship between human factor, stress, fatigue, and other relevant issues, and professional drivers health and safety (p.e., De Croon et al, 2004). However, research on relevant organizational factors is scarce. This study aims to examine the association between leadership and supportive climate, and employees health and safety. Moreover, the impact of stress (time pressure) was also examined because previous research has stressed its importance. This study used a sample of 486 employees from 35 different Spanish companies pertaining to the road transport sector. Findings showed time pressure to be negatively associated to employees health, job satisfaction and satisfaction with safety. Additionally, leadership was positively associated employees health, job satisfaction and satisfaction with safety. Finally, co-workers and supervisors supportive climate was positively associated with job satisfaction and negatively associated to illness. These findings have relevant practical implications for the competitiveness of road transport companies. (Author) 21 refs.

  19. Results of comparative evaluations concerning the psychic process of perceiving and assessing risk-objects by the general public

    International Nuclear Information System (INIS)

    The perception of risk has become a mayor research field, after scientists and politicians recognized that scientific risk studies like the Rasmussen-Report on nuclear energy had no large impact on the public acceptance. With our surveys we aimed to combine two methodological approaches (object perception and attitude theory) and to develop a technique in which the psychic process of perceiving and assessing risk-objects by the general public was followed up and analyzed. Psychological experiments in the field of isolating relevant factors of qualitative risk properties as well as demographic surveys for the measurement of the belief structure were carried out. Our results indicate that in objection to the common conception by natural scientists people in general have a good estimative ability to judge the expected value of different risks. But beyond this estimation of fatalities people also use other criteria (like personal control) to order different objects in respect to their riskiness. The perceived risk is but one factor influencing attitude. A simplified model of the acceptance-building process is carried out showing that acceptance-building is not a purely individual process. Individuals are linked together by their social environment so that every individual decision is influenced by the decision of other people

    Between August of 1997 and December of 2001, they were treated in the orthopedics department and traumatology of the Hospital Clinica San Rafael, 16 patients with proximal complex fractures of the tibia, using internal fixation with plate in the lateral column and an unilateral external fixer, for the medial column. It carries out a clinical and radiological pursuit with average of 27 months (minimum 4.5, maximum 40 months). In 15 patients (93,7%) it was obtained a primary consolidation and 1 case (6,2%) it presented retard in the consolidation being necessary the placement of bony implants. in 2 cases (12,5%) there was superficial infection, one in the itinerary of the nails and another in area of superficial necrosis in soft fabrics in a closed fracture. single 1 case (6,2) it presented deep infection, which, it improve with bony curettage and antibiotics. In the final radiographic evaluation, 2 cases (12,5%) they presented depression of the lateral plate; according to the functional scale of Rasmussen excellent results were obtained (27 to 30 points) in 11 cases (68,7%) and good (20 to 26 points) in 5 cases (31,2%). The radiographic results and functional global they suggest that the combination of a technique less invasive in this area criticizes, it represents a good alternative for the treatment of the proximal complex fractures of the tibia

  1. Environmental aspects of nuclear power applications

    International Nuclear Information System (INIS)

    The paper estimates the future dangers from the nuclear industry. Historically, the occurrence of nuclear reactor accidents has not been a hazard to the U.S. population, because of relatively limited reactor deployment and because of relatively safe operation. Some factual inputs were taken from the Rasmussen Report, ''An Assessment of Accident Risks in U.S. Commercial Nuclear Power Plants.'' It is noted that data on nuclear power plant accidents follow a curve about four orders of magnitude below that for persons on the ground killed by air crashes. Data show that coal mining produced about ten times as many disabilities as uranium mining and milling per 106 MW(e)h of energy recovered, while the number of injuries per 106 man-hours of work was roughly comparable for these two types of occupations. Information on the following subjects is then presented: radiation protection standards, radiation exposures; radiation emitted from nuclear reactors under normal operating conditions; accidents involving nuclear fission reactors; fuel reprocessing; nuclear waste disposal; estimates of environmental and safety aspects of fusion power; licensing of nuclear reactors; nuclear safeguards: diversion of nuclear materials, sabotage, and subversion; and nuclear energy and trade deficits in which data are presented estimating a timetable expressing the economic power of OPEC, or the time required for OPEC wealth to purchase the world's major assets

    Objective: To report the clinical outcome of arthroscopically assisted treatment for tibial plateau fractures.Methods: A total of 39 patients with tibial plateau fractures were treated by arthroscopic fixation from February 2002 to December 2005,including 11 patients with bony avulsion of the anterior cruciate ligament and 19 with meniscal injury.There were 4 cases of type I fracture,12 type II,9 type III,12 type IV and 2 type V according to Schatzker criteria.Firstly,the combined injuries were treated.Then the plateau fractures with the displacement over 3 mm or more were reduced and fixed.Finally,the internal fixation was observed by X-ray equipment.Postoperative management was early motion and delayed weight bearing.Results: All the fractures healed in 3 or 4 months.All patients were followed up for 1 to 5 years after operation.No case had severe complications,such as poor wound healing,infection,osteofascial compartment syndrome and osteoarthritis.According to the Rasmussen scoring system,36 cases obtained excellent or good results and the other 3 cases had moderate clinical results.The average score was 26 ± 3.Conclusions: As an adjuvant treatment of intraarticular fractures such as tibial plateau fracture,arthroscopy has many advantages.It can treat associated intraarticular soft tissue components,visualize the chondral surface reduction,lavage the hematoma and smaller loose fragments,decrease soft tissue dissection,reduce the risk of scarring and promote rapid recovery.

  3. Reactor safety study. An assessment of accident risks in U.S. commercial nuclear power plants. Executive summary

    International Nuclear Information System (INIS)

    The Reactor Safety Study was sponsored by the U. S. Atomic Energy Commission to estimate the public risks that could be involved in potential accidents in commercial nuclear power plants of the type now in use. It was performed under the independent direction of Professor Norman C. Rasmussen of the Massachusetts Institute of Technology. The risks had to be estimated, rather than measured, because although there are about 50 such plants now operating, there have been no nuclear accidents to date resulting in significant releases of radioactivity in U.S. commercial nuclear power plants. The objective of the study was to make a realistic estimate of these risks and, to provide perspective, to compare them with non-nuclear risks to which our society and its individuals are already exposed. This information may be of help in determining the future reliance by society on nuclear power as a source of electricity. The results from this study suggest that the risks to the public from potential accidents in nuclear power plants are comparatively small

    The aim of this study was the assessment of detection rate on MRI and description of MRI findings in patients with medically intractable epilepsy. Seventy-three patients with medically intractable epilepsy between the ages of 0 and 68 years old were evaluated by MRI, on three planes with spin-echo T1, fast spin-echo T2, and fluid-attenuated inversion recovery sequences, and, if necessary, with contrast-enhanced SE T1 sequences. Cerebral infarct regions with atrophy and gliosis in 8 patients, cerebral tumors in 5 patients, hippocampal sclerosis in 16 patients, radial microbrain in 1 patient, cortical dysplasia in 3 patients, pachygyria in 2 patients, subcortical heterotopia in 2 patients, schizencephaly in 3 patients, cerebral hemiatrophy in 2 patients, tuberous sclerosis in 1 patient, herpes encephalitis in 2 patients, Rasmussen's encephalitis in 1 patient, vascular malformations in 5 patients, and no abnormality in 22 patients were detected. Magnetic resonance imaging has a high success rate in detecting structural brain abnormalities, of both temporal and extratemporal locations, associated with medically intractable epilepsy syndromes. So MRI plays a primary role in planning of the treatment, primarily surgical therapy, by detecting structural epileptogenic lesions. (orig.)

  7. Human reliability assessment on the basis of operating experience

    International Nuclear Information System (INIS)

    For development of methodology, available models for qualitative assessment of human errors (e.g. by Swain, Hacker, Rasmussen) and a variety of known systematic approaches for quantitiative assessment of inadequate human action (e.g. THERP, ASEP, HCR, SLIM) were taken as a basis to establish a job specification, which in turn was used for developing a method for acquisition, characterisation and evaluation of errors. This method encompasses the two processes of event analysis and event evaluation: The first step comprises analysis of events by analysis of information describing the conditions and scenarios of relevance to the inadequate human action examined. In addition to the description of process sequences, information is taken into account on possible conditions that may bring about failure. As an assessment of human reliability requires manifold approaches for evaluation, a connectionistic procedure was developed for evaluation of the compilation of events based on a debate about various approaches from the domain of artificial intelligence (AI). This procedure yields both qualitative and quantitative information through a homogenous approach. (orig./GL)

    Instead of ATCG letter alignments, typically used in bioinformatics, we propose a new alignment method using the probability distribution function of the bottom of the occupied molecular orbital (BOMO), highest occupied molecular orbital (HOMO) and lowest unoccupied orbital (LUMO). We apply the technique to transcription factors with Cys2His2 zinc fingers. These transcription factors search for binding sites, probing for the electronic patterns at the minor and major DNA groves. The eukaryotic Cys2His2 zinc finger proteins bind to DNA ubiquitously at highly conserved domains. They are responsible for gene regulation and the spatial organization of DNA. To study and understand these zinc finger DNA-protein interactions, we use the extended ladder in the DNA model proposed by Zhu, Rasmussen, Balatsky & Bishop (2007) te{Zhu-2007}. Considering one single spinless electron in each nucleotide π-orbital along a double DNA chain (dDNA), we find a typical pattern for the bottom of BOMO, HOMO and LUMO along the binding sites. We specifically looked at two members of zinc finger protein family: specificity protein 1 (SP1) and early grown response 1 transcription factors (EGR1). When the valence band is filled, we find electrons in the purines along the nucleotide sequence, compatible with the electric charges of the binding amino acids in SP1 and EGR1 zinc finger.

    Full Text Available Helen M Rasmussen,1 Elizabeth J Johnson2 1Educational Studies, Lesley University, Cambridge, MA, USA; 2Carotenoid and Health Laboratory, Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging at Tufts University, Boston, MA, USA Abstract: The incidence of age-related eye diseases is expected to rise with the aging of the population. Oxidation and inflammation are implicated in the etiology of these diseases. There is evidence that dietary antioxidants and anti-inflammatories may provide benefit in decreasing the risk of age-related eye disease. Nutrients of interest are vitamins C and E, β-carotene, zinc, lutein, zeaxanthin, and the omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid. While a recent survey finds that among the baby boomers (45–65 years old, vision is the most important of the five senses, well over half of those surveyed were not aware of the important nutrients that play a key role in eye health. This is evident from a national survey that finds that intake of these key nutrients from dietary sources is below the recommendations or guidelines. Therefore, it is important to educate this population and to create an awareness of the nutrients and foods of particular interest in the prevention of age-related eye disease.

  10. Use of probabilistic risk assessment in expert system usage for nuclear power plant safety

    International Nuclear Information System (INIS)

    The introduction of probability risk assessments (PRA's) to nuclear power plants in the Rasmussen Report (WASH-1400) gave us a means of evaluating the risk to the public associated with the operation of nuclear power plants, at least on a relative basis. While the choice of the ''source term'' and methodology in a PRA significantly influence the absolute probability and the consequences of core melt, comparison of two PRA calculations for two configurations of the same plant, carried out on a consistent basis, can be readily identify the increase in risk associated with going from one configuration of a plant to another by removing components or systems from service. This ratio of core melt probabilities (assuming no recovery of failed systems) obtained from two PRA calculations for different configurations was the criterion (called ''risk factor'') chosen as a basis for making a decision in an expert system as to what mitigating action, if any, would be taken to avoid a trip situation from developing. PRISIM was developed by JBF Associates of Knoxville under the sponsorship of the NRC as a system for Resident Inspectors at nuclear power plants to provide them with a relative safety status of the plant under all configurations. PRISIM calculated the risk factor---the ration of core melt probabilities of the plant under the current configuration relative to the normal configuration with all systems functioning---using an algorithm that emulates the results of the original PRA. It also presents time and core melt (assuming no recovery of systems or components)

    The extrathoracic airways, including the nasal passage, oral passage, pharynx, and larynx, are the first targets for inhaled particles and provide an important defense for the lung. Understanding the deposition efficiency of the nasal and oral passages is therefore crucial for assessing doses of inhaled particles to the extrathoracic airways and the lung. Significant inter-subject variability in nasal deposition has been shown in recent studies by Rasmussen, T.R. et al, using 2.6 {mu}m particles in 10 human subjects and in our preliminary studies using 0.004-0.15 {mu}m particles in four adult volunteers. No oral deposition was reported in either of these studies. Reasons for the intersubject variations have been frequently attributed to the geometry of the nasal passages. The aims of the present study were to measure in vivo the nasal airway dimensions and the deposition of ultrafine aerosols in both the nasal and oral passages, and to determine the relationship between nasal airway dimensions and aerosol deposition. A statistical procedure incorporated with the diffusion theory was used to model the dimensional features of the nasal airways which may be responsible for the biological variability in particle deposition. In summary, we have correlated deposition of particles in the size range of 0.004 to 0.15 {mu}m with the nasal dimensions of each subject.

  12. Plant operator performance evaluation based on cognitive process analysis experiment

    International Nuclear Information System (INIS)

    This paper reports on an experiment to clarify plant operators' cognitive processes that has been performed, to improve the man-machine interface which supports their diagnoses and decisions. The cognitive processes under abnormal conditions were evaluated by protocol analyses interviews, etc. in the experiment using a plant training simulator. A cognitive process model is represented by a stochastic network, based on Rasmussen's decision making model. Each node of the network corresponds to an element of the cognitive process, such as observation, interpretation, execution, etc. Some observations were obtained as follows, by comparison of Monte Carlo simulation results with the experiment results: A process to reconfirm the plant parameters after execution of a task and feedback paths from this process to the observation and the task definition of next task were observed. The feedback probability average and standard deviation should be determined for each incident type to explain correctly the individual differences in the cognitive processes. The tendency for the operator's cognitive level to change from skill-based to knowledge-based via rule-based behavior was observed during the feedback process

    International Nuclear Information System (INIS)

    The Risk Assessment Review Group was organized by the U.S. Nuclear Regulatory Commission on July 1, 1977, with four elements to its charter: clarify the achievements and limitations of WASH-1400, the ''Rasmussen Report''; assess the peer comments thereon, and responses to those comments; study the present state of such risk assessment methodology; and recommend to the Commission how (and whether) such methodology can be used in the regulatory and licensing process. Areas of study include: risk assessment methodologies; statistical issues; completeness; the data base; and the WASH-1400 assessment of the damage to human health from radiation after a postulated accident. Specific items discussed include: Browns Ferry; common cause failure; human factors; format and scrutability; the peer review process; earthquakes; risk perception; allegations by UCS concerning WASH-1400 treatment of quality assurance and quality control; current role of probabilistic methods in the regulatory process; acts of violence; ATWS; influence of design defects in quality assurance failures; and calculation of population doses from given releases of radionuclides

    Full Text Available This paper detects structural similarities among several regions in Chile, in particular those that can be compared to the Magellanic and the Chilean Antarctica region: the regions Tarapacá, Libertador Bernardo O’Higgins Riquelme, Bío- Bío and Los Lagos. This exercise is particularly relevant given the economic characteristics and geographic location of all of them. This comparison would allow less advantaged regions to learn from the most successful ones. Policy makers would be able to evaluate ex-ante different policies, helping in this way the decision making process. To this end, in this paper we follow two approaches: first, we find similarities among regions using Le Masne’s (1988 indicator; second, we use one in which the similarities are identified thru the productive links, following the methodologies of Rasmussen (1956, Dietzenbacher and van der Linden (1997 and Soza (2007b. Once we determine which technique is better for our problem, a hierarchical cluster is applied to obtain groups of regions based on the relationship they form. It is of particular interest to identify those sectors that have the largest impact on development and analyze its productive linkages. The analysis is done using the 1996 input-output charts developed by National Institute of Statistics (INE and the Ministry of Planning and Development (MIDEPLAN.

  15. A conceptual framework for intelligent real-time information processing

    Schudy, Robert

    1987-01-01

    By combining artificial intelligence concepts with the human information processing model of Rasmussen, a conceptual framework was developed for real time artificial intelligence systems which provides a foundation for system organization, control and validation. The approach is based on the description of system processing terms of an abstraction hierarchy of states of knowledge. The states of knowledge are organized along one dimension which corresponds to the extent to which the concepts are expressed in terms of the system inouts or in terms of the system response. Thus organized, the useful states form a generally triangular shape with the sensors and effectors forming the lower two vertices and the full evaluated set of courses of action the apex. Within the triangle boundaries are numerous processing paths which shortcut the detailed processing, by connecting incomplete levels of analysis to partially defined responses. Shortcuts at different levels of abstraction include reflexes, sensory motor control, rule based behavior, and satisficing. This approach was used in the design of a real time tactical decision aiding system, and in defining an intelligent aiding system for transport pilots.

    We consider general logarithmic minimal models ${\\cal LM}(p,p')$, with $p,p'$ coprime, on a strip of $N$ columns with the $(r,s)$ Robin boundary conditions introduced by Pearce, Rasmussen and Tipunin. The associated conformal boundary conditions are labelled by the Kac labels $r\\in{\\Bbb Z}$ and $s\\in{\\Bbb N}$. The Robin vacuum boundary condition, labelled by $(r,s\\!-\\!\\frac{1}{2})=(0,\\mbox{$\\textstyle \\frac{1}{2}$})$, is given as a linear combination of Neumann and Dirichlet boundary conditions. The general $(r,s)$ Robin boundary conditions are constructed, using fusion, by acting on the Robin vacuum boundary with an $(r,s)$-type seam consisting of an $r$-type seam of width $w$ columns and an $s$-type seam of width $d=s-1$ columns. The $r$-type seam admits an arbitrary boundary field which we fix to the special value $\\xi=-\\tfrac{\\lambda}{2}$ where $\\lambda=\\frac{(p'-p)\\pi}{2p'}$ is the crossing parameter. The $s$-type boundary introduces $d$ defects into the bulk. We consider the associated quantum Hamiltoni...

    This paper aims to develop a remote sensing method of monitoring grain production in the early stages of crop growth. It is important to oversee the quantity of grain in production at an early stage in order to raise the alarm well in advance if a poor harvest is looming, especially in view of the rapid population increase in Asia and the long-term squeeze on water resources. Grain production monitoring would allow orderly crisis management to maintain food security in Japan, which is far from producing enough grain for its own population. We propose a photosynthesis-based crop production index CPI that takes into account all of: solar radiation, effective air temperature, vegetation biomass, the effect of temperature on photosynthesis by leaves of grain plants, low-temperature sterility, and high-temperature injury. These later factors, which extend the model of Rasmussen, are significant around the heading period of crops. The proposed photosynthesis-based crop production index CPI has accurately predicted the rice yield expressed by the Japanese Crop Situation Index in three years, including the worst yield in recent years, at a test site in Japan.

    Understanding the climate mechanisms requires a precise knowledge of the sequence of events during major climate changes. In order to provide precise relationships between changes in orbital and/or greenhouse gases concentration forcing, sea level changes and high vs low latitudes temperatures, a common chronological framework for different paleoclimatic archives is required. Coherent chronologies for ice cores have been recently produced using a bayesian dating tool, DATICE (Lemieux-Dudon et al., 2010, Bazin et al., 2013, Veres et al., 2013). Such tool has been recently developed to include marine cores and speleothems in addition to ice cores. This new development should enable one to test the coherency of different chronologies using absolute and stratigraphic links as well as to provide relationship between climatic changes recorded in different archives. We present here a first application of multi-archive coherent dating including paleoclimatic archives from (1) Greenland (NGRIP ice core), (2) Mediterranean sea (marine core MD90-917, 41° N17° E, 1010 m) and (3) speleothems from the South of France and North Tunisia (Chauvet, Villars and La Mine speleothems, Genty et al., 2006). Thanks to the good absolute chronological constraints from annual layer counting in NGRIP, 14C and tephra layers in MD90-917 and U-Th dating in speleothems, we can provide a precise chronological framework for the last 50 ka (ie. thousand years before present). Then, we present different tests on how to combine the records from the different archives and give the most plausible scenario for the sequence of events at different latitudes over the last deglaciation.

    Fluvial sediment, a vital surface water resource, is hazardous in excess. Suspended sediment, the most prevalent source of impairment of river systems, can adversely affect flood control, navigation, fisheries and aquatic ecosystems, recreation, and water supply (e.g., Rasmussen et al., 2009; Qu, 2014). Monitoring programs typically focus on suspended-sediment concentration (SSC) and discharge (SSQ). These time-series data are used to study changes to basin hydrology, geomorphology, and ecology caused by disturbances. The U.S. Geological Survey (USGS) has traditionally used physical sediment sample-based methods (Edwards and Glysson, 1999; Nolan et al., 2005; Gray et al., 2008) to compute SSC and SSQ from continuous streamflow data using a sediment transport-curve (e.g., Walling, 1977) or hydrologic interpretation (Porterfield, 1972). Accuracy of these data is typically constrained by the resources required to collect and analyze intermittent physical samples. Quantifying SSC using continuous instream turbidity is rapidly becoming common practice among sediment monitoring programs. Estimations of SSC and SSQ are modeled from linear regression analysis of concurrent turbidity and physical samples. Sediment-surrogate technologies such as turbidity promise near real-time information, increased accuracy, and reduced cost compared to traditional physical sample-based methods (Walling, 1977; Uhrich and Bragg, 2003; Gray and Gartner, 2009; Rasmussen et al., 2009; Landers et al., 2012; Landers and Sturm, 2013; Uhrich et al., 2014). Statistical comparisons among SSQ computation methods show that turbidity-SSC regression models can have much less uncertainty than streamflow-based sediment transport-curves or hydrologic interpretation (Walling, 1977; Lewis, 1996; Glysson et al., 2001; Lee et al., 2008). However, computation of SSC and SSQ records from continuous instream turbidity data is not without challenges; some of these include environmental fouling, calibration, and

    In the past the transition between an unconformable surface in the south to a conformable horizon towards the north has made identification and mapping the base-Quaternary in the central North Sea difficult (Sejrup et al 1991; Gatliff et al 1994). However recent integration of biostratigraphy, pollen analysis, paleomagnetism and amino acid analysis in the Dutch and Danish sectors (Rasmussen et al 2005; Kuhlmann et al 2006) has allowed greater confidence in the correlation to the region 3D seismic datasets and thus has allowed the base-Quaternary to be mapped across the entire basin. The base-Quaternary has been mapped using the PGS MegaSurvey dataset from wells in the Danish Sector along the initially unconformable horizon and down the delta front into the more conformable basin giving a high degree of confidence in the horizon pick. The revised base-Quaternary surface reaches a depth of 1248 ms TWT with an elongate basin shape which is significantly deeper than the traditionally mapped surface. Using RMS amplitudes and other seismic attributes the revised base-Quaternary has been investigated along the horizon and in time slice to interpret the environments of the earliest Quaternary prior to the onset of glaciation. Combined with analysis of aligned elongate furrows over 10 km long, 100 m wide and 100 m deep suggest a deep marine environment in an almost enclosed basin with persistent strong NW-SE bottom currents in the deepest parts. Pockmarks were formed by the escape of shallow gas on the sides of a small delta in the eastern part of the basin. The progradation of large deltas from both the north and south into the basin make up the majority of the deposition of sediment into the basin.

    The identification and mapping of the base-Quaternary boundary in the central parts of the North Sea is problematic due to the change from an unconformable transition between Pliocene and Pleistocene deltaic deposits in the southern North Sea to a conformable one further north (Sejrup et al 1991; Gatliff et al 1994). The best estimates of the transition use seismic reflection data to identify a 'crenulated reflector' (Buckley 2012), or rely on correlating sparse biostratigraphy (Cameron et al 1987). Recent integration of biostratigraphy, pollen analysis, paleomagnetism and amino acid analysis in the Dutch and Danish sectors (Rasmussen et al 2005; Kuhlmann et al 2006) allows greater confidence in the correlation to a regional 3D seismic dataset and show that the base-Quaternary can be mapped across the entire basin. The base-Quaternary has been mapped using the PGS MegaSurvey dataset from wells in the Danish Sector along the initially unconformable horizon and down the delta front into the more conformable basin giving a high degree of confidence in the horizon pick. The mapped horizon is presented here alongside the difference between this new interpretation and the previously interpreted base-Quaternary (Buckley 2012). The revised base-Quaternary surface reaches a depth of 1248 ms TWT or approximately 1120 m (assuming average velocity of 1800 m/s) showing an elongate basin shape that follows the underlying structure of the Central Graben. The difference between the revised base-Quaternary and the traditional base-Quaternary reaches a maximum of over 600 ms TWT or approximately 540 m in the south-west with over 300 ms TWT or approximately 270 m at the Josephine well (56° 36.11'N, 2° 27.09'E) in the centre of the basin. Mapping this new base-Quaternary allows for the interpretation of the paleo-envionrment during the earliest Quaternary. Seismic attribute analysis indicates a deep water basin with sediment deposition from multiple deltas and redistribution by deep

    A prototype version of a computer simulation system named JACOS (JAeri COgnitive Simulation system) has been developed at JAERI (Japan Atomic Energy Research Institute) to simulate the man-machine system behavior in which both the cognitive behavior of a human operator and the plant behavior affect each other. The objectives of this system development is to provide man-machine system analysts with detailed information on the cognitive process of an operator and the plant behavior affected by operator's actions in accidental situations of an NPP (nuclear power plant). The simulation system consists of an operator model and a plant model which are coupled dynamically. The operator model simulates an operator's cognitive behavior in accidental situations based on the decision ladder model of Rasmussen, and is implemented using the AI-techniques of the distributed cooperative inference method with the so-called blackboard architecture. Rule-based behavior is simulated using knowledge representation with If-Then type of rules. Knowledge-based behavior is simulated using knowledge representation with MFM (Multilevel Flow Modeling) and qualitative reasoning method. Cognitive characteristics of attentional narrowing, limitation of short-term memory, and knowledge recalling from long-term memory are also modeled. The plant model of a 3-loop PWR is also developed using a best estimate thermal-hydraulic analysis code RELAP5/MOD2. Some simulations of incidents were performed to verify the human model. It was found that AI-techniques used in the human model are suitable to simulate the operator's cognitive behavior in an NPP accident. The models of cognitive characteristics were investigated in the effects on simulated results of cognitive behaviors. (author)

    Jacob Chandy, who passed away in 2007 at the age of 97, was born into a deeply religious Christian family in Kerala, South India. After obtaining his medical education at the Madras Medical College, Madras, he serendipitously came to work with Dr Paul Harrison, a renowned medical missionary, in the Gulf state of Bahrain. Harrison urged Chandy to pursue training in the fledgling specialty of neurosurgery in North America. Chandy received his neurosurgical training at the Montreal Neurological Institute with Wilder Penfield and in Chicago with Theodore Rasmussen. At Harrison's urging, Chandy decided to return to India after completing his training to work at the Christian Medical College in Vellore. Thus, it was in 1949 that Chandy established the first neurosurgery department in south Asia in Vellore. He initiated the first neurosurgical training program in India at the Christian Medical College in 1957, with a distinct North American neurosurgical tradition. He went on to train nearly 20 neurosurgeons, many of whom set up new departments of neurosurgery in their home states. Chandy also had several other remarkable achievements to his credit. Despite the pressures of clinical practice, he insisted on fostering both basic and clinical neurosciences within his department, an arrangement that persists to this day in the Department of Neurological Sciences at the Christian Medical College, Vellore. As the Principal (Dean) of the Christian Medical College, Chandy displayed his skills as a medical educator and administrator. In this role, he was instrumental in starting specialty training programs in several other medical and surgical disciplines. His greatest legacies survive in the form of the department that he founded and his trainees and their students who have helped to establish neurosurgery all over the country. PMID:20647965

    Stalagmite GAR-01 preserves a continuous, high-resolution record of climate in northern Spain over the past 14,000 years. High resolution (i.e., biennially- to decadally-resolved) laser isotope data reveal both high and low frequency climatic variability through the Holocene including a prominent carbon isotope anomaly centred on 4,000 yrs BP. Most striking is the GAR-01 pre-Holocene record that includes a pronounced excursion to cold and dry conditions at the time of the Younger Dryas Event. According to the well-defined carbon isotope excursion and six U-Series dates across the anomaly, stalagmite GAR-01 records the Younger Dryas in northern Spain between 12,907 ± 77 to 11,653 ± 116 yrs BP, in excellent agreement with the latest NGRIP Younger Dryas chronology (i.e., 12,846 ± 138 to 11,653 ± 99 yrs BP; Rasmussen et al., 2006). The GAR-01 Younger Dryas oxygen (a 1.8 per mil negative excursion) and carbon (a 3.4 per mil positive excursion) isotope anomalies are muted relative to higher latitude proxy records but the uninterrupted growth during the Younger Dryas at an average rate of 37 microns/year combined with in situ laser isotope and trace element techniques permits a detailed reconstruction of the last stages of deglaciation. The GAR-01 biennial-scale isotope and subannual-scale trace element record of the Younger Dryas Event provides crucial information about the mechanisms that led to the onset, stabilisation, and termination of this important abrupt climate change event. Striking similarities between the GAR-01 14,000 year carbon isotope record and the coeval Cariaco Basin Ti and Fe (%) records suggests that northern Iberia may be an important location for understanding North Atlantic tropical-extratropical teleconnections.

    Full Text Available BACKGROUND: The fractures of proximal tibia present complex problems for the treating surgeon. They are usually high velocity injuries and are associated with extensive soft tissue injuries apart from comminuted fractures. The main cause for these high energy injurie s is RTA and fall from height also contributes to these injuries. In our study we chose to fix these complex fractures with the versatile Ilizarov apparatus. The results are quite gratifying and the complications are few. MATERIALS & METHODS : In our series we have included 12 patients who are treated with Ilizarov apparatus during the period Feb 2009 to June 2010, in Gandhi Hospital, a tertiary care hospital attached to Gandhi Medical College, Secunderabad. Out of these patients 11 are male and 1 female, an d the age of the patients varied from 25 - 56, the commonest cause of these fractures in our series is RTA (11 out of 12 patients. Most of our patients are of Schaztker’s type IV. RESULTS: The patients are evaluated using Knee Society Scoring system, Functi onal evaluation system and Rasmussen radiological criteria. Out of12 patients, 11 had excellent knee score and functional results. 1 patient had a fair knee score and poor functional results. CONCLUSIONS: TheIlizarov method in fixing the proximal tibial fr actures which are often comminuted and are associated with extensive soft tissue injury scores over other types of fixation. The fractures united readily and the complications like infection and joint stiffness are less comparatively in this method. Our re sults are comparable to other studies in this regard.

  10. Vapor characterization of Tank 241-C-103

    International Nuclear Information System (INIS)

    The Westinghouse Hanford Company Tank Vapor Issue Resolution Program has developed, in cooperation with Northwest Instrument Systems, Inc., Oak Ridge National Laboratory, Oregon Graduate Institute of Science and Technology, Pacific Northwest Laboratory, and Sandia National Laboratory, the equipment and expertise to characterize gases and vapors in the high-level radioactive waste storage tanks at the Hanford Site in south central Washington State. This capability has been demonstrated by the characterization of the tank 241-C-103 headspace. This tank headspace is the first, and for many reasons is expected to be the most problematic, that will be characterized (Osborne 1992). Results from the most recent and comprehensive sampling event, sample job 7B, are presented for the purpose of providing scientific bases for resolution of vapor issues associated with tank 241-C-103. This report is based on the work of Clauss et al. 1994, Jenkins et al. 1994, Ligotke et al. 1994, Mahon et al. 1994, and Rasmussen and Einfeld 1994. No attempt has been made in this report to evaluate the implications of the data presented, such as the potential impact of headspace gases and vapors to tank farm workers health. That and other issues will be addressed elsewhere. Key to the resolution of worker health issues is the quantitation of compounds of toxicological concern. The Toxicology Review Panel, a panel of Pacific Northwest Laboratory experts in various areas, of toxicology, has chosen 19 previously identified compounds as being of potential toxicological concern. During sample job 7B, the sampling and analytical methodology was validated for this preliminary list of compounds of toxicological concern. Validation was performed according to guidance provided by the Tank Vapor Conference Committee, a group of analytical chemists from academic institutions and national laboratories assembled and commissioned by the Tank Vapor Issue Resolution Program

    The use of pneumatically generated pressure signals for aquifer characterization Hydraulic tests are the most reliable method of obtaining estimates of hydrologic properties, such as conductivity, that are essential for flow and transport modeling. The use of a sinusoidal signal for hydraulic testing is well established, with Streltsova (1988), Rasmussen (2003) and others having developed analytic solutions. Sinusoidal tests provide a unique easily distinguished signal that reduces ambiguity during analysis and we show that a sinusoidal pressure signal propagates farther into the formation than a standard slug-test signal. If a sinusoidal test is combined with a slug and/or a constant rate test, it can further reduce uncertainty in the estimated parameter values. We demonstrate how pneumatic pressure can be used to generate all three of these signals. By positioning pressure transducers both below the water level and in the head space above the water, we can monitor the total pressure acting on the formation and the changes in water level. From the changes in water level, it is possible to calculate the flow rate in and out of the well, assuming that the well diameter and water density are known. Using gas flow controllers with a Supervisory Control And Data Acquisition (SCADA) system we are able to precisely control the pressures in the well. The use of pneumatic pressure has the advantage that it requires less equipment (no pumps) and produces no water. We also show how the numerical well test analysis program nSIGHTS can be used to analyze all three types of tests simultaneously and to assess the relative contribution of each type of test to the parameter estimation. nSIGHTS was recently released as open source by Sandia National Laboratories and is available for free.

    The overall aim of the project was to gain more knowledge about the kinetics of gas hydrate formation especially the early growth phase. Knowledge of kinetics of gas hydrate formation is important and measurements of gas hydrate particle size and concentration can contribute to improve this knowledge. An experimental setup for carrying out experimental studies of the nucleation and growth of gas hydrates has been constructed and tested. Multi wavelength extinction (MWE) was the experimental technique selected for obtaining particle diameter and concentration. The principle behind MWE is described as well as turbidity spectrum analysis that in an initial stage of the project was considered as an alternative experimental technique. Details of the experimental setup and its operation are outlined. The measuring cell consists of a 1 litre horizontal tube sustaining pressures up to 200 bar. Laser light for particle size determination can be applied through sapphire windows. A description of the various auxiliary equipment and of another gas hydrate cell used in the study are given. A computer program for simulation and analysis of gas hydrate experiments is based on the gas hydrate kinetics model proposed by Skovborg and Rasmussen (1993). Initial measurements showed that knowledge of the refractive index of gas hydrates was important in order to use MWE. An experimental determination of the refractive index of methane and natural gas hydrate is described. The test experiments performed with MWE on collectives of gas hydrate particles and experiments with ethane, methane and natural gas hydrate are discussed. Gas hydrate particles initially seem to grow mainly in size and at latter stages in number. (EG) EFP-94; 41 refs.

  14. Waste Feed Delivery System Phase 1 Preliminary RAM Analysis

    International Nuclear Information System (INIS)

    This report presents the updated results of the preliminary reliability, availability, and maintainability (RAM) analysis of selected waste feed delivery (WFD) operations to be performed by the Tank Farm Contractor (TFC) during Phase I activities in support of the Waste Treatment and Immobilization Plant (WTP). For planning purposes, waste feed tanks are being divided into five classes in accordance with the type of waste in each tank and the activities required to retrieve, qualify, and transfer waste feed. This report reflects the baseline design and operating concept, as of the beginning of Fiscal Year 2000, for the delivery of feed from three of these classes, represented by source tanks 241-AN-102, 241-AZ-101 and 241-AN-105. The preliminary RAM analysis quantifies the potential schedule delay associated with operations and maintenance (OBM) field activities needed to accomplish these operations. The RAM analysis is preliminary because the system design, process definition, and activity planning are in a state of evolution. The results are being used to support the continuing development of an O and M Concept tailored to the unique requirements of the WFD Program, which is being documented in various volumes of the Waste Feed Delivery Technical Basis (Carlson. 1999, Rasmussen 1999, and Orme 2000). The waste feed provided to the WTP must: (1) meet limits for chemical and radioactive constituents based on pre-established compositional envelopes (i.e., feed quality); (2) be in acceptable quantities within a prescribed sequence to meet feed quantities; and (3) meet schedule requirements (i.e., feed timing). In the absence of new criteria related to acceptable schedule performance due to the termination of the TWRS Privatization Contract, the original criteria from the Tank Waste Remediation System (77443s) Privatization Contract (DOE 1998) will continue to be used for this analysis

  15. Some wind and instability parameters associated with strong and violent tornadoes: 2. Variations in the combinations of wind and instability parameters

    Science.gov (United States)

    Johns, Robert H.; Davies, Jonathan M.; Leftwich, Preston W.

    Meteorologists have long known that both potential buoyant energy and the strength and vertical profile of the tropospheric wind fields are important in the process of tornado development [e.g., Miller, 1972]. Further, operational experience suggests that the combinations of wind parameters and instability parameters vary considerably from one tornado situation to another. Numerical models suggest that the type of storm that develops in a given situation (e.g., an isolated supercell) is related to both the vertical wind profile and the potential buoyant energy of the air in the updraft entrainment layer [Weisman and Klemp, 1982, 1986]. Observational studies by Rasmussen and Wilhelmson [1983] and Leftwich and Wu [1988] have examined the wind shear/potential buoyant energy relationship in association with tornado development. These studies involved limited data sets and were concerned with the wind shear in a relatively deep layer of the troposphere (0-4-km above ground level (AGL)). Recently, interest has focused on the nature of the wind fields in shallower layers of the lower troposphere, layers that more nearly correspond to the updraft entrainment region [Davies, 1989; Davies-Jones et al., 1990]. Utilizing a large comprehensive data set, Johns et al [1990] (hereafter referred to as JDL) examined the relationship between 0-2-km AGL "positive" wind shear (PWS) and convective available potential energy (CAPE) [Moncrieff and Green, 1972] in association with strong and violent tornado development. In this paper (part 2) the authors review the initial work of JDL and examine additional wind and potential buoyant energy parameter relationships associated with the data set compiled by JDL.

  16. Using the decision ladder to understand road user decision making at actively controlled rail level crossings.

    Rail level crossings (RLXs) represent a key strategic risk for railways worldwide. Despite enforcement and engineering countermeasures, user behaviour at RLXs can often confound expectations and erode safety. Research in this area is limited by a relative absence of insights into actual decision making processes and a focus on only a subset of road user types. One-hundred and sixty-six road users (drivers, motorcyclists, cyclists and pedestrians) completed a diary entry for each of 457 naturalistic encounters with RLXs when a train was approaching. The final eligible sample comprised 94 participants and 248 encounters at actively controlled crossings where a violation of the active warnings was possible. The diary incorporated Critical Decision Method probe questions, which enabled user responses to be mapped onto Rasmussen's decision ladder. Twelve percent of crossing events were non-compliant. The underlying decision making was compared to compliant events and a reference decision model to reveal important differences in the structure and type of decision making within and between road user groups. The findings show that engineering countermeasures intended to improve decision making (e.g. flashing lights), may have the opposite effect for some users because the system permits a high level of flexibility for circumvention. Non-motorised users were more likely to access information outside of the warning signals because of their ability to achieve greater proximity to the train tracks and the train itself. The major conundrum in resolving these issues is whether to restrict the amount of time and information available to users so that it cannot be used for circumventing the system or provide more information to help users make safe decisions.

    Full Text Available Targeting pro-inflammatory events to reduce seizures is gaining momentum. Experimentally, antagonism of inflammatory processes and of blood-brain barrier (BBB damage has been demonstrated to be beneficial in reducing status epilepticus (SE. Clinically, a role of inflammation in the pathophysiology of drug resistant epilepsies is suspected. However, the use anti-inflammatory drug such as glucocorticosteroids (GCs is limited to selected pediatric epileptic syndromes and spasms. Lack of animal data may be one of the reasons for the limited use of GCs in epilepsy. We evaluated the effect of the CG dexamethasone in reducing the onset and the severity of pilocarpine SE in rats. We assessed BBB integrity by measuring serum S100β and Evans Blue brain extravasation. Electrophysiological monitoring and hematologic measurements (WBCs and IL-1β were performed. We reviewed the effect of add on dexamethasone treatment on a population of pediatric patients affected by drug resistant epilepsy. We excluded subjects affected by West, Landau-Kleffner or Lennox-Gastaut syndromes and Rasmussen encephalitis, known to respond to GCs or adrenocorticotropic hormone (ACTH. The effect of two additional GCs, methylprednisolone and hydrocortisone, was also reviewed in this population. When dexamethasone treatment preceded exposure to the convulsive agent pilocarpine, the number of rats developing status epilepticus (SE was reduced. When SE developed, the time-to-onset was significantly delayed compared to pilocarpine alone and mortality associated with pilocarpine-SE was abolished. Dexamethasone significantly protected the BBB from damage. The clinical study included pediatric drug resistant epileptic subjects receiving add on GC treatments. Decreased seizure frequency (≥ 50% or interruption of status epilepticus was observed in the majority of the subjects, regardless of the underlying pathology. Our experimental results point to a seizure-reducing effect of

  18. Fifty Years of THERP and Human Reliability Analysis

    2012-06-01

    In 1962 at a Human Factors Society symposium, Alan Swain presented a paper introducing a Technique for Human Error Rate Prediction (THERP). This was followed in 1963 by a Sandia Laboratories monograph outlining basic human error quantification using THERP and, in 1964, by a special journal edition of Human Factors on quantification of human performance. Throughout the 1960s, Swain and his colleagues focused on collecting human performance data for the Sandia Human Error Rate Bank (SHERB), primarily in connection with supporting the reliability of nuclear weapons assembly in the US. In 1969, Swain met with Jens Rasmussen of Risø National Laboratory and discussed the applicability of THERP to nuclear power applications. By 1975, in WASH-1400, Swain had articulated the use of THERP for nuclear power applications, and the approach was finalized in the watershed publication of the NUREG/CR-1278 in 1983. THERP is now 50 years old, and remains the most well known and most widely used HRA method. In this paper, the author discusses the history of THERP, based on published reports and personal communication and interviews with Swain. The author also outlines the significance of THERP. The foundations of human reliability analysis are found in THERP: human failure events, task analysis, performance shaping factors, human error probabilities, dependence, event trees, recovery, and pre- and post-initiating events were all introduced in THERP. While THERP is not without its detractors, and it is showing signs of its age in the face of newer technological applications, the longevity of THERP is a testament of its tremendous significance. THERP started the field of human reliability analysis. This paper concludes with a discussion of THERP in the context of newer methods, which can be seen as extensions of or departures from Swain’s pioneering work.

    We consider general logarithmic minimal models LM≤ft( p,{{p}\\prime}\\right) , with p,{{p}\\prime} coprime, on a strip of N columns with the (r, s) Robin boundary conditions introduced by Pearce, Rasmussen and Tipunin. On the lattice, these models are Yang–Baxter integrable loop models that are described algebraically by the one-boundary Temperley–Lieb algebra. The (r, s) Robin boundary conditions are a class of integrable boundary conditions satisfying the boundary Yang–Baxter equations which allow loop segments to either reflect or terminate on the boundary. The associated conformal boundary conditions are organized into infinitely extended Kac tables labelled by the Kac labels r\\in {Z} and s\\in {N} . The Robin vacuum boundary condition, labelled by ≤ft(r,s-\\frac{1}{2}\\right)=≤ft(0,\\frac{1}{2}\\right) , is given as a linear combination of Neumann and Dirichlet boundary conditions. The general (r, s) Robin boundary conditions are constructed, using fusion, by acting on the Robin vacuum boundary with an (r, s)-type seam consisting of an r-type seam of width w columns and an s-type seam of width d  =  s  ‑  1 columns. The r-type seam admits an arbitrary boundary field which we fix to the special value ξ =-\\fracλ{2} where λ =\\frac≤ft( {{p}\\prime}-p\\right)π{{{p}\\prime}} is the crossing parameter. The s-type boundary introduces d defects into the bulk. We consider the commuting double-row transfer matrices and their associated quantum Hamiltonians and calculate analytically the boundary free energies of the (r, s) Robin boundary conditions. Using finite-size corrections and sequence extrapolation out to system sizes N+w+d≤slant 26 , the conformal spectrum of boundary operators is accessible by numerical diagonalization of the Hamiltonians. Fixing the parity of N for r\

    With this study we investigated the role of nonsteroidal anti-inflammatory drugs (NSAIDs) in human skeletal muscle regeneration. Young men ingested NSAID [1200 mg/d ibuprofen (IBU)] or placebo (PLA) daily for 2 wk before and 4 wk after an electrical stimulation-induced injury to the leg extensor muscles of one leg. Muscle biopsies were collected from the vastus lateralis muscles before and after stimulation (2.5 h and 2, 7, and 30 d) and were assessed for satellite cells and regeneration by immunohistochemistry and real-time RT-PCR, and we also measured telomere length. After injury, and compared with PLA, IBU was found to augment the proportion of ActiveNotch1(+) satellite cells at 2 d [IBU, 29 ± 3% vs. PLA, 19 ± 2% (means ± sem)], satellite cell content at 7 d [IBU, 0.16 ± 0.01 vs. PLA, 0.12 ± 0.01 (Pax7(+) cells/fiber)], and to expedite muscle repair at 30 d. The PLA group displayed a greater proportion of embryonic myosin(+) fibers and a residual ∼2-fold increase in mRNA levels of matrix proteins (all P muscle remodeling during large-scale regeneration of injured human skeletal muscle.-Mackey, A.

    In addition to volcanic and tectonic activity on the border of the Late Pleistocene and Holocene occurred and other disastrous events that are reflected in the history of the lakes. The recognition of meteorite impact crater lakes is impeded by difficulties in finding evidence of an impact origin. Such lakes have been recognized (Hartung and Koeberl, 1994) by their circular shape, their occurrence outside of areas where other mechanisms for circular depression formation are readily apparent, and the preservation of meteorite or ejected glass fragments (Cohen. 2003). Meteorite impact Lake appeared not only in early periods (like Lake El'gygytgyn and Lake Yanisyarvi in Russia), but in the Late Pleistocene and Holocene as well. One of these lakes is located in the Nizhny Novgorod region of Russia. Svetloyar (56º49' N; 45º05'E; 109 m a.s.l.) - lake with a small area of 0.15 km2 and a great depth of the lake up to 35 m., a circular shape, surrounded on three sides by hills , reaching 15 m above the lake level. On the lake we have carried out paleolimnological and hydrological investigations.Interdisciplinary researches included sedimentological, geochemical, pollen, diatom, radiocarbon and other analyses of lake sediments. Based on field measurements, we created a digital morphometric model of the bottom depths and slopes of the lake. Using the all results we are reconstruct the Lake's history and climatic changes. We establish a long hiatus after the disappearance of large lake on the border of the late Pleistocene and Holocene. For comparison we were have studied three of the morphometric similar lakes in the Nizhny Novgorod region. According to preliminary data the history of any of these lakes is not similar the Lake Svetloyar history. We discuss our results and have compared with data on the meteorite Lake Kaali , Estonia (Rasmussen et al., 2000; Raukas et.al,1995; 2002; Veski et.al, 2001, 2002, 2004).

  5. Simulation and experimental studies of operators' decision styles and crew composition while using an ecological and traditional user interface for the control room of a nuclear power plant

    International Nuclear Information System (INIS)

    A traditional human factors (i.e., microergonomic) approach to complex human-machine systems is only concerned with improving the workstation (user interface) design. This approach, by ignoring the importance of the integration of the user interface with job and organizational design, results in systems which lead, at best, only to sub-optimization and are therefore inherently error- and failure-prone. Such systems, when eventually faced with the concentration of certain fault events, will suffer from this open-quotes resident pathogenclose quotes and, as such, are doomed to failure. Also, when complex technological systems, such as nuclear power plants, move from routine to non-routine (normal to emergency) operation, the controlling operators need to dynamically match the system's new requirements. This mandates integrated and harmonious changes in information presentation (display), changes in (job) performance requirements in part because of operators' inevitable involuntary transition to different levels of cognitive control, and reconfigurations of the operators' team (organizational) structure and communication. It is also demonstrated that the skill, rule, and knowledge (SRK) model, developed by Rasmussen, is a high-potential and powerful framework that could be utilized for the proposed integration purpose. The objective of this research was threefold: (1) using the SRK model, to develop an integrated information processing conceptual framework (for integration of workstation, job, and team design); (2) to evaluate the user interface component of this framework -- the ecological display; and (3) to analyze the effect of operators' individual information processing behavior and decision styles on handling plant disturbances, on their performance and preference for traditional and ecological user interfaces

  6. Bayesian multivariate linear regression with application to change point models in hydrometeorological variables

    Multivariate linear regression is one of the most popular modeling tools in hydrology and climate sciences for explaining the link between key variables. Piecewise linear regression is not always appropriate since the relationship may experiment sudden changes due to climatic, environmental, or anthropogenic perturbations. To address this issue, a practical and general approach to the Bayesian analysis of the multivariate regression model is presented. The approach allows simultaneous single change point detection in a multivariate sample and can account for missing data in the response variables and/or in the explicative variables. It also improves on recently published change point detection methodologies by allowing a more flexible and thus more realistic prior specification for the existence of a change and the date of change as well as for the regression parameters. The estimation of all unknown parameters is achieved by Monte Carlo Markov chain simulations. It is shown that the developed approach is able to reproduce the results of Rasmussen (2001) as well as those of Perreault et al. (2000a, 2000b). Furthermore, two of the examples provided in the paper show that the proposed methodology can readily be applied to some problems that cannot be addressed by any of the above-mentioned approaches because of limiting model structure and/or restrictive prior assumptions. The first of these examples deals with single change point detection in the multivariate linear relationship between mean basin-scale precipitation at different periods of the year and the summer-autumn flood peaks of the Broadback River located in northern Quebec, Canada. The second one addresses the problem of missing data estimation with uncertainty assessment in multisite streamflow records with a possible simultaneous shift in mean streamflow values that occurred at an unknown date.

  7. Prevention of insufficient team monitoring among nuclear power plant operators

    International Nuclear Information System (INIS)

    Earlier studies showed that the most common human errors involving operators at overseas nuclear power plants were those due to insufficient team monitoring, namely errors subsequently committed by superiors or fellow workers rather than an initial error committed by an operator. Although cases of insufficient team monitoring have rarely been reported in Japan, such faults could occur judging from the results of simulator training for operators. We therefore examined possible solutions to this problem. Using Rasmussen's model of human behavior, we analyzed the cases of insufficient team monitoring identified by instructors based on their experience in training. Analyses revealed that errors occur when an operator as a member of a team has gained a wrong situation awareness and this wrong situation awareness has not been corrected in the subsequent team action. The cases of insufficient team monitoring that were found during training can be classified into five types: the intuition type, the labyrinth type, the underestimation type, the dependence-on-experienced-operators type, and the complacency type. Problems identified in these five types of insufficient team monitoring have been analyzed using a newly developed team monitoring behavior model. Common factors that have been identified as the causes of errors committed during busy hours such as an emergency are: (1) the procedures are difficult to use; (2) necessary information cannot be retrieved easily; and (3) the procedure places as undue burden on a shift supervisor. These factors must be improved. Accordingly, we propose adopting a set of remedial measures: (1) the preparation of an easy-to-use procedure that sets forth instructions to be given by a shift supervisor; (2) the preparation of educational materials that are effective in assessing the progress of an event and gaining a broad overview of the situation; and (3) the sharing of responsibility and the delegation of authority to alleviate the burden on

Non-stimulant drugs have also been reported successful. However, many controlled studies exclude patients with comorbidities typical for patients seen in clinical setting. Many patients are also considered non-responders to medication. Current knowledge might not be directly useful to clinicians. The present article reviews the literature on pharmacological and psychotherapeutic treatment in adult ADHD emphasizing comorbidity and other clinically important factors, as well as ADHD specific outcomes. Thirty-three relevant studies of pharmacotherapy and three studies of psychotherapy were included. Most subjects had little current comorbidity, but some studies included subjects with substance use disorder. Significant effect of treatment on ADHD symptoms was found in most studies using pharmacotherapy and all studies of psychotherapy. Both positive and negative effects on comorbid anxiety and depression measures were reported. Pharmacotherapy did not seem to have effect on substance use disorder. Few pharmacotherapy studies conducted any long-term follow-up; two studies that did, found that most subjects had discontinued medication. A clear-cut dose-respons relationship was not substanciated. In conclusion, clinicians have good support for both pharmacological and psychotherapeutic treatment of ADHD in adults, but should take additional measures to deal with comorbidities as well as treatment adherence.Keywords: ADHD, adults, treatment, stimulants, psychotherapy, comorbidity

    On September 9, 1992, the US Environmental Protection Agency (EPA) issued General Permit No. WA-R-00-OOOF, Authorization to Discharge Under the National Pollutant Discharge Elimination System (NPDES) for Storm Water Discharges Associated with Industrial Activity to the US Department of Energy, Richland Operations Office (RL). RL submitted a Notice of Intent to comply with this permit to EPA in conformance with the General Permit requirements on October 1, 1992. On February 14, 1994, EPA issued a Storm Water General Permit Coverage Notice and assigned WA-R-00-Al7F as the Hanford Site`s National Pollutant Discharge Elimination System (NPDES) storm water permit number. The Hanford Site Storm Water Pollution Prevention Plan (SWPPP) (WHC 1996a) was certified by J. E Rasmussen, Director Environmental Assurance, RL, on September 24, 1996, in compliance with Part IV.B(i) of the General Permit. As required by General Permit No. WA-R-00-OOOF (WA-R-00-Al7F), Section IV, Part D, Section 4.c, an annual report must be developed by RL and retained on site to verify that the requirements listed in the General Permit are being implemented. The previous Hanford Site Storm Plater Comprehensive Site Compliance Evaluation Report (WHC 1996b) addressed the period from July 1995 through June 1996. This document fulfills the requirement to prepare an annual report and contains the results of inspections of the storm water outfalls listed in the SWPPP (WHC 1996a). This report also describes the methods used to conduct the 1100 Storm Plater Comprehensive Site Compliance Evaluation (SWCSCE) as required in Part IV, Section D.4.c in the General Permit; summarizes the results of the compliance evaluation; and documents significant leaks and spills. The reporting year for this SWCSCE report is July 1, 1996 through June 30, 1997.

  10. Evaluating turbidity and suspended-sediment concentration relations from the North Fork Toutle River basin near Mount St. Helens, Washington; annual, seasonal, event, and particle size variations - a preliminary analysis.

    Regression of in-stream turbidity with concurrent sample-based suspended-sediment concentration (SSC) has become an accepted method for producing unit-value time series of inferred SSC (Rasmussen et al., 2009). Turbidity-SSC regression models are increasingly used to generate suspended-sediment records for Pacific Northwest rivers (e.g., Curran et al., 2014; Schenk and Bragg, 2014; Uhrich and Bragg, 2003). Recent work developing turbidity-SSC models for the North Fork Toutle River in Southwest Washington (Uhrich et al., 2014), as well as other studies (Landers and Sturm, 2013, Merten et al., 2014), suggests that models derived from annual or greater datasets may not adequately reflect shorter term changes in turbidity-SSC relations, warranting closer inspection of such relations. In-stream turbidity measurements and suspended-sediment samples have been collected from the North Fork Toutle River since 2010. The study site, U.S. Geological Survey (USGS) streamgage 14240525 near Kid Valley, Washington, is 13 river km downstream of the debris avalanche emplaced by the 1980 eruption of Mount St. Helens (Lipman and Mullineaux, 1981), and 2 river km downstream of the large sediment retention structure (SRS) built from 1987–1989 to mitigate the associated sediment hazard. The debris avalanche extends roughly 25 km down valley from the edifice of the volcano and is the primary source of suspended sediment moving past the streamgage (NF Toutle-SRS). Other significant sources are debris flow events and sand deposits upstream of the SRS, which are periodically remobilized and transported downstream. Also, finer material often is derived from the clay-rich original debris avalanche deposit, while coarser material can derive from areas such as fluvially reworked terraces.

    BACKGROUND:There are many internal fixation methods for tibial plateau fractures with their own merit and demerit. Knee joint internal fixation for Schatzker type V and VI bicondylar tibial plateau fractures has better outcomes, but it is unclear about the specific difference in the repair of these two kinds of fractures. OBJECTIVE: To observe the repair effects of metal implants insertedviaanterolateral and posteromedial knee joint approach on Schatzker type V and VI bicondylar tibial plateau fractures. METHODS: From January 2009 to December 2012, 67 patients with Schatzker type V and VI bicondylar tibial plateau fractures were admitted at the Department of Orthopedics, Beijing Changping Hospital, China, including 38 cases of Schatzker type V and 29 cases of Schatzker type VI. Al these patients underwent internal fixation with metal implantsvia the anterolateral and posteromedial knee joint approaches. During the folow-up, differences in fracture healing and functional recovery between the two groups were observed. RESULTS AND CONCLUSION: The wounds of al patients after active treatment were healed. By the last folow-up, Schatzker VI patients had better outcomes than Schatzker V patients in the aspects of varus-valgus scores, Rasmussen radiology scores, flexion and extension scores, joint range of motion, joint stability scores and good rate of knee joint function (P 0.05). Schatzker V patients showed better recovery of the articular surface and reliable internal fixation. These findings indicate that the internal fixation viathe anterolateral and posteromedial knee joint approaches has better clinical efficacy in the treatment of Schatzker type V bicondylar tibial plateau fractures than Schatzker type VI bicondylar tibial plateau fractures.%背景:胫骨平台骨折治疗的内固定修复方法有很多种,各有优缺点,有研究报道膝关节内固定修复SchatzkerⅤ、Ⅵ型胫骨平台双髁骨折效果较好,具体此2种骨折修复

    International Nuclear Information System (INIS)

    difficult problems which have not yet been investigated in extending the proposed approach to fault management. In the present research Rasmussen et al's framework was used for designing computer-generated graphical displays that support pressurized water reactor (PWR) start-up. Specifically, a suite of displays was developed to support a PWR's feedwater (FW) system start-up as a proof-of-principle. The suite of displays demonstrate the theoretical design approach and are not meant to represent a fully implementable interface for FW system control. (author)

  13. A development of maintenance educational support method by using navigation method. Pt. 1. A conceptual design of RHR pump maintenance educational support prototype system

    International Nuclear Information System (INIS)

    The purpose of this research is before hand prevention of the systematic error produced from the fault of command / command system on the different organization in a nuclear power plant, and the individual error of the demand level of maintenance work, and knowledge and experience level of a maintenance worker produced from it being incongruent (mismatch), and generating of the serious accident and a serious trouble. This research attains optimization with the difficulty of maintenance work, and work execution capability, such as the persons concerned (a supervision person, a construction person, work person), and proposes the new 'maintenance educational support technique' which is useful to the improvement in 'work reliability' and 'before hand prevention of a human error' in the maintenance work spot. The main results concerning this research are shown below. (1) In this research, concept design of RHR pump maintenance work educational support prototype system was performed on the basis of the examination result of a process analysis of RHR pump maintenance work, load mapping, a rule base/knowledge base and a data base/filing system. Consequently, when an educator-ed talked with a data base/filing system along with load mapping of maintenance work (Why, How, What), a possibility that it could reach exactly from work start to the sub goal or the last goal and timely was suggested. (2) As a result of classifying 'the difficulty of maintenance work', and man's work execution capability' and comparing the result using SRK (behavior of human) index which Rasmussen proposed, among both, it turns out that difference (inharmonious) arises. The exact presentation of the educational method or educational material which responded to knowledge and experience level of an educational achievement target or an educator-ed can be referred to as being connected with the improvement in work reliability, and before hand prevention of a human error as a result by then, incorporating

    Bacillithiol (Cys-GlcN-malate, BSH) has recently been identified as a novel low-molecular weight thiol in Bacillus anthracis, Staphylococcus aureus, and several other Gram-positive bacteria lacking glutathione and mycothiol. We have now characterized the first two enzymes for the BSH biosynthetic pathway in B. anthracis, which combine to produce {alpha}-D-glucosaminyl L-malate (GlcN-malate) from UDP-GlcNAc and L-malate. The structure of the GlcNAc-malate intermediate has been determined, as have the kinetic parameters for the BaBshA glycosyltransferase ({yields}GlcNAc-malate) and the BaBshB deacetylase ({yields}GlcN-malate). BSH is one of only two natural products reported to contain a malyl glycoside, and the crystal structure of the BaBshA-UDP-malate ternary complex, determined in this work at 3.3 {angstrom} resolution, identifies several active-site interactions important for the specific recognition of L-malate, but not other {alpha}-hydroxy acids, as the acceptor substrate. In sharp contrast to the structures reported for the GlcNAc-1-D-myo-inositol-3-phosphate synthase (MshA) apo and ternary complex forms, there is no major conformational change observed in the structures of the corresponding BaBshA forms. A mutant strain of B. anthracis deficient in the BshA glycosyltransferase fails to produce BSH, as predicted. This B. anthracis bshA locus (BA1558) has been identified in a transposon-site hybridization study as required for growth, sporulation, or germination [Day, W. A., Jr., Rasmussen, S. L., Carpenter, B. M., Peterson, S. N., and Friedlander, A. M. (2007) J. Bacteriol. 189, 3296-3301], suggesting that the biosynthesis of BSH could represent a target for the development of novel antimicrobials with broad-spectrum activity against Gram-positive pathogens like B. anthracis. The metabolites that function in thiol redox buffering and homeostasis in Bacillus are not well understood, and we present a composite picture based on this and other recent work.

In this study, we estimated the attendance to the second-trimester fetal malformation screening program. We also estimated the positive predictive value (PPV of prenatally assigned International Classification of Disease-10 diagnoses recorded in the Danish National Patient Registry (DNPR and the completeness of case registration. We used kidney anomalies as an example. Methods: We identified the proportion of all Danish live-born children from January 1, 2007 to December 31, 2012, who were scanned during the second trimester using the DNPR and the Civil Registration System. Details of all fetuses with specific kidney anomaly diagnoses according to the DNPR were retrieved. The PPV was estimated using the nationwide Astraia database of pregnancy medical charts or traditional medical charts, as gold standard. The completeness was assessed using the total number of cases estimated by the capture–recapture method. Results: Of 372,263 live born infants, 97.3% were scanned during the second trimester. We identified 172 fetuses in the DNPR. Of these, 149 had kidney anomalies according to Astraia or medical chart review, corresponding to a PPV of 87% (95% CI: 81%–91%.

    In April and May 2007 the Regional HEP Team (RHT) conducted a follow-up HEP analysis on the Egger (612 acres) and Herzog (210 acres) parcels located at the north end of the Shillapoo Wildlife Area. The Egger and Herzog parcels have been managed with Bonneville Power Administration funds since acquired in 1998 and 2001 respectively. Slightly more than 936 habitat units (936.47) or 1.14 HUs per acre was generated as an outcome of the 2007 follow-up HEP surveys. Results included 1.65 black-capped chickadee HUs, 280.57 great blue heron HUs, 581.45 Canada goose HUs, 40 mallard HUs, and 32.80 mink HUs. Introduction A follow-up Habitat Evaluation Procedures (HEP) (USFWS 1980) analysis was conducted by the Columbia Basin Fish and Wildlife Authority's (CBFWA) Regional HEP Team (RHT) during April and May 2007 to document changes in habitat quality and to determine the number of habitat units (HUs) to credit Bonneville Power Administration (BPA) for providing operation and maintenance (O&M) funds since WDFW acquired the parcels. The 2007 follow-up HEP evaluation was limited to Shillapoo Wildlife Area (SWA) parcels purchased with Bonneville Power Administration funds. D. Budd (pers. comm.) reported WDFW purchased the 612 acre Egger Farms parcel on November 2, 1998 for $1,737,0001 and the 210 acre Herzog acquisition on June 21, 2001 for $500,000 with Memorandum of Agreement funds (BPA and WDFW 1996) as partial fulfillment of BPA's wildlife mitigation obligation for construction of Bonneville and John Day Dams (Rasmussen and Wright 1989). Anticipating the eventual acquisition of the Egger and Herzog properties, WDFW conducted HEP surveys on these lands in 1994 to determine the potential number of habitat units to be credited to BPA. As a result, HEP surveys and habitat unit calculations were completed as much as seven years prior to acquiring the sites. The term 'Shillapoo Wildlife Area' will be used to describe only the Herzog and Egger parcels in this

    Epilepsia Partialis Continua (EPC), a subtype of status epilepticus has varied etiology and the outcome depends on the cause. The aim of this study was to analyze the demographic, semiology, etiology, radiological findings, therapeutic response and outcome of EPC. This is a retrospective analysis of 76 patients (M:F: 46:30; mean age: 30.2+/-23.4 years; median age: 26 years) evaluated at our center over last 14 years. Twenty-three subjects (30.3%) had epilepsy for a mean of 25.8+/-52.3 months (range: 1-81 years; median: 14) before developing EPC and in half of them, seizures were controlled with anti-epileptic drugs (AEDs). Rest 53 (69.3%) manifested as de novo. The mean duration of EPC was 47.02+/-188.2 days (range: 1h to 48 months; median: 3 days). One patient of generalized convulsive SE (GCSE) evolved into EPC while five patients of EPC evolved into GCSE. CT scan of brain (n-76) was abnormal in 53 (69.7%) while all the 11 MRI scans which were available were abnormal. EEG (n-21) was abnormal in all but one, however it was non-specific in 7. The diagnoses were-idiopathic: 17, ischemic stroke: 15, meningo-encephalitis: 8, Rasmussen's encephalitis (RE): 7, granuloma: 6, diabetic-non-ketotic-hyperosmolar-coma (DNKHC): 6, CNS malignancies (primary/secondary): 4, birth injury: 4, cerebral venous thrombosis: 3, CNS tuberculosis: 2, and cerebritis, HIV-related, toxemia of pregnancy, and MERRF one each. Patients of >40 years (n=21) had stroke (10), idiopathic (6), DNKHC (4) and metastasis (1) as common causes. Only 12 of them received single AED, while others required 2 or more AEDs to control the seizures. The outcome (n=72) was-controlled: 43 (59.7%); uncontrolled: 26 (36.1%) (RE: 7, idiopathic: 5, birth injury: 4, encephalitis: 3, malignancy: 2, granuloma and MERRF: 1 each) and three patients succumbed (encephalitis: 2, idiopathic: 1). Causes of EPC are varied and it depends on age. Underlying cause determined the outcome and could be refractory in RE, idiopathic, and

    Project ALTKUL was commissioned by DONG E and P A/S and Nordsoefonden; the Danish Energy Agency followed the project closely. The first part of the study has been reported in Rasmussen and Thorning (2012).The starting point of the study was a need for more knowledge on methods that could be used for hydrocarbon exploration in Danish onshore areas, as an alternative to seismic investigations, when these cannot be used for nature protecting reasons. DONG E and P A/S and Nordsoefonden approached GEUS, suggesting a study of seven different non-seismic methods. The Danish Energy Agency was interested in the subject and requested that an actual test of a method be carried out as a part of the project. The optimum choice for a field test was an electromagnetic experiment with a galvanic controlled source (Rasmussen and Thorning, 2012). However, due to organisational issues and a limited timeframe of the project, the final choice of method for the field test was settled on using the magnetotelluric method (MT). Though MT does not utilise galvanic controlled sources, and hence does not serve as a tool for direct hydrocarbon exploration, MT has been used in the past in relation with hydrocarbon exploration onshore and has recently gained considerable interest in China. A contract was entered with Uppsala University for some initial tests of the magnetotelluric (MT) method. The test was carried out August 2012 in an area around Toender, and is reported here as ALTKUL Project Report Part 2. In total 42 MT stations were measured in a 180 km{sup 2} area. The digital data are enclosed with the report and hereby released to the public. A 3D model of the electrical resistivity variations to a depth of 6 km constitutes, together with the actual measured data, the main results of part 2 of the ALTKUL project. The 3D model was derived from an unconstrained 3D inversion of the MT data. The MT data show that pronounced lateral resistivity variations exist at the depth of interest for

    auxiliary role of 3D printing technique in preoperative plan and treatment for tibial plateau fractures. METHODS:Thirty patients with tibial plateau comminuted fractures were enroled in this study and divided into two groups: experimental and control groups, with 15 patients in each group. In the experimental group, patients underwent 3D CT scan, which was stored in DICOM format, and processed by Mimics software. Data were converted into STL format, entered 3D printer, and a 1:1 entity size of the fracture model was made, in accordance with repair plan of 3D fracture model. Operation time and intraoperative blood loss were compared between the two groups. At 12 months after treatment, their outcomes were assessed using Rasmussen evaluation criteria. RESULTS AND CONCLUSION: The 3D printing fracture models of 1:1 ratio identified fracture type and made a repair program before surgery in the experimental group. Operation time and intraoperative blood loss were significantly less in the experimental group than in the control group (P < 0.05). After surgery, patients were folowed up for 12 to 18 months. The healing time was 3-5 months, averagely 4.3 months. At 12 months after treatment, the Rasmussen evaluation criteria results showed that the excelent and good rate was significantly higher in the experimental group than in the control group (P < 0.05). These results suggest that the fracture model of 3D can help to make the operation plan. The treatment of tibial plateau fractures is more precise, personalized and visual.

    particles in the atmosphere, droplets trajectories are calculated to obtain the collection efficiency associated with different drop size distribution and varying the wind speed. The main benefit of investigating this error by means of CFD simulations is the possibility to single out the prevailing environmental factors from the instrumental performance of the gauges under analysis. The preliminary analysis shows the variations in the catch efficiency due to the horizontal wind speeds and the DSD. Overall, this study contributes to a better understanding of the environmental sources of uncertainty in rainfall measurements. References: Colli, M., R. Rasmussen, J. M. Theriault, L. G. Lanza, C.

  6. Mass-balance Approach to Interpreting Weathering Reactions in Watershed Systems

    2003-12-01

    The mass-balance approach is conceptually simple and has found widespread applications in many fields over the years. For example, chemists use mass balance (Stumm and Morgan, 1996) to sum the various species containing an element in order to determine the total amount of that element in the system (free ion, complexes). Glaciologists use mass balance to determine the changes in mass of glaciers ( Mayo et al., 1972 and references therein). Groundwater hydrologists use this method to interpret changes in water balance in groundwater systems ( Rasmussen and Andreasen, 1959; Bredehoeft et al., 1982; Heath, 1983; Konikow and Mercer, 1988; Freeze and Cherry, 1979; Ingebritsen and Sanford, 1998). This method has also been used to determine changes in chemistry along a flow path ( Plummer et al., 1983; Bowser and Jones, 1990) and to quantify lake hydrologic budgets using stable isotopes ( Krabbenhoft et al., 1994). Blum and Erel (see Chapter 5.12) discuss the use of strontium isotopes, Chapelle (see Chapter 5.14) treats carbon isotopes in groundwater, and Kendall and Doctor (see Chapter 5.11) and Kendall and McDonnell (1998) discuss the use of stable isotopes in mass balance. Although the method is conceptually simple, the parameters that define a mass balance are not always easy to measure. Watershed investigators use mass balance to determine physical and chemical changes in watersheds ( Garrels and Mackenzie, 1967; Plummer et al., 1991; O'Brien et al., 1997; Drever, 1997). Here we focus on describing the mass-balance approach to interpret weathering reactions in watershed systems including shallow groundwater.Because mass balance is simply an accounting of the flux of material into a system minus the flux of material out of the system, the geochemical mass-balance approach is well suited to interpreting weathering reactions in watersheds (catchments) and in other environmental settings (Drever, 1997). It is, perhaps, the most accurate and reliable way of defining

    'We travelled in the winter after the return of daylight and did not go into fixed camp until spring, when the ice broke up. There was good hunting on the way, seals, beluga, walrus, bear.' (From Old Merkrusârk's account of his childhood's trek from Baffin Island to Northwest Greenland, told to Knud Rasmussen on Saunders Island in 1904) Five thousand years ago people moving eastwards from Beringia spread over the barrens of the Canadian high Arctic. This was the first of three waves of prehistoric Arctic 'cultures', which eventually reached Greenland. The passage into Greenland has to go through the northernmost and most hostile part of the country with a 5 month Polar night, and to understand this extraordinary example of human behaviour and endurance, it has been customary to invoke a more favourable (warmer) climate. This presentation suggests that land-fast sea ice, i.e. stationary sea ice anchored to the coast, is among the most important environmental factors behind the spread of prehistoric polar cultures. The ice provides the road for travelling and social communion - and access to the most important source of food, the ocean. In the LongTerm Project (2006 and 2007) we attempted to establish a Holocene record for sea ice variations along oceanic coasts in northernmost Greenland. Presently the coasts north of 80° N are beleaguered by year-round sea ice - for ten months this is land-fast ice, and only for a period in the stormy autumn months are the coasts exposed to pack-ice. This presentation Land-fast ice - as opposed to pack-ice - is a product of local temperatures, but its duration over the year, and especially into the daylight season, is also conditioned by other factors, notably wind strength. In the geological record we recognize long lasting land-fast ice by two absences: absence of traces of wave action (no beach formation), which, however, can also be a result of pack-ice along the coast; - and absence of driftwood on the shore (land-fast ice

    Macropores generate rapid flow paths in the surface soils by their high permeability under saturated/near-saturated moisture conditions. In natural soils, some macropores are filled/coated with various materials including decayed plant roots (Meek et al., 1989), exudates from plants/soil organisms (Jegou et al., 2001), iron oxides or other precipitates from preferentially-introduced solutes/colloids to the macropores (Rasmussen et al., 2001), or the surrounding soils with reduced bulk density (Ela et al., 1992). When we expect infiltration into water repellent soils through macropores or hydrophilic patches created from the macropore cementation processes, hydrophilicity of the macropore fillings/coatings should be understood. In the present study, we conducted an infiltration experiment with water repellent porous media and some macropore fillings/coatings, in order to clarify the roles of hydrophilic macropore fillings/coatings in infiltration. Ponding depth and flow distribution were monitored with a micro-focus X-ray computational tomography apparatus (SMX-90CT, Shimadzu Corp., Kyoto, Japan) at 90 kV and 110 μA. Dilute CsCl(aq) (density: 1.04 Mg m-3) was used as the contrast media to avoid density-driven alteration of the flows. Water repellency of the samples was evaluated by the water drop penetration time (WDPT, Van't Woudt, 1959). A glass beads (mean diameter: 0.46 mm, BZ-04, ASONE Corp., Osaka, Japan) was used as water repellent porous media. The glass beads sample was packed in 50-mL polypropylene centrifugation tubes at 1.55 Mg m-3 bulk density. A 2-mm hole was made at the bottom of each centrifugation tube for ventilation. The hole was covered with mesh cloth. Macroporous structure was made at the center of each tube from the surface. Each macroporous structure had 4-mm diameter and 30-mm length. Six types of macropores were prepared including 1) no macropore, 2) empty macropore, 3) an aluminum (Al) pipe (4-mm inner diameter, 5-mm outer diameter), 4) a

  12. Geoethics disgraced by Copernicus in its desperate act of covering up for the IPCC

    2014-05-01

    All my life I have put observational facts in the centre. This is what Leonardo da Vinci called "to read the book of mother Earth". For a geologist this is very natural because this is the core of the geological profession. The IPCC, on the other hand, put all credits on models and scenarios. One of its founders and its first president, Bert Bolin, at a debate in the Geophysical Society of Sweden in 2001, admitted (quotation): "you can order whatever scenario you wish". With this as a background, we can put a recent action by Copernicus at a test with respect to geoethics and normal decency. The idea that the planetary motions affect and control the solar variability is old, but in the stage of an unproven hypothesis. In recent years major advancements have occurred and in 2013, it seemed that time was ripe for a major, multi-authored, reinvestigation. Therefore, a Special Issue of Pattern Recognition in Physics was devoted to: "Pattern in solar variability, their planetary origin and terrestrial impacts". The volume includes 12 separate research papers and General Conclusions, co-authored by 19 prominent scientists. Indeed, they agreed that the driving factor of solar variability must emerge from the planetary beat on the Sun, and by that its emission of luminosity and Solar Wind both factors of which affect the Earth-Moon system. This may be held as a benchmark event in our understanding of the planetary-solar-terrestrial interaction. Furthermore, they noted two implications of this: partly that the old hypothesis was now lifted to a firm theory, maybe even a new paradigm, and partly that we are on our way into a new grand solar minimum which "sheds serious doubts on the issue of a continued, even accelerated, warming as claimed by the IPCC". "We were alarmed by the second implication", Martin Rasmussen, VD of Copernicus, stated, and took the unbelievable decision immediately to close down the entire journal. This happened on January 17 without any discussion

The number of complications, such as ankylosis, fracture delayed union, pin tract infection, delayed union, varus deformity, was significantly fewer in the dual-incision double-plate fixation group than in the locking plate fixation group (P0.05). Postoperative Rasmussen classification was significantly better in the dual-incision double-plate fixation group than in the locking plate fixation group (P<0.05). Experimental results indicated that the clinical efficacy of the dual-incision double-plate fixation is superior to that of the anterior cruciate midline incision locking plate fixation in the treatment of Schatzker V, VI type tibial plateau fractures. The dual-incision double-plate fixation has more biomechanical stability.

Meanwhile from 2002- 2008, a right-wing government lead by Anders Fogh Rasmussen (AFR closed down innovative democracy process and a “non-policy” relying on existing market actors and existing market conditions was implemented. In this period the development of renewable energy was almost brought to a halt. But in 2008 AFR made a political u-turn, and declared his support to a 100% Renewable Energy future. In 2012 a new center left Government made an energy plan with the goal of 100% Renewable Energy in 2050. This  goal was supported by a large majority in the Parliament in an agreement in 2012. The

    International Nuclear Information System (INIS)

    and the will to carry out the maintenance task are thus weakened. Structural and cultural issues affect the individual, but the influence goes to the other direction also. Weakened sense of control among a lot of employees can gradually lead to avoiding and self-defensive culture, and this in turn can eventually influence for example procedures that are taken into use, or the choice of tools deemed necessary to carry out the task. These kinds of influences have been depicted by e.g. Vicente (2004), Rasmussen (1997) and Snook (2000). Vicente (2004: 276) writes further that 'accidents in complex technological systems don't usually occur because of an unusual action or an entirely new, one-time threat to safety. Instead, they result from a systematically induced migration in work practices combined with an odd event or coincidence that winds up revealing the degradation in safety that has been steadily increasing all the while'. Snook (2000) concludes on the basis of his extensive accident analysis of a shoot down of two friendly helicopters in Iraq airspace that one of the reasons for the accident was what he calls practical drift of the practices. He writes: 'practical drift is the slow steady uncoupling of practice from written procedure' where 'locally practical actions within subgroups gradually drift away from originally established procedures-those conservatively written rules designed to handle the worst-case condition when subunits are tightly coupled' (Ibid: 194). These changes are incremental and not usually perceived as changes at all; they are part of the everyday work. This makes them especially difficult to explicitly manage. In summary, maintenance activities have been under various restructuring initiatives in addition to continuous incremental change due to new technologies, ageing plants etc. These changes have been experienced as causing stress and uncertainty among the workers. Also, changes have lead to e.g. lowered sense of control, goal un
