    Rasmussen encephalitis (RE) is a rare devastating disease of childhood causing progressive neurological deficits and intractable seizures, typically affecting one hemisphere. Characteristic MRI features include progressive unihemispheric focal cortical atrophy and grey- or white-matter high-signal changes and basal ganglion involvement, particularly of the caudate nucleus. To analyse the pattern of involvement of different brain structures in a series of patients with RE and to attempt clinical correlation. We reviewed the medical records and neuroimaging data of 12 patients diagnosed with RE satisfying the European Consensus Statement diagnostic criteria. The disease manifested as seizures in all patients and was refractory; epilepsia partialis continua was a notable feature (nine patients). Hemiparesis of varying grades was noted in all but one patient; none had extrapyramidal signs. Neuroimaging showed cortical involvement in the insular/periinsular regions in 11 patients. Caudate atrophy was noted in ten patients. Putaminal atrophy was seen in nine patients, six of whom had additional hyperintense signal changes. Our study highlights frequent putaminal atrophy and signal changes in RE, which suggests a more extensive basal ganglion involvement than emphasized previously. Recognition of putaminal changes may be a useful additional tool in the radiological diagnosis of RE. (orig.)

    Rasmussen's syndrome is characterized by intractable seizures and progressive neuropsychiatric deterioration secondary to unilateral cortical inflammation and tissue destruction. Diagnosis of Rasmussen's syndrome in the early phase depends mainly on the clinical features. Neuroimaging and histopathologic examinations may not be specific during this period. We report a case of Rasmussen's syndrome followed by serial MRI and magnetic resonance spectroscopy (MRS) studies over a 3- to 16-month period. A healthy 6-year-old boy presented with focal motor seizures. An MRI study demonstrated prominent enlargement and T2 hyperintensity of the left mesial temporal lobe and perisylvian region. This early finding evolved to volume loss and later progressive atrophy of the ipsilateral hemisphere when epilepsia partialis continua occurred. Being aware of those early MRI features in a patient with increasing frequency of focal motor seizures should suggest Rasmussen's syndrome. In addition, we found prominently increased myoinositol concentration in atrophic cortex which might reflect increased gliosis in the late period of the disease. (orig.)

    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

    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)

    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.)

    Rasmussen encephalitis (RE) is a severe epileptic and inflammatory encephalopathy of unknown etiology, responsible for focal neurological signs and cognitive decline. The current leading hypothesis suggests a sequence of immune reactions induced by an indeterminate factor. This sequence is thought to be responsible for the production of autoantibody-mediated central nervous system degeneration. However, these autoantibodies are not specific to the disease and not all patients present with them. We report the case of a 4-year-old girl suffering from RE displaying some atypical features such as fast evolution and seizures of left parietal onset refractory to several antiepileptics, intravenous immunoglobulins, and corticosteroids. Serum autoantibodies directed against voltage-gated potassium channels (VGKC) were evidenced at 739 pM, a finding never previously reported in children. This screening was performed because of an increased signal in the temporolimbic areas on brain magnetic resonance imaging, which was similar to what is observed during limbic encephalitis. The patient experienced epilepsia partialis continua with progressive right hemiplegia and aphasia. She underwent left hemispherotomy at the age of 5.5 years after which she became seizure free with great cognitive improvement. First described in adults, VGKC autoantibodies have been recently described in children with various neurological manifestations. The implication of VGKC autoantibodies in RE is a new observation and opens up new physiopathological and therapeutic avenues of investigation.

    2006-01-01

    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.

    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 ({sup 1}HMRS) 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).

    cross-links identified imply the structural differences. Specifically, when the ANA domain is proteolytically removed during the conversion of C3 to C3b, seven cross-links between the ANA domain and the surrounding domains in C3 are replaced by three cross-links connected to the newly created N......-terminus. The TED domain relocates as is revealed by three cross-links to the ANA domain in C3 and four cross-links to the MG1 domain in C3b, a domain that is remote in C3. In C3b case, a cross-link within the CUB domain suggests a folded structure of this domain, a matter of dispute in the competing crystal...

    Aim Complete genome amplification of viral RNA provides a new tool for generation of modified pestiviruses. We have recently reported a full genome amplification strategy for direct recovery of infectious pestivirus (Rasmussen et al., 2008). This comprised rescue of BDV strain “Gifhorn” from a full......-length RT-PCR amplicon demonstrating that long RT-PCR can be used for direct generation of an infectious pestivirus. The strategy is not limited to amplification of BDV “Gifhorn”, but can be further utilized for amplification of a diverse selection of pestivirus strains and for the generation of modified...... of an existing infectious clone. The long RT-PCR strategy significantly simplifies and streamlines the workflow and facilitates generation of new modified pestiviruses and also allows direct full-length sequence analysis.

  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.

  5. 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

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.

  5. 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

  6. 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

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. The results showed that both sectors were considered key sectors only by the Rasmussen-Hirschman index and the influence field index, i.e., they presented greater importance when observed its impacts on the final demand and its power of enchainment in the economy. Despite not being considered key sectors by the GHS index, they presented great potential of backward impacts. This result, and the fact that the participation of these sectors had been increasing in the Minas Gerais economy since 1995, suggests that those sectors the state policy makers need to give priority in resources allocation and in the

    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

    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

    The author deals with the three phases of release from the reactor core, from the reactor system, and finally from the containment. 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)

    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.

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

    Science.gov (United States)

    Colli, Matteo; Lanza, Luca; Rasmussen, Roy; Thériault, Julie

    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.

  3. 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

    Using high resolution chemical impurity and dielectric profiling data annual layers have been counted on the EPICA ice core from Dronning Maud Land (EDML), Antarctica spanning the past 16700 years. The methodology used for counting Greenland ice cores and creating the Greenland Ice Core Chronology 2005 (GICC05) [Rasmussen et al., 2006] has also been implemented for the EDML counting. The estimated maximum counting error for the EDML counting is approx. 5%, but a preliminary volcanic matching with Greenland ice core records suggest differences of 1% or less during the Holocene between the EDML counting and GICC05. A comparison of cosmogenic isotope records from EDML and Greenland also suggests differences of less than 1% between the two annual layer counted chronologies.

  6. 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

    Recent studies on driver behaviour have shown that perception - mainly visual but also proprioceptive perception - plays a key role in the ''driver-vehicle-road'' system and so considerably affects the driver's decision making. Within the framework of the behaviour analysis and studies low-cost system (BASIL), this paper presents a correlative, qualitative and quantitative study, comparing the information given by visual perception and by the trajectory followed. This information will help to obtain a cognitive model of the Rasmussen type according to different driver classes. Many experiments in real driving situations have been carried out for different driver classes and for a given trajectory profile, using a test vehicle and innovative, specially designed, real-time tools, such as the vision system or the positioning module.

  12. Flexicurity in the Current Economic and Social Context

    Directory of Open Access Journals (Sweden)

    Georgeta Modiga

    2015-05-01

    Full Text Available The flexicurity concept - an abbreviation between flexibility and security - appeared in the early 90s, being used for the first time by the Danish Prime Minister Poul Nyrum Rasmussen. The concept refers to a social state model that promotes a pro-active policy in the labour domain and the access to employment. Flexicurity can be defined as a strategy integrated by the simultaneous consolidation of flexibility and security on the labour market. According to the definition given by the European Commission, which establishes the guidelines and “paths” typical for the Member States in order to develop their own strategies in the field, flexicurity is an integrated strategy of simultaneous strengthening of flexibility and security on labour market. This concept arose as a result of socio-economic changes registered in the last decades in Europe: globalization and European integration, development of new technologies, the demographic aging of European society, the segmented development of labour markets.

    The wide-angle PE method is applied to the prediction of sound propagation in a range-dependent environment. The finite-difference model treats the sloping ground by a staircase approximation. The method allows impedance and slope angle variations to be taken into account. The implementation...... of sloping interfaces in one-way PE models introduces a fundamental problem of energy conservation. This is generated at the lower boundary condition.

  18. 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.

    2012-06-01

    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.

  2. New Approaches to Classical Liberalism

    Directory of Open Access Journals (Sweden)

    Nicolas Maloberti

    2012-01-01

    Full Text Available This article focuses on the following three novel and original philosophical approaches to classical liberalism: Den Uyl and Rasmussen's perfectionist argument from meta-norms, Gaus's justificatory model, and Kukathas's conscience-based theory of authority. None of these three approaches are utilitarian or consequentialist in character. Neither do they appeal to the notion of a rational bargain as it is typical within contractarianism. Furthermore, each of these theories rejects the idea that classical liberalism should be grounded on considerations of interpersonal justice such as those that are central to the Lockean tradition. It is argued that these three theories, despite their many attractive features, fail to articulate in a convincing manner some central classical liberal concerns.

    2001-01-01

    Removal of the oxcarbazepine metabolite 10-hydroxycarbazepine (MHD) by plasmapheresis was evaluated during a series of six plasmaphereses of a 13-year-old boy with Rasmussen encephalitis. Plasmapheresis was performed after steady-state concentrations of MHD had been achieved with a dose of 2550 mg...... oxcarbazepine daily. The mean amount of MHD removed per plasmapheresis was 78.9 mg (SD: 6.0 mg), representing 3% to 4% of the daily oxcarbazepine dose and approximately 5% to 6% of body stores of MHD. The mean steady-state trough MHD concentration was 33.3 mg/L (SD: 1.8 mg/L), and this was remarkably stable...... performing single-volume plasma exchanges or even multiple exchanges during an extended period. It is further proposed that plasmapheresis is unlikely to be of therapeutic benefit in the treatment of an oxcarbazepine overdose. Udgivelsesdato: 2001-Aug...

    2016-02-01

    Chemokine receptors have been implicated in a wide range of CNS inflammatory diseases and have important roles in the recruitment and positioning of immune cells within tissues. Among them, the chemokine (C-C motif) receptor 5 (CCR5) can be targeted by maraviroc, a readily available and well-tolerated drug that was developed for the treatment of HIV. Correlative evidence implicates the CCR5-chemokine axis in multiple sclerosis, Rasmussen encephalitis, progressive multifocal leukoencephalopathy-associated immune reconstitution inflammatory syndrome, and infectious diseases, such as cerebral malaria and HIV-associated neurocognitive disorders. On the basis of this evidence, we postulate in this Review that CCR5 antagonists, such as maraviroc, offer neuroprotective benefits in settings in which CCR5 promotes deleterious neuroinflammation, particularly in diseases in which CD8(+) T cells seem to play a pivotal role.

  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.

    If the military were a business, would you buy shares? Over recent years, Western armed forces, particularly the US, have been costing more yet achieving less. At the same time, austerity measures are reducing defence budgets. This book uses defence data to examine the workings of modern Western...... militaries and explore what kind of strategies can overcome this gap between input and output. Instead of focusing on military strategy, Mikkel Vedby Rasmussen seeks to draw on the ideas of business strategy to assess alternative business cases - reforming military HR to combat instability in the 'Global...... South' or utilising new technologies to overcome the prohibitive costs of current systems. Analysing the philosophical, strategic and budgetary underpinnings of these alternatives, he concludes that a more radical break from current military organisational practices is needed which would allow them...

    Pressure parameters are added to the Extended UNIQUAC model presented by Thomsen and Rasmussen (Modeling of vapor-liquid-solid equilibrium in gas-aqueous electrolyte systems. Chemical Engineering Science 54, 1787-1802, 1999). The improved model has been used for correlation and prediction of solid-liquid equilibrium (SLE) of scaling minerals (CaSO{sub 4}, CaSO{sub 4}.2H{sub 2}O, BaSO{sub 4} and SrSO{sub 4}) at temperatures up to 300{sup o}C and pressures up to 1000 bar. The results show that the Extended UNIQUAC model, with the proposed pressure parameters, is able to represent binary, ternary and quaternary solubility data within the experimental accuracy in the temperature range from -20 to 300{sup o}C, and the pressure range from 1 to 1000 bar.

    2009-01-01

    Full Text Available In this study, the leading activities of Turkish Economy whose changes in their structure of production, value-added and employment are interrelated with the other activities of the economy, are found by using the input-output model which is presented and called as an 'Application of the General Equilibrium Theory' by Leontief. For this purpose; firstly theoretical foundations of the input-output model are examined. After that, 59 activities of the 2002 Input-Output Table of the Turkish Economy are aggregated at 52 sectors and classified into three categories as Ricardo Sectors, High-Technology Sectors and Heckscher-Ohlin Sectors like Dasgupta and Chakraborty did for the Indian Economy in 2005. Then, the leading, key or strong activities of the economy that are more interrelated with other activities are calculated and found by the Static Leontief Model which is used by the Traditional Methods as the techniques to calculate the linkage effects like Chenery-Watanabe and Rasmussen methods to determine the sectors having the highest priority at investment policies according to the Hirschmanian Unbalanced Growth Model. As a result of the interpretation of Leontief Model, using the traditional methods of Chenery-Watanabe and Rasmussen while calculating the linkage effects rather than the hypothesis extraction methods like Strassert's Original Extraction Method, Cella's Extraction Method, Sonis' Pure Linkage Method and Dietzenbacher and Van der Linden's Method or a SAM (Social Accounting Method model which does not omit the income generating process (distributing income among primary factors and households as a result of production of a sector, in Turkey, the Heckscher-Ohlin Sectors mostly seen in the manufacturing industry which Kaldor refers as the engine of growth, are stronger than the other sectors.

  19. 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

  20. Systems-based approach to investigate unsafe pedestrian behaviour at level crossings.

    Crashes at level crossings are a major issue worldwide. In Australia, as well as in other countries, the number of crashes with vehicles has declined in the past years, while the number of crashes involving pedestrians seems to have remained unchanged. A systematic review of research related to pedestrian behaviour highlighted a number of important scientific gaps in current knowledge. The complexity of such intersections imposes particular constraints to the understanding of pedestrians' crossing behaviour. A new systems-based framework, called Pedestrian Unsafe Level Crossing framework (PULC) was developed. The PULC organises contributing factors to crossing behaviour on different system levels as per the hierarchical classification of Jens Rasmussen's Framework for Risk Management. In addition, the framework adapts James Reason's classification to distinguish between different types of unsafe behaviour. The framework was developed as a tool for collection of generalizable data that could be used to predict current or future system failures or to identify aspects of the system that require further safety improvement. To give it an initial support, the PULC was applied to the analysis of qualitative data from focus groups discussions. A total number of 12 pedestrians who regularly crossed the same level crossing were asked about their daily experience and their observations of others' behaviour which allowed the extraction and classification of factors associated with errors and violations. Two case studies using Rasmussen's AcciMap technique are presented as an example of potential application of the framework. A discussion on the identified multiple risk contributing factors and their interactions is provided, in light of the benefits of applying a systems approach to the understanding of the origins of individual's behaviour. Potential actions towards safety improvement are discussed.

  2. Pseudopollen in Dendrobium unicum Seidenf. (Orchidaceae): Reward or Deception?

    Science.gov (United States)

    DAVIES, K. L.; TURNER, M. P.

    2004-01-01

    • Background and Aims In 1987, Kjellsson and Rasmussen described the labellar trichomes of Dendrobium unicum Seidenf. and proposed that these hairs function as pseudopollen. Pseudopollen is a mealy material that superficially resembles pollen, is usually laden with food substances and is formed when labellar hairs either fragment into individual cells or become detached from the labellum. However, the trichomes of D. unicum are very different from pseudopollen‐forming hairs found in other orchid genera such as Maxillaria and Polystachya. Moreover, Kjellsson and Rasmussen were unable to demonstrate the presence of food substances within these trichomes and argued that even in the absence of food substances, the hairs, in that they superficially resemble pollen, can still attract insects by deceit. The aim of this paper is to investigate whether the labellar trichomes of D. unicum contain food reserves and thus reward potential pollinators or whether they are devoid of foods and attract insects solely by mimicry. • Methods Light microscopy, histochemistry and transmission electron microscopy. • Key Results Dendrobium unicum produces pseudopollen. Pseudopollen here, however, differs from that previously described for other orchid genera in that the pseudopollen‐forming trichomes consist of a stalk cell and a ‘head’ of component cells that separate at maturity, in contrast to Maxillaria and some Polystachya spp. where pseudopollen is formed by the fragmentation of moniliform hairs. Moreover, the pseudopollen of Maxillaria and Polystachya largely contains protein, whereas in D. unicum the main food substance is starch. • Conclusions Flowers of D. unicum, rather than attracting insects solely by deceit may also reward potential pollinators.

    There is growing evidence that variability in the size and heat content of the tropical Atlantic Warm Pool impacts circum-North Atlantic climate via the Atlantic Multi-decadal Oscillation mode (Wang et al., 2008). The Atlantic Warm Pool spans the Gulf of Mexico, Caribbean Sea and the western tropical North Atlantic. Barbados is located near the center of the tropical Atlantic Warm Pool and coupled ocean models suggest that Barbados remains near the center of the tropical Atlantic Warm Pool under varying wind stress simulations. Measurements of the oxygen isotope paleothermometer in Acropora palmata coral species recovered from cores offshore Barbados, show a 3oC monotonic decrease in sea surface temperature from 13106 ± 83 to 12744 ± 61 years before present (errors given as 2 sigma). This interval corresponds to a sea level rise from 71.4 meters to 67.1 meters below present levels at Barbados. The 3oC temperature decrease is captured in eight A. palmata specimens that are in stratigraphic sequence, 230Th/234U dated, and analyzed for oxygen isotopes. All measurements are replicated. We are confident that this is the warm pool equivalent of the Younger Dryas climate event. The initiation of this temperature drop in the Atlantic Warm Pool predates the Younger Dryas start in Greenland ice cores, reported to start at 12896 ± 138 years (relative to AD 2000) (Rasmussen et al., 2006), while few other Younger Dryas climate records are dated with similar accuracy to make the comparison.

    During glacial periods, Earth experienced abrupt climate change events that led to rapid natural warming/ cooling over a few years only (Steffensen et al., 2008). In order to investigate these rapid climate events especially in old thinned ice, highest spatial/time resolution analysis of climate proxies is required. A recently developed methodology at Royal Holloway University of London (Müller et al., 2011), which permits in situ chemical analysis of frozen ice with spatial (and thus time) resolution up to 0.1 mm (100 ?m) using cryo-cell UV-laser ablation inductively-coupled-plasma mass spectrometry (UV-LA-ICPMS), has been optimized and utilized for analysis of (major) elements indicative of dust and/or sea salt (e.g. Fe, Al, Ca, Mg, Na), while maintaining detection limits in the low(est) ppb-range. NGRIP samples of Greenland Stadial GS22 (~86 ka, depth of ~2690 m), representing a minor δ18O shift (of about ± 4) within the stadial phase of D-O event 22, have been selected and analysed. With a single storm-event resolution capability, seasonal, annual and multiannual periodicity of elements have been identified and will be presented with particular focus on the phasing of the climate proxies. Corresponding results include also an optimized UV-LA-ICPMS methodology, particularly with reference to depth-profiling, assessing contamination of the sample surface and standardization. Finally, the location and distribution of soluble and insoluble micro-inclusions in deep ice have also been assessed concerning the partitioning of elements between grain boundaries and grain interiors. Results show that impurities tend to be concentrated along boundaries in clear (winter) ice, whereas in cloudy bands ('dirtier' ice) they distribute equally between boundaries and interiors.

    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

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

    Norton, K. P.

    2013-12-01

    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)

  8. Modeling of a photosynthetic crop production index for early warning using NDVI and meteorological data

    2004-10-01

    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.

  9. In vivo deposition of ultrafine aerosols in human nasal and oral airways

    International Nuclear Information System (INIS)

    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 μm particles in 10 human subjects and in our preliminary studies using 0.004-0.15 μm 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 μm with the nasal dimensions of each subject

  11. 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)

  14. An Aristotelian account of minimal chemical life.

    Science.gov (United States)

    Bedau, Mark A

    2010-12-01

    This paper addresses the open philosophical and scientific problem of explaining and defining life. This problem is controversial, and there is nothing approaching a consensus about what life is. This raises a philosophical meta-question: Why is life so controversial and so difficult to define? This paper proposes that we can attribute a significant part of the controversy over life to use of a Cartesian approach to explaining life, which seeks necessary and sufficient conditions for being an individual living organism, out of the context of other organisms and the abiotic environment. The Cartesian approach contrasts with an Aristotelian approach to explaining life, which considers life only in the whole context in which it actually exists, looks at the characteristic phenomena involving actual life, and seeks the deepest and most unified explanation for those phenomena. The phenomena of life might be difficult to delimit precisely, but it certainly includes life's characteristic hallmarks, borderline cases, and puzzles. The Program-Metabolism-Container (PMC) model construes minimal chemical life as a functionally integrated triad of chemical systems, which are identified as the Program, Metabolism, and Container. Rasmussen diagrams precisely depict the functional definition of minimal chemical life. The PMC model illustrates the Aristotelian approach to life, because it explains eight of life's hallmarks, one of life's borderline cases (the virus), and two of life's puzzles.

    1993-08-01

    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.

  16. 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

    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.)

  1. 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.

    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.

    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.

    Imaging of epilepsy patients is challenging, since epileptogenic lesions (defined as structural lesions causally related to the epilepsy syndrome) may be small and often do not change during life. Prior clinical information about the epilepsy syndrome and the semiology of the seizures is needed in order to plan the examination properly. The effort to detect an epileptogenic lesion is directed to partial (focal) epilepsy syndromes whereas - by definition - no lesion is identified in idiopathic epilepsies. Most patients with partial epilepsies suffer from mesial temporal lobe epilepsies. In these patients, 2- to 3-mm-thick T2-weighted and fluid-attenuated inversion-recovery (FLAIR) fast spin echo slices along or perpendicular to the temporal lobe length axis have the highest diagnostic efficacy. In contrast, in patients with extratemporal lobe epilepsies perpendicular FLAIR slices through the anatomic region, from which, due to clinical and EEG criteria, the seizures are likely to originate, are preferred. The imaging features of common epileptogenic lesions (hippocampal sclerosis, long-term epilepsy-associated tumours, focal cortical dysplasias, vascular malformations, encephalitis including limbic and Rasmussen's encephalitis, gyral scarring including ulegyria) are detailed in the second section of this paper.

    A series of nine XMM-Newton observations of the radio-loud quasar 3C 273 are presented, concentrating mainly on the soft excess. Although most of the individual observations do not show evidence for iron emission, co-adding them reveals a weak, broad line (EW ~ 56 eV). The soft excess component is found to vary, confirming previous work, and can be well fitted with multiple blackbody components, with temperatures ranging between ~40 and ~330 eV, together with a power-law. Alternatively, a Comptonisation model also provides a good fit, with a mean electron temperature of ~350 eV, although this value is higher when the soft excess is more luminous over the 0.5-10 keV energy band. In the RGS spectrum of 3C 273, a strong detection of the OVII He-alpha absorption line at zero redshift is made; this may originate in warm gas in the local intergalactic medium, consistent with the findings of both Fang et al. (2003) and Rasmussen et al. (2003).

    Full Text Available This article discusses the relationship between practice and research in the making disciplines. The discussion is based on a systems theory with reference to the German sociologist Niklas Luhmann (2007 and the way Rasmussen, Kruse and Holm (2007 use Luhmann´s theory. This article constructs and emphasizes the fundamental difference between the practice system and the scientific system. Furthermore, it highlights the distinctions between practice as the development of knowledge and research as the generation of knowledge. In addition to these boundaries, the following four different forms of knowledge are classified and described:1 practical knowledge and 2 professional knowledge, which are both associated with the practice system, and 3 research knowledge and 4 philosophy of science knowledge, which are associated with the scientific system. While emphasizing a fundamental difference between the practice system and the scientific system, this article assumes that art and design research should deal with aspects from both systems. The systems theory term ‘structural coupling’ offers a way to enable the two systems to influence each other while maintaining their own boundaries. Insider research is a structural coupling between the practice system and the scientific system. By exploring art and design processes from within as both the practitioner and the researcher, it is possible to generate knowledge both about and for practice. This article considers art and design research as a subsystem of the scientific system and argues that this approach may strengthen the further development of art and design research.

  10. An Aristotelian Account of Minimal Chemical Life

    Bedau, Mark A.

    2010-12-01

    This paper addresses the open philosophical and scientific problem of explaining and defining life. This problem is controversial, and there is nothing approaching a consensus about what life is. This raises a philosophical meta-question: Why is life so controversial and so difficult to define? This paper proposes that we can attribute a significant part of the controversy over life to use of a Cartesian approach to explaining life, which seeks necessary and sufficient conditions for being an individual living organism, out of the context of other organisms and the abiotic environment. The Cartesian approach contrasts with an Aristotelian approach to explaining life, which considers life only in the whole context in which it actually exists, looks at the characteristic phenomena involving actual life, and seeks the deepest and most unified explanation for those phenomena. The phenomena of life might be difficult to delimit precisely, but it certainly includes life's characteristic hallmarks, borderline cases, and puzzles. The Program-Metabolism-Container (PMC) model construes minimal chemical life as a functionally integrated triad of chemical systems, which are identified as the Program, Metabolism, and Container. Rasmussen diagrams precisely depict the functional definition of minimal chemical life. The PMC model illustrates the Aristotelian approach to life, because it explains eight of life's hallmarks, one of life's borderline cases (the virus), and two of life's puzzles.

    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.

  13. The Electronic Behavior of Zinc-Finger Protein Binding Sites in the Context of the DNA Extended Ladder Model

    2016-05-01

    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.

  14. 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)

  15. Influence of magnetospheric inputs definition on modeling of ionospheric storms

    Science.gov (United States)

    Tashchilin, A. V.; Romanova, E. B.; Kurkin, V. I.

    Usually for numerical modeling of ionospheric storms corresponding empirical models specify parameters of neutral atmosphere and magnetosphere. Statistical kind of these models renders them impractical for simulation of the individual storm. Therefore one has to correct the empirical models using various additional speculations. The influence of magnetospheric inputs such as distributions of electric potential, number and energy fluxes of the precipitating electrons on the results of the ionospheric storm simulations has been investigated in this work. With this aim for the strong geomagnetic storm on September 25, 1998 hour global distributions of those magnetospheric inputs from 20 to 27 September were calculated by the magnetogram inversion technique (MIT). Then with the help of 3-D ionospheric model two variants of ionospheric response to this magnetic storm were simulated using MIT data and empirical models of the electric fields (Sojka et al., 1986) and electron precipitations (Hardy et al., 1985). The comparison of the received results showed that for high-latitude and subauroral stations the daily variations of electron density calculated with MIT data are more close to observations than those of empirical models. In addition using of the MIT data allows revealing some peculiarities in the daily variations of electron density during strong geomagnetic storm. References Sojka J.J., Rasmussen C.E., Schunk R.W.

    2016-09-01

    Full Text Available SUMMARY Objective: Uncus is the hook-like most anteromedial portion of the parahippocampal gyrus and is a part of the limbic system. It is the only gyrus, together with the amygdala, that contains nuclei and is associated with seizures accompanied by olfactory hallucinations. The aim of this study is to examine the relationship between different uncus lesions detected by magnetic resonance imaging (MRI and epilepsy/seizures. Method: 33 patients with unilateral or bilateral uncus lesions on MRI obtained between March 2008 through May 2014 were enrolled in the study. MR images and clinical charts of patients were retrospectively investigated for MRI findings and presence of epilepsy/seizures. Results: Bilateral uncus involvement was observed in herpes encephalitis (n=5, autoimmune limbic encephalitis (n=2, mesial temporal sclerosis (n=3, metastasis (n=1 and Rasmussen encephalitis (n=1, whereas unilateral involvement of the uncus was seen in glial tumors (n=4, metastases (n=4, mesial temporal sclerosis (n=4, cavernous angioma (n=2, dysembryoplastic neuroepithelial tumor (DNET, n=5, herpes encephalitis (n=1, and autoimmune limbic encephalitis (n=1. Epilepsy/seizures were present in two-thirds of patients. However, none of the 5 patients with a metastatic uncus lesion showed epilepsy/seizures. Conclusions: Many uncus pathologies can be detected by MRI and most of them are associated with epilepsy. Keywords: Epilepsy, Hippocampus; Magnetic resonance imaging; Uncus; Uncinate gyrus

  17. Effect of different approaches to decouple the dependence of nuclei-liquid surface energy on size and temperature

    Directory of Open Access Journals (Sweden)

    Mara Cristina Freitas

    2009-03-01

    Full Text Available Tests involving the Classical Nucleation Theory (CNT often disregard the size dependence of surface energy. Thus, the surface energy of critical nuclei is assumed to be a macroscopic quantity that depends only on the temperature of a flat surface. However, because the size of critical nuclei changes with temperature, σcl(T should be described as a function of both temperature and size of critical nuclei. The present work examines the temperature dependence of macroscopic surface energy, decoupling it from the size dependent part. Tolman, Rasmussen and Vogelsberger's equations are used to decouple the dependence of surface energy on size, using experimental data for the following silicate glasses Li2O.2SiO2 (LS2 and Na2O.2CaO.3SiO2 (N1C2S3. These equations are successful in obtaining a decrease in σcl(T, in agreement with theoretical predictions. For all the values of δ , Tolman's equation produces the lowest values of σcl(T. Nevertheless, they are very close to the liquid/vapor surface energy (σlv, which contradicts the Stefan's rule (i.e. σcl/σ lv << 1. Therefore, it is demonstrated that the assumption of the curvature dependence of surface energy does not suffice, per se, to explain the discrepancy between the experimental and theoretical values of nucleation rates.

  18. 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

    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 report is on the observation of zinc-assisted enhancement in magnetoelectric (ME) coupling in cobalt zinc ferrite, Co(1-x)ZnxFe2O4(x=0-0.5) (CZFO)-lead zirconate titanate (PZT) composites. In such ferromagnetic-piezoelectric composites, an applied ac magnetic field produces dynamic deformation in ferrites due to magnetostriction and results in an induced electric field due to piezoelectric effect in PZT [1]. Important findings are as follows. (i) Bulk samples of pure CFO and PZT prepared either by traditional ceramic processing or by microwave sintering show very weak ME coupling. (iii) Enhancement in ME coupling, by a factor of five, is observed in a layered structure of thick films of CFO and PZT. (iv) Substitution of Zn in CFO is observed to strengthen magneto-mechanical and ME couplings in multilayers. (v) The interface coupling parameter, obtained from our theoretical model [2], shows an increase with x and a peak value for x=0.4. --- Research supported by a grant from the NSF (DMR-0072144) 1. G.

    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

    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.

    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

    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.

  11. Development of AI (Artificial Intelligence)-based simulation system for man-machine system behavior in accidental situations of nuclear power plant

    International Nuclear Information System (INIS)

    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)

    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.

  14. 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

    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

  17. Fifty Years of THERP and Human Reliability Analysis

    Energy Technology Data Exchange (ETDEWEB)

    Ronald L. Boring

    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.

  18. Waste Feed Delivery System Phase 1 Preliminary RAM Analysis [SEC 1 and 2

    2000-10-11

    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&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.

  19. Logarithmic minimal models with Robin boundary conditions

    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.

    2015-01-01

    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.

    1997-12-31

    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.

    Purpose: Elucidating the potential contribution of specific autoantibodies (Ab's) to the etiology and/or pathology of some human epilepsies. Methods: Six epilepsy patients with Rasmussen's encephalitis (RE) and 71 patients with other epilepsies were tested for Ab's to the –B— peptide (amino acids 372-395) of the glutamate/AMPA subtype 3 receptor (GluR3B peptide), double-stranded DNA (dsDNA), and additional autoimmune disease-associated autoantigens, and for the ability of their serum and cerebrospinal-fluid (CSF) to kill neurons. Results: Elevated anti-GluR3B Ab's were found in serum and CSF of most RE patients, and in serum of 17/71 (24%) patients with other epilepsies. In two RE patients, anti-GluR3B Ab's decreased drastically in CSF following functional-hemispherotomy, in association with seizure cessation and neurological improvement. Serum and CSF of two RE patients, and serum of 12/71 (17%) patients with other epilepsies, contained elevated anti-dsDNA Ab's, the hallmark of systemic-lupus-erythematosus. The sera (but not the CSF) of some RE patients contained also clinically elevated levels of –classical— autoimmune Ab's to glutamic-acid-decarboxylase, cardiolipin, β2-glycoprotein-I and nuclear-antigens SS-A and RNP-70. Sera and CSF of some RE patients caused substantial death of hippocampal neurons. Conclusions: Some epilepsy patients harbor Ab's to GluR3 and dsDNA on both sides of the blood-brain barrier, and additional autoimmune Ab's only in serum. Since all these Ab's may be detrimental to the nervous system and/or peripheral organs, we recommend testing for their presence in epilepsy, and silencing their activity in Ab-positive patients.

In two RE patients, anti-GluR3B Ab's decreased drastically in CSF following functional-hemispherotomy, in association with seizure cessation and neurological improvement. Serum and CSF of two RE patients, and serum of 12/71 (17% patients with other epilepsies, contained elevated anti-dsDNA Ab's, the hallmark of systemic-lupus-erythematosus. The sera (but not the CSF of some RE patients contained also clinically elevated levels of –classical— autoimmune Ab's to glutamic-acid-decarboxylase, cardiolipin, β2-glycoprotein-I and nuclear-antigens SS-A and RNP-70. Sera and CSF of some RE patients caused substantial death of hippocampal neurons. Conclusions: Some epilepsy patients harbor Ab's to GluR3 and dsDNA on both sides of the blood-brain barrier, and additional autoimmune Ab's only in serum. Since all these Ab's may be detrimental to the nervous system and/or peripheral organs, we recommend testing for their presence in epilepsy, and silencing their activity in Ab-positive patients.

  5. 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.

The number varies depending on the screening tool amended and clinical setting. A large number of these patients are undernourished when admitted to the hospital, and in most of these patients, undernutrition develops further during hospital stay. The nutrition course of the patient starts by nutritional screening and is linked to the prescription of a nutrition plan and monitoring. The purpose of nutritional screening is to predict the probability of a better or worse outcome due to nutritional factors and whether nutritional treatment is likely to influence this. Most screening tools address four basic questions: recent weight loss, recent food intake, current body mass index, and disease severity. Some screening tools, moreover, include other measurements for predicting the risk of malnutrition. The usefulness of screening methods recommended is based on the aspects of predictive validity, content validity, reliability, and practicability. Various tools are recommended depending on the setting, ie, in the community, in the hospital, and among elderly in institutions. The Nutrition Risk Screening (NRS 2002 seems to be the best validated screening tool, in terms of predictive validity ie, the clinical outcome improves when patients identified to be at risk are treated. For adult patients in hospital, thus, the NRS 2002 is recommended.Keywords: nutritional risk screening

  7. Combining cognitive engineering and information fusion architectures to build effective joint systems

    The Dual Node Decision Wheels (DNDW) architecture concept was previously described as a novel approach toward integrating analytic and decision-making processes in joint human/automation systems in highly complex sociotechnical settings. In this paper, we extend the DNDW construct with a description of components in this framework, combining structures of the Dual Node Network (DNN) for Information Fusion and Resource Management with extensions on Rasmussen's Decision Ladder (DL) to provide guidance on constructing information systems that better serve decision-making support requirements. The DNN takes a component-centered approach to system design, decomposing each asset in terms of data inputs and outputs according to their roles and interactions in a fusion network. However, to ensure relevancy to and organizational fitment within command and control (C2) processes, principles from cognitive systems engineering emphasize that system design must take a human-centered systems view, integrating information needs and decision making requirements to drive the architecture design and capabilities of network assets. In the current work, we present an approach for structuring and assessing DNDW systems that uses a unique hybrid DNN top-down system design with a human-centered process design, combining DNN node decomposition with artifacts from cognitive analysis (i.e., system abstraction decomposition models, decision ladders) to provide work domain and task-level insights at different levels in an example intelligence, surveillance, and reconnaissance (ISR) system setting. This DNDW structure will ensure not only that the information fusion technologies and processes are structured effectively, but that the resulting information products will align with the requirements of human decision makers and be adaptable to different work settings .

  8. A serpin-induced extensive proteolytic susceptibility of urokinase-type plasminogen activator implicates distortion of the proteinase substrate-binding pocket and oxyanion hole in the serpin inhibitory mechanism.

    The formation of stable complexes between serpins and their target serine proteinases indicates formation of an ester bond between the proteinase active-site serine and the serpin P1 residue [Egelund, R., Rodenburg, K.W., Andreasen, P.A., Rasmussen, M.S., Guldberg, R.E. & Petersen, T.E. (1998) Biochemistry 37, 6375-6379]. An important question concerning serpin inhibition is the contrast between the stability of the ester bond in the complex and the rapid hydrolysis of the acyl-enzyme intermediate in general serine proteinase-catalysed peptide bond hydrolysis. To answer this question, we used limited proteolysis to detect conformational differences between free urokinase-type plasminogen activator (uPA) and uPA in complex with plasminogen activator inhibitor-1 (PAI-1). Whereas the catalytic domain of free uPA, pro-uPA, uPA in complex with non-serpin inhibitors and anhydro-uPA in a non-covalent complex with PAI-1 was resistant to proteolysis, the catalytic domain of PAI-1-complexed uPA was susceptible to proteolysis. The cleavage sites for four different proteinases were localized in specific areas of the C-terminal beta-barrel of the catalytic domain of uPA, providing evidence that the serpin inhibitory mechanism involves a serpin-induced massive rearrangement of the proteinase active site, including the specificity pocket, the oxyanion hole, and main-chain binding area, rendering the proteinase unable to complete the normal hydrolysis of the acyl-enzyme intermediate. The distorted region includes the so-called activation domain, also known to change conformation on zymogen activation.

    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).

  11. 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

  12. 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

    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

    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

    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)

    The North Atlantic INTIMATE (INtegration of Ice-core, MArine and TErrestrial records) group has previously recommended an Event Stratigraphy approach for the synchronisation of records of the Last Termination using the Greenland ice core records as the regional stratotypes. A key element of these protocols has been the formal definition of numbered Greenland Stadials (GS) and Greenland Interstadials (GI) within the past glacial period as the Greenland expressions of the characteristic Dansgaard-Oeschger events that represent cold and warm phases of the North Atlantic region, respectively. Using a recent synchronization of the NGRIP, GRIP, and GISP2 ice cores that allows the parallel analysis of all three records on a common time scale, we here present an extension of the GS/GI stratigraphic template to the entire glacial period. In addition to the well-known sequence of Dansgaard-Oeschger events that were first defined and numbered in the ice core records more than two decades ago, a number of short-lived climatic oscillations have been identified in the three synchronized records. Some of these events have been observed in other studies, but we here propose a consistent scheme for discriminating and naming all the significant climatic events of the last glacial period that are represented in the Greenland ice cores. In addition to presenting the updated event stratigraphy, we make a series of recommendations on how to refer to these periods in a way that promotes unambiguous comparison and correlation between different proxy records, providing a more secure basis for investigating the dynamics and fundamental causes of these climatic perturbations.

We examined whether previous hospitalizations were independently associated with mortality among patients with COPD ventilated for the first time. Patients and methods: In the Danish National Patient Registry, we established a cohort of patients with COPD ventilated for the first time from 2003 to 2011 and previously medicated for obstructive airway diseases. We assessed the number of hospitalizations for COPD in the preceding year, age, sex, comorbidity, mode of ventilation, survival to discharge, and days to death beyond discharge. Results: The cohort consisted of 6,656 patients of whom 66% had not been hospitalized for COPD in the previous year, 18% once, 8% twice, and 9% thrice or more. In-hospital mortality was 45%, and of the patients alive at discharge, 11% died within a month and 39% within a year. In multivariate models, adjusted for age, sex, mode of ventilation, and comorbidity, odds ratios for in-hospital death were 1.26 (95% confidence interval [CI]: 1.11–1.44, 1.43 (95% CI: 1.19–1.72, and 1.56 (95% CI: 1.30–1.87 with one, two, and three or more hospitalizations, respectively. Hazard ratios for death after discharge from hospital were 1.32 (95% CI: 1.19–1.46, 1.76 (95% CI: 1.52–2.02, and 2.07 (95% CI: 1.80–2.38 with one, two, and three or more hospitalizations, respectively.

    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

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%. The estimated completeness was 43% (95% CI: 38%–49% for the DNPR and 75% (95% CI: 70%–79% for Astraia. Conclusion: Almost all live-born children were scanned during the second trimester in Denmark. However, low completeness may hamper the use of the DNPR for studies of prenatally detected

Methods: We did a nationwide population-based cohort study in Danish PLHIV to evaluate the association between smoking status and 1 overall renal function and risk of chronic kidney disease (CKD, 2 risk of any renal replacement therapy (aRRT, and 3 mortality following aRRT. We calculated estimated creatinine clearance using the Cockcroft–Gault equation (CG-CrCl, and evaluated renal function graphically. We calculated cumulative incidence of CKD (defined as two consecutive CG-CrCls of ≤60 mL/min, ≥3 months apart and aRRT and used Cox regression models to calculate incidence rate ratios (IRRs for risk of CKD, aRRT, and mortality rate ratios (MRRs following aRRT. Results: From the Danish HIV Cohort Study, we identified 1,475 never smokers, 768 previous smokers, and 2,272 current smokers. During study period, we observed no association of smoking status with overall renal function. Previous and current smoking was not associated with increased risk of CKD (adjusted IRR: 1.1, 95% confidence interval [CI]: 0.7–1.7; adjusted IRR: 1.3, 95% CI: 0.9–1.8 or aRRT (adjusted IRR: 0.8, 95% CI: 0.4–1.7; adjusted IRR: 0.9, 95% CI: 0.5–1.7. Mortality following aRRT was high in PLHIV and increased in smokers vs never smokers (adjusted MRR: 3

    NASA space systems, including mission operations on the ground and in space, are complex, dynamic, predominantly automated systems in which the human operator is a supervisory controller. Models of cognitive functions in complex systems are needed to describe human performance and form the theoretical basis of operator workstation design, including displays, controls, and decision aids. Currently, there several candidate modeling methodologies. They include the Rasmussen abstraction/aggregation hierarchy and decision ladder, the goal-means network, the problem behavior graph, and the operator function model. The research conducted under the sponsorship of this grant focuses on the extension of the theoretical structure of the operator function model and its application to NASA Johnson mission operations and space station applications. The initial portion of this research consists of two parts. The first is a series of technical exchanges between NASA Johnson and Georgia Tech researchers. The purpose is to identify candidate applications for the current operator function model; prospects include mission operations and the Data Management System Testbed. The second portion will address extensions of the operator function model to tailor it to the specific needs of Johnson applications. At this point, we have accomplished two things. During a series of conversations with JSC researchers, we have defined the technical goal of the research supported by this grant to be the structural definition of the operator function model and its computer implementation, OFMspert. Both the OFM and OFMspert have matured to the point that they require infrastructure to facilitate use by researchers not involved in the evolution of the tools. The second accomplishment this year was the identification of the Payload Deployment and Retrieval System (PDRS) as a candidate system for the case study.

    The prominent philosopher, theologian, physician, musicologist and organ soloist Albert Schweitzer (14. 1. 1875-4. 9. 1965) submitted his MD thesis Kritik der von medizinischer Seite veröffentlichten Pathographien uber Jesus (Criticism of the medical pathographies on Jesus) in 1913. Very soon he published this work under the title Die psychiatrische Beurteilung Jesu. Darstellung und Kritik (The psychiatric evaluation of Jesus. Description and criticism) in order to reach a broader audience. Schweitzer's explicit motive for selecting this topic was to influence the theological debate by means of a M. D. thesis on psychiatric pathographies on Jesus. He was confronted with a lot of reproaches. These reproaches contended that his theological opinions had been supporting tendencies to describe Jesus as a mentally ill person or a religious fanatic. In addition, some authors of pathographies on Jesus (De Loosten, Binet-Sanglé, Hirsch, Rasmussen) characterized Jesus as mentally ill, suffering from paranoia. Schweitzer intended to reject the reproaches considering himself and the postulates of the authors of the pathographies. Schweitzer combined in a transdisciplinary way theological, psychiatric and psychopathological arguments. He did this in a very convincing way. Although Schweitzer did not deal with a central or explicit psychiatric question, he implicitly postulated transdisciplinary approaches for proper retrospective pathographies on historic persons. At the age of thirty, Schweitzer decided to finish his academic career and to begin studies in medicine as a preparation for work as a physician in Africa. This decision provoked much lack of understanding in his personal environment. Therefore it may be possible that a very personal motive contributed to the selection of the topic of the MD thesis. Among psychiatric authorities, Albert Schweitzer's interest in the criticisms of psychiatric pathographies and his transdisciplinary approach to this topic encountered

  7. 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

    Permafrost peatbanks along the West Antarctic Peninsula (WAP) have become valuable high-resolution archives for late-Holocene climatic conditions recently. We recently observed and studied a few water-saturated peatlands that had formed in rocky depressions near Vernadsky Station and in mainland Antarctica (~ 65°S, 64°W). Remarkably, we seem to be the very first ones to analyze these systems for environmental reconstructions. The similarity between these peatlands and fens from the lower latitudes is striking, and the rarity of these systems along the WAP is intriguing. We present a high-resolution, multi-proxy record of ecosystem development and paleoenvironmental conditions for Rasmussen peatland. The ecosystem is ~100 m2 in size and is characterized by a shallow water table depth at 7 cm below the surface. Surface vegetation is dominated by Calliergon spp., a wet-adapted moss found along the WAP. The studied moss deposit is 50 cm thick and has a high organic matter content (> 90% dry weight). Plant macrofossil analysis reveals that the peatland was initially a wet Sanionia spp. carpet and that a sharp transition to Calliergon spp. occurred about half way through the deposit. A distinct layer of highly decomposed organic matter was observed from 32 to 40 cm and could indicate a period of slowed peat formation, potentially due to dry conditions (enhanced peat decay) or perennial snow cover (limited plant growth). Biochemical decomposition indicators such as carbohydrate yields, acid:aldehyde ratios of lignin phenols, and hydroxyproline yields are being determined to better understand the extent of peat decay that has occurred at this site throughout its development, particularly to further address the nature of the observed stratigraphic changes. Preliminary results indicate that carbohydrate yields of the bottom half of the core are about 1/3 smaller than those of the top half, indicating substantial carbon loss due to decomposition. Overall, these peatlands

    Objective To investigate the effect of functional hemispherectomy on intractable epilepsy with hemiparalysis. Methods From April 2002 to December 2007, 8 epileptic patients with hemisphere atrophy received functional hemispherectomy in 6 hospitals. Scalp and video EEG examinations revealed epileptic waves in all the patients, including 7 in the ipsilateral side and 1 in the contralateral side. Magnetic resonance imaging (MRI) indicated hemisphere atrophy and ventriculomegaly in all the patients. Risk factors for epilepsy were found in all the patients, including 3 with hyperpyrexia, 2 with spontaneous intracranial hemorrhage, 2 with traumatic brain injury, and 1 with viral encephalitis (also suspected of Rasmussen's encephalitis). Hemispberectomy was performed based on the methods of Rasmussen and Schramm. Results All the patients were followed up postoperatively for 8 months to 6.4 years (mean 2.8 years). Satisfactory outcomes (including disappearance of seizures) were achieved in 6 patients, but 1 of them experienced seizure reoccurrence because of personal withdraw of antiepileptic drugs 2 years after total seizure relief, and was successfully managed by administration of another two antiepileptic drugs. Significant improvement was achieved in the other case, in which the seizure frequency was reduced by over 70%. The postoperative dose or number of the antiepileptic drugs was reduced in 6 patients, and 2 patients no longer required any medication. No death or serious complications occurred in these patients except for 1 patient who suffered acute status epilepticns perioperatively and was successfully managed. Postoperative EEG revealed the absence of epileptic waves in 6 patients. Two patients showed epileptic waves on the contralateral side. Paralysis aggravation was not observed in 7 patients, and 1 patient experienced temporal muscle weakness, which recovered gradually. Six patients showed improved limb functions, but the thumb function failed to recover

    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.

  12. Magnetotelluric investigation of the Toender area, Denmark. ALTKUL project report part 2

    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

    Full Text Available The period 1976-2002 can be regarded as the first phase of renewable energy and conservation (REC development, as the REC technologies were still a supplement to energy systems mainly based upon fossil fuels (here named FFU technologies. In this first phase of the Danish development, a ”Green energy cluster” consisting of renewable energy technologies such as wind power, solar energy, and biomass and energy conservation technologies was developed. This development was implemented despite a systematic resistance from the Ministry of Finance, the industrial establishment and the established fossil fuel-based power companies, which regarded the new “Green energy technologies” as competitors to their large power plants based upon coal and oil. Independent lobbyists such as energy grass roots organisations, new companies within the green technology cluster and some active politicians were able to give political momentum to a development of a spectrum of green energy technologies. This process of organisations independent of existing economic interests being given democratic influence is here defined as the innovative democracy process. In the period 2000-2013, Denmark entered a second phase with REC technologies substantially increasing their share of the energy supply and on their way of becoming the main energy technologies. 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.

    anomalies. We suggest that the latitudinal δ18O gradient during the glacial is result of 1) relatively higher degree of precipitation with a Pacific signature at NGRIP, 2) increased summer bias at Summit, and 3) enhanced Raleigh distillation process due to and increased source-to-site distance, and we conclude that this is governed by North American Ice Sheet (NAIS) volume and North Atlantic sea-ice extent and/or sea-surface temperatures (SST) at orbital timescales, while changing sea-ice extent and SSTs are the driving mechanisms on shorter timescales. We assert that δ18O difference maxima can be linked to Heinrich Events, which is associated with southwards expansion of polar waters and low SSTs in the North Atlantic, and ths propose a direct link between the marine realm and the Greenland ice core records.

    背景:Schazker Ⅴ、Ⅵ型骨折常造成交叉韧带、侧副韧带及半月板等部位的损伤,且塌陷移位严重,若仅采用一侧锁定钢板,则较难支撑及满意复位。目的:比较双切口双钢板内固定与膝前正中切口锁定钢板内固定修复Schatzker Ⅴ、Ⅵ型胫骨平台骨折后的效果及稳定性评价。方法:纳入76例Schazker Ⅴ、Ⅵ型胫骨平台骨折患者,分别采用锁定钢板内固定(n=38)和双切口双钢板内固定(n=38)进行治疗,通过X射线正、侧位片评估骨折复位及愈合情况,并对胫骨平台内翻角、胫骨平台内侧后倾角进行生物力学测试。结果与结论:双切口双钢板内固定组住院时间、内固定后开始负重时间显著少于锁定钢板内固定组(P0.05);关节强直、骨折延迟愈合、针道感染、骨折延迟愈合、膝内翻畸形多项并发症比较,双切口双钢板内固定组显著少于锁定钢板内固定组,差异均有显著性意义(P 0.05);双切口双钢板内固定组内固定后Rasmussen分级明显优于锁定钢板内固定组,差异均有显著性意义(P0.05). 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.

    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

    Full Text Available The period 1976-2002 can be regarded as the  first phase of renewable energy and conservation (REC development, as the REC technologies were still a supplement to energy systems mainly based upon fossil fuels  (here named FFU technologies.  In this first phase  of the Danish development, a ”Green energy cluster” consisting of renewable energy technologies such as wind power, solar energy, and biomass  and energy conservation technologies was developed. This development was implemented despite a systematic resistance from the Ministry of Finance, the industrial establishment and the established fossil fuel-based power companies, which regarded the new  “Green energy technologies” as competitors to their large power plants based upon coal and oil. Independent lobbyists such as energy grass roots organisations, new companies within the green technology cluster and some active politicians were able to give political momentum to a development of a spectrum of green energy technologies. This process of organisations independent of existing economic interests being given democratic influence is here defined as the innovative democracy process. In the period 2000-2013, Denmark entered a second phase with REC technologies substantially increasing their share of the energy supply and on their way of  becoming the main energy technologies. 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

  1. Effects of hydrophilic macropore fillings and coatings on the infiltration into water repellent porous media

    2012-12-01

    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

  2. Upper Cenozoic deposits of the central Delmarva Peninsula, Maryland and Delaware

    The surface and shallow subsurface sediments of the lower Delmarva Peninsula include beds ranging in age from Miocene to Holocene. The oldest beds appear to be typical shelf deposits of the Chesapeake Group (Calvert-Choptank age). These marine units are overlain by deltaic deposits, which range from fluviatile facies in the north (Pensauken Formation) to marginal marine and marine beds in the south ('Yorktown(?) and Cohansey(?)' Formations as used by Rasmussen and Slaughter in 1955). This large deltaic mass underlies most of the Delmarva Peninsula. Fossil age determinations supplemented by some radiometric dates indicate the delta to be largely late Miocene in age. The nonmarine facies of the delta, the Pensauken Formation, previously was considered to be Pleistocene in age. The late Miocene delta and possibly the Yorktown Formation (lower to middle Pliocene) are overlain by a feldspathic sand, the Beaverdam, which is at least in part marginal marine. Microflora recovered from this formation include species no longer indigenous to the Delmarva region ('exotics'). On the basis of existing information, microfloral assemblages containing 'exotics' are pre-Pleistocene in age. The Beaverdam therefore is pre-Pleistocene in age, probably late Pliocene. A highly dissected and weathered unit, the Walston Silt, caps the uplands of the central Delmarva Peninsula, where it overlies the Beaverdam. The Walston has a microflora containing 'exotics' and therefore is considered to be the youngest Tertiary unit (uppermost Pliocene) in this area. Sediments forming a barrier-back-barrier sequence fringe most of the southern Maryland-Delaware part of the Delmarva Peninsula and are found at altitudes of as much as 15 m (50 ft) above sea level. This sequence, the Omar Formation, is Sangamon in age and has been dated radiometrically as 60,000 to about 100,000 years old. The microflora in these beds contains no 'exotics,' and the assemblage suggests a warm-temperate environment. The Omar

    '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

    The sky islands of the southwestern U.S. offer a unique opportunity to study the coevolution of landscape processes in areas of similar rock type and tectonic history but a wide range of climates. In this study we compile high-resolution, spatially-distributed data for the available energy to drive rock weathering and other landscape processes, i.e. the Effective Energy and Mass Transfer (EEMT) variable of Rasmussen and Tabor (2005), together with data for LiDAR-derived above-ground biomass, soil thickness, water storage potential, hillslope relief, and valley density in the Santa Catalina and Pinaleno Mountains, two predominantly granitic ranges in southern Arizona. Strong correlations exist among these variables such that warm, dry, low elevation portions of these areas are characterized by low biomass, thin soils, low water-storage potential, steep slopes, and high valley densities. Cooler, wetter, higher-elevation portions have systematically higher biomass, thicker soils, higher water-storage potential, gentler slopes, and lower valley densities. Moreover, all of these variables have a nonlinear dependence on climate/elevation. Slope gradient and aspect also exert an important control on these variables, with steep, south-facing hillslopes characterized by drier-than-average conditions for a given elevation and north-facing slopes associated with wetter-than-average conditions. We hypothesize that these correlations partly reflect coevolutionary positive-feedback mechanisms among these processes that amplify differences in rates set by climate, tectonics, and rock type. For example, thicker soils with higher water storage potential that form at higher elevations/north-facing slopes tend to have greater biomass, causing lower runoff ratios, lower rates of slopewash and fluvial erosion, and increased rates of colluvial transport, thereby promoting thicker soils, lower-gradient slopes, and lower valley densities. Thicker soils and higher water storage potentials

  7. 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

    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.

    Since the mid-1980s, the Oregon Department of Fish and Wildlife (ODFW) has been participating in the Bonneville Power Administration's (BPA's) efforts to mitigate for the negative impacts to fish and wildlife resulting from the development and operation of the 7 Columbia Basin Federal Hydropower System. BPA's mitigation obligations were formally recognized and mandated by the Northwest Power Act of 1980 and are guided by the Northwest Power Planning Council's (NWPPC's) Columbia Basin Fish and Wildlife Program. BPA funds fish and wildlife projects throughout the Basin to meet the habitat and population restorative goals and objectives outlined in the NWPPC's Fish and Wildlife Program and to fulfill its mitigation responsibilities under the Power Act. Impacts to wildlife resulting from hydrofacility construction/inundation were estimated using Habitat Evaluation Procedures (HEP) in the mid and late 1980s and are documented in BPA' s Wildlife Loss Assessments (Rasmussen and Wright 1990,a,b,c,d) and in the U.S. Army Corps of Engineers Lower Snake River Wildlife Habitat Compensation Evaluation (ACOE 1991). The loss assessments provided estimates of lost habitat quality and quantity for the target species selected to represent the habitat cover types impacted by hydropower construction/inundation. The NWPPC incorporated these losses into their Fish and Wildlife Program, recognizing them as the unannualized losses attributable to the construction/inundation of the federal hydropower system (NWPPC 1995 and 2000, Table 1 1-4). The HEP methodology is used by wildlife managers within the Columbia Basin to determine habitat values, expressed as Habitat Units, gained through BPA-funded mitigation project work.

    BACKGROUND:Single fracture or colapse of the posterolateral tibial plateau fractures is relatively rare in the clinical work. Rational choice of surgical approach and internal fixation for posterolateral plateau fracture is significant to restore the lower limb force line, maintain the joint stability and obtain good biocompatibility. OBJECTIVE:To compare the stability and biocompatibility of Carlson posterolateral and posterior midline approaches for the treatment of posterolateral tibial plateau fractures with “T” shaped locking plate. METHODS:From July 2011 to July 2014, 43 patients with posterolateral tibial plateau fractures, who were treated in the Affiliated Hospital of Jining Medical University, were retrospectively analyzed. Al patients were assigned to two groups according to approaches. In the Carlson posterolateral approach group, 22 cases received “T”-shaped plate insertion by Carlson posterolateral approach. In the posterior midline approach group, 21 cases received “T”-shaped plate insertion by posterior midline approach. After repair, perioperative data, fixation effects and knee function score were compared and analyzed between both groups. RESULTS AND CONCLUSION:(1) 43 cases (43 knees) of posterolateral tibial plateau fractures were folowed up strictly. (2) No significant difference in operation time, fracture healing time, total load time, Hospital for Special Surgery score at 12 months postoperatively, tibial plateau angle and posterior slope angle immediately and 12 months postoperatively was detected between both groups (P > 0.05). (3) Significant differences in fracture exposure, blood loss, and excelent and good rate of Rasmussen at 12 months postoperatively were identified in both groups. Moreover, above indexes were better in the Carlson posterolateral approach group than in the posterior midline approach group (P  目的:比较 Carlson 后外侧和后正中两种入路置入“T”形锁定钢板修复胫骨平台后外

    with the bulk loess median grain size (D50bulk) that is considered an integrated proxy of wind strength, dust source distance, aridity and vegetation cover. While an increase of dust flux and D50bulk with time is apparent, such a trend cannot be seen in the quartz grain size measures (D50quartz). This observation may imply that wind speeds were relatively constant in the studied time interval, while the turbulence of the flow may have been extremely varying (i.e. strong/rapid changes in the frequency/magnitude of dust storm events). A striking feature of the MAR record is that accumulation minima in the Dunaszekcsö record are synchronous with the Greenland Interstadials (GI-5.1 to GI-3). Subsequent Ca2+ minima in the NGRIP record at 26.22 and 25.02 ka (b2k) are also coeval with the MAR minima in the studied loess sequence. At the same time, these patterns are barely visible in the bulk and quartz grain size records. We speculate that the synchronous changes in the NGRIP Ca2+ and the Dunaszekcsö MAR records are results of millennial scale variations in the activity of Northern Hemisphere dust emitting regions shown in two archives from different environments. The very similar timing of MAR minima (and also some of the maxima) suggest a rapid aeolian system response in East Central Europe to abrupt climatic changes in the North Atlantic. Although such a synchronicity does not prove a Central European dust source to Greenland, it is consistent with this possibility.

    In an attempt to make the main results from the Congress on Climate Change: Global Risk, Challenges and Decisions available to the public as early as possible, the steering committee decided to publish all talks and posters presented at the Congress in this unique collection of abstracts, in time for the conference Further to the abstract collection the Congress will publish two more products in the near future as described in the following; a synthesis report with the main conclusions, and a book aimed at an academic audience 1 Two Products from the Congress Two products are being produced based on the presentations and discussions at the Congress The first product will be a synthesis report of the main conclusions from the Congress The synthesis report will be ready in June 2009 The synthesis has the purpose of explaining the current state of understanding man-made climate change and what we can do about it to the non-scientist, ie politicians, media and interested citizens The synthesis will build on the messages presented to the Danish Prime Minister, Mr Anders Fogh Rasmussen, host of the COP15, at the closing session of the Congress These six messages were drafted by the Writing Team (see below) based on input from the session chairs and a reading of the 1600+ abstracts submitted to the Congress The second product is a book aimed at an academic audience The book will include more detailed scientific results from all of the sessions and will be published by Cambridge University Press in 2010 It will be an extension and elaboration of the synthesis report Who's writing the Synthesis Report and the Book? A Writing Team consisting of 12 internationally respected scientists from all continents is responsible for developing both products When the synthesis report has been drafted by the Writing Team, it will be discussed in the Scientific Steering Committee of the Congress and reviewed by the Earth System Science Partnership (ESSP) and a group of experts identified
