    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.)

    2017-03-01

    This paper describes three applications of Rasmussen's idea to systems engineering practice. The first is the application of the abstraction hierarchy to engineering specifications, particularly requirements specification. The second is the use of Rasmussen's ideas in safety modeling and analysis to create a new, more powerful type of accident causation model that extends traditional models to better handle human-operated, software-intensive, sociotechnical systems. Because this new model has a formal, mathematical foundation built on systems theory (as was Rasmussen's original model), new modeling and analysis tools become possible. The third application is to engineering hazard analysis. Engineers have traditionally either omitted human from consideration in system hazard analysis or have treated them rather superficially, for example, that they behave randomly. Applying Rasmussen's model of human error to a powerful new hazard analysis technique allows human behavior to be included in engineering hazard analysis.

    2014-07-01

    Full Text Available This article focuses on the portrayal of reindeer Sami in the Danish explorer Knud Rasmussen's early book Lapland from 1907, a work that has received relatively little attention in Rasmussen scholarship. His characterizations of the Sami reflect conventional, paternalistic ideas of race and culture at the turn of the century as well as romantic-sentimental conceptions of indigenous peoples as noble savages. Rasmussen is a lively storyteller, however, and the immediacy and vividness of his depictions simultaneously open up for perspectives that, at least partly, serve to undermine traditional stereotypes. If read closely, Rasmussen's narrative evinces clear tensions between its conventional generalizations about the reindeer Sami as an indigenous people and the direct, phenomenological descriptions that are the products of Rasmussen's actual encounter with them. At the same time his instinctive sympathy for the Sami is enlarged by his own, deeply personal yearning for a life style and culture grounded in Northern cold and winter, which he encountered growing up in Greenland and which runs like a leitmotif through all his writing.

We studied 5 patients with Rasmussen's encephalitis, assessing clinical history and MR images. All patients had refractory focal seizures with a predominant motor component associated with hemispheric atrophy, that was proportional to severity of disease and neurological deficits in these patients. Gray and white matter abnormal signal on T2 MR images were found in patients who had hemiparesis. It was not related to the duration of the disease but to aggressiveness. MR proton spectroscopy in severe disease showed lactate and choline increase and decreased NAA, reflecting neuronal and axonal loss, gliosis and elevated membrane turnover and recent - crisis (not controlled.

    Theodore Brown Rasmussen succeeded Wilder Penfield as director of the Montreal Neurological Institute (MNI) and held this post from 1960 to 1972. During his career, Rasmussen probably performed more operations for epilepsy than any other surgeon of his time; he became the foremost authority in this field. His meticulous follow-up analyses of the MNI seizure series provided substantial evidence for the success of surgery in the treatment of focal epilepsy. In addition, he made significant contributions to surgery of the pituitary gland for control of cancer, treatment of cerebral and spinal tumors, application of the intracarotid Amytal test for lateralization of speech and memory function, and characterization and treatment of epilepsy accompanied by chronic encephalitis, now referred to as Rasmussen syndrome. His painstaking attention to surgical details as well as his insistence on close monitoring of patient care and critical scrutiny of clinical results marked him as an outstanding teacher and role model for young neurosurgeons and neuroscientists.

    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.

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)

  5. Rasmussen's encephalitis: the relevance of neuropsychological assessment in patient's treatment and follow up

    2002-01-01

    Full Text Available Rasmussen's encephalitis is characterized by refractory epilepsy, neurological deterioration and progressive atrophy of one cerebral hemisphere. The objective of this study is to describe the importance of neuropsychological evaluation in the treatment decision and follow-up of patients with Rasmussen´s encephalitis. Neuropsychological assessment was performed in two steps. Firstly, the clinical history was obtained and the Vineland adaptative behavior scale (VABS was applied. After this first step, the patients with social maturity level equal or higher than the inferior limit underwent a battery of neuropsychological assessment. We evaluated three patients before any specific treatment was started, and six months after the intervention (surgery or plasmapheresis. Patient 1 underwent left hemispherectomy and had global improvement on second neuropsychological assessment. This suggests that the decision of performing surgery was adequate. Patients 2 and 3 underwent plasmapheresis. They did not present cognitive decline between both evaluations which suggest that our decision of postponing surgery was adequate as well. We conclude that neuropsychological assessment is important when evaluating patients with Rasmussen´s encephalitis. That is especially true for patients in whom disease progression is slow, and surgery timing has to be carefully planned.

    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.)

    The focus of this manuscript is on cognitive systems engineering/ecological interface design (CSE/EID) and the role that this framework may play in improving system safety. First, the decision making and problem solving literatures are reviewed with an eye towards informational needs that are required to support these activities. The utility of two of Rasmussen's analytical tools (i.e., the abstraction and aggregation hierarchies) in conducting work domain analyses to identify associated information (i.e., categories and relationships) is discussed. The importance of designing ecological displays and interfaces that span the informational categories in the abstraction hierarchy is described and concrete examples are provided. The potential role that ecological interfaces can play in providing effective decision making (i.e., preventing accidents) and problem solving (i.e., dealing with accidents) support, thereby improving the safety of our socio-technical systems, is explored.

    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.

    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).

    Objective To investigate the clinical features and electroencephalogram( EEG) characteristics of Rasmussen encephalitis( encephalitis Rasmussen,RE) in children. Methods The clinical data of 8 children with RE were analyzed retrospec-tively. Results 8 cases of children with an average age of 7 years old and two months in this group were with partial or compre-hensive epilepsy repeated hair as a start,all of the progress of chronic progressive focal epileptic state( EPC) ,with progressive cog-nitive impairment,language dysfunction and hemiplegia. The background activity of VEEG was a slow wave activity in one hemi-sphere or bilateral various guided slow wave activity based on one side hemisphere. The onset interval of VEEG was mostly bilateral hemisphere or unilateral hemisphere dominated by bilateral spinal spikes,spike slow wave,and multiple spike slow wave discharge. Conclusions RE is a kind of epilepsy syndrome with characteristic clinical manifestation and EEG change. And to improve the understanding of the disease is helpful for the early diagnosis.%目的:探讨Rasmussen脑炎( Rasmussen encephalitis,RE)患儿的临床表现和脑电图( EEG)特点。方法回顾性分析8例RE患儿的临床资料。结果本组8例患儿平均发病年龄7岁2月,以反复部分性或全面性癫痫发作起始,均进展为慢性进行性局灶性癫痫持续状态(EPC),伴进行性认知功能障碍、语言功能障碍以及偏瘫。 VEEG背景活动为一侧半球慢波活动或一侧半球为主的双侧各导慢波活动;VEEG发作间期大多为一侧半球或一侧半球为主的双侧各导棘波、棘-慢波、多棘-慢波放电。结论 RE系一种具有特征性的临床表现及脑电图变化的癫痫综合征,提高对该病的认识有助于早期诊断治疗。

    The central thesis of this paper is that Rasmussen framed his approach to Cognitive Systems Engineering from the perspective of a Triadic Semiotic Model. This frame became the context for integrating multiple intellectual threads including Control Theory, Information Theory, Ecological Psychology, and Gestalt Psychology into a coherent theoretical framework. The case is made that the triadic semiotic framework is essential for a complete appreciation of the constructs that were central to Rasmussen's approach: Abstraction Hierarchy, Skill-Rules-Knowledge Model, Ecological Interface Design, and Proactive Risk Management.

  1. Error-associated behaviors and error rates for robotic geology

    Science.gov (United States)

    Anderson, Robert C.; Thomas, Geb; Wagner, Jacob; Glasgow, Justin

    2004-01-01

    This study explores human error as a function of the decision-making process. One of many models for human decision-making is Rasmussen's decision ladder [9]. The decision ladder identifies the multiple tasks and states of knowledge involved in decision-making. The tasks and states of knowledge can be classified by the level of cognitive effort required to make the decision, leading to the skill, rule, and knowledge taxonomy (Rasmussen, 1987). Skill based decisions require the least cognitive effort and knowledge based decisions require the greatest cognitive effort. Errors can occur at any of the cognitive levels.

    Penfield and Rasmussen's homunculus is the valid map of the neural body representation of nearly each textbook of biology, physiology, and neuroscience. The somatosensory homunculus places the foot representation on the mesial surface of the postcentral gyrus followed by the representations of the lower leg and the thigh in superio-lateral direction. However, this strong homuncular organization contradicts the "dermatomal" organization of spinal nerves. We used somatosensory-evoked magnetic fields and source analysis to study the leg's neural representation in the primary somatosensory cortex (SI). We show that the representation of the back of the thigh is located inferior to the foot's representation in SI whereas the front of the thigh is located laterally to the foot's representation. This observation indicates that the localization of the leg in SI rather follows the dermatomal organization of spinal nerves than the typical map of neighboring body parts as depicted in Penfield and Rasmussen's illustration of the somatosensory homunculus.

  17. Glutamic acid decarboxylase autoimmunity in Batten disease and other disorders.

    Degenerative diseases of the CNS, such as stiff-person syndrome (SPS), progressive cerebellar ataxia, and Rasmussen encephalitis, have been characterized by the presence of autoantibodies. Recent findings in individuals with Batten disease and in animal models for the disorder indicate that this condition may be associated with autoantibodies against glutamic acid decarboxylase (GAD), an enzyme that converts the excitatory neurotransmitter glutamate to the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). Anti-GAD autoantibodies could result in excess excitatory neurotransmitters, leading to the seizures and other symptoms observed in patients with Batten disease. The pathogenic potential of GAD autoantibodies is examined in light of what is known for other autoimmune disorders, such as multiple sclerosis, SPS, Rasmussen encephalitis, and type 1 diabetes, and may have radical implications for diagnosis and management of Batten disease.

    This paper is built on our book "Aesthetics and Learning", Hans Reizels Publishers, Copenhagen 2010. In this book we describe the relationship between aesthetic creative activities and children’s development and learning, based on among other the theories of Malcolm Ross (1988), Hansjörg Hohr (2000......) and Bjørn Rasmussen (1998). According to these theories aesthetic activities are an integrated and irreplaceable part of all children's socialization. Essential activities that develops creativity and enables the child to use the aesthetic languages to reflect and communicate feelings, experiences...... and impressions, and develop understanding of herself, the others and the world she is a part of. ”In order to grasp this potential, we need to deconstruct both the concepts of "Aesthetic" and "Education" to find new ways to organize what we shall label as cultural-aesthetic and playful education” (Rasmussen...

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

    Rasmussen's encephalitis is a childhood disease resulting in intractable seizures associated with hippocampal and neocortical inflammation. An autoantibody against the GluR3 subunit of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptors is implicated in the pathophysiology of Rasmussen's encephalitis. AMPA receptors mediate excitatory neurotransmission in the brain and contain combinations of four subunits (GluR1-4). Although the distributions of GluR1, GluR2, and GluR4 are known in some detail, the cellular distribution of GluR3 in the mammalian brain remains to be described. We developed and characterized a GluR3-specific monoclonal antibody and quantified the cellular distribution of GluR3 in CA1 of the rat hippocampus. GluR3 immunoreactivity was detected in all pyramidal neurons and astrocytes and in most interneurons. We quantified the intensity of GluR3 immunoreactivity in interneuron subtypes defined by their calcium-binding protein content. GluR3 immunofluorescence, but not GluR1 or GluR2 immunofluorescence, was significantly elevated in somata of parvalbumin-containing interneurons compared to pyramidal somata. Strikingly, increased GluR3 immunofluorescence was not observed in calbindin- and calretinin-containing interneurons. Furthermore, 24% of parvalbumin-containing interneurons could be distinguished from surrounding neurons based on their intense GluR3 immunoreactivity. This subpopulation had significantly elevated GluR3 immunoreactivity compared to the rest of parvalbumin-containing interneurons. Electron microscopy revealed enriched GluR3 immunoreactivity in parvalbumin-containing perikarya at cytoplasmic and postsynaptic sites. Parvalbumin-containing interneurons, potent inhibitors of cortical pyramidal neurons, are vulnerable in the brains of epileptic patients. Our findings suggest that the somata of these interneurons are enriched in GluR3, which may render them vulnerable to pathological states such as epilepsy and

  17. Review of alpha-decay data from doubly-even nuclei

    1996-09-01

    Alpha-decay data from doubly-even nuclei throughout the periodic table are reviewed and evaluated. From these data, nuclear radius parameters are calculated by using the Preston formula for {alpha}- decay probabilities. The radius parameters for each element behave rather regularly as a function of neutron number. The show minima at the major closed shells, increase sharply for parents just above the closed shells, and decrease smoothly toward the next shell closure. The same trend is observed for {alpha} reduced widths calculated using the Rasmussen formalism. Any irregularity or large departure from this behavior indicates probable incorrect input data. This systematic behavior can also be utilized to estimate partial half- lives.

    The December 2014 issue of the European Journal of Oncology Nursing published an article by Näppä, Rasmussen, Axelsson, and Lindqvist that reported on a qualitative study of the challenges experienced by Swedish nurses when administering palliative cancer treatment at the end of life. The study identified the various clinical scenarios that create dilemmas among nurses. The authors described why chemotherapy at the end of life has become so prevalent and offered strategies to minimize or prevent the moral distress that can occur. Research from the United States identified similar trends in end-of-life treatment and supportive recommendations for multidisciplinary palliative care team collaboration as a solution.

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

    2017-03-01

    This article describes challenges encountered in applying Jens Rasmussen's Cognitive Work Analysis (CWA) framework to the practice of energy efficiency Monitoring & Targeting (M&T). Eight theoretic issues encountered in the analysis are described with respect to Rasmussen's work and the modeling solutions we adopted. We grappled with how to usefully apply Work Domain Analysis (WDA) to analyze categories of domains with secondary purposes and no ideal grain of decomposition. This difficulty encouraged us to pursue Control Task (ConTA) and Strategies (StrA) analysis, which are under-explored as bases for interface design. In ConTA we found M&T was best represented by two interlinked work functions; one controlling energy, the other maintaining knowledge representations. From StrA, we identified a popular representation-dependent strategy and inferred information required to diagnose faults in system performance and knowledge representation. This article presents and discusses excerpts from our analysis, and outlines their application to diagnosis support tools.

    Safety leadership is an important factor in supporting safety in high-risk industries. This article contends that applying systems-thinking methods to examine safety leadership can support improved learning from incidents. A case study analysis was undertaken of a large-scale mining landslide incident in which no injuries or fatalities were incurred. A multi-method approach was adopted, in which the Critical Decision Method, Rasmussen's Risk Management Framework, and Accimap method were applied to examine the safety leadership decisions and actions which enabled the safe outcome. The approach enabled Rasmussen's predictions regarding safety and performance to be examined in the safety leadership context, with findings demonstrating the distribution of safety leadership across leader and system levels, and the presence of vertical integration as key to supporting the successful safety outcome. In doing so, the findings also demonstrate the usefulness of applying systems-thinking methods to examine and learn from incidents in terms of what 'went right'. The implications, including future research directions, are discussed. Practitioner Summary This paper presents a case study analysis, in which systems-thinking methods are applied to the examination of safety leadership decisions and actions during a large-scale mining landslide incident. The findings establish safety leadership as a systems phenomenon, and furthermore, demonstrate the usefulness of applying systems-thinking methods to learn from incidents in terms of what 'went right'. Implications, including future research directions, are discussed.

    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.

    The main objective of this project is modeling of human operator in a main control room of Nuclear Power Plant. For this purpose, we carried out research on knowledge representation and inference method based on Rasmussen`s decision ladder structure. And we have developed SACOM(Simulation= Analyzer with a Cognitive Operator Model) using G2 shell on Sun workstations. SACOM consists of Operator Model, Interaction Analyzer, Situation Generator. Cognitive model aims to build a more detailed model of human operators in an effective way. SACOM is designed to model knowledge-based behavior of human operators more easily. The followings are main research topics carried out this year. First, in order to model knowledge-based behavior of human operators, more detailed scenarios are constructed. And, knowledge representation and inference methods are developed to support the scenarios. Second, meta knowledge structures are studied to support human operators 4 types of diagnoses. This work includes a study on meta and scheduler knowledge structures for generate-and-test, topographic, decision tree and case-based approaches. Third, domain knowledge structure are improved to support meta knowledge. Especially, domain knowledge structures are developed to model topographic diagnosis model. Fourth, more applicable interaction analyzer and situation generator are designed and implemented. The new version is implemented in G2 on Sun workstations. 35 refs., 49 figs. (author)

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

    Rasmussen’s encephalitis ( RE ) , which was first described by Rasmussen in 1958 , is a rare, dispersed, and progressive neurological syndrome that is characterized by focal epilepsy, unilateral inflam-mation of the cerebral cortex, progressive hemiplegia and cognitive deterioration. The etiology of this syn-drome remains under investigation, and it is hypothe-sized and widely accepted that RE is a T-cell-mediated autoimmune response. However, the antigenic epitopes and mechanisms are still unknown. The patho-logical characteristics of RE are cortical inflammation, neuronal loss, and gliosis that are confined to one cere-bral hemisphere. Hemispherectomy remains the only cure for the seizures and cognitive deterioration associ-ated with the disease, but this procedure results in inev-itable functional loss in the brain. Compared with sur-gery, immunomodulatory treatments are expected to cause less neurological deficits, but with limited clinical effect.

    Ozsvath, Rasmussen and Szabo constructed odd Khovanov homology. It is a link invariant which has the same reduction modulo 2 as (even) Khovanov homology. Szabo introduced a spectral sequence with mod 2 coefficients from mod 2 Khovanov homology to another link homology. He got his spectral sequence from a chain complex with a filtration. We give an integral lift of Szabo's complex, that provides a spectral sequence from odd Khovanov homology to a link homology, from which one can get Szabo's link homology with the Universal Coefficient Theorem. Szabo has constructed such a lift independently, but has not yet published it. This is my master thesis which I wrote under supervision of Thomas Schick at Georg August University G\\"ottingen in summer 2011. It is in German. I will publish a reworked version in English later.

  20. 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.

    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.

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

    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.

  8. [Echocardiographic evaluation of cardiac output in patients with acute myocardial infarction (author's transl)].

    Nador, F; De Martini, M; Binda, A; Salmaso, G C; Radrizzani, D; Lotto, A

    1980-01-01

    Echocardiography is a non invasive technique particularly useful to assess both hemodynamics and left ventricular performances; different methods have been proposed to evaluate echocardiographically the cardiac output. The aim of this work is to suggest a new method (planimetry of the area enclosed by echoes from the mitral valve) stating its advantages and limits and to test three already known methods (cubes method, method of Lalani and Lee, method of Rasmussen and coll.) comparing them to thermodilution. In 24 patients admitted in our Coronary Care Unit for acute myocardial infarction 30 measurements have been performed simultaneously with echocardiography and thermodilution. Statistical analysis (correlation coefficient with the method of the square minimums and Student's 't') of the results has shown that the cubes method is unprecise (P = NS) and unbiased (d = 0.97 +/- 15.46); Lalani-Lee method is unprecise (P = NS) and biased (d = 9.64 +/- 21.36) by a systematic underestimate error concealed by the poor precision; Rasmussen and coll. method is precise (P < 0.01) but biased (d = --3.03 +/- 5.5), the systematic mistake being entirely due to the group of patients with abnormal hemodynamics. Our method is precise (P < 0.01) and unbiased (d = --0.04 +/- 9.62) in patients both with normal and abnormal hemodynamics. Therefore this method offers the following advantages: 1) it is unbiased, even in the presence of abnormal left ventricular performance; 2) it is sufficiently precise, having a correlation coefficient with thermodilution of r = 0.80; 3) it measures directly the amount of flow due to the atrial systole; 4) the measurement is rapid and hardly biased by the reader.

  9. 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.

  10. 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.

In particular, in a hypothesis by Rasmussen and Arnason based on mitochondrial trees, cartilaginous fishes have a terminal position in a paraphyletic cluster of bony fishes. No previous analysis based on nuclear DNA-coded genes could significantly reject the mitochondrial trees of jawed vertebrates. Results We have cloned and sequenced seven nuclear DNA-coded genes from 13 vertebrate species. These sequences, together with sequences available from databases including 13 jawed vertebrates from eight major groups (cartilaginous fishes, bichir, chondrosteans, gar, bowfin, teleost fishes, lungfishes and tetrapods and an outgroup (a cyclostome and a lancelet, have been subjected to phylogenetic analyses based on the maximum likelihood method. Conclusion Cartilaginous fishes have been inferred to be basal to other jawed vertebrates, which is consistent with the generally accepted view. The minimum log-likelihood difference between the maximum likelihood tree and trees not supporting the basal position of cartilaginous fishes is 18.3 ± 13.1. The hypothesis by Rasmussen and Arnason has been significantly rejected with the minimum log-likelihood difference of 123 ± 23.3. Our tree has also shown that living holosteans, comprising bowfin and gar, form a monophyletic group which is the sister group to teleost fishes. This is consistent with a formerly prevalent view of vertebrate classification, although inconsistent with both of the current morphology-based and mitochondrial sequence-based trees. Furthermore, the bichir has been shown to be the basal ray-finned fish. Tetrapods and lungfish have formed a monophyletic cluster in the tree inferred from the concatenated alignment, being consistent with the currently prevalent view. It also remains possible that

    The Kaali impact field consists of nine identified craters located on the Saaremaa Island in Estonia. The largest crater is 110 m in diameter (centered around 58°22'21.94"N, 22°40'09.91" E). It was formed by impact of an IAB iron meteoroid into Silurian dolomite target rocks covered by up to a few meters of glacial till (Veski et al. 2007). The age of the Kaali impact structure is still a matter of debate, and the estimates provided by different authors vary considerably between ~6400 BC (Raukas et al. 1995, Moora et al. 2012) and ~400 BC (Rasmussen et al. 2000, Veski et al. 2001). These ages were derived by 14C dating of marker horizons, characterized by a slightly elevated iridium content within the nearby Piila bog yielding a calibrated age of 800-400 BC (Rasmussen et al. 2000, Veski et al. 2001) and occurrences of glassy siliceous material in the Piila bog (~6400 BC: Raukas et al. 1995) or iron microspherules in an organic-rich layer of the Reo gravel pit (6400 BC: Moora et al. 2012). However, the source of the foreign material within those layers was never unequivocally connected with the Kaali crater. 14C dating of material from post-impact organic sediments within Kaali impact craters yielded ages between 1800-1500 BC (Saarse et al. 1991, Veski et al. 2004) and 1450-400 BC (Aaloe et al. 1963). These dates underestimate the age of impact as organic sediments within the crater started to form at unknown period after the impact. On the other hand, Veski et al. (2004) suggested a reservoir effect that might have caused artificially "aging" of the organic matter because the crater was emplaced within Silurian dolomite which is rich in old carbon. The aim of this study is to determine the age of the Kaali crater by 14C dating of organic material covered by the continuous layer of proximal ejecta. This research was conducted in conjunction with a new structural investigation of Kaali Main (Zanetti et al. 2015). Ten samples collected from different locations

    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.

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

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

  17. Molecular fossils and the late rise of oxygenic photosynthesis

    Biomarkers are the molecular fossils of natural products such as lipids and pigments. They can yield a wealth of information about early microbial ecosystems and are particularly valuable when preserved in > 1 billion-year old (Ga) sedimentary rocks where conventional fossils are often lacking. Therefore, in 1999, the detection of traces of biomarkers in 2.5 to 2.7 Ga shales from Western Australia (Brocks et al. 1999, Summons et al. 1999) was celebrated as a breakthrough. The discovery, which was later confirmed by several independent studies, led to far reaching conclusions about the early evolution of oxygenic photosynthesis (Summons et al. 1999) and ancestral eukaryotes (Brocks et al. 1999). However, here we present new data based on the carbon isotopic composition of solidified hydrocarbons (Rasmussen et al. 2008) and the spatial distribution of liquid hydrocarbons within the original 2.5 and 2.7 Ga shales (Brocks 2011) that demonstrate that the molecules must have entered the rocks much later in Earth's history and therefore provide no information about the Archean (>2.5 Ga) biosphere or environment. The elimination of the Archean biomarker data has immense implications for our understanding of Earth's early biosphere. 2-Methylhopanes have been interpreted as evidence for the existence of cyanobacteria at 2.7 Ga, about ~300 million years before the atmosphere became mildly oxygenated in the Great Oxidation Event (GOE; between 2.45 and 2.32 Ga). Now, the oldest direct fossil evidence for cyanobacteria reverts back to 2.15 Ga, and the most ancient robust sign for oxygenic photosynthesis becomes the GOE itself. Moreover, the presence of steranes has been interpreted as evidence for the existence of ancestral eukaryotes at 2.7 Ga. However, without the steranes, the oldest fossil evidence for the domain falls into the range ~1.78-1.68 Ga. Recognition that the biomarkers from Archean rocks are not of Archean age renders permissive hypotheses about a late evolution

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

  19. "Viral déjà vu" elicits organ-specific immune disease independent of reactivity to self.

    Autoimmune diseases are often precipitated by viral infections. Yet our current understanding fails to explain how viruses trigger organ-specific autoimmunity despite thymic tolerance extending to many non-lymphohematopoietic self antigens. Additionally, a key epidemiological finding needs to be explained: In genetically susceptible individuals, early childhood infections seem to predispose them to multiple sclerosis (MS) or type 1 diabetes years or even decades before clinical onset. In the present work, we show that the innate immune system of neonatal mice was sufficient to eliminate an attenuated lymphocytic choriomeningitis virus (LCMV) from most tissues except for the CNS, where the virus persisted in neurons (predisposing virus). Virus-specific cytotoxic T cells (CTLs) were neither deleted nor sufficiently primed to cause disease, but they were efficiently triggered in adulthood upon WT LCMV infection (precipitating virus). This defined sequence of viral infections caused severe CNS inflammation that was histomorphologically reminiscent of rasmussen encephalitis, a fatal human autoimmune disease. Yet disease in mice was mediated by antiviral CTLs targeting an epitope shared by the precipitating virus and the predisposing virus persisting in neurons (déjà vu). Thus the concept of "viral déjà vu" demonstrates how 2 related but independently encountered viral infections can cause organ-specific immune disease without molecular mimicry of self and without breaking self tolerance.

    My first encounter with human factors happened in early 1973: I was performing a reliability assessment of the safety injection system of the Fessenheim reactor, and I found that the operators had to switch to the recirculation phase manually and had only 6 min between the low and low-low level alarm indicating that the water tank was empty. It of course led us to replace this manual action by an automatic positioning for the recirculation phase. In July of the same year, I attended a North Atlantic Treaty Organization workshop in Liverpool on reliability assessment, and I met Alan Swain from the United States and Jens Rasmussen from Denmark. During the long rainy evenings of the seminar, we had time to discuss human errors and human factors, and that was the beginning of a very fruitful collaboration between us. I realized then the complexity of the problem. Quantification needs were obvious for reliability and risk assessment studies, but, at the same time, there were needs for better understanding of human behavior and the mechanisms that could lead to human errors. Knowledge of the man-machine interface also seemed very poor, although some basic ergonomic rules were available and could be applied. But a major problem was the lack of data.

    Rasmussen's encephalitis (RE), a childhood disease characterized by epileptic seizures associated with progressive destruction of a single cerebral hemisphere, is an autoimmune disease in which one of the autoantigens is a glutamate receptor, GluR3. The improvement of some affected children following plasma exchange that removed circulating GluR3 antibodies (anti-GluR3) suggested that anti-GluR3 gained access to the central nervous system where it exerted deleterious effects. Here, we demonstrate that a subset of rabbits immunized with a GluR3 fusion protein develops a neurological disorder mimicking RE. Anti-GluR3 IgG isolated from serum of both ill and healthy GluR3-immunized animals promoted death of cultured cortical cells by a complement-dependent mechanism. IgG immunoreactivity decorated neurons and their processes in neocortex and hippocampus in ill but not in healthy rabbits. Moreover, both IgG and complement membrane attack complex (MAC) immunoreactivity was evident on neurons and their processes in the cortex of a subset of patients with RE. We suggest that access of IgG to epitopes in the central nervous system triggers complement-mediated neuronal damage and contributes to the pathogenesis of both this animal model and RE.

    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.

    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.

    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...

    2013-11-01

    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.

    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).

    The only stable NMR-active isotope of strontium, (87)Sr, is a spin-9/2 quadrupolar nucleus that has a low gyromagnetic ratio, a low natural abundance, and a large nuclear electric quadrupole moment. In this work, we utilize the quadrupolar Carr-Purcell-Meiboom-Gill (QCPMG) pulse sequence and a 21.14 T NMR spectrometer at the Pacific Northwest National Laboratory to characterize the strontium sites in the natural minerals strontianite (SrCO(3)) and celestine (SrSO(4)). QCPMG at 21.14 T was found to provide sensitivity enhancements of roughly two orders of magnitude over Hahn-echo experiments at an 11.74 T magnetic field. We extracted the quadrupolar parameters for the strontium nuclei through iterative simulations of the experimental spectra with the SIMPSON program by Bak, Rasmussen, and Nielsen. The data show that the quadrupolar parameters of (87)Sr appear to be highly sensitive to the symmetry of the strontium coordination environment and can thus provide information about the strontium binding environment in complex systems.

    A large protein was purified from bovine kidney, using selective extraction with EDTA to solubilize proteins anchored by divalent cation-dependent interactions. An antiserum raised against the purified protein labeled the apical cell surface of the epithelial cells in proximal tubules and the luminal surface of small intestine. Ten peptide sequences, derived from the protein, all matched the recently published sequences for rat (Moestrup, S. K., Kozyraki, R., Kristiansen, M., Kaysen, J. H., Holm Rasmussen, H., Brault, D., Pontillon, F., Goda, F. O., Christensen, E. I., Hammond, T. G., and Verroust, P. J. (1998) J. Biol. Chem. 273, 5235-5242) and human cubilin, a receptor for intrinsic factor-vitamin B12 complexes, identifying the protein as bovine cubilin. In electron microscopy, a three-armed structure was seen, indicating an oligomerization of three identical subunits. This model was supported by the Mr values of about 1,500,000 for the intact protein and 440,000 for its subunits obtained by analytical ultracentrifugation. In a search for a potential assembly domain, we identified a region of heptad repeats in the N-terminal part of the cubilin sequence. Computer-assisted analysis supported the presence of a coiled-coil alpha-helix between amino acids 103 and 132 of the human cubilin sequence and predicted the formation of a triple coiled-coil. We therefore conclude that cubilin forms a noncovalent trimer of identical subunits connected by an N-terminal coiled-coil alpha-helix.

    The reciprocity calibration method uses two microphones acoustically connected by a coupler, a cylindrical cavity closed at each end by the diaphragms of the transmitting and receiving microphones. The acoustic transfer admittance of the coupler, including the thermal conductivity effect of the fluid, must be modelled precisely to obtain the accurate sensitivity of the microphones from the electrical transfer impedance measurement. It appears that the analytical model quoted in the current standard [International Electrotechnical Commission IEC 61064-2, Measurement Microphones, Part 2: Primary Method for Pressure Calibration of Laboratory Standard Microphones by the Reciprocity Technique, 1992] is not the appropriate one and that it should be revised, as also suggested by a recent EUROMET project report [K. Rasmussen, Datafiles simulating a pressure reciprocity calibration of microphones, EUROMET Project 294 Report PL-13, 2001]. Thus, it is the aim of the paper to investigate analytically the acoustic field inside the coupler, revisiting the assumptions of the earlier work, leading to a coherent description and therefore providing clarity which should facilitate discussion of a possible revised standard.

    Multimodal Pain Management after Arthroscopic Surgery By Sten Rasmussen, M.D. The thesis is based on four randomized controlled trials. The main hypothesis was that multimodal pain treatment provides faster recovery after arthroscopic surgery. NSAID was tested against placebo after knee arthrosco...... after knee and ankle arthroscopy with the use of oral NSAIDs combined with bupivacaine plus morphine or combined with bupivacaine, morphine plus steroid....... ankle arthroscopy. Oral NSAID reduced time to work from 17 to 14 days after knee arthroscopy. Intra-articular treatment with bupivacaine plus morphine and bupivacaine plus morphine plus steroid after arthroscopic knee meniscectomy reduced time to work from 10 to 5 to 3 days. Intraarticular treatment...... with bupivacaine plus morphine and bupivacaine plus morphine plus steroid after diagnostic knee arthroscopy reduced time to work from 10 to 5 to 2 days. Additional analysis revealed that the surgical trauma and the use of tourniquet influenced recovery. The thesis proves a reduction in the time to return to work...

  15. 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.

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.

    Plants have evolved on the earth, indicating the morphology, growth and development, and life cycle of plants are highly influenced by gravity as well as other environmental stimuli. Indeed, simulated microgravity on a clinostat or hypergravity on a centrifuge has recently been reported to change the growth and development of plants (Hoson et al. 1992, 1993, 1995, Rasmussen et al. 1994, Kasahara et al. 1995). Senescence is a final drastic phenomenon in life cycle of plants, which is characterized by the loss of total chlorophyll and protein, and/or the formation of the abscission (Osborne 1973, Thimann 1977, Addicott 1982). Many environmental stimuli as well as the qualitative and quantitative changes of plant hormones have been reported to affect plant senescence. Among those stimuli, light is the most important factor to regulate plant senescence (Leopold 1964). Dark condition promotes leaf senescence due to the decrease in endogenous level of cytokinin and/or the increase in that of abscisic acid or ethylene (Tetley and Thimann 1974, Gepstein and Thimann 1980). However, there are few reports concerning the effect of gravity on leaf senescence. Strenuous effort to learn leaf senescence under microgravity condition has been done using a three-dimensional (3-D) clinostat. In this paper, we report that simulated microgravity condition on a 3-D clinostat promoted the senescence of oat leaf segments in the dark. A possible mechanism of microgravity condition on promoting the senescence is also discussed.

    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.

    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.

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

    Science.gov (United States)

    Schudy, Robert

    1987-01-01

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

  3. Street Cries and the urban ritornelle

    Jacob Kreutzfeldt

    2012-04-01

    Full Text Available Street cries, though rarely heard in Northern European cities today, testify to ways in which audible practices shape and structure urban spaces. Paradigmatic for what Gilles Deleuze and Felix Guattari call ‘the refrain’, the ritualised and stylised practice of street cries may point at the dynamics of space-making, through which the social and territorial construction of urban space is performed. The article draws on historical material, documenting and describing street cries, particularly in Copenhagen in the years 1929 to 1935. Most notably, the composer Vang Holmboe and the architect Steen Eiler Rasmussen have investigated Danish street cries as a musical and a spatial phenomenon, respectably. Such studies – from their individual perspectives – can be said to explore the aesthetics of urban environments, since street calls are developed and heard specifically in the context of the city. Investigating the different methods employed in the two studies and presenting Deleuze and Guattari’s theory of the refrain as a framework for further studies in the field, this article seeks to outline a fertile area of study for sound studies: the investigation of everyday refrains and the environmental relations they express and perform. Today changed sensibilities and technologies have rendered street crying obsolete in Northern Europe, but new urban ritornells may have taken their place.

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

    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.

    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

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

    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.

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

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

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

    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

    This study applies the AcciMap methodology, which was originally proposed by Professor Jens Rasmussen (1997), to the analysis of the tragic Sewol Ferry accident in South Korea on April 16, 2014, which killed 304 mostly young people and is considered as a national disaster in that country. This graphical representation, by incorporating associated socio-technical factors into an integrated framework, provides a big-picture to illustrate the context in which an accident occurred as well as the interactions between different levels of the studied system that resulted in that event. In general, analysis of past accidents within the stated framework can define the patterns of hazards within an industrial sector. Such analysis can lead to the definition of preconditions for safe operations, which is a main focus of proactive risk management systems. In the case of the Sewol Ferry accident, a lot of the blame has been placed on the Sewol's captain and its crewmembers. However, according to this study, which relied on analyzing all available sources published in English and Korean, the disaster is the result of a series of lapses and disregards for safety across different levels of government and regulatory bodies, Chonghaejin Company, and the Sewol's crewmembers. The primary layers of the AcciMap framework, which include the political environment and non-proactive governmental body; inadequate regulations and their lax oversight and enforcement; poor safety culture; inconsideration of human factors issues; and lack of and/or outdated standard operating and emergency procedures were not only limited to the maritime industry in South Korea, and the Sewol Ferry accident, but they could also subject any safety-sensitive industry anywhere in the world.

    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.

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

  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.

    Microbiological analysis has been made of 120 samples from biotopes of the western coast of the Antarctic peninsula (Rasmussen cope, Tuxen cope, Waugh mountain), Argentine archipelago islands (Galindez, Skua, Corner, Barchans, Irizar, Uruguay, Cluls, Three Little Pigs, King-George), as well as neighbouring islands (Petermann--on the north, a group of Jalour islands--on the east, Berthelot--on the south-east); and more remote islands (Darboux, Lippmann, Booth). It was found out that the total number of chemoorganotrophic aerobic microorganisms was 10(6) - 10(8) cells/g of soil, that was by 2-3 orders lower than in the regions with temperate climate. One can observe a tendency of decreasing the quantity of chemoorganotrophic microorganisms in the Antartic biotopes (cells/g of a sample) in the following order: soil (1 x 10(7) - 8 x 10(8)), underground part of moss (1 x 10(6) - 5 x 10(7)), grass Deschampsia antarctica (10(6) - 10(8), slit of fresh-water reservoir (10(5) - 10(7)), ground part of moss (10(3) - 10(6)), lichens (10(3) - 10(6)). Representatives of several phylogenetic lines: Proteobacteria (genera Pseudomonas, Methylobacterium, Enterobacter), Firmicutes (genera Bacillus, Staphylococcus), Actinobacteria (genera Brevibacterium, Actinomyces, Streptomyces) have been found in the Antarctic samples. As a rule, genera of bacteria found in the Antarctic Region are widely distributed in different regions of the Earth with temperate climate. Microorganisms similar to the species Exophiala nigra (Issatsch.) Haats et de Hoog 1999, which was first detected 100 years ago by Academician B.L. Isachenko in the Arctic region water, were also isolated from biofilms on vertical rocks of the Galindez Island as well as from the soil of the Irizar Island.

    Advocates of systems thinking approaches argue that accident prevention strategies should focus on reforming the system rather than on fixing the "broken components." However, little guidance exists on how organizations can translate incident data into prevention strategies that address the systemic causes of accidents. This article describes and evaluates a series of systems thinking prevention strategies that were designed in response to the analysis of multiple incidents. The study was undertaken in the led outdoor activity (LOA) sector in Australia, which delivers supervised or instructed outdoor activities such as canyoning, sea kayaking, rock climbing and camping. The design process involved workshops with practitioners, and focussed on incident data analyzed using Rasmussen's AcciMap technique. A series of reflection points based on the systemic causes of accidents was used to guide the design process, and the AcciMap technique was used to represent the prevention strategies and the relationships between them, leading to the creation of PreventiMaps. An evaluation of the PreventiMaps revealed that all of them incorporated the core principles of the systems thinking approach and many proposed prevention strategies for improving vertical integration across the LOA system. However, the majority failed to address the migration of work practices and the erosion of risk controls. Overall, the findings suggest that the design process was partially successful in helping practitioners to translate incident data into prevention strategies that addressed the systemic causes of accidents; refinement of the design process is required to focus practitioners more on designing monitoring and feedback mechanisms to support decisions at the higher levels of the system.

Houve melhora dos aspectos sociais, ambientais, efeitos de medicação, percepção de controle de crises e do nível geral de qualidade de vida do grupo, havendo correlação positiva entre o controle de crises epilépticas e a percepção dos pais quanto à melhora da qualidade de vida. CONCLUSÃO: A melhora da qualidade de vida detectada na avaliação pós-cirúrgica correlacionou-se com o controle de crises; diferentemente, as repercussões neuropsicológicas dependeram de vários fatores como tipo de epilepsia, etiologia e tipo de cirurgia.

  2. 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.

    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

    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.

    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 .

    The United States is highly dependent on space resources to support military, government, commercial, and research activities. Satellites operate at great distances, observation capacity is limited, and operator actions and observations can be significantly delayed. Safe operations require support systems that provide situational understanding, enhance decision making, and facilitate collaboration between human operators and system automation both in-the-loop, and on-the-loop. Joint cognitive systems engineering (JCSE) provides a rich set of methods for analyzing and informing the design of complex systems that include both human decision-makers and autonomous elements as coordinating teammates. While, JCSE-based systems can enhance a system analysts' understanding of both existing and new system processes, JCSE activities typically occur outside of traditional systems engineering (SE) methods, providing sparse guidance about how systems should be implemented. In contrast, the Joint Director's Laboratory (JDL) information fusion model and extensions, such as the Dual Node Network (DNN) technical architecture, provide the means to divide and conquer such engineering and implementation complexity, but are loosely coupled to specialized organizational contexts and needs. We previously describe how Dual Node Decision Wheels (DNDW) extend the DNN to integrate JCSE analysis and design with the practicalities of system engineering and implementation using the DNN. Insights from Rasmussen's JCSE Decision Ladders align system implementation with organizational structures and processes. In the current work, we present a novel approach to assessing system performance based on patterns occurring in operational decisions that are documented by JCSE processes as traces in a decision ladder. In this way, system assessment is closely tied not just to system design, but the design of the joint cognitive system that includes human operators, decision-makers, information systems, and

  7. 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.

    Human visual cortex contains maps of the visual field. Much research has been dedicated to answering whether and when these visual field maps change if critical components of the visual circuitry are damaged. Here, we first provide a focused mini-review of the functional magnetic resonance imaging (fMRI) studies that have evaluated the human cortical visual field maps in the face of retinal lesions, brain injury, and atypical retinocortical projections. We find that there is a fair body of research that has found abnormal fMRI activity, but also that this abnormal activity does not necessarily stem from cortical remapping. The abnormal fMRI activity can often be explained in terms of task effects and/or the uncovering of normally hidden system dynamics. We then present the case of a 16-year-old patient who lost the entire left cerebral hemisphere at age three for treatment of chronic focal encephalitis (Rasmussen syndrome) and intractable epilepsy. Using an fMRI retinotopic mapping procedure and population receptive field (pRF) modeling, we found that (1) despite the long period since the hemispherectomy, the retinotopic organization of early visual cortex remained unaffected by the removal of an entire cerebral hemisphere, and (2) the intact lateral occipital cortex contained an exceptionally large representation of the center of the visual field. The same method also indicates that the neuronal receptive fields in these lateral occipital brain regions are extraordinarily small. These features are clearly abnormal, but again they do not necessarily stem from cortical remapping. For example, the abnormal features can also be explained by the notion that the hemispherectomy took place during a critical period in the development of the lateral occipital cortex and therefore arrested its normal development. Thus, caution should be exercised when interpreting abnormal fMRI activity as a marker of cortical remapping; there are often other explanations.

    Twenty-three patients with various intractable seizure patterns were divided into four groups based on their most frequent seizure type and their clinical and EEG response to chronic electrical stimulation of the centromedian thalamic nuclei (ESCM): group A, generalized tonic-clonic (GTC, n = 9); group B, partial motor (Rasmussen type) (n = 3); group C, complex partial seizures (CPS, n = 5); and group D, generalized tonic seizures (Lennox-Gastaut type) (n = 6). CM were radiologically and electrophysiologically localized by means of stereotaxic landmarks and by thalamically induced scalp recruiting-like responses and desynchronization. ESCM consisted of daily 2-h stimulation sessions for 3 months. Each stimulus consisted of a 1-min train of square pulses with a 4-min interstimulus interval, alternating right and left CM. Each pulse was 1.0 ms in duration at 60/s frequency and 8-15 V (400-1,250 microA) amplitude. Voltage (V), current flow (microA) and impedance (k omega) at the electrode tips were kept constant. A significant decrease in the number of seizures per month and paroxysmal EEG waves per 10-s spochs occurred in group A patients between the baseline period (BL) and the ESCM period. These changes persisted for > 3 months after discontinuation of ESCM (poststimulation period, Post). Post was accompanied by a significant decrease in the number of paroxysmal EEG discharges. A substantial decrease in seizures and paroxysmal discharges was also observed in patients of group B. In contrast, patients of groups C and D showed no significant changes from BL to ESCM and Post periods, except for a significant decrease in the number of seizures in group D patients from BL to Post periods.

    A prototype 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 a 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 taken into account. The plant model of a 3-loop PWR is also developed using a best estimate thermal-hydraulic analysis code RELAP5/MOD2. This report is prepared as User's Manual for JACOS. The first chapter of this report describes both operator and plant models in detail. The second chapter includes instructive descriptions for program installation, building of a knowledge base for operator model, execution of simulation and analysis of simulation results. The examples of simulation with JACOS are shown in the third chapter. (author)

    The purpose of our study was to compare the outcome after minimally invasive reconstruction and internal fixation with and without the use of pre- and intra-operative real size 3D printing for patients with displaced tibial plateau fractures (TPFs). We prospectively followed up 40 consecutive adult patients with closed TPF who underwent surgical treatment of reconstruction of the tibial plateau with the use of minimally invasive fixation. Sixteen patients (group 1) were operated using a pre-operative and intra-operative real size 3D-model, while 24 patients (group 2) were operated without 3D-model printing, but using only pre-operative and intra-operative 3D Tc-scan images. The mean operating time was 148.2±15.9min for group 1 and 174.5±22.2min for group 2 (p=0.041). In addition, the mean intraoperative blood loss was less in group 1 (520mL) than in group 2 (546mL) (p=0.534). After discharge, all patients were followed up at 6 weeks, 12 weeks, 6 months, 1year and then every year post surgically and radiographic evaluation was carried out each time using clinical and radiological Rasmussen's score, with no significant differences between the two groups. Two patients (group 2) developed infection which resolved within 3 weeks after usage of antibiotics. Neither superficial nor deep infections were present in group 1. In all patients, no non-union occurred. No intraoperative, perioperative, or postoperative complications, such as loss of valgus correction, bone fractures, or metallic plate failures were detected at follow-up. In patients operated with the use of 3D-model printing, we found a significant reduction in surgical time. Moreover, the technique without a 3D-model increased the patient's and the surgeon's exposure to radiation.

      BACKGROUND: Studies have shown the knee secondary osteoarthritis may occur after the treatment of tibial plateau fractures with open reduction and internal fixation, but the researches on the middle- and long-term effect of arthroscopic assisted tibial plateau fracture fixation are stil rare. OBJECTIVE: To evaluate the outcomes of lateral tibial plateau fractures after treated with arthroscopic assisted percutaneous bone grafting and screw fixation for 1 and 4 years through clinical and radiological assessment. METHODS: Between March 2007 and March 2009, with the information of the patients with lateral tibial plateau fractures undergoing arthroscopic assisted percutaneous bone grafting and screw fixation were enrol ed. The data of the type of fractures in the Schatzker classification, the accompanying lesions of the cartilage defect on the lateral tibial plateau, the cartilage damage on the femoral condyle, intra-articular soft tissue lesions and insufficient reduction of the fracture, as wel as postoperative subsidence in the lateral tibial plateau were col ected. The Lysholm score, Ahlback osteoarthritis classification, Rasmussen function score and radiological score were assessed at 1 and 4 years after treated with percutaneous bone grafting and screw fixation. RESULTS AND CONCLUSION: Twenty-three patients finished the fol ow-up. At 1 and 4 years after percutaneous bone grafting and screw fixation, the mean Lysholm score was 90 and 87 points respectively (P=0.23), and the mean Rasmussen function score was 26 and 24 points respectively (P=0.30). At 4 years after surgery, 11 cases (47.8%) presented osteoarthritis and the Rasmussen radiological score was decreased from early postoperative 17.4 points to 4-year postoperatively 13.6 points (P=0.01). No correlation could be observed between the various types of fractures and their prognosis.

The two major training modalities in COPD rehabilitation, endurance training (ET and resistance training (RT, may both be efficient in improving muscle strength, exercise capacity, and health-related quality of life, but the effects on quadriceps muscle characteristics have not been thoroughly described.Methods: Thirty COPD patients (forced expiratory volume in 1 second: 56% of predicted, standard deviation [SD] 14 were randomized to 8 weeks of ET or RT. Vastus lateralis muscle biopsies were obtained before and after the training intervention to assess muscle morphology and metabolic and angiogenic factors. Symptom burden, exercise capacity (6-minute walking and cycle ergometer tests, and vascular function were also assessed.Results: Both training modalities improved symptom burden and exercise capacity with no difference between the two groups. The mean (SD proportion of glycolytic type IIa muscle fibers was reduced after ET (from 48% [SD 11] to 42% [SD 10], P<0.05, whereas there was no significant change in muscle fiber distribution with RT.

    Polar Lows (hereafter PL) are intensive mesoscale cyclones, appearing above the sea surface, usually behind the arctic front and characterized by severe weather conditions [1]. All in consequence of the global warming PLs started to emerge in the arctic water area as well - in summer and autumn. The research goal is to examine PLs by considering multisensory data and the resulting numerical mesoscale model. The main purpose was to realize which conditions induce PL development in such thermodynamically unusual season and region as Kara sea. In order to conduct the analysis we used visible and infrared images from MODIS (Aqua). Atmospheric water vapor V, cloud liquid water Q content and surface wind fields W were resampled by examining AMSR-E microwave radiometer data (Aqua)[2], the last one was additionally extracted from QuickSCAT scatterometer. We have selected some PL cases in Kara sea, appeared in autumn of 2007-2008. Life span of the PL was between 24 to 36 hours. Vortexes' characteristics were: W from 15m/s, Q and V values: 0.08-0.11 kg/m2 and 8-15 kg/m2 relatively. Numerical experiments were carried out with Weather Research and Forecasting model (WRF), which was installed on supercomputer "Lomonosov" of Research Computing Center of Moscow State University [3]. As initial conditions was used reanalysis data ERA-Interim from European Centre for Medium-Range Weather Forecasts. Numerical experiments were made with 5 km spatial resolution, with Goddard center microphysical parameterization and explicit convection simulation. Modeling fields were compared with satellite observations and shown good accordance. Than dynamic characteristics were analyzed: evolution of potential and absolute vorticity [4], surface heat and momentum fluxes, and CAPE and WISHE mechanisms realization. 1. Polar lows, J.

    In workplaces where activity continues around the clock, human error has been observed to exhibit a circadian rhythm, with a characteristic peak in the early hours of the morning. Errors are commonly distinguished by the nature of the underlying cognitive failure, particularly the level of intentionality involved in the erroneous action. The Skill-Rule-Knowledge (SRK) framework of Rasmussen is used widely in the study of industrial errors and accidents. The SRK framework describes three fundamental types of error, according to whether behavior is under the control of practiced sensori-motor skill routines with minimal conscious awareness; is guided by implicit or explicit rules or expertise; or where the planning of actions requires the conscious application of domain knowledge. Up to now, examinations of circadian patterns of industrial errors have not distinguished between different types of error. Consequently, it is not clear whether all types of error exhibit the same circadian rhythm. A survey was distributed to aircraft maintenance personnel in Australia. Personnel were invited to anonymously report a safety incident and were prompted to describe, in detail, the human involvement (if any) that contributed to it. A total of 402 airline maintenance personnel reported an incident, providing 369 descriptions of human error in which the time of the incident was reported and sufficient detail was available to analyze the error. Errors were categorized using a modified version of the SRK framework, in which errors are categorized as skill-based, rule-based, or knowledge-based, or as procedure violations. An independent check confirmed that the SRK framework had been applied with sufficient consistency and reliability. Skill-based errors were the most common form of error, followed by procedure violations, rule-based errors, and knowledge-based errors. The frequency of errors was adjusted for the estimated proportion of workers present at work/each hour of the day

    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.

Technical actions, heart rate, and locomotor activity in 7v7 and 8v8 games for female youth soccer players. J Strength Cond Res 30(12): 3298-3303, 2016-The purpose of this study was to evaluate technical performance, heart rate (HR), and activity profile in 7v7 and 8v8 soccer games for 9- to 10-year-old girls (U11). A total of 24 female youth players participated in the study, all playing 20-minute 7v7 and 8v8 games with 160 and 223 m per player, respectively. Technical actions, HR, and activity profile were measured during the games using video filming, HR monitors, and 5-Hz Global positioning system (GPS) units. The number of technical actions was higher in 7v7 than in 8v8 games (34 ± 19 vs. 28 ± 14; p = 0.03; d = 0.37), as was the number of successful actions (25 ± 16 vs. 20 ± 12; p = 0.01; d = 0.35), with no difference in success rate for technical actions (70 ± 13 vs. 69 ± 14%; p = 0.63; d = 0.07). No differences were found between 7v7 and 8v8 in total distance covered (1,574 ± 251 and 1,622 ± 281 m; p = 0.66; d = 0.18), peak speed (19.5 ± 2.6 and 20.7 ± 1.5 km·h; p = 0.16; d = 0.56), mean HR values (85 ± 5 and 86 ± 6%HRpeak; p = 0.85; d = 0.18), and time of >90% HRpeak (37 ± 16 and 35 ± 14% of playing time; p = 0.70; d = 0.13). Distance covered at the highest running speeds of >16 km·h was lower in 7v7 than in 8v8 games (34 ± 24 vs. 63 ± 34 m; p = 0.018; d = 0.98), as was the number of entries into this speed zone (8 ± 5 vs. 13 ± 7; p = 0.006; d = 0.82). In conclusion, more technical actions and successful actions were observed in 7v7 than in 8v8 games, but players covered more ground with high-speed running in 8v8 games. This study also revealed that HR values were high in both game formats for U11 adolescent female players, with no difference between formats.

  2. The INTIMATE event stratigraphy and recommendations for its use

    2014-05-01

    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. The work presented is a part of a manuscript under review for publication in Quaternary Science Reviews. Author team: S.O. Rasmussen, M. Bigler, S.P.E. Blockley, T. Blunier, S.L. Buchardt, H.B.

The purpose of this study was to describe the process used to translate the WOOS into Danish and to test the translation in a Danish population, in terms of validity, reliability, and responsiveness. Material and methods: The translation of the WOOS was done according to international standardized guidelines. The psychometric properties were tested in 20 consecutive patients. The eligibility criteria were: a diagnosis of osteoarthritis without symptomatic rotator cuff pathology and treated with primary shoulder replacement. Patients were excluded only in the case of other pathology of the upper extremity or in the case of cognitive or linguistic impairment compromising the ability to complete the questionnaires. Results: The Pearson's correlation coefficient between the WOOS and the Constant-Murley score (CMS, preoperatively was 0.62 (P = 0.004 and the correlation between the changes of score for the WOOS and CMS was 0.73 (P < 0.001. The correlation coefficient between the WOOS and the CMS, SF-36, and the Oxford Shoulder Score postoperatively was 0.82 (P < 0.001, 0.48 (P = 0.03, and 0.82 (P < 0.001, respectively.

The purpose of this study was to validate the Danish version of WOOS for OA and fractures (FRs using modern test theory.Patients and methods: The study included 1,987 arthroplasties in 1,943 patients that were reported to the Danish Shoulder Arthroplasty Register between 2006 and 2011. These included 847 OA and 1,140 FR cases.Results: Principal component analysis indicated the unidimensionality of WOOS. The person reliabilities showed a floor-ceiling effect, indicating that a dichotomy was the best fit for the WOOS scale. For OA, WOOS showed good reliability (item and person reliability of 0.98 and 0.76 and good targeting, with a person mean of -0.56 logits. FR also showed good targeting (person mean of -0.08 and good reliability (item and person reliabilities of 1.00 and 0.86, respectively. All WOOS items fit well with the OA sample except items 5 and 6 (pertaining to grinding and the influence of weather. In addition, item 6 showed signs of degrading the scale with an outfit mean square of 2.46. Only item 6 showed a misfit for FR with no sign of scale degradation. The residual principal component analysis confirmed the unidimensionality of FR but not OA. Six items displayed clinically significant differential item functioning between OA and FR.Conclusion: Rasch analysis showed that WOOS had a good fit with the Rasch model when used as a dichotomous scale for OA and FR. However, the results were valid only when WOOS was divided into two categories with a threshold of 950 (50% of the maximum score. For the use of WOOS in future clinical research, we recommend that a dichotomous score

    The present paper describes the development, validation and application of a method for inorganic arsenic (iAs) determination in rice samples. The separation of iAs from organoarsenic compounds was done by off-line solid-phase extraction (SPE) followed by hydride generation atomic absorption spectrometry (HG-AAS) detection. This approach was earlier developed for seafood samples (Rasmussen et al., Anal Bioanal Chem 403:2825-2834, 2012) and has in the present work been tailored for rice products and further optimised for a higher sample throughput and a lower detection limit. Water bath heating (90 °C, 60 min) of samples with dilute HNO3 and H2O2 solubilised and oxidised all iAs to arsenate (As(V)). Loading of buffered sample extracts (pH 6 ± 1) followed by selective elution of arsenate from a strong anion exchange SPE cartridge enabled the selective iAs quantification by HG-AAS, measuring total arsenic (As) in the SPE eluate. The in-house validation gave mean recoveries of 101-106% for spiked rice samples and in two reference samples. The limit of detection was 0.02 mg kg(-1), and repeatability and intra-laboratory reproducibility were less than 6 and 9%, respectively. The SPE HG-AAS method produced similar results compared to parallel high-performance liquid chromatography coupled to inductively coupled plasma mass spectrometry (ICP-MS) analysis. The SPE separation step was tested collaboratively, where the laboratories (N = 10) used either HG-AAS or ICP-MS for iAs determination in a wholemeal rice powder. The trial gave satisfactory results (HorRat value of 1.6) and did not reveal significant difference (t test, p > 0.05) between HG-AAS and ICP-MS quantification. The iAs concentration in 36 rice samples purchased on the Danish retail market varied (0.03-0.60 mg kg(-1)), with the highest concentration found in a red rice sample.

    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

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

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 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

    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

    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

Along with this, a clinical database for program monitoring and research purposes was established. Objective: The aim of this study was to estimate the agreement and validity of diagnosis and procedure codes in the Danish Colorectal Cancer Screening Database (DCCSD. Methods: All individuals with a positive immunochemical fecal occult blood test (iFOBT result who were invited to screening in the first 3 months since program initiation were identified. From these, a sample of 150 individuals was selected using stratified random sampling by age, gender and region of residence. Data from the DCCSD were compared with data from hospital records, which were used as the reference. Agreement, sensitivity, specificity and positive and negative predictive values were estimated for categories of codes “clean colon”, “colonoscopy performed”, “overall completeness of colonoscopy”, “incomplete colonoscopy”, “polypectomy”, “tumor tissue left behind”, “number of polyps”, “lost polyps”, “risk group of polyps” and “colorectal cancer and polyps/benign tumor

    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.

    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.

    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

    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

    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

    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. The work presented is under review for publication in Quaternary Science Reviews. Author team: I.K. Seierstad, P. Abbott, M. Bigler, T. Blunier, A. Bourne, E. Brook, S.L. Buchardt, C. Buizert, H.B.

    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

    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.

Compositional and geochronologic data indicate likely in situ garnet growth during a late Archean greenschist facies metamorphic event. These dates are generally consistent with published monazite ages placing a metamorphic event at ~ca.2.65Ga [4,5]. It remains possible that an as yet unidentified detrital garnet component is present and may explain some of the scatter in absolute age.

  11. 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

Unfortunately, there is a lack of research on ADHD in older adults, and until recently only a few case reports existed.Method: A systematic search was conducted in the databases Medline/PubMed and PsycINFO in order to identify studies regarding ADHD in adults ≥50 years.Results: ADHD persists into older ages in many patients, but the prevalence of patients fulfilling the criteria for the diagnosis at age ≥50 years is still unknown. It is reason to believe that the prevalence is falling gradually with age, and that the ADHD symptom level is significantly lower in the age group 70–80 years than the group 50–60 years. There is a lack of controlled studies of ADHD medication in adults ≥50 years, but this review suggests that many patients aged ≥50 years experience beneficial effects of pharmacological treatment. The problem with side effects and somatic complications may rise to a level that makes pharmacotherapy for ADHD difficult after the age of 65 years. Physical assessment prior to initiation of ADHD medication in adults ≥50 years should

  17. Peopling of the high Arctic - induced by sea ice?

    '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

    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.

This explains the gradual rise in Ir content prior to the peak event at the boundary layer (Hansen et al. 1988) and the gradual decrease in Ir content found in the sediments after the peak event.

    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.

    statives in -ėti are an unproductive derivational category in Modern Lithuanian. It is still possible to identify some isolated groups characterized by presents in -ė-ja, -i, -i-si or -a. Predominant inchoative semantics of Lithuanian denominatives in -ėti is probably to be considered an innovation. As inchoatives in -ėti, -ėja started to gain ground, at least some statives adopted i-stem presents (a typical feature of deverbative statives. If Indo-European formations in *-eh1- primarily had presents in *-eh1-i̯e/o- (as argued by Jasanoff 200212003, 147; cf. reconstructions of athematic inflection *-eh1-ti by Watkins 1971, 83; Jasanof f 1978, 124; Ruijgh 2004, 56 and zero-grade suffix in *-e-h1-ie/o- suggested by Rasmussen 1993, 481 and Hardarson 1998, 337, the more archaic morphology was taken over by the dominating inchoative type in Lithuanian, while the possibly archaic stative type lost the morphological uniformity of the present stem and drifted towards deverbative i-presents. Many of the latter ones became derivationally obscure as verbs in -ėti, -i can be considered as bases for the productive formation of deverbative u-stem adjectives in Modern Lithuanian. The space left by (formerly productive? statives in -ėti was taken over by new denominative suffixes, cf.: gudr-áuti ‘to act using tricks’ : gudrùs ‘clever, cunning’, draug-áuti ‘to be friends’ : draũgas ‘friend’, balt-úoti ‘to be white’ : báltas ‘white’, šnip-inė́ti ‘to spy’: šnìpas ‘spy’.
