The maintenance of undifferentiated human pluripotent stem cells (hPSC) under xeno-free condition requires the use of human feeder cells or extracellular matrix (ECM) coating. However, human-derived sources may cause human pathogen contamination by viral or non-viral agents to the patients. Here we demonstrate feeder-free and xeno-free culture system for hPSC expansion using diffusion assisted synthesis-grown nanocrystalline graphene (DAS-NG), a synthetic non-biological nanomaterial which completely rule out the concern of human pathogen contamination. DAS-NG exhibited advanced biocompatibilities including surface nanoroughness, oxygen containing functional groups and hydrophilicity. hPSC cultured on DAS-NG could maintain pluripotency in vitro and in vivo, and especially cell adhesion-related gene expression profile was comparable to those of cultured on feeders, while hPSC cultured without DAS-NG differentiated spontaneously with high expression of somatic cell-enriched adhesion genes. This feeder-free and xeno-free culture method using DAS-NG will facilitate the generation of clinical-grade hPSC.

On the optimal sampling of bandpass measurement signals through data acquisition systems

International Nuclear Information System (INIS)

Angrisani, L; Vadursi, M

2008-01-01

Data acquisition systems (DAS) play a fundamental role in a lot of modern measurement solutions. One of the parameters characterizing a DAS is its maximum sample rate, which imposes constraints on the signals that can be alias-free digitized. Bandpass sampling theory singles out separated ranges of admissible sample rates, which can be significantly lower than carrier frequency. But, how to choose the most convenient sample rate according to the purpose at hand? The paper proposes a method for the automatic selection of the optimal sample rate in measurement applications involving bandpass signals; the effects of sample clock instability and limited resolution are also taken into account. The method allows the user to choose the location of spectral replicas of the sampled signal in terms of normalized frequency, and the minimum guard band between replicas, thus introducing a feature that no DAS currently available on the market seems to offer. A number of experimental tests on bandpass digitally modulated signals are carried out to assess the concurrence of the obtained central frequency with the expected one

A review and empirical study of the composite scales of the Das-Naglieri cognitive assessment system.

Science.gov (United States)

McCrea, Simon M

2009-01-01

Alexander Luria's model of the working brain consisting of three functional units was formulated through the examination of hundreds of focal brain-injury patients. Several psychometric instruments based on Luria's syndrome analysis and accompanying qualitative tasks have been developed since the 1970s. In the mid-1970s, JP Das and colleagues defined a specific cognitive processes model based directly on Luria's two coding units termed simultaneous and successive by studying diverse cross-cultural, ability, and socioeconomic strata. The cognitive assessment system is based on the PASS model of cognitive processes and consists of four composite scales of Planning-Attention-Simultaneous-Successive (PASS) devised by Naglieri and Das in 1997. Das and colleagues developed the two new scales of planning and attention to more closely model Luria's theory of higher cortical functions. In this paper a theoretical review of Luria's theory, Das and colleagues elaboration of Luria's model, and the neural correlates of PASS composite scales based on extant studies is summarized. A brief empirical study of the neuropsychological specificity of the PASS composite scales in a sample of 33 focal cortical stroke patients using cluster analysis is then discussed. Planning and simultaneous were sensitive to right hemisphere lesions. These findings were integrated with recent functional neuroimaging studies of PASS scales. In sum it was found that simultaneous is strongly dependent on dual bilateral occipitoparietal interhemispheric coordination whereas successive demonstrated left frontotemporal specificity with some evidence of interhemispheric coordination across the prefrontal cortex. Hence, support for the validity of the PASS composite scales was found as well as for the axiom of the independence of code content from code type originally specified in 1994 by Das, Naglieri, and Kirby.

Distributed Acoustic Sensing (DAS) is creating a "field as laboratory" capability for seismic monitoring of subsurface changes. By providing unprecedented spatial and temporal sampling at a relatively low cost, DAS enables field-scale seismic monitoring to have durations and temporal resolutions that are comparable to those of laboratory experiments. Here we report on seismic processing approaches developed during data analyses of three case studies all using DAS-enabled seismic monitoring with applications ranging from shallow permafrost to deep reservoirs: (1) 10-hour downhole monitoring of cement curing at Otway, Australia; (2) 2-month surface monitoring of controlled permafrost thaw at Fairbanks, Alaska; (3) multi-month downhole and surface monitoring of carbon sequestration at Decatur, Illinois. We emphasize the data management and processing components relevant to DAS-based seismic monitoring, which include scalable approaches to data management, pre-processing, denoising, filtering, and wavefield decomposition. DAS has dramatically increased the data volume to the extent that terabyte-per-day data loads are now typical, straining conventional approaches to data storage and processing. To achieve more efficient use of disk space and network bandwidth, we explore improved file structures and data compression schemes. Because noise floor of DAS measurements is higher than that of conventional sensors, optimal processing workflow involving advanced denoising, deconvolution (of the source signatures), and stacking approaches are being established to maximize signal content of DAS data. The resulting workflow of data management and processing could accelerate the broader adaption of DAS for continuous monitoring of critical processes.

Music in Dementia Assessment Scales (MiDAS), an observational outcome measure for music therapy with people with moderate to severe dementia, was developed from qualitative data of focus groups and interviews. Expert and peer consultations were conducted at each stage of the scale development to maximize its content validity. This study aimed to evaluate the psychometric properties of MiDAS. Care home residents with dementia attended weekly group music therapy for up to ten sessions. Music therapists and care home staff were requested to complete weekly MiDAS ratings. The Quality of Life Scale (QoL-AD) was completed at three time-points. A total of 629 (staff = 306, therapist = 323) MiDAS forms were completed. The statistical analysis revealed that MiDAS has high therapist inter-rater reliability, low staff inter-rater reliability, adequate staff test-retest reliability, adequate concurrent validity, and good construct validity. High factor loadings between the five MiDAS Visual Analogue Scale (VAS) items, levels of Interest, Response, Initiation, Involvement, and Enjoyment, were found. This study indicates that MiDAS has good psychometric properties despite the small sample size. Future research with a larger sample size could provide a more in-depth psychometric evaluation, including further exploration of the underlying factors. MiDAS provides a measure of engagement with musical experience and offers insight into who is likely to benefit on other outcomes such as quality of life or reduction in psychiatric symptoms.

Integration of DAS (distributed acoustic sensing) vertical seismic profile and geostatistically modeled lithology data to characterize an enhanced geothermal system.

Science.gov (United States)

Cronin, S. P.; Trainor Guitton, W.; Team, P.; Pare, A.; Jreij, S.; Powers, H.

2017-12-01

In March 2016, a 4-week field data acquisition took place at Brady's Natural Lab (BNL), an enhanced geothermal system (EGS) in Fallan, NV. During these 4 weeks, a vibe truck executed 6,633 sweeps, recorded by nodal seismometers, horizontal distributed acoustic sensing (DAS) cable, and 400 meters of vertical DAS cable. DAS provides lower signal to noise ratio than traditional geophones but better spatial resolution. The analysis of DAS VSP included Fourier transform, and filtering to remove all up-going energy. Thus, allowing for accurate first arrival picking. We present an example of the Gradual Deformation Method (GDM) using DAS VSP and lithological data to produce a distribution of valid velocity models of BNL. GDM generates continuous perturbations of prior model realizations seeking the best match to the data (i.e. minimize the misfit). Prior model realizations honoring the lithological data were created using sequential Gaussian simulation, a commonly used noniterative geostatistical method. Unlike least-squares-based methods of inversion, GDM readily incorporates a priori information, such as a variogram calculated from well-based lithology information. Additionally, by producing a distribution of models, as opposed to one optimal model, GDM allows for uncertainty quantification. This project aims at assessing the integrated technologies ability to monitor changes in the water table (possibly to one meter resolution) by exploiting the dependence of seismic wave velocities on water saturation of the subsurface. This project, which was funded in part by the National Science Foundation, is a part of the PoroTomo project, funded by a grant from the U.S. Department of Energy.

The Microbial Database for Activated Sludge (MiDAS) field guide is a freely available online resource linking the identity of abundant and process critical microorganisms in activated sludge wastewater treatment systems to available data related to their functional importance. Phenotypic properties of some of these genera are described, but most are known only from sequence data. The MiDAS taxonomy is a manual curation of the SILVA taxonomy that proposes a name for all genus-level taxa observed to be abundant by large-scale 16 S rRNA gene amplicon sequencing of full-scale activated sludge communities. The taxonomy can be used to classify unknown sequences, and the online MiDAS field guide links the identity to the available information about their morphology, diversity, physiology and distribution. The use of a common taxonomy across the field will provide a solid foundation for the study of microbial ecology of the activated sludge process and related treatment processes. The online MiDAS field guide is a collaborative workspace intended to facilitate a better understanding of the ecology of activated sludge and related treatment processes--knowledge that will be an invaluable resource for the optimal design and operation of these systems. © The Author(s) 2015.

"Das Konkrete ist das Abstrakte, an das man sich schließlich gewöhnt hat." (Laurent Schwartz) Über den Ablauf des mathematischen Verstehens

Science.gov (United States)

Lowsky, Martin

Die im Titel genannte Aussage findet sich in den Lebenserinnerungen von Laurent Schwartz (1915-2002), einem der fruchtbarsten Mathematiker, Mitglied der Gruppe Bourbaki. Im Original lautet die Aussage: "un objet concret est un objet abstrait auquel on a fini par s'habituer." Schwartz erläutert sie am Beispiel des Integrals über {e^{-1/2{x^2}}} , das den Wert Wurzel aus 2π hat und in dem sich also die Zahlen e und π verknüpfen. Was Schwartz aber vor allem ausdrücken will, ist dies: Das mathematische Verständnisd geht langsam vor sich und es bedarf der Anstrengung. "Es ist eine Frage der Zeit und der Energie", sagt Schwartz, und gerade dies mache es so schwer, die höhere Mathematik unter das Volk zu bringen. Das Lernen und Lehren von Mathematik laufe eben mühevoll und langsam ab.

Vehicle based localization system for locomotives on the base of slip depending distance measurment; Fahrzeugautarkes Ortungssystem fuer Lokomotiven auf der Basis schlupfbehafteter Wegmessung

More and more railway operating companies use telematic systems for a more efficient use of their infrastructure in order to improve their traffic products. Almost every telematic task requires a vehicle localization. Thus a high demand for localization systems emerges. In many cases the high cost of investment and a growing attentiveness for cost efficiency hinders the implementation of high performance systems. This thesis describes the development and testing of a vehicle based localization system for locomotives. The method is based on a distance measurement on the propelled axles. The systems estimates the wheel slip depending on the momentary traction force and vehicle speed and corrects the original measurement. The special thing about this system is, that it uses only the existing technical infrastructure of locomotives. So there is no need to provide costly extra sensors. Thus the system could be installed with little preparation at low cost in almost all locomotives of German Rail. The vehicle localization was tested as part of a one-year pilot operation of a computer based energy efficient train control system (Energiesparende Fahrweise: ESF) of German Rail. During this time the system proofed a significant reduction of the distance measurement error caused by the wheel slip during regular train operation. Hence a wide range of non-safety-relevant telematic tasks would be able to use the system. This compose gives a review of important terms and aspects of localization and the characteristic connection of the friction coefficient and wheel slip of railway vehicles. The compose continues with the description of the development and testing of the system. The evaluation of the measurements and the resulting performance and quality of the localization information show the suitability of the system for an operational vehicle localization of medium quality at low cost.

Radioisotopes are used now in some areas of the industry. For quality control purposes, they are used in non-destructive analysis (NDA) which is applied to the materials examination verifying if they are adequate to the patterns demanded by technical rules or the market. Gamma, beta or neutron radiation sources may be used to do NDA, depending on material to be analyzed and the industrial process. In this work, the study of measurement system applied to quality control area was conceived and, in the evaluation of the material in test, a radioactive beta source was used. A system was designed and mounted, using a plastic scintillator detector developed in the laboratories of the Centro de Tecnologia das Radiacoes from IPEN-CNEN/SP. Two beta sources were used in the operational test: 90 Sr/ 90 Y and 204 Tl. Measures were obtained using several paper samples with different superficial density in g/m 2 . With the results, an equation correlating the relative activity with the superficial density in g/m 2 was established. (author)

Electricity supply companies have a big advantage: They continuously measure consumer behaviour, thanks to network control systems, centralised multistations and remote meter reading. However, they do not combine this data on a consistent basis frequently enough to be able to draw valuable consequences for sales and marketing. One of the few exceptions in the Unterfraenkische Ueberlandzentrale, UUeZ (Lower Franconian Electricity Supply Company). At UUeZ, the meter readings from each individual load profile meter built into the plant of customers with special contracts, are fed together into a `cockpit`. Assisted by a Data-Warehouse-Solution from FrankenData GmbH, an ingenious information system that enables longterm trends and optimisation potential to be recognised immediately was implemented. The benefits for electricity suppliers: A constant load factor and reduction of peaks, improved customer contact as well as more precise information at negotiations and therefore more advantageous contracts. Customers also benefit from the new system: They receive more economical tariffs and detailed reports about their consumer behaviour, which they can then optimise by taking appropriate measures.

GenExp: an interactive web-based genomic DAS client with client-side data rendering.

Directory of Open Access Journals (Sweden)

Bernat Gel Moreno

Full Text Available BACKGROUND: The Distributed Annotation System (DAS offers a standard protocol for sharing and integrating annotations on biological sequences. There are more than 1000 DAS sources available and the number is steadily increasing. Clients are an essential part of the DAS system and integrate data from several independent sources in order to create a useful representation to the user. While web-based DAS clients exist, most of them do not have direct interaction capabilities such as dragging and zooming with the mouse. RESULTS: Here we present GenExp, a web based and fully interactive visual DAS client. GenExp is a genome oriented DAS client capable of creating informative representations of genomic data zooming out from base level to complete chromosomes. It proposes a novel approach to genomic data rendering and uses the latest HTML5 web technologies to create the data representation inside the client browser. Thanks to client-side rendering most position changes do not need a network request to the server and so responses to zooming and panning are almost immediate. In GenExp it is possible to explore the genome intuitively moving it with the mouse just like geographical map applications. Additionally, in GenExp it is possible to have more than one data viewer at the same time and to save the current state of the application to revisit it later on. CONCLUSIONS: GenExp is a new interactive web-based client for DAS and addresses some of the short-comings of the existing clients. It uses client-side data rendering techniques resulting in easier genome browsing and exploration. GenExp is open source under the GPL license and it is freely available at http://gralggen.lsi.upc.edu/recerca/genexp.

Common Data Acquisition Systems (DAS) Software Development for Rocket Propulsion Test (RPT) Test Facilities

The advent of the commercial space launch industry and NASA's more recent resumption of operation of Stennis Space Center's large test facilities after thirty years of contractor control resulted in a need for a non-proprietary data acquisition systems (DAS) software to support government and commercial testing. The software is designed for modularity and adaptability to minimize the software development effort for current and future data systems. An additional benefit of the software's architecture is its ability to easily migrate to other testing facilities thus providing future commonality across Stennis. Adapting the software to other Rocket Propulsion Test (RPT) Centers such as MSFC, White Sands, and Plumbrook Station would provide additional commonality and help reduce testing costs for NASA. Ultimately, the software provides the government with unlimited rights and guarantees privacy of data to commercial entities. The project engaged all RPT Centers and NASA's Independent Verification & Validation facility to enhance product quality. The design consists of a translation layer which provides the transparency of the software application layers to underlying hardware regardless of test facility location and a flexible and easily accessible database. This presentation addresses system technical design, issues encountered, and the status of Stennis development and deployment.

Morphological diversity of fish along the rio das Velhas, Minas Gerais, Brazil

Directory of Open Access Journals (Sweden)

Nara Tadini Junqueira

Full Text Available The rio das Velhas, located in central Minas Gerais State (Brazil, is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two dimensions of the PCA suggest that the morphological volume occupied by the headwaters region is smaller than the other sections, because of the low richness of the site. However, morphological hypervolumes of the four reaches analyzed by Euclidean distances were not statistically different. The results indicated that only the density of morphological types increases along the rio das Velhas, and there is no difference between the headwaters and upper courses. Therefore, in order to use functional groups related to the morphology of the species as tools to take measures for the conservation and revitalization of the rio das Velhas, it is necessary analyze the density of species within these groups, as well as their composition.

Background Naturalistic driving studies, designed to objectively assess driving behavior and outcomes, are conducted by equipping vehicles with dedicated instrumentation (eg, accelerometers, gyroscopes, Global Positioning System, and cameras) that provide continuous recording of acceleration, location, videos, and still images for eventual retrieval and analyses. However, this research is limited by several factors: the cost of equipment installation; management and storage of the large amounts of data collected; and data reduction, coding, and analyses. Modern smartphone technology includes accelerometers built into phones, and the vast, global proliferation of smartphones could provide a possible low-cost alternative for assessing kinematic risky driving. Objective We evaluated an in-house developed iPhone app (gForce) for detecting elevated g-force events by comparing the iPhone linear acceleration measurements with corresponding acceleration measurements obtained with both a custom Android app and the in-vehicle miniDAS data acquisition system (DAS; Virginia Tech Transportation Institute). Methods The iPhone and Android devices were dashboard-mounted in a vehicle equipped with the DAS instrumentation. The experimental protocol consisted of driving maneuvers on a test track, such as cornering, braking, and turning that were performed at different acceleration levels (ie, mild, moderate, or hard). The iPhone gForce app recorded linear acceleration (ie, gravity-corrected). The Android app recorded gravity-corrected and uncorrected acceleration measurements, and the DAS device recorded gravity-uncorrected acceleration measurements. Lateral and longitudinal acceleration measures were compared. Results The correlation coefficients between the iPhone and DAS acceleration measurements were slightly lower compared to the correlation coefficients between the Android and DAS, possibly due to the gravity correction on the iPhone.

For over 14 years the University of Iowa Radio and Plasma Wave Group has utilized a network transparent data streaming and visualization system for most daily data review and collaboration activities. This system, called Das2, was originally designed in support of the Cassini Radio and Plasma Wave Science (RPWS) investigation, but is now relied on for daily review and analysis of Voyager, Polar, Cluster, Mars Express, Juno and other mission results. In light of current efforts to promote automatic data distribution in space physics it seems prudent to provide an overview of our open source Das2 programs and interface definitions to the wider community and to recount lessons learned. This submission will provide an overview of interfaces that define the system, describe the relationship between the Das2 effort and Autoplot and will examine handling Cassini RPWS Wideband waveforms and dynamic spectra as examples of dealing with long time-series data sets. In addition, the advantages and limitations of the current Das2 tool set will be discussed, as well as lessons learned that are applicable to other data sharing initiatives. Finally, plans for future developments including improved catalogs to support 'no-software' data sources and redundant multi-server fail over, as well as new adapters for CSV (Comma Separated Values) and JSON (Javascript Object Notation) output to support Cassini closeout and the HAPI (Heliophysics Application Programming Interface) initiative are outlined.

Em seguida estendemos a abordagem para apoiar duas decisões combinadas: a localização das bases de ambulâncias e o dimensionamento das regiões de cobertura de cada base na rodovia. Por exemplo, a abordagem permite determinar os locais para posicionar as bases de ambulâncias e dimensionar os tamanhos das suas áreas de atuação, tais que minimizem o tempo médio de resposta aos usuários e/ou o desbalanceamento das cargas de trabalho das ambulâncias do sistema. Para ilustrar a aplicação dos métodos propostos, analisamos os resultados de dois estudos de caso em rodovias brasileiras.In this paper we combine extensions of the hypercube queueing model with genetic algorithms to optimize the configuration and operation of emergency medical systems on highways. Initially we present a method to locate the ambulance bases along the highway so that the main system performance measures are optimized. Then we extend the approach to support combined decisions: the location of ambulance bases and the districting of the covering regions of each base on the highway. For instance, the approach can search for locals to place the ambulance bases and determine the sizes of their operation areas, such that the mean user response time and/or the ambulance workload imbalance are minimized. To illustrate the application of the proposed methods, we analyze the results of two case studies of Brazilian highways.

Legal system of nuclear waste disposal. Das System der atomaren Entsorgungsregelung

Energy Technology Data Exchange (ETDEWEB)

Dauk, W

1983-01-01

This doctoral thesis presents solutions to some of the legal problems encountered in the interpretation of the various laws and regulations governing nuclear waste disposal, and reveals the legal system supporting the variety of individual regulations. Proposals are made relating to modifications of problematic or not well defined provisions, in order to contribute to improved juridical security, or inambiguity in terms of law. The author also discusses the question of the constitutionality of the laws for nuclear waste disposal. Apart from the responsibility of private enterprise to contribute to safe treatment or recycling, within the framework of the integrated waste management concept, and apart from the Government's responsibility for interim or final storage of radioactive waste, there is a third possibility included in the legal system for waste management, namely voluntary measures taken by private enterprise for radioactive waste disposal. The licence to be applied for in accordance with section 3, sub-section (1) of the Radiation Protection Ordinance is interpreted to pertain to all measures of radioactive waste disposal, thus including final storage of radioactive waste by private companies. Although the terminology and systematic concept of nuclear waste disposal are difficult to understand, there is a functionable system of legal provisions contained therein. This system fits into the overall concept of laws governing technical safety and safety engineering.

There is a need to develop an outcome measure specific to music therapy in dementia that reflects a holistic picture of the therapy process and outcome. This study aimed to develop a clinically relevant and scientifically robust music therapy outcome measure incorporating the values and views of people with dementia. Focus groups and interviews were conducted to obtain qualitative data on what music meant to people with dementia and the observed effects of music. Expert and peer consultations were conducted at each stage of the measure development to maximise its content validity. The new measure was field-tested by clinicians in a care home. Feedback from the clinicians and music therapy experts were incorporated during the review and refinement process of the measure. A review of the existing literature, the experiential results and the consensus process enabled the development of the new outcome measure "Music in Dementia Assessment Scales (MiDAS)". Analysis of the qualitative data identified five key areas of the impact of music on people with dementia and they were transformed as the five Visual Analogue Scale (VAS) items: levels of Interest, Response, Initiation, Involvement and Enjoyment. MiDAS comprises the five VAS items and a supplementary checklist of notable positive and negative reactions from the individual. This study demonstrates that it is possible to design and develop an easy to apply and rigorous quantitative outcome measure which has a high level of clinical relevance for people with dementia, care home staff and music therapists.

Naturalistic driving studies, designed to objectively assess driving behavior and outcomes, are conducted by equipping vehicles with dedicated instrumentation (eg, accelerometers, gyroscopes, Global Positioning System, and cameras) that provide continuous recording of acceleration, location, videos, and still images for eventual retrieval and analyses. However, this research is limited by several factors: the cost of equipment installation; management and storage of the large amounts of data collected; and data reduction, coding, and analyses. Modern smartphone technology includes accelerometers built into phones, and the vast, global proliferation of smartphones could provide a possible low-cost alternative for assessing kinematic risky driving. We evaluated an in-house developed iPhone app (gForce) for detecting elevated g-force events by comparing the iPhone linear acceleration measurements with corresponding acceleration measurements obtained with both a custom Android app and the in-vehicle miniDAS data acquisition system (DAS; Virginia Tech Transportation Institute). The iPhone and Android devices were dashboard-mounted in a vehicle equipped with the DAS instrumentation. The experimental protocol consisted of driving maneuvers on a test track, such as cornering, braking, and turning that were performed at different acceleration levels (ie, mild, moderate, or hard). The iPhone gForce app recorded linear acceleration (ie, gravity-corrected). The Android app recorded gravity-corrected and uncorrected acceleration measurements, and the DAS device recorded gravity-uncorrected acceleration measurements. Lateral and longitudinal acceleration measures were compared. The correlation coefficients between the iPhone and DAS acceleration measurements were slightly lower compared to the correlation coefficients between the Android and DAS, possibly due to the gravity correction on the iPhone. Averaging the correlation coefficients for all maneuvers, the longitudinal and

Tripti, K; Shardendu

2016-08-01

The toxic characteristics of arsenic species, As(V) and As(III) result in ecological risks. Arsenic tolerant bacterium was isolated and identified as the Bacillus licheniformis DAS-2 through 16SrDNA sequencing. B. licheniformis DAS-2 was efficient to tolerate and remove both the As(V)[MIC 8mM] and As(III)[MIC 6mM] from the growth medium. The potential for the removal/uptake of arsenic from the 3, 5 and 7mM As(V) enriched growth media was 100%, 60% and 35% respectively and from the 1, 3 and 5mM As(III) enrichment it was 100%, 99% and 58% respectively at neutral pH. 80% of uptake As(V) was reduced to As(III) in 3mM As(V) enrichment which was gradually decreased to only 17% at 7mM As(V) enrichment at neutral pH. The arsenic toxicity in B. licheniformis DAS-2 was found modulated by pH and was examined through alteration in growth, uptake/removal, reduction and measurement of chemical toxicity.

The short-range flame burner and the KOALA reactor of DMT are experimental facilities for realistic simulation of coal conversion processes at high temperatures and pressures in atmospheric conditions. The TOSCA system enable measurements of temperatures, sizes, shapes and velocities of the fuel particles, which serve as a basis for a three-dimensional simulation model of coal combustion. In the future, further parameter studies will deepen the present knowledge of coal dust combustion under pressure and enable optimisation of the numerical models for simulation of industrial-scale systems for coal dust combustion under pressure. [Deutsch] Mit dem Flachflammenbrenner und dem KOALA-Reaktor der DMT stehen Versuchsapparaturen zur Verfuegung, mit deren Hilfe die Kohleumwandlungsprozesse bei hohen Temperaturen unter Druck und unter atmosphaerischen Bedingungen realistisch wiedergegeben werden. Das TOSCA-System erlaubt dabei die Bestimmung von Temperaturen, Groessen, Formen und Geschwindigkeiten der Brennstoffpartikel. Diese Daten liefern die Grundlage fuer die Erstellung eines dreidimensionalen Simulationsmodells zur Modellierung der Kohleverbrennung. In Zukunft werden weitere Parameterstudien das Verstaendnis der Kohlenstaubdruckverbrennung vertiefen und ein Optimierung der numerischen Modelle ermoeglichen, so dass die Simulation grosstechnischer Kohlenstaubdruckverbrennungsanlagen realisiert werden kann.

Full Text Available The rio das Velhas, located in central Minas Gerais State (Brazil, is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two dimensions of the PCA suggest that the morphological volume occupied by the headwaters region is smaller than the other sections, because of the low richness of the site. However, morphological hypervolumes of the four reaches analyzed by Euclidean distances were not statistically different. The results indicated that only the density of morphological types increases along the rio das Velhas, and there is no difference between the headwaters and upper courses. Therefore, in order to use functional groups related to the morphology of the species as tools to take measures for the conservation and revitalization of the rio das Velhas, it is necessary analyze the density of species within these groups, as well as their composition.O rio das Velhas, localizado na região central do estado de Minas Gerais (Brasil, é o mais extenso tributário do rio São Francisco.

A eficiência na extração está relacionada ao aquecimento e ao teor de água das sementes. Desta forma, a determinação de um modelo de secagem que represente satisfatoriamente os dados experimentais é de suma importância para minimizar as alterações promovidas pelo processo obtendo-se, consequentemente, produto de qualidade. O objetivo do trabalho foi descrever a cinética de secagem das sementes de andiroba, tal como ajustar os modelos matemáticos aos dados experimentais usando-se secador solar. Foi utilizado, como critério do ajuste dos modelos matemáticos, o coeficiente de determinação, a magnitude do erro médio relativo e o desvio-padrão da estimativa. A secagem em menor tempo (14 dias da Carapa surinamensis para atingir o teor de água de equilíbrio (12,28% se deve, possivelmente, ao menor tamanho das sementes e à maior quantidade de óleo em relação à Carapa guianensis. O modelo Logarítmico e o de Midilli et al. foram os que melhor se ajustaram aos dados experimentais para as sementes das duas espécies de andiroba.

2015-01-01

There is a need to develop an outcome measure specific to music therapy in dementia that reflects a holistic picture of the therapy process and outcome. This study aimed to develop a clinically relevant and scientifically robust music therapy outcome measure incorporating the values and views of people with dementia. Focus groups and interviews were conducted to obtain qualitative data on what music meant to people with dementia and the observed effects of music. Expert and peer consultations were conducted at each stage of the measure development to maximise its content validity. The new measure was field-tested by clinicians in a care home. Feedback from the clinicians and music therapy experts were incorporated during the review and refinement process of the measure. A review of the existing literature, the experiential results and the consensus process enabled the development of the new outcome measure “Music in Dementia Assessment Scales (MiDAS)”. Analysis of the qualitative data identified five key areas of the impact of music on people with dementia and they were transformed as the five Visual Analogue Scale (VAS) items: levels of Interest, Response, Initiation, Involvement and Enjoyment. MiDAS comprises the five VAS items and a supplementary checklist of notable positive and negative reactions from the individual. This study demonstrates that it is possible to design and develop an easy to apply and rigorous quantitative outcome measure which has a high level of clinical relevance for people with dementia, care home staff and music therapists.

Este trabalho procura racionalizar o referido resultado revisitando as estimativas das importações do país desagregadas por “categoria de uso”. Os resultados reportados sugerem que a baixa elasticidade-preço das importações agregadas reflete fundamentalmente a baixa elasticidade-preço das importações de combustíveis, bens intermediários e de alguns tipos de serviços - notadamente, transporte, aluguel de equipamentos e pagamentos de royalties - produtos que, somados, respondem por pouco menos de dois terços do total importado. Isso ocorre porque vários desses produtos têm pouca ou nenhuma possibilidade de substituição por similares nacionais, devido principalmente a deficiências estruturais na oferta nacional.

After extensive trials in the course of a project study Fraenkische Ueberlandwerk AG (FUeW) has decided to introduce a wireless centralised ripple control system for its entire service area. The system will initially be used for synchronising and parameterising multiple tariff meters. Ripple control receivers are to take over the function formerly perfomed by switch clocks of switching between night and day tariff. FUeW`s decision was essentially motivated by the proven reliability of wireless centralised ripple control systems and by the economic advantages of this modern technology. (orig.)

Reactions of an alkaline earth metal with a SiCl{sub 4}-H{sub 2} result in a quaternary system with a metastable quaternary phase which separates into the metal chloride and nanocrystalline silicon upon cooling. The present study was dedicated to a making a detailed characterisation of the quaternary phase. For this purpose the properties of the quaternary system were derived from those of the six binary and four ternary systems. The first ever characterisation of the surface by means of photoelectron spectroscopy was undertaken. It also proved possible for the first time to follow the formation reaction by measuring the potential difference across the reaction system. Using the results of the characterisation the author presents first steps towards identifying the formation mechanism involved.

System 8400 is an advanced system for measurement of gas and liquid pressure, along with a variety of other parameters, including voltage, frequency and digital inputs. System 8400 offers exceptionally high speed data acquisition through parallel processing, and its modular design allows expansion from a relatively inexpensive entry level system by the addition of modular Input Units that can be installed or removed in minutes. Douglas Juanarena was on the team of engineers that developed a new technology known as ESP (electronically scanned pressure). The Langley ESP measurement system was based on miniature integrated circuit pressure-sensing transducers that communicated pressure information to a minicomputer. In 1977, Juanarena formed PSI to exploit the NASA technology. In 1978 he left Langley, obtained a NASA license for the technology, introduced the first commercial product, the 780B pressure measurement system. PSI developed a pressure scanner for automation of industrial processes. Now in its second design generation, the DPT-6400 is capable of making 2,000 measurements a second and has 64 channels by addition of slave units. New system 8400 represents PSI's bid to further exploit the 600 million U.S. industrial pressure measurement market. It is geared to provide a turnkey solution to physical measurement.

Performance of broiler chickens fed diets containing DAS-68416-4 soybean meal.

Herman, Rod A; Dunville, Christina M; Juberg, Daland R; Fletcher, Dale W; Cromwell, Gary L

Broiler chickens are a fast growing monogastric animal commonly used to evaluate the equivalence between transgenic and non-transgenic grains as part of the human safety assessment process. While commonly viewed like other livestock feeding trials, such studies are performed with transgenic crops with input traits (that are not designed to improve nutrition) to aid regulatory authorities in evaluating safety. Studies of this type are actually more similar to toxicology studies in purpose, with sensitive endpoints like growth used to detect metabolic perturbations. DAS-68416-4 soybean expresses the aryloxyalkanoate dioxygenase-12 (AAD-12) enzyme which inactivates 2,4-diclorophenoxyacetic acid (2,4-D) and provides DAS-68416-4 soybeans tolerance to this herbicide. DAS-68416-4 also expresses the phosphinothricin acetyltransferase (PAT) enzyme from Streptomyces viridochromogenes which confers tolerance to glufosinate-ammonium herbicides. A 6-week broiler study was conducted with diets containing toasted DAS-68416-4 soybean meal (40, 36, and 32% in starter, grower and finisher diets, respectively) to evaluate nutritional wholesomeness and safety compared with conventional comparators. Toasting soybean meal is required to inactivate endogenous antinutrients making soybean suitable for consumption by monogastric animals like broiler chickens. Toasting was found to denature both the AAD-12 and PAT proteins rendering them non-detectable by enzyme linked immunosorbent assays. Broiler growth and performance parameters were measured over a 6-week period of exposure to diets containing different sources of toasted soybean meal, and results indicate that DAS-68416-4 soybean is nutritionally equivalent to non-transgenic soybean.

A mobile environmental laboratory was developed and successfully tested. This system is used for the remote emissions and ambient air measurements. The key instrument of this laboratory is the Kayser-Threde double pendulum interferometer K300, a field proven FT-IR system for remote emission and ambient air measurements. In addition, the laboratory contains conventional ambient air sensors and a battery system for current source free usage. Basic scientific research was necessary for the development of appropriate analysis methods for quantitative detection of emissions from smoke stacks when doing remote sensing, as well as for ambient air measurements. The mobile laboratory was used in a number of measurement campaigns. The following gaseous specimens could quantitatively analyzed: H{sub 2}O, CO{sub 2}, CO, NO, NO{sub 2}, N{sub 2}O, SO{sub 2}, CH{sub 4}, HCl, HCHO and total hydrocarbons (THC). The correspondence between the K300 remote sensing results with the measured values taken by conventional reference systems was good to excellent, in many cases considerably better than expected. (orig.) [Deutsch] Es wurde ein Umwelt-Messfahrzeug entwickelt und erfolgreich erprobt, das fuer die Fernerkundungsmessung von Emissionen und Immissionen eingesetzt werden kann.

The beam diagnosis system for ELSA. Das Strahldiagnosesystem fuer ELSA

Energy Technology Data Exchange (ETDEWEB)

Schillo, M.

1991-10-01

A beam diagnostic system, which is based on capacitive beam-position monitors combined with fast electronics, has been developed for the Bonn Electron Stretcher Accelerator ELSA. The position signal of each monitor is digitized at an adjustable sampling rate and the most recent 8192 position and intensity values are buffered. This allows a wide range of different beam diagnostic measurements. The main purpose is the closed-orbit correction, which can be carried out on various time scales. To optimize the duty factor of the extracted beam, the system can also be used as a fast relative intensity monitor resolving the intensity distribution of the bunches or of the injected beam. It is designed to support betatron tune and phase measurements with very high accuracy, offering the choice to select any of the beam position monitors. This enables the measuring of many optical parameters. Furthermore any pair of suitable monitors can be used for experimental particle tracking or phase space measurements. (orig.).

The proposed activity provides the description of the Data Acquisition System for Tank 241-AZ-101. This description is documented in HNF-5572, Tank 241-AZ-101 Waste Retrieval Data Acquisition System (DAS). This activity supports the planned mixer pump tests for Tank 241-AZ-101. Tank 241-AZ-101 has been selected for the first full-scale demonstration of a mixer pump system. The tank currently holds over 960,000 gallons of neutralized current acid waste, including approximately 12.7 inches of settling solids (sludge) at the bottom of the tank. As described in Addendum 4 of the FSAR (LMHC 2000a), two 300 HP mixer pumps with associated measurement and monitoring equipment have been installed in Tank 241-AZ-101. The purpose of the Tank 241-AZ-101 retrieval system Data Acquisition System (DAS) is to provide monitoring and data acquisition of key parameters in order to confirm the effectiveness of the mixer pumps utilized for suspending solids in the tank. The suspension of solids in Tank 241-AZ-101 is necessary for pretreatment of the neutralized current acid waste and eventual disposal as glass via the Hanford Waste Vitrification Plant. HNF-5572 provides a basic description of the Tank 241-AZ-101 retrieval system DAS, including the field instrumentation and application software. The DAS is provided to fulfill requirements for data collection and monitoring. This document is not an operations procedure or is it intended to describe the mixing operation. This USQ screening provides evaluation of HNF-5572 (Revision 1) including the changes as documented on ECN 654001. The changes include (1) add information on historical trending and data backup, (2) modify DAS I/O list in Appendix E to reflect actual conditions in the field, and (3) delete IP address in Appendix F per Lockheed Martin Services, Inc. request

Full Text Available Os estudos sobre o comportamento das aves, principalmente as galinhas, datam de 1912, quando o gênero Gallus passou a ser estudado com mais intensidade na área da Genética. Tais estudos eram simplesmente filosóficos até o início da década de 80, quando uma nova era da produção industrial avícola surgiu, objetivando um maior volume de produção econômica em todas as áreas de exploração. Esse objetivo reativou de maneira científica os estudos de comportamento das aves face à tecnologia de produção empregada nos sistemas de exploração, tornando-os mais acentuados já na década de 90, culminando com um simpósio internacional realizado nos Estados Unidos onde foram traçados os objetivos ou linhas de pesquisas na exploração avícola. O intuito era evitar problemas com os movimentos ambientalistas, traçando novos rumos para uma produção eficiente sem interferir no comportamento das aves já no início do novo milênio. Esta revisão, tem como objetivo principal uma análise científica e filosófica sobre o comportamento das aves em diversos métodos de exploração.Studies on poultry behavior initiated in 1972, at that time, fowls from Gallus domesticus species were the most important animal for the initial studies of Genetic. Since then, just the philosophical concepts where involved in those studies. However, at the beginning of 80 decade, these studies were intensified taking into account technological approaches for an economical industrial poultry production. Meanwhile, the reactions from activists involved in the behavior of the animal subjected to production became more strong at the beginning of 90's as well as those studies on chicken behavior. Finally, in 1998, an international symposium, promoted by chicken behavior scientists were held in the United States, in order to establish new methods of exploitation of poultry without interfering in its normal behavior, at the beginning of new millenium.

Wastewater is increasingly viewed as a resource, with anaerobic digester technology being routinely implemented for biogas production. Characterising the microbial communities involved in wastewater treatment facilities and their anaerobic digesters is considered key to their optimal design and operation. Amplicon sequencing of the 16S rRNA gene allows high-throughput monitoring of these systems. The MiDAS field guide is a public resource providing amplicon sequencing protocols and an ecosystem-specific taxonomic database optimized for use with wastewater treatment facility samples. The curated taxonomy endeavours to provide a genus-level-classification for abundant phylotypes and the online field guide links this identity to published information regarding their ecology, function and distribution. This article describes the expansion of the database resources to cover the organisms of the anaerobic digester systems fed primary sludge and surplus activated sludge. The updated database includes descriptions of the abundant genus-level-taxa in influent wastewater, activated sludge and anaerobic digesters. Abundance information is also included to allow assessment of the role of emigration in the ecology of each phylotype. MiDAS is intended as a collaborative resource for the progression of research into the ecology of wastewater treatment, by providing a public repository for knowledge that is accessible to all interested in these biotechnologically important systems. http://www.midasfieldguide.org. © The Author(s) 2017.

Das perguntas wittgensteinianas à pedagogia das competências: ou desmontando a caixa-preta de Perrenoud

Full Text Available Este artigo faz parte de uma pesquisa de mestrado que se propõe a analisar conceitos educacionais e curriculares por meio da filosofia da linguagem elaborada por Ludwig Wittgenstein. Dessa perspectiva, examinamos alguns pressupostos teóricos da chamada pedagogia das competências e interrogamos se esse modelo pedagógico, em nome de pretensa renovação do ensino, não encorajaria a reificação de conceitos mentais concernentes ao processo de aprendizagem. Com este fim, abordamos a reformulação que essa pedagogia oferece a respeito de conceitos como aprender, saber, compreender, destacando as ambiguidades daí decorrentes. Argumenta-se que é possível obter uma leitura mais rigorosa das suas propostas de modernização pedagógica se investigarmos o uso dado a esses conceitos nos jogos de linguagem em que eles são mobilizados. Wittgenstein, na segunda fase de sua produção intelectual, mostrou como a negligência linguística à dinâmica que dá significado aos conceitos e metáforas referentes à nossa vida mental fez com que diversas filosofias assumissem um perfil metafísico. Este artigo não apenas examina como um fenômeno análogo pode ocorrer no campo pedagógico, como também defende que as ferramentas analíticas construídas por Wittgenstein podem ser usadas contra os diferentes dogmatismos pedagógicos. Desse modo, o artigo aponta vias alternativas de problematização acerca do significado das reformas dos sistemas escolares que têm buscado fundamentos naquela pedagogia.

Testes estatísticos, multivariados e não paramétricos foram utilizados para avaliar 11 variáveis físicas, químicas e microbiológicas de 29 estações de monitoramento. Os resultados das análises de tendência Mann-Kendall/Sazonal de Mann-Kendall sugeriram que a maioria dos cursos d'água da região apresentam valores estáveis das variáveis ao longo do período estudado, com maiores alterações associadas a coliformes termotolerantes, demanda bioquímica de oxigênio (DBO, nitrato e índice de qualidade das águas (IQA, principalmente nas proximidades dos grandes centros urbanos. A análise de Cluster definiu três grandes grupos de estações de monitoramento, agrupadas segundo a qualidade de suas águas, correspondentes aos níveis de alta poluição, poluição moderada e baixa poluição. No entanto, ao longo de toda a sub-bacia, foi observada a degradação da qualidade da água durante o período estudado, principalmente relacionada ao lançamento de esgotos domésticos. Uma importante constatação foi a alteração da qualidade da água no baixo Rio das Velhas, apontada pela tendência de redução do IQA em estações localizadas nessa região, o que merece atenção dos órgãos governamentais para ações de manejo.

After several years of preparatory research and in cooperation with several universities and organisations, Rohloel-Aufsuchungs AG were successful in recycling not only the flushings but also the cuttings of the drilling process, i.e. there is no need for dumping the residues. This is important as the regional authorities in that region are highly reluctant to grant permits for constructing new landfills, owing to the fact that it is a region of freshwater reserves for a large part of Europe and also a region much frequented by tourists. The 'waste-free drilling concept' has been applied for almost one year now. Further optimisation measures are projected. [German] Der Rohoel-Aufsuchungs AG ist es nach mehrjaehrigen Vorarbeiten gemeinsam mit verschiedenen Universitaeten und Institutionen gelungen, nicht nur die gesamte Bohrspuelung sondern auch die im Zuge des Bohrprozesses anfallenden Cuttings einer vollstaendigen Wiederverwertung zuzufuehren: Durch eine triviale Veraenderung des Spuelungschemismus, die den vollstaendigen Ersatz von Kaliumchlorid durch Kaliumkarbonate vorsieht, konnte das Bohrklein vom ''Abfall'' zum ''Wirtschaftsgut'' augewertet werden. Mit diesem entscheidenden Schritt wird der Bau neuer Borschlammdeponien ueberfluessig, deren behoerdliche Genehmigung ohnehin als unwahrscheinlich angesehen werden muss, zumal in dieser Region Grundwasserreserven fuer einen Teil Europas liegen und der Tourismus zur Haupteinnahmequelle dieses Gebietes zaehlt. Das ''abfallfreie Bohrkonzept'' wird bei der Rohoel-Aufsuchungs AG seit nahezu einem Jahr erfolgreich umgesetzt. Weitere Optimierungsschritte sind noch geplant. (orig.)

The advent of the commercial space launch industry and NASA's more recent resumption of operation of Stennis Space Center's large test facilities after thirty years of contractor control resulted in a need for a non-proprietary data acquisition system (DAS) software to support government and commercial testing. The software is designed for modularity and adaptability to minimize the software development effort for current and future data systems. An additional benefit of the software's architecture is its ability to easily migrate to other testing facilities thus providing future commonality across Stennis. Adapting the software to other Rocket Propulsion Test (RPT) Centers such as MSFC, White Sands, and Plumbrook Station would provide additional commonality and help reduce testing costs for NASA. Ultimately, the software provides the government with unlimited rights and guarantees privacy of data to commercial entities. The project engaged all RPT Centers and NASA's Independent Verification & Validation facility to enhance product quality. The design consists of a translation layer which provides the transparency of the software application layers to underlying hardware regardless of test facility location and a flexible and easily accessible database. This presentation addresses system technical design, issues encountered, and the status of Stennis' development and deployment.

Distributed Acoustic Sensing (DAS) Array near a Highway for Traffic Monitoring and Near-Surface Shear-Wave Velocity Profiles

Science.gov (United States)

2017-12-01

Monitoring traffic is important for many technical reasons. It allows for better design of future roads and assessment of the state of current roads. The number, size, weight, and speed of vehicles control deterioration rate. Also, real-time information supplies data to intelligent information systems to help control traffic. Recently there have been studies looking at monitoring traffic seismically as vibrations from traffic are not sensitive to weather and poor visibility. Furthermore, traffic noise can be used to image S-wave velocity distribution in the near surface by capturing and interpreting Rayleigh and Love waves (Nakata, 2016; Zeng et al. 2016). The capability of DAS for high spatial sampling (1 m), temporal sampling (up to 10 kHz), and distributed nature (tens of kilometers) allows for a closer look at the traffic as it passes and how the speed of the vehicle may change over the length of the array. The potential and difficulties of using DAS for these objectives were studied using two DAS arrays. One at Garner Valley in Southern California (a 700-meter array adjacent to CA Highway 74) and another in Brady Hot Springs, Nevada (an 8700-meter array adjacent to Interstate 80). These studies experimentally evaluated the use of DAS data for monitoring traffic and assessing the use of traffic vibration as non-localized sources for seismic imaging. DAS arrays should also be resilient to issues with lighting conditions that are problematic for video monitoring and it may be sensitive to the weight of a vehicle. This study along a major interstate provides a basis for examining DAS' potential and limitations as a key component of intelligent highway systems.

The data acquisition system PHON for the detectors of the PHOENICS experiment; Das Datenerfassungssystem PHON fuer die Detektoren des PHOENICS-Experiments

Energy Technology Data Exchange (ETDEWEB)

Schneider, W.

1991-07-01

The PHON data acquisition system for the PHOENICS experiment at the stretcher ring ELSA in Bonn and its development is described. PHON is based on a fast parallel CAMAC readout with VME front-end processors and a VAX/VMS computer, allowing c omfortable control and programming. The current configuration of the PHON system at the PHOENICS detector uses two CAMAC branches that are read out in parallel. The data is transferred to the VAX by either the ethernet (max. rate 100 kByte/sec) or a bus coupler device (max. rate 650 kByte/sec). On the VAX the data can be stored on a harddisk and analyzed by several PHON online tasks. The harddisk limits the maximum data rate to a value of approximately 180 kByte/sec. The maximum trigger rate achieved is about 150 Hz. Two kinds of user shells are realized to control the PHON system. A command shell follows the standard of the control language of the VMS operating system and a graphic user interface uses the `X Window System`. The modular structure of the PHON system and the unique kind of creation of all PHON programs makes a further development of the system easy to do. (orig.).

The sick-building syndrome is characterized by the presence of general, non-specific symptoms (e.g., headache, tiredness, respiratory problems, eye trouble, vertigo, nausea, unspecific hypersensitivity) in association with a particular indoor ambience. It is clearly distinguishable from `building-related illness`, referring to a well-defined clinical syndrome due to staying in a building and for which a cause can, in general, be established. Disorders in the case of the sick-building syndrome are manifold and confirmed objectifiable results are hardly available so far. Yet there are some organ-related methods for the confirmation of findings concerning, for instance, the eyes, the skin and the area of the nose. The causes of the incidence of sick-building syndrome are more or less unclear. It is a multifactorial phenomenon involving physical, biological, chemical, individual-specific and psychological factors. Buildings where sick-building syndrome occurs typically exhibit certain properties. The European Community has already made proposals for the investigation of incriminated buildings. A systematic survey by questionnaire together with individual interviews plays an import part towards clarifying the syndrome. (orig./UWA) [Deutsch] Das Sick-Building-Syndrom beschreibt das Vorhandensein von allgemeinen, nicht spezifischen Symptomen (z.B. Kopfschmerzen, Muedigkeit, Atembeschwerden, Augenreizungen, Schwindelgefuehl, Uebelkeit, unspezifische Ueberempfindlichkeit), assoziiert mit einer besonderen Innenraumumgebung. Deutlich hiervon abzugrenzen ist die ``Building related illness``, bei der ein klinisch definiertes Krankheitsbild vorliegt, das durch den Aufenthalt im Gebaeude verursacht wird und fuer das im allgemeinen eine Ursache ermittelt werden kann. Das Beschwerdebild beim Sick-Building-Syndrom ist vielfaeltig, und gesicherte, objektivierbare Befunde liegen hierzu bisher kaum vor. Dennoch gibt es einige organbezogenen Methoden zur Befundabsicherung, z.B. fuer das

System Entropy Measurement of Stochastic Partial Differential Systems

Directory of Open Access Journals (Sweden)

Bor-Sen Chen

2016-03-01

Full Text Available System entropy describes the dispersal of a system’s energy and is an indication of the disorder of a physical system. Several system entropy measurement methods have been developed for dynamic systems. However, most real physical systems are always modeled using stochastic partial differential dynamic equations in the spatio-temporal domain. No efficient method currently exists that can calculate the system entropy of stochastic partial differential systems (SPDSs in consideration of the effects of intrinsic random fluctuation and compartment diffusion. In this study, a novel indirect measurement method is proposed for calculating of system entropy of SPDSs using a Hamilton–Jacobi integral inequality (HJII-constrained optimization method. In other words, we solve a nonlinear HJII-constrained optimization problem for measuring the system entropy of nonlinear stochastic partial differential systems (NSPDSs. To simplify the system entropy measurement of NSPDSs, the global linearization technique and finite difference scheme were employed to approximate the nonlinear stochastic spatial state space system. This allows the nonlinear HJII-constrained optimization problem for the system entropy measurement to be transformed to an equivalent linear matrix inequalities (LMIs-constrained optimization problem, which can be easily solved using the MATLAB LMI-toolbox (MATLAB R2014a, version 8.3. Finally, several examples are presented to illustrate the system entropy measurement of SPDSs.

Fiber-optic distributed acoustic sensing (DAS) uses conventional telecom fibers for a wide variety of monitoring purposes. Fiber-optic arrays can be located along pipelines for leak detection; along borders and perimeters to detect and locate intruders, or along railways and roadways to monitor traffic and identify and manage incidents. DAS can also be used to monitor oil and gas reservoirs and to detect earthquakes. Because thousands of such arrays are deployed worldwide and acquiring data continuously, they can be a valuable source of data for earthquake detection and location, and could potentially provide important information to earthquake early-warning systems. In this presentation, we show that DAS arrays in Mexico and the United States detected the M8.1 and M7.2 Mexico earthquakes in September 2017. At Stanford University, we have deployed a 2.4 km fiber-optic DAS array in a figure-eight pattern, with 600 channels spaced 4 meters apart. Data have been recorded continuously since September 2016. Over 800 earthquakes from across California have been detected and catalogued. Distant teleseismic events have also been recorded, including the two Mexican earthquakes. In Mexico, fiber-optic arrays attached to pipelines also detected these two events. Because of the length of these arrays and their proximity to the event locations, we can not only detect the earthquakes but also make location estimates, potentially in near real time. In this presentation, we review the data recorded for these two events recorded at Stanford and in Mexico. We compare the waveforms recorded by the DAS arrays to those recorded by traditional earthquake sensor networks. Using the wide coverage provided by the pipeline arrays, we estimate the event locations. Such fiber-optic DAS networks can potentially play a role in earthquake early-warning systems, allowing actions to be taken to minimize the impact of an earthquake on critical infrastructure components. While many such fiber

Das Konzept des 'Medialen Habitus'

Directory of Open Access Journals (Sweden)

Sven Kommer

2013-12-01

Full Text Available Sven Kommer fragt in seinem Beitrag, inwieweit das Habitus-Konzept als Erklärungsmuster für die beobachtbare Zementierung sozialer Ungleichheit im Schulsystem greift. Dabei konstatiert der Beitrag, dass alle an der Weiterschreibung des Habitus-Konzepts beteiligten AutorInnen sich darin einig sind, dass es wichtige Beiträge für die Selbst-Aufklärung einer weitestgehend mediatisierten Gesellschaft leistet. Der Artikel geht dabei – auch angesichts der PISA-Studien – von dem empirischen Befund aus, dass die individuelle Ausprägung der Medienkompetenz aufs engste mit den Ressourcen des Elternhauses verbunden ist und sich dabei die elterlichen Formen der Medienerziehung unübersehbar mit den aktuellen medialen Handlungspraxen verbinden. Dieser Befund deckt sich auf weite Strecken auch mit den Ergebnissen der Bildungssoziologie Pierre Bourdieus, weshalb die Diskussionen zum medialen Habitus im Rahmen dieser Ausführungen auch mit empirischen Argumenten unterfüttert werden. Ganz in diesem Sinne arbeitet der Artikel auch heraus, dass die aus dem Kontext der Cultural Studies stammenden Thesen zur Nivellierung kultureller Milieu-Unterschiede wenig empirisch fundiert sind. Der Artikel betont dahingehend, dass hier eine unreflektierte Infiltration durch genuin neoliberales Gedankengut vorliegt, da mit ihr auch die Annahme einer "freien Wahl" von Lebensweg, Milieuzugehörigkeit oder Gender verbunden werden kann. Dabei wir auch eingehend der "Clash of Habitus" diskutiert, der zwischen Lehrenden und Lernenden stattfindet und das Augenmerk ein Mal mehr auf die Tatsache lenkt, das unser Bildungssystem auf dieser pädagogisch relevanten Ebene durch soziale Ungleichheiten gekennzeichnet ist. In his essay, Sven Kommer questions whether the notion of habitus is suitable to support the understanding of the obvious consolidation of inequality in the school system. He shows that all authors active in the continued use of the notion of habitus agree that it

The PoroTomo research team deployed 8700-meters of Distributed Acoustic Sensing (DAS) cable in a shallow trench and 400-meters in a borehole at Brady Hot Springs, Nevada in March 2016 together with an array of 246, three-component geophones. The seismic sensors occupied a natural laboratory 1500 x 500 x 400 meters overlying the Brady geothermal field. The DAS cable was laid out in three parallel zig-zag lines with line segments approximately 100-meters in length and geophones were spaced at approximately 50-m intervals. In several line segments, geophones were co-located within one meter of the DAS cable. Both DAS and the conventional geophones recorded continuously over 15 days. A large Vibroseis truck (T-Rex) provided the seismic source at approximately 250 locations outside and within the array. The Vibroseis protocol called for excitation in one vertical and two orthogonal horizontal directions at each location. For each mode, three, 5-to-80-Hz upsweeps were made over 20 seconds. In addition, a moderate-sized earthquake with a local magnitude of 4.3 was recorded on March 21, 2016. Its epicenter was approximately 150-km away. Several DAS line segments with co-located geophone stations were used to test relationships between the strain rate recorded by DAS and ground velocity recorded by the geophones.

We describe a low noise measuring system based on interdigitated electrodes for sensing bioelectrical signals. The system registers differential voltage measurements in order of microvolts. The base noise during measurements was in nanovolts and thus, the sensing signals presented a very good signal to noise ratio. An excitation voltage of 1Vrms with 10 KHz frequency was applied to an interdigitated capacitive sensor without a material under test and to a mirror device simultaneously. The output signals of both devices was then subtracted in order to obtain an initial reference value near cero volts and reduce parasitic capacitances due to the electronics, wiring and system hardware as well. The response of the measuring system was characterized by monitoring temporal bioelectrical signals in real time of biological materials such as embryo chicken heart cells and bovine suprarenal gland cells.

Kirchner, Stefan

Im Jahre 1953 wurde von James Watson und Francis Crick erstmalig der strukturelle Aufbau der sogenannten DNA (Desoxyribonukleinsäure) beschrieben, welche das Erbgut jedes Lebewesens enthält. Der wesentliche Teil des Erbguts wird dabei durch eine sehr lange Folge der vier Basen Adenin (A), Cytosin (C), Guanin (G) und Thymin (T) codiert. Seit einigen Jahren ist es möglich, die Folge der vier Basen zu einer gegebenen DNA zu bestimmen. Biologen bezeichnen diesen Vorgang als Sequenzierung.

2008-01-01

For carrying out the experiments on nuclear fusion devices in the Institute of Nuclear Fusion, Moscow, a system for experimental data acquisition, data handling and remote access (further 'DAS-T10') was developed and has been used in the Institute since the year 2000. The DAS-T10 maintains the whole cycle of experimental data handling: from configuration of data measuring equipment and acquisition of raw data from the fusion device (the Device), to presentation of math-processed data and support of the experiment data archive. The DAS-T10 provides facilities for the researchers to access the data both at early stages of an experiment and well afterwards, locally from within the experiment network and remotely over the Internet.The DAS-T10 is undergoing a modernization since the year 2007. The new version of the DAS-T10 will accommodate to modern data measuring equipment and will implement improved architectural solutions. The innovations will allow the DAS-T10 to produce and handle larger amounts of experimental data, thus providing the opportunities to intensify and extend the fusion researches. The new features of the DAS-T10 along with the existing design principles are reviewed in this paper

Full Text Available O traçado das estradas que cortam grande número de rios e a drenagem lateral nas estradas faz com que as águas cheguem rapidamente à rede de drenagem aumentando a vazão. Disso resulta grande produção de sedimentos haja vista que algumas estradas e caminhos internos não possuem dissipadores de energia. Portanto o presente trabalho teve por objetivo analisar e discutir o sistema viário das estradas rurais da bacia do Rio das Pedras, Guarapuava-PR e a construção de caixas de contenção como medida preventiva para dissipar energia e conseqüentemente a entrada de sedimentos nos canais fluviais. No estudo utilizou-se de dados cartográficos e de campo para mensurar as estradas rurais e as caixas de contenção. Por meio da análise dos resultados constatou-se que o número de caminhos internos supera as estradas principais, que em grande parte não possui dissipadores de energia, potencializando a entrada de sedimentos nos cursos d‘água. Em dez pontos selecionados aleatoriamente verificou-se 792 cruzamentos de estradas rurais e cursos d’água. Nas estradas rurais com caixas de contenção verificou-se que em torno de 70% destas encontravam-se inativas, havendo uma deterioração em média de 10% do total de caixas de contenção mensuradas a cada dois anos.

To investigate the relationship between function and disease activity in early inflammatory arthritis (EIA). Canadian Early Arthritis Cohort (CATCH) (n=1143) is a multi-site EIA cohort. Correlations between the Health Assessment Questionnaire Disability Index (HAQ) and DAS28 were done at every 3 months for the first year and then at 18 and 24 months. We also investigated the relationship between HAQ and DAS28 by age (<65 versus ≥65) and RF (positive vs negative). Mean HAQ and DAS28 scores were highest at the initial visit with HAQ decreasing over 24 months from a baseline of 0.94 to 0.40 and DAS28 scores decreasing from 4.54 to 2.29. All correlations between HAQ and DAS28 were significant at all time points (p<0.01). The correlations between HAQ and DAS28 were variable over time. The strongest correlation between HAQ and DAS28 occurred at initial visit (most DMARD naive) (n=1,143) and 18 months (r=0.57, n=321) and 24 months (r=0.59, n=214). The baseline correlation between HAQ and DAS28 was significantly different than correlations obtained at 3, 6, and 12 months (p=0.02, 0.01, and 0.01, respectively). Age did not change the association between HAQ and DAS28 {<65 years old (r=0.50, n=868) versus ≥65 (r=0.48, n=254), p=0.49}. The correlation between HAQ and DAS28 was stronger with RF+ patients (r=0.63, n=636) vs RF negative (r=0.47, n=477), p=0.0043. Over 2 years in EIA, HAQ and DAS both improved; correlations at time points were different over 2 years and RF status affected the correlations.

Jaenschwalde coal power plant consists of 3 so-called ``modules`` of 2 power blocks each. The new operation management system at Jaenschwalde power plant has greatly improved the temporal availability and quality of process data needed by its various departments. The possibilities of process data analysis and the various optional extensions are capable of integration in various ways and at reasonable cost. At present the operation management system is managed by two employees. As the job does not even fully occupy these two, they are available for other work as well. In earlier times there were instead 6 process computers whose operation and maintenance occupied 30 employees. Beside these tremendous savings in labour the system has also brought about great functional improvements in terms of the supply of process data for the power plant as a whole and also for the entire VEAG network. [Deutsch] Das Braunkohlekraftwerk Jaenschwalde besteht aus insgesamt 6 Kraftwerksbloecken, von denen jeweils 2 Kraftwerksbloecke sogenannte `Module` bilden. Die zeitliche Verfuegbarkeit und die Guete der von den Fachabteilungen benoetigten Prozessdaten ist durch das neue Betriebsmanagementsystem im Kraftwerk Jaenschwalde drastisch erhoeht worden. Die Moeglichkeiten der Prozessdatenanalyse und die individuellen Erweiterungen sind vielseitig und mit einem ueberschaubaren Aufwand integrierbar. Die Pflege des gesamten heutigen Betriebsmanagementsystems wird heute von 2 Personen durchgefuehrt, die nicht einmal 100% ihrer Arbeitszeit dafuer aufzuwenden haben, so dass sie noch Aufgaben aus anderen Bereichen erledigen koennen. Frueher wurden dagegen 30 Personen fuer die Pflege und Wartung der 6 Prozessrechner benoetigt. Neben dem Einsparungspotential wurde eine grosse funktionelle Verbesserung fuer die Bereitstellung der Prozessdaten im gesamten Kraftwerk und darueber hinaus im gesamten VEAG-Netzwerk erreicht.

All cooling tower construction built so far can be assigned fluidically to the cross-flow or counterflow principle. The new Matrix-Multiflow System, which was developed in cell-construction with ducted aeration for large cooling capacities of the industry and energy economy, corresponds basically to none of the two principles, even if constructively it represents a modified cross-flow tower with cross-flow film internals.

Full Text Available A literatura sobre economia regional, historicamente, conferiu pouco destaque à moeda e à sua capacidade de afetar a economia. Dentre as razões, pode-se apontar a postura ortodoxa assumida pelos economistas regionais como uma das principais. Se a moeda não impacta a economia real no âmbito nacional, certamente não irá desempenhar papel no contexto regional. A despeito da tendência de negligenciar a importância das variáveis monetárias no crescimento das regiões, alguns estudos sobre desenvolvimento regional vêm mostrando que a moeda não é neutra e produz impacto diferenciado no espaço. Entretanto, ainda que tais estudos tenham contribuído para o avanço na discussão regional, não foi elaborado um aparato conceitual que revele como a moeda influencia na decisão locacional das empresas. Este indagação servirá de eixo para o desenvolvimento das reflexões apresentadas no artigo.

Revision of an automated microseismic location algorithm for DAS - 3C geophone hybrid array

Science.gov (United States)

Mizuno, T.; LeCalvez, J.; Raymer, D.

2017-12-01

Application of distributed acoustic sensing (DAS) has been studied in several areas in seismology. One of the areas is microseismic reservoir monitoring (e.g., Molteni et al., 2017, First Break). Considering the present limitations of DAS, which include relatively low signal-to-noise ratio (SNR) and no 3C polarization measurements, a DAS - 3C geophone hybrid array is a practical option when using a single monitoring well. Considering the large volume of data from distributed sensing, microseismic event detection and location using a source scanning type algorithm is a reasonable choice, especially for real-time monitoring. The algorithm must handle both strain rate along the borehole axis for DAS and particle velocity for 3C geophones. Only a small quantity of large SNR events will be detected throughout a large aperture encompassing the hybrid array; therefore, the aperture is to be optimized dynamically to eliminate noisy channels for a majority of events. For such hybrid array, coalescence microseismic mapping (CMM) (Drew et al., 2005, SPE) was revised. CMM forms a likelihood function of location of event and its origin time. At each receiver, a time function of event arrival likelihood is inferred using an SNR function, and it is migrated to time and space to determine hypocenter and origin time likelihood. This algorithm was revised to dynamically optimize such a hybrid array by identifying receivers where a microseismic signal is possibly detected and using only those receivers to compute the likelihood function. Currently, peak SNR is used to select receivers. To prevent false results due to small aperture, a minimum aperture threshold is employed. The algorithm refines location likelihood using 3C geophone polarization. We tested this algorithm using a ray-based synthetic dataset. Leaney (2014, PhD thesis, UBC) is used to compute particle velocity at receivers. Strain rate along the borehole axis is computed from particle velocity as DAS microseismic

Full Text Available Esta síntese do conceito de orogenias abrange desde a Tectônica de Placas dos anos 1970, adendos e modelos "alternativos", que buscam explicar orogenias distantes das zonas de interação de placas. A análise crítica dos modelos originais resultou em adendos que incluem domínios proterozoicos e paleozoicos e observações sobre reologia e história termo-tectônica da litosfera. Os modelos alternativos explicam a orogênese por subdução local de litosfera continental, sem envolver litosfera oceânica. Nos anos 1990, houve notável avanço no estudo das causas da subsidência (tectônica formadora de bacias e estudos que contestam a rigidez das placas e propõem modelos de enfraquecimento devido à ação termal. Orogenias intracontinentais, entendidas como caso extremo da inversão de bacias, ocorrem em praticamente todos os continentes. Esforços gerados em zonas de interação de placas podem ser transmitidas continente adentro por milhares de quilômetros e gerar tectônica deformadora longe de suturas. Embora esteja ainda em estágio de fluxo, o conceito de orogenias intracontinentais ("telessuturais" vem se consolidando, embora não tenha sido incorporado a livros-texto. O histórico e o reexame do tema possibilitam classificar os orógenos segundo três variáveis principais: posição em relação às zonas de sutura, organização geométrico-geológica (em planta e nível de exumação.

  Analisa-se a participação das universidades estaduais no ensino superior do Brasil, comparando-as com as federais, municipais e privadas em termos do número de instituições, vagas, ingressantes, matrículas e concluintes antes e depois da Lei de Diretrizes e Bases da Educação Nacional. Pergunta-se: qual a contribuição para o ensino superior brasileiro e que efeitos as inovações da LDB provocaram no setor? Deseja-se dimensionar essa participação, comparando a parcela de contribuição das UEs com a dos demais segmentos antes das inovações da lei geral. Tomam-se por base os Censos do Ensino Superior realizados pelo INEP, analisando a proporção do segmento em relação ao total. Constatou-se que as estaduais são as primeiras instituições universitárias e que, salvo nas primeiras décadas, quando a federalização subtraiu algumas unidades, até 1996, ampliava sua participação com 20% das instituições, 15% dos ingressantes, 17% das matrículas, 19% de concluintes e  13% das vagas. Desde então, apesar dos acréscimos, tem reduzido sua fatia, tendo, em 2013, 19% das universidades, 5% das vagas, 8% dos ingressantes, 13% das matrículas e 14% dos concluintes, não acompanhando o crescimento das federais e, principalmente, das privadas que, favorecidas com as alterações na legislação, tornaram-se o maior segmento. Conclui-se, então, que a participação das universidades estaduais no ensino superior brasileiro tem experimentado ora ampliação, ora redução, mas sempre favorecendo o acesso ao ensino superior de grandes camadas da população brasileira.   Palavras-chave: Ensino superior.

Im Oktober 2013 setzte der Nobelpreis für Peter Higgs und François Englert den vorläufigen Höhepunkt in der verrückten Geschichte um das sogenannte Gottesteilchen, das Higgs-Boson. Schon im Juli des Vorjahres hatten die Physiker weltweit gejubelt: Mehr als fünfzig Jahre nachdem Peter Higgs und andere Wissenschaftler die Existenz des Teilchens theoretisch begründet hatten, war es im gigantischen Teilchenbeschleuniger CERN gefunden worden. Jetzt erzählen Harald Lesch und seine Co-Autoren, warum sich rund um das Higgs-Teilchen so viele skurrile Missverständnisse und mediale Sensationen ranken. Gewohnt kurzweilig und gut verständlich enthüllen sie, wie aus dem verzweifelt gesuchten „gottverdammten Teilchen“ das Gottesteilchen wurde, dass der Urknall nicht simuliert werden kann und dass Schwarze Löcher nicht unbedingt alles verschlingende Monster sind.

Absolute calibration in vivo measurement systems

International Nuclear Information System (INIS)

Kruchten, D.A.; Hickman, D.P.

1991-02-01

Lawrence Livermore National Laboratory (LLNL) is currently investigating a new method for obtaining absolute calibration factors for radiation measurement systems used to measure internally deposited radionuclides in vivo. Absolute calibration of in vivo measurement systems will eliminate the need to generate a series of human surrogate structures (i.e., phantoms) for calibrating in vivo measurement systems. The absolute calibration of in vivo measurement systems utilizes magnetic resonance imaging (MRI) to define physiological structure, size, and composition. The MRI image provides a digitized representation of the physiological structure, which allows for any mathematical distribution of radionuclides within the body. Using Monte Carlo transport codes, the emission spectrum from the body is predicted. The in vivo measurement equipment is calibrated using the Monte Carlo code and adjusting for the intrinsic properties of the detection system. The calibration factors are verified using measurements of existing phantoms and previously obtained measurements of human volunteers. 8 refs

Entropy Measurement for Biometric Verification Systems.

Science.gov (United States)

Lim, Meng-Hui; Yuen, Pong C

2016-05-01

Biometric verification systems are designed to accept multiple similar biometric measurements per user due to inherent intrauser variations in the biometric data. This is important to preserve reasonable acceptance rate of genuine queries and the overall feasibility of the recognition system. However, such acceptance of multiple similar measurements decreases the imposter's difficulty of obtaining a system-acceptable measurement, thus resulting in a degraded security level. This deteriorated security needs to be measurable to provide truthful security assurance to the users. Entropy is a standard measure of security. However, the entropy formula is applicable only when there is a single acceptable possibility. In this paper, we develop an entropy-measuring model for biometric systems that accepts multiple similar measurements per user. Based on the idea of guessing entropy, the proposed model quantifies biometric system security in terms of adversarial guessing effort for two practical attacks. Excellent agreement between analytic and experimental simulation-based measurement results on a synthetic and a benchmark face dataset justify the correctness of our model and thus the feasibility of the proposed entropy-measuring approach.

A shielded measurement system for irradiated nuclear fuel measurements

1999-01-01

The US Department of Energy (DOE) is driving a transition toward dry storage of irradiated nuclear fuel (INF), toward characterization of INF for final disposition, and toward resumption of measurement-based material control and accountability (MC and A) efforts for INF. For these reasons, the ability to efficiently acquire radiological measurements of INF in a dry environment is important. The DOE has recently developed a guidance document proposing MC and A requirements for INF. The intent of this document is to encourage the direct measurement of INF on inventory within DOE. The guidance document reinforces and clarifies existing material safeguards requirements as they pertain to INF. Validation of nuclear material contents of non-self-protecting INF must be accomplished by direct measurement, application of validated burnup codes using qualified initial fissile content, burnup data, and age or by other valid means. The fuel units must remain intact with readable identification numbers. INF may be subject to periodic inventories with visual item accountability checks. Quantitative measurements may provide greater assurance of the integrity of INF inventories at a lower cost and with less personnel exposure than visual item accountability checks. Currently, several different approaches are used to measure the radiological attributes of INF. Although these systems are useful for a wide variety of applications, there is currently no relatively inexpensive measurement system that is readily deployable for INF measurements for materials located in dry storage. The authors present the conceptual design of a shielded measurement system (SMS) that could be used for this purpose. The SMS consists of a shielded enclosure designed to house a collection of measurement systems to allow measurements on spent fuel outside of a hot cell. The phase 1 SMS will contain 3 He detectors and ionization chambers to allow for gross neutron and gamma-ray measurements. The phase 2 SMS

At the beginning of the project there was considerable uncertainty as to the influence of clouds of all kinds on the energy budget of the atmosphere, the quantities and impact of aerosols, and, especially, the physics of high curl clouds. There was neither a possibility to model such cloud systems, nor did reliable measuring methods exist. This interconnected project contributed to the solution of these problems with the aim to create a solid basis of work for future climate researches. Simultaneously, measurements were carried out, satellite data analysed, aerosol data by different authors compiled and evaluated, and numerical simulations of cloud sheets carried out. (orig.) [Deutsch] Zu Beginn des Vorhabens herrschten erhebliche Unsicherheiten ueber den Einfluss von Wolken aller Arten auf den Energiehaushalt der Atmosphaere, ueber die Mengen und Wirkungen des Aerosols - und insbesondere ueber die Physik der hohen Cirren.

Das Verbundvorhaben sollte zur Loesung dieser Probleme beitragen mit dem Ziel, eine solide Arbeitsbasis fuer zukuenftige Aufgaben der Klimaforschung zu schaffen. Es wurden gleichzeitig Messungen durchgefuehrt, Satellitendaten analysiert, Aerosoldaten unterschiedlicher Autoren zusammengetragen und geprueft sowie numerische Simulationen von Wolkenfeldern durchgefuehrt.

Ga-67 DFO-DAS-fibrinogen scanning was performed in 15 patients to detect fresh arterial thrombus. Seven patients were preoperative cases of aortic aneurysm and eight were postoperative cases of graft bypass. Scanning was performed on the first and second days after the injection. Nine of 13 grafts in eight cases were visualized by 67 Ga-DFO-DAS-fibrinogen scan. Velour Dacron grafts were more strongly visualized compared with woven Dacron or Goatex. In three patients with aortic aneurysm in whom fresh thrombus was identified by operative findings, arterial thrombus was clearly visualized by 67 Ga-DFO-DAS-fibrinogen scan, whereas in three other patients with aortic aneurysm, thrombus was not visualized, although it was identified by other examinations. In one case, a marked accumulation was observed in the abdominal aorta, although no arterial thrombus was found at operation. This was thought to be an accumulation in a blood pool because it decreased on the second day. We think it important to observe the relative changes of accumulation. (author)

Freeman, H.D.

1981-10-01

The Pacific Northwest Laboratory (PNL) is developing cover technology for uranium mill tailings that will inhibit the diffusion of radon to the atmosphere. As part of this cover program, an improved radon flux measurement system has been developed. The radon measurement system is a recirculating, pressure-balanced, flow-through system that uses activated carbon at ambient temperatures to collect the radon. With the system, an area of 0.93 m 2 is sampled for periods ranging from 1 to 12 h. The activated carbon is removed from the radon trap and the collected radon is determined by counting the 214 Bi daughter product. Development of the system included studies to determine the efficiency of activated carbon, relative calibration measurements and field measurements made during 1980 at the inactive tailings pile in Grand Junction, Colorado. Results of these studies are presented

It is important to understand the atmospheric aerosols compositions and size distributions since they greatly affect the environment and human health. Particles in the convection layer have been a great concern in global climate changes. To understand these characteristics satellite, aircraft, and radio sonde measurement methods have usually been used. An aircraft aerosol sampling using a filter and/or impactor was the method commonly used (Jay, 2003). However, the flight speed particle sampling had some technical limitations (Hermann, 2001). Moreover, the flight legal limit, altitude, prohibited airspace, flight time, and cost was another demerit. To overcome some of these restrictions, Tethered Balloon Package System (T.B.P.S.) and Recoverable Sonde System(R.S.S.) were developed with a very light optical particle counter (OPC), impactor, and condensation particle counter (CPC). Not only does it collect and measure atmospheric aerosols depending on altitudes, but it also monitors the atmospheric conditions, temperature, humidity, wind velocity, pressure, GPS data, during the measurement (Eun, 2013). In this research, atmospheric aerosol measurement using T.B.P.S. in Ansan area is performed and the measurement results will be presented. The system can also be mounted to an unmanned aerial vehicle (UAV) and create an aerial particle concentration map. Finally, we will present measurement data using Tethered Balloon Package System (T.B.P.S.) and R.S.S (Recoverable Sonde System).

Full Text Available http://dx.doi.org/10.5007/1677-2954.2012v11nesp1p1   Schopenhauer gilt als Vorreiter oder erster Vertreter der Lebensphilosophie, wie sie später von Dilthey, Nietzsche, Bergson und anderen entfaltet wurde. Im Unterschied zur klassischen Lebensphilosophie und zu den an sie anknüpfenden ethischen Entwürfen wird das Leben bei Schopenhauer aber nicht als Zweck betrachtet, sondern als Mittel zu einem anderen Zweck, nämlich für die Ethik, die in der Verneinung des Willens zum Leben gipfelt. Schon in den frühesten handschriftlichen Aufzeichnungen verwendet Schopenhauer verschiedene Metaphern, um das Leben als Medium der ethischen Erkenntnis zu charakterisieren. Besonders häufig tritt dabei das Bild vom Leben als Spiegel auf, in dem der Mensch sein eigenes Wesen und damit auch das Wesen der Welt erblickt. Im Hauptwerk wird dann dieses Bild vom Begriff der Objektivation des Willens abgelöst. Insofern die höchste und deutlichste Objektivation des Willens der Lebenslauf des menschlichen Individuums darstellt, ist Schopenhauers Lebensbegriff eng mit seiner Charakterlehre verknüpft. In dem Beitrag wird das verwickelte Verhältnis von Leben, Erkennen und Ethik vor dem Hintergrund der proto-hermeneutischen Metaphysikkonzeption Schopenhauers anhand der Entwicklung der Spiegelmetapher betrachtet.

Mani, V.V.S.

1985-01-01

The dependence of a bulk facility handling Purex Process on the control measurement system for evaluating the process performance needs hardly be emphasized. process control, Plant control, inventory control and quality control are the four components of the control measurement system. The scope and requirements of each component are different and the measurement methods are selected accordingly. However, each measurement system has six important elements. These are described in detail. The quality assurance programme carried out by the laboratory as a mechanism through which the quality of measurements is regularly tested and stated in quantitative terms is also explained in terms of internal and external quality assurance, with examples. Suggestions for making the control measurement system more responsive to the operational needs in future are also briefly discussed. (author)

Computerized system for measuring cerebral metabolism

McGlone, J.S.; Hibbard, L.S.; Hawkins, R.A.; Kasturi, R.

1987-01-01

A computerized stereotactic measurement system for evaluating rat brain metabolism was developed to utilize the large amount of data generated by quantitative autoradiography. Conventional methods of measurement only analyze a small percent of these data because these methods are limited by instrument design and the subjectiveness of the investigator. However, a computerized system allows digital images to be analyzed by placing data at their appropriate three-dimensional stereotactic coordinates. The system automatically registers experimental data to a standard three-dimensional image using alignment, scaling, and matching operations. Metabolic activity in different neuronal structures is then measured by generating digital masks and superimposing them on to experimental data. Several experimental data sets were evaluated and it was noticed that the structures measured by the computerized system, had in general, lower metabolic activity than manual measurements had indicated. This was expected because the computerized system measured the structure over its volume while the manual readings were taken from the most active metabolic area of a particular structure

A prototype switched Ethernet data acquisition system has been built up and successfully operated in HL-1M tokamak experiments. The system is based on a switched high bandwidth Ethernet network with which the CAMAC crates are directly interfaced. It takes the advanced features of LAN switch and Ethernet CAMAC controller (ECC 1365 MK III, HYTEC product) to avoid the rewriting of CAMAC driver for an individual computer system and to ensure high data transmission rate between CAMAC system and host computers on the network. It is a new approach to DAS system architecture and provides a solution for a well-known bottleneck problem in traditional distributed DAS system for fusion research. An average throughput of the test system reaches over 100 Mbps. The system features also an easy and low cost migration from traditional distributed DAS system. In the paper, the hardware configuration, software structure, performance of the system and the method of migrating from current DAS system are discussed in detail. (orig.)

Comparison of Disease Activity Score in 28 joints with ESR (DAS28), Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire Disability Index (HAQ-DI) & Routine Assessment of Patient Index Data with 3 measures (RAPID3) for assessing disease activity in patients with rheumatoid arthritis at initial presentation.

In patients with rheumatoid arthritis (RA), disease severity assessment is done using Disease Activity Score in 28 joints with ESR (DAS28). Computing DAS28 is time-consuming, requires laboratory testing and an online calculator. There is a need to validate rapid methods of disease severity assessment for routine daily use. This study was conducted to compare DAS28, Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire Disability Index (HAQ-DI) and Routine Assessment of Patient Index Data with 3 measures (RAPID3) to assess the disease activity in patients with RA. We prospectively studied the utility of CDAI, HAQ-DI and RAPID3 scoring in 100 consecutive newly diagnosed, disease modifying antirheumatic drugs (DMARDs) naïve adult patients with RA seen during January 2013 and June 2014 at a tertiary care teaching hospital in south India. The mean age of the patients was 42.1±11.6 yr, there were 82 females. The median [interquartile range (IQR)] symptom duration was 6 (range 4-12) months. The median (IQR) DAS28, CDAI, HAQ-DI and RAPID3 scores at presentation were 7 (6-7), 36 (28-43), 2 (1-2) and 17 (13-19), respectively. A significant positive correlation was observed between DAS28 and CDAI (r=0.568; Pfair' agreement was observed in between DAS28 and CDAI (kappa-statistic=0.296). The agreement between DAS28 and HAQ-DI (kappa-statistic=0.007) and RAPID3 (kappa-statistic=0.072) was less robust. In adult patients with RA, in the setting where illiteracy is high, CDAI emerged as the preferred choice for rapid assessment of severity of disease at the time of initial presentation.

Measuring Systemic Risk

DEFF Research Database (Denmark)

Acharya, Viral V.; Heje Pedersen, Lasse; Philippon, Thomas

We present a simple model of systemic risk and we show that each financial institution's contribution to systemic risk can be measured as its systemic expected shortfall (SES), i.e., its propensity to be undercapitalized when the system as a whole is undercapitalized. SES increases...... with the institution's leverage and with its expected loss in the tail of the system's loss distribution. Institutions internalize their externality if they are ‘taxed’ based on their SES. We demonstrate empirically the ability of SES to predict emerging risks during the financial crisis of 2007-2009, in particular......, (i) the outcome of stress tests performed by regulators; (ii) the decline in equity valuations of large financial firms in the crisis; and, (iii) the widening of their credit default swap spreads....

Full Text Available O presente artigo está ancorado na Neurolinguística de orientação enunciativo-discursiva. A demanda por uma proposta de classificação gradual (em oposição à tradicional classificação categorial das preposições surgiu quando nos propusemos a tarefa de descrever o funcionamento das preposições na fala de sujeitos que apresentam uma linguagem heterogênea. Nestes casos, as classificações correntes das preposições não se mostraram satisfatórias. Os motivos pelos quais preferimos uma classificação que dispõe as preposições numa escala de acordo com os seus graus de gramaticalização serão dispostos depois de feita uma revisão da literatura sobre as classificações das preposições. As classificações propostas por diferentes gramáticos são analisadas juntamente com aquelas adotadas por linguistas preocupados em descrever a linguagem agramática de sujeitos com afasia de produção.

Renata Frasson de Azevedo

2003-10-01

Full Text Available A latência do produto de distorção das emissões otoacústicas é definido como o tempo que o estimulo acústico leva para alcançar o local gerador da emissão otoacústica na cóclea e retornar ao meato acústico externo, no local do registro. A latência das emissões otoacústicas pode ser um instrumento útil para analisar mudanças na maturação coclear assim como os micromecanismos cocleares, já que há uma relação entre a latência das emissões otoacústicas produto de distorção EOAPD e a onda viajante coclear. Estudos em adultos mostram uma diminuição da latência com o aumento da freqüência sonora, variando de 13.8 ms em 787 Hz a 4.4 ms em 5 Hz. Esta diminuição ocorre devido à organização tonotópica da cóclea. São escassos os trabalhos nesta área e não são encontrados critérios de normalidade para estas medidas, principalmente em recém-nascidos. OBJETIVO: Sendo assim, o objetivo deste trabalho foi caracterizar as medidas da latência das EOAPD em neonatos nascidos a termo e não pertencentes ao grupo de risco para perda auditiva. FORMA DE ESTUDO: Caso controle. MATERIAL E MÉTODO: Foram avaliados 31 neonatos, de ambos os sexos e nascidos a termo, sem intercorrências. O procedimento utilizado foi o programa Latencygram. As freqüências testadas foram de 3 a 6 KHz na intensidade de 70 dBNA para f1 e f2. RESULTADO: Os resultados obtidos mostraram uma diminuição da latência com o aumento da freqüência sonora e uma diferença entre os sexos.Latency of distortion product otoacoustic emissions (DPOE is defined as the time that the acoustic stimulus takes to reach the site generating the otoacoustic emission, inside de cochlea, and the return to the external acoustic meatus, to be register.

Full Text Available An embedded time interval data acquisition system (DAS is developed for zero power reactor (ZPR noise experiments. The system is capable of measuring the correlation or probability distribution of a random process. The design is totally implemented on a single Field Programmable Gate Array (FPGA. The architecture is tested on different FPGA platforms with different speed grades and hardware resources. Generic experimental values for time resolution and inter-event dead time of the system are 2.22 ns and 6.67 ns respectively. The DAS can record around 48-bit x 790 kS/s utilizing its built-in fast memory. The system can measure very long time intervals due to its 48-bit timing structure design. As the architecture can work on a typical FPGA, this is a low cost experimental tool and needs little time to be established. In addition, revisions are easily possible through its reprogramming capability. The performance of the system is checked and verified experimentally.

Neste artigo, são apresentadas as principais técnicas de determinação de tamanho de partículas e os potenciais benefícios de sua utilização em pesquisas e no aperfeiçoamento de projetos e rotinas de operação de sistemas de tratamento de água e esgoto sanitário.The improvement of water and wastewater treatment systems has been limited by the little knowledge of phenomena that take place inside the units and by the use of non-specific parameters (e.g. BOD, COD etc. in monitoring and controlling of treatment processes and operations. On the other hand, phenomena such as mass transfer, adsorption, diffusion and biochemical reaction are all influenced by particle size distribution, in a way that the use of particle size measurement can aid in choosing and improving treatment technology and in adoption of appropriate operational procedures. In this article, the main particle size measurement techniques are presented, as well as the potential benefits of its use in research and in the improvement of design and operational routines for water and wastewater treatment systems.

Foster, L.A.; Wachter, J.R.; Hagan, R.C.

1995-03-01

The Multiple Assay Dual Analysis Measurement (MADAM) system is a combined low-level and transuranic waste assay system. The system integrates commercially available Segmented Gamma Scanner (SGS) capability with a multienergy x-ray and gamma-ray analysis to measure these two waste forms. In addition, the system incorporates a small neutron slab detector to satisfy safeguards concerns and the capability for automated high-resolution gamma-ray analysis for isotope identification. Since delivery of the system to this facility, an evaluation of the waste measurement characteristics of the system has been conducted. A set of specially constructed NIST-traceable standards was fabricated for calibration and evaluation of the low-level waste (LLW) measurement system. The measurement characteristics of the LLW assay system were determined during the evaluation, including detection limits for all isotopes of interest, matrix attenuation effects, and detector response as a function of source position. Based on these studies, several modifications to the existing analysis algorithms have been performed, new correction factors for matrix attenuation have been devised, and measurement error estimates have been calculated and incorporated into the software.

Loss less real-time data compression based on LZO for steady-state Tokamak DAS

International Nuclear Information System (INIS)

Pujara, H.D.; Sharma, Manika

2008-01-01

The evolution of data acquisition system (DAS) for steady-state operation of Tokamak has been technology driven. Steady-state Tokamak demands a data acquisition system which is capable enough to acquire data losslessly from diagnostics. The needs of loss less continuous acquisition have a significant effect on data storage and takes up a greater portion of any data acquisition systems. Another basic need of steady state of nature of operation demands online viewing of data which loads the LAN significantly. So there is strong demand for something that would control the expansion of both these portion by a way of employing compression technique in real time. This paper presents a data acquisition systems employing real-time data compression technique based on LZO. It is a data compression library which is suitable for data compression and decompression in real time. The algorithm used favours speed over compression ratio. The system has been rigged up based on PXI bus and dual buffer mode architecture is implemented for loss less acquisition. The acquired buffer is compressed in real time and streamed to network and hard disk for storage. Observed performance of measure on various data type like binary, integer float, types of different type of wave form as well as compression timing overheads has been presented in the paper. Various software modules for real-time acquiring, online viewing of data on network nodes have been developed in LabWindows/CVI based on client server architecture

Magnetic-Field-Response Measurement-Acquisition System

Woodward, Stanley E.; Shams, Qamar A.; Fox, Robert L.; Taylor, Bryant D.

2006-01-01

A measurement-acquisition system uses magnetic fields to power sensors and to acquire measurements from sensors. The system alleviates many shortcomings of traditional measurement-acquisition systems, which include a finite number of measurement channels, weight penalty associated with wires, use limited to a single type of measurement, wire degradation due to wear or chemical decay, and the logistics needed to add new sensors. Eliminating wiring for acquiring measurements can alleviate potential hazards associated with wires, such as damaged wires becoming ignition sources due to arcing. The sensors are designed as electrically passive inductive-capacitive or passive inductive-capacitive-resistive circuits that produce magnetic-field-responses. One or more electrical parameters (inductance, capacitance, and resistance) of each sensor can be variable and corresponds to a measured physical state of interest. The magnetic-field- response attributes (frequency, amplitude, and bandwidth) of the inductor correspond to the states of physical properties for which each sensor measures. For each sensor, the measurement-acquisition system produces a series of increasing magnetic-field harmonics within a frequency range dedicated to that sensor. For each harmonic, an antenna electrically coupled to an oscillating current (the frequency of which is that of the harmonic) produces an oscillating magnetic field. Faraday induction via the harmonic magnetic fields produces an electromotive force and therefore a current in the sensor. Once electrically active, the sensor produces its own harmonic magnetic field as the inductor stores and releases magnetic energy. The antenna of the measurement- acquisition system is switched from a transmitting to a receiving mode to acquire the magnetic-field response of the sensor. The rectified amplitude of the received response is compared to previous responses to prior transmitted harmonics, to ascertain if the measurement system has detected a

Thrombus scintigraphy with Ga-67 DFO-DAS-Fibrinogen, 2

In our previous in vivo study 67 Ga DFO-DAS-Fibrinogen was assessed for its usefulness as a radiopharmaceutical for the detection of thrombin in experimental animals (Report 1). The present study was undertaken to appraise the diagnostic value of 67 Ga DFO-DAS-Fibrinogen in human disease, especially in relation to blood coagulability as well as to thrombolytic drug regimen being given, in an effort to investigate its clinical applicability. Involved in this study were 48 patients with thrombosis proven by X-ray CT and other examinations. Of these 48, 42 had arterial thrombosis (20 with aortic aneurysm including the dissecting form, 11 in postoperative condition following vascular surgery with a prosthesis, 9 with intracardiac thrombosis accompanying heart disease, and 1 each with occlusive arteriosclerosis and cerebral infarction) and 6 had venous thrombosis. The 67 Ga DFO-DAS-Fibrinogen test proved to be positive in 55 % of arterial thrombin and in 50 % of venous thrombin. It is interesting to note that as high a positivity rate as 80 % was obtained for aortic aneurysm, although the positivity rate was disappointingly low for left atrial thrombin. No distinct correlation was noted to exist between the degree of accumulation of the tracer in thrombotic lesions and any of factors conceivably of clinical releavance, i.e. time elapsing from onset till testing, thrombolytic medication being given, and hematological factors. 67 Ga DFO-DAS-Fibrinogen appeared to be a radiodiagnostic agent that could possibly indicate the existing activity status of thrombosis.

Full Text Available Das polyzystische Ovarialsyndrom (PCOS ist eine komplexe Erkrankung und betrifft mindestens 5–10 % aller Frauen. Es ist charakterisiert durch Hyperandrogenismus (klinisch und/oder biochemisch, Oligo- oder Anovulation und polyzystische Ovarien. In der Pathogenese spielt neben der Hyperandrogenämie und der abnormen Gonadotropinsekretion die Insulinresistenz eine zentrale Rolle. Ein genetischer Hintergrund des PCOS wird vermutet, neben verschiedenen Kandidatengenen werden auch genomweite Assoziationsstudien neue Kenntnisse bringen, um in Zukunft sowohl Diagnose als auch Therapie des PCOS zu vereinfachen. Das PCOS bringt ein hohes metabolisches Risiko mit sich, ca. die Hälfte aller betroffenen Frauen ist adipös, viele leiden an Insulinresistenz, Glukosetoleranzstörungen und Diabetes mellitus Typ 2. Weiters sind viele Frauen mit PCOS von unerfülltem Kinderwunsch, Hirsutismus, Akne und androgenetischer Alopezie betroffen. Vor allem Adipositas und Hirsutismus führen zu einer starken psychischen Belastung betroffener Frauen, das Suizidrisiko ist deutlich erhöht. Zur exakten Diagnose des PCOS bedarf es einer genauen Anamnese und körperlichen Untersuchung mit anthropometrischen Messungen und Hirsutismus-Score. Ein Hormonstatus mit Bestimmung von Androgenen ist unerlässlich, ein LHRH-Test kann weitere diagnostische Hinweise liefern. Weiters sollten zur metabolischen Abklärung ein oraler Glukosetoleranztest, eine Messung der Körperfettverteilung und die Bestimmung eines Lipidstatus erfolgen. Therapeutisch ist vor allem bei adipösen Frauen eine Lebensstilintervention am wichtigsten, zusätzlich kommen Insulinsensitizer und orale Kontrazeptiva zum Einsatz. Zusammenfassend ist das PCOS eine extrem häufige Erkrankung mit komplexen Folgen und bedarf einer konsequenten, interdisziplinären individuellen Therapie bei betroffenen Frauen.

SST-1 Data Acquisition Systems have been reliably operated in the SST-1 experimental campaigns. At present different distributed DAS caters the need of around 130 channels from different SST-1 diagnostics and its subsystems. PXI based DAS and CAMAC based DAS have been chosen to cater the need, with sampling rates varying from 10Ksamples/sec to 1Msamples/sec. For these large sets of channels acquiring from individual diagnostics and subsystems has been a combined setup, subjected to a gradual phase of optimization and tests resulting into a series of improvisations over the recent operations.

Measuring the Value of Earth Observation Information with the Gravity Research and Climate Experiment (GRACE) Satellite

Determining how much to invest in earth observation technology depends in part on the value of information (VOI) that can be derived from the observations. We design a framework and then evaluate the value-in-use of the NASA Gravity Research and Climate Experiment (GRACE) for regional water use and reliability in the presence of drought. As a technology that allows measurement of water storage, the GRACE Data Assimilation System (DAS) provides information that is qualitatively different from that generated by other water data sources. It provides a global, reproducible grid of changes in surface and subsurface water resources on a frequent and regular basis. Major damages from recent events such as the 2012 Midwest drought and the ongoing drought in California motivate the need to understand the VOI from remotely sensed data such as that derived from GRACE DAS. Our conceptual framework models a dynamic risk management problem in agriculture. We base the framework on information from stakeholders and subject experts. The economic case for GRACE DAS involves providing better water availability information. In the model, individuals have a "willingness to pay" (wtp) for GRACE DAS - essentially, wtp is an expression of savings in reduced agricultural input costs and for costs that are influenced by regional policy decisions. Our hypothesis is that improvements in decision making can be achieved with GRACE DAS measurements of water storage relative to data collected from groundwater monitoring wells and soil moisture monitors that would be relied on in the absence of GRACE DAS. The VOI is estimated as a comparison of outcomes. The California wine grape industry has features that allow it to be a good case study and a basis for extrapolation to other economic sectors. We model water use in this sector as a sequential decision highlighting the attributes of GRACE DAS input as information for within-season production decisions as well as for longer-term water reliability.

Measuring Systemic Risk

We present a simple model of systemic risk and we show that each financial institution’s contribution to systemic risk can be measured as its systemic expected shortfall (SES), i.e., its propensity to be undercapitalized when the system as a whole is undercapitalized. SES increases...... with the institution’s leverage and with its expected loss in the tail of the system’s loss distribution. Institutions internalize their externality if they are “taxed” based on their SES. We demonstrate empirically the ability of SES to predict emerging risks during the financial crisis of 2007-2009, in particular......, (i) the outcome of stress tests performed by regulators; (ii) the decline in equity valuations of large financial firms in the crisis; and, (iii) the widening of their credit default swap spreads....

State of Paraná. An ecological study was conducted, in which municipal districts were put together in homogeneous areas, following not only general socio-economic indexes but also women's social participation based on multivariate analysis techniques. Social gender indicators were calculated from Censo/IBGE 2000 (Brazilian Institute of Geography and Statistics and reproductive health (1998-2002 period database, which were built from information from the SUS (Centralized Health System database. The ratio between rates was calculated to measure social gender inequalities and gross average variation in order to measure inequalities in women's reproductive health were calculated among the municipal districts. The results show that there are meaningful differences in women's reproductive health among districts in socio-economic type classification as well as in women's social participation. Socio-economic groups 4 and 5 in general present less favorable indicators of women's reproductive health. These two groups involve 160 districts (40% of the state total and a population of 1.4 million people. These districts are concentrated in 9 of the 22 health units. Gender social differences were noticed with disadvantages to women. The permanent identification of women's reproductive health inequalities in Paraná might be a tool to help in decision-making when working to reverse these inequalities.

The aim of this paper is design and implementation of an up-to-date control room. The previous control room had a lot of constraints and it was not apposite to the sophisticated diagnostic systems as well as to the modern control and multivariable systems. Although it provided the best output for the considered experiments and implementing offline algorithms among all similar plants, it needed to be developed to provide more capability for complex algorithm mechanisms and this work introduces our efforts in this area. Accordingly, four leading systems were designed and implemented, including real-time control system, online Data Acquisition System (DAS), offline DAS, monitoring and data transmission system. In the control system, three real-time control modules were established based on Digital Signal Processor (DSP). Thanks to them, implementation of the classic and linear and nonlinear intelligent controllers was possible to control the plasma position and its elongation. Also, online DAS was constructed in two modules. Using them, voltages and currents of charge for the capacitor banks and pressure of different parts in vacuum vessel were measured and monitored. Likewise, by real-time processing of the online data, the safety protocol of plant performance was accomplished. In addition, the offline DAS was organized in 13 modules based on Field Programmable Gate Array (FPGA). This system can be used for gathering all diagnostic, control, and performance data in 156 channels. Data transmission system and storing mechanism in the server was provided by data transmitting network and MDSplus standard protocol. Moreover, monitoring software was designed so that it could display the required plots for physical analyses. Taking everything into account, this new platform can improve the quality and quantity of research activities in plasma physics for Damavand tokamak.

We conducted experiments in the Underground Education Mining Center on the Montana Tech campus, Butte, Montana, to make a direct comparison between Digital Acoustic Sensing (DAS) and three-component geophones in a mining setting. The sources used for this project where a vertical sledgehammer, oriented shear sledgehammer, and blasting caps set off in both unstemmed and stemmed drillholes. Three-component Geospace 20DM geophones were compared with three different types of fiber-optic cable: (1) Brugg strain, (2) Brugg temperature, and (3) Optical Cable Corporation strain. We attached geophones to the underground mine walls and on the ground surface above the mine. We attached fiber-optic cables to the mine walls and placed fiber-optic cable in boreholes drilled through an underground pillar. In addition, we placed fiber-optic cables in a shallow trench at the surface of the mine. We converted the DAS recordings from strain rate to strain prior to comparison with the geophone data. The setup of the DAS system for this project led to a previously unknown triggering problem that compromised the early samples of the DAS traces often including the first-break times on the DAS records. Geophones clearly recorded the explosives; however, the large amount of energy and its close distance from the fiber-optic cables seemed to compromise the entire fiber loop. The underground hammer sources produced a rough match between the DAS records and the geophone records. However, the sources on the surface of the mine, specifically the sources oriented inline with the fiber-optic cables, produced a close match between the fiber-optic traces and the geophone traces. All three types of fiber-optic cable that were in the mine produced similar results, and one type did not clearly outperform the others. Instead, the coupling of the cable to rock appears to be the most important factor determining DAS data quality. Moreover, we observed the importance of coupling in the boreholes, where

Full Text Available O conflito de interesses entre executivos e proprietários é uma questão amplamente difundida na academia, já documentada em 1932 por Berle e Means, trazendo à tona o clássico conflito de interesses entre agente e principal discutido pela Teoria da Agência. A premissa por trás da governança corporativa é que as pessoas que estão dentro das corporações não necessariamente agem visando o melhor para os provedores de fundos. Partindo deste pressuposto, o trabalho em questão visa verificar a influência dos aspectos de governança corporativa na eficiência das empresas de capital aberto brasileiras. O estudo une técnicas de otimização estática através de Análise Envoltória de Dados (DEA para identificar a eficiência das empresas de capital aberto, com Dados em Painel para identificar a influência da governança corporativa na eficiência das empresas. Os dados foram coletados manualmente dos relatórios 20-F da Security Exchange Commission (SEC das empresas brasileiras que possuem American Depositary Receipts (ADRs, já que a base de dados não está disponível, no Brasil, de uma forma completa. Grande parte das hipóteses foi confirmada, evidenciando as condições particulares das finanças corporativas no Brasil no que tange a Governança Corporativa. A incipiência do mercado de capitais brasileiro é percebida em várias análises, ressaltando que o histórico do sistema corporativo brasileiro é um dos limitantes da eficiência das empresas. As condições que prevalecem são: (i alta sobreposição propriedade-direção; (ii conselhos de administração de baixa efetividade; (iii em grupos familiares, os papéis dos acionistas, dos conselhos e da direção não são bem definidos; (iv existe pouca clareza quanto à relação benefício-custo da boa governança; (v baixa eficácia dos conselhos de administração; e (vi indícios de conflitos de interesses, relativizados por incentivos explícitos e implícitos.

Intestinal metaplasia (IM) is a precursor for malignancies at the esophagogastric junction. A monoclonal antibody, mAbDAS-1, can probably identify cellular characteristics of IM before the appearance of goblet cells. The aim of this study was to examine the prevalence of mAbDAS-1 positivity in biopsies from the squamocolumnar junction (SCJ) and to correlate this positivity with the presence of IM and clinical findings. In 559 patients, reflux symptoms were scored, and the presence of reflux esophagitis and hiatus hernia was evaluated during endoscopy. Two biopsy specimens were obtained from the SCJ. In a subset of patients (n = 99), biopsies from the endoscopically defined cardiac region (2 cm distal to proximal margin of gastric folds) were available. Biopsy specimens were stained with hematoxylin and eosin, Alcian Blue, modified Giemsa, and mAbDAS-1. mAbDAS-1 positivity was observed in the SCJ biopsies of 201 of 486 (41.4%) patients without IM and in 64 of 73 (87.7%) patients with IM. Patients without IM but with antibody positivity showed similar histological characteristics as patients with IM at the SCJ. Biopsies of 123 of 559 patients (22%) revealed a columnar-cuboidal epithelium, which was found to be mAbDAS-1 positive in 64.2% (77 of 123). Tissue specimens from the cardiac region without IM stained positive in 14.2% (13 of 91), 12 of those also stained at the SCJ. In patients without IM, a high prevalence of mAbDAS-1 positivity was observed. Biopsies of these patients showed similar histological characteristics as patients with IM. Although not all patients exhibiting this reactivity may develop IM, mAbDAS-1 reactivity may help in the understanding of the histogenesis of IM at the SCJ.

PSICOGÊNESE E HISTÓRIA DAS CIÊNCIAS: ELEMENTOS PARA UMA EPISTEMOLOGIA CONSTRUTIVISTA

Directory of Open Access Journals (Sweden)

Roberta Chiesa Bartelmebs

Full Text Available O objetivo deste artigo é traçar um paralelo entre a obra Psicogênese e História das Ciências, de Piaget e García, com o ensino de ciências a partir de uma epistemologia construtivista, derivada essencialmente da epistemologia genética. A obra, publicada pela primeira vez em 1983, concretiza a síntese de suas investigações epistemológicas acerca do desenvolvimento das ciências através da história das ciências com o desenvolvimento da inteligência por meio da psicogênese. O objetivo do livro, no entanto, não é comparar a história das ciências com o desenvolvimento psicogenético dos sujeitos, mas compreender os mecanismos de evolução das ideias pré-científicas nas crianças através da epistemologia genética. Nesse sentido, os autores apresentam uma epistemologia construtivista, a qual, no nosso entendimento, pode servir de base para a compreensão do ensino de ciências, contribuindo com reflexões acerca dos processos de ensino e de aprendizagem em sala de aula.

A partir das propostas desses autores foram criados alguns modelos econométricos específicos a cada autor. Para testar esses modelos empíricos foi utilizada uma base de dados com 4.498 firmas industriais. Os principais resultados indicam a importância da inovação tecnológica, da inserção externa e das economias de escopo e escala na determinação das diferenças de lucratividade entre as firmas de uma mesma indústria.The paper is an empirical analyze of some theoretical propositions that relate the firm capabilities and structure to its sectoral performance. The firm performance was measured by its profitability, market share, and indexes of productivity. The determinants of the firm performance were based on the main arguments of Edith Penrose, Alfred Chandler, Richard Nelson and Sidney Winter, and some propositions of Stephen Hymer and Raymond Vernon. These theoretical propositions guide the shape of the econometric models specific to each author. To test the econometric models, it was used a database with 4,498 manufacturing firms. The main results show the importance of the technological innovation, the external trade, and the economies of scale and scope as determinants of the profit asymmetries among firms of an industry.

2010-05-01

Full Text Available Abstract Background Previous studies have analyzed the psychometric properties of the World Health Organization Disability Assessment Schedule II (WHO-DAS II using classical omnibus measures of scale quality. These analyses are sample dependent and do not model item responses as a function of the underlying trait level. The main objective of this study was to examine the effectiveness of the WHO-DAS II items and their options in discriminating between changes in the underlying disability level by means of item response analyses. We also explored differential item functioning (DIF in men and women. Methods The participants were 3615 adult general practice patients from 17 regions of Spain, with a first diagnosed major depressive episode. The 12-item WHO-DAS II was administered by the general practitioners during the consultation. We used a non-parametric item response method (Kernel-Smoothing implemented with the TestGraf software to examine the effectiveness of each item (item characteristic curves and their options (option characteristic curves in discriminating between changes in the underliying disability level. We examined composite DIF to know whether women had a higher probability than men of endorsing each item. Results Item response analyses indicated that the twelve items forming the WHO-DAS II perform very well. All items were determined to provide good discrimination across varying standardized levels of the trait. The items also had option characteristic curves that showed good discrimination, given that each increasing option became more likely than the previous as a function of increasing trait level. No gender-related DIF was found on any of the items. Conclusions All WHO-DAS II items were very good at assessing overall disability. Our results supported the appropriateness of the weights assigned to response option categories and showed an absence of gender differences in item functioning.

For more than fifteen years electromagnetic fields (EMFs) are intensively discussed in connection with health hazards in mass media as well as questions of standard setting by the authorities. The present elaboration gives an extended overview over the actual situation of the special electromagnetic hypersensitivity issue in relation to electromagnetic field research in the international scientific community. There are parallels and analogies between the symptoms of electromagnetic hypersensitivity and those of the Multiple-Chemical-Sensitivity-Syndrome and other environmental diseases. The first part deals with the biophysical fundamental knowledge of interactions between electromagnetic fields and biological systems such as man or animal including threshold values and threshold philosophy. Then hypothetical mechanisms of action of EMF are demonstrated, with a special focus on the melatonin hypothesis, which has not been proved in all its parts up to now. Additionally, in the context of our biomedical research into disorders of well-being we conducted an analysis of written and telephone questions about the EMF issue which are sent to our center. The results are of scientific and political interest and are demonstrated in detail. (orig.)

Full Text Available A special aspect of aircraft test is carrying out both flight evaluation and ground operation evaluation in a structure of flying aids and special tools equipment. The specific of flight and sea tests involve metering in offshore zone, which excludes the possibility of fixed geodetically related measuring tools. In this regard, the specific role is acquired by shipbased measurement systems, in particular the mobile modular measuring systems. Information processed in the mobile modular measurement systems is a critical resource having a high level of confidentiality. When carrying out their functions, it should be implemented a proper information control of the mobile modular measurement systems to ensure their protection from the risk of data leakage, modification or loss, i.e. to ensure a certain level of information security. Due to the specific of their application it is difficult to solve the problems of information security in such complexes. The intruder model, the threat model, the security requirements generated for fixed informatization objects are not applicable to mobile systems. It was concluded that the advanced mobile modular measuring systems designed for flight experiments monitoring and control should be created due to necessary information protection measures and means. The article contains a diagram of security requirements formation, starting with the data envelopment analysis and ending with the practical implementation. The information security probabilistic model applied to mobile modular measurement systems is developed. The list of current security threats based on the environment and specific of the mobile measurement system functioning is examined. The probabilistic model of the information security evaluation is given. The problems of vulnerabilities transformation of designed information system into the security targets with the subsequent formation of the functional and trust requirements list are examined.

With the aim of reducing greenhouse gas emissions, comprehensive climate protection measures have already been adopted both nationally and internationally. This raises the question of how economically and ecologically useful system infrastructure looks, which at the same time ensures the supply reliability of all consumers. The regenerative energy model (REMod) presented in this book has been developed to provide answers. The sectors electricity, heat, transport and industry are considered for the first time simultaneous in an energy system model. In particular, in order to satisfy the criterion of reliability of supply, the model calculates the energy flows in hourly resolution for the period from today (2015) to 2050. The system is optimized with regard to minimum overall costs and under the boundary condition that a maximum set quantity of permitted greenhouse gas emissions is not exceed. On the example of Germany (REMod-D), the results show that, in particular, the interaction of the sectors can lead to strong differences in the design of the system infrastructure. [German] Mit dem Ziel den Ausstoss der Treibhausgase zu reduzieren, wurden bereits national wie international umfangreiche Klimaschutzmassnahmen verabschiedet. Hieraus ergibt sich die Frage wie eine oekonomisch und oekologisch sinnvolle Systeminfrastruktur aussieht, die gleichzeitig die Versorgungssicherheit aller Verbraucher gewaehrleistet. Das in diesem Buch vorgestellte Regenerative Energien Modell (REMod) wurde entwickelt um hierauf Antworten zu liefern. Beruecksichtigt werden erstmalig in einem Energiesystemmodell die Sektoren Strom, Waerme, Verkehr und Industrie gleichzeitig. Insbesondere um dem Kriterium der Versorgungssicherheit gerecht zu werden, berechnet das Modell die Energiefluesse in stuendlicher Aufloesung fuer den Zeitraum von heute (2015) bis 2050.

2008-01-01

An advanced thrust-measurement system utilizes active magnetic bearings to both (1) levitate a floating frame in all six degrees of freedom and (2) measure the levitation forces between the floating frame and a grounded frame. This system was developed for original use in measuring the thrust exerted by a rocket engine mounted on the floating frame, but can just as well be used in other force-measurement applications. This system offers several advantages over prior thrust-measurement systems based on mechanical support by flexures and/or load cells: The system includes multiple active magnetic bearings for each degree of freedom, so that by selective use of one, some, or all of these bearings, it is possible to test a given article over a wide force range in the same fixture, eliminating the need to transfer the article to different test fixtures to obtain the benefit of full-scale accuracy of different force-measurement devices for different force ranges. Like other active magnetic bearings, the active magnetic bearings of this system include closed-loop control subsystems, through which the stiffness and damping characteristics of the magnetic bearings can be modified electronically. The design of the system minimizes or eliminates cross-axis force-measurement errors. The active magnetic bearings are configured to provide support against movement along all three orthogonal Cartesian axes, and such that the support along a given axis does not produce force along any other axis. Moreover, by eliminating the need for such mechanical connections as flexures used in prior thrust-measurement systems, magnetic levitation of the floating frame eliminates what would otherwise be major sources of cross-axis forces and the associated measurement errors. Overall, relative to prior mechanical-support thrust-measurement systems, this system offers greater versatility for adaptation to a variety of test conditions and requirements. The basic idea of most prior active

A measurement system to simultaneously measure six degree-of-freedom (6DOF) geometric errors is proposed. The measurement method is based on a combination of mono-frequency laser interferometry and laser fiber collimation. A simpler and more integrated optical configuration is designed. To compensate for the measurement errors introduced by error crosstalk, element fabrication error, laser beam drift, and nonparallelism of two measurement beam, a unified measurement model, which can improve the measurement accuracy, is deduced and established using the ray-tracing method. A numerical simulation using the optical design software Zemax is conducted, and the results verify the correctness of the model. Several experiments are performed to demonstrate the feasibility and effectiveness of the proposed system and measurement model.

Full Text Available Este artigo analisou a desigualdade ambiental em Rio das Ostras-RJ por meio do mapeamento das condições adequadas de habitação, baseada nos índices de abastecimento de água, de esgotamento sanitário, de alfabetização, de renda, de disposição do lixo e de presença de vegetação, oriundos do Censo IBGE de 2010 e de imagens de satélite Cbers-2b e Landsat-5, de 2008. Os índices foram ponderados pelo método Analitic Hierarchy Process e agregados no software ArcGis 10.0, construindo o índice de desigualdade ambiental. O município de Rio das Ostras foi selecionado por apresentar um elevado crescimento populacional entre 2000 e 2010, seguido de um significativo crescimento econômico derivado da exploração de petróleo e gás na Bacia de Campos. Nesse sentido, tornou-se importante verificar se o crescimento populacional e econômico vinha acompanhando de condições de habitação adequadas para toda a população. O resultado expôs a presença de desigualdade ambiental em Rio das Ostras, afetando principalmente a população de menor renda, com maiores porcentagens de analfabetos e localizados no limite da área urbanizada e na área rural, cujas áreas apresentaram deficiência na oferta de serviços e infraestrutura. Concluiu-se que a distribuição condições adequadas de habitação avaliada por este trabalho não é homogênea e segue a lógica de valorização da terra urbana para o processo de especulação imobiliária em Rio das Ostras. A presença da desigualdade ambiental também representa dificuldades na garantia da sustentabilidade urbana, com diversas áreas desprovidas de condições de habitação em que, por isso, acabam por impactar o meio ambiente.

"Doidas e putas”: usos das categorias travesti e transexual

Bruno Cesar Barbosa

Full Text Available Neste artigo discuto os usos das categorias travesti e transexual com base em trabalho de campo realizado entre 2008 e 2009 com participantes das reuniões denominadas Terças Trans. A questão central que norteou a análise foi como as diferentes pessoas observadas utilizavam categorias relacionadas a identidades sexuais e de gênero e como acionavam e articulavam diversas associações convencionais nesse processo para produzir sentidos e diferenças acerca destas categorias. Embora as convenções do discurso médico sejam referências centrais para a definição de corpos, subjetividades e identidades das pessoas pesquisadas, foi possível observar também uma variedade de reelaborações e deslocamentos de sentidos. Procuro desenvolver o argumento de que travesti e transexual são categorias performativas, e que tal performatividade não se esgota apenas em enunciados de gênero e sexualidade, mas também pode ser expressa por meio de articulações contingentes que remetem a diferenças de classe, cor/raça e geração.

Apesar das funções dos microrganismos no crescimento das plantas e na produtividade das culturas, existem poucas informações dos efeitos resultantes do manejo do solo, na ecologia microbiana. Neste estudo, foram avaliados os efeitos das condições ambientais e das práticas agrícolas sobre as populações bacterianas. As densidades das populações em solos com vegetação nativa foram variáveis e diferenciadas. Em Sete Lagoas, MG, as populações de actinomicetos variaram de 1,7 a 50 X 10(4 UFC/g de solo seco, enquanto em Planaltina as densidades das populações bacterianas em solo com primeiro e segundo ano de cultivo de soja foram semelhantes, mas superiores ao solo com vegetação nativa. A utilização agrícola deste solo não resultou em desequilíbrios acentuados das populações de actinomicetos provenientes de esporos e hifas. As relações esporos/hifas variaram de 1,1 a 5,8. Na rizosfera da soja, os coeficientes de correlação entre as populações de actinomicetos com as demais populações bacterianas foram significativos. Os resultados evidenciam que as práticas agrícolas utilizadas na introdução da cultura da soja em solos de Cerrados pode influenciar o equilíbrio das populações na comunidade bacteriana.Among tropical environments, Cerrados stand out because of its agriculture potencial. Although microorganisms play an important role on soil sustainability and crop production, few information is available on the effects of soil management systems on Cerrado's microbial ecology. In this study the effects of environmental conditions and soil management practices on bacterial populations were evaluated.

Full Text Available RESUMEN Las caídas son “acontecimientos involuntarios que hacen perder el equilibrio y dar con el cuerpo en la tierra u otra superficie firme que lo detenga”. Las caídas recurrentes (presencia de dos o más caídas en un año constituyen un problema frecuente en centros residenciales, y predisponen a las personas mayores a sufrir incapacidad, dependencia y múltiples enfermedades. La aplicación de medidas de prevención puede disminuir notablemente su incidencia y, por tanto, sus consecuencias. El objetivo de este trabajo es identificar qué intervenciones de enfermería pueden ayudar a prevenir caídas recurrentes en las personas mayores institucionalizadas, y minimizar el impacto emocional que ocasionan estos episodios. Para ello, se desarrolla un caso clínico y, tras el análisis de la evidencia científica, se proponen intervenciones para evitar la recurrencia de un episodio de caída y sus consecuencias. El análisis de este caso se estructura en valoración de riesgo de caídas recurrentes e intervenciones de prevención de las mismas. Y, a su vez, cada apartado se divide en aspectos físicos y emocionales. La literatura especializada refleja que la valoración del riesgo de caídas es clave para implantar un plan de cuidados. Conocer los factores de riesgo intrínsecos y extrínsecos ayudará a los profesionales a diseñar intervenciones de prevención. Asimismo, se ha identificado el impacto emocional que producen las caídas en los pacientes y se proponen algunas intervenciones para aliviarlo. Este trabajo refuerza la importancia de realizar una adecuada valoración de enfermería a las personas mayores en riesgo de sufrir caídas recurrentes, a través de diferentes instrumentos para detectar las áreas específicas de intervención. Se concluye con la necesidad de protocolizar esta valoración, tanto física como emocional, para poder individualizarla posteriormente con cada paciente.

Full Text Available Validasi data TRMM telah dilakukan dengan data curah hujan di tiga DAS di wilayah Indonesia. Ketiga DAS tersebut adalah: DAS Citarum-Jawa Barat, DAS Sutami-Brantas Jawa Timur dan DAS Larona-Sulawesi Selatan. Dari analisis dua jenis tipe data TRMM NASA (3B42RT dan TRMM Jaxa (GSMap_NRT menunjukkan bahwa TRMM Jaxa lebih mendekati data pengamatan dibandingkan dengan TRMM NASA. Secara umum dari hasil analisis untuk ketiga DAS memperlihatkan bahwa nilai curah hujan TRMM Jaxa (GSMap_NRT mempunyai pola yang mengikuti curah hujan pengamatan (aktual meskipun nilainya cenderung di bawah perkiraan. Perbedaan ini salah satunya bisa diakibatkan karena pemasangan penakar hujan yang kurang representatif terhadap DAS sehingga rerata curah hujan wilayahnya kurang merepresentasikan DAS tersebut. Untuk plot scatter bulanan nilai korelasinya lebih baik dibandingkan dengan plot scatter harian (dari 0.13~0.14 meningkat menjadi 0.58~0.75 dan nilai RMSE menurun (dari rerata 11.6 mm/hari menjadi 7.6 mm/hari, sehingga analisis TRMM bulanan lebih merepresentasikan kondisi aktual.   TRMM data validation has been done with rainfall data in three watersheds of Indonesia. There are: Citarum (West Java, Sutami-Brantas (East Java and Larona (South Sulawesi. There are two types of TRMM data; TRMM NASA (3B42RT and TRMM Jaxa (GSMap_NRT. From the analysis of both types of the data indicate that the TRMM Jaxa closer to observed data. In general the results of analysis for all three catchments showed that the value of TRMM rainfall Jaxa (GSMap_NRT has better agreement to the pattern of observed rainfall data although it's value tend to under estimate. This difference could be caused due to the installation of the rain gauge less representative of catchment so that the average rainfall less territory represents the catchment. Scatter plot for the monthly data have better correlation coefficient than the daily plot (0.13~0.14 raise 0.58~0.75 and decreasing RMSE value (from average 11

A measurement system for diffraction efficiency of convex gratings is designed. The measurement system mainly includes four components as a light source, a front system, a dispersing system that contains a convex grating, and a detector. Based on the definition and measuring principle of diffraction efficiency, the optical scheme of the measurement system is analyzed and the design result is given. Then, in order to validate the feasibility of the designed system, the measurement system is set up and the diffraction efficiency of a convex grating with the aperture of 35 mm, the curvature-radius of 72mm, the blazed angle of 6.4°, the grating period of 2.5μm and the working waveband of 400nm-900nm is tested. Based on GUM (Guide to the Expression of Uncertainty in Measurement), the uncertainties in the measuring results are evaluated. The measured diffraction efficiency data are compared to the theoretical ones, which are calculated based on the grating groove parameters got by an atomic force microscope and Rigorous Couple Wave Analysis, and the reliability of the measurement system is illustrated. Finally, the measurement performance of the system is analyzed and tested. The results show that, the testing accuracy, the testing stability and the testing repeatability are 2.5%, 0.085% and 3.5% , respectively.

This article reported: (1) the outline of the reactivity measurement system of Kyoto University Research Reactor (KUR), (2) the calibration data of control rod, (3) the problems and the countermeasures for range switching of linear output meter. For the laptop PC for the reactivity measurement system, there are four input signals: (1) linear output meter, (2) logarithmic output meter, (3) core temperature gauge, and (4) control rod position. The hardware of reactivity measurement system is controlled with Labview installed on the laptop. Output, reactivity, reactor period, and the change in reactivity due to temperature effect or Xenon effect are internally calculated and displayed in real-time with Labview based on the four signals above. Calculation results are recorded in the form of a spreadsheet. At KUR, the reactor core arrangement was changed, so the control rod was re-calibrated. At this time, calculated and experimental values of reactivity based on the reactivity measurement system were compared, and it was confirmed that the reactivity calculation by Labview was accurate. The range switching of linear output meter in the nuclear instrumentation should automatically change within the laptop, however sometimes this did not function properly in the early stage. It was speculated that undefined percent values during the transition of percent value were included in the calculation and caused calculation errors. The range switching started working properly after fixing this issue. (S.K.)

Radionuclide measuring systems and improved methods of evaluation for the measurement of wear in stationary and mobile systems

Lausch, W.

1976-01-01

A newly developped flow through measuring unit makes it possible to perform continuous wear measurements on stationary and mobile systems. It was specifically designed for measurements on engine components of passenger cars. For tests of long duration an oil sampling technique was developed. Fully automated measurements are achieved with a sampling device suitable for both stationary and mobile systems. For systems with oil consumption a mathematical model provides for the necessary connection of the loss of wear particles through oil consumption. In certain cases an empirical graphical method can achieve nearly the same results. (orig.) [de

Full Text Available Pesquisas sobre estrutura de capital das empresas são consideradas dentre as mais relevantes na área de finanças. Diversas abordagens teóricas têm sido discutidas e testadas na literatura financeira. Este estudo buscou analisar o nível de endividamento das maiores empresas brasileiras, à luz das duas principais teorias que versam sobre o assunto, a teoria de Pecking Order e a teoria de trade--off, testando seus determinantes. A teoria do Pecking Order sugere a existência de uma hierarquia no uso de fontes de recursos, enquanto a teoria de trade-off considera a existência de uma estrutura meta de capital que seria perseguida pela empresa. O estudo é uma adaptação do artigo de Gaud et al. (2005, cujo trabalho serviu como base e principal referência para a escolha das principais variáveis e dos testes econométricos realizados. Tal como Gaud et al. (2005, desenvolvemos as análises estatísticas utilizando a metodologia de Panel Data, que considera os dados da amostra em corte transversal e longitudinal. Além de testes estáticos, foram feitos testes dinâmicos, com o objetivo de analisar o processo de ajuste da estrutura de capital ao longo do tempo, em direção a um suposto nível-alvo ótimo. Os resultados demonstraram relação negativa entre o nível de endividamento das empresas e o grau de tangibilidade dos ativos e a rentabilidade, bem como relação positiva do endividamento com o risco. Demonstraram ainda que empresas de capital estrangeiro são mais endividadas que empresas nacionais. De um modo geral, os resultados sugerem que a teoria de Pecking Order é mais consistente do que a teoria de trade-off para explicar a estrutura de capital das companhias abertas brasileiras. Em especial, destacamos a relação negativa entre endividamento e rentabilidade, confirmando vários outros resultados de pesquisa obtidos na realidade brasileira.

This book illustrates how much of our environment we use up with the products and services associated with everyday life, how large the ecological impact of our consume society actually is; we build roads, dams, heavy goods vehicles, warehouses, factories, monocultures and rubbish tips. We take iron ore, sand, gravel, coal oil, water, air and wood from our environment in huge, ever-increasing qualities. Slag heaps, erosion and disrupted water flow are left behind. This man-made materialistic society is altering nature`s balance persistently and for the long term. This materialism is no longer ecologically sustainable. We must learn to prosper with less negative environmental impacts. The author has developed a means of measuring the intensity of environmental impact of products, processes and services, based on the material consumed to allow acurate comparisons. In this comprehensible informative book he reveals, for the first time publicly, the measure/formula by means of many practical examples and illustrations to show a way out of the crisis.

Em relação ao ambiente industrial, elevados custos são imputados à indústria em virtude de deficiências no ciclo informacional e no de mercadorias. Falhas ocasionam interrupções e rupturas nesses ciclos, reduzindo a competitividade das organizações. O trabalho debruça-se sobre a possibilidade de categorizar essas falhas na cadeia de suprimentos. O objetivo principal é, a partir de um olhar da Ciência da Informação (CI, propor uma taxonomia para as falhas existentes, tendo por base os seguintes objetivos: (i identificar as principais falhas nas cadeias de suprimentos evidenciadas na literatura; (ii posicionar cada falha dentro do fluxo logístico e informacional, e (iii agrupar, organizar e hierarquizar essas falhas. Trata-se uma pesquisa bibliográfica, exploratória e qualitativa. Os resultados obtidos permitem afirmar que existem diversas similaridades nos termos que definem os locais e a origem das ocorrências de falhas, assim como, a percepção de que, com base na taxonomia proposta, há elevados riscos de interrupções e rupturas na cadeia de suprimentos. Finalmente, com o trabalho, espera-se contribuir com a ampliação da compreensão das falhas que acometem diversas organizações e, igualmente, com a geração de conhecimento para discussões futuras que envolvam as cadeias de suprimentos e a Ciência da Informação.

Die von den nacheinander folgenden Familienvertretern gesammelten Materialien, die sich bis zum heutigen Tag bewährten, erlauben die wichtigsten Schicksale dieser Familie wiederherzustellen. Die Szwojnickis waren eine Familie der Landesbeamten. Im 19. Jahrhundert waren ihre Landgüter in Borkłojnie ein Hort, wo die polnischen Truppen während des Januaraufstandes unterstützt, geschützt und versorgt wurden. Die Landgüter wurden von 1897 bis zum Ende des Zweiten Weltkrieges von Zygmunt Szwojnicki verwaltet. In der Zwischenkriegszeit bemühte er sich aktiv um die Bewahrung der nationalen Identität der in der Republik Litauen lebenden Polen. 1946 wurde er zusammen mit anderen Polen in den polnischen Staat umgesiedelt. Das ganze Familienarchiv Szwojnickis ist einer der kleineren Archivbestände, die in der Universitätsbibliothek in Thorn aufbewahrt werden. Dazu gehörten insgesamt 12 Inventareinheiten. Das älteste Dokument in diesem Bestand stammt aus dem Jahr 1531, das jüngste aus dem Jahr 1946. Die erhaltenen Archivalien entstanden also innerhalb von über 400 Jahren. Sie schildern die Schicksale der Familie Szwojnicki und ihrer Landgüter in Borkłojnie.

Full Text Available Neste trabalho, teve-se como objetivo identificar o impacto do risco de liquidez nos retornos excedentes esperados das debêntures no mercado secundário brasileiro. Foram realizadas análises de regressão em painel desbalanceado com dados semestrais de 101 debêntures ao longo de oito semestres (primeiro semestre de 2006 ao segundo semestre de 2009, totalizando 382 observações. Sete proxies (spread de compra e venda, %zero returns, idade, volume de emissão, valor nominal de emissão, quantidade emitida e %tempo foram utilizadas para testar o impacto do risco de liquidez nos yield spreads das debêntures. O yield spread foi controlado por até dez outras variáveis determinantes que não a liquidez (fator de juros, fator de crédito, taxa livre de risco, rating, duration, quatro variáveis contábeis e volatilidade de equity. A hipótese nula de que não há prêmio de liquidez para o mercado secundário de debêntures no Brasil foi rejeitada apenas para três das sete proxies (spread de compra e venda, valor nominal de emissão e quantidade emitida. Os prêmios encontrados são bastante baixos (1,9 basis point para cada 100 basis point de incremento no spread de compra e venda, 0,5 basis point para um aumento de 1% no valor do valor nominal de emissão e 0,17 basis point para cada menos 1.000 debêntures emitidas. De qualquer forma, houve perda na eficiência das proxies de liquidez após correção das autocorrelações e potenciais endogeneidades, seja por meio da inclusão de efeitos fixos, da análise de primeiras diferenças ou da utilização de um sistema de três equações. Esses resultados apontam para a suspeita de que o risco de liquidez não é um fator importante na composição das expectativas dos investidores no mercado secundário de debêntures.

Automatic measurement system for light element isotope analysis

International Nuclear Information System (INIS)

Satake, Hiroshi; Ikegami, Kouichi.

1990-01-01

The automatic measurement system for the light element isotope analysis was developed by installing the specially designed inlet system which was controlled by a computer. The microcomputer system contains specific interface boards for the inlet system and the mass spectrometer, Micromass 602 E. All the components of the inlet and the computer system installed are easily available in Japan. Ten samples can be automatically measured as a maximum of. About 160 minutes are required for 10 measurements of δ 18 O values of CO 2 . Thus four samples can be measured per an hour using this system, while usually three samples for an hour using the manual operation. The automatized analysis system clearly has an advantage over the conventional method. This paper describes the details of this automated system, such as apparatuses used, the control procedure and the correction for reliable measurement. (author)

Dereplication, Aggregation and Scoring Tool (DAS Tool) v1.0

Energy Technology Data Exchange (ETDEWEB)

2017-03-01

Communities of uncultivated microbes are critical to ecosystem function and microorganism health, and a key objective of metagenomic studies is to analyze organism-specific metabolic pathways and reconstruct community interaction networks. This requires accurate assignment of genes to genomes, yet existing binning methods often fail to predict a reasonable number of genomes and report many bins of low quality and completeness. Furthermore, the performance of existing algorithms varies between samples and biotypes. Here, we present a dereplication, aggregation and scoring strategy, DAS Tool, that combines the strengths of a flexible set of established binning algorithms. DAS Tools applied to a constructed community generated more accurate bins than any automated method. Further, when applied to samples of different complexity, including soil, natural oil seeps, and the human gut, DAS Tool recovered substantially more near-complete genomes than any single binning method alone. Included were three genomes from a novel lineage . The ability to reconstruct many near-complete genomes from metagenomics data will greatly advance genome-centric analyses of ecosystems.

Automated statistical modeling of analytical measurement systems

International Nuclear Information System (INIS)

Jacobson, J.J.

1992-01-01

The statistical modeling of analytical measurement systems at the Idaho Chemical Processing Plant (ICPP) has been completely automated through computer software. The statistical modeling of analytical measurement systems is one part of a complete quality control program used by the Remote Analytical Laboratory (RAL) at the ICPP. The quality control program is an integration of automated data input, measurement system calibration, database management, and statistical process control. The quality control program and statistical modeling program meet the guidelines set forth by the American Society for Testing Materials and American National Standards Institute. A statistical model is a set of mathematical equations describing any systematic bias inherent in a measurement system and the precision of a measurement system. A statistical model is developed from data generated from the analysis of control standards. Control standards are samples which are made up at precise known levels by an independent laboratory and submitted to the RAL. The RAL analysts who process control standards do not know the values of those control standards. The object behind statistical modeling is to describe real process samples in terms of their bias and precision and, to verify that a measurement system is operating satisfactorily. The processing of control standards gives us this ability

Distance and Cable Length Measurement System

Science.gov (United States)

Hernández, Sergio Elias; Acosta, Leopoldo; Toledo, Jonay

2009-01-01

A simple, economic and successful design for distance and cable length detection is presented. The measurement system is based on the continuous repetition of a pulse that endlessly travels along the distance to be detected. There is a pulse repeater at both ends of the distance or cable to be measured. The endless repetition of the pulse generates a frequency that varies almost inversely with the distance to be measured. The resolution and distance or cable length range could be adjusted by varying the repetition time delay introduced at both ends and the measurement time. With this design a distance can be measured with centimeter resolution using electronic system with microsecond resolution, simplifying classical time of flight designs which require electronics with picosecond resolution. This design was also applied to position measurement. PMID:22303169

Full Text Available Investigamos as concepções das crianças sobre as relações de gênero e sobre as funções da avaliação na experiência escolar. Com base na abordagem sociocultural construtivista, objetivamos identificar aspectos semióticos de ordem da cultura na narrativa das crianças de forma a compreender a construção as relações de gênero na escolarização. Observamos duas sessões de grupo focal, uma com quatro meninos e outra com cinco meninas de quarta série. Utilizamos uma metodologia qualitativa interpretativa para análise das interações comunicativas. Verificamos que as relações de poder entre os gêneros aparecem já com bastante clareza na narrativa das crianças mediante articulação da cultura coletiva, como a naturalização da violência, a associação do universo feminino à esfera doméstica e do universo masculino à esfera pública e a negociação recíproca das posições assimétricas de controle e vitimização. Entretanto, verificamos que essa relação aparece apenas em parte quando se referem ao contexto escolar, à situações de aprendizagem e avaliação, narrando experiências de igualdade de tratamento e expectativas, especialmente por parte das professoras

Violência e sofrimento social: a resistência feminina na obra de Veena Das Violence and Social Suffering: women's resistance in Veena Das' works

Full Text Available O sofrimento social vem sendo discutido por pesquisadores brasileiros em diferentes contextos, normalmente associado às populações socialmente excluídas, vítimas de violência e da miséria crônica, com atenção especial para sua repercussão nos corpos de mulheres e crianças. Neste trabalho discute-se o conceito de sofrimento social, que tem como referência a Antropologia Médica a partir dos trabalhos da antropóloga indiana Veena Das, buscando diálogo com questões de gênero e saúde em nosso meio. A importância dessas concepções é investigada nos trabalhos de Das sobre a resistência do feminino no imaginário e no cotidiano, nos quais esta resistência aos discursos hegemônicos em meio à violência e ao sofrimento social se apresenta de maneira sutil nos usos cotidianos dos corpos. Concluindo, a posição sobre a resistência feminina na perspectiva de Veena Das pode ser útil para estudos e intervenções no campo da saúde, realizados com mulheres brasileiras de populações em situação de miséria crônica em contextos de sofrimento e exclusão social. A escuta de mulheres jovens e pobres a respeito da maneira como (não dirigem seus destinos e elaboram projetos de vida, aponta para a possibilidade de investigar fenômenos que remetem aos mesmos cenários descritos por Das. A busca de sua inserção em movimentos imaginários que se materializam em suas falas e nos usos e cuidados com seus corpos pode ser decisiva para, em contextos de promoção de saúde, dar entendimento e intervir sobre processos que parecem sem sentido, mas que guardam na sua incompletude e incerteza a marca indelével do humano.Social suffering has been studied in several circumstances by Brazilian researchers, usually associated with socially excluded people who are victims of violence and chronic poverty. Special attention has been given to its effects on women's and children's bodies. In this work, we deal with the Medical Anthropology concept

Data Acquisition System Design for Advanced Core-Cooling Mechanism Experiment

International Nuclear Information System (INIS)

Zhang, Ziyang; Tian, Fang; Zhang, Tao; Wang, Shen

2011-01-01

Data Acquisition System (DAS) design for Advanced Core-Cooling Mechanism Experiment(ACME) is studied in the paper. DAS is an important connection between test facility and result analysis. Firstly, it introduces DAS and its design requirement for ACME. Nearly one thousand data resources need record in ACME. They have different types and acquisition frequencies. In order to record these data, a large scale and high speed layered data acquisition system is developed. Secondly, it discusses the DAS design for ACME, including the analog signal adjusting circuits, clock circuit design, sampling frequencies, data storage and transmission by large database system, anti-interference and etc. Analog signal adjusting circuits are necessary to deal with different kinds of input data to gain standard data resources. Some data change slowly and others change in several seconds according to the test performed on ACME. So it is difficult to use uniform sampling frequencies, and a layered data acquisition system is introduced. A large database is built to store data for ACME test, which keeps data safer and makes subsequent data handling more convenient. A database hot backup is also applied to ensure data safety. The software of DAS is built by Labview, which can provide intuitionist result and friendly interface. Another important function of DAS is the ACME safety protection. Finally, the characteristics and improvement of DAS for ACME is analyzed compared to other test facility. Besides friendly user interface, DAS of ACME can also assure higher data precision and sampling frequency

GPS synchronized power system phase angle measurements

Science.gov (United States)

Wilson, Robert E.; Sterlina, Patrick S.

1994-09-01

This paper discusses the use of Global Positioning System (GPS) synchronized equipment for the measurement and analysis of key power system quantities. Two GPS synchronized phasor measurement units (PMU) were installed before testing. It was indicated that PMUs recorded the dynamic response of the power system phase angles when the northern California power grid was excited by the artificial short circuits. Power system planning engineers perform detailed computer generated simulations of the dynamic response of the power system to naturally occurring short circuits. The computer simulations use models of transmission lines, transformers, circuit breakers, and other high voltage components. This work will compare computer simulations of the same event with field measurement.

Ground-truth measurements of precipitation and related weather events are an essential component of any satellite system designed for monitoring rainfall from space. Such measurements are required for testing, evaluation, and operations; they provide detailed information on the actual weather events, which can then be compared with satellite observations intended to provide both quantitative and qualitative information about them. Also, very comprehensive ground-truth observations should lead to a better understanding of precipitation fields and their relationships to satellite data. This process serves two very important functions: (a) aiding in the development and interpretation of schemes of analyzing satellite data, and (b) providing a continuing method for verifying satellite measurements.

A China na ordem ambiental internacional das mudanças climáticas

Directory of Open Access Journals (Sweden)

HELENA MARGARIDO MOREIRA

Full Text Available resumo As mudanças climáticas são consideradas um dos grandes desafios globais do século XXI. A China, como ator global e principal emissor de gases de efeito estufa, é um país-chave na política climática internacional. Sua posição é fundamental para o desenho do acordo futuro que substituirá o Protocolo de Kyoto e que regulará a ação humana sobre o sistema climático terrestre, dando continuidade ao conjunto de decisões internacionais que formam a ordem ambiental internacional das mudanças climáticas. Atendo-se à defesa do princípio das "responsabilidades comuns, porém diferenciadas", a China vem construindo seu posicionamento como um dos protagonistas dessa ordem desde o seu início, com a assinatura da Convenção do Clima em 1992. Este artigo parte do argumento de que a postura chinesa nas negociações internacionais sobre mudanças climáticas, apesar de muito participativa e fundamental para o encaminhamento das decisões globais sobre o tema, é definida em termos do interesse desenvolvimentista do Estado chinês. Durante as negociações das Conferências analisadas, a China agiu como liderança do G77 e em defesa dos seus próprios interesses, buscando garantir as responsabilidades diferenciadas e a classificação da China como país em desenvolvimento, evitando comprometer seus objetivos domésticos de desenvolvimento econômico. A última Conferência do Clima, em Lima, 2014, manteve o princípio das responsabilidades diferenciadas reforçando o interesse chinês, ainda que tenha estabelecido que todos os países apresentem metas voluntárias de redução das emissões.

Purpose - Healthcare productivity is a growing issue in most Western countries where healthcare expenditure is rapidly increasing. Therefore, accurate productivity metrics are essential to avoid sub-optimization within a healthcare system. The purpose of this paper is to focus on healthcare production system productivity measurement. Design/methodology/approach - Traditionally, healthcare productivity has been studied and measured independently at the unit, organization and system level. Suggesting that productivity measurement should be done in different levels, while simultaneously linking productivity measurement to incentives, this study presents the challenges of productivity measurement at the different levels. The study introduces different methods to measure productivity in healthcare. In addition, it provides background information on the methods used to measure productivity and the parameters used in these methods. A pilot investigation of productivity measurement is used to illustrate the challenges of measurement, to test the developed measures and to prove the practical information for managers. Findings - The study introduces different approaches and methods to measure productivity in healthcare. Practical implications - A pilot investigation of productivity measurement is used to illustrate the challenges of measurement, to test the developed measures and to prove the practical benefits for managers. Originality/value - The authors focus on the measurement of the whole healthcare production system and try to avoid sub-optimization. Additionally considering an individual patient approach, productivity measurement is examined at the unit level, the organizational level and the system level.

Full Text Available In diesem Beitrag deuten wir nach der Parmenides Inspiration zwei Wege der menschlichen Wanderung zur Wahrheit an. In Denkensgeschichte war ein Weg der begründeten Erkenntnis bevorzugt, auf dem wir gerade das aussuchen, was als haltbar im Änderungsprozess überdauert. Auf diesem Weg können wir ein souveränes denkendes Subjekt treffen, das wegen seiner Rationalität ein fester Grund beim Erkennen der Welt geworden ist. Am Anfang des 20. Jahrhunderts hat Martin Heidegger darauf hingewiesen, dass im altäglichen Leben unserer Erkenntnis das Verständnis dessen vorangeht, was wir besorgen. Heidegger hat also einen anderen Weg auserwählt, auf dem er bemerkt, dass für einen Mensch eher als seine Rationalität das Abfinden mit seiner faktischen Existenz charakteristisch ist. Heideggers Dasein ist nicht mehr ein Souverän, sondern eine Existenz, die sich um Seinsverständnis bemüht. Ungefähr ab 1930 finden wir eine Kehre im Heideggers Denken. Er sucht einen neuen Weg, auf dem er eine Ek-sistenz vorstellen will.

Mobile car-borne measurement systems are an important asset in early phase emergency response in all Nordic countries. However, through the development of the systems in the different countries, there are considerable differences between the systems developed. This complicates Nordic cooperation and mutual assistance in emergency situations. This project aimed to facilitate harmonization of mobile measurement systems between the Nordic countries. The project focused on harmonizing data formats, information exchange and measurement strategies. Although the work done was funded by each member, the project established a good platform for cooperation which will hopefully continue beyond the scope of the project. A two-day seminar was held in May 2012, where all participants presented the current status (equipment, methods used etc.), in addition to invited speakers presenting development within the field of mobile detection and in situ measurements. Exchange of experiences and information on different measurement systems and practises in use was an important part of the seminar. The seminar was followed up by a small workshop during the REFOX exercise in Lund, Sweden, September 2012. Exchange of measurement data from the exercise was facilitated through a workspace proveded by NRPA as part of the MOMS project. The work done in this project will be presented at the NordEx12 seminar in March 2013. (Author)

Reflexões sobre o estatuto epistemológico das CSH: uma revisão das categorias verdade, sujeito e subjetividade

Directory of Open Access Journals (Sweden)

Pamella Rochelle Oliveira

2015-12-01

Full Text Available O presente ensaio teórico tem como objetivo discutir o conceito de verdade com ênfase nas obras de Friedrich Nietzsche e Michel Foucault, percebendo a temática como um dos conceitos chaves para se pensar o estatuto epistemológico das Ciências Sociais e Humanas (CSH na atualidade, já que o mesmo se faz intrinsicamente ligado a condições de possibilidades dadas, incidindo por sua vez na questão da produção de subjetividades, bem como do próprio sujeito, na medida em que estes são produzidos a partir e numa teia de relações invisíveis pautada em jogos de verdades e relações de poder. Para tanto, optamos num primeiro momento por realizar uma breve discussão acerca dos principais conflitos epistemológicos no campo das CSH, entre eles a antiga dualidade entre individuo x social, bem como a questão de causa e feito.

Relation between environmental variables and the fish community structure in streams of das Mortes and Xingu river basins – MT, Brazil

Full Text Available Environmental variables may determine and structure the composition of fish fauna. Studies comparing differences between physical and chemical variables of water between close river basins are few. This paper aimed to check which limnological variables are related to the distribution of fish species in two river basins. For this, 20 streams were sampled, divided between das Mortes and Xingu river basins. At each point one measured a total of 8 environmental variables. Fishes were collected through trawl. Total richness was 57 species, 29 of them from Xingu river basin, 35 from das Mortes river basin, and 7 species common to both river basins. The analyses showed that the streams in these two basins have distinct limnological and faunal features. The streams in Xingu river basin had lower pH values which may have been influenced by the high rates of organic decomposition. The streams of das Mortes river showed higher values of suspended matter and chlorophyll, probably due to higher degradation of streams and lower vegetation cover levels.

Das fantasias vazias ao referencial discursivo

Full Text Available Pretende-se analisar o estatuto de uma modalidade peculiar de fantasmatização para a qual propomos o nome de 'fantasias vazias'. No campo das fantasias vazias, a ambigüidade e a polissemia das palavras são postas de lado e seus enunciados se tornam absolutos e unívocos, de modo a anularem quaisquer possibilidades metafóricas ou simbólicas. Investigamos os limites que as fantasias em questão impõem à teoria do significante, propondo, em seguida, concebê-las como uma escritura balizada por uma série de elementos que denominamos 'referenciais discursivos'.From empty fantasies to dissertational reference. The purpose of the article is to analyze the state of a peculiar modality of fantasizing which we have named empty fantasies. Thus, in the field of empty fantasies, the ambiguity and the multiple meaning of the words are put aside and, for that reason, their statement becomes obsolete and univocal, in a way that they eliminate any metaphoric or symbolic possibilities. We investigate the limits that those fantasies impose to the theory of the signifier, proposing, then, to conceive them as a writing delimitated by a series of elements that we have called discourse references.

Als Literaturwissenschaftlerin und ehemalige Naturwissenschaftlerin glaube ich, dass wir das Leben nur verstehen werden, wenn wir seinen Wirkungen überall nachforschen, inklusive in der Literatur.

Review Essay: Das dialogische Selbst zwischen simultaner Pluralität und Halt verleihenden Sprachpraktiken

Full Text Available "Das dialogische Selbst" von Frank-M. STAEMMLER ist ein wichtiger Beitrag zu einem dialogischen Menschenbild, das von verschiedenen Seiten als Alternative zur methodologischen Individualismus formuliert wird. Der Zusammenhang zwischen einer dialogischen Theorie des Selbst und konkreten therapeutischen Techniken wird einleuchtend hergestellt; klar wird dabei, dass dialogisches Denken eine Herausforderung an tradierte Denkmuster ist. Es sabotiert die Denkfigur der "abgelösten Vorgängigkeit" (BERTAU 2015 (von "Ich", "Selbst" zugunsten des je tatsächlichen Geschehens. Allerdings können Pluralität und Dynamik, Performativität und Gegenwärtigkeit des Geschehens ihrerseits nicht beliebig sein und bloß emergent, sie erfahren vielmehr eine Struktur, ohne die sie nicht (wieder- erkennbar wären. Wie das Verhältnis von Geschehen und Struktur zu denken ist, scheint mir eine der Kernfragen des dialogischen Denkens zu sein. Nach einer formalen Betrachtung und inhaltlichen Übersicht des Buchs diskutiere ich diese Frage entlang STAEMMLERs eigenen Ideen über zwei Themen: Pluralität und Sprache. Das Verhältnis von Geschehen und Struktur ist demnach über die sprachliche Form in der Zeit, über die Zeit, zu denken. Angeredetwerden von einem "Du", das immer auch das allgemeine "Man" (oder "Wir" stellvertritt, verleiht dem "Ich" als dialogischem Selbst Stabilität in der Vielfalt. Der Schritt zur Öffnung der Intersubjektivität ins Öffentliche wird damit als notwendiges Moment zur Überwindung des Individualismus angesehen.

Magnetic Field Response Measurement Acquisition System

Science.gov (United States)

Woodard, Stanley E.; Taylor,Bryant D.; Shams, Qamar A.; Fox, Robert L.

2007-01-01

This paper presents a measurement acquisition method that alleviates many shortcomings of traditional measurement systems. The shortcomings are a finite number of measurement channels, weight penalty associated with measurements, electrical arcing, wire degradations due to wear or chemical decay and the logistics needed to add new sensors. Wire degradation has resulted in aircraft fatalities and critical space launches being delayed. The key to this method is the use of sensors designed as passive inductor-capacitor circuits that produce magnetic field responses. The response attributes correspond to states of physical properties for which the sensors measure. Power is wirelessly provided to the sensing element by using Faraday induction. A radio frequency antenna produces a time-varying magnetic field used to power the sensor and receive the magnetic field response of the sensor. An interrogation system for discerning changes in the sensor response frequency, resistance and amplitude has been developed and is presented herein. Multiple sensors can be interrogated using this method. The method eliminates the need for a data acquisition channel dedicated to each sensor. The method does not require the sensors to be near the acquisition hardware. Methods of developing magnetic field response sensors and the influence of key parameters on measurement acquisition are discussed. Examples of magnetic field response sensors and the respective measurement characterizations are presented. Implementation of this method on an aerospace system is discussed.

DasR is a pleiotropic regulator required for antibiotic production, pigment biosynthesis, and morphological development in Saccharopolyspora erythraea.

The GntR-family transcription regulator, DasR, was previously identified as pleiotropic, controlling the primary amino sugar N-acetylglucosamine (GlcNAc) and chitin metabolism in Saccharopolyspora erythraea and Streptomyces coelicolor. Due to the remarkable regulatory impact of DasR on antibiotic production and development in the model strain of S. coelicolor, we here identified and characterized the role of DasR to secondary metabolite production and morphological development in industrial erythromycin-producing S. erythraea. The physiological studies have shown that a constructed deletion of dasR in S. erythraea resulted in antibiotic, pigment, and aerial hyphae production deficit in a nutrient-rich condition. DNA microarray assay, combined with quantitative real-time reverse transcription PCR (qRT-PCR), confirmed these results by showing the downregulation of the genes relating to secondary metabolite production in the dasR null mutant. Notably, electrophoretic mobility shift assays (EMSA) showed DasR as being the first identified regulator that directly regulates the pigment biosynthesis rpp gene cluster. In addition, further studies indicated that GlcNAc, the major nutrient signal of DasR-responsed regulation, blocked secondary metabolite production and morphological development. The effects of GlcNAc were shown to be caused by DasR mediation. These findings demonstrated that DasR is an important pleiotropic regulator for both secondary metabolism and morphological development in S. erythraea, providing new insights for the genetic engineering of S. erythraea with increased erythromycin production.

Eddy Correlation Flux Measurement System Handbook

Energy Technology Data Exchange (ETDEWEB)

Cook, D. R. [Argonne National Lab. (ANL), Argonne, IL (United States)

2016-01-01

The eddy correlation (ECOR) flux measurement system provides in situ, half-hour measurements of the surface turbulent fluxes of momentum, sensible heat, latent heat, and carbon dioxide (CO2) (and methane at one Southern Great Plains extended facility (SGP EF) and the North Slope of Alaska Central Facility (NSA CF). The fluxes are obtained with the eddy covariance technique, which involves correlation of the vertical wind component with the horizontal wind component, the air temperature, the water vapor density, and the CO2 concentration. The instruments used are: • a fast-response, three-dimensional (3D) wind sensor (sonic anemometer) to obtain the orthogonal wind components and the speed of sound (SOS) (used to derive the air temperature) • an open-path infrared gas analyzer (IRGA) to obtain the water vapor density and the CO2 concentration, and • an open-path infrared gas analyzer (IRGA) to obtain methane density and methane flux at one SGP EF and at the NSA CF. The ECOR systems are deployed at the locations where other methods for surface flux measurements (e.g., energy balance Bowen ratio [EBBR] systems) are difficult to employ, primarily at the north edge of a field of crops. A Surface Energy Balance System (SEBS) has been installed collocated with each deployed ECOR system in SGP, NSA, Tropical Western Pacific (TWP), ARM Mobile Facility 1 (AMF1), and ARM Mobile Facility 2 (AMF2). The surface energy balance system consists of upwelling and downwelling solar and infrared radiometers within one net radiometer, a wetness sensor, and soil measurements. The SEBS measurements allow the comparison of ECOR sensible and latent heat fluxes with the energy balance determined from the SEBS and provide information on wetting of the sensors for data quality purposes. The SEBS at one SGP and one NSA site also support upwelling and downwelling PAR measurements to qualify those two locations as Ameriflux sites.

The paper describes an innovative and advanced system for remaining life assessment of industrial high-temperature components developed at MPA Stuttgart, Germany and being currently introduced into the power plants in Germany and in several other countries. The system is a corporate memory system, essentially meaning that all the information/knowledge of a corporation (company, institute, etc.) should be maximally exploited in future activities of the company, with minimum changes in the existing structure of the data/information/knowledge already available. The system has two main aspects of practical implementation: (a) the organizational one, represented by MPA LifeTech, and (b) the software system one represented by the ``parent systems`` WISDOM and (WISDOM - WWW-based Intelligent System for Data and Documentation Management, ALIAS - The Advanced modular intelligent Life Assessment Software System).

Full Text Available Com as transformações no ambiente de negócios, os ativos intangíveis, potencialmente gerados pelo capital intelectual, ganharam importância. Este estudo tem como objetivo analisar e testar uma métrica alternativa de avaliação de desempenho que leva em conta os recursos humanos da empresa: o Retorno por Empregado (RE. Uma pesquisa exploratória foi realizada através do estudo de caso de três empresas com ações negociadas na BM&FBOVESPA no período 2006-2009. A partir das demonstrações financeiras das empresas, foram medidos seus desempenhos pelas métricas tradicionais, Retorno sobre Ativo e Retorno sobre Patrimônio Líquido, e pelo RE. O valor das ações de cada empresa foi usado como referência para criação de valor. Um estudo empírico complementar apontou que a correlação entre o RE e o preço das ações foi mais alta e significativa do que a correlação entre os indicadores tradicionais para a empresa mais intensiva em capital intelectual. Para as empresas intensivas em capital físico e em mão de obra, os indicadores de desempenho tradicionais apresentaram correlação mais alta. Sugere-se que a métrica alternativa seja um importante índice para empresas intensivas em capital intelectual. Reforça-se que tal medida de desempenho corporativo, que incorpora o efeito da força de trabalho intelectual, é uma contribuição importante à literatura sobre intangíveis.

Transferential Memory Spaces in Gisela Heidenreich’s Das endlose Jahr

Full Text Available What does it mean to be German after Hitler and National Socialism? Gisela Heidenreich’s memoir Das endlose Jahr: Die langsame Entdeckung der eigenen Biographie—ein Lebensborn Schicksal (The Endless Year: The Slow Discovery of My Own Biography—A Lebensborn Destiny, 2002, highlights the dependence on physical markers and monuments in understanding one’s place in history. Heidenreich discovers her origin as a Lebensborn child through family secrets, but it is not until she traverses the landscape of her past that she truly begins to understand her place within history. I argue that, along with family photographs and narratives, places play an integral role in the identity process through the metaphor of the palimpsest. In Heidenreich’s memoir, the German notion of Heimat reveals itself as a process, rather than a static and immovable space. Das endlose Jahr addresses the interplay between memory, places, and space through Heidenreich’s complex relationship with her mother, and her ambivalent sense of belonging through the palimpsest markers that remain. At its core, Das endlose Jahr is a memoir about the search for Heimat in all the wrong places.

Responsabilidade Social das empresas: a contraface da sociedade civil e da cidadania

2006-01-01

Full Text Available O artigo tem como objeto o estudo das mudanças que vêm ocorrendo nas relações entre Estado e sociedade civil e sua manifestação específica nas propostas articuladas em torno da responsabilidade social das empresas. Parte-se da hipótese de que estas práticas vêm contribuindo para a formação de consensos que fortalecem a hegemonia do capital na atualidade, mediante a redução do papel do Estado e o fortalecimento da esfera privada como setor de regulação social. Este cenário indica mudanças nas relações entre Estado e sociedade civil, uma vez que a responsabilidade social das empresas manifesta-se como uma nova proposta de sociabilidade e de resposta às expressões da questão social. Por fim, identifica-se que os serviços sociais oferecidos através da responsabilidade social fortalecem o campo do voluntariado, da solidariedade e das instituições do terceiro setor, precarizam o trabalho do Assistente Social com rebatimentos na esfera da cidadania e dos demais valores e princípios que sustentam o projeto ético-político da profissão

Full Text Available O artigo analisa se e como a agroecologia potencializa os papéis das mulheres rurais, em sua maioria agricultoras, dos municípios de Arroio do Padre e São Lourenço do Sul (RS. Através da realização de entrevistas em profundidade e da observação participante, o artigo analisa as percepções dessas mulheres a respeito das realidades por elas vivenciadas tanto no âmbito produtivo (lavoura como reprodutivo (doméstico. É importante destacar que, em Arroio do Padre, há um processo incipiente de “agroecologização”, ou seja, as unidades familiares encontram-se nos níveis iniciais da transição agroecológica. Já em São Lourenço do Sul, observou-se que essas mulheres atuam na agroecologia há mais de 40 anos. Estas distintas trajetórias conferem percepções de mundo diferenciadas entre os dois contextos sociais. Enquanto para as interlocutoras de Arroio do Padre a agroecologia pouco interfere em suas escolhas dentro e fora de casa, já para as entrevistadas de São Lourenço do Sul é essencial no repensar das relações estabelecidas no lar e no seu entorno, especialmente nos assuntos que tangem aos mercados e a sua valorização enquanto “agricultora”.

The photon tagging facility for the Crystal-Barrel/TAPS experiment at ELSA; Die Photonenmarkierungsanlage fuer das Crystal-Barrel/TAPS-Experiment an ELSA

Energy Technology Data Exchange (ETDEWEB)

Fornet-Ponse, Kathrin

2009-11-15

With the CBELASA/TAPS experiment in the framework of the SFB/TR 16 measurements of single- and double-polarization observables in the photoporoduction were performed. The energy of the high-energetic, polarized photon beams required for this, is determined by means of a so-called tagging system. In the framework of this thesis such a tagging system was constructed. It allows the energy tagging of the photons in an energy range from 0.021.E{sub 0} to 0.871.E{sub 0} with a time resolution of {sigma}=0.240 ns and an energy resolution from 0.1%.E{sub 0} to 0.4%.E{sub 0}. The reached time resolution allows to use the tagging system as time reference for the remaining experimental components. For the calculation of cross sections the knowledge of the photon flux at the experimental target is necessary. Thereby the photon definition probability P{sub {gamma}} plays a central role, which indicates, with which probability for a signal from the tagging system the corresponding photon in the {gamma} beam at the production target is present. It could be found a prescription for the determination of P{sub {gamma}}, which yields at tagging rates from 1 MHz to 10 MHz consistent results. A relative systematic error for P{sub {gamma}} was determined. Furthermore the effects of collimation and divergence of the photon beam on the number of the really in the experiment available photons and by this on the maximally reachable P{sub {gamma}} were extensively studied and experimental observations explained.

Die Energie der Photonen bestimmt sich aus der Differenz zwischen der Elektronenergie vor (E{sub 0}) und nach (E{sub e{sup -}}) dem Bremsstrahlungsprozess.

Lee, Minho; Yang, Hyun-Ik; Cho, Nahm-Gyoo

2016-01-01

In this paper, a new and simple optical technique to accurately measure the straightness errors of a linear stage is proposed. To improve the performance, including the measurement sensitivity and resolution of the measurement system, and to simultaneously measure two-dimensional straightness errors (2D straightness errors), an optical system was designed using a laser, a retro-reflector, a ball-lens, and a two-dimensional position sensitive detector (2D PSD). The characteristics of the measurement system were analytically and experimentally investigated. A prototype measurement system was manufactured based on the investigated results, and the performances of this system have been tested. The measuring performance of the system was easily improved by about 12 times using the proposed technique and it can be further improved. It is shown that the proposed technique can easily and effectively improve the performance of a conventional straightness measurement system based on the geometric optical method using a PSD.

Bei nerverhaltendem Vorgehen kann das Risiko der erektilen Dysfunktion gesenkt, aber nicht ausgeschlossen werden. Die präoperative Beratung der Patienten erfordert bei nerverhaltender Prostatektomie die Kenntnis der Faktoren, die Einfluss auf die postoperative Potenz haben. Patienten & Methoden: 110 Patienten antworteten 24 Monate nach radikaler perinealer nerverhaltender Prostatektomie auf einen per Post übermittelten Fragebogen. Die Patienten wurden, entsprechend dem Erection Hardness Score, nach der Rigidität ihrer Erektionen befragt. Überwiegend erfolgte der Nerverhalt unilateral (104/110. Verschiedene potenzielle Risikofaktoren (Alter, Qualität der präoperativen Erektion, Serum-PSA, Gleason-Score, Tumorvolumen, Prostatavolumen, adjuvante Strahlentherapie, ASA-Score, Chronic Disease Score [CDS], arterielle Hypertonie, Hypercholesterinämie, Diabetes mellitus, KHK, Nikotinkonsum wurden univariat mit der postoperativ erzielten Potenz korreliert. Multivariat wurden dann jene Parameter untersucht, die in der univariaten Analyse einen signifikanten (p ≤ 0,05 oder einen tendenziellen Zusammenhang (p ≤ 0,2 mit der postoperativen erektilen Funktion aufwiesen. Ergebnisse:Das Alter (p 0,001 und der ASAScore (p = 0,018 waren in der univariaten Analyse negative Prädiktoren der postoperativen Potenz.

Multi-scale biomedical systems: measurement challenges

International Nuclear Information System (INIS)

Summers, R

2016-01-01

Multi-scale biomedical systems are those that represent interactions in materials, sensors, and systems from a holistic perspective. It is possible to view such multi-scale activity using measurement of spatial scale or time scale, though in this paper only the former is considered. The biomedical application paradigm comprises interactions that range from quantum biological phenomena at scales of 10-12 for one individual to epidemiological studies of disease spread in populations that in a pandemic lead to measurement at a scale of 10+7. It is clear that there are measurement challenges at either end of this spatial scale, but those challenges that relate to the use of new technologies that deal with big data and health service delivery at the point of care are also considered. The measurement challenges lead to the use, in many cases, of model-based measurement and the adoption of virtual engineering. It is these measurement challenges that will be uncovered in this paper.

Machine vision system for measuring conifer seedling morphology

Science.gov (United States)

Rigney, Michael P.; Kranzler, Glenn A.

1995-01-01

A PC-based machine vision system providing rapid measurement of bare-root tree seedling morphological features has been designed. The system uses backlighting and a 2048-pixel line- scan camera to acquire images with transverse resolutions as high as 0.05 mm for precise measurement of stem diameter. Individual seedlings are manually loaded on a conveyor belt and inspected by the vision system in less than 0.25 seconds. Designed for quality control and morphological data acquisition by nursery personnel, the system provides a user-friendly, menu-driven graphical interface. The system automatically locates the seedling root collar and measures stem diameter, shoot height, sturdiness ratio, root mass length, projected shoot and root area, shoot-root area ratio, and percent fine roots. Sample statistics are computed for each measured feature. Measurements for each seedling may be stored for later analysis. Feature measurements may be compared with multi-class quality criteria to determine sample quality or to perform multi-class sorting. Statistical summary and classification reports may be printed to facilitate the communication of quality concerns with grading personnel. Tests were conducted at a commercial forest nursery to evaluate measurement precision. Four quality control personnel measured root collar diameter, stem height, and root mass length on each of 200 conifer seedlings. The same seedlings were inspected four times by the machine vision system. Machine stem diameter measurement precision was four times greater than that of manual measurements. Machine and manual measurements had comparable precision for shoot height and root mass length.

2008-01-01

While developing a measurement acquisition system to be used to retrofit aging aircraft with vehicle health monitoring capabilities, Langley Research Center developed an innovative wireless fluid-level measurement system. The NASA technology was of interest to Tidewater Sensors LLC, of Newport News, Virginia, because of its many advantages over conventional fuel management systems, including its ability to provide an accurate measurement of volume while a boat is experiencing any rocking motion due to waves or people moving about on the boat. These advantages led the company to license this novel fluid-level measurement system from NASA for marine applications.

2017-01-01

Full Text Available Measurement system analysis is carried out in order to determine if a capability to perform measurements in terms of product and process control is sufficient, indicating that the type I and the type II appraisal errors probability are acceptable. Statistical analyses for measurement system evaluation presented in the literature and the industrial manuals are not applicable for all complex and unusual applications. Therefore, the purpose of this study was to develop a robust statistical analysis method for measurement system variability analysis, in terms of product control scenario applied to one-sided tolerance. In the hereby presented study, the authors presented the theoretical principles of statistical techniques for measurement variations evaluation. Subsequently, the formula of gauge repeatability and reproducibility in terms of lower specification limit was proposed. The research hypothesis was tested using the statistical analysis.

Manuscritos freudianos inéditos: das ich und das es

Full Text Available Apresentamos aqui uma leitura crítica e comparada entre o rascunho e a forma final de O ego e o id, no momento em que nasce uma dissimetria entre o inconsciente reprimido e o material inconsciente que permanece não reconhecido. Partimos do capítulo "Os dois tipos de pulsão". O próprio Freud nos lembra que as questões aí levantadas retomam pensamentos iniciados em 1920. A partir da redefinição do Inconsciente e, mais tarde, com a reformulação da ideia de pulsão de morte, tais considerações permanecem mais perto da psicanálise que do texto Além.... Não obstante, o que denomina "nossa especulação" retorna nas conclusões do capítulo IV sobre o pressuposto da pulsão de morte. Com a irrupção do não-ligado, quais são os propósitos da pulsão de morte, em 1923, quando esta tem as mãos livres? Em 1924, constata que não-toda a pulsão está inscrita na representação. Intervém o silêncio da pulsão: essa fronteira, onde o id fala, o id goza e nada sabe.Freudian unpublished manuscripts: das Ich und das Es. This is a critical and comparative reading of the manuscripts of The Ego and the Id. We can read in this work a dissymmetry between the repressed unconscious and the material that remains unknown. We depart from chapter IV, "The two kinds of Drives". As Freud announces, the matters he displays resume thoughts from his writings of 1920. So, starting with the redefinition of Ucs and afterwards, with the reformulation of the idea of Todestrieb, they remain much closer to psychoanalysis than Beyond the pleasure principle. But what he calls, "our speculation" returns in the conclusions of chapter IV about the assumption of the Todestrieb. With the breaking through of the not bound: what are the purposes the Todestrieb serves, when, as he says in 1923, it has its hands free? In 1924 he confirms that not-all the drive is inscribed in the representation. The silence of the drive intervenes: this border, where id speaks, id enjoys

Breakdown of a negative-ion-based neutral beam injection (N-NBI) has caused noise trouble to several systems. The control circuit of a spectroscopic measurement system had not well worked because of the noise. The noise has been measured by an optical-fiber isolation system during operation of JT-60U. The amplitude and the frequency were 15-18 V and 15 MHz respectively. The transmission noise has been reduced by putting ferrite cores to all cables connecting with the control circuits. As a result, the trouble with the spectroscopic measurement system has completely been solved. Adding condensers and resistors to the circuit was not effective to reduce the noise. (author)

An Antenna Measurement System Based on Optical Feeding

the advantage of the system is demonstrated by measuring an ultra-wideband (UWB antenna both by the optical and electrical feeding systems and comparing with a calculated result. Ripples in radiation pattern due to the electrical feeding are successfully suppressed by the optical feeding. For example, in a radiation measurement on the azimuth plane at 3 GHz, ripple amplitude of 1.0 dB that appeared in the electrical feeding is reduced to 0.3 dB. In addition, a circularly polarized (CP antenna is successfully measured by the proposed system to show that the system is available not only for amplitude but also phase measurements.

Full Text Available Die Bevölkerungs- und Sozialstruktur Perus zeigt eine große Vielfalt, die sich erst aus einer Darstellung des Gewordenseins gesellschaftlicher Strukturen und den Verwobenheiten von soziopolitischen Prozessen in unterschiedlichen räumlichen und zeitlichen Dimensionen erschließt. Die bereits in der inkaischen Gesellschaft angelegten Hierarchien wurden in der Kolonialzeit nicht gebrochen, sondern von der spanischen Krone reproduziert und mit eigenen Machtstrukturen überlagert. Die Systeme der Feudalgesellschaft mit Leibeigenschaft und Sklaverei wirken bis heute nach. Die hierarchischen Beziehungen zwischen den unterschiedlichen ethno-sozialen Gruppen sind bis heute durch die verschiedensten Formen von Diskriminierung und Rassismen wirkmächtig, wenn es um den Zugang zu Land und Einkommen, Bildung und gesellschaftliche Anerkennung geht. Anhand zweier Fallstudien arbeitet der Beitrag gesellschaftliche Strukturierungsdynamiken als Ergebnis ungleicher Machtstrukturen und postkolonialer Verhältnisse exemplarisch heraus. Das erste Beispiel fokussiert auf den Callejón de Huaylas im Department Ancash und setzt sich mit denjenigen Diskriminierungsmechanismen auseinander, unter denen insbesondere die ländlich-andine Bevölkerung leidet. Das zweite Beispiel konzentriert sich auf die ehemalige deutsch-tirolische Siedlung Pozuzo im Department Pasco, in dem die europä-isch-stämmige Bevölkerung als privilegierte Bevölkerungsgruppe ihre migrantische Identität machtvoll rekonstruiert und damit andere Zuschreibungen oder Hybriditäten negiert. In beiden Fallstudien spielen ethnische Zuschreibungen als Differenzkategorie und Legitimierungsstrategie eine wichtige Rolle für die Herausbildung der aufgezeigten Ungleichheiten.

Driver's glance behaviour and secondary tasks; Einfluss von Nebenaufgaben auf das Fahrerblickverhalten

This paper contains a proposal for the evaluation of drivers' glance behavior, focussing on the influence of secondary tasks during driving. In general, an evaluation can only be achieved by regarding the quality of a task completion, which can be calculated by a comparison of a measured, actual value or behavior and a defined target value or behavior. Due to this definition, a target glance behavior is defined by so called continous and situational visual tasks. As opposed to continuous visual tasks, situational visual tasks contain a concrete description for a target glance behavior. A field trial (N=30) showed, that the subjects' glance behavior fulfilled most of the defined visual tasks when driving without a secondary task. Driving with secondary tasks leads to an increasing subjects' reliance on the correct driving of the other road users, shown by decreasing visual monitoring. (orig.) [German] Die vorliegende Untersuchung behandelt die Bewertung des Blickverhaltens von Fahrzeugfuehrern, wobei das Hauptaugenmerk auf dem Einfluss von Zusatzaufgaben liegt, die waehrend der Fahrt zu bearbeiten sind. Eine Bewertung ist immer eng mit dem Begriff der Qualitaet verknuepft, wobei ein Ist-Wert mit einem vorgegebenen Soll-Wert zu vergleichen ist. Nur wenn die Abweichung zwischen Soll und Ist gering ist, ist die Qualitaet hoch und die Bewertung somit positiv. Bei der Definition eines Soll-Blickverhaltens wird hier zwischen kontinuierlichen und situativen visuellen Aufgaben unterschieden. Letztere beinhalten konkrete Forderungen an das Fahrerblickverhalten in bestimmten Situationen, waehrend sich die Vorgabe eines Soll-Werts fuer kontinuierliche Aufgaben einer genauen Quantifizierung weitestgehend entzieht. Im Feldversuch (N=30) konnte gezeigt werden, dass bei den Fahrten ohne Zusatzaufgabenbearbeitung (Referenzbedingung) die definierten visuellen Aufgaben zum Grossteil erfuellt werden.

1992-01-01

An electronic system is presented for automatic mechanical tension measurement to test wire chambers. The developed system works in the tension range from 50 g to 300 g; this large working range is obtained by using a microcontroller that performs a digital control on the bridge of an oscillator containing the wire of which the tension has to be measured. The microcontroller automatically brings the system towards the oscillation condition and subsequently, measuring the frequency, it evaluates, displays and sends to a host computer the value of the mechanical tension of the wires. The system is precise and allows fast measurements. A description of the hardware and software design is given. (orig.)

Full Text Available In der vorliegenden Abhandlung wird die erwähnte Problematik in der slovenischen grammatischen -Überlieferung behandelt und mit interessanten Ergebnissen vor allem der tschechischen Sprachtheorie ergänzt, es wird der Terminus Prädikatsergänzung gegenüber dem Terminus Prädikatsattribut begründet; auf dieser Grundlage werden auch die bisher behandelten Arten von Prädikatsergänzungen mit neuen ergänzt. Dabei findet wenn nur möglich das einfache Transformationsverfahren Verwendung, das die Veranschaulichung der stufenweisen Determinierung durch das Prädikatsattribut ermöglicht. Das Material entstammt vorwiegend der Sprache der Kunst, der Grund dafür ist vor allem in der Tatsache zu suchen, daß in dieser Sprache dieser Form die Rolle eines natürlichen Kondensators zufällt, weshalb sie verhältnismäßig häufig vorkommt. Die Abhandlung befaßt sich eingehender auch mit dem Problem der Wortfolge und berührt auch die graphische Darstellung der bei der Prädikatsergänzung üblichen Pausen.

Full Text Available Este artigo apresenta um método para a medição do tempo de atravessamento e do inventário em processo em manufatura. A medição foi usada em processo de controle organizacional de manufatura, cuja variável controlada foi o tempo de atravessamento de ordens. Tal controle pode ser útil em estratégias de manufatura em que a competição é baseada no uso do tempo, a TBC (time-based competition. Apresentou-se o método de medição, que inclui elementos da teoria das filas, e considerações para a simplificação de arranjos produtivos de manufatura. Para testar e refinar o método, estudou-se um caso em manufatura calçadista. Foram coletados dados de remessas e obtido, por análise estatística e simulação computacional, o comportamento da variável aleatória tempo de atravessamento de remessas. Como a medição foi inferior ao objetivo de desempenho, partiu-se para o controle, fazendo um diagnóstico que apontou efeitos indesejáveis observados que foram endereçados por ações corretivas implementadas. Para verificar a eficácia das ações, nova coleta foi feita. Desta vez, o objetivo de desempenho das entregas foi atendido, fechando um ciclo de controle. Os resultados foram discutidos, chegando-se a conclusões e alternativas de continuidade.This paper presents a method for the measurement of the lead-time and work-in-process in manufacturing. The measurement was used in an organizational control process in manufacturing, in which the controlled variate was the order lead-time. This kind of control can be useful in manufacture strategies formulated to compete in TBC (time-based competition. We presented the method, who includes elements from the queuing theory, and concerns about simplifying complex manufacturing arrays, in order to facilitate the analysis. In order to test and refine the method, we studied a case in a footwear manufacture system. We collected data from orders and, by statistical techniques and computational

Full Text Available Resumo As competências para o trabalho têm sido tradicionalmente compreendidas como atributos de indivíduos; entretanto, estudos mais recentes tornam pertinente defender a sua ocorrência como atributos coletivos. O objetivo deste estudo foi demonstrar que competências individuais podem transformar-se em competências coletivas e, nesse nível, predizer o desempenho da equipe. A testagem empírica foi realizada em 51 aeródromos brasileiros, totalizando 106 equipes (entre 3 e 32 integrantes. Instrumentos respondidos pelos membros focaram nas competências enquanto os respondidos pelos lideres indagaram sobre o desempenho das equipes. Os resultados revelaram que as competências coletivas explicam aproximadamente 20% do desempenho das equipes. Disso depreende-se que as competências podem se manifestar como atributos coletivos que predizem resultados de equipes de trabalho.

Full Text Available Partindo do pressuposto de que as categorias classificatórias utilizadas na construção de "problemas sociais" influenciam nas formas de compreensão e gestão dos mesmos, o artigo analisa como o enfrentamento à violência sexual contra crianças a partir da noção de "pedofilia" e com o enfoque na pornografia infantil na internet produz um borramento das fronteiras entre atos e fantasias sexuais, produzindo um deslocamento da atenção política das desigualdades de poder para a ameaça das perversões. O material de análise é baseado em discussões legislativas realizadas no âmbito da Comissão Parlamentar de Inquérito da Pedofilia, do Senado Federal brasileiro, e em um dos inquéritos consultados durante pesquisa etnográfica na Polícia Federal. Por fim, são discutidos alguns dos efeitos da "cruzada antipedofilia".

To determine the level of residual inflammation [synovitis, bone marrow edema (BME), tenosynovitis, and total inflammation] quantified by hand magnetic resonance imaging (h-MRI) in patients with rheumatoid arthritis (RA) in remission according to 3 different definitions of clinical remission, and to compare these remission definitions. A cross-sectional study. To assess the level of residual MRI inflammation in remission, cutoff levels associated to remission and median scores of MRI residual inflammatory lesions were calculated. Data from an MRI register of patients with RA who have various levels of disease activity were used. These were used for the analyses: synovitis, BME according to the Rheumatoid Arthritis Magnetic Resonance Imaging Scoring system, tenosynovitis, total inflammation, and disease activity composite measures recorded at the time of MRI. Receiver-operating characteristic analysis was used to identify the best cutoffs associated with remission for each inflammatory lesion on h-MRI. Median values of each inflammatory lesion for each definition of remission were also calculated. A total of 388 h-MRI sets of patients with RA with different levels of disease activity, 130 in remission, were included. Cutoff values associated with remission according to the Simplified Disease Activity Index (SDAI) ≤ 3.3 and the Boolean American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) definitions for BME and tenosynovitis (1 and 3, respectively) were lower than BME and tenosynovitis (2 and 5, respectively) for the Disease Activity Score on 28 joints (DAS28) ≤ 2.6. Median scores for synovitis, BME, and total inflammation were also lower for the SDAI and Boolean ACR/EULAR remission criteria compared with DAS28. Patients with RA in remission according to the SDAI and Boolean ACR/EULAR definitions showed lower levels of MRI-detected residual inflammation compared with DAS28.

Design techniques for large scale linear measurement systems

Candy, J.V.

1979-03-01

Techniques to design measurement schemes for systems modeled by large scale linear time invariant systems, i.e., physical systems modeled by a large number (> 5) of ordinary differential equations, are described. The techniques are based on transforming the physical system model to a coordinate system facilitating the design and then transforming back to the original coordinates. An example of a three-stage, four-species, extraction column used in the reprocessing of spent nuclear fuel elements is presented. The basic ideas are briefly discussed in the case of noisy measurements. An example using a plutonium nitrate storage vessel (reprocessing) with measurement uncertainty is also presented

The Individual Bunch Measurement System (IBMS) allows the intensity of each bunch in an LHC batch to be the measured both in the PS to SPS transfer lines and in the SPS ring itself. The method is vased on measuring the peak and valley of the analogue signal supplied by a Fast Beam Current Transformer at a frequency of 40 MHz. A 12 bit acquisition system is required to obtain a 1% resolution for the intensity range of 5X10`9 to 1.7X10`11 protons per bunch, corresponding to the pilot and ultimate LHC bunch intensities. The acquisition selection and external trigger adjustment system is driven by the 200MHz RF, which is distributed using a single-mode fibre-optic link. A local oscilloscope, controlled via a GPIB interface, allows the remote adjustment of the timing signals. The low-level software consists of a real-time task and a communication server run on a VME Power PC, which is accessed using a graphical user interface. This paper describes the system as a whole and presents some recent uses and results fro...

Measurement and evaluation systems for NPP commissioning

Standard core monitoring and information systems are designed with an emphasis on normal operation of nuclear power plant. Their purpose is to provide necessary support for reactor operators and other operating personnel during the fuel cycle. After each fuel reloading, and to the larger extent during the plant commissioning, a variety of start-up tests need to be carried out and evaluated. Sampling periods, accuracy and communication delays of standard systems are not always suitable for test performance and evaluation. For technical and safety reasons, the access to standard monitoring and information systems is very limited. Non-Standard Measurement and Evaluation Systems are highly specialized devices designed with an emphasis on start-up tests performance and evaluation. They are capable of high frequency sampling, processing and communication of hundreds of technological signals with required accuracy and low communication delay. All technological signals needed for the test performance and evaluation are collected from various systems, concentrated in one system and fully accessible to a test leader, a reactor physicist or other users. In addition, Non-Standard Measurement and Evaluation Systems can perform other tasks like data storing and presentation, data distribution to other systems or external computers via network, reactivity calculations, etc. Structure of such systems can vary, but generally it is a mixture of two basic concepts: a mobile system and a stationary system. A basic description of hardware structure and software equipment of Non-Standard Measurement and Evaluation Systems is given in the paper (Authors)

The accident information and management system CAIRE for real time applications. Das Stoerfall-Leitsystem CAIRE fuer Echtzeitanwendungen

Remote monitoring systems have increased their importance as an inherent part of environmental surveillance installations in the FRG and in other countries. The existing systems in Germany are designed to cover both, routine operation and emergency situations. They provide site specific meteorological data, gross effluent dose rates, and dose rate measurements at on-site and approximately 30 off-site locations in the vicinity of a plant. Based on such telemetric surveillance networks an advanced automatic on-line system named CAIRE (Computer Aided Response to Emergencies) has been developed as a real time emergency response tool for nuclear facilities. This tool is designed to provide decision makers with most relevant radiation exposure data of the population at risk. CAIRE allows the continuous feed-back of current measurements of environmental impacts into diagnostic calculations for bringing measurements and calculations into best correspondence. This is the main advantage of CAIRE compared to conventional emergency systems and it results in both, a consistent actual interpretation of a bulk of single measurements of dose rates and/or activity concentrations, and a more realistic set of model parameters. Subsequently these parameters are used as input data for the evaluation of actual dose commitments and projections of them by means of real-time calculation. A second advantage is a more realistic assessment of the source term if in-plant dose rate measurements are not available due to emissions out of leckages, e.g. In such cases the assessment of the source term can be based an of-plant dose rate measurements located on the ground within a source distance between 200 and 300 m.
