Introduction: Age has been reported as a barrier to the use of Information Management and Technology (IM and T). Radiographers' confidence and ability in IM and T may be related to age and it is the aim of this research to investigate this relationship. Method: An online survey method gathered views from the radiographic population, between 31st August 2008 and 10th October 2008. The questionnaire encompassed IM and T ability, work based IM and T usage, personal IM and T usage, security and governance issues, education and training experience, the future and demographic details. For the purpose of this paper the first three sections and demographic section were considered. Results: Radiographers showed a good level of ability and confidence in the use of IM and T. Some general applications such as word processing showed a decreased confidence with age. Confidence in all radiography specific applications was scored highly although confidence in the use of Hospital Information Systems (HIS) and radiotherapy Treatment Planning Systems (TPS) showed the least confidence. Statistical analysis did not reveal a strong link between age and confidence in all applications. Discussion: While a link between age and confidence was not found in this study, frequency of use and training in IM and T require further investigation in relation to specific roles.

Full Text Available Accurate network traffic classification at early stage is very important for 5G network applications. During the last few years, researchers endeavored hard to propose effective machine learning model for classification of Internet traffic applications at early stage with few packets. Nevertheless, this essential problem still needs to be studied profoundly to find out effective packet number as well as effective machine learning (ML model. In this paper, we tried to solve the above-mentioned problem. For this purpose, five Internet traffic datasets are utilized. Initially, we extract packet size of 20 packets and then mutual information analysis is carried out to find out the mutual information of each packet on n flow type. Thereafter, we execute 10 well-known machine learning algorithms using crossover classification method. Two statistical analysis tests, Friedman and Wilcoxon pairwise tests, are applied for the experimental results. Moreover, we also apply the statistical tests for classifiers to find out effective ML classifier. Our experimental results show that 13–19 packets are the effective packet numbers for 5G IM WeChat application at early stage network traffic classification. We also find out effective ML classifier, where Random Forest ML classifier is effective classifier at early stage Internet traffic classification.

Detection of microbial volatile organic compounds (MVOC) by means of ion mobility spectroscopy (IMS); Detektion leicht fluechtiger organischer Verbindungen mikrobiellen Ursprungs (MVOC) mittels Ionenmobilitaetsspektrometrie (IMS)

Traces of microbial volatile organic compounds (MVOCs) can indicate the growth of moulds in the indoor air. The application of ion mobility spectrometry (IMS) is a very promising method for the detection of these MVOCs due to its high sensitivity. A mobile IMS device was tested to use this analytical-chemical method for in situ indoor air diagnostics. The first part of this work describes the test gas generation of 14 MVOCs in the laboratory. The test gases were produced by preparation of permeation procedures. Due to the MVOCs test gases IMS parameters like reduced mobility (K{sub 0}), relative drift time (t{sub rd}), the concentration dependency of MVOCs signals were determined and the limit of detection (LOD) was calculated. The LODs are in the range of 2 to 192 {mu}g m{sup -3} (1 to 51 ppb{sub V}). In the second part of this manuscript seven different mould species were cultivated on nutrient media and their MVOCs emissions were explored. It was found out, that the MVOCs emissions of moulds have a dependency of species and of their cultivation time. These results are confirmed by principal component analysis (PCA). The identification of these MVOCs was performed by test-related GC-MS analysis and approved these results. The MVOCs emissions were explored in the cultivation of mould mixtures on three different building materials. The IMS-results were interpreted chemo metrically by PCA. It was possible to find different emission patterns of cultivated moulds on building materials without an identification of the MVOCs inside the emission chamber. In 27 field trials of different indoor environments (rooms) the IMS was tested to detect MVOCs. In 59 % of the cases a positive correlation is determined between visible mould-infested rooms and the detected MVOCs by IMS. (orig.)

Precise outage analysis of mixed RF/unified-FSO DF relaying with HD and 2 IM-DD channel models

2017-07-20

This paper derives and analyzes the outage probability of mixed radio frequency (RF)/unified free space optical (FSO) dual-hop decode-and-forward (DF) relaying scheme, where heterodyne detection (HD) and intensity modulation-direct detection (IM-DD) are considered for FSO detection. In doing that, we correctly utilize, for the first time to the best of our knowledge, a precise channel capacity result for the IM-DD channel. Moreover, this is the first time that not only the (IM-DD input-independent) but also the (IM-DD cost-dependent) AWGN channel is considered in such system analysis. This work assumes that the first hop (RF link) follows Naka-gami-m fading, while the second hop (FSO link) follows Málaga (M) turbulence with pointing error. These fading and turbulence models include other ones (such as Rayleigh fading and Gamma-Gamma turbulence) as special cases, so our analysis can be considered as a generalized one from both RF and FSO fading models point of view. Additionally, the system outage probability is investigated asymptotically in high signal-to-noise ratio (SNR) regime, where a new non-reported diversity order and coding gain analysis are shown. Interestingly, we find that in the FSO hop, based on SNR, the HD or IM-DD cost-dependent results in a same diversity order which is twice the one of IM-DD input-independent. However, based on transmitted power all these FSO detectors result in a same diversity order. Furthermore, we offer simulation results which confirm the derived exact and asymptotic expressions.

Measurement techniques that provide molecular-level information are needed to elucidate the multiphase processes that produce secondary organic aerosol (SOA) species in the atmosphere. Here we demonstrate the application of ion mobility spectrometry-mass spectrometry (IMS-MS) to the simultaneous characterization of the elemental composition and molecular structures of organic species in the gas and particulate phases. Molecular ions of gas-phase organic species are measured online with IMS-MS after ionization with a custom-built nitrate chemical ionization (CI) source. This CI-IMS-MS technique is used to obtain time-resolved measurements (5 min) of highly oxidized organic molecules during the 2013 Southern Oxidant and Aerosol Study (SOAS) ambient field campaign in the forested SE US. The ambient IMS-MS signals are consistent with laboratory IMS-MS spectra obtained from single-component carboxylic acids and multicomponent mixtures of isoprene and monoterpene oxidation products. Mass-mobility correlations in the 2-D IMS-MS space provide a means of identifying ions with similar molecular structures within complex mass spectra and are used to separate and identify monoterpene oxidation products in the ambient data that are produced from different chemical pathways. Water-soluble organic carbon (WSOC) constituents of fine aerosol particles that are not resolvable with standard analytical separation methods, such as liquid chromatography (LC), are shown to be separable with IMS-MS coupled to an electrospray ionization (ESI) source. The capability to use ion mobility to differentiate between isomers is demonstrated for organosulfates derived from the reactive uptake of isomers of isoprene epoxydiols (IEPOX) onto wet acidic sulfate aerosol. Controlled fragmentation of precursor ions by collisionally induced dissociation (CID) in the transfer region between the IMS and the MS is used to validate MS peak assignments, elucidate structures of oligomers, and confirm the

Highlights: • Vapor pressures of [C 1 C 1 im][NTf 2 ] and [C 2 C 3 im][NTf 2 ] ionic liquids are reported. • [C 1 C 1 im][NTf 2 ] presents higher enthalpy and entropy of vaporization than expected. • The high volatility of [C 2 C 3 im][NTf 2 ] is a result from its asymmetric character. -- Abstract: Vapor pressures of 1,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide, ([C 1 C 1 im][NTf 2 ]) and 1-ethyl-3-propylimidazolium bis(trifluoromethylsulfonyl)imide, ([C 2 C 3 im][NTf 2 ]) ionic liquids were measured as a function of temperature using a Knudsen effusion apparatus combined with a quartz crystal microbalance. Enthalpies and entropies of vaporization were derived from the fitting of vapor pressure and temperature results to the Clarke and Glew equation. [C 1 C 1 im][NTf 2 ] presents a higher enthalpy and entropy of vaporization than the neighboring members of the series. The enthalpy of vaporization of [C 2 C 3 im][NTf 2 ] lies in between the asymmetric and symmetric ionic liquid series, reflecting a decrease in the electrostatic interactions due to a decrease of the charge accessibility between the ionic pairs when the methyl group is replaced by an ethyl group. The obtained higher volatility of [C 2 C 3 im][NTf 2 ] arises from its asymmetric character, leading to an higher entropic contribution that compensates the enthalpic penalty. The border conditions ([C 1 C 1 im][NTf 2 ], [C 2 C 1 im][NTf 2 ] and [C 2 C 2 im][NTf 2 ]), topology ([C 2 C 3 im][NTf 2 ]) and symmetry/asymmetry of the ILs effect were evaluated and rationalized based on a comparative analysis of the thermodynamic properties, enthalpies and entropies of vaporization

ImBuild: Impact of building energy efficiency programs

As part of measuring the impact of government programs on improving the energy efficiency of the Nation`s building stock, the Department of Energy Office of Building Technology, State and Community Programs (BTS) is interested in assessing the economic impacts of its portfolio of programs, specifically the potential impact on national employment and income. The special-purpose version of the IMPLAN model used in this study is called ImBuild. In comparison with simple economic multiplier approaches, such as Department of Commerce RIMS 2 system, ImBuild allows for more complete and automated analysis of the economic impacts of energy efficiency investments in buildings. ImBuild is also easier to use than existing macroeconomic simulation models. The authors conducted an analysis of three sample BTS energy programs: the residential generator-absorber heat exchange gas heat pump (GAX heat pump), the low power sulfur lamp (LPSL) in residential and commercial applications, and the Building America program. The GAX heat pump would address the market for the high-efficiency residential combined heating and cooling systems. The LPSL would replace some highly efficient fluorescent commercial lighting. Building America seeks to improve the energy efficiency of new factory-built, modular, manufactured, and small-volume, site-built homes through use of systems engineering concepts and early incorporation of new products and processes, and by increasing the demand for more energy-efficient homes. The authors analyze a scenario for market penetration of each of these technologies devised for BTS programs reported in the BTS GPRA Metrics Estimates, FY99 Budget Request, December 19, 1997. 46 figs., 4 tabs.

Midlatitude magnetometer chains during the IMS

International Nuclear Information System (INIS)

Mcpherron, R.L.

1982-01-01

The International Magnetospheric Study (IMS) is an international program to study global problems of magnetospheric dynamics. A key element of the U.S. participation in this program was the establishment of a ground magnetometer network. This network included a number of arrays at high and low latitudes. This report describes three chains established at midlatitudes, including the IMS Midlatitude Chain, the AFGL Magnetometer Network, and the Bell Lab Conjugate Array. Descriptions of the type of equipment, station locations, types of data display, and availability of data for each chain are presented in this report. A major problem of the data analysis phase of the IMS will be reducing selected subsets of these data to a common format. Currently, there are no plans to do this in a systematic manner

A critical analysis of Sorrell v. IMS Health, Inc.: Pandora's box at best.

2012-01-01

Sorrell v. IMS Health, Inc. ("IMS Health"), a remarkable health care case with resounding First Amendment and economic repercussions, features the clashing interests of the State of Vermont and aggressive free market players from the pharmaceutical and data mining industries in a constitutional battle over Free Speech. In 2007, Vermont enacted Act 80, The Confidentiality of Prescription Information Act, prohibiting the sale, disclosure, and use of pharmacy records. Together with two other data miners and PhRMA, an association of brand-name drug manufacturers, IMS Health successfully challenged the constitutionality of Act 80 on First Amendment grounds. This article examines the legal arguments of IMS Health and Act 80 and analyzes why IMS Health stands out for potentially challenging the traditional doctrine of commercial speech and the resulting legal implications. After reviewing the Supreme Court's reasoning, the article concludes that, although the Supreme Court reached the appropriate outcome, it did so by unjustifiably departing from the established legal doctrine of commercial speech and the American tradition of consumer protection. At best, IMS Health's reasoning opens a legal Pandora's Box potentially leading to an onset of new commercial speech challenges; at worst, it manufactured a Trojan Horse aimed at eroding the traditional regulatory safeguards that maintain a balance between the needs of consumers and corporations alike.

An in situ hybridization (ISH) study was performed on 2000 murine genes representing around 10% of the protein-coding genes present in the mouse genome using data generated by the EURExpress consortium. This study was carried out in 25 tissues of late gestation embryos (E14.5), with a special emphasis on the developing ear and on five distinct developing sensory organs, including the cochlea, the vestibular receptors, the sensory retina, the olfactory organ, and the vibrissae follicles. The results obtained from an analysis of more than 11,000 micrographs have been integrated in a newly developed knowledgebase, called ImAnno. In addition to managing the multilevel micrograph annotations performed by human experts, ImAnno provides public access to various integrated databases and tools. Thus, it facilitates the analysis of complex ISH gene expression patterns, as well as functional annotation and interaction of gene sets. It also provides direct links to human pathways and diseases. Hierarchical clustering of expression patterns in the 25 tissues revealed three main branches corresponding to tissues with common functions and/or embryonic origins. To illustrate the integrative power of ImAnno, we explored the expression, function and disease traits of the sensory epithelia of the five presumptive sensory organs. The study identified 623 genes (out of 2000) concomitantly expressed in the five embryonic epithelia, among which many (∼12%) were involved in human disorders. Finally, various multilevel interaction networks were characterized, highlighting differential functional enrichments of directly or indirectly interacting genes. These analyses exemplify an under-represention of "sensory" functions in the sensory gene set suggests that E14.5 is a pivotal stage between the developmental stage and the functional phase that will be fully reached only after birth.

Miniature GC-Minicell Ion Mobility Spectrometer (IMS) for In Situ Measurements in Astrobiology Planetary Missions

2006-01-01

Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or ionger mission life for stationary landers/laboratories. The miniCometary Ice and Dust Experiment (miniCIDEX), which combined Gas Chromatography (GC) with helium Ion Mobility Spectrometry (IMS), was capable of providing the wide range of analytical information required for Astrobiology missions. The IMS used here was based on the PCP model 111 IMS. A similar system, the Titan Ice and Dust Experiment (TIDE), was proposed as part of the Titan Orbiter Aerorover Mission (TOAM). Newer GC systems employing Micro Electro- Mechanical System (MEMS) based technology have greatly reduced both the size and resource requirements for space GCs. These smaller GCs, as well as the continuing miniaturization of Astrobiology analytical instruments in general, has highlighted the need for smaller, dry helium IMS systems. We describe here the development of a miniature, MEMS GC-IMS system (MEMS GC developed by Thorleaf Research Inc.), employing the MiniCell Ion Mobility Spectrometer (IMS), from Ion Applications Inc., developed through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA s Small Business Innovative Research (SBIR) Program.

Turbulence Heating ObserveR (THOR) is the first mission ever flown in space dedicated to plasma turbulence. Specifically, THOR will study how turbulent fluctuations at kinetic scales heat and accelerate particles in different turbulent environments within the near-Earth space. To achieve this goal, THOR payload is being designed to measure electromagnetic fields and particle distribution functions with unprecedented resolution and accuracy. Here we present the Ion Mass Spectrometer (IMS) instrument that will measure the full three-dimensional distribution functions of near-Earth main ion species (H+, He+, He++ and O+) at high time resolution (~ 150 ms for H+ , ~ 300 ms for He++) with energy resolution down to ~ 10% in the range 10 eV/q to 30 keV/q and angular resolution ~ 10°. Such high time resolution is achieved by mounting multiple sensors around the spacecraft body, in similar fashion to the MMS/FPI instrument. Each sensor combines a top-hat electrostatic analyzer with deflectors at the entrance together with a time-of-flight section to perform mass selection. IMS electronics includes a fast sweeping high voltage board that is required to make measurements at high cadence. Ion detection includes Micro Channel Plates (MCP) combined with Application-Specific Integrated Circuits (ASICs) for charge amplification, discrimination and time-to-digital conversion (TDC). IMS is being designed to address many of THOR science requirements, in particular ion heating and acceleration by turbulent fluctuations in foreshock, shock and magnetosheath regions. The IMS instrument is being designed and will be built by an international consortium of scientific institutes with main hardware contributions from France, USA, Japan and Germany.

[Application of Imaging Mass Spectrometry for Drug Discovery].

Imaging mass spectrometry (IMS) can reveal the distribution of biomolecules on tissue sections. In this process, the biomolecules are directly ionized within tissue sections using matrix-assisted laser desorption/ionization, and then their distribution is visualized by pseudo-color based on the relative signal intensity. The biomolecules, such as fatty acids, phospholipids, glycolipids, peptides, proteins, and neurotransmitters, have been analyzed at a spatial resolution of 5 μm. A special instrument for IMS analysis was developed by Shimadzu. The IMS analysis does not require the labeling of biomolecules and is capable of analyzing all the ionized biomolecules. Interest in this method has expanded to many research fields, including biology, agriculture, medicine, and pharmacology. The technique is especially relevant to the drug discovery process. As practiced currently, drug discovery is expensive and time consuming, requiring the preparation of probes for each drug and its metabolites, followed by systematic probe tracking in animal models. The IMS technique is expected to overcome these drawbacks by revealing the distribution of drugs and their metabolites using only a single analysis. In this symposium, I introduced the methodology and applications of IMS and discussed the feasibility of its application to drug discovery in the near future.

A SURVEY ON INDIAN EXPERIENCE ON INTEGRATED MANAGEMENT STANDARDS (IMS

Directory of Open Access Journals (Sweden)

2009-09-01

Full Text Available Adoption of management systems standards is a key issue in manufacturing industry in India. Following the global trend quality and environmental issues are gaining importance. However the number of ISO 14001 certified companies are much less in India as compared to ISO 9001. The integration of ISO 14001 with ISO 9001 may help companies to sustain competitive advantage and overcome disappointments with quality standards and in turn encourage companies to adopt good environmental practices. The aim of this research is to study the implementation of integrated management standards (IMS by the manufacturing organizations in India. The different aspects of integration and benefits of IMS implementation are analyzed. This r esearch is based on empirical study carried out in Indian manufacturing firms, involving the application of a questionnaire. This questionnaire was tested on 50 manufacturing companies in India. The study reveals that focus on stakeholders; top management commitment and training are critical success factors for implementation of IMS. The main benefits of integration are discussed. The small sample size is one of the major limitations of this study. The paper informs the managers in manufacturing organizations and practitioners of management system standards especially in developing countries about IMS and will enable them to adopt IMS in future so that those organizations may not implement multiple and overlapping MSS(Management System Standards.

Evaluation of the indenter modulus (IM) method in the international round robin test about the cable condition monitoring

International Nuclear Information System (INIS)

Kajimura, Yuusaku

2016-01-01

In order to ensure the reliability and safety of nuclear power plants, the diagnosis of cable aging is important. The Institute of Nuclear Safety System (INSS) has been developing the indenter modulus (IM) method for more than a dozen years. Its usefulness was demonstrated in the research project 'Assessment of cable aging for nuclear power plant' by the Japan Nuclear Energy Safety Organization in 2009. Furthermore, INSS participated in the IAEA Coordinated Research Project in 2013 to 2015, measuring and acquiring data of insulation materials of cables and cable jackets with insulation which had been never measured before by INSS. The main results are as follows. (1) The IM method is useful for new materials (for example, crosslinked polyolefins) which had never been measured before by INSS. (2) The IM method is also applicable to evaluation of cable jackets with insulation made of such materials as chlorosulfonated polyethylene. Therefore, the IM method is evaluated to be useful and applicable for most cable materials except those which have a high IM value initially and which have a small change in IM value during aging.

ImSET: Impact of Sector Energy Technologies

Energy Technology Data Exchange (ETDEWEB)

Roop, Joseph M.; Scott, Michael J.; Schultz, Robert W.

2005-07-19

This version of the Impact of Sector Energy Technologies (ImSET) model represents the ''next generation'' of the previously developed Visual Basic model (ImBUILD 2.0) that was developed in 2003 to estimate the macroeconomic impacts of energy-efficient technology in buildings. More specifically, a special-purpose version of the 1997 benchmark national Input-Output (I-O) model was designed specifically to estimate the national employment and income effects of the deployment of Office of Energy Efficiency and Renewable Energy (EERE) -developed energy-saving technologies. In comparison with the previous versions of the model, this version allows for more complete and automated analysis of the essential features of energy efficiency investments in buildings, industry, transportation, and the electric power sectors. This version also incorporates improvements in the treatment of operations and maintenance costs, and improves the treatment of financing of investment options. ImSET is also easier to use than extant macroeconomic simulation models and incorporates information developed by each of the EERE offices as part of the requirements of the Government Performance and Results Act.

The purpose of this work is to introduce the concepts of Δim-lacunary statistical convergence of order α and lacunary strongly (Δim,p )-convergence of order α. We establish some connections between lacunary strongly (Δim,p )-convergence of order α and Δim-lacunary statistical convergence of order α. It is shown that if a sequence is lacunary strongly (Δim,p )-summable of order α then it is Δim-lacunary statistically convergent of order α.

2013-11-01

The addition of ion mobility spectrometry to liquid chromatography-mass spectrometry experiments requires new, or updated, software tools to facilitate data processing. We introduce a command line software application LC-IMS-MS Feature Finder that searches for molecular ion signatures in multidimensional liquid chromatography-ion mobility spectrometry-mass spectrometry (LC-IMS-MS) data by clustering deisotoped peaks with similar monoisotopic mass, charge state, LC elution time and ion mobility drift time values. The software application includes an algorithm for detecting and quantifying co-eluting chemical species, including species that exist in multiple conformations that may have been separated in the IMS dimension. LC-IMS-MS Feature Finder is available as a command-line tool for download at http://omics.pnl.gov/software/LC-IMS-MS_Feature_Finder.php. The Microsoft.NET Framework 4.0 is required to run the software. All other dependencies are included with the software package. Usage of this software is limited to non-profit research to use (see README). rds@pnnl.gov. Supplementary data are available at Bioinformatics online.

Singular vector-based targeted observations of chemical constituents: description and first application of the EURAD-IM-SVA v1.0

Science.gov (United States)

Goris, N.; Elbern, H.

2015-12-01

Measurements of the large-dimensional chemical state of the atmosphere provide only sparse snapshots of the state of the system due to their typically insufficient temporal and spatial density. In order to optimize the measurement configurations despite those limitations, the present work describes the identification of sensitive states of the chemical system as optimal target areas for adaptive observations. For this purpose, the technique of singular vector analysis (SVA), which has proven effective for targeted observations in numerical weather prediction, is implemented in the EURAD-IM (EURopean Air pollution and Dispersion - Inverse Model) chemical transport model, yielding the EURAD-IM-SVA v1.0. Besides initial values, emissions are investigated as critical simulation controlling targeting variables. For both variants, singular vectors are applied to determine the optimal placement for observations and moreover to quantify which chemical compounds have to be observed with preference. Based on measurements of the airship based ZEPTER-2 campaign, the EURAD-IM-SVA v1.0 has been evaluated by conducting a comprehensive set of model runs involving different initial states and simulation lengths. For the sake of brevity, we concentrate our attention on the following chemical compounds, O3, NO, NO2, HCHO, CO, HONO, and OH, and focus on their influence on selected O3 profiles. Our analysis shows that the optimal placement for observations of chemical species is not entirely determined by mere transport and mixing processes. Rather, a combination of initial chemical concentrations, chemical conversions, and meteorological processes determines the influence of chemical compounds and regions. We furthermore demonstrate that the optimal placement of observations of emission strengths is highly dependent on the location of emission sources and that the benefit of including emissions as target variables outperforms the value of initial value optimization with growing

A two-stage extraction procedure for insensitive munition (IM) explosive compounds in soils.

Science.gov (United States)

Felt, Deborah; Gurtowski, Luke; Nestler, Catherine C; Johnson, Jared; Larson, Steven

2016-12-01

The Department of Defense (DoD) is developing a new category of insensitive munitions (IMs) that are more resistant to detonation or promulgation from external stimuli than traditional munition formulations. The new explosive constituent compounds are 2,4-dinitroanisole (DNAN), nitroguanidine (NQ), and nitrotriazolone (NTO). The production and use of IM formulations may result in interaction of IM component compounds with soil. The chemical properties of these IM compounds present unique challenges for extraction from environmental matrices such as soil. A two-stage extraction procedure was developed and tested using several soil types amended with known concentrations of IM compounds. This procedure incorporates both an acidified phase and an organic phase to account for the chemical properties of the IM compounds. The method detection limits (MDLs) for all IM compounds in all soil types were regulatory risk-based Regional Screening Level (RSL) criteria for soil proposed by the U.S. Army Public Health Center. At defined environmentally relevant concentrations, the average recovery of each IM compound in each soil type was consistent and greater than 85%. The two-stage extraction method decreased the influence of soil composition on IM compound recovery. UV analysis of NTO established an isosbestic point based on varied pH at a detection wavelength of 341 nm. The two-stage soil extraction method is equally effective for traditional munition compounds, a potentially important point when examining soils exposed to both traditional and insensitive munitions.

ImNet: a fiber optic network with multistar topology for high-speed data transmission

Science.gov (United States)

Vossebuerger, F.; Keizers, Andreas; Soederman, N.; Meyer-Ebrecht, Dietrich

1993-10-01

ImNet is a fiber-optic local area network, which has been developed for high speed image communication in Picture Archiving and Communication Systems (PACS). A comprehensive analysis of image communication requirements in hospitals led to the conclusion that there is a need for networks which are optimized for the transmission of large datafiles. ImNet is optimized for this application in contrast to current-state LANs. ImNet consists of two elements: a link module and a switch module. The point-to-point link module can be up to 4 km by using fiber optic cable. For short distances up to 100 m a cheaper module using shielded twisted pair cable is available. The link module works bi-directionally and handles all protocols up to OSI-Level 3. The data rate per link is up to 140 MBit/s (clock rate 175 MHz). The switch module consists of the control unit and the cross-point-switch array. The array has up to fourteen interfaces for link modules. Up to fourteen data transfers each with a maximal transfer rate of 400 MBit/s can be handled at the same time. Thereby the maximal throughput of a switch module is 5.6 GBit/s. Out of these modules a multi-star network can be built i.e., an arbitrary tree structure of stars. This topology allows multiple transmissions at the same time as long as they do not require identical links. Therefore the overall throughput of ImNet can be a multiple of the datarate per link.

In this study, using the generalized difference operator Δim and a sequence λ = (λn) which is a non-decreasing sequence of positive numbers tending to ∞ such that λn+1 ≤ λn+1, λ1 = 1, we introduce the concepts of λ (Δim) -statistical convergence of order α (α ∈ (0, 1]) and strong λ (Δim) -Cesàro summablility of order α (α > 0). We establish some connections between λ (Δim) -statistical convergence of order α and strong λ (Δim) -Cesàro summablility of order α. It is shown that if a sequence is strongly λ (Δim) -Cesàro summable of order α, then it is λ (Δim) -statistically convergent of order β in case 0 < α ≤ β ≤ 1.

Marco Alessi

2015-12-01

Full Text Available Novel ideas are the key ingredients for innovation processes, and Idea Management System (IMS plays a prominent role in managing captured ideas from external stakeholders and internal actors within an Open Innovation process. By considering a specific case study, Lecce-Italy, we have designed and implemented a collaborative environment, which provides an ideal platform for government, citizens, etc. to share ideas and co-create the value of innovative public services in Lecce. In this study the application of IMS with six main steps, including: idea generation, idea improvement, idea selection, refinement, idea implementation, and monitoring, shows that this, remarkably, helps service providers to exploit the intellectual capital and initiatives of the regional stakeholders and citizens and assist service providers to stay in line with the needs of society. Moreover, we have developed two support tools to foster collaboration and transparency: sentiment analysis tool and gamification application.

iMS2Flux – a high–throughput processing tool for stable isotope labeled mass spectrometric data used for metabolic flux analysis

Directory of Open Access Journals (Sweden)

Poskar C Hart

2012-11-01

Full Text Available Abstract Background Metabolic flux analysis has become an established method in systems biology and functional genomics. The most common approach for determining intracellular metabolic fluxes is to utilize mass spectrometry in combination with stable isotope labeling experiments. However, before the mass spectrometric data can be used it has to be corrected for biases caused by naturally occurring stable isotopes, by the analytical technique(s employed, or by the biological sample itself. Finally the MS data and the labeling information it contains have to be assembled into a data format usable by flux analysis software (of which several dedicated packages exist. Currently the processing of mass spectrometric data is time-consuming and error-prone requiring peak by peak cut-and-paste analysis and manual curation. In order to facilitate high-throughput metabolic flux analysis, the automation of multiple steps in the analytical workflow is necessary. Results Here we describe iMS2Flux, software developed to automate, standardize and connect the data flow between mass spectrometric measurements and flux analysis programs. This tool streamlines the transfer of data from extraction via correction tools to 13C-Flux software by processing MS data from stable isotope labeling experiments. It allows the correction of large and heterogeneous MS datasets for the presence of naturally occurring stable isotopes, initial biomass and several mass spectrometry effects. Before and after data correction, several checks can be performed to ensure accurate data. The corrected data may be returned in a variety of formats including those used by metabolic flux analysis software such as 13CFLUX, OpenFLUX and 13CFLUX2. Conclusion iMS2Flux is a versatile, easy to use tool for the automated processing of mass spectrometric data containing isotope labeling information. It represents the core framework for a standardized workflow and data processing. Due to its flexibility

2016-04-01

This paper describes an information repository to support bridge monitoring applications on a cloud computing platform. Bridge monitoring, with instrumentation of sensors in particular, collects significant amount of data. In addition to sensor data, a wide variety of information such as bridge geometry, analysis model and sensor description need to be stored. Data management plays an important role to facilitate data utilization and data sharing. While bridge information modeling (BrIM) technologies and standards have been proposed and they provide a means to enable integration and facilitate interoperability, current BrIM standards support mostly the information about bridge geometry. In this study, we extend the BrIM schema to include analysis models and sensor information. Specifically, using the OpenBrIM standards as the base, we draw on CSI Bridge, a commercial software widely used for bridge analysis and design, and SensorML, a standard schema for sensor definition, to define the data entities necessary for bridge monitoring applications. NoSQL database systems are employed for data repository. Cloud service infrastructure is deployed to enhance scalability, flexibility and accessibility of the data management system. The data model and systems are tested using the bridge model and the sensor data collected at the Telegraph Road Bridge, Monroe, Michigan.

Power-efficient method for IM-DD optical transmission of multiple OFDM signals.

Effenberger, Frank; Liu, Xiang

2015-05-18

We propose a power-efficient method for transmitting multiple frequency-division multiplexed (FDM) orthogonal frequency-division multiplexing (OFDM) signals in intensity-modulation direct-detection (IM-DD) optical systems. This method is based on quadratic soft clipping in combination with odd-only channel mapping. We show, both analytically and experimentally, that the proposed approach is capable of improving the power efficiency by about 3 dB as compared to conventional FDM OFDM signals under practical bias conditions, making it a viable solution in applications such as optical fiber-wireless integrated systems where both IM-DD optical transmission and OFDM signaling are important.

A novel diamino/dicationic polyamide f-Im(*)PyIm (5) that contains an orthogonally positioned aminopropyl chain on an imidazole (Im(*)) moiety was designed to target 5'-ACGCGT-3'. The DNA binding properties of the diamino polyamide 5, determined by CD, ΔT(M), DNase I footprinting, SPR, and ITC studies, were compared with those of its monoamino/monocationic counterpart f-ImPyIm (1) and its diamino/dicationic isomer f-ImPy(*)Im (2), which has the aminopropyl group attached to the central pyrrole unit (Py(*)). The results gave evidence for the minor groove binding and selectivity of polyamide 5 for the cognate sequence 5'-ACGCGT-3', and with strong affinity (K(eq)=2.3×10(7) M(-1)). However, the binding affinities varied according to the order: f-ImPy(*)Im (2)>f-ImPyIm (1)≥f-Im(*)PyIm (5) confirming that the second amino group can improve affinity, but its position within the polyamide can affect affinity.

Linda D Stewart

Full Text Available Immunomagnetic separation (IMS can selectively isolate and concentrate Mycobacterium bovis cells from lymph node tissue to facilitate subsequent detection by PCR (IMS-PCR or culture (IMS-MGIT. This study describes application of these novel IMS-based methods to test for M. bovis in a survey of 280 bovine lymph nodes (206 visibly lesioned (VL, 74 non-visibly lesioned (NVL collected at slaughter as part of the Northern Ireland bovine TB eradication programme. Their performance was evaluated relative to culture. Overall, 174 (62.1% lymph node samples tested positive by culture, 162 (57.8% by IMS-PCR (targeting IS6110, and 191 (68.2% by IMS-MGIT culture. Twelve (6.9% of the 174 culture positive lymph node samples were not detected by either of the IMS-based methods. However, an additional 79 M. bovis positive lymph node samples (27 (13.1% VL and 52 (70.3% NVL were detected by the IMS-based methods and not by culture. When low numbers of viable M. bovis are present in lymph nodes (e.g. in NVLs of skin test reactor cattle decontamination prior to culture may adversely affect viability, leading to false negative culture results. In contrast, IMS specifically captures whole M. bovis cells (live, dead or potentially dormant which are not subject to any deleterious treatment before detection by PCR or MGIT culture. During this study only 2.7% of NVL lymph nodes tested culture positive, whereas 70.3% of the same samples tested M. bovis positive by the IMS-based tests. Results clearly demonstrate that not only are the IMS-based methods more rapid but they have greater detection sensitivity than the culture approach currently used for the detection of M. bovis infection in cattle. Adoption of the IMS-based methods for lymph node testing would have the potential to improve M. bovis detection in clinical samples.

Full Text Available Results : 1. The most important concept of IMS is chronic pain illness that may develop into hypersensitivity of the nerves, i.e., neuropathy. 2. Muscle shortening may be triggered by stress, including emotional, physical, external, and internal factors. 3. Muscle shortening increases mechanical tension on the muscles as well as inducing abrasion of the tissues by stretching ligament, tendon, cartilage, bone, and etc. 4. Pain from neuropathy is normally manifested on musculoskeletal system and spasm or shortening play as the central axis of this pain. 5. Neuropathy often appears at the nerve root level and the most important decisive factor of radiculopathy is muscle shortening. 6. Spondylosis is the most common cause of radiculopathy. 7. The most significant treatment principle of IMS is to relieve muscle shortening and remove stimulating determinant from the vertebrae. 8. Dry needling is quite effective for treating various pain caused by muscle shortening.

Cytoprotection of human endothelial cells against oxidative stress by 1-[2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl]imidazole (CDDO-Im): application of systems biology to understand the mechanism of action.

Science.gov (United States)

Wang, Xinyu; Bynum, James A; Stavchansky, Solomon; Bowman, Phillip D

2014-07-05

Cellular damage from oxidative stress, in particular following ischemic injury, occurs during heart attack, stroke, or traumatic injury, and is potentially reducible with appropriate drug treatment. We previously reported that caffeic acid phenethyl ester (CAPE), a plant-derived polyphenolic compound, protected human umbilical vein endothelial cells (HUVEC) from menadione-induced oxidative stress and that this cytoprotective effect was correlated with the capacity to induce heme oxygenase-1 (HMOX1) and its protein product, a phase II cytoprotective enzyme. To further improve this cytoprotective effect, we studied a synthetic triterpenoid, 1-[2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl]imidazole (CDDO-Im), which is known as a potent phase II enzyme inducer with antitumor and anti-inflammatory activities, and compared it to CAPE. CDDO-Im at 200nM provided more protection to HUVEC against oxidative stress than 20μM CAPE. We explored the mechanism of CDDO-Im cytoprotection with gene expression profiling and pathway analysis and compared to that of CAPE. In addition to potent up-regulation of HMOX1, heat shock proteins (HSP) were also found to be highly induced by CDDO-Im in HUVEC. Pathway analysis results showed that transcription factor Nrf2-mediated oxidative stress response was among the top canonical pathways commonly activated by both CDDO-Im and CAPE. Compared to CAPE, CDDO-Im up-regulated more HSP and some of them to a much higher extent. In addition, CDDO-Im treatment affected Nrf2 pathway more significantly. These findings may provide an explanation why CDDO-Im is a more potent cytoprotectant than CAPE against oxidative stress in HUVEC. Copyright © 2014 Elsevier B.V. All rights reserved.

Background and Purpose We assessed the effect of endovascular treatment in acute ischemic stroke patients with severe neurological deficit (NIHSS ≥20) following a pre-specified analysis plan. Methods The pooled analysis of the IMS III and MR CLEAN trial included participants with an NIHSS ≥20 prior to intravenous (IV) t-PA treatment (IMS III) or randomization (MR CLEAN) who were treated with IV t-PA ≤ 3 hours of stroke onset. Our hypothesis was that participants with severe stroke randomized to endovascular therapy following IV t-PA would have improved 90-day outcome (distribution of modified Rankin scale [mRS] scores), as compared to those who received IV t-PA alone. Results Among 342 participants in the pooled analysis (194 from IMS III, 148 from MR CLEAN), an ordinal logistic regression model showed that the endovascular group had superior 90-day outcome compared to the IV t-PA group (adjusted odds ratio [aOR] 1.78; 95% confidence interval [CI] 1.20-2.66). In the logistic regression model of the dichotomous outcome (mRS 0-2, or ‘functional independence’), the endovascular group had superior outcomes (aOR 1.97; 95% CI 1.09-3.56). Functional independence (mRS ≤2) at 90 days was 25% in the endovascular group as compared to 14% in the IV t-PA group. Conclusions Endovascular therapy following IV t-PA within 3 hours of symptom onset improves functional outcome at 90 days after severe ischemic stroke. PMID:26486865

Little is known about the associations of previous standardized examination scores with scores on subsequent standardized examinations used to assess medical knowledge in internal medicine residencies. To examine associations of previous standardized test scores on subsequent standardized test scores. Retrospective cohort study. One hundred ninety-five internal medicine residents. Bivariate associations of United States Medical Licensing Examination (USMLE) Steps and Internal Medicine In-Training Examination (IM-ITE) scores were determined. Random effects analysis adjusting for repeated administrations of the IM-ITE and other variables known or hypothesized to affect IM-ITE score allowed for discrimination of associations of individual USMLE Step scores on IM-ITE scores. In bivariate associations, USMLE scores explained 17% to 27% of the variance in IME-ITE scores, and previous IM-ITE scores explained 66% of the variance in subsequent IM-ITE scores. Regression coefficients (95% CI) for adjusted associations of each USMLE Step with IM-ITE scores were USMLE-1 0.19 (0.12, 0.27), USMLE-2 0.23 (0.17, 0.30), and USMLE-3 0.19 (0.09, 0.29). No single USMLE Step is more strongly associated with IM-ITE scores than the others. Because previous IM-ITE scores are strongly associated with subsequent IM-ITE scores, appropriate modeling, such as random effects methods, should be used to account for previous IM-ITE administrations in studies for which IM-ITE score is an outcome.

A New IMS Based Inter-working Solution

Science.gov (United States)

Zhu, Zhongwen; Brunner, Richard

With the evolution of third generation network, more and more multimedia services are developed and deployed. Any new service to be deployed in IMS network is required to inter-work with existing Internet communities or legacy terminal users in order to appreciate the end users, who are the main drivers for the service to succeed. The challenge for Inter-working between IMS (IP Multimedia Subsystem) and non-IMS network is “how to handle recipient’s address”. This is because each network has its own routable address schema. For instance, the address for Google Talk user is xmpp:xyz@google.com, which is un-routable in IMS network. Hereafter a new Inter-working (IW) solution between IMS and non-IMS network is proposed for multimedia services that include Instant Messaging, Chat, and File transfer, etc. It is an end-to-end solution built on IMS infrastructure. The Public Service Identity (PSI) defined in 3GPP standard (3rd Generation Partnership Project) is used to allow terminal clients to allocate this IW service. When sending the SIP (Session Initial Protocol) request out for multimedia services, the terminal includes the recipient’s address in the payload instead of the “Request-URI” header. In the network, the proposed solution provides the mapping rules between different networks in MM-IW (Multimedia IW). The detailed technical description and the corresponding use cases are present. The comparison with other alternatives is made. The benefits of the proposed solution are highlighted.

The development of sensitive and selective biosensing techniques is of great interest for clinical diagnostics. Here, we describe the development and application of a surface enhanced Raman scattering (SERS) sensing technology, referred to as "inverse Molecular Sentinel (iMS)" nanoprobes, for the detection of nucleic acid biomarkers in biological samples. This iMS nanoprobe involves the use of plasmonic-active nanostars as the sensing platform for a homogenous assay for multiplexed detection of nucleic acid biomarkers, including DNA, RNA and microRNA (miRNA). The "OFF-to-ON" signal switch is based on a non-enzymatic strand-displacement process and the conformational change of stem-loop (hairpin) oligonucleotide probes upon target binding. Here, we demonstrate the development of iMS nanoprobes for the detection of DNA sequences as well as a modified design of the nanoprobe for the detection of short (22-nt) microRNA sequences. The application of iMS nanoprobes to detect miRNAs in real biological samples was performed with total small RNA extracted from breast cancer cell lines. The multiplex capability of the iMS technique was demonstrated using a mixture of the two differently labeled nanoprobes to detect miR-21 and miR-34a miRNA biomarkers for breast cancer. The results of this study demonstrate the feasibility of applying the iMS technique for multiplexed detection of nucleic acid biomarkers, including short miRNAs molecules.

Liquid chromatography/mass spectrometry is widely used for studying sequence determination and modification analysis of small RNAs. However, the efficiency of liquid chromatography-based separation of intact small RNA species is insufficient, since the physiochemical properties among small RNAs are very similar. In this study, we focused on ion mobility-mass spectrometry (IM-MS), which is a gas-phase separation technique coupled with mass spectrometry; we have evaluated the utility of IM-MS for microRNA (miRNA) analysis. A multiply charged deprotonated ion derived from an 18-24-nt-long miRNA was formed by electrospray ionization, and then the time, called the "drift time", taken by each ion to migrate through a buffer gas was measured. Each multivalent ion was temporally separated on the basis of the charge state and structural formation; 3 types of unique mass-mobility correlation patterns (i.e., chainlike-form, hairpin-form, and dimer-form) were present on the two-dimensional mobility-mass spectrum. Moreover, we found that the ion size (sequence length) and the secondary structures of the small RNAs strongly contributed to the IM-MS-based separation, although solvent conditions such as pH had no effect. Therefore, sequence isomers could also be discerned by the selection of each specific charged ion, i.e., the 6(-) charged ion reflected a majority among chainlike-, hairpin-, and other structures. We concluded that the IM-MS provides additional capability for separation; thus, this analytical method will be a powerful tool for comprehensive small RNA analysis. Copyright © 2012.

The International Monitoring System (IMS) is to consist of 321 monitoring facilities, composed of four different technologies with a variety of designs and equipment types, deployed in a range of environments around the globe. The International Monitoring System is conceived to operate in perpetuity through maintenance, replacement and recapitalization of IMS facilities' infrastructure and equipment when the end of service life is reached [CTBT/PTS/INF.1163]. Life Cycle techniques and modellization are being used by the PTS to plan and forecast life cycle sustainment requirements of IMS facilities. Through historical data analysis, Engineering inputs and Feedback from experienced Station Operators, the PTS currently works towards increasing the level of confidence on these forecasts and sustainment requirements planning. Continued validation, feedback and improvement of source data from scientific community and experienced users is sought and essential in order to ensure limited effect on data availability and optimal costs (human and financial).

Broken Bar Fault Detection in IM Operating Under No-Load Condition

Directory of Open Access Journals (Sweden)

RELJIC, D.

2016-11-01

Full Text Available This paper presents a novel method for broken rotor bar detection in a squirrel-cage induction motor (IM. The proposed method applies a single-phase AC voltage as a test signal on motor terminals, resulting in a stator backward-rotating magnetic field. The field ultimately causes additional current components in the stator windings whose magnitudes depend on the broken bar fault severity, even if the motor is unloaded. This allows robust broken bar fault detection based only on standard motor current signature analysis (MCSA technique. The proposed fault detection method is at first verified via simulations, using an IM model based on finite element analysis (FEA and multiple coupled circuit approach (MCCA. The subsequent experimental investigations have shown good agreement with both theoretical predictions and simulation results.

Low temperature stress adversely affects plant growth, development, and crop productivity. Analysis of the function of genes in the response of plants to low temperature stress is essential for understanding the mechanism of chilling and freezing tolerance. In this study, PsCor413im1, a novel cold-regulated gene isolated from Phlox subulata, was transferred to Arabidopsis to investigate its function under low temperature stress. Real-time quantitative PCR analysis revealed that PsCor413im1 expression was induced by cold and abscisic acid. Subcellular localization revealed that PsCor413im1-GFP fusion protein was localized to the periphery of the chloroplast, consistent with the localization of chloroplast inner membrane protein AtCor413im1, indicating that PsCor413im1 is a chloroplast membrane protein. Furthermore, the N-terminal of PsCor413im1 was determined to be necessary for its localization. Compared to the wild-type plants, transgenic plants showed higher germination and survival rates under cold and freezing stress. Moreover, the expression of AtCor15 in transgenic plants was higher than that in the wild-type plants under cold stress. Taken together, our results suggest that the overexpression of PsCor413im1 enhances low temperature tolerance in Arabidopsis. Copyright © 2017 Elsevier Inc. All rights reserved.

Non-target analysis has become an important tool in the field of water analysis since a broad variety of pollutants from different sources are released to the water cycle. For identification of compounds in such complex samples, liquid chromatography coupled to high resolution mass spectrometry are often used. The introduction of ion mobility spectrometry provides an additional separation dimension and allows determining collision cross sections (CCS) of the analytes as a further physicochemical constant supporting the identification. A CCS database with more than 500 standard substances including drug-like compounds and pesticides was used for CCS data base search in this work. A non-target analysis of a wastewater sample was initially performed with high performance liquid chromatography (HPLC) coupled to an ion mobility-quadrupole-time of flight mass spectrometer (IM-qTOF-MS). A database search including exact mass (±5 ppm) and CCS (±1 %) delivered 22 different compounds. Furthermore, the same sample was analyzed with a two-dimensional LC method, called LC+LC, developed in our group for the coupling to IM-qTOF-MS. This four dimensional separation platform revealed 53 different compounds, identified over exact mass and CCS, in the examined wastewater sample. It is demonstrated that the CCS database can also help to distinguish between isobaric structures exemplified for cyclophosphamide and ifosfamide.

In this work the first rotor of a counterrotating shrouded propfan has been investigated to enable an overview of the complex rotor exit flow, basing on unsteady measurements. For this purpose the accuracy of the high speed probe technique has been improved. In combination with the 3D-Laser-2-Fokus system measurements were carried out in order to show the turbulent behaviour of the rotor exit flow. Though the turbulence models are presently not sufficiently developed, comparisons with results of numerical flow simulations support to interpret some wake details. A further focal point of this work is to determine the local losses for quantifying the isentropic efficiency and the pressure loss distribution. These investigations on the compressor`s exit flow can be used as a base for code validation and as design data for the next stage. (orig.). 95 figs., 2 tabs., 60 refs. [Deutsch] In dieser Arbeit wurde der erste Rotor eines gegenlaeufigen ummantelten Propfans experimentell untersucht.

Mit diesen Messungen wird das turbulente Verhalten der Nachlaufstroemung aufgezeigt. Vergleiche mit Ergebnissen aus Rechnungen helfen trotz der derzeit noch nicht weit genug entwickelten Turbulenzmodelle, Stroemungsphaenomene im Nachlauf zu erklaeren. Ein weiterer Schwerpunkt der Arbeit liegt in der Bestimmung der lokalen Verlustleistung, um den lokalen Wirkungsgrad und damit die lokalen Verluste im Verdichteraustritt quantifizieren zu koennen.

Matrix-assisted laser desorption/ionization (MALDI)-imaging mass spectrometry (IMS) enables visualization of the distribution of a range of biomolecules by integrating biochemical information from mass spectrometry with positional information from microscopy. IMS identifies a target molecule. In addition, IMS enables global analysis of biomolecules containing unknown molecules by detecting the ratio of the molecular weight to electric charge without any target, which makes it possible to identify novel molecules. IMS generates data on the distribution of lipids and small molecules in tissues, which is difficult to visualize with either conventional counter-staining or immunohistochemistry. In this review, we firstly introduce the principle of imaging mass spectrometry and recent advances in the sample preparation method. Secondly, we present findings regarding biological samples, especially pathological ones. Finally, we discuss the limitations and problems of the IMS technique and clinical application, such as in drug development.

The report is intended as information for the German Bundestag and Bundesrat as well as for the general population interested in issues of radiological protection. The information presented in the report shows that in 1996, the radiation dose to the population was low and amounted to an average of 4 millisievert (mSv), with 60% contributed by natural radiation sources, and 40% by artificial sources. The major natural source was the radioactive gas radon in buildings. Anthropogenic radiation exposure almost exclusively resulted from application of radioactive substances and ionizing radiation in the medical field, for diagnostic purposes. There still is a potential for reducing radiation doses due to these applications. In the reporting year, there were 340 000 persons occupationally exposed to ionizing radiation. Only 15% of these received a dose different from zero, the average dose was 1.8 mSv. The data show that the anthropogenic radiation exposure emanating from the uses of atomic energy or applications of ionizing radiation in technology is very low. (orig./CB) [Deutsch] Der vorliegende Bericht ueber die `Umweltradioaktivitaet und Strahlenbelastung im Jahr 1996` richtet sich an Bundestag und Bundesrat und darueber hinaus an alle an Fragen des Strahlenschutzes interessierte Buerger.

Dieser Wert war zu 60% auf natuerliche und zu 40% auf kuenstliche Strahlenquellen zurueckzufuehren. Den wesentlichen Beitrag zur natuerlichen Strahlenbelastung lieferte das radioaktive Gas Radon in Wohnungen. Die zivilisatorische Strahlenexposition der Bevoelkerung wurde fast ausschliesslich durch die Anwendung radioaktiver Stoffe und ionisierender Strahlen in der Medizin im Rahmen der Diagnostik hervorgerufen. Hier bestehen nach wie vor Moeglichkeiten zur Reduktion der Strahlenbelastung. Im Jahre 1996 waren 340 000 Personen beruflich

Klinisch und therapeutisch wichtig ist die Unterscheidung hinsichtlich des Schädigungsortes im Bereich des Mittelohres, d. h. eine Schalleitungsschwerhörigkeit, oder im Bereich des Innenohres, d. h. eine Schallempfindungsschwerhörigkeit, wobei hier der Schädigungsort auch am Hörnerven oder in den zentralen Hörabschnitten liegen kann. Therapeutisch lassen sich sowohl Schwerhörigkeiten im Bereich des Mittelohres als auch im Innenohr und sogar im Hirnstammbereich (Hirnstammimplantat) behandeln. 1,9 Millionen Schwerhörige haben eine Erkrankung im Mittelohrbereich, d. h. der Schall kann nur ungenügend auf das Innenohr übertragen werden. Die Ursache besteht meist in einer chronischen Mittelohrentzündung, die zu einer Zerstörung des Trommelfells und der Gehörknöchelchenkette geführt haben. Therapeutisch und damit als Prinzip der operativen Hörverbesserung steht primär der Verschluß des Trommelfells oder eine Rekonstruktion der Gehörknöchelchen. Mittelohroperationen werden mikrochirurgisch unter dem Operationsmikroskop durchgeführt, wobei zunächst durch eine sanierende Operation der Entzündungsprozeß entfernt wird und nach einer Ausheilungszeit die Gehörknöchelchenkette durch künstliche Prothesen rekonstruiert werden kann.

Die Pluralbildung im Deutschen - ein Versuch im Rahmen der Optimalitätstheorie

Wegener, Heide

1999-01-01

Full Text Available Die Pluralbildung im Deutschen ist nicht chaotisch, aber komplex. Unabhängig davon, ob man für die Pluralbildung Regeln, Schemata oder die Wortstruktur als Erklärungsmodell benutzt, bleibt die Tatsache einer beachtlichen Zahl miteinander konkurrierender Formen zu erklären. Dies gilt schon deshalb, weil die Variation unter den Pluralformen wohl mit dazu beiträgt, dass trotz der Arbeiten von Mugdan 1977 und Köpcke 1987, 1993, der klaren Darstellung des Pluralsystems in vielen Grammatiken, z.B. Eisenberg 1986, 1989, 1998 noch immer bisweilen die Meinung besteht, die Pluralbildung im Deutschen sei arbiträr.Es soll gezeigt werden, dass das Pluralsystem des Deutschen nach Beschränkungen aufgebaut ist, die morphologischer und silbenphonologischer Natur sind und sich im Rahmen der Optimalitätstheorie (OT beschreiben lassen. Die OT nimmt an, dass Wortformen universalen Beschränkungen (Constraints unterliegen, und dass diese prinzipiell verletzbar sind. Ich werde zunächst die für die Pluralbildung relevanten Beschränkungen definieren, dann an heimischen Pluralformen und -varianten ihr Zusammenwirken zeigen und schließlich den Assimilationsprozess von Fremdwörtern mit Hilfe dieser Beschränkungen und der Beschränkungshierarchien zu erklären versuchen. Daran werden schließlich Überlegungen zu Verarbeitung und Lernbarkeit der Pluralformen geknüpft.

In this paper, an algorithm for time-varying parameter estimation for a large class of nonlinear systems is presented. The proof of the convergence of the estimates to their true values is achieved using Lyapunov theories and does not require that the classical persistent excitation condition be satisfied by the input signal. Since the induction motor (IM) is widely used in several industrial sectors, the algorithm developed is potentially useful for adjusting the controller parameters of variable speed drives. The method proposed is simple and easily implementable in real-time. The application of this approach to on-line estimation of the rotor resistance of IM shows a rapidly converging estimate in spite of measurement noise, discretization effects, parameter uncertainties (e.g. inaccuracies on motor inductance values) and modeling inaccuracies. The robustness analysis for this IM application also revealed that the proposed scheme is insensitive to the stator resistance variations within a wide range. The merits of the proposed algorithm in the case of on-line time-varying rotor resistance estimation are demonstrated via experimental results in various operating conditions of the induction motor. The experimental results obtained demonstrate that the application of the proposed algorithm to update on-line the parameters of an adaptive controller (e.g. IM and synchronous machines adaptive control) can improve the efficiency of the industrial process. The other interesting features of the proposed method include fault detection/estimation and adaptive control of IM and synchronous machines. (author)

A database and tool, IM Browser, for exploring and integrating emerging gene and protein interaction data for Drosophila

Directory of Open Access Journals (Sweden)

Parrish Jodi R

2006-04-01

Full Text Available Abstract Background Biological processes are mediated by networks of interacting genes and proteins. Efforts to map and understand these networks are resulting in the proliferation of interaction data derived from both experimental and computational techniques for a number of organisms. The volume of this data combined with the variety of specific forms it can take has created a need for comprehensive databases that include all of the available data sets, and for exploration tools to facilitate data integration and analysis. One powerful paradigm for the navigation and analysis of interaction data is an interaction graph or map that represents proteins or genes as nodes linked by interactions. Several programs have been developed for graphical representation and analysis of interaction data, yet there remains a need for alternative programs that can provide casual users with rapid easy access to many existing and emerging data sets. Description Here we describe a comprehensive database of Drosophila gene and protein interactions collected from a variety of sources, including low and high throughput screens, genetic interactions, and computational predictions. We also present a program for exploring multiple interaction data sets and for combining data from different sources. The program, referred to as the Interaction Map (IM Browser, is a web-based application for searching and visualizing interaction data stored in a relational database system. Use of the application requires no downloads and minimal user configuration or training, thereby enabling rapid initial access to interaction data. IM Browser was designed to readily accommodate and integrate new types of interaction data as it becomes available. Moreover, all information associated with interaction measurements or predictions and the genes or proteins involved are accessible to the user. This allows combined searches and analyses based on either common or technique-specific attributes

Urinary tract infection (UTI) is a common disease with significant morbidity and economic burden, accounting for a significant part of the workload in clinical microbiology laboratories. Current clinical chemisty point-of-care diagnostics rely on imperfect dipstick analysis which only provides indirect and insensitive evidence of urinary bacterial pathogens. An electronic nose (eNose) is a handheld device mimicking mammalian olfaction that potentially offers affordable and rapid analysis of samples without preparation at athmospheric pressure. In this study we demonstrate the applicability of ion mobility spectrometry (IMS) -based eNose to discriminate the most common UTI pathogens from gaseous headspace of culture plates rapidly and without sample preparation. We gathered a total of 101 culture samples containing four most common UTI bacteries: E. coli, S. saprophyticus, E. faecalis, Klebsiella spp and sterile culture plates. The samples were analyzed using ChemPro 100i device, consisting of IMS cell and six semiconductor sensors. Data analysis was conducted by linear discriminant analysis (LDA) and logistic regression (LR). The results were validated by leave-one-out and 5-fold cross validation analysis. In discrimination of sterile and bacterial samples sensitivity of 95% and specificity of 97% were achieved. The bacterial species were identified with sensitivity of 95% and specificity of 96% using eNose as compared to urine bacterial cultures. These findings strongly demonstrate the ability of our eNose to discriminate bacterial cultures and provides a proof of principle to use this method in urinanalysis of UTI.

Instrumentale Spielformeln und Vokale Verzierungen im 16.Jahrhundert

Directory of Open Access Journals (Sweden)

Göllner, Theodor

2001-12-01

Full Text Available In the music of the 16th century, stereotype four-note formulas are found in the instrumental as well as in the vocal idiom. Although frequently identical in appearance, their functions are very different. While indispensable in the instrumental idiom, particularly in keyboard music, where they represent the very essence of instruction in 15th-century organ treatises and fundamenta, they appear in vocal music only as additions to finished compositions or existing practices. What amounts to an absolute necessity in one case is merely an ornamental supplement in the other. In vocal music it is treated as a matter of performance carried out by a qualified soloist and limited to the musical centers of Italy. The present article raises the question as to how the genuinely instrumental and widely spread keyboard practice made its impact on the vocal ornaments of the singer, whose primary concern is the musical communication of language.

[de] Die in der Musik des 16. Jahrhunderts im Instrumentalen wie im Vokalen vorkommenden, meist viertönigen, stereotypen Formeln sind zwar in beiden Bereichen weitgehend identisch, doch von höchst unterschiedlicher Funktion. Während sie im Instrumentalen, besonders in der Tastenmusik, unverzichtbar sind und schon im 15. Jahrhundert den Kern der Orgeltraktate und Fundamenta bilden, treten sie im Vokalen zu einer fertigen Komposition oder bestehenden Praxis hinzu. Was im einen Fall eine unbedingte Notwendigkeit ist, wird im anderen zu einem nachträglichen Ornament, das sich oft erst bei der Aufftührung einstellt, den qualifizierten Solosänger voraussetzt und auf die musikalischen Zentren Italiens konzentriert war. Der Artikel versucht zu klären, wie sich das genuin instrumentale, allgemein verbreitete Tastenspiel auf die spezielle Verzierungskunst des Sängers auswirkt, dessen primäre Aufgabe es ist, Sprache musikalisch zu vermitteln.

MALDI Imaging Mass Spectrometry (MALDI-IMS―Application of Spatial Proteomics for Ovarian Cancer Classification and Diagnosis

Directory of Open Access Journals (Sweden)

Johan O. R. Gustafsson

2011-01-01

Full Text Available MALDI imaging mass spectrometry (MALDI-IMS allows acquisition of mass data for metabolites, lipids, peptides and proteins directly from tissue sections. IMS is typically performed either as a multiple spot profiling experiment to generate tissue specific mass profiles, or a high resolution imaging experiment where relative spatial abundance for potentially hundreds of analytes across virtually any tissue section can be measured. Crucially, imaging can be achieved without prior knowledge of tissue composition and without the use of antibodies. In effect MALDI-IMS allows generation of molecular data which complement and expand upon the information provided by histology including immuno-histochemistry, making its application valuable to both cancer biomarker research and diagnostics. The current state of MALDI-IMS, key biological applications to ovarian cancer research and practical considerations for analysis of peptides and proteins on ovarian tissue are presented in this review.

Purpose: To evaluate the role of contrast enhanced MRI in quantifying signal changes of the inferior alveolar nerve following inflammatory changes of the mandible. Material and methods: 30 patients with inflammatory changes of the mandible underwent MRI of the face. Both sides of the mandible, the affected as well as the unaffected healthy side were evaluated retrospectively. Regions of interest were placed at 5 defined placed on both sides to assess signal intensity before and after intravenous application of paramagnetic contrast agent. The results of the measurements were compared between the healthy and the affected side (t-test, p<0,05) and correlated with clinical findings (t-test, p<0.05). Results: All patients with hypesthesia of the inferior alveolar nerve in areas of the lips or chin (n=4) showed a marked increase in signal intensity from 35% to 83% distal to the inflammatory process. Patients without sensitivity disorders showed less increase in signal intensity with a maximum of 51% distal to the inflammatory process. In nearly all patients no contrast enhancement was observed distal to the first molar on the unaffected side. Conclusions: Quantitative analysis of contrast enhanced MRI of the neurovascular bundle is able to show pathologic mandibular lesions. In case of inflammatory changes of the mandible the neurovascular bundle is able to show pathologic mandibular lesions. In case of inflammatory changes of the mandible the neurovascular bundle shows a significant increase in signal intensity distal to the lesion compared to the unaffected healthy side of the mandible.

2014-09-01

Tandem N-methylpyrrole-N-methylimidazole (Py-Im) polyamides with good sequence-specific DNA-alkylating activities have been designed and synthesized. Three alkylating tandem Py-Im polyamides with different linkers, which each contained the same moiety for the recognition of a 10 bp DNA sequence, were evaluated for their reactivity and selectivity by DNA alkylation, using high-resolution denaturing gel electrophoresis. All three conjugates displayed high reactivities for the target sequence. In particular, polyamide 1, which contained a β-alanine linker, displayed the most-selective sequence-specific alkylation towards the target 10 bp DNA sequence. The tandem Py-Im polyamide conjugates displayed greater sequence-specific DNA alkylation than conventional hairpin Py-Im polyamide conjugates (4 and 5). For further research, the design of tandem Py-Im polyamide conjugates could play an important role in targeting specific gene sequences. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

We investigate the constellation design and symbol error rate (SER) of set-partitioned (SP) quadrature amplitude modulation (QAM) formats. Based on the SER analysis, we derive the adaptive bit and power loading algorithm for SP QAM based intensity-modulation direct-detection (IM/DD) orthogonal frequency division multiplexing (OFDM). We experimentally show that the proposed system significantly outperforms the conventional adaptively-loaded IM/DD OFDM and can increase the data rate from 36 Gbit/s to 42 Gbit/s in the presence of severe dispersion-induced spectral nulls after 40-km single-mode fiber. It is also shown that the adaptive algorithm greatly enhances the tolerance to fiber nonlinearity and allows for more power budget.

2012-11-01

While the use of detergents is necessary for a variety of protein isolation preparation protocols, often prior to mass spectral (MS) analysis, they are not compatible with MS analysis due to ion suppression and adduct formation. This manuscript describes optimization of detergent removal, using commercially available SDS depletion spin columns containing an affinity resin, providing for both increased protein recovery and thorough SDS removal. Ion mobility spectrometry coupled with mass spectrometry (IMS-MS) allowed for a concurrent analysis of both analyte and detergent. In the case of both proteins and peptides, higher detergent concentrations than previously reported provided an increase of sample recovery; however there was a limit as SDS was detected by IMS-MS at higher levels of SDS indicating incomplete detergent depletion. The results also suggest optimal conditions for SDS removal are dependent on the sample concentration. Overall, this study provides a useful guide for proteomic studies where SDS is required for efficient sample preparation.

Motor vehicles contribute much to urban air pollution. As a result, most governments have enacted emission standards that significantly lower pollutant emission levels from new motor vehicles. For example, vehicles built in the United States emit 95 % fewer pollutants than uncontrolled vehicles when they are new. However, studies indicate that proper maintenance is needed to obtain the full benefit of vehicle emission controls. Furthermore, there is evidence that a significant percentage of the vehicle fleet is not properly maintained. This has led to the creation of motor vehicle Inspection/Maintenance (I/M) Programs. I/M programs inspect vehicles for indications that they are emitting excessive quantities of pollutants. Vehicles that fail the inspection must be repaired in order to comply with program requirements. The first I/M programs were implemented in the United States in the early 1970s. With substantial urging from the federal government, most of the U.S. states with severe air pollution problems have implemented I/M programs. Recently, with the passage of the U.S. Clean Air Act Amendments of 1990, many states have been required to significantly upgrade the performance and coverage of their I/M programs. I/M programs also have been implemented in Europe and recently in Asia. This presentation reviews developments in I/M programs for light-duty gasoline powered vehicles. Developments in I/M programs for diesel powered vehicles are briefly described. (author)

Respuestas faciales ante imágenes de advertencia de tabaco

Directory of Open Access Journals (Sweden)

M. A. Muñoz

Full Text Available Resumen En 2003, la Comisión Europea propuso una serie de advertencias visuales para ser incluidas en los embalajes de tabaco, con el objetivo de motivar a los fumadores a dejar de fumar y promover actitudes negativas hacia el tabaco. El objetivo de este estudio fue evaluar el impacto de las advertencias sanitarias mediante autoinformes y medidas psicofisiológicas. Cincuenta sujetos sanos (19-23 años visionaron un conjunto de treinta y seis imágenes de diferente contenido emocional y veinticuatro del banco de imágenes preventivas propuestas por la Comisión Europea. Se registró la actividad eléctrica de los músculos cigomático mayor y corrugador mientras los sujetos visionaban estas imágenes. A continuación, los participantes evaluaban las imágenes en las dimensiones de agradabilidad y activación. Los resultados muestran una mayor actividad eléctrica del musculo corrugador ante la presentación de imágenes desagradables comparadas con advertencias desagradables incluidas en los paquetes de tabaco. Estos resultados sugieren que la campaña preventiva podría beneficiarse de imágenes preventivas más impactantes, promoviendo así la activación del sistema motivacional evitativo/defensivo.

A proposal for a determination method of element division on an analytical model for finite element elastic waves propagation analysis

2010-01-01

This study proposes an element size selection method named the 'Impact-Meshing (IM) method' for a finite element waves propagation analysis model, which is characterized by (1) determination of element division of the model with strain energy in the whole model, (2) static analysis (dynamic analysis in a single time step) with boundary conditions which gives a maximum change of displacement in the time increment and inertial (impact) force caused by the displacement change. In this paper, an example of application of the IM method to 3D ultrasonic wave propagation problem in an elastic solid is described. These examples showed an analysis result with a model determined by the IM method was convergence and calculation time for determination of element subdivision was reduced to about 1/6 by the IM Method which did not need determination of element subdivision by a dynamic transient analysis with 100 time steps.

The properties and potential liabilities of drug candidate are investigated in detailed ADME assays and in toxicity studies, where findings are placed in context of exposure to dosed drug and metabolites. The complex nature of biological samples may necessitate work-up procedures prior to high performance liquid chromatography-mass spectrometric (HPLC-MS) analysis of endogenous or xenobiotic compounds. This concept can readily be applied to biological fluids such as blood or urine, but in localized samples such as organs and tissues potentially important spatial, thus anatomical, information is lost during sample preparation as the result of homogenization and extraction procedures. However, the localization of test article or spatial identification of metabolites may be critical to the understanding of the mechanism of target-organ toxicity and its relevance to clinical safety. Tissue imaging mass spectrometry (IMS) by matrix-assisted laser desorption ionization (MALDI) and ion trap mass spectrometry (MS) with higher order mass spectrometric scanning functions was utilized for localization of dosed drug or metabolite in tissue. Laser capture microscopy (LCM) was used to obtain related samples from tissue for analyses by standard MALDI-MS and HPLC-MS. In a toxicology study, rats were administered with a high dosage of a prodrug for 2 weeks. Birefringent microcrystalline material (10-25 microm) was observed in histopathologic formalin-fixed tissue samples. Direct analysis by IMS provided the identity of material in the microcrystals as circulating active drug while maintaining spatial orientation. Complementary data from visual cross-polarized light microscopy as well as standard MALDI-MS and HPLC-MS experiments on LCM samples validated the qualitative results obtained by IMS. Furthermore, the HPLC-MS analysis on the LCM samples afforded a semi-quantitative assessment of the crystalline material in the tissue samples. IMS by MALDI ion trap MS proved sensitive

An evaluation of static headspace-multicapillary column-gas chromatography-ion mobility spectrometry (SHS-MCC-GC-IMS) has been undertaken to assess its applicability for the determination of 32 volatile compounds (VCs). The key experimental variables of sample incubation time and temperature have been evaluated alongside the MCC-GC variables of column polarity, syringe temperature, injection temperature, injection volume, column temperature and carrier gas flow rate coupled with the IMS variables of temperature and drift gas flow rate. This evaluation resulted in six sets of experimental variables being required to separate the 32 VCs. The optimum experimental variables for SHS-MCC-GC-IMS, the retention time and drift time operating parameters were determined; to normalise the operating parameters, the relative drift time and normalised reduced ion mobility for each VC were determined. In addition, a full theoretical explanation is provided on the formation of the monomer, dimer and trimer of a VC. The optimum operating condition for each VC calibration data was obtained alongside limit of detection (LOD) and limit of quantitation (LOQ) values. Typical detection limits ranged from 0.1ng bis(methylthio)methane, ethylbutanoate and (E)-2-nonenal to 472ng isovaleric acid with correlation coefficient (R(2)) data ranging from 0.9793 (for the dimer of octanal) through to 0.9990 (for isobutyric acid). Finally, the developed protocols were applied to the analysis of malodour in sock samples. Initial work involved spiking an inert matrix and sock samples with appropriate concentrations of eight VCs. The average recovery from the inert matrix was 101±18% (n=8), while recoveries from the sock samples were lower, that is, 54±30% (n=8) for sock type 1 and 78±24% (n=6) for sock type 2. Finally, SHS-MCC-GC-IMS was applied to sock malodour in a field trial based on 11 volunteers (mixed gender) over a 3-week period. By applying the SHS-MCC-GC-IMS database, four VCs were

Healthcare organizations and systems around the world lag far behind banking, manufacturing, travel and other industries in their use of information management/information technology (IM/IT) to deliver high-quality products and services. Across Canada, healthcare organizations, as well as governments, understand that information and information technology are needed to deliver quality care and to sustain our publicly funded health system. However, insufficient funding, few experienced resources, lack of strong leadership and absence of clear business/clinical rationale have restricted innovation and advancement in the use of IM/IT to improve healthcare delivery and patient outcomes.

This work describes a simple approach for the untargeted profiling of volatile compounds for the authentication of the botanical origins of honey based on resolution-optimized HS-GC-IMS combined with optimized chemometric techniques, namely PCA, LDA, and kNN. A direct comparison of the PCA-LDA models between the HS-GC-IMS and 1 H NMR data demonstrated that HS-GC-IMS profiling could be used as a complementary tool to NMR-based profiling of honey samples. Whereas NMR profiling still requires comparatively precise sample preparation, pH adjustment in particular, HS-GC-IMS fingerprinting may be considered an alternative approach for a truly fully automatable, cost-efficient, and in particular highly sensitive method. It was demonstrated that all tested honey samples could be distinguished on the basis of their botanical origins. Loading plots revealed the volatile compounds responsible for the differences among the monofloral honeys. The HS-GC-IMS-based PCA-LDA model was composed of two linear functions of discrimination and 10 selected PCs that discriminated canola, acacia, and honeydew honeys with a predictive accuracy of 98.6%. Application of the LDA model to an external test set of 10 authentic honeys clearly proved the high predictive ability of the model by correctly classifying them into three variety groups with 100% correct classifications. The constructed model presents a simple and efficient method of analysis and may serve as a basis for the authentication of other food types.

Auf Basis einer neoformalistisch orientierten Filmanalyse nach Bordwell und Thompson (2008, wird anhand von drei Filmsequenzen eine mögliche Lesart des Kinderfilms "Heidi" (Marcus 2005 entwickelt, um die filmstilistische Darstellung der Gehbehinderung des Mädchens Klara zu untersuchen. Die Ergebnisse werden mit theoretischen Überlegungen zur Problematik der Begriffsbestimmung von Körperbehinderung sowie zur Mobilität und Selbstbestimmung von Menschen mit Körperbehinderungen in Bezug gesetzt. Dabei zeigt sich im Wesentlichen, dass im Kinderfilm "Heidi" (Marcus 2005 Klaras Gehbehinderung als 'heilbare Krankheit' und der Rollstuhl als Einschränkung von Mobilität begriffen wird. Außerdem unterliegt Klara aufgrund ihrer Körperbehinderung überwiegend der Fremdbestimmung von Erwachsenen. Zur Klärung wahrscheinlicher filmischer Bildungspotenziale werden die Ergebnisse schließlich anhand der von Jörissen und Marotzki (2009 entwickelten Orientierungsdimensionen "Wissens-, Handlungs-, Grenz- und Biographiebezug" diskutiert. This article aims to bridge a knowledge gap by showing ways of representing disabilities in the German children film genre. Using Bordwell and Thomson's (2008 neoformalistically orientated film analysis approach, the movie "Heidi" (Marcus 2005 is analysed. Bordwell and Thompson's (2008 method is applied to three sequences of "Heidi" in order to present an interpretation and to discuss the representation of Clara's walking impediment. The results are then associated with theoretical considerations regarding the mobility and self-determination of people with disabilities and problematic definitions of the term 'physical disability'. It is shown that characters in the children's film "Heidi" (Marcus 2005 regard Clara's walking impediment as a 'curable disease' and the wheelchair as a limitation

Full Text Available The development of packed based multimedia networks reached a turning point when the ITU-T and the ETSIhave incorporated the IMS to the NGN. With the fast development of mobile communication more and more services andcontent are available. In contrast with fix network telephony both the services and the devices are personalized in the “mobileworld”. Services, known from the Internet - like e-mail, chat, browsing, presence, etc. – are already available via mobiledevices as well. The IMS originally wanted to exploit both the benefits of mobile networks and the fancy services of theInternet. But today it is already more than that. IMS is the core of the next generation telecommunication networks and abasis for fix-mobile convergent services. The fact however that IMS was originally a “mobile” standard, where IPv6 was notoddity generated some problems for the fix networks, where IPv4 is used. In this article I give an overview of these problemsand mention some solutions as well.

Comets are of enormous scientific interest for many reasons. They are primitive bodies that date back to the earliest stages of solar system formation and, because of their small size and because they have been stored in the outer reaches of the solar system, their pristine nature has been preserved better than for any other class of body. They are extremely rich in highly volatile elements, many in the form of ices, and are richer in organic matter than any other known solar system body. It is strongly suspected that in addition to their content of primordial solar nebular material, they also incorporate unprocessed matter from the interstellar medium. Impacts by comets occur onto all the planets and satellites, often with major consequences (e.g., the dinosaur extinction event at the KIT boundary), or sometimes just providing a spectacular cosmic event (e.g., the collision of comet Shoemaker-Levy 9 with Jupiter). A mission to analyze a cometary nucleus must be capable of detecting and identifying over 30 molecular species among several different chemical groups. The Hummingbird Mission will rendezvous with, orbit, characterize, and make multiple descents to the nucleus of a comet. Hummingbird will employ a Gas Chromatograph - Ion Mobility Spectrometer (GC-IMS) as part-of a suite of sophisticated instruments for a comprehensive in situ elemental, molecular, and isotopic analysis of the comet.

The Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) is commonly used to assess baseline and post-injury cognition among athletes in North America. Despite this, several studies have questioned the reliability of ImPACT when given at intervals employed in clinical practice. Poor test-retest reliability reduces test sensitivity to cognitive decline, increasing the likelihood that concussed athletes will be returned to play prematurely. We recently showed that the reliability of ImPACT can be increased when using a new composite structure and the aggregate of two baselines to predict subsequent performance. The purpose of the present study was to confirm our previous findings and determine whether the addition of a third baseline would further increase the test-retest reliability of ImPACT. Data from 97 English speaking professional hockey players who had received at least 4 ImPACT baseline evaluations were extracted from a National Hockey League Concussion Program database. Linear regression was used to determine whether each of the first three testing sessions accounted for unique variance in the fourth testing session. Results confirmed that the aggregate baseline approach improves the psychometric properties of ImPACT, with most indices demonstrating adequate or better test-retest reliability for clinical use. The aggregate baseline approach provides a modest clinical benefit when recent baselines are available - and a more substantial benefit when compared to approaches that obtain baseline measures only once during the course of a multi-year playing career. Pending confirmation in diverse samples, neuropsychologists are encouraged to use the aggregate baseline approach to best quantify cognitive change following sports concussion.

The complexes [MeBu{sub 3}N]{sub 2}[UCl{sub 6}] and [BuMe{sub 2}Im]{sub 2}[UCl{sub 6}] were characterized in the solid state and in solution of [MeBu{sub 3}N][Tf{sub 2}N], [BuMe{sub 2}Im][Tf{sub 2}N] and [BuMeIm][Tf{sub 2}N] room temperature ionic liquids using single-crystal XRD, EXAFS, electrochemistry, UV-visible absorption spectroscopy and NMR. In the solid and in solution, the existence of hydrogen bonding between the anionic UCl{sub 6}{sup 2-} complex and the ionic liquid cations were revealed by these techniques. The MeBu{sub 3}N{sup +} cation interacts with UCl{sub 6}{sup 2-} via the protons on the alpha carbon atoms of nitrogen. The protons of the imidazolium ring account for the interaction between the BuMe{sub 2}Im+ cation and the UCl{sub 6}{sup 2-} anion. For the BuMeIm{sup +} cation the major interaction was confirmed between the most acidic proton on C(2) and UCl{sub 6}{sup 2-}. The experimental results also show that the intensity of the interaction between the UCl{sub 6}{sup 2-} anion and the cation varies with the ionic liquid cation in the following order: MeBu{sub 3}N{sup +} {approx} BuMe{sub 2}Im{sup +} << BuMeIm{sup +}.

Handover Based IMS Registration Scheme for Next Generation Mobile Networks

Directory of Open Access Journals (Sweden)

Shireen Tahira

2017-01-01

Full Text Available Next generation mobile networks aim to provide faster speed and more capacity along with energy efficiency to support video streaming and massive data sharing in social and communication networks. In these networks, user equipment has to register with IP Multimedia Subsystem (IMS which promises quality of service to the mobile users that frequently move across different access networks. After each handover caused due to mobility, IMS provides IPSec Security Association establishment and authentication phases. The main issue is that unnecessary reregistration after every handover results in latency and communication overhead. To tackle these issues, this paper presents a lightweight Fast IMS Mobility (FIM registration scheme that avoids unnecessary conventional registration phases such as security associations, authentication, and authorization. FIM maintains a flag to avoid deregistration and sends a subsequent message to provide necessary parameters to IMS servers after mobility. It also handles the change of IP address for user equipment and transferring the security associations from old to new servers. We have validated the performance of FIM by developing a testbed consisting of IMS servers and user equipment. The experimental results demonstrate the performance supremacy of FIM. It reduces media disruption time, number of messages, and packet loss up to 67%, 100%, and 61%, respectively, as compared to preliminaries.

Robust stator resistance identification of an IM drive using model reference adaptive system

International Nuclear Information System (INIS)

Madadi Kojabadi, Hossein; Abarzadeh, Mostafa; Aghaei Farouji, Said

2013-01-01

Highlights: ► We estimate the stator resistance and rotor speed of the IM. ► We proposed a new quantity to estimate the speed and stator resistance of IM. ► The proposed algorithm is robust to rotor resistance variations. ► We estimate the IM speed and stator resistance simultaneously to avoid speed error. - Abstract: Model reference adaptive system (MRAS) based robust stator resistance estimator for sensorless induction motor (IM) drive is proposed. The MRAS is formed with a semi-active power quantity. The proposed identification method can be achieved with on-line tuning of the stator resistance with robustness against rotor resistance variations. Stable and efficient estimation of IM speed at low region will be guaranteed by simultaneous identification of IM speed and stator resistance. The stability of proposed stator resistance estimator is checked through Popov’s hyperstability theorem. Simulation and experimental results are given to highlight the feasibility, the simplicity, and the robustness of the proposed method.

The industry-led, international intelligent manufacturing systems (IMS) program provides a special vehicle for joint research and development between government, industry and academia in the United States, Canada, Japan, Australia, and Europe. Since its beginning in 1989, the IMS program has progressed through a feasibility phase which demonstrated that international legal barriers, trade issues, and intellectual property problems could be overcome. The program is constructed to provide higher quality design, customized products, shorter delivery cycles and lower costs. Interactions between partner companies have led to new business opportunities for mutual profit and some claim to have learned strategic information about their international competitors. The IMS program is growing through the participation of hundreds of corporate and university partners who share responsibilities in specific projects and jointly reap benefits for their manufacturing products and processes. The logic for choosing or not choosing the IMS mechanisms will be discussed and R and D projects will be identified.

In many cases, the meta-information which is described consists of the classification of a resource in relation to a taxonomy or thesaurus. Agrega is a network of learning object repositories in which an LOM profile, called LOM-ES, has been used to label the objects. Part of the meta-information described corresponds to the classification of the object with respect to a group of taxonomies and a thesaurus, which have had to be described using the ims vdex standard to enable them to be managed from the federation nodes.

Theoretical predictor for candidate structure assignment from IMS data of biomolecule-related conformational space.

Science.gov (United States)

Schenk, Emily R; Nau, Frederic; Fernandez-Lima, Francisco

2015-06-01

The ability to correlate experimental ion mobility data with candidate structures from theoretical modeling provides a powerful analytical and structural tool for the characterization of biomolecules. In the present paper, a theoretical workflow is described to generate and assign candidate structures for experimental trapped ion mobility and H/D exchange (HDX-TIMS-MS) data following molecular dynamics simulations and statistical filtering. The applicability of the theoretical predictor is illustrated for a peptide and protein example with multiple conformations and kinetic intermediates. The described methodology yields a low computational cost and a simple workflow by incorporating statistical filtering and molecular dynamics simulations. The workflow can be adapted to different IMS scenarios and CCS calculators for a more accurate description of the IMS experimental conditions. For the case of the HDX-TIMS-MS experiments, molecular dynamics in the "TIMS box" accounts for a better sampling of the molecular intermediates and local energy minima.

ImSET 3.1: Impact of Sector Energy Technologies Model Description and User's Guide

Energy Technology Data Exchange (ETDEWEB)

Scott, Michael J.; Livingston, Olga V.; Balducci, Patrick J.; Roop, Joseph M.; Schultz, Robert W.

2009-05-22

This 3.1 version of the Impact of Sector Energy Technologies (ImSET) model represents the next generation of the previously-built ImSET model (ImSET 2.0) that was developed in 2005 to estimate the macroeconomic impacts of energy-efficient technology in buildings. In particular, a special-purpose version of the Benchmark National Input-Output (I-O) model was designed specifically to estimate the national employment and income effects of the deployment of Office of Energy Efficiency and Renewable Energy (EERE)–developed energy-saving technologies. In comparison with the previous versions of the model, this version features the use of the U.S. Bureau of Economic Analysis 2002 national input-output table and the central processing code has been moved from the FORTRAN legacy operating environment to a modern C++ code. ImSET is also easier to use than extant macroeconomic simulation models and incorporates information developed by each of the EERE offices as part of the requirements of the Government Performance and Results Act. While it does not include the ability to model certain dynamic features of markets for labor and other factors of production featured in the more complex models, for most purposes these excluded features are not critical. The analysis is credible as long as the assumption is made that relative prices in the economy would not be substantially affected by energy efficiency investments. In most cases, the expected scale of these investments is small enough that neither labor markets nor production cost relationships should seriously affect national prices as the investments are made. The exact timing of impacts on gross product, employment, and national wage income from energy efficiency investments is not well-enough understood that much special insight can be gained from the additional dynamic sophistication of a macroeconomic simulation model. Thus, we believe that this version of ImSET is a cost-effective solution to estimating the economic

Estimating Full IM240 Emissions from Partial Test Results: Evidence from Arizona.

Science.gov (United States)

Ando, Amy W; Harrington, Winston; McConnell, Virginia

1999-10-01

The expense and inconvenience of enhanced-vehicle-emissions testing using the full 240-second dynamometer test has led states to search for ways to shorten the test process. In fact, all states that currently use the IM240 allow some type of fast-pass, usually as early in the test as second 31, and Arizona has allowed vehicles to fast-fail after second 93. While these shorter tests save states millions of dollars in inspection lanes and driver costs, there is a loss of information since test results are no longer comparable across vehicles. This paper presents a methodology for estimating full 240-second results from partial-test results for three pollutants: HC, CO, and NO x . If states can convert all tests to consistent IM240 readings, they will be able to better characterize fleet emissions and to evaluate the impact of inspection and maintenance and other programs on emissions over time. Using a random sample of vehicles in Arizona which received full 240-second tests, we use regression analysis to estimate the relationship between emissions at second 240 and emissions at earlier seconds in the test. We examine the influence of other variables such as age, model-year group, and the pollution level itself on this relationship. We also use the estimated coefficients in several applications. First, we try to shed light on the frequent assertion that the results of the dynamometer test provide guidance for vehicle repair of failing vehicles. Using a probit analysis, we find that the probability that a failing vehicle will pass the test on the first retest is greater the longer the test has progressed. Second, we test the accuracy of our estimates for forecasting fleet emissions from partial-test emissions results in Arizona. We find forecasted fleet average emissions to be very close to the actual fleet averages for light-duty vehicles, but not quite as good for trucks, particularly when NO x emissions are forecast.

Schaefer, W [Heidelberg Univ. (Germany). Inst. fuer Umweltphysik

1999-07-01

The book describes reactive transport of organic pollutants in ground water and its quantitative monitoring by means of numerical reaction transport models. A brief introduction dealing with the importance of and hazards to ground water and opportunities for making use of ground water models is followed by a more detailed chapter on organic pollutants in ground water. Here the focus is on organochlorine compounds and mineral oil products. Described are propagation mechanisms for these substances in the ground and, especially, their degradability in ground water. A separate chapter is dedicated to possibilities for cleaning up polluted ground water aquifers. The most important decontamination techniques are presented, with special emphasis on in-situ processes with hydraulic components. Moreover, this chapter discusses the self-cleaning capability of aquifers and the benefits of the application of models to ground water cleanup. In the fourth chapter the individual components of reaction transport models are indicated. Here it is, inter alia, differences in the formulation of reaction models as to their complexity, and coupling between suspended matter transport and reaction processes that are dealt with. This chapter ends with a comprehensive survey of literature regarding the application of suspended matter transport models to real ground water accidents. Chapter 5 consists of a description of the capability and principle of function of the reaction transport model TBC (transport biochemism/chemism). This model is used in the two described applications to the reactive transport of organic pollutants in ground water. (orig.)

Mr., J. Ravi Kumar; Banakara, Basavaraja, Dr.

2017-08-01

This paper presents electromagnetic and thermal behavior of Induction Motor (IM) through the modeling and analysis by applying multiphysics coupled Finite Element Analysis (FEA). Therefore prediction of the magnetic flux, electromagnetic torque, stator and rotor losses and temperature distribution inside an operating electric motor are the most important issues during its design. Prediction and estimation of these parameters allows design engineers to decide capability of the machine for the proposed load, temperature rating and its application for which it is being designed ensuring normal motor operation at rated conditions. In this work, multiphysics coupled electromagnetic - thermal modeling and analysis of induction motor at rated and high frequency has carried out applying Arkkio’s torque method. COMSOL Multiphysics software is used for modeling and finite element analysis of IM. Transient electromagnetic torque, magnetic field distribution, speed-torque characteristics of IM were plotted and studied at different frequencies. This proposed work helps in the design and prediction of accurate performance of induction motor specific to various industrial drive applications. Results obtained are also validated with experimental analysis. The main purpose of this model is to use it as an integral part of the design aiming to system optimization of Variable Speed Drive (VSD) and its components using coupled simulations.

Signal Processing for Indian and Pakistan Nuclear Tests Recorded at IMS Stations Located in Israel

Science.gov (United States)

Gitterman, Y.; Pinsky, V.; Hofstetter, R.

- In compliance with the Comprehensive Nuclear-Test-Ban-Treaty (CTBT) the International Monitoring System (IMS) was designed for detection and location of the clandestine Nuclear Tests (NT). Two auxiliary IMS seismic stations MRNI and EIL, deployed recently, were subjected to detectability, travel-time calibration and discrimination analysis. The study is based on the three recent 1998 underground nuclear explosions: one of India and two of Pakistan, which provided a ground-truth test of the existing IMS. These events, attaining magnitudes of 5.2, 4.8 and 4.6 correspondingly, were registered by many IMS and other seismic stations.The MRNI and EIL broadband (BB) stations are located in Israel at teleseismic distances (from the explosions) of 3600, 2800 and 2700km, respectively, where the signals from the tests are already weak. The Indian and the second Pakistan NT were not detected by the short-period Israel Seismic Network (ISN), using standard STA/LTA triggering. Therefore, for the chosen IMS stations we compare the STA/LTA response to the results of the more sensitive Murdock-Hutt (MH) and the Adaptive Statistically Optimal Detector (OD) that showed triggering for these three events. The second Pakistan NT signal arrived at the ISN and the IMS stations in the coda of a strong Afghanistan earthquake and was further disturbed by a preceding signal from a local earthquake. However, the NT signal was successfully extracted at EIL and MRNI stations using MH and OD procedures. For comparison we provide the signal analysis of the cooperating BB station JER, with considerably worse noise conditions than EIL and MRNI, and show that OD can detect events when the other algorithms fail. Using the most quiet EIL station, the most sensitive OD and different bandpass filters we tried in addition to detect the small Kazakh chemical 100-ton calibration explosion of 1998, with magnitude 3.7 at a distance approaching 4000km. The detector response curve showed uprising in the

Full Text Available Der Grand Prix Eurovision ist seit Jahrzehnten eine der bekanntesten Unterhaltungssendungen im europäischen Raum. Dennoch erregte es Verwunderung, wenn der Schreibende Bekannten darüber berichtete, daß dies ein Forschungsgegenstand sei. Wurde von Interviews mit Grand Prix-Fans erzählt, so fielen schnell Aussagen wie: „Wie kann man sich nur für so etwas Abseitiges und Triviales wie den Grand Prix interessieren“. Dennoch bin ich der Meinung, daß Fankulturen für die entstehende Mediengesellschaft ein nicht unwichtiges Forschungsthema darstellen. Zwar geht es nicht um eine medienpädagogische Fragestellung im engeren Sinne; die Fans des Grand Prix Eurovision sind dem Jugendalter längst entwachsen. Dennoch handelt es sich bei Fangemeinschaften um Phänomene, die im Rahmen von Jugend- und Kinderkulturen von besonderer Relevanz sind. So meint Winter (1997, daß jugendliche Fanwelten eine bedeutende Rolle als Kristallisationspunkte kultureller Differenzierung spielen: ,Die Zugehörigkeit zu einer Fan weit ist Teil der jugendlichen Lebensbewältigung in der Postmoderne, denn in der Gemeinschaft der Fans können Jugendliche emotionale Allianzen eingehen, außeralltäglichen Beschäftigungen nachgehen, expressive Identitätsmuster gemeinschaftlich realisieren und sich mit ihrer Lebenssituation als Heranwachsende auseinandersetzen“ (Winter 1997, S. 51f..

Xu, Longtao; Jin, Shilei; Li, Yifei

2016-04-18

We present the first down-conversion intensity modulated-direct detection (IM-DD) RF photonic link that achieves frequency down-conversion using the nonlinear optical phase modulation inside a Mach-Zehnder (MZ) modulator. The nonlinear phase modulation is very sensitive and it can enable high RF-to-IF conversion efficiency. Furthermore, the link linearity is enhanced by canceling the nonlinear distortions from the nonlinear phase modulation and the MZ interferometer. Proof-of-concept measurement was performed. The down-conversion IM-DD link demonstrated 28dB improvement in distortion levels over that of a conventional IM-DD link using a LiNbO3 MZ modulator.

Results from an Interval Management (IM) Flight Test and Its Potential Benefit to Air Traffic Management Operations

NASA's first Air Traffic Management Technology Demonstration (ATD-1) subproject successfully completed a 19-day flight test of an Interval Management (IM) avionics prototype. The prototype was built based on IM standards, integrated into two test aircraft, and then flown in real-world conditions to determine if the goals of improving aircraft efficiency and airport throughput during high-density arrival operations could be met. The ATD-1 concept of operation integrates advanced arrival scheduling, controller decision support tools, and the IM avionics to enable multiple time-based arrival streams into a high-density terminal airspace. IM contributes by calculating airspeeds that enable an aircraft to achieve a spacing interval behind the preceding aircraft. The IM avionics uses its data (route of flight, position, etc.) and Automatic Dependent Surveillance-Broadcast (ADS-B) state data from the Target aircraft to calculate this airspeed. The flight test demonstrated that the IM avionics prototype met the spacing accuracy design goal for three of the four IM operation types tested. The primary issue requiring attention for future IM work is the high rate of IM speed commands and speed reversals. In total, during this flight test, the IM avionics prototype showed significant promise in contributing to the goals of improving aircraft efficiency and airport throughput.

Toward an Intelligent Ion Mobility Spectrometer (IMS)

International Nuclear Information System (INIS)

McJunkin, Timothy R.; Scott, Jill R.; Miller, Carla J.

2003-01-01

The ultimate goal is to design and build a very smart ion mobility spectrometer (IMS) that can operate autonomously. To accomplish this, software capable of interpreting spectra so that it can be used in control loops for data interpretation as well as adjusting instrument parameters is being developed. Fuzzy logic and fuzzy numbers are used in this IMS spectra classification scheme. Fuzzy logic provides a straight forward method for developing a classification/detection system, whenever rules for classifying the spectra can be described linguistically. Instead of using 'max' and 'min' values, the product of the truth values is used to determine class membership. Using the product allows rule-bases that utilize the AND function to allow each condition to discount truth value in determining membership, while rule-bases with an OR function are allowed to accumulate membership. Fuzzy numbers allow encapsulation of the uncertainties due to ion mobility peak widths as well as measured instrumental parameters, such as pressure and temperature. Associating a peak with a value of uncertainty, in addition to making adjustments to the mobility calculation based on variations in measured parameters, enables unexpected shifts to be more reliably detected and accounted for; thereby, reducing the opportunity for 'false negative' results. The measure of uncertainty is anticipated to serve the additional purpose of diagnosing the operational conditions of the IMS instrument.

Full Text Available Ergonomics has developed significantly for the prevention of related accidents. Its implementation, however, depends on the existing management system within a company. The integrated management system (IMS is frequently implemented in industry, which is an integration of ISO 9001, ISO 14001, and OHSAS 18001. The objectives of this research were to analyze the effects of IMS implementation on work ergonomics and to find the influencing factors. The methods used were the 4x4 method for investigating accidents; interviews; and a questionnaire for workers and managers at an electricity company. The subjects were divided into three levels, namely: top management, middle management, and workers. Logistic regression was used to analyze and estimate the effects of one or more management variables on ergonomics related accidents. The results showed that the implementation of IMS has supported work ergonomics very well based on the average scores, which ranged from 2.99 to 3.38. The logistic regression showed that the most influential IMS on work ergonomics was the Do (D of Deming’s PDCA cycle, whereas the most influential parameter for ergonomics accident prevention was Policy (P and Do (D at the top management level.

The measurement of disability in low-income countries is recognised as a major deficiency in health information systems, especially in Africa. The Iganga and Mayuge Demographic Surveillance System (IM-DSS) in Uganda provides a special opportunity to develop population-based data to inform national health policies and evaluate innovations in assessing the burden of disability in Uganda. In this study, we apply a new instrument to screen for physical disabilities at the IM-DSS. The study utilised a modified version of the short set of questions proposed by the Washington Group on Disability Statistics. The instrument was applied at the household level and information was collected on all individuals over the age of 5, who were residents of the IM-DSS. The study was based at the IM-DSS, which covers the parts of Iganga and Mayuge districts in Eastern Uganda. 57,247 individuals were included in the survey, with 51% of the study population being women. Activity limitations The overall prevalence of physical disability at the IM-DSS was 9.4%, with vision being the most common type of difficulty reported in this population, and communication being least prevalent. Disability was less likely to be observed among males than their female counterparts (OR 0.75; 95% CI 0.71 to 0.81; pdisability and increasing age, as well as disability and decreasing household wealth status. This study shows that the modified short set of questions can be readily applied in a DSS setting to obtain estimates on the prevalence and types of disability at the population level. This instrument could be adapted for use to screen for disability in other LMIC settings, providing estimates that are comparable across different global regions and populations.

2014-01-01

Since the first criticality in March 1984, the Jamaica SLOWPOKE-2 research reactor at the University of the West Indies, Mona located in the department of the International Centre for Environmental and Nuclear Sciences (ICENS) has operated for approximately 52% of the lifetime of the existing core configuration. The 20kW pool type research reactor has been primarily used for neutron activation analysis in environmental, agricultural, geochemical, health-related studies and mineral exploration in Jamaica. The involvement of the JM-1 reactor for research and teaching activities has segued into commercial applications which, coupled with the current core conversion programme from HEU to LEU, has demanded the implementation of management systems to satisfy regulatory requirements and assure compliance with internationally defined quality standards. At ICENS, documentation related to the Quality Management System aspect of an Integrated Management System (IMS) is well underway. The quality system will incorporate operational and nuclear safety, training, maintenance, design, utilization, occupational health and safety, quality service, and environmental management for its Nuclear Analytical Laboratory, NAL. The IMS is being designed to meet the requirements of the IAEA GS-R-3 with additional controls from international standards including: ISO/IEC 17025:2005, ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007.

The paper summarizes the main findings of a scientific study. Accident figures for the German mining industry indicate that, in comparison with other industries, there is still plenty of scope for increased prevention. However, the rapid development of safety technology alone is still yielding diminishing returns. The main route to increased safety in the mining industry is by way of improved safety management. Various methods are available for analyzing the efficiency of work-safety structures and procedures. Models for the classification of safety-relevant tasks are based on the legally appropriate and organisationally expedient allocation of responsibilities between management and safety experts. An important management tool in this respect is the hazard analysis procedure laid down in the European Union's Health and Safety at Work Act. Practical studies are used to illustrate that safety results can be improved through reorganisation without increasing prime costs. (orig.) [German] Der Beitrag fasst die wesentlichen Ergebnisse einer wissenschaftlichen Studie zusammen: Die Unfallentwicklung im deutschen Bergbau zeigt im Vergleich zu anderen Industriezweigen noch deutliche Reserven fuer die Praevention. Die Fortentwicklung der Sicherheitstechnik fuer sich allein liefert aber nur noch abnehmende Grenzertraege. Eine Strategie technischer und organisatorischer Einzeldirektiven reicht ebenfalls nicht aus. Der Weg zu besseren Sicherheitsresultaten im Bergbau fuehrt vor allem ueber optimierte Ablaeufe des Sicherheitsmanagements. Mit verschiedenen Methoden lassen sich Aufbau- und Ablauforganisation der Arbeitssicherheit auf ihre Effizienz untersuchen. Aus der juristisch implizierten und organisatorisch zweckmaessigen Aufgabenteilung zwischen Fuehrungskraeften und Sicherheitsexperten ergeben sich Zurodnungsmuster fuer sicherheitsrelevante Aufgaben.

Seasonal fluctuations in solar radiation and vitamin D levels could modulate the immune response against Epstein-Barr virus (EBV) infection and influence the subsequent risk of multiple sclerosis (MS). Altogether 1660 MS patients and 3050 controls from Norway and Italy participating in the multinational case-control study of Environmental Factors In Multiple Sclerosis (EnvIMS) reported season of past infectious mononucleosis (IM). IM was generally reported more frequently in Norway (p=0.002), but was associated with MS to a similar degree in Norway (odds ratio (OR) 2.12, 95% confidence interval (CI) 1.64-2.73) and Italy (OR 1.72, 95% CI 1.17-2.52). For all participants, there was a higher reported frequency of IM during spring compared to fall (p<0.0005). Stratified by season of IM, the ORs for MS were 1.58 in spring (95% CI 1.08-2.31), 2.26 in summer (95% CI 1.46-3.51), 2.86 in fall (95% CI 1.69-4.85) and 2.30 in winter (95% CI 1.45-3.66). IM is associated with MS independently of season, and the association is not stronger for IM during spring, when vitamin D levels reach nadir. The distribution of IM may point towards a correlation with solar radiation or other factors with a similar latitudinal and seasonal variation.

General Purpose Data-Driven Online System Health Monitoring with Applications to Space Operations

Science.gov (United States)

Iverson, David L.; Spirkovska, Lilly; Schwabacher, Mark

2010-01-01

Modern space transportation and ground support system designs are becoming increasingly sophisticated and complex. Determining the health state of these systems using traditional parameter limit checking, or model-based or rule-based methods is becoming more difficult as the number of sensors and component interactions grows. Data-driven monitoring techniques have been developed to address these issues by analyzing system operations data to automatically characterize normal system behavior. System health can be monitored by comparing real-time operating data with these nominal characterizations, providing detection of anomalous data signatures indicative of system faults, failures, or precursors of significant failures. The Inductive Monitoring System (IMS) is a general purpose, data-driven system health monitoring software tool that has been successfully applied to several aerospace applications and is under evaluation for anomaly detection in vehicle and ground equipment for next generation launch systems. After an introduction to IMS application development, we discuss these NASA online monitoring applications, including the integration of IMS with complementary model-based and rule-based methods. Although the examples presented in this paper are from space operations applications, IMS is a general-purpose health-monitoring tool that is also applicable to power generation and transmission system monitoring.

Purification, crystallization and preliminary X-ray analysis of the aminoglycoside-6′-acetyltransferase AAC(6′)-Im

International Nuclear Information System (INIS)

Toth, Marta; Vakulenko, Sergei B.; Smith, Clyde A.

2012-01-01

AAC(6′)-Im is an N-acetyltransferase enzyme responsible for aminoglycoside resistance in E. faecium and E. coli isolates. Crystals of the kanamycin complex of this enzyme have been prepared and preliminary X-ray diffraction experiments have been undertaken. Bacterial resistance to the aminoglycoside antibiotics is primarily the result of enzymatic deactivation of the drugs. The aminoglycoside N-acetyltransferases (AACs) are a large family of bacterial enzymes that are responsible for coenzyme-A-facilitated acetylation of aminoglycosides. The gene encoding one of these enzymes, AAC(6′)-Im, has been cloned and the protein (comprising 178 amino-acid residues) was expressed in Escherichia coli, purified and crystallized as the kanamycin complex. Synchrotron diffraction data to approximately 2.0 Å resolution were collected from a crystal of this complex on beamline BL12-2 at SSRL (Stanford, California, USA). The crystals belonged to the hexagonal space group P6 5 , with approximate unit-cell parameters a = 107.75, c = 37.33 Å, and contained one molecule in the asymmetric unit. Structure determination is under way using molecular replacement

Full text: The design and implementation of an Integrated Management System at SNN SA Headquarters become necessary as the CNCAN norms are already under revision to comply with the IAEA GS-R-3 standard. The purpose of this analysis is to draft a project for the transition from a Quality Management System (QMS) to an Integrated Management System (IMS) complying with GS-R-3 requirements. Four steps were identified for developing this project: STEP1 - To justify the necessity of the IMS implementation to meet the SNN SA Headquarters Top Management commitments. The requirements for implementing an IMS are analyzed and a comprehensive document is issued to (and maybe discussed with) SNN General Director in order to obtain the top management adherence/commitment to the project implementation. The document will show the strong and the weak points which should be considered in developing the project. The references for the project are: - IAEA Safety Standard GS-R-3 'The Management System for Facilities and Activities'; - ISO - 1400/2004 Standard 'Environmental Management System Requirements'; - OHSAS 18001/2007 Standard 'Occupational Health and Safety Management Systems. Requirements'; There are also considered: - IAEA Safety Guide GS-G-3.1 'Application of the Management System for Facilities and Activities'; - IAEA Draft Safety Guide DS-349 'Application of the Management System for Nuclear Facilities; There will be considered: Workshop 2 Bookmarks (F5) 2 - CNCAN Norms (as they will be revised); STEP2 - The performance of a comparative analysis of the requirements of GS-R-3, ISO 14001 and OHSAS 18001 versus the provisions of the QMS already implemented in SNN. This analysis is shown as a comparative table; STEP3 - Identification of the IMS processes. An overall analysis of the current processes described in the SNN QMS Manual is performed and based on this. There are identified the additional processes that have to be documented for the proper implementation of an IMS

Spontane Mobilisierung und der Wandel kollektiver Formationen im Internet. Eine Fallstudie zur PEGIDA-Bewegung

Directory of Open Access Journals (Sweden)

Sang-hui Nam

2016-11-01

Full Text Available Der vorliegende Beitrag beschäftigt sich mit der Frage, wie sich eine aus spontaner Mobilisierung entstandene soziale Bewegung als kollektive Formation im Internet entwickelt. Da spontane Bewegungen in aller Regel nur über eine schwache kollektive Identität verfügen, werden sie bislang überwiegend als Übergangsphänomen betrachtet. Viele Studien beschäftigten sich eher mit den Folgen spontaner Mobilisierung, insbesondere der Frage, wie daraus eine nachhaltige Bewegung entstehen kann. Die kollektive Formation selbst ist bis dato weitgehend eine Blackbox geblieben. In der vorliegenden Studie widme ich mich folgenden zentralen Forschungsfragen: 1. Wie werden kollektive Formationen aus spontanen ProtestteilnehmerInnen dargestellt und generiert? 2. Wie ändern sich diese im Verlauf der Mobilisierung? Im Mittelpunkt der empirischen Analyse stehen Online-Kommentare, die eine zunehmend wichtige Rolle für soziale Bewegungen und spontane Mobilisierungsprozesse spielen. Am Beispiel von PEGIDA wird die Konstruktion einer kollektiven Formation über Live-Kommentare zu Live-Übertragungen von PEGIDA-Demonstrationen sowie deren Wandel in drei Phasen untersucht. Im ersten Schritt werden die soziotechnischen Grundlagen kollektiven Handelns im Internet erläutert. Der zweite Schritt befasst sich mit der methodischen Vorgehensweise. Im dritten Schritt werden ausgewählte Textpassagen von Online-Kommentaren analysiert. Anschließend wird der Wandel kollektiver Formationen nachgezeichnet.

A new ppb-gas analyzer by means of GC-ion mobility spectrometry (GC-IMS)

International Nuclear Information System (INIS)

Leonhardt, J.W.

2003-01-01

IMS-detectors are using beta-sources like tritium or nickel-63. This detection principle uses fast ion-molecular reactions between air cluster ions, produced by beta ionization and the analyte. The system works at normal pressure, the very high sensitivity and selectivity is used widely in industry, research, medicine and environmental control. In the last few years especially, small tritium sources were reduced to a level of some 50 MBq, which is 20 times less than the exemption levels for these sources. One of the handicaps of that technology is the problem of cross sensitivities. To overcome these problems a special GC-column of 1 m length has been included into the gas inlet and mixtures of compounds get separated by their retention times before entering the drift sensor. By means of that method a new analytical quality of IMS is arrived. The application of these analytical devices got a spin off in the last year. The main applications being discussed are as follows: (1) anti terror systems in buildings and facilities, (2) working place monitoring in chemical industry, (3) microelectronics: HF, HCl, Cl 2 , NMP, NH 3 , NO 2 , SO 2 , (4) environment: NH 3 , HCN, HCl, CH 2 O, organic compounds, SO 2 , NO 2 , (5) gas and petrol: gas-carottage, H 2 S, mercaptans, (6) household, furniture: solvents, clue, organic vapour from furniture, and (7) health care: diagnostics of various diseases.

A plan for location calibration of IMS stations and near Kazakhstan

International Nuclear Information System (INIS)

Richards, P.G.; Kim, W.-Yo.; Khalturin, V.I.

2001-01-01

For purposes of monitoring compliance with the Comprehensive Nuclear Test-Ban Treaty, it is desirable to be able to locate seismic events routinely to within an uncertainty not greater than 1000 square km. From more than five years of experience with publication of the Reviewed Event Bulletin (REB) by the Prototype International Data Centre (PIDC), resulting in estimated locations for more than 100,000 seismic events, it is apparent that improved location accuracy is needed in order to reduce uncertainties below 1000 square km. In this paper, we outline a three-year program of applied research which commenced in March 2000 and which has the goal of achieving improved REB locations based upon data to be contributed to the International Data Centre from 30 IMS stations in Eastern Asia. Our first efforts will focus on the four IMS seismographic stations in Kazakhstan (AKT, BRV, KUR, MAK), together with IMS stations ZAL in Russia and AAK in Kyrgyzstan. Following the recommendations of two 'IMS Location Calibration Workshops' held in Oslo, Norway, in 1999 and 2000, our approach is to generate station-specific travel times for each observable seismic phase, as a function of distance and azimuth (and depth, where possible). Such travel times are obtained on the basis of (i) early studies based mainly on earthquake data (e.g. Nersesov and Rautian, 1964), (ii) Deep Seismic Sounding, and (iii) recent studies of nuclear and chemical explosions. We are also using (iv) an empirical approach in which phases are picked at IMS stations, for so-called Ground Truth events whose location is known quite accurately on the basis of additional data, obtained for example from local and regional networks.

Peirano, Daniel J; Pasamontes, Alberto; Davis, Cristina E

2016-09-01

Modern differential mobility spectrometers (DMS) produce complex and multi-dimensional data streams that allow for near-real-time or post-hoc chemical detection for a variety of applications. An active area of interest for this technology is metabolite monitoring for biological applications, and these data sets regularly have unique technical and data analysis end user requirements. While there are initial publications on how investigators have individually processed and analyzed their DMS metabolomic data, there are no user-ready commercial or open source software packages that are easily used for this purpose. We have created custom software uniquely suited to analyze gas chromatograph / differential mobility spectrometry (GC/DMS) data from biological sources. Here we explain the implementation of the software, describe the user features that are available, and provide an example of how this software functions using a previously-published data set. The software is compatible with many commercial or home-made DMS systems. Because the software is versatile, it can also potentially be used for other similarly structured data sets, such as GC/GC and other IMS modalities.

Socio-cultural differences for country-specific activities are rarely addressed in physical activity questionnaires. We examined the reliability and validity of the Indian Migration Study Physical Activity Questionnaire (IMS-PAQ) in urban and rural groups in India. A sub-sample of IMS participants (n = 479) was used to examine short term (≤ 1 month [n = 158]) and long term (> 1 month [n = 321]) IMS-PAQ reliability for levels of total, sedentary, light and moderate/vigorous activity (MVPA) intensity using intraclass correlation (ICC) and kappa coefficients (k). Criterion validity (n = 157) was examined by comparing the IMS-PAQ to a uniaxial accelerometer (ACC) worn ≥ 4 days, via Spearman's rank correlations (ρ) and k, using Bland-Altman plots to check for systematic bias. Construct validity (n = 7,000) was established using linear regression, comparing IMS-PAQ against theoretical constructs associated with physical activity (PA): BMI [kg/m2], percent body fat and pulse rate. IMS-PAQ reliability ranged from ICC 0.42-0.88 and k = 0.37-0.61 (≤ 1 month) and ICC 0.26 to 0.62; kappa 0.17 to 0.45 (> 1 month). Criterion validity was ρ = 0.18-0.48; k = 0.08-0.34. Light activity was underestimated and MVPA consistently and substantially overestimated for the IMS-PAQ vs. the accelerometer. Criterion validity was moderate for total activity and MVPA. Reliability and validity were comparable for urban and rural participants but lower in women than men. Increasing time spent in total activity or MVPA, and decreasing time in sedentary activity were associated with decreasing BMI, percent body fat and pulse rate, thereby demonstrating construct validity. IMS-PAQ reliability and validity is similar to comparable self-reported instruments. It is an appropriate tool for ranking PA of individuals in India. Some refinements may be required for sedentary populations and women in India.

Background and Purpose The IMS III study tested the effect of IV t-PA alone as compared to IV t-PA followed by endovascular therapy and collected cost data to assess the economic implications of the two therapies. This report describes the factors affecting the costs of the initial hospitalization for acute stroke subjects from the US. Methods Prospective cost analysis of US subjects treated with IV t-PA alone or IV t-PA followed by endovascular therapy in the IMS III trial. Results compared to expected Medicare payments. Results The adjusted cost of a stroke admission in the study was $35,130 for subjects treated with endovascular therapy following IV t-PA treatment and $25,630 for subjects treated with IV t-PA alone (p<0.0001). Significant factors related to costs included treatment group, baseline NIH Stroke Scale, time from stroke onset to IV t-PA, age, stroke location, and comorbid diabetes. The mean cost for subjects who had routine use of general anesthesia as part of endovascular therapy was $46,444 as compared to $30,350 for those who did not have general anesthesia. The costs of embolectomy for IMS III subjects and patients from the NIS cohort exceeded the Medicare DRG payment in more than 75% of patients. Conclusion Minimizing the time to start of IV t-PA and decreasing the use of routine general anesthesia, may improve the cost-effectiveness of medical and endovascular therapy for acute stroke.

A {sup 13}C{sup {alpha}} chemical exchange saturation transfer based experiment is presented for the study of protein systems undergoing slow interconversion between an 'observable' ground state and one or more 'invisible' excited states. Here a labeling strategy whereby [2-{sup 13}C]-glucose is the sole carbon source is exploited, producing proteins with {sup 13}C at the C{sup {alpha}} position, while the majority of residues remain unlabeled at CO or C{sup {beta}}. The new experiment is demonstrated with an application to the folding reaction of the Im7 protein that involves an on-pathway excited state. The obtained excited state {sup 13}C{sup {alpha}} chemical shifts are cross validated by comparison to values extracted from analysis of CPMG relaxation dispersion profiles, establishing the utility of the methodology.

Full Text Available Abstract Background Socio-cultural differences for country-specific activities are rarely addressed in physical activity questionnaires. We examined the reliability and validity of the Indian Migration Study Physical Activity Questionnaire (IMS-PAQ in urban and rural groups in India. Methods A sub-sample of IMS participants (n = 479 was used to examine short term (≤1 month [n = 158] and long term (> 1 month [n = 321] IMS-PAQ reliability for levels of total, sedentary, light and moderate/vigorous activity (MVPA intensity using intraclass correlation (ICC and kappa coefficients (k. Criterion validity (n = 157 was examined by comparing the IMS-PAQ to a uniaxial accelerometer (ACC worn ≥4 days, via Spearman's rank correlations (ρ and k, using Bland-Altman plots to check for systematic bias. Construct validity (n = 7,000 was established using linear regression, comparing IMS-PAQ against theoretical constructs associated with physical activity (PA: BMI [kg/m2], percent body fat and pulse rate. Results IMS-PAQ reliability ranged from ICC 0.42-0.88 and k = 0.37-0.61 (≤1 month and ICC 0.26 to 0.62; kappa 0.17 to 0.45 (> 1 month. Criterion validity was ρ = 0.18-0.48; k = 0.08-0.34. Light activity was underestimated and MVPA consistently and substantially overestimated for the IMS-PAQ vs. the accelerometer. Criterion validity was moderate for total activity and MVPA. Reliability and validity were comparable for urban and rural participants but lower in women than men. Increasing time spent in total activity or MVPA, and decreasing time in sedentary activity were associated with decreasing BMI, percent body fat and pulse rate, thereby demonstrating construct validity. Conclusion IMS-PAQ reliability and validity is similar to comparable self-reported instruments. It is an appropriate tool for ranking PA of individuals in India. Some refinements may be required for sedentary populations and women in India.

An intermodal approach for the evaluation of transportation services on the municipal level was developed. Both non-motorised and motorised transportation were included. The approach aims at helping communities to provide an economically and ecologically viable transport policy. Least Cost Transportation Planning (LCTP) was developed to transfer the successful concept of Least Cost Planning from the energy sector to transportation. The conclusion from an analysis of LCTP literature and present evaluation methods was that an improved approach should be intermodal and integrate users, public bodies and transport companies as well as all planning sectors. An approach was developed firstly to identify and clarify transportation expenditures and incomes of a city within a year, and secondly for the evaluation of planning alternatives. This was illustrated for the access system of an industrial area with adjacent railway services in the town of Freiburg. Three alternatives were compared: the extension of a tramway line, the upgrading of the present bus system, and the development of a service and bicycle provision concept for rail stations and companies. Besides income and expenditure for each alternative, the effects on transport demand, the impact on air pollution and noise and on space consumption were presented. As a result, the bicycle concept is in most items better than its alternatives. The final report has three volumes and there is an extra guideline for implementing the method within municipalities. It includes a set of excel sheet tables for an easy application (all in German). (orig.)

An IMS-Based Middleware Solution for Energy-Efficient and Cost-Effective Mobile Multimedia Services

Science.gov (United States)

Bellavista, Paolo; Corradi, Antonio; Foschini, Luca

Mobile multimedia services have recently become of extreme industrial relevance due to the advances in both wireless client devices and multimedia communications. That has motivated important standardization efforts, such as the IP Multimedia Subsystem (IMS) to support session control, mobility, and interoperability in all-IP next generation networks. Notwithstanding the central role of IMS in novel mobile multimedia, the potential of IMS-based service composition for the development of new classes of ready-to-use, energy-efficient, and cost-effective services is still widely unexplored. The paper proposes an original solution for the dynamic and standard-compliant redirection of incoming voice calls towards WiFi-equipped smart phones. The primary design guideline is to reduce energy consumption and service costs for the final user by automatically switching from the 3G to the WiFi infrastructure whenever possible. The proposal is fully compliant with the IMS standard and exploits the recently released IMS presence service to update device location and current communication opportunities. The reported experimental results point out that our solution, in a simple way and with full compliance with state-of-the-art industrially-accepted standards, can significantly increase battery lifetime without negative effects on call initiation delay.

Large sample neutron activation analysis (LSNAA) work was carried out for samples of coal, uranium ore, stainless steel, ancient and new clay potteries, dross and clay pottery replica from Peru using low flux high thermalized irradiation sites. Large as well as non-standard geometry samples (1 g - 0.5 kg) were irradiated using thermal column (TC) facility of Apsara reactor as well as graphite reflector position of critical facility (CF) at Bhabha Atomic Research Centre, Mumbai. Small size (10 - 500 mg) samples were also irradiated at core position of Apsara reactor, pneumatic carrier facility (PCF) of Dhruva reactor and pneumatic fast transfer facility (PFTS) of KAMINI reactor. Irradiation positions were characterized using indium flux monitor for TC and CF whereas multi monitors were used at other positions. Radioactive assay was carried out using high resolution gamma ray spectrometry. The k0-based internal monostandard NAA (IM-NAA) method was used to determine elemental concentration ratios with respect to Na in coal and uranium ore samples, Sc in pottery samples and Fe in stainless steel. Insitu relative detection efficiency for each irradiated sample was obtained using γ rays of activation products in the required energy range. Representative sample sizes were arrived at for coal and uranium ore from the plots of La/Na ratios as a function of the mass of the sample. For stainless steel sample of SS 304L, the absolute concentrations were calculated from concentration ratios by mass balance approach since all the major elements (Fe, Cr, Ni and Mn) were amenable to NAA. Concentration ratios obtained by IM-NAA were used for provenance study of 30 clay potteries, obtained from excavated Buddhist sites of AP, India. The La to Ce concentration ratios were used for preliminary grouping and concentration ratios of 15 elements with respect to Sc were used by statistical cluster analysis for confirmation of grouping. Concentrations of Au and Ag were determined in not so

Today, modelling and simulation of traffic flow is used for the design and investigation of new systems, in particular for driver assistance and especially for on-line applications for the reconstruction of traffic state. In the project existing software tools were improved, refined and adapted for special applications in the joined project MoTiV. An emphasis was the development, provision and application of robust techniques for the traffic state estimation at existing line control equipment, where measured traffic data have been used as input. A further emphasis was the development of a model for the traffic in urban areas and the application of this model for the design and optimisation of co-ordinated control of light signal units. In this application modern control techniques and also agent-based techniques were used. Significant results are the design of controllers for ACC systems, the sensor simulations for the project ASA (turning and lane changing assistance) and the methods of the model coupling for applications of the incident detection. A highlight was the on-line application of different methods and techniques for the reconstruction of speed and density profiles and the tools for the incident detection in the context of the COMPANION system which was installed at the German highway A92. For the final demonstration in Goettingen, single vehicle data were collected with help of induction loops at the test site A92. These data were transmitted to the demonstration site, where the processing and visualisation was conducted. To get a good visual impression about the traffic states and to compare the results, a transmission of video images was transmitted parallel to the traffic data. (orig.)

The present study addresses the topic of sustainable design, construction and living in the information age. The focus - according to the institute's fields of activity and competence - rests on the contribution of information and automation technology. The study is based on extensive inquiries and brings together the experience of the authors and preliminary investigations results. Its objective is to analyse state of the art technology, trends and to then draw conclusions for our own R and D projects. The general conditions for future ''building and living'' are presented under the aspect of sustainability. Admittedly, important problems of the social, economic and ecological dimensions of sustainable ''building and living'' are only touched within the scope of this study. The analysis of the state of the art concentrates on three fields, the application of information technology in the design phase, the automated manufacturing and construction and home automation. Generally, it can be stated that information and automation technology bears great potential for innovations in the area of ''building and living''. Main trends in the field of design include the development of product model standards and the use of digital building models in all phases of the life cycle. In the field of manufacturing an orientation towards utilization of prefabricated building components, which can be produced on automated facilities, is observed. The field of home automation is characterized by very dynamic development. Emphasis lies on the informational integration of all technical appliances in the home and the development of new services and functionality on this basis. Starting from this analysis our own R and D activities are proposed within a common frame formed by the vision of the FZK house. These activities comprise investigations and development of a product model for the FZK house, for a factory producing

We study the quantum spectral curve of the Argyres-Douglas theories in the Nekrasov-Sahashvili limit of the Omega-background. Using the ODE/IM correspondence we investigate the quantum integrable model corresponding to the quantum spectral curve. We show that the models for the A 2 N -type theories are non-unitary coset models ( A 1)1 × ( A 1) L /( A 1) L+1 at the fractional level L=2/2N+1-2 , which appear in the study of the 4d/2d correspondence of N = 2 superconformal field theories. Based on the WKB analysis, we clarify the relation between the Y-functions and the quantum periods and study the exact Bohr-Sommerfeld quantization condition for the quantum periods. We also discuss the quantum spectral curves for the D and E type theories.

After full replacement of the feedwater pipe system during the inspection period in 1997, combined with a modern materials, manufacturing and analysis concept, the entire pipe system of the water/steam cycle in the reactor building of KKP 1 now consists of high-toughness materials. The safety level of the entire plant has been increased by leaving aside postulation of F2 breaks in the reactor building and providing for protection against 0.1 leaks. Based on fluid-dynamic calculations for the cases of pump failure and pipe break, as well as pipe system calculations in 5 extensive calculation cycles, about 130 documents were filed for inspection and approval (excluding preliminary test documents on restraints). Points of main interest for safety analysis in this context were the optimised closing performance of the 3rd check valves and the integrity of the nozzle region at the RPV. (oirg./CB) [Deutsch] Durch den Restaustausch der Speisewasserleitungen in der Revision 1997, verbunden mit einem modernen Werkstoff-, Fertigungs- und Nachweiskonzept, sind im Reaktorgebaeude von KKP 1 in den Hauptleitungen des Wasser-Dampf-Kreislaufes nur noch hochzaehe Werkstoffe eingesetzt. Durch den Verzicht auf das Postulat von 2F-Bruechen im Reaktorgebaeude und durch die Auslegung gegen 0,1F-Lecks wird das Sicherheitsniveau der Anlage insgesamt gesteigert. Ausgehend von fluiddynamischen Berechnungen fuer Pumpenausfall und Rohrbruch sowie Rohrsystem-Berechnungen in 5 umfangreichen Berechnungskreisen wurden fuer die Genehmigung und Begutachtung ca. 130 Unterlagen (ohne Halterungs-Vorpruefunterlagen) eingereicht und vom Gutachter geprueft. Schwerpunkte der Nachweisfuehrung waren die Optimierung des Schliessverhaltens der 3. Rueckschlagarmaturen sowie der Integritaetsnachweis des RDB-Anschlusses. (orig./MM)

Aim of the study: Is it possible to use the Internet as a secure media for transport of telemedicine? Which risks exist for routine use? In this article state of the art methods of security were analysed. Telemedicine in the Internet has severe risks, because patient data and hospital data of a secure Intranet can be manipulated by connecting it to the Web. Conclusions: Establishing of a firewall and the introduction of HPC (Health Professional Card) are minimizing the risk of un-authorized access to the hospital server. HPC allows good safety with digital signature and authentication of host and client of medical data. For secure e-mail PGP (Pretty Good Privacy) is easy to use as a standard protocol. Planning all activities exactly as well as following legal regulations are important requisites for reduction of safety risks in Internet. (orig.) [German] Ziele der Studie und Analyse: Es sollten die Fragen beantwortet werden, ob es moeglich ist, das Internet als sicheres Uebermittlungsmedium fuer Telemedizin zu nutzen und welche Sicherheitsrisiken bestehen. Dazu wurden die gaengigen Sicherheitsmethoden analysiert. Telemedizin im Internet ist mit Sicherheitsrisiken behaftet, die durch die Oeffnung eines Intranets mit der Moeglichkeit zur unberechtigten Manipulation von aussen bedingt sind. Schlussfolgerung: Diese Sicherheitsrisiken koennen durch eine Firewall weitgehend unterbunden werden. Chipkarten wie die Health professional card ermoeglichen eine hohe Sicherheit bei digitaler Signatur und sicherer Authentifikation der Sender und Empfaenger von Daten im Internet. Auch Standards wie Pretty good privacy sind inzwischen fuer sichere e-mails einfach einzusetzen. Wichtige Voraussetzung fuer die Reduktion von Sicherheitsrisiken ist unter Beruecksichtigung der gesetzlichen Vorgaben die exakte Planung aller Aktivitaeten im Internet, bei denen medizinische Patientendaten versandt werden sollen, in einem Team aus Aerzten und Informatikern.

Full Text Available La medicina moderna es una actividad cada vez más compleja, basada en la información proveniente de múltiples fuentes: historias clínicas, dictáfonos e imágenes y vídeos provenientes de múltiples dispositivos. Las imágenes médicas constituyen una de las fuentes de mayor importancia, por cuanto ofrecen un apoyo integral del acto médico: el diagnóstico y el seguimiento. Sin embargo, la cantidad de información generada por los dispositivos de adquisición de imágenes sobrepasa rápidamente la disponibilidad de almacenamiento que tienen los servicios de radiología, lo cual genera costos adicionales en equipos de cómputo con mayor capacidad de almacenamiento. Además, la tendencia actual de desarrollo de aplicaciones en la “nube de cómputo”, tiene limitaciones por cuanto, aunque el almacenamiento es virtual y está disponible desde cualquier sitio, la conexión se hace a través de internet. En estos dos casos, el uso óptimo de la información requiere necesariamente de algoritmos de compresión potentes y adaptados a las necesidades de la actividad médica. En este artículo se presenta una revisión de las técnicas de compresión más utilizadas para el almacenamiento de imágenes, así como un análisis crítico de éstas desde el punto de vista de su uso en ambientes clínicos.   doi: http://dx.doi.org/10.7705/biomedica.v33i1.804

The Applicability of Incoherent Array Processing to IMS Seismic Array Stations

Gibbons, S. J.

nuclear tests but, due to signal incoherence, failed to contribute to the automatic event detections. It is demonstrated that the smoothed incoherent slowness estimates for the MJAR Pn phases for both tests indicate unambiguously the correct type of phase and a backazimuth estimate within 5 degrees of the great-circle backazimuth. The detection part of the algorithm is applicable to all IMS arrays, and spectrogram-based processing may offer a reduction in the false alarm rate for high frequency signals. Significantly, the local maxima of the scalar functions derived from the transformed spectrogram beams provide good estimates of the signal onset time. High frequency energy is of greater significance for lower event magnitudes and in, for example, the cavity decoupling detection evasion scenario. There is a need to characterize propagation paths with low attenuation of high frequency energy and situations in which parameter estimation on array stations fails.

Surface characterization of IM7/5260 composites by x-ray photoelectron spectroscopy

International Nuclear Information System (INIS)

Ohno, Satomi; Lee, Moon-Hwan; Lin, Kuen Y.; Ohuchi, Fumio S.

2001-01-01

Surfaces of high-performance carbon fiber/bismeleimide (BMI) composites (IM7/5260) have been characterized by x-ray photoelectron spectroscopy. An experimental technique to separately examine the chemical natures of the carbon fibers and BMI resin in the composite form was developed. This technique uses a flood gun to establish differential charging conditions on the BMI resin. The binding energies from the BMI resin were shifted by an amount of voltage applied to the flood gun, whereas those from the carbon fibers were uniquely determined due to their electrically conducting nature. By adding external bias voltage to the sample, the binding energies for conducting fibers were further shifted from those of the BMI resin, thereby separating the IM7 phase completely from the BMI phase in the binding energy scale, allowing independent measurement of the chemical changes associated with those peaks. Using this technique, the effects of thermal aging and surface plasma treatment on the IM7/5260 composite were studied

Methods Eighteen-day-old broiler embryos were injected with 100 μL of phosphate-buffered saline, profilin, profilin plus necrotic enteritis B-like (NetB, profilin plus NetB/Montanide adjuvant (IMS 106, and profilin plus Net-B/Montanide adjuvant (IMS 101. After post-hatch birds were challenged with our NE experimental disease model, body weights, intestinal lesions, serum antibody levels to NetB, and proinflammatory cytokine and chemokine mRNA levels in intestinal intraepithelial lymphocytes were measured. Results Chickens in ovo vaccinated with recombinant profilin plus NetB proteins/IMS106 and recombinant profilin plus NetB proteins/IMS101 showed significantly increased body weight gains and reduced gut damages compared with the profilin-only group, respectively. Greater antibody response to NetB toxin were observed in the profilin plus NetB/IMS 106, and profilin plus NetB/IMS 101 groups compared with the other three vaccine/adjuvant groups. Finally, diminished levels of transcripts encoding for proinflammatory cytokines such as lipopolysaccharide-induced tumor necrosis factor-α factor, tumor necrosis factor superfamily 15, and interleukin-8 were observed in the intestinal lymphocytes of chickens in ovo injected with profilin plus NetB toxin in combination with IMS 106, and profilin plus NetB toxin in combination with IMS 101 compared with profilin protein alone bird.

Imaging mass spectrometry (IMS) is a molecular imaging technology that can measure thousands of biomolecules concurrently without prior tagging, making it particularly suitable for exploratory research. However, the data size and dimensionality often makes thorough extraction of relevant information impractical. To help guide and accelerate IMS data analysis, we recently developed a framework that integrates IMS measurements with anatomical atlases, opening up opportunities for anatomy-driven exploration of IMS data. One example is the automated anatomical interpretation of ion images, where empirically measured ion distributions are automatically decomposed into their underlying anatomical structures. While offering significant potential, IMS-atlas integration has thus far been restricted to the Allen Mouse Brain Atlas (AMBA) and mouse brain samples. Here, we expand the applicability of this framework by extending towards new animal species and a new set of anatomical atlases retrieved from the Scalable Brain Atlas (SBA). Furthermore, as many SBA atlases are based on magnetic resonance imaging (MRI) data, a new registration pipeline was developed that enables direct non-rigid IMS-to-MRI registration. These developments are demonstrated on protein-focused FTICR IMS measurements from coronal brain sections of a Parkinson's disease (PD) rat model. The measurements are integrated with an MRI-based rat brain atlas from the SBA. The new rat-focused IMS-atlas integration is used to perform automated anatomical interpretation and to find differential ions between healthy and diseased tissue. IMS-atlas integration can serve as an important accelerator in IMS data exploration, and with these new developments it can now be applied to a wider variety of animal species and modalities.

2017-01-01

Optical wireless communications (OWC) is a promising technology for closing the mismatch between the growing number of connected devices and the limited wireless network capabilities. Similar to downlink, uplink can also benefit from OWC for establishing connectivity between such devices and an optical access point. In this context, the incoherent intensitymodulation and direct-detection (IM-DD) scheme is desirable in practice. Hence, it is important to understand the fundamental limits of communication rates over an OWC uplink employing IM-DD, i.e., the channel capacity. This uplink, modeled as a Gaussian multiple-access channel (MAC) for indoors OWC, is studied in this paper, under the IM-DD constraints which form the main difference with the standard Gaussian MAC commonly studied in the radio-frequency context. Capacity region outer and inner bounds for this channel are derived. The bounds are fairly close at high signal-to-noise ratio (SNR), where a truncated- Gaussian input distribution achieves the capacity region within a constant gap. Furthermore, the bounds coincide at low SNR showing the optimality of on-off keying combined with successive cancellation decoding in this regime. At moderate SNR, an optimized uniformly-spaced discrete input distribution achieves fairly good performance.

Detection capability of the IMS seismic network based on ambient seismic noise measurements

Gaebler, Peter J.; Ceranna, Lars

2016-04-01

All nuclear explosions - on the Earth's surface, underground, underwater or in the atmosphere - are banned by the Comprehensive Nuclear-Test-Ban Treaty (CTBT). As part of this treaty, a verification regime was put into place to detect, locate and characterize nuclear explosion testings at any time, by anyone and everywhere on the Earth. The International Monitoring System (IMS) plays a key role in the verification regime of the CTBT. Out of the different monitoring techniques used in the IMS, the seismic waveform approach is the most effective technology for monitoring nuclear underground testing and to identify and characterize potential nuclear events. This study introduces a method of seismic threshold monitoring to assess an upper magnitude limit of a potential seismic event in a certain given geographical region. The method is based on ambient seismic background noise measurements at the individual IMS seismic stations as well as on global distance correction terms for body wave magnitudes, which are calculated using the seismic reflectivity method. From our investigations we conclude that a global detection threshold of around mb 4.0 can be achieved using only stations from the primary seismic network, a clear latitudinal dependence for the detection threshold can be observed between northern and southern hemisphere. Including the seismic stations being part of the auxiliary seismic IMS network results in a slight improvement of global detection capability. However, including wave arrivals from distances greater than 120 degrees, mainly PKP-wave arrivals, leads to a significant improvement in average global detection capability. In special this leads to an improvement of the detection threshold on the southern hemisphere. We further investigate the dependence of the detection capability on spatial (latitude and longitude) and temporal (time) parameters, as well as on parameters such as source type and percentage of operational IMS stations.

The newest version SIMPRO-IMS has recently been developed to support a need of integration of management systems and information archiving. With the last development, SIMPRO-IMS web based environment, processes of five ISO systems are integrated for parallel development, implementation, auditing, maintaining and leading. SIMPRO-IMS provides management with the apparatus necessary to realize a systematic and verifiable approach to the creation and control of IMS documentation. At the same time contributes to the preservation of organization memory in response to the growing challenges of globalization and digitalization. The research is limited by the complexity of a real system and possible empiric results verification. The results achieved are verified when people really overcome the resistance to change. This can be assessed thoughtfully only after some period of time. Another limitation is presented by measurability of real enhancement achieved in quality, safety and environmentality of production, and business continuity and social responsibility of an organization. Development and progress in the methodology of SIMPRO-IMS web based environment is encoded in upgrading the SIMPRO database by processes of the environmental management

Doing religion im Phowa-Kurs: Praxeologische und reflexionslogische Studien zum "bewussten Sterben" im Diamantweg-Buddhismus

Full Text Available Im Sinne einer pragmatistischen Perspektive, wie sie zuerst John DEWEY (1987 [1934] in Anschluss an William JAMES formulierte, ist das Religiöse weniger als eine spezifische Art von experience zu verstehen, denn als ein adjustment hin zu einer epistemischen Perspektive, die alle Erfahrungen in einem veränderten Licht erscheinen lässt. Religiosität zielt damit auf ein besonderes Selbst- und Weltverhältnis, in dem die Beziehung zwischen Selbst und Welt aus einer ganzheitlichen Perspektive betrachtet wird. Wie aber können fremde, auf den ersten Blick in ihrer Genese unwahrscheinliche und unter modernen Verhältnissen zudem anzweifelbare religiöse Haltungen und Sinnsysteme etabliert werden? Am Beispiel der im tibetischen Buddhismus verbreiteten Phowa-Meditation des "bewussten Sterbens" wird untersucht, wie für westliche Adept/innen auf den ersten Blick befremdlich und esoterisch anmutende spirituelle Lehren mit zunehmender Praxis an Evidenz und Sinnhaftigkeit gewinnen können, indem sich Gruppenprozesse, Visualisierungen, körperorientierte Übungen und psychisches Erleben zu einem übergreifenden Arrangement verschränken. Die empirische Datengrundlage für die Untersuchung liefern narrative Interviews mit westlich sozialisierten Schüler/innen und Lehrer/innen des Diamantweg-Buddhismus, der derzeit größten buddhistischen Gemeinschaft des tibetischen Buddhismus in Deutschland. Die Auswertung der Interviews erfolgte angelehnt an die dokumentarische Methode, erweitert durch eine Kontexturanalyse, um den Reflexionsverhältnissen gerecht zu werden, die den religiösen Selbst- und Weltbezug aufspannen.

Full Text Available [english] For more than 20 years teaching in the medical program at Witten/Herdecke Private University has followed the goal of introducing students to the reality of patient care by a practical approach. The “adaptive physician personality” describes the educational objective of a physician who is able to orient towards “the full spectrum” of his professional core competencies. In regard to the “adaptive physician personality” four Integrated Curricula (Communication, Science, Ethics, and Health Economy had been developed along with the introduction of a model medical program in 2000. Witten/Herdecke University thereby today addresses the requirements defined by the New Medical Licensure Act of 27.06.2002 and brings forward at the same time a program which prepares the medical student for the multi-dimensional responsibilities in the reality of modern health care. This article describes the Integrated Curricula exemplified by the Communication curriculum. This relatively young area of medical teaching in Germany is still extensively unexplored concerning evidence-based research about its effectiveness and efficiency of teaching.

Full Text Available La eliminación del ruido impulsivo es un problema clásico del procesado no lineal para el mejoramiento de imágenes y las funciones de base radial de soporte global son útiles para enfrentarlo. Este trabajo presenta una técnica de interpolación que disminuye eficientemente el ruido impulsivo en imágenes, mediante el uso de interpolante obtenido por funciones de base radial en el marco de la investigación enfocada en el desarrollo de un Sistema de recuperación de imágenes de recursos acuáticos amazónicos. Esta técnica primero etiqueta los píxeles de la imagen que son ruidosos y, mediante la interpolación, genera un valor de reconstrucción de dicho píxel usando sus vecinos. Los resultados obtenidos son comparables y muchas veces mejores que otras técnicas ya publicadas y reconocidas. Según el análisis de resultados, se puede aplicar a imágenes con altas tasas de ruido, manteniendo un bajo error de reconstrucción de los píxeles "ruidosos", así como la calidad visual.Global support radial base functions are effective in eliminating impulsive noise in non-linear processing. This paper introduces an interpolation technique which efficiently reduces image impulsive noise by means of an interpolant obtained through radial base functions. These functions have been used in a research project designed to develop a system for the recovery of images of Amazonian aquatic resources. This technique starts with the tagging by interpolation of noisy image pixels. Thus, a value of reconstruction for the noisy pixels is generated using neighboring pixels. The results obtained with this technique have proved comparable and often better than those obtained with previously known techniques. According to results analysis, this technique can be successfully applied on images with high noise levels. The results are low error in noisy pixel reconstruction and better visual quality.

Full Text Available Hatte man in den Neunzigerjahren das Netz vor allem als virtuelle Realität charakterisiert, das dem realen Alltag gegenübersteht, so wird immer stärker deutlich, wie stark die Kultur der alltäglichen Lebenswelt mit dem Kulturraum Internet verflochten ist. So wird das Netz, wo man online einkauft, Freunde im Chat trifft, sich täglich über aktuelle Nachrichten informiert, immer mehr als Erweiterung des alltäglichen Lebens betrachtet. Dies bedeutet daher auch, dass wer am Netz aktiv partizipiert, zugleich über einen Anteil an gesellschaftlicher Macht verfügt. Politische Kampagnen im Internet oder die Präsentation von Politikern/-innen bei Wahlkämpfen im Netz unterstreichen diesen Trend auf eindrückliche Weise. Damit ist das Internet ist in den letzten Jahren zu einem Kulturraum sui generis avanciert.

Zur Palökologie der Euproopiden im Nordwestdeutschen Oberkarbon

Full Text Available Tierische Fossilien aus dem Westfal D des Piesbergs bei Osnabrück sind seit 1860 vereinzelt immer wieder beschrieben worden. Doch erst durch die Funde der letzten 30 Jahre zählt der Piesberg zu den bedeutendsten Fundorten terrestrischer Fauna im Karbon. Erstmals werden 45 stratifiziert aufgesammelte Individuen von Euproops untersucht. Einige Details der Morphologie sowie eine dichte Behaarung werden beschrieben. Auf der Basis dieser Merkmale sowie der Verteilung juveniler und adulter Individuen im geologischen Profil wird eine Deutung des Lebensraumes der Euproopiden versucht. Danach hielten sich die juvenilen Individuen dieser Tiergruppe als Laubstreubewohner in feuchten Spülsäumen flacher ruhiger Gewässer und Laubstreuhorizonten auf. Die adulten Formen lebten vornehmlich benthisch in ufernahen Gewässern und verließen wohl nur noch gelegentlich das Wasser. Since 1860 articulated fossils of terrestrial taxa have been described from lower Westfalian D sediments of the Piesberg section near Osnabrück (northwestern Germany. In this paper 45 individuals of the genus Euproops, sampled from particular levels in the profile, are reported on for the first time. Analysis of the fossil material reveals new morphological details – especially setae densely covering the ventral side – that, combined with the geological setting of the profile, gives novel insights into the palaeoenvironment and to the hypothesis of subaerial activity. Young individuals of Euproops may have been "litter dwellers" inhabiting forest-litter and partly decayed plant material that had washed ashore. By contrast, adults formed a principal component of the nearshore benthic fauna. They were able to leave the water, but only for short periods. This is proved by the occurence of adults and juveniles in different lithologies. doi:10.1002/mmng.20000030105

Within the framework of an inventory of possible sites for hydroelectric power plants in the larger Hannover area, 60 sites in the rural district of Hannover were more closely investigated. 57 of these were former water mills and 3 were hydraulic structures that have nothing to do with former water mills. 29 water mills are to be considered as dismantled in hydraulic engineering terms, 8 are in operation, and 20 are decommissioned. Furthermore, 2 weirs and 1 barrage were included in the investigation.- In the area of the city of Hannover, there are four more sites of hydroelectric power plants, of which one is dismantled, two are decommissioned and one is in operation.- In order to complement the inventory, object expertises of different depths were prepared for eight selected sites. They permit a qualified assessment of the chances of reactivation of each site, taking the respective specific conditions into account. At the same time, they represent a first step towards detailed advice for a prospective operator (orig.).

Following the implementation of the National Cancer Prevention and Control Results-based Budget Programme (PpR Cancer-024) in 2011, the Peruvian Government approved the Plan Esperanza-a population-based national cancer control plan-in 2012. Legislation that ensured full government-supported funding for people who were otherwise unable to access or afford care and treatment accompanied the Plan. In 2013, the Ministry of Health requested an integrated mission of the Programme of Action for Cancer Therapy (imPACT) report to strengthen cancer control in Peru. The imPACT Review, which was executed in 2014, assessed Peru's achievements in cancer control, and areas for improvement, including cancer control planning, further development of population-based cancer registration, increased prevention, early diagnosis, treatment and palliative care, and the engagement and participation of civil society in the health-care system. This Series paper gives a brief history of the development of the Plan Esperanza, describes the innovative funding model that supports it, and summarises how funds are disseminated on the basis of disease, geography, and demographics. An overview of the imPACT Review, and the government's response in the context of the Plan Esperanza, is provided. The development and execution of the Plan Esperanza and the execution of and response to the imPACT Review demonstrates the Peruvian Government's commitment to fighting cancer across the country, including in remote and urban areas.

As part of a study dealing with the concentration of benzene, toluene, xylene, and ethylbenzene in the neigbourhood of fillings stations (indoor and outdoor air, benzene in the blood, t,t-muconous acid in urine), a total of about 70 volatile organic compounds were analysed in the `personal air` (personal sampler) of 13 persons living in the neighbourhood of the filling stations and 6 control persons during the summer of 1996. The mean concentrations of alkene and cycloalkene were below 3 {mu}g/m{sup 3}. The mean concentrations of benzene, m/p-xylene and toluene were 4.5 {mu}g/m{sup 3}, 6.8 {mu}g/m{sup 3}, and 34 {mu}g/m{sup 3}, respectively. The mean contamination of all other substances was below 3 {mu}g/m{sup 3}, halogenated hydrocarbons were below 1 {mu}g/m{sup 3}. The mean VOC-concentrations in the personal air of those persons living next to the filling stations and that seen in the control persons were not different. On the whole, the concentrations of total volatile organic substances were low, all the higher values could be explained by individual occupational or private activities (e.g. redecoration of the flat or smoking). Compared with the data of the `environmental survey` 1990/91, all substances revealed substantially lower mean values; we suggest that seasonal differences in the study time may be the main cause.

As a part of inter comparison exercise of an IAEA Coordinated Research Project on large sample neutron activation analysis, a large size and non standard geometry size pottery replica (obtained from Peru) was analyzed by k 0 -based internal monostandard neutron activation analysis (IM-NAA). Two large size sub samples (0.40 and 0.25 kg) were irradiated at graphite reflector position of AHWR Critical Facility in BARC, Trombay, Mumbai, India. Small samples (100-200 mg) were also analyzed by IM-NAA for comparison purpose. Radioactive assay was carried out using a 40 % relative efficiency HPGe detector. To examine homogeneity of the sample, counting was also carried out using X-Z rotary scanning unit. In situ relative detection efficiency was evaluated using gamma rays of the activation products in the irradiated sample in the energy range of 122-2,754 keV. Elemental concentration ratios with respect to Na of small size (100 mg mass) as well as large size (15 and 400 g) samples were used to check the homogeneity of the samples. Concentration ratios of 18 elements such as K, Sc, Cr, Mn, Fe, Co, Zn, As, Rb, Cs, La, Ce, Sm, Eu, Yb, Lu, Hf and Th with respect to Na (internal mono standard) were calculated using IM-NAA. Absolute concentrations were arrived at for both large and small samples using Na concentration, obtained from relative method of NAA. The percentage combined uncertainties at ±1 s confidence limit on the determined values were in the range of 3-9 %. Two IAEA reference materials SL-1 and SL-3 were analyzed by IM-NAA to evaluate accuracy of the method. (author)

Geothermal energy is of increasing importance as alternative, environmentally friendly technology for heat management. Direct interaction with the subsurface requires careful implementation, in particular in geological complex regions. The historical city Staufen im Breisgau, SW Germany, has attracted national attention as a case of implementation failure with severe consequences, causing debates on the applicability and security of this sustainable technique. Located at the eastern transition zone of the Upper Rhine Graben and the Schwarzwald massif, the geothermal potential is high at Staufen due to strong temperature gradients. In September 2007, seven boreholes for geothermal probes were drilled up to a depth of 140 m to provide a new heat management for the city hall. Within five years an uplift phenomenon has been observed in Staufen reaching more than 40 cm in places and 269 buildings were damaged. Hydro-chemical driven anhydrite-gypsum transformation in the subsurface was identified as the cause leading to volume increase that is observable as surface uplift. This process is associated with the geothermal drilling activities that have crossed several groundwater levels. In this work, we summarize and present the findings of spaceborne Synthetic Aperture Radar Interferometry (InSAR) analysis of the uplift in Staufen over the last five years from July 2008 through July 2013. By applying the Small Baseline Subset (SBAS) method, we find a localized elliptical-shaped deformation field in NE-SW orientation. Area of maximum uplift is located 50 m NNE of the drilling zone. At this location, we observe a cumulative uplift of approx. 13.7 cm ± 0.34 cm (mean value within an area of 30 m by 30 m) from July 2008 to July 2009, which reduced to cumulative uplift of 3 cm ± 0.25 cm from July 2012 to July 2013. The deceleration can be related to applied countermeasures as borehole sealing and groundwater pumping. The observed ground surface response was compared to

The condition of beech trees was investigated in six forest stands in the Bayerischer Wald and Boehmerwald mountains between 1995 and 1997 in order to establish the interdependence between tree conditions, the prevailing natural and anthropogenic site factors, and air pollution especially with groundlevel ozone. Details of the investigations are presented. Although a potential long-term effect of ozone cannot be excluded, the damage observed in beech trees in this region since the eighties is assumed to be caused not by a single factor but by complex interaction patterns between several anthropogenic and natural factors. [German] Es erfolgte im Untersuchungsgebiet Bayerischer Wald/Boehmerwald im Zeitraum 1995 bis 1997 eine detaillierte Zustandscharakterisierung von Altbuchen an sechs Standorten. Im Rahmen der Gesamtuntersuchung sollte geklaert werden, ob Zusammenhaenge zwischen dem Baumzustand und den herrschenden natuerlichen und anthropogenen Standortfaktoren und Luftbelastungen mit Schwerpunkt des bodennahen Ozons bestehen. An Hand kontinuierlicher Ozonmessungen konnte bestaetigt werden, dass die Konzentration des bodennahen Ozons im wesentlichen eine Funktion der Meereshoehe ist; somit ist an Hochlagenstandorten von hoeheren Immissionen auszugehen. Bei den moeglicherweise besser an photooxidativen Stress akklimatisierten Hochlagenbuchen waren die Schaeden bei erhoehter Ozonbelastung geringer ausgepraegt als bei Tieflagenbuchen. Fuer die Hypothese, wonach man eine staerkere Schaedigung der Hochlagenbestaende zu erwarten hat, wurde keine Bestaetigung gefunden. Inositol wird seit einiger Zeit als sensitiver Indikator diskutiert, der auf veraenderte Umweltbedingungen reagiert. Die Inositolkonzentration in Sonnenblaettern von Altbuchen im Bayerischen Wald war in 1995 um ca. 50% geringer als in 1996. Bei den Jungbuchen im Phytotronenexperiment kam es bei anhaltendem Ozonstress und zunehmender Schaedigung zu einer starken Reduktion der Inositolkonzentration in

Behind the poloidal limiter of the TRIAM-IM, the change with time lapse of the electron temperature and the plasma density at the time of OH discharge was examined by using a double probe. Scrape-off plasma parameters, namely the correlations of electron temperature, plasma density and ion flux with main plasma parameters were obtained. It was found that scrape-off density is almost proportional to square of beam average electron density. Further, it was determined by calculation that the density on the outermost shell magnetic surface is about 1.5 x 10 15 /m 2 . In the TRIAM-IM, it is expected that accompanying the increase of plasma current at the time of OH discharge, the effects of thermal load and particle load given to the limiter and the first wall increase, and the increase of the metallic impurities due to sputtering becomes a serious problem. The merits of double probe method are explained. The objective of this experiment is to examine the temperature and density of the plasma that comes in contact with the limiter and the wall by determining the basic parameters of peripheral plasma at the time of OH discharge. In order to heighten the reliability of data, the examination was carried out from both aspects of hardware and software. The TRIAM-IM, double probe measuring system and its theory, applied voltage sweeping part, signal processing system, data processing system, and the experimental results of scrape-off layer parameters are described.

Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or longer mission life for stationary landers/laboratories. We describe here the development of a miniature GC - Minicell Ion Mobility Spectrometer (IMS) under development through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA's Small Business Innovative Research (SBIR) Program.

Full Text Available This study tried to clarify the antagonistic effect of the lipopeptides secreted by Bacillus amyloliquefaciens strain BPD1 (Ba-BPD1 against Pyricularia oryzae Cavara (PO. To determine the major antifungal lipopeptides effective against PO, single and dual cultures were carried out in solid-state media. The matrix-assisted laser desorption/ionization–time of flight imaging mass spectrometry (MALDI-TOF IMS was used to identify the most effective lipopeptide in situ. Meanwhile, the morphology of pathogen fungi treated with lipopeptides was observed via the SEM. Of the three lipopeptide families, surfactin, iturin, and fengycin, the last was identified as the most effective for inhibiting mycelium growth and conidial germination of PO. The conidia and hyphae of fengycin-treated PO were shown to become deformed and tumorous under exposure. This study provides insights into the antagonistic effect of Ba-BPD1 against fungal phytopathogens. Such insights are helpful in the development of reagents for biological control applications.

Terroristen fühlen sich in sozialen Medien wohler als man denken könnte. Im Netz können sie die asymmetrische Kräfteverteilung überwinden, die sie in der offenen Feldschlacht unterlegen sein ließe. Terroristen machen sich das Bild zur Waffe und produzieren erst durch die Positionierung an der Medienfront Sinn in ihren Taten. Ohne ein Bekennerschreiben, ein Abschiedsvideo des Attentäters oder ein letztes Posting im sozialen Netzwerk wäre ein Bombenanschlag nichts als ein Kapitalverbrechen. Durch die terroristische Kommunikationsstrategie wird das Verbrechen erst zum terroristischen Akt. Das ist die theoretische Grundannahme dieses Aufsatzes. Ohne Medienberichterstattung könnten terroristische Organisationen nicht existieren.

The Provisional Technical Secretariat (PTS) of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has a continuous interest in enhancing its capability in infrasound source localization and characterization. This capability is based on the processing of data recorded by the infrasound network of the International Monitoring System (IMS). This infrasound network consists of sixty stations, among which forty-five are already certified and continuously transmit data to the International Data Center (IDC) in Vienna, Austria. Each infrasound station is composed of an array of infrasound sensors capable of measuring micro-pressure changes produced at ground level by infrasonic waves. It is the responsibility of the Engineering and Development Section of the IMS Division to ensure the highest quality for IMS infrasound data. This includes the design of robust and reliable infrasound stations, the use of accurate and calibrated infrasound measuring chains, the installation of efficient wind noise reduction systems and the implementation of quality-control tools. The purpose of this paper is to present ongoing PTS infrasound engineering and development projects related to the testing and validation of wind noise reduction system models, the implementation of infrasound data QC tools, the definition of guidelines for the design of IMS power supply systems and the development of a portable infrasound calibrator and of field kits for site survey and certification.

Common sense, the thinking of the people par excellence, asserts that: a picture is worth a thousand words. This is a big mistake. The images are not carriers of meanings. The images always go through three basic processes are: production, circulation and reception. These processes are always determined in the time and social space. They are always the result of multiple relationships (social, ideological, political, moral, religious, etc., established with them. Always there are so many elements beyond the image, which determines its meaning. The meaning of an image always depends on the relationships established with it in a historical time and space, socially and culturally determined. The images are never alone. To decrypt their meanings, you must first know the symbolic life of the societies in which they appear. Images do not have a single meaning because it depends on the historical and cultural geography which presents. The images always have a close relationship with the society they were born.

Organic micropollutants in seapage and groundwater after agricultural use of sewage sludge; Organische Spurenstoffe im Sicker- und Grundwasser bei landwirtschaftlicher Nutzung von Klaerschlamm

Influences on groundwater quality due to agricultural use of sewage sludge have been estimated with special focus to organic micropollutants. Pilot plants filled with sand and arable soil were used for the simulation of sludge application, ploughing and parching of soil surface. The investigated parameters included PAH, phenols, phthalates, heavy metals, anions, cations, and other. All of the three simulation types resulted in a parameter specific variation of the groundwater quality. Transportation of most of the organic substances took place immediately after fertilization in a water soluted or particular bound manner. PAH in contrary adsorbed on the filter material. Furthermore microbial degradation products could be observed. Copper, ammonia and nitrate reproduceable exceeded the given drinking water standards. No significant increase in heavy metal or organic load could be detected in the soil or sand. Analytical pilot investigations indicated the occurrence of organic pollutants solved in the sludge water fraction, bound on small particles and adsorbed on the solid sludge phase. Particulary bounded concentrations sometimes increased the adsorbed ones. In total, approximately 55 single organic compounds could be identified within sewage sludge of different origin. Their further environmental behaviour depends on the distribution between the three sludge fractions. (orig.)

Sequence analysis by iterated maps, a review.

Science.gov (United States)

Almeida, Jonas S

2014-05-01

Among alignment-free methods, Iterated Maps (IMs) are on a particular extreme: they are also scale free (order free). The use of IMs for sequence analysis is also distinct from other alignment-free methodologies in being rooted in statistical mechanics instead of computational linguistics. Both of these roots go back over two decades to the use of fractal geometry in the characterization of phase-space representations. The time series analysis origin of the field is betrayed by the title of the manuscript that started this alignment-free subdomain in 1990, 'Chaos Game Representation'. The clash between the analysis of sequences as continuous series and the better established use of Markovian approaches to discrete series was almost immediate, with a defining critique published in same journal 2 years later. The rest of that decade would go by before the scale-free nature of the IM space was uncovered. The ensuing decade saw this scalability generalized for non-genomic alphabets as well as an interest in its use for graphic representation of biological sequences. Finally, in the past couple of years, in step with the emergence of BigData and MapReduce as a new computational paradigm, there is a surprising third act in the IM story. Multiple reports have described gains in computational efficiency of multiple orders of magnitude over more conventional sequence analysis methodologies. The stage appears to be now set for a recasting of IMs with a central role in processing nextgen sequencing results.

Die Aufklärung schwer kranker Patienten im interprofessionellen Kontext [Breaking bad news

Schildmann, Jan

2006-11-01

Full Text Available [english] Background: Breaking bad news is a frequent and difficult communication situation in clinical practice. Informing patients about bad news is part of physicians’ tasks. Nurses may support patients during the process of realising bad news on a cognitive as well as emotional level. Empirical studies show that experiential courses are effective measures to train communication skills. This paper presents the course concept of an interprofessional teaching session for medical and nursing students on the communication with seriously ill patients. Description of the project: Since 2002, 54 participants took part in seven courses. Teaching aims are the development of competences to provide feedback as well as communication skills with respect to discussions with seriously ill patients. In addition students get to know the specific tasks both professions encounter in the context of discussions with patients who had been diagnosed with a serious illness. Role plays with simulated patients, small group discussions as well as a session with clinically experienced physicians and nurses are the main teaching methods. Conclusion: The optional course has been well accepted by both student groups. In addition to the analysis of individual communication skills participants use the collaborative teaching sessions to discuss the options of an interprofessional approach of breaking bad news. There is a lack of scientific literature regarding the criteria of interprofessional concepts of breaking bad news. Such research is necessary to define specific teaching aims of collaborative courses on disclosing bad news and will serve as a fundament for future evaluation studies.

Conventional projection radiography (chest x-ray) is one of the most frequently requested procedures in radiology. Even though chest x-ray imaging is frequently performed in asymptomatic patients for preoperative assessment, clinically relevant incidental findings are relatively scarce. This is due to the relatively low sensitivity of chest x-rays where few clinically relevant incidental findings are to be expected, as any detectable pathologies will as a rule already be clinically symptomatic. Recommendations from relevant societies for the management of incidental findings, apart from the clarification of incidental nodules, do not exist. This review article therefore describes the most frequent and typical incidental findings of lung parenchyma (apart from pulmonary nodules), mediastinal structures including the hilum of the lungs, pleura, chest wall and major vessels. Also described are those findings which can be diagnosed with sufficient certainty from chest x-rays so that further clarification is not necessary and those which must be further clarified by multislice imaging procedures or other techniques. (orig.) [German] Eine der haeufigsten Untersuchungen in der Radiologie ist die konventionelle Projektionsradiographie des Thorax (Roentgenthorax). Auch wenn projektionsradiographische Aufnahmen im Rahmen einer praeoperativen Abklaerung haeufig als orientierende Untersuchung angefertigt werden, sind - bedingt durch die relativ geringe Sensitivitaet des Roentgenthorax - wenig klinisch relevante Zufallsbefunde zu erwarten, da nachweisbare Pathologien in der Regel bereits auch klinisch apparent sind. Empfehlungen entsprechender Fachgesellschaften zu Zufallsbefunden im Roentgenthorax jenseits der Abklaerung von Rundherden liegen nicht vor. Die vorliegende Arbeit beleuchtet daher haeufige und typische Zufallsbefunde des Lungenparenchyms (ausser den Lungenrundherden), der mediastinalen Strukturen einschliesslich der Hili, der Pleura, der Thoraxwand sowie der

Superplastic deformation of P/M and I/M Al-Li based alloys

International Nuclear Information System (INIS)

Lederich, R.J.; Sastry, S.M.L.

1984-01-01

Incremental strain-rate and constant strain-rate cone-forming tests have been carried out at 450-550 C to investigate the superplastic forming characteristics of Al-Li-Cu-Mn, Al-Li-Cu-Mg-Zr, and Al-Li-Zn-Mg alloys processed by powder-metallurgy (P/M) and ingot-metallurgy (I/M) techniques. It is found that P/M Al-Li alloys containing 0.2 pct Zr are inherently superplastically formable without the need for extensive thermomechanical processing. I/M Al-Li alloys containing Zr are also superplastically formable. The mechanical properties of the superplastically formed and solution-treated-and-aged alloys are comparable to those of solution-treated-and-aged alloys before superplastic forming. 6 references

Kojiro, Daniel R.; Mancinelli, Rocco; Martin, Joe; Holland, Paul M.; Stimac, Robert M.; Kaye, William J.

2005-01-01

The Mars Geochemical Instrument, MarGI, was developed to provide a comprehensive analysis of the rocks and surface material on Mars. The instrument combines Differential Thermal Analysis (DTA) with miniature Gas Chromatography-Ion Mobility Spectrometry (GC-IMS) to identify minerals, the presence and state of water, and organic compounds. Miniature pyrolysis ovens are used to both, conduct DTA analysis of soil or crushed rocks samples, and pyrolyze the samples at temperatures up to 1000 degrees C for GC-IMS analysis of the released gases. This combination of analytical processes and techniques, which can characterize the mineralogy of the rocks and soil, and identify and quantify volatiles released during pyrolysis, has applications across a wide range of target sites including comets, planets, asteroids, and moons such as Titan and Europa. The MarGI analytical approach evolved from the Cometary Ice and Dust Experiment (CIDEX) selected to fly on the Comet Rendezvous Asteroid Flyby Mission (CRAF).

Water shortages and the drive to recycle is increasing interest in reuse of reclaimed wastewater. Timely and cost-effective ways to detect fecal pollutants prior to reuse increases confidence of residents and neighbors concerned about reuse of reclaimed wastewater. The on-site wastewater treatment and reuse systems (OWTRS) used in this study include a septic tank, peat bioreactor, ClO(2) disinfection and land spray irrigation system. Bacteroides fragilis, Escherichia coli and Enterococcus spp., were tested with immunomagnetic separation/ATP bioluminescence (IMS/ATP), qPCR and culture-based methods. The results displayed a 2-log reduction in fecal bacteria in the peat bioreactor and a 5-log reduction following chloride dioxide disinfection. The fecal bacteria levels measured by IMS/ATP correlated with qPCR results: HuBac 16S (R(2) = 0.903), Bf-group 16S (R(2) = 0.956), gyrB (R(2) = 0.673), and Ent 23S (R(2) = 0.724). This is the first study in which the newly developed human-specific IMS/ATP and previously developed IMS/ATP were applied for determining OWTRS efficiency. Results of the study revealed that IMS/ATP is a timely and cost-effective way to detect fecal contaminants, and results were validated with qPCR and culture based methods. The new IMS/ATP can also be applied broadly in the detection of human-originated fecal contamination. Copyright © 2012 Elsevier Ltd. All rights reserved.

To automate astronaut organ and effective dose calculations from occupational X-ray and computed tomography (CT) examinations incorporating PCXMC and ImPACT tools and to estimate the associated lifetime cancer risk per the National Council on Radiation Protection & Measurements (NCRP) using MATLAB(R). Methods: NASA follows guidance from the NCRP on its operational radiation safety program for astronauts. NCRP Report 142 recommends that astronauts be informed of the cancer risks from reported exposures to ionizing radiation from medical imaging. MATLAB(R) code was written to retrieve exam parameters for medical imaging procedures from a NASA database, calculate associated dose and risk, and return results to the database, using the Microsoft .NET Framework. This code interfaces with the PCXMC executable and emulates the ImPACT Excel spreadsheet to calculate organ doses from X-rays and CTs, respectively, eliminating the need to utilize the PCXMC graphical user interface (except for a few special cases) and the ImPACT spreadsheet. Results: Using MATLAB(R) code to interface with PCXMC and replicate ImPACT dose calculation allowed for rapid evaluation of multiple medical imaging exams. The user inputs the exam parameter data into the database and runs the code. Based on the imaging modality and input parameters, the organ doses are calculated. Output files are created for record, and organ doses, effective dose, and cancer risks associated with each exam are written to the database. Annual and post-flight exposure reports, which are used by the flight surgeon to brief the astronaut, are generated from the database. Conclusions: Automating PCXMC and ImPACT for evaluation of NASA astronaut medical imaging radiation procedures allowed for a traceable and rapid method for tracking projected cancer risks associated with over 12,000 exposures. This code will be used to evaluate future medical radiation exposures, and can easily be modified to accommodate changes to the risk

Epstein-Barr virus (EBV) is the most common cause of infectious mononucleosis (IM) and establishes lifetime infection associated with a variety of cancers and autoimmune diseases. The aim of this study was to develop an integrative gene regulatory network (GRN) approach and overlying gene expression data to identify the representative subnetworks for IM and EBV latent infection (LI). After identifying differentially expressed genes (DEGs) in both IM and LI gene expression profiles, functional annotations were applied using gene ontology (GO) and BiNGO tools, and construction of GRNs, topological analysis and identification of modules were carried out using several plugins of Cytoscape. In parallel, a human-EBV GRN was generated using the Hu-Vir database for further analyses. Our analysis revealed that the majority of DEGs in both IM and LI were involved in cell-cycle and DNA repair processes. However, these genes showed a significant negative correlation in the IM and LI states. Furthermore, cyclin-dependent kinase 2 (CDK2) - a hub gene with the highest centrality score - appeared to be the key player in cell cycle regulation in IM disease. The most significant functional modules in the IM and LI states were involved in the regulation of the cell cycle and apoptosis, respectively. Human-EBV network analysis revealed several direct targets of EBV proteins during IM disease. Our study provides an important first report on the response to IM/LI EBV infection in humans. An important aspect of our data was the upregulation of genes associated with cell cycle progression and proliferation.

Propofol is a commonly used intravenous general anesthetic. Multi-capillary column (MCC) coupled Ion-mobility spectrometry (IMS) can be used to quantify exhaled propofol, and thus estimate plasma drug concentration. Here, we present results of the calibration and analytical validation of a MCC/IMS pre-market prototype for propofol quantification in exhaled air. Calibration with a reference gas generator yielded an R 2 ≥0.99 with a linear array for the calibration curve from 0 to 20 ppb v . The limit of quantification was 0.3 ppb v and the limit of detection was 0.1 ppb v . The device is able to distinguish concentration differences >0.5 ppb v for the concentration range between 2 and 4 ppb v and >0.9 ppb v for the range between 28 and 30 ppb v . The imprecision at 20 ppb v is 11.3% whereas it is 3.5% at a concentration of 40 ppb v . The carry-over duration is 3min. The MCC/IMS we tested provided online quantification of gaseous propofol over the clinically relevant range at measurement frequencies of one measurement each minute. Copyright © 2017 Elsevier B.V.

The technical developments of recent years, such as the introduction of helium as a stripping gas, make compact AMS systems probably among the most sensitive analyzers available for ultra-trace analyzes of actinides in the environment. Such systems are particularly suitable for the trace analysis of {sup 236}U since conventional mass spectrometry does not provide the necessary suppression of the substrate caused by molecules or neighboring masses. Over the past few years, unique data sets of {sup 236}U/{sup 238}U have been produced at the AMS System Tandy of the ETH Zurich in the Atlantic and Arctic Ocean as well as in the Mediterranean and the North Sea. This lecture will provide a brief overview of the latest technical developments in the field of heavy ion analysis at compact AMS plants at ETH Zurich. In the second part, the produced data sets are then assembled and the current understanding of this new ocean tracer discussed.

Single-molecule studies of the Im7 folding landscape.

Pugh, Sara D; Gell, Christopher; Smith, D Alastair; Radford, Sheena E; Brockwell, David J

2010-04-23

Under appropriate conditions, the four-helical Im7 (immunity protein 7) folds from an ensemble of unfolded conformers to a highly compact native state via an on-pathway intermediate. Here, we investigate the unfolded, intermediate, and native states populated during folding using diffusion single-pair fluorescence resonance energy transfer by measuring the efficiency of energy transfer (or proximity or P ratio) between pairs of fluorophores introduced into the side chains of cysteine residues placed in the center of helices 1 and 4, 1 and 3, or 2 and 4. We show that while the native states of each variant give rise to a single narrow distribution with high P values, the distributions of the intermediates trapped at equilibrium (denoted I(eqm)) are fitted by two Gaussian distributions. Modulation of the folding conditions from those that stabilize the intermediate to those that destabilize the intermediate enabled the distribution of lower P value to be assigned to the population of the unfolded ensemble in equilibrium with the intermediate state. The reduced stability of the I(eqm) variants allowed analysis of the effect of denaturant concentration on the compaction and breadth of the unfolded state ensemble to be quantified from 0 to 6 M urea. Significant compaction is observed as the concentration of urea is decreased in both the presence and absence of sodium sulfate, as previously reported for a variety of proteins. In the presence of Na(2)SO(4) in 0 M urea, the P value of the unfolded state ensemble approaches that of the native state. Concurrent with compaction, the ensemble displays increased peak width of P values, possibly reflecting a reduction in the rate of conformational exchange among iso-energetic unfolded, but compact conformations. The results provide new insights into the initial stages of folding of Im7 and suggest that the unfolded state is highly conformationally constrained at the outset of folding. (c) 2010 Elsevier Ltd.

The purpose of this study is to determine the effect of assertive impression management (IM) tactics, such as personal storytelling and self-promotion, on job interview outcomes of people with epilepsy. Specifically, the effect of IM on interviewers' subjective impressions and evaluation of hireability of job candidates with epilepsy were examined. Ninety-nine master's level graduate students majoring in business or human resources were randomly assigned to three experimental conditions to view one of three 15-min video clips of a job applicant interviewing for a technical computer sales position. The three experimental conditions were (1) job applicant who did not disclose any disability, (2) job applicant with epilepsy who did not use IM tactics, and (3) job applicant with epilepsy who used IM tactics. After watching the job interview video portraying the experimental conditions, participants were asked to rate the job applicant in terms of general impression and hireability for the described position. The use of IM was found to have a significant effect on job interview outcomes (p business/human resources students on both general impression and hireability for the job applicant with epilepsy and IM condition were significantly higher than for the job applicant with epilepsy who did not use IM condition. Furthermore, mediation analysis revealed that general impression is a mediator for the relationship between IM and interview outcomes. This study demonstrates that IM has a significant and positive effect on job interview outcomes for persons with epilepsy. IM can be used as a powerful strategy for empowering people with epilepsy to combat disability stigma, and offset negative perceptions of employers about the potential of this population to be productive workers.

ImWalkMF: Joint matrix factorization and implicit walk integrative learning for recommendation

KAUST Repository

Zhang, Chuxu

2018-01-15

Data sparsity and cold-start problems are prevalent in recommender systems. To address such problems, both the observable explicit social information (e.g., user-user trust connections) and the inferable implicit correlations (e.g., implicit neighbors computed by similarity measurement) have been introduced to complement user-item ratings data for improving the performances of traditional model-based recommendation algorithms such as matrix factorization. Although effective, (1) the utilization of the explicit user-user social relationships suffers from the weakness of unavailability in real systems such as Netflix or the issue of sparse observable content like 0.03% trust density in Epinions, thus there is no or little explicit social information that can be employed to improve baseline model in real applications; (2) the current similarity measurement approaches focus on inferring implicit correlations between a user (item) and their direct neighbors or top-k similar neighbors based on user-item ratings bipartite network, so that they fail to comprehensively unfold the indirect potential relationships among users and items. To solve these issues regarding both explicit/implicit social recommendation algorithms, we design a joint model of matrix factorization and implicit walk integrative learning, i.e., ImWalkMF, which only uses explicit ratings information yet models both direct rating feedbacks and multiple direct/indirect implicit correlations among users and items from a random walk perspective. We further propose a combined strategy for training two independent components in the proposed model based on sampling. The experimental results on two real-world sparse datasets demonstrate that ImWalkMF outperforms the traditional regularized/probabilistic matrix factorization models as well as other competitive baselines that utilize explicit/implicit social information.

In order to assess the terrestrial hazard potential of polycyclic aromatic hydrocarbons (PAHs), it is vital to investigate their nuisance concentrations and deposition to soil and plants as well as their dislocation in soil. This was the object of the first part of the research programme ``Locational evaluation of chemical soil pollution``, conducted by the national research institutions. It was headed ``Analysis of exposure`` and comprised the following individual contributions: 1. Integrated long-term measurements of polycyclic aromatic hydrocarbons in soil air at ground level (FZJ), 2. Determination of PAH nuisance concentrations at the Scheyern experimental station as well as at the motorway by-passing Munich to the east (A 99), near Kirchheim (GSF), 3. Investigations regarding PAH exposure via the air pathway and inclusion of acquired data in substance flows made up for the east-German dry zone (Bad Lauchstaedt), (UFZ), 4.

Specifically, 9,733 Hispanic, Spanish-speaking athletes who completed the ImPACT test in English and 2,087 Hispanic, Spanish-speaking athletes who completed the test in Spanish were compared with 11,955 English-speaking athletes who completed the test in English. Athletes were assigned to age groups (13-15, 16-18). Results revealed a significant effect of language group (p Spanish-speaking athletes completing the test in Spanish scored more poorly than Spanish-speaking and English-speaking athletes completing the test in English, on all Composite scores and Total Symptom scores. Spanish-speaking athletes completing the test in English also performed more poorly than English-speaking athletes completing the test in English on three Composite scores. These differences in performance and reported symptoms highlight the need for caution in interpreting ImPACT test data for Hispanic Americans.

The largest natural gas pool in the world is located in northern part of the West Siberian Basin. During the Quaternary this reservoir became overlaid with several hundreds of metres of permafrost. The pressure and temperature conditions prevailing under this permafrost zone have led to the development of gas hydrates. As far as is known today there is no genetic relationship between the formation of the gas pool and the development of gas hydrates. The present contribution deals with these questions in detail. (MSK) [Deutsch] Im Nordteil des westsibirischen Beckens liegt die groesste Erdgaslagerstaette der Erde. Darueber hat sich im Quartaer ein mehrere hundert Meter maechtiger Permafrost gebildet.

Three novel metal-organic frameworks (MOFs), |(C3H 7NO)2(H2O)|[Zn3(C10H 5N3O4)3(C3H 7NO)2] (1), |(H2O)5(H 3O)(NO3)|[Nd2(C10H5N 3O4)3(H2O)4] (2), and |(H2O)2|[Nd3(C10H5N 3O4)3(C10H4N 3O4)] (3), based on the T-shaped tripodal ligands 2-(pyridine-4-yl)-1H-4,5-imidazoledicarboxylic acid and 2-(pyridine-3-yl)-1H-4, 5-imidazoledicarboxylic acid (H3PyImDC), have been constructed under solvo-/hydrothermal conditions. The diverse coordination modes of H 3PyImDC ligands have afforded the assembly of three novel compounds. In compound 1, two oxygen atoms and three nitrogen atoms of the H 3PyImDC ligand, a T-shaped linker, coordinate to two zinc centers to form a novel bbm net with two distinct channels along the [100] and [001] directions. In compound 2, H3PyImDC ligands coordinate to neodymium centers to form a ladder-like chain which then interacts with a water molecules chain via hydrogen-bondings to construct a 3D supermolecular structure. In compound 3, H3PyImDC ligands, a T-shaped linker, coordinate to neodymium centers to form a (3,6)-connected net with an ant topology. In compounds 1-3, the two H3PyImDC ligands exhibit different coordination modes with zinc and neodymium centers, which afforded the expected structural diversity. Additionally, all three compounds exhibit strong fluorescence emissions in the solid state at room temperature. © 2010 American Chemical Society.

Full Text Available The International Magnetospheric Study (IMS was carried out for three years from 1976. The Japanese Antarctic Research Expedition (JARE participated in this IMS project. The main purpose of the IMS project in JARE was the synthetic observation of polar magnetic substorms. In order to study polar magnetic substorms, a multipoint ground observation network was planned around Syowa, including unmanned stations. In the construction of an unmanned observatory system in Antarctica, there have been difficulties, such as insuffcient information about enviromental conditions, the construction support capability, power supply and others. During the IMS period, the U. S. A., former Soviet Union, Australia and the United Kingdom also started to develop unmanned observation systems. In this report, we describe the development of a JARE unmanned observatory for upper atmosphere physics and also the scientific results.

Studies on agglomeration of colloidal suspensions in an alternating electric field; Untersuchungen zur Agglomeration kolloidaler Suspensionen im elektrischen Wechselfeld

Colloidal solutions contain particles in the {mu}m range whose agglomeration and coagulation is of interest for certain applications. `Electrocoagulation` means that in an electric field droplets or particles in a disperse phase have higher kinetic energy so that the probability of overcoming repulsive forces and of forming bigger aggregates will increase. The electrocoagulation technique is applied for emulsion cracking of water-in-oil systems (desalination and dewatering of petroleum, petroleum cracking) and, in some cases, also for cracking oil-in-water systems. Removal of colloidal solids from aqueous solution during electrochemical waste water treatment is often carried out with the aid of dissolving aluminium or iron electrodes. The authors describe experiments in which the flow of an electric current, which would cause the electrodes to dissolve, was to be prevented. An alternating field was to induce oscillation of the particles, i.e. relative motion of the particles with respect to each other. (orig./SR) [Deutsch] Kolloidale Loesungen enthalten Partikel im {mu}m-Bereich. In manchen Bereichen ist deren Agglomeration bzw. Koagulation von Interesse. Unter dem Begriff der Elektrokoagulation versteht man im allgemeinen das Phaenomen, dass in einem elektrischen Feld Tropfen oder Partikel in einer dispersen Phase eine hoehere kinetische Energie besitzen, und dadurch die Wahrscheinlichkeit zur Ueberwindung von Abstossungskraeften und zur Bildung groesserer Aggregate steigt. Das Verfahren der Elektrokoagulation wird bisher zur Emulsionsspaltung von Wasser/Oel-Systemen (Entsaltzung und Entwaesserung von Erdoel/Erdoelspaltung) und z.T. auch zur Spaltung von Oel/Wasser-Systemen eingesetzt. Zur Entfernung kolloidaler Feststoffe aus waessrigen Loesungen bei der elektrochemischen Aufarbeitung von Abwasser wird haeufig mit sich aufloesenden Aluminium- oder Eisenelektroden gearbeitet.

Die Autorinnen untersuchen in ihren Beiträgen, die in vier Schwerpunkte – Staat, Markt, Recht/Eigentum und Liebe/Sexualität – gegliedert sind, wie ‚Freiheit‘ im Kontext neoliberaler Transformationen auf eine im Vergleich mit der fordistisch organisierten Gesellschaft neue Weise diskursiviert, institutionalisiert und reguliert wird und wie sich dabei das Verhältnis von Freiheit und Geschlecht neu figuriert. Neben den Veränderungen in Geschlechterverhältnissen und praktizierten Geschlechterarrangements stehen die Möglichkeiten feministischer geschlechterpolitischer Interventionen im Mittelpunkt des Interesses.In modern societies freedom and equality belong to those core values that are positive as well as vague. The authors examine how, in the context of neoliberal transformations, ‘freedom’ becomes discursive, institutionalized, and regulated in new ways in comparison to those societies organized according to Fordism and how this reconfigures the relationship between freedom and equality. The contributions are divided into four themes: state, market, law/ownership, and love/sexuality. Of central interest to the study are the transformations in gender relations and gender arrangements in practice as well as the possibilities for feminist gender-political interventions.

The thermal efficiency of subject systems, especially at higher temperatures is influenced by heat and humidity transport underground. Thermal conductivity and specific thermal capacity depend on the humidity content of the soil. A simulation model was developed that describes the coupled heat and humidity transport in the temperature range up to 90 C. This model will be validated in laboratory and field tests and then be used for designing and analysing underground stores. Pilot plants for the storage of industrial waste heat were designed and planned on the basis of this simulation. In both cases these are cogeneration plants whose waste heat was to be used for space heating and as process energy. Both plants have a very high demand of electric energy which is mostly supplied by the cogeneration plant. The waste heat is put into the store during the summer. In the winter heat is supplied by both the store and the cogeneration plant. In both cases the store has a volume of approx. 15,000 cubic metres with 140 and 210 pits located in a depth of 30 and 40 metres. The plants are used to carry out extensive measurements for the validation of simulation models. (orig.) [Deutsch] Die thermische Leistungsfaehigkeit solcher Systeme wird insbesondere im hoeheren Temperaturbereich durch den Waerme- und Feuchtetransport im Untergrund beeinflusst.

Es wurde ein Simulationsmodell entwickelt, das den gekoppelten Waerme- und Feuchtetransport im Temperaturbereich bis 90 C beschreibt. Dieses Modell wird an Labor- und Feldexperimenten validiert und dient dann zur Auslegung und Analyse von Erdwaermesonden-Speichern. Basierend auf diesen theoretischen Grundlagenarbeiten wurden Pilotanlagen zur saisonalen Speicherung industrieller Abwaerme ausgelegt und geplant.

Full Text Available Zur Förderung von Medienkompetenz und medienpädagogischer Kompetenz in der universitären Lehramtsausbildung wurde an der Justus-Liebig-Universität Gießen ein Lehrprojekt initiiert, das an der aktuellen technologischen Ausstattung von deutschen Schulen ansetzt. Als Zugang wurde die Technologie der interaktiven Whitebords gewählt, um gegenwärtige Entwicklungen der Digitalisierung von Unterrichtsräumen zu thematisieren und dabei ausgewählte Aspekte von Medienkompetenz zu fördern. In dem Projekt haben verschiedene Einrichtungen der Universität und der Lehrerbildung kooperiert, um eine Multiplikator/-innenschulung für Studierende zu erarbeiten und zu etablieren. Es wurde eine 28-stündige Qualifizierungsreihe entwickelt, die sich aus modularisierten Workshops zur medientechnischen und -didaktischen Auseinandersetzung mit interaktiven Whiteboards, Elementen der Tutor/-innenausbildung sowie der Erarbeitung eines eigenen Unterrichtsentwurfes zusammensetzt. In dem Artikel werden die entwickelten Module vorgestellt und bewertet, inwieweit sie den von Herzig, Aßmann und Klar (2014 formulierten Zielvorstellungen zur Medienkompetenzförderung für das Lehramtsstudium entsprechen. Im Abgleich mit diesen Zielvorstellungen werden Entwicklungspotentiale des Konzepts identifiziert. Darüber hinaus fliessen Ergebnisse der praktischen Durchführung in Optimierungsvorschläge zur Steigerung der Nachhaltigkeit und Qualität der didaktischen Kompetenzen zum Einsatz von interaktiven Whiteboards in der Lehramtsausbildung – und darüber vermittelt im Schulunterricht – ein.

Einige Überlegungen zur Bestimmung des Äquivalenzgrades am Beispiel des lexikalischen Feldes „Erhebung im Gelände“

Full Text Available Eine der wichtigsten Fragen in der kontrastiven Lexikologie, zweisprachigen Lexikografie und der Übersetzungswissenschaft ist die Bestimmung des Äquivalenzgrades zwischen den Lexemen der Vergleichssprachen. Die meisten Lexikologen, die sich mit kontrastiven Untersuchungen beschäftigen, sprechen von der Voll-, Teil- und Nulläquivalenz. In der Praxis existiert allerdings nur die so genannte Teiläquivalenz. Wenn man aber in der wissenschaftlichen Diskussion nur diesen Begriff verwenden würde, entstünden somit noch größere Schwierigkeiten bei der Bestimmung des Äquivalenzgrades, weil sich das Spektrum der Teiläquivalenz von 1 bis 99 Prozent erstrecken würde. Daher wird im vorliegenden Beitrag eine Formel zur Berechnung des Äquivalenzgrades zwischen zwei Vergleichslexemen vorgeschlagen. In erster Linie wird die semantische Analyse des lexikalischen Feldes „Erhebung im Gelände“ im Litauischen und im Deutschen, das die Grundlage der Formel bildet, kurz präsentiert. Dazu wird der von Helmut Henne und Herbert Ernst Wiegand (Henne 1972, Wiegand 1970, Kühn 1979 vorgeschlagene Entwurf, die lexikalische Bedeutung mit Hilfe von onomasiologischen, komplementär-semasiologischen und autonom-semasiologischen Operationsschritten zu beschreiben, herangezogen. Dieser Entwurf wird durch kontrastive, prototypensemantische und korpusgestützte Aspekte ergänzt. Im zweiten Teil wird die mathematische Formel zur Berechnung des Äquivalenzgrades zwischen zwei Vergleichslexemen angegeben und durch das Beispiel des Lexempaars kalva–Hügel veranschaulicht.

Full Text Available Background: Imaging mass spectrometry (IMS generates molecular images directly from tissue sections to provide better diagnostic insights and expand the capabilities of clinical anatomic pathology. Although IMS technology has matured over recent years, the link between microscopy imaging currently used by pathologists and MS-based molecular imaging has not been established. Methods: We adapted the Vanderbilt University Tissue Core workflow for IMS into a web-based system that facilitates remote collaboration. The platform was designed to perform within acceptable web response times for viewing, annotating, and processing high resolution microscopy images. Results: We describe a microscopy-driven approach to tissue analysis by IMS. Conclusion: The Pathology Interface for Mass Spectrometry is designed to provide clinical access to IMS technology and deliver enhanced diagnostic value.

1990-01-01

Ion Mobility Spectrometry (IMS) is one analytical technique being investigated for the in situ analysis of the atmosphere of Titan. Any hydrocarbon ions that may form react immediately, in microseconds, with the high concentration of water vapor normally present in conventional IMS. By reducing the water concentration to the parts-per-billion range, the lifetime of the hydrocarbon ions may be increased to the milliseconds required for measurement. At low water level concentrations, other species may become the reactant ion. This study focuses on IMS analysis of expected Titan atmospheric hydrocarbons under very dry, low water concentration conditions

This volume contains contributions resulting from an expert discussion on 'Technology Images and Concepts of Technology in Transition - an analysis in the philosophy of technology and general technology. This expert discussion took place on 6 October 2000 at the State Pedagogical Institute Brandenburg in Ludwigsfelde-Struveshof and was conceived and organized co-operatively by the Forschungszentrum Karlsruhe, Institute for Technology Assessment and Systems Analysis, the University of Potsdam, Institute for the Theory of Work/Technology and Professor Horst Wolffgramm, Frankfurt (Oder). It was the aim of the expert discussion to compile, compare and relate the various positions in the philosophy of technology, general technology science, the history of technology and the didactics of technology of the 'conceptualisation' of technology as a basis for generally understanding technology or for a scientifically based 'image of technology' to each other, and then to make them accessible for curricula within a framework of conceiving general technical education at all school levels. The contributions are grouped according to the two main foci of the event: On the one hand they are concerned with determining a contemporary concept of technology ('Image of technology'). One of the aims is to characterize technological change from the historical-genetic perspective and in this way to access technology as a work of mankind, as an important element of our culture. At the same time it is necessary to forecast future developments or to make future paths of development visible to enable the indication of change by basic innovations. Second, on this basis and supported by educational theory, conclusions are drawn for future-oriented technical general education for all students. The main focus in this is on the linkage between goals, content and subject-specific methods. In order to enable the determination of competence of any individual

The aim of the project was to identify areas in households and the tertiary sector in which changes in behaviour could result in energy conservation and thus a reduction of greenhouse gas emissions, and to quantify the potentials for 1995, 2005 and 2020. A second focus was on the analysis and evaluation of programmes and instruments to realise the potentials. With literature evaluation, expert interviews, and a household servey potentials and further technical development have been identified. In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

Controlled impulsive scientific underwater sound sources in the Northwestern Pacific were observed at two IMS hydroacoustic stations in the Pacific Ocean. Although these experiments were conducted with the aim of studying the physical properties of the plate boundaries inside the Earth, they are also suitable for the investigation of long range underwater acoustic detections. In spite of the fact that the energy of these controlled impulsive scientific sources is significantly smaller than that of nuclear explosions, the signals were obtained by IMS hydrophone stations thousands of kilometres away and also by distant ocean bottom instruments operated by various Institutes, such as the Earthquake Research Institute, University of Tokyo. These experiments provide calibrated (yield, time, location) long-range acoustic transmissions, which enable one to examine the physics of long-range acoustic propagation and to verify the capabilities of the CTBTO IMS network to detect even small explosions.The two IMS stations used are H03 (Juan Fernandez Island, Chile) off the coast of Chile in the Southeastern Pacific and H11 (Wake Island, USA) in the Western Pacific. Both stations consist of two triplets of hydrophones in the SOFAR channel, which monitor the oceans for signs of nuclear explosions. H03 detected low-yield explosions above flat terrain at distances of 15,000 km across the Pacific as well as explosions above the landward slope off the coast of Japan at distances above 16,000 km across the Pacific. These records showed that source signatures, such as short duration and bubble pulses, were preserved over the long propagation distances. It was found that the observed maximum amplitudes from each source exhibit order of magnitude variations even when the yield and detonation depth are the same. The experimental data and transmission loss simulations suggest that bathymetric features around the sources and between the sources and the receivers are the main causes for

Ok, Efe A

2011-01-01

There are many mathematics textbooks on real analysis, but they focus on topics not readily helpful for studying economic theory or they are inaccessible to most graduate students of economics. Real Analysis with Economic Applications aims to fill this gap by providing an ideal textbook and reference on real analysis tailored specifically to the concerns of such students. The emphasis throughout is on topics directly relevant to economic theory. In addition to addressing the usual topics of real analysis, this book discusses the elements of order theory, convex analysis, optimization, correspondences, linear and nonlinear functional analysis, fixed-point theory, dynamic programming, and calculus of variations. Efe Ok complements the mathematical development with applications that provide concise introductions to various topics from economic theory, including individual decision theory and games, welfare economics, information theory, general equilibrium and finance, and intertemporal economics.

The goals of the study included empirical examination of the utility of the Immediate and Post-Concussion Assessment and Cognitive Testing (ImPACT) test with adolescents who are deaf or hard-of-hearing and to investigate patterns of performance at baseline that may arise in the assessment of this population. Baseline assessment of student-athletes has been conducted on a widespread scale with focus on performance of typically developing student-athletes and some clinical groups, though to date no studies have examined adolescents who are deaf or hard-of-hearing. Retrospective and de-identified ImPACT baseline test used with deaf and hard-of-hearing high-school student-athletes (N = 143; 66% male, mean age = 16.11) was examined. Review indicated significant differences in some composite scores between the deaf and hard-of-hearing group and hearing normative comparisons. A possible marker of task misunderstanding was identified to occur more frequently within the deaf and hard-of-hearing sample (13% in deaf sample vs. .31% in hearing sample). Results may provide support for the consideration and use of additional measures to ensure comprehension of task demands when considering this tool for use with deaf and hard-of-hearing adolescents.

Due to its biomimetic mechanical properties to soft tissues, excellent biocompatibility and biodegradability, poly (glycerol sebacate) (PGS) has emerged as a representative bioelastomer and been widely used in biomedical engineering. However, the typical curing of PGS needs high temperature (>120 °C), high vacuum (>1 Torr), and long duration (>12 h), which limit its further applications. Accordingly, we designed, synthesized and characterized a photo/thermo dual curable polymer based on PGS. Treatment of PGS with 2-isocyanatoethyl methacrylate without additional reagents readily produced a methacrylated PGS (PGS-IM). Photo-curing of PGS-IM for 10 min at room temperature using salt leaching method efficiently produced porous scaffolds with a thickness up to 1 mm. PGS-IM was adapt to thermo-curing as well. The combination of photo and thermo curing provided a further way to modulate the properties of resultant porous scaffolds. Interestingly, photo-cured scaffolds exhibited hierarchical porous structures carrying extensive micropores with a diameter from several to hundreds micrometers. All the scaffolds showed good elasticity and biodegradability. In addition, PGS-IM exhibited good compatibility with L929 fibroblast cells. We expect this new PGS based biomaterial will have a wide range of biomedical applications.

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all types of nuclear explosions. For verification of compliance with Treaty the International Monitoring System (IMS) is being built up by the Provisional Technical Secretariat (PTS) of the CTBT-Organisation in Vienna. The IMS observes waveform signals (seismic, infrasound, hydroacoustic) of explosions and traces of radionuclides in the atmosphere to proof the nuclear character of an event. The International Data Centre (IDC) provides analysis products for the IMS data such as various event bulletins, radionuclide reports, and atmospheric transport modeling (ATM) results confining the possible source region of detected radionuclides. The judgment on the character of a suspicious event remains with the member states. The German National Data Centre for verification of CTBT is hosted by the Federal Institute for Geosciences and Natural Resources (BGR) in Hannover. The BGR operates four IMS stations (IS26, IS27, PS19, and AS35) and cooperates closely with the Federal Office for Radiation Protection (BfS) who operates the radionuclide station RN33 at mount Schauinsland and supports the NDC with radionuclide expertise. In response to the Fukushima accident caused by the large magnitude 9.0 Tohuku Earthquake and Tsunami the HSYSPLIT model driven by 0.5 degree NCEP data was used at the German NDC to simulate the primary transport pathways of potentially emitted radioisotopes. The analysis focuses on arrival times and dilution ratios at the radionuclide stations of the IMS. The arrival times were predicted correctly at most stations for ten days after the accident. Traces of the Fukushima emissions were detected at all IMS radionuclide stations on the Northern Hemisphere end of March. In April also some stations on the Southern Hemisphere detected some traces which passed the ITCZ. In respect to the CTBT context the influence of the Tohoku earthquake and the Fukushima emissions on the network capability to detect a

The Global Detection Capability of the IMS Seismic Network in 2013 Inferred from Ambient Seismic Noise Measurements

Gaebler, P. J.; Ceranna, L.

All nuclear explosions - on the Earth's surface, underground, underwater or in the atmosphere - are banned by the Comprehensive Nuclear-Test-Ban Treaty (CTBT). As part of this treaty, a verification regime was put into place to detect, locate and characterize nuclear explosion testings at any time, by anyone and everywhere on the Earth. The International Monitoring System (IMS) plays a key role in the verification regime of the CTBT. Out of the different monitoring techniques used in the IMS, the seismic waveform approach is the most effective technology for monitoring nuclear underground testing and to identify and characterize potential nuclear events. This study introduces a method of seismic threshold monitoring to assess an upper magnitude limit of a potential seismic event in a certain given geographical region. The method is based on ambient seismic background noise measurements at the individual IMS seismic stations as well as on global distance correction terms for body wave magnitudes, which are calculated using the seismic reflectivity method. From our investigations we conclude that a global detection threshold of around mb 4.0 can be achieved using only stations from the primary seismic network, a clear latitudinal dependence for the detection thresholdcan be observed between northern and southern hemisphere. Including the seismic stations being part of the auxiliary seismic IMS network results in a slight improvement of global detection capability. However, including wave arrivals from distances greater than 120 degrees, mainly PKP-wave arrivals, leads to a significant improvement in average global detection capability. In special this leads to an improvement of the detection threshold on the southern hemisphere. We further investigate the dependence of the detection capability on spatial (latitude and longitude) and temporal (time) parameters, as well as on parameters such as source type and percentage of operational IMS stations.

Development of a measuring and evaluation method for X-ray analysis of residual stresses in the surface region of polycrystalline materials; Entwicklung eines Mess- und Auswerteverfahrens zur roentgenographischen Analyse des Eigenspannungszustandes im Oberflaechenbereich vielkristalliner Werkstoffe

The topic of the habilitation thesis is the development of an X-ray diffraction method for measurement and depth-resolved analysis of internal stresses in the surface region of polycrystalline materials. The method relies on the basic approach of varying {tau}, the penetration depth of the X-rays in the materials, by the scattering vector g{sub theta{psi}} via stepwise specimen rotation. Thus, depth profiles of the interlattice plane distances d(hkl) in the specimen system can be derived for given direction and inclination angles {theta} and {psi} of the scattering vector. This offers the possibility to identify individual components of the stress tensors of the basic equation of the X-ray diffraction analysis, and to perform separate analyses of those components. For calculation of the relevant internal stress distributions {sigma}{sub ij}({tau}) using the interlattice plane distance profiles, a self-consistent method is established which takes into account the high sensitivity of the derived internal stresses in relation to the interlattice plane distance d{sub 0}(hkl) in the stress-free crystal lattice. The evaluation yields results describing the depth profiles as well as the strain-free interlattice plane distance d{sub 0}(hkl), so that a quantitative analysis is possible of tri-axial internal stress states in the surface region of the materials. (orig./CB) [German] Den Gegenstand der vorliegenden Arbeit bildet die Entwicklung eines roentgenographischen Mess- und Auswerteverfahrens zur tiefenaufgeloesten Analyse des oberflaechennahen Eigenspannungszustandes in vielkristallinen Werkstoffen. Der Grundgedanke der Methode besteht darin, die Eindringtiefe {tau} der Roentgenstrahlung in den Werkstoff durch schrittweise Drehung der Probe um den Streuvektor g{sub {theta}}{sub {psi}} zu variieren. Damit koennen Tiefenprofile der Netzebenenabstaende d(hkl) fuer fest vorgegebene Azimut- und Neigungswinkel {theta} und {psi} des Streuvektors im Probensystem ermittelt

In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

Long-term liablities of coal mining; Ewigkeitslasten im Kohlenbergbau

Energy Technology Data Exchange (ETDEWEB)

The closer the end of coal mining in 2018, the more the issue of groundwater re-emergence in the Ruhr area is also being considered. This is especially the case because currently the subject of restitution and liability issues in the area of contaminated sites of the peaceful use of nuclear energy is discussed. In addition, the companies concerned lost considerable value on the stock market. For this reason, the question of whether the financial provisions in the created foundation are sufficient to shoulder the expected responsibilities and measures also arises with regard to coal mining. The question is which measures are to be taken and where damages can occur. Additional impulses are given by the Meggen judgment of the BVerwG of 18.12.2014, which interpreted the responsibility of the mining companies very widely. In the Rhineland, an earthquake hit 2.4 on 22.12.2015 - probably due to a rise in groundwater around the closed opencast mine Bergheim. All these questions are included in the colloquium on economics and environmental law on 26 January 2016. This also includes experiences and problems from other federal states such as Brandenburg and Saxony. [German] Je naeher das Ende des Steinkohlenbergbaus 2018 rueckt, desto eher geraet auch die Frage des Grundwasserwiederanstiegs im Ruhrgebiet ins Blickfeld. Das gilt zumal deshalb, weil aktuell ueber Rueckstellung und Haftungsfragen im Bereich der Altlasten der friedlichen Nutzung der Kernenergie diskutiert wird. Zudem verloren die betroffenen Gesellschaften an der Boerse erheblich an Wert. Daher stellt sich auch in Bezug auf den Steinkohlenbergbau die Frage, ob die finanziellen Rueckstellungen in der geschaffenen Stiftung ausreichen, um die zu erwartenden Verantwortlichkeiten und Massnahmen schultern zu koennen. Vorgelagert ist die Frage, welche Massnahmen zu ergreifen sind und wo Schaeden auftreten koennen. Zusaetzliche Impulse bekommt diese Frage durch das Meggen-Urteil des BVerwG vom 18.12.2014, welches die

Application of nuclear activation analysis

International Nuclear Information System (INIS)

Mamonov, E.I.; Khlystova, A.F.

1979-01-01

Consideration is given to the applications of nuclear-activation analysis (NAA) as discussed at the International Conference of 1977. One of the new results in the present-day NAA practices is the growing number of elements detected in samples without using a destructive radiochemical separation. An essential feature in this context is the development of the system automation of control and information NAA operations through the use computers. In biological medicine a multicomponent NAA is employed to determine the concentration of elements in various human organs and objects, in metabolic studies and for diagnostic purposes. In agriculture NAA finds applications in the evaluation of grain protein, analysis of element feed composition, soil and fertilizers. The application of this method to the environmental monitoring is considered with particular reference to the element analysis of water (especially drinking water), air, plant residues. Data are presented for the use of NAA in metallurgy, geology, archaeology and criminal law. Tables are provided to illustrate the uses of NAA in various fields

The report presents a summary of the project of the above title (EFAS project). While earlier projects focused on the technical side, EFAS is the first to present a systematic analysis, presentation and evaluation of the parameters influencing driving support systems. With the aid of a systemic analysis, the key influencing factors are defined and analyzed, and three scenarios are developed which take account of user-oriented, organizational, operational, technical, infrastructural and legal aspects. The scenarios are evaluated with the aid of driving and traffic simulations in the fields of humans, organization and technology, and actions are recommended on this basis for driving support systems in cargo transport. [German] Der Bericht fasst die Ergebnisse des Projektes ''Einsatzszenarien fuer Fahrerassistenzsysteme im Gueterverkehr'' (EFAS) zusammen. Bisher wurde die Thematik Fahrerassistenzsysteme hauptsaechlich auf der Seite der Fahrzeugtechnik vorangetrieben. Das Projekt EFAS stellt nun zum ersten Mal eine umfassende Analyse, Darstellung und Bewertung dar. Mit Hilfe einer systemischen Analyse werden die wesentlichen Einflussfaktoren fuer die Einbindung von Fahrerassistenzsystemen in das Gesamtsystem ''Verkehr'' bestimmt und untersucht. Hieraus werden drei Einsatzszenarien entwickelt, die nutzerbezogene, organisatorische, betriebliche, fahrzeugtechnische, infrastukturelle und rechtliche Aspekte zu Zukunftsbildern zusammenfuegen. Die Szenarien werden mit Hilfe von Fahr- und Verkehrssimulationen in den Bereichen Mensch, Organisation und Technik bewertet. Aus den Ergebnissen werden konkrete Handlungsempfehlungen fuer den Einsatz von Fahrerassistenzsystemen im Strassengueterverkehr abgeleitet. (orig.)

Scalable design of an IMS cross-flow micro-generator/ion detector

International Nuclear Information System (INIS)

Ortiz, Juan J; Nigri, Christian; Lasorsa, Carlos; Ortiz, Guillermo P

2013-01-01

Ion-mobility spectrometry (IMS) is an analytical technique used to separate and identify ionized gas molecules based on their mobility in a carrier buffer gas. Such methods come in a large variety of versions that currently allow ion identification at and above the millimeter scale. Here, we present a design for a cross-flow IMS method able to generate and detect ions at the sub-millimeter scale. We propose a novel ion focusing strategy and test it in a prototype device using nitrogen as a sample gas, and also with simulations using four different sample gases. By introducing an original lobular ion generation localized to a few ten of microns and substantially simplifying the design, our device is able to keep constant laminar flow conditions for high flow rates. In this way, it avoids the turbulences in the gas flow, which would occur in other ion-focusing cross-flow methods limiting their performance at the sub-millimeter scale. Scalability of the proposed design can contribute to improve the resolving power and resolution of currently available cross-flow methods. (paper)

The German Umweltbundesamt (federal environmental agency) commissioned a cost-benefit analysis to be made, testing the practical performance of fuel cell-driven automobiles, for state-of-the-art assessment of their benefits and drawbacks as compared to other available automotive fuel systems. Results available so far of calculations based on the cost-benefit analysis show that the targets involved, such as cutback of emissions and conservation of resources, can be realised within the foreseeable future at much lesser expense through the use of fuel consumption-optimized Otto engines offering lowest emission levels (of the type ULEV, ultra-low emission vehicle, or EURO 4 standard), as compared to the relevant contributions to emission reduction and other targets offered by the fuel cell-driven automobiles.(orig./CB) [Deutsch] Das Umweltbundesamt hat die Brennstoffzellentechnik im Verkehr einer Kosten-Nutzen-Betrachtung unterzogen, um zu ermitteln, welche Vor- und Nachteile sie im Vergleich zu anderen Antriebskonzepten im Verkehr nach derzeitigem Wissensstand hat.

The Titan Orbiter Aerorover Mission (TOAM) is a proposed concept for the Solar System Exploration Visions Mission, Titan Explorer, a follow-on to the Cassini-Huygens mission. TOAM would use a Titan polar orbiter and a lighter-than-air aerorover to investigate the surface and atmosphere of Titan. Astrobiology issues will be addressed though TOAM investigations including, for example: Distribution and composition of organics (atmospheric, aerosol, surface); Organic chemical processes, their chemical context and energy sources; and Seasonal variations and interactions of the atmosphere and surface. The TIDE instrument will perform in-situ analyses to obtain comprehensive and sensitive molecular and elemental assays of volatile organics in the atmosphere, oceans and surface. TIDE chemical analyses are conducted by a Gas Chromatograph-Ion Mobility Spectrometer (GC-IMS). This TIDE GC-IMS was a component of the mini-Cometary Ice and Dust Experiment (mini-CIDEX) developed for the chemical analysis of a cometary environment. Both the GC and helium IMS of mini-CIDEX have been further developed to better meet the analytical and operational requirements of the TOAM. application. A Micro-ElectroMechanical System (MEMS) GC and Mini-Cell helium IMS are under development to replace their respective mini-CIDEX components, providing similar or advanced analytical capabilities.

In the initial experiment after the increase of the power of ohm heating power source for the superconducting strong magnetic field tokamak, TRIAM-IM, the measurement of the electron temperature distribution, ion temperature distribution and beam average electron density of ohm-heated plasma was carried out. By analyzing the experimental results, the dependence of the accumulated energy obtained from the temperature distribution and the time of energy confinement of beam average electron density became clear. Especially the time of energy confinement increased in proportion to the increase of beam average electron density when it is 6.5 x 10 12 /m 2 , and it was found that the time of energy confinement conforms to the Neo-Alcator proportional law. Moreover, by solving the heat transport equation for ions, the radial distribution of thermal diffusion coefficient for ions was calculated, and compared with that obtained by the new classic theory. As the result, it was found that the TRIAM-IM has ion confinement characteristics equivalent to those of other medium tokamaks. The experiment of producing ohm-heated plasma, the fitting of electron temperature and ion temperature, the density dependence of temperature, accumulated energy and the time of energy confinement, the time of energy confinement and the Neo-Alcator proportional law, the energy balance of ions and so on are reported.

This paper reviews the activities at OKSI related to imaging spectroscopy presenting current and future applications of the technology. The authors discuss the development of several systems including hardware, signal processing, data classification algorithms and benchmarking techniques to determine algorithm performance. Signal processing for each application is tailored by incorporating the phenomenology appropriate to the process, into the algorithms. Pixel signatures are classified using techniques such as principal component analyses, generalized eigenvalue analysis and novel very fast neural network methods. The major hyperspectral imaging systems developed at OKSI include the Intelligent Missile Seeker (IMS) demonstration project for real-time target/decoy discrimination, and the Thermal InfraRed Imaging Spectrometer (TIRIS) for detection and tracking of toxic plumes and gases. In addition, systems for applications in medical photodiagnosis, manufacturing technology, and for crop monitoring are also under development.

Speed sensorless direct torque control of IMs with rotor resistance estimation

International Nuclear Information System (INIS)

Barut, Murat; Bogosyan, Seta; Gokasan, Metin

2005-01-01

Direct torque control (DTC) of induction motors (IMs) requires an accurate knowledge on the amplitude and angular position of the controlled flux in addition to the information related to angular velocity for velocity control applications. However, unknown load torque and uncertainties related to stator/rotor resistances due to operating conditions constitute major challenges for the performance of such systems. The determination of stator resistance can be performed by measurements, but methods must be developed for estimation and identification of rotor resistance and load torque. In this study, an EKF based solution is sought for determination of the rotor resistance and load torque as well as the above mentioned states required for DTC. The EKF algorithm used in conjunction with the speed sensorless DTC is tested under eleven scenarios comprised of various changes made in the velocity reference beside the load torque and rotor resistance values assigned in the model. With no a priori information in the estimated states and parameters, it has been demonstrated that the EKF estimation and sensorless DTC perform quite well in spite of the uncertainties and variations imposed on the system

2012-01-01

A framework for the multiscale design and analysis of composite materials and structures is presented. The ImMAC software suite, developed at NASA Glenn Research Center, embeds efficient, nonlinear micromechanics capabilities within higher scale structural analysis methods such as finite element analysis. The result is an integrated, multiscale tool that relates global loading to the constituent scale, captures nonlinearities at this scale, and homogenizes local nonlinearities to predict their effects at the structural scale. Example applications of the multiscale framework are presented for the stochastic progressive failure of a SiC/Ti composite tensile specimen and the effects of microstructural variations on the nonlinear response of woven polymer matrix composites.

We study the two-dimensional affine Toda field equations for affine Lie algebra g{sup ^} modified by a conformal transformation and the associated linear equations. In the conformal limit, the associated linear problem reduces to a (pseudo-)differential equation. For classical affine Lie algebra g{sup ^}, we obtain a (pseudo-)differential equation corresponding to the Bethe equations for the Langlands dual of the Lie algebra g, which were found by Dorey et al. in study of the ODE/IM correspondence.

The heat energy which is released when generating power at the temperature level >100 C - which is favourable for heating purposes - serves directly for heat supply or the driving a refrigerating machine/heat pump for the supply of cooling energy in summer and low-temperature heat in winter. As the demand on heat and power supply often will not be parallel, there will be a temporary surplus of heat offered by the motor-driven power station, and at other times it will be deficient. That is why surplus heat from the motor-driven power station is stored in a deep aquifer heat reservoir for recovery and utilisation for heating in winter. By using a geothermal saline water reservoir, the waste heat from the motor-driven power station can be fed into it at a temperature level ranging from 60.. 80 C and recovered and utilised at a temperature level ranging from 60.. 20 C. A shallow groundwater aquifer cold storing reservoir serves for cooling: the cold stored in winter is supplied in summer to the cooling equipment of the building by direct cooling with the cold water form the aquifer (heat exchange) at a temperature level of 14/15 C. The cooling demand in case of air dehumidification at a temperature level of 6/12 C is covered by a cooling machine which is also cooled with the cold water from the aquifer. As cooling machine/heat pump an environment-friendly, CFC-free absorption machine is used working on a combination of water and lithium bromide. The machine is driven by the waste heat from the motor-driven power plant. (orig.)

Noise Analysis techniques (analysis of the fluctuation of physical parameters) have been successfully applied to the operational vigilance of the technical equipment that plays a decisive role in the production cycle of a very complex industry. Although fluctuation measurements in nuclear installations started almost at the start of the nuclear era (see works by Feynman and Rossi on the development of neutron methodology), only recently have neutron noise diagnostic applications begun to be a part of the standard procedures for the performance of some modern nuclear installations. Following the relevant technical advances made in information sciences and analogical electronics, measuring the fluctuation of physical parameters has become a very effective tool for detecting, guarding and following up possible defects in a nuclear system. As the processing techniques for the fluctuation of a nuclear reactor's physical-neutron parameters have evolved (temporal and frequency analysis, multi-parameter self -regression analysis, etc.), the applications of the theory of non-lineal dynamics and chaos theory have progressed by focusing on the problem from another perspective. This work reports on those nuclear applications of noise analysis that increase nuclear safety in all types of nuclear facilities and that have been carried out by the author over the last decade, such as: -Void Force Critical Set Applications (Zero Power Reactor Applications, Central Institute of Physical Research, Budapest, Hungary); -Research Reactor Applications (Triga Mark III Reactor, National Institute of Nuclear Research, ININ, Mexico); -Power Reactor Applications in a Nuclear Power Plant (First Circuit of Block II, Paks Nuclear Center, Hungary); -Second Loop applications in a Nuclear Power Plant (Block I Paks Nuclear Center, Hungary; Block II Kalinin Nuclear Center, Russia); -Shield System Applications for the Transport of Radioisotopes (Nuclear Technology Center, Havana, Cuba) New trends in
