    Transport systems of the future will be more efficient and less polluting than the current systems. Intermodal transport is an interesting alternative, i.e. truck/railway or truck/ship systems. In spite of extensive state funding, systems of this type still fail to meet the standards to make them competitive. The contribution compares monomodal and intermodal systems and attempts to defines strategies to make intermodal systems more successful. [German] Vor dem Hintergrund des in den vergangenen Jahren kontinuierlich gestiegenen Verkehrsaufkommens und den damit in engem Zusammenhang stehenden Umweltproblemen sind fuer die Zukunft leistungsfaehige Transportsysteme gefordert, die eine weiter wachsende Verkehrsnachfrage im Vergleich zu den zur Zeit im Einsatz befindlichen Systemen umweltvertraeglicher abwickeln. Eine aussichtsreiche Alternative stellt in diesem Zusammenhang der Kombinierte Verkehr (KV) als intermodale Verkehrsform von Lkw und Eisenbahn bzw. Schiff dar. Trotz einer Vielzahl in der Vergangenheit erfolgter staatlicher Foerdermassnahmen fehlt es dem KV nach wie vor in vielen Bereichen an der noetigen Wettbewerbsfaehigkeit, was sich in einem entsprechend niedrigen Marktanteil am Gueterverkehrsmarkt niederschlaegt. Im vorliegenden Beitrag wird dieser bei vordergruendiger Betrachtung zunaechst als Widerspruch anmutende Sachverhalt im Rahmen einer vergleichenden Analyse von verschiedenen monomodalen Transportsystemen und dem KV untersucht. Die dabei ermittelten Ergebnisse dienen im weiteren als Ausgangspunkt zur Diskussion von Ansaetzen, die ein modernes betriebliches Informationsmanagement im Hinblick auf eine Verbesserung der Akzeptanz des KV bietet.

    If both mobility and space for living are to be assured in Europe during the 21st century, concepts must be developed which make mobility both economically and ecologically acceptable. The book provides an introduction to information management in transportation. It is based on a model which views information management at different levels. On this basis, supporting applications of information and communication technologies can be formulated on the basis of economic and decision-oriented requirements. The book focuses on the necessary functionalities of these applications and the necessary infrastructure. Practical examples are presented from the fields of public transport, individual motor car transport and cargo transport. [German] Sollen Mobilitaet und Lebensraum im Europa des 21. Jahrhunderts erhalten bleiben, so sind Konzepte gefordert, die einen Beitrag zur wirtschaftlichen und oekologisch vertretbaren Mobilitaetsbewaeltigung leisten. Das Buch bietet hierzu einen umfassenden Einstieg in das Informationsmanagement im Verkehr. Ausgehend von Ueberlegungen zu einem Ebenenmodell des Informationsmanagements lassen sich aus betriebswirtschaftlichen und entscheidungsorientierten Anforderungen Unterstuetzungsleistungen ableiten, die unter Vewendung geeigneter Informations- und Kommunikationstechnologien zu erbringen sind. Im Vordergrund der Betrachtungen stehen die zu fordernden Funktionalitaeten an entsprechende Applikationen und die hierfuer benoetigte Infrastruktur. Anhand von Beispielen aus der Praxis werden Anwendungen aus den Bereichen oeffentlicher Personenverkehr, motorisierter Individualverkehr und Gueterverkehr vorgestellt. (orig.)

    The progress in our understanding of plasma processes throughout the magnetosphere has increased dramatically during the International Magnetospheric Study (IMS) period. In this report the auroral ionosphere as a source of particles for the magnetosphere and the auroral particle acceleration and precipitation are emphasized. Some of the processes involved in the transport of particles from the ionosphere out into the magnetosphere are treated as well as the precipitation of magnetospheric particles into the auroral and subauroral ionosphere. Some of the effects auroral ionospheric ions have on the magnetospheric plasma composition are described. A brief overview of pre-IMS results is also given to set the stage for a description of IMS contributions in these areas.

    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.)

  6. Mechanisms of meridional transport processes in the tropical Atlantic; Mechanismen meridionaler Transportprozesse im tropischen Atlantik

    Energy Technology Data Exchange (ETDEWEB)

    Kroeger, J.

    2001-07-01

    Meridional transport processes of water masses and tracers in the subtropical and tropical Atlantic are investigated using a regional eddy resolving model of the wind driven and thermohaline circulation. Analytical emphasis is on float simulations in the model which, complementary to Eulerian means, represent the Lagrangian view and give further insight into the spreading and pathways of characteristic water masses in this area. In the tropics and subtropics shallow 3-dimensional circulation cells are superimposed on the northward warm water transfer within the deep reaching thermohaline overturning cell (MOC) as part of the global ''Conveyor Belt''. Under present-day climate conditions the model shows that the equatorial thermocline is exclusively ventilated by subsurface flow within the tropical-subtropical cell (STC) of the South Atlantic. Only with a prescribed ''Conveyor-off''-Mode the STC of the North Atlantic contributes to this ventilation process with equal amounts. Throughout the year the interhemispheric transport of surface and central water masses of South Atlantic origin into the Caribbean Sea is dominated by zonal detours to the east as a consequence of the interplay of several retroflection events occuring in the North Atlantic. The eulerian mean flow field in the deep layer postulates the interhemispheric mass transport into the South Atlantic to be confined entirely to the western boundary, whereas Lagrangian means indicate intermittent eastward excursions along the equator, related to seasonally alternating zonal currents due to long Rossby waves. It was suggested that the observed characteristic eastward maximum of tracer concentrations along the equator is a consequence of rectifying effects of single or interacting equatorial waves. The model does not validate this hypothesis. The response to transport anomalies of subpolar origin and long periodicity is subject to different time-scales in both

    Colloids, i.e. particulates of 1 nm to 1 {mu}m suspended in water, are found in all types of groundwater, either as organic colloids, inorganic colloids, or mixtures of both. Their concentration, chemical composition, structure and particle size varies with the geochemistry of the sediment-water system. Inorganic colloids are Al-Fe-Mn mixed oxides, clays and other complex minerals. Organic colloids consist of humic and fulvic acids which are the main constituent of the dissolved organic carbon. Humic acids are capable of forming metal humate complexes with metal ions via proton-exchanging groups. Radionuclides, too, are transported with humic acid, especially trivalent and multivalent metal ions of the lanthanides and actinides as well as radio-iodine. [German] In allen Grundwaessern werden Kolloide, d.h. im Wasser suspendierte Teilchen mit Durchmessern im Bereich 1 nm bis 1 {mu}m gefunden. Die Zusammensetzung der Kolloide kann sowohl organischer als auch anorganischer Natur sein, wobei in vielen Grundwaessern eine Mischung beider Kolloidarten auftritt. Die Konzentration, die chemische Zusammensetzung, die Struktur und die Teilchengroesse natuerlicher Kolloide variieren stark, sie sind abhaengig von der Geochemie des Sediment-Wasser-Systems. Anorganische Kolloide sind Al-Fe-Mn-Mischoxide, Tone and andere komplexe Mineralien. Organische Kolloide bestehen aus Humin- und Fulvinsaeuren; diese Huminstoffe bilden den Hauptbestandteil des geloesten organischen Kohlenstoffs. Eine wichtige Eigenschaft der Huminstoffe ist ihre Faehigkeit, mit Metallionen ueber protonenaustauschende Gruppen Komplexe - sog. Metall-Humate - zu bilden. Auch Radionuklide, insbesondere drei- und mehrwertige Metallionen der Lanthaniden und Actiniden sowie Radio-Iod werden an Huminstoffe gebunden. Damit koennen Radionuklide nicht nur in Form einfacher Spezies, sondern auch huminstoffgebunden transportiert werden. (orig.)

    As far as any business involved in transporting passengers is concerned, it is its timetable of services that has the decisive impact on its competitive situation. An earlier issue of this magazine (11/2005) included a discussion of the characteristics of four timetabling strategies. This article follows on from there by outlining the potential inherent in the use of mathematical optimization procedures. These are shown to be especially significant for the two most relevant strategies of 'even headways' and 'symmetrical even headways', since both have appreciable optimization potential, and powerful procedures exist for both of them too. The author begins by describing the formation of the model, before going on to discuss how it has been used in practice to date, the studies that have been carried out into the conflicting targets of fleet deployment and passenger waiting times, and finally shows in what ways symmetry can be suboptimal.

    In the present study the sediment transport processes in alpine mountain areas and their impact on hydropower development projects are investigated. The aim of the present work is to contribute to the understanding of the transport process system, which is characterized by high magnitude-low frequency - events, to ensure an appropriate layout of high head hydropower projects in mountain regions. The sediment transport in large areas in the macro scale is triggered by natural hazards, such as earthquakes, rock slides, earth movements, debris flows, glacial lake outbursts and floods. The basic principle of complex transport processes in this scale is described and explained on the example of the Himalaya-Karakorum-region. The sediment transport process in the smaller scale, so called meso scale, is investigated by means of extensive field measurements at river reaches of 16 different mountain rivers of a 80000 km{sup 2} large project area. The measurements include topographic survey works and measurements of discharge, bed load and suspended load. Since the conditions of mountain rivers in terms of size of bed material as well as available flow velocities can be considered as extreme, an appropriate bed load sampler named B-69 was developed, constructed and used in the field. Moreover the hydraulic as well as the sedimentological efficiency of the sampler was tested in the laboratory tests. Due to the nice performance of the bed load sampler B-69 at high flow velocities it might be useful for flood conditions in gravel-bed rivers in other parts of the world as well. Based on the results of the study the parameter of the river slope can be considered as the most important one for the characteristics of the morphology, the flow conditions, the bed stability as well as the bed load transport in steep mountain rivers. With increasing slope morphological structures in the longitudinal direction will develop from flat bed conditions. The so called step-pool-systems consist

    In July, 2003, FiFo Koeln (Cologne Centre for Public Economics) was mandated by the German Federal Environmental Agency (UBA) with the examination of the UFOPLAN scheme 'Emissions Trading System for the Transport Sector - Development of a possible Trading Approach'. The main task of this study was the development of a concrete emissions trading approach for the transport sector, which triggers off a compulsory holding of emissions certificates at the beginning of the energy supply chain (upstream approach). The main focus was rather put on the practical options of the implementation of an upstream approach in the transport sector and its specific problems. The transaction costs of a trading system in the transport sector had to be kept at a minimum level. The upsteam approach discussed in his study seems to be more adequate to include further carbon dioxide emissions of other sectors than the EU downstream model. This can mainly be attributed to the amount and nature of the respective transaction costs. In Germany allocative failure in fuel taxation between diesel and petrol can be diminished regardless of the prices for CO{sub 2}. Emissions trading therefore leads to structural changes. An upstream approach has only indirect effects on the motorcar industry and refiners. Therefore, technical CO{sub 2} reduction can primarily be realised via an increased consumer demand for ore fuel-efficient vehicles, new propulsion technology or alternative fuels based on renewable energies. In the case of an open trading system the amount of transport emissions was estimated that actually could be reduced to be relatively small. The authors of the contribution under consideration are not convinced that the full potential of existing adaptation options in the transport sector can be tapped by an open emissions trading. The transport sector will cope with additional CO{sub 2} costs without tapping the potential of relatively cheap adaptation options. Also at closed

    The dispersal of trace substance in groundwater may be limited by dissolution and precipitation and, of particular interest in this paper, by sorption and desorption processes. These surface-active processes, which have a decisive influence on groundwater quality, depend on the concomitant geochemical conditions prevailing in the water, the constituents of the aquifer and on the surface properties of the solids. Taking the geochemical conditions prevailing naturally in brown coal mining areas as a point of departure this study was aimed at examining the influence of acidification processes on the transport behaviour inorganic pollutants for the example of zinc. For this purpose oxic column trials were carried out on sandy aquifer material. The data were supplemented by a detailed characterisation of the solid surfaces and modelled on the basis of a transport-reaction model as well as mechanistically with due regard to surface complexing. [German] Die Ausbreitung von Spurenstoffen im Grundwasser wird ausser durch Loesungs- und Faellungsprozesse vor allem durch Sorptions- bzw. Desorptionsvorgaenge limitiert. Diese fuer die Grundwasserqualitaet entscheidenden oberflaechenaktiven Prozesse sind von den variablen geochemischen Randbedingungen im Wasser, vom Stoffbestand des Aquifers und von den Oberflaecheneigenschaften der Feststoffe abhaengig. In Anlehnung an die natuerlichen im Bereich von Braunkohle-Abbaugebieten herrschenden geochemischen Bedingungen wurde der Einfluss von Versauerungsprozessen auf das Transportverhalten von anorganischen Schadstoffen, am Beispiel von Zink, auf der Basis von oxischen Saeulenversuchen an sandigem Aquifermaterial untersucht. Die Daten wurden durch eine detaillierte Charakterisierung der Feststoff-Oberflaechen ergaenzt und sowohl mit Hilfe eines Transport-Reaktionsmodells als auch mechanistisch unter Einbeziehung der Oberflaechenkomplexierung modelliert.

    The number of mobility aid users continues to rise as the population ages. While mobility aid users rely on public transport due to its affordability, evidence suggests access can be difficult. This study aims to describe people who use mobility aids to access public transport and the role of public transport access in influencing mobility aid choice. Sixty-seven mobility aid users participated in telephone surveys which predominantly used a structured quantitative format. Data were analysed descriptively and any additional comments were simply categorized. Thirty-six participants were female (54%), with a total sample mean age of 58.15 years (SD = 14.46). Seventy-two percent lived in metropolitan areas, 48% lived alone, and the sample experienced a variety of conditions including spinal cord injury (37%) and arthritis (18%). Sixty-four percent of all respondents used two or more mobility aids including powered wheelchairs, scooters and walking frames. The most important features when choosing a mobility aid were reliability, turning ability and size. Fifty-two percent of all respondents strongly agreed that public transport is generally accessible. While work continues to ensure that public transport vehicles and stations are fully accessible, mobility aid users must manage current infrastructure and access a system which has been shown through this research to have many limitations. Mobility aid users, vendors and health professionals need to work together to identify mobility aids that fulfil needs, and are reliable and safe, so that mobility aid users are both "visible and seen" when accessing the public transport network. Implications for rehabilitation Some mobility aid users experience difficulties accessing and using public transport and further research is required to ensure the whole public transport network is fully accessible to people using mobility aids. Many people have more than one seated mobility aid, suggesting people can choose different

    The management of proton conductivity in the protic ionic liquid imidazolium bis(trifluoromethylsulfonyl)imide ([Im][TFSI]) is investigated via the use of quasi-elastic neutron scattering (QENS) and pulsed-field gradient NMR. The introduction of excess neutral imidazole to [Im][TFSI] leads to enhanced conductivity. We find that proton dynamics in [Im][TFSI] with excess imidazole are characterized by proton hopping that is encompassed in the slower of two translational processes, as identified by QENS. This relatively slow process contributes to long-range diffusion more than the faster process. NMR diffusion measurements show that proton hopping decreases with increasing temperature, but significant proton hopping persists even at the maximum experimental temperature of 120 °C. This, in combination with minimal ion aggregation, leads to high proton conductivity and a high proton transference number over a wide temperature range.

    Reliability evaluation of systems has been widely researched for improving system resilience especially in designing processes of a complex system. The convergence of different access networks is possible via IP Multimedia Subsystem (IMS) for development toward Next Generation Networks (NGNs......) and supporting always on services. Therefore, not only Quality of Service (QoS) but also resilience is required. In this paper, we attempt to evaluate and analyze end-to-end reliability of the IMS system using a model proposed as a combination of Reliability Block Diagram (RBD) and Markov Reward Models (MRMs......). The resilience of the IMS architecture is studied by applying 1:1 redundancy at different communication scenarios between end users within and across communication domains. The model analysis provides useful reliability characteristics of the system and can be further applied for system design processes....

    In the year just started significant decisions with considerable consequences by the Federal Constitutional Court and the Federal Administrative Court in the field of nuclear law are expected. Especially the decision with regards to 'nuclear phase-out' within the 13th amendment of the Atomic Energy Act is being eagerly expected, as with its far-reaching consequences also fundamental constitutional questions need to be answered. The Federal Administrative Court will need to decide on the question, whether she admits the appeal against the Brunsbuettel decision by the Higher Administrative Court Schleswig-Holstein (HAC), which from the view of claimant shifted the fundamental basis of demarcation of responsibilities between the executive and judiciary power. In comparison to these fundamental decisions the awaited decision by the HAC on nuclear transport legislation seems of subordinate importance, although she will proceed with a paradigm shift in the legal area. The decision deals with the question as to whether and when a right of action from a third party within the nuclear transport legislation can be accepted or more precisely under which preconditions a third party has clear standing against a nuclear transport authorisation. As the site selection law (issued on 23 July 2013 BGBI I p. 2552) excludes the recirculation of vitrified waste block canisters from reprocessing spent fuel elements to the transport cask storage facility Gorleben, the decision by the HAC Lueneburg for this site will only be relevant for present unpredictable transportations from the transport cask storage facility Gorleben to a final repository. If necessary interest to seek a declaratory judgment for declaratory action, in concreto danger of recurrence will be approved, is another matter.

    2003-01-01

    Full Text Available Leptin ist ein in Adipozyten exprimiertes Hormon mit vielfältigen Funktionen im gesamten Organismus. Verschiedene Studien legen eine positive Wirkung von Leptin auf den Knochenstoffwechsel nahe. In vitro führte die Inkubation von Knochenmarkstromazellen mit Leptin zu deren Differenzierung zu Osteoblasten und Mineralisation der Matrix. Bei ovarektomierten Ratten konnte durch Leptin der Knochenverlust vermindert werden. Überraschenderweise zeigten andere Studien eine zentrale inhibitorische Wirkung von Leptin auf Osteoblasten bei Nagern. Diese einander scheinbar widersprechenden Ergebnisse zeigen, daß die molekularen Mechanismen, mit welchen Leptin auf den Knochenstoffwechsel wirkt, noch nicht ausreichend verstanden werden. In klinischen Studien findet sich eine protektive Wirkung von Fettmasse und "body mass index" (BMI auf die Knochendichte (postmenopausaler Frauen überwiegend bestätigt. Damit im Einklang, konnten erhöhte Leptinspiegel gefunden werden. Ob Leptin nun direkt in den Knochenstoffwechsel eingreift oder bloß indirekt etwa über eine erhöhte mechanische Belastung, läßt sich aus klinischen Studien allein nicht beantworten. Hingegen dürfte Leptin im Knochenstoffwechsel von Männern keine oder nur eine untergeordnete Rolle spielen. Die Situation bei Kindern und Jugendlichen ist noch unklar, wobei eine positive Wirkung von Leptin in fetalem Knochen relativ sicher ist. Leptin könnte jedoch auch im Wachstum und der Knochenreifung bei Kindern und Jugendlichen eine Rolle spielen.

  7. Uber Phosphorylierung im Licht

    Während bisher der Zusammenhang zwischen Dehydrierung und Phosphorylierung im Licht nur für die stöchiometrischen Chinonreactionen bewiesen worden war, ist nunmehr auch für die katalytischen Chinonreactionen, die aeroben wie die anaeroben, gezeigt worden, dass die Dehydrierung die Phosphorylierung bewirkt. Eine andere Phosphorylierung, als die Phosphorylierung durch Dehydrierung gibt es in den grünen Grana nicht. Natürlich entsteht nunmehr die Frage, welche Substanz das Substrat von Dehydrierung und Phosphorylierung ist. Da die Grana keine Dunkelatmung haben und deshalb im Dunkeln nicht phosphorylieren können, auch nicht nach Zusatz von Chinon, so muss das gesuchte Substrat im Licht entstehen; und da der Photolyt der Granareactionen eine Kohlensäureverbindung ist, so muss das gesuchte Substrat eine im Licht entstehende Kohlenstoffverbindung sein. Wegen der Gärungen und dem einzigen bisher bekannten chemischen Mechanismus der Phosphorylierung durch Dehydrierung (4) denkt man an Triosephosphat. Aber chemisch ist jeder Aldehyd möglich.

    Full Text Available Gemeinsam von Künstlern und Wissenschaftlern/Philosophen erstellte Bücher sind selten und nicht immer erfolgreich. Eines der Fährnisse ist das Verhältnis zwischen bildlichen und schriftlichen Anteilen: Nicht selten wird der künstlerische Anteil zur Illustration der dominierenden Schrift. Eine Neupositionierung des Bildes im Buch ist nun der amerikanischen Künstlerin Roni Horn gelungen. Mehr als „sujet“ ihres Buches, ist die französische Philosophin Hélène Cixous gleichsam instruierende „Stimme“, die im Bild aufscheint. Horn hat dadurch zugleich – einmal mehr – das Phantasma unmittelbarer Abbildhaftigkeit des Fotos dekonstruiert und der philosophischen Position Cixous‘ durch das Bild eine Dimension hinzugefügt.

    In den stark automatisierten, arbeitsteiligen Wirtschaftsystemen der Industrienationen ist die eine effiziente und zuverlässige zentrale Informationstechnik (IT) der Unternehmen entscheidend für den Geschäftserfolg. Immer mehr Unternehmensabläufe werden durch die IT unterstützt. Vielfach ist es sogar nur noch durch die umfassende IT-Unterstützung der Geschäftsprozesse möglich, im globalen Wettbewerb erfolgreich zu sein. Die installierte Rechenleistung in modernen Unternehmen steigt dabei ständig an. Neue und verbesserte Anwendungen und Programm-Features erfordern leistungsfähige Server. In den Rechenzentren kleiner und mittlerer Unternehmen sind heute Rechenleistungen installiert, die vor wenigen Jahren ausschließlich einigen Großunternehmen vorbehalten waren. Diese im Grundsatz positive Entwicklung kann aber auch zu hohen Strom- und Kühlleistungen in Rechenzentren führen. Damit stellen sich neue Herausforderungen an die Planung, Ausführung und den Betrieb einer IT-Infrastruktur.

    This report examines the market potential of a miniature, hand-held Ion Mobility Spectrometer. Military and civilian markets are discussed, as well as applications in a variety of diverse fields. The strengths and weaknesses of competing technologies are discussed. An extensive Ion Mobility Spectrometry (IMS) bibliography is included. The conclusions drawn from this study are: (1) There are a number of competing technologies that are capable of detecting explosives, drugs, biological, or chemical agents. The IMS system currently represents the best available compromise regarding sensitivity, specificity, and portability. (2) The military market is not as large as the commercial market, but the military services are more likely to invest R and D funds in the system. (3) Military applications should be addressed before commercial applications are addressed. (4) There is potentially a large commercial market for rugged, hand-held Ion Mobility Spectrometer systems. Commercial users typically do not invest R and D funds in this type of equipment rather, they wait for off-the-shelf availability.

Im Falle des Altgriechischen hätte man eigentlich wenig zu beklagen, denn es mangelt nicht an Material, dazu sind die Texte, die uns zur Verfügung stehen, stilistisch und funktionell verschiedenartig. Es gibt mehrere Gründe, Wortstellung im Altgriechischen zu untersuchen: stilistische Eigenschaften, das Neugriechische sowie das Verhältnis des Altgriechischen zum Indogermanischen. Es liegt zwar auf der Hand, die Untersuchung auf typologischer Grundlage durchzuführen, die Feststellungen, zu denen man auf diese Weiße gelangt, sind jedoch selten schlüssig. Es ist demnach alles andere als leicht, mit solchen Forschungen zuverlässige Ergebnisse zu erzielen. Die erhaltenen Texte können einen 'native speaker' selbstverständlich nicht ersetzen, zumal die griechischen Grammatiker die Syntax oft bei Seite ließen und die Wortstellungsvarianten der Lehre über den Stil überließen. Ein derartiges Beispiel bieten uns Aristoteles' Poetik und die Abhandlung De compositione verborum des Dionysios von Halikarnaß.Es dürfte uns also kaum überraschen, wenn die Forschungen des 19. und 20.

    The development of a new ion mobility/mass spectrometry instrument that incorporates a multifield drift tube/ion funnel design is described. In this instrument, individual components from a mixture of ions can be resolved and selected on the basis of mobility differences prior to collisional activation inside the drift tube. The fragment ions that are produced can be dispersed again in a second ion mobility spectrometry (IMS) region prior to additional collisional activation and MS analysis. The result is an IMS-IMS analogue of MS-MS. Here, we describe the preliminary instrumental design and experimental approach. We illustrate the approach by examining the highly characterized bradykinin and ubiquitin systems. Mobility-resolved fragment ions of bradykinin show that b-type ions are readily discernible fragments, because they exist as two easily resolvable structural types. Current limitations and future directions are briefly discussed.

  19. Pulsation research during the IMS

    1982-08-01

    Workers in the pulsation field entered the period of the International Magnetospheric Study (IMS) with a lot of theories that needed testing. Because of this and the wealth of new data available from the IMS observational campaigns, many new observational results have emerged from the IMS. The experience of the IMS shows us that the most fruitful method of working has been small-scale collaborations, between either a few individuals or a few groups with complementary data sets. The larger, more formally organized workshops do not seem to have been as successful in producing results, though they may have fostered useful contacts. In the years to come I hope and expect to see more of this sort of small-scale collaboration; especially as the initial results obtainable from a single data set are now published, experiments should turn to seeing how their data can be used in conjunction with other data sets. I also feel that the time is ripe for more theoretical work. The IMS has left us with a lot of new observations that need explanation.

    In a cooperation project of the Geoscience and Geography Department of TU Darmstadt Technical University and the Leipzig-Halle Environmental Research Center (UFZ), potential transport pathways of organic pollutants from the lake into the groundwater aquifers were investigated. Drill profiles, mining sections and maps, aerial views and hydroacoustic profiles helped to establish a digital terrain model on the basis of a Geographic Information System and, on this basis, a 3D groundwater flow model including pollutant transport using the FEFLOW code. The model parameters were derived from field tests (slug test, pumping test, seepage meter, level gauging) and laboratory tests (grain size analysis, flow meter cell and sorption tests) as well as from relevant publications. Further, the hydrochemical and isotopic properties of the groundwater and lake water were described. The 3D model was to yield the current hydrogeological knolwedge and to make predictions on the fate, transport or decomposition of the phenols. The future development of groundwater quality can be simulated in order to assess the danger to freshwater wells and provide a basis for assessing the necessity and possibility of groundwater sanitation. The project will serve as a model for the methodology to be employed in similar cases of damage.

    An integrated mobility system (IMS) relies on various innovative technologies to improve urban transportation services, such as smart cards which are charged with a specific dollar amount that is reduced with each payment. Smart cards offer greater speed and convenience of payment for transit trips, increasing transportation system efficiency. This study evaluated the potential environmental impacts of implementing an Integrated Mobility System in the Greater Toronto Area (GTA), with special emphasis on reductions of carbon dioxide. The authors reviewed the experience gained in other jurisdictions and also used a judgement-guided analysis based on current GTA travel behaviour, allowing for the estimation of incremental changes in this behaviour in response to IMS implementation. The different features that might be included in an IMS were defined and their potential impacts on travel behaviour were identified with a particular focus on the shift from driving to transit. The features that are most likely to be included in the GTA IMS were identified. Results of a literature review of IMS-related factors that might have an impact on transit ridership were provided, and the recent empirical experience with IMS-type initiatives in other North American cities were summarized, along with the travel behaviour for the base year (1996) in the analysis. The analysis method used to generate quantitative estimates of IMS environmental impacts was described in detail. 27 refs., 12 tabs., 14 figs.

  6. THOR Ion Mass Spectrometer (IMS)

    2017-04-01

    Turbulence Heating ObserveR (THOR) is the first mission ever flown in space dedicated to plasma turbulence. The Ion Mass Spectrometer (IMS) onboard THOR will provide the first high-time resolution measurements of mass-resolved ions in near-Earth space, focusing on hot ions in the foreshock, shock and magnetosheath turbulent regions. These measurements are required to study how kinetic-scale turbulent fluctuations heat and accelerate different ion species. IMS will measure the full three-dimensional distribution functions of main ion species (H+, He++, O+) in the energy range 10 eV/q to 30 keV/q with energy resolution DE/E down to 10% and angular resolution down to 11.25˚ . The time resolution will be 150 ms for O+, 300 ms for He++ and ˜ 1s for O+, which correspond to ion scales in the the foreshock, shock and magnetosheath regions. Such high time resolution is achieved by mounting four identical IMS units phased by 90˚ in the spacecraft spin plane. Each IMS unit combines a top-hat electrostatic analyzer with deflectors at the entrance together with a time-of-flight section to perform mass selection. Adequate mass-per-charge resolution (M/q)/(ΔM/q) (≥ 8 for He++ and ≥ 3 for O+) is obtained through a 6 cm long Time-of-Flight (TOF) section. IMS electronics includes a fast sweeping high voltage board that is required to make measurements at high cadence. Ion detection includes Micro Channel Plates (MCPs) combined with Application-Specific Integrated Circuits (ASICs) for charge amplification and discrimination and a discrete Time-to-Amplitude Converter (TAC) to determine the ion time of flight. A processor board will be used to for ion events formatting and will interface with the Particle Processing Unit (PPU), which will perform data processing for THOR particle detectors. The IMS instrument is being designed and will be built and calibrated by an international consortium of scientific institutes from France, USA, Germany and Japan and Switzerland.

    The use of nearly sulfur-free diesel fuel results at once in distinctly enhanced exhaust gas values of entire vehicle fleets at relatively small additional cost. Where technically possible, CRT systems can be used, thus substantitally reducing emissions of CO, HC and, especially, soot particles, all of which must meet limiting values. The added cost of a CRT system, about 10000 German Marks, corresponds roughly to 2 per cent of the cost of a new solo vehicle. In addition, there are no accessory costs like, for instance, when operating buses with natural gas (construction of new filling stations, training of personnel, additional safety checks, reconstruction of workshops and depots, etc.).

    The electricity grid that has been used for decades reaches its limits when transporting increasing amounts of electricity over long distances. There are already limiting bottlenecks. One way to integrate more wind and solar power into the grid is provided by overhead lines with a higher maximum temperature. These can transport more electricity, enabling grid congestion to be avoided. One problem, though, is that metals expand more at high temperatures. As a result the line lengthens and sags more. However, special high-temperature conductors can provide a remedy here.

In the first lecture, Dr. Witgar Weber explained tasks of the Verband Region Stuttgart concerning public transport, especially the S-Bahn. Mr. Nils Himmelmann explained the work he is doing on instruction for the Verband Region Stuttgart, at finding solutions to reduce the problem of a vertical and horizontal interval at the entrance of S-Bahn carriages. As a result of the round table, a profile of requirements was compiled by participants, including preferences for a barrierfree use of the S-Bahn. For the S-Bahn system they demand a partial raise of platforms and where a static raise is not possible there should be a dynamic partial raise. This measure should be combined with an extending step at the entrances of the S-Bahn to solve both horizontal and vertical intervals. Further, the integration of disabled and handicapped people in planning is essential at an early stage. Not only for new projects but also for the modifications of trails or carriages. Therewith, concrete problems can be identified immediately which leads to a reduction of costs in realising requirements for a barrierfree public transport instead of very expensive modifications afterwards.

    Ion mobility spectrometry (IMS) has been used for over 20 years, and IMS coupled to gas chromatography (GC/IMS) has been used for over 10 years. There still is no systematic approach to IMS spectral interpretation such as exists for mass spectrometry and infrared spectrometry. Neural networks, a form of adaptive pattern recognition, were examined as a method of data reduction for IMS and GC/IMS. A wide variety of volatile organics were analyzed using IMS and GC/IMS and submitted to different networks for identification. Several different networks and data preprocessing algorithms were studied. A network was linked to a simple rule-based expert system and analyzed. The expert system was used to filter out false positive identifications made by the network using retention indices. The various network configurations were compared to other pattern recognition techniques, including human experts. The network performance was comparable to human experts, but responded much faster. Preliminary comparison of the network to other pattern recognition showed comparable performance. Linkage of the network output to the rule-based retention index system yielded the best performance.

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.

  2. Ion Mobility Spectrometry (IMS) and Mass Spectrometry

    In a media of finite viscosity, the Coulomb force of external electric field moves ions with some terminal speed. This dynamics is controlled by “mobility” - a property of the interaction potential between ions and media molecules. This fact has been used to separate and characterize gas-phase ions in various modes of ion mobility spectrometry (IMS) developed since 1970. Commercial IMS devices were introduced in 1980-s for field detection of volatile traces such as explosives and chemical warfare agents. Coupling to soft-ionization sources, mass spectrometry (MS), and chromatographic methods in 1990-s had allowed IMS to handle complex samples, enabling new applications in biological and environmental analyses, nanoscience, and other areas. Since 2003, the introduction of commercial systems by major instrument vendors started bringing the IMS/MS capability to broad user community. The other major development of last decade has been the differential IMS or “field asymmetric waveform IMS” (FAIMS) that employs asymmetric time-dependent electric field to sort ions not by mobility itself, but by the difference between its values in strong and weak electric fields. Coupling of FAIMS to conventional IMS and stacking of conventional IMS stages have enabled two-dimensional separations that dramatically expand the power of ion mobility methods.

    Ion mobility spectrometry techniques (IMS and IMS-IMS) combined with collision-induced dissociation (CID) and mass spectrometry (MS) are used to investigate the structures of singly-lithiated carbohydrate isomers. With the exception of some favorable cases, IMS-MS analyses of underivatized carbohydrates reveal that most isobaric precursor ions have similar collision cross sections (ccs). In contrast, ccs values for isomeric fragment ions obtained by IMS-CID-IMS-MS analysis are often different, and thus appear to be useful as a means of distinguishing the isomeric precursors. We report values of ccs (in He) for precursor- and associated-fragment ions for three monosaccharide isomers (glucose, galactose and fructose), ten disaccharide isomers (sucrose, leucrose, palatinose, trehalose, cellobiose, β-gentiobiose, isomaltose, maltose, lactose and melibiose), and three trisaccharide isomers (raffinose, melezitose and maltotriose). These values are discussed as a means of differentiating precursor carbohydrates.

Ausgangspunkt war die These, dass die geographische Entfernung Kolumbiens zu Deutschland und die damit einhergehenden fehlenden Möglichkeiten der Lernenden, ihr im Unterricht erworbenes Wissen zu kontextualisieren, sich erschwerend auf die Entwicklung interkultureller Kompetenzen auswirkt. Mit dem Ziel, diese Schwierigkeit zu kompensieren, wurden zunächst die spezifischen Bedürfnisse der Lernenden ermittelt und verschiedene Lehrbücher hinsichtlich ihrer Angebote auf diese Bedürfnisse evaluiert. Schließlich wird gezeigt, wie die Ergebnisse in die Unterrichtspraxis implementiert wurden.   This article present s the results of an Action Research study carried out between 2010 and 2012 at the Colombian Universidad de los Andes. Its starting point was the hypothesis that the geographical distance between Colombia and Germany makes it more difficult for the students to contextualize the knowledge acquired in class, therefore impeding the development of intercultural competences. In order to compensate for this lack of contextualization the investigators first established the students´ specific needs. Then they evaluated different textbooks with regard to what they are offering to respond to those needs. Finally, the article describes how the findings were implemented in the classroom.

  12. IMS-MS and IMS-IMS investigation of the structure and stability of dimethylamine-sulfuric acid nanoclusters.

    Science.gov (United States)

    Ouyang, Hui; He, Siqin; Larriba-Andaluz, Carlos; Hogan, Christopher J

    2015-03-12

    Recent studies of new particle formation events in the atmosphere suggest that nanoclusters (i.e, the species formed during the early stages of particle growth which are composed of 10(1)-10(3) molecules) may consist of amines and sulfuric acid. The physicochemical properties of sub-10 nm amine-sulfuric acid clusters are hence of interest. In this work, we measure the density, thermostability, and extent of water uptake of <8.5 nm effective diameter dimethylamine-sulfuric (DMAS) nanoclusters in the gas phase, produced via positive electrospray ionization. Specifically, we employ three systems to investigate DMAS properties: ion mobility spectrometry (IMS, with a parallel-plate differential mobility analyzer) is coupled with mass spectrometry to measure masses and collision cross sections for <100 kDa positively charged nanoclusters, two differential mobility analyzers in series (IMS-IMS) are used to examine thermostability, and finally a differential mobility analyzer coupled to an atmospheric pressure drift tube ion mobility spectrometer (also IMS-IMS) is used for water uptake measurements. IMS-MS measurements reveal that dry DMAS nanoclusters have densities of ∼1567 kg/m(3) near 300 K, independent of the ratio of dimethylamine to sulfuric acid originally present in the electrospray solution. IMS-IMS thermostability studies reveal that partial pressures of DMAS nanoclusters are dependent upon the electrospray solution concentration ratio, R = [H2SO4]/[(CH3)2NH]. Extrapolating measurements, we estimate that dry DMAS nanoclusters have surface vapor pressures of order 10(-4) Pa near 300 K, with the surface vapor pressure increasing with increasing values of R through most of the probed concentration range. This suggests that nanocluster surface vapor pressures are substantially enhanced by capillarity effects (the Kelvin effect). Meanwhile, IMS-IMS water uptake measurements show clearly that DMAS nanoclusters uptake water at relative humidities beyond 10% near 300

    The properties of the boron-doped diamond are sensitive to the boron concentration. A semiconducting behaviour occurs at low boron concentration and transport properties are given by a hopping-mechanism. The conductivity increases for higher boron concentration. The Mott metal to insulator transition takes place at a critical boron concentration. In the metallic phase superconductivity is observed. The critical temperatures of the superconducting transition are below 3 K. In this work, the influence of boron to the electronic properties, like conductivity and magneto resistance, was studied in the vicinity of the metal to insulator transition point. The superconducting properties (critical temperature, upper critical field) were studied down to 50 mK and compared to the conventional theory of the electron-phonon coupled superconductors. The properties of polycrystalline RuIn{sub 3} are reported in few publications to be metallic. In this work single crystals of this material were grown and analysed. We observe a semiconducting behaviour with an intrinsic gap of 0.4-0.5 eV. The previously reported metallic behaviour could be interpreted in this work as influence of the elementary indium in the samples. The measurements of the specific heat at low temperatures and LDA band structure calculations confirm the semiconducting properties and the value of the semiconducting gap. (orig.)

  18. Transversal modulation ion mobility spectrometry (IMS) coupled with mass spectrometry (MS): exploring the IMS-IMS-MS possibilities of the instrument.

    Science.gov (United States)

    2015-02-03

    A prototype is introduced based on the transversal modulation ion mobility spectrometry (TMIMS) technique, which provides a continuous output of mobility-selected ions, greatly easing the synchronization between different analyzing stages. In the new architecture, two stages of filtration are used to drastically reduce the background produced by one stage alone. Two-stages TMIMS was coupled with two different atmospheric pressure interface mass spectrometers (MS). The new system enables IMS-IMS-MS analysis and other modes of operation: IMS prefiltration, IMS-IMS, and full transmission mode. It provides a resolving power R > 60 in IMS mode, and R > 40 in each stage of IMS-IMS mode. 2-Propanol vapors were introduced in one of the stages to enhance the mobility variations, and their effect was studied on a set of tetraalkylammonium ions. We found that concentrations as low as 1% (in partial pressure) produce mobility variations as high as 20%, which suggest that IMS-IMS separation using dried N2 (in one stage) and a dopant (in the other stage), could be a very powerful way to enhance the separation capacity of the IMS-IMS prefiltration approach.

    Much progress has been made in plasma wave research as a result of the International Magnetospheric Study (IMS) in all areas from ground-based studies to multiple-satellite observations. Studies in all the areas have contributed to better understanding of the propagation and generation of magnetospheric plasma waves and the impact the waves have on other magnetospheric phenomena. Plasma wave measurements have been used as both local and remote sensing determinations of plasma parameters. The role of plasma waves at the various magnetospheric boundaries has been extensively studied using the IMS sources. Plamsa wave observations during the IMS have tested many existing theories and led to the foundation of many new theories. Several suggestions for future directions of plamsa wave research are offered.

    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

  5. IMS Seismic and Infrasound Stations Instrumental Challenges

    2016-12-01

    The IMS seismic network is a set of monitoring facilities including 50 primary stations and 120 auxiliary stations. Besides the difference in the mode of data transmission to the IDC, technical specifications for seismographic equipment to be installed at both types of stations are essentially the same. The IMS infrasound network comprises 60 facilities with the requirement of continuous data transmission to IDC. The objective of this presentation is to report instrumental challenges associated with both seismic and infrasound technologies. In context of specifications for IMS seismic stations it was stressed that verification seismology is concerned with searching of reliable methods of signal detections at high frequencies. In the meantime MS/mb screening criteria between earthquakes and explosions relies on reliable detection of surface waves. The IMS seismic requirements for instrumental noise and operational range of data logger are defined as certain dB level below minimum background within the required frequency band from 0.02 to 16Hz. The type of sensors response is requested to be flat either in velocity or acceleration. The compliance with IMS specifications may thus introduce a challenging task when low-noise conditions have been recorded at the site. It means that as a station noise PSD approaches the NLNM it requires a high sensitive sensor to be connected to a quiet digitizer which may cause a quick system clip and waste of the available dynamic range. The experience has shown that hybrid frequency response of seismic sensors where combination of flat to velocity and flat to acceleration portions of the sensor frequency response may provide an optimal solution for utilization of the dynamic range and low digitizer noise floor. Vast efforts are also being undertaken and results achieved in the infrasound technology to standardize and optimize the response of the Wind-Noise Reduction System within the IMS infrasound passband from 0.02-4Hz and to deploy

    Findings and Strategic Implications. To complement earlier theoretical proposition on IM, the findings indicate that there are several empirical aspects such as “costs, people and concept” which hinder successful implementation of IM. This study proposes several strategic HR recommendations to reduce the “implementation gap” in IM such as to conduct continuous staff training on IM knowledge on regular time intervals, to reduce excessive work load and pressure and engaging staff members in continuous personal development sessions. In addition, the findings reveal that IM training should be given priority to solve “people-oriented” issues.

The IMS is based on session initiation protocol (SIP to establish, modify, and terminate the sessions. It provides a clean separation between services, signaling, and media with the potential to enable control and management of services over multiple transport technologies. In the scope of fixed-mobile convergence, this paper is dedicated to presenting a review of how cable networks can be integrated into IMS technology to achieve 3G-cable horizontal convergence. Cable networks, as one of the major fixed broadband access technologies with PacketCable architecture, are able to provide broadband internet access and VoIP in addition to cable TV. In this article, we review the evolution in PacketCable architecture to take up IMS. In this way, we consider the standardization and research activities to address this integration. We review some important challenges such as SIP protocol compatibility, defining unique user profile, required enhancement in authentication process, QoS and charging system.

    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.

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

    2003-07-01

    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 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..

    This work focuses on direct matrix assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS) detection of intraperitoneally (IP) injected dipeptide ZP1609 in mouse brain tissue. Direct analysis of drug detection in intact tissue sections provides distribution information that can provide information to impact drug development. MALDI IMS capabilities of uncovering drug transport across the blood-brain barrier are demonstrated. Successful peptide detection using MALDI IMS was achieved using a MALDI TOF TOF system. Upon optimization of sample preparation procedures for dipeptide ZP1609, an additional tissue acidification procedure was found to greatly enhance signal detection. The imaging data acquired was able to determine successful transport of ZP1609 across the blood-brain barrier. Data obtained from MALDI IMS can help shape our understanding of biological functions, disease progression, and effects of drug delivery. Direct detection of ZP1609 throughout the brain tissue sections were observed from MALDI MS images. However, in cases where there was induction of stroke, a peak of lower signal intensity was also detected in the target m/z region. Although distinct differences in signal intensity can be seen between control and experimental groups, fragments and adducts of ZP1609 were investigated using MALDI IMS to verify detection of the target analyte. Overall, the data reveals successful penetration of ZP1609 across the blood-brain barrier. The benefits of tissue acidification in the enhancement of detection sensitivity for low abundance peptides were demonstrated. MALDI IMS has shown to be a useful technique in the direct detection of drugs within intact brain tissue sections. This article is protected by copyright. All rights reserved.

    The Investment Model (IM; Rusbult, 1980, 1983) has been widely used to study the development and maintenance of romantic relationships. Its components--satisfaction, quality of alternatives, investment size and commitment--are operationalized in the Investment Model Scale (IMS; Rusbult, Martz, & Agnew, 1998). Given its importance for personal relationships literature, this article presents the adaptation and validation of the IMS to Portugal, and the development and validation of a shorter version, the IMS-S. A confirmatory factor analysis replicates the IMS's original four factors structure. A similar structure was found for the IMS-S. For both versions, results show the instruments to have validity and good reliability. Results are discussed considering the scales' importance for studying romantic relationships.

Eines der Fährnisse ist das Verhältnis zwischen bildlichen und schriftlichen Anteilen: Nicht selten wird der künstlerische Anteil zur Illustration der dominierenden Schrift. Eine Neupositionierung des Bildes im Buch ist nun der amerikanischen Künstlerin Roni Horn gelungen. Mehr als „sujet“ ihres Buches, ist die französische Philosophin Hélène Cixous gleichsam instruierende „Stimme“, die im Bild aufscheint. Horn hat dadurch zugleich – einmal mehr – das Phantasma unmittelbarer Abbildhaftigkeit des Fotos dekonstruiert und der philosophischen Position Cixous‘ durch das Bild eine Dimension hinzugefügt.Books created through a combined effort between artists and scholars occur seldom and are not always successful. A particular imbalance is found in the relationship between image and text: often the visual components serve merely to illustrate the more dominant text. The American artist Roni Horn has finally repositioned the importance of images in books. The voice of French philosopher Hélène Cixous is not merely the “sujet” of Horn’s book, but her instructive voice appears simultaneously in “image.” Horn thus both deconstructs the chimera of the photo’s ability to immediately visually depict the real and also adds a new dimension to Cixous’ philosophic position with her images.

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.

    Measurements and analysis of more than 100 samples of tap-water, originated from different countries of the Federal Republik of Germany, have been performed by means of the standardized TEM-procedure (ISO). The results have shown that the drinking water is contaminated with fine fibers, with chrysotile and amphibole asbestos. The majority of investigated samples contained less than 10{sup 6} fibers/liter, and the fibers were thin and shorter than 5 {mu}m. Nevertheless, in some tap-water samples the asbestos fiber concentrations were higher than 10{sup 6} fibers/liter and/or the content of long fibers (longer than 5 {mu}m) was relatively high. It is recommended tapwater with asbestos fiber concentrations over 10{sup 6} fibers/liter and/or with greater content of long fibers should not be used for cooking or drinking unless filtered.

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.

    The International Monitoring System (IMS) developed by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) is a global system of monitoring stations, using four complementary technologies: seismic, hydroacoustic, infrasound and radionuclide. The radionuclide network comprises 80 stations, out of which 40 are to be equipped with noble gas systems. The aim of radionuclide stations is a global monitoring of radioactive aerosols, radioactive noble gases and atmospheric transport modelling (ATM). To investigate the transport of radionuclide emissions, the Provisional Technical Secretariat (PTS) operates an Atmospheric Transport Modelling (ATM) system based on the Lagrangian Particle Dispersion Model FLEXPART. The air mass trajectory provides a "link" between a radionuclide release and a detection confirmed by radionuclide measurements. The aim of this study is to demonstrate the RN analysis and the application of ATM to investigate the episodes of elevated levels of radioxenon observed by IMS stations after the sixth nuclear test, announced by the Democratic People's Republic of Korea (DPRK) at the Punggye-ri Nuclear Test Site on 3 September 2017. A comparison to the previous tests will be presented.

    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.)

    Full Text Available Sprachwissenschaftliche Untersuchungen lassen darauf schließen, dass die historischen Dialekte der alten Hellenen erst auf griechischem Boden um und nach 1000 v. Chr. entstanden sind. Bei den frühen Zuwanderern kann es sich nur um kleinere Verbände gehandelt haben, so daß zweifelllos keine großen „Stämme“ nach Griechenland vorgedrungen sind, wie man in der älteren Forschung angenommen hat. In Griechenland haben die Zuwanderer die Suffixe -ss und -nth oder -nd nicht erst kennengelernt, sondern zumindest zum Teil schon mitgebracht und vermutlich im 3. Jahrtausend v. Chr. die allmähliche Entwicklung des späteren Griechischen eingeleitet. Impulse für die Entwicklung der materiellen Kultur gingen um 1700 v. Chr. von Kreta aus und beeinflussten in starkem Maße die mykenische Zeit mit ihren Palastsystemen, deren Zusammenbruch um 1200 v. Chr. aber nicht schon zum Ende der mykenischen Kultur führte, wenn auch die Linear B-Schrift nicht mehr benutzt wurde und die Infrastrukturen der Machtzentren zusammenbrachen.

    Mach probe measurements of bias-induced ion flows were made in the Interchangeable Module Stellarator (IMS) as a function of neutral pressure and viscosity (which increases with minor radius) and compared to a fluid theory model. Using a probe model for an unmagnetized plasma, the poloidal flow speed measured with a Mach probe agrees with that calculated from momentum balance to within 15%. The dependencies of the measured ion flow magnitudes and decay rates on neutral pressure and viscosity as predicted by the theory are qualitatively observed in the experimental measurements, clearly demonstrating the effects of both ion-neutral collisions and viscosity in the damping of the bias-induced flows. However, the measured flow direction is nearly poloidal, while the theory predicts a predominantly Pfirsch-Schlueter-like toroidal flow. Also the two-dimensional variation at a constant toroidal angle of the parallel electron current was measured in an unbiased plasma. The measured profiles demonstrate the dependence of the current on both the radial pressure gradient and the cosine of the poloidal angle, as predicted by theory. 11 refs., 5 figs.

    Central nervous system (CNS) tumors are the most common solid neoplasms in childhood and the second most common malignancies after leukemia in the pediatric age group. Supratentorial tumors are more common in children younger than 2 years old and in adolescents, whereas in patients between 2 and 12 years of age brain tumors originating in the posterior fossa dominate. This implies a relationship between the type of tumor, its location and the age of the patient, which has to be considered in differential diagnoses. Medulloblastoma represents the most common malignant brain tumor in childhood. In the posterior fossa medulloblastomas are approximately as frequent as astrocytomas. Supratentorial astrocytomas are by far the main tumor type. In this report some typical CNS neoplasms in children are discussed and their neuroradiological features are demonstrated. (orig.) [German] Hirntumoren sind die haeufigsten soliden Tumoren des Kindesalters und repraesentieren nach den Leukaemien die zweithaeufigsten malignen Erkrankungen bei Kindern. Waehrend bei Kleinkindern und Adoleszenten supratentorielle Hirntumoren ueberwiegen, ist bei Patienten zwischen 2 und 12 Jahren haeufiger die hintere Schaedelgrube Ursprungsort dieser Malignome. Daraus geht hervor, dass gewisse Tumortypen eine gewisse Alterspraedilektion aufweisen, was neben der radiologischen Morphologie der Raumforderung fuer differenzialdiagnostische Ueberlegungen ueberaus hilfreich sein kann. Das Medulloblastom ist das haeufigste ZNS-Malignom des Kindesalters und repraesentiert zusammen mit zerebellaeren Astrozytomen auch den haeufigsten Tumortyp der hinteren Schaedelgrube. Supratentoriell stehen die Astrozytome ganz im Vordergrund.

    Research into environmental factors and how they affect the health of children needs to address a number of questions: Does the environment play any part in this at all? What are the affecting environmental factors? What is the scope of specific environmental factors relative to an induction or an enhancement of a disease? The search for and identification of allergens has priority relative to allergic developments in children. The author describes major allergen sources, the pathogenesis of allergies, the analysis of allergens and a study conducted by several pediatric clinics on the development of allergies in infants and young children, while focussing on risk factor of house-dust mites and options to reduce the exposure to mite-associated allergens. (Uhe) [Deutsch] Bei der Erforschung von Umweltfaktoren und ihrem Einfluss auf die Gesundheit von Kindern interessieren mehrere Fragen: spielt die Umwelt ueberhaupt ein Rolle?

Fuef die Allergieentwicklung bei Kindern stehen die Allergene an erster Stelle. Neben der Beschreibung der wichtigsten Allergiequellen und der Entstehung von Allergien und Analytik von Allergenen wird ausfuehrlich eine Studie verschiedener Kinderkliniken zur Allergieentwicklung im Kindesalter beschrieben. Dabei wird vor allem auf den Risikofaktor Hausstaubmilbe und die Moeglichkeiten der Reduzierung der Milbenallergenbelastung eingegangen. (Uhe)

Mit der Arbeit soll nachgewiesen werden, dass sich die Motivation der türkischen Studierenden zum Deutschlernen durch die direkte Begegnung mit deutschen Lehramts-Praktikanten positiv beeinflusst werden kann. In diesem Zusammenhang wurde der Beitrag deutscher Lehramts-Praktikanten auf die Motivation der türkischen DaF-Studierenden ausgehend von den Studentenmeinungen untersucht. Generell fällt es türkischen Studierenden schwer, sich in der Fremdsprache zu äußern, zu sprechen oder zu schreiben, sobald man über Standardsituationen des Alltagskommunikation hinausgeht. Ein Grund dafür ist das Fehlen von Sprachkompetenz, aber auch von Erfahrungen bei konkreten Sprechanlässen und Sprechsituationen. Der Einsatz von Lehramts-Praktikanten, die im Rahmen des Erasmus-Programs im universitären Unterricht assistieren, soll diesem Mangel entgegen wirken. Die Studierenden sollen dabei unterstüzt werden, sich in der Fremdsprache zu äußern. Mit vorliegender Untersuchung wird der Frage nachgegangen, ob der Einsatz von Lehramts-Praktikanten aus Deutschland im universitären DaF-Unterricht in der Türkei das Interesse zum Deutschlernen fördert.

    The Provisional Technical Secretariat (PTS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBTO) has a continuous interest in enhancing its capability in acoustic source detection, localization and characterization. The infrasound component of the International Monitoring System (IMS) constitutes the only worldwide ground-based infrasound network. It consists of sixty stations, among which forty-eight are already certified and continuously transmit data to the International Data Centre (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. The characteristics of infrasonic waves are computed in near real-time by IDC automatic detection software and are used as an input to IDC source categorization and localization algorithms. The PTS is continuously working towards the completion and sustainment of the IMS infrasound network. The objective of this presentation is to review the main activities performed in the IMS infrasound network over the last five years. This includes construction, installation, certification, major upgrade and revalidation activities. Major technology development projects to improve the reliability and robustness of IMS infrasound stations as well as their compliance with IMS Operational Manual requirements will also be presented. This includes advances in array geometry, wind noise reduction, system calibration, meteorological data as well as power and communication infrastructures. Finally the impact of all these changes on the overall detection capability of the IMS infrasound network will be highlighted.

    Ion mobility spectrometry (IMS) is a fast and sensitive analytical method which operates at the atmospheric pressure. To enhance the capability of IMS for the analysis of mixtures, it is often used with preseparation techniques, such as GC or HPLC. Here, we report for the first time the coupling of the thin-layer chromatography and IMS. A variety of coupling schemes were tried that included direct electrospray from the TLC strip tip, indirect electrospray from a needle connected to the TLC strip, introducing the moving solvent into the injection port, and, the simplest way, offline introduction of scratched or cut pieces of strips into the IMS injection port. In this study a special solvent tank was designed and the TLC strip was mounted horizontally where the solvent would flow down. A very small funnel right below the TLC tip collected the solvent and transferred it to a needle via a capillary tubing. Using the TLC-ESI-IMS technique, acceptable separations were achieved for two component mixtures of morphine-papaverine and acridine-papaverine. A special injection port was designed to host the pieces cut off the TLC. The method was successfully used to identify each spot on the TLC by IMS in a few seconds.

    The Federal Environment Agency is therefore proposing a multitude of measures which have the potential to significantly reduce the CO{sub 2} emissions caused by transport and to thus achieve the German Federal Government's climate protection objectives. The measures target both freight and passenger transport and cover all transport modes (heavy goods vehicles, passenger cars, inland waterways, rail, air, pedestrians and bicycles). The Federal Environment Agency suggests a range of complementary measures in the following fields: - Traffic avoidance: Influencing / reducing transport demand and shortening distances. - Modal shift: Shifting transport to more environmentally friendly modes. - Optimising transport: Better utilisation of existing transport capacities. - Economic measures and - direct emission reduction on vehicles. In line with this, the measures and instruments proposed focus on the following areas: - Traffic-reducing through town planning and transport planning - Promoting environmentally friendly transport modes - Economic measures - Measures to improve vehicle and fleet efficiency - Consumer information and driving behaviour in road traffic The table below provides an overview of the measures and their reduction potential for the years 2020 and 2030. The calculated CO{sub 2} savings result from the divergence from the trend scenario which was calculated using the ''TREMOD'' model and is based on measures for the transport sector which have already been adopted. The potentials from the various individual measures proposed by the Federal Environment Agency cannot simply be added up, since the measures may be mutually reinforcing or reducing each others effect. For instance, if fewer heavy goods vehicles are on the road because of a switch to rail, this reduces the absolute reduction that could be achieved by the HGV fleet through e.g. the use of low-friction oils and low-rolling-resistance tyres.

    2014-09-01

    The IMS CORE Diabetes Model (CDM) is a widely published and validated simulation model applied in both type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) analyses. Validation to external studies is an important part of demonstrating model credibility. Because the CDM is widely used to estimate long-term clinical outcomes in diabetes patients, the objective of this analysis was to validate the CDM to contemporary outcomes studies, including those with long-term follow-up periods. A total of 112 validation simulations were performed, stratified by study follow-up duration. For long-term results (≥15-year follow-up), simulation cohorts representing baseline Diabetes Control and Complications Trial (DCCT) and United Kingdom Prospective Diabetes Study (UKPDS) cohorts were generated and intensive and conventional treatment arms were defined in the CDM. Predicted versus observed macrovascular and microvascular complications and all-cause mortality were assessed using the coefficient of determination (R(2)) goodness-of-fit measure. Across all validation studies, the CDM simulations produced an R(2) statistic of 0.90. For validation studies with a follow-up duration of less than 15 years, R(2) values of 0.90 and 0.88 were achieved for T1DM and T2DM respectively. In T1DM, validating against 30-year outcomes data (DCCT) resulted in an R(2) of 0.72. In T2DM, validating against 20-year outcomes data (UKPDS) resulted in an R(2) of 0.92. This analysis supports the CDM as a credible tool for predicting the absolute number of clinical events in DCCT- and UKPDS-like populations. With increasing incidence of diabetes worldwide, the CDM is particularly important for health care decision makers, for whom the robust evaluation of health care policies is essential.

  2. Grundlegende Steuerungsverfahren im heterogenen Logistiknetz mit Kanban

    In vielen Unternehmen werden heterogene (verschiedene) Steuerungen in einem abgestimmten Konzept kombiniert. Je nach Anwendungsfall und Rahmenbedingungen werden Kombinationen allgemein bekannter Steuerungen oder Steuerungsvarianten gemischt eingesetzt, um eine optimale Steuerung für unterschiedliche Fälle zu erreichen. Hierbei stehen neben den bekannten und weit verbreiteten Methoden, wie Material Requirements Planning (MRP) oder Kanban, auch weniger bekannte oder neue Methoden zur Auswahl, wie die Produktionssteuerung mit dezentraler, bestandsorientierter Fertigungsregelung (DBF). Kanban ist ein simples und effizientes Steuerungskonzept, das in der klassischen Form für spezifische einfache Anwendungsfälle umsetzbar ist. Hochentwickelte Steuerungsalgorithmen können helfen, komplexe Abläufe optimal abzubilden. Mit einer grundlegenden Vereinfachung der Abläufe kann allerdings in vielen Fällen ein wesentlich stärkerer und umfassender Verbesserungseffekt erzielt werden. Die wesentliche Fragestellung sollte folglich lauten: Warum ist der Ablauf nicht mit einer einfachen Steuerung wie Kanban abzubilden? Um die Vorteile des Konzepts auch in untypischen Bereichen anwenden zu können, sind jedoch verschiedene Varianten oder Kanban-ähnliche Steuerungsmethoden entstanden. Darüber hinaus sind in der Praxis hybride Steuerungen im Einsatz, welche so kombiniert werden, dass die Zusammensetzung anspruchsvolle Eigenschaftsbilder noch exakt abbildet. In der Praxis basieren die Steuerungsentscheidungen nur zu einem kleinen Teil auf den eigentlichen Steuerungsalgorithmen, wie sie uns das MRP-System zur Verfügung stellt. Moderne Steuerungswelten" schließen alle relevanten Informationsquellen in eine heterogene Entscheidungsmatrix mit ein. Letztlich zählt nicht, ob die Entscheidung auf den Informationen aus dem MRP-System oder auf Softfacts basierend getroffen wurde, sondern nur, ob die Entscheidung erfolgreich war.

  3. Ion mobility spectrometer / mass spectrometer (IMS-MS).

    The use of Ion Mobility Spectrometry (IMS) in the Detection of Contraband Sandia researchers use ion mobility spectrometers for trace chemical detection and analysis in a variety of projects and applications. Products developed in recent years based on IMS-technology include explosives detection personnel portals, the Material Area Access (MAA) checkpoint of the future, an explosives detection vehicle portal, hand-held detection systems such as the Hound and Hound II (all 6400), micro-IMS sensors (1700), ordnance detection (2500), and Fourier Transform IMS technology (8700). The emphasis to date has been on explosives detection, but the detection of chemical agents has also been pursued (8100 and 6400). Combining Ion Mobility Spectrometry (IMS) with Mass Spectrometry (MS) is described. The IMS-MS combination overcomes several limitations present in simple IMS systems. Ion mobility alone is insufficient to identify an unknown chemical agent. Collision cross section, upon which mobility is based, is not sufficiently unique or predictable a priori to be able to make a confident peak assignment unless the compounds present are already identified. Molecular mass, on the other hand, is much more readily interpreted and related to compounds. For a given compound, the molecular mass can be determined using a pocket calculator (or in one's head) while a reasonable value of the cross-section might require hours of computation time. Thus a mass spectrum provides chemical specificity and identity not accessible in the mobility spectrum alone. In addition, several advanced mass spectrometric methods, such as tandem MS, have been extensively developed for the purpose of molecular identification. With an appropriate mass spectrometer connected to an ion mobility spectrometer, these advanced identification methods become available, providing greater characterization capability.

  4. Instrumentale Spielformeln und Vokale Verzierungen im 16.Jahrhundert

    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.

  5. 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.

  7. Hot plasma and energetic particles in the earth's outer magnetosphere: new understandings during the IMS

    Energy Technology Data Exchange (ETDEWEB)

    Baker, D.N.; Fritz, T.A.

    1984-01-01

    In this paper we review the major accomplishments made during the IMS period in clarifying magnetospheric particle variations in the region from roughly geostationary orbit altitudes into the deep magnetotail. We divide our review into three topic areas: (1) acceleration processes; (2) transport processes; and (3) loss processes. Many of the changes in hot plasmas and energetic particle populations are often found to be related intimately to geomagnetic storm and magnetospheric substorm effects and, therefore, substantial emphasis is given to these aspects of particle variations in this review. The IMS data, taken as a body, allow a reasonably unified view as one traces magnetospheric particles from their acceleration source through the plasma sheet and outer trapping regions and, finally, to their loss via ionospheric precipitation and ring current formation processes. It is this underlying, unifying theme which is pursued here. 52 references, 19 figures.

  8. Status of IMS workshops - CDAW 1: December 1977 events

    Rostoker, G.

    In connection with the acquisition of a very comprehensive data set as a result of the International Magnetospheric Study (IMS), investigations were being conducted concerning the most appropriate approaches for an analysis of the data by IMS researchers, taking into account procedures which would ensure an exposure of the results of the IMS to the largest possible audience in the least amount of time. Two formats considered for interaction among IMS researchers include the 'Working Conference' and the prototype of the Coordinated Data Analysis Workshop (CDAW). It was recognized that the large amount of data involved demanded the use of a large computer data bank if any progress was to be made in a time-limited workshop. It was decided to discuss the nature of the data acquired over the December 1977 interval at a Working Conference in June 1978. Some time after the Working Conference it was announced that CDAW 1.0 would be held at the Satellite Situation Center in December 1978. It is pointed out that the IMS community has profited greatly from the experience of CDAW 1.

  9. Handover Based IMS Registration Scheme for Next Generation Mobile Networks

    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.

    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.

    1997-10-01

    The effective control of pollutants in ambient air requires their fast in situ identification and concentration determination of chemical compounds in the range of micrograms per m{sup 3}. There are attempts to use conventional analytical techniques as portable GC and GC-MS. These systems are relatively expensive. A new supersensitive ion Mobility Sensor (IMS) was developed and checked by IUT Ltd, which meets the new demands. The use of tritium sources is an advantage in comparison with other IMS being equipped by nickel-63, the application of which is rather critical in respect of the radiation protection. On the other hand an integrated separation column allows to reduce interferences by matrix effects. The technical parameters of the IUT GC- IMS and some of its most important applications are briefly presented 6 refs., 1 tab., 5 figs.

  15. Assessing the Peak Capacity of IMS-IMS Separations of Tryptic Peptide Ions in 300 K He

    2011-01-01

    Two-dimensional ion mobility spectrometry (IMS-IMS) coupled with mass spectrometry is examined as a means of separating mixtures of tryptic peptides (from myoglobin and hemoglobin). In this study we utilize two distinct drift regions that are identical in that each contains He buffer gas at 300 K. The two-dimensional advantage is realized by changing the structures of the ions. As ions arrive at the end of the first drift region, those of a specified mobility are selected, exposed to energizing collisions, and then introduced into a second drift region. Upon collisional activation some ions undergo structural transitions, leading to substantial changes in their mobilities; others undergo only slight (or no) mobility changes. Examination of peak positions and shapes for peptides that are separated in the first IMS dimension indicates experimental peak capacities ranging from ~60 to 80; the peak shapes and range of changes in mobility that are observed in the second drift region (after activation) indicates a capacity enhancement ranging from a factor of ~7 to 17. Thus, experimental (and theoretical) evaluation of the peak capacity of IMS-IMS operated in this fashion indicates that capacities of ~480 to 1360 are accessible for peptides. Molecular modeling techniques are used to simulate the range of structural changes that would be expected for tryptic peptide ions and are consistent with the experimental shifts that are observed.

    Preoperative imatinib mesylate (IM) treatment has not yet been standardized. Here, we aim to further explore such therapy on patients with gastrointestinal stromal tumors (GIST) retrospectively. Patients experiencing preoperative IM were identified from January 2009 to February 2015. A total of 28 GIST patients were identified. The patients received preoperative IM treatment for a median length of 13.5 months, ranging from 5 to 37 months. PR and SD were observed in 24 (85.7%) and 4 (15.3%) patients, respectively. The tumor shrinkage occurred predominantly within 6 to 12 months, and slight tumor shrinkage could be observed after 12 months in certain patients. Nineteen patients (67.9%) received surgery, and R0 resection was acquired in 18 (94.7%) patients. The initial mean maximum diameter was 10.5 (5.2 to 19.0) cm and decreased to 5.9 (2.7 to 19.0) cm after preoperative treatment with a median length of 12 (ranging from 5 to 36) months (P < 0.001) in patients receiving operations. Three in 7 cases of rectum GIST underwent abdominoperineal resection, and four others adopted sphincter-sparing resection. Partial gastrectomy was performed in four patients. IM prior to surgery can effectively prevent tumor rupture and facilitate surgery with low surgical morbidity for GIST patients. Tumor shrinkage following IM occurred predominantly within 6 to 12 months, and slight tumor shrinkage could be observed after 12 months in certain patients. In selected patients, prolonged exposure to IM is seemingly advisable under close radiological surveillance.

    The results of experimental studies of fluctuations and transport in ECH plasmas in the ATF torsatron and the IMS stellarator are presented. In ATF, a variety of diagnostics have been used to measure turbulence amplitudes and spectral characteristics throughout the plasma. In the plasma core, density fluctuations with characteristics like those expected for drift waves (possibly connected with trapped electron effects) are seen. In the gradient region, the density fluctuation levels are consistent with those expected for resistive interchange turbulence. In the edge, fluctuations appear to be correlated with density gradients, and the fluctuation-induced particle flux and global particle confinement can be influenced by positive limiter biasing. In IMS, whose parameters model those in the edge of larger devices, two-dimensional (2-D) probe measurements show substantial poloidal variations in the fluctuation-induced particle flux that are most pronounced at the plasma edge; as in ATF, the particle flux can be reduced by positive limiter biasing. The 2-D probe measurements also show good agreement between the plasma poloidal flow velocities determined from the Reynolds stress and force balance.

En este análisis, se distingue el uso del término “pastor” como ocupación de otros usos del término transferidos a la divinidad, a los reyes y gobernantes, así como también se distingue del uso Mesías-Pastor de las funciones pastorales del liderazgo cristiano primitivo. El trabajo invita a imaginar a Dios con otras imágenes más relevantes para la vida y cultura latinoamericana, tales como: Dios-Acompañante, Dios-Multiculturalizador/a, Dios-Pacificador/a y Dios-Madre.

  11. Static corrections for enhanced signal detection at IMS seismic arrays

    Science.gov (United States)

    Wilkins, Neil; Wookey, James; Selby, Neil

    2016-04-01

    Seismic monitoring forms an important part of the International Monitoring System (IMS) for verifying the Comprehensive nuclear Test Ban Treaty (CTBT). Analysis of seismic data can be used to discriminate between nuclear explosions and the tens of thousands of natural earthquakes of similar magnitude that occur every year. This is known as "forensic seismology", and techniques include measuring the P-to-S wave amplitude ratio, the body-to-surface wave magnitude ratio (mb/Ms), and source depth. Measurement of these seismic discriminants requires very high signal-to-noise ratio (SNR) data, and this has led to the development and deployment of seismic arrays as part of the IMS. Array processing methodologies such as stacking can be used, but optimum SNR improvement needs an accurate estimate of the arrival time of the particular seismic phase. To enhance the imaging capability of IMS arrays, we aim to develop site-specific static corrections to the arrival time as a function of frequency, slowness and backazimuth. Here, we present initial results for the IMS TORD array in Niger. Vespagrams are calculated for various events using the F-statistic to clearly identify seismic phases and measure their arrival times. Observed arrival times are compared with those predicted by 1D and 3D velocity models, and residuals are calculated for a range of backazimuths and slownesses. Finally, we demonstrate the improvement in signal fidelity provided by these corrections.

    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.

    Full Text Available Dem Zusammenhang von ausländischen Direktinvestionen (Foreign Direct Investment, FDI und Technologietransfer wird sowohl in der Forschung als auch in der politischen Analyse große Bedeutung zugeschrieben. Zahlreiche Veröffentlichungen belegen, dass FDI den Transfer von und/oder den Zugang zu Technologien erleichtert. Allerdings gibt es zu wenige empirische Studien, die diesen Zusammenhang in Bezug auf die Wirtschaft afrikanischer Staaten untersuchen. Der Autor will diese Lücke zu einem kleinen Teil schließen, indem er die Bedeutung des Technologietransfers durch den Zufluss von FDI im Energiesektor Angolas ermittelt. Seine Analyse basiert auf qualitativer Forschung in Angola im Jahr 2014. Er zeigt auf, dass sich die Erzeugung von Energie(trägern und die Verteilungsinfrastruktur - maschinelle Ausrüstung und Qualifizierung - durch den Zufluss von FDI erheblich entwickeln konnte. Allerdings gebe es keinen Beleg dafür, dass dieser Zufluss die endogenen wissenschaftlichen und technologischen Forschungspotenziale im angolanischen Energiesektor gefördert hat. Der Autor empfiehlt politische Maßnahmen zur Förderung dieser Fähigkeiten, insbesondere im Bereich der Produktion.

    Atmospheric CO2 is a critical forcing for the Earth's climate, and knowledge of its distribution and variations influences predictions of the Earth's future climate. Accurate observations of atmospheric CO2 are also crucial to improving our understanding of CO2 sources, sinks and transports. To meet these science needs, NASA is developing technologies for the Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) space mission, which is aimed at global CO2 observations. Meanwhile an airborne investigation of atmospheric CO2 distributions as part of the NASA Suborbital Atmospheric Carbon and Transport â€" America (ACT-America) mission will be conducted with lidar and in situ instrumentation over the central and eastern United States during all four seasons and under a wide range of meteorological conditions. In preparing for the ASCENDS mission, NASA Langley Research Center and Exelis Inc./Harris Corp. have jointly developed and demonstrated the capability of atmospheric CO2 column measurements with an intensity-modulated continuous-wave (IM-CW) lidar. Since 2005, a total of 14 flight campaigns have been conducted. A measurement precision of approx.0.3 ppmv for a 10-s average over desert and vegetated surfaces has been achieved, and the lidar CO2 measurements also agree well with in-situ observations. Significant atmospheric CO2 variations on various spatiotemporal scales have been observed during these campaigns. For example, around 10-ppm CO2 changes were found within free troposphere in a region of about 200A-300 sq km over Iowa during a summer 2014 flight. Results from recent flight campaigns are presented in this paper. The ability to achieve the science objectives of the ASCENDS mission with an IM-CW lidar is also discussed in this paper, along with the plans for the ACT-America aircraft investigation that begins in the winter of 2016.

    Parrot, Delphine; Papazian, Stefano; Foil, Daniel; Tasdemir, Deniz

    2018-01-31

    Imaging mass spectrometry (IMS) has recently established itself in the field of "spatial metabolomics." Merging the sensitivity and fast screening of high-throughput mass spectrometry with spatial and temporal chemical information, IMS visualizes the production, location, and distribution of metabolites in intact biological models. Since metabolite profiling and morphological features are combined in single images, IMS offers an unmatched chemical detail on complex biological and microbiological systems. Thus, IMS-type "spatial metabolomics" emerges as a powerful and complementary approach to genomics, transcriptomics, and classical metabolomics studies. In this review, we summarize the current state-of-the-art IMS methods with a strong focus on desorption electrospray ionization (DESI)-IMS. DESI-IMS utilizes the original principle of electrospray ionization, but in this case solvent droplets are rastered and desorbed directly on the sample surface. The rapid and minimally destructive DESI-IMS chemical screening is achieved at ambient conditions and enables the accurate view of molecules in tissues at the µm-scale resolution. DESI-IMS analysis does not require complex sample preparation and allows repeated measurements on samples from different biological sources, including microorganisms, plants, and animals. Thanks to its easy workflow and versatility, DESI-IMS has successfully been applied to many different research fields, such as clinical analysis, cancer research, environmental sciences, microbiology, chemical ecology, and drug discovery. Herein we discuss the present applications of DESI-IMS in natural product research. Georg Thieme Verlag KG Stuttgart · New York.

    2012-03-01

    Multiyear continuous infrasound monitoring with the global International Monitoring System (IMS) demonstrates that microbaroms, generated by nonlinear interaction of opposing oceanic surface waves, are globally observed at equatorial, middle, and high latitudes. Direction of arrival of microbarom signals are systematically estimated at all IMS infrasound stations. Using a cross-bearing method, we perform a monthly localization of worldwide microbarom sources. At most stations, microbarom detections show clear seasonal trends, driven by stratospheric wind reversals and source effects. Five-year averaging of the detections provides global and statistical observations of seasonal source variations. Our microbarom source locations represent a first attempt to infer ocean swell characteristics from global and long-term measurements. We show that the monthly averaged source locations exhibit clear seasonal switching between the northern and southern hemispheres. Such an approach can help with evaluating the network detection capability, and provides new insights into quantitative relationships between infrasonic observables, atmospheric specifications, and ocean-atmosphere interactions.

    Polleres, Axel; Mochol, Malgorzata

    Im vorliegenden Beitrag diskutieren wir Rahmenbedingungen zur Kombination, Wiederverwendung und Erweiterung bestehender RDFVokabulare im Social Semantic Web. Hierbei konzentrieren wir uns auf das Anwendungsszenario des Auffindens und Bewerbens von Experten im Web oder Intranet. Wir präsentieren, wie RDF-Vokabulare einerseits und de facto Standardformate andererseits, die von täglich verwendeten Applikationen benutzt werden (z. B. vCard, iCal oder Dublin Core), kombiniert werden können, um konkrete Anwendungsfälle der Expertensuche und zum Management von Expertise zu lösen. Unser Fokus liegt darauf aufzuzeigen, dass für praktische Anwendungsszenarien nicht notwendigerweise neue Ontologien entwickelt werden müssen, sondern der Schlüssel vielmehr in der Integration von bestehenden, weit verbreiteten und sich ergänzenden Formaten zu einem kohärenten Netzwerk von Ontologien liegt. Dieser Ansatz garantiert sowohl direkte Anwendbarkeit von als auch niedrige Einstiegsbarrieren in Semantic Web-Technologien sowie einfache Integrierbarkeit in bestehende Applikationen. Die im Web verfügbaren und verwendeten RDFFormate decken zwar einen großen Bereich der Aspekte zur Beschreibung von Personen und Expertisen ab, zeigen aber auch signifikante Überlappungen. Bisher gibt es wenig systematische Ansätze, um diese Vokabulare zu verbinden, sei es in Form von allgemeingültigen Praktiken, die definieren, wann welches Format zu benutzen ist, oder in Form von Regeln, die Überlappungen zwischen einzelnen Formaten formalisieren. Der vorliegende Artikel analysiert, wie bestehende Formate zur Beschreibung von Personen, Organisationen und deren Expertise kombiniert und, wo nötig, erweitert werden können. Darüber hinaus diskutieren wir Regelsprachen zur Beschreibung von Formatüberlappungen sowie deren praktische Verwendbarkeit zur Erstellung eines Ontologie-Netzwerks zur Beschreibung von Experten.

    In a previous paper we have studied the structure of the Isobaric Analogue State (IAS) using a realistic single-particle model within a formalism that allows to disentangle real effects of isospin violations from spurious effects associated with the construction of basis states. In this work we discuss the influence of the Isovector Monopole State (IMS) on the width of the IAS. According to our results, the presence of a collective IMS is necessary to preserve the empirically found isolation of the IAS from states of the background. This is valid for a simplified harmonic oscillator model and for a realistic single-particle basis as well, since for both cases there is a strong Coulomb mixing between the IAS and the IMS, which increases at the expense of decreasing the mixing between the IAS and the {delta}N=0 configuration states. The prediction of the total width of the IAS remains in reasonable agreement with the experimental value in a calculation without free parameters.

We´ll work separately the images in the medieval world and a brief development of apocalypticism. The ultimate stage of the article will seek opportunities for dialogue between images and apocalypticism, which lead us to reflect on different iconography and apocalyptic. We ended withthe importance of “location” of the so-called object-images in relation to its function of making the absent and present practice of producing real.

    En el presente artículo se estudiará la importancia de las imágenes en el mundo medieval y en concreto en algunas representaciones vinculadas a episodios escatológicos vinculados al apocaliptismo. Estudiaremos de forma separada tanto la imagen en el mundo medieval como un breve desarrollo del apocaliptismo. El fin último del trabajo será buscar los espacios de encuentro entre las imágenes y el apocaliptismo, que nos llevarán a reflexionar sobre diferentes iconografías apocalípticas y concluir en la importancia de la “localización” de las llamadas imágenes-objeto en relación a su función de hacer presente lo ausente y ejercer de productoras de lo real.

    Ion-mobility spectroscopy (IMS) was evaluated as a high-throughput, cheap, and efficient analytical tool for detecting residues of tetrahydrocannabinol (THC) on hands. Regarding the usefulness of hand residues as potential samples for determining THC handling and abuse, we studied the correlation between data obtained from cannabis consumers who were classified as positive after saliva analysis and from those who were classified as positive on the basis of the information from hand-residue analysis. Sampling consisted of wiping the hands with borosilicate glass microfiber filters and introducing these directly into the IMS after thermal desorption. The possibility of false positive responses, resulting from the presence of other compounds with a similar drift time to THC, was evaluated and minimised by applying the truncated negative second-derivative algorithm. The possibility of false negative responses, mainly caused by competitive ionisation resulting from nicotine, was also studied. Graphical abstract THC residues: from hands to analytical signals.

    Full Text Available We have assessed how varying CO2 (180, 380, and 720 μatm and growth light intensity (40 and 400 μmol photons m−2 s−1 affected Trichodesmium erythraeum IMS101 growth and photophysiology over free iron (Fe′ concentrations between 20 and 9,600 pM. We found significant iron dependencies of growth rate and the initial slope and maximal relative PSII electron transport rates (rPm. Under iron-limiting concentrations, high-light increased growth rates and rPm; possibly indicating a lower allocation of resources to iron-containing photosynthetic proteins. Higher CO2 increased growth rates across all iron concentrations, enabled growth to occur at lower Fe′ concentrations, increased rPm and lowered the iron half saturation constants for growth (Km. We attribute these CO2 responses to the operation of the CCM and the ATP spent/saved for CO2 uptake and transport at low and high CO2, respectively. It seems reasonable to conclude that T. erythraeum IMS101 can exhibit a high degree of phenotypic plasticity in response to CO2, light intensity and iron-limitation. These results are important given predictions of increased dissolved CO2 and water column stratification (i.e., higher light exposures over the coming decades.

  15. Challenges of developing a GC/IMS based personal chemical hazard detector

    Hand-portable gas chromatography/ion mobility spectrometry (GC/IMS) techniques have been identified as a promising area of development for field and process related analytical problems. Recent development of extremely small (15 inch) personal IMS detection devices offer new prospects for creating a miniaturized GC/IMS unit. This paper provides a feasibility examination of personal GC/IMS based on the automated vapor sampling-transfer line gas chromatography (AVS-TLGC) approach previously utilized in developing hand-portable GC/IMS instrumentation. Special focus is placed upon developing low power strategies for implementing this approach. The means for achieving low power operation for extended personal use has focused on pulsed, on-demand operation of the sampling systems, low (ambient) temperature GC operation, reduced GC flow rates and pressure drops and modification of the internal IMS system flows. Development efforts to date have utilized an existing prototype miniature IMS device, the GI-MINI from Graseby Ionics coupled with modified Enviroprobe AVS-TLGC equipment developed by FemtoScan. Effect of parameters such as GC column position, temperature and carrier gas flow as well as IMS purge flows are examined for their effects upon sensitivity and resolution in breadboard GC/IMS test instrument. An evaluation of the remaining engineering hurdles limiting the development of personal GC/IMS are also presented.

    The fuel quality of maize plants is to be characterized by short, elementary and thermonalysis. The plants will be pyrolyzed in order to facilitate transport and storage. The formal kinetic parameters of three parallel reactions describing solid matter decomposition are defined by means of TG-DSC, and the reaction enthalpy is measured. Pyrolysis experiments in a rotary kiln converter in the kg range show a strong dependence of the product spectrum on process temperature. In particular, the pyrolysis gas yield increases with temperature at the expense of pyrolysis oil and water. (orig) [Deutsch] Zur energetischen Nutzung von Kulturpflanzen wird die brennstofftechnische Charakterisierung von Maispflanzen durch Kurz-, Elementar- und Thermoanalyse durchgefuehrt. Zur Reduzierung des Aufwands fuer Transport und Lagerung sollen die Pflanzen pyrolysiert weren. Mit Hilfe der TG-DSC werden formalkinetische Parameter von drei Parallelreaktionen zur Beschreibung der Feststoffzersetzung bestimmt und die Reaktionsenthalpie gemessen. Pyrolyseversuche in einem Drehrohrreaktor im Kilogramm-Massstab ergeben eine starke Abhaengigkeit des Produktspektrums von der Prozesstemperatur. Insbesondere steigt die Pyrolysegasausbeute auf Kosten der Bildung von Pyrolyseoel und Wasser mit der Temperatur stark an. (orig)

    1998-04-01

    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.

    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

    The success of secondary ion mass spectrometry (SIMS) in Geo- and Cosmo-chemistry relies on its performance in terms of: 1) very high sensitivity (mandatory for high precision measurements or to achieve low detection limits); 2) a broad mass range of elemental and isotopic species, from low mass (H) to high mass (U and above); 3) in-situ analysis of any solid flat polished surface; and 4) high spatial resolution from tens of microns down to sub-micron scale. The IMS 1300-HR3 (High Reproducibility, High spatial Resolution, High mass Resolution) is the latest generation of CAMECA's large geometry magnetic sector SIMS (or ion microprobe), successor to the internationally recognized IMS 1280-HR. The 1300-HR3delivers unmatched analytical performance for a wide range of applications (stable isotopes, geochronology, trace elements, nuclear safeguards and environmental studies…) due to: • High brightness RF-plasma oxygen ion source with enhanced beam density and current stability, dramatically improving spatial resolution, data reproducibility, and throughput • Automated sample loading system with motorized sample height (Z) adjustment, significantly increasing analysis precision, ease-of-use, and productivity • UV-light microscope for enhanced optical image resolution, together with dedicated software for easy sample navigation (developed by University of Wisconsin, USA) • Low noise 1012Ω resistor Faraday cup preamplifier boards for measuring low signal intensities In addition, improvements in electronics and software have been integrated into the new instrument. In order to meet a growing demand from geochronologists, CAMECA also introduces the KLEORA, which is a fully optimized ion microprobe for advanced mineral dating derived from the IMS 1300-HR3. Instrumental developments as well as data obtained for stable isotope and U-Pb dating applications will be presented in detail.

    Full Text Available El objetivo de este artículo es brindar al clínico pautas para el uso racional y adecuado de los avances tecnológicos en imaginología, para de esta manera lograr un criterio multidisciplinario en el momento de tomar una decisión buscando el beneficio del paciente sin someterlo a exámenes de poca utilidad. Se realizó una búsqueda sistemática de la literatura médica acerca de la cefalea abarcando su fisiopatología, clasificación y, específicamente, el uso de imágenes diagnósticas. Para ello se hizo búsqueda en diferentes bases de datos según las palabras claves indicadas. El abordaje clínico y la diferenciación entre el tipo de cefalea es primordial para decidir el beneficio y la necesidad del uso de imágenes diagnósticas. Las neuroimágenes no son comúnmente solicitadas en pacientes con cefalea primaria, se comienza la sospecha clínica ante la presencia de señales de alarma. Las cefaleas secundarias requieren un estudio más extenso en los cuales se incluye la toma de imágenes radiológicas. Teniendo en cuenta los beneficios de la TC y la RM que se exponen en esta revisión, la TC es preferida en situaciones de urgencia, y para aquellas que no lo son, la RM es más adecuada.

    Silicene, the new supernova material Silicon is formed in a large amount during supernova nucleo-synthesis and it is the 8th most common chemical element in the universe. Today modern electronics make large use of bulk silicon, which has consequently an extremely large impact on the world industry and economy. The need for more powerful, faster and less energy-consuming integrated circuits requires in the future the use of nanotechnologies. The ultimate step concerning silicon is silicene (the 2D silicon-based analogue of graphene). This material is of paramount importance as it requires the use of the same technologies and production lines as silicon. Even if theoreticians had predicted its possible existence, it is only in 2010 that a team of pioneers from CINAM-France, ISMO-France and UCF-USA has presented for the first time the experimental evidence of the formation of silicene. Since then research is exploding (like a supernova!) both on the experimental and theoretical sides, with the main aim of replacing bulk silicon with this potentially revolutionary material. However, before any possible industrial use, it has first to be prepared or synthesized in various stripe and sheet shapes on insulating surfaces on which its physical and chemical properties have to be analyzed in detail. A second step is its chemical functionalization through various dopants to achieve different tasks, expected or not yet imagined. Chemists and physicists, experimentalists and theoreticians are involved in this thrilling work. A wide array of techniques, from the subtle chemistry reaction networks, to all those of experimental surface science (from synchrotron radiation to scanning tunneling microscopy) as well as those of theoretical chemistry (from {\\it ab initio} to density functional theory calculations) are involved. Big progress has been made since 2010 and the success of this third International Meeting on Silicene (IMS-3) is demonstrated by the present proceedings

    Full Text Available Dieser Beitrag soll die Forschungslücke zur Darstellung von Behinderungen speziell im Kinderfilm im deutschsprachigen Raum füllen. 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 [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.

    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.

    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.

    The role of wind power in the industrial sector currently depends very much on its technical and economic integrability in existing conventional supply structures. The most important questions in this context relate to capacity effects, adapted operating methods of conventional power suppliers, and, most important of all, operational energy production costs. In some regions alternative energy supply concepts are not yet or not sufficiently available. However, these will nevertheless offer ways of installing energy systems with a large renewable segment. The chances of bringing such projects to fruition depend for one thing on the climate, which may either stimulate or deter from development work on renewables (wind power, solar energy), and for another, often in apparent opposition to the former, on the oftentimes poorly developed infrastructure and economic strength of the region in question. [Deutsch] Die Bedeutung der Windenergienutzung im industrialisierten Bereich ist derzeit verknuepft mit deren technischen und oekonomischen Integrationsfaehigkeit in bestehende, konventionelle Versorgungsstrukturen. Im Vordergrund steht hierbei die Klaerung der Fragestellungen nach Kapazitaetseffekten, angepassten Betriebsweisen konventioneller Stromerzeuger und, in erster Linie, betriebswirtschaftlichen Energieerzeugungskosten. Derzeit bieten die Regionen, in denen eine anderweitige Versorgung noch nicht oder in nicht ausreichendem Masse existieren Moeglichkeiten zur Installation von Energiesystemen mit hoher regenerativer Durchdringung. Fuer die Realisation solcher Projekte stehen sich haeufig die klimatischen Bedingungen, die einerseits z.T. die Ursache fuer den geringen Entwicklungsstand sind, andererseits aber auch guenstige Voraussetzungen fuer die Nutzung regenerativer Energien (Wind, Sonne) bieten, der meist schlechten Infrastruktur und der geringen Wirtschaftskraft gegenueber.

    NASA and ESA are planning the joint Europa Jupiter System Mission (EJSM) to the Jupiter system with specific emphasis to Europa and Ganymede, respectively. The Japanese Space Agency is also planning an orbiter mission to explore Jupiter's magnetosphere and the Galilean satellites. For NASA's Jupiter Europa Orbiter (JEO) we are developing the 3D Ion Mass Spectrometer (IMS) with two main goals which can also be applied to the other Galilean moons, 1) measure the plasma interaction between Europa and Jupiter's magnetosphere and 2) infer the 4n surface composition to trace elemental [1] and significant isotopic levels. The first goal supports the magnetometer (MAG) measurements, primarily directed at detection of Europa's sub-surface ocean, while the second gives information about transfer of material between the Galilean moons, and between the moon surfaces and subsurface layers putatively including oceans. The measurement of the interactions for all the Galilean moons can be used to trace the in situ ion measurements of pickup ions back to either Europa's or Ganymede's surface from the respectively orbiting spacecraft. The IMS instrument, being developed under NASA's Astrobiology Instrument Development Program, would maximally achieve plasma measurement requirements for JEO and EJSM while moving forward our knowledge of Jupiter system composition and source processes to far higher levels than previously envisaged.

    The CTBT International Monitoring System is to be comprised of 337 facilities located all over the world for the purpose of detecting and locating nuclear test explosions. Major challenges remain, namely the completion of the network where most of the remaining stations have either environmental, logistical and/or political issues to surmont (89% of the stations have already been built) and the sustainment of a reliable and state-of the-art network covering 4 technologies - seismic, infrasound , hydroacoustic and radionuclide. To have a credible and trustworthy verification system ready for entry into force of the Treaty, the CTBTO is protecting and enhancing its investment of its global network of stations and is providing effective data to the International Data Centre (IDC) and Member States. Regarding the protection of the CTBTO's investment and enhanced sustainment of IMS station operations, the IMS Division is enhancing the capabilities of the monitoring system by applying advances in instrumentation and introducing new software applications that are fit for purpose. Some examples are the development of noble gas laboratory systems to process and analyse subsoil samples, development of a mobile noble gas system for onsite inspection purposes, optimization of Beta Gamma detectors for Xenon detection, assessing and improving the efficiency of wind noise reduction systems for infrasound stations, development and testing of infrasound stations with a self-calibrating capability, and research into the use of modular designs for the hydroacoustic network.

    Morávek P

    2002-01-01

    Full Text Available Einleitung: Die Ansicht über eine radikale Operation bei Nierenkarzinom mit einer Tumorthrombose im rechten Herzvorhof ist in der Literatur bisher kontrovers. Nach Meinung der Autoren ist der Tumorthrombus in erster Linie ein ernsthaftes Problem der Operabilität. Sie entschieden sich für eine radikale Operation. Methode: Die Autoren operierten 11 Patienten im Zeitraum von 1978 bis 2001. Die grundlegenden Bedingungen für eine Operation waren die exakte Festlegung der Diagnose und des Stadiums der Erkrankung (T1-T3, N0, M0. Bei 9 Patienten haben die Autoren eine Entfernung des Tumorthrombus in extrakorporaler Zirkulation bei Kreislaufstillstand und bei 2 Kranken mittels kavoatrialem Shunt ohne Herz-Lungen-Maschine durchgeführt. Ergebnisse: 2 Patienten sind in der 2. bis 4. Woche nach der Operation gestorben, 1 Patientin ist 2 Jahre nach der Operation gestorben, 1 Patient ist nach 4 Jahren und 1 Patient nach 8 Jahren gestorben. 6 Patienten leben 1, 2, 3, 3,5, 3,5 und 5 Jahre nach der Operation. Schlußfolgerung: Die Voraussetzungen für eine erfolgreiche Operation sind die richtige Indikation, die Wahl der passenden Operationsmethode sowie die Zusammenarbeit von Urologen und Kardiochirurgen. Die Autoren halten eine Entfernung des Thrombus mittels Atriotomie sowie Kavotomie in extrakorporaler Zirkulation und tiefer Hypothermie mit Kreislaufstillstand für die beste Methode.

    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.)

    To investigate the frequency of valid yet suboptimal Immediate Postconcussion Assessment and Cognitive Test© (ImPACT) performance in university athletes and to explore the benefit of subsequent ImPACT administrations. This descriptive laboratory study involved baseline administration of ImPACT to 769 university athletes per the institution's concussion management protocol. Testing was proctored in groups of ≤ 2 participants. Participants who scored below the 16th percentile according to ImPACT normative data were re-administered ImPACT up to two additional times as these scores were thought to be potentially indicative of suboptimal effort or poor understanding of instructions. Descriptive analyses were used to examine validity indicators and individual Verbal and Visual Memory, Visual Motor Speed and Reaction Time ImPACT composite scores in initial and subsequent administrations. Based on ImPACT's validity criteria, 1% (9/769) of administrations were invalid and 14.6% (112/769) had one or more composite score 16th percentile. Clinicians must be aware of suboptimal ImPACT performance as it limits the clinical utility of the baseline assessment. Further research is needed to address factors leading to 'valid' but invalid baseline performance.

    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)

  5. The Applicability of Incoherent Array Processing to IMS Seismic Arrays

    2014-03-01

    The seismic arrays of the International Monitoring System (IMS) for the Comprehensive Nuclear-Test-Ban Treaty (CTBT) are highly diverse in size and configuration, with apertures ranging from under 1 km to over 60 km. Large and medium aperture arrays with large inter-site spacings complicate the detection and estimation of high-frequency phases lacking coherence between sensors. Pipeline detection algorithms often miss such phases, since they only consider frequencies low enough to allow coherent array processing, and phases that are detected are often attributed qualitatively incorrect backazimuth and slowness estimates. This can result in missed events, due to either a lack of contributing phases or by corruption of event hypotheses by spurious detections. It has been demonstrated previously that continuous spectral estimation can both detect and estimate phases on the largest aperture arrays, with arrivals identified as local maxima on beams of transformed spectrograms. The estimation procedure in effect measures group velocity rather than phase velocity, as is the case for classical f-k analysis, and the ability to estimate slowness vectors requires sufficiently large inter-sensor distances to resolve time-delays between pulses with a period of the order 4-5 s. Spectrogram beampacking works well on five IMS arrays with apertures over 20 km (NOA, AKASG, YKA, WRA, and KURK) without additional post-processing. Seven arrays with 10-20 km aperture (MJAR, ESDC, ILAR, KSRS, CMAR, ASAR, and EKA) can provide robust parameter estimates subject to a smoothing of the resulting slowness grids, most effectively achieved by convolving the measured slowness grids with the array response function for a 4 or 5 s period signal. Even for medium aperture arrays which can provide high-quality coherent slowness estimates, a complementary spectrogram beampacking procedure could act as a quality control by providing non-aliased estimates when the coherent slowness grids display

    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.

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

  7. Ultrawideband SAR processing with the Range Migration Algorithm and the ImSyn processor

    Phillips, Louis C.; Eichel, Laurence A.; Evanko, Stephen M.

    1996-11-01

    The ImSynTM Processor is an optoelectronic signal processor developed by Essex Corporation to accelerate coherent imaging processes. This paper focuses on the application of the ImSyn Processor to SAR imaging where severe range differential curvature is present. This occurs in SAR systems imaging large scenes with fine resolution, foliage penetrating (FOPEN) radar and ground penetrating radar. Application of the range migration algorithm removes the differential range curvature but results in a non- uniform or warped frequency space. The ImSyn processor operates directly on the frequency data permitting a discrete Fourier transform in warped frequency space without data interpolation. Both the range migration algorithm and the standard polar formatting algorithm benefit from the increased speed and resolution available from the ImSyn processor. A discussion of the ImSyn processor, the range migration algorithm and an example of a FOPEN image processed on our prototype system are presented.

    According to its proponents, the Intelligent Manufacturing System is a highly efficient, global production system, designed as the first decisive step in ensuring that society will continue to flourish materially and spiritually. It is the gateway to advanced manufacturing and processing technologies, represented by a project-based, industry-led, government-endorsed program of cooperative research, carried out in seven industrially advanced regions of the world (Australia, Canada, Europe, Japan, Switzerland, USA, Korea). Currently, there are projects worth about $250 million in progress involving 200+ companies and 200+ research institutions. The benefits of IMS sponsorship, and the type of projects carried on as part of the program (e.g. projects dealing with total product life cycle issues, process issues, strategy/planning /design tools, human/organisation/social issues, virtual/extended enterprise issues) are discussed.

    Full Text Available Knowledge management in organizations, the learning objects paradigm, the advent of a new web generation, and the “Semantic Web” are major actual trends that reveal a potential for a renewed distance learning pedagogy. First and foremost is the use of educational modelling languages and instructional engineering methods to help decide how to aggregate learning objects in learning and knowledge management environments. This article proposes a set of tools under implementation, such as a graphic Learning Design Editor and a delivery system, using learning object repositories to create IMS-LD online environments. We also propose a strategy for the deployment of learning design tools and methods in learning organizations.

    Experimental amorphous Al{sub 2}O{sub 3}CaO fibers (<80% Al{sub 2}O{sub 3}) which had been made by inviscid melt spinning (IMS) of low viscosity melts were found to retain up to 87% of their room temperature tensile strength at 750{degree}C (versus 25% for S-glass). The results suggest that the strength of these fibers is ultimately limited by their crystallization temperatures and that they might tolerate 100-200{degree}C higher temperatures than S-glass in comparable applications (e.g., in fiber reinforced composites). Some fibers were crystallized in a laboratory furnace. The crystalline phases of the resulting fibers were correlated with measured properties. The implications were applied to an analysis of a proposed process for redrawing inviscid melt spun (RIMS) fibers.

    Mitsubishi Electric has produced and delivered to the Institute of Molecular Science (IMS) a magnetic-power-source system for ultraviolet synchrotron orbital radiation (UVSOR). High precision is required of power sources for all such systems, but this is particularly so for the magnetic-power-source of a synchrotron. The specifications for this synchrotron required the generation of a linear current in the coil of 0--1,200A within 150ms with less than a +-0.2% error over a 2.5--100% range. This accuracy was achieved by employing high-stability control circuits using main circuits of 24 thermistors and high-frequency multiple choppers along with a high-speed 16-bit analog-to-digital converter.

    2011-03-01

    Sandia National Laboratories (SNL) developed the Integrated Verification System Evaluation Model (IVSEM) to estimate the performance of the International Monitoring System (IMS) operated by the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO). IVSEM was developed in several phases between 1995 and 2000. The model was developed in FORTRAN with an IDL-based user interface and was compiled for Windows and UNIX operating systems. Continuing interest in this analysis capability, coupled with numerous advances in desktop computer hardware and software since IVSEM was written, enabled significant improvements to IVSEM run-time performance and data analysis capabilities. These improvements were implemented externally without modifying the FORTRAN executables, which had been previously verified. This paper describes the parallelization approach developed to significantly reduce IVSEM run-times and the new test setup and analysis tools developed to facilitate better IVSEM operation.

    SUMMARY RATIONALE The IMS I and II pilot trials demonstrated that the combined intravenous (IV) and intra-arterial (IA) approach to recanalization may be more effective than standard IV rt-PA (Activase®) alone for moderate-to-large (NIHSS ≥10) strokes, and with a similar safety profile. AIMS The primary objective of this NIH-funded, Phase III, randomized, multi-center, open-label clinical trial is to determine whether a combined IV/IA approach to recanalization is superior to standard IV rt-PA alone when initiated within three hours of acute ischemic stroke onset. The IMS III Trial will develop and maintain a network of interventional centers to test the safety, feasibility, and potential efficacy of new FDA-approved catheter devices as part of a combined IV/IA approach to recanalization as the IMS III Study progresses. A secondary objective of the IMS III Trial is to determine the cost-effectiveness of the combined IV/IA approach as compared to standard IV rt-PA. Trial enrollment began in July of 2006. DESIGN A projected 900 subjects with moderate-to-large (NIHSS ≥10) ischemic strokes between ages 18–80 will be enrolled over the next 5 years at 40+ centers in the United States and Canada. Patients must have IV treatment initiated within three hours of stroke onset inn both arms. Subjects will be randomized in a 2:1 ratio with more subjects enrolled in the combined IV/IA group. The IV rt-PA alone group will receive the standard full dose (0.9 mg/kg, 90 mg max [10% as bolus]) of rt-PA intravenously over an hour. The combined IV/IA group will receive a lower dose of IV rt-PA (~ 0.6 mg/kg, 60 mg max) over 40 minutes followed by immediate angiography. If a treatable thrombus is not demonstrated, no IA therapy will be administered. If an appropriate thrombus is identified, treatment will continue with either the Concentric Merci® thrombus-removal device, infusion of rt-PA and delivery of low-intensity ultrasound at the site of the occlusion via the EKOS® Micro

    In order to increase the accuracy of the current control loop, usually, well known parameter compensation and/or cross decoupling techniques are employed for advanced ac drives. In this paper, instead of using these techniques an observer-based current controller is proposed for vector controlled...... induction motor (IM) drives. The control design, based on synchronously rotating d-q frame model of the machine, has a simple structure that combines the proportional portion of a conventional PI control and output of the observer. The observer is predicted to estimate the disturbances caused by parameters...... change in current control loop and, also to remove undesired cross coupling existing between components of the stator current. The observer uses the measured stator currents and estimated PWM voltages, and produces a disturbance signal with a low pass filter. The proposed control scheme reduces cross...

    2001-01-01

    Heavy ion beam transport through the containment chamber plays a crucial role in all heavy ion fusion (HIF) scenarios. Here, several parameters are used to characterize the operating space for HIF beams; transport modes are assessed in relation to evolving target/accelerator requirements; results of recent relevant experiments and simulations of HIF transport are summarized; and relevant instabilities are reviewed. All transport options still exist, including (1) vacuum ballistic transport, (2) neutralized ballistic transport, and (3) channel-like transport. Presently, the European HIF program favors vacuum ballistic transport, while the US HIF program favors neutralized ballistic transport with channel-like transport as an alternate approach. Further transport research is needed to clearly guide selection of the most attractive, integrated HIF system

Denn gerade Neue Medien motivieren, fördern selbstständiges und reflexives Lernen, gestatten neue Unterrichtskonzepte und ermöglichen die Integration authentischer Probleme in Lernsituationen. Beispielhaft wird in diesem Beitrag aufgezeigt, wie Lernen und Lehren mit Neuen Medien mithilfe des Konzepts der Islamstunde im islamischen Religionsunterricht umgesetzt werden kann. Learning and teaching with new media in Islamic religious instruction Scholastic confessional religious instruction has a considerable joint responsibility when it comes to the upbringing and education of generations to come. That is why Islamic religious instruction in Austria too has been seeking to stay engaged in the latest discourse on religious education and its teaching principles through both the publication of the new and skills-based Islamstunde [Islamic religious class] schoolbook series and the inclusion of media-related and didactic innovations in the concept. Precisely because new media motivate, facilitate independent and reflective learning, allow new teaching concepts and enable the integration of authentic problems into learning situations. The present article illustrates, by way of example, how learning and teaching with new media can be implemented in Islamic religious instruction by drawing on the concept as presented in Islamstunde.

  3. Observed and predicted performance of the global IMS infrasound network

    Le Pichon, A.; Ceranna, L.; Landes, M.

    2012-04-01

    The International Monitoring System (IMS) infrasound network is being deployed to monitor compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Global-scale analyses of data recorded by this network indicate that the detection capability exhibits strong spatio-temporal variations. Previous studies estimated radiated acoustic source energy from remote infrasound observations using empirical yield-scaling relations, which account for the along-path stratospheric winds. Although the empirical wind correction reduces the variance in the explosive energy versus pressure relationship, large error remains in the yield estimates. Numerical modeling techniques are now widely employed to investigate the role of different factors describing atmospheric infrasound sources and propagation. Here we develop a theoretical attenuation relation from a large set of numerical simulations using the Parabolic Equation method. This relation accounts for the effects of the source frequency; geometrical spreading and dissipation; and realistic atmospheric specifications on the pressure wave attenuation. Compared with previous studies, the derived attenuation relation incorporates a more realistic physical description of infrasound propagation. By incorporating real ambient noise information at the receivers, we obtain the minimum detectable source amplitude in the frequency band of interest for detecting explosions. Empirical relations between the source spectrum and explosion yield are used to infer detection thresholds in tons of TNT equivalent. In the context of future verification of the CTBT, the obtained attenuation relation provides a more realistic picture of the spatio-temporal variability of the IMS network performance. The attenuation relation could also be used in the design and maintenance of an arbitrary infrasound monitoring network.

    The article presents a comprehensive, comparative analysis of various national schemes existing or being negotiated in EC member states for (negotiated) third-party access to power distribution systems and use-of-system pricing for power transmission transactions in the deregulated EU internal market in electricity, in order to elaborate and discuss aspects of improvement of the current German TPA scheme adopted by the industrial associations involved. The countries referred to for reasons of comparison are England and Wales, Norway, Sweden and Finnland, as well as Austria, which adopted a concept tailored rather to Austrian conditions than to the framework defined by the EU Internal Market Directive. (orig./CB) [German] In Deutschland wurde die Binnenmarktrichtlinie fuer Elektrizitaet bereits fruehzeitig mit einer Energierechtsreform im April 1998 und einer Kartellrechtsreform zum Januar 1999 umgesetzt. Der Diskussionsstand zum Zeitpunkt des Abfassens dieses Beitrags liess darauf schliessen, dass mit der neuen Verbaendevereinbarung ein Schritt in Richtung hoeherer Netznutzungstransparenz gelingt, fundamentale Bedenken aber bestehen bleiben. Aus diesen Grund erscheint eine Analyse von Ineffizienzen im deutschen Netzzugangssystem sinnvoll. Um das deutsche System nicht an theoretischen Modellen sondern an den Massstaeben praktikabler (weitgehend effizienter) Netzzugangsregimes zu messen, wird ein Vergleich mit Laendern mit laengerer Liberalisierungserfahrung herangezogen (England und Wales, Norwegen, Schweden, Finnland). Die Perspektive wird ergaenzt um das oesterreichische Konzept, das sich eher defensiv an die Vorgaben der Binnenmarktrichtlinie fuer Elektrizitaet anlehnt. Ein institutioneller und oekonomischer Vergleich der ausgewaehlten Netzzugangs- und Regulierungssysteme zeigt, dass der ordnungsrechtliche Rahmen fuer die Stromuebertragung und -verteilung im Zuge der Liberalisierung in den einzelnen Laendern im Prinzip unabhaengig von der Versorgungsstruktur

    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.

  14. Membrane transport mechanism 3D structure and beyond

    CERN Document Server

    Ziegler, Christine

    2014-01-01

    This book provides a molecular view of membrane transport by means of numerous biochemical and biophysical techniques. The rapidly growing number of atomic structures of transporters in different conformations and the constant progress in bioinformatics have recently added deeper insights.   The unifying mechanism of energized solute transport across membranes is assumed to consist of the conformational cycling of a carrier protein to provide access to substrate binding sites from either side of a cellular membrane. Due to the central role of active membrane transport there is considerable interest in deciphering the principles of one of the most fundamental processes in nature: the alternating access mechanism.   This book brings together particularly significant structure-function studies on a variety of carrier systems from different transporter families: Glutamate symporters, LeuT-like fold transporters, MFS transporters and SMR (RND) exporters, as well as ABC-type importers.   The selected examples im...

    Force mode microscopy can be used to examine the effect of mechanical manipulation on the noncovalent interactions that stabilize proteins and their complexes. Here we describe the effect of complexation by the high affinity protein ligand E9 on the mechanical resistance of the simple four-helical protein, Im9. When concatenated into a construct of alternating I27 domains, Im9 unfolded below the thermal noise limit of the instrument ( approximately 20 pN). Complexation of E9 had little effect on the mechanical resistance of Im9 (unfolding force approximately 30 pN) despite the high avidity of this complex (K(d) approximately 10 fM).

    , they represent valuable data for other civil applications like monitoring of natural hazards (volcanic activity, storm tracking) and climate change. Non-noise detections are used in network processing at the IDC along with seismic and hydroacoustic technologies. The arrival phases detected on the three waveform technologies may be combined and used for locating events in an automatically generated bulletin of events. This automatic event bulletin is routinely reviewed by analysts during the interactive review process. However, the fusion of infrasound data with the other waveform technologies has only recently (in early 2010) become part of the IDC operational system, after a software development and testing period that began in 2004. The build-up of the IMS infrasound network, the recent developments of the IDC infrasound software, and the progress accomplished during the last decade in the domain of real-time atmospheric modelling have allowed better understanding of infrasound signals and identification of a growing data set of ground-truth sources. These infragenic sources originate from natural or man-made sources. Some of the detected signals are emitted by local or regional phenomena recorded by a single IMS infrasound station: man-made cultural activity, wind farms, aircraft, artillery exercises, ocean surf, thunderstorms, rumbling volcanoes, iceberg calving, aurora, avalanches. Other signals may be recorded by several IMS infrasound stations at larger distances: ocean swell, sonic booms, and mountain associated waves. Only a small fraction of events meet the event definition criteria considering the Treaty verification mission of the Organization. Candidate event types for the IDC Reviewed Event Bulletin include atmospheric or surface explosions, meteor explosions, rocket launches, signals from large earthquakes and explosive volcanic eruptions.

    Numerous signals will be routinely detected using the 60 array, global IMS (International Monitoring System) infrasound network. Infrasonic signals are sub-audible quasi longitudinal, atmospheric waves in the frequency band from about 10 Hz to -5 minutes in period (limited by human acoustic audibility in the high frequency limit and by the wave-guide acoustic cut-off frequency and the Brunt Vaisalla frequency in the low frequency limit) These small amplitude waves are a natural subset of the well-known atmospheric acoustic-gravity wave regime which has been identified from the linearized equations of geophysical fluid mechanics in the flat earth approximation, neglecting the earth's rotation, etc. For the IMS network the instrumental pressure sensor response was chosen to range from -4 to 0.02 Hz. These are ground-based arrays of typically 4 to 9 sensors with separations of about 1-2 km between the array elements. Examples of naturally occurring impulsive sources of infrasound include volcanic eruptions, earthquakes, bolides (large meteor-fireballs entering the atmospheric at very high speeds up to -300 times faster than ground-level sound waves), microbaroms (the 'voice of the sea' due to the interaction of atmospheric storms and surface ocean waves) and the supersonic motion of the auroral electrojet at about 100 km altitude (auroral infrasonic waves), etc. In this paper we will briefly summarize our current state of knowledge of infrasound signals from bolides. This summary will include the generation of the signals at the complex, quasi-cylindrical line source, to the refraction and diffraction of the propagating waves by the middle atmospheric and tropospheric temperature and wind systems and finally, the detection of the signals and their interpretation by inferring the source properties, Le., source altitude, blast radius (see below) and the source energy, etc. In addition, we will use infrasound from energetic bolides to estimate the expected

    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.)

E-mail: georgiamode@hotmail.com Intestinal neoplasms are uncommon in dogs, and among the most frequently diagnosed are smooth muscle, lymphomas and carcinomas. The fibrosarcoma is extremely rare in the intestine of animals of this species therefore, little is known about the macroscopic and behavior of this tumor. Given this unusual intestinal disease in dogs, the present study aimed to report a case of intestinal fibrosarcoma in a poodle breed dog, 15 years old, with no apparent clinical signs. The mass was pedunculated, whitish and firm consistency. The diagnosis was made by histopathology. After four months of surgical excision, there was no recurrence and metastasis. We conclude that the intestinal fibrosarcoma has low aggressiveness, are rare and can present macroscopic pediculated.

The ability of immobilised lipase (Lipozyme IM-77 from Rhizomucor miehei to catalyse the transesterification of hexanol and tributyrin was investigated in this study. Response surface methodology (RSM and five-level-five-factor central composite rotatable design (CCRD were employed to evaluate the effects of synthesis parameters, such as reaction time (2 to 10 h, temperature (25 to 65 °C, enzyme amount (10 to 50 %, substrate amount (in mol ratio of tributyrin to hexanol (1:1 to 3:1, and added water content (0 to 20 %, on percentage amount (in mol conversion of hexyl butyrate by transesterification. Reaction time and enzyme amount were the most important variables and substrate amount (in mol ratio had less effect on the percentage of amount (in mol conversion. Based on canonical analysis, the optimum synthesis conditions were: reaction time 8.3 h, temperature 50 °C, enzyme amount 42.7 %, substrate amount (in mol ratio 1.8:1, and added water 12.6 %. The predicted value was 96.2 % and actual experimental value 95.3 % of the amount (in mol conversion.

    Do we need the fire brigade in a power plant? This question is to be answered in the affirmative. The fire brigade, in addition, is of greater use than it costs. Decisive for the formation and structure of a fire brigade are the hazard potential of the respective plant and its organisational structure. The bases must be defined in close cooperation between operator and approving authority. The striking force of the works internal fire protection depends on the incorporation of the fire brigade into the power plant organisation. Provided the synthesis is optimal - consisting of preventive fire protection, defensive fire protection, technical aid and possible rescue service - the fire brigade will make a decisive contribution to the long-term operating results of a power plant. (orig.) [German] Brauchen wir im Kraftwerk eine Feuerwehr? Diese Frage ist mit 'Ja' zu beantworten - und die Feuerwehr leistet darueber hinaus mehr, als sie kostet. Ausschlaggebend fuer den Aufbau und die Struktur der Feuerwehr ist das Gefaehrdungspotential des jeweiligen Betriebes und dessen Organisationsstruktur. Die Ausgangspunkte muessen in enger Abstimmung zwischen Betreiber und Genehmigungsbehoerde definiert werden. Entscheidend fuer die Schlagkraft des betrieblichen Brandschutzes ist eine entsprechende Einbindung der Organisationseinheit Feuerwehr in die Kraftwerksorganisation. Bei einer optimalen Synthese, bestehend aus vorbeugendem Brandschutz, abwehrendem Brandschutz, technischer Hilfeleistung und eventuellem Rettungsdienst, leistet eine Feuerwehr einen entscheidenden Beitrag zum langfristigen Betriebsergebnis einer Kraftwerksanlage.

    We review the physical characteristics and temporal development of a significant IMS magnetospheric event: the sudden commencement and multiple substorms of July 29, 1977. An interplanetary shock, superimposed on relatively high solar wind densities, forces the magnetopause at 0027 UT in past the position of GEOS 1(approx.6.7 R/sub E/). Following this compression, as well as periods of southward IMF, a series of substorms culminated in a very large substorm with peak electrojet current at 1230 UT, followed by a relatively quiet recovery phase. The ring current showed a maximum at 0600 UT and a major perturbation at 1230 UT corresponding to the last substorm. A large suite of international data were analyzed for this event, concluding in a computerized data analysis workshop (CDAW 2) in October 1979. Included in the analysis are results from eleven spacecraft, seven ground arrays, several numerical models, and theoretical calculations. Emphasis on the analysis was on the physical processes of energy transfer and magnetospheric dynamics. We describe the CDAW analysis and present an overview description of the event, including the solar wind conditions and magnetospheric response, as an introduction to this series of papers.

    A subretinal visual implant (Alpha IMS, Retina Implant AG, Reutlingen, Germany) was implanted in 29 blind participants with outer retinal degeneration in an international multicenter clinical trial. Primary efficacy endpoints of the study protocol were a significant improvement of activities of daily living and mobility to be assessed by activities of daily living tasks, recognition tasks, mobility, or a combination thereof. Secondary efficacy endpoints were a significant improvement of visual acuity/light perception and/or object recognition (clinicaltrials.gov, NCT01024803). During up to 12 months observation time twenty-one participants (72%) reached the primary endpoints, of which thirteen participants (45%) reported restoration of visual function which they use in daily life. Additionally, detection, localization, and identification of objects were significantly better with the implant power switched on in the first 3 months. Twenty-five participants (86%) reached the secondary endpoints. Measurable grating acuity was up to 3.3 cycles per degree, visual acuities using standardized Landolt C-rings were 20/2000, 20/2000, 20/606 and 20/546. Maximal correct motion perception ranged from 3 to 35 degrees per second. These results show that subretinal implants can restore very-low-vision or low vision in blind (light perception or less) patients with end-stage hereditary retinal degenerations.

    Evaluation of infrasonic detection capability for the International Monitoring System of the Comprehensive Test Ban Treaty (IMS/CTBT) is made with respect to signal analysis and global coverage. Signal analysis is anecdotally reviewed with respect to composite power, correlation and F-statistic detection algorithms. In the absence of adaptive pre-filtering, either cross-correlation or F-statistic detection is required. As an unbounded quantity, the F-statistic offers potentially greater sensitivity to signals of interest. With PURE state pre-filtering, power detection begins to become competitive with correlation and F-statistic detection. Additional application of simple post-filters of minimum duration and maximum bearing deviation results in unique positive detection of an identified impulsive infrasonic signal. Global coverage estimates are performed as a useful deterministic evaluation of networks, offering an easily interpreted network performance, which compliments previous probabilistic network evaluations. In particular, adequate coverage (2 sites), uniform coverage, and redundant coverage (3 to 4 sites) provide figures of merit in evaluating detection, location and vulnerability, respectively. Coverage estimates of the I60 network have been performed which indicate generally adequate coverage for the majority of the globe. Modest increase of station gain (increase of number of elements from 4 to 7) results in significant increase in coverage for mean signal values. Ineffective sites and vulnerability sites are identified which suggest further refinement of the network is possible.

    Full Text Available In the current networking field many research works are going on regarding the integration of different wireless technologies, with the aim of providing uninterrupted connectivity to the user anywhere, with high data rates due to increased demand. However, the number of objects like smart devices, industrial machines, smart homes, connected by wireless interface is dramatically increasing due to the evolution of cloud computing and internet of things technology. This Paper begins with the challenges involved in such integrations and then explains the role of different couplings and different architectures. This paper also gives further improvement in the LTE and Wimax integration architectures to provide seamless vertical handover and flexible quality of service for supporting voice, video, multimedia services over IP network and mobility management with the help of IMS networks. Evaluation of various parameters like handover delay, cost of signalling, packet loss,, is done and the performance of the interworking architecture is analysed from the simulation results. Finally, it concludes that the cross layer scenario is better than the non cross layer scenario.

    Thomas Rucker

    2014-02-01

    Full Text Available Johann Friedrich Herbart (1776-1841 gilt als der Begründer der wissenschaftlichen Pädagogik. In diesem Beitrag wird zu zeigen versucht, dass Herbart die Unterstützung politischer Bildung als eine Aufgabe von Regierung, Unterricht und Zucht bestimmt und in seinem Werk wichtige „Bausteine“ für eine Theorie der politischen Bildung unter den Bedingungen von Erziehung vorlegt hat. Nach Herbart ist das politische Selbst- und Weltverhältnis auf Sachverhalte bezogen, die nicht nur die Lebensführung einzelner Menschen, sondern die Lebensführung einer Mehrzahl von Menschen betreffen. Nicht das Zusammenleben von Menschen generell ist jedoch Orientierungsgesichtspunkt des politischen Selbst- und Weltverhältnisses, sondern nur das problematisch gewordene Zusammenleben. Politik ergibt sich nach Herbart aus einem Konflikt hinsichtlich der Frage, wie das Zusammenleben von Menschen geregelt sein sollte. Während die Regierung lediglich mittelbar einen Beitrag zur politischen Bildung leistet, indem sie die Voraussetzungen für Unterricht und Zucht bereitstellt, fungieren die beiden zuletzt genannten Formen von Erziehung als die eigentlichen Medien, in denen die politische Bildung im Sinne Herbarts ihren Ort hat.

    2017-11-01

    MALDI (matrix assisted laser desorption ionization) Imaging Mass Spectrometry (IMS) allows molecular analysis of biological materials making possible the identification and localization of molecules in tissues, and has been applied to address many questions on skin pathophysiology, as well as on studies about drug absorption and metabolism. Sample preparation for MALDI IMS is the most important part of the workflow, comprising specimen collection and preservation, tissue embedding, cryosectioning, washing, and matrix application. These steps must be carefully optimized for specific analytes of interest (lipids, proteins, drugs, etc.), representing a challenge for skin analysis. In this review, critical parameters for MALDI IMS sample preparation of skin samples will be described. In addition, specific applications of MALDI IMS of skin samples will be presented including wound healing, neoplasia, and infection. Copyright © 2017 Elsevier B.V. All rights reserved.

    To conduct comprehensive and advanced analyses of nuclear tests, like those in the DPRK, data from different monitoring technologies are required. Over the past twenty years, the CTBTO has successfully built-up the CTBT IMS network to 90% completion and it ensures that the network is operational to strict standards enabling its data to be used for such purposes. This presentation will reflect on the detection capabilities of the four different IMS monitoring technologies (Seismic, Hydroacoustic, Infrasound and Radionuclide) during the three recent DPRK nuclear tests in 2016-2017. Also an analysis of the impact that IMS station data availability had on the overall detection capability and ongoing efforts to further enhance IMS network data availability will be shown.

    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.

  4. A Base Solution for Exposing IMS Telecommunication Services to Web 2.0 Enabled Applications

    Science.gov (United States)

    Deinert, Florian; Murarasu, Alin; Bachmann, Andreas; Magedanz, Thomas

    The convergence of telecommunication and Web 2.0 services is leading to new opportunities for the telecommunications market. Companies are looking for ways to include their services in Web 2.0 applications. Predictions suggest that future telecommunication networks will be based on the IP Multimedia Subsystem (IMS), an all IP telecommunication core network. This paper describes an approach to combining Web 2.0 enabled applications, namely widgets, with telecommunication features using IMS. Widgets are small applications based on Web technologies that run on the client device. A new abstraction layer with interfaces for the different telecommunication features will be introduced. In addition a widget engine that makes these telecommunication interfaces available to its widgets will be presented. This will allow the rapid development of IMS applications for external developers and the combination of other Web 2.0 services with IMS features.

    Full Text Available Richard Wagner – an ihm schieden sich die Geister schon während seines Lebens. Dies geschah nicht nur in seinen deutschen Wirkungsorten, sondern auch im Südosten Europas. Schon früh fanden seine Werke auch im Banat und in Bukarest eine weite Verbreitung und das musikliebende Publikum mischte sich damals bereits in Pro- oder Kontra-Wagner-Diskussionen ein. In einem multikulturellen Raum wie das Banat, mit jahrhundertalten multiethnischen Erfahrungen und Traditionen, stieß der Wagnerkultus zuerst auf Ablehnung, später, ab 1930, wurden seine antisemitischen Anschauungen von den faschistischen Kreisen Rumäniens demagogisch missbraucht – ähnlich wie im restlichen Europa. Doch diese besondere Seite der Richard-Wagner-Rezeption hat auch eine faszinierende Auswirkung auf das allgemeine Musikleben in Rumänien und im Banat hinterlassen.

    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.

  1. Aminoglycoside resistance profile and structural architecture of the aminoglycoside acetyltransferase AAC(6')-Im.

    Aminoglycoside 6'-acetyltransferase-Im (AAC(6')-Im) is the closest monofunctional homolog of the AAC(6')-Ie acetyltransferase of the bifunctional enzyme AAC(6')-Ie/APH(2")-Ia. The AAC(6')-Im acetyltransferase confers 4- to 64-fold higher MICs to 4,6-disubstituted aminoglycosides and the 4,5-disubstituted aminoglycoside neomycin than AAC(6')-Ie, yet unlike AAC(6')-Ie, the AAC(6')-Im enzyme does not confer resistance to the atypical aminoglycoside fortimicin. The structure of the kanamycin A complex of AAC(6')-Im shows that the substrate binds in a shallow positively-charged pocket, with the N6' amino group positioned appropriately for an efficient nucleophilic attack on an acetyl-CoA cofactor. The AAC(6')-Ie enzyme binds kanamycin A in a sufficiently different manner to position the N6' group less efficiently, thereby reducing the activity of this enzyme towards the 4,6-disubstituted aminoglycosides. Conversely, docking studies with fortimicin in both acetyltransferases suggest that the atypical aminoglycoside might bind less productively in AAC(6')-Im, thus explaining the lack of resistance to this molecule.

    The characterisation of different olive oil categories (extra virgin, virgin and lampante) using Ion Mobility Spectrometry (IMS) was improved by replacing the multicapillary column (MCC) with a capillary column (CC). The data obtained with MCC-IMS and CC-IMS were evaluated, studying both the global and the specific information obtained after the analysis of the volatile fraction of olive oils. A better differentiation of the oil categories was obtained employing CC vs MCC, since the classification percentage obtained with the CC-IMS was 92% as opposed to 87% obtained with MCC-IMS; although in productivity analytical terms, MCC offer a faster analysis than GC. The specific information obtained was also used to build a database, with a view to facilitating the characterization of specific attributes of olive oils. A total of 26 volatile metabolites (aldehydes, ketones, alcohols and esters) were identified. Finally, as revealed by an ANOVA test, some volatiles differed markedly in content among the different categories of oil. The data obtained confirms the potential of IMS as a reliable analytical screening technique, which can be used to assign the correct category to an olive oil sample. Copyright © 2015 Elsevier Ltd.

    An indigenous herbal extract IM-133N containing extracts of Prosopis glandulosa Torr and Symplocos racemosa Roxb were evaluated for potential immunomodulatory effects using RAW264.7 and THP-1 cells. The incubation of the cells for 24 h with IM-133N over a dose range 0-125 µg/ml did not cause cytotoxicity that exceeded 10%. The results indicated that non-cytotoxic doses of IM-133N effectively up-regulated iNOS, TNFα, IL-6, IL-10, IL-8 and IFNγ gene expression in both the RAW264.7 and THP-1 cells. The results also indicated IM-133N elicited dose-related increases in nitric oxide (NO) and tumor necrosis factor (TNF)-α production by RAW264.7 or THP-1 cells. These results demonstrated that IM-133N could stimulate NO and induced pro-inflammatory cytokine expression by monocytes/macrophages. As clinical studies have shown IM-133N to be an effective immunomodulator without any adverse effects, the results of the present study provide further support for the potential use of this agent as an immunostimulant or as an immunotherapy adjuvant.

Participants were assigned two topics – one on each paragraph mode - from which they had to produce the two specified modes of paragraphs. The two activities occurred outside of the normal school hours for a day each. Employing a case study design and using voluntary and criterion sampling techniques, the study had four research questions, two of which were: what is the length of SMS and IM paragraphs produced by participants on the two topics they are given to write about?; and what types of textisms will participants use in their SMS and IM paragraphs, and what will be the density of such textisms? Some of the findings of the study are as follows: participants’ SMS and IM paragraphs displayed linguistic and contextual textisms, and errors in varying degrees; SMS paragraphs had more contextual textisms than IM paragraphs, while the latter had more linguistic textisms than the former; the overall textism density for both paragraph modes was lower vis-à-vis the total word count in both cases; and IM paragraphs had more compound and complex sentences than SMS paragraphs.

    Bibet-Kalinyak, Isabelle

    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.

    2017-01-01

    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.

    To better understand the role of gut microbiota in the anxiety, we isolated bifidobacteria and lactobacilli from the human faecal microbiota, investigated their inhibitory effects on the expression of interleukin (IL)-6 and tumour necrosis factor (TNF)-α in lipopolysaccharide-stimulated macrophages, and examined the anxiolytic-like effect of Bifidobacterium adolescentis IM38 in mice treated with or without immobilisation stress using the elevated plus maze (EPM) task. Oral administration of IM38 at a dose of 1×10 9 cfu/mouse showed a significant anxiolytic-like effect both in mice exposed to immobilisation stress and in control mice using the EPM test (Peffect of IM38 was comparable to that of buspirone (1 mg/kg). Moreover, this anxiolytic-like effect was blocked by treatment with flumazenil (3 mg/kg, i.p.), a benzodiazepine receptor antagonist, but was not affected by treatment with bicuculine or WAY-100635. IM38 treatment also reduced the blood levels of corticosterone and IL-6 in mice with or without immobilisation stress, whereas this effect was abolished by treatment with flumazenil. IM38 treatment also reduced the blood TNF-α level in mice subjected to immobilisation stress but not in normal control mice. Treatment with flumazenil also significantly increased TNF-α and IL-6 levels in immobilisation stress-free mice treated with IM38. These findings suggest that IM38 may attenuate anxiety through modulation of the benzodiazepine site on the GABA A receptor and modulate stress-related cytokine expression.

    Full Text Available Aktuelle Diskussionen zum studienbegleitenden Deutschunterricht verdeutlichen die Notwendigkeit danach, sich bei curricularen Überlegungen sowohl an institutionellen Rahmenbedingungen als auch an spezifischen Bedürfnissen der Studierenden zu orientieren. Da Lehrwerke den damit einhergehenden Anforderungen nach Offenheit und Adaptierbarkeit nicht gerecht werden können, sind mittelfristig alternative Konzepte gefragt, die es ermöglichen, im Zuge curricularer Überlegungen die notwendige Kohärenz zwischen einzelnen Unterrichtseinheiten herzustellen und dennoch eine flexible Anpassung an konkrete Lernkontexte zu erlauben. Der vorliegende Beitrag stellt ein solches Konzept vor. Ausgehend von der Arbeit am Tatort werden drei Lernbereiche vorgestellt, die neben der Arbeit am Film auch die Arbeit an angrenzenden Themen und Texten sowie darauf aufbauend die Entwicklung studienbegleitender kommunikativer Handlungskompetenz vorsehen.  Current discussions on teaching German alongside the core subjects at university show the necessity to consider both institutional requirements and the students' individual goals when establishing teaching objectives. Existing text books, however, suffer from an overly tight structure that doesn’t allow the instructor to use additional material in order to focus on the specific needs of the students in a suitable way. Flexible concepts are needed which serve as a framework and which can be realized with texts and tasks focusing on what is required by a specific learning context. This paper presents such an approach, using the German feature film Tatort. Besides ideas for working with the audiovisual material we will present opportunities that come along with the various texts and discussions in media and social networks arising around the film as well as ways for combining these aspects with developing language skills for the academic context.

  16. Improved detection of Mycobacterium bovis infection in bovine lymph node tissue using immunomagnetic separation (IMS-based methods.

    Directory of Open Access Journals (Sweden)

    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.

    Baber, R J; Panay, N; Fenton, A

    2016-04-01

    The International Menopause Society (IMS) has produced these new 2016 recommendations on women's midlife health and menopause hormone therapy (MHT) to help guide health-care professionals in optimizing their management of women in the menopause transition and beyond. The term MHT has been used to cover therapies including estrogens, progestogens and combined regimens. For the first time, the 2016 IMS recommendations now include grades of recommendations, levels of evidence and 'good practice points', in addition to section-specific references. Where possible, the recommendations are based on and linked to the evidence that supports them, unless good-quality evidence is absent. Particular attention has been paid to published evidence from 2013 onwards, the last time the IMS recommendations were updated. Databases have been extensively searched for relevant publications using key terms specific to each specialist area within menopause physiology and medicine. Information has also been drawn from international consensus statements published by bodies such as the IMS, the European Menopause and Andropause Society and the North American Menopause Society. The recommendations have been produced by experts derived mainly from the IMS, with the assistance of key collaborators where deemed advantageous. In preparing these international recommendations, experts have taken into account geographical variations in medical care, prevalence of diseases, and country-specific attitudes of the public, medical community and health authorities towards menopause management. The variation in availability and licensing of MHT and other products has also been considered.

  20. Predicting Optimal Resolving Power for Ambient Pressure Ion Mobility Spectrometry (IMS)

    Science.gov (United States)

    Kanu, Abu B.; Gribb, Molly M.; Hill, Herbert H

    2010-01-01

    Although diffusion theory predicts that IMS resolving power increases with the square root of the voltage applied across the drift tube, in practice there exists an optimum voltage above which resolving power decreases. This optimum voltage was determined to be both compound and initial ion pulse width-dependent. A “conditional” resolving power equation is introduced that can be used to quickly approximate realistic resolving powers for specific instrumental operating parameters and compounds. Using four common environmental contaminants [trichloroethylene (TCE), tetrachloroethylene (PCE), methyl tert-butyl ether (MTBE) and methyl iso-butyl ketone (MIBK)], diffusion-limited (theoretical), Rd, conditional, Rc, and actual (or measured), Rm, IMS resolving powers were determined and compared for a small IMS instrument designed for subsurface measurements. Detection limits determined at the optimal resolving power for the environmental contaminants ranged from 18 parts per trillion volume-to-volume (pptv) to 80 parts per billion volume-to-volume (ppbv). The maximal measured resolving power for our small, ambient-pressure stand-alone IMS ranged from 42 to 54, yielding an IMS resolving power efficiency, defined as Rm/Rc × 100%, of 56 to 74% of the maximal conditional resolving power possible.

    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.

    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.

    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).

    Matrix-assisted laser desorption/ionization time-of-flight imaging mass spectrometry (MALDI-TOF-IMS) has been a classical technique for studying proteomics in present and a tool for analyzing the distribution of proteins and small molecules within biological tissue sections. MALDI-TOF-IMS can analyze multiple unknown compounds in biological tissue sections simultaneously through a single measurement which can obtain molecule imaging of the tissue while maintaining the integrity of cellular and molecules in tissue. In recent years, imaging mass spectrometry technique develops relatively quickly in all biomedical domain. This paper based on the relevant data and reviews the present developing level of MALDI-TOF-IMS, the principle of imaging mass spectrometry, methology and the prospect in forensic pathology.

    The noble gas component of the International Monitoring System (IMS) is supposed to detect radioxenon fission products from nuclear explosions and thereby deliver proof of the nuclear character of suspicious events. In this work an approach is presented to determine the network coverage of the IMS {sup 133}Xe component. Various parameters that influence the network coverage are identified and included. The global radioxenon background from legitimate facilities has been simulated and the resulting impact on the IMS noble gas component calculated. From this background a station-specific detection criterion has been deducted. Furthermore, emissions from underground as well as surface test explosions of 1kt devices have been simulated for each grid point and time step of one year. The percentage of detectable nuclear explosions has been calculated and analysed for geographical and temporal variances.

    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.

  13. Nanomaterial size distribution analysis via liquid nebulization coupled with ion mobility spectrometry (LN-IMS).

    Science.gov (United States)

    Jeon, Seongho; Oberreit, Derek R; Van Schooneveld, Gary; Hogan, Christopher J

    2016-02-21

    We apply liquid nebulization (LN) in series with ion mobility spectrometry (IMS, using a differential mobility analyzer coupled to a condensation particle counter) to measure the size distribution functions (the number concentration per unit log diameter) of gold nanospheres in the 5-30 nm range, 70 nm × 11.7 nm gold nanorods, and albumin proteins originally in aqueous suspensions. In prior studies, IMS measurements have only been carried out for colloidal nanoparticles in this size range using electrosprays for aerosolization, as traditional nebulizers produce supermicrometer droplets which leave residue particles from non-volatile species. Residue particles mask the size distribution of the particles of interest. Uniquely, the LN employed in this study uses both online dilution (with dilution factors of up to 10(4)) with ultra-high purity water and a ball-impactor to remove droplets larger than 500 nm in diameter. This combination enables hydrosol-to-aerosol conversion preserving the size and morphology of particles, and also enables higher non-volatile residue tolerance than electrospray based aerosolization. Through LN-IMS measurements we show that the size distribution functions of narrowly distributed but similarly sized particles can be distinguished from one another, which is not possible with Nanoparticle Tracking Analysis in the sub-30 nm size range. Through comparison to electron microscopy measurements, we find that the size distribution functions inferred via LN-IMS measurements correspond to the particle sizes coated by surfactants, i.e. as they persist in colloidal suspensions. Finally, we show that the gas phase particle concentrations inferred from IMS size distribution functions are functions of only of the liquid phase particle concentration, and are independent of particle size, shape, and chemical composition. Therefore LN-IMS enables characterization of the size, yield, and polydispersity of sub-30 nm particles.

    A high-throughput approach and platform using 15 minute reversed-phase capillary liquid chromatography (RPLC) separations in conjunction with ion mobility spectrometry-mass spectrometry (IMS-MS) measurements was evaluated for the rapid analysis of complex proteomics samples. To test the separation quality of the short LC gradient, a sample was prepared by spiking twenty reference peptides at varying concentrations from 1 ng/mL to 10 µg/mL into a tryptic digest of mouse blood plasma and analyzed with both a LC-Linear Ion Trap Fourier Transform (FT) MS and LC-IMS-TOF MS. The LC-FT MS detected thirteen out of the twenty spiked peptides that had concentrations ≥100 ng/mL. In contrast, the drift time selected mass spectra from the LC-IMS-TOF MS analyses yielded identifications for nineteen of the twenty peptides with all spiking levels present. The greater dynamic range of the LC-IMS-TOF MS system could be attributed to two factors. First, the LC-IMS-TOF MS system enabled drift time separation of the low concentration spiked peptides from the high concentration mouse peptide matrix components, reducing signal interference and background, and allowing species to be resolved that would otherwise be obscured by other components. Second, the automatic gain control (AGC) in the linear ion trap of the hybrid FT MS instrument limits the number of ions that are accumulated to reduce space charge effects and achieve high measurement accuracy, but in turn limits the achievable dynamic range compared to the IMS-TOF instrument.

    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.

    Homogene selbstzündende Brennverfahren werden schon seit den 70er Jahren im ottomotorischen Bereich untersucht. Durch die zunehmende Verschärfung der Abgasgesetzgebung stehen seit Mitte der 90er Jahre auch verstärkt homogene Brennverfahren mit Dieselkraftstoff (HCCI-Verfahren) im Fokus der Forschung. Das große Interesse begründet sich in einer annähernd verbrauchsneutralen Reduzierung von sowohl Partikel als auch Stickoxid-Emissionen und damit in der innermotorischen Auflösung des Ruß-NOX Tra...

  19. Datamart use for complex data retrieval in an ArcIMS application

    Energy Technology Data Exchange (ETDEWEB)

    Scherma, S. (Steven); Bolivar, Stephen L.

    2004-01-01

    This paper describes the use of datamarts and data warehousing concepts to expedite retrieval and display of complex attribute data from multi-million record databases. Los Alamos National Laboratory has developed an Internet application (SMART) using ArcIMS that relies on datamarts to quickly retrieve attribute data, associated with, but not contained within GIS layers. The volume of data and the complex relationships within the transactional database made data display within ArcIMS impractical without the use of datamarts. The technical issues and solutions involved in the development are discussed.

    Bernhard, Werner; Keller, Thomas; Regenscheit, Priska

    1995-01-01

    The IMS (Ion Mobility Spectroscopy) instrument 'Ionscan' takes advantage of the fact that trace quantities of illicit drugs are adsorbed on dust particles on clothes, in cars and on other items of evidence. The dust particles are collected on a membrane filter by a special attachment on a vacuum cleaner. The sample is then directly inserted into the spectrometer and can be analyzed immediately. We show casework applications of a forensic chemistry and toxicology laboratory. One new application of IMS in forensic chemistry is the detection of psilocybin in dried mushrooms without any further sample preparation.

    The role of endovascular therapy in patients with acute ischemic stroke and a solitary M2 occlusion remains unclear. Through a pooled analysis of 3 interventional stroke trials, the authors sought to analyze the impact of successful early reperfusion of M2 occlusions on patient outcome. Patients with a solitary M2 occlusion were identified from the Prolyse in Acute Cerebral Thromboembolism (PROACT) II, Interventional Management of Stroke (IMS), and IMS II trial databases and were divided into 2 groups: successful reperfusion (thrombolysis in cerebral infarction [TICI] 2-3) at 2 hours and failed reperfusion (TICI 0-1) at 2 hours. Baseline characteristics and clinical outcomes were compared. Sixty-three patients, 40 from PROACT II and 23 from IMS and IMS II, were identified. Successful early angiographic reperfusion (TICI 2-3) was observed in 31 patients (49.2%). No statistically significant difference in the rates of intracerebral hemorrhage (60.9% vs 47.6%, p = 0.55) or mortality (19.4% vs 15.6%, p = 0.75) was observed. However, there was a trend toward higher incidence of symptomatic hemorrhage in the TICI 2-3 group (17.4% vs 0%, p = 0.11). There was also a trend toward higher baseline glucose levels in this group (151.5 mg/dl vs 129.6 mg/ dl, p = 0.09). Despite these differences, the rate of functional independence (modified Rankin Scale Score 0-2) at 3 months was similar (TICI 2-3, 58.1% vs TICI 0-1, 53.1%; p = 0.80). A positive correlation between successful early reperfusion and clinical outcome could not be demonstrated for patients with M2 occlusion. Irrespective of reperfusion status, such patients have better outcomes than those with more proximal occlusions, with more than 50% achieving functional independence at 3 months.

    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.

    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.

    Full Text Available An IMS Learning Design Expert Workshop was held at the University of Vienna on November 20 & 21, 2008. This report contains a description of the purpose of the workshop, its methodologies and results. Participating experts first brainstormed visions and problems of IMS Learning Design (IMS LD, and then developed potential solutions to some of the identified problems. Three groups formed to work on two of the identified problems in more depth: the usability and utility problem, and the life cycle of a unit of learning problem. The proposed solutions regarding the usability and utility problem were to investigate how teachers' and learners' representations of a learning design can be brought together, and to set up a research program to identify how teachers cognitively proceed when designing courses and to map this knowledge to IMS LD. In regard to the life cycle of a unit of learning problem, the group suggested a system that continually exchanges information between runtime and editing systems so that units of learning can be updated accordingly.

    The Multi-Angle Imager for Aerosols (MAIA) instrument, which was recently selected under NASA's third Earth Venture Instrument call, will improve aerosol particle type sensitivity through the atmospheric column as well as at the surface through the use of multiangular, multispectral, and polarimetric observations. MAIA will provide new information that enables estimates of speciated (size- and particle type classifications) surface particulate matter (PM) from space over major cities around the globe, and enable improved associations between particulate air pollution and human health. As a pathfinder to MAIA, the ImPACT-PM field campaign was a joint JPL/Caltech effort to combine measurements from MISR and AirMSPI with in situ airborne measurements and a chemical transport model to validate remote sensing retrievals of different types of airborne particulate matter. We will present highlights of the successfully completed ImPACT-PM field campaign which took place in the California Central Valley on July 5-8, 2016. We had two NASA ER-2/ CIRPAS Twin Otter collocated flights coincident with Terra/MISR overpasses on Tuesday and Thursday July 5 and 7; and two ER-2/Twin Otter collocations over local fires on Friday, July 8th. The AirMSPI, AirSPEX, and CPL instruments were integrated on the ER-2, and Caltech aerosol/cloud in-situ instruments were integrated on the CIRPAS Twin Otter aircraft in addition to the normal Twin Otter payload. We also deployed the JPL/University of Arizona GroundMSPI instrument and a ground-based lidar from San José State University at the Fresno California Air Resources Board super-site. While the overall aerosol and PM levels were low at this time, we were able to see a gradient of pollution in specially processed MISR high-resolution 4.4 km resolution aerosol data on both days. We will present initial results of AirMSPI WRF-Chem-constrained retrievals in comparison with EPA Speciation Trends Network stations in Fresno and Bakersfield, and with

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

    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.

    A high-throughput approach and platform using 15 minute reversed-phase capillary liquid chromatography (RPLC) separations in conjunction with ion mobility spectrometry-mass spectrometry (IMS-MS) measurements was evaluated for the rapid analysis of complex proteomics samples. To test the separation quality of the short LC gradient, a sample was prepared by spiking twenty reference peptides at varying concentrations from 1 ng/mL to 10 µg/mL into a tryptic digest of mouse blood plasma and analyzed with both a LC-Linear Ion Trap Fourier Transform (FT) MS and LC-IMS-TOF MS. The LC-FT MS detected thirteen out of the twenty spiked peptides that had concentrations ≥100 ng/mL. In contrast, the drift time selected mass spectra from the LC-IMS-TOF MS analyses yielded identifications for nineteen of the twenty peptides with all spiking level present. The greater dynamic range of the LC-IMS-TOF MS system could be attributed to two factors. First, the LC-IMS-TOF MS system enabled drift time separation of the low concentration spiked peptides from the high concentration mouse peptide matrix components, reducing signal interference and background, and allowing species to be resolved that would otherwise be obscured by other components. Second, the automatic gain control (AGC) in the linear ion trap of the hybrid FT MS instrument limits the number of ions that are accumulated to reduce space charge effects, but in turn limits the achievable dynamic range compared to the TOF detector.

    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

  8. Interfacility transports.

    Science.gov (United States)

    Blackwell, Thomas H

    2002-02-01

    Financial pressures exerted by managed care organizations toward hospitals to improve efficiencies and to lower total healthcare costs continue to force physicians and administrators to reevaluate operations and practices. This shifting of risk exposure from insurers to providers has resulted in many mergers, acquisitions, and affiliations, so as to form integrated health systems that reduce repetition and duplication of services. Therefore, as these integrated systems develop, along with the emergence of tertiary care, regional referral, and specialty hospitals, the need for patient transfers between such facilities will expand. The decision to move patients between facilities is a multicomponent process comprising health, safety, financial, and legal concerns. Interfacility transportation of patients has been performed over the past 20 to 30 years. Whereas ground transport services were prominent in the 1970s, air medical programs using helicopters and fixed-wing aircraft have recently become widespread. Both hospital-based and private agencies have continued to develop programs for efficiently and expeditiously transporting critically ill or injured patients, many requiring complex life-support devices. The Practice Management Committee of the American College of Emergency Physicians recently updated the 1990 policy statement on interfacility transfers, and two position statements are available from the National Association of EMS Physicians on criteria for air medical transport and medical direction for interfacility transport services. This review provides an overview of transportation systems and services available and assists physicians in understanding the various modes and characteristics of systems available. Personnel configurations and capabilities, physiological limitations, inherent requirements for equipment and patient preparation, and legal issues involved with transferring patients are also outlined.

    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.

Finansallaşma sürecinde bu temas, iletişim politikaları vasıtasıyla sağlanır; ekonomi-politika ve bundan sorumlu merkezi kurumlarla toplumsal alan arasındaki bağ, iletişim stratejileri üzerinden kurulur; ekonomik alan ile kültürel alan arasındaki boşluk, iletişim kanalları içerisinden taşınan enformasyon marifetiyle doldurulur; insana ilişkin öngörülemezlikler, iletişim süreçleri vasıtasıyla öngörülebilir kılınır. Bu çalışmada, iletişim çalışmaları içerisinde yeni bir mecra olarak çağrılan “finansal iletişim”in farklı temas noktalarına işaret edilecek ve her bir uğrağın finansal iletişim alanına bağlandığı nokta, modeller üzerinden gösterilecektir.

    NASA and ESA are now planning a reduced version of the joint Europa Jupiter System Mission (EJSM), potentially including a radically descoped Jupiter Europa Orbiter (JEO) but still with magnetometer and plasma instruments. Similar field and plasma instrumentation would also reside on ESA's Jupiter Ganymede Orbiter (JGO), which conceivably could carry out multiple flybys of Europa before entering orbit at Ganymede. We are developing the 3D Ion Mass Spectrometer (IMS) designed to measure both major and minor ion species within the high radiation environment of Jupiter s magnetosphere and the icy Galilean moons. The IMS covers the energy range from 10 eV to 30 keV, wide field-ofview (FOV) capability and 10-60 sec time resolution for major ions. This instrument has two main goals: 1) measure the plasma interaction between Europa and Jupiter s magnetosphere and 2) infer the global surface composition to trace elemental and significant isotopic levels; these goals are also applicable for in-situ measurements at Ganymede and Callisto, and remotely everywhere via the iogenic plasma for Io. The first goal supports the magnetometer (MAG) measurements, primarily directed at detection of Europa's sub-surface ocean, while the second goal gives information about transfer of material between the Galilean moons, e.g. mainly from Io to the other moons, and further allows detection of oceanic materials emergent to the moon surfaces from subsurface layers putatively including salt water oceans. Outgassed exospheric materials are probed by the IMS by measuring pickup ions accelerated up to spacecraft altitudes of approximately 100-200 km in electric fields extending through the local magnetospheric environment and moon exosphere to the surface. Our 3D hybrid kinetic model of the moon-magnetosphere interaction is used to construct a global model of electric and magnetic fields for tracing of pickup ion trajectories back to the sources at approximate surface resolution of 100 km.

    Full Text Available The purpose of this paper is to contribute to learning, knowledge creation and knowledge transfer for building organization innovability by integrating the management systems in the SIMPRO-IMS web based environment. The paper content consists of the interpretation of role-play simulation, role-play simulation process description, methodology, and the employment of role-play simulation outcomes, as well as the discussion of the knowledge thus obtained. Primary the model of the SIMPRO-Q education environment has been developed and tested during a period of 15 years in several industrial organizations as well as service organizations such as Higher Education Institution (HEI and Healthcare Organization (HCO. 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

    While studies that have examined the prevalence of musculoskeletal injuries in alpine skiing and snowboarding exist, there has been no discussion of how neurocognitive deficits may influence such injuries. Recent authors have identified a possible link between Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) testing results and the prevalence of musculoskeletal injury in athletic populations. However, no study has specifically examined this in the alpine skiing and snowboard athletes who sustain injury and those that do not. The purpose was to review injury data and ImPACT test results within the local ski/snowboard population to determine if there was a difference in components of ImPACT test scores between injured and non-injured athletes. It was hypothesized that differences would exist in component scores on ImPACT testing between injured and non-injured athletes. Retrospective cohort study. Injury records and baseline ImPACT testing scores for 93 athletes aged 14-17 participating in a local ski and snowboard club during the 2009-2012 seasons were gathered retrospectively. Injuries documented for the lower and upper extremity included ligament sprains, muscle strains, contusions, dislocation/subluxation, fractures and concussions. Athletes who sustained any of these listed injuries were categorized within the injured athlete group. Each component of ImPACT test scores was compared between gender and for injury status within skiing and snowboarding disciplines using a series of two-way analysis of variance tests. There was no difference between non-injured and injured females as well as non-injured and injured males in reaction time and visual motor speed (VMS), however there was an interaction between gender and injury status on composite reaction time and visual motor speed, or VMS. The composite reaction time for females was 4.7% faster with injury while males without injury had a composite reaction time that was slower by 5.8%. Females had

Bei dem Projekt handelt es sich um den ersten umfassenden Versuch einer filmischen Reflexion über den Faschismus und implizit auch über die eigene totalitäre Vergangenheit in der nachstalinistischen Sowjetunion. Dieser Schlüsselfilm der 1960er Jahre löste eine breite internationale Diskussion aus, die Einblick in das diskursive Feld der wechselseitigen politisch-ideologischen Spiegelungen während der Zeit des Kalten Krieges gewährt. Obyknovennyi fashizm gehört zum Genre des „Kompilationsfilms“, das eine Wiederveröffentlichung und Neuinterpretation historischen Bildmaterials leistet. Montiert wurde der Film aus NS-Wochenschauen, Dokumentarfilmen und Kulturfilmen (2 Mio Meter Film, die 1945 von der Roten Armee aus den Beständen des Reichsfilmarchivs konfisziert und nach Moskau gebracht worden waren. Dieses Filmmaterial wurde ergänzt durch Fotografien, etwa die Fotoporträts des Hitler-Leibfotografen Heinrich Hoffmann oder private Schnappschüsse von Soldaten der deutschen Wehrmacht, die Jahrzehnte später im Zusammenhang mit der ersten Wehrmachtsausstellung großes Aufsehen erregten. In dem Artikel von Wolfgang Beilenhoff und Sabine Hänsgen werden die langwierige Produktionsgeschichte und die kontroverse Rezeption des Films in BRD und DDR behandelt.

  9. The Lack of the Essential LptC Protein in the Trans-Envelope Lipopolysaccharide Transport Machine Is Circumvented by Suppressor Mutations in LptF, an Inner Membrane Component of the Escherichia coli Transporter

    KAUST Repository

    Benedet, Mattia

    2016-08-16

    The lipopolysaccharide (LPS) transport (Lpt) system is responsible for transferring LPS from the periplasmic surface of the inner membrane (IM) to the outer leaflet of the outer membrane (OM), where it plays a crucial role in OM selective permeability. In E. coli seven essential proteins are assembled in an Lpt trans-envelope complex, which is conserved in gamma-Proteobacteria. LptBFG constitute the IMABC transporter, LptDE form the OM translocon for final LPS delivery, whereas LptC, an IM-anchored protein with a periplasmic domain, interacts with the IM ABC transporter, the periplasmic protein LptA, and LPS. Although essential, LptC can tolerate several mutations and its role in LPS transport is unclear. To get insights into the functional role of LptC in the Lpt machine we searched for viable mutants lacking LptC by applying a strong double selection for lptC deletion mutants. Genome sequencing of viable Delta lptC mutants revealed single amino acid substitutions at a unique position in the predicted large periplasmic domain of the IM component LptF (LptF(SupC)). In complementation tests, lptF(SupC) mutants suppress lethality of both Delta lptC and lptC conditional expressionmutants. Our data show that mutations in a specific residue of the predicted LptF periplasmic domain can compensate the lack of the essential protein LptC, implicate such LptF domain in the formation of the periplasmic bridge between the IM and OM complexes, and suggest that LptC may have evolved to improve the performance of an ancestral six-component Lpt machine.

    In adult humans, the net absorption of dietary copper is approximately 1 mg/d. Dietary copper joins some 4-5 mg of endogenous copper flowing into the gastrointestinal tract through various digestive juices. Most of this copper returns to the circulation and to the tissues (including liver) that formed them. Much lower amounts of copper flow into and out of other major parts of the body (including heart, skeletal muscle, and brain). Newly absorbed copper is transported to body tissues in two phases, borne primarily by plasma protein carriers (albumin, transcuprein, and ceruloplasmin). In the first phase, copper goes from the intestine to the liver and kidney; in the second phase, copper usually goes from the liver (and perhaps also the kidney) to other organs. Ceruloplasmin plays a role in this second phase. Alternatively, liver copper can also exit via the bile, and in a form that is less easily reabsorbed. Copper is also present in and transported by other body fluids, including those bathing the brain and central nervous system and surrounding the fetus in the amniotic sac. Ceruloplasmin is present in these fluids and may also be involved in copper transport there. The concentrations of copper and ceruloplasmin in milk vary with lactational stage. Parallel changes occur in ceruloplasmin messenger RNA expression in the mammary gland (as determined in pigs). Copper in milk ceruloplasmin appears to be particularly available for absorption, at least in rats.

    Ion mobility spectrometers (IMS) are highly sensitive instruments for monitoring airborne pollution. Portable types with low mass are commercially available already, but the cost so far has been too high for general acceptance. It was investigated how alternative microsystem technologies may make construction and production more efficient. The standard quality parameters of the system were reached. The following key modules were investigated: Sensor (drift cell in particular), inlet, power supply, and microprocessor. Further investigations of potential influencing parameters or system parameters were necessary in order to make the system reproducible. Prototypes were constructed and tested using different technologies. (orig.) [German] Ionenmobilitaetsspektrometer (IMS) stellen hochempfindliche Messgeraete fuer Verunreinigungen in der Luft dar.

    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.

    Full Text Available In diesem Beitrag wird Globalisierung als Prozess der Umstellung von Bezugssystemen des Denkens und Handelns von "Staat" auf "Welt" konzipiert. Von der klassischen Definition des Nationalstaates ausgehend, werden zuerst drei staatszentrierte Bezugssysteme (Rechtsstaat, Sozialstaat, Territorialstaat skizziert. Im zweiten Schritt werden globale Bezugssysteme (Welt als einheitlicher Markt, als Gefüge von Herrschaftsgebilden, als Konglomerat von Kulturen umrissen. Die Argumentation läuft darauf hinaus, zu zeigen, dass es sich bei diesen Konzeptionen keineswegs um geschlossene und harmonische Gesellschafts- und Weltbilder handelt; vielmehr enthält jedes der sechs Bezugsysteme spezifische Spannungs- und Konfliktlinien, aus denen sich ihre jeweilige Dynamik speist. Im dritten Schritt werden Prozesse der Umstellung der Bezugssysteme in Richtung Globalität auf drei Ebenen analysiert: auf der Ebene umfassender historischer Prozesse, auf der Ebene staatlichen Handelns und auf der Ebene individueller Akteure.

    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.

    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.

    In this paper, an ion source based on wire-to-plate corona is developed for Ion Mobility Spectrometer (IMS). The characteristics of the corona discharge and the ion current detected on Faraday plate are investigated under different electrode spacing and voltage. The effect of voltage polarity is also studied. The features of this new designed ion source are compared with that of point-to-plate corona. The results show that the present IMS prototype machine can provide a much larger value of ion current connected by Faraday plate than the point-to-plate corona and/or the traditional 63Ni source. The corona configuration can also act as a good electromagnetic shielding to defense the electromagnetic emission from the corona discharge.

    SIMS is applied to a wide variety of applications in geosciences, as it offers both sensitivity and in situ isotopic and/or elemental analysis of solid samples. CAMECA has introduced the IMS 7f-GEO, a compact SIMS model designed to meet the high precision/high throughput requirements of stable isotope and trace element analysis. For high precision/high throughput measurements, the detectors choice is the first issue to consider. It is well known that Faraday Cups (FCs) are preferred to Electron Multipliers (EMs) provided the secondary ion intensities are high enough. Secondly, in the absence of parallel detection, it is crucial to perform the switching between the different species as fast as possible, and to monitor all relevant parameters that may compromise the achievable precision. The IMS 7f-GEO has been designed to meet these instrumental performance requirements.

    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.
