    The NGC 1999 reflection nebula features a dark patch with a size of 10 000 AU, which has been interpreted as a small, dense foreground globule and possible site of imminent star formation. We present Herschel PACS far-infrared 70 and 160 μm maps, which reveal a flux deficit at the location of the globule. We estimate the globule mass needed to produce such an absorption feature to be a few tenths to a few {M}⊙. Inspired by this Herschel observation, we obtained APEX LABOCA and SABOCA submillimeter continuum maps, and Magellan PANIC near-infrared images of the region. We do not detect a submillimer source at the location of the Herschel flux decrement; furthermore our observations place an upper limit on the mass of the globule of 2.4×10-2 {M}⊙. Indeed, the submillimeter maps appear to show a flux depression as well. Furthermore, the near-infrared images detect faint background stars that are less affected by extinction inside the dark patch than in its surroundings. We suggest that the dark patch is in fact a hole or cavity in the material producing the NGC 1999 reflection nebula, excavated by protostellar jets from the V 380 Ori multiple system.

    Full Text Available Evelyn Zegenhagen hat ohne Zweifel das am besten recherchierte Buch über die Geschichte des Frauenfliegens und über die Rolle der Pilotinnen in der Geschichte der Luftfahrt zwischen 1918 und 1945 vorgelegt. Mit einem unglaublichen Forschungsaufwand hat sie viele Lücken in der vorliegenden Forschung zu diesem Thema geschlossen und erstmalig Biographien von Segelfliegerinnen und deren Chancen und Probleme aufgearbeitet. Damit gewährt sie Einblicke in einen Bereich der Luftfahrtgeschichte, der neue Perspektiven, nicht nur im Hinblick auf die Beteiligung von Frauen, eröffnet. Umfangreiche Quellenstudien ermöglichten es zudem, die Lebensläufe bisher weitgehend unbekannter Fliegerinnen zu rekonstruieren und bereits bekannte und gut dokumentierte Biographien um neue Facetten zu ergänzen. Zegenhagen hat den Anspruch, die Fliegerei der Frauen im zeitgenössischen Kontext zu betrachten und neben den individuellen Chancen auch die strukturellen Bedingungen zu berücksichtigen, ohne Frage eingelöst.

    Measurements have been made of the astronomical tide in Loch Ness, Scotland, which is not directly connected to marine tides. Our measurements of the loch tide are, so far as we know, the first in a European lake where the tide originates primarily from ocean tide loading. Loch Ness is a readily accessible lake and is in a region for which the neighboring ocean tides are large and described well by modern global ocean tide models. The principal tidal constituent, M2, was observed to have an amplitude of approximately 1.5 mm, and to be in antiphase, at each end of the loch. These values are in close agreement with the theoretical combined effects of the direct gravitational tide (body tide) and the tilt effects due to ocean tide loading, computed using Green's functions based on conventional elastic-Earth models. By analyzing over long periods for coherent tidal signals, we are able to significantly improve the signal-to-noise ratio in the tilt values compared with values obtained by direct level differencing. Our tilt accuracy of better than 10-8, measured over 35 km, demonstrates Loch Ness as one the world's longest and most accurate tiltmeters. Despite this unprecedented accuracy, Earth tidal models are still at least as accurate as our ability to measure them.

    We classify Veech groups of tame non-compact flat surfaces. In particular we prove that all countable subgroups of $\\mathbf{GL}_+(2,\\R)$ avoiding the set of mappings of norm less than 1 appear as Veech groups of tame non-compact flat surfaces which are Loch Ness monsters. Conversely, a Veech group of any tame flat surface is either countable, or one of three specific types.

  8. The Difficulty of Saying "I": Translation and Censorship of Christa Wolf's Der geteilte Himmel

    Full Text Available The end of the GDR in 1990 triggered a vivid literary debate in Germany which focused on the interrelationship of politics, literature, and criticism. In this context, the work of Christa Wolf was attacked as primary example of self-censorship and collaboration. In my article, I argue that Wolf became the target of literary criticism largely because of her attempt to express female subjectivity in her texts. In my contrastive analysis of Der geteilte Himmel (1963 and its English translation (1965, I read Wolf's text as an initial attempt at a "socialist modernism." The continued value of this and subsequent works by Wolf lies in the accuracy and complexity with which she probes human behavior under adverse historical circumstances. Even a text like Der geteilte Himmel , which on a surface level reads merely like a political vote for socialism in the GDR as well as the writer's support for the division of Germany, eludes the binary opposition of East/West, them/us that critics have used to categorize Wolf's work. The hybrid nature of the text serves as example of Wolf's sincerity as a writer, evidence of her personal integrity, as well as her relentless commitment to a social alternative.

  9. Using Loch Ness to track the tilt of the world

    2012-01-01

    That the rise and fall of the tide is driven primarily by the gravitational pull of the Moon and the Sun is common knowledge, but not all tides are controlled by such a standard mechanism. Researchers working on Loch Ness in Scotland found that rather than the loch's tide being driven directly by this so-called astronomical tide, it is also controlled by a process known as ocean tidal loading. Loch Ness lies just 13 kilometers inshore from the North Sea. The astronomical tide redistributes the ocean to such an extent that the changing mass of water along the coast deforms the seafloor. As the ocean tide ebbs and flows, the surface of the Earth rises and falls.

Indeed, several Chilean educators were to his PhD to United States of America in these areas; among them are Mario Leyton and Erika Himmel, who specialized in curriculum and evaluation, through the approaches of Tyler and Bloom. Therefore, both were actively involved in the introduction into the country of two measurement systems: (1 selection for admission to the University, creating a standardized test, the academic aptitude test –paa– which was established from 1967 and remained until 2002 and from 2003 to date was changed to the university selection test –psu–; initially the paa contained only verbal and mathematical aptitude tests; knowledge tests were subsequently added specific (in mathematics, biology, physics, chemistry and Sciences social. (2 the measurement of achievements educational system school, both in basic education and medium from the 1970s with the called initially program of evaluation of educational achievement –per– and, subsequently, with the system of measurement of the quality of the teaching –simce–, which applies from 1988 until today, at the national level and at various levels of the school system: 4.° Basic, 8.° Basic and 2.° Medium, especially with tests of language and communication and mathematics. Both initiatives were directly involved Mario Leyton and Erika Himmel; the first to key positions in the Ministry of Education and the second as academic of the University of Chile and the Catholic University of Chile.

    Coastal oceans are sites of biogeochemical cycling, as terrestrial, atmospheric, and marine carbon cycles interact. Important processes that affect the carbon cycle in the coastal ocean include upwelling, river input, air-sea gas exchange, primary production, respiration, sediment burial, export, and sea-ice dynamics. The magnitude and variability of many carbon fluxes are accordingly much higher in coastal oceans than in open ocean environments. Having high-quality observations of carbon stocks and fluxes in the coastal environment is important both for understanding coastal ocean carbon balance and for reconciling continent-scale carbon budgets. Despite the ecological, biological, and economic importance of coastal oceans, the magnitude and variability of many of the coastal carbon stocks are poorly quantified in most regions in comparison to terrestrial and deep ocean carbon stocks. The first stage in understanding the carbon dynamics in coastal waters is to quantify the existing carbon stocks. The coastal sediment potentially holds a significant volume of carbon; yet there has been no comprehensive attempt to quantitatively determine the volume of carbon held in those coastal sediments as echoed by Bauer et al., (2013) "the diverse sources and sinks of carbon and their complex interactions in these waters remain poorly understood". We set out to create the first sedimentary carbon inventory for a sea loch (fjord); through a combination of geophysics and biogeochemistry. Two key questions must be answered to achieve this goal; how much sediment is held within the loch and what percentage of that sediment carbon? The restrictive geomorphology of sea lochs (fjords) provides the perfect area to develop this methodology and answer these fundamental questions. Loch Sunart the longest of the Scottish sea lochs is our initial test site due to existing geophysical data being available for analysis. Here we discuss the development of the joint geophysics and

    Movements of adult Atlantic salmon were determined as they migrated through Loch Faskally, a 4-km long hydroelectric reservoir in North-east Scotland. The horizontal and vertical movements of four salmon were monitored for periods of 4-7 days using depth-sensing acoustic transmitters in June-July 1995. Each fish began sustained directed upstream movements within 5.5 h after release at swimming speeds of 0.15-0.40 bl s -1 . Three fish reached the head of the loch after 7.25-17 h, but then returned downstream. The four fish remained in the upper half of the loch for 15-51 days, making localized movements. Mean depths of fish were 3.7-4.0 m (max 20.7 m). Two fish were recorded at significantly shallower depths at night during the day. Departure from the loch coincided with periods of high water flow into the reservoir. In May-July 1996, 17 radio-tagged salmon entered Loch Faskally and reached the head of the loch in 3 h-5.8 days (mean 39 h). The durations of stay in the loch varied from 3 h 50 min to 67.4 days (mean 10.9 days). Only two radio-tagged salmon left the loch under conditions of high water flow into the loch. (author)

    The majority of pacemaker pocket or lead erosions are due to either mechanical erosion by the bulky pulse generator or secondary to pacemaker pocket infection. We describe an unusual case of delayed pacemaker lead erosion causing extrusion of a portion of the pacing lead, with separate entry and exit points, with the gap filled with new skin formation, simulating the "Loch Ness Monster", which was successfully managed conservatively by surgical reinsertion.

  14. Scottish Sea Lochs: High Resolution Archives of North Atlantic Climate

    The sea lochs (fjords) of NW Scotland bridge the land-ocean interface in a region of Europe which is particularly well situated to monitor changes in westerly air flow. Inter-annual atmospheric circulation changes at this latitude are largely governed by the North Atlantic Oscillation (NAO), in turn influencing both westerlies and precipitation. Comparing two extreme recent NAO years, circulation modelling results from Loch Sunart, NW Scotland, reveal a clear response to freshwater runoff and wind forcing in both magnitude and rate of deep-water renewal events. Scottish fjords, because of the relatively small impact which salinity has on d18Owater (0.18 % per salinity unit), potentially provide NW Europe's most useful study sites in coastal palaeoclimate research, particularly where palaeotemperature is the primary record of interest. New data from a high-resolution record (7 yr sample resolution), spanning the last two millennia, from the deepest part of the main basin of Loch Sunart illustrate significant multi-decadal to centennial scale variability in the sedimentary and stable isotope record of epibenthic foraminifera Cibicides lobatulus. The long-term pattern in benthic d18O appears to reflect bottom water temperature differences of 1-2§C, resolving climatic periods such as the Medieval Warm Period and the Little Ice Age. Since the core site is connected with shelf waters (i.e. no shallow sill) it seems likely that this paleotemperature reflects changing shelf water, not the exchange process as a function of long-term runoff/wind forcing. Grain size data and XRF data point to catchment-wide responses (weathering and erosion) which appear to show the largest variability during the last millennium, driven either by rainfall and temperature and/or land-use. Pb-isotope data, constraining the modern and industrial period, suggest accelerated sedimentation rates over this interval. On-going work attempts to calibrate proxy data with instrumental historical data.

  16. Sources and fluxes of inorganic carbon in a deep, oligotrophic lake (Loch Ness, Scotland)

    Science.gov (United States)

    Jones, R. I.; Grey, J.; Quarmby, Christopher; Sleep, Darren

    2001-12-01

    The main river inflows to Loch Ness and several depths in the water column within the loch were sampled over an annual cycle. The carbon isotope composition of total dissolved inorganic carbon (DIC) from the samples was determined as well as that of phytoplankton from the loch. Values of δ13C for DIC in the rivers indicated that this DIC was derived from soil respiration in the catchment and achieved only partial equilibrium with the atmosphere during river transport. Riverine loading accounted for most of the DIC in Loch Ness, and the great depth of the loch relative to its surface area allows only limited exchange with the atmosphere. Despite the low productivity in Loch Ness, DIC concentrations in the low alkalinity water are appreciably influenced by plankton metabolism, and seasonal fluctuations in δ13C of DIC and phytoplankton revealed the particular impact of photosynthetic carbon fixation on DIC. However, the photosynthetic depletion of DIC during summer does not offset the riverine loading sufficiently to prevent the loch waters being supersaturated with CO2 throughout the year. Annual efflux of CO2 from Loch Ness is estimated to be 253 × 106 mol yr-1, of which around one quarter may be due to net heterotrophic mineralization within the loch of organic carbon of terrestrial origin. The remainder is attributable to inorganic carbon input to the lake via river inflow and derived from prior mineralization of soil organic matter within the drainage area. This annual efflux of CO2 can represent around 6% of net ecosystem production in the catchment.

    Full Text Available This paper elaborates a theme at the interface between linguistics and literature on the case example of a novel which belongs to the immigrant literature as part of the contemporary Austrian literature. The Croatian author Ana Bilic describes in her first novel written in German language Das kleine Stück vom großen Himmel (The small part of the big sky published in 2002 the love relationship between a Croatian unnamed female student and the Austrian student Ernst which takes place in Vienna. The unusual thing in this novel is the fact that in numerous sentences and passages the author uses a strange German language which is characterized by interference mistakes, or to be precise a Croatian-German language variation which more or less differs grammatically and lexically from standard German language. In the paper this consciously alienated language is being investigated concerning the influence of the Croatian mother tongue of the author, but also concerning common mistakes while learning German language. The paper also analyses the motivation of Ana Bilic for such in the context of immigrant literature unusual language use, which is also connected with the plot of the novel. Thus qualitative as well as quantitative methods of analysis are being used, whereby the former ones refer to the content and the latter ones to the frequency of interference mistakes in the book. The interference mistakes belong on one side to the fictional (text-internal world and on the other side to the factual (text-external level, because they reflect the plot of the book and establish on the level of content and language a connection between the first-person narrator and the author, who also had to learn German after her arrival to Vienna. As a result of this most interference mistakes appear in the first chapters of the novel, which reflects the first phase in German language learning of the female narrator. Further on in the novel the quantity of the mistakes

    The Water Framework Directive (WFD) aims to deliver good ecological status (GES) for Europe's waters. It prescribes the use of economic principles, such as derogation from GES on grounds of disproportionate costs of mitigation. This paper proposes an application of the proportionality principle to mitigation of phosphorus (P) pollution of 544 Scottish lochs at national and local water body scales. P loading estimates were derived from a national diffuse pollution screening tool. For 293 of these lochs (31% of the loch area), GES already occurred. Mitigation cost-effectiveness was assessed using combined mitigation cost curves for managed grassland, rough grazing, arable land, sewage and septic tank sources. These provided sufficient mitigation (92% of national P load) for GES to be achieved on another 31% of loch area at annualised cost of £2.09 m/y. Mitigation of the residual P loading preventing other lochs achieving GES was considered by using a "mop-up" cost of £200/kg P (assumed cost effectiveness of removal of P directly from lochs), leading to a total cost of £189 m/y. Lochs were ranked by mitigation costs per loch area to give a national scale marginal mitigation cost curve. A published choice experiment valuation of WFD targets for Scottish lochs was used to estimate marginal benefits at national scale and combined with the marginal cost curve. This gave proportionate costs of £5.7 m/y leading to GES in 72% of loch area. Using national mean marginal benefits with a scheme to estimate changes in individual loch value with P loading gave proportionate costs of £25.6 m/y leading to GES in 77% of loch area (491 lochs).

    This report presents results of a marine environmental radioactivity monitoring survey of intertidal and underwater areas around the former United States Naval Base at Holy Loch, carried out jointly by DRPS and U.S. Navy staff in March 1992 following the departure of U.S. Navy submarine support facilities. Results are reported for in-situ measurements and subsequent laboratory analysis of over 460 samples covering over 150 separate locations. Included is a report by the U.S. Navy summarising their results for the survey. Cobalt-60, the nuclide of major importance in naval discharges, was detected in a number of samples from the intertidal zone and in all underwater sediment samples, but concentrations were low. The calculated annual radiation dose commitment to the most exposed members of the public due to cobalt-60 is 1 μSv. (Author)

  3. Forcing mechanisms and hydrodynamics in Loch Linnhe, a dynamically wide Scottish estuary

    Rabe, Berit; Hindson, Jennifer

    2017-09-01

    Hydrodynamic conditions in Loch Linnhe, a dynamifcally wide estuary on the west coast of Scotland, are primarily influenced by wind forcing, freshwater input, and tides. Winds in the region are orographically steered along the axis of the estuary due to surrounding mountains. A large rainfall catchment area results in a large freshwater inflow into Loch Linnhe which in turn produces low salinity waters at the head of the estuary. This, combined with a connection to the open sea with coastal salinities, leads to salinity gradients in the horizontal and vertical. Even though a range of observational programmes have focussed on Loch Linnhe, the literature still lacks an evaluation of its physical dynamics. Here we present a first description of the hydrodynamics in Loch Linnhe based on observations. Wind stress predominantly influences the surface layer, especially at low frequencies and with a stronger influence than tides during neap tides. The buoyancy-driven flow due to the large river runoff influences the circulation independent of wind stress. Seasonal (spring, autumn) and interannual (2011, 2012) variability of water masses occur especially in the surface layer. Tides are dominated by the semi-diurnal constituent M2 with tidal ellipses aligned in the along-estuary direction and a stronger influence during spring tides compared to wind. An evaluation of dimensionless numbers reveal laterally and vertically sheared exchange flows. Compared to other Scottish estuaries Loch Linnhe is wide enough to be influenced by the Earth's rotation and demonstrates an enhanced freshwater outflow along its north-western coast as the freshwater is diverted to the right in the direction of the flow. These observed patterns are important for the sustainable environmental management of this socio-economically valuable region, e.g. through their relevance to aquaculture pathogen transmission patterns. A thorough understanding of the dynamics of the system is essential for a

  4. Recovery from acidification of lochs in Galloway, south-west Scotland, UK: 1979-1998

    R. C. Ferrier

    2001-01-01

    Full Text Available The Galloway region of south-west Scotland has historically been subject to long-term deposition of acidic precipitation which has resulted in acidification of soils and surface waters and subsequent damage to aquatic ecology. Since the end of the 1970s, however, acidic deposition has decreased substantially. The general pattern is for a rapid decline in non-marine sulphate in rainwater over the period 1978-1988 followed by stable concentrations to the mid-1990s. Concentrations of nitrate and ammonium in deposition have remained constant between 1980 and 1998. Seven water quality surveys of 48 lochs in the Galloway region have been conducted between 1979 and 1998. During the first 10 years, from 1979, there was a major decline in regional sulphate concentrations in the lochs, which was expected to have produced a decline in base cations and an increase in the acid neutralising capacity. But sea-salt levels (as indicated by chloride concentrations were approximately 25% higher in 1988 than in 1979 and thus short-term acidification due to sea-salts offset much of the long-term recovery trend expected in the lochs. During the next 10 years, however, the chloride concentrations returned to 1979 levels and the lochs showed large increases in acid neutralising capacity despite little change in sulphate concentrations. From the observed decline in sulphate deposition and concentrations of sulphate in the lochs, it appears that approximately 75% of the possible improvement in acid neutralising capacity has already occurred over the 20-year period (1979-1998. The role of acid deposition as a driving factor for change in water chemistry in the Galloway lochs is confounded by concurrent changes in other driving variables, most notably, factors related to episodic and year-to-year variations in climate. In addition to inputs of sea-salts, climate probably also influences other chemical signals such as peaks in regional nitrate concentrations and the sharp

  6. Reduction in cryptosporidiosis associated with introduction of enhanced filtration of drinking water at Loch Katrine, Scotland.

    Previous evidence has suggested an association between cryptosporidiosis and consumption of unfiltered drinking water from Loch Katrine in Scotland. Before September 2007, the water was only micro-strained and chlorinated; however, since that time, coagulation and rapid gravity filtration have been installed. In order to determine risk factors associated with cryptosporidiosis, including drinking water, we analysed data on microbiologically confirmed cases of cryptosporidiosis from 2004 to 2010. We identified an association between the incidence of cryptosporidiosis and unfiltered Loch Katrine drinking water supplied to the home (odds ratio 1.86, 95% confidence interval 1.11-3.11, P = 0.019). However, while filtration appears to be associated with initially reduced rates of cryptosporidiosis, evidence suggests it may paradoxically make those consumers more susceptible to other transmission routes in the long-term. These findings support implementation of similar treatment for other unfiltered drinking-water supplies, as a means of reducing cryptosporidiosis associated with drinking water.

    1999-01-01

    Baltimore City and its metropolitan area are supplied with water from three reservoirs, Liberty Reservoir, Prettyboy Reservoir, and Loch Raven Reservoir. Prettyboy and Loch Raven Reservoirs are located on the Gunpowder Falls (figure 1). The many uses of the reservoir system necessitate coordination and communication among resource managers. The 1996 Amendment to the Safe Drinking Water Act require States to complete source-water assessments for public drinking-water supplies. As part of an ongoing effort to provide safe drinking water and as a direct result of these laws, the City of Baltimore and the Maryland Department of the Environment (MDE), in cooperation with other State and local agencies, are studying the Gunpowder Falls Basin and its role as a source of water supply to the Baltimore area. As a part of this study, the U.S. Geological Survey (USGS), in cooperation with the Maryland Geological Survey (MGS), with funding provided by the City of Baltimore and MDE, is examining sediment accumulation in Loch Raven Reservoir. The Baltimore City Department of Public Works periodically determines the amount of water that can be stored in its reservoirs. To make this determination, field crews measure the water depth along predetermined transects or ranges. These transects provide consistent locations where water depth, or bathymetric, measurements can be made. Range surveys are repeated to provide a record of the change in storage capacity due to sediment accumulation over time. Previous bathymetric surveys of Loch Raven Reservoir were performed in 1943, 1961, 1972, and 1985. Errors in data-collection and analysis methods have been assessed and documented (Baltimore City Department of Public Works, 1989). Few comparisons can be made among survey results because of changing data-collection techniques and analysis methods.

    Full Text Available We report an application of the Science and Policy Integration for Coastal System Assessment (SPICOSA Systems Approach Framework (SAF to Loch Fyne, a fjord in western Scotland. The issue was the potential for conflict between shellfish aquaculture and recreational use for yachting. This was investigated by building an ecological-economic model to simulate: (1 release of modern anti-fouling compounds by recreational boats; (2 dilution of these in the upper layers of the loch by exchange with the sea; (3 their effects on photosynthesis by phytoplankton; (4 the role of phytoplankton (along with non-algal particulate matter in providing food for mussels; (5 the growth of seeded mussels to harvest, determining (6 the cash input to farms, offset by their costs and allowing (7 the farm revenue to be compared with that from marinas used to berth the yachts. It was concluded from simulations that no noticeable effect on mussel harvest would occur (from this route for any likely number of yachts berthed in the loch. The application took place in consultation with a local environmental forum and a small reference group of public officials; we reflect on it in the context of a 3-component schema for the science-policy interface and changes in the culture of UK science.

  12. The abundance of large, piscivorous Ferox Trout (Salmo trutta in Loch Rannoch, Scotland

    2016-11-01

    Full Text Available Background Ferox Trout are large, long-lived piscivorous Brown Trout (Salmo trutta. Due to their exceptionally large size, Ferox Trout are highly sought after by anglers while their life-history strategy, which includes delayed maturation, multiphasic growth and extended longevity, is of interest to ecological and evolutionary modelers. However, despite their recreational and theoretical importance, little is known about the typical abundance of Ferox Trout. Methods To rectify this situation a 16 year angling-based mark-recapture study was conducted on Loch Rannoch, which at 19 km2 is one of the largest lakes in the United Kingdom. Results A hierarchical Bayesian Jolly-Seber analysis of the data suggest that if individual differences in catchability are negligible the population of Ferox Trout in Loch Rannoch in 2009 was approximately 71 fish. The results also suggest that a single, often unaccompanied, highly-experienced angler was able to catch roughly 8% of the available fish on an annual basis. Discussion It is recommended that anglers adopt a precautionary approach and release all trout with a fork length ≥400 mm caught by trolling in Loch Rannoch. There is an urgent need to assess the status of Ferox Trout in other lakes.

    The post glacial sediments of Loch Lomond contain a well defined band of marine deposited material which is overlain and underlain by freshwater deposited sediment. The chronology of the sedimentary sequence has been well established by radiocarbon dating and, in the southern basin of the Loch, the marine sediment band is of the order of 1 m thick and typically occurs at a depth of about 3 to 4 m beneath the sediment surface. Previous work has established that the marine deposited sediment contains enhanced concentrations of iodine and bromine relative to the contiguous freshwater sediments and that dissolution of halogen elements from the marine sediments generates a concentration gradient, with consequent diffusive transport, of these elements in the sediment interstitial water. This environment is thus highly suitable for investigation of the rate of transport of halogen elements through the sediment a topic of direct relevance to radioactive waste disposal in the context of far field migration of 129 I. Previous studies resulted in successful modelling of the diffusive transport of bromine in the interstitial water of the sediment on the basis of the observed concentration profile for total bromine in the water. This work was, however, of restricted value since (1) speciation was not determined (2) archived sediment was used and (3) samples were processed and analyzed under ambient laboratory conditions. The objective of the work described in this report was to collect a new core of Loch Lomond sediment and to carry out appropriate analyses to overcome the above limitations

    We report on a first deployment of a GNSS Wave Glider designed for precise, unmanned, autonomous, mobile self-propelled sea level and sea state measurement in the open ocean. The Wave Glider, equipped with a dual frequency GPS+GLONASS receiver, was deployed in Loch Ness, Scotland, autonomously travelling 32 km in a north-easterly direction along the length of the loch in 26 hours, propelled by energy generated from waves of typical amplitude only 100-150 mm and frequency on the order 0.5-1 Hz. The Wave Glider GNSS data were analysed using a post-processed kinematic GPS+GLONASS precise point positioning (PPP) approach, which were quality controlled using double difference GPS kinematic processing with respect to onshore reference stations at either end of the loch. The PPP heights of the loch's surface revealed a clear geoid gradient of about 30 mm/km (i.e. just under 1 m over the whole length of the loch), very similar to both the EGM2008 and OSGM02 geoid models, demonstrating the potential use of a GNSS Wave Glider for marine geoid determination. After applying a low pass filter, the GNSS heights showed local deviations from both EGM2008 and OSGM02, potentially caused by omission errors or a lack of gravity data over Loch Ness. In addition to dual frequency GNSS data, the Wave Glider also recorded inclinometer data, bathymetry, and surface currents, which, in combination with tide gauge and wind data, were used to further control and interpret the GNSS time series.

  15. Placing lochs in their landscapes: linking landscape ecology, ecohydrology and conservation interest in a changing climate

    2011-12-01

    Scotland is a country with outstanding freshwater systems providing multiple social, economic and cultural functions as well as ecological services of international importance. Scotland's lakes (locally termed lochs) occupy approximately 3% of the country's land mass and contain more than 90% of Great Britain's total freshwater resource. With over 25,000 lochs (surface area greater than 0.1 hectares) standing freshwaters are an iconic part of Scotland's landscape and they come in a myriad of forms and sizes contributing outstanding geodiversity as well as habitats of international importance for numerous species of conservation interest. There is undoubtedly a need to protect the conservation interests of designated sites in the face of changing loch and catchment pressures - which include diffuse pollutants, morphological modification, recreation and invasive species. Climate change presents a new set of challenges with potential impacts across the entire standing water resource base and predicting how these systems might respond to these changes greatly amplifies uncertainties implicit in their environmental management. Global climate change is predicted to be a major cause of change across all ecosystems and there are particular concerns about impacts on freshwater systems due to the coupling of impacts to both hydrology and ecology. Climate change is likely to affect the hydrological cycle in a number of ways, most significantly through changing temperature and precipitation patterns, intensities and extremes. These changes, coupled with reduced snow and ice cover, frequency and duration, will lead to changes in soil moisture conditions and subsequently runoff. This is turn will impact on river flow, loch water levels, epilimnic temperatures, nutrient availability and, subsequently, the ecological structure and function of the entire standing water system. For some species these habitat changes will push them to the very limits of their natural tolerances and a

  17. Storage Capacity and Sedimentation of Loch Lomond Reservoir, Santa Cruz, California, 1998

    Science.gov (United States)

    McPherson, Kelly R.; Harmon, Jerry G.

    2000-01-01

    In 1998, a bathymetric survey was done to determine the storage capacity and the loss of capacity owing to sedimentation of Loch Lomond Reservoir in Santa Cruz County, California. Results of the survey indicate that the maximum capacity of the reservoir is 8,991 acre-feet in November 1998. The results of previous investigations indicate that storage capacity of the reservoir is less than 8,991 acre-feet. The storage capacity determined from those investigations probably were underestimated because of limitations of the methods and the equipment used. The volume of sedimentation in a reservoir is considered equal to the decrease in storage capacity. To determine sedimentation in Loch Lomond Reservoir, change in storage capacity was estimated for an upstream reach of the reservoir. The change in storage capacity was determined by comparing a 1998 thalweg profile (valley floor) of the reservoir with thalweg profiles from previous investigations; results of the comparison indicate that sedimentation is occurring in the upstream reach. Cross sections for 1998 and 1982 were compared to determine the magnitude of sedimentation in the upstream reach of the reservoir. Results of the comparison, which were determined from changes in the cross-sectional areas, indicate that the capacity of the reservoir decreased by 55 acre-feet.

    The Loch Vale watershed project is a long-term research and monitoring program located in Rocky Mountain National Park that addresses watershed-scale ecosystem processes, particularly as they respond to atmospheric deposition and climate variability. Measurements of precipitation depth, precipitation chemistry, discharge, and surface-water quality are made within the watershed and elsewhere in Rocky Mountain National Park. As data collected for the program are used by resource managers, scientists, policy makers, and students, it is important that all data collected in Loch Vale watershed meet high standards of quality. In this report, data quality was evaluated for precipitation, discharge, and surface-water chemistry measurements collected during 2003-09. Equipment upgrades were made at the Loch Vale National Atmospheric Deposition Program monitoring site to improve precipitation measurements and evaluate variability in precipitation depth and chemistry. Additional solar panels and batteries have been installed to improve the power supply, and data completeness, at the NADP site. As a result of equipment malfunction, discharge data for the Loch Outlet were estimated from October 18, 2005, to August 17, 2006. Quality-assurance results indicate that more than 98 percent of all surface-water chemistry measurements were accurate and precise. Records that did not meet quality criteria were removed from the database. Measurements of precipitation depth, precipitation chemistry, discharge, and surface-water quality were all sufficiently complete and consistent to support project data needs.

    1991-01-01

    One of the four natural analogue sites being investigated by the British Geological Survey is Loch Lomond, Scotland. Naturally occurring halogen elements (Cl, Br and I) have been migrating from a thin marine horizon into overlying freshwater deposits by a diffusion process which has been occurring for at least 5 400 years. This report summarizes the main findings accumulated since 1983 when the work was first begun, and provides a modelling interpretation of the measured concentration-depth profiles using a new numerical code called Diagen. The release rates of I and Br from the organic matter association in the shallow buried marine layer are very slow; subsequent anion movement by diffusion is affected by tortuosity differences in the sediments rather than by chemical reaction with the sediments. The bulk of the evidence supports conservative transport of iodide, bromide and chloride anions towards the sediment/loch interface. The report discusses some implications of the findings

    We reconstruct the pre-acidification pH of the Round Loch of Glenhead for 1800 AD using three diatom-pH transfer functions and a diatom-cladocera modern analogue technique (MAT), and compare these palaeo-data with hindcast data for the loch using the dynamic catchment acidification model MAGIC. We assess the accuracy of the transfer functions by comparing pH inferences from contemporary sediment and sediment trap diatom samples from the lake with measured pH from the UK Acid Waters Monitoring Network. The results from the transfer functions estimate the pH in 1800 to have been between 5.5. and 5.7, the MAT approach estimates pH at 5.8 and the MAGIC hindcast (for 1850) is pH 6.1. Whilst we have no independent method of assessing which of these values is most accurate, the disagreement between the two approaches indicates that further work is needed to resolve the discrepancies. - Methods of reconstructing pre-acidification pH for an acidified Scottish loch compared

    Red mud is a by-product of alumina production. Little is known about the long-term fate of red mud constituents in fresh waters or of the processes regulating recovery of fresh waters following pollution control. In 1983, red mud leachate was diverted away from Kinghorn Loch, UK, after many years of polluting this shallow and monomictic lake. We hypothesised that the redox-sensitive constituents of red mud leachate, phosphorus (P), arsenic (As) and vanadium (V), would persist in the Kinghorn Loch for many years following pollution control as a result of cycling between the lake bed sediment and the overlying water column. To test this hypothesis, we conducted a 12-month field campaign in Kinghorn Loch between May 2012 and April 2013 to quantify the seasonal cycling of P, As, and V in relation to environmental conditions (e.g., dissolved oxygen (DO) concentration, pH, redox chemistry and temperature) in the lake surface and bottom waters. To confirm the mechanisms for P, As and V release, a sediment core incubation experiment was conducted using lake sediment sampled in July 2012, in which DO concentrations were manipulated to create either oxic or anoxic conditions similar to the bed conditions found in the lake. The effects on P, As, and V concentrations and species in the water column were measured daily over an eight-day incubation period. Phosphate (PO 4 -P) and dissolved As concentrations were significantly higher in the bottom waters (75.9 ± 30.2 μg L -1 and 23.5 ± 1.83 μg L -1 , respectively) than in the surface waters (12.9 ± 1.50 μg L -1 and 14.1 ± 2.20 μg L -1 , respectively) in Kinghorn Loch. Sediment release of As and P under anoxic conditions was confirmed by the incubation experiment and by the significant negative correlations between DO and P and As concentrations in the bottom waters of the lake. In contrast, the highest dissolved V concentrations occurred in the bottom waters of Kinghorn Loch under oxic conditions (15.0

  6. An assessment, using stable isotopes, of the importance of allochthonous organic carbon sources to the pelagic food web in Loch Ness

    1998-01-01

    The natural abundance of stable isotopes (δ13C and δ1315N) was determined for components of the pelagic food web in Loch Ness, a deep oligotrophic lake in northern Scotland, and compared with values from the inflow rivers and the catchment vegetation. Phytoplankton δ13C was low compared to values reported from other lakes, possibly reflecting a high use of 13C-depleted carbon dioxide from respired organic matter before further isotopic fractionation during photosynthesis. Phytoplankton δ13C was appreciably lower than that of dissolved and particulate organic matter (DOM and POM) in the loch. The DOM and POM were evidently overwhelmingly of allochthonous origin and ultimately derived from terrestrial plant detritus. The distinctive δ13C values for phytoplankton and detritus in the loch allowed the use of food sources by grazing crustacean zooplankton to be assessed, and the contributions of phytoplankton carbon and detrital carbon to zooplankton total body carbon appeared to be about equal. Comparison of δ13C and δ15N values for zooplankton and fish allowed assessment of trophic structure in the loch. The very high dependence of the pelagic food web in Loch Ness on allochthonous organic matter inputs from the catchment may be exceptional in a large lake, but has important implications for our understanding of lake ecosystem processes as well as for lake management.

    Relationships between concentrations of rock weathering products and discharge provide insight into the interactions between climate and solute dynamics. This concentration-discharge (C-Q) relationship is especially interesting in high alpine regions, due to their susceptibility to changes in the timing and magnitude of snowmelt. Previous studies looking at C-Q relationships have concluded that concentrations of conservative solutes remain relatively constant as discharge varies; however, these results may be due to relatively small sample sizes, especially at higher discharge values. Using water chemistry data collected regularly by the U.S. Geological Survey from Loch Vale, a high-elevation catchment in Rocky Mountain National Park, C-Q relationships were examined to determine possible geochemical controls on stream solute concentrations. A record of over 20 years of C-Q data resulted in a pattern that shows little variation in conservative solute concentrations during base flow and larger variations in concentrations around peak discharge. This observed pattern is consistent with accumulation of solutes in pore water during base flow, which are then flushed out and diluted by snowmelt. Further evidence of this flushing out mechanism is found in patterns of hysteresis that are present in annual C-Q relationships. Before peak discharge, concentrations of weathering products are higher than after peak discharge at similar values of discharge. Based on these observations, we hypothesize that the geochemical processes controlling stream chemistry vary by season. During the winter, solute concentrations are transport-limited due to slow subsurface flushing resulting in concentrations that are effectively constant and close to equilibrium. During the spring and summer, concentrations drop sharply after peak discharge due to a combination of dilution and reaction-limited processes under conditions with faster subsurface flow and continued snowmelt. This study provides

  16. Rare earth mineralisation in the Cnoc nan Cuilean intrusion of the Loch Loyal Syenite Complex, northern Scotland

    Due to growing global concerns about security of rare earth element (REE) supply, there is considerable interest in identifying new deposits and in understanding the processes responsible for their formation. Ongoing studies by BGS on potential indigenous resources have focused on the Caledonian alkaline intrusive complexes of north-west Scotland. The highest values of total rare earth oxide (TREO) have been found in the Cnoc nan Cuilean intrusion of the Loch Loyal Complex in Sutherland. The Loch Loyal Syenite Complex comprises three intrusions: Ben Loyal, Beinn Stumanadh and Cnoc nan Cuilean. The Cnoc nan Cuilean intrusion, which covers an area of about 3 km2, can be subdivided into two zones: a Mixed Syenite Zone (MSZ) and a later Massive Leucosyenite Zone (MLZ). Evidence from field mapping and 3D-modelling suggests that the melasyenites were passively emplaced to form a lopolith concordant with the Moine and Lewisian country rocks. A later episode of leucosyenitic magmatism caused mixing and mingling with the melasyenite forming the MSZ. Continued intrusion of leucosyenite melts then formed the MLZ [1]. The melasyenites are enriched in TREO relative to the leucosyenites with average values of 3800 ppm and 1400 ppm respectively. The highest contents, up to 20 000 ppm TREO, are found in narrow biotite-magnetite-rich veins identified in a single stream section near the eastern margin of the intrusion. All lithologies are light rare earth element (LREE) dominated with high concentrations of Ba and Sr and low levels of Nb and Ta. Various REE-bearing minerals are present but allanite is dominant, being present in all major magmatic lithologies and the biotite-magnetite veins. Three generations of allanite have been identified: a late-magmatic phase rimming apatite; allanite micro veinlets cross-cutting the syenite; and a third phase only observed in the biotite-magnetite veins. TREO concentrations of the different allanite generations are similar, averaging 22%. The

    Full Text Available In seinem Beitrag zeichnet Christian Zolles die 'Globalisierung des Himmels seit 1783' nach und versucht anhand der Entwicklungen in der Luftfahrt die Konzepte 'Macht', 'Souveränität' und 'Herrschaft' zu umreißen. So zeigen die frühen Ballonflüge die Grenzen absolutistischer Repräsentationsmacht auf und spiegeln sowohl das neue erhabene Raumbewusstsein als auch den revolutionären Freiheitsdrang des Bürgertums. Gleichzeitig mit dem demokratischen Perspektivenwechsel setzt sich die politische Imagination eines charismatischen 'großen Mannes' durch, der die Vielfalt und Widersprüchlichkeit der Bevölkerungsmenge aufheben und volkssouveräne Tatkraft verkörpern kann. Demgegenüber steht der medienkritische Blick des 'kleinen Mannes' (mit Jean Pauls Luftschifffahrer Giannozzo als Archetyp, der mit dem Verweis auf die Figur des Sprachspielers (Norbert Meder in medienpädagogische Richtung gedeutet wird. In his contribution, Christian Zolles traces the 'globalization of the sky since 1783' and tries to outline the concepts of 'power', 'sovereignty' and 'dominion' on the basis of developments in aviation. Thus, the early balloon flights reveal the boundaries of absolutist representation power and reflect both the new sublime awareness of the space as well as the revolutionary freedom impulse of the bourgeoisie. At the same time, the political imagination of a charismatic 'great man', which undermines the diversity and inconsistency of the population, Sovereign power. On the other hand, the media-critical view of the "little man" (with Jean Paul's airship commander Giannozzo as an archetype is interpreted in the media-pedagogical direction with the reference to the figure of the language player (Norbert Meder.

    The 239+240 Pu activity profile is determined for a sediment core collected from 170-m depth at Loch Ness, Scotland. These measurements use magnetic sector inductively coupled plasma mass spectrometry for rapid determination of Pu activities and 240 Pu/ 239 Pu atom ratios. A 239+240 Pu detection limit of 0.1 Bq/kg is obtained for 2 g of acid-leached sediment; 242 Pu is used as a spike isotope. The Pu activity profile exhibits a maximum of 42.7±0.3 Bq/kg 239+240 Pu in the 9-10-cm depth interval. The position of this maximum coincides with peaks in the 241 Am and 137 Cs activity profiles. These peak activities are ascribed to the 1963/1964 peak fallout from atmospheric testing of nuclear weapons. The 240 Pu/ 239 Pu atom ratios are in the range 0.15-0.20, in agreement with the expected range of 0.166-0.194 for Northern Hemisphere fallout, and do not suggest the presence of other contributing sources. This study demonstrates that ICPMS has considerable potential for rapid determination of the chronology of post-1950 sediments, and also for validating 210 Pb dates where chronologies over longer time-scales are needed

    In the majority of salmon farming countries, production occurs in zones where practices are coordinated to manage disease agents such as Lepeophtheirus salmonis. To inform the structure of zones in specific systems, models have been developed accounting for parasite biology and system hydrodynamics. These models provide individual system farm relationships, and as such, it may be beneficial to produce more generalized principles for informing structures. Here, we use six different forcing scenarios to provide simulations from a previously described model of the Loch Linnhe system, Scotland, to assess the maximum dispersal distance of lice particles released from 12 sites transported over 19 day. Results indicate that the median distance travelled is 6.1 km from release site with management areas developed for infectious salmon anaemia control may also have properties appropriate for salmon lice management in Scottish coastal waters. Additionally, general numerical descriptors of the simulated relative lice abundance reduction with increased distance from release location are proposed. © 2015 Crown copyright. © 2015 John Wiley & Sons Ltd.

  1. Nonlinear internal waves and plumes generated in response to sea-loch outflow, AUV, and time-lapse photography observations

    The tidally modulated outflow of brackish water from a sea loch forms a thin surface layer that propagates into the coastal ocean as a buoyant gravity current, transporting nutrients and sediments, as well as fresh water, heat and momentum. The fresh intrusion both propagates into and generates a strongly stratified environment which supports trains of nonlinear internal waves (NLIWs). NLIWs are shown to propagate ahead of this buoyancy input in response to propagation of the outflow water into the stratified environment generated by the previous release as well as in the opposing direction after the reflection from steep bathymetry. Oblique aerial photographs were taken and photogrammetric rectification led to the identification of the buoyant intrusion and the subsequent generation of NLIWs. An autonomous underwater vehicle (AUV) was deployed on repeated reciprocal transects in order to make simultaneous CTD, ADCP, and microstructure shear measurements of the evolution of these phenomena in conjunction with conventional mooring measurements. AUV-based temperature and salinity signals of NLIWs of depression were observed together with increased turbulent kinetic energy dissipation rates of over 2 orders of magnitude within and in the wake of the NLIWs. Repeated measurements allow a unique opportunity to investigate the horizontal structure of these phenomena. Simple metric scaling demonstrates that these processes are likely to be feature of many fjordic systems located on the west coast of Scotland but may also play a key role in the assimilation of the outflow from many tidally dominated fjordic systems throughout the world.

    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.

    This paper presents results of geochemical investigations of lake sediments from the karst lake An Loch Mor, Aran Islands, including the first highly resolved record of atmospheric Roman Pb pollution for Ireland. The natural Pb influx into the lake is largely contributed by 3 Pb components, which differ in their isotopic composition: detrital influx of Pb from the siliciclastic input, dissolved influx of Pb released by weathering of the local limestone, and dissolved influx of seawater Pb. The balance between the 3 Pb components varies in concert with the hydrological evolution of the lake. The influx of Pb in dissolved form is estimated by geochemical mass balance assuming that the siliciclastic influx is characterised by the Pb/Al-ratio of the Late Glacial clastic sediments. It typically accounts for 50-80% of total Pb input in the Holocene sediments of An Loch Mor. The natural dissolved influxes of Pb, Sc, and Y reach a similar order of magnitude. Normalisation with Sc and Y is applied to quantify contributions from anthropogenic Pb. Based on continuous sampling of 1 cm sample slices, variations in the influx of Roman Pb could be reconstructed at a time resolution of c. 5 a. Combined geochemical and Pb isotope mass balance is used to characterise the isotopic composition of anthropogenic Pb. Distinctly enhanced influx of anthropogenic Pb occurs in the 1st and 2nd century AD and shows high variability on decadal scale. This is in contrast to central European Pb records, which document a gradual increase and decrease in ancient atmospheric pollution by Roman Pb. The reconstructed high variability in the influx of Roman Pb in An Loch Mor documents variations in the wind regime of western Europe, temporarily favouring the transport of atmospheric Pb to western Ireland.

The largely Mississippian strata of the Kilpatrick Hills, located at the western end of the Scottish Midland Valley, enclose several macrofossil floras that together contain ca 21 organ-species of permineralised plants and ca 44 organ-species of compressed plants, here estimated to represent 25 whole-plant species (Glenarbuck = nine, Loch Humphrey Burn Lower = 11, Upper = seven. The most significant locality is the internationally important volcanigenic sequence that is reputedly intercalated within the Clyde Plateau Lava Formation at Loch Humphrey Burn, where ca 30 m of reworked tuffs and other clastic sediments enclose one of the world’s most important terrestrial lagerstätten of this period. We here explore the palaeoecology and palaeoenvironments of the locality, and elucidate its controversial age. Methods. Repeated re-excavation of key exposures allowed recognition of five main depositional units, differing in thickness from 4 m to 12 m.

    Trace elements, hydrocarbons and radium-226 concentrations were analyzed in water, sediment and biota from the Loch Katrine wetlands at Park County, WY in 1992. This study was designed to determine if produced waters pose a risk to aquatic birds inhabiting the wetlands. The radium-226 concentration recorded at the Sidney Battery Discharge in July, 93.7 pCi/l, exceeded WY DEQ's 60 pCi/l standard for the protection of aquatic life. Water quality acute criteria were exceeded for arsenic, Custer Lake, July, and for zinc, Sidney Battery discharge, April. Radium-226 concentrations in sediments from Custer Lake and Sidney Battery Discharge exceeded the 3 pCi/g background for Oregon Basin soils. The radium-226 concentration in aquatic vegetation, Custer Lake, 29.5 pCi/g, greatly exceeded the 2.9 pCi/g average concentration found in plants growing in uranium mill tailings in South Dakota. Radium-226 in aquatic vegetation may be available to aquatic birds. Oil and grease concentrations, Sidney Battery Discharge, exceeded the 10 mg/l standard of WY DEQ. Sediment hydrocarbon concentrations were highest at Sidney Battery Discharge, 6.376 μg/g, followed by Custer Lake, 1.104 μg/g. Benzo(a)pyrene was not detected in gadwalls from Loch Katrine but was detected in northern shovelers from Custer Lake. Benzo(a)pyrene concentrations in northern shoveler bile ranged from 500 to 960 ng/g (ppb) wet weight. Benzo(a)pyrene concentrations in shovelers is indicative of exposure to petroleum hydrocarbons

    Lieutenant Colonel Robert Kenneth Wilson (1899-1969) was a surgeon who fought in both world wars and joined the Special Operations Executive parachuting behind enemy lines into Holland, France and Borneo, the last mission being with Australian forces (Semut II). He was an expert on firearms and gave opinion on ballistics at the Old Bailey during the 1930s. He also wrote a definitive text on automatic pistols with editions published in 1943 and 1975. He was an Edinburgh Fellow (1926), who had a practice in general surgery and gynaecology in Queen Anne Street during the 1930s. He took the famous 1934 'surgeon's photo' of the Loch Ness monster that was not admitted to be a hoax until 1994. After World War II, he became the first surgical specialist to work in the public service of the then Territory of Papua and New Guinea (1950-1956), where he wrote several papers on surgical topics. He married Gwen (1924), the daughter of Henrietta Gulliver, an Australian painter. They had two sons, Richard and Phillip. After practice he retired to Melbourne where he died of carcinoma oesophagus.

    Concern about security of supply of critical elements used in new technologies, such as the Rare Earth Elements (REE), means that it is increasingly important to understand the processes by which they are enriched in crustal settings. High REE contents are found in syenite-dominated alkaline complexes intruded along the Moine Thrust Zone, a major collisional zone in north-west Scotland. The most northerly of these is the Loch Loyal Syenite Complex, which comprises three separate intrusions. One of these, the Cnoc nan Cuilean intrusion, contains two mappable zones: a Mixed Syenite Zone in which mafic melasyenite is mixed and mingled with leucosyenite and a Massive Leucosyenite Zone. Within the Mixed Syenite Zone, hydrothermal activity is evident in the form of narrow altered veins dominated by biotite and magnetite; these are poorly exposed and their lateral extent is uncertain. The REE mineral allanite is relatively abundant in the melasyenite and is extremely enriched in the biotite-magnetite veins, which have up to 2 % total rare earth oxides in bulk rock analyses. An overall model for development of this intrusion can be divided into three episodes: (1) generation of a Light Rare Earth Element (LREE)-enriched parental magma due to enrichment of the mantle source by subduction of pelagic carbonates; (2) early crystallisation of allanite in melasyenite, due to the saturation of the magma in the LREE; and (3) hydrothermal alteration, in three different episodes identified by petrography and mineral chemistry, generating the intense enrichment of REE in the biotite-magnetite veins. Dating of allanite and titanite in the biotite-magnetite veins gives ages of c. 426 Ma, overlapping with previously published crystallisation ages for zircon in the syenite.

    Der deutsche Schriftsteller Thomas LEHR liest am 23. März 2006 aus seinem Roman '42', einem philosophischen Abenteuerroman über die Suche nach der Zeit, erzählt in einer funkelnden und souveränen Sprache. Eine Welt von vernichtender Schönheit und bizarren Schrecken wartet auf eine Besuchergruppe, die in der Nähe von Genf die unterirdischen Anlagen des Forschungszentrums für Teilchenphysik CERN besichtigt. Als sie um 12:47:42 wieder ans Tageslicht tritt, scheint ganz Europa in einen Dornröschenschlaf gefallen. Allein die 70 Besucher können sich noch bewegen.

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

    1982-01-01

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

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

    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.

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

    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.

  16. Toward an Intelligent Ion Mobility Spectrometer (IMS)

    International Nuclear Information System (INIS)

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

    2003-01-01

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

  17. Grand Prix Eurovision: Eine Fankultur im Medienzeitalter

    2017-06-01

    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..

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

  6. bildbild – visuelle Kompetenz im Unterricht

    Directory of Open Access Journals (Sweden)

    Norbert Grube

    2013-05-01

    Full Text Available Der vorliegende Artikel stellt das Webseiten-Projekt bildbild vor. Der Webseite liegt die Motivation zugrunde, Schülerinnen und Schüler für ein Nachdenken über globale Themen zu sensibilisieren. Ein solches Nachdenken ist immer auch eines über bildlich vermittelte Wirklichkeit. Es ist mit bildbild ein Anliegen, angesichts einer allseits konstatierten «Bilderflut» ein didaktisches Medium zu entwickeln, das einen Fundus an historischen und aktuellen Fotografien zur Verfügung stellt und diese so aufbereitet, dass sie gerade nicht hinter ihrer illustrativen Funktion verschwinden. Dadurch sollen die Bilder für ein selbständiges Lernen auf dem Weg hin zu einer visuellen Kompetenz einsetzbar gemacht werden. Der Beitrag beleuchtet die Entwicklung der Webseite vor dem Hintergrund kulturkritischer Haltungen zum Bild seit der Moderne sowie im Rahmen dessen, was seit den 1970er Jahren im pädagogischen Kontext als Visual Literacy diskutiert und gefördert wird. Dabei wird auch auf die medialen Potenziale einer Webseite für die Bildlesekompetenz von Jugendlichen eingegangen.

    1982-01-01

    A review is provided of the wide-ranging observational programs of 25 stations operating on and around the continent of Antarctica during the International Magnetospheric Study (IMS). Attention is given to observations of geomagnetism, short period fluctuations of the earth's electromagnetic field, observations of the ionosphere and of whistler mode signals, observational programs in ionospheric and magnetospheric physics, upper atmosphere physics observations, details of magnetospheric programs conducted at Kerguelen, H-component magnetograms, magnetic field line oscillations, dynamic spectra of whistlers, and the variation of plasmapause position derived from recorded whistlers. The considered studies suggest that, in principle, if the level of magnetic activity is known, predictions can be made concerning the time at which the trough occurs, and the shape and the movement of the main trough

    Full Text Available Die Medienfront ist heute ein wichtiger Kriegsschauplatz, den viele neben Land, Wasser und Luft für gleich wichtig halten. Terroristen fühlen sich in sozialen Medien wohler als man denken könnte. Im Netz können sie die asymmetrische Kräfteverteilung überwinden, die sie in der offenen Feldschlacht unterlegen sein ließe. Terroristen machen sich das Bild zur Waffe und produzieren erst durch die Positionierung an der Medienfront Sinn in ihren Taten. Ohne ein Bekennerschreiben, ein Abschiedsvideo des Attentäters oder ein letztes Posting im sozialen Netzwerk wäre ein Bombenanschlag nichts als ein Kapitalverbrechen. Durch die terroristische Kommunikationsstrategie wird das Verbrechen erst zum terroristischen Akt. Das ist die theoretische Grundannahme dieses Aufsatzes. Ohne Medienberichterstattung könnten terroristische Organisationen nicht existieren. Durch die Entwicklung des Web 2.0 und insbesondere sozialer Medien kommen terroristische Organisationen heutzutage aber ganz ohne das Verschicken von Videotapes an Fernsehsender aus. Durch YouTube und andere Kanäle, können sie die Adressaten ihrer Botschaften direkt und ohne zwischengeschaltete Journalistinnen und Journalisten erreichen. So ist es nicht erstaunlich, dass terroristische Organisationen sich eine gewisse Expertise im Umgang mit sozialen Medien zugelegt haben. Al-Qaida hat seine eigene Medienabteilung, auch die kolumbianischen FARC arbeiten sehr professionell und welchen Einfluss der Islamische Staat im Internet ausübt ist inzwischen bereits Gegenstand einiger Reportagen und Untersuchungen geworden. Die diesem Aufsatz zugrundeliegende Arbeit hat sich mit neun verschiedenen Videos aus dem Umfeld von al-Qaida, der IRA und der FARC beschäftigt und versucht, aus dem analytischen Vergleich dieser Videos Rückschlüsse über terroristische Medienmacher und die terroristischen Organisationen selbst zu ziehen. Wie schnell und suggestiv die Videos arbeiten, ist etwa davon abh

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

  17. Implantate im Mittelohrbereich - Teil 2 (Ergänzungen 2007)

    Science.gov (United States)

    Stieve, M.; Lenarz, Thomas

    In Deutschland leben ca. 12 Millionen Menschen, die an einer ein- oder beidseitigen Schwerhörigkeit leiden. Diese kann angeboren oder im Laufe des Lebens erworben sein. Klinisch und therapeutisch wichtig ist die Unterscheidung hinsichtlich des Schädigungsortes im Bereich des Mittelohres, d. h. eine Schalleitungsschwerhörigkeit, oder im Bereich des Innenohres, d. h. eine Schallempfindungsschwerhörigkeit, wobei hier der Schädigungsort auch am Hörnerven oder in den zentralen Hörabschnitten liegen kann. Therapeutisch lassen sich sowohl Schwerhörigkeiten im Bereich des Mittelohres als auch im Innenohr und sogar im Hirnstammbereich (Hirnstammimplantat) behandeln. 1,9 Millionen Schwerhörige haben eine Erkrankung im Mittelohrbereich, d. h. der Schall kann nur ungenügend auf das Innenohr übertragen werden. Die Ursache besteht meist in einer chronischen Mittelohrentzündung, die zu einer Zerstörung des Trommelfells und der Gehörknöchelchenkette geführt haben. Therapeutisch und damit als Prinzip der operativen Hörverbesserung steht primär der Verschluß des Trommelfells oder eine Rekonstruktion der Gehörknöchelchen. Mittelohroperationen werden mikrochirurgisch unter dem Operationsmikroskop durchgeführt, wobei zunächst durch eine sanierende Operation der Entzündungsprozeß entfernt wird und nach einer Ausheilungszeit die Gehörknöchelchenkette durch künstliche Prothesen rekonstruiert werden kann.

    Science.gov (United States)

    Thyen, Elmar

    Die Energiewende wird ohne eine umfassende Digitalisierung der Energiewirtschaft Stückwerk bleiben. Die historisch gewachsene, aus hunderten fossilen Großkraftwerken getriebene Energieversorgung hat sich durch den Zubau von mehr als einer Millionen dezentraler Erzeugungseinheiten innerhalb der vergangenen 15 Jahren radikal verändert. Zum Ausgleich von Last und Erzeugung, aber auch zum Aufbau neuer Geschäftsfelder ist die digitale Technik unverzichtbar. Ihre Möglichkeiten scheinen nahezu unbegrenzt, ihre Rolle wird in einer zukünftig nahezu vollständig elektrifizierten Gesellschaft zunehmend wichtiger werden. Neue Anbieter drängen auf den Markt und setzen die traditionelle Energiewirtschaft unter Druck. Energieversorger, die sich dem Wandel nicht stellen, drohen den Anschluss zu verpassen. Noch werden Verbundunternehmen und Stadtwerke von weitreichenden regulatorischen Vorgaben geschützt. Beispiele aus anderen Branchen zeigen aber, dass die Digitalisierung im Stande ist, regulatorische Mechanismen außer Kraft zu setzen. Zugleich verhindert die enge Regulierung und ein falsch verstandener Datenschutzbegriff in Deutschland die Entwicklung neuer Geschäftsmodelle, die energie- und volkswirtschaftlich sinnvoll wären.

    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. Dies war zugleich die Voraussetzung für die Bildung kleinerer Siedlungen mit neuen Führungssystemen und Sozialstrukturen sowie mit einem jeweils eigenen Identitätsbewußtsein.

  13. Coherent ambient infrasound recorded by the global IMS network

    Science.gov (United States)

    Matoza, R. S.; Landes, M.; Le Pichon, A.; Ceranna, L.; Brown, D.

    2011-12-01

    The International Monitoring System (IMS) includes a global network of infrasound arrays, which is designed to detect atmospheric nuclear explosions anywhere on the planet. The infrasound network also has potential application in detection of natural hazards such as large volcanic explosions and severe weather. Ambient noise recorded by the network includes incoherent wind noise and coherent infrasound. We present a statistical analysis of coherent infrasound recorded by the IMS network. We have applied broadband (0.01 to 5 Hz) array processing systematically to the multi-year IMS historical dataset (2005-present) using an implementation of the Progressive Multi-Channel Correlation (PMCC) algorithm in log-frequency space. We show that IMS arrays consistently record coherent ambient infrasound across the broad frequency range from 0.01 to 5 Hz when wind-noise levels permit. Multi-year averaging of PMCC detection bulletins emphasizes continuous signals such as oceanic microbaroms, as well as persistent transient signals such as repetitive volcanic, surf, or anthropogenic activity (e.g., mining or industrial activity). While many of these continuous or repetitive signals are of interest in their own right, they may dominate IMS array detection bulletins and obscure or complicate detection of specific signals of interest. The new PMCC detection bulletins have numerous further applications, including in volcano and microbarom studies, and in IMS data quality assessment.

  14. Grundlegende Steuerungsverfahren im heterogenen Logistiknetz mit Kanban

    Science.gov (United States)

    Dickmann, Eva; Dickmann, Philipp; Lödding, Hermann; Möller, Niklas; Rücker, Thomas; Schneider, Herfried M.; Zäh, Michael F.

    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.

  15. 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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Hunka Deborah Elaine; Austin, Daniel E.

    2005-07-01

    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.

  17. Instrumentale Spielformeln und Vokale Verzierungen im 16.Jahrhundert

    Directory of Open Access Journals (Sweden)

    Göllner, Theodor

    2001-12-01

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

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.

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

    Directory of Open Access Journals (Sweden)

    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.

    Kempf, Hans-Georg; Lenarz, Thomas; Eckert, Karl-Ludwig

    In Deutschland leben ungefähr 12 Millionen Menschen, die an einer ein- oder beidseitigen Schwerhörigkeit leiden. Diese kann angeboren oder im Laufe des Lebens erworben sein. Klinisch und therapeutisch wichtig ist die Unterscheidung, ob die Ursache der Schwerhörigkeit im Bereich des Mittelohres, d. h. der Schallübertragung, oder im Bereich des Innenohres, der Hörnerven und der zentralen Hörbahnabschnitte, d. h. der Schallempfindung, liegt. 2,5 Millionen Schwerhörige haben dabei das Problem der Schallübertragung, d.h. die Störung liegt im Mittelohrbereich, und hier kann man in der Regel mit operativen, mikrochirurgisch durchgeführten Massnahmen helfen [1, 2]. Im Vordergrund steht als Ursache hier die chronische Mittelohrentzündung, die sich als Perforation des Trommelfells, als Defekt oder Unterbrechung der Gehörknöchelchen oder auch als Cholesteatom, einer sogenannte Knocheneiterung äussern kann [3]. Therapeutisch und damit als Prinzip der operativen Hörverbesserung steht primär der Verschluss des Trommelfells oder eine Rekonstruktion der Gehörknöchelchen an.

    1997-01-01

    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 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

Diese Arbeitsformen sind auf andere Sprachen übertragbar und aus dem Lehrwerk Mit Deutsch studieren arbeiten leben A2/B1 (Lévy-Hillerich, Serena, Barić & Cickovska 2010 und der dazu gehörenden Lernplattform entnommen. Das Lehrwerk selbst ist eine Umsetzung der SDU-Rahmencurricula, die im Laufe von über zwanzig Jahren in zehn Ländern im Rahmen eines 1994 am Goethe-Institut Warschau begonnenen Hochschulprojekts und der daraus entstandenen Forschungstätigkeit entstanden sind. Grundlage des Projekts ist ein ganzheitlicher soziopädagogischer Ansatz, der LernerInnen als Menschen betrachtet, die im Präsenz- oder im virtuellen Unterricht in der Sprache und durch die Sprache fach- und sprachübergreifende Kooperationsfähigkeiten entwickeln, die sich später im Leben in der Gesellschaft auswirken. Nach der Vorstellung des Projekts und seiner wissenschaftlichen Hintergründe im ersten Teil des Beitrags werden im zweiten Teil die sich aus dem Ansatz ergebenden Arbeitsformen untersucht: Dabei werden die sich dazu eignenden Themen, die Lernhilfen für StudentInnen, die den LehrerInnen zufallenden Rollen sowie die Ansprüche an Lehrbücher/Unterrichtsmaterialien und Online-/Blended-Learning-Lernszenarien besprochen. Der abschließende Überblick im dritten Teil über die Schwierigkeiten, die beim kooperativen Lernen im SDU/SFU auftreten können, ist gleichzeitig eine offenbleibende Frage danach, wie LehrerInnen aus- und fortgebildet werden sollten, um sich den Anforderungen einer sich dauernd verändernden Lernlandschaft stellen zu können.   The paper

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

    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.

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.

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

    Full Text Available Die bildungskulturell leitende Funktion des Buches diffundiert im digitalen Zeitalter mobiler und transversaler Systeme von Netzwerkmedien. Zudem sind soziokulturelle Lebenswelten wie Bildungsinstitutionen, Familie und Peers durch Heterogenität gekennzeichnet. Indem auch diese Teil des Geflechts medienkultureller Architekturen werden, geraten ehemals gültige Unterscheidungsparameter wie explizites und implizites, formelles und informelles Wissen ins Wanken. Grenzziehungen und konkurrierende Auffassungen gegenüber diesen, vormals als der Bildung entgegengesetzt wahrgenommenen, Bereichen erweisen sich nunmehr als problematisch. So spielt Visualität im Kontext multimodal zusammengesetzter Bildungsmaterialien eine zunehmende Rolle und wird als Möglichkeit des Umgangs mit Komplexität eingesetzt. Wenngleich somit die Zurückhaltung gegenüber (Bewegt-Bildmedien in der pädagogischen Praxis schwindet, so haben sich mit der Digitalisierung medienkulturell bedeutsame Felder eröffnet, welche erziehungswissenschaftlicher Beachtung bedürfen. Eine sich der Komplexität digitaler Medienkulturen stellende Medienpädagogik bringt mit sich, dass auch Funktion und Gebrauch visueller Medien im Kontext von Bildungsprozessen reflektiert stattfinden. Medienpädagogisch informiertes Agieren in visuellen Medienkulturen ist darüber hinaus heute gerade deshalb essentiell, da es sich bei digital generierter Visualität um eine neue Qualität im Unterschied zu traditionellen Bildmedien handelt, welche der Logik der Repräsentation entsprachen. Der Beitrag thematisiert Desiderate, die sich hinsichtlich des Visuellen datenbasierter Medien für die Medienpädagogik ergeben, und geht dabei auf kommunikative Bildlichkeit, auf paradigmatische mediale Formen und auf datengestützte Wissensgenerierung ein.

    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

  11. ImBuild: Impact of building energy efficiency programs

    Energy Technology Data Exchange (ETDEWEB)

    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.

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

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

    2016-12-01

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

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

    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

    Crispin Wright hat die bislang beste Rekonstruktion von Putnams Beweis gegen die skeptische Hypothese vom Gehirn im Tank vorgelegt. Aber selbst in Wrights Fassung hat der Beweis einen Mangel: Er wird mithilfe eines Prädikates wie z.B. "Tiger" geführt und funktioniert nur, wenn man sich darauf verlassen kann, dass es Tiger wirklich gibt. Aber die Skeptikerin bestreitet, über die Existenz von Tigern bescheid zu wissen. Das Problem lässt sich dadurch beheben, dass man den Beweis – statt mit dem ...

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

Als Zugang wurde die Technologie der interaktiven Whitebords gewählt, um gegenwärtige Entwicklungen der Digitalisierung von Unterrichtsräumen zu thematisieren und dabei ausgewählte Aspekte von Medienkompetenz zu fördern. In dem Projekt haben verschiedene Einrichtungen der Universität und der Lehrerbildung kooperiert, um eine Multiplikator/-innenschulung für Studierende zu erarbeiten und zu etablieren. Es wurde eine 28-stündige Qualifizierungsreihe entwickelt, die sich aus modularisierten Workshops zur medientechnischen und -didaktischen Auseinandersetzung mit interaktiven Whiteboards, Elementen der Tutor/-innenausbildung sowie der Erarbeitung eines eigenen Unterrichtsentwurfes zusammensetzt. In dem Artikel werden die entwickelten Module vorgestellt und bewertet, inwieweit sie den von Herzig, Aßmann und Klar (2014 formulierten Zielvorstellungen zur Medienkompetenzförderung für das Lehramtsstudium entsprechen. Im Abgleich mit diesen Zielvorstellungen werden Entwicklungspotentiale des Konzepts identifiziert.

    1998-06-01

    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.

Der Essay beginnt mit einer Betrachtung der diskursiven Anwendungen des Konzepts von Aufrichtigkeit zu, um sich anschließend den Filmen dreier junger russischer Regisseurinnen anzunähern: Oksana Byčkovas Eshche odin god / Another Year (2014, Nigina Sajfullaevas Kak menja zovut/ Sag mir, wer ich bin (2014, sowie Natalija Meščaninovas Kombinat „Nadežda“ / Fabrik der Hoffnung (2014. Obwohl sie der sogenannten neuen Welle des Autorenkinos („novaja režisserskaja volna“ zugeordnet werden, fechten die Positionen, die diese Regisseurinnen gegenüber ihren Vorgängern, aber auch ihren Zeitgenossen einnehmen, sowohl in Russland als auch dem Westen eine einfache Zuordnung an. Die Filme bieten einen Einblick in das Anliegen der Regisseurinnen, die gesellschaftlichen und emotionalen Sorgen ihrer Generation auf eine ehrliche und realistische Art und Weise auszudrücken. Eine sorgfältige Untersuchung unterstreicht die unterschiedlich verwendeten, aber dennoch gemeinsamen stilistischen, narrativen und thematischen Elemente, die sie im Film einsetzen. Im Laufe der Untersuchungen begegnet die Aufrichtigkeit nicht nur als diskursives Phänomen, sondern auch als eine vielseitige kulturelle Praxis. Die Mittel, mit denen die einzelnen Filme versuchen bei den Zuschauern eine emotionale Reaktion hervorzurufen, berechtigen die Einordnung einer solchen ästhetischen Taktik als aufrichtig und ehrlich.

    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.

    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)

    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.

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

    Für Güter des täglichen, mittelfristigen und langfristigen Bedarfs sowie für das Beispiel Baumarktartikel wird das Potenzial für Personenverkehrsaufwand von Einkaufsaktivtäten quantitativ abgeschätzt. Die entwickelten Algorithmen behandeln die einkaufsvorbereitende Information und den eigentlichen Einkauf, d.h. den Erwerb eines Gutes, separat. Informationsaktivitäten haben insbesondere bei höherwertigen Gütern einen hohen Stellenwert und damit auch verkehrliche Relevanz. Wie Berechnungen zeigen, spart Online-Shopping Informations- und Einkaufsverkehrsaufwand im Pkw-Verkehr ein. Die notwendigen Eingangsdaten wie differenzierte Informations- und Einkaufshäufigkeiten sowie verkehrliche Parameter zu Verkehrsmittelwahl, Entfernungen und Wegekopplungen wurden aus eigenen Erhebungen gewonnen.

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...... coupling effects and increase robustness against parameters change without requiring any other compensation strategies. The experimental implementation results are provided to demonstrate validity and performance of the proposed control scheme.......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...

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

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

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

    Full Text Available Nachlässe rücken in der wissenschaftlichen Forschung immer mehr in den Fokus, wie etwa die stark gestiegenen Nutzerzahlen der Bayerischen Staatsbibliothek (BSB über die letzten Jahre hinweg deutlich zeigen. Umso wichtiger ist insbesondere für Bibliotheken mit umfangreichen und fachlich breit gestreuten Nachlassbeständen eine möglichst genaue Erschließung im Internet, um der wissenschaftlichen Forschung einen schnellen Zugriff auf diese unikalen Materialien zu ermöglichen. Bei der digitalen Bereitstellung und vernetzten Erschließung verfolgt die BSB mit ihren rund 1.100 Nachlässen eine doppelte Strategie. Einerseits wird versucht, ausgewählte Nachlässe im Verbundsystem Kalliope zu katalogisieren. Andererseits werden die Erschließungsdaten zu den bereits erschlossenen und den erst grob geordneten Nachlässen, die in Form von hand- oder maschinenschriftlichen Listen sowie als Wordlisten vorliegen, digitalisiert und über den Bibliothekskatalog online zur Verfügung gestellt, um den Nutzern die Möglichkeit zu geben, sich so über die vorhandenen Bestände zu informieren. Wie dieses Projekt genau durchgeführt wurde, ist Gegenstand des Artikels. Special collections and personal papers are becoming more and more important for academic research, as is shown clearly by the increasing usage numbers at the Bavarian State Library (BSB over the last couple of years. Especially for libraries with extensive and manifold collections of estates, it is important to present these unique materials in a well-indexed manner on the internet, in order to give the scientific community easy access. The Bavarian State Library, which keeps more than 1.100 estates of personal papers, pursues a double strategy: On the one hand, selected estates are fully cataloged in the database “Kalliope”. As this procedure is likely to take a long time, the library on the other hand has been digitizing older hand- or typewritten lists with information

    Full Text Available Das Deutsche Literaturarchiv Marbach (DLA begann 1998 mit der Evaluation geeigneter Entsäuerungsverfahren für seine unikalen Archiv- und Bibliotheksbestände. Seit 2013 erfolgt eine kontinuierliche Entsäuerungsbehandlung der Buchbestände mit dem Papersave-Verfahren der Nitrochemie AG, mit einer jährlichen Entsäuerungsleistung von insgesamt rund 4,0 t in acht Chargen. Neben den Magazinbeständen mit Erstausgaben bis hin zur Sekundärliteratur zu den einzelnen Autoren, wurden nun auch erstmals erfolgreich Bände aus den Spezialsammlungen des DLA entsäuert, zu denen auch Autorenbibliotheken gehören. Der Beitrag erläutert neben der Zusammenarbeit des Referats Bestandserhaltung mit den Abteilungen Bibliothek und Archiv auch Teilaspekte der Workflows aus restauratorischer Sicht. Dabei steht die intern entwickelte Barcode-unterstützte Dokumentation der Maßnahme auf Exemplarsebene im Bestandskatalog Kallías im Fokus. Sie enthält neben den verfahrensrelevanten Daten u. a. Informationen zu den Ausschlusskriterien oder alternativen und ergänzenden Maßnahmen der Verpackung, Restaurierung oder Digitalisierung. Das Marbacher Mengenentsäuerungsprojekt führt an den Originalen eine Qualitätskontrolle bezüglich aufgetretener Nebenwirkungen am Bibliotheksgut durch und kontrolliert die Langzeitwirkung der Entsäuerung an originalähnlichen Referenzbänden mit nicht zerstörungsfreien Messungen. In 1998 the German Literature Archive (DLA began to evaluate appropriate deacidification processes for its unique archive and library stock.

    2010-07-01

    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.)

    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.

    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.

    2016-12-01

    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.

    Directory of Open Access Journals (Sweden)

    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.

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.

    Full Text Available Dieser Beitrag widmet sich der Frage, inwiefern Cyber-Mobbing unter Bezugnahme auf Judith Butlers sprach- bzw. diskurstheoretisches Konzept als verletzender Sprechakt verstanden werden kann. Zu diesem Zweck werden in einem ersten Schritt die Besonderheiten von Cyber-Mobbing aufgezeigt und im Anschluss daran ein für diesen Text geeigneter Cyber-Mobbing-Begriff formuliert. Daraufhin erfolgt eine interpretative Auseinandersetzung mit der Butlerschen Konzeption verletzender Sprechakte, bevor anschließend anhand wesentlicher Schnittstellen herausgearbeitet wird, inwiefern Cyber-Mobbing als ein solcher verletzender sprachlicher Akt begriffen werden kann. Resümierend werden die zentralen Ergebnisse der Ausarbeitung zusammengefasst und es wird danach gefragt, welche Konsequenzen bzw. Folgen sich hieraus für ein mögliches verändertes Verständnis von Cyber-Mobbing ergeben.This Paper argues whether cyber bullying can be understood as violating speach act with reference to Judith Butler by starting with a definition of cyber bullying (respectively the term cyber 'mobbing' which is used synonymously in German speaking countries and an outline of Butler's theory. After that, the question of a new or different understanding of cyber bullying and its consequences is discussed.

The results are product of the research project "Parental views on children and adolescents playing computer games" of the Faculty of Educational Science of Bielefeld University. The empirical study from 2014 includes 28 qualitative interviews with both parents. The results show among other things that the media-related habitus of parents influences their media-educational habitus. This means e. g. that parents experienced on video games show a more differentiated educational behaviour concerning video games than parents without such kind of experience.

    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.

  17. Respuestas faciales ante imágenes de advertencia de tabaco

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

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

    Science.gov (United States)

    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.

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

    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.

    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.

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

  9. 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.

    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.

    Aurorae are fascinating phenomena. As aurora borealis and aurora australis occurring in the polar regions of both earth hemispheres, their incessant color and shape games put people in wonder. The meteorologist Andreas Pfoser explains the physical connections, which lead to the formation of this natural phenomenon. The link with the activity of the sun and the interaction in the earth atmosphere are explained detailedly and understandably. The fantastic recordings, presented in generous horizontal format has collected the Finnish aurora photographer Tom Eklund over a period of time of 14 years. Thereby it succeeded, to document also some events, the origin of which on our daystar were recorded by solar satellites, so that the sequence of events from the solar eruption until the aurora spectacle can be reproduced. The present 2nd edition contains new scientific findings. Additionally numerous aurora pictures were replaced by more actual photos created with modern technology.

    The harnessing and enhanced use of renewable energy today is a matter of lively debate and much concern. Amazingly, hydro power is either rarely considered in these discussions or viewed in a negative light. But hydro power continues to be the most important source of renewable energy, and its use potential is considerable and should be taken into account when, for instance, agreeing on or implementing carbon dioxide reduction targets. Small hydro power stations are an effective means of harnessing existing energy potentials. (orig.) [Deutsch] Ueber die Nutzung und den Ausbau regenerativer Energien wird heutzutage lebhaft diskutiert und gerungen. Es mag erstaunen, dass in diesen Diskussionen die Wasserkraft kaum Beachtung findet oder in einem schlechten Licht gesehen wird.

    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).

    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.

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

    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.

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

    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.

    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.

  1. Application of Ion Mobility Spectrometry (IMS) in forensic chemistry and toxicology with focus on biological matrices

    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.

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

Based on an analysis of comparable former teaching efforts and giving some disambiguation for the terms interdisciplinarity and multiproessionality, this article describes a teaching project which was designed across the borders of the participating universities. Together students from medical faculty of the university of Freiburg (n=59 and students from the university of applied sciences for social work of Esslingen (n=61 took part in several weekend seminaries, which focussed the topic of interdisciplinary cooperation in the health care and social welfare system. The contribution describes the development of this teaching concept during several years of proving and the design of the evaluation process and instruments, which mainly was based on standardised questionnaires and an additional open discussion. The detailed report about the results of the evaluation and their interpretation do not allow to jump to conclusions concerning the transfer into regular teaching practice. But it gets obvious that students from both faculty claim for the integration of this topic into their education.

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

    Ion mobility spectrometry (IMS) which acts as a rapid analysis technique is widely used in the field detection of illicit drugs and explosives. Due to limited separation abilities of the pint-sized IMS challenges and problems still exist regarding high false positive and false negative responses due to the interference of the matrix. In addition, the gas-phase ion chemistry and special phenomena in the IMS spectra, such one substance showing two peaks, were not identified unambiguously. In order to explain or resolve these questions, in this paper, an ion mobility spectrometry was coupled to a mass spectrometry (IMS-MS). A commercial IMS is embedded in a custom-built ion chamber shell was attached to the mass spectrometer. The faraday plate of IMS was fabricated with a hole for the ions to passing through to the mass spectrometer. The ion transmission efficiency of IMS-MS was optimized by optimizing the various parameters, especially the distance between the faraday plate and the cone of mass spectrum. This design keeps the integrity of the two original instruments and the mass spectrometry still works with multimode ionization source (i.e., IMS-MS, ESI-MS, APCI-MS modes). The illicit drugs and explosive samples were analyzed by the IMS-MS with 63 Ni source. The results showed that the IMS-MS is of high sensitivity. The ionization mechanism of the illicit drug and explosive samples with 63 Ni source were systematically studied. In addition, the interferent which interfered the detection of cocaine was identified as dibutyl phthalate (DBP) by this platform. The reason why the acetone solution of amphetamine showed two peaks was explained. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available The IP multimedia subsystem (IMS is a service control overlay standardized by the 3GPP. 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.

    Full Text Available The IP multimedia subsystem (IMS is a service control overlay standardized by the 3GPP. 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.

    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.

    2012-04-01

    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.

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

    Gaebler, Peter J.; Ceranna, Lars

    2016-04-01

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

  9. A plan for location calibration of IMS stations and near Kazakhstan

    International Nuclear Information System (INIS)

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

    2001-01-01

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

    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.

Bu dönemde, finansal sermaye, kapitalizm içerisinde bir hegemonik lider olarak ön plana çıkmış; devlet, bir yandan üretimin çekirdeğinden uzak bir yerde konumlandırılırken diğer yandan paranın dolaşım kanallarının rehabilitasyonu işine odaklanmış; insana ilişkin değerler, kültürel mefhumlar ve toplumsal pratikler ise birer değişken olarak ekonomi-politikanın merkezine taşınmıştır. Kültür ile ekonomi arasındaki geleneksel ilişki bozulmuş; bir ekonomi-politikanın başarısı, toplumsal aktörlere temas etme kabiliyeti ile paralel hale gelmiştir. 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.

    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

    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.

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

    RELJIC, D.

    2016-11-01

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

    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.

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.

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

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.

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

    Science.gov (United States)

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

    2015-06-01

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

    International Nuclear Information System (INIS)

    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

  17. Concrete loading column for Maureen field built at Loch Kishorn

    The first concrete-built loading column for a North Sea oilfield left the Kyle of Lochalsh under tow on August 18, bound for the Phillips Petroleum Group's Maureen field 163 miles (262 km) eastnortheast of Aberdeen. The 10,000 tonne gravity structure is 430ft (131m) tall and will have cost pounds29 million by the time it is installed offshore. Before starting its 20-day tow behind the tug ''Les Abeilles'', the offshore tankerloading column recently underwent the complex final stages in its construction, involving tow-out from drydock of two concrete sections, their joining by an articulated or hinged joint and then the structure's uprighting in deep water for the fitting of a rotating steel head. The concrete articulated loading column is one of several innovations in the Maureen development programme. The operator, Phillips Petroleum United Kingdom Ltd., and its co-venturers considered that some new approaches were necessary in view of the relatively small size of Maureen's recoverable oil reserves and hence the field's marginal development economics. These innovations included drilling the development wells by semisubmersible drilling rig through a subsea template while the production platform is being built on shore (with a fully completed deck section). Production will commence as soon as the wells are tied back from the subsea template to the platform.

  19. Autophagic cell death: Loch Ness monster or endangered species?

    Science.gov (United States)

    Shen, Han-Ming; Codogno, Patrice

    2011-05-01

    The concept of autophagic cell death was first established based on observations of increased autophagic markers in dying cells. The major limitation of such a morphology-based definition of autophagic cell death is that it fails to establish the functional role of autophagy in the cell death process, and thus contributes to the confusion in the literature regarding the role of autophagy in cell death and cell survival. Here we propose to define autophagic cell death as a modality of non-apoptotic or necrotic programmed cell death in which autophagy serves as a cell death mechanism, upon meeting the following set of criteria: (i) cell death occurs without the involvement of apoptosis; (ii) there is an increase of autophagic flux, and not just an increase of the autophagic markers, in the dying cells; and (iii) suppression of autophagy via both pharmacological inhibitors and genetic approaches is able to rescue or prevent cell death. In light of this new definition, we will discuss some of the common problems and difficulties in the study of autophagic cell death and also revisit some well-reported cases of autophagic cell death, aiming to achieve a better understanding of whether autophagy is a real killer, an accomplice or just an innocent bystander in the course of cell death. At present, the physiological relevance of autophagic cell death is mainly observed in lower eukaryotes and invertebrates such as Dictyostelium discoideum and Drosophila melanogaster. We believe that such a clear definition of autophagic cell death will help us study and understand the physiological or pathological relevance of autophagic cell death in mammals.

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

It means that Islam is a religion which does not only focus on the vertical relation between humans and God but also contains rules of horizontal relation between man and man. Laws with social characteristic lead to the existence of a power as the doer, such as the application of all the punishments and public rewards (al-hudûd wa al-'uqûbât. This article analyzes the thought of Abdullahi Ahmed An--Na’im about syari’ah reformation which is relevant to the constitutionalism standard, criminal law, international law and modern human right, a vision of “syariat modern” which is suitable with the nation state concept which beyond  the offering of the Nation of fundamentalist syariah and the offering of Modern Islamic Nation. The method used by Abdullahi Ahmed An--Na’im is the renewal method which is said as legalized evolution with hermeneutic as the main tool to reach the purpose and normative implication of the text as al-Qur’an. According to Abdullahi Ahmed An--Na’im, the failure of syari’ah application in modern country caused by the crisis on the traditional syari’ah methodology which became its base. Therefore, new syari’ah formulation is needed to be built on the new base. Naskh concept which is initiated by An-Na’im is for answering this crisis.Copyright (c 2016 by Al-Ihkam.

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

    Science.gov (United States)

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

    1993-10-01

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

    The IMS infrasound arrays have up to 15 sites with apertures up to 3 km. They are distributed remarkably uniformly over the globe, providing excellent coverage of South America, Africa, and Antarctica. Therefore, many infrasound arrays are in regions thousands of kilometers from the closest seismic array. Existing 3-component seismic stations, co-located with infrasound arrays, show how typical seismic signals look at these locations. We estimate a theoretical array response assuming a seismo...

  2. Capacity Bounds for the Gaussian IM-DD Optical Multiple-Access Channel

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

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

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

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

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

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

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

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

    The thermal efficiency of subject systems, especially at higher temperatures is influenced by heat and humidity transport underground. Thermal conductivity and specific thermal capacity depend on the humidity content of the soil. A simulation model was developed that describes the coupled heat and humidity transport in the temperature range up to 90 C. This model will be validated in laboratory and field tests and then be used for designing and analysing underground stores. Pilot plants for the storage of industrial waste heat were designed and planned on the basis of this simulation. In both cases these are cogeneration plants whose waste heat was to be used for space heating and as process energy. Both plants have a very high demand of electric energy which is mostly supplied by the cogeneration plant. The waste heat is put into the store during the summer. In the winter heat is supplied by both the store and the cogeneration plant. In both cases the store has a volume of approx. 15,000 cubic metres with 140 and 210 pits located in a depth of 30 and 40 metres. The plants are used to carry out extensive measurements for the validation of simulation models. (orig.) [Deutsch] Die thermische Leistungsfaehigkeit solcher Systeme wird insbesondere im hoeheren Temperaturbereich durch den Waerme- und Feuchtetransport im Untergrund beeinflusst. Sowohl die Waermeleitfaehigkeit als auch die spezifische Waermekapazitaet sind vom Feuchtegehalt des Bodens abhaengig. Es wurde ein Simulationsmodell entwickelt, das den gekoppelten Waerme- und Feuchtetransport im Temperaturbereich bis 90 C beschreibt. Dieses Modell wird an Labor- und Feldexperimenten validiert und dient dann zur Auslegung und Analyse von Erdwaermesonden-Speichern. Basierend auf diesen theoretischen Grundlagenarbeiten wurden Pilotanlagen zur saisonalen Speicherung industrieller Abwaerme ausgelegt und geplant. In beiden Faellen handelt es sich um Kraft/Waermekopplungsanlagen, deren Abwaerme zur Gebaeudeheizung und

In the solid and in solution, the existence of hydrogen bonding between the anionic UCl{sub 6}{sup 2-} complex and the ionic liquid cations were revealed by these techniques. The MeBu{sub 3}N{sup +} cation interacts with UCl{sub 6}{sup 2-} via the protons on the alpha carbon atoms of nitrogen. The protons of the imidazolium ring account for the interaction between the BuMe{sub 2}Im+ cation and the UCl{sub 6}{sup 2-} anion. For the BuMeIm{sup +} cation the major interaction was confirmed between the most acidic proton on C(2) and UCl{sub 6}{sup 2-}. The experimental results also show that the intensity of the interaction between the UCl{sub 6}{sup 2-} anion and the cation varies with the ionic liquid cation in the following order: MeBu{sub 3}N{sup +} {approx} BuMe{sub 2}Im{sup +} << BuMeIm{sup +}.

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

    Das Rhizom von Potentilla officinalis (PO) ist reich an Gerbstoffen und wird traditionell zur äußerlichen Behandlung von Entzündungen der Haut und der Schleimhäute verwendet. Ziel der vorliegenden Arbeit war die Bestätigung der antiinflammatorischen Eigenschaften von PO mittels eines UV-Erythem-Tests und einer klinischen Anwendungsstudie bei atopischer Haut. Die antiinflammatorische Wirkung eines PO-Extrakts (standardisiert auf 2 % Trockensubstanz) wurde in einer prospektiven, randomisierten, placebokontrollierten Doppelblindstudie mit 40 gesunden Erwachsenen im UV-Erythem-Test im Vergleich zu 1 % Hydrocortisonacetat untersucht. Im Rahmen einer prospektiven nicht kontrollierten Studie wurde die Wirkung und Verträglichkeit der 2 % PO-Creme an zwölf Erwachsenen und zwölf Kindern mit atopischer Haut nach Anwendung über zwei Wochen in einem definierten Testareal anhand eines Teil-SCORAD untersucht. Zusätzlich wurde die Beeinflussung der Hautrötung im Testareal photometrisch gemessen. Im UV-Erythem-Test zeigte die PO-Creme eine signifikante Reduktion des Erythemindex im Vergleich zum Vehikel. Die antiinflammatorische Wirkung des Verums entsprach der der 1 % Hydrocortisonacetat-Creme. Die klinische Studie bei Atopikern zeigte eine signifikante Abnahme des Teil-SCORAD und des Erythems im Testareal. Es wurden keine Unverträglichkeitsreaktionen beobachtet. PO als 2%ige Zubereitung besitzt entzündungshemmende Eigenschaften und ist wirksam und gut verträglich auf atopischer Haut. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

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

    Bartok, J.

    2010-01-01

    The dissertation presents IMS Lagrangian Dispersion Model, which is a 'new generation' Slovak dispersion model of long-range transport, developed by MicroStep-MIS. It solves trajectory equation for a vast number of Lagrangian 'particles' and stochastic equation that simulates the effects of turbulence. Model contains simulation of radioactive decay (full decay chains of more than 300 nuclides), and dry and wet deposition. Model was integrated into IMS Model Suite, a system in which several models and modules can run and cooperate, e.g. LAM model WRF preparing fine resolution meteorological data for dispersion. The main theme of the work is validation of dispersion model against large scale international campaigns CAPTEX and ETEX, which are two of the largest tracer experiments. Validation addressed treatment of missing data, data interpolation into comparable temporal and spatial representation. The best model results were observed for ETEX I, standard results for CAPTEXes and worst results for ETEX II, known in modelling community for its meteorological conditions that can be hardly resolved by models. The IMS Lagrangian Dispersion Model was identified as capable long range dispersion model for slowly- or nonreacting chemicals and radioactive matter. Influence of input data on simulation quality is discussed within the work. Additional modules were prepared according to praxis requirement: a) Recalculation of concentrations of radioactive pollutant into effective doses form inhalation, immersion in the plume and deposition. b) Dispersion of mineral dust was added and tested in desert locality, where wind and soil moisture were firstly analysed and forecast by WRF. The result was qualitatively verified in case study against satellite observations. (author)

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

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

    Blasting technique with electric detonators is a standard instrument e.g. for drift heading in underground coal mining. The simultaneous increase of compactness and efficiency of electrical devices especially in underground mining calls for a careful consideration of susceptibility problems. As an interference of an inadmissible high level might cause a hazardous ignition limiting values and technical parameters of interference to electrical blasting circuits are evaluated. The sources of interference are classified into communication and power technique devices. Typical interference field strengths are determined by exemplary measurements and a model of wave propagation in underground galleries. An equivalent circuit of the impedance of typical electro-explosive devices used in German coal mining is evaluated and extended by an electro-thermal part based on the `Rosenthal equation`. By this means it is possible to determine a feasible ignition during a simulation using the calculated bridge wire temperature. (orig.) [Deutsch] Fuer den untertaegigen Steinkohlenbergbau ist die Sprengtechnik sowohl im Bereich der Streckenauffahrung als auch beim Schachtabteufen heute noch ein wichtiges Arbeitsinstrument.

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

    2017-11-01

    This article is a discursive examination of children's status as knowledgeable moral agents within the Swedish child welfare system and in the widely used assessment framework BBIC. Departing from Fricker's concept of epistemic injustice, three discursive positions of children's moral status are identified: amoral, im/moral and dis/loyal. The findings show the undoubtedly moral child as largely missing and children's agency as diminished, deviant or rendered ambiguous. Epistemic injustice applies particularly to disadvantaged children with difficult experiences who run the risk of being othered, or positioned as reproducing or accommodating to the very same social problems they may be victimised by.

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

    Science.gov (United States)

    Bellavista, Paolo; Corradi, Antonio; Foschini, Luca

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

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

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

    2013-01-01

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

    The Information Management Toolkit (ImTK) Consortium is an open source initiative to develop robust, freely available tools related to the information management needs of basic, clinical, and translational research. An open source framework and agile programming methodology can enable distributed software development while an open architecture will encourage interoperability across different environments. The ISIS Center has conceptualized a prototype data sharing network that simulates a multi-center environment based on a federated data access model. This model includes the development of software tools to enable efficient exchange, sharing, management, and analysis of multimedia medical information such as clinical information, images, and bioinformatics data from multiple data sources. The envisioned ImTK data environment will include an open architecture and data model implementation that complies with existing standards such as Digital Imaging and Communications (DICOM), Health Level 7 (HL7), and the technical framework and workflow defined by the Integrating the Healthcare Enterprise (IHE) Information Technology Infrastructure initiative, mainly the Cross Enterprise Document Sharing (XDS) specifications.

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

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

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

Grundlage dafür ist eine Operationalisierung des Identitätsbegriffs im Anschluss an die neuere Netzwerktheorie um Harrison C. WHITE. Identitäten folgen aus relationalen Positionierungen, die lokal, typisiert, laufbahnbezogen oder personalisiert vollzogen werden können. Narrative Interviews zeichnen sich dadurch aus, dass in ihnen die lokal-interaktive Identitätskonstruktion der Biograf/innen wesentlich über die Entfaltung einer big story (d.h. einer personalen Identität geschieht. Anhand eines Textbeispiels wird gezeigt, dass sich solche autobiografischen Erzählungen aus einer Vielzahl von kleinen Storys zusammensetzen, in denen identitäre Positionierungen auf unterschiedlichen Identitätsebenen vorgenommen werden. Die Debatte um small stories und big stories einerseits und der Whitesche Theorieansatz andererseits können voneinander profitieren. Für das Identitätsmodell der relationalen Soziologie stellen autobiografische Interviews eine wichtige, bislang wenig genutzte Informationsquelle dar.

    MALDI imaging mass spectrometry is a highly sensitive and selective tool used to visualize biomolecules in tissue. However, identification of detected proteins remains a difficult task. Indirect identification strategies have been limited by insufficient mass accuracy to confidently link ion images to proteomics data. Here, we demonstrate the capabilities of MALDI FTICR MS for imaging intact proteins. MALDI FTICR IMS provides an unprecedented combination of mass resolving power (~75,000 at m/z 5000) and accuracy (differentiate a series of oxidation products of S100A8 ( m/z 10,164.03, -2.1ppm), a subunit of the heterodimer calprotectin, in kidney tissue from mice infected with Staphylococcus aureus.

    Pickup ion detection at Titan is challenging because ion cyclotron waves are rarely detected in the vicinity of the moon. In this work, signatures left by freshly produced pickup heavy ions (m/q ˜ 16 to m/q ˜ 28) as detected in the plasma data by the Cassini Plasma Spectrometer/Ion Mass Spectrometer (CAPS/IMS) instrument on board Cassini are analyzed. In order to discern whether these correspond to ions of exospheric origin, one of the flybys during which the reported signatures were observed is investigated in detail. For this purpose, ion composition data from time-of-flight measurements and test particle simulations to constrain the ions' origin are used. After being validated, the detection method is applied to all the flybys for which the CAPS/IMS instrument gathered valid data, constraining the region around the moon where the signatures are observed. The results reveal an escape region located in the anti-Saturn direction as expected from the nominal corotation electric field direction. These findings provide new constraints for the area of freshly produced pickup ion escape, giving an approximate escape rate of 3.3-2+3×1023 ions· s-1.

Dabei wird von der spracherwerbstheoretisch hergeleiteten Annahme ausgegangen, dass Förderangebote entwicklungssensitiv angelegt sein sollten, also von der erwartbaren Erwerbsprogression und dem jeweiligen Sprachstand des Kindes ausgehen sollten. Mit dieser diagnostischen Zielsetzung vor Augen werden anhand der Kategorien „entwicklungspsychologische/schulische Relevanz“, „profilanalytische Auswertung“ sowie „Authentizität der Sprachdaten“ Anforderungen an ein förderdiagnostisches Verfahren formuliert und exemplarisch auf Erkenntnisse der Spracherwerbsforschung zurückbezogen. The present article addresses the question of which characteristics a language proficiency assessment of children ́s narrative competence should possess to allow for its results to be used for planning subsequent assistance measures.The underlying assumption states that language acquisition processes follow their own inherent developmental pathway. Language promotion programmes should therefore be responsive to the children's development and be based on the respective proficiency level and the learning progress that may be expected. In view of this objective, the article specifies requirements on „interventional diagnostics” and correlates these with insights from languageacquisition research.
