    The project started in 2008 as a sound installation, a collaboration between an artist, a barrel organ builder and a seismologist. The work differs from other attempts of sound transposition of seismic records. In this case seismic frequencies are not converted automatically into the "sound of the earthquake." However, it has been studied a musical translation system that, based on the organ tonal scale, generates a totally unexpected sequence of sounds which is intended to evoke the emotions aroused by the earthquake. The symphonies proposed in the project have somewhat peculiar origins: they in fact come to life from the translation of graphic tracks into a sound track. The graphic tracks in question are made up by copies of seismograms recorded during some earthquakes that have taken place around the world. Seismograms are translated into music by a sculpture-instrument, half a seismograph and half a barrel organ. The organ plays through holes practiced on paper. Adapting the documents to the instrument score, holes have been drilled on the waves' peaks. The organ covers about three tonal scales, starting from heavy and deep sounds it reaches up to high and jarring notes. The translation of the seismic records is based on a criterion that does match the highest sounds to larger amplitudes with lower ones to minors. Translating the seismogram in the organ score, the larger the amplitude of recorded waves, the more the seismogram covers the full tonal scale played by the barrel organ and the notes arouse an intense emotional response in the listener. Elisa Strinna's Seismic Symphonies installation becomes an unprecedented tool for emotional involvement, through which can be revived the memory of the greatest disasters of over a century of seismic history of the Earth. A bridge between art and science. Seismic Symphonies is also a symbolic inversion: the instrument of the organ is most commonly used in churches, and its sounds are derived from the heavens and

    The audiograms of fifty-seven musicians from four Danish symphony orchestras were determined. The fifty-seven persons (26 females and 31 males) were in the age range from 22 to 65 years. The subjects were interviewed and participated voluntarily in the investigation.Measurements of sound level were...... performed during rehearsal and during concerts in the four orchestras with a sound level meter placed in various instrument groups. At the same time a noise dose meter was used to evaluate the dose perceived by specific orchestra members.The average audiogram showed a decrease at higher frequencies similar...... that musicians cannot be expected to get pronounced hearing losses from playing in a symphony orchestra. It should be noted, though, that the data material is limited, and that the subjects have not been selected in a systematical or representative way....

  4. Cylinder supplied ammonia scrubber testing in IDMS

    International Nuclear Information System (INIS)

    This report summarizes the results of the off-line testing the Integrated DWPF Melter System (IDMS) ammonia scrubbers using ammonia supplied from cylinders. Three additional tests with ammonia are planned to verify the data collected during off-line testing. Operation of the ammonia scrubber during IDMS SRAT and SME processing will be completed during the next IDMS run. The Sludge Receipt and Adjustment Tank (SRAT) and Slurry Mix Evaporator (SME) scrubbers were successful in removing ammonia from the vapor stream to achieve ammonia vapor concentrations far below the 10 ppM vapor exit design basis. In most of the tests, the ammonia concentration in the vapor exit was lower than the detection limit of the analyzers so results are generally reported as <0.05 parts per million (ppM). During SRAT scrubber testing, the ammonia concentration was no higher than 2 ppM and during SME testing the ammonia concentration was no higher than 0.05 m

    Full Text Available Discoloration of composite resins is considered to be a major factor in esthetic restoration"nfailures. The aim of this study was to evaluate color stability of IDM composite (both light and self cure"nsamples namely IL and IS, and to compare it with a self-cure composite (Degufill named DS and a light"ncure ormocer composite (Definite, called DL in the Report. 60 disk shaped samples of each composite"nwere prepared, according to ISO-7491. The samples were divided into 3 groups and aged as follows:"nA- (Control 7 days in dark 37°c chamber"nB- Foil covered and kept in 100% humidity, and 37°c in xenotest chamber for 24 hours, then transferred"nto a dark 37°c chamber for 6 more days."nC- Kept in 37°c, 100% humidity under the emission of xiiion lamp of xenotest chamber for 24 hours,"nand then transferred to 37°c dark chamber for 6 more days"nThe lightness and chromaticity values of samples were measured both before and after aging using a"nspectrophotometer (Data Flash. The total color changes as well as changes in lightness and chromaticity"nvalues were measured in the CIE L * a * b * scale, and analyzed. Color change was recorded to be"nsignificant in all samples after aging. The maximum change belonged to IL, which was significantly"ndifferent from DL and DS. It seems, in order to have a durable esthetic restoration using IDM, more"nscientific and professional consideration is needed in the production process.

  7. Efficiency of TTAC's ORTEC IDM

    Energy Technology Data Exchange (ETDEWEB)

    Livesay, Jake [ORNL; Combs, Jason C [ORNL; Margrave, Timothy E [ORNL; Miller, Ian J [ORNL

    2012-08-01

    ORNL's Technical Testing and Analysis Center (TTAC) acquired a High Purity Germanium Detector (HPGe) from ORTEC - a variant called an Interchangeable Detection Module (IDM). This detector has excellent energy resolution as well as high intrinsic efficiency. The purpose of this report is to detail the determination of the efficiency curve of the IDM, so future measurements can quantify the (otherwise unknown) activity of sources. Without such a curve, the activity cannot be directly reported by use of the IDM alone - a separate device such as an ion chamber would be required. This builds upon the capability of TTAC. The method for determining the energy-dependent intrinsic efficiency is laid-out in this report. It's noteworthy that this basic technique can be applied to any spectroscopic radiation detector, independent of the specific type (e.g. NaI, CzT, ClYC).

    We study an extension of the inert doublet model (IDM) that includes an extra complex singlet of the scalars fields, which we call the IDMS. In this model there are three Higgs particles, among them a SM-like Higgs particle, and the lightest neutral scalar, from the inert sector, remains a viable dark matter (DM) candidate. We assume a non-zero complex vacuum expectation value for the singlet, so that the visible sector can introduce extra sources of CP violation. We construct the scalar potential of IDMS, assuming an exact Z 2 symmetry, with the new singlet being Z 2-even, as well as a softly broken U(1) symmetry, which allows a reduced number of free parameters in the potential. In this paper we explore the foundations of the model, in particular the masses and interactions of scalar particles for a few benchmark scenarios. Constraints from collider physics, in particular from the Higgs signal observed at the Large Hadron Collider with {M}h≈ 125 {{GeV}}, as well as constraints from the DM experiments, such as relic density measurements and direct detection limits, are included in the analysis. We observe significant differences with respect to the IDM in relic density values from additional annihilation channels, interference and resonance effects due to the extended Higgs sector.

  11. Entitlement Management: Ready to Enter the IdM Mainstream

    Science.gov (United States)

    Gebel, Gerry; Wang, Alice

    Externalizing authorization processing from business applications has been a goal for architects and developers for many years. Recent compliance demands for more granular access control and policy transparency have increased the urgency to adopt an architectural model where authorization and entitlement management are consumed as a service rather than embedded within business applications. Major software vendors, such as Microsoft, Oracle, and SAP, are making significant steps to separate IdM functionality, including entitlement management from application logic. The market has also responded with a plethora of products that provide entitlement management and authorization functionality for commercial or custom-built application environments. Finally, the Extensible Access Control Markup Language (XACML) has emerged as the consensus authorization standard being supported by a growing number of IT and application vendors. Collectively, these forces form the basis of a nascent IdM market segment referred to as entitlement management.

    equipment placed in various instrument groups. The average audiogram showed a decrease at higher frequencies similar to an age-related hearing loss. Each audiogram was corrected for the age of the person by means of the median from ISO 7029 and the average audiogram from these age-corrected individual...... audiograms showed no signs of hearing loss. The audiograms were also compared to the expected audiograms from ISO 1999, which takes account of the number of years at work, the number of playing hours per week, and the average sound level in the orchestra for the instrument group. In almost all cases...... the measured audiograms looked better than the predictions from ISO 1999. It may be concluded from this investigation that musicians cannot be expected to get pronounced audiometric hearing losses from playing in a symphony orchestra. It should be noted, though, that the data material is limited...

    1993-01-01

    The Internal Discharge Monitor (IDM) is designed to observe electrical pulses from common electrical insulators in space service. The characteristics of the instrument are described. The IDM was flown on the Combined Release and Radiation Effects Satellite (CRRES). The sixteen insulator samples included G10 circuit boards, FR4 and PTFE fiberglass circuit boards, FEP Teflon, alumina, and wires with common insulations. The samples are fully enclosed, mutually isolated, and space radiation penetrates 0.02 cm of aluminum before striking the samples. Published data in the literature provides a simple method for determining the flux of penetrating electrons. The pulse rate is compared to the penetrating flux of electrons.

  20. Accurate quantification of total chromium and its speciation form Cr(VI) in water by ICP-DRC-IDMS and HPLC/ICP-DRC-IDMS.

    Science.gov (United States)

    2016-05-15

    Two analytical procedures have been developed for the determination of total chromium (TCr) and its highly toxic species, i.e. Cr(VI) in water samples using the following methods: inductively coupled plasma dynamic reaction cell isotope dilution mass spectrometry (ICP-DRC-IDMS) and high performance liquid chromatography inductively coupled plasma dynamic reaction cell isotope dilution mass spectrometry (HPLC/ICP-DRC-IDMS). Spectral interferences, predominantly occurring in chromium determination, were removed using a dynamic reaction cell (DRC). The presented procedures facilitate the quantification of trace amounts - below 1 µg L(-1) of TCr and individual Cr species - in various water matrices including drinking water and still bottled water with different mineral composition. Special attention has been paid to the adequate preparation of isotopically enriched (53)Cr(VI) standard solution in order to avoid artifacts in chromium speciation. Both procedures were fully validated as well as establishing the traceability and estimation of the uncertainty of measurement were carried out. Application of all of the above mentioned elements and of the isotope dilution technique, which provides the highest quality of metrological traceability, allowed to obtain reliable and high quality results of chromium determination in water samples. Additionally, the comparison of two methods: HPLC/ICP-DRC-MS and HPLC/ICP-DRC-IDMS for Cr(VI) determination, was submitted basing on the validation parameters. As a result, the lower values for these parameters were obtained using the second method. PMID:26992546

  1. IDM as a "Minor" Literature: The Treatment of Cultural and Musical Norms by "Intelligent Dance Music"

    Directory of Open Access Journals (Sweden)

    Ramzy Alwakeel

    2009-09-01

    Full Text Available This piece opens with a consideration of the etymology and application of the term “IDM”, before examining the treatment of normative standards by the work associated therewith. Three areas in particular will be focused upon: identity, tradition, and morphology. The discussion will be illuminated by three case studies, the first of which will consider Warp Records’ relationship to narrative; the two remaining will explore the work of Autechre and Aphex Twin with some reference to the areas outlined above. The writing of Deleuze and Guattari will inform the ideas presented, with particular focus being made upon the notions of “minority”, “deterritorialisation”, and “continuous variation”. Based upon the interaction of the wider IDM “text” with existing “constants”, and its treatment of itself, the present work will conclude with the suggestion that IDM be read as a “minor” literature.

  2. The Pulsar Quartet: Listening to a Galactic Symphony

    2014-06-01

    Pulsars are exotic dead stars that emit very regular radio pulses. These pulses are attributed to their regular rotation. Some pulsars are spinning fast enough that the audio equivalent waveform of their pulses fall within our hearing range. If human ears were tuned to radio waves it would have been possible to ‘hear’ these very compact stars. We produced the audio waveform of these pulsar signals and mapped them onto a frequency chart to find the corresponding musical notes. We use these ‘audible' pulsars like musical instruments in a symphony orchestra to play a full quartet. At the same time, an accompanying visual interface shows the realistic distribution of all pulsars in our own Galaxy. Pulsars shine as they play each note in the quartet with realistic brightening and subsequent dimming proportional to their rotational energies. This can serve as an educational tool at all levels to demonstrate many interesting aspects of stellar evolution and articulate an aesthetic connection of us with the cosmos. Interested in watching the light show while the Milky Way Pulsar Orchestra plays a quartet?

  3. Noise-induced hearing loss and symphony orchestra musicians: risk factors, effects, and management.

    1998-01-01

    Although industrial and recreational noise have been recognized as potential causes of noise-induced hearing loss for quite some time, it is only recently that the sound levels within a symphony orchestra have been implicated as possible sources of harmful noise levels. Many studies have concluded that not only are dangerous levels of noise present within the symphony orchestra, but there is evidence of noise-induced hearing loss among symphony orchestra musicians. Although hearing protection designed for industrial use may not be appropriate for the special listening needs of professional musicians, recent advances in hearing protection design have made hearing protection practical for this population. Suggestions are made for monitoring and protecting the professional ear.

    Vitrification facilities are being developed worldwide to convert high-level nuclear waste to a durable glass form for permanent disposal. Facilities in the United States include the Department of Energy`s Defense Waste Processing Facility (DWPF) at the Savannah River Site, the Hanford Waste Vitrification Plant (HWVP) at the Hanford Site and the West Valley Demonstration Project (WVDP) at West Valley, NY. At each of these sites, highly radioactive defense waste will be vitrified to a stable borosilicate glass. The DWPF and WVDP are near physical completion while the HWVP is in the design phase. The Integrated DWPF Melter System (IDMS) is a vitrification test facility at the Savannah River Technology Center (SRTC). It was designed and constructed to provide an engineering-scale representation of the DWPF melter and its associated feed preparation and off-gas treatment systems. Because of the similarities of the DWPF and HWVP processes, the IDMS facility has also been used to characterize the processing behavior of a reference NCAW simulant. The demonstration was undertaken specifically to determine material balances, to characterize the evolution of offgas products (especially hydrogen), to determine the effects of noble metals, and to obtain general HWVP design data. The campaign was conducted from November, 1991 to February, 1992.

    Einstein's Symphony: A Gravitational Wave Voyage Through Space and Time is a gravitational wave astronomy planetarium show in production by a collaboration of scientists, filmmakers, and artisits from the Center for Gravitational Wave Astonomy (CGWA) at the University of Texas at Brownsville (UTB) and Montana State University (MSU). The project builds on the success of the interdisciplinary Celebrating Einstein collaboration. The artists and scientists who created the A Shout Across Time original film and the Black (W)hole immersive art installation for Celebrating Einstein are teaming with the Museum of the Rockies Taylor Planetarium staff and students to create a new full dome Digistar planetarium show that will be freely and widely distributed to planetaria in the US and abroad. The show uses images and animations filmed and collected for A Shout Across Time and for Black (W)hole as well as new images and animations and a new soundtrack composed and produced by the MSU School of Music to use the full capability of planetarium sound systems. The planetarium show will be narrated with ideas drawn from the Celebrating Einstein danced lecture on gravitational waves that the collaboration produced. The combination of products, resources, and team members assembled for this project allows us to create an original planetarium show for a fraction of the cost of a typical show. In addition, STEM education materials for G6-12 students and teachers will be provided to complement and support the show. This project is supported by the Texas Space Grant Consortium (TSGC), Montana Space Grant Consortium (MSGC), and the American Physical Society (APS).

  10. IDMS studies on sodalite - a candidate material for nuclear waste containment

    International Nuclear Information System (INIS)

    Nuclear waste management is one of the important aspects of nuclear fuel cycle from environmental and safety considerations. Different forms of waste storage matrices are known to be applicable for different kinds of nuclear wastes. Glass bonded sodalite (GBS) (Na8(AISiO4)6Cl2), a glass-ceramic, is a promising candidate for the immobilization of the chloride waste resulting from pyrometallurgical reprocessing of nuclear fuels. Characterization of individual components is essential for the development of this waste storage material which is expected to encounter different physicochemical conditions. For this purpose, we have undertaken studies to determine the concentrations of individual components in GBS employing Isotope Dilution Mass Spectrometry (IDMS) owing to its capability to ensure precise and accurate data for multi element analysis in a matrix

    Full Text Available Feedforward controller would be useful for hybrid Functional Electrical Stimulation (FES system using powered orthotic devices. In this paper, Feedback Error Learning (FEL controller for FES (FEL-FES controller was examined using an inverse statics model (ISM with an inverse dynamics model (IDM to realize a feedforward FES controller. For FES application, the ISM was tested in learning off line using training data obtained by PID control of very slow movements. Computer simulation tests in controlling wrist joint movements showed that the ISM performed properly in positioning task and that IDM learning was improved by using the ISM showing increase of output power ratio of the feedforward controller. The simple ISM learning method and the FEL-FES controller using the ISM would be useful in controlling the musculoskeletal system that has nonlinear characteristics to electrical stimulation and therefore is expected to be useful in applying to hybrid FES system using powered orthotic device.

    Integration of the priming effect (PE) in ecosystem models is crucial to better predict the consequences of global change on ecosystem carbon (C) dynamics and its feedbacks on climate. Over the last decade, many attempts have been made to model PE in soil. However, PE has not yet been incorporated into any ecosystem models. Here, we build plant/soil models to explore how PE and microbial diversity influence soil/plant interactions and ecosystem C and nitrogen (N) dynamics in response to global change (elevated CO2 and atmospheric N depositions). Our results show that plant persistence, soil organic matter (SOM) accumulation, and low N leaching in undisturbed ecosystems relies on a fine adjustment of microbial N mineralization to plant N uptake. This adjustment can be modeled in the SYMPHONY model by considering the destruction of SOM through PE, and the interactions between two microbial functional groups: SOM decomposers and SOM builders. After estimation of parameters, SYMPHONY provided realistic predictions on forage production, soil C storage and N leaching for a permanent grassland. Consistent with recent observations, SYMPHONY predicted a CO2 -induced modification of soil microbial communities leading to an intensification of SOM mineralization and a decrease in the soil C stock. SYMPHONY also indicated that atmospheric N deposition may promote SOM accumulation via changes in the structure and metabolic activities of microbial communities. Collectively, these results suggest that the PE and functional role of microbial diversity may be incorporated in ecosystem models with a few additional parameters, improving accuracy of predictions.

    This article analyzes the determinants of innovation and success of innovation in the field of U.S. symphony orchestras from 1879 through 1959: why did major orchestras (N = 27) innovate by introducing works of new composers to the repertoire instead of sticking to canonical pieces? Can organizational processes account for the selection and the…

  15. Determination of heavy metals (Pd, Cd, Cu, Zn, Cr) in sedimentary reference materials with IDMS: Total concentration and aqua regia soluble portion

    The total concentration and the aqua regia soluble portion of traces of Pb, Cd, Cu, Zn, and Cr are determined with isotope dilution mass spectrometry (IDMS) in three different types of sediments using a thermal quadrupole instrument (THQ). The results are compared with those obtained by other methods during a certification project to establish these sediments (BCR 277, BCR 280, BCR 320) as standard reference materials. The IDMS (THQ) results are in good agreement with the preliminary certification values and the results of two other laboratories, which applied IDMS using magnetic sector field mass spectrometers. Significant differences between the different analytical methods were found for the total Pb concentration, which could be explained by adsorption and coprecipitation effects during the chemical pretreatment of samples. Using aqua regia instead of HF/HNO/sub 3/ for the decomposition of sediments, only 65%-95% of the total Pb and 60%-90% of the total Cr could be dissolved. On the other hand, only a small or negligible portion of Zn, Cd, and Cu could not be dissolved by aqua regia. The IDMS values for the aqua regia soluble Cr portion are significantly higher compared to the results of other methods. This can be explained by adsorption effects.

  18. Expression Surpassing Words: Gorecki’s Symphony No. 3, Op. 36 “Sorrowful Songs”

    Directory of Open Access Journals (Sweden)

    Full Text Available The experience of listening to Gorecki’s Symphony no. 3, op. 36 “Sorrowful Songs” is one that is not easily forgotten. It is not only musically captivating, but also historically fascinating. After its premiere in 1977, Gorecki’s piece captivated listeners across the globe as it became a cultural phenomenon in both Europe and America. The music was a stunning success in both the Classical and popular cultures. What is it about the music that is so captivating? How did the trending, popular thoughts compare to Gorecki’s original ideas and compositional motives? What actually inspired this piece? By looking at the composition and premise of each movement, I am going to introduce how the piece was written around the theme of maternal love and separation of mother and child. The Third Symphony was heavily influenced by Gorecki’s personal past, but also by his Catholic beliefs and by Polish history. The separate texts to this three movement piece deal individually with a mother’s lament over her son’s departure, the Virgin Mary’s grief at her Son’s death, and finally the words of an incarcerated prison girl to her mother. Because of the setting from which the third text was drawn, and because of Gorecki’s Polish history and experiences in the post-holocaust world, many people have interpreted this to be a “war piece” which avenges the sufferers of the Holocaust. According to Gorecki, this piece is a lament- it expresses a profound sense of grief which, arguably, cannot accurately be expressed with words. Gorecki used his music to confront, mourn, and express his pain and the pain of many other people. By finding primary sources, such as interviews of Henryk Gorecki, and by looking at the scholarly books and journals by Luke B. Howard, Adrian Thomas, and other scholars of Polish avant-garde music, I hope to properly understand and express the intentions Gorecki wished to convey by writing The Symphony of Sorrowful Songs.

  19. Transfinite harmonization by taking the dissonance out of the quantum field symphony

    International Nuclear Information System (INIS)

    Particle physics may be likened to a magnificent symphony. Alas due to some instrumental defects, wrong reading of the notes and a lack of virtuosity of some members of the orchestra, a non-negligible number of dissonants are making it sound less than perfect. By means of the specific example of renormalization groups applied to GUT unification, the present work aims at illustrating the point we just made and showing how a simplictic transfinite adjustment of our formulas lead to harmonization and consequently considerable simplification of well known theories which goes as far as facilitating the discovery of new connections and the solution of many problems which were previously thought very hard, if at all possible, to solve

    A new generation of observatories, now being completed worldwide, will give astronomers not just a new window on the cosmos but a whole new sense with which to explore and experience the heavens above us. Instead of collecting light waves or radio waves, these novel instruments will allow astronomers to at last place their hands upon the fabric of space-time and feel the very rhythms of the universe. These vibrations in space-time-or gravity waves-are the last prediction of Einstein's general theory of relativity yet to be observed directly. They are his unfinished symphony, waiting nearly a century to be heard. When they finally reveal themselves to astronomers, we will for the first time be able to hear the cymbal crashes from exploding stars, tune in to the periodic drumbeats from swiftly rotating pulsars, listen to the extended chirps from the merger of two black holes, and eavesdrop on the remnant echoes from the mighty jolt of the Big Bang itself. When Einstein introduced general relativity in 1915, it ...

    B compared with the 238 ears with lowest exposure. The observed hearing loss of musicians was smaller compared with the noise-induced permanent threshold shift (NIPTS) predicted from ISO1999. A remaining confounding effect of age after ISO7029 age corrections could be observed to explain the difference...... in observed and predicted NIPTS. However, the observed hearing loss difference between the left and the right ear of musicians was 2.5 dB (95% confidence interval 1.5-3.6), which was similar to the NIPTS predicted from ISO1999. Most of the musicians had better hearing at 3, 4, and 6 kHz for age than expected...... of the symphony orchestra musicians had better hearing than expected but they had a work-related risk of developing additional noise-induced hearing loss. The additional NITPS of the left ear compared with the right ear was at the expected level based on the cumulated sound exposure and ISO1999, indicating...

    Full Text Available Abstract Background Histologic samples all funnel through the H&E microtomy staining area. Here manual processes intersect with semi-automated processes creating a bottleneck. We compare alternate work processes in anatomic pathology primarily in the H&E staining work cell. Methods We established a baseline measure of H&E process impact on personnel, information management and sample flow from historical workload and production data and direct observation. We compared this to performance after implementing initial Lean process modifications, including workstation reorganization, equipment relocation and workflow levelling, and the Ventana Symphony stainer to assess the impact on productivity in the H&E staining work cell. Results Average time from gross station to assembled case decreased by 2.9 hours (12%. Total process turnaround time (TAT exclusive of processor schedule changes decreased 48 minutes/case (4%. Mean quarterly productivity increased 8.5% with the new methods. Process redesign reduced the number of manual steps from 219 to 182, a 17% reduction. Specimen travel distance was reduced from 773 ft/case to 395 ft/case (49% overall, and from 92 to 53 ft/case in the H&E cell (42% improvement. Conclusions Implementation of Lean methods in the H&E work cell of histology can result in improved productivity, improved through-put and case availability parameters including TAT.

  3. New age in Serbia, Zoran Simjanović: New ideas symphony

    Full Text Available ′New age′ was a trend which appeared in the music of the 1980’s, bringing a new dimension to art music in general, especially in its reception. At first its development was stimulated by technological inventions, ′the technological craze′, by new carriers of sound, simultaneously globalizing art and making it widely accessible. This new trend includes quite disparate categories. It does not distance itself from subculture, and in art music it gravitates towards cosmopolitism while being permeated with other musical trends such as pop, rock, jazz and other phenomena of show business and popular art. This trend was originally found in the large number of occult writing which flooded book markets all over the world, to which Umberto Eco gave an important base (Foucault's Pendulum and others. In his essay on the music of the eighties, Peter Niklas Wilson, one of the most significant theoreticians of this movement, researches into all elements of those novelties, not hesitating to call this art eclectic, commercial and the like. Examples of Serbian music get into such style directives. The New Ideas Symphony by film score composer Zoran Simjanović, was performed in the open air at Kalemegdan fortress in 2006, before an audience of about one thousand people. Since then the recording has often been broadcast on television and radio channels. In its combination of folklore and film models, traces of rock, pop, and jazz can also be found, in a score with all symphonic characteristics. This attempt is a fascinating item for research as well as a pleasure to be listened to.

  7. Is the Unspeakable Singable? The Ethics of Holocaust Representation and the Reception of Górecki's Symphony no.3

    Directory of Open Access Journals (Sweden)

    Alison Moore

    2011-08-01

    Full Text Available Debates about Holocaust representation have long been haunted by the idea that the enormity and intensity of human suffering in the events of World War Two are ‘unspeakable’. In many such statements the capacity for cognition and the ethical dimension of aestheticisation are blurred – the Holocaust is ‘unspeakable’ both in the sense of being impossible to imagine in its full horror, but also morally inappropriate as the subject of artistic production. But do all forms of cultural representation of the Holocaust fail in the same way as words or to the same degree, in the eyes of those who would judge their merits according the tenet of unspeakability? This paper considers one particularly renowned work Henryk Górecki’s symphony no. 3 (Symfonia pieśni żałosnych of 1976, discussing how it mediated both the global politics of Holocaust representation and the recuperation of victimhood in postcommunist Poland. Górecki claimed a subjectivity of failure in response to the challenge of representing the events of World War Two and has insisted that the symphony is not about war but about sorrow. The vocal lyrics are nonetheless profoundly thematised around war suffering, and the Second World War in particular - events he approached with a musical language of epic, pathos and redemption. In framing the subject of his work, he emphasised a Polish national suffering that both eschewed mention of specifically targeted groups of victims, and beckoned to Polish folk and catholic traditions. This article presents a new hypothesis about the success of Górecki’s work by considering it in relation to the ethical debates about Holocaust empathic response that have occurred in relation to historiographic, literary and filmic representation.

  8. IDM-PhyChm-Ens: intelligent decision-making ensemble methodology for classification of human breast cancer using physicochemical properties of amino acids.

    Development of an accurate and reliable intelligent decision-making method for the construction of cancer diagnosis system is one of the fast growing research areas of health sciences. Such decision-making system can provide adequate information for cancer diagnosis and drug discovery. Descriptors derived from physicochemical properties of protein sequences are very useful for classifying cancerous proteins. Recently, several interesting research studies have been reported on breast cancer classification. To this end, we propose the exploitation of the physicochemical properties of amino acids in protein primary sequences such as hydrophobicity (Hd) and hydrophilicity (Hb) for breast cancer classification. Hd and Hb properties of amino acids, in recent literature, are reported to be quite effective in characterizing the constituent amino acids and are used to study protein foldings, interactions, structures, and sequence-order effects. Especially, using these physicochemical properties, we observed that proline, serine, tyrosine, cysteine, arginine, and asparagine amino acids offer high discrimination between cancerous and healthy proteins. In addition, unlike traditional ensemble classification approaches, the proposed 'IDM-PhyChm-Ens' method was developed by combining the decision spaces of a specific classifier trained on different feature spaces. The different feature spaces used were amino acid composition, split amino acid composition, and pseudo amino acid composition. Consequently, we have exploited different feature spaces using Hd and Hb properties of amino acids to develop an accurate method for classification of cancerous protein sequences. We developed ensemble classifiers using diverse learning algorithms such as random forest (RF), support vector machines (SVM), and K-nearest neighbor (KNN) trained on different feature spaces. We observed that ensemble-RF, in case of cancer classification, performed better than ensemble-SVM and ensemble-KNN. Our

  9. Influences de la symphonie concertante sur la musique de la Cour parisienne sous l'Empire et la Restauration (1800-1830

    Directory of Open Access Journals (Sweden)

    Dratwicki, Alexandre

    2003-12-01

    Full Text Available The origins of the very much appreciated "symphonie concertante" can be found in the importance of public concerts given in Paris at the end of the 18th century. The specific repertoire played at the French Court during the years 1800-1830 distinctly shows this vogue for the "symphonie concertante", for it reveals the still unknown importance of virtuosity. Considered as an musical entertainment for the pompous parties at the French Court or as an musical accompaniment for the masses given at the Imperial and Royal Chapel, this "decorative concertant syle" became an essential part of the Regime etiquette during the Napoleonic empire as well as the Restoration period. This music, perfectly incorporated into the official guidelines, will disappear as a consequence of the political events of 1830 and the arrival of a new aesthetic movement, the Romanticism.

    [fr] La vogue du concert public à Paris, à la fin du XVIIIe siècle, fut à l'origine de l'essor phénoménal que connut la symphonie concertante. Le répertoire de la musique de la Cour - entre 1800 et 1830 - est particulièrement représentatif de cette mode : il révèle une place encore insoupçonnée laissée à la virtuosité. Agrémentant les messes de la Chapelle ou les bals donnés lors de fastueuses soirées, ce « style concertant décoratif » devint un élément constitutif de l'apparat gouvernemental sous l'Empire et la Restauration. Une sorte d'académisme officiel que les événements politiques de 1830 et l'essor du romantisme musical feront définitivement disparaître.

  13. Symphony no. Alcuin's Riddle.

    Science.gov (United States)

    Veeneman, Curt H.

    Alcuin, an eighth century poet, mathematician, educator and cleric, was the foremost scholar of the Carolingian Renaissance. Indeed, he was Charlemagne's antidote to illiteracy in the middle ages. He also loved riddles. One of his riddles, a, favorite of mine, presents a ferrying problem: A man has a wolf, a goat, and a bundle of cabbages. He must cross a river, but his boat is so small that he can take only one of them at a time. For obvious reasons, he cannot leave the goat with the cabbages, nor the wolf with the goat. The question is how many crossings must he make. The solution to this riddle suggested an intriguing form to me: one that is not only rounded, but has palindromic characteristics. The concept of a time-space relationship informs the large-scale design of this work. I have made the audience the "river," allowing them to hear the solution to the riddle unfold--in the midst of the action. (And once an audience member solves the riddle he will have a sense of when the music will end!) The work is scored for an orchestra on stage and 15 soloists in the audience, who span the auditorium from the stage to the rear, and function as a medium by which the music crosses the audience-river.

    2016-01-01

    Traditional approaches to interpret poetry have been poet-oriented, appearing alien to reader’s understanding and ap-preciation, which are generally insensitive to the aesthetic and emotional reflection during the process of analyzing poetry. This essay aims to combine cognitive poetics with multimodal discourse analysis (MDA) to analyze concrete poems from readers’ angle. In this research, figure and ground, conceptual metaphor, and image schema of cognitive poetics are adopted to interpret A War Symphony and l(a from the perspective of visual modality and auditory modality. Meanwhile, the differences between Chi-nese and English concrete poetry in modality choosing and meaning conveying as well as the reasons are explored. This research reveals that readers are able to comprehend poetic meaning according to their life experiences. The multi-dimensional perspec-tive of visual and auditory modalities is conductive to exploring how readers challenge traditional reading mode to interpret poet-ic ideas. Meanwhile, three theories of cognitive poetics facilitate readers to perceive poetics effect with a cognitive mechanism. Therefore, all of these efforts are bound to arouse readers’interest in such a kind of anti-traditional poetry and broaden its popu-larity.

    Twenty four hour ambulatory ST segment monitoring was performed on 48 members (43 players and five members of the management/technical team) of the British Broadcasting Corporation (BBC) symphony orchestra without a history of cardiac disease. This period included final rehearsals and live performances (for audience and radio) of music by Richard Strauss and Mozart at the Royal Festival Hall (n = 36) and Rachmaninov and Tchaikovsky at the Barbican Arts Centre (n = 21). During the period of monitoring one person (2%) had transient ST segment changes. Mean heart rates were significantly higher during the live performances than during the rehearsals. Mean heart rates during the live performance of Rachmaninov and Tchaikovsky were significantly higher than during Strauss and Mozart in those (n = 6) who were monitored on both occasions. Mean heart rates in the management and technical team were higher than those of the players. The recognised circadian pattern of heart rate, with a peak in the morning waking hours, was altered similarly during both concert days, with a primary peak occurring in the evening hours and a lesser peak in the morning for both musicians and management/technical staff. This study showed that environmental factors are of primary importance in defining the circadian pattern of heart rate. This has important implications when identifying peak periods of cardiovascular stress and tailoring drug treatment for patients with angina pectoris.

    Full Text Available Despite a high level of sound exposure and a fairly large selection of earplugs available, musicians have often been reported to use personal hearing protectors only seldom. For better hearing conservation, it is important to identify and eliminate the causes for the low motivation to use hearing protection. We explored the usage rate of custom-molded musician′s earplugs (ER-15 among 15 symphony orchestra musicians with a questionnaire, and measured the attenuation properties of their earplugs with a Real-Ear Attenuation at Threshold (REAT procedure in a sound field. Earplug use was found to be low, and the musicians reported that earplugs hampered listening to their own and their colleagues′ playing; earplugs affected either timbre or dynamics, or both. Additionally, several reasons related to discomfort of use were itemized, but the musicians who consistently used their earplugs did so in spite of problems with use. The REAT values obtained in sound field were relatively close to the manufacturer′s nominal specifications, being 13.7 dB, on average. In the frequency range studied (0.125-8 kHz, individual variation in REAT was, however, up to 15 dB across the measured frequencies. Fluctuation in attenuation might be related to low use of hearing protectors, and REAT measured at fixed center frequencies may be too robust a method to uncover it. We therefore tested 10 additional subjects to find out whether a sweeping signal used in Bιkιsy audiometry would bring more detailed information on earplug attenuation. Mean attenuation was found to be somewhat closer to the nominal attenuation of the ER-9 and ER-15 earplugs up to about 1 kHz, whereas REAT measurements in sound field revealed more even attenuation at frequencies between 1 and 6 kHz. No significant association was found between earplug attenuation properties and earplug use. It was concluded that support and determination to get accustomed to hearing protector use are important

    Peter llyich Tchaikovsky is the most representative and the most poplar composer in Russia. As a master of Russian folk music and European classic music, he is extolled as the“Bright Lamp of Russian Music”by Russians. Of his countless music works, The Sixth Symphony (also named The Compassionate Symphony) is his last work. As his master piece, this work is a refection of his fright, despair and failure in life and also is an embodiment of his world outlook, views on life and views on love, etc. All his works can amount to the theme“compassionate” and The Sixth Symphony centrally reflects this theme. This paper interprets the theme of the“compassionate”in this work.%彼得·伊里奇·柴科夫斯基是俄罗斯作曲家中最为杰出的一位代表,也是最受欢迎的作曲家,同时也是俄罗斯民族音乐与西欧古典音乐的集大成者,他被俄罗斯人民骄傲地称为“俄罗斯音乐的明灯”。他的作品不计其数,《第六交响曲》(也被称为《悲怆交响曲》)是他最后一部作品,同时也是他的巅峰之作,这首交响曲包含了他对人生的恐怖、绝望与失败等情绪,也可以说是世界观、人生观和爱情观的具体体现。柴科夫斯基一生所创作的作品都可以用一个“悲”字来形容,而《第六交响曲》则是其最高境界,文章具体阐释了该曲中“悲”的寓意。

  20. Gravitational Lensing: Einstein's unfinished symphony

    Treu, Tommaso; Ellis, Richard S.

    2015-01-01

    Gravitational lensing - the deflection of light rays by gravitating matter - has become a major tool in the armoury of the modern cosmologist. Proposed nearly a hundred years ago as a key feature of Einstein's theory of general relativity, we trace the historical development since its verification at a solar eclipse in 1919. Einstein was apparently cautious about its practical utility and the subject lay dormant observationally for nearly 60 years. Nonetheless there has been rapid progress over the past twenty years. The technique allows astronomers to chart the distribution of dark matter on large and small scales thereby testing predictions of the standard cosmological model which assumes dark matter comprises a massive weakly-interacting particle. By measuring the distances and tracing the growth of dark matter structure over cosmic time, gravitational lensing also holds great promise in determining whether the dark energy, postulated to explain the accelerated cosmic expansion, is a vacuum energy density or a failure of general relativity on large scales. We illustrate the wide range of applications which harness the power of gravitational lensing, from searches for the earliest galaxies magnified by massive clusters to those for extrasolar planets which temporarily brighten a background star. We summarise the future prospects with dedicated ground and space-based facilities designed to exploit this remarkable physical phenomenon.

    Gravitational lensing - the deflection of light rays by gravitating matter - has become a major tool in the armoury of the modern cosmologist. Proposed nearly a hundred years ago as a key feature of Einstein's theory of General Relativity, we trace the historical development since its verification at a solar eclipse in 1919. Einstein was apparently cautious about its practical utility and the subject lay dormant observationally for nearly 60 years. Nonetheless there has been rapid progress over the past twenty years. The technique allows astronomers to chart the distribution of dark matter on large and small scales thereby testing predictions of the standard cosmological model which assumes dark matter comprises a massive weakly-interacting particle. By measuring distances and tracing the growth of dark matter structure over cosmic time, gravitational lensing also holds great promise in determining whether the dark energy, postulated to explain the accelerated cosmic expansion, is a vacuum energy density or a...

    The new millennium will see the upcoming of several ground-based interferometric gravitational wave antennas. Within the next decade a space-based antenna may also begin to observe the distant Universe. These gravitational wave detectors will together operate as a network taking data continuously for several years, watching the transient and continuous phenomena occurring in the deep cores of astronomical objects and dense environs of the early Universe where gravity was extremely strong and highly nonlinear. The network will listen to the waves from rapidly spinning non-axisymmetric neutron stars, normal modes of black holes, binary black hole inspiral and merger, phase transitions in the early Universe, quantum fluctuations resulting in a characteristic background in the early Universe. The gravitational wave antennas will open a new window to observe the dark Universe unreachable via other channels of astronomical observations.

    Posttranslational regulation of macroautophagy (hereafter autophagy), including phosphorylating and dephosphorylating components of the autophagy-related (Atg) core machinery and the corresponding upstream transcriptional factors, is important for the precise modulation of autophagy levels. Several kinases that are involved in phosphorylating autophagy-related proteins have been identified in both yeast and mammalian cells. However, there has been much less research published with regard to the identification of the complementary phosphatases that function in autophagy. A recent study identified PPP3/calcineurin, a calcium-dependent phosphatase, as a regulator of autophagy, and demonstrated that one of the key targets of PPP3/calcineurin is TFEB, a master transcriptional factor that controls autophagy and lysosomal function in mammalian cells.

  4. Hadronic octaves: Symphony in treble clef

    International Nuclear Information System (INIS)

    Pythagoreanism, as derived from the physics of music, an artificial quantized system, involved simple ratios between integers and was conjectured by the Pythagoreans to extend to the whole of physics (the Music of the Spheres). It hit the jackpot in 1895 with Balmer's formula and has dominated XXth Century physics, with its Quantum Foundations. I review the history of Hadron Spectroscopy and my personal role in 1958-1964, i.e. (1) my 1960 discovery of SU(3) symmetry with an octet assignment for the j = (1/2) baryons (independently reached somewhat later by M. Gell-Mann), and (2) in 1961 (with H. Goldberg) my mathematical construction of a structural model which was then developed into the physical quark model by Gell-Mann and Zweig

The sample in the research, which was carried out by survey method, is consist of the concert programs of ten symphony orchestras between the period of foundation dates and the 2013-14 concert season. In data collection process the archives of the related orchestras was searched and analysed. The gathered data analysed by frequency and percentage method. The result shows that classical guitar pieces were appeared to some extent in concert programs of the symphony orchestras in Turkey. The frequencies of the appearence of the clasical guitar pieces in the concert programs had increased through the years. This increment has gained an acceleration since 1990. The large majority of the classical guitar pieces were belonged to the 20.th century composers and the most played classical guitar piece was Concierto de Aranjuez by Rodrigo. Appearance of the Turkish pieces in the programs were very low. Until the year 2000 the great majority of the guitarists that played with the orchestras were foreigner but since 2000 Turkish guitarist were appeared mostly on stages. ÖzetBu araştırma Türkiye’de faaliyet göstermekte olan senfoni orkestralarının konser programlarında klasik gitarın yer alma durumunun çeşitli değişkenler açısından incelenmesi amacıyla yapılmıştır.

  16. The black hole symphony: probing new physics using gravitational waves.

    Science.gov (United States)

    Gair, Jonathan R

    2008-12-13

    The next decade will very likely see the birth of a new field of astronomy as we become able to directly detect gravitational waves (GWs) for the first time. The existence of GWs is one of the key predictions of Einstein's theory of general relativity, but they have eluded direct detection for the last century. This will change thanks to a new generation of laser interferometers that are already in operation or which are planned for the near future. GW observations will allow us to probe some of the most exotic and energetic events in the Universe, the mergers of black holes. We will obtain information about the systems to a precision unprecedented in astronomy, and this will revolutionize our understanding of compact astrophysical systems. Moreover, if any of the assumptions of relativity theory are incorrect, this will lead to subtle, but potentially detectable, differences in the emitted GWs. Our observations will thus provide very precise verifications of the theory in an as yet untested regime. In this paper, I will discuss what GW observations could tell us about known and (potentially) unknown physics. PMID:18812300

The research area for this investigation was purposively selected as the Vietnam National Academy of Music in Hanoi. The investigation began in October 2012 and was concluded in January 2014. The two key informants for this investigation were expert conductors and teachers at the academy, Dr. Nguyễn Phúc Linh and Dr. Nguyễn Thiếu Hoa. Data was collected from a combination of document analysis and field research. Tools used for data collection included interviews, participant and non-participant observation and focus group discussions. Results show that both of the key informants for this investigation were born into families of artists and had a particularly close relationship with traditional folk art. Scholarships to study abroad at the Tchaikovsky University, Russia enabled them to learn from Russian conductors and they developed the skills that have now led them to be recognized as being among the most accomplished conductors in Vietnam. The process of instruction preferred by these two academics is taught in three steps: the preparation stage, the teaching stage and the assessment and evaluation stage. The benefits of studying with Dr. Nguyễn Phúc Linh and Dr. Nguyễn Thiếu Hoa are the cumulative experiences of international conducting practices and the high standards that the two academics possess and demand.

  15. It's a bittersweet symphony: simultaneously mixed emotional responses to music with conflicting cues.

    Science.gov (United States)

    Larsen, Jeff T; Stastny, Bradley J

    2011-12-01

    Some evidence indicates that emotional reactions to music can be organized along a bipolar valence dimension ranging from pleasant states (e.g., happiness) to unpleasant states (e.g., sadness), but songs can contain some cues that elicit happiness (e.g., fast tempos) and others that elicit sadness (e.g., minor modes). Some models of emotion contend that valence is a basic building block of emotional experience, which implies that songs with conflicting cues cannot make people feel happy and sad at the same time. Other models contend that positivity and negativity are separable in experience, which implies that music with conflicting cues might elicit simultaneously mixed emotions of happiness and sadness. Hunter, Schellenberg, and Schimmack (2008) tested these possibilities by having subjects report their happiness and sadness after listening to music with conflicting cues (e.g., fast songs in minor modes) and consistent cues (e.g., fast songs in major modes). Results indicated that music with conflicting cues elicited mixed emotions, but it remains unclear whether subjects simultaneously felt happy and sad or merely vacillated between happiness and sadness. To examine these possibilities, we had subjects press one button whenever they felt happy and another button whenever they felt sad as they listened to songs with conflicting and consistent cues. Results revealed that subjects spent more time simultaneously pressing both buttons during songs with conflicting, as opposed to consistent, cues. These findings indicate that songs with conflicting cues can simultaneously elicit happiness and sadness and that positivity and negativity are separable in experience.

  17. Chronic obstructive pulmonary disease and glucose metabolism: a bitter sweet symphony

    Directory of Open Access Journals (Sweden)

    Mirrakhimov Aibek E

    2012-10-01

    Full Text Available Abstract Chronic obstructive pulmonary disease, metabolic syndrome and diabetes mellitus are common and underdiagnosed medical conditions. It was predicted that chronic obstructive pulmonary disease will be the third leading cause of death worldwide by 2020. The healthcare burden of this disease is even greater if we consider the significant impact of chronic obstructive pulmonary disease on the cardiovascular morbidity and mortality. Chronic obstructive pulmonary disease may be considered as a novel risk factor for new onset type 2 diabetes mellitus via multiple pathophysiological alterations such as: inflammation and oxidative stress, insulin resistance, weight gain and alterations in metabolism of adipokines. On the other hand, diabetes may act as an independent factor, negatively affecting pulmonary structure and function. Diabetes is associated with an increased risk of pulmonary infections, disease exacerbations and worsened COPD outcomes. On the top of that, coexistent OSA may increase the risk for type 2 DM in some individuals. The current scientific data necessitate a greater outlook on chronic obstructive pulmonary disease and chronic obstructive pulmonary disease may be viewed as a risk factor for the new onset type 2 diabetes mellitus. Conversely, both types of diabetes mellitus should be viewed as strong contributing factors for the development of obstructive lung disease. Such approach can potentially improve the outcomes and medical control for both conditions, and, thus, decrease the healthcare burden of these major medical problems.

These interacting proteins decide the subcellular localization of Rap, the interaction modes with downstream Rap effectors and tune Rap as an atypical molecular conductor, coupling extra- and intracellular signals to various pathways. In this review, we summarize four groups of Rap-interacting proteins, highlight their distinctions in Rap-binding properties and interactive modes and discuss their contribution to the spatiotemporal regulation of Rap as well as the implications of targeting Rap-interacting proteins in human cancer therapy.

  19. It's a bittersweet symphony: simultaneously mixed emotional responses to music with conflicting cues.

    Larsen, Jeff T; Stastny, Bradley J

    Some evidence indicates that emotional reactions to music can be organized along a bipolar valence dimension ranging from pleasant states (e.g., happiness) to unpleasant states (e.g., sadness), but songs can contain some cues that elicit happiness (e.g., fast tempos) and others that elicit sadness (e.g., minor modes). Some models of emotion contend that valence is a basic building block of emotional experience, which implies that songs with conflicting cues cannot make people feel happy and sad at the same time. Other models contend that positivity and negativity are separable in experience, which implies that music with conflicting cues might elicit simultaneously mixed emotions of happiness and sadness. Hunter, Schellenberg, and Schimmack (2008) tested these possibilities by having subjects report their happiness and sadness after listening to music with conflicting cues (e.g., fast songs in minor modes) and consistent cues (e.g., fast songs in major modes). Results indicated that music with conflicting cues elicited mixed emotions, but it remains unclear whether subjects simultaneously felt happy and sad or merely vacillated between happiness and sadness. To examine these possibilities, we had subjects press one button whenever they felt happy and another button whenever they felt sad as they listened to songs with conflicting and consistent cues. Results revealed that subjects spent more time simultaneously pressing both buttons during songs with conflicting, as opposed to consistent, cues. These findings indicate that songs with conflicting cues can simultaneously elicit happiness and sadness and that positivity and negativity are separable in experience. PMID:21707144

    Full Text Available The empirical foundation of executive control function (ECF remains controversial. We have employed structural equation models (SEM to explicitly distinguish domain-specific variance in ECF performance from memory (MEM and shared cognitive performance variance, i.e., Spearman’s g. ECF does not survive adjustment for both MEM and g in a well fitting model of data obtained from non-demented older persons (N = 193. Instead, the variance in putative ECF measures is attributable only to g, and related to functional status only through a fraction of that construct (i.e., dECF. dECF is a homolog of the latent variable δ, which we have previously associated specifically with the Default Mode Network (DMN. These findings undermine the validity of ECF and its putative association with the frontal lobe. ECF may have no existence independent of general intelligence, and no functionally salient association with the frontal lobe outside of that structure’s contribution to the DMN.

    Biological motion observation has been recognized to produce dynamic change in sensorimotor activation according to the observed kinematics. Physical plausibility of the spatial-kinematic relationship of human movement may play a major role in the top-down processing of human motion recognition. Here, we investigated the time course of scalp activation during observation of human gait in order to extract and use it on future integrated brain-computer interface using virtual reality (VR). We analyzed event related potentials (ERP), the event related spectral perturbation (ERSP) and the inter-trial coherence (ITC) from high-density EEG recording during video display onset (-200-600 ms) and the steady state visual evoked potentials (SSVEP) inside the video of human walking 3D-animation in three conditions: Normal; Upside-down (inverted images); and Uncoordinated (pseudo-randomly mixed images). We found that early visual evoked response P120 was decreased in Upside-down condition. The N170 and P300b amplitudes were decreased in Uncoordinated condition. In Upside-down and Uncoordinated conditions, we found decreased alpha power and theta phase-locking. As regards gamma oscillation, power was increased during the Upside-down animation and decreased during the Uncoordinated animation. An SSVEP-like response oscillating at about 10 Hz was also described showing that the oscillating pattern is enhanced 300 ms after the heel strike event only in the Normal but not in the Upside-down condition. Our results are consistent with most of previous point-light display studies, further supporting possible use of virtual reality for neurofeedback applications. PMID:25278847

In the early 19th century, a hard time in which the ordinary people were making their living hopelessly, it was Beethoven's Fifth Symthony that brought about hope and courage to their spiritual world. Though more 200 years have passed away, its exciting and encouraging music still resound to the sky, which stimulates people to make a review into its musical charm. This paper makes a thorough analysis of the ratistic value and charm of Beethoven's Fifth Symthony from multipl perspectives, attempting to probe into its inner meaning in more diversified as-pects.

    Information flow management plays a significant role in ensuring the reliable exchange of Building Information Modeling (BIM) information between project participants in the Architecture, Engineer-ing, Construction, and Facility Management (AEC/FM) industry. The buildingSMART standard approach...... to resolve this issue is based on the Information Delivery Manual (IDM). The IDMs in current use indicate that focus has mainly been on formalizing multifaceted and wide-ranging AEC/FM processes, and therefore often involve multiple use cases. Because IDMs typically describe such complex processes...... generic IDM Packages for all main use cases of the AEC/FM project life cycle. In this methodology, an IDM Project Plan can be created by selecting the specific IDM Packages required for the specific AEC/FM project. Ultimately, we believe that the IDM Framework will help improve information flow management...

    Full Text Available The First Symfoni No 40 Wolfgang Amadeus Mozart. Symphony is a great composition, whichconventionally consists of four parts. At the end of the eighteenth century it became the main format of orchestralmusic. However, it became prominent at the time of Beethoven. Symphony is a great and ambitious piece of musicsince it is played for 20-45 minutes in length, containing an expansion of tone colors and dynamics of classicalorchestra. It has been known that classical symphony usually consists of four parts inciting broader emotion bythe created tempo and nuance. Mozart’s three last symphonies are Mozart’s masterpieces and Symphony No. 40,for example, contains connotations of romantic signs ignored by his predecessors. Although Symphony No. 40employs minor tones, it is not sad but cheerful, playful, passionful, and dramatic. The fi rst part of the Symphonyuses Allegro Sonata format which consists of three parts, namely exposition, development and recapitulation.

  16. A Human-Centred Approach to National Identity Management Systems

    This thesis explores the concept of a human-centred Identity Management System (IDMS), and how it can be implemented by organisations. The review of the literature on previous approaches to identity (i.e. privacy, trust, and usability) reveals that claims of IDMS being ‘human-centred’ are rhetorical; in reality, organisations’ administrative convenience is prioritised over the needs of individuals who are treated as purely functional components within the IDMS ecosystem.

  6. 试论韩国《春香传》故事中青春与爱情的交响%A Preliminary Study into the Symphony of Youth and Love in the Korean Story Empress Chung

    Institute of Scientific and Technical Information of China (English)

    许建昆; 崔圭万

    2015-01-01

    Three versions of the Korean romance Empress Chung exist in Taiwan, namely Empress Chung in Chinese, the Shuishan edition of Guang Han Lou Ji, and a translation from the Chonju version of A Spring Festival Song by Liu Yingjiu. Considering the maturity of the story-line, Empress Chung in Chinese is the earliest version. All these versions were adapted from operas of different historical periods. However, the operas from various times evolved respectively from the performing art of Pansori. Therefore, Pansori is the true source of the opera and novel versions of Empress Chung. In stories emerged during the later periods, the academic circle focused more on the revolt against authority, the identity of the protagonist, the form of marriage and the chastity of women, while ignored the motif of dominant role of love. The paper discusses the literary genres and motif representations of various versions, and demonstrates that the core motif of Empress Chung should be an ode to youth and love.%就台湾所见韩国传奇小说《春香传》,有《汉文春香传》、水山《广寒楼记》本,以及柳应九依据全州完版本《烈女春香守节歌》的译本三种。从故事情节的成熟度而言,应以《汉文春香传》为最早。它们都是根据不同时代的戏剧形式而改编。然而,这些不同时代的戏剧,各自从盘骚里的表演艺术演化而成。所以说,盘骚里才是《春香传》戏曲与小说类型真正的源头。在越晚期发展的故事里,学界似乎强调反抗威权、主角身份、婚姻形式与女性贞节,反而忽略了爱情至上的母题。文章论述各种版本的文体类型与主题表现,证明歌咏青春与爱情才是《春香传》的核心母题。

    2016-06-01

    As a perspective on Mammen and Miroenkos the article is reflecting on the possibility of Activity Theory being a foundation on which Psychology could be integrated. Mammen and Miroenkos point that directed activity not only is towards objects "defined as a sum of qualities, but by individual reference" is a starting point. As a specific example the phenomenon Love, as "significant object relations", is related to the concept "choice categories". It is stated that relations of affection and love can't be understood independent of history of common activity, and that this makes the concept "choice categories" central in a psychological understanding of what love is.

    2013-10-01

    Full Text Available This article sets out to increase awareness regarding the wide and universal significance of disability, as well as the important benefits of an Integrated Disability Management (IDM approach. The scientific basis for IDM is explored in the first place through an analysis of its relationship to the International Classification of Functioning, Disability and Health (ICF. The conceptual paradigm of the ICF shares an ideological position with the IDM approach in that they are both underpinned by dynamic and multidimensional constructions of disability, which imply equally holistic and interdisciplinary responses. The IDM approach can be applied across a diversity of human situations to provide solutions that reflect the multifaceted and widespread nature of disability. The IDM approach is intended as a strategy capable of handling: inclusion of people with disabilities, active aging of human resources, health and safety in the workplace, prevention of disabilities and various diseases, return-to-work, absenteeism, and presenteeism.

    2011-01-01

    Objective To explore older adults’ views of existing Informed Decision Making (IDM) elements and investigate the need for additional elements. Methods We recruited persons 65 and older to participate in six focus groups. Participants completed questionnaires about IDM preferences, and discussed videotapes of idealized patient-physician interactions in light of seven IDM elements: 1) discussion of the patient's role in decision-making; 2) discussion of the clinical issue; 3) discussion of alternatives; 4) discussion of benefits/risks; 5) discussion of uncertainties; 6) assessment of patient understanding; and 7) exploration of patient preference. We used a modified grounded theory approach to assess agreement with existing IDM elements and identify new elements. Results In questionnaires, 97–100% of 59 participants rated each IDM element as “somewhat” or “very” important. Qualitative analysis supported existing elements and suggested two more: opportunity for input from trusted others, and discussion of decisions’ impacts on patients’ daily lives. Elements overlapped with global communication themes. Conclusion Focus groups affirmed existing IDM elements and suggested two more with particular relevance for older patients. Practice implications Incorporation of additional IDM elements into clinical practice can enhance informed participation of older adults in decision-making. PMID:21757315

    2014-11-01

    Inulin, a naturally occurring polysaccharide, was acetylated to make it processable by electrospraying, a facile and single step method for microparticle fabrication. Electrospraying process parameters were optimized for fabrication of spherical and monodisperse indomethacin (IDM) loaded inulin acetate (INA) microparticles. The apparent entrapment efficiency of IDM was determined to be 100%, whereas working encapsulation efficiency was estimated to be 35.39 ± 1.63%. Differential scanning calorimetry and X-ray diffraction analysis confirmed molecular dispersion of IDM in an amorphous state within the INA matrix. Finally, the results from in vitro release study performed in simulated gastro-intestinal fluids demonstrated that IDM was released only in simulated colonic fluid that contained inulinase. Therefore, this study demonstrates that acetylation of inulin does not alter its susceptibility to inulinase and that microparticles fabricated from INA can be developed as a colon targeting drug delivery system.

  11. Influence of pH and method of crystallization on the solid physical form of indomethacin.

    The purpose of this study was to investigate the effect of pH and method of crystallization on the solid physical form of indomethacin (IDM). IDM, a non steroidal anti-inflammatory drug poorly soluble in water, underwent two different crystallization methods: crystallization by solvent evaporation under reduced pressure at 50.0°C (method A), and crystallization by cooling of solution from 50.0 to 5.0°C (method B). In both cases, several aqueous ethanolic solutions of IDM of different pHs were prepared. pHs were adjusted by adding acidic solutions (HCl 2M) or alkali (NaOH or NH4OH 2M) to an aqueous ethanolic solution of IDM. Thus, several batches were recovered after crystallization. The chemical stability of IDM was verified through (1)H NMR and mass spectroscopy (FIA-ESI-MS), that revealed that IDM degraded in strong alkali media (pH ≥ 12). Crystals obtained under different crystallization conditions at pHs of 1.0, 4.5, 7.0, 8.0, 10.0 and chemically stable were thus characterized for crystal habit by scanning electron microscopy, for thermal behaviour by differential scanning calorimetry, and thermogravimetry, and for solid state by X-ray powder diffractometry. Under the Method A, IDM always crystallized into pure metastable alpha form when solutions were acidified or alkalized respectively with HCl and NH4OH. On the contrary, in presence of NaOH, IDM crystallized under a mixture of alpha and sodium trihydrate form, because the presence of the sodium counter ion orientates the crystallization towards the formation of the trihydrate salt. Under the method B, at pH of 1.0, IDM crystallized under the alpha form; at pH 4.5, IDM crystallized under the form alpha in presence of some nuclei of gamma form; at pH 7.0, 8.0, and 10.0 for NH4OH, IDM crystallized under the most stable polymorph gamma form, whereas in presence of NaOH, a mix of alpha, and salt forms was formed whatever the pH of the solution.

IDM, a non steroidal anti-inflammatory drug poorly soluble in water, underwent two different crystallization methods: crystallization by solvent evaporation under reduced pressure at 50.0°C (method A), and crystallization by cooling of solution from 50.0 to 5.0°C (method B). In both cases, several aqueous ethanolic solutions of IDM of different pHs were prepared. pHs were adjusted by adding acidic solutions (HCl 2M) or alkali (NaOH or NH4OH 2M) to an aqueous ethanolic solution of IDM. Thus, several batches were recovered after crystallization. The chemical stability of IDM was verified through (1)H NMR and mass spectroscopy (FIA-ESI-MS), that revealed that IDM degraded in strong alkali media (pH ≥ 12). Crystals obtained under different crystallization conditions at pHs of 1.0, 4.5, 7.0, 8.0, 10.0 and chemically stable were thus characterized for crystal habit by scanning electron microscopy, for thermal behaviour by differential scanning calorimetry, and thermogravimetry, and for solid state by X-ray powder diffractometry. Under the Method A, IDM always crystallized into pure metastable alpha form when solutions were acidified or alkalized respectively with HCl and NH4OH. On the contrary, in presence of NaOH, IDM crystallized under a mixture of alpha and sodium trihydrate form, because the presence of the sodium counter ion orientates the crystallization towards the formation of the trihydrate salt. Under the method B, at pH of 1.0, IDM crystallized under the alpha form; at pH 4.5, IDM crystallized under the form alpha in presence of some nuclei of gamma form; at pH 7.0, 8.0, and 10.0 for NH4OH, IDM crystallized under the most stable polymorph gamma form, whereas in presence of NaOH, a mix of alpha, and salt forms was formed whatever the pH of the solution.

  17. Centaure: an heterogeneous parallel architecture for computer vision

    International Nuclear Information System (INIS)

    This dissertation deals with the architecture of parallel computers dedicated to computer vision. In the first chapter, the problem to be solved is presented, as well as the architecture of the Sympati and Symphonie computers, on which this work is based. The second chapter is about the state of the art of computers and integrated processors that can execute computer vision and image processing codes. The third chapter contains a description of the architecture of Centaure. It has an heterogeneous structure: it is composed of a multiprocessor system based on Analog Devices ADSP21060 Sharc digital signal processor, and of a set of Symphonie computers working in a multi-SIMD fashion. Centaure also has a modular structure. Its basic node is composed of one Symphonie computer, tightly coupled to a Sharc thanks to a dual ported memory. The nodes of Centaure are linked together by the Sharc communication links. The last chapter deals with a performance validation of Centaure. The execution times on Symphonie and on Centaure of a benchmark which is typical of industrial vision, are presented and compared. In the first place, these results show that the basic node of Centaure allows a faster execution than Symphonie, and that increasing the size of the tested computer leads to a better speed-up with Centaure than with Symphonie. In the second place, these results validate the choice of running the low level structure of Centaure in a multi- SIMD fashion. (author)

    We investigated the effects of the particle size of indomethacin-loaded poly-L-lactic acid microspheres (IDM-loaded PLA MS), the helium pressure used to accelerate the particles, and the bombardment dose of PLA MS on the plasma concentration of IDM after bombarding with IDM-loaded PLA MS of different particle size ranges, 20-38, 44-53 and 75-100 microm, the abdomen of hairless rats using the Helios gene gun system (Helios gun system). Using larger particles and a higher helium pressure, produced an increase in the plasma IDM concentration and the area under the plasma concentration-time curve (AUC) and resultant F (relative bioavailability with respect to intracutaneous injection) of IDM increased by an amount depending on the particle size and helium pressure. Although a reduction in the bombardment dose led to a decrease in C(max) and AUC, F increased on decreasing the bombardment dose. In addition, a more efficient F was obtained after bombarding with IDM-loaded PLA MS of 75-100 microm in diameter at each low dose in different sites of the abdomen compared with that after bolus bombardment with a high dose (dose equivalent). These results suggest that the bombardment injection of drug-loaded microspheres by the Helios gun system is a very useful tool for delivering a variety of drugs in powder form into the skin and systemic circulation.

    A possible feature of the Inert Doublet Model (IDM) is to provide a dark matter candidate together with an alteration of both direct and indirect collider constraints that allow for a heavy Higgs boson. We study the IDM in light of recent results from Higgs searches at the Large Hadron Collider (LHC) in combination with dark matter direct-detection limits from the XENON experiment. We ask under what conditions the IDM can still accommodate a heavy Higgs boson. We find that IDM scenarios with a Higgs boson in the mass range 160 to 600 GeV are ruled out only when all experimental constraints are combined. For models explaining only a fraction of the DM the limits are weakened, and IDMs with a heavy Higgs are allowed. We discuss the prospects for future detection of such IDM scenarios in the four-lepton plus missing energy channel at the LHC. This signal can show up in the first year of running at {radical}(s)=14 TeV, and we present detector-level studies for a few benchmark models. (orig.)

    Graphical abstract: -- Highlights: •We develop a strategy to evaluate matrix effect and its impact on the IDMS results. •Matrix effect and IDMS correction factor from different conditions are evaluated. •Ion suppression effect is observed in LLE and HLB pre-treated sample solutions. •Ion enhancement effect is found in MCX pre-treated sample solution. •IDMS correction factor in HLB and MCX solutions in three instruments is close to 1 -- Abstract: In the present study, we developed a comprehensive strategy to evaluate matrix effect (ME) and its impact on the results of isotope dilution mass spectrometry (IDMS) in analysis of chloramphenicol (CAP) residues in milk powder. Stable isotope-labeled internal standards do not always compensate ME, which brings the variation of the ratio (the peak area of analyte/the peak area of isotope). In our investigation, impact factors of this variation were studied in the extraction solution of milk powder using three mass spectrometers coupled with different ion source designs, and deuterium-labeled chloramphenicol (D5-CAP) was used as the internal standard. ME from mobile phases, sample solvents, pre-treatment methods, sample origins and instruments was evaluated, and its impact on the results of IDMS was assessed using the IDMS correction factor (θ). Our data showed that the impact of ME of mobile phase on the correction factor was significantly greater than that of sample solvent. Significant ion suppression and enhancement effects were observed in different pre-treated sample solutions. The IDMS correction factor in liquid–liquid extraction (LLE) and molecular imprinted polymer (MIP) extract with different instruments was greater or less 1.0, and the IDMS correction factor in hydrophilic lipophilic balance (HLB) and mix-mode cation exchange (MCX) extract with different instruments was all close to 1.0. To the instrument coupled with different ion source design, the impact of ME on IDMS quantitative results was

    在一定意义上,效率与公平理论是唯物史观的基本内涵或一条主线。在经济学和唯物史观的不同视域中,效率和公平具有不同的规定性。在唯物史观中,效率是指生产力的发展,公平是指分配公平或分配正义。经济关系中的公平分配是最基本的维度,而效率又包含着人的发展和经济增长两个基本维度,其中人的发展具有根本性,是最终价值。效率与公平都与人的发展呈现一种直接相关或正相关的关系。效率与公平不构成一个矛盾,不形成一种冲突性关系,而是以人的发展为目标的交响。人的发展效率是衡量和界定效率与公平关系的根本准则。在人的发展问题上,效率和公平都是第一性的,不存在谁先谁后和彼此冲突的问题。%In a certain sense, efficiency and equity theory is the basic connotation of historical materialism, or a main line. From the different view of the domain of economics and historical materialism, efficiency and equity have different requirements. Under historical materialism, efficiency refers to the development of productivity, fairness refers to distributive justice or distributive justice. Equitable distribution of economic relations is the most basic dimensions of efficiency but also contains human development and economic growth of the two basic dimensions, in which human development is fundamental to the final value. Efficiency, equity and human development, preseuts a direct or positive correlation relationship. Efficiency and fairness does not eonstitute a contradiction, do not form a eonflieting relationship, and both eontribute to the target of human development. The effieiency of human development is the fundamental eriteria to measure and define the relationship between efficiency and equity. In human development, efficiency and fairness are primary, there is the issue of precedence and eonfliet.

    Antibody screening tests were performed in 29 unsensitized pregnant women after antepartum Rh immune prophylaxis, using the indirect Coombs test (ICT) and a more sensitive ID-microtyping-system (IDM). With the ICT, anti-D antibodies were detected in 85% for at least 4 weeks and at most 8 weeks after immunisation. The maximum titer was 1:8. With the IDM, 97% showed antibodies against 'D' for at least 4 weeks and at most 11 weeks with a maximum of 1:16. The IDM titer was always 1 to 3 steps more sensitive than the ICT. After postpartum Rh immune prophylaxis, anti-D titers were again positive in many of the patients (ICT: 42%; IDM: 60%). In conclusion, it is nearly always possible to measure antibodies against 'D' after antepartum Rh immune prophylaxis and IDM was superior in comparison to ICT. However, maternal isoimmunisation to the rhesus antigen cannot be excluded for sure and patients have then to be controlled. As isoimmunisation could not be confirmed in any of our patients, postpartum Rh immune prophylaxis has to be administered even after detection of an antibody titer against 'D' after antepartum Rh prophylaxis.

  10. The Research of Car-Following Model Based on Real-Time Maximum Deceleration

    2015-01-01

    Full Text Available This paper is concerned with the effect of real-time maximum deceleration in car-following. The real-time maximum acceleration is estimated with vehicle dynamics. It is known that an intelligent driver model (IDM can control adaptive cruise control (ACC well. The disadvantages of IDM at high and constant speed are analyzed. A new car-following model which is applied to ACC is established accordingly to modify the desired minimum gap and structure of the IDM. We simulated the new car-following model and IDM under two different kinds of road conditions. In the first, the vehicles drive on a single road, taking dry asphalt road as the example in this paper. In the second, vehicles drive onto a different road, and this paper analyzed the situation in which vehicles drive from a dry asphalt road onto an icy road. From the simulation, we found that the new car-following model can not only ensure driving security and comfort but also control the steady driving of the vehicle with a smaller time headway than IDM.

    Choosing an option increases a person’s preference for that option. This phenomenon, called choice-based learning (CBL), has been investigated separately in the contexts of internally guided decision-making (IDM, e.g., preference judgment), for which no objectively correct answer exists, and externally guided decision making (EDM, e.g., perceptual decision making), for which one objectively correct answer exists. For the present study, we compared decision making of these two types to examine differences of underlying neural processes of CBL. As IDM and EDM tasks, occupation preference judgment and salary judgment were used, respectively. To compare CBL for the two types of decision making, we developed a novel measurement of CBL: decision consistency. When CBL occurs, decision consistency is higher in the last-half trials than in first-half trials. Electroencephalography (EEG) data have demonstrated that the change of decision consistency is positively correlated with the fronto-central beta–gamma power after response in the first-half trials for IDM, but not for EDM. Those results demonstrate for the first time the difference of CBL between IDM and EDM. The fronto-central beta–gamma power is expected to reflect a key process of CBL, specifically for IDM.

  16. Determination of Trace Iron in Red Wine by Isotope Dilution Mass Spectrometry Using Multiple-Collector Inductively Coupled Plasma Mass Spectrometry

    International Nuclear Information System (INIS)

    This paper introduces determination of trace iron in red wine certified reference material by isotope dilution mass spectrometry (IDMS) method using a multiplecollector inductively coupled plasma mass spectrometry, equipped with a hexapole collision cell. The measurement procedure of iron isotopic abundance ratios was deeply researched. Reduced polyatomic ion interferences to iron isotopes ion by collision reaction using Ar and H2 gas, high precise isotopic abundance ratios were achieved. Two relative measurement methods (ICP-MS and ICP-OES) were used to analyze trace iron in red wine. The results are compared with IDMS results, which indicate that they are accordant. The uncertainty analyses include each uncertainty factor in whole experiment and the uncertainty of used certified reference material and it shows that the procedure blank is not neglectable to detect limit and precision of the method. The establishment of IDMS method for analysis of trace iron in red wine supports the certification of certified reference materials. (authors)

    2015-01-01

    The Inert Doublet Model (IDM) is one of the simplest extensions of the Standard Model that can provide a viable dark matter (DM) candidate. Despite its simplicity, it predicts a versatile phenomenology both for cosmology and for the Large Hadron Collider. We briefly summarize the status of searches for IDM dark matter in direct DM detection experiments and the LHC, focusing on the impact of the latter on the model parameter space. In particular, we discuss the consequences of the Higgs boson discovery as well as those of searches for dileptons accompanied by missing transverse energy during the first LHC Run and comment on the prospects of probing some of the hardest to test regions of the IDM parameter space during the 13 TeV Run.

    A Monte Carlo (MC) model of a mechanically-cooled High Purity Germanium detection system IDM-200-V™ manufactured by ORTEC® was created, optimized and validated within the scope of the Joint Research Project ENV57 ``Metrology for radiological early warning networks in Europe''. The validation was performed for a planar source homogeneously distributed on a filter placed on top of the detector end cap and for point sources positioned farther from the detector by comparing simulated full-energy peak (FEP) detection efficiencies with the ones measured with two or three different pieces of the IDM detector. True coincidence summing correction factors were applied to the measured FEP efficiencies. Relative differences of FEP efficiencies laid within 8% that is fully satisfactory for the intended use of the detectors as instruments for airborne radioactivity measurement in field-stations. The validated MC model of the IDM-200-V™ detector is now available for further MC calculations planned in the ENV57 project.

    Mifamurtide is a conjugate of muramyl tripeptide linked to dipalmitoyl phosphatidyl ethanolamine; the phospholipid facilitates incorporation of the peptide into liposomes. The agent stimulates macrophages to seek out and destroy cancer cells. The compound was originated by Novartis (formerly CIBA-Geigy), and is being developed by IDM Pharma for osteosarcoma. Mifamurtide is being reviewed by regulatory authorities in the US and EU for this indication.CIBA-Geigy originally developed mifamurtide in the early 1980s and the agent was subsequently outlicensed to Jenner Biotherapies in the 1990s. IDM Pharma acquired the rights to the drug from Jenner in April 2003.IDM and Genesis Pharma have entered into an exclusive licensing and marketing agreement for mifamurtide in South East Europe. Under the agreement terms, IDM will receive an upfront fee from Genesis, as well as milestone payments on reaching certain sales levels in the territory. Medison Pharma signed an agreement with IDM Pharma for the sales and marketing of mifamurtide in Israel. IDM will receive an upfront license fee from Medison and will be entitled to receive a milestone payment upon regulatory approval of the agent in Israel, as well as royalties on net sales.IDM outlicensed exclusive marketing rights for mifamurtide in the UK and Ireland to Cambridge Laboratories in June 2005. In exchange, IDM is entitled to an upfront license fee and milestone payments prior to launch, as well as royalties calculated on product sales.Previously, Chiron Vaccines (a joint venture between Novartis and Chiron formed in 1995) investigated mifamurtide as an adjuvant in HIV gp120 vaccine; however, development has been discontinued.IDM Pharma will purchase approximately 7.1 million shares of its common stock to raise approximately $US23.5 million in net proceeds.

  2. Seeding supermassive black holes with a non-vortical dark-matter subcomponent

    Sawicki, Ignacy; Valkenburg, Wessel

    2013-01-01

    A perfect irrotational fluid with the equation of state of dust, Irrotational Dark Matter (IDM), is incapable of virializing and instead forms a cosmoskeleton of filaments with supermassive black holes at the joints. This stark difference from the standard cold dark matter (CDM) scenario arises because IDM must exhibit potential flow at all times, preventing shell-crossing from occurring. This scenario is applicable to general non-oscillating scalar-field theories with a small sound speed. Our model of combined IDM and CDM components thereby provides a solution to the problem of forming the observed billion-solar-mass black holes at redshifts of six and higher. In particular, as a result of the reduced vortical flow, the growth of the black holes is expected to be more rapid at later times as compared to the standard scenario.

    2015-12-01

    Full Text Available Background: Infants of diabetic mothers (IDM is a critical issue in pediatrics, which is regarded as a major risk factor for birth trauma, respiratory distress syndrome (RDS, birth asphyxia, transient tachypnea of the newborn (TTN and jaundice. IDM is also a risk factor for microvascular (e.g., ocular and renal complications and macrovascular complications (e.g., cerebrovascular accident, atherosclerosis and cardiovascular complications. Lipids are a heterogeneous group of hydrophobic organic molecules which can be extracted from tissues using non-polar solvents. Lipids, due to their hydrophobic property, are mainly found in membranes enclosing various cell organelles. Diabetes mellitus management with insulin (nowadays also with oral hypoglycemic medications has improved the outcomes of gestational diabetes mellitus (GDM (most infants born to diabetic mother are large for gestational age. The neonatal mortality rate in IDM is over five times higher than that of infants of non-diabetic mothers. In this study, therefore, we aimed to assess the effect of maternal diabetes on cord serum lipid profile. Methods: This prospective (case-control study was carried out on 60 infants born in Al-Zahra teaching hospital during February 2014–October 2014. The study group consisted of 30 randomly chosen IDM, and the control group comprised 30 infants who were born to healthy mothers. Results: The results of this study demonstrated that there are significant differences between IDM and infants of healthy mothers regarding lipid profile and birth weight. Conclusion: This study confirms that cord serum lipid profile (serum cholesterol, serum triglycerides and low-density lipoprotein is higher at birth in IDM. Moreover, this study shows a significant association between lipid profile and body weight.

  4. Instantaneous-to-daily GPP upscaling schemes based on a coupled photosynthesis-stomatal conductance model: correcting the overestimation of GPP by directly using daily average meteorological inputs.

    Daily canopy photosynthesis is usually temporally upscaled from instantaneous (i.e., seconds) photosynthesis rate. The nonlinear response of photosynthesis to meteorological variables makes the temporal scaling a significant challenge. In this study, two temporal upscaling schemes of daily photosynthesis, the integrated daily model (IDM) and the segmented daily model (SDM), are presented by considering the diurnal variations of meteorological variables based on a coupled photosynthesis-stomatal conductance model. The two models, as well as a simple average daily model (SADM) with daily average meteorological inputs, were validated using the tower-derived gross primary production (GPP) to assess their abilities in simulating daily photosynthesis. The results showed IDM closely followed the seasonal trend of the tower-derived GPP with an average RMSE of 1.63 g C m(-2) day(-1), and an average Nash-Sutcliffe model efficiency coefficient (E) of 0.87. SDM performed similarly to IDM in GPP simulation but decreased the computation time by >66%. SADM overestimated daily GPP by about 15% during the growing season compared to IDM. Both IDM and SDM greatly decreased the overestimation by SADM, and improved the simulation of daily GPP by reducing the RMSE by 34 and 30%, respectively. The results indicated that IDM and SDM are useful temporal upscaling approaches, and both are superior to SADM in daily GPP simulation because they take into account the diurnally varying responses of photosynthesis to meteorological variables. SDM is computationally more efficient, and therefore more suitable for long-term and large-scale GPP simulations.

  9. Determination of the rare earth elements in marine pore waters and associated sediments

    International Nuclear Information System (INIS)

    Accurate and precise determinations of natural levels of rare earth elements (R.E.E.) in sea water and pore water are highly reliant upon the size and variability of the analytical blank, the method for determining the yield, and, to a lesser extent, the inherent precision of the instrument used. Isotope dilution mass spectrometry (IDMS) together with ultra-clean room techniques has been successfully used in the determinations of rare earth elements in pore waters. Simultaneous multi-element analysis by inductively coupled plasma atomic emission spectrometry (ICP) provides an alternative to IDMS for a rapid determination of R.E.E. in sediments. (author)

However, it is often difficult for older adults to make an informed decision about adopting sensor technologies.Objective To explore Bruce’s framework of informed decision making (IDM for in-home use of sensor technologies in community-dwelling elders.Method The IDM framework guided development of a semi-structured interview. A theory-driven coding approach was used for analysis.Results Participants supported most of the elements of the framework, but not all aspects of each element were addressed. Perceived usefulness of technologies was identified as an area for framework extension.Conclusion This paper provides useful information for health care professionals to consider how to enhance IDM of older adults regarding the use of sensor technologies. The results also illuminate elements of the IDM framework that may be critical to facilitating independent living for older adults.

    Full Text Available David S Cobden1, Louis W Niessen2, Frans FH Rutten1, W Ken Redekop11Department of Health Policy and Management, Section of Health Economics – Medical Technology Assessment (HE-MTA, Erasmus MC, Erasmus University Rotterdam, The Netherlands; 2Department of International Health, Johns Hopkins University School of Public Health, Johns Hopkins Medical Institutions, Baltimore, MD, USAAims: While strong correlations exist between medication adherence and health economic outcomes in type 2 diabetes, current economic analyses do not adequately consider them. We propose a new approach to incorporate adherence in cost-effectiveness analysis.Methods: We describe a theoretical approach to incorporating the effect of adherence when estimating the long-term costs and effectiveness of an antidiabetic medication. This approach was applied in a Markov model which includes common diabetic health states. We compared two treatments using hypothetical patient cohorts: injectable insulin (IDM and oral (OAD medications. Two analyses were performed, one which ignored adherence (analysis 1 and one which incorporated it (analysis 2. Results from the two analyses were then compared to explore the extent to which adherence may impact incremental cost-effectiveness ratios.Results: In both analyses, IDM was more costly and more effective than OAD. When adherence was ignored, IDM generated an incremental cost-effectiveness of $12,097 per quality-adjusted life-year (QALY gained versus OAD. Incorporation of adherence resulted in a slightly higher ratio ($16,241/QALY. This increase was primarily due to better adherence with OAD than with IDM, and the higher direct medical costs for IDM.Conclusions: Incorporating medication adherence into economic analyses can meaningfully influence the estimated cost-effectiveness of type 2 diabetes treatments, and should therefore be ­considered in health care decision-making. Future work on the impact of adherence on health

    Background Excellent communication between surgeons and patients is critical to helping patients to make informed decisions and is a key component of both high quality of care and patient satisfaction. Understanding racial disparities in communication is essential to provide quality care to all patients. Objective To examine the content and process of informed decision-making (IDM) between orthopedic surgeons and elderly white versus African American patients. To assess the association of race and patient satisfaction with surgeon communication. Research Design Analysis of audiotape recordings of office visits between orthopedic surgeons and patients. Participants Eighty-nine orthopedic surgeons and 886 patients age 60 years or older in Chicago, Illinois. Methods Tapes were analyzed by coders for content using 9 elements of IDM and for process using 4 global ratings of the relationship-building component of communication (responsiveness, respect, listening, and sharing). Ratings by race were compared using χ2 analysis. Patients completed a questionnaire rating satisfaction with surgeon communication and the visit overall. Logistic analysis was used to assess the effect of race on satisfaction. Results Overall there were practically no significant differences in the content of the 9 IDM elements based on race. However, coder ratings of relationship were higher on 3 of 4 global ratings (responsiveness, respect, and listening) in visits with white patients compared with African American patients (P < 0.01). Patient ratings of communication and overall satisfaction with the visit were significantly higher for white patients. Conclusions The content of IDM conversations does not differ by race. Yet differences in the process of relationship building and in patient satisfaction ratings were clearly present. Efforts to enhance cultural communication competence of surgeons should emphasize the skills of building relationships with patients in addition to the content of

    Maternal diabetes mellitus is recognized to be a predisposing factor to thrombosis in the neonate. In the adult with diabetes, abnormalities in the metabolism of AA by the platelet and vessel wall occur, which result in an increase in proaggregatory platelet thromboxane A2. A decrease in antiaggregatory vascular PGI2 has been demonstrated in the diabetic rat, although conclusive proof of a similar abnormality is lacking in humans. We evaluated vascular AA metabolism in 10 IDM (groups II and III comparison to 20 control neonates of gestational ages 32 to 40 weeks (group I). Mean uptakes of labeled AA into vascular tissue of both controls and IDM were similar. The conversion of (14C) AA to 6-keto-PGF1 alpha was not dependent on gestational age (r . 0.223) in the control neonates, with a mean value of 5.2% +- 1.3 (1 S.D.). A marked decrease (p less than 0.001) in 6-keto-PGF1 alpha formation to 1.7% +- 0.3 was found in the group II IDM of mothers with poor diabetic control (HbA1c . 9.3% +- 0.5). In the group III neonates whose mothers had normal HBA1c levels (6.1% +- 0.9), 6-keto-PGF1 alpha production was normal at 4.9% +- 0.8. Although no correlation between maternal fasting blood glucose and neonatal 6-keto-PGF1 alpha was demonstrable, a significant inverse correlation (r . 0.872; p less than 0.02) was observed between maternal HbA1c levels and the conversion of AA to 6-keto-PGF1 alpha in the vascular tissues of the IDM. It appear possible that abnormalities in platelet-vascular AA metabolism may play an etiologic role in the vascular complications present in some IDM.

    Full Text Available Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Cloud computing is a paradigm shift following the shift from mainframe to client–server in the early 1980s. Cloud computing can be defined as accessing third party software and services on web and paying as per usage. It facilitates scalability and virtualized resources over Internet as a service providing cost effective and scalable solution to customers. Cloud computing has evolved as a disruptive technology and picked up speed with the presence of many vendors in cloud computing space. The evolution of cloud computing from numerous technological approaches and business models such as SaaS, cluster computing, high performance computing, etc., signifies that the cloud IDM can be considered as a superset of all the corresponding issues from these paradigms and many more. In this paper we will discuss Life cycle management, Cloud architecture, Pattern in Cloud IDM, Volatility of Cloud relations.

    Intensive competition of intellectual property, easy development of agrochemical resistance, and stricter regulations of environmental concerns make the successful rate for agrochemical discovery extremely lower using traditional agrochemical discovery methods. Therefore, there is an urgent need to find a novel approach to guide agrochemical discovery with high efficiency to quickly keep pace with the changing market. On the basis of these situations, here we summarize the intermediate derivatization method (IDM) between conventional methods in agrochemicals and novel ones in pharmaceuticals. This method is relatively efficient with short time in discovery phase, reduced cost, especially good innovated structure, and better performance. In this paper, we summarize and illustrate "what is the IDM" and "why to use" and "how to use" it to accelerate the discovery of new biologically active molecules, focusing on agrochemicals. Furthermore, we display several research projects in our novel agrochemical discovery programs with improved success rate under guidance of this strategy in recent years. PMID:25517210

  5. THE VERTICAL THERMAL STRUCTURE OF THE INDIAN OCEAN DIPOLE MODE FROM WOCE DATA

    2001-01-01

    The Dipole Mode in tropical Indian Ocean (DMI) is a newly verified independent internal mode of atmosphere-ocean system in Indian Ocean. Its surface manifestation is illustrated in detail with the aid of the historical data sets. But relatively few is known about its vertical characteristics. Here the vertical thermal structure of DMI is analyzed using the newly released WOCE GLOBAL DATA (V2.0). Attention is focused on the comparison of the abnormal upper ocean thermal structure along one section with the normal state in year 1990 respectively in two cases: in year 1994 when there was IDM but no E1 Nino and in year 1997 when there were DMI and also E1 Nino. This may shed light on the further theoretical and numerical study of IDM.

    2009-01-01

    A novel in-pipe micro robot providing stable and accurate locomotion inside a tubular structure with diameters ranging from 16 mm to 18 mm is presented in this paper. Driven by impulsive voltages, deflections of the piezoelectric bimorphs are generated and then converted into translational locomotion by the principle of the Impact Drive Mechanism (IDM). Theoretical analysis of the proposed system is performed based on a simplified mechanical model. Then dynamic simulations of the dynamic behavior are performed. Finally, an experiment is conducted to investigate the moving ability of this device. The results demonstrate that a maximum translational velocity of 3.5 mm/s can be obtained under an impulsive driving voltage with peak value at 50 V and frequency of 1100 Hz. Both theoretical analysis and experimental trials prove that the principle of IDM actuated by piezoelectric bimorphs is feasible and robust for achieving accurate locomotion of the micro robot in pipes with diameters of less than 20 mm.

  4. Indomethacin nanocrystals prepared by different laboratory scale methods: effect on crystalline form and dissolution behavior

    International Nuclear Information System (INIS)

    The objective of this study is to select very simple and well-known laboratory scale methods able to reduce particle size of indomethacin until the nanometric scale. The effect on the crystalline form and the dissolution behavior of the different samples was deliberately evaluated in absence of any surfactants as stabilizers. Nanocrystals of indomethacin (native crystals are in the γ form) (IDM) were obtained by three laboratory scale methods: A (Batch A: crystallization by solvent evaporation in a nano-spray dryer), B (Batch B-15 and B-30: wet milling and lyophilization), and C (Batch C-20-N and C-40-N: Cryo-milling in the presence of liquid nitrogen). Nanocrystals obtained by the method A (Batch A) crystallized into a mixture of α and γ polymorphic forms. IDM obtained by the two other methods remained in the γ form and a different attitude to the crystallinity decrease were observed, with a more considerable decrease in crystalline degree for IDM milled for 40 min in the presence of liquid nitrogen. The intrinsic dissolution rate (IDR) revealed a higher dissolution rate for Batches A and C-40-N, due to the higher IDR of α form than γ form for the Batch A, and the lower crystallinity degree for both the Batches A and C-40-N. These factors, as well as the decrease in particle size, influenced the IDM dissolution rate from the particle samples. Modifications in the solid physical state that may occur using different particle size reduction treatments have to be taken into consideration during the scale up and industrial development of new solid dosage forms.

    Patients with COPD experience respiratory symptoms, impairments of daily living and recurrent exacerbations. The aim of integrated disease management (IDM) is to establish a programme of different components of care (ie, self-management, exercise, nutrition) in which several healthcare providers (ie, nurses, general practitioners, physiotherapists, pulmonologists) collaborate to provide efficient and good quality of care. The aim of this Cochrane systematic review was to evaluate the effectiveness of IDM on quality of life, exercise tolerance and exacerbation related outcomes. Searches for all available evidence were carried out in various databases. Included randomised controlled trials (RCTs) consisted of interventions with multidisciplinary (≥2 healthcare providers) and multitreatment (≥2 components) IDM interventions with duration of at least 3 months. Two reviewers independently searched, assessed and extracted data of all RCTs. A total of 26 RCTs were included, involving 2997 patients from 11 different countries with a follow-up varying from 3 to 24 months. In all 68% of the patients were men, with a mean age of 68 years and a mean forced expiratory volume in 1 s (FEV1) predicted value of 44.3%. Patients treated with an IDM programme improved significantly on quality of life scores and reported a clinically relevant improvement of 44 m on 6 min walking distance, compared to controls. Furthermore, the number of patients with ≥1 respiratory related hospital admission reduced from 27 to 20 per 100 patients. Duration of hospitalisation decreased significantly by nearly 4 days.

    The objective of this study is to select very simple and well-known laboratory scale methods able to reduce particle size of indomethacin until the nanometric scale. The effect on the crystalline form and the dissolution behavior of the different samples was deliberately evaluated in absence of any surfactants as stabilizers. Nanocrystals of indomethacin (native crystals are in the {gamma} form) (IDM) were obtained by three laboratory scale methods: A (Batch A: crystallization by solvent evaporation in a nano-spray dryer), B (Batch B-15 and B-30: wet milling and lyophilization), and C (Batch C-20-N and C-40-N: Cryo-milling in the presence of liquid nitrogen). Nanocrystals obtained by the method A (Batch A) crystallized into a mixture of {alpha} and {gamma} polymorphic forms. IDM obtained by the two other methods remained in the {gamma} form and a different attitude to the crystallinity decrease were observed, with a more considerable decrease in crystalline degree for IDM milled for 40 min in the presence of liquid nitrogen. The intrinsic dissolution rate (IDR) revealed a higher dissolution rate for Batches A and C-40-N, due to the higher IDR of {alpha} form than {gamma} form for the Batch A, and the lower crystallinity degree for both the Batches A and C-40-N. These factors, as well as the decrease in particle size, influenced the IDM dissolution rate from the particle samples. Modifications in the solid physical state that may occur using different particle size reduction treatments have to be taken into consideration during the scale up and industrial development of new solid dosage forms.

  20. Classical scale invariance in the inert doublet model

    CERN Document Server

    Plascencia, Alexis D

    2015-01-01

    The inert doublet model (IDM) is a minimal extension of the Standard Model (SM) that can account for the dark matter in the universe. Naturalness arguments motivate us to study whether the model can be embedded into a theory with dynamically generated scales. In this work we study a classically scale invariant version of the IDM with a minimal hidden sector, which has a $U(1)_{\\text{CW}}$ gauge symmetry and a complex scalar $\\Phi$. The mass scale is generated in the hidden sector via the Coleman-Weinberg (CW) mechanism and communicated to the two Higgs doublets via portal couplings. Since the CW scalar remains light, acquires a vacuum expectation value and mixes with the SM Higgs boson, the phenomenology of this construction can be modified with respect to the traditional IDM. We analyze the impact of adding this CW scalar and the $Z'$ gauge boson on the calculation of the dark matter relic density and on the spin-independent nucleon cross section for direct detection experiments. Finally, by studying the RG ...

    The pathophysiology of gastritis involves an imbalance between gastric acid attack and mucosal defence. In addition, the gastric mucosal injury results in adenosine triphosphate (ATP) depletion leading to mitochondrial dysfunction. Several studies have shown the association of mitochondrial disorders with gastrointestinal dysfunction. In the present study, we investigated the activity of mitochondrial respiratory chain complexes activity in the stomach of rats with gastritis induced by indomethacin (IDM) and treated with omeprazole (OM), N-acetylcysteine (NAC) and the gastrin-releasing peptide receptor (GRPR) antagonist RC-3095. Adult male Wistar rats were pre-treated for 7 days with OM, NAC, RC-3095, combination of OM plus RC-3095, OM plus NAC and water (control). The animals were then submitted to fasting for 24 hr; IDM was administered. The rats were killed 6 hr later, and the stomachs were used for evaluation of macroscopic damage and respiratory chain activity. Our results showed that complex I and IV activities were not affected by administration of IDM. On the other hand, complex II and III activities were inhibited. In addition, OM plus RC-3095 and OM plus NAC did not reverse complex II activity inhibition. However, the complex III activity inhibition was reversed only with the combined use of OM plus RC-3095 and OM plus NAC. Our results are in agreement with previous studies indicating mitochondrial dysfunction in the pathophysiology of gastrointestinal tract disease and we suggest that GRPR antagonism might be a novel therapeutic strategy in gastritis.

  2. Application of isotope dilution method for measuring bioavailability of organic contaminants sorbed to dissolved organic matter (DOM)

    Natural waters such as surface water and sediment porewater invariably contain dissolved organic matter (DOM). Association of strongly hydrophobic contaminants (HOCs) with DOM leads to decreased toxicity and bioavailability, but bioavailability of DOM-sorbed HOCs is difficult to measure. Current methods to estimate bioavailability of HOCs in water are based on only the freely dissolved concentration (C{sub free}). The ignorance of the exchangeable fraction of HOCs sorbed on DOM may result in an underestimation of the toxicity potential of HOCs to aquatic organisms. Here we explore the applicability of an isotope dilution method (IDM) to measuring the desorption fraction of DOM-sorbed pyrene and bifenthrin and determining their exchangeable pool (E) as an approximation of bioavailability. E values, expressed as percentage of the total concentration, ranged between 0.80 and 0.92% for pyrene and 0.74 and 0.85% for bifenthrin, depending primarily on the amount of chemical in the freely dissolved form. However, between 34 and 78% of the DOM-sorbed pyrene was exchangeable. This fraction ranged between 23% and 82% for bifenthrin. The ability of IDM to predict bioavailability was further shown from a significant relationship (r{sup 2} > 0.72, P < 0.0001) between E and bioaccumulation into Daphnia magna. Therefore, IDM may be used to improve the bioavailability measurement and risk assessment of HOCs in aquatic systems.

  3. Exploring the Inert Doublet Model through the dijet plus missing transverse energy channel at the LHC

    2016-01-01

    In this study of the Inert Doublet Model (IDM), we propose that the dijet + missing transverse energy channel at the Large Hadron Collider will be an effective way of searching for the scalar particles of the IDM. This channel receives contributions from gauge boson fusion, and $t-$channel production, along with contributions from $H^+$ associated production. We find that, for $\\sqrt{s} =13$ TeV with moderate luminosity, this channel has the potential to probe the IDM in the mass range of up to about 150 GeV, complementing other leptonic channel searches. We perform the analysis including study of the Standard Model (SM) background, and optimise the selection criteria employing suitable cuts on the kinematic variables to maximise the signal significance. In a scenario with light dark matter of mass about 65 GeV, charged Higgs in the intermediate mass range of around 150 GeV could be probed with a luminosity of about 500 fb$^{-1}$, whereas higher masses around 200 and 300 GeV require about 1 and 2 ab$^{-1}$ lu...

    The dielectrophoresis (DEP) interactions of a few particles in a uniform two-dimensional (2D) electrical field have well been studied by Maxwell stress tensor (MST) method. Multiple particle interactions in three-dimensional (3D) electrical field are investigated in this work using iterative dipole moment (IDM) method which is an analytic algorithm without complicated numerical computations to solve for electrical field. The interactive DEP forces of particles calculated by IDM are found to be well agreed with those of MST method and much simple to implement. Using IDM method, a series of examples of multiple particles interactions and particle chains in a 3D uniform DC electrical field is presented. Randomly distributed similar dense particles (either all positive DEP (pDEP) or all negative DEP (nDEP) particles) in 3D uniform electrical field can generally form chains in lines parallel to the electrical field, except the case that all similar particles are in a plane perpendicular to the electrical field where the particles repel each other and move away in the plane. Randomly distributed dissimilar dense particles (mixture of pDEP and nDEP particles) can form (1) chains in lines, (2) clusters in a plane or (3) 3D groups. The chains, clusters and groups are of staggered arrangements of pDEP and nDEP particles, which are perpendicular to the electrical field.

    2010-10-20

    This final report details the components, functionality, costs, schedule and benefits of developing an Integrated Distribution Management System (IDMS) for power distribution system operation. The Distribution Automation (DA) and Supervisory Control and Data Acquisition (SCADA) systems used by electric power companies to manage the distribution of electric power to retail energy consumers are vital components of the Nation’s critical infrastructure. Providing electricity is an essential public service and a disruption in that service, if not quickly restored, could threaten the public safety and the Nation’s economic security. Our Nation’s economic prosperity and quality of life have long depended on the essential services that utilities provide; therefore, it is necessary to ensure that electric utilities are able to conduct their operations safely and efficiently. A fully integrated technology of applications is needed to link various remote sensing, communications and control devices with other information tools that help guide Power Distribution Operations personnel. A fully implemented IDMS will provide this, a seamlessly integrated set of applications to raise electric system operating intelligence. IDMS will enhance DA and SCADA through integration of applications such as Geographic Information Systems, Outage Management Systems, Switching Management and Analysis, Operator Training Simulator, and other Advanced Applications, including unbalanced load flow and fault isolation/service restoration. These apps are capable of utilizing and obtaining information from appropriately installed DER, and by integrating disparate systems, the Distribution Operators will benefit from advanced capabilities when analyzing, controlling and operating the electric system.

  7. Trace analysis of U, Th and other heavy metals in high purity aluminium with isotope dilution mass spectrometry

    International Nuclear Information System (INIS)

    A method for the determination of very low concentrations of U, Th, Fe, Zn, Tl, Cd, Cu and Ag in high purity aluminium with isotope dilution mass spectrometry (IDMS) is developed using a compact and cost-efficient thermal ionization quadrupole mass spectrometer. The detection limits obtained are (in ng/g):U=0.018, Th=0.06, Fe=82, Zn=86, Tl=0.2, Cd=4, Cu=1, Ag=2.6. By this method it is possible to determine the α-emitters U and Th in aluminium down to the sub-ng/g level with good precision of 0.4-10% and 0.5-5%, respectively. The results should also be accurate because IDMS is a reliable analytical method. The dissolution of aluminium is carried out by aqua regia followed by the trace/matrix separation and the isolation of the trace elements by anion exchange chromatography (U, Th, Zn, Tl, Cd), electrodeposition (Cu, Ag) and extraction (Fe). Different aluminium samples are analysed by IDMS and the results are compared with those of other methods. (orig.)

    In the past isotope dilution mass spectrometry (IDMS) has usually been applied using the formation of positive thermal ions of metals. Especially in calibrating other analytical methods and for the certification of standard reference materials this type of IDMS became a routine method. Today, the progress in this field lies in the determination of ultra trace amounts of elements, e.g. of heavy metals in Antarctic ice and in aerosols in remote areas down to the sub-pg g-1 and sub-pg m-3 levels respectively, in the analysis of uranium and thorium at concentrations of a few pg g-1 in sputter targets for the production of micro- electronic devices or in the determination of sub-picogram amounts of230Th in corals for geochemical age determinations and of226Ra in rock samples. During the last few years negative thermal ionization IDMS has become a frequently used method. The determination of very small amounts of selenium and technetium as well as of other transition metals such as vanadium, chromium, molybdenum and tungsten are important examples in this field. Also the measurement of silicon in connection with a re-determination of Avogadro's number and osmium analyses for geological age determinations by the Re/Os method are of special interest. Inductively-coupled plasma mass spectrometry is increasingly being used for multi-element analyses by the isotope dilution technique. Determinations of heavy metals in samples of marine origin are representative examples for this type of multi-element analysis by IDMS. Gas chromatography-mass spectrometry systems have also been successfully applied after chelation of metals (for example Pt determination in clinical samples) or for the determination of volatile element species in the environment, e.g. dimethyl sulfide. However, IDMS--specially at low concentration levels in the environment--seems likely to be one of the most powerful analytical methods for speciation in the future. This has been shown, up to now, for species of

    2015-01-01

    Full Text Available The opus of contemporary Serbian composer Milorad Marinković (b. 1976, which encompasses works of choral, chamber, concertante and symphony music, leans towards classical forms of artistic music, Serbian folklore music, and Serbian Orthodox church chant. This paper deals with pieces composed for larger instrumental ensembles: Herojska uvertira (Heroic Overture for symphony orchestra, Psalmodija (Psalmody for symphony orchestra, Koncert za klavir i orkestar (Piano concerto and Mala opera (Little Opera for chamber ensemble (septet with prominent soloist parts of flute and clarinet. Special attention is placed on different procedures used by Marinković to accomplish wholeness and integration of the musical tissue. This paper observes these pieces as examples of religious music, having in mind the composer’s own understanding of the notion. Among common characteristics of the observed works that justify this point of view are specific single movement forms and the prominent role of main thematic materials, a cyclic principle, and programmatic elements. References to Serbian church chant observed in Marinković’s instrumental works are also discussed, especially in parallel with the analogue procedures used by Ljubica Marić (1909- 2003, one of the composer’s role models. Although Marinković’s works for instrumental ensembles do not fall into the category of spiritual music in its narrow sense (as defined by the composer himself, in this paper they are nevertheless considered as “spiritual” in a broader sense, as an expression of the composer’s desire to spiritualize his entire artistic output.

    Full Text Available In privileging music as a focus for applied ecology, the goal of this essay is to deepen perspectives on the musical representation of land in an age of complex environmental challenge. As the metaphor driving public narration of environmental crises, the notion of Earth as our home—signified by the prefix “eco”—brings with it a critical expectation for the musical academy to retreat from bland talk about a “sense of place.” Based on the premise that damaged ecologies are a matter of concern to many people, Indigenous and Settler; and building on the late Val Plumwood’s theory of “shadow” or “denied” places (Australian Humanities Review 44, 2008, the author introduces Within Our Reach: A Symphony of the Port River Soundscapes by anti-elitist South Australian composer Chester Schultz (b. 1945. Inspired by the tradition of R. Murray Schafer’s performances for outdoor sites, Schultz predicated this niche symphony on the noise-polluting defoliation of Adelaide’s “wetland wonder,” the Old Port Reach. Presented as a series of narrative soundscapes, the symphony harnesses the power of music, including popular genres, to engender a sense of local “belonging” to the Port. In an ecological subtext an Indigenous Elder sings in the re-awakening language of the Kaurna people who, in 1890, were evicted from their “nourishing terrain” (terminology after Rose, 1996 by the CSR Sugar Refinery. Schultz’s ethical musical representation of local oral, natural and industrial history generates a benchmark opus for what shadow place composition might sound like in the modern global city.

  12. Isotope dilution mass spectrometry of microelectronically relevant heavy metal traces in high-purity cobalt

    International Nuclear Information System (INIS)

    Because cobalt and its silicides are increasingly used in microelectronic devices, an isotope dilution mass spectrometric (IDMS) method has been developed for trace analysis of relevant heavy metals (U, Th, Fe, Zn, Tl, and Cd) in high-purity cobalt. The measurements of the isotope ratios were carried out with a small thermal ionization quadrupole mass spectrometer by producing positive thermal ions in a single- or double-filament ion source. For the trace/matrix separation and the isolation of the different heavy metals, anion-exchange chromatography and an extraction method for iron were applied. The detection limits obtained were (in ng/g): U = 0.007, Th = 0.017, Tl = 0.06, Cd = 1, Zn = 8, and Fe = 11, which demonstrates that the particularly critical radioactive impurities uranium and thorium could be analysed down to the low pg/g range. Three cobalt samples of different purity were analysed with concentrations ranging from about 0.1 ng/g for U and Th in an ultra high-purity material produced for microelectronic purposes, up to about 70 μg/g for Cd in a cobalt sample with declared purity of 99.8%. Because IDMS usually results in accurate analytical results, it can be used in the future for calibration of other methods like glow discharge mass spectrometry, as could be shown by analysing one cobalt sample by both methods. IDMS can also be applied for the production of urgently needed certified standard reference materials in this important field of high technology. (orig.)

  13. Direct μ-flow injection isotope dilution ICP-MS for the determination of heavy metals in oil samples

    International Nuclear Information System (INIS)

    The determination of trace elements in oil samples and their products is of high interest as their presence significantly affects refinery processes and the environment by possible impact of their combustion products. In this context, inductively coupled plasma mass spectrometry (ICP-MS) plays an important role due to its outstanding analytical properties in the quantification of trace elements. In this work, we present the accurate and precise determination of selected heavy metals in oil samples by making use of the combination of μ-flow direct injection and isotope dilution ICP-MS (ICP-IDMS). Spike solutions of 62Ni, 97Mo, 117Sn and 206Pb were prepared in an organic solvent, mixed directly with the diluted oil samples and tested to be fit for purpose for the intended ID approach. The analysis of real samples revealed strong matrix effects affecting the ICP-MS sensitivity, but not the isotope ratio measurements, so that accurate results are obtained by ICP-IDMS. Typical relative standard deviations were about 15% for peak area and peak height measurements, whereas the isotope ratios were not significantly affected (RSD < 2%). The developed method was validated by the analysis of a metallo-organic multi-element standard (SCP-21, typically applied as a calibration standard) and the standard reference material SRM1084a (wear metals in lubricating oil). The obtained results were in excellent agreement with the certified values (recoveries between 98% and 102%), so the proposed methodology of combining μ-flow direct injection and ICP-IDMS can be regarded as a new tool for the matrix-independent, multi-element and reliable determination of trace elements in oil and related organic liquids.

    Salinity difference between seawater and river water is a sustainable energy resource that catches eyes of the public and the investors in the background of energy crisis. To capture this energy, interdisciplinary efforts from chemistry, materials science, environmental science, and nanotechnology have been made to create efficient and economically viable energy conversion methods and materials. Beyond conventional membrane-based processes, technological breakthroughs in harvesting salinity gradient power from natural waters are expected to emerge from the novel fluidic transport phenomena on the nanoscale. A major challenge toward real-world applications is to extrapolate existing single-channel devices to macroscopic materials. Here, we report a membrane-scale nanofluidic device with asymmetric structure, chemical composition, and surface charge polarity, termed ionic diode membrane (IDM), for harvesting electric power from salinity gradient. The IDM comprises heterojunctions between mesoporous carbon (pore size ∼7 nm, negatively charged) and macroporous alumina (pore size ∼80 nm, positively charged). The meso-/macroporous membrane rectifies the ionic current with distinctly high ratio of ca. 450 and keeps on rectifying in high-concentration electrolytes, even in saturated solution. The selective and rectified ion transport furthermore sheds light on salinity-gradient power generation. By mixing artificial seawater and river water through the IDM, substantially high power density of up to 3.46 W/m(2) is discovered, which largely outperforms some commercial ion-exchange membranes. A theoretical model based on coupled Poisson and Nernst-Planck equations is established to quantitatively explain the experimental observations and get insights into the underlying mechanism. The macroscopic and asymmetric nanofluidic structure anticipates wide potentials for sustainable power generation, water purification, and desalination. PMID:25137214

    About 50 000 workers are being occupationally exposed to radiation in Ukraine. Individual dosimetric monitoring (IDM) is provided by 77 dosimetry services and laboratories of very different scale with a number of monitored workers ranging from several persons to ∼9000. In the present work, the current status of personal dosimetry in Ukraine was studied. The First National Intercomparison (FNI) of the IDM labs was accompanied by a survey of the laboratory operation in terms of coverage, types of dosimetry provided, instrumentation and methodologies used, metrological support, data recording, etc. Totally, 34 laboratories responded to the FNI call, and 18 services with 19 different personal dosimetry systems took part in the intercomparison exercise providing 24 dosimeters each for blind irradiation to photons of 6 different qualities (ISO N-series X-rays, S-Cs and S-Co sources) in a dose range of 5-60 mSv. Performance of the dosimetry labs was evaluated according to ISO 14146 criteria of matching trumpet curves with H0 = 0.2 mSv. The test revealed that 8 of the 19 systems meet ISO 14146 criteria in full, 5 other labs show marginal performance and 6 laboratories demonstrated catastrophic quality of dosimetric results. Altogether, 18 participating labs provide dosimetric monitoring to 37 477 workers (about three-fourths of all occupationally exposed workers), usually on monthly (nuclear industry) or quarterly (rest of applications) basis. Of this number, 20 664 persons (55 %) receive completely adequate individual monitoring, and the number of personnel receiving IDM of inadequate quality counts 3054 persons. PMID:26979804

Estimates for other years were obtained by interpolating between 1990 (or the start-year of large-scale control efforts and 2010, and further extrapolating until 2030, such that the 2020 targets were met. The NTD disease manifestations considered in the GBD study were analyzed as either reversible or irreversible. Health impacts were assessed by comparing the results of achieving the targets with the counterfactual, construed as the health burden had the 1990 (or 2010 if higher situation continued unabated.Our calculations show that meeting the targets will lead to about 600 million averted DALYs in the period 2011-2030, nearly equally distributed between PCT and IDM-NTDs, with the health gain amongst PCT-NTDs mostly (96% due to averted disability and amongst IDM-NTDs largely (95% from averted mortality. These health gains include about 150 million averted irreversible disease manifestations (e.g. blindness and 5 million averted deaths. Control of soil-transmitted helminths accounts for one third of all averted DALYs. We conclude that the projected

    Vertebrate reproduction requires a myriad of precisely orchestrated events-in particular, the maternal production of oocytes, the paternal production of sperm, successful fertilization, and initiation of early embryonic cell divisions. These processes are governed by a host of signaling pathways. Protein kinase and phosphatase signaling pathways involving Mos, CDK1, RSK, and PP2A regulate meiosis during maturation of the oocyte. Steroid signals-specifically testosterone-regulate spermatogenesis, as does signaling by G-protein-coupled hormone receptors. Finally, calcium signaling is essential for both sperm motility and fertilization. Altogether, this signaling symphony ensures the production of viable offspring, offering a chance of genetic immortality. PMID:26430215

    Numerous epidemiological studies show the effect of increased ambient pollution. Therefore measurement networks for air quality have been installed worldwide and legislation requires the monitoring of air pollution. Besides monitoring it is also important to be able to identify, to quantify and finally to regulate the emission of distinct sources in order to improve the quality of life. Automotive vehicles are a major source of environmental pollution especially through contaminants such as CO, NOX, SOX and hydrocarbons which derive from petrol combustion, while for example Platinum Group Elements (PGE) can be present from catalytic converters. The release of PGE into the environment, however, may be damaging in terms of public health, ecological and economic interests. In order to reliably assess the risks from PGEs, traceable and thus comparable data on the release rates of PGE from automotive catalysers are needed. As no Certified Reference Materials (CRM) are available for such samples the development of analytical procedures enabling SI-traceable results will be challenging. Therefore reference procedures for Pd and Pt in automotive exhaust emissions based on isotope dilution mass spectrometry (IDMS) have been developed and applied to specifically sampled automotive exhaust emissions. Due to the commonly known advantages, IDMS often is applied for quantification PGEs, as is the case within this work. The main reasons here are the required accuracy and the low PGE mass fractions in the sample. In order to perform IDMS analysis the analyte element must be available in an isotopically enriched form as so-called spike material or solution thereof, which is mixed with the sample. Unfortunately, no certified PGE spike solutions are available yet. To fill this gap two single PGE spikes, one 106Pd and one 194Pt spike, have been produced and characterized. The selection of the isotopes, the production of the solutions and the ampoulation will be described in this

    Full Text Available The measurement uncertainty is useful to estimate the confidence of analytical results. Nowadays, a result without the uncertainty statement cannot be considered reliable, but the scientific literature still lacks examples of the estimate of the measurement uncertainty. This paper presents a practical and reliable description of the measurement uncertainty estimation of the analytical determination of ethyl carbamate in cachaça by GC-IDMS. The isotope dilution technique (ID associated with GC-MS was used to improve the accuracy. The uncertainty estimated corresponds to 10% of the mass fraction of ethyl carbamate (115 ± 11 ng/g, which is in agreement with ppb level.

    Full Text Available Abstract Background Despite the recent publication of results from two randomized clinical trials, prostate specific antigen (PSA screening for prostate cancer remains a controversial issue. There is lack of agreement across studies that PSA screening significantly reduces prostate cancer mortality. In spite of these facts, the widespread use of PSA testing in the United States leads to overdetection and overtreatment of clinically indolent prostate cancer, and its associated harms of incontinence and impotence. Discussion Given the inconclusive results from clinical trials and incongruent PSA screening guidelines, the decision to screen for prostate cancer with PSA testing is an uncertain one for patients and health care providers. Screening guidelines from some health organizations recommend an informed decision making (IDM or shared decision making (SDM approach for deciding on PSA screening. These approaches aim to empower patients to choose among the available options by making them active participants in the decision making process. By increasing involvement of patients in the clinical decision-making process, IDM/SDM places more of the responsibility for a complex decision on the patient. Research suggests, however, that patients are not well-informed of the harms and benefits associated with prostate cancer screening and are also subject to an assortment of biases, emotion, fears, and irrational thought that interferes with making an informed decision. In response, the IDM/SDM approaches can be augmented with strategies from the philosophy of libertarian paternalism (LP to improve decision making. LP uses the insights of behavioural economics to help people better make better choices. Some of the main strategies of LP applicable to PSA decision making are a default decision rule, framing of decision aids, and timing of the decision. In this paper, we propose that applying strategies from libertarian paternalism can help with PSA

  7. Cosmic acceleration without dark energy

    International Nuclear Information System (INIS)

    In this work, we investigate the global dynamics of the universe within the framework of the Interacting Dark Matter (IDM) scenario. Considering that the dark matter obeys the collisional Boltzmann equation, we can obtain analytical solutions of the global density evolution, which can accommodate an accelerated expansion, equivalent to either the quintessence or the standard Λ models. This is possible if there is a disequilibrium between the DM particle creation and annihilation processes with the former process dominating, which creates an effective source term with negative pressure. We also find realistic solutions in which the present time is located after the inflection point.

    Isotope dilution mass spectrometry (IDMS), an important metrological method, is widely used for absolute quantification of peptides and proteins. IDMS employs an isotope-labeled peptide or protein as an internal standard although the use of a protein provides improved accuracy. Generally, the isotope-labeled protein is obtained by stable isotope labeling by amino acids in cell culture (SILAC) technology. However, SILAC is expensive, laborious, and time-consuming. To overcome these drawbacks, a novel universal SI-traceable IDMS method for absolute quantification of proteins in a matrix is described with human transferrin (hTRF). The hTRF and a human serum sample were labeled with different tandem mass tags (TMTs). After mixing the TMT-labeled hTRF and serum sample together followed by digestion, the peptides were separated by nano-liquid chromatography and analyzed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Using the signature peptides, we calculated the ratios of reporter ions from the TMT-labeled peptides which, in turn, allowed determination of the mass fraction of hTRF. The recovery ranged from 97% to 105% with a CV of 3.9%. The LOD and LOQ were 1.71 × 10(-5) g/g and 5.69 × 10(-5) g/g of hTRF in human serum, respectively, and the relative expanded uncertainty was 4.7% with a mass fraction of 2.08 mg/g. For comparison, an enzyme-linked immunosorbent assay (ELISA) method for hTRF yielded a mass fraction of 2.03 mg/g. This method provides a starting point for establishing IDMS technology to accurately determine the mass fractions of protein biomarkers in a matrix with traceability to SI units. This technology should support the development of a metrological method useful for quantification of a wide variety of proteins. PMID:26942737

    The aim of the study was to determine the prevalence of orthorexia nervosa among the performance artists in the State Opera and Ballet and in the Bilkent University Symphony Orchestra. The study population consisted of 39 men and 55 women for a total of 94 artists with mean age of 33 years. The ORTO-15 test was used to determine the prevalence of orthorexia nervosa. Those subjects who scored below 40 in the ORTO-15 test were classified as having orthorexia nervosa. Mean score of the participants in the ORTO-15 test was 37.9+/-4.46. A total of 56.4% of the artists involved in the research scored below 40 in the ORTO-15 test. While the highest prevalence of orthorexia nervosa was recorded among opera singers (81.8%), it was 32.1% among ballet dancers and 36.4% among symphony orchestra musicians. The differences between the three groups were statistically significant. No difference was noted between mean ORTO-15 score by baseline characteristics as gender, age, educational level, work experience, body mass index, smoking and alcohol consumption. The research group have a higher socio-economic and education level than the majority of the general public in Turkey. Additionally, being an artist in Turkey means being a role model for the general public both in terms one's physical appearance and lifestyle. These may be the reason why artists are more sensitive to this issue.

    Results of physiological responses to music are inconclusive considering results of several studies, probably due to the insufficient control of the musical stimuli. The present study aimed to examine the effects of music type and preference on subjective and physiological responses using controlled stimuli by subjects' evaluations for music activity and preference. Subjects were 47 undergraduate students selected from a pool of 145 undergraduates. Results of evaluations of music activity and music preference for musical stimuli in preliminary research determined participation in the study. The music used in this study included the 4th movement of Tchaikovsky's Symphony No. 4 as an excitative piece and the 3rd movement of Mahler's Symphony No. 6 as a sedative one. The excitative music aroused feelings of vigor and tension more than did the sedative one, while sedative music eased tension. Favorite music, regardless of music type, lowered subjective tension. Physiological responses (heart rate, respiration, and blood pressure) were greater during excitative music than during sedative music. Music preference did not, however, affect physiological responses. These results indicate that the dominant factor affecting emotional response was music type but not preference. PMID:10519843

  18. Altered but Not Silenced: How Shostakovich Retained His Voice as an Artist despite the Demands of a Dictator

    Hope R. Strayer

    2013-12-01

    Full Text Available Can music that is regulated and restrained by a dictator still be inspired? This question reveals ideology concerning how music should be created and valued. Does outside control restrict artistic integrity and autonomy? Not all composers have been free to write whatever their soul demands. People in authority have held power and control over artistic processes. Dmitri Shostakovich was a Russian composer whose work was subjected to the tastes of a tyrannical ruler and Communist party. Though Shostakovich did not compose in an environment that fostered musical exploration, his work should not be mourned but celebrated. Shostakovich was not a victim, but a victor of his music by the way he composed in the midst of the threat of denouncement. Though Shostakovich wrote music to follow the demands of others, the music was still his by the very fact that he created it; he brought it into existence and highlighted it with nuances of his being and personality as he produced each work. This research examines three critical pieces of Shostakovich’s canon to ascertain whether controlled art subjected to the whims, preferences, and objectives of others can still be inspired. Though a composer might be told what to say, it is he who chooses how to word a phrase. Shostakovich’s output, particularly the first symphony, his opera Lady Macbeth of the Mtsensk District, and fifth symphony exemplify that restrained and restricted music does not necessitate a sacrifice in artistic integrity; it can be inspired, celebrated, and worthy of study.

    In this issue of Blood, Wilson et al generate and analyze a treasure trove of epigenetic data, such as transcription factor occupancy, histone modifications, and chromatin interaction frequencies, genome-wide (ie, epigenomic data), in a cell line model of hematopoietic stem/progenitor cells (HSPCs). To appreciate the importance of these data, consider an analogy of gene expression being a song or symphony (transcripts) played by musicians (transcription factors and transcriptional machinery) reading the score encoded in the genome sequence. Previous studies revealed the positions of a few transcription factors across the genome, so we only knew about, for example, the violinists and oboists. No wonder we did not understand how the music was being generated (how expression was regulated). By mapping the sites of occupancy of many more transcription factors (now a total of 29), as well as positions of 4 histone modifications and DNase hypersensitive sites, Wilson et al reveal many more of the players and their partners. Furthermore, their data on 3-dimensional interaction frequencies of chromatin show how groups of musicians (protein complexes) come together in an orchestra to read the score and perform a symphony.

    High-speed liquid jets have been applied to many fields of engineering, science and medicine. It is therefore of benefit to all these areas to investigate their characteristics by modern and inexpensive methods using a computational fluid dynamics (CFD) technique. Previously, high-speed liquid jets have been studied experimentally using a momentum exchange method, called the "impact driven method (IDM)", by which the impact of a high-velocity projectile on the liquid package contained in the nozzle cavity produced the jet. The shock pulse reflections in the cavity caused by the impact then drove a multiple pulsed jet from the nozzle exit. In this study, a two-fluid simulation consisting of liquid and air can be successfully calculated by using a two-phase flow mixture model and a moving mesh for the projectile motion. The CFD results show good agreement to the results of previous experimental studies, both quantitatively and qualitatively. For the first time, the wave propagation within the liquid in the nozzle has been captured and analyzed, thereby demonstrating the dynamic characteristics of multiple pulsed high-speed liquid jets initiated by the IDM. This provides a breakthrough in the simulation of the supersonic injection of a liquid into air by using a well-known and user-friendly CFD software. It is useful fundamental knowledge for future studies of high-speed injection with applications in all its related fields.

  2. The intelligent deep mine

    The intended 'Intelligent Deep Mine'' (IDM) initiative will cope with the challenges the mining industry is currently facing. The main focus will be on technological issues. An increasing share of the total mining production will be by underground mining. The mineral deposits will be found in gradually greater depths, including all problems associated with it. It involves an increase in overburden pressure with subsequent rock stability problems and risks of structural collapse. There is a need for new and safe technologies for deep underground mining. This need targets at nearly all parts of a modern mine, the infrastructure including the communication network, logistics and transport and will reach up to mine preparation work and the winning operation itself including maintenance. Additionally, the concept of near-to-face preparation will be considered in order to step into an ''Invisible Mine'' approach. The IDM project marks the start of a series of development activities aiming to realise the concept of an invisible, zero-impact mine. The extractive sector, still seen as being old-fashioned and highly environment polluting, will join forces to revise this image showing that minerals extraction and processing can be done in a highly innovative manner with low impact underground and zero impact above ground.

  3. A mediator embedded micro-immunosensing unit for electrochemical detection on viruses within physiological saline media

    International Nuclear Information System (INIS)

    To provide a time- and cost-saving alternative to the conventional methods for virus detection in biological media, this work presents an electrochemical micro-immunosensor based on the nickel hexacyanoferrate (NiHCF) redox mediator film coating the interdigitated microelectrodes (IDMEs). By chelation binding with no additional cross-linker, the 6xHis-tagged antibodies were immobilized on a NiHCF film. Secondly, an immunoassay response was enhanced by employing microbeads coated with 6xHis antibody. The electrochemical properties and the stability of the NiHCF film modified IDMEs were evaluated by cyclic voltammetry. The bead-induced impedance variations at the electrode film/electrolyte interface were characterized by electrochemical impedance spectroscopy and verified using FEM simulation. Experiments of virus detection were conducted through targeting the antigens of the vital infectious salmon viruses, such as infectious salmon anaemia virus, infectious pancreatic necrosis virus and salmonid alphavirus subtype 3. The micro-immunosensor exhibited detection limits as low as 10 pg ml−1 and detection sensitivities as high as 57.5 kΩ µM−1 within a physiological saline solution. Tests for multiple antigen–antibody interactions showed good detection specificity, as confirmed by ELISA. By incorporating the microfluidic network, electrochemical impedance micro-immunosensing units can be realized in a fully integrated platform for multiplex virus detection in tissue samples.

    For the past decade, operations and research projects that support a major portion of NASA's overall mission have experienced a dramatic increase in the volume of generated data and resultant information that is unparalleled in the history of the agency. The effect of such an increase is that most of the science and engineering disciplines are undergoing an information glut, which has occurred, not only because of the amount, but also because of the type of data being collected. This information glut is growing exponentially and is expected to grow for the foreseeable future. Consequently, it is becoming physically and intellectually impossible to identify, access, modify, and analyze the most suitable information. Thus, the dilemma arises that the amount and complexity of information has exceeded and will continue to exceed, using present information systems, the ability of all the scientists and engineers to understand and take advantage of this information. As a result of this information problem, NASA has initiated the Intelligent Data Management (IDM) project to design and develop Advanced Information Management (IDM) project to design and develop Advanced Information Management Systems (AIMS). The first effort of the Project was the prototyping of an Intelligent User Interface (IUI) to an operational scientific database using expert systems, natural language processing, and graphics technologies. An overview of the IUI formulation and development for the second phase is presented.

The animals were evaluated over a 60-day period, day 0 being defined as the day on which the streptozotocin-injected animals presented glycemia > 250 mg/dL. The SOD was administered for the last 7 days of that period. At the end of the study period, samples of lung tissue were collected for histopathological analysis, evaluation of tissue oxidative stress, and assessment of DNA damage. RESULTS: There were no significant differences among the groups regarding DNA damage. In the IDM-only group, there was a significant increase in the extracellular matrix and significantly greater hyperplasia of the capillary endothelium than in the SOD-only and control groups. In addition, there were significant changes in type II pneumocytes and macrophages, suggesting an inflammatory process, in the IDM-only group. However, in the IDM+SOD group, there was a reduction in the extracellular matrix, as well as normalization of the capillary endothelium and of the type II pneumocytes. CONCLUSIONS: Exogenous SOD can reverse changes in the lungs of animals with induced DM.

    Background Serum creatinine (Scr) measurement plays a key role in glomerular filtration rate estimation (eGFR),chronic kidney disease (CKD) diagnosis as well as CKD treatment. However, the test results of Scr from different laboratories vary significantly. In order to get comparable results, the European in vitro diagnostic (IVD) directive requires traceability to reference methods and materials. The purpose of this study was to verify the effect of traceability implementation by investigating the trueness of creatinine measurement on nine homogenous systems in Beijing. Methods Commutable frozen human serum reference material, National Institute of Standards & Technology (NIST) Standard Reference Material (SRM) 967, was used to verify the trueness of Scr measurement results from nine homogeneous analytical systems of seven companies which are the most widely used systems in Beijing's third-grade hospitals. The methods referred to the Jaffe's and Enzymatic methods. Results from nine routine measurement systems were assessed using two criteria: biological variability and Clinical Laboratory Improvement Amendments' 88 (CLIA' 88).We simulated a series of broken lines representing the limits of SD and bias that would produce a relative increase (or decrease) of 10% and 20% in the measurement error when estimating GFR (MEeGFR) using the isotope dilution mass spectrometry (IDMS)-traceable Modification of Diet in Renal Disease (MDRD) Study equation. Results of the College of American Pathologists (CAP) 2008-B LN24 Survey were compared with our investigation results. Results Compared with the total error criteria of biological variability, Ortho (traceable to IDMS) met the minimum acceptable criteria; Roche (Jaffe), Roche (Enzymatic), Shino and Daiichi met the desirable criteria at level Ⅰ. At level Ⅱ, Ortho (traceable to gas chromatography/isotope dilution mass spectrometry, GC/IDMS), Dade Behring and Beckman (traceable to rate Jaffe) met the minimum acceptable

    Objective To evaluate the application of 6 creatinine-based equations of estimated glomerular filtration rate (eGFR)by enzymatic method and kinetic alkaline picric acid rate method in healthy population.Methods Serum creatinine was measured by enzymatic method and kinetic alkaline picric acid rate method in 694 healthy subjects.The eGFR values were calculated and compared by 6 equations [Cockcroft-Gault (C-G)equation,simplified modification of diet in renal disease (MDRD)equation,MDRD-Chinese equation,isotopic dilution mass spectrometry (IDMS)-MDRD equation,chronic kidney disease epidemiology collaboration (CKD-EPI)equation and CKD-EPI for Asian (EPI-Asian) equation].Results Serum creatinine results were(65.8 ± 13.3)μmol/L[(36-117)μmol/L)for enzymatic method, (83.0 ±12.7)μmol/L[(57-131)μmol/L]for kinetic alkaline picric acid rate method.According to eGFR reference intervals:85-125mL/min for males and 75-115mL/min for females,if using enzymatic method to detect creatinine,the applicability in healthy subjects of 6 equations were CKD-EPI equation (72.3%)>IDMS-MDRD equation(69.9%)>simplified MDRD equation(61.3%)>EPI-Asian equation (60.7%)>C-G equation(54.8%)>MDRD-Chinese people equation (27.3%)(PEPI-Asian equation (70.1%)>CKD-EPI equation (63.8%)>simplified MDRD equation(59.1%)>C-G equation(52.4%)>IDMS-MDRD equation(40.7%)(P<0.05),and MDRD-Chinese people equation showed the smallest difference between males and females (only 1%).Conclusions There are significant differences among 6 equations.To evaluate eGFR in healthy subjects in North China,CKD-EPI equation and IDMS-MDRD equation are more applicable if using enzymatic mehod traced to IDMS to detect serum creatnine,while MDRD-Chinese people equation is more applicable if using kinetic alkaline picric acid rate method to detect serum creatnine.%目的:评价基于酶法和苦味酸速率法的血清肌酐的6种估算的肾小球滤过率(eGFR)公式在表观健康人群中的适用性。方法从

  8. Pharmaceuticals, hormones and bisphenol A in untreated source and finished drinking water in Ontario, Canada - Occurrence and treatment efficiency

    International Nuclear Information System (INIS)

    The Ontario Ministry of the Environment (MOE) conducted a survey in 2006 on emerging organic contaminants (EOCs) which included pharmaceuticals, hormones and bisphenol A (BPA). The survey collected 258 samples over a 16 month period from selected source waters and 17 drinking water systems (DWSs), and analyzed them for 48 EOCs using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and isotope dilution mass spectrometry (IDMS) for the highest precision and accuracy of analytical data possible. 27 of the 48 target EOCs were detected in source water, finished drinking water, or both. DWSs using river and lake source water accounted for > 90% detections. Of the 27 EOCs found, we also reported the first detection of two antibiotics roxithromycin and enrofloxacin in environmental samples. The most frequently detected compounds (≥ 10%) in finished drinking water were carbamazepine (CBZ), gemfibrozil (GFB), ibuprofen (IBU), and BPA; with their concentrations accurately determined by using IDMS and calculated to be 4 to 10 times lower than those measured in the source water. Comparison of plant specific data allowed us to determine removal efficiency (RE) of these four most frequently detected compounds in Ontario DWSs. The RE of CBZ was determined to be from 71 to 93% for DWSs using granulated activated carbon (GAC); and was 75% for DWSs using GAC followed by ultraviolet irradiation (UV). The observed RE of GFB was between 44 and 55% in DWSs using GAC and increased to 82% when GAC was followed by UV. The use of GAC or GAC followed by UV provided an RE improvement of BPA from 80 to 99%. These detected concentration levels are well below the predicted no effect concentration or total allowable concentration reported in the literature. Additional targeted, site specific comparative research is required to fully assess the effectiveness of Ontario DWSs to remove particular compounds of concern. - Research Highlights: → Occurrence and typical range of 45 selected

    In Online Social Networks(OSNs) multiple contagions not only propagate through the network but also interact with each other at the same time. In order to understand the diffusion process of contagions it is necessary to study how different contagions interact. Most of prior work considered individual contagions as independent and thus spreading in isolation. In this paper, an analo-gy is made between OSNs and biology systems. The interaction among contagions could be regarded as the competing among spe-cies. An Interaction Diffusion Model(IDM) is proposed, which is based on the classic reaction diffusion equation in dynamic biology systems to describe and predict the interactions among multiple contagions. Two real datasets collected from Github are used to tes-tify the predicting performance of the IDM model. Experimental results show that IDM model outperforms the compared models at predicting accuracy.%在社交网络(OSNs)中,各个信息不仅独立通过网络传播,而是在传播的过程中彼此进行交互。为了理解社交网络中相关联信息的扩散过程,需要研究不同的信息在传播过程中是如何交互的。目前,大部分的研究都认为不同信息的传播过程之间相互独立。将社交网络和具有食物链的生态系统进行了类比,信息之间的相互作用可以被视为物种之间的竞争,基于经典的动态生态系统的反应扩散模型,建立起了IDM模型。从Github上收集了两个真实的数据集,并通过实验结果证明了:相对于Lotka-Volterra模型模型,IDM模型具有更优秀的预测性能。

    To standardize C-reactive protein (CRP) assays, the National Metrology Institute of Japan (NMIJ) has developed a C-reactive protein solution certified reference material, CRM 6201-b, which is intended for use as a primary reference material to enable the SI-traceable measurement of CRP. This study describes the development process of CRM 6201-b. As a candidate material of the CRM, recombinant human CRP solution was selected because of its higher purity and homogeneity than the purified material from human serum. Gel filtration chromatography was used to examine the homogeneity and stability of the present CRM. The total protein concentration of CRP in the present CRM was determined by amino acid analysis coupled to isotope-dilution mass spectrometry (IDMS-AAA). To improve the accuracy of IDMS-AAA, we optimized the hydrolysis process by examining the effect of parameters such as the volume of protein samples taken for hydrolysis, the procedure of sample preparation prior to the hydrolysis, hydrolysis temperature, and hydrolysis time. Under optimized conditions, we conducted two independent approaches in which the following independent hydrolysis and liquid chromatography-isotope dilution mass spectrometry (LC-IDMS) were combined: one was vapor-phase acid hydrolysis (130 °C, 24 h) and hydrophilic interaction liquid chromatography-mass spectrometry (HILIC-MS) method, and the other was microwave-assisted liquid-phase acid hydrolysis (150 °C, 3 h) and pre-column derivatization liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The quantitative values of the two different amino acid analyses were in agreement within their uncertainties. The certified value was the weighted mean of the results of the two methods. Uncertainties from the value-assignment method, between-method variance, homogeneity, long-term stability, and short-term stability were taken into account in evaluating the uncertainty for a certified value. The certified value and the

    The objective of this study was to determine what financial return, if any, DOE would realize if they invest solely in removal of the asbestos from these three Hanford steam plants and the associated large bore distribution piping at the site. Once the asbestos was removed the strategy was to bring in companies that specialize in salvage and material re-use and have them remove, at no cost to DOE, the plants and the associated large bore piping. The salvage companies we contacted had said that if they didn't have to remove asbestos, they may be able to realize enough value from these plants to offset their demolition and/or dismantling cost. The results were not what we expected but they do offer DOE some favorable financial alternatives to their present approach. The study concluded that there was very little salvage and/or re-use value remaining in the steam plant material that could be used to offset the demolition and/or dismantling cost. The notable exception to this is the removal of the 24 inch steam piping that runs from 200E to 200W areas (see IDM executive summary under Dismantling cost). It is estimated that the re-use value of the 24-inch piping would more than pay for the dismantling cost of this piping. On a more favorable note, it does appear as though the cost of conventional demolition can be reduced by a factor of 3 to 5 if the asbestos is removed first and the demolition is performed using competitive and commercial practices. Both estimates in this study are similar except that IDM did not include floor slab removal nor remove the same quantity of piping. This is why we are using a range of 3 to 5 as a reduction factor. The IDM estimate (using union labor) for demolition after removal of asbestos was approximately $1.5M versus $10.0M for accomplishing the work using Hanford practices and rates.

Compared with the IFM, the IDM can obtain rich dynamic information including chaos, phase locking, etc., without using varying threshold modulation. The corresponding relation between output symbolic sequences and parameters (i.e., frequency, amplitude, resistance and capacity) of the IDM is established by using symbolic dynamics. Moreover, a method of obtaining symbolic sequence as well as an ordering rule is presented. Simulation and circuit experiment validate the correctness of the method and the rule. The results of circuit experiment show that the frequency resolution can reach up to 0.05 Hz in some frequency ranges and the amplitude resolution can reach up to 1 µA.

    The symphony of the human genome concludes with a long Gregorian chant of TTAGGG repeats. This monotonous coda represents one of the most complex problems in chromosome biology: the question of how cells distinguish their natural chromosome ends from double-strand breaks elsewhere in the genome. McClintock's classic finding of chromosome breakage-fusion-bridge cycles, first reported by her at one of the early Cold Spring Harbor Laboratory Symposia (the ninth), served as a prelude to this question. The 75th Cold Spring Harbor Laboratory Symposium marks the completion of a series of mouse gene deletion experiments that revealed DNA-damage-response pathways that threaten chromosome ends and how the components of the telomeric shelterin complex prevent activation of these pathways.

    Over centuries and millennia, our ancestors worldwide found the most appropriate materials for increasingly complex acoustical applications. In the temperate climate of Europe, where the instruments of the Western symphony orchestra were developed and perfected, instrument makers still primarily take advantage of the unique property combination and the aesthetic appeal of wood. In all other continents, one material dominates and is frequently chosen for the manufacture of wind, string, and percussion instruments: the grass bamboo. Here, we review from a materials science perspective bamboo's and wood's unique and highly optimized structure and properties. Using material property charts plotting acoustic properties such as the speed of sound, the characteristic impedance, the sound radiation coefficient, and the loss coefficient against one another, we analyze and explain why bamboo and specific wood species are ideally suited for the manufacture of xylophone bars and chimes, flutes and organs, violins and zithers, violin bows, and even strings.

  1. Religion and Cultural Identity in Shakespeare’s Romeo and Juliet and the Musical Works it Inspired

    Directory of Open Access Journals (Sweden)

    Bottez Alina

    2016-08-01

    Full Text Available Protean Shakespeare thrives not only in the theatre, but also through what Bolter and Grusin call remediation. This article analyses the religious stances in the play and then shows how opera, symphony and musical have been adapting the veteran Elizabethan drama since the 18th century. Its main approach is comparative and relies on the history of mentalities. Adaptation is dictated by cultural context, the conventions of the lyrical theatre, social and political factors, and reception. The confusing religious configuration of Shakespeare’s England is reinterpreted kaleidoscopically. The article demonstrates, for instance, that Berlioz and Gounod reread it according to staunch Catholicism in 19th century France, while Bernstein’s West Side Story moves the action to New York in the mid- 50’s, the Capulets and Montagues are replaced with rival Polish and Puerto Rican gangs and religion with cultural identity.

  3. From modernism to socialist realism in four years: Myaskovsky and Asafyev

    Directory of Open Access Journals (Sweden)

    Frolova-Walker Marina

    2003-01-01

    Full Text Available Two outstanding personalities of the Soviet musical life in the 1920's, the composer Nikolay Myaskovsky and the musicologist Boris Asafyev, both exponents of modernism, made volte-faces towards traditionalism at the beginning of the next decade. Myaskovsky's Symphony no. 12 (1931 and Asafyev's ballet The Flames of Paris (1932 became models for Socialist Realism in music. The letters exchanged between the two men testify to the formers uneasiness at the great success of those of his works he considered not valuable enough, whereas the latter was quite satisfied with his new career as composer. The examples of Myaskovsky and Asafyev show that early Soviet modernists made their move away from avant-garde creativity well before they faced any real danger from the bureaucracy.

    2010-01-01

    The symphony of the human genome concludes with a long Gregorian chant of TTAGGG repeats. This monotonous coda represents one of the most complex problems in chromosome biology: the question of how cells distinguish their natural chromosome ends from double-strand breaks elsewhere in the genome. McClintock's classic finding of chromosome breakage-fusion-bridge cycles, first reported by her at one of the early Cold Spring Harbor Laboratory Symposia (the ninth), served as a prelude to this question. The 75th Cold Spring Harbor Laboratory Symposium marks the completion of a series of mouse gene deletion experiments that revealed DNA-damage-response pathways that threaten chromosome ends and how the components of the telomeric shelterin complex prevent activation of these pathways.

    "I am three times without a country; a Bohemian among Austrians, an Austrian among Germans, and a Jew among all the peoples of the world". This famous quotation is typical of Gustav Mahler (1860-1911) and reflects his difficult and stormy life. His rheumatic mitral valve disease, diagnosed in 1907, was probably asymptomatic until recurrent throat infections put an end to his life. At the time of his death Mahler was at the peak of his career as a conductor, with 90 concerts scheduled for the 1910-11 season. He had completed his 9th and begun his 10th symphony, but would his real task as a composer have survived the serious domestic crisis and threatened his artistic life? "My time will come" said Mahler, and by this he meant the acknowledgement of his music. But this took a long time. Today Mahler's music is played all over the world. Without doubt he is "eternal among the great". PMID:8278964

    Can "all" students learn "real" physics? Physics First and Physics for All have become a success story for thousands of students in urban, suburban, and rural districts. At the same time, the International Physics Olympiad and other competitions have raised the expectation of what the most motivated students can achieve. Many physics educators are exploring ways to set higher goals for our most gifted students while also providing physics instruction to students previously excluded from our physics classes. Great novels and symphonies are accessible to people of different backgrounds and levels of expertise. We should develop teaching strategies that enable us to share an understanding of physics with all students because everyone deserves an opportunity to reflect on the wondrous workings of our universe.

  7. Igor Stravinsky: The Poetics and Politics of Music

    Directory of Open Access Journals (Sweden)

    Howard Gardner

    2013-12-01

    Full Text Available The most famous sentence in Igor Stravinsky’s autobiography reads: “Music is by its very nature powerless to express anything at all.” When it appeared, this sentence surprised his audience. After all, Stravinsky had composed some of the most expressive music of the twentieth century, from the lyrical Petrouchka to the dramatic Le sacre du printemps (The Rite of Spring to the elegaic Symphony of Psalms. But ever the polemicist, Stravinsky was in actuality blasting those whom he regarded as his aesthetic opponents, such as the followers of Richard Wagner; such “impurists” were always marshaling music in the service of extramusical ends, from national solidarity to religious freedom. Seeking to repair a perceived imbalance, Stravinsky portrayed the musician as a craftsman whose materials of pitch and rhythm in themselves harbor no more expression than the carpenter’s beams or the jeweler’s stone.

    The Jeffreys Symposium at the International Union of Geodesy and Geophysics meeting in Vienna (August 11-24 presented a wonderful symphony of 19 maestros performing throughout the whole spectrum of Earth and planetary sciences. The symposium was well-received by the audience and ended with a standing ovation to Lady Jeffreys, who listened to all presentations with keen interest.B. Bolt opened the symposium with “Jeffreys and the Earth,” a paper that succinctly reviewed Jeffreys' overwhelming work, based largely on his mastery of simple representations to produce mathematical models of complicated structures and processes. A model simple enough for the application of principles of mathematical physics, and yet capable of capturing the essence of the subject phenomenon, is essential to successful geophysics.

  10. Beethoven's deafness, the defiance of a genius

    Directory of Open Access Journals (Sweden)

    Bento, Ricardo Ferreira

    2009-09-01

    Full Text Available Introduction: Ludwig van Beethoven, one of the greatest composers in History, was tormented for his whole life by a progressive deafness without definitive diagnosis. Many authors published studies about the etiologic possibilities of the deafness of the music genius with different explanations about his auditory loss. In this work, the author discusses the implications of Beethoven's progressive deafness to the creation of his word, as well as etiologic assumptions of his disease. Would Beethoven have had the same ingeniousness he showed in his symphonies if he did not have hypacusis and tinnitus? What is the influence of his deafness on his work and life? Could he have had a more precise diagnosis and specially a treatment nowadays? Would we have the brilliant composer if he had deafness today? We surely could not have!

    Full Text Available This article reports on a collaborative short-term project between the Melbourne Symphony Orchestra and the Music Therapy team at The Royal Children's Hospital, Melbourne to provide live music on the Neonatal ward of the hospital. The focus was for the music therapists and musicians to develop their understanding and capability to provide live music in an environment for medically fragile patients. To extend the benefit of this experience, guidelines for future musicians were also produced. The guidelines were created through a process of narratives and discussions which were transcribed, and subjected to a thematic analysis. Mid and final review meetings for the whole team encouraged discussion about the emerging themes and final collation of guidelines. The guidelines were intended to offer guidance for new Arts in Health programs or for solo musicians volunteering in a hospital without such a program.

  18. Optimization of Orchestral Layouts Based on Instrument Directivity Patterns

    Science.gov (United States)

    Stroud, Nathan Paul

    The experience of hearing an exceptional symphony orchestra perform in an excel- lent concert hall can be profound and moving, causing a level of excitement not often reached for listeners. Romantic period style orchestral music, recognized for validating the use of intense emotion for aesthetic pleasure, was the last significant development in the history of the orchestra. In an age where orchestral popularity is waning, the possibil- ity of evolving the orchestral sound in our modern era exists through the combination of our current understanding of instrument directivity patterns and their interaction with architectural acoustics. With the aid of wave field synthesis (WFS), newly proposed variations on orchestral layouts are tested virtually using a 64-channel WFS array. Each layout is objectively and subjectively compared for determination of which layout could optimize the sound of the orchestra and revitalize the excitement of the performance.

    Pandya, Alex; Chandra, Mani; Gammie, Charles F

    2016-01-01

    Synchrotron emission and absorption determine the observational appearance of many astronomical systems. In this paper, we describe a numerical scheme for calculating synchrotron emissivities and absorptivities in all four Stokes parameters for arbitrary gyrotropic electron distribution functions, building on earlier work by Leung, Gammie, and Noble. We use this technique to evaluate the emissivities and the absorptivities for a thermal (Maxwell-J\\"uttner), isotropic power-law, and isotropic kappa distribution function. The latter contains a power-law tail at high particle energies that smoothly merges with a thermal core at low energies, as is characteristic of observed particle spectra in collisionless plasmas. We provide fitting formulae and error bounds on the fitting formulae for use in codes that solve the radiative transfer equation. The numerical method and the fitting formulae are implemented in a compact C library called ${\\tt symphony}$. We find that: the kappa distribution has a source function th...

    Room acoustics computer modeling is a tool for generating impulse responses and auralizations from modeled spaces. The auralizations are commonly made from a single-channel anechoic recording of solo instruments. For this investigation, auralizations of an entire orchestra were created using...... a multi-channel multi-source auralization technique, involving individual five-channel anechoic recordings of each instrumental part of two symphonies. In the first study, these auralizations were subjectively compared to orchestra auralizations made using (a) a single omni-directional source, (b......, subjects could only discern differences between the orchestra configurations with the five-channel multi-source auralizations. Overall, the multi-source auralization technique was found to be an effective method for creating realistic orchestra auralizations, but using multichannel anechoic recordings...

    We report a case of a 52-year-old woman with a palpable recurrent metastasis of a neuroendocrine carcinoma to the upper outer quadrant of the right breast. For the treatment of this lesion, MR-guided laser-induced thermotherapy was performed with a cooled power laser system (Nd:YAG-Laser). An open 0.2-T MR unit was used for the monitoring of the laser energy delivery to the breast; thus, a thermosensitive fast low-angle shot 2D sequence for MR thermometry was used, so the ablation of the tumor and the increase of laser-induced necrosis could be interactively visualized with the repetitive use of this sequence. The postinterventional MR control exams 1 day and 4 months after laser-induced thermotherapy at the 1.5-T MR unit (Magnetom Symphony Quantum, Siemens, Erlangen, Germany) verified the complete ablation of the tumor without any signs of residual or relapsing tumor.

    2009-07-01

    Full Text Available Software rearchitecting is the process of obtaining a documented architecture for an existing system. There are many software rearchitecting frameworks which are based upon different concepts and context-related issues for a specific application or programming language, such as Rigi, Ciao, SPOOL, and Symphony, and Software Rearchitecting Action Framework (SRAF. Most of the frameworks focus on the reverse engineering process of source code. They neglect the role of stakeholders in enhancing and developing their systems. This paper presents a systematic analysis and comparative study for rearchitecting frameworks using generic architecture characteristics or elements. Based on the major requirements that should be available in the rearchitecting frameworks, the comparative study proceeds. An efficient model is proposed based on the trends that resulted from the comparative analysis. It considers the evaluation criteria of the compared frameworks. Conclusions and remarks are highlighted.

    2012-01-01

    This paper describes a new approach for the determination of amitriptyline in wastewater by ionic liquid based immersed droplet microextraction (IL-IDME) prior to highperformance liquid chromatography with ultraviolet detection. 1-Hexyl-3-methylimidazolium hexafluorophosphate ([C6MIM][PF6]) was used as an ionic liquid. Various factors that affect extraction, such as volume of ionic liquid, stirring rate, extraction time, pH of the aqueous solution and salting effect, were optimized. The optimal conditions were as follows: microextraction time, 10 min; stirring rate, 720 rpm; pH, 11; ionic drop volume, 100 uL; and no sodium chloride addition. In quantitative experiments the method showed linearity in a range from 0.01 to 10 ug/mL, a limit of detection of 0.004 ug/mL and an excellent pre-concentration factor (PF) of 1100. Finally, the method was successfully applied to the determination of amitriptyline in the hospital wastewater samples.

    2016-01-01

    The NGSIM trajectory data are used to calibrate two car-following models - the IDM and the FVDM. We used the I80 dataset which has already been reconstructed to eliminate outliers, unphysical data, and internal and platoon inconsistencies contained in the original data.We extract from the data leader-follower pairs and platoons of up to five consecutive vehicles thereby eliminating all trajectories that are too short or contain lane changes. Four error measures based on speed and gap deviations are considered. Furthermore, we apply three calibration methods: local or direct calibration, global calibration, and platoon calibration. The last approach means that a platoon of several vehicles following a data-driven leader is simulated and compared to the observed dynamics.

    This paper discusses three kinds of IDM car-following models that consider both the multi-anticipative behaviors and the reaction delays of drivers. Here, the multi-anticipation comes from two ways: (1) the driver is capable of evaluating the dynamics of several preceding vehicles, and (2) the autonomous vehicles can obtain the velocity and distance information of several preceding vehicles via inter-vehicle communications. In this paper, we study the stability of homogeneous traffic flow. The linear stability analysis indicates that the stable region will generally be enlarged by the multi-anticipative behaviors and reduced by the reaction delays. The temporal amplification and the spatial divergence of velocities for local perturbation are also studied, where the results further prove this conclusion. Simulation results also show that the multi-anticipative behaviors near the bottleneck will lead to a quicker backwards propagation of oscillations.

Integrated disease management (IDM of mild to moderate COPD patients has been demonstrated to improve exercise capacity and health status after one year, but long-term results are currently lacking in primary care.Methods: Long-term data from the Bocholtz study, a controlled clinical trial comparing the effects of IDM versus usual care on health status in 106 primary care COPD patients during 24 months of follow-up, were analyzed using the Clinical COPD Questionnaire (CCQ. In addition, the Kroonluchter IDM implementation program has treated 216 primary care patients with mild to moderate COPD since 2006. Longitudinal six-minute walking distance (6MWD results for patients reaching 24 months of follow-up were analyzed using paired-sample t-tests. In prespecified subgroup analyses, the differential effects of baseline CCQ score, Medical Research Council (MRC dyspnea score, and 6MWD were investigated.Results: In the Bocholtz study, subjects were of mean age 64 years, with an average postbronchodilator forced expiratory volume in one second (FEV1 of 63% predicted and an FEV1/forced vital capacity (FVC ratio of 0.56. No significant differences existed between groups at baseline. CCQ improved significantly and in a clinically relevant manner by 0.4 points over 24 months; effect sizes were doubled in patients with CCQ > 1 at baseline and tripled in patients with MRC dyspnea score

    2008-01-01

    Vehicle-to-vehicle communications can be used effectively for intelligent transport systems (ITS) and location-aware services. The ability to disseminate information in an ad-hoc fashion allows pertinent information to propagate faster through the network. In the realm of ITS, the ability to spread warning information faster and further is of great advantage to the receivers of this information. In this paper we propose and present a message-dissemination procedure that uses vehicular wireless protocols for influencing traffic flow, reducing congestion in road networks. The computational experiments presented in this paper show how an intelligent driver model (IDM) and car-following model can be adapted to 'react' to the reception of information. This model also presents the advantages of coupling together traffic modelling tools and network simulation tools.

    Full Text Available Several earthquakes with strong magnitude occurred globally at various locations, especially the unforgettable tsunami disaster caused by the earthquake in Indonesia and Japan. If the characteristics of structures can be well understood to implement new technology, the damages caused by most natural disasters can be significantly alleviated. In this research, dynamic digital image correlation method for using continuous parameter is applied for developing a low-cost digital image correlation coefficient method with advanced digital cameras and high-speed computers. The experimental study using cantilever test object with defect control confirms that the vibration mode calculated using this proposed method can highly express the defect locations. This proposed method combined with the sensitivity of Inter-Story Drift Mode Shape, IDMS, can also reveal the damage degree of damage structure. These test and analysis results indicate that this proposed method is high enough for applying to achieve the object of real-time online monitoring of structure.

    The introduction of inline coherent imaging technologies as a sensor for the laser materials processing is accompanied by the integration into several applications. One of these is the measurement of the depth of the vapor capillary for laser welding applications, now allowing to keep record of the welding depth with an accuracy of micrometers and a sub millisecond temporal resolution. The broader achievement is the closed-loop control of the welding depth that was not available in industrial environments till now due to the lack of an adequate sensor. Further use includes the acquisition of 3D images around the laser process itself, allowing for coaxial integration of pre- and post-process sensors. These applications are demonstrated by using the In-Process Depth Meter (IDM).

    2016-01-01

    We study an extension of the Standard Model (SM) in which two copies of the SM scalar $SU(2)$ doublet which do not acquire a Vacuum Expectation Value (VEV), and hence are \\textit{inert}, are added to the scalar sector. We allow for CP-violation in the \\textit{inert} sector, where the lightest \\textit{inert} state is protected from decaying to SM particles through the conservation of a $Z_2$ symmetry. The lightest neutral particle from the \\textit{inert} sector, which has a mixed CP-charge due to CP-violation, is hence a Dark Matter (DM) candidate. We discuss the new regions of DM relic density opened up by CP-violation, and compare our results to the CP-conserving limit and the Inert Doublet Model (IDM). We constrain the parameter space of the CP-violating model using recent results from the Large Hadron Collider (LHC) and DM direct and indirect detection experiments.

  20. Improvement of the interfacial Dzyaloshinskii-Moriya interaction by introducing a Ta buffer layer

    International Nuclear Information System (INIS)

    We report systematic measurements of the interfacial Dzyaloshinskii-Moriya interaction (iDMI) by employing Brillouin light scattering in Pt/Co/AlOx and Ta/Pt/Co/AlOx structures. By introducing a tantalum buffer layer, the saturation magnetization and the interfacial perpendicular magnetic anisotropy are significantly improved due to the better interface between heavy metal and ferromagnetic layer. From the frequency shift between Stokes- and anti-Stokes spin-waves, we successively obtain considerably larger iDM energy densities (Dmax = 1.65 ± 0.13 mJ/m2 at tCo = 1.35 nm) upon adding the Ta buffer layer, despite the nominally identical interface materials. Moreover, the energy density shows an inverse proportionality with the Co layer thickness, which is the critical clue that the observed iDMI is indeed originating from the interface between the Pt and Co layers

    The artificial sweeteners sucralose (SCL), acesulfame (ACS), saccharin (SAC), and cyclamate (CYC) have been detected in environmental waters in Europe and North America. Higher environmental levels are expected in view of the increasing consumption of these food additives. In this study, an isotope-dilution mass spectrometry (IDMS) LC-MS/MS method was developed and validated for quantifying the four artificial sweeteners in boreal lakes (n = 3) and rivers (n = 12). The highest concentrations of ACS, SAC, CYC and SCL were 9,600, 490, 210 and 1000 ng/L, respectively. ACS and SAC were detected in all studied samples, and CYC and SCL in 98% and 56% of the samples. Seasonal trends of ACS and SAC were observed in some rivers. ACS and SCL concentrations in rivers correlated linearly with population equivalents of the wastewater treatment plants in the catchment areas, whereas SAC and CYC concentrations depend more on the source.

  2. Errors of DWPF frit analysis: Final report

    International Nuclear Information System (INIS)

    Glass frit will be a major raw material for the operation of the Defense Waste Processing Facility. The frit will be controlled by certificate of conformance and a confirmatory analysis from a commercial analytical laboratory. The following effort provides additional quantitative information on the variability of frit chemical analyses at two commercial laboratories. Identical samples of IDMS Frit 202 were chemically analyzed at two commercial laboratories and at three different times over a period of four months. The SRL-ADS analyses, after correction with the reference standard and normalization, provided confirmatory information, but did not detect the low silica level in one of the frit samples. A methodology utilizing elliptical limits for confirming the certificate of conformance or confirmatory analysis was introduced and recommended for use when the analysis values are close but not within the specification limits. It was also suggested that the lithia specification limits might be reduced as long as CELS is used to confirm the analysis

    We investigate the phenomenology of the charged and neutral scalars in Inert Doublet Model (IDM) at future $e^+ e^-$ linear colliders with center of mass energies of 0.5 to 1 TeV and integrated luminosity of 500 $fb^{-1}$. The analysis covers two processes, i.e. $e^{+}e^{-} \\rightarrow H^{+}H^{-}$ and $e^{+}e^{-}\\rightarrow AH$, and consists of a phenomenological signal selection as well as dark matter mass measurement. Several benchmark points are studied with focus on $H^{\\pm} \\rightarrow W^{\\pm}H$ and $A \\rightarrow ZH$ decays. It is concluded that the signal should be well observable in different final states and by combining information from different channels the dark matter mass should also be measurable with a reasonable precision.

    2015-01-01

    Knowledge-Based Engineering (KBE) is introduced into the ship structural design in this paper. From the implementation of KBE, the design solutions for both Rules Design Method (RDM) and Interpolation Design Method (IDM) are generated. The corresponding Finite Element (FE) models are generated. Topological design of the longitudinal structures is studied where the Gaussian Process (GP) is employed to build the surrogate model for FE analysis. Multi-objective optimization methods inspired by Pareto Front are used to reduce the design tank weight and outer surface area simultaneously. Additionally, an enhanced Level Set Method (LSM) which employs implicit algorithm is applied to the topological design of typical bracket plate which is used extensively in ship structures. Two different sets of boundary conditions are considered. The proposed methods show satisfactory efficiency and accuracy.

    We are in the era of mobile computing with smart handheld devices and remote data storage "in the cloud," with devices that are almost always on and driven by needs of high data transmission rate, instant access/connection and long battery life. With all the ambitious requirements for better performance with lower power consumption, the SoC solution must also be cost-effective in order to capture the large, highly-competitive consumer mobile and wearable markets. The Fully-Depleted SOI device/circuit is a unique option that can satisfy all these requirements and has made tremendous progress in development for various applications and adoption by foundries, integrated device manufacturers (IDM), and fabless companies in the last 3 years.

    Bring telescope to where the people are! Music and Astronomy Under the Stars (MAUS) is a NASA-funded as astronomy outreach program at community parks and music festivals (1000 - 25,000 people/event). While there have been many astronomy outreach activities and telescope observations at sidewalks and parks, this program targets a different audience - music lovers who are attending concerts in community parks or festivals. These music lovers who may not have visited science museums, planetariums, or star parties are exposed to telescope observations and astronomy information with no additional travel costs. MAUS includes solar observing, telescope observations including a live imaging system, an astronomical video, astronomy banners/posters, and hands-on activities. MAUS increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. Since 2009 over 50,000 people have participated in these outreach activities including a significant number of families and young girls. In addition to concerts in local Long Island parks, there were MUAS events at Tanglewood (summer home of the Boston Symphony Orchestra), Jazz in Central Park, and Astronomy Night on the National Mall (co-sponsored by the White House Office of Science and Technology Policy). In 2011 MUAS will be expanded to include Ravinia (summer home of the Chicago Symphony Orchestra), the Newport Folk Festival, and the Bethel Woods Center for the Arts (site of the 1969 Woodstock festival). According to our survey results, music lovers became more informed about astronomy. Expanding Hofstra University's successful outreach programs, I propose the creation of a National Halloween Stars event targeting children and a National Super Bowl Star Party targeting girls, women, and the 2/3 of Americans who do not watch the Super Bowl. This can be combined with astronomers or amateur astronomers bringing telescopes to Super Bowl parties for football fans to stargaze during

  10. Poker Face of Inelastic Dark Matter: Prospects at Upcoming Direct Detection Experiments

    The XENON100 and CRESST experiments will directly test the inelastic dark matter explanation for DAMA's 8.9{sigma} anomaly. This article discusses how predictions for direct detection experiments depend on uncertainties in quenching factor measurements, the dark matter interaction with the Standard Model and the halo velocity distribution. When these uncertainties are accounted for, an order of magnitude variation is found in the number of expected events at CRESST and XENON100. The process of testing the DAMA anomaly highlights many of the challenges inherent to direct detection experiments. In addition to determining the properties of the unknown dark matter particle, direct detection experiments must also consider the unknown flux of the incident dark matter, as well as uncertainties in converting a signal from one target nucleus to another. The predictions for both the CRESST 2009 run and XENON100 2010 run show an order of magnitude uncertainty. The nuclear form factor for {sup 184}W, when combined with additional theoretical and experimental uncertainties, will likely prevent CRESST from refuting the iDM hypothesis with an exposure of {Omicron}(100 kg-d) in a model-independent manner. XENON100, on the other hand, will be able to make a definitive statement about a spin-independent, inelastically scattering dark matter candidate. Still, the CRESST 2009 data can potentially confirm iDM for a large range of parameter space. In case of a positive signal, the combined data from CRESST and XENON100 will start probing the properties of the Milky Way DM profile and the interaction of the SM with the dark matter.

    The presence of pathogenic bacteria in foods has always been a great threat to the wellbeing of people and the revenue of food manufacturers. Therefore, the demand for advanced detection methods that can sensitively and rapidly detect these pathogens has been of great importance. This study reports an electrochemical biosensor for rapid detection of E. coli O157:H7 with the integration of bifunctional glucose oxidase (GOx)-polydopamine (PDA) based polymeric nanocomposites (PMNCs) and Prussian blue (PB) modified screen-printed interdigitated microelectrodes (SP-IDMEs). The core-shell magnetic beads (MBs)-GOx@PDA PMNCs were first synthesized by the self-polymerization of dopamine (DA). Gold nanoparticles (AuNPs) were dispersed on the surface of PMNCs through biochemical synthesis to achieve further highly efficient adsorption of antibodies (ABs) and GOx. The final product ABs/GOxext/AuNPs/MBs-GOx@PDA PMNCs served as the carrier to separate target bacteria from food matrices as well as the amplifier for electrochemical measurement. The unbound PMNCs were separated by a filtration step and transferred into glucose solution to allow the enzymatic reaction to occur. The change of the current response was measured with an electrochemical detector using PB-modified SP-IDMEs. The constructed biosensor has been proven to be able to detect E. coli O157:H7 with the detection limit of 10(2) cfu ml(-1). The bifunctional PMNCs contain a high load of enzyme and can optimally utilize the binding sites on bacterial cells, which efficiently amplify the signals for measurement. The biosensor in this study exhibited good specificity, reproducibility, and stability and is expected to have a great impact on applications in the detection of foodborne pathogens.

    Highlights: ► A cypermethrin CRM in green tea was developed. ► Using two isotope dilution mass spectrometry techniques for characterization. ► Certified value of 148 μg kg−1 with expanded uncertainty of ±9.2%. ► Support quality assurance of pesticide residue analysis in tea to testing. - Abstract: This paper presents the preparation of a candidate certified reference material (CRM) of cypermethrin in green tea, GLHK-11-01a according to the requirements of ISO Guide 34 and 35. Certification of the material was performed using a newly developed isotope dilution mass spectrometry (IDMS) approach, with gas chromatography high resolution mass spectrometry (GC–HRMS) and gas chromatography–tandem mass spectrometry (GC–MS/MS). Statistical analysis (one-way ANOVA) showed excellent agreement of the analytical data sets generated from the two mass spectrometric detections. The characterization methods have also been satisfactorily applied in an Asia-Pacific Metrology Program (APMP) interlaboratory comparison study. Both the GC–HRIDMS and GC–IDMS/MS methods proved to be sufficiently reliable and accurate for certification purpose. The certified value of cypermethrin in dry mass fraction was 148 μg kg−1 and the associated expanded uncertainty was 14 μg kg−1. The uncertainty budget was evaluated from sample in homogeneity, long-term and short-term stability and variability in the characterization procedure. GLHK-11-01a is primarily developed to support the local and wider testing community on need basis in quality assurance work and in seeking accreditation.

    Foodborne pathogens have continuously been a serious food safety issue and there is a growing demand for a rapid and sensitive method to screen the pathogens for on-line or in-field applications. Therefore, an impedimetric immunosensor based on the use of magnetic beads (MBs) for separation and a screen-printed interdigitated microelectrode (SP-IDME) for measurement was studied for the rapid detection of Escherichia coli O157:H7 and Salmonella Typhimurium in foods. Streptavidin coated MBs were functionalized with corresponding biotinylated antibodies (Ab) to capture the target bacteria. The glucose oxidase (GOx)-Ab conjugates were employed to label the MBs-Ab-cell complexes. The yielded MBs-Ab-cell-Ab-GOx biomass was mixed with the glucose solution to trigger an enzymatic reaction which produced gluconic acid. This increased the ion strength of the solution, thus decreasing the impedance of the solution measured on the SP-IDME. Our results showed that the immunosensor was capable of specifically detecting E. coli O157:H7 and S. Typhimurium within the range of 10(2)-10(6) cfu ml(-1) in the pure culture samples. E. coli O157:H7 in ground beef and S. Typhimurium in chicken rinse water were also examined. The limits of detection (LODs) for the two bacteria in foods were 2.05×10(3) cfu g(-1) and 1.04×10(3) cfu ml(-1), respectively. This immunosensor required only a bare electrode to measure the impedance changes, and no surficial modification on the electrode was needed. It was low-cost, reproducible, easy-to-operate, and easy-to-preserve. All these merits demonstrated this immunosensor has great potential for the rapid and on-site detection of pathogenic bacteria in foods. PMID:26653441

    Cino, B.J.

    2004-07-01

    In the booklet 'Een routekaart naar duurzame landbouw: wegen en kruispunten' (A roadmap to sustainable agriculture: roads and crossings) a line of thought is elaborated which could guide the quest for sustainable agriculture. The present study is meant to test this line of thought for its practical use. Starting-point was the idea that practitioners have already started their own quest for sustainable agriculture and that their experiences would offer food for thought. Two cases have been studied, the environmental co-operatives VEL and VANLA and the Innovatieplatform Duurzame Meierij (IDM, platform for a sustainable Meierij). In the aforementioned roadmap five dimensions are identified: why, what, where, how much and how. The present study has focused on the 'how': how do practitioners strive for sustainable agriculture. VEL and VANLA strive for a more environmentally friendly dairy farming that actively integrates nature conservation and landscape management. Ecological and economical sustainability should go hand in hand and the relationship with the other stakeholders in the area is thought to be important. Obstacles in the quest for sustainability, according to VEL and VANLA, are mainly found at the level of policy and its implementation, in the present knowledge system and in the remuneration for sustainable farm management. The IDM strives for a sustainable Meierij (Duurzame Meierij), with a focus on the rural areas. The platform checks projects using a model developed by Telos (Brabants Centre for Sustainability Issues) and in which three forms of capital are central: ecological, social-cultural and economical. Obstacles in the quest for sustainability, according to IDM, are mainly found at the level of policy and its implementation, in the price setting for sustainable products and in the perception and attitude regarding sustainability amongst urbanites, consumers and the different stakeholders of the area. Both cases are challenging

  16. Design process optimization, virtual prototyping of manufacturing, and foundry-portable DFM (Invited Paper)

    We consider modern design for manufacturing (DFM) as a manifestation of IC industry re-integration and intensive cost management dynamics. In that regard DFM is somewhat different from so-called design for yield (DFY) which essentially focuses on productivity (yield) management (that is not to say that DFM and DFY do not have significant overlaps and interactions). We clearly see the shaping of a new "full-chip DFM" infrastructure on the background of the "back to basics" design-manufacturing re-integration dynamics. In the presented work we are focusing on required DFM-efficiencies in a "foundry-fabless" link. Concepts of "virtual prototyping of manufacturing", "design process optimization", and "foundry-portable DFM" models are explored. Both senior management of the industry and leading design groups finally realize the need for a radical change of design styles. Some of the DFM super-goals are to isolate designers from process details and to make designs foundry portable. It requires qualification of designs at different foundries. In their turn, foundries specified and are implementing a set of DFM rules: "action-required", "recommended", and "guidelines" while asking designers to provide netlist and testing information. Also, we observe strong signs of innovation coming back to the mask industry. Powerful solutions are emerging and shaping up toward mask-centered IP as a business. While it seems that pure-play foundries have found their place for now in the "IDM+" model (supporting manufacturing capacity of IDMs) it is not obvious how sustainable the model is. Wafer as a production unit is not sufficient anymore; foundries are being asked by large customers to price products in terms of good die. It brings back the notion of the old ASIC business model where the foundry is responsible for dealing with both random and systematic yield issues for a given design. One scenario of future development would be that some of the leading foundries might eventually

    My successful programs have included telescope observations, hands-on activities, and edible astronomy demonstrations for: outdoor concerts or music festivals; the National Mall; churches, synagogues, seminaries, or clergy conferences; the Ronald McDonald House of Long Island (New Hyde Park, NY), the Winthrop University Hospital Children’s Medical Center (Mineola, NY); the Fresh Air Fund summer camps; a Halloween star party with costumed kids looking through telescopes; a Super Bowl Star Party; the World Science Festival (NYC); the Princeton University Science and Engineering Expo; the USA Science and Engineering Festival; and the NYC Columbus Day Parade. These outreach activities have reached thousands of people including many young girls. Information was also provided about local science museums, citizen science projects, astronomy educational sites, and astronomy clubs to encourage learning after these events. In 2010 I created Astronomy Night on the National Mall (co-sponsored the White House Office of Science and Technology Policy) with the participation of astronomy clubs, Chandra X-Ray Center, STScI, NASA, NOAO, NSF and the National Air and Space Museum.

    2012-01-01

    A study οn two neglected classical music composers suffering a not syphilitic mental disease, is attempted here, syphilis of the central nervous system being frequent in that time. A brief overview on the psychiatric ailments of many great composers reveals suicide attempts and more or less severe depression following external events. The issue of a possible relationship between mental disease and (musical) creativity can be discussed, as mood swings and a certain tendency to melancholia are frequent features of a talented brain (a fact that can also be detected in their works). The first case presented here is Hans Rott from Austria, the beloved student of Anton Bruckner, who was considered to be at least equal to his famous classmate Gustav Mahler. The great expectations of his teacher and his friends suddenly came to an end, when he suffered a crisis of schizophrenia and was hospitalized in an insane asylum in Lower Austria. The tragic psychiatric adventure of the young musician lasted almost four years. He was diagnosed as a case of "hallucinatory insanity" and "persecution mania" by the medical staff, before dying of tuberculosis, aged only 26, and having completed only one symphony and several smaller works. His name came again on surface only a century after his death, when in 1989 his Symphony in E Major was discovered and premiered with great success, permitting to its creator a posthumous recognition, among Bruckner and Mahler. The second case of mental illness is that of the Armenian Komitas Vardapet. He was an orphan who grew up in theological schools and became a monk and later a priest, though he spent some years in Berlin in order to develop his musical skills. He is considered to be an authority of Armenian ecclesiastic music, introducing polyphony in the Armenian Church's music and collecting numerous traditional songs from all parts of Armenia. In 1915, during the Armenian genocide he was deported, tortured but finally saved, due to interventions

  20. Estimating a realistic procedural blank for the determination of Fe in seawater by isotope dilution: a fundamental analytical issue

    International Nuclear Information System (INIS)

    It is well known that direct analysis of seawater by means of inductively coupled plasma mass spectrometry (ICP-MS) is hardly possible because of the salt load in the samples. Determination of the element content at ultra-trace level in open-ocean water requires a separation from the matrix associated to significant concentration factors. For iron, an isotope dilution ICP-MS method was proposed based on a multiple steps protocol, including a co-precipitation with magnesium hydroxide after ammonia loading and consecutive dissolution with hydrochloric acid. To be able to measure the iron content in the low pg g-1 range a correct assessment of the analytical procedural blank is of crucial importance. Not only this blank must be low, but also realistic (i.e. based on the complete analytical sequence applied to real iron free seawater) and reproducible. This is particularly difficult considering the ubiquity of iron and the complexity of the seawater matrix and, despite years of experiments and publications, this remains a fundamental analytical challenge and a great source of complexity for the realisation of reliable profiles of dissolved iron data. The present study considers different approaches we developed to assess, in a realistic way, the procedural blank of the IDMS method proposed by Wu and Boyle. These authors use ∼4%-sample volume for their procedural blank determination, and the results presented are rather convincing. However, down-sizing by a factor of ∼25 the sample volume, which minimizes sample-tube contact and lab ware contribution to the blank, can easily lead to changes in the analytical protocol, and thus to non-realistic procedural blank values. Instead, our investigations aimed at reproducing the full set of experimental steps involved in the determination of iron in seawater by IDMS at the nM level or below. Our results are evaluated in the light of those claimed by Wu and Boyle. The ICP-MS measurements were performed by means of a single

    Objective: To study the correlation between the T2 relaxation times of the patellar cartilage and morphological MRI findings of chondromalacia. Methods: This prospective study comprises 50 patients, 27 men and 23 women suffering of anterior knee pain (mean age: 29.7, SD 8.3 years; range: 16–45 years). MRI of 97 knees were performed in these patients at 1.5 T magnet including sagittal T1, coronal intermediate, axial intermediate fat sat and T2 mapping. Chondromalacia was assessed using a modified version of Noyes classification. The relaxation time, T2, was studied segmenting the full thickness of the patellar cartilage in 12 areas: 4 proximal (external facet–proximal–lateral (EPL), external facet–proximal–central (EPC), internal facet–proximal–central (IPC), internal facet–proximal–medial (IPM), 4 in the middle section (external facet–middle–lateral (EML), external facet–middle–central (EMC), internal facet–middle–central (IMC), internal facet–middle–medial (IMM) and 4 distal (external facet–distal–lateral (EDL), external facet–distal–central (EDC), internal facet–distal–central (IDC), internal facet–distal–medial (IDM). Results: T2 values showed a significant increase in mild chondromalacia regarding normal cartilage in most of the cartilage areas (p < 0.05), except in the internal distal facet (IDC and IDM), EPC, EDL, and IMM. Severe chondromalacia was characterized by a fall of T2 relaxation times with loss of statistical significant differences in comparison with normal cartilage, except in EMC and IMC, where similar values as mild chondromalacia were maintained (p < 0.05). Conclusions: Steepest increase in T2 values of patellar cartilage occurs in early stages of patellar cartilage degeneration. Progression of morphologic changes of chondromalacia to more severe degrees is associated to a new drop of T2 relaxation times approaching basal values in most of the areas of the patellar cartilage, except in the

    An RIA for Ep has been developed that is highly sensitive and specific. A homogeneous Ep preparation was labeled with /sup 125/I by the chloramine-T method to a specific activity of 90 to 136 ..mu..Ci/..mu..g and immunoreactivity of 80%. Ep antiserum, which was produced to a human urinary Ep preparation (80 U/mg of protein), was adsorbed with normal human urinary and serum proteins without any loss in sensitivity of the RIA to increase the specificity of the assay. A good correlation was seen between the RIA and the exhypoxic polycythemic mouse assay (corr. coef. 0.967; slope 1.05 and ''y'' intercept 0.75). Ep titers in sera from 175 hematologically normal human subjects exhibited a normal frequency distribution and ranged between 5.8 and 36.6 mU/ml with a mean of 14.9 +/- 4.7 (S.D.) and median of 14.3. Serum Ep titers were markedly elevated in seven patients with aplastic anemia and one patient with pure red cell aplasia (1350 to 20,640 mU/ml) and were lower than normal in two patients with polycythemia vera (8.1 and 9.4 mU/ml). The serum Ep titers in a prenephrectomy patient with chronic glomerulonephritis (31.1 mU/ml) decreased to below normal levels (9.04 mU/ml) after nephrectomy. The cord serum erythropoietin titers in 10 IDM (90.82 +/- 134.1 (S.D.) mu/ml) returned to values within the normal range (13.86 +/- 5.55) on day 3 after birth, suggesting the utility of the RIA in elucidating the role of hypoxia and/or insulin in increased erythropoiesis in IDM. The serum Ep titers in patients with anemias and polycythemias were compared to those of normal human subjects and agreed well with pathophysiologic mechanisms of these hemopoietic disorders, confirming the validity of the RIA.

    Highlights: • Species-unspecific ID-PAGE-LA-ICP-MS was used to quantify Alb and Tf in human serum. • Addition methods of species-unspecific {sup 34}S spike were evaluated. • Isotope change conditions were investigated to reach satisfactory “isotope equilibration”. • Human serum CRM (ERM-DA470k/IFCC) was used to validate the new arrangements. • The developed method offers potential for accurate quantification of protein by ID-PAGE-LA-ICP-MS. - Abstract: Species-specific (SS) isotope dilution analysis with gel electrophoresis (GE)-laser ablation (LA)-ICP-MS is a promising technique for the quantification of particular metal-binding proteins in biological samples. However, unavailable isotopically enriched spike and metal losses in GE separation are main limitations for SS-isotope dilution PAGE-LA-ICP-MS. In this study, we report for the first time the absolute quantification of transferrin (Tf) and albumin (Alb) in human serum by non-denaturing (native) GE combined with species-unspecific isotope dilution mass spectrometry (IDMS). In order to achieve a homogeneous distribution of both protein and isotope-enriched spike (simulated isotope equilibration), immersing the protein strips with {sup 34}S spike solution after gel electrophoresis was demonstrated to be an effective way of spike addition. Furthermore, effects of immersion time and {sup 34}S spike concentration were investigated to obtain optimal conditions of the post-electrophoresis isotope dilution method. The relative mass of spike and ablated sample (m{sub sp}/m{sub sam}) in IDMS equation was calculated by standard Tf and Alb proteins, which could be applied to the quantification of Tf and Alb in ERM-DA470k/IFCC for method confirmation. The results were in agreement with the certified value with good precision and small uncertainty (1.5–3%). In this method, species-specific spike protein is not necessary and the integrity of the heteroatom-protein could be maintained in sample preparation

    This paper presents two comparisons or tests for a Lagrangian model of zooplankton dispersion: numerical schemes and time steps. Firstly, we compared three numerical schemes using idealized circulations. Results show that the precisions of the advanced Adams-Bashfold-Moulton (ABM) method and the Runge-Kutta (RK) method were in the same order and both were much higher than that of the Euler method. Furthermore, the advanced ABM method is more efficient than the RK method in computational memory requirements and time consumption. We therefore chose the advanced ABM method as the Lagrangian particle-tracking algorithm. Secondly, we performed a sensitivity test for time steps, using outputs of the hydrodynamic model, Symphonie. Results show that the time step choices depend on the fluid response time that is related to the spatial resolution of velocity fields. The method introduced by Oliveira et al. in 2002 is suitable for choosing time steps of Lagrangian particle-tracking models, at least when only considering advection.

  6. Reassessing the Gravity’s Rainbow Pynchon Wiki: a new research paradigm?

    2012-07-01

    Full Text Available Since the 'Against the Day 'Wiki launched in October 2006, the Pynchon Wiki collection has received over twenty thousand edits, making it one of the largest, dedicated literary reference Wikis. One can now view and add annotations to all seven of Pynchon’s novels – only 'Slow Learner 'and his non-fiction remain 'sans 'Wiki -, and a loose community of over four hundred contributors have done so. This paper will assess the importance of the 'Gravity’s Rainbow 'Wiki in transforming understanding and interpretation through asking four different questions: does the Wiki count as a disruptive force in the Pynchon interpretive industry, who contributes to the Wiki, what types of contribution they make, and how do they exploit the hypertextual features on offer through the MediaWiki package. I will suggest that the Pynchon Wiki does not fully depart from old media forms of interpretation and remains fragmented in both community, resembling a symphony of soloists, and potential connections. This is a version of Web 2.0 synthesizing both Darcy DiNucci’s original dystopian vision of fragmentation (DiNucci and Tim O’Reilly’s utopian idea of harnessing ‘collective intelligence’ (O’Reilly.

  7. A multimodal behavioral approach to performance anxiety.

    2004-08-01

    Cognitive-behavior therapy (CBT) stresses a trimodal assessment framework (affect, behavior, and cognition [ABC]), whereas the multimodal approach assesses seven discrete but interactive components--behavior, affect, sensation, imagery, cognition, interpersonal relationships, and drugs/biological factors (BASIC I.D.). Only complex or recalcitrant cases call for the entire seven-pronged range of multimodal interventions. Various case illustrations are offered as examples of how a clinician might proceed when confronted with problems that fall under the general heading of performance anxiety. The main example is of a violinist in a symphony orchestra whose career was in serious jeopardy because of his extreme fear of performing in public. He responded very well to a focused but elaborate desensitization procedure. The hierarchy that was eventually constructed contained many dimensions and subhierarchies featuring interlocking elements that evoked his anxiety. In addition to imaginal systematic desensitization, sessions were devoted to his actual performance in the clinical setting. As a homework assignment, he found it helpful to listen to a long-playing record of an actual rehearsal and to play along with the world-renowned orchestra and conductor. The subsequent disclosure by the client of an important sexual problem was dealt with concomitantly by using a fairly conventional counseling procedure. Therapy required 20 sessions over a 3-month period. PMID:15241811

    2011-06-01

    The rôle of astronomy in the Brazilian cultural diversity -though little known world- has been enormous. Thus, the different forms of popular music and erudite, find musical compositions and lyrics inspired by the stars, the eclipses in rare phenomena such as the transit of Venus in front of the sun in 1882, the appearance of Halley's Comet in 1910, in the Big Bang theory. Even in the carnival parades of the blocks at the beginning of the century astronomy was present. More recently, the parade of 1997, the samba school Unidos do Viradouro, under the direction of Joãozinho Trinta, offered a new picture of the first moments of the creation of the universe to join in the white and dark in the components of their school, the idea of matter and anti-matter that reigned in the early moments of the creation of the universe in an explosion of joy. Examples in classical music include Dawn of Carlos Gomes and Carta Celeste by Almeida Prado. Unlike The Planets by Gustav Holst -who between 1914 and 1916 composed a symphonical tribute to the solar system based on astrology- Almeida Prado composed a symphony that is not limited to the world of planets, penetrating the deep cosmos of galaxies.

    The authors note that the element of sound and music has no place in the model of mental functioning bequeathed to us by Freud, which is dominated by the visual and the representational. They consider the reasons for this exclusion and its consequences, and ask whether the simple biographical explanation offered by Freud himself is acceptable. This contribution reconstructs the historical and cultural background to that exclusion, cites some relevant emblematic passages, and discusses Freud's position on music and on the aesthetic experience in general. Particular attention is devoted to the relationship between Freud and Lipps, which is important both for the originality of Lipps's thinking in the turn-of-the-century debate and for his ideas on the musical aspects of the foundations of psychic life, at which Freud 'stopped', as he himself wrote. Moreover, the shade of Lipps accompanied Freud throughout his scientific career from 1898 to 1938. Like all foundations, that of psychoanalysis was shaped by a system of inclusions and exclusions. The exclusion of the element of sound and music is understandable in view of the cultural background to the development of the concepts of the representational unconscious and infantile sexuality. While the consequences have been far reaching, the knowledge accumulated since that exclusion enables us to resume, albeit on a different basis, the composition of the 'unfinished symphony' of the relationship between psychoanalysis and music.

    2001-05-01

    How does acoustics affect the symphonic music performed in a concert hall? The lecture begins with an illustrated discussion of the architectural features that influence the acoustics. Boston Symphony Hall, which was built in 1900 when only one facet of architectural design was known, now rates as one of the world's great halls. How this occurred will be presented. Music is composed with some acoustical environment in mind and this varies with time from the Baroque to the Romantic to the Modern musical period. Conductors vary their interpretation according to the hall they are in. Well-traveled listeners and music critics have favorite halls. The lecture then presents a list of 58 halls rank ordered according to their acoustical quality based on interviews of music critics and conductors. Modern acoustical measurements made in these halls are compared with their rankings. Music recordings will be presented that demonstrate how halls sound that have different measured acoustical parameters. Photographs of a number of recently built halls are shown as examples of how these known acoustical factors have been incorporated into architectural design.

The coupling of waves and currents has been done considering four main processes: wave refraction due to currents, surface wind drag and bo€ttom drag modifications due to waves, and the wave induced mass flux. The coupled modelling system is implemented in the southern Catalan shelf (NW Mediterranean, a region with characteristics similar to most of the Mediterranean shelves. The sensitivity experiments are run in a typical operational configuration. The wave refraction by currents seems to be not very relevant in a microtidal context such as the western Mediterranean. The main effect of waves on current forecasts is through the modification of the wind drag. The Stokes drift also plays a significant role due to its spatial and temporal characteristics. Finally, the enhanced bottom friction is just noticeable in the inner shelf.

    Purpose: The aim of our study was to compare the value of cardiac DECT (cDECT) for detection of myocardial iron deposition to T2*w cardiac MRI (cMRI). Material and methods: Nineteen patients with clinical history of Thalassaemia underwent T2*-weighted cardiac MRI (cMRI) with a 1.5 T MR scanner (MAGNETOM Symphony, Siemens Medical Solutions, Erlangen, Germany) and cardiac dual energy CT (cDECT) with a DSCT scanner (SOMATOM Definition, Siemens Medical Solutions, Erlangen, Germany) on the same day. HU values obtained from cDECT scans and T2*-values from cMRI were statistically correlated to calculate significance levels. Table times were measured for both cDECT and cMRI and compared. Patients were asked to grade their subjective comfort during the examination. Results: In all patients cDECT scans were successfully acquired. HU values of septal muscle correlated strongly with T2*-values, whereas no correlation was found for paraspinal muscle. Table time was significantly shorter for cDECT compared to cMRI (mean: 3.7 min vs. 11.2 min) and subjective patient comfort was rated comfortable for cDECT and average to poor for cMRI. Mean radiation dose was 0.71 mSv. Conclusion: cDECT scans seem to be possible for evaluation of myocardial iron load in pediatric Thalassaemia patients.

    Full Text Available Introduction. Functional disorders of the pelvic floor represent have a significant impact on the quality of life. The advent of open-configuration systems allowed for the evaluation of defecation with MR imaging in sitting position. The purpose of the present study is to compare the results of static and dynamic pelvic MR performed in supine position versus sitting position, using a new MR prototype machine, in the diagnosis of pelvic floor descent. Materials and Methods. Thirty-one patients with pelvic floor disorders were enrolled, and underwent MR Defecography in supine position with 1.5 T closed magnet (MAGNETOM Symphony, Siemens, Germany and in sitting position with a 0.25-Tesla open magnet system (G-Scan ESAOTE, Italy. Results. In rest and squeezing phases, positions of bladder, vagina, and ARJ were significantly different when the patient was imaged in supine versus sitting position. In the defecation phase, a significant difference for the bladder and vagina position was detected between the two exams whereas a significant difference for the ARJ was not found. A statistically significant difference exists when the pelvic floor descent is evaluated in sitting versus supine position. Conclusion. Our results show that MR Defecography in sitting position may represent a useful tool to correctly diagnose and grade the pelvic organ descent.

    Cuillandre, J. C.

    Canada-France-Hawaii Telescope Corp. The summit of Mauna Kea (14,000 feet) offers the best viewing of the Cosmos in the northern hemisphere, and the film "Hawaiian Starlight" delivers a pure esthetic experience from the mountain into the Universe. Seven years in the making, this cinematic symphony reveals the spectacular beauty of the mountain and its connection to the Cosmos through the magical influence of time-lapse cinematography scored exclusively (no narration) with the awe-inspiring, critically acclaimed, Halo music by Martin O'Donnell and Michael Salvatori. Daytime and nighttime landscapes and skyscapes alternate with stunning true color images of the Universe captured by an observatory on Mauna Kea, all free of any computer generated imagery. An extended segment of the film will be presented at the Advanced Maui Optical and Space Surveillance Technologies Conference to celebrate the international year of Astronomy 2009, a global effort initiated by the IAU (International Astronomical Union) and UNESCO (United Nations Educational, Scientific and Cultural Organization) to help the citizens of the world rediscover their place in the Universe through the day- and night-time sky, and thereby engage a personal sense of wonder and discovery. Hawaiian Starlight is true to this commitment. The inspiration and technology of the film will be shortly presented by the film's director.

  3. Off the beaten track: Freud, sound and music. Statement of a problem and some historico-critical notes.

    The authors note that the element of sound and music has no place in the model of mental functioning bequeathed to us by Freud, which is dominated by the visual and the representational. They consider the reasons for this exclusion and its consequences, and ask whether the simple biographical explanation offered by Freud himself is acceptable. This contribution reconstructs the historical and cultural background to that exclusion, cites some relevant emblematic passages, and discusses Freud's position on music and on the aesthetic experience in general. Particular attention is devoted to the relationship between Freud and Lipps, which is important both for the originality of Lipps's thinking in the turn-of-the-century debate and for his ideas on the musical aspects of the foundations of psychic life, at which Freud 'stopped', as he himself wrote. Moreover, the shade of Lipps accompanied Freud throughout his scientific career from 1898 to 1938. Like all foundations, that of psychoanalysis was shaped by a system of inclusions and exclusions. The exclusion of the element of sound and music is understandable in view of the cultural background to the development of the concepts of the representational unconscious and infantile sexuality. While the consequences have been far reaching, the knowledge accumulated since that exclusion enables us to resume, albeit on a different basis, the composition of the 'unfinished symphony' of the relationship between psychoanalysis and music.

    Hans von Bülow (1830-1894) was a conductor and pianist of worldwide reputation and founder of many stylistic interpretations of classic and romantic symphonies. The close friendship with Richard Wagner, but not the enthusiastic admiration of his dramatic musical opus, ended abruptly when Hans von Bülow became aware of the betrayal of his wife Cosima and Richard Wagner. Hans von Bülow reported symptoms and signs of neurological disease in many letters that were kept and edited by his second wife Marie. For decades he suffered from chronic neuralgiforme headaches, which were caused by a tumor of the cervical radicular nerves. At the age of 45 years, he suddenly developed a motorsensory deficit in the right arm and hand and a contralateral facial deficit, suggestive of brainstem infarction. He recovered and celebrated even greater successes as a musician, although phases of major depression also interfered with his professional life. In the last, phase of his life, he experienced the consequences of generalized atherosclerosis and cerebral microangiopathy. It was a second cerebrovascular accident of the brainstem that caused his death, only 10 months after his last concert performance. Although his death occurred in Egypt, an autopsy was performed by Professor Ludwig Edinger and the results will be presented. PMID:17495513

  5. The role of estradiol in male reproductive function

    Full Text Available Traditionally, testosterone and estrogen have been considered to be male and female sex hormones, respectively. However, estradiol, the predominant form of estrogen, also plays a critical role in male sexual function. Estradiol in men is essential for modulating libido, erectile function, and spermatogenesis. Estrogen receptors, as well as aromatase, the enzyme that converts testosterone to estrogen, are abundant in brain, penis, and testis, organs important for sexual function. In the brain, estradiol synthesis is increased in areas related to sexual arousal. In addition, in the penis, estrogen receptors are found throughout the corpus cavernosum with high concentration around neurovascular bundles. Low testosterone and elevated estrogen increase the incidence of erectile dysfunction independently of one another. In the testes, spermatogenesis is modulated at every level by estrogen, starting with the hypothalamus-pituitary-gonadal axis, followed by the Leydig, Sertoli, and germ cells, and finishing with the ductal epithelium, epididymis, and mature sperm. Regulation of testicular cells by estradiol shows both an inhibitory and a stimulatory influence, indicating an intricate symphony of dose-dependent and temporally sensitive modulation. Our goal in this review is to elucidate the overall contribution of estradiol to male sexual function by looking at the hormone′s effects on erectile function, spermatogenesis, and libido.

  7. Status and tendencies for low to medium thrust propulsion systems

    Hopmann, Helmut; Pitt, Richard; Schwende, Manfred; Zewen, Helmut

    The previous use of space liquid propulsion systems in the low thrust range (up to approx. 400 N) has been almost entirely devoted to providing the attitude and orbit control of satellites, including apogee injection. The use of hydrazine peroxide gave way to monopropellant hydrazine in the late sixties whilst the advent of bipropellant systems came with the launch of the Symphonie satellite in 1974. In general, these propulsion systems, together with their feed system components, are more or less standardized with only minor changes required in terms of configuration or propellant mass (tank size) for each satellite. The future, however, promises much greater diversification for the low and medium thrust propulsion systems with increasing technical demands on the engines and their associated equipment. Space Station programs, like Columbus with its in-orbit servicing requirement, will require longer life components and increased modularity whilst manned launch vehicles, such as Ariane 5 with Hermes or Space Planes such as Sänger or Hotol, will demand much higher safety and reliability requirements together with maximum reusability.

  8. Physics For All -- yes, it's real physics

    Can ``all'' students learn ``real'' physics? We want to provide instruction to a wider segment of the population including those students who will not go into STEM (Science, Technology, Engineering, Math) careers. We also want to maintain the integrity of physics, challenge all students, and not compromise the rigor of our courses. Accomplishing this requires a research guided approach to instruction, curriculum and assessment. Physics First and Physics for All have become a success story for thousands of students in urban, suburban, and rural districts. At the same time, the International Physics Olympiad and other competitions have raised the expectation of what the most motivated students can achieve. Many physics educators are exploring ways to set higher goals for our most gifted students while also providing physics instruction to students previously excluded from our physics classes. Many of the same issues that K-12 educators are struggling with are equally important to the college community as colleges try to educate both future physicists and an educated citizenry. Great novels and symphonies are accessible to people of different backgrounds and levels of expertise. We should develop strategies that enable us to share an understanding of physics with all students because everyone deserves an opportunity to reflect on the wondrous workings of our universe.

  9. Concert halls with strong and lateral sound increase the emotional impact of orchestra music.

    2016-03-01

    An audience's auditory experience during a thrilling and emotive live symphony concert is an intertwined combination of the music and the acoustic response of the concert hall. Music in itself is known to elicit emotional pleasure, and at best, listening to music may evoke concrete psychophysiological responses. Certain concert halls have gained a reputation for superior acoustics, but despite the continuous research by a multitude of objective and subjective studies on room acoustics, the fundamental reason for the appreciation of some concert halls remains elusive. This study demonstrates that room acoustic effects contribute to the overall emotional experience of a musical performance. In two listening tests, the subjects listen to identical orchestra performances rendered in the acoustics of several concert halls. The emotional excitation during listening is measured in the first experiment, and in the second test, the subjects assess the experienced subjective impact by paired comparisons. The results showed that the sound of some traditional rectangular halls provides greater psychophysiological responses and subjective impact. These findings provide a quintessential explanation for these halls' success and reveal the overall significance of room acoustics for emotional experience in music performance. PMID:27036257

    Television viewing (TVV) has been linked with obesity, possibly through increased sedentary behavior and/or through increased ingestion during TVV. The proposition that TVV causes increased feeding, however, has not been subjected to experimental verification until recently. Our objective was to determine if the amount eaten of two familiar, palatable, high-density foods (pizza and macaroni and cheese) was increased during a 30-min meal when watching TV. In a within-subjects design, one group of undergraduates (n = 10) ate pizza while watching a TV show of their choice for one session and when listening to a symphony during the other session. A second group of undergraduates (n = 10) ate macaroni and cheese (M&C). TVV increased caloric intake by 36% (one slice on average) for pizza and by 71% for M&C. Eating patterns also differed between conditions. Although the length of time to eat a slice of pizza remained stable between viewing conditions, the amount of time before starting another slice was shorter during TVV. In contrast, M&C was eaten at a faster rate and for a longer period of time during TVV. Thus, watching television increases the amount eaten of high-density, palatable, familiar foods and may constitute one vector contributing to the current obesity crisis. PMID:16822530

    Synchrotron emission and absorption determine the observational appearances of many astronomical systems. In this paper, we describe a numerical scheme for calculating synchrotron emissivities and absorptivities in all four Stokes parameters for arbitrary gyrotropic electron distribution functions, building on earlier work by Leung, Gammie, and Noble. We use this technique to evaluate the emissivities and the absorptivities for a thermal (Maxwell–Jüttner), isotropic power-law, and an isotropic kappa distribution function. The latter contains a power-law tail at high particle energies that smoothly merges with a thermal core at low energies, as is characteristic of observed particle spectra in collisionless plasmas. We provide fitting formulae and error bounds on the fitting formulae for use in codes that solve the radiative transfer equation. The numerical method and the fitting formulae are implemented in a compact C library called symphony. We find that the kappa distribution has a source function that is indistinguishable from a thermal spectrum at low frequency and transitions to the characteristic self-absorbed synchrotron spectrum, \\propto {ν }5/2, at high frequency; the linear polarization fraction for a thermal spectrum is near unity at high frequency; and all distributions produce O(10%) circular polarization at low frequency for lines of sight sufficiently close to the magnetic field vector.

    Echo-planar magnetic resonance imaging (EP-MRI), which is novel variant of MRI, is thought to have antidepressant properties in humans and animal models. Using the forced swimming test (FST), we investigated which monoaminergic system in mice is affected by EP-MRI. The short- and long-term effects of EP-MRI on immobility time in the FST and motor activity within a locomotor activity cage were examined. Two groups of mice underwent 20 min of EP-MRI in an MR scanner (Siemens, 1.5 T Symphony) either 23.5 or 1 h before the start of the second session of the FST. In both groups, the immobility duration in the FST was reduced, similar to effective antidepressant drug treatments. Climbing behavior in the 1-h group and swimming behavior in the 23.5-h group increased significantly, similar to that seen after the administration of desipramine (a noradrenaline reuptake inhibitor) and sertraline (a selective serotonin reuptake inhibitor), respectively. The findings support the hypothesis that EP-MRI has an antidepressant-like effect. We suggest that the antidepressant-like effect begins in the early period with noradrenaline systems and is maintained in the late period with serotonin systems.

    Full Text Available Current studies on Adolph Bernhard Marx generally focus on Marx’s seminal texts in music theory and pedagogy, such as Die Lehre von der musikalischen Komposition, praktisch theoretisch (1837–1847 and Marx’s theory of sonata form, but they infrequently explore the philosophical and aesthetic dimensions of Marx’s criticism. The present essay will analyze a series of statements Marx wrote that address the aesthetic principles one should employ in descriptions of musical meaning, including “spiritual guidelines” (die geistigen Lenkfäden and psychological coherence (des psychologischen Zusammenhangs. We will investigate Hegel’s influence on Marx’s thought, in addition to other contemporary philosophical positions, in relation to the themes of musical content, form, and the creative process. The study will aim to reveal the function of “spiritual guidelines” and specifically psychological coherence in aesthetics as the basis of a fresh look into musical meaning and ideal content in Beethoven’s Ninth Symphony, Op. 125.

  18. Concert halls with strong lateral reflections enhance musical dynamics.

    Pätynen, Jukka; Tervo, Sakari; Robinson, Philip W; Lokki, Tapio

    2014-03-25

    One of the most thrilling cultural experiences is to hear live symphony-orchestra music build up from a whispering passage to a monumental fortissimo. The impact of such a crescendo has been thought to depend only on the musicians' skill, but here we show that interactions between the concert-hall acoustics and listeners' hearing also play a major role in musical dynamics. These interactions contribute to the shoebox-type concert hall's established success, but little prior research has been devoted to dynamic expression in this three-part transmission chain as a complete system. More forceful orchestral playing disproportionately excites high frequency harmonics more than those near the note's fundamental. This effect results in not only more sound energy, but also a different tone color. The concert hall transmits this sound, and the room geometry defines from which directions acoustic reflections arrive at the listener. Binaural directional hearing emphasizes high frequencies more when sound arrives from the sides of the head rather than from the median plane. Simultaneously, these same frequencies are emphasized by higher orchestral-playing dynamics. When the room geometry provides reflections from these directions, the perceived dynamic range is enhanced. Current room-acoustic evaluation methods assume linear behavior and thus neglect this effect. The hypothesis presented here is that the auditory excitation by reflections is emphasized with an orchestra forte most in concert halls with strong lateral reflections. The enhanced dynamic range provides an explanation for the success of rectangularly shaped concert-hall geometry.

  19. The first vineyard concert hall in North America

    2002-11-01

    The first vineyard or surround concert hall designed and built in the Western Hemisphere is the Sala Nezahualcoyotl in Mexico City. The Hall was completed in 1976 and is part of the Cultural Center at the Universidad Nacional Autonoma de Mexico. The hall was named after a Toltec poet, architect, and musician who lived in the 15th century and was the Renaissance man of his day. In order to provide the familiar traditional sound of the rectangular (shoebox) European Hall, the acoustic designers set the criteria for reverberation times through the frequency spectrum and the Initial Time Delay Gap at every seat in the house to match the measurements taken at the Grosser Musik vereinssaal in Vienna and Boston Symphony Hall. In this paper we discuss the techniques used to create the traditional sound in a vineyard hall and the reaction of musicians and audiences to the completed facility. The Sala was the model for Suntory Hall in Japan which in turn spawned a number of vineyard halls in Japan. Most recently, the vineyard style seems to be appealing to more and more symphonic organizations in Europe and North America.

  20. Differential diagnosis of benign and malignant breast lesions by combination of enhanced dynamic MRI and diffusion weighted MRI. Examination by ROC analysis

    International Nuclear Information System (INIS)

    A highly improved differential diagnosis of benign and malignant breast lesions by combination of MR-spectroscopy and enhanced dynamic (ED) MRI has been reported but the former imaging requires as long as 12-20 min. The present examination is performed to know whether combination of ED MRI and diffusion weighted (DW) MRI which is done within 40-100 sec, can also have the high diagnostic accuracy. Objects are 226 lesion images of 219 women of the average age of 54.3 y, whose histopathological observation is conducted on tissues obtained by surgery or biopsy after imaging. MRI machine is Siemens 1.5 T Symphony with the coil specific for mammary gland and imaging is done in the order of short inversion time inversion recovery (STIR), DW, and ED with gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA). Images are evaluated by 2 experts according to breast imaging reporting and data system (BI-RADS) MRI of American College of Radiology; detectability, by reference to pathological findings; and differential, by ROC (receiver operating characteristics) analysis (ROCFIT program) and Mc-Nemar test. Pathological diagnosis gives 196 malignant and 30 benign lesions. DW MRI is found to be only subsidiary for differential examination of malignant and benign lesions. (R.T.)

  1. When Stars Attack! Live Radioactivities as Geological Signatures of Nearby Supernova Explosions

    Fields, Brian D.

    2007-05-01

    The lifespans of the most massive stars are a symphony of the fundamental forces, culminating in a spectacular and violent supernova explosion. While these events are awesome to observe, they can take a more sinister shade when they occur closer to home, because an explosion inside a certain "minimum safe distance" would pose a grave threat to life on Earth. We will discuss these cosmic insults to life, and ways to determine whether a supernova occurred nearby over the course of the Earth's existence. We will then present recent evidence that a star exploded near the Earth about 3 million years ago. Radioactive iron-60 atoms have been found in ancient samples of deep-ocean material, and are likely to be debris from this explosion. Recent data confirm this radioactive signal, and for the first time allow sea sediments to be used as a telescope, probing the nuclear reactions that power exploding stars. Furthermore, an explosion so close to Earth was probably a "near-miss," which emitted intense and possibly harmful radiation. The resulting environmental damage may even have led to extinction of species which were the most vulnerable to this radiation.

  2. System Dynamics

    Science.gov (United States)

    Morecroft, John

    System dynamics is an approach for thinking about and simulating situations and organisations of all kinds and sizes by visualising how the elements fit together, interact and change over time. This chapter, written by John Morecroft, describes modern system dynamics which retains the fundamentals developed in the 1950s by Jay W. Forrester of the MIT Sloan School of Management. It looks at feedback loops and time delays that affect system behaviour in a non-linear way, and illustrates how dynamic behaviour depends upon feedback loop structures. It also recognises improvements as part of the ongoing process of managing a situation in order to achieve goals. Significantly it recognises the importance of context, and practitioner skills. Feedback systems thinking views problems and solutions as being intertwined. The main concepts and tools: feedback structure and behaviour, causal loop diagrams, dynamics, are practically illustrated in a wide variety of contexts from a hot water shower through to a symphony orchestra and the practical application of the approach is described through several real examples of its use for strategic planning and evaluation.

    Being an important carrier, the Chinese traditional landscape architecture mingles the ideas of Confucianism, Taoism and Buddhism, as well as the materialization of the traditional scholar idea of three religion unity. People may feel these invisible ideas from the landscape architecture elements. The soundscape unites nature with humanity culture, which includes natural wind, rain, the sound of water, bugs, and birds, and even the musical sound and Chinese opera. Thus soundscape forms the natural and humanistic harmonious blend of wonderful symphony, uniting the traditional landscape architecture surroundings.%中国传统园林作为传统文化的重要载体,儒、道、佛思想体系交融渗透其中,恰似“三教合一”的传统文人思想的物化.人们可以从园林的组成元素中感受到这些无形的思想理念.声景的构成集自然与人文景观于一体,有自然的风声、雨声、水声及虫鸟之声,更有古琴之韵与戏曲之境.由此构成的园林声景,与古典园林的环境浑然一体,构成了自然与人文和谐交融的绝妙交响曲.

  4. Urban sound ecologies

    2013-12-01

    Full Text Available Within recent years, there has been a renewed focus on sound in urban environments. From sound installations in public space to sound festivals in alternative settings, we find a common interest in sound art relating to the urban environment. Artworks or interventions presented in such contexts share the characteristics of site specificity. However, this article will consider the artwork in a broader context by re-examining how sound installations relate to the urban environment. For that purpose, this article brings together ecology terms from acoustic ecology of the sound theories of the 1970s while developing them into recent definitions of ecology in urban studies. Finally, we unfold our framing of urban sound ecologies with three case analyses: a sound intervention in Berlin, a symphony for wind instruments in Copenhagen and a video walk in a former railway station in Kassel. The article concludes that the ways in which recent sound installations work with urban ecologies vary. While two of the examples blend into the urban environment, the other transfers the concert format and its mode of listening to urban space. Last, and in accordance with recent soundscape research, we point to how artists working with new information and media technologies create inventive ways of inserting sound and image into urban environments.

  6. Celebrating 24 years of Public Outreach of Science and Engineering in Portland Oregon

    Science.gov (United States)

    Bristol, Terry

    2012-02-01

    There have been several core strategies in our highly successful 24-year Science, Technology and Society outreach program. However, the strategy for each season is also dynamic, requiring innovation and novel coalitions. As Bob Dylan put it so succinctly, ``He not busy being born is busy dying.'' Public outreach programs - as the Chautauquas of the past - should be positioned in the cultural milieu along with the opera, symphony and theatre. Support for the enterprise needs to be a broad and diverse coalition, based ideally on the creative formation of win-win relationship. You want people to see your success as their success: ``Together we can enhance the intellectual environment in ways that none of us could do alone.'' Being multi-disciplinary presents challenges but has considerable advantages. For instance, enlightened managers of established organizations recognize the value of exposing their employees to a diversity of problem solving approaches. Instead of inviting speakers for one large lecture we now invite them to be Resident Scholars for two-three days and develop a range of additional smaller public engagements. Science and engineering topics must be relevant - placed in the broader Science, Technology and Society framework. We avoid ``gee-whiz'' in favor of what stimulates reflection on who we are, where we came from, and our role in the universe. I will briefly review how we have survived and thrived and, finally, what I see as future trends and opportunities.

    Full Text Available The article considers the noise as the most important category of media culture, its ontology and gnoseological quality, impact ways and possible forms of study. "Noisology" is offered like a separate direction in the science of sound. Today, there are systems of learning and teaching of speech and music, but we are not trained to understand or decipher the noises. We often resort to our own empirical experience when talking about noise or trying to identify it, describe its semantics, symbols or imagery. In the media artistic creation and production of the XX-XXI centuries, the role of the noise is not in doubt. "Music for percussion", "symphonies of noises", noise soundtracks, noisomusic, ars-acoustic, noise tools, data bases of noises and sound-engineering practice of audio effects, all can be confirmation of this phenomena. So, applied mission of art noises requires scientific understanding. Therefore the noisology presents three central topics: noise psychoacoustics, noise semiotics, and noise imagery including its "musicality".

    2012-01-01

    Objectives This study (a) examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of three contrasting types of background music, and (b) compared performance based upon listener groups: CI recipients using conventional long-electrode (LE) devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing (NH) adults. Methods We tested 154 LE CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 NH adults on closed-set recognition of spondees presented in three contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Outcomes Signal-to-noise thresholds for speech in music (SRTM) were examined in relation to measures of speech recognition in background noise and multi-talker babble, pitch perception, and music experience. Results SRTM thresholds varied as a function of category of background music, group membership (LE, Hybrid, NH), and age. Thresholds for speech in background music were significantly correlated with measures of pitch perception and speech in background noise thresholds; auditory status was an important predictor. Conclusions Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music. PMID:23342550

    My NASA-funded Music and Astronomy Under the Stars (MAUS) has brought astronomy to 50,000 music lovers at the National Mall (co-sponsor OSTP); Central Park Jazz, Newport Folk, Ravinia, or Tanglewood music festivals; and classical, folk, pop/rock, opera, Caribbean, or county-western concerts in parks assisted by astronomy clubs (55 events since 2009). Yo-Yo-Ma, the Chicago and Boston Symphony Orchestras, Ravi Coltrane, Esperanza Spalding, Phish, Blood Sweat and Tears, Deep Purple, Tony Orlando, and Wilco performed at these events. MAUS combines solar, optical, and radio telescope observations; large posters/banners (From the Earth to the Universe; Visions of the Universe); videos; hands-on activities (Night Sky Network; Harvard-Smithsonian CfA); imaging with a cell phone mount; and hand-outs (info on science museums, astronomy clubs, and citizen science) before and after the concerts or at intermission. MAUS reached underserved groups and attracted large enthusiastic crowds. Many young children participated in this family learning experience-often the first time they looked through a telescope. Outcomes: While < 50% of the participants took part in a science museum or activity in the past year (survey result), they found MAUS enjoyable and understandable; learned about astronomy; wanted to learn more; and increased their interest in science (ave. rating 3.6/4). Taking science directly to people is effective in promoting science education!

  13. World Energy Scenarios: Composing energy futures to 2050

    International Nuclear Information System (INIS)

    The World Energy Scenarios: Composing energy futures to 2050 is the result of a three-year study conducted by over 60 experts from nearly 30 countries, with modelling provided by the Paul Scherrer Institute. The report assesses two contrasting policy scenarios, the more consumer driven Jazz scenario and the more voter-driven Symphony scenario with a key differentiator being the ability of countries to pass through the Doha Climate Gateway. The WEC scenarios use an explorative approach to assess what is actually happening in the world now, to help gauge what will happen in the future and the real impact of today's choices on tomorrow's energy landscape. Rather than telling policy-makers and senior energy leaders what to do in order to achieve a specific policy goal, the WEC's World Energy Scenarios allow them to test the key assumptions that decision-makers decide to better shape the energy of tomorrow This document includes the French and English versions of the executive summary and the English version of the full report

  14. Information Needs for a Purchase of Fairtrade Coffee

    2015-05-01

    Full Text Available This research investigates what information German Fairtrade coffee consumers search for during pre-purchase information seeking and to what extent information is retrieved. Furthermore, the sequence of the information search as well as the degree of cognitive involvement is highlighted. The role of labeling, the importance of additional ethical information and its quality in terms of concreteness as well as the importance of product price and organic origin are addressed. A set of information relevant to Fairtrade consumers was tested by means of the Information Display Matrix (IDM method with 389 Fairtrade consumers. Results show that prior to purchase, information on product packages plays an important role and is retrieved rather extensively, but search strategies that reduce the information processing effort are applied as well. Furthermore, general information is preferred over specific information. Results of two regression analyses indicate that purchase decisions are related to search behavior variables rather than to socio-demographic variables and purchase motives. In order to match product information with consumers’ needs, marketers should offer information that is reduced to the central aspects of Fairtrade.

    Full Text Available Current research studied the effect of partial replacing corn by glycerin and essential oils addition in the diet of Nellore bulls finished in feedlot on feed intake, animal performance and three markers were assessed to estimate apparent digestibility. Thirty bulls with average weight 400 ± 34.1 kg and 22 ± 2 months old were housed in collective pens (10 x 20 m2 for 63 days. The bulls were randomly assigned to 3 diets (10 bulls per treatment: CON – Control (without glycerin or Essential® oils; GLY – Glycerin (15% on dry matter - DM; and GEO – Glycerin (15% on DM and Essential® oils (3 g animal day-1. Three different markers were used to estimate apparent digestibility in the diets: indigestible dry matter –iDM; indigestible neutral detergent fiber – iNDF; and purified lignin – LIPE®. Feed efficiency and animal performance were not affected by the corn partial replacing by glycerin. No effects were found in partial corn replacing by glycerin and Essential® oils addition in the diets on the fecal output, crude protein and ether extract digestibility among the diets. The DM and OM apparent digestibility were higher for bulls fed with glycerin and Essential® oils. The CHO digestibility was higher for CON diet. The markers iDM, iNDF and LIPE® were similarly to estimate apparent digestibility to all nutrients in the diets.

    Christopher, Steven J; Vetter, Thomas W

    2016-05-01

    In recent years, microwave-induced combustion (MIC) has proved to be a robust sample preparation technique for difficult-to-digest samples containing high carbon content, especially for determination of halogens and sulfur. National Institute of Standards and Technology (NIST) has applied the MIC methodology in combination with isotope dilution analysis for sulfur determinations, representing the first-reported combination of this robust sample preparation methodology and high-accuracy quantification approach. Medium-resolution mode sector-field inductively coupled plasma mass spectrometry was invoked to avoid spectral interferences on the sulfur isotopes. The sample preparation and instrumental analysis scheme was used for the value assignment of total sulfur in Standard Reference Material (SRM) 2682c Subbituminous Coal (nominal mass fraction 0.5% sulfur). A description of the analytical procedures required is provided, along with metrological results, including an estimation of the overall method uncertainty (<1.5% relative expanded uncertainty) calculated using the IDMS measurement function and a Kragten spreadsheet approach.

  19. An Event Driven Hybrid Identity Management Approach to Privacy Enhanced e-Health

    Directory of Open Access Journals (Sweden)

    Fabio Sanvido

    2012-05-01

    Full Text Available Credential-based authorization offers interesting advantages for ubiquitous scenarios involving limited devices such as sensors and personal mobile equipment: the verification can be done locally; it offers a more reduced computational cost than its  competitors for issuing, storing, and verification; and it naturally supports rights delegation. The main drawback is the revocation of rights. Revocation requires handling potentially large revocation lists, or using protocols to check the revocation status, bringing extra communication costs not acceptable for sensors and other limited devices. Moreover, the effective revocation consent—considered as a privacy rule in sensitive scenarios—has not been fully addressed. This paper proposes an event-based mechanism empowering a new concept, the sleepyhead credentials, which allows to substitute time constraints and explicit revocation by activating and deactivating authorization rights according to events. Our approach is to integrate this concept in IdM systems in a hybrid model supporting delegation, which can be an interesting alternative for scenarios where revocation of consent and user privacy are critical. The delegation includes a SAML compliant protocol, which we have validated through a proof-of-concept implementation. This article also explains the mathematical model describing the event-based model and offers estimations of the overhead introduced by the system. The paper focus on health care scenarios, where we show the flexibility of the proposed event-based user consent revocation mechanism.

  20. Antifungal Edible Coatings for Fresh Citrus Fruit: A Review

    Directory of Open Access Journals (Sweden)

    Lluís Palou

    2015-12-01

    Full Text Available According to their origin, major postharvest losses of citrus fruit are caused by weight loss, fungal diseases, physiological disorders, and quarantine pests. Cold storage and postharvest treatments with conventional chemical fungicides, synthetic waxes, or combinations of them are commonly used to minimize postharvest losses. However, the repeated application of these treatments has led to important problems such as health and environmental issues associated with fungicide residues or waxes containing ammoniacal compounds, or the proliferation of resistant pathogenic fungal strains. There is, therefore, an increasing need to find non-polluting alternatives to be used as part of integrated disease management (IDM programs for preservation of fresh citrus fruit. Among them, the development of novel natural edible films and coatings with antimicrobial properties is a technological challenge for the industry and a very active research field worldwide. Chitosan and other edible coatings formulated by adding antifungal agents to composite emulsions based on polysaccharides or proteins and lipids are reviewed in this article. The most important antifungal ingredients are selected for their ability to control major citrus postharvest diseases like green and blue molds, caused by Penicillium digitatum and Penicillium italicum, respectively, and include low-toxicity or natural chemicals such as food additives, generally recognized as safe (GRAS compounds, plant extracts, or essential oils, and biological control agents such as some antagonistic strains of yeasts or bacteria.

  1. A bench scale study of a one-step dissolution process for treating contaminated fiberglass filters

    International Nuclear Information System (INIS)

    High efficiency mist eliminators (HEME) and high efficiency particulate air filters (HEPA) made of High fiberglass will be used at the Savannah River Site (SRS) to remove particulate matter from offgases generated during melter feed preparation and vitrification of high-level radioactive waste (HLW) at the Defense Waste Processing Facility (DWPF). These filters will be contaminated with high-level, radioactive species and also with various high-boiling organic compounds. For this reason, a process was developed at the Savannah River Technology Center (SRTC) that will dissolve the spent filters so that the residues may be recycled to the HLW tanks for eventual vitrification. This process involves boiling the filters sequentially in NaOH, HN03 and NaOH, while contained in a stainless steal wire mesh frame assembly. The objective of this communication is to present some of the original preliminary work done by Ritter on the simple one-step dissolution process. The results from six bench-scale experiments are reported for the dissolution of an organically-fouled sample of HEME obtained from the Integrated DWPF Melter (IDMS) offgas filtration system. The preliminary effects of filter packing density, air sparging versus rotating basket agitation, fouling, and adding Triton X-405 as a dispersing agent are reported

    2013-04-01

    Full Text Available ‘Islanding’ is a term, which refers to the situation when the Distributed generator (DG continues to power the consumer-end even when the electrical power from the electric utility is no longerpresent. Islanding phenomenon occurs after the certain part of the utility grid gets disconnected from a large number of inter-connected PVs. It leads to troubles in voltage and frequency control and powerquality issues. Therefore there is a need for appropriate anti-islanding measures for grid-connected PV systems. There are two ways to defeat the islanding phenomenon, by reactor insertion method on utility side and capacitor insertion method on PV side. Some of the Islanding detection methods (IDMs are broadly classifies as Active, Passive and Utility based. Active mode of detection includes impedance measurement, slip mode frequency shift and frequency bias. Passive methods contain over/under voltage and frequency and harmonics detection. Utility-based methods consist of manual disconnection, SCADA, impedance insertion.

    Full Text Available Nanofer zerovalent iron (nanofer ZVI is a new and innovative nanomaterial capable of removing organic as well as inorganic contaminants in water. It displays a decrease in agglomeration, when it is coated with tetraethyl orthosilicate (TEOS. TEOS imparts an increase in reactivity and stability to nanofer ZVI. Characteristics of nanofer ZVI were determined using scanning electron microscope/electron dispersive spectroscope (SEM/EDS, transmission electron microscope (TEM, and X-ray diffraction (XRD. Nanoparticle size varied from 20 to 100 nm and its surface area was in the range of 25–30 m2g−1. The present study examined its structure before and after kinetic experiments. Kinetic experiments indicated that adsorption of heavy metals [Pb (II, Cd (II, and Cu (II] and TCE is very rapid during the initial step which is followed by a much slower second step. Removal rates of 99.7% for Pb (II, 99.2% for Cd (II, 99.9% for Cu (II, and 99.9% for TCE were achieved in less than 180 minutes. Lagergren models (LM, liquid film diffusion model (LFDM, and interparticle diffusion model (IDM were used to understand the removal mechanism associated with nanofer ZVI. In this study, interactions of nanofer ZVI with individual metals as well as TCE are examined.

  4. Non-destructive assay system for uranium and plutonium in reprocessing input solutions. Hybrid K-edge/XRF Densitometer. JASPAS JC-11 final report

    International Nuclear Information System (INIS)

    As a part of JASPAS programme, a non-radioactive assay system for the accountability of uranium and plutonium in input dissolver solutions of a spent fuel reprocessing plant, called Hybrid K-edge/XRF Densitometer, has been developed at the Tokai Reprocessing plant (TRP) since 1991. The instrument is the one of the hybrid type combined K-edge densitometry (KED) and X-ray fluorescence (XRF) analysis. The KED is used to determine the uranium concentration and the XRF is used to determine the U/Pu ratio. These results give the plutonium concentration in consequence. It is considered that the instrument has the capability of timely on-site verification for input accountancy. The instrument had been installed in the analytical hot cell at the TRP and the experiments comparing with Isotope Dilution Mass Spectrometry (IDMS) method have been carried out. As the results of measurements for the actual input solutions in the acceptance and performance tests, it was typically confirmed that the precision for determining uranium concentration by the KED was within 0.2%, whereas the XRF for plutonium performed within 0.7%. This final report summarizes the design information and performance data so as to end the JASPAS programme. (author)

  5. Determination of GHB and its precursors (GBL and 1,4-BD) in dietary supplements through the synthesis of their isotopologues and analysis by GC-MS method.

    Gamma-hydroxybutyric acid (GHB) and its "pro-drugs", gamma-butyrolactone (GBL) and 1,4 butanediol (1,4-BD), are drugs of abuse with depressant effects on the central nervous system. Many analytical methods have been proposed for the quantitative determination of these compounds mainly in biological matrices but only few have been addressed to dietary supplements and foods. Facile synthesis of the GBL and 1,4-BD isotopologues are available by "one pot" Ru-catalyzed homogeneous deuteration of dicarboxylic acids. In this work we propose a new method for determination of GHB, GBL and 1,4-BD in commercially available dietary supplements, based on isotope dilution mass spectrometry (ID-MS). The procedure involves a simple extraction of sample with acidic acetonitrile and direct analysis by GC-ID-MS method without any purification or derivatization. Indeed, the proposed method takes advantage of the complete conversion of GHB (free acid or its salts) to GBL, allowing the quantification of GHB and its pro-drugs. Five levels for each calibration curve have been prepared by diluting working solutions of the analytes to obtain concentrations ranging from 1 to 20mg/mL. The validation procedures have shown an accuracy between 88% and 99% and a precision between 7.3% and 2.9% of each analyte in the sample matrix. Positive ions chemical ionization (PICI) have been employed to preserve the information on molecular ions and to improve specificity and sensitivity of quantitative determination.

  6. Criticism of generally accepted fundamentals and methodologies of traffic and transportation theory: A brief review

    Science.gov (United States)

    Kerner, Boris S.

    2013-11-01

    It is explained why the set of the fundamental empirical features of traffic breakdown (a transition from free flow to congested traffic) should be the empirical basis for any traffic and transportation theory that can be reliably used for control and optimization in traffic networks. It is shown that the generally accepted fundamentals and methodologies of the traffic and transportation theory are not consistent with the set of the fundamental empirical features of traffic breakdown at a highway bottleneck. To these fundamentals and methodologies of the traffic and transportation theory belong (i) Lighthill-Whitham-Richards (LWR) theory, (ii) the General Motors (GM) model class (for example, Herman, Gazis et al. GM model, Gipps’s model, Payne’s model, Newell’s optimal velocity (OV) model, Wiedemann’s model, Bando et al. OV model, Treiber’s IDM, Krauß’s model), (iii) the understanding of highway capacity as a particular (fixed or stochastic) value, and (iv) principles for traffic and transportation network optimization and control (for example, Wardrop’s user equilibrium (UE) and system optimum (SO) principles). Alternatively to these generally accepted fundamentals and methodologies of the traffic and transportation theory, we discuss the three-phase traffic theory as the basis for traffic flow modeling as well as briefly consider the network breakdown minimization (BM) principle for the optimization of traffic and transportation networks with road bottlenecks.

When subject to external excitation, a building may suffer a certain degree of damages, and its residual capacity to resist external excitation cannot be evaluated. In this research, dynamic digital image correlation method combined with parameter evaluation available in system identification is used to evaluate the structural capacity to resist external excitation. The results reveal possible building latent safety problems so that timely structural reinforcement or dismantling of the building can be initiated to alleviate further damages. The results of experiments using the proposed method conform to the results obtained using the conventional method, but this method is more convenient and rapid than the latter in the subsequent procedure of data processing. If only the frequency change is used, the damages suffered by the building can be detected, but the damage location is not revealed. The interstory drift mode shape (IDMS based on the characteristic of story drift has higher sensitivity than the approximate story damage index (ADSI method based on modal frequency and vibration type; however, both indices can be used to determine the degree and location of building damages.

    As a part of JASPAS programme, a non-radioactive assay system for the accountability of uranium and plutonium in input dissolver solutions of a spent fuel reprocessing plant, called Hybrid K-edge/XRF Densitometer, has been developed at the Tokai Reprocessing plant (TRP) since 1991. The instrument is the one of the hybrid type combined K-edge densitometry (KED) and X-ray fluorescence (XRF) analysis. The KED is used to determine the uranium concentration and the XRF is used to determine the U/Pu ratio. These results give the plutonium concentration in consequence. It is considered that the instrument has the capability of timely on-site verification for input accountancy. The instrument had been installed in the analytical hot cell at the TRP and the experiments comparing with Isotope Dilution Mass Spectrometry (IDMS) method have been carried out. As the results of measurements for the actual input solutions in the acceptance and performance tests, it was typically confirmed that the precision for determining uranium concentration by the KED was within 0.2%, whereas the XRF for plutonium performed within 0.7%. This final report summarizes the design information and performance data so as to end the JASPAS programme. (author)

  9. Fit for purpose: do we have the right tools to sustain NTD elimination?

    2015-01-01

    Priorities for NTD control programmes will shift over the next 10-20 years as the elimination phase reaches the ‘end game’ for some NTDs, and the recognition that the control of other NTDs is much more problematic. The current goal of scaling up programmes based on preventive chemotherapy (PCT) will alter to sustaining NTD prevention, through sensitive surveillance and rapid response to resurgence. A new suite of tools and approaches will be required for both PCT and Intensive Disease Management (IDM) diseases in this timeframe to enable disease endemic countries to: 1. Sensitively and sustainably survey NTD transmission and prevalence in order to identify and respond quickly to resurgence. 2. Set relevant control targets based not only on epidemiological indicators but also entomological and ecological metrics and use decision support technology to help meet those targets. 3. Implement verified and cost-effective tools to prevent transmission throughout the elimination phase. Liverpool School of Tropical Medicine (LSTM) and partners propose to evaluate and implement existing tools from other disease systems as well as new tools in the pipeline in order to support endemic country ownership in NTD decision-making during the elimination phase and beyond.

    A feasibility study for producing a matrix reference material for selected polycyclic aromatic hydrocarbons (PAHs) in baby food is reported. A commercially available baby food, containing carrots, potatoes, tomato, white beans and meat, was spiked with the so-called 15 + 1 PAHs included in the PAHs priority list for food of the EU, at a mass fraction level of 1 μg/kg. The contaminated baby food was further processed by autoclaving, freezing or freeze drying. The homogeneity of the three materials (bottle-to-bottle variation) and their short-term (4 weeks) and long-term (18 months) stability at different temperatures were assessed. To this end, an analytical method based on a solid-liquid extraction followed by cleaning up with gel permeation chromatography (GPC) and solid phase extraction (SPE) and GC-IDMS determination, was validated in-house. It could be demonstrated that the procedure fulfilled the demands for application to the homogeneity and isochronous stability studies for the candidate reference materials targeted here. All three materials proved to be sufficiently homogeneous for the intended use. Measurements on the autoclaved material provided the most promising results in terms of envisaged shelf life, although freeze drying was also found to be a suitable processing technique for most of the investigated PAHs. These results are an important step towards the development of a matrix reference material for PAHs in a processed food matrix in a presentation very similar to routine samples.

    Due to the uncertainty of both ground motions and structural capacity,it is necessary to consider the seismic performance of viaduct structures using the probabilistic method.The risk is quantified by a procedure on the basis of a numerical determination of the fragility curves.A group of ground motions,Large Magnitude-Short Distance Bin (LMSR-N),selected specially due to its response spectra,is accorded well with the corresponding spectra of the Chinese code for seismic design.The characteristic values of the curvature ductility factors for the serviceability and the damage control limit states are obtained,and two equations for estimating the characteristic values of the curvature ductility factors are developed through regression analysis.Then,the serviceability and damage control limit states were proposed.Three damage states were constituted according the results of the experiment by Pacific Earthquake Engineering Research (PEER) Center.The analytical fragility curves were obtained specifically,using both Capacity Spectrum Method (CSM) (non-linear static) analysis and Ineremental Dynamic Method (IDM) (non-linear dynamic) analysis,respectively,in this paper.The structural fragility curves developed by CSM method can help make the structural analysis simple and quick,avoiding the implementation of the dynamic response history analysis (RHA).Although the dynamic RHA requires a lot of complicated analysis for the structure,the results from RHA are reliable and accurate.Fragility curves are powerful tools for use in performance-based seismic bridge design.

  12. Behavior of mercury in the formic acid vent condenser. Interim report

    (This report relates to the Defense Waste Processing Facility.) The concentrations of mercury at the FAFC inlet and exit were measured during the BL1 and PX6 runs of the Integrated DWPF Melter System (IDMS) with the HEME bypassed and without the ammonia scrubber. The results show that mercury concentrations of approximately 2.6-12.7 (mean = 6.2) times saturation occur at the FAFC exit. The concentration of mercury at the SRAT condenser exit was found to be 10 times the saturation value. FAVC exit mercury concentrations of 6.2 times saturation would result in DWPF emitting up to 438 lb/yr of mercury at 100 percent attainments, which is in excess of the permit limit of 175 lb/yr. However, operation of the FAVC with the HEME should reduce the mercury emissions. The addition of the ammonia scrubbers should also reduce the mercury emissions since the nitric acid used to scrub ammonia should also scrub mercury.

    We report systematic measurements of the interfacial Dzyaloshinskii-Moriya interaction (iDMI) by employing Brillouin light scattering in Pt/Co/AlO{sub x} and Ta/Pt/Co/AlO{sub x} structures. By introducing a tantalum buffer layer, the saturation magnetization and the interfacial perpendicular magnetic anisotropy are significantly improved due to the better interface between heavy metal and ferromagnetic layer. From the frequency shift between Stokes- and anti-Stokes spin-waves, we successively obtain considerably larger iDM energy densities (D{sub max} = 1.65 ± 0.13 mJ/m{sup 2} at t{sub Co} = 1.35 nm) upon adding the Ta buffer layer, despite the nominally identical interface materials. Moreover, the energy density shows an inverse proportionality with the Co layer thickness, which is the critical clue that the observed iDMI is indeed originating from the interface between the Pt and Co layers.

    Full Text Available Ammonium (NH4+ is the most common N-source for yeast fermentations, and N-limitation is frequently applied to reduce growth and increase product yields. While there is significant molecular knowledge on NH4+ transport and assimilation, there have been few attempts to measure the in vivo concentration of this metabolite. In this article, we present a sensitive and accurate analytical method to quantify the in vivo intracellular ammonium concentration in Saccharomyces cerevisiae based on standard rapid sampling and metabolomics techniques. The method validation experiments required the development of a proper sample processing protocol to minimize ammonium production/consumption during biomass extraction by assessing the impact of amino acid degradation—an element that is often overlooked. The resulting cold chloroform metabolite extraction method, together with quantification using ultra high performance liquid chromatography-isotope dilution mass spectrometry (UHPLC-IDMS, was not only more sensitive than most of the existing methods but also more accurate than methods that use electrodes, enzymatic reactions, or boiling water or boiling ethanol biomass extraction because it minimized ammonium consumption/production during sampling processing and interference from other metabolites in the quantification of intracellular ammonium. Finally, our validation experiments showed that other metabolites such as pyruvate or 2-oxoglutarate (αKG need to be extracted with cold chloroform to avoid measurements being biased by the degradation of other metabolites (e.g., amino acids.

    Credential-based authorization offers interesting advantages for ubiquitous scenarios involving limited devices such as sensors and personal mobile equipment: the verification can be done locally; it offers a more reduced computational cost than its competitors for issuing, storing, and verification; and it naturally supports rights delegation. The main drawback is the revocation of rights. Revocation requires handling potentially large revocation lists, or using protocols to check the revocation status, bringing extra communication costs not acceptable for sensors and other limited devices. Moreover, the effective revocation consent—considered as a privacy rule in sensitive scenarios—has not been fully addressed. This paper proposes an event-based mechanism empowering a new concept, the sleepyhead credentials, which allows to substitute time constraints and explicit revocation by activating and deactivating authorization rights according to events. Our approach is to integrate this concept in IdM systems in a hybrid model supporting delegation, which can be an interesting alternative for scenarios where revocation of consent and user privacy are critical. The delegation includes a SAML compliant protocol, which we have validated through a proof-of-concept implementation. This article also explains the mathematical model describing the event-based model and offers estimations of the overhead introduced by the system. The paper focus on health care scenarios, where we show the flexibility of the proposed event-based user consent revocation mechanism. PMID:22778634

    Use of plant products for the management of phytopathogenic fungi is fast becoming an important component of Integrated Disease Management (I.D.M.) programme. The natural plant products are bio-degradable and thus eco-friendly, are catching the attention of the scientist worldwide. Such products from higher plants are relatively broad spectrum, bio-efficacious, economical and environmentally safe. Among these essential oils from higher plants because of their greater inhibitory action are being explored preferably worldwide. In this context, a study was undertaken to explore the effect of volatile oil from Eucalyptus citriodora against Alternaria triticina. The radial growth, dry weight and spore germination of pathogen were drastically reduced in response to the different concentrations of volatile oil. A complete inhibition of radial growth, dry weight and spore germination were observed at 1500, 1000 and 100 ppm, respectively. In contrast, similar complete inhibition of test pathogen was observed at very high concentration (6500, 6500 and 1000 ppm) of mancozeb--a commercially available synthetic fungicide. Based on these observations, it was therefore concluded that eucalypt volatile oil has potential to suppress the phytopathogenic fungi. PMID:17390838

    Previous work has outlined that certain mammographic appearances feature more prominently in reader's false negative responses on a self-assessment scheme. Bi-annually 600 breast-screening film-readers complete at least one round of the Personal Performance in Mammographic Screening (PERFORMS) self-assessment scheme in the UK. The main occupational groups in UK Breast Screening can be categorised thus, Radiologist, Technologists and Symptomatics. Previous work has shown that these groups can vary in their reading 'style' and accuracy on self-assessed cases. These groups could be said to contain individuals each with (arguably) pronounced differences in their real life reading experience, symptomatic readers routinely read a large number of cases with abnormal appearances and Technologists (specially trained to read films) do not have the same medical background as breast-screening Radiologists. We aimed to examine overall (national) and group (occupational) differences in terms of ROC analysis on those mammographic cases with different mammographic appearance (feature type). Several main feature types were identified namely; Well Defined Mass (WDM), Ill Defined Mass (IDM), Spiculate Mass (SPIC), Architectural Distortions (AD), Asymmetry (ASYM) and Calcification (CALC). Results are discussed in light of differences in real-life practice for each of the occupational groups and how this may impact on accuracy over certain mammographic appearances.

    Full Text Available Cork oak (Quercus suber L. and holm oak (Quercus rotundifolia ecosystems are characteristic of Mediterranean forestry in Portugal. Even though cork is the most valuable product, these ecosystems provide multiple products and services. Assessing trade-offs between multiple goals is thus critical for the effectiveness of oak ecosystem management planning. This paper focuses on the development of a decision support system for oak ecosystems’ scenario analysis including multiple criteria. It includes an innovative decision support systems (DSS functionality to assess trade-offs between the criteria that may support negotiation and consensus building between decision-makers and forest stakeholders. Specifically, a module that encapsulates the Feasible Goals Method/Interactive Decision Maps (FGM/IDM technique is developed for interactive visualization of the Pareto frontier. The Pareto frontier illustrates the degree to which improving one particular criterion requires accepting sacrifices in the achievements of others. It thus provides information about trade-offs between competing decision-makers’ preferences. Results are discussed for a large-scale application encompassing over 1 million ha of cork and holm oak forest ecosystems in Southern Portugal. This study demonstrates the potential of the new DSS functionality to enhance multi-objective forest planning, namely by facilitating participation by stakeholders and providing transparency to the decision-making processes.

    Models of dark matter with ~ GeV scale force mediators provide attractive explanations of many high energy anomalies, including PAMELA, ATIC, and the WMAP haze. At the same time, by exploiting the ~ MeV scale excited states that are automatically present in such theories, these models naturally explain the DAMA/LIBRA and INTEGRAL signals through the inelastic dark matter (iDM) and exciting dark matter (XDM) scenarios, respectively. Interestingly, with only weak kinetic mixing to hypercharge to mediate decays, the lifetime of excited states with delta < 2 m_e is longer than the age of the universe. The relic abundance of these excited states depends on the temperature of kinetic decoupling, but can be appreciable. There could easily be other mechanisms for rapid decay, but the consequences of such long-lived states are intriguing. We find that CDMS constrains the relic population of ~100 keV states to be < 10^{-2}, for a 1 TeV WIMP with sigma_n = 10^{-40} cm^2. Upcoming searches at CDMS, as well as xenon...

    For the past decade, operations and research projects that support a major portion of NASA's overall mission have experienced a dramatic increase in the volume of generated data and resultant information that is unparalleled in the history of the agency. The effect of such an increase is that most of the science and engineering disciplines are undergoing an information glut, which has occurred, not only because of the amount, but also because of the type of data being collected. This information glut is growing exponentially and is expected to grow for the foreseeable future. Consequently, it is becoming physically and intellectually impossible to identify, access, modify, and analyze the most suitable information. Thus, the dilemma arises that the amount and complexity of information has exceeded and will continue to exceed, using present information systems, the ability of all the scientists and engineers to understand and take advantage of this information. As a result of this information problem, NASA has initiated the Intelligent Data Management (IDM) project to design and develop Advanced Information Management Systems (AIMS). The first effort of the Project was the prototyping of an Intelligent User Interface (IUI) to an operational scientific database using expert systems, natural language processing, and graphics technologies. An overview of the IUI formulation and development for the second phase is presented.
