  1. ... stella tenax... Variations on Vanités by Brice Pauset

    Directory of Open Access Journals (Sweden)

    Laurent Feneyrou

    2015-09-01

    Full Text Available Between 2000 and 2002, Brice Pauset composed Vanités, twenty-five fragments (for echo soprano, principal haute-contre, principal harpsichord, two echo harpsichords, theorbo, two violins, viola, cello, and contrabass that fall within the secular history of melancholy and its artistic representation. The work models after Leçons de ténèbres by Marc- Antoine Charpentier and refers to still lifes by Willem Kalf. In addition, it boasts a number of musical languages, concepts, and genres organized in cycles borrowed from other historical periods, including canons, choirs, and passacaglia. This article aims to study the libretto, its montage, its significance, and its related melancholic representation, as well as the metric organization of the work and its complex intercombinations – inspired by the Magic Square of Melancholia I and the name of its author, Albrecht Dürer. The result is a new rhetoric, which requires formal analysis, as well as an analysis of the expressive, symbolic, and metaphoric dimensions whose musical signs are holders.

  2. Inventario de la entomofauna asociada al cultivo de pitahaya amarilla (Selenicereus megalanthus Haw. en Briceño (Boyacá

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Boyacá es uno de los departamentos con mayor producción de pitahaya amarilla en el país. Los estudios realizados sobre este cultivo son muy pocos, y el conocimiento de la entomofauna asociada a él es un punto de partida para realizar nuevas investigaciones que permitan identificar la entomofauna asociada a este cultivo en el municipio de Briceño (Boyacá. El desarrollo de esta investigación se llevó a cabo en plantaciones de pitahaya en tres fincas del municipio de Briceño (Boyacá. Se realizaron muestreos empleando métodos activos, como captura manual directa, uso de red y aspirador entomológico, y métodos pasivos, como trampas con atrayentes y trampas  de caída. Los insectos colectados se sometieron a cámara letal y luego se montaron en alfileres para su posterior identificación con ayuda del estereoscopio y claves taxonómicas. En las tres fincas se identificaron un total de 9 órdenes y 58 familias, y los órdenes Hymenóptera y Díptera se reportaron con la mayor cantidad de individuos benéficos. En la finca San Pablo se observó la mayor cantidad de insectos; también fue la única en donde se evidenció la presencia de la plaga más limitante para este cultivo, que es Dasiops saltans (mosca del botón floral. La cantidad de familias presentes en los muestreos se ve influenciada más por el manejo agronómico implementado en cada finca que por las variables climatológicas, como temperatura, humedad relativa y precipitación.

  19. Correlation between blister skin thickness, the maximum in the damage-energy distribution, and projected ranges of He+ ions in metals: Nb

    International Nuclear Information System (INIS)

    Kaminsky, M.; Das, S.K.; Fenske, G.

    1975-01-01

    The skin thicknesses of blisters formed on niobium by helium-ion irradiation at room temperature for energies from 100 to 1500 keV have been measured. The projected ranges of helium ions in Nb for this energy range were calculated using either Brice's formalism or the one given by Schiott. For the damage-energy distribution Brice's formalism was used. The measured skin-thickness values corrleate more closely with the maxima in the projected-range probability distributions than with the maxima in the damage-energy distributions. The results are consistent with our model for blister formation and rupture proposed earlier

  12. Identifying sources of groundwater nitrate contamination in a large alluvial groundwater basin with highly diversified intensive agricultural production

    Science.gov (United States)

    Lockhart, K. M.; King, A. M.; Harter, T.

    2013-08-01

    Groundwater quality is a concern in alluvial aquifers underlying agricultural areas worldwide. Nitrate from land applied fertilizers or from animal waste can leach to groundwater and contaminate drinking water resources. The San Joaquin Valley, California, is an example of an agricultural landscape with a large diversity of field, vegetable, tree, nut, and citrus crops, but also confined animal feeding operations (CAFOs, here mostly dairies) that generate, store, and land apply large amounts of liquid manure. As in other such regions around the world, the rural population in the San Joaquin Valley relies almost exclusively on shallow domestic wells (≤ 150 m deep), of which many have been affected by nitrate. Variability in crops, soil type, and depth to groundwater contribute to large variability in nitrate occurrence across the underlying aquifer system. The role of these factors in controlling groundwater nitrate contamination levels is examined. Two hundred domestic wells were sampled in two sub-regions of the San Joaquin Valley, Stanislaus and Merced (Stan/Mer) and Tulare and Kings (Tul/Kings) Counties. Forty six percent of well water samples in Tul/Kings and 42% of well water samples in Stan/Mer exceeded the MCL for nitrate (10 mg/L NO3-N). For statistical analysis of nitrate contamination, 78 crop and landuse types were considered by grouping them into ten categories (CAFO, citrus, deciduous fruits and nuts, field crops, forage, native, pasture, truck crops, urban, and vineyards). Vadose zone thickness, soil type, well construction information, well proximity to dairies, and dominant landuse near the well were considered. In the Stan/Mer area, elevated nitrate levels in domestic wells most strongly correlate with the combination of very shallow (≤ 21 m) water table and the presence of either CAFO derived animal waste applications or deciduous fruit and nut crops (synthetic fertilizer applications). In Tulare County, statistical data indicate that elevated

  15. Correlation between blister skin thickness, the maximum in the damage-energy distribution, and the projected ranges of He+ ions in metals

    International Nuclear Information System (INIS)

    Das, S.K.; Kaminsky, M.; Fenske, G.

    1976-01-01

    The skin thickness of blisters formed on aluminium by helium-ion irradiation at room temperature for energies from 100 to 1000 keV have been measured. The projected ranges of helium ions in Al for this energy range were calculated using either Brice's formalism (Brice, D.K., 1972, Phys. Rev., vol. A6, 1791) or the one given by Schioett (Schioett, H.E., 1966, K. Danske Vidensk.Selsk., Mat.-Fys. Meddr., vol.35, No.9). For the damage-energy distribution Brice's formalism was used. The measured skin thickness values are smaller than the calculated values of the maxima in the projected range distributions over the entire energy range studied. These results on the ductile metal aluminium are contrasted with the results on relatively brittle refractory metals V and Nb where the measured skin thickness values correlate more closely with the maxima in the projected range probability distributions than with the maxima in the damage-energy distributions. Processes affecting the blister skin fracture and the skin thickness are discussed. (author)

    Calcium silicate hydrates are compounds of SiO2 – CaO – H2O system. These materials are used to make lime-sand bricks concretes, or “cellular concretes”, lime-flint brices and as fillers in rubber, paint and plastic products industries, among others. Undoubtedly, the tobermoritas is the most interesting group given its important role in concrete hydration: hydrated calcium silicate (C – S- H) is the main concrete hydration product and its primary bounding phase.

    Anne Brice, recipient of the 2014 Cyril Barnard Memorial Prize, reflects on the themes of names and skills of the health library and information professions. She questions whether service users share the same concerns of librarians that this nomenclature is too narrow and too closely associated with the buildings that provide its name.

(Image : Maximilien Brice/ CERN) The activities under way in the framework of the CERN Neutrino Platform are multiple and restless. Along with the refurbishment of ICARUS, another project is making great strides towards its completion: WA105. In spite of the not-so-expressive name, the technology being tested in this prototype is unprecedented. WA105, presently at an advanced state of assembly at CERN, is a 3x1x1-metre, 25-tonne “dual-phase” liquid argon time projection chamber (DLAr-TPC) demonstrator. It has been conceived in the quest to solve the technological problems related to the next generation of neutrino detectors, whose dimensions need to be gigantic in order to thoroughly study the phenomenon of neutrino oscillations.

    Full Text Available The aim of this paper is to determine the ways in which the culture one lives in is conceptualized through the understanding of modern football. The focus is on the overlapping and negotiation of identity politics determined by the local cultural context, while also taking note of the increasing globalization of the sport itself. Special attention will be given to the discourse on safety, it being one of the key narratives about modern football. By following the media narratives on the topic, especially those concerning the murder of the French supporter Brice Taton in Belgrade in 2009, I will attempt to point out the images which dominate the conceptualization of contemporary domestic football, and through this, the period of transition which Serbia is currently going through.

  14. Ion-driven permeation of deuterium through tungsten under simultaneous helium and deuterium irradiation

    2011-01-01

    Ion-driven permeation of D through tungsten under simultaneous irradiation with He-D was measured as a function of temperature, flux, and energy. He reduced the permeation flux with the reduction increasing with decreasing temperature. The reduction in permeation flux followed a linear dependence to the incident flux at T > 1000 K, but shifted to a square root dependence at T < 1000 K. The results were interpreted as shifts from diffusion limited to recombination limited H transport according to Doyle and Brice's theory. Arrhenius functions of front diffusivity and recombination coefficients were derived and used to calculate the transport parameter W. The effect of He can be interpreted as changes to the front diffusivity that approaches H diffusion behavior in the absence of traps. The reduction in total concentration results in a shallower concentration gradient that can describe the observed decrease in permeation.

    Hydrothermal zircon grains have trace element characteristics such as low Th/U, high U, and high rare earth element (REE) concentrations that distinguish them from magmatic, metamorphic, and altered zircon grains, but it is unclear whether these characteristics result from distinctive fluid compositions or zircon/fluid fractionation effects. New experiments aimed at measuring zircon/fluid trace element partition coefficients Dz/f involved recrystallizing natural Mud Tank zircon with low trace element concentrations in the presence of H2O, 1 m NaOH, or 1 m HCl doped with ∼1000 ppm of rare earth elements (REE), Y, U and Th and ∼500 ppm of Li, B, P, Nb, Ba, Hf, and Ta. Experiments were run for 168 h at 1.5 GPa, 800-1000 °C, and fO2 = NNO in a piston cylinder apparatus using the double capsule method. LA-ICP-MS analysis shows that run product zircon crystals have much higher trace element concentrations than in Mud Tank zircon starting material. Dz/f values were estimated from run product zircon analyses and bulk composition using mass balance. Most elements behave incompatibly, with median Dz/f being highest for Hf = 8 and lowest for B = 0.02. Addition of NaOH or HCl had little influence on Dz/f values. Dz/f for LREE are anomalously high, likely due to contamination of run product zircon with quenched solutes enriched in incompatible elements, so DLREE were estimated using lattice strain theory. Brice curves for +3 ions yield zircon/fluid DLu/DLa of ∼800-5000. A Brice curve fit to +4 ions yielded DCe4+ values. Estimated concentrations of Ce3+ and Ce4+ show that the average Ce4+/Ce3+ in zircon of 27 is much higher than in fluid of 0.02. Th and U show little fractionation, with median DTh/DU = 0.7, indicating that the low Th/U in natural hydrothermal zircon is inherited from the fluid. Natural fluid compositions estimated from measured Dz/f and published compositions of hydrothermal zircon grains from aplite and eclogite reflect the mineralogy of the host rock, e

  1. Wave propagation in the magnetosphere of Jupiter

    Liemohn, H. B.

    1972-01-01

    A systematic procedure is developed for identifying the spatial regimes of various modes of wave propagation in the Jupiter magnetosphere that may be encountered by flyby missions. The Clemmow-Mullaly-Allis (CMA) diagram of plasma physics is utilized to identify the frequency regimes in which different modes of propagation occur in the magnetoplasma. The Gledhill model and the Ioannidis and Brice model of the magnetoplasma are summarized, and configuration-space CMA diagrams are constructed for each model for frequencies from 10 Hz to 1 MHz. The distinctive propagation features, the radio noise regimes, and the wave-particle interactions are discussed. It is concluded that the concentration of plasma in the equatorial plane makes this region of vital importance for radio observations with flyby missions. Local radio noise around the electron cyclotron frequency will probably differ appreciably from its terrestrial counterpart due to the lack of field-line guidance. Hydromagnetic wave properties at frequencies near the ion cyclotron frequency and below will probably be similar to the terrestrial case.

    New results presented by the LHCb collaboration on the decay of particles containing a “charm” quark delve deeper into the mystery of matter-antimatter asymmetry.   A view of the LHCb experimental cavern. (Photo: Maximilien Brice/CERN) One of the biggest challenges in physics is to understand why everything we see in our universe seems to be formed only of matter, whereas the Big Bang should have created equal amounts of matter and antimatter. CERN’s LHCb experiment is one of the best hopes for physicists looking to solve this longstanding mystery. At the VIII International Workshop on Charm Physics, which took place in Bologna earlier this month, the LHCb Collaboration presented the most precise measurement to date of a phenomenon called Charge-Parity (CP) violation among particles that contain a charm quark. CP symmetry states that laws of physics are the same if a particle is interchanged with its anti-particle (the “C” part) and if its spatia...

    Transmission electron microscopy has been used to study the depth distribution of bubbles (or voids) and dislocation damage in nickel irradiated at 500 0 C with 20- and 500-keV 4 He + ions to total doses ranging from 2.9 x 10 15 to 5 x 10 17 ions/cm 2 . The size, number density, and volume fraction of bubbles (or voids) were measured from micrographs taken from samples sectioned parallel to the surface normal. The results for 500-keV irradiation show that the peaks in the depth distribution of number density and of volume fraction (i.e., swelling) of bubbles (or voids) are approx. 20% deeper than the calculated projected range distribution. However, for 20-keV irradiation the peak in the swellig occurs at a depth which is about a factor of two larger than the peak in the distributions of projected range and the energy deposited into damage as calculated according to Brice. The peak positions are nearly independent of the total doses used in these studies. The implications of these results for the blistering mechanisms are discussed

    Prior reports suggest that dreaming during anaesthesia is dependent on recovery time. Dreaming during sedation may impact patient satisfaction. The current study explores the incidence and content of dreaming during short-term sedation with sevoflurane or propofol and investigates whether dreaming is affected by recovery time. A total of 200 women undergoing first trimester abortion (American Society of Anesthesiologists physical status I) participated in the study. Patients were randomly assigned to receive either sevoflurane or propofol for short-term sedation. Patients were interviewed upon emergence with the modified Brice questionnaire. The results showed the incidence of dreaming was significantly different between anaesthesia groups with 60% (60/100) of the sevoflurane group and 33% (33/100) of the propofol group (P=0.000). However, recovery time did not significantly differ between groups. In the sevoflurane group, a greater number of dreamers could not recall what they had dreamed about (P=0.02) and more patients reported dreams that had no sound (P=0.03) or movement (P=0.001) compared with dreamers in the propofol group. Most participants reported dreams with positive emotional content and this did not significantly differ between groups. Anaesthesia administered had no effect on patient satisfaction. The results suggest that the incidence of dreaming was not affected by recovery time. Patient satisfaction was not influenced by choice of sedative and/or by the occurrence of dreaming during sevoflurane or propofol short-term sedation.

    Previous reports suggest that sex differences may exist in dreaming under anesthesia, but their results were inconclusive. The current study explored sex differences in the incidence and content of dreams during short propofol sedation for upper gastrointestinal endoscopy and investigated whether sex differences or dream content affect patient satisfaction with sedation. A total of 200 patients (100 men and 100 women) undergoing upper gastrointestinal endoscopy participated in this study. Patients were interviewed with the modified Brice questionnaire about the incidence and the content of dreams, and satisfaction with sedation was assessed. The results showed that the incidence of dreaming was significantly higher in men (31%) than in women (17%) (P=0.02), but recovery time was similar. In men, 45% (14/31) of dreamers reported positive emotional content and only 6% (2/31) reported negative emotional content. In contrast, in women, 18% (3/17) reported positive and 29% (5/17) reported negative content (P=0.04). Men reported dreams that were more vivid, meaningful, familiar, and memorable (PDreamer satisfaction with sedation was not influenced by sex or dream content.

    and Chris Langdon, Brice Loose, Dwight Gledhill, Diana Hsueh, Derek Manzello, Ian Enochs, Ryan Moyer We present net ecosystem productivity (nep) and net ecosystem calcification (nec) in coral and seagrass ecosystems using the boundary layer gradient flux technique (CROSS). Coastal anthropogenic inputs and changes in global ocean chemistry in response to rising levels of atmospheric carbon dioxide has emerged in recent years as a topic of considerable concern. Coral reefs are particularly vulnerable from eroded environmental conditions including ocean acidification and water pollution. The Atlantic Ocean Acidification Testbed (AOAT) project monitors metabolism to ascertain the continuing health of coral reef ecosystems. The CROSS boundary layer nep/nec approach is one component of this diagnostic program. Certification of CROSS as an operational monitoring tool is underway in the AOAT. CROSS inspects a benthic community and measures productivity/respiration and calcification/dissolution over an area of 10 square meters. Being a boundary layer tool, advection and complex mesoscale flows are not a factor or concern and CROSS is autonomous and can be used at deep benthic sites. The interrogation area is not enclosed therefore exposed to ambient light, flow, and nutrient levels. CROSS is easy to deploy, unambiguous, and affordable. Repeated measurements have been made from 2011-2012 in reefal systems in La Parguera Puerto Rico and the Florida Keys, USA. Diurnal, seasonal and regional metabolism will be compared and discussed. The ability to accurately probe benthic ecosystems provides a powerful management and research tool to policy makers and researchers.

(Photo: Max Brice/CERN) Extraordinary research needs extraordinary machines: the upgrade project of the LHC, the High-Luminosity LHC (HL-LHC), has the goal of achieving instantaneous luminosities a factor of five larger than the LHC nominal value, and it relies on magnetic fields reaching the level of 12 Tesla. The superconducting niobium-titanium (Nb-Ti) used in the LHC magnets can only bear magnetic fields of up to 9-10 Tesla. Therefore, an alternative solution for the superconducting magnets materials was needed. The key innovative technology to develop superconducting magnets beyond 10 Tesla has been found in the niobium-tin (Nb3Sn)  compound. This compound was actually discovered in 1954, eight years before Nb-Ti, but when the LHC was built, ...

    Full Text Available This pioneering paper is the first to consider the contribution of a new type of urban literature to perceptions and portrayals of the city in the late seventeenth and early eighteenth centuries. It focuses on London and Parisian guidebooks, a genre that has been little studied to date, particularly those of: Germaine Brice, Description nouvelle de ce qui’il ya de plus remarquable dans la Ville de Paris (1684; F. Colsoni, Le Guide de Londres (1693; and Edward Hatton, A New View of London (1708. The article is the first to establish the significance of language primers as source for tourist guidebooks and the prevalence of lexicographers among those producing them. It examines the modern type of non-antiquarian urban guidebook as part of the new urban consumer culture. It also explores the genre’s contribution to a novel form in the writing and understanding of the city in the period focussed on the contemporary and the experiential, rather than the traditional orientation towards the historical and the monumental.

  15. Empress Elisabeth (‘Sisi’ of Austria and Patriotic Fashionism

    2016-10-01

    Full Text Available In this article, Christopher VanDemark explores the intersections between nationalism, fashion, and the royal figure in Hungary between 1857 and the Compromise of 1867. Focusing on aesthetics as a vehicle for feminine power at a critical junction in Hungarian history, VanDemark contextualizes Empress Elisabeth’s role in engendering a revised political schema in the Habsburg sphere. Foreseeing the power of emblematic politics, the young Empress adeptly situated herself between the Hungarians and the Austrians to recast the Hungarian martyrology narrative promulgated after the failed revolution of 1848. Eminent Hungarian newspapers such as the Pesti Napló, Pester Lloyd, and the Vasárnapi Újság form the backbone of this article, as publications such as these facilitated the dissemination of patriotic sentiment while simultaneously exulting the efficacy of symbolic fashions. The topic of study engages with contemporary works on nationalism, which emphasize gender and aesthetics, and contributes to the emerging body of scholarship on important women in Hungarian history. Seminal texts by Catherine Brice, Sara Maza, Abby Zanger, and Lynn Hunt compliment the wider objective of this brief analysis, namely, the notion that the Queen’s body can both enhance and reform monarchical power within a nineteenth-century milieu.

  16. Correlation between blister skin thickness, the maximum in the damage-energy distribution, and projected ranges of helium ions in Nb for the energy range 10 to 1500 keV

    The skin thickness of blisters formed on polycrystalline niobium by 4 He + irradiation at room temperature for energies from 15 to 80 keV have been measured. Similar measurements were conducted for 10 keV 4 He + irradiation at 500 0 C to increase blister exfoliation, and thereby allow examination of a larger number of blister skins. For energies smaller than 100 keV the skin thicknesses are compared with the projected range and the damage-energy distributions constructed from moments interpolated from Winterbon's tabulated values. For energies of 10 and 15 keV the projected ranges and damage-energy distributions have also been computed with a Monte Carlo program. For energies larger than 100 keV the projected ranges of 4 He + in Nb were calculated using either Brice's formalism or the one given by Schiott. The thicknesses for 60 and 80 keV, and those reported earlier for 100 to 1500 keV correlate well with calculated projected ranges. For energies lower than 60 keV the measured thicknesses are larger than the calculated ranges

    Full Text Available Evidence based librarianship, still in its infancy, is slowly gaining interest and momentum. Increased exposure to the evidence based model of practice is allowing information specialists to learn more about what is involved and how its application can affect practice. Events such as the International Conference on Evidence Based Library and Information Practice and publications such as EBLIP help to increase awareness of EBL as well as increase the body of evidence necessary to fully implement such a practice model. Having said that, barriers remain that hinder the application of evidence based librarianship in its most basic form. Brice, Booth and Bexon established six steps involved in the practice of EBL: specify the problem, find evidence to answer the problem, appraise the evidence, apply the results, evaluate the outcome, and redefine the problem. Without a large body of research from which to draw evidence, information professionals are often forced to replace the step of finding the evidence with designing and performing their own research. What this means is that rather than being able to find, appraise, and implement existing research, practitioners are finding themselves in a position where they have to design and carry out original research in order to obtain applicable evidence. Aside from being time consuming and costly, many are not comfortable with research design or data analysis, and they may lack administrative support or the needed resources available to support research. Until the body of evidence is substantially increased, it is essential that original research be encouraged and published. I recently posted a message to the EBLIG electronic mail list requesting EBL success stories. I hoped to hear how people had used evidence to assist in their decision making as well as whether the applied evidence had a positive or negative result once implemented. The response was minimal, save for three people who had carried out

  19. Acceptably aware during general anaesthesia: 'dysanaesthesia'--the uncoupling of perception from sensory inputs.

    Pandit, Jaideep J

    2014-07-01

    This review makes the case for 'dysanaesthesia', a term encompassing states of mind that can arise in the course of anaesthesia during surgery, characterised by an uncoupling of sensation and perceptual experience. This is reflected in a macroscopic, functional model of anaesthetically-relevant consciousness. Patients in this state can be aware of events but in a neutral way, not in pain, sometimes personally dissociated from the experiences. This makes events associated with surgery peripheral to their whole experience, such that recall is less likely and if it exists, makes any spontaneous report of awareness unlikely. This state of perception-sensation uncoupling is therefore broadly acceptable (a minimum requirement for acceptable anaesthesia) but since it is likely a dose-related phenomenon, may also represent a precursor for awareness with adverse recall. This hypothesis uniquely explains the often inconsistent responses seen during the experimental paradigm of the 'isolated forearm technique', wherein apparently anaesthetised patients exhibit a positive motor response to verbal command, but no spontaneous movement to surgery. The hypothesis can also explain the relatively high incidence of positive response to relatively direct questions for recall (e.g., using the Brice questionnaire; ∼1:500; the vast majority of these being neutral reports) versus the very low incidence of spontaneous reports of awareness (∼1:15,000; a higher proportion of these being adverse recollections). The hypothesis is consistent with relevant notions from philosophical discussions of consciousness, and neuroscientific evidence. Dysanaesthesia has important implications for research and also for the development of appropriate monitoring. Copyright © 2014 Elsevier Inc. All rights reserved.

  20. Statistical errors in Monte Carlo estimates of systematic errors

    Science.gov (United States)

    Roe, Byron P.

    2007-01-01

    For estimating the effects of a number of systematic errors on a data sample, one can generate Monte Carlo (MC) runs with systematic parameters varied and examine the change in the desired observed result. Two methods are often used. In the unisim method, the systematic parameters are varied one at a time by one standard deviation, each parameter corresponding to a MC run. In the multisim method (see ), each MC run has all of the parameters varied; the amount of variation is chosen from the expected distribution of each systematic parameter, usually assumed to be a normal distribution. The variance of the overall systematic error determination is derived for each of the two methods and comparisons are made between them. If one focuses not on the error in the prediction of an individual systematic error, but on the overall error due to all systematic errors in the error matrix element in data bin m, the number of events needed is strongly reduced because of the averaging effect over all of the errors. For simple models presented here the multisim model was far better if the statistical error in the MC samples was larger than an individual systematic error, while for the reverse case, the unisim model was better. Exact formulas and formulas for the simple toy models are presented so that realistic calculations can be made. The calculations in the present note are valid if the errors are in a linear region. If that region extends sufficiently far, one can have the unisims or multisims correspond to k standard deviations instead of one. This reduces the number of events required by a factor of k2. The specific terms unisim and multisim were coined by Peter Meyers and Steve Brice, respectively, for the MiniBooNE experiment. However, the concepts have been developed over time and have been in general use for some time.

  2. A M2FS Spectroscopic Study of Low-mass Young Stars in Orion OB1

    2015-01-01

    Surveys of pre-main sequence stars in the ~4-10 Myr range provide a window into the decline of the accretion phase of stars and the formation of planets. Nearby star clusters and stellar associations allow for the study of these young stellar populations all the way down to the lowest mass members. One of the best examples of nearby 4-10 Myr old stellar populations is the Orion OB1 association. The CIDA Variability Survey of Orion OB1 (CVSO - Briceño et al. 2001) has used the variability properties of low-mass pre-main-sequence (PMS) stars to identify hundreds of K and M-type stellar members of the Orion OB1 association, a number of them displaying IR-excess emission and thought to be representative of more evolved disk-bearing young stars. Characterizing these young, low-mass objects using spectroscopy is integral to understanding the accretion phase in young stars. We present preliminary results of a spectroscopic survey of candidate and confirmed Orion OB1 low-mass members taken during November 2014 and February 2014 using the Michigan/Magellan Fiber Spectrograph (M2FS), a PI instrument on the Magellan Clay Telescope (PI: M. Matteo). Target fields located in the off-cloud regions of Orion were identified in the CVSO, and observed using the low and high-resolution modes of M2FS. Both low and high-resolution spectra are needed in order to confirm membership and derive masses, ages, kinematics and accretion properties. Initial analysis of these spectra reveal many new K and M-type members of the Orion OB1 association in these low extinction, off-cloud areas. These are the more evolved siblings of the youngest stars still embedded in the molecular clouds, like those in the Orion Nebula Cluster. With membership and spectroscopic indicators of accretion we are building the most comprehensive stellar census of this association, enabling us to derive a robust estimate of the fraction of young stars still accreting at a various ages, a key constraint for the end of

This results in shortening and overactivation of these and other muscles. Manual therapy is increasingly being investigated as a way to alleviate these changes. The aim of this study was to measure the immediate effect on lung function of a soft tissue manual therapy protocol (STMTP designed to address changes in the accessory respiratory muscles and their associated structures in patients with severe COPD.Methods: Twelve medically stable patients (n=12 with an existing diagnosis of severe COPD (ten: GOLD Stage III and two: GOLD Stage IV were included. Residual volume, inspiratory capacity and oxygen saturation (SpO2 were recorded immediately before and after administration of the STMTP. A Student’s t-test was used to determine the effect of the manual therapy intervention (P<0.05.Results: The mean age of the patients was 62.4 years (range 46–77. Nine were male. Residual volume decreased from 4.5 to 3.9 L (P=0.002, inspiratory capacity increased from 2.0 to 2.1 L (P=0.039 and SpO2 increased from 93% to 96% (P=0.001.Conclusion: A single application of an STMTP appears to have the potential to produce

    Full Text Available Calcium silicate hydrates are compounds of SiO2 – CaO – H2O system. These materials are used to make lime-sand bricks concretes, or “cellular concretes”, lime-flint brices and as fillers in rubber, paint and plastic products industries, among others. Undoubtedly, the tobermoritas is the most interesting group given its important role in concrete hydration: hydrated calcium silicate (C – S- H is the main concrete hydration product and its primary bounding phase. The hydrothermal method is the most frequently used in the synthesis of these materials. This work shows the synthesis of hydrated calcium silicates through the controlled precipitation method using silicon dioxide SiO2, as raw material obtained from rice husk. The physicochemical phenomena that occur during the calcium silicates synthesis process were analized. The crystalline phases of the final product when exposed to thermic treatments were studied as well using x-ray diffraction and Infrared spectroscopy.

    Los silicatos de calcio hidratados son compuestos del sistema SiO2-CaO-H2O. Estos materiales se utilizan para fabricar ladrillos de cal-arena, hormigones aireados (espumados u “hormigón celular”, ladrillos de cal-flint, como material de relleno en las industrias de productos de caucho, pinturas y plásticos, entre otros posibles usos. Indudablemente el grupo de las tobermoritas es el más interesante debido a su papel importante en la hidratación del cemento: los silicatos tricálcico (3CaO. SiO2-C3S y dicálcico (2CaO, SiO2-C2S son los principales constituyentes del cemento Pórtland.

    In this study, we examined the euphoric effect of propofol and its high satisfaction ratio regarding its liability to be abused, particularly in painless procedures, such as colonoscopy. Fifty subjects aged between 18 and 65 years who fulfilled the criteria for ASA 1-2 and were prepared for colonoscopy were enrolled into this study. For intravenous sedation induction, 2 mg/kg propofol was used, and additional injections were administered according to BIS values. After colonoscopy, the subjects were taken to a recovery room and observed for 30 minutes. Patients were interviewed with the modified Brice questionnare regarding the incidence and the content of dreams. A 5-point Likert scale was used to classify their dreams, and the content of the dreams was also recorded. To assess the subjective effects of propofol, the patients were asked to use the Hall and Van der Castle emotion scale; their biological states were also assessed. The patients' feelings regarding propofol were each rated as absent or present. We used the Morphine-Benzedrine Group scale to measure the euphoric effects of propofol. At the end of the study, subjects scored their satisfaction on a five-point scale. There were no statistically significant differences in sex age, weight, propofol dose, or satisfaction ratio (p>0.05) in the groups, although male patients received a higher dose of propofol and had higher satisfaction ratio. Patients reported no residual after-effects. The incidence of dreaming was 42%. There was no statistically significant difference in dreaming between the sexes, but male patients had a higher dreaming ratio. Dreamers received higher propofol doses and had a higher satisfaction ratio (p>0.05). All dreamers reported happy dreams regarding daily life, and their mean MBG score was 10.5. There was no correlation between MBG scores and propofol doses (r= -0.044, p= 0.761). We conclude that propofol functions as a reward; that patients enjoy its acute effects; and that no

  7. Magnetopause reconnection rate estimates for Jupiter's magnetosphere based on interplanetary measurements at ~5AU

    J. D. Nichols

    2006-03-01

    Full Text Available We make the first quantitative estimates of the magnetopause reconnection rate at Jupiter using extended in situ data sets, building on simple order of magnitude estimates made some thirty years ago by Brice and Ionannidis (1970 and Kennel and Coroniti (1975, 1977. The jovian low-latitude magnetopause (open flux production reconnection voltage is estimated using the Jackman et al. (2004 algorithm, validated at Earth, previously applied to Saturn, and here adapted to Jupiter. The high-latitude (lobe magnetopause reconnection voltage is similarly calculated using the related Gérard et al. (2005 algorithm, also previously used for Saturn. We employ data from the Ulysses spacecraft obtained during periods when it was located near 5AU and within 5° of the ecliptic plane (January to June 1992, January to August 1998, and April to October 2004, along with data from the Cassini spacecraft obtained during the Jupiter flyby in 2000/2001. We include the effect of magnetospheric compression through dynamic pressure modulation, and also examine the effect of variations in the direction of Jupiter's magnetic axis throughout the jovian day and year. The intervals of data considered represent different phases in the solar cycle, such that we are also able to examine solar cycle dependency. The overall average low-latitude reconnection voltage is estimated to be ~230 kV, such that the average amount of open flux created over one solar rotation is ~500 GWb. We thus estimate the average time to replenish Jupiter's magnetotail, which contains ~300-500 GWb of open flux, to be ~15-25 days, corresponding to a tail length of ~3.8-6.5 AU. The average high-latitude reconnection voltage is estimated to be ~130 kV, associated with lobe "stirring". Within these averages, however, the estimated voltages undergo considerable variation. Generally, the low-latitude reconnection voltage exhibits a "background" of ~100 kV that is punctuated by one or two significant

We are very pleased to showcase the keynote addresses from the 5th International Evidence Based Library and Information Practice (EBLIP5 conference that took place in Stockholm, Sweden in July 2009. Andrew Booth, who was Chair of the International Program Committee for the conference, kindly agreed to take on a guest editorial role in gathering these keynote presentations together. I believe it is the first time the EBLIP community has been able to have the keynote papers from an EBLIP conference gathered in this way. Reading these commentaries will give you a true sense of the themes and questions that were woven throughout the conference and will give you lots to think about. For a fuller description and to put this Feature section in context, please be sure to read Andrew’s editorial at the beginning of the section.As we begin our fifth year of publication, submissions of original research articles continue to grow. In this issue we have five original articles on topics ranging from information literacy instruction to cataloguing of e‐books. Two articles look at using communities of practice in the support of evidence based practice; clearly this is an area of emerging research within EBLIP that readers will benefit from learning more about. One of these articles, by Urquhart, Brice, Cooper, Spink, and Thomas, won the Best Oral Presentation award at the EBLIP5 conference.In addition to the original research articles, we also have seven evidence summaries, covering topics such as unionization, information seeking behaviour, and the LIS blogosphere. The EBL101 column tackles critical appraisal, a daunting task that will not seem quite so scary once you’ve read the column!

These findings suggest that regulatory cascades involving DLX5/6 might be at the origin of endometriosis symptoms such as chronic pelvic pain (CPP. We have shown that inactivation of Dlx5 and Dlx5/6 in the mouse uterus results in an endometrial phenotype reminiscent of endometriosis. Methods: We focused on genes that present a similar deregulation in endometriosis and in Dlx5/6-null mice in search of new endometriosis targets. Results: We confirmed a strong reduction of DLX5 expression in endometriosis implants. We identified a signature of 30 genes similarly deregulated in human endometriosis implants and in Dlx5/6-null mouse uteri, reinforcing the notion that the downregulation of Dlx5/6 is an early event in

    Evidence in Practice section uses a standardized format enabling practitioners to share their experience of integrating research evidence into their practice. The final section of these brief articles asks the writers to reflect on their experience. Although it is not research, the individual reflection allies with what Schön (1983 called “reflection on action” and such reflections over time form a practical, tacit knowledge that we use to inform our work. Within this section of the journal, we hope readers will become more aware of how different types of evidence can be integrated into real‐world decision making. Not everything requires a full blown research study, and this section allows readers to see what other practitioners are doing, and in turn it should enable them to reflect upon what they are doing in their own practice. Being aware of situations where things may or may not have worked, and reflecting on the reasons why, brings together our sense of critical thought and practical experience that go a long way in filling the “librarian observed” and “professional judgements” parts of the EBLIP definition (Booth and Brice 2004. Acquiring professional knowledge does not end when we complete a graduate program, or have a certain number of years experience under our belts. It needs to be continually and consciously cultivated via reflection on our practice, our research, and simply what works and why. Research knowledge only takes us so far. People often ask me, “What do I do when there is no evidence? Or when the research evidence is weak?” Does this stop us from moving ahead? No. A decision still needs to be made. Evidence based practice is not only about acting when there is good evidence. Enhancing our professional judgments via a career built on analytical reflection, will provide knowledge that goes a long way towards making difficult decisions a little bit easier; even (or perhaps, especially in the cases when there is already a large body of

(Hasta aquí la transcripción del libro “Contribuci6n para la historia de la Medicina Colombiana” de Rafael Martínez Briceño y Guillermo Hernández de Alba, Bogotá, 1966.

    Esta Real Academia de Medicina se reunio en forma precisa y regular a partir del jueves 6 de febrero de 1817, a mañana y tarde como había sido estipulado, discutiéndose temas tan importantes como: “A qué se da el nombre de enfermedad”; “Salud y Vida, qué sean”; “En qué consiste la vida”; “Qué sea la muerte”; “C6mo puede mirarse la enfermedad”; “Por qué se halla el cuerpo humano sujeto a las enfermedades”, y otros de igual importancia.
