    The 'EPECUR' experimental setup is under construction at beam line 322 of the ITEP proton synchrotron. The experiment requires several large area drift chambers to provide reasonable acceptance and fine-pitch proportional chambers for beam particle tracking. The total number of electronic channels is about 7000. A new compact and cost effective readout system for these gaseous detectors was designed, prototyped and tested in the last two years. It is based on modern technologies in analog and digital electronics and data transfer protocols. This paper presents the functional description of the whole DAQ system, including test results as an illustration of its performance

    The COHERENT Collaboration is realizing a long term neutrino physics research program. The main goals of the program are to detect and study elastic neutrino-nucleus scattering (CEνNS). This process is predicted by Standard Model but it has never been observed experimentally because of the very low energy of the recoil nucleus. COHERENT is using different detector technologies: CsI[Na] and NaI scintillator crystals, a single-phase liquid Ar and a Ge detectors. The placement of all the detector setups is in the basement of the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). The current status of the COHERENT experimental program is presented. (paper)

    Neutron-proton squeeze-out is predicted to provide quantitative information on the symmetry term of the nuclear Equation of State at supra-saturation densities. Hence we designed an experiment consisting out of the CHIMERA charged particle detector for impact parameter determination and reaction plane reconstruction, the LAND neutron detector to measure neutron and proton squeeze-out and a Triple Telescope Array to identify light fragments. Measurements of 197Au+197Au, 96Ru+96Ru and 96Zr+96Zr collisions at 400 A MeV have been accomplished in May 2011 at the GSI facility. Current status of the analysis, first results and future plans are presented.

    2010-01-01

    The RENO (Reactor Experiment for Neutrino Oscillation) is under construction to measure the value of the smallest and unknown neutrino mixing angle θ 13 . The experiment will compare the measured fluxes of electron antineutrinos at two detectors located at 290 m and 1.4 km distances from the center of the Yonggwang nuclear reactors in Korea, with world-second largest thermal power output of 16.4 GW. Construction of experimental halls and access tunnels for both near and far detector sites was completed in early 2009. The detectors are near completion, and data-taking is planned to start in mid 2010. An expected number of observed antineutrino is roughly 510 and 80 per day in the near detector and far detector, respectively. An estimated systematic uncertainty associated with the measurement is less than 0.6%, and an expected statistical error is about 0.3%. With three years of data, the experiment will search for the mixing angle values of sin 2 (2θ 13 ) down to 0.02 in 90% C.L. limit. In this talk, the construction status will be presented. (author)

    Full Text Available The Compressed Baryonic Matter (CBM experiment at the Facility for Anti-Proton and Ion Research (FAIR will explore the phase diagram of strongly interacting matter at highest net baryon densities and moderate temperatures. The CBM physics program will be started with beams delivered by the SIS 100 synchrotron, providing energies from 2 to 11 GeV/nucleon for heavy nuclei, up to 14 GeV/nucleon for light nuclei, and 29 GeV for protons. The highest net baryon densities will be explored with ion beams up to 45 GeV/nucleon energy delivered by SIS 300 in the next stage of FAIR. Collision rates up to 107 per second are required to produce very rare probes with unprecedented statistics in this energy range. Their signatures are complex. These conditions call for detector systems designed to meet the extreme requirements in terms of rate capability, momentum and spatial resolution, and a novel DAQ and trigger concept which is not limited by latency but by throughput. The article discusses the development status of the CBM sub-systems for charged particle tracking, vertex detection, electron/muon identification, hadron/time-of-flight measurement, electromagnetic and zero-degree calorimetry, in terms of prototypes and expected physics performance. The concept and development status of CBM’s central detector, the Silicon Tracking System STS are presented in somewhat more detail.

    The GERDA experiment is designed to search for neutrinoless double beta decay (0νββ) using "7"6Ge, therefore asses the nature of neutrinos (Dirac or Majorana). In the so-called Phase I, with an exposure of 21.6 kr yr, GERDA reached a background index (BI) of 10"−"2 cts/(keV kg yr) at 90% CL No signal was found during this phase and a lower limit on the process half-life of 2.1 × 10"2"5 yr was derived (90% CL). GERDA is currently being upgraded to its Phase II, where the "7"6Ge mass will be double, and it is expected to reduce by an order of magnitude the BI. For 0νββ half-lives at the order of 10"2"6 yr will be derived in the absence of signal. The experimental techniques used by GERDA will be depicted and the most relevant results from Phase I will be shown; as well as details on the upgrades of Phase II, including the status of the additional detectors deployed recently, and the new background reduction techniques using the active liquid Argon veto.

  17. Reducing status quo bias in choice experiments

    DEFF Research Database (Denmark)

    Bonnichsen, Ole; Ladenburg, Jacob

    In stated preference literature, the tendency to choose the alternative representing the status quo situation seems to exceed real life status quo effects. Accordingly, status quo bias can be a problem. In Choice Experiments, status quo bias is found to be strongly correlated with protest attitudes...... toward the cost attribute. If economic values are to be elicited, this problem is difficult to remedy. In a split sample framework we test a novel ex-ante entreaty aimed specifically at the cost attribute and find that it effectively reduces status quo bias and improves the internal validity...

    A large number of experiments are currently trying to observe the phenomenon of neutrino oscillation in various ways. Among these, the CHORUS appearance experiment focuses on v,, ---> vT and v. ---> vT detection through the observation of vT induced interactions in the Wide Band neutrino Beam at SPS (CERN). The vT identification is performed in nuclear emulsions by searching for the decay of the r lepton in a sample of events "enriched" by kinematical selection. The detection technique will be discussed and the measured performances of the apparatus will be reported.

    2011-01-01

    The Alpha Magnetic Spectrometer (AMS) is a high-energy physics experiment built to operate in space. The prototype of the AMS detector was AMS-01, fown in1998 on-board of the space shuttle Discovery (missionSTS-91). Starting from the experience acquired in the high successful AMS-01 mission the detector AMS-02 has been designed improving the AMS-01 energetic range, geometric acceptance and particle identifcation capabilities. In 2010 the AMS-02 detector has been validated for the space/scientifc operations by means of a wide test campaign(including beam tests, TVT test and EMI test). A major change in the design of AMS-02 has been decided after the thermo-vacuum test to extend as much aspossible the endurance of the experiment, profiting also of the extended endurance of the International Space Station (ISS) program toward 2020. The final AMS-02 configuration has been integrated during summer 2010, then tested on the H8 beam-line at CERN, and finally delivered to the launch site (Kennedy Space Center, Florida) at the end of August. AMS-02 is planned to be installed on the International Space Station in 2011 by the space shuttle Endeavour (mission STS-134).

    Full Text Available The study aims to determine fertility status of the soil after organic paddy experiments using kinds and doses of organic fertilizers. Experiment was conducted at greenhouse laboratory in Faculty of Agriculture Sebelas Maret University Surakarta. Experimental design used completely randomized design with 9 kinds of treatment was replicated 3 times. Experiments were the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations that are based on fulfilling nutrient requirements of 120 kg N ha-1. Result shows that the use of cow manure, Azolla fertilizers and Azolla inoculum had no effect on changes of soil fertility status. Soil fertility status was not significantly correlated with cow manure (0,16ns, Azolla fertilizer (0,26ns and Azolla inoculum (0,16ns. Average of final soil fertility status included fertile category, which was similar as the initial soil fertility status. Average of final soil properties of treatment but nevertheless was relatively higher than in no treatment, indicating the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations had greater impact to soil properties. Cow manure despite increased available K2O and dry grain, but it did not significantly increase the soil fertility status from fertile to very fertile. This was presumably due to the relatively short experiment period, only one planting season had not given significant effect to soil properties. Implication of this study is the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations although did not increase the soil fertility status but could maintain soil fertility status as the initial conditions before planting.

    The AEGIS experiment 1 (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is planned to perform the first measurement of the gravitational acceleration on antimatter by observing the free fall of antihydrogen atoms. By combining techniques based on recent developments in the production of positronium and its laser excitation to Rydberg states, such a study seems indeed to be feasible for neutral antimatter. We present here some of the experimental techniques involved in the experiment as well as the status of the detector test envisioned for the gravity measurement.

    Rogers, David V.

    1992-01-01

    The status of the Olympus Propagation Experiment of the Communications Research Centre in Ottawa, Canada, is briefly summarized. Path attenuation measurements at multiple frequencies correlated with concurrent dual polarized radar data provide a unique method to investigate propagation effects. An experiment of this type is being implemented by the Communications Research Centre (CRC) on the grounds of the National Research Council of Canada in Ottawa. Beacon receivers monitor signals from the Olympus satellite at 12.5, 19.77, and 29.66 GHz at a path elevation angle of 14.2 deg. Sky noise radiometers operating near the same frequencies and pointed along the same path provide additional propagation information. A colocated dual-polarized 9.6-GHz radar probes the precipitation state on the path, permitting identification of precipitation regimes that cause the observed impairments. The Olympus experiment configuration is displayed pictorially. Information on path propagation phenomena can be deduced by correlating the radar, beacon, and sky noise data. Melting layer effects and propagation losses for higher time percentages are prime interests. Data collected by Diversitel Communications during equipment verification tests are presented.

    The Gerda experiment searches for the neutrinoless double beta decay (0νββ) in {sup 76}Ge. The first phase of the experiment collected 21.6 kg. yr of exposure with a background index (BI) of 0.01 cts/(keV . kg . yr). No signal was observed and a lower limit for the 0νββ half-life was set to T{sup 0νββ}{sub 1/2} < 2.1 . 10{sup 25} yr (90% C.L). The apparatus has now been upgraded to the Phase II configuration. In Phase II 38 kg of HPGe detectors will be operated to reach an exposure of 100 kg . yr. The goal of Gerda Phase II is to lower the BI to 10{sup -3} cts/(keV . kg . y), in order to reach the sensitivity for T{sup 0νββ}{sub 1/2} = O(10{sup 26}) yr. The additional target mass is constituted of 30 custom made BEGe detectors with higher energy resolution and better pulse shape discrimination performance. The detectors are operated in new radio-pure low-mass holders. The liquid argon surrounding the detectors has been instrumented to veto the background events which produce scintillation light. In this talk the current status and the performance of the Gerda Phase II are presented.

    The relativity experiment on Helios (Experiment 11) uses S-band and Doppler data, and spacecraft-solar-orbital data to measure the effects of general relativity in the solar system and the quadrupole moment in the solar gravitational field. Specifically, Experiment 11 is converned with measuring the following effects: (1) relativistic orbital corrections described by two parameters of the space-time metric which are both equal to unity in Einstein's theory; (2) orbital perturbations caused by a finite quadrupole moment of an oblate sun, described by zonal harmonics in the solar gravitational field.

    The MEG experiment is searching for the lepton flavour violating decay μ + → e + γ since several years. Using the data collected in 2009 and 2010 the experiment set a 90% C.L. upper bound on the branching ratio of this process of 2.4*10 -12 , which is the best limit in the world and updates the previous one by a factor of 5. The experiment continues its data-taking and is expected to reach a sensitivity on the μ + → e + γ branching ratio of a few times 10 -13 in the next few years. Studies for detector upgrades are under way. (author)

    HERA-B is a fixed target experiment using the halo of the 920 GeV proton beam of HERA on an internal wire target. The aim of the experiment is to trigger on rare B to J/ psi decays, using a highly selective trigger system and to measure the CP violating parameter sin (2 beta ). The specific problems of the experiment arise from the extreme background conditions which put unprecedented requirements on the detector components and the triggering and read out system. After 6 years of intense R&D, HERA-B has been finally completed and is now in its commissioning phase.

    After the nuclear criticality had been reached on a uranium-graphite assembly for the first time in the Soviet Union on December 25, 1946, by I.V. Kurchatov and his team (1), the critical conditions in a great variety of multiplying media have been realized only in the Kurchatov Institute for at least several thousand times. Even the first Russian critical experiments carried out by Igor Kurchatov confirmed the unique merits of zero-power reactors: the most practically convenient range of parameters of kinetic response for variation of critical conditions, as well as invariability, over a wide range of the most important functions of neutron flux to reactor power. Neutron physics experiments have become a necessary stage in creation and improvement of nuclear reactors. Most critical experiments were performed mainly as a necessary stage of reactor design in the 60ies and 70ies, which has been the reactor 'golden age', when most of the total of over thousand nuclear reactors of various type and destination have been created worldwide. Though the ways of conducting critical measurements were very diversified, there are two main types of experiments. The first is so-called mock-up or prototype experiments when an exact (to the extent possible) simulation of the core is constructed to minimize the error in forecasting the operating reactor characteristics. Such experiments, which often represent the quality control of the core manufacturing and adjustment of core parameters to the design requirements, were carried out in Russia on critical assemblies of several plants, in design institutions (OKBM, Nizhni Novgorod; Electrostal and others), as well as in research centers (RRC 'Kurchatov Institute', etc.). Their results, which prevail today in the criticality database, even taking into account the capabilities provided by present-day calculation codes, are not well suited for new applications. It is hard to expect that the error resulting from inevitable idealization of

In four years of data acquisition, we expect to decrease the current limit of sin{sup 2}(2{theta}{sub 13}) from 0.2 to 0.03, contributing for the determination of this parameter that is still open in the neutrino mixing matrix. For this, the Double Chooz experiment will use antineutrinos generated in both Chooz plant reactors and will make high accuracy measurements of the flux in two different distances with identical detectors. The first detector (the 'far detector') is already in operation since January 2011 and the construction of the second one (the'{sup n}ear detector') should be completed on the beginning of 2012. Thus, in this work we present the main aspects of this neutrino oscillation experiment and preliminary results of the detector performance. (author)

    Full text: The neutrino oscillation experiment Double Chooz, located at the nuclear power plant of Chooz (Ardennes, France), has as purpose to measure the mixing angle {theta}{sub 13} with greater precision than the measurement of its predecessor, the Chooz experiment. For this, the Double Chooz experiment will use antineutrinos generated in both Chooz plant reactors and will make high accuracy measurements of the flux in two different baselines with identical gadolinium-doped-scintillator detectors, that uses the inverse-beta-decay positron and neutron detection as an antineutrino signature. This signature is given by a prompt signal from the positron and a delayed neutron signal, which allow to decrease significantly the uncorrelated background. Other forms of background, in particular the cosmic correlated one, are managed using different technic. The use of two equal detectors at different baselines will allow to better control our systematic errors, in particular the ones associated with the reactor and with the reactor anomaly effect. The first detector (known as the 'far detector', 1050m from the reactors) is already in operation since April 2011 and the second one (known as the 'near detector', 400m from the reactor) is under construction. Thus, in this work we present the main aspects of this neutrino oscillation experiment and results update. (author)

The G(1590) is to be investigated. Multiquark states need to be studied to establish the scalar nonet. We have some tensor glueball candidates, θ, 3 g T 's and ζ, which are to be further examined. Pseudoscalar states include many interesting physics. Some puzzles were solved. However, many problems remain unsolved and new puzzles appeared. Whether the E and l are the same state or not, and whether the E/l is a glueball or not are the major interests at present. Systematical experimental and theoretical works are required. In an experimental field, radial excitations, especially a radial excitation of η', should be confirmed. In general higher statistics data are necessary to perform a complete partial wave analysis. A 1 ++ isoscalar member, a partner of D(1280), is missing and required to be confirmed as soon as possible. A confirmation of this state will serve to solve the E/l puzzle. The state will be probably an (santi s) state. 1 +- H', a partner of H(1190), is required to be confirmed. Multiquark states are to be investigated. ''Oddballs'' are to be challenged. Recent experiments require high statistics data enough to perform a model-independent partial wave analysis. The (qanti q) - (gg) mixing and hybrids are to be further studied in experimental and theoretical fields. (Nogami, K.)

    We report on the newly developed control system called TRITON and the new data acquisition called TILDA as well as on improved isotope shift measurements of the isotopes {sup 40,42,44,48}Ca in the 4s 2S1/2 → 4p 2P3/2 (D2) transition at the TRIGA-LASER experiment in Mainz using collinear laser spectroscopy. Well known isotope shift measurements in the 4s 2S1/2 → 4p 2P1/2 (D1) transition act as calibration points to reduce the uncertainties in the D2-line to provide reference values for the determination of nuclear charge radii and quadrupole moments of neutron rich calcium isotopes at COLLAPS.

    Aladin2 is an experiment devoted to the first measurement of variations of Casimir energy in a rigid cavity. The main scientific motivation relies on the possibility of the first demonstration of a phase transition influenced by vacuum fluctuations. The principle of the measurement, based on the behaviour of the critical field for an in-cavity superconducting film, will be only briefly recalled, being discussed in detail in a different paper of the same conference (G Bimonte et al 2006 J. Phys. A: Math. Gen. 39 6161). In this paper, after an introduction to the long-term motivations, the experimental apparatus and the results of the first measurement of sensitivity will be presented in detail, particularly in comparison with the expected signal. Last, the most important steps towards the final measurement will be discussed

    Full text: The CHEOPS Collaboration, which includes Australian groups, submitted a Letter of Intent in March 1995 to build a new state-of-the-art spectrometer in the North Area at CERN. The main physics goals is to study baryons with two 'exotic' quarks (ccq or csq, where q is a u- or d-quark). Many subsidiary analyses are possible in the same spectrometer. The CHEOPS physics program will include the study of: semileptonic decays of charmed and doubly charmed baryons; exotic particles ( Glueballs, Hybrids, U(3100) and Di-baryons); Primakof reactions; and hyperon semileptonic decays. The relevant CERN committee (the SPSLC) considered the request favourably. However another experiment, a continuation of the twenty year old program at CERN to study nucleon structure via Deep Inelastic Scattering (DIS) of muons, wants to use the same area at the same time. The SPSLC requested that the two groups try to merge to form a single team or that they agree on ways to share the area. They were invited to submit one or more firm proposals by March 1996.This talk discusses the progress of the 'marriage' between CHEOPS and HMC. It will also review the original CHEOPS physics program given the compromises that have had to be made

    An important experiment for cosmic ray physics is going to be conducted with the colliding proton beams of the CERN LHC. The equivalent energy of the 14 TeV center of mass energy of the colliding proton beams in the LHC is 1017eV in the laboratory frame. Two small electromagnetic calorimeters have been installed at zero degree collision angle +/-140m from the interaction point IP1. The calorimeters measure the energies and the positions of the axes of showers produced by forward neutral particles created in the proton-proton collisions. The shower calorimeters are therefore able to measure the production cross-section of neutral pions emitted in the very forward region. The experimental results will be obtained during the early operation phase of LHC when the luminosity is below 1030cm-2s-1. The data obtained will be extremely important for benchmarking the various Monte Carlo codes used for interpreting super high energy cosmic ray phenomena.

    The main aim of National Spherical Torus Experiment (NSTX) is to establish the fusion physics principles of the innovative spherical torus (ST) concept. The NSTX experimental facility has been operating reliably and its capabilities steadily improving. Due to relatively efficient ohmic current drive and benign halo current behavior, the plasma current was increased to 1.4 MA, which is well above the design value of 1 MA. The plasmas at 1 MA are now routinely heated by NBI to the average toroidal beta value of 20 percent range at 3 kG with electrons and ions in the 1-2 keV range. Even with the “L-mode” edge, the energy confinement time can well exceed the so-called L-mode (and even H-mode) scaling values. As a part of ST tool development, High Harmonic Fast Wave (HHFW) heating has demonstrated efficient electron heating with the central electron temperatures reaching 3.7 keV. HHFW induced H-modes have been also observed. For CHI (Coaxial Helicity Injection) non-inductive start-up, CHI discharges of up to 300 kA of toroidal current and 300 msec duration have been produced from zero current using = 25 kA of injected current. The poster presentation will also include the near term NSTX facility upgrade plan.

    The CERN Axion Solar Telescope (CAST) is currently the most sensitive axion helioscope designed to search for axions produced by the Primakoff process in the solar core. CAST is using a Large Hadron Collider (LHC) test magnet where axions could be converted into X-rays with energies up to 10 keV. During the phase I, the experiment operated with vacuum inside the magnet bores and covered axion masses up to 0.02 eV. In the phase II, the magnet bores were filled with a buffer gas (first (4)He and later (3)He) at various densities in order to extend the sensitivity to higher axion masses (up to f .18 eV). The phase II data taking was completed in 2011. So far, no evidence of axion signal has been found and CAST set the most restrictive experimental limit on the axion-photon coupling constant over a broad range of axion masses. The latest CAST results with (3)He data in the mass range 0.39 eV < ma < 0.64 eV will be presented.

    LACARA (laser cyclotron auto-resonance accelerator) is an 'advanced concept' vacuum laser accelerator of electrons that is in the design and construction phase at the Accelerator Test Facility at Brookhaven National Laboratory. As a bunch moves along a solenoidal magnetic field (∼ 6T), it is to be accelerated from 50MeV to ∼100MeV by interacting with a 0.8TW Gaussian-mode optical beam provided by a CO2 10.6μm laser system. We present a system design here for the electron as well as the laser optics to accomplish this objective. The laser optics must handle 5J and be capable of forming a Gaussian beam inside the solenoid with a 1.3mm waist and a Rayleigh Range of 50cm, followed by a dump. The electron optics will transport a bunch having input emittance of 0.015mm-mrad and 100μm waist through the magnet. Emittance- filtering may be necessary to yield an accelerated bunch having narrow energy-spread. The design presented shows that a useful test of this concept may be done in a way taking into account the specific features and requirements of the ATF facility. It is expected that the experiment will be assembled by October- November 2002

  8. Goals and status of the CBM experiment

    Full Text Available The goal of the heavy-ion collision program at the future Facility for Antiproton and Ion Research (FAIR in Darmstadt (Germany is to explore the phase diagram of strongly interacting matter in the region of the highest baryon densities. The CBM research program addresses fundamental aspects of QCD such as the equation-of-state of highly compressed baryonic matter, the deconfinement phase transition and its critical endpoint, chiral symmetry restoration at high baryon densities, and the in-medium properties of hadrons. The corresponding key observables comprise low-mass vector mesons decaying into lepton pairs which serve as penetrating probes, hidden and open charm produced at threshold beam energies, (multi- strange particles, and global features like collective flow and event-by-event fluctuations. The experimental task is to identify both hadrons and leptons and to detect rare probes in a heavy-ion environment. The experimental challenge is to select rare events in nucleus-nucleus collisions with charged particle multiplicities of about 1000 per central event at reaction rates of up to 10 MHz. Such measurements require fast and radiation hard detectors, fast and selftriggered read-out electronics, a high-speed data acquisition system, and online event selection based on full track reconstruction. The layout of the CBM detector system and the results of feasibility studies will be presented. More than 400 scientists from 50 institutions and 15 countries actually participate in the realization of the CBM experiment which represents a major international effort in future heavy-ion physics.

    The Levitated Dipole Experiment (LDX) is the first experiment designed to study high-β plasmas confined by a magnetic dipole with near classical energy confinement. The primary goal of the initial phase of LDX operation is the study of plasma behavior near marginal stability for interchange modes at high-β. Other areas of investigation include dipole confinement characteristics, the formation of convective cells within the closed field line geometry and the possibility of non-local transport. LDX consists of three superconducting magnets and highlights the role of innovative magnetic technology that makes possible explorations of entirely new confinement concepts. We describe the LDX machine design and detail the fabrication status of the superconducting floating-coil, charging-coil, and levitation-coil as LDX nears plasma operations. An overview of the project goals, overall program plan, and current status of the experiment will also be presented.

    The last unknown neutrino mixing angle θ 13 is one of the fundamental parameters of nature; it is also a crucial parameter for determining the sensitivity of future long-baseline experiments aimed to study CP violation in the neutrino sector. Daya Bay is a reactor neutrino oscillation experiment designed to achieve a sensitivity on the value of sin 2 (2*θ 13 ) to better than 0.01 at 90% CL. The experiment consists of multiple identical detectors placed underground at different baselines to minimize systematic errors and suppress cosmogenic backgrounds. With the baseline design, the expected anti-neutrino signal at the far site is about 360 events per day and at each of the near sites is about 1500 events per day. An overview and current status of the experiment will be presented.

    The Muon g-2 experiment at Fermilab will measure the anomalous magnetic moment of the muon to a precision of 140 parts per billion, which is a factor of four improvement over the previous E821 measurement at Brookhaven. The experiment will also extend the search for the muon electric dipole moment (EDM) by approximately two orders of magnitude. Both of these measurements are made by combining a precise measurement of the 1.45T storage ring magnetic field with an analysis of the modulation of the decay rate of the higher-energy positrons from the (anti-)muon decays recorded by 24 calorimeters and 3 straw tracking detectors. The current status of the experiment as well as results from the initial beam delivery and commissioning run in the summer of 2017 will be discussed.

    The simulation program for the ATLAS experiment is presently operational in a full OO environment. This important physics application has been successfully integrated into ATLAS's common analysis framework, ATHENA. In the last year, following a well stated strategy of transition from a GEANT3 to a GEANT4-based simulation, a careful validation programme confirmed the reliability, performance and robustness of this new tool, as well as its consistency with the results of previous simulation. Generation, simulation and digitization steps on different sets of full physics events we retested for performance. The same software used to simulate the full the ATLAS detector is also used with testbeam configurations. Comparisons to real data in the testbeam validate both the detector description and the physics processes within each subcomponent. In this paper we present the current status of ATLAS GEANT4 simulation, describe the functionality tests performed during its validation phase, and the experience with distrib...

    The Telescope Array(TA) experiment located at western desert in Utah USA (N39.3,W112.9) is designed for observation of air shower from extreme high energy cosmic rays. The TA detector consists of 2 types of detector to enable a cross check on systematic difference from the two main methods of observation for the energy region. One is a Fluorescence detector (FD) for detecting fluorescence light from air shower and another is surface detector (SD) array for detecting air shower particles at ground level. Each SD consists of 2 layers of plastic scintillator with 3m{sup 2} of surface and more sensitive to electromagnetic component in air shower. The full operation using 3FD stations and full SD array has started. Here we present the updated status of Telescope Array experiment.

    Objective: To determine the current status of research experience in psychiatry residency programs across Canada. Method: Coordinators of Psychiatric Education (COPE) resident representatives from all 17 psychiatry residency programs in Canada were asked to complete a survey regarding research training requirements in their programs. Results: Among the 17 COPE representatives, 15 completed the survey, representing 88% of the Canadian medical schools that have a psychiatry residency program. Among the 15 programs, 11 (73%) require residents to conduct a scholarly activity to complete residency. Some of these programs incorporated such a requirement in the past 5 years. Ten respondents (67%) reported availability of official policy and (or) guidelines on resident research requirements. Among the 11 programs that have a research requirement, 10 (91%) require residents to complete 1 scholarly activity; 1 requires completion of 2 scholarly activities. Eight (53%) residency programs reported having a separate research track. All of the programs have a research coordinator and 14 (93%) programs provide protected time to residents for conducting research. The 3 most common types of scholarly activities that qualify for the mandatory research requirement are a full independent project (10 programs), a quality improvement project (8 programs), and assisting in a faculty project (8 programs). Six programs expect their residents to present their final work in a departmental forum. None of the residency programs require publication of residents’ final work. Conclusions: The current status of the research experience during psychiatry residency in Canada is encouraging but there is heterogeneity across the programs. PMID:25565474

    Full Text Available Asha R Aggarwal, Iqbal Khan Department of Medical Education, Northampton General Hospital, Northampton, UK Objectives: In the UK, cardiopulmonary resuscitation (CPR should be undertaken in the event of cardiac arrest unless a patient has a “Do Not Attempt CPR” document. Doctors have a legal duty to discuss CPR with patients or inform them that CPR would be futile. In this study, final-year medical students were interviewed about their experiences of resuscitation on the wards and of observing conversations about resuscitation status to explore whether they would be equipped to have an informed discussion about resuscitation in the future. Methods: Twenty final-year medical students from two medical schools were interviewed about their experiences on the wards. Interviews were transcribed verbatim, and thematic analysis was undertaken.Results: Students who had witnessed CPR on the wards found that aspects of it were distressing. A significant minority had never seen resuscitation status being discussed with a patient. No students reported seeing a difficult conversation. Half of the students interviewed reported being turned away from difficult conversations by clinicians. Only two of the twenty students would feel comfortable raising the issue of resuscitation with a patient. Conclusion: It is vital that doctors are comfortable talking to patients about resuscitation. Given the increasing importance of this aspect of communication, it should be considered for inclusion in the formal communication skills teaching during medical school.

    SNO+ is a large liquid scintillator based experiment that reuses the Sudbury Neutrino Observatory detector. The detector, located 2 km underground in a mine near Sudbury, Canada, consists of a 12 m diameter acrylic vessel which will be filled with 780 tonnes of liquid scintillator. The main physics goal of SNO+ is to search for the neutrinoless double-beta (0νββ) decay of {sup 130}Te. During the double-beta phase, the liquid scintillator will be initially loaded with 0.3-0.5% natural tellurium. In 5 years of data taking, SNO+ expects to reach a sensitivity on the effective Majorana neutrino mass of 55-133 meV, just above the inverted neutrino mass hierarchy region. Recently, the possibility to deploy up to 10 times more natural tellurium has been investigated, by which SNO+ could explore deep into the parameter space for the inverted hierarchy in the near future. Designed as a general purpose neutrino experiment, SNO+ can additionally measure the reactor antineutrino oscillations, geo-neutrinos in a geologically-interesting location, watch supernova neutrinos and measure low-energy solar neutrinos. A first commissioning phase with the detector filled with water will begin soon. The scintillator phase is expected to start after few months of water data taking. The 0νββ decay phase is foreseen for the 2017. In this talk the current status and the broad physics program of SNO+ will be presented.

  6. Status of the Tevatron CDF and D0 experiments

    2010-01-01

    The status of the Tevatron Collider is reviewed and highlights of the rich physics program carried out by the CDF and D0 experiments are presented. The Tevatron Collider has been performing remarkably well in the past few years and it is continuing to deliver record luminosity. The machine collides proton and anti-proton beams at an energy in the center of mass of 1.96 TeV, with average peak luminosity of 300E30 cm -2 s -1 . The total delivered luminosity is slightly above 9 fb -1 . The CDF and D0 experiments have been collecting data with an average efficiency of 90%, while the experiments have enjoyed an annual doubling of the integrated luminosity delivered and recorded. This has led to an avalanche of new results from areas as diverse as QCD, top, searches for new physics and the area of electroweak symmetry breaking with particular focus on direct searches for the Higgs boson. The physics reach of the Tevatron is built on a mountain of measurements that confirm the ability of the Tevatron collaborations to use their detectors to discover new particles. Each measurement is of itself a significant result. Measurements begin with the largest cross section processes, those of B physics, but move on to processes with small branching ratios and backgrounds that are hard to distinguish from the signal. The measurement of Bs oscillations demonstrates the performance of the silicon tracking and vertexing. Discovery of single top production, WZ production, and evidence for the ZZ production in both leptonic and now hadronic modes provide the final base camp from which the Higgs summit is in sight. Processes such as single top and ZZ act as important messengers heralding the impending arrival of the Higgs. This journey through lower and lower cross section processes represents our approach to provide convincing evidence of these processes, first as discovery then as measurements that constrain the Standard Model.

    The Savannah River National Laboratory (SRNL) Radiological Field Lysimeter Experiment is a one-of-a-kind field facility designed to study radionuclide geochemical processes at a larger spatial scale (from grams to tens of kilograms sediment) and temporal scale (from months to 10 years) than is readily afforded through laboratory studies. The lysimeter facility is intended to capture the natural heterogeneity of moisture and temperature regimes in the vadose zone, the unsaturated subsurface region between the surface soil and the underlying aquifer. The 48 lysimeter columns, which contain various radionuclides (and stable iodine), were opened to rainfall infiltration on July 5, 2012. The objective of this report is to provide a status of the lysimeter facility operations and to compile data collected during FY13, including leachate volume, rainfall, and soil moisture and temperature in situ probe data. Radiological leachate data are not presented in this document but will be the subject of a separate document.1 Leachate samples were collected quarterly and shipped to Clemson University for radiological analyses. Rainfall, leachate volume, moisture and temperature probe data were collected continuously. During operations of the facility this year, there were four safety or technical concerns that required additional maintenance: 1) radioactivity was detected in one of the overflow bottles (captured water collected from the secondary containment that does not come in contact with the radiological source material); 2) rainwater accumulated within the sample-bottle storage sheds; 3) overflow containers collected more liquid than anticipated; and 4) significant spider infestation occurred in the sample-bottle storage sheds. To address the first three concerns, each of the lysimeter columns was re-plumbed to improve and to minimize the number of joint unions. To address the fourth concern regarding spiders, new sample-bottle water sheds were purchased and a pest control

    Review of historical and recent experiments which speak in favor of a post-Newtonian relativistic gravitational theory. The topics include the foundational experiments, metric theories of gravity, experiments designed to differentiate among the metric theories, and tests of Machian concepts of gravity. It is shown that the metric field for any metric theory can be specified by a series of potential terms with several parameters. It is pointed out that empirical results available up to date yield values of the parameters which are consistent with the prediction of Einstein's general relativity.

    Much like ordinary matter, dark matter might consist of elementary particles, and weakly interacting massive particles are one of the prime suspects. During the past decade, the sensitivity of experiments trying to directly detect them has improved by three to four orders of magnitude, but solid evidence for their existence is yet to come. We overview the recent progress in direct dark matter detection experiments and discuss future directions.

    Antares is a large, 30 to 40 kJ CO 2 laser system which will provide a base for experiments to determine the efficiency with which 10 μm light can be used to drive target implosions while maintaining an acceptable level of preheat. Construction of the facility is in the final stages and diagnostics for initial experiments are being designed and constructed with operations scheduled to begin early in FY-84. After an initial shakedown period, we expect to perform a series of measurements to determine the energy scaling of hot electron temperature and target coupling efficiency in selected set of targets including simple spheres. We also expect to continue experiments, now planned for Helios, to determine whether CO 2 -produced ions are appropriate for driving inertial fusion targets with acceptable efficiency (Helios experiments have demonstrated that as much as 40% of the incident light can be converted to fast ions). Details of these experiments, as well as plans for further experiments, are still being defined

    In this paper we report about the status of the electrostatic deflector which will be used in K500 superconducting cyclotron at VECC, Kolkata. For extraction of beams from superconducting cyclotron we have to achieve 130 kV/cm. Titanium and tungsten are used for anode and septum respectively. The deflector fits within the median plane of the superconducting magnet. We report here the voltage limit, sparking rates, dark current levels and the effects observed on conditioning. For commissioning of the superconducting cyclotron, the plan is to accelerate Neon beam of 50 MeV/n for which the required extraction voltage is 81 kV/cm and we reached up to 110 kV/cm. The conditioning test chamber is maintained at a pressure of 8.0 x 10 -7 mbar. (author)

    OPERA (Oscillation Project with Emulsion tRacking Apparatus)is an international collaboration between Europe and Asia, aiming to give the first direct proof of tau neutrino appearance in a pure muon neutrino beam, in order to validate the hypothesis for atmospheric neutrino oscillations. The first european long baseline neutrino beam called CNGS is produced at CERN and sent in the direction of the Gran Sasso underground laboratory 730 km away, where the OPERA detector is located. Since 2006 the electronic detector part is fully commissioned and running. Cosmic ray events have been recorded on a regular basis and the first neutrino beam events have been observed in the target elements made of very precise emulsion films and lead sheets during the last run in autumn 2007. This paper reviews the status of the detector, the beam performances, the first results from the neutrino event analysis and the prospects.

    The study of phenomena related to the quantum behavior of macroscopic systems is subjected to new efforts both from theoretical and experimental point of view. The validity in fact of the description of macroscopic systems given by Quantum Mechanics is still under test, especially for what concerns the macrorealistic interpretation of the real world and the influence of dissipation on quantum systems. Many groups tried in the last few years to realize an experimental set-up to perform an MQC experiment; the intrinsic dissipation however limited the possibility to fulfill the experimental requirements. The technology for realizing high quality Josephson Junctions is now so advanced that in principle the tests proposed in the last ten years can hopefully performed with success. In the following we will present a short description of the basic principles for an MQC experiment, with special emphasis on the experiment planned by the Rome group. (author)

    The KamLAND experiment is a very long baseline reactor {nu}-bar{sub e} oscillation experiment. This experiment has sensitivity to the oscillation parameters {delta}m{sup 2} > 10{sup -5} eV{sup 2} and sin{sup 2} 2{theta} > 0.2, using reactor {nu}-bar{sub e} which come typically from 170 km away. This sensitive region completely covers the currently most favored MSW-LMA solution for the solar neutrino deficit problem. After 5 years of detector construction, the data taking started successfully in Jan. 2002. The detector performance is sufficient to perform reactor {nu}-bar{sub e} physics and we expect the first physics result will come out soon. In this paper, the KamLAND detector, its expected sensitivities, history, and recent progress since the time of the conference, are briefly described.

    The main goal of the NPDGamma experiment is to measure the gamma-ray asymmetry with respect to the neutron spin direction in the nuclear reaction n-vector + p {yields} d + {gamma}. The up-down asymmetry A{sub {gamma}} has a predicted size of the order of 5 {center_dot}10{sup - 8} , and the NPDGamma experiment is designed to measure it with an uncertainty of about 10{sup - 8}. To test the entire apparatus the gamma-ray asymmetry from neutron capture was measured using a Cl target followed by measurements on Al to establish the relevant background levels. At present the experiment is taking data with a liquid H{sub 2} target to measure the parity violation on the n-vector + p {yields} d + {gamma} reaction and extract the {Delta}I = 1 part of the hadronic weak interaction.

    The NNCA uses secure remote monitoring systems, both for reporting to the IAEA and for the bilateral cooperation with Sandia (SNL) and Idaho National Laboratory (INL). The NNCA system architecture has changed from a system using a Central Monitoring Station at the former TCNC, to direct internet reporting on a simultaneous basis to the IAEA and the NNCA. The NNCA reporting system is applied at 16 power reactors. This experience provides the basis for a detailed cost analysis and evaluation of trouble-shooting experience. Progress in establishing remote monitoring cooperation between the Korea Atomic Energy Research Institute's new Advanced Spent Fuel Conditioning Process Facility (ACPE) and Sandia is a precondition for regional cooperation. The ACPF system, which is currently in final testing, features network configuration and equipment that differ from safeguards standards for reasons of cost and flexibility. This allows the NNCA to take advantage of rapidly developing technologies at lower cost. (author)

    The Large Hadron Collider forward (LHCf) experiment is a special purpose experiment dedicated to measure the production of neutral particles at the very forward region of the LHC. The data are useful to verify hadronic interaction that influence the development of an air shower. Until now data have been obtained for p-p collisions at $\\sqrt{s} = 0.9$ and 7 TeV and p-Pb collisions at $\\sqrt{s} = 5.02$ TeV/n. Here we will discuss the energy spectra for gamma rays, $\\pi^{0}$s and neutrons from the obtained data. In addition we will also discuss the prospects of 13 TeV p-p collisions as well as that for the possible future measurement of p-p or p-light ions collision data in the very forward region at RHIC or at LHC.

    The objective of the Texas uranium survey experiment is to evaluate an improved method for prospecting for uranium by determining correlations among (a) geologic analysis, (b) soil sample radiochemical analysis, (c) aerial radiometric data, (d) aerial infrared scans, and (e) aerophotographic data. Although aerial radiometric measurements have been used previously in mineral prospecting, the development of useful correlative techniques based on analysis of data from large terrestrial areas employing the five parameters (a through e, above) remains to be evaluated, and could be of significant value to the need for establishing uranium resource pools to meet the nation's energy crisis. The Texas uranium survey field experiment began on June 13, 1973, employing a Martin-404 aircraft to fly gamma-ray recording equipment at a 500-ft altitude over two areas in southeast Texas. The areas surveyed are referred to as the Dubose area (approximately 120 sq. miles) and the Clay West area (approximately 24 sq. miles). This document briefly summarizes the work which has been done, describes the kind and quality of calibrations and data analysis carried out thus far and outlines recommended additional work which would bring the experiment to some degree of completion, providing a basis for evaluating the techniques

    Full Text Available In the field of fundamental particle physics, the neutrino has become more and more important in the last few years, since the discovery of its mass. In particular, the ultimate nature of the neutrino (if it is a Dirac or a Majorana particle plays a crucial role not only in neutrino physics, but also in the overall framework of fundamental particle interactions and in cosmology. The only way to disentangle its ultimate nature is to search for the neutrinoless double beta decay. The idea of LUCIFER is to combine the bolometric technique proposed for the CUORE experiment with the bolometric light detection technique used in cryogenic dark matter experiments. The bolometric technique allows an extremely good energy resolution while its combination with the scintillation detection offers an ultimate tool for background rejection. The goal of LUCIFER is not only to build a background-free small-scale experiment but also to directly prove the potentiality of this technique. Preliminary tests on several detectors containing different interesting DBD emitters have clearly demonstrated the excellent background rejection capabilities that arise from the simultaneous, independent, double readout of heat and scintillation light.

    The US Long Baseline Neutrino Experiment Study was commissioned jointly by Brookhaven National Laboratory and Fermi National Accelerator Laboratory to investigate the potential for future U.S. based long baseline neutrino oscillation experiments beyond the currently planned program. The Study focused on MW class convention at neutrino beams that can be produced at Fermilab or BNL. The experimental baselines are based on two possible detector locations: (1) off-axis to the existing Fermilab NuMI beamline at baselines of 700 to 810 km and (2) NSF's proposed future Deep Underground Science and Engineering Laboratory (DUSEL) at baselines greater than 1000 km. Two detector technologies are considered: a megaton class Water Cherenkov detector deployed deep underground at a DUSEL site, or a 100kT Liquid Argon Time-Projection Chamber (TPC) deployed on the surface at any of the proposed sites. The physics sensitivities of the proposed experiments are summarized. We find that conventional horn focused wide-band neutrino beam options from Fermilab or BNL aimed at a massive detector with a baseline of > 1000 km have the best sensitivity to CP violation and the neutrino mass hierarchy for values of the mixing angle {theta}{sub 13} down to 2.2{sup o}.

    In the Edelweiss experiment, nuclear recoils induced by elastic collisions with WIMPs (weakly interacting massive particle) from the galactic halo are identified in low-temperature Ge detectors where the ratio of the heat and ionization signals provide an event-by-event discrimination of nuclear recoils from the dominant background coming from γ-rays interactions. The Edelweiss experiment is located in the Modane underground facility in order to cut the muon flux drastically. We present here the results obtained during the first part of the experiment named Edelweiss-I that ended in the beginning of 2004. Since october 2002, 3 optimized 320 grams detectors have been simultaneously operated at a regulated temperature of 0.017 K and about 50 kg*day were added to the previous published data. These data are still under analysis but preliminary results concerning the upper limit at 90% CL (confidence level) confirm the limit already published in 2002. The first run of Edelweiss-II is due to begin during summer 2005, we are expecting to gain 2 orders of magnitude in terms of detector sensitivity and reach 0.002 events/day*kg. (A.C.)

    A radiochemical 71 Ga- 71 Ge experiment to determine the primary flux of neutrinos from the Sun began measurements of the solar neutrino flux at the Baksan Neutrino Observatory in 1990. The number of 71 Ge atoms extracted from 30 tons of gallium in 1990 and from 57 tons of gallium in 1991 was measured in twelve runs during the period of January 1990 to December 1991. The combined 1990 and 1991 data sets give a value of 58 + 17/ - 24 (stat.) ± 14 (syst.) SNU. This is to be compared with 132 SNU predicted by the Standard Solar Model. 2 tabs, 1 fig, 14 refs

    The DAMIC experiment uses fully depleted, high resistivity CCDs to search for dark matter particles. With an energy threshold $\\sim$50 eV$_{ee}$, and excellent energy and spatial resolutions, the DAMIC CCDs are well-suited to identify and suppress radioactive backgrounds, having an unrivaled sensitivity to WIMPs with masses $<$6 GeV/$c^2$. Early results motivated the construction of a 100 g detector, DAMIC100, currently being installed at SNOLAB. This contribution discusses the installation progress, new calibration efforts near the threshold, a preliminary result with 2014 data, and the prospects for physics results after one year of data taking.

    The aim of the CP LEAR experiment is to study symmetry-violation effects, making use of tagged K 0 's and anti K 0 's. The detector, although missing some electronic components, has been operational for a few weeks at the end of 1989 at the CERN Low-Energy Antiproton Ring (LEAR). At the moment, the analysis of the data is in progress. This paper gives a description of the experimental method and of the detector; the sensitivities of some measurements and some preliminary results are also discussed. (orig.)

    Primary goal of the WITCH experiment is to test the Standard Model for a possible admixture of a scalar or tensor type interaction in β-decay. This information will be inferred from the shape of the recoil energy spectrum. The experimental set-up was completed and is under intensive commissioning at ISOLDE (CERN). It combines a Penning trap to store the ions and a retardation spectrometer to probe the recoil ion energy. A brief overview of the WITCH set-up and the results of commissioning tests performed until now are presented. Finally, perspectives of the physics program are reviewed.

    Full Text Available SNO+ is a large liquid scintillator-based experiment located 2 km underground at SNOLAB, Sudbury, Canada. It reuses the Sudbury Neutrino Observatory detector, consisting of a 12 m diameter acrylic vessel which will be filled with about 780 tonnes of ultra-pure liquid scintillator. Designed as a multipurpose neutrino experiment, the primary goal of SNO+ is a search for the neutrinoless double-beta decay (0νββ of 130Te. In Phase I, the detector will be loaded with 0.3% natural tellurium, corresponding to nearly 800 kg of 130Te, with an expected effective Majorana neutrino mass sensitivity in the region of 55–133 meV, just above the inverted mass hierarchy. Recently, the possibility of deploying up to ten times more natural tellurium has been investigated, which would enable SNO+ to achieve sensitivity deep into the parameter space for the inverted neutrino mass hierarchy in the future. Additionally, SNO+ aims to measure reactor antineutrino oscillations, low energy solar neutrinos, and geoneutrinos, to be sensitive to supernova neutrinos, and to search for exotic physics. A first phase with the detector filled with water will begin soon, with the scintillator phase expected to start after a few months of water data taking. The 0νββ Phase I is foreseen for 2017.

    Recent NSTX high power divertor experiments have shown significant and recurring benefits of solid lithium coatings on plasma facing components to the performance of divertor plasmas in both L- and H- mode confinement regimes heated by high-power neutral beams. The next step in this work is the 2009 installation of a Liquid Lithium Divertor (LLD). The 20 cm wide LLD located on the lower outer divertor, consists of four, 80 degree sections; each section is separated by a row of graphite diagnostic tiles. The temperature controlled LLD structure consists of a 0.01cm layer of vacuum flame-sprayed, 50 percent porous molybdenum, on top of 0.02 cm, 316-SS brazed to a 1.9 cm Cu base. The physics design of the LLD encompasses the desired plasma requirements, the experimental capabilities and conditions, power handling, radial location, pumping capability, operating temperature, lithium filling, MHD forces, and diagnostics for control and characterization.

    LHCf is an experiment currently installed at CERN at the LHC complex. It consists of two small calorimeters each one placed 140 meters away from the ATLAS interaction point. Their purpose is to study forward production of neutral particles in proton-proton collisions at extremely low angles. The results will provide invaluable inputs to the many air-shower Monte Carlo codes currently used for modeling cosmic rays interactions in the Earth atmosphere. Depending on machine start up, data will be taken from 900 GeV in the centre of mass up to 14 TeV (laboratory equivalent collision energy of 1017eV), thus covering an energy range up to and beyond the “knee” of the cosmic ray spectrum.

    The Telescope Array (TA) experiment is designed to observe cosmic-ray-induced air showers at extremely high energies. It is being deployed in a desert of Utah (Usa); an array of 3 m{sup 2} scintillation counters will be distributed over 760 km{sup 2} and 3 sets of air fluorescence telescopes will be placed in the perimeter of the array. Its primary purpose is to make a decisive measurement of the cosmic ray spectrum in the GZK (Greisen, Zatsepin and Kuzmin) cutoff region. We expect the first data from the TA in the spring 2007. As its unique features are included: 1) hybrid measurement planned down to 10{sup 17.5} eV; 2) calibration of fluorescence detection by using artificial air showers generated by an electron line; and 3) interaction model calibration by the LHC.

    The OPERA experiment, placed 730 km downstream the CERN neutrino beam to Gran Sasso (CNGS) in the LNGS underground laboratory, is designed to measure muon-neutrino to tau-neutrino oscillations in a direct appearance mode. The hybrid apparatus consists of an emulsion/lead target complemented by electronic detectors. Due to the target structure made of thin lead plates, OPERA is able to detect electromagnetic showers, allowing searches for tau electronic decays and for oscillations from muon-neutrino to electron-neutrino. The experimental set-up and associated facilities used to extract data recorded in the emulsion will be described, with the special procedures aimed at locating interaction vertices and detect short decay topologies. OPERA is taking data since 2008. A first nu-tau interaction candidate was already published in 2010. New results with increased statistics will be presented. In particular, an overview of the studies related to electrons will be shown. (author)

    The Los Alamos tritium experiment employs a gaseous tritium source and a magnetic spectrometer to determine the mass of the electron antineutrino from the shape of the tritium beta spectrum. Since publication of the first result from this apparatus (m/sub nu/ < 27 eV at 95% confidence), work has concentrated on improving the data rates. A 96-element Si microstrip array detector has been installed to replace the single proportional counter at the spectrometer focus, resulting in greatly increased efficiency. Measurements of the 1s photoionization spectrum of Kr now obviate the need for reliance on the theoretical shakeup and shakeoff spectrum of Kr in determining the spectrometer resolution. 19 refs., 3 figs

    1990-01-01

    Experiment E855 was carried out at the AGS at Brookhaven National Laboratory to study soft photon production near center of mass rapidity Y cm ∼ 0 in proton-nucleus collisions at 10 at 18 GeV/c. This was the first dedicated experiment to study this phenomenon at these lower energies. It is important to note that the related process of low mass dilepton pair production has been studied extensively at these energies and an excess signal of dileptons above known hadronic backgrounds has been firmly established. E855 was designed to measure photon production from P t ∼ 5 MeV/c up to several GeV/c. A search will be made for an excess of soft photons in the P t region below the Jacobian peak from π 0 decays, above that which is expected from hadronic bremsstrahlung. Any observed signal will be correlated with the total charged multiplicity in the event in order to determine its production mechanism. This correlation can be used to distinguish purely hadronic sources of soft photons, such as mesons decays and bremsstrahlung, which vary linearly with the charged multiplicity, and a thermal source of soft photons which would exhibit a quadratic dependence on the charged multiplicity. In addition, E855 will measure low energy photons from nuclear decays which can be a background for measuring soft photons near Y cm ∼ 0. These photons are also interesting from a nuclear physics point of view, since the spectrum of photons from nuclei excited by incident high energy protons gives a measure of the temperature of the excited nucleus and the amount of excitation energy which can be transferred to a nucleus in a high energy proton collision

  5. Undergraduate engineering student experiences: Comparing sex, gender and switcher status

    Science.gov (United States)

    Fergen, Brenda Sue

    This dissertation explores undergraduate engineering experiences, comparing men with women and switchers with non-switchers. Factors related to a chilly academic climate and gender-role socialization are hypothesized to contribute to variations in men's and women's academic experiences and persistence rates. Both quantitative and qualitative data are utilized in an effort to triangulate the findings. Secondary survey data, acquired as result of a 1992 Academic Environment Survey, were utilized to test the hypothesis that sex is the most important predictor (i.e., demographic variable) of perceptions of academic climate. Regression analyses show that sex by itself is not always a significant determinant. However, when sex and college (engineering vs. other) are combined into dummy variables, they are statistically significant in models where sex was not significant alone. This finding indicates that looking at sex differences alone may be too simplistic. Thirty personal interviews were conducted with a random stratified sample of undergraduate students from the 1993 engineering cohort. The interview data indicate that differences in childhood socialization are important. With regard to persistence, differences in socialization are greater for switchers vs. non-switchers than men vs. women. Thus, gender-role socialization does not appear to play as prominent a role in women's persistence as past literature would indicate. This may be due to the self-selection process that occurs among women who choose to pursue engineering. Other aspects of childhood socialization such as parents' level of educational and occupation, students' high school academic preparation and knowledge of what to expect of college classes appear to be more important. In addition, there is evidence that, for women, male siblings play an important role in socialization. There is also evidence that women engineering students at Midwestern University face a chilly academic climate. The factors which

    The Karlsruhe Tritium Neutrino (KATRIN) experiment uses the kinematics of tritium β-decay to determine the electron antineutrino mass with a sensitivity of m{sub ν}=200 meV/c{sup 2} (90 % C.L.). In order to measure the decay electrons it is important to guide them adiabatically from the source to the spectrometer. In addition the diffusion of tritium into the spectrometers from the source has to be reduced by 14 magnitudes of order as tritium inside the spectrometers would induce additional background. For these two tasks the transport and pumping section were constructed. The last part of this section is the Cryogenic Pumping Section (CPS), which aims to reduce the residual gas flow by not less than seven orders of magnitude. For this a 3 K cold argon frost area (surface ∼ 2 m{sup 2}) will be prepared to adsorb the incoming tritium molecules. This talk will present the milestones which were reached since the CPS arrived on 30th July 2015 on KIT. Amongst others the calculations of the magnetic flux tube through the CPS based on as-built measurements of the coil geometries are presented.

    Muon ionization cooling provides the only practical solution to prepare high brilliance beams necessary for a neutrino factory or muon colliders. The muon ionization cooling experiment (MICE) is under development at the Rutherford Appleton Laboratory (UK). It comprises a dedicated beam line to generate a range of input emittance and momentum, with time-of-flight and Cherenkov detectors to ensure a pure muon beam. A first measurement of emittance is performed in the upstream magnetic spectrometer with a scintillating fiber tracker. A cooling cell will then follow, alternating energy loss in liquid hydrogen and RF acceleration. A second spectrometer identical to the first one and a particle identification system provide a measurement of the outgoing emittance. By July 2009 it is expected that the beam and first set of detectors will have been commissioned and a first measurement of input beam emittance may be reported. Along with the steps in the measurement of emittance reduction (cooling) that will follow later and in 2010. (authors)

    The ARGO-YBJ experiment, located at Yangbajing, Tibet, China, performed by a wide Sino-Italian collaboration, is designed to study cosmic rays, sub-TeV gamma ray sources and GeV Gamma Ray Burst (GRB) emission in the northern hemisphere, by means of detecting small size EAS (Extensive Air Shower) using a full coverage RPC (Resistive Plate Chamber) carpet. The central carpet of the detector is installed and put into operation to date, with 1900m{sup 2} of the carpet already operating since December 2004. With a trigger multiplicity of {>=}60 hits, corresponding to a primary mode energy of 2 TeV, the angular resolution of EAS measurements is < 1{sup o} for showers with more than 500 recorded hits. We report the preliminary results of data taking performed during 2005: the all-sky survey for gamma ray sources and the search for GRBs, as well as the cosmic ray spectrum up to about 100 TeV. The Forbush decrease of the cosmic ray flux during January, 2005 is observed using the ARGO data.

    The neutron spectrum measurement by TOF was designed. In this report, the experimental set-up and preliminary experiments are described. At first, the steady spectra in an assembly was analyzed by the SN method. The time-dependent spectra were also analyzed by the SN method. The target for neutron production was made of tungsten, and set in a spherical graphite assembly. There are an electron beam hole and a re-entrant hole in the graphite assembly. Collimators were set in the flight path, and Cd plates were set to remove thermal neutrons. The detectors were a Li-6 glass scintillator for keV neutrons and a NE-213 scintillator for MeV neutrons. The accuracy of measurement was estimated for energy and neutron intensity. The overall accuracy of 5 percent can be attained. The efficiency calibration of a fast neutron detector was made by using a Cf-252 source. The counting loss in the time-to-pulse-height converter (TPHC) was corrected. (Kato, T.)

    In the present study we used a mixed-method design to examine perceptions of legal status and their association with psychosocial experiences among undocumented Latino/a immigrants in the United States Participants were asked to compare their perceived social experiences with those of documented Latinos/as in order to determine whether differences in such perceptions might emerge and whether such perceptions might differentially impact well-being. A community sample of 140 self-reported undocumented Latino/a immigrants completed questionnaires measuring perceptions of legal status, well-being (global and psychological), perceived context of reception, and experiences of discrimination. Results indicated that individuals who perceived their experiences as different from those of documented Latinos/as due to an unauthorized legal status reported less social equality as evidenced by lower well-being, increased experiences of discrimination, and a more adverse context of reception. Moreover, individuals who perceived their social experiences as different from those of documented Latinos/as due to their legal status reported issues centering on 2 domains: limited opportunity/restricted social mobility and discrimination/unfair treatment. Theoretical and practical implications are discussed in terms of advancing theory and from a multicultural counseling perspective. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    American Indian (AI) boarding school attendance is related to poor physical health status; however, little is known about how specific aspects of this experience contribute to poor health. Five experiences (age of first attendance, limited family visits, forced church attendance, prohibition on practicing AI culture and traditions, and punishment for use of AI language) may be independently associated with physical health status in adulthood. We expected the effect to be greater for those who began boarding school at older ages. Data on AI boarding school attenders (n = 771) came from the AI-Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project. Multiple linear regression models examined the association of these five experiences with physical health status. Additionally, we conducted a separate set of regressions to test for an interaction effect of age of first attendance. Each of the five experiences noted above were independently associated with poorer physical health status compared to those who did not have these experiences. An interaction effect for those punished for use of AI language and who were aged 8 or older was confirmed. Findings are consistent with reports that boarding school attendance is related to poor AI adult health. To inform AI health programs, the relationship of specific diseases and boarding school attendance should be considered.

    Full Text Available While accelerator particle physics has traditionally focused on exploring dark matter through highenergy experiments, testing dark-sectors hypothesis requires innovative low energy experiments that use highintensity beams and high-sensitivity detectors. In this scenario attractive opportunities are offered to low energy machines and flavour experiments. In this paper we will focus our attention on the Dark Photon (DP scenario, reviewing the current status of searches and new opportunities with particular attention to the PADME experiment at Laboratori Nazionali di Frascati.

    Stratospheric Controlled Perturbation Experiment (SCoPEx), is a scientific experiment to advance understanding of stratospheric aerosols. It aims to make quantitative measurements of aerosol microphysics and atmospheric chemistry to improve large-scale models used to assess the risks and benefits of solar geoengineering. A perturbative experiment requires: (a) means to create a well-mixed, small perturbed volume, and (b) observation of time evolution of chemistry and aerosols in the volume. SCoPEx will used a propelled balloon gondola containing all instruments and drive system. The propeller wake forms a well-mixed volume (roughly 1 km long and 100 meters in diameter) that serves as an experimental `beaker' into which aerosols (e.g., budget, etc; (d) results from CFD simulation of propeller wake and simulation of chemistry and aerosol microphysics; and finally (e) proposed concept of operations and schedule. We will also provide an overview of the plans for governance including management of health safety and environmental risks, transparency, public engagement, and larger questions about governance of solar geoengineering experiments. Finally, we will briefly present results of laboratory experiments of the interaction of chemical such as ClONO2 and HCl on particle surfaces relevant for stratospheric solar geoengineering.

    In this paper we study consumers' interest in acquiring and displaying expensive luxury products. Based on recent insights in consumer psychology, which build on developments in evolutionary biology, we consider luxury products as "costly signals": wasteful and costly goods, whose purpose is to communicate one's biological fitness, and social status, to others. In line with previous research, we show that experiences that trigger mate attraction goals (Study 1: Exposure to others in bathing outfit) or status display goals (Study 2: Experiencing a vicarious victory of one's favorite sports team) can increase people's interest in luxury products. However, we demonstrate that some individuals are predictably more responsive to those experiences than others. We used a physiological measure (the proportion of the length of the index finger and ring finger of the right hand, 2D:4D) as a proxy for individual differences in exposure to prenatal androgens (i.e., testosterone). This measure has been related to dominant and competitive behavior later in life. We predict and find that individuals with a low 2D:4D (i.e., high exposure to prenatal androgens) were more responsive to the status-relevant experiences: they became more interested in luxury goods after these experiences. This was not the case for high 2D:4D individuals.

  2. Mere experience of low subjective socioeconomic status stimulates appetite and food intake.

    Among social animals, subordinate status or low social rank is associated with increased caloric intake and weight gain. This may reflect an adaptive behavioral pattern that promotes acquisition of caloric resources to compensate for low social resources that may otherwise serve as a buffer against environmental demands. Similarly, diet-related health risks like obesity and diabetes are disproportionately more prevalent among people of low socioeconomic resources. Whereas this relationship may be associated with reduced financial and material resources to support healthier lifestyles, it remains unclear whether the subjective experience of low socioeconomic status may alone be sufficient to stimulate consumption of greater calories. Here we show that the mere feeling of lower socioeconomic status relative to others stimulates appetite and food intake. Across four studies, we found that participants who were experimentally induced to feel low (vs. high or neutral) socioeconomic status subsequently exhibited greater automatic preferences for high-calorie foods (e.g., pizza, hamburgers), as well as intake of greater calories from snack and meal contexts. Moreover, these results were observed even in the absence of differences in access to financial resources. Our results demonstrate that among humans, the experience of low social class may contribute to preferences and behaviors that risk excess energy intake. These findings suggest that psychological and physiological systems regulating appetite may also be sensitive to subjective feelings of deprivation for critical nonfood resources (e.g., social standing). Importantly, efforts to mitigate the socioeconomic gradient in obesity may also need to address the psychological experience of low social status.

  3. Can decision biases improve insurance outcomes? An experiment on status quo bias in health insurance choice.

    Rather than conforming to the assumption of perfect rationality in neoclassical economic theory, decision behavior has been shown to display a host of systematic biases. Properly understood, these patterns can be instrumentalized to improve outcomes in the public realm. We conducted a laboratory experiment to study whether decisions over health insurance policies are subject to status quo bias and, if so, whether experience mitigates this framing effect. Choices in two treatment groups with status quo defaults are compared to choices in a neutrally framed control group. A two-step design features sorting of subjects into the groups, allowing us to control for selection effects due to risk preferences. The results confirm the presence of a status quo bias in consumer choices over health insurance policies. However, this effect of the default framing does not persist as subjects repeat this decision in later periods of the experiment. Our results have implications for health care policy, for example suggesting that the use of non-binding defaults in health insurance can facilitate the spread of co-insurance policies and thereby help contain health care expenditure.

    Abstarct: Liquid metal walls have been proposed to address the first wall challenge for fusion reactors. The lithium tokamak experiment (LTX) at the Princeton Plasma Physics Laboratory (PPPL) is the first magnetic confinement device to have liquid metal plasma-facing components (PFC's) that encloses virtually the entire plasma. In the current drive experiment-upgrade (CDX-U), a predecessor to LTX at PPPL, the highest improvement in energy confinement ever observed in ohmically heated tokamak plasmas was achieved with a toroidal liquid lithium limiter. The LTX extends this liquid lithium PFC by using a conducting conformal shell that almost completely surrounds the plasma. By heating the shell, a lithium coating on the plasma-facing side can be kept liquefied. A consequence of the low-recycling conditions from liquid lithium walls is the need for efficient plasma fueling. For this purpose, a molecular cluster injector is being developed. Future plans include the installation of a neutral beam for core plasma fueling, and also ion temperature measurements using charge-exchange recombination spectroscopy (CHERS). Low edge recycling is also predicted to reduce temperature gradients that drive drift wave turbulence. Gyrokinetic simulations are in progress to calculate fluctuation levels and transport for LTX plasmas, and new fluctuation diagnostics are under development to test these predictions.

    To assess intergenerational associations between dental caries and nutritional status, oral hygiene habits, and diet. A cross-sectional study was conducted with three generations of 54 families. Inclusion criteria were senior citizens with an adult son/daughter who also had a child (five to 12 years old). Dental caries was assessed using the decayed, missing, filled, primary teeth (dmft) and permanent teeth (DMFT) indexes. Nutritional status was evaluated using the body mass index (BMI), waist circumference, and percentage of body fat. Dietary habits, oral hygiene habits, and socioeconomic status were evaluated using a structured questionnaire. Children/adolescents with higher BMI had a lower dmft/DMFT index, and those who never or almost never consumed fruits and vegetables as snacks had a higher dmft/ DMFT index. When parents did not visit the dentist regularly, children/adolescents had more teeth affected by dental caries. When parents consumed sugar two or more times between meals, the number of affected teeth in children/adolescents increased. When children/ adolescents had a higher body mass index and they consumed fruits/vegetables as snacks more frequently, their caries experiences were lower. When their parents' did not visit the dentist regularly and they consumed sugar between meals more frequently, the children's caries experiences were higher.

    The CRESST-III experiment, located in the Gran Sasso underground laboratory (LNGS, Italy), aims at the direct detection of dark matter (DM) particles. Scintillating CaWO4 crystals operated as cryogenic detectors are used as target material for DM-nucleus scattering. The simultaneous measurement of the phonon signal from the CaWO4 crystal and of the emitted scintillation light in a separate cryogenic light detector is used to discriminate backgrounds from a possible dark matter signal. The experiment aims to significantly improve the sensitivity for low-mass (≲ 5-10 GeV/c2) DM particles by using optimized detector modules with a nuclear recoil-energy threshold ≲ 100 eV. The current status of the experiment as well as projections of the sensitivity for spin-independent DM-nucleon scattering will be presented.

    This article examines the intersecting roles of gender, ethnicity, and professional status in shaping the experiences of internationally educated health professionals in Canada. The article is based on 140 semi-structured qualitative interviews with internationally trained nurses and physicians who came to Canada within past 10 years with the intention to practice their profession. Describing the challenging process of professional integration in Canada, our participants highlighted incidents of discrimination they experienced along the way. Although some of the participants from both professional groups experienced racial discrimination, the context of those experiences differed. Physicians rarely reported instances of discrimination in communication with patients or nurses. Instead, they were concerned with instances of discrimination within their own professional group. Nurses, on the other hand, reported discrimination at the hands of patients and their families as well as racialization by physicians, management, and other nurses. We conclude our article with a reflection on the role that gender and professional status play in shaping the experiences of ethnic discrimination of internationally educated health professionals. © The Author(s) 2015.

    The basis of the G 0 experiment is a parity-violating process giving access to the strange form factors of the proton. It requires the measurement of a set of asymmetries, in elastic electron scattering from hydrogen and quasi-elastic scattering from deuterium, at different Q 2 and at different angles. The experimental site is the Thomas Jefferson National Accelerator Facility (J Lab.), Newport News, VA (USA). The formalism that connects asymmetries with the proton properties at the quark level, the experimental set-up and the present status are described. A section is devoted to a special electronic module, built at the IPN-Orsay, using Digital Signal Processors (DSPs)

    (i) Quantify the relative association between child dental caries experience and maternal-reported child oral health-related quality of life (OHRQoL); (ii) examine whether that association differed according to family socioeconomic status (SES); and (iii) explore whether absolute OHRQoL varied by family SES at similar levels of child caries experience. This study was a cross-sectional analysis of children in southern Brazil (n=456, mean age: 38 months) participating in an existing health centre-based intervention study. OHRQoL impact was quantified as mean score on the Brazilian Early Childhood Oral Health Impact Scale (ECOHIS) and compared over categories of caries experience (dmft: 0, dmft: 1-4, dmft: ≥5). Adjusted ECOHIS ratios between caries categories were calculated using regression modelling, overall and within socioeconomic strata defined by maternal education, social class and household income. Caries prevalence (dmft >0) was 39.7%, mean ECOHIS score was 2.0 (SD: 3.5), and 44.3% of mothers reported OHRQoL impact (ECOHIS score >0). Increasing child caries experience was associated with worsening child and family quality of life: ECOHIS scores were 3.0 times greater (95% CI: 2.0, 4.4) for children with dmft ≥5 vs dmft=0, a pattern that persisted regardless of family socioeconomic status (P for interaction: all >0.3). However, adjusted for dental status and sociodemographic characteristics, mean ECOHIS scores were lower when reported by mothers of less educational attainment (ratio: 0.7; 95% CI: 0.5, 1.0), lower social class (ratio: 0.7; 95% CI: 0.5, 1.0) or in lower income households (ratio: 0.8; 95% CI: 0.6, 1.3). Dental caries was associated with negative child and family experiences and lower OHRQoL across all social groups; yet, families facing greater disadvantage may report lesser quality-of-life impact at the same level of disease experience. Thus, subjective quality-of-life measures may differ under varying social contexts, with possible

    The Microwave Source Facility at the Lawrence Livermore National Laboratory (LLNL) is studying the application of induction accelerator technology to high-power microwave generators suitable for linear collider power sources. The authors report on the results of two experiments, both using the Choppertron's 11.4 GHz modulator and a 5-MeV, 1-kA induction beam. The first experimental configuration has a single traveling wave output structure designed to produce in excess of 300 MW in a single fundamental waveguide. This output structure consists of 12 individual cells, the first two incorporating de-Q-ing circuits to dampen higher order resonant modes. The second experiment studies the feasibility of enhancing beam to microwave power conversion by accelerating a modulated beam with induction cells. Referred to as the ''Reacceleration Experiment,'' this experiment consists of three traveling-wave output structures designed to produce about 125 MW per output and two induction cells located between the outputs. Status of current and planned experiments are presented

    The status of the experiment to search for a new gauge boson, A', in e+e- annihilation by means of a positron beam incident on a gas hydrogen target internal to the bypass at the VEPP-3 storage ring is reported. The search method is based on a missing mass spectra in reaction e+e- → γA'. It allows observation of the A' signal independently of its decay modes and life time. The projected result of this experiment corresponds to an upper limit on the square of coupling constant ε2 = (0.2 ÷ 1.0) · 10-7 with a signal-to-noise ratio of two to one at A' mass of 5–20 MeV.

    Home is a preferred place of death for many people; however, access to a home death may not be equitable. The impact of socioeconomic status on one's ability to die at home has been documented, yet there remains little literature exploring mechanisms that contribute to this disparity. By exploring the experiences and insights of physicians who provide end-of-life care in the home, this study aims to identify the factors perceived to influence patients' likelihood of home death and describe the mechanisms by which they interact with socioeconomic status. In this exploratory qualitative study, we conducted interviews with 9 physicians who provide home-based care at a specialized palliative care centre. Participants were asked about their experiences caring for patients at the end of life, focusing on factors believed to impact likelihood of home death with an emphasis on socioeconomic status, and opportunities for intervention. We relied on participants' perceptions of SES, rather than objective measures. We used an inductive content analysis to identify and describe factors that physicians perceive to influence a patient's likelihood of dying at home. Factors identified by physicians were organized into three categories: patient characteristics, physical environment and support network. Patient preference for home death was seen as a necessary factor. If this was established, participants suggested that having a strong support network to supplement professional care was critical to achieving home death. Finally, safe and sustainable housing were also felt to improve likelihood of home death. Higher SES was perceived to increase the likelihood of a desired home death by affording access to more resources within each of the categories. This included better health and health care understanding, a higher capacity for advocacy, a more stable home environment, and more caregiver support. SES was not perceived to be an isolated factor impacting likelihood of home death

    To answer the big trend of information disclosure, we are trying to report the experience and the current status of Radiotherapy in Teikyo University. Since 1974, Teikyo University has installed a High-Dose-Rate Remote Afterloading System (HDR RALS) at Itabashi Hospital for brachytherapy. We analyzed the total cases comprehensively in this paper. There were 421 cases treated by Ralstron (Shimazu Co.) between 1974 and 1995 and 128 cases treated additionally between the renewal by Microselectron (Nucletron Co.) and the end of 2002. For several years from the beginning, the number of cases treated by Ralstron had been 30-35 cases annually, but since 1987, the number decreased markedly to fewer than 10 cases per year. After the installation of Microselectron, the number increased gradually to 15 cases per year. Gynecologic tumors accounted for 88.5% of the total cases, namely 96.9% by Ralstron and 60.1% by Microselectron. The others treated by Microselectron were 27 cases with Head and Neck tumors, and 21 cases with digestive tract tumors. To increase the number of the patients for brachytherapy, we should continue to open our current status, and make close relationships between the neighbor hospitals and Teikyo Hospital. (author)

    CUORE is a 741 kg array of TeO2 bolometers for the search of neutrinoless double beta decay of 130Te. The detector is being constructed at the Laboratori Nazionali del Gran Sasso, Italy, where it will start taking data in 2015. If the target background of 0.01 counts / (keV ṡkg ṡy) will be reached, in five years of data taking CUORE will have a 1σ half life sensitivity of 1026 y. CUORE-0 is a smaller experiment constructed to test and demonstrate the performances expected for CUORE. The detector is a single tower of 52 CUORE-like bolometers that started taking data in spring 2013. The status and perspectives of CUORE will be discussed, and the first CUORE-0 data will be presented.

    The CAST experiment has been taking data since 2003 providing the most restrictive experimental limits on the axion-photon coupling for a broad range of rest mass. During 2012 the magnet cold bores were filled with He-4 for a new scan of axion masses around 0.4 eV in a theoretically motivated region of the parameter space. For the following two years CAST is planning to revisit the vacuum phase with enhanced sensitivity for axion searches but also lower detector threshold, which will allow to enter the new territory for solar WISPs in the sub-keV range, where also particles like chameleons are expected to appear. In this document we give the status report of 2012 run, and the physics motivation and running plans for 2013-2014.

    1989-09-01

    During 27-31 January 1986 the IAEA held a Technical Committee Meeting on ''Status, Experience, and Future Prospects for the Development of Probabilistic Safety Criteria''. Participation included representation of essentially all countries with major developments in the area as well as the Nuclear Energy Agency of the OECD and CEC. Though it has to be recognized that in such a short time period it is impossible to resolve or even analyse all aspects of this complex issue, the present situation, the main problems and the directions for future work clearly emerged. This report was prepared by the members of the Technical Committee based on the opinions expressed and on the information available at the time of the meeting. The report also contains 20 papers presented at the meeting by participants. A separate abstract was prepared for each of these 20 papers. Refs, figs and tabs

    The present status of the LOTUS project - a fusion-fission hybrid research facility under construction at the Ecole Polytechnique Federale de Lausanne (EPFL) Switzerland - is presented. Emphasis is places on the description of the facility and on the design studies of an initial blanket of the ''fission-suppressed'' type. The LOTUS facility consists of a parallelepiped-shaped blanket, occupying roughly a volume of 1 m 3 , driven by a sealed 14 MeV (D,T) neutron generator with a rated source strength of 5x10 12 n/s. The experiment is housed in a massive concrete shielding of 220 cm thick walls, which leaves an experimental test chamber of 360 cm by 240 cm lateral dimensions and a height of 300 cm. (orig.) [de

    Improvements in crop production depend on the correct adoption of agronomic and irrigation management strategies. The use of high spatial and temporal resolution monitoring methods may be used in precision agriculture to improve the efficiency in water and nutrient input management, guaranteeing the environmental sustainability of agricultural productions. In the last decades, many indices for the monitoring of water or nitrogen status of crops were developed by using multispectral images and, more recently, hyperspectral and thermal images acquired by satellite of airborne platforms. To date, however, comprehensive studies aimed at identifying indices as independent as possible for the management of the two types of stress are still scarce in the literature. Moreover, the chemometric approach for the statistical analysis of the acquired images is not yet widely experienced in this research area. In this context, this work presents the set-up of a greenhouse experiment that will start in February 2015 in Milan (Northern Italy), which aims to the objectives described above. The experiment will be carried out on two crops with a different canopy geometry (rice and spinach) subjected to four nitrogen treatments, for a total of 96 pots. Hyperspectral scanner and thermal images will be acquired at four phenological stages. At each phenological phase, acquisitions will be conducted on one-fourth of the pots, in the first instance in good water conditions and, subsequently, at different time steps after the cessation of irrigation. During the acquisitions, measurements of leaf area index and biomass, chlorophyll and nitrogen content in the plants, soil water content, stomatal conductance and leaf water potential will be performed. Moreover, on leaf samples, destructive biochemical analysis will be conducted to evaluate the physiological stress status of crops in the light of different irrigation and nutrient levels.

    Neutrinoless double beta decay is a lepton-number violating process predicted by many extensions of the standard model. It is actively searched for in several candidate isotopes within many experimental projects. The status of the experimental initiatives which are looking for the neutrinoless double beta decay in isotopes other than 136Xe is reviewed, with special emphasis given to the projects that passed the R&D phase. The results recently released by the experiment GERDA are also summarized and discussed. The GERDA data give no positive indication of neutrinoless double beta decay of 76Ge and disfavor in a model-independent way the long-standing observation claim on the same isotope. The lower limit reported by GERDA for the half-life of neutrinoless double beta decay of 76Ge is T1/20ν > 2.1 ṡ1025 yr (90% C.L.), or T1/20ν > 3.0 ṡ1025 yr, when combined with the results of other 76Ge predecessor experiments.

    The outcome of a probabilistic safety assessment (PSA) for a nuclear power plant is a combination of qualitative and quantitative results. Quantitative results are typically presented as the Core Damage Frequency (CDF) and as the frequency of an unacceptable radioactive release. In order to judge the acceptability of PSA results, criteria for the interpretation of results and the assessment of their acceptability need to be defined. Ultimately, the goals are intended to define an acceptable level of risk from the operation of a nuclear facility. However, safety goals usually have a dual function, i.e., they define an acceptable safety level, but they also have a wider and more general use as decision criteria. The exact levels of the safety goals differ between organisations and between different countries. There are also differences in the definition of the safety goal, and in the formal status of the goals, i.e., whether they are mandatory or not. In this first phase of the project, the aim has been on providing a clear description of the issue of probabilistic safety goals for nuclear power plants, to define and describe important concepts related to the definition and application of safety goals, and to describe experiences in Finland and Sweden. Based on a series of interviews and on literature reviews as well as on a limited international over-view, the project has described the history and current status of safety goals in Sweden and Finland, and elaborated on a number of issues, including the following: 1) The status of the safety goals in view of the fact that they have been exceeded for much of the time they have been in use, as well as the possible implications of these exceedances. 2) Safety goals as informal or mandatory limits. 3) Strategies for handling violations of safety goals, including various graded approaches, such as ALARP (As Low As Reasonably Practicable). 4) Relation between safety goals defined on different levels, e.g., for core damage

    Simons Array is a cosmic microwave background (CMB) polarization experiment located at 5,200 meter altitude site in the Atacama desert in Chile. The science goals of the Simons Array are to characterize the CMB B-mode signal from gravitational lensing, and search for B-mode polarization generated from inflationary gravitational waves.In 2012, POLARBEAR-1 (PB-1) began observations and the POLARBEAR team has published the first measurements of non-zero polarization B-mode polarization angular power spectrum where gravitational lensing of CMB is the dominant signal.POLARBEAR-2A (PB-2A), the first of three receivers of Simons Array, will have 7,588 polarization sensitive Transition Edge Sensor (TES) bolometers with frequencies 90 GHz and 150 GHz. This represents a factor of 6 increase in detector count compared to PB-1. Once Simons Array is fully deployed, the focal plane array will consist 22,764 TES bolometers across 90 GHz, 150 GHz, 220 GHz, and 270 GHz with a projected instantaneous sensitivity of 2.5 µK√s. Here we present the status of PB-2A and characterization of the integrated focal plane to be deployed summer of 2018.

    The AWAKE project at CERN is planned to study proton driven plasma wakefield acceleration with an externally injected electron beam. Therefore two transfer lines are being designed in order to provide the proton beam from the SPS and the electron beam from an RF gun to the plasma cell. The commissioning of the proton line will take place in 2016 for the first phase of the experiment, which is focused on the self-modulation of a 12 cm long proton bunch in the plasma. The electron line will be added for the second phase of AWAKE in 2017, when the wakefield will be probed with an electron beam of 10–20 MeV/c. The challenge for these transfer lines lies in the parallel operation of the proton, electron and laser beam used to ionize the plasma and seed the self-modulation. These beams, of different characteristics, need to be synchronized and positioned for optimized injection conditions into the wakefield. This task requires great flexibility in the transfer line optics. The status of these designs will be presented in this paper.

    In the framework of severe accident research on PWR, the Thema code aims at predicting the spreading extent of Corium in given conditions of pouring rate, initial Corium composition and temperature and considers phenomena as complex as top, bottom freezing and melting of the substrate. This paper makes the current status of the assessment of the code against the Corine experimental program which considers separate effect tests working out non freezing and low melting point simulating materials to validate some essential models present in spreading codes. Isothermal tests using water-glycerol mixtures are first considered to investigate the validity of the friction law and the extent of surface tension effects at the front. Non isothermal spreading with bottom freezing is then considered. Comparison of results of the code with known solutions of different problems related to solidification of a moving warm liquid, thermal chock and conduction in the bottom plate appears to be a very useful tool to verify the relevance of the models and to adjust numerical parameters. Finally, first spreading calculations with bottom freezing are compared with Corine experiments using the eutectic Bismuth-Tin alloy as working material. (author)

    Information disclosure is becoming a big trend these days, especially in the medical environment. To deal with the associated demands, the Department of Radiology, Teikyo University is continuing to report the experience and current status of radiotherapy. This report analyzed the total cases treated at Ichihara Hospital between the beginning of radiotherapy practice and the end of 2002. The basic items (age, sex, primary disease, primary organ, initial date of radiotherapy, initial department before radiotherapy, etc) of each case were studied. The accumulative numbers of the new patients and the overall treated patients were 1384 cases (278 from Surgery, 235 from Internal Medicine, 203 from Head and Neck (H and N), 143 from Ophthalmology, 134 from gynecology, etc) and 1795 cases (337 from Surgery, 321 from Internal Medicine, 271 from head and Neck (H and N), 180 from ophthalmology, 134 from Gynecology, etc) respectively. The sites of the primary lesions were 213 in digestive, 182 in respiratory, 171 in H and N, 159 in breast, 156 in central nervous system (CNS), 149 in hematologic, 131 in gynecologic, and 124 in urological organs. There are 60 cases of retinoblastoma in CNS tumors. It was thought that Ichihara Hospital of Teikyo University was very typical with regard to the patients referred to the Radiotherapy division. We will update this report periodically. (author)

    Female sexual behavior is sensitive to stress and diseases. Some studies have shown that status epilepticus (SE) can affect sexual proceptivity and receptivity in female rats and also increases reject responses towards males. However, epidemiologic studies indicate that SE is more frequent in young individuals. Herein, we assessed the effects of SE in infant females on their sexual behavior during adulthood. Thirteen-day-old (P13) rat pups received intraperitoneal injections of lithium chloride (3 mEq/kg). Twenty hours later, at P14, SE was induced by subcutaneous injection of pilocarpine hydrochloride (100 mg/kg s.c.). Control animals were given an equal volume of saline subcutaneously. The animals were weaned at P21 and, later in adulthood, were ovariectomized and hormone-primed with estradiol+progesterone, and their sexual behavior assessed during 4 separate trials of 30 min each with a stud male. Our results indicate that proceptive behaviors (solicitations and hops and darts) were impaired during the first trial, but no alterations were observed for receptivity and attractivity. By trial 3, all SE females displayed normal proceptivity. These results indicate that SE in infancy readily affects proceptivity in a reversible manner. We discuss the role of sexual experience in recovery. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available In this paper we inquire about the status of experience in the theory of knowledge of Pedro Figari (Uruguayan artist, philosopher and educator of the 20th Century to answer how his philosophy - of a monist characterization - influences his pedagogy - of an active orientation-. His monist, unicist or holistic construction, is the key to overcome the antagonism of dualistic positions and the mechanicism as a model for the dynamic of the being and the matter. His emblematic phrase, to work thinking  and to think  working, acts directly against what the dualism support, the mind-body separation, expressed and inscribed by Descartes as the pillars of the Enlightenment and the modernity, that is, establishing the division between episteme and doxa, the techné and the alienated action, factory-made. Arguments will be given to stay that the intervention of Figari´s philosophy and metaphysics, elaborated in his pedagogical thinking, is able to respond to issues that transcends their time, relevant to the current social reality.

    The discourse about mental health problems among migrants and refugees tends to focus on adverse pre-migration experiences; there is less investigation of the environmental conditions in which refugee migrants live, and the contrasts between these situations in different countries. This cross-national study of two samples of Somali refugees living in London (UK) and Minneapolis, Minnesota, (USA) helps to fill a gap in the literature, and is unusual in being able to compare information collected in the same way in two cities in different countries. There were two parts to the study, focus groups to gather in-depth qualitative data and a survey of health status and quantifiable demographic and material factors. Three of the focus groups involved nineteen Somali professionals and five groups included twenty-eight lay Somalis who were living in London and Minneapolis. The quantitative survey was done with 189 Somali respondents, also living in London and Minneapolis. We used the MINI International Neuropsychiatric Interview (MINI) to assess ICD-10 and DSM-IV mental disorders. The overall qualitative and quantitative results suggested that challenges to masculinity, thwarted aspirations, devalued refugee identity, unemployment, legal uncertainties and longer duration of stay in the host country account for poor psychological well-being and psychiatric disorders among this group. The use of a mixed-methods approach in this international study was essential since the quantitative and qualitative data provide different layers and depth of meaning and complement each other to provide a fuller picture of complex and multi-faceted life situations of refugees and asylum seekers. The comparison between the UK and US suggests that greater flexibility of access to labour markets for this refugee group might help to promote opportunities for better integration and mental well-being.

Coupled to a nuclear reactor, an S-I hydrogen plant could efficiently produce hydrogen without greenhouse gas emissions. In the S-I cycle, iodine and sulfur dioxide are combined with water to create two immiscible acid phases - a light sulfuric acid phase, and a heavy hydriodic acid phase. The sulfuric acid phase is decomposed at temperatures near 850 C degrees, and the resulting sulfur dioxide is recycled back into the process. The hydriodic acid in the lower phase is separated from excess water and iodine, and is then decomposed into the product hydrogen and iodine. The water and iodine from these steps are also recycled. In an International Nuclear Energy Research Initiative (INERI) project supported by the US DOE Office of Nuclear Energy, Sandia National Labs (SNL) has teamed with Cea in France, and industrial partner General Atomics (GA) to construct and operate a closed-loop device for demonstration of hydrogen production by the S-I process. Previous work in Japan has demonstrated continuous closed-loop operation of the S-I cycle for up to one week using glass components at atmospheric pressure. This work will aim for operation under process conditions expected at the pilot plant-level and beyond pressures up to 20 bar using engineering materials of construction. Staff at Cea is responsible for the acid-generation step, known as the Bunsen reaction. SNL is handling the sulfuric acid decomposition step, and GA is providing equipment for decomposing hydriodic acid into the product hydrogen. All parties are assembling equipment at the GA site in San Diego, California. Operation of the closed-loop device is expected to commence in the second half of calendar year 2007. This paper will summarize project goals, work done to date, current status, and scheduled future work on the INERI S-I Integrated-Loop Experiment. (authors)

    Sufficient recovery after daily effort expenditure at work is important to protect employee health and well-being. However, the role of commuting in the daily effort-recovery process is still not very well understood. The present study aimed to advance insight in this respect by examining if relaxation, detachment, mastery and stressful delays experienced during the commute from work to home affect employees' recovery status after returning home from work and at the end of the evening. Daily job demands were expected to moderate these effects. Serenity and (low) anxiety were included as indicators of employees' recovery status. Data were collected by means of a 5-day daily diary study (three measurements daily) among 76 participants from various industries. Multilevel analyses showed that relaxation was positively and stressful delays were negatively related to employees' recovery status after returning home from work but not to indicators of recovery at the end of the evening. For detachment, similar relations were found but only on days with high job demands. Mastery was not related to employees' recovery status. These findings enhance our insight in the daily effort-recovery cycle and underline the importance of promoting detachment (on demanding workdays) and relaxation on the way home from work.

    Following three decades, during which the Global Positioning System GPS has evolved from a military navigation system into an indispensable tool for geodetic research and global monitoring of the Earth, the world of satellite navigation has experienced dramatic changes over the past years. With GLONASS, a second global navigation system has achieved a fully operational status, GPS is introducing modernized civil and encrypted navigation signals, and a variety of new navigation constellations are being built-up in Asia and Europe. These include BeiDou, which has recently opened a regional navigation service in the Asia-Pacific region, Galileo, which now has four satellites in orbit, as well as QZSS, which offers a unique set of signals and service features. In recognition of a rapidly changing GNSS landscape, the International GNSS Service (IGS) has initiated the Multi-GNSS Experiment (MGEX - http://igs.org/mgex) as a platform for early familiarization with emerging navigation systems and to pave the way for a full-featured use thereof in a future multi-GNSS service. As a first step, MGEX has promoted the build-up of a new global network of GNSS monitoring stations, each tracking at least one new constellation (Galileo, BeiDou, or QZSS) on top of GPS, GLONASS and SBAS. By the end of 2012, approximately 50 stations contribute offline and/or real-time data to the MGEX network. To facilitate introduction of new standards (specifically RINEX3 observation and navigation data formats), distinct data archives are used even for those MGEX stations jointly contributing to the legacy IGS. Building-up on the new multi-GNSS network, the generation of associated orbit and clock products has started in the second quarter of 2012. At this stage, only Galileo and QZSS products are offered by selected MGEX Analysis Centers, but the addition of BeiDou is expected in 2013 as the MGEX network expands and new Analysis Centers join the data processing effort.

    The implementation of an internal quality control is mandatory to guarantee the accuracy of HER2 status in invasive breast cancers. To evaluate the impact of our quality control assurance on HER2 status results in invasive breast carcinomas from 2008 to 2014. HER2 status was determined by immunohistochemistry as the first-line indication, completed by fluorescence in situ hybridization (FISH) for scores 2+ by immunohistochemistry. Internal quality control of HER2 status relied on the standardization of pre-analytical phases, the use of external controls with a known number of HER2 gene copies determined by FISH and continued monitoring of concordance between immunohistochemistry and FISH. The proportion of HER2-positive cases corresponding to scores 3+ by immunohistochemistry and 2+ amplified by FISH varied from 10.6% to 13.8% (median of 11.3%). The proportion of scores 2+ amplified by FISH varied from 13.3% to 32.7% during period of study. The rate of concordance between FISH and immunohistochemistry for score 0/1+ and 3+ cases were≥97%. Eight among 12 discordant cases were false positive resulting from errors in interpretation of immunohistochemistry (score 2+ instead of 3+). Calibration of immunohistochemistry on FISH for HER2 status contributes to limit variability of immunohistochemistry results due to technical issues or interpretation. The implementation of an external control of score 3+ on each slide enables accurate interpretation of score 2+ and 3+ by immunohistochemistry. Copyright © 2017 Société Française du Cancer.

    In the Edelweiss experiment, nuclear recoils induced by elastic collisions with WIMPs (weakly interacting massive particle) from the galactic halo are identified in low-temperature Ge detectors where the ratio of the heat and ionization signals provide an event-by-event discrimination of nuclear recoils from the dominant background coming from {gamma}-rays interactions. The Edelweiss experiment is located in the Modane underground facility in order to cut the muon flux drastically. We present here the results obtained during the first part of the experiment named Edelweiss-I that ended in the beginning of 2004. Since october 2002, 3 optimized 320 grams detectors have been simultaneously operated at a regulated temperature of 0.017 K and about 50 kg*day were added to the previous published data. These data are still under analysis but preliminary results concerning the upper limit at 90% CL (confidence level) confirm the limit already published in 2002. The first run of Edelweiss-II is due to begin during summer 2005, we are expecting to gain 2 orders of magnitude in terms of detector sensitivity and reach 0.002 events/day*kg. (A.C.)

    We examined disparities in workers' occupational health experiences. We surveyed 941 unionized Las Vegas hotel room cleaners about their experiences with work-related pain and with employers, physicians, and workers' compensation. Data were analyzed for all workers and by ethnicity, language, and immigrant status. Hispanic and English as second language (ESL) workers were more likely than their counterparts to report work-related pain and, along with immigrant workers, to miss work because of this pain. Hispanic, ESL, and immigrant workers were not consistently at a disadvantage with regard to their own responses to work-related pain but were so with respect to reported responses by workers' compensation, physicians, and employers. There are indications of disparities in occupational health experiences within this job title. The use of different group classifications, while implying different mechanisms, produced similar results. © 2010 Wiley-Liss, Inc.

    2012-01-01

    One way to proof or exclude the existence of axion like particles is a microwave light shining through the wall experiment. In this publication we will emphasize on the engineering aspects of such a setup, currently under development at CERN. One critical point, to achieve meaningful results, is the electromagnetic shielding between axion-emitter and -receiver cavity, which needs to be in the order of 300 dB to improve over existing experimental bounds. The RF leakage or electromagnetic crosstalk between both cavities must be well controlled and quantified during the complete duration of the experiment. A very narrow band (in the 10^-6 Hz range) homodyne detection method is used to reveal the axion signal from background thermal noise. The current status of the experiment is presented.

    Morocco has become a permanent transit country for tens of thousands of sub-Saharan migrants heading to Europe. Many of these migrants are women who have a precarious legal status and can no longer reach Europe, whose borders have been considerably securitized since September 11, 2001. They also have no wish to risk their lives again returning south across the Sahara Desert. This paper discusses the results of an exploratory research project conducted in Morocco on the relationships between the sub-Saharan migrant women's traumatic experiences, social invisibility, and emotional distress in the context of a massive securitization of Euro-Mediterranean borders.

    The design and operational experience with the first controlled Exo-Brake system flown during March, 2017, as conducted by the NASA Ames Research Center, is described. The Exo-Brake is an exo atmospheric braking and de-orbit device which had successfully flown twice before in a fixed-drag configuration on the nano-sat orbital platforms TechEdSat-3,4. The TechEdSat-5 flight, was the first to permit a commanded shape change which affected the drag (thus, ballistic coefficient), and thus allowed improved targeting. The use of the Iridium constellation and on-board Short Burst Data (SBD) modems, as well as Global Positioning Systems (GPS), permitted daily updates to be performed. This allowed compensation for the Thermosphere density variations captured in the F10.7 variable.Current and highly detailed analysis based on Monte-Carlo techniques suggest that approx. 7 modulations can achieve a relatively small Brake systems may be used for more accurate nano-sat or small-sat disposal - or the development of technologies to permit on-demand sample return from Low Earth Orbit (LEO) scientific/manufacturing platforms.

    Psychotic-like experiences (PLEs) are considered predictive of mental health problems later in life. However, little has been known about the mental health status and psychopathological distress in adolescents with PLEs in the general population. To investigate the associations between PLEs and mental health status or psychopathologies in a community sample of adolescents in a school-based cross-sectional fashion, PLEs were studied using a self-rating questionnaire in 5073 Japanese junior-high school students aged 12-15 years. Mental health status was evaluated using the 12-item General Health Questionnaire (GHQ-12). Psychopathologies, lifestyle, victimization, and interpersonal and help-seeking attitudes were also studied using a self-rating questionnaire. Fifteen percent of the students reported definitely having experienced at least one PLE. A dose-response relationship between the severity of PLEs and the prevalence of poor mental health status was observed. PLEs were also significantly associated with psychopathologies (strong anxiety in the classroom: OR = 1.4, 95% CI 1.2-1.6; suicidal ideation: OR = 2.1, 95% CI 1.8-2.4; self-harm behaviors: OR = 1.4, 95% CI 1.0-1.9; difficulty falling asleep due to hypersensitivity to environmental noise: OR = 1.7, 95% CI 1.4-2.0; difficulty concentrating due to hypersensitivity to environmental noise: OR = 1.5, 95% CI 1.3-1.8; physically assaulting others: OR = 1.3, 95% CI 1.0-1.5; bullying others, OR = 1.3, 95% CI 1.1-1.5; irritability when exchanging e-mails: OR = 1.3, 95% CI 1.0-1.6). Adolescents with PLEs in the community suffer from a wide range of psychopathological problems during crucial developmental periods [corrected

    2015-08-01

    The GERDA experiment is designed to search for neutrinoless double beta decay of 76Ge using HPGe detectors directly immersed into liquid argon. In its first phase the GERDA experiment has yielded a half life limit on this decay of T1/2 0 v>2.1 ṡ1025 . A background model has been developed. It explains the measured spectrum well, taking into account only components with distances to the detectors less then 2 cm. Competitive limits on Majoron accompanied double beta decay have been derived. Phase II of the experiment, now with additional liquid argon veto installed, is presently starting its commissioning phase. First commissioning spectra from calibration measurements are shown, proving that the liquid argon veto leads to a significant reduction of background events.

    2006-10-22

    One of the unanswered and most fundamental questions in physics regards the nature of the confinement mechanism of quarks and gluons in QCD. Exotic hybrid mesons manifest gluonic degrees of freedom and their spectroscopy will provide the data necessary to test assumptions in lattice QCD and the specific phenomenology leading to confinement. Within the past two decades a number of experiments have put forth tantalizing evidence for the existence of exotic hybrid mesons in the mass range below 2 GeV. This talk represents an overview of the available data and what has been learned. In looking toward the future, the GlueX experiment at Jefferson Laboratory represents a new initiative that will perform detailed spectroscopy of the light-quark meson spectrum. This experiment and its capabilities will be reviewed.

    The radiofrequency ion thruster assembly (RITA) is currently built as a flight experiment which shall be flown on the European retrievable carrier (Eureca I). This test flight shall verify the operational use of this electric propulsion system in space by demonstration of operation, lifetime and reliability. For this purpose the RITA experiment has been adapted to meet the specific constraints imposed by the Eureca I spacecraft and by the Space Shuttle as the launcher; xenon gas will be used as the propellant and the experiment will be operated automatically by means of a dedicated on-board microcomputer system. According to the delay in launches by the Space Shuttle the launch date has been postponed from March 1988 to 1991/92. Therefore the total Eureca program has been extended, which also influenced the RITA time schedule.

    Despite widespread efforts to expand health insurance in developing countries, there is scant evidence as to whether doing so actually improves people's health. This paper aims to fill this gap by evaluating the impact of Rural Mutual Health Care (RMHC), a community-based health insurance scheme, on enrollees' health outcomes. RMHC is a social experiment that was conducted in one of China's western provinces from 2003 to 2006. The RMHC experiment adopted a pre-post treatment-control study design. This study used panel data collected in 2002, 1 year prior to the intervention, and followed up in 2005, 2 years after the intervention, both in the intervention and control sites. We measured health status using both a 5-point Categorical Rating Scale and the EQ-5D instruments. The estimation method used here is difference-in-difference combined propensity score matching. The results show that RMHC has a positive effect on the health status of participants. Among the five dimensions of EQ-5D, RMHC significantly reduces pain/discomfort and anxiety/depression for the general population, and has a positive impact on mobility and usual activity for those over 55-years old. Our study provides useful policy information on the development of health insurance in developing countries, and also identifies areas where further research is needed.

    The National Criticality Experiments Research Center (NCERC) was officially opened on August 29, 2011. Located within the Device Assembly Facility (DAF) at the Nevada National Security Site (NNSS), the NCERC has become a consolidation facility within the United States for critical configuration testing, particularly those involving highly enriched uranium (HEU). The DAF is a Department of Energy (DOE) owned facility that is operated by the National Nuclear Security Agency/Nevada Site Office (NNSA/NSO). User laboratories include the Lawrence Livermore National Laboratory (LLNL) and Los Alamos National Laboratory (LANL). Personnel bring their home lab qualifications and procedures with them to the DAF, such that non-site specific training need not be repeated to conduct work at DAF. The NNSS Management and Operating contractor is National Security Technologies, LLC (NSTec) and the NNSS Safeguards and Security contractor is Wackenhut Services. The complete report provides an overview and status of the available laboratories and test bays at NCERC, available test materials and test support configurations, and test requirements and limitations for performing sub-critical and critical tests. The current summary provides a brief summary of the facility status and the method by which experiments may be introduced to NCERC.

    The COOL project provides common software components and tools for the handling of the conditions data of the LHC experiments. It is part of the LCG Persistency Framework (PF), a broader project set up within the context of the LCG Application Area (AA) to devise common persistency solutions for the LHC experiments. COOL software development is the result of the collaboration between the CERN IT Department and ATLAS and LHCb, the two experiments that have chosen it as the basis of their conditions database infrastructure. COOL supports conditions data persistency using several relational technologies (Oracle, MySQL, SQLite and FroNTier), based on the CORAL Common Relational Abstraction Layer. For both experiments, Oracle is the backend used for the deployment of COOL database services at Tier0 and Tier1 sites of the LHC Computing Grid. While the development of new software functionalities is being frozen as LHC operations are ramping up, the main focus for the project in 2008 has shifted to performance optimi...

    2016-11-01

    The Muon g-2 Experiment at Fermilab will measure the anomalous magnetic moment of the muon to a precision of 140 parts per billion, which is a factor of four improvement over the previous E821 measurement at Brookhaven. The experiment will also extend the search for the electric dipole moment (EDM) of the muon by approximately two orders of magnitude, with a sensitivity down to 10-21 e.cm. Both of these measurements are made by combining a precise measurement of the 1.45T storage ring magnetic field with an analysis of the modulation of the decay rate of higher-energy positrons (from anti-muons), recorded by 24 calorimeters and 3 straw tracking detectors. The recent progress in the alignment of the electrostatic quadrapole plates and the trolley rails inside the vacuum chambers, and in establishing the uniform storage ring magnetic field will be described.

    Full Text Available The Germanium Detector Array (Gerda is a low background experiment at the Laboratori Nazionali del Gran Sasso (LNGS of the INFN designed to search for the rare neutrinoless double beta decay (0νββ of 76Ge. In its first phase, high purity germanium diodes inherited from the former Heidelberg-Moscow and Igex experiments are operated “bare” and immersed in liquid argon, with an overall background environment of 10−2 cts/(keV·kg·yr, a factor of ten better than its predecessors. Measurements on two-neutrino double beta decay (2νββ giving T1/22ν=(1.88±0.10×1021 yr and recently published background model and pulse shape performances of the detectors are discussed in the paper. A new result on 0νββ has been recently published with a half-life limit on 0νββ decay T1/20ν>2.1×1025 yr (90% C.L.. A second phase of the experiment is scheduled to start during the year 2014, after a major upgrade shutdown. Thanks to the increased detector mass with new designed diodes and to the introduction of liquid argon instrumentation techniques, the experiment aims to reduce further the expected background to about 10−3 cts/(keV·kg·yr and to improve the 0νββ sensitivity to about T1/20ν>1.5×1026 yr (90% C.L..

    In the quest to demonstrate Inertial Confinement Fusion (ICF) ignition of deuterium-tritium (DT) filled capsules and propagating thermonuclear burn with net energy gain (fusion energy/laser energy >1), recent experiments on the National Ignition Facility (NIF) have shown progress towards increasing capsule hot spot temperature (T ion >5 keV) and fusion neutron yield (~10 16 ), while achieving ~2x yield amplification by alpha particle deposition. At the same time a performance cliff was reached, resulting in lower fusion yields than expected as the implosion velocity was increased. Ongoing studies of the hohlraum and capsule physics are attempting to disseminate possible causes for this performance ceiling.

    The German National Analysis Facility (NAF) was set up at DESY, starting end of 2007 in the context of the Helmholtz Alliance "Physics at the Terascale". The NAF complements the DESY and the German Grid resources, and hence offers users from the German HEP institutes the best possible environment for data analysis. In the first part, the key aspects and components of the NAF are briefly presented with an emphasis on recent improvements. In the second part, the use cases of the three participating LHC experiments, ATLAS, CMS and LHCb, will be presented. Differences and commonalities in the usage of the NAF will be shown. Special emphasis will be placed on the usage of PROOF, whose usage on the NAF has been pioneered by CMS. It is now adapted by ATLAS. The third part will concentrate on how the NAF was used for detector optimisation studies in the preparation of one of the ILC Lol's (ILD 2009), as well as how CALICE uses the NAF for the analysis of their data taken in several test beam experiments performed for detector R & D. Finally, future developments of the NAF are presented.

    Azechi, H.; Fujimoto, Y.; Fujioka, S.

    2012-11-01

    Controlled thermonuclear ignition and subsequent burn will be demonstrated in a couple of years on the central ignition scheme. Fast ignition has the high potential to ignite a fuel using only about one tenth of laser energy necessary to the central ignition. This compactness may largely accelerate inertial fusion energy development. One of the most advanced fast ignition programs is the Fast Ignition Realization Experiment (FIREX). The goal of its first phase is to demonstrate ignition temperature of 5 keV, followed by the second phase to demonstrate ignition-and-burn. The second series experiment of FIREX-I from late 2010 to early 2011 has demonstrated a high (≈20%) coupling efficiency from laser to thermal energy of the compressed core, suggesting that one can achieve the ignition temperature at the laser energy below 10 kJ. Given the demonstrations of the ignition temperature at FIREX-I and the ignition-and-burn at the National Ignition Facility, the inertial fusion research would then shift from the plasma physics era to power generation era.

    This study aims to understand the migratory experience and the employment, work and health conditions of the returned migrants from Spain to Colombia. A qualitative study was conducted by means of 23 semi-structured interviews with Colombian returned migrant workers. Qualitative narrative content analysis was performed using Atlas.Ti software. Main findings are represented by nine categories emerged from the participants' discourses: (1) impact of the economic crisis on work and employment conditions in Spain, (2) economic crisis and return, (3) characteristics of returnees, (4) perception of the returnees about Colombia, (5) the role of social support networks, (6) employment and working conditions in Colombia, (7) health and wellbeing, (8) future plans and expectations, (9) the experience of being immigrant. Adjustment difficulties in participants are evidenced by the return migration process and the conditions of the social, political and economic system in Colombia. Return migration represents the reconfiguration of personal and working lives of this population. This situation requires the development of global policies and strategies in public health to facilitate the adaptation of these people.

    Background: according to ISTAT (National Institute of Statistics-Italy, in 2011 20.7% of the foreign population in Italy is composed by children, either coming along with their families or alone, like in international adoptions. Immigrant children have some peculiarities related to their previous living conditions, although there are no significant differences between immigrant and native children’ diseases.

    Methods: in 3.5 years we evaluated every adoptee that reached our university centre, by using GLNBI (Gruppo di Lavoro Nazionale del Bambino Immigrato diagnostic – aiding protocol, in order to assess infectious diseases, nutritional deficiencies, immunization status, intestinal parasitosis or other pathologies; this protocol is actually applied only in research centres.

    Results: we evaluated 358 international adoptees from 4 different Zones of the world; average age at first visit was approximately 5 years. Health certifications concerning vaccination history records were considered “valid” in 59.2% (212/358, 49.5% (105/212 of which had a complete panel of immunization. QuantiFERON®_TB Gold In-Tube (QTF test resulted negative in 94.0% cases (313/333 and positive in 6.0% (20/333. HIV, HCV and Syphilis tests resulted in 0.3% positive test for each serology (1/358. Cysticercosis’ serology was positive in 8.9% (32/358 using immunoenzymatic assay (not confirmed by immunoblotting and Toxocariasis in 13.1% (47/358. Parasitological investigation of faeces were found positive on 42.7% (153/358 children, throat swabs in 11.5% (41/358 children. There were 82.4% (295/358 abnormal blood count, 41.9% (150/358 low ferritin, 89.9% (322/358 endocrine abnormalities and 20.4% (73/358 various pathologies evaluated by specialists.

    Conclusions: pathologies affecting our study group are the same affecting other categories of immigrant children, because they often

    Development of fluoride-salt-cooled, high-temperature reactor (FHR) technology requires a better understanding of key hydrodynamic and heat transfer phenomena associated with this novel class of reactors. The use of simulant fluids that can match the most important non dimensional numbers between scaled experiments and prototypical FHR systems enables integral effects tests (IETs) to be performed at reduced cost and difficulty for FHR code validation. The University of California at Berkeley (UCB) and the University of New Mexico (UNM) have built a number of IETs and separate effects tests to investigate pebble-bed FHR (PB-FHR) phenomenology using water or simulant oils such as Dowtherm A. PB-FHR pebble motion and porous media flow dynamics have been investigated with UCB's pebble recirculation experiments using water and plastic spheres. Transient flow of high-Prandtl-number fluids around hot spheres has also been investigated by UCB to measure Nusselt numbers in pebble-bed cores, using simulant oils and copper spheres. Finally, single-phase forced/natural circulation has been investigated using the scaled height, reduced flow area loops of the Compact Integral Effects Test facility at UCB and a multi-flow regime loop at UNM, using Dowtherm A oil. The scaling methodology and status of these ongoing experiments are described here

    2013-04-01

    The overarching objective of integrated hydrologic ground validation activities supporting the Global Precipitation Measurement Mission (GPM) is to provide better understanding of the strengths and limitations of the satellite products, in the context of hydrologic applications. To this end, the GPM Ground Validation (GV) program is conducting the first of several hydrology-oriented field efforts: the Iowa Flood Studies (IFloodS) experiment. IFloodS will be conducted in the central to northeastern part of Iowa in Midwestern United States during the months of April-June, 2013. Specific science objectives and related goals for the IFloodS experiment can be summarized as follows: 1. Quantify the physical characteristics and space/time variability of rain (rates, DSD, process/"regime") and map to satellite rainfall retrieval uncertainty. 2. Assess satellite rainfall retrieval uncertainties at instantaneous to daily time scales and evaluate propagation/impact of uncertainty in flood-prediction. 3. Assess hydrologic predictive skill as a function of space/time scales, basin morphology, and land use/cover. 4. Discern the relative roles of rainfall quantities such as rate and accumulation as compared to other factors (e.g. transport of water in the drainage network) in flood genesis. 5. Refine approaches to "integrated hydrologic GV" concept based on IFloodS experiences and apply to future GPM Integrated GV field efforts. These objectives will be achieved via the deployment of the NASA NPOL S-band and D3R Ka/Ku-band dual-polarimetric radars, University of Iowa X-band dual-polarimetric radars, a large network of paired rain gauge platforms with attendant soil moisture and temperature probes, a large network of both 2D Video and Parsivel disdrometers, and USDA-ARS gauge and soil-moisture measurements (in collaboration with the NASA SMAP mission). The aforementioned measurements will be used to complement existing operational WSR-88D S-band polarimetric radar measurements

    Cosmic ray events with rate and energy much higher than expected were detected by the ultracryogenic gravitational antenna Nautilus located at the Laboratori Nazionali di Frascati, when it was operating in superconducting state. Mechanisms related to the superconductivity state of the material could be involved in such a way to enhance the conversion efficiency of the particle energy into vibrational energy of the detector. The RAP experiment has the aim to study the mechanical response of a small metallic resonant bar to short pulses of high energy electron beam, investigating the response of the bar both in normal and in superconducting state. The results obtained for an Al5056 bar down to a temperature of 4 K are reported and the preliminary results for a niobium bar at temperature below and above the superconducting-normal transition are also discussed

  9. The status of the solar neutrino problem and the Russian-American gallium experiment (SAGE)

    International Nuclear Information System (INIS)

    Bowles, T.J.

    1994-01-01

    Perhaps the most outstanding discrepancy between prediction and measurements in current particle physics comes from the solar neutrino problem, in which a large deficit of high-energy solar neutrinos is observed. Many Nonstandard Solar Models have been invoked to try to reduce the predicted flux, but all have run into problems in trying to reproduce other measured parameters (e.g., the luminosity) of the Sun. Other explanations involving new physics such as neutrino decay and neutrino oscillations, etc. have also been proffered. Again, most of these explanations have been ruled out by either laboratory or astrophysical measurements. It appears that perhaps the most likely particle physics solution is that of matter enhanced neutrino oscillation, the Mikheyev-Smirnov-Wolfenstein (MSW) oscillations. Two new radiochemical gallium experiments, which have a low enough threshold to be sensitive to the dominant flux of low-energy p-p neutrinos, now also report a deficit and also favor a particle physics solution

    2014-01-01

    The paper deals with practice and performance of postal TLD audits in radiotherapy with emphasis on the possibilities of application of the advanced versions that were developed following up technological progress in radiotherapy. The new methodologies of the TLD audit are focused specifically on up-to-date linear accelerators, equipped with multileaf collimators, and modern treatment planning systems. The dose is checked by the TLD not only for reference conditions but also in conditions of radiation fields influenced by presence of inhomogeneities in the irradiated volume. As regards small radiation fields, the check also includes dose profile verification using gafchromic films. The methodologies were tested within pilot studies performed in collaboration with some Czech radiotherapy centers. The results and experience gave evidence of the usefulness and appropriateness of the new TLD audit methodologies. (orig.)

    The LEAR experiment PS170 is designed to detect the e +- pairs from anti p-annihilation. It aims to measure the proton form factors in the time like region and the spectrum of vector mesons in the mass range: 1-1,6 GeV. Data have been taken at 300, 600 and 1500 MeV/c incident momenta. The analysis of the 300 MeV/c data gave 200 2-body events: (anti pp → e + e - ), clearly separated from the hadronic background. Values of the form factors are extracted near threshold. The next step will be to accumulate sufficient data to measure separately the electric and magnetic components up to 600 MeV/c. The use of an internal target is considered for measurements at high momenta

    The purpose of this study was to assess functional changes in the cerebral cortex in people with different sign language experience and hearing status whilst observing and imitating Chinese Sign Language (CSL) using functional magnetic resonance imaging (fMRI). 50 participants took part in the study, and were divided into four groups according to their hearing status and experience of using sign language: prelingual deafness signer group (PDS), normal hearing non-signer group (HnS), native signer group with normal hearing (HNS), and acquired signer group with normal hearing (HLS). fMRI images were scanned from all subjects when they performed block-designed tasks that involved observing and imitating sign language stimuli. Nine activation areas were found in response to undertaking either observation or imitation CSL tasks and three activated areas were found only when undertaking the imitation task. Of those, the PDS group had significantly greater activation areas in terms of the cluster size of the activated voxels in the bilateral superior parietal lobule, cuneate lobe and lingual gyrus in response to undertaking either the observation or the imitation CSL task than the HnS, HNS and HLS groups. The PDS group also showed significantly greater activation in the bilateral inferior frontal gyrus which was also found in the HNS or the HLS groups but not in the HnS group. This indicates that deaf signers have better sign language proficiency, because they engage more actively with the phonetic and semantic elements. In addition, the activations of the bilateral superior temporal gyrus and inferior parietal lobule were only found in the PDS group and HNS group, and not in the other two groups, which indicates that the area for sign language processing appears to be sensitive to the age of language acquisition. After reading this article, readers will be able to: discuss the relationship between sign language and its neural mechanisms. Copyright © 2014 Elsevier Inc

    The Insight NASA Discovery mission, led by the Jet Propulsion Laboratory, will deploy in September 2016 a very broadband seismometer on the Mars surface, SEIS (Seismic Experiment for Interior Structure). It is a hybrid 3-axes instrument, which encloses 3 very broadband oblique sensors and 3 short period sensors. The sensor assembly and its wind and thermal shield will by deployed on the Mars surface from the Phoenix-like spacecraft by a robotic arm (IDS). The acquisition system will be hosted in the spacecraft warm electronics box, and connected to the deployed sensor assembly by a tether. The SEIS experiment is provided by CNES, the French Space Agency that makes the coordination of a wide consortium including IPGP of Paris (SEIS PI Institution), Imperial College of London, Oxford University, MPS of Göttingen, ETH of Zürich, ISAE from Toulouse and the Jet Propulsion Laboratory of Pasadena. In addition to the seismometer, the Insight payload will also include a suite of instruments complementary to the seismometer, such as a precision temperature sensor, a micro-barometer, a magnetometer and a wind sensor, making it the first geophysical multi-parameter station on another planet. A heat flow sensor and geodetic measurements will provide additional science measurements, in order to constrain the internal structure of Mars. Several challenges have been overcome to design and realize the planetary seismometer, which will exhibit a noise of about 10-9 m/s2/sqrt(Hz) in its seismic bandwidth bandwidth (0.01-1 Hz) for the very broadband component. These challenges include a very efficient insulation from the external temperature variations, and a finely crafted mechanical design to keep the extreme sensitivity of the seismometer, while allowing enough robustness for the harsh mechanical environment encountered during the launch and landing sequences. Also, specific attention has been paid to understanding the various environment contributions to the noise figure. A

    Study of the ultra-rare K → πν(bar ν) decays is highly motivated by their unique theoretical access to short distance physics allowing deep probing of physics beyond the Standard Model including possible new sources of CP violation and flavor symmetry breaking. It also appears that through the development of targeted experimental techniques, both the charged and neutral processes, K + → π + ν(bar ν) and K L 0 → π 0 ν(bar ν), are accessible to detailed measurement. Three events consistent with K + → π + ν(bar ν) decay have been observed by BNL E787/E949 and further measurements of this reaction are being planned. The new KOPIO experiment at BNL is aiming to study the special CP-violating decay K L 0 → π 0 ν(bar ν) with a precision of 10%. The motivations, experimental methods, prospects, and possible impact of KOPIO and other future measurements will be discussed.

    The GRAPES-3 is a dense extensive air shower array operating with ∼400 scintillator detectors and it also contains a 560 m 2 tracking muon detector (E μ >1GeV), at Ooty in India. 25% of scintillator detectors are instrumented with two fast photomultiplier tubes (PMTs) for extending the dynamic range to ∼5x10 3 particles m -2 . The scintillators, signal processing electronics and data recording systems were fabricated in-house to cut costs and optimize performance. The muon multiplicity distribution of the EAS is used to probe the composition of primary cosmic rays below the 'knee', with an overlap with direct measurements. Search for multi-TeV γ-rays from point sources is done with the aid of the muon detector. A good angular resolution of 0.7 deg. at 30 TeV, is measured from the shadow of the Moon on the isotropic flux of cosmic rays. A sensitive limit on the diffuse flux of 100 TeV γ-rays is placed by using muon detector to filter the charged cosmic ray background. A tracking muon detector allows sensitive measurements on coronal mass ejections and solar flares through Forbush decrease events. We have major expansion plans to enhance the sensitivity of the GRAPES-3 experiment in the areas listed above.

    It is important to measure the cosmic ray spectra to study the origin, acceleration and propagation mechanisms of high-energy cosmic rays. A payload of the Cosmic Ray Energetics And Mass experiment is scheduled to be launched in 2017 to the International Space Station for measuring cosmic ray elemental spectra at energies beyond the reach of balloon instruments. Top Counting Detector and Bottom Counting Detector (T/BCD) as a two-dimensional detector are to separate electrons from protons for electron/gamma-ray physics. The T/BCD each consists of a plastic scintillator read out by 20 by 20 photodiodes and is placed before and after the Calorimeter, respectively. Energy and hit information of the T/BCD can distinguish shower profiles of electrons and protons, which show narrower and shorter showers from electrons at a given energy. The T/BCD performance has been studied with the Silicon Charge Detector and the calorimeter by using a GEANT3 + FLUKA 3.21 simulation package. By comparing the number of hits and shower width distributions between electrons and protons, we have studied optimal parameters for the e/p separation.

    Crystal channeling technology has offered various opportunities in the accelerator community with a viability of ultrahigh gradient (TV/m) acceleration for future HEP collider. The major challenge of channeling acceleration is that ultimate acceleration gradients might require a high power driver in the hard x-ray regime (~ 40 keV). This x-ray energy exceeds those for x-rays as of today, although x-ray lasers can efficiently excite solid plasma and accelerate particles inside a crystal channel. Moreover, only disposable crystal accelerators are possible at such high externally excited fields which would exceed the ionization thresholds destroying the atomic structure, so acceleration will take place only in a short time before full dissociation of the lattice. Carbon-based nanostructures have great potential with a wide range of flexibility and superior physical strength, which can be applied to channeling acceleration. This paper presents a beam- driven channeling acceleration concept with CNTs and discusses feasible experiments with the Advanced Superconducting Test Accelerator (ASTA) in Fermilab.

    To ascertain the impact of therapy on gonadal function and reproductive outcome among children treated for Hodgkin's disease, we reviewed the experience at Stanford University Medical Center during the years 1965-1986. There were 240 children 15 years of age or younger, 92 girls and 148 boys; with median follow-up of 9 years, maximum follow-up was 26 years. Of this cohort, data on gonadal function were available on 20 boys, 5 of whom were considered prepubescent; they had no clinical evidence of sexual maturation and were less than 13 years of age. Evaluation of the boys included testicular biopsy, semen analyses and the ability to procreate. Serum gonadotropin hormone levels (FSH, LH) were studied in 11 boys who also had semen analyses. Sexual maturation was attained in all boys without the need for androgen replacement. Among the eight boys treated with radiation alone, four were able to father a child (3 following 40-45 Gy pelvic radiation dose, 1 without pelvic radiation) from 3-19 years following treatment. Three others who received 30-44 Gy pelvic radiation were oligospermic when tested at 10 to 15 years post-treatment. Semen analyses in 10 of 12 (83%) boys who had been treated with six cycles of MOPP with or without pelvic radiation revealed absolute azoospermia with no evidence of recovery as along as 11 years of follow-up. Following prolonged azoospermia, 2 of the 12 boys (17%) had recovery of fertility, with normalization of sperm count and/or ability to procreate at 12 and 15 years following treatment. There was no correlation with serum gonadotropin levels and sterility. Data on menstrual history, pregnancy and offspring were available in 86 (92%) of the girls. Seventy-five of the 86 girls (87%) have normal menstrual function. However, none of the females who underwent pelvic radiation without prior oophoropexy has maintained ovarian function

    Highlights: ► The trim coil system will fine tune the main magnetic field during plasma operation by reducing the magnetic field errors. ► The coil design and operational parameters are fixed, the manufacturing is running. ► The coils are equipped with temperature sensors and a voltage tap system to monitor the coil temperature. ► The max. operational deflection is in the order of 4.5 mm; the max. shearing stress across bond planes is of order 16 MPa. ► Special clamps equipped with elastomeric pads allow fixing the coils on the outer cryostat wall. -- Abstract: The stellarator fusion experiment Wendelstein 7-X (W7-X) is currently under construction at the Max-Planck-Institut für Plasmaphysik in Greifswald, Germany. The main magnetic field will be provided by a superconducting magnet system which generates a fivefold toroidal periodic magnetic field. However, unavoidable tolerances can result in small deviations of the magnetic field which disturb the toroidal periodicity. In order to have a tool to influence these field errors five additional normal conducting trim coils were designed to allow fine tuning of the main magnetic field during plasma operation. In the frame of an international cooperation the trim coils will be contributed by the US partners. Princeton Plasma Physics Laboratory has accomplished several tasks to develop the final design ready for manufacturing e.g. detailed manufacturing design for the winding and for the coil connection area. The design work was accompanied by a detailed analysis of resulting forces and moments to prove the design. The manufacturing of the coils is running at Everson Tesla Inc; the first two coils were received at IPP.

    Objective To examine health status and health care experiences of homeless patients in health centers and to compare them with their nonhomeless counterparts. Data Sources/Study Setting Nationally representative data from the 2009 Health Center Patient Survey. Study Design Cross-sectional analyses were limited to adults (n = 2,683). We compared sociodemographic characteristics, health conditions, access to health care, and utilization of services among homeless and nonhomeless patients. We also examined the independent effect of homelessness on health care access and utilization, as well as factors that influenced homeless patients' health care experiences. Data Collection Computer-assisted personal interviews were conducted with health center patients. Principal Findings Homeless patients had worse health status—lifetime burden of chronic conditions, mental health problems, and substance use problems—compared with housed respondents. In adjusted analyses, homeless patients had twice the odds as housed patients of having unmet medical care needs in the past year (OR = 1.98, 95 percent CI: 1.24–3.16) and twice the odds of having an ED visit in the past year (OR = 2.00, 95 percent CI: 1.37–2.92). Conclusions There is an ongoing need to focus on the health issues that disproportionately affect homeless populations. Among health center patients, homelessness is an independent risk factor for unmet medical needs and ED use. PMID:23134588

    Despite burgeoning evidence linking early exposure to child maltreatment (CM) to deficits in self-regulation, the pathways to strong regulatory development in these children are not well understood, and significant heterogeneity is observed in their outcomes. Experiences of autonomy may play a key role in transmitting self-regulatory capacity across generations and help explain individual differences in maltreatment outcomes. In this study, we investigated multigenerational associations between Generation 1 (G1)-Generation 2 (G2) mothers' early experience of warmth and autonomy in relation to their own mothers and their Generation 3 (G3) children's autonomic physiological regulation in CM (n = 85) and non-CM (n = 128) families. We found that G2 mothers who recalled greater autonomy in their childhood relationship with their G1 mothers had preschool-age G3 children with higher respiratory sinus arrhythmia at baseline when alone while engaged in individual challenge tasks, during social exchanges with their mother in joint challenge tasks, and during the portions of the strange situation procedure when the mother was present. Although no clear mediators of this association emerged, multigenerational links among G1-G2 relations, maternal representations of her child, child behavior, and child respiratory sinus arrhythmia differed by maltreatment status, thus possibly representing important targets for future research and intervention.

    This study aimed to quantify the extent to which socioeconomic-related inequality in self-reported oral health status among Thais is present after the country implemented the Universal Coverage policy and to decompose the determinants and their associations with inequality in self-reported oral health status in particular with the worse condition. The study employed a concentration index to measure socioeconomic-related inequality in self-reported oral health status, and the decomposition method to identify the determinants and their associations with inequality in oral health-related measures. Data from 32,748 Thai adults aged 15-75 years from the nationally representative Health &Welfare Survey and Socio-Economic Survey 2006 were used in analyses. Reports of worse oral health status of the lower socioeconomic-status group were more common than their higher socioeconomic-status counterparts. The concentration index (equaling -0.208) corroborates the finding of pro-poor inequality in self-reported worse oral health. Decomposition analysis demonstrated certain demographic-, socioeconomic-, and geographic characteristics are particularly associated with poor-rich differences in self-reported oral health status among Thai adults. This study demonstrated socioeconomic-related inequality in oral health is discernable along the entire spectrum of socioeconomic status. Inequality in perceived oral health status among Thais is present even while the country has virtually achieved universality of health coverage. The study also indicates population subgroups, particularly the poor, should receive consideration for improving oral health status as revealed by underlying determinants.

    Individuals exposed to adverse childhood experiences (ACEs) are vulnerable to various health problems later in life. This study was designed to determine whether participation in an efficacious program to enhance supportive parenting would ameliorate the association between ACEs and prediabetes status at age 25. Rural African American parents and their 11-year-old children (N=390) participated in the Strong African American Families (SAAF) program or a control condition. Each youth at age 25 provided a total ACEs score and a blood sample from which overnight fasting glucose was assayed. Logistic regression equations were used to test the hypotheses. The logistic regression analyses revealed a significant interaction between total ACEs and random assignment to SAAF or control, OR=0.56, 95% CI [0.36, 0.88]. Follow-up analyses indicated that, for participants in the control condition, a 1-point increase in ACEs was associated with a 37.3% increase in risk of having prediabetes. ACEs were not associated with the likelihood of having prediabetes among participants in the SAAF condition. Control participants with high total ACEs scores were 3.54 times more likely to have prediabetes than were SAAF participants with similar scores. This study indicated that participation at age 11 in a randomized controlled trial designed to enhance supportive parenting ameliorated the association of ACEs with prediabetes at age 25. If substantiated, these findings may provide a strategy for preventing negative health consequences of ACEs. Copyright © 2017 Elsevier Inc. All rights reserved.

    The flow inside the moderator tank of a CANDU-6 reactor during full power steady state operation has been suspected to be operating in the buoyancy/inertial driven mixed convection regime as illustrated in the middle figure. At some regions of the moderator tank where the buoyancy driven upward flow and the inertial momentum driven downward flows interface counter-currently, there exist some interface regions between these two flows like the middle one, and the local temperatures at these interface regions are known to oscillate with different amplitude at various fluctuation frequencies as shown. According to a numerical simulation of the moderator flow and temperature distribution at full power steady state carried out by previous researches showed that any small disturbances in the flow or temperature may initiate the system unstable and aggravate the asymmetric flow and temperature patterns. The tests at the 3-D Moderator Test Facility (MTF) that is a representative scaled-down of CANDU reactors, reproduced the expected and observed moderator behavior in the reactor as well as the local temperature fluctuations arising from the delicate balance of forced and buoyancy induced flow. This observation raised a safety concern as the local moderator temperature at some regions showed fluctuations with an amplitude that may jeopardize the safety margin, i.e. the difference between the available subcooling and the subcooling requirement. The scope of this paper is to review the basis of the safety concern related to this moderator subcooling and local temperature fluctuation and describe the current status of MCT erection and some of the experiments carried so far

    Background. There is limited research on the disclosure experiences of adolescents with perinatal acquired HIV (PAH). The study explores how adolescents with PAH experience living with HIV and examined their perceptions and experiences regarding disclosure and onward self-disclosure to friends and sexual partners. Methods. Thematic analysis was used to analyze in-depth interviews conducted with 37 adolescents. Findings. Adolescents received disclosure about their status at mean age of 12 years. They perceived disclosure as necessary and appreciated the truthful communication they received. Adolescents have learned to accept and live with HIV, and they desired to be healthy and normal like other people. After receiving disclosure, they found their treatment meaningful, and they adhered to medication. However, they also expressed a strong message that their HIV status was truly their secret and that self-disclosure to others will take the feeling of being normal away from them because they will be treated differently. Conclusion. Adolescents maintained secrecy in order to be accepted by their peers but also to protect themselves from stigma and isolation. Given that adolescents want to be informed of their HIV status but desire controlling self-disclosure of their HIV status, these should form the basis for development of disclosure interventions.

    An increasing proportion of pediatric cancer patients in the United States are Latino and many have Spanish-speaking immigrant parents with limited English proficiency (LEP). Little is known about how language or undocumented immigration status impacts their care experience. A cross-sectional survey was administered to English (N = 310) and Spanish-speaking LEP (N = 56) caregivers of pediatric cancer patients. To assess differences in healthcare experiences between the language groups, t-tests and chi-square statistics were used. Multivariable logistic regression evaluated associations between primary language and knowledge of clinical trial status. Spanish-speaking caregivers were more likely to report higher rates of quitting or changing jobs as a direct result of their child's cancer, and their children were more likely to experience a delay in education. Although Spanish-speaking caregivers reported higher satisfaction with care, 32% reported feeling that their child would have received better care if English was their primary language. Spanish-speaking caregivers were more likely to incorrectly identify whether their child was on a clinical trial compared with English-speaking caregivers. The majority of Spanish-speaking caregivers reported at least one undocumented caregiver in the household and 11% of them avoided or delayed medical care for their child due to concerns over their undocumented immigration status. Language barriers and undocumented immigration status may negatively impact the quality of informed decision-making and the care experience for Spanish-speaking LEP caregivers of pediatric cancer patients. These families may benefit from culturally appropriate Spanish language resources to improve communication and open a dialogue regarding undocumented immigration status. © 2016 Wiley Periodicals, Inc.

    threshold temperature and no further deformation is expected. Consequently, a sufficient condition to ensure fuel channel integrity following a large LOCA, is the avoidance of sustained calandria tubes dryout. If the moderator available subcooling at the onset of a large LOCA is greater than the subcooling requirements, a sustained calandria tube dryout is avoided. The temperature oscillations observed in reactor and in test measurements such as MTF need to be characterized and quantified to show that it does not jeopardize the currently available safety margins. Because of the importance of an accurate prediction of moderator temperature distributions and the related moderator subcooling, a 1/4 scaled-down moderator tank of a CANDU-6 reactor, called Moderator Circulation Test (MCT), was erected at KAERI and the current status of MCT experiment progress is described and further experiments are expected to be carried out to generate the experimental data necessary to validate the computer codes that will be used to analyze the accident analysis of operating CANDU-6 plants.

    Despite recommendations for disclosure of HIV status to children living with HIV (CLHIV), fewer than half of CLHIV at the Instituto Nacional de Salud del Niño (INSN) in Lima, Peru, have had disclosure. How and when the disclosure process for CLHIV should take place in Peru has not been studied. We conducted a qualitative study at INSN to explore perceptions and experiences of 6 health care providers (HCPs), 14 disclosed and nondisclosed CLHIV (8-17 years), and their 14 caregivers regarding knowledge of illness, disclosure of HIV status, and appropriate disclosure approaches. Disclosed children wanted to be told their diagnosis earlier. Nondisclosed children expressed frustration taking medications. Caregivers and HCPs discussed motivations to disclose, including educating, honesty, improving medication adherence, and preventing secondary transmission. Culturally appropriate guidelines and training for HCPs and caregivers are needed to support disclosure of children's HIV status and ongoing support for CLHIV.

Term agreement (Canada, Chinese Taipei, Czech Republic, Finland, France, Germany, Korea (Republic of), Japan, Slovak Republic, Spain, Sweden, Switzerland and United States of America). A key accomplishment of CODAP is the establishment of a framework for the systematic collection and evaluation of service-induced degradation and failure of passive metallic components. The Online Event Database facilitates data entry as well as database interrogation. The Online Knowledge Base allows for the capturing, sharing, transferring, storing and utilizing technical information on environmental degradation mechanisms, structural integrity evaluations, relevant R and D results, and national codes and standards for design and construction and in-service inspection. The Online Event Database includes almost 4700 event records from 324 commercial nuclear power plants. The Online Knowledge base includes country specific collections of documents and supporting information sorted by degradation mechanisms based on the events in the Online Event Database. This project report describes the status of the First Term (2011-2014) of the CODAP event database and knowledge base. A review of the operating experience as documented in the event database addresses trends-and-patterns, the effectiveness of various strategies to mitigate environmental degradation, and the experience with non-destructive examination.

    As the number of working cancer patients increases, workplace discrimination and its relationship to changes in employment status among cancer patients is becoming an increasingly important social concern. The aim of this study is to provide a comprehensive overview of the relationship between changes in employment status and discrimination following a diagnosis of cancer. A total of 748 cancer patients, aged 18 years and older, who were employed before receiving a diagnosis of cancer, were enrolled in this study. Patients were recruited from ten cancer centers in Korea. Sociodemographic data, work-related data, and clinical information, as well as information on changes in employment status and incidences of discrimination, were collected from all patients. A change in employment status was reported by 73.4% of the sample, with unemployment being the most common change (46.4%). Forty-two (5.6%) patients reported that they had experienced discrimination in the workplace. Reports of discrimination were only weakly correlated with changes in employment status, but were significantly correlated with forced unemployment. Additional analyses revealed that being female, being from a lower socioeconomic status group and having a disability were risk-factors for unemployment, while being male, being from a higher socioeconomic status group and having a disability were risk-factors for workplace discrimination or forced unemployment. More attention should be paid to vulnerable who are diagnosed with cancer. An individualized and culture-based approach should be taken to minimize undesirable changes in employment status and to reduce discrimination among patients receiving a diagnosis of cancer.

    Asylum seekers, refugees and persons without legal status have been reported to experience a range of difficulties when accessing public services and supports in the UK. While research has identified health care barriers to equitable access such as language difficulties, it has not considered the broader social contexts of marginalization experienced through the dynamics of 'othering'. The current study explores health and health care experiences of Somali and Iraqi asylum seekers, refugees and persons without legal status, highlighting 'minoritization' processes and the 'pathologization' of difference as analytical lenses to understand the multiple layers of oppression that contribute to health inequities. For the study, qualitative methods were used to document the lived experiences of asylum seekers, refugees and persons without legal status. Thirty-five in-depth interviews and five focus groups were used to explore personal accounts, reveal shared understandings and enable social, cognitive and emotional understandings of on-going health problems and challenges when seeking treatment and care. A participatory framework was undertaken which inspired collaborative workings with local organizations that worked directly with asylum seekers, refugees and persons without legal status. The analysis revealed four key themes: 1) pre-departure histories and post-arrival challenges; 2) legal status; 3) health knowledges and procedural barriers as well as 4) language and cultural competence. Confidentiality, trust, wait times and short doctor-patient consultations were emphasized as being insufficient for culturally specific communications and often translating into inadequate treatment and care. Barriers to accessing health care was associated with social disadvantage and restrictions of the broader welfare system suggesting that a re-evaluation of the asylum seeking process is required to improve the situation.

    Background To investigate the relationship of human semen parameters with season, age and smoking status. Methods The present study used data from subjects recruited into an ongoing cross-sectional study on the relationship between environmental agents and semen characteristics. Our population consisted of 306 patients who presented to the Vincent Memorial Andrology Laboratory of Massachusetts General Hospital for semen evaluation. Sperm concentration and motility were measured with computer aided sperm analysis (CASA). Sperm morphology was scored using Tygerberg Kruger strict criteria. Regression analyses were used to investigate the relationships between semen parameters and season, age and smoking status, adjusting for abstinence interval. Results Sperm concentration in the spring was significantly higher than in winter, fall and summer (p seasons. There were no statistically significant relationships between semen parameters and smoking status, though current smokers tended to have lower sperm concentration. We also did not find a statistically significant relationship between age and semen parameters. Conclusions We found seasonal variations in sperm concentration and suggestive evidence of seasonal variation in sperm motility and percent sperm with normal morphology. Although smoking status was not a significant predictor of semen parameters, this may have been due to the small number of current smokers in the study. PMID:15507127

    In intermediate depth disposal facility of radioactive waste in Japan, waste is surrounded with bentonite layer to retard interaction of the waste and groundwater, because the bentonite layer saturated with the groundwater has very low hydraulic conductivity. On the other hand, it is important to confirm stability of barrier system for stress generated together with swelling of the bentonite and to understand effect of increase of gas pressure because of generation of hydrogen gas by corrosion of metallic waste. To understand and evaluate the swelling behavior of the bentonite layer, JNES carries out the experiment. In the experiments, we carry out the swelling experiment to examine the swelling behavior of the bentonite layer and the gas migration experiment to understand the gas migration behavior in the bentonite layer, using engineering scale model of the disposal facility. The swelling experiment has been in operation since June 2010. After this experiment, the gas migration experiment will start in July 2011. (orig.)

    This paper explores the causal relationship between primary schooling and adult HIV status in Malawi and Uganda, two East African countries with some of the highest HIV infection rates in the world. Using data from the 2010 Malawi Demographic Health Survey and the 2011 Uganda AIDS Indicator Survey, the paper takes advantage of a natural experiment, the implementation of Universal Primary Education policies in the mid 1990s. An instrumented regression discontinuity approach is used to model the relationship between increased primary schooling and adult women's HIV status. Results indicate that a one-year increase in schooling decreases the probability of an adult woman testing positive for HIV by 0.06 (p primary schooling positively affects women's literacy and spousal schooling attainment in Malawi and age of marriage and current household wealth in Uganda. However primary schooling has no effect on recent (adult) sexual behavior. Copyright © 2014 The Author. Published by Elsevier Ltd.. All rights reserved.

    To assess the associations of self-identified lesbian, gay, bisexual, and questioning sexual orientation or transgender status (LGBTQ) and military experience with health indicators. We used data from the Fall 2012 National College Health Assessment. The survey included self-identified sociodemographic characteristics, mental (e.g., depression) and physical (e.g., human immunodeficiency virus) conditions, health risk behaviors (e.g., smoking), and social stressors (e.g., victimization). We used modified Poisson regression models, stratified by self-reported military service, to examine LGBTQ-related differences in health indicators, whereas adjusting for sociodemographic characteristics. Of 27,176 in the sample, among the military-experienced group, LGBTQ individuals had increased adjusted risks of reporting a past-year suicide attempt (adjusted risk ratio [aRR] = 4.37; 95% confidence interval [CI] = 1.39-13.67), human immunodeficiency virus (aRR = 9.90; 95% CI = 1.04-79.67), and discrimination (aRR = 4.67; 95% CI = 2.05-10.66) than their non-LGBTQ peers. Among LGBTQ individuals, military experience was associated with a nearly four-fold increased risk of reporting a past-year suicide attempt (aRR = 3.61; 95% CI = 1.46-8.91) adjusting for age, sex, race and ethnicity, marital status, depression, and other psychiatric diagnoses. Military experience may moderate health indicators among LGBTQ populations, and likewise, LGBTQ status likely modifies health conditions among military-experienced populations. Results suggest that agencies serving military populations should assess how and if the health needs of LGBTQ individuals are met. Published by Elsevier Inc.

    Guided by the life-course perspective, this study contributes to the family caregiving, aging, and disability literature by examining the daily experiences of three types of family caregivers in midlife and late adulthood. A sample of 162 caregivers from the National Survey of Midlife in the United States study completed interviews, questionnaires, and a Daily Diary Study. Multilevel models showed the patterns of daily time use did not differ by caregiver types. Caregivers of sons/daughters with developmental disabilities (DD) experienced more daily stressors than caregivers of parents with health conditions (HC) and caregivers of spouses with HC. Unmarried caregivers of sons/daughters with DD reported spending more time on daily leisure activities and exhibited greater daily stressor exposure than other family caregivers. Age did not moderate the associations between caregiver types and daily experiences. Findings highlight the important consideration of the caregivers' characteristics to better determine the quality of their daily experiences in midlife and late adulthood.

    We explored workplace experiences of 10 health care providers with HIV in the Netherlands. We used semi-structured interviews to discuss motivations for disclosure and concealment, reactions to disclosures, the impact of reactions, and coping with negative reactions. Reasons for disclosure were wanting to share the secret, expecting positive responses, observing positive reactions to others, wanting to prevent negative reactions, and being advised to disclose. Reasons for concealment included fearing negative reactions, observing negative reactions, previous negative experiences, having been advised to conceal, and considering disclosure unnecessary. Positive reactions included seeing HIV as a nonissue; showing interest, support, and empathy; and maintaining confidentiality. Negative reactions included management wanting to inform employees, work restrictions, hiring difficulties, gossip, and hurtful comments, resulting in participants being upset, taken aback, angry, depressed, or feeling resignation. Participants coped by providing information, standing above the experience, attributing reactions to ignorance, seeking social support, or leaving their jobs.

    Full Text Available A number of typological coincidences in the texts of the Polish-American writer Cz. Miłosz, a Nobel prize winner and German classic G. Von Rezzori are considered. The work of these authors is a result of the crisis of the twentieth century, tragic decline of the traditional culture that was associated with the status of a writer in exile. Biographical background appears very organic for their texts , and in this case it almost coincides: the parents of both future artists “temporarily” left their land when the the situation in the empires was not stable – the Austria-Hungarian (in the case of Rezzori and Russian ( in the case of Miłosz. Both writers lived in exile. In their opinion, topos of childhood tragically detached from the future life events, generated separate thematic and anthropological link in their creative work . In this sense “The Issa Valley” (“Dolina Issy” 1955 by Cz. Miłosz and “The Snows Of Yesteryear” (“Blumen im Schnee” 1989 by Rezzori are the most exemplary. The works of a number of other representatives of the European literature of the twentieth century (e.g., “Others shores” by V. Nabokov . The problem discussed is still relevant. Tendence to autobiographism as genre sign of their texts, and, in addition, the source of many images – primarily children and adolescent characters is evident. The most obvious typological parallels emerge in several dimensions: the perspective of ideological clichés (negation Nietzschean ideas of nihilism by each writer, specific system of images (including images of nannies Cassandra and Antonina, relection the typical paradigm , which presents a complete image of “the world of childhood”, besides – in relation to the issue of “language as poetic phenomenon” (Miłosz’s definition, that mirrors the multinational palette the lost homeland.

    The aim of this study was to determine the caries rate and periodontal status in a sample of pregnant women with HIV+ infections from Puerto Rico. A pilot study was conducted on a cross sectional convenience sample of 25 pregnant women with HIV+ infections from Puerto Rico who visit the CEMI clinic (Centro de Estudios Materno Infantil) at the University of Puerto Rico. The women subjects were evaluated for caries, DMFT (D: Decay tooth; M: Missing tooth due to caries; F: Filled tooth) index, oral lesions associated with HIV+/AIDS and periodontal disease parameters, with a Florida probe by a calibrated dentist on periodontal indexes such as as bleeding on probing, CEJ (cemento-enamel junction) and pocket depth. Periodontal disease was classified as having 4 sites with pocket depth greater than 4 mm and caries were identified following the Radike criteria. Data was statistically analyzed using the SSPS Program (Statistical Software Program for Social Sciences) and descriptive statistics were calculated. Mean DT (decayed teeth), MT (missing teeth due to caries), FT (filled teeth) and DMFT (decay, missing and filled teeth) were 4.8, 1.86, 5.3 and 12, respectively; mean sites of bleeding on probing=12.06; mean sites with pocket depth>4 mm=6.95 and mean sites with loss of attachment greater than 4 mm=7.66. [Almost 50% of the patients had generalized chronic periodontitis. A 72% prevalence of periodontal disease was found. No oral lesions related to HIV+/AIDS were reported. CD4 and viral load was statistically associated with bleeding on probing and severe signs of periodontal disease. High levels of dental disease were found in pregnant women with HIV+/AIDS infections from Puerto Rico, and these women were in need of substantial dental services.

    Full Text Available This paper presents a GIS-based research approach to investigating the status and dynamics of spawning areas of the Tsimlyansk Reservoir (within Volgograd Region, one of the largest inland fishery water bodies in the South of Russia.The spawning areas were considered in terms of the concept of ecotone origin, of the highly dynamic aquatic-terrestrial transitional environment in which temporary flooding is the main factor determining the diversity of spawning habitats, recruitment conditions, as well as ecosystem productivity.The processing and interpretation of Landsat images for the spring and low-water seasons for years between 2005 and 2016, in combination with other data (large-scale topographic maps, fishery research, and scientific papers allowed revealing the location of main spawning areas within the reservoir’s Upper section and to calculate their areas.For three case study sites located on the left bank of the reservoir, the main natural and anthropogenic factors determining the spawning conditions were identified. Retrospective analysis and synthesis of data on young fish composition and abundance between 1980 and today confirmed the importance of these sites for fish recruitment as well as the opportunities for their improvement by means of restoration measures.The output maps present the spatial distribution of the spawning areas and the environmental factors directly or indirectly affecting fish recruitment conditions. The most impacted areas have been determined, including the areas affected by abrasion, siltation and eutrophication processes, as well as pollution of the aquatic zone and water protection zone of the reservoir.The results of the research are useful both for understanding the general environmental conditions of the Tsimlyansk Reservoir and for supporting management decisions towards its improvement.

    Due to the anorexia-cachexia syndrome, cancer patients are already suffering from nutritional problems and weight loss by the time they receive their diagnosis and start chemotherapy. In the oncology outpatient clinic of a Swiss university hospital, patients currently undergo a nutritional assessment and receive individual counselling at the beginning of cancer treatment. This qualitative study explored cancer patients' experiences with weight loss and nutritional problems as well as how they experienced the assessment and the consecutive counselling by nurses. Interviews were conducted with 12 patients and qualitative content analysis was used for data analysis. Results showed that patients barely registered the weight loss and did not interpret it as an early warning signal. Nevertheless, they attempted to improve their nutritional habits soon after diagnosis, prior to receiving any counselling. The patients did not experience the assessment as troublesome. They appreciated the nurses' advice and implemented the suggestions they found appropriate. This study highlights the importance of patient education regarding weight loss and nutritional problems early in the course of an illness. Patients may not be aware of nutritional problems at this early stage and may lack the necessary specialised knowledge. Assessment and counselling provided by nurses offer targeted measures for prevention of malnutrition and weight loss.

    The present paper contains an investigation of the hydrodynamics of thin Aluminum foil accelerated by light-ion beams at KALIF using B{sub {Theta}}-diode. The peak power density in these experiments was 0.15 {+-} 0.05 TW/cm{sup 2}. In an earlier paper the authors have analysed the experimental data using an analytical equation of state. In the present paper the authors show that the state of these accelerated foils is sensitive to the equation of state data and use data based on more profound models. They combine EOS models designed for shock wave modelling describing melting, vaporization and experimental data on compression and unloading of porous matter with those developed for strongly ionised material based on the model of chemical equilibrium.

    The Surrogate nuclear reactions method, an indirect approach for determining cross sections for compound-nuclear reactions involving difficult-to-measure targets, is reviewed. Focusing on cross sections for neutron-induced reactions on actinides, we review the successes of past and present applications of the method and assess its uncertainties and limitations. The approximations used in the analyses of most experiments work reasonably well for (n,f) cross sections for neutron energies above 1-2 MeV, but lead to discrepancies for low-energy (n,f) reactions, as well as for (n,{gamma}) applications. Correcting for some of the effects neglected in the approximate analyses leads to improved (n,f) results. We outline steps that will further improve the accuracy and reliability of the Surrogate method and extend its applicability to reactions that cannot be approached with the present implementation of the method.

    In HIV-discordant relationships, the HIV-negative partner also carries the burden of a stigmatised disease. For this reason, couples often hide their HIV-discordant status from family, friends and community members. This perpetuates the silence around HIV-discordant relationships and impacts on targeted HIV prevention, treatment and counselling efforts. This article reports on experiences of stigma and discrimination among HIV-discordant couples in South Africa, Tanzania and Ukraine. During 2008, HIV-discordant couples who had been in a relationship for at least one year were recruited purposively through health-care providers and civil society organisations in the three countries. Participants completed a brief self-administered questionnaire, while semi-structured interviews were conducted with each partner separately and with both partners together. Interviews were analysed using thematic content analysis. Fifty-one couples were recruited: 26 from South Africa, 10 from Tanzania, and 15 from Ukraine. Although most participants had disclosed their HIV status to someone other than their partner, few were living openly with HIV discordance. Experiences of stigma were common and included being subjected to gossip, rumours and name-calling, and HIV-negative partners being labelled as HIV-positive. Perpetrators of discrimination included family members and health workers. Stigma and discrimination present unique and complex challenges to couples in HIV sero-discordant relationships in these three diverse countries. Addressing stigmatisation of HIV-discordant couples requires a holistic human rights approach and specific programme efforts to address discrimination in the health system.

    Full Text Available Abstract Background The specific age to which an HIV infected child can be disclosed to is stipulated to begin between ages 4 and 6 years. It has also been documented that before disclosure of HIV positive status to the infected child. Health care providers should consider children’s cognitive-developmental ability. However, observation and situation analysis show that, health care providers still feel uncomfortable disclosing the HIV positive status to the infected child. The aim of the study was to explore healthcare providers’ experiences in disclosure of HIV-positive status to the infected child. Methods A qualitative study involving 20 health care providers who attend HIV-positive children was conducted in September, 2014 in Dar es Salaam, Tanzania. Participants were selected from ten HIV care and treatment clinics (CTC by purposive sampling. An interview guide, translated into participants’ national language (Kiswahili was used during in-depth interviews. Sampling followed the principle of data saturation. The interviews focused on perspectives of health-care providers regarding their experience with paediatric HIV disclosure. Data from in-depth interviews were transcribed into text; data analysis followed qualitative content analysis. Results The results show how complex the process of disclosure to children living with HIV can be to healthcare providers. Confusion was noted among healthcare providers about their role and responsibility in the process of disclosing to the HIV infected child. This was reported to be largely due to unclear guidelines and lack of standardized training in paediatric HIV disclosure. Furthermore, healthcare providers were concerned about parental hesitancy to disclose early to the child due to lack of disclosure skills and fear of stigma. In order to improve the disclosure process in HIV infected children, healthcare providers recommended further standardized training on paediatric HIV disclosure with

In order to tackle this issue, the Corporacion de Lucha Contra el Sida (CLS has implemented a multidisciplinary, provider-initiated, population-based HIV testing/counselling strategy named BAFI. In this report, we describe the experience of CLS at reaching populations from low socioeconomic backgrounds in 2008-2009. Two different approaches were used: one led by CLS and local health care providers (BAFI-1 and the other by CLS and community leaders (BAFI-2. Both approaches included the following: consented HIV screening test, a demographic questionnaire, self-reported HIV knowledge and behaviour questionnaires, pre- and posttest counselling, confirmatory HIV tests, clinical follow-up, access to comprehensive care and antiretroviral treatment. A total of 2085 individuals were enrolled in BAFI-1 and 363 in BAFI-2. The effectiveness indicators for BAFI-1 and BAFI-2, respectively, were HIV positive-confirmed prevalence = 0.29% and 3.86%, return rate for confirmatory results = 62.5% and 93.7%, return rate for comprehensive care = 83.3% and 92.8%, and ART initiation rate = 20% and 76.9%. Although more people were reached with BAFI-1, the community-led BAFI-2 was more effective at reaching individuals with a higher prevalence of behavioural risk factors for HIV infection.

  18. Status and Prospects of Robotic Gastrectomy for Gastric Cancer: Our Experience and a Review of the Literature

    Directory of Open Access Journals (Sweden)

    Sejin Lee

    2017-01-01

    Full Text Available Since the first report of robotic gastrectomy, experienced laparoscopic surgeons have used surgical robots to treat gastric cancer and resolve problems associated with laparoscopic gastrectomy. However, compared with laparoscopic gastrectomy, the superiority of robotic procedures has not been clearly proven. There are several advantages to using robotic surgery for gastric cancer, such as reduced estimated blood loss during the operation, a shorter learning curve, and a larger number of examined lymph nodes than conventional laparoscopic gastrectomy. The increased operation time observed with a robotic system is decreasing because surgeons have accumulated experience using this procedure. While there is limited evidence, long-term oncologic outcomes appear to be similar between robotic and laparoscopic gastrectomy. Robotic procedures have a significantly greater financial cost than laparoscopic gastrectomy, which is a major drawback. Recent clinical studies tried to demonstrate that the benefits of robotic surgery outweighed the cost, but the overall results were disappointing. Ongoing studies are investigating the benefits of robotic gastrectomy in more complicated and challenging cases. Well-designed randomized control trials with large sample sizes are needed to investigate the benefits of robotic gastrectomy compared with laparoscopic surgery.

    1. Fluctuations in the quality of the habitat in which an animal lives can have major consequences for its behaviour and physiological state. In poor-quality habitat with low food availability, metabolically intensive foraging activity is likely to result in increased generation of reactive oxygen species, while scarcity of food can lead to a weakening of exogenously derived antioxidant defences. The consequent oxidant/antioxidant imbalance may lead to elevated oxidative stress. 2. Although the link between food availability and oxidative stress has been studied in the laboratory, very little is known about this relationship in the wild. Here, we investigate the association between territory quality (measured through food availability) and oxidative stress in the Seychelles warbler (Acrocephalus sechellensis). 3. Seychelles warblers are insectivorous birds that inhabit a fixed feeding territory year round. Individuals experience profound and rapid local fluctuations in territory quality within these territories, owing to changing patterns of vegetation defoliation resulting from seasonal changes in prevailing wind direction and wind-borne salt spray. 4. As expected, oxidant generation (measured as reactive oxygen metabolites; ROMs) was higher when territory quality was low, but there was no correlation between territory quality and antioxidant capacity (OXY). The negative correlation between territory quality and ROMs was significant between individuals and approached significance within individuals, indicating that the pattern resulted from individual responses to environmental variation. 5. ROMs and OXY levels within individuals were positively correlated, but the relationship between territory quality and ROMs persisted after including OXY as a covariate, implying that oxidative stress occurs in low territory quality conditions. 6. Our results indicate that the oxidative stress balance of an individual is sensitive to relatively short-term changes in territory

    Mistreatment of women in healthcare settings during childbirth has been gaining attention globally. Mistreatment during childbirth directly and indirectly affects health outcomes, patient satisfaction, and the likelihood of delivering in a facility currently or in the future. It is important that we study patients' reports of mistreatment and abuse to develop a deeper understanding of how it is perpetrated, its consequences, and to identify potential points of intervention. Patients' perception of the quality of care is dependent, not only on the content of care, but importantly, on women's expectations of care. This study uses rich, mixed-methods data to explore women's characteristics and experiences of mistreatment during childbirth among slum-resident women in Uttar Pradesh, India. To understand the ways in which women's social and cultural factors influence their expectations of care and consequently their perceptions of respectful care, we adopt a Cultural Health Capital (CHC) framework. The quantitative sample includes 392 women, and the qualitative sample includes 26 women. Quantitative results suggest high levels of mistreatment (over 57 % of women reported any form of mistreatment). Qualitative findings suggest that lack of cultural health capital disadvantages patients in their patient-provider relationships, and that women use resources to improve care they receive. Participants articulated how providers set expectations and norms regarding behaviors in facilities; patients with lower social standing may not always understand standard practices and are likely to suffer poor health outcomes as a result. Of importance, however, patients also blame themselves for their own lack of knowledge. Lack of cultural health capital disadvantages women during delivery care in India. Providers set expectations and norms around behaviors during delivery, while women are often misinformed and may have low expectations of care.

    To ascertain the impact of therapy on gonadal function and reproductive outcome among children treated for Hodgkin's disease, we reviewed the experience at Stanford University Medical Center during the years 1965-1986. There were 240 children 15 years of age or younger, 92 girls and 148 boys; with median follow-up of 9 years, maximum follow-up was 26 years. Of this cohort, data on gonadal function were available on 20 boys, 5 of whom were considered prepubescent; they had no clinical evidence of sexual maturation and were less than 13 years of age. Evaluation of the boys included testicular biopsy, semen analyses and the ability to procreate. Serum gonadotropin hormone levels (FSH, LH) were studied in 11 boys who also had semen analyses. Sexual maturation was attained in all boys without the need for androgen replacement. Among the eight boys treated with radiation alone, four were able to father a child (3 following 40-45 Gy pelvic radiation dose, 1 without pelvic radiation) from 3-19 years following treatment. Three others who received 30-44 Gy pelvic radiation were oligospermic when tested at 10 to 15 years post-treatment. Semen analyses in 10 of 12 (83%) boys who had been treated with six cycles of MOPP with or without pelvic radiation revealed absolute azoospermia with no evidence of recovery as along as 11 years of follow-up. Following prolonged azoospermia, 2 of the 12 boys (17%) had recovery of fertility, with normalization of sperm count and/or ability to procreate at 12 and 15 years following treatment. There was no correlation with serum gonadotropin levels and sterility. Data on menstrual history, pregnancy and offspring were available in 86 (92%) of the girls. Seventy-five of the 86 girls (87%) have normal menstrual function. However, none of the females who underwent pelvic radiation without prior oophoropexy has maintained ovarian function.

    One conspicuous problem seen in aged PWR plants is the PWSCC, which is considered to be caused by three factors, which are environment, material and stress. The degradation caused by PWSCC on high nickel content alloy (Alloy 600) at dissimilar material weld joints of steam generator nozzles has became conspicuous in Japan. This paper describes the mitigation technique used for the PWSCC, recent experiences on PWSCC issues and repair techniques implemented on Japanese steam generator nozzles with Alloy 600 weld. As a countermeasure against the PWSCC, ultrasonic shot peening (USP) was planned and conducted on the SG nozzles as a preventive maintenance in Japan. It has been confirmed that the stress near the inner surface can be converted into compressive stress by applying plastic strain to the surface using collision force of the shot material during the shot peening. USP employs the ultrasonic-wave vibration. The effects of this peening technique were confirmed by qualified test if there were undetectable cracks by ECT on the surface of the material. In Japan, there were 15 plants with SG nozzles which had Alloy 600 welds and these SG nozzles were inspected by ECT or VT as a confirmatory inspection before conducting the USP operation from 2006 to 2008. In these inspections, defects have been found at 19 hot nozzles in 8 plants. In addition, the defect in one of the plants has been found at the safe-end base metal made from stainless steel. In the root cause investigation result, it was confirmed that these cracks were typical PWSCC induced by high residual stress. These nozzles with defects were repaired by replacing the Alloy 600 welding material on surfaces exposed to primary water with the Alloy 690 welding material which has excellent PWSCC resistance. These material replacements were performed by cladding or replacement of nozzle safe end joint. These techniques are used not only to repair but also as a preventive maintenance. These mitigation or repair

    To describe and explore current practice, methods and experience of communicating carrier status information following newborn screening for cystic fibrosis (CF) and sickle cell (SC) disorders, to inform practice and further research. Three linked qualitative studies. All nine health regions in England. Child health screening coordinators in all English health regions, health professionals communicating results to parents and parents of newborn carriers. A preliminary phase of semi-structured telephone interviews with child health screening coordinators in all nine English health regions, and thematic analysis of data; semi-structured face-to-face interviews with purposeful samples of 67 family members of 51 infants identified by universal newborn screening as carriers of CF or SC with data analysis by constant comparison; and semi-structured telephone interviews, and focus groups, with a key informant sample of 16 differing health professionals currently tasked with communicating results to parents in a range of ways, with thematic analysis of data. Methods for and respondents' experiences of communication of carrier results varied considerably within and between regions, and within and between SC and CF contexts. Approaches ranged from letter or telephone call alone, to in-person communication in the clinic or at home, with health professionals from haemoglobinopathy, CF, screening and genetics backgrounds, or from community and primary care, such as health visitors with SC carrier results. Health professionals identified pros and cons of different methods, preferring opportunity for face-to-face communication with parents where possible, particularly for CF carrier results. They were concerned by regional variations in protocols, the lack of availability of translated information on SC carrier results, and the feasibility of sustaining more 'specialist' involvement at current levels, particularly for SC carriers. Parents were often poorly prepared for the

    Since 2015, Europe has been facing an unprecedented arrival of refugees and migrants: more than one million people entered via land and sea routes. During their travels, refugees and migrants often face harsh conditions, forced detention, and violence in transit countries. However, there is a lack of epidemiological quantitative evidence on their experiences and the mental health problems they face during their displacement. We aimed to document the types of violence experienced by migrants and refugees during their journey and while settled in Greece, and to measure the prevalence of anxiety disorders and access to legal information and procedures. We conducted a cross-sectional population-based quantitative survey combined with an explanatory qualitative study in eight sites (representing the range of settlements) in Greece during winter 2016/17. The survey consisted of a structured questionnaire on experience of violence and an interviewer-administered anxiety disorder screening tool (Refugee Health Screener). In total, 1293 refugees were included, of whom 728 were Syrians (41.3% females) of median age 18 years (interquartile range 7-30). Depending on the site, between 31% and 77.5% reported having experienced at least one violent event in Syria, 24.8-57.5% during the journey to Greece, and 5-8% in their Greek settlement. Over 75% (up to 92%) of respondents ≥15 years screened positive for anxiety disorder, which warranted referral for mental health evaluation, which was only accepted by 69-82% of participants. Access to legal information and assistance about asylum procedures were considered poor to non-existent for the majority, and the uncertainty of their status exacerbated their anxiety. This survey, conducted during a mass refugee crisis in a European Community country, provides important data on experiences in different refugee settings and reports the high levels of violence experienced by Syrian refugees during their journeys, the high prevalence of

    The observation of neutrino oscillations raises the possibility that there exist additional, undiscovered high-mass neutrinos, giving mass to Standard Model neutrinos via the seesaw mechanism. By pushing the collider energy frontier at the LHC, the possibility arises that these heavy neutrinos may be produced and identified. We summarise the latest LHC results of searches for heavy neutrinos in a variety of final states.

    Using data from a probability based sample of adult men who have sex with men (MSM) we examined the association of negative life factors during adolescence and adult HIV status. 521 MSM reported on experiences of connectedness to community, comfort with sexuality, harassment and discrimination due to their sexual orientation at ages 12-18 years. HIV status was determined by serological testing. Overall, men reported moderate levels of being harassed, being discriminated against and high levels of feeling disconnected from gay communities while reporting high levels of being uncomfortable with their sexuality at those ages. However, in analyses of scores on these factors, higher experiences of harassment, higher levels of discrimination and more discomfort with sexuality at these ages are associated with HIV-negative status as adults. This study suggests that the relationship between negative adolescent experiences among MSM and adult HIV infection may not be straightforward, but may also dependent upon aspects of the intensity of the negative experiences, the relationship of the victim and the perpertrator(s), the sexual identity of the victim at the time and/or the number of these experiences or the length of time over which they occurred. Studies investigating specific multiple stressors in adolescent gay development and their effect on adult health outcomes are needed.

  9. How do user experiences with different transport modes affect the risk of traffic accidents? From the viewpoint of licence possession status.

    Road accidents between different modes of transport-such as between automobiles and pedestrians, automobiles and bicycles, or automobiles and motorcycles-are frequent. In such cases, it is important to consider the other side's perspective. This involves the ability to correctly judge, for every given situation, how other people on the road perceive their surroundings and what they intend to do next. In this paper, we conduct two types of studies assuming that this kind of ability to consider perspectives is higher when the person is licenced to drive the mode of transport used by the other party. For Study 1, we analysed accidents involving senior citizens between the ages of 65 and 74 years, who collided with automobiles as pedestrians or cyclists (1656 and 3192 cases respectively), in terms of the accident category and type of road at the accident spot. The results indicate that possession or non-possession of a licence was irrelevant for accidents involving cyclists, but for accidents with pedestrians, senior citizens who did not possess a licence are likely to be involved in a greater number of accidents in places that require interaction with automobiles, such as while crossing at crosswalks or at intersections. For Study 2, we reviewed 875 ordinary first-class licence practical test examinees, categorised them according to their licence possession status (motorcycle licence, moped licence, or no licence), and made a category-wise comparison of the test instructor's assessment of their ability to make a left turn. The results showed that those who had a motorcycle or moped licence tended to make a left turn more safely. Thus, the results indicate that experience with different modes of transport is likely to reduce the risk of accidents. These findings may be used to popularise educational interventions encouraging users of various transport modes to consider the perspective of others (i.e. via perspective-taking).

    We aimed to show that the immune system is sensitive to the detrimental effects of inequality and social injustice, and splenic vulnerability to apoptosis may also increase. In order of better determination of immune responses to chronic social stress, we implemented food deprivation, food intake inequality, and unstable social status (a change of cage-mate every 3 days) for a period of 14 days in 60 male Balb/c mice. At the end of this stress period, nitric oxide (NO) production by peritoneal adherent cells and the serum concentration of corticosterone were measured. Moreover, the viability of peritoneal adherent cells and spleen lymphocytes was evaluated by MTT assay. The terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay was done to reveal the TUNEL-reactive apoptotic bodies in the spleen. Our results showed that food deprivation and inequality caused significant changes in the apoptosis of splenic cells in comparison with the control group (p social status did not cause a further increase in the viability of lymphocytes and peritoneal adherent cells, or NO production in animals that were food-deprived or experienced inequality. Serum concentration of corticosterone in all experimental groups, except for animals that experienced unstable social status only, significantly decreased versus the control group (p poverty and social inequality, but not unstable social status, affect immune responses and are likely involved in the induction of splenic apoptosis in mice. © 2017 S.

    1972-12-15

    I have reviewed the historical and contemporary experiments that guide us in choosing a post-Newtonian, relativistic gravitational theory. The foundation experiments essentially constrain gravitation theory to be a metric theory in which matter couples solely to one gravitational field, the metric field, although other cosmological gravitational fields may exist. The metric field for any metric theory can be specified (for the solar system, for our present purposes) by a series of potential terms with several parameters. A variety of experiments specify (or put limits on) the numerical values of the seven parameters in the post-Newtonian metric field, and other such experiments have been planned. The empirical results, to date, yield values of the parameters that are consistent with the predictions of Einstein's general relativity.

    Objectives of this study were to examine for associations of casino industry economic development on improving community health status and funding for public health services in two counties in the Mississippi Delta Region of the United States. An ecological approach was used to evaluate whether two counties with casino gaming had improved health status and public health funding in comparison with two noncasino counties in the same region with similar social, racial, and ethic backgrounds. Variables readily available from state health department records were used to develop a logic model for guiding analytical work. A linear regression model was built using a stepwise approach and hierarchical regression principles with many dependent variables and a set of fixed and nonfixed independent variables. County-level data for 23 variables over an 11-year period were used. Overall, this study found a lack of association between the presence of a casino and desirable health outcomes or funding for public health services. Changes in the environment were made to promote health by utilizing gaming revenues to build state-of-the-art community health and wellness centers and sports facilities. However, significant increases in funding for local public health services were not found in either of the counties with casinos. These findings are relevant for policy makers when debating economic development strategies. Analysis similar to this should be combined with other routine public health assessments after implementation of development strategies to increase knowledge of health outcome trends and shifts in socioeconomic position that may be expected to accrue from economic development projects.

    1999-01-01

    Purpose: To evaluate the significance of final microscopic resection margin status on treatment outcomes in women with early breast cancer who are treated with breast-conserving surgery and definitive breast irradiation. Methods and Materials: An analysis was performed of 1021 consecutive women with clinical Stage I or II invasive carcinoma of the breast treated with breast-conserving surgery and definitive breast irradiation. Complete gross excision of tumor was performed in all cases, and an axillary staging procedure was performed to determine pathologic axillary lymph node status. The 1021 patients were divided into four groups based on the final microscopic margin from the tumor excision or from the re-excision if performed. These four groups were: (a) 518 patients with negative margins; (b) 124 patients with focally positive margins; (c) 96 patients with focally close margins (≤ 2 mm); and (d) 283 patients with unknown margins. Results: Local failure was not significantly different in patients with negative, focally positive, focally close or unknown final pathologic margins of resection at 8 years (8% vs. 10% vs. 17% vs. 16%, respectively, p = 0.21). The 8-year outcome also was not different among the four groups for overall survival (86% vs. 83% vs. 88% vs. 81%, respectively, p = 0.13), cause-specific survival (89% vs. 86% vs. 88% vs. 83%, respectively, p 0.14), no evidence of disease survival (81% vs. 73% vs. 86% vs. 77%, respectively, p = 0.09), and freedom from distant metastases (85% vs. 75% vs. 86% vs. 79%, respectively, p = 0.08). Conclusion: These results demonstrate that selected patients with focally positive or focally close microscopic resection margins can be treated with breast-conserving surgery and definitive breast irradiation with 8-year local control rates and survival rates that are similar to those seen in breast-conservation patients with negative or unknown final resection margins

    We evaluated the diagnostic accuracy of Rh blood group, D antigen (RHD) fetal genotyping, using real-time polymerase chain reaction in maternal blood samples, in a racially mixed population. We performed a prospective study conducted between January 2006 and December 2007, analyzing fetal RHD genotype in the plasma of 102 D- pregnant women by real-time polymerase chain reaction, targeting exons 7 and 10 of the RHD gene. Genotype results were compared with cord blood phenotype obtained after delivery or before the first intrauterine transfusion when necessary. Most of the participants (75.5%) were under 28 weeks of pregnancy, and 87.5% had at least one relative of black ancestry. By combining amplification of two exons, the accuracy of genotyping was 98%, sensitivity was 100%, and specificity was 92%. The positive likelihood ratio was 12.5, and the negative likelihood ratio was 0. The two false-positive cases were confirmed to be pseudogene RHD by real-time polymerase chain reaction. There were no differences between the patients with positive or negative Coombs test ( P = 0.479). Determination of fetal RHD status in maternal peripheral blood was highly sensitive in this racially mixed population and was not influenced by the presence of antierythrocyte antibodies. © Thieme Medical Publishers.

    The present quantitative study evaluates the degree to which socioeconomic status (SES), as opposed to perceived need, determines utilisation of publicly funded home care in Ontario, Canada. The Registered Persons Data Base of the Ontario Health Insurance Plan was used to identify the age, sex and place of residence for all Ontarians who had coverage for the complete calendar year 1998. Utilisation was characterised in two dimensions: (1) propensity - the probability that an individual received service, which was estimated using a multinomial logit equation; and (2) intensity - the amount of service received, conditional on receipt. Short- and long-term service intensity were modelled separately using ordinary least squares regression. Age, sex and co-morbidity were the best predictors (P funded home care as well as how much care was received, with sicker individuals having increased utilisation. The propensity and intensity of service receipt increased with lower SES (P funded home care service was primarily based on perceived need rather than ability to pay, barriers to utilisation for those from areas with a high proportion of recent immigrants were identified. Future research is needed to assess whether the current mix and level of publicly funded resources are indeed sufficient to offset the added costs associated with the provision of high-quality home care.

The authors investigated to determine whether patients with breast cancer who had different socioeconomic status (SES) received different care and had different overall survival (OS) in Ontario, Canada. Women who were diagnosed with breast cancer between 2004 and 2009 were identified from the Ontario Cancer Registry and linked to provincial databases to ascertain patient demographics, screening, diagnosis, treatment patterns, and survival. SES was defined as neighborhood income by postal code and was divided into income quintiles (Q1-Q5; with Q5 the highest SES quintile). Univariable and multivariable analyses were used to examine the associations between: 1) SES and mammogram screening and breast cancer treatments, and 2) SES and OS. In total, 34,776 patients with breast cancer who had information on disease stage available at diagnosis were identified. Seventy-six percent of women were aged >50 years. Patients with higher SES were more likely to be diagnosed at an earlier stage (Q5 [44.3%] vs Q1 [37.7%]; odds ratio [OR], 1.31; 95% confidence interval [CI], 1.23-1.41; P cancer stage at diagnosis, adjuvant chemotherapy, trastuzumab, radiotherapy and surgery types, higher SES remained associated with better OS (P = .0017). In a universal health care system, higher SES is associated with greater screening and treatments and with better OS after adjusting for screening, cancer stage at diagnosis, and treatments. © 2015 American Cancer Society.

    Full Text Available Aim. Despite high levels of malnutrition, there is still very little information on the nutritional benefits of Spirulina, a natural alga that provides essential amino acids, rare essential lipids, and numerous minerals and vitamins, to undernourished children in the world. Methods. We carried out a prospective study of 50 children aged between six and 60 months. The intervention group consisted of 16 children who received 10 g of Spirulina daily, as well as the local diet administered by the nutritional centre, and the control group of 34 children who just received the local diet. Both groups of children were assessed on day zero, day 15, and day 30. Results. After treatment, the weight-for-age Z scores and weight-for-height Z scores increased significantly in the intervention group. At day 15, there was a statistically significant difference between the mean corpuscular volume, total proteins, and albumin (p<0.05 in both groups, in favour of the intervention group, and at day 30, this difference extended to all of the studied parameters (p<0.05. Conclusion. This study found that the nutritional status of undernourished children who received Spirulina supplements as well as the local diet administered by the nutritional centre improved quickly and significantly.

  11. Status Epilepticus

    Although the majority of seizures are brief and cause no long-term consequences, a subset is sufficiently prolonged that long-term consequences can result. These very prolonged seizures are termed “status epilepticus” (SE) and are considered a neurological emergency. The clinical presentation of SE can be diverse. SE can occur at any age but most commonly occurs in the very young and the very old. There are numerous studies on SE in animals in which the pathophysiology, medication responses, and pathology can be rigorously studied in a controlled fashion. Human data are consistent with the animal data. In particular, febrile status epilepticus (FSE), a form of SE common in young children, is associated with injury to the hippocampus and subsequent temporal lobe epilepsy (TLE) in both animals and humans.

    Full text: The octapeptide [DOTA]-1-Nal3-octreotide (DOTA-NOC) has 3 to 4 times higher binding affinity to sstr2 than DOTATOC (Wild 2003). We labeled this peptide with the Ga-68 (t1/2 68 min) and used it in pts with metastatic NET before/after PRRT for evaluating the sstr status by semiquantitative PET/CT imaging. Methods: Ga-68 was eluted from a Ge-68/Ga-68 generator using 0.1 M HCl. Following purifications, Ga-68 was eluted into a labeling vial containing 0.05 mg DOTA-NOC. Radiolabeling yields of >80% were achieved within 15 min at >95C. After purification (C18 cartridge) and a final elution, 370-700 MBq of Ga-68 DOTA-NOC were obtained with 100% radiochemical purity within 20 min (about 70% yield). Results: 1,500 PET/CT studies were performed in pts with histologically proven NET and progressive metastases before and after PRRT. Acquisition was started 20-270 min after injection of a mean of 100 MBq (46-260 MBq) Ga-68 DOTA-NOC using an LSO-based PET/CT (biograph DUO, Siemens). SUV were determined for all tumor lesions and normal tissues. SUV in metastases was as high as 152 whereas normal tissue was in the range of 0.4 (lung) to 33 (spleen). Outstanding PET/CT images of all known tumor lesions and in addition very small lymph node and bone metastases (<5 mm) were easily visualized as early as 20 min p.i. Clearly more lesions were detected as compared to Tc-99m EDDA-HYNIC-TOC or In-111 DOTA-NOC SPECT or as seen on CT or MRI images (especially regarding lymph node metastases, bone lesions and unknown primaries). Conclusions: Molecular receptor PET/CT imaging using the Ga-68-labeled somatostatin analogue DOTA-NOC detects neuroendocrine tumor metastases with very high diagnostic sensitivity and specificity. Semiquantitative uptake measurements (SUV) allow predicting the tumor uptake of Y-90 or Lu-177- labeled peptides before PRRT and are highly useful for therapy control to determine the 'molecular tumor response' which can precede the morphologic responses by months

    Lower cognitive performance is associated with poorer health and functioning throughout the lifespan and disproportionately affects children from lower socioeconomic status (SES) populations. Previous studies reporting positive associations between child home enrichment and cognitive performance generally had a limited distribution of SES. We evaluated the associations of SES and child enrichment with cognitive performance in a population with a wide range of SES, particularly whether enrichment attenuates associations with SES. Children were sampled from a case-control study of small-for-gestational-age (SGA) conducted in a public hospital serving a low SES population (final n=198) and a private hospital serving a middle-to-high SES population (final n=253). SES (maternal education and income) and perinatal factors (SGA, maternal smoking and drinking) were obtained from maternal birth interview. Five child home enrichment factors (e.g. books in home) and preschool attendance were obtained from follow-up interview at age 4.5 years. Cognitive performance was assessed with the Differential Ability Scales (DAS), a standardized psychometric test administered at follow-up. SES and enrichment scores were created by combining individual factors. Analyses were adjusted for perinatal factors. Children from the public birth hospital had a significantly lower mean DAS general cognitive ability (GCA) score than children born at the private birth hospital (adjusted mean difference -21.4, 95% CI: -24.0, -18.7); this was substantially attenuated by adjustment for individual SES, child enrichment factors, and preschool attendance (adjusted mean difference -5.1, 95% CI: -9.5, -0.7). Individual-level SES score was associated with DAS score, beyond the general SES effect associated with hospital of birth. Adjustment for preschool attendance and home enrichment score attenuated the association between individual SES score and adjusted mean DAS-GCA among children born at both of the

    Results of our search for short lived neutral particles emitted in K + decay are given. We also seek to make an accurate measurement of the branching ratio for π 0 → e + e - by looking for the decay chain K + → π + π 0 , π 0 → e + e - . The world average branching ratio for this decay is (1.8 +- 0.7) x 10 -7 based on about 30 events from two experiments. Theory predicts that this branching ratio should be of order 6 x 10 -8 . If the branching ratio remains at the 2 x 10 -7 level when measured with smaller errors, this could be an indication of new physics. 24 refs., 7 figs

    The reliable design of reactor core elements calls for precise knowledge of the 3D-temperature fields of the different components; this primarily applies to the fuel element cladding tubes, these being the first safety barrier. This paper describes and discusses where and how the 3D-temperature fields so far determined exclusively with the help of global thermohydraulic computer codes (SUBCHANNEL-Codes) have to be determined more accurately by local investigations. The basis of these investigations is the measurement of local velocities and temperatures in 19-rod bundle models of the SNR-300 fuel element performed at the Kernforschungszentrum Karlsruhe (KfK). Some important results of the extensive experimental investigations are reported and compared with global and local recalculations. Open problems are pointed out. The influence of the uncertainties in the thermohydraulic design with respect to the strength analysis are discussed. The most significant results and conclusions are: (1) The peripheral bundle region is the critical zone, which has to be investigated with priority. Here the maximal azimuthal temperature differences of the claddings are ten times higher than those in the central bundle region. (2) The present deviations between thermal experiments and global as well as local calculations are much too high. Within the parameters investigated a careful code adaptation to the experiments is of high priority. (3) The knowledge gaps concerning liquid metal heat transfer in irregular geometries have to be closed. (4) The hot-channel analysis has to be checked with respect to the latest more detailed knowledge of thermohydraulics. (author)

    Full Text Available Interacting land use demands and competing interests originating from fields such as agriculture, housing, mobility and nature conservation call for integrated governance approaches that incorporate disciplinary perspectives and arbitrate between them. The German research program “Sustainable Land Management” targets this challenge and provides an umbrella for a number of regional projects involving transdisciplinary system-oriented approaches to sustainable land use, connecting researchers and practitioners. This research note gives an insight into the experiences presented at the program’s fourth year status conference, held in October 2014 in Berlin. It focuses on cross-scalar and cross-sectoral approaches to governing urban-rural interdependencies of land use and scrutinizes debates on how to implement and disseminate project results.

    Full Text Available A major problem facing behavioral neuroscientists is a lack of unified, vendor-distributed data acquisition systems that allow stimulus presentation and behavioral monitoring while recording neural activity. Numerous systems perform one of these tasks well independently, but to our knowledge, a useful package with a straightforward user interface does not exist. Here we describe the development of a flexible, script-based user interface that enables customization for real-time stimulus presentation, behavioral monitoring and data acquisition. The experimental design can also incorporate neural microstimulation paradigms. We used this interface to deliver multimodal, auditory and visual (images or video stimuli to a nonhuman primate and acquire single-unit data. Our design is cost-effective and works well with commercially available hardware and software. Our design incorporates a script, providing high-level control of data acquisition via a sequencer running on a digital signal processor to enable behaviorally triggered control of the presentation of visual and auditory stimuli. Our experiments were conducted in combination with eye-tracking hardware. The script, however, is designed to be broadly useful to neuroscientists who may want to deliver stimuli of different modalities using any animal model.

  20. PWR Secondary Water Chemistry Control Status: A Summary of Industry Initiatives, Experience and Trends Relative to the EPRI PWR Secondary Water Chemistry Guidelines

    Fruzzetti, Keith; Choi, Samuel

    2012-09-01

    The latest revision of the EPRI Pressurized Water Reactor (PWR) Secondary Water Chemistry Guidelines was issued in February 2009. The Guidelines continue to focus on minimizing stress corrosion cracking (SCC) of steam generator tubes, as well as minimizing degradation of other major components / subsystems of the secondary system. The Guidelines provide a technically-based framework for a plant-specific and effective PWR secondary water chemistry program. With the issuance of Revision 7 of the Guidelines in 2009, many plants have implemented changes that allow greater flexibility on startup. For example, the previous Guidelines (Revision 6) contained a possible low power hold at 5% power and a possible mid power hold at approximately 30% power based on chemistry constraints. Revision 7 has established a range over which a plant-specific value can be chosen for the possible low power hold (between 5% and 15%) and mid power hold (between 30% and 50%). This has provided plants the ability to establish significant plant evolutions prior to reaching the possible power hold; such as establishing seal steam to the condenser, placing feed pumps in service, or initiating forward flow of heater drains. The application of this flexibility in the industry will be explored. This paper also highlights the major initiatives and industry trends with respect to PWR secondary chemistry; and outlines the recent work to effectively address them. These will be presented in light of recent operating experience, as derived from EPRI's PWR Chemistry Monitoring and Assessment (CMA) program (which contains more than 400 cycles of operating chemistry data).

    The present study was performed to assess, beyond socio-economic factors, independent associations between the health and nutritional status of children under 5 years old and (1) family behavioural factors related to women with regard to child care and (2) war-related experience by the household of hardships in Afghanistan. The subjects were all children born during the previous 5 years from 1400 households in Kabul Province, Afghanistan and were selected by multistage sampling in March 2006. Height and weight measurements of the children and culturally sensitive interviews with their mothers were conducted by household visits. Child mortality, morbidity and nutritional status were evaluated. Four areas were assessed as variables for family behavioural factors related to women: education of mothers, child marriage of the mothers, maternal autonomy in obtaining healthcare for children and preference for a female physician. Hardships experienced by the family were examined by determining their satisfaction of basic material needs and by any experience of being forced to leave a preferred residence. A total of 2474 children from 1327 households completed the examinations and interviews; among them, 101 children were deceased by the time of the interview visits. Diarrhoea (32.5%) and acute respiratory infection (41.0%) were common child health problems and both emaciation (12.4%) and linear growth retardation (39.9%) were prevalent. Regardless of the influence of economic, demographic, family behavioural or hardships experience factors, a lack of maternal autonomy (79.1%) was associated with the occurrence of acute respiratory infection (odds-ratio = 1.72; 95% confidence interval = 1.23, 2.40), and linear growth retardation of children (odds-ratio = 1.38; 95% confidence interval = 1.01, 1.90); a lack of education of the mother (71.7%) and child marriage of the mothers (18.3%) were associated with diarrhoea (odds-ratio = 1.84; 95% confidence interval = 1.40, 2.41; odds

    Bowles, Hannah Riley; Gelfand, Michele

    2010-01-01

    Bias in the evaluation of workplace misbehavior is hotly debated in courts and corporations, but it has received little empirical attention. Classic sociological literature suggests that deviance by lower-status actors will be evaluated more harshly than deviance by higher-status actors. However, more recent psychological literature suggests that discrimination in the evaluation of misbehavior may be moderated by the relative status of the evaluator because status influences both rule observance and attitudes toward social hierarchy. In Study 1, the psychological experience of higher status decreased rule observance and increased preferences for social hierarchy, as we theorized. In three subsequent experiments, we tested the hypothesis that higher-status evaluators would be more discriminating in their evaluations of workplace misbehavior, evaluating fellow higher-status deviants more leniently than lower-status deviants. Results supported the hypothesized interactive effect of evaluator status and target status on the evaluation of workplace deviance, when both achieved status characteristics (Studies 2a and 2b) and ascribed status characteristics (i.e., race and gender in Study 3) were manipulated.

    The SAFIR development represents a novel Positron Emission Tomography (PET) detector, conceived for preclinical fast acquisitions inside the bore of a Magnetic Resonance Imaging (MRI) scanner. The goal is hybrid and simultaneous PET/MRI dynamic studies at unprecedented temporal resolutions of a few seconds. The detector relies on matrices of scintillating LSO-based crystals coupled one-to-one with SiPM arrays and readout by fast ASICs with excellent timing resolution and high rate capabilities. The paper describes the detector concept and the initial results in terms of simulations and characterisation measurements.

    The present Argonne Tandem-Linac accelerator has operated in a reliable manner during the past year. The accelerator system provided 4402 hours of experimental beam time with a wide variety of heavy-ions. Figure 1 shows the beams which have been provided during the past year. New beams accelerated by the linac include 300 MeV 82 Se and 390 MeV 109 Ag. In tests, the tandem accelerated 102 MeV 127 I. This is the heaviest beam ever accelerated by the Argonne tandem. The long-term performance of the niobium resonators appears to be good. No significant degradation of performance has been observed for most resonators over many years of use with the exceptions of problems caused by catastrophic vacuum accidents. Resonators whose performance has deteriorated after vacuum accidents have recently been restored to their original performance state by a simple technique. The technique used is to rinse the interior of the resonator with a sequence of baths of solvents and water

    IAEA safeguards are at the present under critical review with regard to their purpose and effectiveness. This paper describes the development of the IAEA Safeguards System from the early days, when procedures were developed on an ad hoc basis, to the present day. The development of State Systems of Accounting for and Control of Nuclear Material (SSAC), and of sophisticated instrumentation, has been necessary to deal with the rapid growth in the quantities of nuclear material and in the number of facilities under safeguards. The paper also discusses some of the managerial and organizational issues that are inherent in such a large international inspectorate. (author)

    The SAFIR development represents a novel Positron Emission Tomography (PET) detector, conceived for preclinical fast acquisitions inside the bore of a Magnetic Resonance Imaging (MRI) scanner. The goal is hybrid and simultaneous PET/MRI dynamic studies at unprecedented temporal resolutions of a few seconds. The detector relies on matrices of scintillating LSO-based crystals coupled one-to-one with SiPM arrays and readout by fast ASICs with excellent timing resolution and high rate capabilities. The paper describes the detector concept and the initial results in terms of simulations and characterisation measurements.

  2. When status is grabbed and when status is granted: Getting ahead in dominance and prestige hierarchies.

    Science.gov (United States)

    de Waal-Andrews, Wendy; Gregg, Aiden P; Lammers, Joris

    2015-09-01

    What type of behaviour affords status, agentic, or communal? Research to date has yielded inconsistent answers. In particular, the conflict view holds that agentic behaviour permits the imperious to grab status through overt force, whereas the functional view holds that communal behaviour permits the talented to earn status through popular appeal. Here, we synthesize both views by taking into account the moderating role played by group hierarchy. Group hierarchy can range from being dominance based (where status is grabbed) to prestige based (where status is granted). In a field study (Study 1), and a laboratory experiment (Study 2), we demonstrate that in different groups, status can be achieved in different ways. Specifically, agentic behaviour promotes status regardless of hierarchy type, whereas the effect of communal behaviour on status is moderated by hierarchy type: it augments it in more prestige-based hierarchies but diminishes it in more dominance-based hierarchies. © 2014 The British Psychological Society.

    Full Text Available The review presents results of the creation of databases, geoinformation and information systems, catalogs and expert systems and atlases of the Northern European part of Russia. The main goals of the created products are to systematize existing information on water resources and water bodies and provide official information about water bodies of all subjects of water relations; predict current and future planning of water use, and also reasonably set fees for the use of water bodies and resources. An important application of the works performed in the NWPI is to solve problems related to ensuring environmental safety. The experience of development and technology for the implementation of GIS projects such as “Water Resources”, “Water Objects”, information and reference systems “Lakes, rivers, hydropower structures”, as well as the creation of electronic atlases of the White Sea and their catchment area and the geographical atlas of the region have been shown. The electronic and paper versions of the catalog of lakes and rivers of Karelia, GIS of hydro-technical constructions, GIS-underground waters, sources of technogenic impacts on water objects have been developed. A paper and GIS version of the Onego Lake atlas was created with blocks: сlimate, hydrology, hydrochemistry, hydrobiology, geology, water supply complex, etc. Work has been done to evaluate the overall assessment of hydrography of the territorial structure, quantitative and qualitative characteristics of water resources; inventories of lakes, rivers, groundwaters on maps with the scale smaller than 1: 100000 have been carried out, cadastral numbers have been assigned to water bodies; a quantitative assessment of the distribution of lakes and rivers in the basins of the White Sea and Baltic Sea and the main river watersheds, as well as classification of reservoirs according to size have been made. Expert systems have been developed to assess water quality, trophic

    We review the current status and the future perspectives of the Belle experiment and KEKB asymmetric e + e - collider. Thanks to many efforts of Belle collaborators and KEKB accelerator staffs, we could accumulate a 41.8 fb -1 data by the end of 2001 (more than 80 fb -1 data by the end of summer, 2002), also the KEKB recorded the highest peak luminosity (7.35 x 10 33 cm -2 s -1 ) in the world. Furthermore, the Super KEKB project is being proposed not only to extract the CP violation parameters and moduluses of the CKM matrix with high accuracy, but also to search for B rare decays and explore beyond the Standard Model

    Nanometals and nanotechnology have over the years been covered in papers, books and conferences - also in many Risoe International Symposia, where the 30th in 2009 dealt solely with nanostructured metals. Since then, rapid progress has been made in synthesis, characterization and modeling, and it is timely to discuss status and perspective also with a view on applications in an international forum such as the Risoe Symposium. Both keynote and contributed papers address important current problems illustrating global research and development in this field. Examples are the development of new synthesis techniques followed by characterization and modeling of microstructures both in 2D and 3D now starting to bridge the micrometer scales. The vital area of mechanical behavior is addressed by the development of new testing techniques and a broad effort to characterize and model mechanical properties of metals strengthened by dislocations and twins. This research has now led to new understanding of both strengthening mechanisms and strengh structure relationships based on experiments in combination with analytical and numerical modeling. The holistic approach to research on nanometals demonstrated by these proceedings can guide both scientists and technologists in their future work also with the aim of introducing into society this new group of advanced materials. Such an effort is important, as science and technology today is significantly affected by politics of governments and international institutions, and therefore a new initiative in the pressent is to include a discussion of research and development in the area of nanometals i USA, China and Japan.

    Within this paper we present an autonomic Computing resources management system, used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG, and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware, addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

    Until now, FISH has been the gold standard technique to identify HER2 amplification status in ambiguous cases of breast cancer. Alternative techniques have been developed to increase the capacities of investigating HER2 amplification status. The aims of this multicenter study in a large series of breast cancer patients were to prospectively compare the level of performance of CISH, SISH, and qPCR alternative techniques on paraffin-embedded core biopsies with "gold standard FISH" for evaluation of HER2 amplification status. This study was performed on 840 cases scored by immunohistochemistry (IHC): 0=317 (38%), 1+=183 (22%), 2+=109 (13%), 3+=231 (27%). Each of the 15 French centers participating in the study analyzed 56 breast carcinoma cases diagnosed on fixed paraffin-embedded core biopsies. HER2 amplification status was determined by commercially available FISH used as the reference technique with determination of the HER2/CEN17 ratio or HER2 copy number status. The alternative techniques performed on the same cases were commercially available SISH or CISH and a common qPCR method especially designed for the study including a set of 10 primer pairs: 2 for HER2 (exons 8 and 26), 5 to evaluate chromosome 17 polysomy TAOK1, UTP6, MRM1, MKS1, SSTR2 and 3 for diploidy control TSN, LAP3 and ADAMTS16. The concordance between IHC and FISH was 96% to 95% based on the HER2/CEN17 ratio (n=766) or HER2 copy number (n=840), respectively. The concordance of the alternative techniques with FISH was excellent: 97% and 98% for SISH (498 and 587 cases), 98% and 75% for CISH (108 and 204 cases) and 95% and 93% (699 and 773 cases) for qPCR based on the HER2/CEN17 ratio or HER2 copy number, respectively. Similarly, sensitivity ranged from 99% to 95% for SISH, 100% to 99% for CISH and 89% to 80% for qPCR. The concordance with FISH (ratio) in the 2+ cases was 89% for SISH, 100% for CISH and 93% for qPCR. These alternative techniques showed an excellent concordance with FISH in core

    Purpose of Review This review discusses management of status epilepticus in children including both anticonvulsant medications and overall management approaches. Recent Findings Rapid management of status epilepticus is associated with a greater likelihood of seizure termination and better outcomes, yet data indicate there are often management delays. This review discusses an overall management approach aiming to simultaneously identify and manage underlying precipitant etiologies, administer anticonvulsants in rapid succession until seizures have terminated, and identify and manage systemic complications. An example management pathway is provided. Summary Status epilepticus is a common neurologic emergency in children and requires rapid intervention. Having a predetermined status epilepticus management pathway can expedite management. PMID:25304961

From the weak interaction lagrangian an expression is obtained for the effective hamiltonian describing neutrino-lepton processes. The results of discussing the experimental status of the unified theories of weak and electromagnetic interactions are in agreement with the simplest version of the unified theories - the Weinberg-Salam theory. It has been noted that the accuracy of the experiments (not exceeding 20%) is insufficient and no information is available on diagonal terms of the hamiltonian

This can lead to social stigma and discrimination. Methodology A cross sectional institution based study was conducted among the patient of a leprosy clinic in a tertiary care center. WHOQOL-BREF questionnaire was used after taking consent from each study individual. Results Majority (69.8% of the patients was male and 41.3% of the study population belonged to below poverty line. Majority (85.7% of the study population were suffering from multi-bacillary type of leprosy. Though Majority (96.8% of the patients was receiving MDT (multi drug therapy regularly but still 33.33% of them were leading a poor quality of life. It has been seen that literacy, family type and time gap between starting of symptoms and initiation of treatment were significantly associated with quality of life. Discussion Different previous studies showed QOL (quality of life was associated with factors like SES (socio economic status, literacy and male gender, the present study revealed higher literacy, staying in the joint family and early treatment initiation helped to improve the QOL. Conclusion Better QOL was associated with higher educational status, good family support and early initiation of treatment among the leprosy patients.

    Status epilepticus (SE) describes persistent or recurring seizures without a return to baseline mental status, and is a common neurologic emergency. SE can occur in the context of epilepsy or may be symptomatic of a wide range of underlying etiologies. The clinician’s aim is to rapidly institute care that simultaneously stabilizes the patient medically, identifies and manages any precipitant conditions, and terminates seizures. Seizure management involves “emergent” treatment with benzodiazepines followed by “urgent” therapy with other anti-seizure medications. If seizures persist then refractory SE is diagnosed and management options include additional anti-seizure medications or infusions of midazolam or pentobarbital. This paper reviews the management of pediatric SE and RSE. PMID:25727508

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

  14. Management of status epilepticus.

    Pichler, M; Hocker, S

    2017-01-01

    Status epilepticus is a neurologic and medical emergency manifested by prolonged seizure activity or multiple seizures without return to baseline. It is associated with substantial medical cost, morbidity, and mortality. There is a spectrum of severity dependent on the type of seizure, underlying pathology, comorbidities, and appropriate and timely medical management. This chapter discusses the evolving definitions of status epilepticus and multiple patient and clinical factors which influence outcome. The pathophysiology of status epilepticus is reviewed to provide a better understanding of the mechanisms which contribute to status epilepticus, as well as the potential long-term effects. The clinical presentations of different types of status epilepticus in adults are discussed, with emphasis on the hospital course and management of the most dangerous type, generalized convulsive status epilepticus. Strategies for the evaluation and management of status epilepticus are provided based on available evidence from clinical trials and recommendations from the Neurocritical Care Society and the European Federation of Neurological Societies. © 2017 Elsevier B.V.

This research is an explorative and descriptive study on the socio-cultural aspects of food system. The data were collected through a direct interview and discussion with respondents as well as a direct observation at the location of respondents. A sample size of 338 households was drawn from the population. To obtain the data on the cultural aspects, history and  socio aspect of food, in-depth interviews was conducted with 19 key persons. The study was last for 12 months. In Outer Baduy, the factors significantly related to nutritional status are age, number of household size, income, nutritional knowledge, and wife’s ability to read. In Moslem Baduy, only age and income are related to the nutritional status of children. In Moslem Baduy and the Outer Baduy, the correlation between age and W/A or W/H is similar: namely, the higher the age, the lower would the Z-score for the W/A or W/H. The income is significantly correlated to the child nutritional status according to Z-score for W/A with a high correlation coefficient, that is, 0.61. This means that the higher the income, the higher would be the Z-score value for the W/A.  The distribution of adults according to BMI classification in Outer Baduy it shows that 12.7% husbands and 17.6% wives are thin (wasted, while the

  4. Risky business: When humor increases and decreases status.

    Science.gov (United States)

    Bitterly, T Bradford; Brooks, Alison Wood; Schweitzer, Maurice E

    2017-03-01

    Across 8 experiments, we demonstrate that humor can influence status, but attempting to use humor is risky. The successful use of humor can increase status in both new and existing relationships, but unsuccessful humor attempts (e.g., inappropriate jokes) can harm status. The relationship between the successful use of humor and status is mediated by perceptions of confidence and competence. The successful use of humor signals confidence and competence, which in turn increases the joke teller's status. Interestingly, telling both appropriate and inappropriate jokes, regardless of the outcome, signals confidence. Although signaling confidence typically increases status and power, telling inappropriate jokes signals low competence and the combined effect of high confidence and low competence harms status. Rather than conceptualizing humor as a frivolous or ancillary behavior, we argue that humor plays a fundamental role in shaping interpersonal perceptions and hierarchies within groups.

    The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide

    Maximova, Katerina; Krahn, Harvey

    2010-01-01

    This paper sought to examine which pre- and post-migration factors might be associated with changes in refugees' health status. Using linear regression, the associations between pre- and post-migration factors and changes in self-rated mental and physical health status were examined in 525 refugees from the 1998 Settlement Experiences of Refugees in Alberta study. Having spent time in a refugee camp and having held professional/managerial jobs in one's home country were associated with a greater decline in mental health status since arrival in Canada. Having completed a university degree in one's home country was associated with a greater decline in physical health status. Being employed was associated with greater improvements in mental health status. Perceived economic hardship was associated with greater declines in physical health status. A higher number of settlement services received during the first year in Canada was associated with greater improvements in both mental and physical health status. Longer residence in Canada was associated with greater declines in physical health status but not in mental health status. While little can be done to alter refugees' pre-migration experiences, public policies can affect many post-migration experiences in order to mitigate the negative health consequences associated with resettlement. Results of this study point to the need for continued provision of settlement services to assist refugees with job training, labour market access, and credential recognition, as well as counseling for refugees who experienced the trauma of living in a refugee camp.

    Full Text Available Background. Early detection of malformation is tremendously improved with improvement in imaging technology. Yet in a developing country like India majority of pregnant women are not privileged to get timely diagnosis. Aims and Objectives. To assess the present status and potential of first trimester ultrasonography in detection of fetal congenital structural malformations. Methodology. This was a retrospective observational study conducted at Sanjay Gandhi Postgraduate Institute of Medical Sciences. All pregnant women had anomaly scan and women with fetal structural malformations were included. Results. Out of 4080 pregnant women undergoing ultrasound, 312 (7.6% had fetal structural malformation. Out of 139 patients who were diagnosed after 20 weeks, 47 (33.8% had fetal structural anomalies which could have been diagnosed before 12 weeks and 92 (66.1% had fetal malformations which could have been diagnosed between 12 and 20 weeks. Conclusion. The first trimester ultrasonography could have identified 50% of major structural defects compared to 1.6% in the present scenario. This focuses on the immense need of the hour to gear up for early diagnosis and timely intervention in the field of prenatal detection of congenital malformation.

    In spite of the progress made in neoadjuvant therapy for operable non small-cell lung cancer (NSCLC), many issues remain unsolved, especially in locally advanced stage IIIA. Retrospective data of 163 patients diagnosed with stage IIIA NSCLC after surgery was analyzed. The patients were divided into two groups: a preoperative chemotherapy group including 59 patients who received platinum-etoposide doublet treatment before surgery, and an upfront surgery group including 104 patients for whom surgical resection was the first treatment step. Adjuvant chemotherapy or/and radiotherapy was administered to 139 patients (85.3%), while 24 patients (14.7%) were followed-up only. The rate of N2 disease was significantly higher in the upfront surgery group ( P   0.05). There was significant difference in preoperative chemotherapy group regarding relapse rate and treatment outcomes related to the lymph node status comparing to the upfront surgery group. Neoadjuvant/adjuvant chemo-therapy is a part of treatment for patients with stage IIIA NSCLC, but further investigation is required to determine optimal treatment. © 2017 The Authors.

  3. Rethinking status dystonicus.

    Ruiz-Lopez, Marta; Fasano, Alfonso

    2017-12-01

    Status dystonicus is a movement disorder emergency that has been a source of controversy in terms of terminology, phenomenology, and management since it was first described in 1982. Here we argue that the current use of the term status dystonicus falls well short of the precision needed for either clinical or academic use. We performed a critical review on this topic, describing possible pathophysiological mechanisms and areas of uncertainties. This review also addresses the problems derived by the extreme clinical heterogeneity of this condition, as the lack of an objective criterion useful for the definition, or the fact that status dystonicus may present not only in the context of a known dystonic syndrome. We propose a new possible definition that includes not only dystonia but also other hyperkinetic movements in the wide range of movement disorders that can be seen during an episode. The new definition keeps the term status dystonicus and highlights the fact that this is a medical emergency based on the impairment of bulbar and/or respiratory function requiring hospital admission as the principal feature. Furthermore, the new definition should not consider as necessary unspecific features as patient's condition at baseline, the distribution of dystonia, occurrence of systemic symptoms such as fever or laboratory findings. We hope that this proposal will stimulate the debate on this subject among our peers, further developing a clinical and pathophysiological understanding of status dystonicus. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    Full Text Available Refractory status epilepticus is a potentially life-threatening medical emergency. It requires early diagnosis and treatment. There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED, i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits.

Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits. PMID:24791086

    2017-01-01

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6,680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status—sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the effects of transitions on happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past five years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

  8. Status of voluntary restraint

    Energy Technology Data Exchange (ETDEWEB)

    Aarts, W. [SWOKA Institute for Strategic Consumer Behaviour, Leiden (Netherlands)

    2000-05-01

    Do people enjoying a higher status, especially those with a higher education, constrain their consumption more than others? In general, higher status and high levels of consumption go hand in hand. But the greater availability of luxury goods has led to a decline in their exclusivity. Since environmental awareness has increased, a countercurrent may be possible. It is possible that certain high status groups, the environmentally aware trendsetters, can now be distinguished by their voluntary restraint rather than by their conspicuous consumption. This hypothesis formed the basis for a sociological doctoral project at the University of Amsterdam. The research was conducted under the umbrella of the National Research Programme on Global Air Pollution and Climate Change.

  10. LHCb: Self managing experiment resources

    CERN Multimedia

    Stagni, F

    2013-01-01

    Within this paper we present an autonomic Computing resources management system used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System ( Resource Status System ) delivering real time informatio...

    After practical changes were approved to the initial conceptual design of the cryogenic system for MSU FRIB and an agreement was made with JLab in 2012 to lead the design effort of the cryogenic plant, many activities are in place leading toward a cool-down of the linacs prior to 2018. This is mostly due to using similar equipment used at CHLII for the 12 GeV upgrade at JLab and an aggressive schedule maintained by the MSU Conventional Facilities department. Reported here is an updated status of the cryogenic plant, including the equipment procurement status, plant layout, facility equipment and project schedule.

    The experiment NA64 is aimed at a search for a sub-GeV vector mediator (called dark photon A′) of Dark Matter production at the CERN SPS. . The main goal in 2017 was to probe a region of the A′ parameter space of the thermal dark matter model. Ongoing activities on the detector and data analysis are reviewed. The status and results from the NA64 runs in 2016 and 2017 are reported. First results on the search for the X->e+e− decay of a 17 MeV X boson, which could explain the recently observed excess of e+e-pairs from the excited 8Be nucleus transitions, and A'-> e+e- decays are also presented. Ongoing analysis on the decays of axion-like particles and plans for further searches beyond LS2 are also discussed.

  18. Variation in Subjective Aging by Sexual Minority Status.

    Science.gov (United States)

    Barrett, Anne; Barbee, Harry

    2017-06-01

    The past few decades have seen increased scholarly attention to gay and lesbian individuals' aging experiences; however, few studies examine differences in subjective aging by sexual minority status. We identify four perspectives on the association between sexual minority status and subjective aging-double jeopardy, crisis competence, gender interactive, and limited salience perspectives. We examine each perspective's predictions using data from the first wave of Midlife in the United States (1995-1996; MIDUS). Ordinary least square regression models reveal strongest support for the limited salience perspective, suggesting that sexual minority status has weaker effects on subjective aging than do other social factors, such as age, health, and gender. However, some results provide support for the gender interactive perspective, positing that the effect of sexual minority status on subjective aging varies by gender. Our study provides an organizational framework of theoretical perspectives that can guide further examinations of variation in aging experiences by sexual minority status.

  19. High & mighty: Implicit associations between space and social status

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Figurative language, the built environment, and our perceptuo-motor experiences frequently associate social status with physical space. Linguistic references such as high status or climbing the corporate ladder, and built places such as the U.S. Capitol building link social and physical hierarchies. In three experiments we examine the source and extent of these associations by testing whether people implicitly associate abstract social status indicators with concrete representations of spatial topography (level versus mountainous land and relatively abstract representations of cardinal direction (south and north. Experiment 1 demonstrates speeded performance during an Implicit Association Test (IAT; Greenwald et al., 1998 when average social status is paired with level topography and high status with mountainous topography. Experiments 2 and 3 demonstrate a similar effect but with relatively abstract representations of cardinal direction (south and north, with speeded performance when average and powerful social status are paired with south and north coordinate space, respectively. Abstract concepts of social status are perceived and understood in an inherently spatial world, resulting in powerful associations between abstract social concepts and concrete and abstract notions of physical axes. These associations may prove influential in guiding daily judgments and actions.

    The DIRAC Project was initiated to provide a data processing system for the LHCb Experiment at CERN. It provides all the necessary functionality and performance to satisfy the current and projected future requirements of the LHCb Computing Model. A considerable restructuring of the DIRAC software was undertaken in order to turn it into a general purpose framework for building distributed computing systems that can be used by various user communities in High Energy Physics and other scientific application domains. The CLIC and ILC-SID detector projects started to use DIRAC for their data production system. The Belle Collaboration at KEK, Japan, has adopted the Computing Model based on the DIRAC system for its second phase starting in 2015. The CTA Collaboration uses DIRAC for the data analysis tasks. A large number of other experiments are starting to use DIRAC or are evaluating this solution for their data processing tasks. DIRAC services are included as part of the production infrastructure of the GISELA Latin America grid. Similar services are provided for the users of the France-Grilles and IBERGrid National Grid Initiatives in France and Spain respectively. The new communities using DIRAC started to provide important contributions to its functionality. Among recent additions can be mentioned the support of the Amazon EC2 computing resources as well as other Cloud management systems; a versatile File Replica Catalog with File Metadata capabilities; support for running MPI jobs in the pilot based Workload Management System. Integration with existing application Web Portals, like WS-PGRADE, is demonstrated. In this paper we will describe the current status of the DIRAC Project, recent developments of its framework and functionality as well as the status of the rapidly evolving community of the DIRAC users.

    The report gives an account of the development of material and fabrication technology for copper canisters with cast inserts during the period from 2000 until the start of 2004. The engineering design of the canister and the choice of materials in the constituent components described in previous status reports have not been significantly changed. In the reference canister, the thickness of the copper shell is 50 mm. Fabrication of individual components with a thinner copper thickness is done for the purpose of gaining experience and evaluating fabrication and inspection methods for such canisters. As a part of the development of cast inserts, computer simulations of the casting processes and techniques used at the foundries have been performed for the purpose of optimizing the material properties. These properties have been evaluated by extensive tensile testing and metallographic inspection of test material taken from discs cut at different points along the length of the inserts. The testing results exhibit a relatively large spread. Low elongation values in certain tensile test specimens are due to the presence of poorly formed graphite, porosities, slag or other casting defects. It is concluded in the report that it will not be possible to avoid some presence of observed defects in castings of this size. In the deep repository, the inserts will be exposed to compressive loading and the observed defects are not critical for strength. An analysis of the strength of the inserts and formulation of relevant material requirements must be based on a statistical approach with probabilistic calculations. This work has been initiated and will be concluded during 2004. An initial verifying compression test of a canister in an isostatic press has indicated considerable overstrength in the structure. Seamless copper tubes are fabricated by means of three methods: extrusion, pierce and draw processing, and forging. It can be concluded that extrusion tests have revealed a

  14. Diagnostics for pellet experiments

    International Nuclear Information System (INIS)

    Johnson, R.R.

    1978-01-01

    The target diagnostics which are being used and planned in current laser driven ICF Experiments are described. Most of these diagnostics can be easily applied to future ion-beam fusion experiments. The status of laser fusion diagnostics has been much improved in the last 5 years and further improvements can be expected and should be available when the first ICF experiments using ion beams are performed. As an example, x-ray temporal and spatial resolutions are now approximately 5 psec and 3 μm, which is approximately a factor of 4 better than the resolution reported in the first implosion experiments. As one plans ahead for ion-beam fusion experiments it should be emphasized that high yield experiments are easier to diagnose provided adequate shielding is employed. However, in the event that the first high yield experiments fail it will be necessary to have diagnostics available to determine where the problems lie. In laser fusion it is interesting to note that higher laser powers are required now for breakeven experiments than first anticipated, mainly because some aspects of the laser-interaction physics were not recognized until the experiments were carefully diagnosed. Thus as has been pointed out, it may be necessary to increase the energy of the ion-beam driver to enable us to do breakeven experiments with high confidence

  15. Assessment of Mental Status.

    Finney, Glen R; Minagar, Alireza; Heilman, Kenneth M

    2016-02-01

    Assessing the mental status of patients with a neurobehavioral disorder is a critical element in the diagnosis and treatment of these patients. This assessment should always be performed after the patient's history it taken and a general physical as well as a neurologic examination is completed. The mental status examination commences with observing the patient's appearance and level of consciousness. The examiner should also pay attention to patient's social behavior, emotional state and mood. There are 3 major means of assessing a patient's mental status. One type attempts to determine if the patient is demented and the severity of the dementia as it pertains to their ability to perform activities of daily living as well as instrumental activities. A second type of assessment utilizes what may be termed as "screening tests" or "omnibus tests". These brief tests are performed independent of the patient's history and examination. The two most frequently used screening tests are the Mini-Mental Status Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). The third means of assessing a patient's mental status is by using specific neuropsychological tests that focus on specific domains of cognition, such as frontal executive functions, attention, episodic verbal and visuospatial memory, declarative knowledge such as language (speech, reading and writing) and arithmetical, as well as visuospatial and perceptual abilities. These neurobehavioral, neuropsychiatric and neuropsychological assessments of patients with a cognitive decline and behavioral abnormalities should often be accompanied by laboratory tests, and neuroimaging that can help determine the underlying pathologic process so that effective therapeutic and management approaches can be provided.

    The GERDA experiment is designed to search for neutrinoless double beta (0νββ) decay of {sup 76}Ge. In Phase I of the experiment a background index (BI) of 10{sup -2} cts/(keV.kg.yr) was reached. No signal has been found and a lower limit on the half-life of 2.1.10{sup 25} yr (at 90% C.L.) is extracted. The aim of Phase II is to double the Ge mass and further reduce the BI by an order of magnitude to explore half-lives of about 10{sup 26} yr. Thirty new Broad Energy Germanium (BEGe) detectors have been produced. These detectors are distinct for their improved energy resolution and enhanced pulse shape discrimination of signal from background events. Further background reduction will be reached by an active veto to read out argon scintillation light. The Phase II commissioning showed that two of the major background components, external γ-rays from {sup 214}Bi and {sup 208}Tl decays, can be suppressed up to two orders of magnitude. This talk presents the current status of the GERDA Phase II upgrade.

    CUORE is a cryogenic detector consisting of 988 TeO2 crystals, 750 g each, and will be operated at a temperature of ˜10 mK, to search for neutrinoless double beta decay (0νββ) of 130Te. The detector, in the final stages of construction at the Laboratori Nazionali del Gran Sasso (Italy), will start its operations in 2016. CUORE-0, its pilot experiment, has proven the feasibility of CUORE, demonstrating that the target background of 0.01 counts/keV/kg/y and the energy resolution of 5 keV are within reach. CUORE-0 also made the most precise measurement of the 2νββ decay. The expected sensitivity of CUORE to the 0νββ 130Te half-life is 9 ·1025y, for 5 years of data taking. Here, we report the most recent results of CUORE-0, their implications for CUORE, and the current status of the CUORE experiment.

  1. Status of memory loss.

    2012-01-01

    A 72-year-old woman presented with first onset of seizure with no prior history of cognitive dysfunction. EEG revealed focal non-convulsive status epilepticus. MRI brain showed a left temporal non-enhancing lesion. Temporal pole biopsy showed acute neuronal necrosis and astrocyte hyperplasia together with extensive amyloid plaques and neurofibrillary tangles. Perivascular oligodendroglial hyperplasia was present. Postmortem examination revealed extensive plaque and tangle disease. Perivascular oligodendroglial hyperplasia was limited to the left temporal area. The presence of focal perivascular oligodendroglial hyperplasia in the left temporal cortex, combined with extensive plaque and tangle disease may have contributed to the focal status epilepticus in this patient. Although the presence of focal perivascular oligodendroglial hyperplasia has been reported in cases of temporal lobe epilepsy, it has not been reported as a cause of seizure in patients with Alzheimer\\'s disease previously. Further studies for clinical-pathologic correlation would be required to confirm this hypothesis.

    NASA Lewis Research Center's Automated Status Notification System (ASNS) was born out of need. To prevent "hacker attacks," Lewis' telephone system needed to monitor communications activities 24 hr a day, 7 days a week. With decreasing staff resources, this continuous monitoring had to be automated. By utilizing existing communications hardware, a UNIX workstation, and NAWK (a pattern scanning and processing language), we implemented a continuous monitoring system.

    The social gradient in smoking rates persist with an overrepresentation of smoking and its associated harms concentrated within lower socioeconomic status (SES) populations. Low-SES smokers are motivated to quit but face multiple barriers when engaging a quit attempt. An understanding of the current treatment service model from the perspectives of treatment-seeking low-SES smokers is needed to inform the design of alternative smoking cessation support services tailored to the needs of low-SES populations. This qualitative study aimed to: i) explore low-SES smokers' recent quitting experiences; ii) assess factors that impact treatment engagement; and iii) determine the acceptability and feasibility of alternative approaches to smoking cessation. Low-SES participants (n = 24) previously enrolled in a smoking cessation RCT participated in either a semi-structured focus group or in-depth telephone interview. Data was obtained and analysed using thematic analysis from October 2015 to June 2016. Analysis was deductive from the interview guide and supplemented inductively. Participants expressed feelings of guilt and shame around their smoking behaviour and experienced stigmatisation for their smoking. Guilt, shame, and stigmatisation negatively impacted treatment seeking behaviours with most avoiding current quit services. Costs of pharmacotherapy and treatment adherence were commonly cited barriers to treatment success. Electronic-cigarettes were perceived to be unsafe due to uncertainty on their legal status and regulatory restrictions. Technology-based text-messaging quit support was endorsed as a more favourable alternative compared to existing behavioural treatment services. Stigmatisation was commonly endorsed and acted as an impediment to current treatment utilisation. Electronic-cigarettes may present a viable harm reduction alternative, but their likely uptake in socioeconomically disadvantaged groups in Australia is limited by smokers' uncertainty about their

    The criticality experiment program for large fast reactors by the joint research of the Power Reactor and Nuclear Fuel Development Corp. and the Department of Energy, USA, is called JUPITER Program. The experiment was carried out from April, 1978, to August, 1979, using the zero power plutonium reactor in ANL, and the analysis is carried out independently in Japan and USA. The experiment this time was carried out with two assemblies, ZPPR-9 and 10, and it is called JUPITER Phase 1. Two engineers were dispatched from PNC to ANL-Idaho for two years from August, 1978, and they took part in the planning, execution and analysis of the experiment to obtain the informations. The FBR Core Design Committee was installed in PNC, and has studied the core plan, experimental plan and the course of analysis. The JUPITER Phase 1 is the bench mark experiment to obtain the informations required at the initial stage of the nuclear design of demonstration reactor cores. The rating, object and progress of the JUPITER Phase 1, the outline of experiment, and the present state of the analysis of experiment are described. Hereafter, the general evaluation of the JUPITER Phase 1 will be carried out to clarify the problems when the present method of analysis is applied to large homogeneous reactors. Also the bench mark experiment on large heterogeneous reactors will be planned. (Kako, I.)

    The CLUE experiment uses a new cosmic ray detector array planned to operate for the next decade. It utilises a MWPC chambers sensitive to UV, to image Cherenkov radiation produced in cosmic ray showers. This approach is unique in that the instrument is insensitive to skylight backgrounds, has a threshold similar to that of visible Cherenkov experiments but a longer duty cycle. These features make possible a class of interesting cosmic ray physics experiments. The CLUE experiment has started operation with two of the ten telescopes that are foreseen for its beginning. These telescopes are at present at Roque de Los Muchachos in the Canary Islands, in the same site as the HEGRA experiment. A description of the telescopes is given and some data on the tests performed are presented. (orig.)

  1. The local-ladder effect: social status and subjective well-being.

    Anderson, Cameron; Kraus, Michael W; Galinsky, Adam D; Keltner, Dacher

    2012-07-01

    Dozens of studies in different nations have revealed that socioeconomic status only weakly predicts an individual's subjective well-being (SWB). These results imply that although the pursuit of social status is a fundamental human motivation, achieving high status has little impact on one's SWB. However, we propose that sociometric status-the respect and admiration one has in face-to-face groups (e.g., among friends or coworkers)-has a stronger effect on SWB than does socioeconomic status. Using correlational, experimental, and longitudinal methodologies, four studies found consistent evidence for a local-ladder effect: Sociometric status significantly predicted satisfaction with life and the experience of positive and negative emotions. Longitudinally, as sociometric status rose or fell, SWB rose or fell accordingly. Furthermore, these effects were driven by feelings of power and social acceptance. Overall, individuals' sociometric status matters more to their SWB than does their socioeconomic status.

    Since several years, IPSN has conducted an effort in order to evaluate the release of radioactive iodine in case of hypothetical severe accident in a realistic manner. This source-term evaluation is performed with IODE code which is a module of the EXCADRE system of codes. This code is validated against: -analytical experiments: in these experiments, IPSN studies radiolytic effects and chemical processes in the sump, organic formation, mass transfer, effect of spray (CARAIDAS experiment), - the CAIMAN semi global experiment; this experiment will allow to study the phenomena linked to iodine behavior under representative containment geometry in the presence of painted surfaces and global irradiation, - the PHEBUS FP program. The paper consists to describe succinctly the current status of IODE and the various experiments for its validation. In case of hypothetical severe accident iodine can induce important perturbations of human organism. The effects are principally radiological, in particular on the thyroid. At short term, radioactive iodine is the most important contributor for the sanitary risk. It represents 55% of effective dose and 92% of thyroid dose at 10 km in case of controlled rejects with current assumptions. This is the reason why it must be actively studied. In France, the safety evaluations are performed with mechanistic codes or lumped parameter codes like EXCADRE which contains a module devoted to iodine studies: IODINE. The objective of the French experimental program on iodine is to understand and quantify important phenomena in order to put kinetic parameters in IODE module. The experiments can be classified in analytical experiments, the semi-global experiment CAIMAN which takes into account different phenomena studied in analytical experiments and the global experiment PHEBUS PF, not only devoted to iodine behavior study. In the following text we will present the needs of IODINE code and these different experiments. (author).

    The International Atomic Energy Agency is performing safeguards at some nuclear power reactors, 50 bulk processing facilities, and 170 research facilities. Its verification activities require the use of instruments to measure nuclear materials and of surveillance instruments to maintain continuity of knowledge of the locations of nuclear materials. Instruments that are in use and under development to measure weight, volume, concentration, and isotopic composition of nuclear materials, and the major surveillance instruments, are described in connection with their uses at representative nuclear facilities. The current status of safeguards instrumentation and the needs for future development are discussed

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M and O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    Tele-radiology is a term becoming increasingly popular in the medical literature. Nevertheless, terminological definitions in this particular field are still rather vague. The scope of applications extend from simple image presenting via analogue telephone lines to transmission of 3-D medical images through a satellite. It is a matter of standards highly differing in terms of data transmission rates, safety, technical demands on the systems and the like. In this article new information technologies, technical aspects, as well as some major applications of tele-radiology are discussed. The current status of tele-medicine/tele-radiology in this country is likewise briefly outlined

    Scleromyxedema is a rare dermatologic disorder, characterized by erythematous or yelowish lichenoid waxy papules. Neurological manifestations are rare but wel-recognized. A 51-year-old woman, diagnosed with scleromyxedema, was admitted to the hospital with status epilepticus, caused by brain lesions, as disclosed in a brain magnetic resonance imaging (MRI). The patient was treated with anticonvulsants and corticosteroids and gradualy recovered fuly. A complete remission of the lesions was shown in a folow-up brain MRI. In cases with scleromyxedema and the presence of neurological manifestations, we need to pay attention to central nervous system involvement, especialy when combined with brain MRI lesions, and treat the patient appropriately.

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    2001-01-01

    The applications of nuclear technology started in Morocco in the early sixties and were developed particularly in the sectors of Agriculture, Education and Medicine. In the early seventies, these applications were extended to other important sectors such as Industry using gauges and NDT techniques, Mines and Hydrology. But a lack of sufficient and adequate infrastructure has limited the development of these applications. Further more, as Morocco relies totally on foreign imports to meet its energy needs, the option of nuclear power generation started to be considered seriously. This was the initiator of a real national reflection on an integrated program for all peaceful applications of nuclear energy which led to the progressive constitution of an institutional and regulatory frame. In this context, the National Center for Nuclear energy, Sciences and Techniques (CNESTEN), which is a public institution, was created in 1986. Its current programme and future are described in the paper. (author)

    Lopez, J.L.; Nanopoulos, D.V.; Zichichi, A.

    1994-01-01

    Among the most outstanding conceptual developments in particle physics we have: the unification of all particle interactions at very-high energies (Grand Unification), the fermion-boson symmetry (Supersymmetry), the non-point-like structure of elementary particles (String theory), and the understanding that all dynamical quantities (gauge couplings, masses, Yukawa coupling) run with energy (Renormalization Group Equations). The goal is to make use of these great developments to construct a theory which embraces all fundamental forces of Nature, including gravity. In this review we address this problem and its possible implications for physics in the energy range where our experimental facilities operate. We show that what is required are not qualitative arguments but a set of detailed calculations with definite predictions. (Author)

    The LACE program, sponsored by an international consortium, is investigating inherent aerosol behavior for three postulated high consequence accident sequences; the containment bypass or V-sequence, failure to isolate containment, and delayed containment failure. Six large-scale tests are described which focus on these accident situations and which will be completed in the Containment Systems Test Facility at the Hanford Engineering Development Laboratory. The aerosol generation systems used to generate soluble and insoluble aerosols for the large-scale tests are described. The report then focuses on those tests which deal with the containment bypass accident sequence. Test results are presented and discussed for three containment bypass scoping tests

    Up to December 2000, more than 1700 MOX fuel assemblies have been delivered by Framatome ANP/Fragema to 20 French, 2 Belgian and 3 German PWRs. More than 1000 MOX fuel assemblies have been delivered by Framatome ANP GmbH (formerly Siemens) to 11 German PWRs and BWRs and to 3 Swiss PWRs. Operating MOX fuel up to discharge burnups of about 45,000 MWd/tM is done without any penalty on core operating conditions and fuel reliability. Performance data for fuel and materials have been obtained from an outstanding surveillance program. The examinations have concluded that there have been no significant differences in MOX fuel assembly characteristics relative to UO 2 fuel. The data from these examinations, combined with a comprehensive out-of-core and in-core analytical test program on the current fuel products, are being used to confirm and upgrade the design models necessary for the continuing improvement of the MOX product. As MOX fuel has reached a sufficient maturity level, the short term step is the achievement of the parity between UO 2 and MOX fuels in the EdF French reactors. This involves a single operating scheme for both fuels with an annual quarter core reload type and an assembly discharge burnup goal of 52,000 MWd/tM. That ''MOX parity'' product will use the AFA-3G assembly structure which will increase the fuel rod design margins with regards to the end-of-life internal pressure criteria. But the fuel development objective is not limited to the parity between the current MOX and UO 2 products: that parity must remain guaranteed and the MOX fuel managements must evolve in the same way as the UO 2 ones. The goal of the MOX product development program underway in France is the demonstration over the next ten years of a fuel capable of reaching assembly burnups of 70,000 MWd/tM. (author)

    For the very low emittance beams in CLIC, it is vital to mitigate emittance growth which leads to reduced luminosity in the detectors. One factor that leads to emittance growth is transverse wakefields in the accelerating structures. In order to combat this the structures must be aligned with a precision of a few um. For achieving this tolerance, accelerating structures are equipped with wakefield monitors that measure higher-order dipole modes excited by the beam when offset from the structure axis. We report on such measurements, performed using prototype CLIC accelerating structures which are part of the module installed in the CLIC Test Facility 3 (CTF3) at CERN. Measurements with and without the drive beam that feeds rf power to the structures are compared. Improvements to the experimental setup are discussed, and finally remaining measurements that should be performed before the completion of the program are summarized.

    HSX is a quasi-helically symmetric (QHS) stellarator currently under construction at the Torsatron-Stellarator Laboratory of the University of Wisconsin-Madison. This device is unique in its magnetic design in that the magnetic field spectrum possesses only a single dominant (helical) component. This design avoids the large direct orbit losses and the low-collisionality neoclassical losses associated with conventional stellarators. The restoration of symmetry to the confining magnetic field makes the neoclassical confinement in this device analogous to an axisymmetric q=1/3 tokamak. The HSX device has been designed with a clear set of primary physics goals: demonstrate the feasibility of construction of a QHS device, examine single particle confinement of injected ions with regard to magnetic field symmetry breaking, compare density and temperature profiles in this helically symmetric system to those for axisymmetric tokamaks and conventional stellarators, examine electric fields and plasma rotation with edge biasing in relation to L-H transitions in symmetric versus non-symmetric stellarator systems, investigate QHS effects on 1/v regime electron confinement, and examine how greatly-reduced neoclassical electron thermal conductivity compares to the experimental χ e profile. 3 refs., 4 figs., 1 tab

    FIRE is a compact, high field tokamak being studied as an option for the next step in the US magnetic fusion energy program. FIRE's programmatic mission is to attain, explore, understand, and optimize alpha-dominated plasmas to provide the knowledge necessary for the design of attractive magnetic fusion energy systems. This study began in 1999 with broad participation of the US fusion community, including several industrial participants. The design under development has a major radius of 2 m, a minor radius of 0.525 m, a field on axis of 10T and capability to operate at 12T with upgrades to power supplies. Toroidal and poloidal field magnets are inertially cooled with liquid nitrogen. An important goal for FIRE is a total project cost in the $1B range. This paper presents an overview of the engineering details which were developed during the FIRE preconceptual design study in FY99 and 00

    1984-01-01

    The decision to devote the 1984 conference to nuclear power is timely and appropriate. Illinois has a long, and distinguished history in the development of civilian nuclear power. The concept was born at the University of Chicago, developed at Argonne National Laboratory and demonstrated on the Commonwealth Edison system at our pioneer Dresden Nuclear Station. Today, Illinois ranks number one in the nation in nuclear generation. With over a quarter century of commercial operating experience, nuclear power has proven its worth and become a significant and growing component of electric power supply domestically and throughout the world. Despite its initial acceptance, however, the nuclear power industry in the U.S. is now in the midst of a difficult period of readjustment stemming largely from the economic and regulatory problems of the past decade. As a result, the costs of plants under construction have increased dramatically, causing serious financial difficulties for several projects and their owners. At the same time, the U.S. is facing hard choices concerning its future energy supplies. Conferences such as this have an important role in clarifying the issues and helping to find solutions to today's pressing energy problems. This paper summarizes the status of nuclear power both here and abroad, discussing the implications of current events in the context of national energy policy and economic development here in Illinois

    Full Text Available The older population is increasing worldwide and in many countries older people will outnumber younger people in the near future. This projected growth in the older population has the potential to place significant burdens on healthcare and support services. Meeting the diet and nutrition needs of older people is therefore crucial for the maintenance of health, functional independence and quality of life. While many older adults remain healthy and eat well those in poorer health may experience difficulties in meeting their nutritional needs. Malnutrition, encompassing both under and over nutrition increases health risks in the older population. More recently the increase in obesity, and in turn the incidence of chronic disease in older adults, now justifies weight management interventions in obese older adults. This growing population group is becoming increasingly diverse in their nutritional requirements. Micro-nutrient status may fluctuate and shortfalls in vitamin D, iron and a number of other nutrients are relatively common and can impact on well-being and quality of life. Aging presents a number of challenges for the maintenance of good nutritional health in older adults.

Assessment of the future for this reactor system is reviewed with consideration of both advantages and disadvantages. Application of this concept to ADTT (accelerator driven transmutation technology) needs appears to be feasible by drawing on the MSRE experience. Key chemical considerations remain as: solubility, redox behavior, and chemical activity and their importance to ADTT planning is briefly explained. Priorities in the future development of molten salts for these applications are listed, with the foremost being the acceptance of the 2LiF-BeF 2 solvent system. 8 refs, 2 figs

    A validated cyanide assay that is applicable to a variety of tank waste matrices is necessary to resolve certain waste tank safety issues and for purposes of overall waste characterization. The target for this effort is an assay with an applicable range of greater than 1,000 ppM (0.10 wt%) total cyanide and a confidence level greater than 80%. Figure 1 illustrates the operating regime of the proposed cyanide assay method. The Assay Development Status Report for Total Cyanide will summarize the past experience with cyanide analyses on-tank waste matrices and will rate the status of the analytical methods used to assay total cyanide (CN - ion) in the tank waste matrices as acceptable or unacceptable. This paper will also briefly describe the current efforts for improving analytical resolution of the assays and the attempts at speciation

    Health care services for registered "band" Indians in Ontario are provided primarily by the Canadian Federal Government. Complex management methods preclude the direct involvement of Indian people in the decisions for their health resource allocation. Health indicators, need, and health status indexes are reviewed. The biostatistics of mortality and demography of the Indian and reference populations are aggregated with hospitalization/morbidity experience as the Chen G'1 Index, as an indicator of normative and comparative need. This is weighted by linear measurements of perceived need for preventive medicine programs, as ranked and scaled values of priorities, Zj. These were determined by community survey on 11 Indian reserves using a non-probabilistic psychometric method of "pair comparisons," based upon "Thurstone's Law of Comparative Judgement.," The calculation of the aggregate single unit Indian Health Status Index [Log.G'1].Zj and its potential application in a "zero-base" budget is described.

    Status epilepticus has a wide etiological spectrum, and significant morbidity and mortality. Management using a pre-determined uniform protocol leads to better outcomes. Multiple protocols for management of childhood status epilepticus are available, without much consensus. A 'Multi-disciplinary Consensus Development Workshop on Management of Status Epilepticus in Children in India' was organized. The invited experts included Pediatricians, Pediatric neurologists, Neurologists, Epileptologists, and Pediatric intensive care specialists from India, with experience in the relevant field. Experts had previously been divided into focus groups and had interacted on telephone and e-mail regarding their group recommendations, and developed consensus on the topic. During the meeting, each group presented their recommendations, which were deliberated upon by the house and a consensus was reached on various issues; the document was finalized after incorporating suggestions of experts on the draft document. To provide consensus guidelines on evaluation and management of convulsive status epilepticus in children in India (excluding neonatal and super-refractory status epilepticus). Each institution should use a pre-determined protocol for management of status epilepticus; pre-hospital management and early stabilization is the key to a satisfactory outcome of status epilepticus. Pharmacotherapy should not be delayed for any investigations; the initial management should consist of a parenteral benzodiazepine by any route feasible. Subsequent management has been detailed. The group also felt the need for more epidemiological research on status epilepticus from India, and identified certain research areas for the purpose.

    Full Text Available Status epilepticus and refractory status epilepticus represent some of the most complex conditions encountered in the neurological intensive care unit. Challenges in management are common as treatment options become limited and prolonged hospital courses are accompanied by complications and worsening patient outcomes. Antiepileptic drug treatments have become increasingly complex. Rational polytherapy should consider the pharmacodynamics and kinetics of medications. When seizures cannot be controlled with medical therapy, alternative treatments, including early surgical evaluation can be considered; however, evidence is limited. This review provides a brief overview of status epilepticus, and a recent update on the management of refractory status epilepticus based on evidence from the literature, evidence-based guidelines, and experiences at our institution.
