  1. El civismo en Pereira

    John Jaime Correa Ramírez

    2007-01-01

    Full Text Available Este proyecto quiere ir más allá de hacer un recuento cronológico de las grandes gestas cívicas de la ciudad. Interesa de modo particular dar cuenta del tipo específico de sociabilidades políticas que permitió la aparición de instituciones cívicas y educativas, con el fin de promover el desarrollo de la ciudad como una tarea colectiva. También estudia la injerencia de estas sociabilidades en la esfera pública local, a través de los medios de comunicación, de su participación en el Concejo Municipal o en la creación de un importante número de instituciones educativas de profunda recordación en la historia de la ciudad. Este tipo de sociabilidad constituye una forma particular de entender la participación y las virtudes democráticas de la sociedad, al investir a sus miembros del derecho abstracto de la participación dentro de la propia estructura de cada organización y en la definición, en conjunto, de los proyectos de civismo y de ciudadanía. Por esta vía se espera un acercamiento a la historia de la ciudad de Pereira, a partir del análisis de las tensiones o afinidades entre lo público y lo privado. De igual manera, realiza un ejercicio de análisis del discurso cívico que se promovió en Pereira, como elemento central de la ideología progresista que rigió los destinos de la ciudad, durante buena parte de su historia. Para entender las relaciones de poder y de control social de unos grupos sobre otros, es necesario analizar la forma como el discurso expresa creencias, valores, prácticas, consensos u opiniones ideológicas. No se trata de quedarse en el simple análisis de las estructuras lingüísticas o en estrategias comunicativas que se dan en la transferencia de información entre emisores y receptores. La investigación, a realizarse desde fuentes oficiales, institucionales, prensa local y entrevistas, exige comprender que el discurso está relacionado con un universo de interacciones culturales, que le dan

  2. Helios movable Hartmann ball

    Tucker, H.E.; Day, R.D.; Hedges, R.O.; Hanlon, J.A.; Kortegaard, B.L.

    1981-01-01

    The MHB has been in operation for about nine months and has been performing quite well. It has provided the Helios laser fusion facility with additional target illumination flexibility so that many additional parameters can be investigated in the realm of target implosion physics

  3. Design of HELIOS beam diagnostics

    Seagrave, J.D.; Bigio, I.J.; Jackson, S.V.; Laird, A.M.

    1979-01-01

    Verification of satisfactory operation of the HELIOS eight-beam laser system requires measurement of many parameters of each beam on each shot. Fifty-joule samples of each of the eight 1250-J, subnanosecond 34-cm-diameter beams of the HELIOS system are diverted to a gallery of eight folded telescopes and beamsplit to provide diagnostic measurements. Total pulse energy, and prepulse and postlase energy of each beam are measured; pulse shape details and a wavelength spectrum of a selected beam from each shot are measured; and provision is made for retropulse measurement and optical quality monitoring. All data are recorded digitally in a local screen room, with control and communication through a fiberoptic link to the main HELIOS computer

  5. Advances in HELIOS2 nuclear data library

    Wemple, Charles [Studsvik Scandpower, Inc., Iadho Falls, ID (United States); Simeonov, Teodosi [Studsvik Scandpower, Inc., Waltham, MA (United States)

    2017-09-15

    The ongoing development of the HELIOS2 code system at Studsvik includes periodic updates of the nuclear data library. The library expansion includes an update of the cross section data source to ENDF/B-VIIR1, a significant expansion of the burnup chains, the addition of a more complete set of gamma production data, and the development of new resonance treatment options. The goal is to provide the capability for HELIOS2 to more accurately model a wider array of reactor applications and enhance interoperability with SNF, the Studsvik spent fuel analysis code. This paper will also provide a discussion of the nuclear data library benchmarking effort and an overview of other HELIOS2 development efforts.

  6. A Single and Comprehensive Helios Data Archive

    Salem, C. S.

    2017-12-01

    Helios 1 & 2 rank amoung the most important missions in Heliophysics, and the more-than 11 years of data returned by its spacecraft remain of paramount interests to researchers. Their unique trajectories which brought them closer to the Sun than any spaceccraft before or since, enabled their diverse suite of in-situ instruments to return measurements of unprecedented scientific richness. There is however no comprehensive public repository of all Helios in-situ data. Currently, most of the highest resolution data can be obtained from a variety of places, although highly processed and with very little documentation, especially on calibration. Analysis of this data set requires overcoming a number of technical and instrumental issues, knowledge and expertise of which is only possessed by the original PI's of the Helios experiments. We present here a work funded by NASA of aggregating, analyzing, evaluating, documenting and archiving the available Helios 1 and 2 in-situ data. This work at the UC Berkeley Space Sciences Laboratory is being undertaken in close collaboration with colleagues at the University of Koln, at the University of Kiel, at the Imperial College in London and at the Paris Observatory. A careful, detailed, analysis of the Helios fluxgate and search coil magnetic field data as well as plasma data has revealed numerous issues and problems with the available, processed, datasets, that we are still working to solve. We anticipate this comprehensive single archive of all Helios in-situ data, beyond its inherent scientific value, will also be an invaluable asset to the both the Solar Probe Plus and Solar Orbiter missions.

  8. The HELIOS-2 lattice physics code

    Wemple, C.A.; Gheorghiu, H-N.M.; Stamm'ler, R.J.J.; Villarino, E.A.

    2008-01-01

    Major advances have been made in the HELIOS code, resulting in the impending release of a new version, HELIOS-2. The new code includes a method of characteristics (MOC) transport solver to supplement the existing collision probabilities (CP) solver. A 177-group, ENDF/B-VII nuclear data library has been developed for inclusion with the new code package. Computational tests have been performed to verify the performance of the MOC solver against the CP solver, and validation testing against computational and measured benchmarks is underway. Results to-date of the verification and validation testing are presented, demonstrating the excellent performance of the new transport solver and nuclear data library. (Author)

  9. HELIOS: Application for criticality limits assessment

    Simeonov, T.

    2011-01-01

    In the early years, after the discovery of fission, the criticality safety assessment and the established safety limits, have been mainly based on direct experiments. Later, following the advances in the theory, computational methods and computer hardware, theoretical methods have been elaborated to the level to become reliable assessment tools. The computer codes started replacing the experiments, while the experimental data became a valuable validation source for their models. An application of the two-dimensional transport theory code HELIOS for assessment of criticality limits is presented in this paper. The effect of the enrichment, the system dimensions, H/U5 ration and different reflectors were studied in heterogeneous and homogenized systems. Comparisons with published experimental data and evaluated safety limits are made here to demonstrate the range of HELIOS applicability and limitations. (Author)

  10. HELIOS calculations for UO2 lattice benchmarks

    Mosteller, R.D.

    1998-01-01

    Calculations for the ANS UO 2 lattice benchmark have been performed with the HELIOS lattice-physics code and six of its cross-section libraries. The results obtained from the different libraries permit conclusions to be drawn regarding the adequacy of the energy group structures and of the ENDF/B-VI evaluation for 238 U. Scandpower A/S, the developer of HELIOS, provided Los Alamos National Laboratory with six different cross section libraries. Three of the libraries were derived directly from Release 3 of ENDF/B-VI (ENDF/B-VI.3) and differ only in the number of groups (34, 89 or 190). The other three libraries are identical to the first three except for a modification to the cross sections for 238 U in the resonance range

  11. QUADRIGA and KIRKE-front-end applications for HELIOS

    Havluj, F.; Vocka, R.

    2010-01-01

    QUADRIGA and KIRKE are two productivity tools for Studsvik's HELIOS lattice physics code. Their main idea is to shift repetitive and non-creative labor off from the user to a computer program. QUADRIGA is a complex tool for for input file preparation for HELIOS using smart and modular templates, physics models and user-friendly interface, including job launcher and load balancer. It allows non-HELIOS-savvy users to run lattice physics calculations on a computer cluster, offering user-friendly and simple GUI based on dynamically generated forms. The users do not have to know HELIOS and most of the job management is done automatically. KIRKE is a straightforward utility for converting CAD vector drawings into HELIOS geometry descriptions, including automated generation of the computational mesh. It is invaluable for complex, non-repetitive geometries, where HELIOS geometry input is extremely complicated and unimaginably tedious to construct. (Authors)

  14. Relativity experiment on Helios - A status report

    Anderson, J. D.; Melbourne, W. G.; Cain, D. L.; Lau, E. K.; Wong, S. K.; Kundt, W.

    1975-01-01

    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.

  15. Helios: Understanding Solar Evolution Through Text Analytics

    Randazzese, Lucien [SRI International, Menlo Park, CA (United States)

    2016-12-02

    This proof-of-concept project focused on developing, testing, and validating a range of bibliometric, text analytic, and machine-learning based methods to explore the evolution of three photovoltaic (PV) technologies: Cadmium Telluride (CdTe), Dye-Sensitized solar cells (DSSC), and Multi-junction solar cells. The analytical approach to the work was inspired by previous work by the same team to measure and predict the scientific prominence of terms and entities within specific research domains. The goal was to create tools that could assist domain-knowledgeable analysts in investigating the history and path of technological developments in general, with a focus on analyzing step-function changes in performance, or “breakthroughs,” in particular. The text-analytics platform developed during this project was dubbed Helios. The project relied on computational methods for analyzing large corpora of technical documents. For this project we ingested technical documents from the following sources into Helios: Thomson Scientific Web of Science (papers), the U.S. Patent & Trademark Office (patents), the U.S. Department of Energy (technical documents), the U.S. National Science Foundation (project funding summaries), and a hand curated set of full-text documents from Thomson Scientific and other sources.

  18. Measurement of kaons in the Helios experiment

    van Hecke, H.

    1990-01-01

    We have measured kaons and pions in the rapidity interval 0.8--1.3 and p T interval 100--600 MeV/c. We have observed an excess in the ratio of positive kaons to pions over what is expected from p-p for transverse momenta above 300 MeV/c. No such excess is seen for negatives. This excess of K/π increasing with p T has been observed in 14.5 GeV/A Si + Au collisions by E802 at the AGS. Though their data are concentrated at high p T , there is a small region of overlap between the coverage of HELIOS and E802 for p T = 0.4--0.5 GeV/c. In this region the K/π ratios for both positive and negative particles are very similar even though the bombarding energies differ by more than an order of magnitude. We find no strong indication that the rise in K/π above values expected from p-p collisions is higher for high-E T events than for low-E T events

  1. HELIOS: A high intensity chopper spectrometer at LANSCE

    Mason, T.E.; Broholm, C.; Fultz, B.

    1998-01-01

    A proposal to construct a high intensity chopper spectrometer at LANSCE as part of the SPSS upgrade project is discussed. HELIOS will be optimized for science requiring high sensitivity neutron spectroscopy. This includes studies of phonon density of states in small polycrystalline samples, magnetic excitations in quantum magnets and highly correlated electron systems, as well as parametric studies (as a function of pressure, temperature, or magnetic field) of S(Q,ω). By employing a compact design together with the use of supermirror guide in the incident flight path the neutron flux at HELIOS will be significantly higher than any other comparable instrument now operating

  4. Solar wind plasma structure near a 'HELIOS-Perihelion'

    Kikuchi, H.

    1979-01-01

    The purpose of this paper is to introduce a couple of preliminary but important results obtained from HELIOS observation concerning solar wind plasma structure near a ''HELIOS-Perihelion'' among the data analyses in progress, partly in relation to laboratory plasma. Idealized profiles of the bulk velocity, density and temperature of solar wind near 0.3 AU as deduced from HELIOS A data and correlated K-coronal contours were obtained. During 1974 - 1976, the sun was in the period of declining cycle, and the coronal holes expanded to lower latitudes from northern and southern holes. There is general tendency that the northern coronal hole is somewhat larger than the southern coronal hole. In regards to solar wind velocity, there are two fast stream regions with velocity as high as 800 Km/sec. An electron spectrum measured near a HELIOS-Perihelion (0.3 AU) approximately in the solar direction is shown. Three regions can be distinguished in velocity distribution. The density contours of solar wind electrons in velocity space exhibit a narrow beam of electrons in the magnetic field direction close to the plane of observation. (Kato, T.)

  5. HELIOS2: Benchmarking against experiments for hexagonal and square lattices

    Simeonov, T.

    2009-01-01

    HELIOS2, is a 2D transport theory program for fuel burnup and gamma-flux calculation. It solves the neutron and gamma transport equations in a general, two-dimensional geometry bounded by a polygon of straight lines. The applied transport solver may be chosen between: The Method of Collision Probabilities (CP) and The Method of Characteristics(MoC). The former is well known for its successful application for preparation of cross section data banks for 3D simulators for all types lattices for WWERs, PWRs, BWRs, AGRs, RBMK and CANDU reactors. The later, MoC, helps in the areas where the requirements of CP for computational power become too large of practical application. The application of HELIOS2 and The Method of Characteristics for some large from calculation point of view benchmarks is presented in this paper. The analysis combines comparisons to measured data from the Hungarian ZR-6 reactor and JAERI facility of Tank type Critical Assembly (TCA) to verify and validate HELIOS2 and MOC for WWER assembly imitators; configurations with different absorber types- ZrB 2 , B 4 C, Eu 2 O 3 and Gd 2 O 3 ; and critical configurations with stainless steel in the reflector. Core eigenvalues and reaction rates are compared. With the account for the uncertainties the results are generally excellent. Special place in this paper is given to the effect of Iron-made radial reflector. Comparisons to measurements from TIC and TCA for stainless steel and Iron reflected cores are presented. The calculated by HELIOS-2 reactivity effect is in very good agreement with the measurements. (author)

  7. Automatic target alignment of the Helios laser system

    Liberman, I.; Viswanathan, V.K.; Klein, M.; Seery, B.D.

    1980-01-01

    An automatic target-alignment technique for the Helios laser facility is reported and verified experimentally. The desired alignment condition is completely described by an autocollimation test. A computer program examines the autocollimated return pattern from the surrogate target and correctly describes any changes required in mirror orientation to yield optimum targe alignment with either aberrated or misaligned beams. Automated on-line target alignment is thus shown to be feasible

  9. Pereira's attack on legalizing euthanasia or assisted suicide: smoke and mirrors.

    Downie, J; Chambaere, K; Bernheim, J L

    2012-06-01

    To review the empirical claims made in: Pereira J. Legalizing euthanasia or assisted suicide: the illusion of safeguards and controls. Curr Oncol 2011;18:e38-45. We collected all of the empirical claims made by Jose Pereira in "Legalizing euthanasia or assisted suicide: the illusion of safeguards and controls." We then collected all reference sources provided for those claims. We compared the claims with the sources (where sources were provided) and evaluated the level of support, if any, the sources provide for the claims. We also reviewed other available literature to assess the veracity of the empirical claims made in the paper. We then wrote the present paper using examples from the review. Pereira makes a number of factual statements without providing any sources. Pereira also makes a number of factual statements with sources, where the sources do not, in fact, provide support for the statements he made. Pereira also makes a number of false statements about the law and practice in jurisdictions that have legalized euthanasia or assisted suicide. Pereira's conclusions are not supported by the evidence he provided. His paper should not be given any credence in the public policy debate about the legal status of assisted suicide and euthanasia in Canada and around the world.

  10. To José Pereira Lages, our friend and colleague

    2005-01-01

    It was with great sadness that we learnt of the accidental demise of our colleague, José Pereira Lages, whilst he was transporting equipment for the LHC. José was the team leader for the LHC's general services at points 1 and 8, working on behalf of the firm DBS Transports. Determined and receptive, always ready to help those around him, he always did his best in his work. His smile, his kindness and his professionalism made him somebody who was unanimously appreciated, whether it was by his colleagues at DBS, his colleagues at CERN or any of the CERN users that he encountered. He leaves behind a large gap in our midst and we will all miss him. We will be reminded of his smile in this picture from the last issue of the Bulletin, taken to celebrate his win in the French Championships for fork-lift truck unloading. It was only a few days ago that we were so happy and proud of him, looking forward, in our minds, to the future competitions that lay ahead. We share the grief of his family and all his friend...

  11. Helios Prototype on lakebed during ground check of electric motors

    1999-01-01

    The Helios Prototype is an enlarged version of the Centurion flying wing, which flew a series of test flights at Dryden in late 1998. The craft has a wingspan of 247 feet, 41 feet greater than the Centurion, 2 1/2 times that of its solar-powered Pathfinder flying wing, and longer than either the Boeing 747 jetliner or Lockheed C-5 transport aircraft. Helios is one of several remotely-piloted aircraft-also known as uninhabited aerial vehicles or UAV's-being developed as technology demonstrators by several small airframe manufacturers under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project. Developed by AeroVironment, Inc., of Monrovia, Calif., the unique craft is intended to demonstrate two key missions: the ability to reach and sustain horizontal flight at 100,000 feet altitude on a single-day flight, and to maintain flight above 50,000 feet altitude for at least four days, both on electrical power derived from non-polluting solar energy. During later flights, AeroVironment's flight test team will evaluate new motor-control software which may allow the pitch of the aircraft-the nose-up or nose-down attitude in relation to the horizon-to be controlled entirely by the motors. If successful, productions versions of the Helios could eliminate the elevators on the wing's trailing edge now used for pitch control, saving weight and increasing the area of the wing available for installation of solar cells.

  12. VENUS-2 Benchmark Problem Analysis with HELIOS-1.9

    Jeong, Hyeon-Jun; Choe, Jiwon; Lee, Deokjung

    2014-01-01

    Since there are reliable results of benchmark data from the OECD/NEA report of the VENUS-2 MOX benchmark problem, by comparing benchmark results users can identify the credibility of code. In this paper, the solution of the VENUS-2 benchmark problem from HELIOS 1.9 using the ENDF/B-VI library(NJOY91.13) is compared with the result from HELIOS 1.7 with consideration of the MCNP-4B result as reference data. The comparison contains the results of pin cell calculation, assembly calculation, and core calculation. The eigenvalues from those are considered by comparing the results from other codes. In the case of UOX and MOX assemblies, the differences from the MCNP-4B results are about 10 pcm. However, there is some inaccuracy in baffle-reflector condition, and relatively large differences were found in the MOX-reflector assembly and core calculation. Although HELIOS 1.9 utilizes an inflow transport correction, it seems that it has a limited effect on the error in baffle-reflector condition

  13. Comportamiento del Helio en estrellas químicamente peculiares

    Malaroda, S. M.; López García, Z.; Leone, F.; Catalano, F.

    Las estrellas químicamente peculiares (CP) se caracterizan por tener deficiencias y sobreabundancias de algunos elementos químicos de hasta 106 veces la abundancia solar. Además presentan variaciones en las líneas espectrales. Se piensa que ello se debe a que los campos magnéticos presentes en este tipo de estrellas son principalmente dipolares, con un eje de simetría diferente del eje de rotación. La distribución de los elementos sobreabundantes y deficientes no es homogénea sobre la superficie estelar y las variaciones observadas serían una consecuencia directa de la rotación estelar. Entre los elementos con abundancia anómala se encuentra el Helio, cuyas líneas tienen intensidades que no son consistentes con una abundancia normal, que no puede ser determinada del modo usual, o sea, considerando una atmósfera con composición solar. Con el fin de determinar la abundancia de este elemento, se inició un estudio de estrellas anómalas de Helio, Hew y He strong. Además se determinarán las abundancias de otros elementos anómalos como ser el Si, Cr, Mg, Mn y Fe. Las mismas se determinan del modo tradicional, o sea: a) medida de los anchos equivalentes de las líneas de los distintos elementos analizados; b) adopción de la temperatura efectiva, gravedad y abundancia del Helio; c) cálculo del modelo de atmósfera d) comparación con las observaciones y reinicio de un proceso iterativo hasta lograr un acuerdo entre todos los parámetros analizados. Las observaciones se llevaron a cabo en el Complejo Astronómico El Leoncito. Se observaron setenta y ocho estrellas anómalas de Helio. En este momento se está procediendo a calcular las abundancias correspondientes a los distintos elementos químicos. Para ello se hace uso de los modelos de Kurucz, ATLAS9. Los cálculos NLTE de las líneas de Helio se llevan a cabo con el programa MULTI y se compararán con los realizados con el programa WIDTH9 de Kurucz (LTE), con el objeto de resaltar la importancia de

  14. Evolución de estrellas de Helio

    Panei, J. A.; Benvenuto, O. G.; Althaus, L. G.

    Podríamos identificar a las estrellas de helio con estrellas Wolf-Rayet (WR) que han perdido su envoltura rica en hidrógeno ya sea porque las mismas pertenecen a sistemas binarios o a través de fuertes vientos estelares. Las WR representan una etapa evolucionaria normal de las estrellas masivas, cuya pérdida de masa es >= 3 × 10-5Msolar/yr y la cual es sufrida por la estrella en un tiempo de escala mucho menor que el tiempo en que se produce la quema del He. Esto garantiza la ``homogeneidad'' de las estrellas de helio para nuestros modelos. Este tipo de estrellas serían posibles progenitores de SN tipo Ib y Ic. Aquí presentamos un estudio sobre la evolución de estrellas de helio a partir de la secuencia principal de helio, pasando por el flash de carbono, hasta agotarlo en la región central; como así también la dependencia con la variable masa y con la pérdida de la misma para distintos tipos de masas. Para tal fin hemos utilizado un código de evolución estelar completo que realiza todas las reacciones de Fowler en forma simultánea. También se han tenido en cuenta los procesos de mezcla convectiva, los principales mecanismos de emisión de neutrinos y los efectos de la pérdida de masa. Las opacidades utilizadas fueron las de Rogers & Iglesias (1992). Debido a la pérdida de masa en este tipo de estrellas, hemos encontrado que los perfiles convectivos, la composición química, las condiciones centrales de temperatura y presión, luminosidad y temperatura efectiva dependen en forma esencial de la velocidad de pérdida de masa adoptada, lo que tendría profundas implicaciones en la evolución posterior de estos objetos.

  15. AeroVironment technician checks a Helios solar cell panel

    2000-01-01

    A technician at AeroVironment's Design Development Center in Simi Valley, California, checks a panel of silicon solar cells for conductivity and voltage. The bi-facial cells, fabricated by SunPower, Inc., of Sunnyvale, California, are among 64,000 solar cells which have been installed on the Helios Prototype solar-powered aircraft to provide power to its 14 electric motors and operating systems. Developed by AeroVironment under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project, the Helios Prototype is the forerunner of a planned fleet of slow-flying, long duration, high-altitude aircraft which can perform atmospheric science missions and serve as telecommunications relay platforms in the stratosphere. Target goals set by NASA for the giant 246-foot span flying wing include reaching and sustaining subsonic horizontal flight at 100,000 feet altitude in 2001, and sustained continuous flight for at least four days and nights above 50,000 feet altitude with the aid of a regenerative fuel cell-based energy storage system now under development in 2003.

  16. Comet West: a view from the HELIOS zodiacal light photometers

    Benensohn, R.M.; Jackson, B.V.

    1987-01-01

    Comet West passed through perihelion on February 25, 1976. The comet crossed the HELIOS A and B spacecraft zodiacal light photometer fields of view as the spacecraft orbited the Sun, allowing them to record the brightness, polarization, and color of the comet and its surrounding interplanetary medium. Data from the U, B, and V photometers across the tail shows a distinct bluing followed by a slight reddening corresponding to the ion and dust tails, respectively, entering the field of view. The non-Earth perspective of the HELIOS photometers allows a comparison of the tail with Earth observations at the same time. Precise location of the nucleus and tail allow the photometer data to be searched for evidence of the comet bow shock and orbital dust. A brightness bump present in the data before the comet reaches some photometer positions, can be shown to approximately form a parabolic shape Sunward and ahead of the orbital motion of the Comet West nucleus. If this is the comet bow shock or bow compression, then it corresponds to a density enhancement of the ambient medium by 1.5 to 2 times in the vicinity of the comet. The distance of the brightness increase from the nucleus by comparison with Comet Halley implies a neutral gas production rate of approximately 3 times that of Halley

  17. HELIOS-CR - A 1-D radiation-magnetohydrodynamics code with inline atomic kinetics modeling

    MacFarlane, J.J.; Golovkin, I.E.; Woodruff, P.R.

    2006-01-01

    HELIOS-CR is a user-oriented 1D radiation-magnetohydrodynamics code to simulate the dynamic evolution of laser-produced plasmas and z-pinch plasmas. It includes an in-line collisional-radiative (CR) model for computing non-LTE atomic level populations at each time step of the hydrodynamics simulation. HELIOS-CR has been designed for ease of use, and is well-suited for experimentalists, as well as graduate and undergraduate student researchers. The energy equations employed include models for laser energy deposition, radiation from external sources, and high-current discharges. Radiative transport can be calculated using either a multi-frequency flux-limited diffusion model, or a multi-frequency, multi-angle short characteristics model. HELIOS-CR supports the use of SESAME equation of state (EOS) tables, PROPACEOS EOS/multi-group opacity data tables, and non-LTE plasma properties computed using the inline CR modeling. Time-, space-, and frequency-dependent results from HELIOS-CR calculations are readily displayed with the HydroPLOT graphics tool. In addition, the results of HELIOS simulations can be post-processed using the SPECT3D Imaging and Spectral Analysis Suite to generate images and spectra that can be directly compared with experimental measurements. The HELIOS-CR package runs on Windows, Linux, and Mac OSX platforms, and includes online documentation. We will discuss the major features of HELIOS-CR, and present example results from simulations

    2007-05-15

    This report presents a study comparing deterministic lattice physics calculations with Monte Carlo calculations for LWR fuel pin and assembly problems. The study has focused on comparing results from the lattice physics code CASMO-3 and HELIOS against those from the continuous-energy Monte Carlo code McCARD. The comparisons include k{sub inf}, isotopic number densities, and pin power distributions. The CASMO-3 and HELIOS calculations for the k{sub inf}'s of the LWR fuel pin problems show good agreement with McCARD within 956pcm and 658pcm, respectively. For the assembly problems with Gadolinia burnable poison rods, the largest difference between the k{sub inf}'s is 1463pcm with CASMO-3 and 1141pcm with HELIOS. RMS errors for the pin power distributions of CASMO-3 and HELIOS are within 1.3% and 1.5%, respectively.

  20. Helios, and not FoxP3, is the marker of activated Tregs expressing GARP/LAP.

    Elkord, Eyad; Abd Al Samid, May; Chaudhary, Belal

    2015-08-21

    Regulatory T cells (Tregs) are key players of immune regulation/dysregulation both in physiological and pathophysiological settings. Despite significant advances in understanding Treg function, there is still a pressing need to define reliable and specific markers that can distinguish different Treg subpopulations. Herein we show for the first time that markers of activated Tregs [latency associated peptide (LAP) and glycoprotein A repetitions predominant (GARP, or LRRC32)] are expressed on CD4+FoxP3- T cells expressing Helios (FoxP3-Helios+) in the steady state. Following TCR activation, GARP/LAP are up-regulated on CD4+Helios+ T cells regardless of FoxP3 expression (FoxP3+/-Helios+). We show that CD4+GARP+/-LAP+ Tregs make IL-10 immunosuppressive cytokine but not IFN-γ effector cytokine. Further characterization of FoxP3/Helios subpopulations showed that FoxP3+Helios+ Tregs proliferate in vitro significantly less than FoxP3+Helios- Tregs upon TCR stimulation. Unlike FoxP3+Helios- Tregs, FoxP3+Helios+ Tregs secrete IL-10 but not IFN-γ or IL-2, confirming they are bona fide Tregs with immunosuppressive characteristics. Taken together, Helios, and not FoxP3, is the marker of activated Tregs expressing GARP/LAP, and FoxP3+Helios+ Tregs have more suppressive characteristics, compared with FoxP3+Helios- Tregs. Our work implies that therapeutic modalities for treating autoimmune and inflammatory diseases, allergies and graft rejection should be designed to induce and/or expand FoxP3+Helios+ Tregs, while therapies against cancers or infectious diseases should avoid such expansion/induction.

  1. Alternative Splice Variants Modulates Dominant-Negative Function of Helios in T-Cell Leukemia.

    Shaorong Zhao

    Full Text Available The molecular defects which lead to multistep incidences of human T-cell leukemia have yet to be identified. The DNA-binding protein Helios (known as IKZF2, a member of the Ikaros family of Krüppel-like zinc-finger proteins, functions pivotally in T-cell differentiation and activation. In this study, we identify three novel short Helios splice variants which are T-cell leukemic specific, and demonstrate their dominant-negative function. We then test the cellular localization of distinct Helios isoforms, as well as their capability to form heterodimer with Ikaros, and the association with complexes comprising histone deacetylase (HDAC. In addition, the ectopic expression of T-cell leukemic Helios isoforms interferes with T-cell proliferation and apoptosis. The gene expression profiling and pathway analysis indicated the enrichment of signaling pathways essential for gene expression, translation, cell cycle checkpoint, and response to DNA damage stimulus. These data indicate the molecular function of Helios to be involved in the leukemogenesis and phenotype of T-cell leukemia, and also reveal Helios deregulation as a novel marker for T-cell leukemia.

  3. Helios expression in regulatory T cells promotes immunosuppression, angiogenesis and the growth of leukemia cells in pediatric acute lymphoblastic leukemia.

    Li, Xue; Li, Dong; Huang, Xiaoyang; Zhou, Panpan; Shi, Qing; Zhang, Bing; Ju, Xiuli

    2018-04-01

    Regulatory T cells (Tregs) characterized by the transcription factor forkhead box P3 (FoxP3) are crucial for maintaining immune tolerance and preventing autoimmunity. However, FoxP3 does not function alone and Helios is considered a potential candidate for defining Treg subsets. In this study, we investigated the expression and function of Helios for identifying Tregs in childhood precursor B-cell acute lymphoblastic leukemia (pre-B ALL). Our results demonstrated that patients with pre-B ALL had a higher percentage of Helios + FoxP3 + CD4 + Tregs. And there was a positive correlation between the expression of Helios and the suppressive function of Tregs, the risk gradation of ALL. Helios in combination with CD4 and FoxP3 may be an effective way to detect functional Tregs in pre-B ALL by promoting the secretion of transforming growth factor (TGF)-β1. Furthermore, Helios + Tregs could regulate angiogenesis in the BM niche of pre-B ALL via the VEGFA/VEGFR2 pathway. We also found Helios + Tregs decreased apoptosis rate of nalm-6 cells by up-regulating the expression of anti-apoptosis protein Bcl-2. In summary, these data strongly imply the physiological importance of Helios expression in Tregs, and suggest that the manipulation of Helios may serve as a novel strategy for cancer immunotherapy.

  4. Gaseous saturable absorbers for the Helios CO2 laser system

    Haglund, R.F. Jr.; Nowak, A.V.; Czuchlewski, S.J.

    1981-01-01

    Saturable absorbers are widely used to suppress parasitic oscillations in large-aperture, high-power CO 2 fusion-laser systems. We report experimental results on SF 6 -based gaseous saturable absorbers used for parasitic suppression in the eight-beam, 10 kJ Helios fusion-laser system. The gas mix effectively quenches self-lasing in the 9 and 10 μm branches of the CO 2 laser spectrum while simultaneously allowing high transmission of subnanosecond multiwavelength pulses for target-irradiation experiments. The gas isolator now in use consists of SF 6 and the additional fluorocarbons: 1, 1-difluoroethane (FC-152a); dichlorodifluoromethane (FC-12); chloropentafluoroethane (FC-115); 1,1-dichloro 2,2-difluoroethylene (FC-1112a); chlorotrifluoroethylene (FC-1113); and perfluorocyclobutane (FC-C318). The saturation of the mix was studied as a function of incident fluence, pressure, cell length, and incident wavelength. Experimental results are presented on the saturation properties of pure SF 6 and FC-152a and compared with the saturation behavior of CO 2 at 400 0 C

    2004-01-01

    To verify the HELIOS-MASTER computer code system for a nuclear design, we have been performed benchmark calculations for various reactor cores. The Halden reactor is a boiling, heavy water moderated reactor. At a full power of 18-20MWt, the moderator temperature is 240 .deg. C and the pressure is 33 bar. This study describes the verification of the HELIOS-MASTER computer code system for a nuclear design and the analysis of a hexagonal and D 2 O moderated core through a benchmark of the Halden reactor core. HELIOS, developed by Scandpower A/S, is a two-dimensional transport program for the generation of group cross-sections, and MASTER, developed by KAERI, is a three-dimensional nuclear design and analysis code based on the two-group diffusion theory. It solves the neutronics model with the TPEN (Triangle based Polynomial Expansion Nodal) method for a hexagonal geometry

    The HELIOS-MASTER code system is verified through the benchmark of the critical experiments that were performed by RRC 'Kurchatov Institute' with water-moderated hexagonally pitched lattices of highly enriched Uranium fuel rods (80w/o). We also used the same input by using the MCNP code that was described in the evaluation report, and compared our results with those of the evaluation report. HELIOS, developed by Scandpower A/S, is a two-dimensional transport program for the generation of group cross-sections, and MASTER, developed by KAERI, is a three-dimensional nuclear design and analysis code based on the two-group diffusion theory. It solves neutronics model with the AFEN (Analytic Function Expansion Nodal) method for hexagonal geometry. The results show that the HELIOS-MASTER code system is fast and accurate enough to be used as nuclear core analysis tool for hexagonal geometry

  9. The Philosophy of User Interfaces in HELIO and the Importance of CASSIS

    Bonnin, X.; Aboudarham, J.; Renié, C.; Csillaghy, A.; Messerotti, M.; Bentley, R. D.

    2012-09-01

    HELIO is a European project funded under FP7 (Project No. 238969). One of its goals as a Heliospheric Virtual Observatory is to provide an easy access to many datasets scattered all over the world, in the fields of Solar physics, Heliophysics, and Planetary magnetospheres. The efficiency of such a tool is very much related to the quality of the user interface. HELIO infrastructure is based on a Service Oriented Architecture (SOA), regrouping a network of standalone components, which allows four main types of interfaces: - HELIO Front End (HFE) is a browser-based user interface, which offers a centralized access to the HELIO main functionalities. Especially, it provides the possibility to reach data directly, or to refine selection by determination of observing characteristics, such as which instrument was observing at that time, which instrument was at this location, etc. - Many services/components provide their own standalone graphical user interface. While one can directly access individually each of these interfaces, they can also be connected together. - Most services also provide direct access for any tools through a public interface. A small java library, called Java API, simplifies this access by providing client stubs for services and shields the user from security, discovery and failover issues. - Workflows capabilities are available in HELIO, allowing complex combination of queries over several services. We want the user to be able to navigate easily, at his needs, through the various interfaces, and possibly use a specific one in order to make much-dedicated queries. We will also emphasize the importance of the CASSIS project (Coordination Action for the integration of Solar System Infrastructure and Science) in encouraging the interoperability necessary to undertake scientific studies that span disciplinary boundaries. If related projects follow the guidelines being developed by CASSIS then using external resources with HELIO will be greatly simplified.

  12. Volume simplicity constraint in the Engle-Livine-Pereira-Rovelli spin foam model

    Bahr, Benjamin; Belov, Vadim

    2018-04-01

    We propose a quantum version of the quadratic volume simplicity constraint for the Engle-Livine-Pereira-Rovelli spin foam model. It relies on a formula for the volume of 4-dimensional polyhedra, depending on its bivectors and the knotting class of its boundary graph. While this leads to no further condition for the 4-simplex, the constraint becomes nontrivial for more complicated boundary graphs. We show that, in the semiclassical limit of the hypercuboidal graph, the constraint turns into the geometricity condition observed recently by several authors.

  20. Deformation of the Engle-Livine-Pereira-Rovelli spin foam model by a cosmological constant

    Bahr, Benjamin; Rabuffo, Giovanni

    2018-04-01

    In this article, we consider an ad hoc deformation of the Engle-Livine-Pereira-Rovelli model for quantum gravity by a cosmological constant term. This sort of deformation was first introduced by Han for the case of the 4-simplex. In this article, we generalize the deformation to the case of arbitrary vertices, and compute its large-j asymptotics. We show that, if the boundary data correspond to a four-dimensional polyhedron P , then the asymptotic formula gives the usual Regge action plus a cosmological constant term. We pay particular attention to the determinant of the Hessian matrix, and show that it can be related to that of the undeformed vertex.

  1. Evolución de estrellas enanas blancas de Helio de masa baja e intermedia

    Althaus, L. G.; Benvenuto, O. G.

    Numerosas observaciones realizadas particularmente en los últimos dos años parecen confirmar que las enanas blancas (EB) de helio de masa baja e intermedia son el resultado de la evolución de sistemas binarios cercanos. Con el objeto de realizar una adecuada interpretación de estos objetos son necesarios modelos de EBs de helio lo más detallado posibles. En este estudio presentamos cálculos detallados de la evolución de EBs de helio con masas entre M=0.1Msolar y M=0.5Msolar a intervalos de 0.05Msolar . Para ello, hemos tenido en cuenta los efectos de temperatura finita mediante un código de evolución estelar lo más actualizado posible. En particular, el transporte de energía es descripto en el marco del nuevo modelo para la convección turbulenta desarrollado por Canuto - Mazzitelli. Además hemos considerado la nueva ecuación de estado para plasmas de helio de Saumon et al. y nuevas opacidades radiativas OPAL. Las pérdidas por neutrinos fueron asimismo tenidas en cuenta. Excepto para las EBs más masivas, nuestros modelos iniciales están ubicados en las cercanías de la correspondiente línea de Hayashi para configuraciones de helio. Nuestros resultados muestran que existe una región prohibida en el diagrama observacional HR donde ninguna EB de helio puede encontrarse. Dicha región es para log{(L/Lsolar )}>= -0.25 and log{Teff} >= 4.45. Hemos encontrado también que los tracks evolutivos en el diagrama HR en el dominio de alta luminosidad (pre - EB) son fuertemente afectados por la eficiencia convectiva y que las pérdidas por neutrinos son importantes en los modelos más masivos. Finalmente hemos analizado la estructura de la zona convectiva externa encontrando que la teoría de Canuto - Mazzitelli conduce a un perfil convectivo muy diferente del dado por cualquier versión de la popular teoría de la mixing length. Si bién este comportamiento es decisivo en el contexto de las inestabilides pulsacionales, los radios y gravedades superficiales de

  2. 3D heterogeneous transport calculations of CANDU fuel with EVENT/HELIOS

    Rahnema, F.; Mosher, S.; Ilas, D.; De Oliveira, C.; Eaton, M.; Stamm'ler, R.

    2002-01-01

    The applicability of the EVENT/HELIOS package to CANDU lattice cell analysis is studied in this paper. A 45-group cross section library is generated using the lattice depletion transport code HELIOS. This library is then used with the 3-D transport code EVENT to compute the pin fission densities and the multiplication constants for six configurations typical of a CANDU cell. The results are compared to those from MCNP with the same multigroup library. Differences of 70-150 pcm in multiplication constant and 0.08-0.95% in pin fission density are found for these cases. It is expected that refining the EVENT calculations can reduce these differences. This gives confidence in applying EVENT to transient analyses at the fuel pin level in a selected part of a CANDU core such as the limiting bundle during a loss of coolant accident (LOCA). (author)

  3. The interactions of the HELIOS probe with the solar wind plasma

    Voigt, G.H.; Isensee, U.; Maassberg, H.

    1981-08-01

    HELIOS solar probe disturbs the solar wind plasma in the near vicinity. Around the probe, a space charge cloud is formed due to strong photoelectron emission and fade out of solar wind particles. The conducting and isolating parts of the surface are differently charged. These effects result in a very complex potential structure in the vicinity of the probe and on the surface. The interactions of the HELIOS probe with the solar wind plasma are described by models based on kinetic theory of plasma. The combination of these models yields an entire and consistent representation of the spacecraft charging and the potential structure. Electron spectra measured by plasma experiment E1 are analysed and compared with results of the theoretical models. (orig.) [de

  4. An Adaptation of the HELIOS/MASTER Code System to the Analysis of VHTR Cores

    Noh, Jae Man; Lee, Hyun Chul; Kim, Kang Seog; Kim, Yong Hee

    2006-01-01

    KAERI is developing a new computer code system for an analysis of VHTR cores based on the existing HELIOS/MASTER code system which was originally developed for a LWR core analysis. In the VHTR reactor physics, there are several unique neutronic characteristics that cannot be handled easily by the conventional computer code system applied for the LWR core analysis. Typical examples of such characteristics are a double heterogeneity problem due to the particulate fuels, the effects of a spectrum shift and a thermal up-scattering due to the graphite moderator, and a strong fuel/reflector interaction, etc. In order to facilitate an easy treatment of such characteristics, we developed some methodologies for the HELIOS/MASTER code system and tested their applicability to the VHTR core analysis

    Song, Jae Seung; Kim, J. C.; Cho, B. O. [Korea Atomic Energy Research Institute, Taejon (Korea)

    1999-03-01

    A nuclear design system HELIOS/MASTER was established and core follow calculations were performed for Yonggwang Unit 1 cycles 1 through 7 and Yonggwang Unit 3 cycles 1 through 2. The accuracy of HELIOS/MASTER system was evaluated by estimations of uncertainties of reactivity and peaking factors and by comparisons of the maximum differences of isothermal temperature coefficient, inverse boron worth and control rod worth with the CASMO-3/MASTER uncertainties. The reactivity uncertainty was estimated by 362 pcm, and the uncertainties of three-dimensional, axially integrated radial, and planar peaking factors were evaluated by 0.048, 0.034, and 0.044 in relative power unit, respectively. The maximum differences of isothermal temperature coefficient, inverse boron worth and control rod worth were within the CASMO-3/MASTER uncertainties. 17 refs., 17 figs., 10 tabs. (Author)

    Volland, H.; Bird, M. K.; Levy, G. S.; Stelzried, C. T.; Seidel, B. L.

    1977-01-01

    The first of two solar occultations of the satellite Helios-1 in 1975 occurred in April when the satellite's ray path approached the west limb of the sun to a minimum distance of 1.63 solar radii. The second occultation took place in late August/early September when Helios-1 was totally eclipsed by the photosphere. Measurements of the polarization angle of the linearly polarized telemetry signal were performed with automatic tracking polarimeters at the 64 m Goldstone Tracking Station in California and also at the 100 m radio telescope in Effelsberg, West Germany. The coronal Faraday rotation as a function of the solar offset for both occultations is shown in graphs. The theoretical significance of the observations is investigated.

    2005-01-01

    The latest research associated with the very high temperature gas-cooled reactor (VHTR) is focused on the verification of a system performance and safety under operating conditions for the VHTRs. As a part of those, an international gas-cooled reactor program initiated by IAEA is going on. The key objectives of this program are the validation of analytical computer codes and the evaluation of benchmark models for the projected and actual VHTRs. New reactor physics analysis procedure for the prismatic VHTR is under development by adopting the conventional two-step procedure. In this procedure, a few group constants are generated through the transport lattice calculations using the HELIOS code, and the core physics analysis is performed by the 3-dimensional nodal diffusion code MASTER. We evaluated the performance of the HELIOS/MASTER code package through the benchmark calculations related to the GT-MHR (Gas Turbine-Modular Helium Reactor) to dispose weapon plutonium. In parallel, MCNP is employed as a reference code to verify the results of the HELIOS/MASTER procedure

    Full Text Available Why the ideas of discipline, rigidity, detachment between the educator and the educating still are so exalted in our society? Why are they still are directly associated with the learning? Are there no other ways of the learning happen and which may be more effective than this traditional models? These were the main concerns that guide us to elaborate this article. The group PET Conexão de Saberes - Música do Oprimido (Program of Tutorial Education/Connection of knowledge - Music of the Oppressed - UnB performed in the period from 16 May to 11 July 2015 body percussion workshops at the Municipal School Aleixo Pereira Braga II (Cidade Ocidental-GO. We lived with a group of kids during the Saturdays by the morning and realized that this musical activity began a dynamic environment of learning based on the collectivity, playfulness and affectivity. The children assimilate the workshops as plays and felt free to take risks, experiment and learn about music. Thus, this experience with children of Cidade Ocidental made us reflect about the role of the affectivity in the Child Education basing ourselves in articles of Developmental Psychology area and the Social-Emotional Education.

    Jain, Rohit; Biedron, Robert T.; Jones, William T.; Lee-Rausch, Elizabeth M.

    2016-01-01

    Under a recent collaborative effort between the US Army Aeroflightdynamics Directorate (AFDD) and NASA Langley, NASA's general unstructured CFD solver, FUN3D, was modularized as a CREATE-AV Helios near-body unstructured grid solver. The strategies adopted in Helios/FUN3D integration effort are described. A validation study of the new capability is performed for rotorcraft cases spanning hover prediction, airloads prediction, coupling with computational structural dynamics, counter-rotating dual-rotor configurations, and free-flight trim. The integration of FUN3D, along with the previously integrated NASA OVERFLOW solver, lays the ground for future interaction opportunities where capabilities of one component could be leveraged with those of others in a relatively seamless fashion within CREATE-AV Helios.

  14. Empirical models of the Solar Wind : Extrapolations from the Helios & Ulysses observations back to the corona

    Maksimovic, M.; Zaslavsky, A.

    2017-12-01

    We will present extrapolation of the HELIOS & Ulysses proton density, temperature & bulk velocities back to the corona. Using simple mass flux conservations we show a very good agreement between these extrapolations and the current state knowledge of these parameters in the corona, based on SOHO mesurements. These simple extrapolations could potentially be very useful for the science planning of both the Parker Solar Probe and Solar Orbiter missions. Finally will also present some modelling considerations, based on simple energy balance equations which arise from these empirical observationnal models.

    The presented analyses provide information about the suitability of the lattice burnup code HELIOS and the recently developed code SCALE/TRITON for the prediction of isotopic compositions of high burnup LWR fuel. The accurate prediction of the isotopic inventory of high burnt spent fuel is a prerequisite for safety analyses in and outside of the reactor core, safe loading of spent fuel into storage casks, design of next generation spent fuel casks and for any consideration of burnup credit. Depletion analyses are performed with both burnup codes for PWR and BWR fuel samples which were irradiated far beyond 50 GWd/t within the LWR-PROTEUS Phase II project. (orig.)

  16. HelioTrope: An innovative and efficient prototype for solar power production

    Papageorgiou George

    2014-01-01

    Full Text Available The solar energy alternative could provide us with all the energy we need as it exist in vast quantities all around us. We only should be innovative enough in order to improve the efficiency of our systems in capturing and converting solar energy in usable forms of power. By making a case for the solar energy alternative, we identify areas where efficiency can be improved and thereby Solar Energy can become a competitive energy source. This paper suggests an innovative approach to solar energy power production, which is manifested in a prototype given the name HelioTrope. The Heliotrope Solar Energy Production prototype is tested on its' capabilities to efficiently covert solar energy to generation of electricity and other forms of energy for storage or direct use. HelioTrope involves an innovative Stirling engine design and a parabolic concentrating dish with a sun tracking system implementing a control algorithm to maximize the capturing of solar energy. Further, it utilizes a patent developed by the authors where a mechanism is designed for the transmission of reciprocating motion of variable amplitude into unidirectional circular motion. This is employed in our prototype for converting linear reciprocating motion into circular for electricity production, which gives a significant increase in efficiency and reduces maintenance costs. Preliminary calculations indicate that the Heliotrope approach constitutes a competitive solution to solar power production.

    Technician Marshall MacCready carefully lays a panel of solar cells into place on a wing section of the Helios Prototype flying wing at AeroVironment's Design Development Center in Simi Valley, California. The bi-facial cells, manufactured by SunPower, Inc., of Sunnyvale, California, are among 64,000 solar cells which have been installed on the solar-powered aircraft to provide electricity to its 14 motors and operating systems. Developed by AeroVironment under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project, the Helios Prototype is the forerunner of a planned fleet of slow-flying, long duration, high-altitude aircraft which can perform atmospheric science missions and serve as telecommunications relay platforms in the stratosphere. Target goals set by NASA for the giant 246-foot span flying wing include reaching and sustaining subsonic horizontal flight at 100,000 feet altitude in 2001, and sustained continuous flight for at least four days and nights above 50,000 feet altitude 2003 with the aid of a regenerative fuel cell-based energy storage system now being developed.

    2016-01-01

    In places such as nuclear power plant disaster area, which it is difficult for human workers to enter, robots are required to scout those places instead of human workers. In this paper, we present a mobile manipulator HELIOS X for a nuclear plant decommissioning task. Firstly, we address demands and specifications for the robot, considering the mission of reconnaissance. Then we outline the system of the robot, mainly focusing on the following mechanism: 'Crank Wheel', 'Main Arm', 'Sphere Link Wrist', 'Camera Arm', 'Control System' and 'System architecture'. Especially, we installed 3 degree of freedom 'Camera Arm' on the 'Main Arm', in order to improve functionality of remote control system. This enables the operator to monitor both the gripper and its overall view of the robot. 'Camera Arm' helps the operator to recognize the distance from an object to the gripper, because the operator can interactively move the viewpoint of the camera, and monitor from another camera angle without changing the gripper's position. We confirmed the basic functionality of mobile base, 'Main Arm' and 'Camera Arm' through hardware experiments. We also demonstrated that HELIOS X could pass through the pull-to-open door with a substantial closing force when the operator watched camera view only. (author)

  1. On the influence of spatial discretization on cross section preparation with HELIOS 1.9

    Merk, B.; Koch, R.

    2008-01-01

    The aim of many reactor calculations is the determination of the neutron flux and the nuclear power distribution. These distributions are in general calculated by solving the space and energy dependent static transport equation. Thus, a reliable computation of the neutron flux distribution within the reactor core would require the solution of the space-, energy- and angle-dependent neutron transport equation for the full nuclear reactor core. It is not yet feasible to solve exactly the neutron transport equation for realistic reactor core geometries in detail in practical use. Thus deterministic reactor calculations are split into the cell and lattice calculation based on static transport and the core simulation based on nodal codes. The cell and lattice calculations are mostly based on multi group transport calculations within two dimensions considering unstructured meshes. The resulting neutron flux is used for the preparation of few group cross sections like they are used in the nodal 3D full core simulation codes. One commercial standard product is the Studsvik Scandpower code system HELIOS 1.9. ''The transport method of HELIOS is called the CCCP method, because it is based on current coupling and collision probabilities (first-flight probabilities).. the system to be calculated consists of space elements that are coupled with each other and with the boundaries by interface currents, while the properties of each space element - its responses to sources and in-currents - are obtained from collision probabilities'' [ 1]. The applied collision probabilities method is based on the flat flux approximation. ''We assume that particles are emitted isotropically and uniformly within each discrete volume. This is known as the flat flux approximation. The flat flux approximation places a restriction on the mesh: if the flux varies rapidly within a region, the mesh should be refined sufficiently to ensure that the flux is well approximated by a piecewise - constant

  2. A curious fact: Photic sneeze reflex. Autosomical dominant compelling helio-ophthalmic outburst syndrome.

    2016-07-01

    To assess ocular involvement in the pathophysiology of autosomal dominant compelling helio-ophthalmic outburst syndrome (ACHOOs). An interview was conducted with a Caucasian family that showed clinical features of ACHOOs. Twelve of them had photic reflex and were recruited. A complete eye evaluation was made. A dominant autosomal inheritance with mild penetrance was demonstrated, with 67% of the studied subjects showing some degree of prominent corneal nerves. No other eye changes were found. Prominent corneal nerves may be associated with ACHOOs. The other eye structures studied do not seem to play a role in ACHOOs. Further studies are needed to understand the physiology of the ACHOOs.

    2002-01-01

    This paper presents results of simulation of void reactivity in a CANDU core using the NESTLE core simulator, cross sections from the HELIOS lattice physics code in conjunction with incremental cross sections from the DRAGON lattice physics code. First, a sub-region of a CANDU6 core is modeled using the NESTLE core simulator and predictions are contrasted with predictions by the MCNP Monte Carlo simulation code utilizing a continuous energy model. In addition, whole core modeling results are presented using the NESTLE finite difference method (FDM), NESTLE nodal method (NM) without assembly discontinuity factors (ADF), and NESTLE NM with ADF. The work presented in this paper has been performed as part of a project sponsored by the Canadian Nuclear Safety Commission (CNSC). The purpose of the project was to gather information and assess the accuracy of best estimate methods using calculational methods and codes developed independently from the CANDU industry. (author)

  6. Faraday rotation fluctutation spectra observed during solar occultation of the Helios spacecraft

    Andreev, V.; Efimov, A. I.; Samoznaev, L.; Bird, M. K.

    1995-01-01

    Faraday rotation (FR) measurements using linearly polarized radio signals from the two Helios spacecraft were carried out during the period from 1975 to 1984. This paper presents the results of a spectral analysis of the Helios S-band FR fluctuations observed at heliocentric distances from 2.6 to 15 solar radii during the superior conjunctions 1975-1983. The mean intensity of the FR fluctuations does not exceed the noise level for solar offsets greater than ca. 15 solar radii. The rms FR fluctuation amplitude increases rapidly as the radio ray path approaches the Sun, varying according to a power law (exponent: 2.85 +/- 0.15) at solar distances 4-12 solar radii. At distances inside 4 solar radii the increase is even steeper (exponent: 5.6 +/- 0.2). The equivalent two-dimensional FR fluctuation spectrum is well modeled by a single power-law over the frequency range from 5 to 50 mHz. For heliocentric distances larger than 4 solar radii the spectral index varies between 1.1 and 1.6 with a mean value of 1.4 +/- 0.2, corresponding to a 3-D spectral index p = 2.4. FR fluctuations thus display a somwhat lower spectral index compared with phase and amplitude fluctuations. Surprisingly high values of the spectral index were found for measurements inside 4 solar radii (p = 2.9 +/- 0.2). This may arise from the increasingly dominant effect of the magnetic field on radio wave propagation at small solar offsets. Finally, a quasiperiodic component, believed to be associated with Alfven waves, was discovered in some (but not all!) fluctuation spectra observed simultaneously at two ground stations. Characteristic periods and bulk velocities of this component were 240 +/- 30 sec and 300 +/- 60 km/s, respectively.

    2006-07-01

    Full Text Available This dissertation tries to make an analysis about phenomenons of violence in the region of Risaralda and your capital Pereira. The established reflection is made by means of a historical view, a violence characterization and some of your causal explanations, a reflection where the main reference is the territory and your manifold scenes that conjugate actors crossing, interests and territorial dominions, besides, a migratory process by violence (displacement by violence that materializes the sequels of conflict, and finally, by means of a local view that recognizes in the globalized societies, new non regulated scenes of conflict by the state-nation. This analysis permits to recognize the territorial topics of control and dominion and it identifies some of the structural explanations that show continuities and discontinuities that have an effect on population of the region in a differentiated way. The reflection provokes new questions to guide next investigations in the region.

  10. Comparison of thermo-hydraulic analysis with measurements for HELIOS. The scaled integral test loop for PEACER

    Cho, Jae Hyun; Lim, Jun; Kim, Ji Hak; Hwang, Il Soon

    2009-01-01

    A scaled-down Lead-Bismuth Eutectic circulating integral test loop named as HELIOS (Heavy Eutectic liquid metal Loop for Integral test of Operability and Safety of PEACER) has been employed to characterize steady-state isothermal forced circulation behavior and non-isothermal natural circulation capability of the lead and lead-alloy cooled advanced nuclear energy systems (LACANES). In this time, thermal-hydraulic experiments have been carried out using HELIOS following rigorous calibration campaigns on sensors for temperature and pressure, especially isothermal steady-state forced convection using by the pump. The isothermal steady-state forced convection test was performed to obtain the pressure loss information including friction loss coefficients and form loss coefficients. Then its data were compared with multi-approaching analysis including hand calculation results and computer simulation code results. (MARS-LBE, CFX). We report the results of comparisons between the analysis and measurements together. (author)

  11. Comparison of Serpent and HELIOS-2 as applied for the PWR few-group cross section generation

    Fridman, E.; Leppaenen, J.; Wemple, C.

    2013-01-01

    This paper discusses recent modifications to the Serpent Monte Carlo code methodology and related to the calculation of few-group diffusion coefficients and reflector discontinuity factors The new methods were assessed in the following manner. First, few-group homogenized cross sections calculated by Serpent for a reference PWR core were compared with those generated 1 commercial deterministic lattice transport code HELIOS-2. Second, Serpent and HELIOS-2 fe group cross section sets were later employed by nodal diffusion code DYN3D for the modeling the reference PWR core. Finally, the nodal diffusion results obtained using the both cross section sets were compared with the full core Serpent Monte Carlo solution. The test calculations show that Serpent can calculate the parameters required for nodal analyses similar to conventional deterministic lattice codes. (authors)

    Full Text Available La violencia y la accidentalidad son causas frecuentes de trauma en Colombia. Diferentes alternativas sobre el correcto manejo del paciente traumatizado han sido elaboradas debido a la necesidad de mejorar los protocolos para modificar de manera favorable el pronóstico de los pacientes; uno de estos ha sido la implementación de hemotransfusión masiva temprana. Se realizó un estudio con el objetivo de Identificar el número de pacientes ingresados al Hospital Universitario San Jorge de Pereira con trauma penetrante a cuello, tórax, abdomen y extremidades que cumplieron criterios para hemotransfusión masiva temprana y determinar el porcentaje de los que fueron transfundidos durante los meses de Febrero y Marzo de 2010. A partir de esto se llevó a cabo un estudio descriptivo que incluyó 64 historias clínicas de pacientes con diagnostico de trauma penetrante en las zonas anatómicas ya descritas, ingresados al Hospital universitario San Jorge de Pereira empleando un instrumento que incluía los criterios para hemotransfusión temprana y algunas variables epidemiológicas. Los resultados reflejan que el 3% de los pacientes incluidos, tenían criterios para trasfusión masiva temprana, esta no fue empleada en su protocolo de reanimación y el 97% de los pacientes estudiados no cumplía criterios de transfusión. Para determinar la utilidad de la trasfusión masiva temprana en el Hospital Universitario San Jorge, se requiere la implementación de protocolos de reanimación en los cuales se incluya los criterios de trasfusión temprana, con la finalidad de poder evaluar sobrevida en investigaciones ulteriores.

  13. HELIOS: An Open-source, GPU-accelerated Radiative Transfer Code for Self-consistent Exoplanetary Atmospheres

    We present the open-source radiative transfer code named HELIOS, which is constructed for studying exoplanetary atmospheres. In its initial version, the model atmospheres of HELIOS are one-dimensional and plane-parallel, and the equation of radiative transfer is solved in the two-stream approximation with nonisotropic scattering. A small set of the main infrared absorbers is employed, computed with the opacity calculator HELIOS-K and combined using a correlated-k approximation. The molecular abundances originate from validated analytical formulae for equilibrium chemistry. We compare HELIOS with the work of Miller-Ricci & Fortney using a model of GJ 1214b, and perform several tests, where we find: model atmospheres with single-temperature layers struggle to converge to radiative equilibrium; k-distribution tables constructed with ≳ 0.01 cm-1 resolution in the opacity function (≲ {10}3 points per wavenumber bin) may result in errors ≳ 1%-10% in the synthetic spectra; and a diffusivity factor of 2 approximates well the exact radiative transfer solution in the limit of pure absorption. We construct “null-hypothesis” models (chemical equilibrium, radiative equilibrium, and solar elemental abundances) for six hot Jupiters. We find that the dayside emission spectra of HD 189733b and WASP-43b are consistent with the null hypothesis, while the latter consistently underpredicts the observed fluxes of WASP-8b, WASP-12b, WASP-14b, and WASP-33b. We demonstrate that our results are somewhat insensitive to the choice of stellar models (blackbody, Kurucz, or PHOENIX) and metallicity, but are strongly affected by higher carbon-to-oxygen ratios. The code is publicly available as part of the Exoclimes Simulation Platform (exoclime.net).

  14. Analysis of a small PWR core with the PARCS/Helios and PARCS/Serpent code systems

    Baiocco, G.; Petruzzi, A.; Bznuni, S.; Kozlowski, T.

    2017-01-01

    Highlights: • The consistency between Helios and Serpent few-group cross sections is shown. • The PARCS model is validated against a Monte Carlo 3D model. • The fission and capture rates are compared. • The influence of the spacer grids on the axial power distribution is shown. - Abstract: Lattice physics codes are primarily used to generate cross-section data for nodal codes. In this work the methodology of homogenized constant generation was applied to a small Pressurized Water Reactor (PWR) core, using the deterministic code Helios and the Monte Carlo code Serpent. Subsequently, a 3D analysis of the PWR core was performed with the nodal diffusion code PARCS using the two-group cross section data sets generated by Helios and Serpent. Moreover, a full 3D model of the PWR core was developed using Serpent in order to obtain a reference solution. Several parameters, such as k eff , axial and radial power, fission and capture rates were compared and found to be in good agreement.

  15. HELIOS/DRAGON/NESTLE codes' simulation of the Gentilly-2 loss of class 4 power event

    2002-01-01

    A loss of electrical power occurred at Gentilly-2 in September of 1995 while the station was operating at full power. There was an unexpectedly rapid core power increase initiated by the drainage of the zone controllers and accelerated by coolant boiling. The core transient was terminated by Shutdown System No 1 (SDS1) tripping when the out-of-core ion chambers exceeded the 10%/sec high rate of power increase trip setpoint at 1.29 sec. This resulted in the station automatically shutting down within 2 sec of event initiation. In the first 2 sec, 26 of the 58 SDS1 and SDS2 in-core flux detectors reached there overpower trip (ROPT) setpoints. The peak reactor power reached approximately 110%FP. Reference 1 presented detailed results of the simulations performed with coupled thermalhydraulics and 3D neutron kinetics codes, SOPHT-G2 and the CERBERUS module of RFSP, and the various adjustments of these codes and plant representation that were needed to obtain the neutronic response observed in 1995. The purposes of this paper are to contrast a simulation prediction of the peak prompt core thermal power transient versus experimental estimate, and to note the impact of spatial discretization approach utilized on the prompt core thermal power transient and the channel power distribution as a function of time. In addition, adequacy of the time-step sizes employed and sensitivity to core's transient thermal-hydraulics conditions are studied. The work presented in this paper has been performed as part of a project sponsored by the Canadian Nuclear Safety Commission (CNSC). The purpose of the project was to gather information and assess the accuracy of best estimate methods using calculation methods and codes developed independently from the CANDU industry. The simulation of the accident was completed using the NESTLE core simulator, employing cross sections generated by the HELIOS lattice physics code, and incremental cross sections generated by the DRAGON lattice physics code

  16. Calculations of the actinide transmutation with HELIOS for fuels of light water reactors

    Francois L, J.L.; Guzman A, J.R.

    2006-01-01

    In this work a comparison of the obtained results with the HELIOS code is made and those obtained by other similar codes, used in the international community, respect to the transmutation of smaller actinides. For this the one it is analyzed the international benchmark: 'Calculations of Different Transmutation Concepts', of the Nuclear Energy Agency. In this benchmark two cell types are analyzed: one small corresponding to a PWR standard, and another big one corresponding to a PWR highly moderated. Its are considered two types of burnt of discharge: 33 GWd/tHM and 50 GWd/tHM. The following types of results are approached: the k eff like a function of the burnt one, the atomic densities of the main isotopes of the actinides, the radioactivities in the moment in that the reactor it is off and in the times of cooling from 7 up to 50000 years, the reactivity by holes and the Doppler reactivity. The results are compared with those obtained by the following institutions: FZK (Germany), JAERI (Japan), ITEP (Russia) and IPPE (Russian Federation). In the case of the eigenvalue, the obtained results with HELIOS showed a discrepancy around 3% Δk/k, which was also among other participants. For the isotopic concentrations: 241 Pu, 242 Pu and 242m Am the results of all the institutions present a discrepancy bigger every time, as the burnt one increases. Regarding the activities, the discrepancy of results is acceptable, except in the case of the 241 Pu. In the case of the Doppler coefficients the discrepancy of results is acceptable, except for the cells with high moderation; in the case of the holes coefficients, the discrepancy of results increases in agreement with the holes fraction increases, being quite high to 95% of holes. In general, the results are consistent and in good agreement with those obtained by all the participants in the benchmark. The results are inside of the established limits by the work group on Plutonium Fuels and Innovative Fuel Cycles of the Nuclear

    Full Text Available Abstract Background Non-melanoma skin cancer (NMSC is the most frequent tumour among Caucasian populations worldwide. Among the risk factors associated with this tumour, there are host-related factors and several environmental agents. A greater likelihood of high exposure to physical agents (with the exception of solar radiation and chemical agents depends on the work setting. Our objective is to evaluate the role of occupational exposures in NMSC, with special emphasis on risk factors other than solar radiation and skin type. Methods We analysed 1585 cases (1333 basal cell carcinoma (BCC and 183 squamous cell carcinoma (SCC and 1507 controls drawn from the Helios-I multicenter study. Odds ratios (OR and 95% confidence intervals (CI were estimated using logistic regression mixed models. Results For NMSC as a whole (both histological types, miners and quarrymen, secondary education teachers, and masons registered excess risk, regardless of exposure to solar radiation and skin type (OR 7.04, 95% CI 2.44–20.31; OR 1.75, 95% CI 1.05–2.89 and OR 1.54, 95% CI 1.04–2.27, respectively. Frequency of BCC proved higher among railway engine drivers and firemen (OR 4.55; 95% CI 0.96–21.57, specialised farmers (OR 1.65; 95% CI 1.05–2.59 and salesmen (OR 3.02; 95% CI 1.05–2.86, in addition to miners and quarrymen and secondary education teachers (OR 7.96; 95% CI 2.72–23.23 and OR 1.76; 95% CI 1.05–2.94 respectively. The occupations that registered a higher risk of SCC (though not of BCC were those involving direct contact with livestock, construction workers not elsewhere classified (OR 2.95, 95% CI 1.12–7.74, stationary engine and related equipment operators not elsewhere classified (OR 5.31, 95% CI 1.13–21.04 and masons (OR 2.55, 95% CI 1.36–4.78. Conclusion Exposure to hazardous air pollutants, arsenic, ionizing radiations and burns may explain a good part of the associations observed in this study. The Helios study affords an

  18. Measurement of the inertial properties of the Helios F-1 spacecraft

    Gayman, W. H.

    1975-01-01

    A gravity pendulum method of measuring lateral moments of inertia of large structures with an error of less than 1% is outlined. The method is based on the fact that in a physical pendulum with a knife-edge support the distance from the axis of rotation to the system center of gravity determines the minimal period of oscillation and is equal to the system centroidal radius of gyration. The method is applied to results of a test procedure in which the Helios F-1 spacecraft was placed in a roll fixture with crossed flexure pivots as elastic constraints and system oscillation measurements were made with each of a set of added moment-of-inertia increments. Equations of motion are derived with allowance for the effect of the finite pivot radius and an error analysis is carried out to find the criterion for maximum accuracy in determining the square of the centroidal radius of gyration. The test procedure allows all measurements to be made with the specimen in upright position.

  19. HELIOS: transformation laws for multiple-collision probabilities with angular dependence

    Villarino, E.A.; Stamm'ler, R.J.J.

    1996-01-01

    In the lattice code HELIOS, neutron and gamma transport in a given system is treated by the CCCP (current-coupling collision-probability) method. The system is partitioned into space elements which are coupled by currents. Inside the space elements first-flight probabilities are used to obtain the coefficients of the coupling equation and of the equations for the fluxes. The calculation of these coefficients is expensive in CPU time on two scores: the evaluation of the first-flight probabilities, and the matrix inversion to convert these probabilities into the desired coefficients. If the cross sections of two geometrically equal space elements, or of the same element at an earlier burnup level, differ less than a small fraction, considerable CPU time can be saved by using transformation laws. Previously, such laws were derived for first-flight probabilities; here, they are derived for the multiple-collision coefficients of the CCCP equations. They avoid not only the expensive calculations of the first-flight probabilities, but also the subsequent matrix inversion. Various examples illustrate the savings achieved by using these new transformation laws - or by directly using earlier calculated coefficients, if the cross section differences are negligible.

    2017-10-01

    A new helium line-ratio spectral monitoring (HELIOS) diagnostic, using a piezoelectric valve with high duty cycles (on/off times ms), allowing for good background correction, and measured particle flowrates on the order of 1020 particles/second is being implemented on Oak Ridge National Laboratory's (ORNL) Prototype Material Plasma Exposure eXperiment (Proto-MPEX). Built in collaboration with the University of Wisconsin - Madison, the HELIOS diagnostic communicates with a Labview program for controlled bursts of helium into the vessel. The open magnetic geometry of Proto-MPEX is ideal for testing and characterizing a HELIOS diagnostic. The circular cross-section with four ports allows for cross comparison between different diagnostics: 1) Helium injection with the piezoelectric puff valve, 2) HELIOS line-of-sight high-gain observation, 3) scan-able Double Langmuir probe, and 4) HELIOS 2D imaging observation. Electron density and temperature measurements from the various techniques will be compared. This work was supported by the US. D.O.E. contract DE-AC05-00OR22725 and DE-SC00013911.

    Full Text Available Los integrantes de los Grupos de Investigación en Comunicación Educativa y Sociedad -Imaginarios - Comunicación SIC de Colombia, han venido reflexionando, desde 1999, sobre la relación ciudad-ciudadano que se establece en los procesos de construcción de ciudad. En esta reflexión, la ciudad se ha abordado como un proceso dinámico, de lo que se deduce que es susceptible de transformaciones no sólo en el orden de lo físico, sino también de lo social, cultural, económico y político. La apuesta de este artículo, es poder visualizar la política como un proceso dinámico comunicacional en las Elecciones de Alcalde y Gobernador en el periodo electoral del año 2007 en la ciudad de Pereira (Risaralda, Colombia. En esta perspectiva, tomaremos la temporalidad como eje vinculante, de la siguiente manera: en el eje de las elecciones, distinguiremos las preselecciones, la elección y la pos-elección, donde se establecen enlaces comunicativos que permiten el funcionamiento del sistema político. Esto es lo que denominaremos modelo comunicacional, basado en la “operacionalización” de los conceptos de comunicación, acción y expectativas del sociólogo Niklas Luhmann.

  2. Generation of a library of two-group diffusion parameters for SPPS-1,6 by HELIOS

    Petkov, P.T.; Haralampieva, C.V.; Simeonov, T.; Stojanova, I.; Kamenov, K.

    2000-01-01

    The two-group three-dimensional nodal diffusion code SPPS-1.6 has been used for many years for steady-state neutronics calculations of the WWER-440 reactors at Kozloduy NPP. The old library of two-group diffusion parameters for SPPS-1.6 has been generated by WIMSD4 with a nuclear data library compiled from three different libraries. The current paper presents our experience in generating a new library for SPPS-1.6 by the HELIOS lattice code. The accuracy of the current-coupling collision probability (CCCP) method in calculating a single WWER-440 assembly has been studied first. Among all possible angular discretization of the interface partial currents, called coupling orders, only coupling order 3 is suitable for hexagonal cells. Dividing each cell side into 3 segments an accuracy of 100 pcm has been achieved. The accuracy in calculating the absorber problem was estimated at 1%, which means about 10% error in the control assemblies efficiency. The accuracy for small core-reflector problems is 1% as well. The general conclusion is that HELIOS is accurate enough for assembly calculations, but inadequate for absorber and core-reflector problems. (Authors)

  3. Time delay occultation data of the Helios spacecraft for probing the electron density distribution in the solar corona

    1978-01-01

    S-band time delay measurements were collected from the spacecraft Helios A and B during three solar occultations in 1975/76 within heliocentric distances of about 3 and 215 earth radius in terms of range, Doppler frequency shift, and electron content. Characteristic features of measurement and data processing are described. Typical data sets are discussed to probe the electron density distribution near the sun (west and east limb as well) including the outer and extended corona. Steady-state and dynamical aspects of the solar corona are presented and compared with earth-bound-K-coronagraph measurements. Using a weighted least squares estimation, parameters of an average coronal electron density profile are derived in a preliminary analysis to yield electron densities at r = 3, 65, 215 earth radius. Transient phenomena are discussed and a velocity of propagation v is nearly equal to 900 km/s is determined for plasma ejecta from a solar flare observed during an extraordinary set of Helios B electron content measurements.

  4. Technical Findings, Lessons Learned, and Recommendations Resulting from the Helios Prototype Vehicle Mishap

    Noll, Thomas E.; Ishmael, Stephen D.; Henwood, Bart; Perez-Davis, Marla E.; Tiffany, Geary C.; Madura, John; Gaier, Matthew; Brown, John M.; Wierzbanowski, Ted

    The Helios Prototype was originally planned to be two separate vehicles, but because of resource limitations only one vehicle was developed to demonstrate two missions. The vehicle consisted of two configurations, one for each mission. One configuration, designated HP01, was designed to operate at extremely high altitudes using batteries and high-efficiency solar cells spread across the upper surface of its 247-foot wingspan. On August 13, 2001, the HP01 configuration reached an altitude of 96,863 feet, a world record for sustained horizontal flight by a winged aircraft. The other configuration, designated HP03, was designed for long-duration flight. The plan was to use the solar cells to power the vehicle's electric motors and subsystems during the day and to use a modified commercial hydrogen-air fuel cell system for use during the night. The aircraft design used wing dihedral, engine power, elevator control surfaces, and a stability augmentation and control system to provide aerodynamic stability and control. At about 30 minutes into the second flight of HP03, the aircraft encountered a disturbance in the way of turbulence and morphed into an unexpected, persistent, high dihedral configuration. As a result of the persistent high dihedral, the aircraft became unstable in a very divergent pitch mode in which the airspeed excursions from the nominal flight speed about doubled every cycle of the oscillation. The aircraft s design airspeed was subsequently exceeded and the resulting high dynamic pressures caused the wing leading edge secondary structure on the outer wing panels to fail and the solar cells and skin on the upper surface of the wing to rip away. As a result, the vehicle lost its ability to maintain lift, fell into the Pacific Ocean within the confines of the U.S. Navy's Pacific Missile Range Facility, and was destroyed. This paper describes the mishap and its causes, and presents the technical recommendations and lessons learned for improving the design

  6. Foxp3+ Treg expanded from patients with established diabetes reduce Helios expression while retaining normal function compared to healthy individuals.

    Weiting Du

    Full Text Available Foxp3(+ regulatory T cells (Treg play a crucial role in regulating immune tolerance. The use of Treg to restore immune tolerance is considered an attractive novel approach to inhibit autoimmune disease, including type 1 diabetes (T1D, and to prevent rejection of organ transplants. In view of the goal of developing autologous Treg-based cell therapy for patients with long-term (>15 years T1D, it will be necessary to expand a sufficient amount of functional Treg in vitro in order to study and compare Treg from T1D patients and healthy subjects. Our results have demonstrated that there is a comparable frequency of Treg in the peripheral blood lymphocytes (PBLs of patients with long-term T1D relative to those in healthy subjects; however, Th1 cells, but not Th17 cells, were increased in the T1D patients. Further, more Treg in PBLs from T1D patients than from healthy subjects expressed the CD45RO(+ memory cell phenotype, suggesting they were antigen-experienced cells. After isolation, Treg from both T1D patients and healthy subjects were successfully expanded with high purity. Although there was no difference in Helios expression on Treg in PBLs, in vitro expansion led to fewer Helios-expressing Treg from T1D patients than healthy subjects. While more Th1-like Treg expressing IFN-γ or TNF-α were found in the PBLs of T1D patients than healthy controls, there was no such difference in the expanded Treg. Importantly, expanded Treg from both subject groups were able to suppress autologous or allogeneic CD8(+ effector T cells equally well. Our findings demonstrate that a large number of ex vivo expanded functional Treg can be obtained from long-term T1D patients, although fewer expanded Treg expressed a high level of Helios. Thus, based on the positive outcomes, these potent expanded Treg from diabetic human patients may be useful in treating T1D or preventing islet graft rejection.

  14. Magnetic fields and flows between 1 and 0.3 AU during the primary mission of Helios 1

    1978-01-01

    Helios 1 moved from 1 AU on December 10, 1974, to 0.31 AU on March 15, 1975, and the sun rotated beneath the spacecraft nearly 4 times during the interval. Recurrent high-speed streams with uniform magnetic polarity were observed, and they were associated with coronal holes of the same polarity. Although they were recurrent, the streams and their magnetic field patterns were not stationary, because the coronal holes which produced them changed in shape and latitude from one rotation to the next. We estimated that the magnetic field intensity of open field lines in some of these holes was of the order 10--20 G. Recurrent slow flows were also observed. The magnetic field polarity and intensity in these flows were irregular, and they changed from one rotation to the next. Cold magnetic enhancements (CME's) characterized by a twofold to threefold enhancement of magnetic field intensity and a fivefold to sevenfold depression of proton temperature relative to conditions ahead of the CME's were observed in some slow flows. Some of these CME's were contiguous with interaction regions of streams. At perihelion, Helios observed a recurrent stream which was associated with a lobe of the south polar coronal hole. The longitudinal width of the stream was three times that of the hole. We estimate that the width of the eastern and western boundaries of the streams at the coronal holes was only 2.5 0 +- 1.5 0 , and we infer that the width at the northern boundary of the stream was 0 . We conclude that between the sun and 0.3 AU there was a diverging stream surrounded by a thin boundary layer in which there was a large velocity shear. There is evidence for compression of the magnetic field in the western boundary layer (interaction region), presumably due to steepening of the stream within 0.31 AU

    Full Text Available O objetivo deste artigo é analisar como a trajetória da Ação Popular (AP, organização de esquerda das décadas de 1960 e 1970, é narrada e interpretada por Duarte Pacheco Pereira, um dos mais importantes dirigentes de sua história. Caracterizada por sua origem heterodoxa, influenciada pelo humanismo cristão, pelo existencialismo e pelo marxismo, a AP estabeleceu, na conjuntura posterior a 1964, um processo de ruptura com seu passado e de adesão à tradição do marxismo-leninismo, que foi permeado por tensões e cisões políticas. Investigando a interface entre as suas memórias e a história da AP, procura-se aferir sua contribuição à interpretação da singular práxis dessa organização política. A análise tem o suporte de entrevistas concedidas por Duarte Pacheco Pereira, de uma palestra que ele proferiu e do fundo documental que leva seu nome, disponível no Arquivo Edgard Leuenroth.

    2013-09-01

    HELIOS1A End Of Live (EOL) operations occurred in the early 2012. Through this EOL operation, CNES wanted to make an example of French Space Act compliance. Because the satellite wasn't natively designed for such an EOL phase, the operation was touchy and risky. It was organized as a real full project in order to assess every scenario details with dedicated Mission Analysis, to secure the operations through detailed risk analysis at system level and to consider the major failures that could occur during the EOL. A short scenario allowing to reach several objectives with benefits was eventually selected. The main objective of this project was to preserve space environment. The operations were led on a "best effort" basis. The French Space Operations Act (FSOA) requirements were met: HELIOS-1A EOL operations had been led successfully.

    Full Text Available RESUMO O objetivo deste trabalho foi verificar a influência de diferentes espaçamentos de plantio sobre o crescimento vegetativo de pereiras das cvs. Rocha e Hosui, em sistema orgânico de produção. As mudas das pereiras ‘Rocha’ e ‘Hosui’ enxertadas sobre o marmeleiro ‘CP’ foram plantadas em setembro de 2009. Os espaçamentos utilizados foram: 1,0; 0,8; 0,6 e 0,4 m, entre plantas por 3,5 m entre linhas, equivalendo às densidades de plantio de 2.857; 3.571; 4.762 e 7.143 plantas ha-1, respectivamente. Por dois ciclos consecutivos - 2011/2012 e 2012/2013 -, referentes ao terceiro e ao quarto anos após o plantio, respectivamente, foram avaliadas as variáveis diâmetro detronco, diâmetro de ramos e número de ramos. No segundo ciclo, foram avaliados o volume de copa, a área foliar estimada, a cobertura do dossel e os teores de clorofila a, b e total. Considerando as variáveis: projeção vertical de área foliar estimada, volume de copa e diâmetro de tronco e ramos, para a cv. Hosui, observou-se maior vigor vegetativo em relação à cv. Rocha. A cv. Rocha apresentou redução dos teores de clorofila no menor espaçamento entre plantas, enquanto na cv. Hosui os teores de clorofila não variaram com o espaçamento. Ocorreu aumento da área foliar estimada em função do adensamento para as duas cultivares; para o volume de copa, porém, este efeito foi observado apenas para a cv. Hosui, e para o índice de cobertura de dossel, apenas para a cv. Rocha. O maior adensamento de plantio favoreceu as pereiras da cv. Hosui, proporcionando maior volume de copa por área de terreno, sem ocorrer redução dos teores foliares de clorofila, mas com aumento da cobertura do dossel. Para a cv. Rocha, no entanto, adensamentos maiores do que 4.700 plantas ha-1 parecem ser prejudiciais, visto promoverem redução dos teores foliares de clorofila, porém com maior cobertura do dossel, podendo indicar autossombreamento.

    The reactivity and power distribution errors of the HELIOS/MASTER core calculation under power generating conditions are assessed using a whole core transport code DeCART. For this work, the cross section tablesets were generated for a medium sized PWR following the standard procedure and two group nodal core calculations were performed. The test cases include the HELIOS calculations for 2-D assemblies at constant thermal conditions, MASTER 3D assembly calculations at power generating conditions, and the core calculations at HZP, HFP, and an abnormal power conditions. In all these cases, the results of the DeCART code in which pinwise thermal feedback effects are incorporated are used as the reference. The core reactivity, assemblywise power distribution, axial power distribution, peaking factor, and thermal feedback effects are then compared. The comparison shows that the error of the HELIOS/MASTER system in the core reactivity, assembly wise power distribution, pin peaking factor are only 100∼300 pcm, 3%, and 2%, respectively. As far as the detailed pinwise power distribution is concerned, however, errors greater than 15% are observed

  7. "El sol no siempre brilla para todos": estrategias de inserción de los jóvenes afrocolombianos a la ciudad de Pereira

    Sandra Patricia Martínez Basallo

    Full Text Available The accelerated urbanization process of the Afro-Colombian population can be explained from the growing migratory flow from the Pacific region toward the cities; among which, Pereira has acquired relative importance in recent years as a pole of attraction for this population. Nevertheless, the migratory phenomenon toward this city, as well as integration processes of migrants onto the receptor society have received little attention from social analysts. In this sense, this paper seeks to contribute to clarifying the urban insertion strategies deployed by Afro-Colombian migrants, highlighting the specific experience of young men and women coming from the department of Chocó, because they constitute one of the population groups that are most strongly impacted by said phenomenon. In light of this case study, we intend to show that, by virtue of their ethnic-racial heritage, regional origin, and social class, these young people encounter adverse conditions in their integration process onto urban life

    Gubler, Hanspeter; Clare, Nicholas; Galafassi, Laurent; Geissler, Uwe; Girod, Michel; Herr, Guy

    2018-06-01

    We describe the main characteristics of the Novartis Helios data analysis software system (Novartis, Basel, Switzerland) for plate-based screening and profiling assays, which was designed and built about 11 years ago. It has been in productive use for more than 10 years and is one of the important standard software applications running for a large user community at all Novartis Institutes for BioMedical Research sites globally. A high degree of automation is reached by embedding the data analysis capabilities into a software ecosystem that deals with the management of samples, plates, and result data files, including automated data loading. The application provides a series of analytical procedures, ranging from very simple to advanced, which can easily be assembled by users in very flexible ways. This also includes the automatic derivation of a large set of quality control (QC) characteristics at every step. Any of the raw, intermediate, and final results and QC-relevant quantities can be easily explored through linked visualizations. Links to global assay metadata management, data warehouses, and an electronic lab notebook system are in place. Automated transfer of relevant data to data warehouses and electronic lab notebook systems are also implemented.

  11. Optimization of angular setup with proposed β–η chart for solar energy apparatus through Helios orbital analysis

    Ou, Chung-Jen

    2014-01-01

    Highlights: • Analysis procedure for the angular setup of the SPVS based on Helios orbital analysis is shown. • Average of 61.87% efficiency for the whole year with this fixed-type SPVS is obtained. • Graphical interpretation on proposed β–η chart for estimating SPVS efficiency is presented. - Abstract: Many reports and patents address tracking-type systems to complete and optimized the acquisition of solar energy. However, fixed-type systems contribute the most of the market to the solar photovoltaic system (SPVS) for the existing buildings. Based on this fact, it is important to discuss and understand the feasible setup parameters to achieve the optimum radiation-collection-efficiency of a fixed-type system. The purpose of the present report is to provide the methodology and to investigate the optimum angles of the system facilities through minimum mathematics. The calculations show that for the demonstrated locations, the maximum efficiency for the whole year of a fixed-type system can reach more than 61% efficiency, compared to a total tracking system at the same location and time intervals. Based on these calculations, the appropriate optical system can be designed to improve system performance for the majority buildings requirements in any location

  12. Measurement of low mass muon pairs in sulphur-nucleus collisions with an optimized HELIOS muon spectrometer

    2002-01-01

    Dileptons provide a unique and specific tool to detect collective behaviour and to probe for signs of quark gluon plasma formation in nucleus-nucleus interactions. In particular, in the low transverse mass region, below the rho meson, dimuons probe the thermal nature of the interaction while their multiplicity dependence can indicate nuclear volume effects. \\\\\\\\This experiment uses the (almost) unchanged HELIOS muon spectrometer and a combination of a new carefully designed light absorber, at an optimized distance from the target, and multiplicity measurements provided by new Silicon ring detectors, covering more than the muon rapidity acceptance. It intends to improve in quality and quantity on the low mass, low $p_{T}$ dimuon signal already observed in the NA34/2 experiment. The wide range of rapidity from 3.5 to 6.0 will enable us to explore the rapidity dependence of the signal from high energy density at nearly central rapidity up to very forward rapidities. \\\\\\\\The commissioning of the new apparatus (...

  13. Helios: a Multi-Purpose LIDAR Simulation Framework for Research, Planning and Training of Laser Scanning Operations with Airborne, Ground-Based Mobile and Stationary Platforms

    Bechtold, S.; Höfle, B.

    2016-06-01

    In many technical domains of modern society, there is a growing demand for fast, precise and automatic acquisition of digital 3D models of a wide variety of physical objects and environments. Laser scanning is a popular and widely used technology to cover this demand, but it is also expensive and complex to use to its full potential. However, there might exist scenarios where the operation of a real laser scanner could be replaced by a computer simulation, in order to save time and costs. This includes scenarios like teaching and training of laser scanning, development of new scanner hardware and scanning methods, or generation of artificial scan data sets to support the development of point cloud processing and analysis algorithms. To test the feasibility of this idea, we have developed a highly flexible laser scanning simulation framework named Heidelberg LiDAR Operations Simulator (HELIOS). HELIOS is implemented as a Java library and split up into a core component and multiple extension modules. Extensible Markup Language (XML) is used to define scanner, platform and scene models and to configure the behaviour of modules. Modules were developed and implemented for (1) loading of simulation assets and configuration (i.e. 3D scene models, scanner definitions, survey descriptions etc.), (2) playback of XML survey descriptions, (3) TLS survey planning (i.e. automatic computation of recommended scanning positions) and (4) interactive real-time 3D visualization of simulated surveys. As a proof of concept, we show the results of two experiments: First, a survey planning test in a scene that was specifically created to evaluate the quality of the survey planning algorithm. Second, a simulated TLS scan of a crop field in a precision farming scenario. The results show that HELIOS fulfills its design goals.

  14. Helios expression and Foxp3 TSDR methylation of IFNy+ and IFNy- Treg from kidney transplant recipients with good long-term graft function.

    Karina Trojan

    Full Text Available There is circumstantial evidence that IFNy+ Treg might have clinical relevance in transplantation. IFNy+ Treg express IFNy receptors and are induced by IFNy. In the present study we investigated in kidney transplant recipients with good long-term stable graft function the absolute cell counts of IFNy+ Treg subsets and whether their expression of Foxp3 is stable or transient.Helios expression determined by eight-color-fluorescence flow cytometry and methylation status of the Foxp3 Treg specific demethylation region (TSDR served as indicators for stability of Foxp3 expression. Methylation status was investigated in enriched IFNy+ and IFNy- Treg preparations originating from peripheral blood using high resolution melt analysis. A total of 136 transplant recipients and 52 healthy controls were studied.Proportions of IFNy+ Treg were similar in patients and healthy controls (0.05% and 0.04% of all CD4+ lymphocytes; p = n.s.. Patients also had similar absolute counts of IFNy producing Helios+ and Helios- Treg (p = n.s.. Most of the IFNy+ and IFNy- Treg in transplant recipients had a methylated Foxp3 TSDR, however, there was a sizeable proportion of IFNy+ and IFNy- Treg with demethylated Foxp3 TSDR. Male and female patients showed more frequently methylated IFNy+ and IFNy- Treg than male and female controls (all p<0.05.Kidney transplant recipients with good long-term stable graft function have similar levels of IFNy+ Treg as healthy controls. IFNy+ and IFNy- Treg subsets in patients consist of cells with stable and cells with transient Foxp3 expression; however, patients showed more frequently methylated IFNy+ and IFNy- Treg than controls. The data show increased levels of Treg subsets with stable as well as transient Foxp3 expression in patients with stable allograft acceptance compared to healthy controls.

    2015-01-01

    Full Text Available Este texto es elaborado en el marco de un proyecto de investigación del grupo "Educación y Desarrollo Humano", con el objetivo de analizar la forma en que se teje la dimensión social del género en el ámbito de la Universidad Tecnológica de Pereira, como elemento que participa de manera fundamental en las relaciones de poder. La movilización de las mujeres en las décadas iniciales del siglo XX por el derecho a acceder a la educación superior y la creación de la Universidad Tecnológica de Pereira en 1958 facilitaron el ingreso de las mujeres de la región del "Gran Caldas" a la universidad. La experiencia pionera se realiza en el campo de la ingeniería, contrastando con tendencias observadas en otras universidades del país. Posteriormente, con la apertura de nuevos programas se diversifican las áreas de su profesionalización, en el lapso transcurrido desde los años setenta hasta el período finisecular. La feminización de la matrícula y de las áreas de conocimiento en las cuales se participa como estudiante reproduce patrones culturales y sociales tradicionales con relación a la formación de las mujeres. Estos modelos se replican en el campo docente y administrativo de la universidad, en lo que se refiere a la dimensión de equidad de género entre los docentes universitarios. Basándose en la experiencia interdisciplinaria sobre la construcción del pensamiento femenino que desde los años setenta irrumpe en esta universidad, se realiza un análisis exploratorio sobre la travesía de este objeto de estudio en el contexto académico y sobre la relación tejida entre la academia y el movimiento social de mujeres en la región.

    Full Text Available Una investigación fenomenológica, adelantada desde la perspectiva latinoamericana de los Estudios Culturales en Pereira y Dosquebradas, en el Departamento de Risaralda, Colombia, tendiente a comprender la relación entre mediaciones tecnológicas y procesos de subjetivación juvenil, permitió identificar que estos procesos adoptan hoy una forma que hemos denominado «subjetivaciones tecnojuveniles», categoría ésta que refiere la interdependencia existente entre ambos fenómenos, es decir, la necesidad que experimentan los jóvenes de interactuar cotidianamente con las tecnologías, pero, así mismo, la necesidad que experimentan los mediadores que están detrás del fenómeno respecto al aporte de los jóvenes para la transformación permanente de tales discursos y prácticas no discursivas (de poder. Estos procesos de subjetivación se están transformando a un ritmo vertiginoso y están produciendo formas emergentes de dialogicidad y de estilos de vida juvenil, caracterizados, entre otros rasgos, por una sensación de poder sobre el propio trayecto vital, expresado, entre otras manifestaciones, por expectativas favorables sobre sí mismos, su presente y su futuro.

  20. Na sombra de Herculano: Miguel Ângelo Pereira e os desafios de compor ópera no Portugal dos anos 1860-70

    Cymbron, Luísa

    2014-04-01

    Full Text Available In February 1870 an opera based on the novel Eurico by Alexandre Herculano was premiered at the Teatro S. Carlos in Lisbon. The composer, Miguel Ângelo Pereira (1843-1901, was a young pianist and composer, born in the North of Portugal, who had spent part of his childhood and adolescence in Brazil. Even though it was not well received by the public and the critics, the opera was revived in 1874 in Oporto and in 1878 in Rio de Janeiro. From the start Eurico was portrayed as a different work from the current repertory, and was sometimes associated with the world of German instrumental music. Based on the few surviving sources and the contemporary press, this article attempts to show how Eurico fits in to the projects seeking to create a Portuguese national opera that were undertaken by a group of emigrants in Rio de Janeiro; how, in dramaturgical and musical terms, it is also close to the aesthetics of grand opéra; and how the psychological profile of the Miguel Ângelo – who thought of himself and is also described by his contemporaries, as a hero in search of an ideal –, allied to the emergence of a new musical canon, based on the works of the German composers, led to it being considered, after the death of its author in 1901, as the first attempt by a Portuguese composer to approach Wagnerian models.En febrero de 1870 se estrenó en el Teatro de S.

  4. Solar-wind predictions for the Parker Solar Probe orbit. Near-Sun extrapolations derived from an empirical solar-wind model based on Helios and OMNI observations

    Venzmer, M. S.; Bothmer, V.

    2018-03-01

    Context. The Parker Solar Probe (PSP; formerly Solar Probe Plus) mission will be humanitys first in situ exploration of the solar corona with closest perihelia at 9.86 solar radii (R⊙) distance to the Sun. It will help answer hitherto unresolved questions on the heating of the solar corona and the source and acceleration of the solar wind and solar energetic particles. The scope of this study is to model the solar-wind environment for PSPs unprecedented distances in its prime mission phase during the years 2018 to 2025. The study is performed within the Coronagraphic German And US SolarProbePlus Survey (CGAUSS) which is the German contribution to the PSP mission as part of the Wide-field Imager for Solar PRobe. Aim. We present an empirical solar-wind model for the inner heliosphere which is derived from OMNI and Helios data. The German-US space probes Helios 1 and Helios 2 flew in the 1970s and observed solar wind in the ecliptic within heliocentric distances of 0.29 au to 0.98 au. The OMNI database consists of multi-spacecraft intercalibrated in situ data obtained near 1 au over more than five solar cycles. The international sunspot number (SSN) and its predictions are used to derive dependencies of the major solar-wind parameters on solar activity and to forecast their properties for the PSP mission. Methods: The frequency distributions for the solar-wind key parameters, magnetic field strength, proton velocity, density, and temperature, are represented by lognormal functions. In addition, we consider the velocity distributions bi-componental shape, consisting of a slower and a faster part. Functional relations to solar activity are compiled with use of the OMNI data by correlating and fitting the frequency distributions with the SSN. Further, based on the combined data set from both Helios probes, the parameters frequency distributions are fitted with respect to solar distance to obtain power law dependencies. Thus an empirical solar-wind model for the inner

    Full Text Available http://dx.doi.org/10.5007/2175-7925.2015v28n2p73 A existência de polinizadores capazes de promover a xenogamia é um fator decisivo na produtividade dos pomares. Por ser alógama, devido à autoincompatibilidade gametofítica, a maioria das cultivares europeias de pereiras não produzem frutos com sementes sem a presença de insetos polinizadores. Portanto, o correto manejo e a qualidade das colmeias de Apis mellifera instaladas nos pomares são imprescindíveis para assegurar produções economicamente viáveis. Nesse contexto, objetivou-se avaliar alguns aspectos do sistema de polinização dirigida com A. mellifera que podem interferir decisivamente na eficiência da polinização em um pomar comercial de pereira portuguesa nas condições ecológicas do planalto serrano catarinense, no Sul do Brasil. Foi observada uma baixa visitação de abelhas nas flores de pereira, possivelmente devido a dois fatores: competição floral e densidade insuficiente de colmeias instaladas no pomar. Não foi observada a deposição de pólen nos estigmas, o que confirma a deficiência de polinização na área. A qualidade das colmeias alugadas apresentou diferenças entre os anos, com presença do ácaro Varroa destructor e do microsporídeo Nosema ceranae, os quais podem ter contribuído para o despovoamento das colmeias durante o período de floração e, consequentemente, redução da deposição de pólen no estigma das flores da cultivar produtora de frutos.

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

No ano agrícola de 2005, na Fazenda Bonança, no município de Pereira Barreto, Estado de São Paulo, Brasil, foram analisadas a produtividade de forragem do milho outonal (MSF no sistema plantio direto irrigado, a porosidade total (PT e a densidade do solo (DS em profundidade, em um Latossolo Vermelho distrófico. O objetivo foi estudar a variabilidade e as correlações lineares e espaciais entre os atributos da planta e do solo, visando selecionar um indicador da qualidade física do solo de boa representatividade para produtividade da forragem. Foi instalada a malha geoestatística, para coleta de dados do solo e planta, contendo 125 pontos amostrais, numa área de 2.500 m². Os atributos estudados, além de não terem variado aleatoriamente, apresentaram variabilidade dos dados entre média e baixa e seguiram padrões espaciais bem definidos, com alcance entre 6,8 e 23,7 m. Por sua vez, a correlação linear entre o atributo da planta e os do solo, em razão do elevado número de observações, foi baixa. As observações de melhor correlação com a MSF foram a DS1 e a PT1. Entretanto, do ponto de vista espacial, houve excelente correlação inversa entre a MSF e a DS1, assim como entre a DS1 e a PT1. Nos sítios onde a DS1 aumentou (1,45-1,64 kg dm-3 a MSF variou entre 11.653 e 14.552 kg ha-1; já naqueles onde diminuiu (1,35-1,45 kg dm-3 a MSF, ficou entre 14.552 e 17.450 kg ha-1. Portanto, a densidade global, avaliada na camada de 0-0,10 m (DS1, apresentou-se como satisfatório indicador da qualidade física do solo de Pereira Barreto (SP, quando destinado à produtividade de forragem do milho outonal.Total porosity and bulk density are strongly affected by soil management, which is reflects directly in agricultural productivity.

Our hypothesis is that, in order to use Gilberto Freyre’s ideas, these intellectuals chose the image of the Brazilian people as a racially, ethnically and culturally heterogeneous people, but in the process of integration. This is not to say that they only reproduce these ideas, but actively used in shaping the habitus of cinematographic field at that time.

    Full Text Available The HelioClim-3 database (HC3v3 provides records of surface solar irradiation every 15 min, estimated by processing images from the geostationary meteorological Meteosat satellites using climatological data sets of the atmospheric Linke turbidity factor. This technical note proposes a method to improve a posteriori HC3v3 by combining it with data records of the irradiation under clear skies from the new McClear clear-sky model, whose inputs are the advanced global aerosol property forecasts and physically consistent total column content in water vapour and ozone produced by the MACC (Monitoring Atmosphere Composition and Climate projects. The method is validated by comparison with a series of ground measurements for 15 min and 1 h for 6 stations and for daily irradiation for 23 stations. The correlation coefficient is large, greater than respectively 0.92, 0.94, and 0.97, for 15 min, 1 h and daily irradiation. The bias ranges from −4 to 4% of the mean observed irradiation for most sites. The relative root mean square difference (RMSD varies between 14 and 38% for 15 min, 12 and 33% for 1 h irradiation, and 6 and 20% for daily irradiation. As a rule of thumb, the farther from the nadir of the Meteosat satellite located at latitude 0° and longitude 0°, and the greater the occurrence of fragmented cloud cover, the greater the relative RMSD. The method improves HC3v3 in most cases, and with no degradation in the others. A systematic correction of HC3v3 with McClear is recommended.

    Little is known about a possible interaction of natural killer (NK) cells with regulatory T cells (T reg ) in long-term stable kidney transplant recipients. Absolute counts of lymphocyte and T reg subsets were studied in whole blood samples of 136 long-term stable renal transplant recipients and 52 healthy controls using eight-colour fluorescence flow cytometry. Patients were 1946 ± 2201 days (153-10 268 days) post-transplant and showed a serum creatinine of 1·7 ± 0·7 mg/dl. Renal transplant recipients investigated > 1·5 years post-transplant showed higher total NK cell counts than recipients studied express the phenotype Helios + interferon (IFN)-γ - and appear to have stable FoxP3 expression and originate from the thymus. Furthermore, high total NK cells were associated with T reg that co-express the phenotypes interleukin (IL)-10 - transforming growth factor (TGF)-β + (P = 0·013), CD183 + CD62L - (P = 0·003), CD183 + CD62 + (P = 0·001), CD183 - CD62L + (P = 0·002), CD252 - CD152 + (P term good allograft function and the statistical association of these two lymphocyte subsets with each other suggest a direct or indirect (via DC) interaction of these cell subpopulations that contributes to good long-term allograft acceptance. Moreover, we speculate that regulatory NK cells are formed late post-transplant that are able to inhibit graft-reactive effector cells. © 2017 British Society for Immunology.

    Full Text Available Biological control by using epiphytic bacteria against Erwinia amylovora has been considered as an alternative method for controlling the disease. Talc-based formulation of Pantoea agglomerans strain Eh-24 was applied at 30% and 100% bloom on two pear orchards which were selected from different locations in the Aegean Region in Turkey. Pear orchard trials were replicated for two years (1999 and 2000 in each place. Talc-based formulation of P. agglomerans strain Eh-24 was sprayed on pear trees which were naturally infected with E. amylovora. In the orchard trials conducted in 1999 and 2000, talc-based formulation of P. agglomerans strain Eh-24 reduced the percentage of blighted blossoms on pear orchards by 63% to 76%, approximately. Copper oxychloride+maneb was less effective in reducing the incidence of blossom infection by E. amylovora in each pear orchard than the bioformulation treatment. P. agglomerans strain Eh-24 labelled with StrR+ was applied at 30% and 100% bloom to monitor the colonization and population dynamics of P. agglomerans on pear blossoms. The population size of P. agglomerans strain Eh-24 strR+ on pear blossoms increased from 2x10(4 to 1.3x10(6 cfu per blossom over 18 days.Controle biológico de Erwinia amylovora através do uso de bactérias epifíticas tem sido considerado um método alternativo para o controle de "fire blight". Uma formulação de Pantoea agglomerans Eh 24 em talco foi utilizada em pereiras a 30% e a 100% de floração, em duas plantações selecionadas na região Aegean da Turquia. Os experimentos foram repetidos duas vezes (1999 e 2000 em cada plantação. A formulação de P. agglomerans foi aspergida nas pereiras naturalmente infectadas com E. amylovora. Nos experimentos de 1999 e 2000, a redução da porcentagem de ocorrência de "fire blight" foi reduzida aproximadamente em 63% e em 76%, respectivamente. Oxicloreto de cobre + maneb foi menos eficiente na redução da infecção por E. amylovora do

    Full Text Available Em revisão de 1991, a American Thoracic Society (ATS recomenda que cada região defina equações próprias para obtenção dos valores teóricos (VTs dos parâmetros espirométricos, que traduzam a realidade funcional para a população local. Quando dessa recomendação, os EUA já dispunham de diversos sistemas de equações próprios, bem como a Comunidade Européia e a Polônia em particular. Em 1992, Pereira et al., analisando 4.200 espirogramas de brasileiros normais, encontraram VT para capacidade vital forçada (CVF, volume expiratório forçado de 1 seg. (VEF1 e de fluxo expiratório médio (FEF25-75 diferentes dos descritos pelos autores americanos e europeus. Este estudo foi realizado para comparar as equações de Pereira et al., desenvolvida a partir de amostra de população brasileira, e as americanas de Knudson et al., bastante utilizadas em nosso meio. Foi também investigada a conseqüente influência nos laudos espirométricos, quando uma ou outra é empregada. Foram analisados 1.070 espirogramas de pacientes de ambos os sexos (389 homens e 681 mulheres que vieram ao serviço para avaliação funcional de rotina. Não foi excluída qualquer patologia nem levada em conta a situação tabágica do paciente. Para cada paciente foi feito o cálculo do VT para CVF, VEF1 e FEF25-75 segundo as equações de Pereira (VT-P e de Knudson 1983 (VT-K e comparados as médias, desvios padrões e os laudos obtidos por um e por outro. Os VT-K para a CVF foram de 4,01% [p < 0,005] maiores entre as mulheres, levando a sobrevalorização das restrições respiratórias, mas entre os homens não houve diferença relevante. Quanto à VEF1, os VT-P foram superiores tanto em homens (4,76% [p < 0,005] como em mulheres (5,04% [p < 0,05], levando a maior sensibilidade na identificação de obstruções respiratórias. Não se observou diferença relevante entre os VT-P e VT-K para o FEF25-75 em nenhum dos sexos.

    Full Text Available A adubação de plantas frutíferas de clima temperado é rotineiramente recomendada em função da interpretação de laudos de análises químicas de solo e folhas, mas não são específicas para as diferentes cultivares e porta-enxertos. Neste contexto, um experimento foi conduzido durante dois anos, com o objetivo de avaliar o estado nutricional de diferentes cultivares de pereira enxertadas sobre o porta-enxerto marmeleiro 'CP', em Guarapuava-PR. As cultivares de pereira Cascatense, Tenra, Hosui, Packham's Triumph e Williams foram plantadas em 2004, em densidade de 2.500 plantas ha-1. Amostras de folhas e de frutos foram coletadas em 2006 e 2007 para análises químicas dos teores de nutrientes. Folhas completas e normais foram amostradas em meados de janeiro, retiradas da parte mediana das brotações do ano. Os frutos foram colhidos quando o teor de sólidos solúveis totais atingiram 10º Brix. As cultivares de pereira apresentaram diferenças em relação aos teores de nutrientes nas folhas e frutos, demonstrando exigências nutricionais distintas. A cv. Cascatense apresentou os maiores teores de N e P nos frutos em, pelo menos, um dos anos avaliados, e a cv. Hosui, os maiores valores para K. A extração de nutrientes pelos frutos situou-se entre 0,366 e 0,825 kg de N; 0,097 e 0,205 kg de P; 0,996 e 1,302 kg de K; 0,085 e 0,049 a 0,085 kg de Ca, e entre 0,041 e 0,095 kg de Mg por tonelada de frutos.The fertilizer applications in deciduous fruit trees are usually recommended in function of chemical soil and leaves analysis interpretation, but they are not specific for the different scion and rootstock cultivars. In this context, a trial was carried out aiming to evaluate the nutritional status of different pear cultivars grafted on rootstock quince 'CP' by two consecutive years, in Guarapuava, Paraná State, Brazil. The pear cultivars Cascatense, Tenra, Hosui, Packham's Triumph and Williams were planted in 2004 at the density planting

    To ensure safe oral administration, pediatric patients require an appropriate dosage form to be swallowed without relevant difficulties. Ex tempore hydrated powders, forming viscous pulp "on a spoon", have recently gained much interest as pediatric formulations. The aim of this study was to evaluate the viscosity-increasing substances and disintegrants, alone or in mixtures, as excipients suitable for preparing such formulations, with candesartan and valsartan chosen as model active substances. The mixtures of excipients were prepared in the form of powders, granules or lyophilizates, which were evaluated in terms of their ability to form a homogenous mass after hydration with a small amount of water. The best compositions were tested with candesartan cilexetil and valsartan (2% and 10% w/w, respectively). Performed studies include macroscopic, organoleptic and microscopic observations, as well as a textural analysis, determination of gelation time and rheological measurements. Mixtures of guar gum, lactose and one of the disintegrants (F-Melt M, Prosolv 50, Prosolv Easy, Lycatab, Pharmaburst, Pearlitol) demonstrated the best properties. With regard to drug-incorporating formulations, granules were evaluated as the most satisfying form, while the functional properties of lyophilized formulations were poor. Granules with candesartan cilexetil (2%) were found to be the most promising for further development.

    Johansson, Sverker.

    1990-05-01

    The main part of this thesis treats measurements in the HELIOS experiment of the production of eμ and μμ-pairs in 450 GeV/c p-Be collisions. The μμ measurement covers the kinematical range of 2Mμ F + μ - is for the first time experimentally measured. The continuum at masses below Μρ is studied, and compared with the contributions from known sources, normalized to the vector-meson peaks in the μμ mass spectrum, and to measurements in this experiment of the η cross section. The result is compared with that of other experiments, discussed in terms of the different background estimates used. A significant signal of unlike-sign eμ pairs is observed, forming a continuum peaking at a mass below 500 MeV. Correlations between eμ and neutrino production are studied. The shape of the eμ-mass and Ευ spectra indicate significant non-charm contributions. A search for lepton-number violating decays is made, resulting in upper limits in a number of branching ratios. Also discussed here is the authors work in the DELPHI experiment, contributions that are related to analysis of heavy quark production. (author) (190 refs.)

    Full Text Available Objetivou-se, no presente trabalho, identificar a profundidade de dormência e a velocidade de brotação em gemas de pereira, submetidas a diferentes períodos de frio à temperatura de 4ºC ±1. O experimento foi conduzido na Embrapa-Clima Temperado, em Pelotas, em 1999. Em 1º de junho, foram coletados 50 ramos, na cultivar Carrick, com aproximadamente 30 cm de comprimento. Após, foram divididos em 5 lotes de 10 ramos, sendo 4 mantidos a 4ºC± 1, e um em condições ambiente, constituindo, assim, 5 tratamentos: 0 (Testemunha; 272; 544; 816 e 1088 horas de frio (HF. No final de cada tratamento, os ramos foram divididos em pequenas estacas, contendo apenas uma única gema, sendo, após, armazenados em câmara climática a 25ºC ± 1. Avaliou-se a brotação, considerando-se o estádio de ponta verde. A partir destes dados, calculou-se o tempo médio de brotação (TMB, bem como a percentagem de gemas brotadas, em cada um dos tratamentos. Utilizou-se o índice de velocidade de brotação (IVB, para determinar a eficiência da temperatura na brotação das gemas. A profundidade de dormência, das gemas terminais, diminuiu à medida que se aumentou o período de frio. As gemas axilares não foram influenciadas pelo tempo de exposição ao frio. Com base nos dados do IVB e dos coeficientes angulares, as gemas terminais da cv.

  18. Láser helio-neón combinado con clorhexidina al 0,2 %.: Efectos clínicos y microbiológicos en el tratamiento de la gingivitis crónica

    Tatiana Peña Ruiz

    Full Text Available La gingivitis crónica constituye una de las formas más frecuentes de enfermedad periodontal, caracterizada por la inflamación crónica de la encías, tumefacción, enrojecimiento y sangramiento. Su principal factor de riesgo lo constituye la microbiota del surco gingival, que resulta necesario, pero no suficiente para desencadenarla. Se realizó un ensayo clínico-terapéutico fase II, controlado, aleatorizado y a simple ciegas, para evaluar los efectos clínicos y microbiológicos del tratamiento combinado de la radiación láser helio-neón (He-Ne con la clorhexidina al 0,2 %. Todos los pacientes recibieron tratamiento inicial; al mes de finalizado este, se distribuyeron aleatoriamente en 2 grupos: un grupo estudio que recibió la combinación láser-neón y clorhexidina al 0,2 % y otro grupo control que solo recibió clorhexidina al 0,2 %. Se realizó una evaluación a los 15, 30 y 45 días, con criterios de eficacia clínicos y microbiológicos. Los resultados clínicos fueron satisfactorios en el grupo estudio con predominio de los morfotipos I, caracterizados por cocos gramnegativos y positivos, compatibles con un periodonto sano. Los eventos adversos detectados con esta terapéutica fueron mínimos, todos relacionados con la somnolencia.

    Full Text Available Pulverizações foliares com produtos contendo micronutrientes, dentre os quais os produtos quelatizados, são utilizadas com relativa freqüência em frutíferas, sem o embasamento científico adequado, principalmente entre os agricultores mais tecnificados. Neste contexto, o objetivo deste trabalho foi verificar o efeito da aplicação via foliar de B e Zn sobre a produção e os teores de SST e ATT dos frutos da Pereira-Japonesa e da Pinheira. O experimento foi conduzido numa área irrigada, situada no cinturão verde do município de Ilha Solteira-SP. O solo da área foi classificado como Podzólico Vermelho-Escuro. Foram utilizadas plantas de Pereira-Japonesa, cultivar Okussankichi e de Pinheira. Os tratamentos utilizados foram: T1. apenas água; T2. ácido bórico; T3. sulfato de zinco; T4. T2 + T3; T5. ácido bórico + uréia + ácido cítrico + EDTA; T6. sulfato de zinco + uréia + ácido cítrico + EDTA; T7. T5 + T6; T8. ácido bórico + uréia + ácido cítrico + EDTA + molibdato de sódio + enxofre + cloreto de cálcio; T9. sulfato de zinco + ácido cítrico + EDTA + sulfato de Fe + sulfato de Mn + sulfato de Mg, e T10. T8+T9. Foram utilizadas doses de 110 g ha-1 de B e 250 g ha-1 de Zn, em cada aplicação. O delineamento experimental adotado foi o de blocos ao acaso, com quatro repetições e, para comparação de médias, foi utilizado o teste de Tukey. Com base nos resultados obtidos, pode-se concluir que: 1 a produção e os teores de SST e ATT dos frutos da pereira-japonesa e da pinheira não foram influenciados pela aplicação foliar de B e de Zn; b a mistura de ácido bórico com quelatos foi eficiente no fornecimento de B às plantas de pereira- japonesa, o mesmo não ocorrendo para pinheira, c o sulfato de zinco + produtos quelatizantes foram eficientes no aumento dos teores foliares de Zn somente na pereira.Leaf spray using liquid products with micronutrients, among them, quelates are usual in fruit trees.

    Full Text Available Pesquisou-se, no Instituto Agronômico (IAC, em julho-dezembro de 1993, o desenvolvimento inicial da pereira 'Okussankichi' (Pyrus serotina Rehder, enxertada em plântulas de Taiwan Nashi-C (P. calleryana Decne. nos diâmetros de 4, 6, 8, 10 e 12 mm. Pesquisou-se, ainda, o comportamento de outras oito pereiras em enxertia interespecífica em plântulas de doze meses. Pôde-se observar, por meio da enxertia por garfagem do tipo inglês simples, o adequado comportamento das mudas na fase de junção dos tecidos cambiais, sem que nenhum sintoma de incompatibilidade inicial fosse detectado. As espécies e cultivares estudados apresentaram cerca de 95% de pegamento dos enxertos, comprovado pelas brotações vigorosas emitidas após 45 dias da enxertia. Os porta-enxertos com diâmetros de 10 e 12 mm proporcionaram os maiores índices de crescimento vegetativo: transcorridos quatro meses, os enxertos de 'Okussankichi' já apresentavam excelente padrão de desenvolvimento; com mais de 100 cm de altura, diâmetro próximo a 9 mm e mais de 30 folhas, as mudas estavam aptas a ser plantadas no campo. Nos porta-enxertos com diâmetros de 4 e 6 mm, ocorreu baixo desenvolvimento das mudas, bem inferior ao padrão mínimo desejável. O desenvolvimento dessas pereiras, em campo, está sob contínua investigação; em três anos de cultivo, não se verificaram sinais de incompatibilidade de enxertia.The stock-scion compatibility of nine pear cultivars and species grafted on seedlings stocks of Taiwan Nashi-C (Pyrus calleryana Decne. and the 'Okussankichi' (P. serotina Rehder behavior of five stem diameters were evaluated at the Instituto Agronômico (IAC, State of São Paulo, Brazil.

    Most patients with chronic lymphocytic leukaemia or small lymphocytic lymphoma relapse after initial therapy. Bendamustine plus rituximab is often used in the relapsed or refractory setting. We assessed the efficacy and safety of adding ibrutinib, an oral covalent inhibitor of Bruton's tyrosine kinase (BTK), to bendamustine plus rituximab in patients with previously treated chronic lymphocytic leukaemia or small lymphocytic lymphoma. The HELIOS trial was an international, double-blind, placebo-controlled, phase 3 study in adult patients (≥18 years of age) who had active chronic lymphocytic leukaemia or small lymphocytic lymphoma with measurable lymph node disease (>1·5 cm) by CT scan, and had relapsed or refractory disease following one or more previous lines of systemic therapy consisting of at least two cycles of a chemotherapy-containing regimen, an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, and adequate bone marrow, liver, and kidney function. Patients with del(17p) were excluded because of known poor response to bendamustine plus rituximab. Patients who had received previous treatment with ibrutinib or other BTK inhibitors, refractory disease or relapse within 24 months with a previous bendamustine-containing regimen, or haemopoietic stem-cell transplant were also excluded. Patients were randomly assigned (1:1) by a web-based system to receive bendamustine plus rituximab given in cycles of 4 weeks' duration (bendamustine: 70 mg/m(2) intravenously on days 2-3 in cycle 1, and days 1-2 in cycles 2-6; rituximab: 375 mg/m(2) on day 1 of cycle 1, and 500 mg/m(2) on day 1 of cycles 2-6 for a maximum of six cycles) with either ibrutinib (420 mg daily orally) or placebo until disease progression or unacceptable toxicity. Patients were stratified according to whether they were refractory to purine analogues and by number of previous lines of therapy. The primary endpoint was independent review committee (IRC)-assessed progression

(temperatura de 25ºC, umidade relativa do ar de 90% e fotoperíodo de 8 horas e de telado com irrigação por microaspersão, sem controle ambiental. Em ambiente controlado de estufa, as estacas não-tratadas com AIB iniciaram intensa brotação das gemas e formação de calo após sete dias do plantio. Já em ambiente de telado, essas estacas demoraram 21 dias para o início de brotação das gemas, mostrando menor desenvolvimento de calo. Nas estacas tratadas com AIB, os calos surgiram nas regiões dos cortes após o terceiro dia de incubação na estufa B.O.D. As raízes desenvolveram-se a partir dos tecidos da base e dos calos, tornando-se mais nítidas a partir de 14 e 28 dias, respectivamente, para os ambientes de estufa e de telado. Após 42 dias, o melhor percentual de enraizamento (83% foi verificado no tratamento com AIB a 2.000 mg.L-1, em ambiente de estufa B.O.D. O emprego dessa estufa, com temperatura, luz e umidade relativa controladas, mostrou-se viável em relação ao telado, no processo de enraizamento das estacas lenhosas da pereira 'Limeira', podendo favorecer o sistema de propagação vegetativa da pereira e encurtar o período da formação de mudas.The rooting of cuttings pear under controlled environment of chamber (B.O.D. type and greenhouse was searched.

Se identificaron correlaciones entre la gravedad y el estrato socio-económico. Se hallaron correlaciones positivas entre síntomas de bulimia y las estrategias de autoinculparse y búsqueda de apoyo espiritual. También se encontró correlación positiva entre gravedad y las estrategias de búsqueda de apoyo espiritual y distracción física. Los resultados coinciden parcialmente con estudios previos sobre el tema puesto que las estrategias que se relacionan con los síntomas y gravedad de la bulimia son evitativas y centradas en la emoción.

    Full Text Available Foi avaliada a qualidade de frutos de pêra japonesa cv. Housui (Pyrus pyrifolia var. culta ensacados com diferentes tipos de sacos de papel e em duas épocas: 34 e 83 dias após a florada. O ensacamento não influenciou na firmeza, no teor de sólidos solúveis totais e no peso médio dos frutos. Sacos vermelhos não induziram aumento do pH da polpa, mas o uso de sacos duplos, sacos marrons, sacos de papel kraft marrons e sacos de pipoca brancos aumentaram significativamente o pH. Ao buscar-se maior precocidade de colheita, os melhores resultados foram obtidos com o uso de sacos pequenos de papel manteiga aos 34 dias após a floração e o uso de sacos grandes duplos ou sacos grandes marrons, 83 dias após a plena floração. O ensacamento 34 dias após a plena floração, com sacos grandes de papel duplo de cor marrom ou sacos de papel kraft marrons, ou ainda o uso de sacos pequenos parafinados transparentes de papel manteiga, aos 34 dias, seguidos pela colocação, aos 83 dias, dos dois tipos de sacos grandes citados anteriormente, resultaram em frutos de melhor qualidade externa (película de coloração homogênea e mais clara, lisa e com lenticelas pouco salientes. O uso de sacos vermelhos de papel manteiga e de sacos de pipoca brancos, com ou sem ensacamento prévio com sacos pequenos de papel manteiga parafinado, não resultaram em melhoria substancial da qualidade externa do fruto.The fruit quality of Nashi pears cv. Housui (Pyrus pyrifolia var. culta have been evaluated after bagging with different paper bags at two bagging dates: 34 and 83 days after full bloom. The bagging did not affect the fruit firmness, the total soluble solids and the average fruit weight. Red bags did not affect the pH of the fruit flesh. However the fruit bagged with double bags of brown color, brown kraft paper and white popcorn paper increased the pH. In order to harvest precociously, the use of small transparent paraffin paper bags 34 days after full bloom or the use of large kraft paper bags of brown color and also by using small transparent paraffin paper bags at 34 days followed by the use of a double large bags at 83 days after full bloom, resulted in better fruit appearance (uniform, shine and smooth skin color with small lenticels. The use of red bags and white popcorn bags, with and without previous bagging with small transparent paraffin paper bags did not result on better fruit appearance.

  5. The effect of spatial discretization in LWR cell calculations with HELIOS 1.9

    Merk, B.; Koch, R.

    2008-01-01

    Cell and lattice calculations are the basis for all deterministic static and transient 3D full core calculations. The spatial discretization used for the cell and lattice calculations influences the results for these transport solutions significantly. The arising differences in the neutron flux distribution due to different spatial discretization are demonstrated. These differences in the flux distribution cause significant changes in the kinf value. An evaluation of the kinf value for the case of infinitely fine discretization is made. The influence of the discretization on the calculation of homogenized few group cross sections which are forwarded to the 3D full core calculations is investigated. Strategies for improving the discretization are developed and their influence on the calculation time is evaluated. (Authors)

    Fast visible cameras and a filterscope are used to examine the visible light emission from Oak Ridge National Laboratory’s Proto-MPEX. The filterscope has been configured to perform helium line ratio measurements using emission lines at 667.9, 728.1, and 706.5 nm. The measured lines should be mathematically inverted and the ratios compared to a collisional radiative model (CRM) to determine T{sub e} and n{sub e}. Increasing the number of measurement chords through the plasma improves the inversion calculation and subsequent T{sub e} and n{sub e} localization. For the filterscope, one spatial chord measurement requires three photomultiplier tubes (PMTs) connected to pellicle beam splitters. Multiple, fast visible cameras with narrowband filters are an alternate technique for performing these measurements with superior spatial resolution. Each camera contains millions of pixels; each pixel is analogous to one filterscope PMT. The data can then be inverted and the ratios compared to the CRM to determine 2-dimensional “images” of T{sub e} and n{sub e} in the plasma. An assessment is made in this paper of the candidate He I emission lines for an imaging technique.

    Moore, D.

    1981-03-01

    An instrumented single family residence in Greenville, South Carolina, has approximately 1086 square feet on conditioned space. Solar energy is used for space heating the home and preheating domestic and water (DHW). Solar energy enters the attic through a 416 square foot aperture which is double glazed with corrugated, translucent, fiberglass reinforced, acrylic panels. Warm air accumulates in the peak of the attic roof and circulates through the conditioned space or through storage by an air handler. Solar energy is stored in an 870 cubic foot storage bin containing 85,460 pounds of crushed rock located under the house. cold water is preheated in the attic by thermosiphoning water from the 80 gallon preheat tank through a manifold system of copper tubes. These tubes are attached to black sheet metal plates. Preheated city water is stored in the preheat tank and supplied, on demand, to a conventional 80 gallon DHW tank. When solar energy is insufficient to satisfy the space heating load, a water to air heat exchanger in the hot air supply duct provides auxiliary energy for space heating. A gas fired water heater provides auxiliary energy for the water to air heat exchanger and the DHW.

  18. Mirror position display equipment for the target chamber mirror mounts of the LASL HELIOS laser fusion facility

    Wells, F.D.; Remington, D.A.

    1979-01-01

    Equipment has been fabricated which records the absolute positions of sixteen mirror mounts used to direct and focus eight high-energy laser beams for research in laser induced fusion. Each mirror mount is driven by three stepping motors, controlled to produce the motions of Focus, Tilt, and Rotate relative to the target. Stepping of the motors is sensed by incremental optical encoders coupled to the motor drive shafts. Outputs from the encoder tracks are multiplexed to a microprocessor which transmits motor step information via a fiber optical data link to a Mirror Position Display chassis. This unit accumulates the steps, stores the motor positions, displays mirror position data to the operator, and provides the equipment control functions. Standby battery power is included to retain the motor step data in the event of power failure

  19. On the influence of spatial discretization in LWR steady state and burnup calculations with HELIOS 1.9

    Merk, B.; Weiss, F. P.

    2009-01-01

    Cell and burnup calculations are fundamental to all deterministic static and transient 3D full core calculations for different operational states of the reactor. The spatial discretization used for the cell and burnup calculations influences significantly the results of full integral transport solutions. The influence of the discretization on k inf is shown for the steady state case and the influence on the neutron spectrum is analyzed. Moreover, the differences in k inf are presented for different spatial discretization strategies in the burnup calculation of Uranium Oxide (UOX) fuel. The resulting different flux distributions cause significant changes in the isotopic densities. The influence of the discretization strategies on the calculation of homogenized few group cross-sections is investigated. This detailed discretization study demonstrates the need for sufficiently fine discretization to produce reliable and accurate results when using integral transport methods. In contrast to the currently used discretization schemes, refined discretization is especially important in the moderator region of the unit cell to reproduce the influence on the thermal neutron spectrum. Additionally, the need for sufficient discretization affects the idea of full core calculations based on integral transport methods since it has to be discussed whether it is worth to do full core calculations with reduced discretization when facing this strong discretization effect. The computer resources required for full core calculations with fine discretization are currently not available. (authors)

  1. Efectos difusivos en la formación de enanas blancas de Helio de baja masa en sistemas binarios cerrados

    De Vito, M. A.; Benvenuto, O. G.

    In the last years, and thanks to advances in observational techniques, many astronomers have discovered in a great number of binary radio-pulsars the presence of a helium white dwarf resulting from a previous evolutionary state in which the progenitor of this star experienced one or more episodes of mass transfer to the compact component in the pair. That is the case for PSR B1855+09 (van Kerkwijk, M. H., Bell, J. F, Kaspi, V. M., & Kulkarni, S. R. 2000, ApJ 530, L37), where the mass for the white dwarf is known accurately from measurements of the Shapiro delay of the pulsar signal, MWD = 0.258+0.028-0.016 M⊙; for PSR J02018 + 4232 (Bassa, C. G., van Kerkwijk, M. H., & Kulkarni, S. R. 2003, A&A, 403, 1067), the spectra confirm that the companion is a helium-core white dwarf of ≈ 0.2 M⊙. On the other hand, there are several authors (Ferraro, F., Possenti, A., Sabbi, E., & D'Amico, N. 2003, ApJ, 596, L211; Bassa et al. 2003) that have identified the optical binary companion to the BMSP PSR J1911 - 5958A, located in the halo of the Galactic globular cluster NGC 6752, like a blue star whose position in the color-magnitude diagram is consistent with the cooling sequence of a low-mass, ≈ 0.17 - 0.20 M⊙, low metallicity helium white dwarf at the cluster distance. Finally, the color and magnitude of the stellar companion for B 1620-26 indicate that is a white dwarf of 0.34 ± 0.04 M⊙ (Sigurdson, S., Richer, H. B., Hansen, B. M., Stairs, I. H. & Thorset, S. E. 2003, Science, 301, 193S). This has motivated us to study the formation of low mass helium white dwarfs in the context of binary evolution. For that purpose, using the code of binary evolution, entirely developed in the Facultad de Ciencias Astronómicas y Geofísicas of the Universidad Nacional de La Plata, Argentina, we have investigated the effects of diffusive processes on the evolution of a star member of a close binary system. A similar study was performed for Althaus, L. G., Serenelli, A. M., & Benvenuto, O. G. (2001, MNRAS, 323, 471) but in that paper the mass transfer was mimicked by subtracting mass to a progenitor of 1 M⊙ to obtain the mass for the desired object. Actually, our binary code has a full nuclear reactions network for hydrogen and helium burning that allowed us to follow the abundances of fifteen isotopes throughout the entire evolution of the star. We have also included a detailed equation of state. The mass loss treatment is non conservative. We have modified the conditions for the beginning and end of mass transfer episodes. In our previous version, we assumed it to occur when the stellar radius was greater or smaller, respectively, that the Roche Lobe radius for the star. This introduced numerical problems, especially at the end of mass transfer phases. We adopted H. Ritter (1988, A&A, 202, 93) formulation that considers a finite scale height in the stellar atmosphere. The numerical behaviour in much more satisfactory, besides that it constitutes a more appropriate description for the physical problem. We perform the calculations for the evolution of the primary star in a close binary system of initial mass 2 M⊙, initial period of 1 day, initial mass ratio of 1.4142 and solar metallicity. We have done the calculations in four cases: A) with diffusion and all Roche Lobe overflows, B) with diffusion and only the first Roche Lobe overflow, C) without diffusion and all Roche Lobe overflows, D) without diffusion and only the first Roche Lobe overflow. Cases B) and D) where performed to compare with results obtained for Althaus et al. (2001). The main conclusion of this work is that the age of these objects is mainly determined by diffusive effects, and the late stages of mass transfer, not considered in Althaus et al. (2001), constituted a minor effect on the scales of cooling times.

    Full Text Available Pouco se conhece sobre métodos para cultivo de Tillandsia kautskyi. Este estudo teve o objetivo de observar o desenvolvimento de plantas dessa espécie em substratos de origem vegetal, tendo como padrão uma mistura contendo xaxim. O experimento foi conduzido entre dezembro de 2000 e abril de 2002, em Jaboticabal (SP, em casa de vegetação com 70% de interceptação da luz solar. As mudas foram cultivadas em vasos plásticos, preenchidos com diferentes substratos: S1 = 45% de xaxim + 45% de fibra de coco + 10% de húmus de minhoca; S2 = 45% de fibra de coco + 45% de casca de Pinus + 10% de húmus de minhoca; S3 = 100% de fibra de coco com adição de macro e micronutrientes; S4 = 100% de fibra de coco. Houve diferença significativa apenas para o desenvolvimento do sistema radicular, maior em S3 do que em S2. Cálculos de regressão linear indicaram que as causas prováveis do menor desenvolvimento das raízes em S2 foram: maior densidade desse substrato, menor teor de matéria orgânica total, menor umidade natural, menores teores de potássio e boro, e concentrações mais altas (possivelmente tóxicas de fósforo (0,19% de P2O5, ferro (42.086 mg/kg e manganês (385 mg/kg. Concluiu-se que T. kautskyi pode ser cultivada em substratos que não contêm xaxim, e que substrato constituído por 100% de fibra de coco é um bom substituto para misturas contendo xaxim.

    Full Text Available Os objetivos deste trabalho foram estudar as relações solo-paisagem em uma litosseqüência de transição arenito-basalto e verificar a similaridade dos limites de superfícies geomórficas mapeados no campo com os limites mapeados a partir de técnicas geoestatísticas. Foi realizado o mapeamento de uma área de 530 ha, utilizando-se equipamento de GPS, e em seguida elaborou-se o Modelo de Elevação Digital, que possibilitou o estabelecimento da transeção de 2.100 m a partir do topo. Ao longo da transeção, o terreno foi estaqueado a intervalos regulares de 50 m, nos quais foram realizadas medidas da altitude para confecção do perfil altimétrico. As superfícies geomórficas foram identificadas e delimitadas conforme critérios topográficos e estratigráficos, com base em intensas investigações de campo. Coletaram-se amostras de solo em pontos laterais em 67 locais, nas superfícies geomórficas identificadas, nas profundidades de 0,0-0,25 m e 0,80-1,00 m. Além disso, foram abertas trincheiras nos segmentos de vertente inseridos nas superfícies geomórficas mapeadas. As amostras coletadas foram analisadas quanto a densidade do solo, textura, Ca2+, K+, Mg2+, SB, CTC, V, pH (água e KCl, SiO2, Al2O3 e Fe2O3 (ataque por H2SO4, óxidos de Fe "livres" extraído com ditionito-citrato-bicarbonato e ferro mal cristalizado extraídos com oxalato de amônio. A fração argila desferrificada foi analisada por difração de raios X. A compartimentação da paisagem em superfícies geomórficas e a identificação do material de origem mostraram-se bastante eficientes para entendimento da variação dos atributos do solo. A análise individual desses atributos por meio de estatística univariada auxiliou na discriminação das três superfícies geomórficas. O uso de técnicas de geoestatística permitiu a confirmação de que mesmo os atributos do solo apresentaram limites próximos aos das superfícies geomórficas.The focus of our study were to study soil-landscape relationships in a sandstone-basalt transition lithosequence and to compare the limits of geomorphic surfaces mapped in the field with those mapped by geostatistical techniques. An area of 530 ha was mapped using GPS equipment in order to generate a model of digital elevation, which allowed for the establishment of a transection of 2.100 m from the hill top downwards. Along the transection, the altitude was measured at 50 m regular intervals to construct the elevation profile. The geomorphic surfaces were identified and delimited according to topographic and stratigraphic criteria based on detailed field investigations. Soil samples were collected at 67 points of the identified geomorphic surfaces, in the 0.0-0.25 m and 0.80-1.00 m depths. Besides, trenches were opened in the slope segments of the mapped geomorphic surfaces. The samples were analyzed for bulk density, texture, Ca, K, Mg, SB, CEC, V%, pH (water and KCl, SiO2, Al2O3 and Fe2O3 (H2SO4 attack, and "free" iron oxides extracted with dithionite-citrate-bicarbonate, while poorly crystallized iron was extracted with ammonium oxalate. The iron-free clay fraction was analyzed by x-ray diffraction. The compartmentalization of the area in geomorphic surfaces and the identification of the parent material explained well the variation in the soil attributes. An individual analysis of the soil attributes by univariate statistics contributed to the discrimination of the three geomorphic surfaces. Geostatistical techniques confirmed the agreement of the limits determined by individualized soil attributes with those of the geomorphic surfaces.

    2010-01-01

    We present the time distribution of a large number (7798) of Myocardial Infractions (MI) recorded at the General Hospital `St. Panteleimon' of the city of Nikea (in Piraeus, Greece), during time interval 1997-2007. This data set consisted of 5160 NON-STEACS (non-ST) and 2638 STEACS (ST) infractions are examined along with the monthly numbers of solar flares and Coronal Mass Ejections (CMEs), solar wind parameters and the geomagnetic activity (Dst geomagnetic index and other). The mean monthly value of ST and non-ST events is 20 and 40 respectively. The maximum monthly value of non-ST events (72 and 73) are recorded in October 2002 and January 2003, as well as the one of ST events (32), while solar maximum, recorded in November 2002. This time interval is characterized by magnetic storms from August 2002 peaked in October 2002 and ended in February 2003. It is noticeable that August 2002 corresponds to the solar maximum of CMEs and strong solar flares monthly values. The maximum monthly value of ST events (40) is recorded in November 2005 almost simultaneously with a sudden absence of solar flares (October 2005). Increased values have been recorded during a period of extreme solar events of October-November 2003 and January-March 2005. It seems from this extensive statistical study that there is an association between the monthly values of MI and of CMEs; the non-ST MI shows a better association with CMEs. Moreover, the MI yearly distribution is in accordance with the time distribution of magnetic storms (number and duration). The non-ST distribution is also affected by intense magnetic storms.

    We discuss the results of the long-term telecommunicative biogeophysical monitoring "Geliomed" (2003-2010). The purpose is to explore the effects of spatial and temporal variations in space weather and climatic factors on the human health state. The monitoring is carried out simultaneously at the different geographical areas that covers the different latitudes. The project developed in the joint collaboration the Ukrainian National Academy of Science and the Russian Academy of Science. The experiment carried out simultaneously in Moscow, Yakutsk, Kiev and Simferopol. The principal components of the experiment can be summarized as follows: 1. Equipments and data gathering methods are the same for all the scientific cen-ters which are involved in experiment. Research centers working with the same equipment and using the same protocols with on-line registration of current data on same portal server (http//geliomed.immsp.kiev.ua) 2. The groups of patients involved in the program are kept the same for the whole observational period of time. 3. The daily registered parameters in-clude: psycho-emotional tests and 1-st lead ECG (contain 25 000 measurements for the whole period), arterial pressure (100 000 measurements), variability cardiac contraction (25000 mea-surements), electric conduction of bioactive points on skin (more than 500 000 measurements for the whole period ). 4. The every patient in the monitoring group is examined at the 4 functional states. Registration is done at rest, after standard psychology test, Roufiet test, and after 10 min relax. 5. The data of the ECG measurements are analyzed in the phase space constructed from the signal and its derivative. 6. The results time series were compared with daily values of space weather and geomagnetic parameters. Results. In the all monitoring centers all the patients involved in the monitoring show the same type of changes in the cardiac activity parameters during an isolated magnetic storm. Such a change of the ECG parameters occurs nearly simultaneously for all the centers. The higher latitude, the greater amplitude of the ECG parameters change. The properties of the detected phenomena can be summarized as follows: -The dynamics of adaptation programs changes during the storm. The maximum amplitude of change is observed for the healthy patients. -The number of none-typical ECG beats increase; -There are no clear evidences for variations of RR intervals during geomagnetic storms. -Man are more sensitive to magnetic storms, while endogenous rhythms predominate for females; Additionally, we find, that the embedding of ECG time series in 3D phase space can be considered as a mix of a few states. At the rest, the occurrence of the basic ECG state compare to additional ones is about 8:2. The occurrence of the basic state increases after the stress. Thus, the external stress may change the relative disorder of the system. To understand the origin of the standard cardio-cycle changes we reconstruct of the dynamical model of the individual cardiac beat. The reconstruction reveals that the typical evolution of the cardiac rhythm includes the drift of attractor in the embedding space and the sudden change between a few basic patterns of attractor. However one of pattern is always dominating. These several pattern of ECG beat attractor can be ascribed to a several states of the system. Qualitatively, the nonlinear ECG dynamics is defined by the stationary points, which are inside into Q and T waves. Conclusions: many-year telecommunication heliomedical monitoring in different lat-itudes showed, that space and geophysical factor act as a training factor for the adaptation-resistant member of the population. It serve as a channel for rejection of nonviable members of the population, synchronize the total populations rhythms, create conditions for generation of new information in the process of evolution adaptation of biological systems in general.

    In this paper we study the capture of a negative muon by H{sub e}{sup 3} in the channel {mu}-+H{sub e}{sup 3}+V. Following Primakoff we use the V-A theory of the weak interactions. We include also first order relativistic terms. To describe the initial and final nuclei we have used the most general wave function allowed by the Paul is exclusion principle, assuming that these nuclei are a mixture of an isospin doublet and quadruplet. For the part of the wave function depending on the inter nucleonic distances, we have taken four different function without hard-core, a gaussian and three kinds of Irving type. We present in several tables the results obtained varying g{sub p}/g{sub v} and g{sub A}/g{sub y} as well as the amplitudes of the fourteen terms forming the nuclear wave function. (Author) 35 refs.

    2018-07-01

    Our study in the Journal of Sports Sciences was originally designed to test whether the bar-velocity is a precise indicator of the power training intensity (i.e., optimum loads) in different exercises commonly included in athletes' training programs. Furthermore, we presented secondary findings, related to the actual results obtained in our assessments. As a cross-sectional study with clear objectives, we focused on discussing issues and applications pertaining to neuromuscular training interventions, such as: (1) describing the advantages of using bar-velocities to control the power training intensity, (2) defining a range of loads capable of maximizing the power production in certain ballistic and traditional exercises, and (3) revealing the differences between these exercises and the respective implications for training. Fundamentally, we did not produce a mechanistic investigation and were very accurate and consistent in reporting our data, collected under rigorous and well-established experimental conditions. Here we provide our point-by-point comments to the concerns raised in the "Letter to the Editor", along with some theoretical explanations about the secondary findings reported by the authors of the Letter. To better understand the nature and purposes of our experiment, we also present a series of practical examples and review previous investigations involving the "bar-power" approach.

    2018-05-01

    Loturco and co-workers (2017) recently published data in the Journal of Sports Sciences to present the optimum loading magnitudes regarding the maximization of the "mean propulsive power" of the leg and arm muscles. Among the most important findings were that (1) the recorded power in the squat and squat jump exercises was markedly low, (2) the optimum external load that maximized the power in the same exercises was close to 100% of body weight, while (3) the ballistic bench press throw revealed smaller power than the regular bench press typically performed with relatively low level of muscle activation towards the end of the propulsive lifting phase. The findings are either counter-intuitive, or contradict the literature findings, or both, and we believe that they originate from apparent methodological flaws. The first one is neglecting the force acting against the body segments moved together with the external load that is particularly high in squat exercises. The second one is an erroneous calculation of the propulsive phase that included a part of the bar's flight time. Both of these methodological flaws are frequent in the literature and could be associated with the improper use and calculation of variables when utilizing linear position transducers.

  14. Relative thermoluminescent efficiencies proton/gamma and helium/gamma of peaks of high temperature in TLD-100 dosemeters; Eficiencias termoluminiscentes relativas proton/gamma y helio/gamma de picos de alta temperatura en dosimetros TLD-100

    2007-07-01

    The increase of the applications of ion beams in radiotherapy treatments has generated interest in the study of the thermoluminescent materials (TL) that allow to determine the applied doses. A way to quantify the TL response from these materials to ions is by means of the relative thermoluminescent efficiency. In the group of Thermoluminescent dosimetry of the Institute of Physics of the UNAM (IFUNAM) the thermoluminescent response of the TLD-100 dosemeters has been studied, which present a glow curve characteristic with several peaks that correspond to traps and luminescent centers in the material. The stable peaks know each other as 4, 5, 6a, 6b, 7, 8, 9 and 10. The efficiencies should be measured using the response so much to the radiation of interest (in this case protons and helium ions) as the response to gamma radiation. In previous works with ions of low energy taken place in the Pelletron accelerator of the IFUNAM was only measured the TL efficiency for the peak 5 and the total signal. It had not been possible to measure the efficiency of the peaks of high temperature (6a-10) because, for the gamma radiation, the peaks of high temperature show very small signals; however, recently Massillon carries out measures of efficiency TL of peaks of high temperature for ions of intermediate energy using a protocol special of reading and of deconvolution that allows to measure the signals coming from the peaks of high temperature. In this work is implemented this same protocol to complete the study of TL efficiencies at low energy of protons and helium and to determine if the values of efficiency depend on the used reading protocol. For it is reported it measures of the relative efficiency of the peaks of high temperature from the TLD-100 exposed to protons of 1.5 MeV and nuclei of helium of 3 and 7.5 MeV. (Author)

Materials and methods: This was a prospective, observational, multicenter, open-label study of 0.5 mg of ranibizumab administered intravitreally. Patients were followed over 24 ± 3 months with intermediate data points at 6 ± 2 months and 12 ± 2 months, and a limited data point at 2.5 ± 1 month that coincided with the end of the loading phase. Outcomes included visual acuity (Early Treatment Diabetic Retinopathy Study, visual function (National Eye Institute Visual Function Questionnaire-25 [NEI VFQ-25], quality of life (Health Utilities Index Mark III [HUI3], and safety. Results: A total of 267 patients with wet age-related macular degeneration (mean ± standard deviation [SD] age = 78.5 ± 7.3 years; 62.4% were female; 34.5% with dual eye involvement; 74.9% were treatment-naïve were treated (309 eyes were treated.

The mean visual acuity increase over baseline at 12 months was not significant (P = 0.08; the decline over baseline at 24 months statistically significant (P = 0.02. Overall, 94.3% of patients showed stable or improved disease at 6 months and 81.5% of patients showed stable or improved disease at 24 months. At 6 months, improvements over baseline were significant for VFQ-25 (P = 0.03 and HUI3 (P = 0.02, but not at 12 months and 24 months. Improvements in VFQ-25 and HUI3 were maintained at 24 months in 38% and 34% of patients, respectively. In total 78 serious adverse events were reported in 40 patients and 77 nonserious adverse events in 34 patients. Nine serious adverse events and nine nonserious adverse events in 14 patients were suspected to be related to ranibizumab treatment. Conclusion: The "real-world" clinical effectiveness of ranibizumab was evidenced by the initial improvements over baseline in visual acuity and quality of life, as well as the maintenance of these outcomes at baseline levels at 24 months, and this was observed under variable treatment conditions. The findings underscore the need for individualized treatment with regular monitoring to achieve optimal vision and quality of life outcomes.

  17. Thermal fluid dynamic behavior of coolant helium gas in a typical reactor VHTGR channel of prismatic core; Comportamento termofluidodinamico do gas refrigerante helio em um canal topico de reator VHTGR de nucleo prismatico

    Belo, Allan Cavalcante

    2016-08-01

    The current studies about the thermal fluid dynamic behavior of the VHTGR core reactors of 4{sup th} generation are commonly developed in 3-D analysis in CFD (computational fluid dynamics), which often requires considerable time and complex mathematical calculations for carrying out these analysis. The purpose of this project is to achieve thermal fluid dynamic analysis of flow of gas helium refrigerant in a typical channel of VHTGR prismatic core reactor evaluating magnitudes of interest such as temperature, pressure and fluid velocity and temperature distribution in the wall of the coolant channel from the development of a computer code in MATLAB considering the flow on one-dimensional channel, thereby significantly reducing the processing time of calculations. The model uses three different references to the physical properties of helium: expressions given by the KTA (German committee of nuclear safety standards), the computational tool REFPROP and a set of constant values for the entire channel. With the use of these three references it is possible to simulate the flow treating the gas both compressible and incompressible. The results showed very close values for the interest quantities and revealed that there are no significant differences in the use of different references used in the project. Another important conclusion to be observed is the independence of helium in the gas compressibility effects on thermal fluid dynamic behavior. The study also indicated that the gas undergoes no severe effects due to high temperature variations in the channel, since this goes in the channel at 914 K and exits at approximately 1263 K, which shows the excellent use of helium as a refrigerant fluid in reactor channels VHTGR. The comparison of results obtained in this work with others in the literature served to confirm the effectiveness of the one-dimensional consideration of method of gas flow in the coolant channel to replace the models made in 3-D for the pressure range and temperature used in the project since the results obtained were almost the same in the same operating conditions.

    In this paper the implantation with monoenergetic ions (He{sup +}) was realized with an energy of 5 KeV in iron samples (99.9999 %) EFDA (European Fusion Development Agreement) using a collimated beam, after this a Thermal Desorption Spectrometry of Helium (THeDS) was made using a leak meter that detects amounts of helium of up to 10{sup -}- {sup 12} mbar l/s. Doses with which the implantation was carried out were 2 x 10{sup 15} He{sup +} /cm{sup 2}, 1 x 10{sup 16} He{sup +} /cm{sup 2}, 2 x 10{sup 16} He{sup +} /cm{sup 2}, 1 x 10{sup 17} He{sup +} /cm{sup 2} during times of 90 s, 450 s, 900 s and 4500 s, respectively. Also, using the SRIM program was calculated the depth at which the helium ions penetrate the sample of pure ion, finding that the maximum distance is 0.025μm in the sample. For this study, 11 samples of Fe EFDA were prepared to find defects that are caused after implantation of helium in order to provide valuable information to the manufacture of materials for future fusion reactors. However understand the effects of helium in the micro structural evolution and mechanical properties of structural materials are some of the most difficult questions to answer in materials research for nuclear fusion. When analyzing the spectra of THeDS was found that five different groups of desorption peaks existed, which are attributed to defects of He caused in the material, these defects are He{sub n} V (2≤n≤6), He{sub n} V{sub m}, He V for the groups I, II and IV respectively. These results are due to the comparison of the peaks presented in the desorption spectrum of He, with those of other authors who have made theoretical calculations. Is important to note that the thermal desorption spectrum of helium was different depending on the dose with which the implantation of He{sup +} was performed. (Author)

  19. He-Ne laser effects on blood microcirculation. An in vivo study through laser doppler flowmetry; Efeito do laser de helio neonio sobre a microcirculacao sanguinea durante a reparacao tecidual. Estudo in vivo por meio de fluxometria laser doppler

    Blood microcirculation performs an important function in tissue repair process, as well as in pain control, allowing for greater oxygenation of the tissues and the accelerated expulsion of metabolic products, that may be contributing to pain. Low Intensity Laser Therapy (LILT) is widely used to promote healing, and there is an assumption that it is mechanism of action may be due to an enhancement of blood supply. The purpose of this study was to evaluate, using laser Doppler flowmetry (LDF), the stated effects caused by radiation emitted by a He-Ne laser ({lambda}=632.8 nm) on blood microcirculation during tissue repair. To this end, 15 male mice were selected and received a liquid nitrogen provoked lesion, above the dorsal region, and blood flow was measured periodically, during 21 days. Due to radiation emission by the LDF equipment, a control group was established to evaluate possible effects caused by this radiation on microcirculation. To evaluate the He-Ne laser effects, a 1.15 J/cm{sup 2} dose was utilized, with an intensity of 6 mW/cm{sup 2}. The results obtained demonstrate flow alterations, provoked by the lesion, and subsequent inflammatory response. There was no statistical difference between the studied groups. As per the analysis of the results there is no immediate effect due the radiation emitted by a He Ne laser on microcirculation, although a percentage increase was observed in day 7 on medium blood flow rate in irradiated specimens. New studies are necessary to validate the use of this wavelength, in order to promote beneficial alterations in blood supply in radiated areas. (author)

  8. Detail analysis of tritium permeation in the metal liquid channels of the regenerating sheaths of a fusion reactor in presence of helium bubbles; Analisis de detalle de la permeacion de tritio en los caneles de metal liquido de las envolturas regeneradoras de un reactor de fusion en presencia de burbujas de helio

    Inside the channels of liquid metal of the fusion reactor regenerative wrappers, the possible existence of nucleated helium bubbles is not remote. Helium is formed joined the tritium in the escaped neutrons of plasma with lithium. The accumulation of helium in the contact surfaces, between the structure and ML, lead a reduction of heat transfer, at the same time a reduction in the permeation of tritium. The coexistence of three phases in touch: metal liquid, helium and structural material, makes the transport of heat and tritium in a complex phenomenon. To enrich tritium transport studies conducted in the past, there is now a detail analysis of the helium bubble environment adhered to the channel ML wall of a regenerative wrap. For the study we used a CFD tool development on free code OpenFOAM.

    2013-07-01

    In the channels of liquid metal (ML) regenerating sheaths of a fusion reactor, the possibility of bubbles of helium is not remote. Bubbles adhering to the wall of the ML channels would affect heat transfer and the permeation of tritium. Detailed analysis has been conducted (fine mesh), using OpenFOAM, from the environment of a bubble attached to the wall and has developed a model for permeation of tritium through a partially covered with bubbles of helium surface of contact Ml-solid. The model developed has implemented as wall function in OpenFOAM, has validated and has been applied to a case study, using a relatively thick mesh. The developed model substantially reduces the need for computing on the detailed calculation power.

    Full Text Available RESUMO: A proteinose alveolar pulmonar é uma doença rara cuja etiologia ainda permanece desconhecida. É caracterizada pelo preenchimento alveolar por um material proteináceo que determina um quadro pulmonar restritivo com hipoxemia e várias alterações radiológicas. Neste trabalho são analisadas e discutidas as alterações encontradas nas tomografias computadorizadas de alta resolução de doze pacientes com proteinose alveolar pulmonar. Seis casos eram da forma primária da doença, e os outros seis da secundária, estando associados à silicose, asbestose, leucemia, síndrome da imunodeficiência adquirida e lúpus eritematoso sistémico. O objectivo básico foi estudar as alterações tomográficas mais frequentes. Na maioria dos casos, os aspectos tomográficos foram correlacionados com os dados anatomopatológicos, provenientes de biópsias cirúrgicas ou necropsia. Os aspectos tomográficos mais frequentes foram as opacidades em vidro fosco, com distribuição geográfica, associadas a espessamento liso dos septos interlobulares, resultando no padrão de pavimentação em mosaico. Estas alterações foram encontradas em todos os pacientes com a forma primária, não predominando em nenhuma região pulmonar específica. Na forma secundária, cinco dos seis casos apresentavam alterações tomográficas não observadas na forma primária da doença como, por exemplo, placas pleurais, derrame pleural, nódulos centrolobulares, linfonodomegalias e padrão de vidro fosco sem associação com espessamento de septos interlobulares. Além disto, em três destes casos houve um predomínio das lesões nas regiões póstero-inferiores dos pulmões.REV PORT PNEUMOL 2002; VIII(4: 303-314 ABSTRACT: Pulmonary alveolar proteinosis is a rare condition and it’s etiology remains unknown. It is characterized by the accumulation of a proteinaceous material within alveolar spaces resulting in restrictive lung function, hypoxemia and a variety of radiological features. We studied high-resolution computed tomography patterns of twelve patients with pulmonary alveolar proteinosis. Six of them presented secondary forms associated with silicosis, asbestosis, leukemia, acquired immunodeficiency syndrome and systemic eritematous lupus. The purpose of our study was to determine the most frequent tomographic aspects of the disease. In most cases, the tomografic aspects were compared to anatomopathological findings of surgical biopsies or necropsies. The most frequently tomographic aspects observed were ground glass opacities in a geographical distribution associated to smooth interlobular septa thickening resulting in a crazy paving pattern. These patterns were found in all primary form patients and did not have a specific zonal distribution. In five of the six cases of secondary form, we also observed tomographic patterns not shown in primary forms such as pleural opacities, pleural effusion, centrolobular nodules, lymph node enlargement and ground glass opacities without interlobular septa thickening. Furthermore, three cases present a lower and posterior lung zonal predominance.REV PORT PNEUMOL 2002; VIII(4: 303-314 Palavras-chave: Proteinose alveolar, TCAR, pulmões, Key-words: Alveolar proteinosis, HRCT, lungs

  2. Technique using axicons for generating flat-top laser-beam profiles

    Viswanathan, V.K.; Woodfin, G.L.; Stahl, D.; Carpenter, J.P.; Kyrala, G.

    1983-01-01

    In certain fusion experiments using CO 2 lasers, like Helios, it is desired to produce a focal spot several times larger than the nominal focal spot, with a flat beam profile. The typical focal spot in Helios is roughly 70 μm and just defocussing the beam produces beam breakup, with several hot spots with roughly the original diameter, and a gaussian distribution. A number of schemes were tried to achieve a large spot with desired characteristics. These are described in the article. Axicons were found to produce spots with desired characteristics. Axicons are lenses or mirrors having a cone-shaped surface. The various schemes are described, as well as an experiment in Helios which confirmed that axicons produced the spots with desirable characteristics. Helios is an 8-beam CO 2 laser which produces 10 kJ at power in excess of 20 TW. It is currently being used for Laser Fusion studies at the Los Alamos National Laboratory

    The magnetized plasma of the solar corona was remotely sounded using the Faraday rotation effect. The solar magnetic field together with the electrons of the coronal plasma cause a measurable Faraday rotation effect, since the radio waves of Helios are linearly polarized. The measurement is performed at the ground stations. Alfven waves traveling from the Sun's surface through the corona into interplanetary space are observed. Helios 2 signals penetrating through a region where coronal mass is ejected show wavelike structures.

  8. Overvoltage protection by point-plane spark gaps

    Scarlett, W.R.; Riepe, K.B.

    1979-01-01

    In electron-beam-controlled discharge CO 2 lasers, such as those used in the Antares and Helios laser-fusion drivers at the Los Alamos Scientific Laboratory (LASL), protection needs to be provided against possible damage due to overvoltage. A passive (self-breakdown) point-plane spark gap has been developed and successfully used in the Helios power amplifiers which operate at voltages up to 300 kV. A gap of similar design is planned for use in the Antares power amplifiers which operate at 550 kV. These gaps must reliably hold off the normal discharge voltage, but break down with short delay if overvoltaged, diverting the discharge energy to a resistor. A prototype of the Antares gap has been built and is undergoing tests. Parameters being investigated include voltage polarity, gap spacing, gas composition, and gas pressure. Results of these measurements and the operational experience of the Helios gaps will be presented

  9. DRAGON analysis of MOX fueled VVER cell benchmarks

    Marleau, G.; Foissac, F.

    2002-01-01

    The computational unit-cell benchmarks problems for LEU and MOX fueled VVER-1000 ('water-water energetic reactor') have been analyzed using the code DRAGON with ENDF/B-V and ENDF/B-VI based WIMS-AECL cross section libraries. The results obtained were compared with those generated using the SAS2H module of the SCALE-4.3 computational code system and with the code HELIOS. Good agreements between DRAGON and HELIOS were obtained when the ENDF/B-VI based library was considered while the ENDF/B-V DRAGON results were generally closer to those obtained using SAS2H. This study was useful for the verification of the DRAGON code and confirms that HELIOS and DRAGON have a similar behavior when compatible cross sections library are used. (author)

  10. Rudi Stamm'ler contributions and Dragon - 041

    Roy, R.; Marleau, G.; Hebert, A.

    2010-01-01

    The lattice code DRAGON has been in constant development over the last 25 years. During this period, the DRAGON development team has often been directly influenced by the excellent work of Rudi Stamm'ler. First, his book on reactor physics has inspired a large number of programming and calculation techniques that were implemented in DRAGON. Then, the work of Rudi and his collaborators on the lattice code HELIOS, has also prompted a friendly competition that lead us to continuously improve our code in such a way that it could match the performance achieved by HELIOS. This paper provides a description of some characteristics or technologies implemented in DRAGON that were influenced by the work of Rudi Stamm'ler. It also describes a Candu simulation exercise where the capabilities of the HELIOS and DRAGON codes were combined. (authors)

  12. Change of color in resins by adding layers of color 'enamel'

    Lafuente Marin, David; Arce Navarro, Hilda

    2007-01-01

    The quantification of the color change is proposed at the time of employing enamel resin over dentine resin. Six resins color dentin and two color enamel were used. Five discs of resin were built of each resin, with a deameter of 10 mm and a thicjness of 2 mm. The reflectance spectrophotometer Color-Eye ® 7000-A were used, to obtain the values L*, a*, b* of the dentin resin disks and transposition of these with enamel. The conclusion has been that in the color have produced changes clinically detectable when put layers of enamel. The Resin Helio Fill Transparent has been which has produced major changes. Given the two enamel resins, dentin resin Helio Molar 310/B3 has been which has suffered major changes and Helio Fill A2 which has introduced fewer changes. Most resins have decreased the chroma, less the value. (author) [es

  14. Fire impacts on European Boreal soils: A review

    Pereira, Paulo; Oliva, Marc; Cerda, Artemi

    2016-04-01

    Fire is an important natural disturbance in boreal ecosystems, fundamental to understand plant distribution (Ryan, 2002; Wallenius et al., 2004; Granstrom, 2001). Nevertheless, nowadays the intense and successful, fire suppression measures are changing their ecological role (Pereira et al., 2013a,b). This is consequence of the lack of understanding of stakeholders and decision makers about the role of the fire in the ecosystems (Mierasukas and Pereira, 2013; Pereira et al., 2016). This fire suppression measures are increasing the amount of fuel accumulation and the risk of severe wildfires, which can increase of frequency and severity in a context of climate change. Fire is a good tool for landscape management and restoration of degraded ecosystems (Toivanen and Kotiaho, 2007). Fire is considered a soil forming factor (Certini, 2014) and in boreal environments it has been observed that low fire severities, do not change importantly soil properties, mean fire severities induce positive impacts on soil, since add an important amounts of nutrients into soil profile and high severity fires had negative impacts due to the high consumption of organic matter (Vanha-Majamaa et al., 2007; Pereira et al., 2014).

  16. Dynamic radio bursts associated with important flare activity in Hale region 16923 and the problem of the relative locations of type II 'slow drift' bursts and coronal transients

    Mckenna-Lawlor, S.M.P.

    1983-03-01

    Seven type-II radio bursts associated with solar flares in the Hale region 16923 on June 27-29, 1980, are characterized on the basis of data from dynamic radio spectra, white-light observations, radioheliograms, SMM-C/P observations, and Helios I magnetic-field and solar-wind measurements. The data are summarized in tables and graphs and discussed in terms of transient events occurring in the same region. The magnetic shock waves recorded during the period by Helios are described, and channeling effects which may have prevented the detection of type-II burst shocks are examined.

  17. [Virchowian Hansen's disease, Lucio's phenomenon, cryptococcosis].

    1988-12-01

    A 75 years old white male, for 3 years on treatment for virchowian hanseniasis, was admitted with active HD lesions, infiltration on the base of right lung, leg ulcer and malaise. After two days he developed purpura and hemorrhagic blisters in the limbs. The biopsy of these lesions revealed Lucio phenomenon. The patient worsened with mental confusion, psychomotor agitation and anisocoric pupils. In the 18th day of internation the patient died. Necropsy revealed virchowian infiltration plenty of bacilli in the skin and viscera as well as tuberculoid granuloma with acid-fast bacilli in the liver, spleen and bone marrow. These findings lead us to review the patient's classification from virchowian to borderline. In the lungs, leptomeninge, renal papile, prostate and thyroid it was found loose tuberculoid granuloma with a great amount of fungi surrounded by a gelly halo resembling Criptococcus neoformans. These findings and the onset of Lucio phenomenon are discussed in a patient that has been treated for 3 years and still having several virchowian lesions and a great amount of acid-fast bacilli.

  18. LiFePO4/polymer/natural graphite: low cost Li-ion batteries

    Zaghib, K.; Striebel, K.; Guerfi, A.; Shim, J.; Armand, M.; Gauthier, M

    2004-01-01

    The aging and performance of natural graphite/PEO-based gel electrolyte/LiFePO 4 cells are reported. The gel polymer electrolytes were produced by electron-beam irradiation and then soaked in a liquid electrolyte. The natural graphite anode in gel electrolyte containing LiBF4-EC/GBL exhibited high reversible capacity (345 mAh/g) and high coulombic efficiency (91%). The LiFePO 4 cathode in the same gel-polymer exhibited a reversible capacity of 160 mAh/g and 93% coulombic efficiency. Better performance was obtained at high-rate discharge with 6% carbon additive in the cathode, however the graphite anode performance suffers at high rate. The Li-ion gel polymer battery shows a capacity fade of 13% after 180 cycles and has poor performance at low temperature due to low diffusion of the lithium to the graphite in the GBL system. The LiFePO 4 /gel/Li system has an excellent rate capacity. LiFePO 4 cathode material is suitable for HEV application

  3. Regional sulfate-hematite-sulfide zoning in the auriferous Mariana anticline, Quadrilátero Ferrífero of Minas Gerais, Brazil

    Cabral, Alexandre Raphael; Koglin, Nikola; Strauss, Harald; Brätz, Helene; Kwitko-Ribeiro, Rogerio

    2013-10-01

    The distribution of mineral deposits, characterised as barite deposits, hematite-rich auriferous deposits and auriferous tourmaline-sulfide deposits, displays a regional sulfate-hematite-sulfide zoning along the thrust-delineated limbs of the Mariana anticline, in the south-eastern part of the Quadrilátero Ferrífero of Minas Gerais, Brazil. Cross-cut relationships of barite veins and sulfide lodes indicate that sulfidation occurred in a late-tectonic context, which is here attributed to the collapse of the ˜0.6-Ga Brasiliano thrust front. Reconnaissance S-isotopic data from barite and pyrite (Antônio Pereira barite deposit and its adjacent gold deposit, respectively), and arsenopyrite (Passagem de Mariana gold deposit), suggest a new interpretation for the hydrothermal fluid overprint in the Mariana anticline. The Antônio Pereira barite has Δ33S values that are near zero, constraining the sulfate source to rocks younger than 2.45 Ga. The barite-δ34S values are between +19.6 and +20.8 ‰. The Passagem arsenopyrite and tourmaline have Co/Ni ratios that define a positive linear trend with the Antônio Pereira pyrite. The latter has homogenous δ34S values, between +8.8 and +8.9 ‰, which are compatible with thermochemical reduction of aqueous sulfate with the S-isotopic composition of the Antônio Pereira barite.

  19. Development of an automated core model for nuclear reactors

    Mosteller, R.D.

    1998-01-01

    This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective of this project was to develop an automated package of computer codes that can model the steady-state behavior of nuclear-reactor cores of various designs. As an added benefit, data produced for steady-state analysis also can be used as input to the TRAC transient-analysis code for subsequent safety analysis of the reactor at any point in its operating lifetime. The basic capability to perform steady-state reactor-core analysis already existed in the combination of the HELIOS lattice-physics code and the NESTLE advanced nodal code. In this project, the automated package was completed by (1) obtaining cross-section libraries for HELIOS, (2) validating HELIOS by comparing its predictions to results from critical experiments and from the MCNP Monte Carlo code, (3) validating NESTLE by comparing its predictions to results from numerical benchmarks and to measured data from operating reactors, and (4) developing a linkage code to transform HELIOS output into NESTLE input

    Soil maps and models are fundamental for a correct and sustainable land management (Pereira et al., 2017). They are an important in the assessment of the territory and implementation of sustainable measures in urban areas, agriculture, forests, ecosystem services, among others. Soil maps represent an important basis for the evaluation and restoration of degraded areas, an important issue for our society, as consequence of climate change and the increasing pressure of humans on the ecosystems (Brevik et al. 2016; Depellegrin et al., 2016). The understanding of soil spatial variability and the phenomena that influence this dynamic is crucial to the implementation of sustainable practices that prevent degradation, and decrease the economic costs of soil restoration. In this context, soil maps and models are important to identify areas affected by degradation and optimize the resources available to restore them. Overall, soil data alone or integrated with data from other sciences, is an important part of sustainable land management. This information is extremely important land managers and decision maker's implements sustainable land management policies. The objective of this work is to present a review about the advantages of soil mapping and process modeling for sustainable land management.

  4. Spatio-temporal clustering of wildfires in Portugal

    Costa, R.; Pereira, M. G.; Caramelo, L.; Vega Orozco, C.; Kanevski, M.

    2012-04-01

    Several studies have shown that wildfires in Portugal presenthigh temporal as well as high spatial variability (Pereira et al., 2005, 2011). The identification and characterization of spatio-temporal clusters contributes to a comprehensivecharacterization of the fire regime and to improve the efficiency of fire prevention and combat activities. The main goalsin this studyare: (i) to detect the spatio-temporal clusters of burned area; and, (ii) to characterize these clusters along with the role of human and environmental factors. The data were supplied by the National Forest Authority(AFN, 2011) and comprises: (a)the Portuguese Rural Fire Database, PRFD, (Pereira et al., 2011) for the 1980-2007period; and, (b) the national mapping burned areas between 1990 and 2009. In this work, in order to complement the more common cluster analysis algorithms, an alternative approach based onscan statistics and on the permutation modelwas used. This statistical methodallows the detection of local excess events and to test if such an excess can reasonably have occurred by chance.Results obtained for different simulations performed for different spatial and temporal windows are presented, compared and interpreted.The influence of several fire factors such as (climate, vegetation type, etc.) is also assessed.

    2013-04-01

    Several studies demonstrate that wildfires in Portugal present high temporal and spatial variability as well as cluster behavior (Pereira et al., 2005, 2011). This study aims to contribute to the characterization of the fire regime in Portugal with the multivariate statistical analysis of the time series of number of fires and area burned in Portugal during the 1980 - 2009 period. The data used in the analysis is an extended version of the Rural Fire Portuguese Database (PRFD) (Pereira et al, 2011), provided by the National Forest Authority (Autoridade Florestal Nacional, AFN), the Portuguese Forest Service, which includes information for more than 500,000 fire records. There are many multiple advanced techniques for examining the relationships among multiple time series at the same time (e.g., canonical correlation analysis, principal components analysis, factor analysis, path analysis, multiple analyses of variance, clustering systems). This study compares and discusses the results obtained with these different techniques.

  6. Comparison of several databases of downward solar daily irradiation data at ocean surface with PIRATA measurements

    Trolliet, Mélodie; Wald, Lucien

    2017-04-01

    The solar radiation impinging at sea surface is an essential variable in climate system. There are several means to assess the daily irradiation at surface, such as pyranometers aboard ship or on buoys, meteorological re-analyses and satellite-derived databases. Among the latter, assessments made from the series of geostationary Meteosat satellites offer synoptic views of the tropical and equatorial Atlantic Ocean every 15 min with a spatial resolution of approximately 5 km. Such Meteosat-derived databases are fairly recent and the quality of the estimates of the daily irradiation must be established. Efforts have been made for the land masses and must be repeated for the Atlantic Ocean. The Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) network of moorings in the Tropical Atlantic Ocean is considered as a reference for oceanographic data. It consists in 17 long-term Autonomous Temperature Line Acquisition System (ATLAS) buoys equipped with sensors to measure near-surface meteorological and subsurface oceanic parameters, including downward solar irradiation. Corrected downward solar daily irradiation from PIRATA were downloaded from the NOAA web site and were compared to several databases: CAMS RAD, HelioClim-1, HelioClim-3 v4 and HelioClim-3 v5. CAMS-RAD, the CAMS radiation service, combines products of the Copernicus Atmosphere Monitoring Service (CAMS) on gaseous content and aerosols in the atmosphere together with cloud optical properties deduced every 15 min from Meteosat imagery to supply estimates of the solar irradiation. Part of this service is the McClear clear sky model that provides estimates of the solar irradiation that should be observed in cloud-free conditions. The second and third databases are HelioClim-1 and HelioClim-3 v4 that are derived from Meteosat images using the Heliosat-2 method and the ESRA clear sky model, based on the Linke turbidity factor. HelioClim-3 v5 is the fourth database and differs from v4 by the

    Ash is the footprint left by the fire. This residue is very important to landscape recover and is an important source of soil protection after the fire. Get immersed in fire ash world is the same thing of get dirty and do not be recognizable in a fire affected area. To measure ash in the field we have to be careful where to step, how to do the experimental design, collect samples and find with accuracy the places measured before. A good methodology is needed in design field experiments, collect ash samples and monitoring ash evolution (Cerdà and Doerr, 2008; Bodi et al., 2014; Pereira and Ubeda, 2010; Pereira et al. 2011; 2012, 2013, 2014, 2015). The objective of this work is to share with the Avatar world the methodologies used when wildgeographers get immersed in fire ash world, including: 1) Identify the best study area 2) Experimental design 3) Sample collection 4) Get dirty and have fun in the field 5) Laboratory, Statistical and spatial analysis Acknoledgements The author are thankful for the support of the projects POSTFIRE (Soil quality, erosion control and plant cover recovery under different post-fire management scenarios, CGL2013-47862-C2-1-R) funded by the Spanish Ministry of Economy and Competitiveness; GL2008-02879/BTE, LEDDRA 243857, RECARE (Preventing and Remediating Degradation of Soils in Europe Through Land Care, FP7-ENV-2013-TWO STAGE), funded by the European Commission; and for the COST action ES1306 (Connecteur: Connecting European Connectivity Research), FUEGORED (Spanish Network of Forest Fire Effects on Soils, http://grupo.us.es/fuegored/) and to Comissionat per a Universitats i Recerca del DIUE de la Generalitat de Catalunya.

    Kocher, C.W.; Quinn, T.J.; Krueger, D.A.

    1982-01-01

    The Dow TRIGA Mark I reactor is a one-hundred kilowatt nuclear reactor installed by General Atomics using the Torrey Pines reactor console, seventy-five used stainless-steel clad fuel elements and one new aluminium clad fuel element. The reactor is equipped with a forty-position rotating Lazy Susan in the reflector, a pneumatic transfer system with its terminal in the F-ring of the core, and a central thimble which can be used for irradiation of samples in the center of the core or which can be emptied of the shielding water to produce a beam of neutrons and gamma rays in the area atop the pool. Samples can also be irradiated in or near the core. There is no provision for pulsing this TRIGA reactor. The neutron activation analysis program uses the Dow TRIGA reactor as a source of thermal neutrons and a Kaman A711 generator as a source of 14-MeV neutrons. The associated counting equipment includes one Gel(Li) detector and two Nal(Tl) detectors, each using a 100-position sample changer and all interfaced to a Tracor-Northern TN-11 data acquisition and computing system, one Ge(Li) detector and its TN-11 system for the pneumatic transfer system and the beam tube experiments, and two NaKTl)detectors with a TN-4000 system used with the Kaman neutron generator. The activation analysis program gets samples from all parts of the manufacturing and research efforts at Dow: raw materials, intermediates, products, effluents, research samples, samples from customers who use Dow products, and environmental samples. This presentation is devoted to the progress made in the past year on the pneumatic transfer system and the renewed work on prompt gamma-ray spectroscopy including the extensive process of method validation

  11. Forming parts over small radii

    Hazra, S K; Hughes, D J; Pereira, M P; Rolfe, B F

    2016-01-01

    Stamping simulations usually make the plane stress simplifying assumption. However, this becomes less valid when material draws around features with radius to sheet thickness ratios less than 20. Pereira, Yan and Rolfe (Wear, Vol.265, p.1687 (2008)) predicted that out-of-plane stress equivalent to material yield can occur because a line contact forms briefly at the start of the draw process. The high transient stress can cause high rates of tool wear and may cause the ‘die impact line’ cosmetic defect. In this work, we present residual strain results of a channel section that was drawn over a small radius. Using the neutron source at the Institut Laue-Langevin, in-plane and out-of-plane strains were measured in the channel part to show some support for the conclusions of Pereira et. al. (paper)

    Pectiniunguis aequatorialis sp. nov. (Chilopoda: Geophilomorpha: Schendylidae) is described and illustrated on the basis of specimens collected in the Cayambe-Coca Ecological Reserve in the High Andes of Ecuador. The new species is characterized by having ventral pore-fields on the anterior region of the trunk only, a trait that is shared by a single Neotropical congener: Pectiniunguis ascendens Pereira, Minelli Barbieri, 1994 to which it is similar and is compared taxonomically. This is only the second report of a species of the genus Pectiniunguis Bollman, 1889 from mainland Ecuador. The other taxon is Pectiniunguis roigi Pereira, Foddai Minelli, 2001, so far only known from the type locality, Limoncocha (Sucumbíos Province), and herein reported for the first time from Parque Nacional Sumaco Napo-Galeras (Napo Province).

  5. Daddy, where did (PS)I come from?

    Baymann, F; Brugna, M; Mühlenhoff, U; Nitschke, W

    2001-10-30

    The reacton centre I (RCI)-type photosystems from plants, cyano-, helio- and green sulphur bacteria are compared and the essential properties of an archetypal RCI are deduced. Species containing RCI-type photosystems most probably cluster together on a common branch of the phylogenetic tree. The predicted branching order is green sulphur, helio- and cyanobacteria. Striking similarities between RCI- and RCII-type photosystems recently became apparent in the three-dimensional structures of photosystem I (PSI), PSII and RCII. The phylogenetic relationship between all presently known photosystems is analysed suggesting (a) RCI as the ancestral photosystem and (b) the descendence of PSII from RCI via gene duplication and gene splitting. An evolutionary model trying to rationalise available data is presented.

    Čerba, Štefan; Vrban, Branislav; Lüley, Jakub; Dařílek, Petr; Zajac, Radoslav; Nečas, Vladimír; Haščik, Ján

    2014-01-01

    Highlights: • Verification of the MCNPX, HELIOS and SCALE codes. • MOX and ceramic fuel assembly. • Gas-cooled fast reactor. • Burnup calculation. - Abstract: The gas-cooled fast reactor, which is one of the six GEN IV reactor concepts, is characterized by high operational temperatures and a hard neutron spectrum. The utilization of commonly used spectral codes, developed mainly for LWR reactors operated in the thermal/epithermal neutron spectrum, may be connected with systematic deviations since the main development effort of these codes has been focused on the thermal part of the neutron spectrum. To be able to carry out proper calculations for fast systems the used codes have to account for neutron resonances including the self-shielding effect. The presented study aims at verifying the spectral HELIOS, MCNPX and SCALE codes on the basis of depletion calculations of 2D MOX and ceramic fuel assemblies of the ALLEGRO gas-cooled fast reactor demonstrator in infinite lattice

    The eigenvalue calculation also includes quasi-static core depletion analyses. PARCS has implemented variety of features and has been qualified as a regulatory audit code in conjunction with other NRC thermal-hydraulic codes such as TRACE or RELAP5. In this study, as an adaptation effort for audit applications, PARCS is applied for an audit analysis of a reload core design. The lattice physics code HELIOS is used for cross section generation. PARCS-HELIOS code system has been established as a core analysis tool. Calculation results have been compared on a wide spectrum of calculations such as power distribution, critical soluble boron concentration, and rod worth. A reasonable agreement between the audit calculation and the reference results has been found.

  9. Helioseismology, Asteroseismology, and MHD Connections

    Gizon, Laurent; Leibacher, John

    2009-01-01

    This volume presents a timely snapshot of the state of helio- and asteroseismology in the era when the SOHO/MDI instrument is about to be replaced by SDO/HMI and the CoRoT space mission is yielding its first long-duration light curves of thousands of stars. The articles and topics in this book are inspired by two seminal conferences, HELAS II and SOHO19/GONG 2007, but contributions from other experts have been commissioned as well. For example, three key papers were invited to describe the current status of asteroseismology, global helioseismology, and local helioseismology. These papers provide a framework for the other contributions and together they form a complete description of our understanding of pressure waves in the Sun and other stars. This volume is aimed at solar physicists and astronomers specializing in helio- and asteroseismology.

  10. Message from the Director-General

    2005-01-01

    Dear Colleagues, It is with great sadness that I have to announce the accidental death on the 25 October of our colleague, José Pereira Lages, who worked for the company DBS. The team to which Mr Pereira Lages belonged was positioning an electrical switchgear cabinet, weighing 1200kg, on its support in the LHC tunnel. For reasons as yet unknown, the cabinet slipped on its support and fell on him. CERN's emergency services were on the scene immediately, but were unfortunately unable to help. The operation being undertaken was a common one, and Mr Pereira Lages had a reputation as one of the best forklift truck operators at CERN. Three enquiries were immediately opened: one led by CERN's security commission, a second by the Geneva works inspectorate and the third by the Geneva police. All work of a similar nature at CERN was stopped until further notice. To express sympathy with the victim's family and with his colleagues, transport and handling work was postponed until after a 24-hour period of respect....

    In post-fire environments ash has important benefits for soils, such as protection and source of nutrients, crucial for vegetation recuperation (Jordan et al., 2016; Pereira et al., 2015a; 2016a,b). The thickness and distribution of ash are fundamental aspects for soil protection (Cerdà and Doerr, 2008; Pereira et al., 2015b) and the severity at which was produced is important for the type and amount of elements that is released in soil solution (Bodi et al., 2014). Ash is very mobile material, and it is important were it will be deposited. Until the first rainfalls are is very mobile. After it, bind in the soil surface and is harder to erode. Mapping ash properties in the immediate period after fire is complex, since it is constantly moving (Pereira et al., 2015b). However, is an important task, since according the amount and type of ash produced we can identify the degree of soil protection and the nutrients that will be dissolved. The objective of this work is to apply to map ash properties (CaCO3, pH, and select extractable elements) using a principal component analysis (PCA) in the immediate period after the fire. Four days after the fire we established a grid in a 9x27 m area and took ash samples every 3 meters for a total of 40 sampling points (Pereira et al., 2017). The PCA identified 5 different factors. Factor 1 identified high loadings in electrical conductivity, calcium, and magnesium and negative with aluminum and iron, while Factor 3 had high positive loadings in total phosphorous and silica. Factor 3 showed high positive loadings in sodium and potassium, factor 4 high negative loadings in CaCO3 and pH, and factor 5 high loadings in sodium and potassium. The experimental variograms of the extracted factors showed that the Gaussian model was the most precise to model factor 1, the linear to model factor 2 and the wave hole effect to model factor 3, 4 and 5. The maps produced confirm the patternd observed in the experimental variograms. Factor 1 and 2

    1986-02-01

    The 238 U photofission and photoneutron cross sections, and the mean number -ν of prompt neutrons per fission, have been measured between 5 and 10 MeV. The experiment was carried out using bremsstrahlung from the electron linear accelerator HELIOS at Harwell. Neutrons from (γ,f) and (γ,n) reactions on 238 U were detected, and neutron multiplicity distributions recorded. Photoneutron events were separated from photofission events by means of their different multiplicities. (author)

    2000-01-01

    In this paper different pin-distributions of WWER-440 fuel assembly are examined. Assemblies contain 3 Gd-doped pins (Hungarian design), 6 Gd-doped pins near the assembly corners (Russian design) and differently profiled U5-enrichment in different pins. The main neutron physical characteristics of this assemblies - as the function of burnup - are calculated using HELIOS code. The calculated parameters of different assembly designs are analyzed from the standpoint of fuel cycle economy and refueling design practice. (Authors)

  4. Verification of a Subgroup Generation Method for Thorium Fuel Assemblies

    Sim, Ohsung; Kim, Myunghyun

    2013-01-01

    Resonance parameter consists of subgroup level and weight. The subgroup weight is obtained by solving the ultrafine slowing down equation and fixed source problem. That means this cross section library procedure considers conservation of the shielded cross section for pin-cell in order to obtain subgroup parameters. There are some isotopes to be concerned for research such as actinides and thorium. Minor actinides(MA) are existing with very small amount in a spent fuel, but effect is not negligible in a high burnup fuel assemblies. Some MAs have high fission cross sections under thermal neutron spectrum. Thorium isotopes was not investigated as much as uranium, but it has high potential for future application. In this study, a new cross section library to be replaced with HELIOS library was generated and compared for the assembly calculation, specially for assembly with thorium. An average capture cross section value at a certain fuel pin and multiplication factor of assembly were compared with nTRACER calculation with HELIOS library and Monte Carlo calculation of MCNP with ENDF-B/II. The accuracy of library data generated for thorium isotope in nTRACER calculation was tested for WASB model. There was a great improvement in K-eff and capture cross section for this assembly compared with old library, HELIOS library

  5. Study of a fuel assembly for the nuclear reactor of IV generation cooled with supercritical water

    Barragan M, A.; Martin del Campo M, C.; Francois L, J. L.; Espinosa P, G.

    2011-11-01

    In this work a neutron study is presented about a square assembly design of double line of fuel rods, with moderator box to the center of the arrangement, for a nuclear reactor cooled with supercritical water (SCWR). The SCWR reactor was chosen by the characteristics of its design, mainly because is based in light water reactors (PWR and BWR), and the operational experience that has of them allow to use models and similar programs to simulate the fuel and the nucleus of this type of reactors. To develop the necessary models and to carry out the design and analysis of the SCWR reactor, the neutron codes MCNPX and Helios were used. The reason of using both codes, is because the code MCNPX used thoroughly in the neutron simulation of these reactors, it has been our reference code to analyze the results obtained with the Helios code which results are more efficient because its calculation times are minors. In the nucleus design the same parameters for both codes were considered. The results show that the design with Helios is a viable option to simulate these reactors since their values of the neutrons multiplication factor are very similar to those obtained with MCNPX. On the other hand, it could be corroborated that the CASMO-4 code is inadequate to simulate the fuel to the temperature conditions and water pressure in the SCWR. (Author)

  6. Use of the smartt interferometer as an alignement tool for infrared laser systems

    Viswanathan, V.K.; Bolen, P.D.

    1979-01-01

    The ability to minimize the pointing and focusing errors at the focal plane is crucial in many applications involving infrared laser systems. This is particularly the case for systems involving multiple beams reaching the focal plane, as in the case of the LASL CO 2 laser fusion systems. For example, the LASL Helios CO 2 Laser Fusion System has eight 34-cm diameter beams each with an f number of approximately 2.4 coming to focus, the last element being an off-aperture parabola with a focal length of approximately 77.3 cm. The design tolerance for pointing accuracy is + 25 microns and for focusing acccuracy is +- 50 microns for the Helios system. The Smartt interferometer shows promise of not only evaluating the optical quality of the beam, but it can be used to align the beam to the tolerance levels stated above. This paper describes the procedure, as well as experimental results obtained, which show that pointing accuracies of +-12.5 microns and focusing accuracies of +- 25 microns are obtained at the focus of a CO 2 laser beam in a setup which duplicates the target regionn of the Helios CO 2 Laser Fusion System

  7. Ion acoustic waves in the solar wind

    Gurnett, D.A.; Frank, L.A.

    1978-01-01

    Plasma wave measurements on the Helios I and 2 spacecraft have revealed the occurrence of electric field turbulence in the solar wind at frequencies between the electron and ion plasma frequencies. Wavelength measurements with the Imp 6 spacecraft now provide strong evidence that these waves are short-wavelength ion acoustic waves which are Doppler-shifted upward in frequency by the motion of the solar wind. Comparison of the Helios results with measurements from the earth-orbiting Imp 6 and 8 spacecraft shows that the ion acoustic turbulence detected in interplanetary space has characteristics essentially identical to those of bursts of electrostatic turbulence generated by protons streaming into the solar wind from the earth's bow shock. In a few cases, enhanced ion acoustic wave intensities have been observed in direct association with abrupt increases in the anisotropy of the solar wind electron distribution. This relationship strongly suggests that the ion acoustic waves detected by Helios far from the earth are produced by an electron heat flux instability, as was suggested by Forslund. Possible related mechanisms which could explain the generation of ion acoustic waves by protons streaming into the solar wind from the earth's bow shock are also considered

  8. The application of the PARCS neutronics code to the Atucha-I and Atucha-II NPPs

    Ward, Andrew; Collins, Ben; Xu, Yunlin; Downar, Thomas [Purdue University, West Lafayette, IN (United States); Madariaga, Marcelo [Autoridad Nuclear Regulatoria, Buenos Aires (Argentina)

    2008-07-01

    In order to analyze Central Nuclear Atucha II (CNA-II) with coupled RELAP5/PARCS, extensive benchmarking of the neutronics codes HELIOS and PARCS was completed. This benchmarking was performed using a range of test problems designed in collaboration with NA-SA. HELIOS has been previously used to model Candu systems, but the results were validated for this case as well. The validation of both HELIOS and PARCS was performed primarily by comparisons to MCNP results for the same problems. Though originally designed to model light water systems, the capability of the PARCS was validated for predicting the performance of a Pressurized Heavy Water Reactor. The other noteworthy issue was the control rods. Because the insertion of the rods is oblique, a special routine was added to PARCS to treat this effect. Lattice level and Core level calculations were compared to the corresponding NA-SA codes WIMS and PUMA. In all cases there was good agreement in the results which provided confidence that the neutronics methods and the core neutronics modelling would not be a significant source of error in coupled RELAP5/PARCS calculations.

  9. Methods and Model Development for Coupled RELAP5/PARCS Analysis of the Atucha-II Nuclear Power Plant

    Andrew M. Ward

    2011-01-01

    Full Text Available In order to analyze the steady state and transient behavior of CNA-II, several tasks were required. Methods and models were developed in several areas. HELIOS lattice models were developed and benchmarked against WIMS/MCNP5 results generated by NA-SA. Cross-sections for the coupled RELAP5/PARCS calculation were extracted from HELIOS within the GenPMAXS framework. The validation of both HELIOS and PARCS was performed primarily by comparisons to WIMS/PUMA and MCNP for idealized models. Special methods were developed to model the control rods and boron injection systems of CNA-II. The insertion of the rods is oblique, and a special routine was added to PARCS to treat this effect. CFD results combined with specialized mapping routines were used to model the boron injection system. In all cases there was good agreement in the results which provided confidence in the neutronics methods and modeling. A coupled code benchmark between U of M and U of Pisa is ongoing and results are still preliminary. Under a LOCA transient, the best estimate behavior of the core appears to be acceptable.

  10. Impact of mineral fertilizers on common winter barley (Hordeum vulgare L. agrophytocenosis development

    2014-04-01

    Full Text Available In 2011 to 2013 a study was completed for the impact of varying rates of fertilizing onto the indices of productivity for barley agrophytocenosis of Helios and Commandor, in particular, such its components as a number of productive stems, number of seeds per ear, potential biological activity of ear and photosynthetic apparatus. It is found that the level of spring barley agrophytocenosis productivity is subject both to varietal peculiarities and the rate of mineral fertilizer application. When applying N 60P 60K 60 і N 90P 90K 90 the highest potential and biological productivity of Helios and Commandor was recorder as compared against the control. Impact of varying application rates for fertilizers onto the components of ear biological productivity has been scrutinized. The qualitative composition of ear is a clear expression of variety phenotype and identifies the level of biological yield for spring barley. Application of N 60 P 60 K 60 і N 90 P 90 K 90 mineral fertilizers fairly increased the average leaf surface, photosynthetic lead capacity of varieties in 2 to 2.5 times, as well as FAR efficiency coefficient in 1.5 to 2.0 times as against control that thus contributed to the development of highest biological yield of Helios variety phytomass at the level of 14.9 to 15.0, grain – 7.8 to 8.0 ton per ha and, respectively, 12.7 and 7.5 tons per ha for Comandor variety.

  11. A design approach for small vision-based autonomous vehicles

    Edwards, Barrett B.; Fife, Wade S.; Archibald, James K.; Lee, Dah-Jye; Wilde, Doran K.

    2006-10-01

    This paper describes the design of a small autonomous vehicle based on the Helios computing platform, a custom FPGA-based board capable of supporting on-board vision. Target applications for the Helios computing platform are those that require lightweight equipment and low power consumption. To demonstrate the capabilities of FPGAs in real-time control of autonomous vehicles, a 16 inch long R/C monster truck was outfitted with a Helios board. The platform provided by such a small vehicle is ideal for testing and development. The proof of concept application for this autonomous vehicle was a timed race through an environment with obstacles. Given the size restrictions of the vehicle and its operating environment, the only feasible on-board sensor is a small CMOS camera. The single video feed is therefore the only source of information from the surrounding environment. The image is then segmented and processed by custom logic in the FPGA that also controls direction and speed of the vehicle based on visual input.

  12. Transverse energy distribution, charged particle multiplicities and spectra in 16O-nucleus collisions

    Sunier, J.W.

    1987-01-01

    The HELIOS (High Energy Lepton and Ion Spectrometer) experiment, installed at the CERN Super Proton Synchrotron, proposes to examine in details the physical properties of a state of high energy created in nuclei by ultra-relativistic nucleus-nucleus collisions. It is generally believed that, at high densities or temperatures, a phase transition to a plasma of quark and gluons will occur. The dynamic of the expansion of such a plasma and its subsequent condensation into a hadron gas should markedly affect the composition and momentum distribution of the emerging particles and photons. The HELIOS experimental setup therefore combines 4π calorimetric coverage with measurements of inclusive particle spectra, two particle correlations, low and high mass lepton pairs and photons. The emphasis is placed on transverse energy flow (E/sub T/) measurements with good energy resolution, and the ability to trigger the acquisition of data in a variety of E/sub T/ ranges, thereby selecting the impact parameter or the violence of the collisions. This short note presents HELIOS results, for the most part still preliminary, on 16 O-nucleus collisions at the incident energies of 60 and 200 GeV per nucleon. The E/sub T/ distributions from Al, Ag and W targets are discussed and compared to the associated charged particle multiplicities from W. Charged particle and (converted) photon spectra measured with the external magnetic spectrometer are compared for 16 O + W and p + W collisions at 200 GeV per nucleon. 5 refs., 7 figs

    In order to analyze the steady state and transient behavior of CNA-II, several tasks were required. Methods and models were developed in several areas. HELIOS lattice models were developed and benchmarked against WIMS/MCNP5 results generated by NA-SA. Cross-sections for the coupled RELAP5/PARCS calculation were extracted from HELIOS within the Gen PMAXS framework. The validation of both HELIOS and PARCS was performed primarily by comparisons to WIMS/PUMA and MCNP for idealized models. Special methods were developed to model the control rods and boron injection systems of CNA-II. The insertion of the rods is oblique, and a special routine was added to PARCS to treat this effect.

  14. IMPROVED COMPUTATIONAL NEUTRONICS METHODS AND VALIDATION PROTOCOLS FOR THE ADVANCED TEST REACTOR

    David W. Nigg; Joseph W. Nielsen; Benjamin M. Chase; Ronnie K. Murray; Kevin A. Steuhm

    2012-04-01

    The Idaho National Laboratory (INL) is in the process of modernizing the various reactor physics modeling and simulation tools used to support operation and safety assurance of the Advanced Test Reactor (ATR). Key accomplishments so far have encompassed both computational as well as experimental work. A new suite of stochastic and deterministic transport theory based reactor physics codes and their supporting nuclear data libraries (HELIOS, KENO6/SCALE, NEWT/SCALE, ATTILA, and an extended implementation of MCNP5) has been installed at the INL. Corresponding models of the ATR and ATRC are now operational with all five codes, demonstrating the basic feasibility of the new code packages for their intended purpose. Of particular importance, a set of as-run core depletion HELIOS calculations for all ATR cycles since August 2009 was successfully completed during 2011. This demonstration supported a decision late in the year to proceed with the phased incorporation of the HELIOS methodology into the ATR fuel cycle management process beginning in 2012. On the experimental side of the project, new hardware was fabricated, measurement protocols were finalized, and the first four of six planned physics code validation experiments based on neutron activation spectrometry were conducted at the ATRC facility. Data analysis for the first three experiments, focused on characterization of the neutron spectrum in one of the ATR flux traps, has been completed. The six experiments will ultimately form the basis for a flexible, easily-repeatable ATR physics code validation protocol that is consistent with applicable ASTM standards.

    In this work a neutron study is presented about a square assembly design of double line of fuel rods, with moderator box to the center of the arrangement, for a nuclear reactor cooled with supercritical water (SCWR). The SCWR reactor was chosen by the characteristics of its design, mainly because is based in light water reactors (PWR and BWR), and the operational experience that has of them allow to use models and similar programs to simulate the fuel and the nucleus of this type of reactors. To develop the necessary models and to carry out the design and analysis of the SCWR reactor, the neutron codes MCNPX and Helios were used. The reason of using both codes, is because the code MCNPX used thoroughly in the neutron simulation of these reactors, it has been our reference code to analyze the results obtained with the Helios code which results are more efficient because its calculation times are minors. In the nucleus design the same parameters for both codes were considered. The results show that the design with Helios is a viable option to simulate these reactors since their values of the neutrons multiplication factor are very similar to those obtained with MCNPX. On the other hand, it could be corroborated that the CASMO-4 code is inadequate to simulate the fuel to the temperature conditions and water pressure in the SCWR. (Author)

  16. IGCP 637 Heritage Stone Designation: A UNESCO and IUGS project on natural stones

    Pereira, Dolores; Cooper, Barry; Schouenborg, Björn; Marker, Brian; Kramar, Sabina

    2017-04-01

    IGCP 637 was approved in 2015 to facilitate establishment of a new international geological standard for building and ornamental stones. Formal international recognition of those natural stone types that have achieved widespread utilization in human culture is now underway and the term "Global Heritage Stone Resource" (GHSR) has been proposed for this designation. Stones that have been used in heritage construction, sculptural masterpieces, as well as in utilitarian (yet culturally important) applications are obvious GHSR candidates. In co-ordination with these aims the project has an associated role to promote the adoption and use of the GHSR designation. Consequently an interim list of potential GHSRs is maintained and a register of GHSR approved stones is being created. IGCP 637 also enhances the capacity of the International Union of Geological Sciences (IUGS) in the realm of dimension stone and geological standards as it is the first IUGS involvement in this subject. As a consequence, the largest known international grouping of dimension stone professionals has been established. Within IGCP 637 a web page has been created at www.globalheritagestone.com, including information on the Working Group and also specific information on the evolution of the project. Several researchers were funded to attend the Heritage Stone working group activities, including researchers from Algeria, Malawi, India, Italy and Russia. We also have produced many publications, both as individual papers and special issues in journals included in the Journal Citation Reports. Monographs are being prepared at present. Hopefully, IGCP 637 will help to widen the circle of researchers interested in natural stones as part of our geoheritage.

    Ecosystem services (ES) potential assessment is crucial for a correct territorial planning at different scales of analysis (Depellegrin et al., 2016). In urban and peri-urban areas, sprawl, grazing and unsustainable agriculture practices contributed to land degradation and de decrease of the quality and quantity of the services provided by these areas (Eldridge and Delgado-Baquerizo, 2017; Favretto et al., 2017). In order to understand the spatial pattern of these impacts, mapping ES potential is key to understand the areas that need to be restored and protected for an unsustainable use (Brevik et al., 2016; Egarter-Vigl et al., 2017; Pereira et al., 2017). Hot-spot analysis is a good method to identify clusters of areas with high and low capacity for ES capacity. This analysis is very useful to detect homogeneous areas, where ES have high or low quality. The objective of this work is to apply a hot-spot analysis to detect areas with high/low capacity for Regulating, Provision, Cultural and Total ES in Vilnius region. ES potential was carried out based on the matrix developed by Burkhard et al. (2009), which ranks ES capacity from 0= no capacity to 5=very high relevant capacity to a different land use type. The results showed that regulating, providing and cultural and total ES have a significant dispersed (low-clustered) pattern: Regulating (Z-score=-19.28, pInternational Journal of Sustainable Development and World Ecology, 23, 441-455.

  18. The ash in forest fire affected soils control the soil losses. Part 2. Current and future research challenges

    Pereira, Paulo; Cerdà, Artemi

    2013-04-01

    Ash distribution on soil surface and impacts on soil properties received a great attention in recently (Pereira et al., 2010; Pereira et al., 2013). Ash it is a highly mobile material that can be easily transported wind, especially in severe wildland fires, where organic matter is reduced to dust, due the high temperatures of combustion. In the immediate period after the fire, ash cover rules soil erosion as previous researchers observed (Cerdà, 1998a; 1998b) and have strong influence on soil hydrological properties, such as water retention (Stoof et al. 2011 ) and wettability (Bodi et al., 2011). Ash it is also a valuable source of nutrients important for plant recuperation (Pereira et al., 2011; Pereira et al., 2012), but can act also as a source contamination, since are also rich in heavy metals (Pereira and Ubeda, 2010). Ash has different physical and chemical properties according the temperature of combustion, burned specie and time of exposition (Pereira et al., 2010). Thus this different properties will have different implications on soil properties including erosion that can increase due soil sealing (Onda et al. 2008) or decrease as consequence of raindrop impact reduction (Cerdà and Doerr, 2008). The current knowledge shows that ash has different impacts on soil properties and this depends not only from the type of ash produced, but of the soil properties (Woods and Balfour, 2010). After fire wind and water strong redistribute ash on soil surface, increasing the vulnerability of soil erosion in some areas, and reducing in others. Understand this mobility is fundamental have a better comprehension about the spatial and temporal effects of ash in soil erosion. Have a better knowledge about this mobility is a priority to future research. Other important aspects to have to be assessed in the future are how ash particulates percolate on soil and how ash chemical composition is important to induce soil aggregation and dispersion.

  19. On the use of the Serpent Monte Carlo code for few-group cross section generation

    Fridman, E.; Leppaenen, J.

    2011-01-01

    Research highlights: → B1 methodology was used for generation of leakage-corrected few-group cross sections in the Serpent Monte-Carlo code. → Few-group constants generated by Serpent were compared with those calculated by Helios deterministic lattice transport code. → 3D analysis of a PWR core was performed by a nodal diffusion code DYN3D employing two-group cross section sets generated by Serpent and Helios. → An excellent agreement in the results of 3D core calculations obtained with Helios and Serpent generated cross-section libraries was observed. - Abstract: Serpent is a recently developed 3D continuous-energy Monte Carlo (MC) reactor physics burnup calculation code. Serpent is specifically designed for lattice physics applications including generation of homogenized few-group constants for full-core core simulators. Currently in Serpent, the few-group constants are obtained from the infinite-lattice calculations with zero neutron current at the outer boundary. In this study, in order to account for the non-physical infinite-lattice approximation, B1 methodology, routinely used by deterministic lattice transport codes, was considered for generation of leakage-corrected few-group cross sections in the Serpent code. A preliminary assessment of the applicability of the B1 methodology for generation of few-group constants in the Serpent code was carried out according to the following steps. Initially, the two-group constants generated by Serpent were compared with those calculated by Helios deterministic lattice transport code. Then, a 3D analysis of a Pressurized Water Reactor (PWR) core was performed by the nodal diffusion code DYN3D employing two-group cross section sets generated by Serpent and Helios. At this stage thermal-hydraulic (T-H) feedback was neglected. The DYN3D results were compared with those obtained from the 3D full core Serpent MC calculations. Finally, the full core DYN3D calculations were repeated taking into account T-H feedback and

  20. The structure and origin of magnetic clouds in the solar wind

    V. Bothmer

    Full Text Available Plasma and magnetic field data from the Helios 1/2 spacecraft have been used to investigate the structure of magnetic clouds (MCs in the inner heliosphere. 46 MCs were identified in the Helios data for the period 1974–1981 between 0.3 and 1 AU. 85% of the MCs were associated with fast-forward interplanetary shock waves, supporting the close association between MCs and SMEs (solar mass ejections. Seven MCs were identified as direct consequences of Helios-directed SMEs, and the passage of MCs agreed with that of interplanetary plasma clouds (IPCs identified as white-light brightness enhancements in the Helios photometer data. The total (plasma and magnetic field pressure in MCs was higher and the plasma-β lower than in the surrounding solar wind. Minimum variance analysis (MVA showed that MCs can best be described as large-scale quasi-cylindrical magnetic flux tubes. The axes of the flux tubes usually had a small inclination to the ecliptic plane, with their azimuthal direction close to the east-west direction. The large-scale flux tube model for MCs was validated by the analysis of multi-spacecraft observations. MCs were observed over a range of up to ~60° in solar longitude in the ecliptic having the same magnetic configuration. The Helios observations further showed that over-expansion is a common feature of MCs. From a combined study of Helios, Voyager and IMP data we found that the radial diameter of MCs increases between 0.3 and 4.2 AU proportional to the distance, R, from the Sun as R0.8 (R in AU. The density decrease inside MCs was found to be proportional to R–2.4, thus being stronger compared to the average solar wind. Four different magnetic configurations, as expected from the flux-tube concept, for MCs have been observed in situ by the Helios probes. MCs with left- and right-handed magnetic helicity occurred with about equal frequencies during 1974–1981, but surprisingly, the majority (74% of the MCs had

  1. Fire vegetative ash and erosion in the Mediterranean areas. State of the art and future perspectives

    Pereira, Paulo; Cerdà, Artemi

    2013-04-01

    Fire is a global phenomenon with important ecological impacts. Among all ecosystems, the Mediterranean is frequently visited by severe wildfires with serious impacts on soil properties and increase soil vulnerability to erosion due vegetation removal. After the fire the ash distributed in soil surface can mitigate soil exposition to erosion and rain splash (Cerda and Doerr, 2008), however, this depends on the fire severity that have implications on the type of ash produced (Pereira et al., 2010). High fire severities produced thinner ash that it is easily transported by wind, contrary to low severity wildfires where combustion is not so intense and the mass loss is less, providing a better soil protection in the immediate period after the fire. Soil protection after the fire highly depends on fire severity (Pereira et al. 2013a; Pereira et al. 2013b). Ash it is a highly mobile material, thus this protection can change in space and time, providing a better cover in some areas and worst in others. In the period immediate after the fire, ash can change soil hydrological properties, increasing water retention and reducing sediment transport in relation to bare soil areas (Cerda and Doerr, 2008), but also clog soil pores, seal the soil and increase erosion (Onda et al., 2008). In fact results are controversial and the impacts of vegetative ash in soil erosion may rely on the proprieties of ash produced, that can be extremely variable, even in small distances (Pereira and Úbeda, 2010), due the different conditions of combustions. Ash produced at low severity temperatures can be highly hydrophilic (Bodi et al., 2011) and induce soil hydrophobicity (Bodi et al., 2012). Other mechanisms as the direct impact of fire in soil, can induce soil water repellency, and do not have any interference of vegetative ash. This fire can induce direct (e.g temperature) and indirect (e.g. ash properties) on soil wettability, with obvious implications on spatio-temporal pattern of soil

En todos los corredores viales por los cuales se transportan mercancías peligrosas existen zonas críticas de alta accidentalidad.

  3. Soil mapping and process modeling for sustainable land use management: a brief historical review

    Brevik, Eric C.; Pereira, Paulo; Muñoz-Rojas, Miriam; Miller, Bradley A.; Cerdà, Artemi; Parras-Alcántara, Luis; Lozano-García, Beatriz

    2017-04-01

    Basic soil management goes back to the earliest days of agricultural practices, approximately 9,000 BCE. Through time humans developed soil management techniques of ever increasing complexity, including plows, contour tillage, terracing, and irrigation. Spatial soil patterns were being recognized as early as 3,000 BCE, but the first soil maps didn't appear until the 1700s and the first soil models finally arrived in the 1880s (Brevik et al., in press). The beginning of the 20th century saw an increase in standardization in many soil science methods and wide-spread soil mapping in many parts of the world, particularly in developed countries. However, the classification systems used, mapping scale, and national coverage varied considerably from country to country. Major advances were made in pedologic modeling starting in the 1940s, and in erosion modeling starting in the 1950s. In the 1970s and 1980s advances in computing power, remote and proximal sensing, geographic information systems (GIS), global positioning systems (GPS), and statistics and spatial statistics among other numerical techniques significantly enhanced our ability to map and model soils (Brevik et al., 2016). These types of advances positioned soil science to make meaningful contributions to sustainable land use management as we moved into the 21st century.

  10. Population structure and condition factor of Pseudotothyris obtusa (hypoptopomatinae from three coastal streams in southern Brazil

    Denise de Freitas Takeuti

    1999-01-01

    Full Text Available Population structure features and condition factor of Pseudotothyris obtusa were compared between three coastal streams in southern Brazil. Fishes were monthly collected through electric fishing and measured in the total length. Fifteen fishes from each stream were dissected to identify their sex. The structure in size, sex ratio and young/adults ratio of populations were analysed and the length-weight relationship was obtained. The condition factor (K1 and the relative condition factor (Kn were calculated for each stream. Fishes were grouped in 11 lenght classes of 3mm. The intermediate and bigger size classes were preponderant in the "Mergulhão" and "Colônia Pereira" streams, and the smaller and intermediate ones in the "Ribeirão" stream. Females prevailed in bigger size classes, reached bigger lengths than males, and were preponderant in all streams. The condition factors (K1 and Kn were different in all streams, indicating better condition and higher weight values in fishes from the "Mergulhão" and "Colônia Pereira" streams.Características da estrutura da população e o fator de condição de Pseudotothyris obtusa foram comparados em três rios costeiros na região sul do Brasil.

    O mercado de carnes no Brasil e no mundo está cada vez mais competitivo e complexo. Essa complexidade é resultante sobretudo do ciclo de vida e do grau de perecibilidade do produto, das exigencias de rigorosos controles sanitários e da crescente demanda por diversificação e agregação de valor, mesmo no caso de um mercado cujo principal produto é, em essencia, uma commodity (PEREIRA, 2003).

  17. Solar radiation estimation based on the insolation

    Assis, F.N. de; Steinmetz, S.; Martins, S.R.; Mendez, M.E.G.

    1998-01-01

    A series of daily global solar radiation data measured by an Eppley pyranometer was used to test PEREIRA and VILLA NOVA’s (1997) model to estimate the potential of radiation based on the instantaneous values measured at solar noon. The model also allows to estimate the parameters of PRESCOTT’s equation (1940) assuming a = 0,29 cosj. The results demonstrated the model’s validity for the studied conditions. Simultaneously, the hypothesis of generalizing the use of the radiation estimative formulas based on insolation, and using K = Ko (0,29 cosj + 0,50 n/N), was analysed and confirmed [pt

  19. Isotope and hydrochemical models for evaluation the water loss by evaporation and groundwater flow of dams

    Santiago, M.F.; Reboucas, A.C.; Frischkorn, H.

    1986-01-01

    Two different approaches are made: an isotope model, based on the observation of the 180/160 ratio of the water, and an hydrochemical model, using the Cl - concentration, are described and applied to determine the evaporation and groundwater flow rates from or to dams. During a period of three years the dams Pereira de Miranda and Caxitore in Pentecostes - Ceara-Brazil (80 Km west of Fortaleza), located in the Precambrian cristalline rock area, were studies. The results show that the models have a good applicability, to estimate the average daily depth of evaporation from free-water surfaces, from nearby porous media or the groundwater inflow or outflow.

    Full Text Available The paper presents the main arguments of Bresser Pereira's Globalization and Competition. Development strategies based on the 'conventional orthodoxy' are shown to carry serious drawbacks ("Dutch disease", pernicious effects of external saving, currency overvaluation, while a 'new developmentalism' is promoted, in spite of the widespread belief that the nation-states have been dispossessed of their room for manoeuvre because of the globalization process. The "new developmentalism" is based on domestic finance, balanced public budgets, moderate interest rates and competitiveness policies aimed at neutralizing the tendency to exchange rate overappreciation. The paper also points out a few theoretical questions the book raises.

  4. Assessing the outstanding 2003 fire events in Portugal with a Regional Climate Model

    Trigo, Ricardo; Jerez, Sonia; Camara, Carlos; Montávez, Juan Pedro

    2013-04-01

    The heatwave that struck western Iberia in the early days of August 2003 was characterized by record high values of both maximum (47.3°C) and minimum (30.6°c) temperatures in Portugal, associated with extremely low humidity levels and relatively intense wind speed (Trigo et al., 2006). These conditions triggered the most devastating sequence of large fires ever registered in Portugal. The estimated total burnt area was about 450.000 ha, including 280.000 ha of forest (Pereira et al., 2011). The outstanding total burnt area value corresponds to roughly 5% of the Portuguese territory, and represents approximately twice the previous maximum observed in 1998 (~220.000 ha), and about four times the long-term average observed between 1980 and 2004. Here we characterise this unusual episode using meteorological fields obtained from both observations and a regional climate model. In this work we use the longest (49-years) high-resolution regional climate simulation available driven by reanalysis data spanning from 1959 to 2007 and covering the entire Iberian Peninsula. This long run was obtained using the MM5 model with a spatial resolution of 10 km. Using this high spatial and temporal resolution we have computed the Canadian Fire Weather Index (FWI) System to produce hourly values of fire risk. The FWI System consists of six components that account for the effects of fuel moisture and wind on fire behaviour (van Wagner, 1987). We show the temporal evolution of high resolution patterns for several fire related variables during the most important days for triggering new fires (the first week of August 2003). Besides the absolute value of Tmax, Tmin, wind (speed and direction), relative humidity and FWI we also evaluate the corresponding anomalies of these fields, obtained after removing the long-term smoothed daily climatology.

  5. Equivalent and Alternative Forms for BF Gravity with Immirzi Parameter

    Merced Montesinos

    2011-11-01

    Full Text Available A detailed analysis of the BF formulation for general relativity given by Capovilla, Montesinos, Prieto, and Rojas is performed. The action principle of this formulation is written in an equivalent form by doing a transformation of the fields of which the action depends functionally on. The transformed action principle involves two BF terms and the two Lorentz invariants that appear in the original action principle generically. As an application of this formalism, the action principle used by Engle, Pereira, and Rovelli in their spin foam model for gravity is recovered and the coupling of the cosmological constant in such a formulation is obtained.

    1998-06-01

    This study was undertaken to clarify several aspects of morphological and taxonomic characters of Physaloptera bispiculata Vaz and Pereira, 1935, a parasite of the water rat, Nectomys squamipes. The cephalic structures (including lips, papillae, teeth, amphids, and porous areas) and details of the posterior end of male and female adult worms were examined by scanning electron microscopy, leading to the addition of new taxonomic characters for this species. We consider P. bispiculata a valid species, based on a comparative analysis of the specific characters for P. bispiculata and P. getula Seurat, 1917, including the morphology and morphometry of body structures as well as number and disposition of caudal papillae of the males.

    Several existing correlations between radiation monthly mean ratios of global to extraterrestrial and diffuse to global were tried for four Indian stations and found inadequate. New correlations were established for these stations and it was shown that these correlations are highly climate dependent. Classical equation of Liu and Jordon was tried to find hourly diffuse and global radiation from daily sums of diffuse and global radiation respectively. It was suitably modified to suit the Indian data. Equations developed by Collares-Pereira and Rabl have shown excellent agreement with the observed values

  13. Measurement of the transverse energy spectrum in proton-nucleon collisions

    Bettoni, D.

    1988-01-01

    The author describes a measurement of the transverse energy spectrum in proton-nucleon interactions carried out at the CERN SPS using the HELIOS spectrometer. The measurement is of particular interest in that it is performed in a rapidity region away from central rapidity, where experimental data is scarce. In this rapidity region very interesting physics is anticipated and the measurement of the proton-nucleon collisions is essential as a basis to understand the more complicated proton-nucleus and nucleus-nucleus interactions. Both these topics are part of the experimental program of HELIOS. The measurement was done using a deuterium target enclosed in an iron tube. The contribution to the transverse energy spectrum from the p-Fe events is discriminated against by reconstructing the primary interaction vertex using drift chamber information. The measured spectrum is corrected via Monte Carlo to deconvolute the effect of reinteractions. High spatial resolution and multi-track resolving power are achieved with the use of a cool gas, such that the electron characteristic energy is close to the thermal limit: this implies a small diffusion coefficient and a consequently good positional accuracy. Of vital importance are the low value of the drift velocity, the fast, differentiating electronics and a careful shaping of the electric field configuration to improve the isochrony of the drift collection. The author reports on the design and tests of drift chamber prototypes built along the above lines, with which a spatial accuracy of 0.06 mm and a double track resolution of 0.6 mm were measured. He also describes the final drift chamber system and its operation in HELIOS

  14. Very local interstellar spectra for galactic electrons, protons and helium

    Potgieter, Marius S., E-mail: Marius.Potgieter@nwu.ac.za [Centre for Space Research, North-West University (South Africa)

    2014-07-01

    The local interstellar spectra (LIS) for cosmic rays at energies below ∼30 GeV/nuc are increasingly obscured from view at Earth by solar modulation, the lower the energy becomes. These charged particles encounter significant changes in the heliosphere, over an 11-year cycle, which include processes such as convection, diffusion, adiabatic energy losses and gradient, curvature and current sheet drifts. Particle drifts cause charge-sign-dependent modulation and a 22-year cycle, adding complexity to determining the respective very LIS from observations only at Earth. However, with measurements now made by the Voyager 1 spacecraft in the vicinity of the helio pause, it is possible to determine a very LIS for galactic electrons between ∼5 and ∼120 MeV. At these low energies, also galactic protons observed in the outer heliosphere had been completely obscured by the so-called anomalous component which is accelerated inside the helio sheath. Since August 2012, these anomalous cosmic rays are substantially depleted at Voyager 1 so that for cosmic ray ions, it is now possible to obtain a lower limit to their very LIS. Combining numerical modelling of solar modulation with the accurate measurements by the PAMELA mission and with Voyager observations, the lower limit of the very LIS for electrons, protons and helium and other ions can be determined from ∼5 MeV and above. These spectra are called helio pause spectra which is considered to be the lowest possible very LIS. Also, from an astrophysics point of view, the determination of what can be called a very LIS, not just an averaged galactic spectrum, is encouraging. The mentioned aspects are discussed, focusing on a comparison of recent heliospheric observations and corresponding solar modulation modelling. (author)

  15. T cell responses in senior patients with community-acquired pneumonia related to disease severity.

    Bian, Lu-Qin; Bi, Ying; Zhou, Shao-Wei; Chen, Zi-Dan; Wen, Jun; Shi, Jin; Mao, Ling; Wang, Ling

    Senior individuals older than 65 years of age are at a disproportionally higher risk of developing pneumonia. Impaired capacity to defend against airway infections may be one of the reasons. It is generally believed that weaker regulatory T cell responses may be beneficial to host defense against pathogens. In senior patients with community-acquired bacterial pneumonia, we investigated the frequencies and functions of regulatory T cells. Interestingly, we found that compared to age- and sex-matched healthy controls, senior pneumonia patients presented lower frequencies of Foxp3-expressing and Helios-expressing CD4 + T cells. The quantity of Foxp3 and Helios being expressed, measured by their mRNA transcription levels, was also lower in CD4 + T cells from pneumonia patients. Furthermore, following TCR and TGF-β stimulation, pneumonia patients presented impaired capacity to upregulate Foxp3 and Helios. Functional analyses revealed that CD4 + T cells from pneumonia patients secreted lower amounts of IL-10 and TGF-β, two cytokines critical to regulatory T cell-mediated suppression. Also, the expression of granzyme B and perforin, which were cytolytic molecules potentially utilized by regulatory T cells to mediate the elimination of antigen-presenting cells and effector T cells, were reduced in CD4 + CD25 + T cells from senior pneumonia patients. In addition, the CD4 + CD25 + T cells from senior pneumonia patients presented reduced capacity to suppress effector CD4 + and CD8 + T cell proliferation. Moreover, the value of pneumonia severity index was inversely correlated with several parameters of regulatory T cell function. Together, our results demonstrated that senior pneumonia patients presented a counterintuitive impairment in regulatory T cell responses that was associated with worse prognosis.

  17. The nuclear option

    Herken, G.

    1992-01-01

    A development history and current status evaluation are presented for nuclear-thermal rocket propulsion systems applicable to interplanetary flight. While the most advanced current chemical rocket engines, such as the SSMEs of the Space Shuttle, produce specific impulses of the order of 450 secs, a nuclear-thermal rocket engine tested at Los Alamos in 1969 generated 845 secs; such specific impulse improvements could represent weeks or months of interplanetary travel time. Attention is given to the achievements of the historical Nuclear Engine for Rocket Vehicle Application, Helios, and Orion design programs, as well as to the current Vehicle for Interplanetary Space Transportation Applications, which is fusion-based

  18. A review on the heterogeneous thorium fuel concept for PWR applications

    Joo, H. K.; Noh, J. M.; Yoo, J. W.; Kim, K. H.

    2001-08-01

    Seed-blanket unit (SBU) and whole assembly seed and blanket (WASB) are being investigated for the PWR application as well as homogeneous thorium fuel under the US NERI program. For the verification of HELIOS capability for thorium analysis, the characteristics of heterogeneous thorium fuels was evaluated by HELIOS color-set calculation and compared with the calculation results of the US NERI. The infinite multiplication factors from HELIOS calculation are in good agreement with CASMO-4 except for SBU which uses metallic fuel for seed material. The maximum relative difference in power distribution is occurred in WASB case, and is about 5% compared to MCNP. The isotopic concentrations for Am-241, Am-243, and Cm-244 of HELIOS agree well with CASMO-4's, but show a significant discrepancy from MOCUP mainly caused by the old data of cross section and decay constants in ORIGEN. The nonproliferation characteristic of thorium-based fuel such as critical mass, spontaneous fission rate, decay heat generation rate are superior to the conventional uranium fuel. Even though the diversion of U-233 produced in blanket is a technically difficult, the enrichment of uranium isotopes including U-233 is slightly over the limit for safeguard aspects. The urnaium contents in thorium fuel is need to be adjusted in order to meet the safeguard limit. A preliminary assessment of fuel economics was performed based on the uranium utilization and SWU utilization. The natural uranium utilization factors of heterogeneous thorium-based fuel increased by 10δ18%, but the SWU utilization factor decreased by 6-δ11% compared to uranium fuel. The cost of uranium purchase of 50USI/KgU and SWU cost of 110USI/SWU-Kg, recommended by OECD/NEA, gives a comparable economics of thorium-based fuel to uraium fuel. The detailed fuel cycle analysis will take account of the other factors like the variation of uranium purchase cost and SWU cost, fabrication cost of thorium fuel, thorium purchase cost, the capcity

    1981-01-01

    The Los Alamos Scientific Laboratory Inertial Confinement Fusion Program is reviewed. Experiments using the Helios CO 2 laser system delivering up to 6kJ on target are described. Because breakeven energy estimates for laser drivers of 1 μm and above have risen and there is a need for CO 2 experiments in the tens-of-kJ regime as soon as practical, a first phase of Antares construction is now directed toward completion of two of the six original modules in 1983. These modules are designed to deliver 40kJ of CO 2 laser light on target. (author)

    The Supercritical Water Cooled Reactor (SCWR) is one of the most promising and innovative designs selected by the Generation IV International Forum. One of the concepts being studied is the High Performance Light Water Reactor (HPLWR), which is the European version of the SCWR. In this paper we present the numerical analysis of the behavior of a HPLWR with temperature feedback effects. The neutronic process, the heat transfer in the fuel rod and the thermalhydraulics in the core of the HPLWR were considered in this study. The neutronic calculations were performed with HELIOS-2 and the obtained results were used to evaluate the reactivity due to fuel temperature and supercritical water density. (author)

  8. Response of Earth and Venus ionospheres to corotating solar wind stream of 3 July 1979

    Taylor, H.A. Jr.

    1985-01-01

    Corotating solar wind streams emanating from stable coronal structures provide an unique opportunity to compare the response of planetary ionospheres to the energy conveyed in the streams. For recurrent solar conditions the 'signal' propagating outward along spiral paths in interplanetary space can at times exhibit rather similar content at quite different downstream locations in the ecliptic plane. Using solar wind measurements from plasma detectors on ISEE-3, Pioneer Venus Orbiter (PVO) and Helios-A, as well as in-situ ion composition measurements from Bennett Ion Mass Spectrometers on the Atmosphere Explorer-E and PVO spacecraft, corotating stream interactions are examined at Earth and Venus.

  9. Polarization state of hydromagnetic fluctuations in the solar wind

    Bavassano, B.; Dobrowolny, M.; Mariani, F.; Ness, N.F.

    1981-01-01

    From presently available observations one can infer that the Alfvenic turbulence measured in the solar wind, predominantly on trailing edges of high-speed streams, is a mixture of modes with two different polarizations, namely. Alfvenic modes and modes which are the incompressible limit of slow magnetosonic waves. Using Helios 2 magnetic data and a variance analysis, we have separated parallel (to the mean field) and perpendicular components of the fluctuations and studied the possible correlation between such components which would be predicted as a consequence of the imcompressible character of the turbulence. Correlations between eigenvalues of the variance matrix are also investigated and discussed

    Heavy ion collisions produce dense and hot nuclear matter. Dileptons give information about this hot and dense phase. The dileptons are produced by vector mesons. Theoretical calculation of dilepton production in the DLS (Berkeley), the HADES (GSI) experiments and the CERES, HELIOS and NA60 data from CERN give information about possible modifications of the vector meson properties in hot and dense nuclear matter. Here the description in relativistic quantum molecular dynamics of heavy ion collisions and dilepton production are presented and compared with data.

  20. Radioisotope-powered photovoltaic generator

    McKlveen, J.W.; Uselman, J.

    1979-01-01

    Disposing of radioactive wastes from nuclear power plants has become one of the most important issues facing the nuclear industry. In a new concept, called a radioisotope photovoltaic generator, a portion of this waste would be used in conjunction with a scintillation material to produce light, with subsequent conversion into electricity via photovoltaic cells. Three types of scintillators and two types of silicon cells were tested in six combinations using 32 P as the radioisotope. The highest system efficiency, determined to be 0.5% when the light intensity was normalized to 100 mW/cm 2 , was obtained using a CsI crystal scintillator and a Helios photovoltaic cell
