Dentro de este grupo de sustancias, dos de las más importantes por su incidencia en el rendimiento y calidad de las cosechas son las Giberelinas (GAs y las Auxinas. Diversas técnicas cromatográficas como la Cromatografía de Capa Fina (CCF, la Cromatografía de Gases (CG y la Cromatografía Líquida de Alta Resolución (CLAR han sido utilizadas para la determinación de fitohormonas. La CCF resulta ser una opción más sencilla y económica, útil para el seguimiento de rutina de la fermentación. Se lograron establecer dos métodos analíticos para la determinación cualitativa de Giberelinas y Auxinas en caldos de fermentación como métodos alternativos más sencillos y menos costosos que la CLAR. Para la CCF de GAs se utilizó una placa de Sílica gel G y como sistema de disolventes cloroformo/acetato de etilo/ácido acético glacial (5:4:1. El revelador consistió en una mezcla de ácido sulfúrico-etanol (95:5. Para las Auxinas se utilizó una placa de Silica gel HF254 y como sistema de disolventes benceno/acetato de etilo/ácido acético (70:25:5. Se utilizó como revelador la disolución de Salkowski. Los métodos de análisis por CCF, establecidos tanto para las GAs como para las Auxinas, permitieron definir que la extracción líquido-líquido permite purificar de cierta manera los caldos de fermentación y verificar la presencia de estos compuestos y otros metabolitos, en los caldos fermentados y en sus extractos.

    Full Text Available Se muestran los resultados preliminares obtenidos de la detección de extractos orgánicos de metabolitos antifúngicos de Pseudomonas aeruginosa cepa PSS por cromatografía de capa fina (CCF. Las extracciones fueron llevadas a cabo con acetato de etilo y la fase orgánica se analizó por TLC empleando el sistema de solvente cloroformo: acetona (3:1 como fase móvil. Para discernir el metabolito con actividad antifúngica se realizó un ensayo de Bioautografía utilizando el hongo Aspergillus flavus. Como resultado, se observó una mancha con Rf entre 0.70-0.80 detectada a luz ultravioleta (255 nm y revelada con vainillina que presenta actividad antifúngica, por lo que es posible de una manera preliminar detectar los metabolitos antifúngicos mediante la combinación de estos dos métodos.

  10. 1996 ICF program overview

    International Nuclear Information System (INIS)

    The continuing objective of the Inertial Confinement Fusion (ICF) Program is the demonstration of thermonuclear fusion ignition and energy gain in the laboratory. The underlying theme of all ICF activities as a science research and development program is the Department of Energy's (DOE's) Defense Programs (DP) science-based Stockpile Stewardship and Management (SSM) Program. The extension of current program research capabilities in the National Ignition Facility (NIF) is necessary for the ICF Program to satisfy its stewardship responsibilities. ICF resources (people and facilities) are increasingly being redirected in support of the performance, schedule, and cost goals of the NIF. One of the more important aspects of ICF research is the national nature of the program. Lawrence Livermore National Laboratory's (LLNL's) ICF Program falls within DOE's national ICF Program, which includes the Nova and Beamlet laser facilities at LLNL and the OMEGA, Nike, and Trident laser facilities at the University of Rochester (Laboratory for Laser Energetics, UR/LLE), the Naval Research Laboratory (NRL), and Los Alamos National Laboratory (LANL), respectively. The Particle Beam Fusion Accelerator (PBFA) and Saturn pulsed-power facilities are at Sandia National Laboratories (SNL). General Atomics, Inc. (GA) develops and provides many of the targets for the above experimental facilities. LLNL's ICF Program supports activities in two major interrelated areas: (1) target physics and technology (experimental, theoretical, and computational research); and (2) laser science and optics technology development. Experiments on LLNL's Nova laser primarily support ignition and weapons physics research. Experiments on LLNL's Beamlet laser support laser science and optics technology development. In addition, ICF sciences and technologies, developed as part of the DP mission goals, continue to support additional DOE objectives. These objectives are (1) to achieve diversity in energy sources

    The continuing objective of Lawrence Livermore National Laboratory's (LLNL's) Inertial Confinement Fusion (ICF) Program is the demonstration of thermonuclear fusion ignition and energy gain in the laboratory and to support the nuclear weapons program in its use of ICF facilities. The underlying theme of all ICF activities as a science research and development program is the Department of Energy's (DOE's) Defense Programs (DP) science-based Stockpile Stewardship Program (SSP). The mission of the US Inertial Fusion Program is twofold: (1) to address high-energy-density physics issues for the SSP and (2) to develop a laboratory microfusion capability for defense and energy applications. In pursuit of this mission, the ICF Program has developed a state-of-the-art capability to investigate high-energy-density physics in the laboratory. The near-term goals pursued by the ICF Program in support of its mission are demonstrating fusion ignition in the laboratory and expanding the Program's capabilities in high-energy-density science. The National Ignition Facility (NIF) project is a cornerstone of this effort.

    This paper reflects on the use of ICF in Ireland, taking as a case study the experience of the first National Disability Survey (NDS). There were four clear effects in Ireland of using ICF as a framework for the NDS: a) that a broader range of people with disabilities was encompassed; b) that the environmental factors included from the ICF were comprehensive and policy relevant; c) that both barriers and facilitators were incorporated into the model; and d) that a focus on research ethics was encouraged. Some general conclusions regarding the benefits and limitations of ICF based on this experience are also drawn.

  16. Insect capa neuropeptides impact desiccation and cold tolerance.

    The success of insects is linked to their impressive tolerance to environmental stress, but little is known about how such responses are mediated by the neuroendocrine system. Here we show that the capability (capa) neuropeptide gene is a desiccation- and cold stress-responsive gene in diverse dipteran species. Using targeted in vivo gene silencing, physiological manipulations, stress-tolerance assays, and rationally designed neuropeptide analogs, we demonstrate that the Drosophila melanogaster capa neuropeptide gene and its encoded peptides alter desiccation and cold tolerance. Knockdown of the capa gene increases desiccation tolerance but lengthens chill coma recovery time, and injection of capa peptide analogs can reverse both phenotypes. Immunohistochemical staining suggests that capa accumulates in the capa-expressing Va neurons during desiccation and nonlethal cold stress but is not released until recovery from each stress. Our results also suggest that regulation of cellular ion and water homeostasis mediated by capa peptide signaling in the insect Malpighian (renal) tubules is a key physiological mechanism during recovery from desiccation and cold stress. This work augments our understanding of how stress tolerance is mediated by neuroendocrine signaling and illustrates the use of rationally designed peptide analogs as agents for disrupting protective stress tolerance.

  17. Hydrodynamick instabilities on ICF capsules

    International Nuclear Information System (INIS)

    This article summarizes our current understanding of hydrodynamic instabilities as relevant to ICF. First we discuss classical, single mode Rayleigh-Taylor instability, and nonlinear effects in the evolution of a single mode. Then we discuss multimode systems, considering: (1) the onset of nonlinearity; (2) a second order mode coupling theory for weakly nonlinear effects, and (3) the fully nonlinear regime. Two stabilization mechanisms relevant to ICF are described next: gradient scale length and convective stabilization. Then we describe a model which is meant to estimate the weakly nonlinear evolution of multi-mode systems as relevant to ICF, given the short-wavelength stabilization. Finally, we discuss the relevant code simulation capability, and experiments. At this time we are quite optimistic about our ability to estimate instability growth on ICF capsules, but further experiments and simulations are needed to verify the modeling. 52 refs

    Full Text Available The preparation of carbon nitride thin films by ablation of different target compounds (graphite, guanazole in a reactive atmosphere of ammonia with an ArF excimer laser (193 nm is reported. The films were deposited on different substrates (silicon wafers and aluminium plates and were analysed with different techniques such as profilometry, Fourier transform infrared (FTIR and energy dispersive X-ray spectroscopy (EDX. For both targets, a comparative study of the influence of the ammonia total pressure on the growth rate, composition and properties of the obtained material has been done. A gradual nitrogen incorporation in the films with increasing ammonia pressure and also the presence of nitrogen bonded to carbon in different configurations (simple, double and/or triple bonds was observed. The use of guanazole targets leads to higher efficiency in the nitrogen incorporation and in the formation of simple C-N bonds.

  19. Fundamentals of ICF Hohlraums

    Rosen, M D

    2005-09-30

    On the Nova Laser at LLNL, we demonstrated many of the key elements required for assuring that the next laser, the National Ignition Facility (NIF) will drive an Inertial Confinement Fusion (ICF) target to ignition. The indirect drive (sometimes referred to as ''radiation drive'') approach converts laser light to x-rays inside a gold cylinder, which then acts as an x-ray ''oven'' (called a hohlraum) to drive the fusion capsule in its center. On Nova we've demonstrated good understanding of the temperatures reached in hohlraums and of the ways to control the uniformity with which the x-rays drive the spherical fusion capsules. In these lectures we will be reviewing the physics of these laser heated hohlraums, recent attempts at optimizing their performance, and then return to the ICF problem in particular to discuss scaling of ICF gain with scale size, and to compare indirect vs. direct drive gains. In ICF, spherical capsules containing Deuterium and Tritium (DT)--the heavy isotopes of hydrogen--are imploded, creating conditions of high temperature and density similar to those in the cores of stars required for initiating the fusion reaction. When DT fuses an alpha particle (the nucleus of a helium atom) and a neutron are created releasing large amount amounts of energy. If the surrounding fuel is sufficiently dense, the alpha particles are stopped and can heat it, allowing a self-sustaining fusion burn to propagate radially outward and a high gain fusion micro-explosion ensues. To create those conditions the outer surface of the capsule is heated (either directly by a laser or indirectly by laser produced x-rays) to cause rapid ablation and outward expansion of the capsule material. A rocket-like reaction to that outward flowing heated material leads to an inward implosion of the remaining part of the capsule shell. The pressure generated on the outside of the capsule can reach nearly 100 megabar (100 million times

  4. ICF research at Los Alamos

    International Nuclear Information System (INIS)

    It is apparent that short wavelength lasers (<500 nm) provide efficient coupling of laser energy into ICF target compression. KrF lasers (248 nm) operate at near-optimum wavelength and provide other potential benefits to ICF target coupling (e.g., bandwidth) and applications (high wallplug efficiency and relatively low cost). However, no driver technology has yet been shown to meet all of the requirements for a high-gain ICF capability at a currently acceptable cost, and there are still significant uncertainties in the driver-target coupling and capsule hydrodynamics that must be addressed. The Los Alamos research program is designed to assess the potential of KrF lasers for ICF and to determine the feasibility of achieving high gain in the laboratory with a KrF laser driver. Major efforts in KrF laser development and technology, target fabrication and materials development, and laser-matter interaction and hydrodynamics research are discussed. 27 refs., 10 figs

  7. Identification and expression of capa gene in the fire ant, Solenopsis invicta.

    Directory of Open Access Journals (Sweden)

    Man-Yeon Choi

    Full Text Available Recent genome analyses suggested the absence of a number of neuropeptide genes in ants. One of the apparently missing genes was the capa gene. Capa gene expression in insects is typically associated with the neuroendocrine system of abdominal ganglia; mature CAPA peptides are known to regulate diuresis and visceral muscle contraction. The apparent absence of the capa gene raised questions about possible compensation of these functions. In this study, we re-examined this controversial issue and searched for a potentially unrecognized capa gene in the fire ant, Solenopsis invicta. We employed a combination of data mining and a traditional PCR-based strategy using degenerate primers designed from conserved amino acid sequences of insect capa genes. Our findings demonstrate that ants possess and express a capa gene. As shown by MALDI-TOF mass spectrometry, processed products of the S. invicta capa gene include three CAPA periviscerokinins and low amounts of a pyrokinin which does not have the C-terminal WFGPRLa motif typical of CAPA pyrokinins in other insects. The capa gene was found with two alternative transcripts in the CNS. Within the ventral nerve cord, two capa neurons were immunostained in abdominal neuromeres 2-5, respectively, and projected into ventrally located abdominal perisympathetic organs (PSOs, which are the major hormone release sites of abdominal ganglia. The ventral location of these PSOs is a characteristic feature and was also found in another ant, Atta sexdens.

    Full Text Available A common method for obtaining colour coatings on stainless steel surfaces is by dipping in strongly oxidizing solutions (H2SO4-CrO3 at 70°C. This work improves the knowledge of these coatings by means of techniques that were not available some years ago, such as ellipsometry, to determine the refraction index and the thickness, and atomic field microscopy (AFM, to observe the coloured surface. From these techniques, it is possible to state that films are formed by an aggregation of particle ranging in size from 5 to 15 nm, the interstices are pores of approximately 5 nm diameter.

    El método más usual de obtener en la superficie de los aceros inoxidables capas de colores variables es mediante su inmersión en soluciones fuertemente oxidantes (H2SO4-CrO3 a una temperatura en torno a 70°C. El trabajo mejora el conocimiento que de estas capas se tiene por medio de técnicas que no eran disponibles hace algunos años, tales como la elipsometría, para la obtención de parámetros ópticos y determinación de espesores, y la microscopía de campo atómico, para la observación de la superficie coloreada. El uso conjunto de estas técnicas permite observar que la película de color está formada por una agregación de partículas con un tamaño que oscila entre los 5 y los 15 nm, los intersticios que aparecen entre las partículas pueden identificarse como poros de unos 5 nm de tamaño.

  14. ICF target positioning robot system

    International Nuclear Information System (INIS)

    Based on the function analysis of target positioner for inertial confinement fusion, a kind of ICF target positioning robot system is designed to realize the adjustment and the alignment of a target. The robot system includes a target storage sub-system, a target exchange subsystem, a target transport subsystem and a 6-degree of freedom precision parallel robot subsystem, the structure and principle of every subsystem are dissertated. The system realizes micro scale position by parallel structure which is in the front of the system, and has the advantages of low mass, high stiffness, small cone angle, small volume and high precision. The robot system can position a target into a very small micro scale scope around the center of the target chamber whose diameter is several meters, the precision of the position reaches micro scale. Motion parameter of the positioning robot system has been tested. Experiment proves that the robot system has realized precision target position and target exchange on the condition of vacuum.

    2009-03-01

    Full Text Available Abstract Background The International Classification of Functioning, Disability and Health (ICF is embraced as a framework to conceptualize human functioning and disability. Health professionals choose measures to represent the domains of the framework. The ICF coding classification is an administrative system but multiple studies have linked diverse clinical assessments to ICF codes. InterRAI-HC (home care is an assessment designed to assist planning of care for patients receiving home care. Examining the relationship between the ICF and the interRAI HC is of particular interest because the interRAI assessments are widely used in clinical practice and research, are computerized, and uploaded to databases that serve multiple purposes including public reporting of quality in Canada and internationally. The objective of this study was to examine the relationship between the interRAI HC (home care assessment and the ICF. Specifically, the goal was to determine the proportion of interRAI HC items that can be linked to each of the major domains of the ICF (Body Function, Body Structure, Activities and Participation, and the Environmental Factors, the chapters and the specific ICF codes. Methods Three coders who were familiar with both the home care assessment and the ICF independently assigned ICF codes to inter-RAI HC items. Subsequently, a series of teleconference meetings were held to reach consensus on the primary code and much later consensus was used to finalize codes for additional items added to the interRAI HC. Results Following exclusion of administrative and diagnostic sections, 175 interRAI items were examined for potential assignment of codes. Of these 52 were assigned codes related to body function, 43 to activities and participation, 34 to environment, 1 to body structure, 17 to not coded, and 26 to not defined. Considering all 3-digit ICF codes, interRAI items addressed 43.2% of Body Function and 50.6% of Activities and Participation

    Full Text Available The first CAPA peptides of insects were identified from Periplaneta americana using extracts of 8000 abdominal perisympathetic organs. The corresponding gene of cockroaches and other basal insects, however, remained undiscovered. Here we identified two capa cDNA transcripts of P. americana. Single cell mass spectrometry of capa neurons in abdominal ganglia yielded a complete coverage of the precursor sequences of both transcripts; with intermediates of precursor processing more prominent in somata than in perisympathetic organs. The processing of the CAPA precursor in P. americana is compared with that in the beetle Tribolium castaneum which was re-evaluated in this study.

    Full Text Available Like the whole sub-Sahara Africa, rainfall in Fina reserve is subject of strong inter-annual variability. This paper assesses farmers’ perception on land use utilised in the Fina biosphere reserve and their adaptation measures to climate variability. The statistical methods (descriptive and inferential analysis are used in this study to determine farmers’ perceptions and the adaptation measures in the Fina reserve. Results reveal that 75.5% of the farmers noticed an increase in temperature and decrease in rainfall ignoring the recent recovery observed in the annual rainfall. The length of rainy season is considered to be shorter according to 77.6% of farmers involved to the investigation. However, all the farmers underlined frequent and longer dry spell. Bush fire is considered by 10.2% of farmers as the major factor affecting the natural resources of the reserve and only about 10% of farmers accorded much importance to agricultural land as contributor to reserve degradation. Most of the farmers are limited by lack of manpower and not by the reserve rule to increase their farmlands. The major adaptation measures are the methods of shifting cultivation and improving seed which are practiced by 51% and 87.8% of farmers, respectively. New adaptation strategies such as adoption of planting pits and stone-bunds for water retention need to be practiced by farmers.

  2. Progress of inertial confinement fusion (ICF) research

    International Nuclear Information System (INIS)

    In this article, we briefly describe the recent progress of ICF research. Four topics in this field are selected which are considered as the most important at present. These are the 'Cannonball' target; high power krypton fluoride (KrF) laser; Ion beam diodes and imploding foil/plasma. About the 'Cannonball' target, its principle and its advantages over the ordinary ablation drive are given. It is particularly indicated that by using this type of target, the Japanese researchers have gotten, thus far, the highest yield of neutrons in the world, i. e. 4 x 1010 neutrons per pulse. The important problem of hole sealing of such target is also discussed. The second topic described above is the powerful KrF excimer laser pumped by electron beams. This laser is now generally regarded as one of more promising lasers as a driver for ICF. Here we briefly describe the complex kinetics of pumping, quenching, radiation and absorption of this very interesting laser. A compression of KrF laser pulse length from about 100 nanosecond (ns) to a few ns is necessary for ICF work. We describe three of the compression methods, namely: pulse spletting and then stacking; Raman back scattering and the mixing of these two. In the third topic it is discussed on the present status of ion beam production, especially on the diodes which produce the ion beams. Three kinds of the diodes are mentioned. These are pinched reflex diode (PRD), diode with externally applied magnetic field and hybrid amphion diode. New works of Reiden-IV, in Institute of Laser Engineering, Osaka and Etigol in Nagaoka Technical University, Nagaoka are also reported. The 4th topic concerned is the imploding foil/plasma. This method can produce plasma of very high temperature and very intensive soft X-ray which may either be used to produce X-ray laser or used as a new driver for ICF

    2016-05-01

    We are developing a new NIF experimental platform that employs wetted foam liquid fuel layer ICF capsules. We will use the liquid fuel layer capsules in a NIF sub-scale experimental campaign to explore the relationship between hot spot convergence ratio (CR) and the predictability of hot spot formation. DT liquid layer ICF capsules allow for flexibility in hot spot CR via the adjustment of the initial cryogenic capsule temperature and, hence, DT vapor density. Our hypothesis is that the predictive capability of hot spot formation is robust and 1D-like for a relatively low CR hot spot (CR∼15), but will become less reliable as hot spot CR is increased to CR>20. Simulations indicate that backing off on hot spot CR is an excellent way to reduce capsule instability growth and to improve robustness to low-mode x-ray flux asymmetries. In the initial experiments, we will test our hypothesis by measuring hot spot size, neutron yield, ion temperature, and burn width to infer hot spot pressure and compare to predictions for implosions with hot spot CR's in the range of 12 to 25. Larger scale experiments are also being designed, and we will advance from sub-scale to full-scale NIF experiments to determine if 1D-like behavior at low CR is retained as the scale-size is increased. The long-term objective is to develop a liquid fuel layer ICF capsule platform with robust thermonuclear burn, modest CR, and significant α-heating with burn propagation.

    2015-01-01

    The effects of viscosity and small-scale atomic-level mixing on plasmas in inertial confinement fusion (ICF) currently represent challenges in ICF research. Many current ICF hydrodynamic codes ignore the effects of viscosity though recent research indicates viscosity and mixing by classical transport processes may have a substantial impact on implosion dynamics. We have implemented a Lagrange hydrodynamic code in one-dimensional spherical geometry with plasma viscosity and mass transport and including a three temperature model for ions, electrons, and radiation treated in a gray radiation diffusion approximation. The code is used to study ICF implosion differences with and without plasma viscosity and to determine the impacts of viscosity on temperature histories and neutron yield. It was found that plasma viscosity has substantial impacts on ICF shock dynamics characterized by shock burn timing, maximum burn temperatures, convergence ratio, and time history of neutron production rates. Plasma viscosity reduc...

  8. Simultaneous description of CF, ICF and TF data of 6,7Li + 209Bi reaction using new ICF mode

    International Nuclear Information System (INIS)

    The systematic behavior of the fusion suppression factors and ICF probability as a function of target mass is not well understood, despite the CF experimental data being available for a number of projectile-target systems. In our recent paper, a new method was proposed to calculate the ICF probability which is based on absorption cross sections obtained from the CDCC calculations. In continuation of this work, we have also carried out similar calculations for 6,7Li + 209Bi where the experimental data of CF and ICF is available. In the recent paper by Marta et al., the semi-classical model calculations were attempted to understand CF and ICF data for 6,7Li + 209Bi, which was not explaining the data quite well. Here, we have demonstrated the use of quantum mechanical treatment for simultaneous explanation of CF, ICF and TF over a large energy range

    Full Text Available Abstract Background The International Classification of Functioning, Disability and Health (ICF is the framework developed by WHO to describe functioning and disability at both the individual and population levels. While condition-specific ICF Core Sets are useful, a Generic ICF Core Set is needed to describe and compare problems in functioning across health conditions. Methods The aims of the multi-centre, cross-sectional study presented here were: a to propose a method to select ICF categories when a large amount of ICF-based data have to be handled, and b to identify candidate ICF categories for a Generic ICF Core Set by examining their explanatory power in relation to item one of the SF-36. The data were collected from 1039 patients using the ICF checklist, the SF-36 and a Comorbidity Questionnaire. ICF categories to be entered in an initial regression model were selected following systematic steps in accordance with the ICF structure. Based on an initial regression model, additional models were designed by systematically substituting the ICF categories included in it with ICF categories with which they were highly correlated. Results Fourteen different regression models were performed. The variance the performed models account for ranged from 22.27% to 24.0%. The ICF category that explained the highest amount of variance in all the models was sensation of pain. In total, thirteen candidate ICF categories for a Generic ICF Core Set were proposed. Conclusion The selection strategy based on the ICF structure and the examination of the best possible alternative models does not provide a final answer about which ICF categories must be considered, but leads to a selection of suitable candidates which needs further consideration and comparison with the results of other selection strategies in developing a Generic ICF Core Set.

    The transformation of International Classification of Impairments, Disabilities and Handicaps into International Classification of Functioning, Disability and Health (ICF) meant a lot for those needing to communicate in terms of functioning concept in their daily work. With ICF's commonly understood language, the decades' uncertainty on what concepts and terms describe functioning and disabilities seemed to be dispelled. Instead, operationalizing ICF to measure the level of functioning along with the new nomenclature has not been as unambiguous. Transforming linguistic terms into quantified functioning seems to need another type of theorizing. Irrespective of challenging tasks, numerous projects were formulated during the past decades to apply ICF for measurement purposes. This article updates one of them, the so-called biopsychosocial-ICF model, which uses all ICF categories but classifies them into more components than ICF for measurement purposes. The model suggests that both disabilities and functional resources should be described by collecting and organizing functional measurement data in a multidisciplinary, biopsychosocial data matrice.

    The chemical resistance of ceramic glazes susceptible to it, and more specifically the glazes formulated with a calcium matt frit, is enhanced by depositing on the surface a thin layer of zirconium oxide. A stabilized zirconia sol is the precursor of the layer, which is deposited by spray painting over the glaze, and with a mild heat treatment (T{sub m}ax {approx}{approx} 400 degree centigrade) is transformed into ZrO{sub 2} and anchored to the glazes surface. Chemical resistance tests show that the protected glaze does not suffer a visually significant attack by concentrated hydrochloric acid, conditions under which the same glaze without the coating is severely damaged. The used precursor generates a zirconium oxide layer that protects the underlying glaze, so that the chemical attack by the hydrochloric acid is confined to cracks and discontinuities in the deposited layer.

    In the last few years there has been significant progress in ICF research in laboratories in the United States and elsewhere. These advances have occurred in areas that range from demonstrating an innovative laser beam smoothing techniques important for both directly and indirectly driven ICF, to achieving a more complete understanding of capsule implosions and related physics. This progress has been possible because of the capabilities provided by the ICF laser-target facilities currently in operation and the new developments in diagnostics, particularly for measurements of the implosion process and the conditions in the compressed capsule core. Both of these topics, facilities and selected new diagnostics capabilities in the US ICF Program, are summarized in this paper. 32 refs., 19 figs., 6 tabs

    Reaction history measurements, such as nuclear bang time and burn width, are fundamental components of diagnosing ICF implosions and will be employed to help steer the National Ignition Facility (NIF) towards ignition. Fusion gammas provide a direct measure of nuclear interaction rate (unlike x-rays) without being compromised by Doppler spreading (unlike neutrons). Gas Cherenkov Detectors that convert fusion gamma rays to UV/visible Cherenkov photons for collection by fast optical recording systems have established their usefulness in illuminating ICF physics in several experimental campaigns at OMEGA. In particular, bang time precision better than 25 ps has been demonstrated, well below the 50 ps accuracy requirement defined by the NIF. NIF Gamma Reaction History (GRH) diagnostics are being developed based on optimization of sensitivity, bandwidth, dynamic range, cost, and NIF-specific logistics, requirements and extreme radiation environment. Implementation will occur in two phases. The first phase consists of four channels mounted to the outside of the target chamber at {approx}6 m from target chamber center (GRH-6m) coupled to ultra-fast photo-multiplier tubes (PMT). This system is intended to operate in the 10{sup 13}-10{sup 17} neutron yield range expected during the early THD campaign. It will have high enough bandwidth to provide accurate bang times and burn widths for the expected THD reaction histories (> 80 ps fwhm). Successful operation of the first GRH-6m channel has been demonstrated at OMEGA, allowing a verification of instrument sensitivity, timing and EMI/background suppression. The second phase will consist of several channels located just inside the target bay shield wall at 15 m from target chamber center (GRH-15m) with optical paths leading through the cement shield wall to well-shielded streak cameras and PMTs.

It will have high enough bandwidth to provide accurate bang times and burn widths for the expected THD reaction histories (> 80 ps fwhm). Successful operation of the first GRH-6m channel has been demonstrated at OMEGA, allowing a verification of instrument sensitivity, timing and EMI/background suppression. The second phase will consist of several channels located just inside the target bay shield wall at 15 m from target chamber center (GRH-15m) with optical paths leading through the cement shield wall to well-shielded streak cameras and PMTs. This system is intended to operate in the 1016-1020 yield range expected during the DT ignition campaign, providing higher temporal resolution for the

    The ICF Program in China has made significant progress with multilabs' efforts in the past years. The eight-beam SG-II laser facility, upgraded from the two-beam SG-I facility, is nearly completed for 1.05 μm light output and is about to be operated for experiments. Some benchmark experiments have been conducted for disk targets. Advanced diagnostic techniques, such as an x-ray microscope with a 7-μm spatial resolution and x-ray framing cameras with a temporal resolution better than 65ps, have been developed. Lower energy pumping with prepulse technique for Ne-like Ti laser at 32.6nm has succeeded and shadowgraphy of a fine mesh has been demonstrated with the Ti laser beam. A national project, SG-III laser facility, has been proposed to produce 60 kJ blue light for target physics experiments and is being conceptually designed. New laser technology, including maltipass amplification, large aperture plasma electrode switches and laser glass with fewer platinum grains have been developed to meet the requirements of the SG-III Project. The Technical Integration Line (TIL) as a scientific prototype beamlet of SG-III will be first built in the next few years.

    In the 01-ERD-107 LDRD-ER project, we have performed novel Thomson scattering experiments at the Trident and Omega laser facilities and provided high quality spectral data. These results have led to the development of the first quantitative understanding of laser-plasma interactions for NIF plasmas. For this purpose an green/ultraviolet probe laser, built for Nova in 1998 [1] and successfully used to measure both temperature and plasma wave amplitudes [2], has been deployed on Omega. The Thomson scattering diagnostics has been used twofold: (1) it provided independent measurements of the plasma electron and ion temperature, the plasma flow velocity, or the electron distribution function; (2) it provided measurements of the primary plasma wave and their secondary non-linear decay wave products. These experiments at Omega provide definitive quantitative results on the nonlinear saturation of stimulated Raman scattering for green (2{omega}) beams. In addition, the experiments on the Trident laser have led to a quantitative understanding of the stimulated Brillouin scattering in low-Z plasmas. A nonlinear frequency detuning model has successfully explained all the experimental observable including the SBS reflectivity. This model has been implemented into the laser-plasma interaction code pF3D as a tool to design and optimize NIF target experiments with SBS and SRS losses included. The development of quantitative models for SBS and SRS for various regimes has now been adopted as part of the WBS1 project within the ICF program.

    Local Thermodynamic Equilibrium (LTE) opacity codes have been developed by the Instituto de Fusion Nuclear (DENIM) during the last years. JIMENA code (Laser and Particle Beams 6 (1998) 265; Laser and Particle Beams 10 (1992) 651) is an opacity code that solves self-consistently, for each temperature and density, the radial Dirac equation with a local spherically symmetrical potential. Very recently we have developed a new opacity code, called ANALOP, that uses an analytical potential (JQSRT 54 (1995) 621), which can include density and temperature effects for atomic data calculations. Opacities are determined with these two codes for selected elements at different plasma conditions. This work is focused on the determination of Rosseland and Planck mean analytical formulas for several single elements used in ICF targets. A scaling law of these mean opacities is given as a function of the plasma parameters: electron temperature and plasma density. These opacities have been tested with numerical results from other codes and with available experimental results.

  1. Radiative heat transport instability in ICF plasmas

    2015-11-01

    A laser produced high-Z plasma in which an energy balance is achieved due to radiation losses and radiative heat transfer supports ion acoustic wave instability. A linear dispersion relation is derived and instability is compared to the radiation cooling instability. This instability develops in the wide range of angles and wavenumbers with the typical growth rate on the order of cs/LT (cs is the sound speed, LT is the temperature scale length). In addition to radiation dominated systems, a similar thermal transport driven ion acoustic instability was found before in plasmas where the thermal transport coefficient depends on electron density. However, under conditions of indirect drive ICF experiments the driving term for the instability is the radiative heat flux and in particular, the density dependence of the radiative heat conductivity. A specific example of thermal Bremsstrahlung radiation source has been considered corresponding to a thermal conductivity coefficient that is inversely proportional to the square of local particle density. In the nonlinear regime this instability may lead to plasma jet formation and anisotropic x-ray generation.

    Full Text Available MoS2 coatings, deposited by PVD show a low friction under vacuum conditions, but degrade easily under atmospheric conditions. This work describes the development of a new type of MoSx, coating, modified with WC. These coatings presented a very low and stable friction coefficient lower than 0.04 when tested under vacuum at 0.75 GPa in a ball on disc tribometer. Durability was higher than 1 million wear cycles, showing a wear rate of 1.3 10-16 m3/Nm. When tested under atmospheric conditions and up to 70 % RH, friction increased to 0.15 and durability reached a lower value of up to 3 x 105 cycles. Surface analyses in these coatings showed S/Mo ratios higher than 1.2 and with oxygen levels lower than 2 %, demonstrating the lubricant character of the coating.

    Full Text Available Double-layer tensegrity grids (DLTGs are tensegrity spatial systems containing two parallel networks of members in tension forming the top and bottom chords, whose nodes are linked by vertical and/or inclined web members under compression and tension. This paper presents, as an introduction, a brief perspective of the historical proposals for DLTGs over the last years, describing later a new approach for generating these kinds of structures, mainly in geometrical terms. After applying Otero’s proposal for designing conventional double-layer grids (DLGs, a new technique, known as Rot-Umbela Manipulation, is applied to their upper and/or lower layers for generating DLTGs. Rot-Umbela Manipulation consists of opening a vertex in the plane for obtaining a certain polygon, which is then rotated by a determined angle. This powerful operation opens an endless catalogue of DLTGs and a very interesting line of research in the field of Tensegrity.

    Las mallas tensegríticas de doble capa (MTDC son estructuras de Tensegridad que contiene dos mallas traccionadas paralelas, unidas por otra capa intermedia compuesta por elementos comprimidos y traccionados verticales y/o diagonales. Este trabajo presenta inicialmente un breve repaso sobre las propuestas de MTDC que se han realizado hasta el momento, exponiendo luego una nueva metodología, eminentemente geométrica, para la generación de este tipo de estructuras tensegríticas. Tras aplicar la propuesta de Otero para generar mallas de doble capa (MDC convencionales, se procede a realizar Manipulaciones de Rot-Umbela en las capas inferior y/o superior para convertir dicha estructura en una MTDC. Las Manipulaciones de Rot-Umbela consisten en la apertura de cada vértice en un cierto polígono, al cual se le aplica una rotación o giro particular. Se consigue así un potente sistema para “tensegritizar” MDC convencionales y abrir una línea de investigación muy interesante en el campo de la

    Gamma rays produced in an ICF environment open up a host of physics opportunities we are just beginning to explore. A branch of the DT fusion reaction, with a branching ratio on the order of 2e-5 {gamma}/n, produces 16.7 MeV {gamma}-rays. These {gamma}-rays provide a direct measure of fusion reaction rate (unlike x-rays) without being compromised by Doppler spreading (unlike neutrons). Reaction-rate history measurements, such as nuclear bang time and burn width, are fundamental quantities that will be used to optimize ignition on the National Ignition Facility (NIF). Gas Cherenkov Detectors (GCD) that convert fusion {gamma}-rays to UV/visible Cherenkov photons for collection by fast optical recording systems established their usefulness in illuminating ICF physics in several experimental campaigns at OMEGA. Demonstrated absolute timing calibrations allow bang time measurements with accuracy better than 30 ps. System impulse response better than 95 ps fwhm have been made possible by the combination of low temporal dispersion GCDs, ultra-fast microchannel-plate photomultiplier tubes (PMT), and high-bandwidth Mach Zehnder fiber optic data links and digitizers, resulting in burn width measurement accuracy better than 10ps. Inherent variable energy-thresholding capability allows use of GCDs as {gamma}-ray spectrometers to explore other interesting nuclear processes. Recent measurements of the 4.44 MeV {sup 12}C(n,n{prime}) {gamma}-rays produced as 14.1 MeV DT fusion neutrons pass through plastic capsules is paving the way for a new CH ablator areal density measurement. Insertion of various neutron target materials near target chamber center (TCC) producing secondary, neutron-induced {gamma}y-rays are being used to study other nuclear interactions and as in-situ sources to calibrate detector response and DT branching ratio. NIF Gamma Reaction History (GRH) diagnostics, based on the GCD concept, are now being developed based on optimization of sensitivity, bandwidth

    2006-02-15

    Inertial confinement fusion (ICF) has progressed from the detonation of large-scale fusion explosions initiated by atomic bombs in the early 1950s to final preparations for initiating small-scale fusion explosions with giant lasers. The next major step after ignition will be development of high performance targets that can be initiated with much smaller, lower cost lasers. In the 21st century and beyond, ICF's grand challenge is to develop practical power plants that generate low cost, clean, inexhaustible fusion energy. In this chapter, I first describe the origin in 1960-61 of ICF target concepts, early speculations on laser driven 'Thermonuclear Engines' for power production and rocket propulsion, and encouraging large-scale nuclear explosive experiments conducted in 1962. Next, I recall the 40-year, multi-billion dollar ignition campaign - to develop a matched combination of sufficiently high-performance implosion lasers and sufficiently stable targets capable of igniting small fusion explosions. I conclude with brief comments on the NIF ignition campaign and very high-performance targets, and speculations on ICF's potential in a centuries-long Darwinian competition of future energy systems. My perspectives in this chapter are those of a nuclear explosive designer, optimistic proponent of ICF energy, and Livermore Laboratory leader. The perspectives of Livermore's post 1970 laser experts and builders, and laser fusion experimentalists are provided in a chapter written by John Holzrichter, a leading scientist and leader in Livermore's second generation laser fusion program. In a third chapter, Ray Kidder, a theoretical physicist and early laser fusion pioneer, provides his perspectives including the history of the first generation laser fusion program he led from 1962-1972.

This formation crops out widely in the Subbetic (External Zones of the Betic Cordillera. The Capas Rojas Formation presents a great uniformity in the wide sectors of this cordillera and has its equivalent in facies and age, in the Scaglia Rossa Formation of the Apennines and southern Alps and also in equally analogous formations in other Alpine Mediterranean domains. From the available sedimentological and paleoecological data, mainly from the macrofossils (isolated rudists and echinoids content and from the ichnofacies analysis, it is concluded that its deposition took place in a hemipelagic marine environment with a moderate depth (a few hundreds of metres during a long interval of time (40-50 Ma with a very low sedimentation rate (a few millimetres per thousand years. From the analysis of the evolution of the continental margin in which was deposited, and of their equivalents in other Alpine domains, is deduced that the beginning of its deposition recorded the end of the differentiation in troughs and swells of these passive margins in the advanced stages of the rifting, so that this unit, in wide sector of the basin covered areas with an irregular topography in the bottom, mainly controlled by faults and slowly leveled them.Se analizan las características (litofacies, biofacies, edad, potencia, etc. de la Formación Capas Rojas (Cretácico superior-Eoceno que aflora extensamente en el Subbético, dentro de las Zonas Externas de la Cordillera Bética.

  17. Optical design of Kirkpatrick-Baez microscope for ICF

    International Nuclear Information System (INIS)

    A new flux-resolution optical design method of Kirkpatrick-Baez microscope (KB microscope) is proposed. In X-ray imaging diagnostics of inertial confinement fusion(ICF), spatial resolution and flux are always the key parameters. While the traditional optical design of KB microscope is to correct on-axis spherical aberration and astigmatic aberration, flux-resolution method is based on lateral aberration of full field and astigmatic aberration. Thus the spatial resolution related to field dimension and light flux can be estimated. By the expressions of spatial resolution and actual limits in ICF, rules of how to set original structure and optical design flow are summarized. An instance is presented and it shows that the design has met the original targets and overcome the shortcomings of image characterization in compressed core by traditional spherical aberration correction.

  18. Hydrodynamics compression in inertial confinement fusion (ICF) plasma

    International Nuclear Information System (INIS)

    The hydrodynamics compression in ICF plasma has been theoretically studied using conservation equations. The study is based on single fluid plasma model. A comparison is made between shock and adiabatic compression. It seems that the amount of energy required to compress the fusion fuel by same factor is greater for strong shocks but is nearly same for weak shocks in comparison with the adiabatic compression. It can be inferred as conclusion that weak shocks are appropriate for compression in ICF. The ratio of pressure, density and temperature are obtained in terms of shock speed, i.e., in terms of mach numbers. The limitation of achievable density of fuel in shock is calculated beyond which there is expansion rather than compression. (author)

    The anisotropic NdFeB magnets were prepared from the melt-spun isotropic powders by CAPA process. The precursor isotropic magnet shows the uniform magnetic properties according to the overall position in the magnet. In the case of the anisotropic magnet, the outer position shows higher remanence and energy product compared to the center position. The magnetic properties of the anisotropic magnet obtained from Nd{sub 14}Fe{sub 80}B{sub 6} powders are B{sub r}=15kG, {sub i}H{sub c}=4.1kOe and BH{sub max}=36MGOe. In the case of addition of Zn to Nd{sub 14}Fe{sub 80}B{sub 6} powders, the energy product increased because of the improved coercivity. The magnetic properties of the Zn-added magnet are B{sub r}=14.5kG, {sub i}H{sub c}=9.7kOe and BH{sub max}=52MGOe. The Zn addition is effective to depress Nd{sub 2}Fe{sub 14}B grain growth of the interparticle regions during plastic deformation.

    Nanosecond Pulsed Power Science and Technology has its origins in the 1960s and over the past decade has matured into a flexible and robust discipline capable of addressing key physics issues of importance to Inertial Confinement Fusion (ICF) and high Energy Density Physics. The major leverage provided by pulsed power is its ability to generate and deliver high energy and high power at low cost and high efficiency. A low-cost, high-efficiency driver is important because of the very large capital investment required for multi-megajoule ignition-class systems. High efficiency is of additional importance for a commercially viable inertial fusion energy option. Nanosecond pulsed power has been aggressively and successfully developed at Sandia over the past twenty years. This effort has led to the development of unique multi-purpose facilities supported by highly capable diagnostic, calculational and analytic capabilities. The Sandia Particle-beam Fusion Program has evolved as part of an integrated national ICF Program. It applies the low-cost, high-efficiency leverage provided by nanosecond pulsed power systems to the longer-term goals of the national program, i.e., the Laboratory Microfusion Facility and Inertial Fusion Energy. A separate effort has led to the application of nanosecond pulsed power to the generation of intense, high-energy laboratory x-ray sources for application to x-ray laser and radiation effects science research. Saturn is the most powerful of these sources to date. It generates (approximately) 500 kilojoules of x-rays from a magnetically driven implosion (Z-pinch). This paper describes results of x-ray physics experiments performed on Saturn, plans for a new Z-pinch drive capability for PBFA-2, and a design concept for the proposed (approximately) 15 MJ Jupiter facility. The opportunities for ICF-relevant research using these facilities will also be discussed.

  8. X-ray ablation measurements and modeling for ICF applications

    X-ray ablation of material from the first wall and other components of an ICF (Inertial Confinement Fusion) chamber is a major threat to the laser final optics. Material condensing on these optics after a shot may cause damage with subsequent laser shots. To ensure the successful operation of the ICF facility, removal rates must be predicted accurately. The goal for this dissertation is to develop an experimentally validated x-ray response model, with particular application to the National Ignition Facility (NIF). Accurate knowledge of the x-ray and debris emissions from ICF targets is a critical first step in the process of predicting the performance of the target chamber system. A number of 1-D numerical simulations of NIF targets have been run to characterize target output in terms of energy, angular distribution, spectrum, and pulse shape. Scaling of output characteristics with variations of both target yield and hohlraum wall thickness are also described. Experiments have been conducted at the Nova laser on the effects of relevant x-ray fluences on various materials. The response was diagnosed using post-shot examinations of the surfaces with scanning electron microscope and atomic force microscope instruments. Judgments were made about the dominant removal mechanisms for each material. Measurements of removal depths were made to provide data for the modeling. The finite difference ablation code developed here (ABLATOR) combines the thermomechanical response of materials to x-rays with models of various removal mechanisms. The former aspect refers to energy deposition in such small characteristic depths ({approx} micron) that thermal conduction and hydrodynamic motion are significant effects on the nanosecond time scale. The material removal models use the resulting time histories of temperature and pressure-profiles, along with ancillary local conditions, to predict rates of surface vaporization and the onset of conditions that would lead to spallation.

  9. U.S. DOE driver development for ICF

    International Nuclear Information System (INIS)

    The goal of the Department of Energy (DOE) supported Inertial Confinement Fusion (ICF) Program is to produce pure fusion ignition with fusion yields of 200 to 1000 millions of joules, which could find several applications in the defence and in the electric power generation. The National Ignition Facility will operate in both direct and indirect driver modes, with a glass laser driver. However two other options have been developed to increase the energy efficiency: the Light Ion Pulsed Power program and the NIKE KrF laser. Heavy ion drivers are also investigated -Abstract only-.

  10. 3D Simulations of line emission from ICF capsules

    International Nuclear Information System (INIS)

    Line emission from ICF implosions can be used to diagnose the temperature of the DT fuel and provides an indication of the distortion in the fuel-pusher interface. 2D simulations have provided valuable insights into the usefulness of argon and titanium dopants as diagnostics of instabilities. Characterizing the effects of drive asymmetries requires 3D modeling with large demands for computer time and memory, necessitating the use of parallel computers. We present the results of some 3D simulations achieved with a code utilizing both shared memory and distributed parallelism. We discuss the code structure and related performance issues

    Full Text Available Cerium conversion coatings are formed on commercial galvanized steel and a generation mechanism is suggested. The best conversion coatings were found using 10,000 ppm CeCl3·7H2O + 0,3 % vol. of H2O2 with a pH of 1.3. A cathodic potential, -100 mV versus corrosion potential, was applied during the treatment at a constant temperature of 43 °C. SEM micrographs have revealed a non uniform coating thickness between 1-2 μm. Polarization curves in 3.56 wt. % NaCl exhibited an inhibition power of about 94 % with respect to the galvanized steel. The proposed mechanism suggests that the Ce (III ions in the solution were oxidized by H2O2 to Ce (IV which then precipitated as CeO2. The applied voltage could cause a higher presence of Ce3+ in the film maybe due to an electroreduction process of cerium (IV in the film to cerium (III.

    En el presente trabajo, se desarrollan capas de conversión de cerio sobre un acero galvanizado comercial, proponiéndose un mecanismo de formación de las mismas. Las condiciones óptimas de generación de la capa se consiguieron empleando una disolución de 10.000 ppm de CeCl3·7H2O + 0,3 % vol. de H2O2 ajustando el pH a 1,3. A su vez, para mejorar la adherencia y reducir el tiempo de tratamiento se realizó, durante los 10 min del tratamiento, una activación potenciostática a -100 mV respecto al potencial de corrosión, manteniéndose la temperatura a 43 °C. El estudio del corte transversal de las muestras mediante microscopía electrónica de barrido reveló que las capas de cerio poseen un espesor no uniforme de 1-2 μm. Los resultados electroquímicos indicaron que las capas de cerio generadas ofrecían porcentajes de inhibición del orden del 94 % en cloruro sódico. Un posible mecanismo de formación de la capa de conversión sería que los iones de cerio (III en solución se

    Reduced density plasma channels are essential for LIB transport from external diodes to an ICF pellet centered in the 2-4 MPa superheated steamfilled cavity of the Heavy Water ICF Reactor. Forming such channels by ohmic heating requires the initiation of straight arc discharges along each beamline. The goal of this thesis is to evaluate the threshold beamline preionization and applied electric field for arc initiation. The capability of several preionizers to produce a straight preionized trail is evaluated through a ten-group Boltzmann equation solver. Electron densities around 10/sup 17/ m/sup -3/ could be maintained in the trail by monojoule output external preionizers. Trail preionization through the co-application of UV and CO/sub 2/ lasers appears to be the most promising technique. UV laser preionization of NO(a/sup 4/..pi..) formed in the fireball shows also good prospective. The large divergence of soft x-ray sources reduces their attractivity. The E/N dependent electron transport properties are used to construct the first streamer model capable of evaluating the steady state streamer wave shape. The streamers-induced highly ionized filament transition into a multi-kA carrying plasma channel is simulated by a modified radiation-MHD one-dimensional code.

    Purpose. Guided by the World Health Organization\\'s International Classification of Functioning, Disability and Health (ICF), a measure of activity and participation (MAP) was developed and incorporated into the National Physical and Sensory Disability Database in Ireland. The aims of this article are to investigate and explore the relationship between the barriers, participation restriction and functioning levels experienced by people with disabilities. Method. Seven thousand five hundred and sixty-two personal interviews with people meeting specific eligibility criteria for registering onto the database were conducted across four health service executive regions in Ireland. Results. Overall, differences in barriers, participation restriction and activity limitations experienced by people with different types of disabilities were found to be significant. Furthermore, low functioning and experience of barriers were indicators of participation restriction. Conclusions. This article has shown that elements of the ICF have been successfully operationalised in a service planning tool through the development of the MAP. This provides a more holistic view of disability and will enable the impact of service interventions to be measured over time.

  16. Performance of the Aurora KrF ICF laser system

    International Nuclear Information System (INIS)

    Because short wavelength lasers are attractive for inertial confinement fusion (ICF), the Department of Energy is sponsoring work at Los Alamos National Laboratory in krypton-fluoride (KrF) laser technology. Aurora is a short-pulse, high-power, KrF laser system. It serves as an end-to-end technology demonstration prototype for large-scale ultraviolet laser systems for short wavelength ICF research. The system employs optical angular multiplexing and serial amplification by electron-beam-driven KrF laser amplifiers. The 1 to 5 ns pulse of the Aurora front end is split into 96 beams which are angularly and temporally multiplexed to produce a 480 ns pulse train for amplification by four KrF laser amplifiers. In the present system configuration half (48) of the amplified pulses are demultiplexed using different optical path lengths and delivered simultaneously to target. This paper discusses how the Aurora laser system has entered the initial operational phase by delivering pulse energies of greater than one kilojoule to target

  17. URA coded-aperture camera for ICF plasma diagnostics

    International Nuclear Information System (INIS)

    In the inertial confinement fusion (ICF) research, imaging for x-rays and high energy particles is regarded to be one of the most important techniques to solve the implosion dynamics. A single pinhole camera and a Fresnel zone plate (FZP) camera have been used as the imaging instrument so far. The single pinhole camera, however, has low SN ratio especially for a weak radiation source because of its small opening area. The FZP camera inevitably produces an artifact in the reconstructed image. The uniformly redundant arrays (URA) were predicted to be artifact-free and expected to superior to FZP. From the above consideration, the URA camera has been introduced to ICF research at Los Alamos National Laboratory. The authors have successfully applied the URA camera to x-ray imaging of a compressed core with a cannon ball target. The URA aperture consists of 2,046 square pinholes and was fabricated by a photo-etching method in a 10 μm thick nickel foil. Each pinhole size was 30 μm square that was made small compared to the center-to-center spacings of 50 μm for self-supporting. The pattern of pinhole arrays was based on a 31 x 33 element m-sequence URA

    The National Ignition Facility Project The mission of the National Ignition Facility (NIF) is to produce ignition and modest energy gain in inertial confinement fusion (ICF) targets. Achieving these goals will maintain U.S. world leadership in ICF and will directly benefit the U.S. Department of Energy (DOE) missions in national security, science and technology, energy resources, and industrial competitiveness. Development and operation of the NIF are consistent with DOE goals for environmental quality, openness to the community, and nuclear nonproliferation and arms control. Although the primary mission of inertial fusion is for defense applications, inertial fusion research will provide critical information for the development of inertial fusion energy. The NIF, under construction at Lawrence Livermore National Laboratory (LLNL), is a cornerstone of the DOE's science-based Stockpile Stewardship Program for addressing high-energy-density physics issues in the absence of nuclear weapons testing. In pursuit of this mission, the DOE's Defense Programs has developed a state-of-the-art capability with the NIF to investigate high-energy-density physics in the laboratory with a microfusion capability for defense and energy applications. As a Strategic System Acquisition, the NIF Project has a separate and disciplined reporting chain to DOE as shown below.

    The World Health Organization's International Classification of Functioning, Disability and Health (ICF) has provided a new foundation for our understanding of health, functioning, and disability. It covers most of the health and health-related domains that make up the human experience, and the most environmental factors that influence that experience of functioning and disability. With the exhaustive ICF, patients' functioning -including its components body functions and structures and activities and participation-, becomes a central perspective in medicine. To implement the ICF in medicine and other fields, practical tools (= ICF Core Sets) have been developed. They are selected sets of categories out of the whole classification which serve as minimal standards for the assessment and reporting of functioning and health for clinical studies and clinical encounters (Brief ICF Core Set) or as standards for multiprofessional comprehensive assessment (Comprehensive ICF Core Set). Different from generic and condition-specific health-status measures, the ICF Core Sets include important body functions and structures and contextual factors. The use of the ICF Core Sets provides an important step towards improved communications between healthcare providers and professionals, and will enable patients and their families to understand and communicate with health professionals about their functioning and treatment goals. Specific applications include multi- and interdisciplinary assessment in clinical settings and in legal expert evaluations and use in disease or functioning-management programs. The ICF has also a potential as a conceptual framework to clarify an interrelated universe of health-related concepts which can be elucidated based on the ICF and therefore will be an ideal tool for teaching students in all medical fields and may open doors to multi-professional learning.

    Full Text Available A baixa recuperação na flotação de partículas minerais finas e ultrafinas continua sendo um dos principais desafios da área de processamento mineral. As técnicas emergentes existentes para o aumento da recuperação destas partículas são baseadas em novos conceitos de otimização da “captura” de partículas por bolhas, através do aumento da probabilidade de colisão bolha-partícula, injetando bolhas médias (100 – 600 μm e pequenas (< 100 μm na célula de flotação. Dentre as técnicas existentes para a geração de bolhas pequenas, estão a flotação por ar dissolvido (FAD e a eletroflotação (EF. Na EF são empregadas microbolhas de oxigênio e hidrogênio, geradas a partir da decomposição eletrolítica da água. Estas bolhas, com diâmetros variando entre 20 a 50 µm, são menores que as obtidas na FAD. As unidades de EF são pequenas e compactas e apresentam baixos custos de manutenção e funcionamento, quando comparadas a outros processos de flotação. Diversos estudos têm demonstrado a viabilidade do processo de EF aplicado ao tratamento de águas e de efluentes industriais, porém poucos estudos abordam a utilização desta técnica na área de processamento mineral. Este trabalho apresenta uma revisão da literatura sobre a utilização da EF aplicada ao tratamento de partículas minerais finas e ultrafinas.

  3. ICF Ignition, the Lawson Criterion, and Comparison with MFE Ignition

    Science.gov (United States)

    Betti, R.

    2009-11-01

    The Lawson criterion, which determines the onset of thermonuclear ignition, is usually expressed through the product pτ > 10 atm . s, where p is the plasma pressure in atm and τ is the energy confinement time in seconds. In magnetic fusion devices, both the pressure and confinement time are routinely measured and the performance of each discharge can be assessed by comparing the value of pτ with respect to the ignition value (10 atm . s). In inertial confinement fusion, both p and τ cannot be directly measured and the performance of surrogate and/or subignited ICF implosions cannot be assessed with respect to the ignition condition. This makes it difficult to compare the performance of ICF implosions with that of magnetic fusion energy (MFE) discharges. Here, we define the meaning of ignition in ICF implosions and compare it to MFE ignition. We then show that a multidimensional ignition condition for inertial confinement fusion can be cast in a form that depends on three measurable parameters of the compressed-fuel assembly: the hot-spot ion temperature T, the neutron yield normalized to the 1-D prediction (yield over clean or YOC) and the total areal density ρR, which includes the cold shell's contribution. A family of marginal-ignition curves are derived in the ρR--T plane.footnotetext C. D. Zhou and R. Betti, Phys. Plasmas 15, 102707 (2008). On this plane, hydrodynamic-equivalent curves show how a given implosion would perform with respect to the ignition condition when the laser-driver energy is varied. Such a criterion can be used to measure the ignition marginfootnotetext D. S. Clark, S. W. Haan, and J. D. Salmonson, Phys. Plasmas 15, 056305 (2008). of NIF targets and to predict the performance of OMEGA targets when scaled up to NIF energies.

    Full Text Available El anodizado del aluminio es simplemente el refuerzo de un proceso natural y espontáneo: la formación de una capa de alúmina estable y protectora mediante la cual se pueden obtener películas con una subcapa exterior porosa que acepta coloración. Luego la operación de sellado permite la formación de una sustancia gelatinosa compuesta principalmente de bohemita, que obstruye los poros y mejora la conservación del aspecto superficial y la resistencia a la corrosión. Utilizando SEM y EDS, en este trabajo se estudiaron las causas de la degradación de la capa de sellado de algunas piezas de aluminio anodizado, independientemente del medio en donde está expuesto el material, y se encontró su origen en la fotodegradación de un aditivo orgánico añadido en exceso durante la operación de sellado.

  6. A proteomic approach for studying insect phylogeny: CAPA peptides of ancient insect taxa (Dictyoptera, Blattoptera as a test case

    Directory of Open Access Journals (Sweden)

    Gäde Gerd

    2009-03-01

    Full Text Available Abstract Background Neuropeptide ligands have to fit exactly into their respective receptors and thus the evolution of the coding regions of their genes is constrained and may be strongly conserved. As such, they may be suitable for the reconstruction of phylogenetic relationships within higher taxa. CAPA peptides of major lineages of cockroaches (Blaberidae, Blattellidae, Blattidae, Polyphagidae, Cryptocercidae and of the termite Mastotermes darwiniensis were chosen to test the above hypothesis. The phylogenetic relationships within various groups of the taxon Dictyoptera (praying mantids, termites and cockroaches are still highly disputed. Results Tandem mass spectrometry of neuropeptides from perisympathetic organs was used to obtain sequence data of CAPA peptides from single specimens; the data were analysed by Maximum Parsimony and Bayesian Interference. The resulting cladograms, taking 61 species into account, show a topology which is in general agreement with recent molecular and morphological phylogenetic analyses, including the recent phylogenetic arrangement placing termites within the cockroaches. When sequence data sets from other neuropeptides, viz. adipokinetic hormones and sulfakinins, were included, the general topology of the cladogram did not change but bootstrap values increased considerably. Conclusion This study represents the first comprehensive survey of neuropeptides of insects for solely phylogenetic purposes and concludes that sequences of short neuropeptides are suitable to complement molecular biological and morphological data for the reconstruction of phylogenetic relationships.

    Full Text Available El programa de monitoreo de capa activa (CALM fue desarrollado en las últimas décadas con la finalidad de comprender el impacto del cambio climático sobre los ambientes con permafrost. Este trabajo analiza los resultados obtenidos, en los últimos seis años, de los sitios CALM-S Irizar, Cráter Lake y Refugio Chileno, ubicados en Isla Decepción. En ellos se ha medido el espesor, el estado térmico y la distribución espacial de la capa activa. En los sitios Irizar y Refugio Chileno la evolución del espesor de capa activa varió interanualmente sin una clara tendencia dentro del corto período analizado; por el contrario, el sitio Cráter Lake evidenció una tendencia a la disminución de espesor. La distribución espacial como el espesor de dicha capa en los tres sitios de monitoreo, mostraron estar condicionados principalmente por la potencia de la cubierta de nieve, la litología y la exposición a los vientos. El relieve, la topografía de detalle, la orientación de las laderas frente a la radiación solar incidente, ejercieron un control menor sobre esta distribución. El estado térmico de la capa activa evidenció el control ejercido sobre ella de la temperatura del aire y de la cubierta nival. Así bajo reducidos espesores de nieve, el modelo de penetración en profundidad de la isoterma de 0 ºC, ha permitido aproximar satisfactoriamente el espesor de capa activa.

  8. The twin-fall concept for an ICF chamber

    International Nuclear Information System (INIS)

    A twin-fall concept, with a thin sacrificial inner fall and a thick outer annular fall, is proposed for use for energy conversion and structural protection of an advanced-fuel inertial confinement fusion (ICF) reactor. This scheme takes full advantage of the unique D-T ignited D-D-3He target yield, which is primarily in short range irradiation. A compact chamber, radius of 3 m, is achieved, giving a high energy density, low chamber costs, and effective heavy ion beam driver focusing. The reactor concept is named LOTRIT to emphasize the minimum tritium inventory due to combination of the target design and a selection of liquid lead as a chamber working fluid

    A conceptual design is presented of the main power amplifier of a multi-beamline, multi-megawatt solid state ICF reactor driver. Simultaneous achievement of useful beam quality and high average power is achieved by a proper choice of amplifier geometry. An amplifier beamline consists of a sequence of face-pumped rectangular slab gain elements, oriented at the Brewster angle relative to the beamline axis, and cooled on their large faces by helium gas that is flowing subsonically. The infrared amplifier output radiation is shifted to an appropriately short wavelength (<500 nm) using nonlinear crystals that are also gas cooled. We project an overall driver efficiency >10% (including all flow cooling input power) when the amplifiers are pumped by efficient high-power AlGaAs semiconductor laser diode arrays. 11 refs., 3 figs., 7 tabs.

    Olazabal-Loumé M.

    2013-11-01

    Full Text Available The effect of anisotropic diffusion on hydrodynamic instabilities in the context of Inertial Confinement Fusion (ICF flows is numerically assessed. This anisotropy occurs in indirect-drive when laminated ablators are used to modify the lateral transport [1,2]. In direct-drive, non-local transport mechanisms and magnetic fields may modify the lateral conduction [3]. In this work, numerical simulations obtained with the code PERLE [4], dedicated to linear stability analysis, are compared with previous theoretical results [5]. In these approaches, the diffusion anisotropy can be controlled by a characteristic coefficient which enables a comprehensive study. This work provides new results on the ablative Rayleigh-Taylor (RT, ablative Richtmyer-Meshkov (RM and Darrieus-Landau (DL instabilities.

    International Nuclear Information System (INIS)

    The Los Alamos National Laboratory Inertial Confinement Fusion (ICF) Program focuses on resolving key target-physics issues and developing technology needed for the National Ignition Facility (NIF). This work is being performed in collaboration with Lawrence Livermore National Laboratory (LLNL). A major requirement for the indirect-drive NIF ignition target is to achieve the irradiation uniformity on the capsule surface needed for a symmetrical high-convergence implosion. Los Alamos employed an integrated modeling technique using the Lasnex radiation-hydrodynamics code to design two different targets that achieve ignition and moderate gain. Los Alamos is performing experiments on the Nova Laser at LLNL in order to validate our NIF ignition calculations

  17. The INPORT concept - an improved method to protect ICF reactor first walls

    International Nuclear Information System (INIS)

    A method to protect the first metallic walls of ICF reactors from X-rays and target debris has been developed. The concept utilizes porous, flexible tubes of woven C or SiC fibers to contain liquid metals inside the vacuum chamber of an ICF system. These porous tubes allow for ablation and recondensation of liquid metal films. The tubes also moderate the neutron spectra and reduce the displacement and transmutation damage in metallic walls.

  20. Estudio teórico de la distribución catiónica en la capa octaédrica de silicatos laminares

    Hernández-Laguna, A.

    Los silicatos laminares son unos minerales de gran extensión en la corteza de nuestro y otros planetas, y se ha detectado su presencia en masas de partículas de polvo interplanatario. Están formados por láminas estructuradas en una capa tetraedros de sílice y una de octaédros de oxihidroxido de aluminio. Según el número de capas y la disposición aparecen distintos minerales. Además, también pueden aparecer distintos minerales como consecuencia de la substitución isomórfica de cationes en la capas, en particular, Al(III) por Si en la capa tetraédrica y Fe(III) y/o Mg(II) por Al(III) en la octaédrica. Cuando el catión substituyente presenta un estado de oxidación más bajo que al que substituye genera carga negativa que tiene que neutralizarse con cationes que se disponen en el espacio interlaminar. En este trabajo vamos a estudiar, mediante distintos métodos computacionales, las distribuciones de dichos cationes de substitución en la capa octaédrica de silicatos laminares 2:1 (dos capas tetraédricas y en medio una octaédrica), en particular, en los minerales esmectitas e ilitas. En primer lugar, estudiaremos la distribución de dichos cationes en la capa octaédrica en un modelo de gas reticular por el método de Monte Carlo, minimizando el número de pares de cationes Al, Fe y Mg de nuestro modelo con respecto a los procedentes de resultados espectroscópicos de muestras de minerales. Posteriormente, y mediante un modelo de potenciales empíricos, estudiamos la energética de las distribuciones binarias en dichos minerales, generando unos potenciales de interacción intercambio a dos y tres cationes (extrapolables a cualquier filosilicato) que son la base para una investigación Monte Carlo-"simulated-annealing" en la que se encuentran las transiciones de fase y las estructuras ordenadas, dependiendo dichas estructuras y la temperatura de cambio de fase de la de la naturaleza y concentración de los cationes de substitución.

    The ground-state rotational spectra of two weakly bound complexes B···ICF(3) (B = Kr or CO) formed by trifluoroiodomethane have been observed in pulsed jets by using two types of Fourier-transform microwave spectroscopy (chirped-pulse and Fabry-Perot cavity). Both complexes exhibit symmetric-top type spectra, thus indicating that the Kr atom in Kr···ICF(3) and both the C and O atoms in OC···ICF(3) lie along the C(3) axis of ICF(3). The rotational constant B(0), the centrifugal distortion constants D(J) and D(JK), and the iodine nuclear quadrupole coupling constant χ(aa)(I) were determined for each of the isotopologues (84)Kr···ICF(3), (86)Kr···ICF(3), (16)O(12)C···ICF(3), (16)O(13)C···ICF(3), and (18)O(12)C···ICF(3). Interpretation of the spectroscopic constants reveals that the carbon atom of CO is adjacent to I and participates in the weak bond in OC···ICF(3). Simple models based on unperturbed component geometries lead to the distances r(Kr···I) = 3.830(1) Å and r(C···I) = 3.428(1) Å in Kr···ICF(3) and OC···ICF(3), respectively, and to the quadratic force constants for stretching of the weak bond k(σ) = 2.80 N m(-1) and 3.96 N m(-1), respectively. The distances r(Z···I) (Z is the acceptor atom in B), the k(σ) values, and the angular geometries of the pair of complexes B···ICF(3) and B···ICl for a given B are compared when B = Kr, CO, H(2)O, H(2)S, or NH(3). The comparison reveals that the iodine bond in B···ICF(3) is systematically longer and weaker than that of B···ICl, while the angular geometry of the B···I moiety is isomorphic in B···ICF(3) and B···ICl for a given B. It is concluded that -CF(3) is less effective than -Cl as an electron-withdrawing group when attached to an I atom and that the angular geometries of the B···ICF(3) can be predicted by means of a simple rule that holds for many hydrogen- and halogen-bonded complexes.

    In this paper, we give a review of three hohlraum geometries, including cylindrical, octahedral and six-cylinder-port hohlraums, in inertial confinement fusion (ICF) mainly from theoretical side. Every hohlraum has its own strengths and weaknesses. Although there is a problem of drive asymmetry in the cylindrical hohlraums due to some non-ideal factors, the success of ignition is still possible if more laser energy is available beyond the US National Ignition Facility (NIF) in the future. Octahedral hohlraums can provide the high symmetry flux on capsule. However, octahedral hohlraums suffer from several problems due to the complicated three-dimensional plasma conditions inside. And up to now, there is no one target design with the octahedral hohlraums in which each problem can be solved at the same time. Six-cylinder-port hohlraums combine the merits in theory of both cylindrical and octahedral hohlraums to a certain extent. We introduce a target design with good performance by using the six-cylinder-port ho...

  4. Glass laser system, Gekko XII upgrade for ICF ignition

    International Nuclear Information System (INIS)

    Recent progresses have shown the possibility of the ignition at the inertial confinement fusion experiment in the direct drive scheme. The imploded core of burning temperature, 5-10 keV, and the imploded core of 600 times liquid fuel density have been realized separately at Osaka University by using less than 10 kJ energy with 3% energy balance. While the high temperature core could only generate the neutrons up to a level of one tenth to a hundredth predicted by the one dimensional calculation at a compression ratio over ten. The required energy and its uniformity on the spherical pellet are trade-off for given the resultant of the implosion. The key issue in the inertial fusion energy development is now the realization of the ignition which is one of milestones to the energy production by the ICF. In this report, the basic design of the Gekko XII upgrade system named open-quotes Kongohclose quotes at Osaka University is discussed with system components being developed now to improve the uniformity, controllability, and the energy delivering in the existing building of Gekko XII

    SCROLL is a collisional radiative model able to deal with complex spectra[1]. It is used to generate opacity/emissivity databases [2] compatible with the hydrocode FAST[3] for all elements of interest in the simulation of ICF targets, including high-Z. It is now modified to yield tables of EOS data for FAST, in the whole range of interest (T=1 to 25000eV, rho=10-6 to 100g/cc). SCROLL contributes the electronic -free and bound- part of the EOS, replacing Busquet's model of an ionization temperature. Ionization energies include contributions of all excited states. Energies and Z* go smoothly to the high density regime, where a "jellium" model is assumed. The free electrons are self consistent with the bound electrons. Examples of runs will be shown.

    Mixing at the fuel-ablator interface of an inertial confinement fusion (ICF) implosion can arise from an unfavorable in-flight Atwood number between the cryogenic DT fuel and the ablator. High-Z dopant is typically added to the ablator to control the Atwood number, but recent high-density carbon (HDC) capsules have been shot at the National Ignition Facility (NIF) without this added dopant. Highly resolved post-shot modeling of these implosions shows that there was significant mixing of ablator material into the dense DT fuel. This mix lowers the fuel density and results in less overall compression, helping to explain the measured ratio of down scattered-to-primary neutrons. Future experimental designs will seek to improve this issue through adding dopant and changing the x-ray spectra with a different hohlraum wall material. To test these changes, we are designing an experimental platform to look at the growth of this mixing layer. This technique uses side-on radiography to measure the spatial extent of an embedded high-Z tracer layer near the interface.

    We developed a number of new or improved metrology techniques to measure the spatial distributions of multiple elements in ICF ablator capsules to tight NIF specifications (0.5±0.1 at% Cu, 0.25±0.10 at% Ar, 0.4±0.4 at% O). The elements are either the graded dopants for shock timing, such as Cu in Be, or process-induced impurities, such as Ar and O. Their low concentration, high spatial variation and simultaneous presence make the measurement very difficult. We solved this metrology challenge by combining several techniques: Cu and Ar profiles can be nondestructively measured by operating Contact Radiography (CR) in a differential mode. The result, as well as the O profile, can be checked destructively by a quantitative Energy Dispersive Spectroscopy (EDS) method. Non-spatially resolved methods, such as absorption edge spectroscopy (and to a lesser accuracy, x-ray fluorescence) can calibrate the Ar and Cu measurement in EDS and CR. In addition, oxygen pick-up during mandrel removal can be validated by before-and-after CR and by density change. Use of all these methods gives multiple checks on the reported profiles.

  10. Developing an integrated biomedical and behavioural theory of functioning and disability: adding models of behaviour to the ICF framework.

    Science.gov (United States)

    Johnston, Marie; Dixon, Diane

    2014-01-01

    The International Classification of Functioning Disability and Health (ICF) offers an agreed language on which a scientific model of functional outcomes can be built. The ICF defines functional outcomes as activity and activity limitations (AL) and defines both in behavioural terms. The ICF, therefore, appears to invite explanations of AL as behaviours. Studies of AL find that psychological variables, especially perceptions of control, add to biomedical variables in predicting AL. Therefore, two improved models are proposed, which integrate the ICF with two psychological theories, the theory of planned behaviour (TPB) and social cognitive theory (SCT). These models have a sound evidence base as good predictors of behaviour, include perceived control constructs and are compatible with existing evidence about AL. When directly tested in studies of community and clinic-based populations, both integrated models (ICF/TPB and ICF/SCT) outperform each of the three basic models (ICF, TPB and SCT). However, when predicting activity rather than AL, the biomedical model of the ICF does not improve prediction of activity by TPB and SCT on their own. It is concluded that these models offer a better explanation of functional outcomes than the ICF alone and could form the basis for the development of improved models. PMID:25211207

    The new COBRA accelerator is being built in stages at the Laboratory of Plasma Studies in Cornell University where its applications will include extraction diode and ion beam research in support of the light ion inertial confinement fusion (ICF) program at Sandia National Laboratories. The 4- to 5-MV, 125- to 250-kA accelerator is based on a four-cavity inductive voltage adder (IVA) design. It is a combination of new ferromagnetically-isolated cavities and self magnetically insulated transmission line (MITL) hardware and components from existing Sandia and Cornell facilities: Marx generator capacitors, hardware, and power supply from the DEMON facility; water pulse forming lines (PFL) and gas switch from the Subsystem Test Facility (STF); a HERMES-III intermediate store capacitor (ISC); and a modified ion diode from Cornell`s LION. The present accelerator consists of a single modified cavity similar to those of the Sandia SABRE accelerator and will be used to establish an operating system for the first stage initial lower voltage testing. Four new cavities will be fabricated and delivered in the first half of FY96 to complete the COBRA accelerator. COBRA is unique in the sense that each cavity is driven by a single pulse forming line, and the IVA output polarity may be reversed by rotating the cavities 180{degrees} about their vertical axis. The site preparations, tank construction, and diode design and development are taking place at Cornell with growing enthusiasm as this machine becomes a reality. Preliminary results with the single cavity and short positive inner cylinder MITL configuration will soon be available.

    Full Text Available Abstract Background Demographic ageing will lead to increasing pressure on visual rehabilitation services, which need to be efficiently organised in the near future. The Dutch ICF Activity Inventory (D-AI was developed to assess the rehabilitation needs of visually impaired persons. This pilot study tests the feasibility of the D-AI using a computer-assisted telephone interview. Methods In addition to the regular intake, the first version of the D-AI was assessed in 20 patients. Subsequently, patients and intake assessors were asked to fill in an evaluation form. Based on these evaluations, a new version of the D-AI was developed. Results Mean administration time of the D-AI was 88.8 (± 41.0 minutes. Overall, patients and assessors were positive about the D-AI assessment. However, professionals and 60% of the patients found the administration time to be too long. All included items were considered relevant and only minor adjustments were recommended. Conclusion The systematic character of the revised D-AI will prevent topics from being overlooked and indicate which needs have the highest priority from a patient-centred perspective. Moreover, ongoing assessment of the D-AI will enhance evaluation of the rehabilitation process. To decrease administration time, in the revised D-AI only the top priority goals will be fully assessed. Using the D-AI, a rehabilitation plan based on individual needs can be developed for each patient. Moreover, it enables better evaluation of the effects of rehabilitation. A larger validation study is planned.

    2005-10-12

    The United States continues to maintain its leadership in ICF as it moves toward the goal of ignition. The flagship of the program is the National Ignition Facility (NIF) presently under construction at LLNL. Experiments had begun on the first four beams of the National Ignition Facility just at the time of the last IFSA Conference. Several new successful campaigns have been conducted since then in planar hydrodynamics and hohlraums as well as activating the VISAR diagnostic for equation of state experiments. Highlights of these results will be reviewed. Presently, the four beam experimental capability has been suspended while the first eight beams are being installed as the first step in building out the project. Meanwhile, much progress has been made in developing ignition designs for using NIF. An array of designs having several ablator materials have been shown computationally to ignite with energies ranging from the design energy to as low as 1 MJ of laser energy. Alternative direct drive designs in the NIF indirect drive configuration have been developed by LLE. This wide array of design choices has increased the chance of achieving ignition sooner on the facility. Plans are now being developed to begin an ignition experimental campaign on NIF in 2010, a little over a year after completion of the facility. Other US facilities are also implementing improved capabilities. Petawatt lasers are now under construction at the University of Rochester and Sandia National Laboratory. The Z pulsed power machine at Sandia National Laboratory is being refurbished to improve its performance. The ongoing research program at the OMEGA laser at the University of Rochester and the Z machine at Sandia National Laboratory as well as at the Nike, Trident and Janus lasers remain strong, performing experiments supporting the NIF ignition plan and direct drive ignition. There also is an active program in the broader field of high energy density science on these facilities. These

    International Nuclear Information System (INIS)

    Highlights: ► The laser coupling issue in the novel fiber-based ICF laser driver is analyzed. ► The requirements for the output capabilities of the fiber laser are given which provides some hint for future research of high energy fiber laser system. -- Abstract: Fiber-based inertial confinement fusion (ICF) laser driver provides a new pathway to realize the inertial fusion energy (IFE). The feasibility of this proposal is checked from the perspective of laser coupling process in this paper. Flattened Gaussian beam (FGB) is assumed for theoretical analysis. The focusing properties of the FGB are used to obtain the requirements for a single laser beam. Based on the typical parameters of the chamber and target in ICF research, the output energy from a single fiber amplification chain is estimated to be over several hundred milli-joule. New fiber structures needs to be designed to meet the requirements

  17. When Shape Matters: correcting the ICFs to derive the chemical abundances of bipolar and elliptical PNe

    Goncalves, D R; Morisset, C; Barlow, M; Ercolano, B

    2011-01-01

    The extraction of chemical abundances of ionised nebulae from a limited spectral range is usually hampered by the lack of emission lines corresponding to certain ionic stages. So far, the missing emission lines have been accounted for by the ionisation correction factors (ICFs), constructed under simplistic assumptions like spherical geometry by using 1-D photoionisation modelling. In this contribution we discuss the results (Goncalves et al. 2011, in prep.) of our ongoing project to find a new set of ICFs to determine total abundances of N, O, Ne, Ar, and S, with optical spectra, in the case of non-spherical PNe. These results are based on a grid of 3-D photoionisation modelling of round, elliptical and bipolar shaped PNe, spanning the typical PN luminosities, effective temperatures and densities. We show that the additional corrections --to the widely used Kingsburgh and Barlow (1994) ICFs-- are always higher for bipolars than for ellipticals. Moreover, these additional corrections are, for bipolars, up to:...

  1. Core science and technology development plan for indirect-drive ICF ignition. Revision 1

    International Nuclear Information System (INIS)

    To define the development work needed to support inertial confinement fusion (ICF) program goals, the authors have assembled this Core Science and Technology (CS and T) Plan that encompasses nearly all science research and technology development in the ICF program. The objective of the CS and T Plan described here is to identify the development work needed to ensure the success of advanced ICF facilities, in particular the National Ignition Facility (NIF). This plan is intended as a framework to facilitate planning and coordination of future ICF programmatic activities. The CS and T Plan covers all elements of the ICF program including laser technology, optic manufacturing, target chamber, target diagnostics, target design and theory, target components and fabrication, and target physics experiments. The CS and T Plan has been divided into these seven different technology development areas, and they are used as level-1 categories in a work breakdown structure (WBS) to facilitate the organization of all activities in this plan. The scope of the CS and T Plan includes all research and development required to support the NIF leading up to the activation and initial operation as an indirect-drive facility. In each of the CS and T main development areas, the authors describe the technology and issues that need to be addressed to achieve NIF performance goals. To resolve all issues and achieve objectives, an extensive assortment of tasks must be performed in a coordinated and timely manner. The authors describe these activities and present planning schedules that detail the flow of work to be performed over a 10-year period corresponding to estimated time needed to demonstrate fusion ignition with the NIF. Besides the benefits to the ICF program, the authors also discuss how the commercial sector and the nuclear weapons science may profit from the proposed research and development program

The CS and T Plan covers all elements of the ICF program including laser technology, optic manufacturing, target chamber, target diagnostics, target design and theory, target components and fabrication, and target physics experiments. The CS and T Plan has been divided into these seven different technology development areas, and they are used as level-1 categories in a work breakdown structure (WBS) to facilitate the organization of all activities in this plan. The scope of the CS and T Plan includes all research and development required to support the NIF leading up to the activation and initial operation as an indirect-drive facility. In each of the CS and T main development areas, the authors describe the technology and issues that need to be addressed to achieve NIF performance goals. To resolve all issues and achieve objectives, an extensive assortment of tasks must be performed in a coordinated and timely manner. The authors describe these activities and present planning schedules that detail the flow of work to be performed over a 10-year period corresponding to estimated time needed to demonstrate fusion ignition with the NIF. Besides the benefits to the ICF program, the authors also discuss how the commercial sector and the nuclear weapons science may profit from the proposed research and development program.

    estudia el efecto de la dispersion sísmica por la presencia de capas someras de alta velocidad, con contrastes y espesores variables, y su influencia en la información sísmica. A diferencia de los métodos convencionales de eliminacion de ruido de base fundamentalmente matemática, por ejemplo: F-K, Radón, se aplica un esquema determinístico basado en el modelamiento de propagación de ondas que reproduce las señales no deseadas (Ernst et al., 1998; Blonk et al., 1995; Blonk and Hermann, 1994. El entendimiento detallado del fenómeno que genera estas señales permite discernir lo que se considera ruido y, por tanto, definir estrategias para su atenuación (Lamer et al., 1983. Por la presencia de capas someras de alta velocidad, gran parte de la energía sísmica original se dispersa en estas capas y solo una pequeña fracción se transmite al interior de la Tierra, generando ruido coherente que enmascara la información proveniente de los reflectores mas profundos (Leslie and Evans, 1999. Se diseño un modelo 20 y se obtuvieron varios sismogramas sintéticos, La simulación muestra el mecanismo de dispersión relacionado con la inversion de velocidad en las capas mas someras, lo que permite caracterizar su influencia sobre los registros sísmicos.

    A framework for target diagnostic centralized control system (TDCCS) in inertial confinement fusion (ICF) experiment has been developed. The developed framework is based on the common object request broker architecture (CORBA) standard and part of the concept from the ICFRoot (a framework based on ROOT for ICF experiments) framework design. This framework is of a component architecture, including a message bus, command executer, status processor, parser and proxy. To test the function of the framework, a simplified prototype of the TDCCS has been developed as well.

    The USA Inertial Confinement Fusion (ICF) Program evolved from the Nuclear Test Program which had restricted shot opportunities for experimentalists to develop sophisticated experimental techniques. In contrast the ICF program in the US was able to increase the shot availability on its large facilities, and develop sophisticated targets and diagnostics to measure and understand the properties of the high energy density plasmas (HEDP) formed. Illustrative aspects of this evolution at Lawrence Livermore National Laboratory (LLNL), with examples of the development of diagnostics and target fabrication are described.

    Germanium doped carbon–hydrogen polymer (CH) by Glow Discharge Polymer (GDP) technique has become the preferred Inertial Confinement Fusion (ICF) target material. The nondestructive measurement of elements content in the ICF target has become a significant work in recent years. This paper presents the compositional and distributional results of the Germanium doped CH analysis. The Ge doped CH materials as thin film and as hollow sphere were investigated by the Rutherford Backscattering Spectroscopy (RBS) combined with the particle induced X-ray emission (PIXE) and the Elastic Recoil Detection Analysis (ERDA). The samples are thin film with 36 μm thickness and ICF target with 500–2000 μm diameter. The calibration and geometrical arrangement in the analysis of spherical target should be carefully considered in order to acquire accurate results. In the work, the uniformity of the sphere is shown and the ratio of carbon, hydrogen and germanium has been measured. The ratio values are in good agreement with the results obtained by the combustion method. In addition, the difference of the composition from thin film to hollow sphere is also discussed. This work demonstrates that nuclear microbeam analysis is an ideal method to evaluate the ICF target quality.

  9. Genome-Wide DNA Methylation Analysis Identifies Novel Hypomethylated Non-Pericentromeric Genes with Potential Clinical Implications in ICF Syndrome.

    Directory of Open Access Journals (Sweden)

    Full Text Available Immunodeficiency, centromeric instability and facial anomalies syndrome (ICF is a rare autosomal recessive disease, characterized by severe hypomethylation in pericentromeric regions of chromosomes (1, 16 and 9, marked immunodeficiency and facial anomalies. The majority of ICF patients present mutations in the DNMT3B gene, affecting the DNA methyltransferase activity of the protein. In the present study, we have used the Infinium 450K DNA methylation array to evaluate the methylation level of 450,000 CpGs in lymphoblastoid cell lines and untrasformed fibroblasts derived from ICF patients and healthy donors. Our results demonstrate that ICF-specific DNMT3B variants A603T/STP807ins and V699G/R54X cause global DNA hypomethylation compared to wild-type protein. We identified 181 novel differentially methylated positions (DMPs including subtelomeric and intrachromosomic regions, outside the classical ICF-related pericentromeric hypomethylated positions. Interestingly, these sites were mainly located in intergenic regions and inside the CpG islands. Among the identified hypomethylated CpG-island associated genes, we confirmed the overexpression of three selected genes, BOLL, SYCP2 and NCRNA00221, in ICF compared to healthy controls, which are supposed to be expressed in germ line and silenced in somatic tissues.In conclusion, this study contributes in clarifying the direct relationship between DNA methylation defect and gene expression impairment in ICF syndrome, identifying novel direct target genes of DNMT3B. A high percentage of the DMPs are located in the subtelomeric regions, indicating a specific role of DNMT3B in methylating these chromosomal sites. Therefore, we provide further evidence that hypomethylation in specific non-pericentromeric regions of chromosomes might be involved in the molecular pathogenesis of ICF syndrome. The detection of DNA hypomethylation at BOLL, SYCP2 and NCRNA00221 may pave the way for the development of specific

    Full Text Available Abstract Background The recovery of patients after an acute episode of illness or injury depends both on adequate medical treatment and on the early identification of needs for rehabilitation care. The process of early beginning rehabilitation requires efficient communication both between health professionals and the patient in order to effectively address all rehabilitation goals. The currently used nursing taxonomies, however, are not intended for interdisciplinary use and thus may not contribute to efficient rehabilitation management and an optimal patient outcome. The ICF might be the missing link in this communication process. The objective of this study was to identify the categories of the International Classification of Functioning, Disability and Health (ICF categories relevant for nursing care in the situation of acute and early post-acute rehabilitation. Methods First, in a consensus process, "Leistungserfassung in der Pflege" (LEP nursing interventions relevant for the situation of acute and early post-acute rehabilitation were selected. Second, in an integrated two-step linking process, two nursing experts derived goals of LEP nursing interventions from their practical knowledge and selected corresponding ICF categories most relevant for patients in acute and post-acute rehabilitation (ICF Core Sets. Results Eighty-seven percent of ICF Core Set categories could be linked to goals of at least one nursing intervention variable of LEP. The ICF categories most frequently linked with LEP nursing interventions were respiration functions, experience of self and time functions and focusing attention. Thirteen percent of ICF Core Set categories could not be linked with LEP nursing interventions. The LEP nursing interventions which were linked with the highest number of different ICF-categories of all were "therapeutic intervention", "patient-nurse communication/information giving" and "mobilising". Conclusion The ICF Core Sets for the acute

    The existence of efficient ion acceleration regimes in collective laser-plasma interactions opens up the possibility to develop high-energy physics facilities in conjunction with projects for inertial confinement nuclear fusion (ICF) and neutron spallation sources. In this paper, we show that the pulse compression requests to make operative these acceleration mechanisms do not fall in contradiction with current designs for an ICF driver. In particular, we discuss explicitly a solution that exploits optical parametric chirped pulse amplification and the intrinsic modularity of ICF power plants.

Methods A total of 433 patients with long sick-listing periods, 267 women and 166 men, were included in the study. All certificates exceeding 28 days of sick-listing sent to the local office of the Swedish Social Insurance Administration of a municipality in the Stockholm area were collected during four weeks in 2004-2005. ICD-10 medical diagnosis codes in the certificates were retrieved and free text information on disabilities in body function, body structure or activity and participation were coded according to ICF short version. Results In 89.8% of the certificates there were descriptions of disabilities that readily could be classified according to ICF. In a reliability test 123/131 (94% items of randomly chosen free text information were identically classified by two of the authors. On average 2.4 disability categories (range 0-9 were found per patient; the most frequent were 'Sensation of pain' (35.1% of the patients, 'Emotional functions' (34.1%, 'Energy and drive functions' (22.4%, and 'Sleep functions' (16.9%. The dominating ICD-10 diagnostic groups were 'Mental and behavioural disorders' (34.4% and 'Diseases of the musculoskeletal system and connective tissue' (32.8%. 'Reaction to severe stress and adjustment disorders' (14.7%, and 'Depressive episode' (11.5% were the most frequent diagnostic codes. Disabilities in mental functions and activity/participation were more commonly described among women, while disabilities related to the musculoskeletal system were more frequent among men. Conclusions Both ICD-10 diagnoses and ICF categories were dominated by mental and musculoskeletal health problems, but there seems to be gender

    Full Text Available En los acantilados del cabo Ladrillero, situado sobre la costa atlántica de la Isla Grande de Tierra del Fuego, afloran parte de los depósitos cuspidales que rellenan la cuenca de antepaís Austral o de Magallanes. Estos depósitos del Mioceno inferior son conocidos como "capas del Cabo Ladrillero" y "capas del Cabo San Pablo", siendo las "capas del Cabo Ladrillero superior" las analizadas en este trabajo. La zona de estudio, situada a una decena de kilómetros al norte del frente orogénico emergente (Punta Gruesa, permitió reconocer cuatro asociaciones de facies que registran depósitos gravitacionales resedimentados en un ambiente marino supra batial y una cuña deltaica progradante y somerizante hacia el noreste. Entre los rasgos más conspicuos observados en esta sucesión se destacan bancos deformados, intervalos macizos y abundantes diques clásticos, cuyo análisis estadístico indica un patrón transtensivo. Los microfósiles documentados en el área y utilizados previamente como herramienta para sostener un ambiente marino profundo provienen de niveles estratigráficos infrayacentes y corresponden a niveles de la Formación Desdémona y las capas del Cabo Ladrillero inferior, aflorantes hacia el sur de la zona de estudio. Las evidencias sedimentológicas no son concluyentes respecto de la batimetría, pero la ausencia de turbiditas clásicas, flujos hiperpícnicos, la abundancia de bancos deformados y resedimentados, restos vegetales y fragmentos de carbón son compatibles con un ambiente somero y deltaico con altas tasas de aporte y pendientes inestables antes que un ambiente marino profundo, y sugieren una historia compleja de la evolución del relleno sedimentario que no se explica meramente con los esquemas basados exclusivamente en el contenido de foraminíferos que domina en la literatura.

    The qualitative and quantitative effect of initial conditions (linear and non-linear) and high Mach number (1.3 and 1.45) is studied on the turbulent mixing induced by the Richtmyer-Meshkov instability in idealized ICF conditions. The Richtmyer-Meshkov instability seeds Rayleigh-taylor instabilities in ICF experiments and is one of the factors that contributes to reduced performance of ICF experiments. Its also found in collapsing cores of stars and supersonic combustion. We use the Stony Brook University code, FronTier, which is verified via a code comparison study against the AMR multiphysics code FLASH, and validated against vertical shock tube experiments done by the LANL Extreme Fluids Team. These simulations are designed as a step towards simulating more realistic ICF conditions and quantifying the detrimental effects of mixing on the yield.

    2016-01-01

    BACKGROUND: Several Brazilian studies have addressed the International Classification of Functioning, Disability and Health (ICF), but few have analyzed the knowledge of the health professionals with regards to the ICF. OBJECTIVE: To verify whether the classification of the items in the Brazilian-Portuguese versions of The Shoulder Pain and Disability Index (SPADI) and The Disabilities Arm, Shoulder and Hand (DASH) questionnaires, obtained from health professionals who worked with patients having upper limb injuries, could be related to ICF components as defined by others studies. METHOD: There were 4 participants for the group "professionals with high familiarity of the ICF (PHF)" and 19 for the group of "professionals with some or no familiarity of the ICF (PSNF)". The participants judged whether the items on the two questionnaires belonged to the ICF body function, body structure or activity-participation component, and marked a confidence level for each trial using a numerical scale ranging from zero to 10. The items were classified by the discriminant content validity method using the Student'st-test and the Hochberg correction. The ratings were compared to the literature by the percentage of agreement and Kappa coefficient. RESULTS: The percentage of agreement of the rating from the PSNF and the PHF groups with the literature was equal to or greater than 77%. For the DASH, the agreement of the PSNF and PHF groups with the literature were, respectively, moderate (Kappa=0.46 to 0.48) and substantial (Kappa=0.62 to 0.70). CONCLUSIONS: Health professionals were able to correlate the three components of the ICF for most items on the 2 questionnaires, demonstrating some ease of understanding the ICF components. However, the relation of concept of pain with body function component is not clear for professional and deserves a more attentive approach. PMID:26786076

  3. Light intensity distribution calculation of curved surface diffraction patterns applied in ICF

    International Nuclear Information System (INIS)

    Conventional numerical methods of diffractive calculation are usually for the plane, and they are infeasible when the diffraction field applied in ICF is curved surface. In this paper, a method based on the idea of layering calculation, combining the algorithm of fast Fourier transform (FFT) with the technology of numerical fitting, has been proposed to calculate the light intensity distribution on the curved observation surface. This method can be applied to the surface with arbitrary shape, and it has comparatively high accuracy at fast calculation speed. The computation results show that the accuracy is improved as the layer number increases, and thus the method can effectively realize the light intensity distribution calculation of curved surface diffraction patterns applied in ICF.

  6. The ICF as a common language for rehabilitation goal-setting: comparing client and professional priorities

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Abstract Background Joint rehabilitation goals are an important component for effective teamwork in the rehabilitation field. The activities and participation domain of the ICF provides a common language for professionals when setting these goals. Involving clients in the formulation of rehabilitation goals is gaining momentum as part of a person-centred approach to rehabilitation. However, this is particularly difficult when clients have an acquired communication disability. The expressive communication difficulties negatively affect the consensus building process. As a result, obtaining information regarding rehabilitation goals from professionals and their clients warrants further investigation for this particular population. Methods This comparative study investigated clients and their assigned rehabilitation professionals' perception of the importance of ICF activities and participation domains for inclusion in their rehabilitation program. Twelve clients in an acute rehabilitation centre and twenty of their corresponding rehabilitation professionals participated in an activity using the Talking Mats™ visual framework for goal setting. Each participant rated the importance of the nine activities and participation domains of the ICF for inclusion in their current rehabilitation program. Results The ICF domains which consistently appear as very important across these groups are mobility, self-care and communication. Domains which consistently appear in the lower third of the rankings include spare time, learning and thinking and domestic life. Results indicate however that no statistical significant differences exist in terms of the individual domains across each of the participant groups. Within group differences however indicated that amongst the speech-language therapists and physiotherapists there was a statistical significant difference between spare time activities and communication and mobility. Conclusions Findings indicate that

    International Nuclear Information System (INIS)

    This analysis addresses the critical issue of the final transport of a heavy ion beam in an inertial confinement fusion reactor. The beam must traverse the reaction chamber from the final focusing lens to the target without being disrupted. This requirement has a strong impact on the reactor design. It is essential to the development of ICF fusion reactor technology, that the restrictions placed on the reactor engineering parameters by final beam transport consideration be understood early on

  15. Sistema automático para secagem de produtos agrícolas em camada fina = Automated system for thin-layer drying of agricultural products

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available Geralmente, o controle do processo de secagem em camada fina, é realizado com base na pesagem de amostras, retirando-se periodicamente a bandeja do secador e levando-a até uma balança, para determinar, por diferença de massa, a quantidade de água que foi retirada do produto durante o processo. Essa operação é a principal fonte de erro na determinação das taxas de secagem, tendo em vista a interrupção do processo de secagem ou a perda de parte da amostra durante a etapa de pesagem. Este trabalho propõe a automaçãodo controle da secagem em camada fina, utilizando-se um sistema baseado em uma célula de carga e em dispositivos eletrônicos endereçáveis. Os valores obtidos pelo monitoramento realizado pelo sistema proposto são armazenados e comparados com valores finais prédefinidos para o processo de secagem. Quando não houver diferença significativa entre os valores medidos e os pré-definidos, encerra-se o processo. O sistema proposto foi testado e validado, fornecendo uma série de resultados confiáveis, com elevada precisão e um excelente desempenho.Generally, the control of thin-layer grain drying is done based on weighing the samples, periodically removing the sample from the dryer and taking it to a precision scale in order to determine, by the difference in weight, the amount of water removed from the productduring the process. This operation is the main source of error in determining drying rates, due to the interruption of the drying process or the sample losses during the weighing stage. In this work, the automation of thin-layer grain drying control is proposed through the use of a system based on a load cell and on addressable electronic devices. The results are recorded in a file and compared with the final pre-defined values for the drying process. The process is terminated when there is no significant difference between the measured values and the pre-defined ones. The proposed system was tested and validated

    Full Text Available Fine litter dynamics within the canopy differ from litter dynamics on the forest floor for reasons such as differences in microclimate, substrate, disturbance level, stratum influence and decomposition rates. This study is the first attempt to quantify the fine litter accumulated in the canopy of Central Amazonian forests. We compared the canopy litter accumulation to fine litter-layer on forest floor and to other forests and also investigated which were the mostly accumulated litter omponents. We found that Central Amazonian Rainforest intercepts greater fine litter in the canopy (294 g.m-2 compared to other forest formations with higher winds speed as in a Costa Rican Cloud Forest (170 g.m-2. The mean canopy fine litter accumulated at the end of the dry season was less than a half of that on soil surface (833 g.m-2 and the fine wood component dominates the canopy samplings (174 g.m-2 while leafy component predominate on soil surface litter (353 g.m-2.A dinâmica da liteira fina no dossel difere da dinâmica no chão da floresta por razões como diferenças no microclima, tipo de substrato, taxas de decomposição, distúrbios e influência dos estratos. Esta é a primeira tentativa de quantificar a liteira fina acumulada no dossel das florestas da Amazônia Central. Comparamos o acúmulo da liteira no dossel com a camada de liteira do chão da floresta e com outros tipos de florestas e investigamos quais componentes da liteira acumularam em maiores quantidades. A floresta estudada na Amazônia Central interceptou uma maior quantidade de liteira no dossel (294 g.m-2 do que outras florestas com maior influência dos ventos, como na Costa Rica (170 g.m-2. A média de liteira no dossel no fim da estação seca foi menos da metade da acumulada sobre o solo (833 g.m-2. Os galhos finos dominaram nas amostras do dossel (174 g.m-2 enquanto as folhas predominaram na liteira sobre o solo (353 g.m-2.

    Full Text Available The metallurgical behavior of fine fractions of copper sulfide minerals of Compañía Minera Quebrada Blanca S.A. was studied by concentration through flotation in aqueous media modified by alcohol followed by bioleaching of the concentrates. By using a 1 % v/v of methanol, the metallurgical recovery of copper reaches 88 %, while the iron recovery was 43 %, the weight recovery was 18%, which indicates a high selectivity. These concentrates were then bioleached with and without nutrient medium, reaching 80 % of copper recovery after 10 and 17 days, respectively. Then, it is possible to conclude that this concentration-bioleaching metallurgical process is a promising route for copper recovery from the fine fraction of sulfide minerals.

    Se estudió la respuesta metalúrgica de la fracción fina, 100 % -100 # ASTM, de un mineral sulfurado de cobre de la Compañía Minera Quebrada Blanca S.A., sometido a una etapa de concentración mediante flotación en medio acuoso modificado (FEMAM® con metanol y la posterior biolixiviación agitada de este concentrado. Al emplear un 1 % v/v de metanol se logran los mejores resultados: una recuperación metalúrgica de cobre y hierro de 88 y 43 %, respectivamente, y una recuperación en peso del 18 %. Lo cual indica una alta selectividad de este tipo de flotación para especies sulfuradas de cobre. El concentrado FEMAM® fue posteriormente sometido a una etapa de biolixiviación agitada en ausencia y presencia del medio nutriente 9 K, lográndose el 80 % de extracción de cobre a los 17 y 10 días, respectivamente. Esto permite concluir que una ruta de concentración-biolixiviación es una alternativa tecnológica apropiada para procesar la fracción fina de minerales sulfurados de cobre.

    Full Text Available Mutations in the human DNA methyltransferase 3B (DNMT3B gene lead to ICF (immunodeficiency, centromeric region instability, facial anomalies syndrome type I. We have previously described a telomere-related phenotype in cells from these patients, involving severe hypomethylation of subtelomeric regions, abnormally short telomeres and high levels of telomeric-repeat-containing RNA (TERRA. Here we demonstrate that ICF-patient fibroblasts carry abnormally short telomeres at a low population doubling and enter senescence prematurely. Accordingly, we attempted to rescue the senescence phenotype by ectopic expression of human telomerase, which led to elongated telomeres with hypomethylated subtelomeres. The senescence phenotype was overcome under these conditions, thus dissociating subtelomeric-DNA hypomethylation per se from the senescence phenotype. In addition, we examined whether the subtelomeric methylation could be restored by expression of a normal copy of full length DNMT3B1 in ICF fibroblasts. Ectopic expression of DNMT3B1 failed to rescue the abnormal hypomethylation at subtelomeres. However, partial rescue of subtelomeric-hypomethylation was achieved by co-expression of DNMT3B1 together with DNA methyltransferase 3-like (DNMT3L, encoding a protein that functions as a stimulator of DNMT3A and DNMT3B. DNMT3B1 and DNMT3L are predominantly expressed during early embryonic development, suggesting that de novo subtelomeric DNA methylation during crucial stages of human embryonic development may be necessary for setting and maintaining normal telomere length.

  19. Integration of the Aurora KrF ICF laser system at Los Alamos

    International Nuclear Information System (INIS)

    The Aurora laser system, under construction at the Los Alamos National Laboratory for the past few years, is now being integrated into a working system for examining the applicability of high-power KrF lasers to inertial confinement fusion (ICF). The design principles of the system have been described in detail in earlier publications and conferences. Multikilojoule 248-nm 5-ns duration laser pulses, which have been derived from angular-multiplexed electron-beam-driven KrF amplifiers, are to be delivered to ICF targets when the system is fully integrated. The authors describe the progress of the Aurora system toward the goal of delivering energy (MkJ/48 pulses stacked into one 5-ns pulse/200-μm spot) to ICF targets. Integrated performance to date of the front end optical multiplexer/demultiplexer e-beam-driven amplifiers and alignment hardware are discussed in particular. They have concentrated on the demonstration of system integration at a modest (--100-J) level of energy on-target (without the final amplifier stage). They discuss the amplifier gain measurements, the extraction of energy from a chain of three e-beam-driven machines, and progress toward the delivery of on-target energy

It was found a positive relationship between the overall scores in the ICFES exam and academic performance in disciplinary subjects of the program. Moreover, specific relationships between the scores in the areas of language, mathematics and social sciences, and disciplinary subjects were found. For this reason, it is concluded that performance in these areas is a predictor of performance in disciplinary subjects.

    The collaborative research on ageing in Europe protocol was based on that of the World Health Organization Study on global AGEing and adult health (SAGE) project that investigated the relationship between health and well-being and provided a set of instruments that can be used across countries to monitor health and health-related outcomes of older populations as well as the strategies for addressing issues concerning the ageing process. To evaluate the degree to which SAGE protocol covered the spectrum of disability given the scope of the World Health Organization International Classification of Functioning, Disability and Health (ICF), a mapping exercise was performed with SAGE protocol. Results show that the SAGE protocol covers ICF domains in a non-uniform way, with environmental factors categories being underrepresented, whereas mental, cardiovascular, sensory functions and mobility were overrepresented. To overcome this partial coverage of ICF functioning categories, new assessment instruments have been developed. PRACTITIONER MESSAGE: Mapping exercises are valid procedures to understand the extent to which a survey protocol covers the spectrum of functioning. The mapping exercise with SAGE protocol shows that it provides only a partial representation of body functions and activities and participation domains, and the coverage of environmental factors is poor. New instruments are therefore needed for researchers to properly understand the health and disability of ageing populations.

    Full Text Available Hydrogenated amorphous silicon nitride (a:SiN:H films produced by CO2 and ArF laser-induced CVD in parallel configuration using silane/ammonia or disilane/ammonia gas mixtures were subjected to room temperature multiple pulse ArF excimer laser irradiations in an inert gas atmosphere. Modifications in their chemical composition, refractive index, and surface morphology were systematically followed up through Fourier-transform infrared spectroscopy (FTIR, energy dispersive X-ray spectroscopy (EDS, single wavelength ellipsometry and atomic force microscopy (AFM, respectively. The observed film modifications involving large reductions in hydrogen (Si-H and N-H with the first few shots accompanied by a progressive incorporation of oxygen (Si-O and Si-OH and a reduction of Si-N bonds that are attributed to UV-induced photochemistry where the atmospheric water incorporated in the films between successive irradiations plays an important role. Comparison among the different films indicated that the extent of bonded hydrogen in the films and their surface morphology influence their oxidation resistance.

    Full Text Available The formulas based on the elasticity theory are widely used for the calculation of foundation settlements, as the geotechnical regulations recommends their use. However, these methods do not cover all possible geotechnical situations because, frequently, the geotechnical conditions are complex. In this work, the influence of an inclined rigid layer on the elastic settlements of a shallow foundation is analysed. For this purpose, 273 three-dimensional non-linear finite element models have been solved varying the key parameters of the problem: inclination and depth of the rigid layer and the rigidity of the foundation. Finally, a statistical analysis of the results of the models has been performed and a formula, which can be used for the calculation of the settlements to consider the presence of a rigid inclined layer in depth, has been proposed.Las fórmulas basadas en la teoría de la elasticidad son ampliamente utilizadas para el cálculo de asientos de cimentaciones, ya que la totalidad de la normativa geotécnica recomienda su empleo. No obstante, estos métodos no cubren todas las situaciones geotécnicamente posibles ya que frecuentemente las condiciones geológicas son complejas. En este trabajo se analiza la influencia de la presencia de una capa rígida inclinada en los asientos elásticos de una cimentación superficial. Para ello se han resuelto 273 modelos tridimensionales no lineales de elementos finitos, variando los parámetros clave del problema: la inclinación y la profundidad de la capa rígida y la rigidez de la cimentación. Finalmente, se ha realizado un análisis estadístico de los resultados de los modelos y se ha propuesto una fórmula que puede ser utilizada en el cálculo de asientos por métodos elásticos, para tener en consideración la presencia de una capa rígida inclinada en profundidad.

    Elastic waves provide characteristics of earth interior, which are necessary in Hydrocarbon and mineral prospect ions. This information is affected by shallow layers distorting the data coming from deep layers. In the colombian geology are fragment shallow layer with high velocity. In this case waves travel by anomalous paths being difficult to identity them, because these events contaminate and alternate the information considerated usefull. The effects associated to this phenomena are unknown with details. In this paper, one of these case is presented througen seismic modeling and vial data with an interpretation about its characteristics.

Esta información es afectada generalmente por las capas someras, cuyas características distorsionan los datos provenientes de las capas de interés, usual mente más profundas. Un caso, frecuente en la geología colombiana es el de las capas someras de alta velocidad. En este caso las ondas siguen direcciones anómalas, y con frecuencia la información es muy difícil de identificar, ya que se generan eventos que la contaminan y probablemente la atenúan, Aunque se sabe que existe este efecto, muchos de sus detalles son desconocidos.

    The Immunodeficiency, Centromeric instability, Facial anomalies (ICF) syndrome is an autosomal recessive disease presenting with immunodeficiency secondary to hypo- or agammaglobulinemia, developmental delay, and facial anomalies. Centromeric instability is the cytogenetic hallmark of the disorder which results from targeted chromosomal rearrangements related to a genomic methylation defect. We describe a patient carrying a homozygous mutation of the ZBTB24 gene, which has been recently shown to be responsible for ICF syndrome type 2. Our patient presented with intellectual disability, multiple café-au-lait spots, and a large cerebral arachnoidal cyst. Although laboratory signs of impaired immune function, such as reduced serum IgM were detected, our patient did not present clinical manifestations of immunodeficiency. Brain malformations have not been reported so far in ICF syndrome and it can be speculated that ZBTB24 mutations may alter cerebral development. Nevertheless, we cannot rule out that the presence of the cerebral cyst in the patient is coincidental. In summary, our patient illustrates that clinical evidence of immunodeficiency is not a universal feature of ICF2 syndrome type 2 and suggests that brain malformations may be present in other ICF cases.

    2007-05-01

    An important basis for the successful development of rehabilitation practice and research is a conceptually sound description of rehabilitation understood as a health strategy based on a universally accepted conceptual model and taxonomy of human functioning. With the approval of the International Classification of Functioning, Disability and Health (ICF) by the World Health Assembly in 2001 and the reference to the ICF in the World Health Assembly's resolution on "Disability, including prevention, management and rehabilitation" in 2005, we can now rely on a universally accepted conceptual model. It is thus time to initiate the process of evolving an ICF-based conceptual description that can serve as a basis for similar conceptual descriptions and according definitions of the professions applying the rehabilitation strategy and of distinct scientific fields of human functioning and rehabilitation research. In co-operation with the Physical and Rehabilitation Medicine (PRM) section of the European Union of Medical Specialists (UEMS) and its professional practice committee, we present a first tentative version of an ICF-based conceptual description in this paper. A brief definition describes rehabilitation as the health strategy applied by PRM and professionals in the health sector and across other sectors that aims to enable people with health conditions experiencing or likely to experience disability to achieve and maintain optimal functioning in interaction with the environment. Readers of the Journal of Rehabilitation Medicine are invited to contribute towards achieving an internationally accepted ICF-based conceptual description of rehabilitation by submitting commentaries to the Editor of this journal.

Estas propiedades incluyen el espesor de la capa delgada como así también las velocidades de las ondas compresionales y de corte, y las densidades de cada uno de los tres medios. Se presentan numerosos ejemplos utilizando datos sintéticos con ruido gaussiano generados a partir de diversos modelos de capas delgadas representativos de reservorios de gas de unos pocos metros de espesor.

  19. Possibilities and Implications of Using the ICF and Other Vocabulary Standards in Electronic Health Records.

    2015-12-01

    There is now widespread recognition of the powerful potential of electronic health record (EHR) systems to improve the health-care delivery system. The benefits of EHRs grow even larger when the health data within their purview are seamlessly shared, aggregated and processed across different providers, settings and institutions. Yet, the plethora of idiosyncratic conventions for identifying the same clinical content in different information systems is a fundamental barrier to fully leveraging the potential of EHRs. Only by adopting vocabulary standards that provide the lingua franca across these local dialects can computers efficiently move, aggregate and use health data for decision support, outcomes management, quality reporting, research and many other purposes. In this regard, the International Classification of Functioning, Disability, and Health (ICF) is an important standard for physiotherapists because it provides a framework and standard language for describing health and health-related states. However, physiotherapists and other health-care professionals capture a wide range of data such as patient histories, clinical findings, tests and measurements, procedures, and so on, for which other vocabulary standards such as Logical Observation Identifiers Names and Codes and Systematized Nomenclature Of Medicine Clinical Terms are crucial for interoperable communication between different electronic systems. In this paper, we describe how the ICF and other internationally accepted vocabulary standards could advance physiotherapy practise and research by enabling data sharing and reuse by EHRs. We highlight how these different vocabulary standards fit together within a comprehensive record system, and how EHRs can make use of them, with a particular focus on enhancing decision-making. By incorporating the ICF and other internationally accepted vocabulary standards into our clinical information systems, physiotherapists will be able to leverage the potent

    Fast ignition(FI) concept of ICF is one of the most attractive application of high intensity ultrashort laser. The UV light has some advantages for applying to fast ignition, the first, as the I λ2 scaling law of hot electron temperature, at the FI required intensity(1020 W/cm2), the long wavelength light will generate >10 MeV electron that can not deposit energy efficiently in the fuel region. Meanwhile the UV light can just generate the electron with the required energy of 1 MeV.

    International Nuclear Information System (INIS)

    The SAFIRE (Systems Analysis for ICF Reactor Economics) code incorporates analytical models for scaling the cost and performance of several inertial confinement fusion reactor concepts for electric power. The code allows us to vary design parameters (e.g., driver energy, chamber pulse rate, net electric power) and evaluate the resulting change in capital cost of power plant and the busbar cost of electricity. The SAFIRE code can be used to identify the most attractive operating space and to identify those design parameters with the greatest leverage for improving the economics of inertial confinement fusion electric power plants

    Simple expressions for the cost and efficiency of repetitively-pulsed angularly multiplexed KrF laser fusion drivers have been developed for commercial-applications studies. These simple expressions summarize estimates obtained from detailed cost/performance studies incorporating recent results of ongoing physics, design, and cost studies. Contributions of KrF laser capital charges and O and M costs to total levelized constant-dollar (1984) unit ICF power generation cost are estimated as a function of plant size and driver pulse energy using a published gain for short-wavelength lasers and representative values of plant parameters

  3. Status of Indirect Drive ICF Experiments on the National Ignition Facility

    International Nuclear Information System (INIS)

    In the quest to demonstrate Inertial Confinement Fusion (ICF) ignition of deuterium-tritium (DT) filled capsules and propagating thermonuclear burn with net energy gain (fusion energy/laser energy >1), recent experiments on the National Ignition Facility (NIF) have shown progress towards increasing capsule hot spot temperature (Tion>5 keV) and fusion neutron yield (~1016), while achieving ~2x yield amplification by alpha particle deposition. At the same time a performance cliff was reached, resulting in lower fusion yields than expected as the implosion velocity was increased. Ongoing studies of the hohlraum and capsule physics are attempting to disseminate possible causes for this performance ceiling.

    Hohlraums (measuring 6-mm in diameter by 7-mm in height) have been heated by x-rays from a z-pinch. Over measured x-ray input powers P of 0.7 to 13 TW, the hohlraum radiation temperature T increases from approximately55 to approximately130 eV, and is in agreement with the Planckian relation P-T4. The results suggest that indirect-drive ICF studies involving NIF relevant pulse shapes and <2-mm diameter capsules can he studied using this arrangement

    Performance trends in elite freestyle swimmers are well known, but not for master freestyle swimmers. We investigated trends in participation, performance, and sex difference in performance of 65,584 freestyle master swimmers from 25-29 to 85-89 years competing in FINA World Masters Championships between 1986 and 2014. The men-to-women ratio was calculated for each age group, and the trend across age groups was analyzed using single linear regression analysis. Trends in performance changes were investigated using a mixed-effects regression model with sex, distance, and calendar year as fixed variables. Participation increased in women and men in older age groups (i.e., 40 years and older). Women and men improved race times across years in all age groups and distances. For age groups 25-29 to 75-79 years, women were slower than men, but not for age groups 80-84 to 85-89 years. In 50, 100, and 200 m, women reduced the sex difference from 1986 to 2014 in age groups 30-34 to 75-79 years. In 400 m, women reduced the gap to men across time in age groups 40-44, 45-49, and 55-59 years. In 800 m, sex difference became reduced across time in age groups 55-59 and 70-74 years. In summary, participation increased from 1986 to 2014 in women and men in older age groups, women and men improved across time performance in all distances, and women were not slower compared to men in age groups 80-84 to 85-89 years. We expect a continuous trend in increasing participation and improved performance in master freestyle swimmers. PMID:26833033

    In the present paper, the defects of dew point method for measuring the mass of gas filled in ICF shells are analyzed. An accurate state equation for gas D2 is deduced from Benedict-Webb-Rubin (BWR) equation and experimental data in planar phase. A direct method to determine gas mass in ICF shells via measuring the temperature and pressure outside the shells and solving the equation of state by numerical method is proposed. It overcomes the theoretical defects of dew point method and the complexities of equipment. In the present method, the state equation can be improved by more accurately measuring P-V-T values of gas D2, so the measuring precision of the mass of gas in the shells can also be improved. The present method is effective for treating mix gases filled in the shells as well. The errors between the computational results and experimental data are very small. Some cases in the filling process are predicted, and the proper temperature and pressure for filling gases effectively are also suggested.

  13. Recent progress on the Los Alamos Aurora ICF [inertial confinement fusion] laser system

    International Nuclear Information System (INIS)

    Aurora is the Los Alamos short-pulse, high-power, krypton-fluoride laser system. It serves as an end-to-end technology demonstration prototype for large-scale ultraviolet laser systems for short wavelength inertial confinement fusion (ICF) investigations. The system is designed to employ optical angular multiplexing and serial amplification by electron-beam-driven KrF laser amplifiers to deliver stacked, 248-nm, 5-ns duration multikilojoule laser pulses to ICF-relevant targets. This paper presents a summary of the Aurora system and a discussion of the progress achieved in the construction and integration of the laser system. We concentrate on the main features of the following major system components: front-end lasers, amplifier train, multiplexer, optical relay train, demultiplexer, and the associated optical alignment system. During the past year, two major construction and integration tasks have been accomplished. The first task is the demonstration of 96-beam multiplexing and amplified energy extraction, as evidenced by the integrated operation of the front end, the multiplexer (12-fold and 8-fold encoders), the optical relay train, and three electron-beam-driven amplifiers. The second task is the assembly and installation of the demultiplexer optical hardware, which consists of over 300 optical components ranging in size from several centimeters square to over a meter square. 13 refs., 13 figs

    International Nuclear Information System (INIS)

    The National Ignition Facility Project The mission of the National Ignition Facility (NIF) is to produce ignition and modest energy gain in inertial confinement fusion (ICF) targets. Achieving these goals will maintain U.S. world leadership in ICF and will directly benefit the U.S. Department of Energy (DOE) missions in national security, science and technology, energy resources, and industrial competitiveness. Development and operation of the NIF are consistent with DOE goals for environmental quality, openness to the community, and nuclear nonproliferation and arms control. Although the primary mission of inertial fusion is for defense applications, inertial fusion research will provide critical information for the development of inertial fusion energy. The NIF, under construction at Lawrence Livermore National Laboratory (LLNL), is a cornerstone of the DOE's science-based Stockpile Stewardship Program for addressing high-energy-density physics issues in the absence of nuclear weapons testing. In pursuit of this mission, the DOE's Defense Programs has developed a state-of-the-art capability with the NIF to investigate high-energy-density physics in the laboratory with a microfusion capability for defense and energy applications. As a Strategic System Acquisition, the NIF Project has a separate and disciplined reporting chain to DOE as shown below

    1998-09-08

    This issue of the ICF Quarterly Report focuses on the final section of the 192-arm, 1.8-MJ National Ignition Facility (NIF). We describe both technological advances necessary for optimal utilization of the delivered energy and the hohlraum physics resulting from extremely high energy densities. Two articles belong to the first category. The conversion of infrared light to ultraviolet occurs at the tripler in the NIF's Final Optics Assembly. It is then necessary to separate any unconverted (first- and second-harmonic) light from the tripled-frequency light passed to the target. Large-Aperture Color-Separation Gratings for Diverting Unconverted Light Away from the NIF Target describes the design and fabrication of novel diffraction gratings that fulfill this function. In both direct- and indirect-drive ICF, the symmetry of the capsule as it compresses is crucial. The NIF will have 48 clusters of four beams incident on targets. Optimization of Beam Angles for the National Ignition Facility (p. 15) presents the rationale used to assign beam angles for cylindrical indirect drive while still allowing direct-drive and tetrahedral indirect-drive experiments to be performed.

    In 1972, I joined the Livermore ICF Theory and Target Design group led by John Nuckolls, shortly after publication of John's seminal Nature article on ICF. My primary role, working with others in the target design program including Mordy Rosen, Steve Haan, and Larry Suter, has been as a target designer and theorist who utilized the LASNEX code to perform numerical experiments, which along with analysis of laboratory and underground thermonuclear experiments allowed me to develop a series of models and physical insights which have been used to set the direction and priorities of the Livermore program. I have had the good fortune of working with an outstanding team of scientists who have established LLNL as the premier ICF laboratory in the world. John Emmett and the LLNL Laser Science team were responsible for developing a series of lasers from Janus to Nova which have given LLNL unequaled facilities. George Zimmerman and the LASNEX group developed the numerical models essential for projecting future performance and requirements as well as for designing and analyzing the experiments. Bill Kruer, Bruce Langdon and others in the plasma theory group developed the fundamental understanding of laser plasma interactions which have played such an important role in ICF. And a series of experiment program leaders including Mike Campbell and Joe Kilkenny and their laser experimental teams developed the experimental techniques and diagnostic capabilities which have allowed us to c increasingly complex and sophisticated experiments

The internal construct validities of "Body Functions-Body structures" (BF-BS, "Activity" (A, "Participation" (P and "Environmental Factors" (EF domains were tested by Rasch analysis and reliability by internal consistency and person separation index (PSI. External construct validity was evaluated by correlating the Rasch transformed scores with SF-36 and WOMAC. Results In each scale, some items showing disordered thresholds were rescored, testlets were created to overcome the problem of local dependency and items that did not fit to the Rasch model were deleted. The internal construct validity of the four scales (BF-BS 16 items, A 8 items, P 7 items, EF 13 items were good [mean item fit (SD 0.138 (0.921, 0.216 (1.237, 0.759 (0.986 and -0.079 (2.200; person item fit (SD -0.147 (0.652, -0.241 (0.894, -0.310 (1.187 and -0.491 (1.173 respectively], indicating a single underlying construct for each scale.

  9. Recent Measurements of DT Gamma to Neutron Branching Ratio at ICF Conditions

    2011-10-01

    The total T(d,g)5He/T(d,n)4He branching ratio of (4.5 +/- 0.5)E-5 has been measured on Inertial Confinement Fusion (ICF) implosions at the OMEGA laser facility. Recent measurements have shown that the DT branching ratio at ICF is 2 - 3 times less than that of previously measured at particle accelerator facilities. Measurements were done at ion temperatures of (5 +/- 2) keV, which is quite low compared to previous measurements. Implication of the recent founding is that nuclear properties such as DT branching ratio might be reconsidered at low temperature ICF and stellar conditions. In practical sense, precise measurements of the branching ratio T(d,g)5He relative to T(d,n)4He are important in order to diagnose target areal density and resultant fusion yield of cryogenically-layered implosions at the National Ignition Facility (NIF). In this work, we have used LANL's Gas Cherenkov Detector (GCD), which provides a high bandwidth, energy thresholding capability for gamma-ray detection using gamma/electron/Cherenkov conversion. High-bandwidth aids the detection of D-T fusion gamma rays before the arrival of associated 14.1 MeV neutron-induced gammas; energy thresholding gives further protection against such undesirable backgrounds. In addition, to reduce systematic uncertainty, we have applied three independent calibration methods to characterize GCD response such as (1) D-3He gamma-rays generated at Omega laser where no absolute detector calibration was required because quite similar gamma spectrum from D3He and DT, (2) mono-energetic gamma rays generated at Duke University's High Intensity Gamma-ray Source (HIgS), and (3) 14-MeV neutron-induced inelastic gamma-rays generated at OMEGA using puck materials of known areal density placed near target center. In conjunction with an independent neutron yield measurements and ACCEPT and GEANT4 simulation codes, the resultant DT branching ratio was inferred. This work was performed by Los Alamos National Laboratory under the

Of the 51 EDAD items analysed, 29 were backcoded to specific d2-d7 domains of the ICF Checklist and, by rating the recorded difficulty to perform specific tasks with or without help, these were then taken as performance and capacity respectively. A global ICF score was also derived, albeit lacking data for d1, "Learning and applying knowledge", d8, "Major Life Areas" and d9, "Community, Social and Civic Life". Data were grouped by sex, age, residence and initial positive screening, and prevalence figures were calculated by disability level both for the general population, using the originally designed weights, and for the population that had screened positive to disability.

    This study evaluates whether the International Classification of Functioning, Disability, and Health (ICF) framework provides a useful basis to ensure that key user needs are identified in the development of a home-based arm rehabilitation system for stroke patients. Using a qualitative approach, nine people with residual arm weakness after stroke and six healthcare professionals with expertise in stroke rehabilitation were enrolled in the user-centered design process. They were asked, through semi-structured interviews, to define the needs and specification for a potential home-based rehabilitation device to facilitate self-managed arm exercise. The topic list for the interviews was derived by brainstorming ideas within the clinical and engineering multidisciplinary research team based on previous experience and existing literature in user-centered design. Meaningful concepts were extracted from questions and responses of these interviews. These concepts obtained were matched to the categories within the ICF comprehensive core set for stroke using ICF linking rules. Most of the concepts extracted from the interviews matched to the existing ICF Core Set categories. Person factors like gender, age, interest, compliance, motivation, choice, and convenience that might determine device usability are yet to be categorized within the ICF comprehensive core set. The results suggest that the categories of the comprehensive ICF Core Set for stroke provide a useful basis for structuring interviews to identify most users needs. However some personal factors (related to end users and healthcare professionals) need to be considered in addition to the ICF categories. PMID:26131797

    The International Classification of Functioning, Disability and Health (ICF) framework facilitates systematic assessment of functioning across four components. ICF Core Sets are proposed to be beneficial for clinicians in multidisciplinary care settings because they provide a common language for communication. A clinical vignette of a postmenopausal woman with rheumatoid arthritis (RA) and a non-traumatic vertebral fracture is presented to discuss how the ICF Core Sets for RA and osteoporosis (OP) can be helpful in structuring clinical decisions. To demonstrate how condition-specific ICF Core Sets can be used to evaluate and treat women with two comorbidities, each component of the ICF Core Sets is compared across conditions and integrated into clinical decision-making. Topics covered include: exercise tolerance, urinary continence, bone mass, fear of falling, and environmental factors. The benefits of thorough communication with the client and a common language across healthcare disciplines are highlighted as the potential benefits of the ICF framework; however, limitations to uptake of the ICF in clinical practice are also addressed.

    For an inertial confinement fusion (ICF) system, the light intensity distribution in the hohlraum is key to the initial plasma excitation and later laser-plasma interaction process. Based on the concept of coordinate transformation of spatial points and vector, we present a robust method with a detailed procedure that makes the calculation of the three dimensional (3D) light intensity distribution in hohlraum easily. The method is intuitive but powerful enough to solve the complex cases of random number of laser beams with arbitrary polarization states and incidence angles. Its application is exemplified in the Shenguang III Facility (SG-III) that verifies its effectiveness and it is useful for guiding the design of hohlraum structure parameter.

    International Nuclear Information System (INIS)

    Simple expressions suitable for use in commercial-applications plant parameter studies for the direct capital cost plus indirect field costs and for the efficiency as a function of repetition rate were developed for pure-optical-compression KrF laser fusion drivers. These simple expressions summarize estimates obtained from detailed cost-performance studies incorporating recent results of ongoing physics, design, and cost studies. Contributions of KrF laser capital charges and D and M costs to total levelized constant-dollar (1984) unit ICF power generation cost are estimated as a function of plant size and driver pulse energy using a published gain for short-wavelength lasers and representative values of plant parameters

    In the quest to demonstrate Inertial Confinement Fusion (ICF) ignition of deuterium-tritium (DT) filled capsules and propagating thermonuclear burn with net energy gain (fusion energy/laser energy >1), recent experiments on the National Ignition Facility (NIF) have shown progress towards increasing capsule hot spot temperature (Tion>5 keV) and fusion neutron yield (~1016), while achieving ~2x yield amplification by alpha particle deposition. At the same time a performance cliff was reached, resulting in lower fusion yields than expected as the implosion velocity was increased. Ongoing studies of the hohlraum and capsule physics are attempting to disseminate possible causes for this performance ceiling.

    We introduce wavelets, curvelets and multiresolution analysis techniques to assess the symmetry of X ray driven imploding shells in ICF targets. After denoising X ray backlighting produced images, we determine the Shell Thickness Averaged Radius (STAR) of maximum density, r*(N, {\\theta}), where N is the percentage of the shell thickness over which to average. The non-uniformities of r*(N, {\\theta}) are quantified by a Legendre polynomial decomposition in angle, {\\theta}. Undecimated wavelet decompositions outperform decimated ones in denoising and both are surpassed by the curvelet transform. In each case, hard thresholding based on noise modeling is used. We have also applied combined wavelet and curvelet filter techniques with variational minimization as a way to select the significant coefficients. Gains are minimal over curvelets alone in the images we have analyzed.

  19. Recent advances in direct-drive ICF target physics at the laboratory for laser energetics

    International Nuclear Information System (INIS)

    The principal role of the Laboratory for Laser Energetics (LLE) is the development and validation of the direct-drive approach to inertial fusion. The LLE experimental and theoretical programs in support of this mission were organized to provide a moderate-gain option for the U.S. National Ignition Facility (NIF). Experimental implementation of the LLE program is carried out on the LLE's 30-kJ, 60-beam, UV OMEGA laser. This paper summarizes the status of the direct-drive ICF physics program at LLE with emphasis on the development of beam-smoothing techniques, long-scale-length plasma interaction experiments, direct-drive planar-foil hydrodynamic instability experiments, the effect of laser nonuniformity on target stability, integrated spherical target implosion experiments, design of direct-drive targets, development of target diagnostic techniques, and implementation of cryogenic-fuel-layering technology.

  20. Using gamma-ray emission to measure areal density of ICF capsules

    Fusion neutrons streaming from a burning ICF capsule generate gamma rays via nuclear inelastic scattering in the ablator of the capsule. The intensity of gamma-ray emission is proportional to the product of the ablator areal density ('{rho}R') and the yield of fusion neutrons, so by detecting the gamma rays we can infer the ablator areal density, provided we also have a measurement of the capsule's total neutron yield. In plastic-shell capsules, for example, {sup 12}C nuclei emit gamma rays at 4.44 MeV after excitation by 14.1-MeV neutrons from D+T fusion. These gamma rays can be measured by the Gamma Reaction History (GRH) experiment being built at the National Ignition Facility (NIF). A linear error analysis indicates the chief sources of uncertainty in inferred areal density.

    ICF power plants, such as the LIFE scheme at LLNL, may employ a high-Z, target-chamber gas-fill to moderate the first-wall heat-pulse due to x-rays and energetic ions released during target detonation. To reduce the uncertainties of cooling and beam/target propagation through such gas-filled chambers, we present a pulsed plasma source producing 2-5 eV plasma comprised of high-Z gases. We use a 5-kJ, 100-ns theta discharge for high peak plasma-heating-power, an electrode-less discharge for minimizing impurities, and unobstructed axial access for diagnostics and beam (and/or target) propagation studies. We will report on the plasma source requirements, design process, and the system design.

    Em 06 de junho de 2000 (~15: 00-17: 00 UT), o Brazilian Solar Spectroscope (BSS) registrou uma explosão solar intensa no intervalo de freqüência de (1000-2000) MHz, com alta resolução temporal (100 ms) e espectral (5 MHz). A atividade solar relacionada a esta explosão associada à região ativa (AR) 9026 e classificada como X2.3 foi grande. O Ondrejov Observatory registrou rádio emissões até 4,5 GHz. O satélite SOHO registrou uma série de erupções solares, incluindo uma Ejeção de Massa Coronal (CME) tipo "full-halo" (~15: 54 UT). Explosões tipo II/IV também foram registradas. Na faixa de ondas decimétricas, este evento apresentou dois picos distintos (~15: 21 UT e ~16: 42 UT). O primeiro pico coincide com a explosão registrada em raios-X moles (GOES) e em raios-X duros (Yohkoh). Os espectros dinâmicos com alta resolução do BSS revelaram várias estruturas finas, principalmente emissões tipo "zebra" e "fibra", rádio pulsações, emissões tipo III e do único caso de emissões "zebra" harmônicas observado na faixa decimétrica. Neste trabalho, analisamos a evolução temporal e o comportamento global do evento de 06 de junho de 2000, com ênfase na identificação e associação da ocorrência de cada tipo de estrutura fina registrada em rádio com cada etapa da explosão. Resultados preliminares mostraram que, na fase pré-flare, as estruturas finas apresentaram taxa de deriva negativa (~ 70-190 MHz/s). As emissões tipo "zebra" concentram-se na fase de descida do primeiro pico impulsivo e na de subida do segundo pico. Enquanto que as emissões tipo "fibra" ocorrem em ambas fases, mas preferivelmente durante a fase de descida. Os resultados serão apresentados e discutidos.

Se realizó el aislamiento e identificación genérica de la microbiota bacteriana y se determinó el contenido de nicotina y el pH de las hojas de tabaco para cada estrato foliar. Las poblaciones de Bacillus en todos los estratos foliares siempre fueron superiores a otros géneros aislados como Staphylococcus y Arthrobacter . Desde los niveles foliares inferiores hasta los superiores el contenido de nicotina se incrementó significativamente, el pH mostró una ligera disminución (no significativa p<0,01 y disminuyó la densidad poblacional de bacterias de todos los géneros aislados. El modelo de regresión reveló que la disminución de la densidad poblacional de los géneros bacterianos que se aprecia al ascender por los diferentes niveles foliares estuvo más relacionada con el incremento de la concentración de nicotina en las hojas que con la variación del pH.

    The National Ignition Facility (NIF) is under construction at LLNL for the Department of Energy Stockpile Stewardship Program. It will be used for experiments for Inertial Confinement Fusion (ICF) Ignition, High Energy Density (HED) science, and basic science. Many issues confront experimentalists who wish to design, fabricate, and install diagnostics on the NIF. To foster this process the ICF and HED programs at LLNL have formed a diagnostic research and development group to look at issues outside the charter of facility diagnostics (core diagnostics). We will present data from instrumentation and associated technology that is being developed by this group. A major portion of our instrumentation work is on improvements for readout systems. We have several efforts related to CCD device development. Work has been done in collaboration with the University of Arizona to backthin a large format CCD device (36mm{sup 2}). This work has shown good results. The device has very high quantum efficiency, low noise readout and high charge transfer efficiency. The device is being fielded in direct optical, direct x-ray and 13-15 RV electron readout applications. In addition to readout device development we have completed work on a CCD readout system. With a commercial vendor we have developed a large format, compact, Ethernet addressable CCD camera system. This system fits in shoebox size volume, is thermal electrically cooled, supports a variety of CCD devices and can be run from remote locations via TCP/IP protocol. We are also doing work to improve streak camera systems. We have coupled our large format CCD system to an MK2 Kentech streak tube. Improvements have been made to the resolution and dynamic range of the system. Similar improvements have been made to the LLNL optical streak camera systems. We will present data from the optical and x-ray streak camera work. In addition we will present data from single shot high-speed, high dynamic range data link work. In

    Balance impairment is a common manifestation in older people with COPD and may contribute to overall functional decline; however, the relationship between balance and global functioning has not been studied. This study aimed to explore the global functioning of COPD patients with and without functional balance impairment. Functional balance was assessed with the Timed Up-and-Go (TUG) test and global functioning with the Comprehensive ICF Core Set for Obstructive Pulmonary Diseases. Participants (n = 134) were divided in 2 groups according to their performance in TUG (with and without balance impairment) and the ICF Core Set results were compared between groups. Fifty-four (40.3%) participants had functional balance impairment. The groups presented a similar extent of problems in several categories of the ICF components. However, participants with balance impairment were more severely affected (p social life, and a more negative perception of Environmental factors related to products and technology of buildings for private use and social support services (p balance impairment have more functional problems and are more severely restricted in daily life than patients without compromised balance. Understanding the relationship between balance control and global functioning will contribute to guide interventions aimed at maintaining functioning and minimizing disability.

    The ICF Programs in China have made significant progress in solid state laser technology development and advanced laser facility designing with multilabs' efforts in the past years. The eight-beam SG-II laser facility is expected to complete for a 4.8-kJ output at 1.05 micrometers and to operate for target experiments in a few months. A national project, SG-II laser facility, has been proposed to produce 60-kJ blue light for target physics experiments and is being conceptually designed. New laser technologies, including multipass amplification, large aperture plasma electrode switches, fast growth of KDP, laser glass with fewer platinum grains, long flash lamps and precision manufacturing of large optical components are being developed to meet the requirements of the SG-III Project. In addition, numerical simulations are being conducted for the optical design of the new facility. The Technical Integration Line of 4 by 2 segmented array as a prototype module of SG-II with a chamber for laser beams measurements will be first built in the next few years.

    International Nuclear Information System (INIS)

    A design study is underway to define the optimal architecture for a KrF laser system which will deliver 10 MJ of 248-nm light to an ICF target. The authors present one approach which incorporates final power amplifiers in the megajoule class, achieving 10 MJ with only four final amplifiers. Each double-pass laser amplifier employs two-sided electron-beam pumping of the laser gas medium. Analysis of the design is based on a Monte-Carlo electron-beam deposition code, a one-dimensional, time-dependent kinetics code, and pulsed power circuit modeling. Linear dimensions of the amplifier's extracted gain volume are 6.25 m in height and length and 5.12 m in width. Each amplifier handles 160 angularly multiplexed laser channels. The one-amagat, krypton-rich laser medium is e-beam pumped at 60 kW cm/sup -3/ (4 MA at 3.3 MV) over the 2-microsecond duration of the laser beam pulse train

  20. Improved performance of the Aurora KrF/ICF laser system

    International Nuclear Information System (INIS)

    This paper reports on Aurora the Los Alamos National Laboratory short pulse high power krypton-fluoride laser system. It serves as an end-to-end technology demonstration prototype for large scale UV laser systems for short wavelength inertial confinement fusion (ICF) research. The system employs optical angular multiplexing and serial amplification by electron-beam driven KrF laser amplifiers. The 1-5-ns pulse of the Aurora front end is split into ninety-six beams which are angularly and temporally multiplexed to produce a 480-ns pulse train for amplification by four KrF laser amplifiers. The largest amplifier, the large aperture module (LAM), has a 1-m square aperture and a gain length of 2 m. In the present system configuration half (forty-eight) of the amplified pulses are demultiplexed using different optical path lengths and delivered simultaneously to target. The system has not been optimized, and several near term improvements are expected to result in significant increases in both delivered energy and target irradiance. Removing the twelve calorimeters from the lens plate and allowing forty-eight beams to go to target will increase delivered energy by 33%. Relatively minor modifications to the front end should result in a 30% increase in system output energy. Replacement of damaged optics will increase transmission into the preamplifier by at least 25%. New optics and reduction of retro-pulses will allow the preamplifier stage gain to be increased by 50%

    The first measurements of hydrodynamic instability growth at the fuel-ablator interface in an ICF implosion are reported. Previous instability measurements on the National Ignition Facility have used plastic capsules to measure ablation front Rayleigh-Taylor growth with the Hydro.-Growth Radiography (HGR) platform. These capsules substituted an additional thickness of plastic ablator material in place of the cryogenic layer of Deuterium- Tritium (DT) fuel. The present experiments are the first to include a DT ice layer, which enables measurements of the instability growth occurring at the fuel-ablator interface. Instability growth at the fuel-ablator interface is seeded differently in two independent NIF experiments. In the first case, a perturbation on the outside of the capsule feeds through and grows on the interface. Comparisons to an implosion without a fuel layer produce a measure of the fuel's modulation. In the second case, a modulation was directly machined on the inner ablator before the fuel layer was added. The measurement of growth in these two scenarios are compared to 2D rad-hydro modeling.

We will also discuss the results of a major effort to increase the shot rate on NIF. An extensive set of projects, developed in conjunction with the HED community and drawing on best practices at other facilities, improved shot rate by over 80% and recently enabled us to deliver 356 target experiments in FY15 in support of the users. Through an updated experimental set-up and review process, computer controlled set-up of the laser and diagnostics and disciplined operations, NIF also continued to deliver experimental reliability, precision and repeatability. New and complex platforms are introduced with a high success rate. Finally we discuss how new capabilities and further efficiency improvements will enable the successful execution of ICF and HED experimental programs required to support the quest for Ignition and the broader Science Based Stockpile Stewardship mission

    The PRP generally endorsed the Program plan during the short time for discussions. We agree that the strategy to develop a hohlraum that is symmetric and has low laser-plasma instabilities and to develop an alternative method for supporting the capsule is the best path forward for making progress in understanding ignition performance. The Program is oriented toward a milestone in 2020 for “determining the efficacy of NIF for ignition and credible physics-scaling to multi-megajoule yields for all ICF approaches.” We are concerned that the time and resources are not sufficient to vet all of the various approaches that are being pursued to make an informed decision by this date. For NIF to meet this goal, a process will be needed to to select the most promising paths forward. We recommend that the Program develop this process for selecting the path forward to optimize resources. We were glad to see that the direct drive program took our comments under consideration. We think that the proposed experiments have the program headed in a better direction. The PRP had only a short time to discuss the detailed experimental proposals. The following are comments on the detailed proposals. We did not have time to discuss them as a group. They represent individual opinions and provided to you as feedback to your proposals.

  5. Fast models for fast particles transport in the context of ICF

    International Nuclear Information System (INIS)

    The energy transport in the Fast Ignition scheme within the framework of Inertial Confinement Fusion (ICF) is done by means of energetic charged particles, relativistic electrons or fast ions. The particle transport and energy deposition process is rather complicated and its detailed description requires large scale kinetic multidimensional calculations. These codes are CPU time consuming and cannot be easily implemented in radiation hydrodynamic codes that describe the fuel assembly, resulting energy deposition and the combustion. Reduced methods are needed that account for the main features of the kinetic transport process and are sufficiently fast and efficient to be introduced directly in an hydrodynamic module. We have developed two reduced models of charged particles transport, suitable for integration in hydro-codes. The first model, called Trumpet, is a two-dimensional extension of a simplified 1D model for the average scattering angle. The second model called M1 is a simplification of the Fokker Planck equation, based one the angular closure respecting the minimum entropy principle. These two models have been integrated in the CELIA hydrodynamic code (CHIC). After considering the advantages and limitations of these models, we used them to calculate the ion energy deposition in a compressed target. We have modelled the protonic radiography of a cylindrical laser-driven impulsion, and analyse a new fast ignition scheme with fast deuterium tritium and carbon ions accelerated by laser. (author)

  6. X-ray and EUV micro-imaging systems for laser ICF diagnostics

    International Nuclear Information System (INIS)

    Plasma imaging diagnostics plays an important role for laser ICF. Based on the urgent need to carry out high-resolution, high-throughput plasma diagnostics, grazing-incidence X-ray Kirkpatrick-Baez (KB) microscopes and normal-incidence EUV Schwarzschild imaging system were developed. The X-ray multilayer KB microscopes were successfully been applied in the physics experiments of SGII laser facility. Combined with streaked camera, the Mo-backlit implosion flow line of hollow Carbon-Hydrogen (CH) spherical target was obtained in SGII. The 4.75keV single-channel and four-channel KB microscopes were also developed for self-emission and short-pulse backlit imaging diagnostic of CH cylindrical target. In addition, according to the need of ultra-short laser pulse plasma diagnostics, the Schwarzschild imaging system working at 68eV was researched, and the physical experiments of hot electron transport with Schwarzschild imaging system were performed in SILEX-I laser facility

    We have developed preliminary conceptual laser system designs for the Laser ICF (Inertial Confinement Fusion) Fission Energy (LIFE) application. Our approach leverages experience in high-energy Nd:glass laser technology developed for the National Ignition Facility (NIF), along with high-energy-class diode-pumped solid-state laser (HEC-DPSSL) technology developed for the DOE's High Average Power Laser (HAPL) Program and embodied in LLNL's Mercury laser system. We present laser system designs suitable for both indirect-drive, hot spot ignition and indirect-drive, fast ignition targets. Main amplifiers for both systems use laser-diode-pumped Nd:glass slabs oriented at Brewster's angle, as in NIF, but the slabs are much thinner to allow for cooling by high-velocity helium gas as in the Mercury laser system. We also describe a plan to mass-produce pump-diode lasers to bring diode costs down to the order of $0.01 per Watt of peak output power, as needed to make the LIFE application economically attractive.

    The mixing between fuel and shell materials in Inertial Confinement Fusion (lCF) implosion cores is a current topic of interest. The goal of this work was to design direct-drive ICF experiments which have varying levels of mix, and subsequently to extract information on mixing directly from the experimental data using spectroscopic techniques. The experimental design was accomplished using hydrodynamic simulations in conjunction with Haan's saturation model, which was used to predict the mix levels of candidate experimental configurations. These theoretical predictions were then compared to the mixing information which was extracted from the experimental data, and it was found that Haan's mix model predicted trends in the width of the mix layer as a function of initial shell thickness. These results contribute to an assessment of the range of validity and predictive capability of the Haan saturation model, as well as increasing confidence in the methods used to extract mixing information from experimental data.

    In the 1990 National Academy of Sciences (NAS) report of its review of the U.S. Inertial Confinement Fusion (ICF) Program, it was recommended that a high priority be placed on completing the Precision Nova Project and its associated experimental campaign. Since fiscal year 1990, the lab has therefore campaigned vigorously on Nova and in its supporting laboratories to develop the Precision Nova capabilities needed to perform the stressful target experiments recommended in the 1990 NAS report. The activities to enable these experiments have been directed at improvements in three areas - the Nova laser, target fabrication capabilities, and target diagnostics. As summarized in the five articles in this report, the Precision Nova improvements have been successfully completed. These improvements have had a positive impact on target performance and on the ability to diagnose the results, as evidenced by the HEP-1 experimental results. The five articles generally concentrate on improvements to the capabilities rather than on the associated target physics experiments. Separate abstracts are included for each paper.

    Full Text Available In the present work, X-ray photoelectron spectroscopy (XPS is used to study sealed and unsealed anodic coatings obtained on pure-Al and on Al-Cu, Al-Mg-Si and Al-Mg alloys. In general, the sealing process is seen to produce a significant increase in the O/Al ratio in the anodic coatings. This increase is more considerable with the Al-Cu and Al-Mg alloys than with the pure Al and the Al-Mg-Si alloy, perhaps due to the greater porosity of the coatings obtained on the former. An attempt is made to establish possible relationships between anodic film characteristics and surface heterogeneities, which also act in the phase prior to anodising. According to the results of this work, these heterogeneities affect the degree of dissolution of the metallic substrate during the anodising operation.

    En el presente trabajo se estudian, mediante el análisis XPS (espectroscopia fotoelectrónica de rayos-X, los recubrimientos de anodizado, sellados y sin sellar, obtenidos sobre Al-puro y aleaciones de Al-Cu, Al-Mg-Si y Al-Mg. En general, se observa un aumento significativo en las relaciones O/Al en el recubrimiento como resultado del proceso de sellado. En el caso de las aleaciones de Al-Cu y Al-Mg, se ha observado también un significativo aumento de la relación O/Al respecto al Al-puro y la aleación Al-Mg-Si, que puede estar asociado a una mayor porosidad de los recubrimientos obtenidos sobre las primeras. Se ha intentado así mismo establecer posibles relaciones entre las características de las capas anódicas y las heterogeneidades superficiales que también han actuado en la fase previa al anodizado. Según los resultados de este trabajo, estas mismas heterogeneidades afectan el grado de disolución del substrato metálico durante la operación de anodizado.

Results obtained using a 0.1 M Na2SO4 solution revealed a greater anticorrosive protection of the four metallic materials as a result of the corrosion products formation. In addition, it was observed that when the outdoor exposure time increased the Ecorr values were more noble, those of Rp increased and the potentiodynamic anodic polarisation curves showed a greater slope of the linear regions and a shifting to the area of smaller current density in the E vs. log i diagrams. These results were not in a total agreement with those obtained by weight loss.

  17. Aurora: Los Alamos multikilojoule angular-multiplexed KrF driver prototype for ICF

    International Nuclear Information System (INIS)

    The Los Alamos National Laboratory (LANL) has participated in programs to apply high-power gas lasers to inertial confinement fusion (ICF). The bulk of this effort has been in the development of CO/sub 2/ laser systems and laser-plasma interaction experiments at a 10.6-μm wavelength. The main hardware element in this program is the Aurora KrF laser system, which is a prototype for using optical angular multiplexing and serial amplification by large electron-beam-driven KrF laser amplifiers to study KrF systems as potential fusion drivers. Aurora will serve as a test-bed for specific laser, optical, and electron-beam-pumping technology aspects of larger KrF fusion systems. The Aurora system is being built in two phases. The first-phase portion of the Aurora system contains all the main optical and laser elements from the front end to the final amplifier output. In the first phase, the front end output is replicated using aperture slicers and beam splitters to produce a 480-ns long pulse train consisting of 96 separate 5-ns pulses. This pulse train is encoded in angular separation, relayed through the amplifier chain by means of the centered optical system and the computer-controlled alignment station, and delivered to a diagnostic station which follows the main power amplifier [large aperture module (LAM)]. The second phase of the system contains the first-phase portion and the additional optical and target hardware needed to stack 48 of the 96 multiplexed and amplified beams into a single multikilojoule 5-ns pulse at the fusion target. The authors give a description of the Aurora system and discuss its present status

    Neutron scintillator diagnostics for ICF and HEDP can be characterized using the neutron time-of-flight (nTOF) line on Geneseo's 1.7 MV tandem Pelletron accelerator. Neutron signals can be differentiated from gamma signals by employing coincidence methods. A 1.8-MeV beam of deuterons incident on a deuterated polyethylene target produces neutrons via the 2H(d,n)3He reaction. Neutrons emerging at a lab angle of 88° have an energy of 2.96 MeV; the 3He ions associated with these neutrons are detected at a scattering angle of 43° using a surface barrier detector. The time of flight of the neutron can be measured by using the 3He detection as a ``start'' signal and the scintillation detection as a ``stop'' signal. This time of flight requirement is used to identify the 2.96-MeV neutron signals in the scintillator. To measure the light curve produced by these monoenergetic neutrons, two photomultiplier (PMT) tubes are attached to the scintillator. The full aperture PMT establishes the nTOF coincidence. The other PMT is fitted with a pinhole to collect single events. The time between the full aperture PMT signal and the arrival of the signal in the pinhole PMT is used to determine the light curve for the scintillator. This system will enable the neutron response of various scintillators to be compared.

    To date, most resources for ion beam fusion have been devoted to development of accelerators and target physics; relatively few resources have gone into ion beam transport development. Because of theoretical studies and substantial experience with electron beam transport, the ion beam transport community is now poised to develop and optimize ion beam transport for ICF. Because of this Tri-Lab effort, a path for coordinated development of ion beam transport has been established. The rate of progress along this path will now be determined largely by the availability of resources.

  2. Diagnostic techniques for measuring temperature transients and stress transients in the first wall of an ICF reactor

    International Nuclear Information System (INIS)

    The primary challenge in the design of an Inertial Confinement Fusion (ICF) power reactor is to make the first wall survive the frequent explosions of the pellets. Westinghouse has proposed a dry wall design consisting of steel tubes coated with tantalum. This report describes the design of a test chamber and two diagnostic procedures for experimentally determining the reliability of the Westinghouse design. The test chamber simulates the x-ray and ion pulse irradiation of the wall due to a pellet explosion. The diagnostics consist of remote temperature sensing and surface deformation measurements. The chamber and diagnostics can also be used to test other first-wall designs

    International Nuclear Information System (INIS)

    The complementary techniques of ion microtomography (IMT) and particle-induced x-ray emission (PIXE) are used to provide micro-characterization of inertial confinement fusion (ICF) targets for density uniformity, sphericity, and trace element spatial distributions. ICF target quality control in the laser fusion program is important to ensure that the energy deposition from the lasers results in uniform compression and minimization of Taylor-Rayleigh instabilities. We obtain 1% density determinations using IMT with spatial resolution approaching two microns. Utilizing PIXE, we can map out dopant and impurity distributions with elemental detection sensitivities on the order of a few ppm. We present examples of IMT and PIXE analyses performed on several ICF targets

  7. Using the International Classification of Functioning, Disability and Health (ICF to describe children referred to special care or paediatric dental services.

    Denise Faulks

    Full Text Available Children in dentistry are traditionally described in terms of medical diagnosis and prevalence of oral disease. This approach gives little information regarding a child's capacity to maintain oral health or regarding the social determinants of oral health. The biopsychosocial approach, embodied in the International Classification of Functioning, Disability and Health - Child and Youth version (ICF-CY (WHO, provides a wider picture of a child's real-life experience, but practical tools for the application of this model are lacking. This article describes the preliminary empirical study necessary for development of such a tool - an ICF-CY Core Set for Oral Health. An ICF-CY questionnaire was used to identify the medical, functional, social and environmental context of 218 children and adolescents referred to special care or paediatric dental services in France, Sweden, Argentina and Ireland (mean age 8 years ± 3.6 yrs. International Classification of Disease (ICD-10 diagnoses included disorders of the nervous system (26.1%, Down syndrome (22.0%, mental retardation (17.0%, autistic disorders (16.1%, and dental anxiety alone (11.0%. The most frequently impaired items in the ICF Body functions domain were 'Intellectual functions', 'High-level cognitive functions', and 'Attention functions'. In the Activities and Participation domain, participation restriction was frequently reported for 25 items including 'Handling stress', 'Caring for body parts', 'Looking after one's health' and 'Speaking'. In the Environment domain, facilitating items included 'Support of friends', 'Attitude of friends' and 'Support of immediate family'. One item was reported as an environmental barrier - 'Societal attitudes'. The ICF-CY can be used to highlight common profiles of functioning, activities, participation and environment shared by children in relation to oral health, despite widely differing medical, social and geographical contexts. The results of this empirical

    Here, we report a new and rapid radiosynthesis of {sup 18}F-N-[2-(diethylamino)ethyl]-6-fluoro-pyridine-3-carboxamide ([{sup 18}F]ICF01006), a molecule with a high specificity for melanotic tissue, and its evaluation in a murine model for early specific detection of pigmented primary and disseminated melanoma. [{sup 18}F]ICF01006 was synthesized using a new one-step bromine-for-fluorine nucleophilic heteroaromatic substitution. Melanoma models were induced by subcutaneous (primary tumour) or intravenous (lung colonies) injection of B16BL6 melanoma cells in C57BL/6J mice. The relevance and sensitivity of positron emission tomography (PET) imaging using [{sup 18}F]ICF01006 were evaluated at different stages of tumoural growth and compared to {sup 18}F-fluorodeoxyglucose ([{sup 18}F]FDG). The fully automated radiosynthesis of [{sup 18}F]ICF01006 led to a radiochemical yield of 61 % and a radiochemical purity >99 % (specific activity 70-80 GBq/{mu}mol; total synthesis time 42 min). Tumours were visualized before they were palpable as early as 1 h post-injection with [{sup 18}F]ICF01006 tumoural uptake of 1.64 {+-} 0.57, 3.40 {+-} 1.47 and 11.44 {+-} 2.67 percentage of injected dose per gram of tissue (%ID/g) at days 3, 5 and 14, respectively. [{sup 18}F]ICF01006 PET imaging also allowed detection of melanoma pulmonary colonies from day 9 after tumour cell inoculation, with a lung radiotracer accumulation correlated with melanoma invasion. At day 21, radioactivity uptake in lungs reached a value of 5.23 {+-} 2.08 %ID/g (versus 0.41 {+-} 0.90 %ID/g in control mice). In the two models, comparison with [{sup 18}F]FDG showed that both radiotracers were able to detect melanoma lesions, but [{sup 18}F]ICF01006 was superior in terms of contrast and specificity. Our promising results provide further preclinical data, reinforcing the excellent potential of [{sup 18}F]ICF01006 PET imaging for early specific diagnosis and follow-up of melanin-positive disseminated melanoma.

  13. Conceptual design of a large E-beam-pumped KrF laser for ICF commercial applications

    International Nuclear Information System (INIS)

    Two types of KrF lasers appear attractive as a driver for an ICF electric power plant. The original concept uses large electron-beam-pumped amplifiers and pure angular multiplexing to deliver short, shaped pulses to the target. A recently conceived alternate concept uses many small, long-pulse e-beam sustained discharge lasers which transfer their energy through the forward Raman process to a multiplexed set of beams to deliver the energy to target. Preliminary comparisons of the two systems indicate that the original concept has both a lower cost and a lower system efficiency, and both concepts appear to be nearly equally attractive as an ICF driver for an electric power plant. This paper examines a 4.8 MJ, 5 Hz KrF laser system designed using the original concept. The laser uses 24 main amplifiers arranged in eight sets of three amplifiers each. This layout optimizes both the optical system and the gas flow system, and uses a simple target illumination scheme that provides neutron shielding to allow hands-on maintenance in the laser hall

    The aim of this project was to use the International Classification of Functioning, Disability and Health (ICF) to develop an interdisciplinary instrument consisting of a Core Set, a number of codes selected from ICF, to describe the overall health condition of traumatised refugees. We intended to test 1) whether this tool could prove suitable for an overall description of the functional abilities of traumatised refugees before, during and after the intervention, and 2) whether the Core Set could be used to trace a significant change in the functional abilities of the traumatised refugees by comparing measurements before and after the intervention. In 2007, eight rehabilitation centres for traumatised refugees in Denmark agreed on a joint project to develop a tool for interdisciplinary documentation and monitoring, including physical, mental and social aspects of the person's health condition. ICF, developed and approved by WHO in 2001, was found suitable because it offers a common and standardised language and a corresponding frame of reference to describe health and associated conditions in terms of functioning rather than symptoms and diagnosis. Traumatised refugees are in most cases severely affected mentally by the traumas they have been subjected to, physically by injuries suffered during torture and war, psycho-somatically with pain, and socially by cultural uprooting, as well as by social difficulties in the exile community. The rehabilitation perspective thus seems to be more meaningful than the traditional treatment perspective because it takes into account the very complex situation of this group. The aim of the project was to find out whether any functional changes could be monitored using the instrument. The aim was neither to study nor to describe the effect of rehabilitation approaches, such as conditions related to traumatised refugees' networks or environments that might affect the refugees' living conditions. It was also not the intention to

    Membrane electrode assemblies (MEA) are the most important part of PEM fuel cells since their interface results in the electrochemical reactions that make the generation of electricity possible. The MEA is composed of a proton exchange membrane, both sides of which are impregnated with a catalyst layer, normally of carbon-supported platinum. Depending on the technique used for its fabrication (atomization, serigraphy, brush methods, chemical reduction, etc.), the properties of the MEA can be different in terms of porosity, distribution of the catalyst, thickness and structure of the catalyst layer, and the quality of the union between the catalyst layer and the membrane, etc. Currently, the porosity of the electrodes is generated by isopropanol evaporation (solvent used in the dye) during the fabrication process conducted in the Instituto de Investigaciones Electricas (IIE). This document presents the results obtained from adding a porous agent to the catalytic dye base composition used in the fabrication of MEA at the IIE. [Spanish] Los Ensambles Membrana-Electrodo (MEA's) son la parte mas importante en las celdas de combustibles tipo PEM, ya que en su interfaz se llevan a cabo las reacciones electroquimicas que hacen posible la generacion de electricidad.

Se estudia la variación del grado de cubrimiento de la superficie del electrodo en función del tiempo en la electroadsorción para procesos reversibles. El modelo básico considerado es el de Sirinivasan-Gileadi. Este ha sido ampliado por acoplamiento de un proceso de disolución química y por la participación de una resistencia óhmica. Recientemente se ha elaborado un modelo de formación de multicapas, aplicando las ecuaciones de Srinivasan-Gileadi a cada una de ellas, teniendo en cuenta la resistencia ohmica que cada capa opone al paso de corriente. Se analiza, además de la ley de cubrimiento superficial, el comportamiento de la relación corriente/potencial en los casos de monocapas y capas yuxtapuestas con o sin resistencia óhmica, mostrándose su influencia en el potencial del máximoThe objective of this work is to analyze and to compare different models for electrochemical formation of mono and yuxtaposed-layer. In particular, the variation of electrode surface coverage as a function of time is studied for electroadsorption in reversible reactions. The basic model is that of Srinivasan-Gileadi. This has been extended by coupling a chemical dissolution process and an ohmic resistance. A model for multilayers formation elaborated taking into account the Srinivasan-Gileadi model for each of them and considering the ohmic resistance that each layer opposes to the electrical current has also been analyzed. Besides the surface coverage law, the behavior of the current/potential relation in the cases of mono and yuxtaposed-layers with and without ohmic resistance are considered. The influence of these variables in the peak potential is shown

    Science.gov (United States)

    2013-01-01

    Background To understand the full burden of a health condition, we need the information on the disease and the information on how that disease impacts the functioning of an individual. The ongoing revision of the International Classification of Diseases (ICD) provides an opportunity to integrate functioning information through the International Classification of Functioning, Disability and Health (ICF). Discussion Part of the ICD revision process includes adding information from the ICF by way of “functioning properties” to capture the impact of the disease on functioning. The ICD content model was developed to provide the structure of information required for each ICD-11 disease entity and one component of this content model is functioning properties. The activities and participation domains from ICF are to be included as the value set for functioning properties in the ICD revision process. Summary The joint use of ICD and ICF could create an integrated health information system that would benefit the implementation of a standard language-based electronic health record to better capture and understand disease and functioning in healthcare.

    2012-12-01

    Full Text Available Abstract Background Medical work capacity evaluations play a key role in social security schemes because they usually form the basis for eligibility decisions regarding disability benefits. However, the evaluations are often poorly standardized and lack transparency as decisions on work capacity are based on a claimant’s disease rather than on his or her functional capacity. A comprehensive and consistent illustration of a claimant’s lived experience in relation to functioning, applying the International Classification of Functioning, Disability and Health (ICF and the ICF Core Sets (ICF-CS, potentially enhances transparency and standardization of work capacity evaluations. In our study we wanted to establish whether and how the relevant content of work capacity evaluations can be captured by ICF-CS, using disability claimants with chronic widespread pain (CWP and low back pain (LBP as examples. Methods Mixed methods study, involving a qualitative and quantitative content analysis of medical reports. The ICF was used for data coding. The coded categories were ranked according to the percentage of reports in which they were addressed. Relevance thresholds at 25% and 50% were applied. To determine the extent to which the categories above the thresholds are represented by applicable ICF-CS or combinations thereof, measures of the ICF-CS’ degree of coverage (i.e. content validity and efficiency (i.e. practicability were defined. Results Focusing on the 25% threshold and combining the Brief ICF-CS for CWP, LBP and depression for CWP reports, the coverage ratio reached 49% and the efficiency ratio 70%. Combining the Brief ICF-CS for LBP, CWP and obesity for LBP reports led to a coverage of 47% and an efficiency of 78%. Conclusions The relevant content of work capacity evaluations involving CWP and LBP can be represented by a combination of applicable ICF-CS. A suitable standard for documenting such evaluations could consist of the Brief ICF

  11. Normal histone modifications on the inactive X chromosome in ICF and Rett syndrome cells: implications for methyl-CpG binding proteins

    Directory of Open Access Journals (Sweden)

    Canfield Theresa K

    2004-09-01

    Full Text Available Abstract Background In mammals, there is evidence suggesting that methyl-CpG binding proteins may play a significant role in histone modification through their association with modification complexes that can deacetylate and/or methylate nucleosomes in the proximity of methylated DNA. We examined this idea for the X chromosome by studying histone modifications on the X chromosome in normal cells and in cells from patients with ICF syndrome (Immune deficiency, Centromeric region instability, and Facial anomalies syndrome. In normal cells the inactive X has characteristic silencing type histone modification patterns and the CpG islands of genes subject to X inactivation are hypermethylated. In ICF cells, however, genes subject to X inactivation are hypomethylated on the inactive X due to mutations in the DNA methyltransferase (DNMT3B genes. Therefore, if DNA methylation is upstream of histone modification, the histones on the inactive X in ICF cells should not be modified to a silent form. In addition, we determined whether a specific methyl-CpG binding protein, MeCP2, is necessary for the inactive X histone modification pattern by studying Rett syndrome cells which are deficient in MeCP2 function. Results We show here that the inactive X in ICF cells, which appears to be hypomethylated at all CpG islands, exhibits normal histone modification patterns. In addition, in Rett cells with no functional MeCP2 methyl-CpG binding protein, the inactive X also exhibits normal histone modification patterns. Conclusions These data suggest that DNA methylation and the associated methyl-DNA binding proteins may not play a critical role in determining histone modification patterns on the mammalian inactive X chromosome at the sites analyzed.

    International Nuclear Information System (INIS)

    This report compares two physics designs of the low energy end of an induction linac-ICF driver: one using electric quadrupole focusing of many parallel beams followed by transverse combining; the other using magnetic quadrupole focusing of fewer beams without beam combining. Because of larger head-to-tail velocity spread and a consequent rapid current amplification in a magnetic focusing channel, the overall accelerator size of the design using magnetic focusing is comparable to that using electric focusing

    Uncertainty Quantification (UQ) is a critical field within 21st century simulation science that resides at the very center of the web of emerging predictive capabilities. The science of UQ holds the promise of giving much greater meaning to the results of complex large-scale simulations, allowing for quantifying and bounding uncertainties. This powerful capability will yield new insights into scientific predictions (e.g. Climate) of great impact on both national and international arenas, allow informed decisions on the design of critical experiments (e.g. ICF capsule design, MFE, NE) in many scientific fields, and assign confidence bounds to scientifically predictable outcomes (e.g. nuclear weapons design). In this talk I will discuss a major new strategic initiative (SI) we have developed at Lawrence Livermore National Laboratory to advance the science of Uncertainty Quantification at LLNL focusing in particular on (a) the research and development of new algorithms and methodologies of UQ as applied to multi-physics multi-scale codes, (b) incorporation of these advancements into a global UQ Pipeline (i.e. a computational superstructure) that will simplify user access to sophisticated tools for UQ studies as well as act as a self-guided, self-adapting UQ engine for UQ studies on extreme computing platforms and (c) use laboratory applications as a test bed for new algorithms and methodologies. The initial SI focus has been on applications for the quantification of uncertainty associated with Climate prediction, but the validated UQ methodologies we have developed are now being fed back into Science Based Stockpile Stewardship (SSS) and ICF UQ efforts. To make advancements in several of these UQ grand challenges, I will focus in talk on the following three research areas in our Strategic Initiative: Error Estimation in multi-physics and multi-scale codes ; Tackling the "Curse of High Dimensionality"; and development of an advanced UQ Computational Pipeline to enable

    2014-09-01

    Full Text Available This article analyzes the implications of the acquisition of physical disability on everyday life situations of persons under occupational therapy care using the International Classification of Functioning, Disability and Health – ICF, with emphasis on contextual factors. The study included 11 adults and elderly with physical impairments resulting from neurological disorders who were under Occupational Therapy care at the Center for Teaching and Research at the University of Sao Paulo from 2009 to 2010. It’s an exploratory qualitative research conducted through documentary study and semi-structured interview for the administration of the ICF components. Changes in body functions are diverse, both mental and related to movement, and when coupled with contextual factors may result in different levels and types of disabilities, preventing participation in life situations. The analysis of contextual factors helps to identify and relate personal and environmental aspects and their dynamic interaction reflects processes that may cause disability, establishing the ICF as a valuable guide for research and development of rehabilitation practices that consider the different aspects of the reality of a person’s life.

  18. Progress in symmetric ICF capsule implosions and wire-array z-pinch source physics for double z-pinch driven hohlraums

    International Nuclear Information System (INIS)

    Over the last several years, rapid progress has been made evaluating the double-z-pinch indirect-drive, inertial confinement fusion (ICF) high-yield target concept (Hammer et al 1999 Phys. Plasmas 6 2129). We have demonstrated efficient coupling of radiation from two wire-array-driven primary hohlraums to a secondary hohlraum that is large enough to drive a high yield ICF capsule. The secondary hohlraum is irradiated from two sides by z-pinches to produce low odd-mode radiation asymmetry. This double-pinch source is driven from a single electrical power feed (Cuneo et al 2002 Phys. Rev. Lett. 88 215004) on the 20 MA Z accelerator. The double z-pinch has imploded ICF capsules with even-mode radiation symmetry of 3.1 ± 1.4% and to high capsule radial convergence ratios of 14-21 (Bennett et al 2002 Phys. Rev. Lett. 89 245002; Bennett et al 2003 Phys. Plasmas 10 3717; Vesey et al 2003 Phys. Plasmas 10 1854). Advances in wire-array physics at 20 MA are improving our understanding of z-pinch power scaling with increasing drive current. Techniques for shaping the z-pinch radiation pulse necessary for low adiabat capsule compression have also been demonstrated.

    2011-05-01

    Full Text Available Abstract Background The International Classification of Functioning, Disability and Health (ICF proposes three main constructs, impairment (I, activity limitation (A and participation restriction (P. The ICF model allows for all paths between the constructs to be explored, with significant paths likely to vary for different conditions. The relationships between I, A and P have been explored in some conditions but not previously in people with osteoarthritis prior to joint replacement. The aim of this paper is to examine these relationships using separate measures of each construct and structural equation modelling. Methods A geographical cohort of 413 patients with osteoarthritis about to undergo hip and knee joint replacement completed the Aberdeen measures of Impairment, Activity Limitation and Participation Restriction (Ab-IAP. Confirmatory factor analysis was used to test the three factor (I, A, P measurement model. Structural equation modelling was used to explore the I, A and P pathways in the ICF model. Results There was support from confirmatory factor analysis for the three factor I, A, P measurement model. The structural equation model had good fit [S-B Chi-square = 439.45, df = 149, CFI robust = 0.91, RMSEA robust = 0.07] and indicated significant pathways between I and A (standardised coefficient = 0.76 p Conclusion The significant pathways suggest that treatments and interventions aimed at reducing impairment, such as joint replacement, may only affect P indirectly, through A, however, longitudinal data would be needed to establish this.

  20. Sol-gel optical thin films for an advanced megajoule-class Nd:glass laser ICF-driver

    International Nuclear Information System (INIS)

    It is well established by manufacturers and users that optical coatings are generally prepared by the well known Physical Vapor Deposition (PVD) technology. In the authors' opinion sol-gel technology is an effective and competitive alternative. The aim of this paper is to emphasize on the sol-gel thin film work carried out at Centre d'Etudes de Limeil-Valenton (CEL-V) and concerning the technology for high power lasers. The authors will briefly discuss the chemistry of the sol-gel process, the production of optical coatings and the related deposition techniques. Finally, the paper describes the preparation and performance of sol-gel optical coatings they have developed to fulfill the requirements of a future 2 MJ/500 TW (351 nm) pulsed Nd:glass laser so-called LMJ (Laser MegaJoules). This powerful laser is to be used for their national Inertial Confinement Fusion (ICF) program, to demonstrate at the laboratory scale, ignition of deuterium-tritium fusion fuel. Moreover, the aim of this article is, hopefully, to provide a convincing argument that coatings and particularly optical coatings, are some of the useful products available from sol-gel technology, and that exciting developments in other areas are almost certain to emerge within the coming decade

    The discovery of the essential difference of maximum ion energy for TW-ps laser plasma interaction compared with the 100 ns laser pulses [1] led to the theory of a skin layer model [2] where the control of prepulses suppressed the usual relativistic self-focusing. The subsequent generation of two nonlinear force driven blocks has been demonstrated experimentally and in extensive numerical studies where one block moves against the laser light and the other block into the irradiated target. These blocks of nearly solid state density DT plasma correspond to ion beam current densities [3] exceeding 1010 A/cm2 where the ion velocity can be chosen up to highly relativistic values. Using the results of the expected ignition of DT fuel by light ion beams, a selfsustained fusion reaction front may be generated even into uncompressed solid DT fuel similar to the Nuckolls-Wood [4] scheme where 10 kJ laser pulses produce 100 MJ fusion energy. This new and simplified scheme of laser-ICF needs and optimisation of the involved parameters.

  2. A review of the ablative stabilization of the Rayleigh-Taylor instability in regimes relevant to ICF

    International Nuclear Information System (INIS)

    It has been recognized for many years that the most significant limitation of ICF is the Rayleigh-Taylor (R-T) instability. It limits the distance an ablatively driven shell can be moved to several times its initial thickness. Fortunately material flow through the unstable region at velocity vA reduces the growth rate to √1+kL/kg -βkvA with β from 2-3. In recent years experiments using both x-ray drive and smoothed laser drive to accelerate foils have confirmed our understanding of the R-T instability. The growth of small initial modulations on the foils is measured for growth factors up to 60 for direct drive and 80 for indirect drive. For x-ray drive large stabilization is evident After some growth, the instability enters the non-linear phase when mode coupling and saturation are also seen and compare well with modeling. Normalized growth rates for direct drive are measured to be higher, but strategies for reduction by raising the isentrope are being investigated. For direct drive, high spatial frequencies are imprinted from the laser beam and amplified by the R-T instability. Modeling shows an understanding of this ''laser imprinting.''

Method: The Brief ICF Core Set was slightly adapted to meet the needs of an interdisciplinary rehabilitation medicine team working in a university outpatient clinic and admitting patients referred from primary care. The Core Set categories were made measurable by means of eg, assessment instruments and clinical investigations. The resulting profile was given a workable shape to facilitate rapid understanding of the initial assessment outcome. Results: Individual patients showed different profiles of problems and resources, which facilitated individual rehabilitation planning. At the level of the study group, the profiles for the Core Set component Body Functions showed that most patients had severe impairment in the sensation of pain and exercise tolerance categories of function, but most had resources in the motivation and memory categories of function. Likewise, for the component Activities, most patients had limitations in lifting and carrying objects and remunerative employment, but most had resources in intimate relationships and family relationships. At first, the use of the modified Brief ICF Core Set in the team conference was rather time consuming, but after a couple of months of experience, the team assessment took

Métodos: foram analisadas 617 lesões não-palpáveis visualizadas ao ultra-som. Realizou-se a punção aspirativa por agulha fina (PAAF orientada pela ultra-sonografia, com análise citológica do material, diferenciando-as em cistos ou nódulos sólidos. Estes tiveram seu resultado citológico confrontado com o resultado histopatológico, nos casos em que foi realizada a biópsia cirúrgica. Resultados: das 617 lesões não-palpáveis, 471 eram cistos, sendo 451 cistos simples que apresentaram citologia negativa em todos os casos e 20 casos foram considerados cistos complexos. Destes, 3 (15% tiveram resultado citológico positivo ou suspeito e em 2 casos confirmou-se malignidade. Dos 105 nódulos sólidos, 63 apresentaram citologia negativa, sendo 59 concordantes com a biópsia e houve 4 casos (0,3% de resultado falso-negativo pela citologia. Todos, porém, apresentavam discordância entre imagem e citologia. Em 14 nódulos sólidos (13%, a citologia foi suspeita e, destes, 5 foram diagnosticados como carcinoma. Em outros 14 (13%, o material foi insatisfatório e 1 era carcinoma. Em 51 casos, o tríplice diagnóstico foi concordante e optou-se por seguimento clínico. Conclusão: a análise citológica do material dos cistos mamários simples é desnecessária, porém quando são complexos, a citologia é imperativa. Nas lesões sólidas não-palpáveis, é fundamental a correlação da citologia com o aspecto ultra-sonográfico e mamográfico; caso sejam discordantes, deve-se sempre prosseguir a investigação da lesão.Purpose: to determine the relationship between fine needle aspiration cytology guided by ultrasound of nonpalpable breast lesions

O objetivo deste estudo foi avaliar a utilidade da citologia combinada a citometria de fluxo para o diagnóstico de LNH, utilizando um painel de anticorpos monoclonais e estudo do ciclo celular. O material foi obtido através de aspiração de linfonodos por agulha fina de 78 pacientes. O painel de anticorpos monoclonais para análise em citometria de fluxo foi o seguinte: CD19/CD10, CD20/CD5, CD23, CD38/CD7, CD3/CD4, CD3/CD8, kappa/lambda. O diagnóstico final foi confirmado pela histologia convencional, considerada gold standard. Em 85% dos casos a citologia associada a imunofenotipagem e porcentagem de células em fase S permitiram um diagnóstico correto. Nos demais casos foi possível diferenciar linfomas B ou T e estimar grau de agressividade. O painel, embora pequeno, foi suficiente exceto para os anaplásicos e subclassificação dos linfomas T. Nestes casos, a morfologia foi mais importante que imunofenótipo, sendo este seguro apenas para linfomas linfoblásticos. A fração de fase S mostrou-se importante para diferenciar linfomas indolentes e de alto grau. Concluímos que esta técnica é uma boa alternativa para o diagnóstico de linfomas não-Hodgkin.

    Highlights: • Sinusoidal perturbed Al foil was prepared by single-point diamond turning. • Perturbed Al foil was measured by surface profiler and white light interferometer. • Perturbed Al foil and CH layer adhered with each other via a hot-press process. • Parameters and cross-section of the CH–Al perturbation target was characterized. - Abstract: A polystyrene (CH)/aluminum (Al) dual-layer perturbation target for hydrodynamic instability experiments in inertial confinement fusion (ICF) was designed and fabricated. The target was composed of a perturbed 40 μm Al foil and a CH layer. The detailed fabrication method consisted of four steps. The 40 μm Al foil was first prepared by roll and polish process; the perturbation patterns were then introduced on the surface of the Al foil by the single-point diamond turning (SPDT) technology; the CH layer was prepared via a simple method which called spin-coating process; finally, the CH layer was directly coated on the perturbation surface of Al foil by a hot-press process to avoid the use of a sticker and to eliminate the gaps between the CH layer and the Al foil. The parameters of the target, such as the perturbation wavelength (T) and perturbation amplitude (A), were characterized by a QC-5000 tool microscope, an alpha-step 500 surface profiler and a NT1100 white light interferometer. The results showed that T and A of the target were about 52 μm and 7.34 μm, respectively. Thickness of the Al foil (H1), thickness of the CH layer (H2), and cross-section of the dual-layer target were characterized by a QC-5000 tool microscope and a scanning electron microscope (SEM). H1 and H2 were about 40 μm and 15 μm, respectively, the cross-sectional photographs of the target showed that the CH layer and the Al foil adhered perfectly with each other.

  12. History of HERMES III diode to z-pinch breakthrough and beyond : learning about pulsed power and z-pinch ICF.

    2013-04-01

    HERMES III and Z are two flagship accelerators of Sandia's pulsed-power program developed to generate intense-ray fields for the study of nuclear radiation effects, and to explore high energy-density physics (including the production of intense x-ray fields for Inertia Confinement Fusion [ICF]), respectively. A diode at the exit of HERMES III converts its 20-MeV electron beam into-rays. In contrast, at the center of Z, a z-pinch is used to convert its 20-MA current into an intense burst of x-rays. Here the history of how the HERMES III diode emerged from theoretical considerations to actual hardware is discussed. Next, the reverse process of how the experimental discovery of wire-array stabilization in a z-pinch, led to a better theory of wirearray implosions and its application to one of the ICF concepts on Z--the DH (Dynamic Hohlraum) is reviewed. Lastly, the report concludes with how the unexpected axial radiation asymmetry measured in the DH is understood. The first discussion illustrates the evolution of physics from theory-to-observationto- refinement. The second two illustrate the reverse process of observationto- theory-to refinement. The histories are discussed through the vehicle of my research at Sandia, illustrating the unique environment Sandia provides for personal growth and development into a scientific leader.

    In this paper, the interaction of a self-focused laser beam with a DT fusion target in a plasma-loaded cone-guided ICF scheme has been presented. We propose here to merge a plasma-loaded cone with the precompressed DT target in order to strongly focus the incident laser beam on the core to improve the fusion gain. The WKB approximation is used to derive a differential equation that governs the evolution of beamwidth of the incident laser beam with the distance of propagation in the plasma medium. The effects of initial plasma and laser parameters, such as initial plasma electron temperature, initial radius of the laser beam, initial laser beam intensity and plasma density, on self-focusing and defocusing of the Gaussian laser beam have been studied. Numerical results indicate that with increasing the plasma frequency (or plasma density) in the cone, the laser beam will be self-focused noticeably, while for a thinner laser beam (with small radius), it will diverge as propagate in the cone. By evaluating the energy deposition of the relativistic electron ignitors in the fuel, the importance of electron transportation in the cone-attached shell was demonstrated. Moreover, by lessening the least energy needed for ignition, the electrons coupling with the pellet enhances. Therefore, it increases the fusion efficiency. In this scheme, with employing a plasma-loaded cone, the fusion process improves without needing an ultrahigh-intensity laser beam in a conventional ICF.

    Full Text Available The objective of the present study was to assess the effective thermal conductivity of the hair coat (k ef, mW.m-1.K-1 of Holstein cows in a tropical environment, as related to conduction and radiation in the absence of free convection. The average k ef was 49.72 mW.m-1.K-1, about twice the conductivity of the air (26 mW.m-1.K-1 and much less than that of the hair fibres (260 mW.m-1.K-1. The low k ef values were attributed mainly to the small cross area of individual hairs, ρef/ρf (17.2% and 21.3% for black and white hairs, respectively. White coats were denser, with longer hairs and significantly higher k ef (53.15 mW.m-1.K-1 than that of the black hairs (49.25 mW.m-1.K-1. The heritability coefficient of the effective thermal conductivity was calculated as h²=0.18 the possibility was discussed of selecting cattle for increased heat transfer through the hair coat.O objetivo neste trabalho foi estudar a condutividade térmica efetiva do pelame (k ef, mW.m-1.K-1 atribuída à condução e radiação na ausência de convecção livre no pelame de vacas Holandesas manejadas em ambiente tropical. A média para condutividade térmica efetiva do pelame foi 49,72 mW.m-1.K-1, quase o dobro da condutividade térmica do ar (26 mW.m-1.K-1 e bem inferior à do pelo (260 mW.m-1.K-1. O baixo valor observado para condutividade térmica efetiva do pelame deve-se principalmente à pequena área ocupada por pelos (ρef/ρf, que foi somente 17,2% e 21,3% nos pelames preto e branco, respectivamente. O pelame branco foi mais denso e formado por pelos mais compridos, logo sua condutividade térmica efetiva (53,15 mW.m-1.K-1 foi significativamente maior que a do pelame preto (49,25 mW.m-1.K-1. A herdabilidade para a condutividade térmica efetiva é de 0,18, o que indica a possibilidade de se fazer seleção para elevar a transferência de calor através da capa.

    Full Text Available It is important to know the thermal barrier deposition techniques since materials with low thermal conductivity in the barrier can be obtained from them. The dependence of the thermal conductivity with the temperature can be divided into four regions. In this work, we were interested in the study of used techniques for the manufacture of materials with a desirable low thermal conductivity that will be exposed to high temperatures that is to say, materials found in the III and IV region. In these regions the thermal conductivity can be reduced increasing the porosity of the material. Through the study of the thermal barrier deposition techniques we found that the thermal spray produces a coat with high porosity, being the low velocity flame spray technique the best to produce coat of La2Zr2O7 with a minimal thermal conductivity. The thermal spray technique is low cost and almost any material can be thermally sprayed, so this can be considered a very attractive technique for industrial applications. // RESUMEN Es importante conocer las técnicas de deposición de barreras térmicas ya que de ellas depende la obtención de materiales con baja conductividad térmica en la barrera. La dependencia de la conductividad térmica con la temperatura puede dividirse en cuatro regiones. En este trabajo estuvimos interesados en el estudio de las técnicas que se utilizan para la fabricación de materiales sometidos a muy altas temperaturas y donde se desea que su conductividad térmica sea baja, es decir, materiales que se encuentran en la región III y IV. En estas regiones se puede disminuir la conductividad térmica aumentando la porosidad del material. A través del estudio de las técnicas de deposición de barreras térmica, hemos encontrado que la técnica del spray térmico produce una alta porosidad en el recubrimiento, siendo el método de rociado con baja velocidad el mejor método para producir capas de La2Zr2O7 con mínima conductividad t

    The high energy density (HED) and inertial confinement fusion (ICF) physics community relies on increasingly sophisticated high power laser driven experiments to advance the field. We review early work in the design and analysis of such experiments, and discuss the problems encountered. By finding solutions to those problems we put the field on firmer ground, allowing the community to develop it to the exciting stage it is in today. Specific examples include: drive and preheat in complex hohlraum geometries with the complicating effects of sample motion; and issues in the successful design of laboratory soft x-ray lasers and in the invention of methods to reduce the required optical laser driver energy by several orders of magnitude.

    Full Text Available Abstract Background The upper extremity plays an important role in daily functioning of patients with Multiple Sclerosis (MS and strongly influences their quality of life. However, an explicit overview of arm-hand training programs is lacking. The present review aims to investigate the training components and the outcome of motor training programs for arm and hand in MS. Methods A computerized systematic literature search in 5 databases (PubMed, CINAHL, EMBASE, PEDro and Cochrane was performed using the following Mesh terms: Multiple Sclerosis, Rehabilitation, Physical Education and Training, Exercise, Patient-Centered Care, Upper Extremity, Activities of Daily Living, Motor Skills, Motor Activity, Intervention Studies and Clinical Trial. The methodological quality of the selected articles was scored with the Van Tulder Checklist. A descriptive analyses was performed using the PICO principle, including scoring of training components with the calculation of Hedges’g effect sizes. Results Eleven studies were eligible (mean Van Tulder-score = 10.82(SD2.96. Most studies reported a specific improvement in arm hand performance at the ICF level that was trained at. The mean number of training components was 5.5(SD2.8 and a significant correlation (r = 0.67; p  Conclusion Motor training programs (both at the ICF body function and activity level have shown to improve arm and hand performance in MS in which the value of the training specificity was emphasized. To optimize upper extremity training in MS the component ‘client-centred’ and ‘exercise progression’ may be important. Furthermore, given the importance attributed to the components ‘distribution based practice’, ‘feedback’ and ‘random practice’ in previous research in stroke patients, the use of these components in arm hand training should be explored in future research.

    Full Text Available A soldagem laser vem sendo utilizada como um importante processo de manufatura. Ela pode ser utilizada tanto no modo contínuo quanto no modo pulsado. No processo onde se utiliza laser pulsado é possível realizar soldas de costura em lâminas finas, através da sobreposição dos pulsos. Nesse caso a velocidade de soldagem é definida pela taxa de sobreposição, taxa de repetição e diâmetro do pulso. A soldagem de sobreposição de lâminas finas apresenta problemas típicos como distorção excessiva da junta soldada, falta de contato entre as lâminas a serem soldadas (presença de um gap de ar, perfuração da junta e presença de altos níveis de tensões residuais. O processo de laser pulsado é preferido em relação ao processo por laser contínuo, pois ele possibilita um melhor controle da energia de soldagem. O presente trabalho estudou a influência da energia do pulso, no caso processo de soldagem laser Nd:YAG, na soldagem de lâminas finas ( 100µm de aço inoxidável austenítico AISI 316L, utilizado no revestimento de sensores (que trabalham em ambiente corrosivo da indústria sucroalcooleira.

Foi feita secção entre a nona e a 11ª costelas da meia carcaça direita, de onde se separou músculo e capa de gordura, analisadas as concentrações de CLA e de ácidos graxos, por cromatografia gasosa. O fornecimento de óleo de soja resultou em maior concentração de CLA no músculo e na capa de gordura, e a adição de óleo de soja menores concentrações de ácidos graxos saturados, principalmente os ácidos mirístico e palmítico. Os animais que receberam a dieta com grão de soja integral também apresentaram menor teor de CLA e redução nas concentrações de mirístico e palmítico. Esses efeitos foram observados somente na capa de gordura e em menor intensidade.The effect of different fat sources on fatty acid concentrations in the muscle and in the fat layer of water buffalo steers was studied. Twelve water buffalo steers weighting 306±8kg, fed without additional fat, soybean grain or soybean oil and confined during 84 days were used. The animals were slaughtered after 16-hours-fasting and the carcass was cooled at 5ºC, for 24 hours. A section was extracted between 9th and 11th ribs from the right half carcass and this section was separated in bone, muscle and fat layer. In the last two fractions, the fatty acids, including conjugated linoleic acid (CLA, were quantified by gaseous chromatography. The soybean oil provided higher CLA concentrations in the steers muscle and fat layer. Moreover, the soybean oil inclusion promoted lower saturated fatty acids contents, mainly miristic and palmitic

Estos depósitos del Mioceno inferior son conocidos como "capas del Cabo Ladrillero" y "capas del Cabo San Pablo", siendo las "capas del Cabo Ladrillero superior" las analizadas en este trabajo. La zona de estudio, situada a una decena de kilómetros al norte del frente orogénico emergente (Punta Gruesa, permitió reconocer cuatro asociaciones de facies que registran depósitos gravitacionales resedimentados en un ambiente marino supra batial y una cuña deltaica progradante y somerizante hacia el noreste. Entre los rasgos más conspicuos observados en esta sucesión se destacan bancos deformados, intervalos macizos y abundantes diques clásticos, cuyo análisis estadístico indica un patrón transtensivo. Los microfósiles documentados en el área y utilizados previamente como herramienta para sostener un ambiente marino profundo provienen de niveles estratigráficos infrayacentes y corresponden a niveles de la Formación Desdémona y las capas del Cabo Ladrillero inferior, aflorantes hacia el sur de la zona de estudio. Las evidencias sedimentológicas no son concluyentes respecto de la batimetría, pero la ausencia de turbiditas clásicas, flujos hiperpícnicos, la abundancia de bancos deformados y resedimentados, restos vegetales y fragmentos de carbón son compatibles con un ambiente somero y deltaico con altas tasas de aporte y pendientes inestables antes que un ambiente marino profundo, y sugieren una historia compleja de la evolución del relleno sedimentario que no se explica meramente con los esquemas basados exclusivamente en el contenido de foraminíferos que domina en la literatura.In the cliffs of the Ladrillero cape, situated on the Atlantic coast of the Isla Grande de Tierra del Fuego, the uppermost records of the

    Full Text Available Abstract Background A wide range of outcomes have been assessed in trials of interventions for carpal tunnel syndrome (CTS, however there appears to be little consensus on what constitutes the most relevant outcomes. The purpose of this systematic review was to identify the outcomes assessed in randomized clinical trials of surgical interventions for CTS and to compare these to the concepts contained in the International Classification of Functioning, Disability and Health (ICF. Methods The bibliographic databases Medline, AMED and CINAHL were searched for randomized controlled trials of surgical treatment for CTS. The outcomes assessed in these trials were identified, classified and linked to the different domains of the ICF. Results Twenty-eight studies were retrieved which met the inclusion criteria. The most frequently assessed outcomes were self-reported symptom resolution, grip or pinch strength and return to work. The majority of outcome measures employed assessed impairment of body function and body structure and a small number of studies used measures of activity and participation. Conclusion The ICF provides a useful framework for identifying the concepts contained in outcome measures employed to date in trials of surgical intervention for CTS and may help in the selection of the most appropriate domains to be assessed, especially where studies are designed to capture the impact of the intervention at individual and societal level. Comparison of results from different studies and meta-analysis would be facilitated through the use of a core set of standardised outcome measures which cross all domains of the ICF. Further work on developing consensus on such a core set is needed.

En 1994, los mayores COP y COT se asociaron a manejos con períodos agrícolas previos cortos. En 2003, se encontraron diferencias entre SC en COT en la capa de 0-5 cm de profundidad, siendo PP, LC50 y SD50 los tratamientos con mayor COT. El COP fue más alto bajo PP, LC50 y SD50 a 0-5 y 0-20 cm de profundidad. A 0-5 cm COP bajo SD fue significativamente mayor que bajo LC. A 5-20 cm de profundidad, las diferencias en COP no fueron claras entre SC aunque, tendió a disminuir con los años bajo agricultura. La fertilización determinó mayor COP a 5-20 y 0-20 cm de profundidad. Las diferencias en la variación entre 1994 y 2003 entre SC fueron significativas para COP y COT. Por otro lado, la variación relativa de COP fue más alta que la de las otras variables. Se concluye que las rotaciones cortas de agricultura-pastura, la SD y la fertilización nitrogenada mejoran el COP y el COT.

    Soft X-ray mirror used in inertial confinement fusion (ICF) experiments have been preformed at the 4B7B beam-line of Beijing Synchrotron Radiation Facility (BSRF). The main factors influencing the mirror reflectance were investigated and confirmed to be the contamination and the installation angle of mirrors. Simulation of the reflectance of contamination mirrors confirms the contamination is the carbon and oxygen from oil in ICF experiments. The contamination can be effectively removed by a radio-frequency glow discharge treatment for mirrors. The reflectance of mirrors which is improved after cleaning process is found to be in good agreement with the calculation results.%在北京同步辐射装置上,通过对应用于惯性约束聚变(ICF)实验的平面镜反射率的进一步研究,提高了辐射温度的测量精度.进行了对软X射线平面镜反射率的测量、反射镜的清洗、反射率的模拟计算,证明影响反射率变化的主要因素是平面镜的安装角度和沾污.实验结果表明:平面镜的沾污主要来源于ICF实验中的油沾污,采用射频辉光放电清洗非常有效.

    The aim of this paper is to analyze the relation between components of disability with distinguished score of impairment, activity and participation questionnaire based on clinical data of persons with hand injuries. Impairment was evaluated by use of AMA guide 6th edition and disability by DASH questionnaire on Convenience sample of patients (N = 117), with chronic hand injuries. Linking and allocating items of the DASH were done based on the ICF Core Set for Hand Conditions and the opinions of a group of experts from different related fields. Data was analyses by using Kappa index, Chi square test and a set of Pearson, Part and Partial correlations coefficient. Most of the DASH items were allocated to the activity; one to four of the items could not be classified and 0 to 22 were classified as having overlap. Participation and activity scores correlated positively with each other (r > 0.80). Impairment had high correlation with activity and participation scores (>73). With controlling the effect of each or both construct, this relation between them with impairment diminished but still significant between activity and impairment. There is a huge overlap in definition of activity and participation. The most effecting item in relation of disability and impairment is activity restriction. Participation had no relation with impairment.

    We will present theoretical and computational results on Brillouin interactions between two beams in co-, counter-, and orthogonal propagation geometries. The beams will be structured (with speckle patterns), the plasma will have inhomogeneous flow including the Mach -1 surface. As the growth rate of the instability surpasses the natural frequency of the ion wave, the strong coupling regime (SCR) is reached, where reactive quasi-modes with intensity dependent frequency shifts result. This is especially true in laser hot spots. We trace the consequences of operations in this regime with different damping rates on the ion acoustic waves. We consider convective and absolute instabilities as well as the design of experiments which could examine these new regimes of instability behavior with new 10 psec time resolved diagnostics. Whether well enough conditioned beams can result after 10's or 100's of pairwise crossings in direct and indirect drive ICF configurations, and whether SRS can thus be strongly suppressed downstream, remains to be demonstrated. But the prospects exist for such new paths to instability control in a staged manner before STUD pulses are implemented.-

    Indirect drive ICF experiments were performed on the Omega laser at LLE, both with and without distributed polarization rotators (DPR) in the laser beams. The hohlraums were irradiated with a three-cone beam geometry, experimentally adjusted to produce high-yield implosions with no DPRs installed. X-ray images of the cores of these implosions showed a small but tolerable P2 asymmetry. Similar experiments with DPRs installed produced lower yields, and x-ray images of the imploded cores showed substantially increased P2 asymmetries, suggesting that the shallow-angle cone of beams, which transits through the longest length of plasma and along the shallowest density gradients, had substantially increased absorption compared to the no-DPR case. We will show high magnification (nearly 100x) x-ray images of the cores, along with fusion neutron data. For capsules driven with good symmetry, we show the neutron yield results from capsules whose surfaces have been deliberately roughened by a measured amount, in order to compare to mix models in simulations.

    Active participation and the highest level of independence during daily living are primary goals in neurorehabilitation. Therefore, standing and walking are key factors in many rehabilitation programs. Despite inconclusive evidence considering the best application and efficacy of robotic tools in the field of pediatric neurorehabilitation, robotic technologies have been implemented to complement conventional therapies in recent years. A group of experienced therapists and physicians joined in an "expert panel." They compared their clinical application protocols, discussed recurring open questions, and developed experience-based recommendations for robot-assisted treadmill therapy (exemplified by the Lokomat, Hocoma, Volketswil, Switzerland) with a focus on children with cerebral palsy. Specific indications and therapeutic goals were defined considering the severity of motor impairments and the International Classification of Functioning, Disability and Health framework (ICF). After five meetings, consensus was found and recommendations for the implementation of robot-assisted treadmill therapy including postsurgery rehabilitation were proposed. This article aims to provide a comprehensive overview on therapeutical applications in a fast developing field of medicine, where scientific evidence is still scarce. These recommendations can help physicians and therapists to plan the child's individual therapy protocol of robot-assisted treadmill therapy. PMID:26011438

    Kinetic effects on inertial confinement fusion have been investigated. In particular, inter-ion-species diffusion and suprathermal ion distribution have been analyzed. The former drives separation of the fuel constituents in the hot reacting core and governs mix at the shell/fuel interface. The latter underlie measurements obtained with nuclear diagnostics, including the fusion yield and inferred ion burn temperatures. Basic mechanisms behind and practical consequences from these effects are discussed.

    Laser-produced, micro-wire backlighters in a point-projection geometry, generating X-ray photons with energies ranging from 50keV to 200 keV, have been used to record time-resolved 2D radiographs of the dense cold fuel surrounding the hot spot of inertial confinement fusion implosions at the OMEGA facility [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)]. The radiographs have spatial and temporal resolution of ~10 μm and ~10 ps, respectively, and allow localized measurements of areal mass densities with 7% accuracy. The experimental results show 3D non-uniformities and lower than 1D expected areal densities attributed to drive asymmetries and hydroinstabilities. The areal density measurements from radiographs compare well to the values obtained from charged particle spectrometry. We are preparing similar experiments using this technique to obtain radiographs of cryogenic implosions at the National Ignition Facility.

    Full Text Available Since the beginning of time, the image has been present in our lives, taking up different functions. Throughout history, production and support techniques have changed and the image has gained more power to a point where, in some moments, it substitutes texts and drives opinion making. Therefore, the objective of this work is to analyze the visual elements found on the covers of Veja, Isto É and Época on the Isabela Nardoni’s case, verifying the significance of the image for the construction of narratives surrounding the facts. The theoretical and conceptual background used in the analysis is based on two authors: Harry Pross, who, through his signs relational theory, searches for the visual readings of several cultural texts by an axes interpretation (insideoutside, above-below, bright-dark. The other author, Ivan Bystrina, one of the main thinkers in Culture Semiotics, like Pross, understands the perception by axes, or poles, stressing that the negative always attracts more attention, emphasizing that these characteristics are based on archaic values still ingrained in man. In this work, it was possible to see, through the exposed references, significant elements for the visual construction of the narrative of a crime on magazine covers.Desde nossos primórdios, a imagem esteve presente assumindo diferentes funções no tempo.

  13. Comparison and physical interpretation of MCNP and TART neutron and γ Monte Carlo shielding calculations for a heavy-ion ICF system

    International Nuclear Information System (INIS)

    Inertial confinement fusion (ICF) aims to induce implosions of D-T pellets to obtain a extremely dense and hot plasma with lasers or heavy-ion beams. For heavy-ion fusion (HIF), recent research has focused on 'liquid-protected' designs that allow highly compact target chambers. In the design of a reactor such as HYLIFE-II [Fus. Techol. 25 (1984); HYLIFE-II Progress Report, UCID-21816, 4.82-100], the liquid used is a molten salt made of F10, Li6, Li7, Be9 (called flibe). Flibe allows the final-focus magnets to be closer to the target, which helps to reduce the focus spot size and in turn the size of the driver, with a large reduction of the cost of HIF electricity. Consequently the superconducting coils of the magnets closer to the D-T neutron source will potentially suffer higher damage though they can stand only a certain amount of energy deposited before quenching. This work has been primarily focusing on verifying that total energy deposited by fusion neutrons and induced γ rays remain under such limit values and the final purpose is the optimization of the shielding of the magnetic lens system from the points of view of the geometrical configuration and of the physical nature of the materials adopted. The system is analyzed in terms of six geometrical models going from simplified up to much more realistic representations of a system of 192 beam lines, each focused by six magnets. A 3-D transport calculation of the radiation penetrating through ducts, that takes into account the complexity of the system, requires Monte Carlo methods. The technical nature of the design problem and the methodology followed were presented in a previous paper [Nucl. Instr. and Meth. A 464 (2001) 410] by summarizing briefly the results for the deposited energy distribution on the six focal magnets of a beam line.

Esse processo de mistura entre gêneros musicais distintos, compreendido entre os músicos da época como "samba-jazz" ou "choro jazzístico", não se limitava em misturar elementos rítmicos harmônicos e melódicos, mas também negociar a presença de termos, imagens e vestimentas da cultura estadunidense no Rio de Janeiro pré Bossa Nova. É possível verificar nas capas de discos gravados por K-ximbinho que essa negociação entre duas culturas se manifestava em forma de imagens e textos e visavam informar ao consumidor a que cada obra se destinava, ressaltando a inovação do samba e choro e propondo a criação desse novo estilo musical.K-Ximbinho participated along with other musicians from the 1950s and 1960s in a process aimed at modernizing the samba and choro in the introduction of various jazz.elements into Brazilian traditional styles.

    Full Text Available The coat protein (CP gene of the potato virus Y strain "o" (PVY O was introduced into potato, cultivar Achat, via Agrobacterium tumefaciens-mediated transformation. Sixty three putative transgenic lines were challenged against the Brazilian strains PVY-OBR and PVY-NBR. An extremely resistant phenotype, against the two strains, was observed in one line, denominated 1P. No symptoms or positive ELISA results were observed in 16 challenged plants from this line. Another clone, named as 63P, showed a lower level of resistance. Southern blot analysis showed five copies of the CP gene in the extremely resistant line and at least three copies in the other resistant line. The stability of the integrated transgenes in the extreme resistant line was examined during several in vitro multiplications over a period of three years, with no modification in the Southern pattern was observed. The stability of the transgenes, the absence of primary infections and the relatively broad spectrum of resistance suggest that the extremely resistant line obtained in this work can be useful for agricultural purposes.O gene da capa protéica (CP do Potato virus Y estirpe "o", foi introduzido em batata cultivar Achat, via Agrobacterium tumefaciens.

    Full Text Available PURPOSE:To evaluate the preoperative assessment of thyroid nodules using ultrasound studies and cytology of nodular aspirates. SUBJECTS AND METHODS: 2,468 patients with thyroid nodules were examined from 1999 to 2005. All patients were clinically examined and underwent ultrasonography followed by fine-needle aspiration biopsy (FNAB and cytology. RESULTS:Nodules larger than 10 mm were classified ultrasonographically in a 4-tier system and received a score according to the criterion of possible malignancy. Cytological examinations were conducted independently by 2 cytologists and classified as benign (score 1, indeterminate (score 2, suspicious (score 3, and malignant (score 6. Combining both scores, an index was generated that would indicate a higher probability of malignancy (benign, doubtful, suspicious, and malignant. Thyroid surgery was performed in 274 patients. Of those, 115 patients had a score of 2 to 5 and only 8 had a histological diagnosis of thyroid cancer (6.9%. For patients with a score of 5 (n = 51, 11.5% had a malignant lesion, and 51% of the 61 patients with a score of 6 had confirmed thyroid cancer. Of the 98 patients with a combined score of 7 to 10, 99% had a histological confirmation of malignancy. CONCLUSIONS: The index score had a sensitivity of 94.1% and specificity of 77.5%. The overall accuracy was 85.8%. Therefore, we concluded that this methodology may improve the preoperative diagnosis of thyroid cancer in nodules larger than 10 mm. Association with other methods such as color Doppler echography, serum TSH concentration, galectin-3 expression analysis, and FDG/PET scan would be useful in avoiding the higher costs of thyroid surgical procedures.OBJETIVO: Avaliar a possibilidade de diagnóstico pré-operativo de nódulos da tireóide (de diâmetro superior a 10mm usando ultra-sonografia da glândula tireóide e citologia de punção aspirativa por agulha fina guiada pela ultra-sonografia.

    在惯性约束核聚变激光驱动装置中,光路庞大复杂且元器件众多,为保证激光系统正常运行需对光路进行精密调节.特别是装置中的多个4F系统,需调整激光光路使其聚焦后对准焦平面滤波小孔中心,以保证激光顺利通过并实现低通滤波作用.目前实际工程中采用凹透镜背光照明的方法判断光束是否准确过孔,但该方法步骤繁琐且调整精度较低,给实际光路调整带来了极大的不便.本文基于全息原理,提出了一种简单高效的4F系统光路调整方法,通过一特殊设计的分光照明衍射光学元件,可一步实现激光聚焦过孔的判断与调整,可有效解决现有4F系统光路调整的困难.%Numerous elements and huge laser system are existed in Inertial Confine Fusion driver (ICF).It is necessary to adjust light path accurately so as to ensure that the laser system can work normally.Expecially,the 4F system in ICF plays a role of low-pass filtering,so the purpose of adjusting is to make laser pass the center of filter hole in focus plane.Currently,the method in practical engineering is to use a concave lens for splitting light illumination to judge whether the beam pass the filter hole.However,the disadvantage of this method is tedious and low precision,which is inconvenient in actual adjusting.In this paper,a simple but effective way to adjust light path in 4F system is presented based on holography theory.With a specially designed diffractive optical element for splitting light illumination,judging and adjusting laser to pass the filter hole can be easily achieving.Thus,it can solve the difficulty of existing method.

    This thesis deals with the dynamics of accelerated ablative front spreading in Inertial Confinement Fusion experiments. ICF is designed for the implosion of a deuterium-tritium spherical target. The outer shell, the ablator, is irradiated providing a high level pressure inside the target. During this first stage, the ablation front propagating inwards is perturbed by hydrodynamics instabilities, which can prevent the fusion reaction in the decelerated stage. We propose here a study on Rayleigh-Taylor instabilities during ablation process, in the two dimensional case. In order to obtain a numerical solution, we perform an asymptotic analysis in the limit of a high temperature ratio, between the remaining cold ablator and the hot ablated plasma. This study is divided in two steps. First, the thermo-diffusive part of the set of equations is approximated by a Hele-Shaw model, which is then perturbed by the hydrodynamics part. Using a vortex method, we have to solve the advection of a vortical sheet moving with the ablation front. We compute the numerical solution on an Eulerian mesh coupled with a marker method. The thermal part is computed by implementing the Fat Boundary Method, recently developed. The hydrodynamic part is obtained from a Finite Volume scheme. (author)

    TotaIFina's successful bid for taking over Elf represents the victory of a certain type of 'discourse'. The strategist's ability to market his views resembles the marketer's ability to promote a product through packaging and advertising. Analyzing the publicity war between these two firms during the summer of 1999 sheds light on the strategist's ability to 'make strategy with words'. Out of the variety of explanatory factors and arguments for the success of such a takeover bid. 'managerial discourse' is not to be overlooked as a means for 'enacting' a strategy. (author)

    Full Text Available Coal, oil, natural gas, and shale gas are biomass that is formed millions of years ago. These are non-renewable and depleting, even considering the recent discovery of new sources of oil in the presalt and new technologies for the exploitation of shale deposits. Currently, these raw materials are used as a source of energy production and are also important for the production of fine chemicals. Since these materials are finite and their (oil price is increasing, it is clear that there will be a progressive increase in the chemical industry to use renewable raw materials as a source of energy, an inevitable necessity for humanity. The major challenge for the society in the twenty first century is to unite governments, universities, research centers, and corporations to jointly act in all areas of science with one goal of finding a solution to global problems, such as conversion of biomass into compounds for the fine chemical industry.Non-renewable raw materials are used in the preparation of fuels, chemical intermediates, and derivatives for the fine chemical industry. However, their stock in nature has a finite duration, and their price is high and will likely increase with their depletion. In this scenario, the alternative is to use renewable biomass as a replacement for petrochemicals in the production of fine chemicals. As the production of biomass-based carbohydrates is the most abundant in nature, it is judicious to develop technologies for the generation of chain products (fuels, chemical intermediates, and derivatives for the fine chemicals industry using this raw material. This paper presents some aspects and opportunities in the area of carbohydrate chemistry toward the generation of compounds for the fine chemical industry.

    2016-04-01

    Full Text Available In present flexible interconnections for transmission of required active power between different power systems is used, as a rule, so-called DC back-to-back link. The aim of this work is the investigation of proposed reactor-capacitor device for flexible connection of asynchronously alternating current power systems with the same nominal values of frequencies for parallel operation. The reactor-capacitor device was elaborated. The installation develops the idea of controlled reactor alternating current link, and provides reactive power balance in the unit and needed value of the output voltage module. The basic characteristics of reactor-capacitor device for controlled power transmission were investigated. Analytical expressions for device elements parameters were derived. These ensure necessary ratio of voltages modules of linked power systems and reactive power balance of the device at circular output voltage vector rotation for a given load admittance. Obtained parameters ensure constant active power flow between linked asynchronously power systems and device reactive power internal balance.

    Several samples of the solid solutions CeRu{sub 1-x}Pd{sub x}Sn and CeRh{sub 1-x}Pd{sub x}Sn have been synthesized by arc-melting and characterized by X-ray powder diffraction. Guinier powder patterns prove that the ZrNiAl-type structure is the dominating one, besides the CeRuSn and TiNiSi type structures. The structures of CeRu{sub 0.28}Pd{sub 0.72}Sn (ZrNiAl type, P anti 62m, a = 751.95(3), c = 418.70(2) pm, wR2 = 0.0274, 332 F{sup 2} values, 14 variables) and CeRh{sub 0.66}Pd{sub 0.34}Sn (ZrNiAl type, P anti 62m, a = 750.26(3), c = 411.59(2) pm, wR2 = 0.0533, 358 F{sup 2} values, 14 variables) were refined from single crystal diffractometer data. Magnetic measurements in combination with XANES (X-Ray Absorption Near Edge Structure) clearly proved intermediate cerium valencies for most compounds and revealed the best fitting parameters for those with the ICF model (Interconfiguration fluctuation). The electrical resistivity is also influenced by the substitutions. At low and high valence electron counts (VECs) metallic character is present, while around the VEC of CeRhSn the typical resistivity behavior for valence fluctuating compounds is observed.

    The United States continues to maintain its leadership in inertial confinement fusion as it moves toward the goal of ignition. The flagship of the program is the National Ignition Facility (NIF) presently under construction at Lawrence Livermore National Laboratory. Experiments had begun on the first four beams of the National Ignition Facility just at the time of the last IFSA Conference. Several new successful campaigns have been conducted since then in planar hydrodynamics and hohlraums as well as activating the VISAR diagnostic for equation of state experiments. Highlights of these results will be reviewed. Presently, the four beam experimental capability has been suspended while the first eight beams are being installed as the first step in building out the project. Meanwhile, much progress has been made in developing ignition designs for using NIF. An array of designs having several ablator materials have been shown computationally to ignite with energies ranging from the design energy to as low as 1 MJ of laser energy. Alternative direct drive designs in the NIF indirect drive configuration have been developed by LLE. This wide array of design choices has increased the chance of achieving ignition sooner on the facility. Plans are now being developed to begin an ignition experimental campaign on NIF in 2010, a little over a year after completion of the facility. Other US facilities are also implementing improved capabilities. Peta-watt lasers are now under construction at the University of Rochester and Sandia National Laboratory. The Z pulsed power machine at Sandia National Laboratory is being refurbished to improve its performance. The ongoing research program at the OMEGA laser at the University of Rochester and the Z machine at Sandia National Laboratory as well as at the Nike, Trident and Janus lasers remain strong, performing experiments supporting the NIF ignition plan and direct drive ignition. There also is an active program in the broader field of high energy density science on these facilities. These activities will be reviewed here as well as presented in talks throughout the conference. (authors)

  15. Laser-driven ICF experiments: Laboratory Report No. 223

    International Nuclear Information System (INIS)

    Laser irradiation uniformity is a key issue and is treated in some detail. The basic irradiation uniformity requirements and practical ways of achieving these requirements are both discussed, along with two beam-smoothing techniques: induced spatial incoherence (ISI), and smoothing by spectral dispersion (SSD). Experiments to measure and control the irradiation uniformity are also highlighted. Following the discussion of irradiation uniformity, a brief review of coronal physics is given, including the basic physical processes and their experimental signatures, together with a summary of pertinent diagnostics and results from experiments. Methods of determining ablation rates and thermal transport are also described. The hydrodynamics of laser-driven targets must be fully understood on the basis of experiments. Results from implosion experiments, including a brief description of the diagnostics, are presented. Future experiments aimed at determining ignition scaling and demonstrating hydrodynamically equivalent physics applicable to high-gain designs

  16. Advanced in the neutron feedback ICF reactor concept

    International Nuclear Information System (INIS)

    Results are reviewed and updated from an earlier design study of a novel nuclear-pumped flashlamp laser (NP-FL) inertial fusion energy (IFE) power reactor based on the neutron feedback concept for IFE. This concept includes nuclear pumping of the laser flashlamp, a D-T seeded D-3He target and magnetic protection of the first wall of the reactor chamber coupled with direct conversion of deflected charged particles. Advantages include an increased overall plant efficiency due to improved energy coupling via neutron feedback, increased thermal-to-electric energy conversion efficiency, and lower neutron activation and waste. These factors are reflected in a driver energy of 5 MJ and a target gain of only 50 for a 53 % efficient 1000-MWe power plant operating at 6 Hz, novel components involved. However, they require further technological development. Consequently, the NP-FL plant appears to provide a very attractive 'second-generation' IFE reactor. (authors)

  17. Cascade: a high-efficiency ICF power reactor

    International Nuclear Information System (INIS)

    Cascade attains a net power-plant efficiency of 49% and its cost is competitive with high-temperature gas-cooled reactor, pressurized-water reactor, and coal-fired power plants. The Cascade reactor and blanket are made of ceramic materials and activation is 6 times less than that of the MARS Tandem Mirror Reactor operating at comparable power. Hands-on maintenance of the heat exchangers is possible one day after shutdown. Essentially all tritium is recovered in the vacuum system, with the remainder recovered from the helium power conversion loop. Tritium leakage external to the vacuum system and power conversion loop is only 0.03 Ci/d

    2008-01-01

    A steady-state model for Brillouin and Raman backscatter along a laser ray path is presented. The daughter plasma waves are treated in the strong damping limit, and have amplitudes given by the (linear) kinetic response to the ponderomotive drive. Pump depletion, inverse-bremsstrahlung damping, bremsstrahlung emission, Thomson scattering off density fluctuations, and whole-beam focusing are included. The numerical code Deplete, which implements this model, is described. The model is compared with traditional linear gain calculations, as well as ``plane-wave'' simulations with the paraxial propagation code pF3D. Comparisons with Brillouin-scattering experiments at the Omega Laser Facility show that laser speckles greatly enhance the reflectivity over the Deplete results. An approximate upper bound on this enhancement is given by doubling the Deplete coupling coefficient. Analysis with Deplete of an ignition design for the National Ignition Facility (NIF), with a peak radiation temperature of 285 eV, shows enco...

    Low density small cell sized foams were developed to localize the liquid DT layer in a direct drive wetted foam laser fusion target. We have developed foams made from ultrahigh molecular weight polyethylene gels and polystyrene inverse emulsions. Materials in the density range of from 0.020 to 0.300 g/cc were prepared and characterized for cell size, mechanical properties, machinability, specific surface area, and wetting. Foams with a density of 0.05 g/cc were made with a cell size of less than 5 ..mu..m. A cell structure model was developed which relates the density and specific surface area to cell size and cell wall thickness. Wetting tests in organic solvents and in liquid hydrogen were used to characterize the capillary pressure, pore structure and uniformity of the foams. 13 refs., 9 figs., 2 tabs.

  20. Role of the NIF in the development of ICF applications

    International Nuclear Information System (INIS)

    The National Ignition Facility (NIF) is a 1.8 MJ (at 351 nm), 192 beam laser facility being built at the Lawrence Livermore National Laboratory (LLNL) to achieve inertial fusion ignition in the laboratory. The NIF Project is being designed and built by a team from LLNL, Los Alamos National Laboratory, Sandia National Laboratory, and the University of Rochester. When completed in 2003, it will be a multipurpose facility that will be used for many applications in national security, energy, and the basic sciences. In addition to the National Security Mission, these applications include, for example, electric power generation, space propulsion, and study of basic astrophysical phenomena in the laboratory. Such applications receive benefit both through the state- of-the-art technology developments necessary to build NIF and through specific experiments that will be performed on NIF

    At the recently completed National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, the initial set of diagnostics to be deployed are focused on measuring neutrons and γ's generated by d(t,n)α reactions in the imploded capsule. Although valuable for understanding pre-ignition experiments, this abbreviated diagnostic suite provides an incomplete picture of the plasma conditions obtained. Prompt radiochemical techniques, based on induced neutron and charged particle reactions within the imploded target, provide a novel and interesting new perspective. To enable these techniques requires the collection and assay of activated target material. In Nov. 2008, experiments were performed using the Omega Laser at the University of Rochester to study the efficiency of collecting debris from directly driven targets. Results from these experiments indicate that target debris was successfully collected, and the debris thermalization and transport scheme enhanced the debris collection up to 347% over direct collection.

    Point design ignition capsules designed for the National Ignition Facility (NIF) currently use an x-ray-driven Be(Cu) ablator to compress the DT fuel. Ignition specifications require that the mass of unablated Be(Cu), called residual mass, be known to within 1% of the initial ablator mass when the fuel reaches peak velocity. The specifications also require that the implosion bang time, a surrogate measurement for implosion velocity, be known to +/- 50 ps RMS. These specifications guard against several capsule failure modes associated with low implosion velocity or low residual mass. Experiments designed to measure and to tune experimentally the amount of residual mass are being developed as part of the National Ignition Campaign (NIC). Tuning adjustments of the residual mass and peak velocity can be achieved using capsule and laser parameters. We currently plan to measure the residual mass using streaked radiographic imaging of surrogate tuning capsules. Alternative techniques to measure residual mass using activated Cu debris collection and proton spectrometry have also been developed. These developing techniques, together with bang time measurements, will allow us to tune ignition capsules to meet NIC specs.

    Convective Raman or Brillouin amplification and competition between them in inhomogeneous, drifting plasmas are discussed. Based on a five-wave model, relations of the backscattering reflectivity between Raman and Brillouin are deduced, and the influence of inhomogeneity, drift, damping to the pattern of competition is analyzed. For the given plasma conditions and noise source, the backscatter spectrum can be constructed. Recent gas-filled hohlraum experiments at the SHEN-GUANG laser facility show good agreement between measured reflectivity and our model predictions. The features of side-scatter in overlapping laser beams are also studied. We observe that backward Raman scattering level of one pump beam can be significantly enhanced when the second beam crosses it. This can be explained as the induced stimulated Raman side scattering, and the scattering wave of the first beam is as the seed light of the second beam. The variance of Raman scattering level with the different crossing angles is investigated. An extended five-wave model including nonlinear damping and detuning of plasma wave is under consideration.

  7. Energy gain of ignitable targets in inertial confinement fusion (ICF

    Directory of Open Access Journals (Sweden)

    A. Parvazian,J Jafari

    2002-06-01

    Full Text Available   In order to determine the fusion energy gain in a target due to inertial confinement fusion, it is necessary to solve hydrodynamic equations governed on plasma behavior during confinement time. To compress spherical multilayer targets having fuel in the central part, they are irradiated by laser or heavy ion beams. A suitable mass ratio of a pusher is used to ignite the central part of the target. When compression is maximum, fuel density exceeds from 500 to 1000 times of the cold density. Temperature in the cold fuel region rises rapidly and cause the plasma and fusion reaction to take place. Calculations of density, temperature and pressure profiles in the plasma are necessary to obtain the energy flux of neurons, electrons and radiations coming out from the target. Using numerical solutions for continuity, the momentum and energy equations based on a defined continuity equation we prepared a computer program to calculate density, temperature and pressure profiles. The gain of the target as output to input energy is determined. Using this procedure to a designed target with deuterium-tritium (DT fuel derived by heavy ion beams gives an energy gain over 400.

  8. Fragmentation of suddenly heated liquids in ICF reactors. Revision 1

    International Nuclear Information System (INIS)

    Fragmentation of free liquids in Inertial Confinement Fusion reactors could determine the upper bound on reactor pulse rate because increased surface area will enhance the cooling and condensation of coolant ablated by the fusion x rays. Relaxation from the suddenly (neutron) heated state will move a liquid into the negative pressure region under the liquid-vapor P-V dome. The resulting expansion in a diverging geometry will hydrodynamically force the liquid to fragment, with vapor then forming from the new surfaces to fill the cavities. An energy minimization model is used to determine the fragment size that produces the least amount of non-fragment-center-of-mass energy; i.e., the sum of the surface and dilational kinetic energies. This model predicts fragmentation dependence on original system size and amount of isochoric heating as well as liquid density, Grueneisen parameter, surface tension, and sound speed. A two dimensional molecular dynamics code was developed to test the model at a microscopic scale for the Lennard-Jones fluid with its two adjustable constants chosen to represent lithium

    Opacities of FeIII - FeXV at Te =15-20 eV and densities 1.e16-1.e23 cm-3 have been computed with an improved version of the HULLAC code. More than 109 transitions have been computed, with different ways to account for configuration interactions (CI). Spectra with CI limited to each non-relativistic configuration (CIinNRC) are compared to more extended full Relativistic CI (RCI). The effect of increasing the size of the CI basis is investigated. These comparisons enable optimizing the method for each temperature/density regime. With powerful computers, HULLAC -generated opacity databases could then be envisioned, bypassing the need for statistical approximations.

LANL C2 technical highlights are: (1) Completed management self-assessment (MSA) of the upgraded 40-mm gun - we plan to fire the first preheated target mid-July. Diagnostics will include PDV; (2) Completed 5 Mie scattering experiments at Special Technologies Laboratory to measure the average particle diameter and particle size sensitivity to changes in geometry and surface finish; (3) Completed the 3rd experimental series at the Advanced Photon Source. Experiments focused in part on better synchronization of the gun system to the X-ray beam by proofing a new valve initiation system and by synchronizing the detectors to the RF signal provided by the beam; and (4) Obtained new Be data on twinning. The data indicates the shape of the flow curve is greatly altered by 'pre-twinning', and that twins disappear during strain path changes. It reflects the importance of 'microstructure aware' models for prediction of macroscopic response. LANL C3 DARHT status update - DARHT Camera team is working with MIT Lincoln Labs to understand recent problems with the Axis II camera and controllers. Camera 1 was returned to MIT for repair and found to have a wire detached from the image clock. Electrical bonding of the array was improved to eliminate potential grounding issues. Camera PR is at NNSA service center and is being tracked. LANL C4 technical highlights are: (1) Obtained first set of data from the new LANL Turbulent Mixing Tunnel (TMT). LANL is conducting very high resolution experiments to look at variable density mixing, and these efforts are centered around the TMT and the new vertical shock tube, both being commissioned this year. Designed to study variable-density turbulent flows where there are many modeling challenges Initial calibration experiment with air shown in figures. Characterization of the jet and calibration of the density and velocity diagnostics is in progress. (2) Target Fabrication: Installed and tested Te evaporation source for July opacity shots on Z-machine. Measurements from recently acquired evaporation source indicate a stable deposition rate upon equilibration. Two Al/Te codepositions were performed and analyzed demonstrating uniform deposition across the substrate. (3) Tested and delivered 11 capsules for the NIF DIME campaign. One capsule already integrated into a complete assembly with backlighters and alignment fiber at NIF. This is a challenge because the target assembly is 'free-standing'. Three more assemblies will be completed before the shot campaign in mid-July. (4) Delivered LANL parts for the Fanbolt/Pleiades NIF shots to GA and AWE. The assembly will occur in July. The shots are scheduled for mid-August. (5) Compared simulations of recent Omega Shock/Shear campaign with data. Preliminary simulations with turbulence model show good agreement with the extracted aluminum layer width from experiments as compared to a simulation with no mix. (6) Began characterization of mechanical behavior and fractography of materials for constitutive modeling.

    In 2011 a neutron imaging diagnostic was commissioned at the National Ignition Facility (NIF). This new system has been used to collect neutron images to measure the size and shape of the burning DT plasma and the surrounding fuel assembly. The imaging technique uses a pinhole neutron aperture placed between the neutron source and a neutron detector. The detection system measures the two-dimensional distribution of neutrons passing through the pinhole. This diagnostic collects two images at two times. The long flight path for this diagnostic, 28 m, results in a chromatic separation of the neutrons, allowing the independently timed images to measure the source distribution for two neutron energies. Typically one image measures the distribution of the 14 MeV neutrons, and the other image measures the distribution of the 6-12 MeV neutrons. The combination of these two images has provided data on the size and shape of the burning plasma within the compressed capsule, as well as a measure of the quantity and spatial distribution of the cold fuel surrounding this core. Images have been collected for the majority of the experiments performed as part of the ignition campaign. Results from this data have been used to estimate a burn-averaged fuel assembly as well as providing performance metrics to gauge progress towards ignition. This data set and our interpretation are presented.

Hemispherical capsule implosions have also been radiographed in Z in preparation for future experiments in fast ignition physics. Z-pinch-driven inertial fusion energy concepts are being developed. The refurbished Z machine (ZR) will begin providing scaling information on capsule and Z-pinch in 2006. The addition of a short pulse capability to ZBL will enable research into fast ignition physics in the combination of ZR and ZBL-petawatt. ZR could provide a test bed to study NIF-relevant double-shell ignition concepts using dynamic hohlraums and advanced symmetry control techniques in the double-pinch hohlraum backlit by ZBL.

    The Mexico city is classified as one of the more populated cities of the world which presents a decrease in the air quality and that gives place to a severe problematic in atmospheric pollution. To cooperate in the solution of this problem it is necessary to carry out studies that allow a better knowledge of the atmosphere of the city. This study presents the results of a monitoring campaign of fine particle carried out from September 21 to December 12, 2001 in three sites of the Mexico City center area. The samples were collected every third day with a collector type unit of heaped filters (Gent). The analysis of these samples was carried out in the 2 MV accelerator of the National Institute of Nuclear Research (ININ) applying the PIXE technique and with this analysis its were identified in the samples approximately 15 elements in each one of the 3 sites and was calculated the concentration in that its were present. With these results a database was created and by means of it mathematical treatment the Enrichment factor (FE), the time series of each element and the multiple correlation matrix were evaluated. The obtained results showed that the Civil Registration site (Salto del Agua) it was the more polluted coinciding that to a bigger concentration of activities a bigger increase in the pollution is generated.

    Full Text Available This paper offers a reflection about the writing of History, based on the study of Revista do Museu Paulista's covers, noticeably during the term of its two first directors, when a certain editorial continuity was preserved. Taken as "sources", namely as historian subjects, those covers reveal evidences of practices that allow one to reconstitute, in its historic dimensions, the complex connection between the creation of the Revista, its materiality, and the reading and interpretation efforts that condition and reflect liaisons with writers and readers during the first decades of the XXth Century, from São Paulo, where it was published..

    The complexation capacity of Cu and Pb and their labile and organic contents were determined separately for surface seawater samples from Yueqing Bay. The samples were prepared using Nuclepore filtration method yielding <1.0μm, <0.4μm and <0.2μm particulate water samples. Our data indicated that the <0.2μm colloidal fraction is a major carrier for distribution of copper in seawater. Affinity of Cu to marine microparticles plays an important role in the process. Pb however, tends to be absorbed by >0.2μm particles. The complexation capacity of Pb with <0.2μm particulates was smaller than that with 0.2-1.0μm particulates, and averaged 11.5 and 23.0nmol/L respectively. The results suggested that colloidal particles were responsible for the distribution and concentration of Pb in seawater.

    A model to forecast fire damp emission in thin, steep coal bed, mining in advance and backfill works, has been developed and validated. The model estimates the amount of methane released towards the works, including fire damp proceeding from the actually mined seam, as well as methane coming from adjacent seams layers, depending on easy-to find parameters. Methane coming from the mined seam is determined as a function of the methane concentration in the seam and methane from adjacent seams is assessed by the degassification degree. This parameter depends also on the distance to the mined seam. The influence volume of a thin, steep mined coal bed has been determined, in order to study which seams and layers release methane towards the works. The works to develop the methane emission model were done in a coal face on Maria seam, in San Antonio mine, belonging to HUNOSA. The validation works were carried out in 24 left south seam, in the belonging to Minas de Figaredo, S. A. (Author)

    Full Text Available Para este trabajo se seleccionó una especie de Amanita, parasitada probablemente por un Hyphomycete, que presenta un crecimiento anormal y sobre la cual no existen trabajos previos. Inicialmente se hicieron extracciones etanólicas del material fresco en frío y con soxhlet. Se realizó una marcha fotoquímica preliminar del extracto obtenido y se detectaron coumarinas, alcaloides, fenoles y glicósidos cardiotónicos. Posteriormente se estandarizó que la cromatografía de capa
    fina con el sistema hexano:acetona (7:3 permitió apreciar el mejor perfil cromatográfico. Con este sistema se inició una cromatografía de columna eluida a gradiente de la cual se obtuvieron 21 fracciones, que se agruparon en tres fracciones finales de acuerdo a su perfil cromatográfico. Para la cromatografía de capa fina de las fracciones se usó el sistema diclorometano:etanol (9,5:0,5 que presentó una buena separación. Finalmente se detectaron ocho compuestos mayoritarios caracterizados por su factor de retención y su patrón de coloración. Como aporte al conocimiento de esta especie sería recomendable un trabajo posterior para purificar estos compuestos y realizar su elucidación estructural. Actualmente, se desarrollan trabajos taxonómicos para determinar la especie de Amanita e identificar el agente parásito.

    Full Text Available Olive pulp lipoxygenase regiospecificity and hydroperoxide lyase substrate specificity are important parameters in order to justify the volatile composition of olive oil. A new radiolabelling method to determine simultaneously these properties using only thin layer chromatography steps is described in the present work. The method involves incubation of an enzyme preparation from olive pulp with radiolabelled linoleate, followed by the fractionation of the resulting lipid products, previously treated with 2,4-dinitrophenyl hydrazine, on thin layer chromatography plates coated with polyethylenglycol 400. The results obtained are in agreement with previous studies carried out by other methods.La regioespecificidad de la lipoxigenasa y la especificidad del sustrato hidroperóxido liasa de pulpa de aceituna son parámetros importantes en la justificación de la composición en volátiles del aceite de oliva. En este trabajo se describe un nuevo método de marcaje radioactivo para determinar simultáneamente estas propiedades, usando solo etapas de cromatografía en capa fina. El método implica la incubación de una preparación enzimática de pulpa de aceituna con linoleato marcado, seguido del fraccionamiento de los productos lipídicos resultantes, previamente tratados con 2,4-dinitrofenil hidrazina, sobre placas de cromatografía en capa fina soportadas con polietilenglicol 400. Los resultados obtenidos están de acuerdo con estudios previos llevados a cabo con otros métodos.

    1995-04-01

    Full Text Available The viscous and viscoelastic behaviour of food emulsions containing a mixture of egg yolk and sucrose stearate as a function of oil and sucrose stearate concentrations were studied. Oil concentrations ranged between 40- 55% w/w for emulsions containing 5% w/w sucrose stearate and sucrose ester concentrations varied between 0-10% w/w for emulsions containing 50% w/w oil. steady flow, linear oscillatory shear tests and droplet size distribution measurements were carried out. An increase in oil or emulsifier concentration produced an increase in both the steady-state viscosity and in the viscoelastic functions. The results have been explained on the basis of the relationship between the structural parameters and the rheology of the emulsions studied.

    Se ha estudiado la influencia que ejercen las concentraciones de aceite y emulsionante sobre el comportamiento viscoso y viscoelástico de emulsiones alimentarias con bajo contenido en aceite estabilizadas por una mezcla de yema de huevo y estearato de sacarosa. Se han preparado emulsiones variando la concentración de aceite entre el 40 y el 55% p/p en emulsiones con un 5% p/p en sucroéster y la concentración de sucroéster entre el 0 y el 10% p/p manteniendo un 50% p/p en aceite. Se han realizado medidas reológicas en cizalla oscilatoria dentro del intervalo de viscoelasticidad lineal, representativas de un estado imperturbado, y medidas en cizalla estacionaria, que causan una gran destrucción estructural. También se han determinado las distribuciones de tamaños de gota. Un aumento en el contenido de aceite o emulsionante produce un aumento de las funciones viscoelásticas dinámicas y de la viscosidad estacionaria. Estos resultados se explican en función de los parámetros estructurales de las emulsiones.

    Full Text Available Los aceros Dual Phase (DP han encontrado recientemente una fuerte aplicación en elementos estructurales en la industria automotriz, debido a la necesidad de disminuir peso. La soldadura de estos materiales cobra particular importancia considerando su aplicación estructural y los procesos relacionados en su fabricación. En particular la soldadura de resistencia por punto (RSW y semiautomática con alambre macizo y protección gaseosa (GMAW son ampliamente utilizados en la industria automotriz. El proceso de soldadura por plasma (PAW se caracteriza, entre los procesos de soldadura por arco, por ser el de mayor densidad de energía, presentando particular interés en aplicaciones de la industria automotriz (tailor welded blanks. El objetivo del presente trabajo fue estudiar la evolución microestructural y las propiedades de aceros DP soldados mediante los procesos RSW, GMAW y PAW. A este fin, se soldaron cuatro grados de aceros DP con resistencias mecánicas de 550, 700 y 850 MPa en espesores de 1 y 1,3 mm mediante los mencionados procesos. Se caracterizaron las microestructuras y se determinaron las propiedades mecánicas de las uniones soldadas para cada caso. Para los tres procesos se obtuvieron uniones soldadas de calidad satisfactoria. Se observó para todas las soldaduras, que en la ZAC se produce una disminución de la dureza por debajo del valor del material base, relacionada a la descomposición de la fase martensítica. Las soladuras por arco fueron las más afectadas.Dual Phase steels (DP have been used recently as an interesting option for structural elements, specialy in automotive industry, due to weight reduce requirements. Welding of these materials becomes particularly important considering their application as structural elements and the related manufacturing methods. In particular resistance spot welding (RSW and gas metal arc welding (GMAW are widely used in the automotive manufacturing. The plasma arc welding (PAW has the charateristic, within arc welding processes, to involve the highest energy density, being this parameter interesting to certain applications on automative industry (tailor welded blanks. The objective of this work is to study the microstructural evolution and properties of welded DP steels by mean of RSW, GMAW and PAW. In this regard four DP steels, with tensile strength of 550, 700 y 850 MPa and thickness of 1 and 1.3 mm, were welded by mean of mentioned welding processes. Microstructures were charaterized and mechanical properties for each weld joint were determined. For the three processes good quality welded joints were obtained. It was observed on heat affected zone (HAZ a softened zone whose hardness is below to initial base metal hardness. This softening is related to the dissolution of the martensitic phase due to thermal cycle introduced by welding. Arc welds were the most affected.

    Full Text Available In a purpose to confirm the efficiency of Fine needle aspiration cytology (FNAC for the diagnosis of lesions of the female dog mammary gland a study was conducted during a period of one year. 21 mastitis, 21 benign tumors and 17 malignant tumors were studied in 148 bitches, ranging from 3 to 17 years old. The histological examination was performed in most cases. The correlation between the results of the histological and the cytological examination was studied. The correlation between the results of the histological and the cytological examination was detected in 80% of all cases. The limitations of the FNAC are the false-positive cases. Since the diagnosis can not definitely diagnose, a surgical biopsy and histopathology should be done when there is a suspicion of clinically and not cytologically confirmed malignancy. In a clinical context, the method has much to offer by preventing bitches from suffering inappropriate surgeries and investigations and allowing surgeons to plan quickly and more rationally.

    In laser driven hohlraum capsule implosions on the National Ignition Facility, supra-thermal hot electrons generated by laser plasma instabilities can preheat the capsule. Time resolved hot electron Bremsstrahlung spectra combined with 30 keV x-ray imaging uncover for the first time the directionality of hot electrons onto a high-Z surrogate capsule located at the hohlraum center. In the most extreme case, we observed a collimated beaming of hot electrons onto the capsule poles, reaching 50x higher localized energy deposition than for isotropic electrons. A collective SRS model where all laser beams in a cone drive a common plasma wave provides a physical interpretation for the observed beaming. Imaging data are used to distinguish between this mechanism and 2ωp instability. The amount of hot electrons generated can be controlled by the laser pulse shape and hohlraum plasma conditions. This work performed under the auspices of the U.S. DOE by LLNL under Contract DE-AC52-07NA27344.

  1. Optical architecture for a multi-megajoule ICF driver incorporating megajoule class KrF amplifiers

    International Nuclear Information System (INIS)

    A gaseous amplifying medium should be scalable to any arbitrary size. A system architecture is reported which will produce 10 MJ with only four amplifiers in the last stage by making use of this scalability. The system described uses optical angular multiplexing for efficient utilization of such large KrF amplifiers. For such large amplifiers, each multiplex beamline carries 16 kJ toward the target chamber. This is because the pump duration need only be increased as the cube root of the output energy and is only 2050 ns. While the use of angular multiplexing does not increase the total count of beamlines, it does increase their length since space has to be provided for the temporal decoder; a possible site plan is shown. Optical beam tubes are filled with He to avoid propagation problems and to promote cleanliness. Single shot sacrificial windows are proposed for large amplifiers. Relatively large multiplexing angles reduce crosstalk to a manageable level

  2. Conceptual design of a hybrid KrF laser system for ICF commercial applications

    International Nuclear Information System (INIS)

    KrF lasers appear to be the most efficient lasers operating near the optimal wavelength for laser fusion. Most high-efficiency, low-cost KrF laser designs use large electron-beam driven amplifiers and use pure angular multiplexing for the required pulse compression. A recent study carried out by Los Alamos and Spectra Technology has defined a high-efficiency hybrid KrF laser system architecture that uses both angular multiplexing and Raman beam combination. The high overall system efficiency of this hybrid design, approximately 12%, is achieved primarily through the use of e-beam sustained discharge lasers (EBSDL), and by using the efficient forward rotational Raman process in hydrogen. The new system appears attractive as a commercial-applications driver because the calculated efficiency is higher than the usual large e-beam pumped (EBP) KrF laser/pure angular multiplexing approach. In this paper, the hybrid system architecture is described, and the tradeoffs with respect to the large EBP amplifier/angular multiplexed system are discussed

    2016-03-07

    An effort to develop sub-critical-density high-Z metal-doped and pure metal foams as laser-driven x-ray sources is described. The main idea is that the laser beams preferentially heat the electrons, and if the plasma is sufficiently low density so that the heating rate is greater than the equilibration rate via electron-ion collisions, then the electron temperature in the plasma is much greater than the ion temperature as long as the laser is on. In such a situation the plasma is not in local thermal equilibrium (LTE), it heats supersonically and volumetrically, and the conversion efficiency of laser beam energy to multi-keV L-shell and K-shell radiation is much higher than what it would be in LTE plasma.

These shots assessed breakout times and velocities of shocks at five different angles separated by 45°. Each target looked at three different locations on the capsule measuring the shock breakout time and speed. The experiments used a significantly larger hohlraum and energy in the laser pulse than in previous complex hydrodynamics hohlraums. LLNL conducted a shot on NIF to continue developing a high pressure drive platform for Rayleigh-Taylor strength experiments. VISAR was the primary diagnostic and returned good quality data.

  7. Core Temperature and Density Profiles from Multispectral Imaging of ICF Plasmas

    International Nuclear Information System (INIS)

    We have developed a multiple monochromatic x-ray imaging diagnostic using an array of pinholes coupled to a multilayer Bragg mirror, and we have used this diagnostic to obtain unique multispectral imaging data of inertial-confinement fusion implosion plasmas. Argon dopants in the fuel allow emission images to be obtained in the Ar He-b and Ly-b spectral regions, and these images provide data on core temperature and density profiles. We have analyzed these data to obtain quasi-three-dimensional maps of electron temperature and scaled electron density within the core for several cases of drive symmetry, and we observed a two-lobed structure evolving for increasingly prolate-asymmetric drive. This structure is invisible in broad-band x-ray images. Future work will concentrate on hydrodynamics simulations for comparison with the data

  9. Wire-array z-pinch: a powerful x-ray source for ICF

    International Nuclear Information System (INIS)

    The wire-array z-pinch has in a very short time achieved remarkable performance as a powerful (>200 TW), pulsed soft x-ray source of high efficiency (∼15%) and of great relevance to inertial confinement fusion. The underlying physics involves the transformation of wire cores to a plasma corona, the occurrence of uncorrelated axial instabilities, inward flowing low magnetic Reynolds number jets, sometimes an accumulated stable and dynamically confined precursor column, an almost constant velocity implosion when gaps occur in the wire cores and finally at stagnation a fast-rising soft x-ray pulse of typically 5 ns FWHM. Nested arrays improve the performance and can operate in several modes. Three hohlraum designs have been tested; one of these, the dynamic hohlraum, has achieved a radiation temperature of ∼230 eV and has compressed a capsule from 2 to ∼0.8 mm diameter with a neutron yield of > 1010 thermal DD neutrons. Lower mass stainless steel wire arrays are used for Kα radiation sources. Generally implosions lead to more energy radiated than the implosive kinetic energy, and this is hypothesized as being due to ion viscous heating, as fast-growing short wavelength nonlinear MHD instabilities are dissipated; record ion temperatures of 200-300 keV are predicted and have been measured for the stainless steel array on Z at Sandia

    The reentrant cone approach to Fast Ignition, an advanced Inertial Confinement Fusion scheme, remains one of the most attractive because of the potential to efficiently collect and guide the laser light into the cone tip and direct energetic electrons into the high density core of the fuel. However, in the presence of a preformed plasma, the laser energy is largely absorbed before it can reach the cone tip. Full scale fast ignition laser systems are envisioned to have prepulses ranging betwee...

  11. Progress on the physics of ignition for radiation driven inertial confinement fusion (ICF) targets

    International Nuclear Information System (INIS)

    Extensive modelling of proposed National Ignition Facility (NIF) ignition targets has resulted in a variety of targets using different materials in the fuel shell, using driving temperatures which range from 250 to 300 eV, and requiring energies which range from less than 1 MJ up to the full 1.8 MJ design capability of the NIF. Recent experiments on Nova have shown that hohlraum walls composed of a mixture of high Z materials could result in targets which require about 20% less energy. Nova experiments are being used to quantify the benefits of beam smoothing in reducing stimulated scattering processes and laser beam filamentation for proposed gas filled hohlraum targets on the NIF. Use of smoothing by spectral dispersion (SSD) with 2-3 A of bandwidth results in 15 W/cm2 for this type of hohlraum. The symmetry in Nova gas filled hohlraums is affected by the gas fill. A large body of evidence now exists which indicates that this effect is due to laser beam filamentation which can be largely controlled by beam smoothing. Here the first 3-D simulations of hydrodynamic instability for the NIF point design capsule are presented. These simulations, with the HYDRA radiation hydrodynamics code, indicate that spikes can penetrate up to 10 μm into the 30 μm radius hot spot before ignition is quenched. With capsules whose surface is modified by laser ablation, Nova experiments have been used to quantify the degradation of implosions subject to near NIF levels of hydrodynamic instability. (author)

  12. Ultra-dense deuterium: A possible nuclear fuel for inertial confinement fusion (ICF)

    International Nuclear Information System (INIS)

    The ejection of deuterons with kinetic energy release (KER) of 630 eV was proved recently by measuring the laser-induced ion time-of-flight (TOF-MS) with two different detectors at different distances [S. Badiei, P.U. Andersson, L. Holmlid, Int. J. Mass Spectrom. 282 (2009) 70]. Realizing that the only possible energy release mechanism is Coulomb explosions, the D-D distance in the ultra-dense deuterium was determined to be constant at 2.3 pm. Using a long TOF-MS path now gives improved resolution. We show the strong effect of collisions in the ultra-dense material, and demonstrate that the kinetic energy of the ions increases with laser pulse power but that the number of ions formed is independent of the laser pulse power. This indicates special properties of the material. We also show that the two forms of condensed deuterium D(1) and D(-1) can be observed simultaneously as well resolved mass spectra of different forms. No intermediate bond lengths are observed. The two forms of deuterium are stable and well separated in bond length. We suggest that they switch rapidly back and forth as predicted by theory. A loosely built form with planar clusters of D(1) is observed here to be related to D(-1) formation.

    In order to capture just how nonuniform and degraded the symmetry may become of an imploding inertial confinement fusion capsule one may resort to the analysis of high energy X ray point projection backlighting generated radiographs. Here we show new results for such images by using methods of modern harmonic analysis which involve different families of wavelets, curvelets and WaSP (wavelet square partition) functions from geometric measure theory. Three different methods of isolating morphologically diverse features are suggested together with statistical means of quantifying their content for the purposes of comparing the same implosion at different times, to simulations and to different implosion images.

    Full Text Available Aim of this paper is to describe functioning of subjects with “severe disability” collected with a protocol based on the International Classification of Functioning, Disability, and Health. It included sections on body functions and structures (BF and BS, activities and participation (A&P, and environmental factors (EF. In A&P, performance without personal support (WPS was added to standard capacity and performance. Persons with severe disability were those reporting a number of very severe/complete problems in BF or in A&P-capacity superior to mean + 1SD. Correlations between BF and A&P and differences between capacity, performance-WPS, and performance were assessed with Spearman's coefficient. Out of 1051, 200 subjects were considered as severely disabled. Mild to moderate correlations between BF and A&P were reported (between 0.148 and 0.394 when the full range of impairments/limitations was taken into account; between 0.198 and 0.285 when only the severe impairments/limitations were taken into account; performance-WPS was less similar to performance than to capacity. Our approach enabled identifying subjects with “severe disability” and separating the effect of personal support from that of devices, policies, and service provision.

  18. The potential for reducing the cost of a heavy ion accelerator for ICF: Final report

    International Nuclear Information System (INIS)

    This study was initiated to identify the high leverage areas for reducing the cost of a 10 MJ heavy ion beam driver for a high gain target development facility. Our efforts to innovate to reach affordable cost have been mostly successful, in that it looks like the $500 M range may indeed be possible. We conclude that heavy ion beams do have substantial promise for an inertial fusion driver. However, the pace of R and D would have to be substantially increased to realize this promise on a timescale necessary for a High Gain Test Facility

    Full Text Available The objective of this research is to provide a standardized platform to monitor and predict indicators of people with traumatic brain injury using the International Classification of Functioning, Disability and Health, and analyze its potential benefits for people with disabilities, health centers and administrations. We developed a platform that allows automatic standardization and automatic graphical representations of indicators of the status of individuals and populations. We used data from 730 people with acquired brain injury performing periodic comprehensive evaluations in the years 2006–2013. Health professionals noted that the use of color-coded graphical representation is useful for quickly diagnose failures, limitations or restrictions in rehabilitation. The prognosis system achieves 41% of accuracy and sensitivity in the prediction of emotional functions, and 48% of accuracy and sensitivity in the prediction of executive functions. This monitoring and prognosis system has the potential to: (1 save costs and time, (2 provide more information to make decisions, (3 promote interoperability, (4 facilitate joint decision-making, and (5 improve policies of socioeconomic evaluation of the burden of disease. Professionals found the monitoring system useful because it generates a more comprehensive understanding of health oriented to the profile of the patients, instead of their diseases and injuries.
