    The present work describes the pattern of the denominated installation Phebus developed and used by the National Commission of Nuclear Security and Safeguards for their participation in the International Standard Problem ISP-46, organized by the Nuclear Energy Agency (NEA). The exercise consisted on the simulation of the denominated experiment Phebus FPT1 carried out in the experimental installation Phebus located in the Institut de Protection et de Surete Nucleaire of France. The experiment Phebus FP1 had as objective to evaluate the capacity of different computer codes to model in integral form the physical processes that are carried out during a severe accident in a pressurized water reactor (PWR), from the degradation of the core until the late stage with the formation of a pool of fused material, hydrogen production, liberation and transport of fission products, phenomena in the contention and chemistry of the iodine. The CNSNS uses the version bi of the SCDAPSIM code developed by the company Innovative Software Systems to simulate the International Standard Problem 46. The obtained results showed that the code is able to predict the thermohydraulic part of the experiment, however the same thing doesn't happen to the parameters related with the one fused of the fuel.

    This report summarises the CIEMAT contribution to the analysis of the FPT1 test of the PHEBUS-FP Project. The work carried out has been focussed on containment phenomena. the thermal hydraulic evolution and the aerosol behaviour has been simulated with CONTAIN 2.0 code, whereas the iodine chemistry has been modelled with IODE 4.2. In both cases a number of hypotheses and approximations have been adopted. The FPT1 experiment investigated core degradation and release, transport and behaviour of fission products and aerosols under the anticipated conditions for a low pressure accident sequence with a pipe break at the cold leg. The containment scenario was essentially characterised by a condensing and unsaturated atmosphere in contact with an acidic sump. CONTAIN 2.0 has provided an accurate picture of the thermo-hydraulic and aerosol behaviour, whereas IODE 4.2, although succeeded in predicting the overall iodine mass distribution, but it has been unable to capture the gaseous iodine evolution during the experiment. Steam input and condensation determined the thermal conditions of the vessel and made around 30% of particulate mass deplete onto condensing structures. Most of iodine was trapped by silver from the control rods and formed AgI in the sump. the deviations of predictions regarding gaseous iodine point out the need of further development of organics-iodine interaction models. Finally, it should be underlined that the simulation has shed light on experimental aspects as well. The measured steam input history should have been slightly different from the one specified in the final report: a new profile has been proposed. The samplings of airborne caesium (rather different from the {gamma}-spectrometry data) are the most reliable measurements. (Author) 10 refs.

    Thermal-hydraulic and aerosol phenomena which occurred in the containment vessel of the Phebus integral experimental facility during the first 30000 s of the Phebus FPT1 test were simulated with the CONTAIN thermal-hydraulic computer code. A single-cell input model of the vessel was developed, and boundary and initial conditions that were determined during the experiment were applied. The comparison of experimental and calculated results shows that, although the atmosphere temperature was well simulated, the calculated condensation rate was apparently too high, resulting in a lower pressure of the containment atmosphere. The aerosol deposition process was well simulated.(author)

    Noise analysis has been performed for measurement data obtained during PHEBUS-FPT1 test. The purpose of the study is to evaluate the applicability of the noise analysis to the following problems: To get more knowledge about the physical processes going on during severe core conditions; To better understand the core melting process; To establish appropriate on-line shut-down data. Results of the study indicate that the noise analysis is quite promising as a tool for investigating physical processes during the experiment. Compared with conventional approach of evaluating the signal's mean value behaviour, the noise analysis can provide additional, more detailed information: It was found that the neutron flux signal is subjected to additional reactivity perturbations in conjunction with fuel melting and relocation. This can easily be detected by applying noise analysis for the neutron flux signal. It has been demonstrated that the method developed in the present study can provide more accurate estimates of the onset of fuel relocation than using temperature signals from thermocouples in the thermal shroud. Moreover, the result suggests a potential of the present method for tracking the whole process of relocation. The result of the data analysis suggests a possibility of sensor diagnostics which may be important for confirming the quality and reliability of the recorded data. Based on the results achieved it is believed that the combined use of noise analysis and thermocouple signals will provide reliable shut-down criteria for the experiment. 8 refs

  6. Simple probabilistic approach to evaluate radioiodine behavior at severe accidents: application to Phebus test FPT1

    2007-01-01

    The contribution of radioiodine to risk from a severe accident is recognized to be one of the highest among all the fission products. In a long term (e.g. several days), volatile species of iodine are the most important forms of iodine from the safety point of view. These volatile forms ('volatile iodine') are mainly molecular iodine, I 2 , and various types of organic iodides, RI. A certain controversy exist today among the international research community about the relative importance of the processes leading to volatile iodine formation in containment under severe accident conditions. The amount of knowledge, coming from experiments, of the phenomenology of iodine behavior is enormous and it is embedded in specialized mechanistic or empirical codes. An exhaustive description of the processes governing the iodine behavior in containment is given in reference 1. Yet, all this knowledge is still not enough to resolve some important questions. Moreover, the results of different codes -when applied to relatively simple experiments, such as RTF or CAIMAN - vary widely. Thus, as a complement (or maybe even as an alternative in some instances) to deterministic analyses of iodine behavior, simple probabilistic approach is proposed in this work which could help to see the whole problem in a different perspective. The final goal of using this approach should be the characterization of uncertainties of the description of various processes in question. This would allow for identification of the processes which contribute most significantly to the overall uncertainty of the predictions of iodine volatility in containment. In this work we made a dedicated, small event tree to describe iodine behavior at an accident and we used that tree for a simple sensitivity study. For the evaluation of the tree, the US NRC code EVNTRE was used. To test the proposed probabilistic approach we analyzed results of the integral PHEBUS FPT1 experiment which comprises most of the important

    An on-line aerosol monitor (OLAM2) has been developed and tested for PHEBUS test FPT1. OLAM2 utilizes new detachable fiber optic cables and sapphire light pipes for light transmission between the OLAM and the electronics. This light transmission system was tested and found to provide better signal-to-noise performance than was achieved with the continuous fibers used for test FPT0. An additional advantage of the detachable fiber/light pipe system is ease of installation. Aerosol testing (OLAM calibration) was performed in order to verify adequate signal-to-noise performance of the new fiber optic system over the specified operating conditions and to check the quantitative light attenuation measurements against theoretical predictions. Results of the testing indicated that light extinction measurements obtained during Phebus tests could be used to estimate aerosol volume concentrations, if diamond window fouling can be avoided. OLAM2 was also subjected to a proof pressure test and a long-term thermal stability test. These tests verified the mechanical and thermal integrity of the OLAM within design specifications. Long-term output signal stability was also verified with the system maintained at design temperature and half-design pressure

    The present work describes the pattern of the called Quench installation developed and used by the National Commission of Nuclear Security and Safeguards (CNSNS) for their participation in the International Standard Problem 45 (ISP), organized by the Nuclear Energy Agency (NEA). The exercise consisted on the simulation of the denominated experiment Quench-06 carried out in the experimental installation Quench located in the Forschungszentrum laboratory in Karlsruhe, Germany. The experiment Quench-06 consisted on simulating the sudden and late injection of water in a fuel assemble for a pressurized reactor (PWR). The CNSNS uses the version bd of the SCDAPSIM code developed by the company Innovative Software Systems (ISS) to simulate this experiment. The obtained results showed that the code is able to predict the experiment partially when overestimating the hydrogen production and of the partial fused of some fuel pellets, but predicting correctly the damage in the shroud.

    In order to facilitate and to simplify the development and analysis of a Hybrid System in reference to its design, construction, operation and maintenance, it turns out optimal to carry out the simulation of this one by means of software, with which a significant reduction in the investment costs is obtained. Given the mix of technology of electrical generation which is involved in a hybrid system, it is very important to have a tool integrated with specialized packages of calculation (software), that allow to carry out the simulation tasks of the operational functioning of these systems. Combined with the former, one must not fail to consider the operation characteristics, the facilities of the user, the clarity in the obtained results and the possibility of its validation with respect to prototypes orchestrated in field. Equally, it is necessary to consider the identification of tasks involved in relation to the place of installation of this electrification technology. At the moment, the hybrid systems technology still is in a stage of development in the international level, and exist important limitations as far as the methodology availability and engineering tools for the optimum design of these systems. With the development of this paper, it is intended to contribute to the advance of the technology and to count on own tools to solve the described series of problems. In this article are described the activities that more impact have in the design and development of hybrid systems, as well as the identification of variables, basic characteristics and form of validation of tools in the integration of a methodology for the simulation of these systems, facilitating their design and development.

    2008-09-15

    Currently, most turbogenerator control systems consist of decentralized control schemes with independent control-loops for the turbine and the generator. These schemes do not take into account the interaction between the power and voltage control loops, which can degrade the turbogenerator response. To improve this situation, and to develop better control schemes, it is necessary to build full-scope mathematical models of the turbine generator set, which are able to emulate the dynamics throughout the operating range, including the interaction effects. In this thesis the mathematical model of a synchronous generator, which includes damping windings and rotor iron magnetic saturation, is developed. The model was modularly programmed using per-unit parameters. This model was coupled to the existing model of a gas turbine to compose the full-scope model of a 32 MVA combustion turbogenerator. The numerical stability of the generator and turbogenerator models demonstrated through steady-state simulation experiments. The dynamic behavior was demonstrated using power and voltage control loops based on digital PID algorithms. Then, the results of previous experiments were used to design a control scheme based on two fuzzy compensators: one for power and another for voltage. The proposed fuzzy scheme significantly reduced the unwanted interaction effects of decentralized conventional control schemes. It was demonstrated the proposed turbogenerator model is valid in a wide operating range and allows designing and evaluating high performance control schemes, which take into account the interaction between the turbine and the generator. Besides, the turbogenerator model is being used at the Electrical Research Institute to integrate a real-time bench test for turbogenerator control systems.

    Full Text Available La región varón específica del cromosoma Y, es extensamente estudiada a nivel de la evolución humana, siendo una oportunidad única para analizar los efectos de factores evolutivos en la dinámica de los haplotipos basados en microsatélites por carecer de recombinación. En diferentes poblaciones, distribuidas a nivel mundial, se encuentran “pseudoequilibrios” de ligamiento entre microsatélites del cromosoma Y. Por lo cual, la prueba de desequilibrios de ligamiento (LD, puede ser una herramienta para evidenciar la acción de diversos factores evolutivos. Aplicando un modelo coalescente se simuló el efecto de diferentes escenarios demográficos/evolutivos, que incluyen mutación, migración y crecimiento poblacional en la estimación del desequilibrio de ligamiento. Para esto, se tomaron 3 microsatélites totalmente ligados y 3 poblaciones con tamaños efectivos de 10000 a 20000 individuos. Se muestrearon 100 cromosomas en cada una de las 1000 simulaciones realizadas para detectar LD mediante la prueba exacta de Fisher. Se observa que en los escenarios planteados se establece un “pseudoequlibrio” de ligamiento con valores cercanos a los observados en las poblaciones naturales. Es posible que los “pseudoequilibrios” encontrados se extiendan a los loci autosómicos en poblaciones donde se encuentren situaciones similares a las descriptas.

    It is presented a methodology on empirical about any detailed simulation model. This kind of validation it is always related with an experimental case. The empirical validation has a residual sense, because the conclusions are based on comparison between simulated outputs and experimental measurements. This methodology will guide us to detect the fails of the simulation model. Furthermore, it can be used a guide in the design of posteriori experiments. Three steps can be well differentiated: - Sensitivity analysis. It can be made with a DSA, differential sensitivity analysis, and with a MCSA, Monte-Carlo sensitivity analysis. - Looking the optimal domains of the input parameters. It has been developed a procedure based on the Monte-Carlo methods and Cluster techniques, to find the optimal domains of these parameters. - Residual analysis. This analysis has been made on the time domain on the frequency domain, it has been used the correlation analysis and spectral analysis. As application of this methodology, it is presented the validation carried out on a thermal simulation model on buildings, ESP studying the behavior of building components on a Test Cell of LECE of CIEMAT.

In a first phase of the study, it is observed that the obtained results agree with the experience and, in a second phase, a parametric study to evaluate the efficiency of this type of components is carried out. The numerical simulation presents the advantage of carrying out these studies without necessity of building the real models, with the saving in cost and time that this supposes. In this work, it has been sought to contribute to the knowledge of the acoustic behaviour of different type of materials and devices that are used to improve the acoustic isolation and acoustic conditioning.

    Full Text Available In this paper, we introduce some relationships between elements coming from psychological referentials with the purpose of developing a referential framework for interpreting and understanding the actions that take place during school practices with computer simulations that include, in addition to concepts of the learning process of a particular discipline, concepts that refer to social relationships, not only interactions among people but also between people with to culture, social institutions and social structure. From a social constructivist approach is proposed to constitute the object of study in the system “person + tool” in the situated context in the learning of science in the school, in order to obtain categories that allow us investigate the strategic knowledge employed by the students when they use educational simulations and the influence of the latter in science learning. We believe that the study of the strategic knowledge performed by the students in science classes when they interact with computer simulations is an issue of the technological mediation of learning. For that reason, from the socio-historical perspective we have selected the following categories: instrumental mediation, the distributed character of cognition, the zone of proximal development and the situated character of cognition.En este trabajo se presentan algunas relaciones entre elementos provenientes de referenciales psicológicos a los fines de elaborar un marco referencial que permita interpretar y comprender las acciones que se realizan durante prácticas escolares con simulaciones computacionales que incluya, además de conceptos propios del proceso de aprendizaje de una disciplina particular, conceptos que refieran a las relaciones sociales, tanto interacciones entre personas como los vínculos de las personas con la cultura, las instituciones sociales y la estructura social.

    Full Text Available Actualmente se han desarrollado distintos tipos de archivos climáticos para su uso en simulaciones energéticas, cuyo origen depende principalmente de las estaciones meteorológicas, variables ambientales, algoritmos de interpolación y periodos considerados. En atención a esta diversidad cabe preguntarse cuáles son los más apropiados para su utilización en estudios de esta naturaleza para viviendas en Chile, y en particular, para la ciudad de Concepción. Se presenta un análisis comparativo, desarrollado en el contexto del proyecto Fondef D10I10251 , entre tres fuentes de archivos climáticos para Concepción, el primero obtenido a través de la página web de EERE, (U.S. DOE Energy Efficiency and Renewable Energy, el segundo desarrollado por Meteonorm y el último generado a través de los datos proporcionados por un centro de observación geodésica ubicado en Concepción (TIGO. Se puede observar que el origen y método de obtención de datos para la ciudad de Concepción en Chile puede generar diferencias en la demanda de un 24,8%, que en este caso corresponde a 41,34 kWh/m2.

    RESUMEN 

    El papel preponderante de la corriente de potasio sensitiva a Adenosin Trifosfato y su contribución a cambios electrofi siológicos que ocurren durante heterogeneidades y alteraciones fisicoquímicas debido a isquemia en la pared transmural cardíaca son aún debatidos. El objetivo de este trabajo fue estudiar la infl uencia de la activación de la hipoxia en la desestabilización del frente de onda eléctrico en pared transmural heterogénea en presencia de isquemia subepicárdica en un modelo computacional de tejido virtual. La taquicardia polimórfi ca obtenida de las simulaciones muestra que la activación de la hipoxia presenta un comportamiento antiarrítmico. La hiperkalemia es el principal agente capaz de generar bloqueo de conducción y alteraciones del segmento TQ y el segmento ST en los electrogramas obtenidos.

    The knowledge and simulation of the end users of the electric power is a very important factor for the electric power utilities, since they allow them the long term investment planning. Formerly the electric power utilities planned their growth in base of the demand. However, nowadays new tools have been developed that allow the Demand Side Management (DSM) to be made, which consists in analyzing the end user consumption and model it, in such a way that it saves energy and uses it efficiently. To segregate the consumption curve of the domestic users in function of its end uses, it is needed to consider several factors: climatic conditions, geographic location, type of dwelling, number and ages of the members of the family occupying it, type and number of existing electric home appliances, electric power demand and its efficiency, life habits, etc. From the above it is deducted that the end users consume electric power in different ways. Consequently, the knowledge of its behavior will allow to draw its consumption curve. This is possible through field measurements (user monitoring) and/or surveys (to ask the user when and how he uses his house hold electric devices and equipment). The results of such studies must be simulated, in order to generalize and characterize behaviors, in such a way as to have available options of operational scenarios of electric devices and equipment, in order to select potential energy and demand savings.

    A three-dimensional numerical model was adapted to study the circulation, stratification and mixing patterns inside the port of El Sauzal. Salinity, temperature and density field data were measured, showing that density variations were mainly due to the temperature field with a very small contribution from salinity. The model simulated surface currents and the temperature field. The simulation was compared against field data showing that the model reproduces satisfactorily the circulation, stratification and mixing patterns. Surface circulation and vertical mixing were mainly forced by the tide, although winds greater than 6 m s{sup -}1 became the main forcing of vertical mixing and surface circulation. The surface currents traveled outside the port during ebb tide and vice versa during flood tide; however, with winds greater than 6 m s{sup -}1, the surface velocity followed the wind direction. When a discharge of 0.2 m{sup 3} s{sup -}1 was introduced into the system, the simulation showed an increase of 0.5 cm s{sup -}1 in the surface current velocity, during ebb tide. The vertical temperature structure increased as much as the discharge temperature (17.2 degree centigrade). This result verifies that a controlled discharge could improve circulation and mixing, reducing the residence time and improving the levels of oxygen in the water. [Spanish] Con la finalidad de conocer el patron de circulacion, estratificacion y mezcla dentro del puerto de El Sauzal, se adapto un modelo numerico tridimensional. Paralelamente se obtuvieron datos hidrograficos en el puerto de El Sauzal, en los que se encontro a la temperatura como el agente que modifica el campo de densidad, ya que la salinidad tiene poca variacion en este sistema. Debido a lo anterior, el modelo simulo solamente el patron de distribucion de temperatura y corrientes. La simulacion fue validada con datos de campo, demostrando que el modelo reproduce adecuadamente el patron de circulacion, estratificacion y mezcla

    The use of solar passive strategies in buildings with large glazed areas such as new solar control coatings in windows are becoming more important and helpful recently, mainly because those developments can help to reduce heat gains and/or losses through transparent materials, reduce energy consumption, and improving the environment inside buildings. This paper presents an assessment of thermal performance in an office building with a SnS-Cu{sub x}S solar control coating and its influence on indoor conditions. The simulations consider climates of Mexico city and Ottawa as a good representation of two extremely conditions to asses the thermal behaviour inside offices, energy consumption, costs for air conditioning, and the influence of interior heat transfer coefficient correlations on energy consumption. The results are shown with and without the solar control coating adhered in a clear glass and in a double window configuration. The case of the system glass-film is the worst configuration as result of the high temperatures in the internal surface impacting the air point temperature and increasing the energy consumption. In general, the double glass configuration presents the best conditions, showing higher benefits for the case in Mexico City than the case of Ottawa. [Spanish] Resulta importante implementar estrategias pasivas en estudios de edificaciones con grandes areas de ventanas, como es la implementacion de nuevos materiales de control solar en vidrios que ayudan a reducir las ganancias y/o perdidas de calor a traves de los materiales transparentes, y asi reducir el consumo de energia y mejorar las condiciones del confort interior de los edificios. Este estudio realiza una evaluacion del funcionamiento termico de una pelicula selectiva de SnS-Cu{sub x}S que permite algunas ventajas termicas y opticas en el ambiente interno. Las simulaciones dinamicas consideran climas de la Ciudad de Mexico y Ottawa , con resultados que muestran las condiciones de confort

    The most important aspects of wind energy in Mexico, including the potential for generating electricity and the major projects planned are presented here. In particular, the generation costs are compared to those of other energy sources. The results from the simulation of a 100MW wind farm in the Tehuantepec Isthmus are also presented. In addition, the environmental impacts related to the wind farm in the mentioned zone are analyzed. Finally, some benefits of using Probabilistic Safety Analysis are discussed with respect to evaluating the risks associated with events that can occur in wind parks, being especially useful for design and maintenance of the parks and the wind turbines themselves. In particular, an event tree was developed to analyze possible accident sequences that could occur when the wind speed is too great. Also, fault trees were developed for each mitigating system considered, in order to determine the relative importance of the wind generator components to the failure sequences, in order to evaluate the yield of suggested improvements and the optimization of maintenance programs.

    The MCNP code is used to simulate the radiation transport taking as tools the transport physics of each particle, either photon, neutron or electron, and the generation of random numbers. Developed in the Los Alamos National Laboratory, this code has been used thoroughly with great success, because the results of the simulations are broadly validated with representative experiments. In the one present work the room of radiotherapy of the Institute Zacatecano of the Tumor it is simulated, located in the city of Zacatecas where one is Theratron 780C machine manufactured by MSD Nordion, with the purpose of estimating the contribution to the dose that would be received in different points of the structure, included three directly under the source. Three results of analytical calculations for points located at different distances from the source are presented, and they are compared against those obtained by the simulation. Its are also presented results for the simulation of 10 points more distributed around the source. (Author)

    This research was aimed at establishing the differences, if any, between traditional direct teaching and constructive teaching through the use of computer simulations and their effect on pre-service teachers. It's also intended to gain feedback on the users of these simulations as providers of constructive teaching and learning experiences. The experimental framework used a quantitative method with a descriptive focus. The research was guided by two hypothesis and five inquiries. The data was obtained from a group composed of twenty-nine students from a private Metropolitan University in Puerto Rico and elementary school pre-service teachers. They were divided into two sub-groups: experimental and control. Two means were used to collect data: tests and surveys. Quantitative data was analyzed through test "t" for paired samples and the non-parametric Wilcoxon test. The results of the pre and post tests do not provide enough evidence to conclude that using the simulations as learning tools was more effective than traditional teaching. However, the quantitative results obtained were not enough to reject or dismiss the hypothesis Ho1. On the other hand, an overall positive attitude towards these simulations was obtained from the surveys. The importance of including hands-on activities in daily lesson planning was proven and well recognized among practice teachers. After participating and working with these simulations, the practice teachers expressed being convinced that they would definitely use them as teaching tools in the classroom. Due to these results, hypothesis Ho2 was rejected. Evidence also proved that practice teachers need further professional development to improve their skills in the application of these simulations in the classroom environment. The majority of these practice teachers showed concern about not being instructed on important aspects of the use of simulation as part of their college education curriculum towards becoming teachers.

    Full Text Available The Immerse Boundary Method (IBM was used to evaluate the sediment transport over deformable beds. Large Eddy Simulation (LES procedures were used for the mathematical treatment of turbulence, and the advection-diffusion equation was used to calculate sediment concentration. The Finite Differences Method with staggered grid was applied for the numerical solution of the governing equations (filtered Navier-Stokes, Continuity and advection-diffusion equations. Spatial derivatives were discretized using second order centered differences. A second order explicit Adams-Bashforth scheme was used for the time evolution in the advection-diffusion equation, while a fourth order Adams-Bashforth scheme was used for the filtered Navier-Stokes equations. The numerical simulation reproduced flow structures like large eddies after the dune crests and counter-rotative vortices, which are important in sediment transport. Resuspension fluxes and sedimentation (dependent on particle concentration were calculated using equations proposed in this study. The deformations of the bed caused by erosion and deposition may be well followed through the present procedures, showing that this methodology is adequate to evaluate bed modifications and sediment transport in alluvial flows.Se utilizó el método de fronteras inmersas para evaluar el transporte de sedimentos en lechos deformables. Los procedimientos de la simulación de gran escala fueron utilizados para el tratamiento matemático de la turbulencia, y se utilizó la ecuación de advección-difusión para calcular la concentración de sedimentos. Se aplicó el método de diferencias finitas con malla desplazada para la solución numérica de las ecuaciones básicas (Navier-Stokes filtrado, continuidad y las ecuaciones de advección-difusión. Las derivadas espaciales fueron discretizadas mediante diferencias de segundo orden centrado. Se utilizó un esquema explícito de Adams-Bashforth de segundo orden para la evolución del tiempo en la ecuación de advección-difusión, mientras que un esquema Adams-Bashforth de cuarto orden fue utilizado para las ecuaciones de Navier-Stokes filtrado. La simulación numérica reproduce estructuras de flujo, como los remolinos grandes después de las crestas de las dunas y los vórtices contrarrotativos, que son importantes en el transporte de sedimentos. Los flujos de resuspensión y sedimentación (dependientes de la concentración de partículas se calcularon utilizando las ecuaciones propuestas en este estudio. Las deformaciones del lecho por la erosión y la deposición pueden ser bien seguidas a través de los procedimientos aquí presentados, que muestran que esta metodología es adecuada para evaluar las modificaciones del lecho y el transporte de sedimentos en los flujos aluviales.

      supplying ducts, were obtained, with a maximum discrepancy of 5.5 m/s between the data published by McKenty and Gravel (1997) and this analysis, for the case of combustion gases in the interior of the furnace. Temperature profiles were obtained, which were overestimated in the order of 417 Celsius degrees for the case of the temperature of gases in the center of the combustion chamber, when comparing them with the corresponding ones obtained by McKenty and Gravel (1997). It is speculated that this discrepancy must to be due to the omission of the connection of the radiation model to the global computational model and; the contours of concentration of species for the combustion products in the chamber were considered (carbon dioxide, oxygen and nitrogen), obtaining only the qualitative behavior of these. It is proposed as conclusion that the computational model developed in this thesis work can be used for the estimation of flow of fluids patterns, heat transference and transference of mass of a steam generator VU-60 of the tangential type and similar to the one taken as a base for this analysis. One improvement to the computational model developed could be achieved including the radiation effect, which requires a larger memory capacity of the computer hardware than the one available during the elaboration of this thesis.

      We investigated the damping of coronal sausage modes, considering initial nonlinear states and inhomogeneous media. We simulate two observational cases, associated with flares described in Asai et al. and Melnikov et al. The two cases are able to develop fundamental and trapped sausage modes. We conclude that if we allow small pressure jumps between the corona and the loop, as determined by the relations of Rankine­Hugoniot, we obtain a non- dissipative damping of the modes, which until now has not been explored.

Debido a esto, muchos paises estan investigando nuevas tecnologias alternas para su sustitucion. Uno de los principales tecnologias propuestas son los transformadores de calor. Estos equipos son capaces de ahorrar energia calorifica principalmente en procesos industriales. Debido a esto, estas tesis realiza estudios teoricos de transformadores de calor en procesos industriales tipicos de la region como es la destilacion de derivados de petroleo y refinacion de azucar morena, para observar la energia que puede ser ahorrada por el uso de estos equipos. Por otra parte se realizo una evaluacion experimental de un transformador de calor con aditivos debido a que aumentan la absorcion en el absorbedor, mejorando el coeficiente de operacion. En la simulacion de la columna de destilacion de petroleo se utilizo el simulador de procesos quimicos Aspen Plus version 9.3-2, debido a que este tiene modelos termodinamicos muy confiables para estudiar el comportamiento de cada uno de sus componentes. Los resultados mostraron que con el transformador de calor de una etapa operando con la mezcla LiBr-H{sub 2} O se puede ahorrar hasta un 45% de la energia suministra a la caldera y hasta un 32% con el transformador de doble absorcion. Para la modelacion de la refineria del azucar morena se uso el paquete Visual Basic, version 6.2. El paquete fue utilizado debido a que es un lenguaje grafico y de facil manejo. Los resultados mostraron que se puede recuperar hasta un 15% de la energia suministrada a la caldera. En la experimentacion se utilizo la mezcla bromuro de litio-agua y bromuro de

      conocimiento en filtros activos de potencia usados en los puntos de acoplamiento comun entre las fuentes de C.A. y las cargas no lineales formadas por convertidores estaticos de CA/CD, para la supresion de corrientes armonicas y compensacion instantanea de la potencia reactiva. Partiendo de los filtros activos que solo afectan las tres corrientes balanceadas de los sistemas trifasicos de 3 hilos, se llega al tema de esta tesis, cuyo objetivo es resolver el problema de la compensacion reactiva y supresion de corrientes armonicas tanto en las tres fases como tambien en el neutro de los sistemas trifasicos de 4 hilos. La contribucion principal de esta tesis es el diseno, analisis y simulacion de un filtro activo que ademas de suprimir corrientes armonicas y compensacion del factor de potencia en las tres fases de un sistema trifasico desbalanceado, tambien tiene la capacidad para remover la corriente que circula en el neutro, debido al desbalance de las corrientes de fase. Este diseno se basa en la extension de la teoria de la potencia reactiva instantanea que incluye la existencia de los componentes de secuencia cero en las corrientes de fase. Se propone en la tesis un novedoso filtro basado en un inversor trifasico de 4 ramas, 3 ramas de fase y una rama de neutro, que hasta el mejor conocimiento del autor no ha sido reportado en la literatura. Se hace uso de un numero extenso de resultados de simulacion para probar la validez de este filtro, cuyo comportamiento es superior a los filtros para supresion de corrientes en el neutro existentes en la literatura, de los cuales tambien se presenta un estudio comparativo. La tesis tambien incluye un analisis matematico y grafico de los componentes simetricos en sistemas balanceados y desbalanceados a efecto de conocer la naturaleza de las corrientes armonicas de secuencia cero. Se incluye un apartado sobre causas y efectos del problema de la contaminacion armonica.

      The application of X-ray diffraction (XRD) in the study of crystalline structures of the natural and modified zeolites allows the identification, lattice parameter determination and the crystallinity grade of the sample of interest. Until two decades ago, simulation methods of X-ray diffraction patterns were developed with which was possible to do reliable determinations of their crystalline structure. In this work it is presented the first stage of the crystalline structure simulation of zeolitic material from Etla, Oaxaca which has been studied for using it in the steam production industry and purification of industrial water. So that the natural material was modified for increasing its sodium contents and this material in its turn was put in contact with aqueous solutions of Na, Mg and Ca carbonates. All the simulations were done with the Lazy-Pulverix method. The considered phase was clinoptilolite. It was done the comparison with three clinoptilolite reported in the literature. (Author)

      Son muchos los escenarios astrofísicos en que los procesos hidrodinámicos juegan un papel clave. En la complejidad que encierra la descripción de dichos procesos destaca el de la correcta simulación de flujos complejos donde la presencia de ondas de choque fuertes que, eventualmente, interaccionan entre ellas o también la presencia de inestabilidades (Kelvin-Helmholtz, Rayleigh-Taylor, etc.) suponen un verdadero desafío numérico. Los códigos hidrodinámicos basados en la solución de un problema de valores iniciales discontinuo (problema de Riemann) son, en la actualidad, los más robustos en el campo de la dinámica de fluidos computacional. En esta charla se dará un resumen de los fundamentos de dichas técnicas numéricas (esquemas de alta resolución de captura de choques) y se ilustrará su potencialidad mostrando una amplia gama de resultados en diferentes aplicaciones astrofísicas.

      The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion.

      Piepel, Gregory F.

      2007-12-01

      A mixture experiment involves combining two or more components in various proportions or amounts and then measuring one or more responses for the resulting end products. Other factors that affect the response(s), such as process variables and/or the total amount of the mixture, may also be studied in the experiment. A mixture experiment design specifies the combinations of mixture components and other experimental factors (if any) to be studied and the response variable(s) to be measured. Mixture experiment data analyses are then used to achieve the desired goals, which may include (i) understanding the effects of components and other factors on the response(s), (ii) identifying components and other factors with significant and nonsignificant effects on the response(s), (iii) developing models for predicting the response(s) as functions of the mixture components and any other factors, and (iv) developing end-products with desired values and uncertainties of the response(s). Given a mixture experiment problem, a practitioner must consider the possible approaches for designing the experiment and analyzing the data, and then select the approach best suited to the problem. Eight possible approaches include 1) component proportions, 2) mathematically independent variables, 3) slack variable, 4) mixture amount, 5) component amounts, 6) mixture process variable, 7) mixture of mixtures, and 8) multi-factor mixture. The article provides an overview of the mixture experiment designs, models, and data analyses for these approaches.

      Vanschoren, Joaquin; Blockeel, Hendrik

      Next to running machine learning algorithms based on inductive queries, much can be learned by immediately querying the combined results of many prior studies. Indeed, all around the globe, thousands of machine learning experiments are being executed on a daily basis, generating a constant stream of empirical information on machine learning techniques. While the information contained in these experiments might have many uses beyond their original intent, results are typically described very concisely in papers and discarded afterwards. If we properly store and organize these results in central databases, they can be immediately reused for further analysis, thus boosting future research. In this chapter, we propose the use of experiment databases: databases designed to collect all the necessary details of these experiments, and to intelligently organize them in online repositories to enable fast and thorough analysis of a myriad of collected results. They constitute an additional, queriable source of empirical meta-data based on principled descriptions of algorithm executions, without reimplementing the algorithms in an inductive database. As such, they engender a very dynamic, collaborative approach to experimentation, in which experiments can be freely shared, linked together, and immediately reused by researchers all over the world. They can be set up for personal use, to share results within a lab or to create open, community-wide repositories. Here, we provide a high-level overview of their design, and use an existing experiment database to answer various interesting research questions about machine learning algorithms and to verify a number of recent studies.

      My name is Nicoara Floarea and I am teacher at Secondary School Calatele and I teach students from preparatory class and the second grade . They are six-eight years old. In my activity, for introducing scientific concepts to my students, I use various and active methods or traditional methods including experiments. The experiment stimulates students' curiosity, their creativity, the understanding and knowledge taught accessibility. I propose you two such experiments: The life cycle of the plants (long-term experiment, with rigorous observation time):We use beans, wheat or other; They are grown in pots and on the cotton soaked with water,keeping under students' observation protecting them ( just soak them regularly) and we waiting the plants rise. For discussions and comments of plant embryo development we use the plants which rose on the cotton soaked with water plants at the end of the first week. Last school year we had in the pot climbing beans which in May made pods. They were not too great but our experiment was a success. The students could deduce that there will develop those big beans which after drying will be planted again. The influence of light on plants (average duration experiment with the necessary observation time): We use two pots in which plants are of the same type (two geraniums), one of them is situated so as to get direct sunlight and other plant we put in a closed box. Although we wet both plants after a week we see that the plant that benefited from sunlight has turned strain in direct sunlight, developing normally in return the plant out of the box I have yellowed leaves, photosynthesis does not She has occurred . Students will understand the vital role of the Sun in plants' life, both in the classroom and in nature. The experiment is a method of teaching students extremely pleasant, with a remarkable percentage of acquiring more knowledge.

      The main objective of DIRAC experiment is the measurement of the lifetime {tau} of the exotic hadronic atom consisting of {pi}{sup +} and {pi}{sup -} mesons. The lifetime of this atom is determined by the decay mode {pi}{sup +} {pi}{sup -} {yields} {pi}{sup 0} {pi}{sup 0} due to the strong interaction. Through the precise relationship between the lifetime and the S-wave pion-pion scattering length difference |a{sub 0} - a{sub 2}| for isospin 0 and 2 (respectively), a measurement of {tau} with an accuracy of 10% will allow a determination of |a{sub 0} - a{sub 2}| at a 5% precision level. Pion-pion scattering lengths have been calculated in the framework of chiral perturbation theory with an accuracy below 5%. In this way DIRAC experiment will provide a crucial test of the chiral symmetry breaking scheme in QCD effective theories at low energies.

At the same time design experiments are also useful for evaluating the empirical validity of theoretical arguments and the further development of these arguments in the light of empirical evidence (by using e.g. the technique of pattern matching. We describe how we have applied this methodology in two cases and discuss our research approach. We encountered some unexpected difficulties, especially in the cooperation with professionals and citizens. These difficulties complicate the valid attribution of causal effects to the use of the new instrument. However, our preliminary conclusion is that design experiments are useful in our field of study

      In 1987, Westinghouse Hanford Company began operating a first-generation integrated safeguards system in the Plutonium Finishing Plant storage vaults. This Vault Safety and Inventory System is designed to integrate data into a computer-based nuclear material inventory monitoring system. The system gathers, in real time, measured physical parameters that generate nuclear material inventory status data for thousands of stored items and sends tailored report to the appropriate users. These data include canister temperature an bulge data reported to Plant Operations and Material Control and Accountability personnel, item presence and identification data reported to Material Control and Accountability personnel, and unauthorized item movement data reported to Security response forces and Material Control and Accountability personnel. The Westinghouse Hanford Company's experience and operational benefits in using this system for reduce radiation exposure, increase protection against insider threat, and real-time inventory control are discussed in this paper

      Full Text Available The paper presents the results of the survey about the changes in modern management, identified from the experience of Romanian managers. By this online study one presents both the obstacles encountered and the recommendations for such a type of management that the present and future mangers must take into account. What motivated the respondent Romanian managers most to open their own business is the independence it offered them. They work in the field they have liked since they were young. The second reason was the perspective to have an additional income from the business development. The third argument in favour of opening a business is the possibility to assure the balance between personal life and career.

      The LEAP simulation model requires the values of some exogenous variables: At international level, the population increase, the economic growth and the international oil prices; at domestic level, the population increase, the economic growth, the energy intensity, the elasticity of demand of energy-price, and the elasticity of energy demand-gross national product. The use of the LEAP model for the estimation of the penetration of the renewable energies in Mexico comprises of the requirements established in the study. To estimate the future long term values of variables as the exogenous ones required by this model by means of expert opinion can be, given the nature of same, equally or more complicated and speculative than to directly consider the future rates of penetration of the renewable energies. In order to reflect on the future values of these variables a group of approach with experts was integrated. [Spanish] El modelo de simulacion LEAP requiere los valores de algunas variables exogenas: A nivel internacional, el crecimiento demografico, el crecimiento economico y los precios internacionales del petroleo; a nivel nacional, el crecimiento demografico, el crecimiento economico, la intensidad energetica, la elasticidad de demanda de energia-precio, y la elasticidad de demanda de energia-producto interno bruto. El uso del modelo LEAP para la estimacion de la penetracion de las energias renovables en Mexico forma parte de los requerimientos establecidos en el estudio. Estimar los futuros valores a largo plazo de variables como las exogenas requeridas por dicho modelo mediante opinion experta puede resultar, dada la naturaleza de las mismas, tan o mas complicado y especulativo que estimar las futuras tasas de penetracion de las energias renovables directamente. Para reflexionar sobre los futuros valores de dichas variables se integro un grupo de enfoque con expertos.

      In Europe an initiative for the reduction of uncertainties in severe accident safety issues was initiated. Generally, the error made in predicting plant behaviour is called uncertainty, while the discrepancies between measured and calculated trends related to experimental facilities are called the accuracy of the prediction. The purpose of the work is to assess the accuracy of the calculations of the severe accident International Standard Problem ISP-46 (Phebus FPT1), performed with two versions of MELCOR 1.8.5 for validation purposes. For the quantitative assessment of calculations the improved fast Fourier transform based method (FFTBM) was used with the capability to calculate time dependent code accuracy. In addition, a new measure for the indication of the time shift between the experimental and the calculated signal was proposed. The quantitative results obtained with FFTBM confirm the qualitative conclusions made during the Jozef Stefan Institute participation in ISP-46. In general good agreement of thermal-hydraulic variables and satisfactory agreement of total releases for most radionuclide classes was obtained. The quantitative FFTBM results showed that for the Phebus FPT1 severe accident experiment the accuracy of thermal-hydraulic variables calculated with the MELCOR severe accident code is close to the accuracy of thermal-hydraulic variables for design basis accident experiments calculated with best-estimate system codes.

      Full Text Available The administration of behavioral and experimental paradigms for psychology research is hindered by lack of a coordinated effort to develop and deploy standardized paradigms. While several frameworks (de Leeuw (2015; McDonnell et al. (2012; Mason and Suri (2011; Lange et al. (2015 have provided infrastructure and methods for individual research groups to develop paradigms, missing is a coordinated effort to develop paradigms linked with a system to easily deploy them. This disorganization leads to redundancy in development, divergent implementations of conceptually identical tasks, disorganized and error-prone code lacking documentation, and difficulty in replication. The ongoing reproducibility crisis in psychology and neuroscience research (Baker (2015; Open Science Collaboration (2015 highlights the urgency of this challenge: reproducible research in behavioral psychology is conditional on deployment of equivalent experiments. A large, accessible repository of experiments for researchers to develop collaboratively is most efficiently accomplished through an open source framework. Here we present the Experiment Factory, an open source framework for the development and deployment of web-based experiments. The modular infrastructure includes experiments, virtual machines for local or cloud deployment, and an application to drive these components and provide developers with functions and tools for further extension. We release this infrastructure with a deployment (http://www.expfactory.org that researchers are currently using to run a set of over 80 standardized web-based experiments on Amazon Mechanical Turk. By providing open source tools for both deployment and development, this novel infrastructure holds promise to bring reproducibility to the administration of experiments, and accelerate scientific progress by providing a shared community resource of psychological paradigms.

      Set to begin data taking at the end of 2018, the Belle II experiment is the next-generation B-factory experiment hosted at KEK in Tsukuba, Japan. The experiment represents the cumulative effort from the collaboration of experimental and detector physics, computing, and software development. Taking everything learned from the previous Belle experiment, which ran from 1998 to 2010, Belle II aims to probe deeper than ever before into the field of heavy quark physics. By achieving an integrated luminosity of 50 ab−1 and accumulating 50 times more data than the previous experiment across its lifetime, along with a rewritten analysis framework, the Belle II experiment will push the high precision frontier of high energy physics. This paper will give an overview of the key components and development activities that make the Belle II experiment possible.

    10. Diagnostics for pellet experiments

      Johnson, R.R.

      1978-01-01

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

      In this paper a new model for heat balance of a window is proposed. The objective of the model is to solve accurately the heat balance on a single glass window in a moderate climate. This procedure will allow the designer to calculate the main parameters of a fenestration (surface, orientation, overhangs, etc.), minimizing the energy consumption for a specific enclosure (including heating, air conditioning and lighting). The present study is mainly focused on problems related with the internal long wave radiation calculations, and secondly on the effect of internal convection coefficient on the heat balance. A comparison between the results obtained using this model and those obtained with other current models is included in the second part of the paper. The importance of using the right internal convection coefficient on the heat balance of fenestration for this kind of application is also analyzed. (author)

      Muñoz-Caro, Guillermo Manuel

      Las nubes moleculares son regiones de formación de estrellas, con temperaturas cinéticas entre 10-50 K y densidades de 103-106 átomos cm-3. Su materia está formada por gas y polvo interestelar. Estas partículas de polvo están cubiertas por una fina capa de hielo, de unos 0.01 μm, que contiene H2O y a menudo CO, CO2, CH3OH y NH3. El hielo es presumiblemente irradiado por fotones ultravioleta y rayos cósmicos en las zonas poco profundas de las nubes moleculares y las regiones circunestelares. En un sistema de vacío, P ˜ 10-7 mbar, simulamos la deposición de hielo a partir de 10 K y la irradiación ultravioleta por medio de una lámpara de descarga de hidrógeno activada con microondas. La evolución del hielo se observa por medio de un espectrómetro infrarrojo. De este modo es posible determinar la composición del hielo observado en el medio interestelar y predecir la presencia de moléculas aún no detectadas en el espacio, que han sido producto del procesamiento del hielo en nuestros experimentos. También es posible calentar el sistema hasta temperatura ambiente para sublimar el hielo depositado. Cuando el hielo ha sido previamente irradiado, se observa un residuo compuesto por moléculas orgánicas complejas, algunas prebióticas, como varios ácidos carboxílicos, aminas, amidas, ésteres y en menor proporción moléculas heterocíclicas y aminoácidos. Algunas de estas moléculas podrían detectarse en estado gaseoso por medio de observaciones milimétricas y de radio. También podrían estar presentes en el polvo cometario, cuyo análisis químico está planeado por las misiones Stardust y Rosetta. Mientras tanto, nuestro grupo está llevando a cabo el análisis de partículas de polvo interplanetario (IDPs), algunas de las cuales pueden ser de origen cometario. Al igual que ocurre con los productos obtenidos por irradiación del hielo en nuestros experimentos, algunas IDPs son ricas en material orgánico que contiene oxígeno.

Hablar de la educación hoy, y aquí, es hablar de una crisis, de una incertidumbre, de una inquietud, que se traduce sin duda en el trabajo cotidiano cuando se pone el cuerpo, cada día, atravesados por todas las dudas y dificultades sobre el sentido y el sin sentido de lo que se hace o se deja de hacer, y que se traduce también cuando es necesario juntar los cuerpos y ayunar en una carpa, ...

      2014-02-01

      Due to the problems with the environment and other issues arising from the use of oil as the main source of energy, such as unstable politics and economics, there has been a growing interest in the development of alternative forms of energy over the last few years. In this field, the sun is a fundamental element, since any form of existing energy derives from it, directly or indirectly. Taking in to consideration all of these renewable energies, we have decided to focus on solar thermal energy, seeing as it will play a vital role in the future particularly in countries such as Spain that have great solar potential. Amid this form of renewable energy, the parabolic cylinder concentrator power plants are technologies with one of the most promising futures. Power plants with sufficient technological developments to compete with the other forms of energies and that have an extensive margin for improvement. These power plants are the subject of the investigations carried out in this project. This project will try to establish and standardize some of the necessary procedures for the process of data prior to the simulation of energy with these types of power plants. The final objective is to help create a regulation where all these procedures are gathered together, and one that can be used as a guide for future investigations on the viability of these power plants. To achieve this, this project is comprised of various phases where different necessary investigations will be carried out in order to define the different points of the regulation. Firstly, the different casuistries will be investigated when analyzing the behavior of the estimated input data. At this stage, the selected variable (global or direct radiation), as well as the procedure used for the generation of the Monthly Reference Value, will be taken in to account, differentiating it in to two different typologies. The best method for the adjustment of the estimated data obtained from the satellite images will also be investigated, proposing the incorporation of a new method for it, as well as trying to determine whether it is equivalent to the one already established. Lastly, a simulation will be completed with the estimated data already processed in order to evaluate the influence of different alternatives and methods set out in the results, allowing for the comparison of these results with other simulations carried out with the measured data.

      Among the materials to be used on the tritium generator cover of the future fusion reactors the lithium aluminate ({gamma} - LiAlO{sub 2}) is one of the more studied. In this work it is presented the superlattice structural simulation that presents to {gamma} - LiAlO{sub 2} as main phase and to {alpha} - LiAlO{sub 2} as the secondary phase. The simulation is developed considering that as the two phases present different symmetry ({gamma} - LiAlO{sub 2} is tetrahedral and {alpha} - LiAlO{sub 2} is hexahedral) it is had a superlattice LUCS type (Layered Ultrathin Coherent Structure) that is it presents an structure in coherent ultrathin layers since it is what implicates a lesser energy of formation.

      Olesen, Henning Salling

      2017-01-01

      Abstract: This chapter introduces a psycho-societal approach to theorizing learning, combining a materialist theory of socialization with a hermeneutic interpretation methodology. The term "approach" indicates the intrinsic connection between theory, empirical research process and epistemic subject....... Learning is theorized as dynamic subjective experience of (socially situated) realities, counting on individual subjectivity as well as subjective aspects of social interaction. This psycho-societal theory of subjective experiences conceptualizes individual psychic development as interactional experience...... of societal relations, producing an inner psycho-dynamic as a conscious and unconscious individual resource in future life. The symbolization of immediate sensual experiences form an individual life experience of social integration, language use being the medium of collective, social experience (knowledge...

    3. Experiment, right or wrong

      Franklin, Allan

      2008-01-01

      In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

      This report describes two experiments in which SBS would be expected to play an important role. In the first experiment, we find a clear signature of the Brillouin backscatter of a short (100 psec) pulse from a long (approx. 50 μm) gradient length gas target plasma. The second experiment used much longer (approx. 1 nsec) pulses on spherical glass shell targets. These experiments were done with both narrow ( 30A) bandwidth laser light. Using one-dimensional, spherically symmetric fluid simulations, we have attempted to model many of the laser-plasma interaction processes which combine to determine the amount of absorbed energy in the long-pulse experiments. These simulations indicate that modest laser bandwidths are successful in reducing the level of SBS at the irradiances ( 15 W/cm 2 ) used in these experiments

    10. Molybdenum solar neutrino experiment

      International Nuclear Information System (INIS)

      Wolfsberg, K.; Cowan, G.A.; Bryant, E.A.

      1984-01-01

      The goal of the molybdenum solar neutrino experiment is to deduce the 8 B solar neutrino flux, averaged over the past several million years, from the concentration of 98 Tc in a deeply buried molybdenum deposit. The experiment is important to an understanding of stellar processes because it will shed light on the reason for the discrepancy between theory and observation of the chlorine solar neutrino experiment. Possible reasons for the discrepancy may lie in the properties of neutrinos (neutrino oscillations or massive neutrinos) or in deficiencies of the standard solar model. The chlorine experiment only measures the 8 B neutrino flux in current times and does not address possible temporal variations in the interior of the sun, which are also not considered in the standard model. In the molybdenum experiment, we plan to measure 98 Tc (4.2 Myr), also produced by 8 B neutrinos, and possibly 97 Tc (2.6 Myr), produced by lower energy neutrinos

High Energy Physics experiments have frequently adopted cryogenic versions of their apparatus to achieve optimal performance, and those for the LHC will be no exception. The two largest experiments for CERN's new flagship accelerator, ATLAS and CMS, will both use large superconducting magnets operated at 4.5 Kelvin - almost 270 degrees below the freezing point of water. ATLAS also includes calorimeters filled with liquid argon at 87 Kelvin. For the magnets, the choice of a cryogenic version was dictated by a combination economy and transparency to emerging particles. For the calorimeters, liquid argon was selected as the fluid best suited to the experiment's physics requirements. High Energy Physics experiments are the result of worldwide collaborations and...

      1992-01-01

      A sequence of reactor and related experiments has been a central element of a senior-level laboratory course at Pennsylvania State University (Penn State) for more than 20 yr. A new experiment has been developed where the students program and operate a computer controller that manipulates the speed of a secondary control rod to regulate TRIGA reactor power. Elementary feedback control theory is introduced to explain the experiment, which emphasizes the nonlinear aspect of reactor control where power level changes are equivalent to a change in control loop gain. Digital control of nuclear reactors has become more visible at Penn State with the replacement of the original analog-based TRIGA reactor control console with a modern computer-based digital control console. Several TRIGA reactor dynamics experiments, which comprise half of the three-credit laboratory course, lead to the control experiment finale: (a) digital simulation, (b) control rod calibration, (c) reactor pulsing, (d) reactivity oscillator, and (e) reactor noise

      2007-02-01

      Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention.

      In November, 1991, at the JET tokamak in Abingdon, the U.K., DT plasma combustion experiment was carried out for the first time in history. The output power by nuclear fusion of 1.7 MW at maximum and the total power output of 2 MJ were attained, and it was proved that the controlled nuclear fusion accompanied by considerable power output can be carried out on the ground as a real thing. One milestone of the dream and target of nuclear fusion reactors was attained. In this paper, the results of the experiment are reported, and their meaning for the research of hereafter is considered. In the experiment this time, 0.24 g of tritium in total was used, including conditioning. The last two shots became the power output experiment of MW class nuclear fusion reaction, in which about 13% of tritium fuel ratio was estimated. The preliminary tritium experiment was divided into six phases, and was carried out for three weeks, aiming at collecting the basic data for the full scale DT experiment. The examination of the research program, the preliminary tritium experiment and the success of the PTE and the new development are described. (K.I.)

      2018-01-01

      Online labor markets provide new opportunities for behavioral research, but conducting economic experiments online raises important methodological challenges. This particularly holds for interactive designs. In this paper, we provide a methodological discussion of the similarities and differences between interactive experiments conducted in the laboratory and online. To this end, we conduct a repeated public goods experiment with and without punishment using samples from the laboratory and the online platform Amazon Mechanical Turk. We chose to replicate this experiment because it is long and logistically complex. It therefore provides a good case study for discussing the methodological and practical challenges of online interactive experimentation. We find that basic behavioral patterns of cooperation and punishment in the laboratory are replicable online. The most important challenge of online interactive experiments is participant dropout. We discuss measures for reducing dropout and show that, for our case study, dropouts are exogenous to the experiment. We conclude that data quality for interactive experiments via the Internet is adequate and reliable, making online interactive experimentation a potentially valuable complement to laboratory studies.

    18. Temporal Experience and Metaphysics

      Directory of Open Access Journals (Sweden)

      Graham Peebles

      Full Text Available ABSTRACT The well-known phenomenological argument draws metaphysical conclusions about time, specifically about change through time and the resulting passage or flow of time, from our temporal experience. The argument begins with the phenomenological premise that there is a class of properties which underlies our experience of time and change through time, and its conclusion is that these properties are not merely experienced but exemplified. I argue that the phenomenological argument is best served by the adoption of a representational theory of perception. I then present a representational theory of temporal experience.

      Søndergaard, Morten

      to identify and locate the experiments of POEX65 as acts; and to ask the questions: what constitutes those acts as experiments? and how do we possibly archive them? My purpose, then, is to define the methodologies to obtain the contours of a post-phenomenology of experimental artistic production in order...... to be able to analyse the phenomena found at POEX65. Here I will use the notion of the ‘ontological theatre’ (Pickering), which, according to Pickering, is acted out in experimental art productions. The experiment could thus be seen as an ‘agency-realism’ – as an ‘act’ of relations across the aesthetics...

      The Red Sage campaign is a series of subcritical dynamic plutonium experiments designed to measure ejecta. Nightshade, the first experiments in Red Sage scheduled for fiscal year 2019, will measure the amount of ejecta emission into vacuum from a double-­shocked plutonium surface. To address the major technical risks in Nightshade, a Level 2 milestone was developed for fiscal year 2016. Silverleaf, a series of four experiments, was executed at the Los Alamos National Laboratory in July and August 2016 to demonstrate a prototype of the Nightshade package and to satisfy this Level 2 milestone. This report is documentation that Red Sage Level 2 milestone requirements were successfully met.

      A series of atmospheric aerosol diffusion experiments combined with lidar detection was conducted to evaluate and calibrate an existing retrieval algorithm for aerosol backscatter lidar systems. The calibration experiments made use of two (almost) identical mini-lidar systems for aerosol cloud...... detection to test the reproducibility and uncertainty of lidars. Lidar data were obtained from both single-ended and double-ended Lidar configurations. A backstop was introduced in one of the experiments and a new method was developed where information obtained from the backstop can be used in the inversion...... algorithm. Independent in-situ aerosol plume concentrations were obtained from a simultaneous tracer gas experiment with SF6, and comparisons with the two lidars were made. The study shows that the reproducibility of the lidars is within 15%, including measurements from both sides of a plume...

      CERN. Geneva

      2003-01-01

      A neutrino factory based on a muon storage ring is the ultimate tool for studies of neutrino oscillations, including possibly leptonic CP violation. It is also the first step towards muon colliders. The performance of this new and promising line of accelerators relies heavily on the concept of ionisation cooling of minimum ionising muons, for which much R&D is required. The concept of a muon ionisation cooling experiment has been extensively studied and first steps are now being taken towards its realisation by a joint international team of accelerator and particle physicists. The aim of the workshop is to to explore at least two versions of an experiment based on existing cooling channel designs. If such an experiment is feasible, one shall then select, on the basis of effectiveness, simplicity, availability of components and overall cost, a design for the proposed experiment, and assemble the elements necessary to the presentation of a proposal. Please see workshop website.

      The Northfield Experiments took place at Hollymoor Hospital, Northfield, Birmingham, during World War II. The first experiment was conducted by Bion & Rickman. The second evolved gradually; many people contributed to its success, including Foulkes, Main and Bridger. The experiments were an important landmark in the evolution of theory and practice in group psychotherapy and in the therapeutic community movement. They were not carried out solely as responses to the need for mass treatment of neurotic disorders among army personnel; antecedent factors, the theoretical orientation of the practitioners and the nature of army life were equally important. The two experiments differed in pace and in recognition of the needs of higher-order systems, particularly the military hierarchy. They shared many underlying concepts, including responsibility to society, the therapeutic use of groups (including the hospital community) and an emphasis on process. Lessons learned at Northfield remain relevant to the practice of psychiatry today.

      The present study develops a set of 10 dimensions based on a systematic understanding of the concept of experience as a holistic psychological. Seven of these are derived from a psychological conception of what experiencing and experiences are. Three supplementary dimensions spring from...... the observation that experiences apparently have become especially valuable phenomena in Western societies. The 10 dimensions are tried out in a field study at the Center for Art and Media (ZKM) in Germany with the purpose to study their applicability in the evaluation of interactive sound archives. 29 walk......-alongs were carried out with 58 museums visitors. Our analysis showed that it was possible to identify the 10 experience dimensions in the study material. Some dimensions were expressed more frequently than others. The distribution of expressed dimensions and the content of the user comments provided a clear...

      The rotational component of the CMB polarization, the so-called B-modes, is one of the major topic for next generation CMB experiments. This signal traces the effect on the CMB due to primordial gravitational waves produced during the inflationary epoch, probing the physics of the very early universe at GUT energy scales. This is a challenge, being the expected amplitude of B-mode polarization ~ 0.1μK. In this paper we describe the BRAIN experiment, a bolometric interferometer which combines high sensitivity bolometric detectors with the excellent control of systematic effects proper of interferometers. Being a ground based experiment, we identified Dome Charlie in Antarctica as the best site for such measurements. In order to validate the goodness of the site, as well as some of the implemented technical solutions, we built a pathfinder experiment which has been successfully operated during last Antarctic summer, and we report about preliminary results obtained.

      Every 21st century student is expected to develop science literacy skills. As this is not part of Serbian national curriculum yet, we decided to introduce it with this project. Experiment-o-mania provides students to experience science in different and exciting way. It makes opportunity for personalized learning offering space and time to ask (why, where, how, what if) and to try. Therefore, we empower young people with skills of experimenting, and they love science back. They ask questions, make hypothesis, make problems and solve them, make mistakes, discuss about the results. Subsequently this raises the students' interest for school curriculum. This vision of science teaching is associated with inquiry-based learning. Experiment-o-mania is the unique and recognizable teaching methodology for the elementary school Drinka Pavlović, Belgrade, Serbia. Experiment-o-mania implies activities throughout the school year. They are held on extra class sessions, through science experiments, science projects or preparations for School's Days of science. Students learn to ask questions, make observations, classify data, communicate ideas, conduct experiments, analyse results and make conclusions. All science teachers participate in designing activities and experiments for students in Experiment-o-mania teaching method. But they are not alone. Teacher of fine arts, English teachers and others also take part. Students have their representatives in this team, too. This is a good way to blend knowledge among different school subject and popularize science in general. All the experiments are age appropriate and related to real life situations, local community, society and the world. We explore Fibonacci's arrays, saving energy, solar power, climate change, environmental problems, pollution, daily life situations in the country or worldwide. We introduce great scientists as Nikola Tesla, Milutin Milanković and sir Isaac Newton. We celebrate all relevant international days, weeks

Kirkby shows a sketch to illustrate the possible link between galactic cosmic rays and cloud formations. The CLOUD experiment uses beams from the PS accelerator at CERN to simulate the effect of cosmic rays on cloud formations in the Earth's atmosphere. It is thought that cosmic ray intensity is linked to the amount of low cloud cover due to the formation of aerosols, which induce condensation.

      Tedre, Matti; Moisseinen, Nella

      2014-01-01

      Experiments play a central role in science. The role of experiments in computing is, however, unclear. Questions about the relevance of experiments in computing attracted little attention until the 1980s. As the discipline then saw a push towards experimental computer science, a variety of technically, theoretically, and empirically oriented views on experiments emerged. As a consequence of those debates, today's computing fields use experiments and experiment terminology in a variety of ways. This paper analyzes experimentation debates in computing. It presents five ways in which debaters have conceptualized experiments in computing: feasibility experiment, trial experiment, field experiment, comparison experiment, and controlled experiment. This paper has three aims: to clarify experiment terminology in computing; to contribute to disciplinary self-understanding of computing; and, due to computing's centrality in other fields, to promote understanding of experiments in modern science in general.

      In this article, I explore the meaning of experiments in early twentieth century psychology, focusing on the qualitative experimental methodology of psychologist Frederic BARTLETT. I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which...... was in a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology. The contrast is further explored by reviewing the history of "replications...

      The Bates large acceptance spectrometer toroid (BLAST) experiment was operated at the MIT-Bates Linear Accelerator Center from 2003 until 2005. The detector and experimental program were designed to study, in a systematic manner, the spin-dependent electromagnetic interaction in few-nucleon systems. As such the data will provide improved measurements for neutron, proton, and deuteron form factors. The data will also allow details of the reaction mechanism, such as the role of final state interactions, pion production, and resonances to be studied. The experiment used: a longitudinally polarized electron beam stored in the South Hall Storage Ring; a highly polarized, isotopically pure, internal gas target of hydrogen or deuterium provided by an atomic beam source; and a symmetric, general purpose detector based on a toroidal spectrometer with tracking, time-of-flight, Cherenkov, and neutron detectors. Details of the experiment and operation are presented.

The thesis is based...... on ethnographic fieldwork among adults diagnosed with depression in Denmark, and consists of three articles that provide glimpses into experiences of depression and diagnostic processes. The articles deal with creativity, variability and resistance in diagnostic processes and illustrates how these not are once......-and-for-all-dealt-with matters but rather messy and complicated processes, that involve several actors and multiple relations to the diagnosis. The thesis furthermore challenges the dominant diagnostic understanding depression as a neurobiological, and individual disorder in present-day diagnostic cultures, by arguing...

      2010-01-01

      As part of the Institute for Creative Technologies and the School of Cinematic Arts at the University of Southern California, the Mixed Reality lab develops technologies and techniques for presenting realistic immersive training experiences. Such experiences typically place users within a complex ecology of social actors, physical objects, and collections of intents, motivations, relationships, and other psychological constructs. Currently, it remains infeasible to completely synthesize the interactivity and sensory signatures of such ecologies. For this reason, the lab advocates mixed reality methods for training and conducts experiments exploring such methods. Currently, the lab focuses on understanding and exploiting the elasticity of human perception with respect to representational differences between real and virtual environments. This paper presents an overview of three projects: techniques for redirected walking, displays for the representation of virtual humans, and audio processing to increase stress.

According to Jørgensen, Vattimo’s work as a philosopher is an example of ‘world-engaged philosophy’ as distinct...... from ‘school philosophy’ or ‘applied philosophy.’ The concept of ‘world-engaged philosophy’ is associated with Jørgensen’s concept of ‘world poetry’: that the immanent world is ambiguous; it occasions experiences of a surplus of meaning, traditionally called beauty. Furthermore, both concepts...... are associated with her concept of ‘basic experience’ and with her understanding of it as characterized by an immanent ‘dialogue’ between sensation, faith, and comprehension. According to Jørgensen, all experiences are rooted in sensation, faith, and comprehension; art, religion, and thought, or aesthetics...

      2001-01-01

      We discuss the relative use of neutrons and X-rays as scattering tools to probe the magnetic properties of materials. Neutron diffraction experiments continue to be the most appropriate tool to determine the magnetic structure of bulk solids. Synchrotron X-ray experiments are and will be used to investigate selectively the magnetic behaviour of different chemical species and/or electronic shells in magnetic systems. There exist some grey areas where the two probes can be used depending on the scientific problem under investigation. In particular, neutrons allow very accurate measurements of magnetic form factors, but X-rays provide a separation of the orbital momentum contribution to magnetisation. Comparisons between X-rays and neutrons studies of magnetism at surfaces are presented. Finally, one can anticipate that only inelastic neutron scattering experiments will allow the observation of magnetic excitations across the whole Brillouin zone

      Slovenian Nuclear Safety Administration (SNSA) has developed its own system for tracking, screening and evaluating the operating experiences of the nuclear installations. The SNSA staff regularly tracks the operating experiences throughout the world and screens them on the bases of applicability for the Slovenian nuclear facilities. The operating experiences, which pass the screening, are thoroughly evaluated and also recent operational events in these facilities are taken into account. If needed, more information is gathered to evaluate the conditions of the Slovenian facilities and appropriate corrective actions are considered. The result might be the identification of the need for modification at the licensee, the need for modification of internal procedures in the SNSA or even the proposal for the modification of regulations.

    13. Experience Innovation in Tourism

      DEFF Research Database (Denmark)

      Jensen, Jens Friis; Sørensen, Flemming

      2017-01-01

      This paper discusses how front-line employees can play an important role in innovation processes that lead tourism companies from service production to experience creation. The increasing focus on experiential value by customers in general (Sundbo and Sørensen, 2013) puts pressure on service...... and typically do not consider front-line employees to be important innovation agents (Sørensen and Jensen, 2012). However, in this paper, an analysis of an experiment in Tivoli Gardens exemplifies the innovation and value creating potential of involving front-line employees in developing new practices...... companies to move from functional service production to creating experiences (Pine and Gilmore, 2013). This is also the case in tourism companies. In tourism, most encounters between employees and tourists operate on a service logic (Sørensen and Jensen, 2015). Thus, we suggest there is a value potential...

      2016-01-01

      The Insertable B-Layer (IBL) is the inner most pixel layer in the ATLAS experiment, which was installed at 3.3 cm radius from the beam axis in 2014 to improve the tracking performance. To cope with the high radiation and hit occupancy due to proximity to the interaction point, a new read-out chip and two different silicon sensor technologies (planar and 3D) have been developed for the IBL. After the long shut-down period over 2013 and 2014, the ATLAS experiment started data-taking in May 2015 for Run-2 of the Large Hadron Collider (LHC). The IBL has been operated successfully since the beginning of Run-2 and shows excellent performance with the low dead module fraction, high data-taking efficiency and improved tracking capability. The experience and challenges in the operation of the IBL is described as well as its performance.

      In 1977, in a record-time of 9 months, the magnets of the g-2 experiment were modified and used to build a proton/antiproton storage ring: the "Initial Cooling Experiment" (ICE). It served for the verification of the cooling methods to be used for the "Antiproton Project". Stochastic cooling was proven the same year, electron cooling followed later. Also, with ICE the experimental lower limit for the antiproton lifetime was raised by 9 orders of magnitude: from 2 microseconds to 32 hours. For its previous life as g-2 storage ring, see 7405430.

      The oceans are an equal partner with the atmosphere in the global climate system. The World Ocean Circulation Experiment is presently being implemented to improve ocean models that are useful for climate prediction both by encouraging more model development but more importantly by providing quality data sets that can be used to force or to validate such models. WOCE is the first oceanographic experiment that plans to generate and to use multiparameter global ocean data sets. In order for WOCE to succeed, oceanographers must establish and learn to use more effective methods of assembling, quality controlling, manipulating and distributing oceanographic data.

    9. MELCOR 1.8.5 modeling aspects of fission product release, transport and deposition an assessment with recommendations.

      Energy Technology Data Exchange (ETDEWEB)

      Gauntt, Randall O.

      2010-04-01

      The Phebus and VERCORS data have played an important role in contemporary understanding and modeling of fission product release and transport from damaged light water reactor fuel. The data from these test programs have allowed improvement of MELCOR modeling of release and transport processes for both low enrichment uranium fuel as well as high burnup and mixed oxide (MOX) fuels. This paper discusses the synthesis of these findings in the MELCOR severe accident code. Based on recent assessments of MELCOR 1.8.5 fission product release modeling against the Phebus FPT-1 test and on observations from the ISP-46 exercise, modifications to the default MELCOR 1.8.5 release models are recommended. The assessments identified an alternative set of Booth diffusion parameters recommended by ORNL (ORNL-Booth), which produced significantly improved release predictions for cesium and other fission product groups. Some adjustments to the scaling factors in the ORNL-Booth model were made for selected fission product groups, including UO{sub 2}, Mo and Ru in order to obtain better comparisons with the FPT-1 data. The adjusted model, referred to as 'Modified ORNL-Booth,' was subsequently compared to original ORNL VI fission product release experiments and to more recently performed French VERCORS tests, and the comparisons was as favorable or better than the original CORSOR-M MELCOR default release model. These modified ORNL-Booth parameters, input to MELCOR 1.8.5 as 'sensitivity coefficients' (i.e. user input that over-rides the code defaults) are recommended for the interim period until improved release models can be implemented into MELCOR. For the case of ruthenium release in air-oxidizing conditions, some additional modifications to the Ru class vapor pressure are recommended based on estimates of the RuO{sub 2} vapor pressure over mildly hyperstoichiometric UO{sub 2}. The increased vapor pressure for this class significantly increases the net transport of Ru

      The OLYMPUS experiment was designed to measure the ratio between the positron–proton and electron–proton elastic scattering cross-sections, with the goal of determining the contribution of two-photon exchange to the elastic cross-section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, μ p G E p /G M p , made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25°–75°. Symmetric Møller/Bhabha calorimeters at 1.29° and telescopes of GEM and MWPC detectors at 12° served as luminosity monitors. A total luminosity of approximately 4.5 fb −1 was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment

      An experiment simulating the behavior of the very large steam bubbles generated at the time of an accident of core collapse was carried out with a warm water tank, and the applicability of the theory of very small bubble disappearance known at present was examined. The bubbles generated in HCDA (hypothetical core disruptive accident) are expected to be very large, containing sodium, fuel, FP gas and so on, and play important role in the mechanism of emitting radioactive substances in the safety analysis of LMFBRs. In this experiment, the degree of subcool of the warm water pool, the initial radii of steam bubbles and the blowoff pressure of steam were taken as the parameters. The radius of the steam bubbles generated in the experiment was about 6.5 cm, and the state of disappearance was different above and below the degree of unsaturation of 10 deg C. Comparing the disappearance curve obtained by the experiment with the theory of disappearance of small bubbles, the experimental values were between inertia-controlled disappearance and heat transfer-controlled disappearance, and this result was able to be explained generally with the model taking the pressure change within steam bubbles into account. The rise of bubbles was also observed. (Kako, I.)

    6. Prospects in coincidence experiments

      Laget, J.M.

      1984-01-01

      The sensitivity of virtual photons to the local variations of the charge and magnetization densities is exploited to study the short-range part of the nucleon-nucleon interaction inside the nucleus. The possibility of varying energy, squared mass and longitudinal polarization of the photons independently enables us to disentangle the mechanisms related to the internal structure of the nucleon (e.g. quark interchange) and the contribution due to meson exchange. Coincidence experiments of the type (e,e'N) and (e,e'NN) are performed to suppress the meson contribution to the longitudinal part of the quasi-elastic peak. Four typical examples of coincidence experiments induced by virtual photons are discussed: experiments (1) on the spectroscopic structure of the quasi-elastic peak and the problem of deep lying hole states; (2) on the structure of the continuum; (3) on the low energy side of the quasi-elastic peak; and finally a three-arm coincidence experiment.

      Whipply's icy conglomerate model of the comet nucleus has enjoyed progressively increasing acceptance and success in explaining Earth-based observations of comets since its very inception (Whipple, 1950, 1951). According to this model, the nucleus is a solid body composed of frozen gases and dust. The missions to Comet Halley in 1986, in particular the Vega and the Giotto missions, have confirmed that there is a single solid nucleus that is the root of all the observed phenomena that can be associated with an active comet. Two new comet mission (CRAF and Rosetta) are planned by NASA and ESA to extract further details about the structure and composition of the nucleus. Laboratory experiments play an important role in defining and identifying the objectives of these missions. Although such experiments have been carried out in many laboratories in Europe, the Soviet Union, the USA, Israel, and Japan, the KOSI experiments are the first large-scale investigations (in spatial dimensions and duration). (KOSI is an acronym for Kometensimulation, German for comet simulation). Starting with a summary and explanation of the KOSI experiments by Grun et al. (1991) and some of the experimental limitations by Keller and Markiewicz (1991), the author reports in this special issue the progress achieved about halfway through the planned series of investigations

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

This paper summarises the project and the experiences gained from it.

    12. [The AMY experiment

      International Nuclear Information System (INIS)

      1989-01-01

      The AMY experiment is one of three major experiments at TRISTAN which is studying the states the matter produced in electron positron annihilations in the center of mass energy range of 50--65GeV. It provides information between the lower energy facilities such as PEP and PETRA and the new facilities SLC and LEP which are designed to operate in the region of the Z 0 mass near 90GeV. In the region of the AMY experiment, interaction cross sections are near their minimum of about 100pb, making it difficult to acquire large data samples during typical running cycles. This last year has seen an accumulation of about 10---12pb -1 of integrated luminosity in the energy range from 58 to 61.7GeV. Despite this limited data sample, the AMY experiment has been extremely active in attempting to extract the minimum amount of information from the data. Some of the most significant results are discussed in this paper. 9 refs

      An electron wave function's phase distribution can now be precisely measured to 1/100th of the electron wavelength using both electron holography and a 'coherent' field-emission electron beam. This technique has opened up a new way to conduct thought experiments once regarded as experimentally impossible and also allows the ultra-fine measurement of material structures and field distributions.

      The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

      This paper discusses the experience from the Olkiluoto 3 nuclear power plant project from regulator's point of view. There are certain factors that have affected greatly the project progress. First, Olkiluoto 3 nuclear power plant is the first European Pressurised Reactor (EPR) being constructed. Secondly, construction of the unit started after a fairly long break in nuclear power plant construction in Europe, which had resulted in loss of experienced and qualified engineering and manufacturing resources. These factors have to be kept in mind when evaluating the experience from Olkiluoto 3. Experience discussed in this paper have to do with the licensing and regulatory oversight process, completion of the design prior to construction, experience and know-how of the participating organisations, quality management in a nuclear construction project, advanced manufacturing and construction technologies, turnkey contract with regard to licensee's responsibility, safety culture aspects in a nuclear construction project, and the role and importance of regulator's oversight.

      Full Text Available Although there have been studies that focus on the experiences of the gay and lesbian population serving in the United States military, few have focused on the experience of active duty transgender service members. Transgender individuals transgress the binary conception of gender by deviating from societal gender norms associated with assigned sex at birth. The Department of Defense has set policies and standards that reflect a binary conception of gender, with a focus on conformity. We argue that able-bodied gender variant service personnel are just as capable of serving their country as anyone else. Because of the repercussions associated with active duty transgender military personnel, our sample is small and involves nine clandestine service members and two international service members who wanted to share their stories from a different perspective. Snowball sampling was aimed at finding current active duty and reserve transgender service members. Using a combination of telephone interviews and questionnaires, data were collected from active duty transgender service personnel throughout the United States and two from international militaries that allow transgender people to serve. Data collection focused on the overall experiences of the participants along with questions regarding workplace discrimination, suggestions for policy changes, and their views about the overturn of Don’t Ask, Don’t Tell. Our findings add to a growing source of information about the transgender military experience in the U.S. armed forces and the importance of overturning discriminatory workplace policies that negatively impact transgender service members.

      This is a major subject since the aim is to grant human beings physical, mental, social and spiritual well-being without forgetting the sacred rights of all animals. Most international codes dealing with health-related research practices state that research developed in human beings should be based on previous lab animal experiments or on other scientific data. This article aimed at explaining ethics in animal experiments. The concepts of dissertation and thesis, experimental thesis, experimental essay or pilot experiment and experimental animal facilities are reviewed. Then, a historical retrospective is drawn about the first attempt to develop experimental research policies during the mid 19th Century, in London. It is highlighted that some criteria defined by that time still persist. The first animal research ethical committee was created in Sweden in 1979, followed by the USA in1984. In Brazil, animal research ethical committees were created as late as in the 90s. The Federal Law 6638 was passed in May 1979 and provides for the didactic-scientific practice of animal vivisection. This law, however, is still waiting for regulation. In addition, there are some drafts being analyzed by the Congress, which provide for the use of animals for teaching and research purposes. Finally, the policies adopted by the Brazilian College of Animal Experiments and the Universal Declaration of Animal Rights are presented. Professors, postgraduates, residents and graduate students of a Medical School involved in animal research should be aware of the ethical principles aiming at protecting animals selected for scientific work.

    1. The Mobilisatsia experience

      De Boever, P.

      2005-01-01

      The hazards of long-duration manned space flight are real. In order to participate effectively in long duration orbital missions or to continue the exploration of space, the health of the astronaut must be secured. There is mounting evidence that changes in the immune response of an astronaut in short-term flights, resemble those occurring after acute stress, while the changes during long-term flights resemble those caused by chronic stress. This blunting of the immune system occurs concomitant with a relative increase in microbial contamination in the space cabin environment. Such a combination of events results in an increased probability of in-flight infectious events. Micro-organisms are subject to a genetic evolution, which may lead to the capacity to colonize new environments and to cause infections. Central players in this evolutionary process are mobile genetic elements. They help to mobilize and reorganize genes, be it within a given genome (intragenomic mobility) or between bacterial cells (intercellular mobility). Hence, the processes of genetic exchange can mobilize genetic elements between bacterial strains, and therefore play a role in determining the infectious potential. The specific confined environment and space-flight related factors (such as microgravity and cosmic radiation) may increase the frequency in which mobile genetic elements are exchanged between micro organisms. The aim of the Mobilisatsia experiment was to promote microbial gene transfer under space flight conditions during a short-term experiment conducted aboard the International Space Station (ISS). The efficiency of the gene exchange process was compared with a synchronously performed ground control experiment. An experiment was carried out with well-characterized Gram-negative reference strains and one experiment was done with Gram-positive reference strains

      2013-06-01

      In this paper the author approaches mental pain and the problems in a psychoanalytic treatment of patients with difficulties in the psychic transformation of their emotional experiences. The author is interested in the symbolic failure related to the obstruction of development of phantasies, dreams, dream-thoughts, etc. She differentiates symbolization disturbances related to hypertrophic projective identification from a detention of these primitive communications and emotional isolation. She puts forward the conjecture that one factor in the arrest of this development is the detention of projective identifications and that, when this primitive means of communication is re-established in a container-contained relationship of mutual benefit, this initiates the development of a symbolization process that can replace the pathological 'protection'. Another hypothesis she develops is that of inaccessible caesuras that, associated with the detention of projective identification, obstruct any integrative or interactive movement. This caesura and the detention of projective identifications affect mental functions needed for dealing with mental pain. The personality is left with precarious mental equipment for transforming emotional experiences. How can a psychoanalytical process stimulate the development of creative symbolization, transforming the emotional experiences and leading towards mental growth? The author approaches the clinical problem with the metaphor of the psychic birth of emotional experience. The modulation of mental pain in a container-contained relationship is a central problem for the development of the human mind. For discovering and giving a meaning to emotional experience, the infant depends on reverie, a function necessary in order to develop an evolved consciousness capable of being aware, which is different from the rudimentary consciousness that perceives but does not understand. The development of mature mental equipment is associated with the

    4. LCLS The First Experiments

      Energy Technology Data Exchange (ETDEWEB)

      Galayda, John N

      2003-02-10

      The Scientific Advisory Committee (SAC) for the Linac Coherent Light Source (LCLS) has selected six scientific experiments for the early phase of the project. The LCLS, with proposed construction in the 2003-2006 time frame, has been designed to utilize the last third of the existing Stanford Linear Accelerator Center (SLAC) linac. The linac produces a high-current 5-15 GeV electron beam that is bunched into 230 fs slices with a 120 Hz repetition rate. When traveling through a sufficiently long (of order of 100 m) undulator, the electron bunches will lead to self amplification of the emitted x-ray intensity constituting an x-ray free electron laser (XFEL). If funded as proposed, the LCLS will be the first XFEL in the world, operating in the 800-8,000 eV energy range. The emitted coherent x-rays will have unprecedented brightness with 10{sup 12}-10{sup 13} photons/pulse in a 0.2-0.4% energy bandpass and an unprecedented time structure with a design pulse length of 230 fs. Studies are under way to reduce the pulse length to tens of femtoseconds. This document presents descriptions of the early scientific experiments selected by SAC in the spring of 2000. They cover a wide range of scientific fields. The experimental teams consist of many internationally recognized scientists who are excited about the unprecedented x-ray capabilities of LCLS that surely will lead to new scientific frontiers. More generally, this document serves to forward the scientific case for an accelerator-based XFEL source, as requested by the BESAC subpanel on Novel Coherent Light Sources, chaired by Stephen R. Leone. Two general classes of experiments are proposed for the LCLS. The first class consists of experiments where the x-ray beam is used to probe the sample without modifying it, as is done in most experiments at current synchrotron sources. In the second class, the LCLS beam is used to induce non-linear photo-processes or matter in extreme conditions. The same source can be used for

      1998-04-01

      What questions come about as learners explore physical materials? How does their learning deepen through inventing experiments and making and testing their own interpretations? I present episodes from the investigatory work of three adult learners who met regularly with me to explore batteries, bulbs and wires. I taught by engaging the learners' interest in these materials and by interactively researching their developing understandings. As both teacher and researcher, I used what I learned about their understandings to support their efforts to extend the body of experimental knowledge they were developing. Development is evident in experimental details. Initially, by hand-holding, they light a bulb with a wire and battery. Later, in soldering connections, they wonder about the bulb's internal structure. They research thoughts about this through dissecting a bulb -- and lighting its exposed filament. Such experimenting changed thinking: from imagining sequential loops, to questioning electrical contacts, to inferring circuital paths.

      Full Text Available The thermal-relic mechanism for the production of dark-matter in the early universe, combined with the precision measurements of the cosmic microwave background and the lack of observation of dark matter at the LHC, motivates the search for dark matter in the mass range between 1 MeV and 1 GeV. We describe the concept for the Light Dark Matter Experiment (LDMX, which could carry out such a search using the missing-momentum technique. The experiment would utilize a unique high-rate, low-current electron beam with an energy between 4 GeV and 10 GeV, and would have sensitivity to the thermal-relic hypothesis over a wide range of masses below 1 GeV.

Topics in charm and kaon physics, in which the measurements of ACP and the branching ratios of the rare decays K→πνν¯ are key measurements, will be discussed. Finally the complementarity of the future heavy flavour experiments, the LHCb upgrade and Belle‐II, will be summarised. PMID:26877543

      The CMS experiment is getting ready to take data at the LHC accelerator at CERN. Due to late delivery of the experimental caverns the detector had to be pre-assembled on the surface and lowered in large segments. This has constrained the commissioning strategy of the experiment. Global commissioning has started in Spring of 2007 and has progressed in parallel with the construction and assembly of detector and services underground. This paper describes the strategy adopted in order to commission components of the system in incremental steps in order to be ready to accept collisions from LHC with a well debugged and understood system, including the detector, acquisition system, trigger, software, computing and data shipping.

    11. Digital Heritage Experiences

      The evolution of the Web and the expansion of social media are transforming our heritage experiences. Social media offer an innovative element to personal travel reflections by providing digital global platforms on which tourists can create and publish their travel stories. Social media transform...... the traditional creative processes, distribution mechanisms and consumption patterns of these experiences. This study provides insight on how personal heritage moments are constructed, digitalized and shared. The methodological perspective adopted draws on a constructivist epistemology (Markham 2004......) and netnography (Kozinets, 2002). The social media platform analysed is TripAdvisor, which is the largest networking site focusing on tourism and travel. Study findings indicate that while heritage sites tend to promote their uniqueness and the cultural value of their products, tourists are just as concerned...

    12. New Experiments with Antiprotons

      Kaplan, D. M.

      2011-12-01

      Fermilab operates the world's most intense antiproton source. Recently proposed experiments can use those antiprotons either parasitically during Teva-tron Collider running or after the Tevatron Collider finishes in about 2011. For example, the annihilation of 8 GeV antiprotons might make the world's most intense source of tagged D0 mesons, and thus the best near-term opportunity to study charm mixing and search for new physics via its CP-violation signature. Other possible precision measurements include properties of the X(3872) and the charmonium system. An experiment using a Penning trap and an atom interferometer could make the world's first measurement of the gravitational force on antimatter. These and other potential measurements using antiprotons could yield a broad physics program at Fermilab in the post-Tevatron era.

      Muon experimental facility is in the planning stage as a part of the high intensity proton accelerator project of KEK and JAERI. Outline of muon experimental facility and physical experiments are described. There are five kinds of beam channels such as superconducting solenoid, surface muon, ultra-slow muon, high momentum muon and ultra-high intensity muon. The μSR method by positive electric charge muon makes possible to study antiferromagnet, spin glass, muon spin high-frequency resonance and paramagnetic shift. The positive electric charge muon is one of hydrogen isotopes. Accordingly, the quantum diffusion experiments of metals, semiconductor and insulator are carried out by the isotope effect. Development of muon catalyzed fusion by negative electric charge muon is one of problems of this facility. It can be applied to chemical reaction and non-destructive analysis. An illustration of the history of muon science is shown. (S.Y.)

      Full Text Available A new quantum gravity experiment is reported with the data confirming the generali- sation of the Schrödinger equation to include the interaction of the wave function with dynamical space. Dynamical space turbulence, via this interaction process, raises and lowers the energy of the electron wave function, which is detected by observing conse- quent variations in the electron quantum barrier tunnelling rate in reverse-biased Zener diodes. This process has previously been reported and enabled the measurement of the speed of the dynamical space flow, which is consistent with numerous other detection experiments. The interaction process is dependent on the angle between the dynamical space flow velocity and the direction of the electron flow in the diode, and this depen- dence is experimentally demonstrated. This interaction process explains gravity as an emergent quantum process, so unifying quantum phenomena and gravity. Gravitational waves are easily detected.

      The Microwave Tokamak Experiment, now under construction at the Laboratory, will use microwave heating from a free-electron laser. The intense microwave pulses will be injected into the tokamak to realize several goals, including a demonstration of the effects of localized heat deposition within magnetically confined plasma, a better understanding of energy confinement in tokamaks, and use of the new free-electron laser technology for plasma heating. The experiment, soon to be operational, provides an opportunity to study dense plasmas heated by powers unprecedented in the electron-cyclotron frequency range required by the especially high magnetic fields used with the MTX and needed for reactors. 1 references, 5 figures, 3 tables

      In the wake of present European interest for mapping urban noise, it seems increasingly relevant to investigate the multiple ways in which sound intersects with the everyday experiences of urban citizens. Focusing on the polluting effects of infrastructural noise, the EU-initiated project...... of assessment and management of environmental noise brings forth the disturbing and potentially damaging effect of environmental sound.1 But as maps of coloured streets start to circulate, and real estate prices drop in designated blue and red areas,2 it is worth remembering that sound itself is not a killer....... Most of the time sound is a trivial part of everyday life involved in interactions, experiences, atmospheres, actions, etc. Although trivial, the role of the aural in the urban life world is more complex than what is suggested by sound level maps, and as such it may be a vital part of urbanity itself...

      The MOZART experiment was carried out within the framework of the BEATRIX program, as part of the Commissariat a l'Energie Atomique contribution to this international collaboration program. This experiment was run during 45 days in the MELUSIN reactor at Grenoble. Tested ceramics were Li 2 O and LiAlO 2 from Japan, Li 2 ZrO 3 from USA, LiAlO 2 from CEA. Influence of parameters such as temperature, sweep gas composition was investigated. Tritium residence times as a function of temperature were calculated. The comparison of the tritium release performance of the three ceramic breeders was made. This investigation has first evidenced the very good tritium release characteristics of Li 2 ZrO 3 especially at low temperatures. (author). 7 refs.; 5 figs.; 3 tabs

    1. The Vinca dosimetry experiment

      International Nuclear Information System (INIS)

      1962-03-01

      On 15 October 1958 there occurred a very brief uncontrolled run of the zero-power reactor at the Boris Kidric Institute of Nuclear Science, Vinca, near Belgrade, Yugoslavia. During this run six persons received various doses of radiation. They were subsequently given medical treatment of a novel kind at the Curie Hospital, Paris. In atomic energy operations to date, very few accidents involving excessive radiation exposure to human beings have occurred. In fact, the cases of acute radiation injury are limited to about 30 known high exposures, few of which were in the lethal or near-lethal range. Since direct experiment to determine the effects of ionizing radiation on man is unacceptable, information on these effects has to be based on a consideration of data relating to accidental exposures, viewed in the light of the much more extensive data obtained from experiments on animals. Therefore, any direct information on the effects of radiation on humans is very valuable. The international dosimetry project described in this report was carried out at Vinca, Yugoslavia, under the auspices of the International Atomic Energy Agency to determine the precise amount of radiation to which the persons had been exposed during the accident. These dosimetry data, together with the record of the carefully observed clinical effects, are of importance both for the scientific study of radiation effects on man and for the development of methods of therapy. The experiment and measurements were carried out at the end of April 1960. The project formed part of the Agency's research programme in the field of health and safety. The results of the experiment are made available through this report to all Member States

In today's marketplace, occupational health nurses understand that differentiation (i.e., the perception of uniqueness) is the direct result of superior employee interactions, which lead to better employee care, enduring employee relationships, loyal employees, and satisfied employers. What drives employees to occupational health nurse attachment? The answer is a passion for rising above the competition to create ideal employee experiences.

ACE is located on the Antiproton Decelerator (AD) at CERN. An antiproton annihilates a proton in the nucleus of a cancer cell, producing a pair of gamma rays, destroying the entire cell and some surrounding cells. Many fewer antiprotons are required in this treatment than in the equivalent proton hadron therapy, so there is less risk of healthy tissue damage.

      Many natural phenomena can only be properly understood if one has a detailed knowledge of interactions involving atoms, molecules, ions, electrons or photons. In the laboratory these processes are often studied by preparing beams of two types of particle and observing the reactions which occur when the beams intersect. Some of the more interesting of these crossed beam experiments and their results are discussed. Proposals to extend colliding beam techniques to high energy particle physics are also outlined.

      1996-04-01

      Originating out of a SDIO-funded, Phase 1 study effort, two ground systems and an orbiting EO payload/spacecraft were the primary equipment for the RME. The RME was originally conceived to be a shuttle deployed experiment. Shortly after program start, the Challenger disaster occurred, with the promise of extensive delays. A completely new space segment was to be designed incorporating a free-flying spacecraft. During the midphase of the program, a variety of launch vehicles were envisioned to replace the shuttle, requiring the BASD team to design accommodations for Delta, Atlas, and Titan, with a Delta launch being the final solution. The ground systems tracked the spacecraft and illuminated it with green and blue beacon lasers. The Payload Experiment Package (PEP) housed the bisection tracker, a key innovation central to the experiment. The bisection tracker acquired both beacons and controlled steerable mirrors to accomplish fine tracking of the two cooperative beacons. In the process, the relay mirror was precisely positioned to enable a successful relay of a third infrared laser between the two ground sites via the orbiting spacecraft. Many of the key technologies employed in the PEP were originally developed for Ball laser communications research and development programs and other laser pointing efforts. The WAVE sensor package, built by ATA and integrated by Ball, measured the vibrations of the optical base structure on which it was mounted. These spacecraft vibration data are critical to the accurate pointing of space laser communication terminals.

      A sequential design of experiments strategy is being developed and implemented that allows for adaptive learning based on incoming results as the experiment is being run. The plan is to incorporate these strategies for the NCCC and TCM experimental campaigns to be run in the coming months. This strategy for experimentation has the advantages of allowing new data collected during the experiment to inform future experimental runs based on their projected utility for a particular goal. For example, the current effort for the MEA capture system at NCCC plans to focus on maximally improving the quality of prediction of CO2 capture efficiency as measured by the width of the confidence interval for the underlying response surface that is modeled as a function of 1) Flue Gas Flowrate [1000-3000] kg/hr; 2) CO2 weight fraction [0.125-0.175]; 3) Lean solvent loading [0.1-0.3], and; 4) Lean solvent flowrate [3000-12000] kg/hr.

      Shock driven multiphase instabilities (SDMI) are unique physical phenomena that have far-reaching practical applications in engineering and science. The instability is present in high energy explosions, scramjet combustors, and supernovae events. The SDMI arises when a multiphase interface is impulsively accelerated by the passage of a shockwave. It is similar in development to the Richtmyer-Meshkov (RM) instability however, particle-to-gas coupling is the driving mechanism of the SDMI. As particle effects such as lag and phase change become more prominent, the SDMI's development begins to significantly deviate from the RM instability. We have developed an experiment for studying the SDMI in our shock tube facility. In our experiments, a multiphase interface is created using a laminar jet and flowed into the shock tube where it is accelerated by the passage of a planar shockwave. The interface development is captured using CCD cameras synchronized with planar laser illumination. This talk will give an overview of new experiments conducted to examine the development of a shocked cylindrical multiphase interface. The effects of Atwood number, particle size, and a second acceleration (reshock) of the interface will be discussed.

Although there is a growing interest on User Experience, there are still limited resources (i.e. measurement tools or questionnaires available to measure user experience of any products, especially learning management systems. Two hundreds and thirteen computer science students participated and completed the adapted version of UEQ. In the study, the researchers used a learning management system named Student Centered e-Learning Environment (SCELE. Several types of learning materials are posted in SCELE such as audio files, simulations, PowerPoint slides, multimedia contents, and webpage links. Most of the lecturers use discussion forums in their courses to encourage students to participate in active learning setting. Staff and lecturers sometimes post academic-related announcements on the SCELE homepage. Two hundred thirteen students enrolled in Computer Science program were invited to evaluate the SCELE. This study will benefit UX practitioners, HCI educators, program and center of learning resources administrators, and learning management system developers. Findings of the present study may also be valuable for universities and high schools which are using computer-based learning environments.

      The Tango control system framework allows you to control an accelerator complex as well as single equipment. The framework contains the communication bus with the standard communication modes (synchronous, asynchronous, event driven) as well as the basic hardware access modules, GUI tools and development kits, bindings to commercial products (LabView, Matlab, IgorPro) and services (administration, archiving, access control) to set up a control system. Tango was mainly developed by several synchrotron light sources that have to support not only the accelerator complex but also a lot of experimental end stations. For synchrotron experiments we have to control the whole process from basic hardware access over data taking to data analysis. This paper describes in the first part the special features of Tango allowing flexible experiment control. The dynamic configuration, the rapid hardware interface development and the sequencing and scanning framework are some examples. The second part gives an overview of some packages developed in the Tango community for experiment control: A HKL library for diffraction computation and diffractometer control, a library to control 2D detectors and a data analysis workbench with workflow engine for on-line and off-line data analysis. These packages are not part of Tango and can be used with other control systems. (author)

      1995-01-01

      Full text: A major effort is being mounted to prepare the way handling the high interaction rates expected from CERN's new LHC proton-proton collider (see, for example, November, page 6). September saw the First Workshop on Electronics for LHC Experiments, organized by Lisbon's Particle Physics Instrumentation Laboratory (LIP) on behalf of CERN's LHC Electronics Review Board (LERB - March, page 2). Its purpose was not only for the LERB to have a thorough review of ongoing activities, but also to promote cross fertilization in the engineering community involved in electronics design for LHC experiments. The Workshop gathered 187 physicists and engineers from 20 countries including USA and Japan. The meeting comprised six sessions and 82 talks, with special focus on radiation-hard microelectronic processes, electronics for tracking, calorimetry and muon detectors, optoelectronics, trigger and data acquisition systems. Each topic was introduced by an invited speaker who reviewed the requirements set by the particular detector technology at LHC. At the end of each session, panel discussions were chaired by each invited speaker. Representatives from four major integrated circuit manufacturers covered advanced radiation hard processes. Two talks highlighted the importance of obsolescence and quality systems in the long-lived and demanding environment of LHC. The Workshop identified areas and encouraged efforts for rationalization and common developments within and between the different detector groups. As a result, it will also help ensure the reliability and the long term maintainability of installed equipment. The proceedings of the Workshop are available from LIP Lisbon*. The LERB Workshop on Electronics for LHC Experiments will become a regular event, with the second taking place in Hungary, by Lake Balaton, from 23-27 September 1996. The Hungarian institutes KFKIRMKI have taken up the challenge of being as successful as LIP Lisbon in the organization

      2011-10-01

      The Moon is, together with the Sun, the very first astronomical object that we experience in our life. As this is an exclusively visual experience, people with visual impairments need a different mode to experience it too. This statement is especially true when events, such as more and more frequent public observations of sky, take place. This is the reason why we are preparing a special package for visual impaired people containing three brand new items: 1. a tactile 3D Moon sphere in Braille with its paper key in Braille. To produce it we used imaging data obtained by NASA's mission Clementine, along with free image processing and 3D rendering software. In order to build the 3D small scale model funding by Europlanet and the Italian Ministry for Research have been used. 2. a multilingual web site for visually impaired users of all ages, on basic astronomy together with an indepth box about the Moon; 3. a book in Braille with the same content of the Web site mentioned above. All the items will be developed with the collaboration of visually impaired people that will check each step of the project and support their comments and criticism to improve it. We are going to test this package during the next International Observe the Moon Night event. After a first testing phase we'll collect all the feedback data in order to give an effective form to the package. Finally the Moon package could be delivered to all those who will demand it for outreach or educational goals.

    12. 2169 steel waveform experiments.

      2012-11-01

      In support of LLNL efforts to develop multiscale models of a variety of materials, we have performed a set of eight gas gun impact experiments on 2169 steel (21% Cr, 6% Ni, 9% Mn, balance predominantly Fe). These experiments provided carefully controlled shock, reshock and release velocimetry data, with initial shock stresses ranging from 10 to 50 GPa (particle velocities from 0.25 to 1.05 km/s). Both windowed and free-surface measurements were included in this experiment set to increase the utility of the data set, as were samples ranging in thickness from 1 to 5 mm. Target physical phenomena included the elastic/plastic transition (Hugoniot elastic limit), the Hugoniot, any phase transition phenomena, and the release path (windowed and free-surface). The Hugoniot was found to be nearly linear, with no indications of the Fe phase transition. Releases were non-hysteretic, and relatively consistent between 3- and 5-mmthick samples (the 3 mm samples giving slightly lower wavespeeds on release). Reshock tests with explosively welded impactors produced clean results; those with glue bonds showed transient releases prior to the arrival of the reshock, reducing their usefulness for deriving strength information. The free-surface samples, which were steps on a single piece of steel, showed lower wavespeeds for thin (1 mm) samples than for thicker (2 or 4 mm) samples. A configuration used for the last three shots allows release information to be determined from these free surface samples. The sample strength appears to increase with stress from ~1 GPa to ~ 3 GPa over this range, consistent with other recent work but about 40% above the Steinberg model.

    13. Southeast Regional Experiment Station

      1994-08-01

      This is the final report of the Southeast Regional Experiment Station project. The Florida Solar Energy Center (FSEC), a research institute of the University of Central Florida (UCF), has operated the Southeast Regional Experiment Station (SE RES) for the US Department of Energy (DOE) since September 1982. Sandia National Laboratories, Albuquerque (SNLA) provides technical program direction for both the SE RES and the Southwest Regional Experiment Station (SW RES) located at the Southwest Technology Development Institute at Las Cruces, New Mexico. This cooperative effort serves a critical role in the national photovoltaic program by conducting system evaluations, design assistance and technology transfer to enhance the cost-effective utilization and development of photovoltaic technology. Initially, the research focus of the SE RES program centered on utility-connected PV systems and associated issues. In 1987, the SE RES began evaluating amorphous silicon (a-Si) thin-film PV modules for application in utility-interactive systems. Stand-alone PV systems began receiving increased emphasis at the SE RES in 1986. Research projects were initiated that involved evaluation of vaccine refrigeration, water pumping and other stand-alone power systems. The results of this work have led to design optimization techniques and procedures for the sizing and modeling of PV water pumping systems. Later recent research at the SE RES included test and evaluation of batteries and charge controllers for stand-alone PV system applications. The SE RES project provided the foundation on which FSEC achieved national recognition for its expertise in PV systems research and related technology transfer programs. These synergistic products of the SE RES illustrate the high visibility and contributions the FSEC PV program offers to the DOE.

      Operating Experience (OE) provides valuable information for improving NPP safety. This may include events, precursors, deviations, deficiencies, problems, new insights to safety, good practices, lessons and corrective actions. As per INSAG-10, an OE program caters as a fundamental means for enhancing the defence-in-depth at NPPs and hence should be viewed as ‘Continuous Safety Performance Improvement Tool’. The ‘Convention on Nuclear Safety’ also recognizes the OE as a tool of high importance for enhancing the NPP safety and its Article 19 mandates each contracting party to establish an effective OE program at operating NPPs. The lessons drawn from major accidents at Three Mile Island, Chernobyl and Fukushima Daiichi NPPs had prompted nuclear stalwarts to change their safety perspective towards NPPs and to frame sound policies on issues like safety culture, severe accident prevention and mitigation. An effective OE program, besides correcting current/potential problems, help in proactively improving the NPP design, operating and maintenance procedures, practices, training, etc., and thus plays vital role in ensuring safe and efficient operation of NPPs. Further it enhances knowledge with regard to equipment operating characteristics, system performance trends and provides data for quantitative and qualitative safety analysis. Besides all above, an OE program inculcates a learning culture in the organisation and thus helps in continuously enhancing the expertise, technical competency and knowledge base of its staff. Nuclear and Radiation Facilities in India are regulated by Atomic Energy Regulatory Board (AERB). Operating Plants Safety Division (OPSD) of AERB is involved in managing operating experience activities. This paper provides insights about the operating experience program of OPSD, AERB (including its on-line data base namely OPSD STAR) and its utilisation in improving the regulations and safety at Indian NPPs/projects.

    16. Supersymmetry shaken by experiment

      International Nuclear Information System (INIS)

      Glavieux, Vincent

      2012-01-01

      The author comments how experiments performed within the CERN large hadron collider (LHC) may bring answers to the issue of the existence of supersymmetrical particles, i.e. the fact that a super-particle would be associated with each particle according to the ideas of Pierre Fayet, and more particularly the relationship between fermions and bosons. The theoretical background is presented as well as the different tested models: the GMSB (gauge mediated supersymmetry breaking) and the mSugra (minimal supergravity) models. Since 2009, if researchers actually identified all known particles, they could not find any trace of superparticles. This may put the models into question again

      1998-01-01

      A series of ballooning experiments was performed at the KFKI-AEKI in order to compare the mechanical behaviour and strength of Zircaloy-4 and Zr1%Nb claddings. The effects of temperature, oxidation and iodine absorption on deformation and burst pressure was investigated in almost 100 biaxial tests. Numerical post-test analyses have also been performed with the stand-alone fuel module of the French CATHARE code and the US fuel behaviour code FRAP-T6. Comparing the experimental and the analytical results, relevant differences of high temperature strength due to different α-β phase transition temperature were revealed between the investigated cladding materials.

      International Nuclear Information System (INIS)

      Lacy, C.S.; Patterson, R.W.; Upton, M.S.

      1991-01-01

      Ontario Hydro currently operates 18 nuclear electric generating units of the CANDU design with a net capacity of 12,402 MW(e). An additional 1,762 MW(e) is under construction. The operation of these facilities has underlined the need to have decontamination capability both to reduce radiation fields, as well as to control and reduce contamination during component maintenance. This paper presents Ontario Hydro decontamination experience in two key areas - full heat transport decontamination to reduce system radiation fields, and component decontamination to reduce loose contamination particularly as practised in maintenance and decontamination centres.

      OPERA is a neutrino oscillation experiment designed to perform a ν τ appearance search in the future CNGS beam from CERN to Gran Sasso. The identification of the τ lepton produced by a CC ν τ interaction is based on the use of the nuclear emulsion technique. The OPERA detector is presently under construction in the Gran Sasso underground laboratory, 730 km from CERN, and will receive its first neutrinos in 2006. The experimental technique is reviewed and the development of the project described. Foreseen performances in measuring ν τ appearance and also in searching for ν e appearance are discussed

      The present status of experimental solar neutrino research is reviewed. Updated results from the Homestake, Kamiokande, GALLEX and SAGE detectors all show a deficit when compared to recent standard solar model calculations. Two of these detectors, GALLEX and SAGE, have recently been checked with artificial {sup 51}Cr neutrino sources. It is shown that astrophysical scenarios to solve the solar neutrino problems are not favoured by the data. There is hope that the results of forthcoming solar neutrino experiments can provide the answers to the open questions. (author) 6 figs., 3 tabs., 36 refs.

      Full Text Available The proton radius puzzle is the difference between the proton radius as measured with electron scattering and in the excitation spectrum of atomic hydrogen, and that measured with muonic hydrogen spectroscopy. The MUSE experiment seeks to resolve this puzzle by simultaneously measuring elastic electron and muon scattering on the proton, in both charge states, thereby providing new information to the puzzle. MUSE addresses issues of two-photon effects, lepton universality and, possibly, new physics, while providing simultaneous form factor, and therefore radius, measurements with both muons and electrons.

    7. Magnetic monopole search experiments

      International Nuclear Information System (INIS)

      Stone, J.L.

      1986-01-01

      Experimental searches for the elusive magnetic monopole have extended over 50 years -- ever since Dirac showed that the existence of isolated magnetic charges could account for the observation of quantized electric charge. Early searches for Dirac's monopole were hampered since there was no indication of the expected monopole mass, velocity, or origin in the theory. Consequently, numerous experiments searched more or less blindly for relativistic low mass monopoles in the cosmic rays and in particle collisions at high energy accelerators. In this paper, the author reviews briefly the monopole properties which are relevant for their detection and summarize current experimental efforts using induction, ionization/excitation, and catalysis techniques

      A fundamental obstacle to routine space access is the specific energy limitations associated with chemical fuels. In the case of vertical take-off, the high thrust needed for vertical liftoff and acceleration to orbit translates into power levels in the 10 GW range. Furthermore, useful payload mass fractions are possible only if the exhaust particle energy (i.e., exhaust velocity) is much greater than that available with traditional chemical propulsion. The electronic binding energy released by the best chemical reactions (e.g., LOX/LH2 for example, is less than 2 eV per product molecule (approx. 1.8 eV per H2O molecule), which translates into particle velocities less than 5 km/s. Useful payload fractions, however, will require exhaust velocities exceeding 15 km/s (i.e., particle energies greater than 20 eV). As an added challenge, the envisioned hypothetical RLV (reusable launch vehicle) should accomplish these amazing performance feats while providing relatively low acceleration levels to orbit (2-3g maximum). From such fundamental considerations, it is painfully obvious that planned and current RLV solutions based on chemical fuels alone represent only a temporary solution and can only result in minor gains, at best. What is truly needed is a revolutionary approach that will dramatically reduce the amount of fuel and size of the launch vehicle. This implies the need for new compact high-power energy sources as well as advanced accelerator technologies for increasing engine exhaust velocity. Electromagnetic acceleration techniques are of immense interest since they can be used to circumvent the thermal limits associated with conventional propulsion systems. This paper describes the Magnetohydrodynamic Augmented Propulsion Experiment (MAPX) being undertaken at NASA Marshall Space Flight Center (MSFC). In this experiment, a 1-MW arc heater is being used as a feeder for a 1-MW magnetohydrodynamic (MHD) accelerator. The purpose of the experiment is to demonstrate

Jinping is located in China JinPing underground Laboratory (CJPL), identified by the thickest overburden, lowest reactor neutrino background, etc. For solar neutrinos, Jinping has the capacity to measure the oscillation transition phase from vacuum to matter, to discover the CNO cycle neutrino, and to address the solar metallicity problem. Jinping will be able to precisely measure geo-neutrinos with signal-to-background ratio of 8.2:1.0 in the energy range of 1.8 MeV to 3.3 MeV. The ratio of U/Th can be determined to 10%. We also expect a promising sensitivity for neutrinos from a Milky Way supernova, the diffuse supernova neutrino background, and dark matter annihilation. The first, small phase of the laboratory (CJPL I) is already in operation, hosting dark matter experiments. The second, large phase (CJPL II) is already under construction, with ≈ 100,000 m3 being excavated.

      EBEX is a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background radiation. The measurements would probe the inflationary epoch that took place shortly after the big bang and would significantly improve constraints on the values of several cosmological parameters. EBEX is unique in its broad frequency coverage and in its ability to provide critical information about the level of polarized Galactic foregrounds which will be necessary for all future CMB polarization experiments. EBEX consists of a 1.5 m Dragone-type telescope that provides a resolution of less than 8 arcminutes over four focal planes each of 4. diffraction limited field of view at frequencies up to 450 GHz. The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave plate. EBEX is currently in the design and construction phase, and first light is scheduled for 2008

      The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

      The Halogen Occultation Experiment (HALOE) uses solar occultation to measure vertical profiles of O3, HCl, HF, CH4, H2O, NO, NO2, aerosol extinction, and temperature versus pressure with an instantaneous vertical field of view of 1.6 km at the earth limb. Latitudinal coverage is from 80 deg S to 80 deg N over the course of 1 year and includes extensive observations of the Antarctic region during spring. The altitude range of the measurements extends from about 15 km to about 60-130 km, depending on channel. Experiment operations have been essentially flawless, and all performance criteria either meet or exceed specifications. Internal data consistency checks, comparisons with correlative measurements, and qualitative comparisons with 1985 atmospheric trace molecule spectroscopy (ATMOS) results are in good agreement. Examples of pressure versus latitude cross sections and a global orthographic projection for the September 21 to October 15, 1992, period show the utility of CH4, HF, and H2O as tracers, the occurrence of dehydration in the Antarctic lower stratosphere, the presence of the water vapor hygropause in the tropics, evidence of Antarctic air in the tropics, the influence of Hadley tropical upwelling, and the first global distribution of HCl, HF, and NO throughout the stratosphere. Nitric oxide measurements extend through the lower thermosphere.

    2. PAC Experiments at ISOLDE

      2002-01-01

      The study of hyperfine interactions offers the possibility to use radioactive nuclei as probes in matter. The @g-@g perturbated angular correlation (PAC) technique following implantation has found widespread application in this field. At ISOLDE we have been investigating electric field gradients at impurities in non-cubic metals in an ongoing series of experiments. \\\\ \\\\ The small number of probe atoms necessary for these measurements make them also ideally suited for studies of surface problems like diffusion, structure and dynamics. Cd on a molybdenum O110? surface will be studied as first system. For this purpose 10|1|0~atoms of |1|1|1|mCd will be evaporated onto the clean surface and the electric field gradient for isolated adatoms on terrace sites will be determined by PAC. The UHV system constructed for such experiments at ISOLDE is shown in the schematic drawing. It is coupled to the beam line through differential pumping stations and contains standard surface treatment and analysis equipment.

      Full Text Available Introduction: There is very little published literature about experience with osteoporosis treatment from our country. Materials and Methods: It is a retrospective analysis of first 50 patients enrolled in our clinic for osteoporosis. Postmenopausal women with T score of less than -2.5 or history suggestive fragility fracture with supportive bone mineral density (BMD were included. Patients having hypercalcemia, abnormal renal function, myeloma and on long-term steroids were also excluded. Results: Nearly 34% subjects were below the age of 60 years, 47% of subjects were between 60 and 70 years, whereas 18% were above 70 years. Nearly 6% had family history of osteoporosis s or history of osteoporotic fractures. Nearly 20% subjects had fracture prior to starting of any treatment. A total of 86% (40/46 had evidence of Vitamin D (VD deficiency. Nearly 80% of patients were treated with bisphosphonates, 12% were treated with injectable bisphosphonates, and 8% were treated with teriperatide. Nearly 16% patients had duration of more than 5 years of experience with bisphosphonates. Follow up BMD was available in 25 subjects. BMD had improved significantly in 68% of subjects. In 24% the BMD was stable (the change was less than least significant change (LSC. In 8% BMD had shown a significant decline while being on treatment. Conclusion: Postmenopausal osteoporosis occurs in relatively younger women in our country. Majority of them are VD deficient. Oral bisphosphonates is the most common used drug; it is fairly well tolerated and effective.

    4. An Experiment in Synchronicity

      Click here and insert your abstract text. Possible states theory generalizes about the process of change within a finite and discrete model of the universe. The possible states consist of all interactions between objects, including past, future and possible interactions. The theory posits a non-electromagnetic model of change in which change propagates without reference to space-time. The theory delivers verifiable predictions and is generally consistent with quantum theory. It offers the prospect of nonlocal connections between objects and change that is not constrained by conservation laws. The value of the concept as a basis for technology development depends upon the ability to manipulate the possible states, specifically to produce coherence in selected collections of states. An experiment is devised in which a coherent state path is created between the experimental components and loaded through interaction with non-coherent states. Discharge of coherence results in a burst of synchronistic events compatible with theoretical expectations. The experiment validates a specific control strategy and yields a large timewise anomaly. The results shed light on a potential sentient intelligence and upon the development of coherence in the possible states and enable a major advance in the control of change.

      Planning has started towards designing a new field campaign aimed at studying the behaviour of the boundary layer over complex terrain. Of specific interest is the formation of cold-pools in valleys during stable night-time conditions. The field campaign will run continuously until the end of the winter in 2009/10. The experiment will make use of a wide variety of ground-based sensors including turbulence towers, automatic weather stations, Doppler lidar, radiation sensors and soil temperature probes. We also hope to deploy an instrumented car and a tethered balloon facility for limited periods. Data from the field campaign will be used for a number of purposes. Firstly, to increase our understanding of how the valley cold pools form and why, for instance, some valleys offer a more favourable environment for their formation than others. Secondly, to investigate the formation and dissipation of fog in complex terrain. Thirdly, the data set will also be used to help validate and develop the Met Office Unified Model at high resolution. An area for the experiment has been identified in the Shropshire/Powis area of the UK where a network of valleys and low hills exist with a typical valley width of ~1.5km and hill top to valley floor heights of 75-200m. 0m.

      Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that stirling machines are capable of reliable and lengthy operating lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and are not expected to operate for lengthy periods of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered. The record in this paper is not complete, due to the reluctance of some organizations to release operational data and because several organizations were not contacted. The authors intend to repeat this assessment in three years, hoping for even greater participation.

      To commemorate the once-in-a-lifetime event of Arizona's hundredth birthday, the Centennial Commission and the Governor of Arizona envisioned a museum and companion website that would capture the state's history, celebrate its people, and embrace its future. Working with world-renowned museum designers, the state began to seek ideas from across Arizona to create plans for a journey of discovery through science and the humanities. The museum would introduce visitors to some of the people who nurtured the state through its early years and others who are innovating its tomorrows. Showcases would include the resources and experiences that shaped the state's history and are transforming its present day, highlighting the ingenuity that tamed the wild frontier and is envisioning Arizona's next frontiers through science and technology. The Arizona Experience (www.arizonaexperience.org) was initially intended to serve as the web presence for the physical museum, but as delays occurred with the physical museum, the site has quickly developed an identify of its own as an interactive, multimedia experience, reaching a wider audience with functions that would be difficult or expensive to produce in a museum. As leaders in scientific and technological innovation in the state, the Arizona Geological Survey was tasked with designing and creating the Arizona Experience site. The general themes remain the same; however, the site has added content and applications that are better suited to the online environment in order to create a rich, dynamic supplement to a physical museum experience. The website offers the features and displays of the future museum with the interactive nature and learning environment of the web. This provides an encyclopedic overview of the State of Arizona by subject matter experts in a manner that is free and open to the public and erases socio-economic, political, and physical boundaries. Over the Centennial Year of 2012 the site will release a new theme and

      Petascale High-Performance Computing (HPC) systems are among the largest systems in the world. Intrepid, one such system, is a 40,000 node, 556 teraflop Blue Gene/P system that has been deployed at Argonne National Laboratory. In this paper, we provide some background about the system and our administration experiences. In particular, due to the scale of the system, we have faced a variety of issues, some surprising to us, that are not common in the commodity world. We discuss our expectations, these issues, and approaches we have used to address them. HPC systems are a bellwether for computing systems at large, in multiple regards. HPC users are motivated by the need for absolute performance; this results in two important pushes. HPC users are frequently early adopters of new technologies and techniques. Successful technologies, like Infiniband, prove their value in HPC before gaining wider adoption. Unfortunately, this early adoption alone is not sufficient to achieve the levels of performance required by HPC users; parallelism must also be harnessed. Over the last 15 years, beowulf clustering has provided amazing accessibility to non-HPC-savvy and even non-technical audiences. During this time, substantial adoption of clustering has occurred in many market segments unrelated to computational science. A simple trend has emerged: the scale and performance of high-end HPC systems are uncommon at first, but become commonplace over the course of 3-5 years. For example, in early 2003, several systems on the Top500 list consisted of either 1024 nodes or 4096-8192 cores. In 2008, such systems are commonplace. The most recent generation of high-end HPC systems, so called petascale systems, are the culmination of years of research and development in research and academia. Three such systems have been deployed thus far. In addition to the 556 TF Intrepid system at Argonne National Laboratory, a 596 TF Blue Gene/L-based system has been deployed at Lawrence Livermore

      2012-01-01

      Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

      One of the purposes of the SQA effort at LLNL is to attempt to determine the 'goodness' of the research codes used for various scientific applications. Typically these are two and three dimensional multi-physics simulation and modeling codes. These legacy research codes are used for applciations such as atmospheric dispersion modeling and analysis and prediction of the performance of engineered systems. These codes are continually subjected to automated regression test suites consisting of verified and validated expected results. Code is managed in repositories. Experience level of developers is high in the knowledge domain, platforms, and languages used. Code size of the multi-physics code used in this study was 578,242 lines excluding comment and blank lines or 5538.7 function points. Languages were 70% C++, 20% C, and 10% Fortran. The code has 130 users and a development team of 14 and an embedded SQE. The code has achieved 100% prime feature test coverage, 73.6% functional test coverage, and 71.5% statement test coverage. The average cyclomatic complexity of the code was 6.25. The codes have evolved over 10 years. Research codes are challenging because there is a desire to balance agility with discipline as well as compliance with DOE standards. Agility is important to allow experimentation with new algorithms and addition of the latest physics features. Discipline is important to increase the quality of the codes. Automation of processes and defect prevention/detection are deployed throughout the software development process. Since resarch codes are a small segment of the software industry, not much information exists in terms of reliability studies on these types of codes. This paper describes attempts to determine the goodness of these research codes. Goodness defined as both correctness of the codes and their fault densities. Correctness is determined by user interviews, peer review; feature based automated testing, and coverage measurement. This

      205 Tl has been previously proposed as a geological detector for solar neutrinos, making use of the reaction 205 Tl(nu, e - ) 205 Pb with a neutrino threshold of only approx. = 43 keV. We report on an experiment performed to study the feasibility of detecting radioactive 205 Pb nuclei (T/sub 1/2/ = 15 million years) at very low concentrations using the recently developed technique of accelerator mass spectrometry. Employing the high-energy ion beams of good quality from the UNILAC heavy-ion accelerator at the GSI Darmstadt, we are able to demonstrate a suppression of neighbouring isotopes to better than 1 in 10 16 and of neighbouring elements to about 1 in 10 3 . While these results are very encouraging, the minimum number of atoms detectable is still severely limited by the efficiency of producing multiply-charged ions from present ion sources. Future improvements in ion-source performance are briefly discussed

This paper covers the experience gained in the past ten refueling outages for the two BWR units at the First Nuclear Power Station of Taipower. The key to optimizing both the cost and schedule of a refueling outage is to maintain a high level of quality workmanship. The outage management in planning, scheduling, preparation, coordination, and cooperation, accompanied by the qualified in-house capability and sufficient outside support, have placed the refueling outages at the FNPS in a well controlled situation and have established the capacity factors of these two BWR units at a level which is 20% higher than the world average in the past years

      Microgravity experiments on the Constrained Vapor Bubble Heat Exchanger, CVB, are being developed for the International Space Station. In particular, we present results of a precursory experimental and theoretical study of the vertical Constrained Vapor Bubble in the Earth's environment. A novel non-isothermal experimental setup was designed and built to study the transport processes in an ethanol/quartz vertical CVB system. Temperature profiles were measured using an in situ PC (personal computer)-based LabView data acquisition system via thermocouples. Film thickness profiles were measured using interferometry. A theoretical model was developed to predict the curvature profile of the stable film in the evaporator. The concept of the total amount of evaporation, which can be obtained directly by integrating the experimental temperature profile, was introduced. Experimentally measured curvature profiles are in good agreement with modeling results. For microgravity conditions, an analytical expression, which reveals an inherent relation between temperature and curvature profiles, was derived.

      Flammable gases are often used in detectors for physics experiments. The storage, distribution and manipulation of such flammable gases present several safety hazards. As most flammable gases cannot be detected by human senses, specific well-placed gas detection systems must be installed. Following a request from the user group and in collaboration with CERN safety officers, risk analyses are performed. An external contractor, who needs to receive detailed user requirements from CERN, performs the installations. The contract is passed on a guaranteed results basis. Co-ordination between all the CERN groups and verification of the technical installation is done by ST/AA/AS. This paper describes and focuses on the structured methodology applied to implement such installations based on goal directed project management techniques (GDPM). This useful supervision tool suited to small to medium sized projects facilitates the task of co-ordinating numerous activities to achieve a completely functional system.

      The Pentomic experience is presented in outline form. The subject is discussed under the following topics: context, objectives, description, assessment, and lessons. The context included President Eisenhower's open-quotes new lookclose quotes strategy and service rivalry for nuclear share. The objectives for the Pentomic Division included dual capability with nuclear emphasis, strategic mobility, smaller, and major organizational changes. The Pentomic Division is described as a separate division in which the infantry battle group is a basic building block. The Pentomic Division was designed to be dual-capable in both conventional and nuclear warfare and was assessed or perceived to be neither. The possible reasons for the failure of the concept were: problem too hard, wrong solution, premature solution, weak implementation, and overambitious goals

An extensive description of the Moessbauer Effect Spectroscopy (MES) technique is given. The results of MES experiments at room temperature for FeX alloys (X stands for one of the sp-elements) and impurity concentrations of 1, 3 and 5 a/o are presented. Through temperature dependant measurements the hyperfine fields H ((m,n)T) at iron nuclei in different surroundings are obtained. The change of the Curie temperature of the various dilute iron-base alloys, with respect to pure iron, as a function of the impurity concentration is investigated. Average magnetic hyperfine fields and isomer shifts measured at 119 Sn nuclei in Fe 119 Sn are discussed

      1979-01-01

      ICE was built in 1977, using the modified bending magnets of the g-2 muon storage ring (see 7405430). Its purpose was to verify the validity of stochastic and electron cooling for the antiproton project. Stochastic cooling proved a resounding success early in 1978 and the antiproton project could go ahead, now entirely based on stochastic cooling. Electron cooling was experimented with in 1979. The 26 kV equipment is housed in the cage to the left of the picture, adjacent to the "e-cooler" located in a straight section of the ring. With some modifications, the cooler was later transplanted into LEAR (Low Energy Antiproton Ring) and then, with further modifications, into the AD (Antiproton Decelerator), where it cools antiprotons to this day (2006).

      1993-01-01

      There were three oral sessions and one poster session for Workshop C1 on Gravitational Wave Experiments. There was also an informal experimental roundtable held one after- noon. The first two oral sessions were devoted mainly to progress reports from various interferometric and bar detector groups. A total of 15 papers were presented in these two sessions. The third session of Workshop C1 was devoted primarily to theoretical and experimental investigations associated with the proposed interferometric detectors. Ten papers were presented in this session. In addition, there were a total of 13 papers presented in the poster session. There was some overlap between the presentations in the third oral session and the posters since only two of the serious posters were devoted to technology not pertinent to interferometers. In general, the papers showed the increasing maturity of the experimental aspects of the field since most presented the results of completed investigations rather than making promises of wonderf...

      The rapid expansion of remote sensing capability over the last two decades will take another major leap forward with the advent of the Earth Observing System (Eos). An approach is presented that will permit experiments and demonstrations in onboard information extraction. The approach is a non-intrusive, eavesdropping mode in which a small amount of spacecraft real estate is allocated to an onboard computation resource. How such an approach allows the evaluation of advanced technology in the space environment, advanced techniques in information extraction for both Earth science and information science studies, direct to user data products, and real-time response to events, all without affecting other on-board instrumentation is discussed.

      The Cibola Flight Experiment (CFE) is an experimental small satellite carrying a reconfigurable processing instrument developed at the Los Alamos National Laboratory that demonstrates the feasibility of using FPGA-based high-performance computing for sensor processing in the space environment. The CFE satellite was launched on March 8, 2007 in low-earth orbit and has operated extremely well since its deployment. The nine Xilinx Virtex FPGAs used in the payload have been used for several high-throughput sensor processing applications and for single-event upset (SEU) monitoring and mitigation. This paper will describe the CFE system and summarize its operational results. In addition, this paper will describe the results from several SEU detection circuits that were performed on the spacecraft.

      This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

    12. Industrial experience with titanium

      1997-09-01

      Titanium is a reference material for the construction of waste containers in the Canadian Nuclear Fuel Waste Management Program. It has been in industrial service for over 30 a, often in severe corrosion environments, but it is still considered a relatively exotic material with limited operating history. This has arisen because of the aerospace applications of this material and the misconception that the high strength-to-weight ratio dominates the choice of this material. In fact, the advantage of titanium lies in its high reliability and excellent corrosion resistance. It has a proven record in seawater heat exchanger service and a demonstrated excellent reliability even in polluted water. For many reasons it is the technically correct choice of material for marine applications. In this report we review the industrial service history of titanium, particularly in hot saline environments, and demonstrate that it is a viable waste container material, based upon this industrial service history and operating experience.

The analyses show that the women who have the highest divorce rates grew up in a big city, cohabited before marriage (and are or were religious), married before age 21 in the period 1980-88 and had a child before, or within six months after, the wedding. On the basis of these results, it is estimated that 20% will experience divorce within the first five years of their marriage.

    14. Reviewing operational experience feedback

      International Nuclear Information System (INIS)

      1991-04-01

      The purpose of this document is to provide detailed supplementary guidance to OSART experts to aid in the evaluation of operational experience feedback (OEF) programmes at nuclear power plants. The document begins by describing the objectives of an OEF programme. It goes on to indicate preparatory work and investigatory guidance for the expert. Section 5 describes attributes of an excellent OEF programme. Appended to these guidelines are examples of OEF documents from various plants. These are intended to help the expert by demonstrating the actual implementation of OEF in practice. These guidelines are in no way intended to conflict with existing national regulations and rules. A comprehensive OEF programme, as described in Section 2, would be impossible to evaluated in detail in the amount of time typically allocated for assessing OEF in an OSART review. The expert must use his or her time wisely by concentrating on those areas that appear to be the weakest

      2016-06-09

      This document summarizes the Bumpy Torus Experiment as a viable fusion reactor concept. Conclusions reached include the following: In 30 years, order-of-magnitude technological advances have occurred in multiple areas of plasma heating and confinement. The ORNL bumpy torus of the 1970s was technology limited. Now that ITER is technology limited, an alternate concept is needed. A device built on such a concept should be current free, CW, modular, have a gentle shutdown, and demonstrable stability. The bumpy torus meets or has the potential to meet all of these criteria. Earlier, stability was not possible due to power limits; it has not been fully tested. It is time to revisit the bumpy-torus concept with a modest new machine.

      The COMPASS Experiment at the CERN SPS has a broad physics program focused on the study of the spin structure of the nucleon and on hadron spectroscopy. Key measurements for the spin program are the gluon contribution to the spin of the nucleon, semi-inclusive measurements, and the first measurement of the transverse structure function $\\Delta_{T}q(x)$. Its state-of-the-art apparatus consists of a two-stage large acceptance spectrometer designed for high data rates and equipped with high-resolution tracking, particle identification and electromagnetic and hadronic calorimetry. The first year of physics run (2002) was devoted to the spin programme, using a polarised $\\mu^{+}$ beam at 160 GeV/c and a polarised $^{6}$LiD target.

      Full Text Available The aim of this paper is to describe the experience of careeroriented activities carried out with students of schools in developed and developing countries. Career Guidance in Russia, despite the vast experience of its implementation, is experiencing serious difficulties. In this regard, it is important to take into account the international experience career-oriented activities, such as in the developed countries of North America and the European Union as well as in several Asian countries with rapidly growing economies and a large demographic potential, taking into account the best variants for the Russian education system. Methods. The experience of career-oriented work undertaken with pupils of the USA, Canada, Israel, France, UK, Germany, Denmark, Sweden, Japan, Singapore, China and India is shown on the basis of the comparative analysis of different publications and information sources. The author has made an attempt to generalize the principles of psycho-pedagogical and administrative assistance in professional self-determination of senior pupils abroad. Scientific novelty. The approaches to career-oriented activities in countries with different levels of economic development are compared for the first time. Some principles are revealed. Firstly, the higher the income level per capita in the country, the greater attention is given to vocational guidance. The politics in the developed countries is based on interests of the individual: children’s acquaintance with the world of professions begins already at younger school and the moment of definitive selfdetermination is postponed till the end of their senior stage of education; the possibility of direction change of professional preparation in case of detection of discrepancy of qualities of the pupil to originally selected profile is provided. Career-oriented activity in developing countries, on the contrary, is rigidly coordinated to requirements of economy and a labour market

      The Joint European Torus (JET) is an experiment in nuclear fusion research which was planned as a joint effort between national research laboratories and Euratom. Before approval was given for it to be built it became a political football in the European Communities. This book describes the background against which JET was conceived, designed and planned. It gives a chronological account of the political imbroglio which followed between 1975 and 1978 and indicates how close the project came to collapse at one point. In addition to the two years' delay caused by Ministerial conflicts over its siting, the project suffered many compromises in its financing, its staffing and its organisation. An account is given of the unique structure of the European Communities and its procedures, which shows how idealism constantly faces reality. The role of Euratom is discussed, taking into account the difference between its approach to applications of nuclear fission as opposed to those of nuclear fusion. (author)

      The 21 August 2017 solar eclipse was an excellent opportunity for electronics and science enthusiasts to collect data during a fascinating phenomenon. With my recent personal interest in Raspberry Pis, I thought measuring how much the temperature and illuminance changes during a total solar eclipse would be fun and informational.Previous observations of total solar eclipses have remarked on the temperature drop during totality. Illuminance (ambient light) varies over 7 orders of magnitude from day to night and is highly dependent on relative positions of Sun, Earth, and Moon. I wondered whether totality was really as dark as night.Using a Raspberry Pi Zero W, a Pimoroni Enviro pHAT, and a portable USB charger, I collected environmental temperature; CPU temperature (because the environmental temperature sensor sat very near the CPU on the Raspberry Pi); barometric pressure; ambient light; R, G, and B colors; and x, y, and z acceleration (for marking times when I moved the sensor) data at a ~15 second cadence starting at about 5 am until 1:30 pm from my eclipse observation site in Glendo, WY. Totality occurred from 11:45 to 11:47 am, lasting about 2 minutes and 30 seconds.The Raspberry Pi recorded a >20 degree F drop in temperature during the eclipse, and the illuminance during totality was equivalent to twilight measurements earlier in the day. A limitation in the ambient light sensor prevented accurate measurements of broad daylight and most of the partial phase of the eclipse, but an alternate ambient light sensor combined with the Raspberry Pi setup would make this a cost-efficient set-up for illuminance studies.I will present data from the ambient light sensor, temperature sensor, and color sensor, noting caveats from my experiments, lessons learned for next time, and suggestions for anyone who wants to perform similar experiments for themselves or with a classroom.

      When a high-voltage direct-current is applied to two beakers filled with water or polar liquid dielectrica, a horizontal bridge forms between the two beakers. This experiment was first carried out by Lord Armstrong in 1893 and then forgotten until recently. Such bridges are stable by the action of electrohydrodynamic (EHD) forces caused by electric field gradients counteracting gravity. Due to these gradients a permanent pumping of liquid from one beaker into the other is observed. At macroscopic scale several of the properties of a horizontal water bridge can be explained by modern electrohydrodynamics, analyzing the motion of fluids in electric fields. Whereas on the molecular scale water can be described by quantum mechanics, there is a conceptual gap at mesoscopic scale which is bridged by a number of theories including quantum mechanical entanglement and coherent structures in water - theories that we discuss here. Much of the phenomenon is already understood, but even more can still be learned from it, since such "floating" liquid bridges resemble a small high voltage laboratory of their own: The physics of liquids in electric fields of some kV/cm can be studied, even long time experiments like neutron or light scattering are feasible since the bridge is in a steady-state equilibrium and can be kept stable for hours. It is also an electro-chemical reactor where compounds are transported through by the EHD flow, enabling the study of electrochemical reactions under potentials which are otherwise not easily accessible. Last but not least the bridge provides the experimental biologist with the opportunity to expose living organisms such as bacteria to electric fields without killing them, but with a significant influence on their behavior, and possibly, even on their genome.

      The Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), USA has provided scientific data management support for the US Department of Energy and international climate change science since 1982. Among the many data activities CDIAC performs are design and implementation of the data systems. One current example is the data system and network for SPRUCE experiment. The SPRUCE experiment (http://mnspruce.ornl.gov) is the primary component of the Terrestrial Ecosystem Science Scientific Focus Area of ORNL's Climate Change Program, focused on terrestrial ecosystems and the mechanisms that underlie their responses to climatic change. The experimental work is to be conducted in a bog forest in northern Minnesota, 40 km north of Grand Rapids, in the USDA Forest Service Marcell Experimental Forest (MEF). The site is located at the southern margin of the boreal peatland forest. Experimental work in the 8.1-ha S1 bog will be a climate change manipulation focusing on the combined responses to multiple levels of warming at ambient or elevated CO2 (eCO2) levels. The experiment provides a platform for testing mechanisms controlling the vulnerability of organisms, biogeochemical processes and ecosystems to climatic change (e.g., thresholds for organism decline or mortality, limitations to regeneration, biogeochemical limitations to productivity, the cycling and release of CO2 and CH4 to the atmosphere). The manipulation will evaluate the response of the existing biological communities to a range of warming levels from ambient to +9°C, provided via large, modified open-top chambers. The ambient and +9°C warming treatments will also be conducted at eCO2 (in the range of 800 to 900 ppm). Both direct and indirect effects of these experimental perturbations will be analyzed to develop and refine models needed for full Earth system analyses. SPRUCE provides wide range continuous and discrete measurements. To successfully manage SPRUCE data flow

      López-Caniego, Marcos

      The QUIJOTE (Q-U-I JOint Tenerife) Experiment† (Rubiño-Martín et al. 2010)) is observing the polarization of the Cosmic Microwave Background and other Galactic and extragalactic signals at medium and large angular scales in the frequency range of 10-40 GHz. This experiment is going to provide valuable information about the polarization properties of synchrotron and anomalous microwave emission at these frequencies. It consists of two telescopes and three instruments located at the the Teide Observatory (2400 m) in Tenerife, Canary Islands, Spain. This project has two phases: Phase I, the first telescope (QT1) and a multi-frequency instrument (MFI) are in operations since November 2012 observing between 10 and 20 GHz. A second instrument (TGI) with 31 polarimeters working at 30 GHz is expected to start operations in Autumn 2015 and will be devoted to primordial B-mode science. This instrument will include a fixed polariser and 90 and 180 phase switches to generate four polarization states to minimize the different systematics in the receiver; Phase II, a second QUIJOTE telescope (QT2), already in operation, and a third instrument (FGI) with 40 polarimeters working at 41 GHz, safely below the 60-GHz oxygen absorption band, will significantly increment the sensitivity of the QUIJOTE project to detect the r parameter (tensor-to-scalar ratio). The reason for this is not only the significant reduction of noise due to the number of polarimeters that will incorporate but also the lower synchrotron signal from our galaxy expected at these higher frequencies. The maps obtained with the multi-frequency instrument (10-20 GHz), in combination with data from other experiments like Planck and the VLA, will be used to clean the diffuse and compact foreground emission at 30 and 40 GHz, the cosmological channels. After three years of effective observations we expect to reach the required sensitivity to detect a primordial gravitational-wave component if the tensor

      TARN is a storage ring of low energy ions (T sub(N) -- 10 MeV/u) constructed in 1979 to verify the feasibility of intensity multiplication proposed at NUMATRON project. The mean radius and maximum magnetic rigidity of the ring are 5.06 m and 11.8 kG.m, respectively. Magnet system based on a strong focusing FODO lattice is composed of 8 dipole and 16 quadrupole magnets. Additional 12 sextupole magnets are also installed for chromaticity control. Intensity increase by the multi-turn injection is 20 times with the dilution factor of 2.0 in horizontal transverse phase space. Injected beams are RF captured with the frequency around 8 MHz and moved inner side of the ring by RF deceleration as large as -- 5 % in Δp/p. Beam intensity increases linearly up to around 20 stackings with the capture efficiency of 80 % and 30 Hz repetition rate. Dilution factor of the longitudinal phase space is measured at 1.8. Thus about 300 times total intensity increase has been attained. The e-folding beam life time of 7 MeV proton is measured at 400 s for the vacuum pressure of 1 x 10 -10 Torr. Stochastic momentum cooling experiment of 7 MeV proton has been performed. A feed-back system based on the 'Notch-Filter' method has been adopted for its simplicity and characteristics suitable for lower beam intensity. Cooling time for the 7 MeV proton beam with the intensity of 10 8 is estimated at 19 s for optimum cooling rate with the system gain of 105 dB, while the system gain as large as 111 dB has been achieved without self-oscillation of the electronics system. From the beam experiment, the cooling time of 10 8 proton beam with fractional momentum spread of 1.4 x 10 -2 is measured at --20 sec with the system gain of 97 db. (author)

      Nepal's panchayat system of partyless democracy with 5 class organizations of peasants, youth, women, labor, and ex-servicemen, is an effort in community development. Panchayat training centers train panchayat secretaries and women workers. The government tried out the Mobile Training Scheme (MTS) methodology to train panchayat training center instructors in 1974-75 when 5 courses were given for 76 participants. The MTS methodology included several new assumptions: the necessity of knowing the field situation, a realistic problem solving orientation, learning by actual field experience, and interdependence rather than teacher dependence. The multipurpose role of the panchayat secretary was studied and clarified. Role performance led to the development of a realistic job description from which a task-focused curriculum could be developed. Field work tools included maintaining a daily diary, collecting information and developing a present and past project history, and compiling a village profile. The trainees played the roles of front line workers in the field when they returned from the villages played the roles of supervisors and trainers. The key concept in the multipurpose role of the panchayat secretary was collaboration. The panchayat secretary-trainee had to understand the social roles in the community, and work within the social context to get cooperation from other agencies, village and informal organizations, in order to fulfill their role. Tutorial and team teaching methods were used to provide partnership in learning; the old roles of lecturer and lectured were seen as ineffective when actual field experience was the criteria. The role performing and role analysis group analyzed the front line workers' roles and evolved job descriptions which led to course outlines. The teaching methods and materials group produced indigenous teaching materials for classroom use based on problems faced in the field. The action research and technical collaboration groups

The author of the article analyzes the structure of monitoring indicators and provides a brief interpretation of research findings that reflect social wellbeing and social perception trends. In addition, the paper analyzes people’s attitude toward the activities of federal and regional authorities, trends in social well-being, consumer sentiment and also the complex indicator – the index of public sentiment in the region – developed by ISEDT RAS researchers. The results of sociological studies carried out at ISEDT RAS correlate with the dynamics of the all-Russian public opinion polls conducted by the Institute of Sociology of the Russian Academy of Sciences, the Russian Public Opinion Research Center (VCIOM, Levada-Center, etc. They indicate that Russian society gradually adapts to new conditions of life after the collapse of the USSR. Besides, opinion polls show the most important features of the post-Soviet Russian history at its present stage; they are associated with the intensification of international political relations, the consequences of the “Crimean spring” and the new challenges Russia’s economy is facing now. The article concludes that as global community, of which Russian society is part, is evolving, sociological knowledge begins to play an increasingly important role in administration and national security; this is associated with the greater importance attached to intangible development factors. Therefore, a necessary prerequisite for administration effectiveness in all its stages is to implement the results of sociological research on social

      The plasma stabilization experiment is an effort to enhance stability in a mirror-confined plasma by trapping cold ions with rf fields applied near the mirror throats. Nagoya Type 3 antennas, coupled to a 60 kW rf power supply are mounted in the throats of the UTRC baseball magnet. An external washer gun provides a source of plasma for both streaming and confined plasma tests. Results show a strong stoppering effect on streaming plasmas and a marginal effect on confined plasmas. Theoretical calculations provide an explanation for the experimental observations. The field generates a ponderomotive force acting on the electrons. The resultant improvement in electron confinement changes the ambipolar potential and inhibits the flow of ions through the mirror throat. Criteria are derived for the validity of this trapping concept. The requisite field strengths are significantly lower than those required to trap ions directly. Scaling laws are developed for application of cold ion trapping to large mirror devices containing dense plasmas. The use of slow-wave antenna structures operated at frequencies above the lower hybrid frequency is recommended for these applications.

      The Sustained Spheromak Physics Experiment, SSPX, will study spheromak physics with particular attention to energy confinement and magnetic fluctuations in a spheromak sustained by electrostatic helicity injection. In order to operate in a low collisionality mode, requiring T e >100 eV, vacuum techniques developed for tokamaks will be applied, and a divertor will be used for the first time in a spheromak. The discharge will operate for pulse lengths of several milliseconds, long compared to the time to establish a steady-state equilibrium but short compared to the L/R time of the flux conserver. The spheromak and helicity injector ('gun') are closely coupled, as shown by an ideal MHD model with force-free injector and edge plasmas. The current from the gun passes along the symmetry axis of the spheromak, and the resulting toroidal magnetic field causes the safety factor, q, to diverge on the separatrix. The q-profile depends on the ratio of the injector current to spheromak current and on the magnetic flux coupling the injector to the spheromak. New diagnostics include magnetic field measurements by a reflectometer operating in combined O- and X-modes and by a transient internal probe (TIP). (author)

      Full Text Available The contemporaneity is characterized by instability and diversity calling into question certainties and truths proposed in modernity. We recognize that the reality of things and phenomena become effective as a set of events, interactions, retroactions and chances. This different frame extends the need for revision of the epistemological foundations that sustain educational practices and give them sense. The complex thinking is an alternative option for acting as a counterpoint to classical science and its reductionist logic and knowledge compartmentalization, as well as to answer to contemporary epistemological and educational challenges. It aims to associate different areas and forms of knowledge, without, however merge them, distinguishing without separating the several disciplines and instances of the realities. This study, in theoretical references, highlights the relevance of complex approaches to support formative experiences because also able to produce complexities in reflections about educational issues. We conclude that formative possibilities from complexity potentialize the resignification of human’s conception and the understanding of its singularity in interdependence; The understanding that pedagogical and educational activities is a constant interrogation about the possibilities of knowing the knowledge and reframe learning, far beyond knowing its functions and utilitarian purposes; and, as a formative possibility, places us on the trail of responsibility, not as something eventual, but present and indicative of freedom to choose to stay or go beyond.

      JRC-ETHEL has chosen as the principle objective of its research program the improvement of protection measures in facilities handling large amounts of tritium. Technically, this involves investigating and assessing tritium propagation modes and transfer pathways in materials, components, equipment, and process plants. The experiment research work to be performed in ETHEL will basically aim at investigating: (1) Loss mechanisms by identifying physico-chemical parameters such as adsorption/desorption rates, permeation rates, leakages of materials for fusion reactors and the effects of potential remedies like permeation barriers under process-like conditions. (2) Multiple containment systems and fluid clean-up concepts under normal and accidental conditions. (3) Methods for solid waste handling, treatment, conditioning, and final disposal. (4) Techniques for tritium control, monitoring, and surveillance over the whole concentration range during both normal and accidental conditions and maintenance activities. With the availability of two open-quotes climate chambers,close quotes the small and large caissons of 5 and 350 m 3 volume respectively, ETHEL is especially suited for benchmark and scale-up tests of many kinds of large gas volumes treatment system. This will help to close the gap between laboratory-scale results and plant-size design specifications and represents an important source of information for designers (NET, ITER) and regulatory authorities

      Induced excess pore water pressures resulting from the insertion of piezometer probes of 8-mm (0.31-in.) diameter and a simulated waste canister of 102-mm (4.0-in.) diameter and the dissipation of these excess pressures were measured during deep-ocean component tests of the In Situ Heat Transfer Experiment (ISHTE). The sediment at the Pacific test site 1100 km north of Oahu, Hawaii, is an illitic clay. Insertion-induced excess pore pressures were found to agree well with those predicted by models. Several aspects of the induced excess pressure dissipation were evaluated including the effects of probe and heater diameter, distal excess pore pressure response, and the synergistic excess pore pressure response from multiple insertions. The dissipation of induced excess pressures measured at each piezometer is predicted well by theory. The same analytical models predict the excess pore pressure history measured at the piezometers in response to the waste canister insertion. Present models were evaluated that predict insertion excess pressures and their dissipation rate at the probe surface and distal, far field, points

      Among the various techniques to minimize corrosion products deposition on out of core areas, surface polishing has been researched. The attention of French partners was drawn to this technique and a test was conducted at Chinon B1 NPP in 1984 using six manway covers with various surface finishing (mechanical polishing, electropolishing, mechanical plus electropolishing/on reference). On the basis of the good results obtained and with beneficial cost considerations the electropolishing of SGCH has been decided for new EDF reactors. Once the decision was made feasibility and qualifications programs were developed. Taking into account the promising results obtained, EDF asked FRAMATOME to perform the first electropolishing operation on one steam generator channel head at Nogent 1 in 1987. Since 1988 the French experience consists of the electropolishing of 4SG at Nogent 2, 4SG at Cattenom 3, 4SG at Penly 1 and 4SG at Golfech 1 (NPP), and is perfectly satisfactory. The industrial operation provides excellent polishing and does not create undesired effects. The French partners are now thinking of a new device which could be realised at FRAMATOME especially for steam generator replacement. (author)

      In order to conduct the shield design calculation of the Large Hadron Collider (LHC) under planning in CERN at present, the radiation group of CERN uses FLUKA (Monte Carlo High Energy Radiation Transport Code). Here is introduced on outline of FLUKA and use experience of FLUKA in the LHC-B detector shield design calculation in LHC plan. FLUKA can be said to be the highest standard in the high energy radiation transportation code of the world at every points of the physical model, the Monte Carlo calculation technique and the convenience at usage of the code. In Japan Atomic Energy Research Institute (JAERI), a using right of FLUKA for the target neutronics and facility shielding design at the neutron science research center is obtained and it seems to be an effective design means in these future designs. However, because FLUKA is allowed a limited opening and no own verification on the code, it will be supposed to be a large problem on investigating a validity in design. (K.G.)

      ascination with materials and chemical change is a hallmark of chemists, and it is also an important pedagogical tool. A fringe benefit of editing JCE is that I encounter so many nice people who send interesting and helpful communications. One of the first of these to cross my desk this year was from E. J. Behrman, who recommended that I read and call to your attention "Brilliant Light: A Chemical Boyhood" by Oliver Sacks, noted neurologist and author. It appeared in the December 20, 1999, issue of The New Yorker and is well worth your time and effort to find and read. Sacks's reminiscence of his boyhood interest in chemistry is fascinating. His obvious love of our science is inspiring. And he has expressed both in words that are brilliantly chosen and a joy to read. In a profile of Sacks that appeared in Chemical and Engineering News (January 10, 2000), Madeleine Jacobs relates that he is writing a book on his boyhood encounters with chemistry (to be published by Alfred A. Knopf). I am looking forward to that with great anticipation. During 1999 he also wrote an article on the periodic table in the New York Times Magazine (April 18) and an op-ed piece on chemistry sets in the New York Times (May 13). In the latter he describes how hard it is these days for a nonchemist, especially a young one, to obtain chemicals to experiment with. Chemistry sets are not what they used to be! Sacks's writings contain important messages for all of us who teach chemistry and all who are involved in piquing students' interest in our subject. A brief excerpt from his New Yorker article illustrates my point. I knew zinc--the dull, slightly bluish birdbath in the garden was made of zinc--and tin, from the heavy tinfoil in which sandwiches were wrapped for a picnic. My mother showed me that when tin or zinc was bent it uttered a special "cry." "It's due to deformation of the crystal structure," she said, forgetting that I was five and could not understand her--and yet her words made me

      1986-01-01

      A variety of rf experiments are being conducted on PLT in order to explore rf techniques which could improve tokamak performance parameters. Of special importance are the studies of ion Bernstein wave (IBW) heating, lower hybrid MHD stabilization and electron heating, down-shifted electron cyclotron heating, and fast wave current drive. Ion Bernstein wave heating results at modest power indicate that the particle confinement time could be enhanced relative to that for fast wave heating in the ion cyclotron range of frequencies (ICRF) and neutral beam heating. At these power levels a conclusive determination of energy confinement scaling with power cannot yet be given. Central sawtooth and m = 1 MHD stabilization is being obtained with centrally peaked lower hybrid (LH) current drive and the central electron temperature is peaking to values (approx.5 keV) well outside the bounds of ''profile consistency.'' In this case the electron energy confinement is apparently increased relative to the ohmic value. The production of relativistic electrons via heating at the down-shifted electron cyclotron (EC) frequency is found to be consistent with theoretical predictions and lends support to the use of this method for heating in relatively high magnetic field devices

      Last Monday, the new CERN Machine Advisory Committee (CMAC) met for the first time, and we had good news to tell its members. Over the weekend, injection tests for both LHC beams were successfully carried out. In other words, we’ve had beam in the LHC for the first time since September 2008. That’s a good feeling, but it’s no reason for complacency. There’s still a long way to go before first physics at the new energy frontier. As the Bulletin has reported over recent weeks, we’re gathering a lot of positive experience with the new quench detection and protection system (QPS), which is already allowing us to monitor the LHC far better than we were able to in the past. So far, the QPS for three of the LHC’s eight sectors has been put through its paces, and we’ve also power tested those sectors to 2000 amperes, the equivalent of around 1.2 TeV per beam. The next step is to slowly increase the current to 4000 amperes, and...

      Full Text Available It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote laboratories have tackled this issues providing online reusable and shared workbenches unconstrained by neither geographical nor time considerations. Thereby, they have extremely proliferated among universities and integrated into engineering curricula over the last decade. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR, on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well. In addition, the paper address the next challenges and future works carried out at several universities within the VISIR community.

    18. My experience in arbitration

      Directory of Open Access Journals (Sweden)

      Claude Witz

      2011-12-01

      Full Text Available This paper deals with the nature of arbitration as one of the alternatives in dispute resolution processes different from mediation and conciliation, and obviously, from judicial adjudication. Unlike a mediator or a conciliator, an arbitrator is empowered to pass a judgement, like a court. In other words, the arbitrator will render a decision which is binding for the parties. The arbitrator has the jurisdictio, like a judge. Although the office of a judge and an arbitrator is the same, the source of their power is different. The judge’s power originates from a State, whereas the power of the arbitrator results primarily from a contract. Unlike the court, the arbitrator lacks the imperium, i.e. the power to make the award enforceable. When a party refuses to enforce the award, enforceability can only be provided by the judge or an authority of the state where the award has to be enforced. In a certain sense the state thus provides the back up for the arbitration system. This paper presents personal thoughts drawn from the author’s professional experience as an arbitrator in Franco-German disputes.

      To explore the experience and value of overlay tympanoplasty. Sixty-three ears with overlay tympanoplasty were reviewed and followed up for the external auditory canal, tympanic membrane and hearing. The diseases of the patients included middle ear cholesteatoma in 25 ears and chronic suppurative otitis media in 38 ears. The surgical techniques involved three kinds: overlay tympanoplasty, overlay tympanoplasty with canal wall up mastoidectomy and overlay tympanoplasty with canal wall down mastoidectomy. In middle ear cholesteatoma and suppurative otitis media patients, the case received the three techniques are 4, 17, 4 ears and 19, 18, 1 ears respectively. All patients gained stage I incision cure. Followed up for 0.5 to 3.5 years respectively, the external auditory canal was wide and tympanic membrane gained a good shape. The hearing in all case kept intact or increased while hearing decrease did not occur. Complications were free in patients with punctual visit. Overlay tympanoplasty has positive significance in treating the chronic otitis media with the merits of standard procedure, sufficient operative field and thorough erosion elimination.

      The state of stress in a subterranean rock mass has classically been assumed to be constant at best. In soil with a high clay content, preconsolidation and drainage methods can lead to more stable foundation material, but methods for engineering the stresses in large masses of rock are not well known. This paper shows the results from an experiment designed to alter the in situ rock stress field in an oil shale mine. This was done by hydrofracturing the rock by use of a packed-well injection system and then propping the crack open with a thixotropic gel, which slowly hardened to the consistency of cement. Successive hydrofracture and high-pressure grouting resulted in an overstressed region. Well-head injection pressures, surface tilts, injection rates, and subterranean strains were measured and recorded on floppy disk by a Z-80 microprocessor. The results were then transmitted to the large computer system at the Los Alamos Scientific Laboratory (LASL). To put the data in a more useful form, computer-generated movies of the tilts and strains were made by use of computer graphics developed at LASL. The purpose of this paper is to present results from the Single Large Instrumented Test conducted in the Colony Oil Shale Mine near Rifle, Colorado. 13 figures

      The Spectral and Polarimetric Imagery Collection Experiment (SPICE) is a collaborative effort between the US Army ARDEC and ARL that is focused on the collection of mid-wave and long-wave infrared imagery using hyperspectral, polarimetric, and broadband sensors. The objective of the program is to collect a comprehensive database of the different modalities over the course of 1 to 2 years to capture sensor performance over a wide variety of weather conditions, diurnal, and seasonal changes inherent to Picatinny's northern New Jersey location. Using the Precision Armament Laboratory (PAL) tower at Picatinny Arsenal, the sensors will autonomously collect the desired data around the clock at different ranges where surrogate 2S3 Self-Propelled Howitzer targets are positioned at different viewing perspectives in an open field. The database will allow for: 1) Understanding of signature variability under adverse weather conditions; 2) Development of robust algorithms; 3) Development of new sensors; 4) Evaluation of polarimetric technology; and 5) Evaluation of fusing the different sensor modalities. In this paper, we will present the SPICE data collection objectives, the ongoing effort, the sensors that are currently deployed, and how this work will assist researches on the development and evaluation of sensors, algorithms, and fusion applications.

      The Spectral and Polarimetric Imagery Collection Experiment (SPICE) is a collaborative effort between the US Army ARDEC and ARL for the collection of mid-wave and long-wave infrared imagery using hyperspectral, polarimetric, and broadband sensors. The objective of the program is to collect a comprehensive database of the different modalities over the course of 1 to 2 years to capture sensor performance over a wide variety of adverse weather conditions, diurnal, and seasonal changes inherent to Picatinny's northern New Jersey location. Using the Precision Armament Laboratory (PAL) tower at Picatinny Arsenal, the sensors will autonomously collect the desired data around the clock at different ranges where surrogate 2S3 Self-Propelled Howitzer targets are positioned at different viewing perspectives at 549 and 1280m from the sensor location. The collected database will allow for: 1) Understand of signature variability under the different weather conditions; 2) Development of robust algorithms; 3) Development of new sensors; 4) Evaluation of hyperspectral and polarimetric technologies; and 5) Evaluation of fusing the different sensor modalities. In this paper, we will present the SPICE data collection objectives, the ongoing effort, the sensors that are currently deployed, and how this work will assist researches on the development and evaluation of sensors, algorithms, and fusion applications.

    4. Results from LHCf Experiment

      The LHCf experiment has taken data in 2009 and 2010 p-p collisions at LHC at $\\sqrt{s} = 0.9$ TeV and $\\sqrt{s} = 7$ TeV. The measurement of the forward neutral particle spectra produced in proton-proton collisions at LHC up to an energy of 14 TeV in the center of mass system are of fundamental importance to calibrate the Monte Carlo models widely used in the high energy cosmic ray (HECR) field, up to an equivalent laboratory energy of the order of $10^{17}$ eV. In this paper the first results on the inclusive photon spectrum measured by LHCf is reported. Comparison of this spectrum with the model expectations show significant discrepancies, mainly in the high energy region. In addition, perspectives for future analyses as well as the program for the next data taking period, in particular the possibility to take data in p-Pb collisions, will be discussed.

      The gloveboxes used for plutonium facilities in Japan and foreign countries have considerable combustibles as their components, so that the fire resistivity of the gloveboxes is a serious problem in the safety evaluation of the facilities. Actually, a big fire having burned gloveboxes occurred in a foreign weapon facility. But the fire in the weapon facility should be distinguished from that in nuclear fuel facilities, since the former handles quite combustible plutonium metal, while the latter handle quite stable plutonium oxide. The countermeasures to fires should be decided, considering the properties and quantity of combustibles around gloveboxes and ventilation systems, as the probability and scale of fires can be presumed from them. From the viewpoint of safety, the experiment on glovebox fires was carried out by the Plutonium Fuel Division, PNC. The experimental conditions are explained. The samples were the acrylic resin panels with four glove ports and a small glovebox currently used. The glovebox showed the considerable fire resistance, and the panel hardly burned. The weakest component of the glovebox against fire was the gloves. The countermeasure to curtain the gloves with an insulating material seemed to be effective. The ventilation of the room and the glovebox worked as fire preventer at least in the first stage of fire. (Kako, I.)

      Three sixteen-year-old students from the International School of Geneva, La Chataigneraie have spent a week finding out about the life of a theoretical physicist at CERN. Student Peter Bishop at the blackboard with Robert Fleischer of Theory Division. Peter Bishop, Sam Schoenholz and Alexander Hultin spent the time with the Theory Unit of the Physics department. The visit was at the suggestion of the students themselves, who are required to undertake work experience at an organization, gaining insights into professional life, as part of their studies. After an introduction to CERN at Microcosm, each student had the opportunity to learn about physics at a level well beyond their current academic training. They were mentored by theoretical physicists who introduced them to the basics of particle physics, discussing physics in general as well as topics such as predicting the mass of the Higgs boson and cosmology. A visit to CMS, guided by Ariane Frey, proved very impressive, but the working conditions of physi...

      Data taking for this experiment was completed in December 1983. The samples include approximately 19,000 (ν) and 11,000 (ν-bar) charged current events. These constitute the largest data set of interactions on free protons. Work published to date includes studies of inclusive structure functions and final state properties, exclusive final states, neutral current cross sections and production of strange and charmed particles. During the past year results have been published on the production of f 2 (1270) and ν 0 (770) mesons in ρp and ρ-barp charged current interactions. In the case of the f 2 this represents the first observation of such production. It is found that the multiplicities are 0.047±0.017 in ρp and 0.17±0.018 in ρ-barp. The f 2 mesons are mostly produced at large hadronic invariant mass W and in the forward hemisphere. The production of ν 0 mesons can be observed with high statistics in both ρp and ρ-barp interactions and the differential cross section studied. The observations are compared with LUND Monte Carlo predictions, which are generally found to be too high. However qualitative features of the data are reproduced. Work continues on a precise determination of the neutral current/charged current ratio, on the study of charged and neutral current structure functions and on the production of strange particles.

    9. Welcome to the experience economy.

      1998-01-01

      First there was agriculture, then manufactured goods, and eventually services. Each change represented a step up in economic value--a way for producers to distinguish their products from increasingly undifferentiated competitive offerings. Now, as services are in their turn becoming commoditized, companies are looking for the next higher value in an economic offering. Leading-edge companies are finding that it lies in staging experiences. To reach this higher level of competition, companies will have to learn how to design, sell, and deliver experiences that customers will readily pay for. An experience occurs when a company uses services as the stage--and goods as props--for engaging individuals in a way that creates a memorable event. And while experiences have always been at the heart of the entertainment business, any company stages an experience when it engages customers in a personal, memorable way. The lessons of pioneering experience providers, including the Walt Disney Company, can help companies learn how to compete in the experience economy. The authors offer five design principles that drive the creation of memorable experiences. First, create a consistent theme, one that resonates throughout the entire experience. Second, layer the theme with positive cues--for example, easy-to-follow signs. Third, eliminate negative cues, those visual or aural messages that distract or contradict the theme. Fourth, offer memorabilia that commemorate the experience for the user. Finally, engage all five senses--through sights, sounds, and so on--to heighten the experience and thus make it more memorable.

      This study aims to describe and analyze healthy individuals' expressed experiences of touch massage (TM). Fifteen healthy participants received whole body touch massage during 60 minutes for two separate occasions. Interviews were analyzed by narrative analysis. Four identifiable storyline was found, Touch massage as an essential need, in this storyline the participants talked about a desire and need for human touch and TM. Another storyline was about, Touch massage as a pleasurable experience and the participants talked about the pleasure of having had TM. In the third storyline Touch massage as a dynamic experience, the informants talked about things that could modulate the experience of receiving TM. In the last storyline, Touch massage influences self-awareness, the participants described how TM affected some of their psychological and physical experiences. Experiences of touch massage was in general described as pleasant sensations and the different storylines could be seen in the light of rewarding experiences. © The Author(s) 2014.

      Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

      I have had the opportunity to support the analytical laboratories in chemical analysis of unknown samples, using Optical Microscopy (OM), Polarizing Light Microscopy (PLM), Fourier-Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEMEDS), and X-ray Powder Diffraction (XPD). I have assisted in characterizing fibers pulled from a spacecraft, a white fibrous residue discovered in a jet refueler truck, brown residue from a plant habitat slated for delivery to the ISS (International Space Station), corrosion on a pipe from a sprinkler, and air filtration material brought back from the ISS. I also conducted my own fiber study in order to practice techniques and further my understanding of background concepts. Furthermore, I had the opportunity to participate in diverse work assignments, where I was assigned to work with other branches of the engineering department for 1-2 days each. The first was in the Materials Science branch where I participated in the construction of the plant habitat intended for use in research aboard the ISS. The second was in the Testing Design branch where I assisted with tensile and hardness testing of over 40 samples. In addition, I have had the privilege to attend multiple tours of the NASA KSC campus, including to the Astronaut Crew Quarters, the VAB (the main area, the Columbia room, and the catwalk), the Visitor Center housing the shuttle Atlantis, the Saturn-V exhibit, the Prototype laboratory, SWAMP WORKS, the Shuttle Landing Facility, the Crawler, and the Booster Fabrication Facility (BFF). Lastly, much of my coursework prepared me for this experience, including numerous laboratory courses with topics diverse as chemistry, physics, and biology.

    15. Experience with hot catchpots

      Energy Technology Data Exchange (ETDEWEB)

      1945-02-02

      The first part of this report was actually a letter regarding the question, ''could the hot circulating pump be omitted when processing pitch at 700 atm.'' It had been stated that the hot circulation pump could be omitted if the quantity of cold letdown was correspondingly increased. The latest experiences with the catchpot at Poelitz showed the following. When running pitch, tar, or petroleum in the liquid-phase stalls, frequent trouble with the hot catchpot was encountered due to the coking. This coking was caused by irregular letdown yield, which could not be avoided due to small temperature fluctuations in the stall. This caused interruption of the uniform flow in the hot catchpot and the deposition of the solids contained in the letdown, largely catalyst solids, due to the asphalt content. Coking of the product was initiated by this concentration of catalyst solids. A perforated double jacket was inserted in the conical part of the catchpot through which about 3000 m/sup 3/ per hour of cold gas was blown in continuously. By this agitation and cooling in the lowest part of the catchpot, catalyst deposits were prevented from forming and the product received a continuous added supply of hydrogen. Another letter was given discussing the same question and an alternate solution. This second letter described Welheim's design for the hot catchpot. It featured introduction of 5000 to 6000 m/sup 3//hr of cold circulating gas into the lower part of the catchpot, and withdrawal of letdown from a point above the gas inlet. The advantages were continued agitation and cooling of the sludge and constant retention of some cold sludge in the catchpot (which evened out throughput and content fluctuations)

    16. GNF2 Operating Experience

      International Nuclear Information System (INIS)

      Schardt, John

      2007-01-01

      GNF's latest generation fuel product, GNF2, is designed to deliver improved nuclear efficiency, higher bundle and cycle energy capability, and more operational flexibility. But along with high performance, our customers face a growing need for absolute fuel reliability. This is driven by a general sense in the industry that LWR fuel reliability has plateaued. Too many plants are operating with fuel leakers, and the impact on plant operations and operator focus is unacceptable. The industry has responded by implementing an INPO-coordinated program aimed at achieving leaker-free reliability by 2010. One focus area of the program is the relationship between fuel performance (i.e., duty) and reliability. The industry recognizes that the right balance between performance and problem-free fuel reliability is critical. In the development of GNF2, GNF understood the requirement for a balanced solution and utilized a product development and introduction strategy that specifically addressed reliability: evolutionary design features supported by an extensive experience base; thoroughly tested components; and defense-in-depth mitigation of all identified failure mechanisms. The final proof test that the balance has been achieved is the application of the design, initially through lead use assemblies (LUAs), in a variety of plants that reflect the diversity of the BWR fleet. Regular detailed surveillance of these bundles provides the verification that the proper balance between performance and reliability has been achieved. GNF currently has GNF2 lead use assemblies operating in five plants. Included are plants that have implemented extended power up-rates, plants on one and two-year operating cycles, and plants with and without NobleChem TM and zinc injection. The leading plant has undergone three pool-side inspections outages to date. This paper reviews the actions taken to insure GNF2's reliability, and the lead use assembly surveillance data accumulated to date to validate

      1983-01-01

      The ESARDA working group on Isotopic Correlation Techniques, ICT and Reprocessing Input Analysis performed an Isotope Correlation Experiment, ICE with the aim to check the feasibility of the new technique. Ten input batches of the reprocessing of the KWO fuel at the WAK plant were analysed by 4 laboratories. All information to compare ICT with the gravimetric and volumetric methods was available. ICT combined with simplified reactor physics calculation was included. The main objectives of the statistical data evaluation were detection of outliers, the estimation of random errors and of systematic errors of the measurements performed by the 4 laboratories. Different methods for outlier detection, analysis of variances, Grubbs' analysis for the constant-bias model and Jaech's non-constant-bias model were applied. Some of the results of the statistical analysis may seem inconsistent which is due to the following reasons. For the statistical evaluations isotope abundance data (weight percent) as well as nuclear concentration data (atoms/initial metal atoms) were subjected to different outlier criteria before being used for further statistical evaluations. None of the four data evaluation groups performed a complete statistical data analysis which would render possible a comparison of the different methods applied since no commonly agreed statistical evaluation procedure existed. The results prove that ICT is as accurate as conventional techniques which have to rely on costly mass spectrometric isotope dilution analysis. The potential of outlier detection by ICT on the basis of the results from a single laboratory is as good as outlier detection by costly interlaboratory comparison. The application of fission product or Cm-244 correlations would be more timely than remeasurements at safeguards laboratories

      The measurement of the patient experience is a global movement that has caught the attention of healthcare reformers. The use of patient experience data to ameliorate healthcare practice is promising, although standardization in what, where, how and whose experience is measured does not yet exist. To truly further the patient experience agenda, there needs to be adoption at the system, regional and local level to help promote, inspire and lead to sustainable change. Caregiver insight into the patient experience should be leveraged to learn what is important to patients and extract more useful data, as they are often present during transitions in care that span across the continuum. Embracing the voice of the patient as part of the process to improve quality, outcomes and experience will no doubt lead to impactful change and better care. © 2017 Longwoods Publishing.

      Some forest operations such as thinning and harvesting management could cause changes in N cycling and N2O emission from soils, since thinning and harvesting managements are accompanied with changes in aboveground environments such as an increase of slash falling and solar radiation on the forest floor. However, a considerable uncertainty exists in effects of thinning and harvesting on N2O fluxes regarding changes in belowground environments by cutting trees. To focus on the effect of changes in belowground environments on the N2O emissions from soils, we conducted a tree manipulation experiment in Japanese cedar (Cryptomeria japonica) stand without soil compaction and slash falling near the chambers and measured N2O flux at 50 cm and 150 cm distances from the tree trunk (stump) before and after cutting. We targeted 5 trees for the manipulation and established the measurement chambers to the 4 directions around each targeted tree relative to upper slope (upper, left, right, lower positions). We evaluated the effect of logging on the emission by using hierarchical Bayesian model. HB model can evaluate the variability in observed data and their uncertainties in the estimation with various probability distributions. Moreover, the HB model can easily accommodate the non-linear relationship among the N2O emissions and the environmental factors, and explicitly take non-independent data (nested structure of data) for the estimation into account by using random effects in the model. Our results showed tree cutting stimulated N2O emission from soils, and also that the increase of N2O flux depended on the distance from the trunk (stump): the increase of N2O flux at 50 cm from the trunk (stump) was greater than that of 150 cm from the trunk. The posterior simulation of the HB model indicated that the stimulation of N2O emission by tree cut- ting could reach up to 200 cm in our experimental plot. By tree cutting, the estimated N2O emission at 0-40 cm from the trunk doubled

      Full Text Available In November of 2010, the correspondences between US Foreign Office and US Embassies were leaked to the sensational web site, WikiLeaks and a little while after they begun to be published. This case, that w as named as the 11 th September of the diplomacy by Franco Frattini, who is the Italian foreign min ister, caused a shock as strong as 9/11 at least. It not only trigg ered off series of hard and important security precautions in short term, but a lso seems to change all diplomatic dynamics in mid and long term. The polit ical and international relations area is not the only domain on which this “cable-gate” had a significant impact; the global media (especially journalism is another area that has to be considered as reshaping after WikiLeaks. Many schol ars frequently argue that the new communication technologies and the exchanges th at WikiLeaks brought out in the area of media will evoke the end of the conv entional press. However, this study aims to argue a different point of view; that WikiLeaks experience has shown how the conventional press and new media tech nologies would co-operate. An activist named Julian Assange founds WikiLeaks – it’s rather to say hack- tivist - on December 3 rd , 2006 as a global act movement. In his first manif est (Authoritarian power is maintained by conspiracy A ssange identifies an open- government idea. According to this idea, government s all around the world must be open and non-despotic. To gain this open governm ent idea, the new communication technologies and the new media is ext remely important. But the new media is not enough itself, it also requires th e old conventional press, so the new media and conventional press have to co-operate to be more effective and powerful. While WikiLeaks was only depending on the power of global net at the beginning, especially after the big leaks in 2010, it seems that Assange and his web-phenomenon will collaborate tightly with conven tional press.

    1. Sleep paralysis as spiritual experience.

      Hufford, David J

      2005-03-01

      This article presents an overview of the sleep paralysis experience from both a cultural and a historical perspective. The robust, complex phenomenological pattern that represents the subjective experience of sleep paralysis is documented and illustrated. Examples are given showing that, for a majority of subjects, sleep paralysis is taken to be a kind of spiritual experience. This is, in part, because of the very common perception of a non-physical 'threatening presence' that is part of the event. Examples from various cultures, including mainstream contemporary America which has no widely known tradition about sleep paralysis, are used to show that the complex pattern and spiritual interpretation are not dependent on cultural models or prior learning. This is dramatically contrary to conventional explanations of apparently 'direct' spiritual experiences, explanations that are summed up as the 'Cultural Source Hypothesis.' This aspect of sleep paralysis was not recognized through most of the twentieth century. The article examines the way that conventional modern views of spiritual experience, combined with medical ideas that labeled 'direct' spiritual experiences as psychopathological, and mainstream religious views of such experiences as heretical if not pathological, suppressed the report and discussion of these experiences in modern society. These views have resulted in confusion in the scientific literature on sleep paralysis with regard to its prevalence and core features. The article also places sleep paralysis in the context of other 'direct' spiritual experiences and offers an 'Experiential Theory' of cross-culturally distributed spiritual experiences.

    2. Data analysis for electronic experiments

      1981-01-01

      In this lecture I schell attempt to cover the principal off-line software aspects in electronic experiments. Of course, this is too ambitious an undertaking for two reasons: Firstly the field is vast, and some important aspect will certainly have escaped my attention. Secondly, the choice of methods, features, algorithms, and packages presented will be biased through my personal opinion and experience, although to some extent it is influenced as well by the opinion and experience of my colleagues, who, like myself, are working in this field at CERN. Therefore, beware. Whenever I shall claim something to be evident, a matter of experience -- a fact --it ain't necessarily so. On the other hand, it will not be entirely wrong, since our experience is based on something like 30 experiments in high-energy physics using electronic for other people, and although these people are of course misled, one has to admit their existence.

      1988-09-01

      The availability of latex microspheres, compact television cameras and electronic calculators make it possible to perform an experiment on Brownian movement in one laboratory period. A more accurate value of N can be determined by other methods. However, the experiment described above has several valuable pedagogical outcomes. Undergraduate students get experience with several experimental techniques: (i) recording a `random walk' of a microphere; (ii) plotting a histogram of displacements; (iii) fitting a Gaussian curve to the histogram; (iv) checking the goodness of fit analytically or with probability graph paper; (v) calibrating screen displacements with a diffraction grating; (vi) calculating Avogadro's number from the experimental data; (vii) verifying data validity with the Einstein - Smoluchowski Law. The experiment also provides valuable practice in unit conversion and error analysis. Another instructive feature: the experiment makes the students aware of Einstein's work other than relativity. The students' reactions to the experiment were positive: `interesting', `challenging', `fun'.

      We review previous attempts to study mystical experience and point to problems inherent to certain methodologies. Focusing on studies that use controlled environments we advocate taking an experimental approach to mysticism. To demonstrate the viability of this approach, we report findings from...... a new study that probes the potential for eliciting mystical experiences in the laboratory. We find that our experimental paradigm is indeed enough to elicit mystical experiences. Based on subjective ratings of experience, rich descriptions from interviews, and data obtained three months after the study......, our data indicate that the experiences reported by the participants had a high degree of authenticity and had lasting effects in terms of memory and attribution. These findings demonstrate that at least some forms of mystical experience can be studied in a controlled environment. Prospects...

      2008-01-01

      In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC) experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG/EGEE, OSG, NDGF) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications

      Unlike the other large barrel-like experiments at the LHC, the LHCb detector consists of a series of large wall-like sub-detectors. The proton beams will collide at one end of the experiment hall and the detector will observe particles produced which travel close to the axis of the beam. This experiment will observe the production and subsequent decay of bottom quarks to look for rare 'CP violating' processes.

    10. Children's experiences of domestic violence

      OpenAIRE

      Callaghan, Jane

      2016-01-01

      This paper describes the key findings of a two year project focused on children's experiences of domestic violence. It draws on 107 interviews with children in Greece, Italy, Spain and the UK. The paper explores children's capacity to articulate their experiences, and highlights that they are not 'witnesses' to intimate partner violence, but experience it directly and make meaning of it, as members of a family affected by violence. I argue that children need to be recognised as direct victims...

      Kanzleiter, T.; Wolf, L.; Schoeck, W.

      1987-01-01

      In the DEMONA experiments the behavior of aerosols released into a large dry PWR containment during a core meltdown accident was investigated by means of a 640 m 3 model containment. After performance of eight experiments with quasi-single-compartment containment geometry and one multi-compartment experiment, the DEMONA project is being completed by evaluating and recalculating the measured results. Up to now, good agreement between experiment and model calculations was achieved only for simple test conditions. Adequate modeling of more complicated test conditions requires additional analytical efforts

    13. Heidegger, lived experience and method.

      2014-07-01

      A discussion of the assumption that Heidegger's philosophy in Being And Time provides a warrant for the study of lived experience. It is generally assumed, in nursing as in other disciplines, that Heidegger's philosophy points, uncontroversially, to the study of lived experience. It is also assumed that studies of this type will take the form of qualitative interviews which seek to explore the respondent's experience of a particular phenomenon and to elicit the meanings which the individual concerned attaches to that experience. Being And Time; the philosophical literature on Heidegger since 1999; the literature of experimental social psychology, 1970-2012. According to Heidegger, there is no such thing as 'lived experience'. The concept is embedded in the subject-object dualism that he is attempting to dismantle. In Heideggerian terms, interviews intended to explore 'lived experience' can only reproduce the voice of das Man, the 'They', not the voice of unique individuals. Methods more in keeping with Heidegger's philosophy include observation, naturalistic experiments, some forms of discourse analysis and conceptually associated lines of enquiry involving vocabularies of motive, scripts and the performative aspects of language use. Nursing researchers who wish to embrace Heidegger's philosophy as a basis for their work should abandon 'lived experience' interviews and adopt one of the alternative methods suggested above. Nursing researchers who wish to continue with 'lived experience' interviews should seek an alternative philosophical or theoretical basis for their work. © 2013 John Wiley & Sons Ltd.

    16. Quantitative nature of overexpression experiments

      Science.gov (United States)

      Moriya, Hisao

      2015-01-01

      Overexpression experiments are sometimes considered as qualitative experiments designed to identify novel proteins and study their function. However, in order to draw conclusions regarding protein overexpression through association analyses using large-scale biological data sets, we need to recognize the quantitative nature of overexpression experiments. Here I discuss the quantitative features of two different types of overexpression experiment: absolute and relative. I also introduce the four primary mechanisms involved in growth defects caused by protein overexpression: resource overload, stoichiometric imbalance, promiscuous interactions, and pathway modulation associated with the degree of overexpression.

      International Nuclear Information System (INIS)

      White, J.R.; Berta, V.T.; Holmstrom, H.L.O.

      1977-04-01

      A computer analysis, using the WHAM and RELAP4 computer codes, was performed to predict the LOFT system thermal-hydraulic response for Experiment L1-4 of the nonnuclear (isothermal) test series. Experiment L1-4 will simulate a 200 percent double-ended offset shear in the cold leg of a four-loop large pressurized water reactor. A core simulator will be used to provide a reactor vessel pressure drop representative of the LOFT nuclear core. Experiment L1-4 will be initiated with a nominal isothermal primary coolant temperature of 282.2 0 C, a pressurizer pressure of 15.51 MPa, and a primary coolant flow of 270.9 kg/s. In general, the predictions of saturated blowdown for Experiment Ll-4 are consistent with the expected system behavior, and predicted trends agree with results from Semiscale Test S-01-4A, which simulated the Ll-4 experiment conditions

      2008-10-24

      I learned a great deal during my summer internship at Lawrence Livermore National Laboratory (LLNL). I plan to continue a career in research, and I feel that my experience at LLNL has been formative. I was exposed to a new area of research, as part of the Single Particle Aerosol Mass Spectrometry (SPAMS) group, and I had the opportunity to work on projects that I would not have been able to work on anywhere else. The projects both involved the use of a novel mass spectrometer that was developed at LLNL, so I would not have been able to do this research at any other facility. The first project that Zachary and I worked on involved using SPAMS to detect pesticides. The ability to rapidly detect pesticides in a variety of matrices is applicable to many fields including public health, homeland security, and environmental protection. Real-time, or near real-time, detection of potentially harmful or toxic chemical agents can offer significant advantages in the protection of public health from accidental or intentional releases of harmful pesticides, and can help to monitor the environmental effects of controlled releases of pesticides for pest control purposes. The use of organophosphate neurotoxins by terrorists is a possibility that has been described; this is a legitimate threat, considering the ease of access, toxicity, and relatively low cost of these substances. Single Particle Aerosol Mass Spectrometry (SPAMS) has successfully been used to identify a wide array of chemical compounds, including drugs, high explosives, biological materials, and chemical warfare agent simulants. Much of this groundbreaking work was carried out by our group at LLNL. In our work, we had the chance to show that SPAMS fulfills a demonstrated need for a method of carrying out real-time pesticide detection with minimal sample preparation. We did this by using a single particle aerosol mass spectrometer to obtain spectra of five different pesticides. Pesticide samples were chosen to

      Dean, Angela; Draguljić, Danel

      2017-01-01

      This textbook takes a strategic approach to the broad-reaching subject of experimental design by identifying the objectives behind an experiment and teaching practical considerations that govern design and implementation, concepts that serve as the basis for the analytical techniques covered. Rather than a collection of miscellaneous approaches, chapters build on the planning, running, and analyzing of simple experiments in an approach that results from decades of teaching the subject. In most experiments, the procedures can be reproduced by readers, thus giving them a broad exposure to experiments that are simple enough to be followed through their entire course. Outlines of student and published experiments appear throughout the text and as exercises at the end of the chapters. The authors develop the theory of estimable functions and analysis of variance with detail, but at a mathematical level that is simultaneously approachable. Throughout the book, statistical aspects of analysis complement practical as...

    8. Aura, Self, and Aesthetic Experience

      Directory of Open Access Journals (Sweden)

      Marshall Battani

      2011-01-01

      Full Text Available Aesthetic experiences are generated in encounters with cultural objects and such experiences are marked by the free play of cognitive and numinous experience unstructured by concepts. Kant’s famous three types of pleasure, made infamous in social theory by Pierre Bourdieu, are examined in relation to the critical theoretical concept of aura, the social psychology of “flow,” and cognitive explanations of perception to explain experience in aesthetic fields. Theories of aesthetic experience developed at the crossroad of critical social thought and cognitive science hold promise for a social analysis able to avoid the usual sociological pitfalls of either ignoring aesthetics or reducing it to structurally determined differences of taste.

      In this work the nuclear fuel burn wave in a fast traveling wave reactor (TWR) is presented, using the reduced model of the neutron diffusion equation, considering only the axial component, and the equations of the transuranic dynamics of U-Pu and a radionuclide of Pu. Two critical zones of the reactor are considered, one enriched with U-Pu called ignition zone and the other impoverished zone or of U-238, named breeding zone. Occupying Na as refrigerant within TWR, and Fe as structural material; both are present in the ignition and breeding zones. Considering as a fissile material the Pu, since by neutron capture the U is transformed into Pu, thus increasing the quantity of Pu more than that of U; in this way the fuel burn stability with the wave dynamics is understood. The calculation of the results was approached numerically to determine the temporal space evolution of the neutron flux in this system and of the main isotopes involved in the burning process.

It was developed as a general simulation engine, as a tool devoted to the resolution of DAE's (ordinary differential and algebraic equations sets), doing abstraction of what physical system they represent. Component libraries must be added to the calculation engine, as needed by the discipline object of simulation, in order to be able of building up models. From first ECOSIM version there were already builded models applied to thermal and nuclear power plants. (Author)

      This document reproduces the final project of David San Fabian Ayuso, presented on May 26, 2005, for the obtention of the engineer degree of the Carlos III University of Madrid. A single-phase, isothermal model, including both electron and proton transport, is introduced for the simulation of polymer electrolyte fuel cells (PEM). The model is implemented in the commercial code Fluent 6.0, through the use of UDFs (User Defined Functions). In order to validate the model, a single canal of a PEM monocell is simulated in three dimensions. The obtained result are qualitatively satisfactory. It is observed that it is not essential to solve the current collectors when a monocell is considered (and not a stack). in the present study, the number of nodes is the computational grid appears to be too low in the membrane zone in order to make a complete validation of the model.

      In this paper the results of the simulation of the turbine discharge transient are shown, occurred in Unit 1 of nuclear power plant of Laguna Verde (NPP-L V), carried out with the model of this unit for the best estimate code Trace. The results obtained by the code Trace are compared with those obtained from the Process Information Integral System (PIIS) of the NPP-L V. The reactor pressure, level behavior in the down-comer, steam flow and flow rate through the recirculation circuits are compared. The results of the simulation for the operation power of 2027 MWt, show concordance with the system PIIS. (Author)

      Full Text Available Este artículo tiene como objetivo presentar una visión sobre las investigaciones que se han adelantado en los diferentes aspectos y aplicaciones de la Logística Inversa (LI, y aquellas herramientas y nuevos campos del conocimiento donde se puede aplicar LI. La revisión se llevó a cabo bajo tres temas de estudio: LI en empresas, Simulación de LI y Procesos de Recolección, Tratamiento y Disposición de Envases de Plaguicidas, este último viéndolo desde un concepto de recuperación o reciclaje de producto fuera de uso. La revisión se realiza a través del análisis de contenido de bibliografía publicada. Se hizo uso de varias bases de datos para la búsqueda de artículos de investigación relacionados con los temas bajo estudio, los cuales fueron clasificados de acuerdo al tema tratado. En la revisión bibliográfica se puede evidenciar que el 50% de la bibliografía consultada corresponde a LI aplicada o desarrollada en empresas, por medio de estudios tanto cualitativos como cuantitativos. Además, el 32% de los artículos revisados se enfoca en la simulación de LI, pero en la mayoría de casos no se utiliza como herramienta principal de investigación, sino como una herramienta de verificación y validación de la misma. Finalmente, las investigaciones actuales en cuanto a tratamiento y disposición de envases de plaguicidas carecen de los conceptos de LI como proceso. This article has as an objective to present a vision about the research made in the different aspects and applications of the inverse logistics (LI and the tools and new fields in which the LI knowledge may be applied. The review was conducted under three areas of study: Reverse Logistics (RL in companies, RL and Process Simulation, Collection, Treatment and Disposal of Pesticide Containers, the latter seeing it from a concept of recovery or recycling products out of use. The review is done through content analysis of published literature. Use was made of multiple databases to search for research articles related to the topics under study, which were classified according to the subject. In the literature review, it can be demonstrated that 50% of the consulted bibliography corresponds to the LI applied or developed in companies, through studies either qualitative and quantitative. Furthermore, 32% of the reviewed articles the focus of the research is based on the simulation of LI, but in most cases it is not used as a main tool in the research, but as a tool of verification and validation of it. Finally, the current research about treatment and final disposal of pesticides lack of the concepts of LI as a process.

      The study of nanoparticles coalescence and silver nano rods phenomena by means of molecular dynamics simulation under the thermodynamic laws is reported. In this work we focus ourselves to see the conditions under which the one can be given one dimension growth of silver nano rods for the coalescence phenomenon among two nano rods or one nano rod and one particle; what allows us to study those structural, dynamic and morphological properties of the silver nano rods to different thermodynamic conditions. The simulations are carried out using the Sutton-Chen potentials of interaction of many bodies that allow to obtain appropriate results with the real physical systems. (Author)

      The results concerning on an experimental and a numerical study related to SFRCP are presented. Eighteen pipes with an internal diameter of 600 mm and fibre dosages of 10, 20 and 40 kg/m3 were manufactured and tested. Some technological aspects were concluded. Likewise, a numerical parameterized model was implemented. With this model, the simulation of the resistant behaviour of SFRCP can be performed. In this sense, the results experimentally obtained were contrasted with those suggested by means MAP reaching very satisfactory correlations. Taking it into account, it could be said that the numerical model is a useful tool for the optimal design of the SFRCP fibre dosages, avoiding the need of the systematic employment of the test as an indirect design method. Consequently, the use of this model would reduce the overall cost of the pipes and would give fibres a boost as a solution for this structural typology. (Author) 27 refs.

      This is a databook of TRACY ''ramp feed'' experiments. TRACY is a reactor to perform supercritical experiments using low-enriched uranyl nitrate aqueous solution. The excess reactivity of TRACY is 3$ at maximum, and it is inserted by feeding the solution to a core tank or by withdrawing a control rod, which is called as the transient rod, from the core. In the ramp feed experiment, the supercritical experiment is initiated by feeding the fuel solution to the core tank in a constant feed rate. The data in the present databook consist of datasheets and graphs. Experimental conditions and typical values of measured parameters are tabulated in the datasheet. In the graph, power and temperature profiles are plotted. Those data are useful for the investigation of criticality accidents with fissile solutions, and for validation of criticality accident analysis codes. (author)
