    Full Text Available The dental wastewater can contribute to the total daily mercury load on environment. Factorial design of experiments is useful toanalysis of factors that influence in this mobility. The aim of the present study was to design experiments to examine the effects ofoperational variables – temperature, pH and contact time - which may affect the mobility of mercury in form of dental amalgamresidue in reduction process in the sediments of the Pirapó River. Based on the factorial design of experiments and the analysis ofvariance, the temperature was the most significant factor in this process, followed by the pH and contact time. The parametersaffecting the mobility of total mercury showed that when the temperature and contact time increases and pH decreases there is animportant increase of mercury concentration in process. For the tested conditions, the high total mercury concentration was obtainedusing the temperature = 35oC, pH = 4.0 and contact time = 10 days.

    An expert system for the failure analysis in metallic mechanical devices is being Developer at the Mechanical Engineering departments of the Faculty of Engineering of the Universidad Nacional Autonoma de Mexico (UNAM) to provide a solution for the failure analysis in cases where considerable experience in needed. The system pretends to resolve the scarceness of experts in the field of failure analysis and is oriented toward the metal-mechanics industry and will also have didactic applications. The main complication in the development of the system is the broad range of applications envisioned, like gears, shafts, bolts and springs between others. Therefore, it was decided to develop the system in a modular way, using the experience obtained in a first module to proceed faster in the others. The present paper presents the elaboration of the module that analyses shafts. This will serve as the base to expand the system toward other components. It uses the general structure of the global system, including an auxiliary software for the determination of maximum stresses in the corresponding parts.

    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.

    Full Text Available La mortalidad es uno de los componentes de la dinámica demográfica constituido en un importante indicador del reflejo del estado de salud de una población, por lo que conocer su comportamiento es de suma importancia en el desarrollo de las sociedades. El objetivo de la presente investigación es construir un modelo de análisis factorial mediante la aplicación de la técnica de componentes principales a un conjunto de tasas de mortalidad por grupo de edad y sexo para identificar componentes influyentes en la mortalidad de Costa Rica durante el período 1900-2010. El análisis factorial permitió identificar inicialmente tres factores principales que explican en un 96,6 % la variabilidad de la mortalidad de Costa Rica. Se espera que esta serie de estimaciones contribuyan al estudio del comportamiento de la mortalidad y de sus implicaciones para el desarrollo del país y, a su vez, sirva de base para que futuros estudios complementen los alcances de la presente investigación.

    Full Text Available La coyuntura laboral reciente del desempleo en Colombia muestra que su componente cíclico se ha reducido a su mínima expresión y que, por ende, la mayor parte del desempleo actual hace referencia a las tipologías friccional y estructural del desempleo, y puede ser explicado en gran parte por el “mismatch” existente entre la demanda y la oferta de trabajo. La carencia de información sobre las necesidades y requerimientos del sector productivo ahondan y mantiene, aún más, las brechas existentes entre ambos componentes del mercado laboral. Dada esta situación, este trabajo propone una solución a la falta de información sobre los requerimientos cuantitativos y cualitativos de la demanda de trabajo, desde una metodología de big data, es decir, la aglomeración y sistematización de grandes cantidades de información, teniendo como fuente de información la utilizada por las bolsas de empleo colombianas en sus actividades de colocación. Procesada esta información, y luego comparada con la información de oferta laboral disponible en encuestas de hogares, puede concluirse que una base de vacantes construida a partir de big data en Colombia, es una excelente herramienta para conocer la demanda que, por distintas habilidades, tiene el sector productivo y, por ende, la formulación de políticas públicas integrales de educación y formación, sumamente requeridas en el país. Este artículo documenta el esfuerzo pionero desarrollado al respecto.

    In this paper the development of a computer tool for the analysis of centrifugal pumps is presented. This tool allows the user to analyze the performance of the pump by means of the analysis of the behavior curves at its design conditions, reference and operation. In order to realize the analysis it is necessary that the user feeds the tool with the missing and necessary information according to norm ASME PTC 8.2 and under the specified conditions of calibration of the same norm, to eliminate possible errors in the results, a bad qualification or erroneous acquisition of the signals. The system must early be fed with the polynomials of the behavior curves of the pump in its design conditions to later correct the behavior based on a velocity of present operation. [Spanish] En este trabajo se presenta el desarrollo de una herramienta computacional para el analisis de bombas centrifugas. Dicha herramienta permite al usuario analizar el desempeno de la bomba mediante el analisis de las curvas de comportamiento en sus condiciones de diseno, referencia y operacion.

    A new method to assess the performance of a solar dryer is presented. It describes energy efficiency indicators to improve a commercial dryer design. First, a preliminary dryer design procedure is described step by step. Then, two different modes of a tunnel dryer are investigated: Batch and semi-continue operations. The results of the analysis show that, the thermal efficiency is not sufficient to rate de dryer performance. It is necessary to include the productivity of the drying process and the quality of the dried fruit. The drying process and productivity tend to go hand-in-hand but in opposite directions. That is to say, raising the thermal efficiency reduce the process productivity and conversely. The analysis also suggests that an agreement between the efficiency, productivity and the quality must be specified in the drier design. [Spanish] Se presenta un procedimiento nuevo para evaluar la operacion de un secador solar, con el cual se precisan indicadores de la eficiencia que pueden ser utiles para mejorar el diseno del equipo. Se empieza por describir los pasos de un procedimiento de diseno preliminar de un sistema de secado. Despues, se analizan cualitativamente dos secadores: uno que opera por lotes y el otro de modo semicontinuo. Los resultados del analisis muestran que, la eficiencia termica del equipo no es un criterio suficiente para evaluar su operacion; tambien se requiere tomar encuenta la productividad del proceso de secado y la calidad del producto final. Se concluye que la eficiencia termica y la productividad del proceso son conceptos encontrados. Es decir, la eficiencia termica del equipo no es un criterio suficiente para evaluar su operacion; tambien se requiere tomar en cuenta la productividad del proceso de secado y la calidad del producto final. Se concluye que la eficiencia termica y la productividad del proceso son conceptos encontrados. Es decir, la eficiencia termica solo se puede aumentar a costa de la productividad y viceversa

[Spanish] En este trabajo se presenta un analisis en tres enfoques: teorico, numerico y experimental, del comportamiento dinamico y de la estabilidad vibratoria de un sistema rotor chumacera conteniendo una grieta transversal localizada a medio tramo de la longitud axial del eje. La presencia de una grieta transversal es considerada mediante la modelacion de la variacion periodica de la rigidez estructural del rotor, la cual se expresa en funcion del tiempo (o posicion angular). El amortiguamiento del sistema incluye un amortiguamiento externo debido al fluido dentro del cual se encuentra el rotor girando y, el mas significativamente, un amortiguamiento viscoso originado por la pelicula de aceite en las chumaceras. El problema en estudio consiste en un rotor extendido del tipo Jeffcott, el cual tiene un disco al centro y chumaceras hidrodinamicas identicas en los dos extremos. Un aspecto innovador que aumenta la complejidad del analisis es que se incluye el efecto que tiene la masa del eje en cada una de las chumaceras en los extremos, ademas del efecto obvio de la masa del disco. Se hace una analisis numerico de la estabilidad lineal del sistema incluyendo todos los aspectos mencionados mediante la teoria de Floquet. Algunos resultados son comparados con los obtenidos por otros investigadores en este campo como Gasch, Meng y otros. El sistema parametricamente excitado resultante es analizado utilizado una solucion de perturbacion lineal del sistema. El sistema de ecuaciones se encuentra utilizando terminos complejos y ha sido representado y escrito en programas de computo en MATLAB desarrollados por el autor de la tesis para calcular la estabilidad lineal del problema. Varias configuraciones de rotores simples y reales son estudiados con el fin de ilustrar las propiedades basicas de rotores

    Often, the rotary equipment faults appear as an abnormal vibration or a change in the characteristic vibration pattern of each machine. From here the importance of counting on tools that allow to acquire and to analyze the vibration signals of the equipment while it is in operation. The Gerencia de Turbomaquinaria has worked in this field since the end of the Seventies, developing diagnosis systems based on personal computers that allow the monitoring of the dynamic behavior of the rotary equipment. The main system of this type that the Instituto de Investigaciones Electricas (IIE), nowadays offers, is the Computerized System for Dynamic Analysis, also known by its abbreviation in Spanish as: SICAD II. This was designed under the requirements of the Comision Federal de Electricidad (CFE) to collect, measure and analyze vibration data of rotary equipment. It is also used in the balance, fault diagnosis and the solution of problems in rotary equipment. The system SICAD II is portable and versatile system with which vibrations are acquired, measured and analyzed by means of the presentation of the data in graphical formats of different type and application. [Spanish] A menudo, las fallas en los equipos rotatorios se manifiestan como una vibracion anormal o como un cambio en el patron de vibraciones caracteristico de cada maquina. De ahi la importancia de contar con herramientas que permitan adquirir y analizar las senales de vibracion de los equipos mientras estan en operacion. La Gerencia de Turbomaquinaria ha trabajado en este campo desde finales de la decada de los setenta, desarrollando sistemas de diagnostico basados en computadoras personales que permiten monitorear el comportamiento dinamico de los equipos rotatorios. El principal sistema de este tipo que ofrece, actualmente, el Instituto de Investigaciones Electricas (IIE) es el Sistema Computarizado para Analisis Dinamico, conocido tambien por su abreviacion como: Sicad II.

    The usage of hydrocarbons, such as natural gas, oil products and coal, will be the main source of energy to the mankind for next generations. Therefore, the actual research and technological developments point out to employ with high efficiency those fuels. The main interests are to release most of the energy as possible and to guide the combustion reactions. It is well known that during the combustion process of coal, the chemical energy is converted to thermal energy, which it allows the steam production, and therefore to produce energy through an electric generator. The main interest of the work presented here is to study the behavior of the coal combustion processes in function of the approximate analysis and some associate indices of that analysis, to point out the optimization of the coal usage as main fuel in electrical power generation plants. [Spanish] El uso de hidrocarburos como son el gas natural, los derivados del petroleo y el carbon mineral, continuara siendo en las proximas decadas la principal fuente de energia de la humanidad. Por consiguiente, la investigacion cientifica y los desarrollos tecnologicos actualmente se enfocan en emplear de manera mas eficiente dichos combustibles, satisfaciendo entre otros factores, dos intereses principales: liberar la mayor cantidad de energia, reduciendo al minimo el material combustible no quemado, y direccionar las reacciones del proceso de combustion para minimizar la cantidad de productos no deseados resultantes de la reaccion. A traves de los procesos quimicos de combustion del carbon, se transforma la energia quimica a energia termica, lo que permite la produccion de vapor para a su vez impulsar una turbina la cual esta acoplada a un generador electrico. El objetivo del presente trabajo es el estudio del comportamiento de los procesos quimicos que se llevan a cabo durante las reacciones de combus-tion del carbon en funcion del analisis aproximado y de los indices asociados resultantes de dicho analisis; lo

    The dimensionless model developed and validated by Baritto and Bracamonte (2012) for the thermal behavior of flat plate solar collector without glass cover is improved by adding the entropy balance equation in a dimensionless form. The model is solved for a wide range of aspect ratios and mass flow numbers. A parametric study is developed and the distribution of internal irreversibilities along the collector is analyzed. The influence of the design parameters on the entropy generation by fluid friction and heat transfer is analyzed and it is found that for certain combinations of these parameters optimal thermodynamic operation can be achieved. [Spanish] En el presente trabajo, el modelo adimensional desarrollado y validado por Baritto y Bracamonte (2012) para describir el comportamiento termico de colectores solares de placas planas sin cubierta transparente, se complementa con la ecuacion adimensional de balance de entropia para un elemento diferencial de colector solar. El modelo se resuelve para un amplio rango de valores de relaciones de aspecto y numero de flujo de masa. A partir de los resultados del modelo se desarrolla un analisis detallado de la influencia de estos parametros sobre la distribucion de irreversibilidades internas a lo largo del colector. Adicionalmente se estudia la influencia de estos parametros sobre los numeros de generacion de entropia por friccion viscosa, por transferencia de calor y total. Se encuentra que existen combinaciones de los parametros antes mencionados, para los cuales, la operacion del colector es termodinamicamente optima para numeros de flujo de masa elevados.

    El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida.

    This paper presents the analysis of the tools commonly utilized in Bioclimatic Design, for the achievement of humidity an temperature comfort conditions in architectonic spaces. The analysis was performed by means of field studies and experimentally for different sport activities, carried out in spaces designed for each purpose. In the experimental part, inside ambient temperature and relative humidity were measured in the different spaces where sport activities were conducted, such as calisthenics, dance, judo, wrestling, weight lifting, boxing, basket-ball, volley-ball, gymnastics and fencing. At the same time an inquiry was conducted among their occupants in respect to the thermal sensation they experimented while conducting such activities. The results obtained in the inquiry were compared with the results reported by other researchers, by means of tables and psychometric diagrams as optimum values for temperature comfort. As a conclusion it was decided that the graphic and mathematical methods analyzed, are based on a sedentary activity, therefore in using them for the design of spaces for different activities uncomfortable conditions are experimented with the consequential necessity of air conditioning, which implies energy consumption and the corresponding expenditure, lastly it is necessary to adapt these tools, that is, consider the activity that is going to be performed in the buildings.

    The properties of the neutrino provide a unique window on physics beyond that described by the standard model. The study of subleading effects in neutrino oscillations, and the race to discover CP-invariance violation in the lepton sector, has begun with the recent discovery that $\\theta_{13} > 0$. The measured value of $\\theta_{13}$ is large, emphasizing the need for a facility at which the systematic uncertainties can be reduced to the percent level. The neutrino factory, in which intense neutrino beams are produced from the decay of muons, has been shown to outperform all realistic alternatives and to be capable of making measurements of the requisite precision. Its unique discovery potential arises from the fact that only at the neutrino factory is it practical to produce high-energy electron (anti)neutrino beams of the required intensity. This paper presents the conceptual design of the neutrino factory accelerator facility developed by the European Commission Framework Programme 7 EURO$\

    The discovery of neutrino oscillations marks a major milestone in the history of neutrino physics, and opens a window to what lies beyond the Standard Model. Many current and forthcoming experiments will answer open questions; however, a major step forward, up to and possibly including CP violation in the neutrino mixing matrix, will be offered by the neutrino beams from a neutrino factory. The neutrino factory is a new concept for producing neutrino beams of unprecedented quality in terms of intensity, flavour composition, and precision of the beam parameters. These beams enable the exploration of otherwise inaccessible domains in neutrino oscillation physics by exploiting baselines of planetary dimensions. Suitable detectors pose formidable challenges but seem within reach with only moderate extrapolations from existing technologies. Although the main physics attraction of the neutrino factory is in the area of neutrino oscillations, an interesting spectrum of further opportunities ranging from high-precisi...

    The electricity industry traditionally had two thermodynamic cycles for power generation: conventional steam turbine (Rankine cycle) used to supply a base load during the day, and gas turbines (Brayton cycle), for its speed response, normally used to cover peak loads. However, to provide variable peak loads, the gas turbine, as a volumetric machine is affected by the change in air density by changing the combustion temperature. This paper shows the scheme of integration of both systems, that it's known as combined cycle and the different options that would have these power plants, to maintain or increase their power in variable ambient conditions. It analyzes different options, such as: 1. Supplementary fire in the stove. 2. Air cooling intake in the gas turbine (evaporation system or mechanical system). 3. Steam injection in the combustion chamber. [Spanish] La industria electrica tradicionalmente a contado con dos ciclos termodinamicos para generacion electrica: las turbinas convencionales de vapor (ciclo de Rankine) se utilizan para suministrar una carga base durante el dia, y las turbinas de gas (ciclo de Brayton), por su rapidez de respuesta, se utilizan normalmente para cubrir las cargas pico. Sin embargo, para suministrar las cargas variables pico, la turbina a gas, por ser una maquina volumetrica, se ve afectada por el cambio de la densidad del aire de combustion al cambiar la temperatura ambiente. En este trabajo se muestra el esquema de integracion de ambos sistemas, en lo que se conoce como ciclo combinado y las diferentes opciones que tendrian estas plantas de generacion electrica para mantener o incrementar su potencia en condiciones ambiente variable. Para ello se analizan diferentes opciones, tales como: 1.- Combustion suplementaria en el recuperador de calor. 2.- Enfriamiento del aire de admision a la turbina de gas (mediante un sistema de evaporacion o mediante un sistema mecanico). 3.- Inyeccion de vapor a la camara de combustion.

    A methodology to carry out Reliability Centered Maintenance (RCM) studies for hydroelectric power plants is presented. The methodology is an implantation/extension of the guidelines proposed by the Engineering Society for Advanced Mobility Land, Sea and Space in the SAE-JA1012 standard. With the purpose of answering the first five questions, that are set out in that standard, the use of standard ISO14224 is strongly recommended. This approach standardizes failure mechanisms and homogenizes RCM studies with the process of collecting failure and maintenance data. The use of risk matrixes to rank the importance of each failure based on a risk criteria is also proposed. [Spanish] Se presenta una metodologia para realizar estudios de mantenimiento Basado en Confiabilidad (RCM) aplicados a la industria hidroelectrica. La metodologia es una implantacion/ extension realizada por los autores de este trabajo, de los lineamientos propuestos por la Engineering Society for Advanced Mobility Land, Sea and Space en el estandar SAE-JA1012. Para contestar las primeras cinco preguntas del estandar se propone tomar como base los modos y mecanismos de fallas de componentes documentados en la guia para recopilar datos de falla en el estandar ISO-14224. Este enfoque permite estandarizar la descripcion de mecanismos de fallas de los equipos, tanto en el estudio RCM como en el proceso de recopilacion de datos de falla y de mantenimiento, lo que permite retroalimentar el ciclo de mejora continua de los procesos RCM. Tambien se propone el uso de matrices de riesgo para jerarquizar la importancia de los mecanismos de falla con base en el nivel de riesgo.

    Inflow performance relationships developed for petroleum and geothermal reservoirs are presented. Four of them were selected to be used in this work. Such relationships were developed considering features of a typical geothermal system. The performance of the selected relationships was assessed using data from production tests in several wells of different fields. A methodology is presented to determine the value of the maximum flow (W{sub max}) from the inflow relationships; its application is demonstrated using the data of the 10 production tests. It was found that the calculated value of W{sub max} under stabilization conditions may be related to the reservoir response. In general, there is a good agreement between the calculated values of W{sub max} from the different methods. The differences in the W{sub max} values vary within 10%. It was found that the stability in the calculated values of W{sub max} as a response of the reservoir is a function of the flow magnitude. So, the wells with flow greater than 200 t/h reach the stability of W{sub max} at openings 50% less of their total capacity.

    chapter is an historical sketch of the harmonic sources in power systems, as well as the problems that the presence of these cause. For the good performance of the work, its importance must be specified, to have the required data available and to carry out the necessary considerations to simplify the study without including significant errors. These requirements comprise part of chapter two. Chapter three deals, in a summarized way, with the analysis tools and the Standards, as well as with some important considerations with respect to the measurements. In chapter four the models of some electric elements, linear as well as nonlinear are presented. The presence of the capacitors to correct the power factor can originate resonance effects under different schemes of harmonic injection. For this reason, the purpose of chapter five is the specification of the scheme that represents the most severe resonance condition. Chapter six describes the electric arc model, as well as the way the necessary conditions were carried out to approximate the proposed model. Later, chapter seven includes the validation of the electric arc model and emphasizes the importance that the simulation of transients due to maneuvers in the system has. Finally, chapter eight contains the conclusions generated as a result of the research work, as well as the recommendations for future works in the area. [Spanish] La presencia de armonicas es un problema que ha existido durante muchos anos en los sistemas de potencia. Sin embargo, en la epoca actual el aumento en las cargas generadoras de armonicas se ha incrementado considerablemente como respuesta al desarrollo de la industria y de los satisfactores que reclama la vida moderna. Para llevar a cabo este trabajo de investigacion se considera la red electrica de una planta industrial destinada a la produccion de acero, la cual cuenta con tres hornos electricos en arco.

    Tortora, Cristina; Summa, Mireille Gettler

    2011-01-01

    Factorial clustering methods have been developed in recent years thanks to the improving of computational power. These methods perform a linear transformation of data and a clustering on transformed data optimizing a common criterion. Factorial PD-clustering is based on Probabilistic Distance clustering (PD-clustering). PD-clustering is an iterative, distribution free, probabilistic, clustering method. Factorial PD-clustering make a linear transformation of original variables into a reduced number of orthogonal ones using a common criterion with PD-Clustering. It is demonstrated that Tucker 3 decomposition allows to obtain this transformation. Factorial PD-clustering makes alternatively a Tucker 3 decomposition and a PD-clustering on transformed data until convergence. This method could significantly improve the algorithm performance and allows to work with large dataset, to improve the stability and the robustness of the method.

    In this paper, we will first indicate the key issues in designing a B-factory and a φ-factory, and illustrate the approaches that are being followed to address them. In general, reaching the B-factory parameter regime offers the most challenges, so we will emphasize it here. Then we will consider an extrapolation of our present understanding of collider performance and assess the maximum luminosity that could be anticipated. To reach extremely high luminosity, it may be necessary to consider possibilities beyond the scope of ''standard'' approaches to collider design; a few illustrative examples are outlined. For both the present designs and the extrapolated parameters, R ampersand D activities in a few key areas are required; these areas are discussed in this paper also

  15. The Super Flavor Factory

    Bevan, A.J.; /Queen Mary, U. of London

    2007-01-26

    The main physics goals of a high luminosity e{sup +}e{sup -} flavor factory are discussed, including the possibilities to perform detailed studies of the CKM mechanism of quark mixing, and constrain virtual Higgs and Non-Standard Model particle contributions to the dynamics of rare B{sub u,d,s} decays. The large samples of D mesons and {tau} leptons produced at a flavor factory will result in improved sensitivities on D mixing and lepton flavor violation searches, respectively. One can also test fundamental concepts such as lepton universality to much greater precision than existing constraints and improve the precision on tests of CPT from B meson decays. Recent developments in accelerator physics have demonstrated the feasibility to build an accelerator that can achieve luminosities of {Omicron}(10{sup 36} cm{sup -2} s{sup -1}).

    Full Text Available Levan is a non-toxic, biologically active, extra cellular polysaccharide composed solely by fructose units. Optimization of levan production by Zymomonas mobilis strain ZAG-12 employing a 2(4-1 fractional factorial design was performed to analyze the influence of the temperature (20, 25 e 30ºC agitation (50, 75 e 100 rpm, and the initial concentrations of both sucrose (150, 200 e 250 g.L-1 and yeast extract (2.0, 3.5 e 5.0g.L-1 on final levan concentration. Aerobic fermentation was performed batchwise in 500mL Pyrex flasks for 72 hours. Biomass, ethanol, levan and sucrose were determined at beginning and also at end of the fermentations. The experiments showed that the final levan concentration depended on initial sucrose concentration, temperature and agitation velocity and that the initial concentration of yeast extract did not influence levan production. However, when the production of ethanol and biomass were considered, it became evident that yeast extract was a significant variable. The best conditions for levan production occurred at 100 rpm agitation, 20ºC and 250g.L-1 of initial sucrose resulting in 14.67g.L-1 of levan.Levana é um polissacarídeo extracelular, biologicamente ativo, não tóxico, contendo em sua estrutura apenas frutose.

    A language is factorial if it is closed under taking factors (i.e. contiguous subwords). Every factorial language can be described by an antidictionary, i.e. a minimal set of forbidden factors. We show that the problem of deciding whether a factorial language given by a finite antidictionary is well-quasi-ordered under the factor containment relation can be solved in polynomial time. © 2013 Springer-Verlag Berlin Heidelberg.

    Full Text Available EST-SSR markers were used to investigate the genetic diversity among and within coffee populations, to explore the possibility of their use for fingerprinting of cultivars and to assist breeding programs. Seventeen markers, developed from ESTs (Expressed Sequence Tags from the Brazilian Coffee Genome Project, were used. All markers showed polymorphism among the genotypes assessed. The average number of allele per primer was 5.1. The highest polymorphisms were found within C. canephora (88.2% and rust-resistant varieties (35.3%. About 29.4% of the markers differentiated C. arabica from Híbrido de Timor; it was also possible to identify those closest and farthest from C. arabica . The analysis of population-grouped genotypes revealed a 64.0% genetic diversity among and a 36.0% genetic diversity within populations. The differentiation index was 0.637. Six markers distinguished four rust-resistance varieties, showing their fingerprinting potential. These results demonstrate the usefulness of EST-SSR markers for cross orientation, in diversity and introgression studies, and in genetic mapping.No estudo da diversidade genética entre e dentro de populações de café, foram usados marcadores EST-SSR, visando avaliar seu potencial para identificar cultivares comerciais e assistir programas de melhoramento.

    The ATLAS experiment at the CERN LHC is one of the largest users of grid computing infrastructure, which is a central part of the experiment's computing operations. Considerable efforts have been made to use grid technology in the most efficient and effective way, including the use of a pilot job based workload management framework. In this model the experiment submits ‘pilot’ jobs to sites without payload. When these jobs begin to run they contact a central service to pick-up a real payload to execute. The first generation of pilot factories were usually specific to a single Virtual Organization (VO), and were bound to the particular architecture of that VO's distributed processing. A second generation provides factories which are more flexible, not tied to any particular VO, and provide new and improved features such as monitoring, logging, profiling, etc. In this paper we describe this key part of the ATLAS pilot architecture, a second generation pilot factory, AutoPyFactory. AutoPyFactory has a modular design and is highly configurable. It is able to send different types of pilots to sites and exploit different submission mechanisms and queue characteristics. It is tightly integrated with the PanDA job submission framework, coupling pilot flow to the amount of work the site has to run. It gathers information from many sources in order to correctly configure itself for a site and its decision logic can easily be updated. Integrated into AutoPyFactory is a flexible system for delivering both generic and specific job wrappers which can perform many useful actions before starting to run end-user scientific applications, e.g., validation of the middleware, node profiling and diagnostics, and monitoring. AutoPyFactory also has a robust monitoring system that has been invaluable in establishing a reliable pilot factory service for ATLAS.

    2012-01-01

    The ATLAS experiment at the CERN LHC is one of the largest users of grid computing infrastructure, which is a central part of the experiment’s computing operations. Considerable efforts have been made to use grid technology in the most efficient and effective way, including the use of a pilot job based workload management framework. In this model the experiment submits ’pilot’ jobs to sites without payload. When these jobs begin to run they contact a central service to retrieve a real payload to execute. The first generation of pilot factories were usually specific to a single VO, and were bound to the particular architecture of that VO’s distributed processing. A second generation provides factories which are more flexible, not tied to any particular VO, and provide new or improved features such as monitoring, logging, profiling, etc. In this paper we describe this key part of the ATLAS pilot architecture, a second generation pilot factory, AutoPyFactory. AutoPyFactory has a modular design and is hig...

  4. HIGHER LUMINOSITY B-FACTORIES

    International Nuclear Information System (INIS)

    The present B-factories PEP-II and KEKB have reached luminosities of 3-4 x 1033/cm2/s and delivered integrated luminosity at rates in excess of 4fb-1 per month [1,2]. The recent turn on of these two B-Factories has shown that modern accelerator physics, design, and engineering can produce colliders that rapidly reach their design luminosities and deliver integrated luminosities capable of frontier particle physics discoveries. PEP-II and KEK-B with ongoing upgrade programs should reach luminosities of over 1034/cm2/s in a few years and with more aggressive improvements may reach luminosities of order 1035/cm2/s by the end of the decade. However, due to particle physics requirements, the next generation B-Factory may require significantly more luminosity. Initial parameters of a very high luminosity e+e- B-Factory or Super B-Factory (SBF) are being developed incorporating several new ideas from the successful operation of the present generation e+e-accelerators [3,4]. A luminosity approaching 1036 cm-2s-1 appears possible. Furthermore, the ratio of average to peak luminosity may be increased by 30% due to continuous injection. The operation of this accelerator will be qualitatively different from present e+e- colliders due to this continuous injection

    The presence of electromechanical oscillations in any electrical power system is a typical characteristic of this kind of systems. Provided the damping associated with these oscillations lies above of a minimum specified value, the occurrence of these oscillations is not considered as a threat to the system operation. This paper focuses the attention on the application of modal analysis for assessing the dynamical behavior of a power system subjected to small disturbances for different operating conditions and transmission system topologies, as well. The reported results indicate, that modal analysis enables a straight identification of the causes that contribute negatively to the damping of the electromechanical modes. [Spanish] La presencia de oscilaciones electromecanicas en cualquier Sistema Electrico de Potencia (SEP) es una caracteristica propia de estos sistemas. Mientras el amortiguamiento asociado con este tipo de oscilaciones se encuentre dentro de los limites considerados como aceptables para la operacion continua de este tipo de sistemas, el surgimiento de estas no se considera una amenaza para la operacion segura del SEP. El presente articulo, centra su atencion en la aplicacion del analisis modal para evaluar el comportamiento dinamico de un SEP ante la ocurrencia de disturbios de magnitud pequena para diferentes topologias y condiciones de operacion. Los resultados reportados indican, que la aplicacion del analisis modal permite la identificacion directa de las causas que contribuyen en forma negativa al amortiguamiento asociado con los modos electromecanicos, asi como la ubicacion mas adecuada de controles que contribuyan a mejorar el amortiguamiento de los mismos.

    Photon Factory Activity Report no.12 deals with our activities in the period from October 1993 through September 1994. We operate two light sources at the Photon Factory; the 2.5-GeV Photon Factory storage ring, which is a dedicated light source, and the 6.5-GeV TRISTAN Accumulation Ring, which is parasitically used as a light source. We keep more than seventy experimental stations at two facilities, and accept experiments primarily according to approval by the Program Advisory Committee. The number of proposals to the Photon Factory has been still growing. Three-hundred eighty two proposals were approved by the PAC in FY1994, which is an increase by thirteen percent compared to the previous year. Remarkable was growth in biology proposals, particularly proposals in protein crystallography. In FY 1994, we accepted approximately 20,000 man-days as general users, and almost ten percent of them were from abroad. We always open the facility to users, not only domestic but also international. Recently we have been concentrating our effort to upgrading of the light sources and reconstruction of the experimental stations to keep the Photon Factory an attractive research facility in the forthcoming years. We have already started a program of reducing the emittance of the 2.5-GeV storage ring, which now operates with an emittance of 110 nm-rad, to 27 nm-rad by modifying the lattice, with the goal of operation at the reduced emittance in the fall of 1997. We also have conceived of a conversion of the TRISTAN Accumulation Ring to a dedicated light source of high energies. The on-going TRISTAN project will terminate by the end of 1995, and the TRISTAN Main Ring will be converted to a new B-Factory. At this moment, the TRISTAN Accumulation Ring will be disused as the injector to the Main Ring, and conversion of the AR to a dedicated light source becomes possible. (J.P.N.)

    The RARF proposes `RIKEN RI Beam Factory` as a next facility-expanding project. The factory makes it the primary aim to provide RI (Radioactive Isotope) beams covering over the whole atomic-mass range with the world-highest intensity in a wide energy range up to several hundreds MeV/nucleon. These RI beams are generated by the fragmentation of high-intensity heavy-ion beams. For the efficient production heavy-ion energies will be boosted up to over 100 MeV/nucleon even for very heavy ions by a K2500-MeV superconducting ring cyclotron serving as a post accelerator of the existing K540-MeV ring cyclotron. A new type of experimental installation called `MUSES` (Multi-USe Experimental Storage rings) will be constructed as well. With MUSES, various types of unique colliding experiments will become possible. (author)

    These proceedings are based on lectures given at the Helmholtz International Summer School Heavy Quark Physics at the Bogoliubov Laboratory of Theoretical Physics, Dubna, Russia, during August 2008. I review the current status of CP violation in B meson decays from the B factories. These results can be used, along with measurements of the sides of the Unitarity Triangle, to test the CKM mechanism. In addition I discuss experimental studies of B decays to final states with 'spin-one' particles.

    Traditionally the specific consumption of energy has been considered as the most adequate index to evaluate the efficiencies in the productive processes. Nevertheless, this index, in some instances is highly susceptible to suffer significant variations, due to factors such as equipment condition, raw materials quality, operational parameters, climate and production level. This last one definitely is the most important and requires a deeper analysis. In this presentation a methodology is developed to analyze the energy consumption as well as their specific energy consumption with respect to production. Enough historical data are utilized to allow for a statistical analysis. This study is of equal usefulness in an energy diagnosis, as in a management program of energy saving. In presenting the possibility of identifying potential energy saving, stands out the advantages of the analysis and the conclusions that can be derived from it. Through the actual data collected in several industries during the energy diagnosis, various possible results of the analysis are presented. Finally, how this type of analysis can be adapted to a more precise control of the energy consumption is described and be used as a base for establishing goals in energy efficiency in the long term. [Espanol] Tradicionalmente se ha considerado al consumo especifico de energia como el indice energetico mas adecuado para evaluar las eficiencias de los procesos productivos.

    The gas turbines operate at extremely high temperatures, at high thermal and mechanical stresses, causing that the useful life of the involved components be reduced. In the present article the results realized by previous investigations of temperatures obtained from analysis of heat transfer and flow of fluids of the nozzle by means of the Star-CD program based on finite volumes is presented. Later, the NISA program of finite elements was used to realize the analysis of thermal stresses considering the material plasticity. The methodology employed to determine the material properties variable with the temperature of the super-alloy FSX-414 and the plasticity model used in the structural analysis in the finite element program. The result will be later used in the fatigue analysis for the useful life assessment.

    Muon colliders and neutrino factories are attractive options for future facilities aimed at achieving the highest lepton-antilepton collision energies and precision measurements of Higgs boson and neutrino mixing matrix parameters. The facility performance and cost depend on how well a beam of muons can be cooled. Recent progress in muon cooling design studies and prototype tests nourishes the hope that such facilities could be built starting in the coming decade. The status of the key technologies and their various demonstration experiments is summarized. Prospects "post-P5" are also discussed.

    Naturalness arguments applied to supersymmetric theories imply a spectrum containing four light higgsinos \\tz_{1,2} and \\tw_1^+- with masses ~ 100-300 GeV (the closer to M_Z the more natural). The compressed mass spectrum and associated low energy release from \\tw_1 and \\tz_2 three-body decay makes higgsinos difficult to detect at LHC14, while the other sparticles might be heavy, and possibly even beyond LHC14 reach. In contrast, the International Linear e^+e^- Collider (ILC) with \\sqrt{s}>2m(higgsino) would be a {\\it higgsino factory} in addition to a Higgs boson factory and would serve as a discovery machine for natural SUSY!

  8. Photon Factory activity report, 1988

    International Nuclear Information System (INIS)

    Since the foundation of Photon Factory a decade age, it has played an important role as a unique synchrotron X-ray radiation source in Japan. Installation of various insertion devices, storage of intense positron beam and reduction of beam emittance were the substantial achievements in the last several years. The exploitation of the TRISTAN Accumulation Ring as a synchrotron radiation source has paved the way for a new potential of development. All these activities have brought about the increase of beamlines and the expansion of scientific fronts. Third International Conference on Synchrotron Radiation Instrumentation held in Tsukuba was one of the most highlighted events for the facility. In coming years, it is intended to open new research fields using the promising single bunch beam and circularly polarized wiggler radiation. The TRISTAN Main Ring also will be applied to synchrotron radiation research. The Photon Factory in a national synchrotron radiation research facility affiliated to the National Laboratory for High Energy Physics, and it consists of a 2.5 GeV electron linac, a 2.5 GeV storage ring as a synchrotron light source, beam lines and experimental stations. The operation, improvement and development in respective departments are reported. (Kako, I.)

  9. B factory collider designs and future plans

    International Nuclear Information System (INIS)

    Typical parameters of B factory colliders are presented, along with their justification. Design challenges that arise from these parameter choices are indicated. These challenges appear in both the physics design of the collider and its technological implementation. An overview of the three active B factory projects (PEP-II, KEK-B, and the CESR upgrade) is briefly given, and technical approaches adopted by the projects to deal with the design challenges are outlined. Project status and plans for the various B factory projects are also indicated. Because the problems faced by the designers of B factories are closely related to those that will be faced in the design of a Tau-Charm Factory (τcF), the solutions adopted by the B factory designers can in many cases be carried over to the τcF essentially unchanged. copyright 1996 American Institute of Physics

  13. Photon Factory activity report, 1987

    International Nuclear Information System (INIS)

    The Photon Factory made great strides in 1987. The low emittance operation of the PF ring was achieved in March, and resulted favorably in the increase of brilliance from 2 to 20 times for all the beam lines with high beam stability. At the same time, the installation of inserted devices was under way for all available straight sections of the ring. A 54-pole wiggler-undulator has been commissioned at BL-16. The devices to be inserted in the near future are a multipole wiggler for BL-13, an undulator for BL-19, and an undulator for circular polarized radiation at BL-28. The construction of beam lines continued, and four new beam lines, BL-6, BL-9, BL-16 and BL-17, are now in operation, BL-13 and BL-19 are under construction, and BL-3, BL-5, BL-18, BL-20 and BL-28 are in the design stage. Since its inauguration with four beam lines in 1982, the Photon Factory has grown rapidly, and approaches the goal of operating the PF ring with positrons in full use of its 24 beam ports and the straight sections for inserted devices. The total operation time was limited to 3,000 hours by the budget for fiscal year 1987, and about 80 % of the operation hours were devoted to the experiments of users. The nearly perfect operation of the 400 m long linac has continued in 1987, and has supplied both electrons and positrons to the TRISTAN collision experiment. The light source of a 2.5 GeV electron storage ring was normally operated. (Kako, I.)

    Similar to a super B-factory, a circular Higgs factory will require strong focusing systems near the interaction points and a low-emittance lattice in arcs to achieve a factory luminosity. At electron beam energy of 120 GeV, beamstrahlung effects during the collision pose an additional challenge to the collider design. In particular, a large momentum acceptance at 2 percent level is necessary to retain an adequate beam lifetime. This turns out to be the most challenging aspect in the design of circular Higgs factory. In this paper, an example will be provided to illustrate the beam dynamics in circular Higgs factory, emphasizing on the chromatic optics. Basic optical modules and advanced analysis will be presented. Most important, we will show that 2% momentum aperture is achievable

    Ryu, Ehri

    2014-02-01

    This paper presents a procedure to test factorial invariance in multilevel confirmatory factor analysis. When the group membership is at level 2, multilevel factorial invariance can be tested by a simple extension of the standard procedure. However level-1 group membership raises problems which cannot be appropriately handled by the standard procedure, because the dependency between members of different level-1 groups is not appropriately taken into account. The procedure presented in this article provides a solution to this problem. This paper also shows Muthén's maximum likelihood (MUML) estimation for testing multilevel factorial invariance across level-1 groups as a viable alternative to maximum likelihood estimation. Testing multilevel factorial invariance across level-2 groups and testing multilevel factorial invariance across level-1 groups are illustrated using empirical examples. SAS macro and Mplus syntax are provided.

  6. Photon Factory activity report, 1989

    International Nuclear Information System (INIS)

    At the Photon Factory about 500 experiments are now running annually with about 50 experimental stations, the total operation time of the 2.5 GeV storage ring was 3400 hour in 1989, and the number of users was more than 2000, including 300 scientists from industry. This wide usage of synchrotron radiation has been supported by good performance of the accelerators. The positron beam current of the linac was increased for rapid injection (injection time: 20 min). The entire roof of the Light Source building was covered with thermal insulator (urethane-foam). This has greatly improved the beam stability of the ring. It has been operated at an initial ring current of 350 mA with a life time of 20 hours. Distinctive instrumentation at the Photon Factory has expanded to various fields such as angle-resolved ion-spectroscopy, dispersive EXAFS, trace impurity X-ray fluorescence analysis, plane-wave topography, structure analysis under high pressure, and imaging plates. Recently, experiments of protein structure analysis have been carried out extensively; Sakabe developed a new type of Weissenberg camera for protein crystallography, and about 50 experiments have been done for the past six months by a combination of Sakabe camera and imaging plates. The 2.5 GeV light source is now at an entrance of its harvest season. The TRISTAN Accumulation Ring has been used throughout this year in a time sharing basis with the TRISTAN experiment; twenty minutes for injection to TRISTAN Main Ring and 2 hours for SR experiment. The main subject has been magnetic Compton scattering with circularly polarized wiggler radiation. Such experiences enable us to expand our perspective for research in the following decade; we are investigating the possibility of operating the TRISTAN Main Ring at 6-8 GeV with 6000-pole undulaters, resulting in an extremely brilliant radiation source (Emittance: 0.1 nm·rad at 5 GeV with damping rings).

    Neutrino Factories offer an exciting option for the long-term neutrino physics program. This new type of neutrino facility will provide beams with unique properties. Low systematic uncertainties at a Neutrino Factory, together with a unique and precisely known neutrino flavor content, will enable neutrino oscillation measurements to be made with unprecedented sensitivity and precision. Over recent years, the resulting neutrino factory physics potential has been discussed extensively in the literature. In addition, over the last six years the R&D necessary to realize a Neutrino Factory has been progressing, and has developed into a significant international activity. It is expected that, within about five more years, the initial phase of this R&D program will be complete and, if the community chooses to build this new type of neutrino source within the following decade, neutrino factory technology will be ready for the final R&D phase prior to construction. In this paper (1) an overview is given of the technical ingredients needed for a Neutrino Factory, (2) beam properties are described, (3) the resulting neutrino oscillation physics potential is summarized, (4) a more detailed description is given for one representative Neutrino Factory design, and (5) the ongoing R&D program is summarized, and future plans briefly described.

We will follow the Tritium management process. We need first a gas factory producing the right gas mixture from hydrogen, Deuterium and Tritium storage. Then we could pass through the target factory. It is based on our LMJ single shot experiment and some new development like the injector. Then comes pellet burst and vapour recovery. The Tritium factory has to include the waste recovery, recycling process with gas purification before storage. At least, a nuclear plant is not a classical building. Tritium is also very special... All the design ideas have to be adapted. Many facilities are necessary, some with redundancy. We all have to well known these constraints. Tritium budget will be a major contributor for a material point of view as for a financial one.

    A new signal is proposed for the colour reconnection in the hadronic decay of W+ W- in e+e- collisions. Using Pythia Monte Carlo it is shown that factorial correlators for W+ and W- without colour reconnection are almost identical to unity, while those for the cases with colour reconnection fall down approximately linearly in the log log plot. This signal, being based on the factorial correlator, is more sensitive than the ones using only averaged quantities.

    Full Text Available Latar belakang: Penggunaan metode keluarga berencana (KB oleh Wanita Usia Subur (WUS antara lain dipengaruhi oleh faktor sosial ekonomi. Maka, masalah biaya yang harus dibayar oleh WUS untuk memperoleh pelayanan KB perludi pahami guna keberhasilan program KB Nasional. Metode: Studi menggunakan data Riset Kesehatan Dasar (Riskesdas 2010, bertujuan untuk mengetahui biaya pelayanan KB yang dibayar oleh perempuan usia 10–59 tahun (WUS yang pernah kawin menurut metode KB berdasarkan status ekonomi yang bersangkutan. Analisis data menggunakan analisis deskriptif, analisis bivariat dengan uji statistik chi-square. Hasil: Alat/obat KB disposible terbanyak yang digunakan WUS dari semua golongan status ekonomi adalah metode KB suntik, sedangkan kondom terbanyak digunakan oleh WUS dengan status ekonomi atas banyak. Sekitar 50% WUS dengan status ekonomi (SE rendah membayar biaya pelayanan KB berkisar Rp.10.000–Rp.15.000. Sementara itu WUS dengan SE atas terbanyak membayar sekitar > Rp. 20.000. Terdapat korelasi signifikan antara metode KB dengan biaya dan status ekonomi. Kesimpulan: Metode suntik masih merupakan metode pilihan bagi WUS di Indonesia dan pemilihan metode KB oleh WUS berhubungan dengan status ekonomi mereka. Oleh karena itu promosi kesehatan perlu terus digalakkan agar program KB pemerintah dengan IUD dapat lebih dikenal dan dapat diterima masyarakat. Di samping itu, diperlukan kebijakan khusus (bantuan kepada WUS dengan status ekonomi rendah sehingga IUD dapat diperoleh secara gratis atau setidaknya dengan biaya yang terjangkau.

    Daylight is an essential factor in lightening buildings. Its use is not only oriented to supply illumination to the spaces to provide adequate lightening levels for the optimum execution of their occupants` tasks, but also to supply the appropriate illumination level required in each case for specific functions, as well as to contribute to the psychophysiological health of its users and provide a favorable ambient and the germicide action in the ultraviolet component of the sunlight and besides a portion of vitamin {sup D,} that is needed for people`s health. On the other hand, the rational and efficient use of daylight can contribute to the diminish the consumption of electric power, that is used for the artificial lightning of buildings. This situation is particularly important in hot climates, where the consumption of electricity for lightening interior spaces is huge, mainly in non-dwelling buildings. In this paper the possibilities of the utilization of daylight are explored and analyzed for the purpose of achieving energy savings and the visual thermal and lightning comfort in buildings. [Espanol] La luz natural diurna es un factor indispensable en los edificios.

    The critical analysis is presented as a synthesis of the problem untied since the implementation of the daylight saving time. The often related history is retaken to introduce the reader into the context of the causes of a such program. The geometric aspect of the solar trajectories is discussed and the length of the day as a function of the latitude and the time of the year to have technical elements for the time displacement in a certain region. The technical implementation of the daylight saving time based on three elements is justified: time of dawn and the decline (length of the day), national economic motivation and tourism industry. Stands out that although the daylight saving time schedule has a set of social and economic benefits it is not centered in the individual but in the society as a whole. The errors in handling the information and the misinformation are pointed out as the main causes of the controversy, the discord and the political manipulation of competing groups. [Spanish] El analisis critico se presenta como una sintesis del problema desatado desde la implementacion del horario de verano. La historia muchas veces contada se retoma para introducir al lector en el contexto de las causas de un tal programa. Se discute el aspecto geometrico de las trayectorias solares y la longitud del dia como una funcion de la latitud y de la epoca del ano para tener elementos tecnicos para el desplazamiento horario en una region determinada. Se justifica la implementacion tecnica del horario de verano en funcion de tres elementos: hora de alba y del ocaso (longitud del dia), motivacion economica nacional e industria turistica. Se destaca que si bien el horario de verano tiene un conjunto de beneficios sociales y economicos no se centra en el individuo sino en la sociedad en su conjunto.

  7. Perspectives on Higher Luminosity B-Factories

    International Nuclear Information System (INIS)

    The present B-factories PEP-II and KEKB have reached luminosities of 4-6 x 1033/cm2/s and delivered integrated luminosity at rates in excess of 6 fb-1 per month [1,2]. The recent turn on of these two B-Factories has shown that modern accelerator physics, design, and engineering can produce colliders that rapidly reach their design luminosities and deliver integrated luminosities capable of frontier particle physics discoveries. PEP-II and KEK-B with ongoing upgrade programs should reach luminosities of over 1034/cm2/s in a few years and with more aggressive improvements may reach luminosities of order 4 x 1034/cm2/s by the end of the decade. However, due to particle physics requirements, the next generation B-Factory may require significantly more luminosity. Initial parameters of a very high luminosity e+e- B-Factory or Super B-Factory (SBF) are being developed incorporating several new ideas from the successful operation of the present generation e+e- accelerators [3,4]. A luminosity approaching 1036 cm-2s-1 may be possible. Furthermore, the ratio of average to peak luminosity may be increased by 30% due to continuous injection. The operation of this new accelerator will be qualitatively different from present e+e- colliders due to this continuous injection

    The practice of reproductive medicine in Nigeria is facing new challenges with the proliferation of 'baby factories'. Baby factories are buildings, hospitals or orphanages that have been converted into places for young girls and women to give birth to children for sale on the black market, often to infertile couples, or into trafficking rings. This practice illegally provides outcomes (children) similar to surrogacy. While surrogacy has not been well accepted in this environment, the proliferation of baby factories further threatens its acceptance. The involvement of medical and allied health workers in the operation of baby factories raises ethical concerns. The lack of a properly defined legal framework and code of practice for surrogacy makes it difficult to prosecute baby factory owners, especially when they are health workers claiming to be providing services to clients. In this environment, surrogacy and other assisted reproductive techniques urgently require regulation in order to define when ethico-legal lines have been crossed in providing surrogacy or surrogacy-like services.

  9. Rapid Application Development Using Software Factories

    2012-01-01

    Software development is still based on manufactory production, and most of the programming code is still hand-crafted. Software development is very far away from the ultimate goal of industrialization in software production, something which has been achieved long time ago in the other industries. The lack of software industrialization creates an inability to cope with fast and frequent changes in user requirements, and causes cost and time inefficiencies during their implementation. Analogous to what other industries had done long time ago, industrialization of software development has been proposed using the concept of software factories. We have accepted this vision about software factories, and developed our own software factory which produces three-layered ASP.NET web applications. In this paper we report about our experience with using this approach in the process of software development, and present comparative results on performances and deliverables in both traditional development and development usin...

    The design of a low-energy (4 GeV) neutrino factory (NF) is described, along with its expected performance. The neutrino factory uses a high-energy proton beam to produce charged pions. The {pi}{sup {+-}} decay to produce muons ({mu}{sup {+-}}), which are collected, accelerated, and stored in a ring with long straight sections. Muons decaying in the straight sections produce neutrino beams. The scheme is based on previous designs for higher energy neutrino factories, but has an improved bunching and phase rotation system, and new acceleration, storage ring, and detector schemes tailored to the needs of the lower energy facility. Our simulations suggest that the NF scheme we describe can produce neutrino beams generated by {approx} 1.4 x 10{sup 21} {mu}{sup +} per year decaying in a long straight section of the storage ring, and a similar number of {mu}{sup -} decays.

    With the advent of the deep economic crisis in Argentina on 2001, the recovery of companies through to the creation of the Cooperatives Working Self-Management or Factories Recovered by its workers was constituted as one of the ways in which the salaried disobeyed the increasing unemployment. When the companies turn into recovered factories they tend to leave of side practices that have been seen like imposed by the previous organization and not understanding them as a primary condition for the execution of his tasks. Safety and ergonomics are two disciplines that are no longer considered relevant to the daily work. Therefore this investigation aims to revalue, undergo semantic to give back to a place in every organization analyzed. This research developed a self-diagnostic tool for working conditions, and the environment, present in the recovered factories.

    The Energy Factory is a collaboration of 26 Dutch local water boards in which options for energy saving and energy production are examined. According to the authors, the initiative of the Energy Factory will lead to a reframing of the role of the water boards. Moreover, they explain how the PPP concept (People, Planet, Profit) may act as platform for negotiations between actors who are involved in the Energy Factory. In addition, the PPP concept is used to demonstrate that the Energy Factory will lead to larger social involvement, social entrepreneurship and growing profits [Dutch] De Energiefabriek is een samenwerkingsverband van 26 waterschappen in Nederland waarin wordt gezocht naar mogelijkheden om energie te besparen en zelf energie te produceren.

  19. Conceptual design of a ring beauty factory

    International Nuclear Information System (INIS)

    This paper reports on the design of the B-meson factory with an expected luminosity of 1033-1034 cm-2s-1 in the energy range of 4.5-6.5 GeV per beam under consideration at the Novosibirsk Institute of Nuclear Physics. The facility will consist of two main parts: the injector and the B-meson factory itself. A 100 m linear electron accelerator to 10 GeV was chosen as an injector. Such a linac is the prototype of the linear collider VLEPP. The injector is expected to feed the B-factory with 1010 electrons and positrons per second directly on the experimental energy. The B-meson factory itself will be about 500 m double ring with combined insertions in the interaction region. In both rings up to 20 bunches will be operated simultaneously. The beams interact one with the other at one interaction point (IP) only. Besides the opportunity to operate with a great number of bunches, an enhancement in luminosity is supposed to be achieved due to mini-beta function that results from a strong bunch length decrease, as well as due to the monochromatization collision scheme

    2005-08-15

    A new analytical model for creep life prediction of gas turbine blades is proposed. The ultimate tensile strength is included to reflect heat-to-heat variations in strength. A thermo mechanical analysis is made using the finite element method. With the stress distribution obtained, some creep life prediction models as the Norton-Bailey and Dorn-Bailey models were reviewed as well as the Larson-Miller parameter. The time to failure data obtained with the previous analysis, was used to determine the new creep life prediction model coefficients. The results obtained are in good concordance with experimental data for IN-738-LN gas turbine blades. [Spanish] En el presente trabajo se propone un nuevo modelo analitico para predecir la vida util por termofluencia en alabes de turbinas de gas, donde se incluye el esfuerzo ultimo de tension para reflejar el efecto que tiene la variacion de la temperatura en la rigidez del material. Para lograr esto, primero se hizo un analisis termomecanico del alabe, utilizando el metodo de elementos finitos. Con los esfuerzos obtenidos, se hizo una revision de los modelos de consumo de vida de Norton-Bailey y de Dorn-Bailey. Tambien se utilizo el parametro Larson-Miller para obtener datos de consumo de vida. Con los resultados de los analisis anteriores, fue posible determinar los coeficientes del modelo propuesto. Los resultados obtenidos estan en buena concordancia con los datos experimentales del alabe, y muestran un error menor que el de los modelos revisados.

  3. B-Factory Interaction Region Design

    Science.gov (United States)

    Sullivan, M.

    1997-05-01

    High luminosity B factories are generally high current (1-3 A) e^+e^- storage ring accelerators that operate at a center-of-mass energy equal to the mass of the Υ4S resonance (10.58 GeV). The high beam currents are achieved by storing a large number of bunches (several hundred to several thousand) into each beam. Two designs, the ones located at SLAC and KEK, also have asymmetric beam energies. This imparts a boost to the nearly stationary B mesons formed from the decay of the Υ4S and allows precision vertex tracking detectors to look for a difference between the decay profiles of the matter and anti-matter B mesons thereby observing a violation of CP. Bringing these stored beams into collision is one of the major challenges of any B factory design. In order to achieve high luminosity the beams must be tightly focused. This pushes the final focusing elements close enough to the interaction point to be inside the solenoidal field of the physics detector. In addition, beam related detector backgrounds from synchrotron radiation and scattered beam particles must be kept below an acceptable level. The major B factory designs at Cornell University, KEK, and SLAC have all addressed these problems in various ways that depend on specific accelerator design decisions. This presentation will describe the accelerator choices that affect the interaction region design of a B factory and discuss how the above designs address the challenges posed by a high luminosity B factory.

    Full Text Available A degradação do antimicrobiano digluconato de clorhexidina (DGCH durante armazenamento ou processamento térmico pode formar a 4-cloroanilina (CA, um composto potencialmente carcinogênico. Conseqüentemente, o uso deste sanitizante para descontaminação de carcaças de frangos representa uma fonte de risco para o consumidor, devendo ser avaliada a presença da CA no produto tratado. Um método foi desenvolvido para determinação de resíduos de CA em tecidos de frangos. Após a extração com diclorometano, foi feita a limpeza do extrato em cartucho C18 e quantificação por cromatografia gasosa-espectrometria de massas (CG-EM, sem derivação. A recuperação média (89,2% - CV 9,9%. e o limite de detecção (1,8ng/g foram considerados satisfatórios para os propósitos do estudo. Em amostras tratadas com DGCH e não submetidas a processamento térmico, a quantidade de CA detectada foi relativamente baixa, e provavelmente se originou da solução de tratamento. A fritura e a cocção em forno convencional resultaram em níveis elevados de CA, enquanto que a cocção em panela de pressão não alterou os níveis de CA presentes na amostra crua. Em vista destes resultados e, considerando-se o potencial tóxico da CA, recomenda-se que estes dados sejam levados em consideração quando avaliada a utilização de DGCH como sanitizante de carcaças em abatedouros de aves.The degradation of the antimicrobial agent chlorhexidine digluconate (CHDG during storage or thermal process originates 4-chloroaniline (CA, a compound which is potentially carcinogenic. As the use of this sanitizing agent to decontaminate poultry carcasses in processing plants may represent a risk to the consumers, it is important to search for the presence of CA residues in the treated products. A method was developed to quantify CA in poultry tissues. After dichloromethane extraction, the extract was cleaned on a C18 cartridge and the quantitation was performed, without

This interface allows integrating the computational models virtually, although they have different grids, and that the CFD model registers the data in center cells, whereas the FEA model registers them in the nodes. Pressure, temperature and velocity profiles were obtained for the fluid and, temperature and stress for the solid. The obtained results are compared with experimental data reported in literature obtaining acceptable results. With this work, information for complementary studies is generated, as failure analysis faults and blade life assessment.

    Full Text Available The main idea of this research is to present a concept of integration of a beer factory in a new urban reality. Nowadays, modern development of industrial architecture enables beer factories to leave their typical locations in industrial zones and draw nearer to their customers. To design a modern industrial complex incorporating the ideas of the contemporary way of designing an industrial facility with a clear and indicative architectural expression of its hybrid character requires great skilfulness. Using a linear grid, the concept of this project will be developed in a composition consisting of several strips. This kind of structure creates a compositional equivalence from strip to strip, integrating the natural and the urban, the public and the private.

    Full Text Available Work safety is of great importance in all industrial activities. The Norm NR15 of the Brazilian law determines that the work environment be tailored to employees to minimize biological, ergonomic, physical, chemical risks and accidents. The aim of this study was to evaluate the exposure of intermittent noise in a daily dose to workers in furniture factories. Measurements were made with a sound level meter and dosimeter in a workday of eight hours in 14 furniture factories located in the South of Minas Gerais. Noise values ranged from 66.0 to 117.4 dB(A. At a dose of 8 working hours it was observed that the values exceed the tolerance limit of a unit, being from 2.76 to 30.52 for minimum and maximum units, respectively.

  17. Portable Material Culture and Death Factory Auschwitz

    Directory of Open Access Journals (Sweden)

    2007-11-01

    Full Text Available Like any other factory, the death factory of Auschwitz consumed primary materials and produced secondary products. Unique to Auschwitz, though, is that the primary material consumed was human life; not just the life of the breathing human body, but also the material possessions associated with that life. The detritus of this most efficient genocide – clothing, jewellery, food, corpses – was appropriated and put to new uses by the SS and the prisoners. Others have recognised the various postwar material cultural outcomes of the camp: the writing, the film, the theatre, the art, the tourism. This article, however, demonstrates that the material culture of Auschwitz is not a phenomenon exclusive to the postwar era. It focuses on the fact that inside the camp during the war, despite the landscape of death and deprivation, intimate interaction between humans and material culture continued.

    In this report we describe a design for a high-luminosity Asymmetric B Factory to be built in the PEP tunnel on the SLAC site. This proposal, a collaborative effort SLAC, LBL, and LLNL, is the culmination of more than two years of effort aimed at the design and construction of an asymmetric e{sup +}e{sup {minus}} collider capable of achieving a luminosity of L = 3 {times} 10{sup 33} cm{sup {minus}2} s{sup {minus}1}. The configuration adopted utilizes two storage rings, and electron ring operating at 9 GeV and a positron ring at 3.1 GeV, each with a circumference of 2200 m. The high-energy ring is an upgrade of the PEP storage ring at SLAC; all PEP magnets and most power supplies will be reused. The upgrade consists primarily of replacing the PEP vacuum chamber and RF system with newly designed versions optimized for the high-current environment of the B Factory. The low-energy ring will be newly constructed and will be situated atop the high-energy ring in the PEP tunnel. Utilities already installed in the PEP tunnel are largely sufficient to operate the two B Factory storage rings.

    We update theoretical studies of the physics opportunities presented by {mu}{sup +} {mu}{sup -} Higgs factories. Interesting measurements of the Standard Model Higgs decays into {bar b}b, {tau}{sup +} {tau}{sup -} and WW* may be possible if the Higgs mass is less than about 160 GeV, as preferred by the precision electroweak data, the mass range being extended by varying appropriately the beam energy resolution. A suitable value of the beam energy resolution would also enable the uncertainty in the b-quark mass to be minimized, facilitating measurements of parameters in the MSSM at such a first {mu}{sup +} {mu}{sup -} Higgs factory. These measurements would be sensitive to radiative corrections to the Higgs-fermion-antifermion decay vertices, which may violate CP. Radiative corrections in the MSSM may also induce CP violation in Higgs-mass mixing, which can be probed via various asymmetries measurable using polarized {mu}{sup +} {mu}{sup -} beams. In addition, Higgs-chargino couplings may be probed at a second {mu}{sup +} {mu}{sup -} Higgs factory.

    To the interior of the Generation of Electrical Equipment (GEE) of the Instituto de Investigaciones Electricas, one of the main activities is the diagnosis of the electrical equipment in service. It is well known that the power equipment represents a strong investment that requires the guarantee that it has been manufactured, installed and operated satisfactorily. The life expectancy of these devices is of thirty years, however, many of them already have surpassed that expectation. The rehabilitation or substitution of the equipment implies new investments that are needed for an evaluation of the real condition of the equipment to carry out such rehabilitation. One of the tools necessary to carry out the diagnosis, is a movable laboratory that facilitates all the necessary tools to perform a meticulous analysis that would allow, the client, to make high cost decisions. The application of the movable laboratory is advisable from the inauguration of the equipment. The electrical mechanisms are factory tested in accordance with standardized protocols; it guarantees the fulfillment of the necessary requirements for a correct operation. Nevertheless, when taking them to the assembly site, these are subjected to a series of processes and mechanical stresses that could alter the equipment conditions and its integrity.

    Full Text Available La evolución biológica es el resultado de una interacción entre especializaciones adaptativas y constreñimientos filogenéticos. En cuanto a mecanismos de aprendizaje, el énfasis en décadas recientes se ha puesto en el estudio de especializaciones adaptativas a partir de los descubrimientos en las áreas de aversiones gustativas y aprendizaje de evitación durante la década de 1960. El enfoque adaptativo se ha presentado a menudo como el único plausible desde el punto de vista biológico. Sin embargo, tanto la evidencia empírica como recientes descubrimientos en biología evolutiva indican la existencia de un grado notable de estabilidad de procesos biológicos, "incluyendo el aprendizaje. Los mecanismos que subyacen a procesos de adquisición, discriminación y memoria espacial, entre otros, parecen ser generales y estar basados en aspectos estables de la organización del telencéfalo de los vertebrados. Sin embargo, existe también evidencia de divergencia que sugiere la evolución de procesos emocionales de mediación en el aprendizaje instrumental en la línea de los mamíferos. Adaptación y estabilidad parecen ser ambos esenciales para comprender la evolución del aprendizaje en los vertebrados.

    In this work the problems of the transient overvoltage produced in the components that integrate the synchronous generators installed in industrial systems of medium voltage are approached. The development of a mathematical model in phase components for the synchronous generator is presented. The model includes a current saturation transformer, a system of static excitation and a scheme of grounding by low impedance through an energy cable. In the formulation the effect of the dampening windings is neglected since the interest is only to evaluate the effect of the initial transient overvoltage. Also, symmetry in the phases is considered and the saturation is neglected. The proposed mathematical model was evaluated through cases of simulation using real data of a typical industrial system. Also some tests were conducted in laboratories that, qualitatively, endorse the results obtained by simulation. Two real cases of electrical equipment fault by effect of transient overvoltage in industrial centers in Mexico were analyzed, with generators grounded through high impedance. [Spanish] En este trabajo se aborda la problematica de los sobrevoltajes transitorios producidos en los componentes que integran los generadores sincronos instalados en sistemas industriales de mediana tension.

    The Industry 4.0 vision anticipates that internet technologies will find their way into future factories replacing traditional components by dynamic and intelligent cyber-physical systems (CPS) that combine the physical objects with their digital representation. Reducing the gap between the real and digital world makes the factory environment more flexible, more adaptive, but also more complex for the human workers. Future workers require interdisciplinary competencies from engineering, information technology, and computer science in order to understand and manage the diverse interrelations between physical objects and their digital counterpart. This paper proposes a mixed-reality based learning environment, which combines physical objects and visualisation of digital content via Augmented Reality. It uses reality-based interaction in order to make the dynamic interrelations between real and digital factory visible and tangible. We argue that our learning system does not work as a stand-alone solution, but should fit into existing academic and advanced training curricula.

    The paper shows the hydrodynamic analysis of the Jaruco-Aguacate aquifer using an unsteady groundwater flow mathematical model. The simulation includes conditions before and after pumping from a well filed, called El Gato, which is considered, as the most important water source for Havana city. The system is closed to the sea and conformed by an unconfined karstic aquifer with a well defined storage zone; its natural discharge flows through two spring groups. Results obtained with the model for the main spring discharge are near to the measured values, i. e. around 5 m{sup 3}/dec as the mean value for the period without main pumping station. Flow is reduced to 2.5-1.5 m{sup 3}/sec during pumping period but there are no data to confirm this result. Besides, a detailed study of the open boundary of the system is done when piezometric head variation in time is known. The mathematical modelling has been able to simulate the aquifer in its most general conception, in its regional as well as local representation, with a mean deviation of simulated head from observed values less than one meter in both analysed simulated periods.

    The Solar Laboratory of Energy (LES) of the Universidad Nacional Autonoma de Mexico (UNAM) was designed to be comfortable in spite of the extreme climate where it was built. One of the novel characteristics was the shield type ceiling used in cubicles. In order to compare the effect that had had with respect to the environmental conditions, one had to resort to an exergy analysis, since exergy is a measurement of the capacity of the energy to carry out a work. As a first system the data of the national meteorological system as initial conditions were used. The comparative system used as initial conditions the temperature and relative humidity measurements obtained in 1992 in a cubicle of the LES. Both systems were taken as open. The final conditions were settled at 25 Celsius degrees and 50% of relative humidity in a first case and variables (with respect to the perimeter a comfort zone) in a second case. The saving obtained was of 69% and 33% respectively. Although it is not possible to determine what percentage corresponds to the exclusive saving of the ceiling shield, we see that the cover all altogether, presents a significant exergy saving in respect to modifying the environmental conditions directly. [Spanish] El Laboratorio de Energia Solar (LES) de la Universidad Nacional Autonoma de Mexico (UNAM) fue disenado para ser confortable a pesar del clima extremoso donde fue construido. Una de las caracteristicas novedosas fue el uso de techo tipo escudo en cubiculo. Para comparar el efecto que se tuvo respecto a las condiciones ambientales, se recurrio a un analisis exergetico, ya que la exergia es una medida de la capacidad de la energia para realizar un trabajo. Como un primer sistema se utilizaron los datos del sistema meteorologico nacional como condiciones iniciales. El sistema comparativo utilizo como condiciones iniciales las mediciones de temperatura y humedad relativas obtenidas en 1992 en un cubiculo del LES. Ambos sistemas fueron tomados como abiertos

    We study the factorial moments (Fq), the factorial cumulants (Kq) and the ratio of Kq to Fq (Hq = Kq=Fq) in pp/pp collisions using an updated approach, in which the multiplicity distribution is related to the eikonal function. The QCD inspired eikonal model adopted contains contributions of quark-quark, quark-gluon and gluon-gluon interactions. Our work shows that the approach can reproduce the collision energy dependence of the Fq moments, correctly predicts that the first minimum of the Hq ...

    We present the results of applying new object classification techniques to the supernova search of the Nearby Supernova Factory. In comparison to simple threshold cuts, more sophisticated methods such as boosted decision trees, random forests, and support vector machines provide dramatically better object discrimination: we reduced the number of non-supernova candidates by a factor of 10 while increasing our supernova identification efficiency. Methods such as these will be crucial for maintaining a reasonable false positive rate in the automated transient alert pipelines of upcoming large optical surveys.

  16. Muon Acceleration Concepts for Future Neutrino Factory

    2016-05-01

    Here, we summarize current state of concept for muon acceleration aimed at future Neutrino Factory. The main thrust of these studies was to reduce the overall cost while maintaining performance through exploring interplay between complexity of the cooling systems and the acceptance of the accelerator complex. To ensure adequate survival of the short-lived muons, acceleration must occur at high average gradient. The need for large transverse and longitudinal acceptances drives the design of the acceleration system to initially low RF frequency, e.g. 325 MHz, and then increased to 650 MHz, as the transverse size shrinks with increasing energy. High-gradient normal conducting RF cavities at these frequencies require extremely high peak-power RF sources. Hence superconducting RF (SRF) cavities are chosen. Here, we considered two cost effective schemes for accelerating muon beams for a stagable Neutrino Factory: Exploration of the so-called 'dual-use' linac concept, where the same linac structure is used for acceleration of both H− and muons and alternatively, the SRF efficient design based on multi-pass (4.5) 'dogbone' RLA, extendable to multi-pass FFAG-like arcs.

  17. Photon factory accelerator status and activities

    International Nuclear Information System (INIS)

    The present report addresses the Photon Factory, a user-based facility for synchrotron-radiation research at the National Laboratory for High Energy Physics (KEK) in Japan. It consists of a 2.5 GeV storage ring and an electron-positron linac. Its construction started in 1978 and the accelerators were commissioned in 1982. The Photon Factory storage ring is a dedicated synchrotron-radiation source with a critical photon energy of 4 keV. There are 23 spaces in which front-ends (beamlines) can be installed for introducing synchrotron radiation into the experimental hall. Twenty front-ends are available for user experiments. The report particularly describes the status of the linac and the storage ring, focusing on major features of the linac operation and storage ring operation. The recent improvements are then outlined, focusing on positron beam injection and operation, improvement of the high-power pulsed klystron, monitor and control system, daily drift of the light axis, and operation of the new superconducting vertical wiggler. The accelerator activities are then described, centering on the test linac and a plan to use the TRISTAN MR as a synchrotron radiation source. (N.K.)

  18. Particle identification at an asymmetric B Factory

    International Nuclear Information System (INIS)

    Particle identification systems are an important component of any detector at a high-luminosity, asymmetric B Factory. In particular, excellent hadron identification is required to probe CP violation in B0 decays to CP eigenstates. The particle identification systems discussed below also provide help in separating leptons from hadrons at low momenta. We begin this chapter with a discussion of the physics motivation for providing particle identification, the inherent limitations due to interactions and decays in flight, and the requirements for hermiticity and angular coverage. A special feature of an asymmetric B Factory is the resulting asymmetry in the momentum distribution as a function of polar angle; this will also be quantified and discussed. In the next section the three primary candidates, time-of-flight (TOF), energy loss (dE/dx), and Cerenkov counters, both ring-imaging and threshold, will be briefly described and evaluated. Following this, one of the candidates, a long-drift Cerenkov ring-imaging device, is described in detail to provide a reference design. Design considerations for a fast RICH are then described. A detailed discussion of aerogel threshold counter designs and associated R ampersand D conclude the chapter. 56 refs., 64 figs., 13 tabs

    A Super Flavor Factory, an asymmetric energy e{sup +}e{sup -} collider with a luminosity of order 10{sup 36} cm{sup -2} s{sup -1}, can provide a sensitive probe of new physics in the flavor sector of the Standard Model. The success of the PEP-II and KEKB asymmetric colliders in producing unprecedented luminosity above 10{sup 34} cm{sup -2} s{sup -1} has taught us about the accelerator physics of asymmetric e{sup +}e{sup -} collider in a new parameter regime. Furthermore, the success of the SLAC Linear Collider and the subsequent work on the International Linear Collider allow a new Super-Flavor collider to also incorporate linear collider techniques. This note describes the parameters of an asymmetric Flavor-Factory collider at a luminosity of order 10{sup 36} cm{sup -2} s{sup -1} at the Y(4S) resonance and about 10{sup 35} cm{sup -2} s{sup -1} at the {tau} production threshold. Such a collider would produce an integrated luminosity of about 10,000 fb{sup -1} (10 ab{sup -1}) in a running year (10{sup 7} sec) at the Y(4S) resonance. In the following note only the parameters relative to the Y(4S) resonance will be shown, the ones relative to the lower energy operations are still under study.

    In the preliminary design and diagnosis of rotary machines is very common to utilize simple calculation methods for the mechanical and thermal stresses, dynamic and thermodynamic analysis and flow of fluids in this machines (Gutierrez et al., 1989). The analysis with these methods provides the necessary results for the project initial stage of the machine. Later on, more complex tools are employed to refine the design of some machine components. In the Gutierrez report et al., (1989) 34 programs were developed for the preliminary design and diagnosis of rotating equipment; in this article, one of them is presented in which a method for the analysis of mechanical and thermal stresses is applied in discs of uniform or variable thickness that are normally found in turbomachines and rotary equipment.

  8. RI beam factory project at RIKEN

    International Nuclear Information System (INIS)

    The RI Beam Factory is being proposed at RIKEN, which is a project to construct two superconducting ring cyclotrons (SRC-4 and SRC-6), experimental storage rings (MUSES) and experimental facilities. Heavy ions are to be accelerated to energies of up to 400 AMeV for light nuclei and 150 AMeV for the heaviest nuclei by the SRC-6 and up to 1400 AMeV in the MUSES. Wide varieties of radioactive nuclear beams are to be supplied as secondary beams. Electrons, stable nuclei, and highly charged ions in addition to radioactive nuclei can be stored in the storage rings. The MUSES provides various collision methods, such as colliding, merging, and internal target modes. A few of the selected new nuclear-physics opportunities are discussed briefly. (author)

  9. AutoPyFactory and the Cloud

    Caballero, J; The ATLAS collaboration; Love, P

    2013-01-01

    AutoPyFactory (APF) is a next-generation pilot submission framework that has been used as part of the ATLAS workload management system (PANDA) for two years. APF is reliable, scalable, and offers easy and flexible configuration. Using a plugin-based architecture, APF polls for information from configured information and batch systems (including grid sites), decides how many additional pilot jobs are needed, and submits them. With the advent of cloud computing, providing resources goes beyond submitting pilots to grid sites. Now, the resources on which the pilot will run also need to be managed. Handling both pilot submission and controlling the virtual machine life cycle (creation, retirement, and termination) from the same framework allows robust and efficient management of the process. In this paper we describe the design and implementation of these virtual machine management capabilities of APF. Expanding on our plugin-based approach, we allow cascades of virtual resources associated with a job queue. A si...

    Exposure to organic solvents in footwear manufacturing industry came from the glues used adhering the shoe parts to each other. Benzene was the first solvent used in shoe factories until the evidence of its capacity to cause leukaemia. Then, the demonstration that exposure to n-hexane was related to distal polyneuropathy limited the use of this substance. After that, results of neurotoxicological studies conducted on workers exposed to different mixtures of organic solvents make necessary prevention measure directed to a progressive reduction of air dispersion of these chemicals. Today exposure to solvents in workplaces is regulated by health based exposure limit values that should warranty absence of central nervous system effects. One of the most important rules of occupational medicine is verify that these exposure levels are really health protective also for workers with increased susceptibility. PMID:22697025

    2008-01-01

    Operation of the B-Factories (PEP-II and KEKB) has been very successful, both having exceeded their design peak and integrated luminosity and provided a huge amount of good data to the experiments. Proposal for upgrades, in order to achieve about two order of magnitude larger luminosity, are in progress in Japan, with Super-KEKB, and in Europe, with SuperB. Very high beam intensity, very short bunch length and low Interaction Point beta-functions are the key points of the Japanese design, very challenging for the hardware components (RF, vacuum). On the other hand SuperB exploits a new collision scheme, namely large Piwinski angle and "crab waist", which will allow to reach a luminosity two order of magnitude larger without increasing beam currents and decreasing bunch lengths. In this talk the present status of the two projects will be reviewed.

    Full Text Available Atherosclerosis or arterial stiffening is a gradual disease that restricts the normal blood flow in different areas of body and maylead to secondary illnesses as myocardial infarction and cerebral stroke. Innumerable factors are related to the development ofatherosclerosis, among them are the dyslipidemia; genetic factors; arterial hypertension; diabetes mellitus; obesity; smoking;lack of exercise; pulmonary infection by Chlamydia and stress. Due to multi-factorial atherosclerosis characteristics,innumerable drugs, with differentiated mechanisms of action, are being elaborated to be used in prevention and control of thisdisease. However, beyond the pharmacological therapy, a balanced diet, physical activity and elimination of risk habits, assmoking, also are need for controlling atherosclerosis progression, as well as for the increase of expectative and quality of life

    Full Text Available The study of mental processes is at the forefront of research in cognitive psychology. However, the ability to identify the architectures responsible for specific behaviors is often quite difficult. To alleviate this difficulty, recent progress in mathematical psychology has brought forth Systems Factorial Technology (SFT; Townsend & Nozawa, 1995. Encompassing a series of analyses, SFT can diagnose and discriminate between five types of information processing architectures that possibly underlie a mental process. Despite the fact that SFT has led to new discoveries in cognitive psychology, the methodology itself remains far from intuitive to newcomers. This article therefore seeks to provide readers with a simple tutorial and a rudimentary introduction to SFT. This tutorial aims to encourage newcomers to read more about SFT and also to add it to their repertoire of analyses.

    International Nuclear Information System (INIS)

    Over the last year considerable progress has been achieved on both technical and political fronts. Hardware studies have continued on both magnet power supplies and on rf cavities - the latter work gaining an extra dimension from a recently-instituted formal collaboration with LAMPF. A racetrack-shaped lattice is being considered in conjunction with a three-element slow extraction system in an effort to reduce losses to the 0.1% level. British Columbia has agreed to fund the buildings and tunnels (Cdn $87M) and is making the KAON Factory its tope priority project with the Canadian federal government. A joint federal-provincial delegation has traveled abroad and found that a number of countries would consider significant contributions to the cost. Government approval contingent upon such contributions is anticipated later in 1988, together with preconstruction R and D funds

  16. Evolution of the Factory 1975-2006

    International Nuclear Information System (INIS)

    Since it was founded in 1973. Equipos Nucleares (ENSA) has been actively present in the nuclear market. This was the reason for its creation and for which it was organized from the very beginning, by designing a company with a nuclear structure and mentality. The author reviews the history and evolution of the Factory- more than a workshop- and describes its different stages, which were strongly affected by the unexpected evolution of a diminishing market- an inexistent market the likes to say- and also stresses the extraordinary difficulty of its work and the determination to remain in the nuclear market. He acknowledges the people and the culture of ENSA emphasizing their dedication, generosity, flexibility, training and enthusiasm, and stresses their stake in being the best and to attain excellence in the quality of supplies, meeting deadlines and customer satisfaction, identifying these as fundamental factors of the company's legacy. Having a better Factory is possible by improving its technological capability through researching and developing its processes, automating and robotizing manufacturing and inspection activities, and simplifying its operating systems. A result of these efforts is the continuous international presence as a supplier and collaborator with the world's leading designers, which has consolidated it as a reference supplier on the American market. Of not is the supply to the market of its different product lines a result of combining its design and manufacturing capabilities with its flexibility and size, all of which contribute to ENSA's wealth, diversity and appeal. ENSA is aware of the forthcoming resurgence of the new nuclear market. It is preparing for the future by renewing and upgrading its manufacturing facilities and implementing new systems techniques- Lean Manufacturing and Six Sigma-into its Annual Improvement Plans to favor and drive its technological capability and competitiveness and to respond to the increasingly demanding

    2013-01-01

    We study the factorial moments (Fq), the factorial cumulants (Kq) and the ratio of Kq to Fq (Hq = Kq=Fq) in pp/pp collisions using an updated approach, in which the multiplicity distribution is related to the eikonal function. The QCD inspired eikonal model adopted contains contributions of quark-quark, quark-gluon and gluon-gluon interactions. Our work shows that the approach can reproduce the collision energy dependence of the Fq moments, correctly predicts that the first minimum of the Hq lies around q = 5 and qualitatively reproduces the oscillations of the Hq moments, as shown in the experimental data and predicted by QCD at preasymptotic energy. The result of this study seems to indicate that the Hq oscillations are manifestation of semihard component in the multiparticle production process. Predictions for multiplicity distribution and Hq moments at the LHC energy of 14 TeV are presented.

The main objective of the study is to analyze the role of infrastructure through the linkage analysis, dispersion effect analysis, multiplier effect analysis, and the investment effect analysis. The scope of infrastructure is only referred to electricity, gas and water, and construction sector. The data used for this study is the 2005 Indonesian Input-Output Table. The result of the study has shown that infrastructure has a higher backward linkage than its forward. In addition, all of the infrastructure sectors has shown more than one dispersion coefficient and conversely has revealed less than one value for the dispersion sensitivity. Which means that infrastructure had a better capability to support the development of its upstream sectors than its downstream. Infrastructure has a positive multiplier effect toward the other sectors. The growth of the investment in the electricity, gas and water sector has given the biggest effect toward the change of the total outpu, while the water sector has given the biggest effect toward the change in the total income,  and road, bridge and port sector has given the biggest effect toward the change in the total labour.

    The safety during the maintenance interventions is treated in limited manner and in general independent of the systems of management of the maintenance. This variable is affected by multiple technical or human factors many times subjective and difficult to quantifying, what limits the design of preventive plans. However, some factors constitute common points: the isolation configurations during the free ways (bank drafts in the oil industry) and the human errors associated to their violation. This characteristic allowed to develop the analysis of such situations through the methodology of fault trees that it links faults of teams and human errors cohesively. The methodology has been automated inside the MOSEG Win Ver 1.0 code and the same one can embrace from the analysis of a particular situation of free way until that of a complete strategy of maintenance from the point of view of the safety of the maintenance personal.

    1995-01-01

    The quality movement, that has had in recent years a dramatic impact on all industrial sectors, has recently reached the system and software industry. Although some concepts of quality management, originally developed for other product types, can be applied to software, its specificity as a product which is developed and not produced requires a special approach. This paper introduces a quality paradigm specifically tailored on the problem of the systems and software industry. Reuse of products, processes and experiences originating from the system life cycle is seen today as a feasible solution to the problem of developing higher quality systems at a lower cost. In fact, quality improvement is very often achieved by defining and developing an appropriate set of strategic capabilities and core competencies to support them. A strategic capability is, in this context, a corporate goal defined by the business position of the organization and implemented by key business processes. Strategic capabilities are supported by core competencies, which are aggregate technologies tailored to the specific needs of the organization in performing the needed business processes. Core competencies are non-transitional, have a consistent evolution, and are typically fueled by multiple technologies. Their selection and development requires commitment, investment and leadership. The paradigm introduced in this paper for developing core competencies is the Quality Improvement Paradigm which consists of six steps: (1) Characterize the environment, (2) Set the goals, (3) Choose the process, (4) Execute the process, (5) Analyze the process data, and (6) Package experience.

    Full Text Available Al centro di questo contributo vi è l’analisi eticogiuridica degli atti normativi disciplinanti le analisi genetiche in vari contesti, ad esempio, ricerca medica, terapia, medicina legale e così dicendo. Lo scopo è di mettere in evidenza i valori ai quali sono state improntate alcune risposte normative. Pertanto, dopo una ricognizione delle varie tipologie di analisi genetiche e dei loro possibili impieghi, il presente lavoro confronta i testi normativi internazionali, europei e nazionali (Austria, Francia, Germania, Svizzera, al fine di individuare la strada percorsa e da percorrere per salvaguardare il più possibile certi valori ritenuti fondamentali per la preservazione sia dell’autonomia individuale, sia dell’eguaglianza tra i consociati. Si concluderà che non tutte le norme che disciplinano le analisi genetiche possono considerarsi rispettose dei diritti fondamentali garantiti a tutti gli individui.

  1. VLBA Reveals Dust-Enshrouded "Supernova Factory"

    Science.gov (United States)

    2003-05-01

    Using the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope, astronomers have discovered a newly-exploded star, or supernova, hidden deep in a dust-enshrouded "supernova factory" in a galaxy some 140 million light-years from Earth. "This supernova is likely to be part of a group of super star clusters that produce one such stellar explosion every two years," said James Ulvestad, of the National Radio Astronomy Observatory (NRAO) in Socorro, NM. "We're extremely excited by the tremendous insights into star formation and the early Universe that we may gain by observing this 'supernova factory,'" he added. Ulvestad worked with Susan Neff of NASA's Goddard Space Flight Center in Greenbelt, MD, and Stacy Teng, a graduate student at the University of Maryland, on the project. The scientists presented their findings to the American Astronomical Society's meeting in Nashville, TN. "These super star clusters likely are forming in much the same way that globular clusters formed in the early Universe, and thus provide us with a unique opportunity to learn about how some of the first stars formed billions of years ago," Neff said. The cluster is in an object called Arp 299, a pair of colliding galaxies, where regions of vigorous star formation have been found in past observations. Since 1990, four other supernova explosions have been seen optically in Arp 299. Observations with the NSF's Very Large Array (VLA) earlier showed a region near the nucleus of one of the colliding galaxies which had all the earmarks of prolific star formation. The astronomers focused on this region, prosaically dubbed "Source A," with the VLBA and the NSF's Robert C. Byrd Green Bank Telescope in 2002, and found four objects in this dusty cloud that are likely young supernova remnants. When they observed the region again in February 2003, there was a new, fifth, object located only 7 light-years from one of the previously detected objects. More observations on April 30-May

  2. Forecasting Sales in a Sugar Factory

    Full Text Available Beets’ cultivation and sugar production represent one of the most important parts of Greek agricultural economy. A careful and well-organized planning of the production as well as the determination of an accurate safety stock is important for sugar industry, as for many other companies and organizations, in order to define the production quantity which leads to maximum revenues and profits. Forecasting, and especially widely used statistical forecasting techniques, is the best way for policymakers to organize their activities and company’s production and make the appropriate adjustments. Apparently, management information systems and forecasting support packages play a leading role in this area, since the amount of data under process is usually quite large and demands an automated procedure to effectively produce and evaluate forecasts. In this case study, “Pythia”, an expert forecasting platform developed by the Forecasting and Strategy Unit of the National Technical University of Athens, was implemented on a monthly data series regarding sugar sales of a Greek sugar factory for the years 2000-2005, bringing theory and practice together. Additionally, the methods or combinations of methods which are well suited for this time series are highlighted based on three error indices. Finally, the results of the study and conclusions are considered and perspectives of progress and development in the field of forecasting are contemplated.

    The factory of the future will require an operating methodology which effectively utilizes all of the elements of product design, manufacturing and delivery. The process must respond rapidly to changes in product demand, product mix, design changes or changes in the raw materials. To achieve agility in a manufacturing operation, the design and development of the manufacturing processes must focus on customer satisfaction. Achieving greatest results requires that the manufacturing process be considered from product concept through sales. This provides the best opportunity to build a quality product for the customer at a reasonable rate. The primary elements of a manufacturing system include people, equipment, materials, methods and the environment. The most significant and most agile element in any process is the human resource. Only with a highly trained, knowledgeable work force can the proper methods be applied to efficiently process materials with machinery which is predictable, reliable and flexible. This paper discusses the affect of each element on the development of agile manufacturing systems.

  4. The Gamma Factory proposal for CERN

    2015-01-01

    This year, 2015, marks the centenary of the publication of Einsteins Theory of General Relativity and it has been named the International Year of Light and light-based technologies by the UN General Assembly. It is thus timely to discuss the possibility of broadening the present CERN research program by including a new component based on a novel concept of the light source which could pave a way towards a multipurpose Gamma Factory. The proposed light source could be realized at CERN by using the infrastructure of the existing accelerators. It could push the intensity limits of the presently operating light-sources by at least 7 orders of magnitude, reaching the flux of the order of 10^17 photons/s, in the particularly interesting gamma-ray energy domain of 1 < Ephoton < 400 MeV. This domain is out of reach for the FEL-based light sources. The energy-tuned, quasi-monochromatic gamma beams, together with the gamma-beam-driven, high intensity secondary beams of polarized positrons, polarized muons, neutro...

  5. New Physics at a Super Flavor Factory

    Browder, Thomas E; Pirjol, Dan; Soni, Amarjit; Zupan, Jure

    2009-01-01

    The potential of a Super Flavor Factory (SFF) for searches of New Physics is reviewed. While very high luminosity B physics is assumed to be at the core of the program, its scope for extensive charm and tau studies are also emphasized. The possibility to run at the Upsilon(5S) as well as at the Upsilon(4S) is also very briefly discussed; in principle, this could provide very clean measurements of B_s decays. The strength and reach of a SFF is most notably due to the possibility of examining an impressive array of very clean observables. The angles and the sides of the unitarity triangle can be determined with unprecedented accuracy. These serve as a reference for New Physics (NP) sensitive decays such as B^+ ->tau^+ nu and penguin dominated hadronic decay modes, providing tests of generic NP scenarios with an accuracy of a few percent. Besides, very precise studies of direct and time dependent CP asymmetries in radiative B decays and forward-backward asymmetry studies in B -> X_s l^+ l^- and numerous null tes...

  6. Future Accelerators, Muon Colliders, and Neutrino Factories

    2001-12-19

    Particle physics is driven by five great topics. Neutrino oscillations and masses are now at the fore. The standard model with extensions to supersymmetry and a Higgs to generate mass explains much of the field. The origins of CP violation are not understood. The possibility of extra dimensions has raised tantalizing new questions. A fifth topic lurking in the background is the possibility of something totally different. Many of the questions raised by these topics require powerful new accelerators. It is not an overstatement to say that for some of the issues, the accelerator is almost the experiment. Indeed some of the questions require machines beyond our present capability. As this volume attests, there are parts of the particle physics program that have been significantly advanced without the use of accelerators such as the subject of neutrino oscillations and many aspects of the particle-cosmology interface. At this stage in the development of physics, both approaches are needed and important. This chapter first reviews the status of the great accelerator facilities now in operation or coming on within the decade. Next, midrange possibilities are discussed including linear colliders with the adjunct possibility of gamma-gamma colliders, muon colliders, with precursor neutrino factories, and very large hadron colliders. Finally visionary possibilities are considered including plasma and laser accelerators.

    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 (Mason and Suri, 2011; McDonnell et al., 2012; de Leeuw, 2015; 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.

  17. Make your company a talent factory.

    Ready, Douglas A; Conger, Jay A

    2007-06-01

    Despite the great sums of money companies dedicate to talent management systems, many still struggle to fill key positions - limiting their potential for growth in the process. Virtually all the human resource executives in the authors' 2005 survey of 40 companies around the world said that their pipeline of high-potential employees was insufficient to fill strategic management roles. The survey revealed two primary reasons for this. First, the formal procedures for identifying and developing next-generation leaders have fallen out of sync with what companies need to grow or expand into new markets. To save money, for example, some firms have eliminated positions that would expose high-potential employees to a broad range of problems, thus sacrificing future development opportunities that would far outweigh any initial savings from the job cuts. Second, HR executives often have trouble keeping top leaders' attention on talent issues, despite those leaders' vigorous assertions that obtaining and keeping the best people is a major priority. If passion for that objective doesn't start at the top and infuse the culture, say the authors, talent management can easily deteriorate into the management of bureaucratic routines. Yet there are companies that can face the future with confidence. These firms don't just manage talent, they build talent factories. The authors describe the experiences of two such corporations - consumer products icon Procter & Gamble and financial services giant HSBC Group -that figured out how to develop and retain key employees and fill positions quickly to meet evolving business needs. Though each company approached talent management from a different direction, they both maintained a twin focus on functionality (rigorous talent processes that support strategic and cultural objectives) and vitality (management's emotional commitment, which is reflected in daily actions).

  19. Black hole as a wormhole factory

    Kim, Sung-Won; Park, Mu-In

    2015-12-01

    There have been lots of debates about the final fate of an evaporating black hole and the singularity hidden by an event horizon in quantum gravity. However, on general grounds, one may argue that a black hole stops radiation at the Planck mass (ħc / G) 1 / 2 ∼10-5 g, where the radiated energy is comparable to the black hole's mass. And also, it has been argued that there would be a wormhole-like structure, known as "spacetime foam", due to large fluctuations below the Planck length (ħG /c3) 1 / 2 ∼10-33 cm. In this paper, as an explicit example, we consider an exact classical solution which represents nicely those two properties in a recently proposed quantum gravity model based on different scaling dimensions between space and time coordinates. The solution, called "Black Wormhole", consists of two different states, depending on its mass parameter M and an IR parameter ω: For the black hole state (with ωM2 > 1 / 2), a non-traversable wormhole occupies the interior region of the black hole around the singularity at the origin, whereas for the wormhole state (with ωM2 Censorship" by the existence of a wormhole-like structure which protects the naked singularity even after the black hole evaporation. One could understand the would-be wormhole inside the black hole horizon as the result of microscopic wormholes created by "negative" energy quanta which have entered the black hole horizon in Hawking radiation process; the quantum black hole could be a wormhole factory! It is found that this speculative picture may be consistent with the recent " ER = EPR " proposal for resolving the black hole entanglement debates.

    The Nearby Supernova Factory (SNfactory) is an international experiment designed to lay the foundation for the next generation of cosmology experiments (such as CFHTLS, wP, SNAP and LSST) which will measure the expansion history of the Universe using Type Ia supernovae. The SNfactory will discover and obtain frequent lightcurve spectrophotometry covering 3200-10000 {angstrom} for roughly 300 Type Ia supernovae at the low-redshift end of the smooth Hubble flow. The quantity, quality, breadth of galactic environments, and homogeneous nature of the SNfactory dataset will make it the premier source of calibration for the Type Ia supernova width-brightness relation and the intrinsic supernova colors used for K-correction and correction for extinction by host-galaxy dust. This dataset will also allow an extensive investigation of additional parameters which possibly influence the quality of Type Ia supernovae as cosmological probes. The SNfactory search capabilities and follow-up instrumentation include wide-field CCD imagers on two 1.2-m telescopes (via collaboration with the Near Earth Asteroid Tracking team at JPL and the QUEST team at Yale), and a two-channel integral-field-unit optical spectrograph/imager being fabricated for the University of Hawaii 2.2-m telescope. In addition to ground-based follow-up, UV spectra for a subsample of these supernovae will be obtained with HST. The pipeline to obtain, transfer via wireless and standard internet, and automatically process the search images is in operation. Software and hardware development is now underway to enable the execution of follow-up spectroscopy of supernova candidates at the Hawaii 2.2-m telescope via automated remote control of the telescope and the IFU spectrograph/imager.

  1. PEP-II: An asymmetric B factory

    International Nuclear Information System (INIS)

    In this report, the authors have described an updated conceptual design for the high-luminosity Asymmetric B Factory (PEP-II) to be built in the PEP tunnel culmination of more than four years of effort aimed at the design and construction of an asymmetric e+e- collider capable of achieving a luminosity of L = 3 x 1033 cm-2 s-1. All aspects of the conceptual design were scrutinized in March 1991 by a DOE technical review committee chaired by Dr. L. Edward Temple. The design was deemed feasible and capable of achieving its physics goals. Furthermore, the cost estimate, schedule, and management plan for the project were fully endorsed by the committee. This updated conceptual design report captures the technical progress since the March 1991 review and reflects the lower cost estimate corresponding to the improved design. Although the PEP-II design has continued to evolve, no technical scope changes have been made that invalidate the conclusion of the DOE review. The configuration adopted utilizes two storage rings, an electron ring operating at 9 GeV and a positron ring at 3.1 GeV, each with a circumference of 2200 m. The high-energy ring is an upgrade of the PEP storage ring at SLAC; all PEP magnets and most power supplies will be reused. The upgrade consists primarily of replacing the PEP vacuum chamber and RF system with newly designed versions optimized for the high-current environment of PEP-II. The low-energy ring will be newly constructed and will be situated atop the high-energy ring in the PEP tunnel.

    International Nuclear Information System (INIS)

    Viral factories are complex structures in the infected cell where viruses compartmentalize their life cycle. Rubella virus (RUBV) assembles factories by recruitment of rough endoplasmic reticulum (RER), mitochondria and Golgi around modified lysosomes known as cytopathic vacuoles or CPVs. These organelles contain active replication complexes that transfer replicated RNA to assembly sites in Golgi membranes. We have studied the structure of RUBV factory in three dimensions by electron tomography and freeze-fracture. CPVs contain stacked membranes, rigid sheets, small vesicles and large vacuoles. These membranes are interconnected and in communication with the endocytic pathway since they incorporate endocytosed BSA-gold. RER and CPVs are coupled through protein bridges and closely apposed membranes. Golgi vesicles attach to the CPVs but no tight contacts with mitochondria were detected. Immunogold labelling confirmed that the mitochondrial protein p32 is an abundant component around and inside CPVs where it could play important roles in factory activities.

    1995-07-01

    The primary task of a semiconductor factory is to produce integrated circuits of outstanding performance at a steeply declining cost per electronic function delivered. The semiconductor industry over the next decade will need to continue to drive costs down in order to maximize manufacturing productivity in the climate of rising product complexity, equipment cost, and risk. Historically the industry has concentrated on aggressive yield improvement and declining wafer fab cost per cm{sup 2} as the dominant factors for increasing productivity. To continue to be competitive, SEMATECH is extending its focus beyond cost per cm{sup 2} to the more total view of cost per function. SEMATECH is working toward a combination of solutions to meet their manufacturing challenges recognizing that no single solution will provide enough benefit to achieve the productivity gains end users expect. The {open_quotes}whole factory{close_quotes} view is a useful strategic planning tool for defining the future of manufacturing in the semiconductor industry. 3 figs.

  20. Black hole as a wormhole factory

    2015-12-01

    Full Text Available There have been lots of debates about the final fate of an evaporating black hole and the singularity hidden by an event horizon in quantum gravity. However, on general grounds, one may argue that a black hole stops radiation at the Planck mass (ħc/G1/2∼10−5 g, where the radiated energy is comparable to the black hole's mass. And also, it has been argued that there would be a wormhole-like structure, known as “spacetime foam”, due to large fluctuations below the Planck length (ħG/c31/2∼10−33 cm. In this paper, as an explicit example, we consider an exact classical solution which represents nicely those two properties in a recently proposed quantum gravity model based on different scaling dimensions between space and time coordinates. The solution, called “Black Wormhole”, consists of two different states, depending on its mass parameter M and an IR parameter ω: For the black hole state (with ωM2>1/2, a non-traversable wormhole occupies the interior region of the black hole around the singularity at the origin, whereas for the wormhole state (with ωM2<1/2, the interior wormhole is exposed to an outside observer as the black hole horizon is disappearing from evaporation. The black hole state becomes thermodynamically stable as it approaches the merging point where the interior wormhole throat and the black hole horizon merges, and the Hawking temperature vanishes at the exact merge point (with ωM2=1/2. This solution suggests the “Generalized Cosmic Censorship” by the existence of a wormhole-like structure which protects the naked singularity even after the black hole evaporation. One could understand the would-be wormhole inside the black hole horizon as the result of microscopic wormholes created by “negative” energy quanta which have entered the black hole horizon in Hawking radiation process; the quantum black hole could be a wormhole factory! It is found that this speculative picture may be consistent with the

En la mayoria de los casos implementando el metodo de volumen finito (MVF), con consideraciones de flujo no viscoso, con la implementacion de los modelos de dos ecuaciones para la solucion de las ecuaciones que rigen el flujo turbulento. Asi mismo, se utilizan tecnicas de optimizacion que se basan en la parametrizacion geometrica, el planteamiento de una funcion objetivo y en la disminucion del fenomeno de cavitacion. En el presente trabajo se presenta la optimizacion de un rodete de una turbina hidraulica tipo Francis modelo, considerando tres condiciones de carga (75%, 85% y 100%) a traves de la dinamica de fluidos computacionales (CFD) como parte de un analisis hidraulico para la modernizacion de una unidad de generacion de potencia. Se realiza la optimizacion del rodete de una turbina tipo Francis, mediante un analisis previo de CFD mediante el MVF, considerando los efectos viscosos del fluido y el modelo de turbulencia Sparlat-Allmaras; modelando el distribuidor y el rodete por separado. Posteriormente se realiza la generacion de un modelo parametrico del rodete y se configura la simulacion para la generacion de la base de datos. Finalmente se plantea una funcion objetivo para con ello obtener la geometria optima de los alabes del rodete. Los resultados se presentan en forma grafica donde se muestra la distribucion de presiones del rodete original y el rodete optimizado; de igual forma, se comparan las formas geometricas y los resultados globales de desempeno (potencia y rendimiento) de ambos rodetes.

    The construction and discontinuance processes of factories are complicated problems in sociology. We focus on the spatial and temporal changes of factories at Hamamatsu city in Japan. Real data indicate that the clumping degree of factories decreases as the density of factory increases. To represent the spatial and temporal changes of factories, we apply "contact process" which is one of cellular automata. This model roughly explains the dynamics of factory distribution. We also find "historical effect" in spatial distribution. Namely, the recent factories have been dispersed due to the past distribution during the period of economic bubble. This effect may be related to heavy shock in Japanese stock market.

    Full Text Available The rapid growth of industrial town and factories has paved the way to develop our industrial legislation accordingly. The Government of India never expressed their interest in framing separate legislation vis-à-vis factories which resulted in implementation of the same statute which was enacted pre-independence. It was done by virtue of Art. 372 of the Constitution of India. However, the Constitutional Lawmakers created vacuum for the implementation of new statute in accordance with the demand of society by inserting scope under the Directive Principles of State Policies. However, in the 67 years history of Indian Republic, there are unprecedented developments of law relating to factories in India.The Government of India, with the adoption of existed statute, made an effort to incorporate the welfare legislation but it never developed along with the change in time. It is to be noticed that as far as existing statutes are concerned, the development is an effect of judicial pronouncement or some tragic incident like Bhopal Gas Tragedy. This paper succinctly describes the history of factory legislation, the constitutional validity of the previous statute and necessary amendment which have already been done and / or on the verge of being amended. It will further discuss contribution of judiciary in developing the law relating to factories, scope of industrial jurisprudence in promoting the development of factory legislation. The primary focus of the research project is to reflect upon the areas where factory legislation has developed, so that proper yardstick could be made in order to put emphasis on those areas which have been remained untouched.

    Wind energy is nowadays one of the most cost-effective and practical options for electric generation from renewable resources. However, increased penetration of wind generation causes the power networks to be more depend on, and vulnerable to, the varying wind speed. Modeling is a tool which can provide valuable information about the interaction between wind farms and the power network to which they are connected. This paper develops a realistic characterization of a wind generator. The wind generator model is incorporated into an algorithm to investigate its contribution to the stability of the power network in the time domain. The tool obtained is termed dynamic power flow. The wind generator model takes on account the wind speed and the reactive power consumption by induction generators. Dynamic power flow analysis is carried-out using real wind data at 10-minute time intervals collected for one meteorological station. The generation injected at one point into the network provides active power locally and is found to reduce global power losses. However, the power supplied is time-varying and causes fluctuations in voltage magnitude and power flows in transmission lines. [Spanish] La energia eolica es hoy en dia una de las opciones mas efectivas y practicas para la generacion de electricidad a partir de energias renovables. Sin embargo, el incremento de la penetracion de energia eolica provoca que los sistemas de potencia se vuelvan mas dependientes y vulnerables a las variaciones de la velocidad del viento. El modelado es una herramienta que provee informacion valiosa de la interaccion dinamica entre las turbinas eolicas y las redes de potencia a las que se conectan. El presente articulo desarrolla una caracterizacion realista de un modelo de la turbina eolica. El modelo de la turbina eolica se incorpora a un algoritmo para el analisis de su contribucion a la estabilidad de una red electrica en el dominio del tiempo.

There are many environmental and occupational hazards in these factories.Objective: To evaluate the workplace environmental and occupational hazards in small household incense and joss stick factories in Roi-Et, Thailand.Methods: Nine small household factories in rural areas of Roi-Et, Thailand, were studied. Dust concentration and small aerosol particles were counted through real time exposure monitoring. The inductively coupled plasma optical emission spectrometry (ICP-OES was used for quantitative measurement of heavy metal residue in incense products.Results: Several heavy metals were found in dissolved dye and joss sticks. Those included barium, manganese, and lead. Rolling and shaking processes produced the highest concentration of dust and aerosols. Only 3.9 % of female workers used personal protection equipment.Conclusion: Dust and chemicals were major threats in small household incense and joss stick factories in Thailand. Increasing awareness towards using personal protection equipment and emphasis on elimination of environmental workplace hazards should be considered to help the workers of this industry.

  18. Factorial Schur functions and the Yang-Baxter equation

    Bump, Daniel; Nakasuji, Maki

    2011-01-01

    Factorial Schur functions are generalizations of Schur functions that have, in addition to the usual variables, a second family of "shift" parameters. We show that a factorial Schur function times a deformation of the Weyl denominator may be expressed as the partition function of a particular statistical-mechanical system (six vertex model). The proof is based on the Yang-Baxter equation. There is a deformation parameter $t$ which may be specialized in different ways. If $t=-1$, then we recover the expression of the factorial Schur function as a ratio of alternating polynomials. If $t=0$, we recover the description as a sum over tableaux. If $t=\\infty$ we recover a description of Lascoux that was previously considered by McNamara. We also are able to prove using the Yang-Baxter equation the asymptotic symmetry of the factorial Schur functions in the shift parameters. Finally, we give a proof using our methods of the dual Cauchy identity for factorial Schur functions. Thus using our methods we are able to give...

In addition to plant biomass hydrolysates, glycerol is of interest here, being available in amounts relevant for industrial scale bioprocesses due to increased production of biodiesel. The well characterised cell factory Saccharomyces cerevisiae exhibits a clear preference for glucose as a carbon source...... with relevant applications as cell factories (including Pichia spp. and Yarrowia lipolytica) and other less well characterized strains (e.g. Pachysolen tannophilus).

    We give an overview of wake fields and impedances in a proposed Super B project, which is based on extremely low emittance beams colliding at a large angle with a crab waist transformation. Understanding the effects that wake fields have on the beam is critical for a successful machine operation. We use our combined experience from the operation of the SLAC B-factory and DA{Phi}NE {Phi}-factory to eliminate strong HOM sources and minimize the chamber impedance in the Super B design. Based on a detailed study of the wake fields in this design we have developed a quasi-Green's function for the entire ring that is used to study bunch lengthening and beam stability. In particular, we check the stability threshold using numerical solutions of the Fokker-Plank equation. We also make a comparison of numerical simulations with the bunch lengthening data in the B- factory.

    The Neutrino Factory is a new concept for an accelerator that produces a high-intensity, high-energy beam of electron and muon neutrinos - the ultimate tool for neutrino oscillation studies and the only machine conceived up today that could help detect CP violation of leptons. The basic concept of the Neutrino Factory is the production of neutrinos from the decay of high-energy muons. Due to their short lifetime, these muons have to be accelerated very fast. Several new accelerator techniques, like a high-intenstiy proton linac, high-power targets, ionization cooling or recirculating muon linacs are required. This paper presents a snapshot of the accelerator design at CERN. Although some aspects of this European Neutrino Factory Scheme have been optimised for the CERN site, the basic principle is site-independent.

    The long-term prospects for fully exploring three-flavor mixing in the neutrino sector depend upon an ongoing and increased investment in the appropriate accelerator R\\&D. Two new concepts have been proposed that would revolutionize neutrino experiments, namely the Neutrino Factory and the Beta Beam facility. These new facilities would dramatically improve our ability to test the three-flavor mixing framework, measure \\textsl{CP} violation in the lepton sector, and perhaps determine the neutrino mass hierarchy, and, if necessary, probe extremely small values of the mixing angle $\\theta_{13}$. The stunning sensitivity that could be achieved with a Neutrino Factory is described, together with our present understanding of the corresponding sensitivity that might be achieved with a Beta Beam facility. In the Beta Beam case, additional study is required to better understand the optimum Beta Beam energy, and the achievable sensitivity.

  20. Factorial Moments in a Generalized Lattice Gas Model

    Wettig, T

    1994-01-01

    We construct a simple multicomponent lattice gas model in one dimension in which each site can either be empty or occupied by at most one particle of any one of $D$ species. Particles interact with a nearest neighbor interaction which depends on the species involved. This model is capable of reproducing the relations between factorial moments observed in high--energy scattering experiments for moderate values of $D$. The factorial moments of the negative binomial distribution can be obtained exactly in the limit as $D$ becomes large, and two suitable prescriptions involving randomly drawn nearest neighbor interactions are given. These results indicate the need for considerable care in any attempt to extract information regarding possible critical phenomena from empirical factorial moments.

    The application of new concepts for the energy analysis of industrial processes, which consider the thermal integration of the process equipment, not only allows to detect energy recovery potentials that cannot be visualized with the traditional treatment of energy diagnosis of individual equipment, allows in addition, to suggest changes in the operation of the process that, without modifying the production, result in the reduction of the consumption of energy by the services and fuel. The analysis of thermal integration is illustrated for the case of a sugar mill, detecting a reduction potential in the use of fuel oil of 75%, and a potential increase of electrical production by cogeneration of 41%, departing from the modification of the use of the steam available in the process, and of the change of operation parameters of operation in the evaporation section. [Spanish] La aplicacion de nuevos conceptos para el analisis energetico de procesos industriales, los cuales consideran la integracion termica de los equipos del proceso, no unicamente permiten detectar potenciales de recuperacion de energia que no se pueden visualizar con el tratamiento tradicional de diagnostico energetico de equipos individuales, permiten ademas, sugerir cambios en la operacion del proceso que, sin modificar la produccion, redundan en una reduccion del consumo de servicios y combustible. El analisis de la integracion termica se ilustra para el caso de un ingenio azucarero, detectandose un potencial de reduccion del uso de combustoleo de 75%, y un potencial de incremento de produccion electrica por cogeneracion de 41%, a partir de la modificacion del uso del vapor disponible en el proceso, y del cambio de parametros de operacion en la seccion de evaporacion.

    This article presents the methodology to generate the mesh model of the computer model of a blade by means of commands in the software of CFD Fluent, mainly in the fluid zone, since a mesh sensitivity analysis becomes too expensive in terms of human and computer resources. When geometry is too irregular, modifications are required in the mesh to avoid problems such as the divergence, instability in the solution and the dependency on the results of temperature, pressure, velocity, etc. Such is the case of a blade with internal cooling of the first stage of a gas turbine. The results are included of the generated mesh as well as of the thermal analysis of the blade. Additionally the results of temperature, pressure and velocity of the combustion gases and of the cooling air are shown. [Spanish] Este articulo presenta la metodologia para generar el mallado del modelo computacional de un alabe por medio de comandos en el software de CFD Fluent, principalmente en la zona del fluido, ya que un analisis de sensibilidad de malla se vuelve demasiado costoso en terminos de recursos humanos y computacionales. Cuando la geometria es demasiado irregular, se requiere de modificaciones en la malla para evitar problemas como son la divergencia, inestabilidad en la solucion y la dependencia de los resultados de temperatura, presion, velocidad, etc. Tal es el caso de un alabe con enfriamiento interno de la primera etapa de una turbina de gas. Se incluyen los resultados tanto de la malla generada como del analisis termico del alabe. Adicionalmente se muestran los resultados de temperatura, presion y velocidad de los gases de la combustion y del aire de enfriamiento.

    The long-term prospects for fully exploring three-flavor mixing in the neutrino sector depend upon an ongoing and increased investment in the appropriate accelerator R&D. Two new concepts have been proposed that would revolutionize neutrino experiments, namely the Neutrino Factory and the Beta Beam facility. These new facilities would dramatically improve our ability to test the three-flavor mixing framework, measure CP violation in the lepton sector, and perhaps determine the neutrino mass hierarchy, and, if necessary, probe extremely small values of the mixing angle {theta}{sub 13}. The stunning sensitivity that could be achieved with a Neutrino Factory is described, together with our present understanding of the corresponding sensitivity that might be achieved with a Beta Beam facility. In the Beta Beam case, additional study is required to better understand the optimum Beta Beam energy, and the achievable sensitivity. Neither a Neutrino Factory nor a Beta Beam facility could be built without significant R&D. An impressive Neutrino Factory R&D effort has been ongoing in the U.S. and elsewhere over the last few years and significant progress has been made towards optimizing the design, developing and testing the required accelerator components, and significantly reducing the cost. The recent progress is described here. There has been no corresponding activity in the U.S. on Beta Beam facility design and, given the very limited resources, there is little prospect of starting a significant U.S. Beta Beam R&D effort in the near future. However, the Beta Beam concept is interesting, and progress on its development in Europe should be followed. The Neutrino Factory R&D program has reached a critical stage in which support is required for two crucial international experiments and a third-generation international design study. If this support is forthcoming, a Neutrino Factory could be added to the Neutrino Community's road map in about a decade.

    . Estos aspectos han provocado que dichos sistemas operen con margenes de seguridad mas limitados y que su estabilidad tenga que ser analizada de una manera confiable y precisa. Tomando en cuenta los aspectos arriba mencionados, a medida que los sistemas electricos han tenido que operar en condiciones mas forzadas para satisfacer la demanda de la carga, los problemas de estabilidad de voltaje se han presentado con mayor frecuencia provocando serios disturbios y en algunos casos, hasta apagones totales. Ante la ocurrencia de estos problemas, el analisis de establidad de voltaje ha cobrado cada vez mayor importancia en los estudios de las companias suministradoras de energia electrica provocando con esto que se destinen mayores recursos para la investigacion de este fenomeno con el proposito de comprenderlo y desarrollar tecnicas y herramientas que permitan estudiarlo de una manera mas completa. El analisis modal es una de las mas recientes tecnicas en estado estable la cual, desde su aparicion ha tenido un gran auge debido a la valios y rapida informacion que proporciona, ademas de su facilidad de implementacion y el poco esfuerzo computacional que requiere. En este trabajo se realiza la evaluacion de la estabilidad de voltaje d eun sistema electrico real aplicando de manera conjunta la tecnica de analisis modal con otras tecnicas convencionales como las curvas P-V y V-Q. Se ilustra tambien la manera en que la distinta informacion obtenida de estas tecnicas se complementa para lograr un estudio de estabilidad de voltaje mas completo y representativo. Ademas de analizar la estabilidad de voltaje para las condiciones normales de operacion (caso base), se evaluan tambien tres distintas alternativas de compensacion reactiva capacitiva con objeto de mejorar el margen o distancia a la inestabilidad de voltaje del sistema. Los resultado obtenidos con cada una de las opciones de compensacion son analizados y comparados entre si para finalmente proponer la alternativa que presente

    In this article, I use a new book about Jean Piaget to introduce a new historical method: examining "psychological factories." I also discuss some of the ways that "Great Men" are presented in the literature, as well as opportunities for new projects if one approaches the history of the discipline differently and examines the conditions that made that greatness possible. To that end, the article includes many details about Piaget that have never before been discussed in English. Attention is drawn, in particular, to Piaget's collaborators: the hundreds of workers at his factory in Geneva, many of whom were women. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

    In design theory,the alias structure of regular fractional factorial designs is elegantly described with group theory.However,this approach cannot be applied to nonregular designs directly. For an arbitrary nonregular design,a natural question is how to describe the confounding relations between its effects,is there any inner structure similar to regular designs? The aim of this article is to answer this basic question.Using coefficients of indicator function,confounding structure of nonregular fractional factorial designs is obtained as linear constrains on the values of effects.A method to estimate the sparse significant effects in an arbitrary nonregular design is given through an example.

    There have been active efforts in the U.S., Europe, and Japan on the design of a neutrino factory. This type of facility produces intense beams of neutrinos from the decay of muons in a high-energy storage ring. In the U.S., a second detailed feasibility study (FS2) for a neutrino factory was completed in 2001. Since that report was published, new ideas in bunching, cooling, and acceleration of muon beams have been developed. We have incorporated these ideas into a new facility design, which we designate as study 2B (ST2B), that should lead to significant cost savings over the FS2 design.

    An analysis of a target factory leading to the determination of production expressions has provided for the basis of a parametric study. Parameters involving the input and output rate of a process system, processing yield factors, and multiple processing steps and production lines have been used to develop an understanding of their dependence on the rate of target injection for laser fusion. Preliminary results have indicated that a parametric study of this type will be important in the selection of processing methods to be used in the final production scheme of a target factory

    Full Text Available Abstrak : Abad ke-21 dapat disebut sebagai Abad Bahasa, mengingat kehidupan manusia dewasa ini tidak dapat dilepaskan dari pelbagai bentuk media massa. Akan tetapi, terkait dengan pengonstruksian fakta dan realitas, apalagi jika dilumuri oleh ego-sentris subjek-subjek di balik media massa tersebut, kerap terjadi bias pemberitaan yang memicu problem etis. Artinya, terjadi konspirasi di balik pemberitaan yang berdampak pada pengerdilan fungsi media massa sebagai wadah pendidikan politik bagi rakyat dalam kehidupan berbangsa dan bernegara. Demi membongkar konspirasi tersebut dibutuhkan metode analisis teks media yang baru, yang di dalam tulisan ini disebut metode analisis tindak tutur komunikasi. Metode ini dilahirkan secara hereustik, kritis, dan kontekstual melalui prinsip-prinsip kontemporer aliran Filsafat Bahasa Sehari-hari. Dengan demikian, metode ini selain hendak menegaskan bahwa komunikasi massa harus dilakukan secara etis dan emansipatoris, sekaligus hendak mengoreksi eksistensi metode analisis teks media lainnya yang selama ini sudah dikenal, namun tidak berdaya ketika harus membongkar konspirasi di balik pemberitaan media massa.Kata kunci : problem etis, metode analisis tindak tutur komunikasi, filsafat bahasa sehari-hari, analisis teks media. Abstract : The twenty-first century may be referred toas the century of language, considering how human life is inseparable from the various forms of mass media. However, concerning the construction of facts and reality, especially whenever mass-media becomes colored by ego-centric tendencies, biases in reporting frequently occur that raise ethical problems. It follows that there has been a conspiracy behind mass-media that has impact inobstructing the function of media as a forum for political education for the people. Therefore, in order to reveal the conspiracy a new media text analysis method -- which in this paper is called speech-act analysis method of communication -- is required. The

    In this paper are presented the results of the analysis of dynamic and thermodynamic behavior analysis of a turbo-blower integrated by one 13,080 KW steam turbine and a blower with a flow of 131,520 ft{sup 3}/m, to determine the cause of the excessive wearing of the axial trust bearing of the steam turbine. The main cause of failure is the wearing and severe dirtiness of the turbine stages that contributes with an increment of the turbine axial load. The consequences of the turbine deterioration are: greater axial load due to the additional heating rotor (requires greater steam to generate the same power that in design conditions); turbine motive power reduction and the reduction of isentropic efficiency of the same, for similar average steam consumption between reference and test. Due to the former the turbine power represents a deviation of the 34.74% in Steam Specific Consumption (SSC). [Spanish] Se presenta los resultados del analisis del comportamiento dinamico y termodinamico de un turbosoplador integrado por una turbina de vapor de 13,080 KW y un soplador con un caudal de 131,520 pies{sup 3}/m, para determinar la causa del desgaste excesivo de la chumacera de empuje axial de la turbina de vapor. La causa principal de la falla es el desgaste y ensuciamiento severo de las etapas de la turbina que contribuye con un incremento de la carga axial de la turbina. Las consecuencias del deterioro de la turbina son: mayor carga axial debida al calentamiento adicional del rotor (requiere mayor vapor para generar la misma potencia que en condiciones de diseno); reduccion de la potencia motriz de la turbina y de la eficiencia isoentropica de las mismas, para un consumo de vapor promedio similar entre referencia y prueba. Debido a lo anterior la potencia de la turbina representa una desviacion del 34.74% en el Consumo Especifico de Vapor (CVE).

    Four artificial intelligence tools developed at the Instituto de Investigaciones Electricas (IIE) to support the analysis of high tension insulator flaming are described. The first tool builds up a decision tree departing from historical data, the other 3 tools operate departing from the decision tree previously created to generate production rules, function as an expert system and make tests with many already known cases. These tools could predict the impending occurrence of flaming with enough time allowance for the insulators to be cleaned, since the traditional practice is the periodical cleaning of the insulators and this is not always adequate since the cleaning teams are limited, and the action of the environment is not always constant and for that reason insulators that do not need it are cleaned and vice-versa [Espanol] Se describen 4 herramientas de inteligencia artificial desarrolladas en el Instituto de Investigaciones Electricas (IIE) para apoyar al analisis de flameos en aisladores de alta tension. La primera herramienta construye el arbol de decision a partir de datos historicos; las otras 3 herramientas operan a partir del arbol de decision previamente creado para generar reglas de produccion, funcionar a la manera de un sistema experto y hacer pruebas con muchos casos conocidos. Estas herramientas podrian predecir la ocurrencia inminente del flameo con tiempo suficiente para que los aisladores se limpien, ya que la forma tradicional es limpiar periodicamente los aisladores y esto a veces no es adecuado debido a que las cuadrillas de limpieza son limitadas, ademas de que la accion del medio ambiente no es constante y es por eso que a veces se limpian aisladores que no lo necesitan o viceversa

    Full Text Available The national sugar production capability especially of the state owned sugar factory tends to decrease while demand increases.   To overcome the problem, government has issued the presidential Decree No. 5/2010 and declared a revitalization program of sugar industry as a priority development program. The Ministry of Industry has implemented the program by restructuring the sugar factory's machinery/equipments.  Since there are many of factories (51 units and the budget is limited, the ministry should be selective as to which factories need to be restructered, and therefore the program shoud be supported by prior information about the machinery efficiency status of each factory. To provide those information,  this study applies the application of the Overall Equipment Effectiveness (OEE method on 39 state owned sugar factories.  The results indicate that the everage rate of OEE for the 39 sugar factories for the year of 2010 to 2012 is 61.28% (best practice: 77.4%, while Availability, Performance, and Quality is 86.43%, 91.39%, and 77.02% respectively. The study also identifies 19 worst factories in efficiency, and therefore recommends those factories as priority to be restructured.

    Full Text Available ABSTRAKS   Informasi yang tidak sempurna dan tidak simetris mengakibatkan timbulnya ketidakpastian yang dihadapi konsumen tentang atribut dan/ atau manfaat apa yang didapat dari sebuah produk.  Dalam kondisi seperti ini penting bagi perusahaan untuk menyampaikan informasi terpercaya kepada konsumen, yaitu informasi yang jujur dan perusahaan harus bersedia dan mampu menyampaikan apa yang telah dijanjikan. Merek yang kredibel berpengaruh terhadap  kesan kualitas, resiko yang diterima dan biaya informasi. Kemudian kesan kualitas, resiko yang diterima dan biaya informasi akan mempengaruhi manfaat yang diharapkan.  Dan selanjutnya akan mempengaruhi sensitivitas harga konsumen. Populasi dalam penelitian ini adalah wanita dewasa yang berdomisili di kota Malang dan sampelnya adalah wanita berumur 17 sampai sengan 45 tahun yang menggunakan shampo Anti Ketombe dari satu atau lebih merek-merek yang sedang diteliti. Jumlah responden 100 orang dan metode pengambilan sampel yang digunakan adalah nonprobability sampling, dan teknik pengambilan sampel yang digunakan adalah quota sampling. Uji empiris menggunakan Metode Analisis Jalur. Hasil penelitian menunjukkan bahwa kredibilitas merek berpengaruh terhadap sensitivitas harga konsumen. Selain itu kredibilitas merek berpengaruh secara tak langsung terhadap sensitivitas harga konsumen melalui kesan kualitas dan manfaat yang diharapkan; Kredibilitas merek berpengaruh tak langsung terhadap sensitivitas harga konsumen melalui melalui biaya informasi dan manfaat yang diharapkan.

  8. Semi-factorial models and N\\'eron models

    CERN Document Server

    Pépin, Cédric

    2011-01-01

    Let S be the spectrum of a discrete valuation ring with function field K. Let X be a scheme over S. We will say that X is semi-factorial over S if each invertible sheaf on the generic fiber X_K can be extended to an invertible sheaf on X. Here we show that any proper geometrically normal scheme over K admits a model over S which is proper, flat, normal and semi-factorial. We also construct some semi-factorial compactifications of regular S-schemes, such as N\\'eron models of abelian varieties. Moreover, the semi-factoriality property for a scheme X/S corresponds to the N\\'eron property of its Picard functor. In particular, one can recover the N\\'eron model of the Picard variety of X_K from the Picard functor of X/S, as in the case of curves. This provides some information about relative algebraic equivalence on the S-scheme X.

    We consider the prospects for a neutrino factory measuring mixing angles, the CP violating phase and mass-squared differences by detecting wrong-charge muons arising from the chain {mu}{sup +} {yields} {nu}{sub e} {yields} {nu}{sub {mu}} {yields} {mu}{sup -} and the right-charge muons coming from the chain {mu}{sup +} {yields} anti {nu}{sub {mu}} {yields} anti {nu}{sub {mu}} {yields} {mu}{sup -} (similar to {mu}{sup -} chains), where {nu}{sub e} {yields} {nu}{sub {mu}} and anti {nu}{sub {mu}} {yields} anti {nu}{sub {mu}} are neutrino oscillation channels through a long baseline. First, we study physics with near detectors and consider the treatment of systematic errors including cross section errors, flux errors, and background uncertainties. We illustrate for which measurements near detectors are required, discuss how many are needed, and what the role of the flux monitoring is. We demonstrate that near detectors are mandatory for the leading atmospheric parameter measurements if the neutrino factory has only one baseline, whereas systematic errors partially cancel if the neutrino factory complex includes the magic baseline. Second, we perform the baseline and energy optimization of the neutrino factory including the latest simulation results from the magnetized iron neutrino detector (MIND). We also consider the impact of {tau} decays, generated by appearance channels {nu}{sub {mu}} {yields} {nu}{sub {tau}} and {nu}{sub e} {yields} {nu}{sub {tau}}, on the discovery reaches of the mass orderings, the leptonic CP violation, and the non-zero {theta}{sub 13}, which we find to be negligible for the considered detector. Third, we make a comparison of a high energy neutrino factory to a low energy neutrino factory and find that they are just two versions of the same experiment optimized for different regions of the parameter space. In addition, we briefly comment on whether it is useful to build the bi-magic baseline at the low energy neutrino factory. Finally, the

    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.

    criterio para juzgar la confiabilidad de un sistema electrico de potencia, es la frecuencia y duracion de la interrupcion del suministro de energia electrica a los consumidores. Debido a la importancia de mantener la continuidad del servicio de energia electrica, es necesario estudiar los dispositivos de proteccion contra sobretensiones, ya que en condiciones meteorologicas adversas, asi como por condiciones de cambio de configuracion en la red, se pueden presentar sobretensiones que danen a los equipos del sistema electrico de potencia. Los apartarrayos son dispositivos cuya funcion es proteger equipos de un sistema electrico de potencia contra las sobretensiones, por medio de absorcion de energia a traves del sistema de aterrizamiento. En la proteccion de los Sistemas Electricos de Potencia (SEP) contra sobretensiones comunmente se empleaban los apartarrayos de carburo de silicio (SiC) que brindaban un margen de proteccion pequeno. En los ultimos anos se han desarrollado nuevas tecnologias que han revolucionado la coordinacion del aislamiento. Un ejemplo de estas tecnologias es la aplicacion de los apartarrayos de oxidos metalicos (ZnO), los cuales incrementan el margen de proteccion considerablemente. En este trabajo se evaluan las limitaciones y potencialidades reales de los modelos existentes, y el propuesto en este trabajo, de apartarrayos de oxidos metalicos, con la ayuda de las simulaciones digitales en transitorios electromagneticos, cuando los apartarrayos estan sujetos a transitorios por maniobra de interruptores como por descargas atmosfericas. Todas las simulaciones en este trabajo se realizaron con el Programa de Transitorios Electromagneticos (EMTP), que es una herramienta ampliamente usada y recomendada para el analisis de los fenomenos transitorios electromagneticos. El modelado de los apartarrayos de oxidos metalicos en el EMTP es complicado por el comportamiento no lineal de sus elementos y se requiere de una gran precision y cuidado para implementar

    The importance of a super- factory in the search for new physics, in particular, due to CP-odd phase(s) from physics beyond the standard model is surveyed. The first point to emphasize is that we now know how to directly measure all three angles of the unitarity triangle very cleanly, i.e. without theoretical assumptions with irreducible theory error $\\lesssim 1$%. However, this requires much more luminosity than is currently available at -factories. Direct searches via penguin-dominated hadronic modes as well as radiative, pair-leptonic and semi-leptonic decays are also discussed. Null tests of the SM are stressed as these will play a crucial role especially if the effects of BSM phase(s) on -physics are small.

    The U.S. is addicted to petroleum--a dependency that periodically shocks the economy, compromises national security, and adversely affects the environment. If liquid fuels remain the main energy source for U.S. transportation for the foreseeable future, the system solution is the production of new liquid fuels that can directly displace diesel and gasoline. This study focuses on advanced concepts for biofuel factory production, describing three design concepts: biopetroleum, biodiesel, and higher alcohols. A general schematic is illustrated for each concept with technical description and analysis for each factory design. Looking beyond current biofuel pursuits by industry, this study explores unconventional feedstocks (e.g., extremophiles), out-of-favor reaction processes (e.g., radiation-induced catalytic cracking), and production of new fuel sources traditionally deemed undesirable (e.g., fusel oils). These concepts lay the foundation and path for future basic science and applied engineering to displace petroleum as a transportation energy source for good.

    The demand for an enhanced resource efficiency and energy efficiency in production arises not only from a purely economic perspective, but also from environmental and social reasons. Nevertheless, the issue of resource efficiency did not gain the necessary attention at the corporate level. In 2009, the Federal Ministry of Education and Research (Berlin, Federal Republic of Germany) launched a program to develop resource-efficient production technologies in which 31 integrated research projects with the efficiency factory and a dedicated accompanying project are promoted immediately in order to improve the transfer of the results. The contribution under consideration reports on the performance of the efficiency factory as a transfer platform in the context of the funding priority and the research results achieved up to now.

    2009-01-01

    The Neutrino Factory is an important tool in the long-term neutrino physics program. Substantial effort is put internationally into designing this facility in order to achieve desired performance within the allotted budget. This accelerator is a secondary beam machine: neutrinos are produced by means of the decay of muons. Muons, in turn, are produced by the decay of pions, produced by hitting the target by a beam of accelerated protons suitable for acceleration. Due to the physics of this process, extra conditioning of the pion beam coming from the target is needed in order to effectively perform subsequent acceleration. The subsystem of the Neutrino Factory that performs this conditioning is called Front End, its main performance characteristic is the number of the produced muons.

    The CERN Large Hadron Collider (LHC) requires constant monitoring and control of quantities of parameters to guarantee operational conditions. For this purpose, a methodology called UNICOS (UNIfied Industrial COntrols Systems) has been implemented to standardize the design of process control applications. To further accelerate the development of these applications, we migrated our existing UNICOS tooling suite toward a software factory in charge of assembling project, domain and technical information seamlessly into deployable PLC (Programmable logic Controller) – SCADA (Supervisory Control And Data Acquisition) systems. This software factory delivers consistently high quality by reducing human error and repetitive tasks, and adapts to user specifications in a cost-efficient way. Hence, this production tool is designed to encapsulate and hide the PLC and SCADA target platforms, enabling the experts to focus on the business model rather than specific syntaxes and grammars.

    The main goal of creation of a Superheavy Element Factory at the Flerov Laboratory of Nuclear Reactions (FLNR) is to sufficiently improve the efficiency of studies on heavy and superheavy nuclei. The factory will be based on a high-current DC-280 cyclotron. The use of beams with the intensity up to 6 ×1013 s-1 (10 pμA) requires effective separators providing high suppression of unwanted reaction products. Following the analysis of the kinematic characteristics of several hundreds of reactions, a conclusion was drawn that it is necessary to construct three separators optimized for specific tasks: a universal gas-filled separator for synthesis and study of the properties of heavy isotopes, a velocity filter for spectroscopic investigations, and a pre-separator for further chemical separation and precise mass measurements.

    Attention is focused on the implications of the Union Bargaining Model (UBM) for the factorial distribution of income. It is shown that when the contract curve is given, greater union bargaining power raises the wage share. We argue, however, that the factors that strengthen the bargaining power of unions are likely to induce offsetting shifts in the contract curve. A simulation exercise indicates that the shift in the contract curve is likely to be of secondary importance in determining the ...

  8. Optimized Neutrino Factory for small and large θ13

    International Nuclear Information System (INIS)

    Recent results from long baseline neutrino oscillation experiments point towards a non-zero value of θ13 at around 3σ confidence level. In the coming years, further ratification of this result with high significance will have crucial impact on the planning of the future long baseline Neutrino Factory setup aimed to explore leptonic CP violation and the neutrino mass ordering. In this talk, we discuss the baseline and energy optimization of the Neutrino Factory including the latest simulation results on the magnetized iron neutrino detector (MIND) in the light of both small and large θ13. We find that in case of small θ13, baselines of about 2500 to 5000 km is the optimal choice for the CP violation measurement with Eμ as low as 12 GeV can be considered. However, for large θ13, we show that the lower threshold and the backgrounds reconstructed at lower energies allow in fact for muon energies as low as 5 to 8 GeV at considerably shorter baselines, such as Fermilab to Homestake. This suggests that with the latest MIND simulation, low- and high-energy versions of the Neutrino Factory are just two different forms of the same experiment optimized for different regions of the parameter space.

    The Sloan Digital Sky Survey (SDSS) data handling presents two challenges: large data volume and timely production of spectroscopic plates from imaging data. A data processing factory, using technologies both old and new, handles this flow. Distribution to end users is via disk farms, to serve corrected images and calibrated spectra, and a database, to efficiently process catalog queries. For distribution of modest amounts of data from Apache Point Observatory to Fermilab, scripts use rsync to update files, while larger data transfers are accomplished by shipping magnetic tapes commercially. All data processing pipelines are wrapped in scripts to address consecutive phases: preparation, submission, checking, and quality control. We constructed the factory by chaining these pipelines together while using an operational database to hold processed imaging catalogs. The science database catalogs all imaging and spectroscopic object, with pointers to the various external files associated with them. Diverse computing systems address particular processing phases. UNIX computers handle tape reading and writing, as well as calibration steps that require access to a large amount of data with relatively modest computational demands. Commodity CPUs process steps that require access to a limited amount of data with more demanding computations requirements.

    With respect to a managing technology of advanced factories in the Japanese chemical industry, this paper enumerates the following three examples to discuss the ways the future factory technologies should be: operation techniques and problems in a newest ethylene plant, operation supports and facility control in chemical factories, and CIM structuring in beer breweries. The paper describes the operation techniques in an ethylene plant that are broken down into the following: measures for safety and material diversification, environment preservation, means to minimize the required labor, adoption of multi-variables, non-interference control technology for ethylene-propylene columns, and operation techniques that have been introduced with such a new technique as an integrated instrumentation room equipped with a gas leakage detection system. Structuring of CIM in the cited beer brewery has followed the transition of IE-TQC-JIT-FMS-CIM. Although a beer brewery may give somewhat different image from an ordinary chemical plant, the beer brewing process resembles a chemical plant in that it operates reacting machines in batch multiple tanks, and uses instrumentations and controllers using sensors. The key point in the future development is an organic link between market fluctuation and production activities. 1 fig.

  11. Infinite Factorial Unbounded-State Hidden Markov Model.

    There are many scenarios in artificial intelligence, signal processing or medicine, in which a temporal sequence consists of several unknown overlapping independent causes, and we are interested in accurately recovering those canonical causes. Factorial hidden Markov models (FHMMs) present the versatility to provide a good fit to these scenarios. However, in some scenarios, the number of causes or the number of states of the FHMM cannot be known or limited a priori. In this paper, we propose an infinite factorial unbounded-state hidden Markov model (IFUHMM), in which the number of parallel hidden Markovmodels (HMMs) and states in each HMM are potentially unbounded. We rely on a Bayesian nonparametric (BNP) prior over integer-valued matrices, in which the columns represent the Markov chains, the rows the time indexes, and the integers the state for each chain and time instant. First, we extend the existent infinite factorial binary-state HMM to allow for any number of states. Then, we modify this model to allow for an unbounded number of states and derive an MCMC-based inference algorithm that properly deals with the trade-off between the unbounded number of states and chains. We illustrate the performance of our proposed models in the power disaggregation problem. PMID:26571511

    2000-01-01

    A multi-laboratory collaboration is studying the feasibility of building a muon collider, the first phase of which maybe a neutrino factory. The phase space occupied by the muons is very large and needs to be cooled several orders of magnitude for either machine, 100,000 to 1 million for the collider and ten to 100 for the factory. Ionization cooling is the base line method for muon cooling. This scheme uses hydrogen absorbers and rf re-acceleration in a long series of magnetic focusing channels to cool the muons. At Fermilab two rf cavity types are under study to provide the required cooling rf re-acceleration, a 805 MHz high gradient cavity for the collider and a 201 MHz high gradient cavity for the neutrino factory. The 805 MHz cavity currently under going cold testing is a non-periodic pi-mode cavity with the iris openings shaped to follow the contour of the beam. The 201 MHz cavity uses hollow thin metal tubes over the beam aperture to terminate the field in a pill-box type mode to increase its shunt imp...

    In recent times every day one speaks more about power quality and about the losses produced by the tension and current distortion. The distortion in the electric network and the consumption tend to keep on increasing, and each day there will be the need of applying more resources to handle it inside a reasonable range. In this article the situation of the power quality is analyzed in the most general case and also simplified for special cases. On base on the distortion coefficients of tension and current a matrix is created where the harmonics coefficients of tension as well as the current appear in an organized form an all of the elements of that matrix are analyzed. Some topological rules are created in order to give the simplest orientation in the complex situation. The article is useful to supervise the power quality in all of the typical cases and establish a base for a more detailed analysis. [Espanol] En los ultimos tiempos cada dia mas se esta hablando sobre la calidad de la energia electrica (Power Quality) y sobre las perdidas provocadas con este factor.

En el articulo presentado se analiza la situacion de la calidad de energia en caso mas general y tambien simplificada para los casos especiales. A base de coeficientes de distorsion, de tension y corriente se crea una Matriz donde figuran tanto los coeficientes de armonicas de tension como de corriente en una forma ordenada y se analizan todos los elementos de esta matriz. Se crean algunas reglas topologicas para dar la orientacion mas simple en la situacion compleja. El articulo sirve para dar supervision a la calidad de energia en todos los casos tipicos y establecer una base para el analisis mas detallado.

    Full Text Available RDA appare come un ibrido: un elenco contenente un gran numero di elementi bibliografici e una riscrittura, formale più che sostanziale, delle pratiche di catalogazione stabilite con AACR2. Nel documento le linee guida vengono analizzate cercando di compararle con i requisiti che un buon codice di catalogazione dovrebbe possedere. Le regole di catalogazione non dovrebbero essere un modello astratto e auto-referenziale, ma uno strumento efficace per l'analisi e la rappresentazione dei fenomeni culturali, che serva ad apprendere ciò che è necessarioper gli utenti, e per il personale qualificato.Da questo punto di vista, il testo RDA è piuttosto deludente: molti gravi problemi di catalogazione e che si verificano di frequente non sono menzionati e la catalogazione è lasciata senza una reale linea guida. Un certo numero di lacune, errori e carenze individuati nel testo potranno essere modificati in futuro dalla redazione attraverso un'analisi approfondita delle reali attività di catalogazione.

    , los efectos capacitivos inherentes de la red, bajo ciertas condiciones, pueden producir un fenomeno conocido con el nombre de ferrorresonancia, el cual trae consigo la saturacion del material ferromagnetico de los transformadores, lo cual a su vez produce la aparicion de sobrevoltajes y altas corrientes de excitacion en forma de oscilaciones bastante distorsionadas que mas que transitorias, toman un verdadero estado estable, entendiendose por esto que las amplitudes alcanzadas se mantienen hasta que se tome una medida correctiva; tal situacion traera como consecuencia el dano irremediable del equipo electrico. Este trabajo esta encaminado a presentar al ambiente ingenieril la susceptibilidad de los sistemas electricos de potencia al problema de ferrorresonancia. Para ello se establece claramente la metodologia seguida para el analisis. Como el problema es de caracter no lineal se utilizan modelos que involucran la dinamica del sistema y el fenomeno de saturacion de los transformadores. Se proporcionan las tecnicas computacionales para la simulacion de las ferro-oscilaciones asi como un estudio completo desarrollado en laboratorio. Se hace una serie de recomendaciones a las redes de potencia electrica y a los fabricantes de transformadores del pais, con el fin de prevenir la ocurrencia del problema, debiendose tomar en cuenta estas principalmente en la fase de diseno.

    In this article is presented a solar refrigeration system that integrates the more recent and important technological advances of the training solar systems (SCS) and of the advanced absorption units. An analysis and evaluation is made of the energy behavior of the absorption system with heat exchanger absorber-generator (GAX), air cooled and assisted by a hybrid power plant natural gas-solar. Given the characteristic of high not-linearity of the resulting system of occupations, the proposed methodology contemplates a calculation sequence for the external currents and an iterative procedure for the internal currents. The unit was designed with a capacity of 10.6 kw (3 tons.) of cooling and uses ammonia-water as working fluid. Giving priority to internal energy integration, an arrangement of the GAX cycle is proposed, that allows 19% of solar contribution at full load, being able to be greater at partial loads. In spite of using as cooling means air at 40 Celsius degrees with a relative humidity of 24%, a COP of 0.86 in the cooling mode was obtained and 1.86 in the heating mode, with an internal energy integration of 1013 kJ/min, 37% more of the energy that is supplied in the generator. The massic flow rates of the GAX cycle were compared with those of a basic cycle, resulting 73% and 62% lower for the circulation rate and for the flow rate, respectively. [Spanish] En este articulo se presenta un sistema de refrigeracion solar que integra los avances tecnologicos mas recientes e importantes de los sistemas de capacitacion solar (SCS) y de las unidades de absorcion avanzadas. Se realiza un analisis y evaluacion del comportamiento energetico del sistema de absorcion con intercambio de calor absorbedor-generador (GAX), enfriado por aire y asistido por una fuente de energia hibrida gas natural-solar. Dada la caracteristica de alta no-linealidad del sistema de ocupaciones resultante, la metodologia propuesta contempla una secuencia de calculo para las corrientes externas

    BTEX are important environmental pollutants, harmful to human through respiratory inhalation, digestive tract and skin contact, and also have teratogenic, mutagenic and carcinogenic effects. BTEX were detected in multi-media to identify their distributions and assess their human health risk in a pesticide factory in Hebei province. Purge and trap GC-MS, adsorption/thermal desorption GC chromatography and the health risk assessment model were applied, and corresponding management measures were proposed. The results showed that BTEX existed in soil, dust, air, groundwater and wastewater. The concentration of BTEX in dust of the production area was 7.33 mg x kg(-1), in particular the concentration of toluene was 5.64 mg x kg(-1), exceeding the Canadian industrial land standard. Building three scenarios for working more than 10 years, 20 years and 30 years, the total non-carcinogens index was 4.19 x10(-3), 8.25 x 10(-3) and 1.22 x 10(-2), respectively, all lower than 1; the carcinogens index of benzene was 1.70 x 10(-7), 3.34 x 10(-7) and 4.92 x 10(-7), respectively, all lower than 10(-6). It indicated that there was no significant non-carcinogens and carcinogens hazard to workers inside the factory, but they might be exposed to more health risks if their work experience increase. Finally, recommendations for improving the environmental quality and personnel security in the factory were proposed based on the research results. PMID:24028020

    Toxic metals such as lead and cadmium are among the pollutants that are created by the metal production factories and disseminated in the nature. In order to study the quantity of cadmium pollution in the environment of the metal production factories, 50 saplings of the spruce species at the peripheries of the metal production factories were examined and the samples of the leaves, roots, and stems of saplings planted around the factory and the soil of the environment of the factory were studied to investigate pollution with cadmium. They were compared to the soil and saplings of the spruce trees planted outside the factory as observer region. The results showed that the quantity of pollution in the leaves, stems, and roots of the trees planted inside the factory environment were estimated at 1.1, 1.5, and 2.5 mg/kg, respectively, and this indicated a significant difference with the observer region (p factory was estimated at 6.8 mg/kg in the depth of 0-10 cm beneath the level of the soil. The length of roots in the saplings planted around the factory of metal production stood at 11 and 14.5 cm in the observer region which had a significant difference with the observer region (p pollution with cadmium in the region has been influenced by the production processes in the factory.

    Full Text Available Air pollution from cement factory is classified as one of the sources of air pollution. The control of the air pollution by addressing the wind field dynamics was the main objective of the paper. The dynamics of dispersion showed a three way flow which was calculated and explained accordingly. The 3D model showed good level of accuracy by determining field values of air deposited pollutants. Mean concentration of diffusing pollutants was shown to be directly proportional to the plume angular displacement. The 2D model explained the details of the wind field dynamics and proffers a solution which may be relevant in controlling air pollution from anthropogenic sources.

    Full Text Available Awalnya kesenian lengger digunakan dalam upacara-upacara ritual di pedesaan serta upacara-upacara yang berkaitan dengan kesuburan. Saat ini kesenian lengger lebih mengarah pada fungsi hiburan dan komersial. Hal ini membuat penari lengger rentan terhadap eksploitasi baik secara ekonomi maupun seksual. Pertanyaan penelitian ini adalah bagaimana bentuk pertunjukan lengger; bagaimana tanggapan masyarakat terhadap keberadaan penari lengger;  bagaimana bentuk eksploitasi yang dialami oleh penari lengger; dan apa respon penari lengger tentang tindakan eksploitasi itu. Metode penelitian yang digunakan adalah kualitatif, dengan analisis data interpretatif. Lokasi penelitian di desa Selanegara, Sumpiuh, Banyumas. Hasil penelitian menunjukkan bahwa ada beberapa unsur yang terkait dengan bentuk pertunjukan lengger, yaitu: pemain, gerak, iringan musik, tata rias dan busana, serta tempat pementasan. Citra negatif penari lengger biasanya diasosiakan dengan gerakan tari yang erotis sehingga dapat memancing pelecehan, seperti diraba, dicolek, dipeluk dan dicium oleh para pengibing. Bentuk eksploitasi ekonomi terjadi karena tuntutan ekonomi sehingga mendorong para penari mengeksploitasi tubuhnya untuk mendapatkan uang.  Perlakuan tidak senonoh dari penonton merupakan bagian dari resiko profesi yang harus dijalani. Fenomena ini diharapkan dapat mendorong masyarakat dan pemerintah untuk melindungi para pelaku kesenian dari tindakan eksploitasi.Originally lengger is performed in ceremonies and rituals in rural ceremonies associated with fertility. Currently the performance of lengger has more entertainment and commercial functions. This makes the dancers vulnerable to exploitation lengger both economically and sexually. The objectiveof this study is to explore the form of lengger show, forms of exploitation experienced by dancers lengger, and the responses of the lengger dancer towards exploitation.

    Cogeneration that is the joint production of two energy manifestations departing from a single energy source, appears as one of the more viable options to achieve the optimum utilization of the finite resources. In the last decades, in which the economic growth of Mexico has been tied to the generation and supply of electric power, the State has functioned as an organizer and director of the national system of electric power generation, although the participation of the private enterprise has been determining. We must take into account that in order to cover the future electricity needs of the national development, it will be required approximately 17 thousand additional MW, for which the private sector, among which the small and medium industry can be highlighted, will have the road opened to generate them, taking advantage of the changes in the Law and Rules for the Public Service of Electric Power, published in the Diario Oficial de la Federacion on December 23, 1992 and on May 31, 1993. In having an optimized co-generation system, the annual cost for the plywood factory for energy (electricity and fuel) will be substantially reduced. The plywood factory requires the installation of a co-generation system that supplies 4.75 MWe and 1,861 KWt (1.6 Gcal/hr). The electric power will be used in the manufacture of NOVOPAN (Plywood) Panels and the thermal energy to heat up the thermal oil utilized in the wood press and for the preparation of the emulsion used in the process. To satisfy the energy requirements two options have been analyzed: Electric power generation with an internal combustion motor using fuel oil as fuel, utilizing the exhaust gases from the motor to preheat the thermal oil in a heat exchanger exhaust gases-thermal oil. Due to the fact that the motor exhaust gases do no contain enough energy to heat up the thermal oil at the desired temperature, a thermal fluid boiler burning wood wastes and tree barks will be used. Electric power generation with a
