    Full Text Available La producción académica ha aumentado en el área de la salud, exigiendo cada vez más calidad en las publicaciones de gran impacto. Una de las formas de considerar la calidad es por medio de procedimientos que aumentan la consistencia del análisis de los datos, como la confiabilidad, que dependiendo del tipo de datos, puede ser evaluada por diferentes coeficientes, en especial el coeficiente alfa. Basados en lo anterior, la presente revisión reúne sistemáticamente artículos científicos producidos en los últimos cinco años, que de manera metodológica hicieron uso psicométrico del coeficiente α como un estimador de consistencia interna y de confiabilidad en procesos de construcción, adaptación y validación de instrumentos. La identificación de los estudios fue realizada sistemáticamente en las bases de datos Biomed Central Journals, Google Scholar, Web of Science, Wiley Online Library, Medline via Pubmed, Scielo, Scopus, Journals@Ovid, BMJ y Springer por medio del Portal de Periódicos CAPES, utilizando criterios de inclusión y exclusión. El análisis de los datos fue realizado por medio de triangulación, análisis de contenido y análisis descriptivo. Se obtuvo que la mayoría de los estudios fueron realizados principalmente en Irán (f=3, España (f=2 y Brasil (f=2, estos estudios tuvieron como objetivo testar las propiedades psicométricas de instrumentos, siendo que ocho estudios utilizaron el coeficiente α para evaluar la confiabilidad y nueve para evaluar la consistencia interna. Todos los estudios fueron clasificados como investigaciones metodológicas al analizar sus objetivos. Adicionalmente, cuatro estudios también fueron clasificados como correlacionales y uno como descriptivo-correlacional. Se puede concluir que a pesar de que el coeficiente α es ampliamente utilizado como uno de los principales parámetros para la evaluación de consistencia interna de instrumentos de medición del tipo cuestionario en el

    Full Text Available En el presente artículo estudiamos las propiedades psicométricas de una escala breve (RL-14 creada con el objetivo de detectar la información / formación recibida por los empleados, así como las patologías psicofisiológicas. Los participantes de la presente investigación son 1.489 empleados de diversos sectores como la formación, la construcción, el transporte, la sanidad, la industria, el comercio y la hostelería. Los resultados obtenidos demuestran, después de realizar análisis factorial tanto exploratorio como confirmatorio, una estructura constituida por dos factores: "(F1 Información y Formación" y "(F2 Patologías Psicofisiológicas". Además, los dos factores obtenidos tienen una fiabilidad adecuada e igualmente se constatan indicios de validez de los dos factores si se toman como referencia algunas variables sociodemográficas, la fatiga, el burnout y la tensión laboral. En suma, la presente escala puede resultar idónea para identificar de manera apropiada los riesgos laborales. Futuras investigaciones podrían utilizar el RL-14 como una herramienta de screening en combinación con otros instrumentos.

Estudio de consistencia interna y reproducibilidad de tecnología diagnóstica. Ciento nueve sujetos entre 18 y 60 años respondieron en dos ocasiones a CAGE y a una encuesta sobre variables biol6gicas, sociodemográficas y de dieta. La consistencia interna de CAGE se evalu6 con el alfa de Cronbach y la reproducibilidad con el coeficiente de Spearman y el valor kappa de Cohen. Con regresión binomial obtuvimos medidas de asociación entre el riesgo de alcoholismo y las variables biológicas, sociodemográficas y de dieta. Resultados. El riesgo de alcoholismo para la población estudiada fue de 15,6% (IC, 9,0, 22,5. Los hombres presentaron un riesgo aumentado de alcoholismo tres veces mayor que las mujeres (p=0,02. El coeficiente alfa de Cronbach fue bajo para todas las preguntas de CAGE (mínimo, 0,08; máximo, 0,28. En la primera aplicación de CAGE se obtuvo un alfa de Cronbach de 0,20, y en la segunda, de 0,27 (p=0,226. El coeficiente de correlaci6n de Spearman fue de 0,65 (IC, 0,53, 0,75 para la población; de 0,58 (IC, 0,36, 0,73 para hombres, y de 0,80 (IC, 0,68, 0,88 para mujeres. Los valores de kappas alcanzados están entre moderados y buenos. Ninguna variable biológica, sociodemográfica o de dieta se asoció con el riesgo de alcoholismo. Conclusión. La baja consistencia interna de CAGE es debida a la multidimensionalidad de la prueba; dada su reproducibilidad y estabilidad de las medidas de asociación derivadas, es útil en la investigación epidemiológica en esta población.

    2011-01-01

    After a brief introductory chapter, "Factory Physics 3/e" is divided into three parts: I - The Lessons of History; II - Factory Physics; and III - Principles in Practice. The scientific approach to manufacturing and supply chain management, developed in Part II, is unique to this text. No other text or professional book provides a rigorous, principles-based foundation for manufacturing management. The Third Edition offers tighter connections between Lean Manufacturing, MRP/ERP, Six Sigma, Supply Chain Management, and Factory Physics. In addition to enhancing the historical overview of how these systems evolved, the authors show explicitly how users can achieve Lean Manufacturing objectives (faster response, less inventory) using the integration aspects of MRP/ERP/SCM systems along with the variance analysis methods of Six Sigma. Factory Physics provides the overarching framework that coordinates all of these initiatives into a single-focused strategy.

    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.

Los participantes fueron 1291 individuos distribuidos proporcionalmente según sexo (51% mujeres; 49% varones con edades entre 18 y 89 años (M = 38.9, DE = 16.49. Se llevaron a cabo estudios de validación cruzada e invarianza factorial para examinar si un modelo de siete factores que se correspondía con siete escalas clínicas (Hipersensibilidad, Obsesiones-Compulsiones, Ansiedad, Hostilidad, Somatización, Depresión, y Alteraciones del sueño presentaba un ajuste adecuado y un funcionamiento similar en muestras diferenciadas según sexo y edad de los evaluados. Esta estructura heptafactorial exhibió un buen ajuste en las cuatro submuestras. Tras analizar simultáneamente el ajuste en las submuestras mencionadas a través de modelos jerárquicos en los que se impusieron distintas restricciones de igualdad, se arribó a resultados que indicaron la invarianza de las siete dimensiones del LSB-50. El cálculo de alfas ordinales indicó un buen nivel de consistencia interna para todas las escalas. Finalmente, las correlaciones con una medida externa de diagnóstico de psicopatología -el Personality Assessment Inventory (PAI; Morey, 2007- indicaron, tal como se esperaba, una convergencia moderada. Se concluye que los análisis realizados proveen de contundentes evidencias de validez sobre los resultados arrojados por el LSB-50.

    Kaon factories would provide beams 100-1000 times more intense than those available from present accelerators in the 10-30 GeV range. More intense or cleaner secondary beams of kaons, antiprotons and neutrinos would be of particular interest for high precision experiments and studies of rare processes in both particle and nuclear physics, e.g. symmetry violations in K-decay, neutrino scattering, meson and baryon spectroscopy, hypernuclei, exotic atoms, K + studies of nuclear density and resonance propagation in nuclei. The various accelerators proposed include both fast-cycling synchrotrons providing 100 μA proton beams at 15 to 32 GeV and superconducting isochronous ring cyclotrons giving 100-400 μA at up to 15 GeV. This paper describes these designs and the various technical problems associated with them

Pese a su amplia utilización, su estructura teórica inicial no ha sido confirmada completamente, debido a que se han encontrado otro tipo de soluciones factoriales distintas a las 6 dimensiones propuestas por la autora. Estas divergencias podrían estar relacionadas al tipo de muestras y poblaciones utilizadas. Ante esto, la siguiente investigación compara el ajuste factorial de los modelos tradicionalmente aplicados de corrección en distintos grupos en edad adulta. Se describen las propiedades psicométricas de la adaptación al español realizada por Díaz et al. (2006, analizando los niveles de confiabilidad (consistencia interna y estabilidad temporal y estructura factorial confirmatoria, en datos de 1646 personas entre 18 y 90 años de edad. Se encuentran diferencias en los indicadores de confiabilidad para la escala total y las dimensiones, así como en los indicadores de bondad de ajuste dependiendo del grupo de edad. El modelo que presenta mejores indicadores de ajuste en la mayoría de los rangos etarios evaluados fue el de seis factores de primer orden.The scale of psychological well-being arises from the multidimensional model proposed by Ryff (1989. Despite its wide use, its initial theoretical structure has not been completely confirmed because other factorial solutions which are different from those 6 dimensions proposed by the author have been found. These differences may be related to the type of sample and population used. Given this fact, the current study compares the adjustment factor of correction models traditionally used in different groups of adults. We describe the psychometric properties of the Spanish adaptation done by Díaz et al.

Basado en este modelo teórico, se desarrolló el Sexual Excitation/Sexual Inhibition Inventory for Women (SESII-W, que permite la evaluación de las dimensiones excitación/inhibición sexuales en mujeres. El objetivo fue adaptar y validar el SESII-W en población española. Método: Una muestra de 1.380 mujeres heterosexuales (edad 18-52 años completó el SESII-W junto con otros cuestionarios afines. Después de la traducción y adaptación lingüística se realizó un Análisis Factorial Confirmatorio (AFC. Resultados: El AFC dio lugar a una versión de 33 ítems organizados en ocho subfactores, agrupados en dos factores de orden superior (Excitación Sexual e Inhibición Sexual. Los subfactores muestran aceptables valores de consistencia interna a excepción de Dinámicas sexuales de poder y Preocupaciones por el funcionamiento sexual. La fiabilidad test-retest fue aceptable. Sus puntuaciones correlacionaron en la dirección esperada con erotofilia, búsqueda de sensaciones, edad de la primera relación sexual y número de parejas sexuales.

El índice reológico estuvo en el rango de 0,0856 y 0,3131 (n < 1, el índice de consistencia “k” en el rango de 84,55 y 167,80 Pa.sn, esfuerzo de corte inicial en el rango de 9,10 y 13,51Pa y la consistencia sensorial presentó calificaciones de “me gusta” a “me gusta ligeramente”. Finalmente, se optimizó la mezcla de hidrocoloides sobre la zona de formulación factible. Con la mezcla óptima, correspondiente a: 0,28% CMC; 0,13% goma guar y 0,59% goma xantana se espera obtener una sinéresis de 0,089% y una calificación de 6 “me gusta ligeramente” en cuanto a la consistencia sensorial.

    Nowadays we live in a world, which a decade ago would only be described in the science fiction literature. More and more things become smart and both scientists and engineers strive for developing not only new and innovative devices, but also homes, factories, or even cities. Despite of continuous...... development, many of those concepts are still being just a vision of the future, which still needs a lot of effort to become true. This paper reviews the usage of adjective smart in respect to technology and with a special emphasis on the smart factory concept placement among contemporary studies. Due...... to a lack of a consensus of common understanding of this term, a unified definition is proposed. The conceptualization will not only refer to various smart factory visions reported in the literature, but also link the crucial characteristics of this emerging manufacturing concept to usual manufacturing...

    1990-04-01

    There are approximately 50,000 workers employed in the light assembly industry in Haiti. About 70% are women, the majority of whom are aged between 25 and 34 years, and are either single or in a nonpermanent relationship with the father of their children. Many live and work in appalling conditions, surviving on very low wages to support several children and an extended family. The acquired immunodeficiency syndrome (AIDS) is now a visible problem in many factories. In October 1988, the Center for the Promotion of Women Workers (Centre de Promotion des Femmes Ouvriers/CPFO) launched a pilot AIDS education program for factory women. The Center, based in a large industrial zone near the airport, runs a health clinic and courses in literacy, communications skills, health promotion and family planning. The new AIDS program allowed CPFO staff to gain entry into factories for the 1st time. Other courses were held outside working hours and outside factory premises. Staff contacted manages by telephone to arrange a meeting to discuss AIDS and to ask permission to hold educational "round tables" with workers. Of 18 managers in the factories approached over a 12-month period, only 2 refused entry to CPFO staff. Almost all managers reported they had registered between 2 and 5 deaths from AIDS among their employees over the past couple of years. A total of 85 educational sessions, each lasting about 2 hours, were held within 28 different factories, community or labor organizations reaching 3063 workers (male and female). In each session, the presentation was carried out by 2 CPFO trained monitors and included a slide show, flip charts, and the video "Met ko," originally produced for Haitian immigrants in New York. The most important aspect of the program was the training of 38 volunteer factory-based health promoters. These promoters attended the round table sessions, where they facilitated discussion and distributed condoms and were subsequently available for counseling co

Como parte de dicho proceso de análisis de puestos, se realizaron entrevistas de análisis de las tareas representativas de cada puesto. Los trabajadores entrevistados aportaron un total de 1.410 enunciados de destrezas mentales y 1.344 de relación. Para racionalizar dicha información se elaboró, en base a criterios de similitud semántica, una propuesta de 94 enunciados de destrezas mentales y 65 de relación. Así se redujo el número de enunciados sin pérdida de significado. El objeto de este estudio es comprobar la consistencia semántica de estos 94 y 65 enunciados propuestos a partir del grado de acuerdo de 5 expertos en Recursos Humanos con dicha propuesta. Para calcular dicho acuerdo se utiliza el Content Validity Ratio (CVR de Lawshe (1975. El análisis de estos datos ha permitido identificar cuáles de estos 94 y 65 enunciados propuestos mantener, modificar o eliminar. Como resultado se obtienen 30 enunciados de destrezas mentales y 26 de relación. Estos enunciados finales serán la base de estudios posteriores, cuyo objetivo será identificar la estructura factorial y desarrollar una taxonomía de las destrezas mentales y de relación de los trabajadores de la Administración General del País Vasco.

    The fourth industrial revolution promises to create what has been called the smart factory. The vision is that within such modular structured smart factories, cyber-physical systems monitor physical processes, create a virtual copy of the physical world and make decentralised decisions. This paper provides a view of this initiative from an automation systems perspective. In this context it considers how future automation systems might be effectively configured and supported through their lifecycles and how integration, application modelling, visualisation and reuse of such systems might be best achieved. The paper briefly describes limitations in current engineering methods, and new emerging approaches including the cyber physical systems (CPS) engineering tools being developed by the automation systems group (ASG) at Warwick Manufacturing Group, University of Warwick, UK.

    EMIR (Espectrógrafo Multiobjeto Infrarrojo) is a wide-field, near-infrared, multi-object spectrograph, with image capabilities, which will be located at the Nasmyth focus of GTC (Gran Telescopio Canarias). It will allow observers to obtain many intermediate resolution spectra simultaneously, in the nIR bands Z, J, H, K. A multi-slit mask unit will be used for target acquisition. This paper shows an overview of EMIR Data Factory System which main functionality is to receive raw images from DAS (Data Acquisition system), collect FITS header keywords, store images to database and propagate images to other GCS (GTC Control System) components to produce astronomical data. This system follows the standards defined by the telescope to permit the integration of this software on the GCS. The Data Factory System needs the DAS, the Sequencer, GUI and the Monitor Manager subsystems to operate. DAS generates images and sends them to the Data Factory. Sequencer and GUI (Graphical User Interface) provide information about instrument and observing program. The Monitor Manager supplies information about telescope and instrument state.

    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.

En el primer caso, los inversionistas minimizan la varianza del rendimiento de los activos de un portafolio sujeto a un rendimiento esperado. En el segundo caso, los consumidores maximizan utilidad por el consumo de un bien sujeto a una restricción presupuestal que incorpora los activos disponibles en la economía. La consistencia entre ambos postulados se muestra de la siguiente manera: en un ambiente de riesgo generado por activos, cuyos precios son conducidos por procesos de difusión, los dos postulados son utilizados para valuar una opción europea. El resultado principal es que en ambos casos se obtiene la misma ecuación diferencial parcial que caracteriza el precio de la opción, la cual coincide con la ecuación diferencial parcial de Black-Scholes-Merton (1973.

  10. SRF for neutrino factories

    Padamsee, H.

    2003-01-01

    The Neutrino Factory calls for nearly 500 meters of 200 MHz SRF cavities to provide 7.5 GV. Such a facility is more demanding than the largest SRF installation to date, i.e., LEP-II, where 500 m of niobium-coated copper cavities provided more than 3 GV of acceleration. Based on the high real estate gradient desired to minimize muon loss, superconducting cavities are selected to provide active gradients of 15 - 17 MV/m, and a real estate gradient of 7.5 MV/m. At such high gradients, the peak RF power demand for copper cavities would become prohibitively expensive. By virtue of low losses, SC cavities can be filled slowly (rise time 3 ms) reducing the peak power demand to roughly half MW per cell. (author)

    Hyperostosis frontalis interna is a morphological pattern characterized by single or multiple bony nodules situated on the inner lamina of the frontal bone. It is seldom found in males, but it is a common phenomenon among post-menopausal females in modern societies but relatively rare in antiquity. The etiopathogenesis of the trait is a matter of debate and ranges from genetic predisposition to epigenetic, while endocrine disturbances, aging, and dietary factors are also listed among the causes. We studied the frequency, characteristic features, and etiopathogenesis of the disease in recent cadaveric and dry skull specimens. The frequency of hyperostosis frontalis interna in cadavers and dry skull materials was almost identical, 12.5% and 12.3%, respectively. In cadavers, 87.5% of severe hyperostosis frontalis interna cases were found in females over 65 years-old. Interestingly, in two cadavers we found hyperostotic lesions spreading onto adjacent tissues such as the dura and falx cerebri. We provide some new aspects that may help in better understanding of the etiopathogenesis of hyperostosis frontalis interna. Thereby, we discuss the various etiopathogenesis models found in the literature. Copyright © 2011 Elsevier GmbH. All rights reserved.

    Full Text Available El TCI-R es el más reciente instrumento de medida de la teoría biosocial de Cloninger y se ha mostrado como uno de los cuestionarios más útiles en la predicción de la conducta, especialmente en sus variantes patológicas. A pesar de que la versión española fue publicada hace siete años apenas contamos con estudios que avalen su bondad psicométrica. Se requiere conocer la fiabilidad y validez interna para su aplicación clínica. Se reclutó una muestra de 824 participantes que inician tratamiento por su adicción en un centro específico. Se realizaron pruebas de consistencia interna sobre los ítems, las subescalas y las dimensiones principales del cuestionario y se estudió la validez de constructo mediante análisis factoriales exploratorio multivariado, paralelo y confirmatorio. Los resultados evidenciaron diversas inconsistencias en los diferentes niveles de análisis, si bien la tendencia principal apunta a la confirmación de la estructura teórica. Teniendo en cuenta la validez predictiva mostrada por el TCI-R, se hace necesario un refinamiento que reafirme su valor clínico. Quizá, como sugiere el propio Cloninger, sea necesario utilizar metodologías no-lineales, que capten las relaciones dinámicas entre los sustratos neurológicos que subyacen a los rasgos y un concepto menos estático de los componentes de la personalidad.

    The Nearby Supernova Factory (SNfactory) is an ambitious project to find and study in detail approximately 300 nearby Type Ia supernovae (SNe Ia) at redshifts 0.03 < z < 0.08. This program will provide an exceptional data set of well-studied SNe in the nearby smooth Hubble flow that can be used as calibration for the current and future programs designed to use SNe to measure the cosmological parameters. The first key ingredient for this program is a reliable supply of Hubble-flow SNe systematically discovered in unprecedented numbers using the same techniques as those used in distant SNe searches. In 2002, 35 SNe were found using our test-bed pipeline for automated SN search and discovery. The pipeline uses images from the asteroid search conducted by the Near Earth Asteroid Tracking group at JPL. Improvements in our subtraction techniques and analysis have allowed us to increase our effective SN discovery rate to ∼12 SNe/month in 2003

    Rapid advances in service robotics together with dramatic shifts in population demographics have led to the notion that technology may be the answer to our eldercare problems. Robots are being developed for feeding, washing, lifting, carrying and mobilising the elderly as well as monitoring their health. They are also being proposed as a substitute for companionship. While these technologies could accrue major benefits for society and empower the elderly, we must balance their use with the ethical costs. These include a potential reduction in human contact, increased feeling of objectification and loss of control, loss of privacy and personal freedom as well as deception and infantilisation. With appropriate guidelines in place before the introduction of robots en masse into the care system, robots could improve the lives of the elderly, reducing their dependence and creating more opportunities for social interaction. Without forethought, the elderly may find themselves in a barren world of machines, a world of automated care: a factory for the elderly. Copyright © 2011 S. Karger AG, Basel.

    The TRIUMF KAON Factory is designed to produce beams of kaons, antiprotons, other hadrons and neutrinos 100 times more intense, or cleaner, than are available now, for a broad range of experiments in particle and nuclear physics. This will require a 100 μA beam of 30 GeV protons, to be produced by an interleaved sequence of two fast-cycling synchrotrons and three storage rings, with the existing TRIUMF H - cyclotron as injector. An $11-million preconstruction study has enabled the overall design to be reviewed and prototypes of various accelerator components to be built and evaluated. Environmental, industrial and economic impact studies have also been completed. Payment of one-third of the total cost of $708 million (Canadian) has been approved by the government of British Columbia; a further third is expected from international sources, on the basis of inter-governmental consultations.

The adecuacy of the performance of these tasks is dificult to mea sure because there is no correct way to do them due to individual differences. One way to measure these differences is to calculate the degree of consistence with which the same and different indexers carry out the se processes. The aim is to evaluate the inter-indexer consistency in the selection of documents to be included in the third volume of the repertoire Documentación Médica Española (1996 and in the asignation of the main cathegory of the classification and to analize the causes of discrepancies. The new selection and re-indexing of the material has been carried out by an external indexer with expertise in the field. 370 documents have been reselected. The re-indexed documents have been those where both indexers agree that were relevants. To measure consistency the agreement proportion between indexers was calculated. The agreement proportion for the selection of the material was 86 % and for the assignation of the main cathegory of the classification was 78.6 %. The analysis of the discrepancies has showed an high degree of consistency for documents that deal with central topics of the field. Indexing discrepancies are mainly due to errors of both indexers, exemption made of a small group of documents of similar contents.

    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 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.

  4. AutoPyFactory: A Scalable Flexible Pilot Factory Implementation

    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.

  16. Possible experiments at neutrino factories

    CERN Document Server

    Niinikoski, T O

    2001-01-01

    There are currently plans to construct neutrino factories based on muon storage rings. Such projects are parts of large programmes for the production, cooling, acceleration and storage of muons for dedicated muon colliders, and the lower-energy neutrino factories are perceived as a first step towards the colliders at a much higher energy. We shall explore possible experiments at the projected high- intensity neutrino beams. Among these experiments the measurement of the nuclear coherent scattering cross section would be based on the use of thermal calorimetric detectors segmented so that self-vetoing would supplement the surrounding veto detectors.

  17. Corynebacterium pseudotuberculosis associated with otitis media-interna in goats

    2013-08-01

    Full Text Available Corynebacterium pseudotuberculosis or caseous lymphadenitis is a common condition in sheep and goats. Two cases are described involving otitis media-interna and, in one case, cerebellar abscessation. The first case began with otitis externa and progressed to cerebellar abscessation, presumably as a result of C. pseudotuberculosis infection based on the macroscopic appearance of the abscess. The second case of otitis media-interna involved C. pseudotuberculosis with parasitic encephalitis or secondary meningo-encephalitis. Caseous lymphadenitis is a worldwide problem in livestock and also has zoonotic implications. Antimicrobial therapy of abscesses is often unrewarding due to the thick encapsulation of the abscesses and the extremely contagious nature of the organism. Alternative measures of treating this condition must be sought. In flocks or herds where caseous lymphadenitis has been diagnosed, it should be considered as a differential diagnosis for neurological conditions. The potential for spread must be kept in mind when it is suspected to be the cause of otitis in livestock.

    Full Text Available Resumen Este texto constituye una propuesta teórica sobre la dimensión expresiva del habla interna. Se describe el fenómeno de interés enfatizando la propuesta de Karl Bühler respecto a la expresividad del lenguaje, los estudios de Heinz Werner sobre una dimensión fisionómica-organísmica del lenguaje humano y la aproximación teórico-empírico de Lev Vygotsky respecto al fenómeno del habla interior en la experiencia humana. Se concluye que en algunos pasajes de la obra de Vygotsky están las claves para una comprensión del habla interna expresiva, específicamente en la influencia de la esfera afectivo-volitiva en el desarrollo del pensamiento y de la palabra. Finalmente, se propone una integración de la concepción monológica vygotskyana del lenguaje interior, la noción werneriana del lenguaje fisionómico-organísmico y la propuesta bühleriana de la dimensión expresiva del lenguaje humano, para una comprensión integradora de la expresividad del lenguaje interior.

    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)

  10. MUON STORAGE RINGS - NEUTRINO FACTORIES

    International Nuclear Information System (INIS)

    PARSA, Z.

    2000-01-01

    The concept of a muon storage ring based Neutrino Source (Neutrino Factory) has sparked considerable interest in the High Energy Physics community. Besides providing a first phase of a muon collider facility, it would generate more intense and well collimated neutrino beams than currently available. The BNL-AGS or some other proton driver would provide an intense proton beam that hits a target, produces pions that decay into muons. The muons must be cooled, accelerated and injected into a storage ring with a long straight section where they decay. The decays occurring in the straight sections of the ring would generate neutrino beams that could be directed to detectors located thousands of kilometers away, allowing studies of neutrino oscillations with precisions not currently accessible. For example, with the neutrino source at BNL, detectors at Soudan, Minnesota (1,715 km), and Gran Sasso, Italy (6,527 km) become very interesting possibilities. The feasibility of constructing and operating such a muon-storage-ring based Neutrino-Factory, including geotechnical questions related to building non-planar storage rings (e.g. at 8degree angle for BNL-Soudan, and 3degree angle for BNL-Gran Sasso) along with the design of the muon capture, cooling, acceleration, and storage ring for such a facility is being explored by the growing Neutrino Factory and Muon Collider Collaboration (NFMCC). The authors present overview of Neutrino Factory concept based on a muon storage ring, its components, physics opportunities, possible upgrade to a full muon collider, latest simulations of front-end, and a new bowtie-muon storage ring design

Estos mapas son difíciles de validar y su precisión a nivel local puede ser muy variable. El objetivo del presente estudio fue contribuir a la validación de los mapas globales de la cubierta terrestre, comparando cinco de ellos para el caso particular del Estado de Michoacán, México. Se tomó como referencia el mapa de la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad de México y como criterios, la consistencia y el área espacial. Tomando en cuenta las leyendas iniciales, la comparación reveló incoherencias debidas en parte a las diferencias en los sistemas de clasificación. Después de establecer una leyenda unificada con seis categorías generales, la precisión global entre los mapas varió de un 9 a un 62 %.

Julga que, além de proteger a parede vascular arterial nas hipertensões arteriais súbitas, possa contribuir no mecanismo de controle e regulação do fluxo sanguíneo carotídeo, por considerar diferentes as condições fisiológicas do seio cavernoso em relação aos demais seios venosos durais e o sistema venoso endocraniano; consequente de sua constituição cavernosa, diferente dos demais canais sanguíneos venosos, com fisiollogia venosa própria e funções diferentes. Procura assemelhá-los aos demais distritos do organismo em que existem plexos cavernosos nos quais a tensão venosa chega a grandes proporções, comparada às demais regiões em que não existe esta constituição morfológica. Estabelece a correlação resultante ao mecanismo de resistência cérebro-vascular do qual considera participar, diferindo dos demais seios durais conjugado artéria carotida-beio cavernoso e veias encefálicas. Ainda valoriza o sifão carotídeo fisiologicamente e julga que o mesmo participa da hemodinâmica quando o paciente se encontra caído (em plano horizontal com hipotensão arterial, favorecendo a chegada sanguínea ao cérebro, evitando a anóxia e descerebração consequente dentro de determinados limites, sendo mais um meio de defesa do organismo.

    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.

    1996-01-01

    The RARF has a heavy-ion accelerator complex consisting of a K540-MeV ring cyclotron as a booster accelerator and two different types of injectors. The facility provides not only nuclear physicists but also researchers of atomic physics, nuclear chemistry, material science, radiobiology and others with various kinds of heavy-ion beams of an energy range of 10 MeV/nucleon to 100 MeV/nucleon. One of remarkable features of this facility is capability of supplying RI (radioactive isotope) beams with the world-highest level of intensities. In these several years the RI beam has opened up a quite new and fascinating heavy-ion science. In order to further promote this new science, we propose open-quote open-quote RIKEN RI Beam Factory close-quote close-quote as a future project of the RARF: The existing facility will be expanded into the open-quote open-quote Factory close-quote close-quote where high-intensity RI beams of the whole mass range will become available in a wide energy range up to several hundred MeV/nucleon.

    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.)

    Full Text Available El análisis de consistencia permite evaluar la seguridad en caminos en base a la velocidad. Existen diversos modelos velocidad - geometría para elementos aislados de una carretera, que se utilizan para evaluar la consistencia de elementos aislados del trazado de una carretera. Por ejemplo curvas horizontales simples o en curvas de inflexión en "S".Los modelos de análisis de consistencia agregados, permiten evaluar segmentos largos de trazado, por lo que necesitan perfiles de velocidad continuos. En este caso, los modelos y mediciones puntuales de velocidad no son adecuados. Actualmente, la tecnología de posicionamiento satelital es una manera eficiente de construir perfiles de velocidad en largas distancias del trazado, siendo particularment útil para aplicar el método de Polus. Este trabajo estudia el modelo de análisis de consistencia de Polus usando perfiles continuos de velocidad. Primero se discute dicho modelo, para luego presentar la obtención y tratamiento de datos de velocidad usando modelos y mediciones directas. El método se aplicó a 5 casos de estudio en los cual se midió en terreno la velocidad y geometría con un GPS partir del cual se obtuvieron perfiles directos y teóricos de velocidad .Los datos fueron procesados con el filtro de Kalman y suavizados con el método LOESS, para luego evaluar la consistencia de cada ruta. Se concluyó que el método de Polus y los perfiles contínuos de velocidad medidos permiten obtener una calificación de segmentos largos del trazado, pero se debe segmentar adecuadamente cada trazado para evitar sub/sobre estimaciones de consistencia.Consistency assessment permits to study road safety regarded to speed. There exist several speed-geometry models that assessed isolated components of roads, which are used for consistency assessment of single elements of roads. For instance, single horizontal curves or reverse curves. Aggregated consistency assessment models, permit to assess long

    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. We also discuss possible ways to extend our solution to permutations and graphs.

    An introductory review is given on the project of the Asymmetric Energy B factory at KEK. First, the motivation for B factory is discussed. The most interesting and important topic there is the measurement of CP violation in other than the K-system. Thus, CP violation in the B decays is reviewed rather extensively, especially on how the angles of the unitarity triangle can be measured at an asymmetric energy B factory. Then the B factory project at KEK is briefly reviewed. (author)

    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

  15. Transcriptome profiling of the theca interna in transition from small to large antral ovarian follicles.

    Directory of Open Access Journals (Sweden)

    Nicholas Hatzirodos

    Full Text Available The theca interna layer of the ovarian follicle forms during the antral stage of follicle development and lies adjacent to and directly outside the follicular basal lamina. It supplies androgens and communicates with the granulosa cells and the oocyte by extracellular signaling. To better understand developmental changes in the theca interna, we undertook transcriptome profiling of the theca interna from small (3-5 mm, n = 10 and large (9-12 mm, n = 5 healthy antral bovine follicles, representing a calculated >7-fold increase in the amount of thecal tissue. Principal Component Analysis and hierarchical classification of the signal intensity plots for the arrays showed no clustering of the theca interna samples into groups depending on follicle size or subcategories of small follicles. From the over 23,000 probe sets analysed, only 76 were differentially expressed between large and small healthy follicles. Some of the differentially expressed genes were associated with processes such as myoblast differentiation, protein ubiquitination, nitric oxide and transforming growth factor β signaling. The most significant pathway affected from our analyses was found to be Wnt signaling, which was suppressed in large follicles via down-regulation of WNT2B and up-regulation of the inhibitor FRZB. These changes in the transcriptional profile could have been due to changes in cellular function or alternatively since the theca interna is composed of a number of different cell types it could have been due to any systematic change in the volume density of any particular cell type. However, our study suggests that the transcriptional profile of the theca interna is relatively stable during antral follicle development unlike that of granulosa cells observed previously. Thus both the cellular composition and cellular behavior of the theca interna and its contribution to follicular development appear to be relatively constant throughout the follicle growth

    1990-01-01

    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).

    Full Text Available Entre los aspectos relativos a la carretera que influyen en la accidentalidad, tiene un gran peso el diseño geométrico, internacionalmente el método más empleado para la evaluación del diseño es a partir de la consistencia del trazado con modelos de perfil de velocidades de operación. Cuba no cuenta con modelos propios que consideren las características de las carreteras y los conductores, por lo que es necesario desarrollar modelos de predicción de velocidades para la evaluación de la consistencia del trazado. El desarrollo de modelos de predicción del perfil de velocidades de operación para diferentes condiciones de alineación en carreteras rurales de dos carriles en el contexto de Cuba, se efectúa a partir de características geométricas y velocidades puntuales, con análisis estadístico de las principales variables que relacionan la velocidad con el diseño. Una vez desarrollados los modelos, se aplican a un tramo de carretera declarado como tramo de concentración de accidentes (TCA de la provincia de Villa Clara localizada en la región central de Cuba, los resultados obtenidos confirman la validez de los modelos desarrollados para determinar los perfiles de velocidad de operación y de esta forma, evaluar la consistencia del trazado, con el objetivo de detectar los lugares de mayores dificultades con relación al trazado.Among the aspects that influence road accidents, geometric design is the most relevant. The most used method for evaluating the design all over the world is based on the design consistency with speed profile models of operation. Cuba does not have proprietary models that consider the characteristics of the roads and drivers, so it is necessary to develop predictive models for the evaluation of design consistency. The development of operating speed profile prediction models for different alignment conditions on rural roads with two lanes in the context of Cuba is made from the geometric characteristics and

  3. Transcriptome profiling of the theca interna from bovine ovarian follicles during atresia.

    Full Text Available The theca interna is a specialized stromal layer that envelops each growing ovarian follicle. It contains capillaries, fibroblasts, immune cells and the steroidogenic cells that synthesize androgens for conversion to estradiol by the neighboring granulosa cells. During reproductive life only a small number of follicles will grow to a sufficient size to ovulate, whereas the majority of follicles will undergo regression/atresia and phagocytosis by macrophages. To identify genes which are differentially regulated in the theca interna during follicular atresia, we undertook transcriptome profiling of the theca interna from healthy (n = 10 and antral atretic (n = 5 bovine follicles at early antral stages (<5 mm. Principal Component Analyses and hierarchical classification of the signal intensity plots for the arrays showed primary clustering into two groups, healthy and atretic. A total of 543 probe sets were differentially expressed between the atretic and healthy theca interna. Further analyses of these genes by Ingenuity Pathway Analysis and Gene Ontology Enrichment Analysis Toolkit software found most of the genes being expressed were related to cytokines, hormones and receptors as well as the cell cycle and DNA replication. Cell cycle genes which encode components of the replicating chromosome complex and mitotic spindle were down-regulated in atretic theca interna, whereas stress response and inflammation-related genes such as TP53, IKBKB and TGFB1 were up-regulated. In addition to cell cycle regulators, upstream regulators that were predicted to be inhibited included Retinoblastoma 1, E2 transcription factor 1, and hepatocyte growth factor. Our study suggests that during antral atresia of small follicles in the theca interna, arrest of cell cycle and DNA replication occurs rather than up- regulation of apoptosis-associated genes as occurs in granulosa cells.

  4. HiPER Tritium factory elements

    HiPER will include a Tritium target factory. This presentation is an overview. We start from process ideas to go to first sketch passing through safety principles. 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.

    Marine carbonate precipitation occurs in three basic modes: abiotic (or quasi-abiotic), biotically induced, and biotically controlled. On a geologic scale, these precipitation modes combine to form three carbonate production systems, or "factories" in the benthic environment: (1) tropical

  7. Prácticas y audiencias deportivas una exploración de la consistencia y dirección de sus relaciones

    Full Text Available En esta nota se comunican los resultados de una investigación en la que se han explorado las relaciones entre la adhesión a la práctica deportiva y diversos modos de adhesión a las audiencias. El interés subyacente reside en valorar empíricamente la eficacia de políticas de promoción deportiva por la vía de la popularización del deporte a través de los medios de comunicación, de la organización de grandes eventos deportivos y del proteccionismo de los modelos de práctica en que se sustentan. Los antecedentes empíricos en esta materia son escasos y nos muestran una división interna en el campo de la participación deportiva, donde tanto las prácticas como las audiencias se han configurado como subcampos independientes de investigación. Se tropieza con el problema metodológico de comparar hechos participativos de distinta naturaleza y se sugieren procedimientos particulares para la operacionalización de la participación deportiva y la clasificación de los sujetos. Los datos se obtienen de una muestra probabilística de 1.100 sujetos entre 15-60 años. Los resultados revelan que los diversos modos de las audiencias y la práctica deportiva se configuran como dimensiones independientes, sin que quepa hablar de posibles interacciones entre ellas. Asimismo, los resultados muestran una relación de carácter asimétrico que permite formular una relación de dependencia de las audiencias respecto de la práctica. Se concluye cuestionando la eficacia de promocionar el deporte por la vía de popularizar el modelo de competición.

  14. Factorials of real negative and imaginary numbers - A new perspective.

    Science.gov (United States)

    Thukral, Ashwani K

    2014-01-01

    Presently, factorials of real negative numbers and imaginary numbers, except for zero and negative integers are interpolated using the Euler's gamma function. In the present paper, the concept of factorials has been generalised as applicable to real and imaginary numbers, and multifactorials. New functions based on Euler's factorial function have been proposed for the factorials of real negative and imaginary numbers. As per the present concept, the factorials of real negative numbers, are complex numbers. The factorials of real negative integers have their imaginary part equal to zero, thus are real numbers. Similarly, the factorials of imaginary numbers are complex numbers. The moduli of the complex factorials of real negative numbers, and imaginary numbers are equal to their respective real positive number factorials. Fractional factorials and multifactorials have been defined in a new perspective. The proposed concept has also been extended to Euler's gamma function for real negative numbers and imaginary numbers, and beta function.

  15. Baby factories taint surrogacy in Nigeria.

    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.

  16. Low-energy neutrino factory design

    Directory of Open Access Journals (Sweden)

    C. Ankenbrandt

    2009-07-01

    Full Text Available 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 π^{±} decay to produce muons (μ^{±}, 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 ∼1.4×10^{21} μ^{+} per year decaying in a long straight section of the storage ring, and a similar number of μ^{-} decays.

  17. A conceptual design of circular Higgs factory

    Energy Technology Data Exchange (ETDEWEB)

    Cai, Yunhai

    2016-11-30

    Similar to a super B-factory, a circular Higgs factory (CHF) will require strong focusing systems near the interaction points and a low-emittance lattice in the arcs to achieve a factory luminosity. At electron beam energy of 125 GeV, beamstrahlung effects during the collision pose an additional challenge to the collider design. In particular, a large momentum acceptance at the 2% level is necessary to retain an adequate beam lifetime. This turns out to be the most challenging aspect in the design of a CHF. In this paper, an example will be provided to illustrate the beam dynamics in a CHF, emphasizing the chromatic optics. Basic optical modules and advanced analysis will be presented. Most importantly, we will show that 2% momentum aperture is achievable.

  18. Nuclear physics at the KAON factory

    International Nuclear Information System (INIS)

    Kitching, R.

    1989-05-01

    The author surveys the range of nuclear physics issues which can be addressed with a high intensity hadron facility such as the KAON factory. He discusses hadron spectroscopy, kaon scattering, hypernuclear physics, spin physics, and nuclear physics with neutrinos. Nuclear Physics is defined rather broadly, encompassing the study of strongly interacting systems, and including the structure of individual hadrons, hadron-hadron interactions, hadronic weak and electromagnetic currents (in nuclei too), conventional nuclear structure, and exotic nuclei. The basic theme is how the KAON Factory can shed light on non-perturbative QCD and its relation to conventional nuclear physics

  19. Particle physics prospects for the KAON factory

    1989-05-01

    The Kaon Factory at TRIUMF will produce beams of kaons, antiprotons, neutrinos and other particles with a hundred-fold increase in intensity over existing machines in the 30 GeV region. This will make possible new high precision experiments designed to test current ideas as well as high sensitivity measurements which could potentially reveal new effects. A sample of particle physics experiments involving rare kaon decays, CP and T violation studies, neutrino properties and reactions and light quark spectroscopy which might take advantage of the new opportunities presented by the Kaon Factory is discussed

    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. Volgens de auteurs van deze notitie leidt het initiatief van de Energiefabriek tot een reframing van de rol van waterschappen. Daarnaast leggen ze uit hoe het PPP-concept (People, Profit, Planet) kan fungeren als platform voor onderhandelingen tussen de actoren die betrokken zijn bij de Energiefabriek. Verder wordt met het PPP-concept aangetoond dat de Energiefabriek leidt tot ruimere maatschappelijke betrokkenheid, maatschappelijk ondernemen en winstvergroting.

    Full Text Available Descartes afirma que el cogito se “experimenta en uno” (apud se experiatur o se “siente en uno mismo” (“il sent in lui-même”, pero también ha señalado que uno no siente sino a través del cuerpo. El problema es que, en las Meditaciones, el cogito fue caracterizado cuando todavía no se había demostrado la existencia del cuerpo. Pese a esto, Descartes parece haberse dejado influir por ciertas sen- saciones internas de duda y certeza. En el trabajo se sostiene que esto fue posible porque esas sensaciones internas son efecto de una ratio implícita: la existencia de un Dios no engañador.

    Full Text Available Atualmente, a comunicação empresarial é algo imprescindível no mundo dos negócios. Em busca de crescimento e melhores resultados, as empresas sempre investiram na comunicação destinada aos clientes, o público externo. Porém, há algum tempo, percebeu-se a necessidade de conquistar o público interno, basicamente composto por empregados e familiares, para que os bons resultados e qualidade de produtos e serviços sejam mantidos. As empresas passaram a investir em ações de comunicação interna e de endomarketing para estreitar relacionamento e motivar os empregados, com o objetivo de obter os resultados esperados. Muitos profissionais costumam, erroneamente, conceituar comunicação interna e endomarketing como sinônimos. Este artigo tem por objetivo diferenciá-los.

    A 5-year-old castrated male domestic longhair cat was presented with neurological signs consistent with a central vestibular lesion and left Horner's syndrome. Computed tomography images revealed hyperattenuating, moderately contrast-enhancing material within the left tympanic bulla, most consistent with left otitis media/interna. Marked neutrophilic pleocytosis was identified on cerebrospinal fluid analysis. Streptococcus equi subspecies zooepidemicus (SEZ) was isolated from the cerebrospinal fluid. Intracranial extension of otitis media/interna is relatively infrequent in small animals. There are no reports of otitis media/interna caused by SEZ in dogs or cats. This is the first report of otitis media/interna and presumptive secondary meningoencephalitis caused by SEZ in a cat. Copyright © 2011 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

    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. Both noises and daily doses were superior than the values set by the NR-15-Annex 01 (BRASIL, 2008.

  10. Portable Material Culture and Death Factory Auschwitz

    Directory of Open Access Journals (Sweden)

    Adrian T. Myers

    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.

  11. The Physics of the B Factories

    The inspiration for this book came from Fran@cois le Diberder. During his term as spokesperson for BABAR he laid down a vision for the two B Factory detector collaborations, BABAR and Belle, to work together on a book that would describe the methodologies used and physics results obtained by those experiments. A key ideal emphasized from the outset was that this book should be written from a pedagogical perspective; it should be of interest to the student and expert alike. This vision was presented during a BABAR collaboration meeting on the island of Elba in May 2008 and a follow up Belle collaboration meeting at KEK, with visiting colleagues from the BABAR collaboration, and was embraced by the community. A number of workshops involving people from the theoretical community as well as the two collaborations were held on four continents over the following years. The resulting book, ''The Physics of the B Factories'', is a testament to the way that this concept captured the zeitgeist on both sides of the Pacific Ocean. This book is divided into three parts, the first of which provides a brief description of the B Factories, including a short (though not exhaustive) historical perspective, as well as descriptions of the detectors, ancillary data acquisition systems and data (re)processing systems that were built by the two detector collaborations in the late 1990's. The second part of the book discusses tools and methods that are frequently used when analyzing the data collected. These range from details of low level reconstruction algorithms and abstract summaries of statistical methods to high level prescriptions used when evaluating systematic uncertainties on measurements of observables. The third part of the book is devoted to physics results. This includes sufficient theoretical discussion in order for the reader to understand the context of the work being described. We are indebted to our colleagues from the theoretical community who have helped us achieve

    Feasible designs are well advanced for high-luminosity e + e - storage rings which produce B 0 bar B 0 pairs either at rest or, in what appears to be a more promising option, boosted in the detector frame. Facilities which could provide samples of 30--100 fb -1 per year on the Υ(4S) will be proposed in early 1991. Here we examine the principal physics goal of such B Factories, namely CP violation in the b system. Methods in a variety of channels, estimated event samples, and detector requirements are all considered. We conclude that the physics argument for an e + e - B Factory is well documented, and compelling. 50 refs., 22 figs., 10 tabs

    Transcription factories are nuclear domains where gene transcription takes place although the molecular basis for their formation and maintenance are unknown. In this study, we explored how the properties of chromatin as a polymer may contribute to the structure of transcription factories. We found that transcriptional active chromatin contains modifications like histone H4 acetylated at Lysine 16 (H4K16ac). Single fibre analysis showed that this modification spans the entire body of the gene. Furthermore, H4K16ac genes cluster in regions up to 500 Kb alternating active and inactive chromatin. The introduction of H4K16ac in chromatin induces stiffness in the chromatin fibre. The result of this change in flexibility is that chromatin could behave like a multi-block copolymer with repetitions of stiff-flexible (active-inactive chromatin) components. Copolymers with such structure self-organize through spontaneous phase separation into microdomains. Consistent with such model H4K16ac chromatin form foci that associates with nascent transcripts. We propose that transcription factories are the result of the spontaneous concentration of H4K16ac chromatin that are in proximity, mainly in cis

    Full Text Available Currently, from the scientific and professional practice point of view, comes out the necessity to know more about moral permissiveness, as it seems to be an increase in “moral relativism”.. Because it, it this is important to have tools to collect valid and reliable information about moral in social situations defined as social and personal behavior issue. This paper presents a technical note of The Morally Debatable Behaviors Scale (MDBS from Harding & Phillips (1986, which was developed in USA and mainly focused on young people and adults. This technical note makes direct reference to a recent Latin American study (Merino & Grimaldo, 2010; this article focuses on the internal structure and the problems associated with evidences of factorial complexity among items of the MDBS. This means that the interpretation of scores is not factorially simple and could not be achieved by a conceptual distinction between the latent constructs applied to the study sample.. The results in the previous study of the factorial complexity leads the researcher to decide whether an instrument for measuring this aspect may contain a reasonable amount of complexity that is consistent with what is in reality, or look for the unidimensional and simple structure.

  2. Backgrounds at e+e- B factories

    International Nuclear Information System (INIS)

    Ehrlich, R.D.

    1994-01-01

    B-factory designers and prospective users have learned that the viability of such facilities is crucially dependent upon control of machine-related backgrounds in the interaction region (IR). Photons from synchrotron radiation (SR), and the debris that follows loss of stored beam, can compromise the performance and thwart the mission of the elaborate and expensive experimental detectors. This danger is relevant to taucharm and phi factories as well. My goal is to make clear to non-experts why this is so, and to explicate the underlying physical processes and important defensive measures. We shall stay close to reality by comparing simulation to actual experience at the CLEOII detector - CESR storage ring complex at Cornell. Why should one expect background difficulties at B factories? First, backgrounds are not negligible now, at luminosities of 2.10 32 cm 2 sec -1 ; future facilities will require currents and luminosity 10 to 50 times greater. Second, backgrounds rise faster than linearly with beam current; since gas evolution is driven by SR, the beam-gas backgrounds will grow quadratically with current. High beam energies (for asymmetric colliders) and the very strong quadrupole fields required for small β * and rapid beam separation exacerbate the problems posed by SR from magnets near the IR. The experiments will employ thin beryllium beampipes at (typically) 2.5 cm radius, with little inherent resistance to penetration by x rays. Finally, the HEP physics is ''high-precision physics,'' especially vulnerable to corruption by backgrounds. (orig.)

    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 + e - collider capable of achieving a luminosity of L = 3 x 10 33 cm -2 s -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

    Metabolic engineering and synthetic biology offer great prospects in developing microbial cell factories capable of converting renewable feedstocks into fuels, chemicals, food ingredients, and pharmaceuticals. However, prohibitively low production rate and mass concentration remain the major hurdles in industrial processes even though the biosynthetic pathways are comprehensively optimized. These limitations are caused by a variety of factors unamenable for host cell survival, such as harsh industrial conditions, fermentation inhibitors from biomass hydrolysates, and toxic compounds including metabolic intermediates and valuable target products. Therefore, engineered microbes with robust phenotypes is essential for achieving higher yield and productivity. In this review, the recent advances in engineering robustness and tolerance of cell factories is described to cope with these issues and briefly introduce novel strategies with great potential to enhance the robustness of cell factories, including metabolic pathway balancing, transporter engineering, and adaptive laboratory evolution. This review also highlights the integration of advanced systems and synthetic biology principles toward engineering the harmony of overall cell function, more than the specific pathways or enzymes. © 2017 WILEY-VCH Verlag GmbH & Co.

  5. Neutrinos: from the Workshop to the Factory

    CERN Multimedia

    2001-01-01

    Over the next 5 years much work will be done to reach a theoretical and practical description of a neutrino factory. How could this project turn out to be an interesting future option for CERN? Neutrino beams travelling from CERN to the Canary Islands? And to the Svalbard archipelago in Norway? Or even to the Pyhaesalmi Mine in Finland? Why neutrinos? And why so far? The answers provide one of CERN's next challenging options: the construction of a high-energy muon storage ring to provide neutrino beams. This project, nicknamed 'neutrino factory', now figures in CERN's middle term plan as a recognized and supported research and development project. International collaborations, with other European laboratories and also with America and Japan, are now being set up. Long baseline locations for neutrino oscillations studies at a CERN based neutrino factory. Early in its history, LEP established that there exist just three kinds of light neutrinos, those associated with the electron, muon, and tau leptons. For a...

  6. Ultrastructural Characterization of Zika Virus Replication Factories

    Full Text Available Summary: A global concern has emerged with the pandemic spread of Zika virus (ZIKV infections that can cause severe neurological symptoms in adults and newborns. ZIKV is a positive-strand RNA virus replicating in virus-induced membranous replication factories (RFs. Here we used various imaging techniques to investigate the ultrastructural details of ZIKV RFs and their relationship with host cell organelles. Analyses of human hepatic cells and neural progenitor cells infected with ZIKV revealed endoplasmic reticulum (ER membrane invaginations containing pore-like openings toward the cytosol, reminiscent to RFs in Dengue virus-infected cells. Both the MR766 African strain and the H/PF/2013 Asian strain, the latter linked to neurological diseases, induce RFs of similar architecture. Importantly, ZIKV infection causes a drastic reorganization of microtubules and intermediate filaments forming cage-like structures surrounding the viral RF. Consistently, ZIKV replication is suppressed by cytoskeleton-targeting drugs. Thus, ZIKV RFs are tightly linked to rearrangements of the host cell cytoskeleton. : Cortese et al. show that ZIKV infection in both human hepatoma and neuronal progenitor cells induces drastic structural modification of the cellular architecture. Microtubules and intermediate filaments surround the viral replication factory composed of vesicles corresponding to ER membrane invagination toward the ER lumen. Importantly, alteration of microtubule flexibility impairs ZIKV replication. Keywords: Zika virus, flavivirus, human neural progenitor cells, replication factories, replication organelles, microtubules, intermediate filaments, electron microscopy, electron tomography, live-cell imaging

    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.

    Full Text Available The present research assessed the reliability, factorial validity and measurement invariance (by gender of the Portuguese version of TEOSQ –Task and Ego Orientation in Sport Questionnaire (Fonseca & Biddle, 2001. Data were collected from 1010 physical education students with a mean age of 15.42 ( SD=1.91. Factorial and invariance measurements were tested via confirmatory factorial analysis. Results supported internal consistency for the two proposed subscales (task and ego. Based on modification indices and theoretical justification the TEOSQ p was reduced to 12 items with better goodness-of-fit indices for the oblique model. The results of gender invariance did not provide full empirical support to the multi-group equivalence assumption, being suggested that TEOSQ p does not measure in the same way goal orientations for boys (orthogonal model and girls (oblique model. In light of these results, conceptual, empirical and practical issues were discussed.

  19. Diamond Growth in the Subduction Factory

    Bureau, H.; Frost, D. J.; Bolfan-Casanova, N.; Leroy, C.; Estève, I.

    2014-12-01

    Natural diamonds are fabulous probes of the deep Earth Interior. They are the evidence of the deep storage of volatile elements, carbon at first, but also hydrogen and chlorine trapped as hydrous fluids in inclusions. The study of diamond growth processes in the lithosphere and mantle helps for our understanding of volatile elements cycling between deep reservoirs. We know now that inclusion-bearing diamonds similar to diamonds found in nature (i.e. polycrystalline, fibrous and coated diamonds) can grow in hydrous fluids or melts (Bureau et al., GCA 77, 202-214, 2012). Therefore, we propose that the best environment to promote such diamonds is the subduction factory, where highly hydrous fluids or melts are present. When oceanic plates are subducted in the lithosphere, they carry an oceanic crust soaked with seawater. While the slabs are traveling en route to the mantle, dehydration processes generate saline fluids highly concentrated in NaCl. In the present study we have experimentally shown that diamonds can grow from the saline fluids (up to 30 g/l NaCl in water) generated in subducted slabs. We have performed multi-anvil press experiments at 6-7 GPa and from 1300 to 1400°C during 6:00 hours to 30:00 hours. We observed large areas of new diamond grown in epitaxy on pure diamond seeds in salty hydrous carbonated melts, forming coated gems. The new rims are containing multi-component primary inclusions. Detailed characterizations of the diamonds and their inclusions have been performed and will be presented. These experimental results suggest that multi-component salty fluids of supercritical nature migrate with the slabs, down to the deep mantle. Such fluids may insure the first stage of the deep Earth's volatiles cycling (C, H, halogen elements) en route to the transition zone and the lower mantle. We suggest that the subduction factory may also be a diamond factory.

    Separated-function racetrack lattices have been developed for the KAON Factory accelerators that have more flexibility than the old circular lattices. The arcs of the large rings have a regular FODO structure with a superimposed six-fold symmetric modulation of the betafunction in order to raise γ t to infinity. In the small rings, γ t is kept high enough by choosing a sufficiently large phase advance in the arcs. Straight sections with zero dispersion are provided for rf cavities and fast injection and extraction, and with controlled dispersion for H - injection and slow extraction. The ion-optical properties of the lattices and the results from tracking studies are discussed

  9. Rare B decays at B factories

    Radiative and Electroweak Penguin Decays are Flavor Changing Neutral Currents (FCNC) occurring in the Standard Model only at the loop level. They are characterized by high sensitivity to New Physics (they can appear in the loop with size comparable to leading SM contributions) and they are Complementary to the direct production of new particles expected at LHC. Huge datasets collected at the two B- factories, BaBar and Belle, have made it possible to explore precisely these decays in exclusive channels and inclusive measurements. b →sγ, b→dγ, b→s l + l - , B + →τν, B→Dτν etc measured provide tests of SM predictions and interesting BSM constraints: Charged Higgs bounds from b →sγ, B + →τν, B + →Dτν; Constraints on Wilson coefficients C 7 , C 9 and C 10 ; and Constraints on |V td |/|V ts |. They provide interesting signatures: B(B + →τ + ν) direct measurement versus CKM fit; and large forward-backward asymmetry of K* l + l - . Final Belle/BaBar data samples are yet to be analyzed and even more interesting results are expected at Super B factories with two orders of magnitude larger data samples

  10. Muon Acceleration: Neutrino Factory and Beyond

    Energy Technology Data Exchange (ETDEWEB)

    Bogacz, Alex [Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)

    2018-03-01

    We summarize the current state of a concept for muon acceleration aimed at a future Neutrino Factory and extendable to Higgs Factory. The main thrust of these studies was to reduce the overall cost while maintaining performance by exploring the interplay between the complexity of the cooling systems and the acceptance of the accelerator complex. To ensure adequate survival for 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 an initially low RF frequency, e.g., 325 MHz, which is 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. We consider an SRF-efficient design based on a multi-pass (4.5) ?dogbone? RLA, extendable to multi-pass FFAG-like arcs.

    Full Text Available Este trabajo tiene como propósito reflexionar sobre algunas circunstancias que, en Argentina, contribuyen a la crisis de la educación médica y al descontento tanto de pacientes como de profesionales. El centro de atención es la medicina interna. Del análisis surgen algunas paradojas vinculadas con la actual formación de grado y posgrado. Si bien el primer nivel de atención de la salud, en el marco de la atención primaria, puede resolver el 80% de los problemas de salud de la población, la enseñanza de la medicina interna continúa realizándose sobre el paciente hospitalizado. Esto afecta a la forma en que se practica la medicina, pues se privilegia la tecnología en el diagnóstico y tratamiento sobre la prevención de las enfermedades y la promoción de la salud. Las causas de este panorama son varias, destacando el poco tiempo dedicado a la educación en el ámbito del consultorio con pacientes ambulatorios.

    Full Text Available Palm oil that was discarded as waste from chip factories after the frying of potatoes was used for the production of toilet soap. The discarded oil was purified with a brine solution and bleached with H2O2 . Purified bleached discarded palm oil (P.B.D.P.O. was mixed with two materials commonly used in toilet soap manufacturing, i.e., inedible tallow (I.T. and palm kernel oil (P.K.O. at different ratios for the preparation of toilet soap. The data revealed that using P.B.D.P.O. up to 30 % as a substitute for I.T. produced fine toilet soaps from the view point of; hard consistency, soft surface, good hand lather preference and medium erosion from hand washing. The soap samples containing more than 30 % P.B.D.P.O. as a substitute for I. T. gave bad quality. After the storage of soap samples for 6 months at room temperature, significant improvements in the physical properties of the soap samples at different ratios were found. It could be recommended that discarded palm oil from chip frying factories can be used after purification and bleaching in place of inedible tallow up to 30 % to produce a fine toilet soap.El aceite de palma que se desecha de las fábricas de patatas chips se utilizó para producir jabón de tocador. Dicho aceite se purificó mediante lavado con una salmuera y blanqueado con H2O2 .

  19. AutoPyFactory and the Cloud

    CERN Document Server

    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...

    1990-06-01

    The study of rare and CP-violating B meson decays is well suited to a high-luminosity e + e - collider. For studying certain decay processes there are also substantial benefits associated with asymmetric beam energies, which give a moving center of mass for the B mesons. We describe a design for a 9 GeV x 3.1 GeV B Factory in the PEP tunnel that would operate initially at a luminosity of 3 x 10 33 cm -2 s -1 . Technical problems include issues related to high currents (e.g., beam instabilities, feedback systems, lifetime degradation and detector radiation power dissipation) and those related to the hetero-energetic beams (e.g., beam separation, beam-beam interaction and detector requirements). Issues requiring R ampersand D effort are identified. 8 refs., 2 figs., 2 tabs

Si bien la investigación psicológica ha demostrado en numerosas ocasiones la relación existente entre comprensión y producción en el sentido de una maduración anterior de la primera con respecto a la segunda, podemos considerar a priori la existencia de indicadores que nos permitan medir ambos aspectos. Para ello buscamos la estructura factorial que presentan los indicadores lingüísticos que vamos a considerar y comprobaremos si presenta los factores encontrados en comprensión lectora.

  4. The EC's next global warming factories

    International Nuclear Information System (INIS)

    Kerr, A.

    1993-12-01

    Greenpeace suggests that, because they waste far more of the fuel's energy than they transform into electricity, fossil fuel power plants would more accurately be called global warming factories. Electricity is effectively only a by-product. Although the European Community's Energy and Environment ministers three years ago agreed to stabilise rising CO 2 emissions, the strategy proposed by the European Commission would have virtually no impact on the electricity sector, the largest source of CO 2 . Emissions threaten to be 17% higher in 2000 than in 1990 yet power companies are building more plants. Greenpeace has compiled a list of the next 145 global warming factories in the EC amounting to 90,000 MW with the potential to emit around 375 million tonnes CO 2 per year. More strenuous efforts must be made to curb CO 2 emissions. A UN panel of the world's leading climate scientists has confirmed its earlier findings justifying deep cuts in CO 2 emissions. Part of the solution lies in severing the link between electricity sales and power companies' profits. Even the best efforts to save energy will be undermined by the power sector unless its profitability is coupled to improving customer energy efficiency. A planning framework along these lines known as Integrated Resource Planning (IRP) has performed successfully in North America for over a decade. Greenpeace is calling for a moratorium on power plant construction until options for saving energy are exhausted and a shake-up of the power sector in Europe to put energy efficiency first with the rapid introduction of new power planning legislation at national and Community levels concerning IRP. 2 refs., 3 tabs

  5. Evolution of the Factory 1975-2006

    International Nuclear Information System (INIS)

    2006-01-01

    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

    Full Text Available A passagem da modernidade para a pós-modernidade vem sendo intensamente estudada de uma perspectiva macro, ou social. São, no entanto, poucos os estudos que procuram compreender como está dando-se essa transição do ponto de vista micro, ou individual. Esse é o objetivo do presente trabalho. Uma análise do discurso de jovens entre 18 e 25 anos sobre o seu uso de telefones celulares deu visibilidade parcial a essa transição interna e permitiu identificar um processo de interpenetração de campos semânticos que dá concretude psicológica a algumas das principais características do mundo contemporâneo: seu imediatismo e sua fluidez.

    The purpose of this study was to investigate the ultrastructure of the membrana limitans interna (internal limiting membrane, ILM) and to evaluate alterations to the retinal cell layers after membrane peeling with vital dyes. Twenty-five patients (25 eyes) who underwent macular hole surgery were included, whereby 12 indocyanine green (ICG)- and 13 brilliant blue G (BBG)-stained ILM were analyzed using light, transmission electron and scanning electron microscopy. Retinal cell fragments on the ILM were identified in both groups using immunohistochemistry. Comparing ICG- and BBG-stained membranes, larger cellular fragments were observed at a higher frequency in the BBG group. Thereby, the findings indicate that ICG permits an enhanced separation of the ILM from the underlying retina with less mechanical destruction. A possible explanation might be seen in the known photosensitivity of ICG, which induces a stiffening and shrinkage of the ILM but also generates retinal toxic metabolites. Copyright © 2011 S.

    2014-10-01

    Full Text Available En la teoría jurídica actual el ámbito constitucional es la plataforma para la garantía de los derechos y las libertades; sin embargo, la Constitución mexicana prevé supuestos que son excluyentes entre sí. Esta circunstancia implica prescribir en el nivel constitucional un derecho y, a su vez, un no derecho, lo que por consecuencia crea un sincretismo metodológico. Este texto, además de denunciar tal contradicción, defiende la premisa de que la Constitución requiere de coherencia interna. Dicha idea toma como base el principio de igualdad y la interpretación judicial, para adecuar la coherencia teórica y normativa de la carta constitucional.

Mediante este artículo se pretende hacer una reflexión sobre las migraciones internas e internacionales, en lo cual hacemos hincapié la entrada de extranjeros sea en forma regular e principalmente irregular cada vez más pronunciada en Mozambique. El procedimiento de recolección y procesamiento de datos fueron basados principalmente en la investigación bibliográfica, revisión de documentos y el análisis de los datos estadísticos disponibles sobre la migración en Mozambique. Los resultados de la investigación sugieren que la migración y la movilidad en Mozambique varían según la ubicación, perfil histórico, económico y ambiental de las regiones. Continúa la tendencia de la migración a los países vecinos, especialmente a Sudáfrica, al mismo tiempo que se observa la entrada de inmigrantes de diversas partes del mundo, provenientes en su mayoría de países africanos, que atraídos por la relativa estabilidad socioeconómica y política del país, buscan seguridad y mejores condiciones de vida.

    1994-01-01

    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.

    Full Text Available With the advent of modern biotechnology, microorganisms from diverse lineages have been used to produce bio-based feedstocks and bioactive compounds. Many of these compounds are currently commodities of interest, in a variety of markets and their utility warrants investigation into improving their production through strain development. In this review, we address the issue of strain improvement in a group of organisms with strong potential to be productive “cell factories”: the photosynthetic microalgae. Microalgae are a diverse group of phytoplankton, involving polyphyletic lineage such as green algae and diatoms that are commonly used in the industry. The photosynthetic microalgae have been under intense investigation recently for their ability to produce commercial compounds using only light, CO2, and basic nutrients. However, their strain improvement is still a relatively recent area of work that is under development. Importantly, it is only through appropriate engineering methods that we may see the full biotechnological potential of microalgae come to fruition. Thus, in this review, we address past and present endeavors towards the aim of creating productive algal cell factories and describe possible advantageous future directions for the field.

    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...

  11. Hospitals as factories of medical garbage.

    2017-12-01

    Over the course of the twentieth century, as hospitals cleaned up, they came to produce more and more rubbish. Beginning in the 1970s and gaining pace in the 1980s and 1990s, single-use plastic items (syringes, blood bags, tubing) saturated everyday medical practice across the globe. This essay brings the question of plastic to bear upon the longer history of twentieth century sanitary science. The widespread adoption of single-use disposable medical plastics consolidated a century's worth of changes in medical hygiene. As strange as it may seem today, the initial uptake of medical plastics was not driven primarily by concerns about hygiene. Plastic began as a mid-century technology of convenience and durability. It was not until the end of the twentieth century that it morphed into a powerful symbol and instrument of medical hygiene. Today, both patients and practitioners have embraced plastic as an indispensable technology of clean medicine. The procession of single-use medical plastics through everyday medicine now comprises a constant, if disposable, infrastructure of medical hygiene. This new processional infrastructure of disposable hygiene has produced another, albeit unintended, consequence. This new regime has exponentially increased hospitals' material outputs. In so doing, plastic has refigured the ecologies of everyday medicine. Plastic hygiene has rendered hospitals factories of medical garbage.

  12. The factorial structure of pathological gambling.

    Pathological gambling has been characterised by DSM-III-R and DSM-IV as a disorder of impulse control with a proportion of gamblers identified as meeting criteria for a co-morbid diagnosis of Antisocial Personality Disorder. To date, empirical evidence in support of the notion that pathological gamblers as a group manifest elevated traits of impulsivity remains equivocal. Principal components analysis was used to investigate relationships between the constructs of impulsivity, psychopathy, DSM-III-R criteria for Antisocial Personality Disorder, psychological distress, criminal offending behavior and a range of other common psychological measures employed with pathological gamblers. The sample comprised 115 pathological gamblers, 80 consecutive gamblers seeking treatment from a general hospital psychiatric inpatient behavior therapy unit, and 35 volunteer Gamblers Anonymous attenders. Four primary factors were determined: psychological distress, sensation seeking, crime and liveliness, and impulsive-antisocial. Results suggest that pathological gambling consists of a number of discrete and reproducible factorial structures. The impulsive antisocial factor was found to be associated with gambling behavior and indices of poor psychosocial functioning.

    A global concern has emerged with the pandemic spread of Zika virus (ZIKV) infections that can cause severe neurological symptoms in adults and newborns. ZIKV is a positive-strand RNA virus replicating in virus-induced membranous replication factories (RFs). Here we used various imaging techniques to investigate the ultrastructural details of ZIKV RFs and their relationship with host cell organelles. Analyses of human hepatic cells and neural progenitor cells infected with ZIKV revealed endoplasmic reticulum (ER) membrane invaginations containing pore-like openings toward the cytosol, reminiscent to RFs in Dengue virus-infected cells. Both the MR766 African strain and the H/PF/2013 Asian strain, the latter linked to neurological diseases, induce RFs of similar architecture. Importantly, ZIKV infection causes a drastic reorganization of microtubules and intermediate filaments forming cage-like structures surrounding the viral RF. Consistently, ZIKV replication is suppressed by cytoskeleton-targeting drugs. Thus, ZIKV RFs are tightly linked to rearrangements of the host cell cytoskeleton. Copyright © 2017 The Author(s).

  14. 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...

  15. Multilevel Factorial Designs With Experiment-Induced Clustering.

    2017-04-06

    Factorial experimental designs have many applications in the behavioral sciences. In the context of intervention development, factorial experiments play a critical role in building and optimizing high-quality, multicomponent behavioral interventions. One challenge in implementing factorial experiments in the behavioral sciences is that individuals are often clustered in social or administrative units and may be more similar to each other than to individuals in other clusters. This means that data are dependent within clusters. Power planning resources are available for factorial experiments in which the multilevel structure of the data is due to individuals' membership in groups that existed before experimentation. However, in many cases clusters are generated in the course of the study itself. Such experiment-induced clustering (EIC) requires different data analysis models and power planning resources from those available for multilevel experimental designs in which clusters exist prior to experimentation. Despite the common occurrence of both experimental designs with EIC and factorial designs, a bridge has yet to be built between EIC and factorial designs. Therefore, resources are limited or nonexistent for planning factorial experiments that involve EIC. This article seeks to bridge this gap by extending prior models for EIC, developed for single-factor experiments, to factorial experiments involving various types of EIC. We also offer power formulas to help investigators decide whether a particular experimental design involving EIC is feasible. We demonstrate that factorial experiments can be powerful and feasible even with EIC. We discuss design considerations and directions for future research.

  16. Survivor shielding. Part A. Nagasaki factory worker shielding

    Recent investigations based on conventional chromosome aberration data by the RERF suggest that the DS86 doses received by many Nagasaki factory workers may have been overestimated by as much as 40% relative to those for other survivors in Japanese-type houses and other shielding configurations (Kodama et al. 2001). Since the factory workers represent about 25% of the Nagasaki survivors with DS86 doses in excess of 0.5 Gy (50 rad), systematic errors in their dose estimates can have a major impact on the risk coefficients from RERF studies. The factory worker doses may have been overestimated for a number of reasons. The calculation techniques, including the factory building modeling, weapon source spectra and cross-section data used in the DS86 shielding calculations were not detailed enough to replicate actual conditions. The models used did not take into account local shielding provided by machinery, tools, and the internal structure in the buildings. In addition, changes in the disposition of shielding following collapse of the building by the blast wave were not considered. The location of large factory complexes may be uncertain, causing large numbers of factory survivors, correctly located relative to each other, to be uniformly too close to the hypocenter. Any or all of these reasons are sufficient to result in an overestimate of the factory worker doses. During the DS02 studies, factory worker doses have been reassessed by more carefully modeling the factory buildings, incorporating improved radiation transport methods and cross-section data and using the most recent bomb leakage spectra (Chapter 2). Two-dimensional discrete ordinates calculations were carried out initially to estimate the effects of workbenches and tools on worker doses to determine if the inclusion of these components would, in fact, reduce the dose by amounts consistent with the RERF observations (Kodama et al. 2001).

    Full Text Available A injúria interna de impacto causa redução significativa da qualidade de frutos de tomate. O presente trabalho teve como objetivo avaliar a utilização do armazenamento sob atmosfera controlada na redução do desenvolvimento de uma desordem de amadurecimento conhecida como injúria interna de impacto. Tomates (Lycopersicon esculentum Mill, cv. Solimar, foram colhidos no estádio de amadurecimento verde-maduro e tratados com etileno, por 12 horas, a 20degreesC. Ao atingirem o estádio verde-rosado, sofreram uma queda de 40 cm de altura sobre uma superfície plana, lisa e maciça. Metade dos frutos foi então armazenada sobre atmosfera controlada (3% O2; 4% CO2; balanço com N2 por 8 dias a 20degreesC e 85-95% de umidade relativa, e então foram transferidos para atmosfera ambiente até completamente maduros. A outra metade dos frutos foi mantida continuamente em atmosfera ambiente à mesma temperatura e umidade relativa. Quando estavam completamente maduros, os frutos que sofreram injúria mecânica, armazenados sob atmosfera controlada e sob atmosfera ambiente, desenvolveram sintomas de injúria interna de impacto no tecido locular. O armazenamento sob atmosfera controlada não produziu efeitos significativos no conteúdo de vitamina C total e carotenóides totais para o pericarpo e o tecido locular injuriados. Entretanto, o tecido locular injuriado do tratamento armazenado sob atmosfera controlada possuía acidez titulável 15% superior (ao redor de 162 meq ácido cítrico. kg-1 do que o tratamento sob atmosfera ambiente (ao redor de 140 meq ácido cítrico. kg-1 e era similar ao tratamento não injuriado, armazenado em atmosfera ambiente (ao redor de 174 meq ácido cítrico. kg-1.

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

    It is widely accepted that some performance function has been optimized during the evolution of metabolic pathways. One can study the nature of such a function by analogy with the industrial manufacturing world, in which there have been efforts over recent decades to optimize production chains, and in which it is now accepted that fluxes are not the only important system variables that determine process efficiency, because inventory turnover must also be considered. Inspired by the parallels between living cells and manufacturing factories, we propose that fluxes and transit time may have simultaneously been major targets of natural selection in the optimization of the design, structure and kinetic parameters of metabolic pathways. Accordingly we define the ratio of flux to transit time as a performance index of productivity in metabolic systems: it measures the efficiency with which stocks are administered, and facilitates comparison of a pathway in different steady states or in different tissues or organisms. For a linear chain of two enzymes, at a fixed total equilibrium constant, we have analysed the variation of flux, transit time and productivity index as functions of the equilibrium constants of the two steps. The results show that only the productivity index has a maximum, which represents a good compromise in optimizing flux and transit time. We have extended control analysis to the productivity index and derived the summation theorem that applies to it. For linear chains of different length with maximum productivity index values, the distribution of control coefficients with regard to the three parameters has a characteristic profile independent of the length of the chain. Finally, this control profile changes when other variables are optimized, and we compare the theoretical results with the control profile of the first steps of glycolysis in rat liver.

  1. PEP-II: An asymmetric B factory

    International Nuclear Information System (INIS)

    1993-06-01

    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 10 33 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. Utilities already installed in the PEP tunnel are largely sufficient to operate the two PEP-II storage rings

  2. Make your company a talent factory.

    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).

  11. Responsabilidad social interna: entre la diferencia y el discurso en el escenario organizaciona

    Directory of Open Access Journals (Sweden)

    Nancy Piedad Diaz Ortiz

    Full Text Available El ensayo plantea que el discurso de la Responsabilidad Social Interna, como modelo de gestión, pretende homogenizar el tratamiento de los actores internos de la organización, una vez que es utilizado desde una perspectiva instrumental enfocada exclusivamente en temas legales de la relación laboral, en contraposición a una perspectiva sustantiva centrada en la humanización del ambiente laboral. En consecuencia, bajo este discurso, las organizaciones esconden prácticas que son, en verdad, des-humanizantes en la convivencia social y fomentan aún más la intolerancia hacia la diferencia. La discusión se contextualiza en Latinoamérica, en que cobran fuerza los discursos de la interculturalidad y de la defensa de los derechos humanos en las agendas políticas y empresariales, lo que resalta las contradicciones inherentes a estos discursos. A partir de una revisión bibliográfica sobre responsabilidad social, discurso, teoría de la identidad social y del autoconcepto, se discutieron los mecanismos individuales, sociales y organizacionales de elaboración y superación de estereotipos, que ayudan al individuo a establecer referencias para las percepciones e interpretación de la realidad. Se cuestiona que el discurso de la responsabilidad social interna podría proponer un cambio en la forma como se tratan los individuos en la organización. En este contexto, la diferencia no existiría como forma de exclusión social, más bien sería un medio para promover la equidad, valorando las particularidades de la acción individual en la organización, y no en el sentido de reforzar la diferencia entre el "nosotros" y "ellos" en función del rol que se ejerce en la dinámica organizacional.

  15. Oscillations of factorial cumulants to factorial moments ratio from an eikonal approach

    Beggio, P.C., E-mail: beggio@uenf.br [Universidade Federal do Rio Grande do Sul – UFRGS, Porto Alegre, RS (Brazil); Universidade Estadual do Norte Fluminense Darcy Ribeiro – UENF, Campos dos Goytacazes, RJ (Brazil)

    2013-09-02

    We study the factorial moments (F{sub q}), the factorial cumulants (K{sub q}) and the ratio of K{sub q} to F{sub q} (H{sub q}=K{sub q}/F{sub q}) in pp/pp{sup ¯} 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 F{sub q} moments, correctly predicts that the first minimum of the H{sub q} lies around q=5 and qualitatively reproduces the oscillations of the H{sub q} moments, as shown in the experimental data and predicted by QCD at preasymptotic energy. The result of this study seems to indicate that the H{sub q} oscillations are manifestations of semihard component in the multiparticle production process. Predictions for multiplicity distribution and H{sub q} moments at the LHC energy of √(s)=14 TeV are presented.

    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.

    Noncommunicable diseases (NCDs) are becoming more prevalent in India. The data for presence of NCDs and its risk factors among factory workers is deficient in India. A cross-sectional comparative study was carried out among 37 factory workers and equal number of comparable subjects from general population. Screening for presence of diabetes along with its risk factors was made in both the groups using pretested predesigned World Health Organization STEPwise approach to surveillance (WHO STEPS) questionnaire in rural area of Delhi. Data was analyzed using SPSS version 16 software. The estimation of risk in two groups was done with calculation of odds ratio (OR). P values less than 0.05 were considered significant. A total of 74 participants were included in the present study. Hypertension and diabetes was present in 13.5 and 5.4% of factory workers and four (10.8%) and three (8.8%) subjects in comparative group, respectively. Seven (18.9%) factory and eight (21.6%) non-factory subjects fell in the category of current smoker or smokeless tobacco users. High density lipoprotein levels were found abnormal among one (2.7%) factory worker and nine (24.3%) subjects in comparative group (P-value = 0.01). Behavioral risk factors, alcohol consumption, and fruits and vegetable intake were significantly different among two groups. Factory workers were having better profile than non-factory subjects except for risk factors such as alcohol intake and inadequate fruits and vegetable intake. However, healthy worker effect phenomenon cannot be ruled out.

  14. 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

    Factorial experiments have rarely been used in the development or evaluation of clinical interventions. However, factorial designs offer advantages over randomized controlled trial designs, the latter being much more frequently used in such research. Factorial designs are highly efficient (permitting evaluation of multiple intervention components with good statistical power) and present the opportunity to detect interactions amongst intervention components. Such advantages have led methodologists to advocate for the greater use of factorial designs in research on clinical interventions (Collins, Dziak, & Li, 2009). However, researchers considering the use of such designs in clinical research face a series of choices that have consequential implications for the interpretability and value of the experimental results. These choices include: whether to use a factorial design, selection of the number and type of factors to include, how to address the compatibility of the different factors included, whether and how to avoid confounds between the type and number of interventions a participant receives, and how to interpret interactions. The use of factorial designs in clinical intervention research poses choices that differ from those typically considered in randomized clinical trial designs. However, the great information yield of the former encourages clinical researchers' increased and careful execution of such designs. Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available Bangladesh is a developing country and has a lot of factories for different products for local use and also export to abroad. Garments industries are one of the top most items of exported items. A huge number of populations are working in garments industries. But these factories are not well designed in sense of the thermal environment. Workers experiences sickness related to indoor environment. The productions of these factories are affected due to employees’ health condition. The research is done in two different methods. One is empirical data collection using thermal data loggers and the other is questionnaire survey on the spots for three factory buildings. The field study was conducted in four different months of the same year during winter and summer period. Expected findings of this research are that the indoor environment is not comfortable for works at day time during summer season. This research will help the factory workers in providing a comfortable thermal environment and also help the employers or factory owners to increase their production margin.

    Full Text Available In studies using isolated ovarian granulosa and thecal cells it is important to assess the degree of cross contamination. Marker genes commonly used for granulosa cells include FSHR, CYP19A1 and AMH while CYP17A1 and INSL3 are used for thecal cells. To increase the number of marker genes available we compared expression microarray data from isolated theca interna with that from granulosa cells of bovine small (n = 10 for both theca and granulosa cells; 3-5 mm and large (n = 4 for both theca and granulosa cells, > 9 mm antral follicles. Validation was conducted by qRT-PCR analyses. Known markers such as CYP19A1, FSHR and NR5A2 and another 11 genes (LOC404103, MGARP, GLDC, CHST8, CSN2, GPX3, SLC35G1, CA8, CLGN, FAM78A, SLC16A3 were common to the lists of the 50 most up regulated genes in granulosa cells from both follicle sizes. The expression in theca interna was more consistent than in granulosa cells between the two follicle sizes. Many genes up regulated in theca interna were common to both sizes of follicles (MGP, DCN, ASPN, ALDH1A1, COL1A2, FN1, COL3A1, OGN, APOD, COL5A2, IGF2, NID1, LHFP, ACTA2, DUSP12, ACTG2, SPARCL1, FILIP1L, EGFLAM, ADAMDEC1, HPGD, COL12A1, FBLN5, RAMP2, COL15A1, PLK2, COL6A3, LOXL1, RARRES1, FLI1, LAMA2. Many of these were stromal extracellular matrix genes. MGARP, GLDC, CHST8, GPX3 were identified as new potential markers for granulosa cells, while FBLN5, OGN, RAMP2 were significantly elevated in the theca interna.

    Spatial analysis is considered as one of the most important science for identifying the most appropriate site for industrialization and also to alleviate the environmental ramifications caused by factories. This study aims at analyzing the Assalaya sugarcane factory site by the use of spatial analysis to determine whether it has ramification on the White Nile River. The methodology employed for this study is Global Position System (GPS) to identify the coordinate system of the study phenomena and other relative factors. The study will also make use Geographical Information System (GIS) to implement the spatial analysis. Satellite data (LandsatDem-Digital Elevation Model) will be considered for the study area and factory in identifying the consequences by analyzing the location of the factory through several features such as hydrological, contour line and geological analysis. Data analysis reveals that the factory site is inappropriate and according to observation on the ground it has consequences on the White Nile River. Based on the finding, the study recommended some suggestions to avoid the aftermath of any factory in general. We have to take advantage of this new technological method to aid in selecting most apt locations for industries that will create an ambient environment.

    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.

    Full Text Available Abstract Background The evaluation of more than one intervention in the same randomised controlled trial can be achieved using a parallel group design. However this requires increased sample size and can be inefficient, especially if there is also interest in considering combinations of the interventions. An alternative may be a factorial trial, where for two interventions participants are allocated to receive neither intervention, one or the other, or both. Factorial trials require special considerations, however, particularly at the design and analysis stages. Discussion Using a 2 × 2 factorial trial as an example, we present a number of issues that should be considered when planning a factorial trial. The main design issue is that of sample size. Factorial trials are most often powered to detect the main effects of interventions, since adequate power to detect plausible interactions requires greatly increased sample sizes. The main analytical issues relate to the investigation of main effects and the interaction between the interventions in appropriate regression models. Presentation of results should reflect the analytical strategy with an emphasis on the principal research questions. We also give an example of how baseline and follow-up data should be presented. Lastly, we discuss the implications of the design, analytical and presentational issues covered. Summary Difficulties in interpreting the results of factorial trials if an influential interaction is observed is the cost of the potential for efficient, simultaneous consideration of two or more interventions. Factorial trials can in principle be designed to have adequate power to detect realistic interactions, and in any case they are the only design that allows such effects to be investigated.

    Full Text Available BACKGROUND: We have previously reported the results of Deep Brain Stimulation (DBS of the antero-medial globus pallidus interna (GPi for severe Tourette Syndrome (TS in 11 patients. We extend this case series to 17 patients and a longer follow-up to a maximum of 46 months. METHODS: 17 patients (14 male; mean age 29.1 years, range 17-51 years with severe and medically intractable TS were implanted with Medtronic quadripolar electrodes bilaterally in the antero-medial GPi. The primary outcome measure was the Yale Global Tic Severity Scale (YGTSS. Secondary outcome measures included the Yale-Brown Obsessive Compulsive Scale, Hamilton Depression Rating Scale, Gilles de la Tourette Quality of Life Scale and Global Assessment of Functioning. Follow up was at one month, three months and finally at a mean 24.1 months (range 8-46 months following surgery. RESULTS: Overall, there was a 48.3% reduction in motor tics and a 41.3% reduction in phonic tics at one month, and this improvement was maintained at final follow-up. 12 out of 17 (70.6% patients had a>50% reduction in YGTSS score at final follow up. Only 8 patients required ongoing pharmacotherapy for tics post-surgery. Patients improved significantly on all secondary measures. Adverse consequences included lead breakage in 4 patients, infection (1, transient anxiety (2, dizziness (1, poor balance (1 and worsening of stuttering (1. CONCLUSIONS: This case series provides further support that antero-medial GPi DBS is an effective and well tolerated treatment for a subgroup of severe TS, with benefits sustained up to 4 years.

  7. The pars interna/media anatomy and histology in the human larynx.

    2007-01-01

    The pars interna/media (PIM) is a small muscle found in the human larynx that has not been successfully described in contemporary literature on laryngeal structure. The objective of this study was to describe the PIM's anatomy in detail. Thirteen human larynges obtained from postmortem examination were cleaned and preserved. Exposure of the PIM was through a lateral disarticulation of the cricothyroid joint and reflection of the cricothyroid muscle and the thyroid lamina. In the human, the PIM was found to be strap-like in form and to have two bellies with attachments to the medial surface of the thyroid cartilage at the root of the inferior horn and anteriosuperior cricoid arch. It appears to be innervated by a middle division, vestibular branch, of the internal superior laryngeal nerve. The average fiber diameter is 40 mum. Its type 1-to-type 2 fiber ratio places it within the range of other intrinsic laryngeal muscles. A muscle spindle was identified in medial bundle at the PIM's thyroid attachment. Thyroid medial surface attachment is within few millimeters of the muscular process of the arytenoid cartilage. These data show that the PIM is a robust muscle and deserves attention anatomically. Its orientation within the thyroid and nonrecurrent laryngeal nerve innervations of the human PIM may place it in the vocal fold tensor group rather than the laryngeal sphincter group. It is possible the PIM reports on cricothyroid distance and right versus left cricothyroid joint stresses. Electromyographic examination of the PIM in the Rhesus larynx may help elucidate its physiology to elaborate its human physiology. Copyright 2007 S. Karger AG, Basel.

    {sup 18}F-Fluoride PET/CT is a relatively undervalued diagnostic test to measure bone metabolism in bone diseases. Hyperostosis cranialis interna (HCI) is a (hereditary) bone disease characterised by endosteal hyperostosis and osteosclerosis of the skull and the skull base. Bone overgrowth causes entrapment and dysfunction of several cranial nerves. The aim of this study is to compare standardised uptake values (SUVs) at different sites in order to quantify bone metabolism in the affected anatomical regions in HCI patients. Nine affected family members, seven non-affected family members and nine non-HCI non-family members underwent {sup 18}F-fluoride PET/CT scans. SUVs were systematically measured in the different regions of interest: frontal bone, sphenoid bone, petrous bone and clivus. Moreover, the average {sup 18}F-fluoride uptake in the entire skull was measured by assessing the uptake in axial slides. Visual assessment of the PET scans of affected individuals was performed to discover the process of disturbed bone metabolism in HCI. {sup 18}F-Fluoride uptake is statistically significantly higher in the sphenoid bone and clivus regions of affected family members. Visual assessment of the scans of HCI patients is relevant in detecting disease severity and the pattern of disturbed bone metabolism throughout life. {sup 18}F-Fluoride PET/CT is useful in quantifying the metabolic activity in HCI and provides information about the process of disturbed bone metabolism in this specific disorder. Limitations are a narrow window between normal and pathological activity and the influence of age. This study emphasises that {sup 18}F-fluoride PET/CT may also be a promising diagnostic tool for other metabolic bone disorders, even those with an indolent course. (orig.)

    Pilot infrastructures are becoming prominent players in the Grid environment. One of the major advantages is represented by the reduced effort required by the user communities (also known as Virtual Organizations or VOs) due to the outsourcing of the Grid interfacing services, i.e. the pilot factory, to Grid experts. One such pilot factory, based on the glideinWMS pilot infrastructure, is being operated by the Open Science Grid at University of California San Diego (UCSD). This pilot factory is serving multiple VOs from several scientific domains. Currently the three major clients are the analysis operations of the HEP experiment CMS, the community VO HCC, which serves mostly math, biology and computer science users, and the structural biology VO NEBioGrid. The UCSD glidein factory allows the served VOs to use Grid resources distributed over 150 sites in North and South America, in Europe, and in Asia. This paper presents the steps taken to create a production quality pilot factory, together with the challenges encountered along the road.

    The construction of the B-factory, designed to generate B-mesons by asymmetric electron-positron collision for high-energy physics research, is progressing rapidly toward completion scheduled for spring 1999. The B-factory is expected to resolve the violation of symmetry between matter and anti-matter by experiments on B-meson decays. From the spring 1995, IHI has participated in the construction of the BELLE (the French word for beauty) detector, which is the only detector for the B-factory. IHI performed the high precision fabrication, installation, and measurement of the main components for the BELLE detector, for example, iron yoke structure, containers, and supports for the inner detectors.

    Godfrey, D. E.

    1985-01-01

    The features of factories and manufacturing techniques and tools of the near future are discussed. The spur to incorporate new technologies on the factory floor will originate in management, who must guide the interfacing of computer-enhanced equipment with traditional manpower, materials and machines. Electronic control with responsiveness and flexibility will be the key concept in an integrated approach to processing materials. Microprocessor controlled laser and fluid cutters add accuracy to cutting operations. Unattended operation will become feasible when automated inspection is added to a work station through developments in robot vision. Optimum shop management will be achieved through AI programming of parts manufacturing, optimized work flows, and cost accounting. The automation enhancements will allow designers to affect directly parts being produced on the factory floor.

    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.

    Objective: To find the effect of the fertilizer factory environment on serum prostatic specific antigen (PSA) levels. Subjects and Methods: A total of 205 workers, all male, of Pak Arab Fertilizer Factory, Multan had their prostatic specific antigen (PSA) estimated. The age of the workers varied between 22 to 65 years (mean age= 48.3 plus minus 8.5 years). The people belonged to various working groups and most of them were on normal Pakistani diet. They had been residing/working in the factory area for a period varying from 5 to 30 years. PSA levels were also estimated in 118 normal persons to serve as a control group. The age of these persons varied from 19 to 64 years. These were mostly hospital staff and general public not residing in the factory area and had no history of prostatic disease. Sensitive and specific immunoradiometric assay techniques were applied to measure the PSA concentrations in serum. Results: Observed PSA levels in this population were between 0.2 and 11.5 ng/ml. Overall mean PSA level was 1.9 plus minus 0.84 ng PSA/ml. Mean PSA level observed in control group was 0.73 plus minus 0.64 ng/ml (upper 95% limit was 3.2 ng/ml). Comparison of PSA levels of factory workers with values in normal subjects showed that 9 out of 205 male workers (4.3% of total) had significantly elevated levels of PSA. In 2 workers (1 % of total) observed PSA levels were above 10 ng/ml. The levels above this limit are most commonly observed in the cancer patients. Conclusion: A significant proportion of the workers of the fertilizer factory are at risk of malignant and non-malignant disease of the prostate. (author)

    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).

Quando avaliada de forma isolada, a mortalidade é uma medida insuficiente do resultado na Unidade de Terapia Intensiva (UTI; o tempo de internação pode ser uma medida indireta do resultado relacionado com a morbidade. O objetivo do presente estudo foi avaliar a incidência e os fatores preditivos para mortalidade e tempo de internação dos pacientes admitidos numa UTI cirúrgica. MÉTODO: Participaram deste estudo prospectivo, realizado, entre abril e julho de 2004, todos os 185 pacientes submetidos a procedimentos programados ou de emergência, admitidos numa UTI cirúrgica. Foram registrados os seguintes parâmetros: idade, sexo, altura e peso, temperatura central estado físico segundo a ASA, tipo de intervenção cirúrgica, porte cirúrgico, técnica anestésica, quantidade e qualidade de fluídos administrados durante a anestesia, monitorização da temperatura ou de técnica de aquecimento corporal peri-operatório, duração da anestesia, tempo de permanência na UTI e no hospital e escore SAPS II. RESULTADOS: O tempo médio de internação na UTI foi de 4,09 ± 10,23 dias. Fatores de risco significativos para permanências mais prolongadas na UTI foram o valor do escore SAPS II, estado físico ASA, quantidade administrada, durante a intervenção cirúrgica, de colóides, unidades de plasma fresco e unidades de concentrados de hemáceas. Quatorze pacientes (7,60% morreram durante a internação na UTI e 29 (15,70% morreram durante a internação hospitalar. Fatores de risco independentes de mortalidade com diferença estatística significativa foram intervenções cirúrgicas de emergência, de grande porte, escores altos SAPS II, permanência prolongada na UTI e no hospital.

Materiales y métodos. Tras las sesiones presenciales, el material docente se deposita en la página web o campus virtual de la asignatura, a partir del cual los estudiantes responden a seis cuestionarios. Resultados. En el curso 2008-2009 se matricularon 61 alumnos de cuarto a sexto curso. Veintisiete alumnos (44,26% respondieron correctamente a más de la mitad de las preguntas, el 31,15% no alcanzó esta cifra y el 24,59% no completó el programa de evaluaciones. Las puntuaciones más altas se han dado de las pruebas funcionales respiratorias, y las más bajas, en la evaluación de la radiografía de tórax. Conclusiones. No es fácil la evaluación de competencias clínicas. El coste de realización de las pruebas y la resistencia de los estudiantes a ser evaluados quedan soslayados en esta experiencia, donde los estudiantes se matriculan voluntariamente. La sencillez del proyecto permitiría evaluar en competencias clínicas a todos los estudiantes de la facultad en los cursos clínicos cuando aún es posible la formación. Una vez comprobado que los estudiantes tienen una buena aceptación del sistema propuesto, se podría diseñar un sistema de acceso a créditos docentes y un plan de formación específica en las materias no superadas.

  3. Medida Socioeducativa de Internação: dos Corpos Dóceis às Vidas Nuas

    Andrea Cristina Coelho Scisleski

    Full Text Available O presente artigo tem como objetivo a problematização dos modos pelos quais a tecnologia disciplinar, presente nas medidas socioeducativas de internação direcionadas aos jovens em conflito com a lei, vem sendo operacionalizada. Tomamos como fio condutor as reflexões de Michel Foucault e Giorgio Agamben para problematizar a vida enquanto objeto político a ser governado para determinado fim e que sofre intervenções não apenas para seu fortalecimento, mas que levam à desproteção jurídica e à morte política, ou mesmo biológica. A investigação se desenvolveu em três momentos metodológicos: oitiva de audiências na Vara da Infância e da Juventude, visita a uma unidade educacional de internação e leitura de processos jurídicos e das normativas legais voltadas para a população em questão. Assim, por meio do que encontramos na pesquisa, entende-se que a tecnologia disciplinar, do modo que vem sendo utilizada nas medidas socioeducativas de internação, assemelha-se mais a um dispositivo de controle com o objetivo meramente de docilizá-los, reduzindo o sujeito à vida nua; isto é, como mero corpo biológico que sofre efeitos de uma ação, do que propriamente um método socioeducativo como estabelecem o Estatuto da Criança e do Adolescente e o Sistema Nacional de Atendimento Socioeducativo.

    Full Text Available Abstract. Medium-sized manufacturing industry in Indonesia is overwhelmed by certain challenges: high-cost economy, significant changes in information technology, and dynamic market and demand. All of these challenges affect gradually or directly to the sustainability of the industry. This preliminary study aims to conceptualize the importance of ‘digital factory’ implementation to dealing with sustainability issues. Previous studies showed that the implementation of digital factory, in the context of large-sized technological-based manufacturing enterprises, has been proved to increase the efficiency of product development process and production process, in term of time and cost. This study tries to identify several key issues to support the implementation of digital factory: data and information completeness, hardware and software availability, and operators’ skill and experience in conducting simulation. The relationships of the variables are modelled and analyzed using SmartPLS. This preliminary study found that, concurrently, data and information completeness, hardware and software availability, and operators’ skill and experience in conducting simulation have significant effect to digital factory implementation, as well as the enterprise’s sustainability (better product design and improvement (innovativeness, more efficient in design and simulation of production process (efficiency, and better capability to deal with dynamic demand (adaptiveness.

    2013-12-17

    This paper proposes a real-time method to carry out the monitoring of factory zone temperatures, humidity and air quality using smart phones. At the same time, the system detects possible flames, and analyzes and monitors electrical load. The monitoring also includes detecting the vibrations of operating machinery in the factory area. The research proposes using ZigBee and Wi-Fi protocol intelligent monitoring system integration within the entire plant framework. The sensors on the factory site deliver messages and real-time sensing data to an integrated embedded systems via the ZigBee protocol. The integrated embedded system is built by the open-source 32-bit ARM (Advanced RISC Machine) core Arduino Due module, where the network control codes are built in for the ARM chipset integrated controller. The intelligent integrated controller is able to instantly provide numerical analysis results according to the received data from the ZigBee sensors. The Android APP and web-based platform are used to show measurement results. The built-up system will transfer these results to a specified cloud device using the TCP/IP protocol. Finally, the Fast Fourier Transform (FFT) approach is used to analyze the power loads in the factory zones. Moreover, Near Field Communication (NFC) technology is used to carry out the actual electricity load experiments using smart phones.

    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.

  12. Manufacturing data analytics using a virtual factory representation.

    Science.gov (United States)

    Jain, Sanjay; Shao, Guodong; Shin, Seung-Jun

    2017-01-01

    Large manufacturers have been using simulation to support decision-making for design and production. However, with the advancement of technologies and the emergence of big data, simulation can be utilised to perform and support data analytics for associated performance gains. This requires not only significant model development expertise, but also huge data collection and analysis efforts. This paper presents an approach within the frameworks of Design Science Research Methodology and prototyping to address the challenge of increasing the use of modelling, simulation and data analytics in manufacturing via reduction of the development effort. The use of manufacturing simulation models is presented as data analytics applications themselves and for supporting other data analytics applications by serving as data generators and as a tool for validation. The virtual factory concept is presented as the vehicle for manufacturing modelling and simulation. Virtual factory goes beyond traditional simulation models of factories to include multi-resolution modelling capabilities and thus allowing analysis at varying levels of detail. A path is proposed for implementation of the virtual factory concept that builds on developments in technologies and standards. A virtual machine prototype is provided as a demonstration of the use of a virtual representation for manufacturing data analytics.

  14. Limit values in special agreements between factories and sewage works

    International Nuclear Information System (INIS)

    Lundstroem, Yrjoe

    1987-01-01

    The operation of sewage works is controlled in Finland by the water and health authorities. These authorities set special quality demands for the effluent from sewage treatment plants into the recipient. Also other wastes from treatment plants, mainly sludges, have special regulations and operational target values. Sewage works have to achieve the aim goals and limit values set. In order to fulfill the regulations, sewage works impose such limit values on factory wastewaters that there will be no problems at the treatment plants. Sewage works can act in two ways: - require the factory to operate in such a way that the limit values are not exceeded, - the factory pays a certain sum of money to the sewage works, which takes care of the whole problem. It can be said in general, that it is not possible to get rid of harmful substances by payment to the sewage works if the substances cause treatment problems or problems in sludge disposal. If the factory produces wastewater that contains a higher organic load, more suspended solids or a higher nutrient load than normal sanitary wastewater, the problem is most often solved by paying an extra fee to the sewage works

    Full Text Available A "Plant factory" is one of the advanced facilities for vegetable cultivation in an artificially controlled environment, i.e., temperature, humidity, and CO2 concentration are controlled. Recently, it has become popular in Japan, USA, China and others. However, there are some problems to overcome before they become widespread. A project to develop a specific plant factory called the "Okinawa-type plant factory" has been funded by the Okinawa Prefecture. It addresses the severe environmental and social conditions of Okinawa. The main goal of the project was to reduce energy consumption by 30%. To achieve this, three methods were investigated using solar energy and LED lamps, since this plant factory used artificial illumination. Forty foot reefer containers were employed for the cultivation room, and insulation panels were partially used. Solar energy was used for lighting and air-conditioning. Solar energy was converted to thermal energy for air-conditioning using heat collecting panels. Hot water of 75-85 oC obtained by the collector was used for adsorption refrigeration. Sunlight was introduced in the cultivation room from the skylight windows. DC to DC system was also employed for photovoltaic utilization. The use of solar energy and LED lamps are effective to reduce energy consumption. A 30% reduction in energy use was achieved.

  11. Phenomenology of neutrino oscillations at the neutrino factory

    International Nuclear Information System (INIS)

    Tang, Jian

    2011-01-01

    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 μ + → ν e → ν μ → μ - and the right-charge muons coming from the chain μ + → anti ν μ → anti ν μ → μ - (similar to μ - chains), where ν e → ν μ and anti ν μ → anti ν μ 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 τ decays, generated by appearance channels ν μ → ν τ and ν e → ν τ , on the discovery reaches of the mass orderings, the leptonic CP violation, and the non-zero θ 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 effects of one additional massive sterile neutrino are discussed in the context of a combined short and long baseline setup. It is found that near detectors can provide the required sensitivity at the

Os procedimentos metodológicos seguiram a linha qualitativa, por meio da pesquisa descritiva e aplicada. Foram entrevistadas sete das maiores empresas catarinenses em número de funcionários. Utilizou-se análise documental e de conteúdo. Quanto aos resultados, a consultoria interna auxilia principalmente nas etapas de socialização e externalização do conhecimento. Além disso, se implementada na sua totalidade e dada autonomia ao consultor interno, permite uma maior interação nos níveis individual, grupal e organizacional descritos por Sabbag (2007. Assim, pode-se perceber que as empresas que possuem maior grau de autonomia, bem como maior nível de implementação são aquelas que os processos são mais compartilhados, socializados e internalizados pelos funcionários. Dessa forma, pode-se afirmar que, nas empresas analisadas, o desenvolvimento dos processos de CIRH catalisa os resultados da Gestão do Conhecimento nas mesmas.

    Galaxy is a software application supporting high-throughput biology analyses and work flows, available as a free on-line service or as source code for local deployment. New tools can be written to extend Galaxy, and these can be shared using public Galaxy Tool Shed (GTS) repositories, but converting even simple scripts into tools requires effort from a skilled developer. The Tool Factory is a novel Galaxy tool that automates the generation of all code needed to execute user-supplied scripts, and wraps them into new Galaxy tools for upload to a GTS, ready for review and installation through the Galaxy administrative interface. The Galaxy administrative interface supports automated installation from the main GTS. Source code and support are available at the project website, https://bitbucket.org/fubar/galaxytoolfactory. The Tool Factory is implemented as an installable Galaxy tool. ross.lazarus@channing.harvard.edu.

  14. Physics prospects for the SLAC B-Factory

    Energy Technology Data Exchange (ETDEWEB)

    Coward, D.H.

    1996-11-01

    CP violation has been an enigma since its discovery in the decays of neutral kaons in 1964. The present version of the Standard Model can accommodate CP violation by means of a non-zero phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. However, CP violation in the kaon system occurs at the part per mille level and the Standard Model`s predictions for CP violation have not been conclusively tested. In contrast to the kaon system, B-mesons decay into a variety of final states, many of which could exhibit CP violation and therefore offer multiple tests of the Standard Model. Several large efforts currently are in progress to create dedicated experiments or factories which will provide large quantities of B-mesons which, in turn, should give large numbers of CP-violating decays. Here, a very brief presentation of the physics prospects for the SLAC B-Factory, now under construction, is presented.

    2004-01-05

    The importance of a Super-B Factory in the search for New Physics, in particular, due to CP-od phase(s) from physics beyond the Standard Model is surveyed. The first point to emphasize is that we know now how to directly measure all three angles of the unitarity triangle very cleanly, i. e. without theoretical assumptions with irreducible theory error {le} 1%; however this requires much more luminosity than is currently available at B-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 B-physics are small.

    2009-01-01

    There is considerable interest in the use of muon beams to create either an intense source of decay neutrinos aimed at a detector located 3000-7500 km away (a Neutrino Factory), or a Muon Collider that produces high-luminosity collisions at the energy frontier. R and D aimed at producing these facilities has been under way for more than 10 years. This paper will review experimental results from MuCool, MERIT, and MICE and indicate the extent to which they will provide proof-of-principle demonstrations of the key technologies required for a Neutrino Factory or Muon Collider. Progress in constructing components for the MICE experiment will also be described.

    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.

    Zhang, Rong; Liu, Tong; Ma, Jianshe

    2017-03-01

    In recent years, climate change has become a focus issue all over the world. Many scientific studies have confirmed the relationship between the emission of greenhouse gas such as carbon dioxide and global climate change. Reducing the emission of greenhouse gas is an effective way to solve the problem of climate change. This paper presents a new method for reducing carbon emissions: using the photosynthesis of plants to achieve carbon fixation in plant factory. In order to verify the feasibility of this method, we built a closed artificial light plant factory adopting LED lighting to conduct the experiment of carbon dioxide enrichment. The results shows that the production of the plants increased by 20%-25% and the plants fixed a considerable amount of carbon dioxide by increasing the concentration of carbon dioxide in the environment to 1000 ppm.

    Cervera, A.; Dydak, F.; Gomez Cadenas, J.J.

    2000-01-01

    The physics opportunities of the neutrino factory have been the subject of a number of recent studies. It was shown that sensitive measurements of the angle θ 13 , of MSW effects, and of the sign of the atmospheric mass difference Δm 23 2 are possible, and even CP violation in the neutrino mixing matrix may be within reach. The focus of interest is the oscillation ν e →ν μ , which leads in the well-defined neutrino beam of the neutrino factory to 'wrong-sign' muon events. In this paper, we show that a large magnetic detector will be capable of detecting with high efficiency and small backgrounds such wrong-sign muon events. We present a conceptual design of the apparatus and its performance. Various backgrounds are analysed and we demonstrate that they can be sufficiently suppressed by appropriate cuts. We illustrate the performance of the large magnetic detector by its sensitivity to the angle θ 13

    Full Text Available ABSTRACT High concentrations of airborne dust are observed during the cutting of medium density fiberboard (MDF boards. This dust, at first considered just uncomfortable for workers, may be harmful to their health. The objective of this work was to evaluate the concentration of airborne dust during the cutting of medium density fiberboard (MDF. The experiment was developed in the MDF cutting sector of three furniture factories located in the city of Lavras/MG. The results showed that the mean concentrations of total dust suspended in these three furniture factories were above the tolerance limit set by the American Conference of Governmental Industrial Hygienists (ACGIH, giving evidence of a serious problem in these companies related to this type of risk agent.

    Microbes in different aged workshops play important roles in the flavor formation of Jinhua ham. However, microbial diversity, community structure and age related changes in workshops are poorly understood. The microbial community structure and diversity in Jinhua ham produced in factories that have 5, 15, and 30 years of history in processing hams were compared using the pyrosequencing technique. Results showed that 571,703 high-quality sequences were obtained and located in 242 genera belonging to 18 phyla. Bacterial diversity and microbial community structure were significantly different with the years of workshops. Three-phase model to characterize the changes of ham microbial communities was proposed. Gas chromatography-mass spectrometry assays indicated that the hams produced in different aged workshops have great differences in number and relative contents of volatiles compounds. These results suggest that different aged factories could form special and well-balanced microbial diversity, which may contribute to the unique flavor characteristics in Jinhua ham.

    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 Logistic considers the complete process since the determination of possible demand, production planning, materials procurement, production control and delivery of final products to customer. This complete process is managed in all the scope under the same department called Planning and Logistic. This integration, some times really complex, has allowed to Enusa factory control all the key aspects that allow its running completely, considering the synergy's and important advantages to solve different problems. This article describes how we work of the main areas of procurement, production planning and control, fuel delivery and project planning of improvements on equipment's and factory systems, with an integrated management of all of them under the same direction.

    1979-01-01

    A possibility of usage of accelerators of neutron as well as meson factories is considered. Parameters of linear and cyclic accelerators are given, which are employed as meson factories and as base for developing intense neutron generators. It is emphasized that the principal aim of developing neutron generators on the base of high current proton accelerators is production of intense neutron fluxes with a present energy spectrum. Production of tens-and-hundreds milliampere currents at the energy of 800-1000 MeV is considered at present for two types of accelerating facilities viz. linear accelerators under continuous operating conditions and cyclotrons with strong focusing. Quantitative evaluations of developing high-efficiency linear and cyclic accelerators are considered. The basic parameters of an ccelerating complex are given, viz. linear accelerator-injector and 800 MeV isochronous cyclotron. The main problems associated with their realization are listed [ru

    Growing market turbulences and shorter product life cycles require a continuous adaptation of factory structures resulting in a continuous factory planning process. Therefore a new framework is developed which focuses on configuration and data management process integration. This enable an online system performance evaluation based on continuous availability of current data. The use of this framework is especially helpful and will guarantee high cost and time savings, when used in the early stages of the planning, called the concept or rough planning phase. The new framework is supported by a planning round table as a tool for team-based configuration processes integrating the knowledge of all persons involved in planning processes. A case study conducted at a German company shows the advantages which can be achieved by implementing the new framework and methods.

    Meschtscherjakov, Alexander; Reitberger, Wolfgang; Pöhr, Florian; Tscheligi, Manfred

    In this paper we introduce the context of a semiconductor factory as a promising area for the application of innovative interaction approaches. In order to increase efficiency ambient persuasive interfaces, which influence the operators' behaviour to perform in an optimized way, could constitute a potential strategy. We present insights gained from qualitative studies conducted in a specific semiconductor factory and provide a description of typical work processes and already deployed interfaces in this context. These findings informed the design of a prototype of an ambient persuasive interface within this realm - the "Operator Guide". Its overall aim is to improve work efficiency, while still maintaining a minimal error rate. We provide a detailed description of the Operator Guide along with an outlook of the next steps within a user-centered design approach.

  10. Unifying logarithmic and factorial behavior in high-energy scattering

    Cornwall, J.M.; Morris, D.A.

    1995-01-01

    The elegant instanton calculus of Lipatov and others used to find factorially divergent behavior (g N N exclamation point) for N g much-gt 1 in gφ 4 perturbation theory is strictly only applicable when all external momenta vanish; a description of high-energy 2→N scattering with N massive particles is beyond the scope of such techniques. On the other hand, a standard multiperipheral treatment of scattering with its emphasis on leading logarithms gives a reasonable picture of high-energy behavior but does not result in factorial divergences. Using a straightforward graphical analysis we present a unified picture of both these phenomena as they occur in the two-particle total cross section of gφ 4 theory. We do not attempt to tame the unitarity violations associated with either multiperipheralism or the Lipatov technique at strong coupling

    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 proposed B factory accelerator facilities will require active feedback systems to control multibunch instabilities. These feedback systems must operate in machines with thousands of circulating bunches and with short (2--4 ns) interbunch intervals. The functional requirements for transverse (betatron) and longitudinal (synchrotron) feedback systems are presented. Several possible implementation options are discussed and system requirements developed. Conceptual designs are presented for the PEP II transverse and longitudinal feedback systems

A factorial design is here applied to plan an experimental series where, in particular, vacuum assisted mouldings are carried out in a circular shaped mould. One result is that the electrical insulation can be considerably improved by choosing optimal...

  18. Comments on particle identification at the B factory

    1992-01-01

    The importance of particle identification at an asymmetric B Factory is discussed, and the general status of a number of particle identification technologies which might be included in B Factory detectors is briefly reviewed. It is generally agreed that high quality hadronic particle identification is fundamental to the central mission of understanding CP violation at the B Factory, but there is as yet no clear open-quotes consensusclose quotes solution for such a detector. In a sense, this lack of a particle identification solution is a matter of definition. There is, in fact, a perfectly reasonable, open-quotes conventional technologyclose quotes, particle identification system which makes use of a large tracking chamber with excellent (i.e., relativistic rise quality) dE/dx surrounded by a good TOF with a rather long flight path. The chamber must be rather large (around 2 meters in outer radius) and perhaps high pressure as well, but similar devices are rather well understood and it would appear to be possible to meet the particle identification performance required at B Factory momenta. This solution has not been embraced by any of the detector groups, however, because of the effect it has on the electromagnetic calorimetry. open-quotes Everyoneclose quotes wants high quality calorimetry (such as can be provided by CsI crystals), but such devices cost a great deal per unit volume, and the cost scales roughly like the inner radius squared. Moreover, no one wants to see the high quality (expensive) calorimetry compromised by excessive mass in front. Thus, the essence of the particle identification problem is that there is no approximately massless, very thin particle identification device known with adequate performance. Of course, it might equally well be said that there is no high quality calorimeter known which is sufficiently cost-effective to be placed outside an appropriately sized tracking plus particle identification system

    A conceptual design is developed for control of the Kaon Factory booster rf accelerating fields. This design addresses control of cavity: tuning, voltage amplitude, and voltage phase angle. Time-domain simulations were developed to evaluate the proposed controllers. These simulations indicate that adequate tuning performance can be obtained with the combination of adaptive feed forward and proportional feedback control. Voltage amplitude and voltage phase can be adequately controlled using non-adaptive feed forward and proportional feedback control. (Author) (figs., tabs.)

Como paso previo, sin embargo, Menem debió vencer en unas elecciones internas en las que partía, en principio, en clara desventaja ante el favorito Antonio Cafiero, gobernador de la provincia de Buenos Aires y líder de la llamada Renovación peronista. La sorprendente victoria de Menem en 1988 ha sido explicada comúnmente como fruto de la reacción de la sociedad a la clase política, en el contexto de crisis que atravesaba el país, o bien como producto de los límites e insuficiencias de la línea cafierista. Sin desconocer estos enfoques, en este texto abordamos el problema desde la perspectiva interna del peronismo y del propio Menem, describiendo su labor de acumulación y reestructuración de los sectores más ortodoxos del partido, apartados por el avance de la Renovación.

    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. Disk servers optimized for cost per Gbyte serve terabytes of processed data, while servers optimized for disk read speed run SQLServer software to process queries on the catalogs. This factory produced data for the SDSS Early Data Release in June 2001, and it is currently producing Data Release One, scheduled for January 2003.

    Research purpose: The purpose of the study was to assess the degree of factorial invariance across race and gender by using a sample of aspiring chartered accountants. Motivation for the study: Previous research on the hope construct and associated measuring instruments have been conducted, using homogenous samples from Westernised cultures. Researchers need to be careful to assume that hope looks and behaves in exactly the same manner across cultures and groups. Research approach, design and method: A cross-sectional quantitative research design was used. A sample of 295 aspiring chartered accountants participated in the study. Exploratory factor analysis was used to determine the degree of factor similarity across groups, utilising Tucker’s coefficient of congruence. To supplement the exploratory factor analysis, a series of increasingly restrictive multi-group analyses were conducted to test the invariance of model parameters across the groups. Main findings: No significant differences were found in the factor patterns for the agency and pathways factors for (1 the white and designated groups and (2 females and males. Practical/managerial implications: Evidence related to factorial invariance was found. This should inform researchers and practitioners that both pathways and agency look similar across racial and gender groups. Contribution/value-add: Researchers are urged to use various statistical techniques, in combination, to determine the degree of factorial invariance across groups.

    Full Text Available Background. Chronic respiratory symptoms including chronic cough, chronic phlegm, wheezing, shortness of breath, and chest pain are manifestations of respiratory problems which are mainly evolved as a result of occupational exposures. This study aims to assess determinants of chronic respiratory symptoms among pharmaceutical factory workers. Methods. A case control study was carried out among 453 pharmaceutical factory workers with 151 cases and 302 controls. Data was collected using pretested and structured questionnaire. The data was analyzed using descriptive statistics and bivariate and multivariate analysis. Result. Previous history of chronic respiratory diseases (AOR = 3.36, 95% CI = 1.85–6.12, family history of chronic respiratory diseases (AOR = 2.55, 95% CI = 1.51–4.32, previous dusty working environment (AOR = 2.26, 95% CI = 1.07–4.78, ever smoking (AOR = 3.66, 95% CI = 1.05–12.72, and service years (AOR = 1.86, 95% CI = 1.16–2.99 showed statistically significant association with chronic respiratory symptoms. Conclusion. Previous history of respiratory diseases, family history of chronic respiratory diseases, previous dusty working environment, smoking, and service years were determinants of chronic respiratory symptoms. Public health endeavors to prevent the burden of chronic respiratory symptoms among pharmaceutical factory workers should target the reduction of adverse workplace exposures and discouragement of smoking.

    Recent results from long baseline neutrino oscillation experiments point towards a non-zero value of θ 13 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 θ 13 . We find that in case of small θ 13 , baselines of about 2500 to 5000 km is the optimal choice for the CP violation measurement with E μ as low as 12 GeV can be considered. However, for large θ 13 , 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.

    Commuting transportation is one of the important factors in the administration of safety management in industries. Most workers commute to work by car and are certain to make use of highways, mainly because of the special condition of factory locations. In this study, we investigated the effect of communicating by car on the health of factory workers. The proportion of males was significantly higher in the highway (HW) group than in the non-highway (NHW) group, and the former was younger than the latter. BMI, systolic blood pressure, diastolic blood pressure, and total cholesterol deteriorated significantly in the NHW group after 5-year periodic medical checkups. However, in the HW group, those factors did not change except for systolic blood pressure and significant improvements in triglyceride. The percentage of those who follow a good lifestyle regarding excise and nutrition, and have a solution for stress, was lower in the HW group than in the NHW group. Nevertheless, the percentage of those who did not feel stress was significantly higher in the HW group than in the NHW group, suggesting a stress-relieving effect of highway driving. Highway driving might have an unexpectedly good impact on the health of factory workers.

    Lifestyle factors, sometimes associated with physical health and mortality, have also been known to be associated with mental health status. This study seeks to correlate behavioral lifestyles with major components of mental health among Japanese factory workers. We administered the 28-item version of the General Health Questionnaire (GHQ-28) and a questionnaire concerning eight personal health practices to 2,132 male and 668 female factory workers at a camera-manufacturing company in Japan. There were strong negative relationships of a higher total number of favorable lifestyles as indicated by the Health Practice Index (HPI) to psychological distress and its components: somatic symptoms, anxiety-insomnia, and social dysfunction. After controlling for the effects of confounding factors that included age, marital status, and somatic condition, multiple logistic regression analysis indicated that five of the eight health factors among male workers--mental stress, nutritional balance, eating breakfast regularly, physical exercise, and working hours--were significantly related to the grade of psychological distress or its three components. Among female workers, five health practices, i.e., mental stress, physical exercise, sleeping hours, working hours, and cigarette smoking, were significantly associated with the grade of psychological distress or its three components. Good health practices might be individually and as a whole associated with better mental health status in factory workers.

    Full Text Available A anatomia e a morfologia interna do tronco encefálico (TE do macaco-prego (Cebus apella foram descritas com base nas observações feitas em troncos encefálicos de macacos adultos. Seis macacos Cebus apella adultos foram utilizados para as observações anatômicas. Para os estudos da morfologia interna os TE foram cortados seriadamente em seis níveis diferentes: decussação piramidal, porção superior da oliva, porção inferior da oliva, ponte, colículo superior e colículo inferior. Após esse procedimento eles foram corados com a técnica de Mulligan modificada por nós. Nossos resultados mostram que o TE de Cebus apella é caracterizado pela presença do sulco bulbo-pontino, aumento do tamanho do TE, especialmente da medula oblonga, com consequente lateralização do corpo trapezoide, presença do sulco ântero-lateral separando as pirâmides das olivas; desenvolvimento expressivo do corpo trapezoide, da ponte, dos núcleos da ponte e do pedúnculo cerebral. Estes resultados são consistentes com descrições prévias para outros primatas na literatura e sugerem que a organização e desenvolvimento do TE exibe semelhanças com primatas superiores, incluindo o homem, o que reflete as habilidades motoras da espécie estudada.

    Full Text Available No que tange a comprovada eficácia da drenagem pleural fechada, grande controvérsia ainda persiste em relação ao uso associado da antibioticoterapia. Os autores estudaram 167 pacientes, com trauma isolado do tórax, com objetivo de avaliar a importância do uso do antibiótico sobre o tempo de internação pós-drenagem pleural fechada. Dois grupos de pacientes foram incluídos num estudo longitudinal e prospectivo de acompanhamento de coortes. O grupo controle incluiu 104 pacientes sem uso da antibioticoterapia; no grupo experimental, 63 pacientes receberam a cefalotina sódica no pós-operatório (500 mg IV - 6/6 h. Entre os pacientes estudados, 12 (7.2% apresentavam trauma fechado; 98 (58.6%, ferimento por arma branca; 41 (24.6% ferida por projétil de arma de fogo e, 16 (9.6% lesões por outros agentes vulnerantes. Entre os pacientes do grupo controle o tempo médio de permanência hospitalar foi de 5.7± 3.2 dias e, no grupo com antibiótico, 5.7± 2.9 dias. Os resultados mostraram que nos pacientes que não receberam antibiótico e evoluíram com algum tipo de complicação pleuropulmonar, o tempo de internação foi, em média, 3.2 dias maior que nos demais.

Especially of individual from grave no. 2/2008 – preserved cranium showed marks of endocranial hyperostosis (stage B according Hershkovitz et al. 1999. Hyperostosis frontalis interna (HFI is an overgrowth of bony tissue on the inner plate of the frontal bone of the calvaria, the irregular thickening of the endocranium (may be 1 cm or thicker. It is typically bilateral and symmetrical, and may extend to involve the parietal bones. It was first described in 1765 by Morgagni and Santorini as an obesity and virilism associated with thickening of internal table of the frontal bone called hyperostosis frontalis interna. HFI appears more commonly in women than in men, with an estimated male:female ratio 1:9, usually in age 35 years and older women. In modern population this condition is most prevalent in postmenopausal females, with frequencies of 40 – 62% reported, in general population, composed of males and females of different ages HFI affects 3 – 15% of individuals. In contrast, HFI is rarely reported in an archeological context. Using an anthropomorphological and paleopathological examination of the skeletal remains we realized that this women was in age category adultus II (30 – 39 years or older, her stature was cca 151.875 cm and she also suffered from DISH, healed fracture of styloid process of right ulna, osteoarthrosis of humeral and femoral heads and spondylosis.

Trata-se de um estudo exploratório-descritivo de abordagem qualitativa, desenvolvido na Unidade de Terapia Intensiva (UTI de um hospital referência da zona Norte do Ceará. Os sujeitos do estudo foram quatorze familiares de pacientes internados na UTI. Os dados foram coletados durante os meses de novembro e dezembro de 2015. A análise das informações permitiu traçar o perfil dos pacientes internados e seus familiares e revelar os efeitos da internação em UTI no cotidiano das famílias. Os familiares expressaram diversos sentimentos como, tristeza, angústia, desespero, medo e dor, e os relacionava as incertezas do processo hospitalização e a possibilidade de perda do seu ente querido. Além de considerarem a situação de ter um membro em desvio de saúde numa UTI como uma experiência dolorosa e de grande sofrimento. Assim, conhecer a percepção dos familiares que enfrentam situação de hospitalização de um dos seus membros em UTI permitiu a identificação dos efeitos da internação sobre a família, constituindo um importante passo para a reflexão da necessidade de uma elaboração de um plano de assistência à família, considerando as necessidades e expectativas do binômio paciente-família.

    Full Text Available La idea de selección interna, propuesta originalmente por Lancelot Whyte, no sólo sirve para entender el papel causal que los constreñimientos del desarrollo tienen en evolución; sino que además puede hacernos comprender de qué modo esos factores organísmicos o internos, cuya importancia la Biología Evolucionaria del Desarrollo hoy quiere rescatar, son pasibles de ser considerados desde una perspectiva variacional o seleccional compatible, pero no asimilable, a la Teoría de la Selección Natural. Así, considerado como un concepto autónomo y diferente al de selección natural, el concepto de selección interna puede permitirnos comprender de qué modo eso que Wallace Arthur llama developmental bias constituye una causa, efectiva y positiva, de transformaciones evolutivas irreversibles y acumulables.The idea of internal selection, originally proposed by Lancelot Whyte, not only helps to understand the causal role that the developmental constraints have in evoltion, but it can also show how these organismic or internal factors, which relevancy the Evolutionary Developmental Biology remarks today, can be considered from a variational or selectional perspective that is compatible with, but not reducible to, Natural Selection Theory. Thus, being considered as a concept autonomous and different from natural selection, the concept of internal selection can allow us to understand how that phenomenon that Wallace Arthur calls developmental bias constitutes an effective and positive cause of irreversible and cumulative evolutionary changes.

    Full Text Available FUNDAMENTO: No atendimento ao episódio sincopal é necessário estratificar o risco para melhor diferenciar pacientes que necessitam de internação hospitalar daqueles que podem ser liberados. Os critérios utilizados pelos médicos avaliadores desses pacientes em emergências cardiológicas em nosso meio são desconhecidos. OBJETIVOS: Analisar quais os critérios adotados para internação hospitalar, diferenciá-los dos utilizados nos pacientes liberados e compará-los com os preditores de alto risco definidos pelo escore de OESIL já validado para esse fim. MÉTODOS: Estudo transversal em pacientes diagnosticados com síncope na emergência em nossa instituição no ano de 2011. RESULTADOS: Dos 46.476 atendimentos realizados naquele ano, 216 foram descritos como síncope. Dos 216 pacientes analisados, 39% foram internados, sendo que as principais variáveis associadas à admissão foram síncope prévia, doença cardíaca conhecida, história negativa para acidente vascular encefálico no passado, ECG alterado e possuir plano de súde. Na comparação internação contra não internação, os escores OESIL 0-1 foram associados a maior chance de liberação hospitalar; os escores 2-3 apresentaram maior associação com internação. Um escore OESIL >2 demonstrou razão de chances 7,8 vezes maior de internação comparado com o escore 0 (p < 0,001; IC95%: 4,03-15,11. Aproximadamente 39% dos pacientes não tiveram definição etiológica e em 18% foi identificada uma causa cardiológica. CONCLUSÕES: Fatores como doença cardiovascular conhecida, história sincopal prévia, ausência de AVC prévio, possuir seguro de saúde e eletrocardiograma alterado foram os critérios utilizados pelos médicos em emergência para indicar internação hospitalar. Houve boa correlação entre os critérios clínicos e os critérios de risco do OESIL descritos na literatura.

Os resultados evidenciaram uma redução das internações e mortalidade, além de apontar maior número de internações e óbitos em indivíduos do sexo masculino. Houve menor percentual de óbitos e de pacientes internados por esquistossomose em menores de 30 anos. No entanto, a esquistossomose ainda apresenta uma importante magnitude evidenciada pelo número de óbitos por esta causa e pelo número de pacientes internados na rede hospitalar em Pernambuco. Por meio da análise espacial da distribuição da endemia no Estado, pode-se verificar que, apesar de ter ocorrido entre 1995 e 1999 uma maior dispersão das internações por esquistossomose para os municípios do Sertão e São Francisco, o número de municípios com internação hospitalar por causa da esquistossomose sofreu uma redução para Pernambuco entre 1995 e 1998, seguido de um aumento para o ano de 1999 e 2000.

  14. RI beam factory and its expected pioneering work

    1996-01-01

    The RARF (RIKEN Accelerator Research Facility) houses an intermediate-energy heavy-ion accelerator complex consisting of a K540-MeV ring cyclotron (RRC) and a couple of different types of the injectors: a variable-frequency heavy-ion linac and a K70-MeV AVF cyclotron. One of remarkable features of this facility is capability of supplying light-atomic-mass RI (radioactive isotope) beams with the world-highest level of intensities by the projectile-fragment separator, RIPS. In these several years nuclear physicists have opened up a quite new and fascinating heavy-ion science exploiting such RI beams. In order to further promote this new science, the RARF proposes 'RIKEN RI Beam Factory' as a next facility-expanding project. The factory takes the aim at providing RI beams covering over the whole atomic-mass range with the world-highest intensities in a wide energy range up to several hundreds MeV/nucleon. To realize the 'Factory' a K2500-MeV superconducting ring cyclotron will be built which boosts output energies of the RRC beams up to 400 MeV/nucleon for light ions and up to 100 MeV/nucleon for very heavy ions, preserving their beam intensities (typically 1 pμA). RI beams will be generated by the projectile fragmentation. A new type of experimental installation called 'MUSES' (Multi-USe Experimental Storage rings) will also be constructed. It consists of an accumulator-cooler ring, booster synchrotron ring and double storage rings. With MUSES, various types of unique colliding experiments will become possible: ion-ion merging or head-on collisions; collisions of either electrons or X-rays with ion (stable isotope or RI) beams; internal target experiments; and atomic and molecular physics with cooler electron beams.

    The aim of the study was to determine the chromium concentrations of soil and plant specimens taken from a rural area exposed to cement factory emissions and also to determine the blood concentrations and sensitivity conditions observed in humans residing in this rural area. The study was carried out in Cukurhisar, a town in Eskisehir-Turkey, between May 2000 an March 2001. Besides the 108 soil (36 for control) and plant specimens, which were taken from eight different directions from the cement factory, blood samples of the individuals residing in this area were taken from 258 subject (258 for control) following a physical examination, and patch tests were als applied. The chromium concentrations of the soil and plant specimens take from different places in different directions of the factory were higher than in the control areas. The physical examination of subjects did not reveal results different from those of the control group except for the diagnosis of contact dermatitis. The analyses of venous blood samples showed that chromium concentrations were found to be within the reference values given for bot groups, but higher in the subjects (P<0.001). According to the results o patch tests, sensitivity to chromium was found to be more frequent for the subject group than the control group (P<0.05). According to these results clinical tools revealed no toxic effects for the subjects, except contact dermatitis. However, sensitivity to patch tests showed that this subject group has been affected compared to the control group and that this effect increased with age

  16. Roles of factorial noise in inducing bimodal gene expression

    2015-06-01

    Some gene regulatory systems can exhibit bimodal distributions of mRNA or protein although the deterministic counterparts are monostable. This noise-induced bimodality is an interesting phenomenon and has important biological implications, but it is unclear how different sources of expression noise (each source creates so-called factorial noise that is defined as a component of the total noise) contribute separately to this stochastic bimodality. Here we consider a minimal model of gene regulation, which is monostable in the deterministic case. Although simple, this system contains factorial noise of two main kinds: promoter noise due to switching between gene states and transcriptional (or translational) noise due to synthesis and degradation of mRNA (or protein). To better trace the roles of factorial noise in inducing bimodality, we also analyze two limit models, continuous and adiabatic approximations, apart from the exact model. We show that in the case of slow gene switching, the continuous model where only promoter noise is considered can exhibit bimodality; in the case of fast switching, the adiabatic model where only transcriptional or translational noise is considered can also exhibit bimodality but the exact model cannot; and in other cases, both promoter noise and transcriptional or translational noise can cooperatively induce bimodality. Since slow gene switching and large protein copy numbers are characteristics of eukaryotic cells, whereas fast gene switching and small protein copy numbers are characteristics of prokaryotic cells, we infer that eukaryotic stochastic bimodality is induced mainly by promoter noise, whereas prokaryotic stochastic bimodality is induced primarily by transcriptional or translational noise.

  17. Sterile neutrinos beyond LSND at the neutrino factory

    2010-01-01

    We discuss the effects of one additional sterile neutrino at the Neutrino Factory. Compared to earlier analyses, which have been motivated by Liquid Scintillator Neutrino Detector (LSND) results, we do not impose any constraint on the additional mass squared splitting. This means that the additional mass eigenstate could, with small mixings, be located among the known ones, as it is suggested by the recent analysis of cosmological data. We use a self-consistent framework at the Neutrino Factory without any constraints on the new parameters. We demonstrate for a combined short and long baseline setup that near detectors can provide the expected sensitivity at the LSND-motivated Δm 41 2 -range, while some sensitivity can also be obtained in the region of the atmospheric mass splitting from the long baselines. We point out that limits on such very light sterile neutrinos may also be obtained from a reanalysis of atmospheric and solar neutrino oscillation data, as well as from supernova neutrino observations. In the second part of the analysis, we compare our sensitivity with the existing literature using additional assumptions, such as |Δm 41 2 |>>|Δm 31 2 |, leading to averaging of the fast oscillations in the far detectors. We demonstrate that while the Neutrino Factory has excellent sensitivity compared to existing studies using similar assumptions, one has to be very careful interpreting these results for a combined short and long baseline setup where oscillations could occur in the near detectors. We also test the impact of additional ν τ detectors at the short and long baselines, and we do not find a substantial improvement of the sensitivities.

    B factories present unique requirements for controls and instrumentation systems. High reliability is critical to achieving the integrated luminosity goals. The CESR-B upgrade at Cornell University will have a control system based on the architecture of the successful CESR control system, which uses a centralized database/massage routing system in a multiported memory, and VAX stations for all high-level control functions. The implementation of this architecture will address the deficiencies in the current implementation while providing the required performance and reliability. (author)

Both the measurement and the calculation were done for a different bunch length (σ) ranging from 23 to 80 ps. The PF ring impedance was estimated to be |Z/n|=3.2 Ω using the broadband impedance model. The major contribution to the impedance comes from the bellows and the gate valve sections. Improvements of these components will lower the ring impedance by half. (author)

    The utilization of an increasingly diverse range of cheap waste substrates will be an ongoing challenge for the bio-based economy, where the mobilization of nutrients from a variety of waste products will be necessary for realization of biosustainability on an industrial scale. Bioprocesses...... utilizing traditionally applied cell factories are generally based on a limited range of substrates (mainly glucose). However, a wider diversity in substrate range is highly desirable in developing biorefinery scenarios where feed-stocks containing a number of carbon sources are typically employed...

    Preparation of microcapsules with aqueous core and polyamide walls is influenced by several factors. We improved the stability of walls and size of capsules by simultaneous variation of four factors: total ratio of polymer, ratio of amines to acid chlorides, concentration of surfactant and speed of stirring. Use of factorial design minimizes the number of experiments and permits us to know the influence of these factors and of their interactions. By increasing the ratio of amines to acid chlorides and with a low concentration of total polymer, we obtained more stable capsules. Surfactant had a negative effect on the hardness of the polymer.

    The goal of the project is to observe CP violation in the bar BB system. This machine is supposed to be a factory for high energy physics, not an R ampersand D project for accelerator physics. There are a number of interrelated design issues arising from the different desires of the detector and the machine, some of which are listed in this paper. A number of background and beampipe issues are mentioned. The emphasis is on calculations. Any satisfactory design will combine measurements on existing machines with calculations pertaining to the measurement conditions as well as to the proposed machine. 57 refs

    The special tracking technique is applied for investigation of the beam-beam interaction for KEK B-factory with a crossing angle at the IP. This technique allows us to save a lot of CPU time while simulating the beam tails. The detailed comparison with the brute force tracking code has been performed in order to confirm the validity of the technique. After that, some simulation results for KEKB are presented, which have shown that, in spite of synchro-betatron resonances induced by a crossing angle at the IP, the beam halo growing is quite acceptable.

    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 Los comportamientos contraproducentes (CCP son acciones voluntarias y discrecionales que violan las normas organizacionales. Se describen los pasos seguidos para el desarrollo y validación de una escala para medirlos. A partir de la revisión bibliográfica, entrevistas focales y consultas con expertos se elaboró una escala preliminar que fue aplicada a 336 empleados argentinos. Del análisis factorial exploratorio emergió una estructura trifactorial, la que fue corroborada a través de un análisis factorial confirmatorio. La consistencia interna de los factores fue superior a .80. La validez discriminante se examinó mediante correlaciones con medidas de satisfacción, estrés laboral, percepciones de justicia, afectividad y deseabilidad social. Se discute la importancia de contar con instrumentos de medición que reflejen la cultura organizacional de las empresas latinoamericanas.

Estos dos factores corresponden a la subescala visual y a la subescala cinestésica. La consistencia del test fue satisfactoria, tanto la consistencia de la puntuación total del test, como la de cada una de las dos subescalas. El MIQ-R correlacionó -.34 con el Cuestionario de Viveza de Imagen del Movimiento (VMIQ, y -.26 con el Cuestionario de Viveza de Imagen Visual (VVIQ. La versión española del MIQ-R se considera una buena medida de imagen del movimiento.

  12. A low energy neutrino factory with non-magnetic detectors

    Huber, Patrick

    2008-01-01

    We show that a very precise neutrino/anti-neutrino event separation is not mandatory to cover the physics program of a low energy neutrino factory and thus non-magnetized detectors like water Cerenkov or liquid Argon detectors can be used. We point out, that oscillation itself strongly enhances the signal to noise ratio of a wrong sign muon search, provided there is sufficiently accurate neutrino energy reconstruction. Further, we argue that apart from a magnetic field, other means to distinguish neutrino from anti-neutrino events (at least statistically) can be explored. Combined with the fact that non-magnetic detectors potentially can be made very big, we show that modest neutrino/anti-neutrino separations at the level of 50% to 90% are sufficient to obtain good sensitivity to CP violation and the neutrino mass hierarchy for $\\sin^22\\theta_{13}>10^{-3}$. These non-magnetized detectors have a rich physics program outside the context of a neutrino factory, including topics like supernova neutrinos and proton...

    As production target for Neutrino Factories,free mercury jets with high axial velocity of about 20 m /s are being studied.For the CERN-Neutrino- Factory proposal with a 4 MW beam power,but with a relatively large beam size at 2 .2 GeV /c and pulsed at 50 Hz ,maximum energy deposition densities of below 20 J /g and average power densities of about 1 kW /g are expected in the target.Therefore a study has been made which discusses the feasibility and limits of a stationary target.It is proposed to use densely packed solid spheres of heavy material and with diameters in the millimeter range.These spheres are con fined inside a Titanium container and cooled by an e fficient water circuit or possibly by He-gas.Dynamic response,as pressure pulses and vibrations are greatly reduced in the small target granules due to relatively long beam bursts,each with a duration of 3.3 s .The encouraging results achieved in this assessment justify to pursue further experimental tests,in particular of the cooling...

  14. Recent developments on the TRIUMF KAON factory proposal

    1988-06-01

    The TRIUMF KAON Factory proposal has made considerable progress on both technical and political fronts over the last year. A racetrack-shaped lattice is now being considered in conjunction with a three-element slow extraction system in an effort to reduce losses to the 0.1% level. 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. The H - extraction system for the cyclotron has been tested successfully with 66 μA pulsed and 10 μA average beams. On the political side, British Columbia has agreed to fund the buildings and tunnels (Cdn dollar 87M) and is making the KAON Factory its top 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. Approval of dollar 11 million in pre-construction R and D funds is expected imminently, permitting formal negotiations to start abroad, with final approval for construction coming in 1989

  15. Review of coherent effects in B- and Φ-factories

    Heifets, S.

    1998-01-01

    The author reviews instabilities which may be relevant to the storage rings under construction and in commissioning such as Φ-factor in Frascati, and the B-factories at SLAC and KEK. For this reason, he doesn't consider effects specific mostly for proton machines. Beam-beam effects are also not included because today these effects look like a somewhat distant future for the Φ- and B-factories, assumption that may become wrong very quickly. Personal interest and limited knowledge of the author also defined selected topics. It has been known for more than 30 years that interaction of the beam with environment can cause beam instabilities. Until recently, impedances and wake fields were associated with resistivity and variations of the beam pipe geometry. In addition, interaction with other (foreign) particles, existing or produced by the beam such as ions, trapped- or photo-electrons, may become important for multi-bunch beams, causing instabilities with growth rates substantially higher than these caused by geometric wake fields. The main topics are: Impedances; Traditional instabilities -- single- and multi-bunch instabilities; Effect of ions; and New instabilities

    2015-03-13

    In order to model the effect of mixture parameters and material properties on the hardened properties of, prestressed self-compacting concrete (SCC), and also to investigate the extensions of the statistical models, a factorial design was employed to identify the relative significance of these primary parameters and their interactions in terms of the mechanical and visco-elastic properties of SCC. In addition to the 16 fractional factorial mixtures evaluated in the modeled region of -1 to +1, eight axial mixtures were prepared at extreme values of -2 and +2 with the other variables maintained at the central points. Four replicate central mixtures were also evaluated. The effects of five mixture parameters, including binder type, binder content, dosage of viscosity-modifying admixture (VMA), water-cementitious material ratio (w/cm), and sand-to-total aggregate ratio (S/A) on compressive strength, modulus of elasticity, as well as autogenous and drying shrinkage are discussed. The applications of the models to better understand trade-offs between mixture parameters and carry out comparisons among various responses are also highlighted. A logical design approach would be to use the existing model to predict the optimal design, and then run selected tests to quantify the influence of the new binder on the model.

    A urano-thorianite mineral from Madagascar is industrially treated at the factory of the Bouchet in order to obtain pure thorium in the form of the nitrate and a uranium concentrate in the form of uranate. The required factory was designed and constructed in 1955 and 1956 by the firm Potasse et Engrais Chimiques (P.E.C.) on behalf of the French Atomic Energy authority. The mineral which has previously undergone a gravimetric sorting and enrichment at the mine, is in the form of a heavy rock (the density can be as high as 10), having a cubic structure. It consists principally of a mixture of thorium oxide and uranium oxide and contains between 50 and 75 per cent thorium and between 5 and 20 per cent of uranium. On the same sample a high content in either thorium or uranium in general corresponds to a low content in the other of the two metals; this rule is not however always obeyed absolutely. Among other elements present we shall only mention the Pb, Fe, Ce, Ra and other radioactive elements, since their presence influences the treatment of the mineral. We shall first briefly describe the process, which has already been described in previous publications, we consider to be worthy of attention. (author) [fr

    To assess the prevalence of musculoskeletal symptoms and their association with sociodemographic risk factors among female garment factory workers in Sri Lanka. 1058 randomly selected female garment factory workers employed in the free trade zone of Kogalla, Sri Lanka were recruited to complete two interviewer-administered questionnaires assessing musculoskeletal symptoms and health behaviors. Musculoskeletal complaints among female garment workers in the FTZ of Kogalla are less common than expected. Sociocultural factors may have resulted in underreporting and similarly contribute to the low rates of healthcare utilization by these women. 164 (15.5%) of workers reported musculoskeletal symptoms occurring more than 3 times or lasting a week or more during the previous 12-month period. Back (57.3%) and knee (31.7%) were the most common sites of pain. Although most symptomatic women reported that their problems interfered with work and leisure activities, very few missed work as a result of their pain. Prevalence correlated positively with increased age and industry tenure of less than 12 months. Job type, body mass index, and education were not significant predictors of musculoskeletal symptoms.

  19. The intense neutron generator and future factory type ion accelerators

    International Nuclear Information System (INIS)

    Lewis, W.B.

    1968-01-01

    A neutron factory is likely to sell its product in the form of isotopes. To ay neutron factories are nuclear reactors. Ion accelerators may also produce isotopes by direct interaction and, at high enough energies, mesons and hyperons. The challenge of the electrical production of neutrons goes far beyond the isotope market. It challenges the two popular concepts for long term large scale energy, the fast breeder reactor and controlled thermonuclear fusion. For this use about 4% of nuclear generated power would be applied in a feedback loop generating extra neutrons. Competition rests on operating and processing costs. The Intense Neutron Generator proposal now cancelled would have been full scale for such a use, but much further advance in accelerator engineering is required and anticipated. Perhaps most promising is the application of the ion drag principle in which rings of fast electrons are accelerated along their axis dragging ions with them by electrostatic attraction. Due to the much larger mass of the ions they can acquire much higher energy than the electrons and the process could be efficient. Such accelerators have not yet been made but experimental and theoretical studies are promising. (author)

    The Neutrino Factory and Muon Collider Collaboration (MC) comprises about 140 U.S. and non-U.S. accelerator and particle physicists. The MC is carrying out an R and D program aimed at validating the critical design concepts required for the construction of such machines. We are committed to encouraging international cooperation and coordination of the R and D effort. Main activities of the MC include a Targetry program, a MUCOOL program, a component development program, and a theory and simulation effort. Moreover, the MC has participated in several feasibility studies for a complete Neutrino Factory facility, with the aim of identifying any additional R and D activities needed to prepare a Zeroth-order Design Report (ZDR) in about two years and a Conceptual Design report (CDR) about two years thereafter. In this paper, the R and D goals in each area will be indicated, and the present status and future plans of the R and D program will be described
