    Franciele Cascaes da Silva

    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.

    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. This paper presents the conceptual design of the neutrino factory accelerator facility developed by the European Commission Framework Programme 7 EURO$\

    2002-01-01

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

    1979-01-01

    Technological improvements in accelerator design in the 1960's resulted in the capability to develop medium-energy proton accelerators with beam intensities of almost 1 mA. These beams are able to produce fluxes of secondary particles, including pions, muons, neutrinos, and neutrons, which are as much as 10,000 times as intense as those previously available. Those machines built for optimum meson production are commonly called meson factories. The characteristics of these facilities are reviewed, and the present programs in applied research, and some potential areas of future work are discussed

    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

    1989-09-01

    Proposals for high intensity proton synchrotrons (typically providing 100 μA (6 x 10 14 p/s)) at 30 GeV have been made in Canada, Europe, Japan, the USA and the USSR. These beams would be roughly 100 times more intense than those available now and would yield equivalent increases in the fluxes of secondary particles (kaons, pions, muons, antiprotons, hyperons and neutrinos) - or cleaner beams for a smaller increase in flux. The ability to investigate rare processes on the precision frontier opens new avenues to fundamental questions in both particle and nuclear physics, complementary to traditional approaches via the energy frontier. The demand for higher currents has led to novel features in many of the accelerator designs: asymmetric magnet cycles, avoidance of transition crossing, separate collector and stretcher rings, three-dimensional beam painting at injection, bucket-to-bucket beam transfer, perpendicular biassing of microwave ferrite in the rf tuners, the use of Siberian Snakes to preserve polarization, and the addition of a pre-septum to make slow extraction >99.8% efficient. Other characteristic features include rapid cycling rates, booster stages, H - injection, low impedance enclosures, powerful feedback systems for control of beam instabilities and beam loading, and local collimation systems for handling beam loss. This paper reviews the general features of kaon factory accelerator design and the status of the various proposals

    Full Text Available La escala de bienestar psicológico surge a partir del modelo multidimensional propuesto por Ryff (1989. 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.

    Full Text Available Through interesterification of oils and fats is possible to obtain structured lipids (SL, which are considered functional foods, due their potential effects on the prevention of diseases. For this reason, there is great interest in the production of SL. The objective of this paper was to obtain structured lipids from chemical interesterification from palm kernel fat and fish oil and to analyse the interactions that occur in the binary mixtures of these lipids. Six samples consisting of two individual samples and four binary mixtures were studied. The samples were analyzed for fatty acid composition and consistency at the range temperature from 5 to 25ºC. A mathematical model of multiple regression of the quadratic type was applied. The results showed that the interactions between the two components were significant. The consistency depended on the palm kernel fat and on the binary interactions between palm kernel fat and fish oil. The negative coefficients to the consistency showed an antagonic effect which is characteristic of eutectic interactions between fats.Por medio de la interesterificación de mezclas de aceites y grasas, es posible obtener lípidos estructurados (SL, los cuales son considerados como alimentos funcionales por presentar gran potencial en la prevención de diversas enfermedades.

    The Japan Atomic Energy Research Institute, JAERI, has started, drafting a construction plan for the 'Positron Factory', in which intense energy-controllable monoenergetic positron beams are produced from pair-production reactions caused by high-energy electrons from a linac. The JAERI organized a planning committee to provide a basic picture for the Positron Factory. This article presents an overview of the interactions of positrons, intense positron sources and the research program and facilities planned for the project. The interactions of positrons and intense positron sources are discussed focusing on major characteristics of positrons in different energy ranges. The research program for the Positron Factory is then outlined, focusing on advanced positron annihilation techniques, positron spectroscopy (diffraction, scattering, channeling, microscopy), basic positron physics (exotic particle science), and positron beam technology. Discussion is also made of facilities required for the Positron Factory. (N.K.)

    In addition to hearing the latest experimental and theoretical developments at the 17th International Symposium on Lepton Photon Interactions in Beijing, delegates were brought up-to-date on the substantial progress towards the realization of a Tau-Charm Factory in the Chinese capital. Opening the Symposium, Zhou Guangzhao, President of the Chinese Academy of Sciences, expressed a commitment of the Chinese government to basic research and its interest in the continuing development high energy physics in China. Following the very successful construction and operation of Beijing's Electron-Positron Collider, BEPC, the Chinese government has provided 5M yuan ($US 600,000) for a feasibility study by the end of 1996 for a Tau-Charm Factory at Beijing's Institute of High Energy Physics (IHEP). Professor Zhou expressed his belief that, once approved, such a factory would greatly enhance high energy physics in China.

    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

    Rhizocephalan parasites have a peculiar life cycle, and their adults lost almost all traits found usually in Crustacea. Despite some data on anatomy and ultrastructure of interna of Peltogastridae, some crucial aspects of morphology are still unknown. For example, there is only one mentioning of myocytes found in interna of Rhizocephalans (Sacculina carcini). So we aimed at studying the muscular system of the interna of Peltogaster paguri using serial histological sectioning and fluorescent staining (TRITC-labeled phalloidin) with confocal microscopy. Within the wall of the main trunk we found striated muscular fibers. The majority of these fibers form a unidirectional single spiral. There are additional small fibers that connect the coils of the large spiral. The density of muscular fibers is highest near the externa stalk, and the number of muscle fibers decreases towards the distal part of the main trunk. We suggest that such a muscular system could provide peristaltic movements of the main trunk and the transport of nutrients through the interna. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The past 15 years have seen an increasing governmental and corporate concern for the environment worldwide. For governments, information about the environmental performance of the industrial sector is required to inform macro-level decisions about environmental targets such as those required to meet UN directives. However, in many African, Asian, and Latin American countries, researching and reporting company environmental performance is limited. This article serves as a contribution to filling the gap by presenting evidence of physical and chemical risk in Nigerian factories. One hundred and three factories with a total of 5,021 workers were studied. One hundred and twenty physical and chemical hazards were identified and the result shows a high number of workers exposed to such hazards. The study also reveals that workers' awareness level of chemical hazards was high. Yet the danger was perceived in behavioral terms, especially by manufacturing firms, which tend to see environmental investment in an increasingly global economy as detrimental to profitability.

    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.

B-mesons have revealed unexpected and important quark physics. Well-known examples are the long lifetime of the B-mesons, indicating a large gap between the third and second quark generation (compared to that between the second and the first), and relatively large mixing of the neutral B-meson and its antiparticle, now interpreted as being due to a heavy sixth ('top') quark

    After more than three years of intensive evaluation, the Japanese government has approved the conversion of the TRISTAN electronpositron collider at the national KEK Laboratory to a two-ring asymmetric B-meson factory. The project will take about five years to complete. Initial construction will proceed while TRISTAN experiments continue datataking, expected to continue until summer 1995. When it becomes operational in 1998, the new facility (TRISTAN II) will be capable of producing more than ten million B meson pairs each year. Detailed studies of their decay properties are expected to reveal answers to the long-standing puzzle of the violation of CP symmetry - combined left-right reversal and particle-antiparticle substitution

  3. SRF for neutrino factories

    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)

    We have started drafting a construction program for the Positron Factory, in which linac-based intense monoenergetic positron beams are planned to be applied for materials science, biotechnology and basic physics and chemistry. A technical survey study confirmed the feasibility of manufacturing a dedicated electron linac of 100 kW class with a beam energy of 100 MeV, which will produce a world-highest monoenergetic positron beam of more than 10{sup 10}/sec in intensity. A self-driven rotating converter (electrons to positrons and photons) suitable for the high power electron beam was devised and successfully tested. The practicability of simultaneous extraction of multi-channel monoenergetic positron beams with multiple moderator assemblies, which had been originated on the basis of a Monte Carlo simulation, was demonstrated by an experiment using an electron linac. An efficient moderator structure, which is composed of honeycomb-like assembled moderator foils and reflectors, is also proposed. (author)

    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 particle and nuclear physics experiments. 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 components to be built and evaluated -fast-cycling dipole and quadrupole magnets, a dual-frequency magnet power supply, ceramic beam pipes with internal RF shields, an RF cavity (using perpendicular bias), an extraction kicker, and RF beam chopper, and production targets. Environmental, industrial and economic impact studies have also been completed and the cost estimates and schedule updated. The total cost of $708 million (Canadian) will be shared equally between Canada, British Columbia (already approved) and international contributors. The federal decision is expected shortly.

    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

In pigs, the anatomical-pathological and microbiological findings have been described. In this report, we describe radiographic findings in affected pigs. A total of 25 pigs with a head tilt and circling, as clinical signs of otitis media and interna, were examined. The majority were weaner-pigs with dyspnea or rhinitis. In radiographs, there was an increased opacity of the bulla tympanica, often accompanied by marginal destruction or thickening of the bulla wall. The radiographic findings confirmed the clinical diagnosis in each affected pig, but there were 5 false positive interpretations

    Full Text Available El Inventario de Depresión Estado-Rasgo (IDER evalúa de forma breve distintos síntomas depresivos. El objetivo es evaluar algunas propiedades psicométricas del IDER en Perú. La muestra estuvo formada por 314 estudiantes entre 11 y 18 años de secundaria en un colegio limeño. Los resultados indican una estructura bidimensional –que corresponde con la delimitación conceptual del inventario original–. Sin embargo, algunos ítems presentaron cargas comparativamente bajas, probablemente debido a variaciones culturales. Adicionalmente, la consistencia interna para la dimensión de Estado y Rasgo presentó valores alfa de Cronbach de 0.76 y 0.68, respectivamente. El cuestionario IDER satisface el criterio de invariabilidad de la estructura interna y puede dar una alternativa favorable para el diagnóstico y evaluación de la depresión en adolescentes peruanos.

  16. AutoPyFactory: A Scalable Flexible Pilot Factory Implementation

    International Nuclear Information System (INIS)

    Caballero, J; Hover, J; Love, P; Stewart, G A

    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.

    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.

    sufficient titers. To improve the production of polyketides biological engineering principles have been applied for the development and engineering of microbial polyketide cell factories. The two biological hosts used for heterologous polyketide production were Aspergillus nidulans and Saccharomyces...... phosphopantetheinylase (PPTase). This versatile vector system can easily be used for expression of other polyketides of interest as well as extended to express whole gene clusters. After achieving proof of principle in terms of expression, the polyketide cell factory must be optimized. The optimization can be achieved...... characterization in bioreactors revealed that the yields of 6-MSA on biomass increased albeit not significantly. As a result of this it may be argued that there is still more work to be done in terms of model building in A. nidulans.

    Full Text Available Desde hace algunos años se han realizado intentos para elaborar mapas globales utilizando diferentes tipos de imágenes, métodos y sistemas de nomenclatura. 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 %. Solo 2 % de los pixeles coinciden en 4 mapas (principalmente ciudades y agua y 88 % coinciden en 2 ó 3 mapas. El principal problema es la distinción entre las áreas de cultivo y otro tipo de vegetación. Los mapas más recientes, basados en la nomenclatura propuesta por la FAO, muestran mayor exactitud pero aún no la suficiente para considerarlos como adecuados para detectar los principales tipos de cubierta terrestre. El uso de mapas globales de cobertura terrestre debe ser adecuadamente contextualizado en situaciones de gran diversidad.

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.

    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)

    There are two principles which the management of a research institute like KEK must respect when dealing with such big project as B-Factory. One is the scientific merit of the project and the other is the organizational consideration which includes financial, human, technical and historical elements. Ideally, the two principles are to be fully taken into account. But, in many cases, one or the other is only partially fulfilled due to unavoidable circumstances. The lack of flexibility to respond to all possible situations is more dangerous and may lead to a disaster as in the case of SSC. I will describe the process which lead to the successful construction, operation and physics presentations of KEK B-Factory following faithfully the official records.

I will describe the process which lead to the successful construction, operation and physics presentations of KEK B-Factory following faithfully the official records. (author)

    The Apiary B Factory is a proposed high-intensity electron-positron collider. This paper will present the lattice design for this facility, which envisions two rings with unequal energies in the PEP tunnel. The design has many interesting optical and geometrical features due to the needs to conform to the existing tunnel, and to achieve the necessary emittances, damping times and vacuum. Existing hardware is used to a maximum extent. 8 figs. 1 tab

    The design study for the TRIUMF Kaon Factory has recently been funded. A short discussion of the scientific motivation is given first, followed by a brief description of the 30 GeV synchrotron which is being proposed. There will be five rings altogether using the present TRIUMF 500 MeV cyclotron as an injector. If the project is funded in 1990 the accelerators would be completed in 1995 or so, and the experimental programme would start a year later

    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

    The Photon Factory has grown at a considerable rate, and 600 experiments are carried out in 1991, while the number of users is now 2300 including about 500 from industrial sectors. The use of synchrotron radiation increased from fundamental research to industrial development. The development at the Photon Factory is supported by the capability of the accelerators. At present, the 2.5 GeV PF ring is operated with positrons at the initial beam current of 350 mA. The total operation time was 3500 hours in the fiscal year 1990. The development of an avalanche mode photodiode, the observation of quantum beat in the experiment of nuclear Bragg scattering, the measurement of photo-electron and photo-ion spectroscopy were carried out. The conversion of TRISTAN main ring to an ultrahigh brilliance and high coherence source is planned for the future. The annual PF Symposium was held, and Professor H. Winick gave the lecture 'Ultrahigh brightness and coherent radiation from large storage rings'. In this report, the outline of the Photon Factory and the activities in Divisions of Injector Linac, Light Source and Instrumentation are described. (K.I.)

  13. 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

    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.

    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.)

    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.

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

    Directory of Open Access Journals (Sweden)

    Nicholas Hatzirodos

    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.

    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.)

    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.

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

  13. A Tau-Charm Factory at CEBAF

    Energy Technology Data Exchange (ETDEWEB)

    1994-04-01

    It is proposed that a Tau Charm Factory represents a natural extension of CEBAF into higher energy domains. The exciting nature of the physics of charm quarks and tau leptons is briefly reviewed and it is suggested that the concept of a linac-ring collider as a Tau Charm Factory at CEBAF should be seriously studied.

  14. Photon Factory activity report, 1989

    International Nuclear Information System (INIS)

    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).

  16. The KAON Factory at TRIUMF

    International Nuclear Information System (INIS)

    Craddock, M.K.

    1992-08-01

    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 particle and nuclear physics experiments. 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 components to be built and evaluated -fast-cycling dipole and quadrupole magnets, a dual-frequency magnet power supply, ceramic beam pipes with internal rf shields, and rf cavity (using perpendicular bias), an extraction kicker, and rf beam chopper, and production targets. Environmental, industrial and economic impact studies have also been completed and the cost estimates and schedule updated. The total cost of $708 million (Canadian) will be shared equally between Canada, British Columbia and international contributors: the first two-thirds of this sum have already been approved and negotiations for the remainder are under way. 25 refs., 7 figs

    At a ceremony marking the start of construction, members of the US Congress and Secretary of Energy Hazel O'Leary hailed the new Asymmetric B Factory as the key to continued vitality of the Stanford Linear Accelerator Center (SLAC). Being built in collaboration with the Lawrence Berkeley Laboratory and the Lawrence Livermore National Laboratory, the B factory is a $177 million upgrade of the existing PEP electron-positron collider. Scheduled for completion in 1998, the B factory will generate many millions of B mesons, allowing, among other physics, an intensive search for the phenomena of CP violation in the decays of these particles.

  2. Factorial correlators: angular scaling within QCD jets

    International Nuclear Information System (INIS)

    Peschanski, R.

    2001-01-01

    Factorial correlators measure the amount of dynamical correlation in the multiplicity between two separated phase-space windows. We present the analytical derivation of factorial correlators for a QCD jet described at the double logarithmic (DL) accuracy. We obtain a new angular scaling property for properly normalized correlators between two solid-angle cells or two rings around the jet axis. Normalized QCD factorial correlators scale with the angular distance and are independent of the window size. Scaling violations are expected beyond the DL approximation, in particular from the subject structure. Experimental tests are feasible, and thus would be welcome. (orig.)

    2017-01-01

    As a reaction to current challenges in factory planning, many companies think about introducing factory standards to lower planning times and decrease planning costs. If these factory standards are set-up with a high level of modularity, they are defined as modular factory systems. This paper deals with the main current problems in the application of modular factory systems in practice and presents a solution approach with its basic models. The methodology is based on methods from factory pla...

  4. The factory as a battlefield

    Directory of Open Access Journals (Sweden)

    Helena Chávez Mac Gregor

    Full Text Available The crisis of labour is also one of representation. Some contemporary artists working with moving images have been questioning how to represent capital, labour and the worker. Isaac Julien or Harun Farocki, for example, have focused on interlacing characters - from fiction or reality - with geopolitical spaces in order to present the entanglement of the economical new order with the new forms of labour. The South African artist Simon Gush has shifted from this trend in order to present labour without directly representing the workers. In his artwork there is no longer a search for the political subject as a historical force or for the individuals who occupied its place; instead he leads viewers to a critical reading of an object, allowing a staging of the past from the viewpoint of the present. That is what I think Red does. In this article I explore Gush's connections with Marx, Benjamin and Steyerl to show how Gush's work is part of a critical tradition that has abandoned the subject as the privileged instance of political agency; turning the emphasis of the modern schema upside down, it focuses on the object as the force of emancipation. I would like to suggest that Gush used an object, Mandela's red Mercedes-Benz, to produce another image so that the story told is not necessarily that of a symbol of pacification, but one in which the factory was a battlefield. In this way I explore the emancipatory potencies of the object. What I propose is a reading of Red from the point of view of a return to the thing, where the latter becomes a political force.

  9. As diferenças entre comunicação interna e endomarketing

    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.

  10. Rationes implícitas y sensaciones internas en las Meditationes de Prima Philosophia

    Directory of Open Access Journals (Sweden)

    Mauricio Otaíza

    2014-01-01

    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.

  11. Corte y sellado reversible de dientes para obtener superficies internas de esmalte incólumes

    Directory of Open Access Journals (Sweden)

    Full Text Available Las superficies internas de los dientes, que se obtienen por cortes con discos, están generalmente desorganizadas por los giros, la velocidad y la rugosidad del disco. El calor altera la superficie y el agua de la refrigeración la composición química porque disuelve los componentes. En estudios de difusión, el perfil se borra por el corte, lo que anula resultados. Objetivo: desarrollar un método de sellado de superficies internas, ya cortadas antes de los ensayos de difusión, sin dejar trazas químicas o partículas. Materiales y metedos: se probó in vitro la habilidad de cuatro materiales de sellado con 40 especimenes, provenientes de 20 coronas de terceros molares, cortadas sagitalmente. Los especímenes se distribuyeron aleatoriamente en cuatro grupos (n = 10: G1: Teflón (Topex®, G2: Tela de caucho (Dental DAM®, G3: película de cloruro de polivinilo (Vinilpel® y G4: Cinta aislante (Tesa®. Se usó una solución de azul de metileno (AM al 2% por 6 días como indicadora de filtración. Por observación visual de cada muestra, se le asignó un valor (sí o no dependiendo de la presencia o ausencia de cualquier punto MB sobre la superficie de sellado. Los resultados fueron analizados siguiendo un modelo estadístico de respuesta binomial. Resultados: Siguiendo los procedimientos descritos, el teflón es el único material que previene la filtración de AM en la superficie interna expuesta por el corte. Conclusión: Se propone un protocolo de sellado reversible de las superficies internas con teflón, previo al corte de los dientes, para no alterar los resultados experimentales.

    Full Text Available Medical therapies in patients with Meige syndrome, including botulinum toxin injection, have been limited because of incomplete response or adverse side effects. We evaluated a patient with Meige syndrome who was successfully treated with deep brain stimulation (DBS in the globus pallidus interna (GPi. This case report and other previous reports suggest that bilateral GPi DBS may be an effective treatment for medically refractory Meige syndrome, without significant adverse effects.

    Full Text Available Resumen Este artículo es síntesis de una investigación ya terminada, orientada por la pregunta: ¿Qué lugar tiene la consistencia imaginaria en el nudo borromeo? Fueron tomados como referentes principales Sigmund Freud y Jacques Lacan. Para su desarrollo se revisaron planteamientos acerca de la libido, la pulsión y otros más elementos de lo imaginario, tales como las experiencias ópticas y el nudo borromeo. Este último, figura topológica que ilustra la manera en que se articulan los registros, pero además, muestra que se tejen entre ellos en función de un elemento central que tiene una faz imaginaria y también tiene la consistencia que puede tener un concepto, este elemento es el objeto a. Palabras clave: Nudo borromeo, consistencia, imaginario, topología. Abstract This article summarizes an investigation led by the question: which is the place of the imaginary consistency in the Borromean knot? The main references of the investigation were Sigmund Freud and Jacques Lacan. For the development of this, there were revised different approaches to libido, drive, and other elements of the imaginary such as the optic experiences and the Borromean knot. This last one, topologic figure that illustrates how the different orders articulate, shows how they interconnect with each other around a central element which has an imaginary face and also the consistency of a concept: object a. Keywords: Borromean knot, consistency, imaginary, topology.

  18. 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.

  19. Analysis of scaled-factorial-moment data

    International Nuclear Information System (INIS)

    Seibert, D.

    1990-01-01

    We discuss the two standard constructions used in the search for intermittency, the exclusive and inclusive scaled factorial moments. We propose the use of a new scaled factorial moment that reduces to the exclusive moment in the appropriate limit and is free of undesirable multiplicity correlations that are contained in the inclusive moment. We show that there are some similarities among most of the models that have been proposed to explain factorial-moment data, and that these similarities can be used to increase the efficiency of testing these models. We begin by calculating factorial moments from a simple independent-cluster model that assumes only approximate boost invariance of the cluster rapidity distribution and an approximate relation among the moments of the cluster multiplicity distribution. We find two scaling laws that are essentially model independent. The first scaling law relates the moments to each other with a simple formula, indicating that the different factorial moments are not independent. The second scaling law relates samples with different rapidity densities. We find evidence for much larger clusters in heavy-ion data than in light-ion data, indicating possible spatial intermittency in the heavy-ion events

  20. 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.

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

  4. 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.

    Beyond doubt, the advent of a kaon factory will be of immense significance for the study of hadronic atoms. Here we will discuss some classes of experiments that certainly can and will be done at a kaon factory, as well as some very interesting possibilities which deserve investigation. Among the certains we include the observation of hadronic x rays from kaonic and μ - atoms, for both Z greater than one and for the isotopes of hydrogen, mainly for strong interaction information. More conjectural is the possibility of measuring Xi - and Ω - x rays

    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

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

    2008-01-01

    To date most studies of Neutrino Factories have focused on facilities where the energy of the muon in the storage ring has been in the range of 25-50 GeV. In this paper we present a concept for a Low-Energy (∼ 4 GeV) neutrino factory. For baselines of O(1000 km), the rich oscillation pattern at low neutrino interaction energy (0.5 - ∼3 GeV) provides the unique performance of this facility with regard to its sensitivity to CP violation and the determination of the neutrino mass hierarchy. A unique neutrino detector is needed, however, in order to exploit this oscillation pattern. We will describe the basic accelerator facility, demonstrate the methodology of the analysis and give an estimate on how well the Low-Energy neutrino factory can measure θ 13 , CP violation and the mass hierarchy. We will also describe the detector concept that is used, show a preliminary analysis regarding its performance and indicate what R and D is still needed. Finally we will show how the Low-Energy neutrino factory could be a step towards an energy frontier muon collider.

    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.

    The heightening of productivity in the factories manufacturing heavy electric equipment has been advanced so far by the rationalization of direct workings such as NC, robots and the adoption of FMS (flexible manufacturing system). However, as CAD advances, the effective utilization of these data and the expansion to future CIM (computer integrated manufacture) have become to be demanded. In the Hitachi Works of Hitachi Ltd., it was decided to advance the synthetic rationalization by adopting FA (factory automation) system. Steam turbine blades, pipings for nuclear power plants and motor coils were taken up as the objects since these are important parts, and for the purpose of the drastic heightening of QA level, the heightening of accuracy and the shortening of processes, the synchronization with field installation schedule and the creation of safe working place environment, the FA projects for these three sections were simultaneously planned. When the automation of non-mass production factories is promoted, there are the unmanned factories combining FMS lines for relatively many products and those characterized by FMC of shortening preparation time for small lot products, and this is the examples of the former. The system constitution for FA and the production management combined with it are described. The high reliability of the optical network was regarded as important. (Kako, I.)

For this purpose, some experiences were adopted - Factory of Barren Ores tailing use for filling up the open pit where water with uranium content 3-5 mg/l is located. Factory of Barren Ores waste are passed through heap leaching and have some amount of uranium salts dissolved in water. Thus, we propose to dissolve uranium from Factory of Barren Ores wastes with uranium bearing water flowing out from gallery and filling up the open-pit by radioactive wastes. In so doing, uranium content flowing out from gallery will increase twice, and further, passing them through apricot's shell, as a sorbent, we will clean the water against radionuclides. Residue samples with uranium content 0,015% from Factory of Barren Ores and uranium bearing waters from gallery 1 with uranium content 0,0025 g/l were used for laboratory tests. After which, a slurry was prepared by means of residue mixing with water in ratio of solid and liquid phases (S:L) - 1:2 and 9,7 ml of sulfuric acid (Ρ=1,82) was added which corresponds consumption by H 2 SO 4 176,54 kg/t. For the first test, leaching was carried out during 4 hours at ph=1,6 at room temperature. For the second test, leaching was carried out at 60 d eg C a nd ph=1,6 during 4 hours. Slurry heating and mixing was carried out by means of magnetic mixer. The basic residue leaching indicators are provided in this article.

Para ello, se toma como estudio de caso las migraciones que desde mediados de la década de 1990 se realizan desde el Istmo veracruzano hacia la frontera norte de México y los campos de agricultura intensiva de Sinaloa. Se muestra que, a través de la migración laboral de trabajadores nahuas y popolucas de la Sierra de Santa Marta, regiones antes inconexas se articulan actualmente de manera desigual.

    Full Text Available Este artículo tiene como objetivo evaluar, en términos de su consistencia cardinal, ordinal y dicotómica, cinco indicadores alternativos de especialización comercial. Tres están basados en el enfoque de las ventajas comparativas reveladas: una versión simétrica del índice de Balassa, el chi-cuadrado y el índice de Ventajas Relativas del Comercio. Los otros dos están basados en el enfoque de la balanza comercial: una variante del índice de Michaely y otra del índice de Iapadre. Se aplica al caso particular del comercio mundial de mantequilla de Argentina y Uruguay en el período 1995-2006. Los resultados varían entre los dos países, habiéndose encontrado que algunos indicadores podrían utilizarse de manera sustitutiva mientras que otros deberían utilizarse de manera complementaria. En términos económicos, se detecta una especialización fluctuante según los años en Argentina y mucha estabilidad en Uruguay. // This study aims to evaluate, in terms of their cardinal, ordinal, and dichotomy consistency, five alternative comercial specialization indicators: a Balassa symmetric index version; a Chi-Squared Index; and the Relative Trade Advantage Index, all these three based on revealed comparative advantage theory; and two additional: Michaely Index variation, and Iapadre Index variation, based on trade balance flows. It is applied to the particular case of Argentina and Uruguay butter world trade during 1995-2006. The results vary for both countries. Some indicators are found to be useful as substitutes while other in a complementary manner. Economically, the indicators show that the Argentine specialization fluctuates among years while the Uruguayan is very stable.

  15. Especificación formal en OCL de reglas de consistencia entre los diagramas de clases y casos de uso de UML y el modelo de interfaces Formal OCL specification of consistency rules between the UML class and the use case models and the interfaces model

    2008-01-01

    Full Text Available En el ciclo de vida del software, durante las fases de definición y análisis, se realiza una especificación de los requisitos. Para ello, es necesario realizar un proceso de captura de las necesidades y expectativas de los interesados, que se traduce posteriormente en un conjunto de modelos que representan tanto el problema como su solución. Por lo general, la mayoría de esos modelos se expresan en el lenguaje de modelado unificado -UML-, que define un conjunto de artefactos que permiten especificar los requisitos del software, los cuales deberían guardar consistencia, cuando se trate del mismo modelo. Sin embargo, la consistencia entre diferentes artefactos no se encuentra definida en la especificación de UML y poco se ha trabajado con este tipo de consistencia. En este artículo se propone un método para verificar la consistencia entre el diagrama de clases y el diagrama de casos de uso de UML de una manera formal. Dicho proceso se lleva a cabo evaluando una serie de reglas definidas en el lenguaje de restricciones de objetos -OCL- que se deben cumplir para garantizar que la información brindada por dichos modelos sea consistente. Como se reconoce la participación de los dos diagramas en la elaboración de las interfaces gráficas de usuario -GUI-, se define adicionalmente la consistencia con este artefacto.In a software lifetime, during definition and analysis stages, a specification of requirements is carried out. For such a purpose, it is necessary to get through a process to capture interested persons’ needs and expectations, which will later be translated into a set of models representing both the problem and the solution. Most models are frequently expressed by the UML (Unified Modeling Language which defines a set of devices for specifying software requirements which should be consistent with the same model. However, consistency among several devices is not defined in the UML specification and not too much work has been made

    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.

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.

  4. 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.

    We discuss the issues of relevance to the design of a B factory RF system. First, the general parameter regime is outlined, and the reasons behind certain commonly made choices are indicated. This regime involves high beam currents, and many relatively short bunches. Next, the physics difficulties associated with coupled-bunch instabilities are described briefly. We then describe in general terms the alternative approaches taken by various B factory designers, the motivation for these choices, and the technical issues raised by them. Technical solutions have been proposed for both the room-temperature and the superconducting RF scenarios, and considerable R ampersand D is being carried out worldwide to confirm and optimize these solutions

    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

    Norem, J.; Repond, J.

    1994-01-01

    In this paper we explore the possibility of building a tau-charm-factory at the Argonne National Laboratory. A tau-charm-factory is an e + e - collider with a center-of-mass energy between 3.0 GeV and 5.0 GeV and a luminosity of at least 1 x 10 33 cm -2 s -1 . Once operational, the facility will produce large samples of τ pairs, charm mesons, and charmonium with either negligible or well understood backgrounds. This will lead to high precision measurements in the second generation quark and the third generation lepton sectors that cannot be done at other facilities. Basic physical properties and processes, such as the tau neutrino mass, rare tau decays, charm decay constants, rare charm meson decays, neutral D 0 -- meson mixing, and many more will be studied with unique precision. An initial design of the collider including the injector system is described. The design shows that a luminosity of at least 1 x 10 33 cm -2 s -1 can be achieved over the entire center-of-mass energy range of the factory

  1. Ultrastructural Characterization of Zika Virus Replication Factories

    2017-02-01

    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.

    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.

  4. An asymmetric B factory based on PEP

    Energy Technology Data Exchange (ETDEWEB)

    1991-02-01

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

    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.

    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.

  10. In-Factory Learning - Qualification For The Factory Of The Future

    Science.gov (United States)

    Quint, Fabian; Mura, Katharina; Gorecky, Dominic

    2015-07-01

    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.

    Luis Eusebio Alberto Avendaño González

    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.

    Los estudios sobre las migraciones se han llevado a cabo principalmente en el contexto Norte-Sur, como si se tratara de un movimiento unidireccional, cuando la realidad muestra que estos flujos se producen también en el plano horizontal, es decir, dentro de las regiones del Sur, como se puede observar en el continente africano. 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.

  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.

MÉTODOS: Estudo retrospectivo, incluindo as internações de adultos na clínica médica (n = 3.565.811 e clínica cirúrgica (n = 2.614.048 no Brasil em 2007. O Sistema de Informações Hospitalares foi utilizado como fonte de informação. A mensuração dos resultados adversos baseou-se no rastreamento de 11 condições clínicas, definidas em estudos internacionais anteriores, registradas no campo diagnóstico secundário. Foram realizadas análises bivariada e multivariada, no intuito de associar resultado adverso, óbito (variável dependente e outras variáveis como idade, utilização de unidade de terapia intensiva e realização de cirurgia. RESULTADOS: A frequência obtida foi 3,6 potenciais resultados adversos por 1.000 internações para ambas as clínicas, superior na clínica médica (5,3 por 1.000 em relação à clínica cirúrgica (1,3 por 1.000. Houve diferenças no perfil das internações: na clínica médica predominaram idosos, maior tempo médio de permanência, maior taxa de mortalidade e menor custo total de internação. O rastreador de resultado adverso mais frequente foi pneumonia hospitalar. Choque/parada cardíaca apresentou maior risco de óbito (OR = 5,76 em relação aos demais resultados adversos. Os maiores gastos com internações estiveram relacionados à sepse hospitalar. Os rastreadores de potencial resultado adverso apresentaram altas chances de óbito, mesmo com a introdução de variáveis como uso de terapia intensiva e realização de cirurgia. CONCLUSÕES: A alta frequência de resultados adversos em internações indica a necessidade de desenvolver estratégias de monitoramento e melhorias dirigidas para a segurança do paciente.

    The TRIUMF meson factory, which is based on a 6-sector isochronous cyclotron accelerating H - ions to 520 MeV, has been operating since December 1974. Two proton beams are extracted simultaneously to feed the two experimental areas. Characteristics of the beams and beam lines are given. Work is also proceeding on (i) additional beam lines, (ii) a 180 kW beam dump and thermal neutron source, (iii) a medium resolution proton spectrometer, and (iv) adding third harmonic flat-topping to the RF to permit separation of the internal orbits and reduction of the energy spread of the extracted beam to 0.1 MeV.

    Construction of the RI beam factory project in the first phase has started. The aim of the project is to provide intense radio-isotopes (RI) beams at energies of several hundred MeV/nucleon in a wide range of atomic masses. These beams will be produced by the projectile fragmentation of primary beams accelerated by a cascade of the existing ring cyclotron and a series of new ring cyclotrons. Improvements of the existing facility made for the new cyclotron complex have extended the energy range of available beams, which already opened new domains of study.

    I discuss the physics case of the standard Neutrino Factory facility coupled to an iron detector to exploit the so-called 'Golden-Channel'. The performance of the facility is impressive, although it is not free from degeneracies arising from a combination of physics and instrumental limitations. Nevertheless, one could explore at great depth the parameter of the leptonic mixing matrix as well as the mass hierarchy. Best performance is obtained with two baselines (one of them very long) and an improved magnetic detector with low energy detection threshold.

    Faced with competition Patrick Philippon - Les Defis du CEA no.179 - April 2013 from the emerging countries, the competitiveness of the industrialised nations depends on the ability of their industries to innovate. This strategy necessarily entails the reorganisation and optimisation of the production systems. This is the whole challenge for 'advanced manufacturing', which relies on the new information and communication technologies. Interactive robotics, virtual reality and non-destructive testing are all technological building blocks developed by CEA, now approved within a cross-cutting programme, to meet the needs of industry and together build the factories of tomorrow.

    1989-05-01

    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

    We investigate possible tests of CPT invariance on the level of event rates at neutrino factories. We do not assume any specific model but phenomenological differences in the neutrino-antineutrino masses and mixing angles in a Lorentz invariance preserving context, such as could be induced by physics beyond the standard model. We especially focus on the muon neutrino and antineutrino disappearance channels in order to obtain constraints on the neutrino-antineutrino mass and mixing angle differences; we found, for example, that the sensitivity |m 3 -m(bar sign) 3 |(less-or-similar sign)1.9x10 -4 eV could be achieved

    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.

    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. Radiation safety design of super KEKB factory

    2015-01-01

    The SuperKEKB factory, which was scheduled to start operation early 2015, is an electron-positron collider designed to produce an 80x10"3"4-1/cm"2/s luminosity, which is 40 times greater than the KEKB factory. Built to investigate CP violation and 'new physics' beyond the Standard Model, the facility consists of a 7-GeV electron/3.5-GeV positron linac, a 1.1- GeV positron damping ring, beam transport, and a 7-GeV electron/4-GeV positron collider. To meet this level of luminosity, the collider will be operated with a small beam size and a large crossing angle at the interaction point. According to particle tracking simulations, beam losses under these conditions will be 35 times more than those previously operated. To help optimise shielding configurations, leakage radiation and induced activity are estimated through empirical equations and detailed Monte-Carlo simulations using MARS15 code for the interaction region, beam halo collimators, emergency pathways, ducts, forward direction tunnels, and positron production target. Examples of shielding strategies are presented to reduce both leakage dose and airborne activity for several locations in the facility. (authors)

  11. 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.

    Particle identification systems are an important component of any detector at a high-luminosity, asymmetric B Factory. In particular, excellent hadron identification is required to probe CP violation in B 0 decays to CP eigenstates. The particle identification systems discussed below also provide help in separating leptons from hadrons at low momenta. We begin this chapter with a discussion of the physics motivation for providing particle identification, the inherent limitations due to interactions and decays in flight, and the requirements for hermiticity and angular coverage. A special feature of an asymmetric B Factory is the resulting asymmetry in the momentum distribution as a function of polar angle; this will also be quantified and discussed. In the next section the three primary candidates, time-of-flight (TOF), energy loss (dE/dx), and Cerenkov counters, both ring-imaging and threshold, will be briefly described and evaluated. Following this, one of the candidates, a long-drift Cerenkov ring-imaging device, is described in detail to provide a reference design. Design considerations for a fast RICH are then described. A detailed discussion of aerogel threshold counter designs and associated R ampersand D conclude the chapter. 56 refs., 64 figs., 13 tabs

    In France, the inheritance of ancient town gas factories, mainly under the responsibility of Gaz de France, has left pollutants in the soils of their sites. The aim of the national company is to control these pollutants. Several hundred of town gas factories were exploited in France from 1798 (date of the invention of the process by Lebon) to the end of the 60's. The town gas, obtained from high temperature pyrogenic decomposition of coal, led to by-products which were stored or mixed with the soil. This paper describes the environmental and quality policy carried out by Gaz de France to characterize and remove the pollutants (coke, clinker, tar, phenols, ammoniated water, hydrogen sulphide, cyanides, benzene, toluene, xylenes..) to evaluate the risks of exposure of contaminants and their possible impact on human health. A method with 17 criteria was elaborated to characterize the sites and the rehabilitation comprises three steps: the environmental audit (evaluation of the concentration of pollutants and of their possible environmental and human impact), the complementary analysis (extension of the contaminated area, nature and concentration of pollutants, geologic and hydrogeologic characterisation of the site), and the rehabilitation itself when necessary (confinement or elimination of pollutants using thermal, physico-chemical or biological treatments).

    Full Text Available This paper deals with the problem of optimizing a factory floor layout in a Slovenian furniture factory. First, the current state of the manufacturing system is analyzed by constructing a discrete event simulation (DES model that reflects the manufacturing processes. The company produces over 10,000 different products, and their manufacturing processes include approximately 30,000 subprocesses. Therefore, manually constructing a model to include every subprocess is not feasible. To overcome this problem, a method for automated model construction was developed to construct a DES model based on a selection of manufacturing orders and relevant subprocesses. The obtained simulation model provided insight into the manufacturing processes and enable easy modification of model parameters for optimizing the manufacturing processes. Finally, the optimization problem was solved: the total distance the products had to traverse between machines was minimized by devising an optimal machine layout. With the introduction of certain simplifications, the problem was best described as a quadratic assignment problem. A novel heuristic method based on force-directed graph drawing algorithms was developed. Optimizing the floor layout resulted in a significant reduction of total travel distance for the products.

    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. O tecido pericárpico da região injuriada possuía atividade da poligalacturonase similar para os tratamentos armazenados sob ar ou sob atmosfera controlada. O extravasamento de eletrólitos do pericarpo injuriado foi similar para os tratamentos sob atmosfera

De acuerdo con el artículo 139 la Constitución Política, este organismo público descentralizado del Ministerio de Justicia y Derechos Humanos tiene, como ente rector del sistema penitenciario nacional, la responsabilidad de hacer que los internos ocupen establecimientos adecuados (inciso 21 y que alcancen la reeducación, rehabilitación y reincorporación a la sociedad (inciso 22. Ambas responsabilidades, sin embargo, son claramente incumplidas. Las cárceles padecen hoy de sobrepoblación y hacinamiento sorprendentes, y es más, de condiciones adecuadas para impulsar seriamente el complejo proceso de reeducación, rehabilitación y reincorporación. Lo peor es que la sobrepoblación ya se hace incontrolable. El último año, de junio del 2011 a junio del 2012, la población de internos, según informe del INPE, llegó a 58 019, y alcanzó un asombroso crecimiento de 19,4%, es decir, 9 433 presos más. Las razones de todo este problema, sin duda, son tan diversas, que inclusive van más allá de las decisiones del propio organismo. Es conocido que esta situación es dramática en las cárceles de Lima y Callao, pero no deja de ser preocupante en el interior del país. Los autores - la mayoría - estando desempeñandonos en la Policía Nacional del Perú y siendo a la vez estudiantes de Derecho, quisimos conocer esta realidad en las cárceles en Huancayo, conformantes de la Oficina Regional Centro, y por está razón se comprometió en apoyar a las internas a través de un proceso de asesoría legal, previo estudio sobre la situación del Establecimiento Penitenciario de Mujeres de Concepción, una de la ocho cárceles de mujeres existentes en el país y la única en la zona centro.

  20. [Demodicosis of dogs--a factorial disease?].

    Science.gov (United States)

    Gothe, R

    1989-09-01

    Demodex canis is a normal resident of the intact canine skin, being present in small numbers in virtually every dog. Most animals are only carriers of the mites and do not develop clinical symptoms, therefore, demodectic mange has already to be considered as a factorial disease. The modus operandi of transition of clinically inapparent colonization of the mites into a disease may be explained according to investigations so far published multifactorially and thereby essentially as consequences of primary or secondary immunodepression. A primary immunodepression is initially based most probably on a hereditary defect of T-cells and is subsequently reinforced by substances, which are presumably synthesized and liberated not only by mites but also by secondary bacterial agents. A secondary immunodepression operates as trigger mechanism of a clinical manifestation after corticosteroid or cytostatic therapy or in course of underlying diseases of potentially immunodepressive nature, i.e., malignant neoplasia, hepatopathies, hyperadrenocorticism and lymphosarcoma.

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

    1980-01-01

    Under the NIOSH-sponsored contract, a total of 40 surveys were conducted at 28 manufacturing plants. The industries investigated were the fish, dye, leather, rubber and manufacturers and users of cutting fluids. NDELA, NMOR, NDMA and NDPhA were found in the air of several factories. In a chrome tannery, NDMA was identified at levels as high as 47 micrograms/m3 and NMOR was found at 27 micrograms/m3 in a rubber tire plant. This study has resulted in an increased understanding of man's exposure to exogenous N-nitrosamines. It is conceivable, from the information obtained in this study, that nitrosamine exposure comparable to that in the tire and rubber industry exists in other industries not yet surveyed. NIOSH is continuing its research on nitrosamines in the industrial environment. A full, industry-wide report on the 40 plant surveys is being compiled for publication.

    1989-09-01

    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. 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. For the small rings, sixfold symmetric circular lattices with high γ t are retained. In the Accumulator lattice, a straight section with double waist and controlled η function allows for H - injection and phase-space painting. The ion-optical properties of the lattices and the results from tracking studies are discussed

    Full Text Available A number of factors can influence the behavior of yeast during fermentation. Some of these factors (initial wort concentration, initial pH and percentage of corn syrup in the composition of the wort were studied in order to determine their influence on the productivity of fermentation. Fermentations were carried out at 25ºC utilizing a 2³ factorial design of these factors. The results showed that the percentage of corn syrup had no influence on process productivity, whereas initial pH and especially initial wort concentration did. It can be concluded that using pH and initial wort concentration values higher than those utilized in this work (5.5 and 20ºP, respectively will result in a higher productivity.

    The Japan Atomic Energy Research Institute, JAERI, has been promoting design studies for the 'Positron Factory', in which linac-based intense monoenergetic positron beams are planned to be applied to advanced materials characterization and new fields of basic research. A tentative goal of the beam intensity is 10 10 s -1 , which is assumed to be realized with an electron linac of 100 kW class with a beam energy around 100 to 150 MeV. We performed a technical survey on the dedicated linac. It confirmed technical feasibility of manufacturing the state-of-the-art machine. We have been carrying out a design study of the target. A new concept of the target design is proposed, which is expected to supply intense slow positron beams simultaneously for multiple beam channels, on the basis of Monte Carlo simulations. (author)

    The precision and discovery potential of a neutrino factory based on muon storage rings is studied. For three-family neutrino oscillations, we analyse how to measure or severely constraint the angle θ 13 , CP-violation, MSW effects and the sign of the atmospheric mass difference Δm 2 23 . We present a simple analytical formula for the oscillation probabilities in matter, with all neutrino mass differences non-vanishing, which clarifies the subtleties involved in disentangling the unknown parameters. The appearance of 'wrong-sign muons' at three reference baselines is considered: 732 km, 3500 km, and 7332 km. We exploit the dependence of the signal on the neutrino energy, and include as well realistic background estimations and detection efficiencies. The optimal baseline turns out to be O (3000 km). Analyses combining the information from different baselines are also presented

    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 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.

  18. The Experience Factory: Strategy and Practice

    1995-01-01

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

  19. 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.

  20. Hospitals as factories of medical garbage.

    Science.gov (United States)

    Hodges, Sarah

    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.

  1. New Physics at a Super Flavor Factory

    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...

    Construction of the RIKEN RI Beam Factory is started, and the phase 1 will be finished by the end of March 2003. Two ring cyclotrons including one superconducting machine and two Big RIPSs will be constructed in the phase 1. Heavy ions of proton to uranium will be accelerated up to 400 MeV/u (A<40) and 150 MeV/u for uranium at an intensity of 10{sup 13} pps. Neutron production by the 400 MeV/u {sup 20}Ne beam was measured at HIMAC of NIRS and it was used for the source term of the shielding calculations. The deep penetration of high-energy neutrons was calculated by using the ANISN code with the DLC-119/HILO86R group constants and also by using the HETC code. The ANISN results were modified by using the HETC results and the shielding experiment at ISIS, and they were fitted by a simple formula for practical use. High-energy neutron penetrations of slantwise injection and the reflection probabilities of iron slab were calculated with the HETC code, and these results were used for the estimation of the thickness for the iron local shielding of Big RIPSs. Induced radioactivity in the air, accelerator components and the building, and the skyshine effect were also estimated. (author)

    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...

    {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.)

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.

    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).

  12. Make your company a talent factory.

    2007-06-01

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

  13. The Experiment Factory: standardizing behavioral experiments

    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.

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

  15. 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

    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.

    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 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.

  19. 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

    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.

  12. Design, analysis and presentation of factorial randomised controlled trials

    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.

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.

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

    Full Text Available Arthrospira are attractive candidates to serve as cell factories for production of many valuable compounds useful for food, feed, fuel and pharmaceutical industries. In connection with the development of sustainable bioprocessing, it is a challenge to design and develop efficient Arthrospira cell factories which can certify effective conversion from the raw materials (i.e. CO2 and sun light into desired products. With the current availability of the genome sequences and metabolic models of Arthrospira, the development of Arthrospira factories can now be accelerated by means of systems biology and the metabolic engineering approach. Here, we review recent research involving the use of Arthrospira cell factories for industrial applications, as well as the exploitation of systems biology and the metabolic engineering approach for studying Arthrospira. The current status of genomics and proteomics through the development of the genome-scale metabolic model of Arthrospira, as well as the use of mathematical modeling to simulate the phenotypes resulting from the different metabolic engineering strategies are discussed. At the end, the perspective and future direction on Arthrospira cell factories for industrial biotechnology are presented.

    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.

    Since about three or four years ago, the enterprises of machinery, iron and steel and welding materials in Japan are paying much attention to the acquisition of ASME (American Society of Mechanical Engineers) certificates or authorization to stamp the code symbols. That is, over 70 factories in Japan have undergone ASME examination, and consequently acquired the authorization or certificates. Such authorization is divided into over 20 kinds, of which about 7 are possessed by the companies in Japan. In nuclear field, the kinds of authorization are N (nuclear vessel), NPT (nuclear vessel parts), NV (nuclear vessel safety valve), and MM (material manufacturing). In non-nuclear fields, they are S (power boilers), U (pressure vessels, in Div. 1), and U2 (pressure vessels in Div. 2). The following matters are described: ASME setup, authorization procedures of ASME for factories, the kinds of authorization, factories in Japan holding the authorization or certificates, and renewal of the authorization.

    A conceptual design for an orbital factory sized to process 1.5 million metric tons per year of raw lunar fines into 0.3 million metric tons of manufacturing materials is presented. A conservative approach involving application of present earth-based technology leads to a design devoid of new inventions. Earth based counterparts to the factory machinery were used to generate subsystem masses and lumped parameters for volume and mass estimates. The results are considered to be conservative since technologies more advanced than those assumed are presently available in many areas. Some attributes of potential space processing technologies applied to material refinement and component manufacture are discussed.

Muon ionization cooling research is the key element of the program. The first muon ionization cooling demonstration experiment, MICE (Muon Ionization Cooling Experiment), is under construction now at RAL (Rutherford Appleton Laboratory) in the UK. The current status of MICE will be described.

    1980-01-01

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

    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).

    2012-01-01

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

    This paper reviews the motivation for building asymmetric B-factories based on storage rings and describes the current LBL/SLAC study to develop such a factory by modifying the PEP storage ring and adding a new low energy (2.5-3 GeV) storage ring. Collisions between the beam of the modified high energy PEP ring and the low energy ring lead to a luminosity of 2 x 10 33 cm- 2 sec - 1 at E cm = Y(4s) with currents of 0.8A in each beam. Further increases in current can lead to luminosities close to 10 34 cm - 2 sec - 1

    Full Text Available 1989 supuso para Argentina la llegada a la presidencia del justicialista Carlos Menem y el inicio de un sorprendente giro, dados los antecedentes de su partido, hacia políticas neoliberales. 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. El estudio de estas elecciones internas sirve así para explorar las continuidades y rupturas de la Argentina que abre un nuevo ciclo en 1989.Palabras clave: Argentina, peronismo, Menem, Renovación, elecciones, 1988___________________________ABSTRACT:1989 marked the arrival to the Argentinian presidency of the PJ Carlos Menem and the beginning of a surprising twist, considering the history of his party, towards neoliberal policies. As a preliminary step, however, Menem had to overcome in a primary election, in which he was disadvantaged compared to the favorite Antonio Cafiero, Governor of Province of Buenos Aires and leader of the so called “Peronist Renovation”. Menem's stunning victory in 1988 has been commonly explained as the result of society's reaction to the political class, in the context of crisis of the country, or as a result of the limits and shortcomings of the Cafiero’s political line. Without ignoring these approaches, in this paper we approach the

    Full Text Available O objetivo foi identificar fatores associados às admissões hospitalares no Brasil, analisando se essa utilização é eqüitativa e identificando características associadas aos grandes usuários. A PNAD/1998 foi analisada, utilizando regressão logística e regressão logística multinomial, com pesos normalizados e técnicas estatísticas para correção do efeito de desenho. O modelo teórico utilizado foi o Comportamental de Andersen. No modelo ajustado por necessidade de saúde e fatores capacitantes, pessoas com menor renda apresentaram maior chance de se internar; o contrário ocorreu no modelo ajustado somente por necessidade de saúde. Todas as variáveis de necessidade mostraram-se menos relacionadas ao uso nas pessoas com duas internações, em comparação com aquelas com mais do que duas internações. Não houve associação entre variáveis sociais e ocorrência de duas internações, mas essa associação ocorreu para três ou mais internações. A redução das desigualdades sociais nos aspectos que "capacitam" ao uso de admissões hospitalares reduziria as desigualdades neste uso. Um sistema de saúde que ofereça um "serviço de uso regular", além de baixo ou nenhum pagamento no ato do consumo, seriam medidas de impacto positivo na eqüidade do consumo de serviços hospitalares no Brasil.The objective was to identify hospital admission associated factors in Brazil, analyzing if that utilization is equitable and identifying which characteristics are associated with heavy users. We analyzed data from the 1998 National Household Survey, using logistic regression and multinomial logistic regression, with normalized weights and statistical techniques to correct for design effect. We used Andersen's Behavioral Model as the theoretical model for this analysis. In model adjusted for health needs and enabling factors, people with smaller income had more chance of being admitted to hospital; and in model adjusted only for health

    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.

    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.

  18. A factorial experiment on image quality and radiation dose

    International Nuclear Information System (INIS)

    Norrman, E.; Persliden, J.

    2005-01-01

    To find if factorial experiments can be used in the optimisation of diagnostic imaging, a factorial experiment was performed to investigate some of the factors that influence image quality, kerma area product (KAP) and effective dose (E). In a factorial experiment the factors are varied together instead of one at a time, making it possible to discover interactions between the factors as well as major effects. The factors studied were tube potential, tube loading, focus size and filtration. Each factor was set to two levels (low and high). The influence of the factors on the response variables (image quality, KAP and E) was studied using a direct digital detector. The major effects of each factor on the response variables were estimated as well as the interaction effects between factors. The image quality, KAP and E were mainly influenced by tube loading, tube potential and filtration. There were some active interactions, for example, between tube potential and filtration and between tube loading and filtration. The study shows that factorial experiments can be used to predict the influence of various parameters on image quality and radiation dose. (authors)

    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

Besides, in two study meetings held in October and December, 1989, several persons who have engaged in the research on B meson physics actually in foreign countries were invited, and the discussion was carried out. At present toward the materialization of the plan, the concrete investigation of accelerators and measuring instruments was begun. The significance of a B-factory and the construction project, the physics of a B-factory, the experimental method and the plan for an accelerator are reported. (K.I.)

    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. PMID:24351642

    Full Text Available This paper, by referring to the archaeological reports and local gazetteers and comparing images of porcelain wares, makes a comprehensive and in-depth analysis of the layout of power and space in Jingdezhen Imperial Factory according to its geography, geomancy, security management, space regulation, architectural features, production characteristics and production layout. It contends that the Imperial Factory which integrates porcelain making factory with local government is the embodiment of absolute monarchy in ceramic culture. The factory is located on Zhushan mountain, the center of Jingdezhen’s industry, business and transportation. Being at the center, it gives off an air of prestige and majesty, overlooking dominantly the surrounding private kilns. It has also turned the political system into power operation, setting up not only workshops but also administrative offices. By taking advantage of the best resources, it has produced porcelain for imperial family and court. Its specialized production has solved the contradiction between complicated technology and numerous procedures of production. The shape, color and pattern of the porcelain wares are strictly stipulated and the best of the best wares are demanded. Hence the porcelain production is featured with longest firing, largest scale, superb craftsmanship, and best kinds of wares. All of these reveal the process and rule power and space are intersected and different cultures overlapped.

    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.

  9. Transcriptomal profiling of bovine ovarian granulosa and theca interna cells in primary culture in comparison with their in vivo counterparts.

    Directory of Open Access Journals (Sweden)

    Nicholas Hatzirodos

    Full Text Available In vitro culture of ovarian granulosa cells and theca cells has been very important for our understanding of their function and regulation. One of the most eagerly sought attributes of cell culture is the use of chemically-defined conditions. However, even under such in vitro conditions cell behaviour could differ from the in vivo situation because of differences in oxygen tension, nutrients, adhesion matrix and other factors. To examine this further we compared the transcriptomes of both granulosa cells and cells from the theca interna that were cultured in what are arguably the best in vitro conditions for maintaining the 'follicular' phenotypes of both tissue types, as displayed by their respective freshly-isolated counterparts. The array data analysed are from recently published data and use the same sizes of bovine follicles (small antral 3-6 mm and the same Affymetrix arrays. We conducted analysis using Partek, Ingenuity Pathway Analysis and GOEAST. Principal Component Analysis (PCA and hierarchical clustering clearly separated the in vivo from the in vitro groups for both cells types and transcriptomes were more homogeneous upon culture. In both cell cultures behaviours associated with cell adhesion, migration and interaction with matrix or substrate were more abundant. However, the pathways involved generally differed between the two cell types. With the thecal cultures a gene expression signature of an immune response was more abundant, probably by leukocytes amongst the cells cultured from the theca interna. These results indicate differences between in vivo and in vitro that should be considered when interpreting in vitro data.

  10. Phenomenology of neutrino oscillations at the neutrino factory

    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

    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.

    1990-02-01

    A computer program has been developed in order to simulate the energy consumption of beet sugar factories, for various plant configurations. The program is divided into five block units: Extraction and Juice purification, Juice concentration, Crystallization, Drying and finally the Power House. Each block consists of different modules, for example, a heat exchanger, an evaporator, a turbine and a dryer. The purpose of this project was to simulate some different system configurations of a sugar factory, whereby both new and previously used process technologies were utilized. The following parts of the process have been particularly emphasized: Power House - gas turbine, waste heat boiler. Drying - low-temperature dryer, steam dryer. Evaporation - vapour recompression. Crystallization - vapour recompression, continuous system. The different plant configurations have been compared to a reference factory, which is designed according to current technology used in a modern and well balanced Swedish factory. The comparisons are based upon the total power consumption as well as the total annual energy costs. Eleven different plant configurations were studied. The maximum power reduction is 36%, relative to the reference factory. The dissertation also contains an experimental study of a low-temperature drying process. The drying characteristics of pressed beet pulp were studied in a specially designed rotary dryer pilot plant. A number of parameters were varied i.e. the solid moisture content, air velocity, temperature and rotational speed. The results are given in terms of an apparent volumetric heat-transfer coefficient, determined from measured data. A mathematical model was established to determine the residence time of the material in the rotary dryer at different air velocities. (45 refs.).

    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.

    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

  5. Collimation issues for the PEP-II B-factory

    International Nuclear Information System (INIS)

    Sullivan, M.

    1997-12-01

    This note describes how beam collimation affects detector backgrounds at the collision point for the PEP-II B-factory, a joint effort of three laboratories: LBNL, LLNL, and SLAC. Beam collimation controls the transverse size as well as the maximum allowed energy spread of the beam. The location of synchrotron radiation masks is determined by the transverse size of the beam in that the masks must prevent radiation generated by beam particles located at large transverse beam positions from directly striking the detector beam pipe. Collimation of the energy spread of the beam is important in the control of backgrounds produced by beam particles that strike a gas molecule (lost beam particles). The author describes some preliminary information from background studies during the first months of commissioning the high energy ring of the PEP-II B-factory and present some model predictions for synchrotron radiation backgrounds when collimators are not present

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

    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.

    2007-01-01

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

    The 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.

  14. A large magnetic detector for the neutrino factory

    International Nuclear Information System (INIS)

    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

  15. SEARCH FOR NEW PHYSICS AT A SUPER-B FACTORY.

    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.

  16. R and D Toward Neutrino Factories and Muon Colliders

    Zisman, Michael S.

    2003-01-01

    R and D aimed at the production, acceleration, and storage of intense muon beams is under way in the U.S., in Europe, and in Japan. Considerable progress has been made in the past few years toward the design of a ''Neutrino Factory'' in which a beam of 20-50 GeV mu- or mu+ is stored. Decay neutrinos from the beam illuminate a detector located roughly 3000 km from the ring. Here, we briefly describe the ingredients of a Neutrino Factory and then discuss the current R and D program and its results. A key concept in the design is ''ionization cooling,'' a process whereby the muon emittance is reduced by repeated interactions with an absorber material followed by reacceleration with high-gradient rf cavities. Plans to test this concept in the Muon Ionization Cooling Experiment (MICE) are well along and are described briefly

    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.

  19. 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

    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.

    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.)

    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

  9. Comments on particle identification at the B factory

    International Nuclear Information System (INIS)

    Ratcliff, B.N.

    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

    The heights of the magnets for both the ring and the beam transport line (BT-line) have been periodically measured at the Photon Factory. The accumulated data showed that the ring was considerably declined due to the construction of the large experimental hall and the tunnel of the TRISTAN project, and that the BT-line also sank several centimeters at some locations. These displacements of the magnets produce a significantly large closed orbit distortion and the vertical dispersion

  12. Synchrotron radiation leakage from the B-factory beam pipe

    International Nuclear Information System (INIS)

    Jenkins, T.M.; Nelson, W.R.; Ipe, N.

    1990-01-01

    The high-energy ring (HER) of the B-Factory, running at an energy of 9 GeV, generates the synchrotron spectrum when applied to a ring with the PEP bending radius. The B-Factory HER may also run at 12 GeV, producing the harder spectrum. Depending upon beam-pipe material and thickness, some of this radiation may escape and deposit energy in the surrounding material. This was originally pointed out in PEP-109 during the initial design of PEP, and subsequently verified by measurements at both PEP and PETRA at DESY. Of concern to the B Factory is magnet insulation, though other adjacent materials such as wire insulation and cooling water hoses are even more radiosensitive. Radiation damage to magnets is a function of the type of material used in the potting compound. The PEP magnets, which hopefully can be used for the high-energy ring of the B-Factory, are insulated with an epoxy composed of DER-332, DER-732, NMA and aluminum oxide. It is estimated that this epoxy compound should tolerate doses near the 10 10 rad range. To summarize the results of these calculations, 0.87 cm of copper is needed at the point of maximum dose from 12-GeV operation in order to reach the dose criterion if a rectangular beam pipe is used. The copper needs to be only 0.7-cm thick for an octagonal beam pipe and the same energy. For 9-GeV operation, an octagonal copper pipe needs only to be 0.25-cm thick. An octagonal aluminum pipe that is 0.5-cm thick also needs 0.3 cm of lead on the outside to reach the same criterion for 12-GeV operation. For 9-GeV operation, the aluminum pipe still requires a lead liner

    A preliminary design for a B-factory has been made using asymmetric collisions between positrons in the PEP storage ring and electrons in a new, log-energy ring.

    Full Text Available Introducción: La especialidad de medicina interna enfrenta muchos retos para permanecer competitiva en el sistema de salud, siendo el escaso conocimiento del público sobre la definición, capacidades y competencias de la medicina interna y del internista uno de esos retos. Objetivos: Determinar cuáles son los conocimientos y la percepción de los pacientes sobre el rol de la medicina interna y del médico internista. Diseño: Estudio transversal, descriptivo y analítico. Lugar: Hospital Nacional Arzobispo Loayza, Hospital Nacional Edgardo Rebagliati y una clínica privada. Participantes: Pacientes adultos que visitaron los servicios de Medicina interna de los tres hospitales. Intervención: Se invitó a llenar un cuestionario anónimo y autoadministrado a los participantes entre el 1 y el 15 de septiembre de 2008. Principales medidas de resultados: Nivel de conocimiento sobre medicina interna e internista, percepción de confianza hacia el internista. Resultados: Quinientos pacientes completaron el cuestionario, 42,8% del Hospital Loayza, 40% del Hospital Rebagliati y 17,2% de una clínica privada. Solo 12,2% alcanzó un buen nivel de conocimiento. El 79% de pacientes tuvo percepción de confianza en el internista para el manejo de síntomas, 50,2% confió en la habilidad clínica del internista y 45,9% confió en el manejo de las enfermedades específicas. Conclusiones: Los pacientes no tienen una definición clara de la medicina interna y el rol del internista. La percepción de confianza es alta con respecto al manejo de los síntomas, pero disminuye al tratarse de enfermedades específicas y de las habilidades clínicas del internista. Por lo tanto, debe realizarse esfuerzos de educación pública para mejorar el entendimiento del rol del internista como especialista en medicina de adultos.
