    Apesar das pesquisas com sistemas silvipastoris terem sido iniciadas no final da década de 1970, as informações geradas até hoje não são em grande número. As vantagens advindas de um sistema silvipastoril são inúmeras e devidamente reconhecidas. Pelo fato de ser uma técnica de uso da terra capaz de recuperar ecossistemas alterados pelo mau manejo, estes sistemas, pela integração de atividades agrícolas, pecuárias e silviculturais, passam a representar uma tecnologia que confere maior sustentabilidade que os sistemas tradicionais, nos quais os monocultivos são predominantes. Nos últimos anos, instituições de ensino, pesquisa e extensão do País têm se voltado para o desenvolvimento de tais sistemas. O governo de Minas Gerais, por meio de sua Secretaria de Estado de Agricultura e de órgãos vinculados, vem promovendo a condução de modelos agrossilvipastoris num processo integrado de ocupação do solo, denominado lavoura-pecuária-silvicultura. Apesar dos grandes avanços no conhecimento de culturas anuais e dos componentes arbóreos, principalmente o eucalipto, e de gramíneas forrageiras tolerantes à diminuição da intensidade luminosa, ainda é necessário se comnhecer melhor o manejo do sub-bosque sob os efeitos do pastejo.

    Although researches related to silvopastoral systems have been initiated many years ago in Brazil, there are few informations generated until now. The advantages from a silvopastoral system are inumerous and well recognized. By the fact of being a technique of land using capable of recovering several disturbed ecosystems, the silvopastoral systems by the integration of agricultural, cattle, and silvicultural activities represent a technology that can achieve higher sustainability than the traditional systems as the monocultures. Today, research centers in Brazil dedicate great attention to agrossilvopastoral systems. The government of Minas Gerais

    Due to poor yielding capacity in the province of Catamarca, Argentina, it is necessary to improve solar drying systems in order to have a better quality final product. It is also essential to divide the costs of infrastructure with other complementary activities because of the need to make drying methods profitable. The system proposed in this work is a dryer-greenhouse with a double purposed macrotunnel greenhouse: during Winter it is used as a yielding system, and in Summer it is prepared to fulfill the functions of a solar dryer. The crops evaluated in winter were: small vegetable marrow (Curcubita maxima L), melon (Cucumis melo), ad cucumber (Cucuis sativus). Crop cycle, harvest time and tield in Kg/m were determined for each species. The assessment of the dryer was made using pepper for paprika observation of the thermal behavior of the product during drying and its final quality. The product obtained had a very good quality in color, taste and aroma with a classification of extra quality according to the Argentine Nutritional Code and the 7541 ISO Standard. Drying time decreased considerably compared to that observed in open air drying, 1995, 1996 and 1997 campaigns were economically assessed, and an evaluation of investments in five years was also conducted obtaining a positive VAN and a TIR above the cost of the best alternative for money expenditure. This integrated system is valid alternative in a sustainable production for small growers.

Este trabalho propõe uma abordagem sistêmica para uma etapa anterior à execução da integração, ou seja, para quando do estudo da viabilidade e elaboração de projeto. A matemática pode servir de suporte para que uma decisão não seja emocional no sentido da organização buscar seu Sistema Integrado de Gestão para estar acompanhando a tendência de seus concorrentes, mas que passe a ser racional na decisão de por que, quando, quanto, como e que sistemas integrarem. Uma vez decidindo-se pela integração de certo número de sistemas de gestão, encontrar-se-ão áreas de atividades que poderão ser enxugadas e outras que não, e estas últimas disputarão mais pelos recursos. Para reduzir o conflito e buscar a solução ótima, é proposta a aplicação de Programação Matemática.It can be observed that there is a gap between the moment of the decision to adopt an Integrated Management System and its effective implementation. To address this problem, the present work proposes a systemic approach to the stage prior to the implementation of the integration, that is, when of the study of viability and project elaboration is being carried out. Mathematics can give support to the decision making as it is not emotional in the sense of the company using the Integrated Management Systems search just to be up-to-date with its competitors; mathematics makes the decision of why, when, how much, how and which systems to be integrated rational. When the decision to integrate certain management systems has been made, it will be clear that some activities may be pared and others not, thus reducing the competition for resources. Mathematical programming is proposed to reduce the conflict and to search for the optimum solution.

    The study and modeling of corrosion processes aim at the accomplishment of three primary objectives: to increase safety operation margins, to reduce maintenance costs and to optimize available resources. The Integrity Expert System is based on a statistical propagation model of defects reported by high resolution magnetic inspection tool (MFL), fed with the information provided by corrosion sensors, repair interventions, field surveys and future inspections. As model results, defect depth, remaining strength and failure probability distributions were obtained. From the analysis, feasible courses of action were established: a medium term repair plan, an internal inspection program and both monitoring and mitigation technologies. System implementation in OLDELVAL was translated into two major effects of importance for the company integrity program: reduction in the pipeline probability of failure by corrosion by means of programmed repairs and optimization of the internal inspection investment plan by mans of an alternative programming.

[Spanish] Sin duda, la energia electrica es la forma de energia mas ampliamente usada en las actividades economicas y sociales de nuestro mundo moderno. Por ello, se puede decir que las companias generadoras y distribuidoras de electricidad asumen dos retos de relevante preocupacion actual. Uno es generar con mayor eficiencia, menor costo y con un minimo impacto sobre el medio ambiente. El segundo es cumplir con la calidad del suministro, que ha llegado a ser un punto importante tanto para los usuarios como para las companias que distribuyen la energia electrica, y que se refleja en una distribucion y un consumo de energia mas eficiente. El trabajo de tesis que se presenta, describe un sistema fotovoltaico (SFV) interconectado a la red electrica que ayuda a superar los retos citados. Este SFV tiene la funcion de recibir la energia solar entregada por un arreglo de celdas FV; operar en el punto maximo de potencia de las celdas (para mayor aprovechamiento de la energia captada); acondicionarla a una senal alterna, dentro de los parametros tecnicos normativos para la interconexion electrica (establecidos por la compania; Comision Federal de Electricidad en Mexico); e inyectarla a la red electrica con el proposito de compensar potencia reactiva (filtrado activo) demandada por cargas lineales y no lineales, reduciendo la contaminacion de la red electrica; ademas de compensar potencia activa en los picos de demanda de energia electrica maxima.

    The lack of a computational aided technology to support short-term scheduling activity in the oil and petrochemical sector has been identified as one of the major obstacles to the harmonic integration of production objectives subsequent to the implementation of the advanced control systems and the consolidation of important benefits at the process unit level. Such technology refers to an analytical tool able to capture plant operational information consistent with the scheduling layer demands, modeling the production system economic performance, and providing mechanisms to consider commercial, operation and technological uncertainties. In this context, PETROBRAS has continuously dedicated effort to develop, implement and enhance its own refinery scheduling solution. Nowadays at its second version, the PETROBRAS Integrated Scheduling System (BR-SIPP - INPI grant 00067400) has become the focus of corporate care, given its critical role on the link between planning objectives and plant operations, according to the hierarchical decision strategy currently adopted by PETROBRAS. This paper presents an overview of the tool and illustrates some real-world applications and main realized benefits. (author)

    Deep and ultra-deepwater Exploration and Production activities offshore Brazil have become a reality, corresponding nowadays to the majority of the national production. In order to make oil and gas production viable in this kind of environment, complex systems are used, requiring very strong investments, as well as equipment with high reliability requirements, to assure the benefits of the high productivity of the fields. The production flow systems comprise rigid and flexible pipelines, umbilicals and subsea equipment, to which high costs are associated regarding inspection, maintenance and intervention activities. Besides this, social claims through actions by regulatory agencies are getting stricter with time, as they increase their control of aspects related to safety and environmental impact aspects. In this scenario, PETROBRAS, through its Exploration and Production Business Unit in Rio de Janeiro (UN-RIO), signed a service contract with Det Norske Veritas (DNV). The development and application of specific methodologies for risk and reliability analysis, as well as the development of a specific software, are included in this project. (author)

    This work is aim to hydrological and environmental characterization of Langueyu stream basin, where Tandil city is located. This basin is developed on northern hillside of Tandilia system, in Buenos Aires province, and it drains to NE. There are two different hydrogeological units: crystalline rocks and Cenozoic sediments, which correspond with two hydrolithological characters, fissured and clastic porous, respectively. The population is supplied by groundwater sources. Water exploitation and use were analyzed, according to the growing demands from industrial, agricultural and urban uses. The impacts of intense exploitation were evaluated. High levels of nitrate were corroborated in older wells of the city, which nowadays are in use. The hydrodynamic change in a section of the stream, where it converts to influent, was detected. This disturbance of the natural relation could be a potential source of contamination to the aquifer, due to high charges of industrial and urban effluents which the stream receives. Several population sectors, which have neither a drinking water net nor a sewer system, showed microbiological and chemical water contamination. Other water impact is constituted by several abandoned quarries which have historically received wastes, mainly from foundry industries. In conclusion, water management basin does not aim to sustainable development, due to its lack of integration. It demands the knowledge of hydrological system, according with the goal to avoid water quality degradation and to guarantee its protection. (Author).

Essas equipes tinham o objetivo de potencializar as ações do PSF e de garantir a integralidade da atenção na promoção, prevenção, assistência e reabilitação. Um das dificuldades encontradas no processo de trabalho dessas categorias foi a ausência de um sistema de informação que contemplasse o registro de atividades executadas pelas equipes. Entendendo que a informação representava um espaço importante para o desenvolvimento e a produção de saúde, um grupo foi formado para elaborar um instrumento e software para o sistema de informação. Esse grupo era composto de profissionais da Secretaria Municipal de Saúde, do setor de informática do município e residentes da Escola de Saúde da Família. O instrumento criado continha os perfis da população assistida, o registro de atividades e procedimentos realizados e os agravos de notificação que estavam sendo definidos. Depois da criação do instrumento, foi desenvolvido o software em Sistema Operacional Linux, linguagem de programação PHP, banco de dados POSTGRESQL e foi acomodado em um servidor web Apache.

Esto es resultado y causa de las desigualdades sociales que han caracterizado el proceso de desarrollo en México. Varias limitaciones estructurales han dificultado el funcionamiento y limitado el avance de su sistema de salud. Consciente de que la falta de protección financiera era su principal debilidad, México ha emprendido una reforma estructural para mejorar el desempeño del sistema de salud mediante el establecimiento del Sistema de Protección Social en Salud (SPSS, el cual ha introducido nuevas reglas de financiamiento e incentivos. La principal innovación de la reforma ha sido el Seguro Popular de Salud, el componente de aseguramiento del SPSS dirigido al financiamiento de la atención médica para todas aquellas familias, en su mayoría pobres, que históricamente habían sido excluidas de la seguridad social. La reforma ha permitido un incremento significativo en la inversión pública en salud, al tiempo que realinea los incentivos para garantizar una atención de mayor calidad técnica e interpersonal. En este trabajo se describen las principales características y los resultados iniciales de este esfuerzo de reforma de México, y se derivan algunas lecciones para otros países que consideren llevar a cabo transformaciones a su sistema de salud en circunstancias de desafío similares.Despite having achieved an average life expectancy of 75 years, much the same as that of more developed countries, Mexico entered the 21st century with a health system mared by its failure to offer financial protection in health to more than half of its citizens; this was both a result and a cause of the social inequalities that have marked the development process in Mexico

    Full Text Available Nowadays is recognized that the agriculture goes beyond that only the food production, so the concept of agricultural multifunctionality is introduced in order to describe this fact, recovering the true sense of the agriculture, and classifying its functions in three groups: 1 food security, 2 environment, and 3 socio-cultural. In each one of these functions, the agricultural production systems generate two categories of products: a the traditional outputs (commodities, such as food, fibers and energy, and b the non traditional outputs (non-commodities, which included aspects related with the environment and territory, employment, human resources and work, food safety and quality, animal welfare, food security and economic autonomy of the rural regions among others. Finally, we explore the evolution that agricultural production systems have had from a productivist focus toward a model where the new paradigm is the multifunctional agriculture, where the developing countries could have an important place.El presente artículo inicialmente aborda el concepto de multifuncionalidad de la agricultura, donde encontramos que actualmente se reconoce que la agricultura va mas allá de la simple producción de alimentos, clasificando sus principales funciones en tres ejes temáticos: 1 seguridad alimentaria, 2 medio ambiente, y 3 socio-cultural. En cada una de estas funciones se evidencia que los sistemas de producción agropecuaria generan dos categorías de productos: a productos tradicionales (“commodities”, como son los alimentos, las fibras y la energía, y b productos no tradicionales (“non-commodities”, los cuales incluyen aspectos relacionados con el medio ambiente y territorio, la generación de empleo, el manejo del recurso humano y de las condiciones laborales, la gestión de la calidad de los alimentos, el bienestar animal, la autonomía económica de las regiones rurales y su seguridad alimentaria, entre otros.

    Full Text Available The objective of this work was to assess the effects of integrated crop-livestock systems, associated with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four different management systems were studied: continuous pasture (mixed grass; continuous crop; two crop-livestock rotations (crop/pasture and pasture/crop; and native Cerrado as a control. Macrofauna was sampled using a modified Tropical Soil Biology and Fertility method, and all individuals were counted and identified at the morphospecies level for each plot. A total of 194 morphospecies were found, distributed among 30 groups, and the most representative in decreasing order of density were: Isoptera, Coleoptera larvae, Formicidae, Oligochaeta, Coleoptera adult, Diplopoda, Hemiptera, Diptera larvae, Arachnida, Chilopoda, Lepidoptera, Gasteropoda, Blattodea and Orthoptera. Soil management systems and tillage regimes affected the structure of soil macrofauna, and integrated crop-livestock systems, associated with no-tillage, especially with grass/legume species associations, had more favorable conditions for the development of "soil engineers" compared with continuous pasture or arable crops. Soil macrofauna density and diversity, assessed at morphospecies level, are effective data to measure the impact of land use in Cerrado soils.O objetivo deste trabalho foi avaliar os efeitos de sistemas de integração lavoura-pecuária, associados a dois tipos de preparo e de fertilização do solo, sobre a abundância e a diversidade da macrofauna edáfica.

    The paper presents a view of systems integration, from an ergonomics/human factors perspective, emphasising the process of systems integration as is carried out by humans. The first section discusses some of the fundamental issues in systems integration, such as the significance of systems boundaries, systems lifecycle and systems entropy, issues arising from complexity, the implications of systems immortality, and so on. The next section outlines various generic processes for executing systems integration, to act as guides for practitioners. These address both the design of the system to be integrated and the preparation of the wider system in which the integration will occur. Then the next section outlines some of the human-specific issues that would need to be addressed in such processes; for example, indeterminacy and incompleteness, the prediction of human reliability, workload issues, extended situation awareness, and knowledge lifecycle management. For all of these, suggestions and further readings are proposed. Finally, the conclusions section reiterates in condensed form the major issues arising from the above.

    Solar linear concentration technologies to generate high temperatures are limited to the ranges of 200 to 500 degrees Celsius. While its performance has been tested through prototypes and pilot plants around the world, there are still areas of opportunity that can be exploited to obtain a linear concentration that achieves temperatures above this range in order to have a better use of the available solar energy. Because of this: It is possible to develop a linear concentration system that can track the sun with minimal movement of the absorber-receiver while maintaining temperatures above 850 degrees Celsius sufficient for industrial processes that require that temperature. The methodology consists of a series of stages (conceptual design, simulation, evaluation, development concept, results and validation) through which concepts are generated that allow design and evaluation of solar concentrator configurations with the help of simulation software. We have designed a linear parabolic concentrating system which comprises a set of mirrors segments with different focal lengths that works within the range of 600 degrees Celsius; however, it is advancing in the development of a double concentration to reach 850 degrees Celsius. [Spanish] Las tecnologias de concentracion lineal solar para generar altas temperaturas se ven limitadas a los rangos de 200 a 500 grados centigrados. Si bien su funcionamiento ha sido probado a traves de prototipos y plantas piloto alrededor del mundo, aun existen areas de oportunidad que pueden ser aprovechadas para obtener un sistema de concentracion lineal que permita alcanzar temperaturas mayores a este rango para asi tener un mejor aprovechamiento de la energia solar disponible. Debido a esto: Es posible desarrollar un sistema de concentracion lineal capaz de seguir la trayectoria del Sol con minimo movimiento del absorbedor-recibidor al mismo tiempo que mantiene temperaturas superiores a los 850 grados centigrados suficientes para

    Full Text Available Se desarrolló un prototipo de un sistema integral para la clasificación de coberturas y usos de la tierra, aplicable a los sistemas bananeros. Este se basó en dos criterios, el de la participación comunitaria y el del sensoramiento remoto. El primero se fundamenta en la incorporación del conocimiento que tiene la comunidad de su entorno mediante talleres y cartografía social, el segundo propone el empleo de herramientas tecnológicas de bajo costo para el levantamiento de las coberturas y uso de la tierra, como la adquisición de fotografías aéreas de baja altitud usando un sistema conformado por una cometa o globo, un equipo para la adquisición de las imágenes y un equipo de control en tierra. La propuesta fue aplicada mediante un estudio de caso en una finca bananera ubicada en la región de Urabá (Colombia. El análisis de imágenes permitió la agrupación de las coberturas en clases o grupos y con el aporte de la participación comunitaria se describieron los usos para cada cobertura. Finalmente se hizo un análisis de las normas ambientales relacionadas con la distribución espacial de las coberturas, hallándose por ejemplo áreas de retiro del cultivo respecto a recursos o zonas vulnerables así como su cumplimiento o no de la normatividad.An integrated system was developed for the classification of land cover and use that is applicable to banana systems. It was based on two criteria; community participation and remote sensing. The former is based upon incorporation of the knowledge that the community has regarding its surroundings through workshops and social cartography; the latter proposes the use of low cost technological tools for establishing land covers and uses, such as acquiring low altitude aerial photographs using a system comprised of a kite or balloon, equipment for image acquisition, and ground based control equipment.

    Full Text Available El envejecimiento del sistema cardiovascular está asociado con un número característico de cambios a nivel bioquímico, histológico y morfológico. Sin embargo, no todas las modificaciones presentadas se asocian con deterioro en la función. Entre los cambios a nivel cardiaco se tienen: disminución en el número de miocitos y en las células del sistema de conducción cardiaca, desarrollo de fibrosis, cambios en el transporte de calcio a través de las membranas y disminución del cronotropismo, inotropismo y lusitropismo mediados por estímulo b-adrenérgico. A nivel vascular, hay incremento en la rigidez de la pared de las arterias, con aumento en la velocidad de la onda de pulso, disfunción endotelial y disminución de la vasodilatación mediada por estímulo b-adrenérgico. Durante el reposo el sistema cardiovascular es capaz de desarrollar mecanismos adaptativos eficientes, pero en situaciones de estrés como el ejercicio, los cambios asociados con el envejecimiento se hacen evidentes ya que está disminuida la capacidad para obtener la frecuencia cardiaca máxima, está incrementada la postcarga y hay disminución de la contractilidad intrínseca. Por lo anterior, los ancianos deben utilizar al máximo el mecanismo de Frank-Starling para mantener el gasto cardiaco. Los cambios estructurales y funcionales asociados con el envejecimiento cardiovascular, disminuyen de forma significativa el umbral en el cual las enfermedades cardiacas llegan a ser evidentes, y deben ser conocidos por el personal de salud encargado de cuidar a los ancianos.Cardiovascular aging is associated with characteristic biochemical, histological and morphological changes.

    This paper presents the development of an integrated simulation model, for the numerical calculation of thermal-hydraulic behaviors in the Brazilian southeast onshore gas pipeline flow system, remotely operated by TRANSPETRO's Gas Pipeline Control Centre (CCG). In its final application, this model is supposed to provide simulated results at the closer range to reality, in order to improve gas pipeline simulation studies and evaluations for the system in question. Considering the fact that numerical thermo-hydraulic simulation becomes the CCG's most important tool to analyze the boundary conditions to adjust the mentioned gas flow system, this paper seeks and takes aim to the optimization of the following prime attributions of a gas pipeline control centre: verification of system behaviors, face to some unit maintenance stop or procedure, programmed or not, or to some new gas outlet or inlet connection to the system; daily operational compatibility analysis between programmed and realized gas volumes; gas technical expedition and delivery analysis. Finally, all this work was idealized and carried out within the one-phase flow domain (dry gas) (author)

O artigo aborda os sistemas de gestão da empresa industrial, particularmente os de gestão econômica, e as novas necessidades decorrentes do surgimento e da adoção de novos modelos de organização da produção. Considerando que, nas atuais empresas industriais, as características de desempenho estão sofrendo radical mudança, o autor procura traçar um quadro preciso dessas transformações, mostrando que os sistemas tradicionais de gestão - baseados na contabilidade analítica e moldados de acordo com a lógica clássica de organização - não correspondem às novas exigências quanto ao desempenho e não se coadunam com o tipo de organização que vem sendo implementado. A originalidade da contribuição do autor consiste em associar organização e gestão, pondo em foco a necessidade de se instaurar uma nova coerência entre estrutura de organização e sistema de gestão.This article constitutes a version of Professor Philippe Zarifian's paper, presented under the same title at the International Workshop "Where do organizations go to?", promoted (sponsored by the Departamento de Engenharia de Produção of the Escola Politécnica of the Universidade de São Paulo, in August 1994.

    This work describes a model capable of including non-conventional energy sources into a stochastic energy production model for conventional power sources. A wind energy system is initially considered as statistically independent of the hourly demand. The correlation between two wind systems is then considered by means of a joint wind speed distribution. The joint wind system is thereafter submitted to the stochastic energy production model considering independence between demand and wind speed. Finally the correlation wind systems and the hourly demand is studied. (author). 29 figs, 31 tabs

The summer crops soybean (Glycine max (L. Merr. or corn (Zea mays L., as antecedent crop in rotation to the winter pastures, were also studied to measure the increasing or decreasing effects on compaction by animal trampling. The greatest effects of animal trampling were concentrated in the top soil layer (0 to 0.05 m, but under the highest grazing frequency (G14 macroporosity was reduced down to the 0.10-0.15 m layer. The soil resistance to penetration had peaks of 2.61 and 2.49 MPa in the G28 and G14 treatments, respectively, in the 0.05-0.08 layer. In the ungrazed areas the values remained lower, around 1.66 MPa. Soil water infiltration was significantly affected by animal trampling and by the previous summer crop. In the case of corn area, the soil was less sensitive to cattle trampling, unlike in the areas following soybean, where the highest grazing frequency (G14 reduced the water infiltration rates. Soybean induced higher values of macroporosity in the evaluated soil layers; when related with lower beef cattle density or ungrazed pastures, the rates of water infiltration and accumulated infiltration were higher.

    The turbine wheels undergo high thermal and mechanical stresses caused by the requirements of their operation. This causes a mechanical damage (fatigue) that is accumulated according to the frequency whereupon the different operation ways (cold starts, lukewarm or hot) happen. On the other hand, the greater efficiency of power stations of combined cycle with respect to conventional power stations is reflected in a greater production cost of the electrical energy, which has forced to that conventional generation units designed to operate on base load, now are used as variable load units to satisfy the demand during the peak hours. The former, rebounds in a greater frequency of operations of shut downs and hot starts of turbines, reason why the fatigue damage will be increased when changing its operating range. In Mexico turbines there are turbines that have been 15 or 20 years in operation and that do not have a thermal stresses supervisor, reason why when changing their load operation from base load to variable load it is essential to install a rotor supervisor of thermal efforts, with the purpose of limiting or reducing the thermal stresses and in this way reduce the fatigue damage to extend their useful life. The article deals over the integration of a supervisory system of thermal stresses, that from the operation parameters of the turbine, determines the temperature gradient in the labyrinth seals zone between the control passage and the first passage of the high pressure section of the rotor, the thermal and mechanical stresses and the fatigue are calculated, determining the consumption of the useful life for each operation cycle (shutdown and starting).

    Full Text Available The Diagnosis and Recommendation Integrated System (DRIS can improve interpretations of leaf analysis to determine the nutrient status. Diagnoses by this method require DRIS norms, which are however not known for oil content of soybean seeds. The aims of this study were to establish and test the DRIS method for oil content of soybean seed (maturity group II cultivars. Soybean leaves (207 samples in the full flowering stage were analyzed for macro and micro-nutrients, and the DRIS was applied to assess the relationship between nutrient ratios and the seed oil content. Samples from experimental and farm field sites of the southernmost Brazilian state Rio Grande do Sul (28° - 29° southern latitude; 52° -53° western longitude were assessed in two growing seasons (2007/2008 and 2008/2009. The DRIS norms related to seed oil content differed between the studied years. A unique DRIS norm was established for seed oil content higher than 18.68 % based on data of the 2007/2008 growing season. Higher DRIS indices of B, Ca, Mg and S were associated with a higher oil content, while the opposite was found for K, N and P. The DRIS can be used to evaluate the leaf nutrient status of soybean to improve the seed oil content of the crop.O Sistema Integrado de Diagnose e Recomendação (DRIS pode melhorar a interpretação da análise foliar, contribuindo com a avaliação do estado nutricional.

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

  12. Searching for integrable systems

    International Nuclear Information System (INIS)

    Cary, J.R.

    1984-01-01

    Lack of integrability leads to undesirable consequences in a number of physical systems. The lack of integrability of the magnetic field leads to enhanced particle transport in stellarators and tokamaks with tearing-mode turbulence. Limitations of the luminosity of colliding beams may be due to the onset of stochasticity. Enhanced radial transport in mirror machines caused by the lack of integrability and/or the presence of resonances may be a significant problem in future devices. To improve such systems one needs a systematic method for finding integrable systems. Of course, it is easy to find integrable systems if no restrictions are imposed; textbooks are full of such examples. The problem is to find integrable systems given a set of constraints. An example of this type of problem is that of finding integrable vacuum magnetic fields with rotational transform. The solution to this problem is relevant to the magnetic-confinement program

    Full Text Available Se ha demostrado que el ejercicio hecho a diferentes intensidades cumple una función moduladora sobre diversos sistemas, y que su acción sobre la respuesta inmune es de gran importancia. Por lo tanto, es necesario esclarecer si estos cambios constituyen efectos benéficos o perjudiciales en cuanto a las adaptaciones del hospedero frente a diversos agentes patógenos. El estudio de estos cambios inducidos por el estrés físico puede tener un impacto grande en la comprensión y prevención de algunas enfermedades que involucran la respuesta del sistema inmune como las alergias, las infecciones, las inmunodeficiencias y el cáncer. En este artículo se presenta una revisión actualizada de la información existente al respecto, con el propósito de aportar elementos que ayuden a comprender este fenómeno biológico, así como sus implicaciones para la salud humana. Se han estudiado varios parámetros de la respuesta inmune durante el ejercicio físico, entre ellos su relación con la respuesta hormonal al estrés y el comportamiento de las diferentes hormonas de acuerdo con la intensidad de aquél. También se han evaluado los cambios en las poblaciones de células sanguíneas (linfocitos, monocitos y neutrófilos así como el comportamiento de las citoquinas y la síntesis de inmunoglobulinas específicas. Todo esto ha permitido establecer una relación entre los sistemas inmune y neuroendocrino, la cual explicaría en It has been demonstrated that physical exercise, carried out at diverse intensities, modulates the function of different human body systems, and that it plays a major role in the immune response. Therefore, it is necessary to find out if these changes have benefic or harmful effects on the host adaptation against several pathogenic agents. The study of these physical-stress-induced changes might have a great impact on the comprehension and prevention of some diseases that involve activation of the immune system such as allergies

Os artigos foram identificados a partir das bases de dados MEDLINE e LILACS, usando as palavras-chave "córtex supra-renal", "pele", "massagem", "lactentes", "glicocorticóide" e "ritmo circadiano". O período pesquisado foi de 1990 a 2003. Foram também consultados artigos de destaque publicados antes desse período. Estudos reconhecem o hipotálamo, a hipófise e a glândula adrenal como órgãos dinâmicos durante o desenvolvimento fetal e neonatal, e que respostas de estresse estão presentes ao nascer. A maioria dos estudos revisados, utilizando a estimulação tátil-cinestésica, seja em humanos ou animais, evidencia a capacidade da pele em metabolizar, coordenar e organizar estímulos externos, procurando manter a homeostase interna e externa, demonstrando a interação entre sistema neuroendócrino e a pele. A estimulação tátil-cinestésica parece ter um efeito sobre a reatividade hormonal, porém essa questão merece uma investigação mais aprofundada.A literature review on skin neuroendocrine aspects and the consequences of the tactile- kinesthetic stimulation on the adrenal cortex are presented. The articles were identified through MEDLINE and LILACS data bases, using the keywords "suprarenal cortex", "skin", "massage", "infants", "glucocorticoid" and "circadian rhythm". Single articles published between 1990 and 2003 were considered, as well as outstanding ones prior to this period. Studies recognize that the hypothalamus, the pituitary and the adrenal gland are dynamic organs during fetal and neonatal development, and that stress responses are active at birth. Most of the studies reviewed, using tactile-kinesthetic stimulation, both in humans and animals, confirm skin's ability to metabolize, coordinate and organize external stimuli, attempting to maintain both

    2014-01-01

    Software reuse and integration has been described as the process of creating software systems from existing software rather than building software systems from scratch. Whereas reuse solely deals with the artifacts creation, integration focuses on how reusable artifacts interact with the already existing parts of the specified transformation. Currently, most reuse research focuses on creating and integrating adaptable components at development or at compile time. However, with the emergence of ubiquitous computing, reuse technologies that can support adaptation and reconfiguration of architectures and components at runtime are in demand. This edited book includes 15 high quality research papers written by experts in information reuse and integration to cover the most recent advances in the field. These papers are extended versions of the best papers which were presented at IEEE International Conference on Information Reuse and Integration and IEEE International Workshop on Formal Methods Integration, which wa...

    Full Text Available La seguridad es uno de los aspectos principales a considerar cuando se evalúa la calidad de servicio provista por un camino. Por lo tanto, la determinación precisa de la fricción superficial del pavimento adquiere suma importancia como parte de un plan de gestión de redes viales. Actualmente se emplean diversos equipos y procedimientos para medir la resistencia al deslizamiento en superficies de pavimento, tales como el Péndulo Británico, GripTester y SCRIM, entre otros. Con estos equipos se recopila información en terreno que se compara posteriormente respecto a valores umbrales que se consideran aceptables. Con el fin de asegurar una confiabilidad y nivel de calidad aceptables para esos resultados, se debe realizar un monitoreo constante a los procedimientos de medición, así como revisiones y calibración de los instrumentos. Este artículo propone una metodología general para el control de calidad en instrumentos y mediciones de resistencia al deslizamiento. Tal metodología ha sido diseñada usando listas de verificación y aplicando conceptos estadísticos de repetibilidad y reproducibilidad. La metodología fue aplicada para evaluar el nivel de calidad alcanzado por instrumentos y procedimientos de medición de resistencia al deslizamiento empleados en Chile, con buenos resultados. La calidad de los procedimientos de evaluación incluidos en dicha metodología también fue verificada, usando las técnicas de análisis estadísticos Seis-Sigma, lo que contribuyó significativamente a mejorar el sistema de control de calidad propuesto.Safety is one of the main issues that must be considered when evaluating the quality of service provided by a road.

En este artículo se propone un modelo de ecuaciones estructurales para explicar la influencia de la RSC y su integración en el sistema de gestión de la empresa, facilitada por la existencia de sistemas de gestión normalizados previos, y cómo influye dicha integración en la estrategia de la empresa y si esto tiene un reflejo en el performance económico de la empresa tecnológica. El estudio se llevó a cabo en empresas ubicadas en parques científicos y tecnológicos españoles. Los resultados del modelo revelan que existe una relación positiva, directa y estadísticamente significativas entre la integración de la RSC y la estrategia, por un lado, y la integración y el performance, por el otro. Asimismo se evidencia unas relaciones indirectas entre los sistemas de gestión normalizados previos a la implantación de la RSC y el performance y, por tanto, con implicaciones prácticas para la gestión de la RSC en empresas tecnológicas. || The importance of management systems for the integration of CSR in the company strategy is a vital resource that has been little studied in technology companies.

    Full Text Available El objetivo del presente artículo es ofrecer consideraciones acerca de la producción de agroenergía a partir de la biomasa en sistemas agroforestales integrados. En la actualidad a nivel global, marcado por un conjunto de peligros que amenazan la existencia de la especie humana, existe un reto principalmente en el contexto rural: ¿cómo hacer coexistir la agroenergía, la seguridad alimentaria y la protección del medio ambiente?, en presencia de cambios climáticos, degradación ambiental, crisis alimentarias y la creciente contradicción biocombustibles vs alimentos, generada por una insensata política para obtener agrocombustibles de primera generación a partir de grandes extensiones de monocultivos alimentarios, lo que es moralmente rechazable. También los biocombustibles son considerados como una alternativa ecológica a los combustibles fósiles, por su capacidad de reducción en la emisión de gases de efecto invernadero y por promover el desarrollo de comunidades rurales en los países del Sur; ello se potencia en los sistemas agroforestales integrados, en los que se pueden producir biocombustibles, tanto de primera como de segunda generación, sobre todo con la aplicación del concepto de biorrefinería que posibilita convertir la biomasa en múltiples productos, cuyo valor agregado total puede ser mayor que el generado por los combustibles fósiles. A este propósito contribuyen los proyectos internacionales, que promueven la producción integrada y sostenible de alimentos y energía en el contexto de sistemas agroforestales integrados, a escala local. Los autores consideran que la ejecución de proyectos y experiencias sobre agroenergía tiene el propósito principal de lograr la sostenibilidad energética y la seguridad alimentaria a escala local, en el medio rural, teniendo en cuenta la protección del ambiente.The objective of this paper is to offer considerations about agroenergy production from biomass in integrated

    Great problems are found by who need to get a power plant capable to mostly make possible the deriving food production of the fruits. The use of the electric energy of the plants and micron-plant is one of the main factors for the rise in the cost of the production. The use of alternative sources of energy sells at a loss a little this cost. Of this form, this project of integrated system of production of energy for agroindustry, supported for the CNPq, becomes advantageous all the investments that come to be made in this direction. The objective of the research is to develop a new synthesis of processes for use of vegetal biomass (wood) for production of the applied electric energy in the process of manufacture of jelly of fruits with co-production of activated coal. Our project of residual biomass produces energy from the wood saw pyrolysis and gasification. And also uses the substitution of the glucose found in the sugar for the pectin, proceeding from the rinds of fruits. Comparative results indicate that this substantiates (pectin) is sufficiently efficient in the control of the cholesterol level of the blood and also is very rich in the energy supply for the people who consume them. After carried through bibliographical research on the current state of the technology of the production of energy based on the vegetal biomass of firewood, processes of term conversion, reactor of activation and equipment, to leave of this had been developed engineering projects, with the use of the tool Super ProDesigner 4.9. Some simulations of processes of fast pyrolysis, gasification, separation of bio oil, generation of energy including system of integration of energy production as innovation of the considered work had been made. To leave of this, two scenes had been developed: one, the current process of production and the other, our innovation, being studied at great length the project of investment and costs, analysis of viability and cash flux using software Orcamento

    New design and strategies to manage wet weather floes in combined sewer systems, which main objective is to minimize environmental impacts on water bodies, require the treatment of large volumes of storm water. Wet weather flows introduced into combined sewer show dynamic-transient behavior both in terms of flow discharges and pollution. With traditional design strategies, large pollution peaks are spilled during rain events into water receiving bodies by combined sewer overflows (CSOs). Nowadays, CSOs have been reduced providing some storage capacity into the combined sewer systems (either in network, by means storm water tanks, or in WWTP). The stored storm water and its associated pollution should be treated. WWTP inflows during rainy events are conditioned by the local storm water management strategy. The WWTP can be overcome if it is managed using traditional dry weather strategies. In order to optimize the treatment performance and to assure that urban pollution do not reach aquatic environment, the WWTP must participate in the system in an integrated manner. This is a key element. This paper shows firstly the importance of CSO pollution and the development of new strategies for storm water management in combined sewer systems. Storm water tanks, located in the sewerage system, have been one of the most common solutions adopted but there are some experiences of wet weather flow management at the WWTP. All these strategies are revised in the paper. Once the role of the WWTP in the new combined sewer systems is known, the article presents a review about the problems generated by the hydraulic overloads and the large variations of the pollution characteristics on different stages of the water line. Special emphasis is made on the problems generated in secondary processes based on activated sludge. these problems are analysed in detail and some mitigation strategies are proposed.

O experimento foi iniciado em maio de 2001 em área pertencente à Fazenda do Espinilho, localizada no município de São Miguel das Missões - RS, em Latossolo Vermelho distroférrico que vinha sendo cultivado em plantio direto desde 1991. Os tratamentos constaram de intensidades de pastejo: 10, 20, 30 e 40 cm de altura do pasto e um tratamento sem pastejo, distribuídos num delineamento experimental de blocos ao acaso, com três repetições. Os teores de K disponível eram originalmente altos e assim se mantiveram ao longo do tempo, independentemente do tratamento de pastejo. Em todas as situações houve a formação de um gradiente decrescente de concentração de K a partir da superfície, sendo maior após pastagem que após soja. A ausência do pastejo, apesar de propiciar menor ciclagem de K, resultou em maiores teores do nutriente no solo, em relação às áreas com animais, especialmente aquelas intensamente pastejadas, devido às perdas causadas, provavelmente, pelas excretas.Potassium (K dynamics in integrated crop-livestock (ICL systems diverge from other tillage systems, because ICL systems are more complex and involve, apart from the cash crop management, the presence of animals.

    With the objective of simplifying the complex mesh of computing devices employed within nuclear power plants, modern technology and integration techniques are being used to form centralized (but backed up) databases and distributed processing and display networks. Benefits are immediate as a result of the integration and the use of standards. The use of a unique data acquisition and database subsystem optimizes the high costs of engineering, as this task is done only once for the life span of the system. This also contributes towards a uniform user interface and allows for graceful expansion and maintenance. This article features an integrated information system, Sistema Integral de Informacion de Proceso (SIIP). The development of this system enabled the Laguna Verde Nuclear Power plant to fully use the already existing universe of signals and its related engineering during all plant conditions, namely, start up, normal operation, transient analysis, and emergency operation. Integrated systems offer many advantages over segregated systems, and this experience should benefit similar development efforts in other electric power utilities, not only for nuclear but also for other types of generating plants

Additionally, the system has the capacity to expand in order to create a distributed monitoring and control system by using a CAN bus as a communication interface. It is also shown in this paper the implementation of the developed system in different plants.

    The Research and Development (R&D) project on “Theoretical and Methodological Approaches to Integrated System Validation of Control Rooms, 2014-2015”, in which the research activities described in this report are framed, has two main objectives: to develop the items for an usability methodology conceived as a part of the measurement framework for performance-based control room evaluation that the OECD Halden Reactor Project will test in the experiments planned for 2015; and the statistical analysis of the data generated in the experimental activities of the Halden Man-Machine Laboratory (HAMMLAB) facility, with previous usability questionnaires, in 2010 and 2011. In this report, the procedure designed to meet the first goal of the project is described, in particular, the process followed to identify the items related to information displays, one of the elements to be included in the usability questionnaire. Three phases are performed, in the first one, the approaches developed by the United States Nuclear Regulatory Commission, NRC, are reviewed and the models proposed by the nuclear energy industry and their technical support organizations, mainly, the United States Electric Power Research Institute, EPRI, are analyzed. In the remaining stages, general and specific guidelines for information displays, in particular, display pages, formats, elements and data quality and update rate recommendations are compared and criteria for the preliminary selection of the items that should be incorporated into the usability questionnaire are defined. This proposal will be reviewed and adapted by the Halden Reactor Project to the design of the specific experiments performed in HAMMLAB.

Em virtude da complexidade desse "sistema sem muros", que elimina as barreiras de acesso entre os diversos níveis de atenção, em resposta às necessidades de saúde nos âmbitos local e regional, julgamos oportuno compartilhar algumas "lições preliminares" aprendidas em experiências pessoais e na literatura sobre a integração de serviços, que nos parecem de interesse comum aos pesquisadores e gestores comprometidos com a sua implantação.The premise of this paper is that comprehensive health care is a major component in the investigation and evaluation of health services and systems, structured as inter-organizational health care networks articulating clinical, functional, normative, and systemic dimensions in their operationalization and based on the understanding that no organization combines all the necessary resources and capabilities to solve the health problems of a population with its various life cycles. Given the complex nature of this "system without walls", eliminating barriers to access in the various health care levels in response to local and regional health, we take this opportunity to share a few "preliminary lessons" from our experience and from the literature on integrated health services which may interest researchers and managers concerned with the implementation of such services.

    2003-01-01

    A management system is developed in order to reflect the needs of the business and to ensure that the objectives of the organization will be achieved. The process model and each individual process within the system then needs to identify the drives or requirements from external customers and stakeholders, regulations, and standards such as ISO and 50-C-Q. The processes are then developed to address these drivers. Developing the process in this way makes it fully integrated and capable of incorporating any new requirements. The International Standard (ISO 9000:2000) promotes the adoption of a process approach when developing, implementing and improving the effectiveness of a quality management system to enhance customer satisfaction by meeting customer requirements. The IAEA Code recognizes that the entire work is a process which can be planned, assessed and improved. For an organization to function effectively, numerous linked activities have to be identified and managed. By definition a process is an activity that using resources and taking into account all the constraints imposed executes the necessary operations which transform the inputs in outcomes. Running a system of processes within an organization, identification of the interaction between the processes and their management can be referred to as a 'process approach'. The advantage of such an approach is the ensuring of the ongoing control over the linkage between the individual processes composing the system as well as over their combination and interaction. Developing a management system implies: identification of the process which delivers Critical Success Factor (CSFs) of the business; identifying the support processes enabling the CSFs to be accomplished; identifying the processes that deliver the business fundamentals. An integrated management system should include all activities not only those related to Quality, Health and Safety. When developing an IMS it is necessary to identify all of the drivers

    The NET system integration procedure is the process by which the requirements of the various Tokamak machine design areas are brought together to form a compatible machine layout. Each design area produces requirements which generally allow components to be built at minimum cost and operate with minimum technical risk, and the final machine assembly should be achieved with minimum departure from these optimum designs. This is carried out in NET by allowing flexibility in the maintenance and access methods to the machine internal components which must be regularly replaced by remote handling, in segmentation of these internal components and in the number of toroidal field coils

    1999-01-01

    New turnkey data acquisition systems purchased from industry are being integrated into CERN's Technical Data Server. The short time available for system integration and the large amount of data per system require a standard and modular design. Four different integration layers have been defined in order to easily 'plug in' industrial systems. The first layer allows the integration of the equipment at the digital I/O port or fieldbus (Profibus-DP) level. A second layer permits the integration of PLCs (Siemens S5, S7 and Telemecanique); a third layer integrates equipment drivers. The fourth layer integrates turnkey mimic diagrams in the TCR operator console. The second and third layers use two new event-driven protocols based on TCP/IP. Using this structure, new systems are integrated in the data transmission chain, the layer at which they are integrated depending only on their integration capabilities.

    The Radon Integral Measurement System (SMIR) is a device designed specially to detect, to count and to store the data of the acquisition of alpha particles emitted by Radon-222 coming from the underground. The system includes a detection chamber, a radiation detector, a digital system with bateries backup and an auxiliary photovoltaic cell. A personal computer fixes the mode in which the system works, transmitting the commands to the system by the serial port. The heart of the system is a microprocesor working with interrupts by hardware. Every external device to the microprocessor sends his own interrupt request and the microprocessor handles the interrupts with a defined priority. The system uses a real time clock, compatible with the microprocessor, to take care of the real timing and date of the acquisition. A non volatile RAM is used to store data of two bytes every 15 minutes along 41 days as a maximum. After the setting up to the system by the computer, it can operate in stand alone way for up 41 days in the working place without the lose of any data. If the memory is full the next data will be written in the first locations of the memory. The memory is divided in pages corresponding every one of this to a different day of the acquisition. The counting time for every acquisition can be programmed by the user from 15 minutes to 65535 minutes but it is recommended to use a small time not to reach the limit of 65535 counts in every acquisition period. We can take information of the system without affecting the acquisition process in the field by using a lap top computer, then the information can be stored in a file. There is a program in the computer that can show the information in a table of values or in a bar graph. (Author)

  9. From the model of El Sistema in Venezuela to current applications: learning and integration through collective music education.

    2012-04-01

    Over the last years, El Sistema--the Venezuelan project started in 1975 and now acknowledged worldwide as the most significant example of collective music education--has inspired a profusion of remarkable initiatives on all continents. From the original impulse by founder José Antonio Abreu, strong social principles of integration are combined with specific musical approaches to achieve individual empowerment as a large-scale alternative to endemic juvenile crime, counteracting the risk factors of social unease, serving as a stimulating example toward emancipation, and providing professional opportunities to the talented. Such a network, in turn, proves to be a powerful instrument of cultural progress: the tenets of "Sistema" become shared values able to foster development, reaching into issues of disability and rehabilitation. This paper presents continuities and contrasts in various ramifications of such a successful trend and outlines perspectives for further impact of this powerful transformational agent. © 2012 New York Academy of Sciences.

    The pumping systems provide about 20 to 25 percent of energy which is necessary worldwide: it is fruitful to understand how to use electric power efficiently, to achieve the reduction regarding expenses a pumping system implies.It is essential to possess a better knowledge about the pumping system and its applications, in order to be able to use energy responsibly. If people do not how to operate this kind of systems properly, they will use inadequate equipment that will cause an energy waste. In addition it is important to know: alternative methods to meet variable demands, an adapted system to pump water requirements in order to ensure the pump work in its pumping point, and the life cycle system cost for the energy saving in the long term. [Spanish] En promedio del 20 al 25% de la energia necesaria en el mundo proviene de los sistemas de bombeo, por tal razon es importante saber como utilizar la energia electrica con eficiencia para asi lograr reducir los gastos que este tipo de sistemas implican. Para poder hacer un buen uso de la energia, es necesario que se tenga un conocimiento mayor del sistema de bombeo y aplicacion, ya que la ignorancia sobre esto exige el uso de aparatos que contribuyen al desperdicio de la energia; por otro lado tambien es esencial conocer metodos alternos para demandas variables, tener un sistema que se adapte a las necesidades de bombeo del agua para asegurarse de que cada bomba trabaje cerca de su punto de bombeo y finalmente conocer el costo del ciclo de vida del sistema para el ahorro de energia a largo plazo.

    The development and integration of hybrid systems of electrical generation (SHGE) of small capacity: The intention of these developments is its implementation in isolated or far away communities from conventional electric networks, that contribute in the own productive processes of these towns. As part of these work a system of control for their hybrid system wind-photovoltaic- internal combustion machine was developed that operates nowadays in a system installed in Pachuca, Hidalgo, Mexico. However, in the two past years, the GENC has worked, altogether with the Management of Control and Instrumentation of the Instituto de Investigaciones Electricas (IIE) and the Centro Nacional de Investigacion y Desarrollo Tecnologico (CENIDET) (National Center of Research and Technological Development), to incorporate an intelligent control technique in the regulation of the hybrid systems of wind-photovoltaic-machine of internal combustion type. Lemos de Pereira rises that the main problems of the present technology of the SHGE are related to the control and supervision of the power systems. The system that is in charge of the actions of load control and dispatch is denominated supervisory control. This controller supervises the operation of all the components, regulates the entry or exiting of operation of the generation systems, as well as the loads.

    Full Text Available The paper examines systems integration and its main levels at higher levels of control. At present, the systems integration is one of the main aspects participating in the consolidation processes and financial flows of a company. Systems Integration is a complicated emotionconsuming process and it is often a problem to choose the right approach and level of integration. The research focused on four levels of integration, while each of them is characterized by specific conditions. At each level, there is a summary of recommendations and practical experience. The paper also discusses systems integration between the information and MES levels. The main part includes user-level integration where we describe an example of such integration. Finally, we list recommendations and also possible predictions of the systems integration as one of the important factors in the future.

    During the 80's, companies started to be concerned with more than their production processes. Due to the demands for products and services quality, in 1987, ISO 9000 (International Standards Organization) was established. Ten years later, ISO 14000 was established, regarding environmental management system, and in the same period BS 8800 (British Standards) and OHSAS 18001 (Occupational Health and Safety Assessment Series) were also published, regarding occupational health and safety in the working environment. With the increasing demands for companies that participate with the country's economical and social development, SA 8000 was elaborated. In the present days, companies that do not incorporate these factors (quality, environment, occupational health, safety, and social responsibility), has its markets diminished. For several countries, especially European countries, environmental and social aspects are essential for companies and products to gain entry into their markets. The implementation of such systems therefore aids companies to manage their aspects, leading to continuous process improval and the opening of new markets. A company's success depends more of the demands of national and international agencies (financing or licensing agencies, for example). Financing agencies have to assure themselves that they are investing in environmentally and socially friendly projects. Licensing agencies require that specific projects take place with the smallest possible environmental impact. The existence of a management system in the company that incorporates environmental management facilitates the licensing process, as well as financing by multilateral national and international agencies. Certification therefore acts as an important tool to help companies as well as financing and licensing agencies, demonstrating the company's global commitment with such aspects. (author)

    The United States Department of Energy elaborates the compelling need for a commercialized competitively priced electric traction drive system to proliferate the acceptance of HEVs, PHEVs, and FCVs in the market. The desired end result is a technically and commercially verified integrated ETS (Electric Traction System) product design that can be manufactured and distributed through a broad network of competitive suppliers to all auto manufacturers. The objectives of this FCVT program are to develop advanced technologies for an integrated ETS capable of 55kW peak power for 18 seconds and 30kW of continuous power. Additionally, to accommodate a variety of automotive platforms the ETS design should be scalable to 120kW peak power for 18 seconds and 65kW of continuous power. The ETS (exclusive of the DC/DC Converter) is to cost no more than $660 (55kW at $12/kW) to produce in quantities of 100,000 units per year, should have a total weight less than 46kg, and have a volume less than 16 liters. The cost target for the optional Bi-Directional DC/DC Converter is $375. The goal is to achieve these targets with the use of engine coolant at a nominal temperature of 105C. The system efficiency should exceed 90% at 20% of rated torque over 10% to 100% of maximum speed. The nominal operating system voltage is to be 325V, with consideration for higher voltages. This project investigated a wide range of technologies, including ETS topologies, components, and interconnects. Each technology and its validity for automotive use were verified and then these technologies were integrated into a high temperature ETS design that would support a wide variety of applications (fuel cell, hybrids, electrics, and plug-ins). This ETS met all the DOE 2010 objectives of cost, weight, volume and efficiency, and the specific power and power density 2015 objectives. Additionally a bi-directional converter was developed that provides charging and electric power take-off which is the first step

    2014-01-01

    Maximisation of the ratio of normal tissue preservation and tumour cell reduction is the main concept of radiotherapy alone or combined with chemo-, immuno- or biologically targeted therapy. The foremost parameter influencing this ratio is radiation sensitivity and its modulation towards a more efficient killing of tumour cells and a better preservation of normal tissue at the same time is the overall aim of modern therapy schemas. Nevertheless, this requires a deep understanding of the molecular mechanisms of radiation sensitivity in order to identify its key players as potential therapeutic targets. Moreover, the success of conventional approaches that tried to statistically associate altered radiation sensitivity with any molecular phenotype such as gene expression proofed to be somewhat limited since the number of clinically used targets is rather sparse. However, currently a paradigm shift is taking place from pure frequentistic association analysis to the rather holistic systems biology approach that seeks to mathematically model the system to be investigated and to allow the prediction of an altered phenotype as the function of one single or a signature of biomarkers. Integrative systems biology also considers the data from different molecular levels such as the genome, transcriptome or proteome in order to partially or fully comprehend the causal chain of molecular mechanisms. An example for the application of this concept currently carried out at the Clinical Cooperation Group “Personalized Radiotherapy in Head and Neck Cancer” of the Helmholtz-Zentrum München and the LMU Munich is described. This review article strives for providing a compact overview on the state of the art of systems biology, its actual challenges, potential applications, chances and limitations in radiation oncology research working towards improved personalised therapy concepts using this relatively new methodology

The results as far as reliability indexes compared with the other methods were very satisfactory and promising as far as required CPU time and memory for larger systems. [Spanish] En esta tesis se ataca el problema de la Evaluacion de la Confiabilidad de los Sistemas de Transmision de Energia Electrica para fines de su planeacion integral. Una vez descrito el problema se presentan los indices que miden la confiabilidad de los sistemas electricos de potencia. Despues se describen los metodos para evaluar las redes de transmision, como el de Enumeracion de Contingencias, el Monte Carlo, el de Markov y los metodos para sistemas complejos como el de Cortes Minimos. Este ultimo se desarrolla ampliamente por las ventajas que presenta su aplicacion en la planeacion de redes grandes y complejas. El metodo de cortes minimos consta de dos grandes pasos: Determinar los cortes minimos para los puntos de carga y calcular los indices de confiabilidad en base a los cortes minimos. Los algoritmos convencionales para la determinacion de cortes minimos consideran un problema por cada punto de carga en forma independiente pasando por una determinacion de caminos minimos. En este tipo de algoritmos el tiempo de CPU y el espacio en memoria requeridos crecen exponencialmente para el caso de sistemas de transmision grandes, lo que representa una fuerte restriccion para su aplicacion. Para resolver este problema se establecio una metodologia en la que se modela el sistema por medio de un grafo y se determinan los cortes minimos con un algoritmo basado en la construccion de ciclos en el grafo dual. Con estos cortes se evalua la conexidad y capacidad de la red, obteniendose los indices de confiabilidad para cada bus y para el sistema. Estos indices se calculan con la representacion equivalente para

  19. Robust control decentralized by sliding ways of electrical of power multi-machines systems; Control robusto descentralizado por modos deslizantes de sistemas electricos de potencia multimaquinas

    Energy Technology Data Exchange (ETDEWEB)

    Huerta Avila, Hector

    2008-09-15

    This work deals with the problem of robust decentralized control of multimachine electric power systems. These systems are subject to different perturbations, such as short circuits, connection and/or disconnection of loads, lines generators, mechanical torque variations, etc. Then, it is necessary controllers which guarantee robustness under those perturbations to provide electrical energy to the loads with admissible stability margins. Moreover, the controller must be robust under parametric variations due to model uncertainties, and other physical reasons. The electrical power systems are modeled as complex great scale nonlinear systems. Then, the controller design is a challenging problem. Thus, the decentralized control schemes enable to avoid these problems. This work proposes three novel robust nonlinear techniques. The first one is based on the block control and integral sliding modes. The second obtains a sliding manifold from the Hamiltonian model of a nonlinear system to use this manifold in the integral sliding modes. The third technique enables to apply the sliding mode technique to a nonlinear block controllable system, by using Lyapunov function in each block. Then, four control schemes for electric power systems are designed. The four control schemes are robust under the perturbations of electric power systems mentioned above. The controllers proposed can be implemented in any electric power system with n generators, m lines and k loads. [Spanish] Este trabajo esta dedicado al diseno de esquemas de control robustos descentralizados que sean capaces de responder satisfactoriamente en sistemas electricos de potencia multimaquinas. Estos sistemas estan sujetos a perturbaciones de diferentes tipos, como cortos circuitos, entrada y salida de lineas de cargas o de generadores. Es evidente la necesidad de controladores que puedan rechazar estas perturbaciones para proveer energia de calidad y sin interrupciones a todos los usuarios conectados a la red

    A complete 100-Mc counting system is described for use in experiments with accelerators. Current-switching logic, using both transistors and germanium tunnel diodes, is used for all high-speed logic. All critical circuits have a rise-time and time-jitter of 2 ns or less. The logical elements are a pulse-height limiter, a discriminator, a multichannel coincidence circuit, a four-fold fanout, and a scale of 8. The fanout enables a limiter or discriminator output to drive any combination of four elements. Each element is a separate plug-in module. Elements are interconnected by a 50-{Omega} cable with at least one termination. Most module inputs and outputs are compatible so that, for example, a discriminator can either drive or be driven from a coincidence circuit by switching cables. To insure reliable high-speed operation and good time and temperature stability the transistors were operated at unity change-gain either in a current-switching mode or in a linear mode as a distributed amplifier. Each tunnel diode provided an additional switching charge-gain of from 2 to 5 with the same stability and bandpass as the transistors. Each module was designed for operation up to a continuous counting rate of 100 megapulses per second. High system duty cycles were made possible by DC interconnections and by double-delay-line clipping for recovery between pulses. No loss in system performance is anticipated for counting rates to 50 Mc. The basic discriminator has a sensitivity adjustable from 2 to 10 mA with a DC-Coupled output of 10 mA at ground potential. Output rise and fall times are 1 ns; pulse width is set by delay cable; maximum output duty cycle is 50% for 95% input recovery. Time jitter from threshold firing to three times that level is 2 ns or less. A more sophisticated version has 10 times the sensitivity. It has a distributed amplifier and a switching chain of two tunnel diodes. Output specifications are the same. Other logic systems for discriminators will also be

    1998-07-01

    In this thesis project a system for the quantification and study of the harmonics content in electrical systems was developed. The study is focused to signals of feeding current to a Long Arc furnace. The system developed for the quantification of the harmonics content is formed by the following parts: (a) Data acquisition system: The application of a data acquisition system makes possible for us to take samples from an analogous voltage signal. The acquired samples that represent an analogous signal, can later be processed in a digital computer. The data acquisition system is constituted by: An IBM-PC microcomputer, a digitalization card of analogous signals, and programs to conduct signals sampling (b) Digital processing of the acquired signals: With the purpose of obtaining the harmonic content, the Fast Fourier Transform method was used. The analysis by means of the Fast Fourier Transform allows us to obtain the signals spectra in the frequency dominion. Through the analysis by means of the Fast Fourier Transform a substantial diminution of the calculation time of the coefficients corresponding to the harmonics is obtained, this compared with the method of Discreet Fourier Series. (c) Analysis of obtained results: Several line current and capacitors measurements of the feeding system signals of an arc furnace were made. For each measurement made the magnitude and the phase for each harmonic was obtained. Of the assembly of coefficient magnitudes and phases, the average value and its standard deviation were calculated. Graphs of the magnitude variation with time and phase of each harmonic are shown. Also, graphs of the waveform of the signal in analysis are obtained, bar charts of the average spectral content and a report of the standard deviation of the magnitude and the phase for each harmonica, is obtained. Results of a simulation of the electrical system in analysis are included and the results are compared. [Spanish] En este proyecto de tesis se desarrollo

    Due to the characteristics of flow, gas can separate from oil in the pipelines and risers that link subsea manifolds to production offshore platforms, forming liquid and gas slugs in the production separator. Liquid slugs can cause overflow in the separators. Gas slugs can cause burning in the flare due to the limitation in the turbo-compressors acceleration. In both cases the consequences are loss of production or shut-downs. This paper presents a Slug Control System designed to attenuate severe gas and liquid flow variations. The system consist of a control valve installed in the separator inlet, transmitters, a controller, control algorithm and a monitoring station. This system is operating since October 2003 in a production offshore platform, in Campus Basin, Brazil, with excellent results, reducing the gas burning in 45% without oil production loss. (author)

    2005-01-01

    A new class of discrete dynamical systems is introduced via a duality relation for discrete dynamical systems with a number of explicitly known integrals. The dual equation can be defined via the difference of an arbitrary linear combination of integrals and its upshifted version. We give an example of an integrable mapping with two parameters and four integrals leading to a (four-dimensional) dual mapping with four parameters and two integrals. We also consider a more general class of higher-dimensional mappings arising via a travelling-wave reduction from the (integrable) MKdV partial-difference equation. By differencing the trace of the monodromy matrix we obtain a class of novel dual mappings which is shown to be integrable as level-set-dependent versions of the original ones

    Full Text Available En este trabajo se describe el sistema de salud de Costa Rica, que presta servicios de salud, agua y saneamiento. El componente de servicios de salud incluye un sector público y uno privado. El sector público está dominado por la Caja Costarricense de Seguro Social (CCSS, institución autónoma encargada del financiamiento, compra y prestación de la mayoría de los servicios personales. La CCSS se financia con contribuciones de los afiliados, los empleadores y el Estado, y administra tres regímenes: el seguro de enfermedad y maternidad, el seguro de invalidez, vejez y muerte, y el régimen no contributivo. La CCSS presta servicios en sus propias instalaciones o contrata prestadores del sector privado con los que establece contratos denominados "compromisos de gestión". El sector privado comprende una amplia red de prestadores que ofrecen servicios ambulatorios y de especialidad con fines lucrativos. Estos servicios se financian sobre todo con pagos de bolsillo, pero también con primas de seguros privados. El Ministerio de Salud es el rector del sistema y como tal cumple con funciones de dirección política, regulación sanitaria, direccionamiento de la investigación y desarrollo tecnológico. Dentro de las innovaciones relativamente recientes que se han implantado en Costa Rica destacan la implantación de los equipos básicos de atención integral de salud (EBAIS, la desconcentración de los hospitales y clínicas públicos, la introducción de los acuerdos de gestión y la creación de las Juntas de Salud.This paper describes the Costa Rican health system which provides health, water and sanitation services.

    Igneous-sedimentary petroleum systems are mixed systems in which one or more essential elements or processes are related to magmatic events. Many examples worldwide are presented to show the importance of igneous rocks in the exploratory activities, as well as in the petroleum occurrence. Volcanic ash layers are of great importance in stratigraphic correlation and elucidation of structures, particularly when they occur in thick nonfossiliferous strata. They are also good indicators of turbidite deposition where turbidity currents are related to earthquakes generated by magmatic events. Unconventional reservoirs can be created by volcanic eruptions or intrusions, crystallization, reworking, and fracturing. Unaltered igneous rocks can seal vertically and laterally conventional reservoirs due to its excellent cap capacity. Abnormal thermal effect of igneous rocks can compensate the lack of overburden in shallow basins. Structural or combined traps can be formed due to intrusions, such as folded, faulted, and unconformity traps. Porosity can be either primary or secondary, or both. Primary porosity mainly consists of cavities produced by gas volatilization during eruption and cooling. Secondary porosity refers to those pores that result from hydrothermal alteration, recrystallization, and dissolution by groundwater, and tectonic stress. It includes intercrystalline pores formed by crystallization of various secondary minerals, dissolution pores, and tectonic fractures. New technologies of petroleum development and production are encouraging to search for oil and gas within igneous rocks, and new discoveries are expected. (author)

    The speed and magnitude of tropical pastures expansion in Brazil are related to the availability of quality seeds. This research aimed to evaluate the physiological quality of seeds of two Brachiaria species submitted to germination and viability tests and also estimate, for both species, the fresh and dry mass yield, under different irrigated crop-livestock integration systems. For field analysis, the experimental design was a randomized complete block, in subplots, with four intercrops in the plot (Brachiaria brizantha cv. Marandu and Brachiaria ruziziensis simultaneously established with corn and nitrogen fertilization coverage, and four forage cutting times, in the winter/spring season, in subplots, with four replications. In the laboratory, the experimental design was completely randomized, with four replications per treatment/test. The germination and viability tests indicated that B. brizantha seeds showed higher physiological quality, when compared with B. ruziziensis, while the tetrazolium test and germinated seedlings characteristics were similar. The B. ruziziensis, simultaneously intercropped with corn, was the less viable intercrop, due to the lower fresh and dry mass yield and litter deposition on the soil surface. In general, the pasture formation for the second season cultivation, intercropped with corn, was an excellent alternative for crop-livestock integration under a no-tillage system.

    An Environmental Management System was implemented in ANAV in 1999, including the two nuclear sites of the Asco and Vandellos II nuclear power plants. This implementation entailed formulation of the ANAV Environmental Policy, preparation of an Environmental Management Plan (PLAGMA) supported by the Environmental Aspects Manuals (MASMA) of each site and their operating procedures, modification of the organizational structure to create the Environment Unit, in charge of implementing the SIGEMA, and the Environment Committee, the governing body that reviews the results obtained and environmental goals to be achieved, and direct involvement of all the different ANAV organization in continuous improvement of the SIGEMA implementation. Special attention is paid to evolution of the environmental indicators, to communication and specific training in environmental issues, and to waste management and the different programs for increasing waste recycling and assessment, as well as to minimization programs. The article details the different approaches used to improve the environmental results in these last five years, which have allowed ANAV to maintain the ISO-14001 Certification since 1999. (Author)

    Smith, D.J.

    1991-01-01

    This paper reports that instrument manufacturers must develop standard network interfaces to pull together interrelated systems such as automatic start-up, optimization programs, and online diagnostic systems. In the past individual control system manufacturers have developed their own data highways with proprietary hardware and software designs. In the future, electric utilities will require that future systems, irrespective of manufacturer, should be able to communicate with each other. Until now the manufactures of control systems have not agreed on the standard high-speed data highway system. Currently, the Electric Power Research Institute (EPRI), in conjunction with several electric utilities and equipment manufactures, is working on developing a standard protocol for communicating between various manufacturers' control systems. According to N. Michael of Sargent and Lundy, future control room designs will require that more of the control and display functions be accessible from the control room through CRTs. There will be less emphasis on traditional hard-wired control panels

    Donnelly, J.

    1982-09-01

    Twenty years of experience have shown that the early choices of heavy water as moderator and natural uranium as fuel imposed a discipline on CANDU design that has led to outstanding performance. The integrated structure of the industry in Canada, incorporating development, design, supply, manufacturing, and operation functions, has reinforced this performance and has provided a basis on which to continue development in the future. These same fundamental characteristics of the CANDU program open up propsects for further improvements in economy and resource utilization through increased reactor size and the development of the thorium fuel cycle

    In this article is presented a solar refrigeration system that integrates the more recent and important technological advances of the training solar systems (SCS) and of the advanced absorption units. An analysis and evaluation is made of the energy behavior of the absorption system with heat exchanger absorber-generator (GAX), air cooled and assisted by a hybrid power plant natural gas-solar. Given the characteristic of high not-linearity of the resulting system of occupations, the proposed methodology contemplates a calculation sequence for the external currents and an iterative procedure for the internal currents. The unit was designed with a capacity of 10.6 kw (3 tons.) of cooling and uses ammonia-water as working fluid. Giving priority to internal energy integration, an arrangement of the GAX cycle is proposed, that allows 19% of solar contribution at full load, being able to be greater at partial loads. In spite of using as cooling means air at 40 Celsius degrees with a relative humidity of 24%, a COP of 0.86 in the cooling mode was obtained and 1.86 in the heating mode, with an internal energy integration of 1013 kJ/min, 37% more of the energy that is supplied in the generator. The massic flow rates of the GAX cycle were compared with those of a basic cycle, resulting 73% and 62% lower for the circulation rate and for the flow rate, respectively.

    2013-01-01

    In this paper, we focus on the construction of new (1+1)-dimensional discrete integrable systems according to a subalgebra of loop algebra à 1 . By designing two new (1+1)-dimensional discrete spectral problems, two new discrete integrable systems are obtained, namely, a 2-field lattice hierarchy and a 3-field lattice hierarchy. When deriving the two new discrete integrable systems, we find the generalized relativistic Toda lattice hierarchy and the generalized modified Toda lattice hierarchy. Moreover, we also obtain the Hamiltonian structures of the two lattice hierarchies by means of the discrete trace identity

    On any advanced integrated circuit or 'system-on-chip' there is a need for security. In many applications the actual implementation has become the weakest link in security rather than the algorithms or protocols. The purpose of the book is to give the integrated circuits and systems designer an insight into the basics of security and cryptography from the implementation point of view. As a designer of integrated circuits and systems it is important to know both the state-of-the-art attacks as well as the countermeasures. Optimizing for security is different from optimizations for speed, area,

    Children (aged 9-12) training in an El Sistema-inspired program (OrKidstra) and a matched comparison group participated in an auditory Go/No-Go task while event-related potentials (ERPs) were recorded. Entire-sweep waveform patterns correlated with known ERP peaks associated with executive and other cognitive functions and indicated that the spread of neural activity in the initial 250 ms of executive attention processing (pre-P300) showed higher level of topographical overlap in OrKidstra children. In these children, late potentials (post-P300) concurrent with response control were more widely distributed and temporally coordinated. Intensive ensemble music training, we suggest, may be associated with neuroplastic changes facilitating integration of neural information.

Furthermore, such methodologies provide guidelines for treating requirements after being obtained. However, they do not propose tools such as a model of requirements for obtaining them. This paper is the result of a research project which objective is to propose engineering of requirements methodology for embedded systems analysis. The model of proposed requirements and its use are illustrated through an application case consisting on obtaining requirements for a movement sensing system, embedded in a home alarm system.

    ROLE7 is intended as a complementary addition to the HL7 Standard and not as an alternative standard. Attempt should be made to mould data elements which are specific to radiation therapy with existing HL7 elements. This can be accomplished by introducing additional values to some element's table-of-options. Those elements which might be specific to radiation therapy could from new segments to be added to the Ancillary Data Reporting set. In order to accomplish ROLE7, consensus groups need be formed to identify the various functions related to radiation oncology that might motivate information exchange. For each of these functions, the specific data elements and their format must be identified. HL7 is organized with a number of applications which communicate asynchronously. Implementation of ROLE7 would allow uniform access to information across vendors and functions. It would provide improved flexibility in system selection. It would allow a more flexible and affordable upgrade path as systems in radiation oncology improve. (author). 5 refs

    An integral communication and spectral analysis system (SICADE) was developed and implemented to satisfy the need to optimize and automate the measurement system used in Atucha I nuclear power plant for the activity in the primary loop`s water extracted by the TV system. The importance of these measurements is based on the fact that from the spectrometric analysis of the samples extracted, the Iodines-GN and Iodines-Iodines relations, which allow to detect the presence of deficient fuel elements, are calculated. The system developed is based on two modules integrated in a unique set commanded by the operators through the screen dialogue. (Author).

Los diagnósticos elaborados mediante SIRD fueron válidos, pues al seguir su recomendación se observó respuesta tanto en la composición interna de la planta como en la producción de café. El calcio, según el enfoque SIRD, se mostró como un elemento potencialmente limitante de la producción en la zona donde se analizó la validez del enfoque. La suma en valor absoluto de los indicadores SIRD, llamados Indice de Balance Nutricional, presentó correlación negativa y altamente significativa para los análisis foliares correspondientes a los meses de mayo.Diagnosis and Recommendation Integrated Systems (DRIS norms were developed for the interpretation of N, P, K, Ca, Mg, Mn, Fe and B contents of coffee (Coffea arabica L. leaves, obtained from a N-P-K factorial experiment at two different locations of the Colombian Coffee Zone.

    Full Text Available The Diagnosis and Recommendation Integrated System (DRIS allows the interpretation of results of leaf analysis through relationships among nutrients, instead of the absolute and isolated concentration of each one, as it is used by the criterion of sufficiency range. The objective was to evaluate three procedures of calculation of DRIS indices, and to verify the efficiency of DRIS as interpretation method for the results of Brachiaria decumbens (Signal grass. The study was developed with the results of six experiments carried out in a greenhouse at Piracicaba, SP, with nutrient solution. Concentrations of N, P, K, Ca, Mg, S, Cu, Fe, Mn, and Zn were used in the samples of recently expanded leaf laminae of the grass. The validation of the DRIS method used results from an experiment with nitrogen and sulfur rates applied to the same grass from the Mundo Novo farm, Brotas, SP. DRIS indices were calculated according to two criteria to choose the ratio order of nutrients (F value and R value and three ways to calculate the nutrient functions (methods of Beaufils, Jones, and Elwali & Gascho. Nutritional Balance Index (NBI, calculated according to the generated norms, presented negative and significant correlation coefficients with the productivity in the combinations of methods tested and DRIS methods proposed by Beaufils, Jones and Elwali & Gascho were efficient in detecting concentrations that show nutrients deficiency or excess.O Sistema Integrado de Diagnose e Recomendação (DRIS permite a interpretação dos resultados de análise foliar, utilizando relações entre nutrientes, ao invés da concentração absoluta e isolada de cada um deles, utilizada pelo critério de faixa de suficiência.

    The Daniel K. Inouye Solar Telescope (DKIST) Observatory is under construction at Haleakalā, Maui, Hawai'i. When complete, the DKIST will be the largest solar telescope in the world. The Facility Management System (FMS) is a subsystem of the high-level Facility Control System (FCS) and directly controls the Facility Thermal System (FTS). The FMS receives operational mode information from the FCS while making process data available to the FCS and includes hardware and software to integrate and control all aspects of the FTS including the Carousel Cooling System, the Telescope Chamber Environmental Control Systems, and the Temperature Monitoring System. In addition it will integrate the Power Energy Management System and several service systems such as heating, ventilation, and air conditioning (HVAC), the Domestic Water Distribution System, and the Vacuum System. All of these subsystems must operate in coordination to provide the best possible observing conditions and overall building management. Further, the FMS must actively react to varying weather conditions and observational requirements. The physical impact of the facility must not interfere with neighboring installations while operating in a very environmentally and culturally sensitive area. The FMS system will be comprised of five Programmable Automation Controllers (PACs). We present a pre-build overview of the functional plan to integrate all of the FMS subsystems.

    The drying of products -meaning the extraction of water or excess humidity down to adequate levels for its conservation and final presentation- demands a large amount of energy, mainly from fuels of fossil origin. Nevertheless, from the standpoint of the energy efficiency, the burning of fuels at very high temperature for using them at a very low temperature, represents an astonishing energy waste, which can be clearly established by means of an energy and exergy balance of these drying installations. In this study the methodology for the energy analysis for industrial drying systems is presented and it is applied to different practical cases. The efficiency of the entire system is evaluated and the losses for each concept, in order to obtain the potential energy saving. [Espanol] El secado de productos, entendido como la extraccion de agua o humedad en exceso, hasta niveles adecuados para su conservacion o presentacion final, demanda una gran cantidad de energeticos, principalmente de origen fosil.

En el presente estudio se presenta la metodologia de analisis energetico de sistemas industriales de secado y se aplica a distintos casos practicos. Se evalua la eficiencia total del sistema y las perdidas por cada concepto con la finalidad de obtener los potenciales de ahorro de energia.

    The nozzles used in high voltage electrical equipment, such as power transformers and circuit breakers, constitute the elements that present greater fault risk. On the other hand, the faults in the nozzles cause, in most of the cases catastrophic damages, that expose to risk the maintenance personnel of the plant and the peripheral equipment. With the purpose of contributing with on-line monitoring techniques that indicate the nozzles condition and allow to anticipate their possible fault, the Instituto de Investigaciones Electricas (IIE) performed for the laboratory of tests of equipment and materials (LAPEM) of Comision Federal de Electricidad (CFE), a project for the development of a system for the measurement of capacitive currents in these equipments. This system allows to determine the variation in capacitance and dielectric losses, and to determine the presence of internal partial discharges in nozzles of 115, 230 and 400 kV. With this information it is possible to determine the condition of the internal isolation of the nozzles and retire them from service before deterioration takes place that puts in danger the integrity of the equipment. The management of electrical equipment of the Instituto de Investigaciones Electricas developed for LAPEM a system that measures capacitive currents of power transformer nozzles. This system was designed with the purpose of installing it in a transformer of a 400 kV machine, in the fossil power station of Tula, Hidalgo, of the Comision Federal de Electricidad.

    In resent years cost reduction has been a key issue in the petroleum industry. Several findings are not economically attractive at the current cost level, and for this and other reasons some of the major oil companies require the suppliers to have implemented a cost reduction programme to prequalify for projects. The present paper addresses cost reduction through system design and integration in both product development and working methods. This is to be obtained by the combination of contracts by reducing unnecessary coordination and allow re-use of proven interface designs, improve subsystem integration by ''top down'' system design, and improve communication and exchange of experience. 3 figs

    Full Text Available Actualmente los consumidores no son pasivos, están altamente conectados y vinculados con las empresas. Por ello, algunas empresas aprovechan estas características para innovar productos a partir de los aportes de clientes. La co-creación como modelo colaborativo para la innovación se caracteriza por estar dividida en etapas relacionadas entre sí, con el fin de capturar apropiadamente los aportes de los clientes. La capacidad de valorar y clasificar los aportes de los agentes que participan en este proceso colaborativo es una tarea de crucial importancia para las organizaciones. El presente artículo propone un sistema difuso que permite valorar los aportes de los agentes que participan en forma colaborativa en la co-creación de productos y servicios.Now the customers are not passive, they are highly networked and connected with companies. Some companies take advantage of these features to innovate products from customer contributions. Co-creation like collaborative model to the innovation is characterized from being divided into interrelated stages in order to capture client's contributions in an appropriate way. The ability to assess and rank the contributions of the actors involved in this collaborative process is a crucial organizations task. The present paper proposes a fuzzy system that allows valuation for agent's contributions that participate in a collaborative way in products and services co-creation.

    Full Text Available Los colgajos pediculados pueden sufrir edema y congestión debido a que su drenaje a trevés del sistema venoso superfical es imposible y el flujo hacia el sistema profundo a nivel del pedículo es precario. Esta situación suele evolucionar hacia la necrosis parcial o la pérdida total del colgajo en pocas horas. La apertura del sistema venoso superficial permite el drenaje adecuado de los tejidos transferidos y evita estas complicaciones. Este artículo analiza el papel de las anastomosis microquirúrgicas en el sistema venoso superficial de los colgajos pediculados. Esta técnica permite comunicar el sistema venoso superfical de los tejidos transferidos con el sistema venoso superficial del territorio que rodea al defecto. Presentamos los resultados obtenidos con esta técnica en colgajos de perforante en hélice, colgajos miocutáneos, colgajos neurocutáneos y colgajos fasciograsos volteados.The pedicled flaps can suffer edema and congestion due to the impossibility of drainage toward the superficial venous system and the precarious flow via the deep system at the level of the pedicle. The evolution of this situation is usually partial necrosis or total loss of the flap in a few hours. The opening of the venous superficial system achieves an appropriate drainage of the transfered tissues and avoids these complications. In this article we analyze the role of the microsurgical anastomosis at the level of the superficial venous system of pedicled flaps. This technique allows to communicate the superficial venous system of the transfered tissues with the superficial venous system of the territory around the defect. We report the results with this method in propeller perforator flaps, miocutaneous flaps, neurocutaneous flaps and adipofascial turn over flaps.

    The multiloop integral system test (MIST) was part of a multiphase program started in 1983 to address small-break loss-of-coolant accidents (SBLOCAs) specific to Babcock and Wilcox-designed plants. MIST was sponsored by the US Nuclear Regulatory Commission, the Babcock and Wilcox Owners Group, the Electric Power Research Institute, and Babcock and Wilcox. The unique features of the Babcock and Wilcox design, specifically the hot leg U-bends and steam generators, prevented the use of existing integral system data or existing integral system facilities to address the thermal-hydraulic SBLOCA questions. MIST and two other supporting facilities were specifically designed and constructed for this program, and an existing facility -- the once-through integral system (OTIS) -- was also used. Data from MIST and the other facilities will be used to benchmark the adequacy of system codes, such as RELAP5 and TRAC, for predicting abnormal plant transients. The individual tests are described in detail in Volumes 2 through 8 and Volume 11, and are summarized in Volume 1. Inter-group comparisons are addressed in this document, Volume 9. These comparisons are grouped as follows: mapping versus SBLOCA transients, SBLOCA, pump effects, and the effects of noncondensible gases. Appendix A provides an index and description of the microfiched plots for each test, which are enclosed with the corresponding Volumes 2 through 8. 147 figs., 5 tabs

    The implementation of an integrated system health management (ISHM) capability is fundamentally linked to the management of data, information, and knowledge (DIaK) with the purposeful objective of determining the health of a system. It is akin to having a team of experts who are all individually and collectively observing and analyzing a complex system, and communicating effectively with each other in order to arrive at an accurate and reliable assessment of its health. In this paper, concepts, procedures, and approaches are presented as a foundation for implementing an intelligent systems ]relevant ISHM capability. The capability stresses integration of DIaK from all elements of a system. Both ground-based (remote) and on-board ISHM capabilities are compared and contrasted. The information presented is the result of many years of research, development, and maturation of technologies, and of prototype implementations in operational systems.

    The lower port systems are installed inside the vacuum vessel lower ports and in the adjacent port cells. The vacuum vessel ports and penetrations are allocated as follow: -4 ports dedicated to remote handling of the divertor cassettes, contain diagnostics racks and divertor cooling pipes. -5 ports connecting the main vessel to the torus cryopumps, contain divertor cooling pipes, pellet and gas injection pipes and vertical stabilization coil feeders. -3 penetrations connecting torus cryopumps are connected to the vacuum vessel by branch pipes. -Specific penetrations for divertor cooling lines, in-vessel viewing and glow discharge systems. The general layout of the port systems has been revised recently to improve the cryopump (8 t weight, 1.8 m diameter and 2.5 m long) maintenance scheme with remote handling tools and integrate the in-vessel vertical stabilization coil feeders. The port allocation, the pumping ports design, and interfaces in-between ports and cryostat and in-between cryopumps and cryostat have been up-dated. The integration inside the 18 port cells (11 m x 4 m each) has been reviewed to avoid clashes in between systems and to fix the openings in the port cell concrete walls. The new layout integrates safety and neutron-shielding requirements as well as remote handling and maintenance compatibility for the different systems. The paper presents the up-dated integration of the lower port systems inside the ports and the port cells. Interfaces of the port systems with the vacuum vessel, the cryostat and the port cells are described.

    World attention is now attracted to the concept of Novel Horizontally Integrated Energy System (NHIES). In NHIES, all fossil fuels are fist converted into CO and H 2 . Potential environmental contaminants such as sulfur are removed during this process. CO turbines are mainly used to generate electric power. Combustion is performed in pure oxygen produced through air separation, making it possible to completely prevent the formation of thermal NOx. Thus, NHIES would release very little amount of such substances that would contribute to acid rain. In this system, the intermediate energy sources of CO, H 2 and O 2 are integrated horizontally. They are combined appropriately to produce a specific form of final energy source. The integration of intermediate energy sources can provide a wide variety of final energy sources, allowing any type of fossil fuel to serve as an alternative to other types of fossil fuel. Another feature of NHIES is the positive use of nuclear fuel to reduce the formation of CO 2 . Studies are under way in Japan to develop a new concept of integrated energy system. These studies are especially aimed at decreased overall efficiency and introduction of new liquid fuels that are high in conversion efficiency. Considerations are made on the final form of energy source, robust control, acid fallout, and CO 2 reduction. (Nogami, K.)

    Full Text Available This paper presents an adaptation of the Integral Masonry System (IMS developed in Europe under the “AllWall System” trade name for concrete or clay, block or brick masonry walls using just mortar. In this case the system is modified for an adobe block infill to allow the construction of earthquake resistant housing in developing countries. When adobe block is employed as an infill it is impossible to transfer the bond stresses of the reinforcement bars as these structures are not bonded with mortar and the reinforcement then has to transfer the stresses purely within the reinforcement. The truss-shaped reinforcement may intersect in the three spatial directions and allow the construction of reinforced walls and slabs. It is then only necessary to infill with locally made adobe blocks or flooring in order to provide sufficient rigidity to the structure. A two-storey, 6x6x6 m, adobe building employing the IMS system has been tested for earthquake resistance at half scale at the PCUP (Pontificia Universidad Católica del Peru in Lima in collaboration with the UPM (Universidad Politécnica de Madrid to test the viability of this new type of building construction for seismic areas in the Third World.

We conclude that both recycle and structure influence in theperformance of the control system, and this influence can be foreseen by controllability and resiliency indicators.

    The articles in this volume are based on lectures from a program on integrable systems and differential geometry held at Taiwan's National Center for Theoretical Sciences. As is well-known, for many soliton equations, the solutions have interpretations as differential geometric objects, and thereby techniques of soliton equations have been successfully applied to the study of geometric problems. The article by Burstall gives a beautiful exposition on isothermic surfaces and their relations to integrable systems, and the two articles by Guest give an introduction to quantum cohomology, carry out explicit computations of the quantum cohomology of flag manifolds and Hirzebruch surfaces, and give a survey of Givental's quantum differential equations. The article by Heintze, Liu, and Olmos is on the theory of isoparametric submanifolds in an arbitrary Riemannian manifold, which is related to the n-wave equation when the ambient manifold is Euclidean. Mukai-Hidano and Ohnita present a survey on the moduli space of ...

    The main aim of this research work is to design an accurate and reliable monitoring system to be integrated with solar electricity generating system. The performance monitoring system is required to ensure that the PVEGS is operating at an optimum level. The PV monitoring system is able to measure all the important parameters that determine an optimum performance. The measured values are recorded continuously, as the data acquisition system is connected to a computer, and data is stored at fixed intervals. The data can be locally used and can also be transmitted via internet. The data that appears directly on the local monitoring system is displayed via graphical user interface that was created by using Visual basic and Apache software was used for data transmission The accuracy and reliability of the developed monitoring system was tested against the data that captured simultaneously by using a standard power quality analyzer device. The high correlation which is 97% values indicates the level of accuracy of the monitoring system. The aim of leveraging on a system for continuous monitoring system is achieved, both locally, and can be viewed simultaneously at a remote system.

    This paper describes the various features of the seismic module of the CARES system (computer analysis for rapid evaluation of structures). This system was developed to perform rapid evaluations of structural behavior and capability of nuclear power plant facilities. The CARES is structural in a modular format. Each module performs a specific type of analysis i.e., static or dynamic, linear or nonlinear, etc. This paper describes the features of the seismic module in particular. The development of the seismic modules of the CARES system is based on an approach which incorporates major aspects of seismic analysis currently employed by the industry into an integrated system that allows for carrying out interactively computations of structural response to seismic motions. The code operates on a PC computer system and has multi-graphics capabilities

    This report presents the results of a study of nonthermal treatment technologies. The study consisted of a systematic assessment of five nonthermal treatment alternatives. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The alternatives considered were innovative nonthermal treatments for organic liquids and sludges, process residue, soil and debris. Vacuum desorption or various washing approaches are considered for treatment of soil, residue and debris. Organic destruction methods include mediated electrochemical oxidation, catalytic wet oxidation, and acid digestion. Other methods studied included stabilization technologies and mercury separation of treatment residues. This study is a companion to the integrated thermal treatment study which examined 19 alternatives for thermal treatment of MLLW waste. The quantities and physical and chemical compositions of the input waste are based on the inventory database developed by the US Department of Energy. The Integrated Nonthermal Treatment Systems (INTS) systems were evaluated using the same waste input (2,927 pounds per hour) as the Integrated Thermal Treatment Systems (ITTS). 48 refs., 68 figs., 37 tabs.

    We present a generalization of a framework for the construction of classical integrable systems that we call loop coproduct formulation (Musso 2010 J. Phys. A: Math. Theor. 43 434026). In this paper, the loop coproduct formulation includes systems of Gelfand-Tsetlin type, the linear r-matrix formulation, the Sklyanin algebras, the reflection algebras, the coalgebra symmetry approach and some of its generalizations as particular cases, showing that all these apparently different approaches have a common algebraic origin. On the other hand, all these subcases do not exhaust the domain of applicability of this new technique, so that new possible directions of investigation do naturally emerge in this framework.

    The physical design of electric substations involves a variety of activities, such as developing, reviewing and performing modifications to different design proposals, estimating costs and producing documents to be integrated into an executive project. These activities are usually conducted at the Distribution Divisions of the Federal Electric Commission (CFE) through two separate processes: the development of engineering plans with computer-aided design software (CAD) and volumetric calculations for the initial budget using conventional spreadsheets. The documents are manually developed on an individual basis, without the existence of any functions to allow for automatically updating the design modifications of any of the plans. The corresponding initial budget becomes a lengthy and laborious process with the likelihood of inconsistencies among the documents. In order to optimize the design process for the public and electromechanical works of electric substations (ES) in a three-dimensional (3D) graphic environment, the IIE's Management of Process Supervision, in coordination with the CFE Distribution Subdivision, developed the System for the Design of Electric Substation Distribution (SDESD). This system makes use of the advantages of CAD3D technology to develop detail engineering, cost engineering to calculate initial budgets and virtual reality for three-dimensional interactive navigation. It is worth mentioning that this system is currently in the implementation phase at the CFE Distribution Subdivision. This article briefly describes the main stages in the development of the project, as well as the functioning and principal components of the system.

    The aim is to demonstrate the benefit of the medico-ergonomic approach for the redesign of clinical work systems. Based on the six layer model, a concept for an 'integrated therapy safety management' is drafted. This concept could serve as a basis to improve resilience. The concept is developed through a concept-based approach. The state of the art of safety and complexity research in human factors and ergonomics forms the basis. The findings are synthesized to a concept for 'integrated therapy safety management'. The concept is applied by way of example for the 'medication process' to demonstrate its practical implementation. The 'integrated therapy safety management' is drafted in accordance with the six layer model. This model supports a detailed description of specific work tasks, the corresponding responsibilities and related workflows at different layers by using the concept of 'bridge managers'. 'Bridge managers' anticipate potential errors and monitor the controlled system continuously. If disruptions or disturbances occur, they respond with corrective actions which ensure that no harm results and they initiate preventive measures for future procedures. The concept demonstrates that in a complex work system, the human factor is the key element and final authority to cope with the residual complexity. The expertise of the 'bridge managers' and the recursive hierarchical structure results in highly adaptive clinical work systems and increases their resilience. The medico-ergonomic approach is a highly promising way of coping with two complexities. It offers a systematic framework for comprehensive analyses of clinical work systems and promotes interdisciplinary collaboration. © 2013 The Authors.

    Full Text Available Objetivou-se com este trabalho avaliar o efeito do atrazine em mistura com nicosulfuron sobre a atividade microbiológica do solo em sistema de cultivo convencional ou semeadura direta. O estudo foi realizado em área de integração milho-braquiária, sendo feitas aplicações dos herbicidas atrazine + nicosulfuron em duas dosagens (1.500 + 10 e 1.500 + 30 g h-1 e mantidas duas áreas testemunhas: não capinada e capinada sem cultivo. Por ocasião do florescimento, foram retiradas amostras do solo em cada unidade experimental, para determinação da taxa de desprendimento de CO2, carbono da biomassa microbiana (CBM e quociente metabólico (qCO2. Entre os sistemas de cultivo, a taxa de desprendimento de CO2 foi menor nas parcelas não capinadas. O CBM foi maior no sistema de plantio direto, sendo afetado negativamente pela ausência de vegetação. Menores valores para CBM foram observados nas amostras de solo das parcelas capinadas. Os maiores valores de qCO2 foram observados no sistema convencional. No sistema de plantio direto não se verificou diferença entre os tratamentos cujo solo recebeu herbicida e o isento de capinas. Dessa forma, pode-se concluir que os indicadores microbiológicos avaliados foram sensíveis aos tratamentos propostos, indicando menor distúrbio ao solo quando em sistema de semeadura direta. Entretanto, na integração lavoura-pecuária em sistema convencional de cultivo, o efeito negativo dos herbicidas é aumentado com o incremento na dose do nicosulfuron.This study aimed to evaluate the effect of atrazine + nicosulfuron on soil microbial activity, under the conventional and no-tillage systems.

    The objective of this paper is to offer considerations about agroenergy production from biomass in integrated agroforestry systems. At present, worldwide, marked by a group of hazards that threaten human existence, there is a challenge mainly in the rural context: how can the coexistence of agroenergy, food security and environmental protection be achieved?, in the presence of climate changes, environmental degradation, food crises and the growing biofuels vs food contradiction, generated by a senseless policy for obtaining first-generation agrofuels from large extensions of food monocrops, which is morally rejectable. Biofuels are also considered an ecological alternative to fossil fuels, because of their reduction capacity in the emission of greenhouse gasses and because they promote the development of rural communities in southern countries; this is enhanced in integrated agroforestry systems, in which biofuels, of first as well as second generation, can be produced, especially with the application of the concept of biorefinery which allows converting biomass into many products, which total added value can be higher than the one generated by fossil fuels. International projects, which promote integrated and sustainable food and energy production in the context of agroforestry integrated systems, at local scale, contribute to this purpose. The authors consider that the execution of projects and experiences about agroenergy has the main objective of achieving energetic sustainability and food security at local scale, in rural areas, taking into account environmental protection.

The research was driven by end user requirements in protective security, particularly in threat detection and assessment, where effective capability was either not available or prohibitively expensive. Novel video analytics have been designed to provide robust detection of pedestrians in clutter while new radar detection and tracking algorithms provide wide area day/night surveillance. A modular integrated architecture based on commercially available components has been developed. A graphical user interface allows intuitive interaction and visualisation with the sensors. The fusion of video, radar and other sensor data provides the basis of a threat detection capability for real life conditions. The system was designed to be modular and extendable in order to accommodate future and legacy surveillance sensors. The current sensor mix includes stereoscopic video cameras, mmWave ground movement radar, CCTV and a commercially available perimeter detection cable. The paper outlines the development of the system and describes the lessons learnt after deployment in a pilot trial.

    Several integrable systems of nonlinear ordinary differential equations of the Lotka-Volterra type are identified by the Painleve property and completely integrated. One such integrable case of N first order ode's is found, with N - 2 free parameters and N arbitrary. The concept of integrability of a general dynamical system, not necessarily derived from a hamiltonian, is also discussed.

    This paper describes the strategy developed by M-I SWACO Brasil for identification of the need for implementation and management of a system that in an integrated way attended to the requirements of Quality, Health, Environment and Safety in the processes of drilling, completion and work over fluids and waste management in the E and P activities involving all steps, from planning to execution of the projects. The Integrated Management System was based on requirements of the international standards ISO 9001:2000, ISO 14001:1996 and OHSAS 18001:1999 and on internal corporate requirements as the HSE Management System. The conception of IMS is associated to a preventive posture, with the identification, evaluation and control of environmental and occupational risks, as well as the compliance to the products quality requirements and services related to the processes of fluids and waste management, with a systemic vision in that all those segments were managed in a integrated way. The system propitiated a better management of the processes and of the aspects of Quality, Health, Environment and Safety, increasing the awareness and the proactive attitude with the commitment of all levels of the company, adding value in the services and products, being a differentiation factor for customers, suppliers and community.

    This paper describes the various features of the Seismic Module of the CARES system (Computer Analysis for Rapid Evaluation of Structures). This system was developed by Brookhaven National Laboratory (BNL) for the US Nuclear Regulatory Commission to perform rapid evaluations of structural behavior and capability of nuclear power plant facilities. The CARES is structured in a modular format. Each module performs a specific type of analysis i.e., static or dynamic, linear or nonlinear, etc. This paper describes the features of the Seismic Module in particular. The development of the Seismic Module of the CARES system is based on an approach which incorporates all major aspects of seismic analysis currently employed by the industry into an integrated system that allows for carrying out interactively computations of structural response to seismic motions. The code operates on a PC computer system and has multi-graphics capabilities. It has been designed with user friendly features and it allows for interactive manipulation of various analysis phases during the seismic design process. The capabilities of the seismic module include (a) generation of artificial time histories compatible with given design ground response spectra, (b) development of Power Spectral Density (PSD) functions associated with the seismic input, (c) deconvolution analysis using vertically propagating shear waves through a given soil profile, and (d) development of in-structure response spectra or corresponding PSD's. It should be pointed out that these types of analyses can also be performed individually by using available computer codes such as FLUSH, SAP, etc. The uniqueness of the CARES, however, lies on its ability to perform all required phases of the seismic analysis in an integrated manner. 5 refs., 6 figs

    This work is devoted to the analysis of the Automatic Control of Electrical Systems Generation of power, as of the information that generates the loop with Load-Frequency Control and the Automatic Voltage Regulator loop. To accomplish the analysis, the control classical theory and feedback control systems concepts are applied. Thus also, the modern theory concepts are employed. The studies are accomplished in the digital computer through the MATLAB program and the available simulation technique in the SIMULINK tool. In this thesis the theoretical and physical concepts of the automatic control of generation are established; dividing it in load frequency control and automatic voltage regulator loops. The mathematical models of the two control loops are established. Later, the models of the elements are interconnected in order to integrate the loop with load frequency control and the digital simulation of the system is carried out. In first instance, the function of the primary control in are - machine, area - multi machine and multi area - multi machine power systems, is analyzed. Then, the automatic control of generation of the area and multi area power systems is studied. The economic dispatch concept is established and with this plan the power system multi area is simulated, there in after the energy exchange among areas in stationary stage is studied. The mathematical models of the component elements of the control loop of the automatic voltage regulator are interconnected. Data according to the nature of each component are generated and their behavior is simulated to analyze the system response. The two control loops are interconnected and a simulation is carry out with data generated previously, examining the performance of the automatic control of generation and the interaction between the two control loops. Finally, the Poles Positioning and the Optimum Control techniques of the modern control theory are applied to the automatic control of an area generation

    We consider B-model large N duality for a new class of noncompact Calabi-Yau spaces modeled on the neighborhood of a ruled surface in a Calabi-Yau threefold. The closed string side of the transition is governed at genus zero by an A 1 Hitchin integrable system on a genus g Riemann surface Σ. The open string side is described by a holomorphic Chern-Simons theory which reduces to a generalized matrix model in which the eigenvalues lie on the compact Riemann surface Σ. We show that the large N planar limit of the generalized matrix model is governed by the same A 1 Hitchin system therefore proving genus zero large N duality for this class of transitions

    Full Text Available Wind is an attractive renewable source of energy. Recent innovations in research and design have reduced to a few alternatives with limited impact on residential construction. Cost effective solutions have been found at larger scale, but storage and delivery of energy to the actual location it is used, remain a critical issue. The Integrated Roof Wind Energy System is designed to overcome the current issues of urban and larger scale renewable energy system. The system is built up by an axial array of skewed shaped funnels that make use of the Venturi Effect to accelerate the wind flow. This inventive use of shape and geometry leads to a converging air capturing inlet to create high wind mass flow and velocity toward a vertical-axis wind turbine in the top of the roof for generation of a relatively high amount of energy. The methods used in this overview of studies include an array of tools from analytical modelling, PIV wind tunnel testing, and CFD simulation studies. The results define the main design parameters for an efficient system, and show the potential for the generation of high amounts of renewable energy with a novel and effective system suited for the built environment.

    Structural analysis of the piping system for nuclear power plants has become larger in scale and in quantity. In addition, higher quality analysis is regarded as of major importance nowadays from the point of view of nuclear plant safety. In order to fulfill to the above requirements, an integrated piping structural analysis system (ISAP-II) has been developed. Basic philosophy of this system is as follows: 1. To apply the date base system. All information is concentrated. 2. To minimize the manual process in analysis, evaluation and documentation. Especially to apply the graphic system as much as possible. On the basis of the above philosophy four subsystems were made. 1. Data control subsystem. 2. Analysis subsystem. 3. Plotting subsystem. 4. Report subsystem. Function of the data control subsystem is to control all information of the data base. Piping structural analysis can be performed by using the analysis subsystem. Isometric piping drawing and mode shape, etc. can be plotted by using the plotting subsystem. Total analysis report can be made without the manual process through the reporting subsystem. (author)

Without any doubts one of the most serious problems facing the complex management and optimization of these systems is related to the variability of the thermal load and the regulation possibilities of the thermal machines, so as to attain, along the day an appropriate use and optimization of the total installed load, with the best possible economic benefits. Among the strategies that allow the optimization of the installed capacity and the variability of the thermal load is the low temperature thermal storage, for instance, the storage of ice, which is produced and stored to be used when the cooling machines are in standby in order to use this stored energy during the peak hours and during the normal operation of the equipment, but diminishing in a significant amount the electrical demand of the system to satisfy the thermal load with a combination thermal storage-cooling machine.

    Electrical distribution systems ought to deliver electric power as economical as possible with an acceptable degree of service quality and continuity. Nevertheless, their faults represent one of the main causes of customer's unavailability. At the moment, a wide range of determinist criteria in the improvement of systems reliability based on past behavior are used, but they do not respond to the stochastic nature of system behavior, and are applied without an adequate balance between reliability and economy. In order to obtain this balance a minimum cost planning methodology that considers the predictive analysis of different investment alternatives in addition to the past behavior of the system is required, which guarantees that the economic resource available and limited will be used to gather the greater possible reliability degree. In this work this problem is approached with the fundamentals and methodologies needed to assess the design effects and operative criteria over the main reliability indexes used by the main utilities around the world, with emphasis on the need to optimize economical resources. The use of the system SynerGEETM, is investigated, probing it as a useful tool for the predictive reliability analysis. Due to the lack of experience that exists in Mexico with this type of analysis, distribution engineers has to become familiar with the concepts of the reliability engineering, their application to establish distribution systems models, and acquiring the ability to use the modern simulation tools, allowing them to evaluate the behavior of these systems with enough analytical rigor. In this sense a serial of well known study cases are presented to help them in this labor.

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

    Approximately 1,000 stack and occupation air samples from plutonium and uranium facilities at LASL are analyzed daily. The concentrations of radio-nuclides in air are determined by measuring absolute alpha activities of particulates collected on air sample filter media. The Integrated Minicomputer Pulse system (IMPULSE) is an interface between many detectors of extremely simple design and a Digital Equipment Corporation (DEC) PDP-11/04 minicomputer. The detectors are photomultiplier tubes faced with zinc sulfide (ZnS). The average detector background is approximately 0.07 cpm. The IMPULSE system includes two mainframes, each of which can hold up to 64 detectors. The current hardware configuration includes 64 detectors in one mainframe and 40 detectors in the other. Each mainframe contains a minicomputer with 28K words of Random Access Memory. One minicomputer controls the detectors in both mainframes. A second computer was added for fail-safe redundancy and to support other laboratory computer requirements. The main minicomputer includes a dual floppy disk system and a dual DEC 'RK05' disk system for mass storage. The RK05 facilitates report generation and trend analysis. The IMPULSE hardware provides for passage of data from the detectors to the computer, and for passage of status and control information from the computer to the detector stations

    The monitoring of industrial plants by virtual instrumentation represents the most modern trend in the domain of electronic equipment. The integrated vacuum system presented here has several facilities, including the automated data storing of measurement results on hard disk and providing warning messages for operators when the measured parameters are lower or higher upper than the fixed values. The system can also work stand-alone, receiving the commands from the keyboards placed on his front panel but, when it is included in a automation complex system, a remote control from PC is necessary . Both parts of the system, power supply unit for turbo-molecular pump and the vacuum gage, are controlled by an 80C31 microcontroller. Because this microcontroller has a built-in circuitry for a serial communication, we established a serial communication between the PC and the power supply unit for turbo-molecular pump and the vacuum gage, according to the RS-232 hardware standard. As software, after careful evaluation of several options, we chose to develop a hybrid software packing using two different software development tools: LabVIEW, and assembly language. We chose LabVIEW because it is dedicated to data acquisition and communications, containing libraries for data collection, analysis, display and storage. (authors)

    Aiming to ensure continuity in the electrical supply to critical processes, the electrical systems of large industrial plants, i.e. gas, and petrochemical industries usually posses local generation. Should the local generation be enough to satisfy the demand of the plant, then the interconnection with the public grid is commonly used as an important support for emergency conditions. This paper is concerned with the dynamical performance of two interconnected industrial power systems tied to the transmission system. Simulation results indicate that the frequency performance of one of the industrial plants, after the transients caused by the loss of the tie with the transmission system have died out, is greatly improved if both industrial plants remain connected after the disturbance. [Spanish] La continuidad en el suministro de energia electrica a procesos criticos de grandes complejos industriales, tales como plantas petroquimicas, procesadoras de gas, etc., es un aspecto de fundamental importancia para garantizar una operacion adecuada de este tipo de complejos. Con el proposito de mejorar la confiabilidad en el suministro de energia a los procesos criticos, los sistemas electricos de estos complejos industriales, generalmente cuentan con generacion propia. Si la capacidad de generacion instalada en los sistemas industriales es suficiente para satisfacer el total de la carga del complejo, la interconexion con el sistema de transmision es utilizada principalmente como respaldo durante condiciones de emergencia. En este articulo se analiza el comportamiento dinamico de dos sistemas industriales con generacion propia, disenados para operar en forma aislada, interconectados entre si, a traves de un enlace de 115 kV y con el sistema de transmision. Los resultados obtenidos indican que el comportamiento de la frecuencia en estado estable en uno de los complejos, posterior a la perdida del enlace con el sistema de transmision, mejora de manera considerable cuando estos

These will help to obtain, organise, administrate, evaluate and control particulars: information, quality, environmental protection, health and safety, various resources (time, human, finance, inventory etc. The complexity of nowadays days development, forced us to think ‘integrated’. Sustainable development principles require that environment management policies and practices are not good in themselves but also integrate with all other environmental objectives, and with social and economic development objectives. The principles of sustainable development involve that environment management policies and practices. These are not sound in them-self but also integrate with all other environmental objectives, and with social and economic development objectives. Those objectives were realized, and followed by development of strategies to effects the objective of sustainable development. Environmental management should embrace recent change in the area of environmental protection, and suit the recently regulations of the field -entire legal and economic, as well as perform management systems to meet the requirements of the contemporary model for economic development. These changes are trailed by abandon the conventional approach of environmental protection and it is replaced by sustainable development (SD.

    Full Text Available In the book "Eat Right For Your Type" the author Peter J. D'Adamo writes that the O blood type was the first blood type to appear in humans and affirms that the blood groups are the key to the immune system. Some recent phylogenetic network studies in humans and non-human primates implies that the A gene represents an ancient form of the ABO genes. Relationships between blood groups and infectious and noninfectious diseases and immunodeficiency abnormalities have also been reported in the literature. As D'Adamo's propositions seem to be in opposition with the current knowledge, we present in this paper some comments about the genetics and the evolution of the ABO blood group genes and some links between this blood system and the functioning of the immune system.Peter J.

    Hybrid power systems for an autonomous power supply are based on different renewable and fossil energy sources. They are considered as a good option for the power supply of remote areas. In these systems an energy storage is a vital necessity and very often this storage will consist of batteries which are generally connected in series and parallel arrays, or both. In Mexico as in other countries, the most extensively use batteries used for this application are the stationary and electric car type deep cycle batteries. However the experience with them in these systems is generally not very good. One way to overcome this problem is to maintain a regular monitoring of installing monitoring equipment, in order to make preventive actions before a developing fault can have serious consequences and in this manner increase the practical lifetime of the batteries. Unfortunately, battery monitoring is not easy task because most of the hybrid power systems are installed in remote areas which makes it difficult and expensive. In Mexico it has been not possible to maintain a regular monitoring of all hybrid power systems installed, due to the high cost of this work and the lack of founds. The hybrid power systems installed in the state of Quintana Roo are the only systems that have been continuously monitored since their installation. This paper gives an overview of the hybrid power systems installed in Mexico, focusing in the battery banks, the way they are being monitored, the main parameters used to detect possible premature problems and the method used to evaluate the battery bank conditions.

    The proliferation of Integrated Delivery Systems (IDSs) in regional health care markets has resulted in the movement of these markets from a monopolistic competitive model of behavior to an oligopoly. An oligopoly is synonymous with competition among the few, as a small number of firms supply a dominant share of an industry's total output. The basic characteristics of a market with competition among the few are: (1) A mutual interdependence among the actions and behaviors of competing firms; (2) competition tends to rely on the differentiation of products; (3) significant barriers to entering the market exist; (4) the demand curve for services may be kinked; and (5) firms can benefit from economies of scale. An understanding of these characteristics is essential to the survival of IDSs as regional managed care markets mature.

    The computer program SYSOPT, intended as a tool for optimizing the subsystem sizing, performance, and economics of integrated wind and solar energy systems, is presented. The modular structure of the methodology additionally allows simulations when the solar subsystems are combined with conventional technologies, e.g., a utility grid. Hourly energy/mass flow balances are computed for interconnection points, yielding optimized sizing and time-dependent operation of various subsystems. The program requires meteorological data, such as insolation, diurnal and seasonal variations, and wind speed at the hub height of a wind turbine, all of which can be taken from simulations like the TRNSYS program. Examples are provided for optimization of a solar-powered (wind turbine and parabolic trough-Rankine generator) desalinization plant, and a design analysis for a solar powered greenhouse.

    Six sites are now disposing of most of DOE's currently generated waste. These are: Hanford, Idaho National Engineering Laboratory, Los Alamos National Laboratory, the Nevada Test Site, Oak Ridge, and Savannah River. Within DOE, experience with disposal of solid LLW has been that arid site disposal facilities (first four) appear to have performed well, while humid site disposal facilities (last two) have experienced some waste migration. DOE's intent, of course, is to operate all its waste disposal facilities so that public health and safety are not adversely affected. To ensure that this continues to be the case, activities are underway to increase use of waste form stabilization and engineered barriers where appropriate. For the sake of overall economy, these measures are to be applied as and where needed, through use of the systems approach. In this paper the author discusses two topics: the system approach, which DOE has decided to use for resolving waste disposal problems in the management of DOE's low-level wastes; and DOE's intended integration of activities underway at the waste management systems throughout DOE facilities. 2 figures

    Advanced integrated solvent extraction systems are a series of novel solvent extraction (SX) processes that will remove and recover all of the major radioisotopes from acidic-dissolved sludge or other acidic high-level wastes. The major focus of this effort during the last 2 years has been the development of a combined cesium-strontium extraction/recovery process, the Combined CSEX-SREX Process. The Combined CSEX-SREX Process relies on a mixture of a strontium-selective macrocyclic polyether and a novel cesium-selective extractant based on dibenzo 18-crown-6. The process offers several potential advantages over possible alternatives in a chemical processing scheme for high-level waste treatment. First, if the process is applied as the first step in chemical pretreatment, the radiation level for all subsequent processing steps (e.g., transuranic extraction/recovery, or TRUEX) will be significantly reduced. Thus, less costly shielding would be required. The second advantage of the Combined CSEX-SREX Process is that the recovered Cs-Sr fraction is non-transuranic, and therefore will decay to low-level waste after only a few hundred years. Finally, combining individual processes into a single process will reduce the amount of equipment required to pretreat the waste and therefore reduce the size and cost of the waste processing facility. In an ongoing collaboration with Lockheed Martin Idaho Technology Company (LMITCO), the authors have successfully tested various segments of the Advanced Integrated Solvent Extraction Systems. Eichrom Industries, Inc. (Darien, IL) synthesizes and markets the Sr extractant and can supply the Cs extractant on a limited basis. Plans are under way to perform a test of the Combined CSEX-SREX Process with real waste at LMITCO in the near future.

    Based on lectures given at an advanced course on integrable systems at the Centre de Recerca Matemàtica in Barcelona, these lecture notes address three major aspects of integrable systems: obstructions to integrability from differential Galois theory; the description of singularities of integrable systems on the basis of their relation to bi-Hamiltonian systems; and the generalization of integrable systems to the non-Hamiltonian settings. All three sections were written by top experts in their respective fields. Native to actual problem-solving challenges in mechanics, the topic of integrable systems is currently at the crossroads of several disciplines in pure and applied mathematics, and also has important interactions with physics. The study of integrable systems also actively employs methods from differential geometry. Moreover, it is extremely important in symplectic geometry and Hamiltonian dynamics, and has strong correlations with mathematical physics, Lie theory and algebraic geometry (including mir...

    The central systems of air conditioning are widely used in air conditioning production for several reasons among which excel: 1) Better aesthetic of the building, 2) Less noise in the air conditioning premises and 3) Greater yield of the consumed energy. This is indeed the third reason in which this paper will try to contribute with elements that will allow reveal the problem and to identify some possible causes that originate it. The centralized systems of air conditioning must produce conditioned air with lesser power cost than the individual systems, it is that saving which allows to recover an investment that normally surpasses them in 3 to 5 times. Nevertheless, the real numbers do not demonstrate that. [Spanish] Los sistemas centrales de climatizacion son ampliamente usados en la produccion de aire acondicionado por varias razones entre las que sobresalen: 1) Mejor estetica del edificio, 2) Menor ruido en los locales climatizados y 3) Mayor rendimiento de la energia consumida. Es precisamente la tercera razon en la cual este trabajo intentara aportar elementos que permitan develar el problema e identificar algunas posibles causas que lo originan. Los sistemas centralizados de climatizacion deben producir aire acondicionado con un menor gasto energetico que los sistemas individuales, es precisamente ese ahorro lo que permite recuperar una inversion que normalmente los supera en 3 a 5 veces. Sin embargo, los numeros reales no demuestran eso.

    The objective of this paper is to explain the programs that are contained in a Thermodynamic Computer System. Students can use this Computer System to make complicated calculations that are required in Thermodynamic Analysis. One of this programs is used to obtain the expression of heat capacity of pure substances in terms of temperature, at constant pressure. A database of pure substances has been created which retrieves the thermodynamic properties (enthalpy, entropy and Gibbs free energy) in such a format that it is very easy to understand. The changes of state functions for chemical reactions can also be calculated. Another program is used to estimate the equilibrium conditions in multicomponent and multiphase systems. [Spanish] En el presente trabajo se muestran los programas de computo que conforman un Sistema de Analisis Termodinamico desarrollado con el fin de facilitar los calculos y la comprension de algunos principios de la Termodinamica. Este sistema permite obtener la funcionalidad de la capacidad calorifica con la temperatura de sustancias puras, a presion constante; obtener de manera rapida y concisa las propiedades termodinamicas (entalpia, entropia y energia libre de Gibbs) de elementos y compuestos puros almacenados en una base de datos; determinar los cambios en las funciones de estado de reacciones quimicas entre sustancias puras; determinar el equilibrio en sistemas multicomponentes y multifasicos. Se indican los alcances de este grupo de programas de computo asi como su aplicacion a procesos practicos.

    2014-07-01

    Full Text Available Phosphorylation of serine, threonine and tyrosine plays significant roles in cellular signal transduction and in modifying multiple protein functions. Phosphoproteins are coordinated and regulated by a network of kinases, phosphatases and phospho-binding proteins, which modify the phosphorylation states, recognize unique phosphopeptides, or target proteins for degradation. Detailed and complete information on the structure and dynamics of these networks is required to better understand fundamental mechanisms of cellular processes and diseases. High-throughput technologies have been developed to investigate phosphoproteomes in model organisms and human diseases. Among them, mass spectrometry (MS-based technologies are the major platforms and have been widely applied, which has led to explosive growth of phosphoproteomic data in recent years. New bioinformatics tools are needed to analyze and make sense of these data. Moreover, most research has focused on individual phosphoproteins and kinases. To gain a more complete knowledge of cellular processes, systems biology approaches, including pathways and networks modeling, have to be applied to integrate all components of the phosphorylation machinery, including kinases, phosphatases, their substrates, and phospho-binding proteins. This review presents the latest developments of bioinformatics methods and attempts to apply systems biology to analyze phosphoproteomics data generated by MS-based technologies. Challenges and future directions in this field will be also discussed.

    Control systems constitute the brain and the nervous system of modern machines, such as wind turbine generators (TGE by its acronym in Spanish). TGEs can work efficiently, safely and almost autonomously, thanks to the control systems with which they are equipped. Conversely, any malfunctioning of the control system may cause failure or damage of a component, a subsystem or even destruction of the TGE itself. This paper introduces some basic facts about generation of electric power from wind energy in the world and Mexico, wind turbogenerators and their most relevant technologies, TGE control systems, and R and TD+I about TGE control systems performed at the Instituto de Investigaciones Electricas.

    Full Text Available O desenvolvimento de sistemas robóticos para cirurgia teve início na década de 80, por solicitação do exército norte-americano, que antevia a possibilidade de realizar operações em teatros de guerra, distantes do local onde estava o cirurgião. Entretanto, o primeiro uso em humanos só ocorreu anos mais tarde, numa ressecção transuretral de hiperplasia benigna de próstata. Cirurgiões cardíacos foram logo atraídos pela técnica robótica devido a possível aplicação com reduzido caráter invasivo; esperava-se menor trauma cirúrgico e redução da dor, morbidade, tempo de internação e custo do procedimento. Atualmente, de forma restrita e em casos selecionados, robôs são usados para revascularização do miocárdio e implante de marcapasso em cirurgias cardíacas totalmente endoscópicas; podendo também constituir apoio visual na retirada de artéria torácica interna, reconstrução valvar mitral e correção de defeitos congênitos. Utilizando o robô auxiliar AESOP® para controle do videotoracoscópio, com controle vocal por meio do sistema HERMES®, temos realizado dissecção da artéria torácica interna, implante de eletrodo ventricular esquerdo e abordagem de defeitos congênitos na cirurgia de correção. Apesar do entusiasmo científico inicial com a cirurgia robótica, ainda não existe evidência clara de superioridade desta técnica em relação à operação convencional, em termos de resultado. Isto se aplica também ao custo, pois o investimento inicial na aquisição de sistema cirúrgico completo (console, controle de vídeo, instrumental provavelmente é compensado após muitos procedimentos e longo intervalo. Mas é certo que a cirurgia robótica terá um lugar no futuro, possibilitando aprendizagem, telepresença e realização de procedimentos pouco invasivos, embora complexos.The development of robotic systems for surgery started in the 80's, motivated by the US army's need for surgical procedure in

    The paper discusses a system of measuring and recording units intended for use in a wide range of physical experiments. The basis of the system is a 256-channel register unit with a channel capacity of 2{sup 16} and a control unit. The system is executed on ferrite cores and transistors. The arithmetic element of the register unit makes it possible to perform adding and subtracting operations. The time of a complete cycle up t o the memory is 20 {mu}s. In the control unit, the basic controls, such as the settings for registering, counting and recording, can be combined in any order, which gives a much wider range of application as compared with normal equipment. The frequency of the control unit is taken from a 4-Mc/s quartz generator. As measuring units the system employs a pulse-amplitude-to-cipher code converter with a conversion time of 0.25 {mu}s per channel, integral non-linearity better than 0.1%, differential non-linearity less than 4%, zero drift less than 0.2 V and channel-width instability less than 0,4%, for lengthy periods. The converter system employs tubes. The time selector, which employs transistors, has a channel width from 1 to 64 {mu}s; the channel-width instability is less than 10{sup -4}. The logic of the circuit is such as to permit registration of incomplete pulses into the channel for channel widths of more than 8 {mu}s. The unit used to convert small time-intervals (10{sup -9} - 10{sup -7} s.) into a unitary cipher code has a time resolution of about 2 x 10{sup -5} s and a channel width stability better than 10{sup -2}. From the memory unit the information can be passed either in an analogue form to an oscillograph tube or in the form of cipher code to a printer and indicator lamps.

The work process flow style has been revised to better describe Project work and the relationships of participants. For each work process, more background and guidance on ''why'' and ''what is expected'' is given. For example, a description of activity data sheets has been added in the work organization and the Project performance and reporting processes, as well as additional detail about the federal budget process and funding management and improved flow charts and explanations of cost and schedule management. A chapter has been added describing the Cost Reduction/Productivity Improvement Program. The Change Control Board (CCB) procedures (Appendix A) have been updated. Project critical issues meeting (PCIM) procedures have been added as Appendix B. Budget risk assessment meeting procedures have been added as Appendix C. These appendices are written to act as stand-alone documentation for each process. As the procedures are improved and updated, the documentation can be updated separately

  9. Cotangent Models for Integrable Systems

    Science.gov (United States)

    Kiesenhofer, Anna; Miranda, Eva

    2017-03-01

    We associate cotangent models to a neighbourhood of a Liouville torus in symplectic and Poisson manifolds focusing on b-Poisson/ b-symplectic manifolds. The semilocal equivalence with such models uses the corresponding action-angle theorems in these settings: the theorem of Liouville-Mineur-Arnold for symplectic manifolds and an action-angle theorem for regular Liouville tori in Poisson manifolds (Laurent- Gengoux et al., IntMath Res Notices IMRN 8: 1839-1869, 2011). Our models comprise regular Liouville tori of Poisson manifolds but also consider the Liouville tori on the singular locus of a b-Poisson manifold. For this latter class of Poisson structures we define a twisted cotangent model. The equivalence with this twisted cotangent model is given by an action-angle theorem recently proved by the authors and Scott (Math. Pures Appl. (9) 105(1):66-85, 2016). This viewpoint of cotangent models provides a new machinery to construct examples of integrable systems, which are especially valuable in the b-symplectic case where not many sources of examples are known. At the end of the paper we introduce non-degenerate singularities as lifted cotangent models on b-symplectic manifolds and discuss some generalizations of these models to general Poisson manifolds.

    A 3 × 3 matrix Lie algebra is first introduced, its subalgebras and the generated Lie algebras are obtained, respectively. Applications of a few Lie subalgebras give rise to two integrable nonlinear hierarchies of evolution equations from their reductions we obtain the nonlinear Schrödinger equations, the mKdV equations, the Broer-Kaup (BK) equation and its generalized equation, etc. The linear and nonlinear integrable couplings of one integrable hierarchy presented in the paper are worked out by casting a 3 × 3 Lie subalgebra into a 2 × 2 matrix Lie algebra. Finally, we discuss the elliptic variable solutions of a generalized BK equation. (general)

    We give the basic definitions and some theoretical results about hyperdeterminants, introduced by A Cayley in 1845. We prove integrability (understood as 4D consistency) of a nonlinear difference equation defined by the 2 x 2 x 2-hyperdeterminant. This result gives rise to the following hypothesis: the difference equations defined by hyperdeterminants of any size are integrable. We show that this hypothesis already fails in the case of the 2 x 2 x 2 x 2-hyperdeterminant.

    Full Text Available OBJECTIVE: to investigate the socially-relevant communication of the nursing system from the Luhmannian perspective. METHOD: the investigation process was based in grounded theory. The data was collected between February and September 2011, through interviews carried out with nurses and student nurses at a university in the South of Brazil. RESULTS: The central phenomenon - recognizing nursing care as an all-embracing interactive and associative phenomenon - resulted from the inter-weaving of three categories: learning the context of care as a whole, organizing the environment for the other professionals, and visibilizing interactive and associative care. CONCLUSION: investing in a socially relevant communication for nursing entails developing a code for functional differentiation, which may strengthen health promotion and healthy living for individuals, families and communities.OBJETIVO: conocer la comunicación socialmente relevante del sistema de enfermería en la perspectiva luhmanniana.

    We describe an application of the Temez model to calculate total water influx in a natural regime and its division into its surface and groundwater components. We also suggest a suitable way of integrating the data series obtained into the SIMGES conjunctive use code. The literature offers a considerable number of precipitation-runoff models for calculating the total influx into a basin. Within this context the Temez model is a relatively simple code which in certain cases has decided advantages over more complex ones, as we point out in this paper. For a better understanding of this model, we include an annex showing its mathematical basis. We used the Temez model to calculate the surface and groundwater influx into the Cornisa-Vega de Granada water system, which comprises 25 river sub-basins, 5 reservoirs and 23 aquifers, meaning that the interrelation between surface water and groundwater is quite complex and difficult to assess. In addition to this, some points of the series are quite difficult to calibrate because the natural regime of the water system is being considerably altered by human activity. We analyse the four parameters used in the Temez model together with the factors affecting both its calibration and the reliability and uncertainties of the results deriving from its application.

    In the last years there has been an increasing interest on IORT (Intraoperative Radiation Therapy), also because of the development of dedicated accelerators. This technique represents a very effective oncological treatment consisting in delivering a single high dose on a tumour bed soon after surgery resection. In the following we present the proposal of development of a last generation IORT system based on the use of a linear accelerator with variable energy in the range 3-15 MeV, operating in C band (5712 MHz). Respect to the accelerator used in the commercial IORT systems operating at a typical frequency of 2998 MHz (S band) limited to a maximum energy of 12 MeV, the use of a higher RF frequency allows an increase of the maximum energy. This extends the use of the IORT technique to a wider field of tumors and an improvement of the system in terms of compactness and weight reduction. In addition the machine will be provided with a devoted absolute dosimetry system that will strongly simplify the procedures of dosimetric characterization. We intend to develop the system by a collaboration between ENEA, some Universities (Bologna, Catanzaro and Cosenza) and the national industry.

    In the last years there has been an increasing interest on IORT (Intraoperative Radiation Therapy), also because of the development of dedicated accelerators. This technique represents a very effective oncological treatment consisting in delivering a single high dose on a tumour bed soon after surgery resection. In the following we present the proposal of development of a last generation IORT system based on the use of a linear accelerator with variable energy in the range 3-15 MeV, operating in C band (5712 MHz). Respect to the accelerator used in the commercial IORT systems operating at a typical frequency of 2998 MHz (S band) limited to a maximum energy of 12 MeV, the use of a higher RF frequency allows an increase of the maximum energy. This extends the use of the IORT technique to a wider field of tumors and an improvement of the system in terms of compactness and weight reduction. In addition the machine will be provided with a devoted absolute dosimetry system that will strongly simplify the procedures of dosimetric characterization. We intend to develop the system by a collaboration between ENEA, some Universities (Bologna, Catanzaro and Cosenza) and the national industry. [Italian] Negli ultimi anni si e sviluppato un sempre maggior interesse intorno alla Radioterapia IntraOperatoria (IORT), una particolare tecnica radioterapica che permette di irradiare la zona interessata da un tumore durante un intervento chirurgico utilizzando un fascio di elettroni prodotto da un acceleratore. La diffusione di questa metodica e stata favorita dalla presenza sul mercato di acceleratori installabili direttamente in sala operatoria. Come conseguenza di questa disponibilita sono emerse sia nuove esigenze legate alle particolari applicazioni cliniche, sia richieste di facilita di utilizzo e perfomances sempre piu sofisticate. Viene qui presentata una proposta di sviluppo di un sistema IORT di ultima generazione basato sull'utilizzo di un acceleratore lineare con energia

  20. Observadores Distribuidos Garantistas para Sistemas en Red

    Full Text Available Resumen: En este artículo se propone un observador distribuido garantista para sistemas en red, considerando de forma explícita el problema de los retardos variables en las comunicaciones. Se asume que la información intercambiada entre agentes llega siempre a su destino, si bien las comunicaciones están sujetas a retardos variables, cuyo valor máximo se supone conocido. Cada observador trabaja con información parcial, y necesita comunicarse con observadores vecinos para llevar a cabo una estimación del estado completo del sistema. Para representar a los conjuntos garantistas, cuya función es acotar en tiempo real la región en la que se encuentra el estado del sistema, se ha optado por la utilización de zonotopos. Esto permite integrar de forma sencilla la información recibida por cada agente. Finalmente se presentan resultados de simulación para validar el algoritmo propuesto. Abstract: This paper proposes a guaranteed distributed observer for networked systems, taking into account the problem of the variable delays in communications. We assume that the information exchanged among the agents always arrives to its destination, although the communication are subject to variable delays, whose maximum value is known. Each observer works with partial information, and needs to communicate with neighbouring observers to carry out an estimation of the complete state of the system. The guaranteed sets, whose function is to delimit in real time the region in which the state of the system belong to, are represented by zonotopes. This kind of sets allows a simple integration of the information received by each agent. Finally some results obtained with the proposed algorithm are shown in simulations.

    Full Text Available Com base no modelo da análise quantitativa das representações sociais, o estudo (N = 300 tratou do posicionamento de estudantes universitários em relação aos Direitos Humanos (DHs e à ancoragem social desse posicionamento nos sistemas de valores dos estudantes. Os resultados mostram que as representações dos estudantes sobre o envolvimento nos DHs envolvem quatro princípios organizadores: pessoal-abstrato; pessoal-concreto; governamental-abstrato; governamental-concreto. Em relação à ancoragem social dos princípios organizadores do envolvimento nos DHs, observou-se que os valores pós-materialistas se relacionaram positivamente com o envolvimento pessoal-abstrato, enquanto a adesão aos valores religiosos implicou maior envolvimento no princípio pessoal-concreto. Além disso, a adesão aos valores materialistas levou a uma avaliação mais positiva do envolvimento do Governo Brasileiro nos DHs, ao passo que os valores pós-materialistas contribuíram com uma avaliação mais crítica desse governo. As discussões abordam a centralidade dos valores na formação das representações sociais dos DHs.Based on the quantitative analysis model of social representations, a study (N=300 was carried out concerning the opinion of university students on Human Rights (HR, and the social link of this positioning in the students system of values. The results show that the students representations of the involvement in HR comprise four organizing principles: personal-abstract; personal-concrete; governmental-abstract; governmental-concrete. With regard to the social anchorage of the organizing principles of involvement in HR, it has been observed that post-materialist values were positively related to the involvement personal-abstract, whereas adherence to religious values implied a greater involvement in the personal-concrete principle. In addition, adherence to materialist values led to a more positive appraisal of the Brazilian Government

The study took place at the restaurant (R.U. of the State University of Londrina (UEL. After gathering information and relevant data and analyzing the results obtained, it was possible to verify that the follow-up system in the purchase procedure is informally used in that location, despite its importance. It could also be noticed that the university does not use the same system with the other units that integrate it. When comparing a public and a private company it is possible to conclude that the system used in a private company is more complete, as it is considered a routine procedure of the purchase department. As for the logistics system which integrates the purchase system, it was possible to verify that there are flaws in its conception and use, generating deviation and loss of resources used in the public sector. Some possible ways to solve the raised problems were pointed out, such as: the possibility of adopting the system of public concession in the same way that it is adopted in other public services in the city of LondrinaO artigo analisa a aplicabilidade do sistema de acompanhamento em compras e da logística numa organização pública. O local estudado foi o restaurante universitário (R.U. na Universidade Estadual de Londrina.

    Full Text Available O linfoma primário do sistema nervoso central (LPSNC é um linfoma extralinfonodal que, ao diagnóstico, encontra-se restrito ao parênquima cerebral, às meninges e/ou cordão espinhal e/ou olhos. Sua incidência triplicou nas últimas três décadas para 0,4 casos por 100.000 habitantes, representando 4% dos tumores do sistema nervoso central (SNC. Embora pacientes infectados pelo HIV tenham 3.600 vezes maior risco para o desenvolvimento do LPSNC, a incidência não aumentou apenas neste grupo de pessoas. Dados sugerem reduções da incidência de LPSNC em pacientes infectados após a introdução de drogas anti-retrovirais. Cerca de 90% dos casos de LPSNC são classificados como linfoma difuso de grandes células B, 10% têm envolvimento ocular e 10% são HIV positivos. A apresentação clínica depende da localização tumoral, prevalecendo os sintomas neurológicos em detrimento aos sistêmicos. Os exames de tomografia computadorizada (TC e ressonância nuclear magnética (RNM são essenciais para o diagnóstico, porém o exame confirmatório deve ser o anatomopatológico. O estadiamento deve ser feito com exames de imagem e biópsia de medula óssea (BMO bilateral. Os principais fatores de mau prognóstico são: performance status do paciente acima de 1, idade superior a 60 anos, DHL elevada, hiperproteinorraquia e acometimento de área cerebral não hemisférica. Alguns fatores de prognóstico biológicos também podem influenciar na sobrevida, a exemplo da expressão de Bcl-6, que confere melhor prognóstico. O tratamento de escolha é a combinação de quimioterapia contendo altas doses de metotrexate e radioterapia (RDT. Devido às altas taxas de neurotoxicidade associada à RDT, seu uso tem ficado mais restrito aos pacientes idosos, e os recidivados ou refratários.Primary Central Nervous System lymphoma (PCNSL is an extranodal non-Hodgkin lymphoma in the brain, leptomeninges, spinal cord or eyes.
