    1994-12-31

    The validity of the premise that proposes the privatization of the electric sector as a solution to the problem of obtaining enough investment capital for the continuous expansion of the electric sector is examined. It is shown that the growth of the demand foreseen for the residential sector for year 2000, can be totally reduced by introducing technologies economically feasible to increase the efficiency and end uses of the residential electricity. With the efficient use of the electricity, the economical development is allowed for the residential sector, without large increments of the residential electricity demand. [Espanol] Se examina la validez de la premisa que propone la privatizacion del sector electrico como una solucion al problema de conseguir suficientes capitales de inversion para la continua expansion del sector. Se muestra que se puede reducir casi totalmente el crecimiento en la demanda prevista del sector residencial al ano 2000, introduciendo tecnologias economicamente factibles para aumentar la eficiencia en los usos finales de electricidad residencial. Con el uso eficiente de la electricidad, se permite el desarrollo economico del sector residencial sin grandes incrementos en la demanda residencial de electricidad.

    The evolution of the activities related to the electric efficiency before and after the reforms of the electrical sector in Peru derived from the liberation of the economy is explained. In the first part it is explained as an antecedent the development of one of the most successful campaigns regarding demand management, considering it as a variable and not as a datum of the problem for statistic effects. The results of such campaign demonstrated that a proper management of the variable electricity demand, capital investments can be deferred in the electric infrastructure within the frame of sustainable social development. Afterwards it is explained the new regulatory frame and the principles that prevail for the fixation of the tariffs when the electrical sector evolves from a vertical structure to a horizontal structure. Finally it is mentioned the activities that have been carried out in a latter period to the implantation of the reforms in the sector and some important examples such as the obligation for the electric utilities to reduce their technical and commercial losses.

    Historically, the electrical systems were constituted from local networks of small scale that were added together progressively to benefit from the effects of a more abundant demand and of the economies of scale in generation, that authorize the large interconnected systems. This logic at the moment seems to show certain limits, the factors that influence these technologies can vary greatly from one country to another, but nevertheless it is found in different degrees certain constants such as the search for a greater reliability in the electrical supply, the putting into work prevention policies of climatic change or the reforms of the electrical sector. In this work the influence of these factors was examined insisting particularly on the consequences of the opening of the electrical sector, departing from an analysis of the international experience in a first time and later examining the case of Mexico in the context of the present energy situation and the debate of the energy reform. The distributed generation: a new vector of technological opportunities in the electrical sector, the barriers for the diffusion of the distributed generation: the lessons of the international experience, the institutional problematic of the distributed generation within the effective legal framework of Mexico. [Spanish] Historicamente, los sistemas electricos se constituyeron a partir de redes locales de pequena escala que se fueron agregando progresivamente para beneficiarse de los efectos de una demanda mas abundante y de las economias de escala en generacion que autorizan los grandes sistemas interconectados. Esta logica parece actualmente mostrar ciertos limites, los factores que influyen sobre estas tecnologias pueden variar grandemente de un pais al otro, pero se encuentra, sin embargo, a grados diferentes ciertas constantes tales como la busqueda de una confiabilidad mas grande en el aprovisionamiento electrico, la puesta en obra de politicas de prevencion de cambio

    The beginning of electricity in Mexico was through the use and exploitation of natural resources; as the demand grew, more generation power plants were required with great capacity and at the same time the fuels used varied, although, oil continued to be the main fuel. At present, due to the effects of climate change, the Conference of the Parties has proposed to reduce the consumption of fossil fuels to give way to clean energy (wind, solar, geothermal, nuclear, etc.), which entails gradually modifying the energy matrix of the electricity sector. The National Development Plan and the National Electricity Sector Development Program, this coordinated by the Energy Secretariat in Mexico, establish policies to promote sustainable development, increasing electricity generation through clean energy sources, including nuclear energy. However, such plans are not accurate in the strategy to be followed to ensure compliance with the increased participation of nuclear energy. This article proposes a nuclear program for the Mexican electricity sector, under the terms of a State policy, aimed at crystallizing a sustainable electricity development 2015-2036; considering that the application to the electricity sector constitutes a representative and justified example of the incorporation of environmental aspects in decision processes for the preservation of the environment. In order to determine the quantity and type of reactors, as well as the number of nuclear power plants and increase of the installed capacity, the general planning scheme of the electric sector was used, taking as reference the modeling criteria of the WASP planning system. Finally, is concluded that the electricity generated by fission of radioactive elements is an opportunity to fulfill the commitments made by Mexico at COP 21 and to meet in an environmentally friendly way the energy requirement that our country needs.

    Full Text Available En América Latina, el paso de una ciudad compacta a una ciudad dispersa no solo ha implicado transformaciones territoriales y funcionales de las grandes urbes; también ha contribuido a modificar la escala de la segregación social que en ellas existe, proceso en el que han desempeñado un papel central los cambios de residencia de la población urbana. En Chile, la capital nacional no ha sido una excepción a esta dinámica, en la medida en que los cambios residenciales en curso han alterado la segregación residencial, tanto en su escala espacial como en las formas que adopta. Los resultados alcanzados en este estudio muestran una marcada concentración de grupos socioeconómicos de mayor estatus en entidades administrativas de la ciudad que, hasta hace poco tiempo, no eran valoradas como lugares de residencia permanente por estas categorías de población. Esto ha incrementado a otras escalas la segregación, y ha contribuido a aumentar la complejidad del modelo general de segregación residencial de la ciudad.

    Among the actions taken after the crisis of electricity supply at the beginning of this decade, the replacement of incandescent lamps for compact fluorescent lamps (CFL's, about four times more efficient than the incandescent) is one of most important. This paper develops an assessment of the impact of this measure in terms of energy saved and demand reduction, especially associated with the use of CFL's lamps in the residential sector. According to this study, which took into account the park of lamps installed in Brazilian households (38% efficient) and an average time of use of 1,000 hours per year, nowadays lightning in the residential sector corresponds to a peak demand reduction for 4,800 MW and a consumption of about 16,000 GWh, approximately 20% of whole residential sector consumption in 2005. The introduction of more efficient lamps has induced an economy of 6,858 GWh, approximately 8% of consumption observed in 2005. (author)

  6. El control de las concentraciones empresariales en el sector electrico

    Montoya Pardo, Milton Fernando

    The rampant success of quantum theory is the result of applications of the 'new' quantum mechanics of Schrodinger and Heisenberg (1926-7), the Feynman-Schwinger-Tomonaga Quantum Electro-dynamics (1946-51), the electro-weak theory of Salaam, Weinberg, and Glashow (1967-9), and Quantum Chromodynamics (1973-); in fact, this success of 'the' quantum theory has depended on a continuous stream of brilliant and quite disparate mathematical formulations. In this carefully concealed ferment there lie plenty of unresolved difficulties, simply because in churning out fabulously accurate calculational tools there has been no sensible explanation of all that is going on. It is even argued that such an understanding is nothing to do with physics. A long-standing and famous illustration of this is the paradoxical thought-experiment of Einstein, Podolsky and Rosen (1935). Fundamental to all quantum theories, and also their paradoxes, is the location of sub-microscopic objects; or, rather, that the specification of such a location is fraught with mathematical inconsistency. This project encompasses a detailed, critical survey of the tangled history of Position within quantum theories. The first step is to show that, contrary to appearances, canonical quantum mechanics has only a vague notion of locality. After analysing a number of previous attempts at a 'relativistic quantum mechanics', two lines of thought are considered in detail. The first is the work of Wan and students, which is shown to be no real improvement on the iisu.al 'nonrelativistic' theory. The second is based on an idea of Dirac's - using backwards-in-time light-cones as the hypersurface in space-time. There remain considerable difficulties in the way of producing a consistent scheme here. To keep things nicely stirred up, the author then proposes his own approach - an adaptation of Feynman's QED propagators. This new approach is distinguished from Feynman's since the propagator or Green's function is not obtained by Feynman's rule. The type of equation solved is also different: instead of an initial-value problem, a solution that obeys a time-symmetric causality criterion is found for an inhomogeneous partial differential equation with homogeneous boundary conditions. To make the consideration of locality more precise, some results of Fourier transform theory are presented in a form that is directly applicable. Somewhat away from the main thrust of the thesis, there is also an attempt to explain, the manner in which quantum effects disappear as the number of particles increases in such things as experimental realisations of the EPR and de Broglie thought experiments.

    Porcelain is the insulating material more extensively used for electric insulators manufacturing, due to its dielectric properties; nevertheless, it presents fragility problems of manufacture and of resistance to the thermal shock, among others. For this reason studies are being conducted for the substitution of porcelain in the electric insulators manufacturing. In this area, the Instituto de Investigaciones Electricas developed an improved insulating formulation - the polymeric concrete- and an industrial prototype machine for the manufacture of high voltage electric insulators for outdoors use. [Espanol] La porcelana es el material aislante electrico mas utilizado en la elaboracion de aisladores electricos, debido a sus propiedades dielectricas; sin embargo, presenta problemas de fragilidad, de fabricacion y de baja resistencia al choque termico, entre otros. Es por ello que se realizan estudios para sustituir la porcelana en la fabricacion de aisladores electricos. En este campo, el Instituto de Investigaciones Electricas desarrollo una formulacion aislante mejorada -el concreto polimerico- y una maquina prototipo industrial para fabricar aisladores electricos de alto voltaje para uso en exteriores.

    This paper analyses the changes in equipment in dwellings and the residential energy consumption for end uses in Mexico in the 1984-1994 decade. The study is based in data of the Instituto Nacional de Estadistica, Geografia e Informatica (INEGI)`s Income-Expense in Homes National Survey and in estimates of the unit consumption of the household appurtenances. The most important results show that food cooking represents 64% of the residential energy consumption, 22% water heating, 4% lightning and 10% electric appurtenances and other uses of LP gas and natural gas. The devices of greater saturation in 1994 were the gas stove (87%), the iron (85%), the TV (85%) and the refrigerator (64%). In analysis of the equipment there is a serious inequity in the country. The number of dwellings that have electric household devices or appurtenances requiring the supply of energy services greatly depend on the income level of the same.

    The normalization in Mexico, in what it refers to this century that is about to end, it could be said that it goes back and is having important changes in different stages, starting in 1928 with the appearance of the Law of Weights and Measures, in 1945 with the issue of the Law of Industrial Standards, in 1961 with the appearance of the General Law of Standards, Weights and Measures, in 1988 with the emission of the Federal Law on Metrology and Standardization in which still the standards were considered Official Mexican Standards, until July 1, 1992 in which appears a new Federal Law On Metrology and Standardization in which the standards could be classified in Mexican Official Standards and Mexican Standards, the first ones of forced fulfillment and second ones of voluntary character. Also, in this Law appear new terms and actors in the scope of the standardization and certification, so to speak, these actors are the Laboratories of Calibration and Tests, the Organisms of Standardization, the Organisms of Certification and the Units of Verification. In 1998 appear the Reforms to the Law and where a new figure appears that is the identity of accreditation and whose object and main activity is to recognize the technical competition and trustworthiness of the Organisms of Certification, of the Testing Laboratories, the Laboratories of Calibration and the Units of Verification for the evaluation of the conformity, and on March 15, 2001 appears in the Diario Oficial de la Federacion (Official Newspaper of the Federation) the Regulation of the Federal Law on Metrology and Standardization in order to have a document of support for its correct interpretation. [Spanish] La normalizacion en Mexico, en lo que data de este siglo que esta por terminar, podria decirse que se remonta y va tendiendo cambios importantes en diferentes etapas, iniciando en 1928 con la aparicion de la Ley de Pesas y de Medidas, en 1945 con la expedicion de la Ley de Normas Industriales, en 1961 con la aparicion de la Ley General de Normas, Pesas y Medidas, en 1988 con la emision de la Ley Federal sobre Metrologia y Normalizacion, en la cual todavia las normas eran consideradas Normas Oficiales Mexicanas, SINDO hasta el 1 de julio de 1992 en que aparece una nueva Ley Federal Sobre Metrologia y Normalizacion en la que las normas se podrian clasificar en Normas Oficiales Mexicanas y Normas Mexicanas, las primeras de obligado cumplimiento y las segundas de caracter voluntario. Asimismo, en esta Ley aparecen nuevos terminos y actores en el ambito de la normalizacion y certificacion, por asi decirlo, dichos actores son los Laboratorios de Calibracion y de Pruebas, los Organismos de Normalizacion, los Organismos de Certificacion y las Unidades de Verificacion. En 1998 aparecen las Reformas a la Ley y donde aparece una nueva figura que es la de la entidad de acreditacion y cuyo objeto y principal trabajo es el de reconocer la competencia tecnica y confiabilidad de los Organismos de Certificacion, de los Laboratorios de Prueba, de los Laboratorios de Calibracion y de las Unidades de Verificacion para la evaluacion de la conformidad, y el 2001 el 15 de marzo aparece en el diario Oficial de la Federacion el eglamento a la Ley Federal sobre Metrologia y Normalizacion a efecto de tener un documento de apoyo para su correcta interpretacion.

Por otra parte, a los usuarios del servicio publico de energia, el instituir dentro de sus politicas operativas programas de ahorro y conservacion de la energia, indudablemente les redundara en beneficios economicos y se mejorara el indice de kWh/Unidad de producto terminado. Finalmente, en un pais como el nuestro en donde el 66% de la energia generada por el sector electrico nacional proviene de centrales termoelectricas que usan para su operacion combustibles fosiles, la implementacion generalizada de programas de ahorro de energia disminuira la necesidad de generar kWh, y en consecuencia, la emision de contaminantes agresivos al medio ambiente tales como oxidos de nitrogeno y de azufre, bioxido de carbono y particulas suspendidas.

    Full Text Available Los análisis sobre segregación residencial en Chile, están adquiriendo una importancia creciente, dado que sus efectos sociales son cada vez más evidentes. A objeto de identificar las tendencias que sigue este proceso, se hace una revisión de la investigación a nivel nacional y que permita ser un aporte para el avance en este tema. Los resultados indican que la segregación residencial está disminuyendo, los principales mecanismo que operan en este proceso son: el funcionamiento del mercado del suelo, políticas públicas y los movimientos migratorios al interior de la ciudad.Comoefecto, la segregación ha generado un aumento de los problemas sociales como el alcoholismo, delincuencia, jóvenes solteras embarazadas y deserción escolar. También se observa una predominancia de estudios cuantitativos y una significativa heterogeneidad en el uso de indicadores, como un escaso análisis sobre la percepción y autopercepción de los habitantes de barrios segregados.

    This article synthesizes the main projection results for final use of energy consumed by residential sector on the next 20 years in Brazil, and evaluates their implications for a strategy of energetic sustainable development in Brazil. Arising out of previous studies performed for the Petroleum Brazilian Institute, for the Brazilian Ministry of Mines and Energy and for the IAEA, this article considers two sceneries: reference (REF) which considers significant changes, beyond those already consolidated; alternative (ALT), which considers progressive changes in the structure of residential sector (proportion of residences by income by revenue level and consumption), the energetic efficiency and a augmented participation of 'clean' energy sources. Both sceneries estimates potential growing of residences, gain of energetic efficiency, participation of commercial sources and use of natural gas in Brazil, and the rhythm of the implementation. The results show that the difference between the final use of energy by residential sector in REF (33.7 MtEP) in 2023 and in ALT (30.5 MtEP in 2023) can reach almost 10% during the next 20 years.

    Full Text Available Las actuales mayores necesidades residenciales metropolitanas se han suscitado principalmente por la modificación de las relaciones de parentesco, que han dado lugar a un aumento en las jefaturas de hogar y la consecuente contracción del tamaño promedio de los hogares. Junto con el avance de las políticas de desalarización de la economía metropolitana, el mercado inmobiliario de la residencia nueva en Bogotá produce un incremento en el stock que no atiende satisfactoriamente los dos grandes desafíos que representan la densificación urbana y la producción de un orden residencial metropolitano menos segregado. El ajuste espacial del mercado formal se apoya tanto en la reducción de las áreas residenciales para hogares de bajos ingresos como en su localización periférica, lo que implica mayor hacinamiento y más altos costos de transporte para sus miembros.The increase in metropolitan residential needs has arisen mainly from changing family relationships resulting in an increase in household headships and the ensuing contraction of their average size. Amid the advancement of "desalarization" labor policies in the metropolitan economy, the housing market of new residences in Bogotá has produced an increase in the residential stock that does not cover sufficiently the major challenges presented by urban densification, and by the production of a less segregated metropolitan residential order. Theformal market's spatial adjustment is based both on the reduction of residential areas for low-income households, and their peripheral location, which implies an increase in overcrowding and transportation costs for their members.

    Full Text Available The aim of this paper is to study the residential environment and its perception by the elderly people ageing in place in Madrid, to obtain a better knowledge of the elements to modify in order to increase their satisfaction. The Censo de Población y Vivienda (1991 and the Survey Ageing in Place (1998 are used. In general terms, old people live in old houses, as owners, not crowded but with lack of facilities. These people have been living for a long time in the same neighbourhood, an environment affected by the problems characteristic of big cities, and are integrated in the neighbour by means of activities requiring not to much physical or financial effort. Residential lacks affect mainly to that groups with social and economic vulnerability: female, lower income and educational level, worse health status,... So, two out ten aged people would move mainly due to the negative conditions of habitability, adaptation and facilities. Moreover, reasons for not moving are related to the force of habit, the memories, or consequence of age, bad health or less resources.

    [es] El entorno residencial de los mayores en Madrid. El objetivo de este artículo es estudiar el ámbito residencial de los mayores que envejecen en su casa y la percepción que tienen sobre este medio, para obtener un mejor conocimiento de los aspectos que deberían modificarse a fin de incrementar su satisfacción. Las fuentes utilizadas son el Censo de Población y Vivienda de 1991 y la Encuesta Envejecer en Casa de 1998. A grandes rasgos, los viejos madrileños viven en casas viejas, de las que son propietarios, sin problemas de hacinamiento pero con carencias dotacionales. Durante la mayor parte de su vida adulta han residido en el mismo barrio, un entorno que actualmente está afectado por los problemas propios de las grandes ciudades, y en el que se integran socialmente mediante actividades que no requieren demasiado esfuerzo físico o monetario.

    2004-01-01

    Full Text Available El objetivo de este trabajo es analizar cuatro componentes de la movilidad residencial intraurbana de los residentes de la ciudad de Bogotá (Colombia: la elección de la vivienda, de su localización, del tipo de tenencia, y la decisión de lograr una autonomía residencial. Cada una de ellas tiene su propia lógica, y ésta se analiza para cada individuo por medio de las trayectorias biográficas recabadas en 1993. Las diferenciaciones sociales cambian de un componente a otro, se agregan o se combinan, provocando variaciones en la movilidad residencial. En una ciudad en rápida expansión, con una notable segregación residencial, el interés por la localización es fundamental, a pesar de que poco se le ha considerado en la literatura que trata sobre el tema. El significado que confieren los individuos a la ubicación de su vivienda dentro de la ciudad rebasa la simple consideración de los recursos con que cuenta el barrio; atañe también a las historias familiares y a la historia de la ciudad.

    Full Text Available Pese a la emergente presencia de la segregación residencial socioeconómica (SRS en los debates académicos y en las agendas públicas, la evidencia en América Latina y el Caribe sobre su magnitud e intensidad, sus tendencias, sus mecanismos de reproducción y sus consecuencias es escasa, fragmentaria y poco comparable entre países (e incluso en términos diacrónicos para cada país. Al respecto, este trabajo procura ofrecer alguna evidencia empírica sobre la SRS con especial referencia a la situación de América Latina y el Caribe, buscando aportar en cuatro sentidos: (a avanzar en la medición de la SRS en los países de la región; (b profundizar en el examen de sus determinantes directos, en particular en los patrones de migración intrametropolitana; (c reflexionar sobre las disparidades de comportamiento y condiciones de vida entre zonas ricas y pobres, como primer antecedente para el examen de las consecuencias de la SRS; (d revisar opciones de política relativas a la SRS a nivel internacionalIn spite of the growing relevance of the socioeconomic residential segregation (SRS in academic debates and public agendas in Latin American and the Caribbean, the evidence regarding its intensity and magnitude, its tendencies, its reproductive mechanisms and consequences, is fragmentary and weak. Moreover there is little work on comparative indicators of socioeconomic residential segregation between countries (or even in a diachronic way for each country. In this regard, this document offers some pieces of empiric evidence about this social phenomenon, focused in Latin America cities. It aims to contribute in four directions: (a to advance in the measurement of the SRS in the countries of the region; (b to study its determinants, especially the intra-metropolitan migration patterns; (c to explore disparities in behavior and life conditions between rich and poor areas, as first step for the study of the consequences of the SRS; (d to revise

    Directory of Open Access Journals (Sweden)

    Francisco Sabatini

    2000-05-01

    Full Text Available La temprana y radical liberalización de los mercados urbanos chilenos tuvo consecuencias inesperadas en los precios del suelo y en la segregación residencial en Santiago: los precios del suelo ha crecido persistentemente desde la eliminación en 1979 de la norma sobre "límites urbanos" y otras reformas; y la segregación ha reducido su escala geográfica en importantes áreas, debido a la acción del robusto sector inmobiliario privado surgido en los años ochenta. Se trata de dos fenómenos de relevancia para el desarrollo urbano, en general, y que tienen un impacto directo en el grave problema de la pobreza urbana, en particular: los precios del suelo condicionan el acceso de los pobres al suelo; y el patrón de segregación residencial, sus perspectivas de integración social. Estos hechos, lo mismo que sus implicaciones para la política urbana, han sido, en lo principal, descuidados tanto por el gobierno como por los investigadoresThe early and radical liberalization of Chilean urban land markets has had unexpected consequences on land prices and on residential segregation in Santiago: prices have grown persistently after the elimination in 1979 of the law on "urban limits" and other market-oriented reforms; and segregation has reduced its geographical scale in important parts of the city due to the action of the strong private real estate sector that emerged in the 1980s. These two are relevant facts for urban development, in general, and have a direct impact on the compelling problem of urban poverty, in particular: land prices condition access to land on the part of the poor; and patterns of segregation, their prospects for social integration. These two facts, as well as their implications for urban policy, have been, for the most part, neglected both by the government and by researchers

    Full Text Available Se presenta un estudio ex post-facto de tipo descriptivo de medición única en un solo grupo que tiene como objetivo analizar la relación entre las conductas agresivas y de bullying de adolescentes en régimen de acogimiento residencial con su género y la práctica de actividad física. La participación de un total de 203 adolescentes en acogimiento residencial de la provincia de Granada (España permitió el registro y la evaluación de las siguientes variables: conducta violenta, bullying, nivel de práctica de actividad física y modalidad y parámetros sociodemográficos. Los resultados mostraron que los adolescentes varones en acogimiento residencial presentan medias más elevadas en agresividad manifiesta o directa, mientras que el género femenino presenta índices de agresividad relacional más elevados. Predomina la realización de actividad física mediante deportes colectivos de contacto, cuya práctica es más frecuente en varones. Asimismo, se aprecian valores similares por modalidad deportiva en comportamientos agresivos y de bullying en jóvenes en régimen de acogimiento residencial. Como principal conclusión se muestra que los comportamientos agresivos de tipo manifiesto y reactivo son los más comunes en los adolescentes en acogimiento residencial, lo que revela baja capacidad de autocontrol.

    A review is made of the energy resources in use existing at the moment for the electricity production (hydraulic, coal, oil, gas and uranium). The asymptotic energies (solar, geothermal and nuclear fission and fusion) are described and the state of development in which they are up to the moment. One concludes that in the case of Mexico it would be convenient to make flexible and to reinforce the electrical systems in forecast of a greater participation of the distributed generation and to orient the extensions of the electrical generation to make a greater use of the three asymptotic energies already used: the solar (in its forms hydraulic and wind power), geothermal and the nuclear fission. [Spanish] Se pasa revista a los recursos existentes en las energias actualmente en uso para la produccion de electricidad (hidraulica, carbon, petroleo, gas y uranio). Se describen las energias asintoticas (solar, geotermia y fision y fusion nucleares) y el estado de desarrollo en que se encuentran hasta el momento. Se concluye que en el caso de Mexico convendria flexibilizar y reforzar el sistema electrico en prevision de una mayor participacion de la generacion distribuida y orientar las ampliaciones de la generacion electrica para hacer un mayor uso de tres de las energias asintoticas ya utilizadas: la solar (en sus formas hidraulica y eolica), la geotermia y la fision nuclear.

    Given the dependence of our transport system in combustible hydrocarbons that, besides generating serious pollution levels, eventually will become scarce, severely affecting the world economy- it is compulsory to develop non polluting transportation, capable of operating with alternative energies. In the avant-guard of this technological achievement are the competition solar automobiles, that have made great contributions (particularly for the rigorous application of the design for efficiency principles) in the development of the applicable technology to the electric vehicles. Tonatiuh is the first competition solar car built in Mexico. In 1993 Tonatiuh will compete in the Rally Formula Sol in Mexico and in the World Solar of Australia. A superficial comparison of electric vehicles with vehicles equipped with internal combustion motors, demonstrates the great advantages of the first ones, most of all at the light of the current technological advances propitiated by laws that demand them for the sale of electric vehicles. This incipient industry presents a great opportunity for Mexico, since the markets are not saturated and exist large areas of research and development. For improvement of the air quality in Mexico city, the electric vehicle would have a very positive impact, mostly applied to public transportation.

    un sistema para la cuantificacion y estudio del contenido de armonicas en sistemas electricos. El estudio esta enfocado a senales de corriente de alimentacion de un horno de Arco Largo. El sistema desarrollado para la cuantificacion del contenido de armonicas esta formado por las siguientes partes: (a) Sistemas de adquisicion de datos: La aplicacion de un sistema de adquisicion de datos nos posibilita tomar muestras de una senal analoga de voltaje. Las muestras adquiridas que representan una senal analoga, pueden ser procesadas posteriormente en una computadora digital. El sistema de adquisicion de datos esta constituido por: Una microcomputadora IBM-PC, una tarjeta de digitalizacion de senales analogas y programacion para realizar el muestreo de las senales. (b) Procesamiento digital de senales adquiridas: Con el proposito de determinar el contenido armonico, se utilizo el metodo de la Transformada Rapida de fourier. El analisis mediante la Transformada Rapida de Fourier nos permite obtener el espectro de las senales en el dominio de la frecuencia. Mediante el analisis por medio de la transformada rapida de Fourier se tiene una disminucion sustancial en el tiempo de computo de los coeficientes correspondientes a las armonicas, esto comparado con el metodo de series discretas de Fourier. (c) Analisis de resultados obtenidos: Se realizaron varias mediciones de senales de corriente de linea y banco de capacitores del sistema de alimentacion de un horno de arco. Para cada medicion realizada se obtuvo la magnitud y la fase para cara armonica. Del conjunto de magnitudes y fases de los coeficientes, se calculo el valor promedio y su desviacion estandar. Se muestran graficas de la variacion de la magnitud y la fase de cada armonica con el tiempo. Asimismo, se tienen graficas de las formas de onda de la senal en analisis, diagramas de barras del contenido espectral promedio y un reporte de la desviacion estandar de la magnitud y la fase para cada armonica.

    In the nineties, the Instituto de Investigaciones Electricas (IIE) Electrical Equipment Management (GEE) was restricted to make the diagnosis of generators, transformers, switch boards and cables, without considering the global operating conditions. With the experience acquired in different services it was verified that, inclusively when this equipment is correctly designed, it can be subjected to unfavorable operative conditions, which causes an accelerated deterioration to the degree of producing a fault. In agreement with this, the GEE settled down new line of development named Analysis of the network effect on the electrical equipment, that analyzes the behavior of the equipment originated by work abnormal causes, including the network configuration effect. [Spanish] En la decada de los noventa, la Gerencia de Equipos Electricos (GEE) del IIE se limitaba a realizar el diagnostico de generadores, transformadores, tableros de distribucion y cables, sin considerar las condiciones globales de operacion.

    Since the early nineties Brazil has initiated a program of reforms in its electric sector which includes utility privatization, de-verticalization. The main objectives were to promote a market-oriented energy industry attractive to private investments. This has led to the loss of sponsorship for the public-interest programs formerly undertaken by the state utilities. In particular, of significant concern are the programs for promotion of energy efficiency, renewable energy technologies, rural electrification and environmental protection. In the midst of the privatization effort, the National Agency for Electrical Energy ANEEL was created (end of 1997). One of the tasks of the regulatory agency is to provide funds and incentives to energy conservation. In this paper we review the role of ANEEL in promoting energy efficiency investments in the context of a market-oriented sector, its limitations and prospects. [Spanish] Desde principios de los anos noventa Brasil ha iniciado un programa de reformas en su sector electrico que incluye la privatizacion del servicio electrico y la desverticalizacion. Los objetivos principales eran promover una industria de la energia orientada comercialmente de la energia electrica, atractiva a las inversiones privadas. Esto ha conducido a la perdida de patrocinio de los programas de interes publico emprendidos antes por las empresas electricas del estado. En particular, de preocupacion significativa estan los programas para la promocion del rendimiento energetico, de las tecnologias de la energia renovable, de la Electrificacion rural y de la proteccion del medio ambiente. En medio del esfuerzo de la privatizacion, la agencia nacional para la energia electrica ANEEL fue creada (finales de 1997). Una de las tareas de la agencia reguladora es proporcionar fondos e incentivos a la conservacion de energia. En este trabajo repasamos el papel de ANEEL en promover inversiones del rendimiento energetico en el contexto de un sector orientado

    Full Text Available El objetivo de este trabajo es presentar una propuesta teórica-conceptual para el abordaje de la movilidad residencial, en general, y de las trayectorias residenciales, en particular. Se busca comprender cómo a partir de la distribución y apropiación desigual de recursos sociales -materiales y simbólicos- se desarrollan trayectorias diferentes y cómo las estructuras socio-territoriales constriñen, modelan y habilitan interacciones entre las familias, entre sus miembros, y los diversos contextos de acción en pos de satisfacer sus necesidades de vivienda. A partir de aportes de distintas tradiciones sociológicas se presenta un esquema articulador que pone atención en las relaciones entre factores estructurales, posición en la estructura social y decisiones vinculadas a los cambios de residencia. Se concluye que las pautas de movilidad son pautas relacionales definidas en diálogo con las "oportunidades" y las "limitaciones" que se configuran en torno a la existencia de vivienda y tierra nueva o vacante, a la dinámica del mercado de suelo y vivienda, a la del mercado de trabajo, a la disposición de servicios de infraestructura y de equipamiento social, etc.

    Of the 30 countries that use nuclear energy, Japan was the third country with greater number of nuclear reactors and installed capacity; there were 54 nuclear reactors with an installed capacity of 46,343 MW, and the participation of the nuclear energy in the electricity generation of the country was of 33% in 2010. The Fukushima accident of March 11, 2011 due to natural forces not foreseen and with a very low occurrence probability with characteristics outside the design base, provoked questioning of the safety measures of the others 51 nuclear reactors that operated in Japan. This situation causes that the mentioned 51 nuclear reactors remain without generating electric power until to ensure its safety operation before the new risk conditions. Particularly, the Japanese electric system had combined cycle plants based on gas which were used of way load pick and backup that before this new situation, they must operate as base load sources. For Japan, the nuclear energy was a base load source reliable and economic since Japan does not possess enough own resources for its electricity generation. The market of the natural gas in Japan is at present one of the most expensive worldwide so that impacts negatively in the electricity generation cost. This work analyzes the measures taken to cover the loss of nuclear electricity generation, basically by means of the use of the combined cycle plants based on natural gas, and the impact that these measures had in the costs of electricity generation of the Japanese electric system. The obtained results in this analysis show that the national electricity generation cost was increased and collaterally the quantity of greenhouse gases emissions of the country also increased.

    Full Text Available Con base en la matriz de actitudes y comportamiento, esta investigación tuvo como objetivo analizar las actitudes de la población de un destino con respecto al turismo residencial en un destino mexicano. A partir de entrevistas en profundidad con residentes locales, el estudio corrobora las postulaciones de la matriz confirmando que las poblaciones en los destinos poseen actitudes y comportamientos heterogéneos, y que ambos pueden manifestarse de distintas maneras e intensidades. Sin embargo, revela que en el caso del turismo residencial, las actitudes favorables no están únicamente determinadas por los beneficios económicos sino por el tipo de relación social empática establecida entre locales y turistas, y las actitudes desfavorables están determinadas por la sensación de afectación colectiva como consecuencia de la implantación de proyectos de desarrollo turístico decididos externamente.

    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.

    This paper describes the organizational changes of the electric industry, accomplished or in the process of being implemented in various countries encompassing from the modality of the independent power producers with which the competitiveness at production level is pretended to be introduced, until the total disintegration of the electric systems by means of the separation of the generation, transmission and distribution functions and the intent of implementing the access of third parties to the transmission network. Finally, the risks that these reforms imply from the stand point of service quality and the environmental protection are pointed out [Espanol] En esta ponencia se describen los cambios de organizacion de la industria electrica, realizados o en vias de implantarse en varios paises, abarcando desde la modalidad de las empresas generadoras independientes con la que se pretende introducir la competencia al nivel de la produccion, hasta la desintegracion total de los sistemas electricos mediante la separacion de las funciones de generacion, transmision y distribucion, y la pretension de implantar el acceso de terceros a la red de transmision. Finalmente se senalan los riesgos que implican estas reformas desde el punto de vista de la calidad del servicio y de la preservacion del medio ambiente

    Full Text Available Within a context defined by globalized and flexible markets, by the increasing access to diverse forms of transport and communication, and by policies and fashions making mobility a value, people's reluctancy to move seems paradoxical. But, as various researches revised in this paper suggest, inmobility remains atractive in most European countries (specially in the South. Our research offers data confirming this hypothesis for the case of young people. Therefore, visions of globalization which project objective speed potentials to people's behaviour seem to be too deterministic and irreflective. Although transportation and telecommunication are generating many new and faster forms of mobility, a distinction is to be made between this speed potentials and their use. As far as use is preceded by motivation, a deeper exploration of subjective factors underlying this motivation is the aim of a sociology of mobility from the point of view of the actor.

    En una sociedad caracterizada por la globalización y flexibilización de los mercados, por la expansión y creciente accesibilidad de las formas de transporte y comunicación, y por las políticas y modas que hacen de la movilidad un valor, la renuencia de los individuos a la movilidad residencial puede parecer un fenómeno paradójico. Pero, tal y como se refleja en diversos informes y estudios revisados en este trabajo, el atractivo de la inmovilidad parece un hecho persistente en la mayoría de los países europeos (y especialmente en los del sur. Nuestra investigación aporta datos que confirman esta apreciación para el caso de los jóvenes, cuya supuesta asociación con la movilidad es resultado de una proyección precipitada y determinista sobre los comportamientos esperados del innegable incremento de las posibilidades objetivas de movilidad propiciadas por la extensión de la red de trasportes e información. Junto a este entorno objetivo de la movilidad, sin embargo, parecen existir

    Full Text Available In recent years, a variety of observers have denounced the housing conditions of Andalusia's growing immigrant population as largely miserable. In addition to the overcrowding in and the poor quality of housing available to immigrants, special emphasis has been placed on the confinement to extra-urban spaces in Andalusia's thriving areas of intensive agriculture, specifically in Almería province. Based on survey data, this article provides a far more reliable measurement of these three phenomena (overcrowding, poor quality housing and spacial exclusion than previously available, including social profiles of the people affected by these deficiencies. Our results point to the existence of sizable and serious problems with housing conditions specifically in this population. However, differently from previous studies, our data show that these particular problems affect a minority only of Andalusia's immigrants.

    En este artículo se describe la situación residencial en Andalucía de los inmigrantes procedentes de países menos desarrollados. Basándonos en datos de una reciente encuesta representativa, llevamos a cabo un examen pormenorizado de las situaciones de ausencia de vivienda digna en esta población, haciendo especial hincapié en establecer definiciones claras e indicadores transparentes. Los resultados confirman la existencia de una situación residencial gravemente deficiente de una proporción importante de los inmigrantes asentados en zonas de agricultura intensiva, sobre todo en la provincia de Almería. Sin embargo, a diferencia de otros estudios, concluimos que aproximadamente cuatro de cada cinco inmigrantes asentados en Andalucía disponen de una vivienda digna.

    In recent years, the Comision Federal de Electricidad (CFE) has developed important hydroelectrical power projects in Mexico. Most of them are located in the Santiago River Hydrological System in Nayarit, Mexico. A total of 27 projects with a capacity of 4,300 MW are considered but only 32% of them have been carried out. One of the most ambitious projects that continue in process of construction is the Hydroelectrical Plant La Yesca. This project will conclude in late 2012 and consists of two electric generators of 375 MW, 17 kV. It will be second in power and the third in electrical generation at the system. According to national and international standards, a set of static and dynamic tests must be performed in these generators before commissioning, to ensure their proper operation. Winding stator high voltage endurance test, three phase sudden short circuit test and energy efficiency calculation are some of the most important tests to be performed in a new electrical generator. These tests are difficult to perform on-site due to the equipment capacity required, so very few companies in the world can conduct them. In Mexico no one has the necessary infrastructure for testing in high capacity hydroelectric generators such as those from La Yesca, so the Laboratorio de Pruebas a Equipos y Materiales (LAPEM) has invested in projects to improve this project in order to meet the needs of the Mexican electricity sector. This paper is a description of the systems developed for the calculation of electrical parameters and energy efficiency for this class of generators.

First of all, stress the importance of neighbourhoods for individual life outcomes, by way of their relationship with other relevant spaces of socialization and with social exclusion processes. Secondly, measure immigrants’ residential segregation in Madrid’s Metropolitan Area, in four of the five dimensions proposed by Denton and Massey (1988, together with other measures less frequently used.

    El siguiente artículo se propone tres objetivos. En primer lugar, mostrar la relevancia del lugar de residencia para el desarrollo vital de sus habitantes a través de su relación con los demás espacios de socialización y con los procesos de exclusión social. En segundo lugar, medir la segregación residencial de los extranjeros en el área metropolitana de Madrid en cuatro de las cinco dimensiones propuestas por Denton y Massey (1988, además de utilizar otras medidas menos comunes en la literatura y una nueva medida basada en el índice de disimilitud. Por último, identificar las características de los grupos de extranjeros que se encuentran asociadas a la segregación residencial. En concreto, pretendo averiguar si la segregación urbana está asociada con la situación económica y los rasgos culturales de la población extranjera. El trabajo analiza la distribución residencial de 46 nacionalidades y demuestra que tanto los aspectos culturales como económicos están asociados con la segregación residencial, si bien el trabajo no es capaz de determinar con precisión los mecanismos causales que se esconden detrás de estas correlaciones.

El propósito del estudio fue analizar los efectos que genera el turismo residencial en Ixtapan de la Sal a fin de conocer de manera puntual la incidencia en el desarrollo turístico de este destino. El método aplicado en este trabajo, fue el clínico y se empleó con la finalidad de conocer la situación actual del turismo residencial. Así también, con el método deductivo emanado de la revisión teórica de la propuesta de Daniel Hiernaux en su obra Segundas Residencias fue posible lograr confrontar su teoría con los datos recogidos en campo. A partir de la década de los cuarenta, el turismo en México ha presentado distintas modalidades: el turismo de sol y playa; el turismo religioso o el ecoturismo; particularmente, el turismo residencial es una tendencia de reciente auge, práctica aún cuestionada como modalidad turística por no hacer uso de los servicios de alojamiento hotelero como lo hace el turismo convencional, pero que tiene repercusiones importantes en las comunidades anfitrionas, como es el caso de estudio.

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

    A study is performed on the impact that the introduction of the electric vehicle (EV) would have in the environmental pollution of the metropolitan area of Mexico City (MAMC) for different penetration scenarios of this technology and the costs of the electric vehicle is analyzed and compared with its counterpart, the gasoline vehicle. The associated emissions of a fleet formed of EV and internal combustion engine vehicles (ICEV) were determined and the emissions reduction of the contaminants considered in the period 1995-2010 produced was analyzed. It was found that the introduction of EV could importantly reduce the carbon monoxide, methane and carbon dioxide and marginally the nitrogen oxides. It was determined that if the EV is massively produced its total cost for its entire useful life would be comparable to the cost of the ICEV.

    Full Text Available Os serviços residenciais terapêuticos surgem no contexto da reforma psiquiátrica brasileira como um avanço à política de desinstitucionalização, e como serviços essenciais para superação das práticas tutelares, próprias do modelo manicomial, pois possibilita espaços de cuidado, acolhida e moradia digna para pessoas com perdas ou comprometimento dos vínculos familiares e sociais, devido a internações psiquiátricas. O artigo objetiva conhecer a rede de sociabilidade dos usuários do serviço residencial terapêutico de Alegrete/RS, a partir de um estudo de caso. Trata-se de um recorte da pesquisa Redes que Reabilitam - avaliando experiências inovadoras em composição de redes de atenção psicossocial. Utilizou-se dados das entrevistas semiestruturadas com os seis trabalhadores do serviço. Assim, foi possível observar que este serviço apresenta experiência singular e inovadora, construindo saídas para o desafio de aproximar pessoas com extensos períodos de internação psiquiátricas a seus familiares, à comunidade e à vida da cidade, rompendo com a segregação a que estavam submetidos. As aprendizagens de moradores e trabalhadores na construção do SRT demonstram potencialidades para concretizar a reinserção cidadã dos portadores de sofrimento mental à sociedade.

    Full Text Available En las actuales sociedades europeas envejecidas, los comportamientos residenciales de las personas de edad están adquiriendo una importancia creciente. En este artículo se exploran las relaciones causales entre la biografía migratoria previa y las pautas residenciales adoptadas tras los 55 años, usando Event History Analysis. Los resultados demuestran que el lugar de nacimiento marca la trayectoria migratoria posterior de los individuos, llegando a afectar incluso al comportamiento residencial en la vejez. La existencia de migraciones previas, el hábitat de residencia, así como la duración del período sedentario, ejercen también una importante influencia sobre la decisión de movilidad en la vejez. Finalmente, se demuestra que la reducción de la movilidad entre las generaciones de mayores más recientes es un efecto de su biografía migratoria previa. Las trayectorias migratorias protagonizadas por los individuos a lo largo de su vida, joven y adulta, se revelan más decisivas respecto a los comportamientos residenciales en la vejez que las circunstancias coyunturales. Por ello, posibles cambios en las biografías migratorias de las generaciones más jóvenes podrían traducirse en cambios en los niveles de movilidad en la vejez, independientemente de las circunstancias coyunturales. A este respecto se pueden observar diferencias por género, mostrándose las mujeres más vulnerables frente a las circunstancias históricas que los hombres.

    Full Text Available De forma paralela al proceso de expansión suburbana en las ciudades latinoamericanas y, en especial, en Santiago de Chile, se observa un movimiento residencial y espacial centrípeto, que pone en valor los atributos de localización de sus espacios centrales y que lleva a plantear la tesis del regreso a la ciudad consolidada. Dicho movimiento se inicia en los años noventa, cuando el municipio de Santiago lleva a cabo el Plan de Repoblamiento cuyos objetivos se orientaron a la generación de una oferta de vivienda nueva en zonas de deterioro y en barrios consolidados y bien conectados al resto del sistema metropolitano. A esto último, se sumaron obras de mejoramiento vial y urbano, el arribo de oferta cultural y comercial y, por sobre todo, la llegada de nuevos habitantes urbanos, específicamente jóvenes y adultos profesionales y técnicos que posicionaron y consolidaron al centro como uno de los espacios residenciales más dinámicos.Parallel to the process of suburban expansion in the Latin American cities and especially in Santiago of Chile a centrifugal residential and spatial movement is observed. This movement values the attributes of location of central spaces, thus raising the thesis of the return of the consolidated city. This movement begins in the nineties, when the municipality of Santiago carries out a Repopulation Plan that was oriented to the generation of a supply of new housing in of deteriorated zones and in consolidated and well connected districts. Works of road and urban improvement, the arrival of cultural and commercial supply and the arrival of new urban inhabitants --specifically young and adult professionals and technicians, who positioned and consolidated the downtown area as one of the more dynamic residential spaces-were added.

    Within the framework of assessing the state of the environment in Lebanon, this chapter describes primary energy demand, the electricity generating sector and environmental impacts arising from the energy sector.Apart from hydropower and traditional energy sources, which together represent 1.7% of energy consumption, all energy in Lebanon derives from imported petroleum products and some coal.Tables present the imports of different petroleum products (Gasoil, Kerosene, fuel oil, coal etc...), their use, the energy balance and demand.Energy pricing and pricing policies, formal and informal electricity generations in Lebanon are described emphasized by tables. The main environmental impacts are briefly summarized. Thermal power stations give rise to emissions of Sulphur dioxide (SO 2 ), particulates, oxides of nitrogen (NO x ) and CO/CO 2 from combustion of primary fuel informally generated power from both industry and domestic consumption produce particulate materials and emissions of NO x and SO 2 projected emissions of SO 2 from the power sector with the present generating capacity and with the new combined cycle power plants in operation are shown. Other environmental impacts are described. Recommendations for supply and environment policy are presented

  20. 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

    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

    Full Text Available Resumen El área metropolitana de La Plata representa el 1,6% de las viviendas de la Argentina. A partir del análisis del reciclado de una vivienda se construyen indicadores básicos con el fin de proponer una metodología que facilite la extrapolación, a nivel regional, del impacto que causaría un programa de eficiencia energética en viviendas. Se exponen desde el nivel micro a macro los resultados obtenidos en un contexto de carestía energética y recurrentes crisis en la oferta de combustibles y electricidad en la Argentina. La mejora en la resistencia térmica de muros y techos en todo el parque residencial de La Plata conllevaría a una reducción del 12% de la energía consumida en calefacción, y un ahorro de 30.000 TEP/año. Se concluye que la incidencia que implica la colocación de aislación adicional respecto del costo de la construcción justifica su uso, resolviendo parcialmente la falta de combustibles en el país, reduciendo gastos fijos en la vivienda, otorgando confort térmico a los usuarios y generando reactivación del sector de la construcción.

    Full Text Available Ecuador, debido a su ubicación geográfica, cuenta con irradiación solar de adecuada intensidad y duración para aplicaciones energéticas. Esta energía puede ser aprovechada para la producción de energía eléctrica a nivel residencial e industrial resultando ser, bajo ciertas condiciones, más económica que la consumida desde la red eléctrica nacional. En este artículo, con base a los resultados obtenidos usando RETScreen, se muestran las características que deberán tener el sistema fotovoltaico residencial, su producción eléctrica y análisis económico para el retorno de la inversión inicial. tres hipótesis son planteadas tomando en consideración: un net-metering con la empresa eléctrica de distribución, el consumo eléctrico medio mensual de clientes residenciales en la ciudad de Guayaquil, y la irradiación solar de la localidad. Además, para los cálculos de simulación se toma en cuenta un costo menor de cada kWh producido por el sistema fotovoltaico en referencia al ofertado por la empresa de distribución eléctrica y así analizar la factibilidad económica de la Grid Parity en la ciudad de estudio.

    Full Text Available El objetivo del presente trabajo consistió en examinar el ajuste social y escolar de jóvenes que habían sufrido maltrato en la infancia y se encontraban en situación de acogimiento residencial. Además, pretendíamos comprobar si existían diferencias entre los sujetos sometidos a distintas situaciones de desprotección infantil. En el estudio participaron 318 jóvenes residentes en la Comunidad Autónoma del País Vasco de edades comprendidas entre los 13 y los 18 años (M = 15.35, DT = 1.68 pertenecientes a tres colectivos. El primero de ellos estaba constituido por 69 jóvenes (31 mujeres y 38 varones víctimas de maltrato infantil que se hallaban bajo una medida de protección de acogimiento residencial. El segundo grupo estaba formado por 75 jóvenes (29 mujeres y 46 varones víctimas de maltrato infantil que se encontraban en situación de riesgo de desamparo. Por último, el tercer grupo estaba constituido por 174 jóvenes (95 mujeres y 79 varones que no habían sufrido maltrato. Los resultados pusieron de manifiesto que, independientemente de la situación de desprotección infantil en la que se encontrasen, los jóvenes víctimas de maltrato infantil mostraban mayores dificultades de adaptación social y escolar que los jóvenes que no habían sufrido maltrato en la infancia.

    Full Text Available La medición de la segregación residencial de población extranjera, tradicionalmente se ha cen-trado en analizar su localización, distribución y concentración en el espacio urbano. Este artículo se centra en analizar el umbral de segregación a partir del cual sería necesaria la intervención social en aras de una correcta gestión de la diversidad étnica y cultural. Para ello, a través de una metodología basada en el análisis de las actitudes hacia el extranjero, analizamos la relación entre la segregación y la xenofobia. Consideramos que en el origen de la segregación residencial de la población extranjera, además de elementos económicos y residenciales, se puede encontrar un trasfondo de subjetividad socio-espacial, estrechamente relacionado con la aparición de la xeno-fobia. Esto resulta crucial para analizar la manera en que los ciudadanos generan su imagen sobre las zonas segregadas, ya que dicha construcción social determina el inicio o desarrollo del proce-so de segregación. En el caso de Sevilla, esta metodología ha servido para identificar tres ámbitos y dimensiones diferenciadas de segregación. Barrios donde el extranjero está claramente segre-gado, barrios marginalizados y segregados, así como zonas donde el extranjero resulta invisible.

    The deregulation and restructuring undergone by the electrical industry, as well as the tendency at world-wide level of reorganization in generation, transmission and distribution units has brought about, as a consequence, drastic changes in the operation of the electric power systems. The difficulties to construct new transmission power lines and the continuous increase in the electricity consumption are forcing more and more to operate the electric power systems every time nearer their safety limits. Nevertheless, to assure the system reliability without mattering what so plaintiff is the operating condition is a requirement that the electrical companies must satisfy. This panorama has motivated and impelled the use of new technologies for the critical indicators the monitoring that allow the electrical companies to guarantee the system safe operation. In this paper a methodology for the location of Fasorial Measurement Units, better known as FMU for the monitoring of the critical oscillation modes in the electric power systems is presented.

    One principle that the electricity sector must fulfil is to simultaneously guarantee generation free entrance, new and old demand supply and a harmonic network development. This development is contained in the grid planning, a process assumed by a neutral institution apart from the grid or the interests of the market agents: In the case of Spain the ministry. The development of such planning, the investment to be built, are limited by the physical network and formal structure and by how the retribution is designed. In this article there is an evaluation of the problems related to develop the network planning in a competitive environment and also some proposals are suggested. (Author)

    In the context of the segregation of the product (kWh) and the service of electricity transport and distribution, the establishment of a retributive model for distribution becomes especially relevant, even fundamental within a free market for generators and consumers. The liberalization of distribution is established by means of the greed access of third parties to the network. Electricity distribution in Spain has traditionally be badly remunerated and incomes have not been sufficient to support the segregation of activities. These inequalities should be resolved by means of a retribution model for distribution that reflects the real cost of this activity and which contemplates the specific characteristics of the different zones of the market.

    The constant growth of the Electric Power Systems derived from the increase in the world-wide demand of energy, has brought as a consequence a greater complexity in the operation and control of the power nets. One of the most affected tasks by this situation is the operation of electrical systems against the presence of faults, where the first task to realize is, on the part of the operational personnel of the network, the rapid fault site location within the system. In the present paper the problem of the diagnose location of electrical faults in power systems is approached, from the point of view of the operators of the energy control centers of an electric company. The objective of this thesis work is to describe a methodology of operational analysis of protections, as a bases for the development of a system of diagnosis systems for faults location, that allows to consider the possible fault sites within the system as well as a justification of the operation of protections in face of a disturbance as a support to the operators of the Energy Control centers. The methodology is designed to use different information types, discreet, continuous and controls. Nevertheless, in the development of the present stage of the proposed methodology use is made exclusively of the discreet information of the conditions of breakers and operation of relays, as well as of the connectivity of the network elements. The analysis methodology consists in determining the network elements where the fault could have occurred, using the protections coverage areas associated to the operated circuit breakers. Later, these fault alternatives become ordained in descendent form of possibility using classification indexes and analyses based on fuzzy logic.

This method does not have to form the curve of incremental equivalent cost, with which a great deal of memory storage and execution time are saved. [Spanish] Se presenta un metodo para resolver el problema de asignacion de unidades termoelectricas en sistemas electricos de potencia de gran escala. El problema consiste en determinar cuales unidades generadoras deberan ser programadas para entrar o salir de operacion durante los intervalos de horizonte de planeacion, de tal forma que se satisfagan a minimo costo, y en forma confiable la demanda pronosticada de potencia electrica y las restricciones fisicas y operativas de los componentes del sistema de potencia. El metodo esta compuesto por dos etapas: la primera etapa encuentra una solucion inicial factible de unidades termo por medio de metodos heuristicos. La segunda etapa produce una solucion a partir de un estado de asignacion inicial factible. El costo de operacion se reduce aplicando programacion dinamica en aproximaciones sucesivas, de tal forma que el producto de cada interaccion constituye el estado de asignacion de menor costo encontrado hasta esa etapa. El rango de busqueda para la solucion optima es reducido aplicando tecnicas de relajacion lagrangeana para seleccionar unicamente las unidades que tienen el mayor potencial de reducir el costo de operacion. El algoritmo es validado utilizando un sistema representativo del sistema interconectado nacional que consta de 108 unidades termoelectricas agrupadas en 7 grupos de generacion, para un horizonte de planeacion de una semana dividido en intervalos horarios, conteniendo 18,144 variables discretas, 18,144 variables continuas y 39,024 restricciones.

Este plan, llevado a cabo por la Comunidad de Madrid, tiene como objetivo incre- mentar las habilidades, conocimientos y actitudes que favorezcan el proceso de autonomía y emancipación. El presente artículo se sitúa en el momento inmediatamente anterior a la salida del centro de protección, por lo que reú- ne información relevante sobre los riesgos y las oportunidades del tránsito a la vida adulta de los jóvenes extutelados, en concreto, aquellos relacionados con la familia de origen. Se han elaborado dos cuestionarios; uno, dirigido a los jóvenes y, otro, a los educadores de los centros. Han participado 105 profesionales de la intervención socioeducativa y 106 jóvenes de 54 recursos de acogimiento residencial de la Dirección General de la Familia y el Menor de la Comunidad de Madrid. Los resultados plantean una contradicción entre la realidad familiar con ̄ictiva de estos jóvenes y las expectativas de un trán- sito a la vida adulta precisamente con esa familia como principal referente y recurso. Se trata de un aspecto problemático y contradictorio dado que la intervención con las familias de los jóvenes resulta compleja, la participación y el compromiso familiar con el proceso de emancipación son escasos y, en general, son valorados negativamente por los profesionales, llegando a ser considerados como un obstáculo para la transición a la vida adulta de algu- nos jóvenes.

    Full Text Available El objetivo del trabajo consiste en estudiar la evolución del consumo agregado de energía eléctrica residencial en la Zona Metropolitana de Monterrey, Nuevo León, México. Ello, debido a que dicha metrópoli ha experimentado niveles de consumo muy por encima de la media nacional. En este sentido, la idea principal consiste en cuantificar el impacto generado por el crecimiento de los usuarios, la sensibilidad del consumo ante variaciones en el precio del servicio y de un indicador nacional de la actividad económica como medida proxy del ingreso de la zona ante la ausencia de un indicador regional. Para ello, se estima una función de demanda al estilo Cobb-Douglas con series de tiempo de 1993 al 2010 en frecuencia mensual y el enfoque de cointegración de Engel-Granger. Las estimaciones realizadas nos indican que un incremento porcentual del número de hogares incrementa en 0.61 por ciento el consumo. De la misma forma, un incremento porcentual el ingreso incrementa en 0.88 por ciento el consumo. En tanto que incrementos en el precio del servicio reducen la demanda en 0.63 por ciento en el largo plazo.

    At present, PEMEX is using new artificial pumping systems for the production of oil, specifically the Electro Centrifugal Pumping system (ECP). Nevertheless, during the operation of the (ECP) system problems by the failure of their electrical components have appeared, mainly of the equipment installed within the well. The faults have resulted in an increased cost for the diminution in the production and the maintenance cost of the remedial work. The maintenance personnel have procedures to perform verification tests of the conditions of the bottom electrical equipment. But, in the case of an electrical failure of the equipment, its location cannot be determined, since they are installed at 3,600 m from the production wellhead. In accordance with the former, the Instituto de Investigaciones Electricas proposed the application of the reflectometry technique in the time domain, to complement the maintenance procedures. This technique is a very useful diagnosis tool of the electrical equipment, which helps in the decision making of the maneuvers of preventive and corrective maintenance to be followed, with the consequent saving of resources. [Spanish] Actualmente, PEMEX esta utilizando nuevos sistemas artificiales de bombeo para la produccion de petroleo, en especifico el Sistema de Bombeo Electrocentrifugo (BEC).

Sob a ótica da sustentabilidade do espaço público, foram analisadas, no âmbito do Projeto CNPq/FAU/UNB "Urbanismo sustentável para reabilitação de áreas degradadas", quarenta e duas (42 superquadras, vinte e duas (22 na Asa Norte e vinte (20 na Asa Sul, das 120 existentes. A partir do exame do desempenho das estruturas urbanas e da relação entre os atributos do espaço urbano e o microclima, especialmente a relação W/H e os cânions urbanos, detectamos, a partir dos dados obtidos por medições e simulações, a formação de ilha de calor no espaço residencial. Os edifícios construídos a partir dos anos 90 estão alterando o microclima local. Edifícios mais largos, a descaracterização dos pilotis, a presença de apartamentos não vazados, de sacadas fechadas, a falta de brises, as fachadas espelhadas, e as ávores ornamentais que não fornecem sombra, todos eles elementos permitidos por lei, prejudicam o fluxo do vento e aumentam temperatura do ar.

    Full Text Available This article describes the thorough and minute conception of a multi-family building, where the presiding idea of achieving the feeling of individual separated homes has been created by the treatment of exteriors —landscaping, terraces, etc.— by the privacy- oriented layout of each housing unit and by the provision of services adequate to the high class and quality desired in this project. The carpark is collective —three carstalls to every unit— the servants quarters are arranged in independent bungalows, and the complex is provided with an ample garden, swimming pools and concierge accomodations. The materials used both in interiors and exteriors are conventional but of high quality, deserving mention the gracious variable planes designed in plan and elevation, and the chromatic reververation of roofing tiles, all of which confer this complex a unique, original and clearly distinctive personality.

    Se describe en este artículo la concepción extraordinariamente cuidada de un edificio multifamiliar con la idea fundamental de lograr una sensación de viviendas aisladas, tanto en el tratamiento exterior —jardinería, terrazas, etc.—, como en la privacidad de cada unidad residencial, con 400 m2 construidos, y distribución y servicios adecuados a la categoría de gran nobleza prevista en el proyecto. Hay un aparcamiento colectivo —con tres plazas por vivienda—, unos bungalows independientes para el servicio, amplio jardín circundante, piscinas y vivienda del portero. Los materiales utilizados en el interior y exterior son tradicionales y de gran calidad, destacando la graciosa movilidad de plantas y alzados y la vibración cromática de las tejas de la cubierta, todo lo cual confiere al complejo una fisonomía característica, original y francamente distintiva.

Estos cambios parecen estar afectando a la mayoría de las ciudades latinoamericanas. Están vinculados con las políticas de liberalización de los mercados de suelo y con los procesos de globalización económica y cultural de las últimas décadas. En el artículo se entrega información empírica sobre los efectos de estos cambios en tres ciudades chilenas (Santiago, Valparaíso, Concepción; y se discute teóricamente la relación entre desigualdad social y segregación espacial, rechazando el enfoque usual que ve a la segunda como un mero reflejo en el espacio de la primeraThe pattern of residential segregation is undergoing two crucial changes in Chilean cities: its geographical scale is shifting, and segregation’s malignancy is increasing. Seemingly, these changes are affecting most of Latin American cities.

Hasta el momento se desconoce cuál será el impacto del envejecimiento demográfico en las sociedades con menor afluencia de recursos económicos y, aún más, en contextos de pobreza. Según los estudios de historia demográfica, una de las consecuencias del envejecimiento poblacional es el cambio en las modalidades y configuraciones de los arreglos familiares en los que residen las personas adultas mayores. En este artículo se analizan comparativamente los tipos de hogar y allegamiento generacional de convivencia de las personas mayores en México y Argentina y, a su vez, en las regiones que conforman cada uno de estos países. Se contrasta el tipo de hogar, las modalidades de allegamiento generacional y el nivel de envejecimiento demográfico regional con las características de las poblaciones de adultos mayores seleccionadas: a pobreza por ingresos, b cobertura previsional y c cobertura de salud. Asimismo, se elaboró un modelo logístico multinomial para estimar la probabilidad relativa de residir en distintos tipos de hogar considerando como variables independientes: a el sexo, b la edad, c el nivel educativo y d las regiones de residencia. El propósito del análisis comparado es documentar el impacto del envejecimiento demográfico y del desarrollo económico y social de las regiones en las modalidades de allegamiento residencial de las personas adultas mayores en dos países de América Latina y el Caribe.

    Full Text Available El proceso habitacional chileno ha priorizado un enfoque cuantitativo en la producción de las viviendas sociales, relegando aspectos de orden cualitativo a un segundo plano, ante la urgencia de asumir el déficit habitacional del país. De todos modos, la importancia de mejorar la calidad de vida en los barrios de menores recursos, se ha transformado en un objetivo declarado, debido tanto a la mala calidad de los productos ofrecidos por los programas estatales, como a la incapacidad de responder a las necesidades de la población. Basada en una investigación, que pretende desarrollar un enfoque integral de la calidad residencial, este artículo, presenta en primer lugar una breve descripción del enfoque habitacional implementado en el país. Luego, se explica el marco conceptual de la calidad residencial y la definición de una propuesta metodológica ad hoc, la cual a partir del análisis de los resultados de la investigación, se traduciría en propuestas de diseño y normativas mejoradas.

    In this work it is presented the pattern of an active filter of current and their implementation in the program Simulink of MatLab to reduce the content of harmonics generated for different non lineal load. For the active filter of current they were developed each one of the stages that integrate it, from the obtaining of references, the control block and the stage of power. For the obtaining of references, the reactivates instantaneous power theory was used. For the control of the shots of the IGBT's a control knot was used based on a hysteresis band and for the stage of power, an inversor complete bridge was used with a capacitor like source of direct voltage. To analyze the behavior of the active filter, a real industrial electric system was modeled with a lineal load RL and two non lineal load, a using a converter to diodes of 6 pulses and other a working of a machine of dc with a converter to tiristores of 6 pulses. These configurations were used because their content of harmonicas is high. To this system was integrated the active filter modeled in the exit of the non lineal load to avoid that the harmonic components generated by the loads non lineal distortions the current signals. The current signals, voltage signals, power flow, power factor and the harmonic components that circulate in the industrial electric system were analyzed.

    Luiz Cesar de Queiroz Ribeiro

    Full Text Available O presente artigo objetiva analisar a relação entre vulnerabilidade social e as tendências à segmentação e segregação residencial em nossas grandes cidades. Tem-se como pressuposto que, em todas as sociedades capitalistas, existiram diferentes sistemas de gestão dos riscos à reprodução material e à coesão social. Nas metrópoles brasileiras, a vulnerabilidade social decorre da crise de um regime de bem-estar social dual, fundado a partir da combinação das livres forças de mercado e da mobilização das estruturas familiar-comunitárias, particularidades do nosso desenvolvimento capitalista. Escolhemos como indicador de vulnerabilidade social os segmentos da população de 4 a 24 anos, que correspondem a vários ciclos de socialização e de aquisição dos recursos necessários à reprodução e à integração sociais, cuja situação de vulnerabilidade se diferencia de acordo com a importância da família, da escola e (ou do mercado na reprodução social desse grupo. Os resultados indicam que, independentemente da localização da moradia, se no centro ou na periferia das metrópoles, se nas regiões mais favorecidas ou não, o contexto social do "bairro" onde há pouco capital social na forma de relações estáveis com o mercado de trabalho aumenta os riscos de que essa população esteja em situação de vulnerabilidade. Portanto, é possível pensar num padrão de sociabilidade marcado por um isolamento social com baixo grau de exposição aos ativos que permitem superar essa situação que, ao mesmo tempo, é marcada pela instabilidade da vida social.

  16. Torus sector handling system

    Grisham, D.L.

    1981-01-01

    A remote handling system is proposed for moving a torus sector of the accelerator from under the cryostat to a point where it can be handled by a crane and for the reverse process for a new sector. Equipment recommendations are presented, as well as possible alignment schemes. Some general comments about future remote-handling methods and the present capabilities of existing systems will also be included. The specific task to be addressed is the removal and replacement of a 425 to 450 ton torus sector. This requires a horizontal movement of approx. 10 m from a normal operating position to a point where its further transport can be accomplished by more conventional means (crane or floor transporter). The same horizontal movement is required for reinstallation, but a positional tolerance of 2 cm is required to allow reasonable fit-up for the vacuum seal from the radial frames to the torus sector. Since the sectors are not only heavy but rather tall and narrow, the transport system must provide a safe, stable, and repeatable method fo sector movement. This limited study indicates that the LAMPF-based method of transporting torus sectors offers a proven method of moving heavy items. In addition, the present state of the art in remote equipment is adequate for FED maintenance

    The energy sector is a key driver of the economic pillar of Vision 2030. As the economy grows, urbanization intensifies and incomes increase, corporate and household demand for energy also rises. To meet this growth in demand for energy, the sector needs to increase investments and diversify into more sources of energy such as geothermal and wind power. It is therefore critical that focus is directed towards development and sustainability of the energy sector to ensure delivery of least cost power that will improve Kenya's competitiveness and achieve the Vision 2030 objective of 10% average annual economic growth.

Las mujeres en España presentan tasas de desempleo, trabajo temporal y a tiempo parcial mucho mayores que los hombres. Además, las condiciones de acceso al mercado de trabajo y las condiciones en las que éste se desempeña están también muy relacionadas con la clase social. Las mujeres cubren la escasez de servicios públicos destinados al cuidado de las criaturas pequeñas y de las personas mayores o dependientes, y realizan una labor de cuidadoras informales sin reconocimiento social, lo cual les impide el acceso a un puesto de trabajo o su mantenimiento y limita de forma decisiva las posibilidades de desarrollo y progreso profesional. Todo ello indica una clara diferencia con respecto a los hombres en cuanto a la frecuencia de contratos temporales y de tiempo parcial, así como en la segregación laboral, tanto horizontal como vertical. Estos aspectos de segregación son más evidentes en las mujeres de clases sociales menos privilegiadas, en las que se concentran las peores condiciones de acceso al mercado laboral y de trabajo. En España es imprescindible llevar a cabo políticas que ofrezcan servicios que permitan compatibilizar la vida laboral y familiar en condiciones de mayor equidad, tanto en razón de género como de clase social.In the last 25 years, the production sector in Spain has undergone important changes. Among these changes, the important growth of the services sector at the expense of the primary sector, the increasing flexibility of the labour market, and the rise in the female workforce could be considered as the most relevant ones.

    The energy sector in Italy, as in Europe and in many other areas of the world, is undergoing rapid and profound changes. The 1986 ratification of the European Single Act was intended to create a European internal market, where circulation of people, capital, goods, and services would reach the highest possible liberalization. In 1988, in the document The Energy Internal Market, the European Union (EU) commission stressed the need for creation of an internal energy market--free of obstacles--to increase security of supply, to reduce costs, and to strengthen the competitiveness of the European economic system. In 1990, the Community Council adopted directives to implement the EU energy sector. This article describes Italy's role as part of the EU energy sector. It covers the following topics: the Italian energy sector; electricity vs gas transportation; project finance; recent developments advance Italian power industry; specifying powerplant components -- Italian stype; buyers' guide to Italian equipment, services

    Determination of electrical losses is one of the most important tasks for any enterprise dedicated to generation, transmission, transformation and/or distribution of electric energy. Any enterprise dedicated to these activities does continuously energy balances in order to estimate whole electrical losses of specific processes. However, it is necessary to classify the whole electrical losses into technical and non-technical losses. This paper presents a proposal for estimating technical and non-technical losses in an electrical power system. [Spanish] La determinacion de las perdidas de energia electrica es una de las labores mas importantes en cualquier empresa dedicada a la generacion, transmision, transformacion y/o distribucion de energia electrica. Es indudable que toda empresa dedicada a cualquiera de las actividades mencionadas anteriormente realiza periodicamente balances de energia que permiten estimar el valor de las perdidas totales de energia del proceso considerado. No obstante, para poder realizar un mejor analisis de la problematica de las perdidas de energia, es necesario separar el valor total de perdidas obtenido mediante un balance de energia, en perdidas tecnicas y perdidas no tecnicas. El presente trabajo presenta una propuesta para la estimacion de perdidas tecnicas y no tecnicas en un sistema electrico de potencia.

    Full Text Available Con relativa independencia de su nivel social, edad y sexo, los residentes de las ciudades chilenas de Santiago, Antofagasta y Temuco muestran una significativa disposición a la integración residencial con personas de otra condición social. Sin embargo, dicha valoración de la integración enfrenta, por una parte, obstáculos y temores concretos (como el menoscabo a las plusvalías o respecto de la formación de los hijos que dificultan que se materialice en barrios menos segregados; y por otra, actitudes y conductas "clasistas". En términos prácticos, esta cultura urbana tensionada y ambivalente, junto a la relativa asimetría que presenta la segregación residencial entre sus dimensiones principales en el medio latinoamericano y a la prevalencia de una mezcla de indiferencia y tolerancia en la relación con el "otro", propia de las ciudades modernas, otorgarían viabilidad cultural a futuras políticas de reducción de la segregación.With relative independence of their social level, age or sex, the residents of the Chilean cities of Santiago, Antofagasta and Temuco show a significant disposition to residential integration with people of different social conditions. However, this positive evaluation of integration is confronted by concrete obstacles and fears (like the possible damage to the value of their properties or to the education of their children that make the materialization of less segregated neighborhoods harder, on the one hand, and "classist" attitudes and conducts, on the other. In practical terms, this ambivalent urban culture, together with a relative assymetry of residential segregation are the main dimensions in the Latin American context. These, together with a mixture of indifference and tolerance towards the "other", which are characteristic of modern cities, give cultural viability to future policies for the reduction of segregation.

  19. Waste management. Sector 6

    International Nuclear Information System (INIS)

    1994-01-01

    The waste management section of this report deals with two sectors: land disposal of solid waste and wastewater treatment. It provides background information on the type of emissions that contribute to the greenhouse gases from these two sectors, presents both sector current status in Lebanon, describes the methodology followed to estimate the corresponding emissions, and presents the results obtained regarding greenhouse emissions. The total methane emissions from solid waste disposal on land are 42.804 Gg approximately. There are no emissions from wastewater and industrial handling systems because, for the target year 1994, there was no treatment facilities in Lebanon. The wastewater (municipal, commercial and industrial) was directly discharged into the sea, rivers, ravines or septic tanks which indicate that methane or nitrous oxide emissions are significant if not nonexistent. Note that this situation will change in the future as treatment plants are being constructed around the country and are expected to come into operation by the year 2000

Esta situación parece estar ya establecida hace 1700 anos AP. Algunas de las propiedades del mismo sugieren una importante concentración de poblaciones humanas en el área, con reducida movilidad residencial e intensificación en la explotación de los recursos de alto ranking y una especial concentración en la explotación de los recursos fluviales. La fuerte diversidad estilística que se observa en los patrones de decoración de la alfarería y en el tratamiento de la muerte, son coherentes con la existencia de una compleja y variada identidad social, cuya dinámica posiblemente estuvo influenciada por conductas densodependientes que se acrecentaron aun mas por el arribo de grupos horticultores amazónicos.

    Santolaria, Encarna; Fernández, Alberto; Daponte, Antonio; Aguilera, I

    2004-05-01

    In the last 25 years, the production sector in Spain has undergone important changes. Among these changes, the important growth of the services sector at the expense of the primary sector, the increasing flexibility of the labour market, and the rise in the female workforce could be considered as the most relevant ones. Spanish women have higher rates of unemployment, temporary jobs and part time contracts than Spanish men. Moreover, job access and work conditions are highly related to gender and social class. Because women are forced to compensate for the scarcity of social services for caring for young children and for dependent elderly, they become informal and socially unrecognised caregivers, preventing them from getting or holding a job, and significantly limiting their opportunities for professional development. These social conditions are closely related with the fact that work conditions for women involve higher temporality rates and shorter contracts than those of men, given the sectors and jobs in which they tend to work (due to segregation). Similarly, workers of the less privileged social classes have poorer work conditions. Thus, women of the lower income class are mainly suffering the worst job contracts and the poorest work conditions. More social services are needed to make it possible to attend to family needs and still be able to access and maintain a job contract. Policies tending to conciliate labour and family life are indispensable and should incorporate measures to equally distribute the house keeping activities between women and men.

    Full Text Available This study aimed to estimate the watershed runoff caused by extreme events that often result in the flooding of urban areas. The runoff of a residential area in the city of Guaratinguetá, São Paulo, Brazil was estimated using the Curve-Number method proposed by USDA-NRCS. The study also investigated current land use and land cover conditions, impermeable areas with pasture and indications of the reforestation of those areas. Maps and satellite images of Residential Riverside I Neighborhood were used to characterize the area. In addition to characterizing land use and land cover, the definition of the soil type infiltration capacity, the maximum local rainfall, and the type and quality of the drainage system were also investigated. The study showed that this neighborhood, developed in 1974, has an area of 792,700 m², a population of 1361 inhabitants, and a sloping area covered with degraded pasture (Guaratinguetá-Piagui Peak located in front of the residential area. The residential area is located in a flat area near the Paraiba do Sul River, and has a poor drainage system with concrete pipes, mostly 0.60 m in diameter, with several openings that capture water and sediments from the adjacent sloping area. The Low Impact Development (LID system appears to be a viable solution for this neighborhood drainage system. It can be concluded that the drainage system of the Guaratinguetá Riverside I Neighborhood has all of the conditions and characteristics that make it suitable for the implementation of a low impact urban drainage system. Reforestation of Guaratinguetá-Piagui Peak can reduce the basin’s runoff by 50% and minimize flooding problems in the Beira Rio neighborhood.

    The general characteristics of a planning model for the electrical generation system expansion with risk demarcation criteria, as well as the main results of a representative study case of the Mexican Electrical System is presented. The model is based on a methodology of multiannual optimization for the generation expansion plans determination. In this context, every expansion plan defines the technology type to be installed, as well as the installation year, unit size and its location within a regional electric network. For this purpose, the model considers an interregional representation of the system identifying the necessary reinforcements to the capacity of the interregional connections. It also incorporates a Demarcation of Risk module that considers the uncertainty of the future scenarios of fuels prices to generate a set of expansion plans, among which includes the following: a) For every future of the fuel prices: the plan that diminishes the present value of the total cost (investment plus production). b) The plan that diminishes the economic risk derived from the uncertainty in the future of the fuel prices. c) A subgroup of expansion plans that are located in the efficient borders of decision, under the context of three criteria of interest: the economic risk, the investment cost of and the total cost in the future considered of greater relevance.

    The Cuban oil industry started in 1860 when an oil well was drilled in Matanzas province. About 200 wells were drilled up until 1959. In the past 30 years, the oil industry has become a priority sector; in 1985-1990, about US$500 million were invested in the industry, with increases in exploration and well drilling activity. Recently completed works include pipelines and a supertanker terminal. About 10 million tons of oil are imported annually and local production averages about 800,000 metric tons per year. Most of the oil found in Cuba so far is of the heavy type, as found in western Canada. There are about 10 small and medium-sized oil deposits, mainly located in the north. The most promising oil field is at Varadero, whose characteristics are similar to the Cold Lake field in Alberta. Cuban oil refining capacity is over 7.6 million metric tons per year, and additional capacity is being constructed. All imports of oil industry equipment are conducted via state trading agencies. Export opportunities of interest to Canadian companies are outlined, along with monetary constraints affecting imports to Cuba, financing and export insurance programs available to Canadian companies, and recommendations to Canadian exporters. A list of industry/government contacts is included

    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

    In order to facilitate the answer of the Comision Federal de Electricidad (CFE) to the requests of services of transmission of authorized or potential licensees, this organism devised the construction of matrices of charges that allow in a fast and direct way for specific transactions, to know the charges in which different types of transmission services incur classified by transport levels and by tension levels in which the service is asked for. These tables could be published in the media that might be judged advisable, in order that the applicant licensees have access to a preliminary estimation of the charges for the required services, without the need of going, for one first estimation, directly to the CFE for their calculation. This article presents the results of the development of a calculation tool that allows estimating, in a fast and efficient way, charges for transmission services between regions of the national electrical system.

    Full Text Available The majority of household savings are in the form of bank deposits. It is therefore of interest for credit institutions to tailor their deposit policy for getting finances from non-banking entities and to provide the private sector with the loans that are necessary for investment activities and consumption. This paper deals with the determinants of the saving rate of the private sector of Slovakia. Economic, financial and demographic variables influence savings. Growth of income per capita, private disposable income, elderly dependency ratio, real interest rate and inflation have a positive impact on savings, while increases in public savings indicate a crowding out effect. The inflation rate implies precautionary savings, and dependency ratio savings for bequest. There are also implications for governing institutions deciding on the implementation of appropriate fiscal and monetary operations.

  3. Sector retinitis pigmentosa.

    2005-05-01

    Retinitis pigmentosa (RP) is one of the most common hereditary retinal dystrophies and causes of visual impairment affecting all age groups. The reported incidence varies, but is considered to be between 1 in 3,000 to 1 in 7,000. Sector retinitis pigmentosa is an atypical form of RP that is characterized by regionalized areas of bone spicule pigmentation, usually in the inferior quadrants of the retina. A 57-year-old Hispanic man with a history of previously diagnosed retinitis pigmentosa came to the clinic with a longstanding symptom of decreased vision at night. Bone spicule pigmentation was found in the nasal and inferior quadrants in each eye. He demonstrated superior and temporal visual-field loss corresponding to the areas of the affected retina. Clinical measurements of visual-field loss, best-corrected visual acuity, and ophthalmoscopic appearance have remained stable during the five years the patient has been followed. Sector retinitis pigmentosa is an atypical form of RP that is characterized by bilateral pigmentary retinopathy, usually isolated to the inferior quadrants. The remainder of the retina appears clinically normal, although studies have found functional abnormalities in these areas as well. Sector RP is generally considered a stationary to slowly progressive disease, with subnormal electro-retinogram findings and visual-field defects corresponding to the involved retinal sectors. Management of RP is very difficult because there are no proven methods of treatment. Studies have shown 15,000 IU of vitamin A palmitate per day may slow the progression, though this result is controversial. Low vision rehabilitation, long wavelength pass filters, and pedigree counseling remain the mainstay of management.

    We review recent work on realistic models that break supersymmetry dynamically and give rise to composite quarks and leptons, all in a single sector. These models have a completely natural suppression of flavor-changing neutral currents, and the hierarchy of Yukawa couplings is explained by the dimensionality of composite states. The generic signatures are unification of scalar masses with different quantum numbers at the compositeness scale, and lighter gaugino, Higgsino, and third-generation sfermion masses

  7. Composite Dark Sectors

    We introduce a new paradigm in Composite Dark Sectors, where the full Standard Model (including the Higgs boson) is extended with a strongly-interacting composite sector with global symmetry group G spontaneously broken to H is contained in G. We show that, under well-motivated conditions, the lightest neutral pseudo Nambu-Goldstone bosons are natural dark matter candidates for they are protected by a parity symmetry not even broken in the electroweak phase. These models are characterized by only two free parameters, namely the typical coupling g D and the scale f D of the composite sector, and are therefore very predictive. We consider in detail two minimal scenarios, SU(3)/[SU(2) x U(1)] and [SU(2) 2 x U(1)]/[SU(2) x U(1)], which provide a dynamical realization of the Inert Doublet and Triplet models, respectively. We show that the radiatively-induced potential can be computed in a five-dimensional description with modified boundary conditions with respect to Composite Higgs models. Finally, the dark matter candidates are shown to be compatible, in a large region of the parameter space, with current bounds from dark matter searches as well as electroweak and collider constraints on new resonances.

  8. Private sector participation in power sector in India

    1992-01-01

    The Indian Government is currently thinking of allowing private sector to participate in power sector inviting private sector to generate electricity mainly from coal. The main motivation is resource mobilization from private sector, since the Plan funds are diverted to rural development away from power sector; and yet the massive expansion has to be financed. The paper analyzes the inherent difficulties and contradictions in the Government's proposal, such as co-existence of high cost private power and low cost public power, the potential goal-conflicts of private and public utilities and the constraints in raising finance. It suggests a different model in order to make the privatization proposition feasible. 12 refs

    Several attractive theoretical ideas suggest the existence of one or more 'hidden sectors' consisting of standard model singlet fields, some of which may not be too heavy. There is a profound reason to think that the Higgs sector might provide the first access to these hidden sectors. This scenario could affect Higgs phenomenology in drastic ways.

La discusión critica cuatro aspectos de dichos estudios: i su método de estratificación, que define grupos sociales por medio de categorías altamente variables en el tiempo; ii su medida de la segregación, que no considera áreas suburbanas ni tampoco soluciona el problema de la escala; iii su conexión con problemas sociales, que presenta ciertos sesgos de reificación del espacio; y iv sus propuestas de política pública, que plantean líneas de acción fundadas en premisas discutibles. Dada la considerable influencia de estos estudios en la discusión de políticas públicas pro mixtura social, consideramos importante establecer nexos con la especificidad de nuestros contextos sociales, históricos y culturales, elaborando una racionalidad crítica que se extienda más allá de un excesivo empirismo.

    Full Text Available The seismic risk doesn’t depend on the threat or the probability of occurring a seismic event, but also the highest vulnerability that many buildings have, because they haven’t been built with the appropiate regulations, also they don’t have minimun structure conditions, shape, strength which make them more susceptible to damage. The purpose of the research is to develop a map that shows the seismic vulnerability of housing one or two floors of residencial Comuneros, Chapinero and Claret neigborhoods in the comuna 7 of Cúcuta city. We used the Vulnerability index method by (Benedetti and Petrini 1984 we chose a propability sample of 336 houses distributed proportionally according to the neighborhood. The instrument applied in this researh is designed according to the parameters that The Colombian Earthquake Resistent Design and Construction NSR- 98 stablished, the investigation showed that 70% of these houses are into the highest vulnerability seismic level, the 22% is into the intermediate vulnerability seismic level and just the 8% of the tested houses are into the lowest vulnerability seismic level, and the research also conclude that exists a big relation between the level of the seismic vulnerability of these houses and the social level of their habitants.

  2. Decomposition analysis of the variations in household electricity consumption in Brazil; Analise de decomposicao das variacoes no consumo de energia eletrica no setor residencial brasileiro

    Achao, Carla da Costa Lopes

    2009-09-15

    Introduced at the end of the 1970s to study the impacts of structural changes on electricity consumption by industry, index decomposition analysis techniques have been extended to various other areas to help in the formulation of energy policies, notably in developed countries. However, few authors have applied these techniques to study the evolution of energy consumption in developing countries. In Brazil, the few available studies have focused only on the industrial sector. In this thesis, we apply the decomposition technique called the logarithmic mean Divisia index (LMDI) to electricity consumption of the Brazilian residential sector, to explain its evolution in terms of the activity, structure and intensity affects, over the period from 1980 to 2007. The results obtained in a preliminary analysis point out, in a general way, that the observed variables in electricity consumption in the Brazilian residential sector are, mainly, the product of the increase in the number of consumers and the changes in the specific consumption of electricity in households. In a further analysis, carried out when the structure is given through consumers participation in consumption categories (Low Income and Conventional) taken from an overall point of view, although the intensity and activity effects may be considered the main explaining factors in consumption variation, the structure effect stands out in the period immediately after the 2001 rationing, as a reflect of the changes in the inclusion criteria in the Low Income category, specifically in the Northeast.

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

The objective of this study is to empirically test...... the relationship between sectoral shares and economic growth by using the panel data for 20 developed countries. The results of the granger causality suggest that both services and agriculture sectors do granger cause economic growth, whereas industrial sector does not granger cause growth.

  6. Regional transport sector mitigation options

    International Nuclear Information System (INIS)

    Zhou, Peter

    1998-01-01

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

    The French Labour Code, which provides full protection against moral and sexual harassment, is not applicable to public sector workers. The public hospital is however not exempt from such behaviour, which could go unpunished. Public sector workers are therefore protected by the French General Civil Service Regulations and the penal code.

    Full Text Available El presente trabajo plantea una propuesta para la “Disposición Higiénica de Excretas” a través de ”sistemas cloacales alternativos”. Muestra la experiencia de Investigación-Acción participativa, realizada en dos comunidades rurales de la provincia de Tucumán, Argentina: Balderrama, Simoca, y Colalao del Valle, Tafí del Valle. Dicha experiencia surge como respuesta a: • una necesidad sentida de estas poblaciones y, • a uno de los objetivos planteados en relación a la Promoción del Saneamiento Ambiental. A través de este modelo “tecnológico constructivo-social”, se intenta resolver no sólo problemas materiales de los sectores más carenciados sino también crear espacios de participación que les permitan incrementar su calidad de vida, “re-elaborando” objetivos y estrategias para un mayor ajuste de las soluciones planteadas frente a la realidad. Es decir, que se apunta al mejoramiento material de las condiciones de vida de las comunidades involucradas, pero a partir del fortalecimiento de su organización y de sus redes de solidaridad, con el propósito de alcanzar un desarrollo sostenido del sector. Todo ello se basó en un proceso en el que grupos, comunidades e instituciones del sector popular, con el aporte de agentes externos, se asociaron para investigar, conocer y comprender sus problemas y para proponer sus propias estrategias de acción, en el entendido que ellos son los verdaderos transformadores de su hábitat. Este “Proyecto Compartido” posibilitó “resignificar” la práctica de Investigación y Extensión, ya que los mecanismos empleados permitieron el “hacer juntos” de comunidad y técnicos, de manera que ¨Investigación y Acción¨ dejaran de ser acciones separadas, evitando el desgaste del poblador rural sometido a objeto de estudio e involucrándolo en el proceso de “toma de decisiones” y de “ejecución”.

Nos vemos provocados a recuperar progresivamente ese conocimiento especialmente cuando el paso de los años identifica a una arquitectura como obra maestra para la arquitectura actual, como ocurre con el grupo residencial Romeo y Julieta. Este artículo pretende contribuir a facilitar su conocimiento compilando información, incidiendo en algunos detalles menores que habitualmente se obvian y aportando nuevas fotografías y dibujos realizados para esta ocasión. Como consecuencia surgen las relaciones desde la experiencia concreta de esta obra con la producción previa y posterior de Hans Scharoun y vuelve a brillar la trayectoria investigadora del arquitecto. SUMMARY The complex circumstances that typically surround the making of a work of architecture, hinder the simultaneous systematization of reflection and the transfer of experience. We are gradually brought to recover that knowledge, especially when the passage of time identifies a building as a masterpiece for current architecture, as has occurred with the ‘Romeo and Julia’ residential group. This article aims to raise awareness of them by gathering information, focusing on small details that are usually ignored and adding new photographs and drawings made for this occasion. As a result, relationships arise from the specific experience of this work with the previous and later production of Hans Scharoun and the research career of the architect shines again.

    Directory of Open Access Journals (Sweden)

    Neuma Aguiar

    Full Text Available RESUMO Neste artigo propomos uma análise do trabalho doméstico não remunerado a partir da conjunção de duas perspectivas: a da estratificação social e a da economia doméstica. Para tal desenvolvemos uma escala de estratificação residencial, construída a partir do emprego da teoria da resposta ao item para a coleção dos bens empregados na produção doméstica em cada domicílio participante da Pesquisa de Usos do Tempo de Belo Horizonte. A utilização dessa escala possibilita, por um lado, a valoração de atividades não remuneradas no âmbito doméstico e da ocupação de “dona de casa”, e por outro, o estudo da divisão sexual do trabalho por estrato social. A solidez da escala é indicada pela correlação extremamente alta entre ela e uma escala idêntica, construída a partir de dados da Pesquisa de Orçamentos Familiares, assim como pela correlação relativamente alta com outros índices de estratificação baseadas na ocupação dos indivíduos. Os principais resultados indicam, de um lado, a persistência da divisão sexual do trabalho em todos os estratos socioeconômicos, e, de outro, uma baixa correlação negativa entre status e tempo de cuidados domésticos, exceto para os homens durante fins de semana, quando a relação se torna positiva.

    Status of the reforms in Lithuania's energy sector and preparation of updated Energy Strategy is presented in this article. The new Strategy has been worked out considering the conclusions of different studies as well as the changes that have taken place in Lithuania and restructuring of its energy sector, the guidelines of the European Union. The principal objectives of the country's energy sector consists in reliable and safe energy supply with minimum expenses, increasing efficiency of energy utilisation, introducing principles of market economy within the sector, reducing environmental impacts, preparing Lithuania's energy sector for integration into the EU. In the field of nuclear energy the top priority is to ensure the safety of Ignalina NPP. Ignalina NPP will only be operated if and as long as it is safe. Two most likely scenarios for the future operation of Ignalina NPP are analysed in the draft Strategy. According to scenario 1, reactor 1 and 2 are to be operated half of the design service life, until 2005 and 2010 respectively, i.e. until the gap between the graphite and fuel channels reaches the critical margin. In accordance with the second scenario, the fuel channels are to be replaced as envisaged in the design, after which the reactors may be operated for another 10 - 15 years

    2013-01-01

    Regulation of the Power Sector is a unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems. The need for generation to occur at the time of use occasioned by the impracticality of large-scale electricity storage coupled with constant and often unpredictable changes in demand make electricity-supply systems large, dynamic and complex and their regulation a daunting task. Conceptually arranged in four parts, this book addresses both traditional regulatory frameworks and also liberalized and re-regulated environments. First, an introduction gives a full characterization of power supply including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation and the third looks at the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute form the content of the fourth part. In a sector where regulatory design is the key driver...

    Natural gas in Canada represents 29% of the primary energy and 42% of the energy used in the industrial sector. The biggest users are the manufacturing industries for which the low cost of natural gas and the quality of products resulting from its use represent a serious advantage in a more and more competitive market. This document takes stock of the situation of natural gas and gas-related technologies in Quebec. The first part recalls the historical evolution of the gas distribution network in Quebec and its present day situation. Then, some technical-economical data about the consumption of natural gas in Quebec are presented according to the sectors of use. The third part treats of the R and D activities linked with the gas sector, in particular the activities of the two main research organizations: the technical centre of natural gas and the research group in gas technologies of the Polytechnique school of Montreal.

La liberación de suelo como oportunidad para una renovación de usos ha transformado el territorio generado mezcla de funciones y actividades, superposición de tejidos y contrastes de densidades entre otros factores. Se han despertado expectativas de carácter económico y urbanístico. Diferentes Planes de Ordenación han condicionado estos procesos, bien mediante el mantenimiento de la actividad fabril o bien impulsando su traslado y cierre para sustituir las edificaciones por construcciones residenciales o de servicios. Para valorar cómo se han regulado dichas transformaciones de usos y cómo se han configurado en el territorio, este trabajo analiza la producción del espacio residencial en los polígonos industriales de Madrid a partir de la normativa del Plan General  de 1997.

    Full Text Available The paper emphasises the role of the market-type mechanisms within the activity of the organisations from the public sector. The end of the 20th century was defined by the effects of the public sector reform. The public sector is placed within the cultural and political environment of each country and the reforms have aimed to redefine the structures of the state organisations in the economy and the relationships such as market-government, government-bureaucracy, government- citizens, bureaucracy-citizens, civil servants-politicians-citizens. The public sector reform, achieved at the managerial systems, organisational structures and regulations levels is accompanied by specific and structural reforms. Accepting the market-type mechanisms instead of bureaucratic mechanisms, meaning not the simple provision of public services but the creation of some governmental “actors”, functioning completely on commercial bases, supporting the development of the partnerships between the public and private sector, introducing privatisation is achieved in view of creating “the facilitating state”. We discuss about “facilities” such as citizens and society involvement in public businesses, making public administration more citizen-friendly and the state closer to the public need. The citizens’ involvement, as customers in the flow of the public service contributes to creating an organic ensemble characterised by two fundamental dimensions: level and type of influence of the customers and the private-public dichotomy. Synthesising, the relationships and market mechanisms enable to the public sector to get closer to the public needs and to create a modern administration based on efficiency, effectiveness and openness towards change.

    The national diarrheal disease control program has made progress against diarrheal illness in Indonesia, but diarrhea still accounts for 130,000 deaths of under-5 year olds annually. The potential of the private sector had been virtually untapped until the PRITECH Project designed and implemented a private sector based program to complement government efforts to reduce childhood morbidity and mortality related to diarrhea. PRITECH wanted to motivate commercial firms to invest the capital necessary to commercialize oral rehydration salts (ORS) so that program self-sufficiency would be maximized over the long term without depending upon donor support. Sections describe the lack of commercial sector ORS promotion, supply and demand factors, raising interest in ORS, conditions for change, the potential market for ORS, demand, production capacity, previous collaborative efforts, areas for improvement, PRITECH's role as catalyst, coordination with commercial companies, marketing workshops, collaboration with the Indonesian Medical Association, the handwashing campaign, and program impact. Although the program has been in place for just 1 year, sales of ORS have increased along with the degree of sustainable collaboration among local institutions. The author stresses that for the model to be successfully replicated elsewhere, the government, medical and pediatric associations, the World Health Organization, UNICEF, groups which can promote oral rehydration therapy, and opinion leaders in the medical community must be involved. Finally, note is made that the image of ORS must be improved and that the work of the public and commercial sectors can be complementary.

  10. Communication in third sector organisations

    Directory of Open Access Journals (Sweden)

    Patricia Durán-Bravo, M.A.

    2010-01-01

    Full Text Available Third sector organisations favour the social development due to their capacity to produce human and social capital in society (Putman, 2001. In order to achieve social welfare third sector organisations need to produce a positive change in the relations among individuals, groups and institutions in a society. The expectations about the third sector organisations’ transparency and capacity to tackle social problems are increasing worldwide. In Mexico, this problematic is more complex because there is a low level of professionalism, transparency, accountability and participation culture in the organized civil society (ITAM, 2010. The development of the organized civil society in Mexico will depend to a great extent on its capacity to communicate its values to society and achieve a cultural and social change. Therefore, the third sector organisations must adopt strategic initiatives to reinforce their credibility and reputation, because the public and private donors are increasingly more demanding in their criteria to grant resources to social projects; and because the Mexican society has a low participation level and faces increasingly more complex social problems.

    Full Text Available SUMMARY As a current observation this contribution intends to situate origins of the notion of the primacy of residential quality in urban creation in a historical context before May ’68 and to show the relevance and actuality of this concept in emerging contemporary projective urban architectural practices. This is done through a retrospective re–reading of a major research contribution of architectural residential sociology elaborated by Henri Raymond and his team of ISU directed by Henri Lefebvre. A summary of results were published in 1966 as l’Habitat pavillonnaire and re–published in 2001 with the three different components together with the never published applied methodological instruction for inquiries of deep interviews with residents in suburban single family urban zones. This groundbreaking qualitative interpretive approach in social sciences with repercussions in residential architectural design orientations is regarded by the author as a still valid example of how social sciences can provide a more profound understanding of residents’ perceptions of their spatio–social residential situation, hábitat y habitar, than what the standard survey can offer for design guidance.RESUMEN Como observación actual, esta contribución pretende situar los orígenes de la idea de la primacía de la calidad residencial de la creación urbana en un contexto histórico antes de mayo del 68 y mostrar la relevancia y la actualidad de este concepto en las prácticas arquitectónicas urbanas contemporáneas emergentes.

    Reflections on science and the communication sector. In this contribution I will reflect about successes and failures in communicating climate change and air pollution sciences to the general public. These communication efforts included writing popular articles, giving public presentations, working with people from the social scientists and artists. Giving the fact that communication is a very important (economic) sector on its own, the question is to what extent scientists should enter that sector, whether scientists are at all accepted in that sector, whether they should use the expertise in that sector, or whether they should merely provide the knowledge to be used by that sector.

    Accepting the market-type mechanisms instead of bureaucratic mechanisms, meaning not the simple provision of public services but the creation of some governmental “actors”, functioning completely on commercial bases, supporting the development of the partnerships between the public and private sector, introducing privatisation is achieved in view of creating “the facilitating state”. We discuss about “facilities” such as citizens and society involvement in public businesses, making public administration more citizen-friendly and the state closer to the public need. The citizens’ involvement, as customers in the flow of the public service contributes to creating an organic ensemble characterised by two fundamental dimensions: level and type of influence of the customers and the private-public dichotomy. Synthesising, the relationships and market mechanisms enable to the public sector to get closer to the public needs and to create a modern administration based on efficiency, effectiveness and openness towards change.

    As in the software industry where computer aided software engineering (CASE) methodologies and tools are commonly used, CERN endeavours to introduce this technology to improve the efficiency of designing, producing and maintaining software. A large project is currently under development in the administrative area whereas a dedicated group had been set up to evaluate state of the art techniques for software development relating to physics experiments. A similar activity, though on a smaller scale, has been initiated in the accelerator sector also in view of the large amount of software that will be required by the LEP200 and the LHC projects. This paper briefly describes this technology and gives an account of current experience with the use of CASE methods and tools for technical projects in the accelerator sector at CERN. (author)

    The electricity industry is expanding, with new supply and infrastructure development equivalent to 35 per cent of existing capacity over the next 20 years. This paper examines the preliminary results of a human resources sector review providing industry specific labor force data. The key objectives of the review were to develop detailed industry profiles, identify root causes of human resources issues, identify industry best practices and develop a human resources strategy for the Canadian electricity sector. Estimates of current employment were provided, with age of employees, retirement projections, regional projections and estimated supply/demand gaps. Current shortages were identified, including wind energy technicians. The paper also identified a declining Canadian born labor force and a concurrent dependence on immigrants. A project research methodology was provided with a list of participating major employers. tabs., figs.

    Full Text Available Residential mobility is an increasing phenomenon among the population, but in particular among the old people. The retirement is usually a moment in which more and more people decide to change their place of residence. This is a decision which mainly responds to social, economic and cultural factors; nevertheless, it is also necessary for the study of the mobility to deepen in other geographic, environmental, familiar, social and cultural reasons. In this article, reasons that have impelled to old residents living in Madrid to change the place of residence (both in a definitive or temporary way are analyzed; for this, qualitative methodology has been used. It is necessary to know well those reasons, not only to plan places for retirement in the future, also to plan services and equipment that such displacements require, and for the contribution to the improvement of the quality of life of these people.

  4. Dissipative hidden sector dark matter

    Science.gov (United States)

    Foot, R.; Vagnozzi, S.

    2015-01-01

    A simple way of explaining dark matter without modifying known Standard Model physics is to require the existence of a hidden (dark) sector, which interacts with the visible one predominantly via gravity. We consider a hidden sector containing two stable particles charged under an unbroken U (1 )' gauge symmetry, hence featuring dissipative interactions. The massless gauge field associated with this symmetry, the dark photon, can interact via kinetic mixing with the ordinary photon. In fact, such an interaction of strength ε ˜10-9 appears to be necessary in order to explain galactic structure. We calculate the effect of this new physics on big bang nucleosynthesis and its contribution to the relativistic energy density at hydrogen recombination. We then examine the process of dark recombination, during which neutral dark states are formed, which is important for large-scale structure formation. Galactic structure is considered next, focusing on spiral and irregular galaxies. For these galaxies we modeled the dark matter halo (at the current epoch) as a dissipative plasma of dark matter particles, where the energy lost due to dissipation is compensated by the energy produced from ordinary supernovae (the core-collapse energy is transferred to the hidden sector via kinetic mixing induced processes in the supernova core). We find that such a dynamical halo model can reproduce several observed features of disk galaxies, including the cored density profile and the Tully-Fisher relation. We also discuss how elliptical and dwarf spheroidal galaxies could fit into this picture. Finally, these analyses are combined to set bounds on the parameter space of our model, which can serve as a guideline for future experimental searches.

    private sector . After all, corruption does not just involve government. Business people and lawyers and citizens pay the bribes, even as they condemn bribery. They should be invited to become part of the solution. But how? The first point to note is that business people and citizens know where corruption exists and how corrupt systems work. Citizens understand how bribery shapes the services they receive or don’t receive. Accountants know the illicit games played with audits and taxes. Lawyers understand corrupt legal practices. Business people know all about corrupt

  10. Energy conservation in agriculture sector

    1991-01-01

    The annual production of foodgrains in India rose from 50.8 million tonnes in 1950-51 to 178 million tonnes in 1989-90. One of the factors which led to this impressive growth is the continued increase in input of mechanization and energy in the agricultural sector by way of tractors running on diesel and pumps (for water supply) based on diesel and electricity. Electricity consumption in agricultural sector rose from 833 million kWh in 1960-61 to 47000 million kWh in 1990-91 and is further expected to rise to 81.8 TWH in 1999-2000. Considering the heavy investments required for production and supply of energy, it has become imperative to avoid wasteful use of energy and to use energy more efficiently. This can be done by : (1) Changing the electricity tariff structure from the present horse power related rates to energy consumption related rates. This will induce farmers to avoid waste in energy use. (2) Adopting energy efficiency measures. These measures are : (1) replacement of inefficient foot valves, suction pipes and delivery pipes of the pump sets, (2) increasing power factor of electric motors used for pumps sets, (3) reducing distribution losses over LT lines, and (4) optimizing use of fertilizers. This optimization will indirectly conserve energy by reducing electricity consumption by fertilizer industry. (M.G.B.). 5 refs., 4 tabs

    We probe a slice of the massive winding sector of bosonic string theory from toroidal compactifications of Double Field Theory (DFT). This string subsector corresponds to states containing one left and one right moving oscillators. We perform a generalized Kaluza Klein compactification of DFT on generic 2n-dimensional toroidal constant backgrounds and show that, up to third order in fluctuations, the theory coincides with the corresponding effective theory of the bosonic string compactified on n-dimensional toroidal constant backgrounds, obtained from three-point amplitudes. The comparison between both theories is facilitated by noticing that generalized diffeomorphisms in DFT allow to fix generalized harmonic gauge conditions that help in identifying the physical degrees of freedom. These conditions manifest as conformal anomaly cancellation requirements on the string theory side. The explicit expression for the gauge invariant effective action containing the physical massless sector (gravity+antisymmetric+gauge+ scalar fields) coupled to towers of generalized Kaluza Klein massive states (corresponding to compact momentum and winding modes) is found. The action acquires a very compact form when written in terms of fields carrying O(n,n) indices, and is explicitly T-duality invariant. The global algebra associated to the generalized Kaluza Klein compactification is discussed.

    2007-07-01

    India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

    The paper deals with the problems related to the private participation in the infrastructure projects developed mainly in the transient economies. The comparatively larger risk volatility of this economies is counterbalanced by the expected high return rates of these projects. In these circumstances the paper presents the possibility to use the World Bank Group support for enhancing the private sector investments. After a description of the type of support able to be given, some examples are presented related to an energy project in Pakistan and to two others in China. There is also given a synthesis concerning the potential places in Romania were such projects may be achievable. (author). 1 fig., 3 tabs., 2 refs

    Purpose The purpose of this paper is to expand attention to responsible leader behavior in the world's health sectors by explaining how this concept applies to health sectors, considering why health sector leaders should behave responsibly, reviewing how they can do so, and asserting potential impact through an applied example. Design/methodology/approach This paper is a viewpoint, reflecting conceptualizations rooted in leadership literature which are then specifically applied to health sectors. A definition of responsible leader behavior is affirmed and applied specifically in health sectors. Conceptualizations and viewpoints about practice of responsible leader behavior in health sectors and potential consequences are then discussed and asserted. Findings Leadership failures and debacles found in health, but more so in other sectors, have led leadership researchers to offer insights, many of them empirical, into the challenges of leadership especially by more clearly delineating responsible leader behavior. Practical implications Much of what has been learned in the research about responsible leader behavior offers pathways for health sector leaders to more fully practice responsible leadership. Social implications This paper asserts and provides a supporting example that greater levels of responsible leader behavior in health sectors hold potentially important societal benefits. Originality/value This paper is the first to apply emerging conceptualizations and early empirical findings about responsible leader behavior specifically to leaders in health sectors.

  15. AGENCY PROBLEMS IN PUBLIC SECTOR

    2012-07-01

    Full Text Available Agency theory analyses the effects of contractual behaviour between two parties: principal(s and agent(s. This relation is inevitably characterized by information asymmetry because agent holds a substantially larger volume of information than the principal. Due the negative effects of information asymmetry for the principal, this should cover supplementary costs with monitoring agents and/or grant incentives. The first objective of this paper is to emphasize the effects of information asymmetry, particularly on adverse selection and moral hazard. The second objective is to evaluate the negative effects of information asymmetry and to assess the viability of solutions proposed by scholars for mitigation. The third objective is linked with personal contribution, respectively to highlight specificity of agency theory in public sector and the mechanisms of action in this particular field. In this paper, literature is mainly based on scholars’ contribution to the proposed theme. Little literature approaches agency theory in public sector, in most cases the analysis being restricted to general issues. Research methodology is based on synthesizing relevant information from literature and adapting them to public sector particularities. The results reflect some threats for public bodies in their contracting activity. Conclusions present also a set of solutions which could be used by public institutions to optimize their activity of mitigating information asymmetry’s effects. These solution guidelines could represent a useful instrument for make more efficient public money spending. Personal contribution and the novelty of this paper consist in presenting a new approach regarding mechanisms of managing information by agents. In case of public institutions, principals have more opportunities the take possession over the information managed by the agent. Nevertheless, agents can limit the principal’s access

    Iliadou, Ekaterini N.

    2009-01-01

    This paper provides an outlook of the electricity market reform in Greece which started in 2001 and is still developing slowly. This is related to the persisting dominance of the incumbent company and the specificities of the electricity sector of Greece which is heavily dependent on indigenous lignite firing generation, while being located in the periphery of the EU internal electricity and gas markets. Competition through enhancing electricity trade in the region is limited to date, as the establishment of an internal market in South East Europe also progresses slowly. Development of competition through gas-firing generation by new entrants has been the priority adopted by State and Regulator's policies. However, the gas supply market in Greece and in the region still lags behind. (author)

    2014-07-01

    Full Text Available Globalization, deregulation and technological improvements have resulted in increase in M&A across the globe. There is enormous literature existing in the advanced economies. However, very little information is available regarding M&A in India. Various sectors have witnessed differential involvement in M&A activity indicating higher participation by some. Particularly, certain sectors such as financial services and pharmaceuticals demonstrate higher M&A activity. To emphasise differential importance of sectors in M&A activity, it is necessary to conduct a sector-wise analysis. Accordingly, this study attempts to investigate the differential representation of various sectors in M&A. Further, it explores the role played by India in the rising global M&A activity. In light of this, it specifies the factors driving consolidation in the financial sector globally.

  20. Private Sector Credit and Inflation Volatility

    Directory of Open Access Journals (Sweden)

    Lorna Katusiime

    2018-04-01

    Full Text Available This paper investigates the effect of inflation volatility on private sector credit growth. The results indicate that private sector credit growth is positively linked to the one period lagged inflation volatility. Given that past monetary policy actions continue to affect the targeted variables due to the substantial lags in the transmission mechanism, the positive response of private sector credit growth to past inflation volatility suggests a credible monetary policy regime in Uganda, which has led to a reduction in the level of macroeconomic uncertainty and the restoration of favorable economic conditions and prospects, thus increasing the demand for credit. Further, the study finds that the lagged private sector credit growth, nominal exchange rate, and inflation have a statistically significant effect on private sector credit growth while financial innovation, interest rates, and GDP growth appear not to be important determinants of private sector credit growth. The robustness of our findings is confirmed by sensitivity checks.

  1. Financial Sector Structure and Economic Growth

    Economists consider a well-functioning financial sector to be of first order importance for a modern (capitalist) economy. However, in the aftermath of the financial crisis a debate about the future role of the financial sector emerged and many commentators have called into question whether...... the financial sector actually creates value for the wider society. This research, which is part of a broad research project “Nordic Finance and the Good Society”, aims to contribute to this debate by studying the role of the financial sector structure for economic development of an economy. Therefore......, it proceeds in five steps. First, it provides some reflections on the financial sector and the existing literature studying financial sector structure and its association with economic development.

  2. Third sector primary care for vulnerable populations.

    Crampton, P; Dowell, A; Woodward, A

    2001-12-01

    This paper aims to describe and explain the development of third sector primary care organisations in New Zealand. The third sector is the non-government, non-profit sector. International literature suggests that this sector fulfils an important role in democratic societies with market-based economies, providing services otherwise neglected by the government and private for-profit sectors. Third sector organisations provided a range of social services throughout New Zealand's colonial history. However, it was not until the 1980s that third sector organisations providing comprehensive primary medical and related services started having a significant presence in New Zealand. In 1994 a range of union health centres, tribally based Mäori health providers, and community-based primary care providers established a formal network -- Health Care Aotearoa. While not representing all third sector primary care providers in New Zealand, Health Care Aotearoa was the best-developed example of a grouping of third sector primary care organisations. Member organisations served populations that were largely non-European and lived in deprived areas, and tended to adopt population approaches to funding and provision of services. The development of Health Care Aotearoa has been consistent with international experience of third sector involvement -- there were perceived "failures" in government policies for funding primary care and private sector responses to these policies, resulting in lack of universal funding and provision of primary care and continuing patient co-payments. The principal policy implication concerns the role of the third sector in providing primary care services for vulnerable populations as a partial alternative to universal funding and provision of primary care. Such an alternative may be convenient for proponents of reduced state involvement in funding and provision of health care, but may not be desirable from the point of view of equity and social cohesion

  7. Industrial Disputes in the Construction Sector

    Directory of Open Access Journals (Sweden)

    L.J Perry

    2012-11-01

    Full Text Available The Cole Royal Commission enquiry into the building and construction (abbreviated to ‘construction’ sector recommended controversial workplace-relation reforms for that sector. The recommended changes are likely to be enshrined in legislation within the year. The Commission drew on analyses of industrial disputes that focused, in the main, on quite recent experience. This paper attempts to give a broader historical perspective on disputes in that sector by considering the pattern of disputes for the entire post-World War II period. Accordingly, data on disputes and employees during the entire period are gathered from Australian Bureau of Statistics current and archived sources. These data are classified according to sector (construction versus non-construction and analysed. It is found that the strike rate has, on average, been greater in the construction sector than in the non-construction sector. However, there have been periods during which disputes in the construction sector have been relatively low. The most recent period was during the period of the Accord (1983-96, during which the strike rate in the construction sector fell relatively strongly. The analysis of this relatively broad historical period draws attention, among other things, to the possibility that the sort of strategies employed during the Accord years – strategies of cooperation and consensus building – may provide a more effective means of bringing industrial peace to the workplace relations scene of the construction sector than policies that are relatively confrontational.

    Antoci, Angelo; Galeotti, Marcello; Iannucci, Gianluca; Russu, Paolo

    2015-01-01

    This paper studies the dynamics of a two-sector economy (with a natural resource-dependent sector and an industrial sector) characterized by free inter-sectoral labor mobility and heterogeneity of agents (workers and entrepreneurs). In such a context, we analyze the effects of the deterioration of natural resources, caused by the production activity of both sectors, on inter-sectoral movements of the labor force (structural changes), on ecological dynamics and on the revenues of workers and entrepreneurs. As in the seminal work by Matsuyama (1992), we obtain that a low productivity of labor in the resource-dependent sector can fuel the industrialization process. However, differently from Matsuyama, in our model the industrialization process may give rise to a reduction in workers’ revenues if the contribution to environmental depletion of the industrial sector, per unit of product, is higher than that of the resource-dependent one.

    Directory of Open Access Journals (Sweden)

    Capraru Bogdan

    2011-07-01

    Full Text Available Recent turmoil in the global financial system has impacted severely on the banking sector with many banks suffering large losses and necessitating the need to raise additional capital privately or through their respective national governments. In our study we investigate the impact of structural reforms performed throughout the European Union (EU accession process on competition and contestability of banking systems in Romania. The literature of the measurement of competition can be divided into two major approaches: structural and non-structural. The structural approach to the assessment of competition embraces the Structure-Conduct-Performance Hypothesis (SCP and the Efficient Structure Hypothesis (ESH. The structural approach, as the name suggests, assesses bank competition by examining measures of market structure such as concentration ratios (the share of assets held by the top 3 or 5 institutions or indices (e.g., the Herfindhal-Hirschman index and supposes that higher concentration in the banking market causes less competitive bank conduct and leads to higher bank profitability. The SCP model is originally developed by Bain (1956. The second approach, ESH, developed by Demsetz (1973 and Peltzmann (1977 suggests that the superior performance of the market leaders determines the market structure, implying that higher efficiency produces both higher concentration and greater profitability. The non-structural indicators of competition are mainly based on the measures of monopoly power developed by Lerner (1934. The Lerner Index suggests the mark-up of price over marginal cost. An alternative non-structural indicator of the degree of market competition is the Panzar and Rosse (1987 H-statistic. The H-statistic measures the extent to which changes in banking costs are reflected in changes in banking revenues. In order to examine the level of competition and market power of banks in Romania for period 2003 - 2009, we estimate the non

    Directory of Open Access Journals (Sweden)

    Aliyu Mamman, Ph.D

    2013-07-01

    Full Text Available The real sector is a strategic component of an economy because it produces and distributes tangible goods and services required to satisfy aggregate demand in the economy. For this reason, there is the need for adequate credit flow from the banking industry to the real sector, which in the Nigerian case, the credit flow has been grossly inadequate. This study is carried out to examine the impact of credit to private sector (CPS on the real sector of Nigeria with a view to assess the significant contribution of CPS to real sector growth in Nigeria. The study used aggregate time series data from 1986 to 2010, which was drawn from central bank of Nigeria (CBN statistical bulletin and CBN annual report and statement of accounts. The data was analysed using multiple regression and based on the coefficient of determination (R square, the study reveals a 96.1% variation between the CPS and real sector growth in Nigeria. The study cocludes that there is a statistically significant impact of credit to private sector on the real sector of Nigeria. This, suggest that the performance of the real sector is greatly influence by credit to private sector. The study recommends that the federal government of Nigeria through the central bank of Nigeria (CBN should enhance the financing of the real sector as well as improve credit flow to the sector because of its strategic importance in creating and generating growth of the economy.

    Sector 7-8 is the first sector of the LHC to become fully operational. All the magnets, cryogenic line, vacuum chambers and services are interconnected. The cool down of this sector can soon commence. LHC project leader Lyn Evans, the teams from CERN's AT/MCS, AT/VAC and AT/MEL groups, and the members of the IEG consortium celebrate the completion of the first LHC sector. The 10th of November was a red letter day for the LHC accelerator teams, marking the completion of the first sector of the machine. The magnets of sector 7-8, together with the cryogenic line, the vacuum chambers and the distribution feedboxes (DFBs) are now all completely interconnected. Sector 7-8 has thus been closed and is the first LHC sector to become operational. The interconnection work required several thousand electrical, cryogenic and insulating connections to be made on the 210 interfaces between the magnets in the arc, the 30 interfaces between the special magnets and the interfaces with the cryogenic line.

    This paper examines whether sectoral backward and forward linkages can generate positive externalises in sectoral innovation through diffusion of technological knowledge, both across countries within a sector or across sectors within a country. Using a sample of 14 OECD countries and 12 sectors over the period 1995-2005 we find that forward linkages enhance sectoral innovation. Intra sectoral slipovers are important among sectors and countries with low-to-medium R an D intensity while inter sectoral slipovers have a major impact on sectors with high R and D intensity.

  14. Interaction in the dark sector

    del Campo, Sergio; Herrera, Ramón; Pavón, Diego

    2015-06-01

    It may well happen that the two main components of the dark sector of the Universe, dark matter and dark energy, do not evolve separately but interact nongravitationally with one another. However, given our current lack of knowledge of the microscopic nature of these two components, there is no clear theoretical path to determine their interaction. Yet, over the years, phenomenological interaction terms have been proposed on mathematical simplicity and heuristic arguments. In this paper, based on the likely evolution of the ratio between the energy densities of these dark components, we lay down reasonable criteria to obtain phenomenological, useful, expressions of the said term independent of any gravity theory. We illustrate this with different proposals which seem compatible with the known evolution of the Universe at the background level. Likewise, we show that two possible degeneracies with noninteracting models are only apparent as they can be readily broken at the background level. Further, we analyze some interaction terms that appear in the literature.

  15. The energy sector in Argentina

    International Nuclear Information System (INIS)

    2016-01-01

    This article first outlines that Argentina produces an important part of its hydrocarbon consumption and comment various aspects of this production: hydrocarbons are at the heart of the Argentinian energetic model; conventional hydrocarbon reserves are however decreasing; the public operator remains the main actor even though the market is opened to multinational companies. The article then describes the crisis faced by this energetic model: the energy balance is now a burden; the increasing unbalance between production and consumption can be explained by supply-related as well as demand-related factors; authorities must intervene on hydrocarbon prices and subsidize the oil price on the domestic market. It appears that the future for hydrocarbons in Argentina relies on non-conventional hydrocarbons. Bio-fuels, a key sector of the Argentinian economy, are a matter of trade dispute with the EU and the USA. Apart from hydroelectricity (some new projects are planned), renewable energies are very few developed in Argentina. Appendices propose a graph of the distribution of energy consumption among the different sources, a map indicating locations of the main exploited hydrocarbon deposits, a presentation of mechanisms implemented to subsidize hydrocarbon production

  16. The separated-sector cyclotron

    International Nuclear Information System (INIS)

    1988-01-01

    The injection system of the SSC, consisting of two bending magnets (BM1 and BM2) and a magnetic inflection channel (MIC) in the pole tip of one sector magnet, has been operating without failure since installation. Beam injection efficiency of 100% is achieved with ease. The extraction system performs well. The first extraction element, the electrostatic extraction channel (EEC), located in the second half of the injection valley vacuum chamber, lost a few of its foils of the septum, presumably from interception of a beam of high intensity. This does not interfere with the proper functioning of the channel. The 5 Mω damping resistor located between high-voltage power supply and the EEC had to be repaired twice during the past year. A slight modification to the design should prevent recurrence of this problem. Although the second extraction element, i.e. the first septum magnet SPM1, has been functioning satisfactorily, its driving mechanism had to be repaired during a scheduled shut-down. The final extraction element, i.e. the second septum magnet SPM2 is functioning well, but a water leak on the inner liner (collimator) made it necessary to remove SPM2 for repairs. A slightly modified driving system has been fitted to this magnet as the previous system occasionally failed to function properly due to unexpectedly high forces

  17. Optimization in the energy sector

    International Nuclear Information System (INIS)

    2015-01-01

    The implementation of the energy transition and the developments in the national and international Energy markets constantly require sound analysis and new answers. The symposium ''optimization in the energy sector'' gives an overview of methods and models that can be practically used for decision support. Storage and electromobility as demand flexibility are important factors for the long-term design of the German and European energy system. But methodological aspects such as the consideration of uncertainties at the conference an important place is given. A key issue is also the short and medium term further development of the electricity market design. Not only broadly but also in detail e.g. the standard benefit and intraday markets there is considerable potential for optimization, which will be discussed in the context of technical presentations. And in view of challenging market environment is also new approaches to portfolio management a great importance for the practice. Therefore we are convinced that the Conference and its results for energy companies, public services and new entrants in the energy industry as well are of interest as for consultants, authorities, associations and energy economic research institutes.

Venezuela has oil reserves of 73 billion barrels, gas reserves of 143 TCF and coal reserves of 6 billion BOE. The country has a refining capacity of 2.9 million barrels per day, a petrochemical capacity of 7.7 million tons per year, and a coal capacity of 4.6 million tons per year. The largest refiners in Venezuela are Shell, Exxon, PDVSA, Mobil, BP, Chevron and Texaco. In 1996 the total oil and derivatives exports for Venezuela were 2.8 million barrels per day. Fifty-eight companies from 14 countries participate in the Venezuelan upstream market. Fifteen operating agreements have been awarded to 27 companies from nine countries. Third round operating agreements have been awarded to 26 companies and profit sharing agreements are in force involving 14 companies. Four vertically integrated projects (Maraven-Conoco, Maraven-Total, Corpoven-Arco-Texaco-Phillips, and Lagoven-Mobil-Veba) are currently underway. The Orimulsion(R) project, the refining system, the natural gas production, marketing and transmission system, associated future projects for the 1997-2006 time frame, and developments in the field of petrochemicals also have been reviewed. 21 figs

    The Asn is loaded with the control of the nuclear safety and the radiation protection in France: it provides this control, in the name of the state, to protect the workers, the patients, the public and the environment of the risks in relation with nuclear activities. The control is the core business of Asn. Asn so checks the nuclear basic installations (I.N.B.), since their conception until their dismantling, the pressure equipment specially conceived for these installations, the management of the radioactive waste as well as the transport of radioactive substances. Asn also checks all the industrial and research installations as well as the hospitals where are used ionizing radiations. It is a more recent profession there, because dating the reform of the control of the nuclear power of 2002, which constitutes that of the radiation protection. The first responsibility of the activities at risks falls to the one who begins them. This principle applies to all the sectors checked by Asn: an industrialist is responsible for the safety of the nuclear installations which he exploits, a doctor is responsible for the use of the ionizing radiations which he uses.

    Full Text Available Concentration is a situation in which market structure of a sector is controlled by a few firms. At the present time, many analyzing methods such as Herfindahl-Hirschman and N-Firm Concentration Indexes are used to determine market structure.According to market concentration indexes, higher concentration level means more monopolistic market structure, lower concentration level means more full competitive market structure. In this study concentration levels of media groups in Turkish journalism sector within the scope of traditional journalism and internet journalism was analyzed via N-Firm Concentration and H-H Indexes. As a result of the study, it’s seen that first four biggest media groups have monopolistic competition in internet journalism sector,and oligopol structure in traditional journalism sector. According to H-H index analyze, there is monopolistic competition in the sector.

  1. Regulatory reform in Mexico's natural gas sector

    International Nuclear Information System (INIS)

    1996-01-01

    In recent years Mexico has implemented remarkable structural changes in its economy. However, until recently its large and key energy sector was largely unreformed. This is now changing. In 1995 the Mexican Government introduced legislative changes permitting private sector involvement in natural gas storage, transportation and distribution. Subsequent directives set up a detailed regulatory framework. These developments offer considerable promise, not only for natural gas sector development but also for growth in the closely linked electricity sector. This study analyses the changes which have taken place and the rationale for the regulatory framework which has been established. The study also contains recommendations to assist the Government of Mexico in effectively implementing its natural gas sector reforms and in maximizing the benefits to be realised through the new regulatory framework.

    Pineau, Pierre-Olivier

    2008-01-01

    Regional and global integration initiatives push for more electricity sector integration everywhere in the world, including West Africa. The creation of the West African Power Pool (WAPP) in 2000 and important investments under this new structure in 2006 are concrete actions that will result in a more integrated West African electricity sector. But will this integrated sector be more functional than the previous ones? Will the identified electricity sector problems be solved with the new power pool? This paper analyzes how power sector integration is presented by international institutions (the UN Economic Commission for Africa, World Energy Council and World Bank) and identifies three problematic issues with the current integration approach: lack of African ownership, unclear and conflicting reform objectives and uncertainty of integration outcomes

The objective is to develop economical instruments which will help industrialists in adopting less polluting technologies while minimizing concurrence distortions induced by the carbon constraint. For each sector, the report proposes an assessment of emissions, growth prospects, and exposure to international concurrence. It assess to which extent a sector-based objective would be justified and relevant

    Mexico is one of the countries with the highest industrial growth in Latin America. This is due to its geographical location, its vast oil and gas reserves, its membership in NAFTA (North American Free Trade Agreement), and mainly because of its modern economic policies. Mexico is a country in which many opportunities for private investment in the energy sector exist. This paper discussed Bufete Industrial Construcciones' involvement and experiences in the fields of petroleum, electricity and natural gas. The goals to be achieved in the various areas of the energy sector for the 2000-2006 period were summarized for the electric sector, the natural gas sector and the oil and gas extraction sector. The 4 mega projects currently underway include the Cantarell, the Burgos, the Ku-Maloob Zaap and the Delta del Grijalva projects

    As the world’s top energy consumer, China is facing a great challenge to solve its energy supply issue. In this paper energy use from all industrial sectors in China’s economy of 2007 was explored by conducting an extended environmental input–output analysis. We compare the energy consumption embodied in the final demand for goods and services from 29 sectors with the energy demand required for the actual production process in each sector. Two different viewpoints for sectoral energy use have been presented: energy use is directly allocated to the producer entity, and energy use is reallocated to sector’s supply chain from consumption perspective. Our results show that considerable amount of energy use is embodied in the supply chain, especially for “Construction” and “Other Service Activities” sectors, which is not detected if energy use is allocated on a production basis. When further dividing embodied energy consumption into direct energy consumption and indirect energy consumption, total indirect energy consumption is much higher than that of total direct energy consumption, accounting for 80.6% of total embodied energy consumption in 2007. Our results provide a more holistic picture on sectoral energy consumption and therefore can help decision-makers make more appropriate policies. - Highlights: ► A hybrid IO-LCA model was employed to analyze China’s energy use at sectoral level. ► A case study on China’s sectoral energy consumption is done. ► Construction and service sectors are actually energy intensive from the supply chain perspectives. ► Upstream and downstream ectoral collaboration along the whole supply chain is necessary. ► Energy conservation policies should be based upon a comprehensive analysis on sectoral energy use.

    The work objective is to conduct a greenhouse gas emission inventory of the industrial processes in Lebanon for the year 1994. The Lebanese industry has emitted 1924.063 Gg (1.924.063 tons) of Carbon dioxide CO 2 ; 0.0003 Gg (0.3 tons) of carbon monoxide CO; 0.01112 Gg of nitrogen oxide NO; 273.888 tons of non-methane volatile organic compounds and 3.382 Gg (3.382 tons) of sulphur dioxide SO 2 . The cement industry is the major source of CO 2 emissions among the industrial processes in Lebanon. The cement industry is responsible for 76.1% of the total emissions followed by the iron and steel industry which produces 21.68% of the total CO 2 emissions from industrial processes. The NMVOC emissions are mainly produced by the use of asphalt for road paving (98.5% of total emissions by industry) followed by the food and beverage industry (1.2%). The emissions of sulphur dioxide SO 2 come from three industrial sources: the first come from the production of sulphuric acid (69.9% of total industrial emissions), the second from the cement industry (26.4% of total industrial emissions) and the third from the iron and steel mills (3.7% of total industrial emissions). Figures are presented to show the percentage distribution of various industrial sources contributions to CO 2 , NMVOC and SO 2 emissions in Lebanon. Carbon monoxide CO emissions in the industrial sector are very small. The major source is iron and steel mills and the minor source is asphalt-roofing production

    Full Text Available Abstract By reviewing economic performance, two main phenomena could be identified: The first phenomenon is prior to the third wave of the Industrial Revolution in which limited resources are the predominant input; in other words, physical and natural resources are much more credited than human resources. The second phenomenon resonates with the third wave of industrial revolution to the present time, suggesting the pivotal role of humans in production and accumulation of wealth, in which limited resources are no longer considered as predominant input. The present research seeks to understand the behavioral logic of the players of Iran's pharmaceutical sector so as to infer the innovative treatment of the firms in this sector. The concept of innovative system is indebted to the efforts economists and other scientists have made by analyzing economic development based upon technological development. Meanwhile, sectoral innovation system (SIS is a tool for analyzing a technological sector in the context of evolutionary economics with an emphasis on institutional capabilities. The structure of such an approach is composed of some components through which performance analysis of certain technological sector could be made possible. In research, we use expert panel with 12 experts from Universities, Companies, Governmental institutes. The current study wishes to explain structural model of institutional elements in this technological sector. Subsequently, in light of such an explanation, structural elements of this sector would be analyzed through identification of legal and regulatory framework, innovative culture, innovative infrastructure, financial resources, information resources, technology transfer mechanisms, commercialization support and marketing.

    The study of CP violation in the baryon sector is still a relatively new field and offers the possibility to make many CP measurements which could complement those performed in the meson sector. This is especially true of late given the large number of baryons currently being produced at the LHC. Such measurements could help further over-constrain the CKM unitary triangle, as well as furthering our understand of baryongenesis. These proceedings will give an overview of the current state of the search for CP violation in the baryon sector.

There is no effect immediately before a senator's pension scheme improves, and senators, who retire from...... working life after Congress or are elected to a safe seat, are unaffected by private sector career prospects. This indicates that senators react to opportunity costs associated with being in office. Finally, while the results suggest that certain ideological types are more attracted by private sector...

    2011-04-15

    Today, transport accounts for a quarter of Sweden's energy consumption which consists almost exclusively of fossil fuels. But with the increasing demands for reduced emissions of greenhouse gases, the sector's conversion to other fuels or energy sources will have a major impact the next years. This situation is expected to expand the requirements for statistics of energy consumption of the transport sector. The publication is divided into two parts. Chapter 2 describes the official energy statistics for the transport sector and Chapter 3 presents a breakdown of energy use in passenger and freight services for the respective modes.

    2017-05-01

    Full Text Available Testable Higgs partners may be sought within the extensions of the SM Higgs sector aimed at generating neutrino masses at the loop level. We study a viability of extended Higgs sectors for two selected models of radiative neutrino masses: a one-loop mass model, providing the Higgs partner within a real triplet scalar representation, and a three-loop mass model, providing it within its two-Higgs-doublet sector. The Higgs sector in the one-loop model may remain stable and perturbative up to the Planck scale, whereas the three-loop model calls for a UV completion around 106 GeV. Additional vector-like lepton and exotic scalar fields, which are required to close one- and three-loop neutrino-mass diagrams, play a decisive role for the testability of the respective models. We constrain the parameter space of these models using LHC bounds on diboson resonances.

    Strategic concepts and practices first evolved in the private sector, so they evoked much controversy when they migrated to the public sector from the late 1970s onwards. Partly this was about their (in)applicability to the distinctive features of government organizations, in particular their focus...... on public as well as private value, their situation in a political rather than a market environment, their almost exclusive capacity to use legal authority to achieve purposes, and the extent to which they often need to share power over personnel and resources with other public sector agencies.......

  1. Performance measurement in transport sector analysis

    Directory of Open Access Journals (Sweden)

    M. Išoraitė

    2004-06-01

    Full Text Available The article analyses the following issues: 1. Performance measurement in literature. The performance measurement has an important role to play in the efficient and effective management of organizations. Kaplan and Johnson highlighted the failure of the financial measures to reflect changes in the competitive circumstances and strategies of modern organizations. Many authors have focused attention on how organizations can design more appropriate measurement systems. Based on literature, consultancy experience and action research, numerous processes have been developed that organizations can follow in order to design and implement systems. Many frameworks have been proposed that support these processes. The objective of such frameworks is to help organizations define a set of measures that reflect their objectives and assess their performance appropriately. 2. Transport sector performance and its impacts measuring. The purpose of transport measurement is to identify opportunities enhancing transport performance. Successful transport sector management requires a system to analyze its efficiency and effectiveness as well as plan interventions if transport sector performance needs improvement. Transport impacts must be measurable and monitorable so that the person responsible for the project intervention can decide when and how to influence them. Performance indicators provide a means to measure and monitor impacts. These indicators essentially reflect quantitative and qualitative aspects of impacts at given time and places. 3. Transport sector output and input. Transport sector inputs are the resources required to deliver transport sector outputs. Transport sector inputs are typically: human resources, particularly skilled resources (including specialists consulting inputs; technology processes such as equipment and work; and finance, both public and private. 4.

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The subject of this paper is to measure the efficiency of the Macedonian banking sector by applying two approaches: firstly, comparative analysis on the efficiency indicators of the banking sector in the Republic of Macedonia and the countries of Central and Southeastern Europe (CSEE and secondly, Data Envelopment Analysis (DEA. The aim is to provide directions and guidelines for further strengthening of the Macedonian banking sector. According to the comparative analysis of the efficiency indicators (net interest margin and operating costs of the Macedonian banking sector and the countries of CSEE, the countries whose banking sector shows lower operating costs are characterized with a higher level of financial deepening and greater degree of financial intermediation. The high interest margins direct towards unsuitable allocation of financial resources and insufficient competitiveness in the domestic banking sector. When applying the DEA approach, it can be stated that the group of large banks marks the highest efficiency within the Macedonian banking sector. The high concentration degree of banking activities within the group of large banks with a leading role in determining the interest rates, results in a rigid interest policy of the banks. In the direction of strengthening the efficiency of the Macedonian banking sector as a whole, the obtained results show that it is necessary for the banks to be further consolidated so as to utilize the advantages of the economies of scale, increase competitiveness, offer a diversified structure of products, invest in new contemporary software solutions that will allow reinforcement of their employees’ productivity and long-term reduction of the operating costs, as well.

    Full Text Available The article studies the development of the Far Eastern bioresource sector in 2006–2015 and its components: fishing industry, forestry and agriculture. It is shown that renewable bioresources, which form the foundation of the bioresource sector, are now becoming the limiting factor of that sector’s further extensive development which necessitates a transition to new ways and technologies of extracting and processing resources. The article attempts to identify and estimate the bioresource sector’s contribution to the economy of the Far Eastern Federal District (FEFD as a statistical unit through aggregating main macroeconomic indicators (gross added value, monetary value of exports, investments, number of employed, and tax revenue of its three components. The conclusion is that during the studied period the bioresource sector’s contribution to the economy of the FEFD has decreased mainly due to the factors of tax revenues and gross added value. The sector’s importance as source of employment in remote areas had also declined. At the same time the bioresource sector continues to significantly contribute to exports, mainly thanks to the fishing industry and agriculture. It is shown that the dominant role in the bioresource sector belongs to the fishing industry which increased its contribution to the bioresource sector and showed the most stable development compared to other components. The article studies changes in institutional conditions in all three components, their influence on the development of investments of the bioresource sector

    This research note analyzes differences in the number of absent working days and doctor visits and in their cyclicality between private sector, public sector and self-employed workers. For this purpose, I used large-scale German survey data for the years 1995 to 2007 to estimate random effects negative binomial (count data) models. The main findings are as follows. (i) Public sector workers have on average more absent working days than private sector and self-employed workers. Self-employed workers have fewer absent working days and doctor visits than dependent employed workers. (ii) The regional unemployment rate is on average negatively correlated with the number of absent working days among private and public sector workers as well as among self-employed men. The correlations between regional unemployment rate and doctor visits are only significantly negative among private sector workers. Copyright © 2012 John Wiley & Sons, Ltd.

  1. Chilly dark sectors and asymmetric reheating

    International Nuclear Information System (INIS)

    Adshead, Peter; Cui, Yanou; Shelton, Jessie

    2016-01-01

    In a broad class of theories, the relic abundance of dark matter is determined by interactions internal to a thermalized dark sector, with no direct involvement of the Standard Model (SM). We point out that these theories raise an immediate cosmological question: how was the dark sector initially populated in the early universe? Motivated in part by the difficulty of accommodating large amounts of entropy carried in dark radiation with cosmic microwave background measurements of the effective number of relativistic species at recombination, N eff , we aim to establish which admissible cosmological histories can populate a thermal dark sector that never reaches thermal equilibrium with the SM. The minimal cosmological origin for such a dark sector is asymmetric reheating, when the same mechanism that populates the SM in the early universe also populates the dark sector at a lower temperature. Here we demonstrate that the resulting inevitable inflaton-mediated scattering between the dark sector and the SM can wash out a would-be temperature asymmetry, and establish the regions of parameter space where temperature asymmetries can be generated in minimal reheating scenarios. Thus obtaining a temperature asymmetry of a given size either restricts possible inflaton masses and couplings or necessitates a non-minimal cosmology for one or both sectors. As a side benefit, we develop techniques for evaluating collision terms in the relativistic Boltzmann equation when the full dependence on Bose-Einstein or Fermi-Dirac phase space distributions must be retained, and present several new results on relativistic thermal averages in an appendix.

    In a broad class of theories, the relic abundance of dark matter is determined by interactions internal to a thermalized dark sector, with no direct involvement of the Standard Model (SM). We point out that these theories raise an immediate cosmological question: how was the dark sector initially populated in the early universe? Motivated in part by the difficulty of accommodating large amounts of entropy carried in dark radiation with cosmic microwave background measurements of the effective number of relativistic species at recombination, N eff , we aim to establish which admissible cosmological histories can populate a thermal dark sector that never reaches thermal equilibrium with the SM. The minimal cosmological origin for such a dark sector is asymmetric reheating, when the same mechanism that populates the SM in the early universe also populates the dark sector at a lower temperature. Here we demonstrate that the resulting inevitable inflaton-mediated scattering between the dark sector and the SM can wash out a would-be temperature asymmetry, and establish the regions of parameter space where temperature asymmetries can be generated in minimal reheating scenarios. Thus obtaining a temperature asymmetry of a given size either restricts possible inflaton masses and couplings or necessitates a non-minimal cosmology for one or both sectors. As a side benefit, we develop techniques for evaluating collision terms in the relativistic Boltzmann equation when the full dependence on Bose-Einstein or Fermi-Dirac phase space distributions must be retained, and present several new results on relativistic thermal averages in an appendix.

  4. Private sector joins family planning effort.

    Projects supported by the Directorate for Population (S&T/POP) of the U.S. Agency for International Development and aimed at increasing for-profit private sector involvement in providing family planning services and products are described. Making products commercially available through social-marketing partnerships with the commercial sector, USAID has saved $1.1 million in commodity costs from Brazil, Dominican Republic, Ecuador, Indonesia, and Peru. Active private sector involvement benefits companies, consumers, and donors through increased corporate profits, healthier employees, improved consumer access at lower cost, and the possibility of sustained family planning programs. Moreover, private, for-profit companies will be able to meet service demands over the next 20 years where traditional government and donor agency sources would fail. Using employee surveys and cost-benefit analyses to demonstrate expected financial and health benefits for businesses and work forces, S&T/POP's Technical Information on Population for the Private Sector (TIPPS) project encourages private companies in developing countries to invest in family planning and maternal/child health care for their employees. 36 companies in 9 countries have responded thus far, which examples provided from Peru and Zimbabwe. The Enterprise program's objectives are also to increase the involvement of for-profit companies in delivering family planning services, and to improve the efficiency and effectiveness of private volunteer organizations in providing services. Projects have been started with mines, factories, banks, insurance companies, and parastatals in 27 countries, with examples cited from Ghana and Indonesia. Finally, the Social Marketing for Change project (SOMARC) builds demand and distributes low-cost contraceptives through commercial channels especially to low-income audiences. Partnerships have been initiated with the private sector in 17 developing countries, with examples provided from

    for voltage support of each generator is formed by a fixed and a variable cost. The fixed cost is calculated from the annual recovery factor of the capital invested in the generator. The variable cost depends on the operation conditions and on the cost for loss of opportunity of the generator. To determine the total cost for the voltage support of generators, it is considered that the market of active power has already been solved previously through an economic dispatch of active power. The systems used for the evaluation of the developed program are: a 5 nodes system and the IEEE 30 nodes system. [Spanish] Los cambios en las estructuras de los sistemas electricos de esquemas verticales a esquemas horizontales ha provocado que los sistemas esten formados por cuatro segmentos: generacion, transmision, distribucion y comercializacion. Bajo este esquema el operador del sistema es el encargado de administrar y operar de manera economica y segura al sistema. Una de las tareas principales de esta organizacion junto con la red de transmision es la de realizar el movimiento de potencia desde los centros de generacion hasta los puntos de consumo, no obstante para poder llevar a cabo esta actividad se necesita un conjunto de servicios auxiliares. En un esquema horizontal, el soporte de voltaje por parte de los generadores es considerado como un servicio auxiliar, el cual es necesario para la operacion del sistema. Si bien la compensacion de potencia reactiva en un sistema electrico se debe realizar de manera local a traves de compensacion en derivacion, compensadores estaticos, condensadores sincronos y transformadores con cambiador en derivacion bajo carga, debido a que el transmitir flujos de potencia reactiva desde los generadores provoca un incremento en las perdidas del sistema de transmision; sin embargo aunque la funcion principal de los generadores sincronos es la produccion de potencia activa, de manera implicita estos generan potencia reactiva bajo ciertas condiciones

    Full Text Available In the post-war period the banking system in Poland underwent two important system transitions: after 1946 and after 1989. The third transformation began after May 1, 2004, but it did not have a systemic character. The Polish banking sector started to operate on the Single European Market. The first part of the paper is devoted to the problems of the banks transformations after 1989 with a special focus on the quantitative development of banks in 19892008, and on subsequent privatisation and consolidation processes. The former intensified in 19891999, and the latter in 19992002. The consolidation process was very noticeable in the sector of cooperative banks after 1994. The second part of the paper includes an economic and financial analysis of the banks. A lot of attention was paid to the liquidity of the banking sector. It was assessed as good, which was confirmed by a short-term rating of Moodys and by the Financial Stability Report 2009, published by the National Bank of Poland in June 2009. The comparison of the net profit of the banking sector in 19972008 shows its dependence on the economic situation and policy. The number of banks with capital adequacy ratio well above the minimum required by the banking supervision is rising. The financial power ratings are not favorable for the domestic banks. The third part of the paper focuses on the development directions of the Polish banking sector. It may be concluded on the basis of the analysis that privatisation and consolidation processes will be continued. They will concentrate on the capital of foreign banks already operating in Poland. As compared with individual foreign banks, the potential of the Polish banking sector is week. The fourth part of the paper focuses on the presentation Polish banking sector in the context of European Union banking sector. The paper finishes with conclusions. Generally, Polish banks have to implement a strategy to enable them to compete on the Single

    1999-01-01

    An overview of Mexico's energy sector was presented, with particular focus on the natural gas and electricity sectors. Mexico ranks fifth in oil production, eighth in proven oil reserves, and fourteenth in natural gas reserves. In 1998, the energy sector generated 3.3 per cent of Mexico's gross domestic product (GDP), and oil accounted for 7.5 per cent of total exports. National production of natural gas has been forecasted to grow at a rate of 5.2 per cent annually over the next 10 years. This will be largely due to the increased demand for natural gas to produce electricity. The Mexican government has also taken initiatives to restructure the Mexican energy sector with particular focus on increasing the competitiveness of the electric power industry. Electricity demand is also expected to grow at a rate of 6 per cent annually over the next six years. The objectives of energy reform are to promote more investment from all sectors in order to strengthen the development of the electric power industry and to provide a reliable, high quality service at competitive prices. 9 figs

    Nuclear industry is the 3. industrial sector in France and is the good reason why the French energy mix is largely carbon-free. The medium term challenges that faces nuclear industry in this country is first to succeed the extensive refit of nuclear power plants with a view on getting the extension of their operating life and secondly to recruit the skilled staff nuclear industry needs. About 8000 jobs dispatched in the 2500 enterprises that forms the nuclear sector will be available each year up to 2020. The age pyramid shows that numerous retirements are expected in the years to come so the issue of skill and knowledge transfer is looming. 25% of recruitment will be made on the basis of work-study contracts particularly for technical jobs. Concerning recruitment, the nuclear sector is competing with other high-tech sectors like aeronautics or the automobile sector, which make things harder. The image that nuclear industry wants to promote of itself is the image of a young, modern, high-tech industry that appeared less than 50 years ago and whose main purpose is to provide a carbon-free electricity to an avid world.

    The Directorate General for Environment of the European Commission has launched a study on the 'Sectoral costs of environmental policy'. The overall aim of the study is to obtain a clearer picture of the impact of environmental policy in some of the industrial sectors most affected by environmental policy, taking into account the differences between sectors and Member States. Previous studies mainly focussed on the individual impact of one Directive, but in this study we will assess the cumulative costs attributable to the environmental policy in its entirety and attempt to identify synergies between individual policies. The project has the following main objectives: paint a clearer picture of the environmental costs for the selected industries; indicate the differences in costs between individual companies; indicate the differences in costs between Member States; demonstrate the drivers for environmental expenditures of the companies and differences between sectors and Member States; describe different types of environmental regulation (policy instruments) and their impact on environmental expenditures; evaluate the environmental performance of the industries and differences between companies/Member States; collect evidence for the impacts of environmental regulation (and associated costs) on the competitiveness of companies; and carry out an international comparison. The sectors selected are:oil supply chain; electricity production; steel industry; and textile and leather industry

    Corruption is one of several factors that may hinder the access to pharmaceuticals. Since Kuwait has the highest per-capita spending on pharmaceuticals in the region, we wanted to evaluate the level of transparency in its pharmaceutical sector using an established assessment tool adapted by the World Health Organization. Standardized questionnaires were conducted via semi-structured interviews with key informants to measure the level of transparency in eight functions of the public pharmaceutical sector. The scores for the degree of vulnerability to corruption reflected marginal to moderate venerability to corruption for most pharmaceutical sectors. The perceived strengths included availability of appropriate laws, the presence of clear standard operating procedures, and the use of an efficient registration/distribution system. Weaknesses included lack of conflict of interest guidelines and written terms of reference, absence of pharmacoeconomic studies, and inconsistencies in law enforcement. Findings reveal that few functions of Kuwait pharmaceutical sector remain fairly vulnerable to corruption. However, the willingness of Kuwait Ministry of Health to adopt the assessment study and the acknowledgement of the weaknesses of current processes of the pharmaceutical sector may assist to achieve a transparent pharmaceutical system in the near future.

  13. Public Sector Wage Growth in Alberta

    2012-01-01

    Full Text Available In recent years, Alberta’s fiscal stance has shifted from large surpluses to deficits, and a large part of the blame appears to be due to rising public sector salaries. Since 2000, the province’s public sector wage bill has shot up by 119 percent — almost double the rate of growth in the rest of Canada. Wages, previously roughly at par with the rest of the country, are now higher (in many cases very substantially across all public sector categories, including health care, social services, education and government, consuming 95 percent of the increase in provincial revenues over the past decade. At the same time, the number of public sector employees has grown faster than the overall population; it is difficult to attribute this sharp uptick to a rise in productivity, or the need to compete with private industry for skilled workers. This paper breaks down the increases in every category, arguing that if the provincial government is looking to trim expenditures, public sector salaries are a good place to start. The authors make their case using detailed Statistics Canada data, throwing down the gauntlet to defenders of the status quo and challenging them to justify these disparate increases.

    Full Text Available The study seeks to assess the structure of the economy of Ghana in terms of changes in the economic structure before and after the production of oil in commercial quantities. This is viewed with regards to economic multipliers, sectoral interdependence and trade concentration. The results show that changes occurred with regards to multipliers and sectoral interdependence. The output multipliers of most sectors have declined. The results also show that the agricultural sector experienced an initial decline in its growth while industry experienced an increase. The performance of the services sector was relatively stable for the period covered by the study. There is a decline in the level of trade concentration though on a whole the concentration index is still high. The study employed input-output modeling techniques and the data was obtained from the Ghana statistical service and the World Development Indicators.

    As the changes underpinning the Coordinated Care Trials in South Australia have become more apparent, similarities have emerged between the rationalisation of public schooling in the mid 1980s and the transformation of public health in the 1990s. This article aims to discuss the evolution of health services in South Australia and help us answer the question of how best to manage our public and private health infrastructure in a changing economic and social context. Both strategies in education and health share common elements of cost cutting, attempts at improving efficiencies, a flirting with the private sector and the attendant risk of reduced quality of services to the public. This situation in both sectors is indicative of a shift in public policy and a growth in the belief that private management of public sector infrastructure can help resolve the funding crises around our education and health systems.

  9. Environmental consequences of electricity sector reforms

    Wohlgemuth, N.

    1999-01-01

    Worldwide, the electricity industry is in the process of undergoing fundamental transitions. The reform process typically involves one or more of the following changes: commercialisation, privatisation, unbundling/restructuring and introduction of competition. The environmental impacts of these changes pull in different directions. There is concern that restructured electricity markets may not always incorporate adequately the environmental impacts of electricity resource development and consumption decisions. However, the electricity sector reform process also offers an opportunity to promote positive environmental changes: because the sector is already in flux, it may be easier to address environmental issues. The paper gives an overview of power sector reform in six countries where reforms have already been implemented, and concludes that reform measures will have to be accompanied by competitively neutral regulations in order to stimulate investment in environmentally sound technologies, including renewable and energy efficient technologies.

    2011-07-01

    We consider an international emissions trading scheme with partial sectoral and regional coverage. Sectoral and regional expansion of the trading scheme is beneficial in aggregate, but not necessarily for individual countries. We simulate international CO{sub 2} emission quota markets using marginal abatement cost functions and the Copenhagen 2020 climate policy targets for selected countries that strategically allocate emissions in a bid to manipulate the quota price. Quota exporters and importers generally have conflicting interests about admitting more countries to the trading coalition, and our results indicate that some countries may lose substantially when the coalition expands in terms of new countries. For a given coalition, expanding sectoral coverage makes most countries better off, but some countries (notably the USA and Russia) may lose out due to loss of strategic advantages. In general, exporters tend to have stronger strategic power than importers.(Author)

    Eighteen interplanetary sector boundary crossings observed at 1 AU during the period January 1971 to January 1974 by the magnetometer on the Imp 6 spacecraft was discussed. The events were examined on many different time scales ranging from days on either side of the boundary to high-resolution measurements of 12.5 vectors per second. Two categories of boundaries were found, one group being relatively thin (averaging approx. =10 4 km) and the other being thick (averaging approx. =10 6 km). In many cases the field vector rotated in a plane from polarity to the other. Only two of the transitions were null sheets. Using the minimum variance analysis to determine the normals to the plane of rotationa and assuming that this is the same as the normal to the sector boundary surface, it was found that the normals were close to ( 0 ) the ecliptic plane. The high inclination of the sector boundary surfaces during 1971--1973 verifies a published prediction and may be related to the presence of large equatorial coronal holes at this time. An analysis of tangential discontinuities contained in 4-day periods about our events showed that their orientations were generally not related to the orientations of the sector boundary surface, but rather their characteristics were about the same as those for discontinuities outside the sector boundaries. Magnetic holes were found in thick sector boundaries, at a rate about 3 times that elsewhere. The holes were especially prevalent near stream interfaces, suggesting that they might be related to the convergence and/or slip of adjacent solar wind streams

    The purpose of the present study was to develop a method of determining market boundaries in preparation of identifying all the competitive forces which a company in the electricity sector must address and deciding on this basis whether it has a dominant position in the market. The study focused in particular on current developments in the German electricity sector, this being the only way to permit a demarcation that accurately reflects the true economic situation. First the question was addressed whether a determination of market boundaries is at all necessary for performing a competitive analysis and in what specific constellations they could play a role. Giving due consideration to the special features of the electricity sector the most preferable market demarcation methods were applied to individual areas of the electricity sector that are of competitive relevance. Efforts were directed at arriving at market boundaries most conducive to the goal of identifying those competitive forces which a company in the electricity sector must address. For this purpose a critical assessment was undertaken of established market demarcation practices in Europe and Germany in order to determine whether ''classical'' market demarcation methods could be applied or whether modifications were needed on account of special features of market structure. The author also describes and discusses alternatives to the established market demarcation methods. She also elucidates methods of determining the boundaries of markets that have emerged as a result of recent developments in the electricity sector, for example through the growth of electricity production from renewable resources, or which are still in the process of formation.

  13. What we know from epidemiological studies on cancer and residential exposure to radiofrequency fields Qué sabemos a partir de los estudios epidemiológicos sobre la exposición residencial a ondas de radiofrecuencia y su relación con el cáncer

    Full Text Available This review discusses epidemiological studies on residential exposure to radiofrequency fields and its possible association with cancer are commented. Most of these studies are ecologic. They use the distance to the power station as a surrogated measure of exposure. Possible confounders other than sex and age are rarely considered. For these reasons, it is difficult to infer causality from their results. Very often the study was a carried out due to the observation of cluster of cancer cases. Some of these clusters were reanalysed yielding different conclusions, showing their methodological weakness.En esta revisión se presentan y comentan los estudios existentes sobre la exposición residencial a campos de radiofrecuencia con relación a un posible aumento de incidencia o de mortalidad por cáncer. La mayor parte de estos estudios son de naturaleza ecológica, con una medida de exposición indirecta: la distancia a las antenas. El control de posibles factores de confusión más allá de la edad y el sexo es bastante limitado. Por estas razones, los resultados de estos estudios no tienen una fácil interpretación causal. Muchas veces el estudio fue motivado por la aparición de una agregación inusual de casos de cáncer. Algunos de estos clusters fueron reanalizados llegando a conclusiones diferentes, lo que demuestra la debilidad metodológica de este tipo de estudios.

    This paper reports that the Philippines' downstream sector is poised for sharp growth. Despite a slip in refined products demand in recent years, Philippines products demand will rebound sharply by 2000, East-West Center (EWC), Honolulu, predicts. Philippines planned refinery expansions are expected to meet that added demand, EWC Director Fereidun Fesharaki says. Like the rest of the Asia-Pacific region, product specifications are changing, but major refiners in the area expect to meet the changes without major case outlays. At the same time, Fesharaki says, push toward deregulation will further bolster the outlook for the Philippines downstream sector

    The future of Ontario Hydro and the provincial electrical sector was discussed. Various models proposed for restructuring Ontario's electric sector were described and views of some of the stake holders were presented, among them the views of AMPCO, MEA, the Ontario Chamber of Commerce, IPPSO, Ontario Hydro Management, Energy Probe and the Power Workers' Union. In general, most stake holders were in favour of privatization to some degree except for the Power Workers' Union which was unalterably opposed to privatization, claiming that it would lead to quantum increases in electricity rates. 2 figs

    Simulation results are presented on Higgs mass calculations in the spontaneously broken phase of the Higgs sector in the minimal Standard Model with a higher derviative regulator. A heavy Higgs particle is found in the TeV mass range in the presence of a complex conjugate ghost pair at higher energies. The ghost pair evades easy experimental detection. As a finite and unitary theory in the continuum, this model serves as an explicit and simple example of a strong interacting Higgs sector without technicolor. (orig.)

    The Atomiki anomaly can be interpreted as a new light vector boson. If such a new particle exists, it could be a mediator between the Standard Model sector and the dark sector including the dark matter. We discussed some simple effective models with these particles. In the models, the secluded dark matter models are good candidates to satisfy the thermal relic abundance. In particular, we found that the dark matter self-interaction can be large enough to solve the small scale structure puzzle...
