    1996-07-01

    The electric power system management in Costa Rica is analyzed. The possibility of substitution of LPG (Liquefied Petroleum Gas) for electric power, in home cooking, are identified as one of the most important program in order to reduce increasing load peak and energy requirements in electric power system of Costa Rica. The sustain ability of the substitution program stands on the current process of electric power supply. The primary power sources used in generating electric power in rush hours are oil-based; this process is less efficient than directly using LPG for home cooking. Large scale substitution with LPG in home cooking will reduce increasing electric power demand in peak hours, reducing subsidized electricity sales, with better use of combustibles presently imported, improving the country commercial balance and preventing or postponing electric power system expansion investments. Three different perspectives have been considered in evaluating economical effectiveness in substituting power sources: user, utility and society perspectives. Due to subsidized electric power prices, residential users do not enough interest in substituting of LPG for power source; unless LPG cookers are also subsidized. However, positive results for the distribution utility are enough in order to offer these kind of incentives. Explicit treatment of these kind of programs, including the efficiency increment as an available resource for electric power utilities in Costa Rica, will avoid the implantation of most of combustion plants now planned in current National Electric Power Plant expansion program.

    A series of lagoons can be found along the coastline of Rio de Janeiro, in the so-called Regiao dos Lagos. The lagoons differ in size, physicochemical, sedimentological and biological characteristics. Rare examples of litifying microbialites that produce stromatolites, the oldest fossils on Earth, can be found living in this lagoon system. The occurrence of stromatolites in the region is of great scientific interest because it enables the study of possible analogues of the earliest life on Earth. However, this region has been suffering from intense human activities and degradations. Geoconservation planning requires an assessment of the characteristics of the region and its potential threats. The primary goal of this study is to assess physical environmental changes and anthropogenic impacts over the last four decades in Regiao dos Lagos. Using a broad integrative assessment combining remote sensing, GIS, field studies and local knowledge of communities, land-cover and land-use classes were identified, as well as the main human activities impacting the environment. The seasonal and weekend tourism and urban sprawl in this coastal area of Rio de Janeiro triggers the occupation of new areas and the removal of natural vegetation, especially on lagoon margins. This disorderly occupation by an ever increasing population, with both legal and illegal constructions and the subsequent overload of the local infrastructure, e.g. increase of electrical energy consumption, volume of vehicles, pollution in air, water and soil and problems with water supply and wastewater treatment, are hastening the gradual degradation of the lake ecosystem. The main driving forces to environmental changes over the last four decades in Regiao dos Lagos were the change of dense vegetation, saline and bare soil classes into built-up areas, adding to the poor waste treatment and inadequate sewage disposal. This analysis provides a basis for a better control of anthropogenic impacts and

    Full Text Available The industrialization of components and constructive systems for the construction of housing buildings is the main purpose of this paper. Based on analyses of traditional constructive systems, the article evaluates the economic and technical possibilities of the contemporary industry. This new technology should improve the processes of production and construction and become the specialization of the building sector. Finally in order to achieve the improvement of housing construction in Spain, industrialization has to solve the new challenges of contemporary society as water and energy consumption, working safety… This architectural approach is illustrated by 3 projects designed and built according to contemporary industrial methodologies. This selection represents the most common housing typologies in our country, and demonstrates that industrial approach can be a response in a wide range of housing applications. These study cases are characterized by: – Low height building as multifamily dwelling. Development of an industrialized structural system composed by three-dimensional modules as support of precast floors. – High height building as multifamily dwelling. development of an industrialized structural system for an eight stories building. – Single-family house. Development of an innovative typology of industrialized bioclimatic dwelling.En este artículo se aborda la temática de industrialización de componentes y sistemas constructivos, destinados a la edificación residencial.

    2012-05-01

    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.

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.

  13. Componentes sociales y espaciales de la movilidad residencial en Bogotá.

    Directory of Open Access Journals (Sweden)

    Daniel Delaunay

    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.

  14. Groundwater radon, radium and uranium concentrations in Regiao dos Lagos, Rio de Janeiro State, Brazil

    Almeida, R.M.R.; Lauria, D.C.; Ferreira, A.C.; Sracek, O.

    2004-01-01

    Ground water from Regiao dos Lagos, a coastal area of Rio de Janeiro state, was analysed for 226 Ra, 228 Ra, 222 Rn, 238 U, major ion concentrations, and physico-chemical parameters were also measured. Concentrations values ranged from -1 for 226 Ra, from -1 for 228 Ra and from -4 to 8.0x10 -2 Bq l -1 for 238 U. Detectable 222 Rn concentrations (>3 Bq l -1 ) were found only in two samples. The spatial distribution of Ra concentration delineated one distinct area and some hot spots with high Ra concentration. Low pH value is the most important water parameter linked to high radium concentration. This is probably related to limited adsorption of radium on soil ferric oxides and hydroxides at low pH range. There was a significant correlation between uranium concentrations and electrical conductivity values, and also between uranium concentrations and concentrations of Ca, Mg, Na, K, and Cl, indicating sea water impact. Uranium concentrations were lower than maximum contaminant level for drinking water, whereas 17 out of the 88 ground water samples had levels of radium that exceeded the maximum contaminant level for tap water. The total annual effective dose for adult due to the water consumption reaches values up to 0.8 mSv

    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

    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.

    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.

    The main objective of this paper is to make an historical revision and analyze the current condition of the electric tariffs in the Mexican residential sector and ask ourselves if the equalization of tariffs generates the possibility that the entire population has access to the electricity service. The document is divided into three parts. The first one presents the history and the tendencies of the tariffs in the domestic sector in Mexico since 1973 until 1996 and the current tariff structure. The second one describes the characteristics of the residential users and mention is made of how the increment of the electric tariffs would affect the various population sectors. The last part of this paper presents some tariff criteria, that take into account energy conservation measures [Espanol] El objetivo principal de este trabajo es hacer una revision historica y analizar la situacion actual de las tarifas electricas en el sector residencial mexicano y preguntarnos si la igualdad de tarifas genera la posibilidad de que toda la poblacion tenga acceso al servicio electrico.

    Full Text Available El aumento de la esperanza de vida, los cambios sociales y los cambios en la estructura familiar hacen que cada vez sean más y durante más tiempo las personas mayores que prefieren vivir solas, incluso cuando necesitan cuidados. Este trabajo tiene como objetivo describir el problema de la soledad residencial de las personas mayores profundizando en los factores que pueden influir en esta circunstancia. Se ha realizado una estrategia de búsqueda bibliográfica a partir de los conceptos nucleares: "personas mayores de 75 años que viven solas", "persona mayor frágil", "soporte social y entorno", "nivel de instrucción" y "familia". La información recopilada de las aportaciones científicas realizadas en este campo pone de manifiesto la necesidad de considerar prioritario conocer la opinión de las personas mayores y sus familias sobre los factores que modifican la permanencia en el domicilio.

    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.

    2005-12-01

    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

This article begins with the description of its main characteristics, its effects at a local level and the different phases of its evolution. A special reference will be made with regard to last phase (2002-2007 which has been nomitaded New Residential Tourism (NRT. NRT is characterized by the appearance of urban megaprojects of thousands of households, with several golf courses and all the services needed. Its goal is to build privatized units of residential leisure, which are autonomous and independent from the territory where they are settled.

    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.

    Full Text Available This article aims at fulfilling three objectives. 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.

    Full Text Available El presente artículo es resultado de un trabajo de tesis para la obtención del título de licenciatura. 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.

Este trabajo explora mediante el método estadístico de Regresión Lineal Multivariada los principales determinantes de la percepción individual de seguridad. Esta metodología se aplica con una perspectiva multinivel que considera el nivel de determinantes individuales (sexo, edad, años de educación, ingreso del hogar, como el nivel de determinantes de las relaciones sociales y del territorio residencial del individuo. Los resultados a nivel de variables individuales son coherentes con la evidencia previa. Diversas variables asociadas a la interacción social en el barrio inciden en la percepción de seguridad. En particular, con¿ anza e interacción entre vecinos junto a la antigüedad de los barrios son relevantes en la determinación de la percepción de seguridad. El rol de las señales de desorden físico no parece relevante. La presencia de programas de seguridad ciudadana a nivel municipal en el territorio es signi¿ cativa, indicando la relevancia de estas iniciativas en frenar el temor de las comunidades.

    Full Text Available This article studies the importance of international theoretical and empirical analyses in order to explain residential segregation of foreign immigrants in one of the most multi-ethnic areas of Spain, the province of Almería. To find out the processes leading to segregation, we have analysed urban growth and the context of reception as the key elements in designing immigrant incorporation. The results show that the main cause of segregation is ethno-discrimination based on native residential preferences for the endogroup.

En este artículo se analiza la ciudad como parte de un devenir histórico-político particular, desde un enfoque multidimensional en el que se hace especial énfasis en la relación establecida entre las divisiones territoriales internas y el componente migratorio de la población. San Carlos de Bariloche (Patagonia argentina posee una heterogénea composición étnico-cultural, fruto de diversos flujos migratorios internos e internacionales. Profundas y complejas distancias materiales y simbólicas separan la ciudad turística (la "Suiza argentina" asociada a una elite nutrida por migrantes internos urbanos y europeos, de la ciudad de "El Alto", donde migrantes internos rurales y chilenos se han asentado en barrios populares. La relación clase-origen se entrelaza en una división social del espacio residencial, que se profundiza y produce segregación urbana y refuerza las tensiones.

    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.

Entre los hallazgos más destacables, se encuentra la correspondencia con las tendencias de la segregación residencial en otras ciudades latinoamericanas: una mayor segregación a escala menor y una disminución en el tiempo de los niveles de la segregación. Asimismo, la Gran Área Metropolitana (GAM en general presenta menores índices de segregación que varias ciudades latinoamericanas, particularmente Santiago de Chile, diferencia que se explica por el origen y la estructuración histórica de la ciudad, pues la GAM se caracteriza por ser un espacio urbano menos polarizado, más heterogéneo, con una concentración de las élites en áreas pequeñas distribuidas por toda la ciudad y una distribución más bien dispersa de una amplia clase media.

    2013-09-01

    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.

    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.

    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. [Espanol] Este articulo analiza los cambios en el equipamiento de las viviendas y en el consumo de energia residencial por usos finales en Mexico en la decada 1984-1994. El estudio se basa en datos de la Encuesta Nacional Ingreso-Gasto de los Hogares del Instituto Nacional de Estadistica, Geografia e Informatica (INEGI) y en estimaciones del consumo unitario de los equipos. Los resultados mas importantes muestran que la coccion de alimentos representa el 64% del consumo de energia residencial, 22% el calentamiento de agua, 4% la iluminacion y 10% los equipos electricos y otros usos de gas LP y gas natural. Los equipos de mayor saturacion en 1994 fueron la estufa de gas (87%), la plancha (85%), la television (85%) y el refrigerador (64%). En un analisis de equipamiento por nivel de ingreso, se muestra que existe una inequidad grave en el pais. El numero de viviendas que cuentan con equipos para suministrar servicios energeticos depende enormemente del nivel de ingreso de las mismas.

    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.

    2015-01-01

    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.

    Full Text Available Esta investigación presenta el diseño e implementación de una “Automatización de Procesos en la Administración de Energía Eléctrica” (APAEE en el área residencial. El sistema consiste en un software de administración de energía eléctrica que funciona en una computadora de control central que se conecta a través de una red inalámbrica bajo el estándar IEEE 802.15.4 y una topología en malla a dispositivos remotos encargados de controlar los servicios de iluminación y climatización en una residencia en función del consumo de electricidad y parámetros establecidos por los usuarios. El hardware está basado en microcontroladores AVR® XMEGA® de la marca Atmel®. Un estudio en los patrones de consumo de electricidad en una residencia es llevado a cabo en el desarrollo de los algoritmos de control, por medio de la instalación de sensores que detectan presencia de personas y estado de conmutación tanto de lámparas como del ventilador y compresor en acondicionadores de aire. En base a los resultados obtenidos, el diseño y simulación de los algoritmos de control han de ser realizados en Matlab® para posteriormente ser implementados en el software de control. El desarrollo de la APAEE reducirá considerablemente el consumo de electricidad en el área residencial.

    Full Text Available Este estudio es parte de una investigación más amplia sobre la puesta en marcha del plan de formación para los jóvenes protegidos en acogimiento residencial: «Plan de Preparación para la Vida Autónoma 16-21 años». 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 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

    Directory of Open Access Journals (Sweden)

    Maria Conceição Barletta Scussel

    Full Text Available Num contexto global de urbanização crescente e de transformações acentuadas no espaço das cidades, destacam-se os processos peculiares à dinâmica das grandes cidades brasileiras, que alteram substancialmente sua configuração, promovendo rupturas no tecido urbano consolidado e nas práticas de apropriação e uso desse espaço, comprometendo sua sustentabilidade. A partir dessa perspectiva, o objetivo do presente trabalho é analisar o impacto do processo de verticalização e adensamento na qualidade do espaço residencial de um bairro de Porto Alegre (RS, promovido por alterações na legislação urbanística. Mediante estudo de caso, realizou-se análise comparativa de diferentes quarteirões, utilizando-se método de avaliação da Qualidade do Espaço Residencial (QER. Os procedimentos adotados incluem a análise de documentos, levantamentos a campo e observação direta. Apresentam-se os resultados da aplicação do método de avaliação QER, em termos de qualidade do espaço da habitação, qualidade do contexto da habitação, qualidade do espaço dos serviços, qualidade dos percursos casa / serviços, apontando diferenças significativas entre quarteirões que sofreram verticalização acentuada e quarteirões que mantiveram a tipologia original. A principal contribuição deste artigo reside em explorar o potencial de uso da ferramenta QER para ilustrar o impacto da aplicação de legislação urbanística, instrumentando a discussão do modelo espacial de desenvolvimento da cidade.

    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.

    Full Text Available Desde o período do pós-guerra, a discussão sobre fatores que exercem impacto sobre a produção e reprodução de desigualdades sociais e educacionais oscilou entre explicações otimistas sobre a expansão dos sistemas escolares e outras que concedem peso à origem socioeconômica dos alunos e/ou a fatores relacionados a processos escolares. O artigo discute a tradição de estudos quantitativos que tiveram origem no Relatório Coleman (1966 e seus desdobramentos nos estudos de efeito escola e, posteriormente, de efeito vizinhança. Concentra sua análise nos limites e possibilidades trazidos pela literatura de efeito vizinhança e da geografia de oportunidades para a compreensão de mecanismos mediadores entre a segregação residencial e resultados escolares. Discute estudos que partiram desse arcabouço teórico e metodológico, focalizando o contexto brasileiro. Pontua os próximos desafios para se avançar na compreensão da organização social do território e as desigualdades educacionais nesse contexto.

    Full Text Available Como representam as crianças os bairros onde vivem foi a questão orientadora a que a pesquisa apresentada neste artigo procurou responder, com base numa técnica visual (desenho e tendo por contexto seis bairros de realojamento na área metropolitana de Lisboa, Portugal. Na análise das perceções de 312 crianças sobre os bairros, observa-se que a segregação residencial é representada como uma forma de violência: física, pelas limitações que impõe; simbólica, pelos efeitos nas relações sociais. As lógicas de segregação territorial e as dinâmicas sócio espaciais estruturam as relações entre pares e com adultos e a etnização dos laços e redes sociais das crianças, manifestada em várias formas de discriminação relativamente a outros grupos, é um fenômeno multidirecional.

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.

  6. Análise de dados de reclamações em empreendimentos habitacionais de interesse social: estudo no Programa de Arrendamento Residencial

    Full Text Available O gerenciamento de reclamações é uma prática difundida em muitas emmpresas do setor de manufatura, a fim de proporcionar a melhoria da ualidade de produtos e serviços. No que tange à construção civil, bservam-se poucos estudos sobre a utilização desse tipo de gestão de empreendimentos, sendo poucas as empresas que percebem a utilidade das informações sobre reclamações. O presente trabalho apresenta uma análise de dados de reclamações de usuários de uma amostra de empreendimentos habitacionais de interesse social, com o objetivo de investigar sua utilidade para a retroalimentação do processo de desenvolvimento do produto nesse segmento. Foram analisadas 6.956 reclamações de usuários de 42 empreendimentos habitacionais de interesse social do Programa de Arrendamento Residencial, localizados no estado do Rio Grande do Sul. O trabalho envolveu um tratamento inicial dos dados de reclamações para a montagem de um banco de dados, seguido da aplicação de diversos testes estatísticos. As principais contribuições estão relacionadas com a utilidade dos dados de reclamações, incluindo a geração de indicadores que podem apoiar a tomada de decisão por parte de diferentes agentes envolvidos na produção habitacional, tais como projetistas, construtoras, agentes financiadores e empresas envolvidas na gestão da operação e manutenção. Os indicadores, se bem utilizados, podem contribuir para a melhoria de produtos e serviços que compreendem os empreendimentos habitacionais, possibilitando um aumento na satisfação dos usuários finais.

    Full Text Available El patrón de segregación residencial de las ciudades chilenas se está transformando en dos sentidos principales: está cambiando su escala geográfica y está aumentando su malignidad. 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. They are linked to the land markets’ liberalization policies and to the processes of economic and cultural globalization of the past decades. This paper presents empirical data showing the effects of these changes for three Chilean cities (Santiago, Valparaíso, Concepción; and theoretically discusses the relationship between social inequality and spatial segregation, rejecting the usual approach that considers the latter as a mere spatial reflection of the first

    Full Text Available La transición demográfica ha derivado en el progresivo envejecimiento de las poblaciones de los países de América Latina y el Caribe. 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.

    2018-01-01

    Full Text Available Este estudio indaga el grado de segregación residencial en los municipios que han albergado la construcción de 121 conjuntos de vivienda social, edificados en el arco nororiente del Valle de México durante el decenio 2000-2010, así como las variaciones en el grado de accesibilidad de los propios conjuntos urbanos en el mismo periodo. Mediante indicadores de accesibilidad, de autocorrelación espacial, y la contabilización de la oferta y demanda de vivienda social, se concluye que existe un alto grado de segregación en estos conjuntos residenciales y los municipios que los albergan con respecto a los municipios centrales del Valle de México; que esta segregación tiende a reducirse mínimamente con el paso del tiempo para algunas de las variables estudiadas; y que la sobreoferta de vivienda social puede haber favorecido la segregación residencial en escala metropolitana.

  11. Desigualdades de oportunidades e segregação residencial: a metropolização da questão social no Brasil

    Directory of Open Access Journals (Sweden)

    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.

Estas actividades atrajeron a migrantes de otras provincias argentinas y del sur de Chile que ocupan acelerada y espontáneamente tierras fiscales, principalmente con viviendas uni y multifamiliares, en parcelas urbanas de dimensiones mínimas. Esta área residencial, densamente poblada, requirió del incremento de servicios y equipamiento básico de salud, educación, recreativo, deportivo, seguridad, de asistencia social, de sanidad, necesarios para el funcionamiento y atención de los habitantes. Estos equipamientos, dependientes algunos de la administración provincial, otros de la municipal, se localizan en parcelas cercanas que comprenden unas pocas manzanas, cuya concentración constituyen nodos de servicios que atraen otros usos como el comercial. Los nodos de servicios comprenden áreas de influencia delimitadas por el Estado municipal con diferente cantidad de población. De este modo este trabajo tiene como objetivo conocer de los nodos de servicios la relación entre la cantidad de la población de las áreas de influencia y la distribución espacial, para evaluar si los requerimientos de servicios básicos de la población de la segunda franja residencial están atendidos. Se destaca la importancia de los resultados que sirven de aporte para estudios referidos al diagnóstico territorial.

    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.

    Full Text Available O presente trabalho analisa a segregação residencial socioeconômica na cidade de Neuquén (Patagônia, Argentina no começo da década de 1990. Para cumprir com esse propósito, o texto divide-se em três partes. Na primeira seção, realiza-se uma aproximação teórico-metodológica ao conceito de segregação residencial e um levantamento de possíveis maneiras de medi-la. Na segunda parte, propõe-se uma descrição geral do cenário no qual se desenvolveu o fenômeno que pretendemos estudar. Para tanto, examina-se a estratégia de crescimento implementada pelo Governo Provincial e as mudanças que a mesma imprimiu na população e na sociedade de Neuquén. Na última parte do texto, apresenta-se uma análise quantitativa de três dimensões da segregação: desigualdade, concentração e isolamento. Em termos heurísticos, o artigo utiliza informação sociodemográfica fornecida pelo Censo Nacional de Población y Vivienda de 1991 da Argentina. Além disso, para espacializar muitos dos fenômenos que os dados censuais colocaram em evidência, elaboraram-se cartografias temáticas a partir da utilização de Sistemas de Informação Geográfica.

    Full Text Available Os sistemas de aproveitamento de água pluvial (SAAP para fins não potáveis em edificações representam uma das medidas para reduzir a demanda de água potável e minimizar os problemas relacionados à disponibilidade dos recursos hídricos. O trabalho avaliou a viabilidade técnica e financeira da implantação de um SAAP em um empreendimento residencial- em construção- na Região Metropolitana do Recife por meio de uma simulação, fazendo uso da água da chuva para fins não potáveis na rega de jardins. Para tal, realizou-se um estudo dos índices pluviométricos da região e sua periodicidade, avaliando-se os meses de maior e menor precipitação. O reservatório de armazenamento foi dimensionado por meio do método computacional Netuno e em diferentes cenários de área de captação, de maneira a avaliar a situação ideal para suprir a demanda mensal de água da rega dos jardins. A análise econômica da construção do sistema mostrou que a sua implantação em uma edificação residencial com características similares a utilizada no estudo é tecnicamente e economicamente viável.

    Full Text Available Resumo O presente trabalho insere na discussão dos espaços habitacionais oferecidos à população que recebe de 0 a 3 salários mínimos a emergência de estabelecimentos de comércio e de serviços. O objetivo principal desta pesquisa é compreender o papel social e espacial do setor terciário nos empreendimentos do programa Minha Casa, Minha Vida (PMCMV a partir de um estudo de caso realizado no Residencial Vista Bela, com 2.712 unidades, em Londrina, PR. Os instrumentos de coleta de dados abrangeram o monitoramento in loco de outubro de 2012 a julho de 2014 e a aplicação de dois questionários, o primeiro distribuído a 51 comerciantes, e o segundo, a 188 moradores. Verificou-se um aumento de 300% no número de unidades que agregaram comércio à residência em três anos. Os resultados proporcionam o entendimento da formação tanto da demanda como da oferta no mercado de bens do Residencial Vista Bela, bem como da estratégia para geração de renda. A pesquisa contribui para elucidar possíveis reavaliações da política habitacional e fomentar discussões a respeito do setor terciário em empreendimentos do PMCMV, a partir do entendimento das áreas de comércio e serviços como um dos componentes necessários ao habitar.

    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.

    Full Text Available Mediante un cuestionamiento a influyentes trabajos, se pretende introducir perspectivas alternativas en variados aspectos del estudio de la segregación residencial en Chile, desde esquemas metodológicos a interpretaciones conceptuales. 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.

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.

    Full Text Available RESUMEN Las complejas circunstancias que normalmente rodean la realización de una obra de arquitectura, dificultan la simultánea sistematización de la reflexión y la transferencia de la experiencia. 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.

    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.

    Full Text Available ResumenLa evolución social, funcional y morfológica de los tejidos industriales en las transformaciones urbanas recientes no ha sido un fenómeno destacado. 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. Se examinan dos estudios de caso ejemplares en detalle: el polígono Julián Camarillo en San Blas y el polígono Embajadores en Arganzuela.Palabras clave  Transformación de usos; tejidos industriales, cambios sociales, funcionales y morfológicos; regulación normativa; producción de vivienda.AbstractThe social, functional and morphological evolution of the industrial fabrics in the recent years hasn’t been a significant phenomenon in the academic literature. However, the urban land release has been an important factor as a renewal on land uses opportunity transforming the territory, introducing a combination of functions and activities on it by overlapping them and incorporating different densities among others. It has arisen great expectations both from an urban and economic side.  Different Management Plans all along these years have conditioned the process either by keeping the industrial activity or by transferring or closing the fabrics in order to replace them with new residential or service

    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.

    Full Text Available El sector residencial se presenta como el mayor consumidor de energía dentro del sector edilicio. Si bien en los últimos años se han incrementado las normativas/proyectos para establecer estrategias de uso racional y eficiente de la energía, aún se está en proceso. Este trabajo parte de la hipótesis que los usuarios son responsables del consumo energético no previsto durante el uso del edificio. El objetivo es validar una herramienta metodológica que exprese el Nivel de Eficiencia del Usuario (NEU de un edificio residencial en altura, ubicado en San Juan-Argentina. Para ello, se desarrolla un trabajo de campo mediante encuestas. Se relevan los hábitos que el usuario promedio emplea para satisfacer su condición de confort térmico en período cálido. Los resultados se traducen en una escala gráfica a modo de etiqueta. De la evaluación de los resultados se observa un empleo masivo de estrategias pasivas (no consumen energía por sobre aquellas de tipo activas, resultando un consumo de 14,6 kWh/m2.Persona. En correspondencia, el indicador NEU encontrado es del tipo “bueno”, y no tiene correlación con parámetros como edad del individuo, cantidad de personas por departamento o ubicación en altura, por lo que se concluye que es producto del nivel de conciencia sobre el uso racional de la energía (URE.

    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.

    La movilidad residencial es un fenómeno cada vez más habitual entre la población, y en particular en las personas de más edad. La jubilación suele ser un momento en el que cada vez más personas deciden cambiar su lugar de residencia. Se trata de una decisión que responde a factores de tipo social, económico y cultural, principalmente, aunque para su estudio también es necesario profundizar en otras razones de tipo geográfico, ambiental, familiar, social, cultural, etc. En este trabajo se analizan las razones que han impulsado a personas mayores residentes en Madrid a cambiar su lugar de residencia, bien de forma temporal o definitiva, para lo cual se ha trabajado con metodología cualitativa. Es necesario conocer bien esas razones, no sólo para planificar los futuros lugares de retiro, además de los servicios y equipamientos que tales desplazamientos requieren, sino también para contribuir a la mejora de la calidad de vida de estas personas.

  16. Impacto de la envolvente en la demanda de energía en calefacción residencial de la región metropolitana de La Plata, tomando como caso testigo el reciclado energético de una vivienda

    Directory of Open Access Journals (Sweden)

    María de la Paz Diulio

    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 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.

    The present paper study thermosyphons applied to bakery ovens with special attention in the energy conservation and the quality of final baked product. A prototype simulating one internal section of a commercial oven was built for the experimental study. Stainless steel/water thermosyphons are installed vertically, close to the two lateral walls of this section The thermosyphons are very efficient heat exchangers and improves the temperature distribution inside the oven, saving energy and avoiding the product waste by under or overcooking. This research also intends to replace electric power and GLP by natural gas as the energy source, that is available in the South of Brazil, after the recent implantation of the Brazil/Bolivia gas line. The gas combustion happens in a separated chamber, so that, just the heated air are in contact with be bread in the cooking chamber. The final product has better quality and is free from the combustion residues. (author)

    Amongst several exploratory sources of the subject 'hazardous materials transport', it is distinguished: 'the threat to the environment'. This paper presents an exploratory investigation of this subject line in the Amazon region. In view of the diversity of 'existing hazardous materials' and the raised dimension of the oil transport and its derivatives in this context, this paper focused in these products. Regarding to the geographic region, the approach was given to the State of Amazon, considering the amplitude of this State in the Amazon region and the availability of data. Therefore, this work explores and analyzes macro aspects inherent to the State of Amazon pertinent to the oil transport and its derivatives. In the macro context, it is observed the necessity of a higher control in the transport of hazardous materials in the region. The absence of registered data and the unfamiliarity on the risks related to the transport of hazardous materials by authorities and transporters indicate a relative absence of qualification in the region to deal with the monitoring of the transport of hazardous materials. So far, it is not possible up till now to make any evaluation of the environment threats of accidents with transport of hazardous materials in the Amazon region.(author)

    Full Text Available OBJETIVO: Identificar a autopercepção da saúde bucal por adultos e variáveis associadas. MÉTODOS: Estudo realizado com os dados da Pesquisa Nacional de Saúde Bucal SBBrasil 2010 relativos a 2.456 adultos de 35 a 44 anos da região Nordeste. A variável dependente foi a autopercepção da saúde bucal. As variáveis independentes foram agrupadas em: demográficas, predisposição/facilitação, condição de saúde bucal e relacionadas à autopercepção da necessidade de tratamento. O teste de Rao e Scott foi utilizado para avaliar a associação entre essas variáveis. O efeito das variáveis independentes sobre o desfecho foi avaliado pelo modelo de regressão logística multinominal segundo modelo hierarquizado, em duas etapas: análise simples e análise múltipla hierarquizada. RESULTADOS: A autopercepção positiva da saúde bucal foi observada em 37% dos participantes. No modelo final, as características diretamente associadas a essa autopercepção foram: ser branco, ter renda familiar superior a R$ 500,00, possuir número de bens acima da mediana, ter maior número de dentes hígidos, não apresentar sangramento, não necessitar de prótese, Oral Impacts on Daily Performances = 0, não necessitar de tratamento e ter ido ao dentista há menos de três anos. CONCLUSÕES: Os resultados mostram que a autopercepção da saúde bucal dos adultos residentes no Nordeste brasileiro está diretamente associada a uma estrutura multidimensional de fatores. As baixas condições econômicas associadas às condições clínicas deficientes dessa população causam grande impacto na sua autopercepção da saúde bucal.

    Colorectal cancer (CRC) is the third most common malignant neoplasm worldwide and early diagnosis reduces morbidity. The standard preventive exams methods are uncomfortable for the patient, invasive, and /or are ionizing. Here, we evaluate the potential of magneto-motive ultrasound (MMUS) as a new, minimally invasive CRC screening technique. We developed a hybrid transducer (comprised of an ultrasound probe and a magnetic coil system) to construct relative elastography maps in a paraffin phantom with isoechoic inclusions. The electromagnetic component of our system manipulated ferromagnetic fluid located inside of our synthetic colon, and the captured ultrasound images were used to produce relative elastography maps. The MMUS images reveal by otherwise invisible structures based on differences in stiffness. Ultrasound elastography (relative) images by MMUs technique complements usual preventive CRC exams, is minimally invasive, has relative low cost when compared with others image methods. Also is fast diagnose and more comfortable for patient which prevents withdrawal of the screening. (author)

    Full Text Available The objective of this study was to obtain an estimate for residential electricity demand in Minas Gerais in the period from 1970 to 2002. Specifically, the goal was to estimate price and income elasticities. After determining that the series under study were non-stationary, we chose to use the Co-integration approach, estimating a Vector Error Correction Model (VEC Model. The results obtained show that the demand studied is more sensible to variations in the income than to the price of the electricity, although both elasticities are inferior to the unit. It was also concluded that price-elasticity is higher in Minas Gerais than it is for Brazil as a whole, suggesting differentiated usage of this energy among the different states in the Country.

    Full Text Available Posiblemente, el fenómeno urbanístico más sorprendente de los últimos 22 años, ha sido lo que se ha venido en llamar la “burbuja inmobiliaria”, el amplio ciclo inmobiliario expansivo que se desarrolla en España, entre 1995 y 2006, durante el cual se triplica el número de licencias de viviendas concedidas en España, que pasan de una media de 217.863 durante el quinquenio 1990-94 a las 737.186 que se alcanzan en 2006, una cifra más de tres veces superior a la anterior. La “burbuja inmobiliaria” o “tsunami urbanístico”, como también se ha llamado, ha dado lugar a una ingente cantidad de publicaciones, noticias y opiniones y ha sido un tema recurrente en la prensa española durante sus años finales y los primeros de la crisis que le siguió. Sin embargo, aparte de su mera dimensión cuantitativa global, en realidad, los rasgos del crecimiento urbano asociado a la publicitada y debatida “burbuja” son poco conocidos, mucho menos que la evolución de los precios y las ventas, que han centrado la atención pública, y una de las principales razones de este desconocimiento es seguramente la dificultad de contar con datos precisos de un fenómeno cuyo modelado y control es una competencia básicamente municipal, lo que significa que los datos detallados de este proceso están repartidos entre las 8.123 corporaciones municipales que, de acuerdo con el MINHA, componen España.

A legitimidade, destas conceções consolidam o poder capitalista e impulsionam o processo de urbanização.

MÉTODOS: Estudo transversal, de base populacional, conduzido de janeiro/2006 a junho/2007, na região metropolitana de São Paulo, como parte do estudo internacional (Gender, Alcohol, and Culture: an International Study. Os sujeitos (1.501, sendo 609 homens e 892 mulheres eram residentes da região metropolitana de São Paulo, tinham 30 anos ou mais de idade e foram selecionados aleatoriamente, a partir de amostragem complexa por conglomerados. Todos os indivíduos consentiram em participar da pesquisa. A variável dependente foi risco cardíaco avaliado através do WHO Rose Angina Questionnaire. A análise multivariada consistiu em regressão logística, tendo sido realizado ajuste para uso de tabaco e índice de massa corpórea. RESULTADOS: A taxa de resposta foi 75%. Ser mulher, ter mais idade, ser negro, fumante e ter um índice de massa corpórea elevado, foram associados a maior risco para doença coronariana. Indivíduos que nunca beberam na vida (OR = 2,22 e ex-bebedores (OR = 2,42 tiveram maior risco de doença cardíaca do que aqueles que informaram beber até 19 g de álcool por dia, sem episódios de beber excessivo. Entre os que tiveram episódios de embriaguês observou-se uma tendência a maior risco (OR = 3,95, p = 0,09. CONCLUSÕES: Nossos achados sugerem um menor risco para doença coronariana entre os bebedores moderados. Destaca-se que os estudos que avaliam o impacto do álcool sobre doença cardíaca precisam identificar o padrão de uso de álcool dos sujeitos, visto que este aspecto pode modificar o risco. Políticas públicas são necessárias para reduzir o uso nocivo de álcool e a morbidade a ele relacionada no país.

    In Brazil and particularly in the Northeast of Brazil, illuminance measures are not part of routine meteorological station measures, and therefore they are still rare than solar irradiation measures. In this context, two stations were installed in Pernambuco: one in Recife (maritime tropical climate) in April 2003 and the other in Pesqueira (tropical and semi-arid) in September 2004 for carrying out simultaneous measurements of hourly solar irradiation and illuminance which permit the modeling and the statistic validation of the relationship between these two parameters and with this, makes possible the estimation of illuminance where there existed only information on solar irradiation. The Alados et al. model with local coefficients showed a superior statistical performance, producing a mean bias deviation in the order of 3% and 1% and root mean quadratic deviation of 10% and 3% respectively for Recife and Pesqueira (author)

    The awareness of the importance of the environment has stimulated the study of new energy sources renewed and less pollutant. Amongst these sources, solar energy stands alone for being perennial and clean. The use of solar energy in systems of residential water heating, instead of the electric shower, can compliment the economy of electric energy, based on the Brazilian energy matrix. To know all the factors that influence the operation of a system of water heating by solar energy it is important the determination of its economic and technical viabilities and, distribution targeting in urban and agricultural residences. To evaluate equipment of water heating for solar energy in the region west of the Parana, Brazil, an archetype with similar characteristics to equipment used in residences for two inhabitants was built, to function with natural circulation or thermosyphon and without help of a complementary heating system. The room temperature and the speed of the wind were also evaluated, verifying its influence in the heating system. The equipment revealed technical viability, reaching the minimum temperature of 35 deg C for shower, whenever the solar radiation was above the 3500 W.m{sup -2}, for the majority of the studied days. The system operated without interruptions and it did not need maintenance, except for the monthly glass cleaning. Economic viability was clearly demonstrated since the useful life of the equipment exceeded the period of use to gain its investment. (author)

    The soybean is a vegetable with high nutritional value, mainly due to its high protein content. Among the culture of grains, the soy beam is the most important in Brazil, what represents a greater incentive for the consumption of this food. However, a great claim of occidental consumer is its characteristic odor and flavor, known as beany flavor, which is provided by the action of lipoxygenase enzyme. The catalytic action exerted by this type of isoenzyme on polyunsaturated fatty acids, linolenic and linoleic acid of the soy grains, is one of the main factors responsible for the appearance of the carbonyl compounds, which cause the unpleasant flavor in grains. To enhance the organoleptic characteristics of soybeans, researchers have developed new cultivars, without the presence of lipoxygenase. The objective of this study was to evaluate physical, chemical and sensorial differences between the two soy cultivar, with and without lipoxygenases (cultivars BRS 232 and BRS 257, of EMBRAPA, respectively) and to analyze the possible changes promoted by different radiation doses (0, 4 and 8 kGy) in raw and cooked soybean grains. The physical analyses were: time of cooking and hydration of the grains. The chemical analyses were: centesimal composition, protein digestibility, anti nutritional factors, isoflavone content and antioxidant capacity (DPPH and ABTS). The sensory aspects were determined by sensorial analysis performed by applying analytical methods of differentiation for selection of panelists, and descriptive method to determine the quality of the soybean. At the end, factorial statistical analysis was performed 3x2x2 (irradiation doses X cultivars x treatment) for analysis, comparison and discussion of the obtained results. The results showed differences in physical analyses with the irradiation and between the two cultivars. Besides, the cultivars presented differences in the centesimal composition, digestibility fenolic content, isoflavone content and trypsin inhibitor. Cooking promoted difference in all the studied components, except for the proteic digestibility of the grains. On the other hand, the irradiation affected the anti nutritional contents, the proteic digestibility and the content of aglicone isoflavones. Data from sensory analysis showed that the taste and the texture of the samples didn't differ between the cultivars and were not affected by the irradiation. (author)

    The interest on questions related to environmental conservation has increased in recent decades, being air pollution one of the main public health problems in huge urban centers. Major part of this atmospheric contamination is caused by gaseous pollutants and inhalable particulate matter. One of the main sources is the burning of fossil fuels mainly emitted by motor vehicles. Some organisms, like lichen and atmospheric bromeliad, are able to accumulate chemical elements in their tissues, thereby becoming excellent tools for air quality studies of monitoring. The present work evaluated the air quality in the Metropolitan Region of Recife (RMR) using the lichen Cladonia verticillaris and the bromeliad Tillandsia recurvata, through the quantification of chemical elements associated to vehicles traffic. The biomonitors were transferred to 40 points distributed in the RMR with different intensities of the vehicle traffic. After the exposition period of six months, Al, Ba, Ca, Cd, Cl, Fe, Mg, Mn, P, Pb, Sb, Sr, Th, V and Zn were quantified by Energy Dispersive X-Ray Fluorescence (EDXRF) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The organisms were complementary, being appropriated tools for monitoring the air quality. The vehicle traffic was considered one of the major contributor for increasing chemical elements in the RMR urban atmosphere. (author)

    Natural gas has become one of the most important energy sources, as we can observe in most countries' energy sector, where its presence is very significant. In Brazil, natural gas corresponds to 7,5% of all energy Also available, and the government has plans to increase this number to 12% until 2010. However, in order to reach this goal, it is important to understand how market works, evaluating all the aspects that have some influence on it. This paper goal is to analyze the natural gas market in Fortaleza metropolitan region, emphasizing the industrial sector, the biggest consumer in Ceara State. The main aspects are characterized here, like professionals qualification in the area, service quality, from equipment and maintenance suppliers until gas distributors, legal aspects, and other factors that are also relevant to a possible future expansion of different natural gas market segments (industry, residence, commerce and transport).

    Due to the increasing problems of atmospheric pollution in the Sao Paulo metropolitan region that affect the environment and human health the application of biomonitoring methodologies using cosmopolite organisms has now become relevant. Biomonitoring is a method to evaluate the response of live organisms to pollution. This method offers advantages such as reduced costs, efficient monitoring of large geographic areas and accumulated pollutants over a large period in which low concentrations of chemicals elements in the environment can be evaluated. In the present study, neutron activation analysis method was applied to determine elements accumulated in Canoparmelia texana lichenized fungi. Samples were collected in two distinct areas: Carlos Botelho (PECB) and Intervales (PEI) State Parks that are considered as non-polluted areas and that belong to the Atlantic Forest - SP ecosystem; and Sao Paulo city metropolitan region in sites near automatic monitoring stations of the Environmental Protection Agency of the State of Sao Paulo (CETESB). The lichens collected from the bark of the trees were properly treated, and irradiated with neutrons from IEA-R1 nuclear reactor along with synthetic standards of elements. The precision and the accuracy of the results were evaluated by the analyses of IAEA-336 LICHEN and Mixed Polish Herbs (INCT -MPH-2) certified reference materials. The results obtained for these materials were in accordance with the certified values and presented good precision with variation coefficients ranging from 0.9 to 14.6%. Results obtained for lichens showed that elements As, Co, Cr, Cs, La, Mo, Sb, Sc, Se and U are present at ng g{sup -1} levels, Ba, Br, Cl, Fe, K, Mn, Na, Rb and Zn at {mu}g g{sup -1} and Ca at mg g{sup -1}. By applying cluster and discriminant analyses to the results for the lichen samples from areas with different levels of pollution, the sampling sites were grouped according to their chemical similarities and their elemental composition. It was also observed that samples from PECB and PEI were separated from groups and subgroups formed by the samples from the metropolitan region. This result indicates the preservation of PECB and PEI areas considered non-polluted. The lichens collected in the PEI presented, in general, lower concentrations of the elements than those from the metropolitan region of Sao Paulo in regards to those elements related to anthropogenic actions. The distribution maps of element concentrations allowed identification of sites in the metropolitan region that present higher elemental concentrations. Furthermore the distribution maps also showed that the pollution in the metropolitan region presents different profiles due to many sources and different pollutant emissions. The probable sources of elements determined in lichens from the metropolitan region are industrial, vehicular and soil. Results obtained indicate that the C. texana species can be used as a passive biomonitor of element pollution in the Sao Paulo metropolitan area. This species is abundant in both polluted and non-polluted areas and thus allows to distinguish regions with distinct levels of pollution. (author)

    The present work was developed in outcrops of Santa Maria region, southern Brazil, Rio Grande do Sul State. Statistic evaluations were applied in different rock types. The possibility to distinguish different geologic units, sedimentary and volcanic (acid and basic types) by means of the statistic analyses from the use of airborne gamma-ray spectrometry integrating potash radiation emissions data with geological and geochemistry data is discussed. This Project was carried out at 1973 by Geological Survey of Brazil/Companhia de Pesquisas de Recursos Minerais. The Camaqua Project evaluated the behavior of potash concentrations generating XYZ Geosof 1997 format, one grid, thematic map and digital thematic map files from this total area. Using these data base, the integration of statistics analyses in sedimentary formations which belong to the Depressao Central do Rio Grande do Sul and/or to volcanic rocks from Planalto da Serra Geral at the border of Parana Basin was tested. Univariate statistics model was used: the media, the standard media error, and the trust limits were estimated. The Tukey's Test was used in order to compare mean values. The results allowed to create criteria to distinguish geological formations based on their potash content. The back-calibration technique was employed to transform K radiation to percentage. Inside this context it was possible to define characteristic values from radioactive potash emissions and their trust ranges in relation to geologic formations. The potash variable when evaluated in relation to geographic Universal Transverse Mercator coordinates system showed a spatial relation following one polynomial model of second order, with one determination coefficient. The statistica 7.1 software Generalist Linear Models produced by Statistics Department of Federal University of Santa Maria/Brazil was used. (author)

    This paper presents the basic concepts of radiation protection to guide the health care professionals who use equipment emitting ionizing radiation on the correct handling of the beams of radiation. Radiometric evaluations were conducted in 1665 in X-ray equipment, installed in dental surgeries and clinics, hospitals and radiology services, during the years 1996 to 2003 in the region of Aracatuba. Tests of radiometry are presented as a technical report where the parameters are quantified physical and radiological verifying its compliance with the established by legislation. The distribution of reports by type of unit shows that the vast majority of equipment is of periapical dental x-rays (72%), 25% of equipment is medical equipment for radiology and 3% is dental equipment panoramic model (orthodontic documentation). Among the physical parameters analyzed, the length of the browser was showing more variance compared to the required by law, this fact may also contribute to gaps in the rate of the radiation dose and the size of field in the skin of the patient, the that can easily be resolved simply to replace the piece at the outlet of the head. During the completion of visits to services, it also noted a gap in the training of professionals who operate this equipment emitting radiation, warning of the need for specific training in the area.

    Clay materials crop out in the northern Santa Catarina mining district were investigated in order to assess their potential in the ceramic industry. Four different clays (A, B, C and D) were selected. Their chemical composition was obtained by Xray fluorescence and their mineralogy by X-ray diffraction, coupled with numerical rational analysis. Their thermal behaviour was studied by differential thermal analysis. Technological testing consisted in a simulation of the industrial processing performed at a laboratory scale. The test pieces were obtained by pressing and fired in the range of 850-1200 deg C. In each case their technological properties were studied. The main mineralogical phases detected were kaolinite, quartz and mica. Hematite and feldspars may be present in the clays. The clays show two groups of particle sizes almost equally frequent in the range of 1 to 60 {mu}m. The northern Santa Catarina clays are suitable for the production of bricks and earthenware in the 900- 1100 deg C range. (author)

    Seismic multichannel, gravity and magnetometry measurements were carried out in the region of West coast of the Antarctic Peninsula, Bransfield Strait, South Shetland Islands and South Shetland Trench, by Brazilian Antarctic Program during the summers of 1987 and 1988. The present work, using a continue seismic and gravity and gravity data profile crossing the area, intends to present a two-dimensional model of the crust thickness in this region. By this model, the Moho discontinuity would lie at a depth of 14.5 km below the axis of the Bransfield trough. This anomalous behaviour in addition to compressional processes identified in the accretionary prism and trench, was interpreted as an evidence of the continued opening of the Bransfield basin.

    Bring energy to isolated communities is not easy. Among the possibilities there are the sizes of small wind systems. Within the government policy to serve the isolated communities and maroon many alternatives are being tested. The use of wind power in places where there is availability of wind is a very attractive alternative. This paper presents a small central generation of hydropower and solar wind, installed in the Boa Esperanca community, with maximum capacity to generate 3kW. The system consists of three turbines of domestic manufacturing, which generate at 48 V. The energy is used in the 'Community Workshop'. The energy in the workshop is available in 220V. The partial results show that the system can be technically and economically viable, or sustainable, provided there is the involvement of the community as a whole in the proper use of energy, maintenance and operation of micro-central generation.

    This paper presents the results of a technical and economical feasibility study for the use of micro cogeneration systems in residential scale, using natural gas as an energy source. It was considered two micro-cogeneration systems to meet demand of some types of fictitious establishment of commercial and residential plants, each with its advantages and disadvantages. The first system has as a main driving machine a micro turbine with a nominal capacity of 30 kw, the second one uses a gas motor-generator, with nominal capacity of 35 kw. (author)

    Full Text Available En la ciudad de México, al igual que en las metrópolis modernas de América Latina, grandes mayorías de la población no logran acceder a los ingresos, los recursos y las oportunidades que garanticen condiciones de trabajo y de vida dignas. La pobreza, la desigualdad y diferentes formas de exclusión social afectan la cohesión social. Los diferentes métodos para estimar la magnitud y características de la pobreza permiten conocer la escala y características que adquiere esta problemática. De esta forma entre los bienes y servicios que ofrece la ciudad a quienes en ella habitan se analizan las acciones públicas emprendidas para mejorar o construir nuevos espacios públicos, para promover prácticas colectivas - deportivas, culturales y recreativas - que contribuyan a fortalecer la identidad local y la vida comunitaria. Interesa recuperar particularmente la experiencia del Programa Comunitario de Mejoramiento Barrial, impulsado por el gobierno del Distrito Federal desde el año 2007, el cual constituye una masiva e innovadora acción participativa que ha logrado transformar un amplio número de espacios públicos en barrios colonias y pueblos que se encuentran en condiciones de marginación urbana y degradación social. En este artículo se analizan dos casos exitosos de transformación de espacios públicos con recursos del Programa lo cual ha contribuido a la promoción de la participación ciudadana. La metodología utilizada en este trabajo es cualitativa y se sustenta en la recopilación y sistematización de fuentes documentales, entrevistas a actores institucionales y sociales y la observación participante de los autores en los casos de estudio seleccionados.In Mexico City, as well as in other Latin American modern metropolises, huge majorities among population do not get access to income, resources and opportunities that may guarantee adequate conditions living and labor conditions. Poverty, inequality and distinct ways of social exclusion affect social cohesion. The distinct methods used to assess the extent and characteristics of poverty allow for understanding the range and features assumed by this problem. Therefore, among the goods and services offered by the city to those who live in it, this study analyses the public actions taken with the purpose of improving or building new public spaces aimed at promoting collective practices - sports, cultural and recreational areas - which may contribute to strengthen both local identity and community life. It is aimed, particularly, at retrieving the experience of Programa Comunitario de Mejoramiento Barrial (Community Program for Neighborhood Improvement, an initiative of the Federal District government, in force since 2007, that constitutes a massive and innovative participatory action which succeeded in transforming a large number of public spaces in neighborhoods, districts and shantytowns that were under conditions of urban marginalization and social degradation. This article presents two successful cases, in which the governmental support program led to changes in public spaces that contributed for promoting community participation.

    Full Text Available O trabalho tem por objetivo apresentar os usos finais de eletricidade e rotinas de uso em habitações de interesse social. Os dados foram obtidos por meio de auditoria energética em uma amostra de 60 habitações de interesse social da região de Florianópolis-SC, por meio de aplicação de questionários aos moradores e medições do consumo de energia elétrica. Os dados obtidos com os questionários se referem à situação socioeconômica dos moradores e às rotinas de uso dos equipamentos eletroeletrônicos e iluminação, estimados para períodos de verão e inverno. As medições foram utilizadas para a caracterização dos equipamentos e lâmpadas, determinação do consumo de energia elétrica e o tempo de uso, por um período maior do que duas semanas em cada habitação. O tratamento de dados foi feito em forma de intervalos de confiança, por meio de métodos estatísticos paramétricos e não paramétricos. Os resultados mostraram que o chuveiro elétrico representa o maior uso final da amostra, com 36,8% de mediana, seguido dos refrigeradores, televisão e iluminação. Os dados não mostraram diferenças significativas entre os períodos de verão e inverno, devido ao tamanho reduzido da amostra e à variabilidade dos dados. As rotinas de uso encontradas, quando associadas à densidade potência média respectiva, são variáveis de entrada para estudos de simulação computacional do desempenho térmico dessas habitações, além de ajudarem na caracterização desse tipo de edificação. A correta quantificação dos usos finais de eletricidade de amostras pequenas leva à adoção de medidas corretas e específicas para a eficiência energética dessas habitações.

    Full Text Available In the last 20 years, the phenomena generally classified in terms of “personal insecurity” or “urban violence” have yielded significant changes in the metropolitan variables and in the social relations conforming or not the inhabitants as citizens and civics in Caracas. By assessing the installation, proliferation and normalization of security devices established by civil neighbor associations in order to protect urbanizations of middle and high class sectors, and legitimized by the acts or omissions of several government and non government institutions, it is possible to measure, according to the principles of pragmatic sociology, how in Caracas contemporary forms of segregation and of residential homogenization are crystallized between watchful sociability and exclusive urbanity

    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”.

    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.

    2004-01-01

    Full Text Available One of the basic points of the social policy of the Spanish Crown in America and specifically in the Kingdom of Nueva Granada was the dualism or división between the community or Republic of the Spaniards and the Republic of the Indians. The term «human» changed from meaning «living collectively» to «toll of the bell» or «in pólice» in «republic». This was made concrete in two inter-related dimensions: on the one hand, in the design of a certain type of stratified urban spatial configuration and, on the other hand, in the promotion of a type of subject who would respond to said conditions of «coexistence», and the condemnation of those who did not enroll in the «well-ordered» way of life. Thus, the policies aimed at reducing the indian population, originally differentiated from the urban population, which was considered to be the space of «civilization», «whites», and «other people», were logically reinforced through mechanisms such as residential segregation policies. Nevertheless, this ideal visión of socio- spatial order would confront in practice, on the one hand, the Spaniards' need to have the indians cióse at hand for various reasons, especially of an economic nature and, on the other hand, the danger of disturbances resulting from crossbreeding between the white and indian races.

    Full Text Available Las metrópolis de América Latina muestran un interés creciente para la imple-mentación de políticas urbanas de redensificación en sus áreas centrales, espacios que sufren pérdidas de población muy importantes desde hace varias décadas. Sin embargo, antes de implementar medidas para retener a los residentes actuales y atraer a nuevos, resulta indispensable no limitarse a la mera evidencia de una disminución del número de residentes: se tiene que establecer un diagnóstico a profundidad referente al proceso de despoblamiento. Dentro de este diagnóstico, resulta necesario analizar los movimientos migratorios hacia y a partir del centro, con el objetivo de conocer, entre otras variables, cuáles son los perfiles de los habitantes que abandonan el centro y hacia dónde se dirigen. Es solo a partir de estas variables que se podrán diseñar políticas urbanas adecuadas. Además, tal y como lo muestra el caso aquí estudiado de la Ciudad de México, es sumamente importante desarrollar estrategias urbanas globales para toda la metrópoli.Latin American metrópoli reveal an increasing interest in urban policies of redensification of central area which have suffered population loss over several decades. However, prior implementing measures to retain existing residents and attract new ones, it is necessary not to be restricted to mere evidence of a reduction of the number of residents: a more profound diagnosis of the population loss process is required. Within this diagnosis, it is necessary to analyze migratory patterns to and from the centre, with the aim of revealing, among other variables, the profiles of the inhabitants who leave the centre, and where they move. It is only from these variables that it is possible to design adequate urban policies. Also, as the Mexico City case illustrates, it is very important to develop global urban strategies for the whole of the metropolis.

    Full Text Available Los censos de la ronda de 2000 de Brasil, México y Chile incluyeron, por primera vez, una consulta sobre lugar de trabajo o estudio. Su procesamiento generó resultados novedosos sobre la segmentación socioeconómica de la movilidad diaria en Rio de Janeiro, Sao Paulo, Santiago y Ciudad de México. En estas dos últimas-donde el censo captura mejor la movilidad diaria-, hay un contrapunto entre la situación individual y la geográfica, porque la probabilidad de trabajar en una comuna distinta a la de residencia aumenta con el nivel socioeconómico de las personas, pero los municipios pobres tienden a tener índices de salida de trabajadores superiores. Esto último se explica por la concentración de los empleos en el centro comercial y en el habitat de la élite, normalmente distantes de los municipios pobres, sobre todo en ciudades altamente segregadas. Este hallazgo ensombrece la hipótesis de un futuro policéntrico para las metrópolis latinoamericanas.For the first time in history, the 2000 round of censuses in Brazil, Mexico and Chile asked citizens a question about the location of their places of work or study. Analysis of census data produced new results on how daily commutes in Rio de Janeiro, Sao Paulo, Santiago and Mexico City vary across socioeconomic groups. In Santiago and Mexico City, where the census question better captures daily commutes, there is an interesting paradox regarding individuals economic status and their geographic location because the likelihood that one's workplace is located in a different municipality from their residence increases as their socioeconomic status rises. However, the poorest municipalities tend to have higher indices of daily commuting This is due to the concentration of employment in the Central Business Districts and wealthy areas, which are usually located far from the poorest municipalities, especially in highly segregated cities. This finding challenges the hypothesis that the Latin American cities of the future will be polycentric.

    Full Text Available En este artículo se analiza la relación entre los cambios en la distribución espacial de la población y la producción de edificios residenciales verticales en los distritos de São Paulo. Para desarrollar este análisis, utilizamos los datos del censo de 1991, 2000 y 2010 articulados con datos sobre la producción de edificios nuevos de apartamentos colocados a la venta durante el período entre 1998 y 2008. Estas bases de datos fueron utilizadas para el desarrollo de una metodología que permitió la construcción de la Tasa de Absorción de la Población por la Producción de Apartamentos (TAPPA. El TAPPA intenta estimar cuánto del Crecimiento de la Población (CP en los distritos de São Paulo ocurrido entre 2000 y 2010 fue absorbido en los apartamentos colocados a la venta entre 1998 y 2008 por agentes del mercado inmobiliario. Para calcular la TAPPA se calculó el Crecimiento de la Población Potencial que há sido Absorbida por la Producción de Apartamentos (CPPAPA, calculado en base al número de residentes por apartamento extraído del Censo de 2010. Se concluyó que, de hecho, el segmento de la producción de edificios de apartamentos condiciona en gran medida a la distribución espacial de la población de São Paulo en los distritos centrales que tenían una inversión demográfica de perdida para aumentos de población en la transición de los años 1990 a 2000. No se notó el mismo fenómeno en las periferias de la ciudad.

Es necesario clarificar: ¿qué se evalúa, qué se quiere medir?, ¿cómo se evalúa?, ¿por qué se evalúa? Se evalúan las condiciones de habitabilidad de los alojamientos y la satisfacción de su población, de acuerdo a los lineamientos planteados por el programa de Hábitat II. La metodología propuesta es síntesis de métodos cuanticualitativos que intentan conciliar la noción de éxito de las instituciones gubernamentales con la de los usuarios, superar los escollos de particularidades para posibilitar la replicabilidad sin perder información, y clarificar un criterio de ponderación que asegure una valoración que no arroje resultados distorsionados. Y finalmente, se evalúa con el propósito de influir en la dirección de las políticas habitacionales, en la búsqueda de argumentos racionales en las tomas de decisiones.

    Full Text Available OBJECTIVE: Analyse how basic sanitation conditions, water supply and housing conditions affect the concentration of Culex quinquefasciatus METHODS: Populations of C. quinquefasciatus in 61 houses in the municipality of Olinda, PE, were monitored between October 2009 and October 2010. Observations were carried out in homes without the presence of preferred breeding sites in order to identify characteristics that may be aggravating factors for the development of the mosquito. Five aggravating factors were analysed: vegetation cover surrounding the home, number of residents/home, water storage, sewage drainage and water drainage. These characteristics were analysed in terms of presence or absence and as indicators of the degree of infestation, which was estimated through monitoring the concentration of eggs (oviposition traps - BR-OVT and adults (CDC light traps. RESULTS: Sewage drainage to a rudimentary septic tank or to the open air was the most frequent aggravating factor in the homes (91.8%, although the presence of vegetation was the only characteristic that significantly influenced the increase in the number of egg rafts (p = 0.02. The BR-OVT achieved positive results in 95.1% of the evaluations, with the presence of at least one egg raft per month. A total of 2,366 adults were caught, with a mosquito/room/night ratio of 32.9. No significant difference was found in the number of mosquitoes caught in the homes. CONCLUSIONS: Although the sanitation and water supply influence the population density of C. quinquefasciatus, residence features that are not usually considered in control measures can be aggravating factors in sustaining the mosquito population.OBJETIVO: Analizar como las condiciones de saneamiento básico, abastecimiento de agua y habitaciones afectan la densidad de Culex quinquefasciatus MÉTODOS: se monitoreó la población de C. quinquefasciatus en 61 residencias del municipio de Olinda, PE, Brasil, de octubre de 2009 a octubre de 2010. Las observaciones se realizaron en residencias sin la presencia de criaderos preferenciales, para identificar características que pueden contribuir como agravantes para el desarrollo del mosquito. Cinco características agravantes fueron analizadas: cobertura vegetal en el peridomicilio, número de habitantes por residencia, almacenamiento de agua, drenaje de cloacas, drenaje de agua. Se evaluó la presencia o ausencia de estas características y como indicadores de niveles de infestación, estimados por monitoreo de la densidad de huevos (trampas de oviposición BR-OVT y adultos (trampas luminosas de tipo CDC. RESULTADOS: El drenaje de cloacas hacia el pozo séptico/rudimentario y hacia el ambiente fue lo más frecuente en las residencias (91,8%, a pesar de que sólo la presencia de vegetación haya influenciado significativamente en el aumento de las "balsas" (p=0,02. Las BR-OVT se presentaron positivas en 95,1% de las evaluaciones, con presencia de por lo menos una balsa/mes. Se capturaron 2.366 especímenes adultos, con relación mosquito/cuarto/noche de 32,9, sin diferencia significativa en el número de mosquitos capturados en las residencias. CONCLUSIONES: A pesar de que las condiciones de saneamiento y de abastecimiento de agua influencien en la densidad poblacional de C. quinquefasciatus, características de la residencia que normalmente no son consideradas en las medidas de control pueden ser factores agravantes en el mantenimiento de la población de mosquito.OBJETIVO: Analisar como as condições de saneamento básico, abastecimento de água e habitações afetam a densidade de Culex quinquefasciatus.

Essas características foram avaliadas quanto à presença ou ausência e como indicadores de níveis de infestação, estimados por monitoramento da densidade de ovos (armadilhas de oviposição BR-OVT e adultos (armadilhas luminosas do tipo CDC. RESULTADOS: O escoamento de esgoto para fossa séptica/rudimentar e a céu aberto foi o mais frequente nas residências (91,8%, embora apenas a presença de vegetação tenha influenciado significativamente no aumento de jangadas (p = 0,02. As BR-OVT apresentaram-se positivas em 95,1% das avaliações, com presença de pelo menos uma jangada/mês. Foram capturados 2.366 espécimes adultos, com relação mosquito/quarto/noite de 32,9, sem diferença significativa no número de mosquitos capturados nas residências. CONCLUSÕES: Embora as condições de saneamento e de abastecimento de água influenciem na densidade populacional de C. quinquefasciatus, características da residência que normalmente não são consideradas nas medidas de controle podem ser fatores agravantes na manutenção da população de mosquito.

    The analysis of petrographic, geochemical and geochronological data of granites in the Peixoto de Azevedo region, Mato Grosso, Brazil, in the eastern portion of the Alta Floresta Gold Province, led to the recognition of two granitic bodies bounded by regional major faults and shear zones. In the northwestern portion a body with featured as biotite granodiorite, coarse-grained, with porphyritic to inequigranular texture, metaluminous to peraluminous, high-K calc-alkaline and magnesium character. In the southeastern portion of the area, a biotite monzogranite coarse-grained, with equigranular to porphyritic texture, slightly peraluminous, high-K calc-alkaline and dominantly of ferrous character. U- Pb dating (SHRIMP) showed that the biotite monzogranite has an age of 1869 ± 10 Ma, similar to the Matupa Intrusive Suite, while the biotite granodiorite has an age of 1781 ± 10 Ma, that is the age expected to Peixoto Granite. Both units show patterns of rare earth elements with enrichment of light over heavy and negative Eu anomaly (La{sub N}/Yb{sub N} » 7.6 to 17.31 and ratios Eu/EU{sup ⁎} between 0.46 – 0.72 for biotite monzogranite and La{sub N}/Yb{sub N} » 7.13 to 29.09 with ratios Eu/Eu{sup ⁎} between 0.25 - 0.40 for the biotite granodiorite). Trace elements pattern for both present negative anomalies of Ba, P, Ti and Nb indicating an evolution from mineral fractionation and subduction related sources. In this paper, it is suggested that the monzogranite Matupa was developed in mature arc tectonic environment. For the Peixoto Granite, two hypotheses are suggested: (a) it was developed in younger magmatic arc environment associated with the Colider Magmatism or (b) it was generated in extensional tectonic environment during the Columbia Super continent break up.

    A gamma spectrometry profile was carried out along BR174 highway, that crosses some lithostratigraphic units of the North portion of the Sedimentary Basin of Amazon. Measurements in situ were realized in 116 points, 1 km apart, using a GAD-6 gamma-spectrometer and samples of rocks and soils were collected in geologically representative points, for gamma measurements using a shielded detector of NaI(Tl) available in the Nuclear Geophysics Laboratory of IAG/USP. The criterion used for evaluating the reliability degree of the concentration values of eU (ppm), eTh (ppm) and %K was to establish mathematically detection limits, for all measurement points. Every these points had been located using GPS with accuracy of 50 m to become possible a future detailed study. The purpose of matching portable gamma spectrometer and laboratory determinations was to compare the 2 techniques, using the criterion of detectability limits, and to verify the influence of {sup 222} Rn atmospheric radioactive gas in field measurements. In the case of portable detector, it allows fast measurements and the sensor 'sees' a big volume of material (rock, soil...), that makes it more representative. In some situations where atmospheric phenomena of thermal inversion occurs, measurement can be affected by the {sup 222} Rn cosmic background. Presence of radon daughter elements, associated with aerosols, in this tropical environment (high values of temperature and humidity), where the speed of the wind that could exhaust this gas is practically zero. It is observed that the values of concentration in the some points, got with these 2 techniques, have the same trend, and the stretches where peaks of concentration of K also occur and U and Th are associated with the presence of granite out corps, great boulders, and clay soils from weathering of these rocks.

    This research objective was to assess the level of randon-222 concentration in well water of the metropolitan region of Curitiba, Parana. Current work presents the results of indoor {sup 222}Rn activity ground water samples from artesian wells from aquifers of the region. The studies of radon activity in water were performed using the radon detector AlphaGUARD. The calculations of initial radon activity in water were done considering the {sup 222}Rn decay correction as well as equilibrium level of {sup 222}Rn and {sup 226}Ra observed after 30 days of measurements. Obtained results show that about 70% of measured activity levels of {sup 222}Rn are higher than the recommended value of 11.1 Bq.L{sup -1}, which represent the risk for the human health associated with this radionuclide. The case study showed that previous measurements of radon are recommended for a construction project is implemented. In this case, it is observed that the radon concentrations decrease about 56% in the first water tank and 83% in the second water tank over the well. This fact shows that the actions for mitigation of radon are viable and do not require major modifications to the usual systems of construction. (author)

    This work deals with the measurement of radioactive lines in powdered milk, with high resolution gamma spectrometry, using a HPGe detector with relative efficiency of 10%, coupled to the electronic nuclear chain and a multichannel card of 8192 channels. Some tests were realized before beginning the measurements. The first of them was to define the shield to be used, making several measured with different shields according to the available materials, opting finally for a shield composed of bricks of lead (10 cm thickness), plates of iron (4nm thickness) and of aluminum (2 mm thickness). Four different geometries for the samples recipients were tested, and the Marinelli beaker of 2,1 liters totally filled was the one which supplied the best peak/background ratio. A statistical inference was also realized to determine the sampling that represents each one of the lots of milk to be measured, resulting in a number of 6 samples, for a confidence level of 95%. Two different kinds of powdered milk produced at Londrina were analyzed, Integral Powdered Milk Cativa and Integral Powdered Milk Polly. The samples were properly put in the Marinelli beaker of 2,1 L, sealed and kept for 40 days to reach the secular equilibrium. The counting time for each measurement was two days. It was possible to identify the radionuclides {sup 40} K, {sup 137} Cs and {sup 232} Th (from {sup 208} Tl), whose activities were calculated according to the International Atomic Energy Agency norms (IAEA, 1989). The detector efficiency was measured using calibrated samples, prepared with the certified reference materials IAEA-326 and IAEA-375. Corrections for self-absorption were accomplished, based on measures of samples with different densities. The results obtained for the powdered milk Cativa were: 464{+-} 12 Bq/kg for {sup 40} K, 3,46 {sup {+-}} 1,05 and 0,46 {+-} 1,05 and 0,46 {+-} 0,16 Bq/kg for the minimum detectable activities of {sup 137} Cs and {sup 232} Th, respectively. For the milk Polly, the results were: 452{+-}10 Bq/kg for {sup 40} K, 3,19{sup {+-}} 0,63 and 0,32{sup {+-}} 0,12 Bq/kg for the minimum detectable activities of {sup 137} Cs and {sup 232} Th, respectively. The statistical analyses performed checked the measurements repeatability by means of the Tukey's average comparison test. A correlation analysis between standard deviations and the mean showed the absence of significant systematic deviation. Comparison the results obtained with literature, it was demonstrated that the values of the activities found are within the normal levels of radioactivity for this kind of product and below the maximum permissible levels established by CNEN, that is, the analyzed milk can be normally consumed. On the other hand, the implemented methodology present a good performance, faced to the available experimental conditions. (author)

    A comparative analysis was made in this work among Pasquill-Gifford (PG) atmospheric dispersion coefficients and those determined at the Juelich and Karlsruhe sites with the purpose of suggesting which one would be the most applicable to the Angra site. Each one of the three systems was determined by different experiments, carried out over sites with diversified features. The systems of Juelich and Karlsruhe were obtained over sites with high surface roughness and from stacks (elevated releases), while the PG system was obtained over sites with a small surface roughness and from ground level releases. The results of the application of these systems at a complex site like Angra,which has a highly diversified structure encompassing sea, vegetation, predominance of light winds and stable stability classes, show that the PG system, the most used in the world, is still the best choice.

    This work presents the preliminary results about the concentration of radon and radon daughters in wells and springs water from Presidente Prudente. Six water samples were studied: three from well-water, two from springs water and one from potable water. For the determination of α-activity the samples were placed inside plastic containers where the CR-39 tracks detectors were outside the water. The track density of α-particles were measured by using optical microscopy. The results show that one sample from well-water presented higher concentration of radon and radon daughters than the other samples. (author)

    Among the reforesting companies holding a partnership program on eucalyptus plantations with small and medium farmers in Minas Gerais, the Pains Florestal S.A. stands out for creating a research and development program in agroforestry systems with eucalyptus. Following a successful biological research, the need for a more specific diagnosis of the social-economic conditions emerged in order to assess the viability of the program. It was found that the company's partners lack important financial resources to start new agricultural and forest enterprises in their lands. Additionally, their technological level was low. The main income sources are livestock, corn plantations and charcoal production. On the other hand, most farmers presented a high level of interest in beginning new activities, provided credit conditions were available. (author)

    The measurement of the Nat Pt photofission yield at 69 MeV of effective average energy of the incident photon is made using a polarized and monochromatic photon beam from the LADON system of the National Laboratory of Frascati, Italy, produced by inverse Compton scattering of laser light by high energy electrons of the ADONE Accelerator and using as fission track solid detector the Makrofol, being the developing made by usual procedure. The experimental value of the nuclear fissionability is compared to a theoretical value obtained following a model at two stages: in the first, the photon energy is absorbed by a neutron-proton pair inducing to the nucleus excitation, and in the second the nucleus de-excites due to the competition between nucleon evaporation and fission. The effect of fast nucleon emission during the first stage and the successive evaporation of neutrons in the second stage are considered. 40 refs, 12 figs, 9 tabs.

    This work describes the study using mechanical tests with the blend of recycled poly(ethylene terephthalate) (PET) and recycled polyolefin with and without the addition of polypropylene grafted with maleic anhydride and poly(ethylene-co-octene-1). A thermodynamic approach based on the Helmholtz work function was applied in the analysis of mechanical tests, correlating the effects of energy storage and from the compatibilizer on the elastic region of the materials. For the system studied, the polyolefin-rich region shows higher storage of elastic energy corroborating the morphology images obtained from SEM analysis. The thermodynamic analysis seems a useful tool to evaluate the compatibilizer effect in polymeric immiscible blends. In this work, more specifically, this method was used to analyze the mechanical behavior of different compositions of recycled polymeric commodity materials. (author)

    The wind behavior of a region can be described by frequency distribution that provide information and characteristics needed for a possible deployment of wind energy harvesting in the region. These characteristics, such as the annual average speed, the variance and shunting line standard of the registered speeds and the density of aeolian power average hourly, can be gotten by the frequency of occurrence of determined speed, that in turn must be studied through analytical expressions. The more adjusted analytical function for aeolian distributions is the function of density of Weibull, that can be determined by numerical methods and linear regressions. Once you have determined this function, all wind characteristics mentioned above may be determined accurately. The objective of this work is to characterize the aeolian behavior in the region of Botucatu-SP and to determine the energy potential for implementation of aeolian turbines. For the development of the present research, was used an Monitorial Young Wind anemometer of Campbell company installed a 10 meters of height. The experiment was developed in the Nucleus of Alternative Energies and Renewed - NEAR of the Laboratory of Agricultural Energize of the Department of Agricultural Engineering of the UNESP, Agronomy Sciences Faculty, Lageado Experimental Farm, located in the city of Botucatu - SP. The geographic localization is defined by the coordinates 22 deg 51' South latitude (S) and 48 deg 26' Longitude West (W) and average altitude of 786 meters above sea level. The analysis was carried through using registers of speed of the wind during the period of September of 2004 the September of 2005. After determined the distribution of frequencies of the hourly average speed of the wind, it was determined function of associated Weibull, thus making possible the determination of the annual average speed of the wind (2,77 m/s), of the shunting line standard of the registered speeds (0,55 m/s), of the coefficient of variation (20%) and of the density of aeolian power average hourly (24,58 W/m{sup 2}).

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr{sup 87} / Sr{sup 86} initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle 201 refs., 130 figs., 6 tabs., 2 maps

    The archaeological site of Caninhas is made of funeral and combustion structures and various objects of aboriginal daily use. These parts and fragments were safe and inventoried, constituting approximately 4000 units. The objective of this project was to analyze the microstructure and composition of archaeological ceramics, and ceramics made of argil current of the zone. The crystalline phases were identified by X-Rays Diffraction (XRD), elementary composition was obtained by X-Rays Fluorescence (XRF) and Energy Dispersive Spectrometry (EDS), and the microstructure was evaluated by Scanning Electron Microscope (SEM). Composition and microstructure of archaeological ceramics are different of current ceramics, indicating the effect of lixiviation in function of the time and the microstructural evolution due different ceramic processing. These results are valuable for the archaeological area studies, mainly for the cultural denoting which represents. The relation between some studies is basic to add knowledge: use of the ceramic materials engineering for archaeology application. (author)

    The Taciba and Rio Bonito ('lower' Triunfo Mbr) formations are divided into six depositional sequences based on cores, gamma-ray and electrical logs from shallow drillings from northern Santa Catarina State, Brazil. Each sequence is formed by two systems tracts, a lower one, sandy (low stand) and an upper one, shaly (high stand). The Taciba Formation has three sequences, S{sub 0} to S{sub 2}; sequence S{sub 0} has a thick turbidite sandstone at the base (Rio Segredo Member) that pinches out towards the eastern margin and even disappears in the Mafra outcrop area. Sequence S{sub 1} varies from a thin fluvial-estuarine system to a thick turbidite sandstone of a channelled fan system; S{sub 1} upper shaly system tract is marine in well PP-11, and it is glacially influenced in well PP-10. Sequence S{sub 2} is a thick sandstone body of shallow marine origin, but restricted to one well (PP-11); its upper shaly tract is dominated by massive siltstones intercalated with thin, distal tempestites. The 'lower' Triunfo Member (or 'Taciba- Triunfo transition') begins with the arrival of deltaic clastics of sequence S{sub 3} lower tract, coarsening-up from medial- to proximal delta front sandstones. Sequence S{sub 4} is quite similar to S{sub 3}, both showing sandstone pro gradation from north to south, as opposed to the southwest-sourced transgressive diamictites. Sequence S{sub 5} consists of fluvial deposits at well PP-12, and two transgressive cycles from wells PP-11 to PP-9, each one of them composed of fluvial-estuarine to marine systems. Well PP-10 is an exception, where the lower cycle presents de glaciation to marine deposits. (author)

    This paper will present the pioneering project of electric energy generation from renewable sources 'GASEIBRAS - Nationalization of the Biomass Gasification Technology and Formation of Human Resources in the Amazon Region', recently approved by the National Advice of Scientific and Technological Development (CNPq) and for the Ministry of Mines and Energy (MME). The GASEIBRAS project intends to use the experience previously acquired in the project GASEIFAMAZ - Comparison between Existing Technologies of Biomass Gasification in Brazil and Exterior and Formation of Human Resources in the North Region, sponsored by FINEP/CTENERG, to develop and construct a 20 kWe biomass gasification system, with total national technology, easy to operate and to maintain, and fed with local available biomass residues. Apart from contributing for the development of the national technology, this project will provide the sustainable development of the isolated communities in the Amazon region. The ongoing development of this project will enable to consolidate the national biomass gasification technology for electricity generation. The implemented prototype will allow the response of this project in other regions of the country, due its tailor made characteristic to attend to small isolated communities, thus supplying decentralized energy from renewable sources, to Amazon region.

    A gamma spectrometry profile was carried out along BR174 highway, that crosses some lithostratigraphic units of the North portion of the Sedimentary Basin of Amazon. Measurements in situ were realized in 116 points, 1 km apart, using a GAD-6 gamma-spectrometer and samples of rocks and soils were collected in geologically representative points, for gamma measurements using a shielded detector of NaI(Tl) available in the Nuclear Geophysics Laboratory of IAG/USP. The criterion used for evaluating the reliability degree of the concentration values of eU (ppm), eTh (ppm) and %K was to establish mathematically detection limits, for all measurement points. Every these points had been located using GPS with accuracy of 50 m to become possible a future detailed study. The purpose of matching portable gamma spectrometer and laboratory determinations was to compare the 2 techniques, using the criterion of detectability limits, and to verify the influence of {sup 222} Rn atmospheric radioactive gas in field measurements. In the case of portable detector, it allows fast measurements and the sensor 'sees' a big volume of material (rock, soil...), that makes it more representative. In some situations where atmospheric phenomena of thermal inversion occurs, measurement can be affected by the {sup 222} Rn cosmic background. Presence of radon daughter elements, associated with aerosols, in this tropical environment (high values of temperature and humidity), where the speed of the wind that could exhaust this gas is practically zero. It is observed that the values of concentration in the some points, got with these 2 techniques, have the same trend, and the stretches where peaks of concentration of K also occur and U and Th are associated with the presence of granite out corps, great boulders, and clay soils from weathering of these rocks.

    There is only scarce information on the presence of radionuclides in water for public consumption in Brazil. A recently issued federal regulation requires that waters from public supplies be screened to determine their content of alpha and beta emitters. In order to comply with this requirement the present work was carried out with the purpose of determining the concentration of natural uranium, {sup 222} Rn and {sup 210} Po in water supplies in the metropolitan region of Recife, Brazil. The analyses were performed in 17 points of supply of superficial water and 94 points of groundwater supply. The concentrations of uranium were determined by the fluorimetric method, whereas the liquid scintillation method was used to determine the concentration of {sup 222} Rn. Polonium-210, on the other hand, was determined by alpha spectrometry, following its spontaneous deposition on copper disks. The water analyzer presented uranium concentrations varying from 35.3 to 1146.5 mBq/L for superficial resources and from 20.2 to 919.15 mBq/L for underground sources. The concentration of uranium in superficial water showed significant correlation with some parameters such as conductivity, alkalinity and total hardness, as well as, with the concentrations of Ca, Mg, Cl, K, SO{sub 4} and Mn. No correlation, however, was shown with the concentrations of Fe, NO{sub 2} and NO{sub 3}. The concentrations of {sup 222} Rn varied from 5.3 to 83.7 Bq/L in the groundwater analyzer. Radon concentration was not measured in superficial water due to the high emanation rate of radon in open air conditions. As far as {sup 210} Po is concerned, the analyses showed concentrations ranging from <22 mBq/L (the lowest limit of detection) to 57.4 mBq/L for superficial water and from <22 to 813 mBq/L for ground water samples. The concentrations of {sup 210} Po did not show and correlation with physico-chemical parameters. The average concentrations of uranium and {sup 210} Po in superficial water were of 44.7 mBq/L, respectively. These values correspond to effective doses of 5.8 x 10{sup -4} mSv/yr and 4.5 x 10{sup -2} mSv/yr, for uranium and {sup 210} Po, respectively. The average values for the concentrations of uranium, {sup 222} Rn and {sup 210} Po in ground samples, on the other hand, were 106.6 mBq/L, 24,3 Bq/L and 30 mBq/L, respectively, corresponding to effective doses of 8.0 x 10{sup -4} mSv/yr, 1.3 mSv/yr and 0.47 mSv/yr, respectively.

    Radioactive pollutants can cause impact on the environmental quality of soils and pose a risk to human health. The release of radioactive materials through nuclear testing or nuclear accidents cause the deposition of radionuclides on the ground,· it may be leached by rain, transported to the sources of natural waters and absorbed by the soil fauna and flora, and thus enter the human food chain. Radioecological studies have shown that soils with low pH, low organic matter content and low fertility are more vulnerable to contamination by {sup 137}Cs, since the transfer to plants is high. In this study, we aimed to assess and map the vulnerability to contamination by {sup 137}Cs surface horizons of the soils from the Pantanal and propose mitigation measures adapted to the regional scenario to optimize radiological protection of agricultural areas. Therefore, selected soil profiles located in the municipality of Jaraguari, state of Mato Grosso do Sul, and applied the conceptual model developed by Picanco Jr (2012), which was used in the reference values of the factor of soil-plant transfer (FT) for {sup 137}Cs in corn, related soil variables (pH, CTC and exchangeable K) and relevance of parameters and variations of amplitudes for each value range of FT. The application of this conceptual model established to detect the vulnerability of soils to radioactive contamination generated maps vulnerability showing that the region is very heterogeneous as this criterion, showing low levels of vulnerability for most of the region and in some areas, extreme vulnerability. This result identified the Pantanal as one of the less vulnerable to the radioactive contamination, but the sparse areas of extreme vulnerability can lead to contamination of subsoil and a significant spread of contamination via groundwater. This conceptual model, which defines vulnerability classification, is a first step for the study and determination of a numerical index of vulnerability to {sup 137}Cs soil and can be used in the task of remediation in case of rural areas by accident and {sup 137}Cs contamination establishing geographic areas where we should prioritize treatment due to a greater vulnerability.

    Deep Andean earthquakes are a suitable source of high-frequency P-waves (with good signal to noise ratio up to {approx} 10 Hz) that can be used to obtain high-resolution receiver functions at stations in intra-cratonic basins in Brazil. Receiver functions (Gaussian width 20) at five stations in the Bebedouro seismic area (NE Parana Basin) were calculated using the time domain deconvolution of Ligorria and Ammon (1999). Inter-station Rayleigh wave phase velocities were measured using local earthquakes. Joint inversion of receiver functions and Rayleigh phase velocities provided reasonably well constrained S-wave velocity profiles. Shallow seismic refraction surveys were used to fix the velocities of the surface layers during the inversion. The area is characterized by a thin surface layer of sandstones ({approx}60 m), followed by a {approx}500 m thick basalt layer. Beneath the basalts, low-velocity layers define another sedimentary sequence. These features are consistent with the expected values based on well data at regional distances and confirm the usefulness of high-frequency receiver functions to study sedimentary basins. (author)

    Currently there are few applications on the risk analysis procedures related to radiation therapy, especially in the practice of radiotherapy. The objective of this study was to analyze the perception of risk levels present in the practice of teletherapy (only the use of linear accelerators), through a form based on the risk matrix concept and a database (SEVRRA) containing information about the processes related to routine teletherapy. Was delivered to a medical physicist for each service, a form containing information relating to teletherapy procedure and an annex indicating how to fill it properly. The results show that, according to the opinion of 16 medical physicists participants, six of these analyzes showed a prioritized risk percentage above 50%, other five had a risk of prioritized percentage between 0 and 50%, and the remainder had a risk percentage prioritized null. Two steps groups had the highest incidence of cases classified with high and very high risk: records and treatment planning group and equipment group. It was then possible to find the most risk processes these steps groups. Finally, we performed an analysis of the effectiveness of the controls present in the proposed form. The four most incidents controls, three of them had a percentage efficiency above 80%, and viable its continuous use in the analyzed services, as well as serving as a recommendation for use in other services not analyzed. This study showed that, although there are considerable histories of accidents for teletherapy procedure, you can not only identify the risks of higher expression but also mitigate them, based on actions and appropriate recommendations for each case analyzed properly.

    Recent studies have demonstrated that the infra-red laser can cause alterations in thyroid glands. Their normal activity must be preserved, as they produce the thyroidal hormones triiodothyronine (T{sub 3}) and thyroxine (T{sub 4}), that stimulate the oxidative metabolism, essential to maintain a healthy organism. The increase or diminution of these hormones results in alteration of the mitochondria's activity, that determines the secondary effects in the metabolism. The purpose of this study was to evaluate if there was any alteration of the thyroidal hormones plasma levels under irradiation from infra-red laser, with energy density of 4J/cm{sup 2}, in the region of thyroid glands of male mice. It was concluded that there was an hormonal level alteration statistically significant between the first day of irradiation and seven days after the last application. Histological studies showed that there was no morphological changes in histological sections of thyroid glands. The optical absorption spectroscopy of mice's serum presented a peak at approximately 280 nm, attributed to tyrosine (this is the amino acid compounding these hormones). (author)

    The objective of the present work was to characterize two new Clay deposits (A and B) from the south region of Amapa state, aiming to establish their adequate uses as ceramic raw materials and to promote the potential of the ceramic industry in the region. Were prepared specimens by uniaxial pressing, being applied a two phase pressing of 13,4 MPa and 20 MPa, respectively. The samples were dried in an oven at 110 deg C, and submitted to burning at 850, 1000 and 1200 deg C. Were determined linear firing shrinkage, water absorption, apparent porosity and modulus of flexural modulus of rupture, as well as mineralogical evolution after burning. Finishing, the microstructure of the sintered clay at 1200 deg C was evaluated in a scanning electron microscope. The results showed that the clay A presented a better mechanical development, having a red coloration and, therefore, potential to the red ceramic industry. On the other hand, the clay B presented a light color, due to a low content of iron oxide and, therefore, having potential as refractory raw material. In general, one clay is suitable to be used in white ceramic and the other in red ceramic. (author)

    This work deals with the measurement of radioactive lines in powdered milk, with high resolution gamma spectrometry, using a HPGe detector with relative efficiency of 10%, coupled to the electronic nuclear chain and a multichannel card of 8192 channels. Some tests were realized before beginning the measurements. The first of them was to define the shield to be used, making several measured with different shields according to the available materials, opting finally for a shield composed of bricks of lead (10 cm thickness), plates of iron (4nm thickness) and of aluminum (2 mm thickness). Four different geometries for the samples recipients were tested, and the Marinelli beaker of 2,1 liters totally filled was the one which supplied the best peak/background ratio. A statistical inference was also realized to determine the sampling that represents each one of the lots of milk to be measured, resulting in a number of 6 samples, for a confidence level of 95%. Two different kinds of powdered milk produced at Londrina were analyzed, Integral Powdered Milk Cativa and Integral Powdered Milk Polly. The samples were properly put in the Marinelli beaker of 2,1 L, sealed and kept for 40 days to reach the secular equilibrium. The counting time for each measurement was two days. It was possible to identify the radionuclides {sup 40} K, {sup 137} Cs and {sup 232} Th (from {sup 208} Tl), whose activities were calculated according to the International Atomic Energy Agency norms (IAEA, 1989). The detector efficiency was measured using calibrated samples, prepared with the certified reference materials IAEA-326 and IAEA-375. Corrections for self-absorption were accomplished, based on measures of samples with different densities. The results obtained for the powdered milk Cativa were: 464{+-} 12 Bq/kg for {sup 40} K, 3,46 {sup {+-}} 1,05 and 0,46 {+-} 1,05 and 0,46 {+-} 0,16 Bq/kg for the minimum detectable activities of {sup 137} Cs and {sup 232} Th, respectively. For the milk Polly, the results were: 452{+-}10 Bq/kg for {sup 40} K, 3,19{sup {+-}} 0,63 and 0,32{sup {+-}} 0,12 Bq/kg for the minimum detectable activities of {sup 137} Cs and {sup 232} Th, respectively. The statistical analyses performed checked the measurements repeatability by means of the Tukey's average comparison test. A correlation analysis between standard deviations and the mean showed the absence of significant systematic deviation. Comparison the results obtained with literature, it was demonstrated that the values of the activities found are within the normal levels of radioactivity for this kind of product and below the maximum permissible levels established by CNEN, that is, the analyzed milk can be normally consumed. On the other hand, the implemented methodology present a good performance, faced to the available experimental conditions. (author)

  20. The use of lichens as bioindicators of atmospheric contamination by natural radionuclides and metals in a region impacted by TENORM; Utilizacao de liquens como bioindicadores de contaminacao atmosferica por radionuclideos naturais e metais em regiao impactada por TENORM

    The main aim of this thesis is to study the possibility of using lichen as bioindicator of atmospheric pollution in regions contaminated by radionuclides, metals and rare earth elements. Two regions were chosen, one in Pirapora do Bom Jesus, where a tin and lead industry is located, and a second one in Cubatao, where a phosphate fertilizer industrial complex is located. The two industries chosen are considered as TENORM - Technologically Enhanced Naturally Occurring Radioactive Material, since they can cause a significant increase in the natural radionuclides concentration in the industrial process, and consequently a potential increase in the radiation exposure in products, byproducts and residue. To achieve this aim, the radionuclides {sup 238}U, {sup 226}Ra, {sup 210}Pb, {sup 2'}3{sup 2}Th and {sup 228}Ra, rare earth elements and metals were analyzed in samples of raw material and residues from the installations, lichens and soils. Lichens and soil samples were analyzed by instrumental neutron activation analysis for the determination of uranium, thorium, rare earth elements and metals. The radionuclides {sup 226}Ra, {sup 228}Ra and {sup 2}'1{sup 0}Pb in soil samples were determined by gamma spectrometry and in lichen sample by radiochemical separation and gross alpha and beta counting on a gas flow proportional counter. The concentrations of {sup 238}U (from 19 to 473 Bq kg{sup -1}), {sup 226}Ra (from 21 to 265 Bq kg{sup -1}), {sup 210}Pb (from 401 to 1461 Bq kg{sup -1}), {sup 232}Th (from 15 to 574 Bq kg{sup -1}), {sup 228}Ra (from 176 to 535 Bq kg'-{sup 1}), rare earth elements, Hf and Ta determined in lichen samples around the tin and lead industry show an enrichment in these elements. Therefore, the lichens can be used as a fingerprint of the atmospheric contamination. The results obtained for the lichen samples, in the Cubatao region, present a fingerprint mainly of {sup 210}Pb, from industries of the region. The results obtained in this study showed that the lichens can be used as bioindicators of atmospheric pollution by radionuclides and trace elements. (author)

    Rio de Janeiro Petrochemical Complex (COMPERJ) will be installed in the north region of Itaborai city. The start of COMPERJ operations is foreseen to 2012. Because of the intensification of industrialization and urbanization processes, the implantation of COMPERJ will bring environmental modifications for Itaborai city and neighbors areas. Thus, meteorological and air quality monitoring was initiated in February of 2007 with the intention of carrying out a characterization of air pollution in this area, before COMPERJ operations. In this work are presented the results found in campaigns performed of February of 2007 until April of 2008. The meteorological monitoring disclosed that the meteorological parameters have varied enough throughout the months, but these are representative of a global behavior of the studied area. Monitoring of air quality has shown that atmospheric levels of monitored pollutants has been generally below of Brazilian air quality standards. This fact corroborates the basic aspect of the present study: identification of the concentrations 'background' in the studied area. Throughout the period of monitoring, the primary air quality standard for ozone has been reached. Observations of meteorological parameters indicate that this fact is associated to the emissions originated from Sao Goncalo, Niteroi and Rio de Janeiro cities. (author)

    To determine the concentration of heavy metals and other contaminants in soils, aimed at evaluating the environmental impact, the use of the distribution coefficient is required (Kd), defined as the relationship between the concentrations adsorbed and in solution. The objective of this study was to determine the rates for the Lead and Barium metals in soil collected in Caetite, the state of Bahia, in two different depths. The importance of determining the distribution coefficient lies in the fact that being performed using a tropical soil. For the isotherms of Kd was used batch test method by adsorption to obtain the final concentrations. The first step was to determine the best ratio soil: solution obtained after equilibration time and finally the equilibrium concentration of the contaminant. Were also calculated percentages of the metal adsorbed by the soil and the amount of solute by the adsorbent. With the values obtained in experiments and using Mathematica 8.0 software, were made graphics equilibrium concentration versus quantity adsorbed (C vs. S). It can also plot isotherms for different models of Kd: linear, Langmuir and Freundlich in order to determine which adsorption model would fit best to the measured data and thus determine the distribution coefficient of the metal in the soil analyzed. The Freundlich isotherm was better adapted to the points of the two metals in both soils.

Pellets were produced by uniaxially pressing the material followed by cold isostatic pressing and finally sintering at 1600 deg C for 1,5 hours in argon. The metal content was varied in the range of 0-40 volume percent (v/o). Electrical resistivity measurements were performed in the temperature range of 25 - 700 deg C. Samples containing metallic inclusions above 25 v/o show the predominance of electronic type conducting. For samples with metallic inclusion below 25 v/o, a typically ionic conduction behavior has been observed. PSZ-Ti and PSZ-Ni samples containing 25 v/o of metallic inclusions show an insulator - conductor transition in a given temperature range. Cristobalite samples containing 30 v/o of titanium show a conductor - insulator transition also in a specific temperature range. Tests performed in an induction furnace showed that samples containing metallic inclusions above 25 v/o had self-heated when exposed to electro magnetic fields in the range of radio frequency (r.f.) Crucibles of PSZ-Ti were made by slip casting followed by sintering at 1600 deg C for 1.5 hours in argon. These crucibles were exposed to electromagnetic fields in the r.f. range and the maximum temperature reached was 1350 deg C. Microstructure characterization was performed on those materials by X-ray diffraction, EDS, optical and scanning electron microscopy. (author)

    This paper studies the utilization of the bromelia specie Tillandsia usneoides L. (Bromeliaceae) for characterization of the particle dispersion at urban and industrial regions. As a case study, a program will be developed for the monitoring the aerosols generated due to action of weather on the solid waste open sky stored and over the waste basin belonging to the INGA, located at Sepetiba bay. The identification of the stable metals will be done by the PIXE technique, and the radionuclides identification by alpha and gamma spectrometry. The preliminary results of aerosol samples collected at Ilha da Madeira region indicate the presence of particles containing Cd, V, K, Ca, Fe, Ti, Zn, Cu, Co and S. The variation in the percentage of each element at the points of collection suggests that there exist more than one aerosol source at the region

    There has been an increasing concern about current environmental issues caused by human activity, as the world searches for development. The production of electricity is an extremely relevant factor in this scenario since it is responsible for a large portion of the emissions that cause the greenhouse effect. Due to this fact, a sustainable development with alternative energy sources, which are attractive for such purpose, must be proposed, especially in places that are not supplied by the conventional electricity grid such as many communities in the Northeast Brazil. This work aims to calculate the environmental cost for the alternative sources of energy - solar, wind and biomass - during electricity generation, and to estimate the economic feasibility of those sources in small communities of Northeast Brazil, considering the avoided costs. The externalities must be properly identified and valued so the costs or benefits can be internalized and reflect accurately the economic feasibility or infeasibility of those sources. For this, the method of avoided costs was adopted for the calculation of externalities. This variable was included in the equation developed for all considered alternative energy sources. The calculations of economic feasibility were performed taking the new configurations in consideration, and the new equation was reprogrammed in the Programa de Calculo de Custos de Energias Alternativas, Solar, Eolica e Biomassa (PEASEB). The results demonstrated that the solar photovoltaic energy in isolated systems is the most feasible and broadly applicable source for small communities of Northeast Brazil. (author)

    This work discusses the use of numerical prediction using ensemble as boundary condition in pollutants dispersion models, applied in a hypothetical case of an oil spill occurrence in Itaguai Port. The Princeton Ocean Model (POM) has been used to simulate hydrodynamics and NICOIL Eulerian model to forecast oil spill dispersion, and ensemble wind forecast from Global Forecast System (GFS), aiming to assess the importance of this parameter variability in oil dispersion at sea. The wind scenarios using ensemble members has showed significant dispersion when compared to control simulation, demonstrating that the uncertainty in the atmospheric modeling can generate considerable variations in the placement of the final spot of oil. The region of interest was the Sepetiba Bay, located on the southern coast of the Rio de Janeiro state; because of port operations carried out around the Port of Itaguai where they can, eventually, oil leaks occur.

    This paper objective was to settle the electric energy consumption in the countryside and the agriculture and cattle raisin production value in the counties of the Rural Development Office (EDR) of Botucatu, in the period of 1990 to 2000, trying to establish an analysis pattern to do future studies in other regions. This pattern could be used as an analysis instrument to make decisions to implement programs that look for an increase of use of electric energy as an input to join value to the rural product. In conclusion the data adjoined as EDR region do not present enough information to the relation between the production rough value and the electric energy consumption, being necessary, therefore, its disaggregation in counties.

    Submarine groundwater discharge (SGD) and recycled seawater can provide chemical constituents to coastal zone, representing an important material flux pathway from land to sea in some areas. Geochemical tracers, like {sup 222} Rn and {sup 226} Ra, are advantageous for regional-scale assessment of SGD, because their signals represent values integrated through the water column that removes small-scale variations. These radionuclides are usually enriched in groundwater compared to seawater, can be measured at very low concentrations and are conservative. This work reports preliminary results of a study carried out in a series of small embayements of Ubatuba, Sao Paulo State-Brazil, covering latitudes between 23 deg 26{sup '}S and 23 deg 46{sup '}S and longitudes between 45 deg02{sup '}W and 45 deg 11{sup '}W. The main aims of this research were to set up an analytical method to assess {sup 222} Rn and {sup 226} Ra activities in seawater samples and to apply the excess {sup 222} Rn inventories obtained to estimate the submarine groundwater discharge. Measurements made during 2001/2002 included {sup 222} Rn and {sup 226} Ra in seawater, {sup 222} Rn in sediment, seawater and sediment physical properties. (author)

    The Amazon Submarine Fan, part of the Amazon Mouth Basin, is strongly affected by shale tectonics. Preliminary analysis of about 9.000 Km of multichannel seismic lines allowed us to map three main structural domains: a proximal extensive province largely dominated by seaward-dipping listric normal faults soling into a decollement level (mobile shale, Neomiocene in age) and associated rollovers; an intermediate rigid gliding province, and a lowermost compressive front, dominated by thrust faults. An important point about gravity tectonics in this area is that the morphology of the base of the mobile level seems to have influenced the development of the structural styles. For instance, listric faults lying at the upslope limit of the extensional province are arranged along a step-like morphology of the decollement level. As well as that, we observed that the gradient of the decollement level is more important on the northwestern portion of the fan, where the distance between the extensive and the compressive province is larger (of about 40 Km) than on the southeastern portion of the fan (about 25 Km large). Then, on the basis of the basal level gradient and the structures disposition we can segment the fan area into two structural compartments: a northwest and a southeast compartment. (author)

    Tillandsia usneoides L. is an epiphytic bromeliad that lives on trees or other kinds of inert substrates, absorbing water and nutrients directly from the environment without roots. Due to its morphological and physiological characteristics, this species accumulates the pollutants present in the atmosphere. In the present work, Tillandsia usneoides was used as a bio monitor of metal atmospheric pollution in Sao Paulo, Brazil, which is the biggest city in South America with a population of 18 million inhabitants and a strong industrial activity. The urban area is polluted by industrial emissions but, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB), the governmental agency of air quality control, regularly occurring emissions from about 7.8 million motor vehicles provide the principal source of air pollution. The Tillandsia samples were collected from an unpolluted area and were exposed bimonthly in 10 sites of the city with different pollution levels and in a control site. After exposure, trace metals were analyzed in the plant by instrumental neutron activation analysis and ICP-MS (Pb, Cd, Co, Cu, Ni, Sb e V). The results of the investigation showed a notable concentration of Co and Ni in the plants exposed in an industrial area where there is a metal processing plant, which produces about 600 tons/year of Co and 16,000 tons/year of Ni. Copper and chromium were equally distributed in industrial regions and in sites near heavy traffic avenues, suggesting that these elements can be associated to both vehicular and industrial sources. A high accumulation of Cd in the plant exposed in industrial areas indicates industrial activities as the main source of this element. For Pb, no evident sources could be identified so far as it was spread evenly along the monitoring sites. Traffic-related elements such as Zn, Ba and Sb presented high concentrations in plants exposed in sites near to heavy traffic avenues (cars, buses and trucks) and may be associated to vehicular sources. For Zn, the highest contents were related to industrial zones and this element can be associated to the presence of anthropogenic emission sources. The rare earth elements, Fe and Rb, probably have soil particles as main source. (author)

    The subject of this thesis is related with work organization and working conditions in the conventional mining system used in underground coal mining. An exploratory study was conducted in a mining company located in Criciuma, Santa Catarina state, Brazil. The objective was to know how tasks were performed and which organizational and technical factors affected the safety of the workers. The study of work organization and working conditions has traditionally been a meeting ground for contributions from a variety of disciplines such as engineering, sociology, psychology, occupational medicine, and so on, and for that reason there are different approaches. Therefore one can expect some controversies over the matter. Although there are many controversies and methodological difficulties to establish causal relation with the risks observed in the production process, under many circumstances the work organization affects the working conditions and the performance of the workers. Working conditions are still a problem which needs solutions with new approaches, mainly concerning work organization alternatives, which can satisfy not only enterprises but also better working conditions.

    With a proven capacity to identify oil slicks in offshore regions, RADARSAT-1 imagery can be useful for oil exploration purposes. The paper discusses the seepage detection method at Campos Basin, offshore Rio de Janeiro State, which is responsible for 80% of the Brazilian production of oil and gas. It is known that the horizontal migration of petroleum can occurs over tens or even hundreds of kilometers, where the source rock placed in more deep locations can be linked with shallow reservoirs or traps and even reach the ocean. It means that seepage can provide information for risking petroleum charge at basin scales, and cannot have a direct relation with the geographical position of the interpreted seeps and possible filled prospects. A good understanding of the geology, and hence the petroleum systems of a basin is the key to use seepage in exploration. The work is divided into three main steps. First step were select oil seepages interpreted at Campos Basin where is found several giant petroleum fields. Second, the geology of the study area and its structural and stratigraphic features were analyzed, in order to identify possible migration pathways related to faults generated by halokinesis. Another important aspect is the presence of 'windows' or ducts in the evaporates beds allowing the contact between the section that contains source rocks and the turbidities reservoirs, that contain the majority of the oil discovers. All these features were interpreted based on a regional dip seismic line (203 - 76), and a geologic cross section with E-W orientation, showing the structure of the Marlim Field. Finally, all the information was integrated in a Geographical Information System (GIS), and then analyzed in an interdisciplinary environment, with the intention to link possible routes of oil migration to post-evaporites reservoirs or to interpreted seeps.

    This thesis is the result of geochemical, structural and radiometric investigations on radioactive pegmatites of the Borborema Pegmatitic Province in Northeast Brazil. The studied area, located in the surroundings of the city of Parelhas in the region of the Serra da Borborema, is well known for its thousands of pegmatitic bodies exploited in primitive mines called 'garimpos'. The main goal was to find an efficient, cheap and routine inspection procedure to identify the origin of commercialized radioactive columbite-tantalite (coltan) ore. The Brazilian Nuclear Energy Agency (CNEN) controls uranium commerce and nuclear activity in Brazil. Without an effective method to characterize coltan ores from different localities it is impossible to control the trade. The here presented new method was developed by correlating structural features of these pegmatites with the geochemical behavior of their coltan samples. It was found that the variation of the ratio U/Th versus Nb{sub 2}O{sub 5}/Ta{sub 2}O{sub 5} provides geochemical signatures (analytical fingerprints) for the source location of such ore. A test of the new method with coltan samples of commercial batches from the Brazilian states Amapa and Rondonia also generated distinct geochemical signatures. A radiometric survey (CPS) was carried out in several mines and pegmatites to study the environmental impact of gamma radiation. It included in situ measurements of pegmatite walls, host rocks, soil, and accumulated water and revealed that gamma emitters are hardly solubilized and environmental gamma radiation therefore generally is not enhanced to a dangerous level.

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr{sup 87} / Sr{sup 86} initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle 201 refs., 130 figs., 6 tabs., 2 maps

    This thesis is the result of geochemical, structural and radiometric investigations on radioactive pegmatites of the Borborema Pegmatitic Province in Northeast Brazil. The studied area, located in the surroundings of the city of Parelhas in the region of the Serra da Borborema, is well known for its thousands of pegmatitic bodies exploited in primitive mines called 'garimpos'. The main goal was to find an efficient, cheap and routine inspection procedure to identify the origin of commercialized radioactive columbite-tantalite (coltan) ore. The Brazilian Nuclear Energy Agency (CNEN) controls uranium commerce and nuclear activity in Brazil. Without an effective method to characterize coltan ores from different localities it is impossible to control the trade. The here presented new method was developed by correlating structural features of these pegmatites with the geochemical behavior of their coltan samples. It was found that the variation of the ratio U/Th versus Nb{sub 2}O{sub 5}/Ta{sub 2}O{sub 5} provides geochemical signatures (analytical fingerprints) for the source location of such ore. A test of the new method with coltan samples of commercial batches from the Brazilian states Amapa and Rondonia also generated distinct geochemical signatures. A radiometric survey (CPS) was carried out in several mines and pegmatites to study the environmental impact of gamma radiation. It included in situ measurements of pegmatite walls, host rocks, soil, and accumulated water and revealed that gamma emitters are hardly solubilized and environmental gamma radiation therefore generally is not enhanced to a dangerous level.

    This work was conducted in the city of Campos dos Goytacazes/RJ, in which four residual soils collected in the region were technologically characterized. We sought to determine their properties, such as analysis of the colors after firing, aiming at its use in ceramic art. To this end the tests were conducted in the laboratories of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) and that are granulometry (by sieving and sedimentation), specific mass of grains, chemical analysis by X-ray fluorescence, diffraction mineralogical identification X-ray, differential thermal analysis and thermogravimetry. The soils were analyzed before drying at 110 deg C and after burning the different temperatures (500 deg C 750 deg C and 950 deg C). The analyzed results showed the physical composition, chemical and mineralogical of raw material. After burning was possible to observe several color variations. (author)

    The most common sequelae in head and neck cancer patients submitted to radiotherapy (60Cobalt) is postirradiation hypo salivation. This leads to a change in oral physiology, and, as a consequence, the irradiated individual is susceptible to infections and caries lesions. The aim of this study was to evaluate the behaviour of stimulated whole saliva flow rate (SWSFR) during and after radiotherapy treatment for head and neck cancer by lateral opposed fields. Six samples of mechanically stimulated whole saliva were collected of each individual and evaluated by gravimetric method.The first sample was collected before radiotherapy; the second one after 1500 cGy dose; the third one after the last dose of treatment and the remainder samples in intervals of subsequent two months up to six months after the end of treatment. The SWSFR decreased in 50% after a dose of 1500 cGy (1/4 of received treatment). After radiation therapy, the SWSFR was 0,33 ml/min and after six months was 0,20 ml/min. These values represented, respectively, a decreasing in 64% and 78% of initial values (ANOVA, Tukey's Test p<0.05).Based in these results, the authors concluded radiotherapy when applied in malign neoplasms of the head and neck region by lateral opposed fields was able to decrease significantly salivary flow rate. Intensive preventive dental care during and after radiotherapy seems to be an useful tool to avoid radiation caries and their complications. (author)

    This paper aims to present a systemic model for analysis of the expansion and grow up of the natural gas distribution pipeline in a city. This methodology integrates the understanding of the urban dynamics to the strategies of expansion in the natural gas distribution network, through the grouping of information such as family income, demographic density and construction area, percentage of land use, number of households as well as commercial, service and industrial establishments, number of real state as well as indicative information released by the Urban Plan of the city regarding the increments in the peripheral districts. Relating the gas consumption esteemed by each type of land occupation and the cost for expanding the gas distribution network, the model will indicate, for each neighborhood, the viability of implementing a gas network as well as the places with potential for growing density in the existing gas distribution system. The aim is to propose an integration of aspects of city dynamics and new energy source development, taking the advance of natural gas in Sao Paulo Metropolitan area as a specific case study. Through the analysis of highly industrialized, residential and commercial suburbs of the City of Sao Caetano do Sul, the importance of urban parameters in the decision making process for network expansion is identified.

    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)

The collector box was made of wood, it is covered by transparent glass and thermal insulation of tire chips and expanded polystyrene (EPS). Absorber tubes were connected in parallel through the use of PVC fittings and fixed to the plate by the use of metal poles and rivets. The entire absorber received paint fiat black for better absorption of sunlight. The system worked on a thermosyphon assembly and absorber of the collector has been tested in two configurations: with the tubes facing up, directly exposed to the impact of sunlight and facing down, exchanging heat with the plate by conduction. The most efficient configuration for the connect purpose was determined. The solar collector was connected to a thermal reservoir, also alternative, low-cost forming the system of solar water heating. We evaluated thermal parameters that proved the viability of the heating system studied. (author)

    Solar collector is a device that uses solar energy for heating fluid (both liquid and gaseous) which can then be used to generate energy. This study is based on the method of calculating the global solar radiation incident on the inclined plane using data from the city of Piracicaba, state of Sao Paulo. As a result of the study it can be seen that for the city of Piracicaba the collecting area of 4.62 M{sup 2} presents solar fraction varying between 87.27% and 97.79% for heating 300 liters of water and 200 liters of water daily, respectively. Based on the results one can conclude that the savings would be about 47.74 GWh, if a collection area of 360 thousand m{sup 2} (0.36 km{sup 2}) were fully exploited, which represents savings of approximately R$ 15.86 million per year for the municipality.

    Full Text Available The production of the metropolitan peripheries in Latin America has been characterized by the development of urban, residential and commercial enclaves. These enclaves encompass both large urban housing projects of social interest and subdivisions and gated communities for high-income populations. Both peripheries respond to very different social reasons but have a common spatial logic: the enclave, which deepens the isolation and social distance with its surroundings, generating segregation and fragmentation. We seek to rescue the social and spatial processes of ‘enclosing’ or ‘insularity’ in two cases: a gated community in the northeast — Zona Esmeralda— and a social housing urban complex in the east —San Buenaventura—, both bordering the metropolitan area of the Mexico Valley

    The Jacurici Complex, located in the NE of the Sao Francisco Craton, is constituted by several Cr-mineralized mafic-ultramafic N-S bodies, possible fragments of a single sill disrupted during deformation. Some works suggest it is intruded on the Serrinha Block while others consider it in the Salvador-Curaca Belt. The basement on this region is informally divided into paragneisses and orthogneisses; the latter is supposed to be younger considering it is less deformed. Petrography revealed that some of the paragneisses are alkali-feldspar granite strongly milonitized. The orthogneisses occur at the north and consist, at least in part, of monzogranites with heterogeneous deformation, locally of low temperature. U-Pb zircon dating were performed for five representative samples. Just three provided good concordia ages. A mafic rock produced a 2102 ± 5 Ma age and it is petrographically similar to the metanorites described in the Jacurici Complex, being interpreted as the record of the first pulses of the mafic magmatism. A monzogranite yielded a 2995 ± 15 Ma age, older than expected, related to the Serrinha Block. The alkali-feldspar granite yielded a 2081 ± 3 Ma age. The Itiuba Syenite and the pegmatites that crosscut the Jacurici Complex have similar ages. Considering the lack of information about the supracrustal sequence that hosts the intrusive alkaline and mafic-ultramafic rocks at the Ipueira and the Medrado areas, it is possible that part of the terrain belongs to the Salvador-Curaca Belt. We suggest that the Jacurici Complex could be intruded after the tectonic amalgamation between the Serrinha Block and the older part of the Salvador-Curaca Belt and, therefore, could be hosted by both terrains.

Determination of migration speed and the partition ratios of {sup 137} Cs in the soils of the future waste repository in Abadia de Goias, GO, Brazil; Determinacao da velocidade de migracao e das razoes de particao de {sup 137} Cs em solos da regiao do futuro repositorio de rejeitos de Abadia de Goias, GO

    The dispersion of a 51 TBq {sup 137} Cs source to the environment in Goiania city, has originated approximately 3500 m{sup 3} of radioactive waste. In order to segregate such waste in a definite form, a repository is being built in Abadia de Goias, GO near the site where it has been temporarily stored. This study had the following objectives: the determination of the {sup 137} Cs partition rate (K{sub D}) and the estimate of its migration velocity in soil samples from the site where the repository is being built. The determination of {sup 137} Cs K{sub D} was carried out by using two methods: 'batch method' and 'in-situ' method. In relation to the 'batch method'; 6 soil profiles cut into sections according to its pedologic horizons and 13 surface soil samples were collected, whereas for the 'in-situ' method 6 soil profiles with 28 cm depth were collected and each profile has been cut into 14 soil sections of a 1-3 cm range. Studies were carried out by using the 'batch method' to relate the influence from v/m and from shaking in K{sub D} determination and also studies about {sup 137} Cs adsorption reversibility in soil, time necessary for the equilibrium of {sup 137} Cs between water/soil phases to be reached and K{sub D} correlation with pedological parameters (pH values in water and clay, silt and organic material percent concentration, electrical conductivity of solution and the cation exchange - Ca{sup +2}, Mg {sup +2}, K{sup +2}, Na{sup +}, Al{sup +3}, H{sup +}). It has been noticed that in work conditions, K{sub D} has increased according to the rate increase v/m and the use of agitation in water/soil phases had no influence in K{sub D} determination. The absorbed {sup 137} Cs desorption process by water has shown to be slow but continued. Nevertheless, {sup 137} Cs cationic exchange for NH{sub 4}{sup +} has presented two steps: the first one very fast where approximately 50% of {sup 137} Cs adsorbed has been exchanged for NH{sub 4}{sup +} ions in just two days and the second one slow. Results indicate that {sup 137} Cs adsorption process in this kind of soil may be considered reversible. In using the 'batch method', it was noticed a higher {sup 137} Cs when increasing depth from soil profiles (108 - 897 cm{sup 3}.g{sup -1}). Nevertheless, {sup 137} Cs K{sub D} results point out to an average value of 430cm{sup 3}.g{sup -1}. This observation is confirmed when comparing to an average K{sub D} obtained by using 'batch method' and the K{sub D} value of 501 cm{sup 3}.g{sup -1} obtained by using 'in-situ' method. K{sub D} has just presented consistent linear correlation in relation to clay, [r=0,73]. Even though the type of clay found in the analyzed soils (caulinita) possess low adsorptive capacity, results have shown that as long as higher concentrations in clay in soil layers have been found, {sup 137} Cs K{sub D} has proportionally increased. Taking into consideration the hydrogeological medium conditions, {sup 137} Cs migration velocity found for a K{sub D} the average value obtained by using 'batch method' is 0,43 cm.year{sup -1}, whereas, for the 'in-situ' method was 0,37 cm.year{sup -1}. Assuming two meters as the minimum depth for ground water, {sup 137} Cs would take 460 - 500 years to reach it. (author)

    In this work, comparative analyses of photovoltaic power storage were made, first by the traditional means employing lead-acid batteries, and second by means of electrolytic hydrogen which was later reconverted to power in a fuel cell. In order to design the two systems, it was used a load profile of the communities in Amazon region and by means of a mathematical model, implemented in a spreadsheet, that considers the several devices and their efficiencies in order to make it possible to specify the system components. The results were employed to evaluate the economic viability of the two systems in remote communities. Considering the present conditions, it was verified that the battery system is slightly advantageous. However, it was also observed that a minor cost reduction of the electrolizers/buffer/fuel cell would make the hydrogen system very competitive, becoming the best option for photovoltaic power storage.

    In the Nova Lacerda and Conquista D'Oeste regions, Mato Grosso State, SW part of the Amazonian Craton, mafic dikes trending NNW intrude the Nova Lacerda Granite (1462{+-}12 Ma), within the Jauru Domain, in the Rondonia-San Ignacio Province (1.55 - 1.3 Ga). The mafic swarm comprises diabases, metadiabases and amphibolites. Metadiabases originated from uralitization of diabases. These rocks have tholeiitic affinity and predominant basaltic composition. Some samples are andesi-basalts. The ages of diabases and metabasites are 1380 {+-} 32 Ma and 1330 {+-} 120 Ma respectively. Geochemical data indicate that the compositional variation of diabases and metadiadases is due to fractional crystallization of evolved tholeiitic magmas. The origin of the basaltic magmas is related to a heterogeneous mantle source. (author)

    This work shows the steps for implementing a program of rational use of electricity in a pine sawmill processing through energy diagnosis and also provide an energy efficiency index, the reference consumption in Kw.h power and volume of timber in cubic meters. The study was conducted in a sawmill located at Itapeva, southwest of Sao Paulo. The region's economic potential is based on the processing of wood with the main export destination. Much of the lumber does not have advanced technology, because it may present with excessive spending power. The species used are Pinus elliottii and Pinus taeda. We collected data on the electrical installation of the mill and the main parts of the installation as tables and distribution lines and equipment engines were studied. The diagnostic results show that while the industry had a good general appearance, electrical installations and equipment using electric power for its functioning need more care, both in maintenance and in use. An energy efficiency program, if effected, could reduce the cost of the process and provides environmental benefits by less need for electric power generation. (author)

    This work is focused on the geotectonic context of the Carajas Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the techno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite Complex (EGC). This work has used digital integration products with the purpose of study the granite suite, its host rock, and the surrounded area. The digital integrated data were gamma-ray and geological data with satellite images (SAR-SAREX e TM-Landsat). The geophysics data, originally in 32 bits and grid format, were interpolated and converted to 8 bits images. The geological data (facies map) was digitalized and converted to a raster format. The remote sensing images were geometrically corrected to guarantee an accuracy on the geological mapping. On the data processing phase, SAR images were digital integrated with gamma-ray data, TM-Landsat image and the raster facies map. The IHS transformation was used as the technique to integrate the multi-source data. On the photogeological interpretation, SAR data were extremely important to permit the extraction of the main tectonic lineaments which occur on the following directions: +/- N45W, +/- N70W, +/- NS, +/- N20E, +/- N45E e +/- N75E. This procedure was done both in analogic and automatic form, being the automatic process more useful to complement information in the extracting process. Among the digital products generated, SAR/GAMA products (uranium, thorium and total count) were the ones that give the most important contribution. The interpretation of the SAR/GAMA's products added to the field campaign have allowed to map the limits of units that occur in the region and four facies of the Estrela Granite Complex were detected. The origin of the granite suite might be related to a magmatic differentiation or to distinct intrusion pulses. The use of the digital integrated products has showed to be extremely useful for basic geological mapping, especially to aid field campaign and the selection of key areas for detailed verification. As a final result, this research has allowed to propose obtained a geologic map of the Estrela Granite Complex area. (author)

    In this work it was possible to analyze the perception of risks associated with existing processes in the high-dose rate brachytherapy and teletherapy using linear accelerators of radiotherapy services in the metropolitan area of Rio de Janeiro, through the combined use of two proposed methods: FMECA and risk matrix, using a general analysis and other more specific ones. The database software (SEVRRA) was used to identify possible existing processes in radiotherapy services (brachytherapy and teletherapy) and to classify the sequence of events in risk levels. The risk levels were analyzed at each stage and sub-stage, present in the treatment of patients undergoing high dose rate gynecological intracavitary brachytherapy and teletherapy treatments with the use of linear accelerators applying electron or photon beams in order to establish recommendations to the risks of highest priority for each case. The results show that although the procedure of high dose rate brachytherapy be automated and less susceptible to errors or failures, daily, one can still find considerable amounts of processes with worrying levels of risk perception. The processes that are more subject to radiological accident risks was associated with procedures, for of which the majority of the failures record and planning step of the treatment. The controls analyzed showed low efficiency, warning of the need to seek and implement new more efficient controls in routine brachytherapy for each participant service. About teletherapy procedure it was found that most of the failures were related to the registration and planning of treatment and equipment stages. The controls analyzed to teletherapy showed a poor result with a first type of analysis performed by suggesting a new type of more appropriate analysis. With a second type of analysis, these controls could be better analyzed and showed an order of importance according to a percentage of efficiency. Controls such as 'Double-check', 'Weekly image portal' and 'Weekly medical review of patients', were highlighted as the most present and effective in routine radiotherapy procedure. These results have great relevance for this type of methodology, since their practical application, together with its potential risk identification and classification, confirm their feasibility of use in routine services in the metropolitan area of Rio de Janeiro, as well as in other locations, seeking to meet national and international recommendations for safety and radiation protection.

    Analytical procedures used for determining the concentrations and isotope composition of strontium in subsurface waters, by mass spectrometry, are described. Sampling was performed in coastal plateaus, salt marsh and mangrove environments in the coastal region of Para. Coastal plateau waters have {delta}{sup 87}Sr between 1.51 and 6.26 per mille and Sr concentration bellow 58 ppb. Salt marsh waters show {delta}{sup 87}Sr between 0.55 and 0.90 per mille and Sr concentration between 93 and 114 ppm, while mangrove waters have {delta}{sup 87}Sr per mille around zero and Sr concentration above 15 ppm. Differences in the {sup 87}Sr/{sup 86}Sr ratio in these subsurface waters are detected, as well as seasonal variations in the coastal plateau waters. (author)

    The image acquisition methods applied to nuclear medicine and radiobiology are a valuable research study for determination of thyroid anatomy to seek disorders associated to follicular cells. The Monte Carlo (MC) simulation has also been used in problems related to radiation detection in order to map medical images since the improvement of data processing compatible with personnel computers (PC). This work presents an innovative study to find out the adequate scintillation inorganic detector array that could be coupled to a specific light photo sensor, a charge coupled device (CCD) through a fiber optic plate in order to map the follicles of thyroid gland. The goal is to choose the type of detector that fits the application suggested here with spatial resolution of 10 {mu}m and good detector efficiency. The methodology results are useful to map a follicle image using gamma radiation emission. A source - detector simulation is performed by using a MCNP4B (Monte Carlo for Neutron Photon transport) general code considering different source energies, detector materials and geometries including pixel sizes and reflector types. The results demonstrate that by using MCNP4B code is possible to searching for useful parameters related to the systems used in nuclear medicine, specifically in radiobiology applied to endocrine physiology studies to acquiring thyroid follicles images.

    The Foz do Areia reservoir, under certain combinations of events, may influence flood levels in the cities of Uniao da Vitoria and Porto Uniao, located upstream. To avoid this phenomenon constitutes the main purpose of the hydraulic operation of the Foz do Areia and Segredo reservoirs, after dams safety. To satisfy these objectives, first have to correctly quantify these effects by means of studying the hydraulic behavior of the river reach between the cities and the Foz do Areia reservoir. A description of the recent version of these studies is shown, which demanded significant efforts in modeling and obtaining topographical and hydrological data. A more critical scenery has resulted as compared to former studies, emphasizing the importance of the methods and parameters for the hydraulic operation proposed in this paper. (author)

    Studies show that some regions of the Amazon region suffer mercury (Hg) impacts as a direct result of both natural and anthropogenic processes. Jau National Park (PNJ) is the only National Park in Brazil that protects an entire black water basin (Jau River), flood land and tropical reserve. These conditions favor Hg methylation in the aquatic biota. This in turn, exposes living on the river populations to Hg contamination as well as the adjacent regions. Preliminary studies of pre-school children diets from PNJ communities have shown that these diets have a worrisome high Hg content. The present study assessed total Hg content, micro nutrients (Ca, Fe, K, Na, Se and Zn) and macro nutrients (proteins, lipids, ash, energy, carbohydrate) in pre-school diets in the PNJ and surrounding communities. Furthermore, total and Me Hg levels were also determined in hair samples of these children as well as those living in several neighborhoods of the city of Manaus. Included in this determination were the fish most consumed by these populations. From these results it was possible to evaluate the nutritional content of the diets and the exposure of the children to Hg and Se Hg. Cold vapor atomic absorption spectrometry was used to quantify total and Me Hg. Micro nutrient determination was performed using neutron activation analysis technique (NAA) and Macro nutrient through AOAC methodologies (USA). All analytical methods were developed and validated for precision and accuracy by means of reference materials analyses with certified values for the determined elements. Furthermore, the uncertainty sources for Hg and Me Hg determination were assessed and the expanded uncertainties were calculated. Total Hg levels in diets and total and Me Hg levels for hair samples, were well above those values found in different localities of the Amazon region. This also holds true for those surrounding areas of the JNP. For many children Hg intake values passed the 5 mug Hg/body weigh/week (PTWI). Children of the city of Manaus presented much lower Hg levels in hair samples in contrast to those of the PNJ even though both groups shared the same ecosystem. It can thus be concluded that populations that have a wider choice of food products for protein, have a lesser intake of fish and as a consequence less Hg intake. Obtained NAA results furnished reliable concentration values for important nutritional elements, mainly Ca, Fe, K, Na, Se and Zn. From these values the daily intake was calculated and compared to the DRIs (Dietary reference intakes). In general, the diets analysed in this study presented inadequate and deficient protein-caloric levels, confirming these populations high risk and vulnerability to nutritional deficiencies and to Hg exposure. Several external factors can obviously influence the vulnerability of these populations to the toxic effects to Me Hg such as: age, sex, health and nutritional status, intake and dietary interaction. In order to evaluate the influence of the cooking processes (in natura, cooked, fried, baked) regarding micro nutrient and total Hg losses, in order to contribute to future nutritional studies, Hg levels and micro nutrients in fish species most consumed by Manaus residents and surrounding communities were assessed. Micro nutrients and Hg loss variability through the different cooking processes seem to be more related to fish species rather than cooking process. Furthermore, predatory species presented higher Hg and Se levels as was expected. The Hg and Se correlation in fish is also discussed. Although research shows a high Hg background in the Amazon the continuous exposure through food can in time worsen especially in communities that do not have diet diversification, have serious nutritional deficiencies and whose diets are mainly fish. It is hoped that this study can also contribute to future public political actions and policies in terms of reducing dietary hazards due to Hg and Me Hg exposure. (author)

    This work consists of data integration of uranium concentrations, parts per million (ppm), associated to the different rock formations belonging to Parana Basin in the region of Santa Maria, in the Rio Grande do Sul state southern Brazil. This study was developed from primary data generated by the Companhia de Pesquisas de Recursos Minerais as part of the AERO/Camaqua; Project, 1010 code series, digitalized in the 1997 Geosoft XYZ format. Through an irregular net of values of uranium concentration, with 25806 observations were spatially oriented by Universal Transverse Mercator/ UTM coordinates. Which were varied from west to east 206190 to 276813 E, and from north to south 6670888 to 6735665 N, totalizing an area of 4574.75 km{sup 2}. Using Statistica 7.1 software licensed to the Department of Statistics at the Federal University of Santa Maria, the mean values of and the confidence limits with alpha = 0.05, the standard deviations of uranium concentrations for each rock formation. The comparisons between the mean values were made through the Tuckey's Test and the spatial variation of the concentrations in relation to the geographical coordinates were adjusted to a polynomial model. The results obtained showed that the uranium concentrations occur in a distinct way in the different geological formations studied (aluvionar unconsolidated sediments, sandstones and igneous volcanic acid and basic rocks). The uranium variable, when spatialized in relation to the geographical coordinates UTM were adjusted to a second order polynomial model. (author)

    The coastline between Sao Sebastiao and Ubatuba cities and the shores of Sao Sebastiao, Anchieta and Mar Virado islands (Sao Paulo State, Brazil) are crosscut by several small swarms and isolated dykes trending N55E. The main rock types range from basic to intermediate, but also a conspicuous variety of alkaline lamprophyres occur side by side with the main group. The thickness of the basic to intermediate dykes vary widely, from a few centimeters to several metres, while the lamprophyres are a few tens of centimeters thick. The objective of this thesis is the petrographic, mineralogic, petrochemical and isotopic characterization of the basic and ultrabasic dykes that occur between the Sao Sebastiao and Ubatuba cities (State of Sao Paulo), also including some occurrences from the Sao Sebastiao, Mar Virado and Anchieta islands and from the Bairro Alto region (Folha de Natividade da Serra). The petrogenetic model presented is based in the national and international bibliography. (author) 146 refs., 44 figs., 24 tabs.

    The Lusitanian Basin (Portugal) is located on the western margin of the Iberian Plate with maximum sedimentary thickness around 5 km. In spite of containing promising petroleum systems and more than a hundred wells, its hydrocarbon generation potential has not been fully evaluated yet. These sediments range from upper Triassic to upper Cretaceous, mainly from the Jurassic age. The Lower Jurassic is particularly well represented in the Lusitanian Basin, specifically in the Peniche region, where there are more than 450 m thick outcrops of carbonate rocks aged between Sinemurian and Toarcian. This study presents the evaluation of the hydrocarbon generation potential of the Pliensbachian . lower Toarcian of the Peniche section; which includes the Vale das Fontes Formation, Lemede Formation and Cabo Carvoeiro Formation (CC1 and CC2 members) based on 233 rock samples analyzed for total organic carbon (TOC), Rock-Eval pyrolysis and bio markers. Available data of oxygen and carbon stable isotopes were also used in the paleoenvironmental interpretation. Marls and limestones with the bituminous facies (Mlbf) of the Vale das Fontes Formation, present the highest TOC values, up to 14.95%, corresponding to the ibex (upper part), davoei and margaritatus ammonites zones and part of the NJ4a and NJ4b nanno fossils bio zones (Pliensbachian). In thermal immature sections (T max about 430 deg C), this member also shows high S{sub 2} values (10 to 50 mgHC/g rock) and Hydrogen index (HI: 200 to 555 mgHC/g TOC). The correlation between HI x OI shows that type II kerogen is predominant in the portion of the section where TOC values are higher. The good positive correlation between TOC values and the bio markers ratio P/nC17 and sterane (C{sub 27}/C{sub 29}) throughout the Mlbf Member suggests a gradual increase of anoxia and higher contribution of algae in relation to terrestrial organic matter. Usually {delta}{sup 18}O variations observed in the basins of the Iberian Peninsula have been explained by temperature changes. This work proposes an alternative interpretation, by correlating {delta}{sup 18}O alterations with data on bio markers to indicate salinity variations. Thus, the presence of gammacerane in the marls and limestones with Uptonia and Pentacrinus (Mlup) and lumpy marls and limestones (Lml), associated to the increase of {delta}{sup 18}O values would indicate an environment with salinity above normal levels. In addition to this, the increase of moretanes rates towards the maximum flooding (MF) interval - which is located in the {delta}{sup 13}C positive excursion in the upper part of the Mlbf Member - margaritatus ammonites zone and NJ4b nanno fossil bio zone - associated with the absence of gammacerane, suggests gradual salinity reduction. The presence of gammaceranes at the uppermost part of the Mlbf Member, with the moretanes rate reduction and the increase of Ts/Tm values seems to indicate a new cycle of increasing salinity.

    The isolated regions of the Amazon present difficulties for integration with the electrical system which is creating some economic problems due to the consequent costs of electric generation of subsidies as a function of the fossil fuel use as oils diesel and fuel. A viable option is the use of Natural Gas - NG that is Also available in the region. Its modal of transport possible in the Region North they are for gas-lines or barges. The Compressed Natural Gas transport is distinguished that - CNG for barges was still not tested operationally in Brazil. Soon, to develop a Preliminary Study of Viability Technician - Economic - SVTE for the implantation of fluvial transport of CNG between the cities of Coari and Manaus is basic, therefore it is created strategical alternative for the electric generation in this region. The electric sector, the characteristics of the NG and the transport in this region had been analyzed to support to the work. The gas line and the fluvial transport of CNG for barges in this region are not conflicting, and they in a complementary form can act. The SVTE presented a Liquid Present Value and Internal Tax of very attractive Return justifying its implantation. (author)

    The region of Alfenas, in the state of Minas Gerais, Brazil, is predominantly constituted of Pre-Cambrian rocks with well developed alteration profiles in association with colluvial and alluvial sediments. No study to date has examined in detail its potential use in the ceramic industry. The scarce knowledge of its mineralogical and technological properties limits its value and consequently its industrial use. Until now, these clay materials have been used in a rudimental manner, in small scale in the fabrication of red tiles. The present study aimed at analyzing these clays mineralogically (X-ray diffraction), chemically (major and minor elements by X-ray fluorescence and organic carbon analysis) and technologically (pressing granulometric distribution; mechanical resistance; water absorption, apparent porosity; linear firing shrinkage; color of firing and others) in order to better understand the raw material and develop adequate technological applications. The best results of ceramic properties were the samples with higher organic content (more plastic clays) and higher values of Al{sub 2}O{sub 3} (kaolinite and gibbsite) and Fe{sub 2}O{sub 3} as well lower SiO{sub 2} content and finer grain size which contribute to a better sintering.

    is study was conducted in an area of 14 km in length oriented in the NNE direction by 7.3 km wide, covering the totality of the Serra do Carambei Granite and adjacent units. Located in the northern region of the Alagados dam, Parana State, this granite contains relatively high concentrations of K, eU and eTh, known since the 1970s through airborne and terrestrial gamma-ray spectrometry surveys. Recent radiochemical tests conducted on 61 samples of geological materials such as rocks (17 samples) and material of the weathering mantle and alluvial deposits (44 samples), confirmed the occurrence of radioactive anomalies in this granite, especially in thorium and uranium. The contents of K, eU and eTh obtained in gamma-ray spectrometry survey and radiochemical tests, converted to annual radiation dose (ARD), allowed to evaluate the intensity of natural radiation, whose levels relatively high in certain regions of the study area, can offer hazard to the local populations. The analysis and interpretation of data, as well the preparation of contour maps of K, eU and eTh were fundamental to understand the behavior and mobility of radionuclides in different environmental compartments of the area.

    The wind energy is an abundant source of renewable energy, clean and available almost everywhere. For its use, studies are needed to adequately describe its intensity for statistical methods and design for wind turbines. The objective is to structure the mathematical methods used to conduct a general description of the wind, to establish a description of the wind regime using the parameters described using the Weibull function and the analytical model of power from a wind turbine, as well as applications of these methods show. This work was developed at Rural Empowerment Lab of FCA/UNESP in Botucatu-SP. For the application of methods were utilized measurements of wind speed and direction, between 2004 and 2005, obtained by anemometer RM Young Wind Monitor-Campbell. As a result, they estimated the wind behavior and distribution of wind in the region, with 78 kWh of energy production, relatively low potential to supply a small house. Moreover, this energy could possibly be applied in ambient illumination, power supply for electric fences and irrigation of vegetables. (author)

    This study examines the characteristics of the water from the upper Tiete, as an input in the form of drinking water produced in eight stations, water treatment plant (WTP), an input for hydropower generation and wastewater generated by different anthropogenic activities. The most important problem of this basin is the wastewater that is released in the Pinheiros river and due to the deficit of 32.41 m3/s (2008) in the treatment of sewage in the metropolitan region of Sao Paulo ('RMSP') which produces one pollutant load of 920 thousand kilograms of BOD per day. The Pinheiros river's flow during the floods and drought has the same destination, the Billings reservoir. However, the legislation for floods and drought periods are different. The first case - floods occurs by the action of full control of the metropolitan region and is supported by the Joint Resolution of Secretaries of State of Sao Paulo (SEE-SMA-SRHSO on 13/03/96) that allows the pumping of water in the following emergencies: (1) estimates of flow of the Tiete river at the point of its confluence with the river Pinheiros, above 160 m3/ s; (2) raised level above 30 cm water level at the confluence with the river Pinheiros. The second case - drought, the Metropolitan Company for Water and Energy (EMAE) Project proposed flotation of the Secretary of State for the Environment (SMA, 2004) to treat 10 m3/ s water originating channel Pinheiros (set/2007 the set / 2008) by means of flotation technology in flow. Using information based on Environmental Sanitation Great Sao Paulo (SANEGRAN) and data from the operation of the prototype flotation system Pinheiros-Billings (Project QAPB), concluded that the environmental impact of the reservoir Billings for the load of pollutants (mass per second) pumped after the flotation of the Pinheiros river water was always lower than that observed in the flood control operation. The treatment presented by flotation removal of 91% for total phosphorus, 90% for E. coli, 53% for organic matter and 14% for ammonia nitrogen. There was an increase of 34% for oxygen and a decrease of 46% in turbidity. The analysis of the technical operation of the lift system Tiete-Billings, held in the AHP-Analytic Hierarchy Process, showed that 65.62% of the water entering the reservoir Billings can be used to generate electricity, while 34.38% this water can be used to supply the 'RMSP'. The feasibility study compared the economic cost of the flotation process with the cost of input of water from other sources and concluded that the cost of the flotation of the waters of the Pinheiros river to serve the supply of the metropolitan region is economically viable.

    In this work were prepared nanocomposites of polypropylene and organophilic montmorillonite Cloisite 20A with concentrations of 1.5%, 2.5%, 5.0% and 7.5% clay and graft polypropylene with maleic anhydride as compatibilizer. The mixture was made in the melt state using a twin screw extruder. The materials were characterized by x-ray diffraction, infrared spectroscopy with Fourier transform and analysis of water vapor permeation. The results of x-ray diffraction and infrared spectroscopy indicates the formation of nanocomposites with structures probably exfoliate and / or intercalated for concentrations of 1.5% and 2.5% clay, and provided a marked decrease in the water permeability, corroborating with other analysis.

    The natural radionuclides from radioactive series of {sup 238}U, {sup 235}U and {sup 232}Th have been applied as tracers in environmental studies for understanding the dynamics that occur in both marine and terrestrial environment, as for example, in research of oceanic processes and management of the coastal region. In the marine environment, these radionuclides can be used to estimate biogeochemical fluxes of marine particles and nutrients that occur in the water column as well as in the sediment. Several research works applied the distribution and the respective disequilibrium degree of natural radionuclides in the environment, including geochronological models for obtaining historical information on samples of certain sediment profile. In this study we performed a radiochemical characterization of the distribution of {sup 226}Ra, {sup 228}Ra and {sup 210}Pb from a sedimentary column called 1B (248 cm long) collected in the Admiralty Bay, Antarctic Peninsula region. The methodology used included the acid leaching of sediment samples followed by the radiochemical sequential separation of {sup 226}Ra and {sup 228}Ra by co-precipitation with Ba(Ra)SO{sub 4} and {sup 210}Pb by co-precipitation with PbCrO{sub 4}. All measurements were carried out by counting of gross alpha and gross beta measures in a low background gas flow proportional detector. The activity concentrations of {sup 226}Ra and {sup 210}Pb were used to estimate the unsupported {sup 210}Pb activities present in sediment profile 1 B. Based on unsupported {sup 210}Pb data and the application of the CIC model (Constant Initial Concentration), it was possible to determine the sedimentation rate of 0.59 ± 0.05 cm /year. (author)

    Electricity consumption forecasts for the rural economy in the region comprising the Piracicaba, Capivari and Jundiai river basins are carried out in this paper up to 2025. The structural decomposition method was used in the forecasts; the variables of this method are the total energy intensity, the share of the rural economy in the local GDP, the GDP itself and the market shares of the main energy carriers consumed in that economy. It is a very flexible methodology, which easily allows associations among alternative scenarios for the local economy development and stat-wise, or nation-wise scenarios. As no complete information on energy consumption are available on a municipality-wise level, the forecasts are limited to electricity consumption, for which all the necessary input data for the adopted forecasting method were obtained. An example of aggregation of municipalities with similar characteristics in the region (economic growth) is also presented. Such type of aggregation is important to project state-wise forecasts to municipalities in the state. (author)

    Nowadays Brazil has many isolated communities. This isolation occurs mainly due to territorial conditions. Besides this aspect, the lack of structure produces another isolation, much more harmful, the social one. To promote social inclusion and sustainable development, some requirements are essential. Amongst all of them, the provision of electricity is the most prominent. This study aimed to provide electricity to an isolated community in the Jalapao region, Mateiros city, in the state of Tocantins. It was installed a hybrid aeolian-photovoltaic system, with capacity to produce 9676.80 kWh per year. This electricity system aims to improve the production process, so it was installed at the local community workshop. The results indicate that the system can be sustainable if the community makes use of the electricity generation, using it in the production process. (author)

    This work shows the results of a monitoring carried out in an area of about 21 km{sup 2}, Dobrada Municipality, central west region of the state of Sao Paulo (Brazil), where the impacts in ground water and surface water were evaluated by the infiltration and percolation of vinasse and water used for washing cane sugar, through accumulation ponds and decantation reservoirs, respectively, in areas of Bauru Aquifer (Cretaceous). The Bauru Aquifer, free and porous, occurs in a extended area of 104.000 km{sup 2} in Sao Paulo State, as a major exploitable aquifer (more than 15.000 wells), used for domestic and industrial water supplies. For the groundwater, the following measures were found in analyses exceeding drinking water standards (WHO; CONAMA/Brazil and Sao Paulo State): manganese (0,03 to 3,5 mg/l), iron (0.45 to 34 mg/l), aluminum (1 to 52 mg/l) and phosphate (0,03 to 0.38 mg/l). For superficial water, the following measures exceeded drinking water standards: total iron (3 mg/l) and phosphate (0,035 mg/l). The main purpose of this research is to improve the field methodology to characterize the impacts of vinasse and washing water of cane sugar infiltration/percolation., detaching the relationship between ground and surface water, with the major aim to supply the legislation to protect drinking water resources.

    A major concern with leaking petroleum is the environmental contamination by the toxic and low water-soluble components such as benzene, toluene, and xylenes (BTX). These hydrocarbons have relatively high pollution potential because of their significant toxicity. The objective of this study was to evaluate the contamination of seawater by the main pollutants of the output and transport of petroleum, such as benzene, toluene, and xylene, and their removal by the exposure to the ionizing radiation. The studied region was Ubatuba region, SP, between 23 deg 26'S and 23 deg 46'S of latitude and 45 deg 02'W and 45 deg 11'W of longitude, area of carry and output of petroleum, and samples were collected from November, 2003 to July, 2005. For BTX in seawater analysis, the Purge and Trap concentrator with FIDGC detector showed significantly higher sensibility than Head Space concentrator with MSGC detector. The minimal detected limits (MDL) obtained at FIDGC were of 0.50 {mu}g/L for benzene, 0.70 {mu}g/L for toluene, and 1.54 {mu}g/L for xylene, and the obtained experimental variability was 15%. While the concentrator type Headspace system with MS detector showed higher MLD, about of 9.30 mg/L for benzene, 8.50 mg/L for toluene, and 9.80 mg/L for xylene, and 10% of experimental variability. In the studied area the benzene concentration varied from 1.0 {mu}g/L to 2.0 {mu}g/L, the concentration of toluene varied from < 0.70 {mu}g/L to 3.24 {mu}g/L and the maximum value of xylene observed was of 2.92 {mu}g/L. The seawater samples contaminated with BTX standard and exposed to ionizing radiation using a source of {sup 60}Co, presented a removal from 10% to 40% of benzene at 20 kGy absorbed doses and concentration of 35.1 mg/L and 70.2 mg/L, respectively; from 20% to 60% of toluene removal with 15 kGy absorbed dose and from 20% to 80% of xylene with 15 kGy absorbed dose in similar concentrations.

    Geophysical measurements were carried out in the Western Margin of the Antarctic Peninsula and Bransfield Strait by the Brazilian Antarctic Program during the summers of 1987 and 1988. The present work, using a continued seismic multi channel and magnetometry data profile crossing the area, intends to present a two-dimensional model of the interface sediment/basement and contribute to the understanding of the complex geology verified in the studying area. By this model, the main provinces of the are (Deep Ocean, South Shetland Trench, Accretionary Prism, Volcanic Arc South Shetland Islands and Bransfield Basin) could be determined. The seismic and magnetic measurements information when superposed can attribute more consistencies to the interpreted basement; although each method has its particular resolution. This way, when the seismic interpretation was not possible due to complex structures disposition, magnetic measurements could offer good estimation about basement depth. The fit between both methods (seismic and magnetic measurements) was reasonable both on the oceanic basin and in the region of Bransfield Strait. The magnetometry, as as well seismic, was sensible to the dip of Drake Plate at South Shetland Trench and the Intrusive occurrence at Bransfield Basin axis. (author)

    Supracrustal rocks of the Santa Terezinha de Goias region, Central Brazil, presumably represent a southern extension of the Mara Rosa magmatic arc tectonically juxtaposed to Archean terrains and consist of a meta volcanic unit and a meta sedimentary unit. The aim of the paper is to present and discuss the first U-Pb and Sm-Nd data of rocks belonging to both units of that region. U-Pb data of zircons from a felsic meta volcanic rock inter layered with chlorite-rich schists (metandesites?) yield a concordant age of of 660 My, while the Sm-Nd model age of a variety of chlorite-schists indicate a juvenile age between 1.1 and 1.3 Ga. These data indicate that the meta volcanic rocks are Neo proterozoic in age and may be correlated with rocks of the Mara Rosa magmatic arc. On the other hand, the prevailing provenance of rocks belonging to the meta sedimentary unit indicate a Paleoproterozoic, or older, source. Thus, the deposition of both units are explained by means of the erosion of source-areas of variable age. (author)

    In the area of Paripe, in the suburb of Salvador, Bahia, the distribution of electric power of the Company of Electricity of the State of Bahia (COELBA) is facing serious problems with the industrial pollution. That pollution affects the whole distribution net, causing fortuitous lack of energy, in many cases even daily in their feeders. The problem happens due to the accumulation of material associated along the net and more precisely in the distribution insulators, generating a type of dirt, no removable for normal procedures, in the surface of that insulator and it will cause escape currents, causing the lack of energy of the whole distribution electric net. The subject presented in that paper refers to the project of Research and Development (P and D), about Atmospheric Pollution in Insulators of Distribution. The results of the research showed that the atmospheric pollution could cause problems to the population that lives close the polluted area. The purpose of that article is to present relevant data related to the distribution net of COELBA, where there are many lacks of energy and the possibility of do not respect the criterion of quality of the National Agency of Electric power (ANEEL), besides the damages caused the population.

    This paper refers to the study of the bases material of the Corumbatai Formation (Parana Basin) from a clay mine, which presents limits for its use in ceramic tiles in dry grinding process due to its hardness and, especially, the high content of organic matter in relation to the clay overlaid. The characterization of the raw material and the product was accomplished by organic carbon analysis, X-ray diffraction, optical microscopy and test-firing. Firing conditions were determined to get expanded clay, using fast firing static kiln and a continuous roller kiln, both from laboratory equipment, getting samples with variable density up to the limit of expansion, with density that can reach values lower than 0,5g.cm{sup -3} because of the formation of closed pores and an external vitreous foil which provide a high mechanical resistance to the particles.

    The municipality of Monte Alegre, located in the Amazonian State of Para, Brazil, presents scattered areas with increased levels of natural radiation due to uranium rocks. The objectives of this dissertation were: to evaluate the mortality trend among Monte Alegre residents, and to compare it with that observed in neighbor municipalities (Alenquer and Prainha) without natural radiation sources; and to determine the impact of cancer distribution either in Monte Alegre or control counties population, taking into account their estimates of cancer incidence and mortality. The dissertation was organized in two papers. The first one aimed to evaluate the mortality trend for all causes of death, cancer, and unknown causes of death occurred between 1981-2005. Analyzed data was provided by the Brazilian National Mortality Information System (SIM), being the general population of the State of Para used as reference. In the second paper, cancer mortality risks at selected sites were ascertained using standardized mortality ratios (SMR) and mortality odds ratios (MOR). Additionally, cancer mortality risk ratios of Monte Alegre and control counties were obtained towards the ratio between SMRs of selected cancer sites in both areas. Three different sources of data were used to retrieve all cancer cases in the studied area, and therefore, to estimate cancer incidence in the studied populations: the diagnosed cancer cases at the regional reference centers for oncological care settled in Santarem, Belem and Manaus; the cancer-related hospitalization authorization records obtained at the Brazilian National Health System (SUS) registries; and primary data of cancer reported by local residents at a population-based health survey conducted by our research team in 2007-2008. A declining trend for all causes of death mortality in Monte Alegre general population, as well as for the unknown causes of death, was observed along the studied time series for both gender. Cancer mortality trend in Monte Alegre and at the control counties remained stable, but the high proportion of unascertained causes of death at the mortality database does not allow a conclusive ascertainment. SMR for all causes of death in Monte Alegre was similar to that observed at the control counties, respectively, SMR=72.9, 95% CI 70,5-75,3 and SMR=75.2 , 95% CI 76,2-77,3. No excess of cancer deaths was observed in Monte Alegre or at the control populations, and cancer mortality by gender also did not reveal statistically significant differences at the different tumor sites. Despite the use of three different approaches to estimate cancer incidence in Monte Alegre and the control counties, similar patterns were observed in the studied areas. To conclude, no evidence supporting an increase of cancer deaths in Monte Alegre was observed. (author)

    Through the use of radioimmunoassay (RIA) it was determined blood serum concentration of triiodothyronine (T{sub 3}) and thyroxine (T{sub 4}) (n=78) for two different water buffalo racial groups. Blood serum was collected from young and adult animals belonging to two farms in Castanhal country, state of Para, Brazil, through the year of 1988. The serum levels of T{sub 3} and T{sub 4} were statistically correlated with climatic parameters, e.g., pluviometric precipitation, environmental temperature, humidity, light intensity variation and physiological factors such as age, breed and sex. It was identified two seasons during experiment, one season the rainfall period with high precipitation rates and the other one was considered as dry season, with low precipitation rates. The average rate of temperature and humidity have shown no significant statistic difference between the two seasons. On the other hand, it was found a significant relationship between luminosity and seasons, since when the luminosity decreases the pluviometric rates increases. (author). 51 refs, 15 figs, 15 tabs.

    The Santa Gertrudes Ceramic Polo (PCSG) is the largest national producer of ceramic tiles, located in east-central region of Sao Paulo, encompassing different cities. PCSG uses various clays as the main raw material from the Corumbatai Formation, which is inserted in the Sedimentary Basin of Parana, with more than 1.5 square kilometers. In this context, X-ray diffractograms of samples from different areas of PCSG were used for application of the cluster analysis. Aiming to group the samples in families and subsequently to seek the most representative for the complete analysis. Also, ceramic tests were made by the following methods: the green bulk density after pressing, flexural strength modulus for green. , tests were conducted after firing at 1070 °C and 1120 °C: apparent density after drying, flexural modulus; after firing: apparent density after firing, water absorption linear shrinkage sintering, apparent porosity, modulus of resistance to bending after burning. Further, from the georeferenced sample were created tables for industry in the area, to facilitate the identification of new sample by XRD. Furthermore, the 3D model of the region was developed from the interesting characteristics for ceramic use, using Micromine Mining Software, Enterprise Micromine. (author)

    The coastline between Sao Sebastiao and Ubatuba cities and the shores of Sao Sebastiao, Anchieta and Mar Virado islands (Sao Paulo State, Brazil) are crosscut by several small swarms and isolated dykes trending N55E. The main rock types range from basic to intermediate, but also a conspicuous variety of alkaline lamprophyres occur side by side with the main group. The thickness of the basic to intermediate dykes vary widely, from a few centimeters to several metres, while the lamprophyres are a few tens of centimeters thick. The objective of this thesis is the petrographic, mineralogic, petrochemical and isotopic characterization of the basic and ultrabasic dykes that occur between the Sao Sebastiao and Ubatuba cities (State of Sao Paulo), also including some occurrences from the Sao Sebastiao, Mar Virado and Anchieta islands and from the Bairro Alto region (Folha de Natividade da Serra).

    This study was focused in performing a gamma radiation survey and measurements of radon concentration in soils from the Piquiri Syenite Massif, an intrusion located at central area of the Rio Grande do Sul State. This intrusion has alkaline affiliation with high concentrations of uranium in accessory minerals as zircon, sphene, apatite, and others. The gamma radiation measurements were made considering a grid with squares about 2 km side each, using the gamma spectrometer RS-125, obtaining counts per second (cps), dose rate (DR) and concentrations of K, eU and eTh. Moreover, measurements of {sup 220}Rn and {sup 222}Rn in soil were made using the AlphaGUARD equipment. The counts per second values obtained in this study range from 130 to 1045, the dose rate from 28.9 nSv/h to 424.6 nSv/h, the K concentration from 0.5 % to 8.3 %, the eU concentration from 0.8 ppm to 25.8 ppm, and the eTh concentration from 3.0 ppm to 99.2 ppm. The distribution of K defines with relatively precision the lithological contacts of the Piquiri Syenite Massif and between the two main facies of the intrusion (Main and Marginal Facies). The Main Facies of the syenite contains the highest concentrations of eTh, while the highest concentrations of eU were measured in the north area of this facies. The {sup 220}Rn and {sup 222}Rn concentrations range from 10 kBq/m{sup 3} to 550 kBq/m{sup 3} and from 5 kBq/m{sup 3} to 400 kBq/m{sup 3}, respectively, in the Main and Marginal Facies. The high values of radon measured in Main Facies of the Piquiri Syenite Intrusion may indicate high potential risk to the health of inhabitants in the area. (author)

    A major concern with leaking petroleum is the environmental contamination by the toxic and low water-soluble components such as benzene, toluene, and xylenes (BTX). These hydrocarbons have relatively high pollution potential because of their significant toxicity. The objective of this study was to evaluate the contamination of seawater by the main pollutants of the output and transport of petroleum, such as benzene, toluene, and xylene, and their removal by the exposure to the ionizing radiation. The studied region was Ubatuba region, SP, between 23 deg 26'S and 23 deg 46'S of latitude and 45 deg 02'W and 45 deg 11'W of longitude, area of carry and output of petroleum, and samples were collected from November, 2003 to July, 2005. For BTX in seawater analysis, the Purge and Trap concentrator with FIDGC detector showed significantly higher sensibility than Head Space concentrator with MSGC detector. The minimal detected limits (MDL) obtained at FIDGC were of 0.50 {mu}g/L for benzene, 0.70 {mu}g/L for toluene, and 1.54 {mu}g/L for xylene, and the obtained experimental variability was 15%. While the concentrator type Headspace system with MS detector showed higher MLD, about of 9.30 mg/L for benzene, 8.50 mg/L for toluene, and 9.80 mg/L for xylene, and 10% of experimental variability. In the studied area the benzene concentration varied from 1.0 {mu}g/L to 2.0 {mu}g/L, the concentration of toluene varied from < 0.70 {mu}g/L to 3.24 {mu}g/L and the maximum value of xylene observed was of 2.92 {mu}g/L. The seawater samples contaminated with BTX standard and exposed to ionizing radiation using a source of {sup 60}Co, presented a removal from 10% to 40% of benzene at 20 kGy absorbed doses and concentration of 35.1 mg/L and 70.2 mg/L, respectively; from 20% to 60% of toluene removal with 15 kGy absorbed dose and from 20% to 80% of xylene with 15 kGy absorbed dose in similar concentrations.

    Full Text Available A indústria da construção representa um dos maiores e mais activos sectores da União Europeia (UE, consumindo mais matérias-primas e energia do que qualquer outra actividade económica. Da mesma forma, os resíduos das suas actividades corespondem a uma elevada parcela dos resíduos produzidos em toda a UE. A actual legislação na UE visa criar condições para a implementação de medidas de prevenção e reciclagem de RCD. No entanto, carece de instrumentos que acelerem o desenvolvimento de um sector tão tradicional como o da construção. O presente trabalho tem por objectivo determinar indicadores que possibilitem estimar a quantidade de RCD gerados, ao nível da obra, tanto globalmente como por fluxo de resíduos. A geração de RCD foi estimada para seis sectores específicos: nova construção residencial, nova construção não residencial, demolição residencial, demolição não residencial, reabilitação residencial e reabilitação não residencial. Neste artigo, apresentam-se os resultados para a nova construção residencial. Os dados necessários ao desenvolvimento dos indicadores foram obtidos através de um levantamento exaustivo dos dados de estudos anteriores.

    With the increasing participation of the natural gas in the world-wide and national energy matrix, beyond the constant search for an alternative source of energy that has an acceptable behavior of the ambient point of view, they become each time more necessary studies to make possible the expansion of the use of this fuel in the diverse energy sectors, such as: Industrial, advertising, residential, to propagate, among others; Of these sectors, the residential one is what more it needs innovations and/or technological adaptations to exert a massive participation in the demand of the natural gas. This work has as objective to establish a methodology adjusted for analysis of the energy and economic viability of the introduction of installations for natural gas in the residential and commercial sector, as well as the implementation of a software that will more facilitate to the taking of decisions of this the confection of the plant low of the enterprise until the choice of the adjusted material for the installation of the tubing, besides showing to the viability technique - economic of the use of the natural gas for supplying all even though the energy necessities of this construction or of its joint participation with the electric energy or with the GLP. The methodology will mainly have support in first and the second law of the thermodynamics, beyond the norms Brazilian techniques that conduct this sector of the civil construction, taking in consideration the fixed and changeable costs of the energy construction of the construction and the involved ones. One expects, on the basis of the literature, that the introduction of installations for natural gas in the residential and commercial sector presents viability economic technique and, increasing with this the demand of this fuel and consequently its participation in the national energy matrix.

En este sentido, se busca el mejoramiento de la calidad de vida de los usuarios de estos sectores a través del reconocimiento de sus valores culturales y sus necesidades de espacio comunal y familiar. Dicha búsqueda contempla también la formación de organizaciones autónomas que permanezcan y actúen más allá del proceso de autoconstrucción y renovación del hábitat, creándose comunidades autogestionarias y autónomas que se orienten a la búsqueda de recursos para el logro de los proyectos de desarrollo y mejoramiento de su entorno. Por ello, es fundamental la participación y organización de las comunidades para la defensa y mejoramiento de nuestros asentamientos urbanos precarios, porque permite garantizar la calidad urbana en beneficio de todos, con el fin de lograr impactar en forma positiva, en las políticas urbanas y de fortalecer la participación y apropiación de los programas por parte de las comunidades como una forma de avanzar en la búsqueda de una sociedad equitativa, responsable y solidaria con el derecho a la vivienda y a un entorno apropiado.

    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.

There was a predominante of species with generalist feeding habits (omnivores and non-specialized insectivores, forest edge or secondary growth dwellers, and species that feed and nest in arboreal and shrub layers. Only 23 species are certain or probable residents; the presence of others is due to migration or to displacement of populational excedents coming perhaps from nearby urban parks. Although the vegetation is not exactly profuse, it is enough to be exploited by many forest species. As the city of São Paulo confines with the Atlantic Forest, this kind of urban vegetation may be important to the maintenance not only of resident populations but also of vagrant birds from the surroundings, including some rare or little known species.

    Full Text Available Os serviços residenciais terapêuticos (SRT no Brasil são considerados estratégicos e imprescindíveis no processo de desinstitucionalização de egressos de longas internações psiquiátricas que perderam vínculos sociais e familiares. No entanto, muitos são os problemas e desafios que este serviço evidencia no contexto mais amplo da atenção à saúde. Este artigo procura analisar alguns desses problemas e desafios a partir da experiência do SRT de Natal, Rio Grande do Norte, e de contribuições da literatura do campo. Propostos com base na idéia de que os encontros entre loucura e cidade são potentes no sentido da desconstrução da " lógica manicomial" , os SRT são problematizadores do modelo de atenção em saúde vigente, pois exigem a desconstrução das formas rígidas e hegemônicas de morar e cuidar. Pretende-se problematizar essa " lógica manicomial" que atravessa os limites dos manicômios concretos e se atualiza no cotidiano dos serviços substitutivos em certas práticas e na frágil articulação da rede de saúde mental. A falta de articulação efetiva entre SRT e Centro de Atenção Psicossocial (CAPS dá lugar a dispositivos biopolíticos no cotidiano através dos quais essa lógica opera. Discutimos, então, os riscos de captura por esta lógica e indicamos algumas das possibilidades de desconstrução, defendendo uma clínica que possibilite encontros potentes com a cidade e a construção de " redes de trabalho afetivo" produtoras de vida e liberdade.In Brazil, the home-based care services (HCS are considered strategic and essential in the de-institutionalization process of patients who passed years in psychiatric hospitals and lost their family and social links. However, this service faces a series of problems and challenges in the wider context of health care. This article seeks to analyze some of these problems and challenges based on the experience of the home-based care service in Natal RN and on the literature in this field. Proposed on the basis of the idea that the encounters between insanity and city are potent destructors of the " asylum logic" , these home-based care services put in question the current healthcare model, claiming to destruct the rigid and hegemonic forms of residence and care. The aim of this article is to discuss this " asylum logic" that surpasses the limits of the concrete insane asylum penetrating some daily practices of the substitute services, taking advantage of the weak articulation between the mental health services. The lack of a strong connection between the home-based care service and the psychosocial care center allows this logic to operate through day-by-day bio-political devices. Thus, we discuss the risks of this logic taking over and indicate some possibilities of avoiding this, defending a care model allowing for potent meetings with the city and for the construction of " affectionate networks" producing life and liberty.

Um estudo de caso de uma habitação em Florianópolis, SC, foi realizado por meio de simulação computacional no EnergyPlus com o arquivo climático TRY. Foram definidos 15 parâmetros utilizados no RTQ-R, variados por meio de amostragem com o Hipercubo Latino e geraram-se 500 simulações aleatórias. As variáveis dependentes são os graus-hora de resfriamento, consumo relativo com aquecimento e com refrigeração. Para a análise de sensibilidade foram utilizados os métodos dos Coeficientes de Regressão Padronizados e Coeficientes de Correlação Parcial. Foram feitas análises de variabilidade e comparação de simulações individuais. Os resultados mostraram que os parâmetros mais influentes diferem para cada variável dependente, o que dificulta a proposta de soluções de desempenho que atendam às condições de verão e inverno simultaneamente. A absortância solar e a emissividade da cobertura foram os parâmetros mais influentes em geral. O trabalho contribuiu para a identificação quantitativa dos parâmetros mais influentes no desempenho da edificação, o que pode auxiliar nos processos de otimização e na proposta de níveis de classificação de desempenho em certificações.

    Although Brazil has great potential for photovoltaics (PV), and is particularly privileged by high solar radiation levels, the role of this renewable energy source (RES) at the Brazilian market is still very small, and the current legislation of the electric sector has no incentives for grid-connected PV systems. The high costs and the paradigm that this RES is feasible for grid-connection only for developed countries are the fundamental arguments placed to justify the lack of consideration of PV energy in Brazil. The main aim of this thesis is to develop a guideline to create a reliable legislation and regulation framework for the Brazilian electrical sector towards the implementation of a widespread grid-connected PV roofs program, and to show a grid parity analysis between conventional generation and PV generation. It also demonstrates the benefits of grid-connected PV systems and it presents the bottlenecks that limit the widespread adoption of PV energy at the Brazilian electrical sector mix. The proposed mechanism to be applied in Brazil is based on the German program (Feed-in Law) and it is analyzed under different scenarios. With this study, it is possible to make an economic viability analysis of grid-connected PV in Brazil, to identify the most suitable PV roof program size for the beginning of the program, and the consequent impacts on tariffs, through the dilution of these costs for the residential energy consumer. The grid-parity analysis shows that from 2015 and 2020 it will be possible to reach grid parity for PV in some regions in Brazil. It is possible that this parity happens even before that time, according to the interest rates applied in Brazil. In this context, it is crucial to create an incentive program to promote PV energy in Brazil, even if current prices are not competitive with conventional generation prices, so that the necessary experience to develop a large scale mechanism could happen with the maximum benefits and in an orderly way when grid parity arrives.

Partimos de un panorama general sobre el espacio y la ciudad, donde refrescamos el tema de la segregación que minimiza la coincidencia de los grupos sociales en los espacios urbanos. El presente análisis destaca el pensamiento sobre el hábitat residencial, ámbito condicionante de vida y lugar de soporte y significación. Complementamos con la revisión del tema del espacio pú-blico seguro, que es articulador del hábitat residencial y, en cuanto lugar de encuentro y relaciones, debe ser defendido por sus habitantes, punto final de disertación en la presente exploración.

    Full Text Available Basado en una investigación cualitativa sobre trayectorias residenciales y movilidad cotidiana, el artículo evidencia que las redes familiares modulan los usos de la ciudad y traccionan las decisiones de localización residencial. La proximidad geográfica con la familia parece un valor a alcanzar al momento de decidir el destino de una mudanza. Se trata de una lógica residencial que prioriza no vivir juntos, pero sí cerca y la geografía de las familias parece dar cuenta de ello. Además, las redes familiares operan en la inscripción territorial porque a través de la herencia, préstamos familiares y regalos monetarios provee recursos para acceder a una vivienda en propiedad.

    2003-01-01

    Full Text Available La proliferación del discurso de la brecha digital constituye un hecho sobresaliente del debate con respecto al desarrollo de la telefonía fija residencial. Para los autores y seguidores de las tesis brechistas, la baja teledensidad se encuentra vinculada, por medio de un determinismo lineal, con la marginación social, destacando en una visión trascendente de la telefonía, la esperanza de superar los rezagos de la integración social y territorial con las tecnologías de información y las comunicaciones. En el presente estudio, la exploración de la telefonía residencial dentro del universo censal de los factores de marginación deja entrever una relación compleja sustentada en particularidades y deficiencias cruzadas. Frente a la amplitud y la variación de los factores de rezago socioterritorial en la frontera norte, la disponibilidad residencial del teléfono en varias localidades sale sobrando.

  14. Study of heat and salt transport processes in the Espinheiro Channel (Ria de Aveiro)

    Science.gov (United States)

    Vaz, Nuno Alexandre Firmino

    O principal objectivo deste trabalho consistiu no estudo da dinâmica termohalina do Canal do Espinheiro em funcao de dois forcamentos principais: mare e caudal fluvial, usando duas abordagens distintas: trabalho experimental e modelacao numerica. A propagacao da mare e o caudal fluvial do Rio Vouga sao determinantes no estabelecimento da estrutura horizontal da salinidade ao longo do canal. A estrutura termica horizontal ao longo do canal e, em grande parte, determinada pela variacao sazonal da temperatura da agua do Rio Vouga, bem como, pela variacao sazonal das condicoes meteorologicas devido a reduzida profundidade. Foi observada a formacao de fortes gradientes de salinidade (relacionados com a formacao de frentes estuarinas) numa regiao a cerca de 7-8 km da embocadura do canal, observando-se a sua migracao numa regiao de aproximadamente 1 km, dependendo do regime de mare. O balanco entre o transporte de sal de natureza advectiva e difusiva foi calculado, revelando que junto a embocadura os processos fisicos que mais contribuem para o transporte de sal sao a circulacao residual e o aprisionamento da agua em canais secundarios. Junto a foz do Rio Vouga os termos devidos a descarga fluvial e a circulacao gravitacional dominam o transporte de sal. Foi calibrado e validado um modelo numerico (Mohid, em modo 2D e 3D), sendo posteriormente utilizado para estudar a hidrologia do canal. Foi concedida particular atencao ao estudo da hidrologia em condicoes extremas de caudal fluvial e de mare. Os resultados da modelacao numerica permitiram numa primeira fase avaliar o bom desempenho do Mohid na reproducao dos escoamentos barotropicos na Ria de Aveiro, bem como na evolucao temporal das propriedades termohalinas da agua. Sob condicoes de caudal fluvial reduzido, a dinâmica do canal e essencialmente dominada pela mare. Com o aumento do caudal fluvial, a influencia da agua doce estende-se para jusante, estratificando a coluna de agua. As simulacoes 3D do Canal do

    The energy transfer processes (ET) from the {sup 4}I{sub 13/2}; {sup 4}I{sub 11/2} levels of Er{sup 3+} and {sup 5}I{sub 6} levels of Ho{sup 3+} ions in LiYF{sub 4} (YLF) crystal and ZBLAN glass to Nd{sup 3+}, Tb{sup 3+} or Eu{sup 3+} deactivators ions were studied. The micro parameters of these energy transfer processes were determined using the overlap integral method, and showed that Eu{sup 3+} ion is the best deactivator of the first excited state of the Ho{sup 3+} in YLF, and Nd{sup 3+} is the best deactivator of the Er{sup 3+} in YLF and ZBLAN materials. The 1.5 and 2.7{mu}m emissions of Er{sup 3+} and 2.1 and 2.9{mu}m fluorescence of Ho{sup 3+} were measured using short laser pulses excitations from a tunable OPO pumped 2w-Nd:YAG laser system. We proposed a criterion for discriminating the energy transfer processes assisted by excitation migration (diffusion or hopping) among donors. It was observed that diffusion model describes the ET process from the second excited state of the donor (Er{sup 3+} or Ho{sup 3+}) independently of the C{sub D-D}/C{sub D-A} ratio, while the hopping model can describe the ET process involving the first excited state of donor. We proposed a modification of the hopping model in order to describe the experimental results for systems having C{sub D-D}/C{sub D-A} {>=} 10. Using the ET parameters, we determined that the best systems for laser action at 3{mu}m are the Ho:Eu:YLF, Ho:Nd:YLF and Er:Nd:YLF systems. On the other hand, we found that Er{sup 3+} doped (1.5 mol%) ZBLAN glasses, single and co-doped with Nd{sup 3+}, Tb{sup 3+} or Eu{sup 3+}, do not show potential for laser action at 2.8{mu}m. The up-conversion processes were studied in Er:YLF systems as a function of the Er{sup 3+} concentration, and the excited state absorption (ESA) and up conversion by energy transfer (ETU) processes were discriminated using a time resolved fluorescence decays. It was observed that 980 nm is the most convenient wavelength for pumping the Er:YLF system for quasi cw laser operation at 2.8{mu}m. The pump-probe technique was used to investigate the lifetime effects in Er:YLF system showing that the excitation migration contribution to the lifetime of the first and second excited states of Er{sup 3+} decrease with the laser pump power increasing. Using the ET experimental rates determined for the best systems previously chosen based on the R{sub N} parameter as the input in the rate equation system numeric solved by Runge-Kutta (4{sup th} order), it was possible to evaluate the population density inversion for 2.8{mu}m (Er{sup 3+}) and 2.9{mu}m (Ho{sup 3+}) as a function of the pumping rate, activators and deactivators concentrations. The best concentration found for Er:YLF system was 20 mol%. The best concentrations in the case of Er:Nd:YLF system are 4 mol% of Er{sup 3+} and 1.5 mol% of Nd{sup 3+}. A frequency increasing from 14Hz to 391 Hz has been estimated as the maximum operation frequency for the Er(20 mol%):YLF and Er(4 mol%):Nd(1.5 mol%):YLF, respectively, based on the measured {sup 4}I{sub 13/2} excited state lifetime of Er{sup 3+}. The best concentrations of Ho{sup 3+} and deactivators found for the Ho-laser in YLF are Ho(0.6 mol%):Nd(1.5 mol%) and Ho(3 mol%):Eu(1.2 mol%). The Ho(3 mol%):Eu(1.2 mol%) system showed a population density inversion 2.4 times bigger than the one verified in Ho(0.6 mol%):Nd(1.5 mol%) system. (author)

    Full Text Available Este artículo aborda la reintegración de un adolescente a su madre y las razones que dieron lugar a múltiples medidas de atención residencial. El estudio se hizo desde el enfoque sistémico y la teoría de las redes sociales. Los instrumentos fueron red-mapas, entrevistas y análisis de documentos. El análisis de la información se basó en el enfoque constructivo interpretativo que resultó en dos áreas de significado: “La repetición de abandono y las dificultades en el proceso de reintegración familiar” y “no contaba con nadie” frente a “tenía mucha gente, pero de nada ayudaba”. Llegamos a la conclusión de que varias medidas de atención residencial adolescente se deben a la fragilidad de sus lazos familiares y la falta de un trabajo integrado con las redes sociales.

    Full Text Available Entre las medidas más relevantes para frenar el calentamiento global se encuentra el control de las denominadas emisiones difusas, siendo las emisiones derivadas de las fuentes móviles una de las componentes más importantes dentro de tales emisiones. En el presente trabajo se han estudiado las emisiones difusas en el marco del diseño urbanístico y se han desarrollado métodos para el cálculo de las emisiones derivadas del tráfico rodado en función de parámetros de diseño urbanístico; como los usos del suelo, la longitud de viales o la edificabilidad, obteniendo así expresiones no lineales que permiten predecir los niveles de emisiones para diferentes usos. Los resultados muestran coeficientes de determinación de 0,644 para el uso residencial, 0,591 para el uso industrial, 0,592 para el uso terciario y 0,591 para los equipamientos, cifras de las que se deduce una mayor capacidad explicativa del modelo predictivo de las emisiones para el uso residencial.

  13. Juntos pero no revueltos: Procesos de integración social en fronteras residenciales entre hogares de distinto nivel socioeconómico

    Directory of Open Access Journals (Sweden)

    Alejandra Rasse

    2015-01-01

    Full Text Available Las secuelas negativas de la segregación residencial de los hogares más pobres han sido ampliamente descritas, pero poco se sabe sobre las consecuencias de la proximidad entre hogares de distinto estrato socioeconómico. Los estudios existentes no llegan a consenso: la proximidad es interpretada por algunos como una expresión distinta de exclusión; otros piensan que esta cercanía permite mejorar las oportunidades de integración de los hogares de menores ingresos. Este estudio busca aportar a esa discusión retrotrayéndose a las dinámicas subyacentes a las consecuencias de la proximidad residencial en términos de inclusión y cohesión social. Por medio de un estudio cualitativo de casos, se concluye que la proximidad se asocia a dinámicas de inclusión social de los vecinos de menores ingresos y al reforzamiento de la cohesión social, al hacer evidentes elementos transversales de pertenencia a un proyecto social común. Esto se debilita cuando la distancia social es demasiado grande, y en casos con historial de violencia.

    The housing estates in Bratislava saturated the housing needs of a large number of inhabitants who come after World War II to the city. Design of public spaces often did not have priority in the process of designing. The solutions for mentioned exterior spaces had been planned after blocks of flat realization, but many of them are not realized to this day. The article analyzes the example of the unrealized public spaces in existing housing estates Devinska Nova Ves and Petržalka (city districts of Bratislava) and offer practical solutions in relation to residencialization method. Residencialization of missing public places is an effective method of adding identities to settlements. It improves the quality of residential environment and public spaces. The main aim is to create better conditions for social activities in public areas, which are missing on the present. The research will be focused on the examination of the urban, cultural and construction potential of the existing residential enviroment in Bratislava. The main aim of residentialization is not only to enhance the quality of spatial and building structures in the selected residential area and maintain long-term sustainability in the pertinent programme area, but mainly to improve the quality of living for the residents. The outputs of the project are proposals and practical procedures developed with regard to planning documents for local municipal authorities and regional organizations. The solutions will have a positive impact on the enhancement of the quality of public spaces, attractive social activities and of a conceptual link - residentialization.

    Full Text Available Los análisis sobre la ciudad insegura han postulado teorías explicativas centradas en cierto tipo de determinantes (desempleo y pobreza; marginalidad juvenil; desarticulación comunitaria; diseño espacial; y déficit de espacio público, y han destacado que las políticas públicas preventivas más importantes se refieren al crecimiento económico y empleo, al desarrollo comunitario, y las intervenciones locales y recuperación de espacios degradados. Este artículo destaca la importancia del problema de la segregación residencial de los sectores de menores recursos como un mecanismo importante de la exposición al delito en las ciudades y que debe formar parte central de una agenda de recuperación físico-social de los barrios excluidos. Para esto se analiza, por una parte, la asociación entre un índice de segregación residencial socio-económica de nuestras ciudades principales, a partir de datos del censo 2002 de escala de distritos, con los niveles de denuncia de delitos de mayor connotación social a escala de ciudades. En segundo término, en base a datos del observatorio de satisfacción residencial del ministerio de vivienda y urbanismo, estudiamos la percepción de inseguridad al peligro en el espacio público de grupos contrastantes en cuanto a edad, específicamente, jóvenes y adultos mayoresThe literature on the causes of urban insecurity propose several explanations (unemployment and poverty, marginalization of youth, community disintegration, urban design, and lack of public space and suggest that the most important preventative policies are economic growth and employment, community development, and local interventions in degraded spaces.

    Full Text Available This paper intents to contribute to a critical analysis on the production of low-income housing by the private sector in medium-sized cities in Brazil, between 1999 and 2008, examining their effects on urban space. Discusses the role of municipalities, post-1988 Brazilian Federal Constitution, with emphasis on the Programa de Arrendamento Residencial (PAR, established in 1999 by the Federal Government, and taking as a case study Presidente Prudente, a city located west of Sao Paulo State. Its focus is to discuss the relationship between the urban and housing policies and enterprises implementation by the private initiative and funded by the Caixa Economica Federal, through the PAR, its mechanisms and effects on the production of urban space. It is evident in the urban policy of this city that the absence of specific guidelines towards housing policy leads to a direct action of private capital, which contributes to the production of urban segregation and exclusion.

    Full Text Available Los espacios periurbanos del área metropolitana de Santiago son el escenario de importantes transformaciones sociales, demográficas y territoriales, que se manifiestan en nuevas modalidades de ocupación del territorio rural. En este proceso de expansión de la metrópoli la función residencial es el principal motor de cambio. Tanto las viviendas en parcelas de agrado, individuales o agrupadas en condominio, como las soluciones habitacionales de carácter social, impulsadas por el Estado, contribuyen a dibujar la forma en que los asentamientos humanos se establecen en el territorio. A partir del estudio de las comunas de Pirque, Calera de Tango, Padre Hurtado y Lampa, se efectúa una lectura del nuevo diseño socio espacial que generan dichas agrupaciones residenciales.

  1. LA DIVERSIFICACIÓN Y CONSOLIDACIÓN DE LOS SERVICIOS SOCIALES PARA LAS PERSONAS MAYORES EN ESPAÑAY SUECIA

    Directory of Open Access Journals (Sweden)

    María Dolores Puga González

    2011-01-01

    Full Text Available La información sobre los servicios públicos para las personas mayores a menudo se limita a la atención residencial y a la ayuda a domicilio. Sin embargo, estos servicios básicos son en muchos países complementados o sustituidos por otros servicios de menor envergadura, como el transporte, comidas a domicilio, teleasistencia y centros de día. Esta diversificación partió de un racionamiento de los servicios para lograr una asignación más racional de los recursos y, si se podía, un menor gasto. En este trabajo se utilizan diversos datos sobre estos servicios en España y Suecia. Cuando se consideran todos los cuidados, la cobertura de atención es mucho mayor que si sólo se contemplan los servicios básicos. Esto indica una mayor consolidación de los mismos. Los datos sugieren mayor focalización en Suecia, y prestaciones fragmentadas en España, donde parece que los usuarios alcanzan lo disponible, con poca diferenciación entre sus necesidades. Cuando las tasas de cobertura son superiores, como en Suecia, hay mayor solapamiento entre el cuidado familiar y los servicios públicos. Con tasas más bajas, como en España, los cuidados familiares y los servicios públicos son sustitutos unos de otros. Se sugiere que una mayor diversidad de servicios, básicos y secundarios, puede adaptarse mejor y de manera más eficiente a las diversas necesidades de las personas mayores que la elección entre ningún servicio, ayuda domiciliaria o atención residencial. Aunque estos servicios secundarios también puedan ser utilizados como un sustituto de bajo coste, e inferior calidad, en la atención.

    Full Text Available El acelerado crecimiento urbano ha provocado, entre otras cosas, el incremento de los asentamientos informales en las periferias latinoamericanas y el aumento de la desigualdad urbana. Una desigualdad creciente que provoca, en muchos casos, una segregación residencial socioeconómica que implica un distanciamiento de los distintos grupos de población que conforman una comunidad. Un fenómeno que se encuentra en aumento en el contexto latinoamericano. En ciudades de tamaño considerable, las experiencias obtenidas en intervenciones de integración y mejoramiento de estos sectores suelen ser enriquecedoras. Sin embargo, ¿qué estrategias podrían ser aplicadas en ciudades intermedias con bajas posibilidades de financiación y presupuestos limitados? Este artículo indaga en el desarrollo de estos procesos en la ciudad de Ibagué-Colombia e intenta encontrar algunas estrategias aplicables desde el diseño de un proyecto de cooperación universitaria. En un inicio establece una aproximación a los aspectos que han fomentado la reproducción de los asentamientos informales en el contexto y sus posibles relaciones con la presencia de segregación residencial socio-económica. Posteriormente, estudia el proceso evolutivo de los asentamientos informales en Ibagué y toma al barrio Las Delicias como laboratorio de experimentación. Finalmente, se plantea un proyecto de cooperación para el mejoramiento barrial de estos sectores.

    Full Text Available Este documento tiene como objetivo discutir el surgimiento de una nueva tipología residencial que se ha extendido en el sur de Natal / RN, los condominios llamado Club. Su principal característica es la apelación a los artículos de ocio más diversos, que son utilizados por los empresarios urbanos como una forma de crear un nuevo estilo de vida y un nuevo producto que se vende. La base teórica de este trabajo se basa en el enfoque heterodoxo de la coordinación espacial realizada por Pedro Abramo. Esta perspectiva considera el espacio urbano como un conjunto de inventario de viviendas que son ofrecidas por los empresarios urbanos. En general, el orden urbano y el ambiente residencial es incierto, porque sufren cambios derivados de la aparición de las innovaciones de espacio causadas por empresarios urbanos en busca de beneficios extraordinarios. En el caso de la zona sur de Natal, la construcción de carreteras principales que conectan esta zona de la ciudad al vecino municipio de Parnamirim, que ha sido el blanco de la abundancia del mercado inmobiliario de Natal. El ciclo de vida de los inventarios residenciales de la Zona Sur de Natal ha cambiado con el tiempo, desde el principio de la vivienda en grandes alojamientos para la producción de proyectos verticais. En la actualidad, un fenómeno nuevo que se plantea es la propagación de una nueva clasificación, los condominios club. Al ser un caso reciente en que los proyectos se encuentran todavía en fase de lanzamiento o de la construcción, el estudio se llevará a cabo mediante el análisis de marketing utilizadas por los empresarios urbanos para atraer a los consumidores a través de panfletos y folletos.

    Full Text Available Current energy policies focus on retrofitting to achieve Horizon 2020 aims, especially concerning the residential stock constructed before the first thermal regulations. According to this, improving energy efficiency and interior comfort conditions in buildings must be supported by the knowledge of its real energy performance. Due to uncertainty and the lack of information on the current energy performance of housing and its real operational conditions, discrepancies between the results obtained and the measured data arise. Housing monitoring under real occupational conditions become essential for a better understanding of environmental behavior of residential building stock. Our aim is to show the calibration process, based on monitoring data obtained from a group of dwellings of national heritage interest built in the 1950s in Seville (a Mediterranean climate city. Calibration allows simulation results to approximate to current environmental conditions, aiming to predict and optimize the potential for subsequent environmental and energy implementation.Las actuales políticas energéticas europeas proponen la rehabilitación para poder alcanzar los objetivos del Horizonte 2020, especialmente del parque residencial construido antes de las primeras normativas térmicas, debiendo cimentarse la mejora en eficiencia energética y confort en el conocimiento de su comportamiento energético real.

Las conclusiones dan cuenta de cómo en la Ciudad de México se notan rasgos del modelo tradicional de segregación, como la persistencia de las élites en ciertos espacios, y cómo los estratos proletarios y las clases medias han tenido una marcada dispersión, junto a la localización periférica de los grupos pobres, más en sintonía con las propuestas del actual modelo de dispersión y fragmentación del espacio urbano.The aim of this analysis is to establish a socio-demographic differentiation for Mexico City using a methodology that presents two main contributions: first, it applies ageo-demographic typology based on life styles or socioeconomic levels taken from geo-marketing databases; and second, it uses highly disaggregated census information at block levels that has only been applied in very few studies. Six clusters and several segregation indices were calculated. Conclusions show that Mexico City has features of the traditional residential segregation model with elite groups highly concentrated in specific zone, while other socio-demographic groups such as the middle and working classes present a marked dispersion in urban space, more in accordance

    Full Text Available This paper examines some of the meanings that are sometimes neglected under the generic term of neorurality. From our point of view, moving one’s home from town to countryside is not solely a change of house, but a life venture, bringing together social representations of the rural and the urban, of country life and the urban lifestyle. In the case of people who have moved from Pamplona (county town of Navarre, a northern region of Spain to any rural area of Navarre, these representations, along with the broad heterogeneity of underlying reasons and expectations for the future, have shaped three different types of neo-rurality. They represent, somehow, three ways of constructing differing rural spaces (and ruralities. The paper analyses these types of neo-ruralities and the significance of the move for the migrants in the context of Navarre. To do this, we analyse the discourse expressed in diverse indepth interviews conducted with people who have identified themselves as urban-to-rural migrants.

    El presente artículo tiene como objetivo indagar en los significados que se esconden tras el concepto paraguas de neorruralidad. El cambio residencial de la ciudad al campo es concebido aquí no sólo como un cambio de vivienda, sino como una apuesta vital en la que confluyen una serie de representaciones sociales sobre lo rural y lo urbano, sobre la vida en el pueblo y la vida en la ciudad. En el caso de quienes abandonaron Pamplona e instalaron su hogar en un pueblo de Navarra, estas representaciones y la heterogeneidad de expectativas de futuro subyacentes conforman tres tipos de neorruralidad diferentes que representan, a su vez, distintos modos de construir espacios rurales (y ruralidades diferenciados, más o menos divergentes. A través del discurso expresado en una serie de entrevistas en profundidad, realizadas a personas que se autoidentificaban como migrantes urbano-rurales, exploramos estos tres tipos de neorruralidad y el sentido

    Full Text Available El presente artículo estudia el fenómeno de las urbanizaciones cerradas en el distrito de San Rafael de Escazú, Costa Rica. La tesis central es que las urbanizaciones cerradas producen cambios en la urbanidad mediante la introducción de transformaciones socio-espaciales manifiestas en la materialidad de las urbanizaciones cerradas, las funciones de estas y el tipo de relaciones sociales que sus residentes mantienen entre sí y con su entorno cercano. El artículo cierra sugiriendo explorar la noción de “urbanidad privada” como una forma de entender la producción de espacio promovida desde los intereses privados expresados en la construcción de conjuntos inmobiliarios cerrados, de los cuales las urbanizaciones cerradas son una de sus manifestaciones más visibles. Los resultados presentados en este ensayo, son producto de la investigación titulada “Urbanizaciones cerradas en Costa Rica: transformaciones socio-espaciales en la urbanidad y segregación socio-residencial en el distrito de San Rafael de Escazú (1990-2012”. This paper examines the phenomenon of gated communities in Costa Rica, specifically in the district of San Rafael, Escazú. The central thesis is that gated communities to changes in urbanity by introducing socio-spatial transformations evident in the materiality of gated communities, the functions of these communities and the type of social relations that its residents have with one another and with their immediate environment. The article suggests exploring the notion of “private urbanity” as a way to understand the production of space promoted by private interests and expressed in the construction of closed real estate developments, most visibly manifested by gated communities..

    Full Text Available ResumenEste artículo analiza la evolución de las áreas con población vulnerable y la segregación residencial del Área Urbana de Madrid (AUM entre los años 1991 y 2001. La investigación se realiza mediante el análisis de dos índices utilizados anteriormente en la medición de la desigualdad urbana y la segregación espacial (HERNÁNDEZ AJA, 2009: el índice de población analfabeta y sin estudios, y el índice de viviendas sin retrete o cuarto de aseo. En el periodo de estudio observado ambos índices experimentaron mejoras significativas en escalas de agregación espacial nacional, regional o de área urbana (INE, 2004. Sin embargo, en este trabajo se refleja que la distribución de estas mejoras a escalas municipales e inframunicipales no es homogénea: en este periodo se incrementaron los desequilibrios internos en el AUM y éstos responden a patrones espaciales diferenciados para los municipios de la corona metropolitana y el municipio central del AUM.Palabras claveVulnerabilidad urbana, segregación residencial, áreas metropolitanas, geografía urbana de la desigualdad, corona metropolitana.AbstractThis article analyzes the evolution of vulnerable areas and residential segregation in Madrid Urban Area (AUM between 1991 and 2001.

En este sentido, se pretendía modificar el tradicional modelo territorial madrileño, de expansión residencial periférica, con el objeto de evitar el declive demográfico de la capital. La perspectiva de más de diez años de gobierno municipal permite aventurar que una parte importante de los objetivos propuestos no se han cumplido y lo que es aún más grave, el problema de la vivienda se ha acentuado hasta límites insoportables. El crecimiento del parque inmobiliario residencial, hecho incontestable acaecido con el auge de la construcción de los últimos años, ha venido acompañado del incremento desorbitado de los precios y de una progresiva disminución del número de viviendas de protección en el mercado, lo que ha alejado a las capas de población de menor nivel de renta de la posibilidad de acceso a este bien tan fundamental.Since their original adoption in 1993, the operation of the Programmes of Town Planning Conduct (Spanish abbreviation «PAUs has constituted the first great political bet of the government of the Spanish Popular Party, in the attempt to place new áreas of expansión in the interior of the city centre on the marketpiace for land.

    Full Text Available Catalonia is known to be the main point of settlement of the Moroccan population in Spain. Moroccans start their presence in the decade of the 1970s, representing one of the most ancient and consolidated migratory flows. One out of three Moroccans in Spain live in Catalonia, a region that is an initial point of attraction as well as a point of reception of the residential mobility produced in Spain. In Catalonia this population is characterized in comparison with other nationalities by a greater settlement, by a strong territorial dispersion and the presence of nuclear families, or by an upper proportion of homeowners in comparison to other groups of more recent insertion. The purpose of this work is to plot a panoramic view of this settlement taking into account the territorial diffusion, the insertion in the job market and the family and residential structure from 1991 until 2006. The evolution of Moroccan population will be compared with the evolution of the whole of the foreign population.

    Cataluña destaca por ser el principal punto de asentamiento de la población marroquí en España, con una presencia inicial que se remonta a la década de los setenta, representado una de las corrientes migratorias más antiguas y consolidadas. Uno de cada tres marroquíes que residen en España se encuentra en Cataluña, actuando tanto como punto inicial de atracción como de recepción de la movilidad residencial producida en España. Esta población, en Cataluña, se caracteriza en comparación con otras nacionalidades por un mayor asentamiento, con una fuerte dispersión territorial, una mayor representación de núcleos familiares, o una proporción superior de residentes en viviendas de propiedad en comparación a otros colectivos de inserción más reciente. El propósito de este trabajo es trazar una panorámica de ese asentamiento tomando como muestra la difusión territorial, la inserción en el mercado laboral y la estructura familiar y

    Este trabalho apresenta um estudo experimental dos semicondutores organicos Ftalocianina (H2Pc), Ftalocianina de Zinco (ZnPc) e Ftalocianina de Cobre (CuPc) por tecnicas de µSR, tendo-se obtido informacao detalhada sobre a estrutura electronica dos estados de carga formados pelo muao positivo nos tres compostos, e sobre as interaccoes dinamicas a que esses estados se encontram sujeitos. Os resultados do estudo indicam que nas ftalocianias com caracter nao magneticas H2Pc e ZnPc se da a formacao de tres radicais muonicos paramagneticos distintos. A estrutura hiperfina destes radicais, referidos como estados I, II e III, foi caracterizada atraves da medida dos parametros de acoplamento hipefino em conjunto com a parameterizacao da sua dependencia com a temperatura. Uma quarta componente paramagnetica do sinal µSR foi tambem identificada, mas sobre a qual nao foi possivel retirar conclusoes definitivas quanto a sua origem. Verificou-se que os parametros de acoplamento hiperfino isotropicos dos tres estados identificados se encontram numa regiao de valores entre os 100 e os 150MHz para os estados I e II, enquanto que para o estado III esta quantidade toma valores em torno de 10 MHz. A estrutura electronica de todos os estados possui simetria axial, caracterizada por parametros dipolares de cerca de 15MHz para os estados I e II, e 20MHz para o estado III. A origem dos estados I e II foi determinada como sendo devida a adicao de muonio a uma das ligacoes duplas existentes nos aneis benzenicos da periferia das moleculas de ftalocianina recorrendo a calculos de estrutura electronica, tendo-se verificado a existencia de um acoplamento entre a interaccao hiperfina desses estados e modos vibracionais desses aneis. A problematica da localizacao do estado III tambem foi abordada, tomando-se como hipotese mais provavel uma posicao intersticial entre duas moleculas de ftalocianina.

Com base nos resultados das simulacoes efetuadas, a pluma e classificada como de larga escala e de advecao superficial, apresentando caracteristicas de uma pluma prototipica. Em condicoes de caudal moderado a elevado, a descarga estuarina e suficiente para gerar uma corrente costeira para norte sem acao do vento. Em eventos de ventos leste, a propagacao da pluma e similar ao caso sem vento, com um aumento da velocidade da corrente. Uma corrente costeira para sul e unicamente identificada sob condicoes de forte vento de oeste. Ventos de norte tendem a estender a pluma para o largo, com uma inclinacao na direcao sudoeste, enquanto ventos de sul intensificam a corrente para norte, sendo a mistura das plumas do Douro e do Minho uma consequencia possivel. A analise desta interacao apontou a contribuicao do Douro como importante na estabilizacao da WIBP e nas trocas de agua entre o oceano e as Rias Baixas. A interacao da pluma do Douro com estuarios localizados a sul da sua foz e a confirmacao in situ da recirculacao observada nos resultados numericos afiguram-se como temas relevantes para investigacoes futuras.

From each individual we extracted a strip of muscle from the region above the lateral line, in the dorsal fin base, that was divided into three equal parts, each one was submitted to one type of treatment: freeze . control group (-15oC, conservation in alcohol 70%and fixation in formaldehyde 4%. Samples were kept under those treatments for 30 days, washed and submerged in distilled water for 4 hours. Afterwards, they were dried up in air oven at 60oC for 48 hours and macerated until the obtaining of a fine powder. A significant difference was found in isotopic values of carbon and nitrogen, between the control and the samples in alcohol and formaldehyde, except for ƒÂ13C from the H. edentatus samples in formaldehyde. The carbon isotopic values of samples in alcohol were mostly enriched compared to control, whereas the samples in formaldehyde presented depleted values in relation to the control. The nitrogen isotopic values for both samples preserved in alcohol and formaldehyde were enriched when compared to the values of frozen samples, independently of used preservatives. Therefore, the isotopic correction should be accomplished according to the isotope and preservative employed for species of freshwater fish.O presente estudo investiga a composicao isotopica de ƒÂ13C e ƒÂ15N entre as amostras congeladas (controle, em alcool e em formol de Plagioscion squamosissimus e Hypophthalmus edentatus.

    Full Text Available Este artículo muestra una variedad de posibles soluciones ante las dificultades que los científicos sociales pueden encontrarse en la investigación cuantitativa con poblaciones elusivas. Estas dificultades son de dos tipos: epistemológicas y técnicas. Desde el punto de vista epistemológico, se subraya la necesidad de adaptación de la investigación a las características de la población objeto de estudio, pues la elusividad de la población no puede considerarse un obstáculo insalvable. Esta flexibilidad se muestra más constructiva, en términos de consecución de objetivos de investigación, que un posicionamiento más rígido o tradicional, más apegado a modelos preestablecidos. Desde el punto de vista técnico, se muestran las soluciones ante cada dificultad encontrada en el curso de un estudio de caso: la población turístico-residencial del destino Costa Blanca en el Levante español. Estas soluciones se demuestran, finalmente, como adecuadas al contrastar los resultados con encuestas oficiales tipo panel realizadas de forma tradicional en origen.

    Full Text Available Se propone un plan de muestreo para ciudades de tamaño mediano, que inicia con un muestreo bietápico piloto que conduce a una estimación del tamaño de muestra cuando se utiliza un estimador de razón. En el muestreo bietápico se utiliza el lado de manzana como unidad primaria de muestreo seguida de las viviendas como unidades secundarias. A partir de un marco muestral conformado por lados de manzana, se selecciona la muestra de lados de manzana para satisfacer un error de muestreo máximo del 5% con un nivel de confianza del 95%. Dentro del lado de manzana se seleccionan las viviendas luego de identificar aquellas que son aptas para el estudio (aquellas viviendas que se usan como lugar de habitación exclusivamente. La identificación se realiza mediante una visita de sensibilización en la cual se construye un plano a mano alzada del lado, en el cual se identifican las viviendas aptas. El propósito de este trabajo es presentar el diseño del plan de muestreo y su ejecución y proponerlo como un método utilizable para determinar cantidad de generación de residuos sólidos de origen residencial en ciudades de tamaño similar en países en vías de desarrollo.

    Full Text Available Los estudiosos de la familia residencial de las distintas disciplinas sociales en México no han tomado en cuenta las diferentes tradiciones culturales del país y han partido de un modelo de familia, como si México fuera un país homogéneo. El presente trabajo plantea el concepto de “sistema familiar mesoamericano”, que permite aprehender un tipo específico de ciclo de desarrollo de los grupos domésticos, característico de amplios sectores de la población rural de México. Uno de sus rasgos es la residencia virilocal, que favorece la formación de nuevas parejas sin necesidad de contar con vivienda propia. La consecuencia es una baja edad en el momento del matrimonio y el rápido crecimiento de la población, por lo que se puede hablar de un régimen demográfico asociado con este sistema familiar.

Los resultados muestran que la antigüedad y superficie son de-terminantes estadísticamente significativos en la formación del precio; el acceso aestaciones del Metro tiende a capitalizarse de forma no lineal, y tanto el ingreso delhogar como el agregado son variables económicamente significativas. La descompo-sición de precios revela que entre 68 a 71% del monto es explicado por determinantesrelacionados con los atributos de la propiedad, mientras que cerca de 68% del creci-miento observado entre 1990 y 2007 es consecuencia de determinantes macrofinan-cieros. Durante el periodo 2006-2007 la evolución de precios inmobiliarios no difierede manera significativa de la predicha por el modelo.

    Full Text Available Las caletas en Chile se remontan a tiempos prehispánicos y que presentan un modo de vida asociado a una economía familiar heredada por generaciones. Algunos de estos asentamientos sostienen relaciones de dependencia y conflicto con núcleos urbanos mayores. Tal es el caso de la bahía de Coquimbo, donde San Pedro y Peñuelas constituyen pequeños poblados en proceso de integración dentro del sistema conurbano de La Serena-Coquimbo. Por medio de un análisis socio-espacial se indaga en el grado de integración de estas localidades en el sistema urbano y las relaciones que establecen las comunidades de las caletas con su espacio habitado, identificando los elementos formales y espaciales más valorados y apropiados por sus habitantes, junto con los elementos de identidad comunitaria y su soporte contextual. Queda en evidencia la estrecha relación entre actividad productiva y espacio residencial, factor fundamental en la conservación y desarrollo identitario del borde costero, en un contexto de vulnerabilidad ante amenazas naturales y antrópicas.

El proceso de adaptación a un centro residencial es una de las situaciones estresantes a las que puede enfrentarse la persona mayor. Para poder sobreponerse ante dichas situaciones es fundamental la capacidad de resiliencia e incluso existen personas que buscan apoyo en la religiosidad o en las creencias en lo paranormal. En este trabajo se estudió la relación entre aleximitia, resiliencia y creencias paranormales en un grupo de 35 personas mayores (21 mujeres con edades entre 66 y 95 años de un centro institucionalizado. Se administraron la escala TAS-20 para la evaluación de la alexitimia, la Escala de Resiliencia CD-RISC y la Escala Mejorada de Creencias Paranormales. Entre los principales resultados cabe destacar que los sujetos con mayores Dificultades para identificar sentimientos son los que presentaban un menor Control personal; los sujetos con mayores Dificultades para identificar sentimientos son los que menor creencia poseían de las Formas de vida extraordinaria y los sujetos con mayor capacidad de Control Personal son los que mayor creencia tenían de las Formas de vida extraordinaria. Se discuten las aplicaciones que los profesionales pueden poner en marcha en centros institucionalizados de personas mayores.

    Full Text Available Las formas de diferenciación social –o si se prefiere, las desigualdades– encuentran en la vida social diversas formas de manifestarse. La apropiación del espacio urbano es una de ellas. En el Alentejo (Portugal, los contrastes sociales siempre han sido muy fuertes pero han sido la expresión de lógicas sociales diferentes según las épocas. La selección geográfica de los personajes importantes en la ciudad de Évora refleja las modificaciones de la estructura jerárquica. Así a la dispersión de los palacios, propio de la sociedad aristocrática hasta el siglo XIX sucede el reagrupamiento de las casas nobles en las calles principales propio de la fusión de la aristocracia y la burguesía mientras la gente pobre se situaba en las calles más estrechas. Finalmente, cincuenta años después, se evidencia una auténtica segregación residencial con el crecimiento de la ciudad extra-muros. Igualmente varía el uso de los lugares de sociabilidad en el centro histórico.

    Full Text Available Para la Región Metropolitana de Santiago de Chile (RMS, el cambio climático implica diferentes impactos que se suman a la continua expansión urbana y a cambios en los patrones de uso del suelo, los cuales a su vez acrecientan las amenazas hidroclimáticas, como las inundaciones y el calor extremo. En general, estos cambios tendrán notables consecuencias para la vulnerabilidad residencial. Especialmente las familias de bajos recursos y los asentamientos ilegales en grandes ciudades con crecimiento acelerado suelen ser los más vulnerables, debido a una mayor exposición y a una limitada capacidad de respuesta. Este artículo contrasta posiciones teóricas sobre las dimensiones socioeconómicas, físico-constructivas y urbano-rurales de la vulnerabilidad con evidencias empíricas, para entender quiénes son los más afectados por las inundaciones y el calor extremo en la Rms. Como muestran los resultados del estudio, las posiciones teóricas no se reflejan en los análisis cuantitativos. La vulnerabilidad depende de cada contexto y requiere políticas adecuadas para distintos territorios.

    Full Text Available El análisis de las unidades de consumo de agua asociadas a las actividades turísticas resulta imprescindible para valorar la efi ciencia ambiental y socioeconómica del modelo de desarrollo territorial urbano-turístico valenciano. Este trabajo analiza el gasto de agua urbano-turístico en las distintas formas de implantación territorial de estas actividades, especialmente en la modalidades de alojamiento hotelero y residencial, comparando la eficiencia de la gestión del agua potable en modelos urbanos de baja densidad y de alta densidad (concentrados. Para dicho fin se ha recurrido a un método empírico, mediante encuestas y trabajos de campo realizados en empresas de agua potable de los principales destinos turísticos de la Comunidad Valenciana. Con la colaboración de estas empresas, se han analizado los principales sistemas de abastecimiento para valorar las tendencias de consumo, la estacionalidad, el rendimiento técnico de las redes y el ciclo integral del agua. Asimismo, se incluyen resultados sobre el consumo de agua realizado en hoteles, en sus diferentes categorías. También en las distintas categorías de viviendas ocupadas por turistas y residentes en periodos de vacaciones, y en otros establecimientos vinculados a las actividades turísticas (restaurantes, camping, etc.

    Full Text Available Objetivo. En este trabajo se propone un esquema de tres fases para evaluar el riesgo en salud en las zonas mineras. La validación del esquema se efectuó en una zona de San Luis Potosí, México. Material y métodos. El monitoreo incluyó análisis de metales en suelo superficial, polvo residencial y agua de pozos. La biodisponibilidad se midió como el nivel de arsénico urinario en niños de las áreas contaminadas. La evaluación toxicológica consistió en análisis de la hepatotoxicidad (niveles de aspartato transaminasa y neurotoxicidad (niveles de dopamina y de sus metabolitos en ratas tratadas con residuos mineros. Resultados. Se encontró contaminación por arsénico y plomo en suelo y polvo. La biodisponibilidad fue positiva: 71% de los niños analizados tuvieron niveles urinarios de arsénico por arriba del valor normal. Los estudios de toxicidad mostraron daño hepático y alteraciones neuroquímicas en las ratas tratadas con el residuo. Conclusiones. El método fue útil para demostrar el riesgo en salud y para que las autoridades decidieran instrumentar un programa de restauración en la zona.

    Full Text Available Frente al excesivo consumo energético en el acondicionamiento térmico residencial, este estudio investiga la implicancia del clima local en las estrategias de expansión urbana, así como su grado de afección a las condiciones de confort, en el contexto mediterráneo español de la Costa del Sol Occidental. Para ello se realiza un análisis bioclimático territorial, identificando los diversos climas locales existentes y las diferentes respuestas biológicas asociadas a cada uno de ellos. Con estos resultados se elabora una clasificación del lugar desde la óptica de la idoneidad bioclimática. Esta herramienta ha permitido evaluar los procesos de planificación territorial, concluyéndose que el 80,6% del suelo urbano y urbanizable no se beneficia de las condiciones climáticas más favorables, las cuales constituyen el 47,3% del territorio analizado. Esta información, puesta al servicio de mejorar las condiciones térmicas de las ciudades, puede ser útil en el diseño y distribución de futuras áreas urbanas.

    Full Text Available Hoy hace una tarde tranquila. Por la ventana lateral del apartamento se cuela un zumbido espasmódico y ligero, lo producen los escasos automóviles que cruzan la avenida de cuando en cuando. El edificio que habito parece un Titán dormido, trasmite una molicie áspera y duradera, pero eso no quiebra la armonía del ambiente, por el contrario, le otorga sentido al clima, que es casi tibio. Son las cinco pasado el meridiano y los árboles juguetean con una brisa ligera y torpe, que de cuando en cuando choca con los cristales de las ventanas y se dispersa en fuga. Yo me acerco al balcón y observo las construcciones vecinas. Son moles grises, aunque su color sea blanco, verde o azul, parecen grises y dormitan igual que la antigua estructura desde donde fisgoneo. Vivo en una zona residencial de clase media, construida al interés de personas dispuestas a la caminata diurna y la larga y serena conversación vespertina. A doscientos metros de donde estoy hay una plaza, muchos árboles, una estación del Metro, varios locales comerciales y una gran avenida principal. Vivo en Altamira, baluarte de la reacción sociopolítica al gobierno del ex teniente coronel del ejército Hugo Chávez Frías.

    Full Text Available A associação entre características estruturais de vizinhanças e indicadores de crime e desordem tem recebido uma crescente atenção da criminologia nos últimos anos. Recentemente, os estudos têm enfatizado a relação entre as características contextuais das vizinhanças e o medo de crime. Neste artigo, em que o medo do crime é definido como uma reação emocional negativa devido à criminalidade, procurou-se incorporar às características individuais elementos relativos ao contexto da vizinhança na busca por evidências empíricas acerca da sua "ecologia social". Um modelo estatístico de regressão multinível foi elaborado a partir do survey de Vitimização realizado pelo Centro de Estudos de Criminalidade e Segurança Pública - Crisp/UFMG. Foi encontrada associação positiva entre as mulheres e os mais velhos com medo de crime, enquanto a estabilidade residencial tem efeito inverso. No nível da vizinhança, o principal resultado foi que a coesão social afeta a associação entre a taxa de criminalidade e o medo do crime.
