  1. Rio Vista gas leak study: Belleaire Gas Field, California

    Wilkey, P.L.

    1992-08-01

    The Rio Vista gas leak study evaluated methods for remotely sensing gas leaks from buried pipelines and developed methods to elucidate methane transport and microbial oxidation in soils. Remote-sensing methods were evaluated by singing gas leaks along an abandoned Pacific Gas and Electric (PG ampersand E) gas field collection line in northern California and applying surface-based and airborne remote-sensing techniques in the field, including thermal imaging, laser imaging, and multispectral imagery. The remote-sensing techniques exhibited limitations in range and in their ability to correlate with ground truth data. To elucidate methane transport and microbial oxidation in soils, a study of a controlled leak permitted field testing of methods so that such processes could be monitored and evaluated. Monitoring and evaluation techniques included (1) field measurement of soil-gas concentrations, temperatures, and pressures; (2) laboratory measurement of soil physical/chemical properties and activity of methane-oxidizing microorganisms by means of field samples; and (3) development of a preliminary numerical analysis technique for combined soil-gas transport/methane oxidation. Soil-gas concentrations at various depths responded rapidly to the high rate of gas leakage. The number of methane-oxidizing microorganisms in site soils rapidly increased when the gas leak was initiated and decreased after the leak was terminated. The preliminary field, laboratory, and numerical analysis techniques tested for this study of a controlled gas leak could be successfully applied to future studies of gas leaks. Because soil-gas movement is rapid and temporally variable, the use of several complementary techniques that permit generalization of site-specific results is favored

    One way to reduce the effects of anthropogenic greenhouse gases on climate is to inject carbon dioxide (CO2) from industrial sources into deep geological formations such as brine formations or depleted oil or gas reservoirs. In this study we develop a system-level model using GoldSim for geological CO2 storage to evaluate performance, economic, and subsequent health, safety and environmental (HSE) issues. The processes considered include CO2 capture and separation, compression, pipeline trans...

  3. Os jardins de Glaziou para a Quinta da Boa Vista, Rio de Janeiro / RJ

    Full Text Available O projeto dos jardins da Quinta da Boa Vista foi apresentado ao Imperador D. Pedro II por Auguste François-Marie Glaziou em 1868 e as obras, efetivamente, iniciadas em 1872. Construídos para o deleite não só da família imperial, seus convidados e das pessoas que moravam no interior da propriedade, o acesso era aberto à população em geral aos domingos, talvez, numa tentativa de acalmar os ânimos revolucionários do povo, tal qual acontecera na Inglaterra nos séculos anteriores. Inspirado nos jardins paisagísticos franceses, aliado aos conhecimentos das matas nacionais, o projeto executado por Glaziou para a Quinta da Boa Vista produz grande impacto nos frequentadores devido aos contrastes proporcionados. A utilização maciça de vegetação arbórea — principalmente em suas extremidades — produz um distanciamento visual da cidade que pode promover uma evasão tanto da situação geográfica como de seus problemas, gerando uma sensação de conforto e bem-estar, característica de vários parques da época.

Os resultados mostram que a mediação da proteção em redes se faz com pouca interatividade institucional pactuada e apenas informalmente, por meio de contatos, embora se reconheça um paradigma de ação integrada

  11. The natural gas and the possibilities of use in Rio de Janeiro State

    International Nuclear Information System (INIS)

    Carvalho, A.G.F. de; Almeida Luercio, C. de

    1990-01-01

    Although the Rio de Janeiro State owns one of Brazilian most important natural gas reserves and is responsible for 40% of country's natural gas production, the option to increase the utilization of this form of energy, in Rio, has been unexpectedly delayed. The warning that soon there will be a lack of electric power has already been given, and Rio's industrial activity, which has been growing above national average, may suffer irretrievable damages from this scarcity. Brazil is not self-sufficient as regards PLG yet, this fuel is heavily subsidized which thwarts competition in the residential market, with presently existing systems for distributing piped gas. It becomes necessary to remove barriers for obtaining resources and for incorporating PETROBRAS parallel distribution system into the State system, thus supplying the conditions for accelerating large scale use of natural gas in Rio de Janeiro.

    Full Text Available The objective of this study was to diagnose pests, diseases, weeds, and practices associated with the use of agrochemicals on the production of vegetables under protected conditions in Boa Vista, Roraima, Brazil. The descriptive study was conducted in urban and rural areas during February to April 2008, in the gardens monitored by Project Greenhouse, administered by the Municipal Development agricultural Secretary of the City. The data collection instrument was a semistructured questionnaire with 50 questions, applied in situ without notice to 75 farmers (47% of the population under study.Data were analyzed by descriptive statistics. After analyzing the data it was found that the whitefly, aphids, thrips and caterpillars were the insect pests that needed to be better controlled. The principal diseases were blight and leaf blight. Significant weed pests originated from the species of the families Poaceae, Cyperaceae, Amaranthaceae, and Portulacaeae. Relative to the use of pesticides, the results showed that 68% of farmers used insecticides, 24% fungicides, and 8% herbicides; 92% indicated that they had received some kind of technical guidance and 41.3% seek the technical assistance in order to acquire a pesticide. Therefore, we conclude that there is a high incidence of problems in plant vegetable gardens, intensive use of pesticides, a variety of formulations of insecticides, fungicides and herbicides associated with the adoption of practices and attitudes of risk for farmers, which can aggravate the direct and indirect problems of intoxication, and cause contamination to the environment. =Objetivou-se com esse trabalho fazer o diagnóstico das pragas, doenças, plantas daninhas e das práticas associadas ao uso dos agrotóxicos utilizados na produção de hortaliças, em ambiente protegido, no município de Boa Vista, Roraima.

    This paper presents the Conversion Project of Rio de Janeiro, Brazil, that converted all customers and the distribution network from Manufactured Gas (MG) to Natural Gas (NG), evaluating its logistic and benefits, highlighting those related to consumer safety. The Conversion Project was executed under the responsibility of CEG with the support of UERJ, specially on the definition and revision of the technical procedures as well as the quality assurance of the project execution. As main advantages followed by MG to NG network conversion, we can note: increasing of gas distribution network capacity and gas network operational condition improvements; elimination of production plant; revision and renovation of gas network; revision and repairing of building gas facilities; augmenting of NG usage; elimination of carbon monoxide as a supplied gas constituent. Conservation condition of most consumer internal gas facilities and ambient ventilation were so critical that conversion program resulted in no measurable accident prevention. The achieved safety level should be maintained through a periodically re-evaluation program of customer's gas facilities and appliances, with special focus on permanent ventilation required for NG safety usage.

    Lewis, J. R.; Irwin, M.; Bunclark, P.

    2010-12-01

    The VISTA telescope is a 4 metre instrument which has recently been commissioned at Paranal, Chile. Equipped with an infrared camera, 16 2Kx2K Raytheon detectors and a 1.7 square degree field of view, VISTA represents a huge leap in infrared survey capability in the southern hemisphere. Pipeline processing of IR data is far more technically challenging than for optical data. IR detectors are inherently more unstable, while the sky emission is over 100 times brighter than most objects of interest, and varies in a complex spatial and temporal manner. To compensate for this, exposure times are kept short, leading to high nightly data rates. VISTA is expected to generate an average of 250 GB of data per night over the next 5-10 years, which far exceeds the current total data rate of all 8m-class telescopes. In this presentation we discuss the pipelines that have been developed to deal with IR imaging data from VISTA and discuss the primary issues involved in an end-to-end system capable of: robustly removing instrument and night sky signatures; monitoring data quality and system integrity; providing astrometric and photometric calibration; and generating photon noise-limited images and science-ready astronomical catalogues.

Foram executados 15 ensaios em trechos de rios com características hidrodinâmicas distintas. Os experimentos mostraram que a utilização do GLP como fonte do traçador gasoso é viável, tanto do ponto de vista analítico, quanto do ponto de vista econômico. Do ponto de vista analítico, os resultados foram equiparáveis e até superiores à técnica tradicional de traçador gasoso. Do ponto de vista econômico, houve redução do custo para a realização de cada ensaio.The water oxygenation constitutes an important factor in the development of self-purification phenomenon in rivers.

    The Oil and Gas Information Center (CIPEG) of Rio de Janeiro Geological Survey concentrates data of oil and natural gas (O and G) industry in the State of Rio de Janeiro (RJ) and meet a specialist staff to work with this data. The CIPEG works in partnership with the Geology School of Rio de Janeiro State University. Its creation was motivated by the government necessity to dominate the techniques to calculate the Government take for the production of O and G front the RJ position in the national oil industry. In 2007, the Rio de Janeiro was responsible for 84% of domestic production of oil and of 91 municipalities, 86 received royalties. These resources represent substantial share in the budget of municipalities and the State, and any variation, could be bring deep impact on the economy of these counties and the State. The products of CIPEG are: a map of O and G industry in Rio de Janeiro, a Database, a GIS and a Timing of Predicting Production of O and G. These products are available through a Internet page with accompanying by graphs of the production of O and G or royalties and Web map for viewing the information in the GIS. (author)

  11. VISTA Reveals the Secret of the Unicorn

    Science.gov (United States)

    2010-10-01

    A new infrared image from ESO's VISTA survey telescope reveals an extraordinary landscape of glowing tendrils of gas, dark clouds and young stars within the constellation of Monoceros (the Unicorn). This star-forming region, known as Monoceros R2, is embedded within a huge dark cloud. The region is almost completely obscured by interstellar dust when viewed in visible light, but is spectacular in the infrared. An active stellar nursery lies hidden inside a massive dark cloud rich in molecules and dust in the constellation of Monoceros. Although it appears close in the sky to the more familiar Orion Nebula it is actually almost twice as far from Earth, at a distance of about 2700 light-years. In visible light a grouping of massive hot stars creates a beautiful collection of reflection nebulae where the bluish starlight is scattered from parts of the dark, foggy outer layers of the molecular cloud. However, most of the new-born massive stars remain hidden as the thick interstellar dust strongly absorbs their ultraviolet and visible light. In this gorgeous infrared image taken from ESO's Paranal Observatory in northern Chile, the Visible and Infrared Survey Telescope for Astronomy (VISTA [1], eso0949) penetrates the dark curtain of cosmic dust and reveals in astonishing detail the folds, loops and filaments sculpted from the dusty interstellar matter by intense particle winds and the radiation emitted by hot young stars. "When I first saw this image I just said 'Wow!' I was amazed to see all the dust streamers so clearly around the Monoceros R2 cluster, as well as the jets from highly embedded young stellar objects. There is such a great wealth of exciting detail revealed in these VISTA images," says Jim Emerson, of Queen Mary, University of London and leader of the VISTA consortium. With its huge field of view, large mirror and sensitive camera, VISTA is ideal for obtaining deep, high quality infrared images of large areas of the sky, such as the Monoceros R2 region

    The Yacuiba - Rio Grande Gas Pipeline is remote operated from the Supervision and Control Center (CSC) located in the offices of Transierra S.A. in Santa Cruz de la Sierra, Bolivia. This operation is made by means of a SCADA system based on satellite communication, it starts off at Yacuiba and finishes in Rio Grande, where it deliveries the export gas to Brazil. An Advanced Functions application was developed at the Transierra's CSC, This application runs under Intellution's iFix (HMI of the SCADA) in a Windows platform. It gathers transportation data in real time and by means of a mathematical process and a steady state simulation it makes the following on line calculations: Line Pack, Leak Detection, Transport Efficiency, Pressure Estimate in intermediate points and gas real velocity in the pipeline. The application was developed using Visual BASIC for Applications (VBA) (included in Intellution's iFix) and by means of an interphase to a historical server (iHistorian, Intellution) it is possible to store the obtained results, this integration also allows for the creation of graphs and trends with a great flexibility and to activate alarm points. With a practically null investment, this application replaces high cost specialized packages that are accessories to simulation or SCADA applications. (author)

  17. VISTA Stares Deeply into the Blue Lagoon

    Science.gov (United States)

    2011-01-01

    This new infrared image of the Lagoon Nebula was captured as part of a five-year study of the Milky Way using ESO's VISTA telescope at the Paranal Observatory in Chile. This is a small piece of a much larger image of the region surrounding the nebula, which is, in turn, only one part of a huge survey. Astronomers are currently using ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) to scour the Milky Way's central regions for variable objects and map its structure in greater detail than ever before. This huge survey is called VISTA Variables in the Via Lactea (VVV) [1]. The new infrared image presented here was taken as part of this survey. It shows the stellar nursery called the Lagoon Nebula (also known as Messier 8, see eso0936), which lies about 4000-5000 light-years away in the constellation of Sagittarius (the Archer). Infrared observations allow astronomers to peer behind the veil of dust that prevents them from seeing celestial objects in visible light. This is because visible light, which has a wavelength that is about the same size as the dust particles, is strongly scattered, but the longer wavelength infrared light can pass through the dust largely unscathed. VISTA, with its 4.1-metre diameter mirror - the largest survey telescope in the world - is dedicated to surveying large areas of the sky at near-infrared wavelengths deeply and quickly. It is therefore ideally suited to studying star birth. Stars typically form in large molecular clouds of gas and dust, which collapse under their own weight. The Lagoon Nebula, however, is also home to a number of much more compact regions of collapsing gas and dust, called Bok globules [2]. These dark clouds are so dense that, even in the infrared, they can block the starlight from background stars. But the most famous dark feature in the nebula, for which it is named, is the lagoon-shaped dust lane that winds its way through the glowing cloud of gas. Hot, young stars, which give off intense

    2005-10-01

    The U.S. Department of Energy and its predecessor agencies conducted a program in the 1960s and 1970s that evaluated technology for the nuclear stimulation of low-permeability gas reservoirs. The third and final project in the program, Project Rio Blanco, was conducted in Rio Blanco County, in northwestern Colorado. In this experiment, three 33-kiloton nuclear explosives were simultaneously detonated in a single emplacement well in the Mesaverde Group and Fort Union Formation, at depths of 1,780, 1,899, and 2,039 m below land surface on May 17, 1973. The objective of this work is to estimate lateral distances that tritium released from the detonations may have traveled in the subsurface and evaluate the possible effect of postulated natural-gas development on radionuclide migration. Other radionuclides were considered in the analysis, but the majority occur in relatively immobile forms (such as nuclear melt glass). Of the radionuclides present in the gas phase, tritium dominates in terms of quantity of radioactivity in the long term and contribution to possible whole body exposure. One simulation is performed for {sup 85}Kr, the second most abundant gaseous radionuclide produced after tritium.

    The natural gas pipeline transport is carried out by one or more compression stations. Each station possesses one or more compressors. The compressor's fuel is usually natural gas itself. The amount of natural gas consumed by the compressors fluctuates daily according to the demand at the city-gates. The daily operational result of a pipeline is known as imbalance. The imbalance is the difference between the natural gas entering into a in a pipeline and the volume delivered in the city-gates added to system use gas. The imbalance analyses in a pipeline that uses natural gas powered compressors requires the analyses of the system use gas. The aim of this work is to study the system use gas in the Bolivia-Brazil pipeline using the available data from the Superintendencia de Comercializacao e Movimentacao de Petroleo, seus Derivados e Gas Natural - ANP and compare the change of the volume consumed before and after the entry into operation of the Campinas-Rio gas pipeline.

    Comparison of DNA sequences from different species is a fundamental method for identifying functional elements in genomes. Here we describe the VISTA family of tools created to assist biologists in carrying out this task. Our first VISTA server at http://www-gsd.lbl.gov/VISTA/ was launched in the summer of 2000 and was designed to align long genomic sequences and visualize these alignments with associated functional annotations. Currently the VISTA site includes multiple comparative genomics tools and provides users with rich capabilities to browse pre-computed whole-genome alignments of large vertebrate genomes and other groups of organisms with VISTA Browser, submit their own sequences of interest to several VISTA servers for various types of comparative analysis, and obtain detailed comparative analysis results for a set of cardiovascular genes. We illustrate capabilities of the VISTA site by the analysis of a 180 kilobase (kb) interval on human chromosome 5 that encodes for the kinesin family member3A (KIF3A) protein.

    The scope of this paper is to discuss the main factors that pushed the increase of the industrial utilization of natural gas in Rio de Janeiro and the structural imbalance between supply and demand in this market on the second semester of 2007. The shortage in October 2007 brought uncertainty to the energetic supply to the industrial sector, and leaded to a crisis in January 2008. In order to evaluate the hindrances and to propose solutions aiming to prevent future crisis, the Federation of Industries of Rio de Janeiro - Sistema FIRJAN - did a research along with industries that represent the majority part of the industrial demand of natural gas in Rio de Janeiro. The main results show that the industries are inclined to adapt to this new reality by lowering the consumption of natural gas. Nonetheless, environmental, institutional and economic issues make it difficult, and sometimes impossible, to implement the change. Beyond mapping the Rio de Janeiro industry's consumption of natural gas, this paper calls for the necessity of a long-run energetic planning in order to face the challenges that are being posed to the natural gas chain.

    Full Text Available The aim of this research was to evaluate the quality of groundwater in areas of permanent preservation (Guarani Aquifer System – GAS in the Rio Pardo Hydrographical Basin, RS, Brazil, using physical, chemical and microbiological variables, based on resolution no. 396/2008 of the National Council on the Environment - CONAMA. Nine sampling points were distributed throughout the basin, where groundwater was classified as the major ions through the Piper diagram. The results indicated that most of the wells evaluated were classified in Class 4, accounting for water uses less restrictive. However, it should be considered that the aquifers are characterize by different geological conditions, having intrinsical physical, chemical and biological variables with hydrogeochemical variations, requiring that their quality levels are often based on these characteristics, as noted in diagram Piper, where the samples P1, P2, P3, P5 and P9 were classified as calcium bicarbonate, the waters of the points P4, P6, P7 as sodium bicarbonate and P8 as sulfated. It was found that the quality of water from wells with depths less than 6 m are becoming more vulnerable due to anthropogenic activities, as showing by the concentration of nitrate, total and thermotolerant coliforms, while the quality of water from deeper wells basically depends on their hydrogeological and hydrogeochemical characteristics based on the concentration of sodium and sulfate variables. However, they also showed contamination by human activities, mainly by the nitrate variable.

  5. Nuclear fuel cycle simulation system (VISTA)

    International Nuclear Information System (INIS)

    2007-02-01

    The Nuclear Fuel Cycle Simulation System (VISTA) is a simulation system which estimates long term nuclear fuel cycle material and service requirements as well as the material arising from the operation of nuclear fuel cycle facilities and nuclear power reactors. The VISTA model needs isotopic composition of spent nuclear fuel in order to make estimations of the material arisings from the nuclear reactor operation. For this purpose, in accordance with the requirements of the VISTA code, a new module called Calculating Actinide Inventory (CAIN) was developed. CAIN is a simple fuel depletion model which requires a small number of input parameters and gives results in a very short time. VISTA has been used internally by the IAEA for the estimation of: spent fuel discharge from the reactors worldwide, Pu accumulation in the discharged spent fuel, minor actinides (MA) accumulation in the spent fuel, and in the high level waste (HLW) since its development. The IAEA decided to disseminate the VISTA tool to Member States using internet capabilities in 2003. The improvement and expansion of the simulation code and the development of the internet version was started in 2004. A website was developed to introduce the simulation system to the visitors providing a simple nuclear material flow calculation tool. This website has been made available to Member States in 2005. The development work for the full internet version is expected to be fully available to the interested parties from IAEA Member States in 2007 on its website. This publication is the accompanying text which gives details of the modelling and an example scenario

    The possibility of an exchange of energy for heating residential water should be seen, by the point of view of the concessionaires, as a single market and exclusionary, in which the development of new customers by the concessionaire of electric energy directly involves the development of these non-customers for the distributor of natural gas. The study shows that, under the terms of concession of electricity, the loss of any part of the markets, current and expansion would be attractive only if the natural gas concessionaire could pass part of their earnings with customers users of electric showers that change their profile to the gas heaters, for electrical distribution. Under the terms of the concession to natural gas, the condition of massive investments replacement of electric showers and absorption of growth and expansion entrant with customers, increase the turnover to allow the search of a mechanism for transferring part of that revenue to absorb also customers of electricity. Thus, both the concessionaire of electricity preserve their revenue and, in turn, the concessionaire of natural gas would have an effective gain of revenue for the absorption of the customers of electric showers.

    Methane (CH4) is a potent greenhouse gas (GHG) and a critical target of climate mitigation efforts. However, actionable emission reduction efforts are complicated by large uncertainties in the methane budget on relevant scales. Here, we present Vista, a Geographic Information System (GIS)-based approach to map potential methane emissions sources in the South Coast Air Basin (SoCAB) that encompasses Los Angeles, an area with a dense, complex mixture of methane sources. The goal of this work is to provide a database that, together with atmospheric observations, improves methane emissions estimates in urban areas with complex infrastructure. We aggregated methane source location information into three sectors (energy, agriculture, and waste) following the frameworks used by the State of California GHG Inventory and the Intergovernmental Panel on Climate Change (IPCC) Guidelines for GHG Reporting. Geospatial modeling was applied to publicly available datasets to precisely geolocate facilities and infrastructure comprising major anthropogenic methane source sectors. The final database, Vista-Los Angeles (Vista-LA), is presented as maps of infrastructure known or expected to emit CH4. Vista-LA contains over 33 000 features concentrated on Vista-LA is used as a planning and analysis tool for atmospheric measurement surveys of methane sources, particularly for airborne remote sensing, and methane hotspot detection using regional observations. This study represents a first step towards developing an accurate, spatially resolved methane flux estimate for point sources in SoCAB, with the potential to address discrepancies between bottom-up and top-down methane emissions accounting in this region. The Vista-LA datasets and associated metadata are available from the Oak Ridge National Laboratory Distributed Active Archive Center for Biogeochemical Dynamics (ORNL DAAC; https://doi.org/10.3334/ORNLDAAC/1525).

    This study focuses on the presence of radon ( 222 Rn) and volatile organic compounds (VOCs) in soil gases at a gas station located in the city of Rio Claro, São Paulo, Brazil, where a fossil fuel leak occurred. The spatial distribution results show a correlation between 222 Rn and VOCs, consistent with the fact that radon gas has a greater chemical affinity with organic phases than with water. This finding demonstrates that the presence of a residual hydrocarbon phase in an aquifer can retain radon, leading to a reduced radon content in the soil gas. The data in this study confirm the results of previous investigations, in which the method used in this study provided a preliminary fingerprint of a contaminated area. Furthermore, the data analysis time is brief, and only simple equipment is required. - Highlights: • 222 Rn in soil gases. • Correlation between 222 Rn and VOCs. • Useful method as a preliminary fingerprint of a contaminated area

    In this paper, we describe the routine photometric calibration of data taken with the VISTA infrared camera (VIRCAM) instrument on the ESO Visible and Infrared Survey Telescope for Astronomy (VISTA) telescope. The broad-band ZYJHKs data are directly calibrated from Two Micron all Sky Survey (2MASS) point sources visible in every VISTA image. We present the empirical transformations between the 2MASS and VISTA, and Wide-Field Camera and VISTA, photometric systems for regions of low reddening. We investigate the long-term performance of VISTA+VIRCAM. An investigation of the dependence of the photometric calibration on interstellar reddening leads to these conclusions: (1) For all broad-band filters, a linear colour-dependent correction compensates the gross effects of reddening where E(B - V) < 5.0. (2) For Z and Y, there is a significantly larger scatter above E(B - V) = 5.0, and insufficient measurements to adequately constrain the relation beyond this value. (3) The JHKs filters can be corrected to a few per cent up to E(B - V) = 10.0. We analyse spatial systematics over month-long time-scales, both inter- and intradetector and show that these are present only at very low levels in VISTA. We monitor and remove residual detector-to-detector offsets. We compare the calibration of the main pipeline products: pawprints and tiles. We show how variable seeing and transparency affect the final calibration accuracy of VISTA tiles, and discuss a technique, grouting, for mitigating these effects. Comparison between repeated reference fields is used to demonstrate that the VISTA photometry is precise to better than ≃ 2 per cent for the YJHKs bands and 3 per cent for the Z bands. Finally, we present empirically determined offsets to transform VISTA magnitudes into a true Vega system.

    Here we describe results from a tracer test in the Cerros del Rio basalt beneath Mesita del Buey, Technical Area 54 (TA-54) at Los Alamos National Laboratory (LANL or the Laboratory). This report follows from plans outlined in our previous Tracer Test Work Plan (LANL 2016). These activities were conducted by LANL to further characterize subsurface properties of the Cerros del Rio basalts at Material Disposal Area (MDA) L (Figure 1.1-1). The work presented follows from the “Interim Measures Work Plan for Soil-Vapor Extraction of Volatile Organic Compounds from Material Disposal Area L, Technical Area 54, Revision 1,” submitted to the New Mexico Environment Department (NMED) in September 2014 (LANL 2014). Remediation of the MDA L vapor plume by soil-vapor extraction (SVE) is recommended as part of the final remedy in the “Corrective Measures Evaluation Report for Material Disposal Area L, Solid Waste Management Unit 54-006, at Technical Area 54, Revision 2” to meet a remedial action objective of preventing groundwater from being impacted above a regulatory standard by the transport of volatile organic compounds (VOCs) to groundwater through soil vapor (LANL 2011).

    In order to fulfill contractual agreements, three Bolivian companies decided to create Transierra S.A., a gas transportation company that would increase the gas transportation capacity from the gas fields, located in the Southern part of Bolivia. The overall objective was to build and operate a gas pipeline from Yacuiba to Rio Grande in time to comply with already agreed dates to star commercial operation. The creation of the company and the construction process were conducted in a highly competitive and regulated environment. Construction completion schedules were tight; therefore, under the previously mentioned scenario, the company implemented creative strategies to achieve its goals. (author)

  19. Radiation shielding calculations for the vista spacecraft

    2005-01-01

    The VISTA spacecraft design concept has been proposed for manned or heavy cargo deep space missions beyond earth orbit with inertial fusion energy propulsion. Rocket propulsion is provided by fusion power deposited in the inertial confined fuel pellet debris and with the help of a magnetic nozzle. The calculations for the radiation shielding have been revised under the fact that the highest jet efficiency of the vehicle could be attained only if the propelling plasma would have a narrow temperature distribution. The shield mass could be reduced from 600 tons in the original design to 62 tons. Natural and enriched lithium were the principle shielding materials. The allowable nuclear heating in the superconducting magnet coils (up to 5 mW/cm 3 ) is taken as the crucial criterion for dimensioning the radiation shielding structure of the spacecraft. The space craft mass is 6000 tons. Total peak nuclear power density in the coils is calculated as ∼5.0 mW/cm 3 for a fusion power output of 17 500 MW. The peak neutron heating density is ∼2.0 mW/cm 3 , and the peak γ-ray heating density is ∼3.0 mW/cm 3 (on different points) using natural lithium in the shielding. However, the volume averaged heat generation in the coils is much lower, namely 0.21, 0.71 and 0.92 mW/cm 3 for the neutron, γ-ray and total nuclear heating, respectively. The coil heating will be slightly lower if highly enriched 6 Li (90%) is used instead of natural lithium. Peak values are then calculated as 2.05, 2.15 and 4.2 mW/cm 3 for the neutron, γ-ray and total nuclear heating, respectively. The corresponding volume averaged heat generation in the coils became 0.19, 0.58 and 0.77 mW/cm 3

  20. Gonadotropin releasing hormone agonists: Expanding vistas

    2011-01-01

    Full Text Available Gonadotropin-releasing hormone (GnRH agonists are derived from native GnRH by amino acid substitution which yields the agonist resistant to degradation and increases its half-life. The hypogonadotropic hypogonadal state produced by GnRH agonists has been often dubbed as "pseudomenopause" or "medical oophorectomy," which are both misnomers. GnRH analogues (GnRH-a work by temporarily "switching off" the ovaries. Ovaries can be "switched off" for the therapy and therapeutic trial of many conditions which include but are not limited to subfertility, endometriosis, adenomyosis, uterine leiomyomas, precocious puberty, premenstrual dysphoric disorder, chronic pelvic pain, or the prevention of menstrual bleeding in special clinical situations. Rapidly expanding vistas of usage of GnRH agonists encompass use in sex reassignment of male to female transsexuals, management of final height in cases of congenital adrenal hyperplasia, and preserving ovarian function in women undergoing cytotoxic chemotherapy. Hypogonadic side effects caused by the use of GnRH agonists can be tackled with use of "add-back" therapy. Goserelin, leuprolide, and nafarelin are commonly used in clinical practice. GnRH-a have provided us a powerful therapeutic approach to the treatment of numerous conditions in reproductive medicine. Recent synthesis of GnRH antagonists with a better tolerability profile may open new avenues for both research and clinical applications. All stakeholders who are partners in women′s healthcare need to join hands to spread awareness so that these drugs can be used to realize their full potential.

    The vista paradox is the illusion in which an object seen through a frame appears to shrink in apparent size as the observer approaches the frame. In four studies, we tested the effect of framing and fixating on the target object. The first two studies assessed the vista paradox in a large scale...... inserted within five frames differing in size. In the fourth study linear perspective was added to the images. The results showed that both frame size and linear perspective cues were critical factors for the vista paradox illusion....

    In 2007, the U.S. Department of Energy joined the California Energy Commission in funding a project to begin to examine the technical, economic and institutional (policy and regulatory) aspects of energy-efficient community development. That research project was known as the Chula Vista Research Project for the host California community that co-sponsored the initiative. The researches proved that the strategic integration of the selected and economically viable buildings energy efficiency (EE) measures, photovoltaics (PV), distributed generation (DG), and district cooling can produce significant reductions in aggregate energy consumption, peak demand and emissions, compared to the developer/builder's proposed baseline approach. However, the central power plant emission reductions achieved through use of the EE-DG option would increase local air emissions. The electric and natural gas utility infrastructure impacts associated with the use of the EE and EE-PV options were deemed relatively insignificant while use of the EE-DG option would result in a significant reduction of necessary electric distribution facilities to serve a large-scale development project. The results of the Chula Vista project are detailed in three separate documents: (1) Energy-Efficient Community Development in California; Chula Vista Research Project report contains a detailed description of the research effort and findings. This includes the methodologies, and tools used and the analysis of the efficiency, economic and emissions impacts of alternative energy technology and community design options for two development sites. Research topics covered included: (a) Energy supply, demand, and control technologies and related strategies for structures; (b) Application of locally available renewable energy resources including solar thermal and PV technology and on-site power generation with heat recovery; (c) Integration of local energy resources into district energy systems and existing

    The Bolivia-Brazil Natural Gas Pipeline has 2.593 kilometers since Rio Grande City in Bolivia until Canoas City, in south Brazil. The pipeline crosses a lot of types of geological fields and difficult topography. The south spread of the gas pipeline is the most interesting because of its hard topography combined with the variety of geological materials, such as, colluvium deposits and debris flow areas. Curriola River is located at the kilometer 408, north part of Parana State. In this area, the pipeline crosses slopes of 45 degrees of inclination. The down part of Curriola's slope is composed by a non-resistance material (clay and little rock blocks) with a high porosity. Every year, during the rainy seasons, tension cracks are observed evidencing the earth movement. The slope stability is above the minimum expected for pipeline operation. The aim of this paper is to present the site characterization of the Curriola River Slope, together with all the investigation made in order to supply the studies with condensed information for the slope stabilization.

    At the world-wide Earth Summit held in Rio de Janeiro in 1992, two new legally binding documents were signed by over 140 countries: the Convention on Climate Change and the Convention on Biological Diversity. These conventions will come into force when ratified by 50 and 30 countries respectively. The objectives of these conventions, the steps to be taken toward their compliance, and their implications for Canada are discussed. Since climatic change could bring about adverse effects such as water shortages and loss of permafrost, Canada has committed itself to a quick start toward compliance with preparation of a detailed national inventory of greenhouse gas emissions. The biodiversity convention could make it harder to develop hydropower in Canada at the same time that the climate change convention makes hydropower more attractive. Other documents from the Earth Summit included declarations on forestry management, sustainable development, and future conventions on desertification and fishing. Notable features of the summit included a refocusing of the environmental agenda to the priorities of the poorer countries, a recognition that environmental issues are linked to poverty and economic development, and an attack on the consumption patterns of the richer countries.

    Full Text Available Grapevine plants have been grown in different tropical regions of Brazil. In the state of Roraima, this culture was introduced commercially in 2005 in Boa Vista. Unlike temperate regions, tropical regions present thermal conditions for grape production throughout the year. To evaluate the climatic characteristics on different periods of the year, it can be used different indices. The objective of this study was to characterize climate suitability of Boa Vista, Roraima, Brazil, for grapevine cultivation at different months of the year. For climate classification it was used the Geoviticulture Multicriteria Climatic Classification System (CCM, which is composed by three indices: Heliothermal (IH, Cool Night (IF, and Drought (IS. It was also used the Zuluaga Index (IZ, to assess the risk of incidence of fungal diseases on the vine, especially in relation to the incidence of downy mildew (Plasmopara viticola, one of the main grapevine diseases in humid regions. Based on the evaluated indices, it was found that the most favorable period for grape production goes from October to March because of the lower values of rainfall. During the other months, it can be employed branch pruning without fruit production, as occurs in other tropical locations of Brazil. =A videira tem sido cultivada em diferentes regiões tropicais do Brasil.

    The radon is a radioactive gas. It occurs naturally in the atmosphere coming from the decay of radium, with emission of alpha particles. There are three radon isotopes more known, of which the most important under the environmental point of view is the Rn-222, whose half life is 3.82 days. The radon and their descendants are responsible by more than 40 % of the natural radioactive dose received for the human beings inside the building. In doses above 4 pCi/l, given as occupational dose, can cause among other diseases, the lung cancer. The main source of radon inside the building is the soil. The incidence of radon inside the building varies according to the soil composition, the materials employed in its construction, the inside air temperature and humidity, time during the day, season and the ventilation process designed. The work was realized at the commercial centers in Rio de Janeiro and Pocos de Caldas, for methodology confirmation. It was utilized the passive (track detectors) and active (two filters technique. Kusnetz technique, Tsivoglou technique and alpha spectrometry technique) methods. The objective of this work was to analyze the radon and thoron concentrations levels in order to supply parameters upon the quality of the air in those commercial centers. (author)

    Numerical modeling is a fundamental tool for studying the earth system components along with weather and climate forecast. In fact, the development of on-line models allows to simulate conditions of the atmosphere, for example, to evaluate certain chemicals in weather events with the purpose of improving a region's quality of air. For this determined purpose, the on-line models employ information from a broad range of sources in order to generate its variables forecasts. But beyond vast information sources, for a region's quality of air study, the data concerning the amount and distribution of emissions of polluting gases must be representative, as well as, it's required complete georeferenced emissions for simulations made with high resolution. Consequently, the modifications made in this work to the PREP-CHEM-SRC (Preprocessor of trace gas and aerosol emission fields for regional and a global atmospheric chemistry models) tool are presented to meliorate the initialization files for BRAMS models, 5.2 version (Brazilian Developments on the Regional Atmospheric Modeling System) and WRF (Weather Research and Forecasting Model) with vehicle emissions in the state of Rio de Janeiro, Brazil. It was determined the annual vehicle emission, until the year 2030, of the nitrogen oxides species (NOx) and carbon monoxide (CO) for each city and using different scenarios. For Rio de Janeiro city, a process of distribution by emissions of the main pollutant gases was implemented. In total, five different types of routes were used and the emission percentage for each one was calculated using the most current traffic information in them. For to check the industrial contributions to the emissions were used the global datasets RETRO (REanalysis of TROpospheric chemical composition) and EDGAR-HTAP (Emission Database for Global Atmospheric Research). On the other hand, for the biogenic contributions was used information from the MEGAN model (Model of Emissions of Gases and Aerosols

    Full Text Available Uma das formas das empresas comunicarem as mudanças nos seus processos e produtos aos seus consumidores é por meio da adoção de selos verdes. Entretanto, diante de um grande número de selos e programas, é necessário observar melhor o consumidor neste contexto. Desta forma, o artigo objetiva apontar e discutir o conhecimento e o ponto de vista dos consumidores no que diz respeito à rotulagem ambiental de produtos. A pesquisa foi desenvolvida por meio de um questionário de base online, entre os meses de fevereiro a agosto de 2015, e participaram 417 respondentes, todos residentes no Brasil. Percebe-se que ainda há pouco conhecimento dos consumidores no que diz respeito aos selos, assim como intenção de consumo dos produtos certificados. Porém, pode-se apontar para o surgimento dessa nova demanda e que, havendo um aumento da conscientização, aliado à educação para um consumo consciente, o engajamento pode ser maior.

O referido romance faz parte de Inferno provisório (2005-2011, um painel romanesco que objetiva dar voz ao trabalhador brasileiro de classe média baixa, personagem, em geral, pouco representada pela literatura nacional.Considerando a premissa de Walter Benjamin, pensador alemão que em 1940 intuía que o progresso vigente estava prenhe de armadilhas e propunha ao materialista histórico que abordasse o avesso da história e valorizasse a voz dos oprimidos, realizando um processo de “escovar a história a contrapelo”, o intuito desse artigo é apresentar uma leitura de Vista parcial da noite como o avesso da história da modernização de nosso país. Para isso, consideramos, em nossa leitura, o contexto histórico representado no romance – a década de 1970 de regime ditatorial reconhecido pela história oficial como o período de grande progresso e do milagre econômico brasileiro.

    Stroke rehabilitation is a complex intervention. Many factors influence the interaction between the patient and the elements of the intervention. Rehabilitation interventions are aimed at altering different domains of patient outcome including body functions, activity and participation. As a consequence, randomised clinical trials in this area are difficult to design. We developed an archive of stroke rehabilitation trials (VISTA-Rehab) to act as a resource to help trialists model and design future rehabilitation studies. We developed specific eligibility criteria for the entry of stroke rehabilitation trials into the archive. We established a Steering Committee to oversee projects and publications and commenced the recruitment of rehabilitation trials into this resource. As of August 2009, VISTA-Rehab contains data from 23 stroke rehabilitation trials (>3400 patients). Demographic data, including age [median=73, interquartile range (63,79)], gender (male=53%) and initial dependency [median baseline Barthel index score=6, interquartile range (9,19)], are available for all patients. Outcome measures include the modified Rankin Scale, Barthel Index, Rivermead Motor Assessment, Fugl-Meyer Assessment, General Health Questionnaire and Nottingham Extended Activities of Daily Living Scale. VISTA-Rehab expands the Virtual International Stroke Trials Archive to include rehabilitation trials. Anonymised data can be used to examine questions specific to stroke rehabilitation and to generate novel hypotheses. © 2010 The Authors.

    Full Text Available Pesquisas indicam que o processo de desflorestamento na Amazônia está associado à abertura de estradas, uma vez que favorece o fluxo migratório, a ocupação de terras e a exploração de madeiras. O objetivo deste trabalho foi analisar o desflorestamento no entorno (20 km da rodovia BR-174 para um período de 30 anos (1978-2008. Foram utilizadas imagens LANDSAT, dados do INPE/PRODES, dados cartográficos e econômicos e trabalhos de campo. Os resultados demonstraram um crescimento do desflorestamento, passando de 622,15 km2 em 1978 para 2.618,58 km2 em 2008. As principais atividades econômicas dos municípios por onde passa a BR-174, exceto Manaus, estão associadas à agropecuária. Em Manaus, o desflorestamento ocorre principalmente na área urbana. Ainda que a construção da BR-174 esteja associada a processos de desflorestamento, a rodovia possui grande importância para a região, pois foi responsável pela ligação terrestre entre duas capitais do norte do país (Manaus/AM e Boa Vista/RR e possibilitou formar comunidades onde são desenvolvidas atividades econômicas e sociais. A criação de projetos de desenvolvimento sustentável é o grande desafio dos governos locais, para agregar valor aos empreendimentos existentes e desenvolver novos modelos de uso e ocupação na região.

    The VistaCam® intra-oral camera system (Dürr Dental, Bietigheim-Bissingen, Germany) is a fluorescence system using light emitting diodes that produce a 405-nm violet light. This wavelength has potential application for detection of dental calculus based on red emissions from porphyrin molecules. This study assessed the digital scores obtained for both supragingival and subgingival calculus on 60 extracted teeth and compared these with lesions of dental caries. It has also examined the effect of saliva and blood on the fluorescence readings for dental calculus. VistaCam fluorescence scores for both supragingival (1.7-3.3) and subgingival calculus (1.3-2.4) were higher than those for sound root surfaces (0.9-1.1) and dental caries (0.9-2.2) ( p  calculus samples were not affected by the presence of saliva or blood. These results suggest that the use of violet light fluorescence could be a possible adjunct to clinical examination for deposits of dental calculus.

    The vista paradox is the illusion in which an object seen through a frame appears to shrink in apparent size as the observer approaches the frame. In four studies, we tested the effect of framing and fixating on the target object. The first two studies assessed the vista paradox in a large scale...... naturalistic setting in which a 162.26 m long corridor was aligned to a 97.2 m high tower (1407 m away). In the first study the results showed, for each 16 m section, a mean 9.95% enlargement of the tower moving backward, and a mean 11.62% shrinking moving forward. In the second study participants had...... to compensate perceived width change changing the focal length of a photographic zoom lens. The results showed, for each 16 m section, a mean change in optical size of 26.37% in the experimental condition, and of 53.08% in the control condition. In the third study, we presented an identical vertical rectangle...

    2010-09-08

    To achieve breakthrough scientific discoveries in the 21st century, a convergence and integration of world-leading experimental facilities and capabilities with theory, modeling, and simulation is necessary. In this issue of Experimental Physical Sciences Vistas, I am excited to present our plans for Los Alamos National Laboratory's future flagship experimental facility, MaRIE (Matter-Radiation Interactions in Extremes). MaRIE is a facility that will provide transformational understanding of matter in extreme conditions required to reduce or resolve key weapons performance uncertainties, develop the materials needed for advanced energy systems, and transform our ability to create materials by design. Our unique role in materials science starting with the Manhattan Project has positioned us well to develop a contemporary materials strategy pushing the frontiers of controlled functionality - the design and tailoring of a material for the unique demands of a specific application. Controlled functionality requires improvement in understanding of the structure and properties of materials in order to synthesize and process materials with unique characteristics. In the nuclear weapons program today, improving data and models to increase confidence in the stockpile can take years from concept to new knowledge. Our goal with MaRIE is to accelerate this process by enhancing predictive capability - the ability to compute a priori the observables of an experiment or test and pertinent confidence intervals using verified and validated simulation tools. It is a science-based approach that includes the use of advanced experimental tools, theoretical models, and multi-physics codes, simultaneously dealing with multiple aspects of physical operation of a system that are needed to develop an increasingly mature predictive capability. This same approach is needed to accelerate improvements to other systems such as nuclear reactors. MaRIE will be valuable to many national

    Recent advances in sequencing technologies promise better diagnostics for many diseases as well as better understanding of evolution of microbial populations. Single Nucleotide Polymorphisms(SNPs) are established genetic markers that aid in the identification of loci affecting quantitative traits and/or disease in a wide variety of eukaryotic species. With today's technological capabilities, it is possible to re-sequence a large set of appropriate candidate genes in individuals with a given disease and then screen for causative mutations.In addition, SNPs have been used extensively in efforts to study the evolution of microbial populations, and the recent application of random shotgun sequencing to environmental samples makes possible more extensive SNP analysis of co-occurring and co-evolving microbial populations.

    An innovative concept for the direct utilisation of fusion energy with laser ignited (D,T) capsules for propulsion is presented with the so called VISTA (Vehicle for Interplanetary Space Transport Applications) concept. VISTA's overall geometry is that of a 50 degrees-half-angle cone to avoid massive radioactive shielding. The 50 degrees-half-angle maximizes the jet efficiency, and is determined by selecting the optimum pellet firing position along the axis of the cone with respect to the plane of the magnet coil. The pellet firing position is in the vacuum. By a total fusion power production of 17 500 MW with a repetition rate of 5 Hz and 3 500 MJ per shot, the propulsion power in form of charged particles has been calculated as {approx} 7 000 MW, making {approx} 40 % of the total fusion power. About 60 % of the fusion energy is carried by the leaking neutrons out of the pellet. Most of them (96 %) escape into vacuum without striking the space ship. Only 4 % enter the frozen hydrogen exhaust cone (about 50 gr.). Total peak nuclear heat generation in the coils is calculated as 4.7 mW/cm{sup 3}. The peak neutron heating is 1.9 mW/cm{sup 3} and the peak {gamma}-ray heating density is 2.8 mW/cm{sup 3}. However, volume averaged nuclear heat generation in the coils is much lower. It is calculated as 0.18, 0.48 and 0.66 mW/cm{sup 3} for neutron, {gamma}-ray and total nuclear heating, respectively. Net shielding mass is found as 170 ton, making < 3 % of the vehicle mass.

    El Paso Natural Gas Co.'s largest expansion program in its 64-year history will be completed along its northern system this spring or early summer. According to the company, the three-tiered, $241.5 million expansion program will increase El Paso's gas-transport capacity by 835 MMcfd to 2.5 bcfd of conventional and coal-seam gas from the San Juan basin in northwestern New Mexico. That's enough natural gas, says the company, to supply the needs of a city of more than 800,000 residents. This paper reports that the expansion involves the San Juan Triangle system, the company's northern main line, and the Permian-San Juan crossover line. The company also filed with the Federal Energy Regulatory Commission (FERC) in October 1991 to construct a new $15.2 million compressor station, Rio Vista, south of Bloomfield, N.M. The station would be used to move additional gas to the main line

    Context. Orion A hosts the nearest massive star factory, thus offering a unique opportunity to resolve the processes connected with the formation of both low- and high-mass stars. Here we present the most detailed and sensitive near-infrared (NIR) observations of the entire molecular cloud to date. Aims: With the unique combination of high image quality, survey coverage, and sensitivity, our NIR survey of Orion A aims at establishing a solid empirical foundation for further studies of this important cloud. In this first paper we present the observations, data reduction, and source catalog generation. To demonstrate the data quality, we present a first application of our catalog to estimate the number of stars currently forming inside Orion A and to verify the existence of a more evolved young foreground population. Methods: We used the European Southern Observatory's (ESO) Visible and Infrared Survey Telescope for Astronomy (VISTA) to survey the entire Orion A molecular cloud in the NIR J,H, and KS bands, covering a total of ~18.3 deg2. We implemented all data reduction recipes independently of the ESO pipeline. Estimates of the young populations toward Orion A are derived via the KS-band luminosity function. Results: Our catalog (799 995 sources) increases the source counts compared to the Two Micron All Sky Survey by about an order of magnitude. The 90% completeness limits are 20.4, 19.9, and 19.0 mag in J,H, and KS, respectively. The reduced images have 20% better resolution on average compared to pipeline products. We find between 2300 and 3000 embedded objects in Orion A and confirm that there is an extended foreground population above the Galactic field, in agreement with previous work. Conclusions: The Orion A VISTA catalog represents the most detailed NIR view of the nearest massive star-forming region and provides a fundamental basis for future studies of star formation processes toward Orion.

    Samples of ''sandstone'' from near the site of the upper Rio Blanco nuclear explosion were heated in the laboratory at temperatures between 600 and 900 0 C. The composition and amount of noncondensable (dry) gas released were measured and compared to the amount and composition of gas found underground following the explosion. The gas released from the rock heated in the laboratory contained approximately 80 percent CO 2 and 10 percent H 2 ; the balance was CO and CH 4 . With increasing temperature, the amounts of CO 2 , CO, and H 2 released increased. The composition of gas released by heating Rio Blanco rock in the laboratory is similar to the composition of gas found after the nuclear explosion except that it contains less natural gas (CH 4 , C 2 H 6 . . .). The amount of noncondensable gas released by heating the rock increases from approximately 0.1 mole/kg of rock at 600 0 C to 0.9 mole/kg at 900 0 C. Over 90 percent of the volatile components of the rock are released in less than 10 h at 900 0 C. A comparison of the amount of gas released by heating rock in the laboratory to the amount of gas released by the heat of the Rio Blanco nuclear explosion suggests that the explosion released the volatile material from about 0.42 mg of rock per joule of explosive energy (1700 to 1800 tonnes per kt).

    Health impact assessment (HIA) researchers regularly use community input in their investigations to help them better understand local health issues. Community data is commonly associated with the lived experiences of local impacted residents known as 'emic' data. It is becoming more common practice for HIA researchers to access outside experts and stakeholders ('etic' data) during the community input phase of their investigations. Utilizing published international HIA data, I look at who HIA researchers invite when they seek to get 'community input' in their HIA investigations. The HIA database was generated from an internet investigation of published HIAs (in English) from 1999 to 2011 and focused particularly on single authored assessments that were conducted by governments, non-governmental organizations (NGOs) or universities. HIA researchers access a wide range of emic and etic community perspectives in their search for the 'community's view'. Government, NGO and university investigators access community perspectives differently, with university HIA researchers inviting more emic-oriented community vistas than both government and NGO researchers. University and government HIA investigators are more likely to invite multiple emic and etic community perspectives during their community participation projects than NGO researchers. NGO HIA investigators tend to either invite emic perspectives or etic perspectives for their community input with less mixing of the two views in a single project. The paper concludes with a discussion on how HIA researchers can frame the 'community's perspective' in their HIA investigations through a combination of both 'insider' and 'outsider' community input sampling strategies.

    Full Text Available Lograr una arquitectura sustentable requiere, entre otros aspectos, incorporar consideraciones energéticas en etapas tempranas de los diseños arquitectónicos. Las definiciones ambientales involucran principalmente análisis numéricos y temporales, con un detalle de variables normalmente definidas en etapas avanzadas del trabajo proyectual, distantes de las resoluciones espaciales de la gestación inicial del diseño, especialmente durante el comienzo de la formación profesional. Se puede aplicar estos conocimientos técnicos en los alumnos, en etapas tempranas del proyecto, según las teorías de aprendizaje significativo y percepción, que sugieren capacidades de vinculación cognitiva, mediante tecnologías de información y simulaciones gráficas. Este artículo propone una secuencia de experiencias pedagógicas de integración, a partir de modelos para la resolución conjunta del diseño arquitectónico, que se enfoca en la elaboración de vistas espaciales graduadas según valores energéticos. Ello se ejemplifica con el dimensionamiento de vanos para iluminación natural en un recinto doméstico de trabajo, lo cual se relaciona con la privacidad y la visión exterior, como también con la comodidad y el consumo energético. El proceso se ensaya con grupos de estudiantes de arquitectura y a través de consultas con docentes y especialistas del área que reconocen una motivación significativa y de relación ambiental. Esta experiencia de integración gráfica implica una vinculación temprana de condiciones energéticas y espaciales, utilizable para la enseñanza y posterior desempeño profesional, que busca una arquitectura expresiva y ambientalmente responsable.

  16. New Vistas Open with MIDI at the VLT Interferometer

    2002-12-01

    "First Fringes" in Mid-Infrared Spectral Region with Two Giant Telescopes Summary Following several weeks of around-the-clock work, a team of astronomers and engineers from Germany, the Netherlands, France and ESO [2] has successfully performed the first observations with the MID-Infrared interferometric instrument (MIDI), a new, extremely powerful instrument just installed in the underground laboratory of the VLT Interferometer (VLTI) at the Paranal Observatory (Chile). In the early morning of December 15, 2002, two of the 8.2 m VLT unit telescopes (ANTU and MELIPAL) were pointed towards the southern star eta Carinae and the two light beams were directed via the complex intervening optics system towards MIDI. After a few hours of tuning and optimization, strong and stable interferometric fringes were obtained, indicating that all VLTI components - from telescopes to the new instrument - were working together perfectly. Two more stars were observed before sunrise, further proving the stability of the entire system. The first observations with MIDI mark one more important step towards full and regular operation of the VLT Interferometer [3] . They are a result of five years of determined efforts within a concerted technology project, based on a close collaboration between ESO and several European research institutes (see below). Now opening great research vistas, they also represent several "firsts" in observational astrophysics, together amounting to a real breakthrough in the field of astronomical interferometry . New views at mid-infrared wavelengths : MIDI is sensitive to light of a wavelength near 10 µm, i.e., in the mid-infrared spectral region ("thermal infrared"). This provides rich opportunities to study a wide range of otherwise inaccessible, crucial astrophysical phenomena, e.g., the formation of planets in dusty disks around newborn stars and the innermost regions around black holes. However, it is a great technical challenge to perform mid

    This paper is concerned with those studies and analyses that affected early NATO nuclear policy and force structure. The discussion focuses specifically on two open-quotes benchmarkclose quotes activities. Project VISTA and Project ATTACK. These two studies were chosen less because one can document their direct impact on NATO nuclear policy and more because they capture the state of thinking about tactical nuclear weapons at a particular point of time. Project VISTA offers an especially important benchmark in this respect. Project ATTACK is a rather different kind of benchmark. It is not a pathbreaking study. It is much narrower and more technical than VISTA. It appears to have received no public attention. Project ATTACK is interesting because it seems to capture a open-quotes nuts-and-boltsclose quotes feel for how U.S. (and thereby NATO) theater nuclear policy was evolving prior to MC 48. The background and context for Project VISTA and Project ATTACK are presented and discussed

    We investigated the ability to detect the articular disk and joint effusion of the temporomandibular joint (TMJ) of a method of dual echo volumetric isotropic turbo spin echo acquisition (DE-VISTA) additional fusion images (AFI). DE-VISTA was performed in the 26 TMJ of 13 volunteers and 26 TMJ of 13 patients. Two-dimensional (2D) dual echo turbo spin echo was performed in the 26 TMJ of 13 volunteers. On a workstation, we added proton density-weighted images (PDWI) and T 2 weighted images (T 2 WI) of the DE-VISTA per voxel to reconstruct DE-VISTA-AFI. Two radiologists reviewed these images visually and quantitatively. Visual evaluation of the articular disk was equivalent between DE-VISTA-AFI and 2D-PDWI. The sliding thin-slab multiplanar reformation (MPR) method of DE-VISTA-AFI could detect all articular disks. The ratio of contrast (CR) of adipose tissue by the articular disk to that of the articular disk itself was significantly higher in DE-VISTA-AFI than DE-VISTA-PDWI (P 2 WI but in only 3 of those joints in 2D-T 2 WI. The CR of joint effusion to adipose tissue on DE-VISTA-AFI did not differ significantly from that on DE-VISTA-PDWI. However, using DE-VISTA-T 2 WI in addition to DE-VISTA-PDWI, we could visually identify joint effusion on DE-VISTA-AFI that could not be identified on DE-VISTA-PDWI alone. DE-VISTA-AFI can depict the articular disk and a small amount of joint effusion by the required plane of MPR using the sliding thin-slab MPR method. (author)

    The radon is a radioactive gas. It occurs naturally in the atmosphere coming from the decay of radium, with emission of alpha particles. There are three radon isotopes more known, of which the most important under the environmental point of view is the Rn-222, whose half life is 3.82 days. The radon and their descendants are responsible by more than 40 % of the natural radioactive dose received for the human beings inside the building. In doses above 4 pCi/l, given as occupational dose, can cause among other diseases, the lung cancer. The main source of radon inside the building is the soil. The incidence of radon inside the building varies according to the soil composition, the materials employed in its construction, the inside air temperature and humidity, time during the day, season and the ventilation process designed. The work was realized at the commercial centers in Rio de Janeiro and Pocos de Caldas, for methodology confirmation. It was utilized the passive (track detectors) and active (two filters technique. Kusnetz technique, Tsivoglou technique and alpha spectrometry technique) methods. The objective of this work was to analyze the radon and thoron concentrations levels in order to supply parameters upon the quality of the air in those commercial centers. (author)

    The 'Culture and Memory of the Sto. Antonio do Morro Grande Quilombola Community' Program was included in the environmental licensing process of the Rio de Janeiro-Minas Gerais gas pipeline ('GASBEL II'), as requested by the Palmares Cultural Foundation (Fundacao Cultural Palmares), which stipulates the elaboration and implementation of this program as a condition for obtaining the installation license. To develop the program and submit it to this institution, we used methodological procedures in the form of an anthropological social research, such as: interviews with the community's older or most active residents, and a preliminary recognition of the territory and the local culture; all in order to learn more about the community's history and current needs and to identify the remaining 'quilombolas' still living in the community. Analyzing the information raised the need for guided actions designed to rescue the community's cultural memory as an ethnic group and to contribute to its process of affirmation as a Traditional Rural 'Quilombola' Community. This led to the creation of the proposed 'Culture and Memory of the Sto. Antonio do Morro Grande Quilombola Community' Program, currently being developed for the Quilombola Community located in Ressaquinha, in the State of Minas Gerais. (author)

    The June 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro has been planned more as a discussion of environment and development, rather than sustainable development as suggested by the 1987 World Commission on Environment and Development (the Brundtland Commission). The Canadian agenda for UNCED is like that of most of the developed countries, and focuses mainly on climatic change, deforestation, loss of biodiversity in the tropics, and health of the oceans. The agenda of the developing countries is based on the knowledge that most of these global problems have been caused or aggravated by the industrialized countries. The developing countries fear that actions imposed to solve environmental problems will threaten their economic development. A key demand from the developing countries is a commitment by developed countries to reduce their greenhouse gas emissions, leaving space for the developing countries to increase their emissions as they develop. There is little or no pressure on governments in the developed world to come to such a comprehensive deal. For Canada, much remains to be done in setting national priorities, and many of the issues to be discussed at UNCED are under provincial jurisdiction

    Full Text Available The Roraima viticulture began in 2003 with the creation of the Vale do Rio Branco project, in which the cultivation of grapes was enlarged for a commercial production. However, no information has been found in literature  about the mineral content of grapes produced. Considering the essentiality and importance of this information for human nutrition, quantification of species K by flame photometry and Ca, Fe and Zn by flame atomic absorption spectrometry in pulps of grapes of the Isabel, Vitis labrusca L. variety, cultivated in Boa Vista/RR has been realized, as well as determination of the physical characteristics of the grape bunches and berries. The determinations´ results indicate that K had the highest concentration, followed by Ca, Fe and Zn, being similar to the data, described in other literature sources, except for Ca, which showed smaller, indicating an intervention demand of culture methods employed to optimize the absorption of this species by vines. The consumption of Isabel grape can contribute to the achievement of the adequate intake recommendations of mineral elements. The results of the physical characterization let us classify Isabel grape bunches to very small, loose and green stalks. Overall, this study reveals new data about the physical characteristics and mineral composition present in Isabel grape grown in Boa Vista/RR.

    The 'Energy 2010-2020' group from the French general survey commission has carried out a two-years study for the forecasting of the evolution of the French energy consumption from today up to the year 2020. Three scenarios were considered which correspond to contrasted policies and behaviours of the economical agents: market competition (S1), increased participation of public authorities in industrial and economic policies (S2), environmental protection priority (S3). Identical macro-economical basic hypotheses were used in all scenarios to determine: the annual growth rate of automotive fuel taxes, the sectoral analysis of energy consumption (industry, residential, agriculture, transports), the primary energy consumption (solid mineral fuels, petroleum, natural gas, electricity, renewable energies), market shares and national production. Three questions remain to be clarified: are the scenarios too optimistic? How to evaluate the security of supplies? And how to carry out our engagements concerning the emissions of greenhouse gases?

  10. The VISTA spacecraft: Advantages of ICF [Inertial Confinement Fusion] for interplanetary fusion propulsion applications

    International Nuclear Information System (INIS)

    Orth, C.D.; Klein, G.; Sercel, J.; Hoffman, N.; Murray, K.; Chang-Diaz, F.

    1987-01-01

    Inertial Confinement Fusion (ICF) is an attractive engine power source for interplanetary manned spacecraft, especially for near-term missions requiring minimum flight duration, because ICF has inherent high power-to-mass ratios and high specific impulses. We have developed a new vehicle concept called VISTA that uses ICF and is capable of round-trip manned missions to Mars in 100 days using A.D. 2020 technology. We describe VISTA's engine operation, discuss associated plasma issues, and describe the advantages of DT fuel for near-term applications. Although ICF is potentially superior to non-fusion technologies for near-term interplanetary transport, the performance capabilities of VISTA cannot be meaningfully compared with those of magnetic-fusion systems because of the lack of a comparable study of the magnetic-fusion systems. We urge that such a study be conducted

    Observations of very small changes of Earth’s gravitational field (time-lapse gravity) provide a direct, non-invasive method for measuring changes in aquifer storage change. An existing network of gravity stations in the Sierra Vista Subwatershed was revised in 2014 to better understand the spatial distribution of changes in aquifer storage, especially with relation to ephemeral channel recharge and a groundwater cone of depression associated with pumping in the greater Sierra Vista area. In addition, the network was extended to provide baseline data for possible future enhanced-recharge projects.

    2016-09-01

    The recent Paris Agreement to limit greenhouse gas emissions, adopted by 195 nations at the 2015 United Nations Climate Change Conference, signaled unprecedented commitment by world leaders to address the human social aspects of climate change. Indeed, climate change increasingly is recognized by scientists and policymakers as a social issue requiring social solutions. However, whereas psychological research on intrapersonal and some group-level processes (e.g., political polarization of climate beliefs) has flourished, research into other social processes-such as an understanding of how nonpartisan social identities, cultural ideologies, and group hierarchies shape public engagement on climate change-has received substantially less attention. In this article, we take stock of current psychological approaches to the study of climate change to explore what is "social" about climate change from the perspective of psychology. Drawing from current interdisciplinary perspectives and emerging empirical findings within psychology, we identify four distinct features of climate change and three sets of psychological processes evoked by these features that are fundamentally social and shape both individual and group responses to climate change. Finally, we consider how a more nuanced understanding of the social underpinnings of climate change can stimulate new questions and advance theory within psychology. © The Author(s) 2016.

  15. A vista of new knowledge from ESA's Hipparcos astronomy mission

    Science.gov (United States)

    1997-05-01

    Hipparcos is a milestone in the history of astronomy. In 1985 the American physicist Freeman J. Dyson hailed Hipparcos as the first major new development in space science to come from outside the United States. The spacecraft operated in orbit 1989-93, measuring the angles between stars in the sky. Over a further three years, computing teams across Europe generated a consistent, high-precision plot of 118,000 stars in the Hipparcos Catalogue and somewhat less accurate (but still unprecedented) data on a million stars in the Tycho Catalogue. The distances, motions, pairings and variability of stars are now known far more accurately than ever before. Hipparcos will make an impact on every branch of astronomy, from the Solar System to the history of the Universe, and especially on theories of stars and their evolution. For almost a year, astronomers most closely associated with the mission have had an early view of the completed catalogues and in Venice they will summarize their initial results. The Hipparcos data will be published in June, as an extraordinary contribution from Europe to astronomy all around the world. The success of Hipparcos has created problems for the organizers of Venice symposium. Altogether 190 scientific papers were offered for presentation by various groups of astronomers. With three mornings and three afternoons available for the main scientific sessions, 67 oral presentations are accommodated, by restricting speakers to 10-15 minutes each. For the rest, there will a generous display of results in the form of posters. Thus Hipparcos will be celebrated by a vista of new knowledge. The stars are looking younger Already Hipparcos seems to cure a headache concerning the ages of stars. As recently as last year, astronomers were perplexed by a contradiction between their estimates of the age of the Universe, and stars that seemed to be older. An early Hipparcos result announced in February 1997 (ESA Information Note 04/97) concerned the winking

    Full Text Available Abstract Background Many readers will sympathize with the following story. You are viewing a gene sequence in Entrez, and you want to find whether it contains a particular sequence motif. You reach for the browser's "find in page" button, but those darn spaces every 10 bp get in the way. And what if the motif is on the opposite strand? Subsequently, your favorite sequence analysis software informs you that there is an interesting feature at position 13982–14013. By painstakingly counting the 10 bp blocks, you are able to examine the sequence at this location. But now you want to see what other features have been annotated close by, and this information is buried several screenfuls higher up the web page. Results SeqVISTA presents a holistic, graphical view of features annotated on nucleotide or protein sequences. This interactive tool highlights the residues in the sequence that correspond to features chosen by the user, and allows easy searching for sequence motifs or extraction of particular subsequences. SeqVISTA is able to display results from diverse sequence analysis tools in an integrated fashion, and aims to provide much-needed unity to the bioinformatics resources scattered around the Internet. Our viewer may be launched on a GenBank record by a single click of a button installed in the web browser. Conclusion SeqVISTA allows insights to be gained by viewing the totality of sequence annotations and predictions, which may be more revealing than the sum of their parts. SeqVISTA runs on any operating system with a Java 1.4 virtual machine. It is freely available to academic users at http://zlab.bu.edu/SeqVISTA.

  5. Project Rio Blanco: site restoration. Final report

    International Nuclear Information System (INIS)

    1978-01-01

    Project Rio Blanco was a joint Government-industry experiment using nuclear explosives to stimulate the flow of natural gas from low permeability formations which could not be economically produced through conventional methods. The project consisted of the simultaneous detonation of three nuclear explosives on May 17, 1973, in a 7,000 foot well in northwestern Colorado. Gas production testing and project evaluation continued through June 1976. The site cleanup and restoration planning phase began in December 1975 and was concluded with the issuance of an operational plan, Project Rio Blanco Site Cleanup and Restoration Plan, NVO-173, in May 1976. Actual site restoration activities were conducted during the period from July to November 1976. The activities throughout the restoration period are summarized and the final site status, including the disposition of all project facilities and the status of all project related wells after plug and abandonment and recompletion work are described

    Full Text Available The Permo-Triassic archosauromorph record is crucial to understand the impact of the Permo-Triassic mass extinction on the early evolution of the group and its subsequent dominance in Mesozoic terrestrial ecosystems. However, the Permo-Triassic archosauromorph record is still very poor in most continents and hampers the identification of global macroevolutionary patterns. Here we describe cranial and postcranial bones from the Permo-Triassic Buena Vista Formation of northeastern Uruguay that contribute to increase the meagre early archosauromorph record from South America. A basioccipital fused to both partial exoccipitals and three cervical vertebrae are assigned to Archosauromorpha based on apomorphies or a unique combination of characters. The archosauromorph remains of the Buena Vista Formation probably represent a multi-taxonomic assemblage composed of non-archosauriform archosauromorphs and a ‘proterosuchid-grade’ animal. This assemblage does not contribute in the discussion of a Late Permian or Early Triassic age for the Buena Vista Formation, but reinforces the broad palaeobiogeographic distribution of ‘proterosuchid grade’ diapsids in Permo-Triassic beds worldwide.

    2004-09-01

    VISTA (Visible and Infrared Survey Telescope for Astronomy) is designed to be the world's largest wide field telescope. After finishing of the construction the telescope will be part of ESO and located in Chile close to the VLT observatory at Cerro Paranal. In November 2001 SCHOTT was selected by the VISTA project office at the Royal Observatory of Edinburgh to deliver the 4.1 m diameter primary mirror blank. The manufacturing of the mirror blank made from the zero expansion material Zerodur was challenging especially due to the f/1 design. Several tons of the glass ceramic material were removed during the grinding operation. A meniscus blank with a diameter of 4100 mm and a thickness of 171.5 mm was generated, having a large central hole of 1200 mm and an aspherical shape of the concave surface. Also the handling and turning operations needed special effort and were performed by a skilled team. This paper presents details and pictures of the corresponding production and inspection sequence at SCHOTT. The geometrical parameters were measured during manufacturing by help of a laser tracker system and the achieved parameters were compared with the initial technical specification. The final quality inspection verified the excellent quality of the mirror blank. The close co-operation between the astronomers and industry resulted in a project management without problems. In April 2003 the VISTA blank was delivered successfully within a ceremony dedicated to the anniversary of "100 years of astronomical mirror blanks from SCHOTT."

    Full Text Available Production of the watermelon is important in all regions of Brazil. However, productive and qualitative information for fruit of different cultivars grown in the same environment is still scarce, especially in the State of Roraima, a fact that makes it necessary to carry out studies in order to meet this need. As a result, this study aimed to evaluate the agronomic performance of watermelon cultivars produced in the Cerrado at Boa Vista, Roraima. The experiment was conducted at the Agua Boa Experimental Farm of Embrapa Roraima, from December 2013 to February 2014. The experimental design was of randomised blocks (DBC, with six replications. The treatments comprised six watermelon cultivars: Verena, Explore, Elisa, Juliane, Crimson Sweet and Crimson Sweet Super, for which the productive, physical, chemical and physicochemical characteristics of the fruit were evaluated. There was no difference between cultivars in yield, number of fruit ha-1 or the number of fruit with a weight of between 6 and 9 kg. The cultivars differed as to physical characteristics (weight, size and number of seeds per fruit. There were differences between cultivars for all the chemical and physicochemical characteristics of the fruit. The cultivar Elisa displayed the highest levels for total soluble solids (12.58 °Brix. Fruits of the cultivars Explore and Crimson Sweet Super showed the greatest ratio between total soluble solids and titratable acidity. The fruits of the cultivars Explore and Elisa had the highest pH. The conditions of soil and climate in the Cerrado at Boa Vista favour the productive and qualitative characteristics of the cultivars being analysed. = A produção de melancia é consolidada em todas as regiões do Brasil. Porém, as informações sobre produtividade e qualidade dos frutos, de diferentes cultivares no mesmo ambiente, ainda são tímidas, sobretudo em Roraima, tornando necessária a realização de estudos para suprir essa carência.

    The purpose of this study was to evaluate the radiological procedures used at the odontologic clinics of Boa Vista, Roraima-Brazil. The following parameters were recorded: field diameter, half value layer, total filtration, discrepancy between the preset and the applied kilovoltage and exposure time. Dose to the patient's skin from radiography of the upper molar tooth was also estimated. The results showed that 78% of the inspected units had field diameters larger than 6,0 cm, which is outside the limits recommended by the Brazilian Health Ministry. The results also showed that 14% of the equipment presented a discrepancy of more than 10% between preset and applied kilovoltage. On the other hand, the discrepancy between preset and applied exposure time is higher than 10% in 70% of the tested units. The total filtration of 77% units is lower than 1,5 mm of Al, a value recommended by the Brazilian Health Ministry for equipment that operates in the range of 50 kV to 70 kV. The survey also indicates that for 35% of the units the entrance dose in high than 3,5 mGy that is the reference value established by the Brazilian Health Ministry for dental radiography with film type. It was observed that the majority of the clinics use neither aprons nor collars for patients and that films are processed manually, without controlling temperature or processing time. Based on the results obtained it is strongly recommended that a quality control program be implemented in dental radiological clinics in Boa Vista, Roraima. (author)

    Full Text Available A produção literária de Simone de Beauvoir marca-se pelo seu caráter acentuadamente autobiográfico. E também por manter aí um constante diálogo com o seu companheiro Sartre. Sob esta perspectiva, A Cerimônia do Adeus (1981, que relata os dez últimos anos de vida de Sartre, apresenta uma estrutura narrativa curiosa: propõe-se como um diário, mas do outro, pois a narradora tenta anular-se em favor da reconstrução de um retrato de Sartre. No entanto, por injunção desta proposta, inviável, o texto acaba transformando-se num ponto de convergência de vários gêneros narrativos, tendo em vista o caráter múltiplo de personalidade do biografado. E este personalizado trabalho narrativo, à revelia da própria autora, acarreta o processo inverso: o texto transforma-se num retrato de Simone. Consuma-se, desta forma, no próprio corpo do texto, o movimento de sedução, em que ambos, homem e mulher, realizam-se como sujeitos necessários Um ao Outro.L'oeuvre de Simone de Beauvoir est marquée par son caractère fortemente autobiographique, aussi bien que par le dialogue constante avec son partenaire Sartre. Sous une telle optique, La Cérémonie des Adieux (1981, qui raconte les dix dernières années de la vie de Sartre, présente une structure narrative curieuse: le livre se présente comme un journal, mais le journal de l'autre, puisque la narratrice essaie de s'effacer face à la reconstruction d'un portrait de Sartre. Pourtant, à cause de cet objectif inacessible, le texte finit par devenir un point de convergence de plusieurs genres de récit, étant donné le caractère multiple de la personnalité du sujet de la biographie. Ce travail narratif personnalisé va entraîner le processus inverse, malgré son auteur même: le récit devient un portrait de Simone. Ainsi, c'est dans le corps même du texte qu'a lieu le mouvement de séduction où homme et femme se réalisent comme sujets indispensables l'Un à l'Autre.

    1992-12-01

    Geographic information system (GIS) applications for the siting and monitoring of gas pipeline rights-of-way (ROWS) were developed for areas near Rio Vista, California. The data layers developed for this project represent geographic features, such as landcover, elevation, aspect, slope, soils, hydrography, transportation, endangered species, wetlands, and public line surveys. A GIS was used to develop and store spatial data from several sources; to manipulate spatial data to evaluate environmental and engineering issues associated with the siting, permitting, construction, maintenance, and monitoring of gas pipeline ROWS; and to graphically display analysis results. Examples of these applications include (1) determination of environmentally sensitive areas, such as endangered species habitat, wetlands, and areas of highly erosive soils; (2) evaluation of engineering constraints, including shallow depth to bedrock, major hydrographic features, and shallow water table; (3) classification of satellite imagery for landuse/landcover that will affect ROWS; and (4) identification of alternative ROW corridors that avoid environmentally sensitive areas or areas with severe engineering constraints.

    Dimension Vista® analyzer combines four technologies (photometry, nephelometry, V-LYTE® integrated multisensor potentiometry, and LOCI® chemiluminescence) into one high-throughput system. We assessed analytical performance of assays routinely performed in our emergency laboratory according to the VALTEC protocol, and practicability. Precision was good for most parameters. Analytical domain was large and suitable for undiluted analysis in most clinical settings encountered in our hospital. Data were comparable and correlated to our routine analyzers (Roche Modular DP®, Abbott AXSYM®, Siemens Dimension® RxL, and BN ProSpec®). Performance of nephelometric and LOCI modules was excellent. Functional sensitivity of high-sensitivity C-reactive protein and cardiac troponin I were 0.165 mg/l and 0.03 ng/ml, respectively (coefficient of variation; CV < 10%). The influence of interfering substances (i.e., hemoglobin, bilirubin, or lipids) was moderate, and Dimension Vista® specifically alerted for interference according to HIL (hemolysis, icterus, lipemia) indices. Good instrument performance and full functionality (no reagent or sample carryover in the conditions evaluated, effective sample-volume detection, and clot detection) were confirmed. Simulated routine testing demonstrated excellent practicability, throughput, ease of use of software and security. Performance and practicability of Dimension Vista® are highly suitable for both routine and emergency use. Since no volume detection and thus no warning is available on limited sample racks, pediatric samples require special caution to the Siemens protocol to be analyzed in secured conditions. Our experience in routine practice is also discussed, i.e., the impact of daily workload, "manual" steps resulting from dilutions and pediatric samples, maintenances, flex hydration on instrument's performance on throughput and turnaround time. © 2012 Wiley Periodicals, Inc.

    As the SMART plant was designed with the helical type tubes in the steam generators, the heat transfer model in that geometry has been implemented in the TASS/SMR-S code and used for the safety analysis. The same correlation was implemented in the MIDAS/SMR, which is being used for the severe accident analyses, to model heat transfer at the steam generators. In this study, the VISTA SG experiment with the helical steam generator tube was simulated with MIDAS/SMR to compare the heat transfer rates through the helical tube

    Traveltime measurements were made during 2006 and 2007 along the Truckee River between Tahoe City, Calif., and Vista, Nev. Fluorescent rhodamine WT dye was injected at various locations along the river during streamflows ranging from 143 to 2,660 cubic feet per second. The resulting data, presented in tabular and graphic form, may be useful to water-quality modelers or water-resources managers concerned with predicting the movement of soluble contaminants accidentally spilled into the Truckee River. The data provided in this report also could be used to determine the dispersion-related characteristics (duration and magnitude of pollutant concentrations) that may be expected in the Truckee River.

    One way to reduce the effects of anthropogenic greenhouse gases on climate is to inject carbon dioxide (CO 2 ) from industrial sources into deep geological formations such as brine aquifers or depleted oil or gas reservoirs. Research is being conducted to improve understanding of factors affecting particular aspects of geological CO 2 storage (such as storage performance, storage capacity, and health, safety and environmental (HSE) issues) as well as to lower the cost of CO 2 capture and related processes. However, there has been less emphasis to date on system-level analyses of geological CO 2 storage that consider geological, economic, and environmental issues by linking detailed process models to representations of engineering components and associated economic models. The objective of this study is to develop a system-level model for geological CO 2 storage, including CO 2 capture and separation, compression, pipeline transportation to the storage site, and CO 2 injection. Within our system model we are incorporating detailed reservoir simulations of CO 2 injection into a gas reservoir and related enhanced production of methane. Potential leakage and associated environmental impacts are also considered. The platform for the system-level model is GoldSim [GoldSim User's Guide. GoldSim Technology Group; 2006, http://www.goldsim.com]. The application of the system model focuses on evaluating the feasibility of carbon sequestration with enhanced gas recovery (CSEGR) in the Rio Vista region of California. The reservoir simulations are performed using a special module of the TOUGH2 simulator, EOS7C, for multicomponent gas mixtures of methane and CO 2 . Using a system-level modeling approach, the economic benefits of enhanced gas recovery can be directly weighed against the costs and benefits of CO 2 injection

    Royalties and the windfall profits tax derived from petroleum exploration and production in Brazil are government take with huge impacts on the financial health of the state and cities of Rio de Janeiro. Considering the relevance of oil revenue, this study evaluates the significance of the amount transferred between government levels, comparing the current allocation system with international cases. The implemented methodology to reach the result has been the evaluation and data analysis, based on the finances of the state of Rio de Janeiro and the cities that have common borders with the Campos Basin. Furthermore, international cases have been analyzed. Findings indicate that, on one hand, the centralization of the oil revenue at federal level guarantees a better capacity to absorb uncertainties and the variation on the amount received; on the other hand, under a local level, it's possible to identify and better supply the local necessities and scarcities, not to mention, realize a more effective control. In the Brazilian case, this point is even more relevant, as far as debate concerning the distribution of government take cannot be done without considering a broader tax reform, especially in the case of petroleum, which should be associated with the incidence of ICMS on the destination.(author)

    A minimum 4-point change at 6 months on the Alzheimer's disease assessment scale-cognitive subscale (ADAS-cog) is deemed clinically important, but this cut-point has been little studied in relation to clinical meaningfulness. In an investigator-initiated, clinical trial of galantamine, we investigated the extent to which a 4-point change classifies goal attainment by individual patients. Secondary analysis of the video imaging synthesis of treating Alzheimer's disease (VISTA) study: a 4-month, multi-centre, parallel-group, double-blind, placebo-controlled, trial of galantamine in 130 mild-moderate Alzheimer's disease patients (4-month open-label follow-up). ADAS-cog responses at 6 months were compared with outcomes on three clinical measures: clinician's interview based impression of change-plus caregiver input (CIBIC+), patient/carer-goal attainment scaling (PGAS) and clinician-GAS (CGAS). Thirty-seven of 99 patients improved by > or = 4 points on the ADAS-cog at 6 months, and 16/99 showed > or = 4-point worsening. ADAS-cog change scores correlated notionally to modestly with changes on the CGAS (r = -0.31), the PGAS (r = -0.29) and the CIBIC+ (r = 0.31). As a group, patients with ADAS-cog improvement were significantly more likely to improve on the clinical measures; those who worsened showed non-significant clinical decline. Individually, about half were misclassified in relation to each clinical measure; often when the ADAS-Cog detected 'no change', clinically meaningful effects could be detected. Even so, no ADAS-Cog cut-point optimally classified patients' clinical responses. A 4-point ADAS-cog change at 6 months is clinically meaningful for groups. Substantial individual misclassification between the ADAS-cog and clinical measures suggests no inherent meaning to a 4-point ADAS-cog change for a given patient.

    A thermal-hydraulic integral effect test facility, VISTAITL, for the SMART design has been constructed by the Korea Atomic Energy Research Institute (KAERI). The VISTA-ITL has the simulation capability of small break loss of coolant accident (SBLOCA), passive residual heat removal system (PRHRS) performance, and complete loss of RCS (Reactor Coolant System) flowrate (CLOF), etc. The VISTA-ITL is a 1/2.77- height and 1/1310-volume scaled test facility based on the design features of SMART. The reference scale ratios of length (1/2.77) and area (1/472.9) are based on the elevation difference between the core and steam generator centers and the core flow area, respectively. According to the scaling law, the reduced height scaling results in time reducing results in the model and the time scale ratio is 1/1.664. Three SBLOCA tests of safety injection system (SIS) line break, shutdown cooling system (SCS) line break and pressurizer safety valve (PSV) line break were successfully performed and its major results have been compared and discussed in this paper

Replantea la tesis de Joseph Raz de que, para proferir enunciados descriptivos tales, debe adoptarse hipotéticamente el punto de vista jurídico, en sí mismo moralmente comprometido; según esa tesis, una ciencia jurídica acorde a las exigencias ha de pronunciarse profiriendo enunciados de un tipo que Raz denomina “no comprometidos”. El texto aborda varias posturas críticas contra esta visión y muestra que si bien es posible rechazar la tesis de Raz tal como la postula, se corre el peligro de descartar como no problemático más de lo plausiblemente descartable.

    The Secretary-General of the UN Conference on Environment and Development notes that after the Earth Summit in Rio de Janeiro discussions about the environment and development will differ from those prior to the Summit. These discussions must now incorporate problems of developing countries, poverty, inequalities, flow of resources to developing countries, and terms of trade. The Rio Declaration on Environment and Development consists of important tenets, but it must evolve into an Earth Charter to be endorsed on the 50th anniversary of the UN in 1965. The Summit's Plan of Action, Agenda 21, must also continue to evolve and, despite its shortcomings, is the most extensive and, if implemented, most effective international action ever approved by the international community. Financing the Agenda 21 initiatives remains to be decided. New possible sources of funding must be based n the polluter pays principle and may include new taxes, user charges, emission permits, and citizen funding. Even though the most serious problem in the 1990s is stabilization of atmospheric gases, the Rio agreement does not include targets or timetables. Governments must take united action immediately to reduce carbon dioxide emissions by at least 60%. 1 nation has not yet approved the convention on biological diversity. Governments also need to move forward on conventions on decertification and deforestation. They need to incorporate the global objectives of Agenda 21 into their own national policies and practices. This must also be done at the global, regional, organizational, local, and individual levels. The global community must also begin technology capacity building. The participatory process should also include nongovernmental organizations. Population growth must also slow dramatically to achieve sustainable development. The various participatory levels must consider elimination of poverty.

    1975-01-01

    Rio Blanco was the third experiment in the U.S. Atomic Energy Commission's Plowshare Program to develop technology to stimulate gas production from geologic formations not conducive to production by conventional means. The project was sponsored by CER Geonuclear Corporation, with the Lawrence Livermore Laboratory providing the explosives and several technical programs, such as spall measurement. Three nuclear explosives specifically designed for this application were detonated simultaneously in a minimum-diameter emplacement well using many commercially available but established-reliability components. The explosive system performed properly under extreme temperature and pressure conditions. Emplacement and stemming operations were designed with the aim of simplifying both the emplacement and reentry and fully containing the detonation products. An integrated command and control system was used with communication to all three explosives through a single coaxial cable. Reentry and the initial production testing are completed. To date 98 million standard ft 3 of chimney gas have been produced. (auth)

    Ancient Maya ports along the largely unstudied northeast coast of the Yucatan Peninsula once supported a network of trade routes linking people, goods, and ideas from across Mesoamerica. The Costa Escondida Project has focused on the interrelationships between the ancient Maya and their dynamic coastal environment along the shores of the Laguna Holbox. Central to our interdisciplinary efforts is a paleoenvironmental and paleoecological reconstruction of the key port of Vista Alegre - a low-lying island surrounded by a complex mosaic of costal ecosystems, sedimentological facies, and hydrological conditions. Geoarchaeological field methods, such as sediment coring, have made possible multiproxy analyses that enable us to better understand sea level fluctuations and the morphology of the shoreline and harboring locations over time, as well as changes in ecosystem biodiversity, which would have presented the maritime Maya with unique challenges and opportunities.

    Sequence stratigraphy is a newly developed subject based on seismostratigraphy, and has been widely applied in the exploration of hydrocarbon and other sedimentogenic mineral deposits and great achievements have been obtained. However, the application of sequence stratigraphy to the exploration of sandstone-hosted uranium deposits is just at the beginning. In this paper, some primary research achievements of sequence stratigraphy to the exploration of sandstone-hosted uranium deposits are summarized, and problems and their reasons of the application of sequence stratigraphy are discussed. Further more, according to characteristics of sandstone-hosted uranium deposits and the development of sequence stratigraphy, the application vistas of sequence stratigraphy to the exploration of sandstone-hosted uranium deposits are estimated. Finally, application directions are proposed, and some specific suggestions are given. (authors)

    Full Text Available Uno de los procedimiento narrativos más interesantes consiste en mostrar dos o más veces en el discurso un acontecimiento que ha tenido lugar una sola vez en la historia (frecuencia repetitiva pero variando el punto de vista de forma que en cada una de las ocasiones se muestren diferentes aspectos de un mismo acontecimiento para que el sentido final sea distinto. Normalmente, en la primera ocasión en que se muestra hay una falta de información que puede provocar un enigma en el espectador. En otras ocasiones, la frecuencia repetitiva se utiliza para modificar el sentido de un acontecimiento introduciendo nuevos datos. Para controlar el suministro informativo se suele recurrir  a la elipsis y al espacio fuera de campo. A través de la elipsis se elimina un dato fundamental, mientras que el espacio fuera de campo oculta un dato esencial para comprender el acontecimiento.

    Light that is emitted from distant quasars can become partially absorbed by intervening gaseous structures, including galaxies, in its path toward Earth, revealing information about the chemical content, degree of ionization, organization and evolution of these structures through time. In this project, quasar spectra are used to probe the halos of foreground galaxies at a mean redshift of z=1.1 in the COSMOS Field. Mg II absorption lines in Sloan Digital Sky Survey quasar spectra are paired with galaxies in the UltraVISTA catalog at an impact parameter less than 200 kpc. A sample of 77 strong Mg II absorbers with a rest-frame equivalent width ≥ 0.3 Å and redshift from 0.34 < z < 2.21 are investigated to find equivalent width ratios of Mg II, C IV and Fe II absorption lines, and their relation to the impact parameter and the star formation rates, stellar masses, environments and redshifts of their host galaxies.

    The purpose of this study was to evaluate the radiological procedures used at the odontologic clinics of Boa Vista, Roraima-Brazil. The following parameters were recorded: field diameter, half value layer, total filtration, discrepancy between the preset and the applied kilovoltage and exposure time. Dose to the patient's skin from radiography of the upper molar tooth was also estimated. The results showed that 78% of the inspected units had field diameters larger than 6,0 cm, which is outside the limits recommended by the Brazilian Health Ministry. The results also showed that 14% of the equipment presented a discrepancy of more than 10% between preset and applied kilovoltage. On the other hand, the discrepancy between preset and applied exposure time is higher than 10% in 70% of the tested units. The total filtration of 77% units is lower than 1,5 mm of Al, a value recommended by the Brazilian Health Ministry for equipment that operates in the range of 50 kV to 70 kV. The survey also indicates that for 35% of the units the entrance dose in high than 3,5 mGy that is the reference value established by the Brazilian Health Ministry for dental radiography with film type. It was observed that the majority of the clinics use neither aprons nor collars for patients and that films are processed manually, without controlling temperature or processing time. Based on the results obtained it is strongly recommended that a quality control program be implemented in dental radiological clinics in Boa Vista, Roraima. (author)

    Full Text Available David Roberts' views of Córdoba were carried out in 1833 and later redrafted as lithographs, engravings, and oils. These artworks enjoyed great commercial success and international diffusion due to their thematic and undoubted artistic value. The authors analyze their documentary value as a graphic record -prior to the advent of photography- of the urban landscape and architecture of Cordoba, a city now denominated a World Heritage Site. These images are studied here for the first time as a group, since they are either virtually untraceable or dispersed in museums throughout the world. In addition, these views have been contextualized with information concerning the artist and his Spanish journey, including a letter that he wrote from Córdoba. The documentary reliability of every image is also assessed, while the significant transformations of the places represented are indicated.Las vistas realizadas en Córdoba por David Roberts en 1833, reelaboradas como litografías, grabados y óleos, han gozado de gran éxito comercial y difusión internacional por su temática e indudable interés artístico.

Las imágenes presentadas se analizan por primera vez como conjunto, pues algunas son de difícil localización o están dispersas en museos de todo el mundo, y se contextualizan con datos sobre el pintor y su viaje por España, considerando una carta que éste escribió desde Córdoba. También se valora la fiabilidad documental de cada vista, a la vez que se detectan significativas transformaciones de los lugares representados.

Con los métodos de enseñanza tradicionales se procura formar habilidades en este campo, pero no se afianzan mediante la práctica que, generalmente, se emplea para el aprendizaje en este campo. Por ello, en este artículo se propone ''PoV-GAME'', una nueva forma de ''jugar aprendiendo'', la cual busca fortalecer algunos conceptos básicos en la ingeniería de software como la consistencia en la información que se maneja a lo largo de un proyecto y afianzar la importancia de los puntos de vista en el desarrollo de un producto de software. Posteriormente, se analizan los resultados obtenidos luego de realizar el juego en diferentes grupos de estudiantes.Information for software applications is delivered by the stakeholders. Software development projects need consistency as an important aspect of such information. In other words, agreement among the different viewpoints must be reached in order to be implemented in the project. Well-known teaching methods try to create capabilities in this field, but they fail in reinforcing them in practice, which is commonly used for teaching in this field. Therefore, in this paper we propose ''PoV GAME'' a new way of ''play-to-learn''. We aim the reinforcement of some basic concepts about software engineering such as consistency in the information handled throughout the project, and the importance of viewpoints in the software product development. Subsequently, we analyze the results obtained after holding the game in several groups of students.

    The untold story of the Maritime Maya from the ancient port site Vista Alegre, is being written for the first time using a multidisciplinary effort that aims to reconstruct the environmental and morphological history of the site. Vista Alegre is located on the north-eastern tip of the Yucatan peninsula, on the ancient Maritime Maya trade routes. This strategic point between the Caribbean Sea and the Gulf of Mexico, offers an ideal setting for this kind of research, which will add to the general Maritime Maya history. The multidisciplinary effort is part of a larger project called "Costa Escodida". The project's main goals are to learn how the ancient inhabitants adapted to the environment, and to understand how this coastal site was integrated into broader maritime trade routes. The portion of the research presented here concentrates on the sites geomorphology and climate during the past 2-3000 years through the multiproxy analysis of marine sediment core and surface samples combined with archaeological data. This study aids our understanding of the site's possible functions, the environmental challenges the local inhabits contended with, and the identification of ancient harboring locations. The site was inhabited from the 9th century B.C until the mid 16th century A.D., with an apparent two century abandonment phase from the mid 7th to 9th century A.D. According to the results, five depositional phases can be recognized, and the related shoreline reconstruction shows a general trend of a flooded terrestrial landscape. This 'flooding' relates well to relative sea-level curves published in the region. Continued analysis of results from the research, and future research activities, may make it possible to recognize hurricane proxies in the sediment, locate underwater manmade seafaring artifacts and facilities, determine the range of economic opportunities for past inhabitants and quantify the availability of potable water sources.

  8. Rio Blanco massive hydraulic fracture: project definition

    International Nuclear Information System (INIS)

    1976-01-01

    A recent Federal Power Commission feasibility study assessed the possibility of economically producing gas from three Rocky Mountain basins. These basins have potentially productive horizons 2,000 to 4,000 feet thick containing an estimated total of 600 trillion cubic feet of gas in place. However, the producing sands are of such low permeability and heterogeneity that conventional methods have failed to develop these basins economically. The Natural Gas Technology Task Force, responsible for preparing the referenced feasibility study, determined that, if effective well stimulation methods for these basins can be developed, it might be possible to recover 40 to 50 percent of the gas in place. The Task Force pointed out two possible underground fracturing methods: Nuclear explosive fracturing, and massive hydraulic fracturing. They argued that once technical viability has been demonstrated, and with adequate economic incentives, there should be no reason why one or even both of these approaches could not be employed, thus making a major contribution toward correcting the energy deficiency of the Nation. A joint Government-industry demonstration program has been proposed to test the relative effectiveness of massive hydraulic fracturing of the same formation and producing horizons that were stimulated by the Rio Blanco nuclear project

    Context. Globular clusters (GCs) are key to our understanding of the Universe, as laboratories of stellar evolution, fossil tracers of the past formation epoch of the host galaxy, and effective distance indicators from local to cosmological scales. Aim. We analyze the properties of the sources in the NGC 253 with the aim of defining an up to date catalog of GC candidates in the galaxy. Given the distance of the galaxy, GCs in NGC 253 are ideal targets for resolved color-magnitude diagram studies of extragalactic GCs with next-generation diffraction limited ground-based telescopes. Methods: Our analysis is based on the science verification data of two ESO survey telescopes, VST and VISTA. Using ugri photometry from VST and JKs from VISTA, GC candidates were selected using as reference the morpho-photometric and color properties of spectroscopically confirmed GCs available in the literature. The strength of the results was verified against available archival HST/ACS data from the GHOSTS survey: all but two of the selected GC candidates appear as star clusters in HST footprints. Results: The adopted GC selection leads to the definition of a sample of ˜350 GC candidates. At visual inspection, we find that 82 objects match all the requirements for selecting GC candidates and 155 are flagged as uncertain GC candidate; however, 110 are unlikely GCs, which are most likely background galaxies. Furthermore, our analysis shows that four of the previously spectroscopically confirmed GCs, i.e., ˜20% of the total spectroscopic sample, are more likely either background galaxies or high-velocity Milky Way stars. The radial density profile of the selected best candidates shows the typically observed r1/4-law radial profile. The analysis of the color distributions reveals only marginal evidence of the presence of color bimodality, which is normally observed in galaxies of similar luminosity. The GC luminosity function does not show the typical symmetry, mainly because of the lack

Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

  15. VISTA -- A Vehicle for Interplanetary Space Transport Application Powered by Inertial Confinement Fusion

    Energy Technology Data Exchange (ETDEWEB)

    Orth, C D

    2005-03-31

    Inertial Confinement Fusion (ICF) is an ideal technology to power self-contained single-stage piloted (manned) spacecraft within the solar system because of its inherently high power/mass ratios and high specific impulses (i.e., high exhaust velocities). These technological advantages are retained when ICF is utilized with a magnetic thrust chamber, which avoids the plasma thermalization and resultant degradation of specific impulse that are unavoidable with the use of mechanical thrust chambers. We started with Rod Hyde's 1983 description of an ICF-powered engine concept using a magnetic thrust chamber, and conducted a more detailed systems study to develop a viable, realistic, and defensible spacecraft concept based on ICF technology projected to be available in the first half of the 21st century. The results include an entirely new conical spacecraft conceptual design utilizing near-existing radiator technology. We describe the various vehicle systems for this new concept, estimate the missions performance capabilities for general missions to the planets within the solar system, and describe in detail the performance for the baseline mission of a piloted roundtrip to Mars with a 100-ton payload. For this mission, we show that roundtrips totaling {ge}145 days are possible with advanced DT fusion technology and a total (wet) spacecraft mass of about 6000 metric tons. Such short-duration missions are advantageous to minimize the known cosmic-radiation hazards to astronauts, and are even more important to minimize the physiological deteriorations arising from zero gravity. These ICF-powered missions are considerably faster than those available using chemical or nuclear-electric-propulsion technologies with minimum-mass vehicle configurations. VISTA also offers onboard artificial gravity and propellant-based shielding from cosmic rays, thus reducing the known hazards and physiological deteriorations to insignificant levels. We emphasize, however, that the degree

    Gas station workers are exposed to chemicals known to be carcinogenic, especially benzene. The objective was to analyze the health problems of female gas station workers by means of sociodemographic and clinical questionnaires, and laboratorial exams. We performed the genotyping of the polymorphisms BRCA1/P871L and BRCA1/Q356R by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism, and of variant allele BRCA2/N372H through direct sequencing. The female workers showed a higher concentration of monocytes (P = 0.039); a greater number of spontaneous abortions (P = 0.025, OR = 4.977, 95% CI = 1.135-30.669); higher tobacco consumption (P = 0.013); and higher alcohol consumption (P = 0.05). The statistical analysis of the polymorphisms associated with the variables monocyte concentration and miscarriage number did not reveal a significant relationship, and smoking and spontaneous abortion were not statistically associated either.

Seu discurso pode ser resumido por uma fórmula: “sou mestiço nas minhas origens, caboclo na minha cultura e cidadão frente aos meus direitos”. A partir de uma sociologia pragmática, que consiste em levar o movimento a sério em sua existência e seu discurso, o texto procura mostrar a configuração ideológica e prática da questão da “igualdade racial”, tal como ela aparece e se manifesta do ponto de vista de seus integrantes. Pretendese assim entender um lugar lógico, entre muitos outros, a partir dos quais se questiona a democracia brasileira. In 2001, the social movement Nação Mestiça arose in the poor suburbs of Manaus. Its proposal can be summarised by a single statement: “I’m mestizo in my origins, caboclo in my culture, and a citizen in relation to my rights.” Adopting a pragmatic sociological approach, which consists in taking the movement seriously in terms of its existence and proposal, the article ‘Nação Mestiça’: Ethnic-Racial Policies Seen from the Manaus Outskirts attempts to demonstrate the ideological and practical confi guration of the “racial equality” issue, as it is appears and is expressed from the viewpoint of the movement’s members. Thus, a logical position is sought, among many others, from where Brazilian democracy is questioned.

    Full Text Available Este trabajo es una réplica parcial y una adaptación del modelo “P-Estrella” diseñado para explicar y predecir la tasa de inflación desde un punto de vista macroeconómico. Según el modelo, el índice general de precios tiene un nivel de equilibrio determinado por las variables sugeridas por la teoría macroeconómica estándar, mientras que el nivel de precios observado puede recibir la influencia de factores aleatorios. Según el modelo, la inflación sigue una trayectoria dominada por la evolución del nivel de precios de equilibrio y por el proceso de corrección de los desequilibrios entre éste y el nivel previamente observado. El método econométrico seguido es el de cointegración y corrección de errores.

  4. The NATO Advanced Study Institute on New Vistas in Electro-Nuclear Physics

    1986-01-01

    The NATO Advanced Study Institute "New Vistas in Electro-Nuclear Physics" was held in Banff, Alberta, Canada from August 22 to September 4, 1985. This volume con­ tains the lecture notes from that Institute. The idea to organize this Institute coincided with the award of funding for a pulse stretcher ring at the University of Saskatchewan's Linear Accelerator Laboratory. This together with the high level of interest in electron accelerators worldwide convinced us that it was an appropriate time to discuss the physics to be learned with such machines. In particular that physics which requires high energy and/or high duty cycle accelerators for its extraction was intended to be the focus of the Institute. Thus the scope of the lec­ tures was wide, with topics ranging from the structure of the trinucleons to quark models of nucleons, QCD, and QHD. The theme however was that we are just trying to under­ stand the nucleus and that the electromagnetic probe can serve as a powerful tool in such a quest.

  5. Characterization of dispersion, attenuation, and anisotropy at the Buena Vista Hills field, California

    We create a log of intrinsic dispersion and attenuation for the Antelope Shale formation of the Buena Vista Hills field, San Joaquin Valley, California. High dispersion (or low Q) values correlate with thin sand and carbonate beds within the Antelope Shale. These beds are at least ten times as permeable as the host shale formation, so this effect provides a possible avenue for seismic prediction of permeability. The dispersion log is formed through comparison of crosswell seismic velocities (measured at approximately 1 kHz) and sonic log velocities (measured at approximately 10 kHz). In order to provide a proper basis for comparison, the sonic log must first be adjusted for field anisotropy, scaling effects, and resolution of measurement. We estimate a local shale anisotropy of about 20% based on correlations generated from published measurements of other shale fields. We apply resolution enhancement to capture the thin sand and carbonate beds, and windowed Backus averaging to match the measurement scales. A modeling study verifies the technique, and shows that beds of thickness greater than 30 cm have a measurement signature. The actual resolution is on the order of the crosswell Fresnel length, or about 7 m for the model study.

  6. Environmental impacts associated with Project Rio Blanco

    Alldredge, A.W.; Whicker, F.W.; Hanson, W.C.

    Project Rio Blanco, an experiment involving deep underground detonation of three 30-kton nuclear explosives designed to stimulate natural gas flow in geologic formations of low permeability, was conducted in western Colorado on 17 May 1973. Environmental impacts associated with this experiment were divided into three categories: radiation, ground motion, and conventional physical activities. Radiation and ground motion are unique to this type experiment while conventional activities would be associated with any type of resource development. The objective of observations made at Rio Blanco was to qualitatively and, where possible, quantitatively ascertain environmental impacts associated with the project. Observations indicated that ground motion and conventional activities appeared to cause the greatest impacts. Ground motion impacts were most severe within 2.4 km of the emplacement well (EW) and were predominantly associated with steep ravine and stream banks and rocky cliffs. Following the detonation, flow and turbidity had increased in a small stream adjacent to the EW. Animals receiving deleterious impacts were those associated with stream banks, cliffs and burrows. No mortality or injury was observed in any large animals. (U.S.)

    This paper presents the conception and the benefits of the integrated supervisory control architecture for performance, aero thermodynamic and mechanical monitoring of the Ubarana Phase V Turbo compressor Station in Guamare-Rn. The compression station has four gas turbines, each one developing 6.640 kW ( 9.600 rpm - ISO power), driving four centrifugal compressors, each one with unitary capacity of 850.000 m 3 /d, arranged in parallel. The integrated architecture allows the continuous tele monitoring of a large range of mechanical and process parameters. Other resources are real time identification of deterioration signs or performance decaying of each machine in service, serving as a precious tool for the operation and maintenance decisions like wash application intervals and partial or general equipment revision. Just for the sake of operational cost impacts: a small increase of 1% in overall thermal efficiency represents a reduction of US$ 60,000 in annual operational cost, since the annual fuel consume nears US$ 6 million (considering 20 MW with 8,000 h).

    This study assessed progress toward achieving sustainable groundwater use in the Sierra Vista Subwatershed of the Upper San Pedro Basin, Arizona, through evaluation of 14 indicators of sustainable use. Sustainable use of groundwater in the Sierra Vista Subwatershed requires, at a minimum, a stable rate of groundwater discharge to, and thus base flow in, the San Pedro River. Many of the 14 indicators are therefore related to long-term or short-term effects on base flow and provide us with a means to evaluate groundwater discharge to and base flow in the San Pedro River. The indicators were based primarily on 10 to 20 years of data monitoring in the subwatershed, ending in 2012, and included subwatershedwide indicators, riparian-system indicators, San Pedro River indicators, and springs indicators.

Siendo anteriormente personajes de escritores cultos de clase media, en un determinado momento histórico todos ellos se convierten en autores de sus propias historias. Nuestra hipótesis es que este cambio se dió con Carolina Maria de Jesus, autora del éxito de ventas Quarto de despejo. Sin embargo, al no haber obtenido el mismo éxito con sus otros libros, la autora terminó siendo tratada como un fenómeno aislado. Franco Moretti, crítico mordaz del viejo vicio de preocuparse por singularidades, abre un camino alternativo de análisis con su obra A literatura vista de longe. A partir de Carolina surgió un gran número de autores que necesitan ser estudiados, cuantificados, tabulados con gráficos, mapas y árboles evolutivos, es decir, necesitan ser analizados con las herramientas del crítico italiano. Tomando como punto de partida las ideas de Moretti, el artículo visualiza el desarrollo de este proceso a partir de la aparición de Carolina. La dificultad yace en obtener datos cuantitativos, principal materia prima de Moretti, lo que nos exige una profunda investigación que tiene que empezar tan pronto como sea posible.

  14. Perspectives of energy technologies: scenarios and strategies at the 2050 vista

    International Nuclear Information System (INIS)

    2008-01-01

    Every two years, the International Energy Agency (IEA) publishes the 'Energy Technology Perspectives' (ETP) report which analyses the foreseeable energy scenarios and strategies at the 2050 vista and stresses on the best available technologies. For the first time, the IEA describes in this study a scenario allowing to divide by two the CO 2 emissions at the world scale, i.e. compatible with the 'factor 4' scenario of industrialized countries. The study estimates the R and D needs and the necessary additional investments to meet the different tendentious and voluntaristic scenarios proposed by the IEA. This 15. session of the cycle of energy-climate conferences aimed at presenting, from the ETP 2008 study, a thorough examination of the present day situation and perspectives of existing or future 'clean' energy technologies through the analysis of several scenarios. An examination of the interpretation of these scenarios at the France and European levels is made in order to define what should be the trends of public policies and international cooperation. This document gathers the transparencies of the two presentations given during this conference. The first presentation by Pieter Boot, Director of the Office of Sustainable Energy Policy and Technology of IEA, makes a synthesis of the ETP study and presents the recommendations of the agency. The second presentation by Olivier Appert, President of the French institute of petroleum (IFP), gives a counterpoint of the first presentation by considering the financing and acceptance aspects, in particular from the French point of view. Finally a debate with the audience completes the presentations. (J.S.)

    We present a study on physical properties for a large distant red galaxy (DRG) sample, using the K-selected multi-band photometry catalog of the COSMOS/UltraVISTA field and the CANDELS near-infrared data. Our sample includes 4485 DRGs with (J - K)AB > 1.16 and KAB DRG morphology are consistent with our rest-frame UVJ color classification; quiescent DRGs are generally compact while star-forming DRGs tend to have extended structures. We find the star formation rate (SFR) and the stellar mass of star-forming DRGs present tight "main sequence" relations in all redshift bins. Moreover, the specific SFR (sSFR) of DRGs increases with redshift in all stellar mass bins and DRGs with higher stellar masses generally have lower sSFRs, which indicates that galaxies were much more active on average in the past, and star formation contributes more to the mass growth of low-mass galaxies than to high-mass galaxies. The infrared-derived SFR dominates the total SFR of DRGs which occupy the high-mass range, implying that the J - K color criterion effectively selects massive and dusty galaxies. DRGs with higher M* generally have redder (U - V)rest colors, and the (U - V)rest colors of DRGs become bluer at higher redshifts, suggesting high-mass galaxies have higher internal dust extinctions or older stellar ages and they evolve with time. Finally, we find that DRGs have different overlap among extremely red objects, BzK galaxies, IRAC-selected extremely red objects, and high-z ultraluminous infrared galaxies, indicating that DRGs are not a special population and they can also be selected by other color criteria.

    Full Text Available Aunque la linterna mágica desarrolló una próspera industria de equipos y satisfizo una variada demanda de prácticas de consumo, a partir del desarrollo de sistemas expresivos llenos de sentido, su estudio ha estado fuera de la planificación académica de la historia de los medios de comunicación. La dispersión de los fondos patrimoniales de la linterna mágica y su indefinición conceptual como objeto de estudio –tanto por la amplitud cronológica de su historia, que discurre entre los siglos XVII y XIX, como por la controvertida interpretación que la adscribe al término 'precine'- son razones que explican como la linterna mágica es todavía un medio de comunicación social en la sombra y que están en el origen del presente acercamiento que tiene como objeto un viaje elíptico y sistemático –articulado en torno a cuatro actos, doce escenas y ochenta vistas- por el universo de las proyecciones audiovisuales anteriores al cine. Abstract in English: Although the magic lantern developed a prosperous equipment industry and satisfied a varied consumer demand based on the development of very sensible expressive systems, its study has been left out of the academic curriculum in the history of mass media. The fact that the sources and documentation concerning magic lanterns are widely scattered has been an obstacle for their systematic study. Both their long history –over three centuries- and the controversy in historical interpretation caused by locating them under the term ‘precinema' have meant that they lack a conceptual definition. This in turn has been a hindrance for considering magic lanterns as an important research subject.

    Full Text Available The urban nucleus of the Porcelain Factory of Vista Alegre reveals a special interest in terms of the evolution of the traditional adobe construction in the town of Ílhavo, located in the district of Aveiro. Presenting a structured philosophy of intervention in the territory since its very beginning, it possesses a rich heritage in the field of construction and architecture. The measures planned and implemented in the second phase of Vista Alegre growth reporting its beginning to the ends of the 30's, and along the 40's, confirm it both in the rehabilitation, extension and new constructions in adobe masonry. Those measures were implemented during the structural changes of the Industrial Unit administration that only until this period belonged to the family of its founder. These changes creates one of the focus of innovation in the region, with new construction strategies and solutions in adobe buildings, which will prolonged the period of use of this construction system, noticeable in buildings dated of 1958 in the Vista Alegre and at least in 1970 in the town.

Examining the inlinks via webometrics studies has attracted particular interests among information researchers. In this study, the number of inlinks to 69 ISI medical journals retrieved by Yahoo, AltaVista, and All The web Search Engines were examined via a comparative and Webometrics study. For data analysis, SPSS software was employed. Findings revealed that British Medical Journal website attracted the most links of all in the three search engines. There is a significant correlation between the number of External links and the ISI impact factor. The most significant correlation in the three search engines exists between external links of Yahoo and AltaVista (100% and the least correlation is found between external links of All The web & the number of pages of AltaVista (0.51. There is no significant difference between the internal links & the number of pages found by the three search engines. But in case of impact factors, significant differences are found between these three search engines. So, the study shows that journals with higher impact factor attract more links to their websites. It also indicates that the three search engines are significantly different in terms of total links, outlinks and web impact factors

    2001-01-01

    Settlement and deforestation surrounding the Brazilian town of Rio Branco are seen here in the striking 'herring bone' deforestation patterns that cut through the rainforest. Rio Brancois the capital of the Brazilian state of Acre and is situated near the border with northeastern Bolivia. The town is a center for the distribution of goods, including rubber, metals, medicinal plants, Brazil nuts and timber. Colonization projects in the region are supported by farming, logging activities, and extensive cattle ranching. Much of the surrounding terrain is of a poorly-draining clay hardpan soil, and heavy rainfall periodically converts parts of the forested region to swamp.The large overview image was acquired by the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera on July 28, 2000, and covers an area of 336 kilometers x 333 kilometers. A plume of smoke is visible north of the Rio Branco road, which roughly parallels the slender, twisting Rio Abuna. Most of the major rivers in the image provide reference points for state or international (Bolivia-Brazil) boundaries, and flow northeast to the Rio Madeira (east of the smoke plume). The border between Acre and the Bolivian department of Pando is marked by the Rio Abuna. Pando's southern boundary with the department of Beni is marked by the Rio Madre de Dios, the large river in the lower half of the image.The two higher-resolution inset images highlight a settled area north of the town of Rio Branco. These nadir views cover an area of 60 kilometers x 67 kilometers, and were acquired eleven months apart during Terra orbits 3251 and 8144. In the later image, more haze is present, possibly due to smoke from fires on that day. Comparing the two images provides a method of measuring the changes and expansion in the area of cleared land. One newly cleared patch is apparent near the middle of the later image, slightly off to the right. This polygon represents an area of about 16 square kilometers, or 4000

    GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network. In this communication we focus on the determination of the

    At the northeast tip of the Yucatan Peninsula - where the Caribbean meets the Gulf - lies the ancient Maya port site of Vista Alegre. The inhabitants of this site, much like the people living nearby today, were forced to contend with the challenging coastal environment of Laguna Holbox. The sediment-rich, low gradient of the north coast presents a contrasting landscape compared to the Caribbean coast, where water resources are of much larger magnitude and evident in the extensive systems of cenotes (sinkholes) and underground rivers that supported pre-Columbian sites along this eastern rocky sediment-poor coastline. For past inhabitants the north coast was a mosaic of low-lying, non-arable zones where access to potable water was a challenge for inhabitants well into the 20th century. By bringing together scholars from the fields of archaeology, coastal ecology, geoarchaeology, and hydrogeology, the Proyecto Costa Escondida is focusing on the dynamic relationship between the Maya and their coastal landscape over the past 3000 years. To date we have collected 12 manual push-cores from the shallow waters surrounding Vista Alegre, which have been analyzed at 1 cm resolution using standard methods for Loss on Ignition (LOI), δ18Ocarb and δ13Ccarb of bulk carbonate, granulometry, micropalentology, and AMS radiocarbon dating. In addition to have baseline comparative data, we have conducted near-shore and terrestrial coastal ecological surveys along with the mapping of coastal water salinity and temperatures in the dry and wet seasons. Overall, the chemical proxies, lithology, and paleosalinity model reconstructed to date reveal four onlapping parasequences representing an overall transgression of the coastline with strong seasonality of water chemistry that has been changing under the control of rising sea levels over the past 3000 years. The sedimentation rate and timing of the transition to marine is in reasonable agreement with local sea level curves meaning that the

    Full Text Available Este artigo discute o assédio moral nas instituições bancárias, tomando por base uma discussão conceitual do tema e um estudo empírico desenvolvido com funcionários de um banco da região Norte do Brasil. Tendo em vista uma delimitação teórico-conceitual, apresenta, com base em estudiosos consagrados na literatura, breve histórico da discussão sobre o fenômeno, bem como definições e características que o distinguem de outros conflitos recorrentes em ambientes de trabalho. Discute também o papel das organizações de trabalho quanto ao assédio. Apresenta ainda resultados de pesquisa realizada em agências bancárias durante os meses de julho, agosto e setembro de 2010 por meio de entrevistas individuais semiestruturadas, aplicadas a 37 voluntários que exerciam diferentes cargos nessas agências. Foi possível identificar que o assédio moral, como forma de violência, é um fenômeno reconhecido pelos bancários em seu ambiente de trabalho e que, em geral, os sujeitos associam o assédio moral à forma de gestão por pressão, focada em metas, produção e competitividade. Os resultados também incitam a reflexão de que é necessário tratar o assédio moral em uma perspectiva coletiva, como uma questão social, e não individual.

    The SMART uses a two-phase natural circulation in the PRHRS loop to remove the heat from the steam generators to the PRHRS heat exchangers, while a single phase natural circulation occurs in the primary loop to transfer the decay heat from the core to the steam generator. Natural circulation operation with a power range of 20 ∼ 25% was considered for SMART and nowadays the possibility of increasing the power level during the natural circulation operation is being investigated. Previously Park et al. performed several experiments by using the VISTA facility on the thermal-hydraulic characteristics of the PRHRS for the SMART-P, which includes a single-phase natural circulation in the primary loop. From the analysis with the TASS-SMR code it was shown that the reference temperature for the primary steam generator inlet temperature should be increased in order to compensate for the decreased core flow. To investigate the possibility of an increase of the power and reference temperature, it is necessary to get experimental data to characterize the natural circulation phenomena in the primary loop of the SMART. In this paper, the characteristics of natural circulation in the primary loop are experimentally investigated during various operational conditions by using the VISTA facility

    In reviewing the work packages included in the Rio Earth's Summit Agenda 21, intended as an activities guideline for international cooperation to ensure environmental protection with sustainable growth for all nations, this paper points out the areas which present the greatest obstacles in the establishment of common accords and discusses the directions being taken to surmount these obstacles. A major obstacle concerns uncertaindes in specifying limits on carbon dioxide emissions and their effects on world climate. Another concerns suitable methods to help finance effective technology transfer to developing countries. With regard to the former problem, a 'no regret' approach has been proposed to limit current C02 reduction interventions to those levels which, in all certainty, would not incur any future regrets once scientific knowledge has advanced enough to allow more accurate assessments of greenhouse gas/climate change inter-relationships. With regard to the latter problem, attempts are being made to reduce possible negative impacts on the petroleum industry due to energy surcharges suggested as a source of funding for technology transfer/environmental protection programs.

    A 'business-as-usual' energy scenario is the most probable scenario where the energy demand follows the trends of the past and where no new energy policy is implemented. This work is a complement to the three contrasted energy scenarios built in 1998 by the 'Energy 2010-2020' prospective group of the French general commission of national development. The scenario built in this study is only a reference which allows the measure the efforts made to reach political goals. The main conclusion of this scenario is the increase of the CO 2 emissions under the double effect of the economic growth and of the cessation of the nuclear program which becomes non-competitive with respect to the gas prices and actualization rates retained in the scenario. The main constraint of the energy future is incontestably the necessary fight against the greenhouse effect. (J.S.)

    We performed a deep wide-field (6.76 sq. deg) near-infrared survey with the VISTA telescope that covers the entire extent of the Carina nebula complex (CNC). The point-source catalog created from these data contains around four million individual objects down to masses of 0.1 M⊙. We present a statistical study of the large-scale spatial distribution and an investigation of the clustering properties of infrared-excesses objects, which are used to trace disk-bearing young stellar objects (YSOs). A selection based on a near-infrared (J-H) versus (H-Ks) color-color diagram shows an almost uniform distribution over the entire observed area. We interpret this as a result of the very high degree of background contamination that arises from the Carina Nebula's location close to the Galactic plane. Complementing the VISTA near-infrared catalog with Spitzer IRAC mid-infrared photometry improves the situation of the background contamination considerably. We find that a (J-H) versus (Ks- [4.5]) color-color diagram is well suited to tracing the population of YSO-candidates (cYSOs) by their infrared excess. We identify 8781 sources with strong infrared excess, which we consider as cYSOs. This sample is used to investigate the spatial distribution of the cYSOs with a nearest-neighbor analysis. The surface density distribution of cYSOs agrees well with the shape of the clouds as seen in our Herschel far-infrared survey. The strong decline in the surface density of excess sources outside the area of the clouds supports the hypothesis that our excess-selected sample consists predominantly of cYSOs with a low level of background contamination. This analysis allows us to identify 14 groups of cYSOs outside the central area.Our results suggest that the total population of cYSOs in the CNC comprises about 164 000 objects, with a substantial fraction (~35%) located in the northern, still not well studied parts. Our cluster analysis suggests that roughly half of the cYSOs constitute a

    Objective: To assess the diagnostic value of fat-suppressed (FS) three-dimensional (3D) volume isotropic turbo spin echo acquisition (VISTA) imaging in detecting radial and root tears of the meniscus, including the reader-defined reformatted axial (RDA) plane. Materials and methods: Twenty-three patients with arthroscopically confirmed radial or root tears of the meniscus underwent magnetic resonance imaging (MRI) with 2D and FS 3D VISTA sequences. MRIs were reviewed independently by two musculoskeletal radiologists blinded to the arthroscopic findings. Sensitivity, specificity, accuracy, and interobserver agreement were calculated for radial and root tears. Both radiologists reported confidence scale for the presence of meniscal tears in 2D axial imaging, 3D axial imaging, and RDA imaging, based on a five-point scale. Wilcoxon's signed rank test was used to compare confidence scale. Results: The sensitivity, specificity, and accuracy of FS 3D VISTA MR imaging versus 2D MR imaging were as follows: 96%, 96%, and 96% versus 91%, 91%, and 91%, respectively in reader 1, and 96%, 96%, and 96% versus 83%, 91%, and 87%, respectively, in reader 2. Interobserver agreement for detecting meniscal tears was excellent (κ = 1) with FS 3D VISTA. The confidence scale was significantly higher for 3D axial images than 2D imaging (p = 0.03) and significantly higher in RDA images than 3D axial image in detecting radial and root tears. Conclusions: FS 3D VISTA had a better diagnostic performance in evaluating radial and root tears of the meniscus. The reader-defined reformatted axial plane obtained from FS 3D VISTA MR imaging is useful in detecting radial and root tears of the meniscus.

    2008-02-01

    Full Text Available I take the image of the crossroads first as a way of elucidating the approach Wim Wenders takes to making films and Ry Cooder to making music, and to the implicit politics that can be derived from their practice. I then look at Paris, Texas as a crossroads film to examine how the thematic and formal properties of the film can throw light on the nature of Cooder’s and Wenders’s collaboration on it. This is then used as a base from which to launch an attempt to demolish once and for all the widely held view that Buena Vista Social Club was an example of cultural imperialism.

    Full Text Available Purpose. To report the impact of baseline central retinal thickness (CRT on outcomes in patients with diabetic macular edema (DME in VIVID-DME and VISTA-DME. Methods. Post hoc analyses of two randomized controlled trials in which 862 DME patients were randomized 1 : 1 : 1 to treatment with intravitreal aflibercept 2.0 mg every 4 weeks (2q4, intravitreal aflibercept 2.0 mg every 8 weeks after five initial monthly doses (2q8, or macular laser photocoagulation at baseline and as needed. We compared visual and anatomical outcomes in subgroups of patients with baseline CRT < 400 μm and ≥400 μm. Results. At weeks 52 and 100, outcomes with intravitreal aflibercept 2q4 and 2q8 were superior to those in laser control-treated patients regardless of baseline CRT. When looked at in a binary fashion, the treatment effect of intravitreal aflibercept versus laser was not significantly better in the ≥400 μm than the <400 μm group; when looked at as a continuous variable, baseline CRT seemed to have an impact on the treatment effect of intravitreal aflibercept versus laser. Conclusions. Post hoc analyses of VIVID-DME and VISTA-DME demonstrated the benefits of intravitreal aflibercept treatment in DME patients with baseline CRT < 400 μm and ≥400 μm. This trial is registered with NCT01331681 and NCT01363440.

    Full Text Available RESUMO O prontuário do paciente constitui uma ferramenta fundamental para a prestação do cuidado em saúde, podendo ser definido como um registro padronizado e organizado de toda a informação referente à saúde de um indivíduo, desde o nascimento até a morte. Na década de 1970, impulsionados pelo crescente desenvolvimento da tecnologia, surgem os primeiros sistemas de Prontuários Eletrônicos do Paciente (PEP, sob uma proposta de informatização dos registros em saúde. Por meio de uma criteriosa pesquisa bibliográfica, questões concernentes ao prontuário eletrônico do paciente foram discutidas, especialmente do ponto de vista ético. Os avanços tecnológicos aplicados à área de saúde devem ser implantados de maneira crítica, em que pesem as consequências imprevistas que possam ter quanto à relação médico-paciente, uma vez que o cuidado e o respeito devem ser prioridade, e não os interesses particulares. Por isso, uma análise apenas técnica não abarca elementos que podem ser compreendidos à luz dos conceitos éticos, os quais norteiam escolhas baseadas no interesse comum.

    Perhaps the most published graphic in the oil industry is one that traces the price of oil through time. It is used as an overlay to correlate everything from the history of rig activity levels to predicting coming oil shortages and gluts. In Rio de Janeiro this month during the 17th World Petroleum Congress, Dr Don Paul of ChevronTexaco and Saudi Aramco's Abdulaziz Al-Kaabi used it to illustrate the role research and technology development must play within the oil industry. The author discusses the way the oil industry is spending money on research and development, he explains that in the past 20 years the biggest innovation in the industry has been 3D seismic. The critical strategy for oil business was the adaptation of 3D seismic from another industry which was then moulded for its own needs.

Os parâmetros (temperatura, turbidez, pH, condutividade elétrica, oxigênio dissolvido (OD, amônia, nitrito e fosfato foram avaliados seguindo a metodologia do APHA (1998. Os resultados ratificam a existência de atividades causadoras da elevada concentração do teor de amônia e do baixo nível de OD no ambiente aquático. A dinâmica da maré e as condições físicas do ambiente aceleraram a reação de nitrificação. As concentrações de fosfato e nitrito estiveram dentro do limite máximo estabelecido na resolução n° 357/05 do CONAMA. Tendo em vista a potencialização dos riscos de contaminação dos mariscos devido à poluição hídrica, faz-se necessária uma intervenção dos órgãos fiscalizadores quanto ao lançamento direto de resíduos sólidos e líquidos no estuário, de forma a garantir a integridade do ambiente aquático e a saúde dos consumidores.

    Stanislaus-San Joaquin county line, which also defines the northern boundary of the San Joaquin Basin Province. In the vertical dimension, the AU extends from the uppermost crystalline basement to the topographic surface (fig. 21.3), to allow for the possibility of down-section charge across fault surfaces and up-dip migration. The gas in this AU may be sourced from the Winters- Domengine(?) petroleum system, located in the Sacramento Valley north of the San Joaquin Valley, as defined by Magoon and others (1994a,b) (question mark notation derives from convention of Magoon and Dow, 1994, and indicates speculative genetic relationship between hydrocarbons and source rock). The Winters-Domengine Total Petroleum System defined for this assessment contains about 7.2 trillion cubic feet (TCF) of known, recoverable gas and includes the Rio Vista gas field, which alone accounts for 4 TCF of recoverable gas through 2002 (CDOGGR, 2003). Alternatively, the northern nonassociated gas may be sourced from the Moreno Formation within the San Joaquin Valley itself.

    Full Text Available O objetivo deste artigo, resultado de pesquisa que deu origem à Monografia de Conclusão de Curso em Hotelaria, da UAM, 2011, é apresentar os resultados de uma investigação sobre o grau de satisfação dos visitantes do Santuário mariano de Aparecida do Norte, S.P, relativo ao sistema de hospedagem e serviços gastronômicos, supostamente insuficientes e deficitários na cidade. O trabalho fundamenta-se teoricamente nas idéias do geógrafo Christian Dennys Monteiro Oliveira que compreende o turismo religioso como peregrinação contemporânea e o visitante de Aparecida como romeiro urbano acostumado a acessar bens e serviços das metrópoles. Metodologicamente primeiramente foi realizada uma pesquisa exploratória com consultas a sites oficiais e comerciais que levaram à confirmação da precariedade dos serviços de hotelaria e alimentação na cidade. Em um segundo momento foi aplicado um questionário em uma amostra composta de 100 visitantes, entre hóspedes e não-hóspedes da cidade, que recebeu posteriormente análise probabilística. Os resultados apontam uma avaliação majoritariamente positiva em relação aos recursos de hospedagem e alimentação de Aparecida. Concluiu-se que a cidade e a municipalidade sofreram um atrofiamento em função da presença do Santuário, que exerce um monopólio das ações receptivas impostas pelo poder clerical desde suas origens, não havendo políticas públicas para o planejamento e gestão do turismo religioso em Aparecida. Por outro lado, concluiu-se que o novo romeiro urbano que para lá se dirige habituado ao uso de bens turísticos, apresenta uma crítica diminuída em relação à qualidade dos serviços ofertados na região, conformando-se com a precariedade. É possível que a submissão às deficientes condições de hospedagem e serviços alimentícios seja o remanescente contemporâneo do sofrimento que no passado se fazia necessário na peregrinação, penitência ou romaria.

    2017-08-01

    Recent policies adopted in Cuba are producing a significant turn into the country's socioeconomic dynamics. Past shifting circumstances have demonstrated the positive and negative implications on heritage sites. In this regard, this paper presents a first stage of a research project aimed at monitoring the impact of socioeconomic dynamics on local heritage sites. The research partial results focus on the documentation of the evolution of a case study: Vista Alegre District in the city of Santiago de Cuba. Scholars have noted that the District's urban design and historic building stock represent its most significant heritage values. Such qualities are under permanent threat due to transformations and deterioration. In order to analyse current site condition, and to understand transformations as a result of socioeconomic dynamics, a Geographic Information System (GIS) was implemented as a monitoring and documenting tool. The GIS allowed integrating data related to the evolution of the urban layout, and the heritage buildings. Data was sourced from heritage management and urban planning offices, as well as from previous studies on the site. In addition, the analysis of remote sensing imagery, and a field survey helped to update the existing records, and to include new information with the purpose of assessing the integrity of heritage values. At this stage, maps that describe the site evolution, the significant changes over time, and the alterations to character defining elements served to identify sectors of different scenic qualities. Results are essential to contribute to draft management strategies as part of decision making.

    We search for extragalactic sources in the VISTA Variables in the Vía Láctea survey that are hidden by the Galaxy. Herein, we describe our photometric procedure to find and characterize extragalactic objects using a combination of SExtractor and PSFEx. It was applied in two tiles of the survey: d010 and d115, without previous extragalactic IR detections, in order to obtain photometric parameters of the detected sources. The adopted criteria to define extragalactic candidates include CLASSSTAR 0.002 and the colors: 0.5 0.44 mag. We detected 345 and 185 extragalactic candidates in the d010 and d115 tiles, respectively. All of them were visually inspected and confirmed to be galaxies. In general, they are small and more circular objects, due to the near-IR sensitivity to select more compact objects with higher surface brightness. The procedure will be used to identify extragalactic objects in other tiles of the VVV disk, which will allow us to study the distribution of galaxies and filaments hidden by the Milky Way.

    The guava fruit (Psidium guajava) is among the most strongly affected by fruit flies in Brazil. In the Brazilian Amazon, 11 species of Anastrepha have been reported in guava orchards to date. This work aimed to identify the species of Anastrepha present in a guava orchard in the municipality of Boa Vista, determine the species infesting the fruits, and identify any parasitoids present. Two McPhail traps with food bait were installed and weekly collections were made between January and December 2008. Fruits were also collected systematically during this period, with a view to determining the association between host plant and tephritid species. Nine species of Anastrepha were identified, in addition to one specimen belonging to a probable new species. Anastrepha striata Schiner, Anastrepha sororcula Zucchi, Anastrepha obliqua (Macquart), and Anastrepha fraterculus (Wiedemann) were the dominant species in the orchard, accounting for 84.8% of all captured individuals. All females collected directly from fruits were A. striata. Doryctobracon areolatus (Szépligeti) was the only parasitoid species obtained. In this work, Anastrepha ethalea (Walker) is reported for the first time in the state of Roraima.

    We present a new analysis of the stellar mass function and morphology of recently quenched galaxies (RQGs), whose star formation has been recently quenched for some reason. The COSMOS2015 catalog was exploited to select those galaxies at 0.2 < z < 4.8, over 1.5 deg{sup 2} of the Cosmic Evolution Survey (COSMOS) UltraVISTA field. This is the first time that RQGs are consistently selected and studied in such a wide range of redshift. We find increasing number density of RQGs with time in a broad mass range at z > 1, while low-mass RQGs start to grow very rapidly at z < 1. We also demonstrate that the migration of RQGs may largely drive the evolution of the stellar mass function of passive galaxies. Moreover, we find that the morphological type distribution of RQGs are intermediate between those of star-forming and passive galaxies. These results indicate that RQGs represent a major transitional phase of galaxy evolution, in which star-forming galaxies turn into passive galaxies, accompanied by the build up of spheroidal component.

    U, th and K concentrations were determinated on 239 samples collected from a grid of 3 km 3 in a part of the Bela Vista Farm, Jaguarari County, Bahia. The samples are mainly surface soils and rocks, but includes a few ones from trenches as well. This area consist of metamorphic rocks of granulitic facies, pait of the precambrian migmatitic complex of Bahia, with banded gneisses, pyroxenites and amphibolites. Since the area studied is closer to a cupriferous district, in addition to the radioactive elements determined by gamma-ray spectrometry, the samples were also analysed for copper and nickel content by flame atomic absorption in order to abtain complementary geochemical information. Correlation between elements as well as with local geology studied and its was found that: a) except for uranium, the isoconcentration for all elements were aproximately parallel to the geological structure and geophysical anomaly. b) potassium showed an irregular distribution. c) uranium concentration were in general very low. d) The U/Th ratios were very high. Indicating a probable low geochemical evolution. e) The concentration found for C, Ni and Th were closer to average concentrations of intermediate igneous rocks than those of basic and ultra basic rocks.

A Case Study into the updated Drugs Act in the City of Rio de Janeiro, at a wider scope, talks about the con­sumption of drugs in Brazil, and in particular in the city of Rio de Janeiro. How is drug use treated? What hap­pens to the users? These questions, however, may be approached from various angles. This study is based on the standpoint of drugs consumers themselves and also on the legal arguments and representations – as they inform powerful regulatory systems over drugs. The functioning of the Criminal Justice System is discussed based on the developments of a case of recorded “drug trafficking” which later becomes “drug use”.Keywords: Rio de Janeiro, Brazilian Criminal Justice System, drug consumption, users, dealers

    1976-01-01

    Project Rio Blanco, an experiment involving deep underground detonation of three 30-kiloton nuclear explosives designed to stimulate natural gas flow in geologic formations of low permeability, was conducted in western Colorado on 17 May 1973. Environmental impacts associated with this experiment were divided into three categories: radiation, ground motion, and conventional physical activities. The objective of observations made at Rio Blanco was to qualitatively and, where possible, quantitatively ascertain environmental impacts associated with the project. Observations indicated that ground motion and conventional activities appeared to cause the greatest impacts. Ground motion impacts were most severe within 2.4 km of the emplacement well (EW) and were predominantly associated with steep ravine and stream banks and rocky cliffs. Following the detonation, flow and turbidity had increased in a small stream adjacent to the EW. Animals receiving deleterious impacts were those associated with stream banks, cliffs and burrows. No mortality or injury was observed in any large animals. Based on overall results it appears important to give adequate attention to environmental effects resulting from nuclear fracturing experiments

The analysis of the work allows us to penetrate in some problems that have an effect on the knowledge of his production. In particular it is very important the long campaign of work developed by the painter through the lands of the Kingdom of Aragón in 1563. The view of Belmonte will be just the final point of his trip, that can be only understood in relation with the journey Philip II made through the same lands some months later. The present article ends in a detailed exam of the drawing, contrasting it with the own historical reality of Belmonte as for its general composition and details.

Já os alvos específicos são: identificar as formas de tributação existentes que podem ser utilizadas pelas MPE e verificar qual é a mais viável. Para atingir os objetivos deste estudo, foi realizada pesquisa bibliográfica a partir de artigos e livros do acervo da Faculdade Anhanguera, da Universidade Católica Dom Bosco (UCDB e de acervos pessoais, bem como de artigos de periódicos e legislação disponíveis na internet e manuais de pesquisa no site do Serviço Brasileiro de Apoio às Micro e Pequenas Empresas (Sebrae. Dos resultados encontrados, verificou-se que as MPE possuem papel relevante para a economia e, por esse motivo, o governo, nas últimas décadas, tem proporcionado vários incentivos visando estimular a abertura de mais empresas desse porte, bem como evitar que muitas entrem em falência, tendo em vista que pesquisas realizadas, principalmente pelo Sebrae, demonstram que é alto o índice de MPE que entram em falência todos os anos. Nas últimas décadas, após os incentivos adotados, entre eles a criação do Simples, nova forma de tributação especial para as MPE, verificou-se uma redução no fechamento de empresas desse porte, porém, o índice continua elevado. Várias são as causas para a falência das MPE, e dentre elas se destaca a alta carga tributária. Dessa forma, torna-se imprescindível que os empresários invistam na realização do planejamento tributário, a fim de escolher a melhor forma de tributação para evitar a falência.

    For the Luminescent Oxygen Channeling Immunoassay (LOCI) technology as established for Dimension Vista 1500, assays have been developed for the serum tumor markers AFP, CEA, PSA and free PSA. We performed a method analysis for these parameters using the Immulite 2000 XPI. Determination of within-day and total imprecision of the methods was carried out according to CLSI guidelines with three serum pools. In addition, parallel measurements were performed with both systems in 1,871 routine serum samples and correlations were calculated. Calculated total imprecision of the three serum pools for AFP was 3.8 - 4.3%, for CEA 3.3 - 4.3%, for tPSA 3.6 - 4.0% and for fPSA it was 3.5 - 8.2%. Correlations of these markers across the entire value range were very good with the following correlation coefficients: 0.997 for AFP, 0.996 for CEA, 0.971 for tPSA and 0.988 for fPSA. While values for AFP and tPSA from both methods were comparable (slopes 1.02 and 1.01), lower values were measured for CEA and fPSA with the Dimension Vista (slopes 0.83 and 0.91). For AFP, a sample cluster with considerably higher values than with Dimension Vista was observed in the lower measurement range (CEA, tPSA and fPSA, as developed with the LOCI technology for the Dimension Vista, show good comparability with results obtained from the Immulite 2000 XPI. However, lower measurement ranges for CEA and fPSA as well as individual divergences, especially with AFP, must be taken into consideration in the event of method changeover.

    Full Text Available O objetivo deste artigo é verificar a relação entre o mercado futuro e o mercado à vista no Brasil, de forma a observar o comportamento da volatilidade nesses mercados e inferir relações de causalidade. A análise utiliza o mercado de ações, em um período bastante instável, incluindo a ocorrência de choques externos e um grande aumento na entrada de capital para investimento em bolsa. A hipótese de causalidade entre os mercados futuro e à vista é testada utilizando-se os correlogramas cruzados das volatilidades e um modelo GARCH bivariado. Os resultados nos permitem afirmar que o mercado à vista lidera a transmissão de informações no mercado, o que implica que o mercado futuro não causa aumento de volatilidade no mercado à vista.The objective of this paper is to evaluate the evidence of causality between the future and spot markets of stocks in Brazil, verifying if the former has unstabilized the latter, thus increasing its volatility. We analyse a period that includes external shocks and changes in the exchange rate policy. Causality from future to spot markets is tested using both the volatilities cross-correlogram and a bivariate GARCH model. The results allow us to state that the spot market leads the information transmission of the market. Thus the future market does not cause increase of volatility in the spot market.

    The SMART design is characterized by the introduction of simplified and improved safety systems such as PRHRS, and its integral arrangement of the reactor vessel assembly. The integrated reactor vessel assembly consists of a reactor core, eight steam generators, four reactor coolant pumps, and a steam pressurizer, and it has four trains of a secondary system and passive residual heat removal system. The SMART design was fully assessed through various thermal-hydraulic validation tests during the licensing review process. Among them, a small-scale integral effect test facility of VISTA-ITL was used to investigate various thermal-hydraulic phenomena during design basis accident scenarios such as SBLOCA and CLOF, and the acquired data were used to validate the related thermal-hydraulic models of the safety analysis codes such as MARS-KS and TASS/SMR-S. The VISTA-ITL facility is a reduced height, 1/1310-volume scaled test facility with a single train of a secondary system and PRHRS. Recently, a large-scale integral effect test facility of FESTA was constructed in KAERI and a set of integral effect tests for design basis accident scenarios is also being performed. The role of FESTA could be extended to examine and verify the normal, abnormal, and emergency operating procedures required during the construction phases of SMART. It could be called as a counterpart test when similar experiments are performed in differently scaled facilities. It is clear that transient scenarios measured in the experimental rigs cannot be directly extrapolated to the plant conditions. Nevertheless one of the objectives of counter-part tests is to evaluate the influence of the geometric dimensions of the loops upon the evolution of a given accident. In this paper the counterpart test results with both the VISTA-ITL and FESTA facilities will be compared on a SBLOCA scenario of the SIS line break for the SMART design. As counter-part tests for an SBLOCA for the SMART design, two integral effect

    We present the combination of optical data from the Science Verification phase of the Dark Energy Survey (DES) with near-infrared (NIR) data from the European Southern Observatory VISTA Hemisphere Survey (VHS). The deep optical detections from DES are used to extract fluxes and associated errors from the shallower VHS data. Joint seven-band (grizYJK) photometric catalogues are produced in a single 3 sq-deg dedicated camera field centred at 02h26m-04d36m where the availability of ancillary multiwavelength photometry and spectroscopy allows us to test the data quality. Dual photometry increases the number of DES galaxies with measured VHS fluxes by a factor of ~4.5 relative to a simple catalogue level matching and results in a ~1.5 mag increase in the 80 per cent completeness limit of the NIR data. Almost 70 per cent of DES sources have useful NIR flux measurements in this initial catalogue. Photometric redshifts are estimated for a subset of galaxies with spectroscopic redshifts and initial results, although currently limited by small number statistics, indicate that the VHS data can help reduce the photometric redshift scatter at both z < 0.5 and z > 1. We present example DES+VHS colour selection criteria for high-redshift luminous red galaxies (LRGs) at z ~ 0.7 as well as luminous quasars. Using spectroscopic observations in this field we show that the additional VHS fluxes enable a cleaner selection of both populations with <10 per cent contamination from galactic stars in the case of spectroscopically confirmed quasars and <0.5 per cent contamination from galactic stars in the case of spectroscopically confirmed LRGs. The combined DES+VHS data set, which will eventually cover almost 5000 sq-deg, will therefore enable a range of new science and be ideally suited for target selection for future wide-field spectroscopic surveys.

    Full Text Available La tortícolis muscular congénita es una entidad frecuente, presente al nacimiento como una banda fibrosa o tumor en la región del músculo esternocleidomastoideo, que produce cambios restrictivos reflejados en trastornos progresivos del crecimiento y posición de la cabeza y en la rotación y flexión del cuello. El diagnóstico y tratamiento oportunos con fisioterapia y aparatología pueden evitar su secuencia de asimetría craneofacial y daño ocular, de difícil corrección una vez instaurados. Los casos que no responden al tratamiento médico inicial se benefician de cirugía. Presentamos la experiencia quirúrgica con 16 pacientes entre 9 y 32 años con seguimiento de entre 10 semanas y 15 años. El tratamiento quirúrgico consistió en 3 tenotomías de las inserciones del músculo esternocleidomastoideo a través de abordaje directo por dos incisiones pequeñas. Cuantificamos la mejoría de la posición de la cabeza por mediciones angulares en las fotografías pre y postoperatorias en vistas anterior y posterior, demostrando correcciones de entre el 53 y el 100% con promedio del 83% . En algunos casos medimos la movilidad del cuello con un transportador de ángulos confeccionado en consulta. En todos los casos logramos mejoría sustancial, sin complicaciones y con cicatrices aceptables; la columna lateral del cuello en el sitio del músculo seccionado recuperó su continuidad, sin percepción de corte abrupto, depresión o hundimiento. No observamos correlación entre la mejoría lograda y la severidad de la deformidad, ni tampoco con la edad del paciente en el momento de la cirugía, ya que a pesar de que en algunos casos había finalizado el crecimiento y el estado era avanzado, la mejoría fue buena.

    We report the discovery of a massive ultracompact quiescent galaxy that has been strongly lensed into multiple images by a foreground galaxy at z 0.960. This system was serendipitously discovered as a set of extremely K s -bright high-redshift galaxies with red J – K s colors using new data from the UltraVISTA YJHK s near-infrared survey. The system was also previously identified as an optically faint lens/source system using the COSMOS Advanced Camera for Surveys (ACS) imaging by Faure et al. Photometric redshifts for the three brightest images of the source galaxy determined from 27-band photometry place the source at z = 2.4 ± 0.1. We provide an updated lens model for the system that is a good fit to the positions and morphologies of the galaxies in the ACS image. The lens model implies that the magnification of the three brightest images is a factor of 4-5. We use the lens model, combined with the K s -band image, to constrain the size and Sérsic profile of the galaxy. The best-fit model is an ultracompact galaxy (R e = 0.64 +0.08 –0.18 kpc, lensing-corrected), with a Sérsic profile that is intermediate between a disk and a bulge profile (n 2.2 +2.3 – 0 .9 ), albeit with considerable uncertainties on the Sérsic profile. We present aperture photometry for the source galaxy images that have been corrected for flux contamination from the central lens. The best-fit stellar population model is a massive galaxy (log(M star /M ☉ ) = 10.8 +0.1 –0.1 , lensing-corrected) with an age of 1.0 +1.0 –0.4 Gyr, moderate dust extinction (A v = 0.8 +0.5 –0.6 ), and a low specific star formation rate (log(SSFR) –1 ). This is typical of massive ''red-and-dead'' galaxies at this redshift and confirms that this source is the first bona fide strongly lensed massive ultracompact quiescent galaxy to be discovered. We conclude with a discussion of the prospects of finding a larger sample of these galaxies.

    Measurement of a precessional rate of a gas, such as an alkali gas, in a magnetic field is made by promoting a non-uniform precession of the gas in which substantially no net magnetic field affects the gas during a majority of the precession cycle. This allows sensitive gases that would be subject to spin-exchange collision de-phasing to be effectively used for extremely sensitive measurements in the presence of an environmental magnetic field such as the Earth's magnetic field.

    To compare image quality of three-dimensional volume isotropic T 2 weighted fast spin echo (3D VISTA) and two-dimensional (2D) T 2 weighted images (T2WI) for evaluation of triangular fibrocartilage (TFC) and to investigate whether 3D VISTA can replace 2D T 2 WI in evaluating TFC injury. This retrospective study included 69 patients who received wrist MRIs using both 2D T 2 WI and 3D VISTA techniques for assessment of wrist pathology, including TFC injury. Two radiologists measured the signal-to-noise ratio (SNR) and the contrast-to-noise ratio (CNR) of the two sequences. The anatomical identification score and diagnostic performance were independently assessed by two interpreters. The diagnostic abilities of 3D VISTA and 2D T 2 WI were analysed by sensitivity, specificity and accuracy for diagnosing TFC injury using surgically or clinically confirmed diagnostic reference standards. 17 cases (25%) were classified as having TFC injury. 2 cases (12%) were diagnosed surgically, and 15 cases (88%) were diagnosed by physical examination. 52 cases (75%) were diagnosed as having intact TFC. 8 of these cases (15%) were surgically confirmed, while the others were diagnosed by physical examination and clinical findings. The 3D VISTA images had significantly higher SNR and CNR values for the TFC than 2D T 2 WI images. The scores of 3D VISTA's total length, full width and sharpness were similar to those of 2D T 2 WI. We were unable to find a significant difference between 3D VISTA and 2D T 2 WI in the ability to diagnose TFC injury. 3D VISTA image quality is similar to that of 2D T 2 WI for TFC evaluation and is also excellent for tissue contrast. 3D VISTA can replace 2D images in TFC injury assessment. Advances in knowledge: 3D VISTA image quality is similar to that of 2D T 2 WI for TFC evaluation and is also excellent for tissue contrast. 3D VISTA can replace 2D images in TFC injury assessment.

Portanto o presente trabalho teve por objetivo analisar e discutir o sistema viário das estradas rurais da bacia do Rio das Pedras, Guarapuava-PR e a construção de caixas de contenção como medida preventiva para dissipar energia e conseqüentemente a entrada de sedimentos nos canais fluviais. No estudo utilizou-se de dados cartográficos e de campo para mensurar as estradas rurais e as caixas de contenção. Por meio da análise dos resultados constatou-se que o número de caminhos internos supera as estradas principais, que em grande parte não possui dissipadores de energia, potencializando a entrada de sedimentos nos cursos d‘água. Em dez pontos selecionados aleatoriamente verificou-se 792 cruzamentos de estradas rurais e cursos d’água. Nas estradas rurais com caixas de contenção verificou-se que em torno de 70% destas encontravam-se inativas, havendo uma deterioração em média de 10% do total de caixas de contenção mensuradas a cada dois anos.

    Full Text Available Este artigo apresenta a visão dos policiais civis e militares do Rio de Janeiro sobre o tema de valorização humana e profissional. A partir da teoria sociológica sobre papéis sociais e de propostas de administração de recursos humanos, o texto tem como parâmetro de análise cinco indicadores qualitativos de valorização: dignidade, realização, reconhecimento, segurança e perspectiva promissora. Do ponto de vista metodológico, o estudo constitui uma análise contextualizada de textos escritos por esses agentes, ao final de um questionário fechado sobre condições de trabalho, de saúde e de vida, realizados numa série de estudos que se iniciaram em 2003 e que vieram a ser material para dois livros sobre as categorias. Os depoimentos foram trabalhados a partir das relevâncias dadas por seus próprios autores, tendo como parâmetro os cinco indicadores citados. Os resultados do estudo mostram que as duas categorias têm sérios problemas de valorização profissional, principalmente quanto aos salários, às condições habitacionais, ao acesso a serviços de saúde e ao apoio institucional e psicológico.This paper presents the viewpoint of civil and military police officers of the State of Rio de Janeiro on the issue of professional and human self-image. It adopts five qualitative indicators as parameter of analysis, namely dignity, achievement, recognition, security and promising prospects, drawn from the sociological theory of social roles and proposals for human resource management. From the methodological standpoint, the study provides a contextual analysis of texts written by these agents at the end of a closed questionnaire on work, health and life conditions, conducted in a series of studies that began in 2003 and provided material for two books about these categories. The analysis considered the relevance given by the authors themselves when they describe their situation, using the five indicators mentioned as parameters

    Following the UK Government's initiative for stimulating renewable energy through the Non-Fossil Fuel Obligation (NFFO), the UK landfill gas industry has more than trebled in size in just 4 years. As a result, UK companies are now in a strong position to offer their skills and services overseas. Ireland, Greece and Spain also resort heavily to disposal to landfill. Particularly rapid growth of the landfill gas market is expected in the OECD-Pacific and NAFTA areas. The article explains that landfill gas is a methane-rich mixture produced by anaerobic decomposition of organic wastes in landfills: under optimum conditions, up to 500 cubic meters of gas can be obtained from 1 tonne of biodegradable waste. Data on the number and capacity of sites in the UK are given. The Landfill Gas Association runs courses to counteract the skills shortage in the UK, and tailored courses for overseas visitors are planned

O primeiro grupo está constituído por mulheres provenientes de um bairro de baixa renda, predominantemente donas de casa, e o segundo grupo inclui funcionárias públicas, estudantes e professoras universitárias, provenientes dos setores médios da sociedade, totalizando quarenta mulheres. A metodologia da pesquisa baseou-se em um questionário estruturado com perguntas abertas de modo a registrar tanto aspectos ligados a variáveis sócio-econômicas e demográficas, quanto dados subjetivos ligados às representações das mulheres sobre o período pós-esterilização. Além de uma série de outros aspectos, tornou-se possível concluir que não existe consenso sobre as conseqüências da esterilização, tendo-se constatado a existência de uma proporção significativa de mulheres esterilizadas (11 principalmente antes dos 30 anos que percebem alterações de saúde após a laqueadura.The objective of this paper is to point out the positive and negative aspects of female sterilization as seen by two groups of sterilized women in Florianópolis, Santa Catarina, Brazil, based on a sociological discussion of their present health status, evaluating the associations that they generally make with the fact that they have been sterilized.

Contudo, crianças surdas vêm enfrentando, na família e na escola, barreiras linguísticas com implicações nas suas possibilidades de inclusão social. Nessa direção, o presente trabalho objetiva analisar o ponto de vista de pais e professores a respeito das interações linguísticas de crianças surdas no âmbito familiar e escolar, considerando o contexto da inclusão. Foram entrevistados doze familiares (quatro pais e oito mães de crianças surdas que frequentam o ensino regular e foi aplicado um questionário junto a doze professores dessas mesmas crianças. Os resultados apontam que nem os familiares nem os professores usam a língua de sinais para interagir com os surdos, gerando interações linguísticas restritas e pouco efetivas. Além disso, percebeu-se que familiares e professores apresentam um desconhecimento acerca da surdez, da língua de sinais e das consequências da surdez para o surdo.Several studies argue that deafness should be currently considered as a difference, specifically regarding linguistic discursive aspects. Nevertheless, at home and at school deaf children have to face linguistic barriers that affect their social inclusion. This study aims to analyze points of view of parents and teachers related to the deaf child's linguistic interactions at home and at school, considering the context of inclusion. Twelve parents (four fathers and eight mothers of deaf children enrolled in regular schools were interviewed and a questionnaire was applied to these children's twelve teachers. The results show that neither parents nor teachers use sign language to interact with these children and that there linguistic interactions were restricted and not very effective.

    Full Text Available A rentabilidade dos bancos é geralmente considerada um fator relevante para garantir a solidez do sistema financeiro, reduzindo os riscos associados aos eventos de insolvência nesse setor. No Brasil, porém, tem havido discussões quanto aos lucros das instituições financeiras que atuam no país, centradas no argumento de que tais lucros seriam supostamente muito elevados, onerando demasiadamente o setor produtivo. Por isso, diversos estudos têm avaliado a estrutura, a evolução e os determinantes do spread bancário, que é considerada a principal variável responsável pelos lucros supostamente anormais. Do ponto de vista metodológico, essas pesquisas têm se concentrado em investigar o spread ex ante das operações com recursos livres e têm utilizado fatores macroeconômicos como variáveis independentes. Este estudo busca identificar variáveis determinantes do spread bancário ex post, privilegiando variáveis explanatórias específicas das instituições, vale dizer, microeconômicas. Na literatura sobre determinantes do spread bancário ex post no Brasil, foi identificado apenas um trabalho anterior, o qual apresentou resultados pouco representativos, devido a um problema de micronumerosidade. Para evitar tal problema, este estudo utiliza dados dos balancetes de janeiro/2000 a outubro/2009 de instituições bancárias com carteira de crédito ativa. Utilizando um modelo de regressão com dados em painel dinâmico, são testadas nove hipóteses, constatando-se que o nível de spread ex post tem relação significativa e: 1. Positiva com o risco de crédito da carteira, com o grau de concentração do mercado de crédito e com o nível de atividade da economia; 2. negativa com a participação relativa da instituição no mercado de crédito. Por outro lado, não foram encontradas relações estatisticamente relevantes entre o spread ex post e: o nível de cobertura das despesas administrativas pelas receitas de prestações de

    This paper reports on natural gas which now appears ready to take a leading role on the world energy stage. Demand for natural gas, and specifically LNG, will be strong throughout the world, particularly in Asia. Indonesia and Malaysia will become much more dependent on natural gas in the Asian market. In Thailand, where remarkable economic growth has been fueled by imported oil and domestically produced natural gas, LNG may soon have to be imported from neighboring countries. The author sees Thailand's imports of natural gas increasing from 1.5 to 4.5 million tons annually. Similarly, Korea's imports of LNG will rise from 2 to 8 million tons between 1987 and 2000. In Japan, energy demand is expected to increase at an even faster rate in the 1990s. Given the opposition to nuclear power generation and growing concern about the greenhouse effect, it is likely that LNG will satisfy a major portion of Japan's increasing demand for energy. Japanese gas companies are studying the possibility of establishing a national pipeline network to move gas beyond metropolitan areas

    This paper analyzes the socioeconomic aspects of solid waste management in Rio de Janeiro. An 'input-output' methodology was used to examine how the secondary product resulting from recycling is re-introduced into the productive process. A comparative profile was developed from the state of recycling and the various other aspects of solid waste management, both from the perspective of its economic feasibility and from the social aspects involved. This was done analyzing the greenhouse gas emissions and the decreased energy consumption. The effects of re-introducing recycled raw materials into the matrix and the ensuing reduction of the demand for virgin raw materials was based on the input-output matrix for the State of Rio de Janeiro. This paper also analyzes the energy savings obtained from recycling and measures the avoided emissions of greenhouse gases

  10. From Rio to Rio: a global carbon price signal to escape the great climate inconsistency

    International Nuclear Information System (INIS)

    Dion, Stephane; Laurent, Eloi

    2012-05-01

    Two decades after the 1992 Rio Conference, we must admit to collective failure in combating human-induced climate change. The problem is not that no efforts have been undertaken, but that these efforts have just not been enough. We cannot escape serious climate disruption - which, to some extent, has already begun - if we keep going down that road. We must change direction, and we must move quickly. To this end, we call in this paper for a fine-tuning of the international negotiations on climate. We propose refocusing these international efforts on negotiating a global carbon price signal, harmonized in principle but flexible in practice, instead of doggedly spending the next few years attempting to convince countries to accept stricter national targets for quantitative reduction of their greenhouse gas (GHG) emissions. We cannot afford to spend the next few years missing the wrong targets. Simply put, we must move away, collectively, from an ineffective logic of constraint to a pragmatic logic of price incentives. The December 2011 Durban Conference proved, once again, that the 'to each their own target' approach does not work. We must instead adopt a 'one price signal for all' strategy. If there were a single reason to improve the current mitigation logic, it would be this evident fact: developing countries, which now account for 60% of emissions worldwide, cannot accept what they perceive as an obstacle to their economic development, when developed countries have been able to get rich on unlimited use of fossil fuel energy. Indeed, in the foreseeable future, emerging economies, particularly China and India with Gross Domestic Product (GDP) annual growth rates of between 8% and 10%, will not accept absolute reduction targets for GHG emissions. On the other hand, these countries might be more open to the idea of a flexible levy of a price per tonne of carbon dioxide, a price from which they would derive revenues, and which their economic

    To investigate whether the image quality of three-dimensional (3D) volume isotropic fast spin echo acquisition (VISTA) magnetic resonance imaging (MRI) of the calcaneofibular ligament (CFL) view is comparable to that of 2D fast spin echo T2-weighted images (2D T2 FSE) for the evaluation of the CFL, and whether 3D VISTA can replace 2D T2 FSE for the evaluation of CFL injuries. This retrospective study included 76 patients who underwent ankle MRI with CFL views of both 2D T2 FSE MRI and 3D VISTA. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of both techniques were measured. The anatomical identification score and diagnostic performances were evaluated by two readers independently. The diagnostic performances of 3D VISTA and 2D T2 FSE were analysed by sensitivity, specificity, and accuracy for diagnosing CFL injury with reference standards of surgically or clinically confirmed diagnoses. Surgical correlation was performed in 29% of the patients, and clinical examination was used in those who did not have surgery (71%). The SNRs and CNRs of 3D VISTA were significantly higher than those of 2D T2 FSE. The anatomical identification scores on 3D VISTA were inferior to those on 2D T2 FSE, and the differences were statistically significant (pT2 FSE for the anatomical evaluation of CFL, 3D VISTA has a diagnostic performance comparable to that of 2D T2 FSE for the diagnosis of CFL injuries.

Será que os mecanismos específicos que caracterizam o funcionamento da globalização são aplicáveis nas mesmas condições nas sociedades que apresentam fortes diferenças como é o caso das sociedades do Norte e do Sul? Diferentes mecanismos ligados ao reforço da competição econômica internacional e às suas conseqüências sobre o sistema de proteção social, ou ainda ligados à difusão de normas e de práticas políticas no contexto da globalização, serão abordados em seguida. De forma mais sistemática, quatro cenários convergência, divergência, hibridação e recomposição das hierarquias internacionais serão apresentados no contexto de uma análise comparativa dos efeitos da globalização nas sociedades do Sul e do Norte.

Al adoptar este punto de vista busco integrar algo de la pasión que mantiene a los choferes en su oficio, y sostengo que la pasión es un elemento explicativo de este modo de vida urbano. De este modo, asumo una visión interna para tomar seriamente lo que los conductores del autotransporte urbano tienen que decir acerca de su ocupación, así mismo exploro la génesis colectiva que induce a los choferes a concederle valor y entrega al “ministerio” del autotransporte. Lo anterior implica conocer las necesidades sociales específicas que invisten su universo y su problemática, acercarse a la estructura en que se desenvuelven, su localización en los espacios sociales en el barrio y la ciudad, así como las trayectorias sociales y disposiciones de quienes participan en este universo profesional tan característico de las ciudades latinoamericanas. Esta perspectiva busca contrastar los testimonios externos más comunes sobre los choferes, los cuales han construido una imagen enteramente negativa del oficio que, sin embargo, nuestra experiencia cotidiana a menudo ratifica.

E-mail: ummaia@usp.br This study aimed to assess the current status of stingless bee beekeeping (meliponiculture in the State of Rio Grande do Norte, Brazil, with the aid of structured questionnaires made during visits to beekeepers. The results were compared with a previous census made in the state and with a similar study from Australia. Meliponiculture in Rio Grande do Norte is still informal and little standardized. The activity has grown in recent years considering the mean number of nests per beekeeper. Most apiaries are formed of up to 50 colonies, usually distributed in the backyards of homes. Twelve species of stingless bees were reared in the state, and the most common was the “Jandaíra” bee (Melipona subnitida, whose honey is considered medicinal. While many beekeepers already know the importance of bees as pollinators, stingless bees are still not used for crop pollination. Compared to a recent analysis of beekeeping in Australia, meliponiculture in Brazil is more traditional, honey is the main product and the number of colonies per beekeeper is much higher. Our results highlight the need to reinforce knowledge about bees and promote specific training aimed at improving and standardizing management practices.

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

Em diversas áreas da indústria moderna, o calcário é utilizado como corretor da acidez do solo. A calagem é uma prática barata, porém ainda é negligenciada quanto ao seu uso, na adoção da técnica, à definição das doses e às formas de aplicação. A briquetagem consiste na aglomeração de partículas finas através de pressão, auxiliada ou não por aglomerantes, permitindo obtenção de produtos compactados, com forma, tamanho e parâmetros mecânicos adequados. A redução de volume do material, além dos benefícios tecnológicos, permite que materiais finos possam ser transportados e armazenados de forma mais econômica. A recente preocupação ambiental, resultando em leis mais rígidas, além da necessidade de aproveitar economicamente os resíduos e as partículas finas geradas no beneficiamento de minérios fez com que a briquetagem voltasse a ser uma importante alternativa para aglomerar valor econômico.

  8. Gas war

    Shiry, J.

    1992-01-01

    The sale of natural gas to California is one of the most complex and contested trade disputes between the USA and Canada. The background and the issues involved are discussed. An oversupply of Canadian gas, combined with USA subsidies for producing coalbed methane and a general oversupply of gas in the USA, have made spot gas prices decline to unexpectedly low levels. California regulators have responded to this situation by trying to secure the lowest possible prices for consumers, thereby causing them to abandon long-standing trade policies with Canada. The main agent of this change is the California Public Utilities Commission (CPUC), whose actions have reduced the value of Canadian exports and Alberta government revenues by at least $250 million annually. CPUC supported buying from a supply pool (Alberta ampersand Southern Gas) since it provided monopoly purchasing power, and CPUC's policy against pipeline expansion produced the limited access to California that the CPUC now cites as evidence of a producer cartel. CPUC has interfered in contracts with Canadian producers in its pipeline access policies, its capacity brokering decision of 1991, and its reasonableness test for past sales. In its haste to force its own view of market results onto existing contractual relationships, the CPUC is not allowing open negotiations to reshape the relationship, and CPUC actions may be generating countermeasures by Alberta that are inappropriate under deregulation. 3 figs

    Consumersfirst Ltd. is reacting to deregulation with a massive advertising campaign. The gas utility is owned by Consumers Gas Energy Inc., and is struggling to hold onto its 35 per cent share of Ontario`s two million residential natural gas buyers. An industry analyst pointed out that deregulation could mean that Consumers` Gas has much to lose: customers, market share, control of the assets and control of the process. The Ontario Energy Board (OEB) however, had specified that Consumersfirst is not to proceed with paperwork to sign up new customers until the OEB issues a draft code-of-conduct that would prevent cross-subsidizing between regulated franchise holders. This has now been done, and several heavyweights such as Calgary-based Suncor Energy Inc., Union Gas of Chatham, Ontario, and the US-based Enron Corp. of Houston, have started campaigns to sign up potential consumers. It is predicted that brand loyalty will be a factor, but in the end, like long distance telephone rates, it will all come down to pricing, and a winning formula is not easy to find.

    TBG - Transportadora Gasoduto Bolivia-Brasil S.A, executes routine maintenance works at the Gas Pipeline Right of Way, seeking its integrity. In the wetlands of Pantanal, near the Paraguay river crossing, the organic-alluvial soil was submitted to the process of subsidence. This process, associated with the river water flow erosion, shrank the soil volume and diminished or extinguished the pipeline land cover. The pipeline was exposed to the environment, and submitted to tension stresses and the risk of low cycle fatigue during the floods. The cathodic protection system also had to be evaluated, specially in the drought. To mitigate the problem, the embankment technique was adopted using sandy soil, reinforced with polyester geo-webs and with woven polipropene geo-textiles. The solution also used geo-webs with soil-cement as protection elements against the degradation of the geo-textiles blankets. Some monitoring works are associated with those interventions: monitoring of cathodic protection; topographical verification of horizontal and vertical displacements of the pipeline; levels of land covering, and rainfalls and flood measurement. The base of the embankment was built with hydraulic transported soil, and at the end consistently supported the gas pipeline. (author)

    Uranium series disequilibrium is useful for dating methods, in which profile sediments can be considered as historical records of anthropogenic events regarding the distribution and impacts of chemical substances on the environment. In this study, 2 deep sediment profiles (about 1 m) were collected, layered at each 3 cm, oven-dried and homogenized. The radiochemical separation of {sup 210}Pb consisted of using hydrobromic acid and an ion exchange resin (DOWEX) for precipitating {sup 210}Pb in the form of lead chromate. After 10 days, the radioactivity was therefore measured by means of the low level gas flow proportional counter, model S5-XLB, from Canberra. Sedimentation rate were obtained by CIC (Constant Initial Concentration) model assumes a constant sedimentation rate throughout the period over which unsupported {sup 210}Pb is measurable. Some sediment profiles were not dated since the percentage of sand was quite high in top layers or a high percentage of organic matter and water in excess were observed in the all sediment samples. {sup 210}Pb geochronology was successfully applied to age nine sediment profiles, in which higher sedimentation rates were observed in the middle portion of the estuarine probably related to shrimp farming impacts. By using geochronology, the detection of human impacts on chemical element distribution could be enhanced in the case of environmental monitoring studies in the Rio Formoso estuarine. (author)

    A gas sensor is described which incorporates a sensor stack comprising a first film layer of a ferromagnetic material, a spacer layer, and a second film layer of the ferromagnetic material. The first film layer is fabricated so that it exhibits a dependence of its magnetic anisotropy direction on the presence of a gas, That is, the orientation of the easy axis of magnetization will flip from out-of-plane to in-plane when the gas to be detected is present in sufficient concentration. By monitoring the change in resistance of the sensor stack when the orientation of the first layer's magnetization changes, and correlating that change with temperature one can determine both the identity and relative concentration of the detected gas. In one embodiment the stack sensor comprises a top ferromagnetic layer two mono layers thick of cobalt deposited upon a spacer layer of ruthenium, which in turn has a second layer of cobalt disposed on its other side, this second cobalt layer in contact with a programmable heater chip.

    Full Text Available This study estimated the water footprint of pigs slaughtered in the municipalities that participate in the Regional Council for the Development of Serra (Corede Serra, in Portuguese, located in the northeast region of Rio Grande do Sul State, in 2014. In order to determine the water footprint, we estimated the water consumed in the production of grains (corn and soybeans used for animal feed, the water used for livestock watering, the water used for cleaning creation areas and the water consumed by animals during the growing and finishing phases. The total water footprint of slaughtered pigs was 0.19825 km3, the largest component of which was water used for the cultivation of grains (99.6%. The municipality of Nova Prata had the largest water footprint of Corede Serra (0.02343 km3 year1, followed by the municipalities of Paraí (0.02187 km3 year-1 and Serafina Corrêa (0.01658 km3 year-1. The municipalities of São Marcos (0.000006 km3 year-1, Bento Gonçalves (0,00002 km3 year-1 and Boa Vista do Sul (0.0004 km3 year-1 had the lowest water footprints, due to low corn productivity associated with the low number of hogs slaughtered. From this assessment, it was found that the management of water resources associated with pig chain production should include water used in the production of feed grain as well as the water used directly in animal husbandry.

    Full Text Available A educação é considerada uma importante fonte de transformação do ser social. Provocações e novos desafios surgem a cada dia em busca de analisarmos se estamos atuando ou não de forma moral e ética. A sustentabilidade e o consumismo são características bem opostas, de um lado empresas que primam pelo progresso, oferecem vagas de empregos e beneficiam seres humanos com suas atividades, do outro, uma nova educação, dotada de preocupações com a preservação ambiental. Considerado um dos assuntos mais comentados na atualidade, a educação para sustentabilidade está intrinsecamente ligada à solidariedade, respeito e afetividade e precisa estar conectada a três pilares: prosperidade econômica, respeito ao meio ambiente e proteção social. Para isto, é necessário que as pessoas substituam o pensamento capitalista consumista, mantendo a sustentabilidade. Esta pesquisa teve o objetivo de identificar acontecimentos atuais provocados por uma mineradora no município de São João da Boa Vista e o quanto a conscientização pela Educação para a Sustentabilidade pode proporcionar para a localidade e humanidade. Investigouse a Lei Orgânica e Legislação Municipal a fim de evitarem a ação da mineradora e manter, sem maiores danos, o turismo local e regional.   Education is considered an important source of transformation of social being. Provocations and new challenges arise every day in order to analyzy whether or not we are acting with morals and ethics. Sustainability and consumerism are quite opposite characteristics on the one hand companies that strive for progress, offer job openings a new education, endowed with concerns over environmental preservation. Considered as one of the most discussed subjects currently, education for sustainability is intrinsically linked to solidarity, respect and affection and has to be connected to three pillars: economic prosperity, environmental respect and social protection.

    Full Text Available A contribuição do mundo muçulmano para uma nova ordem econômica internacional baseia-se na aplicação renovada da lei islâmica, a shari'ah, nas modernas transações econômicas e financeiras. No que se refere às atividades financeiras, as medidas devem ser vistas como parte integral de uma tentativa de desenvolver o ideal islâmico na sociedade e na economia, com base nos princípios islâmicos da justiça social e humana. O acesso ao banco islâmico envolve – além de suas implicações religiosas – uma relação conceitualmente diferente entre atividade financeira e atividade econômica. A ligação emprestador/tomador de empréstimo é substituída pelo risco/distribuição equitativos entre o capital e o empresário. A consequência principal dessa abordagem diferente da economia islâmica é a proibição de pagar ou cobrar juros. A palavra zakat significa purificação e crescimento. Cada muçulmano deve calcular, anualmente, a sua zakat que, em geral, corresponde a 2,5% dos seus rendimentos. As pessoas pobres não precisam pagar zakat, visto que um dos objetivos desse dever religioso é, precisamente, ajudar os mais pobres. No passado, a maior parte dos países muçulmanos cobrava a zakat, mas a prática foi abandonada. Segundo o Islam, toda riqueza é oriunda de Allah. Aqueles que tiveram a sorte de beneficiar da sua riqueza devem, por sua vez, apoiar os membros mais desfavorecidos da comunidade muçulmana (a umma. O não pagamento do zakat é entendido como um pecado que será julgado no Dia do Juízo Final (Yaum al-Qiyamah. Esse tributo é, também, visto como forma de purificação do crente.

    Full Text Available OBJETIVO: Avaliar a toxicidade ocular do colírio de iodo-povidona a 2,5% e a 0,5% sobre a superfície ocular, na regeneração do epitélio corneal e as alterações histopatológicas da córnea. MÉTODOS: Realizaram-se estudos experimentais consecutivos em coelhos albinos, nos quais se fez a ablação do epitélio de uma área circular central da córnea de 6,5 mm de diâmetro. Em cada experimento foram utilizados 20 animais (40 olhos, sendo que no olho direito foi instilado o colírio de iodo-povidona (caso e no olho esquerdo água destilada (controle, em intervalos de uma hora, durante três dias consecutivos. Durante o experimento, os animais foram submetidos a exames biomicroscópicos diários para avaliação da superfície córneo-conjuntival e realização de fotografias seriadas da área sem epitélio, corada com fluoresceína, para medida da área projetada da lesão com auxílio de analisador de imagem computadorizado. No final do experimento, os animais foram sacrificados para avaliação histopatológica das córneas. RESULTADOS: O colírio de iodo-povidona a 2,5% comprometeu a regeneração epitelial, causou conjuntivite em 100% dos olhos, com produção de secreção de aspecto mucoso em 80%, ceratite ponteada em 40% e edema estrômico leve em 10% dos casos. Os achados histopatológicos foram úlcera de córnea, degeneração hidrópica das células endoteliais e infiltrado inflamatório com predomínio de eosinófilos em 100% dos casos. Nos olhos em que se instilou iodo-povidona a 0,5%, assim como nos controles, observou-se completa regeneração da lesão epitelial (p<0,001 após 72 horas do início do experimento. Do ponto de vista histopatológico, epitelização normal em todos os casos e controles, em apenas um caso observou-se discreto infiltrado de leucócitos perilímbicos. CONCLUSÃO: A toxicidade ocular do colírio de iodo-povidona é dependente da concentração da solução, sendo que o colírio a 2,5% mostrou

    Full Text Available La presente evaluación hidrogeológica tiene el propósito de apoyar a los municipios de Tecoripa y Suaqui Grande para resolver la problemática que enfrentan respecto a la escasez de agua, reflejado, en el abatimiento de sus acuíferos y en los bajos escurrimientos superficiales. La evaluación incluyo información previa y genero nuevos datos sobre geología, geofísica, hidrología superficial e hidrogeología. Para conocer las condiciones del subsuelo, se aplicaron las técnicas de prospección geofísica de resistividad eléctrica y gravimetría. Se elaboró un modelo de 3 a 5 capas, siendo la cobertura aluvial del Rio Tecoripa la más importante, para el almacenamiento de agua subterránea desde el sitio La Cortina hasta Suaqui Grande, con espesores que varían de los 4.0 a los 20.0 m. El basamento está representado por el Grupo Baucarit, con espesores de decenas a cientos de metros, es improductivo desde el punto de vista geo hidrológico. Los cálculos hidrológicos muestran que la evapotranspiración representa el 87% de la lluvia, el escurrimiento el 12% y el resto ocurre como infiltración o recarga al acuífero. Se concluye que el volumen infiltrado no es suficiente para los usos que se realizan en el Acuífero del Rio Tecoripa, por lo que se recomienda se realicen obras hidráulicas de recarga artificial.

    Full Text Available A precipitação no Nordeste brasileiro apresenta grande variabilidade, motivo pelo qual o monitoramento dos períodos secos e chuvosos se faz necessário, haja vista ser imprescindível para garantir o gerenciamento adequado dos recursos hídricos. Neste sentido foi utilizado o Índice de Anomalia de Chuva a fim de monitorar os períodos secos e chuvosos e suas intensidades. Utilizaram-se dados de 31 postos distribuídos ao longo da Bacia Hidrográfica do Rio Mamanguape com série histórica de 18 anos (de 1994 a 2011. Dentro de cada ano foram observados dois períodos distintos, um período úmido, que vai de março a agosto e um período seco, que se estende de setembro a fevereiro. Esta pesquisa apresenta a climatologia espacial da bacia, a qual evidenciou três regiões distintas, sendo a primeira a região leste, a segunda é a região central e a terceira é a região oeste. Por fim, foram efetuadas projeções de redução e aumento da precipitação em 20% sobre o valor atual obtido a partir da série histórica, como recomendado pelo IPCC (2001; foi possível, desta forma, projetar futuras variações climáticas na região da bacia as quais são passíveis de alterar, de maneira significativa, seu aporte hídrico.

  1. Entre vidas objetificadas e vítimas da escravização: a trajetória das ossadas do Cemitério dos Pretos Novos, no Rio de Janeiro

    Directory of Open Access Journals (Sweden)

    Simone Pondé Vassallo

    Full Text Available Resumo Nos últimos anos, diversas iniciativas no Brasil e no mundo apontam para um novo enquadramento da escravidão que procura trazer à tona o ponto de vista dos escravizados. Elas são elaboradas em torno de uma nova moralidade que denuncia o processo de vitimização a que foram submetidos. No entanto, a construção dessas novas narrativas é permeada por conflitos e ambiguidades. Partindo de uma etnografia sobre as ossadas do sítio arqueológico Cemitério dos Pretos Novos, tento trazer à tona a multiplicidade de atores e representações que transcendem e ressignificam o processo de vitimização. Com isso, procuro iluminar a complexidade da construção contemporânea da categoria da vítima, em particular as vítimas da escravização no Brasil.

    Full Text Available Promover o protagonismo de comunidades no processo de desenvolvimento do turismo local tem estimulado a constituição de incubadoras de empreendimentos solidários. Tal processo amplia a intervenção social, politica e econômica do poder público e fortalece a organização comunitária para responder as questões de geração de trabalho e renda, com base em experiências solidárias e cooperativas. Nesse artigo são analisadas as ações da Incubadora Tecnológica de Cooperativas Populares (ITCP/UFPR no processo de formação da cadeia produtiva do turismo comunitário, em Barra do Superagüi, município de Guaraqueçaba, Paraná. Metodologicamente compõe-se de estudo de caso, com observação direta e entrevistas com gestores do projeto. Os resultados apontam indícios da incubação de empreendimentos turísticos contribuírem para fortalecer a comunidade local com vistas ao desenvolvimento territorial, e na articulação de ações do projeto com políticas públicas de economia solidária e do turismo, que surgem em comunidades, que desejam oferecer produtos, serviços e atrair visitantes.

    Full Text Available O presente artigo apresenta uma reflexão sobre o papel da Cidade na sua relação com o Turismo, quando a mesma não esteja associada a destino de montanha ou mar. Analisa-se a ascensão do turismo de massa, em simultâneo a desqualificação da cidade industrial, que levam a consagrar a viagem como evasão e fuga do urbano, e a busca de espaços tidos como paradisíacos, junto à natureza. Propõe-se, ainda, utilizar Michel Maffesoli, em especial na sua teorização sobre imaginário ou imaginal, como ele também refere, e o conflitual, segundo o mesmo teórico, para com eles analisar a Cidade e o Urbano, a primeira vista enquanto espaço físico concreto e, o segundo, enquanto o imaginal, o complexo das relações socioculturais que alimentam o imaginário de Cidade. Assim como o pastoral está para o campo, o Urbano estaria para a Cidade. Entre os sujeitos que contribuem para essa construção, papel preponderante é desempenhado pela mídia. No caso do Turismo, a presente análise reporta a contribuição de uma publicação especializada, a Revista Viagem e Turismo, na construção do imaginário de cidade turística. No caso da publicação identifica-se o imaginário de cidade turística associada ao paraíso em destinos identificados pela presença marcante da natureza. Tourist City and its Imaginary: The Specialized Press This article presents a reflection on the role of the City regarding tourism, when it is not associated to a mountain or ocean destination. It is analyzed the mass tourism rise, simultaneously with the industrial city disqualification, which lead to devote the trip as evasion and escape from the urban area, and the search after places said to be paradisiacal, close to the nature. It is also proposed to use Michel Maffesoli, especially in his theory about the imaginary or imaginal, as he also says, and the conflitual, according to the same theory and to use them to examine the City and the Urban, at first as concrete

    Full Text Available A presente pesquisa objetiva uma aproximação música x psicanálise, considerando nossa condição de falantes dotados de um inconsciente que encontra na  arte, na música,  uma atividade de expressão e produção de sentido. Atentando aos limites impostos por cada uma dessas ciências procura-se refletir o processo de subjetivação, partindo do entendimento de música como alteridade e autonomia, e o processo de criação como auto-realização, relacionado com pulsão e desejo. Justifica-se a pesquisa haja vista que psicanálise e música  lêem o homem em sua vida cotidiana e em seu caminho histórico; ambas são “receptáculo daquele lugar de opacidade intransponível que é o imaginário” (Metz,1980; ambas são infiltradas pelo inconsciente e envolvem expressões e emoções. O suporte teórico é encontrado em Freud e Maynard Solomon. O recorte musical adotado é Beethoven e  a metodologia, bibliográfica e “interpretativa”. Uma das conclusões a que se chega é que, tanto na psicanálise quanto na música, é possível a percepção de uma “outra fala” ampliando os limites da compreensão e experiência humana.

    Full Text Available A qualidade percebida e a satisfação dos clientes são elementos essenciais para a competitividade das instituições bancárias. Assim, é importante identificar os fatores que determinam a percepção de qualidade e satisfação do ponto de vista dos clientes que utilizam esse tipo de serviço. O objetivo deste artigo é a construção de um modelo de relacionamento entre os determinantes de satisfação de clientes e a identificação dos principais atributos que afetam a qualidade percebida dos clientes de serviços bancários. Para isto, foram aplicadas duas pesquisas descritivas. Na primeira fase das pesquisas, utilizou-se a abordagem proposta por Tinoco e Ribeiro (2007 para identificar as relações entre determinantes e construir o modelo de satisfação de clientes. Na segunda fase, foram levantados e hierarquizados os principais atributos de qualidade percebida do ponto de vista dos clientes. Entre os resultados obtidos destacam-se como principais determinantes da satisfação de clientes a confirmação de expectativas e a qualidade percebida. Entre atributos mais importantes que afetam a qualidade percebida podem ser citados: funcionários com conhecimento e habilidade devidos, serviço feito corretamente na primeira vez, tarifas bancárias baratas, transparência e lealdade nas negociações, e presença de funcionários que buscam tornar o serviço mais ágil.Perceived quality and customer satisfaction are essential elements for competitiveness of banking institutions. Therefore, it is important to identify customers' view of banks about drivers of quality perception and satisfaction. This paper presents a relationship model of determinant factors of satisfaction and the identification of key quality attributes for bank services. The model was built conducting two customer surveys. Firstly, the approach proposed by Tinoco and Ribeiro(2007 was applied to identify the relationship among the determinants and to build a satisfaction

    Full Text Available Devido ao constante avanço tecnológico, uma grande quantidade de aparelhos é descartada por obsolescência tecnológica ou defeitos. Isto acarreta a contaminação do solo e do lençol freático, além de representar perda econômica pois as PCI (placas de circuito impresso dos telefones celulares são ricas em metais pesados e alguns metais valiosos. Com o objetivo de conhecer melhor a composição e concentração destas PCI de modo a otimizar os processos de reciclagem, foi realizada a caracterização das PCI através da digestão em água régia e da utilização das técnicas de DRx (difração de raios x e FRx (espectrometria de fluorescência de raios x. Os resultados proporcionaram conhecimento suficiente a respeito da composição e concentração dos principais metais das PCI. A presença de ouro, prata e cobre chama a atenção para o potencial econômico destes resíduos. Estudos são necessários para desenvolver os processos mais adequados com vistas a concentrar estes metais e viabilizar sua reciclagem.

    Few data are available on the dynamic of radon in the air for tropical climate conditions. The strong influence of the climatological characteristics on the transport of gases and particulates in air makes not adequate the use of data obtained at regions with different climate. Outdoor and indoor measurements of radon equilibrium equivalent concentrations (EEC) have been done for one-year period in Rio de Janeiro. Continuous measurements were performed using a radon monitor with an alpha spectrometry detector. Pluviometric index, temperature and humidity were registered. The paper presents the long term behaviour of outdoor radon equilibrium equivalent concentration results, their correlation with temperature and the influence of the pluviometric index. Maximum values were obtained during winter and minimum in summer, strongly influenced by the rain. A strong inverse correlation with temperature was found. (author)

    Full Text Available A geração de energia elétrica no Brasil é predominantemente renovável, com a geração interna hidráulica sendo superior a 74% do total de sua matriz energética. O racionamento de energia elétrica ocorrido em 2001, devido à falta de chuvas, levou o país a incrementar a participação de fontes alternativas de energia. Esta necessidade por novas fontes de energia faz com que as potencialidades regionais sejam aproveitadas, o que configura a mudança do modelo de geração, passando de geração centralizada para geração distribuída. Dentre as fontes alternativas de energia, a solar apresenta-se como uma fonte bastante promissora para o Brasil, tendo em vista que a maior parte do seu território está localizada próximo à linha do equador, o que acarreta em um dia de maior duração solar. O Rio Grande do Norte (RN tem um dos maiores índices de incidência solar do território brasileiro, o que o torna apto a receber investimentos para a instalação de usinas solares fotovoltaicas. Este artigo analisará o potencial de geração da energia solar fotovoltaica no RN através de medições solarimétricas realizadas em Natal, capital do estado.

Sixteen animals were equally distributed in two groups: SV and CV. All surgical procedures were commenced on left lateral recumbency (LLR and 75 minutes later the animals were repositioned on right lateral recumbency (RLR. Arterial blood gas analyses were performed at 30 and 75 minutes after each recumbency (M1 and M2 for LLR and M3 and M4 for RLR. Hypercapnia (PaCO2 >45mmHg, respiratory acidosis (pH <7.35, and significant decrease in PaO2 after 75min of change in body position (M4: 205.8±124.7mmHg in comparison to PaO2 values before the change of position (M1: 271.8±84.8mmHg were observed during SV. When compared to the SV group, CV resulted in significantly higher PaO2 levels (52 to 96% increase. It was concluded that the change in the body position in spontaneously ventilating halothane-anesthetized horses causes impairment in arterial oxygenation. The use of CV since the beginning of anesthesia prevents the respiratory acidosis and maintains arterial oxygen levels that are closer to values expected during the use of 100% O2.

    Bortezomib-melphalan-prednisone (VMP) is a standard-of-care for previously untreated, transplant-ineligible multiple myeloma (MM). Here, we compared outcomes between VMP regimens in the VISTA trial (9-cycle VMP schedule, including 4 cycles of twice weekly bortezomib) and the PETHEMA/GEM05 trial (less intensive 6-cycle VMP schedule with 1 cycle of twice weekly and 5 cycles of weekly bortezomib, then bortezomib-based maintenance). A total of 113 patient pairs matched by propensity score (estimated using logistic regression and incorporating eight exposure/outcome-related parameters) were included in this retrospective analysis. Median cumulative bortezomib dose was higher in PETHEMA/GEM05 than VISTA (49.6 vs 37.0 mg/m 2 ); median dose intensity was lower (2.0 vs 5.1 mg/m 2 /month). Median progression-free survival (PFS) and time-to-progression (TTP) were significantly longer in PETHEMA/GEM05 than VISTA (PFS, 30.5 vs 20.0 months, p = 0.0265; TTP, 33.8 vs 24.2 months, p = 0.0049) after a median follow-up of 77.2 and 26.0 months, respectively. Median overall survival (OS) was similar (61.3 vs 61.0 months, p = 0.6528; median follow-up, 77.6 vs 60.1 months). Post-induction complete response rate was lower in PETHEMA/GEM05 than VISTA (19 vs 31 %; p = 0.03318); on-study (including maintenance) rate was similar (30 vs 31 %; p = 0.89437). This analysis suggests that the less-intensive PETHEMA/GEM05 VMP regimen plus maintenance may improve PFS and TTP, but not OS, compared with the VISTA VMP regimen. NCT00111319, NCT00443235.

  11. Oils; gas

    Energy Technology Data Exchange (ETDEWEB)

    Day, D T

    1922-09-18

    Oils and gas are obtained from shale or oil-bearing sand by immersing the shale in and passing it through a bath of liquid oil, cracking the oil-soaked shale, and condensing the vapor and using the condensate to replenish the bath, preferably by passing the gases and vapors direct into the oil-bath container. Shale is fed continuously from a hopper to a bath of oil in an inclined chamber, is carried to the outlet by a conveyer, and through cracking tubes to an outlet pipe by conveyers. The gases and vapors escape by the pipe, a part condensing in the chamber and a run-back pipe and replenishing the bath, and the remainder passing through a condensing tower and condenser connected to reservoirs; the gas is further passed through a scrubber and a pipe to the burner of the retort. The oil condensed in the chamber overflows to the reservoir through a pipe provided with an open pipe to prevent siphoning. The conveyers and a valve on the pipe are operated by gearing. The operation may be conducted at reduced, normal, or increased pressure, e.g., 70 lbs. The temperature of the retort should be about 900 to 1400/sup 0/F, that of the inside of the tubes about 550 to 700/sup 0/F, and that of the chamber about 300/sup 0/F. The chamber and pipe may be insulated or artificially cooled.

    2010-06-01

    Full Text Available A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belonging to 28 families, most of which from unconsolidated substrates, was identified. The shellmound species composition does not differ from the present-day composition. All recorded species are characteristic of a wide transition zone between the south of the states of Espírito Santo (21°S and Rio Grande do Sul (32°S. Thus, the data show little evidence of evolution in the composition, richness,and biodiversity distribution patterns of mollusks in the Rio das Ostras region. Likewise, a reconstitution of the paleoenvironment from the functional characteristics of the shellmound species indicates that the locality's geomorphology and climate remained largely unchanged in the last 4,000 years BP.

    2008-11-01

    Full Text Available Atualmente notamos uma explosão de livros, revistas e programas de televisão voltados para temas como carreira, negócios e empreendedorismo. Enquanto há, de um lado, uma literatura acadêmica que estuda o empreendedorismo como um tipo de ação econômica e o empreendedor como um ator social a quem corresponde um tipo de prática ligada à liderança e à inovação, há também , de outro, uma literatura não acadêmica que faz do empreendedorismo um conjunto de princípios ideais de bom comportamento e que, a partir desse conjunto, estabelece prescrições normativas para aqueles que desejam tornar-se empreendedores. Diante disso, o presente artigo pretende discutir a construção de uma ideologia que traz, na noção de empreendedor, o empresário como um ator social imbuído de uma conotação ética. As histórias de sucesso de empresários aparecem como um rico material empírico para a compreensão da construção e da difusão de uma ideologia na qual a noção de empresário vai sendo ressignificada. No centro desse processo, encontram-se os "gurus" da administração, os quais, por meio de seus sucessos editoriais, da internet e da grande mídia, difundem uma série de conselhos práticos e assumem a função de empreendedores morais do empreendedorismo. Conclui-se que, por meio desses conselhos e da divulgação dos casos exemplares de sucesso (assim como foi com o protestantismo, no início do capitalismo, formam-se sujeitos com disposição para atuar economicamente e de forma reconhecida como boa e justa. O empreendedorismo pode, portanto, sob esse ponto de vista, ser visto como uma ideologia do capitalismo atual que surge para garantir a adesão e a legitimidade a atividades antes não valorizadas.

  15. Políticas da Terra: existe um novo discurso ambiental pós Rio +20?

    Juliana Wenceslau

    Full Text Available Políticas públicas envolvem a construção de significado através de discursos, que caracterizam redes semânticas complexas, articulando diferentes pressupostos, conceitos e hipóteses. O objetivo deste artigo é contribuir para o debate sobre a evolução recente da política ambiental, indagando em que medida os debates que marcaram a Rio +20 caracterizam uma ruptura com os quatro discursos predominantes na política ambiental ao longo dos últimos 40 anos. São eles: sobrevivencialismo, resolução de problemas, sustentabilidade e radicalismo verde. Esses discursos são diferentes em seus pressupostos ontológicos (mais realista ou mais nominalista; nas suposições sobre a natureza dos relacionamentos com o meio ambiente (baseados em competição ou em cooperação; na perspectiva que assumem sobre os atores (individualistas ou coletivistas; fortes ou fracos; e nas metáforas que utilizam para defender seus pontos de vista (DRYZEK, 1997. Algumas perguntas também são colocadas para avaliar o impacto e plausibilidade do discurso: que política é associada a ele; seu efeito nas políticas públicas e nas instituições; os argumentos dos críticos; e as falhas reveladas pelas evidências e argumentos. A análise do discurso da Rio +20 foi baseada no documento final da conferência "The Future We Want". Concluímos que os debates da conferência agregam dois grandes discursos: resolução de problemas e sustentabilidade. Alguns efeitos antecipados da Rio +20 são: a melhoria das estatísticas ambientais; aumento de empregos ligados à economia verde; e adoção de políticas regulatórias que modifiquem os preços relativos do uso dos recursos e internalizem os custos das externalidades ambientais.

    Full Text Available La diseminación del uso de computadores y del desarrollo de softwares ocasionó modificaciones intensas en los procedimientos de las oficinas contables a partir de la década de 1990, siendo que el impacto de esas innovaciones, desde el punto de vista de los profesionales del área contable, no ha sido debidamente analizado. Por esa razón, este estudio tiene como objetivo general evaluar los impactos causados por la innovación tecnológica en las oficinas de contabilidad de Rio Grande do Sul, a partir de 1990. Desde el punto de vista metodológico, la pesquisa es exploratoria y los datos fueron colectados a partir del envío de un cuestionario estructurado, survey, utilizándose una escala de cero a diez. La muestra no probabilística fue compuesta por 408 que respondieron a la encuesta y los análisis efectuados a partir de estos cuestionarios se dieron por medio del análisis factorial del tipo “R”. Entre los resultados, destacan la percepción de los profesionales contables encuestados que respondieron a la pesquisa de que la innovación tecnológica permitió mayor agilidad en la prestación de los servicios, mejorar la calidad de la información y con informaciones más útiles para los gestores, siendo que el elemento que más impactó a las oficinas fue el advenimiento de internet. Sin embargo, esas innovaciones trajeron más complejidad en la realización de las tareas de las oficinas y la necesidad de captación de los empleados.

    Maria Antonieta Ribeiro Marcolino

    2017-04-01

    Full Text Available Desde a década de 1960 defende-se internacionalmente a promoção das mesmas condições de acesso ao conhecimento e exercício da cidadania a indivíduos de diversas etnias, classes sociais, níveis de instrução, necessidades especiais e deficiências. No Brasil, a questão dos direitos das pessoas com deficiência foi enfatizada a partir da Constituição de 1988, que em seus Artigos 206 e 208 dispõe a igualdade de acesso ao ensino para todos. Sendo as bibliotecas escolares uma extensão das instituições de ensino, também as abrangem as políticas de educação inclusiva. No cenário da inclusão na biblioteca escolar, a atuação do bibliotecário é fundamental, pois esse profissional é o responsável pelo acolhimento do usuário. Este trabalho tem por objetivo fazer uma observação sobre a presença de usuários especiais na biblioteca escolar, e o profissional da informação frente às adequações necessárias com relação ao ambiente, acervo e atendimento da biblioteca escolar, de modo a promover um espaço aberto a todos. Por se tratar de uma pesquisa exploratória, foi realizada a partir de revisão bibliográfica de livros, teses, artigos e sites relacionados com o tema abordado, no intuito de analisar o ponto de vista de vários autores, principalmente das áreas de Biblioteconomia e Pedagogia, a fim de obter referencial teórico para firmar as ideias propostas por este trabalho. Conclui-se que, com o esforço e empenho do profissional da informação, as bibliotecas escolares podem estabelecer parceria com outras instituições e criar atividades para dar os primeiros passos para a construção de um ambiente inclusivo sem depender exclusivamente das iniciativas de suas mantenedoras.

    Full Text Available Neste artigo consideramos os problemas ambientais globais dentro do conceito de limiares planetários, em convergência com os últimos avanços das ciências naturais. Nesse contexto, nosso objetivo é explorar o papel do Brasil na governança do espaço de operação seguro para a humanidade, avaliando como o país complementa o enorme capital ambiental físico que possui com ações políticas específicas orientadas para uma economia verde de baixo carbono (EVBC, tanto no âmbito doméstico quanto no internacional. Para atingir essa meta, em primeiro lugar discutimos conceitualmente a economia verde de baixo carbono como paradigma de desenvolvimento compatível com um espaço de operação seguro para a humanidade; em segundo lugar, analisamos a Rio+20 pelo prisma da governança global dos limiares planetários e pela atuação brasileira na Cúpula; e finalmente fazemos um diagnóstico da situação do Brasil em relação ao novo paradigma de desenvolvimento. Como conclusões da análise, destacamos a crescente distância entre a aceleração dos problemas da interdependência - especialmente a definição de um espaço seguro de operação para a humanidade - e os mecanismos globais de governança existentes, derivada de um sistema internacional bloqueado e dominado por forças conservadoras. O resultado frustrante da Rio+20 é evidência clara dessa defasagem. Nessa dinâmica, o Brasil tem o potencial para ser um ator central da governança dos limiares planetários, por seu vasto capital ambiental físico. No entanto, o mínimo avanço da EVBC no país degrada essa capacidade de agência, e o torna uma potência ambiental subdesenvolvida (underachiever environmental power.

Através de fontes primárias e análise documental, a pesquisa desenvolve interpretações sobre as influências paternas de caráter moral, cultural, intelectual e profissional que marcaram a primeira geração da família Palmério no Brasil e, particularmente, condicionaram as experiências que mais tarde seriam ressignificadas na obra literária e na trajetória pessoal de Mário Palmério. Notamos que as permanentes viagens a trabalho do pai e as suas diversas atividades profissionais favoreceram uma consciência familiar das particularidades da região. Essa experiência favoreceu a criação de vínculos econômicos, políticos e afetivos com a cultura regional e estimulou nos filhos um profundo conhecimento histórico e geográfico do Oeste mineiro. Além disso, o pai parece ter exercido uma profunda influência sobre os filhos no que diz respeito ao gosto pela política regional. O artigo desenvolve a hipótese de que todas essas experiências foram elementos presentes na formação de Mário Palmério e, mais tarde, apareceriam de modo explícito em sua literatura marcada pela descrição da natureza, do cotidiano e das intrigas políticas regionalistas. Palavras-chave: Regionalismo; Literatura regionalista; Literatura mineira; Mário Palmério; Vila dos Confins; Chapadão do Bugre.

    International Nuclear Information System (INIS)

    2008-01-01

    The two volumes of the Energy prospects of France at the 2020-2050 vista present the works carried out by the Energy commission, implemented in May 2006 by the Centre of Strategic Analysis and gathering the different actors in concern: representatives, social partners, national and European administrations, operators and industrialists, consumer associations, research organizations, etc.. The first volume is a synthesis while this second volume reprints the integral content of the five working group reports. This collective work fits inside a series of studies that the public authorities have periodically launched on the energy question. They have led to the elaboration of energy policies, still dominated by the hydrocarbon prices: ambitious and rigorous during high price eras, non-obstructive and relaxed during low price eras. Todays, the global warming dominates the energy policy. In this context, a large-scale and permanent new policy has become mandatory to reduce as quickly as possible the CO 2 emissions linked to the satisfaction of energy needs. It must definitely fit with the European framework as well. The Energy Commission recommends that France prevails upon the European Union to adopt a highly voluntaristic policy of greenhouse gases abatement at the 2050 prospects based on a fair share among the member states of the efforts to be achieved. This document includes a prospective analysis of the geopolitical situation, evaluates the technological efforts to come and lists some consistent action proposals for France and the European and national scale.

    Full Text Available La deficiencia nutricional de ciertos minerales como el hierro y zinc afectan a la población a escala mundial con graves efectos sobre la salud dependiendo fundamentalmente del grado de incidencia y de la magnitud de la deficiencia. La fortificación de alimentos ha resultado ser la estrategia más efectiva para corregir esta situación con inconvenientes que radican no solamente en la elección del alimento a utilizar como transporte para dichos nutrientes sino también en la correcta elección del compuesto a utilizar como fortificante ya que en general aquellos compuestos que poseen una adecuada biodisponibilidad presentan cambios en las características sensoriales de los alimentos fortificados poco aceptables para su consumo. Los compuestos inertes, que poseen propiedades optimas desde del punto de vista tecnológico poseen una baja absorción que los convierte en compuestos nutricionalmente poco útiles. En este trabajo se discute con mayor detalle estos aspectos con el fin de llegar a un entendimiento más profundo de la problemática antes mencionada.

In this work, we compared planned 3D dose distribution with measured 3D dose distribution using a novel normoxic polymer gel dosimeter (TENOMAG) and a commercial cone-beam optical CT scanner (VISTA{sup TM}, Modus Medical Devices, Inc., London, ON, Canada) to verify the 3D dose distribution in intensity-modulated radiation therapy (IMRT) prostate case. And we developed {sup P}DRESS using the Xelis Flatform which is developed by INFINITT Corporation is used to display the 3D dose distribution by loading the DICOM RT Data which is exported from RTP and optical-CT reconstructed VFF file. Data analysis is achieved by comparing the RTP data with the VFF data using profile, gamma map, and DTA. The profiles showed good agreement between RTP data, gel dosimeter, and gamma distribution and the precision of the dose distribution is within {+-} 5%. The results from this study show that there are no significantly discrepancies between the calculated dose distribution from treatment plan and the measured dose distribution from a TENOMAG gel scanned with an optical CT scanner. The 3D dose evaluation software ({sup P}DRESS) which is developed in this study evaluates the accuracy of the three dimensional dose distributions.

    A numerical ground-water model was developed to simulate seasonal and long-term variations in ground-water flow in the Sierra Vista subwatershed, Arizona, United States, and Sonora, Mexico, portions of the Upper San Pedro Basin. This model includes the simulation of details of the groundwater flow system that were not simulated by previous models, such as ground-water flow in the sedimentary rocks that surround and underlie the alluvial basin deposits, withdrawals for dewatering purposes at the Tombstone mine, discharge to springs in the Huachuca Mountains, thick low-permeability intervals of silt and clay that separate the ground-water flow system into deep-confined and shallow-unconfined systems, ephemeral-channel recharge, and seasonal variations in ground-water discharge by wells and evapotranspiration. Steady-state and transient conditions during 1902-2003 were simulated by using a five-layer numerical ground- water flow model representing multiple hydrogeologic units. Hydraulic properties of model layers, streamflow, and evapotranspiration rates were estimated as part of the calibration process by using observed water levels, vertical hydraulic gradients, streamflow, and estimated evapotranspiration rates as constraints. Simulations approximate observed water-level trends throughout most of the model area and streamflow trends at the Charleston streamflow-gaging station on the San Pedro River. Differences in observed and simulated water levels, streamflow, and evapotranspiration could be reduced through simulation of climate-related variations in recharge rates and recharge from flood-flow infiltration.

Perón, conduce los destinos de la sociedad argentina. La redistribución del ingreso marca los perfiles de la Nueva Argentina, la que a través de un Estado dirigista y planificador propone poner la economía al servicio de la “justicia social”. En ese contexto y sustentado por un discurso de confrontación que tiene como contrincantes al pueblo y a la oligarquía, el Estado populista se convierte en vocero de los reclamos y necesidades de los trabajadores, de los descamisados. Ellos son los protagonistas de la era peronista y el Estado su vocero. Este estudio analiza, a partir del discurso, las definiciones que el gobierno peronista formula acerca de la pobreza y de los pobres; precisa los medios que propone el Estado para contrarrestar la pobreza y formula una valoración de las connotaciones políticas que se otorga al concepto. El objetivo es hacer un balance del significado de la pobreza vista desde la esfera del poder de un gobierno nacionalista y popular y hacerlo a la luz del análisis histórico.

    Full Text Available Este estudo defende que o comportamento aleatório pode tornar-se legítimo objeto de estudo de uma ciência do comportamento. Analisamos inicialmente algumas considerações que B. F. Skinner formulou sobre o comportamento aleatório em suas Contingências do Reforço. Segundo Skinner (1969/1975, o comportamento aleatório "não apresenta interesse como processo de comportamento". Apresentamos uma rigorosa definição de "comportamento aleatório". Sustentamos que o comportamento aleatório pode constituir objeto de análise funcional, examinando alguns estudos empíricos que se têm conduzido sobre o comportamento aleatório. Apresentamos ainda algumas dificuldades empíricas e teóricas que podem afetar as investigações nessa área. Concluímos que o comportamento aleatório é um fascinante e importante tópico para uma completa ciência do comportamento.

Foram consideradas nesta avaliação as seguintes dimensões: cognitiva, relacional, organizacional e profissional; vistas também sob o ponto de vista das equipes de saúde da família. Tendo em vista as críticas apontadas pela literatura quanto às limitações metodológicas em estudos que avaliam a satisfação de usuários, notadamente vieses ligados à desejabilidade social ou à redução do processo subjetivo de avaliação a respostas do tipo sim/não em questionários fechados, privilegiamos neste caso estratégias metodológicas de cunho etnográfico. A partir da técnica de grupos focais, os usuários expressaram sua percepção sobre o programa e os serviços oferecidos pelas equipes, ao tempo que revelavam suas necessidades e expectativas de satisfação das mesmas.The present study consists of a qualitative evaluation of user satisfaction in the areas covered by the Family Health Program, which are located within five municipalities of Salvador (Bahia, Brazil. During the evaluation, the following dimensions were taken into account: cognitive, relational, organizational and professional; the family health teams' point of view was also considered. Owing to criticism directed in the literature towards the methodological limitations of studies undertaking to evaluate user satisfaction, in particular biases linked to social expectations or to the reduction of the subjective process of evaluation through yes/no-type answers to sets of closed questions, we favored in this case methodological strategies that bear the hallmark of ethnography. Through the focal groups technique, the users have been able to express their perception of the program and of the services offered by the teams while they were disclosing their needs and the satisfactions they

    Full Text Available O objetivo da pesquisa, a partir da qual foi elaborado este artigo, consiste em averiguar o suporte informacional da Controladoria para o processo decisório da Logística, com vistas à função de distribuição física dos produtos. Neste sentido, selecionou-se três empresas, a partir de uma relação das empresas de capital aberto do estado de Santa Catarina, obtida junto à homepage da Comissão de Valores Mobiliários - CVM, que possuem uma Controladoria enquanto órgão administrativo e um setor de Logística. Constatou-se que a Controladoria exerce suas funções a fim de contribuir para a otimização dos resultados globais da empresa, contudo não necessariamente gerencia o sistema de informações contábeis-gerenciais nas mesmas. Portanto, conclui-se que os relatórios contábeisgerenciais gerados pela Controladoria com vistas à função da distribuição física de produtos, em geral, não são emitidos de forma específica para o processo decisório da Logística, visto que esta particularidade somente ocorre a partir do momento em que a Controladoria gerencia o sistema de informações.

  15. British Gas plans global gas unit expansion

    International Nuclear Information System (INIS)

    Vielvoye, R.

    1991-01-01

    This paper reports on developing a global gas business, a British Gas plc's strategy for evolving a state owned U.K. gas company to a privatized worldwide oil and gas giant. By 2000, BG's global gas business is expected to provide 20% of its revenues, compared with 40% each from its exploration and production operations and its U.K. gas business. The global gas unit (GGU) plans to meet its targets mainly through acquiring holdings in gas transmission and distribution companies around the world. In the 12 months since GGU was established, it has made two such major acquisitions in this area. BG acquired Consumers Gas Co., Ltd., Ontario, Canada's biggest natural gas distribution company, for $943.5 million. It also took a 10% stake in Catalana de Gas SA, Barcelona, the largest privately owned gas utility in Spain and in terms of number of customers, the fourth largest in western Europe. BG also is targeting additional revenues from developing gas fired cogeneration systems in developing countries with gas reserves but no established transmission and distribution systems

  16. Natural gas production from underground nuclear explosions

    Energy Technology Data Exchange (ETDEWEB)

    1965-01-01

    A remote location in Rio Arriba County, NW. New Mexico, is being considered as the site for an experiment in the use of a nuclear explosive to increase production from a natural gas field. A feasibility study has been conducted by the El Paso Natural Gas Co., the U.S. Atomic Energy commission, and the U.S. Bureau of Mines. As presently conceived, a nuclear explosive would be set in an emplacement hole and detonated. The explosion would create a cylinder or ''chimney'' of collapsed rock, and a network of fractures extending beyond the chimney. The fractures are the key effect. These would consist of new fractures, enlargement of existing ones, and movement along planes where strata overlap. In addition, there are a number of intangible but important benefits that could accrue from the stimulating effect. Among these are the great increase in recoverable reserves and the deliverability of large volumes of gas during the periods of high demand. It is believed that this type of well stimulation may increase the total gas production of these low permeability natural gas fields by about 7 times the amounts now attainable.

    The Rio Claro and Piracununga formations cover extensive areas of the Paulista Peripheral Depression, dominantly in the region of Rio Claro and Piracununga cities. These units lie over the Corumbatai and Piramboia formations, exhibiting discordant contacts. The Rio Claro and Piracununga formations are composed of fine to medium sand facies, showing local cross-stratifications and parallel beddings with thin interbeddings of mud and gravel. These sands were dated by the Thermoluminescence Method, which indicated they were from the Pleistocene age. The oldest age (745,000 years BP) was found in deposits of the Rio Claro Formation; the other ages varied from 400,000 years BP to 145,000 years BP, for both formations. The youngest age (15,000 years BP - close to Pleistocene/ Holocene limit) was found in colluvial deposits, which rest on the Piracununga Formation. (author)

    2013-01-01

    Road transportation has contributed to increased emissions of conventional air pollutants and, consequently, to the increase in problems associated with the environment and human health, depending on the type of pollutant and the concentration of it. To support the development of public policies aimed to decrease total tonnes of emissions, we used a bottom-up approach to estimate the amount of air pollutants, such as carbon monoxide (CO), total hydrocarbons (THC), nitrogen oxides (NO x ), particulate matter (PM), and aldehydes (RCHO), that are emitted by road transportation in the state of Rio de Janeiro (RJ) from 1980 to 2010. The results from 2010 show that cars are responsible for 55% of CO emissions, 61% of THC emissions, and 93% of RCHO emissions. Due to the use of hydrated ethanol and compressed natural gas (CNG) instead of petroleum based fuels during the period analyzed, 1,760,370 t of air pollutant emissions were avoided. Compared to Brazil, in 2010, RJ had a quantity of emissions per vehicle from 12% (CO) to 59% (PM) smaller than the national average. As strategies to reduce air pollutant emissions, we consider reducing the intensity of use, with a proportional reduction in emissions, and increased the use of biodiesel. - Highlights: ► We estimate road transportation emissions for Rio de Janeiro from 1980 to 2010. ► C gasoline was most responsible for CO (74%) and diesel for PM (91%). ► Emissions/vehicle for Rio de Janeiro are (12% to 59%) smaller than Brazilian. ► 1,760,370 t of emissions was avoided using non-petroleum-based fuels. ► Strategies to reduce the emissions of these air pollutants were proposed.

    A high resolution seismic survey was conducted in the Patos Lagoon, southern Brazil, aboard of the research vessel LARUS of the Fundacao Universidade Federal do Rio Grande (FURG). Around 400 km of 3.5 k Hz seismic profiles were collected, which provided acoustic signals of good penetration depth and resolution. Seismic anomalies, including turbidity and pocket gas, revealed that gas-charged sediments are common in several areas of the lagoon. The gas accumulations in the Patos Lagoon are controlled by the spatial distribution of the sedimentary facies. Either in 'curtains' or in 'acoustic turbid zones', the main gas accumulations occur in areas with paleotopographic lows related to fluvial channels and valleys developed in the Rio Grande do Sul coastal plain during regressive/transgressive events of the Quaternary.

    We present the discovery and spectroscopic confirmation with the European Southern Observatory New Technology Telescope (NTT) and Gemini South telescopes of eight new, and the rediscovery of two previously known, 6.0 VISTA Hemisphere Survey (J, H, K) and Wide-field Infrared Survey Explorer (W1, W2). The photometric data were fitted with a grid of quasar model SEDs with redshift-dependent Ly α forest absorption and a range of intrinsic reddening as well as a series of low-mass cool star models. Candidates were ranked using an SED-model-based χ2-statistic, which is extendable to other future imaging surveys (e.g. LSST and Euclid). Our spectral confirmation success rate is 100 per cent without the need for follow-up photometric observations as used in other studies of this type. Combined with automatic removal of the main types of non-astrophysical contaminants, the method allows large data sets to be processed without human intervention and without being overrun by spurious false candidates. We also present a robust parametric redshift estimator that gives comparable accuracy to Mg II and CO-based redshift estimators. We find two z ˜ 6.2 quasars with H II near zone sizes ≤3 proper Mpc that could indicate that these quasars may be young with ages ≲ 106-107 years or lie in over dense regions of the IGM. The z = 6.5 quasar VDES J0224-4711 has JAB = 19.75 and is the second most luminous quasar known with z ≥ 6.5.

    We present the discovery and spectroscopic confirmation with the ESO NTT and Gemini South telescopes of eight new 6.0 < z < 6.5 quasars with z$_{AB}$ < 21.0. These quasars were photometrically selected without any star-galaxy morphological criteria from 1533 deg$^{2}$ using SED model fitting to photometric data from the Dark Energy Survey (g, r, i, z, Y), the VISTA Hemisphere Survey (J, H, K) and the Wide-Field Infrared Survey Explorer (W1, W2). The photometric data was fitted with a grid of quasar model SEDs with redshift dependent Lyman-{\\alpha} forest absorption and a range of intrinsic reddening as well as a series of low mass cool star models. Candidates were ranked using on a SED-model based $\\chi^{2}$-statistic, which is extendable to other future imaging surveys (e.g. LSST, Euclid). Our spectral confirmation success rate is 100% without the need for follow-up photometric observations as used in other studies of this type. Combined with automatic removal of the main types of non-astrophysical contaminants the method allows large data sets to be processed without human intervention and without being over run by spurious false candidates. We also present a robust parametric redshift estimating technique that gives comparable accuracy to MgII and CO based redshift estimators. We find two z $\\sim$ 6.2 quasars with HII near zone sizes < 3 proper Mpc which could indicate that these quasars may be young with ages < 10$^6$ - 10$^7$ years or lie in over dense regions of the IGM. The z = 6.5 quasar VDESJ0224-4711 has J$_{AB}$ = 19.75 is the second most luminous quasar known with z > 6.5.

    Here, we present the discovery and spectroscopic confirmation with the European Southern Observatory New Technology Telescope (NTT) and Gemini South telescopes of eight new, and the rediscovery of two previously known, 6.0 < z < 6.5 quasars with zAB < 21.0. These quasars were photometrically selected without any morphological criteria from 1533 deg2 using spectral energy distribution (SED) model fitting to photometric data from Dark Energy Survey (g, r, i, z, Y), VISTA Hemisphere Survey (J, H, K) and Wide-field Infrared Survey Explorer (W1, W2). The photometric data were fitted with a grid of quasar model SEDs with redshift-dependent Ly α forest absorption and a range of intrinsic reddening as well as a series of low-mass cool star models. Candidates were ranked using an SED-model-based χ2-statistic, which is extendable to other future imaging surveys (e.g. LSST and Euclid). Our spectral confirmation success rate is 100 per cent without the need for follow-up photometric observations as used in other studies of this type. Combined with automatic removal of the main types of non-astrophysical contaminants, the method allows large data sets to be processed without human intervention and without being overrun by spurious false candidates. We also present a robust parametric redshift estimator that gives comparable accuracy to Mg ii and CO-based redshift estimators. We find two z ~6.2 quasars with H ii near zone sizes ≤3 proper Mpc that could indicate that these quasars may be young with ages ≲ 10 6 -10 7 years or lie in over dense regions of the IGM. The z = 6.5 quasar VDES J0224–4711 has JAB = 19.75 and is the second most luminous quasar known with z ≥ 6.5.

    Full Text Available Geração após geração, ouvimos um discurso de educação de qualidade conforme previsão legal. No entanto, há impasses do processo ensino-aprendizagem, a começar pelo distanciamento do discurso à realidade escolar onde temos o professor e o gestor que, em regra, vivenciam práticas culturais escolares baseadas na perspectiva analógica do século XX. Por sua vez, a estrutura escolar advém de uma lógica de vigilância e disciplina do século XIX. Pari passo as dimensões culturais intergeracionais e seus conflitos identifica-se um aluno da era digital focado na ética e estética do consumo. Assim, advém a necessidade de rupturas quanto ao olhar etnocêntrico dos diversos sujeitos sociais pelo aprendizado compartilhado (professores, alunos, gestores, comunidade. Há, portanto, a necessidade da escola se abrir ao diálogo respeitoso e sem preconceitos, com vistas ao desenvolvimento humano. A educação no século XXI orienta-se na concepção inclusiva, da diversidade e pluralismo cultural. A escola democrática se faz pela práxis que vislumbre uma aprendizagem significativa e permita o desenvolvimento humano. Nesse diapasão, encontramos inserido o Novo Plano Nacional de Educação como instrumento discursivo que vislumbra uma educação de qualidade.

    Full Text Available The enormous development that computer and communication technologies have experienced during last decades has caused several ethical problems and theoretical debates. However, a gender perspective has not been traditionally included in these researches. Some of the first feminist analyses about digital technologies have emerged within STS, being much scarce in the discipline of Computer Ethics. In this paper I will briefly expose some of these analysis, and will argue for the importance of the gender perspective for an appropriate understanding of this phenomenon, both regarding technology and society relation and in relation to the ethical problems which are the concern of Computer Ethics.

    Every two years, the International Energy Agency (IEA) publishes the 'Energy Technology Perspectives' (ETP) report which analyses the foreseeable energy scenarios and strategies at the 2050 vista and stresses on the best available technologies. For the first time, the IEA describes in this study a scenario allowing to divide by two the CO{sub 2} emissions at the world scale, i.e. compatible with the 'factor 4' scenario of industrialized countries. The study estimates the R and D needs and the necessary additional investments to meet the different tendentious and voluntaristic scenarios proposed by the IEA. This 15. session of the cycle of energy-climate conferences aimed at presenting, from the ETP 2008 study, a thorough examination of the present day situation and perspectives of existing or future 'clean' energy technologies through the analysis of several scenarios. An examination of the interpretation of these scenarios at the France and European levels is made in order to define what should be the trends of public policies and international cooperation. This document gathers the transparencies of the two presentations given during this conference. The first presentation by Pieter Boot, Director of the Office of Sustainable Energy Policy and Technology of IEA, makes a synthesis of the ETP study and presents the recommendations of the agency. The second presentation by Olivier Appert, President of the French institute of petroleum (IFP), gives a counterpoint of the first presentation by considering the financing and acceptance aspects, in particular from the French point of view. Finally a debate with the audience completes the presentations. (J.S.)

    Full Text Available Este artigo teve como objetivo analisar o itinerário dos usuários que tiveram acesso a medicamentos via judicial no estado do Amazonas, Brasil. Trata-se de estudo qualitativo, prospectivo, baseado em dados coletados por meio de entrevistas semiestruturadas com usuários que receberam medicamentos via mandado judicial. A judicialização na saúde mostrou-se um fator agregador ao reconhecimento dos direitos e da cidadania pelos usuários que, na sua trajetória de vida, acabaram adquirindo um grande aprendizado sobre formas de enfrentar a falta de acesso aos medicamentos. Conclui-se que a relação entre o sujeito e o Estado permanece desigual, e o direito à saúde se deu na dimensão individual e restritiva, desconsiderando a dimensão coletiva e a concepção de cidadania.

Busca a proposição de um conjunto de métodos e técnicas de APO com abordagem funcional, destinado a edifícios de apartamentos e elaborado a partir de parâmetros homogêneos de maneira a constituir um método reaplicável. O conjunto de métodos e técnicas utilizados nesta pesquisa busca compreender a relação entre o comportamento do usuário e o projeto idealizado pelos vários agentes do mercado imobiliário. Para tal utilizou-se múltiplos métodos de natureza quantitativa e qualitativa, com destaque para a utilização de Grupos Focais e a incorporação da opinião do pesquisador nas avaliações. A pesquisa parte da análise da produção de edifícios de apartamentos a partir do ano de 2000. Seleciona a produção destinada à classe média na cidade de São Paulo, que por seu porte constitui-se como um modelo de referência para o mercado imobiliário nas demais regiões do país. Dessa forma, conforme explicitado no corpo do artigo, escolheu-se a cidade de Ribeirão Preto para o desenvolvimento e aplicação da APO em três estudos de caso. Os resultados obtidos na aplicação da APO nos estudos de caso ribeirão-pretanos atestam o atendimento das demandas dos moradores de maneira mínima, na medida em que identificou-se uma gama bastante variada de grupos familiares morando em modelos repetidos e tripartidos de habitar. Várias sobreposições de atividades foram identificadas nos cômodos dos edifícios estudados, que são projetados de maneira tradicional, baseados na sua estanqueidade, compartimentação e monofuncionalidade. Conclusivamente indica-se para a produção destes empreendimentos, a necessidade de uma conexão maior e mais efetiva entre pesquisa e prática a partir da criação de bancos de dados municiados por APOs.

  13. Retrofitting Housing with Lightweight Green Roof Technology in Sydney, Australia, and Rio de Janeiro, Brazil

    Full Text Available The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof retrofitting. The environmental benefits include reduced operational carbon emissions, reduced urban heat island effect, increased bio-diversity, housing temperature attenuation and reduced stormwater run-off. The economic benefits are the reduced maintenance costs and lower running costs. The social gain is the creation of spaces where people have access to green areas. However, the barriers to retrofitting include the perceptions of structural adequacy, the risk of water damage, high installation and maintenance costs, as well as access and security issues. Many Australian and Brazilian residential buildings have metal sheet roofs, a lightweight material with poor thermal performance. During the summer, temperatures in Sydney and Rio de Janeiro reach 45 degrees Celsius, and in both cities, rainfall patterns are changing, with more intense downpours. Furthermore, many residential buildings are leased, and currently, tenants are restricted by the modifications that they can perform to reduce running costs and carbon emissions. This research reports on an experiment on two small-scale metal roofs in Sydney and Rio de Janeiro to assess the thermal performance of portable small-scale modules. The findings are that considerable variation in temperature was found in both countries, indicating that green roof retrofitting could lower the cooling energy demand considerably.

    1978-09-01

    The designer of a nuclear plant must know the plant's associated risk limitations so that he can design the plant accordingly. To design a safety system, he must understand its importance and how it relates to the overall plant risk. The computer program RIO can aid the designer to understand a system's contribution to the plant's overall risk. The methodology developed and presented was sponsored by the Nuclear Research Applications Division of the Department of Energy for use in the Gas Cooled Fast Breeder Reactor (GCFR) Program. The principal motivation behind its development was the need to translate nuclear plants safety goals into reliability goals for systems which make up that plant. The method described herein will make use of the GCFR Accident Initiation and Progression Analyses (AIPA) event trees and other models in order to determine these reliability goals

    The function of the infrared gas transducer used during extravehicular activity in the current space suit is to measure and report the concentration of carbon dioxide (CO2) in the ventilation loop. The next generation portable life support system (PLSS) requires next generation CO2 sensing technology with performance beyond that presently in use on the Space Shuttle/International Space Station extravehicular mobility unit (EMU). Accommodation within space suits demands that optical sensors meet stringent size, weight, and power requirements. A laser diode spectrometer based on wavelength modulation spectroscopy is being developed for this purpose by Vista Photonics, Inc. Two prototype devices were delivered to NASA Johnson Space Center (JSC) in September 2011. The sensors incorporate a laser diode-based CO2 channel that also includes an incidental water vapor (humidity) measurement and a separate oxygen channel using a vertical cavity surface emitting laser. Both prototypes are controlled digitally with a field-programmable gate array/microcontroller architecture. The present development extends and upgrades the earlier hardware to the Advanced PLSS 2.0 test article being constructed and tested at JSC. Various improvements to the electronics and gas sampling are being advanced by this project. The combination of low power electronics with the performance of a long wavelength laser spectrometer enables multi-gas sensors with significantly increased performance over that presently offered in the EMU.

    The coal mines in Brazil are primarily located in southern part areas. The total coal reserves are approximately 32.8 billions tons, 89% of which are located in Rio Grande do Sul state. The Brazilian agriculture potentiality is very high, mainly due to the availability of flat land and the existence of industrial capacity to supply the main fertilizers needs. Electron beam flue gas treatment process ensures simultaneous removal of SO 2 and NO X from flue gases by single process, requiring no additional wastewater treatment system and can produce useful nitrogen fertilizer consisting of ammonium sulfate (NH 4 ) 2 SO 4 and ammonium nitrate NH 4 NO 3 as by-products. During the TC Project BRA/8/021 - Pilot Plant for Electron Beam Purification of Flue Gas supported by IAEA (1995-1996), a laboratory facility for electron beam flue gas treatment was set at IPEN. In 1997, an official request from Brazilian Government, Ministry of Science & Technology (MCT) and IPEN was made for the Japan Consulting Institute (JCI) to prepare feasibility studies of air pollution control by electron beam flue gas treatment in three power generation companies. These companies are responsible for the power generation, the transmission and the supply of electricity to Brazil: Jorge Lacerda – Eletrosul Centrais Eletricas do Sul do Brasil S.A., Presidente Medici – Companhia Estadual de Energia Eletrica (CEEE) and Piratininga – AES Eletropaulo Thermal Power Plants.
