  1. Assessment of metal concentrations in sediment samples from Billings reservoir, Rio Grande tributary, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The present study chemically characterized sediment samples from the Billings reservoir, Rio Grande tributary, in the Metropolitan region of Sao Paulo, by determining metal concentration and other elements of interest. The chosen chemical parameters for this characterization were Aluminum, Arsenic, Barium, Cadmium, Copper, Chromium, Iron, Lead, Manganese, Mercury, Nickel, Selenium and Zinc. These parameters are also used in the water quality index, with the exception of Selenium. The concentrations were determined through different analytical techniques such as atomic absorption spectrometry (FAAS, GFAAS and CVAAS), optical emission spectrometry (ICP OES) and neutron activation analysis. These analytical methodologies were assessed for precision, accuracy and detection and/or quantification limits for the sediment elements in question. Advantages and disadvantages of each technique for each element and its concentration were also discussed. From these assessment the most adequate technique was selected for the routine analysis of sediment samples for each element concentration determination. This assessment verified also that digestion in a closed microwave system with nitric acid is efficient for the evaluation of extracted metals of environmental interest. The analytical techniques chosen were equally efficient for metals determination. In the case of Cd and Pb, the FAAS technique was selected due to better results than ICP OES, as it does not present matrix interference. The concentration values obtained for metals As, Cd, Cu, Cr, Hg, Ni, Pb and Zn in the sediment samples were compared to Canadian Council of Minister of the Environment (CCME) TEL and PEL values.

    Full Text Available Este trabalho teve como objetivo avaliar em escalas espacial (vertical e horizontal e temporal as características limnológicas do Reservatório Rio das Pedras (Complexo Billings, São Bernardo do Campo, SP – Brasil. Nos meses de março e outubro de 2004 foram amostradas em perfil três estações no reservatório. As variáveis analisadas foram: temperatura, condutividade elétrica e pH, com sonda multiparâmetros; concentrações de amônio, nitrito, nitrato, fosfato, ortosilicato, fósforo total, clorofila-a e feofitina, por método espectrofotométrico; oxigênio dissolvido por método titulométrico; além das concentrações de sólidos totais e material em suspensão. Para análise estatística dos dados foi aplicada a ACP (Análise de Componentes Principais. A heterogeneidade temporal observada foi conseqüência das diferenças de temperatura, que geraram estratificação térmica, química e biológica, no mês de março. As diferenças espaciais verticais também resultaram da estratificação térmica. As maiores discrepâncias das características limnológicas, em relação ao padrão de distribuição espacial horizontal, foram obtidas na estação 1, e são diretamente relacionadas à influência das águas provenientes do reservatório Billings. De acordo com a CONAMA 357/05, para o mês de outubro de 2004 as águas do reservatório estão em conformidade com a Classe 3. Para o mês de março, na estação 3 os valores estão abaixo do estabelecido, conferindo não conformidade para a Classe 3.

  5. Assessment of major and trace elements in sediment samples from Billings Dam, Rio Grande reservoir, by neutron activation analysis

    International Nuclear Information System (INIS)

    The Rio Grande Reservoir, Southeast of the Sao Paulo Metropolitan Area (SPMA), supplies water for four counties (Sao Bernardo do Campo, Sao Caetano do Sul, Santo Andre and Diadema). It has been seriously affected by urban expansion, due to chaotic urban occupation and improper use of the surrounding areas. In this study cores and bottom sediment samples were collected, by using a piston corer and Van Veen samplers, respectively, during the dry season (May to August, 2004). The Van Veen sampler collected 3 samples of 50 cm from each other in a triangle around the point where the piston corer sample was collected. These 3 samples constituted a composed sample. Each of the four piston corer samples were sliced resulting in 4 samples each: 0-5, 5-10, 10-20 and 20-30 cm deep. Four sampling points were defined by using a GPS and are located at the mouth of Rio Grande and Ribeirao Pires Rivers (discharge of contaminants - point 4), in the middle of the reservoir (points of depuration - point 3 and 2) and near the catchment point of the water supply (point 1). The sediment samples were submitted to instrumental neutron activation analysis and the following elements were determined: As, Ba, Br, Co, Cr, Cs, Fe, Na, Rb, Sb, Sc, Se, Ta, Th, U e Zn and the rare earth elements Ce, Eu, La, Lu, Nd, Sm, Tb, Yb. The methodology validation was carried out by certified reference material analyzes. As for the results obtained for these elements in the core samples, there was a significant variation concentration in the four sampling points, mainly for As and Cr at point 1. When we compared these values with ISQL and PEL from Environmental Canada (Canadian Sediment Quality Guidelines) we observed that As and Cr levels are above PEL and TEL values, indicating a strong anthropogenic contribution. For the other sampling points high concentration values were observed for the majority of the elements analyzed as well. (author)

    Full Text Available The objective of the present study was to evaluate spatial and temporal patterns of limnological characteristics of the Rio das Pedras Reservoir (Billings Complex, São Bernardo do Campo, São Paulo – Brazil. Profile samples were taken at three stations during two periods (March and October, 2004. The variables analyzed were: temperature, electrical conductivity, pH, with multiparameter probe; concentration of ammonium, nitrite, nitrate, phosphate, orthosilicate, total phosphorus, chlorophyll-a and phaeophytin, by spectrophotometric method; dissolved oxygen by titrimetric method; beyond concentrations of total solids and suspended material. PCA (Principal Components Analyses was applied for the statistical analyses. The temporal heterogeneity observed was a consequence of differences in temperature observed in the month of March, which generated thermal, chemical and biological stratification. The vertical spatial differences also resulted from the thermal stratification. The largest discrepancies in the limnological characteristics, in relation to the pattern of horizontal spatial distribution, were obtained in station 1, and are directly related to the influence of the incoming waters of the Billings reservoir. According to CONAMA 357/05, for the month of October, 2004, the waters of the reservoir were in accordance with Class 3. In March, the values for station 3 were below the standards established, indicating non-conformity with Class 3.

  9. Project Rio Blanco: additional production testing and reservoir analysis

    International Nuclear Information System (INIS)

    Additional subsurface investigations of the Rio Blanco detonation region and adjacent reservoir have been underway since the last technical meeting at IAEA. The lowermost explosion cavity has been reentered and a production test from it was performed. A dry gas volume of 7.6 x 105 m3 (27 Mmscf) was withdrawn. Chemical and radiochemical analyses of this gas show that (1) the yield of the bottom explosive was 31 +- 2 kt; (2) the cavity/chimney volume was 2.4 x 104 m3 (8.4 x 105 ft3); (3) about 7 percent of the tritium produced is associated with the gas; and (4) a slight (approximately 0.1 percent) gas contribution from the middle explosion region was noted. The reservoir/chimney model implies an unstimulated reservoir flow capacity of 0.15 mdarcy-m (0.50 md-ft) connected to the bottom chimney region. A cavity radius of 21 +- 3 m (70 +- 10 ft) was deduced. Unstimulated reservoir production parameters were investigated in a well offset 190 m (625 ft) from the emplacement hole. Insufficient productivity was obtained in the Mesaverde formation (in which the bottom explosive was detonated) to evaluate reservoir properties. The productive sandstones in the Fort Union formation adjoining the top detonation region were individually evaluated. Their aggregate flow capacity was determined to be 0.14 +- 0.2 mdarcy-m (0.45 +- 0.08 md-ft). A numerical simulation model which incorporates these data is described. The lack of a high-permeability connection between the three explosion regions remains unexplained. The two chimney reentry wells have been cemented to the surface and abandoned. The offset well has been plugged in a way which preserves the option for additional subsurface investigation in the future. Project facilities have been removed and the site restored to conditions which minimize environmental impact

    Full Text Available The large population contingent and the precarious urban planning in the metropolitan region of São Paulo have resulted in uncontrolled growth in areas where springs exist, generating strong pressures on the reservoirs. Concomitantly, a lack of articulation between public and private policy has led to various socio-environmental conflicts in the Billings watershed. This spring, which is responsible for the direct and indirect supply of water to millions of people, represents an enormous challenge for water resource management. In this context, this study aimed to analyze the seasonal limnological conditions of the Billings Complex, in particular the Rio Grande and Taquacetuba branches, and discuss the implications for the management procedure applied in the branches. Physical (water temperature, pH, electrical conductivity, suspended material, organic and inorganic suspended material chemical (dissolved oxygen, total phosphorus and nitrogen, nitrate, nitrite, ammonium and inorganic phosphorus and biological (chlorophyll-a variables of the water were analyzed and the Trophic State Index was calculated. The results indicate a hypertrophic state in the Taquacetuba branch. The Rio Grande branch presented a mesotrophic state which is, however, artificially maintained due to copper sulfate and hydrogen peroxide treatments. The results are also discussed in light of CONAMA Resolution 357/2005. Levels of chlorophyll-a and total phosphorous in the Taquacetuba branch do not conform to the proposed class of use, class I. In this branch, monitoring must be intensified and measures adopted to reduce the level of nutrients in the main body of the Billings complex.

    The primary assertion is that this article argues that the recovery in production of hydropower in Henry Borden (UHB) is the reduction of environmental liabilities in the Billings reservoir. In this context, the aim of this paper is to provide a first consideration of the possibility of recovery of production Henry Borden hydropower plant of recovering the multiple uses of the reservoir. From this perspective, we interviewed representatives of CETESB (Sanitation Environmental Technology Company) and EMAE (Metropolitan Water and Energy Company SA) for consideration of actions that include environmental policies aimed at increasing the production of electricity in Henry Borden in order to obtain results that may contribute to the multiple uses of the Billings reservoir. Noting that the range of laws aimed at protecting the water sources was limited to disjointed public policy that has reduced the resilience of the Billings reservoir. (author)

    Sedimentation of Rio La Venta as it enters the Netzahualcoyotl Reservoir in Chiapas, Mexico, threatens a unique part of the aquatic ecosystem. Rio La Venta enters the reservoir via a narrow canyon about 16 km long with spectacular, near-vertical limestone bluffs up to 320 m high and inhabited by the flora and fauna of a pristine tropical forest. Karst terrain underlies most of the Rio La Venta basin in the vicinity of the reservoir, while deeply weathered granitic terrain underlies the Rio Negro basin, and the headwaters of the Rio La Venta to the south. The Rio Negro joins Rio La Venta 3 km downstream of the upper limit of the reservoir and delivers the bulk of the total clastic sediment (mostly sand and finer material). The canyon and much of the contributing basin lie within the Reserva de la Biosfera, Selva El Ocote, administered by the Comision Nacional de Areas Naturales Protegidas, part of the Secretaria de Medioambiente y Recursos Naturales. The Klamath National Forest Forest has cooperated with its Mexican counterparts since 1993 in natural resource management, neo-tropical bird inventories, wildfire management, and more recently in watershed analyses. Rates of sedimentation are estimated from bathymetric surveys conducted in March, 2002. A longitudinal profile down the inundated canyon during a high reservoir level shows an inflection from a slope of 0.0017 to one of 0.0075 at 7.2 km downstream of the mouth of Rio Negro. The bed elevation at this point corresponds to the lowest reservoir level, suggesting that the gentler sloping bed upstream is formed by fluvial processes during drawdown and that downstream by pluvial processes. Using accounts that boats could access Rio Negro during low water levels in 1984, we estimate an annual sedimentation rate of roughly 3 million cubic meters per year. This suggests that boats might no longer be able to access the most spectacular section of canyon upstream of Rio Negro within a decade, depending on how the

  15. Major and trace elements assessment in sediment samples from Rio Grande Reservoir, by neutron activation analysis

    International Nuclear Information System (INIS)

    The Rio Grande Reservoir, Southeast of the Sao Paulo Metropolitan Area (SPMA) supplies water for four counties (Sao Bernardo do Campo, Sao Caetano do Sul, Santo Andre and Diadema). It has been seriously affected by urban expansion, due to chaotic urban occupation and improper use of the surrounding areas. In this study bottom sediment samples were collected, by using a Van Veen sampler, during the dry and rainy seasons. Four sampling points were defined by using GPS and are located at the mouth of the Rio Grande and Ribeirao Pires Rivers, in the middle of the reservoir and near the catchment point of the water supply. The sediment samples were submitted to instrumental neutron activation analysis (INAA) and the following elements were determined: As, Ba, Br, Co, Cr, Cs, Rb, Sb, Sc, Se, Ta, Th, U e Zn and the rare earth elements Ce, Eu, La, Lu, Nd, Sm, Tb, Yb. Short irradiation was also performed for total Hg determination by NAA using 197Hg radioisotope. This was possible due to the high Hg concentration levels in these sediments. The methodology validation was carried out by certified reference material analyses. The results obtained for multielemental concentrations in the sediment samples were compared to NASC (North American Shale Composite) values. The concentration values obtained for As and metals Cr, Hg and Zn in the sediment samples were compared to the Canadian Council of Minister of the Environment (CCME) oriented values (TEL and PEL values) and adopted by CETESB.

    The Rio Grande reservoir is located in the Metropolitan area of Sao Paulo and it is used for recreation purposes and as source water for drinking water production. During the last decades has been detected mercury contamination in the sediments of this reservoir, mainly in the eastern part, near the main affluent of the reservoir, in the Rio Grande da Serra and Ribeirao Pires counties. In the present study bottom sediment samples were collected in four different sites into four sampling campaigns during the period of September 2008 to January 2010. The samples were dried at room temperature, ground and passed through a 2 mm sieve. Total Hg determination in the sediment samples was carried out by two different analytical techniques: neutron activation analysis (NAA) and cold vapor atomic absorption spectrometry (CV AAS). The methodology validation, in terms of precision and accuracy, was performed by reference materials, and presented a recovery of 83 to 108%. The total Hg results obtained by both analytical techniques ranged from 3 to 71 mg kg-1 and were considered similar by statistical analysis, even though NAA technique furnishes the total concentration while CV AAS using the 3015 digestion procedure characterizes only the bioavailable Hg. These results confirm that both analytical techniques were suitable to detect the Hg concentration levels in the Rio Grande sediments studied. The Hg levels in the sediment of the Rio Grande reservoir confirm the anthropogenic origin for this element in this ecosystem. (author)

    A joint sedimentation study is currently underway at the Netzahualcoyotl reservoir in Chiapas, Mexico, involving the Comision Nacional de Areas Naturales Protegidas (CONANP) of the Secretaria de Medio Ambiente y Recursos Naturales and the USDA Forest Service. The reservoir is adjacent to the Reserva de la Biosfera, Selva El Ocote, administered by CONANP. Ongoing research is intended to provide watershed and reservoir managers with strategies to protect the resources of Rio La Venta canyon. The Rio La Venta arm of the reservoir is incised into karst terrain, with near-vertical limestone walls up to 300 meters high. The canyon is fed by two rivers, Rio La Selva and Rio Negro, and is surrounded by pristine tropical forest. The majority of the clastic sediment (predominantly sand and fine gravel) entering the reservoir originates in the headwaters of the two rivers which are underlain by weathered and dissected granitic terrain. Rapid sedimentation of the partially inundated canyon poses a threat to the aquatic ecosystem, as well as to recreational resources. Longitudinal and transverse profiles were surveyed in the inundated canyon in March of 2002 and repeated in April of 2003 when the reservoir level was 15 meters lower. The 2002 longitudinal profile shows an inflection from a slope of 0.0017 to one of 0.0075 at 7.2 km downstream of the mouth of Rio Negro. In 2003, the two slopes remained the same, but the bed lowered about 5 meters and the inflection point moved downstream about 2.3 km. We calculated that reservoir lowering in 2003 allowed the transport of 2.5 million cubic meters of sand further out into the reservoir. This volume is more than the average annual rate of filling up to the 2002 level since 1984 when sedimentation was not as advanced (De la Fuente et al., 2002), which was calculated disregarding loss of sediment to the main reservoir. Field observations at late dry season low flows in 2003 revealed active transport of sand and pebbles and formation

    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.

    Full Text Available Mudanças na temperatura da água e na dinâmica de estratificação térmica podem causar efeitos negativos sobre os processos físicos, químicos e biológicos de reservatórios. A variação da temperatura afeta a densidade da água e, como consequência, altera os processos de transporte. Um modelo unidimensional de transferência de calor é utilizado para simular a temperatura do reservatório do Rio Verde, localizado na região metropolitana de Curitiba, Estado do Paraná. Na solução da equação, usou-se o método de diferenças finitas. O modelo foi calibrado e validado por meio dos dados de dois meses: julho de 2009 e março de 2010. Os resultados mostram uma boa concordância entre os valores simulados e observados. Esses resultados ainda permitem avaliar as relações da profundidade da termoclina com a radiação solar e a velocidade do vento.Changes in the water temperature and in the thermal stratification dynamics can be responsible for negative effects on physical, chemical and biological processes of reservoirs. The temperature variation affects the water density and, consequently, alters the transport processes. A one-dimensional model of thermal evolution is used to simulate the temperature of Rio Verde reservoir, located in the Curitiba metropolitan area, Paraná state, Brazil. The finite difference method was employed for the numerical solution of the equation. The model was calibrated and validated by means of the data from two different months: July 2009 and March 2010. The results show a good agreement between simulated and observed values. These results still allow evaluating the relationships between the depth of the thermocline with solar radiation and wind speed.

  5. Trace metal and rare earth elements in a sediment profile from the Rio Grande Reservoir, Sao Paulo, Brazil: determination of anthropogenic contamination, dating, and sedimentation rates

    International Nuclear Information System (INIS)

    The Rio Grande Reservoir supplies water to four counties. Two sediment cores were collected, one was sliced every 2 cm for INAA and dating determinations; the other was cut every 5 cm, for grain size and Hg, Cd, Pb, Ni, Mn and Cu determinations. Sedimentation rates and sediment ages of every layer were determined by 210Pb method. Enrichment Factor (EF) and Geoaccumulation Index (Igeo) were calculated. Significant enrichment was found for Na, Mn, Ni, Pb, Sb and Zn and extremely high enrichment for Hg, Cu and Cd, in upper layers. A 90 year pollution history of this reservoir was traced. (author)

Foram analisadas três subbacias de açudes - Araras, Edson Queiroz e Jaibaras, da bacia do Acaraú, CE, Brasil. A análise multiatributo usada na definição de indicadores ambientais de vulnerabilidade dos açudes à eutrofização, considerou sua sensibilidade e fatores de pressão nas suas sub-bacias que acarretam o transporte de sedimentos e nutrientes para os reservatórios. Foi utilizado um Sistema de Informações Geográficas (SIG com a ferramenta álgebra de mapas para manipular dados de uso e ocupação do solo, declividade do terreno e erodibilidade do solo. Foi identificada alta vulnerabilidade à eutrofização nos três açudes pelas susceptibilidades à erosão, alta carga poluidora principalmente pela pecuária extensiva na região e baixa profundidade relativa dos reservatórios.This work presents a tool to analyze the vulnerability of reservoirs to eutrophication, aiming to subsidize control and remediation actions related with this process. It was analyzed the water basins of Araras, Edson Queiroz and Jaibaras reservoirs, located in the Acaraú watershed, Ceará, Brazil. The multi-criteria analyses methodology used, in order to define environmental vulnerability indicators to reservoir eutrophication, considered reservoir sensibility and pressure factors in the water basin responsible for the transport of sediments and nutrients to the reservoir. A Geographic Information System (GIS with map algebra as major tool was applied to soil use and occupation, declivity and erosion indicators. It was identified high vulnerability to eutrophication in the three mentioned reservoirs because of the waterbasins susceptibility to erosion, high phosphorous load mainly from the extensive cattle raising and low relative depth of the reservoirs.

However, there is a lack of knowledge on their fish fauna in many areas, including headwaters. The present study aimed to describe the fish community structure from Juramento reservoir, located on Juramento River, a branch of SFR basin. Six bimonthly samplings were made in four different sites. Gill and cast nets, beach seines and sieves were used to collect fish. Ecological indexes as well as the relationship between fish abundance and some limnological variables were determined. 3288 fish belonging to 33 species (16.5% of the total described for SFR basin were captured, being 75.7% Characiformes, 18.1% Siluriformes, 3% Cyprinodontiformes and 3% Gymnotiformes. Only two non-native species, 'tamboatá' - Hoplosternum littorale (Hancock, 1828 and 'trairão' - Hoplias lacerdae Ribeiro, 1908 were found. The highest catches in number occurred in the dry period (March-October and the lowest one in the wet season (November-February. Diversity was higher at Barragem station and richness did not vary between reservoir zones. Five migratory species were found downstream of the dam (four exclusively there, whereas only the 'curimbatá-pioa' - Prochilodus costatus Valenciennes, 1850 occurred in the reservoir. The low observed correlations between fish abundance and the limnological variables utilized suggest that the local fish fauna is not strongly affected by their variation.No Brasil, vários rios, como os da bacia do São Francisco (RSF, são barrados para a formação de reservatórios.

  14. Determination of total and organic mercury and evaluation of methylation and demethylation processes in sediments of the Rio Grande Reservoir, State of Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The Rio Grande reservoir is located in the metropolitan area of Sao Paulo and it is a very important water supply for this region. In the present study bottom waters and sediment samples collected in this reservoir, in four sampling points, in four campaigns, from September 2008 to January 2010, were analyzed. Firstly total Hg was determined in sediment and bottom waters by cold vapor atomic absorption technique (CV AAS). Following, the analytical methodology for organic Hg was adapted from literature, where the organomercurial compounds were extracted with dichloromethane in acid medium and subsequent destruction of organic compounds by bromine chloride. The validation of this methodology, in terms of precision and accuracy, was performed by means of IAEA 405 and BCR-CRM 580 reference materials analyses. For methylation and demethylation processes evaluation in this environment, the following physical and chemical parameters were assessed, in situ: pH, water temperature, redox potential (EH), transparency and depth. For the sediment samples, granulometry, total organic carbon, sulphate-reducing bacteria, total N and P, besides the metals Co, Cu, Fe and Mn were evaluated. The selection of these parameters was related to the factors that influence the behavior of MeHg in the sediments and its transition zone. Total Hg ranging from 1.0 to 71.0 mg kg'-1 and organic mercury from -1 in sediments and methylation rates from 0.06 to 1.4% were found, along the reservoir. Different methylation conditions along the reservoir and its influences were also discussed. As supplementary study the concentration of some metals and trace elements in the sediments by neutron activation analysis technique was determined. As, Ba, Br, Co, Cr, Cs, Hf, Fe, Na, Rb, Sb, Sc and Zn and rare earth elements Ce, Eu, La, Lu, Nd, Sm and Yb were determined. The enrichment factor in relation to earth crust values using Sc as normalizer element reached values higher than 2.0 for the elements As, Br, Sb

    The objective of this study is to develop an integrated hydrologic-agronomic-economic annual model for the optimal operation of the Yaqui River reservoir system to support irrigation and urban water supply in the watershed. The model solves for each year's water allocations by crop, maximizing annual agricultural income for a specified risk of reservoir shortages and spills. It accounts for adjustments in water supply arising from changes in precipitation and runoff uncertainty and from changes in water demand arising from variations in crop prices and production costs. Model predictions for the agricultural year 2000-2001 are compared with observed results to test the model's predictive ability. Results demonstrate that the model can be used to optimize and analyze reservoir system operation and for water resources management in the Irrigation District No. 041, providing a framework for improving the operation of a reservoir system, selecting an optimal cropping pattern according to its maximum economic benefits, and in the optimal monthly water releases from the reservoir system. The model considers the simultaneous operation of three dams and it is applied to the Irrigation District No. 041, Rio Yaqui.

Several other vertebrate species including man may become infected by ingestion of the third stage larvae produced by the intermediate hosts, usually slugs from the family Veronicellidae. There is a report of the diagnosis of abdominal angiostrongyliasis in Canis familiaris with lesions resembling those found in human disease. As a preliminar evaluation of the adequacy of a canine model for pathogenetic studies, a dog was inoculated with 75 L3 of A. costaricensis. Infection was established and fist stage larvae were found in feces up to 88 days post infection, sometimes in very large numbers (9.5 x 10(4 L1/g. No clinical manifestations or significant lesions were detected.

    Understand main factors that controls the crustal permeability related to giant ore deposits is a crucial goal for improving metallogenic models. Subsurface data at distrital scales, remains a key factor to reach that goal, however use of regional geophysical methodologies are still extremely expensive and poorly developed on ore exploration. We present the results associated to distrital structural analyses, combined with passive seismic tomography in a case study in Central Andes. Tectono-magmatic evolution of the Rio Blanco-Los Bronces District (Porphyry Cu-Mo Deposit) involves a complex interaction of different processes along the time which includes: Pre-Mesozoic structural inheritance, Oligo-Miocene extension, Mio-Pliocene orogenic shortening with the respective tectonic inversion associated to the uplift of the Andean western margin. Miocene volcano sedimentary units (Abanico Formation) and Pliocene syn-orogenic volcanic units form the deformed host distrital structure. These rocks are part of a trench-linked Andean deformation belt that accommodates EW shortening by NS- strike faults and NS-axes fault related folds. This structural belt controls the uplift of the western margin of the Andes by tectonic inversion of Miocene rift-type structural geometries. The reservoir structure is interpreted by the emplacement of a batholith in the core of the transfer zone between two NS-strike reverse faults, where the ore bodies are located in the center of an anticline general structure showing NW-SE mineralization trend. In turn, NE trending faults dislocate ore bodies in the transfer zone. The reservoir structure is interpreted by the emplacement of a Mio-Pliocene syntectonic batholith in the middle of a transfer zone between two NS-strike reverse faults, where the ore bodies are located in the axis of the anticlinal general structure. Passive seismic tomography results suggest a NNW-strike zone formed by fractured or/and hydrated rocks. This zone is spatially

    Full Text Available This study aims to analyze the diet and trophic ecomorphology of Odontesthes bonariensis, relating these features with species' abundance in the natural environment and in the Salto Caxias reservoir (at Iguaçu river after the reservoir's formation. The samples were carried out before (from March 1997 to February 1998- pre and after (from October 1998 to February 2001 - post 1 and 2 the damming. The stomach contents of 218 individuals were analyzed by occurrence and volumetric methods. O. bonariensis' diet is based on insects, scales, plants and detritus. Microcrustaceans (Cladocera and Copepoda were the main items, allowing the characterization of the species as zooplanktivore. The species has a superior position and protractible mouth, with small teeth, creating a serrated pattern, uniformly lined side by side. There are many gill rakers, that are long and close together (typical of filtering fishes; the stomach is ill defined and the intestine is short. There was a gradual increase of O. bonariensis' abundance during the period of field study, mainly after the second year of damming. This fact seems to be closely related with the high abundance and availability of zooplankton in the dammed environment, and also with the ability of the species to exploit this resource.Este estudo teve como objetivo analisar a dieta e ecomorfologia trófica de Odontesthes bonariensis, relacionando estes aspectos à abundância da espécie, no ambiente natural e após a formação do reservatório de Salto Caxias, Rio Iguaçu.

    Detailed stratigraphic analysis of the Early Permian Rio Bonito and Palermo Formations of the Parana Basin in the region of Sao Gabriel County has been used for a study on reservoir characterization of paralic sandstones. Two main depositional systems were recognized, a fluvial-dominated delta system and a wave-dominated barrier island system. The succession is divided in two third-order depositional sequences, enclosing thirteen fourth-order para sequences. This high-resolution stratigraphic framework was the base for a multi scale approach on reservoir characterization of the sandstone bodies. Reservoir heterogeneities are discussed, staring from the scale of depositional sequence (heterogeneity level 1), passing down to heterogeneity at the scale of systems tracts (heterogeneity level 2) and finalizing with an approach at para sequence scale (heterogeneity level 3). Main control on heterogeneity at the first level is base-level variation as generating mechanism for un conformities at the sediment type and rate. At the second level, the reservoir heterogeneity is controlled by the lateral and vertical variations in thickness of particular systems within the different systems tracts, and at the third level, the heterogeneity occurs controlling reservoir continuity and connectivities between reservoirs. The study supplies a model which is useful as a predictive tool for similar geologic settings in producing oil fields. (author)

  12. Ontario electricity bill review

    International Nuclear Information System (INIS)

    Findings of an independent review of charges to electricity bills and recommendations to assist in the development of a standard, province-wide residential electricity bill for Ontario are discussed. The review was requested by the province's Minister of Energy in an effort to dispel growing confusion about the variations in customer billing practices used by the province's 90+ local distribution companies. Key recommendations and findings were as follows: (1)Consumer bill formats issued by local distribution companies should be more consumer-friendly, adhere to minimum design standards, adapt uniform terminology and common line charges; (2) charges on customer bills should be grouped into four standard line items, with full details available to customers: the four line items should be a basic service charge, a charge for delivering electricity to the customer, a charge for the electricity itself, and a separate charge for retiring the outstanding debt of the former Ontario Hydro; (3) bills should take advantage of opportunities for promoting province-wide energy conservation, such as encouraging the long-term use of interval meters, presenting historical consumption data on residential bills on a period-to-period basis, and education and communications initiatives. Details of the recommendations, including the calculation of the fixed and variable components of usage charges, an explanation of the concept of electricity system loss adjustments, a method for phasing in the recommendations, and the anticipated benefits to consumers are provided

    Full Text Available An evaluation was made of the quality of samples of water and sediment collected from a series of reservoirs in the Tietê River (SP, based on limnological and ecotoxicological analyses. The samples were collected during two periods (Feb and Jul 2000 from 15 sampling stations. Acute toxicity bioassays were performed using the test organism Daphnia similis, while chronic bioassays were carried out withCeriodaphnia dubia and Danio rerio larvae. The water samples were analyzed for total nutrients, total suspended matter and total cadmium, chromium, copper and zinc concentrations, while the sediment samples were examined for organic matter, granulometry and potentially bioavailable metals (cadmium, chromium, copper and zinc. The results obtained for the limnological variable, revealed differences in the water quality, with high contribution of nutrients and metals for Tietê and Piracicaba rivers, besides the incorporation and sedimentation, consequently causing a reduction of materials in Barra Bonita reservoir, thus promoting the improvement of the water quality in the other reservoirs. The toxicity bioassays revealed acute toxicity for Daphnia similis only in the reservoirs located below Barra Bonita dam. On the other hand, chronic toxicity for Ceriodaphnia dubia and acute for Danio rerio showed a different pattern, decreasing in magnitude from Barra Bonita to Três Irmãos, demonstrating an environmental degradation gradient in the reservoirs.O presente trabalho visou avaliar a qualidade de amostras de água e sedimento dos reservatórios em cascata do rio Tietê (SP através de análises limnológicas e ecotoxicológicas.

  17. Badali recommends simplified bills

    International Nuclear Information System (INIS)

    A report on the variety of retail electricity bills across the province, authored by Salvatore Badali of Deloitte Consulting, was recently released by the Ontario Government. The report was commissioned by the Government to examine the underlying reasons for the significant format differences and the wide variation of fixed and variable charges among the approximately 95 local electricity distribution companies across the province. Regarding the appropriateness of the charges the report recommends common definitions for local distribution company (LDC) fixed and variable costs, and consideration of options for reducing LDC charges, mainly by consolidating the sector and sharing such services as customer billing, accounting and out sourcing operations. Seven recommendations deal with bill simplification. These include bills that are clear and easy to read and provide sufficient information for consumers to verify charges; promote energy conservation, e.g. by including historical information; allow comparisons between retail suppliers and distributors; accommodate revenue collection, marketing needs and other billing services. The report also recommends clearly defined and consistently used terminology for standardized line items, suggests ways to provide consumer information in a form useful for making energy conservation decisions, development of an LDC scorecard to enable stake holders to compare their own LDCs with LDCs around the province, creation of a conservation and bill calculation website, consideration of further use of shared services, and solutions to address the removal of line losses from invoices

During gonadal maturation, the females showed a low hepatosomatic index, suggesting that hepatic substances are possibly transferred from liver to ovaries. During the reproductive period, this fish had lower stomach repletion and coelomic fat indexes, indicating that the species eat less and consume more fat reserves. The weight of the ovaries influenced positively the condition factor (K1, since the lowest K2 values (without the gonads weight, were obtained during maturation, confirming the influence of the weight of the ovaries upon the physiological condition of the females.O 'saguiru' Steindachnerina insculpta, peixe teleósteo detritívoro que ocorre no reservatório de Furnas, bacia do alto Paraná, Minas Gerais, apresenta período reprodutivo prolongado que se estende de setembro a março, com desova parcelada. Durante a maturação gonadal, fêmeas apresentaram baixos valores do índice hepatossomático, sugerindo que possivelmente, substâncias hepáticas são transferidas do fígado para os ovários. Durante o período reprodutivo, os peixes desta espécie apresentam índices de repleção estomacal e de gordura celômica baixos, indicando diminuição da atividade alimentar e consumo de reservas.

    Full Text Available Este estudo analisa as propostas de projetos de lei para o controle sanitário da propaganda de bebidas alcoólicas nos meios de comunicação de massa, apresentados ao Congresso Nacional entre 1988 e 2004. Inserido em um debate de natureza ético-política, o controle sanitário dessa propaganda é uma questão controversa, pois os interesses pela proteção da saúde se confrontam com os interesses comerciais mesmo ante as evidências científicas de que o consumo crescente de álcool é um problema social e de saúde no mundo contemporâneo. Realizou-se a análise de conteúdo de 67 documentos, na qual se mostra que as propostas formuladas, majoritariamente, apresentam-se como estratégias de enfrentamento a essa propaganda, procurando desvincular valores associados ao produto que interferem na construção da identidade social de crianças e adolescentes e limitar o conteúdo das mensagens veiculadas nos meios de comunicação de massa, dado que este segmento está mais vulnerável. O estudo evidencia complexos desafios para o controle da propaganda, que implicam repensar a própria atuação do Estado ante esse relevante problema de Saúde Pública.This study analyses law bills towards the sanitary control of alcohol advertisement in the mass media presented to the Brazilian Congress from 1988 to 2004. The sanitary control of this advertising is a controversial issue bringing about an ethical-political debate in which the health-protecting interests conflict with commercial ones even after scientific evidence has established increasing alcohol intake as a health and social issue worldwide. The content analysis of 67 of such law bills was carried out, and these proposals were shown to consist mostly of strategies to both cope with alcohol advertising by dissociating from the product those values that might interfere with the children and teenagers' building of their social identity and limit advertisement contents in the mass media given the

    Full Text Available This study aimed at evaluating potential differences among the bacterial communities from formation water and oil samples originated from biodegraded and non-biodegraded Brazilian petroleum reservoirs by using a PCR-DGGE based approach. Environmental DNA was isolated and used in PCR reactions with bacterial primers, followed by separation of 16S rDNA fragments in the DGGE. PCR products were also cloned and sequenced, aiming at the taxonomic affiliation of the community members. The fingerprints obtained allowed the direct comparison among the bacterial communities from oil samples presenting distinct degrees of biodegradation, as well as between the communities of formation water and oil sample from the non-biodegraded reservoir. Very similar DGGE band profiles were observed for all samples, and the diversity of the predominant bacterial phylotypes was shown to be low. Cloning and sequencing results revealed major differences between formation water and oil samples from the non-biodegraded reservoir. Bacillus sp. and Halanaerobium sp. were shown to be the predominant components of the bacterial community from the formation water sample, whereas the oil sample also included Alicyclobacillus acidoterrestris, Rhodococcus sp., Streptomyces sp. and Acidithiobacillus ferrooxidans. The PCR-DGGE technique, combined with cloning and sequencing of PCR products, revealed the presence of taxonomic groups not found previously in these samples when using cultivation-based methods and 16S rRNA gene library assembly, confirming the need of a polyphasic study in order to improve the knowledge of the extent of microbial diversity in such extreme environments.Este estudo teve como objetivo comparar as comunidades bacterianas de amostras de água de formação e de óleo de reservatórios de petróleo brasileiros com diferentes graus de biodegradação usando a técnica de PCR-DGGE.

  10. Coal Industry Bill

    International Nuclear Information System (INIS)

    Privatization of the British hardcoal mining industry enters into the final stage. The statutory basis will be created by the 'Coal Industry Bill' being discussed at present in Parliament and which will probably be signed by the Queen in summer 1994 and then become a law. The 'Coal Industry Bill' stipulates in detail in which way British Coal will be dissolved and which competences will be transferred to the newly created coal authority. The allocation of powers and responsibilities to successor organizations will be determined as well as the role of the state for e.g. pension and concessionary commitments. Another important subject is the distribution of the charges for mining damages, and reclamation and environmental protection. (orig.)

Os peixes foram coletados, mensalmente, de março/2000 a fevereiro/2001 com redes de espera e de arrasto. Foram analisados 199 conteúdos estomacais por meio do método volumétrico. No reservatório, a dieta foi composta basicamente por insetos durante todo o período analisado e independente do tamanho dos exemplares. Na baía Sinhá Mariana, a importância dos itens variou mensalmente, sendo que vegetais, peixes e escamas predominaram em alguns meses. Variações ontogenéticas foram observadas na baia, sendo que os menores indivíduos (3,6 a 8,0 cm consumiram predominantemente insetos, detrito-sedimento e escamas, enquanto os maiores (16,8 a 21,2 cm alimentaram-se essencialmente de peixes. Os alimentos de origem terrestre dominaram a dieta dos peixes do reservatório, enquanto os de origem aquática predominaram na baía. Os resultados obtidos mostraram a elevada plasticidade alimentar de P. maculatus e o comportamento oportunista da espécie no reservatório, demonstrando sua habilidade em consumir recursos temporariamente disponíveis, como os alimentos de origem terrestre, principalmente insetos, que são disponibilizados em reservatórios recém-formados.Temporal and ontogenetic changes in the diet of Pimelodus maculatus were assessed in the Manso Reservoir and Sinhá Mariana lagoon, Mato Grosso State.

Houve flutuações na abundância dos rotíferos um mês após oscilações na abundância do fitoplâncton. A maior parte das correlações entre as abundâncias de espécies de rotíferos e do fitoplâncton foi positiva. Alguns táxons como Filinia longiseta, Keratella lenzi e K. cochlearis apresentaram variação temporal definida e semelhante a outros reservatórios eutróficos. A ausência de padrões claros de distribuição em algumas espécies foi atribuída a hidrodinâmica do reservatório, o qual foi construído recentemente, e as condições climáticas adversas durante o período de estudo, como as chuvas intensas no inverno

    The author has identified the following significant results. HCMM day/night coverage 12 hours apart cannot be obtained at 26 deg N latitude; nor have any pairs 36 hours apart been obtained. A day-IR scene and a night scene for two different dates were analyzed. A profile across the test site for the same latitude shows that the two profiles are near mirror images of each other over land surfaces and that the temperature of two large water bodies, Falcon Reservoir and the Gulf of Mexico, are nearly identical on two dates. During the time interval between overpasses, the vegetative cover remained static due to winter dormancy. The data suggest that day/night temperature differences measured weeks apart may yield meaningful information about the contrast between daytime maximum and nighttime minimum temperatures for a given site.

    A central challenge of integrated water management is the design and implementation of policies to allocate water to both humans and the environment in a sustainable manner. This study uses the results from a reach-scale water-planning model to quantify and compare the economic benefits of two water management policies: (1) a business as usual (Baseline) policy and (2) a proposed reservoir re-operation policy to provide environmental flows (EFs). Results show that the EF policy would increase water supply profit, slightly decrease recreational activities profit, and reduce costs from flood damage and environmental restoration compared to the Baseline policy. In addition to supporting ecological objectives, the proposed EF policy would increase the economic benefits of water management objectives.

    Full Text Available O objetivo deste trabalho é o de apresentar uma metodologia que avalia e quantifica as perdas agropecuárias que ocorrem quando da construção de reservatórios para a geração de energia elétrica. Foram estudados sete reservatórios da CEMIG situados no Estado de Minas Gerais. A produção agropecuária foi obtida de acordo com dados do IBGE relativos a 2001. As áreas municipais alagadas foram calculadas com base em dados georeferenciados fornecidos pela ANEEL. Ao final, os valores das externalidades foram comparados ao custo da energia elétrica e ao PIB municipal para a avaliação da significância dos resultados. Verificou-se que quanto maior o valor da área municipal alagada, mais relevante será a externalidade. Como exemplo, o município de Grupiara tem 40% de suas terras inundadas pelo lago de Emborcação. Entre todas as localidades estudadas, esta foi aquela onde a externalidade agropecuária foi mais relevante.The objective of this work is to present a methodology that evaluates and quantifies the agricultural and livestock losses that happen when reservoirs for the electric power generation are constructed. Seven CEMIG reservoirs, located in Minas Gerais State were studied The agricultural and livestock production were obtained in agreement on with IBGE 2001 data. The municipal areas were calculated based in georeference data supplied by ANEEL. The externalities values were compared to the electric power cost and to municipal gross domestic product to evaluate the significance of the results. It was verified that as larger is the value of the municipal flooded area, more relevant is the externality. As example, the city of Grupiara has 40% of their lands flooded by the lake of Emborcação. Among all the cities studied, that was the one where the agricultural and livestock externalities were more significant.

Com o objetivo de caracterizar os pescadores e as pescarias do reservatório, criar cenários de aumento do esforço pesqueiro e prever os momentos de conflito pela escassez de recursos, foram levantadas informações da literatura e realizadas duas campanhas de coleta de dados nos anos de 1999 e 2000, envolvendo entrevistas com líderes comunitários e pescadores. As seguintes variáveis foram consideradas: desembarque por espécie-alvo (de acordo com os registros fornecidos pelas colônias de pescadores, artes de pesca, estratégias dos pescadores, conflitos e formas de apropriação do espaço e rendimentos da atividade. Estas variáveis foram inseridas em um modelo dinâmico, simulado no software Vensim PLE para um período de 10 anos a partir de 1999.

    Full Text Available Birds are the most important reservoirs of the influenza virus. Its maintenance in its natural hosts, including man, allows the influenza virus to reassorts its strains. The recent report of an avian influenza A (H5N1 virus in humans, was in a child with fatal respiratory illness in China, 1997. The current study was conducted to elucidate the transportation of the influenza by birds that migrate, annually, through the both Northern and Southern hemispheres, with special attention paid to the Vireo olivaceus [Juruviara(BR or Red-eyed vireo(USA] species, which travels from the USA to Brazil, and vice versa, and the Elaenia mesoleuca [Tuque(BR or (USA] species that flies over the entire Southern Hemisphere. There are two species of birds, which breed and migrate in São Paulo State, Brazil, and which were demonstrated to carry Influenza virus, were selected. The viral particles isolated were observed by electron microscopy. The influenza virus was detected by the House Duplex/PCR and Gloria molecular biology tests. The results demonstrated that the Elaenia mesoleuca and Vireo olivaceus bird species are carrying the Influenza virus whilst crossing both the Northern and Southern hemispheres. To understand the role that these migrating birds may play in epidemic influenza, in Brazil, characterization of avian influenza subtypes will be done.Os mais importantes reservatórios do vírus influenza são os pássaros.

    Full Text Available Aim: This study assessed the water quality from the springs and river mouths of the fifth-order tributaries which compose the reservoir of Marechal Mascarenhas de Morais HPS in the middle Rio Grande watershed, Minas Gerais, Brazil. Methods: It has been studied 14 tributaries distributed in the reservoir, two points for tributary - spring and river mouth. Eighteen limnological variables added to the Rapid Assessment Protocol and Trophic Level Index were evaluated. The benthic macroinvertebrates had been collected by the use of a granulometric sieve and a Petersen-type sampler. Results: The cluster analysis of limnological data revealed the existence of two tributary groups. Group I consisted of eutrophic tributaries degraded by human activities, while group II exhibited good water quality and well-preserved environments. Group I was divided into two subgroups, Ia tributaries were characterized by being altered by human activities, while the Ib subgroup was composed of highly impacted tributaries. By ordering the PCA, it can be observed spatial segregation of groups, where the most polluted tributaries were separated from those which are better preserved. A total of 8,987 individuals belonging to 36 families of macroinvertebrates were identified. The family Chironomidae was the most abundant. There was no significant difference in total abundance and the richness of macroinvertebrates taxa inhabiting springs, by those who inhabiting the river mouths. Conclusions: It was noticed that most of the tributaries which supply and composes the reservoir are already degraded and have low quality water. It is observed that the human presence drastically affected water quality and faunal composition of tributaries. Thus, it is necessary a complementary study of the tributaries in working with issues related to reservoirs, as these components have direct influence on the water quality and composition of these lentic environments.Objetivos: O trabalho avaliou

    Full Text Available The edafoclimatic conditions of the Brazilian semiarid region favor the water loss by surface runoff. The state of Ceará, almost completely covered by semiarid, has developed public policies for the construction of dams in order to attend the varied water demand. Several hydrological models were developed to support decisive processes in the complex management of reservoirs. This study aimed to establish a methodology for obtaining a georeferenced database suitable for use as input data in hydrological modeling in the semiarid of Ceará. It was used images of Landsat satellite and SRTM Mission, and soil maps of the state of Ceará. The Landsat images allowed the determination of the land cover and the SRTM Mission images, the automatic delineation of hydrographic basins. The soil type was obtained through the soil map. The database was obtained for Jaguaribe River hydrographic basin, in the state of Ceará, and is applicable to hydrological modeling based on the Curve Number method for estimating the surface runoff.As condições edafoclimáticas do semiárido brasileiro favorecem a perda de água por escoamento superficial.

    Full Text Available We assessed spatial and seasonal changes in the diet of Oligosarcus hepsetus in order to describe the strategy developed by this species that allows their very high abundance in Lajes reservoir, Rio de Janeiro, Brazil. Fish samplings were carried out using gill nets, deployed during ca. 12 and 24 hours, between April 2001 and May 2002. A total of 289 individuals were examined, of which 97 showed gut contents. We used the index of relative importance (IRI to compare probable dietary shifts, and the frequency of occurrence (% OC to analyze possible ontogenetic influences on feeding. O. hepsetus showed carnivorous habits, feeding preferably on fish and insects, the latter of which occurred in 71.0% of the guts presenting contents. O. hepsetus consumed different items along the three reservoir zones: insects (61.0% IRI and Cichla monoculus (38.9% IRI in the lower zone; Lepidoptera (57.0% IRI in the middle zone; and C. monoculus (77.0% IRI in the upper zone. Food items changed seasonally with C. monoculus predominating in autumn 2001, and Hymenoptera and Lepidoptera in the winter. In spring almost all food was Lepidoptera (99.8% IRI, while in the summer Hemiptera dominated in the diet. In autumn 2002 Hemiptera (97.0% IRI was dominant, in significant contrast with the previous autumn. Individuals smaller than 190 mm SL fed heavily on insects, while fishes predominated in the diet of individuals larger than 190 mm SL. Shifts in prey-capture ability among length classes suggest decreasing intraspecific competition. A higher food plasticity seems to be the strategy employed by this opportunist species, which used food resources available in the reservoir.Foram analisadas variações na dieta de O. hepsetus conforme comparações espaciais e sazonais, com o objetivo de descrever a estratégia desenvolvida por essa espécie que permite sua elevada abundância no reservatório de Lajes, Rio de Janeiro, Brasil.

    abundance in plankton of different reservoirs of Paraná State and the importance of hydrodinamical and morphometrical factors on determining these patterns. Thirty reservoirs studied are located in six different watersheds, including environments with variable area, morphometry and age. Sampling were carried out in July and November 2001, dry and rainy seasons, respectively. Samples were obtained at the surface of reservoirs, in the lacustrine region, using a motorized pump (600 liters per sample and a plankton net with a mesh size of 68µm. Testate amoebae were registered in 23 of 30 reservoirs.Higher density were observed in JMF, Salto do Meio, Melissa, Mourão and Salto do Vau reservoirs, during dry season, and JMF, Salto Osório, Salto do Meio and Melissa reservoirs, during wet season These reservoirs present similar characteristics, as reduced depth and morphometric dimensions Besides that, most of them have hydrodynamical features similar to lotic environments, due to presenting high current velocity. On the other hand, testate amoebae were absent or presented low density, in general, in reservoirs with higher dimensions and depth. Instead of expected, seasonally, higher densities values were observed during dry season, for the most of studied reservoirs. These results can be related to the fact that the reservoirs during dry season have a remarkable reduction of their dimentions (area and depth, determining a greater influence of the benthonic organisms to the composition and abundance of the protozooplankton community

  4. Atomic Weapons Establishment Bill [Money

    International Nuclear Information System (INIS)

    The debate concerns the authorisation of payment of the money required to reorganise the atomic weapons establishment in the United Kingdom provided for in the Atomic Weapons Establishment Bill in progress through Parliament. In the Bill the contractorisation of the establishment is recommended and some sort of Government owned company operated scheme set up. The debate lasted about half an hour and is reported verbatim. The issues raised concerned the actual sums likely to be incurred in the formation of a Company to carry out the designated activities of the Bill. These are connected with the research, development, production or maintenance of nuclear devices and the premises needed. The government spokesman suggested the sums required to support the Bill would not be large and the resolution was agreed to without a vote. (UK)

In order to obtain the PCAP, the observed maximum depth of colonization of the anchored macrophytes before impoundment and the hypsographic curves were used. The species inhabiting the pre-impoundment area were classified according to the different bioforms before the inclussion in the analysis. The areal extent of PCAP (from depths between 0-4 m could reach 275 km² at 76 m above sea level (current water level, whereas at 82 m above sea level (final filling level the littoral zone will be increased by about 21.5%. The potential area for geophytes was estimated to be 99 km²; 131 km² for root-floating leaved plants and 120 km² for submerged plants, at 76 m above sea level. At 82 m above sea level, the geophytes could reach 271 km². The data for wind frequency, velocity and fetch, together with depth were used to calculate shallow and sheltered areas in which free floating plants could find favourable conditions to initial colonization.

    Science.gov (United States)

    In an 89 to 11 vote the Senate passed a clean air bill aimed at reducing pollution by the turn of the century by imposing tougher controls on American industry. The bill is the first revision of the Clean Air Act of 1970 in 13 years and calls for new limits on auto pollution to clean up smog in most U.S. cities, decreasing by half emissions by power plants that cause acid rain to protect the ecology, and increasing technological controls on factories to protect against cancer-causing and toxic substances. The bill will add about $20 billion per year to the estimated $33 billion cost of complying with current pollution laws.

    The Bill contains a number of unrelated proposals. The first would increase the financial limit imposed on British Nuclear Fuels plc by Acts of Parliament to Pound 2,000 million in line with current investment plans. The second would enable the Health and Safety Executive to recover the costs of nuclear safety research which it sponsors, from nuclear site licensees and applicants for licences. The next two proposals make minor technical amendments to the rules on insurance cover for meeting third party compensation claims in the event of nuclear incidents. Finally, the Bill would enable the United Kingdom to ratify the International Convention on Assistance in the case of nuclear accident or radiological emergency (mutual assistance convention). The Bill was debated for half an hour and is reported verbatim. In particular the financing of the Thermal Oxide Reprocessing Plant at BNFL's Sellafield site was discussed.

  20. Reservoir management

    International Nuclear Information System (INIS)

    A reservoir's life begins with exploration leading to discovery followed by delineation of the reservoir, development of the field, production by primary, secondary and tertiary means, and finally to abandonment. Sound reservoir management is the key to maximizing economic operation of the reservoir throughout its entire life. Technological advances and rapidly increasing computer power are providing tools to better manage reservoirs and are increasing the gap between good and neutral reservoir management. The modern reservoir management process involves goal setting, planning, implementing, monitoring, evaluating, and revising plans. Setting a reservoir management strategy requires knowledge of the reservoir, availability of technology, and knowledge of the business, political, and environmental climate. Formulating a comprehensive management plan involves depletion and development strategies, data acquisition and analyses, geological and numerical model studies, production and reserves forecasts, facilities requirements, economic optimization, and management approval. This paper provides management, engineers geologists, geophysicists, and field operations staff with a better understanding of the practical approach to reservoir management using a multidisciplinary, integrated team approach

    This article comments the slight decrease of the French energy bill in 2007 and its evolution since 1970, as well as the energy price fluctuations during 2007. While noticing the importance of the dollar fall, the authors discuss the evolution of oil product prices and its different indicators (crude oil annual average quotation, Brent annual average quotation, and imported oil annual average price), the evolution of natural gas prices, of coal prices, of electricity prices. The global decrease of energy imports is then discussed, including quantities of imported crude oil from various origins, refined products, gas from various origins as well, solid mineral fuels. The balance between exports and imports is commented as a whole, and with some particular countries, enabling an assessment of energy independence. The bill evolution for oil and for gas is briefly discussed, and the global value is assessed with respect to the French GDP or as an amount of work days for French inhabitants. Several graphs and tables are given, gathering several data which have been discussed: energy trade (imports, exports, and bill), comparison of bill with other economic aggregates, average prices of imported energy expressed in dollars and in euros, average price of imported crude oil, etc

  18. 2003 energy bill of France

    International Nuclear Information System (INIS)

    The 2003 energy bill of France shows a 4.7% increase (22.71 billions of euros) after 2 years of decay (-5.5% in 2002 and -2.5% in 2001). It represents 1.47% of the total gross domestic product (1.43% in 2002), a level comparable with the one of 1987. The rise of the bill comes from the net gas imports (+9.1%) and the drop of net power exports (-21.6%), while the petroleum bill remains stable (+0.2%). In 2003, the energy imports and exports represented 30.68 billions of euros (+3.5% with respect to 2002) and 7.97 billions of euros (+0.2%) respectively. In the detail, energy prices have changed in a very contrasted way: strong rise of crude oil prices (+16.8%) and imported gas prices (+29.9%). On the other hand, the price of exported electricity shows a -7.6% decay. The quantity import balance shows a 2.8% decay under the opposite effects of: the 1.1% decay of the end-use consumption, the strong 2003 coal and gas de-storage following a stronger 2002 storage, the rise of the domestic primary power generation, and the colder 2003 climate.

    Full Text Available Paraitinga and Biritiba reservoirs are part of Sistema Produtor Alto Tietê and they play an important role at the public water supply. The purpose of this study is to understand the mass balance of nitrogen and phosphorus that can influence the eutrophication process in reservoirs during the filling phase, and provide information for the implementation of mechanisms to manage water quality. Water samples were collected from August 2005 until May 2006. Concentrations of total phosphorus (PT and total nitrogen (NT were measured and the mass balance and loads were estimated. Paraitinga reservoir presented retention of NT and PT during the dry season and export during therainy season; whilst at Biritiba reservoir we evidenced retention of NT and PT for both dry and rainy seasons. The annual balance demonstrated that during the reservoirs filling process, the systems retain NT and PT. The retention of nutrients into the system indicatesthat the environments have been modified leading to eutrophication and its consequences, and that it is necessary to outline strategies in order to mitigate the problem and suggest implementation of techniques to reduce the diffuse load.Os reservatórios Paraitinga e Biritiba estão inseridos no Sistema Produtor Alto Tietê, com elevada importância para o abastecimento público. O objetivo do trabalho foi compreender o balanço de massa donitrogênio e fósforo os quais podem influenciar o processo de eutrofização em reservatórios durante o enchimento e subsidiar informações para implantação de mecanismos de gerenciamento da qualidade de água. Coletas trimestrais de água foram realizadas no período de um ano de agosto/2005 a maio/2006. As concentrações de fósforo total (PT e nitrogênio total (NT foram medidas, e estimadas as cargas e o balanço de massa.

Foram consideradas como variáveis a profundidade (superfície, 3,5 e 7,0 m, as espécies de plantas aquáticas (Eichhornia crassipes, Brachiaria subquadripara e Pistia stratiotes e o tipo de processamento a que estas foram submetidas (planta inteira, planta picada manualmente e com aplicação de fogo. Este estudo indicou que as espécies E. crassipes e P. stratiotes foram rapidamente decompostas no reservatório, ao contrário de B. subquadripara. Um outro fator importante observado foi a similaridade na decomposição das plantas, independentemente da profundidade testada. Essas diferenças devem ser consideradas na elaboração de planos de manejo e na previsão do impacto ambiental de programas de controle de plantas aquáticas.A study on aquatic weed decomposition was carried out at the Americana-SP reservoir in Brazil, to compare degradation rate of the plants in the reservoir's water itself. Three variables were considered as treatments: depth (surface, 3.5 and 7.0 m; aquatic weed species (Eichhornia crassipes, Brachiaria subquadripara, and Pistia stratiotes and type of handling the aquatic weeds (whole plant, hand cut plant, and burnt plant. The results indicated that the species E. crassipes and P. stratiotes had a fast decomposition in the reservoir, unlike B. subquadripara. These differences must be considered in the elaboration of management plans and prediction of environmental impact of aquatic plant control programs. The most positive aspect of the study was to demonstrate that decomposition at 3.5m and 7.0 m of depth had practically the same speed observed on the surface.

    This paper addresses the questions related to the cost of China's bank restructuring and how it has been financed. We first propose a framework for recognizing losses. Then, we examine the recent major moves by the Chinese Government to repair the country's bank balance sheets. Finally, we explore the implications of the Chinese Government's methods of funding bank restructuring. We find that the Chinese Government has been decisive in confronting the costly task of bank restructuring. So far, Chinese taxpayers have paid most of the bill for bank restructuring.

    Full Text Available Reproductive biology and feeding of Curimatella lepidura (Eigenmann & Eigenmann, 1889 were studied in Juramento reservoir, São Francisco River basin, Southeastern Brazil. Histological analyses and gonadosomatic indexes revealed females and males in reproductive activity from October to March and total spawning occurring from January to March coupled with the peak of spermiating males. In the dry season, the fishes accumulated energetic reserves for reproduction during a short rainy season. The species presented sexual dimorphism, being females larger than males and sexual maturation occurring close to 7.7 cm standard length for females and 7.1 cm for males. C. lepidura presented iliophagous feeding habit, ingesting mainly sediment/detritus and a small amount of acari, algae, Tricoptera insects and Ostracoda crustaceans, suggesting a probable role in nutrient recycling of the Juramento reservoir.A biologia reprodutiva e alimentação de Curimatella lepidura (Eigenmann & Eigenmann, 1889 foram estudadas no reservatório de Juramento, Bacia do rio São Francisco, Sudeste do Brasil. Análises histológicas e índices gonadosomáticos mostraram fêmeas e machos em atividade reprodutiva de outubro a março e desova total ocorrendo de janeiro a março coincidindo com pico de espermiação. Na estação seca, os peixes acumularam reservas energéticas para a reprodução durante curta estação chuvosa. A espécie apresentou dimorfismo sexual, sendo as fêmeas maiores do que os machos e, a maturação gonadal ocorreu em torno de 7,7 cm de comprimento padrão para as fêmeas e 7,1 cm para os machos. C. lepidura apresentou hábito alimentar iliófago, ingerindo predominantemente sedimento/detrito e, em menor proporção, ácaros, algas, insetos Tricoptera e crustáceos Ostracodas sugerindo provável papel na reciclagem de nutrientes do reservatório de Juramento.

Portanto, o paradigma define o que seria estudado, quais as questões a serem perguntadas, quais ferramentas seriam usadas e quais as normas a serem seguidas na interpretação dos resultados. O objetivo desse estudo é analisar como o manejo da pesca emergiu e se desenvolveu no Brasil considerando o progresso da ciência como uma série de paradigmas. Ações de manejo relatadas para a pesca não são freqüentes no Brasil e quando aplicadas não apresentaram bons resultados, porque usualmente foram baseadas em informações técnicas e científicas inadequadas ou em paradigmas desenvolvidos em regiões temperadas. As escadas de peixes foram as primeiras tentativas para minimizar os impactos dos barramentos, seguidas pela regulação da pesca e peixamentos. Entretanto, parece que o paradigma que norteava estas pesquisas (importados dos Estados Unidos da América não foi apropriado para o manejo de reservatório na maioria do território brasileiro. Além disso, outros motivos podem ter contribuído para alguns fracassos das ações de manejo, tais como: i dados disponíveis inadequados e insuficientes; ii a abordagem inadequada usada para realizar o manejo; iii ausência de estudos de monitoramento; iv políticas inadequadas e v deficiência na integração entre as companhias hidrelétricas.

  19. Modeling and Managing Risk in Billing Infrastructures

    Science.gov (United States)

    Baiardi, Fabrizio; Telmon, Claudio; Sgandurra, Daniele

    This paper discusses risk modeling and risk management in information and communications technology (ICT) systems for which the attack impact distribution is heavy tailed (e.g., power law distribution) and the average risk is unbounded. Systems with these properties include billing infrastructures used to charge customers for services they access. Attacks against billing infrastructures can be classified as peripheral attacks and backbone attacks. The goal of a peripheral attack is to tamper with user bills; a backbone attack seeks to seize control of the billing infrastructure. The probability distribution of the overall impact of an attack on a billing infrastructure also has a heavy-tailed curve. This implies that the probability of a massive impact cannot be ignored and that the average impact may be unbounded - thus, even the most expensive countermeasures would be cost effective. Consequently, the only strategy for managing risk is to increase the resilience of the infrastructure by employing redundant components.

Neste sentido, aplicou-se o processo TMDL (total maximum daily load, desenvolvido pela Agência de Proteção Ambiental dos Estados Unidos (EPA, para o P, na área de drenagem de contribuição ao futuro reservatório Piraquara II, bacia hidrográfica do rio Piraquara, Paraná. O processo TMDL determina a quantidade máxima de cargas de um poluente que um corpo d'água pode receber sem violar os padrões estabelecidos de qualidade da água e aloca cargas deste poluente entre fontes de poluição pontuais e difusas. No presente estudo, utilizou-se o método TMDL, com o objetivo de demonstrar ser ele uma ferramenta útil no processo de gestão dos recursos hídricos. Simularam-se cenários de uso do solo, por meio de modelagem matemática, até obter-se uma concentração de P total no reservatório abaixo da faixa limite para ocorrência de eutrofização, de 0,025 a 0,10 mg L-1, estabelecida no estudo. Realizou-se uma simulação de uso atual do solo, visando prever a condição inicial de qualidade da água no corpo d'água, na qual a concentração de P total no reservatório resultante não atendeu ao padrão estabelecido. Procedeu-se a uma segunda simulação com adoção das medidas de controle, recomposição de mata ciliar e plantio direto, para reduzir a exportação de carga de P total da bacia. Obteve-se uma melhoria na qualidade da água do reservatório, indicando que as medidas adotadas foram suficientes para atingir o padrão estabelecido, o que demonstra a aplicabilidade do método.For the implementation and operation of the Brazilian Federal law on water resources of 1997 it is indispensable to use planning tools that take into account the effect of

  6. Rio report

    International Nuclear Information System (INIS)

    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 Os autores descrevem o resultado de dois anos de investigação de um foco de Leishmaniose Tegumentar Americana (LTA, ocorrida em área urbanizada em um conjunto habitacional na cidade da Manaus-AM. Chama atenção o fato de que este não é o padrão de ocorrência de surtos da doença na região, e sim interrupção da transmissão após urbanização. Foram investigados os animais considerados reservatórios em potencial para a leishmaniose em domicílios humanos e em áreas de floresta adjacentes. Foram testados anticorpos contra Leishmania spp em amostras de sangue de cães e detectada reatividade pela reação de imunofluorescencia indireta em oito (20,51 % dos examinados. Entre os animais silvestres examinados a espécie Didelphis marsupialis foi predominante, com 20 exemplares capturados, sendo encontrados homoflagelados em três destes e lesões suspeitas de leishmaniose cutanea em dois. Acredita-se que um assentamento populacional desordenado ocorrido nas adjacências tenha causado o deslocamento das populações de vetores e reservatórios naturais em direção às casas do conjunto Hiléia propiciando o surto.This is the result of a two year follow-up of a Cutaneous Leishmaniasis (CL foci in the Hileia urban neighborhood in Manaus. It is important to point out that this is not the usual pattern of Leishmaniasis occurrence in this area. The authors investigated the animal potential reservoir in households and in the surrounding forest area. Samples were tested for leishmaniasis antibodies by RIFI. Eight (20.51% of the examined domestic dogs showed reactivity. In captured wild animals, the Didelphis marsupialis was predominant in twenty specimens, three with homoflagelated in the blood and two with suspicious cutaneous lesions. We believe that the disordered population growth in the nearby area pushed the population of vectors and natural reservoir toward the homes in the Heleia neighborhood creating conditions for this outbreak.

    Full Text Available AIM: Water temperature plays an important role in ecological functioning and in controlling the biogeochemical processes of the aquatic system. Conventional water quality monitoring is expensive and time consuming. It is particularly challenging for large water bodies. Conversely, remote sensing can be considered a powerful tool to assess important properties of aquatic systems because it provides synoptic and frequent data acquisition over large areas. The objective of this study was to analyze time series of surface water temperature and heat flux to advance the understanding of temporal variations in a hydroelectric reservoir. METHOD: MODIS water-surface temperature (WST level 2, 1 km nominal resolution data (MOD11L2, version 5 were used. All available clear-sky MODIS/Terra images from 2003 to 2008 were used, resulting in a total of 786 daytime and 473 nighttime images. Time series of surface water temperature was obtained computing the monthly mean in a 3×3 window of three reservoir selected sites: 1 near the dam, 2 at the centre of the reservoir and 3 in the confluence of the rivers. In-situ meteorological data from 2003 to 2008 were used to calculate surface energy budget time series. Cross-wavelet, coherence and phase analysis were carried out to compute the correlation between daytime and nighttime surface water temperatures and the computed heat fluxes. RESULTS: The monthly mean of the day-time WST shows lager variability than the night-time WST. All time series (daytime and nighttime have a cyclical pattern, passing for a minimum (June - July and a maximum (December and January. Fourier and the Wavelet Analysis were applied to analyze this cyclical pattern. The daytime time series, presents peaks in 4.5, 6 12 and 36 months and the nighttime WST shows the highest spectral density at 12, 6, 3 and 2 months. The multiple regression analysis shows that for daytime WST, the heat flux terms explain 89% of the annual variation (RMS = 0.89

Coletas trimestrais foram realizadas no reservatório durante um ano. As amostras perifíticas foram obtidas pela remoção do biofilme aderido a caules da macrófita Polygonum sp. e a lâminas de vidro. Estas foram colocadas em complexos de madeira e deixadas submersas durante 30 dias para colonização. O estudo taxonômico resultou na identificação de 11 citações pioneiras para o estado do Paraná entre as 96 espécies de diatomáceas determinadas. Maior diversidade de espécies foi registrada para o substrato macrófita. Achnanthidium minutissimum foi dominante na maior parte das amostras analisadas, sendo considerada tolerante às condições eutróficas do reservatório do Iraí. Fragilaria rumpens, Fragilaria vaucheriae var. capitellata e Gomphonema gracile foram abundantes. Informações ecológicas sobre as espécies foram obtidas em literatura, sendo 35% características de sistemas aquáticos em processo avançado de eutrofização, 18% de ambientes mesotróficos e 19% classificadas como tolerantes e indiferentes ao estado trófico dos ambientes.This floristic survey contributed to our knowledge of periphytic diatoms in a eutrophic reservoir in Paraná state, and provided a basis for future works using diatoms as bioindicators of trophic water conditions.

  20. Nuclear waste reform among first energy bills

    International Nuclear Information System (INIS)

    Over 300 bills were introduced in the first week of the new Congress that convened in January, among them a bill aimed at correcting the government's seriously flawed nuclear waste storage program. The bill would required the Department of Energy (DOE) to provide an interim storage site for high-level radioactive waste and spent nuclear fuel at Yucca Mountain, Nevada no later than January 31, 1998. DOE says it will no be able to complete a permanent repository until 2010, and is not obligated to take possession on nuclear waste until a permanent repository is completed. The ever worsening problem prompted 14 utilities and 20 states to file separate lawsuits against the DOE to force the agency into accepting spent fuel. Utilities and ultimately consumers have paid over $8 billion into the Nuclear Waste Fund that is supposed to be used for a permanent repository, but the money has not been put to use yet. Spokesmen for the Nuclear Energy Institute and electric utilities feel that the bill is a step in the right direction and will begin the much needed reforms in the nuclear waste program. Other energy related bills in the 104th Congress are also discussed including the phasing out of funding for the Tennessee Valley Authority

The Electricity Bill also requires producers of fossil-fuelled electricity to charge a compulsory levy which will be used to finance the non-fossil quota. The extra cost of generating electricity by nuclear means compared with the alternatives will be recouped via the 'levy' after the new PWRs have come into operation. Producers of power which is neither nuclear nor fossil will not be required to make this levy, so renewable energies may gain a small competitive advantage. The financial implications of privatisation have not been fully clarified, especially regarding nuclear power with its associated expenses of radioactive waste disposal and decommissioning. Energy efficiency may be encouraged by the Bill, but competition may not result from the Bill. (author)

  2. Failed delivery and daily Treasury bill returns

    OpenAIRE

    1990-01-01

    If the seller of a Treasury bill does not provide timely and correct delivery instructions to the clearing bank, the bank does not deliver the security. Further, the seller is not paid until this "failed delivery" is rectified. Since the purchase price is not changed, these "fails" generate interest-free loans from the seller to the buyer. ; This paper studies the effect of failed delivery on Treasury-bill prices. We find that investors bid prices to a premium to reflect the possibility of ob...

    Full Text Available OBJECTIVES: This study aimed to verify the influence of net-cage fish farming on zooplankton biomass in the Itá reservoir (Uruguay River, Brazil. METHODS: Samples were collected monthly from October/2009 to May/2010 at the surface and at the bottom in two sampling stations, the net-cage area and in a control area using a Van Dorn bottle and a plankton net (68 µm. RESULTS: The Cladocera and Copepoda biomass was estimated by dry weight using a micro-analytical balance, and the Rotifera biomass by Biovolume. Total zooplankton biomass varied between 6.47 and 131.56 mgDW.m-3 Calanoida copepod presented the highest value of biomass (127.56 mgDW.m-3 and rotifers, despite having an important contribution to total density, showed a maximum biomass of 2.01 mgDW.m-3. Zooplankton biomass at the net-cage area surface was higher when compared with the control area during the months of October to January. However, the zooplankton biomass was similar at the bottom of the two areas throughout the studied period. From February until May, zooplankton biomass decreased in both sampling stations, a fact probably associated with the flushing of the reservoir, followed by an increase in water transparency and a decrease in chlorophyll-a concentration in the following months (February to May. CONCLUSIONS: The influence of fish farming on zooplankton biomass was detected at the surface of the net-cage area only from October to January. From February to May this influence was not found, probably by the influence of the flushing of the reservoir.OBJETIVO: Este estudo teve o objetivo de verificar a influencia da piscicultura em tanque-rede sobre a biomassa da comunidade zooplanctônica no reservatório de Itá (Rio Uruguai, Brasil.

    Full Text Available Abstract Aim: This paper describes some limnological variables of four reservoirs with different trophic status (Billings, Guarapiranga, Jundiaí and Paiva Castro of the Metropolitan Region of São Paulo, Brazil, aiming to characterize the water quality in these reservoirs. Methods Water sampling occurred between October 2011 and September 2012, on subsurface, at the pelagic compartment. Physical and chemical characteristics of water were evaluated, and the Trophic State Index (TSI was calculated. Multivariate Principal Components Analysis (PCA was used to ordinate sampling sites and periods in relation to environmental data. Results Two reservoirs were classified as eutrophic (Billings and Guarapiranga, one as mesotrophic (Jundiaí and one as oligotrophic (Paiva Castro. The highest concentrations of total phosphorus, nitrogen and chlorophyll a were recorded in the eutrophic reservoirs. The lowest values of dissolved oxygen concentration were registered at Guarapiranga reservoir. Residence time in Paiva Castro reservoir was very low (one day; on the other hand, the highest value was recorded in Billings reservoir: 428 days.

    Full Text Available OBJETIVO: Um dos maiores danos causados pela oclusão em bombas de rolete é a hemólise. Estudos comparativos entre bomba de roletes com ajustes não oclusivos e bombas centrífugas têm sido realizados nas últimas décadas na tentativa de desenvolver novos produtos e ajustes que causem menos trauma aos elementos figurados do sangue. Comumente as bombas de rolete são ajustadas pelo método estático devido à preocupação com fluxos variáveis que podem ocorrer com ajustes não oclusivos. Folga excessiva nos roletes permite refluxo e pode acarretar erros no cálculo dos fluxos pela rotação da bomba, de acordo com os dispositivos adicionados ao circuito e a resistência sistêmica do paciente. O objetivo desse trabalho é avaliar o refluxo causado por dois modelos de bombas de rolete em aspirador de sangue e em reservatório de cardiotomia. MÉTODOS: A visualização do refluxo foi realizada em aspirador de sangue e, em reservatório de cardiotomia, a visualização foi acompanhada de respectiva medida. Foram testados dois modelos de bombas de rolete de diferentes fabricantes, ajustadas pelo método de velocidade de queda e calibração dinâmica. Os testes foram conduzidos com tubos de silicone de 3/8 x 1/16 e 1/2 x 3/32 polegadas de diâmetro em água e solução análoga ao sangue. RESULTADOS: Foram registrados visualmente os refluxos em aspirador de sangue e em reservatório de cardiotomia, com respectiva medida dos valores.

    International Nuclear Information System (INIS)

    Pursuant to a judgement passed by the Lower Court of Hamburg, the author discusses probable legal arguments justifying the refusal to pay one's electricity bill, the so-called electricity bill boycott. Following an analysis of the power supply contract and of the content and the limits of the fundamental right of freedom of conscience, as well as of the concept of free enterprise and of the legal effect of licenses under the nuclear law, his point of view stated in the article is to agree with the decision of the court saying that the operation of a nuclear power plant licensed under the nuclear law does not mean an infringement of the right of freedom of conscience. It can further not be accepted to let people refuse to pay their electricity bill by referring to the right of freedom of speech, by alleging conduct against public policy on the part of the public utilities, or by referring to the right of opposition.

Although the Roman Catholic Church has announced its intentions to oppose any liberalization of the abortion law, there are divisions within the Church as evidenced by the existence of groups such as Catholics for a Free Choice. Both senators agree that decriminalization of abortion will depend upon the societal response and an effort must be made to reach the many people who are confused and undecided about the issue. Although the present debate fits within the broader current debate on population policies, it has been the insistence of the feminist movement that put abortion reform on the agenda. Blay's bill calls for the legalization of abortion on demand until the 12th week of pregnancy and in cases of rape or risk to the woman's life after that point. A controversial aspect of Feghall's bill is the inclusion of maternal human immunodeficiency virus (HIV) infection as a condition for abortion. Feghall notes that this is an option rather than a requirement, but she will eliminate this condition if it engenders discrimination against HIV-infected women. PMID:12318722

    Full Text Available The Plachimada Coca-Cola Victims Relief and Compensation Claims Special Tribunal Bill, 2011 was passed by the Kerala Legislative Assembly on 24 February 2011. The Bill provides for the establishment of a special tribunal to settle disputes between the local residents and the Hindustan Coca Cola Company in Plachimada for recovery of compensation for damages caused to individuals, property and the environment by the company. The Bill is reserved for the assent of the President of India. In the meantime, the central government has sought clarifications on the Kerala government’s competence under the Constitution to adopt the Bill. The major issue is the perceived inconsistency between the Bill and some of the central environmental laws. Thus, the constitutional validity of the Bill is in doubt. In this background, this paper examines the issue of legislative competence of the Kerala government to adopt the Bill.

    Full Text Available With the purpose of analyzing the horizontal distribution of the zooplankton community of the Tucuruí Reservoir in the State of Pará, Brazil, collections were made at 16 stations during August 1988. The stations cover the regions called Caraipé (C, Araçagi (B and Ararão (A, and represent the different compartments of this ecosystem in regard to the morphometry and the presence or absence of "flooded forest". Our findings showed the existence of three compartments with different limnological characteristics determined as a function of the system's morphometry, a factor that may have influenced the horizontal circulation of the reservoir's water and, consequently, led to physical, chemical and biological differences at each of the sampled stations. All the stations presented physical and chemical stratification and layers of total anoxia or reduced concentrations of oxygen dissolved at depths corresponding to the limit of the euphotic zone. With regard to the zooplankton, a differentiated distribution that was mainly quantitative was found among the compartments (density of organisms and proportion among the species in the case of Cladocera and Copepoda, and basically qualitative in the case of Rotifera. On the other hand, the greatest densities of organisms for all the groups were recorded at the Caraipé stations. As for the spatial distribution, some species were more restricted or more abundant at given stations. Among the Cladocera, there was a greater abundance of Moina minuta, Bosmina hagmani and Bosminopsis deitersi at the Araçagi stations, while C. cornuta intermedia, C. cornuta rigaudi and C. cornuta cornuta were more plentiful in the Caraipé and Diaphanosoma birgei in the Ararão. Among the Rotifera, Trochosphaera aequatoriales and Lecane proiecta, Ascomorpha ecaudis, besides Polyartha cf vulgaris were restricted, respectively, to the Caraipé, Araçagi and Ararão stations, while the others, such as Keratella americana and

    A 2008 study focused on four key performance indicators (KPIs) and staffing levels to benchmark the FYO7 performance of physician group billing operations. A comparison of the change in the KPIs from FYO3 to FYO7 for a number of these billing operations disclosed across-the-board improvements. Billing operations did not show significant changes in staffing levels during this time, pointing to the existence of obstacles that prevent staff reductions in this area. PMID:18683420

    This paper reports that the House of Representatives has approved a plan to limit U.S. gas prorationing by the states but rejected a move to require petroleum refiners and importers to place 1% of their oil or products volumes into the Strategic Petroleum Reserve. The oil industry lobbied heavily against the SPR provision, which went down 263-135. The House then passed its omnibus energy bill 381-37. It is designed to facilitate all types of energy production while promoting conservation. The legislation also imposes bans on offshore leasing but gives independent producers limited relief from the alternative minimum tax (AMT) and does not include a mandate for use of ethanol in gasoline

Foram selecionados dezoito pontos de amostragem, englobando áreas rasas e áreas profundas. As coletas foram feitas em intervalos trimestrais ao longo de um ano; também foram analisadas as variáveis físicas e químicas da água (nível, transparência, temperatura, oxigênio dissolvido, pH e condutividade elétrica. Amostras do sedimento, para análise da fauna e de fatores abióticos (granulometria e conteúdo orgânico, foram recolhidas em tréplicas, utilizando como coletor a draga de Petersen. O material foi triado e analisado sob microscópio estereoscópico. Contagem e identificação dos organismos foram realizadas, e densidade, abundância relativa, riqueza taxonômica e índice de dominância foram calculados. A análise revelou uma fauna com baixa diversidade e a dominância de Chironomidae e Ephemeroptera. Domínio de Ephemeroptera, constituído por Campsurus, ocorreu no período mais quente do ano e com baixa profundidade da lagoa. A distribuição dos organismos teve como principais fatores determinantes profundidade, transparência, pH e temperatura da água.

    In this work the results of the limnological study of the two reservoirs of the basin of Majaceite river is presented: Guadalcacin and Hurones. These reservoirs are part of the hydrography net of the county of Cadiz (south of Spain) and it belongs to the Guadalquivir Hydrography Confederation. The study of physical chemical parameters, together with the data of the climate variations have allowed to know the quality of the dammed water, as well as, to predict certain behaviour rules in the adaptation of the water, in the drinking waters treatment plant for their final destination as water of supply.

    Full Text Available AIM: This study intends to provide information on how precipitation variation may impact environmental parameters (total phosphorus, water temperature, pH, conductivity, dissolved oxygen, Secchi depth, chlorophyll a and Anabaena abundance and crustacean zooplankton composition and abundance. METHODS: Samples were collected monthly from October 2000 to September 2002 and from October 2007 to September 2009 at one single sampling station located at the deepest point of the reservoir. All data were obtained in the euphotic zone. RESULTS: The highest values of total phosphorous concentrations were reported together with the maximal values of precipitation. Conversely, conductivity decreased during the wet periods. Anabaena presence was only detected between September and December 2001. Daphnia longispina total abundance showed large inter-annual differences. A clear seasonal pattern was inferred for Diaphanosoma brachyurum and Ceriodaphnia pulchella. Both species are thermophilic and begin to be detected in early summer when the water temperature is around 15 ºC. Copidodiaptomus numidicus abundance did not present a clear seasonal pattern. CONCLUSIONS: Some of the observed shifts in environmental parameters (Conductivity, total phosphorus concentrations and Anabaena abundance resulting in changes in zooplankton abundance are induced by rainfall variation. The most affected species were those with a lack of seasonality (C. numidicus or species occurring mainly in winter/early summer (Daphnia longispina. However, a wide range of physical, chemical and biotic interactions is likely to influence zooplankton abundance. Therefore, caution is advised when relating the observed variation exclusively with rainfall intensity. In fact, some of the observed shifts were induced by other factors varying subtly in a seasonal or inter-annual pattern, independently of rainfall intensity.OBJECTIVO: Com o presente estudo pretende-se obter informação sobre os

    Full Text Available Este trabalho propõe uma nova forma de estruturação da lista de materiais, para empresas fabricantes de bens de capital, apesar dos conceitos gerais serem passíveis de utilização em outros tipos de companhias de manufatura. A lista de materiais, como elemento fomentador da integração, é modelada com base em necessidades-chave de diversos usuários, desde o orçamento até a expedição. O objetivo é facilitar as atividades de administração de materiais e gestão da produção. A metodologia desenvolvida consiste em estruturar uma lista de materiais paralela, delineada em função do organograma fabril da empresa e da seqüência de fabricação do produto no tempo. Esses conceitos foram aplicados na formação de grupos de dispositivos dedicados, utilizados na fabricação de hidrogeradores, na SADE VIGESA S/A., fábrica de Araraquara.This paper suggests a new idea to form a Bill of Materials (BOM, for heavy equipment manufacturing companies, with the general concepts applied in others kind of manufacturing companies. The bill of materials, as an essential element of integration, from marketing to delivery, aims to facilitate the activities of Production Planning and of the Control System. The methodology developed is based on a new approach to build parallel bill of materials, using concepts of pseudo levels and assemblies, mainly based on the industrial organizational structure of the company and on the sequence of product fabrication in time. The implementation of this system for dedicated fixtures resulted in expressive reduction of lead time, project hours, fabrication hours and costs.

  2. Sediment management for reservoir

    International Nuclear Information System (INIS)

    All natural lakes and reservoirs whether on rivers, tributaries or off channel storages are doomed to be sited up. Pakistan has two major reservoirs of Tarbela and Managla and shallow lake created by Chashma Barrage. Tarbela and Mangla Lakes are losing their capacities ever since first impounding, Tarbela since 1974 and Mangla since 1967. Tarbela Reservoir receives average annual flow of about 62 MAF and sediment deposits of 0.11 MAF whereas Mangla gets about 23 MAF of average annual flows and is losing its storage at the rate of average 34,000 MAF annually. The loss of storage is a great concern and studies for Tarbela were carried out by TAMS and Wallingford to sustain its capacity whereas no study has been done for Mangla as yet except as part of study for Raised Mangla, which is only desk work. Delta of Tarbala reservoir has advanced to about 6.59 miles (Pivot Point) from power intakes. In case of liquefaction of delta by tremor as low as 0.12g peak ground acceleration the power tunnels I, 2 and 3 will be blocked. Minimum Pool of reservoir is being raised so as to check the advance of delta. Mangla delta will follow the trend of Tarbela. Tarbela has vast amount of data as reservoir is surveyed every year, whereas Mangla Reservoir survey was done at five-year interval, which has now been proposed .to be reduced to three-year interval. In addition suspended sediment sampling of inflow streams is being done by Surface Water Hydrology Project of WAPDA as also some bed load sampling. The problem of Chasma Reservoir has also been highlighted, as it is being indiscriminately being filled up and drawdown several times a year without regard to its reaction to this treatment. The Sediment Management of these reservoirs is essential and the paper discusses pros and cons of various alternatives. (author)

    Full Text Available The aim of this study was to determine morphological patterns of the most abundant fish species found in reservoirs with different hydraulic retention times and stages of colonization, considering habitat strata and feeding strategies. Samplings were carried out in six Paraná State (Brazil reservoirs, and morphological data were obtained from 15 individuals of 17 fish species. Ecomorphological attributes that best segregated species, were selected using Discriminant Analysis. These selected attributes were later used in a Principal Components Analysis (PCA. Differences among reservoirs concerning occupation of the ecomorphological space were tested through analysis of variance (null models. The six reservoirs differed in the occupation of the fish species ecomorphological space and the first two PCA axes explained 66,3% of the total data variability. Thus alterations in water dynamics could a major factor affecting patterns of fish distribution in reservoirs.Neste estudo, são analisados as restrições na ocupação de peixes em reservatórios com diferentes tempos de retenção da água e estágios de colonização de acordo com características morfológicas das espécies. Busca-se padrões morfológicos mais adaptados na ocupação dos reservatórios considerando diferentes habitats e estratégias alimentares. Os dados morfológicos foram obtidos em 10 indivíduos das espécies mais abundantes em seis reservatórios do estado do Paraná. Os atributos ecomorfológicos que melhor segregaram as espécies foram determinados através de uma Análise Discriminante, sendo estes posteriormente utilizados em uma Análise de Componentes Principais (PCA. Diferenças entre os reservatórios na ocupação do espaço ecomorfológico foram testados através de Análise de Variância (modelo nulo.

    This final report summarizes the progress during the three years of a project on Reservoir Characterization of Pennsylvanian Sandstone Reservoirs. The report is divided into three sections: (i) reservoir description; (ii) scale-up procedures; (iii) outcrop investigation. The first section describes the methods by which a reservoir can be described in three dimensions. The next step in reservoir description is to scale up reservoir properties for flow simulation. The second section addresses the issue of scale-up of reservoir properties once the spatial descriptions of properties are created. The last section describes the investigation of an outcrop.

  6. National uranium resource evaluation: Billings Quadrangle, Montana

    International Nuclear Information System (INIS)

    Five environments in the Billings Quadrangle are favorable for the occurrence of uranium deposits that could contain at least 100 tons U3O8 in rocks that have an average grade of not less than 100 ppM U3O8. The Mississippian Madison Limestone of the Pryor Mountains, a favorable environment for limestone-type deposits, contains a small mining district that has produced over 110,000 pounds of U3O8. The Cambrian Flathead Sandstone along the eastern flanks of the Beartooth Mountains is favorable for unconformity-related deposits; the area contains several uranium occurrences. The Pennsylvanian Tensleep Sandstone along the southern flanks of the Pryor Mountains is a favorable environment for Texas roll-type deposits because of lithology, structure, depositional environment, and proximity to a potential source area. The Cretaceous Lakota and Virgelle Sandstones exhibit the lithology, permeability, and volume to host sandstone-type uranium deposits. All other environments in the quadrangle are unfavorable or unevaluated

    We show that Treasury bill auction procedures create classes of price-equivalent discount rates for bills with fewer than seventy-two days to maturity. We argue that it is inefficient for market participants to bid at a discount rate that is not the minimum rate in its class. The inefficiency of bidding at a rate other than the minimum is related to a quantity shortfall rather than an unexploited profit opportunity. Auction results for weekly offerings of four-week bills and occasional offeri...

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

  17. Marketer consolidated billing : realizing the value of customer relationships

    International Nuclear Information System (INIS)

    This presentation focused on timely issues regarding marketer consolidated billing (MCB). MCB allows energy marketers to directly bill customers for both gas and electric commodities and distribution services. MCB is mandated by the Ontario Energy Board (OEB) in the electricity sector through the Retail Settlements Task Force and is proposed by the OEB in the Gas Distributor Access Rule. The main topics discussed in this paper were the new relationship under MCB, benefits for customers and challenges for marketers. The major obstacles for a successful MCB model were also proposed. The new MCB approach strengthens the relationship between the marketer and the customer. The MCB will allow both electricity and natural gas customers to choose marketers who bill for both delivery and gas on one bill

    A program called ``Innovative Billing?? has been developed to provide individualized energy information for a mass audience?the entireresidential customer base of an electric or gas utility. Customers receive a graph on the bill that compares that customer?s consumption with othersimilar customers for the same month. The program aims to stimulate customers to make ef?ciency improvements. To group as many as severalmillion customers into small ``comparison groups??, an automated method must be developed drawing solely from the data available to the utility.This paper develops and applies methods to compare the quality of resulting comparison groups.A data base of 114,000 customers from a utility billing system was used to evaluate Innovative Billing comparison groups, comparing fouralternative criteria: house characteristics (?oor area, housing type, and heating fuel); street; meter read route; billing cycle. Also, customers wereinterviewed to see what forms of comparison graphs made most sense and led to fewest errors of interpretation. We ?nd that good qualitycomparison groups result from using street name, meter book, or multiple house characteristics. Other criteria we tested, such as entire cycle, entiremeter book, or single house characteristics such as ?oor area, resulted in poor quality comparison groups. This analysis provides a basis forchoosing comparison groups based on extensive user testing and statistical analysis. The result is a practical set of guidelines that can be used toimplement realistic, inexpensive innovative billing for the entire customer base of an electric or gas utility.

Reservoir data and reserves for all oil and gas pools broken down by unit and non-unit areas was also provided. Natural gas production in 1994 was 7.905 billion cubic metres, setting a new record and exceeding the previous record set in 1993 by about 10.5%. Initial reserves of gas were increased by 9.962 billion cubic metres in 1994, resulting in a net increase of 2.051 billion cubic metres and a remaining established reserves year-end value of 86.748 billion cubic meters. There were 892 new gas well completions in 1994. tabs., figs

    Full Text Available The Cartagena Protocol on Biosafety to the Convention on Biological Diversity is an internationally binding instrument addressing issues of biosafety. Biosafety refers to the need to protect human health and the environment from the possible adverse effects of the products of modern biotechnology. Accordingly all countries to the convention are required to put in place regulatory mechanisms to enhance the safety of biotechnology in the context of the Convention’s overall goal of reducing all potential threats to biological diversity, while taking into account the risks to human health. Therefore each country party to the convention has its own procedures to enact laws to guide the safe use of biotechnology. In Uganda the process involves the drafting of the bill by the first parliamentary counsel, approval by cabinet, first reading at the parliament, committal to the responsible parliamentary sessional committee, tabling of the bill for public hearing, consultations, and final approval. In Uganda, the Committee on Science and Technology is responsible for the Biosafety Bill. In March 2013, the Committee tabled the bill for public hearing and submissions from public institutions. There were comments supporting the passage of the Bill and comments in objection.The reasons for objection are mainly due to precaution, speculation, lack of knowledge about biotechnology and biosafety, and alleged influence from biosafety entrepreneurs. This article reviews these public views, revealing controversy and possible consensus to pass the bill.

    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. PMID:12343938

    Full Text Available The study reports the changes ocurred in feeding ecology of fish species during a tropical river reservoir formation. It was analysed the stomachal contents of 399 individuals belonging to four species of genus Leporinus (L. elongatus Valenciennes, 1849, n=157; L.friderici (Bloch, 1794, n=87; L. octofasciatus Steindachner, 1917, n=107; L.amblyrhynchus Garavello & Britski, 1987, n=48 during formation of Nova Ponte reservoir, State of Minas Gerais, Brazil, in 1993 and 1994. Specimens were separated by sampling period, according with the rate of filling of the reservoir, and standard lenght classes. The species had included in diet vegetal and animal items of autochtone and alochtone origin in several proportions. L. amblyrhynchus fed on basically dipterans in all the sampling periods and length classes. L. elongatus had presented a diverse diet, with predominance of dipterans and vegetal items, and changed the consumed items proportions along the sampling periods and between lenght classes. L. friderici diet was composed mainly by terrestrial insects during the rapid filling period, that were later substituted by fishes and vegetal items. Ontogenetic trophic changes were observed in this species. L. octofasciatus presented a well characterized herbivorous diet, without trophic ontogeny, but with a opportunistic character. Just three pair-species, L. amblyrhynchus-L. elongatus, L. friderici-L. octofasciatus and L. elongatus-L. octofasciatus, have presented some high value of trophic overlap in at least one sampling period. In spite of the fishes of the genus Leporinus being classified like omnivorous in a general way, the differences found between diets of these four species suggest that there is structuration of trophic niches in the reservoir.

  13. Bill (declared urgency) asserting the national commitment for the environment

    International Nuclear Information System (INIS)

    The bill asserting the French national commitment for the environment (also named 'Grenelle 2') is considered as the juridical tool-box of the French environmental policy. It confirms, strengthens, and concretizes the objectives defined by the Grenelle 1 law. The main dispositions of the bill concern the following domains: settlement and urbanism with the improvement of the energy efficiency, energy conservation and life-cycle of buildings; transports with the development of sustainable transportation systems; energy with the creation of regional climate, air and energy schemes with the aim of developing renewable energies (with some restrictions concerning wind power) and reducing CO2 emissions; biodiversity with the creation of ecological pathways between protected areas for the migration of flora and fauna species; environment and waste management with the reinforcement of measures for the abatement of environmental pollutant effects. Among the numerous dispositions involving more than 20 codes (urbanism, environment, buildings etc..) one concerns the progressive implementation of a 'carbon price' index taking into account the greenhouse gas emission costs during the whole life cycle of a product, another one concerns the monitoring of indoor air quality in public buildings. This document is made of three parts. Part 1 is the exposition of the intentions of each article of the bill, part 2 is the bill itself and part 3 is the impact study of the bill in terms of economical, social and environmental impact.

New services especially focused on a mobile telecommunications that would be used not only as a communication de vice but also as a personal gateway to order or consume a variety of services and products [1]. This type of advanced services can be accomplished when the adaptability of the packet-networks (Internet) and the quality of service of the circuit switched networks are combined into one network [2]. New challenges appear in the billing of this heterogeneous multi services network. Some examples of such a services and possible solutions about charging and billing are examined in this paper. The first steps of mathematical model for billing are also considered.

  16. Hospital billing for blood processing and transfusion for inpatient stays.

    Science.gov (United States)

    McCue, Michael J; Nayar, Preethy

    2009-07-01

    Medicare, an important payer for hospitals, reimburses hospitals for inpatient stays using Diagnosis Related Groups (DRGs). Many private insurers also use the DRG methodology to reimburse hospitals for their services. Therefore, those blood service organizations that bill Medicare directly require an understanding of the DRG system of payment to enable them to bill Medicare correctly, and in order to be certain they are adequately reimbursed. Blood centers that do not bill Medicare directly need to understand how hospitals are reimbursed for blood and blood components as this affects a hospital's ability to pay service fees related to these products. This review presents a detailed explanation of how hospitals are reimbursed by the Centers for Medicare and Medicaid Services (CMS) for Medicare inpatient services, including blood services.

We review the enforceable standards of the American Psychological Association's (2002) Ethics Code that deal with advertising, fees, billing, and related business matters in psychotherapy. Using a principle-based perspective, we link each of the standards to overarching ethical values and illustrate the concerns with case vignettes.

    Reservoir properties of chalk depend on the primary sediment composition as well as on subsequent diagenesis and tectonic events. Chalks of the North Sea almost exclusively have mudstone or wackestone texture. Microfossils may have retained their porosity where degree of diagenesis is low, or be......, and the best reservoir properties are typically found in mudstone intervals. Chalk mudstones vary a lot though. The best mudstones are purely calcitic, well sorted and may have been redeposited by traction currents. Other mudstones are rich in very fine grained silica, which takes up pore space and...... thus reduces porosity at the same time as it increases specific surface and thus cause permeability to be low.

Blue Ridge Reservoir is a single-purpose hydropower generating project. When consistent with this primary objective, the reservoir is also operated to benefit secondary objectives including water quality, recreation, fish and aquatic habitat, development of shoreline, aesthetic quality, and other public and private uses that support overall regional economic growth and development. 8 refs., 1 fig.

  3. Structural controls on ground-water conditions and estimated aquifer properties near Bill Williams Mountain, Williams, Arizona

    Pierce, Herbert A.

    2001-01-01

    As of 1999, surface water collected and stored in reservoirs is the sole source of municipal water for the city of Williams. During 1996 and 1999, reservoirs reached historically low levels. Understanding the ground-water flow system is critical to managing the ground-water resources in this part of the Coconino Plateau. The nearly 1,000-meter-deep regional aquifer in the Redwall and Muav Limestones, however, makes studying or utilizing the resource difficult. Near-vertical faults and complex geologic structures control the ground-water flow system on the southwest side of the Kaibab Uplift near Williams, Arizona. To address the hydrogeologic complexities in the study area, a suite of techniques, which included aeromagnetic, gravity, square-array resistivity, and audiomagnetotelluric surveys, were applied as part of a regional study near Bill Williams Mountain. Existing well data and interpreted geophysical data were compiled and used to estimate depths to the water table and to prepare a potentiometric map. Geologic characteristics, such as secondary porosity, coefficient of anisotropy, and fracture-strike direction, were calculated at several sites to examine how these characteristics change with depth. The 14-kilometer-wide, seismically active northwestward-trending Cataract Creek and the northeastward-trending Mesa Butte Fault systems intersect near Bill Williams Mountain. Several north-south-trending faults may provide additional block faulting north and west of Bill Williams Mountain. Because of the extensive block faulting and regional folding, the volcanic and sedimentary rocks are tilted toward one or more of these faults. These faults provide near-vertical flow paths to the regional water table. The nearly radial fractures allow water that reaches the regional aquifer to move away from the Bill Williams Mountain area. Depth to the regional aquifer is highly variable and depends on location and local structures. On the basis of interpreted

    Full Text Available AIM: The aim of the present study was to evaluate the diet and biological attributes of the population of Apareiodon affinis residing near net-cage fish farming activities in the Chavantes reservoir. METHODS: Samples were collected from two populations: one near the net cages (NC and one from an area not influenced by these cages denominated the "reference site" (RS. Monthly sampling was carried out from Mar/2008 to Feb/2009. Fish were caught with a standardized effort using gill nets deployed for 14 hours. After all individuals were measured (standard length and weighed (total weight, carcass weight , body weight without gonads. To determine the composition of the diet, the alimentary index was calculated (AI. We also calculated the length-weight relationship, condition factor, gonad-somatic index (GSI and reproductive potential. RESULTS: A total of 3050 individuals were caught. The results of the (AI revealed that the item detritus was the main food used for populations of A. affinis studied in two areas (NC = 73.1% and RS = 95.7%. The use of feed on diet A. affinis was recorded for the populations of NC adding (20.5% of the total items consumed by the population. The resident populations residing near net-cage showed higher condition factor and more reproductive period. CONCLUSIONS: The results show the ability of the species to benefit from the input of organic matter from fish farming activities, inserting a new item in their diet (ration. This work indicates that the species A. affinis managed to establish near net-cage, allocating enough energy to increase their reproductive period and maintain viable populations close to net-cage, evidenced by the high abundance. This study suggests that systems of fish farming in net-cage influence diet and biological attributes of the species A. affinis residents Chavantes reservoir, Brazil.OBJETIVO: O objetivo deste estudo foi avaliar a influência de uma piscicultura em tanques-rede na dieta e nos

  2. Environmental assessment of cooling reservoirs

    International Nuclear Information System (INIS)

    The environmental impacts, both adverse and beneficial, of cooling reservoirs are compared to cooling towers as an alternative closed cycle cooling system. Generally, the impacts associated with the construction of a cooling reservoir system are greater than for a comparable cooling tower system. Operational impacts are generally greater for cooling towers due to their visual impact, plus icing, fogging, and noise problems. The principle advantages of cooling reservoirs are their lower operating and maintenance costs, greater reliability, greater cooling efficiency, reduced water consumption in areas where cooling water storage is required, and their multiple use potential. A review of pertinent literature on cooling reservoir ecosystems, has revealed that entrainment, thermal, and chemical effects generally result in reduced populations of phytoplankton, zooplankton, and benthos in the vicinity of the power plant discharge. Adverse far field effects are generally less significant and are sometimes stimulatory. The overall effects of a power plant on the fish populations of cooling reservoirs appear to be minor. Based on the thermal characteristics of a model 6400 acre cooling reservoir with four 1150 MWe reactors, the ecological characteristics of the reservoir were predicted. The multiple use possibilities of cooling reservoirs provide their most significant beneficial aspect when compared to cooling towers. In addition, the cage culture of food fishes in cooling reservoirs provides an economical and practical method of commercially utilizing the waste heat discharged by power plants. For many areas of the country, cooling reservoirs appear to provide an environmentally and socially desirable alternative to cooling towers

  3. House passes energy bill with one-step plant licensing

    International Nuclear Information System (INIS)

    The US House of Representatives which has traditionally been wary of measures that would allow nuclear power to expand, came down strongly on the side of nuclear when it approved a much-amended omnibus energy bill on May 27 by a vote of 381 to 37. The key for the nuclear industry is the presence in the bill (H.R. 776) of language on one-step power plant licensing that was taken directly from the Senate energy bill (S. 2166) that passed in February. This means that when the House and Senate work out a compromise version of the legislation, one-step licensing is almost certain to be carried through--and become law once the final bill is signed by President George Bush, which is expected later this year. The House's endorsement of nuclear power--both as it exists now, and as it could be with the introduction of new plant designs and an end to the long hiatus in plant orders by utilities--went beyond one-step licensing. Debate on the House floor prior to Memorial Day totally transformed the nuclear-related part of the energy bill. H.R. 776 was reported to the floor by the Rules Committee with language by the Interior and Insular Affairs Committee that would have created a nominal one-step system, with a full evidentiary hearing prior to plant construction but also allowing an intervenor who later presents new information on the plant to get another full evidentiary hearing after construction but before operation. This would effectively duplicate the two-step process that existed for all plants now in service, and which utilities no longer want to endure

    Ramey, H.J. Jr.; Kruger, P.; Miller, F.G.; Horne, R.N.; Brigham, W.E.; Gudmundsson, J.S. (Stanford Geothermal Program)

    1983-12-15

    The attendance at the Workshop was similar to last year's with 123 registered participants of which 22 represented 8 foreign countries. A record number of technical papers (about 60) were submitted for presentation at the Workshop. The Program Committee, therefore, decided to have several parallel sessions to accommodate most of the papers. This format proved unpopular and will not be repeated. Many of the participants felt that the Workshop lost some of its unique qualities by having parallel sessions. The Workshop has always been held near the middle of December during examination week at Stanford. This timing was reviewed in an open discussion at the Workshop. The Program Committee subsequently decided to move the Workshop to January. The Tenth Workshop will be held on January 22-24, 1985. The theme of the Workshop this year was ''field developments worldwide''. The Program Committee addressed this theme by encouraging participants to submit field development papers, and by inviting several international authorities to give presentations at the Workshop. Field developments in at least twelve countries were reported: China, El Salvador, France, Greece, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, the Philippines, and the United States. There were 58 technical presentations at the Workshop, of which 4 were not made available for publication. Several authors submitted papers not presented at the Workshop. However, these are included in the 60 papers of these Proceedings. The introductory address was given by Ron Toms of the U.S. Department of Energy, and the banquet speaker was A1 Cooper of Chevron Resources Company. An important contribution was made to the Workshop by the chairmen of the technical sessions. Other than Stanford Geothermal Program faculty members, they included: Don White (Field Developments), Bill D'Olier (Hydrothermal Systems), Herman Dykstra (Well Testing), Karsten Pruess (Well Testing), John Counsil

  10. Water Management for Competing Uses: Environmental Flows in the Transboundary Rio Grande/Rio Bravo

    Science.gov (United States)

    Sandoval Solis, S.; McKinney, D. C.

    2011-12-01

    Introduction Due to high water demand, the scarcity of water, and the complexity of water allocation, environmental flows have not been considered as an integral part of the water management in the Rio Grande/Rio Bravo transboundary basin. The Big Bend reach is located between the cities of Presidio/Ojinaga to Amistad international reservoir, along the main stream (Fig. 1). Important environmental habitats such as the Big Bend National and State Park in the U.S., the Maderas del Carmen, Cañon de Santa Elena and Ocampo natural reserved areas in Mexico are ecologically threatened because of the lack of environmental water management policies. Several efforts have been undertaken by scientists, government agencies and NGOs to determine the environmental flows for this reach and water management policies that can provide these flows. Objective The objective of this research is to describe a water management policy that can conciliate environmental and human water uses in the Big Bend region. In other words, define a policy that can provide environmental flows without harming water supply for stakeholders or increasing flood risk, within legal and physical constraints of the system. Methodology First, the system was characterized identifying water users, hydraulic infrastructure, and water allocation according to state, federal and international regulations. Second, a hydrograph for environmental flows was proposed that mimics the hydrologic characteristics of the prior dam alteration. Third, a water planning model was constructed to evaluate alternative policies. Fourth, the water management is proposed to provide environmental restoration flows from Luis L. Leon reservoir. This policy considers mechanisms that reduce flooding and drought risks, while meting national and international water regulations. Results Three types of natural flow regimes are considered: (1) median flows aimed to provide the base flow in the region, (2) high flows to provide transversal

  11. Geothermal reservoir management

    Energy Technology Data Exchange (ETDEWEB)

    Scherer, C.R.; Golabi, K.

    1978-02-01

    The optimal management of a hot water geothermal reservoir was considered. The physical system investigated includes a three-dimensional aquifer from which hot water is pumped and circulated through a heat exchanger. Heat removed from the geothermal fluid is transferred to a building complex or other facility for space heating. After passing through the heat exchanger, the (now cooled) geothermal fluid is reinjected into the aquifer. This cools the reservoir at a rate predicted by an expression relating pumping rate, time, and production hole temperature. The economic model proposed in the study maximizes discounted value of energy transferred across the heat exchanger minus the discounted cost of wells, equipment, and pumping energy. The real value of energy is assumed to increase at r percent per year. A major decision variable is the production or pumping rate (which is constant over the project life). Other decision variables in this optimization are production timing, reinjection temperature, and the economic life of the reservoir at the selected pumping rate. Results show that waiting time to production and production life increases as r increases and decreases as the discount rate increases. Production rate decreases as r increases and increases as the discount rate increases. The optimal injection temperature is very close to the temperature of the steam produced on the other side of the heat exchanger, and is virtually independent of r and the discount rate. Sensitivity of the decision variables to geohydrological parameters was also investigated. Initial aquifer temperature and permeability have a major influence on these variables, although aquifer porosity is of less importance. A penalty was considered for production delay after the lease is granted.

  12. Calderas and magma reservoirs

    Science.gov (United States)

    Cashman, Katharine V.; Giordano, Guido

    2014-11-01

    Large caldera-forming eruptions have long been a focus of both petrological and volcanological studies; petrologists have used the eruptive products to probe conditions of magma storage (and thus processes that drive magma evolution), while volcanologists have used them to study the conditions under which large volumes of magma are transported to, and emplaced on, the Earth's surface. Traditionally, both groups have worked on the assumption that eruptible magma is stored within a single long-lived melt body. Over the past decade, however, advances in analytical techniques have provided new views of magma storage regions, many of which provide evidence of multiple melt lenses feeding a single eruption, and/or rapid pre-eruptive assembly of large volumes of melt. These new petrological views of magmatic systems have not yet been fully integrated into volcanological perspectives of caldera-forming eruptions. Here we explore the implications of complex magma reservoir configurations for eruption dynamics and caldera formation. We first examine mafic systems, where stacked-sill models have long been invoked but which rarely produce explosive eruptions. An exception is the 2010 eruption of Eyjafjallajökull volcano, Iceland, where seismic and petrologic data show that multiple sills at different depths fed a multi-phase (explosive and effusive) eruption. Extension of this concept to larger mafic caldera-forming systems suggests a mechanism to explain many of their unusual features, including their protracted explosivity, spatially variable compositions and pronounced intra-eruptive pauses. We then review studies of more common intermediate and silicic caldera-forming systems to examine inferred conditions of magma storage, time scales of melt accumulation, eruption triggers, eruption dynamics and caldera collapse. By compiling data from large and small, and crystal-rich and crystal-poor, events, we compare eruptions that are well explained by simple evacuation of a zoned

    Pneumocystis jirovecii, the fungal agent that causes Pneumocystis pneumonia (PCP), is known to exclusively infect humans. Molecular studies have enabled detection of this fungus in individuals who have been colonized by P. jirovecii. Such colonization, found in several populations, seems to act as a human reservoir for the fungus. Various studies have reported mutations associated with sulfa resistance in P. jirovecii strains isolated from colonized patients, who can transmit the mutant genotype to PCP-susceptible individuals. The growing interest in P. jirovecii colonization may prompt the design of new prevention and management strategies for PCP. PMID:19403207

  16. Moving mountains in Rio

    International Nuclear Information System (INIS)

    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

Tracers complement the more traditional reservoir evaluation tools. This paper discusses the concepts underlying tracer testing, the analysis methods used to produce quantitative results, and the meaning of these results in terms of conceptual picture of the reservoir. Some of the limitations of these analysis methods are discussed, along with ongoing research on tracer flow.

    Reservoir Geochemistry has many important practical applications during petroleum exploration, appraisal and development of oil fields. The most important uses are related to providing or disproving connectivity between reservoirs of a particular well or horizon. During exploration, reservoir geochemistry can indicate the direction of oil filling, suggesting the most appropriate places for drilling new wells. During production, studies of variations in composition with time and determination of proportions of commingled production from multiple zones, may also be carried out. The chemical constituents of petroleum in natural reservoirs frequently show measurable compositional variations, laterally and vertically. Due to the physical and chemical nature of petroleum changes with increasing maturity (or contribution of a second source during the filling process), lateral and vertical compositional variations exist in petroleum columns as reservoir filling is complete. Compositional variation can also be introduced by biodegradation or water washing. Once the reservoir is filled, density driven mixing and molecular diffusion tend to eliminate inherited compositional variations in an attempt to establish mechanical and chemical equilibrium in the petroleum column (England, 1990). Based on organic geochemical analysis it is possible to define these compositional variations among reservoirs, and use these data for developing of petroleum fields and for reservoir appraisal. Reservoir geochemistry offers rapid and low cost evaluation tools to aid in understanding development and production problems. Moreover, the applied methodology is relatively simple and gives reliable results, and can be performed routinely in any good geochemical laboratory at a relatively low cost. (author)

  4. Cointegration and Market Efficiency: An Application to the Canadian Treasury Bill Market.

    OpenAIRE

    Park, S. B.

    1997-01-01

    In this study we examine if the spot and forward interest rates of the Canadian Treasury bill market are cointegrated and test the bill market efficiency. The data used are monthly average yields of three- and six-month Treasury bills from July 1962 to February 1996. Both spot and forward rates are found to be I(0) and cointegrated in the Engle-Granger (1987) sense. Tests based on Hansen=s (1982) GMM method support the bill market efficiency hypothesis.

    had a lower biomass in Brokopondo Reservoir than in Suriname River. Serrasalmus rhombeus showed reduced body length in Brokopondo Reservoir as compared to riverine populations.Foram pesquisadas as modificações a longo prazo na ictiofauna do reservatório de Brokopondo, o primeiro de grande porte (1560 km² construído em floresta tropical úmida. Antes do fechamento da barragem em 1964, a ictiofauna do rio Suriname possuía 172 espécies, com diversidade e equitabilidade altas. A fauna do rio era dominada por espécies de pequeno porte, mas nenhuma delas dominava em número de indivíduos. Em termos de biomassa, os grandes bagres eram dominantes. As espécies estavam homogeneamente distribuídas nos diferentes hábitats: corredeiras, afluentes e canal principal. Quatro anos depois do fechamento da barragem, somente 62 espécies de peixes foram coletadas no reservatório de Brokopondo, mas a composição da ictiofauna ainda estava mudando. Em 1978, a ictiofauna do reservatório era semelhante à de 2005, indicando que um equilíbrio estável foi atingindo 14 anos depois do fechamento da barragem. A ictiofauna do reservatório tinha 41 espécies, diversidade e equitabilitade baixas. A maioria das espécies do rio Suriname que tinham exigências estreitas de hábitat não sobreviveram no reservatório. A estrutura das comunidades de peixes foi diferente nos quatro hábitats do reservatório de Brokopondo. O hábitat das águas abertas (10 espécies foi dominado pelos piscívoros Serrasalmus rhombeus, Acestrorhynchus microlepis e Cichla ocellaris e suas presas Bryconops melanurus e duas espécies de Hemiodus. Bryconops alimentou se de zooplâncton, pupas de Culicidae e invertebrados terrestres. Hemiodus alimentou se de detritos floculentos, demostrando que a cadeia alimentar baseada em detritos ainda era importante em estágios avançados de desenvolvimento dos reservatórios. Serrasalmus rhombeus também come queixadas que se afogam quando tentam atravessar nadando o

  5. Cesium reservoir and interconnective components

    International Nuclear Information System (INIS)

    The program objective is to demonstrate the technology readiness of a TFE (thermionic fuel element) suitable for use as the basic element in a thermionic reactor with electric power output in the 0.5 to 5.0 MW range. A thermionic converter must be supplied with cesium vapor for two reasons. Cesium atoms adsorbed on the surface of the emitter cause a reduction of the emitter work function to permit high current densities without excessive heating of the emitter. The second purpose of the cesium vapor is to provide space-charge neutralization in the emitter-collector gap so that the high current densities may flow across the gap unattenuated. The function of the cesium reservoir is to provide a source of cesium atoms, and to provide a reserve in the event that cesium is lost from the plasma by any mechanism. This can be done with a liquid cesium metal reservoir in which case it is heated to the desired temperature with auxiliary heaters. In a TFE, however, it is desirable to have the reservoir passively heated by the nuclear fuel. In this case, the reservoir must operate at a temperature intermediate between the emitter and the collector, ruling out the use of liquid reservoirs. Integral reservoirs contained within the TFE will produce cesium vapor pressures in the desired range at typical electrode temperatures. The reservoir material that appears to be the best able to meet requirements is graphite. Cesium intercalates easily into graphite, and the cesium pressure is insensitive to loading for a given intercalation stage. The goals of the cesium reservoir test program were to verify the performance of Cs-graphite reservoirs in the temperature-pressure range of interest to TFE operation, and to test the operation of these reservoirs after exposure to a fast neutron fluence corresponding to seven year mission lifetime. In addition, other materials were evaluated for possible use in the integral reservoir

  6. [World deliberations in Rio].

    Annis, B

    1991-01-01

    The United Nations Conference on Environment and Development (UNCED) was held in Rio de Janeiro in June 1992 and dealt with world trade, environmental education, environmental emergencies, the transfer of technology and financial resources, and the restructuring of international systems for tackling environmental problems. Other issues on the agenda were the protection of the atmosphere, the ozone shield, deforestation, the conservation of biological diversity, sustainable urban and rural development, and the safeguarding of human health and quality of life. The preparation for the conference took place through a series of meetings, which also featured the problems of rural areas in the Americas. Some environmental organizations based in Washington, D.C. had become impassive over the years and promoted bipartisan and apolitical issues in order to obtain funds. Nonetheless, some groups criticized the projects of the World Bank. In 1990 the World Bank established the World Environmental Program for developing countries, which envisioned the execution of 15 projects and 11 technical assistance proposals. Nongovernmental organizations (NGOs) were also active in this effort. The Interamerican Development Bank also launched a forest policy for preserving forest resources. This was the consequence of the 1982 scheme that aimed at protecting forest populations and promoting sustainable forest industries. At another conference of development specialists the discrimination against women was cited as a major factor in the deleterious use of natural resources. A new development concept was urged that would incorporate the rights and participation of women as a central strategy in solving the global environmental crisis. The global population is growing at a rate of 95 million people per year, which underlines the need for better representation of women, poor people, and rural areas in state agencies and multilateral and environmental organizations for promoting sustainable

  7. Monthly Anomaly in U.S. Treasury Bills Market

    Directory of Open Access Journals (Sweden)

    Shaikh A. Hamid

    2016-04-01

    Full Text Available We explore monthly anomaly in total monthly returns of U.S. Treasury bills from January 1926 to December 2013. The mean of monthly returns for the entire period as well as the mean of monthly returns of all the months were significantly greater than zero. No monthly seasonality was detected either in terms of mean or variance. When we slice the data into four sub-periods, we find results similar to what we find for the entire data set. The non-existence of significant differences in the means or the volatilities of the returns of a month compared to the other eleven months stacked shows that the T-bills market is largely free from monthly anomalies. This is contrary to what we found with similar studies on monthly returns of long-term Treasury bonds and corporate bonds. The mean of total monthly returns during Republican presidencies was higher than during Democratic presidencies.

  8. Algorithmic acquisition of diagnostic patterns in district heating billing system

    International Nuclear Information System (INIS)

    An application of algorithmic exploration of billing data is examined for fault detection, diagnosis (FDD) based on evaluation of present state and detection of unexpected changes in energy efficiency of buildings. Large data sets from district heating (DH) billing systems are used for construction of feature space, diagnostic rules and classification of the buildings according to their energy efficiency properties. The algorithmic approach automates discovering knowledge about common, thus accepted changes in buildings’ properties, in equipment and in habitants’ behavior reflecting progress in technology and life style. In this article implementation of Data Mining and Knowledge Discovery (DMKD) method in supervision system with exemplary results based on real data is presented. Crucial steps of data processing influencing diagnostic results are described in details.

  9. Science budget bills wind through U.S. Congress

    Showstack, Randy

    With the U.S. economy booming and the science community pushing for across the board increases for federal research and development programs, science budgets are faring well in the House and Senate. When Congress returns to Washington in September following a summer recess, its priorities include finalizing four major, nondefense budget bills that affect science. These bills could provide significant funding increases for fiscal year 1998.How do these number compare to the new balanced budget agreement? According to analysts, the budget for the next fiscal year actually increases, with precipitous cuts delayed for several years. Although the outlook for long-term funding may be grim, science budgets look good for this year.

    Changes in six-month bill rates over semiannual periods in the 1960s and 1970s are successfully related to expected changes and to surprises. The latter include unanticipated changes in expected inflation, in the growth of industrial production and base money, and in inflation uncertainty. Estimation of the basic equation through the middle of 1983 does not suggest anychange in structure. Moreover the equation "explains" 60 percent of the extraordinarily high level of real rates since late 19...

  5. SMS- based Recharge Protocol for Prepaid Energy Billing System

    Directory of Open Access Journals (Sweden)

    B. O. Omijeh

    2012-12-01

    Full Text Available A prepaid energy metering system enables power utilities to collect energy bills from the consumers’ prior to the usage of power by delivering only as much as what has been paid for. In Nigeria, the current prepaid meters use the keypad technology or smart card for their energy re-loading or recharging. This poses some challenges because the consumers have to travel a long distance to the utility company, waste a lot of time and energy before getting his/her energy meter activated when out of energy credit. In this paper, an SMS-recharge system for prepaid meter is proposed whereby consumers at the comfort of their homes, without stress or waste of energy or time, can recharge/activate their meters via SMS without the use of keypad by sending a 12-digit Pin number via SMS to the utility company. The aim of this paper is to model an intelligent billing system and develop an SMS protocol for the recharge scheme. This work contains the methodology and developed SMS protocol-link between the GSM modem (M20 and the Microcontroller (PIC 18F2550 for this process .The entire billing process is designed and simulated in Matlab/Simulink environments. Results obtained are very satisfactory. When fully implemented in Nigeria, revenue generation in the power sector will greatly increase as more sales of energy vouchers will be made.

  6. Reservoir engineering and hydrogeology

    International Nuclear Information System (INIS)

    Summaries are included which show advances in the following areas: fractured porous media, flow in single fractures or networks of fractures, hydrothermal flow, hydromechanical effects, hydrochemical processes, unsaturated-saturated systems, and multiphase multicomponent flows. The main thrust of these efforts is to understand the movement of mass and energy through rocks. This has involved treating fracture rock masses in which the flow phenomena within both the fractures and the matrix must be investigated. Studies also address the complex coupling between aspects of thermal, hydraulic, and mechanical processes associated with a nuclear waste repository in a fractured rock medium. In all these projects, both numerical modeling and simulation, as well as field studies, were employed. In the theoretical area, a basic understanding of multiphase flow, nonisothermal unsaturated behavior, and new numerical methods have been developed. The field work has involved reservoir testing, data analysis, and case histories at a number of geothermal projects

    The four chapters that are described in this report cover a variety of subjects that not only give insight into the understanding of multiphase flow in fractured porous media, but they provide also major contribution towards the understanding of flow processes with in-situ phase formation. In the following, a summary of all the chapters will be provided. Chapter I addresses issues related to water injection in water-wet fractured porous media. There are two parts in this chapter. Part I covers extensive set of measurements for water injection in water-wet fractured porous media. Both single matrix block and multiple matrix blocks tests are covered. There are two major findings from these experiments: (1) co-current imbibition can be more efficient than counter-current imbibition due to lower residual oil saturation and higher oil mobility, and (2) tight fractured porous media can be more efficient than a permeable porous media when subjected to water injection. These findings are directly related to the type of tests one can perform in the laboratory and to decide on the fate of water injection in fractured reservoirs. Part II of Chapter I presents modeling of water injection in water-wet fractured media by modifying the Buckley-Leverett Theory. A major element of the new model is the multiplication of the transfer flux by the fractured saturation with a power of 1/2. This simple model can account for both co-current and counter-current imbibition and computationally it is very efficient. It can be orders of magnitude faster than a conventional dual-porosity model. Part II also presents the results of water injection tests in very tight rocks of some 0.01 md permeability. Oil recovery from water imbibition tests from such at tight rock can be as high as 25 percent. Chapter II discusses solution gas-drive for cold production from heavy-oil reservoirs. The impetus for this work is the study of new gas phase formation from in-situ process which can be significantly

    The UN Conference on Environment and Development (UNCED in Rio de Janeiro has passed and future plans and expectations are forming for the 1994 International Conference on Population and Development. UNCED did not come up with a miracle cure. Some argued that population control should have been included in the agenda; actually the population issue was not ignored entirely, as both the UNCED Secretary-General and chair of the World Commission on Environment and Development population growth affect both economics and environment. Population must be stabilized. The interrelationships between poverty, population, and environment must be recognized in the formulation of policies. A human rights approach with increased educational opportunities for women, increased women's status, and improved public health and family planning is needed. The UNCED principal document, Agenda 21, devoted an entire chapter to the dynamics of population growth and sustainability. The implications of national demographic trends must be assessed and demographic features included in policies and plans. Debating the accomplishments of UNCED is secondary to planning for the 1994 conference and dealing with the issues: family planning (FP) and well-being, women's status, urbanization and migration, and population policies and programs. The delivery of FP information, education, and services must be expedited by all agencies and organizations; there must be universal availability of maternal and child health care. 500 million women are currently in need of FP. Research is needed to improve contraceptive safety, efficiency, and effectiveness. More than 500,000 maternal deaths occur each year; many could be prevented. 15 million births/year are spaced too closely and infant health is jeopardized. Education and employment of women holds the hope for eliminating some of the social and cultural barriers to women's rights. 45 out of 100 people living in cities today are not experiencing upward mobility

  9. Reservoir Systems in Changing Climate

    Climate change may cause more climate variability and further results in more frequent extreme hydrological events which may greatly influence reservoir¡¦s abilities to provide service, such as water supply and flood mitigation, and even danger reservoir¡¦s safety. Some local studies have identified that climate change may cause more flood in wet period and less flow in dry period in Taiwan. To mitigate climate change impacts, more reservoir space, i.e. less storage, may be required to store higher flood in wet periods, while more reservoir storage may be required to supply water for dry periods. The goals to strengthen adaptive capacity of water supply and flood mitigation are conflict under climate change. This study will focus on evaluating the impacts of climate change on reservoir systems. The evaluation procedure includes hydrological models, a reservoir water balance model, and a water supply system dynamics model. The hydrological models are used to simulate reservoir inflows under different climate conditions. Future climate scenarios are derived from several GCMs. Then, the reservoir water balance model is developed to calculate reservoir¡¦s storage and outflows according to the simulated inflows and operational rules. The ability of flood mitigation is also evaluated. At last, those outflows are further input to the system dynamics model to assess whether the goal of water supply can still be met. To mitigate climate change impacts, the implementing adaptation strategies will be suggested with the principles of risk management. Besides, uncertainties of this study will also be analyzed. The Feitsui reservoir system in northern Taiwan is chosen as a case study.

    With rapid growth in energy efficiency and distributed generation, electric utilities are anticipating stagnant or decreasing electricity sales, particularly in the residential sector. Utilities are increasingly considering alternative rates structures that are designed to recover fixed costs from residential solar photovoltaic (PV) customers with low net electricity consumption. Proposed structures have included fixed charge increases, minimum bills, and increasingly, demand rates - for net metered customers and all customers. This study examines the electricity bill implications of various residential rate alternatives for multiple locations within the United States. For the locations analyzed, the results suggest that residential PV customers offset, on average, between 60% and 99% of their annual load. However, roughly 65% of a typical customer's electricity demand is non-coincidental with PV generation, so the typical PV customer is generally highly reliant on the grid for pooling services.

    The project objective was to detail better ways to assess and exploit intelligent oil and gas field information through improved modeling, sensor technology, and process control to increase ultimate recovery of domestic hydrocarbons. To meet this objective we investigated the use of permanent downhole sensors systems (Smart Wells) whose data is fed real-time into computational reservoir models that are integrated with optimized production control systems. The project utilized a three-pronged approach (1) a value of information analysis to address the economic advantages, (2) reservoir simulation modeling and control optimization to prove the capability, and (3) evaluation of new generation sensor packaging to survive the borehole environment for long periods of time. The Value of Information (VOI) decision tree method was developed and used to assess the economic advantage of using the proposed technology; the VOI demonstrated the increased subsurface resolution through additional sensor data. Our findings show that the VOI studies are a practical means of ascertaining the value associated with a technology, in this case application of sensors to production. The procedure acknowledges the uncertainty in predictions but nevertheless assigns monetary value to the predictions. The best aspect of the procedure is that it builds consensus within interdisciplinary teams The reservoir simulation and modeling aspect of the project was developed to show the capability of exploiting sensor information both for reservoir characterization and to optimize control of the production system. Our findings indicate history matching is improved as more information is added to the objective function, clearly indicating that sensor information can help in reducing the uncertainty associated with reservoir characterization. Additional findings and approaches used are described in detail within the report. The next generation sensors aspect of the project evaluated sensors and packaging

  13. TRITIUM RESERVOIR STRUCTURAL PERFORMANCE PREDICTION

    The burst test is used to assess the material performance of tritium reservoirs in the surveillance program in which reservoirs have been in service for extended periods of time. A materials system model and finite element procedure were developed under a Savannah River Site Plant-Directed Research and Development (PDRD) program to predict the structural response under a full range of loading and aged material conditions of the reservoir. The results show that the predicted burst pressure and volume ductility are in good agreement with the actual burst test results for the unexposed units. The material tensile properties used in the calculations were obtained from a curved tensile specimen harvested from a companion reservoir by Electric Discharge Machining (EDM). In the absence of exposed and aged material tensile data, literature data were used for demonstrating the methodology in terms of the helium-3 concentration in the metal and the depth of penetration in the reservoir sidewall. It can be shown that the volume ductility decreases significantly with the presence of tritium and its decay product, helium-3, in the metal, as was observed in the laboratory-controlled burst tests. The model and analytical procedure provides a predictive tool for reservoir structural integrity under aging conditions. It is recommended that benchmark tests and analysis for aged materials be performed. The methodology can be augmented to predict performance for reservoir with flaws.

    1979-11-01

    The Geothermal Reservoir Well Stimulation Project has prepared a two-year program to develop and field test methods of stimulating geothermal wells. The program provides for six field experiments which progress in difficulty from low temperature reservoirs using current technology to high temperature reservoirs using advanced types of stimulation treatments. The process used to select the six field experiment locations and stimulation treatments is described. Tentatively, the following reservoirs are proposed: Raft River, East Mesa, Baca and Westmorland (two experiments), and Brawley and The Geysers or Roosevelt Hot Springs (two experiments). The program will be reviewed after each field treatment to select a specific well candidate for the next experiment and to determine whether alteration of the sequence will be beneficial to the overall success of the project and the geothermal industry.

    We studied the diets of nestling Gull-billed Terns (Sterna nilotica) at colonies in coastal Virginia during the breeding seasons of 1995 and 1996 as part of a long-term study of the species. No previous quantitative assessments had been made of diets of this species anywhere along the Atlantic Coast, and only a few observations had been reported from other coastal areas in the southern United States. During 80 h of observations over the two seasons, 757 feeding observations were made, primarily at two colony sites. We examined how prey type (fish, marine invertebrates, terrestrial prey) and size were influenced by year, tide cycle, season (early and late) and age of the young (small chicks 7 d). We did not find significant year differences, but all other factors revealed statistically significant results. Older (>7 d) chicks were fed relatively more terrestrial and marine invertebrate prey than were younger chicks. In June (early season), fewer fish and terrestrial prey were fed to chicks than later (July-August). Most prey were less than one bill length in size, with the majority of the smallest prey being marine invertebrates. Tide cycle influenced prey delivered with terrestrial prey becoming relatively more important during high and ebb periods than during low and flood tides when aquatic prey dominated. The major marine invertebrate prey taken was the fiddler crab (Uca spp.). Terrestrial prey consisted mostly of large odonates and orthopterans. Unlike earlier reports from Europe, we found no regurgitated food pellets in any of the colonies in either year. This study confirms that the Gull-billed Tern is an extremely opportunistic feeder and has adapted to a variety of habitats, helping to explain its cosmopolitan distribution.

    In this court decision, nuclear opponents who had withheld payment of 10 percent of their electricity bills were condemned to payment of the full amounts of their invoices. The decision thus differs from opposed decisions by the Stuttgart District Court dated July 20, 1979 (ET 1979, p. 495), which had been regarded as 'faulty' by the Federal Constitutional Court (decision of December 20, 1979, ET 1980, p. 135). According to the new decision, the actions brought for performance and for declaratory judgment are admissible and well-founded. In particular, the nuclear opponents have no credible legal reason to withhold or deny performance. (HSCH)

    Introduced a decade ago, reservoir computing is an efficient approach for signal processing. State of the art capabilities have already been demonstrated with both computer simulations and physical implementations. If photonic reservoir computing appears to be promising a solution for ultrafast nontrivial computing, all the implementations presented up to now require digital pre or post processing, which prevents them from exploiting their full potential, in particular in terms of processing speed. We address here the possibility to get rid simultaneously of both digital pre and post processing. The standalone fully analogue reservoir computer resulting from our endeavour is compared to previous experiments and only exhibits rather limited degradation of performances. Our experiment constitutes a proof of concept for standalone physical reservoir computers.

    Full Text Available Water contamination in the semi-arid section of Northeast Brazil is a current concern for the country’s researchers, since this region is considered one of the poorest in Brazil and the water in these locations is a primary vehicle for disease transmission. We collected physical and chemical data as well as water samples from four semiarid potiguar reservoirs during the dry and rainy seasons of 2013 and 2014. These samples were prepared in a laboratory at the Federal University of Rio Grande do Norte (UFRN and their physical, chemical and microbiological characteristics were evaluated. The procedures of microbial isolation and identification followed the Standard Methods for Examinations of Water and Wastewater. Then Vitek II system (Bio-Merieux® was used to identify the microbial specimens and we calculated the frequency of specimens’ occurrence. Altogether, 168 bacteria were isolated and identified; 97% were Gram-negative and only 3% were Gram-positive. Within the Gram negatives, 73.2% were identified as belonging to the Enterobacteriaceae family and, in general terms, the most constant genera in the water reservoirs were Vibrio and Aeromonas. Among the Enterobacteriaceae family, the species Escherichia coli, Enterobacter cloacae complex and Klebsiella pneumoniae were the most frequent. There was no statistical difference between the number or morphotype groups found in the periods, p=0.255 and p=0.237, respectively. The analyzed data indicate possible contamination of these water reservoirs by human and/or animal fecal material.

  15. Chickamauga reservoir embayment study - 1990

    Meinert, D.L.; Butkus, S.R.; McDonough, T.A.

    1992-12-01

    The objectives of this report are three-fold: (1) assess physical, chemical, and biological conditions in the major embayments of Chickamauga Reservoir; (2) compare water quality and biological conditions of embayments with main river locations; and (3) identify any water quality concerns in the study embayments that may warrant further investigation and/or management actions. Embayments are important areas of reservoirs to be considered when assessments are made to support water quality management plans. In general, embayments, because of their smaller size (water surface areas usually less than 1000 acres), shallower morphometry (average depth usually less than 10 feet), and longer detention times (frequently a month or more), exhibit more extreme responses to pollutant loadings and changes in land use than the main river region of the reservoir. Consequently, embayments are often at greater risk of water quality impairments (e.g. nutrient enrichment, filling and siltation, excessive growths of aquatic plants, algal blooms, low dissolved oxygen concentrations, bacteriological contamination, etc.). Much of the secondary beneficial use of reservoirs occurs in embayments (viz. marinas, recreation areas, parks and beaches, residential development, etc.). Typically embayments comprise less than 20 percent of the surface area of a reservoir, but they often receive 50 percent or more of the water-oriented recreational use of the reservoir. This intensive recreational use creates a potential for adverse use impacts if poor water quality and aquatic conditions exist in an embayment.

  16. Capacity sharing of water reservoirs

    Science.gov (United States)

    Dudley, Norman J.; Musgrave, Warren F.

    1988-05-01

    The concept of a water use property right is developed which does not apply to water volumes as such but to a share of the capacity (not contents) of river storage reservoirs and their inflows. The shareholders can withdraw water from their share over time in accordance with their preferences for stability of water deliveries. The reservoir authority does not manage reservoir releases but keeps record of individual shareholder's withdrawals and net inflows to monitor the quantity of water in each shareholder's capacity share. A surplus of total reservoir contents over the sum of the contents of the individual shareholder's capacity shares will accrue over time. Two different criteria for its periodic distribution among shareholders are compared. A previous paper Dudley (this issue(b)) noted a loss of short-run economic efficiency as reservoir and farm management decision making become separated. This is largely overcome by capacity sharing which allows each user to integrate the management of their portion of the reservoir and their farming operations. The nonattenuated nature of the capacity sharing water rights also promotes long-run economic efficiency.

    This annual report describes the progress during the second year of a project on Reservoir Characterization of Pennsylvanian Sandstone Reservoirs. The report is divided into three sections: (i) reservoir description and scale-up procedures; (ii) outcrop investigation; (iii) in-fill drilling potential. The first section describes the methods by which a reservoir can be characterized, can be described in three dimensions, and can be scaled up with respect to its properties, appropriate for simulation purposes. The second section describes the progress on investigation of an outcrop. The outcrop is an analog of Bartlesville Sandstone. We have drilled ten wells behind the outcrop and collected extensive log and core data. The cores have been slabbed, photographed and the several plugs have been taken. In addition, minipermeameter is used to measure permeabilities on the core surface at six inch intervals. The plugs have been analyzed for the permeability and porosity values. The variations in property values will be tied to the geological descriptions as well as the subsurface data collected from the Glen Pool field. The third section discusses the application of geostatistical techniques to infer in-fill well locations. The geostatistical technique used is the simulated annealing technique because of its flexibility. One of the important reservoir data is the production data. Use of production data will allow us to define the reservoir continuities, which may in turn, determine the in-fill well locations. The proposed technique allows us to incorporate some of the production data as constraints in the reservoir descriptions. The technique has been validated by comparing the results with numerical simulations.

    A new 'growing' maximum likelihood classification algorithm for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region, Ghana. The delineation algorithm is able to find the land-water boundary from SAR imagery for different weather and environmental conditions. As such, the algorithm allows for remote sensed operational monitoring of small reservoirs. Multipurpose small reservoirs (1-100 ha) are important for many livelihoods in rural semi-arid West Africa. In order to manage and plan these reservoirs and to assess their hydrological impact at a river basin scale, it is important to monitor their water storage fluctuation. Several studies on remotely sensed reservoir mapping have recently been published, but no single method yields good results for all weather and environmental conditions. Detection of small reservoirs from optical satellite imagery using supervised maximum likelihood classification is a well proved method. The application of this method for the monitoring of small reservoirs is however limited because of its dependence on cloud-free day-acquisitions. Delineation from SAR images is promising, but because of difficulties with wind induced Bragg-scattering and low contrast between the water surface and the dried-out surroundings at the end of the dry season, only quasi manual methods have been applied successfully. A smart combination of optical satellite based detection combined with a delineation method for SAR imagery is proposed. From the optical satellite based small reservoir detection the reservoir window is determined in which the 'growing' maximum likelihood classification on SAR images is performed. A water-class seed and land-class seed are implemented and grown dependent on the likelihood of a pixel to belong to one class. The likelihood is calculated based on the probability distributions of the growing land and water populations. Combinations of single

    Full Text Available O presente trabalho foi realizado com o objetivo de estudar a coleta e o descarte de plantas aquáticas em diferentes locais e infestações do sistema Tietê/Paraná, no reservatório de Jupiá. A operação foi realizada com auxílio de instrumentação instalada em uma colhedora de plantas aquáticas, com sistema de GPS dotado de sinal de correção diferencial. Os tempos gastos para carregar e descarregar a colhedora foram determinados por cronometragem, e a distância do ponto final de coleta ao ponto de descarte e o tempo de deslocamento, por cronometragem e uso de GPS convencional. Em algumas coletas foram demarcados polígonos, instruindo-se o operador a trabalhar exclusivamente na área correspondente. A interpretação dos resultados permitiu determinar a participação do tempo de coleta em relação ao tempo total de operação, indicando um valor significativo do ponto de vista operacional (>70%. Considerando o descarte em áreas infestadas com "taboa", o deslocamento total médio foi de apenas 383 m, com gasto médio de 200,96 s. Os valores de capacidade operacional da colhedora oscilaram entre 0,23 e 1,60 ha h-1, indicando valor médio de 4,48 ha dia-1. A maior limitação à capacidade operacional associou-se à velocidade média de deslocamento, com maior agravante em áreas com altas infestações ou profundas. Considerando-se o deslocamento da colhedora, houve grande dificuldade de orientação em condições normais de operação, inviabilizando a manutenção de espaçamentos uniformes entre as faixas de coleta e sobrepondo as passagens. Conclui-se que a avaliação operacional indicou a impossibilidade de operar a colhedora sem o auxílio de um sistema de navegação que permita orientar a sua movimentação nas áreas de controle.This work aimed to study the harvest and discard of aquatic plants from different places and infestation in the Tiete/Parana River system.

    Optimal conduct of modern-day physician practices involves a thorough understanding and application of the principles of documentation, coding, and billing. Physicians' role in these activities can no longer be secondary. Surgeons practicing critical care must be well versed in these concepts and their effective application to ensure that they are competitive in an increasingly difficult and demanding environment. Health care policies and regulations continue to evolve, mandating constant education of practicing physicians and their staffs and surgical residents who also will have to function in this environment. Close, collaborative relationships between physicians and individuals well versed in the concepts of documentation, coding, and billing are indispensable. Similarly, ongoing educational and review processes (whether internal or consultative from outside sources) not only can decrease the possibility of unfavorable outcomes from audit but also will likely enhance practice efficiency and cash flow. A financially viable practice is certainly a prerequisite for a surgical critical care practice to achieve its primary goal of excellence in patient care. PMID:10897279

  1. Water Label to Improve Water Billing in Spanish Households

    Full Text Available A significant decrease in water consumption has been achieved in recent years thanks to different campaigns run by different institutions in Spain. However, most citizens do not have a very clear idea about whether or not they are efficiently using water. To solve this situation, this paper aims is to develop two water labels in order to improve the current water billing. These water labels evaluate the total water consumption and the domestic hot water consumption. To make the tags, several research studies were tackled for establishing consumer trends and behavior patterns. Furthermore, a survey and data collection were conducted to obtain updated values to validate information obtained from previous studies. The result are two water labels that establish six different levels to graphically show the efficiency, and they also include a comparison with the average consumption by customers of the same province. To ensure that the benefits of this evaluation are available to citizens, its inclusion on the water bill is proposed.

    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

    Full Text Available Construction of hydroelectric dams in tropical regions has been contributing significantly to forest fragmentation. Alterations at edges of forest fragments impact plant communities that suffer increases in tree damage and dead, and decreases in seedling recruitment. This study aimed to test the core-area model in a fragmented landscape caused by construction of a hydroelectric power plant in the Brazilian Amazon. We studied variations in forest structure between the margin and interiors of 17 islands of 8-100 hectares in the Tucuruí dam reservoir, in two plots (30 and >100m from the margin per island. Mean tree density, basal area, seedling density and forest cover did not significantly differ between marginal and interior island plots. Also, no significant differences were found in liana density, dead tree or damage for margin and interior plots. The peculiar topographic conditions associated with the matrix habitat and shapes of the island seem to extend edge effects to the islands' centers independently of the island size, giving the interior similar physical microclimatic conditions as at the edges. We propose a protocol for assessing the ecological impacts of edge effects in fragments of natural habitat surrounded by induced (artificial edges. The protocol involves three steps: (1 identification of focal taxa of particular conservation or management interest, (2 measurement of an "edge function" that describes the response of these taxa to induced edges, and (3 use of a "Core-Area Model" to extrapolate edge function parameters to existing or novel situations.A construção de usinas hidrelétricas em regiões tropicais tem contribuído significativamente para a fragmentação da floresta. As alterações nas bordas de fragmentos florestais causam profundos impactos na comunidade de plantas, tais como, o aumento em de árvores mortas ou danificadas e a diminuição do recrutamento de plântulas.

    The Funil Reservoir (Rio de Janeiro State, Brazil) is an environment degraded by constant discharge of nutrients and pollution coming from the most industrialized region of the country. As a consequence of eutrophication, there are continuous cyanobacteria blooms, which cause acute and chronic toxicity to zooplankton. In this context, Phase I of Toxicity Identification Evaluation (TIE) was performed on Daphnia similis using water and interstitial water from the reservoir, with the aim of identifying classes of compounds responsible for toxicity. The results indicated that water toxicity was due to cyanobacteria resulting from blooms in the reservoir and surfactants. Metals, especially copper, contributed to sediment toxicity. This research is the first attempt to describe the nature of toxicity in this reservoir using this method. PMID:25103213

    2006-01-01

    @@ Great development of reservoir protection technology (RPT) has been achieved since 1996, including oil and gas reservoir protection for exploration wells, reservoir protection during underbalanced drilling, protection of fractured tight sandstone gas reservoir, and reservoir protection while increase production and reconstructing, development and enhanced oil recovery (EOR) etc. It has stepped into a new situation with special features and advantage. These technical advancements marked that China's RTP have realized leaps from porous reservoirs to fractured reservoirs,from conventional medium-to-low permeability reservoirs to unconventional reservoirs, from oil and gas producers to exploration wells, and from application mainly in drilling and completion processes to application in stimulation,development, production and EOR processes.

    Initial drilling of wells on a uniform spacing, without regard to reservoir performance and characterization, must become a process of the past. Such efforts do not optimize reservoir development as they fail to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, and carbonate reservoirs in particular. These reservoirs are typically characterized by: o Large, discontinuous pay intervals o Vertical and lateral changes in reservoir properties o Low reservoir energy o High residual oil saturation o Low recovery efficiency

  9. Cloud computing and Reservoir project

    International Nuclear Information System (INIS)

    The support for complex services delivery is becoming a key point in current internet technology. Current trends in internet applications are characterized by on demand delivery of ever growing amounts of content. The future internet of services will have to deliver content intensive applications to users with quality of service and security guarantees. This paper describes the Reservoir project and the challenge of a reliable and effective delivery of services as utilities in a commercial scenario. It starts by analyzing the needs of a future infrastructure provider and introducing the key concept of a service oriented architecture that combines virtualisation-aware grid with grid-aware virtualisation, while being driven by business service management. This article will then focus on the benefits and the innovations derived from the Reservoir approach. Eventually, a high level view of Reservoir general architecture is illustrated.

    2002-01-01

    We report on recent work to produce a small low power, low cost reservoir cathode capable of long life (more than 100,000 hours) at high loading (> 5 A/sq cm). Our objective is a highly manufacturable, commercial device costing less than $30. Small highly loaded cathodes are needed, especially for millimeter wave tubes, where focusing becomes difficult when area convergence ratios are too high. We currently have 3 models ranging from .060-inch diameter to. 125-inch diameter. Reservoir type barium dispenser cathodes have a demonstrated capability for simultaneous high emission density and long life. Seven reservoir cathodes continue to operate on the cathode life test facility at NSWC, Crane, Indiana at 2 and 4 amps/sq cm. They have accumulated nearly 100,000 hours with practically no change in emission levels or knee temperature.

  11. Providing content based billing architecture over Next Generation Network

    2010-01-01

    Mobile Communication marketplace has stressed that "content is king" ever since the initial footsteps for Next Generation Networks like 3G, 3GPP, IP Multimedia subsystem (IMS) services. However, many carriers and content providers have struggled to drive revenue for content services, primarily due to current limitations of certain types of desirable content offerings, simplistic billing models, and the inability to support flexible pricing, charging and settlement. Unlike wire line carriers, wireless carriers have a limit to the volume of traffic they can carry, bounded by the finite wireless spectrum. Event based services like calling, conferencing etc., only perceive charge per event, while the Content based charging system attracts Mobile Network Operators (MNOs) to maximize service delivery to customer and achieve best ARPU. With the Next Generation Networks, the number of data related services that can be offered, is increased significantly. The wireless carrier will be able to move from offering wireles...

  12. The Electricity Bill and opportunities for the future

    International Nuclear Information System (INIS)

    The Bill is an enabling piece of legislation, and much of the detail is contained within the licenses covering the generators, the new public electricity supply companies or distributors, and the transmission company. In addition, the Regulator, who has yet to be appointed and the Secretary of State have sweeping powers if they choose to use them. This makes comment particularly difficult as much depends on the interpretation placed on the legislation by all parties, and the vigour which is applied in policing it. As can be seen following the privatisation of both Gas and Telecoms, key factors will be the individual appointed to the office of Regulator and the holder of the office of Secretary of State. How they interpret their roles and the legislation over the coming years will be crucial. (Author)

  13. Senate backs ALMR/IFR funding; bill goes to conference

    International Nuclear Information System (INIS)

    When September ended, so did the federal government's fiscal year 1993 - officially. The Department of Energy did not have an appropriation, passed by both Houses of Congress and signed into law by President Bill Clinton, to take it into FY 1994, but as debate wore on in Congress, a joint resolution was passed to keep the DOE functioning through October 15. By that time, it was hoped, both Houses would have worked out a consensus DOE budget in a conference committee. Action in the Senate in late September assured that the Integral Fast Reactor (IFR) program, and the advanced liquid metal reactor (ALMR) technology that the IFR incorporates, would have one last chance to survive

  14. The Assisted Dying Bill and the role of the physician.

    Mullock, Alexandra

    2015-08-01

    This article explores the role of the physician in the Assisted Dying Bill, which is currently progressing through the House of Lords. The Supreme Court decision in Nicklinson and Others has alerted Parliament to the possibility that the current prohibition against assisted suicide may breach Article 8 of the European Convention in relation to the right to choose how to end one's life. In this article, the role of healthcare professionals in the proposed legalisation of physician-assisted suicide is examined, together with consideration of key ethical concerns over who might be permitted to access assisted dying. Whether the proposed law presents an ethically sound alternative to the current prohibition against assisting in suicide is not clear, but Parliament must now respond in order to address human rights issues and the call to legalise medically assisted suicide.

    Belden & Blake and the US DOE will cofund a horizontal well to be drilled in the Clinton Sandstone as part of the DOE`s multi well program titled ``Horizontal Drilling in Shallow Geologic Complex Reservoirs.`` This well will be located in Mahoning County, Ohio in an area which has demonstrated above average Clinton gas production. To the best of our knowledge, this will be the first horizontal well drilled to the Clinton Sand formation in Ohio. Since many of the remaining Clinton Sand drilling sites are of poorer reservoir quality, they may not be developed unless technology such as horizontal drilling can be successfully demonstrated.

  9. Portable XRF and principal component analysis for bill characterization in forensic science

    International Nuclear Information System (INIS)

    Several modern techniques have been applied to prevent counterfeiting of money bills. The objective of this study was to demonstrate the potential of Portable X-ray Fluorescence (PXRF) technique and the multivariate analysis method of Principal Component Analysis (PCA) for classification of bills in order to use it in forensic science. Bills of Dollar, Euro and Real (Brazilian currency) were measured directly at different colored regions, without any previous preparation. Spectra interpretation allowed the identification of Ca, Ti, Fe, Cu, Sr, Y, Zr and Pb. PCA analysis separated the bills in three groups and subgroups among Brazilian currency. In conclusion, the samples were classified according to its origin identifying the elements responsible for differentiation and basic pigment composition. PXRF allied to multivariate discriminate methods is a promising technique for rapid and no destructive identification of false bills in forensic science. - Highlights: • The paper is about a direct method for bills discrimination by EDXRF and principal component analysis. • The bills are analyzed directly, without sample preparation and non destructively. • The results demonstrates that the methodology is feasible and could be applied in forensic science for identification of origin and false banknotes. • The novelty is that portable EDXRF is very fast and efficient for bills characterization

  3. Gun control law (Bill C-17), suicide, and homicide in Canada.

    Science.gov (United States)

    Bridges, F Stephen

    2004-06-01

    Canadian Bill C-17 was implemented in 1991 to restrict the use of firearms, providing a chance to investigate the effect of firearm control laws in the use of firearms for suicide and homicide. Following Lester and Leenaars' comprehensive studies, the present study examined the use of firearms for suicide and homicide during the period prior to the bill and during the period after the passing of Bill C-17 to assess the association of the bill with rates of suicide and homicide by method. Analysis showed a significant decrease after passage of Bill C-17 in the rates of suicides and homicides involving firearms and the percentage of suicides using firearms. The analysis provides support for the position that restricting the availability of firearms as a lethal means of committing suicide and homicide may help reduce the numbers of suicides and homicides.

    Several modern techniques have been applied to prevent counterfeiting of money bills. The objective of this study was to demonstrate the potential of Portable X-ray Fluorescence (PXRF) technique and the multivariate analysis method of Principal Component Analysis (PCA) for classification of bills in order to use it in forensic science. Bills of Dollar, Euro and Real (Brazilian currency) were measured directly at different colored regions, without any previous preparation. Spectra interpretation allowed the identification of Ca, Ti, Fe, Cu, Sr, Y, Zr and Pb. PCA analysis separated the bills in three groups and subgroups among Brazilian currency. In conclusion, the samples were classified according to its origin identifying the elements responsible for differentiation and basic pigment composition. PXRF allied to multivariate discriminate methods is a promising technique for rapid and no destructive identification of false bills in forensic science. PMID:24393811

  5. Nechako Reservoir mathematical modelling studies

    International Nuclear Information System (INIS)

    The addition of 540 MW of hydroelectric generating capacity to the Nechako Reservoir involves the increased diversion of water from the headwaters of the Nechako River in the Fraser River drainage to the Kemano River on the Pacific coast. Approval of the project requires a two level release structure at Kenney Dam at the head of the Nechako Canyon to manage downstream flows and water temperatures to conserve and protect chinook and sockeye populations. Two- and three-dimensional mathematical models were used to evaluate the hydrothermal characteristics of the Nechako Reservoir and to assess the capability of the proposed structure to provide releases necessary to meet downstream objectives. Results of the modelling show that deep water intake temperatures are sensitive to reservoir surface elevation and the deep water intake elevation. Modelling results for maximum release of 200 m3/s show that the deep water intake invert should be located at an elevation of 795 m to ensure water temperature criteria are met. The three dimensional modelling showed that little, if any additional bottom water mixing beyond that indicated by the two dimensional results for a nearby lake is likely to occur as a result of the Kenamo completion project. Extreme condition analysis shows that there exists sufficient volumes of cold water in the Nechako reservoir to ensure that the 10 degree C water release criteria can be met for the required period. 4 refs., 1 fig

    Abstract We study a single two-level atom interacting with a reservoir of modes defined by its reservoir structure function. Within this framework we are able to define a density of entanglement involving a continuum of reservoir modes. The density of entanglement is derived for a system with a single excitation by taking a limit of the global entanglement. Utilizing the density of entanglement we quantify the entanglement between the atom and the modes, and also between the reservoir mode...

  13. Amplitude various angles (AVA) phenomena in thin layer reservoir: Case study of various reservoirs

    International Nuclear Information System (INIS)

    Amplitude various offset is widely used in petroleum exploration as well as in petroleum development field. Generally, phenomenon of amplitude in various angles assumes reservoir’s layer is quite thick. It also means that the wave is assumed as a very high frequency. But, in natural condition, the seismic wave is band limited and has quite low frequency. Therefore, topic about amplitude various angles in thin layer reservoir as well as low frequency assumption is important to be considered. Thin layer reservoir means the thickness of reservoir is about or less than quarter of wavelength. In this paper, I studied about the reflection phenomena in elastic wave which considering interference from thin layer reservoir and transmission wave. I applied Zoeppritz equation for modeling reflected wave of top reservoir, reflected wave of bottom reservoir, and also transmission elastic wave of reservoir. Results show that the phenomena of AVA in thin layer reservoir are frequency dependent. Thin layer reservoir causes interference between reflected wave of top reservoir and reflected wave of bottom reservoir. These phenomena are frequently neglected, however, in real practices. Even though, the impact of inattention in interference phenomena caused by thin layer in AVA may cause inaccurate reservoir characterization. The relation between classes of AVA reservoir and reservoir’s character are different when effect of ones in thin reservoir and ones in thick reservoir are compared. In this paper, I present some AVA phenomena including its cross plot in various thin reservoir types based on some rock physics data of Indonesia

    A Turkish-Austrian Consortium is constructing the hydro power plant Ermenek in Turkey. Client of this project is the Turkish State Hydraulic Works, DSI. The project consists of a double curved arch dam, a large grout curtain, a pressure tunnel, a power house and appurtenant structures. The arch dam is ideally located in a narrow gorge, with a natural width at the base of 20 m and at the crest of 110 m, with an entire dam height of 218 m and a concrete volume of 290 000 m{sup 3}. The concreting works for the dam started on 6{sup th} September 2007 and were finished by 20{sup th} October 2009. As the reservoir has an overall volume of about 4 600 million m{sup 3} the impounding started during the construction. Within a very short time the reservoir level has increased up to 70 m above foundation. The entire dam safety concept is discussed. (orig.)

  20. Analysis of artisanal fisheries in two reservoirs of the upper Paraná River basin (Southeastern Brazil

    Directory of Open Access Journals (Sweden)

    Full Text Available We compared the artisanal fisheries, in terms of catch strategies, productivity, and gross per capita income, at two reservoirs: the Barra Bonita (an eutrophic reservoir with some introduced species, and the Jurumirim (an oligotrophic reservoir, with no introduced species. Published data and structured interviews with fishers were used to evaluate fishing activity, fish biomass, and the financial performance of the fisheries. In the Barra Bonita Reservoir we analysed data from 745 fishing trips, from which 86,691.9 kg of fish were landed, with a mean CPUE of 62.4 kg/fisher-1 day-1. The main type of fish caught was tilapia (71,513.5 kg; CPUE of 51.5 kg/fisher-1 day-1, which constituted 82.5% of the biomass caught. In the Jurumirim Reservoir, we analysed data from 2,401 fishing trips, from which 25,093.6 kg of fish were landed, with a mean CPUE of 10.4 kg/fisher-1 day-1. The main type of fish caught was "traíra" (6,158.6 kg; CPUE of 2.6 kg/fisher-1 day-1, which constituted 24.5% of the biomass caught. Ordination analysis (PCA indicated that there was a difference in composition between the fishing reservoirs and ANCOVA showed that there was a significant difference in fish production between the reservoirs. A Student's t-test showed that fishers in the Barra Bonita Reservoir had a significantly higher gross per capita income than those from the Jurumirim Reservoir. Although the Barra Bonita Reservoir has a higher fish production and the fishers earn a higher gross per capita income, we recommend the Jurumirim Reservoir as a model for artisanal fishery management because fishing activity in this reservoir is viable in the long term and such a model would promote conservation and sustainability. This contrasts with the Barra Bonita Reservoir, in which the fishery is not viable in the long term, due to environmental problems caused by artificial eutrophication and the introduction of alien species. It is also noted that in many countries, management

    The Earth Sciences Division of Lawrence Berkeley Laboratory (LBL) is conducting a reservoir evaluation study of the Ahuachapan geothermal field in El Salvador. This work is being performed in cooperation with the Comision Ejecutiva Hidroelectrica del Rio Lempa (CEL) and the Los Alamos National Laboratory (LANL). This report describes the work done during the first year of the study (FY 1988--89), and includes the (1) development of geological and conceptual models of the field, (2) evaluation of the initial thermodynamic and chemical conditions and their changes during exploitation, (3) evaluation of interference test data and the observed reservoir pressure decline, and (4) the development of a natural state model for the field. The geological model of the field indicates that there are seven (7) major and five (5) minor faults that control the fluid movement in the Ahuachapan area. Some of the faults act as a barrier to flow as indicated by large temperature declines towards the north and west. Other faults act as preferential pathways to flow. The Ahuachapan Andesites provide good horizontal permeability to flow and provide most of the fluids to the wells. The underlying Older Agglomerates also contribute to well production, but considerably less than the Andesites. 84 refs.

  2. The billing process at a teaching hospital specialized in cardiology and pulmonology

    2014-09-01

    Full Text Available The objective of this exploratory study was to describe and map out the billing process in a public tertiary-level university hospital specialized in cardiology and pulmonology. In the period between May and June of 2012, we identified and documented the steps in the process validated by the professionals involved in the hospital bill audit service. We found that during billing pre-analysis, auditors make corrections to justify the billing of procedures and to avoid unwarranted billing and loss of revenue. Mapping out the process allowed us to propose strategies to minimize the time for presenting bills to payment sources. By bringing visibility to this process, which is fundamental for the economic-financial balance of the studied hospital, we bring such knowledge to the public domain. Thus, it is accessible to other health organizations that wish to increment their revenue and reduce divergences between patient charts and the patient’s hospital bill. doi: 10.5216/ree.v16i3.23487.

    Problems paying medical bills have been reported to be associated with increased stress, bankruptcy, and forgone medical care. Using the Behavioral Model for Vulnerable Populations developed by Gelberg et al as a framework, as well as data from the 2010 Ohio Family Health Survey, this study examined the relationships between difficulty paying medical bills and forgone medical and prescription drug care. Logistic regression was used to examine associations between difficulty paying medical bills and predisposing, enabling, need (health status), and health behaviors (forgoing medical care). Difficulty paying medical bills increased the effect of lack of health insurance in predicting forgone medical care and had a conditional effect on the association between education and forgone prescription drug care. Those who had less than a bachelor's degree were more likely to forgo prescription drug care than those with a bachelor's degree, but only if they had difficulty paying medical bills. Difficulty paying medical bills also accounted for the relationships between several population characteristics (eg, age, income, home ownership, health status) in predicting forgone medical and prescription drug care. Policies to cap out-of-pocket medical expenses may mitigate health disparities by addressing the impact of difficulty paying medical bills on forgone care. PMID:25856468

    In the Rio Grande Basin, water is overallocated, demands are growing, and river flows and uses are vulnerable to drought and climate change. Currently, the basin is in the third year of severe drought; irrigation and municipal water diversions have been severely curtailed; extensive diversions threaten endangered species, and reservoir volumes are nearly depleted. A central challenge is development of policies that efficiently and equitably allocate the basin's water resources among competing uses across political and institutional jurisdictions. A basin-wide, nonlinear programming model optimizes resource allocations and water use levels for the upper part of the Rio Grande Basin to test whether institutional adjustments can reduce damages caused by drought. Compared to existing institutions, we find that future drought damages could be reduced by 20 and 33% per year through intracompact and interstate water markets, respectively, that would allow water transfers across water management jurisdictions. Results reveal economic tradeoffs among water uses, regions, and drought control strategies.

    Smart Metering is a concept that allows to collect fine-grained consumption profiles from customers by replacing traditional electricity meters with Smart Meters in customers' households. The recorded consumption profile is the basis for the calculation of time-dependent tariffs but also allows deduction of the inhabitant's personal schedules and habits. The current reporting of such consumption profiles only protects this data from 3rd parties but falls short to protect the customer's privacy from illegitimate abuse by the supplier itself. We propose a privacy-preserving profile reporting protocol that enables billing for time-dependent tariffs without disclosing the actual data of the consumption profile to the supplier. Our approach relies on a zero-knowledge proof based on Pedersen Commitments performed by a plug-in privacy component that is put into the communication link between Smart Meter and supplier's back-end systems and requires no change to Smart Meter hardware and only little change to the softw...

  12. Statfjord field: Development strategy and reservoir management

    International Nuclear Information System (INIS)

    This paper reviews the reservoir performance and management of the Statfjord Field after eight years of production. The reason behind the reservoir development strategies and field experiences are presented. The original development plans have been refined based on field performance through an extensive monitoring program and use of reservoir simulation. The acquired data has improved the geological model and the knowledge of fluid movements in all three reservoirs. This has resulted in a large and complex reservoir simulation model with more than 20,000 grid blocks

  13. DAM IMPACTS ON AND RESTORATION OF AN ALLUVIAL RIVER - RIO GRANDE, NEW MEXICO

    The impact of construction of dams and reservoirs on alluvial rivers extends both upstream and downstream of the dam. Downstream of dams, both the water and sediment supplies can be altered leading to adjustments in the river channel geometry and ensuing changes in riparian and aquatic habitats.The wealth of pre and post-regulation data on the Middle Rio Grande, New Mexico, provides an excellent case study of river regulation, channel adjustments, and restoration efforts. Cochiti Dam was constructed on the main stem of the Rio Grande in 1973 for flood control and sediment retention. Prior to dam construction, the Rio Grande was a wide, sandy braided river. Following dam construction, the downstream channel bed degraded and coarsened to gravel size, and the planform shifted to a more meandering pattern. Ecological implications of the geomorphic changes include detachment of the river from the floodplain, reduced recruitment of riparian cottonwoods, encroachment of non-native saltcedar and Russian olive into the floodplain, and degraded aquatic habitat for the Rio Grande silvery minnow.Recent restoration strategies include removal of non-native riparian vegetation, mechanical lowering of floodplain areas, and channel widening.

  14. The role of reservoir characterization in the reservoir management process (as reflected in the Department of Energy`s reservoir management demonstration program)

    Optimum reservoir recovery and profitability result from guidance of reservoir practices provided by an effective reservoir management plan. Success in developing the best, most appropriate reservoir management plan requires knowledge and consideration of (1) the reservoir system including rocks, and rock-fluid interactions (i.e., a characterization of the reservoir) as well as wellbores and associated equipment and surface facilities; (2) the technologies available to describe, analyze, and exploit the reservoir; and (3) the business environment under which the plan will be developed and implemented. Reservoir characterization is the essential to gain needed knowledge of the reservoir for reservoir management plan building. Reservoir characterization efforts can be appropriately scaled by considering the reservoir management context under which the plan is being built. Reservoir management plans de-optimize with time as technology and the business environment change or as new reservoir information indicates the reservoir characterization models on which the current plan is based are inadequate. BDM-Oklahoma and the Department of Energy have implemented a program of reservoir management demonstrations to encourage operators with limited resources and experience to learn, implement, and disperse sound reservoir management techniques through cooperative research and development projects whose objectives are to develop reservoir management plans. In each of the three projects currently underway, careful attention to reservoir management context assures a reservoir characterization approach that is sufficient, but not in excess of what is necessary, to devise and implement an effective reservoir management plan.

    Background The financial success of academic medical centers depends largely on appropriate billing for resident-patient encounters. Objectives of this study were to develop an instrument for billing in internal medicine resident clinics, to compare billing practices among junior versus senior residents, and to estimate financial losses from inappropriate resident billing. Methods For this analysis, we randomly selected 100 patient visit notes from a resident outpatient practice. Three coding specialists used an instrument structured on Medicare billing standards to determine appropriate codes, and interrater reliability was assessed. Billing codes were converted to US dollars based on the national Medicare reimbursement list. Inappropriate billing, based on comparisons with coding specialists, was then determined for residents across years of training. Results Interrater reliability of Current Procedural Terminology components was excellent, with κ ranging from 0.76 for examination to 0.94 for diagnosis. Of the encounters in the study, 55% were underbilled by an average of $45.26 per encounter, and 18% were overbilled by an average of $51.29 per encounter. The percentages of appropriately coded notes were 16.1% for postgraduate year (PGY) 1, 26.8% for PGY-2, and 39.3% for PGY-3 residents (P < .05). Underbilling was 74.2% for PGY-1, 48.8% for PGY-2, and 42.9% for PGY-3 residents (P < .01). There was significantly less overbilling among PGY-1 residents compared with PGY-2 and PGY-3 residents (9.7% versus 24.4% and 17.9%, respectively; P < .05). Conclusions Our study reports a reliable method for assessing billing in internal medicine resident clinics. It exposed large financial losses, which were attributable to junior residents more than senior residents. The findings highlight the need for educational interventions to improve resident coding and billing. PMID:21975617

    With an increasing demand for oil and diculties in nding new major oil elds, research on methods to improve oil recovery from existing elds is more necessary now than ever. The subject of this thesis is to construct ecient numerical methods for simulation and optimization of oil recovery with...... emphasis on optimal control of water ooding with the use of smartwell technology. We have implemented immiscible ow of water and oil in isothermal reservoirs with isotropic heterogenous permeability elds. We use the method of lines for solution of the partial differential equation (PDE) system that governs...... size control in order to minimize the computational cost per simulation. We implement a numerical method for nonlinear model predictive control (NMPC) along with smart-well technology to maximize the net present value (NPV) of an oil reservoir. The optimization is based on quasi-Newton sequential...

    Reservoir geochemistry has traditionally used the gas chromatographic fingerprinting method and star diagrams to provide evidence of petroleum reservoir compartmentalization. Recently alternative techniques such as Fourier Transform Infra Red (FTIR) spectroscopy have been postulated to aid the evaluation of reservoir compartmentalization, and to characterize the geochemical evolution of oils from individual reservoirs. FTIR spectroscopy was applied successfully in the Tarragona Basin, Offshore N.E. Spain, validating the method to identify oils from different reservoirs. Moreover the method was successfully applied to provide evidence of compositional differences in oils from a faulted reservoir (El Furrial field, Venezuela), in which GC fingerprints failed to differentiate the oils. FTIR spectroscopy therefore, proves to be a complementary tool for reservoir compartmentalization studies. (author)
