    The final steps of generating electricity from concentrated solar power technologies are similar to conventional thermal processes, since steam or gas is also employed for moving turbines or pistons. The fundamental difference lies on the fact that steam or hot gas is generated by solar radiation instead of fossil fuels or nuclear heat. The cheapest electricity generated from solar energy has been achieved with large-scale power stations based on this concept. Computer simulations represent a low-cost option for the design of thermal systems. The present study aims to develop a methodology for the transient simulation of a micro-scale solar-thermal power plant (120 kWe) which should be appropriate in terms of accuracy and computational effort. The facility considered can optionally operate as a cogeneration plant producing electric power as well as chilled water. Solar radiation is collected by parabolic troughs, electricity is generated by an organic Rankine cycle and chilled water is produced by an absorption cooling cycle. The organic Rankine cycle is of interest because it allows for a plant with relatively simple structure and automated operation. The simulation methodology proposed in this study is implemented in TRNSYS with new components (TYPEs) developed for the solar field and thermal cycles. The parabolic trough field component is based on an experimental efficiency curve of the solar collector. In the case of the Rankine and absorption cycles, the components are based on performance polynomials generated with EES from detailed thermodynamic models, which are calibrated with performance data from manufacturers. Distinct plant configurations are considered. An optimization algorithm is used for searching the best operating point in each case. Results are presented for the following Brazilian sites: Fortaleza, Petrolina and Bom Jesus da Lapa. The latter offers the highest global plant performance.

    One of the potential areas for energy saving in Central Electric Power Plants are the auxiliaries system, so as to based in a preliminary energy diagnosis and considering that energy saving measures would be taken, going from the instrumentation, operational changes in equipment, as well as in using velocity variators in motors, it turns out to be that the energy consumption of auxiliaries at 75% load in a 150 MW thermal power plant varies from 3% to 4% and for the case of a 350 MW power plant the energy consumption of the auxiliaries represents 2 to 3.5%. Nowadays this consumption are above 6%. Considering that the country has 40 units with capacities varying from 150 to 350 MW, the economical and the fuel saving would be substantial. This paper will present a summary of the methodology to be used to carry out this type of projects. [Espanol] Una de las areas potenciales de ahorro de energia en centrales termoelectricas son los sistemas auxiliares, de tal manera que basados en un diagnostico energetico preliminar y considerando que se aplicarian las medidas de ahorro de energia que van desde la instrumentacion, cambios operativos en equipos, asi como el uso de variadores de velocidad en motores, se tienen que los consumos de auxiliares para un 75% de carga en una central termoelectrica de 150 MW varian desde un 3% hasta un 4% y para el caso de una central termoelectrica de 350 MW, el consumo de auxiliares representa del 2 al 3.5%. Hoy en dia dichos consumos estan por encima del 6%. Si consideramos que el pais cuenta con 40 unidades que varian desde 150 MW hasta 350 MW, entonces los ahorros economicos y de combustible serian impactantes. La presente ponencia mostrara un resumen de la metodologia a emplear para la realizacion de este tipo de proyectos.

    A methodology to carry out Reliability Centered Maintenance (RCM) studies for hydroelectric power plants is presented. The methodology is an implantation/extension of the guidelines proposed by the Engineering Society for Advanced Mobility Land, Sea and Space in the SAE-JA1012 standard. With the purpose of answering the first five questions, that are set out in that standard, the use of standard ISO14224 is strongly recommended. This approach standardizes failure mechanisms and homogenizes RCM studies with the process of collecting failure and maintenance data. The use of risk matrixes to rank the importance of each failure based on a risk criteria is also proposed. [Spanish] Se presenta una metodologia para realizar estudios de mantenimiento Basado en Confiabilidad (RCM) aplicados a la industria hidroelectrica. La metodologia es una implantacion/ extension realizada por los autores de este trabajo, de los lineamientos propuestos por la Engineering Society for Advanced Mobility Land, Sea and Space en el estandar SAE-JA1012. Para contestar las primeras cinco preguntas del estandar se propone tomar como base los modos y mecanismos de fallas de componentes documentados en la guia para recopilar datos de falla en el estandar ISO-14224. Este enfoque permite estandarizar la descripcion de mecanismos de fallas de los equipos, tanto en el estudio RCM como en el proceso de recopilacion de datos de falla y de mantenimiento, lo que permite retroalimentar el ciclo de mejora continua de los procesos RCM. Tambien se propone el uso de matrices de riesgo para jerarquizar la importancia de los mecanismos de falla con base en el nivel de riesgo.

    This project assisted a private real estate developer in technically assessing the feasibility of integrating a central DHC system into a proposed 72 acre area mixed-use Planned Development (Central Station) just south of the Chicago Central Business District (Loop). The technical assessment concluded that a district heating and cooling system for Central Station will be feasible, provided that a major anchor load can be connected to the system. The system conceived for the site employs a modular approach that adjusts production capacity to actual load growth. The design concept includes gas-fired boilers for heating, gas turbine driven chillers for base loading, electric motor driven chillers for peaking, steam turbines for peak power and back pressure operation, and chilled water storage. Energy will be supplied to the users in the form of steam or low temperature hot water for heating, and low temperature chilled water for cooling.

    This study aimed to develop a methodology to diagnose energetically a water supply system for a irrigation system and for a city. The steps taken were: the energy quality supplied by the utility in relation to level and unbalanced of the supplied voltage; the electrical energy consumption and demand for the pumping station; the study of the electrical and hydraulic load's characteristics; the tariff and demand contracts optimization; the water storage capacity; and the working hours management. This methodology was tested and validated for the water pumping station in a town of about 70,000 inhabitants. Among the proposed actions, which saved the most, were: the sizing of pumps and motors and the optimization of tariff and demand contracts. It was noted that this methodology is simple and easy to apply and there is a great potential for saving energy up to 52%. (author)

    1984-01-01

    Both Centralized and Distributed approaches are being evaluated for the installation of Environmental Control and Life Support (ECLS) equipment in the Space Station. In the Centralized facility concept, integrated processing equipment is located in two modules with plumbing used to circulate ECLS services throughout the Station. The Distributed approach locates the ECLS subsystems in every module of the Space Station with each subsystem designed to meet its own module needs. This paper defines the two approaches and how the advantages and disadvantages of each are tied to the choice of Space Station architecture. Other considerations and evaluations include: crew movement, Station evolution and the ducting impact needed to circulate ECLS services from centrally located processing equipment.

  1. The ANSS Station Information System: A Centralized Station Metadata Repository for Populating, Managing and Distributing Seismic Station Metadata

    Maintaining and archiving accurate site metadata is critical for seismic network operations. The Advanced National Seismic System (ANSS) Station Information System (SIS) is a repository of seismic network field equipment, equipment response, and other site information. Currently, there are 187 different sensor models and 114 data-logger models in SIS. SIS has a web-based user interface that allows network operators to enter information about seismic equipment and assign response parameters to it. It allows users to log entries for sites, equipment, and data streams. Users can also track when equipment is installed, updated, and/or removed from sites. When seismic equipment configurations change for a site, SIS computes the overall gain of a data channel by combining the response parameters of the underlying hardware components. Users can then distribute this metadata in standardized formats such as FDSN StationXML or dataless SEED. One powerful advantage of SIS is that existing data in the repository can be leveraged: e.g., new instruments can be assigned response parameters from the Incorporated Research Institutions for Seismology (IRIS) Nominal Response Library (NRL), or from a similar instrument already in the inventory, thereby reducing the amount of time needed to determine parameters when new equipment (or models) are introduced into a network. SIS is also useful for managing field equipment that does not produce seismic data (eg power systems, telemetry devices or GPS receivers) and gives the network operator a comprehensive view of site field work. SIS allows users to generate field logs to document activities and inventory at sites. Thus, operators can also use SIS reporting capabilities to improve planning and maintenance of the network. Queries such as how many sensors of a certain model are installed or what pieces of equipment have active problem reports are just a few examples of the type of information that is available to SIS users.

    Lung cancer remains the leading cause of cancer death in the United States and is expected to account for nearly 30% of all cancer deaths in 2007. Central to the lung-cancer diagnosis and staging process is the assessment of the central chest lymph nodes. This assessment typically requires two major stages: (1) location of the lymph nodes in a three-dimensional (3D) high-resolution volumetric multi-detector computed-tomography (MDCT) image of the chest; (2) subsequent nodal sampling using transbronchial needle aspiration (TBNA). We describe a computer-based system for automatically locating the central chest lymph-node stations in a 3D MDCT image. Automated analysis methods are first run that extract the airway tree, airway-tree centerlines, aorta, pulmonary artery, lungs, key skeletal structures, and major-airway labels. This information provides geometrical and anatomical cues for localizing the major nodal stations. Our system demarcates these stations, conforming to criteria outlined for the Mountain and Wang standard classification systems. Visualization tools within the system then enable the user to interact with these stations to locate visible lymph nodes. Results derived from a set of human 3D MDCT chest images illustrate the usage and efficacy of the system.

    2014-01-01

    A fortuitous arrangement of a west-facing solar cell and a bracket on the Apollo 12 ALSEP (Apollo Lunar Surface Experiments Package) has allowed us to precisely determine the relative position of the Sun near sunset relative to the Apollo 12 central station over a period of nearly 8 years. The small bracket, mounted on the central station due west of the cell, casts a shadow on the cell near sunset, decreasing the output of the cell proportional to the area of shadow covering the cell. The pattern of shadowing by the bracket gives good agreement with the known change of solar azimuth on a yearly timescale, but the pattern gradually but constantly changed from year-to-year, in a manner inconsistent with the known and changing position of the Sun.

  9. Recent temperature trends at mountain stations on the southern slope of the central Himalayas

    2013-02-01

    Insufficient long-term in situ observations and complex topographic conditions pose major problems in quantifying the magnitude of climatic trends in mountainous regions such as Nepal. Presented here is three decades (1980–2009) of data on annual maximum, minimum and average temperature trends from 13 mountain stations on the southern slope of the central Himalayas. The stations are located at elevations between 1304 and 2566 m above sea level and with varied topography. Spatial analyses of the average temperature trend show warming in most of the stations. The magnitude of warming is higher for maximum temperatures, while minimum temperatures exhibit larger variability such as positive, negative or no change. These results are consistent with patterns reported in some parts of the Indian subcontinent and Upper Indus Basin, but different from conditions on the Tibetan Plateau (China), where the warming of minimum temperatures is more prominent than that of the maximum temperatures. From the temporal variations, a dramatic increase in temperature is observed in the latest decade, particularly in the average and maximum temperatures. The results from the cumulative sum chart analyses suggest that the thermal regime shifted in 1997. The dramatic enhancement of average temperature in the last decade is strongly consistent with the result of contemporary studies of the surrounding regions, where warming is attributed to an increase in anthropogenic greenhouse gases. However, as in the western Himalayas and the Upper Indus Basin, the mountain stations on the southern slope of the central Himalayas show variability in temperature trends, particularly for the minimum temperature. This inhomogeneous trend is likely ascribed to the differences in topography and microclimatic regime of the observed stations.

    With the rapid growth in the no. of seismic stations globally, manual data processing for routine analysis as well as determination of seismic observables becomes more and more impractical. Therefore, automated schemes are inevitable to handle these large data volumes. For surface wave tomography, phase velocity dispersion curves of fundamental mode surface waves yield information on the isotropic as well as anisotropic structure of the crust and upper mantle. We measure inter-station phase velocity dispersion curves through cross correlation of vertical component (Rayleigh wave) and transverse component (Love wave) seismograms. We have developed a scheme to automate this well established inter-station method, which automatically selects the smooth parts of observed phase velocity dispersion curves, and thus obtain path average phase velocity dispersion curve of each inter-station path. After testing various parameters for automation of the procedure we finally confined the method to three parameters only, namely (1) difference of the measured phase velocity curve from a background model, (2) a smoothness constraint and (3) a length criterion. We performed rigorous tests to optimize the parameters and obtained optimal values of these three parameters. We successfully applied the method to more than one hundred thousand inter station paths in central and northern Europe which involved more than one million cross correlations on 20 years of the data of the permanent networks. The method was also tested on temporary deployments e.g. TOR, PASSEQ, SVEKALPKO etc, across Europe. After inversion of the fundamental mode phase velocity dispersion curves for both Rayleigh and Love waves, we obtain high resolution anisotropic phase velocity maps for periods between 10 and 250 seconds with a lateral resolution between about 50 to 100 kilometers. Well known features of upper mantle structure in central Europe are well resolved in our phase velocity maps. Distinct differences

    This work presents the methodology for analysis of generation/cogeneration projects in NGV filling stations, determining the influence of critical parameters in its technical-economic viability. To achieve this methodology, it was necessary to define parameters that influence directly or indirectly the size of a generating system, as the total electric demand of the filling station, ratio (power of the compressor) / (total installed power), load factor, factor of simultaneity, technical data of major equipment, among others. The methodology has been validated by comparing with data measured in a NGV filling station and allows screening and identifying customers with technical feasibility to evolve in a generation or cogeneration project. The cogeneration with NG generators was highlighted during the analysis of the NGV filling stations and was feasible for establishments which have large thermal demand, as filling stations along the road with large amounts of electric showers in changing rooms.

    In this article the methodology followed to diagnose the performance of the equipment where heat is transferred from the feed water, condensate and circulation water systems in fossil power plants (FPP). The data collection is made with the unit in normal operation, using local instrumentation without taking the equipment out of service for its installation. The equipment diagnosis is made through the analysis of the collected data in actual operation and the design data; for this purpose a thermal balance of the interested systems is performed to obtain all the conditions an operation data. Later on the performance indicative parameters (PIP) of actual operation and design are calculated and compared one against the other. Such a comparison reveals the performance deterioration and the possible equipment faults. The data obtained and the supplementary information are stored in a data base whose objective is that Comision Federal de Electricidad has on hand a prompt access to them in order to control the performance, compare them among similar units and power stations, and inclusively verify possible recurrent causes of low availability in the referred systems.

    In this work a methodology developed to carry out the economical analysis of the fuel cycle of a nuclear reactor is presented. The methodology was applied to the Laguna Verde Nuclear Power Station (CNLV). The design of the reload scenarios of the CNLV are made with the Core Master Presto code (CM-Presto), three-dimensional simulator of the reactor core, the launched data by this, as well as the information of the Energy use plan (PUE), it allowed us to obtain reliable results through the fitness of an algorithm of economic calculation that considers all the components of the fuel cycle to present worth. With the application of the methodology it was obtained the generated energy, as well as their respective cost of each sub lot type of assemblies by operation cycle, from the start-up of the CNLV until September 13, 2002. Using the present worth method its were moved all the values at November 5, 1988, date of operation beginning. To the final of the analysis an even cost of 6.188 mills/kWh was obtained for those first 9 cycles of the Unit 1 of the CNLV, being observed that the costs of those first 3 operation cycles are the more elevated. Considering only the values starting from the cycle 4, the levelled cost turns out to be of 5.96 mills/kWh. It was also obtained the cost by fuel lot to evaluate the performance of assemble with the same physical composition. (Author)

  2. System studies of coal fired-closed cycle MHD for central station power plants

    1976-01-01

    This paper presents a discussion of the closed cycle MHD results obtained in a recent study of various advanced energy conversion (ECAS) power systems. The study was part of the first phase of this ECAS study. Since this was the first opportunity to evaluate the coal fired closed cycle MHD system, a number of iterations were required to partially optimize the system. The present paper deals with the latter part of the study in which the direct coal fired, MHD topping-steam bottoming cycle was established as the current choice for central station power generation. The emphasis of the paper is on the background assumptions and the conclusions that can be drawn from the closed cycle MHD analysis. The author concludes that closed cycle MHD has efficiencies comparable to that of open cycle MHD and that both systems are considerably more efficient than the other system studies in Phase 1 of the GE ECAS. Its cost will possibly be slightly higher than that of the open cycle MHD system. Also, with reasonable fuel escalation assumptions, both systems can produce lower cost electricity than conventional steam power plants. Suggestions for further work in closed cycle MHD components and systems is made.

  3. Intake-to-delivered-energy ratios for central station and distributed electricity generation in California

    International Nuclear Information System (INIS)

    In previous work, we showed that the intake fraction (iF) for nonreactive primary air pollutants was 20 times higher in central tendency for small-scale, urban-sited distributed electricity generation (DG) sources than for large-scale, central station (CS) power plants in California [Heath, G.A., Granvold, P.W., Hoats, A.S., Nazaroff, W.W., 2006. Intake fraction assessment of the air pollutant exposure implications of a shift toward distributed electricity generation. Atmospheric Environment 40, 7164-7177]. The present paper builds on that study, exploring pollutant- and technology-specific aspects of population inhalation exposure from electricity generation. We compare California's existing CS-based system to one that is more reliant on DG units sited in urban areas. We use Gaussian plume modeling and a GIS-based exposure analysis to assess 25 existing CSs and 11 DG sources hypothetically located in the downtowns of California's most populous cities. We consider population intake of three pollutants - PM2.5, NOx and formaldehyde - directly emitted by five DG technologies - natural gas (NG)-fired turbines, NG internal combustion engines (ICE), NG microturbines, diesel ICEs, and fuel cells with on-site NG reformers. We also consider intake of these pollutants from existing CS facilities, most of which use large NG turbines, as well as from hypothetical facilities located at these same sites but meeting California's best-available control technology standards. After systematically exploring the sensitivity of iF to pollutant decay rate, the iFs for each of the three pollutants for all DG and CS cases are estimated. To efficiently compare the pollutant- and technology-specific exposure potential on an appropriate common basis, a new metric is introduced and evaluated: the intake-to-delivered-energy ratio (IDER). The IDER expresses the mass of pollutant inhaled by an exposed population owing to emissions from an electricity generation unit per quantity of electric

  6. Analysis of ambient air quality trends at selected West Central Airshed Society stations : Tomahawk and Carrot Creek

    International Nuclear Information System (INIS)

    Ambient air trends were evaluated using data collected over a 10 year period from two West Central Airshed Society monitoring stations in rural Alberta. The pollutants studied included ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter (PM2.5). Two approaches were used to evaluate the trends. The first approach used various percentiles of hourly concentration distributions from each year, while the second approach used frequencies of the number of hours in which various benchmark concentrations were exceeded each year. These statistics were assumed to be linear over the period of study. Hypothesis tests were conducted on the best-fit lines to check whether slope of the lines was zero in order to indicate change. Results from both approaches were found to be in good agreement. At the Tomahawk Station, no statistically dominant change was detected in air quality with respect to O3 and PM2.5. However, SO2 and NO2 showed statistically significant decreasing trends. At the Carrot Creek Station, a pronounced decreasing trend in SO2 was observed, but there was no change in O3 and NO2. The decreasing trends observed with SO2 at both stations is consistent with the province's efforts to reduced natural gas flaring and venting. It was cautioned that since the period of study over which trends were examined was short, the changes or lack of changes observed do not necessarily indicate long term trends

    In this communication it is spoken of the cogeneration in large processing power stations with or without electricity surplus, the characteristics of combined cycle power plants and a comparative analysis in a graph entitled Sale price of electricity in combined cycle and cogeneration power plants. The industrial plants, such as refineries, petrochemical, breweries, paper mills and cellulose plants, among others, with steam necessities for their processes, have the technical and economical conditions to cogenerate, that is, to produce steam and electricity simultaneously. In fact, many of such facilities that exist at the moment in any country, count on cogeneration equipment that allows them to obtain their electricity at a very low cost, taking advantage of the existence steam generators that anyway are indispensable to satisfy their demand. In Mexico, given the existing legal frame, the public services of electricity as well as the oil industry are activities of obligatory character for the State. For these reasons, the subject should be part of the agenda of planning of this power sector. The opportunities to which we are referring to, are valid for the small industries, but from the point of view of the national interest, they are more important for the large size facilities and in that rank, the most numerous are indeed in PEMEX, whereas large energy surplus and capacity would result into cogenerations in refineries and petrochemical facilities and they would be of a high value, precisely for the electricity public service, that is, for the Comision Federal de Electricidad (CFE).

    The paper examines the impact of module and array designs on the balance-of-plant costs for flat-plate terrestrial central station power applications. Consideration is given to the following types of arrays: horizontal, tandem, augmented, tilt adjusted, and E-W tracking. The life-cycle cost of a 20-year plant life serves as the costing criteria for making design and cost tradeoffs. A tailored code of accounts is developed for determining consistent photovoltaic power plant costs and providing credible photovoltaic system cost baselines for flat-plate module and array designs by costing several varying array design approaches.

    This paper describes the functionality of the Integral System of Information for the Diagnosis of Predictive Maintenance (SIIDMP) in the thermoelectric centrals, whose primary target is to give support to the personnel related with the maintenance and operation of the thermoelectric central to optimize the application of the inspection, maintenance and its associated costs. It is important to comment that in the generating power stations of Comision Federal de Electricidad (CFE) techniques and methodologies for the preventive and corrective maintenance are applied, in addition of which they count on electronic equipment of operation dedicated to the inspection and control of vibratory equipment. The architecture of the SIIDMP is of the client-server type and for its design and implantation Windows NT 4.0 was used as operating system, SQL Server 7.0 as server and manager of the database, Visual C++ for the programs of data mining, Vision Basic 6.0 for the codification of the application programs and Interface Man-Machine (IMM), the communication mechanism Open Data Base Connectivity (ODBC) to establish the connection with the different data sources, as well as libraries of symbols and graphs that were included in the interface of the user. The main objective of the SIIDMP is to take care of the own necessities on optimization, improvements and savings in the operation of the power stations. With systems like the SIIDMP, a reduction of the costs due to shutdowns by accidental failures of the main equipment is looked for, limiting the deterioration of the equipment, as well as to provide knowledge and aid to all the personnel who take part in the management of the operation and conservation of the facilities of the power station.

    2009-12-01

    Full Text Available Satellite positioning systems allow the fixing of the location of a point on the Earth's surface with very good precision and accuracy. To do this, however, it is necessary to determine the point coordinates taking account the reference system and the movements that affect them because of tectonic plate movements. These reference systems are materialized by a significant number of continuous measurement stations in South America. In SIRGAS (Sistema de Referencia Geocéntrico para las Américas, there are four Analysis Centers that process the data collected from satellites of the Global Navigation Satellite Systems (GNSS, with the primary purpose to maintain the international terrestrial reference frame through calculation of the coordinates and velocities of the continuous GNSS stations of the SIRGAS-CON Network.

    In this work, we demonstrate the quality of the solutions from CIMA, one of the SIRGAS official processing centers operating in Mendoza, Argentina, in comparison with other South American processing centers. The importance of precise calculations of coordinates and velocities in a global frame is also shown. Finally, we give estimations of velocities from stations located within deformation zones in the Central Andes.

    Full Text Available Almost all of the most populated cities in the world have invested heavily on high capacity urban public transit systems. Apart from the direct economic benefits –travel time reduction, environmental benefits, some indirect benefits are the increase in real estate values (residential and commercial, improved accessibility and possible land use changes towards the development of an area. This study investigates the impact of the future central metro stations of Thessaloniki on real estate values. Real estate values can increase up to 11,3% at a distance shorter than 50 m and gradually decrease up to -14% for a distance greater than 500 m. A hedonic analysis is presented so as to determine the influence of metro stations to 52 commercial properties. The results of the investigation indicate that the changes in market are not necessarily connected or totally attributed to the construction of the metro stations. Instead interesting results show that in some cases common belief about the impact of urban public transit systems can be slightly different.

  17. Annex. Decommissioning of a large central-station LMFBR power plant: a comparison with the PWR

    International Nuclear Information System (INIS)

    The decommissioning of a liquid metal fast breeder reactor (LMFBR) is qualitatively compared with that of a more conventional pressurized water reactor (PWR). The PWR and LMFBR are examined for differences which might impact the total station decommissioning costs, and the primary systems of both reactor types are compared to determine if design differences in their radioactive portions would substantially alter the overall balance of costs evaluated in earlier comparative studies of decommissioning alternatives. Consideration of the ease of disassembly, relative quantities of structural material to be treated, and the special aspects related to the sodium coolant indicated that, for otherwise equivalent circumstances, dismantling operations are of corresponding difficulty, decommissioning costs are comparable, and, if the primary sodium is reused in another reactor and proper credit taken, the sodium coolant does not add to the cost of decommissioning

    We present aerosol and trace-gas retrievals from the new Central-African measurement site of Bujumbura, where a new MAX-DOAS instrument and cimel sun photometer have been operational since late 2013. This is the first time that MAX-DOAS measurements are performed in Central Africa, which are critical to resolve the large uncertainties of satellite observations of trace gases and aerosols over this area. The Bujumbura region is a source of strong biogenic compounds and biomass burning products, and invaluable to study the export of African emissions to the Indian ocean. Using the bePRO radiative transfer tool, we retrieve aerosol optical depths (AODs) and vertical extinction profiles for aerosols and trace gases such as NO2 and HCHO. The AOD retrievals are compared to the co-located AERONET sun photometer measurements and further analysed to investigate seasonal and diurnal cycles in the observed variability or to detect biomass-burning events.For the trace gases NO2 and HCHO, the ground-based MAX-DOAS vertical columns and profiles are used for tropospheric trace-gas validation of the GOME-2 and OMI satellites. We further discuss the representativity of the site regarding satelitte comparisons and modelling efforts, given its specific orography.

    The main objective of this research is the development of a location methodology for sitting optimization of small hydro power (SHP) centrals. In order of achieve this goal, a Multi-Criteria Evaluation (MCE) methodology implemented through the use of tools in a GIS environment: Spatial Analysis, Geostatistic Analysis, and Hydrology have been developed. This methodology includes two different models based on the same MCE process. The substantial difference of both models is in the input data and the tools applied to estimate the energy resource and the principal factor of the methodology (caudal or accumulated flow). The first model is generated from caudal data obtained in the study area (El Bierzo), and the second one from pluviometric data and Digital Terrain Model (DTM). Both models include viability maps with greater ability areas to locate SHP facilities. As an additional objective, the study allows contrasting the results of the two developed models to evaluate their similarity. (Author)

  6. Investigation on the environmental radioactivity of the proposed location for Nuclear Power Plant Station in Ujung Watu area, Central Java

    International Nuclear Information System (INIS)

    During the period of November 1981 and March 1983, preliminary investigation of the environmental radioactivity at the proposed location of nuclear power station in Ujung Watu area in Central Java has been carried out. The investigated area covers an area within a radius of 5 km of the proposed location. During this period a total of about 319 environmental samples which consist of soils, grasses, drinking and surface waters, several food-item of agricultural and sea product have been collected. Measurement of exposure and absorbed dose level were also carried out at 52 and 27 locations within the investigated area. Measurement of exposure dose was carried out using scintillation probe detector coupled to rate meter and absorbed dose level was measured using TL-dosemeter. The samples were analysed for the gross - α and β radioactivity, the content of H-3, Cs-137 and Sr-90. Results showed that the radiation level of the area has a range of 4 ± 18 mR/h with an average of about 4.6 x 1.4 mR/h. Absorbed dose showed a value within the range of 4.5 - 6.9 x 10-7 Gy/day with an average value of 6.2 ± 1.2 x 10-7 Gy/day. The value area is within the normal range of natural level. Measurement of fall-out indicated that the integral impact of Cs-137 and Sr-90 from fall-out to this area were about 2.6 MBq/km2 and 1.5 MBg/km2 respectively. However, no Cs-137 and Sr-90 were detected in the samples collected during this study. (author). 9 refs

    A recent innovation of astronauts observing Earth from the International Space Station (ISS) is documenting human footprints by photographing city lights at night time. One of the earliest night-time images from the ISS was the US-Mexico border at El Paso-Ciudad Juarez. The colors, patterns and density of city lights document the differences in the cultural settlement patterns across the border region, as well as within the urban areas themselves. City lights help outline the most populated areas in settlements around the world, and can be used to explore relative population densities, changing patterns of urban/suburban development, transportation networks, spatial relationship to geographic features, and more. The data also provides insight into parameters such as surface roughness for input into local and regional climate modeling and studies of light pollution. The ground resolution of night-time astronaut photography from the ISS is typically an order of magnitude greater than current Defense Meteorological Satellite Program (DMSP) data, and therefore can serve as a "zoom lens" for selected urban areas. Current handheld digital cameras in use on the ISS, optimized for greater light sensitivity, provide opportunities to obtain new detailed imagery of atmospheric phenomena such as airglow, aurora, and noctilucent clouds in addition to documenting urban patterns. ISS astronauts have taken advantage of increasingly sensitive digital cameras to document the world at night in unprecedented detail. In addition, the capability to obtain time-lapse imagery from fixed cameras has been exploited to produce dynamic videos of both changing surface patterns around the world and atmospheric phenomena. We will profile some spectacular images of human settlements over the South-Central U.S., and contrast with other images from around the world.

    A description is presented of the operation of the Combined Cycle Power Stations with Integrated Gasification (CCGI) where the use of solid fuels (coal, vacuum residues, petroleum coke, and biomass) or liquids is possible in a thermal power station with the efficiency and many of the own environmental benefits of the combined cycles. The gasification process is analyzed, that is a thermo-chemical process by means of which a fuel that is in solid state or liquid becomes to the gaseous state by means of a partial oxidation and the obtained gas of this process is called synthesis gas (syngas, by its abbreviations in English) that is used in Combined Cycle Power Stations as a substitute for the natural gas. Also the other components of this type of power stations are shown, such as the air separating unit, and some of the modifications that are due to make to adapt a gas turbine so that it uses syngas, and the considerations of their integration with the air separating unit to optimize the operation of the plant are detailed. A comparison of efficiency values of power stations CCGI with the conventional carbon-electric and the power stations of combined cycle that use natural gas is also shown. Finally the emissions of pollutants of SO{sub 2}, NO{sub x} and CO{sub 2} are analyzed. The possibility of using fuels like petroleum coke and vacuum tower residues that are produced in the Cadereyta refinery is studied for the possible construction of a CCGI power station in Mexico.

Mostrar para os alunos que essa disciplina não é difícil, mas apenas diferente daquilo que estudaram até então, tornou-se nossa meta. A visão espacial é uma habilidade mental localizada no lado direito do cérebro e, assim, quanto mais lúdica for esta aprendizagem, será mais bem assimilada. A proposta é iniciada no sentido de se trabalhar primeiro com sólidos: neles estarão os pontos, retas e planos normalmente abordados na metodologia convencional, nessa ordem. Como conclusão, tem-se que o importante é ressaltar o grande avanço que a Geometria Descritiva traz para quem quer representar graficamente qualquer coisa. Onde há planejamento, projeto e representação gráfica, aí estará a Geometria Descritiva.During many years observing the teaching of design at the Engineering, Mathematics, Architeture and Arts courses, we can note the difficulties of the students to learn it, specially the descriptive geometry.

We want to show to the students that this discipline is not so difficult as they think, but show them that is only different. The spatial vision is a mental skill found at the right side of the brain and the more soft the learning is, the more it is assimilated by the brain. The

The battery swapping mode actually applies battery leasing model and the slow charging technology, and large-scale centralized charging station can be built to recharge the battery, which has become a competitive way to solve this key problem. As a new-born thing, it is lack of theoretical guidance for the planning and operation of large-scale centralized charging station. Given the regional charging demand and considering the initial investment of equipment and the electric energy cost during the operation period, a capacity planning model for centralized charging station was established. The effectivity of the model was tested by a numerical example. Relative analysis demonstrates that battery demand and charging tariff will have great influence on the capacity planning of the centralized charging station.

    The results of measurements of the CO content in the atmospheric thickness by the method of solar molecular-absorption spectroscopy are presented. Over 87 months of observations, the annual mean CO content decreased by ˜19% at a mean rate of changes equal to -(0.14 ± 0.02) atm cm per year. Maxima and minima of seasonal variations most often fall on February and September, respectively. The mean overall amplitude of changes in the CO content during the annual cycle is about 50% of the mean value. The Fourier analysis revealed variations in the CO composition with periods from 3 to 84 months. A simple statistical model satisfactorily describes time changes in the CO content in the atmospheric thickness. The results of measurements of the CO content in the atmospheric thickness are compared with the data of CO measurements in samples of surface air at stations of the Global Atmospheric Watch.

  15. Analysis of geological aspects and visual impact rising from the realisation of a wind power station in an Italian mountain area (Central Appennines)

    International Nuclear Information System (INIS)

    This study evaluates some aspects of the environmental impacts arising from the wind power station in the Central Appennines of Italy, particularly with reference to the geological and geotechnical conditions of the site and the visual impact on the landscape. Starting from a large-scale analysis that takes into account the Appennines orogeny and their geodynamic process, it is possible to define the geological characteristics of the considered area. It is possible to analyse structural and morphological aspects, in this way it is possible to identify the most suitable location of power generators in the area and to optimise the road network. The geo-stratigraphical study aids decisions about foundations, excavations and works of containments. Considerations on earth traspiration and on rill identify the necessity of controlling surface waters, evolutionary phenomena and the soil stability of the considered areas. Particular attention has been given to analyse effects on the landscape. (author)

    We present for the first time spectral behaviour of aerosol optical depths (AODs) over Manora Peak, Nainital located at an altitude of ~2 km in the central Himalayas. The observations were carried out using a Multi-Wavelength Solar Radiometer during January to December 2002. The primary features of the study are (i) larger AOD during afternoon periods compared to forenoon, attributable to change in the ray path from comparatively cleaner environment in the forenoon to polluted environment in the afternoon (ii) extremely low AODs during local winter and a remarkable increase to high values in summer (iii) a distinct change in the spectral dependencies of AODs from a relatively steeper spectra during winter to a shallower one in summer representing both transparent (meteorological aerosols) and polluted summer (urban haze aerosols) skies.The mean aerosol extinction law at Nainital during 2002 is best represented by $0.10 \\lambda^{-0.61}$.

    This paper introduces the summary of the automation system at Kitami Centralized Control Station of Hokkaido Electric Power Co., Ltd. The system has been discussed to apply a more excellent function-dispersed system that can amalgamate the latest opening techniques, and comply with the trend of up-scaling and more complication of the power systems. The system is a large-scale power automating system that integrates the power supply operations throughout the district in addition to the centralized monitoring and control of about 50 power plants and substations in the district. Further, the features of the function dispersed system are exhibited at a possible maximum extent, an operation system using automatic information service functions and graphical user interface was adopted, and the facilitation of operations was further improved. The system is a function-dispersed system that adopts the token ring LAN having excellent real-time performance in the process system, uses the Ethernet in the man-machine system, and couples the processors divided into function units organically with each other. The main devices are duplicated to execute the system operation factor and the data continuity at the maximum level. 2 figs., 1 tab.

    Within the presented study the SoilClim model was tested through various climatic and soil conditions. SoilClim model enables to estimate reference and actual evapotranspiration from defined vegetation cover and consequently the soil water content within two defined layers (named as Moisture control section I and II) could be deduced. The soil temperature in 0.5 m depth is also estimated (on the basis of simple empirical model). Mentioned outputs could be additionally used for identification of soil climate regimes (both Hydric and Thermic) within selected location. The SoilClim works in daily step and needs daily maximum and minimum air temperature, global radiation, precipitation, air humidity and wind speed as input. The brief information about soil layers (field capacity, wilting point, depth) and vegetation cover is necessary. The algorithm for reference evapotranspiration is based on Penman-Monteith method. The main aim of the study was to assess accuracy and suitability of the SoilClim for simulation of soil water content in the two defined layers and temperature in 0.50 m depth. For this purpose the seven stations through central U.S. were selected (by twos from Nebraska, Iowa and Kansas and one from South Dakota). Used measurements were observed from 2004 to 2008. The central European region was represented by Austrian Lysimetric station Gross-Enzersdorf. The data within three different soil profiles and for various crop covers (spring barley, winter wheat, maize and potato) from 1999 to 2004 were used. During introduced reserch SoilClim provided reasonable results of soil moisture for both layers against lysimetric measurements. Agreement between measured and estimated water content (30 days averages) could be described by coefficient of determination (R2) which varied from 0.45 to 0.75. The Mean Bias Error (MBE) for values in daily step was from -12.87 % to 20.66 % and Root Mean Square Error (RMSE) varied from 14.49 % to 34.76 %. The modeling efficiency

  20. Adaptation of Korean rice cultivars under PhilRice, Nueva Ecija Central Experiment Station's agro-climatic conditions

    International Nuclear Information System (INIS)

    Agro-climatic conditions are very vital for growth and development of rice plants. Rice cultivars that were not bred and developed in the Philippines must be properly screened and tested to identify genotypes that will adapt to its new environment. Nine Korean and 3 Philippine rice cultivars were planted at the Philippine Rice Research Institute Central Experiment Station from 2011 dry season to 2013 wet season. The main objective is to test, identify, and recommend Korean rice cultivars adapted to Philippine conditions. Weather data such as solar duration and radiation, relative humidity, rainfall, and temperature generated from Automatic Weather Station (AWS) were used to study the response of Korean and Philippine cultivars. Other data includes plant height, days to 50% flowering and yield. Results showed that there were differences among the cultivars in plant height which ranged from 2.4-14.9 cm. Variation in days to 50% flowering were also observed. Yield also varied but was greater during dry season compared to wet season. Plant height was affected by relative humidity and rainfall especially during sowing and transplanting. During panicle initiation, relative humidity had greater influence on plant height. Other weather parameters such as temperature, solar radiation and duration had negative correlation with plant height. On the other hand, flowering was delayed due to low solar radiation and high rainfall. High correlation was observed between maturity and relative humidity especially during sowing and transplanting. Yield was correlated with solar duration and radiation. Dasanbyeo, Milyang 23, Hanareumbyeo, Hangangchai 1, and Saegyejinmi were identified most adapted Korean cultivars under Nueva Ecija climatic conditions

  1. Set-up and calibration of an outdoor nozzle-type rainfall simulator for soil erosion studies at the Masse experimental station (central Italy)

    This contribution describes the technical characteristics and the preliminary calibration of a rainfall simulator recently installed by the Department of Agricultural, Food and Environmental Sciences (Perugia University) at the Masse experimental station located 20 km south of Perugia, in the region of Umbria (central Italy). The site includes some USLE plots of different length λ = 11 and 22 m and width w = 2, 4 and 8 m, oriented parallel to a 16 % slope and kept free of vegetation by frequent ploughing. Since 2008, the station enabled to collect data from more than 80 erosive events, that were mainly used to investigate the relationship between rainfall characteristics and soil loss. The relevant soil loss variability that characterizes erosive storm events with similar overall characteristics (duration and/or depth) can be explained by the different rainfall profile of erosive storms and by the different antecedent soil aggregate stability. To analyse in more detail these aspects, recently, the Masse experimental station has been equipped with a semi-portable rainfall simulator placed over two micro-plots of 1x1 m each, having the same topographic and pedologic conditions of the adjacent USLE plots. The rainfall simulator consists of four full-cone spray nozzles for each micro-plot, placed at the angles of a 0.18-m square, centred over the plot at a height of 2.7 m above the ground. The operating pressure is regulated by pressure regulating valves and checked by pressure gauges mounted in correspondence of each nozzle. An electronic control unit regulates the start and stop of the inlet solenoid valves. A range of rainfall intensities can be achieved, by activating different combinations of nozzles (15 different intensities) also during the same simulation trial. The particular design of the plots allows to collect separately the runoff volume deriving from the plots and the water volume fallen outside of the plot. In this way it is possible to derive, by

    Many oil industry related sites have become contaminated due to the activities characteristic of this industry, such as oil exploration and production, refining, and petro-chemistry. In Mexico, reported hydrocarbon spills for the year 2000 amounted to 185203, equivalent to 6252 tons (PEMEX, 2000). The first step for the remediation of these polluted sites is to assess the size and intensity of the oil contamination affecting the subsoil and groundwater, followed by a health risk assessment to establish clean up levels. The aim of this work was to characterize the soil and water in a north-central Mexico Oil Storage and Distribution Station (ODSS), in terms of TPHs, gasoline and diesel fractions, BTEX, PAHs, MTBE, and some metals. Besides, measurements of the explosivity index along the ODSS were made and we describe and discuss the risk health assessment analysis performed at the ODSS, as well as the recommendations arising from it. Considering soils with TPH concentrations higher than 2000 mg kg(-1), the contaminated areas corresponding to the railway zone is about 12776.5 m2, to the south of the storage tanks is about 6558 m2, and to the south of the filling tanks is about 783 m2. Total area to be treated is about 20107 m2 (volume of 20107 m3), considering 1m depth. PMID:15963553

    36 years ago one of the most important power projects of Mexico was born; the design and construction of the Nuclear power station Laguna Verde. This project became reality thanks to the commitment of a group of Mexican professionals that gave the best of them for its accomplishment. At that time, there was not in Mexico a legislation that contemplated the environmental protection; nevertheless, the Mexican Constitution anticipates that when in the country there is not legislation for the development of a project, this must adopt the legislation of the country that is selling it. In the specific case of Laguna Verde, the legislation of the United States of America was adopted and in the environmental part it had to issue the first Manifest of Environmental impact, that was called Informe Ambiental para la Contruccion de Laguna Verde en el Estado de Veracruz. This study was performed by several national as well as foreign institutions. Among the most outstanding are the Universidad Nacional Autonoma de Mexico, the Intituto Politecnico Nacional, the Universidad Veracruzana, the Intituto National para la Investigacion de Recursos Biologicos, the Instituto de Ecologia, A.C. With this report, the engineers undertook the task of designing and constructing, the biologists and ecologists to realize the studies to mitigate the effects caused to the environment during the construction and later, during the operation of the Nuclear power station. After 18 years of commercial operation of the power station the present book is completed, in which the results obtained in 1972, when the studies of the environmental report began are compared against the ones obtained throughout this period. It is important to see in the results of the different studies and indicators presented/displayed in this book, that the important changes on the environment are due, to the change of the ground use and the over-exploitation of the natural resources as it happens in almost all the country.

    Extensive wildfires burned in Alaska and western Canada during the summer of 2004. Boreal wildfires are a large source of trace gases and aerosols in the atmosphere. However, little is known about the impact of their emissions on the nitrogen oxides and O3 levels over the Northern Hemisphere. During the summer of 2004, measurements of NO_x and NO_y were made at the PICO-NARE station (Azores Islands, Portugal, 2225 m asl), a location 5--15 days downwind from the fires. Measurements in 10 fire plumes between July and September were analyzed in combination with CO and aerosol black carbon observations, backward trajectories, satellite images, and MOZART simulations, in order to study the effect of boreal fire emissions on nitrogen oxides levels over the central North Atlantic lower free troposphere, and their further potential for O3 formation over this region. During the fire-impacted periods, NO_x, NO_y, and CO levels were extremely high for such a remote region, with enhancements up to 110 pptv, 1000 pptv, 150 ppbv above background, respectively. NO_y was significantly correlated to CO, with an average enhancement ratio of approximately 6 pptv/ppbv. The magnitude of the NO_y/CO enhancement ratio is a significant fraction (~20%) of the estimated NO_x/CO emission ratio from boreal forest fires and is only moderately smaller than previous measurements closer to fires, indicating limited NO_y removal during transport to the site. In addition to NO_y, NO_x was typically correlated to CO, with an average enhancement ratio of approximately 1 pptv/ppbv. Since the major component of NO_y in boreal fires plumes is believed to be PAN, this suggests that decomposition of PAN to NO_x is a significant source of NO_x in the fire plumes arriving to this region. These observations indicate that nitrogen oxides emissions from wildfires can be efficiently transported to the lower free troposphere over the central North Atlantic region. Furthermore, high levels of NO_x and NO_y in

    Recent biomass burning in Southeast Asia has raised global concerns over its adverse effects on visibility, human health, and global climate. The concentrations of total suspended particles (TSPs) and other vapor-phase pollutants (CO and ozone) were monitored at Lulin, an atmospheric background station in central Taiwan in 2008. To evaluate the long-range transport of persistent organic pollutants (POPs) during the Southeast Asia biomass burning event, the atmospheric polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were also measured at Lulin station. The atmospheric PCDD/F and TSP concentrations measured at Lulin station ranged from 0.71-3.41 fg I-TEQ/m(3) and 5.32-55.6 microg/m(3), respectively, during the regular sampling periods. However, significantly higher concentrations of PCDD/Fs, TSPs, CO, and ozone were measured during the spring season. These high concentrations could be the result of long-range transport of the products of Southeast Asia biomass burning. During the Southeast Asia biomass burning event (March 18-24, 2008), an intensive observation program was also carried out at the same station. The results of this observation program indicated that the atmospheric PCDD/F concentration increased dramatically from 2.33 to 390 fg I-TEQ/m(3) (March 19, 2008). The trace gas (CO) of biomass burning also significantly increased to 232 ppb during the same period, while the particle-bound PCDD/Fs in the TSP increased from 28.7 to 109 pg I-TEQ/g-TSP at Lulin station during the burning event. We conclude that there was a significant increase in the PCDD/F concentration in ambient air at a high-altitude background station in central Taiwan during the Southeast Asia biomass burning event.

    Full Text Available During the 2010/11 season nearby the Vostok station the 56th Russian Antarctic Expedition has collected surface snow in a big amount from a 3 m deep pit using 15 220 L vol. containers (about 70 kg snow each. Snow melting and processing by ultra-centrifugation was performed in a clean (class 10 000 and 100 laboratory. Total dust concentrations were not exceeded 37.4 mkg per liter with particle dispersal mode around 2.5 mkm. To analyze the elemental composition of fine dust particles aimed to reveal Antarctic micrometeorites (AMM two electron microscopy devices equipped with different micro-beams were implemented. As a preliminary result, three particles (of 107 analyzed featured by Mg content clearly dominated over Al along with Si and Fe as major elements (a feature of carbonaceous chondrites were observed. By this the Vostok AMM CS11 collection was established. The occurrence of given particles was averaged 2.8% – the factual value obtained for the first time for chondritic type AMM at Vostok which should be considered as the lowest estimate for all other families of AMM. Given the reference profile of total dust content in East Antarctic snow during Holocene (18 mkg/kg the MM deposition in Antarctica was quantified for the first time – 14 tons per day for carbonaceous chondrites for the Vostok AMM CS11 collection and up to 245 tons per day for all MM types for the Concordia AMM DC02 collection. The results obtained allowed to prove that snow cover (ice sheet in total of Central East Antarctica is the best spot (most clean of other natural locations and always below 0 ºC for collecting native MM deposited on the Earth during the last million years and could be useful in deciphering the origin and evolution of solid matter in our Solar System and its effects on Earth-bound biogeochemical and geophysical processes including the life origin. The farther analyses of the Vostok AMMs are in a progress.

    The monitoring of emissions into the atmosphere from thermal power plants is of vital importance. The recently published Board Directive of 24 November 1988 is therefore one step further towards the protection of the environment. As a consequence, power stations need to make a great effort to adapt. We have also seen that power stations have the technology to quantify their emissions and that they appear to have sufficient time available to reduce them. 5 refs., 3 figs., 1 tab.

    This paper presents the methodology for assessment of the storage capacity into a saline aquifer depth and the results of the studies carried out in the central east area of the Duero Basin. The extension of the study area represents about 40% of the basin. This methodology has been conducted under the need of estimate of uncertainty in everything related to behavior of long-term stored CO{sub 2} in geological formations because one of the major challenges associated with this activity is ensuring the retention of stored CO{sub 2} along the period of the required time. The method is based on the implementation of a Geographic Information System as a tool for capture, storage, management and presentation of data in maps, as well as a tool for analysis and modelling through its link to both geostatistical methods and description of CO{sub 2} thermodynamic behaviour in deep geological storage conditions, by using real gases Equations of States, specially the Sterner-Pitzer Cubic Equation of State. All these analyses are accompanied by the error propagation due to the calculations required for the determination of the volume of rock, the vertical accuracy of the topographic layers, as well as other uncertainties associated with the variables required for the characterization of the CO{sub 2} in the storage conditions. The conclusion is that the deep geologic CO{sub 2} storage capacity in the study area is between 1,667 and 11,976 Mt, i.e. between 11 and 81 years of storage capacity with a current spanish CO{sub 2} production of 148 Mt/year.

    For the year 1996, 366 incidents related with clandestine poaching of oil-products were reported in Mexico, 159 in 1997, and 240 in 1998. For the year 2003 (the most recently reported figure), there were 136 events. Petroleos Mexicanos (PEMEX), very concerned with the environmental agenda, has developed programs oriented to diminish contamination levels in all of its oil facilities. This work was aimed at characterizing zones around polyduct segments, pipelines, pumping stations, and right-of-way pipelines located in the center of Mexico. The TPH contaminated sites were, in decreasing order, polyduct km 39 + 150 > polyduct km 25 + 020 > Zoquital > Tepetitlan > Catalina > Venta Prieta > Ceiba. Most of the sampled points showed the presence of more than one of the 16 PAHs considered by USEPA as priority pollutants. Except point TEPE 2A, where no PAHs were detected, all the sampled points showed values from low to medium concentrations; however, values found at the sites did not exceed the limits according to the Mexican or the American legislation. The place with the largest contaminated area corresponded to the polyduct km 39 + 150, with 130 m2 and 260 m3 to be treated. The least contaminated area was that around the JUAN 4 point at Juandho station, with 20 m2 and 22 m3 of contaminated soil. The total area to be treated is about 230 m2 and 497 m3.

  11. Integrated plant safety assessment: systematic evaluation program. Oyster Creek nuclear generating station. GPU Nuclear Corporation and Jersey Central Power and Light Company. Docket No. 50-219

    International Nuclear Information System (INIS)

    The Systematic Evaluation Program was initiated in February 1978 by the US Nuclear Regulatory Commission to review the designs of older operating nuclear reactor plants to reconfirm and document their safety. The review provides (1) an assessment of how these plants compare with current licensing safety requirements relating to selected issues, (2) a basis for deciding on how these differences should be resolved in an integrated plant review, and (3) a documented evaluation of plant safety. This report documents the review of the Oyster Creek Nuclear Generating Station (located in Ocean County, New Jersey), one of ten plants reviewed under Phase II of this program, and indicates how 137 topics selected for review under Phase I of the program were addressed. Equipment and procedural changes have been identified as a result of the review. It is expected that this report will be one of the bases in considering the issuance of a full-term operating license in place of the existing provisional operating license

  12. Mercury in the snow and firn at Summit Station, Central Greenland, and implications for the study of past atmospheric mercury levels

    2008-07-01

    Full Text Available Gaseous Elemental Mercury (Hg° or GEM was investigated at Summit Station, Greenland, in the interstitial air extracted from the perennial snowpack (firn at depths ranging from the surface to 30 m, during summer 2005 and spring 2006. Photolytic production and destruction of Hg° were observed close to the snow surface during summer 2005 and spring 2006, and we observed dark oxidation of GEM up to 270 cm depth in June 2006. Photochemical transformation of gaseous elemental mercury resulted in diel variations in the concentrations of this gas in the near-surface interstitial air, but destruction of Hg° was predominant in June, and production was the main process in July. This seasonal evolution of the chemical mechanisms involving gaseous elemental mercury produces a signal that propagates downward through the firn air, but is unobservably small below 15 m in depth. As a consequence, multi-annual averaged records of GEM concentration should be well preserved in deep firn air at depths below 15 m, and available for the reconstruction of the past atmospheric history of GEM over the last decades.

    With the gradual expansion of power system construction, unattended substation is imperative. The number and type of auxiliary equipment and environmental equipment in station operation are relatively large, so to realize the efficient and centralized monitoring and management of the equipment bears the brunt of difficulties. A new solution of plant station running auxiliary equipment and environmental equipment for centralized monitoring system is designed and proposed based on the relative switch information of automatic control and new sensing technology collect equipment. The system realizes centralized monitoring and management on auxiliary equipment and environment in the station operation by the dispatching terminal, after the communication network of electric power and the internal information network sent back the running state data of auxiliary equipment and environmental equipment in the station operation, which not only greatly improves the quality and efficiency of the equipment operation and maintenance, but also provides a new solution for substation communication network operation and maintenance. It can effectively realize unmanned operation and development of substation.%随着电力系统建设规模日趋壮大,变电站无人化已势在必行。厂站运行辅助设备、环境设备的数量和类型均相对较多,实现设备的高效、集中监控管理便成为了首当其冲的难题。基于自动控制和新型传感技术采集设备的相关开关量信息,设计并提出了一种新型的厂站运行辅助设备及环境设备的集中监测系统解决方案。该方案通过电力通信网和内部信息网络完成厂站运行辅助设备及环境设备运行状态数据的回传,从而实现了地调主站端对厂站运行的辅助设备和环境的集中实时监控和管理,极大地提高了设备运行维护的质量和效率。该研究为今后变电站通信网络的运行和维护提供了一种新的解决

    The induced draft fans of the 350 MW units of a Thermo-electric power plant presented problems consisting of the failure of the capacity of gases extraction, together with the presence of cracks in the blades; this condition was observed since the stage of putting into service. Consequently, losses have been originated in the availability in two units, as well as, losses due to the manufacture of new impellers, which also originated that, in some cases, that the measures of the impellers, locally manufactured, differed from the originals, resulting in differences in the unit's efficiency. [Spanish] Los ventiladores tiro inducido de las unidades de 350 MW de una Central Termoelectrica presentaban una problematica consistente en la falla de capacidad de extraccion de gases, aunado a la presencia de fracturas en las aspas de los impulsores, esta condicion se observo desde la etapa de puesta en servicio. En consecuencia se han ocasionado perdidas de disponibilidad en dos unidades, asi como tambien, perdidas debido a la fabricacion de nuevos impulsores, lo que tambien origino que, en algunos casos, las medidas de los impulsores, fabricados localmente, diferian de los originales, dando como resultado diferencias en la eficiencia de las unidades.

    Under the expectations of expansion of electric power generation in Mexico, this work exposes the development of a conventional and intelligent generalized supervisory control (CSG) for a combined cycle generation power plant. This one allows to obtain the optimal operation of the power plant through the automatic starting of the generating units and to obtain the maximum possible amount of electrical power in automatic and safe form. For the development of the CSG a control loop by temperature was implemented for the gas turbine system and a control loop by strangled pressure for the gas turbine and a control loop by strangled pressure for the steam turbine. The design of these supervisory systems was made with base in the critical limits on the involved variables of the process: blading average temperature, for the gas turbine (GT) and strangled pressure for the steam turbine (ST) [Spanish] Bajo estas expectativas de expansion de generacion de energia en Mexico, este trabajo expone el desarrollo de un control supervisorio generalizado (CSG) para una central generacion de ciclo combinado.

Para el desarrollo del CSG se implanto un lazo de control por temperatura para el sistema de turbina de gas y un lazo de control por presion estrangulada para la turbina de gas y un lazo de control por presion estrangulada para la turbina de vapor. El diseno de estos sistemas supervisorio se realizo con base en los limites criticos de las variables del proceso involucradas: temperatura promedio de empaletado para la turbina de gas (TG) y presion estrangulada para la turbina de vapor (TV)

    A number of different possible programs for nuclear power stations of various types are presented in this survey. These programs are established in relation to the use of uranium and thorium in amounts similar to those that shall probably be produced in France during the next fifteen years. As it is possible to draw plans for nuclear power stations in which several processes exist simultaneously, an unlimited number of variations being thinkable, this survey is limited to successive analysis of the results obtained by use of only one of each of the following three systems: - system natural uranium-graphite, - system natural uranium-heavy water, -system enriched uranium-pressurised light water. All schemes are considered as assemblages of these three simple systems. The effects of plutonium recycling are also considered for each system. The electric power installed and the capacity of stations situated up-stream and down-stream have been calculated by this method and an attempt has been made to establish the sum to be invested during the fifteen years necessary for the launching of the programs scheduled. A table of timing for the investments groups the results obtained. Considering the fact that French availabilities in capital shall not be unlimited during the coming years, this way of presenting the results seems to be interesting. (author)Fren.

    of the computation, the programming languages and the numerical methods allow to develop mathematical models that simulate in an approximate manner the processes to control, as it is the case of the combined cycle thermoelectric power station and in this way making the evaluation of algorithms of modern control possible. In chapter I a functional description of the steam turbine process is given. Since this belongs to a combined cycle thermoelectric power station, it is begun with the description of this power station, later to emphasize the subsystem of the steam turbine and emphasize each one of the elements that comprise this last one. [Espanol] Este trabajo de investigacion esta orientado a disenar, desarrollar y validar un algoritmo de control moderno, que permita la obtencion de mejores desempenos en el control de velocidad de una turbina de vapor perteneciente a una central termoelectrica de ciclo combinado, en todo el intervalo de operacion, asi como la obtencion de mejores desempenos en el control de la cantidad de megawatts generados por la misma cuando esta acoplada a un generador electrico, comparando el desempeno con el obtenido mediante el controlador convencional existente. Los cambios en la referencia de velocidad o carga, son a solicitud del operador y se dan siempre en forma de rampa, indicando la rapidez con la que se desea efectuar el cambio de valor en la referencia. Esta es la razon por la cual el objetivo principal del control a disenar es realizar un buen seguimiento a referencias del tipo rampa. En el subsistema de la turbina de vapor existente el inconveniente de que las valvulas que regulan el flujo de vapor hacia la turbina, presentan un acoplamiento con la valvula del bypass que permite derivar el flujo de vapor hacia el condensador principal sin tener que pasar por la turbina. Es por esto que se propone un control multivariable que contemple la interaccion que se presenta entre las valvulas antes mencionadas, partiendo de un diseno

    The project of installation of speed variator in fossil power stations (CT's) of Comision Federal de Electricidad (CFE), as an energy saving measure, is a pilot project that began with the support of the Subdivision de Generacion, and promoted by the Energy Saving Program of the Electric Sector (PAESE), with the putting in operation of an equipment in the condensate pump of the Punta Prieta II C. T. U3. The energy saving observed was substantial, fluctuating between the 19.4% at high loads (at 90% load) and the 71.1% at low loads (at 40% load) of the generating unit. With these results, it was decided to extend the scope of the project with the installation of 6 more equipment for equal number of fossil power stations, located in 4 of the 5 Regions of Generation. The fossil power stations, selected for this stage of the project were: C. T. Felipe Carrillo Puerto U1, C.T. Lerma U4, C.T. Salamanca U1, C.T. Monterrey U6, C.T. Francisco Villa U3 and the C.T. Punta Prieta II-U1. The equipment was in operation during the first quarter of 1998, and the first results indicate an energy savings average per equipment, between 39% and 52%. The recovery of the investment fluctuates between the 48.4% and the 87.6% in less than two years of operation, with which a maximum period of recovery of 3 years is expected. The estimated potential of energy saving, considering the application of these devices in condensate pumps, feedwater pumps (where no speed variator is installed) forced draft fans, induced draft fans and gas recirculation fans, as well as circulation water pumps, of the existing Generating Power stations, ascends to an annual total of 830,000, which represents an approximate 9.4% of the National consumption of self services.

    The scope of this project was changed during the course of the project. Phase I of the project was to construct a site similar to the site at Central West Virginia Regional Airport in Charleston, WV to show that duplication of the site was a feasible method of conducting hydrogen stations. Phase II of the project was necessitated due to a lack of funding that was planned for the development of the station in Morgantown. The US Department of Energy determined that the station in Charleston would be dismantled and moved to Morgantown and reassembled at the Morgantown site. This necessitated storage of the components of the station for almost a year at the NAFTC Headquarters which caused a number of issues with the equipment that will be discussed in later portions of this report. This report will consist of PHASE I and PHASE II with discussions on each of the tasks scheduled for each phase of the project.

    A relevant task performed by Comision Federal de Electricidad (CFE) is the analysis of the structural behavior and safety assessment of the country`s large electric energy generating stations. This task is performed capturing, revising an analyzing the information generated by measuring instruments installed in the power station civil structures. Such activity generates a large amount of data and the collection, analysis and assessment is a long and tiresome process; additionally, the generated information is kept in plain isolated files, that causes sluggishness in the process and delays in the access to the information. This article describes the characteristics of the Information System for Structure Measurements (Sistema de Informacion de Medicion de Estructuras) (SIME), developed by the Instituto de Investigaciones Electricas (IIE) for CFE in order to enhance the opportunity for the information management. SIME captures, arranges, stores and reports the data obtained from the measurements at the works with great efficiency and flexibility.

    The anomaly of control rod cluster drop time revealed at Guandong Nuclear Power Station in Daya Bay and in the Chooz B1 pilot unit for the N4 series, led to the replacement of the M1 type control rod cluster guide tubes with 1300 MWe PWR type guide tubes, adapted to the geometry of the Guandong reactors and the 1450 MWe reactors of the N4 series. The comparison of the drop times obtained with the 1300 MWe type control rod cluster guide 1300 MWe type control rod cluster guide tubes gave satisfactory results. These met the safety criterion for N4 series control rod cluster drop times (2.15 under hot shutdown conditions). The drop time tests which will be carried out in middle of and at the end of cycle 1 of Chooz B1 should make it possible to finally validate the solution already successfully implemented at Guandong. However, this anomaly has revealed the limits of representativeness of the experimental test loops with regard to the real reactor configuration. In view of this, it has been deemed necessary to ask Electricite de France to pursue its analysis both on the understanding of the phenomena which led to this anomaly and on the limits of the representativeness of the experimental test loops.

    Between 1987 and 1989 10,55 million ecus were given by the European Commission's Demonstration Programme for the construction of the Emile Huchet power station using circulating fluidized bed combustion technology. The power station was constructed jointly by Charbonnages de France, COREAL, Stein Industrie and Lurgi. An important feature was its ability to burn coal preparation wastes cleanly. Despite burning poor quality fuel its emissions are well below the maximum standards. Other stations of this type are now planned in France.

    Full Text Available OBJETIVO: comparar duas metodologias para o cálculo do volume placentário em gestações normais de termo: a do princípio de Arquimedes e a do volume do cilindro, para estimar a densidade absoluta da placenta. Definir a metodologia mais adequada para o cálculo do volume e densidade placentários, que se relacione com o peso e classificação do recém-nascido. MÉTODOS: foram estudadas 50 placentas provenientes de gestações de termo sem complicações e calculados o volume e a densidade absoluta placentários: a pelo princípio de Arquimedes e b na suposição de que a placenta seria uma secção de cilindro com duas alturas diferentes do bolo placentário: com a altura média e com a altura da média aritmética do centro e extremidades. As densidades absolutas placentárias foram calculadas pelo quociente entre o peso ao ar da placenta e os diferentes volumes. RESULTADOS: a maioria das gestantes eram multíparas, idade média de 25,4 anos, volume placentário médio entre 547,8 e 610 cmsuperscript three e densidade média entre 0,94 e 1,14 g/cmsuperscript three, dependendo da metodologia empregada. CONCLUSÕES: a metodologia mais adequada para estimar o volume placentário no termo foi a do princípio de Arquimedes, pela melhor correlação com o peso dos recém-nascidos, o índice placentário e a classificação do peso dos recém-nascidos em relação à idade gestacional.

  2. Shippingport station communications program

    International Nuclear Information System (INIS)

    At the Shippingport Station Decommissioning Project, the central idea of the communications program that was developed for use was purposely designed to be as uncomplicated as possible. The central theme, that was developed and communicated, is that all nuclear plants will someday need to be retired and also decommissioned. The Shippingport Plant, originally constructed as a demonstration nuclear power plant, was now being decommissioned as a demonstration to the world-wide nuclear industry that this evolution can be done in a safe and cost-effective manner. Furthermore, the technology currently exists to complete this process. The new phase of the communications program was initiated even before the responsibility for the plant was transferred from Duquesne Light to GE. With such a change forthcoming, it was necessary to inform local officials of these plans, and the reasons for them. Equally important was the need to inform a variety of agencies and offices in the three-state area of the changes, and the continuing need to involve them in the Site Emergency Plan. This document was also revised in recognition of changing site conditions, as well as the changes in responsibility. 1 ref

    A brief description of a combined cycle power station that uses synthesis gas, better known as CCGI, is presented. The costs of the initial investment of several plants of this type, that have been described in literature, are analyzed and the predictions that different experts do on the costs that are expected in the near future are reviewed. Also the maintenance expenses that would be expected during the normal operation and the main maintenance are examined. The availability factors that reasonably must be considered based on the recent experiences are analyzed. Afterwards the sense which that the plant factor has in one of natural gas and one of synthesis, where generally are used as base plant. The costs of the different fuels that can be used in a CCGI are examined. Finally the leveled cost of the energy for both cases is calculated and the sensitivity of both to the cost of the respective fuels is examined. The result is presented in graphical form to show in a first attempt, the circumstances under which one or another technology could be preferable. It is made clear that the data used in this brief study are the best reasoned estimation and in no way they must be considered as definitive, in special in those of investment and maintenance of the CCGI where the operation history is still short.

    Full Text Available Nos últimos anos um número relativamente grande de sistemas especialistas têm sido produzidos, tanto pela indústria quanto em centros de pesquisa. Algumas destas aplicações têm sido empregadas para resolver problemas práticos, mas a maior parte delas não foi além do estágio de protótipo. Estes sistemas são normalmente desenvolvidos através de um processo relativamente informal e empírico, o qual envolve a implementação de um protótipo simplificado já nos estágios iniciais de aquisição do conhecimento. Esta abordagem tem sido bastante criticada pelas dificuldades de re-implementaçâo do conhecimento. Mais recentemente, algumas metodologias formais para a produção de sistemas especialistas têm sido propostas. Embora tais metodologias prescrevam diversas recomendações úteis, que podem ser seguidas em inúmeros casos práticos, nenhuma delas provou ainda ser aplicável de forma integral em uma ampla gama de situações. A primeira parte deste artigo consiste em uma rápida revisão das principais metodologias propostas. A segunda parte descreve o procedimento adotado durante o desenvolvimento de um sistema especialista para o planejamento de conjuntos habitacionais, denominado House Planner.Several knowledege based systems have been produced in the last decade, both in the industry and in research institutes. Some of these applications have been used in practical situations, but most of them have not been developed beyond the prototype stage. Such systems are usually desingned through an informal and empiric process which involves the implementation of a simple prototype of the system in the early phases of knowledge acquisition. This approach has beem widely criticized because it can make both the re-implementation and updating of knowledege bases cubersome, and seriously distort the way knowledge is represented. For this reason, a number of more formal methodologies for developing knowledge based systems have been

    This volume presents the results of the starter event analysis and the event tree analysis for the Unit 1 of the Laguna Verde nuclear power station. The starter event analysis includes the identification of all those internal events which cause a disturbance to the normal operation of the power station and require mitigation. Those called external events stay beyond the reach of this study. For the analysis of the Laguna Verde power station eight transient categories were identified, three categories of loss of coolant accidents (LOCA) inside the container, a LOCA out of the primary container, as well as the vessel break. The event trees analysis involves the development of the possible accident sequences for each category of starter events. Events trees by systems for the different types of LOCA and for all the transients were constructed. It was constructed the event tree for the total loss of alternating current, which represents an extension of the event tree for the loss of external power transient. Also the event tree by systems for the anticipated transients without scram was developed (ATWS). The events trees for the accident sequences includes the sequences evaluation with vulnerable nucleus, that is to say those sequences in which it is had an adequate cooling of nucleus but the remoting systems of residual heat had failed. In order to model adequately the previous, headings were added to the event tree for developing the sequences until the point where be solved the nucleus state. This process includes: the determination of the failure pressure of the primary container, the evaluation of the environment generated in the reactor building as result of the container failure or cracked of itself, the determination of the localization of the components in the reactor building and the construction of boolean expressions to estimate the failure of the subordinated components to an severe environment.

    2014-06-01

    Full Text Available O diagnóstico automático de doenças da retina baseado em processamento de imagem vê frequentemente a sua precisão comprometida pela dificuldade intrínseca na deteção de estruturas anormais e por deficiências na aquisição de imagem. Em cenários de rastreio, estas deficiências podem levar a que um número significativo de imagens tenham de ser repetidas, implicando custos e ineficiência do sistema. Neste artigo propõe-se uma metodologia que avalia de forma automática a qualidade das imagens captadas possibilitando ao operador repetir a aquisição caso se justifique. O método proposto identifica diferentes tipos de artefactos com base na sua forma, cor e intensidade. Utilizando um conjunto de 61 imagens foi obtida uma sensibilidade de 97% com 0.12 falsos positivos por imagem na deteção do artefacto central e 73% de sensibilidade com 0.36 de falsos positivos para os reflexos luminosos. Estes resultados podem considerar-se positivos tendo em conta a baixa qualidade e a heterogeneidade das imagens processadas.

    Full Text Available Muitos pesquisadores do setor turístico têm utilizado a metodologia da capacidade de carga. A idéia básica é estabelecer um número máximo de visitantes em uma determinada localidade, com o objetivo de minimizar os impactos provocados pela visitação. Entretanto, esta metodologia está incompleta ao atrelar os impactos da visitação apenas ao número de visitantes, deixando de considerar aspectos subjetivos e qualitativos relacionados ao turismo. Esta pesquisa demonstra a falta de cientificidade desta metodologia e salienta que limitar o número de visitantes é apenas um dos métodos de controle dos impactos provocados pelo turismo. Many researchers in the tourism sector have used the methodology of carrying capacity. The basic principie is to establish a maximum number of visitors in some place in order to minimize the impact of tourism. However, this methodology is incomplete as it only relates the impacts of tourist activity to the number of visitors, without considering some of the subjective and qualitative aspects of the effects of tourism. This research demonstrates the unscientific nature of this methodology and stresses that limiting the number of visitors to a locality is only one method to control the impacts of tourism.

  10. Underground location of nuclear power stations

    International Nuclear Information System (INIS)

    In Japan where the population is dense and the land is narrow, the conventional location of nuclear power stations on the ground will become very difficult sooner or later. At this time, it is very important to establish the new location method such as underground location, Quaternary ground location and offshore location as the method of expanding the location for nuclear power stations from the viewpoint of the long term demand and supply of electric power. As for underground location, the technology of constructing an underground cavity has been already fostered basically by the construction of large scale cavities for underground pumping-up power stations in the last 20 years. In France, Norway and Sweden, there are the examples of the construction of underground nuclear power stations. In this way, the opportunity of the underground location and construction of nuclear power stations seems to be sufficiently heightened, and the basic research has been carried out also in the Central Research Institute of Electric Power Industry. In this paper, as to underground nuclear power stations as one of the forms of utilizing underground space, the concept, the advantage in aseismatic capability, the safety at the time of a supposed accident, and the economical efficiency are discussed.

  15. O ESTUDO DE CASOS NA PERSPECTIVA DA METODOLOGIA JURÍDICO-FILOSÓFICA

    Directory of Open Access Journals (Sweden)

    Alfredo de J. Flores

    2009-12-01

    Full Text Available Durante o predomínio do Idealismo iluminista e na época do Positivismo exegético e jurídico dos séc. XIX e XX, pode-se afirmar que o método de estudo de casos no Direito foi deixado em segundo plano. Atualmente, esse método apresenta uma importância inegável, correspondendo a uma resposta ao dogmatismo anterior. Entretanto, é possível apontar que o estudo de casos também representa um retorno a padrões de percepção do fenômeno jurídico que sempre estiveram presentes na tradição jurídica ocidental, de uma forma ou de outra. É o que se nota quando se faz alusão à metodologia das ciências práticas que advém da tradição filosófica grega de Platão e Aristóteles e que se aperfeiçoa com o Direito romano e com os estudos medievais. Com isso, busca-se provar que o estudo de casos no Direito não é fruto somente de uma pretensa influência do Common Law, como vários autores afirmam ao vincular a uma visão empirista tipicamente desse sistema; há sim, por outro lado, raízes na própria experiência jurídica do sistema romano-germânico que levam a tal valorização do caso, principalmente a partir da construção romana.

    Full Text Available Results of fundamental and applied studies of V. N. Sukachev Institute of Forest Russian Academy of Sciences, Siberian Branch and the Research Institute for Agrarian Problems of Khakassia, Federal Agency of Scientific Organizations of Russia in soil deflation control using management, also agrotechnological and agroafforestation measures, have been given in this scientific review. These activities were undertaken for 55 years. It was established that an average annual humus loss on arable lands in the south of Central Siberia made 1.6 t per 1 ha in the result of soil erosion. The system of usage and protection of soils subjected to erosion has been considered which covers the net of forest shelter belts, strip planting of agricultural crops, application of soil protective farming equipment and fertilizing. In the result of complex studies of soils prone to erosion the following activities were worked out: the way for fertility increase of sandy-loam soils by deep application of organic fertilizers; the way for growing the Siberian larch shelter forests; the way for growing the shelter stands using diagonally- wide meshed construction; the way for growing stands on slope pastures; the technology for growing the two-row shelter forests with a wide row- spacing; ways for growing stands for cattle-breeding purpose; ways for growing massive Scots pine stands; principles of choice of trees and bushes for shelter forests; the main standards for evaluation of linear steppe stands in the south of Krasnoyarsk Krai, Khakass Republic and the Republic of Tyva; concept for growing a new generation of shelter forests ect. Protective forest stands established in the south of Central Siberia in the area more than 50 thousand ha are shown to give a new environmental effect resulting in an increase of soil fertility and crop capacity.

Para tanto, foram simulados valores fenotípicos com distribuição simétrica e com distribuição assimétrica à direita e à esquerda, com ou sem a presença de "outliers". A metodologia proposta foi aplicada a um conjunto de dados provenientes de um experimento com 92 genótipos de alfafa (Medicago sativa, avaliados em 20 ambientes, e comparada às metodologias de Eberhart & Russell e de regressão não paramétrica. A metodologia da RQ proporcionou resultados iguais ou superiores aos obtidos com as metodologias alternativas avaliadas. No entanto, a ocorrência de resultados discordantes entre as metodologias evidencia a importância de se avaliar a simetria na distribuição dos valores fenotípicos. Para distribuições simétricas, na presença de "outliers", deve-se utilizar a RQ com valor de quantil estimado (τ em 0,50; na ausência de "outliers", pode-se utilizar tanto a metodologia de Eberhart & Russell quanto a RQ (τ = 0,50. Para distribuições assimétricas, indica-se o uso da RQ com τ = 0,25, para assimetria à direita, e com τ = 0,75, para assimetria à esquerda, independentemente da presença de "outliers".

    The thermoelectric centrals of the combined cycle type (Brayton Cycle and Rankine Cycle) present a series of opportunities to increase the efficiency of the combined cycle or of the generated power. This paper shows the methodology for the performance of energy balances in a heat recuperator (H. R.), typically employed in the combined cycle stations operating in Mexico, for the assessment of the energy harnessing in the different sections conforming a H. R. The effect of the installation of evaporative coolers and/or an absorption cooling system at the gas turbine compressor intake on the steam generation in the heat recuperator, is evaluated. This extra generation of steam is quantified for its potential use in the same absorption refrigeration system. From the assessment, it follows up that the steam generation in the H.R. is inversely proportional to the ambient temperature and that, although the increased amount of steam generated can not be harnessed in total by the steam turbine, the remaining fraction is good enough to cover the heat demand for the operation of the refrigeration system.

    The weakness of small island electrical grids implies a handicap for the electrical generation with renewable energy sources. With the intention of maximizing the installation of photovoltaic generators in the Canary Islands, arises the need to develop a solar forecasting system that allows knowing in advance the amount of PV generated electricity that will be going into the grid, from the installed PV power plants installed in the island. The forecasting tools need to get feedback from real weather data in "real time" from remote weather stations. Nevertheless, the transference of this data to the calculation computer servers is very complicated with the old point to point telecommunication systems that, neither allow the transfer of data from several remote weather stations simultaneously nor high frequency of sampling of weather parameters due to slowness of the connection. This one project has developed a telecommunications infrastructure that allows sensorizadas remote stations, to send data of its sensors, once every minute and simultaneously, to the calculation server running the solar forecasting numerical models. For it, the Canary Islands Institute of Technology has added a sophisticated communications network to its 30 weather stations measuring irradiation at strategic sites, areas with high penetration of photovoltaic generation or that have potential to host in the future photovoltaic power plants connected to the grid. In each one of the stations, irradiance and temperature measurement instruments have been installed, over inclined silicon cell, global radiation on horizontal surface and room temperature. Mobile telephone devices have been installed and programmed in each one of the weather stations, which allow the transfer of their data taking advantage of the UMTS service offered by the local telephone operator. Every minute the computer server running the numerical weather forecasting models receives data inputs from 120 instruments distributed

By applying the notion of betweenness centrality to 28 worldwide metro systems, the main goal of this paper is to study the emergence of global trends in the evolution of centrality with network size and examine several individual systems in more detail. Betweenness was notably found to consistently become more evenly distributed with size (i.e. no "winner takes all" unlike other complex network properties. Two distinct regimes were also observed that are representative of their structure. Moreover, the share of betweenness was found to decrease in a power law with size (with exponent 1 for the average node, but the share of most central nodes decreases much slower than least central nodes (0.87 vs. 2.48. Finally the betweenness of individual stations in several systems were examined, which can be useful to locate stations where passengers can be redistributed to relieve pressure from overcrowded stations.

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

  10. Power station instrumentation

    International Nuclear Information System (INIS)

    Power stations are characterized by a wide variety of mechanical and electrical plant operating with structures, liquids and gases working at high pressures and temperatures and with large mass flows. The voltages and currents are also the highest that occur in most industries. In order to achieve maximum economy, the plant is operated with relatively small margins from conditions that can cause rapid plant damage, safety implications, and very high financial penalties. In common with other process industries, power stations depend heavily on control and instrumentation. These systems have become particularly significant, in the cost-conscious privatized environment, for providing the means to implement the automation implicit in maintaining safety standards, improving generation efficiency and reducing operating manpower costs. This book is for professional instrumentation engineers who need to known about their use in power stations and power station engineers requiring information about the principles and choice of instrumentation available. There are 8 chapters; chapter 4 on instrumentation for nuclear steam supply systems is indexed separately. (Author)

Brief details are given of station layout and principle design parameters. Safety features are described and a brief account is given of scheduling, construction and commissioning. Operating performance is discussed. Turbine generators and auxiliaries, and the feedwater system contributed to more than half the outage time. An illustration is given of incorrect rolling operation which caused cracks in the Zr-Nb pressure tube, resulting in several leaks in Unit 3. Heavy water losses were low, as were radioactive releases. Economic features are discussed in terms of capital cost operating costs and total unit energy cost. Reference is made to Pickering B which is a 4 x 540MW(e) station, a mirror image of Pickering A, and scheduled for operation in 1980. The interest in the Pickering station being shown in many areas of the world is attributed to its simplicity, low fuel cycle cost, versatile pressure tube design features which meet requirements for safety, reliability, and maintainability.

    Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present.

  1. A Central Brazil GT5 Event

    2013-05-01

    Ground-truth (GT) events, accurately located with a precision of 5 km (GT5 event) and associated travel times to regional stations are important in developing precise velocity models. The low Brazilian seismicity, with only three continental earthquakes of magnitude five in the last three decades, and the low number of seismic stations explain the difficulty to detect events at regional distances. In the world maps of GT events, Brazil appears almost empty. In Stable Continental Interiors, like Brazil, it is difficult to find an event fulfilling all the GT5 prerequisites, particularly in respect with the number of picked phases and azimuthal gaps. Recently PTS-CTBTO has organized meeting and workshops to encourage seismologists from South and Central America to cooperate with the work of identifying GT5 events in these countries, with a goal of developing a 3-dimentional velocity model for this part of the globe not covered yet like Europe and North America. As a result we studied a recent magnitude 5 event in Central Brazil detected by few regional stations. Aftershock studies with local stations, showed a fault 5 km long. Taking the mainshock epicenter as the center of fault the maximum error would be minimal, 2.5 km, assuming the events were located with zero uncertainty. The parameters depth and origin time source were precisely determined using correlations between waveforms of six events and stations corrections. The event magnitudes range from 3.5 to 5.0 (mainshock, taken as reference event) recorded by regional and local stations. Events recorded at local and regional stations were used to determine the regional station corrections. These events were located only with data from local stations, assigning to the regional stations P and S phases zero weight in order to determine residuals for each regional stations used. The stations corrections were taken as the average of the residuals at each station. Precise pickings of P and S phases for the mainshock

    This paper is a proposal for the systematization of the process of bioclimatic design, particularly in its analytical stage. It is based on the proposals of the classic researchers such as: Olgyay, Givoni and Szokolay, but also in new contributions like those of Yeang. Nevertheless, it is about a methodology adapted to the specific requirements of teaching and research that are carried out in the Bioclimatic Design Laboratory of the Universidad Autonoma Metropolitana, Azcapotzalco Unit. What is presented here is a part of a very ample research project that intends to develop or to structure a design methodology that incorporates the environmental variables related to man and architecture: of course, with the objective of facilitating the designer work so that the final architectonic product has a more harmonic response to the environment, offers conditions of integral well- being to its occupants and be is efficient in the handling of the resources. It also looks for the definition of the necessary analysis, design and evaluation tools, necessary in order that the application of the methodology is clear, simple and can be carried out by any designer, even if he does not have a wide knowledge of bioclimatic design.

    Bergey, M.

    1997-12-01

    This paper discusses the concept of battery charging stations (BCSs), designed to service rural owners of battery power sources. Many such power sources now are transported to urban areas for recharging. A BCS provides the opportunity to locate these facilities closer to the user, is often powered by renewable sources, or hybrid systems, takes advantage of economies of scale, and has the potential to provide lower cost of service, better service, and better cost recovery than other rural electrification programs. Typical systems discussed can service 200 to 1200 people, and consist of stations powered by photovoltaics, wind/PV, wind/diesel, or diesel only. Examples of installed systems are presented, followed by cost figures, economic analysis, and typical system design and performance numbers.

    Full Text Available Public transport is one of the facilities available in Malaysia. Overwhelming demand from the community has demanded public transport as an alternative for some people to do their daily activities. The increasing of Malaysian population brought many problems to the environment especially traffic congestion problem. The Government spends a lot of money to overcome this problem [10]. Public transport has been upgraded to ensure user comfort. Most people in the city are more interested in using railway transport as traffic congestion and travel time accuracy is better than other public transport [1, 5]. To influence public demand, the facilities available at the train station should be complete [3, 5]. The choice of location for the study are Batu Gajah station (station 1 and Kluang station (station 2 for rural services while Bandar Tasik Selatan station (station 3 and KL Central station (station 4 for urban services. The results of this study showed that, based on data and information obtained from field survey work and the feedback questionnaires from users, basic facilities at railway stations surveyed for urban and rural services can be identified and listed. An analysis of the status of the facilities at railway stations can be established through the safety of passengers and observations in the field. The facilities available at the urban service station are more complete than in rural service station. Facilities at railway station should be improved to attract people using the facilities.

    O objetivo deste trabalho foi determinar o perfil físico-químico da aguardente de cana-de-açúcar produzida por diferentes metodologias de dupla destilação em alambique simples. Mosto fermentado de caldo de cana-deaçúcar foi destilado em alambique simples seguindo três metodologias de dupla destilação: a empregada para a produção de conhaque, a empregada na produção de uísque e a metodologia da proporção porcentual 10-80-10, referente aos volumes das frações “cabeça”, “coração” e “cauda” do destilado da segunda destilação. Para comparação, também foi produzida uma aguardente de cana-de-açúcar monodestilada. Os destilados foram analisados quimicamente quanto às concentrações de etanol, cobre, acidez volátil, furfural e hidroximetilfurfural, aldeídos, ésteres, metanol e álcoois superiores. As aguardentes de cana-de-açúcar foram também avaliadas sensorialmente quanto aos atributos de aroma, sabor e preferência. Comparada com a monodestilação, a dupla destilação melhorou a qualidade química das aguardentes, pois proporcionou redução das concentrações de cobre, de acidez volátil, de aldeídos, de ésteres, de metanol, de álcoois superiores e, consequentemente, do coeficiente de congêneres das aguardentes. As metodologias de dupla destilação baseadas na produção de conhaque e de uísque proporcionaram maior redução na concentração dos componentes secundários das aguardentes que a metodologia baseada na proporção 10-80-10. A dupla destilação melhorou também a qualidade sensorial das aguardentes, pois, independentemente da metodologia empregada, as aguardentes produzidas por dupla destilação obtiveram maior aceitação sensorial que a aguardente monodestilada. Dentre as aguardentes duplamente destiladas, a produzida segundo a metodologia do uísque obteve as maiores notas dos provadores quanto aos parâmetros de aroma e sabor e também foi a mais preferida.

    In this occasion, a methodology is presented that carries out an integral energy evaluation of fossil fuel power plants units (FFPPU) with the purpose of determining the root of the significant decrements of power produced soon after the annual maintenance service. This proposal, besides identifying the origin of the energy efficiency problems, offers information about the contributions of each one of the involved equipment in the total decrement of the unit. With this methodology, the maintenance focuses in the equipment that contributes to the greater energy loss. This document presents such methodology along with its application in a real case, results and necessary remedial actions, demonstrating that its application offers bases for the investment in corrective measures. [Spanish] En esta ocasion se presenta una metodologia que efectua una evaluacion energetica integral de las unidades de centrales termoelectricas (UCT) con el fin de determinar la raiz de los decrementos de potencia significativos producidos luego del servicio anual de mantenimiento.

    This is a view of the Russian Mir Space Station photographed by a crewmember of the fifth Shuttle/Mir docking mission, STS-81. The image shows: upper center - Progress supply vehicle, Kvant-1 module, and Core module; center left - Priroda module; center right - Spektr module; bottom left - Kvant-2 module; bottom center - Soyuz; and bottom right - Kristall module and Docking module. The Progress was an unmarned, automated version of the Soyuz crew transfer vehicle, designed to resupply the Mir. The Kvant-1 provided research in the physics of galaxies, quasars, and neutron stars, by measuring electromagnetic spectra and x-ray emissions. The Core module served as the heart of the space station and contained the primary living and working areas, life support, and power, as well as the main computer, communications, and control equipment. Priroda's main purpose was Earth remote sensing. The Spektr module provided Earth observation. It also supported research into biotechnology, life sciences, materials science, and space technologies. American astronauts used the Spektr as their living quarters. Kvant-2 was a scientific and airlock module, providing biological research, Earth observations, and EVA (extravehicular activity) capability. The Soyuz typically ferried three crewmembers to and from the Mir. A main purpose of the Kristall module was to develop biological and materials production technologies in the space environment. The Docking module made it possible for the Space Shuttle to dock easily with the Mir. The journey of the 15-year-old Russian Mir Space Station ended March 23, 2001, as the Mir re-entered the Earth's atmosphere and fell into the south Pacific Ocean.

  3. Submerged AUV Charging Station

    Jones, Jack A.; Chao, Yi; Curtin, Thomas

    2014-01-01

    Autonomous Underwater Vehicles (AUVs) are becoming increasingly important for military surveillance and mine detection. Most AUVs are battery powered and have limited lifetimes of a few days to a few weeks. This greatly limits the distance that AUVs can travel underwater. Using a series of submerged AUV charging stations, AUVs could travel a limited distance to the next charging station, recharge its batteries, and continue to the next charging station, thus traveling great distances in a relatively short time, similar to the Old West “Pony Express.” One solution is to use temperature differences at various depths in the ocean to produce electricity, which is then stored in a submerged battery. It is preferred to have the upper buoy submerged a reasonable distance below the surface, so as not to be seen from above and not to be inadvertently destroyed by storms or ocean going vessels. In a previous invention, a phase change material (PCM) is melted (expanded) at warm temperatures, for example, 15 °C, and frozen (contracted) at cooler temperatures, for example, 8 °C. Tubes containing the PCM, which could be paraffin such as pentadecane, would be inserted into a container filled with hydraulic oil. When the PCM is melted (expanded), it pushes the oil out into a container that is pressurized to about 3,000 psi (approx equals 20.7 MPa). When a valve is opened, the high-pressure oil passes through a hydraulic motor, which turns a generator and charges a battery. The low-pressure oil is finally reabsorbed into the PCM canister when the PCM tubes are frozen (contracted). Some of the electricity produced could be used to control an external bladder or a motor to the tether line, such that depth cycling is continued for a very long period of time. Alternatively, after the electricity is generated by the hydraulic motor, the exiting low-pressure oil from the hydraulic motor could be vented directly to an external bladder on the AUV, such that filling of the bladder

    The Space Shuttle Furnace Facility (SSFF) is the modular, multi-user scientific instrumentation for conducting materials research in the reduced gravity environment of the International Space Station. The facility is divided into the Core System and two Instrument Racks. The core system provides the common electrical and mechanical support equipment required to operate experiment modules (EMs). The EMs are investigator unique furnaces or apparatus designed to accomplish specific science investigations. Investigations are peer selected every two years from proposals submitted in response to National Aeronautics and Space Administration Research Announcements. The SSFF Core systems are designed to accommodate an envelope of eight types of experiment modules. The first two modules to be developed for the first instrument rack include a high temperature gradient furnace with quench, and a low temperature gradient furnace. A new EM is planned to be developed every two years.

    This paper describes research concerning the effects of human engineering design at local control stations (i.e., operator interfaces located outside the control room) on human performance and plant safety. The research considered both multifunction panels (e.g. remote shutdown panels) as well as single-function interfaces (e.g., valves, breakers, gauges, etc.). Changes in performance shaping factors associated with variations in human engineering at LCSs were estimated based on expert opinion. By means of a scaling procedure, these estimates were used to modify the human error probabilities in a PRA model, which was then employed to generate estimates of plant risk and scoping-level value/impact ratios for various human engineering upgrades. Recent documentation of human engineering deficiencies at single-function LCSs was also reviewed, and an assessment of the current status of LCSs with respect to human engineering was conducted.

    Full Text Available A metodologia de Shigeo Shingo (SMED - single minute exchange of die foi publicada pela primeira vez no Ocidente em 1985, e é referência principal quando se trata de redução dos tempos de setup de máquinas. A metodologia enfatiza a separação e a transferência de elementos do setup interno para o setup externo. As diversas aplicações industriais e os artigos existentes indicam a relevância do tema e da metodologia. Este artigo propõe-se a analisar criticamente o SMED revelando as lacunas da metodologia. Particularmente, discutem-se os problemas associados aos períodos de desaceleração e aceleração relacionados às atividades de setup, verificando-se que a separação e a conversão de tarefas não são suficientes. Para tanto, apresenta-se um estudo de caso em uma linha de produção.Shingo ´s SMED (single minute exchange of die methodology was first published in the West in 1985 and is today widely used by companies to reduce changeover times. The methodology, which emphasizes the separation and conversion of internal setup to external setup, is likewise favourably viewed within academia. This article analyzes SMED, indicates some gaps in the methodology and proposes how potential shortcomings might be overcome. In particular it discusses problems associated with both the run-down and run-up phases of a changeover, and describes how an over-reliance on techniques to separate and convert changeover tasks can be misplaced.

    In this article a thermal-environmental study is presented in order to evaluate the energy demand in the Morelos state. From collected climatologic data in seven automatic weather stations a comparative diagnosis by the application of two methodologies is realized, such as the one of the Degrees-day and the transitory thermal simulation of TRNSYS to determine the energy demand in traditional dwellings of social interest located in different regions of the State. In the methodology of the degrees-day the ambient temperature for two seasons of the year is used (rainy and dry) and the energy demand for the comfort in the Morelos State is evaluated. For the thermal simulation with the TRNSYS the climatic data obtained in monthly averages is used to determine the thermal loads of the house and the energy requirements in the different regions of the State. The results of the energy demand obtained by both methodologies for the municipality of Jiutepec and a statistic analysis of the existing relation between the degrees-day of cooling and the energy demand for cooling that the dynamic simulations deliver are presented.

  13. Accelerated GLAS exposure station

    International Nuclear Information System (INIS)

    The Geoscience Laser Altimeter System (GLAS) is being developed by NASA/GSFC to measure the dynamics of the ice sheet mass balance, land, and cloud and atmospheric properties. An instrument altimetric resolution of 10 cm per shot is required. The laser transmitter will be a diode pumped, Q-switched, Nd:YAG laser producing 1064 nm, 100 mJ, 4 ns pulses at 40 Hz repetition rate in a TEM∞ mode. A minimum lifetime goal of 2 billion shots is required per laser transmitter. The performance of the GLAS laser can be limited by physical damage to the optical components caused by the interaction of intense laser energy with the optical coatings and substrates. Very little data exists describing the effects of long duration laser exposure, of 4 ns pulses, on an optical component. An Accelerated GLAS Exposure Station (AGES) is being developed which will autonomously operate and monitor the GLAS laser at an accelerated rate of 500 Hz. The effects of a large number of laser shots will be recorded. Parameters to be monitored include: laser power, pulsewidth, beam size, laser diode drive current and power, Q-switch drive voltage, temperature, and humidity. For comparison, one set of AGES-sister optical components will be used in the non-accelerated GLAS laser and another will be evaluated by a commercial optical damage test facility

  17. Seismometer array station processors

    International Nuclear Information System (INIS)

    A description is given of the design, construction and initial testing of two types of Seismometer Array Station Processor (SASP), one to work with data stored on magnetic tape in analogue form, the other with data in digital form. The purpose of a SASP is to detect the short period P waves recorded by a UK-type array of 20 seismometers and to edit these on to a a digital library tape or disc. The edited data are then processed to obtain a rough location for the source and to produce seismograms (after optimum processing) for analysis by a seismologist. SASPs are an important component in the scheme for monitoring underground explosions advocated by the UK in the Conference of the Committee on Disarmament. With digital input a SASP can operate at 30 times real time using a linear detection process and at 20 times real time using the log detector of Weichert. Although the log detector is slower, it has the advantage over the linear detector that signals with lower signal-to-noise ratio can be detected and spurious large amplitudes are less likely to produce a detection. It is recommended, therefore, that where possible array data should be recorded in digital form for input to a SASP and that the log detector of Weichert be used. Trial runs show that a SASP is capable of detecting signals down to signal-to-noise ratios of about two with very few false detections, and at mid-continental array sites it should be capable of detecting most, if not all, the signals with magnitude above msub(b) 4.5; the UK argues that, given a suitable network, it is realistic to hope that sources of this magnitude and above can be detected and identified by seismological means alone.

    2001-06-01

    In the present paper a regional estimation model of the synthetic hydrographs for the analysis of flood protection problems is proposed. The method is based on the regional estimation of both the flow duration reduction curve and the temporal location of the peak value in each duration. For the estimation of the reduction curve different models of stochastic and empirical derivation have been considered from literature, giving for two of these models regional estimation formulas in dependence on the geomorphologic characteristics of the river basins. To this end the historical flood waves recorded in 14 gauging stations of Mid-Northern Italy, mainly belonging to Po and Arno basins have been employed. The relation expressing the temporal location of the peak value in each duration has been obtained interpolating the experimental behaviours after standardization of the duration by the temporal scaling factor of the model adopted for the reduction curve. The synthetic hydrographs obtained from the regionalization procedure have been validated through the comparison with the corresponding ones coming from the direct statistical analysis of the historical flood waves for the gauging stations considered in the calibration process. [Italian] Nella presente memoria viene proposta una metodologia di stima indiretta degli idrogrammi sintetici per lo studio di problemi di difesa idraulica del territorio. Essa si basa sulla stima regionale della legge di riduzione dei colmi di piena e della posizione del picco all'interno di ciascuna durata. Per la determinazione della curva di riduzione sono stati esaminati diversi modelli a base stocastica o empirica proposti in letteratura, fornendo per due di essi formule di stima regionale dei parametri in funzione delle caratteristiche morfometriche dei bacini. A tale scopo sono state utilizzate le onde di piena registrate in 14 stazioni idrometrografiche dell'Italia Centrosettentrionale, apaprtenenti in prevalenza al bacino

    Full Text Available Senna alata, mais conhecida como mata-pasto na região Norte do Brasil, é uma planta utilizada pela medicina popular em várias partes do mundo e considerada espécie problemática em pastagens do Estado do Pará. No presente estudo, compararam-se duas metodologias distintas para a determinação das principais classes de constituintes potenciais aleloquímicos das diferentes frações (caules, flores, folhas, raízes, sementes e vagens de S. alata. O material vegetal foi seco e sofreu extração exaustiva com solvente hidrometanólico, para obtenção dos extratos brutos; uma pequena parte dele foi solubilizada em metanol para obtenção das soluções utilizadas nos testes fitoquímicos. As metodologias utilizadas foram: testes por cromatografia em camada delgada (CCD para determinação do perfil cromatográfico qualitativo; e ensaios para detecção preliminar dos diferentes constituintes químicos, com base na extração destes com solventes apropriados e na aplicação de testes de coloração. Os resultados em ambos os métodos demonstraram pouca semelhança, sendo o CCD o mais simples, barato, rápido e adequado para análise preliminar de compostos químicos derivados de plantas, embora seja um método qualitativo. Este método foi mais sensível para a detecção de flavonoides, porém, para detecção de alcaloides, o reativo de Bouchardat foi mais sensível do que o de Dragendorff, assim como o hidróxido de amônia 10% foi mais sensível às antraquinonas do que o hidróxido de potássio. O estudo comprovou a alta diversidade de compostos químicos presentes em Senna alata, justificando sua ampla utilização na medicina popular e indicando ainda o potencial alelopático para a sua utilização.Senna alata, known as mata-pasto in northern Brazil, is a plant used in popular medicine in several parts of the world, and considered harmful to pastures in the state of Pará.

    Full Text Available Devido à dificuldade de observação, quantificação e interpretação de sistemas radiculares, o estado da arte do conhecimento científico nesta área está aquém do desejável. Estas dificuldades tornam a análise e a interpretação da arquitetura de sistemas radiculares praticamente impossíveis de serem realizadas pela estatística tradicional, fazendo com que a modelagem matemática seja uma abordagem atrativa. Utilizou-se neste estudo plantas de soja, visto que a maioria dos trabalhos de pesquisa sobre a estrutura e funcionamento de sistemas radiculares de culturas comerciais tem sido realizada com um pequeno número de espécies, com ênfase nas monocotiledôneas, sendo muito poucos aqueles com dicotiledôneas herbáceas e espécies arbóreas. Estudou-se a influência da concentração de fósforo, nutriente freqüentemente deficiente nos solos brasileiros, sobre a arquitetura do sistema radicular da soja. A modelagem matemática apresentou-se como uma promissora metodologia de análise de dados de sistemas radiculares, possibilitando uma adequada visualização de diferentes estratégias adaptativas da planta, conforme refletidas pelas diferentes arquiteturas radiculares produzidas em cada condição.

  3. Waste management and environmental issues at Callide B Power Station

    International Nuclear Information System (INIS)

    Callide B is a coal-fired power station located east of Biloela in the Callide Valley of Central Queensland. To protect the Callide Valley groundwater, a zero waste-water discharge concept was adopted for the power station. This strategy is possible because waste-water volumes are minimized through natural evaporation, is re-used for ash transport and remaining wastes (mainly ash and water) are held behind a clay-cored earth dam 3.2 km in length. This paper describes the environmental monitoring programs, dam surveillance and waste management adopted to maintain the quality of the Callide Valley resource. Groundwater quality downstream of the power station site is considered good to marginal. It is used extensively as a source of irrigation water for agriculture and also supplies 40 percent of Biloela's town water requirements. (author). 8 figs., 17 refs

  12. Analysis of the ambient seismic noise at Bulgarian seismic stations

    Science.gov (United States)

    Dimitrova, Liliya; Nikolova, Svetlana

    2010-05-01

    Modernization of Bulgarian National Seismological Network has been performed during a month in 2005. Broadband seismometers and 24-bits digital acquisition systems with dynamic range more than 132dB type DAS130-01 produced by RefTek Inc. were installed at the seismic stations from the existing analog network. In the present study the ambient seismic noise at Bulgarian National Digital Seismological Network (BNDSN) stations is evaluated. In order to compare the performance of the network against international standards the detail analysis of the seismic noise was performed using software and models that are applied in the international practice. The method of McNamara and Bulland was applied and the software code PDFSA was used to determine power spectral density function (PSD) of the background noise and to evaluate the probability density function (PDF). The levels of the ambient seismic noise were determined and the full range of the factors influencing the quality of the data and the performance of a seismic station was analyzed. The estimated PSD functions were compared against two models for high (NHNM) and low (NLNM) noise that are widely used in seismological practice for seismic station monitoring qualities assessment. The mode PDF are used to prepare annual, seasonal, diurnal and frequency analyses of the noise levels at BNDSN stations. The annual analysis shows that the noise levels at the Northern Bulgarian stations are higher than the ones at Central and Southern stations for the microseisms' periods (1sec -7sec). It is well observable at SS PRV and PSN located near Black sea. This is due to the different geological conditions of the seismic stations as well. For the periods of "cultural" noise the power distribution depends on the type of noise sources and as a rule is related to human activities at or near the Earth surface. Seismic stations MPE, VTS and MMB have least mode noise levels and the noisiest stations are PGB, PVL и JMB. The seasonal

  13. Tidal currents measured near Sizewell Power Station

    International Nuclear Information System (INIS)

    During the latter half of 1975 the Central Electricity Generating Board (CEGB) commissioned a survey of water temperatures and currents in the sea near Sizewell Power Station, which is located on the coast of the southern North Sea some 150 km north-east of London. The survey was performed in coastal waters up to 5 km offshore and spanning an area of about 50 km2, to assist in an estimation of the marine dispersion of heat released with the cooling water discharge from the power station. Variations in time and space of the residual tidal movements are presented which provide the mechanism for bulk transport of water, and therefore of heat or other contaminants, from the area. It is shown that these variations can be considerable, and that this has important implications for far-field models of cooling water discharges. The results of harmonic analysis of the tidal velocity are used in two ways- first, the variation of the current with depth is discussed and the implications for the mid-field mixing of cooling water are brought out- second, the significance of reflections from the coast is highlighted by splitting the tidal wave into progressive and standing components.

  14. Railway Station Role in Composing Urban Conflicts

    2011-12-01

    Full Text Available Despite railway infrastructure was the structural framework on which modern European States were developed, contributing to unify territories and to the establishment of Nations, right from the beginning, the relationship between railway and city has been characterized by physical, functional and social conflicts, mainly because of a lack of integration between infrastructural and urban policies, which have been produced strong conflicts during decades. These critical situations have concentrated on the railway stations surrounding areas, which have started symbolizing the main conflicts that are taking place inside the cities.Similarly to what happened in the XIX century, today railway is a strategic infrastructure for the European territory development, thanks to the introduction of high speed transport systems and the promotion of rail transport as a more sustainable transportation system, which can quickly connect metropolitan central areas, more and more impenetrable by private vehicles, and key functions centres for the contemporary urban systems.In this framework, railway stations are becoming public places representing a complex society which is more and more dedicated to motion; thus they offer an unmissable chance not only to carry out urban development and spatial cohesion policies, but also to compose old tensions caused by the sharing of physical space, which is more and more scarce and valuable, and by ghettoization phenomena which have been produced at local scale, between rail infrastructure and the surrounding urban context. Today, such conflicts are growing and they are involving many actors who express a lot of different interests, needs and expectations, relating to the station areas’ destiny.Starting from the analysis of some conflicting situations between rail stations and the surrounding areas which have took place until today, this paper investigates some recent renewal interventions on Italian and European main railway

    International Nuclear Information System (INIS)

    This leaflet describes the Miksova water power station. The Miksova water power station is part of the second derived cascade of hydro power stations on the river Vah. It was built at the end of a huge development in Slovak hydro-energy in the late 1950's and the beginning of the 1960's. It is the second water power station on this derived cascade, which is situated downstream the Hricov reservoir and water power station. At the power station, three turbine sets with vertical Kaplan turbines are installed with a total power output of 3 x 31.2 = 93.6 MW. With this power output the Miksova water power station (Miksova I) was the biggest water power station in the Slovak Republic until the construction of Pumping water power station Liptovska Mara. And it is still the biggest channel water power station on the Vah so far. It was put into operation during the period 1963 to 1965. There are three turbine sets with Kaplan turbines from CKD Blansko, with a synchronous hydro-alternator installed in the power station. Their installed capacity is 93.6 MW in total and the projected annual production of electrical energy is 207 GWh. The turbines are fi ve-bladed (on the Hricov and Povazska Bystrica water power stations they are four-bladed) and the impeller wheel has a diameter of 4800 mm. They are designed for extension of the head from 24.1 to 22.21 m and each of them has an absorption capacity of 134 m3.s-1 nd a nominal operating speed of 2.08 m3.s-1, runaway speed 4.9 m3.s-1. Each synchronous hydro-alternator has a maximum power output of 31.2 MW, a nominal voltage of 10.5 kV and power factor cos φ of 0.8. Power from the power station is led out through 110 kV switchgear. The water power station operates under automatic turbine mode of operation with remote indication and control from the Dispatch Centre at Vodne elektrarne, in Trencin. From start of operation until the end of 2003 all three turbine sets operated for a total of 450,500 running hours and the Miksova water

  14. Space Station Freedom as an engineering experiment station: An overview

    Science.gov (United States)

    Rose, M. Frank

    1992-01-01

    In this presentation, the premise that Space Station Freedom has great utility as an engineering experiment station will be explored. There are several modes in which it can be used for this purpose. The most obvious are space qualification, process development, in space satellite repair, and materials engineering. The range of engineering experiments which can be done at Space Station Freedom run the gamut from small process oriented experiments to full exploratory development models. A sampling of typical engineering experiments are discussed in this session. First and foremost, Space Station Freedom is an elaborate experiment itself, which, if properly instrumented, will provide engineering guidelines for even larger structures which must surely be built if humankind is truly 'outward bound.' Secondly, there is the test, evaluation and space qualification of advanced electric thruster concepts, advanced power technology and protective coatings which must of necessity be tested in the vacuum of space. The current approach to testing these technologies is to do exhaustive laboratory simulation followed by shuttle or unmanned flights. Third, the advanced development models of life support systems intended for future space stations, manned mars missions, and lunar colonies can be tested for operation in a low gravity environment. Fourth, it will be necessary to develop new protective coatings, establish construction techniques, evaluate new materials to be used in the upgrading and repair of Space Station Freedom. Finally, the industrial sector, if it is ever to build facilities for the production of commercial products, must have all the engineering aspects of the process evaluated in space prior to a commitment to such a facility.

    International Nuclear Information System (INIS)

    This paper discusses a number of the interesting experiences encountered at the Douglas Point Nuclear Power Station. Sufficient background with respect to the basic process, equipment location, and commissioning history is given so that those not familiar with the station may follow the remainder of the paper. Three commissioning philosophies followed in the commissioning of Canadian nuclear power stations are mentioned: (1) no ordinary water used for commissioning heavy-water systems: (2) fuelling machines used for initial fuel loading; (3) no portable steam-generating equipment for preliminary turbine-generator run up. Against this background the following experiences are mentioned: low power physics measurements; fuel channel replacement and faulty booster removal; heat transport pressure control; ion-exchange resin in the heat transport system; heat transport pumps; boiler level control; possible fretting of pressure tubes; turbine operation; heavy-water experience. The paper concludes by mentioning some important lessons learned from the experience to date and states confidence in the future of Douglas Point Generating Station, and future Canadian nuclear power stations.

  17. Reviewing nuclear power station achievement

    International Nuclear Information System (INIS)

    For measurement of nuclear power station achievement against original purchase the usual gross output figures are of little value since the term loosely covers many different definitions. An authentically designed output figure has been established which relates to net design output plus house load at full load. Based on these figures both cumulative and moving annual load factors are measured, the latter measuring the achievement over the last year, thus showing trends with time. Calculations have been carried out for all nuclear stations in the Western World with 150 MW(e) gross design output and above. From these are shown: moving annual load factor indicating relative station achievements for all the plants; cumulative load factors from which return of investment can be calculated; average moving annual load factors for the four types of system Magnox, PWR, HWR, and BWR; and a relative comparison of achievement by country in a few cases.

    Full Text Available The last Hungarian repeat station survey was completed between October 2010 and February 2011. Declination, inclination and the total field were observed using one-axial DMI fluxgate magnetometer mounted on Zeiss20A theodolite and GSM 19 Overhauser magnetometer. The magnetic elements of the sites were reduced to the epoch of 2010.5 on the basis of the continuous recordings of Tihany Geophysical Observatory. In stations located far from the reference observatory, the observations were carried out in the morning and afternoon in order to decrease the effect of the distant temporal correction. To further increase the accuracy, on-site dIdD variometer has also been installed near the Aggtelek station, in the Baradla cave, during the survey of the easternmost sites. The paper presents the technical details and the results of our last campaign. The improvement of the accuracy of the temporal reduction by the use of the local variometer is also reported.

    Science.gov (United States)

    Haggren, Henrik G. A.

    1992-03-01

    Photogrammetric stations are used for vision based dynamic control of 3-D related phenomena. The vision sensors are fixed solid-state cameras which are permanently mounted and set up for a specific control task. The on-site calibration of the station allows the continuous processing of the 3-D space coordinates for all object points according to their actual 2-D image locations For automated control processes the object points are targeted using predefined templates extracted from the perspective images. The precision of an object point measured by the station is better than 1:10,000 of the object volume in all three coordinates. The vision application presented here is the locating of car bodies in the 3-D space of a robotic sealing cell.

Os Jogos de Oposição constituem um fim em si mesmo - a atividade lúdica não demanda metas extrínsecas, muito ao contrario, representa mais o desfrutar de meios, divertir-se com sua participação e superar-se. Aqui temos um paradoxo: o jogo é um fim, entretanto o utilizamos como conteúdo educativo. Ao mesmo tempo a solução está na análises dos participantes, que encontram o jogo como um fim e nós, educadores, os utilizamos como instrumento de aprendizagem. Estes conteúdos metodológicos foram trabalhados pelos alunos de Licenciatura em Educação Física, da Universidade Federal do Paraná (UFPR no Brasil e também foram experimentados em diversas escolas públicas de Curitiba, Paraná, com êxito total.Palavras Chave: Jogos, Oposição, Esportes de Combate

    In response to President Reagan's directive to NASA to develop a permanent marned Space Station within a decade, part of the State of the Union message to Congress on January 25, 1984, NASA and the Administration adopted a phased approach to Station development. This approach provided an initial capability at reduced costs, to be followed by an enhanced Space Station capability in the future. This illustration depicts the baseline configuration, which features a 110-meter-long horizontal boom with four pressurized modules attached in the middle. Located at each end are four photovoltaic arrays generating a total of 75-kW of power. Two attachment points for external payloads are provided along this boom. The four pressurized modules include the following: A laboratory and habitation module provided by the United States; two additional laboratories, one each provided by the European Space Agency (ESA) and Japan; and an ESA-provided Man-Tended Free Flyer, a pressurized module capable of operations both attached to and separate from the Space Station core.

    2010-07-29

    The transition to hydrogen as a fuel source presents several challenges. One of the major hurdles is the cost-effective production of hydrogen in small quantities (less than 1MMscf/month). In the early demonstration phase, hydrogen can be provided by bulk distribution of liquid or compressed gas from central production plants; however, the next phase to fostering the hydrogen economy will likely include onsite generation and extensive pipeline networks to help effect a pervasive infrastructure. Providing inexpensive hydrogen at a fleet operator’s garage or local fueling station is a key enabling technology for direct hydrogen Fuel Cell Vehicles (FCVs). The objective of this project was to develop a comprehensive, turnkey, stand-alone, commercial hydrogen fueling station for FCVs with state-of-the-art technology that is cost-competitive with current hydrocarbon fuels. Such a station would promote the advent of the hydrogen fuel economy for buses, fleet vehicles, and ultimately personal vehicles. Air Products, partnering with the U.S. Department of Energy (DOE), The Pennsylvania State University, Harvest Energy Technology, and QuestAir, developed a turnkey hydrogen fueling station on the Penn State campus. Air Products aimed at designing a station that would have 65% overall station efficiency, 82% PSA (pressure swing adsorption) efficiency, and the capability of producing hydrogen at $3.00/kg (gge) H2 at mass production rates. Air Products designed a fueling station at Penn State from the ground up. This project was implemented in three phases. The first phase evaluated the various technologies available in hydrogen generation, compression, storage, and gas dispensing. In the second phase, Air Products designed the components chosen from the technologies examined. Finally, phase three entailed a several-month period of data collection, full-scale operation, maintenance of the station, and optimization of system reliability and performance. Based on field data

  20. North Central Project: Environment act proposal

    International Nuclear Information System (INIS)

    Manitoba Hydro proposes to construct a power transmission and distribution line system to connect 12 northern Manitoba communities to the utility's central power grid. The purpose of this North Central Project (NCP) is to provide reliable and unrestricted electric service to remote communities now largely receiving limited diesel-generated power. The NCP is composed of a 138-kV transmission line running ca 350 km from the Kelsey Generating Station, ca 160 km of 25-kV distribution lines, new transformer stations at four communities, upgraded internal distribution systems within the communities, removal of existing diesel stations and restoration of the sites, modifications and additions to the Kelsey switchyard, and a communications system. The NCP is described in detail, including proposed line routes and transformer station locations, rationales for site and route selection, projected impacts on the environment and local societies, and consultations with the communities to be affected. Potential impacts are expected to be modest, with few unmitigable adverse impacts and a number of potentially significant positive benefits. Impact management measures are proposed to prevent or mitigate adverse effects and to create or enhance positive impacts such as local employment of native peoples. 49 figs., 1 tab

    Full Text Available Glucosyltransferase produced by strain Erwinia sp. is an intracellular enzyme that catalyzes the formation of isomaltulose from sucrose. Isomaltulose is a non-cariogenic reducing dissacharide commercially used in foods. Response surface methodology and 2³-factorial central composite design were employed to optimize a fermentation medium for the production of glucosyltransferase by Erwinia sp. in shaken flasks at 200 rpm and 30ºC. The three variables involved in this study were sugar cane molasses (SCM, corn steep liquor (CSL and yeast extract Prodex Lac SD (YEP. The statistical analysis of the results showed that, in the range studied, all the factors had a significant effect on glucosyltransferase production and the optimum medium composition for enzyme production was (in g l-1 SCM-100, CSL-60 and YEP-8, which lead to a glucosyltransferase activity of 6.65 U mL-1.A glicosiltransferase obtida pela linhagem Erwinia sp. é uma enzima intracelular que catalisa a conversão de sacarose em isomaltulose. A isomaltulose é um dissacarídeo redutor, não cariogênico e comercialmente utilizado em alimentos como substituto da sacarose. A metodologia de superfície de resposta e planejamento fatorial composto central-2³ foram utilizados para otimizar o meio de cultivo para a produção de glicosiltransferase de Erwinia sp. em frascos sob agitação a 200 rpm e 30ºC. As três variáveis independentes envolvidas no estudo foram o melaço de cana de açúcar, a água de maceração de milho e o extrato de levedura Prodex Lac SD. As análises estatísticas dos resultados mostraram que, dentro da faixa estudada das concentrações dos componentes de meio de cultivo, todas as variáveis apresentaram efeito significativo na produção de glicosiltransferase. O meio de cultivo otimizado foi composto de 100 gL-1 de melaço de cana de açúcar, 60 gL-1 de água de maceração de milho e 8 gL-1 de extrato de levedura Prodex Lac SD, apresentando atividade de

    resultados. A presente pesquisa teve como objeto de estudo a Fazenda Experimental da Prefeitura Municipal de Barretos-SP, onde foram coletados amostras em declividade de 2, 4, 7, 10, 13, 16 e 20% e com 5 repetições, totalizando 35 amostras. As amostras de solo foram submetidas a análises granulométricas por peneiramento e densimetria e os seus resultados comparados através de análise de variância. Os resultados obtidos apontam que a perda de argila ao longo do declive apresentou comportamento com tendência linear, tendo um aumento em média de 15% entre o primeiro, e último ponto. Foram constatadas diferenças entre as duas metodologias aplicadas, onde o método do densímetro obteve resultados mais precisos em relação ao do peneiramento. Os resultados indicaram, portanto, que o método da sedimentação tem maior precisão na quantificação das frações de areia, silte e argila, sendo a maior causa de divergência, a maneira como é feito o desagregamento em cada método.

    Full Text Available Receptores killer cell immunoglobulin-like (KIRs são moléculas localizadas na superfície de células natural killer (NK e em subpopulações de linfócitos T codificadas por genes do cromossomo 19q13.4. A interação entre receptores KIR e moléculas antígeno leucocitário humano (HLA de classe I determina se células NK exercerão ou não sua função citotóxica e/ou secretora de citocinas ou se esta será inibida. Este trabalho teve por finalidade otimizar a metodologia para a genotipagem KIR, baseando-se nas condições descritas por Martin (2004. A técnica utilizada foi a reação em cadeia da polimerase com primers de sequência específica (PCR-SSP com iniciadores sintetizados pela Invitrogen® e visualização do produto amplificado em gel de agarose a 2% com brometo de etídio. Adaptações foram realizadas e a concentração de alguns reagentes foi alterada, como a do controle interno de 100 nM para 150 nM, iniciadores específicos senso e antissenso de KIR12.5/12.3, KIR13.5/13.3, KIR14.5/14.3, KIR22.5/22.3 e KIR36.5/36.3 de 500 nM para 750 nM e da solução de MgCl2 de 1,5 mM para 2 mM. As concentrações dos demais reagentes e temperaturas de amplificação foram mantidas. Nessas condições, o uso da Taq DNA polimerase recombinante (Invitrogen® foi satisfatório.

    Full Text Available Apesar da crise econômica global do final de 2008, a expectativa para o consumo de aço nos países do grupo dos BRICs - Brasil, Rússia, Índia e China - é de que haja um aumento significativo nas próximas décadas, em função de seu atual baixo consumo per capita. Como a abertura de novas minas para suprir o aumento da demanda do setor siderúrgico está limitada por questões ambientais, sociais, de mão-de-obra, energia e fornecimento de equipamentos, o aumento da produtividade de operações existentes será um fator essencial. Na indústria de mineração, métodos de estimativa têm sido usados há décadas na gestão de produtividade. As maiores dificuldades para a estimativa de produtividade de uma mina incluem a obtenção dos dados necessários e a complexidade da criação do modelo. No presente trabalho, apresenta-se o desenvolvimento de uma nova abordagem para a estimativa de produtividade de lavra a partir de regressões múltiplas com base em dados operacionais da mina. Essa abordagem integra a Metodologia de Estimativa e Gestão de Produtividade de Minas (MEGPM, cuja aplicação se justifica pela obtenção de ganhos em eficiência, a partir da eliminação das perdas no fluxo produtivo. Foram garantidos ganhos consideráveis com diminuição das diferenças entre os ICDs das turmas operacionais. As variáveis operacionais foram obtidas diretamente da base de dados do sistema de gerenciamento de operações e o desenvolvimento do modelo se deu de forma simples, de fácil aplicação com boa correlação entre os valores de produtividade estimados e obtidos. As etapas que compõem o desenvolvimento desse modelo de gestão, bem como um estudo de caso, serão apresentadas nesse trabalho.Even with the financial crisis of 2008, the steel consumption forecast for the BRIC countries - Brazil, Russia, India and China - is for a significant increase over the next decades, due to their present low per-capita consumption level.

    2009-03-01

    Full Text Available Esse artigo apresenta uma metodologia para incorporação de incertezas à modelagem numérica pelo método dos elementos distintos em análises de confiabilidade estrutural de escavações em rocha. A metodologia foi desenvolvida levando em conta que os métodos de modelagem numérica normalmente empregados fornecem resultados pontuais, determinados a partir de parâmetros de entrada fixos, sem que sejam considerados seus respectivos erros. Entretanto a análise da estabilidade de estruturas em rocha envolve incertezas decorrentes da variabilidade inerente aos processos geológicos, da incerteza a respeito da hipótese de comportamento mecânico adotada e, também, das incertezas associadas aos parâmetros adotados na formulação do modelo numérico. Essas fontes de incerteza podem ser levadas em conta em modelos determinísticos simples, mas, na modelagem numérica, onde os resultados são de diversas naturezas, cabendo ao pesquisador analisá-los para obter suas conclusões, faz-se necessário o desenvolvimento de uma metodologia nova, baseada em simulações de Monte Carlo, com o emprego dos princípios da Lógica Paraconsistente, e que será apresentada na análise de um talude final de uma cava de mineração de grandes dimensões.A methodology for rock-excavation structural-reliability analysis that uses Distinct Element Method numerical models is presented. The methodology solves the problem of the conventional numerical models that supply only punctual results and use fixed input parameters, without considering its statistical errors. The analysis of rock-excavation stability must consider uncertainties from geological variability, from uncertainty in the choice of mechanical behaviour hypothesis, and from uncertainties in parameters adopted in numerical model construction. These uncertainties can be analyzed in simple deterministic models, but a new methodology was developed for numerical models with results of several natures. The

    Full Text Available A qualidade da análise granulométrica é imprescindível para a adequada classificação textural dos solos e enquadramento no Zoneamento Agroclimático. O objetivo deste trabalho foi avaliar metodologias de controle de qualidade das análises granulométricas. Foram coletadas amostras de solos com diferentes texturas, as quais foram analisadas por cinco laboratórios. O controle da qualidade foi realizado utilizando duas metodologias, uma proposta pelo Instituto Agronômico de Campinas (IAC e a outra pela Rede Oficial de Laboratórios de Análise de Solo e de Tecido Vegetal dos Estados do RS e SC (ROLAS. Verificou-se maior número de inconformidades para as frações argila e silte, independentemente do método, sendo que o método da ROLAS apresentou maior número de inconformidades (76% das amostras, principalmente para amostras com teores mais elevados dessas frações. A metodologia da ROLAS com utilização da mediana é mais rigorosa no controle da qualidade das análises.The quality of particle size analysis is essential for correct soil textural classification and defining the Brazilian Agroclimatic Zoning. The objectives were to evaluate methods of particle size analysis and develop a spreadsheet for use in quality control analyzes. We collected 50 soil samples with different particle size distribution, in RS and SC states of Brazil, which were analyzed by five laboratories in the two states that perform the soil particle size analysis using two methods: one proposed by the Campinas Agronomic Institute (IAC and the other by the Network of Soil and Plant Tissue Analysis Laboratories of the states of RS and SC (ROLAS. A greater number of disparities were observed for the clay and sand fractions regardless of the method. The ROLAS method had a higher number of mismatches (76% of samples, especially for samples with higher contents of those two fractions. The use of the median value in the ROLAS methodology is more rigorous in analysis

  20. Pumps for nuclear power stations

    International Nuclear Information System (INIS)

    16 nuclear power plants are in commercial operation in Japan, and nuclear power generation holds the most important position among various substitute energies. Hereafter also, it is expected that the construction of nuclear power stations will continue because other advantageous energy sources are not found. In this paper, the outline of the pumps used for BWR plants is described. Nuclear power stations tend to be large scale to reduce the construction cost per unit power output, therefore the pumps used are those of large capacity. The conditions to be taken in consideration are high temperature, high pressure, radioactive fluids, high reliability, hydrodynamic performances, aseismatic design, relevant laws and regulations, and quality assurance. Pumps are used for reactor recirculation system, control rod driving hydraulic system, boric acid solution injecting system, reactor coolant purifying system, fuel pool cooling and purifying system, residual heat removing system, low pressure and high pressure core spraying systems, and reactor isolation cooling system, for condensate, feed water, drain and circulating water systems of turbines, for fresh water, sea water, make-up water and fire fighting services, and for radioactive waste treating system. The problems of the pumps used for nuclear power stations are described, for example, the requirement of high reliability, the measures to radioactivity and the aseismatic design. (Kako, I.)

    1991-01-01

    This panel discussion convened in Houston, Texas, at the Lunar and Planetary Institute, on November 6 to 8, 1989, to review NASA's plans for microbiology on Space Station Freedom. A panel of distinguished scientists reviewed, validated, and recommended revisions to NASA's proposed acceptability standards for air, water, and internal surfaces on board Freedom. Also reviewed were the proposed microbiology capabilities and monitoring plan, disinfection procedures, waste management, and clinical issues. In the opinion of this advisory panel, ensuring the health of the Freedom's crews requires a strong goal-oriented research effort to determine the potential effects of microorganisms on the crewmembers and on the physical environment of the station. Because there are very few data addressing the fundamental question of how microgravity influences microbial function, the panel recommended establishing a ground-based microbial model of Freedom, with subsequent evaluation using in-flight shuttle data. Sampling techniques and standards will be affected by both technological advances in microgravity-compatible instrumentation, and by changes in the microbial population over the life of the station.

    Full Text Available Design of an appropriate ventilation system is one of the main concerns in the construction of subways. In this paper, thermal comforts of side-platform stations are investigated by numerical methods. For the numerical simulation, grids are generated by structured methods and governing equations are discretized by finite volume methods. In the numerical simulation, second order upwind and second order central difference scheme are used to consider the convection and diffusion terms of momentum and energy equations, respectively. Results of this study show that in term of thermal comfort, region next to the hallway and the middle part of the platform is the worst zones of the station. In these zones, air velocity is very low (less than 0.5m/s and the air temperature reaches to 34°C which is more than its limit (Tmax≤32°C.

En el presente trabajo se aborda el problema del diagnostico de ubicacion de fallas electricas en sistemas de potencia, desde la perspectiva de los operadores de los centros de control de energia de una empresa electrica. El objetivo de este trabajo de tesis es describir una metodologia de analisis de operacion de protecciones como base para el desarrollo de un sistema de diagnostico de ubicacion de fallas, que permita estimar los posibles lugares de falla dentro del sistema asi como una justificacion de la operacion de las protecciones ante un disturbio como apoyo a los operadores de los Centros de Control de Energia. La metodologia esta disenada para utilizar distintos tipos de informacion, discreta, continua y controles. Sin embargo, en el desarrollo de la presente etapa de la metodologia propuesta se hace uso exclusivamente de la informacion de tipo discreta de los estados de interruptores y operacion de relevadores, asi como de la conectividad de los elementos de la red. La metodologia de analisis consiste en determinar el grupo de elementos donde pudo haber ocurrido la falla, utilizando las zonas de cobertura de las protecciones asociadas a los interruptores operados. Posteriormente, estas alternativas de falla se ordenan en forma descendentes de posibilidad utilizando indices de clasificacion y analisis basados en logica difusa.

Muitos desses equipamentos necessitam de um mapeamento prévio do alvo de interesse para sua utilização. O propósito deste trabalho foi a avaliação de uma metodologia prática para o mapeamento de plantas daninhas pelo contorno das reboleiras com um quadriciclo. Foram realizados dois mapeamentos em um mesmo campo agrícola, com quinze dias de intervalo. A metodologia aplicada para o mapeamento de plantas daninhas mostrou-se eficiente nas condições avaliadas. Foi possível a obtenção dos mapas de plantas daninhas com três níveis de infestação. Verificou-se a necessidade de um planejamento para a realização do mapeamento, levando-se em consideração a posterior aplicação localizada de defensivos.Several items of equipment able to realize site specific chemical application have been developed. Equipment for site specific chemical application needs a prescription map of the target area. The purpose of this work was to evaluate a practical method for weed mapping by driving over the patch contour with an All Terrain Vehicle (ATV. Two weed maps were created for the same agricultural field. The proposed method for weed mapping was considered efficient for the evaluated conditions. The weed maps obtained showed three infestations levels. An important conclusion obtained was that timing to perform the weed mapping is a very important factor to be considered for site specific chemical application.

Especificamente, podem ocorrer modificações metalúrgicas na ZAC (zona afetada pelo calor, levando a alterações microestruturais. Contudo esta é uma região de difícil estudo devido a sua pequena dimensão. Assim, a fim de superar esta limitação com relação ao estudo da ZAC, existem na literatura proposições de máquinas de simulação de ZAC, que fazem uso do efeito Joule para o aquecimento de determinados corpos de prova, que se resfriam por condução e convecção, de forma a simular o ciclo térmico em uma ZAC obtida por soldagem real. Tais simuladores comerciais estão disponíveis, mas a um custo muito alto. Assim, o desenvolvimento de um simulador físico de baixo custo é de grande importância. Em artigos anteriores, a proposição e construção deste simulador, que está baseado na modificação de um equipamento de soldagem a ponto por resistência, foram avaliadas como uso de corpos de prova cilíndricos de geometria fixa. Embora, a fonte consiga suprir a energia necessária para se atingir o ciclo térmico de aquecimento (alta temperatura e baixo tempo, não foi possível atingir um ciclo térmico de resfriamento próximo ao da realidade.

Todos os dados das simulações foram compilados na forma de uma modelo de regressão para se executar tal otimização da geometria. A partir desta metodologia foi possível construir diferentes diagramas CCT aplicados obtidos com os rápidos ciclos térmicos presentes na soldagem.

    1997-01-01

    The Space Station Furnace Facility (SSFF) is a facility located in the International Space Station United States Laboratory (ISS US Lab) for materials research in the microgravity environment. The SSFF will accommodate basic research, commercial applications, and studies of phenomena of metals and alloys, electronic and photonic materials, and glasses and ceramics. To support this broad base of research requirements, the SSFF will operate, regulate, and support a variety of Experiment Modules (EMs). To meet station requirements concerning the microgravity level needed for experiments, station is providing an active vibration isolation system, and SSFF provides the interface. SSFF physically consists of a Core Rack and two instrument racks (IRs) that occupy three adjacent ISS US Lab rack locations within the International Space Station (ISS). All SSFF racks are modified International Standard Payload Racks (ISPR). SSFF racks will have a 50% larger pass through area on the lower sides than ISPRs to accommodate the many rack to rack interconnections. The Instrument Racks are further modified with lowered floors and an additional removable panel (15" x 22") on top of the rack for access if needed. The Core Rack shall contain all centralized Core subsystems and ISS subsystem equipment. The two Instrument Racks shall contain the distributed Core subsystem equipment, ISS subsystem equipment, and the EMs. The Core System, which includes the Core Rack, the IR structures, and subsystem components located in the IRs serves as the central control and management for the IRs and the EMs. The Core System receives the resources provided by the International Space Station (ISS) and modifies, allocates, and distributes these resources to meet the operational requirements of the furnace. The Core System is able to support a total of four EMs and can control, support, and activate/deactivate the operations of two EMs, simultaneously. The IRs can be configured to house two small EMs or

    This document describes two models developed for the Laguna Verde Nuclear Power Station (LVNPP) using SCDAPSIM computer code. These models represent the LVNPP in normal operation with a nominal power of 1931 MWt and power uprate conditions of 2027 MWt. The steady states obtained by means of these models comply with the criteria established by the ANSI/ANS-3.5-1985 for nuclear power plant simulators. This criteria has been applied to the models of the LVNPP developed by CNSNS in want of some international accepted criteria for ''Best Estimation'' computer codes. These models will be the bases to carry out studies of validation of the own models as well as the analysis of diverse scenarios that evolve to a severe accident. (Author)

  1. Timber Mountain Precipitation Monitoring Station

    International Nuclear Information System (INIS)

    A precipitation monitoring station was placed on the west flank of Timber Mountain during the year 2010. It is located in an isolated highland area near the western border of the Nevada National Security Site (NNSS), south of Pahute Mesa. The cost of the equipment, permitting, and installation was provided by the Environmental Monitoring Systems Initiative (EMSI) project. Data collection, analysis, and maintenance of the station during fiscal year 2011 was funded by the U.S. Department of Energy, National Nuclear Security Administration, Nevada Site Office Environmental Restoration, Soils Activity. The station is located near the western headwaters of Forty Mile Wash on the Nevada Test and Training Range (NTTR). Overland flows from precipitation events that occur in the Timber Mountain high elevation area cross several of the contaminated Soils project CAU (Corrective Action Unit) sites located in the Forty Mile Wash watershed. Rain-on-snow events in the early winter and spring around Timber Mountain have contributed to several significant flow events in Forty Mile Wash. The data from the new precipitation gauge at Timber Mountain will provide important information for determining runoff response to precipitation events in this area of the NNSS. Timber Mountain is also a groundwater recharge area, and estimation of recharge from precipitation was important for the EMSI project in determining groundwater flowpaths and designing effective groundwater monitoring for Yucca Mountain. Recharge estimation additionally provides benefit to the Underground Test Area Sub-project analysis of groundwater flow direction and velocity from nuclear test areas on Pahute Mesa. Additionally, this site provides data that has been used during wild fire events and provided a singular monitoring location of the extreme precipitation events during December 2010 (see data section for more details).

    Staehle, R. L.

    1984-01-01

    This report presents an informal survey of experts in the field of spacecraft automation, with recommendations for which technologies should be given the greatest development attention for implementation on the initial 1990's NASA Space Station. The recommendations implemented an autonomy philosophy that was developed by the Concept Development Group's Autonomy Working Group during 1983. They were based on assessments of the technologies' likely maturity by 1987, and of their impact on recurring costs, non-recurring costs, and productivity. The three technology areas recommended for programmatic emphasis were: (1) artificial intelligence expert (knowledge based) systems and processors; (2) fault tolerant computing; and (3) high order (procedure oriented) computer languages. This report also describes other elements required for Station autonomy, including technologies for later implementation, system evolvability, and management attitudes and goals. The cost impact of various technologies is treated qualitatively, and some cases in which both the recurring and nonrecurring costs might be reduced while the crew productivity is increased, are also considered. Strong programmatic emphasis on life cycle cost and productivity is recommended.

  6. Insurance of nuclear power stations

    International Nuclear Information System (INIS)

    Electrical utility companies have invested large sums in the establishment of nuclear facilities. For this reason it is normal for these companies to attempt to protect their investments as much as possible. One of the methods of protection is recourse to insurance. For a variety of reasons traditional insurance markets are unable to function normally for a number of reasons including, the insufficient number of risks, an absence of meaningful accident statistics, the enormous sums involved and a lack of familiarity with nuclear risks on the part of insurers, resulting in a reluctance or even refusal to accept such risks. Insurers have, in response to requests for coverage from nuclear power station operators, established an alternative system of coverage - insurance through a system of insurance pools. Insurers in every country unite in a pool, providing a net capacity for every risk which is a capacity covered by their own funds, and consequently without reinsurance. All pools exchange capacity. The inconvenience of this system, for the operators in particular, is that it involves a monopolistic system in which there are consequently few possibilities for the negotiation of premiums and conditions of coverage. The system does not permit the establishment of reserves which could, over time, reduce the need for insurance on the part of nuclear power station operators. Thus the cost of nuclear insurance remains high. Alternatives to the poor system of insurance are explored in this article. (author)

  7. Waste management at power stations

    International Nuclear Information System (INIS)

    Like most other industrial processes, nuclear power stations produce waste in gaseous, liquid and solid forms. Gaseous and liquid wastes are routinely discharged from the stations after suitable treatment, the residual radioactivity being diluted and dispersed in the environment. The discharges are controlled and authorised under the Radioactive Substances Act and the environmental impact is minimal. In recent years low level wastes (LLW) have been sent to BNFL's disposal site at Drigg. Recent charges at Drigg have resulted in changed arrangements for the transport and disposal of low level wastes. This disposal route will be used until an alternative facility is brought into operation. Consideration is being given to volume reduction by supercompaction. Small amounts of intermediate level waste (ILW) such as spent ion exchange resins are now stored pending the availability of a disposal route. Such as a mobile waste treatment plant. In the case of Magnox debris a demonstration dissolution plant has been constructed at Dungeness and this will significantly reduce the volume of waste being stored whilst retaining the bulk of the activity on site for later treatment. At Trawsfynydd a few debris store will hold the fuel element debris in 500 litre drums. (author)

  8. Construction costs - nuclear power stations

    International Nuclear Information System (INIS)

    According to present development plans in the western industrial nations nuclear power will be able to cover 35 to 45% of power requirements in the mid 1980's. Although specific investment costs are higher for nuclear power plants than for other thermal power stations, nuclear plants are in a position today to generate power more economically than fossil fired plants into the upper part of the middle load sector. The relatively high proportion of fixed costs of the total power generation costs, and a still considerable potential to exploit the economy of scale, will contribute to minimize the inflationary burden on electric power generation. Nevertheless price development of nuclear power plants should be watched attentively, rapid price escalation for components, extremely long planning and construction times and exaggerated environmental protection requirements which serve no real purpose may reduce the economic benefit gained by nuclear energy. Electrical utilities will try to hold investment cost down by all means; for instance they will encourage standardization of nuclear power plants or order twin stations. For long term utilization of nuclear energy the development of high temperature reactors and fast breeders is a logical step forward. (author)

    The current phase of the Space Station Operating System study is based on the analysis, evaluation, and comparison of the operating systems implemented on the computer systems and workstations in the software development laboratory. Primary emphasis has been placed on the DEC MicroVMS operating system as implemented on the MicroVax II computer, with comparative analysis of the SUN UNIX system on the SUN 3/260 workstation computer, and to a limited extent, the IBM PC/AT microcomputer running PC-DOS. Some benchmark development and testing was also done for the Motorola MC68010 (VM03 system) before the system was taken from the laboratory. These systems were studied with the objective of determining their capability to support Space Station software development requirements, specifically for multi-tasking and real-time applications. The methodology utilized consisted of development, execution, and analysis of benchmark programs and test software, and the experimentation and analysis of specific features of the system or compilers in the study.

  10. Technology, safety and costs of decommissioning nuclear reactors at multiple-reactor stations

    International Nuclear Information System (INIS)

    Safety and cost information is developed for the conceptual decommissioning of large (1175-MWe) pressurized water reactors (PWR) and large (1155-MWe) boiling water reactors (BWR) at multiple-reactor stations. Three decommissioning alternatives are studied: DECON (immediate decontamination), SAFSTOR (safe storage followed by deferred decontamination), and ENTOMB (entombment). Safety and costs of decommissioning are estimated by determining the impact of probable features of multiple-reactor-station operation that are considered to be unavailable at a single-reactor station, and applying these estimated impacts to the decommissioning costs and radiation doses estimated in previous PWR and BWR decommissioning studies. The multiple-reactor-station features analyzed are: the use of interim onsite nuclear waste storage with later removal to an offsite waste disposal facility, the use of permanent onsite nuclear waste disposal, the dedication of the site to nuclear power generation, and the provision of centralized services

    2016-03-01

    Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

    The growth and the cracks propagation by fatigue are a typical degradation mechanism that is presented in the nuclear industry as in the conventional industry; the unstable propagation of a crack can cause the catastrophic failure of a metallic component even with high ductility; for this reason, activities of programmed maintenance have been established in the industry using inspection and visual techniques and/or ultrasound with an established periodicity allowing to follow up to these growths, controlling the undesirable effects; however, these activities increase the operation costs; and in the peculiar case of the nuclear industry, they increase the radiation exposure to the participant personnel. The use of mathematical processes that integrate concepts of uncertainty, material properties and the probability associated to the inspection results, has been constituted as a powerful tool of evaluation of the component reliability, reducing costs and exposure levels. In this work the evaluation of the failure probability by cracks growth preexisting by fatigue is presented, in pipes of a Reactor Core Isolation Cooling system (Rcic) in a nuclear power station. The software WinPRAISE 07 (Piping Reliability Analysis Including Seismic Events) was used supported in the probabilistic fracture mechanics principles. The obtained values of failure probability evidenced a good behavior of the analyzed pipes with a maximum order of 1.0 E-6, therefore is concluded that the performance of the lines of these pipes is reliable even extrapolating the calculations at 10, 20, 30 and 40 years of service.

    This document presents the analysis of the simulation of the loss of coolant accident at uprate power conditions, that is 2027 MWt (105% of the current rated power of 1931MWt). This power was reached allowing an increase in the turbine steam flow rate without changing the steam dome pressure value at its rated conditions (1020 psiaJ. There are also presented the results of the simulation of the main steam isolation va/ve transient at overpressure conditions 1065 psia and 1067 MWt), for Laguna Verde Nuclear Power Station. Both simulations were performed with the best estimate computer code TRA C BF1. The results obtained in the loss of coolant accident show that the emergency core coolant systems can recover the water level in the core before fuel temperature increases excessively, and that the peak pressure reached in the drywell is always below its design pressure. Therefore it is concluded that the integrity of the containment is not challenged during a loss of coolant accident at uprate power conditions.The analysis of the main steam isolation valve transients at overpressure conditions, and the analysis of the particular cases of the failure of one to six safety relief valves to open, show that the vessel peak pressures are below the design pressure and have no significant effect on vessel integrity.

    2016-07-01

    The Extreme Energy Event (EEE) experiment is devoted to the search of high energy cosmic rays through a network of telescopes installed in about 50 high schools distributed throughout the Italian territory. This project requires a peculiar data management infrastructure to collect data registered in stations very far from each other and to allow a coordinated analysis. Such an infrastructure is realized at INFN-CNAF, which operates a Cloud facility based on the OpenStack opensource Cloud framework and provides Infrastructure as a Service (IaaS) for its users. In 2014 EEE started to use it for collecting, monitoring and reconstructing the data acquired in all the EEE stations. For the synchronization between the stations and the INFN-CNAF infrastructure we used BitTorrent Sync, a free peer-to-peer software designed to optimize data syncronization between distributed nodes. All data folders are syncronized with the central repository in real time to allow an immediate reconstruction of the data and their publication in a monitoring webpage. We present the architecture and the functionalities of this data management system that provides a flexible environment for the specific needs of the EEE project.

    Hempsell, M.

    After the International Space Station is decommissioned in 2020 or soon after, Skylon will be an operating launch system and it is the obvious means to launch any successor in orbit infrastructure. The study looked at establishing 14 stations of 7 different types located from Low Earth Orbit to the Moon's surface with common elements all launched by Skylon. The key reason for the study was to validate Skylon could launch such an infrastructure, but the study's secondary objectives were to contribute to consideration of what should replace the ISS, and explore a ``multiple small station'' architecture. It was found that the total acquisition costs for LEO stations could be below 1 billion (2010) while for stations beyond LEO total acquisition costs were found to be between 3 and £5 billion. No technical constraints on the Skylon launch system were found that would prevent it launching all 14 stations in under 5 years.

    1987-01-01

    Expert systems and robotics technologies are to be significantly advanced during the Space Station program. Artificial intelligence systems (AI) on the Station will include 'scars', which will permit upgrading the AI capabilities as the Station evolves to autonomy. NASA-Ames is managing the development of the AI systems through a series of demonstrations, the first, controlling a single subsystem, to be performed in 1988. The capabilities being integrated into the first demonstration are described; however, machine learning and goal-driven natural language understanding will not reach a prototype stage until the mid-1990s. Steps which will be taken to endow the computer systems with the ability to move from heuristic reasoning to factual knowledge, i.e., learning from experience, are explored. It is noted that the development of Space Station expert systems depends on the development of experts in Station operations, which will not happen until the Station has been used extensively by crew members.

  2. Maintenance evaluation for space station liquid systems

    Flugel, Charles

    1987-01-01

    Many of the thermal and environmental control life support subsystems as well as other subsystems of the space station utilize various liquids and contain components which are either expendables or are life-limited in some way. Since the space station has a 20-year minimum orbital lifetime requirement, there will also be random failures occurring within the various liquid-containing subsystems. These factors as well as the planned space station build-up sequence require that maintenance concepts be developed prior to the design phase. This applies to the equipment which needs maintenance as well as the equipment which may be required at a maintenance work station within the space station. This paper presents several maintenance concepts for liquid-containing items and a flight experiment program which would allow for evaluation and improvement of these concepts so they can be incorporated in the space station designs at the outset of its design phase.

  3. Sustaining volcanism in Central Kamchatka

    Science.gov (United States)

    Nikulin, Alex

    Flux-induced melting in the mantle wedge acts as the driving mechanism of arc volcanism in subduction zone environments. The primary control on the geographical position of arc volcanic centers is the depth of the subducting plate beneath the overriding plate. Globally, the average depth to the subducting plate beneath volcanic arcs is estimated at ˜100km. Volcanoes of the Central Kamchatka Depression in Eastern Russia comprise the most active volcanic arc system in the world with the depth of the subducting Pacific plate beneath the arc estimated at 180-200km, greatly in excess of the global average. In my research I attempt to describe the special tectonic circumstances that explain the deviation of the subduction depth constraint on arc volcanism in Central Kamchatka. In my study I rely on geophysical and geochemical data and petrological modeling to propose a new geodynamic model to explain voluminous volcanic activity in Central Kamchatka. In the initial stage of the study I conducted a geophysical investigation using receiver function methodology to map and describe the contact of the subducting Juan de Fuca Plate in the well-instrumented Cascadia subduction zone. I calculated and compiled a database of receiver function profiles from stations along the extent of the Cascadia forearc and mapped a low velocity anisotropic zone proposed to be serpentinized material along the forearc axis. In the second stage of my study I applied a similar methodology to describe the sub-crustal structure of Central Kamchatka. Results of this effort suggested presence of a low-velocity zone in the upper mantle separate from the subducting Pacific plate. I proceeded to investigate the tectonic origin of this feature in the final stage of my dissertation work with the use of receiver function migration, geochemical analysis and petrological modeling. I was able to further constrain the position of the low velocity anomaly and derive geochemical and petrological evidence linking

    2016-01-01

    Upon commencement of my internship, I was in charge of maintaining the CoFR (Certificate of Flight Readiness) Tool. The tool acquires data from existing Excel workbooks on NASA's and Boeing's databases to create a new spreadsheet listing out all the potential safety concerns for upcoming flights and software transitions. Since the application was written in Visual Basic, I had to learn a new programming language and prepare to handle any malfunctions within the program. Shortly afterwards, I was given the assignment to automate the Station Program Note (SPN) Pull process. I developed an application, in Python, that generated a GUI (Graphical User Interface) that will be used by the International Space Station Safety & Mission Assurance team here at Johnson Space Center. The application will allow its users to download online files with the click of a button, import SPN's based on three different pulls, instantly manipulate and filter spreadsheets, and compare the three sources to determine which active SPN's (Station Program Notes) must be reviewed for any upcoming flights, missions, and/or software transitions. Initially, to perform the NASA SPN pull (one of three), I had created the program to allow the user to login to a secure webpage that stores data, input specific parameters, and retrieve the desired SPN's based on their inputs. However, to avoid any conflicts with sustainment, I altered it so that the user may login and download the NASA file independently. After the user has downloaded the file with the click of a button, I defined the program to check for any outdated or pre-existing files, for successful downloads, to acquire the spreadsheet, convert it from a text file to a comma separated file and finally into an Excel spreadsheet to be filtered and later scrutinized for specific SPN numbers. Once this file has been automatically manipulated to provide only the SPN numbers that are desired, they are stored in a global variable, shown on the GUI, and

    1987-01-01

    Perhaps the most critical structural system aboard the Space Station is the Solar Alpha Rotary Joint which helps align the power generation system with the sun. The joint must provide structural support and controlled rotation to the outboard transverse booms as well as power and data transfer across the joint. The Solar Alpha Rotary Joint is composed of two transition sections and an integral, large diameter bearing. Alpha joint bearing design presents a particularly interesting problem because of its large size and need for high reliability, stiffness, and on orbit maintability. The discrete roller bearing developed is a novel refinement to cam follower technology. It offers thermal compensation and ease of on-orbit maintenance that are not found in conventional rolling element bearings. How the bearing design evolved is summarized. Driving requirements are reviewed, alternative concepts assessed, and the selected design is described.

    This paper reports that, as an outgrowth of research into physical security systems, Sandia is investigating robotic technologies for improving physical security performance and flexibility. Robotic systems have the potential to allow more effective utilization of security personnel, especially in scenarios where they might be exposed to harm. They also can supplement fixed site installations where sensors have failed or where transient assets are present. The Remote Security Station (RSS) program for the defense Nuclear Agency is developing a proof-of-principle robotic system which will be used to evaluate the role, and associated cost, of robotic technologies in exterior physical security systems. The RSS consists of three primary elements: a fixed but quickly moveable tripod with intrusion detection sensors and assessment camera; a mobile robotic platform with a functionally identical security module; and a control console which allows an operator to perform security functions and teleoperate the mobile platform

    Radio station management has changed dramatically during the last few years. Operating in a stiff competition environment, radio stations need to focus on new business models, as they evolve from broadcasting to narrowcasting or nichecasting. Since a radio station operates simultaneously on two markets (the consumers and the advertisers) attention should be placed both on the radio production and the radio promotion, on-air as well as off-air.

Diante deste problema, analisou-se a possibilidade de introdução de um fator que medisse o índice de concordância dos provadores sobre determinado aspecto analisado. Para validação deste coeficiente, foi avaliada a concordância entre julgadores na análise sensorial para três diferentes amostras de suco de pinha (Annona squamosa L.: uma constituída apenas do suco de pinha sem leite e duas com diferentes concentrações pinha/leite. Utilizou-se a Análise de Componentes Principais (ACP e também a nova metodologia proposta pelos autores, com base na definição do desvio-padrão, aplicada às frequências absolutas das notas dos julgadores, para cada propriedade sensorial estudada. Com esta metodologia, definiu-se uma relação para o cálculo de uma medida de concordância entre os julgadores, denominada de coeficiente de concordância, a qual pode assumir valores de 0 a 100% e também permite comparações que não são possíveis, utilizando-se da ACP. Por fim, concluiu-se que tal metodologia é mais indicada que a ACP, na avaliação da concordância entre os julgadores na análise sensorial.The methods now used, for accomplishment of sensorial analysis, do not translate the results satisfactorily.

    2009-12-01

    Full Text Available A partir do início da década de 90, ocorreram diversas mudanças no ambiente institucional do cooperativismo brasileiro, em função dos problemas macroeconômicos que elevaram a alavancagem e a necessidade de as cooperativas obterem recursos financeiros junto a terceiros. Essa situação se intensificou nos últimos anos para manter a competitividade das organizações cooperativas no mercado. Em função da importância desse novo cenário, procurou-se estudar mecanismos de sinalização, com o objetivo de reduzir a assimetria de informações entre o mercado e os gestores das cooperativas. Assim, este trabalho desenvolve uma metodologia de rating para ser aplicada em cooperativas agropecuárias de forma a reduzir os problemas de seleção adversa e risco moral (moral hazard, que geram ineficiência no relacionamento entre essas organizações e o mercado financeiro; objetiva-se, também, averiguar a sua aplicabilidade, por meio de um estudo de caso. A partir dos resultados alcançados, é possível concluir que a metodologia é aplicável e que o sinalizador gerado, bem como as avaliações e os pesos, deveriam ser discutidos em comitês de rating, a exemplo do que é feito pelas agências especializadas. Como consideração final, é sugerida uma agenda de novas aplicações da metodologia para testá-la junto a outras organizações, de forma a consolidá-la como um sinalizador a ser usado pelo mercado e pelo sistema cooperativo.Owing to macroeconomic problems in Brazil in the late nineties, some modifications occurred in the agricultural cooperatives institutional environment that had influence on debt level and compromised the cooperative enterprises leverage on financial market resources.

  16. Themis - A solar power station

    Science.gov (United States)

    Hillairet, J.

    The organization, goals, equipment, costs, and performance of the French Themis (Thermo-helio-electric-MW) project are outlined. The program was begun for both the domestic energy market and for export. The installation comprises a molten eutectic salt loop which receives heat from radiators situated in a central tower. The salt transfers the heat to water for steam generation of electricity. A storage tank holds enough molten salt to supply one day's reserve of power, 40 MWh. A field of heliostats directs the suns rays for an estimated 2400 hr/yr onto the central receiver aperture, while 11 additional parabolic concentrators provide sufficient heat to keep the salt reservoir at temperatures exceeding 200 C. In a test run of several months during the spring of 1982 the heliostats directed the sun's rays with an average efficiency of 75 percent, yielding 2.3 MW of power at a system efficiency of 20.5 percent in completely automatic operation.

  17. Improving nuclear power station output

    International Nuclear Information System (INIS)

    The total annual output of Nuclear Electric's five advanced gas cooled reactor (AGR) stations has increased by more than 80% from 21.7 to 39.3 TW·h over the last four years since the company was formed. This has been achieved through increasing both the capability (maximum power output) and the availability of the reactors. The successive stages of technical modifications, testing and safety case preparation and approval by which the capability of each of the reactor units was raised, whilst ensuring safety, are detailed and the further stages that are planned for the future are outlined. The availability of the reactors has been increased by removing the constraints associated with refuelling operations, reducing statutory overhaul lengths and frequency, and reducing unplanned losses. In 1990, the fuel routes at four of the five stations operated too slowly to supply the fuel needed by the reactors and also required substantial periods of outage of the fuel route for modifications in order to consolidate their off-load refuelling safety cases. The programmes of work undertaken are outlined and the improved performance of the fuel route operations to match the increased output of reactor units is detailed. The future developments, particularly of on-load refuelling, are outlined. The lengths of statutory outages have been reduced by improved management and performance of plant operations and maintenance, and permission has also been received to extend the period between overhauls from 24 to 36 months. Unplanned losses have also been reduced. The improvements in output have not been achieved at the expense of safety nor by increasing the resources deployed. Indeed the reverse is true; key safety indicators show an improvement in both nuclear and industrial safety; and the manpower employed at the AGRs and the total annual expenditure in real terms have both decreased over the past four years.

    2011-12-01

    Full Text Available INTRODUÇÃO: A presença de hemácias dismórficas na urina é um forte indicativo da origem glomerular do sangramento, sendo uma ferramenta importante no diagnóstico de glomerulonefrites. Os cilindros hemáticos geralmente acompanham as hemácias dismórficas, sendo também fortes indicadores de hematúria glomerular, embora não sejam encontrados com frequência no exame parcial de urina. OBJETIVO: Comparar duas técnicas de concentração de amostras em uma série de exames de urina com hematúria dismórfica. MATERIAL E MÉTODOS: Foram selecionadas 249 amostras com hematúria dismórfica a partir de 4.277 amostras de urina de rotina. As amostras foram processadas utilizando-se duas técnicas: a convencional e a de concentração. O percentual de identificação dos cilindros hemáticos foi comparado de acordo com a metodologia utilizada. RESULTADOS: A presença de cilindros hemáticos pela técnica de concentração foi estatisticamente maior (52,6% em comparação com a positividade pela metodologia convencional (8,4% (p < 0,001. DISCUSSÃO E CONCLUSÃO: Sugere-se que a técnica convencional não concentrou suficientemente a amostra de urina e os cilindros hemáticos ficaram no sobrenadante, sendo descartados. A utilização da técnica de concentração aumentou a sensibilidade técnica para a pesquisa dos cilindros hemáticos. Portanto, a técnica de concentração, associada à presença de hemácias dismórficas, mostrou-se útil para aumentar a concordância dos dois parâmetros laboratoriais para a detecção da hematúria de origem glomerular como auxílio diagnóstico das glomerulopatias, importante causa de doença renal crônica.

O desenho e a construção dos mesocosmos são descritos em detalhes, como também a forma como foram inseridos lâminas para coleta e medida da comunidade perifítica e sedimento para avaliação da comunidade bentônica. O método utilizado foi o de fluxo contínuo, e vários parâmetros de qualidade de água foram medidos, além da determinação de resíduos na coluna d'água e no sedimento. A intenção de se utilizar um método de fluxo contínuo foi buscar uma situação mais próxima da realidade, a fim de que os resultados obtidos possam espelhar com maior exatidão os possíveis riscos provenientes do uso de substâncias químicas no controle das macrófitas. Alguns ajustes devem ser feitos nessa metodologia para melhor caracterização dos efluentes e calibração do sistema.This experiment aimed to analyze the methodology applied to evaluate the environmental impact caused by the use of herbicide to control macrophytes. The design and construction of the tanks are described in detail as well as the insertion of blades for periphyton and sediment sampling to evaluate the bentonic comunities. The flow-through method was used and several parameters of water quality were measured and residues detected in the water colunm and sediment. The flow-through methodology was chosen to create a situation closer to reality so that the results obtained could more precisely reflect the likely risks caused by chemical control of macrophytes. Some adjustments need to be made in this methodology for a better characterization of the effluents and calibration of the system.

  11. Microearthquakes at Valles Caldera, New Mexico: Improved Detection and Location with Two Additional Caldera Stations

    Science.gov (United States)

    Roberts, P. M.; House, L. S.; Ten Cate, J. A.

    2015-12-01

    The Los Alamos Seismic Network (LASN) has operated for 43 years, providing data to locate more than 2,500 earthquakes in north-central New Mexico. Roughly 1-2 earthquakes are detected and located per month within about 150 km of Los Alamos, a total of over 900 from 1973 to present. LASN's primary purpose is to monitor seismicity close to the Los Alamos National Laboratory (LANL) for seismic hazards; monitoring seismicity associated with the nearby Valles Caldera is secondary. Until 2010 the network was focused on monitoring seismic hazards and comprised only 7 stations, all near LANL or in the nearby Jemez Mountains. Just one station—PER, installed in 1998—was close enough to Valles Caldera to be able to detect microearthquakes located in or near the caldera. An initial study of the data from station PER between 1998 and 2002 identified and located 13 events with magnitudes less than 0.5 using the single-station hodogram technique. Those events were all located south of the caldera within a few kilometers of PER. Recently, two new digital broadband stations were installed inside the caldera, one on a northeastern ring-fracture dome, station CDAB, and the other on a northwestern dome, station SAMT. Also, station PER was upgraded with digital broadband instrumentation. Thus, LASN now can detect and record microearthquakes as small as magnitude -1.5 near the caldera, and they can be located using multiple arrival times. Several recent events located near station SAMT on the caldera's ring fracture are the first that have been seen in that area. Additional events were recorded (by all three stations) and located in the area south of the caldera where the earlier hodogram-only events were located. These new multi-station event recordings allow a more quantitative assessment of the uncertainties in the initial single-station hodogram locations. Each event is located using multiple arrival times as well as the hodogram method at as many as three stations. Thus

    Train stations play a vital role in the door to door travel experience of train passengers. From the passengers’ value of time perspective, the station is the weakest link in total time value of the journey. Within the station the transfer function – moving between the various transport modes and waiting at the next service - is the core function, because it connects all transport modes. Therefore, an optimal transfer process is a key requirement for a well performing station. The basic requi...

    Full Text Available There are many architectural design parameters for public transport stations which include urban and station level studies. Each station must be designed in accordance with the basic passenger requirements such as accessibility, safety, comfort, satisfaction and etc. Circulation spaces must be formed and sized to meet the minimum movement needs of passengers. For an underground station; main entrance region, position of gates, location and number of turnstiles, escalators, stairs, ramps, passageways, intermediate concourses and platforms must be arranged to minimize walking distances and to prevent congestion. In this study, circulation of passengers is simulated in a quantitatively verifiable manner, taking into account how individuals interact with each other and with the physical obstacles in their environment in a metro station. Virtual experiments are performed to see the continuity and density of pedestrian flow at different levels of Haram Area East Metro Station of the first metro line of Madinah Al-Munawwarah, Saudi Arabia. According to the predictions, more than 40.000 passengers are expected to use this station in one hour after a Friday prayer during Ramadan period in the year of 2040. That means a critically high travel demand and it is really significant to design the most convenient underground station for these passengers to fulfil the necessary requirements.

  5. Background noise spectra of global seismic stations

    Wada, M.M.; Claassen, J.P.

    1996-08-01

    Over an extended period of time station noise spectra were collected from various sources for use in estimating the detection and location performance of global networks of seismic stations. As the database of noise spectra enlarged and duplicate entries became available, an effort was mounted to more carefully select station noise spectra while discarding others. This report discusses the methodology and criteria by which the noise spectra were selected. It also identifies and illustrates the station noise spectra which survived the selection process and which currently contribute to the modeling efforts. The resulting catalog of noise statistics not only benefits those who model network performance but also those who wish to select stations on the basis of their noise level as may occur in designing networks or in selecting seismological data for analysis on the basis of station noise level. In view of the various ways by which station noise were estimated by the different contributors, it is advisable that future efforts which predict network performance have available station noise data and spectral estimation methods which are compatible with the statistics underlying seismic noise. This appropriately requires (1) averaging noise over seasonal and/or diurnal cycles, (2) averaging noise over time intervals comparable to those employed by actual detectors, and (3) using logarithmic measures of the noise.

    Popocatepetl, or Popo, the active volcano located about 70 km southeast of Mexico City, sends a plume south on January 23, 2001. The astronaut crew on the International Space Station Alpha observed and recorded this image as they orbited to the northeast of the volcano. Popo has been frequently active for six years. On this day, the eruption plume reportedly rose to more than 9 km above sea level [for reference, Popo's summit elevation is 5426 m (17,800 feet)]. Note the smaller ash plume below the main plume (arrow). The perspective from the ISS allowed the astronauts this unique 3 dimensional view. Popo is situated between two large population centers: Mexico City (more than 18 million people, and just off the image to the right) and Puebla (about 1.2 million people). The region's dense population provides the potential for extreme impacts from volcanic hazards. Recent eruptions have been frequent, and have resulted in evacuations around the mountain. The image ISS01-ESC-5316 is provided and archived by the Earth Sciences and Image Analysis Laboratory, Johnson Space Center.

  14. Kumatori deuteration station (KIDS) project

    International Nuclear Information System (INIS)

    It is quite well known that small-angle neutron scattering (SANS) is a powerful tool to study the quaternary structures of protein in solution state. One of the most fascinating characteristic features in SANS technique is its ability to discern hydrogen (H) from deuterium (D) due to the difference of scattering lengths. Taking advantage of intrinsic feature contrast variation SANS (CV-SANS), which modulates the both the contrasts of solvents and solutes make the detailed structural analyses on complex system possible. In addition deuteration labeling on protein samples offer little perturbation on their structure and functionality compared to other labeling method such as site-directed mutations. However the structural analyses on protein through SANS is quite limited compared to small-angle X-ray scattering (SAXS) despite of its unique property. It is considered that one of the obstacles for SANS study is the difficulty for the preparation of enough amounts of deutertaed proteins. In order to overcome such a situation we launched KumatorI Deuteration Station (KIDS) project, which dedicated to the preparation of deuterated (or controlled-deuterated) protein. At the poster session we would like to present our recent activity and fruitful results from KIDS project.

    The Central Himalayas comprise eight hill districts of the State of Uttar Pradesh, India. These mountains are the source of the Ganga and its main tributaries: the Yamuna, Ramganga and Sarda rivers. The identified hydro potential of the Ganga, Yamuna, Sarda and their tributaries in the Central Himalayas is about 30 000 MW, with an annual average energy potential of 100 TWh. The projects which have been completed so far have only developed 3.2 per cent of this potential. The projects which are now under construction will exploit another 10.4 per cent of the potential. Thus, the untapped potential is as much as 85 per cent of the total. The minor tributaries also offer vast potential for mini and micro hydroelectric stations. In most conservative estimates, this potential is about 2000 MW. (author).

The large number of fields and the small size of these conventional methods difficult dosimetry during treatment. The objective of this work was to develop a verification methodology in vivo dosimetry in stereotactic radiotherapy with the aid of the film radiochromic Linear Accelerator with multi leaf collimators Moduleaf. The technique uses film segments radiochromic Gafchromic EBT2, with dimensions of 1x1 cm{sup 2} in area outside the coupled micro-multileaf Moduleaf Siemens. These films were inserted in the region of the central axis of the beam. The films were irradiated and calibrated to obtain the factors that determine the size dependence of the dosimetric field. With these data, we designed a computer program which calculates the density of a film must acquire when subjected to an exposure in this setting. This study evaluated five non-coplanar plans, the first with 15 fields and the other with 25 fields. Before starting the procedure, the film segment is coupled to the device, and after the treatment, the relative density is evaluated and compared with the calculated. The average value of the verification at the time of radiation dosimetry compared with the calculated by the sheet was 1.5%. The data collected in this study showed a satisfactory agreement between measured and calculated by the program in the densitometer. Thus, a methodology was developed to verify in vivo dosimetry in radiotherapy and stereotactic linear accelerator collimators Moduleaf. (author)

    OBJECTIVE: The purpose of this study was to determine whether posters placed on the platforms of two train stations in Copenhagen, promoting use of the stairs, would encourage people to use the stairs rather than the adjacent escalator. An additional purpose was to see if the effect of the...... intervention was maintained for a week after the poster was removed. MEASUREMENTS: The number of people using stairs and escalators at Copenhagen Central Station and Østerport Train Station in Copenhagen was recorded before and during posters promoting stair use were placed on the platforms, and a week after...... the posters were removed. Two years after the posters were removed, data were collected for 1 week at Østerport Train Station (long-term post-intervention). RESULTS: At Copenhagen Central Station, the overall stair use increased from 12% before the intervention to 16% (P<0.0001) during the...
