    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. An analysis about the influence of the thermal storage on

    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.

    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.

    1980-01-01

    Federal market development strategies designed to accelerate the market penetration of central station applications of photovoltaic energy system are analyzed. Since no specific goals were set for the commercialization of central station applications, strategic principles are explored which, when coupled with specific objectives for central stations, can produce a market development implementation plan. The study includes (1) background information on the National Photovoltaic Program, photovoltaic technology, and central stations; (2) a brief market assessment; (3) a discussion of the viewpoints of the electric utility industry with respect to solar energy; (4) a discussion of commercialization issues; and (5) strategy principles. It is recommended that a set of specific goals and objectives be defined for the photovoltaic central station program, and that these goals and objectives evolve into an implementation plan that identifies the appropriate federal role.

    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)

    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.

  19. A super base station based centralized network architecture for 5G mobile communication systems

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available To meet the ever increasing mobile data traffic demand, the mobile operators are deploying a heterogeneous network with multiple access technologies and more and more base stations to increase the network coverage and capacity. However, the base stations are isolated from each other, so different types of radio resources and hardware resources cannot be shared and allocated within the overall network in a cooperative way. The mobile operators are thus facing increasing network operational expenses and a high system power consumption. In this paper, a centralized radio access network architecture, referred to as the super base station (super BS, is proposed, as a possible solution for an energy-efficient fifth-generation (5G mobile system. The super base station decouples the logical functions and physical entities of traditional base stations, so different types of system resources can be horizontally shared and statistically multiplexed among all the virtual base stations throughout the entire system. The system framework and main functionalities of the super BS are described. Some key technologies for system implementation, i.e., the resource pooling, real-time virtualization, adaptive hardware resource allocation are also highlighted.

  20. Crustal thickness in central Europe from single-station seismic noise autocorrelation analysis

    Science.gov (United States)

    Becker, Gesa; Knapmeyer-Endrun, Brigitte

    2016-04-01

    The InSight mission to Mars will place a single three-component seismometer on the planet's surface, requiring the application of single-station methods. In addition, seismicity on Mars is likely less abundant than on Earth, making it important to also use the available seismic noise. For these reasons different approaches of seismic noise autocorrelation have been tested with broadband three-component datasets from 12 stations across central Europe. These stations cover varying Moho depths of ca. 25-50 km depth. With the help of the autocorrelations, reflected body waves are extracted in order to estimate the crustal thickness at each station. This is of special relevance for Mars, where average crustal thickness is uncertain by a factor of two. The different approaches used are waterlevel normalized autocorrelation, with and without application of a short-term and long-term average filter to the spectrum of the data prior to autocorrelation, and phase autocorrelation. These approaches are compared and analyzed. Estimates for the Moho depths are made from the lag times of the reflected P-waves and compared to available Moho depth values at the stations. Due to the availability of three-component data these estimates can be cross-validated and in some cases not only P-wave reflections, but also possible S-wave and multiple reflections can be identified. The estimates compare well with the general trend of Moho depth expected for these stations. The consistency of results is further investigated by comparing different stations of the GERES array (aperture 2 km), which also allows to examine results for closely located broad-band and short-period stations side by side.

    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.

    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.

    About 68 million households in India rely on kerosene as a fuel for domestic lighting. Kerosene-based lighting devices, not only for poor quality of light, but also for the risks of indoor air pollution and fire hazards, etc. are not a desired option for domestic lighting purposes. Solar lantern is a better alternative in terms of its quality of illumination, durability and versatility of use. The dissemination model for solar lantern in India has so far been based on cash sales with or without the incentive of capital subsidy. This paper analyses several dissemination models including rental and fee-for-service based on centralized solar charging station concept for CFL- and LED-based designs of solar lanterns available in India. The basis of comparison is the acceptable daily costs or rental to the user as well as to the owner of the charging station. Further, the paper studies the impact of likely escalation in kerosene price on the acceptable daily rental and estimates the amount of subsidy required to make the charging station model viable for disseminating solar lanterns among rural households.

    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.

  12. Staff Draft Report. Comparative Cost of California Central Station Electricity Generation Technologies.

    2003-02-11

    This Energy Commission staff draft report presents preliminary levelized cost estimates for several generic central-station electricity generation technologies. California has traditionally adopted energy policies that balance the goals of supporting economic development, improving environmental quality and promoting resource diversity. In order to be effective, such policies must be based on comprehensive and timely gathering of information. With this goal in mind, the purpose of the report is to provide comparative levelized cost estimates for a set of renewable (e.g., solar) and nonrenewable (e.g., natural gas-fired) central-station electricity generation resources, based on each technology's operation and capital cost. Decision-makers and others can use this information to compare the generic cost to build specific technology. These costs are not site specific. If a developer builds a specific power plant at a specific location, the cost of siting that plant at that specific location must be considered. The Energy Commission staff also identifies the type of fuel used by each technology and a description of the manner in which the technology operates in the generation system. The target audiences of this report are both policy-makers and anyone wishing to understand some of the fundamental attributes that are generally considered when evaluating the cost of building and operating different electricity generation technology resources. These costs do not reflect the total cost to consumers of adding these technologies to a resources portfolio. These technology characterizations do not capture all of the system, environmental or other relevant attributes that would typically be needed by a portfolio manager to conduct a comprehensive ''comparative value analysis''. A portfolio analysis will vary depending on the particular criteria and measurement goals of each study. For example, some form of firm capacity is typically needed with wind

Falar de metodologia é falar de escolhas políticas e éticas que pautam qualquer pretensão investigativa, e não de discursos que priorizam um árido formalismo técnico. Dentro dessa ótica, pesquisar é, ao invés de procurar verdades absolutas, conectar-se com a dispersão dos acontecimentos em suas múltiplas direções, cartografando os movimentos que se afirmam em uma determinada realidade. É abrir-se para o inusitado, desviar-se, surpreender e desconhecer. Exemplificando essa forma de compreensão dá visibilidade a uma pesquisa realizada a partir desse eixo metodológico.

    1976-01-01

    A sequence of calibration signals composed of a station identification code, a transient from the release of the seismometer mass at rest from a known displacement from the equilibrium position, and a transient from a known step in voltage to the amplifier input are generated by the automatic daily calibration system (ADCS) now operational in the U.S. Geological Survey central California seismographic network. Documentation of a sequence of interactive programs to compute, from the calibration data, the complex transfer functions for the seismographic system (ground motion through digitizer) the electronics (amplifier through digitizer), and the seismometer alone are presented. The analysis utilizes the Fourier transform technique originally suggested by Espinosa et al (1962). Section I is a general description of seismographic calibration. Section II contrasts the 'Fourier transform' and the 'least-squares' techniques for analyzing transient calibration signals. Theoretical consideration for the Fourier transform technique used here are described in Section III. Section IV is a detailed description of the sequence of calibration signals generated by the ADCS. Section V is a brief 'cookbook description' of the calibration programs; Section VI contains a detailed sample program execution. Section VII suggests the uses of the resultant empirical transfer functions. Supplemental interactive programs by which smooth response functions, suitable for reducing seismic data to ground motion, are also documented in Section VII. Appendices A and B contain complete listings of the Fortran source Codes while Appendix C is an update containing preliminary results obtained from an analysis of some of the calibration signals from stations in the seismographic network near Oroville, California.

    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)

    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).

    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.

    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.

    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 (O{sub 3}), nitrogen dioxide (NO{sub 2}), sulfur dioxide (SO{sub 2}), and particulate matter (PM{sub 2.5}). 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 O{sub 3} and PM{sub 2.5}. However, SO{sub 2} and NO{sub 2} showed statistically significant decreasing trends. At the Carrot Creek Station, a pronounced decreasing trend in SO{sub 2} was observed, but there was no change in O{sub 3} and NO{sub 2}. The decreasing trends observed with SO{sub 2} 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.

    The Stockholm Central Railway Station in Sweden was investigated for public radiofrequency (RF) radiation exposure. The exposimeter EME Spy 200 was used to collect the RF exposure data across the railway station. The exposimeter covers 20 different radiofrequency bands from 88 to 5,850 MHz. In total 1,669 data points were recorded. The median value for total exposure was 921 μW/m2 (or 0.092 μW/cm2; 1 μW/m2=0.0001 μW/cm2) with some outliers over 95,544 μW/m2 (6 V/m, upper detection limit). The mean total RF radiation level varied between 2,817 to 4,891 μW/m2 for each walking round. High mean measurements were obtained for GSM + UMTS 900 downlink varying between 1,165 and 2,075 μW/m2. High levels were also obtained for UMTS 2100 downlink; 442 to 1,632 μW/m2. Also LTE 800 downlink, GSM 1800 downlink, and LTE 2600 downlink were in the higher range of measurements. Hot spots were identified, for example close to a wall mounted base station yielding over 95,544 μW/m2 and thus exceeding the exposimeter's detection limit. Almost all of the total measured levels were above the precautionary target level of 3–6 μW/m2 as proposed by the BioInitiative Working Group in 2012. That target level was one-tenth of the scientific benchmark providing a safety margin either for children, or chronic exposure conditions. We compare the levels of RF radiation exposures identified in the present study to published scientific results reporting adverse biological effects and health harm at levels equivalent to, or below those measured in this Stockholm Central Railway Station project. It should be noted that these RF radiation levels give transient exposure, since people are generally passing through the areas tested, except for subsets of people who are there for hours each day of work.

    A site-specific conceptual design and evaluation of a solar central receiver system integrated with an existing cogeneration facility are described. The system generates electricity and delivers a portion of that electricity and process steam to a natural gas processing plant. Early in the project, tradeoff studies were performed to establish key system characteristics. As a result of these studies the use of energy storage was eliminated, the size of the solar facility was established at 37.13 MW (sub t), and other site-specific features were selected. The conceptual design addressed critical components and system interfaces. The result is a hybrid solar/fossil central receiver facility which utilizes a collector system of Department of Energy second generation heliostats.

    Full Text Available The research station "Vaskiny Dachi" on the Yamal Peninsula was established in 1988. Activities aimed at monitoring of permafrost and related environmental features under a relatively low level of nature disturbances caused by gas field development. Cryogenic processes that may affect the environment and their structures have been of primary interest. Landslides are the most common cryogenic processes in Central Yamal in general and also in the proximity of the station. Field surveys of numerous landslides, analysis of their dependence on climatic parameters and their fluctuations resulted in novel classification of cryogenic landslides based on mechanisms of their development. Dating by radiocarbon and dendrochronology allows the separation of cycles of landslide activation. Cryogenic landslides control the development of other processes, such as thermal erosion, river channel erosion and thermokarst. It also affects topography, vegetation pattern, geochemistry of vegetation, ground water and soils. As a result, permafrost parameters, specifically active layer depth and ground temperature, moisture and ice content in the active layer, depend indirectly on landsliding. Monitoring within the framework of the main programs of the International Permafrost Association, such as Circumarctic Active Layer Monitoring (CALM, since 1993 and Thermal State of Permafrost (TSP, since 2011, play an important role among the research activities. From the collected data one can conclude that ground temperature increased on average by about 1 °C since the 1990s. At the same time, active layer fluctuations do not exactly follow the air temperature changes. Spatial changes in ground temperature are controlled by the redistribution of snow which is resulting from strong winds characteristic for tundra environments and the highly dissected relief of Central Yamal. Temporal variations rather depend on air temperature fluctuations but the rate differs in various

    The policy of the public utilities of the City of Geneva includes the promotion of renewable energy and the conservation of the environment. The erection of the most important hydroelectric power plant in the canton of Geneva at Verbois, on the Rhone River dates back to the years 1938 to 1944. Several retrofits have been made since then, the last dating from 1996 to 1998. In 2000, due to ecological considerations, a fish ladder was added, resulting in a loss of generated power equivalent to a water flow of 2 m{sup 3}/s at a height of 18.35 meters. In order to compensate for this energy loss, a micro hydropower station with a maximum output power of 316 kW was added. It is fitted with a Francis turbine with horizontal axis and fixed opening; the rotation speed is 605 rpm. A reduced power output could be traced back to the deposition of solids on the grids upstream of the water supply duct. The necessary modifications are discussed.

    A power station in central Slovakia emitted arsenic (As) in large quantities for over 30 years as a result of burning As-rich brown coal. Nowadays emissions of As are low. Over the lifetime of the plant's operation over 3000 tonne of As have been emitted into the environment. This paper aims to examine the concentrations of As in the soil around the power station, and also to investigate whether the coal burnt in the plant, and consequently the emissions from it, contained raised levels of six further heavy metals. Soil concentrations were compared to ground level air As concentrations predicted by an air dispersion model. Coal samples were taken from the power station and analysed to determine concentrations of As, Zn, Pb, Cu, Cr, Ni and Cd. Soil samples (n=113) were taken up to 12 km from the plant along a transect designed to follow the valley floor in which the power station is situated. Soil samples were analysed for concentrations of those elements for which coal was tested. Concentrations of As in coal were high (AM 518 {mu}g/g). Those of other heavy metals were, in general, low. Concentrations of soil As were substantially raised in the near vicinity of the plant but decreased within 5 km to concentrations similar to those in the rest of the district. Overall, levels within 10 km of the plant were slightly above those recommended for residential levels in the UK. Soil concentrations of other heavy metals were higher in the vicinity of the plant but none, overall was raised. Comparison of results from a previous air dispersion model of ground level air arsenic concentrations showed a moderate correlation (r=0.6) between modelled and measured values. Over its period of operation the power plant has contributed to raised levels of soil As in the local soils, though not substantially of other elements. Though now airborne As emissions are controlled, concern remains regarding soil arsenic concentrations and fugitive emissions from the plant that could be

    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)

    On March 2015, the Environmental Protection Agency of Tuscany Region (Central Italy) and the Laboratory of monitoring and environmental modelling published a Report on spatial representativeness of monitoring stations for Tuscan air quality, where they supported the decommissioning of modelling stations located in the Florentine Plain. The stations of Signa, Scandicci, and Firenze-Bassi, located in a further South area, were considered representative Believing that air quality of the Plain could be evaluated by these stations is a stretch. In this text the author show the inconsistency of the conclusion of the Report through correlation graphs comparing daily means of PM10 detected in the disposed stations and in the active ones, showing relevant differences between the reported values and the days when the limits are exceeded. The discrepancy is due to the fact that uncertainty of theoretical estimates is greater than the differences recorded by the stations considered as a reference and the areas they may represent. The area of the Plain has a population of 150,000 individuals and it is subject to a heavy environmental pression, which will change for the urban works planned for the coming years. The population's legitimate request for the analytical monitoring of air pollution could be met through the organization of participated monitoring based on the use of low-cost innovative tools.

    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. More data can be viewed at http://eol.jsc.nasa.gov/Videos/CrewEarthObservationsVideos/. US-Mexico border is obvious by the different

    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.

    The Gredos and Iruelas station (GIC3) is part of the ClimaDat IC3 network (http://climadat.es/). This station is located in the Gredos Natural Park at a latitude of 40.22° N and a longitude of -5.14° E in the Spanish central plateau. The ClimaDat network is made by 8 stations distributed around Spain and it has been developed with the aim of studying climatic processes and the responses of impacted systems, at different time and space scales. Since November 2012, measurements of CO2, CH4, and of the natural radioactive gas 222Rn are continuously performed at GIC3 station at 20 m agl and at 1100 m asl . Maximum,minimum and average values of meteorological parameters, such as ambient air humidity and temperature, wind speed and direction are also measured at GIC3 station. Particularly, the concentration series of 222Rn measured at GIC3 station are extremely useful to evaluate the exchange of this noble radioactive gas between the soil surface and the lower troposphere in this area, under different weather situations and environmental conditions. The Gredos Natural Park is located in a granitic basement and this type of soil presents a high porosity and permeability. Furthermore, granitic materials have high activity levels of 228U. These factors enable large amount of radon to escape from the deeper soil, giving radon flux values of 90-100 Bq m-2 h-1 . These radon flux values are much higher than the average radon flux over the Earth, which is about 50 Bq m-2 h-1 (Szegvary et al, 2009). On the other hand, this geographical area is frequently affected by snow and rain events which drastically reduce the local radon exhalation. It is also influenced by winds coming from the Atlantic Ocean, which are poor in radon and strong, causing an important mixing. In addition, the cold nights' stability leads to an observed nocturnal radon accumulation. All the aforementioned conditions influence atmospheric radon concentrations measured at the GIC3 station, enlarging the range

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

O presente trabalho tem como principal objetivo compreender dentre três práticas pedagógicas adotadas no Ensino de Astronomia, na terceira série do Ensino Médio, da Escola Estadual Colônia dos Pescadores, qual melhor cumpre o papel de formação e aprendizagem para vida. A pesquisa preliminar foi através de um questionário onde o intuito foi diagnosticar o conhecimento já existente acerca do tema em questão. O questionário é composto de vinte questões dissertativas e objetivas, onde os educandos das três turmas envolvidas o responderam. Este trabalho utiliza as seguintes metodologias: a tradicional, onde o professor é um repassador de informações, fazendo uso exclusivo de lousa e giz; a segunda também de forma tradicional, porém com auxílio de multimídia para desenvolvimento das aulas e aterceira sob forma de seminários, elaborados e apresentados pelos educandos, no qual o educador faz apenas as intervenções necessárias. Ao final do trabalho os alunos responderão novamente o questionário inicial para diagnosticar dentre as três metodologias utilizadas qual apresentou melhor resultado. Os resultados preliminares obtidos, já podem ser observados e, dos 119 alunos entrevistados, as respostas obtidas são as mais diversas e evidenciam que a grande maioria nunca teve em sua vida escolar o tema Astronomia. Ao serem questionados se já haviam estudado Astronomia as respostas foram: turma A: sim 43%; turma B: sim: 21%; turma C: sim: 24%. Porém quando questionados a respeito do significado de Astronomia observou-se que: turma A: 100% de acertos; turma B: 64% acertos; turma C: 84% de acertos, demonstrando claramente a aprendizagem em diferentes esferas, não dependendo unicamente da escola.

    Seismic hazard assessment and mitigation of catastrophes are primarily based on the identification and characterization of seismically active zones. These tasks still rely heavily on the existing knowledge of the seismic activity over the longest possible time period. The first seismic network in Equatorial Africa (IRSAC network) was operated from the Lwiro scientific base on the western shores of Lake Kivu between 1953 and 1963. Before this installation, the historical record of seismic activity in Central Africa is sparse. Even for the relatively short period concerned, spanning only 50-60 years, the historical record is far from being complete. A first attempt has been made by Herrinckx (1959) who compiled a list 960 felt seisms recorded at the meteorological stations between 1915 and 1954 in Congo, Rwanda and Burundi. They were used to draw a density map of felt seisms per square degree. We completed this data base by exploiting the meteorological archives and any available historical report to enlarge the database which now reaches 1513 entries between 1900 and 1959. These entries have been exanimate in order to identify possible historical seismic events. Those are defined by 3 or more quasi-simultaneous records observed over a relatively short distance (a few degrees of latitude/longitude) within a short time difference (few hours). A preliminary list of 115 possible historical seisms has been obtained, identified by 3 to 15 different stations. The proposed location is taken as the average latitude and longitude of the stations where the felt seisms were recorded. Some of the most important ones are associated to aftershocks that have been felt at some stations after the main shocks. The most recent felt seisms have been also recorded instrumentally, which helps to validate the procedure followed. The main difficulties are the magnitude estimation and the possible spatial incompleteness of the recording of felt seism evidence at the margin of the observation

    A seasonal field testing program was conducted during 1986 and 1987 to evaluate the effectiveness of behavioral barriers at Central Hudson Gas and Electric Corporations's Roseton Generating Station located in the euryhaline section of the Hudson River. This station was selected as representative of power plants with shoreline riverine/estuarine intake systems. Three commercially available devices (air bubble curtain, pneumatic gun, and underwater strobe light) were tested alone and in combination to determine their effectiveness in reducing impingement. The primary testing method incorporated three or four 6-h impingement collections during each test date, each consisting of two randomly assigned 3-h samples: one was an experimental test with a behavioral device in operation, the other a control test with no device operating. The effectiveness of the devices at excluding fish was determined by comparing impingement data from experimental and control periods. Results of the program do not establish that the deployment of underwater strobe lights, pneumatic guns, an air bubble curtain, or various combinations of the three devices will effectively lower fish impingement at power plants similar in design and location to the Roseton plant. Deterrent effectiveness was found to be species-specific and related to time of day. 51 refs., 67 figs., 72 tabs.

    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 $0.10 \\lambda^{-0.61}$.

    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.

    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.

    Volatile organic compounds (VOCs) from two sampling sites (HB and XB) in a power station centralized area, in Shuozhou city, China, were sampled by stainless steel canisters and measured by gas chromatography-mass selective detection/flame ionization detection (GC-MSD/FID) in the spring and autumn of 2014. The concentration of VOCs was higher in the autumn (HB, 96.87 μg/m(3); XB, 58.94 μg/m(3)) than in the spring (HB, 41.49 μg/m(3); XB, 43.46 μg/m(3)), as lower wind speed in the autumn could lead to pollutant accumulation, especially at HB, which is a new urban area surrounded by residential areas and a transportation hub. Alkanes were the dominant group at both HB and XB in both sampling periods, but the contribution of aromatic pollutants at HB in the autumn was much higher than that of the other alkanes (11.16-19.55%). Compared to other cities, BTEX pollution in Shuozhou was among the lowest levels in the world. Because of the high levels of aromatic pollutants, the ozone formation potential increased significantly at HB in the autumn. Using the ratio analyses to identify the age of the air masses and analyze the sources, the results showed that the atmospheric VOCs at XB were strongly influenced by the remote sources of coal combustion, while at HB in the spring and autumn were affected by the remote sources of coal combustion and local sources of vehicle emission, respectively. Source analysis conducted using the Positive Matrix Factorization (PMF) model at Shuozhou showed that coal combustion and vehicle emissions made the two largest contributions (29.98% and 21.25%, respectively) to atmospheric VOCs. With further economic restructuring, the influence of vehicle emissions on the air quality should become more significant, indicating that controlling vehicle emissions is key to reducing the air pollution.

    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.

Based on driving distance probability distribution of various electric vehicles obtained by statistical analysis, an uncertainty model of electric vehicle battery replacement demand is established. Considering the investment of centralized charging stations and lines, network loss and load shifting, a planning model for centralized charging stations is put forward. The hybrid intelligent optimization method, which combines the improved genetic algorithm with the self-adaptive particle swarm algorithm, is used to solve the above two layer programming models. The service area is divided by the weighted Voronoi diagram in order to balance the load rates of centralized charging stations. The simulation results show that the proposed model and method are effective and feasible for centralized charging station planning.

    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.

    In this sense, the station becomes the subject of a critical modification through an imaginary and physical excavation that reveals the immense, ‘total’ solidity of this archaeological find of our time. The project offers a new interpretation of correspondence between a plan and a construction system using a ‘principle of distancing’, a physical and temporal gap between the new parts and the ‘remains’. By reworking all the elements of the station – through a process of reassembling – the project witnesses to the tragedy of the Shoah, without any further comment. Through the critical interpretation of the document-monument, architecture reaffirms the ethical dimension of memory. Keywords: Memory, Narration, Archaeology, Distancing, Assemblage

    Aware of the increasing impact of human activities on the Earth system, Belgian Science Policy Office (Belspo) launched in 1997 a research programme in support of a sustainable development policy. This umbrella programme included the Belgian Scientific Programme on Antarctic Research. The International Polar Foundation, an organization led by the civil engineer and explorer Alain Hubert, was commissioned by the Belgian Federal government in 2004 to design, construct and operate a new Belgian Antarctic Research Station as an element under this umbrella programme. The station was to be designed as a central location for investigating the characteristic sequence of Antarctic geographical regions (polynia, coast, ice shelf, ice sheet, marginal mountain area and dry valleys, inland plateau) within a radius of 200 kilometers (approx.124 miles) of a selected site. The station was also to be designed as "state of the art" with respect to sustainable development, energy consumption, and waste disposal, with a minimum lifetime of 25 years. The goal of the project was to build a station and enable science. So first we needed some basic requirements, which I have listed here; plus we had to finance the station ourselves. Our most important requirement was that we decided to make it a zero emissions station. This was both a philosophical choice as we thought it more consistent with Antarctic Treaty obligations and it was also a logistical advantage. If you are using renewable energy sources, you do not have to bring in all the fuel.

    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.

    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.

Seguindo o ideal do cogito cartesiano de recobrimento do ser pelo saber, a ciência tem buscado tudo apreender em termos quantitativos, passível de mensuração.

    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.

    Discharges from pumping stations to rivers in dry weather have become an important issue which causes environmental complaints of residents and serious influence of water quality in central Shanghai. To guide the engineering and administrative measures used to reduce the volume of discharged water from pumping stations in dry weather as soon as possible,the subsidy policy needs to be implemented. The principles including water index evaluation,partial subsidies,and classified subsidies as well as encouraging and guiding to build the inspection and subsidy standards of discharges from pumping stations in dry weather were used in this paper. Tons of water to mix contact investigation and modification cost were about 1. 63 and 2. 67 yuan,respectively. The construction and modification cost of intercepting and draining water facilities were 108. 39 yuan/m3 . The combined sewer pumping station reduced the water level of pipeline operation to avoid fore-river discharges before rain weather and the cost of ton of water running increased 0. 091 5 yuan. The operation cost needed to reduce the water level of collecting basin to the lowest level in order to avoid maintenance discharges was 58. 5 yuan/104 m3 . Based on the reduction of subsidy standards of discharges from pumping stations in dry weather,it was expected to effectively reduce 19. 209 9 million volumes of discharged water in dry weather,which was 86. 58% of the total discharges amount. The basic subsidy of one-time engineering was 51. 201 2 million yuan. And the basic subsidy of annual operation cost was 0. 093 3 million yuan.%上海市中心城区泵站旱天放江已成为居民环保投诉、严重影响河道水质景观的主要问题,为引导削减泵站旱天放江量的工程性、管理性措施尽快实施,需实施资金补贴政策。该研究采用水量指标考核、分项补贴、分类补贴和鼓励引导原则,构建泵站旱天放江考核和补贴标准;估算确定吨水混接点

    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 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.

    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.

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.

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.

    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.

    Full Text Available Resumo: Recentemente, a tradição sociológica de Bourdieu tem despontado como uma tendência importante na pesquisa em educação em ciências. Neste artigo, apresentamos algumas das críticas de Bernard Lahire à abordagem de Bourdieu. O propósito central de nossa incursão pelas críticas de Lahire é introduzir e argumentar a metodologia dos retratos sociológicos como recurso importante para a pesquisa em educação científica. Após a descrição dessa metodologia, ela é exemplificada com um retrato sociológico aplicado ao estudo da evasão em um curso de licenciatura em química. O retrato de Diogo ilustra, no nível empírico, algumas propriedades básicas atribuídas às disposições individuais (variabilidade, gênese, transferibilidade, dicotomia e contextualidade. A partir desse retrato, ilustrou-se como a ressonância entre as disposições do aluno e da instituição de ensino permite explicar seu sentimento de adesão e pertencimento ao curso. Em seguida, são sublinhadas outras potencialidades dos retratos sociológicos para os propósitos da pesquisa em educação científica.

    Full Text Available Duas metodologias de expansão ao forno foram comparadas em 52 amostras de polvilho azedo de três Estados: Santa Catarina, Paraná e Minas Gerais. Os resultados obtidos permitiram visualizar uma proposta de classificação em nível nacional da expansão ao forno do polvilho azedo. No método instrumental foi usado o Farinógrafo Brabender para estabelecer uma massa de consistência padrão de 60UF e no método prático, a consistência semelhante da massa foi determinada de forma empírica. Com a metodologia instrumental obteve-se biscoitos com expansão superior à metodologia prática, mas maior coeficiente de variação, o que pode ser devido a maior sensibilidade do método. Ambas as metodologias poderão ter aplicação, dependendo da finalidade. A metodologia instrumental, pelo custo do equipamento, é mais adequada para laboratórios, desde que se utilize maior número de repetições, para reduzir o coeficiente de variação. Ambas as metodologias ensaiadas permitiram classificar as amostras com o mesmo perfil de desempenho. As amostras provenientes do Estado do Paraná apresentaram as maiores expansões ao forno quando comparados com os outros Estados. Pela metodologia prática a expansão média das amostras do Estado do Paraná foi de 14,1mL/g. As amostras do Estado de Minas Gerais apresentaram as menores expansões ao forno, em média de 13,3mL/g. Foi proposta neste artigo uma classificação para avaliar a qualidade do polvilho azedo, complementando a legislação brasileira que não estabelece este índice para o produto. Quanto à propriedade de expansão ao forno, as amostras avaliadas podem ser divididas em 3 tipos A, B e C. No tipo A (10% amostras de polvilhos azedo são classificadas como qualidade extra, no tipo B (80% os polvilhos são de média qualidade e o tipo C (10% de qualidade inferior. Os resultados obtidos pela metodologia prática permitiram estabelecer como tipo A o polvilho azedo que apresenta um índice de

    Full Text Available O presente artigo discute a existência de uma metodologia jurídica no Mercosul, um bloco econômico intergovernamental, tendo por base a elogiável experiência supranacional, desenvolvida na União Europeia. Explorado é o fato de acreditar-se ser adequado o Mercosul restringir-se, no presente momento e estágio da integração, ao seu modelo original. Para tanto, em um primeiro momento, observa-se qual é o direito que o Mercosul tem, depois, quais são as características do direito da União Europeia, bem como a existência de uma verdadeira metodologia jurídica europeia, tudo isso com o propósito de ser, ao seu final, proposta a construção de uma metodologia jurídica mercosulista. É necessário admitir que ainda muito dela não existe, mas isso não quer dizer que a europeia possa ou deva ser transferida para o Mercosul.

  5. Ecos popperianos na metodologia econômica de Elinor Ostrom

    Directory of Open Access Journals (Sweden)

    Sebastião Neto Ribeiro Guedes

    Full Text Available Resumo O artigo procura apresentar e analisar a discussão metodológica em economia empreendida por Elinor Ostrom, buscando identificar nela a influência da epistemologia popperiana. A ênfase voltou-se para os conceitos de Princípio da Racionalidade e de Análise Situacional, com os quais Popper contribuiu para a metodologia das Ciências Sociais. O artigo mostrou que esses conceitos encontraram equivalentes na análise da autora, e que Ostrom não apenas reconhece a importância da contribuição popperiana, mas dela faz o ponto de partida para sua proposta metodológica aplicada à governança de recursos comuns. O artigo refere-se, também, ao fato de que ao longo do tempo a metodologia dessa autora gradativamente abre a uma interlocução metodológica mais plural, conservando, no entanto, aspectos essenciais do projeto popperiano para a metodologia em Ciências Sociais, entre os quais a adesão ao individualismo metodológico.

    The lowest frequency band (70 - 450 MHz) of the Square Kilometre Array will consist of sparse aperture arrays grouped into geographically-localised patches, or stations. Signals from thousands of antennas in each station will be beamformed to produce station beams which form the inputs for the central correlator. Two-stage beamforming within stations can reduce SKA-low signal processing load and costs, but has not been previously explored for the irregular station layouts now favoured in radio astronomy arrays. This paper illustrates the effects of two-stage beamforming on sidelobes and effective area, for two representative station layouts (regular and irregular gridded tile on an irregular station). The performance is compared with a single-stage, irregular station. The inner sidelobe levels do not change significantly between layouts, but the more distant sidelobes are affected by the tile layouts; regular tile creates diffuse, but regular, grating lobes. With very sparse arrays, the station effective area...

    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.

    2002-01-01

    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.

    José Roberto Dourado Mafra

    2006-12-01

    Full Text Available Uma metodologia de Custeio para Ergonomia é apresentada neste artigo. Aqui o custeio é construído em paralelo ao processo da Análise de Ergonomia. Faz-se uma breve revisão da literatura. Essa metodologia de custeio abrange uma estimativa inicial de custos e a posterior aferição desses custos, decorrentes da ausência de Ergonomia no delineamento das situações em estudo; num outro momento, são feitos os cálculos dos custos das correções, ou investimentos necessários e a avaliação dos benefícios aportados pela nova concepção. A aplicação dessa metodologia é exemplificada em um estudo de caso de uma cozinha industrial, onde foi realizada uma Análise Ergonômica do Trabalho. No estudo de caso, a ausência de ergonomia é caracterizada por indicadores econômicos de efetividade na empresa. Conclui-se que essa metodologia de custeio mostra como problemas no desempenho impactam no negócio, economicamente, caracterizados em saúde, qualidade de vida e produtividade no trabalho. Nesse sentido, acredita-se ter contribuído com o estado da prática, contabilizando os custos e avaliando a viabilidade da solução.This paper discusses an ergonomics-based costing methodology, in which the costing process and the ergonomic work analysis are realized at the same time. A brief bibliographic review is presented. Two questions are pointed out regarding the economic evaluation of ergonomic interventions: one is the costing problem and the other evaluation itself. This costing methodology involves an initial costing estimate of the lack of ergonomics in the study case, followed by the checking of data validity; then, the costs of solutions are calculated and the benefits of the new conception are assessed. The methodology is applied to one example, i.e. a case study of an industrial kitchen, where an ergonomic work analysis was performed. In the studied case, the lack of ergonomics is characterized by economic indicators of company efficacy

    2012-06-01

    Full Text Available Este trabalho discute a problemática relacionada ao processo ensino/aprendizagem da disciplina de Química. Observamos que a metodologia utilizada pelo professor de Química do Ensino Médio está em desacordo com as novas tendências pedagógicas. Ainda se desenvolve uma metodologia de memorização e que, muito pouco, relaciona a Química com o cotidiano do aluno. O professor parece não saber estimular e incentivar o aluno a estudar Química, identificando e buscando informações relevantes para o seu aprendizado. Apesar desse ensino tradicional ainda perdurar, novas concepções metodológicas estão trazendo outros olhares sobre o ensino de Química. Isso fez nascer uma nova área de pesquisa: didática da química. Iniciativas até internacionais, como a celebração do Ano Internacional da Química, mostram que esta ciência é indispensável para a compreensão do universo. A partir dessa visão, as novas concepções metodológicas que surgem apontam para um ensino de Química que promete fornecer aos estudantes os mecanismos que lhes possibilite ter outra dimensão dessa ciência.

    Early space station designs are considered, taking into account Herman Oberth's first space station, the London Daily Mail Study, the first major space station design developed during the moon mission, and the Manned Orbiting Laboratory Program of DOD. Attention is given to Skylab, new space station studies, the Shuttle and Spacelab, communication satellites, solar power satellites, a 30 meter diameter radiometer for geological measurements and agricultural assessments, the mining of the moons, and questions of international cooperation. It is thought to be very probable that there will be very large space stations at some time in the future. However, for the more immediate future a step-by-step development that will start with Spacelab stations of 3-4 men is envisaged.

    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.

    O presente trabalho de intervenção foi realizado junto à Escola Estadual Colònia dos Pescadores na cidade de Caraguatatuba, com très turmas do terceiro ano do Ensino Médio, envolvendo 119 alunos com idades entre 16 e 19 anos. A fase inicial foi composta de um questionário de vinte questíes dissertativas e objetivas, aplicado pelo professor titular da sala, que era o mesmo nas très turmas, para diagnosticar nos educandos os conceitos prévios sobre Astronomia e, partindo destes realizar um trabalho de intervenção nas classes envolvidas utilizando, em cada uma, metodologias diferentes: (A) sob forma de seminários, elaborados e apresentados pelos educandos, no qual o educador faz apenas as intervençíes necessárias; (B) de forma tradicional, com auxílio de multimídias para desenvolvimento das aulas e a terceira (C) tradicional, fazendo uso exclusivo de lousa e giz. Ao final do trabalho os alunos responderam novamente o questionário inicial para diagnosticar dentre as très metodologias utilizadas qual apresentou melhores aplicaçíes, os resultados iniciais foram comparados com os finais. Quando questionados a respeito do significado de Astronomia observou-se inicialmente que os acertos na turma A foram de 100%, turma B: 64%, turma C: 84%, após a intervenção os acertos foram: 100%, 97% e 85% respectivamente, demonstrando que houve um avanço significativo na turma B, a turma A manteve seu índice e a turma C evoluiu, porém não tanto quanto a B. Quando interrogados sobre quantos planetas vocè acha que existem em nosso Sistema Solar? os acertos foram: turma A: 39%, turma B: 48% e turma C: 46%, após o desenvolvimento do trabalho os acertos foram 94%, 97% e 90% respectivamente. Dentro das respostas obtidas observa-se que a metodologia tradicional com o auxílio de multimeios, aplicada na turma B, demonstrou melhores resultados, sendo a mais significativa. Outra conclusão muito importante é que apesar de o tema Astronomia ser amplamente

    special focus when conducting UIC 406 capacity analyses.This paper describes how the UIC 406 capacity method can be expounded for stations. Commonly for the analyses of the stations it is recommended to include the entire station including the switch zone(s) and all station tracks. By including the switch...... zone(s) the possible conflicts with other trains (also in the opposite direction) are taken into account leading to more trustworthy results. Although the UIC 406 methodology proposes that the railway network should be divided into line sections when trains turn around and when the train order...... is changed, this paper recommends that the railway lines are not always be divided. In case trains turn around on open (single track) line, the capacity consumption may be too low if a railway line is divided.

    Space Station Freedom operations management concepts must be responsive to the unique challenges presented by the permanently manned international laboratory. Space Station Freedom will be assembled over a three year period where the operational environment will change as significant capability plateaus are reached. First Element Launch, Man-Tended Capability, and Permanent Manned Capability, represent milestones in operational capability that is increasing toward mature operations capability. Operations management concepts are being developed to accomodate the varying operational capabilities during assembly, as well as the mature operational environment. This paper describes operations management concepts designed to accomodate the uniqueness of Space Station Freedoom, utilizing tools and processes that seek to control operations costs.

    The Programa de Ahorro de Energia para el Sector Electrico (PAESE) (Program for Energy Conservation for the Electric Sector) in collaboration with the Instituto de Investigaciones Electricas (IIE), decided to evaluate technically and economically the possibilities of operating the Comision Federal de Electricidad`s Thermoelectric Power Stations (TPS), eventually to be retired as cogeneration units in supplying thermal energy to industry. The study was focussed to the Monterrey and San Jeronimo Power Stations, determining in a first stage, the optimum radius for handling and transporting steam and/or hot water and so to define the industries that potentially could obtain heat energy from the TPS, in this stage the thermal needs of the evaluated industries were determined (pressure, temperature and flow). In a second stage, the different arrangements to be made to operate the selected TPS, so as to be in position of satisfying such thermal energy demands were evaluated. This paper presents the results of this study.

    In 1988, the city of Montreal took possession of the Centre de Tri et d`Elimination des Dechets (CTED) which since 1968 has received about 30 million tonnes of waste, making it Canada`s largest, and North America`s third largest, sanitary waste disposal site. The management of this site presented an enormous challenge to the city because of its location near the centre of the city, the concern about the environmental impacts and the quality of life for residents in the area. It was noted that the uncontrolled release of methane from the sanitary landfill site could potentially pose serious environmental threats to the area. To address this problem the Gazmont generating station was developed to capture and utilize the biogas to generate electricity. Several studies, including an evaluation of the amount of biogas available for exploitation, were conducted before the project was inaugurated in the fall of 1996. Subsequently, a contract was negotiated with Hydro-Quebec to harness the electricity generated in the process to its distribution system. The project generates enough electricity to provide electricity for the needs of 8,200 homes in the area. A description of the process involved in generating electricity from biogas was provided.

    2010-09-01

    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

    The configuration of the Space Station under design studies by NASA is limited only by the capabilities of the Shuttle and the purposes to which it is applied. Once the standard interlocks, launch vibration modes, and pallet designs are fixed, all other assembly of modular components, testing, and trim will be performed in space. The Station will serve for long-term experiments, as a base for planetary missions asembly, launch, and retrieval, and for loading and launching multiple satellites on an orbital transfer vehicle. Materials processing research will be carried out in the Station, as will various scientific and commercial remote sensing activities. The first operational version (1990) will require four Shuttle launches to reach an assembled mass of 70,000 kg drawing 30 kWe from solar panels and housing a crew of five. By the year 2000 the station will support 10-12 crew members in five habitat modules, will be 31 m long, will have cost $18-20 billion, and will be returning $2 billion per year. The station will be periodically reboosted to higher orbits that decay suficiently for orbiter rendezvous for supplies and assignments.

    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.

    tion and transport is usually the most costly part of any waste management system; and when waste is transported over a considerable distance or for a long time, transferring the waste from the collection vehicles to more efficient transportation may be economically beneficial. This involves...... a transfer station where the transfer takes place. These stations may also be accessible by private people, offering flexibility to the waste system, including facilities for bulky waste, household hazardous waste and recyclables. Waste transfer may also take place on the collection route from small...... satellite collection vehicles to large compacting vehicles that cannot effectively travel small streets and alleys within the inner city or in residential communities with narrow roads. However, mobile transfer is not dealt with in this chapter, which focuses on stationary transfer stations. This chapter...

  19. Hydrogen vehicle fueling station

    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.

    1990-03-01

    The Western Area Power Administration (Western) proposes to construct, operate, and maintain a new Kiowa Creek Switching Station near Orchard in Morgan County, Colorado. Kiowa Creek Switching Station would consist of a fenced area of approximately 300 by 300 feet and contain various electrical equipment typical for a switching station. As part of this new construction, approximately one mile of an existing 115-kilovolt (kV) transmission line will be removed and replaced with a double circuit overhead line. The project will also include a short (one-third mile) realignment of an existing line to permit connection with the new switching station. In accordance with the Council on Environmental Quality (CEQ) regulations for implementing the procedural provisions of the National Environmental Policy Act of 1969 (NEPA), 40 CFR Parts 1500--1508, the Department of Energy (DOE) has determined that an environmental impact statement (EIS) is not required for the proposed project. This determination is based on the information contained in this environmental assessment (EA) prepared by Western. The EA identifies and evaluates the environmental and socioeconomic effects of the proposed action, and concludes that the advance impacts on the human environment resulting from the proposed project would not be significant. 8 refs., 3 figs., 1 tab.

  9. 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.

    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. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created.

    Full Text Available O objetivo deste trabalho foi desenvolver e validar uma metodologia de análise da adaptabilidade e da estabilidade fenotípica baseada em regressão quantílica (RQ. 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".

    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.

    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.

    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.

    Full Text Available 10.12957/cadest.2013.15770A metodologia usada atualmente na Embrapa para avaliar os impactos sociais e ambientais das tecnologias geradas pelos seus centros de pesquisa é composta por indicadores ponderados que são dependentes de critérios subjetivos, não permitindo avaliar a influência de cada indicador sobre os demais e nem sobre os índices finais gerados. Desse modo, a proposta deste artigo é definir novos pesos na construção desses índices. O diferencial da metodologia proposta é o uso de métodos estatísticos de análise multivariada na construção dos pesos, oferecendo uma alternativa ao método usado atualmente pelos seus centros de pesquisa. A abordagem metodológica aqui utilizada padroniza todas as variáveis, com o intuito de eliminar a influência de localização e escala. Todas as análises são feitas após o ranqueamento das variáveis, gerando grandezas adimensionais e robustas nas componentes dos índices de impactos social e ambiental. Nota-se que esses índices são analisados separadamente. Ao final da análise conclui-se que a metodologia proposta diminui o grau de subjetividade na escolha dos pesos dos indicadores e ajuda a identificar com mais clareza qual deles exerce maior influência nos índices de impactos das tecnologias analisadas

    In Italy in 1967, geothermal electric power production was 2.66% of the national energy production. The implementation of traditional and nuclear power plants is described. The trend in conventional thermoelectric power plants is characterized by ever-increasing block capacities (100-160 MW at present), they are expected to increase to 600 MW in Europe and to 1200 MW in the USA 10 years from now. Nuclear power plants with pressurized-water reactors, boiling-water reactors, and graphite-gas reactors have been built recently in Italy. Studies are being conducted in the area of high-speed reactors and breeder reactors. A description is presented of a power station using geothermal energy. At the end of 1967, geothermal power plants with an electrical capacity of 340 MW were in operation. Generally, U.S. thermoelectrical engine blocks with high productivity were used. The thermodynamic characteristics of these blocks are described in detail. The most powerful engine in the field in Italy- a turbocompressore Franco Tosi- was constructed in the ENEL central Castlenuovo Val Cecina in the Larderello region. The compressor is fed by a combined flow of steam, CO/sub 2/ and H/sub 2/S. It is characterized by a load of 22 t/h and an input pressure of 0.0905 atm at the outlet. The absorbed power is 2.28 MW at a velocity of 50 rotations/sec. Thirty figures are presented.

    Taiwan has more than 300 Global Positioning System (GPS) tracking stations maintained by the Ministry of the Interior (MOI), Academia Sinica, the Central Weather Bureau and the Central Geological Survey. In the future, GPS tracking stations may replace the GPS control points after being given a legal status. Hence, the data quality of the tracking stations is an increasingly significant factor. This study considers the feasibility of establishing a system for monitoring GPS receivers. This investigation employs many data-quality indices and examines the relationship of these indices and the positioning precision. The frequency stability of the GPS receiver is the most important index; the cycle slip is the second index and the multipath is the third index. An auto-analytical system for analysing GPS data quality and monitoring the MOI's tracking stations can quickly find and resolve problems, or changes in station environment, to maintain high data quality for the tracking stations.

    2010-04-01

    Full Text Available Tem-se por objetivo discutir a abordagem dos riscos ocupacionais segundo dois enfoques: o tributário às metodologias tradicionais em segurança do trabalho, cujo enfoque de análise é o das normatizações determinadas por técnicos especializados na área e, outro, que propõe a participação dos trabalhadores. Como abordagem participativa, a referência é a Psicodinâmica do Trabalho e a Ergonomia. A revisão da literatura indica que, embora haja esforço em implantar políticas públicas e de gestão, via participação mais efetiva dos trabalhadores, observa-se, ainda, uma supremacia de metodologias tradicionais na análise dos riscos ocupacionais. Analisam-se suas causas reafirmando a necessidade de novos enquadres teórico-metodológicos.

    Kurz, Rainer; Ohanian, Sebouh; Lubomirsky, Matt [Solar Turbines Incorporated, San Diego, CA (United States)

    2003-07-01

    This paper discusses issues that influence the decision on the arrangement of compressors and the type of equipment in gas pipeline compressor stations. Different concepts such as multiple small units versus single large units are considered, both regarding their impact on the individual station and the overall pipeline. The necessity of standby units is discussed. Various concepts for drivers (gas turbine, gas motor and electric motor) and compressors (centrifugal and reciprocating) are analyzed. The importance of considering all possible operating conditions is stressed. With the wide range of possible operating conditions for the pipeline in mind, the discussion is brought into the general context of operational flexibility, availability, reliability, installation issues, remote control, and operability of gas turbine driven centrifugal compressors compared to other solutions such as electric motor driven compressors or gas engine driven reciprocating compressors. The impact of different concepts on emissions and fuel cost is discussed. Among the assumptions in this paper are the performance characteristics of the compressor. This paper outlines how these performance characteristics influence the conclusions. (author)

Solahart International, Solsearch Pty. Ltd. And the universities of Sidney and New South Wales are cooperating in the project, and this first plant being partly funded by the Australian Greenhouse Office. The solar plant will be attached to a 1440 MW(e) coal fired plant. The 17000 m{sup 2} array will be the largest array in Australia, producing a peak of 13 MW of thermal energy which will offset the use of coal in the generation of electricity. It will use direct steam generation and will feed either steam or hot water at 265 Celsius degrees directly into the power station preheating cycle. The CLFR system, first developed by the University of Sidney and Solsearch Pty. Ltd., is simple and offers small reflector size, low structural cost, fixed receiver geometry. Initial installed plant costs are approximately US$1000 per kWe, but this includes the effect of high up-front design costs and the cost should drop substantially in the second and subsequent plants.

    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.

  3. Southeast regional experiment station. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1994-08-05

    This is the final report of the Southeast Regional Experiment Station project. The Florida Solar Energy Center (FSEC), a research institute of the University of Central Florida (UCF), has operated the Southeast Regional Experiment Station (SE RES) for the US Department of Energy (DOE) since September 1982. Sandia National Laboratories, Albuquerque (SNLA) provides technical program direction for both the SE RES and the Southwest Regional Experiment Station (SW RES) located at the Southwest Technology Development Institute at Las Cruces, New Mexico. This cooperative effort serves a critical role in the national photovoltaic program by conducting system evaluations, design assistance and technology transfer to enhance the cost-effective utilization and development of photovoltaic technology. Initially, the research focus of the SE RES program centered on utility-connected PV systems and associated issues. In 1987, the SE RES began evaluating amorphous silicon (a-Si) thin-film PV modules for application in utility-interactive systems. Stand-alone PV systems began receiving increased emphasis at the SE RES in 1986. Research projects were initiated that involved evaluation of vaccine refrigeration, water pumping and other stand-alone power systems. The results of this work have led to design optimization techniques and procedures for the sizing and modeling of PV water pumping systems. Later recent research at the SE RES included test and evaluation of batteries and charge controllers for stand-alone PV system applications. The SE RES project provided the foundation on which FSEC achieved national recognition for its expertise in PV systems research and related technology transfer programs. These synergistic products of the SE RES illustrate the high visibility and contributions the FSEC PV program offers to the DOE.

    Full Text Available As cascas do caule de Simarouba amara Aubl., Simaroubaceae, são amplamente utilizadas pela medicina popular brasileira e de vários países das Américas Central e do Sul para o tratamento de malária, parasitas intestinais, diarreia, anemia e febre. Apesar de os quassinoides serem considerados os marcadores quimiotaxonômicos da espécie, a indisponibilidade de padrões para comercialização tem sido um dos grandes obstáculos à realização de seu controle de qualidade. Diante disso, o propósito deste estudo foi o desenvolvimento e validação de metodologia analítica por espectrofotometria para a quantificação do teor de taninos totais das cascas do caule de S. amara, visto que esta classe de metabólitos é uma das mais abundantes e representativas já descritas para a espécie. O método proposto baseou-se na quantificação a 760 nm, após a adição do reagente Folin-Ciocalteu, e sua validação incluiu todos os parâmetros preconizados pela RE 899. Os resultados indicaram que o método proposto foi adequadamente desenvolvido e validado, constituindo ferramenta analítica útil para o controle de qualidade de S. amara.

    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

    Kohrs, Richard

    NASA field centers and contractors are organized to develop 'work packages' for Space Station Freedom. Marshall Space Flight Center and Boeing are building the U.S. laboratory and habitation modules, nodes, and environmental control and life support system; Johnson Space Center and McDonnell Douglas are responsible for truss structure, data management, propulsion systems, thermal control, and communications and guidance; Lewis Research Center and Rocketdyne are developing the power system. The Canadian Space Agency (CSA) is contributing a Mobile Servicing Center, Special Dextrous Manipulator, and Mobile Servicing Center Maintenance Depot. The National Space Development Agency of Japan (NASDA) is contributing a Japanese Experiment Module (JEM), which includes a pressurized module, logistics module, and exposed experiment facility. The European Space Agency (ESA) is contributing the Columbus laboratory module. NASA ground facilities, now in various stages of development to support Space Station Freedom, include: Marshall Space Flight Center's Payload Operations Integration Center and Payload Training Complex (Alabama), Johnson Space Center's Space Station Control Center and Space Station Training Facility (Texas), Lewis Research Center's Power System Facility (Ohio), and Kennedy Space Center's Space Station Processing Facility (Florida). Budget appropriations impact the development of the Space Station. In Fiscal Year 1988, Congress appropriated only half of the funds that NASA requested for the space station program ($393 million vs. $767 million). In FY 89, NASA sought $967 million for the program, and Congress appropriated $900 million. NASA's FY 90 request was $2.05 billion compared to an appropriation of $1.75 billion; the FY 91 request was $2.45 billion, and the appropriation was $1.9 billion. After NASA restructured the Space Station Freedom program in response to directions from Congress, the agency's full budget request of $2.029 billion for Space Station

    Full Text Available Resumo Atualmente, com o avanço da tecnologia de corte e solda, perfis de aço com aberturas sequenciais na forma circular, denominados perfis celulares, vêm sendo bastante utilizadas como vigas de edificações. A ABNT NBR 8800:2008 e as normas estrangeiras não abordam vigas de aço e vigas mistas de aço e concreto com perfil celular, o que contribui para que o seu uso seja limitado. Foi desenvolvido e aferido um programa computacional para o dimensionamento de vigas mistas de aço e concreto com perfil celular biapoiadas de acordo com duas metodologias distintas da literatura. Um estudo paramétrico abordando vigas mistas com perfis celulares obtidos de dois perfis I de aço laminados comerciais foi realizado. Nesse estudo, a influência dos parâmetros geométricos do perfil celular e do comprimento do vão da viga na resistência e na forma de colapso foi analisada. Foi possível concluir que em muitas situações o uso de vigas mistas com perfil celular é vantajoso em relação às vigas mistas de alma cheia.

    Full Text Available Considerando a existência de assimetria de informação entre gestores e investidores, Myers (1984 afirma que a formação da estrutura de capital por parte das empresas está baseada em uma hierarquia de captação conhecida como Pecking Order Theory (POT, favorecendo seqüencialmente a utilização de recursos internos, emissão de dívida e, por último, emissão de ações. A verificação empírica esbarra em questões metodológicas, sendo a POT por vezes confirmada e outras negada. Neste artigo, propõe-se uma metodologia diferente, reconhecendo as características das empresas como tamanho, lucratividade e crescimento, para explicar o financiamento do déficit, utilizando um modelo de dados em painel. Analisou-se uma amostra de 313 empresas listadas na Bovespa de 2000 a 2005. Os resultados indicam que unicamente as empresas de menor tamanho na amostra, de lucratividade negativa e baixo crescimento, apresentam aderência (fraca às previsões da POT. Assim, essa teoria não pode ser considerada uma teoria geral para explicar a estrutura de capital das empresas.

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.

    Full Text Available A separação entre consciência e realidade ocorrida a partir de Descarte com o racionalismo e suas conseqüências, atinge todas as ciências. A realidade passa a ser representação. O mundo se torna virtualidade. A educação sofre influência do objetivismo e, a pedagogia, como ciência da educação, é reduzida à metodologia. A pedagogia, em certo sentido, fragmentou-se. Sua preocupação não mais se volta para o ideal do dever-ser que é colocado pela educação, mas passa a se preocupar com formas, técnicas e metodologias. A preocupação da pedagogia com o conhecimento passa a não ser mais de meio, mas de finalidade. A fenomenologia surge também com a preocupação de superar a antinomia entre sujeito e objeto decorrente do idealismo e do racionalismo. O objetivo desse texto é mostrar a partir do texto de Edmund Husserl, a Crise da Humanidade Européia, que o objetivismo incrustado nas ciências humanas atingiu a educação e, conseqüentemente, a pedagogia como ciência desta reduzindo a pedagogia à metodologia, bem como à biopsicopedagogização da mesma.

    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.

    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

    An autonomous, low-power atmospheric lidar instrument is being developed at NASA Goddard Space Flight Center. This compact, portable lidar will operate continuously in a temperature controlled enclosure, charge its own batteries through a combination of a small rugged wind generator and solar panels, and transmit its data from remote locations to ground stations via satellite. A network of these instruments will be established by co-locating them at remote Automatic Weather Station (AWS) sites in Antarctica under the auspices of the National Science Foundation (NSF). The NSF Office of Polar Programs provides support to place the weather stations in remote areas of Antarctica in support of meteorological research and operations. The AWS meteorological data will directly benefit the analysis of the lidar data while a network of ground based atmospheric lidar will provide knowledge regarding the temporal evolution and spatial extent of Type la polar stratospheric clouds (PSC). These clouds play a crucial role in the annual austral springtime destruction of stratospheric ozone over Antarctica, i.e. the ozone hole. In addition, the lidar will monitor and record the general atmospheric conditions (transmission and backscatter) of the overlying atmosphere which will benefit the Geoscience Laser Altimeter System (GLAS). Prototype lidar instruments have been deployed to the Amundsen-Scott South Pole Station (1995-96, 2000) and to an Automated Geophysical Observatory site (AGO 1) in January 1999. We report on data acquired with these instruments, instrument performance, and anticipated performance of the AWS Lidar.

    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

    Full Text Available Electric vehicle as the main development direction of the future automotive industry, has gained attention worldwide. The rationality of the planning and construction of the power station, as the foundation of energy supply, is an important premise for the development of electric vehicles. In full consideration of the electric demand and electricity consumption, this paper proposes a new construction mode in which charging station and centralized charging station are appropriately combined and presents a location optimization model. Not only can this model be applied to determine the appropriate location for the power station, but it can use the queuing theory to determine the optimal number of power equipment, with which we can achieve the minimum costs. Finally, taking a certain city as an example, the optimum plan for power station is calculated by using this model, which provides an important reference for the study of electric vehicle infrastructure planning.

    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.

    The Long Wavelength Array (LWA) will be a new multi-purpose radio telescope operating in the frequency range 10-88 MHz. Upon completion, LWA will consist of 53 phased array "stations" distributed over a region about 400 km in diameter in the state of New Mexico. Each station will consist of 256 pairs of dipole-type antennas whose signals are formed into beams, with outputs transported to a central location for high-resolution aperture synthesis imaging. The resulting image sensitivity is estimated to be a few mJy (5 sigma, 8 MHz, 2 polarizations, 1 hr, zenith) in 20-80 MHz; with resolution and field of view of (8", 8 deg) and (2",2 deg) at 20 MHz and 80 MHz, respectively. All 256 dipole antennas are in place for the first station of the LWA (called LWA-1), and commissioning activities are well underway. The station is located near the core of the EVLA, and is expected to be fully operational in early 2011.

    1985-01-01

    The cheap and efficient generation of power is an essential requirement for the success and prosperity of any community and is especially important to third world countries. It is therefore logical that the more technologically advanced nations should seek to produce power stations for the developing countries. Power plant can now be designed into a packaged form that may be readily exported and commissioned. This valuable and interesting collection of papers were originally presented at a seminar organised by the Power Industries Division of the Institution of Mechanical Engineers. Topics considered include the developing world market for packaged power stations using indigenous fuels; multi-fuel systems for power generation; packaging, modularisation, and containerisation of equipment for power boilers for export; compact coal-fired industrial plant; rural woodburning power stations; biomass gasification based power generation technology and potential; gas fed reciprocating engine development; packaged heavy duty gas turbines for power generation; and criteria for assessing the appropriateness of package power technologies in developing countries.

    2014-12-01

    Full Text Available Trata-se de reflexão acerca dos encontros e desencontros entre as metodologias pedagógicas ativas e a educação popular, no contexto da formação dos profissionais de saúde. Parte-se de uma reflexão acerca das bases epistemológicas da educação popular e das principais metodologias ativas, consideradas no contexto de sua utilização na formação dos profissionais de saúde. A educação popular propõe uma fusão radical entre os meios e fins pedagógicos, já que a conscientização é ao mesmo tempo metodologia e objetivo formativo. As metodologias ativas podem ser métodos identificados com um processo pedagógico centrado no aluno e produtor de autonomia, desde que não sejam utilizadas como métodos isolados, dentro de uma lógica utilitária característica da educação bancária. Neste sentido, conclui-se que a educação popular pode ser um importante analisador das metodologias ativas, ajudando a consolidar sua utilização em processos formativos libertadores, no contexto dos cursos de saúde.

    The fabrication of the modules for the ITER Central Solenoid (CS) has started in a dedicated production facility located in Poway, California, USA. The necessary tools have been designed, built, installed, and tested in the facility to enable the start of production. The current schedule has first module fabrication completed in 2017, followed by testing and subsequent shipment to ITER. The Central Solenoid is a key component of the ITER tokamak providing the inductive voltage to initiate and sustain the plasma current and to position and shape the plasma. The design of the CS has been a collaborative effort between the US ITER Project Office (US ITER), the international ITER Organization (IO) and General Atomics (GA). GA’s responsibility includes: completing the fabrication design, developing and qualifying the fabrication processes and tools, and then completing the fabrication of the seven 110 tonne CS modules. The modules will be shipped separately to the ITER site, and then stacked and aligned in the Assembly Hall prior to insertion in the core of the ITER tokamak. A dedicated facility in Poway, California, USA has been established by GA to complete the fabrication of the seven modules. Infrastructure improvements included thick reinforced concrete floors, a diesel generator for backup power, along with, cranes for moving the tooling within the facility. The fabrication process for a single module requires approximately 22 months followed by five months of testing, which includes preliminary electrical testing followed by high current (48.5 kA) tests at 4.7K. The production of the seven modules is completed in a parallel fashion through ten process stations. The process stations have been designed and built with most stations having completed testing and qualification for carrying out the required fabrication processes. The final qualification step for each process station is achieved by the successful production of a prototype coil. Fabrication of the first

In cellular networks, the location of mobile stations can be estimated roughly by proximity sensing methods and methods based on an evaluation of the characteristics of base stations (fingerprinting. Basic characteristics of the UMTS standard The radio network controller (RNC has three different roles and is therefore known as: Controlling RNC (CRNC, Serving RNC (SRNC and Drifting RNC (DRNC. The Local Measurement Unit (LMU performs radio measurements (measuring the delay of signals from base stations to the LMU and forwards the data to the CRNC. The main location functions are performed within the Serving RNC which can operate in two modes: RNC central and central SAS (Standalone SMLC. The RNC in the RNC central mode controls the flow of requirements for the localization, chooses the method of localization, provides information as necessary and, finally, estimates the location of the user. The SAS mode performs the procedures based on the requirements of the service radio network controller (SRNC. The SAS executes the global location (Global Navigation Satellite System and location on the uplink, based on measuring the time difference U-TDoA (Uplink - Time Difference of Arrival. Methods of locating the MS in a UMTS network In the UMTS network, depending on the used network infrastructure,  both the station and network-based method can be used, i.e. determining the MS location can be performed on the MS or on the network side.

    André Luiz Olivier da Silva

    2015-05-01

    Full Text Available O presente trabalho aborda o processo de conhecimento da natureza humana, mais especificamente o processo mental de associação de ideias, tendo como referência a metodologia empirista proposta por David Hume. Com base nessa metodologia, indaga-se como a investigação filosófico-científica pode explicar a origem das ideias e o seu processo associativo: como, afinal, a mente humana processa suas ideias? Para responder a indagação, pretende-se analisar a abordagem descritiva do empirismo proposto por Hume, com o objetivo de auferir as percepções da natureza humana a partir da distinção entre impressões e ideias. As impressões sensíveis desempenham um importante papel na formação das ideias, pois são percepções mais vinculadas a elementos empíricos e, em razão disso, mais fortes, vívidas e intensas, ao ponto de impulsionar o processo associativo de ideias na natureza humana. Toda ideia deriva sempre de uma impressão – eis o célebre princípio do empirismo que ainda hoje continua a servir de base para as ciências empíricas.

    Science.gov (United States)

    Garrett, Henry B.; Gabriel, Stephen B.; Murphy, Gerald B.

    1990-01-01

    This paper describes the key environment/system interactions associated with the Space Station and its companion polar platform and defines the range of test environments that will need to be simulated. These environments include the neutral atmosphere, the ionospheric plasma, natural and man-made particulates, the ambient magnetic field, the South Atlantic Anomaly, and the ram/wake environment. The system/environment interactions include glow, oxygen erosion, drag, radiation effects, induced electric fields, high-voltage solar-array effects, and EMC/EMI associated with plasma/neutral gas operations. The Space Station and its associated systems pose unique demands on the ability to simulate these effects; synergistic effects require multiple environments to be simulated simultaneously, and the long life requirements require proper scaling of the exposure time. The analysis of specific effects and the calibration or improvement of ground test techniques will likely require in situ evaluation. Qualification and acceptance testing, because of cost and the impractically of extensive on-orbit analysis/modification, will likely remain ground test objectives except in very rare cases.

    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.

    A polarographic method is described for the iodine species determination, iodide and iodate in water solutions. the iodate can be determined by differential pulse polarography. Calibration curves and the detection and determination limits have been obtained. Iodides is oxidized to iodate with sodium hypochlorite and the excess of oxidizing agent is destroyed with sodium sulphide. The concentration of iodide is calculated as the difference between the concentration of iodate in the sample before and after the oxidation. As an application, species of iodine in samples coming from the experimental plants GIRS (Gaseous Iodine Removal by Sprays) of Nuclear Fission Department of the CIEMAT, dedicated to fission products containment studies in nuclear power station, were determined.

    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)

    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.

    The Struve Geodetic Arc was developed in Years 1816 to 1855, 200 years ago. Historic information on the points of the Struve Geodetic Arc are included in the UNESCO World Heritage list in 2005. Nevertheless, the sites of many points are still not identified nor included in the data bases nowadays. Originally STRUVE arc consisted of 258 main triangles with 265 triangulation points. Currently 34 of the original station points are identified and included in the in the UNESCO World Heritage list. identified original measurement points of the Meridian Arc are located in Sweden (7 points), Norway (15), Finland (83), Russia (1), Estonia (22), Latvia (16), Lithuania (18), Belorussia (28), Ukraine (59) and Moldova (27). In Year 2002 was initiated another large coverage project - European Position Determination System "EUPOS®". Currently there are about 400 continuously operating GNSS (Global Navigation Satellite Systems) stations covering EU countries Estonia, Latvia, Lithuania, Poland, Czech Republic, Slovakia, Hungary, Bulgaria, Romania and East European countries Ukraine and Moldavia. EUPOS® network is a ground based GNSS augmentation system widely used for geodesy, land surveying, geophysics and navigation. It gives the opportunity for fast and accurate position determination never available before. It is an honorable task to use the EUPOS® system for research of the Struve triangulation former sites. Projects with Struve arc can popularize geodesy, geo-information and its meaning in nowadays GIS and GNSS systems. Struve Arc and its points is unique cooperation cross-border object which deserve special attention because of their natural beauty and historical value for mankind. GNSS in geodesy discovers a powerful tool for the verification and validation of the height values of geodetic leveling benchmarks established historically almost 200 years ago.

    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.

    This paper describes the performance of the land mobile earth station using the Amplitude Companded Single Sideband (ACSSB) modulation technique developed for mobile satellite communications and results of the field experiments which were conducted in rural, suburban, and urban areas. This ACSSB system uses a 3-kHz pilot tone, and the voice frequency band is from 300 to 2500 Hz. The experiments show that the required C/N0 for voice communications is 40 dBHz and the required C/N0 for pilot signal tracking is 34 dBHz. Voice quality in rural and suburban areas was degraded slightly. In urban areas shadowings due to the presence of large buildings and trees caused signal losses. A comparison of the ACSSB system with the conventional narrow-band frequency-modulation system indicates that the ACSSB system can transmit voice signals more efficiently.

    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

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

    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

    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.

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. Assim, para suprir tal limitação, simulações foram executadas em elementos para determinar a geometria ótima em função do tempo de resfriamento (ciclo térmico desejado. 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. Tais diagramas são apresentados e comparados com os poucos encontrados na literatura, com boa concordância.The joining of metals is often associated to

  18. Uma metodologia baseada no modelo SCOR® e em inferência fuzzy para apoiar a avaliação de desempenho de fornecedores

    Directory of Open Access Journals (Sweden)

    Francisco Rodrigues Lima Junior

    Full Text Available Resumo Na literatura acadêmica, tanto a seleção quanto a avaliação para o desenvolvimento de fornecedores vêm sendo abordadas como um problema de tomada de decisão no qual um conjunto de fornecedores é avaliado com base em múltiplos critérios de desempenho. Embora já existam centenas de metodologias quantitativas voltadas para o apoio à etapa de seleção de fornecedores, a avaliação de desempenho objetivando o desenvolvimento de fornecedores ainda é pouco explorada na literatura. Além disso, a maioria das abordagens existentes apresentam algumas limitações devido ao uso de técnicas inadequadas. Diante disso, este estudo propõe uma nova metodologia de apoio à avaliação de desempenho de fornecedores, desenvolvida a partir da combinação de sistemas de inferência fuzzy com alguns indicadores de desempenho do modelo SCOR® (Supply Chain Operations Reference. A abordagem proposta permite avaliar aspectos relacionados ao desempenho das operações e aos custos do fornecedor. Os resultados dessa avaliação são usados para categorizar os fornecedores com desempenho similar e indicar diretrizes adequadas para o gerenciamento de cada grupo de fornecedores. Visando demonstrar o processo de modelagem e uso, bem como avaliar a adequabilidade da proposta, foi realizada uma aplicação piloto que envolveu a avaliação de 10 fornecedores de uma empresa do setor automotivo. Quatro sistemas de inferência fuzzy foram implementados usando MATLAB® e parametrizados de acordo com os julgamentos de dois funcionários da empresa. Também foi realizada uma análise de sensibilidade para verificar a consistência dos resultados fornecidos por esses sistemas. Os resultados obtidos reforçam a adequação da metodologia proposta e das parametrizações realizadas durante a implementação. Quando comparada com as metodologias de avaliação de fornecedores encontradas na literatura, esta abordagem apresenta vantagens como o apontamento de

    tareas mas afectada por esta situacion es la operacion de los sistemas electricos frente a la presencia de fallas, donde la primera labor a realizar por parte del personal de operacion de la red es la pronta ubicacion del lugar de falla dentro del sistema. 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.

  10. Modeling passenger flows in public transport stations

    Directory of Open Access Journals (Sweden)

    Cem Kırlangıçoğlu

    2015-06-01

    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.

  13. Background noise spectra of global seismic stations

    Energy Technology Data Exchange (ETDEWEB)

    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.

    Full Text Available Nos últimos anos as metodologias feministas têm influenciado fortemente a psicologia e as ciências sociais em geral, trazendo para o domínio da investigação novas possibilidades de pesquisa e de entendimento das dinâmicas sociais. A denominada crise positivista, muito marcada pelas críticas feministas à objectividade e neutralidade da ciência, legitimou a emergência de portentosas ferramentas analíticas, entre as quais a reflexividade. Este artigo explora a importância da adopção da reflexividade no processo de investigação e a sua influência na construção de uma ciência mais responsável. São discutidos os pontos de convergência entre a reflexividade e os pressupostos que presidem à utilização das metodologias feministas na psicologia.In recent years feminist methodologies has greatly influenced psychology and social sciences in general, bringing up to the research field new possibilities of analysis and knowledge about social dynamics. The positivist crisis, affected in a large extent by feminist critics related with objectivity and neutrality of science, legitimated the emergence of potent analytic tools, among them reflexivity. This paper explores the importance of adopting reflexivity in the research process and its influence in the construction of a more responsible science. Convergent topics between reflexivity and the principles that underlie feminist methodologies in psychology are discussed.

    Full Text Available O artigo apresenta os fundamentos da metodologia de construção do Índice de Percepções Organizacionais (IPO. Este instrumento permite aos gestores apreender as percepções e satisfação dos funcionários acerca da organização, e orientar mudanças sobre os problemas identificados. Considera-se que as percepções são sempre um resultado, a um determinado momento do tempo, de um "encontro" entre uma subjetividade individual e outra coletiva, esta última referindo-se à dimensão das representações socialmente construídas. O IPO expressa as percepções positivas e/ou negativas dos membros da organização e incorpora dados de pesquisa referentes a quatro dimensões organizacionais: infra-estrutura; gestão; clima e cultura. A metodologia reúne em um só instrumento dados de pesquisa e instrumento de avaliação, visando a orientar intervenções e acompanhar mudanças ao longo do tempo.This article presents the methodological basis for elaborating an Organizational Perceptions Index. The tool allows one to grasp the perceptions of organization members and solve some problems identified in the process. It is assumed that perceptions are the result of individual and collective subjectivities, the latter referring to culturally-bounded, socially-constructed representations. The Organizational Perceptions Index expresses the positive or negative perceptions of organization members and integrates data related to four organizational dimensions: infra-structure, management, environment, and culture. The methodology integrates research data in an evaluation tool, with the aim of orienting interventions and monitoring changes over time.

  10. Space Station thermal storage/refrigeration system research and development

    Science.gov (United States)

    Dean, W. G.; Karu, Z. S.

    1993-02-01

    Space Station thermal loading conditions represent an order of magnitude increase over current and previous spacecraft such as Skylab, Apollo, Pegasus III, Lunar Rover Vehicle, and Lockheed TRIDENT missiles. Thermal storage units (TSU's) were successfully used on these as well as many applications for ground based solar energy storage applications. It is desirable to store thermal energy during peak loading conditions as an alternative to providing increased radiator surface area which adds to the weight of the system. Basically, TSU's store heat by melting a phase change material (PCM) such as a paraffin. The physical property data for the PCM's used in the design of these TSU's is well defined in the literature. Design techniques are generally well established for the TSU's. However, the Space Station provides a new challenge in the application of these data and techniques because of three factors: the large size of the TSU required, the integration of the TSU for the Space Station thermal management concept with its diverse opportunities for storage application, and the TSU's interface with a two-phase (liquid/vapor) thermal bus/central heat rejection system. The objective in the thermal storage research and development task was to design, fabricate, and test a demonstration unit. One test article was to be a passive thermal storage unit capable of storing frozen food at -20 F for a minimum of 90 days. A second unit was to be capable of storing frozen biological samples at -94 F, again for a minimum of 90 days. The articles developed were compatible with shuttle mission conditions, including safety and handling by astronauts. Further, storage rack concepts were presented so that these units can be integrated into Space Station logistics module storage racks. The extreme sensitivity of spacecraft radiator systems design-to-heat rejection temperature requirements is well known. A large radiator area penalty is incurred if low temperatures are accommodated via a

    Through the 2009 American Recovery and Reinvestment Act (ARRA), the USGS allocated funding to help support research capabilities, as well as improve and upgrade facilities in the bureau. As part of this effort, the USGS contracted a consortium consisting of principals from academia and commerce to perform geotechnical site characterization at 189 seismographic station sites—185 in California and four in the central U.S. In this pilot project of the Advanced National Seismic System (ANSS), site characterizations will be conducted at: 130 Southern California Seismographic Network (SCSN), 25 California Geological Survey (CGS), 30 Northern California Seismographic Network (NCSN), and four Central U.S. (CEUS) sites. Each site investigation, involving passive and active surface-wave techniques, includes one or more of established approaches such as the horizontal-to-vertical spectral ratio (HVSR), 2-D array microtremor, 1-D refraction microtremor (ReMi), spectral analysis of surface wave (SASW), and multi-channel analysis of surface wave (MASW) methods. From this multi-method approach, we determine Vs (shear-wave velocity) profiles and the calculated Vs30 (the average shear-wave velocity in the upper 30 meters depth) for each site. In general, preliminary results based on field reports indicate observed records match expected values for surficial geologic conditions. Unexpected results are typically attributable to inaccurate or coarse map information and alternative explanations are verified through interpretations of local geologic structure observed during field investigations. For example, we find map-based geology to be consistent with observed records at the SCSN station CI.PLS, but not the case for CI.CWC, where inaccurate map information are at odds with our recorded velocities. At station CI.TIN (near edge of basalt outcrop) and NCSN station NC.MMLB (on rhyolite outcrop), the records observed in the shallow surface do not match expected rock values. Our pilot

  12. Modelling of Train Noise in Underground Stations

    Science.gov (United States)

    Kang, J.

    1996-08-01

    TNS, a computer model for predicting the temporal and spatial distribution of train noise in underground stations, is developed. The train is regarded as a series of sections, and the train noise distribution in a station is calculated by inputting the sound attenuation from a train section source in the underground system (i.e., the station and tunnel). This input can be obtained by physical scale modelling. The prediction by TNS in an underground station in London shows good agreement with site measurements. A series of computations in the station demonstrates that: (1) the overall level of the train noise in the area near the end walls is slightly less than the other areas; (2) some conventional architectural acoustic treatments in the station are effective when a train is still in the tunnel but not as helpful when the train is already in the station; and (3) train noise has a significant effect on the speech intelligibility of public address systems as measured by the Speech Transmission Index (STI).

  14. Is Central Asia really exsiccating?

    Science.gov (United States)

    Aizen, V. B.; Aizen, E. M.; Surazakov, A. B.

    2008-12-01

    At the end of 20th and the beginning of 21st century central Asia oases suffered from serious drought caused lack of water for agriculture, economy growth and population increase. However, people of this region always experienced lack of water for irrigation and fought a war over the rights to control river streams. The drying up of central Asian rivers is not a new phenomenon according to the ancient manuscripts. Thus, lets see about what has happened with the past century climate and water resources of central Asia using the long-term observational data. We analyzed data from more than 200 meteorological stations and stream gauges over the central Asia in elevation range from 25 m. b.s.l. to 4,000 m. a.s.l. to understand the last 100 years variability in climate and water resources, examining changes in the extreme and mean monthly air temperatures, precipitation and river runoff. The evaluation of seasonal snow and glacier's covered areas between 1970th and 2007th in central Asia derived from AVHRR, MODIS, Hexagon KH-9, Landsat ETM and ASTER data exhibit 15% reduction of the seasonal snow covered area and 10.1% of the glacier area. It has been found that during last twenty years the duration of snowmelt, from the date of maximum snow cover to date of its disappearance, reduced by 30 days and in 2007 was equal to 138 days in the central Asian mountains. The decrease of seasonal snow cover is not a linear process. The further decrease may be accelerated due to increase of rainfall instead of snowfall in early spring months at high elevations, and consequently a lesser heat expenditure for the snowmelt. The growth in summer air temperatures, especially observable since the 1970th, accompanied by increase of evapotranspiration and precipitation, notably in summer and autumn, and at high elevations over 3,000 m, and at the western peripheral mountain ridges. Average difference in the means of annual air temperatures for the two thirty-year periods before and after

    The minimum Space Station Freedom accommodations required for initial assembly, repair, and refurbishment of the Lunar aerobrake were investigated. Baseline Space Station Freedom support services were assumed, as well as reasonable earth-to-orbit possibilities. A set of three aerobrake configurations representative of the major themes in aerobraking were developed. Structural assembly concepts, along with on-orbit assembly and refurbishment scenarios were created. The scenarios were exercised to identify required Space Station Freedom accommodations. Finally, important areas for follow-on study were also identified.

    Watson, James C; Sandroni, Paola

    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.

    In the last two decades Resistive Plate Chambers were employed in the Cosmic Ray Experiments COVER-PLASTEX and ARGO/YBJ. In both experiments the detectors were housed indoors, likely owing to gas distribution requirements and the need to control environment variables that directly affect RPCs operational stability. But in experiments where Extended Air Shower (EAS) sampling is necessary, large area arrays composed by dispersed stations are deployed, rendering this kind of approach impossible. In this situation, it would be mandatory to have detectors that could be deployed in small standalone stations, with very rare opportunities for maintenance, and with good resilience to environmental conditions. Aiming to meet these requirements, we started some years ago the development of RPCs for Autonomous Stations. The results from indoor tests and measurements were very promising, both concerning performance and stability under very low gas flow rate, which is the main requirement for Autonomous Stations. In this w...

    Griner, Carolyn S.

    1990-01-01

    The concept for utilization and operations planning for the International Space Station Freedom was developed in a NASA Space Station Operations Task Force in 1986. Since that time the concept has been further refined to definitize the process and products required to integrate the needs of the international user community with the operational capabilities of the Station in its evolving configuration. The keystone to the process is the development of individual plans by the partners, with the parameters and formats common to the degree that electronic communications techniques can be effectively utilized, while maintaining the proper level and location of configuration control. The integration, evaluation, and verification of the integrated plan, called the Consolidated Operations and Utilization Plan (COUP), is being tested in a multilateral environment to prove out the parameters, interfaces, and process details necessary to produce the first COUP for Space Station in 1991. This paper will describe the concept, process, and the status of the multilateral test case.

    2012-01-01

    Our aim is to assess the benefits and limitations of using the redundant visibility information in regular phased array systems for improving the calibration. Regular arrays offer the possibility to use redundant visibility information to constrain the calibration of the array independent of a sky model and a beam models of the station elements. It requires a regular arrangement in the configuration of array elements and identical beam patterns. We revised a calibration method for phased array stations using the redundant visibility information in the system and applied it successfully to a LOFAR station. The performance and limitations of the method were demonstrated by comparing its use on real and simulated data. The main limitation is the mutual coupling between the station elements, which leads to non-identical beams and stronger baseline dependent noise. Comparing the variance of the estimated complex gains with the Cramer-Rao Bound (CRB) indicates that redundancy is a stable and optimum method for cali...

    The NASA study activities in preparation for a Space Station began in the early 1970's. The early studies included many in-house NASA and contracted studies. A group of representatives from all the NASA Centers, titled the Space Station Concept Development Group (CDG) was involved in the studies which led to the initiation of the Space Station Program. The CDG studies were performed over a period of approximately one year and consisted of four phases. The initial phase had the objective to determine the functions required of the station as opposed to a configuration. The activities of the second phase were primarily concerned with a sizing of the facilities required for payloads and the resources necessary to support these mission payloads. The third phase of studies was designed to develop a philosophical approach to a number of areas related to autonomy, maintainability, operations and logistics, and verification. The fourth phase of the study was to be concerned with configuration assessment activities.

    Pumping station supplies water for technological process. The check valve in the station was replaced with a new one. The regular test of black out discovered the high pressure pulsations accompanied with noticeable pipeline movement of discharge pipe. It was caused by late check valve closing, probably, when the back flow reached the highest possible velocity. This statement was supported with analysis of results of pressure measurement near the check valve and with a numerical simulation of the flow in the pipeline system.

  19. Compression station anti-surge system considerations

    Kurz, Rainer; White, Robert C. [Solar Turbines Incorporated, Houston, TX (United States)

    2005-07-01

    Centrifugal compressor surge and its prevention have drawn significant attention in the literature. An important aspect of surge avoidance lies in the design of the compressor station and, in particular, the piping upstream and downstream of the compressor. Most anti-surge systems are perfectly capable of avoiding surge during normal operating conditions. However, unplanned emergency shutdowns present a significant challenge, and surge avoidance in these cases depends to a large degree on the station layout. Furthermore, the concepts used in the anti surge system (valves, piping, coolers) also impact the start-up of the station, or of individual units of the station. In this paper a simplified surge control system model is presented and used to develop simpler rules that help with proper sizing of upstream and downstream piping systems, as well as the necessary control element. Since the design of the surge control and recycle system also affects the start-up of units and stations, start-up considerations for stations with and without cooled recycle loops are discussed.

    1987-02-01

    Documentation is provided for a microcomputer program which was developed to evaluate the effect of the vibroacoustic environment on speech communication inside a space station. The program, entitled Space Station Interior Noise Analysis Program (SSINAP), combines a Statistical Energy Analysis (SEA) prediction of sound and vibration levels within the space station with a speech intelligibility model based on the Modulation Transfer Function and the Speech Transmission Index (MTF/STI). The SEA model provides an effective analysis tool for predicting the acoustic environment based on proposed space station design. The MTF/STI model provides a method for evaluating speech communication in the relatively reverberant and potentially noisy environments that are likely to occur in space stations. The combinations of these two models provides a powerful analysis tool for optimizing the acoustic design of space stations from the point of view of speech communications. The mathematical algorithms used in SSINAP are presented to implement the SEA and MTF/STI models. An appendix provides an explanation of the operation of the program along with details of the program structure and code.

    DOE Technical Standard HDBK-1216-2015 (DOE 2015) recommends evaluating air-monitoring station placement using the analytical method developed by Waite (Waite, 1973). The technique utilizes wind rose and population distribution data in order to determine a weighting factor for each directional sector surrounding a nuclear facility. Based on the available resources (number of stations) and a scaling factor, this weighting factor is used to determine the number of stations recommended to be placed in each sector considered. An assessment utilizing this method was performed in 2003 to evaluate the effectiveness of the existing SRS air-monitoring program. The resulting recommended distribution of air-monitoring stations was then compared to that of the existing site perimeter surveillance program (Fledderman 2003). The assessment demonstrated that the distribution of air-monitoring stations at the time generally agreed with the results obtained using the Waite method; however at the time new stations were established in Barnwell and in Williston in order to meet requirements of DOE guidance document EH-0173T.

    Full Text Available Os métodos atualmente utilizados para realização de análise sensorial têm deixado muito a desejar por não traduzir satisfatoriamente os resultados. 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. Because of this problem, it was analyzed the possibility of introducing a factor that measures the agreement index of the tasters on a particular aspect analyzed. To validate this coefficient, the agreement coefficient among the sensory analysis tasters had been evaluated using three different annona samples; one consisting only of the annona juice (without milk and the other with different concentrations of juice / milk (mass percentage. This evaluation was accomplished by the Analysis of Main Components (ACP and by the new methodology also proposed by the authors, with base in the

    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. This situation has improved, in recent years, to maintain cooperatives' organizational competition level in markets. Owing to the significant implications of this important new business environment, this paper tries to discuss the tools to reduce the

    2015-01-01

    The growth and development of the mobile phone network has led to an increased demand for energy by the telecommunications sector, with a noticeable impact on the environment. Monitoring of energy consumption is a great tool for understanding how to better manage this consumption and find the best strategy to adopt in order to maximize reduction of unnecessary usage of electricity. This paper reports on a monitoring campaign performed on six Base Transceiver Stations (BSs) located central Italy, with different technology, typology and technical characteristics. The study focuses on monitoring energy consumption and environmental parameters (temperature, noise, and global radiation), linking energy consumption with the load of telephone traffic and with the air conditioning functions used to cool the transmission equipment. Moreover, using experimental data collected, it is shown, with a Monte Carlo simulation based on power saving features, how the BS monitored could save energy.

    Modern systems such as fly-by-wire aircraft, nuclear power plants, manufacturing facilities, battlefields, etc., are all examples of highly connected network enabled systems. Many of these systems are also mission critical and need to be monitored round the clock. Such systems typically consist of embedded sensors in networked subsystems that can transmit data to central (or remote) monitoring stations. Moreover, many legacy are safety systems were originally not designed for real-time onboard diagnosis, but a critical and would benefit from such a solution. Embedding additional software or hardware in such systems is often considered too intrusive and introduces flight safety and validation concerns. Such systems can be equipped to transmit the sensor data to a remote-processing center for continuous health monitoring. At Qualtech Systems, we are developing a Remote Diagnosis Server (RDS) that can support multiple simultaneous diagnostic sessions from a variety of remote subsystems.

    1992-09-01

    Monthly precipitation data from 10 stations (Patras, Corfu, Hvar, Trieste, Venice, Florence, Rome, Naples, Catania and Malta) in the Central Mediterranean area are used for a period of 95 years (1894 1988). The homogeneity of these precipitation time series is tested and their statistical characteristics are analysed. An abrupt climatic change is found at Naples and Rome. The application of Principal Component Analysis (PCA) has yielded three groups of stations where the precipitation data indicate similar fluctuations. Group A includes the stations situated along the coasts of the Ionian and Adriatic seas and the station Naples, while Group B includes the Northern Italian stations and Group C includes the stations at Catania and Malta. In all three groups maximum precipitation was observed during the 1930s. The periodicities of the scores of the significant components have been studied by spectral analysis and significant periodicities of 13.6, 3.5 and 2.2 years were found. Finally, a discussion of the relationships between these precipitation fluctuations and circulation types over the Mediterranean is presented.

    Radiotherapy of brain lesions near critical structures requires a high accuracy in the location and dose. The high precision is achieved by the location of the stereotactic apparatus. The accuracy in dose delivery should be accompanied by an accurate quality control in devices that involve the practice, however, still does not guarantee the dose at the time of therapy. 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)

    Full Text Available Este trabalho demonstra os resultados preliminares, parciais, da experimentação e aceitação de uma metodologia para apresentação de imagens médicas, que utiliza programas simples, sem custo por serem "freewares", que podem ser utilizados em plataformas computacionais medianas, normalmente subutilizadas, não sendo necessários programas extensos, de alto custo, aprendizado dificultado pela sofisticação, tornando mais simples e acessível a possibilidade de visualização, apresentação, impressão, documentação, arquivamento, transmissão eletrônica e disponibilidade para consulta de uma gama de imagens médicas.We present the preliminary results of testing and acceptance of a method for displaying medical images that employs simple computer freewares that can be run in unsophisticated computational platforms, which are commonly underutilized. This method allows easy and accessible visualization, printing, documenting, archiving, consulting and electronic transmission of a wide range of medical images without the need of expensive, complex and difficult to learn softwares.

    Full Text Available O Restaurante Spoleto, em busca da sobrevivência, percebeu um nicho de mercado, optando assim por estratégias inovadoras, estabeleceu um novo conceito no segmento de alimentação fora de casa não sendo classificado como fast food, nem tão pouco restaurante, mas como food service. Através de um plano estratégico, a principio identificado como informal, o Restaurante Spoleto obteve como resultado a ampliação de 87 lojas em todo Brasil em seis anos. Seus principais atrativos incorrem em custos operacionais mais baixos que os restaurantes tradicionais; processos customizados e redução de mão-de-obra. O objetivo da pesquisa foi identificar o processo de planejamento da empresa e tentar enquadrá-lo dentro da metodologia de Certo e Peter com intuito de verificar se houve uma informalidade ou se este obedeceu algum padrão conceitual.

    Full Text Available A teoria dos jogos é uma abordagem matemática que estuda formalmente o conflito e a cooperação entre indivíduos. Trata-se de uma teoria científica suficientemente coerente para a construção de conhecimentos nas mais diversas áreas como Economia, Política, Biologia, Psicologia e Sociologia, pois possibilita a investigação de conflitos de interesses presentes na tomada de decisão entre cooperar e não. Apresentamos, neste artigo, sua aplicação para o estudo da cooperação descrevendo os jogos na sua aplicação em estudos evolucionistas. Concluímos que essa metodologia pode auxiliar os pesquisadores na compreensão dos mecanismos que nos levam a cooperar ou trapacear em nossas interações sociais. Trata-se de uma descrição teórica do que vem a ser a teoria dos jogos e exemplos de aplicação

    In this paper a thermal performance analysis of solar drying process at operating varying conditions is presented. It is described semi-empirical models to thermal characterization of an experimental device. A simulator of thermal performance for operating varying conditions was developed as a part of the procedure of thermal design of solar dryers. On the other hand, it is described a simplified method to design solar collectors based on the determination of minimum entropy generation during the thermal conversion of the solar device by using the thermal analysis procedure established and the method derived of the second law of the Thermodynamics are finally presented. [Spanish] En este trabajo se presenta el analisis termico del comportamiento del sistema -colector solar camara de secado-. Se describen los modelos semi-empiricos con los que se caracterizo termicamente un secador solar experimental del tipo indirecto. Se presenta tambien un procedimiento de diseno de equipo de secado que toma en cuenta las condiciones variables de operacion que presentan los dispositivos solares. Por otro lado se describe un procedimiento simplificado de diseno, basado en un analisis derivado de la segunda ley de la Termodinamica. Esta metodologia se fundamenta en la minima generacion de entropia durante la conversion termica de la energia solar, utilizando colectores solares planos. Finalmente se presentan los resultados del diseno preliminar de equipo de secado utilizando los dos procedimientos mencionados.

    Full Text Available As práticas e os projetos pedagógicos dos cursos da área da saúde têm sido alvo de intervenções a fim de se contemplarem as necessidades da sociedade contemporânea. A formação do farmacêutico não foge a esta linha, na qual se destaca a correlação entre teoria e prática, ressaltando a necessidade de uma visão integral do indivíduo e do meio que o cerca. Com base nestas considerações, o presente artigo visa abordar a utilização de metodologias ativas de ensino-aprendizagem na disciplina de Assistência e Atenção Farmacêutica do curso de Farmácia do Centro Universitário Franciscano (UNIFRA, relatando avanços e dificuldades observadas. Foram realizados, semestralmente, sete estudos de caso abordando problemas de saúde, farmacoterapia e problemas relacionados a medicamentos. Como resultados, destaca-se a formação de um aluno capaz de intervir e construir o próprio futuro com responsabilidade e comprometimento com a formação humanística e generalista.

    Full Text Available O presente texto apresenta reflexões e contribuições a partir das aproximações entre a Teoria Pedagógica Histórico-Critica e o trato com o conhecimento da Cultura Corporal mediada pela metodologia específica de ensino da Educação Física denominada Crítico-Superadora. Parte da consideração da Cultura Corporal como categoria teórica que nos permite apreender no pensamento, compreender, explicar cientificamente o real concreto, sendo, portanto, um objeto de estudo e ensino que se compõe de outros objetos de estudo e ensino – Esporte, Jogo, Dança, Ginástica, Luta, entre outros –, o que nos permite, uma vez apreendida sua estrutura lógico-histórica, propor, em especial no sistema educacional, como tratar o conhecimento específico da cultura corporal na escola e nas aulas de Educação Física, visando elevar o pensamento teórico dos estudantes, na perspectiva da emancipação humana e da omnilateralidade.  http://dx.doi.org/10.14572/nuances.v27i1.3962
