    1. Variation in climate is predicted to increase over much of the planet this century. Forecasting species persistence with climate change thus requires understanding of how populations respond to climate variability, and the mechanisms underlying this response. Variable rainfall is well known to drive fluctuations in annual plant populations, yet the degree to which population response is driven by between-year variation in germination cueing, water limitation or competitive suppression is poorly understood. 2. We used demographic monitoring and population models to examine how three seed banking, rare annual plants of the California Channel Islands respond to natural variation in precipitation and their competitive environments. Island plants are particularly threatened by climate change because their current ranges are unlikely to overlap regions that are climatically favourable in the future. 3. Species showed 9 to 100-fold between-year variation in plant density over the 5-12 years of censusing, including a severe drought and a wet El Nin??o year. During the drought, population sizes were low for all species. However, even in non-drought years, population sizes and per capita growth rates showed considerable temporal variation, variation that was uncorrelated with total rainfall. These population fluctuations were instead correlated with the temperature after the first major storm event of the season, a germination cue for annual plants. 4. Temporal variation in the density of the focal species was uncorrelated with the total vegetative cover in the surrounding community, suggesting that variation in competitive environments does not strongly determine population fluctuations. At the same time, the uncorrelated responses of the focal species and their competitors to environmental variation may favour persistence via the storage effect. 5. Population growth rate analyses suggested differential endangerment of the focal annuals. Elasticity analyses and life

  9. Historical plant cost and annual production expenses for selected electric plants, 1982

    International Nuclear Information System (INIS)

    This publication is a composite of the two prior publications, Hydroelectric Plant Construction Cost and Annual Production Expenses and Thermal-Electric Plant Construction Cost and Annual Production Expenses. Beginning in 1979, Thermal-Electric Plant Construction Cost and Annual Production Expenses contained information on both steam-electric and gas-turbine electric plant construction cost and annual production expenses. The summarized historical plant cost described under Historical Plant Cost in this report is the net cumulative-to-date actual outlays or expenditures for land, structures, and equipment to the utility. Historical plant cost is the initial investment in plant (cumulative to the date of initial commercial operation) plus the costs of all additions to the plant, less the value of retirements. Thus, historical plant cost includes expenditures made over several years, as modifications are made to the plant. Power Production Expenses is the reporting year's plant operation and maintenance expenses, including fuel expenses. These expenses do not include annual fixed charges on plant cost (capital costs) such as interest on debt, depreciation or amortization expenses, and taxes. Consequently, total production expenses and the derived unit costs are not the total cost of producing electric power at the various plants. This publication contains data on installed generating capacity, net generation, net capability, historical plant cost, production expenses, fuel consumption, physical and operating plant characteristics, and other relevant statistical information for selected plants

  14. Tree Mortality Undercuts Ability of Tree-Planting Programs to Provide Benefits: Results of a Three-City Study

    Directory of Open Access Journals (Sweden)

    Sarah Widney

    2016-03-01

    Full Text Available Trees provide numerous benefits for urban residents, including reduced energy usage, improved air quality, stormwater management, carbon sequestration, and increased property values. Quantifying these benefits can help justify the costs of planting trees. In this paper, we use i-Tree Streets to quantify the benefits of street trees planted by nonprofits in three U.S. cities (Detroit, Michigan; Indianapolis, Indiana, and Philadelphia, Pennsylvania from 2009 to 2011. We also use both measured and modeled survival and growth rates to “grow” the tree populations 5 and 10 years into the future to project the future benefits of the trees under different survival and growth scenarios. The 4059 re-inventoried trees (2864 of which are living currently provide almost $40,000 (USD in estimated annual benefits ($9–$20/tree depending on the city, the majority (75% of which are increased property values. The trees can be expected to provide increasing annual benefits during the 10 years after planting if the annual survival rate is higher than the 93% annual survival measured during the establishment period. However, our projections show that with continued 93% or lower annual survival, the increase in annual benefits from tree growth will not be able to make up for the loss of benefits as trees die. This means that estimated total annual benefits from a cohort of planted trees will decrease between the 5-year projection and the 10-year projection. The results of this study indicate that without early intervention to ensure survival of planted street trees, tree mortality may be significantly undercutting the ability of tree-planting programs to provide benefits to neighborhood residents.

  15. Damage costs produced by electric power plants: an externality valuation in the Mexico City Metropolitan Area.

    Science.gov (United States)

    Macías, P; Islas, J

    2010-09-15

    This paper presents an estimate of the externalities produced in the Mexico City Metropolitan Area (MCMA) through the impacts on health caused by secondary pollutants attributed to seven electric power plants located outside this area. An original method was developed to make possible a simplified application of the impact pathway approach to estimate the damage costs in the specified area. Our estimate shows that the annual costs attributed to secondary pollutants total 71 million USD (min/max 20/258 million USD). Finally, this paper discusses basic ideas on the implications for energy policy arising from this exercise in externality valuation.

  3. Annual City Festivals as Tools for Sustainable Competitiveness: The World Port Days Rotterdam

    Directory of Open Access Journals (Sweden)

    Erwin van Tuijl

    2016-05-01

    Full Text Available Many cities organize annual local festivals for the positive effects on urban development, although success is far from straightforward. This article reviews a case study of the World Port Days in Rotterdam in order to demonstrate how annual city festivals can contribute to sustainable competitiveness, despite limitations as well. We show how this maritime event—that is jointly organized by the business community, the Port Authority and the City Government—offers benefits for citizens as well as for firms. Our empirical results unveil that the business value of the event includes generation of societal support, image improvement, labor market development and networking, while the value for society refers to education, leisure and to a certain degree to social inclusion. The direct value of the event for business in terms of sales and recruitment is limited, while the long-term effects of educational function deserve further attention. Finally, we provide policy lessons that, when properly contextualized, other cities may help to use annual local festivals as tools for sustainable competitiveness.

    Full Text Available This paper examines the long-term urban modification of mean annual conditions of near surface temperature in Nairobi City. Data from four weather stations situated in Nairobi were collected from the Kenya Meteorological Department for the period from 1966 to 1999 inclusive. The data included mean annual maximum and minimum temperatures, and was first subjected to homogeneity test before analysis. Both linear regression and Mann-Kendall rank test were used to discern the mean annual trends. Results show that the change of temperature over the thirty-four years study period is higher for minimum temperature than maximum temperature. The warming trends began earlier and are more significant at the urban stations than is the case at the sub-urban stations, an indication of the spread of urbanisation from the built-up Central Business District (CBD to the suburbs. The established significant warming trends in minimum temperature, which are likely to reach higher proportions in future, pose serious challenges on climate and urban planning of the city. In particular the effect of increased minimum temperature on human physiological comfort, building and urban design, wind circulation and air pollution needs to be incorporated in future urban planning programmes of the city.

    Full Text Available The total area of green spaces in the capital of Dagestan now stands at 3003.5 hectare, and in the mid-1960s - 186 hectares. Green areas of common use per capita in 2015 compared to 1960 has decreased dramatically and amounted to 3.6%, which is only 1.0% of the norm. The race of landscape construction of the city far behind the race of construction of residential and office sectors, and the existing green spaces either in quantity or quality does not matches the sanitary and aesthetic requirements, in addition there is a low level of artistic and architectural planning of green space. We have also described the questions of the history of the garden and the park building in Makhachkala and meticulously analyzed the rock-species (species, forms, varieties of the composition of green space. We have marked the evaluation of their condition. Despite the great diversity of species composition (281 kind of woody plants, including 60 species of gymnosperms and angiosperms 221 views, we have noticed that almost everywhere there was cultivated only a small part of them. This is despite the fact, that the Republic of Dagestan has a rich species diversity of local flora, which can be effectively used in landscaping. Here, too, there are favorable climatic conditions for the introduction of new species. It should be noted that the private sector can be traced as having the opposite trend. Some recommendations have been given to improve the structure and condition of the trees and bushes planted in the city. Finally, we have shown the necessity of linking the production of green building works with the scientific activities of specialized education and research institutions in the city

    Full Text Available Although a few studies on rainfall spatial and temporal variability in the UAE have been carried out, evidence of the impact of climate change on rainfall trends has not been reported. This study aims at assessing the significance of long-term rainfall trends and temporal variability at Sharjah City, UAE. Annual rainfall and seasonal rainfall extending over a period of 81 years (1934–2014 recorded at Sharjah International Airport have been analyzed. To this end, several parametric and nonparametric statistical measures have been applied following systematic data quality assessment. The analyses revealed that the annual rainfall trend decreased from −3 mm to −9.4 mm per decade over the study periods. The decreasing annual rainfall trend is mainly driven by the significant drop in winter rainfall, particularly during the period from 1977 to 2014. The results also indicate that high probability extreme events have shifted toward low frequency (12.7 years with significant variations in monthly rainfall patterns and periodicity. The findings of the present study suggest reevaluating the derivation of design rainfall for infrastructure of Sharjah City and urge developing an integrated framework for its water resources planning and risk under climate change impacts scenarios.

    This work presents indoor radon measurements in 42 dwellings in the city of Megalopolis, Southern Greece, located in the vicinity of 2 lignite-fired power plants and examines the effect of season, floor level and age of the dwellings on indoor radon concentration. The radon measurements have been carried out using the LR-115, type II and CR-39 alpha track detectors in 'closed-can' geometry. The average annual indoor radon concentration (GM) was found to be 52 Bq m{sup -3}, which is well below the recommended action level of the European Union. This value corresponds to an annual effective dose to the population of 1.3 {+-} 0.4 mSv. Season and age of the examined dwellings represent factors that affected significantly the indoor radon in Megalopolis, while the effect of floor level appeared to be not significant. Radium activity concentration values, measured by gamma-ray spectrometry in 20 sub-samples of six soil cores (60-135 cm depth), collected from the surrounding area of the city, were found to be consistent with the Greek and world average values. Based on the results of this study, it is concluded that the effect of the lignite-fired power plants on indoor radon concentration in Megalopolis' dwellings was not significant.

    Full Text Available One strategy to protect land from degradation is to use the land according to their capability. Zoning of commodities is an effort in that direction and determination of commodities is based on the suitability of land with agronomic needs of crops and farming feasibility analysis. The purpose of this study was to determine the development zone of annual crops, based on the analysis of agro-ecological characteristics and agricultural viability. Analysis of land suitability for the cultivation of coffee, vanilla, pepper, cocoa, banana, durian, mango, and melinjo, found that land can be recommended for the development of the annual crops is about 29,230 ha from an area of 54,764 ha. The land was divided into six agro-ecological zones i.e. two zones at area with land slope of 3- 8%, each covering an area of 2,737 ha at an altitude of 15-50 m above sea level (asl, and 12,008 ha at an altitude of 50-300 m asl, the two zone at area with land slope of 8-15%, each covering 6119 ha at an altitude of 25-250 m asl and 1,221 ha at an altitude of 15-50 m asl, and two zones at area with land slope of 16-40% , each covering an area of 1,101 ha at an altitude of 400-700 m asl, and 6,134 ha at an altitude of 400-500 m asl. The soil types found are Typic /Vitrandic Eutrudepts, Typic Hapludands, and Vitrandic Hapludalfs. This study recommends that the banana is a perennial plant with the most potential to be developed and has good economic prospects in almost all agro-ecological zones. Other commodities are also preferred, coffee and vanilla.

  4. Implementation of deep soil mixing at the Kansas City Plant

    International Nuclear Information System (INIS)

    In July 1996, the US Department of Energy (DOE) Kansas City Plant (KCP), AlliedSignal Federal Manufacturing and Technologies, and Oak Ridge National Laboratory (ORNL), conducted field-scale tests of in situ soil mixing and treatment technologies within the Northeast Area (NEA) of the KCP at the Former Ponds site. This demonstration, testing, and evaluation effort was conducted as part of the implementation of a deep soil mixing (DSM) innovative remedial technology demonstration project designed to test DSM in the low-permeability clay soils at the KCP. The clay soils and groundwater beneath this area are contaminated by volatile organic compounds (VOCs), primarily trichloroethene (TCE) and 1,2-dichloroethene (1,2-DCE). The demonstration project was originally designed to evaluate TCE and 1,2-DCE removal efficiency using soil mixing coupled with vapor stripping. Treatability study results, however, indicated that mixed region vapor stripping (MRVS) coupled with calcium oxide (dry lime powder) injection would improve TCE and 1,2-DCE removal efficiency in saturated soils. The scope of the KCP DSM demonstration evolved to implement DSM with the following in situ treatment methodologies for contaminant source reduction in soil and groundwater: DSM/MRVS coupled with calcium oxide injection; DSM/bioaugmentation; and DSM/chemical oxidation using potassium permanganate. Laboratory treatability studies were started in 1995 following collection of undisturbed soil cores from the KCP. These studies were conducted at ORNL, and the results provided information on optimum reagent concentrations and mixing ratios for the three in situ treatment agents to be implemented in the field demonstration

    Human drivers are often proposed to be stronger than biophysical drivers in influencing ecosystem structure and function in highly urbanized areas. In residential land cover, private yards are influenced by individual homeowner preferences and actions while also experiencing large-scale human and biophysical drivers. We studied plant nitrogen (%N) and N stable isotopic composition (δ(15)N) in residential yards and paired native ecosystems in seven cities across the US that span major ecological biomes and climatic regions: Baltimore, Boston, Los Angeles, Miami, Minneapolis-St. Paul, Phoenix, and Salt Lake City. We found that residential lawns in three cities had enriched plant δ(15)N (P fertilization was associated with depleted plant δ(15)N in Boston and Los Angeles (P organic fertilizer additions were associated with enriched plant δ(15)N in Los Angeles and Salt Lake City (P < 0.04). Plant δ(15)N was significantly enriched as a function of housing age in Baltimore (r (2) = 0.27, P < 0.02), Boston (r (2) = 0.27, P < 0.01), and Los Angeles (r (2) = 0.34, P < 0.01). These patterns in plant δ(15)N and plant N (%) across these cities suggests that N sources to lawns, as well as greater rates of N cycling combined with subsequent N losses, may be important drivers of plant N dynamics in lawn ecosystems at the national scale.

    2014-07-01

    The maximum value of tritium concentration in precipitation was 200 Bq/kg in Niigata city when atmospheric nuclear-bomb tests were performed in 1960s. After that, tritium concentration continuously decreased and reached to environmental revel (0.5~1.0 Bq/kg). However, after the accident of Fukushima daiichi nuclear power plants, the tritium concentration in precipitation increased in Niigata city. Therefore the observation of tritium concentration had to be carried out. In our laboratory, we have investigated the tritium concentration in precipitation and also investigated the relation between the tritium concentration and other ion (Na⁺, Mg⁺, K⁺, Ca⁺, Cl⁻, NO3⁺ or SO₄²⁻) concentration in precipitation in Niigata city. In this study, precipitation in Niigata city was gathered monthly and the evaluation of tritium concentration in precipitation was performed. In addition, we also collected the precipitation hourly (short precipitation). Each water sample thus obtained was distilled with sodium peroxide and potassium permanganate. Then the water sample thus distilled was enriched in SPE electronic enrichment apparatus, and the tritium concentration in the sample thus treated was measured in a liquid scintillation counter. On the other hand, each ion concentration in the sample was measured by ion chromatography or Atomic Absorption Spectrometry. From the above the mentioned, the following five matters can be found. (1) The tritium concentration in the samples in March and April 2011 were twice or three times higher than that in March and April in annual years. In other words, it is considered that the thus high level concentration of tritium leads to the evaluation of the effect of the accident of the Fukushima nuclear power plants on Niigata city. (2) As to the sample, the concentration of the non-sea salt Ca²⁺ (nssCa²⁺) is similar to that in March and April in annual years. (3) For each short precipitation sample collected on March 15, 2011

  20. An Annual Plant Growth Proxy in the Mojave Desert Using MODIS-EVI Data

    Full Text Available In the arid Mojave Desert, the phenological response of vegetation is largely dependent upon the timing and amount of rainfall, and maps of annual plant cover at any one point in time can vary widely. Our study developed relative annual plant growth models as proxies for annual plant cover using metrics that captured phenological variability in Moderate-Resolution Imaging Spectroradiometer (MODIS Enhanced Vegetation Index (EVI satellite images. We used landscape phenologies revealed in MODIS data together with ecological knowledge of annual plant seasonality to develop a suite of metrics to describe annual growth on a yearly basis. Each of these metrics was applied to temporally-composited MODIS-EVI images to develop a relative model of annual growth. Each model was evaluated by testing how well it predicted field estimates of annual cover collected during 2003 and 2005 at the Mojave National Preserve. The best performing metric was the spring difference metric, which compared the average of three spring MODIS-EVI composites of a given year to that of 2002, a year of record drought. The spring difference metric showed correlations with annual plant cover of R2 = 0.61 for 2005 and R2 = 0.47 for 2003. Although the correlation is moderate, we consider it supportive given the characteristics of the field data, which were collected for a different study in a localized area and are not ideal for calibration to MODIS pixels. A proxy for annual growth potential was developed from the spring difference metric of 2005 for use as an environmental data layer in desert tortoise habitat modeling. The application of the spring difference metric to other imagery years presents potential for other applications such as fuels, invasive species, and dust-emission monitoring in the Mojave Desert.

  1. City of Klamath Falls, Oregon Geothermal Power Plant Feasibility Study

    2011-07-31

    The purpose of the Klamath Falls project is to demonstrate the effectiveness of a combined thermal distribution system and power generation facility. The city of Klamath Falls operates a geothermal district heating system which would appear to be an attractive opportunity to install a power generation system. Since the two wells have operated reliably and consistently over many years, no new sources or resource exploration would be necessary. It appears that it will cost more to construct, operate, maintain and amortize a proposed geothermal facility than the long?term value of the power it would produce. The success of a future project will be determined by whether utility power production costs will remain low and whether costs of construction, operations, or financing may be reduced. There are areas that it would be possible to reduce construction cost. More detailed design could enable the city to obtain more precise quotes for components and construction, resulting in reduction in contingency projections. The current level of the contingency for uncertainty of costs is between $200,000 and $300,000. Another key issue with this project appears to be operation cost. While it is expected that only minimal routine monitoring and operating expenses will occur, the cost of water supply and waste water disposal represents nearly one quarter of the value of the power. If the cost of water alone could be reduced, the project could become viable. In addition, the projected cost of insurance may be lower than estimated under a city?wide policy. No provisions have been made for utilization of federal tax incentives. If a transaction with a third-party owner/taxpayer were to be negotiated, perhaps the net cost of ownership could be reduced. It is recommended that these options be investigated to determine if the costs and benefits could be brought together. The project has good potential, but like many alternative energy projects today, they only work economically if the

    The arbuscular mycorrhizal fungi (AMF) communities composition regulate plant interactions and determine the structure of plant communities. In this study we analysed the diversity of AMF in the roots of two perennial gypsophyte plant species, Herniaria fruticosa and Senecio auricula, and an annual herbaceous species, Bromus rubens, growing in a gypsum soil from a semiarid area. The objective was to determine whether perennial and annual host plants support different AMF communities in their roots and whether there are AMF species that might be indicators of specific functional plant roles in these ecosystems. The roots were analysed by nested PCR, cloning, sequencing of the ribosomal DNA small subunit region and phylogenetic analysis. Twenty AMF sequence types, belonging to the Glomus group A, Glomus group B, Diversisporaceae, Acaulosporaceae, Archaeosporaceae and Paraglomeraceae, were identified. Both gypsophyte perennial species had differing compositions of the AMF community and higher diversity when compared with the annual species, showing preferential selection by specific AMF sequences types. B. rubens did not show host specificity, sharing the full composition of its AMF community with both perennial plant species. Seasonal variations in the competitiveness of AM fungi could explain the observed differences in AMF community composition, but this is still a working hypothesis that requires the analysis of further data obtained from a higher number of both annual and perennial plant species in order to be fully tested.

  4. Ecological adaptation strategies of annual plants in artificial vegetation-stabilized sand dune in Shapotou Region

    Taking annual plant Eragrostis poaeides in the artificial vegetation-stabilized sand dune in the Shapotou Experimental Research Station as example, study has been done on the adaptation strategies of annual plants to random environment through fixed quadrat observations of population changes and fixed plant determinations of individual growth, seed germination,population dynamics, spatial distribution pattern of population, competition and regulation. During the growing season, the survival rate of annual plants depends on the precipitation intensity and precipitation duration which activate the germination of seeds. The optimal germination strategy of annual plants in this habitat during the growing season appears as continuous germination under suitable conditions. Such continuous germination is an adaptive characteristic of annual plants to random environment. In addition, the variation processes of population size and regulation mechanism of E. poaeoides are studied. Statistical results of natural population in four consecutive years show that water condition in the habitat is the leading factor affecting the population dynamics of E. poaeoides. During the establishment period E. poaeoides had a higher death rate, but in the middle to later period they could survive stably. Due to the limitation of soil moisture, the competition among individuals for water inevitably led to self-thinning phenomena. Under very arid condition, the survival curve of annual herbs entirely appears as Deevey Ⅲ type (C type), but under relatively adequate precipitation condition, the survival curve appears as intermediate type. The strategy of life history obviously appears as r-strategy. Plant species of r-strategy often occurs in the early succession stage of the communities. In the relatively adequate and evenly-distributed rainfall years, E. poaeoides population exhibited a density-dependent, i. e., survival rate increased with decrease in population density. The main pattern to

    International Nuclear Information System (INIS)

    The Swedish-Danish Barsebaeck committee suggested in June 1983 that a demographic comparison of the Barsebaeck nuclear power plant be made with plants situated near other large cities and national borders. Sixteen other nuclear power plants: 13 in Western Europe, 2 in USA and 1 in Canada were chosen for the comparison. For five discrete distances out to 50 km, the population distributions have been found and compared. In addition the positions, related to the plants, of institutions, administrative centres, communication centres and other plants of public importance within the country or in neughbouring countries are described. Finally, the details of special agreements are given together with negotiations between neighbouring countries or internationally about nuclear power related matters. These include alarm and emergency procedures and agreements about liability in case of an accident in a neighbouring country. (author)

    Regressive formulae to calculate the quantity of plant leaf area for 13 species of ornamental plants were set up based on investigation data of 30 species on 3 major public squares (Dongfeng square, Shengli square and Guandu square) in Kunruing City, China, which were applied to calculate quantities of plant leaf area of these 13 species. The quantities of plant leaf area for the other 17 ornamental plant species on these squares were directly measured, and the total quantity of plant leaf area of each studied square was obtained individually. The results showed that the quantity of plant leaf area on Shengli square with ornamental plants structure composed of arbor tree species, shrub tree species and turf grass was highest among the three squares. It is believed that the design model of multi-storied vertical structure and proper tending of plant community could not only increase the quantity of plant leaf area, but also play an important role in generating ecological and landscaping benefits.Some corresponding suggestions were put forward on the basis of comprehensive analyses on the plant leaf area quantity of the three representative squares in Kunming urban area.

  18. A simple tool for estimating city-wide annual electrical energy savings from cooler surfaces

    Energy Technology Data Exchange (ETDEWEB)

    Pomerantz, Melvin; Rosado, Pablo J.; Levinson, Ronnen M.

    2015-06-27

    We present a simple method to estimate the maximum possible electrical energy saving that might be achieved by increasing the albedo of surfaces in a large city. We restrict this to the “indirect effect”, the cooling of outside air that lessens the demand for air conditioning (AC). Given the power demand of the electric utilities and data about the city, we can use a single linear equation to estimate the maximum savings. For example, the result for an albedo change of 0.2 of pavements in a typical warm city in California, such as Sacramento, is that the saving is less than about 2 kWh per m2 per year. This may help decision makers choose which heat island mitigation techniques are economical from an energy-saving perspective.

  1. Siting of nuclear power plants and administration in cities, towns and villages

    International Nuclear Information System (INIS)

    For the siting problems, there are many explanations and documents from the side to construct nuclear power plants, but few which makes assertion from the side of accepting the plants. However, present difficulties in the siting problems of nuclear power plants cannot be solved if the assertion of the accepting side is neglected. The details from the start of the siting to now in Tsuruga city are described. It is tried to explain the situation with the documents expressing opinions, demands and petitions, and replies exchanged between Tsuruga city and the government, Fukui Prefecture, and the related power companies, and the related laws. The details include the failures and accidents of nuclear plants reported to date. The reasons why the mayors or headmen of towns or villages want to invite the nuclear power plants are that the development of their region can be expected, and favorable influence results in to the regional economy, and further they can cooperate with the national policy. However, opposition movements are the most embarrassing affairs for them, and it is due to the condition that they cannot give the satisfactory answer to the opposing people so far. They cannot but depend solely on the responsibility of the government to safety. On the organizations of cities, towns and villages accepting nuclear power plants and the influence on local community, detailed reports are presented using various documents on preparation, antidisaster plan, radiation monitoring organization, movement of population, the effects regarding tax system and finance, influence on the life of inhabitants and others.

    The purpose of this document is to summarize effluent monitoring and environmental surveillance results and compliance with environmental laws, regulations, and orders at the Paducah Gaseous Diffusion Plant (PGDP). Environmental monitoring at PGDP consists of two major activities: effluent monitoring and environmental surveillance. Effluent monitoring is direct measurement or the collection and analysis of samples of liquid and gaseous discharges to the environment. Environmental surveillance is direct measurement or the collection and analysis of samples of air, water, soil, foodstuff, biota, and other media. Environmental monitoring is performed to characterize and quantify contaminants, assess radiation exposures of members of the public, demonstrate compliance with applicable standards and permit requirements, and detect and assess the effects (if any) on the local environment. Multiple samples are collected throughout the year and are analyzed for radioactivity, chemical content, and various physical attributes

    In September of 1989 work began on the DOE University Program grant DE-FG07-89ER12889. The grant provides support for a three year project to develop and demonstrate Intelligent Distributed Control (IDC) for Nuclear Power Plants. The body of this Second Annual Technical Progress report covers the period from September 1990 to September 1991. It summarizes the second year accomplishments while the appendices provide detailed information presented at conference meetings. These are two primary goals of this research. The first is to combine diagnostics and control to achieve a highly automated power plant as described by M.A. Schultz, a project consultant during the first year of the project. This philosophy, as presented in the first annual technical progress report, is to improve public perception of the safety of nuclear power plants by incorporating a high degree automation where greatly simplified operator control console minimizes the possibility of human error in power plant operations. A hierarchically distributed control system with automated responses to plant upset conditions is the focus of our research to achieve this goal. The second goal is to apply this research to develop a prototype demonstration on an actual power plant system, the EBR-II steam plant.

    This research concerns the strong resistance, or even immunity, against a specific virus that is exhibited by one or a few lines of a plant species, in contrast to the general susceptibility of most lines of that species. The contrast between the reactions to virus inoculation of different lines of one species implies that a single gene or a very few genes may mediate the resistance or immunity. The prospects for isolating, studying and transferring such a gene should be good for a system with these characteristics. Seedlings of a line Arlington of the cowpea (Vigna unguiculata) fail to support the replication of cowpea mosaic virus strain SB (CPMV-SB). Genetic crosses of Arlington cowpea to the systemic host Blackeye 5 cowpea show that the immunity is inherited as a simple dominant gene. In contrast to the seedlings, the protoplasts of the Arlington cowpea support CPMV-SB replication, but only to a very low level compared to protoplasts of Blackeye 5 cowpeas. From evidence reported earlier we concluded that Arlington cowpea protoplasts restrict the production of CPMV-SB proteins. We postulated, and obtained evidence for, a proteinase inhibitor that is specific for a CPMV-SB proteinase. This proteinase inhibitor is our prime candidate for the mediator of the resistance of Arlington protoplasts to CPMV-SB. Progress to date is described.

    International Nuclear Information System (INIS)

    A research work was carried out during 2009-2011 to investigate the biomonitoring potential of a road avenue tree, Alstonia scholaris (L.) R.Br. against the culminating pressure of aerial pollution in Lahore city. For this purpose seven busiest roads were selected on the basis of the flux of traffic and three leaf samples were taken for various biochemical and physiological attributes from each of the A. scholaris tree of respective road. The geographic coordinates on the map can be used for future reference. Various floral attributes of plant were selected i.e., amount of dust (g), percent (%) leaf moisture content, photosynthetic rate (meu Mm-2S-1), transpiration rate (meu Mm-2S-1), stomatal conductance (meu Mm-2S-1), chlorophyll contents (mg/g) and amount of carotenoids (mg/g) in the leaf samples. In case of % leaf moisture content, significant variation between the control (61.95) and road side plants (50.76) was observed. While minute differences between the control and road side plants were recorded in photosynthetic rate, transpiration rate, stomatal conductance, chlorophyll contents and carotenoids, which is an indication that day by day increasing air pollution pressure in Lahore city is playing pivotal role, not only in the morphological features of the plant but also affecting the physiological and biochemical.

    Soil and plant samples were collected from roadside sites (along with primary, secondary and tertiary roads) and reference site to investigate the contamination of soils and old common plant species with lead (Pb) and cadmium (Cd) in Peshawar City, Pakistan. All the data were analyzed using ANOVA analysis that showed a significant (P ≤ 0.01) variation in Pb and Cd concentrations in the roadside soils and plants ss compared to the reference site. The mean concentrations of Pb and Cd were 53.9 and 6.0 mg kg-1 in soils and 49.1 and 10.9 mg kg-1 in plants, respectively. Significant variation (P ≤ 0.01) in concentrations of Pb and Cd in soil and plant samples along with primary, secondary and tertiary roads might be due to different traffic densities. The highest value (9.4) of metal accumulation index (MAI) was observed for Eucalyptus camaldulensis. In selected plant species, the Pb and Cd accumulation was found in the order of E. camaldulensis > Ficus elastica > Dalbergia sissoo > Alstonia scholaris. The roadside soils and plants were highly contaminated with Pb and Cd as compared to the reference site.

    Herbicide resistance is becoming more common in weed ecotypes and crop species including turfgrasses, but current gaps in knowledge limit predictive ecological risk assessments and risk management plans. This project examined the effect of annual glyphosate applications on the vegetative growth and reproductive potential of two weedy bentgrasses, creeping bentgrass (CB) and redtop (RT), where the glyphosate resistance (GR) trait was mimicked by covering the bentgrass plants during glyphosate application. Five field plots were studied in habitats commonly inhabited by weedy bentgrasses including an agricultural hayfield, natural meadow, and wasteland. Results showed that annual glyphosate treatment improved bentgrass survivorship, vegetative growth, and reproductive potential compared with bentgrass in unsprayed subplots. In the second year of growth, RT plants had an 86-fold increase in flower number in glyphosate-treated subplots versus controls, while CB plants had a 20-fold increase. At the end of the three year study, plant community composition had changed in glyphosate-treated subplots in hayfield and meadow plots compared to controls. Soils in subplots receiving glyphosate had higher nitrate concentrations than controls. This is the first study to mimic the GR trait in bentgrass plants with the goal of quantifying bentgrass response to glyphosate selection pressure and understanding the impacts on surrounding plant communities.

  16. Effect of Fukushima Daiichi Nuclear Power Plant accident on lakes in Fukushima Prefecture and Niigata City

    International Nuclear Information System (INIS)

    The Fukushima Daiichi Nuclear Power Plant Accident happened in 12 - 15th March 2011. This accident caused to the radioactive contamination in the near area. In this work, some lake waters and the sediments were collected in Fukushima Prefecture and Niigata City to clarify the effect of the accident on the area contaminated. As to the collected lake water, an enrichment of 'the specific activity of tritium (T specific activity)' in each water collected was carried out by the solid polymer electrolyte (SPE) apparatus, and the T specific activity was measured by a liquid scintillation counter. Based on the T specific activity thus measured, the influence of the accident to the environment was investigated. At the same time, specific activities of radioactive caesiums in the lake sediments were also measured. Consequently, the influence of the Fukushima Daiichi Nuclear Power Plant Accident to the adjacent lakes (e.g., in Fukushima Prefecture and Niigata City) was quantitatively clarified. From the above-mentioned matters, it is found that the effect of the accident on Niigata City is so small, and the accident gradually decreases in Fukushima Prefecture. (author)

  17. Complex consequences of herbivory and interplant cues in three annual plants.

    Directory of Open Access Journals (Sweden)

    Ian S Pearse

    Full Text Available Information exchange (or signaling between plants following herbivore damage has recently been shown to affect plant responses to herbivory in relatively simple natural systems. In a large, manipulative field study using three annual plant species (Achyrachaena mollis, Lupinus nanus, and Sinapis arvensis, we tested whether experimental damage to a neighboring conspecific affected a plant's lifetime fitness and interactions with herbivores. By manipulating relatedness between plants, we assessed whether genetic relatedness of neighboring individuals influenced the outcome of having a damaged neighbor. Additionally, in laboratory feeding assays, we assessed whether damage to a neighboring plant specifically affected palatability to a generalist herbivore and, for S. arvensis, a specialist herbivore. Our study suggested a high level of contingency in the outcomes of plant signaling. For example, in the field, damaging a neighbor resulted in greater herbivory to A. mollis, but only when the damaged neighbor was a close relative. Similarly, in laboratory trials, the palatability of S. arvensis to a generalist herbivore increased after the plant was exposed to a damaged neighbor, while palatability to a specialist herbivore decreased. Across all species, damage to a neighbor resulted in decreased lifetime fitness, but only if neighbors were closely related. These results suggest that the outcomes of plant signaling within multi-species neighborhoods may be far more context-specific than has been previously shown. In particular, our study shows that herbivore interactions and signaling between plants are contingent on the genetic relationship between neighboring plants. Many factors affect the outcomes of plant signaling, and studies that clarify these factors will be necessary in order to assess the role of plant information exchange about herbivory in natural systems.

    Based on the statistical theory, the paper collected routine monitoring data for 3 years of 11 municipal wastewater treatment plants with secondary treatment or enhanced secondary treatment in a northern city in China, and analysis of the discharge concentration distribution of COD showed a Delta-lognormal distribution. On this basis, referring to the formulation methods of water pollutant discharge limits used in the USA, the paper studied and assessed the discharge status of COD of the municipal wastewater treatment plants in the city, including the daily maximum and the monthly average discharge status, and came to the conclusion that the daily maximum discharge status met the first grade A class discharge standard (50 mg · L(-1)) required by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Meanwhile, the assessment conclusion was obtained for the monthly average discharge status, and the conclusions were discussed. The assessment method and the conclusions in this paper might provide reference for formulation and revision of water discharge standards. PMID:25693413

  2. A nuclear power plant for Lima city. Is it a real alternative?

    International Nuclear Information System (INIS)

    At the present, Peru has an installed electricity capacity of 4112 MW from which the 80% comes from hydroelectric sources and other 20% from thermal sources. Lima city concentrates the larger industrial activities and uses 95% of the hydro-electric supply the 5% comes from thermal origin. This situation provokes an energetic vulnerability to Lima, a city with more them 10 million of inhabitants, because climatic changes and the electric towers destruction. In the 1989-1992 period lack of energy meant economic losses for about US$ 2 100 000. To solve this problem the government is building a 300 MW thermal station. This alternative means a low investment for Kw installed but high production costs. Additionally the installation of the plant in Lima will increase the environmental contamination due to emission of about 20000 TM/year of SOx and 7500 TM/year of NOx. The research study recommends as a solution the diversification of energy sources, avoiding dependence of the hydro-electrical ones. In the same form it suggests that the next 300 MW power station to be installed for about 1998 would be a nuclear power plant but not thermal one. It also makes a revision of the new designs for nuclear power plants called safe inherently which design and construction philosophy avoid the possibility of accidents like Chernobyl.

  3. Using city-wide mobile noise assessments to estimate bicycle trip annual exposure to Black Carbon.

    Several studies have shown that a significant amount of daily air pollution exposure, in particular Black Carbon (BC), is inhaled during bicycle trips. Previously, the instantaneous BC exposure of cyclists was modeled as the sum of a background concentration and a local traffic related component based on a local assessment of traffic noise. We present a fast and low cost methodology to achieve a city-wide assessment of yearly average BC exposure of cyclists along their trips, based on a city-wide mobile noise sensing campaign. The methodology requires participatory sensing measurements of noise, partially combined with BC and/or other air pollutants sensitive to local traffic variations. The combined measurements cover the spatial and meteorological variability and provide the data for an instantaneous exposure model. The mobile noise-only measurements map the full city; and yearly meteorology statistics are used to extrapolate the instantaneous exposure model to a yearly average map of in-traffic air pollution exposure. Less than four passages at each segment along the network with mobile noise equipment are necessary to reach a standard error of 500 ng/m(3) for the yearly average BC exposure. A strong seasonal effect due to the BC background concentration is detected. The background contributes only 25% to the total trip exposure during spring and summer. During winter the background component increases to 50-60%. Engine related traffic noise along the bicyclist's route is a valid indicator of the BC exposure along the route, independent of the seasonal background. Low exposure route selection results in an exposure reduction of 35% in winter and 60% in summer, sensitive to the weather conditions, specific trip attributes and the available alternatives. The methodology is relevant for further research into the local effects of air pollution on health. Mobile noise mapping adds local traffic data including traffic dynamics into the air pollution exposure

    Long-term air quality data with high temporal and spatial resolutions are needed to understand some important processes affecting the air quality and corresponding environmental and health effects. The annual and diurnal variations of each criteria pollutant including PM2.5 and PM10 (particulate matter with aerodynamic diameter less than 2.5 μm and 10 μm, respectively), CO (carbon monoxide), NO2 (nitrogen dioxide), SO2 (sulfur dioxide) and O3 (ozone) in 31 provincial capital cities between April 2014 and March 2015 were investigated by cluster analysis to evaluate current air pollution situations in China, and the cities were classified as severely, moderately, and slightly polluted cities according to the variations. The concentrations of air pollutants in winter months were significantly higher than those in other months with the exception of O3, and the cities with the highest CO and SO2 concentrations were located in northern China. The annual variation of PM2.5 concentrations in northern cities was bimodal with comparable peaks in October 2014 and January 2015, while that in southern China was unobvious with slightly high PM2.5 concentrations in winter months. The concentrations of particulate matter and trace gases from primary emissions (SO2 and CO) and NO2 were low in the afternoon (~16:00), while diurnal variation of O3 concentrations was opposite to that of other pollutants with the highest values in the afternoon. The most polluted cities were mainly located in North China Plain, while slightly polluted cities mostly focus on southern China and the cities with high altitude such as Lasa. This study provides a basis for the formulation of future urban air pollution control measures in China.

  6. Is 'peak N' key to understanding the timing of flowering in annual plants?

    2015-01-01

    Flowering time in annual plants has large fitness consequences and has been the focus of theoretical and empirical study. Previous theory has concluded that flowering time has evolved over evolutionary time to maximize fitness over a particular season length. We introduce a new model where flowering is cued by a growth-rate rule (peak nitrogen (N)). Flowering is therefore sensitive to physiological parameters and to current environmental conditions, including N availability and the presence of competitors. The model predicts that, when overall conditions are suitable for flowering, plants should never flower after 'peak N', the point during development when the whole-plant N uptake rate reaches its maximum. Our model further predicts correlations between flowering time and vegetative growth rates, and that the response to increased N depends heavily on how this extra N is made available. We compare our predictions to observations in the literature. We suggest that annual plants may have evolved to use growth-rate rules as part of the cue for flowering, allowing them to smoothly and optimally adjust their flowering time to a wide range of local conditions. If so, there are widespread implications for the study of the molecular biology behind flowering pathways.

  8. Annual performance analysis of the solar chimney power plant in Sinkiang, China

    International Nuclear Information System (INIS)

    Highlights: • A theoretical model was developed concerning hourly variation of solar radiation. • A limitation on maximum collector radius of an SCPP with a given chimney exists. • Annual performance of a 100 MW SCPP was predicted in hourly interval. • The Hami region is considered suitable for the construction of SCPP. - Abstract: To obtain more accurate prediction of the annual performance of solar chimney power plants (SCPPs), a comprehensive theoretical model is developed by taking into account the hourly variation of solar radiation. The effects of the collector and chimney radii on the power output of the SCPP are analyzed, and the results reveal that a limitation on the maximum collector radius exists for the maximum attainable power output of the SCPP. Then four designs of 100 MW SCPPs with different combinations of collector and chimney radii are proposed and the most cost effective one is chosen from among the four SCPPs. The annual power output of the chosen SCPP in the Hami region is estimated at an interval of 1 h for a whole year. The results indicate that the power generation of SCPP presents obvious seasonal variation. Furthermore, the use of 14% of the unused land in the Hami region for the installation of SCPPs would satisfy the annual power requirement for the whole of the Sinkiang region

    Full Text Available In order to assess heavy metal pollution in the city of Belgrade (Serbia concentrations of V, Cr, Mn, Co, Ni, Cu, Zn, Cd and Pb were measured on 18 topsoil samples collected in the proximity to central urban boulevards and in urban parks. In addition, concentrations of specified elements were determined in leaves of three evergreen plant species Buxus sempervirens L., Mahonia aquifolium (Pursh Nutt. and Prunus laurocerasus L. so as to estimate their sensitivity to heavy metal pollution. Even though various types of soils from different quarts of Belgrade were sampled, their heavy metal contents were very similar, with somewhat higher concentrations of almost all elements detected in the proximity to high traffic roads. Generally, concentrations of heavy metals in leaves of investigated plant species paralleled the heavy metal concentrations found in their respective soils and were higher in plants sampled from boulevards then from urban parks. Since investigated plant show no visible injuries induced by detected heavy metal pollution these species are suitable for the successful urban landscaping.

    We studied recovery of winter annual plants in a 97-m wide disturbed aqueduct corridor in the Mojave Desert 36 years after construction. We established plots at 0, 20, and 40 m from the road verge at the corridor center and at 100 m in undisturbed vegetation. We recorded 47 annual species, of which 41 were native and six were exotic. Exotic species composed from 64 to 91% of total biomass. We describe a bilateral process of recovery: from the road verge to the outward edge of the corridor and from undisturbed habitat into the corridor. Native annual plants significantly increased in richness from road verge to undisturbed vegetation, but not in density, biomass, or cover. In contrast, exotic annual plants increased in density, biomass, cover and richness with increasing distance from the road verge. The species of colonizing shrubs and type of canopy cover affected density, biomass, and richness of annuals. Species composition of native annuals differed significantly by distance, suggesting secondary succession. In general, native annuals were closer to achieving recovery on the 40-m plots than at the road verge. Recovery estimates were in centuries and dependent on location, canopy type, and whether considering all annuals or natives only.

  14. Risk-informed assessment of regulatory and design requirements for future nuclear power plants. Annual report

    International Nuclear Information System (INIS)

    OAK B188 Risk-informed assessment of regulatory and design requirements for future nuclear power plants. Annual report. The overall goal of this research project is to support innovation in new nuclear power plant designs. This project is examining the implications, for future reactors and future safety regulation, of utilizing a new risk-informed regulatory system as a replacement for the current system. This innovation will be made possible through development of a scientific, highly risk-formed approach for the design and regulation of nuclear power plants. This approach will include the development and/or confirmation of corresponding regulatory requirements and industry standards. The major impediment to long term competitiveness of new nuclear plants in the U.S. is the capital cost component--which may need to be reduced on the order of 35% to 40% for Advanced Light Water Reactors (ALWRS) such as System 80+ and Advanced Boiling Water Reactor (ABWR). The required cost reduction for an ALWR such as AP600 or AP1000 would be expected to be less. Such reductions in capital cost will require a fundamental reevaluation of the industry standards and regulatory bases under which nuclear plants are designed and licensed. Fortunately, there is now an increasing awareness that many of the existing regulatory requirements and industry standards are not significantly contributing to safety and reliability and, therefore, are unnecessarily adding to nuclear plant costs. Not only does this degrade the economic competitiveness of nuclear energy, it results in unnecessary costs to the American electricity consumer. While addressing these concerns, this research project will be coordinated with current efforts of industry and NRC to develop risk-informed, performance-based regulations that affect the operation of the existing nuclear plants; however, this project will go further by focusing on the design of new plants

    Full Text Available The study aimed to evaluate the uptake of trace metals by the tissues of some plants which grow inside, or in the peripheries of, pools of water contaminated by waste water from neighboring industrial complexes in Khartoum City. It also aimed to verify the possibility of making use of this phenomenon in combating metal pollution in water and wastewater catchments. The flame atomic absorption spectrophotometry (FAAS was used to find the concentration of the subject metals in waste water and algal biomass of the phyla Chlorophyta, Cyanophyta, and Bacillariophyta; and in newly grown leaves of Calotropis procera in addition to their stems and roots. The physical parameters studied were pH and electrical conductivity (EC of waste water. The metals studied in waste water, algal biomass and C. procera were Fe, Zn, Cd, Pb, Cu, Ni, and Cr. The study covered during summer and autumn 6 sites in Khartoum city industrial complexes. Samples were collected, and analyzed for TMs concentration levels. The algal biomass was found to be more efficient for TMs uptake and accumulation than the three parts of C. procera. Among the parts of C. procera, the root was more efficient for TMs uptake than the leaf, while the stem was the least efficient.

    In 1994, public hearings were held in Quebec city concerning a 120 megawatt (MW) gas cogeneration project that was to be coupled with an already existing pulp and paper mill in the downtown area. Cogeneration plants are often described as highly beneficial from the point of view of local environment. It is well known that the burning of natural gas emits far less sulfur dioxide (SO{sub 2}) and particulate matters (PM) than the combustion of oil or coal. The proposed plant would use high pressure vapour from a nearby incinerator plant and natural gas to produce low pressure vapor for the paper mill industry as well as electricity. The cogeneration plant would allow the paper mill to stop burning heavy oil. By using natural gas instead of heavy oil, the new cogeneration-paper mill complex (CPC) is expected to reinforce the recent trend and willingness towards improving downtown air quality. On the other hand, the CPC would emit more CO{sub 2}, due to the production of additional electricity. According to the Rio de Janeiro Agreement ratified in 1988, Canada is committed to stabilize its greenhouse gas emissions by the year 2000. Nevertheless, the cogeneration file is a new option considered by the Quebec Provincial Governement in its last energy triennal plan. However, it must be specified that the Province of Quebec contributes to less than 15 % of the total Canadian CO{sub 2} production although it represents more than 25 % of its population. Furthermore the maximum production of electricity by this file has been set to 250 MW. It is a very small fraction of the total production of electricity in Quebec, which is 200 TW

  2. The Legacy of Past Tree Planting Decisions for a City Confronting Emerald Ash Borer (Agrilus planipennis Invasion

    Full Text Available Management decisions grounded in ecological understanding are essential to the maintenance of a healthy urban forest. Decisions about where and what tree species to plant have both short and long-term consequences for the future function and resilience of city trees. Through the construction of a theoretical damage index, this study examines the legacy effects of a street tree planting program in a densely populated North American city confronting an invasion of emerald ash borer (Agrilus planipennis. An investigation of spatial autocorrelation for locations of high damage potential across the City of Toronto, Canada was then conducted using Getis-Ord Gi*. Significant spatial clustering of high damage index values affirmed that past urban tree planting practices placing little emphasis on species diversity have created time-lagged consequences of enhanced vulnerability of trees to insect pests. Such consequences are observed at the geographically local scale, but can easily cascade to become multi-scalar in their spatial extent. The theoretical damage potential index developed in this study provides a framework for contextualizing historical urban tree planting decisions where analysis of damage index values for Toronto reinforces the importance of urban forest management that prioritizes proactive tree planting strategies that consider species diversity in the context of planting location.

  3. Naturally occurring arsenic in the groundwater at the Kansas City Plant

    This report describes an investigation concerning the presence of arsenic in concentrations exceeding 0.4 mg/L in the groundwater under the Department of Energy's Kansas City Plant (KCP). The study consisted of four distinct phases: a thorough review of the technical literature, a historical survey of arsenic use at the facility, a laboratory study of existing techniques for determining arsenic speciation, and a field program including water, soil, and sediment sampling. The historical survey and literature review demonstrated that plant activities had not released significant quantities of arsenic to the environment but that similar occurrences of arsenic in alluvial groundwater are widespread in the midwestern United States. Laboratory studies showed that a chromatographic separation technique was necessary to accurately determine arsenic speciation for the KCP groundwater samples. Field studies revealed that naturally occurring reducing conditions prevalent in the subsurface are responsible for dissolving arsenic previously sorbed by iron oxides. Indeed, the data demonstrated that the bulk arsenic concentration of site subsoils and sediments is {approximately}7 mg/kg, whereas the arsenic content of iron oxide subsamples is as high as 84 mg/kg. Literature showed that similar concentrations of arsenic in sediments occur naturally and are capable of producing the levels of arsenic found in groundwater monitoring wells at the KCP. The study concludes, therefore, that the arsenic present in the KCP groundwater is the result of natural phenomena. 44 refs., 8 figs., 14 tabs.

  4. SEASONALITY OF ANNUAL PLANT ESTABLISHMENT INFLUENCES THE INTERACTIONBETWEEN THE NON-NATIVE ANNUAL GRASS BROMUS MADRITENSIS SSP. RUBENS AND MOJAVE DESERT PERENNIALS

    Competition between native and non-native species can change the composition and structure of plant communities, but in deserts the timing of non-native plant establishment can modulate their impacts to native species. In a field experiment, we varied densities of the non-native annual grass Bromus madritensis ssp. rubens around individuals of three native perennials--Larrea iridentata, Achnatherum hymenoides, and Pleuraphis rigida--in either winter or spring. Additional plots were prepared for the Same perennial species and seasons, but with a mixture of native annual species. Relative growth rates of perennial shoots (RGRs) declined with increasing Bromus biomass when Bromus that was established in winter had 2-3 mo of growth and high water use before perennial growth began. However, this high water use did not significantly reduce water potentials for the perennials, suggesting Bromus that established earlier depleted other soil resources, such as N, otherwise used by perennial plants. Spring-established Bromus had low biomass even at higher densities and did not effectively reduce RGRs, resulting in an overall lower impact to perennials than when Bromus was established in winter. Similarly, growth and reproduction of perennials with mixed annuals as neighbors did not differ from those with Bromus neighbors of equivalent biomass, but densities of these annuals did not support the high biomass necessary to reduce perennial growth. Thus, impacts of native Mojave Desert annuals to perennials are expected to be lower than those of Bromus because seed dormancy and narrow requirements for seedling survivorship produce densities and biomass lower than those achieved by Bromus. In comparing the effects of Bromus among perennial species, the impact of increased Bromus biomass on RGR was lower for Larrea than for the two perennial grasses, probably because Lurrea maintains low growth rates throughout the year, even after Bromus has completed its life cycle. This contrasts

    Investigation was carried out to find whether enhanced ultraviolet radiation influences the Malva parviflora L., Plantago major L., Rumex vesicarius L. and Sismbrium erysimoids Desf. of some annual desert plants. The seeds were grown in plastic pots equally filled with a pre-sieved normal sandy soil for 1 month. The planted pots from each species were randomly divided into equal groups (three groups). Plants of the first group exposed to white-light tubes (400-700 nm) 60 w and UV (365 nm) 8 w tubes. The second group was exposed to white-light tubes (400-700 nm) 60 w and UV (302 nm) 8 w tubes. The third group was exposed to white-light tubes (400-700 nm) 60 w and UV (254 nm) 8 w tubes, respectively, for six days. The results indicated that the chlorophyll contents were affected by enhanced UV radiation. The chlorophyll a, b, and total contents were decreased compared with the control values and reduced with the enhanced UV radiation, but the carotenoid was increased compared with the control and also reduced with the enhanced UV radiation. So, the contents of chlorophylls varied considerably. M. parviflora showed the highest constitutive levels of accumulated chlorophyll a, b, and total chlorophyll (0.463, 0.307 and 0.774 mg g(-1) f w) among the investigated plant species. P. major showed the lowest constitutive levels of the chloroplast pigments, 0.0036, 0.0038 and 0.0075 mg g(-1) f w for chlorophyll a, b, and total chlorophyll at UV-365 nm, respectively. The protein content was decreased significantly in both root and shoot systems compared with the control values but, it was increased with increasing wave lengths of UV-radiation of all tested plants. R. vesicarius showed the highest protein contents among the investigated plants; its content was 3.8 mg g(-1) f w at UV-365 nm in shoot system. On the other hand, decreasing ultraviolet wave length induced a highly significant increase in the level of proline in both root and shoot of all

  7. CO2 and temperature effects on leaf area production in two annual plant species

    International Nuclear Information System (INIS)

    The authors studied leaf area production in two annual plant species, Abutilon theophrasti and Amaranthus retroflexus, under three day/night temperature regimes and two concentrations of carbon dioxide. The production of whole-plant leaf area during the first 30 d of growth was analyzed in terms of the leaf initiation rate, leaf expansion, individual leaf area, and, in Amaranthus, production of branch leaves. Temperature and CO2 influenced leaf area production through effects on the rate of development, determined by the production of nodes on the main stem, and through shifts in the relationship between whole-plant leaf area and the number of main stem nodes. In Abutilon, leaf initiation rate was highest at 38 degree, but area of individual leaves was greatest at 28 degree. Total leaf area was greatly reduced at 18 degree due to slow leaf initiation rates. Elevated CO2 concentration increased leaf initiation rate at 28 degree, resulting in an increase in whole-part leaf area. In Amaranthus, leaf initiation rate increased with temperature, and was increased by elevated CO2 at 28 degree. Individual leaf area was greatest at 28 degree, and was increased by elevated CO2 at 28 degree but decreased at 38 degree. Branch leaf area displayed a similar response to CO2, butt was greater at 38 degree. Overall, wholeplant leaf area was slightly increased at 38 degree relative to 28 degree, and elevated CO2 levels resulted in increased leaf area at 28 degree but decreased leaf area at 38 degree

    Investigations and discussions have been given on energy saving possibilities at two medium-sized heat and power supplying plants in the city of Dailian in China. The project will improve the operation methods of the heat and power plants so that the energy cost can be minimized, and attempt to improve the boiler heat efficiency and save the energy by means of heat recovery and utilization. The draft modification plan for energy conservation has planned operation optimization for energy conservation, control of boiler operation under variable pressure, modification of the external boiler heat converter, use of inverters for the large capacity motors for boilers, and recovery of heat from the boiler blow-down water. In the analysis, models were structured from the operation data, and the effects of applying the energy saving measures were derived from simulation. As a result, the energy saving effect was found to be about 13,000 tons at the Chunhai plant and about 7,000 tons at the Pulandian plant annually (converted to oil). The reduction in greenhouse gas emission was found to be about 40,000 tons at the Chunhai plant and about 20,000 tons at the Pulandian plant annually. The number of years for investment payback is about 4.1 years at the Chunhai plant, and about 4.9 years at the Pulandian plant, wherein good profitability can be estimated. (NEDO)

  11. Kansas City plant ultraviolet/ozone/hydrogen peroxide groundwater treatment system overview

    International Nuclear Information System (INIS)

    The Kansas City Plant (KCP) has committed to the utilization of a groundwater treatment system, for removal of volatile organic compounds (VOCs), that discharges a minimal amount of pollutants to the environment. An advanced oxidation process (AOP) system utilizing ozone, ultraviolet radiation, and hydrogen peroxide serves in this capacity. Packed tower aeration and activated carbon filtration are listed as best available technologies (BATs) by the Environmental Protection Agency (EPA) for the removal of VOCs in water. The disadvantage to these BATs is that they transfer the VOCs from the water medium to the air or carbon media respectively. Operation of the system began in May 1988 at a flow rate of 22.7 liters per minute (lpm) (6 gallons per minute (gpm)). An additional 102.2 lpm (27 gpm) of flow were added in October 1990. Various efforts to optimize and track the treatment unites efficiency have been carried out. A maximum influent reading of 26,590 parts per billion (ppb) of total VOCs has been recorded. Following the addition of flows, removal efficiency has averaged approximately 95%. Both air and water effluents are factored into this calculation. (author)

    The Schuylkill Metals facility in Plant City Florida (SMPCI) operated as a battery recycling facility for approximately 13 years. During its operation, the facility disposed of battery components in surrounding wetland areas. In March of 1991 the U.S. EPA and SMPCI entered into a Consent Decree for the remediation of the SMPCI site using stabilization/solidification and on-site disposal. In November of 1994, ENTACT began remediation at the facility and to date has successfully stabilized/solidified over 228,000 tons of lead impacted battery components and lead impacted material. The ENTACT process reduces the size of the material to be treated to ensure that complete mixing of the phosphate/cement additive is achieved thereby promoting the chemical reactions of stabilization and solidification. ENTACT has met the following performance criteria for treated material at the SMPCI site: (1) Hydraulic Conductivity less than 1x10{sup -6} cm/s, (2) Unconfined Compressive Strength greater than 50 psi, (3) Lead, Cadmium, Arsenic, Chromium TCLP Leachability below hazardous levels.

  13. Causes and consequences of complex population dynamics in an annual plant, Cardamine pensylvanica

    Crone, E.E.

    1995-11-08

    The relative importance of density-dependent and density-independent factors in determining the population dynamics of plants has been widely debated with little resolution. In this thesis, the author explores the effects of density-dependent population regulation on population dynamics in Cardamine pensylvanica, an annual plant. In the first chapter, she shows that experimental populations of C. pensylvanica cycled from high to low density in controlled constant-environment conditions. These cycles could not be explained by external environmental changes or simple models of direct density dependence (N{sub t+1} = f[N{sub t}]), but they could be explained by delayed density dependence (N{sub t+1} = f[N{sub t}, N{sub t+1}]). In the second chapter, she shows that the difference in the stability properties of population growth models with and without delayed density dependence is due to the presence of Hopf as well as slip bifurcations from stable to chaotic population dynamics. She also measures delayed density dependence due to effects of parental density on offspring quality in C. pensylvanica and shows that this is large enough to be the cause of the population dynamics observed in C. pensylvanica. In the third chapter, the author extends her analyses of density-dependent population growth models to include interactions between competing species. In the final chapter, she compares the effects of fixed spatial environmental variation and variation in population size on the evolutionary response of C. pensylvanica populations.

    The fluorine contents in snow melt water find in the impact areas of aluminum production plant and coal and gas-fired power plant are compared. In melt water, soluble fluoride is found in the form of fluoride ion, the content of which was determined by the potentiometric method using ion-selective electrode. According to the measurements of 2013-2014, fluoride content in melt water ranges 10.6-15.4 mg/dm3 at the distance 1-3 km from the borders of Krasnoyarsk aluminum plant with the mean value 13.1 mg/dm3. Four-year monitoring from 2012 to 2015 in the impact area of Tomsk coal and gas-fired power plant showed that fluoride content in melt water in vicinity of the thermal power plant is significantly lower than in the samples from the impact area of the aluminum plant. But higher content of fluoride ion (0.2 - 0.3 mg/dm3) in snow samples in vicinity of coal and gas-fired power plant was revealed in winter of 2015. Intake of soluble fluoride is mostly explained by dust-aerosol emissions of study plants and deposition of fluorine compounds from air.

  17. Biological recipient control at the Ringhals nuclear power plant. Annual report for 2011

    International Nuclear Information System (INIS)

    The cooling system of the Ringhals nuclear power plant affects the fish community in two steps. In the first step, seawater is used to cool the system in the nuclear power plant. Fish eggs, larvae and small juveniles are carried by the incoming water and are exposed to risk of damage or mortality. In the second step the heated water is released back into the sea, where the fish is affected by the increase in temperature. Reactor 1 and reactor 3 at Ringhals nuclear power plant produced electricity during the major part of the year 2011, with exceptions for the annual audits, and shorter stops in production. Reactor 2 only operated between January and April, due to a fire which led to a shutdown and a thorough remediation work during the rest of the year. Reactor 4 was producing electricity from January to June, but was later shutdown due to a prolonged annual audit until November. Fish eggs and fish larvae are sampled in the incoming cooling water using a modified Bongo net to monitor losses of eggs and larvae in the nuclear power plant. The abundance of shorthorn sculpin larvae (Myoxocephalus scorpius) has decreased since the sampling period started, although it is still the most abundant larvae. Also the abundance of rock gunnel larvae (Pholis gunnellus) has decreased over the years. To sample juvenile fish a modified Isaacs-Kidd midwater-trawl is used. This sampling is mainly focused on glass eels (Anguilla anguilla). The abundance of glass eels have declined strongly since the beginning of the 1980's, but a minor increase was observed in 2011. The decline of the glass eel abundance is most probably due to a general decrease in recruitment and not to a local effect caused by the nuclear power plant. The effects of the heated water released into the sea are monitored by fykenet surveys in the recipient as well as in a reference area. These two areas are monitored in two seasons to compare differences between the two areas in naturally cold and warm water of the

    International Nuclear Information System (INIS)

    The use of nuclear power plants for electricity supply is presently considered as an important factor to be considered in any energy matrix to ensure the diversification and availability criteria. Currently several countries resumed or started programs for the construction of nuclear power plants of new projects, with extremely improved security levels. Additionally, events and accidents in nuclear power plants have contributed substantially to the occurrence of design modifications and/or update the regulatory requirements to further enhance operational safety of these plants. Nowadays, one of the regulatory requirements necessary for the selection of a site for construction and operation of nuclear installations is the public hearing and discussion. The city of Angra dos Reis has two nuclear power plants in operation and a third one under construction. There are also, plans for the construction of more nuclear power plants in the country, to meet the growing demand for electricity. The first nuclear power plant in Brazil went into operation in 1983 and the second in 2000. The selection of the site for construction of these plants was due to political, economic and strategic factors, present in Brazil, in the decade of 70. The licensing process in de 70's decade did not involve an extensive participation of the society as a whole and of the local population, such as the occurrence of public hearings and the wide possibility for discussion and debate about the acceptance of the location of the plant. In the initial years of operation of the Angra 1 nuclear power plant, the level of knowledge of the local population was practically null, occurring mainly in local clarifications, made through seminars and lectures on special occasions, such as at the time of the annual exercises of the external emergency plan, specific information Programs or technical visits of educational institutions and the Government to Angra dos Reis Nuclear power plant.

  5. Soil moisture and fungi affect seed survival in California grassland annual plants.

    Directory of Open Access Journals (Sweden)

    Full Text Available Survival of seeds in the seed bank is important for the population dynamics of many plant species, yet the environmental factors that control seed survival at a landscape level remain poorly understood. These factors may include soil moisture, vegetation cover, soil type, and soil pathogens. Because many soil fungi respond to moisture and host species, fungi may mediate environmental drivers of seed survival. Here, I measure patterns of seed survival in California annual grassland plants across 15 species in three experiments. First, I surveyed seed survival for eight species at 18 grasslands and coastal sage scrub sites ranging across coastal and inland Santa Barbara County, California. Species differed in seed survival, and soil moisture and geographic location had the strongest influence on survival. Grasslands had higher survival than coastal sage scrub sites for some species. Second, I used a fungicide addition and exotic grass thatch removal experiment in the field to tease apart the relative impact of fungi, thatch, and their interaction in an invaded grassland. Seed survival was lower in the winter (wet season than in the summer (dry season, but fungicide improved winter survival. Seed survival varied between species but did not depend on thatch. Third, I manipulated water and fungicide in the laboratory to directly examine the relationship between water, fungi, and survival. Seed survival declined from dry to single watered to continuously watered treatments. Fungicide slightly improved seed survival when seeds were watered once but not continually. Together, these experiments demonstrate an important role of soil moisture, potentially mediated by fungal pathogens, in driving seed survival.

  7. Assessment of annual effective dose from 238U and 226Ra due to consumption of foodstuffs by inhabitants of Tehran city (IR)

    International Nuclear Information System (INIS)

    The concentrations of 238U and 226Ra were determined in different foodstuffs purchased from markets in Tehran. Determinations of the radionuclides have been carried out using alpha spectrometry technique, on samples of egg, lentil, potato, rice, soya, spinach, tea and wheat. Average concentrations of natural radionuclides and foodstuff consumption rate were used to assess annual intake and based on intake values, the annual effective ingestion dose has been estimated for Tehran city residents. The measurement results show that soya has the maximum concentration of 238U equal to 15.6 ± 2.6 mBq kg-1 and tea has the maximum concentration of 226Ra equal to 1153.3 ± 265.3 mBq kg-1. Besides, the maximum annual effective dose from 238U and 226Ra were assessed to be 2.88 x 10-2 ±7.20 x 10-3 and 2.15 ± 0.54 μSv, respectively, from wheat samples. (authors)

    The combustion of coal usually leads to many different kinds of pollution around coke-making factories. Among these pollutions, the heavy metal contamination in the soil and plants is one of the major concerns by people living around. Heavy metals are highly attracted to the biological tissue, and can stay in bodies of organisms for long period of time, causing a lot of hazardous diseases to human beings, animal and plants. In the developing regions of China, developing of industries has been based on the sacrifices of environments and human health. In order to evaluate the danger of heavy metal contamination from a coke factory to citizens of close inhabitants, a survey on soil and plants was conducted in the region around a coke-making factory in Jiyuan city, which is a major electricity supplying city for the Henan Province in China. In this study, 8 surface soil samples and 11 plant samples were collected from 8 different places around the coke-making factory in Jiyuan city. The collected samples are then treated in the laboratory, and 8 types of heavy metals, which include arsenic, cadmium, chromium, cobalt, copper, lead, nickel and zinc, are analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). The concentration data of heavy metals that collected from the analysis are then used to evaluate their toxicity towards living organisms and ecology by applying several biological effect standards, such as effect-range low (ERL), effect-range median (ERM) and several maximum allowances standards of heavy metal concentrations in soils and plants that established by different countries. Moreover, the relationship between the distance from the factory and the concentration of heavy metals in soils and plants are also evaluated in order to find out the contamination ranges of those heavy metals from the source. The result shows that the concentration of these 8 types of heavy metals in the

  14. A plant taxonomic survey of the Uranium City region, Lake Athabasca north shore, emphasizing the naturally colonizing plants on uranium mine and mill wastes and other human-disturbed sites

    International Nuclear Information System (INIS)

    A goal of this study was to acquire more complete baseline data on the existing flora of the Uranium City region, both in natural and human-disturbed sites. Emphasis was given to determining which plant species were naturally revegetating various abandoned uranium mine and mill waste disposal areas, other human-disturbed sites, and ecologically analogous sites. Another goal was to document the occurrence and distribution in the study region of rare and possibly endangered species. A further objective was to suggest regionally-occurring species with potential value for revegetating uranium mine and mill waste sites. Field investigations were carried out in the Uranium City region during August, 1981. During this time 1412 plant collections were made; a total of 366 plant species - trees, shrubs, forbs, graminoids, lichens, and bryophytes were recorded. The report includes an annotated checklist of plant species of the Uranium City region and a reference index of plant taxa indicating species that have high revegetation potential

    The article shows the results of dust pollution level of air in the vicinity of coal-fired power plant of Omsk city on the base of study snow cover pollution. The samples were collected west-, east- and northeastwards at a distance of 0,75-6 km from the chimney for range-finding of dust emission transfer. The research findings have shown the dust load changes from 53 till 343 mg•(m2·day)-1 in the vicinity of power plant. The ultimate dust load was detected at a distance of 3-3,5 km. On the basis of asymptotics of equation solution for impurity transfer, we have made numerical analysis of dust load rate. With the usage of ground-based facilities and satellites we have determined the wind shifts in the atmospheric boundary layer have a significant impact on the field forming of long-term dustfall.

  16. Proceedings of the 29. Annual ESNA/UIR Meeting: Soil-Plant Relationships

    International Nuclear Information System (INIS)

    The annual meeting were presented in 42 papers by scientists originating from 15 countries. The first part of the sessions dealt with recent developments in terrestrial radioecology, addressing both agricultural and semi-natural environments (12 oral presentations, 2 posters). Mitchell (U.K.) reported on the present status of the flux database of UIR, which, due to its 17000 entries provides an excellent basis for applying or testing new model approaches. One paper was presented on the upward movement of mobile (Na, CI) and less mobile (Cs) radionuclides in soil columns (Wadey/UK). Skarlou/Greece and Goncharova/Byelorussia highlighted important impact factors on soil-plant transfer of Cs and Sr as soil pH and ageing of contaminants/hot particles. Two presentations (Kirchner/Germany, Konopleva/Russia) focused on successful soil scientific approaches to describe plant uptake of Cs and Sr taking into account ion competition in soil. Klemt/Germany presented an interesting model to estimate Cs-transfer to roe leer and highlighted the importance of mushroom in this respect. The important role of fungi for Cs-dynamics in forest soil was confirmed by the data of Nikolova/Bulgaria. Spiridonov/Russia presented a radioecological model describing Cs-dynamics in forest ecosystems. The forestland/fortree model is parameterized for both deciduous and coniferous forests. A set of three papers (Tkachenko/Ukraine, Goncharova/Byelorussia, Oncsik/Hungary) focused on countermeasures. lt became quite evident that the effect of applications of macro- and micronutrients, clay minerals and zeolithes on radionuclide soil-plant transfer is highly site specific and needs consideration of soil properties. Two papers described the long-term impact of radionuclide contamination on the collective dose of the population (Kravets/Ukraine, Goncharova/Byelorussia). The contribution in the field of soil and plant sciences covered a broad range of topics. Influencing soil physical properties by

    Science.gov (United States)

    Peterseim, J. H.; Viscuso, L.; Hellwig, U.; McIntyre, P.

    2016-05-01

    This paper analyses the potential to optimize high temperature fluid back-up systems for concentrating solar power (CSP) plants by investigating the cost impact of component capacity and the impact of using multiple fuels on annual generation. Until now back-up heaters have been limited to 20MWth capacity but larger units have been realised in other industries. Installing larger units yields economy-of-scale benefits through improved manufacturing, optimised transport, and minimized on-site installation work. Halving the number of back-up boilers can yield cost reduction of 23% while minimizing plant complexity and on-site construction risk. However, to achieve these benefits it is important to adapt the back-up heaters to the plant's requirements (load change, capacity, minimum load, etc.) and design for manufacture, transport and assembly. Despite the fact that biomass availability is decreasing with increasing direct normal irradiance (DNI), some biomass is available in areas suitable for CSP plants. The use of these biomass resources is beneficial to maximise annual renewable energy generation, substitute natural gas, and use locally/seasonally available biomass resources that may not be used otherwise. Even small biomass quantities of only 50,000 t/a can increase the capacity factor of a 50MWe parabolic trough plant with 7h thermal energy storage from 40 to 49%. This is a valuable increase and such a concept is suitable for new plants and retrofit applications. However, similar to the capacity optimisation of back-up heaters, various design criteria have to be considered to ensure a successful project.

    Impatiens glandulifera (Common English Name - Himalayan Balsam) is a non native annual and highly invasive plant that was introduced into parts of Europe from the Himalaya during the nineteenth century as a colourful adornment to parks and gardens. This Plant colonises areas along the river banks, preferably wet, depositional sites, and displaces natural vegetation. The plant is killed by cold weather. The leaves area of riverbank previously occupied by the plant extremely vulnerable to soil erosion until new plant germinates in the following spring. Research work undertaken in the northwest Switzerland and the soutwestern United Kingdom established s link between accelerated soil erosion caused by Impatiens glandulifera and its detrimental impact on native biodiversity of riparian zone of river catchment area. This study focueses on the potential impact of such erosion on sediment quality. A priory reasoning suggests that the preference of Impatiens glandulifera on young depsotional sites near watercourses affects sediment quality. In this study, the results of a soil quality analysis along Impatiens glandulifera-contaminated river banks is presented. Soil physical and chemical properties are compared to non-affected sites to assess the potential impact of preferential erosion on water quality. In addtiion, soil surface profile (SSP) measuring based on by erosion pins, a micro profile bridge and a digital calliper at different selected locations along the riparian zone of river catchment area is used to determine erosion rates and determine sediment transfer from the riparian zone into the rivers.

    The principal objective is to evaluate, at proof-of-concept scale, the potential of intensive aquaculture operations using power plant thermal discharges to enhance productivity. The field experiments involve the rearing of rainbow trout (Salmo gairdneri), channel catfish (Ictalurus punctatus) and American eel (Anguilla rostrata) for successive periods (semi-annual) in accordance with the temperature of the thermal effluents. Striped bass (Morone saxatilis) and the freshwater shrimp (Macrobrachium rosenbergii) are also being tested in smaller, laboratory size culture systems. The above mentioned species were selected because of their economic importance. They will be evaluated for food quality and marketability with the cooperation of potential commercial users. Aquaculture facilities were constructed at a steam electric generating plant for studies determining use for waste heat released into condenser cooling water. Growth rates, food conversion ratios, disease problems and mortality rates are being studied in the project.

    Full Text Available The sewage sludge from wastewater treatment plant of Iasi, a city with 300,000 inhabitants, for domestic and industrial origin, was stored in a mud pond arranged on an area of 18,920 m2. Chemical analyzes of the sludge showed that, of all the chemical elements determined, only Zn is found at pollutant level (5739 mg∙kg-1, i.e. almost 30 times more than the maximum allowable limit for Zn in soil and 45 times more than the Zn content of the soil on which the mud pond has been set. Over time, the content of Zn in the mud pond, but also from soil to which it has been placed, has become upper the normal content of the surrounding soil up to a depth of 260 cm. On the other hand, the vegetation installed on sewage sludge in the process of mineralization, composed predominantly of Phragmites, Rumex, Chenopodium, and Aster species had accumulated in roots, stems and leaves Zn quantities equivalent to 1463 mg Kg-1, 3988 mg Kg-1, 1463 mg Kg-1, respectively, 1120 mg∙Kg-1. The plants in question represents the natural means of phytoremediation, and sewage sludge as such may constitute a fertilizer material for soils in the area, on which Zn deficiency in maize has been recorded. In addition, the ash resulted from the incineration of plants loaded with zinc may constitute, in its turn, a good material for fertilizing of the soils that are deficient in zinc.

  8. Psychosocial work strain of maintenance personnel during annual outage and normal operation in a nuclear power plant

    International Nuclear Information System (INIS)

    This paper reports on a study which evaluates psychosocial work demands during the annual outage for a maintenance work group in a nuclear power plant. The study is based on a stress paradigm and it has been asserted that increased work strain would have a negative effect on performance. Nineteen workers, aged 20-55 years, participated in the study. The subjects filled out a questionnaire comparing work strain during annual outage and normal operation. During the outage period a 3-shift 24-hour work schedule, including nightwork, was used (working hours during normal operation was 7-16). Increased demands on concentration and vigilance, increased time pressure and strain on social relations within the group were found to characterize work during annual outage. Interestingly, for specific work tasks an association was found between the risk of making errors and high psychological workload. Increased work strain, shiftwork including nightwork and reduced social support are important psychosocial risk factors that might contribute to human error during the outage period

    Climate change plays an important role in the transition of ecosystems. Stratigraphic investigations have suggested that the Asian interior experienced frequent transitions between grassland and desert ecosystems as a consequence of global climate change. Using maternally and bi-parentally inherited markers, we investigated the population dynamics of Agriophyllum squarrosum (Chenopodiaceae), an annual pioneer plant endemic to mobile sand dunes. Phylogeographic analysis revealed that A. squarrosum could originate from Gurbantunggut desert since ~1.6 Ma, and subsequently underwent three waves of colonisation into other deserts and sandy lands corresponding to several glaciations. The rapid population expansion and distribution range shifts of A. squarrosum from monsoonal climate zones suggested that the development of the monsoonal climate significantly enhanced the population growth and gene flow of A. squarrosum. These data also suggested that desertification of the fragile grassland ecosystems in the Qinghai-Tibetan Plateau was more ancient than previously suggested and will be aggravated under global warming in the future. This study provides new molecular phylogeographic insights into how pioneer annual plant species in desert ecosystems respond to global climate change, and facilitates evaluation of the ecological potential and genetic resources of future crops for non-arable dry lands to mitigate climate change.

    Severe eutrophication of surface water has been a major problem of increasing environmental concern worldwide. In the present study, economic plant annual ryegrass (Lolium multiflorum) was grown in floating mats as an economic plant-based treatment system to evaluate its potential after ion implantation for removing nutrients in simulated eutrophic water. The specific weight growth rate of L. multiflorum with ion implantation was significantly greater than that of the control, and the peroxidase, nitrate reductase, and acid phosphatase activities of the irradiated L. multiflorum were found to be greater than those plants without ion implantation. Higher total nitrogen (TN) and total phosphorus (TP) removal efficiencies were obtained for the L. multiflorum irradiated with 25 keV 5.2 × 10(16) N(+) ions/cm(2) and 30 keV 4.16 × 10(16) N(+) ions/cm(2), respectively (p phosphorus contents in the plant biomass with ion implantation were also greater than those in the control and were positively correlated with TN and TP supplied. L. multiflorum itself was directly responsible for 39-49 and 47-58 % of the overall N and P removal in the experiment, respectively. The research results suggested that ion implantation could become a promising approach for increasing phytoremediation efficiency of nutrients from eutrophic water by L. multiflorum.

  15. Determination of cesium-137 soil-to-plant concentration ratios for vegetables in Goiania City, Brazil

    International Nuclear Information System (INIS)

    The radiological accident that occurred in Goiania City, Brazil, in September 1987, led to the spreading of 137Cs in the urban area. Even after the decontamination procedure, there was a reminiscence of 137Cs activity in the soil of residential gardens. This activity was enough to conduct preliminary experiments for determination of soil to vegetable concentration ratios. Experiments were conducted for carrots, lettuce and radishes. Two types of experimental patterns were used to determine the concentration ratios: lysimeters cultivation under greenhouse condition and soil cultivation in open field plot. The concentration ratios measured for cultivation under greenhouse and field plot conditions are considerably higher than those mentioned in the International Union of Radioecologist (IUR) data bank for the same vegetables and cultivation condition.

    The presence of the biogenic hydrocarbons in an NO_x-containing atmosphere can enhance ozone generation and the impact of volatile organic compounds (VOCs) emitted from vegetation on atmospheric chemistry has been investigated. No study of VOC emission rates from plant species has been carried out in São Paulo City, Brazil, prior to this work. This study is part of a three-years project on biogenic volatile organic compounds emissions from species of plants found in the vegetation of the São Paulo metropolitan area. Typical plants (Alchornea sidifolia, Cupania oblongifolia, Cecropia pachystachia, Casearia sylvestris, Machaerium villosum, Croton floribundus, Myrcia rostrata, Solanum erianthum and Ficus insípida) were selected and identical species were studied in urban, sub-urban and forest regions. Biogenic hydrocarbons were determined placing branches of plants in enclosures and measuring the accumulation of emitted compounds in an all-Teflon chamber, the cuvette system. Measuring ambient VOC concentration adsorptive preconcentration, followed by GC-MS after thermal desorption of the sample, was employed to determine components heavier than C_5. Collection of carbonyl compounds on 2, 4-dinitrophenylhydrazine coated particles followed by HPLC-UV was used to analyze low molecular weight carbonyl compounds. Emissions rates of isoprene, a-pinene, camphene and limonene ranged from 0.01 to 2.16 μg C/h.g and emissions rates of aldehydes (C_1 - C_6), acrolein, methacrolein, 2-butanone and acetone ranged from 0.04 to 4.20 μg C/h.g. Ambient and chamber temperatures, relative humidity, light intensity, O_3 and NO_x were monitored during experiments.

  5. How does altered precipitation and annual grass invasion affect plant N uptake in a native semi-arid shrub community?

    Science.gov (United States)

    Mauritz, M.; Lipson, D.; Cleland, E. E.

    2012-12-01

    Climate change is expected to alter precipitation patterns, which will change the timing and amount of plant resources. Precipitation patterns determine water and nitrogen (N) availability, because water stimulates microbial N turnover and N transport. In order for plants to utilize water and N, they must coincide with the phenology and meet physiological requirements of the plant. As resource supply shifts, differences in species' ability to acquire resources will affect plant community composition. Semiarid ecosystems, such as shrublands in Southern California, are particularly sensitive to shifts in precipitation because they are severely water limited. This study takes advantage of the altered phenology and resource demands presented by invasive annual grasses in a native semiarid shrubland. The goal is to understand how altered precipitation patterns affect plant N uptake. Rainfall levels were manipulated to 50% and 150% of ambient levels. It is expected that higher rainfall levels promote annual grass invasion because grasses have higher water and N requirements and begin to grow earlier in the season than shrubs. A 15N tracer was added with the first rain event and plant samples were collected regularly to track the movement of N into the plants. Net soil N accumulation was determined using resin bags. Invasive grasses altered the timing and amount of N uptake but amount of rainfall had less effect on N distribution. 15N was detected sooner and at higher level in grasses than shrubs. 24hours after the first rain event 15N was detectable in grasses, 15N accumulated rapidly and peaked 2 months earlier than shrubs. Shrub 15N levels remained at pre-rain event levels for the first 2 months and began to increase at the beginning of spring, peak mid-spring and decline as the shrubs entered summer dormancy. One year later 15N levels in annual grass litter remained high, while 15N levels in shrubs returned to initial background levels as a result of resorption. 15N

    2007-09-01

    The Very High Temperature Gas-Cooled Reactor (VHTR) coupled to the High Temperature Steam Electrolysis (HTSE) process is one of two reference integrated systems being investigated by the U.S. Department of Energy and Idaho National Laboratory for the production of hydrogen. In this concept the VHTR outlet temperature of 900 °C provides thermal energy and high efficiency electricity for the electrolysis of steam in the HTSE process. In the second reference system the Sulfur Iodine (SI) process is coupled to the VHTR to produce hydrogen thermochemically. In the HyPEP project we are investigating and characterizing these two reference systems with respect to production, operability, and safety performance criteria. Under production, plant configuration and working fluids are being studied for their effect on efficiency. Under operability, control strategies are being developed with the goal of maintaining equipment within operating limits while meeting changes in demand. Safety studies are to investigate plant response for equipment failures. Specific objectives in FY07 were (1) to develop HyPEP Beta and verification and validation (V&V) plan, (2) to perform steady state system integration, (3) to perform parametric studies with various working fluids and power conversion unit (PCU) configurations, (4) the study of design options such as pressure, temperature, etc. (5) to develop a control strategy and (6) to perform transient analyses for plant upsets, control strategy, etc for hydrogen plant with PCU. This report describes the progress made in FY07 in each of the above areas. (1) The HyPEP code numeric scheme and Graphic User Interface have been tested and refined since the release of the alpha version a year ago. (2) The optimal size and design condition for the intermediate heat exchanger, one of the most important components for integration of the VHTR and HTSE plants, was estimated.

  9. Chemical characteristics of organic aerosols in Algiers city area: influence of a fat manufacture plant

    Science.gov (United States)

    Yassaa, Noureddine; Meklati, Brahim Youcef; Cecinato, Angelo

    Total concentrations and homologue distributions of organic fraction constituents have been determined in particulate matter emitted from different units of a fat manufacturer (i.e. oils refining and conditioning plants, and production and conditioning units of a soap industry) located in Algiers area, as well as in atmospheric aerosols. In particular n-alkanes, n-alkanoic and n-alkenoic acids, n-alkan-2-ones and polycyclic aromatic hydrocarbons (PAH) were investigated. Organic aerosol contents varied broadly among the plant units, depending upon nature of the manufactured products. The percent composition of all classes of compounds investigated in ambient atmosphere was similar to those observed indoor at industrial plant units. Organic acids, n-alkanoic as well as n-alkenoic, appeared by far the most abundant organic constituents of aerosols, both indoor and outdoor, ranging from 7.7 to 19.8 and from 12.7 to 17.1 μg m -3, respectively. The huge occurrence of acids and n-alkanes in ambient aerosols was consistent with their high levels present in oil and fat materials. Among minor components of aerosols, n-alkan-2-ones and PAH, seemed to be related to thermally induced ageing and direct combustion of raw organic material used for oil and soap production.

  10. Optimal annual operation of the dry cooling system of a concentrated solar energy plant in the south of Spain

    International Nuclear Information System (INIS)

    This work presents the optimization of the operation of a concentrated solar power plant with dry cooling over a year, evaluating the molten salts storage, the power block and the air cooling system as a function of the climate and atmospheric conditions. We locate the plant in the south of Europe, Almería (Spain), due to the high solar irradiation and for comparison purposes with a wet cooling based facility. The optimization of the system is formulated as a multiperiod MINLP (mixed integer non-linear programming problem) that is solved for the optimal production of electricity over a year defining the main operating variables of the thermal cycles and the cooling system. The power produced ranges from 9.5 MW in winter to 25 MW in summer, where 5% of this power is consumed by the air cooling system. The annual production cost of electricity is 0.16 €/kWh and the investment required is 265 M€, both slightly higher than when wet cooling is used, but with negligible water consumption. For the selected location, the wet based technology generates slightly less CO2 than the air cooled facility. - Highlights: • A CSP plant with dry cooling is optimized using mathematical programming. • The facility involves solar field, molten salts, steam and electricity generation and cooling. • Dry cooling is more expensive and requires 5% of the produced energy. • CO2 savings do not recommend dry system. Water scarcity does

  12. Plant rhizosphere effects on metal mobilization and transport. 1998 annual progress report

    Energy Technology Data Exchange (ETDEWEB)

    Fan, T.W.M.

    1998-06-01

    'Information on the mechanism of how plants mobilize, uptake, and metabolize metal ions is very limited. Especially deficient is the understanding of these processes involving pollutant metal ions and interactions among these ions. Based on the current knowledge regarding nutrient ions, it is clear that elucidation of rhizospheric processes such as exudation of organic ligands by plant roots and plant metabolism/adaptation involving these biogenic chelators is critically important. A mechanistic insight into these processes will advance knowledge in microbe-plant host interactions and how metal ions are mobilized, immobilized, and sequestered by these interactions. This, in turn, is essential to applications such as phytobioremediation and microbioremediation of metal ion pollution. Root exudation also serves many other important rhizosphere functions including energy supply for microbial degradation of organic pollutants, structuring of microbial community, and the formation of soil humic materials which are considered to be a major sink for both organic and inorganic pollutants. How root exudates function is critically dependent on the chemical nature of exudate components. Therefore, a comprehensive characterization of all major exudate components, regardless of their chemical class, should facilitate the development and implementation of bioremediation for both organic and inorganic pollutants. Therefore, the objectives of this project are: (1) To obtain a comprehensive composition of major organic components in plant root exudates as a function of different metal ions; (2) To examine plant metabolic response(s) to these metal ion treatments, with emphasis on biosynthetic pathways of organic ligands; and (3) To investigate the effect(s) of soil microbial (e.g. mycorrhizae) association on (1) and (2).'

    In 1980 US electric utilities reported purchasng 594 million tons of coal, 408.5 million barrels of oil and 3568.7 billion ft/sup 3/ of gas. As compared with 1979 purchases, coal rose 6.7%, oil decreased 20.9%, and gas increased for the fourth year in a row. This volume presents tabulated and graphic data on the cost and quality of fossil fuel receipts to US electric utilities plants with a combined capacity of 25 MW or greater. Information is included on fuel origin and destination, fuel types, and sulfur content, plant types, capacity, and flue gas desulfurization method used, and fuel costs. (LCL)

    The current study has examined four cases of a central receiver concentrated solar power plant with thermal energy storage using the DELSOL and SOLERGY computer codes. The current state-of-the-art base case was compared with a theoretical high temperature case which was based on the scaling of some input parameters and the estimation of other parameters based on performance targets from the Department of Energy SunShot Initiative. This comparison was done for both current and high temperature cases in two configurations: a surround field with an external cylindrical receiver and a north field with a single cavity receiver. There is a fairly dramatic difference between the design point and annual average performance, especially in the solar field and receiver subsystems, and also in energy losses due to the thermal energy storage being full to capacity. Additionally, there are relatively small differences (<2%) in annual average efficiencies between the Base and High Temperature cases, despite an increase in thermal to electric conversion efficiency of over 8%. This is due the increased thermal losses at higher temperature and operational losses due to subsystem start-up and shut-down. Thermal energy storage can mitigate some of these losses by utilizing larger thermal energy storage to ensure that the electric power production system does not need to stop and re-start as often, but solar energy is inherently transient. Economic and cost considerations were not considered here, but will have a significant impact on solar thermal electric power production strategy and sizing.

  15. Nuclear waste-form risk assessment for US Defense waste at Savannah River Plant. Annual report FY 1981

    International Nuclear Information System (INIS)

    Savannah River Plant has been supporting the Lawrence Livermore National Laboratory in its present effort to perform risk assessments of alternative waste forms for defense waste. This effort relates to choosing a suitable combination of solid form and geologic medium on the basis of risk of exposure to future generations; therefore, the focus is on post-closure considerations of deep geologic repositories. The waste forms being investigated include borosilicate glass, SYNROC, and others. Geologic media under consideration are bedded salt, basalt, and tuff. The results of our work during FY 1981 are presented in this, our second annual report. The two complementary tasks that comprise our program, analysis of waste-form dissolution and risk assessment, are described

    'Phytoremediation, the use of plants for environmental cleanup of pollutants, including toxic metals, holds the potential to allow the economic restoration of heavy metal and radionuclide contaminated sites. A number of terrestrial plants are known to naturally accumulate high levels of metals in their shoots (1--2% dry weight), and these plants have been termed metal-hyperaccumulators. Clearly, the genetic traits that determine metal-hyperaccumulation offers the potential for the development of practical phytoremediation processes. The long-term objective is to rationally design and generate plants ideally suited for phytoremediation using this unique genetic material. Initially, the strategy will focus on isolating and characterizing the key genetic information needed for expression of the metal-hyperaccumulation phenotype. Recently, histidine has been shown to play a major role in Ni hyperaccumulation. Based on this information the authors propose to investigate, at the molecular level, the role of histidine biosynthesis in Ni hyperaccumulation in Thlaspi goesingense, a Ni hyperaccumulator species.'

    ABSTRACT Clipping (i.e., harvesting aboveground plant biomass) is common in agriculture and for bioenergy production. However, microbial responses to clipping in the context of climate warming are poorly understood. We investigated the interactive effects of grassland warming and clipping on soil properties and plant and microbial communities, in particular, on microbial functional genes. Clipping alone did not change the plant biomass production, but warming and clipping combined increased the C4 peak biomass by 47% and belowground net primary production by 110%. Clipping alone and in combination with warming decreased the soil carbon input from litter by 81% and 75%, respectively. With less carbon input, the abundances of genes involved in degrading relatively recalcitrant carbon increased by 38% to 137% in response to either clipping or the combined treatment, which could weaken long-term soil carbon stability and trigger positive feedback with respect to warming. Clipping alone also increased the abundance of genes for nitrogen fixation, mineralization, and denitrification by 32% to 39%. Such potentially stimulated nitrogen fixation could help compensate for the 20% decline in soil ammonium levels caused by clipping alone and could contribute to unchanged plant biomass levels. Moreover, clipping tended to interact antagonistically with warming, especially with respect to effects on nitrogen cycling genes, demonstrating that single-factor studies cannot predict multifactorial changes. These results revealed that clipping alone or in combination with warming altered soil and plant properties as well as the abundance and structure of soil microbial functional genes. Aboveground biomass removal for biofuel production needs to be reconsidered, as the long-term soil carbon stability may be weakened. PMID:27677789

    Full Text Available This paper is first inventarisation of threatened and invasive vascular plants on the rocky grasslands situated on northern slopes of mountain Matokit and abandoned arable land in vicinity of town of Vrgorac. These sites represent a new site for the Croatian flora. This research was conducted in year 2010 and 2011. We found 11 species of threatened vascular plants that by the Red Book (Nikolić and Topić [14] and Flora Croatica Database (Nikolić [13] and 15 invasive species, according to preliminary list of invasive alien species (IAS in Croatia (Boršić et al. [3]. In this paper the habitat of some species, their distribution in Croatia, life forms and floral elements are described. It was found that threatened species occur exclusively on the rocky grassland habitat, except two species: critically endangered (CR Papaver argemone and endangered (EN Hibiscus trionum which were recorded on arable land. All inventoried invasive species, were recorded at the abandoned arable land, except the species Robinia pseudoacacia. Tendency for uncontrolled spread showed species Ailanthus altissima and Ambrosia artemisiifolia. Habitats of rocky grassland are on the stage of secondary succession (healing with the forest, and on the arable land the spread of invasive species exist (due to socio-economic changes: abandonment of agriculture and animal husbandry, and depopulation of the population. The results of these studies are contribution to the distribution map of threatened and invasive species in Croatia, and to the conservation of grassland habitat study area, as well as to preventing of the spread of invasive species.

    Grazing can dramatically affect arid grassland communities that are very vulnerable to environmental changes due to its relatively short and sparse ground coverage, low biomass, sandy soil and inter-annual precipitation found in the desert steppe. The study investigates the effects of different grazing durations on vegetation and soil properties of a desert steppe community. The experiment was conducted in Xisu Banner in Inner Mongolia with ifve treatments:CG (continuous grazing), 40UG (40 d ungrazed), 50UG (50 d ungrazed), 60UG (60 d ungrazed) and UG (ungrazed). The biomass of both shrub and annual-biennial plant communities were signiifcantly decreased by CG. Continuous grazing and 40UG signiifcantly reduced the ANPP (aboveground net primary productivity) by the end of the three year study. 60UG treatment increased soil organic carbon (OC), total nitrogen concentration (TN) and total phosphorus concentration (TP) concentrations and 50UG increased the TN and total phosphorus concentration (TK) concentrations, whereas CG, 40UG and 50UG decreased soil OC, TP and available phosphorus concentration (AP) concentrations. The perennial plant species of the desert steppe were generally tolerant for grazing. The annual-biennial plant species had large variability in ANPP because of the inter-annual precipitation. Our results highlight that inter-annual precipitation variations could strongly modify the community responses to grazing in arid ecosystems.

  2. Sustainable cities

    International Nuclear Information System (INIS)

    The Sustainable City Project, a collaboration among the cities of Portland, Oregon, and San Francisco and San Jose, California, aims at developing and implementing sustainable energy planning methods and programs for cites. For a period of two years (1989-90), the three project cities worked in parallel, yet pursued independent courses to develop appropriate sustainable urban energy practices to meet local needs and aspirations. Central to the Sustainable City Project was finding ways to manage today's urban energy needs without jeopardizing the needs of future generations. Sustainability implies that nothing should go to waste, but rather should contribute to the proper balance between the natural environment and the built environment Sustainable urban energy systems encompass more than energy efficiency and energy conservation measures: they must be diverse, flexible, self-reliant, renewable, and integrated. Since local governments make decisions affecting land use, building codes, transportation systems, waste disposal, and power plants--all of which impact energy resource use--local jurisdictions can do much to ensure their own sustainable future. This paper will present an accounting of the specific steps that each city took to determine and begin implementation of their respective approaches to sustainable energy planning, with a specific focus on the City of San Jose activities. Useful tools for facilitating community process, program planning and implementation, and quantitative analysis will also be discussed

  3. Paducah Gaseous Diffusion Plant Annual Site Environmental Report summary for 1993

    International Nuclear Information System (INIS)

    This report contains summaries of the environmental programs at Paducah Gaseous Diffusion Plant, environmental monitoring and the results, and the impact of operations on the environment and the public for 1993. The environmental monitoring program at Paducah includes effluent monitoring and environmental surveillance. Effluent monitoring is measurement of releases as they occur. Contaminants are released through either airborne emissions or liquids discharged from the plant. These releases occur as part of normal site operations, such as cooling water discharged from the uranium enrichment cascade operations or airborne releases from ventilation systems. In the event of system failure, this monitoring provides timely warning so that corrective action can be taken before releases reach an unsafe level. Environmental surveillance tracks the dispersion of materials into the environment after they have been released. This involves the collection of samples from various media, such as water, soil, vegetation, and food crops, and the analysis of these samples for certain radionuclides, chemicals, and metals

    Chronic industrial fluoride toxicosis in the forms of dental, skeletal and non-skeletal fluorosis was investigated in 162 villagers (94 males and 78 females) above 15 years of age living in the vicinity of superphosphate fertilizer plants located approximately 12 km south of Udaipur city of Rajasthan, India. Out of these villagers, 90 (55.5%) and 29 (18.0%) were found to be afflicted with mild to severe dental and skeletal fluorosis, respectively. Dental fluorosis characterized with light to deep-brownish bilaterally striated horizontal lines, pits or patches and fine dots or granules was noted on incisor teeth of villagers. Irregular wearing, excessive corrosions (abrasions), dark-brownish pigmentation of exposed cementum and dentine material, diastem as between teeth, pronounced loss of tooth supporting bone with recession and bulging of gingiva (gum) were also present in subjects of older age group (>55 years). Among 29 (18.0%) individuals, mild to moderate manifestations of skeletal fluorosis such as crippling, kyphosis, invalidism and genu-varum syndrome were found. In these fluorotic subjects pain/rigidity in major joints viz. neck, back, hip, knee and shoulder was also found. None of the fluorotic subjects showed evidence of genu-valgum syndrome. Other signs of chronic industrial fluoride intoxication in soft tissues (non-skeletal fluorosis) included colic, intermittent diarrhoea or constipation, bloating, polyuria and polydipsia. These findings indicate that surrounding environment of superphosphate fertilizer plants is contaminated with fluoride emission, which in turn is causing diverse ill health effects in humans which are discussed.

    As a result of the accident at the Fukushima Daiichi Nuclear Power Plant (FNPP) on 11 March 2011, a huge amount of radionuclides, including radiocesium, was released and spread over a wide area of eastern Japan. Although three years have passed since the accident, residents around the FNPP are anxious about internal radiation exposure due to radiocesium. In this study, we screened internal radiation exposure doses in Iwaki city of Fukushima prefecture, using a whole-body counter. The first screening was conducted from October 2012 to February 2013, and the second screening was conducted from May to November 2013. Study participants were employees of ALPINE and their families who underwent examination. A total of 2,839 participants (1,366 men and 1,473 women, 1-86 years old) underwent the first screening, and 2,092 (1,022 men and 1,070 women, 1-86 years old) underwent the second screening. The results showed that 99% of subjects registered below 300 Bq per body in the first screening, and all subjects registered below 300 Bq per body in the second screening. The committed effective dose ranged from 0.01-0.06 mSv in the first screening and 0.01-0.02 mSv in the second screening. Long-term follow-up studies are needed to avoid unnecessary chronic internal exposure and to reduce anxiety among the residents by communicating radiation health risks.

  8. Performance model and annual yield comparison of parabolic-trough solar thermal power plants with either nitrogen or synthetic oil as heat transfer fluid

    International Nuclear Information System (INIS)

    Highlights: • N2 is proposed as heat transfer fluid for parabolic-trough solar power plants. • N2 is a clean fluid that can avoid some of the limitations of synthetic oils. • 2 performance models of parabolic-trough plants with N2 or oil have been developed. • 50 MWe parabolic-trough plants with 6 h of storage have been simulated. • Similar annual electricity yields have been obtained for N2 and synthetic oil. - Abstract: The majority of commercial parabolic-trough plants in the world operate with synthetic oil as heat transfer fluid in the solar field. However, the synthetic oils that are available at affordable cost present some challenges such as their flammability, environmental toxicity and a temperature limitation of around 400 °C. As alternative, this work proposes the use of pressurized nitrogen as heat transfer fluid. In order to analyze the feasibility of this technology, a comparison between a plant with nitrogen and a conventional plant with synthetic oil has been carried out. In both cases, 50 MWe parabolic-trough plants with 6 h of thermal storage are used as reference. A performance model including the solar field, the thermal storage system and the power block has been developed for each plant in the TRNSYS simulation software. This paper also describes the specifications, design and sizing of the solar field and explains the basic operation strategy applied in each model. Both annual simulations have been performed considering the same location, Almería (Spain), and meteorological data. In summary, the results show that similar net annual electricity productions can be attained for parabolic-trough plants with the same collection area using either nitrogen or synthetic oil as heat transfer fluid

  9. Biological recipient control at the Oskarshamn nuclear power plant. Annual report for 2011

    International Nuclear Information System (INIS)

    Potential ecosystem effects caused by the effluent cooling water from the Simpevarp nuclear power plant, close to Oskarshamn on the Swedish coast of the Baltic Proper, are monitored in yearly surveys using gillnets and fyke nets. Fishing is undertaken at several sites in a coastal gradient starting at the location of the emitted cooling water, and in a reference area 100 km north of the recipient. Soft bottom macro fauna and macro vegetation are monitored both in the gradient and in the reference area. Fish mortality due to entrapment in the cooling water system and commercial landings are monitored to assess the effects on the local fishery. The water used for cooling is normally heated by 10-12 deg C when passing through the power plant. In sheltered parts of the recipient bay of Hamnefjaerden, the surface water was 4-6 deg C warmer in April-November 2011 than in the reference area comparable reference areas and the emitted water occasionally exceeded 30 deg C in the summer. Fish losses in the cooling water rinsing system were dominated by Baltic herring. Effects on abundances at the population level are estimated to be small, but local effects cannot be ruled out. Perch (Perca fluviatilis), roach (Rutilus rutilus) and silver bream (Blicca bjoerkna) dominated the catches in the surveys with gillnets in Hamnefjaerden, as well as in the archipelago surrounding the power plant. Perch abundances increased in these areas. Catches of roach decreased close to the power plant, but also in the reference area. Perch in the gillnet catches were younger and grew faster close to the power plant than in the reference area. Abnormal gonads, previously observed at high frequencies in perch and roach in Hamnefjaerden, were rare in the 2011 sampling. The abundance of young of the year perch in the recipient did not change over time. The size of the perch fry however, increased in Hamnefjaerden, as well as in the local reference area.

  10. Middlesex Sampling Plant and Middlesex Municipal Landfill annual site environmental report, Middlesex, New Jersey: Calendar year 1986

    International Nuclear Information System (INIS)

    During 1986, the environmental monitoring program was continued at the former Middlesex Sampling Plant (MSP) and former Middlesex Municipal Landfill (MML) sites, located in the Borough of Middlesex, New Jersey. The MSP and MML sites are part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a DOE program to decontaminate or otherwise control sites where residential radioactive materials remain from either the early years of the nation's atomic energy program or commercial operations causing conditions that Congress has mandated DOE to remedy. The monitoring program at the MSP and MML measures radon gas concentrations in air; external gamma radiation levels; and uranium and radium concentrations in surface water, groundwater, and sediment. To verify that sites are in compliance with the DOE radiation protection standard (100 mrem/yr) and to assess their potential effect on public health, the radiation dose was calculated for the maximally exposed individual. Based on the conservative scenarios described in the report, this individual, at the MSP, would receive an annual external exposure approximately equivalent to 10 percent of the DOE radiation protection standard. By comparison, the incremental dose received from living in a brick house versus a wooden house is about the same. At the MML, the annual external exposure to the maximally exposed individual would be less than 1% of the standard. The cumulative dose to the population within an 80-km (50-mi) radius of the sites that would result from radioactive materials present at the MSP and MML would be indistinguishable from the dose that the same population would receive from naturally occurring radioactive sources. Results of the 1986 monitoring show that the MSP and MML are in compliance with the DOE radiation protection standard. 14 refs., 13 figs., 23 tabs

    Eight plant species - Acacia melanoxylon, Bauhinia malabarica, Bougain-villea glabra, Calotropis procera, Catharanthus roseus, Eucalyptus globulus, Ipomoea fistulosa and Peltophorum pterocarpum - were collected from a newly established suburb colony of Lucknow city, where the major pollutant is dust, to study the dust cleansing efficiency of the plant canopy and also to establish the correlation between the leaf morphological characteristics and their dust trapping potential. The dust load, in milligrams per square centimeter of leaf surface, was measured and related to foliar epidermal and cuticular characteristics, and morphological features.

  13. Quantification of potentially toxic elements in sewage and sludge from treatment plants in the cities of Campinas and Jaguariuna using synchrotron radiation total reflection X-ray fluorescence

    International Nuclear Information System (INIS)

    The rapid urban and industrial development in last decades has brought as one of the consequences, changes in the environment. The lack of planning of city growth is, today, one of the major causes of water pollution including residential, industrial, agricultural, and hospital waste. The metals contamination is a major problem, causing serious changes to the environment, causing harm to human health. The sludge generated at sewage treatment plants, is an important source of nutrients and organic matter, and therefore it can also be reused mainly for agricultural use, since contaminants are removed. The cities of Campinas and Jaguariuna are inserted in the Campinas Metropolitan Region (CMR), one of the most dynamic regions in the Brazilian economy. Therefore, to study the anthropogenic influences of the cities, evaluated the quality of raw and treated effluent and the sludge generated in sewage treatment plants, especially with regard to heavy metals. Measurements of metals were performed by Synchrotron Radiation Total Reflection X-ray Fluorescence. For treated effluent data were compared to CONAMA 357 law and Cr, Mn, Fe, Ni, Cu, Zn, Ba and Pb showed concentrations in according with the law. To reuse in agriculture the contents were compared to the limits defined by CETESB and some elements had concentrations above to the permitted preventing its reuse. For sludge, Cr, Ni, Cu, Zn, Ba and Pb, in the two treatment plants studied, the concentrations were lower than the maximum permissible values established by CONAMA 375 law allowing the sludge application sludge on agricultural land.

  14. What makes a perennial a perennial? A meta-analysis of allocation patterns and functional traits in congeneric annual and perennial plant

    Vico, Giulia; Manzoni, Stefano; Weih, Martin

    2014-05-01

    Currently, a large fraction of food, fiber, and feed is provided by annual crops - in particular annual grains. A shift from annual to perennial crops has been advocated to move towards a more sustainable agriculture. While providing lower yields than annuals, perennial crops are often assumed to reduce soil erosion, promote soil health, and be able to achieve higher water and nitrogen use efficiency, primarily through higher allocation below ground. Nevertheless, quantifications of these benefits are still scarce and often inconclusive, as well as mostly limited to first-year perennials. Here we consider congeneric annual and perennial species pairs, for which measured productivity, resource allocation, and resource use efficiency are available in the literature, in search for a signature of life-history (i.e., annuality vs. perenniality) on plant allocation, traits, and agronomic performances. A new database of allocation strategies and functional traits of these congeneric species is developed, covering more than 25 genera of agronomical and ecological relevance, including wild and domesticated species, as well as new hybrids, grown under a variety of conditions. Some general patterns emerge. Perennials have lower biomass allocation to reproductive structures (as expected), and generally higher root-to-shoot biomass ratio, potentially promoting soil C accumulation. Patterns in nitrogen tissue concentration and resource use efficiencies are less clear, due to the limited available data. Our analyses highlight a paucity of comprehensive studies, hampering our understanding of the long-term implications of a shift to perennial crops for ecosystem hydrologic and biogeochemical cycles.

  15. The causes of selection on flowering time through male fitness in a hermaphroditic annual plant.

    Austen, Emily J; Weis, Arthur E

    2016-01-01

    Flowering is a key life-history event whose timing almost certainly affects both male and female fitness, but tests of selection on flowering time through male fitness are few. Such selection may arise from direct effects of flowering time, and indirect effects through covariance between flowering time and the environment experienced during reproduction. To isolate these intrinsically correlated associations, we staggered planting dates of Brassica rapa families with known flowering times, creating populations in which age at flowering (i.e., flowering time genotype) and Julian date of flowering (i.e., flowering time environment) were positively, negatively, or uncorrelated. Genetic paternity analysis revealed that male fitness was not strongly influenced by seasonal environmental changes. Instead, when age and date were uncorrelated, selection through male fitness strongly favored young age at flowering. Strategic sampling offspring for paternity analysis rejected covariance between sire age at flowering and dam quality as the cause of this selection. Results instead suggest a negative association between age at flowering and pollen competitive ability. The manipulation also revealed that, at least in B. rapa, the often-observed correlation between flowering time and flowering duration is environmental, not genetic, in origin. PMID:26596860

    The environmental monitoring program, which began in 1980, was continued in 1988 at the former Middlesex Sampling Plant (MSP) site, located in the Borough of Middlesex, New Jersey. The MSP site is part of the Formerly Utilized Site Remedial Action Program (FUSRAP), a Department of Energy (DOE) program to decontaminate or otherwise control sites where residual radioactive materials remain either from the early years of the nation's atomic energy program or from commercial operations causing conditions that Congress has mandated DOE to remedy. The environmental monitoring program is carried out by Bechtel National, Inc. (BNI), project management contractor for FUSRAP. The monitoring program at the MSP measures radon concentrations in air; external gamma radiation levels; and uranium and radium concentrations in surface water, groundwater, and sediment. To verify that the site is in compliance with the DOE radiation protection standard (100 mrem/yr) and to assess its potential effect on public health, the radiation dose was calculated for a hypothetical maximally exposed individual. Results of the 1988 monitoring show that the MSP is in compliance with applicable DOE radiation protection standards and with applicable requirements specified by New Jersey Department of Environmental Protection groundwater permits. 17 refs., 15 figs., 21 tabs

    International Nuclear Information System (INIS)

    'During the funding period of 1996--1997, the authors explored the utility of multi-nuclear, two-dimensional nuclear magnetic resonance (NMR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) for a comprehensive analysis of barley root exudates collected under Fe sufficient and deficient conditions. As both structural and quantitative information was obtained directly from crude root exudates using this approach, no tedious sample fractionation was necessary, which will greatly facilitate future chemical characterization of root exudates in general. They found that the phytosiderophore mugineic acids (including 2'-deoxymugineic acid, mugineic acid, and 3-epi-hydroxymugineic acid) were readily identified and quantified in crude exudate samples along with a number of amino and organic acids. The amount of mugineic acids excreted was correlated positively with the extent of Fe deficiency with 3-epi-hydroxymugineic acid being the most prominent component. The total Fe chelating capacity was also measured using the ferrozine assay and compared with the production of the mugineic acids. They were surprised to find that the mugineic acids may account for a part of the Fe chelating capacity, especially under mild and moderatley Fe deficient conditions. Lactate, alanine, y-aminobutyrate, malate, and glycinebetaine collectively may contribute to a significant fraction of the Fe chelating capacity. In light of the known stimulatory effect of alanine and citrate on metal availability to algae (Campell, 1995), the function of these low molecular weight metabolites as vehicles for Fe or metal uptake in general warrant further investigation.

    Urban areas are increasingly at risk from climate change with negative impacts predicted for human health, the economy and ecosystems. These risks require responses from cities, to improve the resilience of their infrastructure, economy and environment to climate change. Policymakers need to understand what is already being spent on adaptation so that they can make more effective and comprehensive adaptation plans. Through the measurement of spend in the newly defined 'Adaptation Economy' we analysis the current efforts of 10 global megacities in adapting to climate change. These cities were chosen based on their size, geographical location and their developmental status. The cities are London, Paris, New York, Mexico City, Sao Paulo, Beijing, Mumbai, Jakarta, Lagos and Addis Ababa. It is important to study a range of cities in different regions of the world, with different climates and at different states of socio-economic development. While in economic terms, disaster losses from weather, climate and geophysical events are greater in developed countries, fatalities and economic losses as a proportion of GDP are higher in developing countries. In all cities examined the Adaptation Economy is still a small part of the overall economy accounting for a maximum of 0.3% of the Cities total GDP (GDPc). The differences in total spend are significant between cities in developed and rapidly emerging countries, compared to those in developing countries with a spend ranging from £16 million to £1,500 million. Comparing key sub sectors, we demonstrate that there are distinctive adaptation profiles with developing cities having a higher relative spend on health, while developed cities have a higher spend on disaster preparedness, ICT and professional services. Comparing spend per capita and as a percentage of GDPc demonstrates even more clearly disparities between the cities in the study; developing country cities spend half as much as a proportion of GPCc in some cases, and

  4. Potential plant biomass estimation through field measurement and vegetation cover mapping using ALOS satellite imagery: Case study of Fujiyoshida City, Japan

    International Nuclear Information System (INIS)

    Biomass is a renewable energy source that is produced from living or recently living biological material. Vegetation type and biomass are considered important components that affect biosphere-atmosphere interactions. The ground assessment of biomass, however, has been found to be insufficient due to the limited spatial extent of surveys. This study aims to integrate field measurements with satellite remote sensing data for regional biomass mapping in Fujiyoshida City, Japan. Fujiyoshida City is situated on the northern slope of Mt. Fuji and includes a large area of forest land, named Onshirin Forest. From 2011 to 2012, a field survey was conducted to calculate the biomass potential in situ as ground-truthed data. After fieldwork, ortho-rectified ALOS data with an AVNIR-2 scene (22 May 2008) was used to map the vegetation cover types. Japanese larch, Japanese red pine, mixed forest, other forest, grass, bare soil and roads, and buildings were identified using supervised classification. The total plant biomass was 163,252 tons. The biomass potential estimate from field measurements was extrapolated to the large forest area in Fujiyoshida City to estimate the potential plant biomass of specific vegetation cover types

    The monitoring program at the Middlesex Sampling Plant (MSP) and Middlesex Municipal Landfill (MML) measures uranium and radium concentrations in surface water, groundwater, and sediment; radon gas concentrations in air; and external gamma radiation dose rates. Potential radiation doses to the public are also calculated. During 1985, the highest annual average radon levels in air at the MML and MSP were 10% and 17%, respectively, of the Derived Concentration Guides (DCG). The highest annual average gamma dose rate at the MSP was 167 mrem/y; at the MML the highest annual average dose rate was 13 mrem/y. The highest average annual concentrations of uranium in surface water monitored at the MSP and MML were 13% and 1%, respectively, of the DOE DCG. The highest annual average concentrations of 226Ra in surface water were 3.3 and 0.8%, respectively, of the applicable DOE DCG. The highest annual average uranium concentration in groundwater at the MSP was about 9% of the DCG; the highest 226Ra concentration was 0.7% of the respective DCG. The corresponding values for the MML were 0.5 and 3.3%. The highest annual average concentrations of uranium and 226Ra in sediments at the MSP were 7.7 and 3.5 pCi/g, respectively. The highest uranium concentration at the MML was 3.3 pCi/g, while the highest 226Ra concentration was 0.7 pCi/g. The calculated total radiation dose to the maximally exposed individual at the MSP, considering several pathways, was 10.5 mrem or 11% of the radiation protection standard; at the MML, it was 0.14 mrem or less than 1% of the radiation protection standard

    1975-01-01

    A characteristic difference in calcium oxalate crystal patterns in leaves of roadside trees planted in relatively unpolluted northern parts of Itami City and in parts of the city polluted by automobile exhaust was discovered. The species of trees examined were Ginkgo biloba, Salix babylonica, Aphananthe aspera, Robinia pseudoacacia, and Poplar. The leaves of trees grown in relatively less air polluted areas displayed crystal aggregates of calcium oxalate (50-80 micron) that were arranged in rows on both sides of the central vein; some scattered crystal aggregates between veins were observed. Trees grown in air polluted areas showed irregular crystal patterns and more scattering of the crystals between veins. The cause of the observed differences in the pattern of crystal aggregates was attributed to the difference in metabolism of trees under different environmental conditions. Air pollutants disturb the normal metabolism of the tree and cause hyperproduction of calcium oxalate.

    Coal-fired power plants emissions impact the air quality and human health. Of great significance is assessment of solid airborne particles emissions from those plants and distance of their transportation. The article presents the results of air pollution assessment in the zone of coal-fired power plant (Karaganda City) using snow survey. Based on the mass of solid airborne particles deposited in snow, time of their deposition on snow at the distance from 0.5 to 4.5 km a value of dust load has been determined. It is stated that very high level of pollution is observed at the distance from 0.5 to 1 km. there is a trend in decrease of dust burden value with the distance from the stacks of coal-fired power plant that may be conditioned by the particle size and washing out smaller ash particles by ice pellets forming at freezing water vapour in stacks of the coal-fired power plant. Study in composition of solid airborne particles deposited in snow has shown that they mainly contain particulates of underburnt coal, Al-Si- rich spheres, Fe-rich spheres, and coal dust. The content of the particles in samples decreases with the distance from the stacks of the coal-fired power plant.

    The city of Aldama, Chihuahua, Mexico is located 30 km NNE of Chihuahua city. Three high-volume collectors with PM10 heads were placed in specific locations in Aldama during the year 2011 to measure radioisotope concentrations in the air. The city area of 16 km² was divided into 64 squares of 500 × 500 m. At the vertices of the grid, silt samples were taken between January and June 2011, before the rains began. The concentrations of natural, cosmogenic, and anthropogenic radioactive isotopes were calculated in both filters and silts samples. The isotopes selected for the measurement were ²³⁸U, ²³²Th, (7)Be, ¹³⁷Cs, and ⁴⁰K. Measurements of PM10 and silts were performed during 2011, coinciding with the accident at Fukushima, Japan, on March 11. For this reason, we could see the ¹³⁷Cs in PM10 increase between April and July; with the arrival of the rains, the ¹³⁷Cs concentration began to decrease in the air. The concentration of PM10 measured by the equipment located at the Mexican Uranium plant (URAMEX, initials in Spanish) that was processing radioactive ores exceeded the standard values in February and March, when the air velocity increases. At City Hall, the concentration of PM10 surpassed the value of the standard between May and July. This increased concentration is likely due to increased automobile traffic because City Hall is located in the city center. At a private home, the concentration of PM10 surpassed the standard on several days during the year because the home is located on the outskirts of the city, where most of the streets are not paved. Due to the high concentrations of PM10, especially at the collection point located at the private home, it is necessary to start taking steps to mitigate their spread before they cause health problems in the younger population and in older adults.

  12. Marginal cost pricing for coal fired electricity in coastal cities of China:The case of Mawan Electricity Plant in Shenzhen City, China

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    By developing a GDMOD model to estimate the environmental externalities associated with electricity generation, this project provides a detailed analysis of the damages and costs caused by different pollutants at varying distances from the Mawan Electricity Plant in Shenzhen, China. The major findings of this study can be summarized that (1) environmental damages caused by electricity production are large and are mainly imposed on regions far away from the electricity plant; (2) air pollution is the most significant contributor to the total damages, and SO2, NOx, and particulate matter are the three major pollutants with highest damages; (3) the damages caused per unit of particulate, NOx, and SO2 emissions are much higher than pollution treatment and prevention costs. The research results of this project showed that China needs to have a more effective levy system on SO2, and a more manageable electricity tariff mechanism to internalize the environmental externalities. The results have also implications for pollution control strategies, compensation schemes as well as emission trading arrangements.

    The carbon isotopic composition (delta13C) of plants can reveal the isotopic carbon content of the atmosphere in which they develop. The delta13C values of air and plants depend on the amount of atmospheric fossil fuel CO2, which is chiefly emitted in urban areas. A new indicator of CO2 pollution is tested using the delta13C variation in a C4 grass: Eleusine indica. A range of about 4 per thousand delta units was observed at different sites in Cotonou, the largest city in the Republic of Benin. The highest delta13C values, from -12 per thousand to -14 per thousand, were found in low traffic zones; low delta13C values, from -14 per thousand to -16 per thousand, were found in high traffic zones. The amount of fossil fuel carbon assimilated by plants represented about 20% of the total plant carbon content. An overall decrease in plant delta13C values was observed over a four-year monitoring period. This decrease was correlated with increasing vehicle traffic. The delta13C dataset and the corresponding geographical database were used to map and define zones of high and low 13C-depleted CO2 emissions in urban and sub-urban areas. The spatial distribution follows dominant wind directions, with the lowest emission zones found in the southwest of Cotonou. High CO2 emissions occurred in the north, the east and the center, providing evidence of intense anthropogenic activity related to industry and transportation.

  15. How healthy is urban horticulture in high traffic areas? Trace metal concentrations in vegetable crops from plantings within inner city neighbourhoods in Berlin, Germany

    International Nuclear Information System (INIS)

    Food production by urban dwellers is of growing importance in developing and developed countries. Urban horticulture is associated with health risks as crops in urban settings are generally exposed to higher levels of pollutants than those in rural areas. We determined the concentration of trace metals in the biomass of different horticultural crops grown in the inner city of Berlin, Germany, and analysed how the local setting shaped the concentration patterns. We revealed significant differences in trace metal concentrations depending on local traffic, crop species, planting style and building structures, but not on vegetable type. Higher overall traffic burden increased trace metal content in the biomass. The presence of buildings and large masses of vegetation as barriers between crops and roads reduced trace metal content in the biomass. Based on this we discuss consequences for urban horticulture, risk assessment, and planting and monitoring guidelines for cultivation and consumption of crops. - Highlights: ► Traffic-related pollutant deposition as important pathway for crop contamination. ► Heavy metal content often over EU standards for lead concentration in food crops. ► ‘Grow your own’ food in inner cities not always ‘healthier’ than supermarket products. ► No support for generalisations of crops as ‘risky high’ or ‘safe low’ accumulators. - Higher overall traffic burden increased, while the presence of buildings and large masses of vegetation as barriers between crops and roads reduced heavy metal content in crop biomass.

    Full Text Available The consumption of dietary supplements and herbal mixtures to promote weight loss is a common practice in the West. This study was undertaken in Mexico City, surveying stores selling "natural products" at subway stations. The aims of this paper were as follows: to compile a record of plant products marketed as slimming aids and of retailer perceptions of these products; to review the pharmacological and ethnobotanical literature on the species declared; and to create an optical micrograph of a subset of products to verify the accuracy of the list of component plant species shown on the labels. We applied the techniques of observation, semi-structured interviews and free-listing at the retail stores. Results are presented for the 75 species recorded in the 41 weight-loss products surveyed, showing which plant parts are used, the geographical distribution of the species, pharmacological effects, dosage, route of administration and method of preparation, as well as ethnobotanical information derived from fieldwork. We discuss the values assigned to the species used. Microscopic analyses revealed that many of the plant ingredients declared were absent, highlighting the need for greater quality control and safety of these herbal remedies.

    Yiwu is a county-level city in the central part of Zhejiang Province with no obvious geographical advantage or traditional industrial foundation. And yet it has dazzled the country with its sizzling economic figures. The city posted an annual growth of 16 percent in GDP in 2003 on 15.6bn yuan {US$1.9 billion)from the previous year. Its average annual GDP increase from 1978 to 1999 reached 18.5 percent. Exports from Yiwu were valued at US$734 million last year, compared with US$390m for 2002. So what is it about Yiwu that has molded the city into such handsome shape?

    2016-04-01

    Soil and plant samples were collected from sewage and tubewell irrigated sites from three industrially different cities of Punjab (India) viz. Ludhiana, Jalandhar and Malerkotla. The extent of lead (Pb) pollution was assessed with respect to background concentration of tubewell irrigation. In sewage irrigated surface soil layer (0-15 cm), the extent of Pb accumulation was 4.61, 4.20 and 2.26 times higher than those receiving tubewell irrigation sites in Ludhiana, Jalandhar and Malerkotla, respectively. Multiple regression analysis showed that soil pH, organic carbon, calcium carbonate and clay were significant soil parameters explaining the variation in available soil Pb. The mean Pb content in plants receiving sewage irrigation was 4.56, 5.48 and 2.72 times higher than tubewell irrigation in Ludhiana, Jalandhar and Malerkotla, respectively. The content of Pb in plants receiving sewage irrigation revealed that, assuming a weekly consumption of 500-1000 g of vegetables grown on sewage irrigated soils by an adult of 70 kg body weight, the Pb intake may far exceed the World Health Organization proposed tolerable weekly intake of Pb.

    2016-10-01

    We assessed whether diversity in plant hydraulic traits can explain the observed diversity in plant responses to water stress in seasonally dry tropical forests (SDTFs). The Ecosystem Demography model 2 (ED2) was updated with a trait-driven mechanistic plant hydraulic module, as well as novel drought-phenology and plant water stress schemes. Four plant functional types were parameterized on the basis of meta-analysis of plant hydraulic traits. Simulations from both the original and the updated ED2 were evaluated against 5 yr of field data from a Costa Rican SDTF site and remote-sensing data over Central America. The updated model generated realistic plant hydraulic dynamics, such as leaf water potential and stem sap flow. Compared with the original ED2, predictions from our novel trait-driven model matched better with observed growth, phenology and their variations among functional groups. Most notably, the original ED2 produced unrealistically small leaf area index (LAI) and underestimated cumulative leaf litter. Both of these biases were corrected by the updated model. The updated model was also better able to simulate spatial patterns of LAI dynamics in Central America. Plant hydraulic traits are intercorrelated in SDTFs. Mechanistic incorporation of plant hydraulic traits is necessary for the simulation of spatiotemporal patterns of vegetation dynamics in SDTFs in vegetation models.

    Hosseini, S. A.

    In order to determine contribution of plant in radioiodine uptake, soil-to-plant concentration ratios of radioiodine from soil to agricultural crops are needed and so we carried out radiotracer experiments. The mean values of concentration ratio (on a wet weight basis) of radioiodine from soil to edible parts of crops in podzol were as follows: lentil, 0.054; pea, 0.012; wheat, 0.040 and red bean, 0.068. The mean values of the radioiodine concentrations in plant parts of red bean, lentil, wheat and pea (on a wet weight basis) were 4.32, 3.43, 2.64 and 1.0 kBq kg-1, respectively. We also studied the distribution of the radioiodine in the crops. There was a tendency for the concentration ratio of stem to be higher than those of root and leaves. A very high concentration ratio was found for root of red bean; because this plant was studied at a growth stage different from that of the other plants. The data obtained in this study should be useful in assessing the behavior of long-lived 129I (half life: 1.57x107 year) released from nuclear fuel cycle.

    Four common greening shrub species (i. e. Ligustrum quihoui, Buxus bodinieri, Berberis xinganensis and Buxus megistophylla) in Xi'an City were selected to develop the highest correlation and best-fit estimation models for the organ (branch, leaf and root) and total biomass against different independent variables. The results indicated that the organ and total biomass optimal models of the four shrubs were power functional model (CAR model) except for the leaf biomass model of B. megistophylla which was logarithmic functional model (VAR model). The independent variables included basal diameter, crown diameter, crown diameter multiplied by height, canopy area and canopy volume. B. megistophylla significantly differed from the other three shrub species in the independent variable selection, which were basal diameter and crown-related factors, respectively. PMID:24765849

    The Tertiary sedimentary basins are distributed along the eastern coast of Korean Peninsula. The northernmost Bukpyeong Basin is located in Donghae City, Gangwon-do Province, Korea. The Bukpyeong Basin consists of Bukpyeong Formation and Dogyeongri Conglomerate in ascending order. The geologic age of Bukpyeong Formation has been suggested as from Early Miocene to Pliocene, In particular, Lee & Jacobs (2010) suggested the age of the Bukpyeong Formation as late Early Miocene to early Middle Miocene based on the fossils of rodent teeth. Sedimentary environment has been thought as mainly fresh water lake and/or swamp partly influenced by marine water. Lately, new outcrops of Bukpyeong Formation were exposed during the road construction and abundant fossil plants were yielded from the newly exposed outcrops. As a result of palaeobotanical studies 47 genera of 23 families have been found. This fossil plant assemblage is composed of gymnosperms and dicotyledons. Gymnosperms were Pinaceae (e.g., Pinus, Tsuga), Sciadopityaceae (e.g., Sciadopitys) and Cupressaceae with well-preserved Metasequoia cones. Dicotyledons were deciduous trees such as Betulaceae (e.g., Alnus, Carpinus) and Sapindaceae (e.g., Acer, Aesculus, Sapindus), and evergreen trees such as evergreen Fagaceae (e.g., Castanopsis, Cyclobalanopsis, Pasania) and Lauraceae (e.g., Cinnamomum, Machilus). In addition, fresh water plants such as Hemitrapa (Lytraceae) and Ceratophyllum (Ceratophyllaceae) were also found. The fossil plant assemblage of the Bukpyeong Formation supported the freshwater environment implied by previous studies. It can be suggested that the palaeoflora of Bukpyeong Formation was oak-laurel forest with broad-leaved evergreen and deciduous trees accompanying commonly by conifers of Pinaceae and Cupressaceae under warm-temperate climate.

  20. Controlled production of cellulases in plants for biomass conversion. Annual report, March 11, 1997--March 14, 1998

    Energy Technology Data Exchange (ETDEWEB)

    Danna, K.J.

    1998-06-01

    The goal of this project is to facilitate conversion of plant biomass to usable energy by developing transgenic plants that express genes for microbial cellulases, which can be activated after harvest of the plants. In particular, the feasibility of targeting an endoglucanase and a cellobiohydrolase to the plant apoplast (cell wall milieu) is to be determined. To avoid detrimental effects of cellulose expression in plants, enzymes with high temperature optima were chosen; the genes for these enzymes are from thermophilic organisms that can use cellulose as a sole energy source. During the past year (year 2 of the grant), efforts have been focused on testing expression of endoglucanase E{sub 1}, from Acidothermus cellulolyticus, in the apoplast of both tobacco suspension cells and Arabidopsis thaliana plants. Using the plasmids constructed during the first year, transgenic cells and plants that contain the gene for the E{sub 1} catalytic domain fused to a signal peptide sequence were obtained. This gene was constructed so that the fusion protein will be secreted into the apoplast. The enzyme is made in large quantities and is secreted into the apoplast. More importantly, it is enzymatically active when placed under optimal reaction conditions (high temperature). Moreover, the plant cells and intact plants exhibit no obvious problems with growth and development under laboratory conditions. Work has also continued to improve binary vectors for Agrobacterium-mediated transformation, to determine activity of E{sub 1} at various temperatures, and to investigate the activity of the 35S Cauliflower Mosaic Virus promoter in E. coli. 9 figs.

    The presence of enteric bacteria in water bodies is a cause of public health concerns, either by directly causing water- and food-borne diseases, or acting as reservoirs for antibiotic resistance determinants. Water is used for crop irrigation; and sediments and aquatic plants are used as fertilizing supplements and soil conditioners. In this work, the bacterial load of several micro-environments of the urban lake of Xochimilco, in Mexico City, was characterized. We found a differential distribution of enteric bacteria between the water column, sediment, and the rhizoplane of aquatic plants, with human fecal bacteria concentrating in the sediment, pointing to the need to assess such bacterial load for each micro-environment, for regulatory agricultural purposes, instead of only the one of the water, as is currently done. Resistance to tetracycline, ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole was common among Escherichia coli isolates, but was also differentially distributed, being again higher in sediment isolates. A distinct distribution of chloramphenicol minimum inhibitory concentrations (MIC) among these isolates suggests the presence of a local selective pressure favoring lower MICs than those of isolates from treated water. Fecal bacteria of human origin, living in water bodies along with their antibiotic resistance genes, could be much more common than typically considered, and pose a higher health risk, if assessments are only made on the water column of such bodies.

    A better understanding on the partitioning behavior of mercury (Hg) during coal combustion in large-scale coal-fired power plants is fundamental for drafting Hg-emission control regulations. Two large coal-fired utility boilers, equipped with electrostatic precipitators (ESPs) and a wet flue gas desulfurization (WFGD) system, respectively, in coal energy-dominant Huainan City, China, were selected to investigate the distribution and fate of Hg during coal combustion. In three sampling campaigns, we found that Hg in bottom ash was severely depleted with a relative enrichment (RE) index removal efficiencies of ESPs, WFGD, and ESPs + WFGD were 17-32, 10-29, and 36-46%, respectively. The Hg-emission factor of studied boilers was in a high range of 0.24-0.29 g Hg/t coal. We estimated that Hg emissions in all Huainan coal-fired power plants varied from 1.8 Mg in 2003 to 7.3 Mg in 2010. PMID:26883032

    Full Text Available Human exposure to heavy metals is a growing concern across Nigerian urban settings due to potential danger from consuming plants grown on contaminated soils. This study assessed the contents of lead and cadmium in soil and basil (Ocimum basilicum Lamiaceae grown by vegetable farmers in Ojo Local Government Area of Lagos State, Nigeria. Using grid method, 36 points were located to collect soil samples at 0–15 and 15–30 cm depths, while plant samples were also collected simultaneously. The contents of lead and cadmium in soil and plants were determined and results were subjected to descriptive statistics while the transfer factor (TF was calculated. Lead ranged from 1.85 mg kg−1 at the topsoil to 2.54 mg kg−1 at subsoil. Cadmium varied from 0.99 mg kg−1 at the topsoil to 1.41 mg kg−1 at subsoil. Average TF were 0.21 for Pb and 0.35 for cadmium. Distribution of lead and cadmium increased in order leaf < stem < root indicating that the root of basil may be useful in bioremediation of metal-contaminated soils. Although, the levels of lead and cadmium contents in the basil leaf are lower than other parts, there could be accumulation of these metals through long-term consumption of the leaf.

  11. Nuclear Energy Research Initiative. Risk Informed Assessment of Regulatory and Design Requirements for Future Nuclear Power Plants. Annual Report

    International Nuclear Information System (INIS)

    The overall goal of this research project is to support innovation in new nuclear power plant designs. This project is examining the implications, for future reactors and future safety regulation, of utilizing a new risk-informed regulatory system as a replacement for the current system. This innovation will be made possible through development of a scientific, highly risk-informed approach for the design and regulation of nuclear power plants. This approach will include the development and.lor confirmation of corresponding regulatory requirements and industry standards. The major impediment to long term competitiveness of new nuclear plants in the U.S. is the capital cost component--which may need to be reduced on the order of 35% to 40% for Advanced Light Water Reactors (ALWRs) such as System 80+ and Advanced Boiling Water Reactor (ABWR). The required cost reduction for an ALWR such as AP600 or AP1000 would be expected to be less. Such reductions in capital cost will require a fundamental reevaluation of the industry standards and regulatory bases under which nuclear plants are designed and licensed. Fortunately, there is now an increasing awareness that many of the existing regulatory requirements and industry standards are not significantly contributing to safety and reliability and, therefore, are unnecessarily adding to nuclear plant costs. Not only does this degrade the economic competitiveness of nuclear energy, it results in unnecessary costs to the American electricity consumer. While addressing these concerns, this research project will be coordinated with current efforts of industry and NRC to develop risk-informed, performance-based regulations that affect the operation of the existing nuclear plants; however, this project will go farther by focusing on the design of new plants

    Full Text Available Eight medicinal plants and soil samples from the Malnad area of Karnataka in South India (N 13°29′35.4″; E 75°18′02.4″ were analysed for activity concentrations of natural and artificial radionuclides using HPGe gamma spectrometry. The average annual committed effective dose (AACED due to the ingestion of radionuclides from medicinal plants were also estimated. The activity concentrations of 226Ra, 210Pb, 232Th, and 40K were found to vary in the range of 32.27–60.12 Bqkg−1, 56.09–160.56 Bqkg−1, 49.61–98.46 Bqkg−1, and 241.57–712.85 Bqkg−1, respectively, in the soil samples and 2.66–11.27 Bqkg−1, BDL to 87.03 Bqkg−1, 2.42–8.72 Bqkg−1, and 93.79–6831.40 Bqkg−1, respectively, in the medicinal plants corresponding to the soil samples. The activity concentration of artificially produced radionuclide 137Cs was BDL to 12.34 Bqkg−1 in the soil and it was below detectable level (BDL in all the plant samples. The soil to plant transfer factors (TF varied from 0.07 to 0.27, BDL to 0.80, 0.04 to 0.13 and 0.17 to 23.80, respectively, for 226Ra, 210Pb, 232Th, and 40K. The AACED due to the ingestion of radionuclides from the medicinal plants varied from 0.0075 to 0.1067 mSvy−1. The AACED values reported in this study are much below the world average value of 0.30 mSvy−1 for an individual. This indicates that there is no radiological health risk in using these plants for medicinal purposes. This study may also contribute data on local medicinal plants to formulate regulations related to radiological healthcare.

    International Nuclear Information System (INIS)

    The monitoring program at the Middlesex Sampling Plant (MSP) and Middlesex Municipal Landfill (MML) measures radon gas concentrations in air; external gamma radiation levels; and uranium and radium concentrations in surface water, groundwater, and sediment. To verify that the sites are in compliance with the DOE radiation protection standard (100 mrem/yr) and to assess their potential effect on public health, the radiation dose was calculated for the maximally exposed individual. Based on the conservative scenarios described in the report, this individual, at the MSP, would receive an annual external exposure approximately equivalent to 10 percent of the DOE radiation protection standard. By comparison, the incremental dose received from living in a brick house as opposed to a wooden house is about the same. At the MML, the annual external exposure to the maximally exposed individual would be less than 1 percent of the standard. The cumulative dose to the population within an 80-km (50-mi) radius of the sites that would result from radioactive materials present at the MSP and MML would be indistinguishable from the dose that the same population would receive from naturally occurring radioactive sources. Results of the 1987 monitoring show that the MSP and MML are in compliance with the DOE radiation protection standard. 14 refs., 11 figs., 22 tabs

    Greening plants are the core resources for ecological benefits and aesthetic value of urban green space. In this paper, SPAD value, or the relative chlorophyll content, was applied to urban landscape studies to improve the quantitative green evaluation of city greening plants and provide reference points. Results showed that, except for Ficus altissima and Livistona chinensis, SPAD value of different greening plants was significantly different, which changed correspondingly with tree DBH(diameter at breast height) and height in each species. DBH and leaf SPAD value showed a significant positive correlation in all species except Livistona chinensis and Syngonium podophyllum. For tall arbor tree species, SPAD value of roadside individuals was higher than those growing in park. However, for understory plants, the result was just opposite. Our study suggests that SPAD value is a good indicator to reflect plant growth conditions and growth habitat, and has great prospects for application in the urban landscape studies.%绿化植物是城市绿地实现生态效益及美学价值的核心元素。文章将SPAD叶绿素仪测定相对叶绿素含量的方法应用于城市园林绿化研究,以期为城市绿化植物的绿色定量评价研究提供参考。研究表明,不同绿化植物的SPAD值存在显著差异,除蒲葵、高山榕外,各物种SPAD值变化趋势与胸径、株高变化趋势一致。除蒲葵与白蝴蝶外,其余物种植株胸径与叶片SPAD值间存在显著正相关,叶片SPAD值随植株胸径增加而增大。高大乔木物种道路旁植株SPAD值高于公园植株;对于林下植物,结果则相反,表现为公园中植株高于道路旁。植物的SPAD值对植物生长状况及生长环境均有良好的表征,在城市园林绿化研究中有良好的应用前景。

    2015-11-01

    In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. A major cause for severe land subsidence is excessive groundwater extraction related to rapid urbanization and population growth. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs for (infra)structure. The total damage worldwide is estimated at billions of dollars annually. As subsidence is often spatially variable and can be caused by multiple processes, an assessment of subsidence in delta cities needs to answer questions such as: what are the main causes? What is the current subsidence rate and what are future scenarios (and interaction with other major environmental issues)? Where are the vulnerable areas? What are the impacts and risks? How can adverse impacts be mitigated or compensated for? Who is involved and responsible to act? In this study a quick-assessment of subsidence is performed on the following mega-cities: Jakarta, Ho Chi Minh City, Dhaka, New Orleans and Bangkok. Results of these case studies will be presented and compared, and a (generic) approach how to deal with subsidence in current and future subsidence-prone areas is provided.

    This investigation was undertaken to assess the level of environment pollution by biological monitoring. The leaves and bark of popular ornamental trees Acer pseudoplatanus L. and Acer platanoides L. and soil from the sampling sites were used to perform heavy metals pollution monitoring in urban areas with different pollution sources, as well to investigate the suitability of the leaves and bark as bioindicators of Pb, Zn, Cd and Cu pollution. Plant samples were collected at nine locations classified into three pollution groups based on metal content in the soils. The chosen pollution indices were used to assess the level of contamination according to background values. Soils in the Katowice area are found to be relatively heavily contaminated with Pb, Zn and Cd. Both of the maple tree species did not statistically differ in terms of the investigated elements' concentration in leaves or bark. Only bark samples reflected the pollution level, showing differences between the sampling points, and therefore are recommended for biomonitoring purposes.

    Experiments were carried out and chemical aspects of ambient precipitation were determined using a sequential precipitation collector for the period July 1976 through September 1977. A related report provides experimental details. In experiments with plants, experiments were aimed to document: the foliar response of six clones of hybrid poplar to simulated acid rain; effects of buffered solutions and various anions on vegetative and sexual development of gametophytes of the fern (Pteridium aquilinum) and the acid-sensitive steps of symbiotic nitrogen fixation of the garden pea (Pisum sativum). After five 6 min daily exposures to simulated rain of pH 2.7, up to 10 percent of the leaf area of some poplar clones was injured. Lesions developed mostly near stomata and vascular tissue as shown with other plant species. Acidic solutions have a marked effect on sperm motility and fertilization (sexual reproduction) of bracken fern. Since sexual reproduction of ferns is very sensitive to mildly acidic conditions under laboratory conditions, experiments are planned to view the response of sexual stages of other plant species. Nodulation and symbiotic nitrogen fixation in Pisum is very sensitive to nutrient solution acidity. Specific isolates of Rhizobium bacteria are used and the medium pH can be maintained rigidly. In experiments to determine the effects of excess acidity on soil microbiological processes, the rate of denitrification may be slowed so drastically that increases of N/sub 2/O in the atmosphere may result with a subsequent reduction in soil nitrogen levels.

Traditional memorial gardens were renovated and expanded during this period, many parks and street-side green spaces were constructed, such as Memorial Temple to Military Marquise Zhuge Liang, Guihu Lake and Thatched Cottage of Du Fu; ② Breaking-constraint period from 1979 to 1989. Classical gardens destroyed during the Great Cultural Revolution were repaired and expanded, green space planning was first compiled, garden styles combining local and modem features were explored, such as botanic garden, amusement park, Taizishan Park and Baihuatan Park; ③ Rejuvenation period from 1989 to 1999. The city loop green belts along Funan River was formed, and the new edition of Green Space System Planning of Chengdu City was finished in 1996, representative works were Shudu Avenue, City Loop Park of Funan River, Xinhua Park, Huoshui Park and so on; ④ The new beginning of this old undertaking since 2000. Relatively mature green space planning concepts were formed by considering the balanced urban-rural development with "building garden city" as the target, representative works of this period were Huanhuaxi Park, Shahe Zonal Park, Sanshenghuaxiang, Beihu Forest Park, Intangible Heritage Park, Jinsha Ruins Park, Donghu Park, green belts along the Third Ring Road, road landscapes along the South Renmin Road. Characteristics of plant landscapes in Chengdu were discussed from 2 perspectives: natural characteristics and cultural characteristics. Plant landscaping in 4 types of land uses was analyzed; park green spaces, green spaces in residential areas, road green spaces, green spaces in scenic areas; corresponding suggestions were given for the construction, and it was stressed that exploring local natural and cultural characteristics was the demand of times and the development direction of this industry.%回顾了成都园林植物造景

  13. Energy Savings Calculations for Heat Island Reduction Strategies in Baton Rouge, Sacramento and Salt Lake City

    Energy Technology Data Exchange (ETDEWEB)

    Konopacki, S.; Akbari, H.

    2000-03-01

    In 1997, the US Environmental Protection Agency (EPA) established the ''Heat Island Reduction Initiative'', to quantify the potential benefits of Heat Island Reduction (HIR) strategies (i.e., shade trees, reflective roofs, reflective pavements and urban vegetation) to reduce cooling energy use in buildings, lower the ambient air temperature and improve urban air quality in cities, and reduce CO2 emissions from power plants. Under this initiative, the Urban Heat Island Pilot Project (UHIPP) was created with the objective to investigate the potential of HIR strategies in residential and commercial buildings in three initial UHIPP cities: Baton Rouge, Sacramento and Salt Lake City. This paper summarizes our efforts to calculate the annual energy savings, peak power avoidance and annual C02 reduction of HIR strategies in the three initial cities. In this analysis, we focused on three building types that offer most savings potential: single-family residence, office and retail store. Each building type was characterized in detail by old or new construction and with a gas furnace or an electric heat pump. We defined prototypical building characteristics for each building type and simulated the impact of HIR strategies on building cooling and heating energy use and peak power demand using the DOE-2.IE model. Our simulations included the impact of (1) strategically-placed shade trees near buildings [direct effect], (2) use of high-albedo roofing material on building [direct effect], (3) combined strategies I and 2 [direct effect], (4) urban reforestation with high-albedo pavements and building surfaces [indirect effect] and (5) combined strategies 1, 2 and 4 [direct and indirect effects]. We then estimated the total roof area of air-conditioned buildings in each city using readily obtainable data to calculate the metropolitan-wide impact of HIR strategies. The results show, that in Baton Rouge, potential annual energy savings of $15M could be realized by

    Full Text Available Papaver rhoeas, an annual plant species in the Papaveraceae family, is part of the biodiversity of agricultural ecosystems and also a noxious agronomic weed. We developed microsatellite markers to study the genetic diversity of P. rhoeas, using an enriched microsatellite library coupled with 454 next-generation sequencing. A total of 13,825 sequences were obtained that yielded 1795 microsatellite loci. After discarding loci with less than six repeats of the microsatellite motif, automated primer design was successful for 598 loci. We tested 74 of these loci for amplification with a total of 97 primer pairs. Thirty loci passed our tests and were subsequently tested for polymorphism using 384 P. rhoeas plants originating from 12 populations from France. Of the 30 loci, 11 showed reliable polymorphism not affected by the presence of null alleles. The number of alleles and the expected heterozygosity ranged from 3 to 7.4 and from 0.27 to 0.73, respectively. A low but significant genetic differentiation among populations was observed (FST = 0.04; p < 0.001. The 11 validated polymorphic microsatellite markers developed in this work will be useful in studies of genetic diversity and population structure of P. rhoeas, assisting in designing management strategies for the control or the conservation of this species.

    2007-01-01

    In 2005, the U.S. Geological Survey and the City of Longmont, Colo., began a study to document chemical characteristics of St. Vrain Creek that had previously been unavailable either due to high cost of analysis or lack of analytical capability. Stream samples were collected at seven sites on St. Vrain Creek during the spring of 2005 and 2006 for analysis of wastewater compounds. A Lagrangian-sampling design was followed during each sampling event, and time-of-travel studies were conducted just prior to each sampling event to determine appropriate sampling times for the synoptic. In addition, semipermeable membrane devices, passive samplers that concentrate hydrophobic organic chemicals, were installed at six sites during the spring of 2005 and 2006 for approximately 4 weeks. After retrieval, contaminant residues concentrated in the semipermeable membrane devices were recovered and used in a toxicity assay that provided a screen for aryl hydrocarbon receptor type compounds, including polycyclic aromatic hydrocarbons, polychlorinated biphenyls, dioxins, and furans. In addition, the U.S. Geological Survey summarized information on macroinvertebrate and fish communities known from St. Vrain Creek dating back to the early 1900s in order to assess their utility in evaluating wastewater-treatment plant upgrades and habitat improvement projects. Unfortunately, because of inconsistencies in data collection these data cannot be used as intended; however, they are useful for understanding to some degree gross patterns in fish species distribution, but less so for macroinvertebrates.

    Although precipitation is correlated with fire size in desert ecosystems and is typically used as an indirect surrogate for fine fuel load, a direct link between fine fuel biomass and fire size has not been established. In addition, nitrogen (N) deposition can affect fire risk through its fertilisation effect on fine fuel production. In this study, we examine the relationships between fire size and precipitation, N deposition and biomass with emphasis on identifying biomass and N deposition thresholds associated with fire spreading across the landscape. We used a 28-year fire record of 582 burns from low-elevation desert scrub to evaluate the relationship of precipitation, N deposition and biomass with the distribution of fire sizes using quantile regression. We found that models using annual biomass have similar predictive ability to those using precipitation and N deposition at the lower to intermediate portions of the fire size distribution. No distinct biomass threshold was found, although within the 99th percentile of the distribution fire size increased with greater than 125 g m–2 of winter fine fuel production. The study did not produce an N deposition threshold, but did validate the value of 125 g m–2 of fine fuel for spread of fires.

    This paper demonstrates that rising crime rates in cities are correlated with city depopulation. Instrumental variables estimates, using measures of the certainty and severity of a state?s criminal justice system as instruments for city crime rates, imply that the direction of causality runs from crime to urban flight. Using annual city-level panel data, our estimates suggest that each additional reported crime is associated with a one person decline in city residents. There is some evidence ...

    The plant was in operation for the equivalent of 247 days, an on-stream factor of 67.7%. Kentucky 9 coals from the Lafayette, Dotiki and Fies mines were processed. During 1980, the operating conditions and equipment were adjusted to evaluate potential process improvements. These experiments produced significant results in the following areas: Operating V103 High Pressure Separator in the hot mode; varying T102 Vacuum Column operating temperature; adding light SRC (LSRC), a product of the third stage of the Critical Solvent Deashing (CSD) unit, to the process solvent; investigating the effects of the chlorine content of the feed coal on corrosion in the process vessels; evaluating the effects of adding sodium carbonate on corrosion rates; operating under conditions of low severity; i.e., low reactor temperature and long residence time; and testing an alternate CSD deashing solvent. A series of simulation runs investigating the design operating conditions for a planned 6000 ton per day SRC-I demonstation plant were also completed. Numerous improvements were made in the CSD processing area, and the components for a hydrotreating unit were installed.

    The cooling system of the Ringhals nuclear power plant affects the fish community in two steps. In the first step, seawater is used to cool the system in the nuclear power plant. Fish eggs, larvae and small juveniles are carried by the incoming water and are exposed to risk of damage or mortality. In the second step the heated water is released back into the sea, where the fish is affected by the increase in temperature. Reactor 1 and reactor 3 at Ringhals nuclear power plant produced electricity during the major part of the year 2011, with exceptions for the annual audits, and shorter stops in production. Reactor 2 only operated between January and April, due to a fire which led to a shutdown and a thorough remediation work during the rest of the year. Reactor 4 was producing electricity from January to June, but was later shutdown due to a prolonged annual audit until November. Fish eggs and fish larvae are sampled in the incoming cooling water using a modified Bongo net to monitor losses of eggs and larvae in the nuclear power plant. The abundance of shorthorn sculpin larvae (Myoxocephalus scorpius) has decreased since the sampling period started, although it is still the most abundant larvae. Also the abundance of rock gunnel larvae (Pholis gunnellus) has decreased over the years. To sample juvenile fish a modified Isaacs-Kidd midwater-trawl is used. This sampling is mainly focused on glass eels (Anguilla anguilla). The abundance of glass eels have declined strongly since the beginning of the 1980's, but a minor increase was observed in 2011. The decline of the glass eel abundance is most probably due to a general decrease in recruitment and not to a local effect caused by the nuclear power plant. The effects of the heated water released into the sea are monitored by fykenet surveys in the recipient as well as in a reference area. These two areas are monitored in two seasons to compare differences between the two areas in naturally cold and warm water of

    Waste form dissolution studies and preliminary performance analyses were carried out to contribute a part of the data needed for the selection of a waste form for the disposal of Savannah River Plant defense waste in a deep geologic repository. The first portion of this work provides descriptions of the chemical interactions between the waste form and the geologic environment. We reviewed critically the dissolution/leaching data for borosilicate glass and SYNROC. Both chemical kinetic and thermodynamic models were developed to describe the dissolution process of these candidate waste forms so as to establish a fundamental basis for interpretation of experimental data and to provide directions for future experiments. The complementary second portion of this work is an assessment of the impacts of alternate waste forms upon the consequences of disposal in various proposed geological media. Employing systems analysis methodology, we began to evaluate the performance of a generic waste form for the case of a high risk scenario for a bedded salt repository. Results of sensitivity analysis, uncertainty analyses, and sensitivity to uncertainty analysis are presented.

  16. Simulated annual changes in plant functional types and their responses to climate change on the northern Tibetan Plateau

    Changes in plant functional types (PFTs) have important implications for both climate and water resources. Still, little is known about whether and how PFTs have changed over the past decades on the northern Tibetan Plateau (NTP) where several of the top largest rivers in the world are originated. Also, the relative importance of atmospheric conditions vs. soil physical conditions in affecting PFTs is unknown on the NTP. In this study, we used the improved Lund-Potsdam-Jena Dynamic Global Vegetation Model to investigate PFT changes through examining the changes in foliar projective coverages (FPCs) during 1957-2009 and their responses to changes in root zone soil temperature, soil moisture, air temperature, precipitation and CO2 concentrations. The results show spatially heterogeneous changes in FPCs across the NTP during 1957-2009, with 34 % (13 %) of the region showing increasing (decreasing) trends. Dominant drivers responsible for the observed FPC changes vary with regions and vegetation types, but overall, precipitation is the major factor in determining FPC changes on the NTP with positive impacts. Soil temperature increase exhibits small but negative impacts on FPCs. Different responses of individual FPCs to regionally varying climate change result in spatially heterogeneous patterns of vegetation changes on the NTP. The implication of the study is that fresh water resources in one of the world's largest and most important headwater basins and the onset and intensity of Asian monsoon circulations could be affected because of the changes in FPCs on the NTP.

    2012-12-01

    A prerequisite to an air quality management plan for a city is some idea of the main sources of pollution and their contributions for a city. This paper presents the results of an application of the SIM-air modeling tool in six Indian cities - Pune, Chennai, Indore, Ahmedabad, Surat, and Rajkot. Using existing and publicly available data, we put together a baseline of multi-pollutant emissions for each of the cities and then calculate concentrations, health impacts, and model alternative scenarios for 2020. The measured annual PM10 (particulate matter with aerodynamic diameter less than 10 micron meter) concentrations in μg m-3 averaged 94.7 ± 45.4 in Pune, 73.1 ± 33.7 in Chennai, 118.8 ± 44.3 in Indore, 94.0 ± 20.4 in Ahmedabad, 89.4 ± 12.1 in Surat, and 105.0 ± 25.6 in Rajkot, all exceeding the annual standard of 60 μg m-3. The PM10 inventory in tons/year for the year 2010 of 38,400 in Pune, 50,200 in Chennai, 18,600 in Indore, 31,900 in Ahmedabad, 20,000 in Surat, and 14,000 in Rajkot, is further spatially segregated into 1 km grids and includes all known sources such as transport, road dust, residential, power plants, industries (including the brick kilns), waste burning, and diesel generator sets. We use the ATMoS chemical transport model to validate the emissions inventory and estimate an annual premature mortality due to particulate pollution of 15,200 for the year 2010 for the six cities. Of the estimated 21,400 premature deaths in the six cities in 2020, we estimate that implementation of the six interventions in the transport and brick kiln sectors, can potentially save 5870 lives (27%) annually and result in an annual reduction of 16.8 million tons of carbon dioxide emissions in the six cities.

    Studies conducted by the Missouri Department of Conservation in the late 1980s found high levels of PCBs and chlordane in fish from the Blue River near the Kansas City Plant (KCP). Follow-on biomonitoring studies by Oak Ridge National Laboratory (ORNL) staff from 1991-1993 (Southworth et al. 1992, Ashwood et al. 1993, Ashwood and Peterson 1994), and again on a more limited basis in 1998 (Ashwood 1998), were conducted for the KCP. The studies in the early 1990s characterized concentrations of PCBs and chlordane in fish from Indian Creek, Boone Creek, and the Blue River. These studies concluded that the KCP appears to be one of multiple sources of PCBs to both Indian Creek and the Blue River. There continues to be interest in the potential role of KCP discharges on PCB concentrations in local fish. Elevated PCB concentrations in Indian Creek fish have consistently been found at the location downstream of the NPDES-permitted 002 discharge, which drains a section of the KCP complex. A risk evaluation conducted during 2001 found that some local fish exceeded risk-based guidelines for PCBs. It has been nearly a decade since intensive sampling of fish was conducted within all waters near the KCP (the 1998 study included Indian Creek only); therefore, an update study was warranted. The purpose of the present study is to provide PCB and chlordane concentrations in fish useful in determining the potential human health risks associated with fish in waters near the KCP, to evaluate the relative significance of KCP discharges relative to other inputs on fish levels, and to determine if levels have changed in the years since fish were last analyzed. Fish were collected near the KCP for PCB and chlordane analyses in October and November of 2002. Although chlordane does not appear to be associated with the KCP (it was most commonly used to treat household termite infestations until 1988), it is of interest from an overall risk standpoint. Because monitoring change over time is an

    Many studies have addressed evolution and phylogeography of plant taxa in oceanic islands, but have primarily focused on endemics because of the assumption that in widespread taxa the absence of morphological differentiation between island and mainland populations is due to recent colonization. In this paper, we studied the phylogeography of Scrophularia arguta, a widespread annual species, in an attempt to determine the number and spatiotemporal origins of dispersal events to Canary Islands. Four different regions, ITS and ETS from nDNA and psbA-trnH and psbJ-petA from cpDNA, were used to date divergence events within S. arguta lineages and determine the phylogenetic relationships among populations. A haplotype network was obtained to elucidate the phylogenetic relationships among haplotypes. Our results support an ancient origin of S. arguta (Miocene) with expansion and genetic differentiation in the Pliocene coinciding with the aridification of northern Africa and the formation of the Mediterranean climate. Indeed, results indicate for Canary Islands three different events of colonization, including two ancient events that probably happened in the Pliocene and have originated the genetically most divergent populations into this species and, interestingly, a recent third event of colonization of Gran Canaria from mainland instead from the closest islands (Tenerife or Fuerteventura). In spite of the great genetic divergence among populations, it has not implied any morphological variation. Our work highlights the importance of nonendemic species to the genetic richness and conservation of island flora and the significance of the island populations of widespread taxa in the global biodiversity.

    2015-01-01

    Full Text Available Accurate forecast of municipal water production is critically important for arid and oil rich countries such as Saudi Arabia which depend on costly desalination plants to satisfy the growing water demand. Achieving the desired prediction accuracy is a challenging task since the forecast model should take into consideration a variety of factors such as economic development, climate conditions and population growth. The task is further complicated given that Mecca city is visited regularly by large numbers during specific months in the year due to religious reasons. This study develops a neural network model for forecasting the monthly and annual water demand for Mecca city, Saudi Arabia. The proposed model used historic records of water production and estimated visitors’ distribution to calibrate a neural network model for water demand forecast. The explanatory variables included annually-varying variables such as household income, persons per household, and city population, along with monthly-varying variables such as expected number of visitors each month and maximum monthly temperature. The NN prediction outperforms that of a regular econometric model. The latter is adjusted such that it can provide monthly and annual predictions.

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available With most eastern Chinese cities facing major air quality challenges, there is a strong need for city-scale emission inventories for use in both chemical transport modeling and the development of pollution control policies. In this paper, a high-resolution emission inventory of air pollutants and CO2 for Nanjing, a typical large city in the Yangtze River Delta, is developed incorporating the best available information on local sources. Emission factors and activity data at the unit or facility level are collected and compiled using a thorough onsite survey of major sources. Over 900 individual plants, which account for 97 % of the city's total coal consumption, are identified as point sources, and all of the emission-related parameters including combustion technology, fuel quality, and removal efficiency of air pollution control devices (APCD are analyzed. New data-collection approaches including continuous emission monitoring systems and real-time monitoring of traffic flows are employed to improve spatiotemporal distribution of emissions. Despite fast growth of energy consumption between 2010 and 2012, relatively small inter-annual changes in emissions are found for most air pollutants during this period, attributed mainly to benefits of growing APCD deployment and the comparatively strong and improving regulatory oversight of the large point sources that dominate the levels and spatial distributions of Nanjing emissions overall. The improvement of this city-level emission inventory is indicated by comparisons with observations and other inventories at larger spatial scale. Relatively good spatial correlations are found for SO2, NOx, and CO between the city-scale emission estimates and concentrations at 9 state-opertated monitoring sites (R = 0.58, 0.46, and 0.61, respectively. The emission ratios of specific pollutants including BC to CO, OC to EC, and CO2 to CO compare well to top-down constraints from ground observations. The inter-annual

    In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs. This effects roads and transportation networks, hydraulic infrastructure - such as river embankments, sluice gates, flood barriers and pumping stations -, sewage systems, buildings and foundations. The total damage worldwide is estimated at billions of dollars annually. Excessive groundwater extraction after rapid urbanization and population growth is the main cause of severe land subsidence. In addition, coastal cities are often faced with larger natural subsidence, as they are built on thick sequences of soft soil. Because of ongoing urbanization and population growth in delta areas, in particular in coastal megacities, there is, and will be, more economic development in subsidence-prone areas. The impacts of subsidence are further exacerbated by extreme weather events (short term) and rising sea levels (long term).Consequently, detrimental impacts will increase in the near future, making it necessary to address subsidence related problems now. Subsidence is an issue that involves many policy fields, complex technical aspects and governance embedment. There is a need for an integrated approach in order to manage subsidence and to develop appropriate strategies and measures that are effective and efficient on both the short and long term. Urban (ground)water management, adaptive flood risk management and related spatial planning strategies are just examples of the options available. A major rethink is needed to deal with the 'hidden' but urgent

  2. The annual invasive plant, Impatiens glandulifera (Himalayan Balsam) as a trigger for high-magnitude soil erosion in temperate river systems

    Science.gov (United States)

    Greenwood, Philip; Kuhn, Nikolaus

    2015-04-01

    The invasive plant, Impatiens glandulifera (common English name: Himalayan Balsam), is now found in most temperate European countries, as well as across large parts of North America and on some Australasian islands. As a ruderal species, it favours damp, fertile soils that experience frequent disturbance. Riverbanks and the riparian zone thus represent prime habitat. Its ability to out-compete most perennial vegetation yet tendency to suddenly die during seasonally cold weather has led to claims that it may promote soil erosion, particularly along inland watercourses. Despite the strong implication, this was only recently proven during an investigation conducted over one dieback and regrowth cycle in 2012/13 along a watercourse in northwest Switzerland. Here we reinterpret those initial findings and also present additional data from the same watercourse which now covers three die-off and regrowth cycles, as well as data over two die-off and regrowth cycles from a river system in southwest UK. Results from all monitoring campaigns strongly support the original conclusion that I. glandulifera promotes significant soil erosion along contaminated sections of riverbank and riparian zone. More specifically, however, approximately one third of the total number of contaminated locations monitored (n=41) recorded net ground surface retreat that exceeded, by at least one order of magnitude, equivalent annual erosion rates documented on cultivated hillslopes in temperate regions. Not only does I. glandulifera induce repeat cycles of colonization and die-off, therefore, but collectively, the results generated so far strongly infer that under certain circumstances, this cycle of events can commonly trigger severe or even extreme erosion. Seasonally induced soil loss of this magnitude, particularly along short sections of watercourses, is unsustainable in the long-term and may lead to key fluvial features undergoing profound morphological and structural changes. Such an effect

    This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

  17. Evapotranspiration Within the Groundwater Model Domain of the Tuba City, Arizona, Disposal Site Interim Report

    Energy Technology Data Exchange (ETDEWEB)

    None, None

    2015-03-01

    The revised groundwater model includes estimates of evapotranspiration (ET). The types of vegetation and the influences of ET on groundwater hydrology vary within the model domain. Some plant species within the model domain, classified as phreatophytes, survive by extracting groundwater. ET within these plant communities can result in a net discharge of groundwater if ET exceeds precipitation. Other upland desert plants within the model domain survive on meteoric water, potentially limiting groundwater recharge if ET is equivalent to precipitation. For all plant communities within the model domain, excessive livestock grazing or other disturbances can tip the balance to a net groundwater recharge. This task characterized and mapped vegetation within the groundwater model domain at the Tuba City, Arizona, Site, and then applied a remote sensing algorithm to estimate ET for each vegetation type. The task was designed to address five objectives: 1. Characterize and delineate different vegetation or ET zones within the groundwater model domain, focusing on the separation of plant communities with phreatophytes that survive by tapping groundwater and upland plant communities that are dependent on precipitation. 2. Refine a remote sensing method, developed to estimate ET at the Monument Valley site, for application at the Tuba City site. 3. Estimate recent seasonal and annual ET for all vegetation zones, separating phreatophytic and upland plant communities within the Tuba City groundwater model domain. 4. For selected vegetation zones, estimate ET that might be achieved given a scenario of limited livestock grazing. 5. Analyze uncertainty of ET estimates for each vegetation zone and for the entire groundwater model domain.

    2015-10-31

    Brigham City owns and operates its own municipal power system which currently includes several hydroelectric facilities. This project was to update the efficiency and capacity of current hydro production due to increased water flow demands that could pass through existing generation facilities. During 2006-2012, this project completed efficiency evaluation as it related to its main objective by completing a feasibility study, undergoing necessary City Council approvals and required federal environmental reviews. As a result of Phase 1 of the project, a feasibility study was conducted to determine feasibility of hydro and solar portions of the original proposal. The results indicated that the existing Hydro plant which was constructed in the 1960’s was running at approximately 77% efficiency or less. Brigham City proposes that the efficiency calculations be refined to determine the economic feasibility of improving or replacing the existing equipment with new high efficiency equipment design specifically for the site. Brigham City completed the Feasibility Assessment of this project, and determined that the Upper Hydro that supplies the main culinary water to the city was feasible to continue with. Brigham City Council provided their approval of feasibility assessment’s results. The Upper Hydro Project include removal of the existing powerhouse equipment and controls and demolition of a section of concrete encased penstock, replacement of penstock just upstream of the turbine inlet, turbine bypass, turbine shut-off and bypass valves, turbine and generator package, control equipment, assembly, start-up, commissioning, Supervisory Control And Data Acquisition (SCADA), and the replacement of a section of conductors to the step-up transformer. Brigham City increased the existing 575 KW turbine and generator with an 825 KW turbine and generator. Following the results of the feasibility assessment Brigham City pursued required environmental reviews with the DOE and

    This report describes the searches for dead birds in the Smoela wind-power plant area (SWPPA) in 2011, and compares the results of the dead birds found with 2006-2010.The search effort in 2006-2010 was systematic, as the same method and procedures were followed, with the same effort each week throughout each year. The results of dead birds found could thus be compared between years, seasons, months, and the different parts of the wind-power plant and single turbines. The data could be used to calculate averages found each year, and also now making it possible to estimate total numbers annually colliding with turbines for several species. These data are therefore a good basis for comparing result for later years. To search for dead birds, localize and recording wind turbine victims are the first steps towards estimating real collision numbers in a wind-power plant area. In addition, there are several bi-ases affecting the proportion of dead birds available for searches. Several methods may be used, among them different approaches using dogs. In the SWPPA a feather search dog was used, to search, find and indicate feathers and other remains from dead birds. In 2006-2010 two dogs were used in SWPPA, both with god search qualities. In 2011 the best of these dogs, the giant schnauzer Luna, was used on all turbine searches. The search motivation of Luna has been very good in nearly all searches in 2011. The search results from SWPPA therefore are as reliable as possible today. In 2011 searches were carried out at all turbines five times, three in spring (5-7 April, 29 April to 1 May, 26-28 May) and two in autumn (12-15 September, 21-22 November). In April to May a total of 203 turbine searches were performed. In each of the previous years, the total numbers of turbine searches in the spring (March - 15 June) varied between 359 and 473. In autumn 2011 a total of 136 turbine searches were performed, about 60 % of each of the previous years in the months September

    The Conference on Plant-Made Pharmaceuticals was an inaugural event organized by Molecular Farming Association Inc, a non-profit organization created in 2000 to support the emergence of plant-made biopharmaceuticals and plant-factory companies. The meeting was sponsored by the Government of Canada, the Gouvermement du Québec and the Société Générale de Financement, along with 20 companies involved in plant-made pharmaceuticals and related activities. Although there was very little discussion of new biopharmaceuticals under development with these systems, this was the first meeting where participants could survey the entire breadth of technologies and approaches that are being taken to produce biopharmaceuticals in transgenic plants. Participants also heard about the technical, manufacturing and regulatory issues confronting transgenic plant expression systems, as well as from 'new technology' companies that hav not previously presented in a public forum. There was a clear sense emerging from the meeting that the hurdles currently facing the industry will be overcome and that transgenic plant systems will eventually move into the mainstream of biopharmaceutical manufacturing technologies.

    With the aggravation of traffic jam traditional logistics network has reached high-point in big cities in China, so the logistics system on the ground will gradually transfer to underground on various layers in the future so as to release the ground space in cities. Based on SMT theory, this paper establishes underground tree logistics network layout model. Because SMT is NP-complete problem, the algorithm optimization capability is the key of research. Plant growth simulation algorithm (PGSA) in this paper is an intelligence optimization algorithm, which takes plant phototropism growth pattern as its heuristic criterion. Through artificial plant growth process in solution space of given logistics node set, we can get the optimal layout of underground logistics network in cities. Through the calculation of STEINLIB lab data announced internationally, PGSA is demonstrated with better accuracy, stability and global searching ability, by comparing the solutions of ant algorithm and simulated annealing algorithm.%交通拥堵问题的加剧使传统物流网络在我国大型城市已达到极限,未来地面物流系统将逐步向地下不同层次里转移并释放出城市地上空间.本文以斯坦纳最小树(SMT)为理论模型,建立了符合我国大型城市不断扩展这一特点的树状地下物流网络布局模型.由于SMT为NP-完全问题,因此算法的寻优能力是研究的关键.本文所采用的模拟植物生长算法(PGSA)是以植物向光性理论为启发式准则的智能算法,该算法是利用人工植物在给定物流节点集解空间中的生长过程得到城市地下物流网络的最优布局.通过对国际公布的STEINLIB实例数据计算并与蚁群算法和模拟退火算法进行比较,表明模拟植物生长算法具有较强的精确性、稳定性和全局搜索能力.

    137Cs concentrations in ten species of foliose lichens collected within Tsukuba-city in August 2013 ranged from 1.7 to 35 kBq/kg. The relationships between 137Cs in two dominant species, Dirinaria applanata and Physcia orientalis, and the air dose rate (μSv/h) at the sampling sites were investigated. 137Cs in P. orientalis measured about 1 year after the Fukushima nuclear accident was correlated (r2 = 0.80) more closely with the air dose rate than those measured after about 2 years (r2 = 0.65), possibly demonstrating its continued value as a biomonitor to reflect ambient fall-out levels. In contrast, those of Dirinaria applanata were not correlated with the air dose rate in either year. - Highlights: • We report 137Cs concentrations of ten foliose lichens in Tsukuba-city, Japan. • 137Cs of Physcia orientalis correlated with the air dose rate at the sampling sites. • Physcia orientalis is invaluable for monitoring the radioactive fallout

  17. Sensors, motes, and smart dust : WirelessHART sensors are finding application in gas plants, well rigs and soon may be embraced by entire cities

    Energy Technology Data Exchange (ETDEWEB)

    Chandler, G.

    2009-05-15

    The WirelessHART (Highway Addressable Remote Transducer) is wireless communication system designed to address the needs of the process industry. The sensor system can be used in applications that were previously not practical or possible, such as in drilling rigs and gas plants. The wireless aspect is an important new innovation that delivers key economic benefits. For some temperature measurements in industrial plants, it is not always feasible to run wires all the way up the stack. The wireless solution consists of wireless gateways and field devices that receive and condition data from sensors that measure temperatures, pressures, flow rates, vibration, and other process parameters. The same devices also relay the measurement data to the gateway. Up to 100 devices can be linked wirelessly to a gateway, which passes on the process information to the control system of the plant, drilling rig, or other industrial facility. Multiple networks can be bridged using Wi-Fi. Once deployed, the technology optimizes itself. The system is also useful for determining temperatures and pressures on the mud tanks at drilling rigs and blowout preventers. The system is being used in highly automated and multi-process plants like refineries and upgraders where numerous sensors are needed. Savings on the wireless installations allow a company to afford the installation of more sensors in places they previously could not cost-effectively deploy wired sensors, thereby resulting in improved productivity, safety, and reduced plant downtimes. Talisman Energy's Teepee Creek sour gas plant near Grande Prairie Alberta uses the WirelessHART network to measure temperatures, pressure, differential pressure, tank levels, and valve positions. 4 figs.

  18. Branding Cities, Changing Societies

    DEFF Research Database (Denmark)

    Ooi, Can-Seng

    Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

    Robertson, A.; Domeracki, W.; Newby, R.; Rehmat, A.; Horazak, D.

    1992-10-01

    After many years of experimental testing and development work, coal-fired pressurized fluidized bed (PFB) combustion combined-cycle power plants are moving toward reality. Under the US Department of Energy`s Clean Coal Technology Program, a 70-MWe PFB combustion retrofit, utilizing a 1525{degrees}F gas turbine inlet temperature, has been built and operated as a demonstration plant at the American Electric Power Company`s Tidd Plant in Brilliant, Ohio. As PFB combustion technology moves closer and closer to commercialization, interest is turning toward the development of an even more efficient and more cost-effective PFB combustion plant. The targeted goals of this ``second-generation`` plant are a 45-percent efficiency and a cost of electricity (COE) that is at least 20 percent lower than the COE of a conventional pulverized-coal (PC)-fired plant with stack gas scrubbing. In addition, plant emissions should be within New Source Performance Standards (NSPS) and the plant should have high availability, be able to burn different ranks of coal, and incorporate modular construction technologies. In response to this need, a team of companies led by Foster Wheeler Development Corporation (FWDC). The key components in the proposed second-generation plant are the carbonizer, CPFBC, ceramic cross-flow filter, and topping combustor. Unfortunately, none of these components has been operated at proposed plant operating conditions, and experimental tests must be conducted to explore/determine their performance throughout the proposed plant operating envelope. The major thrust of Phase 2 is to design, construct, test, and evaluate the performance of the key components of the proposed plant.

This possibility has been examined by comparing the emissions of five major atmospheric pollutants, i.e., particulates, sulfur oxides, carbon monoxide, hydrocarbons, and nitrogen oxides, from the existing heating and electric system in the City of Boston with those from a proposed district heating system. Detailed, spatial distribution of existing heating load and fuel mix is developed to specify emissions associated with existing heating systems. Actual electric-power-plant parameters and generation for the base year are specified. Additional plant fuel consumption and emissions resulting from cogeneration operation have been estimated. Six alternative fuel-emissions-control scenarios are considered. The average annual ground-level concentrations of sulfur oxides are calculated using a modified form of the EPA's Climatological Dispersion Model. This report describes the methodology, the results and their implications, and the areas for extended investigation. The initial results confirm expectations. Average sulfur oxides concentrations at various points within and near the city drop by up to 85% in the existing fuels scenarios and by 95% in scenarios in which different fuels and more-stringent emissions controls at the plants are used. These reductions are relative to concentrations caused by fuel combustion for heating and large commercial and industrial process uses within the city and Boston Edison Co. electric generation.

    The objective of this research is to explore the feasibility of producing engineered fuels from a combination of renewable and non renewable energy sources. The components are flyash (containing coal fines) and locally available biomass waste. The constraints were such that no other binder additives were to be added. Listed below are the main accomplishments of the project: (1) Determination of the carbon content of the flyash sample from the Aquila plant. It was found to be around 43%. (2) Experiments were carried out using a model which simulates the press process of a wood pellet machine, i.e. a bench press machine with a close chamber, to find out the ideal ratio of wood and fly ash to be mixed to get the desired briquette. The ideal ratio was found to have 60% wood and 40% flyash. (3) The moisture content required to produce the briquettes was found to be anything below 5.8%. (4) The most suitable pressure required to extract the lignin form the wood and cause the binding of the mixture was determined to be 3000psi. At this pressure, the briquettes withstood an average of 150psi on its lateral side. (5) An energy content analysis was performed and the BTU content was determined to be approximately 8912 BTU/lb. (6) The environmental analysis was carried out and no abnormalities were noted. (7) Industrial visits were made to pellet manufacturing plants to investigate the most suitable manufacturing process for the briquettes. (8) A simulation model of extrusion process was developed to explore the possibility of using a cattle feed plant operating on extrusion process to produce briquettes. (9) Attempt to produce 2 tons of briquettes was not successful. The research team conducted a trial production run at a Feed Mill in La Junta, CO to produce two (2) tons of briquettes using the extrusion process in place. The goal was to, immediately after producing the briquettes; send them through Aquila's current system to test the ability of the briquettes to flow

  5. Sustainable Cities

    Georg, Susse; Garza de Linde, Gabriela Lucía

    Judging from the number of communities and cities striving or claiming to be sustainable and how often eco-development is invoked as the means for urban regeneration, it appears that sustainable and eco-development have become “the leading paradigm within urban development” (Whitehead 2003......). But what is it that is driving these urban transformations? Clearly, there are many probable answers to this complex question and in what follows we will focus on one particular catalyst of change – urban design competitions. Considered as field changing events (Lampel and Meyer 2008, Anand and Jones 2008......), urban design competitions are understudied mechanisms for bringing about field level changes. Drawing on actor network theory, this paper examines how urban design competitions may bring about changes within the professional field through the use of intermediaries such as a sustainable planning...

    Ageing management is not a simple process. The NRC has been involved with its ageing management and licence renewal programmes since 1982. At that time, the NRC began its Ageing Research Program. In 1991, it initiated a License Renewal Rule and Demonstration Program. In the course of these activities, it was discovered that the NRC was giving insufficient credit for the existing PLiM programme. In 1995, there was an Amended License Renewal rule, which focused on managing the adverse effects of ageing. In 1998, the NRC received its first licence renewal application to enable a plant to operate from 40 to 60 years. Presently (May 2012), the NRC has renewed licences for 71 plants at 42 sites. Ten units at nine sites have passed 40 years of licensed operation and entered the period of 40−60 year extended operation. There are applications under review for 15 units at 11 sites. The NRC expects applications for all remaining currently operating units. The NRC’s licence renewal guiding principles are that the ongoing regulatory process is adequate to ensure the safety of all currently operating US plants and that the same plant operating rules apply during the 20-year renewal term. In addition, the NRC applies supplementary conditions for ageing management through the licence renewal process and is fully aware that operating experience is very important in terms of lessons learned, which can then bring about further changes in the process and in practice. Recent additional NRC guidance addresses the need to manage buried piping and tanks, inaccessible non-environmentally qualified cables, spent fuel pool neutron absorbing materials other than Boraflex, and pressurized water reactor vessel internals. In summary, the NRC believes that: – Ageing management must be a living process that continuously incorporates operating experience. – Research is necessary to establish the technical basis for LTO of existing nuclear plants beyond 60 years. – The industry must have a

    After the Great East Japan Earthquake on 11 March 2011, the environmental radiation dose in Fukushima City increased. On 11 April, 1 mo after the earthquake, the environmental radiation dose rate at various surfaces in the same area differed greatly by surface property. Environmental radiation measurements continue in order to determine the estimated time to 50% reduction in environmental radiation dose rates by surface property in order to make suggestions for decontamination in Fukushima. The measurements were carried out from 11 April to 11 November 2011. Forty-eight (48) measurement points were selected, including four kinds of ground surface properties: grass (13), soil (5), artificial turf (7), and asphalt (23). Environmental radiation dose rate was measured at heights of 100 cm above the ground surface. Time to 50% reduction of environmental radiation dose rates was estimated for each ground surface property. Radiation dose rates on 11 November had decreased significantly compared with those on 11 April for all surface properties. Artificial turf showed the longest time to 50% reduction (544.32 d, standard error: 96.86), and soil showed the shortest (213.20 d, standard error: 35.88). The authors found the environmental radiation dose rate on artificial materials to have a longer 50% reduction time than that on natural materials. These results contribute to determining an order of priority for decontamination after nuclear disasters.

    Plant domestication modifies a wild species genetically for human use. Among thousands of domesticated plants, a major distinction is the difference between annual and perennial life cycles. The domestication of perennials is expected to follow different processes than annuals, with distinct genetic outcomes. Here we examine domestication from a population genetics perspective, with a focus on three issues: genetic bottlenecks during domestication, introgression as a source of local adaptation, and genetic load. These three issues have been studied nominally in major annual crops but even less extensively in perennials. Here we highlight lessons from annual plants, motivations to study these issues in perennial plants, and new approaches that may lead to further progress.

    The European perch is a species endowed with high adaptation capabilities as regards different environmental conditions. The aim of the study was to analyse the annual developmental cycle of ovaries of the European perch from the Oder river, Lake Dąbie and a drainage canal (Warm Canal) carrying post-cooling water from the Dolna Odra power plant (annual average water temperature in the canal is higher by 6-8°C than the water of the other sampling sites). Most of the female perch caught in the canal carrying post-cooling water had immature stage 2 gonads (delayed development of the gonads) and were smaller than the fish from the other sites. No traces of spawning in the form of deposed egg strings were found in the drainage canal. Adult individuals avoid high temperatures found in the Warm Canal. In April, in perch from all sites, ovaries with post-spawning oocytes were observed. The spawning season of the females lasted from the beginning of April until May. Stage 4 of gonad development, with oocytes in advanced vitellogenesis, was the longest and ranged from September through February.

The development make national boundary become not so important, the function of the city is increasingly outstanding. In other words, national competition ability is morally now on the city competition ability. At the same time, this development result that the industry is divided internationally and is divided in cities. Therefore, under the condition of globalization, if the city wants the superior development, it must take advantages and avoid shortage, to position the city accurately, establish the competition and development the strategy. The city positioning is clearly defined the city competition ability, more important it indicated the direction of the city development. Trough the analysis of the resource and environment of the city, decide an accurate position of the best function of the city, well configure the inner and outside resource, catch the opportunities,face the challenges, maximized the market share in order to maximized the wealth and city competition ability.

  1. Energy savings for heat-island reduction strategies in Chicago and Houston (including updates for Baton Rouge, Sacramento, and Salt Lake City); FINAL

    International Nuclear Information System (INIS)

    In 1997, the U.S. Environmental Protection Agency (EPA) established the ''Heat Island Reduction Initiative'' to quantify the potential benefits of Heat-Island Reduction (HIR) strategies (i.e., shade trees, reflective roofs, reflective pavements and urban vegetation) to reduce cooling-energy use in buildings, lower the ambient air temperature and improve urban air quality in cities, and reduce CO2 emissions from power plants. Under this initiative, the Urban Heat Island Pilot Project (UHIPP) was created with the objective of investigating the potential of HIR strategies in residential and commercial buildings in three initial UHIPP cities: Baton Rouge, LA; Sacramento, CA; and Salt Lake City, UT. Later two other cities, Chicago, IL and Houston, TX were added to the UHIPP. In an earlier report we summarized our efforts to calculate the annual energy savings, peak power avoidance, and annual CO2 reduction obtainable from the introduction of HIR strategies in the initial three cities. This report summarizes the results of our study for Chicago and Houston. In this analysis, we focused on three building types that offer the highest potential savings: single-family residence, office and retail store. Each building type was characterized in detail by vintage and system type (i.e., old and new building constructions, and gas and electric heat). We used the prototypical building characteristics developed earlier for each building type and simulated the impact of HIR strategies on building cooling- and heating-energy use and peak power demand using the DOE-2.1E model. Our simulations included the impact of (1) strategically-placed shade trees near buildings[direct effect], (2) use of high-albedo roofing material on the building[direct effect], (3) urban reforestation with high-albedo pavements and building surfaces[indirect effect] and (4) combined strategies 1, 2, and 3[direct and indirect effects]. We then estimated the total roof area of air-conditioned buildings in each

    Full Text Available Palynological and palaeobotanical results from three representative cores investigated in 1994—1995 in connection with the archaeological excavations in the Rettig "Palace", Turku, Finland, are discussed. The cultural layer consisted of a heterogeneous urban upper stratum and a more humid and more homogeneous lower stratum, all resting on a clay sequence several metres thick. A chronological series of marine clay, partly river-washed and redeposited clay, and clayey soil characterized by aerophilous diatoms was determined. Diatom analysis was used to reconstruct sedimentation environment and the development of the natural landscape in relation to land uplift. Pollen analysis was used to trace the transformation of the natural landscape into a cultural landscape and finally into an urban settlement area. The pollen results were complemented by those on plant macrofossils, which consisted of the remnants of 124 species of many different groups, such as natural, cultivated, imported, medical and collected plants. Phytoliths were investigated from the surface material of a grindstone found on the site, and typical morphotypes were described although no typical cereal phytoliths could be identified.

    International Nuclear Information System (INIS)

    Today, the INL’s Advanced Test Reactor is the world’s premier nuclear test reactor. And, it’s a vital tool in developing the next generation of nuclear power plants. That continues a great tradition of work at the INL having a significant influence on every commercial reactor designed in the United States and in many of your countries. One of the key points I make when I meet with a business leader looking to expand or open up a new business in Idaho is our low cost, reliable energy. We have a competitive advantage that provides enormous benefits to Idaho’s industrial, commercial and residential customers. The average residential electric bill in Idaho is 30 per cent less than the national average. The downside is that Idaho only generates about half the electricity it uses; the rest is imported primarily from coal fired plants in neighbouring states. Now, we all know that demand for energy nationwide will grow significantly in the next few decades. For Idaho and many other areas of the western USA, that means we need to increase the supply of safe, reliable and affordable power. And that in turn will require us to be more efficient and more effective, more creative and more collaborative in the role we play as policy makers, industry leaders and regulators of commercial nuclear power

    International Nuclear Information System (INIS)

    The Fukushima incident, following the earthquake and tsunami in Japan, has shaken global public confidence in the safety of nuclear power. Still, nuclear power remains and will remain important for many countries. It is important to maintain plant safety, particularly as facilities age, and since 354 of the 436 nuclear power plants in the world are equal to or greater than 20 effective years of age. In this respect, PLiM becomes increasingly important and may very well become indispensable in the future. It is important that ageing management programmes be established in accordance with guidelines issued by government regulatory and industry agencies. For example, a PLiM programme could draw on United States Nuclear Regulatory Commission (NRC) rules, guidance and reports; on industry guidance such as provided by the Nuclear Engineering Institute (NEI), by the Electric Power Research Institute (EPRI) and by the IAEA through its safety standards. The ultimate goal of this conference is to do address these main themes through an open exchange of information, by means of the keynote speeches, the oral/poster presentations and the panel discussions. If these activities are approached in this spirit, the sharing of recent lessons learned will achieve the conference’s goals and play a critical role in the development of new and effective approaches to addressing issues relating to structure, systems and component (SSC) ageing and PLiM

    This annual report describes the first year's accomplishments under the NERI2000-109 project. We present a model-independent approach to quantify changes in the nonlinear dynamics underlying time-serial data. From time-windowed data sets, we construct discrete distribution functions on the phase space. Condition change between base case and test case distribution functions is assessed by dissimilarity measures via L{sub 1}-distance and {chi}{sup 2} statistic. The discriminating power of these measures is first tested on noiseless model data, and then applied for detecting dynamical change in power from a motor-pump system. We compare the phase-space dissimilarities with traditional linear and nonlinear measures used in the analysis of chaotic systems. We also assess the potential usefulness of the new measures for robust, accurate, and timely forewarning of equipment failure.

    Coal burning may enhance human exposure to the natural radionuclides that occur around coal-fired power plants (CFPP). In this study, the spatial distribution and hazard assessment of radionuclides found in soils around a CFPP were investigated using statistics, geostatistics, and geographic information system (GIS) techniques. The concentrations of 226Ra, 232Th, and 40K in soils range from 12.54 to 40.18, 38.02 to 72.55, and 498.02 to 1126.98 Bq kg-1, respectively. Ordinary kriging was carried out to map the spatial patterns of radionuclides, and disjunctive kriging was used to quantify the probability of radium equivalent activity (Raeq) higher than the threshold. The maps show that the spatial variability of the natural radionuclide concentrations in soils was apparent. The results of this study could provide valuable information for risk assessment of environmental pollution and decision support

    Full Text Available Structural elements which are the parts of city identities are shaped as the result of social and cultural characteristics and natural factors. In order to increase visual quality of cities and make cities more liveable landscape architects use not only living materials such as plants but also nonliving materials. This study was carried out to investigate the effects of surrounding elements which are vertical elements in landscape designs, on functional and city aesthetics. With this aim, materials used in surrounding elements around houses in Erzurum, houses surrounded by these elements and their harmony with their surroundings, aesthetics and functional effects were investigated and their contributions to city image were determined. While surrounding elements are mainly adequate in functions, they are lower quality in aesthetics. Some suggestions were offered for the city images that local councils should be careful on and due to Universiade in 2011.

    1995-12-31

    For over three years the Krakow Heat and Power Plant S.A. (ECK SA) has been implementing its strategy of adapting to operation and growth in the market economy. The accomplishment and results of these efforts are presented. The social and economic conditions prevailing during the transformation from a centrally controlled economy to a market economy have changed the realities and regulations that restricted the availability of energy carriers. The continual shortages and restrictions on supplies of gas, electricity, heat and even solids fuels (coke) that occurred in previous years have been replaced by a surplus. That is why many investment planning decisions have had to be revised. A sharp increase in energy carrier prices has required detailed analyses and viability studies to be made before final investment decisions are made. The choice of fuel and heating methods has begun to be dictated by the market and the economy, and not by rationing and administrative decisions. Clearly, a free market in energy generation and distribution has come into existence in the Krakow urban area. In general, these trends will produce a situation in which the fixed cost (depreciation, repairs, payroll) incurred by manufacturers and distributors will be apportioned among a smaller number of power units (MW), thus increasing the capacity price (fixed payment).

  9. Some safeguards considerations for a reference mixed oxide fuel element fabrication plant with an annual throughput of 500 kg PuO2

    International Nuclear Information System (INIS)

    Mixed Oxide (MOX) Fuel Element Fabrication Plants constitute some of the most sensitive facilities in the nuclear fuel cycle from the safeguards point of view as they handle nuclear material in bulk form which could be used directly for the manufacture of nuclear explosive devices. It will therefore be necessary to apply stringent safeguards measures to counter the abrupt and protracted diversion strategies which could be employed in such plants. In order to be capable to detect a protracted diversion a material balance closing with respect to Material Balance Areas (MBA) is required, combined with physical inventory taking, normally including halting of the process operations and collecting nuclear material at Key Measurement Points, conducted by the operator and verified by the Agency. Its frequency, which depends on many parameters, is specified in the facility attachments. This paper discusses one possible approach which is based on interim inventory verifications every two weeks, which do not coincide with closing a material balance and during which part or all of the inventory is verified. This means that the inventories of MBA's are verified at certain Strategic Points which can be accessed without interrupting the process operations, combined with a continual flow verification. This may provide the possibility of deriving a statement with respect to a possible abrupt diversion of nuclear material at a certain probability

    Potential ecosystem effects caused by the effluent cooling water from the Simpevarp nuclear power plant, close to Oskarshamn on the Swedish coast of the Baltic Proper, are monitored in yearly surveys using gillnets and fyke nets. Fishing is undertaken at several sites in a coastal gradient starting at the location of the emitted cooling water, and in a reference area 100 km north of the recipient. Soft bottom macro fauna and macro vegetation are monitored both in the gradient and in the reference area. Fish mortality due to entrapment in the cooling water system and commercial landings are monitored to assess the effects on the local fishery. The water used for cooling is normally heated by 10-12 deg C when passing through the power plant. In sheltered parts of the recipient bay of Hamnefjaerden, the surface water was 4-6 deg C warmer in April-November 2011 than in the reference area comparable reference areas and the emitted water occasionally exceeded 30 deg C in the summer. Fish losses in the cooling water rinsing system were dominated by Baltic herring. Effects on abundances at the population level are estimated to be small, but local effects cannot be ruled out. Perch (Perca fluviatilis), roach (Rutilus rutilus) and silver bream (Blicca bjoerkna) dominated the catches in the surveys with gillnets in Hamnefjaerden, as well as in the archipelago surrounding the power plant. Perch abundances increased in these areas. Catches of roach decreased close to the power plant, but also in the reference area. Perch in the gillnet catches were younger and grew faster close to the power plant than in the reference area. Abnormal gonads, previously observed at high frequencies in perch and roach in Hamnefjaerden, were rare in the 2011 sampling. The abundance of young of the year perch in the recipient did not change over time. The size of the perch fry however, increased in Hamnefjaerden, as well as in the local reference area.

    We conducted pre-sowing seed treatment of spring wheat carbon nanotubes modified with thionyl chloride, ethylene diamine, azobenzole, and dodecylamine. CNTs did not disrupt the structure of the crop, but the activity of extracellular enzymes in the rhizosphere of plants in the flowering stage changed: laccase works more poorly in the variant of the CNTs with the amino groups exochitinase and phosphatase activity increased in the case of chlorinated CNTs, OH and COOH groups on the surface of the nanotubes twice accelerate work β-glucosidase. The changes observed in the biogeochemical cycles in the rhizosphere are a possible cause of the effect of nanotubes on the development of epidemic diseases of wheat.

The DBH of poplar I-72 was larger than that of poplar I-69, but the height of both poplar I-72 and poplar I-69 was similar to each other. These results indicated that the poplar ' Zhonglin46' was not suitable to plant on the beach land of Yangtse river. Although both of the poplarI-72 and poplar I-69 could be used to plant on the beach land, the DBH and volume growth of poplar I-72 were higher than that of poplar I-69 when the planting space was larger.

    The municipal effluents laws to the public wastewater networks are the instruments applied to control the industrial wastewater in Spain. They are very necessary because of the higher pollutant capacity associated to all the industrial effluents discarded to the networks. In this way, every industrial effluents can promote the following problems: aggressiveness to network pipelines and treatment equipment, flow obstruction and presence of novice, dangerous and toxic al substances to both human and biological treatment processes used in the municipal wastewater treatment plant. The control of the industrial effluents in the Cordoba city implies an annual average of 700 inspections in industries, 100 inspections in the main pipeline of city and 5.000 laboratory physical and chemical analysis. All the above said makes possible to control the main industries of the city, to established in the law, also the application of the higher pollution taxes when it is demandable. (Author) 19 refs.

  18. The potential influence of the annual invasive plant, Impatiens glandulifera (Himalayan Balsam), on the hydro-geomorphic functioning of inland river systems

    The invasive plant, Impatiens glandulifera (Himalayan Balsam), is now found in most European countries, as well as across large parts of North America and on some Australasian islands. It favours damp, nutrient-rich soils that experience frequent natural disturbance, such as riparian zones. Its ability to out-compete native vegetation and tendency to suffer rapid dieback during cold weather has led to speculation that it may promote soil erosion, particularly along riverbanks. Despite the strong implication, its ability to promote erosion has only recently been shown during an investigation over one dieback and regrowth cycle along a small watercourse in northwest Switzerland. This presentation now benefits from additional results covering further dieback and regrowth cycles obtained from the same watercourse as above, and from a different river system in southwest UK. These additional results support the original conclusion that I. glandulifera promotes soil erosion along riverbanks and the riparian zone. Importantly, the equivalent ground surface retreat from each group of contaminated locations over the three dieback and regrowth cycles are comparable with erosion in regions where high magnitude events are often recorded. Given these very high erosion rates, albeit over three monitoring phases, it is hypothesised that I. glandulifera may act as a catalyst for repeat cycles of colonisation, dieback and extreme erosion. Aside from the deleterious effect of large quantities of nutrient-rich sediment entering into watercourses, high magnitude soil loss such as this could result in reach-scale sections of riverbank undergoing profound morphological changes and reduced structural stability. Dynamic modifications such as those could ultimately impede the ability of riverbanks to moderate stream flow and offer flood protection, as well as hamper the capacity of riparian zones to buffer and retain sediment and associated contaminants during their passage from terrestrial

    The Kerr Hollow Quarry (KHQ) and the Chestnut Ridge Sediment Disposal Basin (CRSDB) are inactive waste management sites located at the Oak Ridge Y-12 Plant. The KHQ and CRSDB are regulated as treatment, storage, or disposal (TSD) facilities under the Resource Conservation and Recovery Act (RCRA). The facilities were granted interim status in calendar year (CY) 1986 under Tennessee Department of Environment and Conservation (TDEC) Hazardous Waste Management Rule 1200-1-11-.05. Historical environmental monitoring data and baseline characterization under interim status indicated that releases of contaminants to groundwater had not occurred; thus, the detection monitoring was implemented at the sites until either clean closure was completed or post-closure permits were issued. The CRSDB was closed in Cy 1989 under a TDEC-approved RCRA closure plan. A revised RCRA PCPA for the CRSDB was submitted by DOE personnel to TDEC staff in September 1994. A final post-closure permit was issued by the TDEC on September 18, 1995. Closure activities at KHQ under RCRA were completed in October 1993. The Record of Decision will also incorporate requirements of the RCRA post-closure permit once it is issued by the TDEC.

    In 2005, fire ignited by humans swept from Yuma Proving Grounds into Kofa National Wildlife Refuge, Arizona, burning ca. 9,255 ha of Wilderness Area. Fuels were predominantly the native forb Plantago ovata. Large fires at low elevations were rare in the 19th and 20th centuries, and fires fueled by native vegetation are undocumented in the southwestern deserts. We estimated the area damaged by fire using Moderate Resolution Imaging Spectroradiometer and Normalized Difference Vegetation Index, which are more accurate and reduce subjectivity of aerial surveys of perimeters of fires. Assemblages of upland and xeroriparian plants lost 91 and 81% of live cover, respectively, in fires. The trees Olneya tesota and Cercidium had high amounts of top-kill. King Valley was an important xeroriparian corridor for birds. Species richness of birds decreased significantly following the fire. Numbers of breeding birds were lower in burned areas of King Valley 3 years post-fire, compared to numbers in nearby but unburned Alamo Wash. Although birds function within a large geographic scale, the extent of this burn still influenced the relative abundance of local species of breeding birds. This suggests that breeding birds respond to conditions of localized burns and slow recovery of vegetation contributes to continued lower numbers of birds in the burned sites in King Valley.

    International Nuclear Information System (INIS)

    Primary energy demand in Ontario in 1979 was up by 2.9 percent, compared to 2.7 percent in the previous year. Revised forecasts issued in January 1980 indicate Ontario's need for electricity is expected to grow by an average of 3.4 percent annually to the year 2000. Nuclear generation provided 29 percent of the total energy made available by Hydro, and Hydro's eight reactors at Pickering and Bruce continued to rank in the top 36 - four in the top 10 - when compared to the permance of 104 of the world's largest reactors. The provinical legislature's Select Committee on Hydro Affairs examined the safety of the CANDU system and concluded that is is 'acceptably safe'. Faced with reduced forecasts of electrical demands to the year 2000 the Board of Directors decided to stretch out the construction schedule of the Darlington station, to halt construction of the second half of the Bruce Heavy Water Plant D, and to complete but mothball the first half. Construction of Bruce Heavy Water Plant B was completed early in 1979. The A plant produced 599.8 megagrams of reactor-grade heavy water. A control room simulator for Bruce A nuclear generating station was ordered. Agreement was reached on rebuilding faulty boilers at Pickering B. A total of 757.6 megagrams of uranium was used to produce electrical energy and steam. Ontario Hydro continued involvement in uranium exploration. Studies on radioactive waste disposal are being carried out, with emphasis on interim storage and transportation. (LL)

    70 stations, the inversion can meet this requirement. As for major sectoral CO2 emissions, the uncertainties in the inverted emissions using 70 stations are reduced significantly over that obtained using 10 stations by 32 % for commercial and residential buildings, by 33 % for road transport and by 18 % for the production of energy by power plants, respectively. With 70 stations, the uncertainties from the inversion become of 15 % 2-sigma annual uncertainty for dispersed building emissions, and 18 % for emissions from road transport and energy production. The inversion performance could be further improved by optimal design of station locations and/or by assimilating additional atmospheric measurements of species that are co-emitted with CO2 by fossil fuel combustion processes with a specific signature from each sector, such as carbon monoxide (CO. Atmospheric inversions based on continuous CO2 measurements from a large number of cheap sensors can thus deliver a valuable quantification tool for the monitoring and/or the verification of city CO2 emissions (baseline and CO2 emission reductions (commitments.

    The Environmental Evaluation Group (EEG) previously analyzed the probability of a catastrophic accident in the waste hoist of the Waste Isolation Pilot Plant (WIPP) and published the results in Greenfield (1990; EEG-44) and Greenfield and Sargent (1993; EEG-53). The most significant safety element in the waste hoist is the hydraulic brake system, whose possible failure was identified in these studies as the most important contributor in accident scenarios. Westinghouse Electric Corporation, Waste Isolation Division has calculated the probability of an accident involving the brake system based on studies utilizing extensive fault tree analyses. This analysis conducted for the U.S. Department of Energy (DOE) used point estimates to describe the probability of failure and includes failure rates for the various components comprising the brake system. An additional controlling factor in the DOE calculations is the mode of operation of the brake system. This factor enters for the following reason. The basic failure rate per annum of any individual element is called the Event Probability (EP), and is expressed as the probability of failure per annum. The EP in turn is the product of two factors. One is the {open_quotes}reported{close_quotes} failure rate, usually expressed as the probability of failure per hour and the other is the expected number of hours that the element is in use, called the {open_quotes}mission time{close_quotes}. In many instances the {open_quotes}mission time{close_quotes} will be the number of operating hours of the brake system per annum. However since the operation of the waste hoist system includes regular {open_quotes}reoperational check{close_quotes} tests, the {open_quotes}mission time{close_quotes} for standby components is reduced in accordance with the specifics of the operational time table.

  12. Annual Conference SAEE 2010

    International Nuclear Information System (INIS)

    Financing new nuclear power plants in a deregulated market was the issue addressed by the 2010 conference of the Swiss Association for Energy Economics. Stefan Hirschberg of the Paul Scherrer Institute first gave an overview of the internal and external costs of nuclear and other electricity supply technologies. Vincent Rits of the Prognos company presented a worldwide review of the current status of nuclear energy for power production and its prospects, showing that despite the construction of plants at new locations the total installed power will not be significantly different from today's figure, i.e. of the order of 400 GW. This even if the plants built in the 70es and 80es are systematically replaced at the end of their life time by new ones in the next decades. Boris Zuercher of the Avenir Suisse 'think tank' raised the question: 'Are nuclear power plants too big to fail?'. Using arguments from the lessons recently learned from the worldwide financial crisis, he concluded his analysis by pointing out the fact that electricity utilities in Switzerland have already been bailed out by the state, because they are owned by the regional governments and the big cities, even though they are operating as private companies in a (soon completely) deregulated market. Risk management is missing, so Zuercher, and the risks are covered by the state. Benoit Gaillochet of Axa Private Equity presented an appraisal of investments in nuclear power projects by a global financial player. For him, a number of key issues need to be addressed in order to make nuclear projects eligible for infrastructure investors; in particular, the long-term economic viability of these projects is critical. Kaspar Mueller from the Ellipson company critically evaluated future investments in nuclear energy from the financial point of view. The currently available data on the real financial balance of the electric utilities do not provide confidence for future investors. There are serious doubts about

    The U.S. Department of Energy (DOE) Pacific Northwest Site Office (PNSO) oversees and manages the DOE contract for the Pacific Northwest National Laboratory (PNNL), a DOE Office of Science multi-program laboratory located in Richland, Washington. PNSO is responsible for ensuring that all activities conducted on the PNNL site comply with applicable laws, policies, and DOE Orders. The DOE Pacific Northwest Site Office Cultural and Biological Resources Management Plan (DOE/PNSO 2008) addresses the requirement for annual surveys and monitoring for species of concern and to identify and map invasive species. In addition to the requirement for an annual survey, proposed project activities must be reviewed to assess any potential environmental consequences of conducting the project. The assessment process requires a thorough understanding of the resources present, the potential impacts of a proposed action to those resources, and the ultimate consequences of those actions. The PNNL site is situated on the southeastern corner of the DOE Hanford Site, located at the north end of the city of Richland in south-central Washington. The site is bordered on the east by the Columbia River, on the west by Stevens Drive, and on the north by the Hanford Site 300 Area (Figure 1). The environmental setting of the PNNL site is described in Larson and Downs (2009). There are currently two facilities on the PNNL site: the William R. Wiley Environmental Molecular Sciences Laboratory and the Physical Sciences Facility. This report describes the annual survey of biological resources found on the undeveloped upland portions of the PNNL site. The annual survey is comprised of a series of individual field surveys conducted on various days in late May and throughout June 2011. A brief description of the methods PNNL ecologists used to conduct the baseline surveys and a summary of the results of the surveys are presented. Appendix A provides a list of plant and animal species identified in the

    industrialization. The development of small cloud droplets into larger particles requires time. A single thunderstorm cell has a mean development time of about 20 minutes and a life time of around 45 minutes with a mean mind of 10m/s, an air parcel would travel 12 km from the beginning of droplet formation to the first precipitation. That means that the precipitation field is shifted downwind of settlements. It could also explain the the higher frequency of the trace to small amounts observed in Calgary since those events occur under relatively calm weather. Whereas the majority of studies have focused on summer convectional type events, little appears to have been done on the extreme rainfall events on which most structural designs are based. Is there a detectable urban bias in these events? Do urban areas intensify them? What are the implications of point distribution of extreme rainfall events on flood frequency across a city. This paper examines the spatial distribution of the mean annual maximum rainfall event in Calgary, Canada, with a view to determining the relative contribution of geographical setting and urbanisation to point patterns. The data are subsequently maximized to produce maps of probable maximum precipitation for the city. The major results are as follows: (a) position along storm path is the most important variable determining maximum rainfall hazard, (b) higher grounds receive up to seventy percent more maximum rainfall than values based on spatial trend, (c) urban structure and geometry correlate negatively with maximum rainfall intensity, however, (d) zones of maximum flood peaks are found down slope of areas of maximum precipitation increasing flood hazard in the inner city in spite of its lower precipitation. Drainage networks based on point rainfall patterns have proved grossly inadequate for flood mitigation. The new design based on this study recognizes the strong moisture gradients caused by rapid movement of water and other elements down slope. Snow

    Full Text Available The search for identity of cities looks rather urgent and attracts attention of many researchers. Addressing this issue, the article draws an analogy between a human person and a city. Like a city, a human being needs to comprehend his self-identity in order to resist depressive tendencies. It is shown that a person’s depressive symptoms are similar to those of cities. The city identity necessary to resist depression can be searched for both historically and geographically. The historical aspect consists of local myths and legends about the city and the citizens. The geographical aspect of identity comprises features of the terrain, climate, flora and fauna of the region where the city is located.

  12. Environmental Effects of Groundwater Development in Xuzhou City, China

    2006-01-01

    Xuzhou City is located in the most northwestern portion of Jiangsu Province, P. R. China. Karst groundwater in the Ordovician and Cambrian Limestone aquifers is the main source of water supply. There are 527 wells in urban areas to exploit the karst groundwater, yielding up to 35 000 m3 per day. After 1978, urbanization and industrialization of Xuzhou City have continued at a greatly accelerated pace; the population increased from 670 700 (1978) to 1 645 500 (2002), its GDP from 0.71 × 109$ to 42.7×109$ and the urban area from 184 km2 to 1,038 km2 (built-up city area from 41.3 km2 to 81.9 km2). The volume of karst groundwater withdrawal increased yearly before the operation of a supply plant of surface water in 1992, from 3.85×107 m3 (1978) to 1.34×108 m3 (1991) and now maintained at 0.1×109 m3 (2002). Intensive overexploitation of karst groundwater has caused a continuous descending of the piezometric level and the area of the depression cone increases year after year. These changes have increased the vulnerability of the karst groundwater system and have induced environmental problems such as depletion of water resources, water quality deterioration, groundwater contamination and karst collapse. The largest buried depth of karst groundwater is up to 100 m in the dry season in some areas, while 66 exhausted wells have been abandoned. A change in the thickness of the unsaturated zone due to the drawdown of the piezometric level has caused a change of the chemical environment which has an impact on the physical state and major chemical compositions in groundwater. The contents of Ca2+, Mg2+, NO3-, SO42- and Cl- in karst groundwater has increased significantly, total hardness (CaCO3 content) rises annually in most pumping wells and exceeds the Standard of Drinking Water of P.R. China. Point source pollution and belt-like pollution along the rivers has caused water quality deterioration. The sudden loss of buoyant support due to rapid drawdown of the

    During 2006-2010 the National Center for Environmental Research and Training of the National Institute of Ecology of Mexico, carried out several short field studies in the cities of Salamanca, Gto, Tula, Hgo; Guadalajara, Jal; Toluca, Edo Mex; and Tijuana, BC to determine concentration and chemical compositions of PM2.5. These cities, although different in size population have all important industrial and area sources that contribute to high PM2.5 concentrations and therefore potential health impacts. Chemical analyses included organic and elemental carbon for which DRI Model 2001 Thermal/Optical Carbon Analyzer (Atmoslytic Inc, Calabasas, CA, USA) was used. Highest PM2.5 mass mean concentrations were obtained in Salamanca (46 μg/m3), followed by Toluca (43 μg/m3), Guadalajara (37 μg/m3), Tula (20 μg/m3) and Tijuana (18 μg/m3). For Salamanca and Tula, annual levels exceeded the Mexican PM2.5 annual standard of 15 μg/m3. Total carbonaceous aerosol accounted for 41.4%, 41.1%, 32.3%, 29.5% and 29.1% of PM2.5 mass in Tula, Toluca, Guadalajara, Salamanca and Tijuana, respectively. Higher OC2, OC3 and OC4 carbon fractions were observed in Guadalajara, Tijuana and Toluca, indicating an important contribution of gasoline and diesel vehicles emissions in these cities. As for Tula and Salamanca, cities in which refineries and power plants are present, OC3, OC4, EC1 and EC2 represent the higher fractions which could be attributed to stationary sources that use heavy fuels for their combustion process. UNMIX and PMF analyses were used in order to identify the most important sources that contributes to OC and EC concentrations.

    road transport and by 18 % for the production of energy by power plants, respectively. With 70 stations, the uncertainties from the inversion become of 15 % 2-sigma annual uncertainty for dispersed building emissions, and 18 % for emissions from road transport and energy production. The inversion performance could be further improved by optimal design of station locations and/or by assimilating additional atmospheric measurements of species that are co-emitted with CO2 by fossil fuel combustion processes with a specific signature from each sector, such as carbon monoxide (CO). Atmospheric inversions based on continuous CO2 measurements from a large number of cheap sensors can thus deliver a valuable quantification tool for the monitoring and/or the verification of city CO2 emissions (baseline) and CO2 emission reductions (commitments).

    There is an increasing trend to locate fossil-fuel electric generating stations in rural areas. These stations emit large quantities of air pollutants capable of causing serious alterations to the surrounding environment. The major phytotoxic air pollutant emitted is sulfur dioxide (SO/sub 2/). The best way to predict the potential impact of new or expanded sources in rural areas would be to develop a computer model to simulate and predict SO/sub 2/ injury to vegetation. The proposed simulator would provide valuable input information for tasks such as site selection and compilation of environmental impact statements. Such a model would also provide data to management operators for the regulation of emissions. The model would also aid in our basic understanding of the complex interactions which influence plant susceptibility to air pollution. Input to the model would consist of biological and physical data and the output would include the probability of SO/sub 2/ injuring vegetation near existing or proposed sites. The model would be validated using a field situation. This report presents the results obtained during the first year of the project (August 1, 1977 to July 31, 1978).

    Full Text Available Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emission flows broken down into major economic sectors. We examine intercity carbon footprint (CF networks and disclose a hierarchy of responsibility for emissions between cities and regions. Allocations of emissions to households, businesses and government and the carbon efficiency of expenditure have been analysed to inform mitigation policies. Our findings indicate that final demand in the five largest cities in Australia accounts for more than half of the nation’s CF. City households are responsible for about two thirds of the cities’ CFs; the rest can be attributed to government and business consumption and investment. The city network flows highlight that over half of emissions embodied in imports (EEI to the five cities occur overseas. However, a hierarchy of GHG emissions reveals that overseas regions also outsource emissions to Australian cities such as Perth. We finally discuss the implications of our findings on carbon neutrality, low-carbon city concepts and strategies and allocation of subnational GHG responsibility.
