The inclusion of the solubility data in the parametrization has, compared to parameters only parametrized to osmotic coefficients and activity...... coefficients, not significantly affected the deviations of the osmotic coefficients and activity coefficients. The average deviations of the activity coefficient does increase slightly and it was found that the increase in deviations was almost entirely due to reduced accuracy at high temperature and high...... molality. The model is, furthermore, compared to the activity coefficient model, Extended UNIQUAC. It is shown that the eCPA provides more accurate solubility description at higher temperatures than Extended UNIQUAC but also that Extended UNIQUAC is slightly better at describing the activity coefficients...

    Economic immigrants generally, and economic class principal applicants (ECPAs) specifically, tend to have better health than other immigrants. However, health outcomes vary among subcategories within this group, especially by sex. This study examines hospitalization rates among ECPAs aged 25 to 74 who arrived in Canada between 1980 and 2006 as skilled workers, business immigrants, or live-in caregivers. The analysis used two linked databases to estimate age-standardized hospitalization rates (ASHRs) overall and for leading causes by sex. ASHRs of ECPA subcategories were compared with each other and with those of the Canadian-born population. Logistic regression was used to derive odds ratios for hospitalization among ECPAs, by sex. Male and female ECPAs aged 25 to 74 had significantly lower all-cause ASHRs than did the Canadian-born population in the same age range. This pattern prevailed for each ECPA subcategory and for each disease examined. Compared with skilled workers, business immigrants had lower odds of hospitalization; live-in caregivers who arrived after 1992 had higher odds. Adjustment for education, official language proficiency, and world region reduced the strength of or eliminated these associations. Compared with the Canadian-born population, ECPAs generally had low hospitalization rates. Differences were apparent among ECPA subcategories.

    2013-01-01

    Full Text Available Synchronous early-completion-prediction adders (ECPAs are used for high clock rate and high-precision DSP datapaths, as they allow a dominant amount of single-cycle operations even if the worst-case carry propagation delay is longer than the clock period. Previous works have also demonstrated ECPA advantages for average leakage reduction and NBTI effects reduction in nanoscale CMOS technologies. This paper illustrates a general systematic methodology to design ECPA units, targeting nanoscale CMOS technologies, which is not available in the current literature yet. The method is fully compatible with standard VLSI macrocell design tools and standard adder structures and includes automatic definition of critical test patterns for postlayout verification. A design example is included, reporting speed and power data superior to previous works.

  6. The anatomy of hydropower relicensing

    International Nuclear Information System (INIS)

    Mosley, L.W.; Timpe, D.C.

    1991-01-01

    Over 2,000 hydroelectric projects are currently in operation in the United States. Approximately 1,500 of these are regulated by the Federal Energy Regulatory Commission (FERC) with the remainder categorized as either unregulated or owned by the federal government. Of the hydroelectric projects which fall under FERC jurisdiction, licenses for 250 of them are up for renewal between 1991 and 2000. In many cases, the relicensing process has resulted in the expenditure of resources with little apparent payback. Consequently, the ECPA epitaph may reveal that it led to a reduced availability of hydroelectric power-considered to be a relatively clean, environmentally benign source of energy-and, as an added consequence, an increased reliance on fossil fuel-an energy source with its own form of environmental consequences. Unfortunately, it is the American public, the constituency that the ECPA was intended to protect, that will ultimately pay the environmental and financial costs of relicensing. The examples cited in this paper describe cases in which the effectiveness of the ECPA is questionable

    Plasma-etched nanoclay-reinforced Polyamide 12 (PA12) powder is prepared with its intended use in selective laser sintering (LS) applications. To replicate the LS process we present a downward heat sintering (DHS) process, carried out in a hot press, to fabricate tensile test specimens from the composite powders. The DHS parameters are optimized through hot stage microscopy, which reveal that the etched clay (EC)-based PA12 (EC/PA12) nanocomposite powder melts at a temperature 2°C higher than that of neat PA12, and 1-3°C lower than that of the nonetched clay-based nanocompsite (NEC/PA12 composite). We show that these temperature differences are critical to successful LS. The distribution of EC and NEC onto PA12 is investigated by scanning electron microscopy (SEM). SEM images show clearly that the plasma treatment prevents the micron-scale aggregation of the nanoclay, resulting in an improved elastic modulus of EC/PA12 when compared with neat PA12 and NEC/PA12. Moreover, the reduction in elongation at break for EC/PA12 is less pronounced than for NEC/PA12.

    The miscibility of ethyl cellulose (EC)/copolyamide6/66/1010 (PA-130) in formic acid is studied by viscometry and refractive index techniques at 25°C. Using viscosity data, the criteria Δ b, Δ b', Δ[η]m, interaction parameter μ, β and thermodynamic parameter α are calculated. These investigations indicate that blend of EC/PA-130 is miscible when the ethyl cellulose content is more than 50 wt % in the blend. Further the result was also confirmed by refractive index measurements.

    1980-05-01

    Titles I and III of the Public Utility Regulatory Policies Act of 1978 (PURPA) establish retail regulatory policies for electric and natural gas utilities, respectively, aimed at achieving three purposes: conservation of energy supplied by electric and gas utilities; efficiency in the use of facilities and resources by these utilities; equitable rates to electricity and natural gas consumers. PURPA also continues the pilot utility implementation program, authorized under Title II of the Energy Conservation and Production ACT (ECPA), to encourage adoption of cost-based rates and efficient energy-management practices. The purpose of this report is twofold: (1) to summarize and analyze the progress that state regulatory authorities and certain nonregulated utilities have made in their consideration of the PURPA standards; and (2) to summarize the Department of Energy (DOE) activities relating to PURPA and ECPA. The report provides a broad overview and assessment of the status of electric and gas regulation nationwide, and thus helps provide the basis for congressional and DOE actions targeted on the utility industry to address pressing national energy problems.

    Full Text Available The first conference the European Commission on Preservation and Access (ECPA organized, 'Choosing to preserve', took place in Leipzig in 1996. For the keynote lecture we had invited a scholar, Professor Bernhard Fabian. This was a very deliberate choice, as the ECPA subscribed to the view that academic researchers, as users of the resources kept in libraries and archives, have to be involved in discussions about their preservation. The conference had attracted quite a crowd, around 150 people who were of course all there for the opening lecture. We invited Professor Fabian because he was a very good speaker, who could really present a convincing case to an audience, which he did also on that occasion. He devoted a large part of his presentation of 45 minutes to the horrors of microfilm, showing us pictures of illegible film, with bits missing, that was impossible to use. He explained how distressing it was for scholars to be forced to use surrogates that don't do justice to the originals that they need to study.

    Section 304(b) of the Energy Conservation and Production Act (ECPA), as amended, requires the Secretary of Energy to make a determination each time a revised version of ASHRAE Standard 90.1 is published with respect to whether the revised standard would improve energy efficiency in commercial buildings. When the U.S. Department of Energy (DOE) issues an affirmative determination on Standard 90.1, states are statutorily required to certify within two years that they have reviewed and updated the commercial provisions of their building energy code, with respect to energy efficiency, to meet or exceed the revised standard. This report provides a preliminary qualitative analysis of all addenda to ANSI/ASHRAE/IES Standard 90.1-2010 (referred to as Standard 90.1-2010 or 2010 edition) that were included in ANSI/ASHRAE/IES Standard 90.1-2013 (referred to as Standard 90.1-2013 or 2013 edition).

    The purpose of this analysis is to assess the relative energy and energy cost performance of commercial buildings designed to meet the requirements found in the commercial energy efficiency provisions of the International Energy Conservation Code (IECC). Section 304(b) of the Energy Conservation and Production Act (ECPA), as amended, requires the Secretary of Energy to make a determination each time a revised version of ASHRAE Standard 90.1 is published with respect to whether the revised standard would improve energy efficiency in commercial buildings. As many states have historically adopted the IECC for both residential and commercial buildings, PNNL has evaluated the impacts of the commercial provisions of the 2006, 2009, and 2012 editions of the IECC. PNNL also compared energy performance with corresponding editions of ANSI/ASHRAE/IES Standard 90.1 to help states and local jurisdictions make informed decisions regarding model code adoption.

  14. Electrolyte CPA equation of state for very high temperature and pressure reservoir and basin applications

    Courtial, Xavier; Ferrando, Nicolas; de Hemptinne, Jean-Charles; Mougin, Pascal

    2014-10-01

    In this work, an electrolyte version of the Cubic Plus Association (eCPA) equation of state has been adapted to systems containing CH4, CO2, H2O and NaCl (up to 5 molal) at pressures up to 200 MPa and temperatures up to 773 K for salt-free systems and 573 K for salt-containing systems. Its purpose is to represent the phase behavior (including salting-out effect and critical point) and the phase densities in a range of temperature and pressure encountered in deep reservoirs and basins. The goal of the parameterization proposed is not to reach a very high accuracy for phase equilibrium and volumetric properties, but rather to develop a semi-predictive approach to model the phase and volumetric behavior of this system while allowing an easy extension to other compounds. Without salt, predictions for pure component vapor pressures and liquid molar volumes present an average absolute deviation (AAD) lower than 3% compared to experimental reference values. The pure component molar volumes out of saturation show an AAD lower than 4%. The highest deviations in densities are observed as expected in the vicinity of the critical coordinates of pure water and this effect increases when gases or salts are added to the system. For each binary system, CH4 + CO2, CH4 + H2O and CO2 + H2O, binary interaction parameters have been fitted to correctly represent the shape of the fluid phase envelopes (including all critical points) in the entire temperature and pressure range considered (219 K to 633 K and up to 250 MPa). The methane concentration in both phases of the CH4 + CO2 binary system is represented with an AAD lower than 9%. The methane solubility in water is represented within 16% and 8% for the methane content of the vapor. The CO2 solubility in water is within 26%, while the CO2 in the vapor phase shows an average deviation of 12%. All molar volumes are represented with an AAD lower than 3%. The few VLE experimental data for the CH4 + CO2 + H2O ternary system are fairly well

    Market presence of illegal and counterfeit pesticides is now a global problem. According to data published in 2012 by the European Crop Protection Association (ECPA), illegal products represent over 10% of the global market of plant protection products. Financial benefits are the main reason for the prevalence of this practice. Counterfeit and illegal pesticides may contain substances that may pose a threat to the environment, crops, animals, and humans, inconsistent with the label and registration dossier. In Poland, action against illegal and counterfeit plant protection products is undertaken by the Main Inspectorate of Plant Health and Seed Inspection (PIORiN), the police, the prosecution, and the pesticide producers. Results of chemical analyses carried out by the Institute of Plant Protection - National Research Institute Sośnicowice Branch, Pesticide Quality Testing Laboratory (PQTL IPP-NRI Sosnicowice Branch) indicate that a majority of illegal pesticides in Poland are detected in the group of herbicides. Products from parallel trade tend to have the most irregularities. This article describes the official quality control system of plant protection products in Poland and presents the analytical methods for testing pesticides suspected of adulteration and recent test results.

    Full Text Available Emergency contraception pills (ECP are among the 13 essential commodities in the framework for action established by the UN Commission on Life-Saving Commodities for Women and Children. Despite having been on the market for nearly 20 years, a number of barriers still limit women's access to ECP in low- and middle-income countries (LMIC including limited consumer knowledge and poor availability. This paper reports the results of a review to synthesise the current evidence on service delivery strategies to improve access to ECP.A narrative synthesis methodology was used to examine peer reviewed research literature (2003 to 2013 from diverse methodological traditions to provide critical insights into strategies to improve access from a service delivery perspective. The studies were appraised using established scoring systems and the findings of included papers thematically analysed and patterns mapped across all findings using concept mapping.Ten papers were included in the review. Despite limited research of adequate quality, promising strategies to improve access were identified including: advance provision of ECP; task shifting and sharing; intersectoral collaboration for sexual assault; m-health for information provision; and scale up through national family planning programs.There are a number of gaps in the research concerning service delivery and ECP in LMIC. These include a lack of knowledge concerning private/commercial sector contributions to improving access, the needs of vulnerable groups of women, approaches to enhancing intersectoral collaboration, evidence for social marketing models and investment cases for ECP.

    Surface water can be contaminated by bacteria from various sources, including manure from agricultural facilities. Attachment of these bacteria to soil and organic particles contributes to their transport through the environment, though the mechanism of attachment is unknown. As bacterial attachment to human tissues is known to be correlated with antibiotic resistance, we have investigated here the relationship between bacterial attachment to environmental particles and antibiotic resistance in agricultural isolates. We evaluated 203 Escherichia coli isolates collected from swine facilities for attachment to quartz, resistance to 13 antibiotics, and the presence of genes encoding 13 attachment factors. The genes encoding type I, EcpA, P pili, and Ag43 were detected, though none was significantly related to attachment. Quartz attachment was positively and significantly (P amoxicillin/streptomycin/tetracycline/sulfamethazine/tylosin/chlortetracycline and negatively and significantly (P < 0.0038) related to combined resistance to nalidixic acid/kanamycin/neomycin. These results provide clear evidence for a link between antibiotic resistance and attachment to quartz in agricultural isolates. We propose that this may be due to encoding by the responsible genes on a mobile genetic element. Further exploration of the relationship between antibiotic resistance and attachment to environmental particles will improve the understanding and modeling of environmental transport processes, with the goal of preventing human exposure to antibiotic-resistant or virulent microorganisms.

    Full Text Available In August 1997 the first of a series of summer schools in Preservation Management was held at the Archivschule in Marburg (Germany. The school was organised by the ECPA, the LIBER Division on Preservation, ICA and the Archivschule itself and was aimed at archivists and librarians in management positions from European institutions. It dealt with managerial, organisational and financial aspects of preservation and required active participation by those attending. Apart from introductory sessions by the teaching staff at the Archivschule, a large part of the course took the form of working groups, discussions, assignments and role play, to which participants were expected to take their own experience and problems. The school was conducted in German. Topics, spread over five days, ranged from preservation in the context of the core activities of libraries and archives; planning of preservation projects; general management issues, such as resource management, budgeting, priority setting, communication and effecting change; to more detailed considerations of day-to-day issues, such as storage, disaster control, microfilming and digitising, mass conservation processes, and moulds and fungi.

    1996-12-31

    The final energy consumption in Thailand increased at about ten percent annually within the last 10 years. To slow the energy demand growth rate while maintaining the country`s economic advance and environmental sustainability, the Energy Conservation Promotion Act (ECPA) was adopted in 1992. With this Act, a comprehensive Energy Conservation Program (ENCON) was initiated. ENCON commits the government to promoting energy conservation, to developing appropriate regulations, and to providing financial and organizational resources for program implementation. Due to this existing ENCON program a great benefit is expected not only to reducing energy consumption, but also to decreasing GHGs emissions substantially. This study is a part of the ENCON research program which was supported by the German Federal Government under the program called Prompt-Start Measures to Implement the U.N. Framework Convention on Climate Change (FCCC). The basic activities carried out during the project included (1) An assessment of Thailand`s total and specific energy consumption in the industrial sectors and commercial buildings; (2) Identification of existing and candidate technologies for GHG emission reduction and energy efficiency improvements in specific factories and commercial buildings; and (3) Identification of individual factories and commercial buildings as candidates for detailed further study. Although the energy assessment had been carried out for the commercial buildings also, this paper will cover only the work on the manufacturing sector. On the basis of these steps, 14 factories were visited by the project team and preliminary energy audits were performed. As a result, concrete measures and investments were proposed and classified into two groups according to their economic characteristics. Those investments with a payback time of less than four years were considered together in a Moderate scenario, and those with longer payback times in an Intensive scenario.

    In Escherichia coli, the common pilus (Ecp) belongs to an alternative chaperone–usher pathway that plays a major role in both early biofilm formation and host-cell adhesion. Initial attempts at crystallizing the chaperone EcpB using natively purified protein from the bacterial periplasm were not successful; however, after the isolation of EcpB under denaturing conditions and subsequent refolding, crystals were obtained at pH 8.0 using the sitting-drop method of vapour diffusion. This is the first time that this refolding strategy has been used to purify CU chaperones. Pili are key cell-surface components that allow the attachment of bacteria to both biological and abiotic solid surfaces, whilst also mediating interactions between themselves.

    Despite the increased interest in exercise dependence, there is limited research examining the personality characteristics of exercise dependent individuals. Furthermore, researchers examining the relationship between exercise dependence and personality have found inconsistent results. This maybe the result of the varying methods used by researchers to assess exercise dependence and personality. The purpose of this study was to examine the relationship between exercise dependence and personality, and that determine whether there is an addictive personality type. Participants were 484 university students (M=21.24, SD=3.03), and 322 sport leisure participants (M=30.08, Sd=13.58) who completed multidimensional assessments of exercise dependence and personality. to assess exercise dependence, the EDS-R (French version, Kern, L, 2007, Validation de l'adaptation française de l'échelle de dépendance à l'exercice physique : l'EDS-R Pratiques Psychologiques, 13, 4, 425-441) was undertaken. This scale is based on the DSM_IV criteria for substance dependence which are: withdrawal effects, intention effects, lack of control, time, reductions in other activities, continuance. The D5D was chosen to assess the big five personality dimensions (Rolland, J.-P., & Mogenet, J.-L. (1994). Manuel du système d5d. Paris: ECPA.). These dimensions are: Extraversion, Emotional Stability, Agreeableness, Conscientiousness, and Openness to Experience. To examine the predictive relationship of personality for exercise dependence symptoms, a series of multiple regressions was carried out. Results show that, according to the status of the people under scrutiny, it is either openness to experience and emotional stability or openness to experience and agreeableness which explain the greatest variance of exercise dependence. Then, the description of a personality type seemed very difficult to obtain. We feel it's important to know the personality type, but not sufficient; it is more pertinent to

    The aim of this study was to investigate the prevalence of diarrheagenic E. coli strains in vegetables from the humid Pampa region, Argentina, and to determine the occurrence of serotypes and virulence genes in the isolates. A total of 373 fresh vegetable samples obtained from 41 different geographical points were examined. E. coli was detected in 38.6% of the samples. Ten isolates could be obtained from 14 samples presumptively positive for diarrheagenic E. coli: 8 were identified as atypical Enteropathogenic E. coli (aEPEC) and 2 as Verocytotoxigenic E. coli (VTEC). Lettuce and beet were the vegetables most frequently contaminated with pathogenic E. coli. The isolates belonged to serotypes O1:H7, O28:H19, O39:H40, O86:H31, O132:H8, O139:H20, O178:H7 and O178:H19, some of which reportedly have caused human illness, and one isolate resulted non typeable. Taking into account the distribution of 16 nle genes, 7 profiles were detected. On the other hand, all tested isolates harbored the gene encoding for the adhesin HcpA. Other adhesion related genes were also identified: ecpA and elfA were detected in 90%, lpfA 0113 in 60%, and ehaA in 50% of the isolates meanwhile ihaA was only observed in O178:H19 isolate. This VTEC isolate harbored, also, Cdt-V toxin and megaplasmid encoding genes such as espP, subA and epeA and exhibited a strong cytotoxic effect. These data is the first molecular E. coli report that confirms the presence of E. coli pathotypes circulating among vegetables in Argentina. Genetic characterization showed that in addition to eae or vtx genes, isolates obtained from vegetables harbored genes encoding other toxins, adhesins, and components related to the type III secretion system that could contribute to their virulence. In conclusion, this research shows that vegetables in Argentina may be the source of VTEC and EPEC infections in the community and therefore, they should be considered as vehicles for transmission of these potentially pathogenic

    Over the last decades rainfall has become more intense in Sicily, making large proportions of steeply sloping agricultural land more vulnerable to soil erosion, mainly orchards and vineyards (Diodato and Bellocchi 2010). The prevention of soil degradation is indirectly addressed in the European Union's Water Framework Directive (2000/60/EC) and Sustainable Use Directive (2009/128/EC). As a consequence, new EU compliance conditions for food producers requires them to have tools and solutions for on-farm implementation of sustainable practices (Singh et al. 2014). The Agricultural Runoff and Best Management Practice Tool has been developed by Syngenta to help farm advisers and managers diagnose the runoff potential from fields with visible signs of soil erosion. The tool consists of 4 steps including the assessment of three key landscape factors (slope, topsoil permeability and depth to restrictive horizon) and 9 mainly soil and crop management factors influencing the runoff potential. Based on the runoff potential score (ranging from 0 to 10), which is linked to a runoff potential class, the Runoff Tool uses in-field and edge-of-the-field Best Management Practices (BMPs) to mitigate runoff (aligned with advice from ECPA's TOPPS-prowadis project). The Runoff tool needs testing in different regions and crops to create a number of use scenarios with regional/crop specific advice on BMPs. For this purpose the Tool has been tested in vineyards of the Tasca d'Almerita and Planeta wineries, which are large family-owned estates with long-standing tradition in viticulture in Sicily. In addition to runoff potential scores, Visual Soil Assessment (VSA) scores have been calculated to allow for a comparison between different diagnostic tools. VSA allows for immediate diagnosis of soil quality (a higher score means a better soil quality) including many indicators of runoff (Shepherd 2008). Runoff potentials were moderate to high in all tested fields. Slopes were classified as
